PART I.

ITEM 1.     BUSINESS

THE COMPANY

CHS Inc. (referred to herein as "CHS," "we" or "us") is one of the nation's leading integrated agricultural companies, providing grain, foods and energy resources to businesses and consumers on a global basis. As a cooperative, we are owned by farmers and ranchers and their member cooperatives (referred to herein as "members") across the United States. We also have preferred stockholders that own shares of our 8% Cumulative Redeemable Preferred Stock, our Class B Cumulative Redeemable Preferred Stock, Series 1 ("Class B Series 1 Preferred Stock"), our Class B Reset Rate Cumulative Redeemable Preferred Stock, Series 2 ("Class B Series 2 Preferred Stock"), our Class B Reset Rate Cumulative Redeemable Preferred Stock, Series 3 ("Class B Series 3 Preferred Stock") and our Class B Cumulative Redeemable Preferred Stock, Series 4 ("Class B Series 4 Preferred Stock") listed on the NASDAQ Stock Market LLC ("NASDAQ") under the symbols CHSCP, CHSCO, CHSCN, CHSCM and CHSCL, respectively. We buy commodities from and provide products and services to patrons (including our members and other non-member customers), both domestic and international. We provide a wide variety of products and services, from initial agricultural inputs such as fuels, farm supplies, crop nutrients and crop protection products, to agricultural outputs that include grains and oilseeds, grain and oilseed processing, renewable fuels and food products. A portion of our operations are conducted through equity investments and joint ventures whose operating results are not fully consolidated with our results; rather, a proportionate share of the income or loss from those entities is included as a component in our net income under the equity method of accounting. For the year ended August 31, 2015 , our total revenues were $34.6 billion and net income attributable to CHS Inc. was approximately $781.0 million .

We have aligned our segments based on an assessment of how our businesses operate and the products and services they sell.

Our Energy segment derives its revenues through refining, wholesaling and retailing of petroleum products. Our Ag segment derives its revenues through the origination and marketing of grain, including service activities conducted at export terminals; through wholesale sales of crop nutrients; from sales of soybean meal, soybean refined oil and soyflour products; through the production and marketing of renewable fuels; and through retail sales of petroleum and agronomy products, processed sunflowers, feed and farm supplies. Our Ag segment also records equity income from investments in our grain export joint venture and other investments. We include other business operations in Corporate and Other because of the nature of their products and services, as well as the relative revenues of those businesses. These businesses primarily include our financing, insurance, hedging and other service activities related to crop production. In addition, our wheat milling and packaged food operations are included in Corporate and Other, as those businesses are conducted through non-consolidated joint ventures.

Many of our business activities are highly seasonal and operating results vary throughout the year. Our income is generally lowest during our second fiscal quarter and highest during our third fiscal quarter. For example, in our Ag segment, our crop nutrients and country operations businesses generally experience higher volumes and income during the spring planting season and in the fall, which corresponds to harvest. Our grain marketing operations are also subject to fluctuations in volume and earnings based on producer harvests, world grain prices and demand. Our Energy segment generally experiences higher volumes and profitability in certain operating areas, such as refined products, in the summer and early fall when gasoline and diesel fuel usage is highest and is subject to domestic supply and demand forces. Other energy products, such as propane, may experience higher volumes and profitability during the winter heating and crop drying seasons.

Our earnings from cooperative business are allocated to members (and to a limited extent, to non-members with which we have agreed to do business on a patronage basis) based on the volume of business they do with us. We allocate these earnings to our patrons in the form of patronage refunds (which are also called patronage dividends) in cash and patrons' equities (capital equity certificates), which may be redeemed over time solely at the discretion of our Board of Directors. Earnings derived from non-members, which are not treated as patronage, are taxed at federal and state statutory corporate rates and are retained by us as unallocated capital reserve. We also receive patronage refunds from the cooperatives in which we are a member, if those cooperatives have earnings to distribute and if we qualify for patronage refunds from them.

Our origins date back to the early 1930s with the founding of the predecessor companies of Cenex, Inc. and Harvest States Cooperatives. CHS Inc. emerged as the result of the merger of those two entities in 1998, and is headquartered in Inver Grove Heights, Minnesota.

Our segment and international sales information in Note 11, Segment Reporting of the Notes to Consolidated Financial Statements, as well as Item 6 of this Annual Report on Form 10-K, are incorporated by reference into the following segment descriptions.

The segment financial information presented below may not represent the results that would have been obtained had the relevant segment been operated as an independent business due to efficiencies in scale, corporate cost allocations and intersegment activity.

Our internet address is www.chsinc.com. The information contained on our website is not part of, and is not incorporated in, this report or any other report we file with or furnish to the Securities and Exchange Commission.

ENERGY

Overview

We are the nation's largest cooperative energy company based on revenues and identifiable assets, with operations that include petroleum refining and pipelines; the supply, marketing and distribution of refined fuels (gasoline, diesel fuel and other energy products); the blending, sale and distribution of lubricants; and the wholesale supply of propane and other natural gas liquids. Our Energy segment processes crude oil into refined petroleum products at refineries in Laurel, Montana (wholly-owned) and McPherson, Kansas (an entity which became wholly owned as of September 1, 2015) and sells those products under the Cenex ® brand to member cooperatives and other independent retailers through a network of nearly 1,500 sites, the majority of which are convenience stores marketing Cenex ® branded fuels. For fiscal 2015 , our Energy revenues, after elimination of inter-segment revenues, were $8.2 billion and were primarily from gasoline and diesel fuel.

Operations

Laurel Refinery.   Our Laurel, Montana refinery processes medium and high sulfur crude oil into refined petroleum products that primarily include gasoline, diesel fuel, petroleum coke and asphalt. Our Laurel refinery sources approximately 90% of its crude oil supply from Canada, with the balance obtained from domestic sources, and we have access to Canadian and northwest Montana crude through our wholly-owned Front Range Pipeline, LLC and other common carrier pipelines. Our Laurel refinery also has access to Wyoming crude via common carrier pipelines from the south.

Our Laurel facility processes approximately 55,000 barrels of crude oil per day to produce refined products that consist of approximately 42% gasoline, 41% diesel fuel and other distillates, 5% petroleum coke, and 11% asphalt and other products. Refined fuels produced at Laurel are available via rail cars and the Yellowstone Pipeline to western Montana terminals and to Spokane and Moses Lake, Washington; south via common carrier pipelines to Wyoming terminals and Denver, Colorado; and east via our wholly-owned Cenex Pipeline, LLC to Glendive, Montana, and Minot and Fargo, North Dakota.

McPherson Refinery.   As of August 31, 2015, we owned approximately 88.9% of the McPherson, Kansas refinery which was owned and operated by National Cooperative Refinery Association ("NCRA"). In September 2015, we became the sole owner of the McPherson refinery upon the final closing under our November 2011 agreement to purchase the noncontrolling interests in NCRA which is now known as CHS McPherson Refinery Inc. ("CHS McPherson"). See Note 17, Acquisitions , to our audited consolidated financial statements included in this Annual Report on Form 10-K for additional information. The McPherson refinery processes approximately 80% low and medium sulfur crude oil and 20% heavy sulfur crude oil into gasoline, diesel fuel and other distillates, propane and other products. The refinery sources its crude oil through its own pipelines as well as common carrier pipelines. The low and medium sulfur crude oil is sourced from Kansas, North Dakota, Oklahoma and Texas, and the heavy sulfur crude oil is sourced from Canada.

Our McPherson refinery processes approximately 85,000 barrels of crude oil per day to produce refined products that consist of approximately 51% gasoline, 44% diesel fuel and other distillates, and 2% propane and other products. Approximately 29% of the refined fuels are loaded into trucks at the McPherson refinery or shipped via its proprietary products pipeline to our terminal in Council Bluffs, Iowa. The remaining refined fuel products are shipped to other markets via common carrier pipelines.

Other Energy Operations.   We own six propane terminals, four asphalt terminals, seven refined product terminals and three lubricants blending and packaging facilities. We also own and lease a fleet of liquid and pressure trailers and tractors, which are used to transport refined fuels, propane, anhydrous ammonia and other products.

Products and Services

Our Energy segment produces and sells (primarily wholesale) gasoline, diesel fuel, propane, asphalt, lubricants and other related products and provides transportation services. In addition to selling the products refined at our Laurel and McPherson refineries, we purchase products from third parties. For fiscal 2015, we obtained approximately 53% of the refined products we sold from our Laurel and McPherson refineries, and approximately 47% from third parties.

Sales and Marketing; Customers

We market approximately 80% of our refined fuel products to members, with the balance sold to non-members. Sales are made wholesale to member cooperatives and through a network of independent retailers that operate convenience stores under the Cenex trade name. We sold approximately 1.4 billion gallons of gasoline and approximately 1.9 billion gallons of diesel fuel in fiscal 2015, excluding CHS McPherson's (then known as NCRA) sales to minority owners and others totaling approximately 127 million gallons. We also blend, package and wholesale auto and farm machinery lubricants to both members and non-members. We are one of the nation's largest propane wholesalers based on revenues. Most of the propane sold in rural areas is for heating and agricultural usage. Annual sales volumes of propane vary greatly depending on weather patterns and crop conditions.

Industry; Competition

The petroleum business is highly cyclical. Demand for crude oil and energy products is driven by the condition of local and worldwide economies, local and regional weather patterns and taxation relative to other energy sources, which can significantly affect the price of refined fuel products. Most of our energy product market is located in rural areas, so sales activity tends to follow the planting and harvesting cycles. More fuel-efficient equipment, reduced crop tillage, depressed prices for crops, weather conditions and government programs which encourage idle acres, may all reduce demand for our energy products.

Regulation.   Governmental regulations and policies, particularly in the areas of taxation, energy and the environment, have a significant impact on our Energy segment. Our Energy segment's operations are subject to laws and related regulations and rules designed to protect the environment that are administered by the Environmental Protection Agency ("EPA"), the Department of Transportation ("DOT") and similar government agencies. These laws, regulations and rules govern the discharge of materials into the environment, air and water; reporting storage of hazardous wastes and other hazardous materials; the transportation, handling and disposal of wastes and other materials; the labeling of pesticides and similar substances; and investigation and remediation of releases of hazardous materials. Failure to comply with these laws, regulations and rules could subject us to administrative penalties, injunctive relief, civil remedies and possible recalls of products. Our hedging transactions and activities are subject to the rules and regulations of the exchanges we use, including the Chicago Mercantile Exchange ("CME"), as well as the U.S. Commodity Futures Trading Commission ("CFTC").

Competition.   The petroleum refining and wholesale fuels business is very competitive. Among our competitors are some of the world's largest integrated petroleum companies, which have their own crude oil supplies, distribution and marketing systems. We also compete with smaller domestic refiners and marketers in the midwestern and northwestern United States, with foreign refiners who import products into the United States and with producers and marketers in other industries supplying other forms of energy and fuels to consumers. Given the commodity nature of the end products, profitability in the refining and marketing industry depends largely on margins, as well as operating efficiency, product mix and costs of product distribution and transportation. The retail gasoline market is highly competitive, with much larger competitors that have greater brand recognition and distribution outlets throughout the country and the world. Our owned and non-owned retail outlets are located primarily in the northwestern, midwestern and southern United States.

We market refined fuels products in five principal geographic areas. The first area includes the Midwest and northern plains. Competition at the wholesale level in this area includes major oil companies, including Phillips 66, Shell, Tesoro and BP as well as independent refiners and wholesale brokers/suppliers. This area has a robust spot market and is influenced by the large refinery center along the gulf coast. The majority of the product moved in this market is shipped on the Magellan and NuStar pipeline systems.

To the east of the Midwest and northern plains is another unique marketing area. This area centers near Chicago, Illinois and includes eastern Wisconsin, Illinois and Indiana. We principally compete with the major oil companies Marathon, BP, ExxonMobil and Citgo as well as independent refineries and wholesale brokers/suppliers.

Another market area is located south of Chicago, Illinois. Most of this area includes Arkansas, Missouri and the northern part of Texas. Competition in this area includes the major oil companies Phillips 66, Valero and ExxonMobil and independent refiners. This area is principally supplied from the Gulf coast refinery center and is also driven by a strong spot market that reacts quickly to changes in the international and national supply balance.

Another geographic area includes Montana, western North Dakota, Wyoming, Utah, Idaho, Colorado and western South Dakota. Competition at the wholesale level in this area includes the major oil companies ExxonMobil, Phillips 66 and Tesoro and independent refiners. This area is also noted for being fairly well balanced in demand and supply, but has in recent times been impacted by the large growth of demand from the Bakken crude activity in this region.

The last area includes much of Washington and Oregon. We compete with the major oil companies Phillips 66, Tesoro, BP and Chevron in this area. This area is also known for volatile prices and an active spot market.

AG

Our Ag segment includes our crop nutrients, country operations, grain marketing, renewable fuels and processing and food ingredients businesses. In fiscal 2015, revenues in our Ag segment were $26.3 billion consisting principally of grain sales of $17.2 billion after elimination of inter-segment revenues.

Grain Marketing

Overview

We are the nation's largest cooperative marketer of grain and oilseed based on grain storage capacity and grain sales, handling over 2.0 billion bushels annually. During fiscal 2015 , we purchased approximately half of our total grain volumes from individual and cooperative association members and our country operations business, with the balance purchased from third parties. We arrange for the transportation of the grains either directly to customers or to our owned or leased grain terminals and elevators awaiting delivery to domestic and foreign purchasers. We primarily conduct our grain marketing operations directly, but do conduct some of our business through TEMCO, LLC ("TEMCO"), a 50% joint venture with Cargill.

Operations

Our grain marketing operations purchase grain directly and indirectly from agricultural producers primarily in the midwestern and western United States. The purchased grain is typically contracted for sale for future delivery at a specified location, and we are responsible for handling the grain and arranging for its transportation to that location. The sale of grain is recorded after title to the commodity has transferred and final weights, grades and settlement price have been agreed upon. Amounts billed to the customer as part of a sales transaction include the costs for shipping and handling. Our ability to arrange efficient transportation, including loading capabilities onto unit trains, ocean-going vessels and barges, is a significant part of the services we offer to our customers. Rail, vessel, barge and truck transportation is carried out by third parties, often under long-term freight agreements with us. Grain intended for export is usually shipped by rail or barge to an export terminal, where it is loaded onto ocean-going vessels. Grain intended for domestic use is usually shipped by rail or truck to various locations throughout the country.

We own and operate export terminals, river terminals and elevators involved in the handling and transport of grain and grain products. Our river terminals are used to load grain onto barges for shipment to both domestic and export customers via the Mississippi River system. These river terminals are located at Savage and Winona, Minnesota; Davenport, Iowa; and Pekin, Illinois as well as terminals in which we have put-through agreements located at St. Louis, Missouri and Beardstown and Havana, Illinois. Our export terminal at Superior, Wisconsin provides access to the Great Lakes and St. Lawrence Seaway, and our export terminal at Myrtle Grove, Louisiana serves the Gulf of Mexico market. In the Pacific Northwest, we conduct our grain marketing operations through TEMCO which operates export terminals in Tacoma, Washington; Kalama, Washington; and Portland, Oregon and primarily exports wheat, corn and soybeans. These facilities serve the Pacific market. We also own two 110-car shuttle-receiving elevator facilities in Friona, Texas and Collins, Mississippi that serve large-scale feeder cattle, dairy and poultry producers in those regions.

For sourcing and marketing grains and oilseeds through the Black Sea, Mediterranean Basin and Middle East regions to customers worldwide we have offices in Geneva, Switzerland; Barcelona, Spain; Kiev, Ukraine; Krasnodar, Russia; Novi Sad, Serbia; Bosanski Samac, Bosnia; Bucharest, Romania; Sofia, Bulgaria; and marketing offices in Amman, Jordan and Istanbul, Turkey. We have a deep water port in Constanta, Romania, a barge loading facility on the Danube River in Giurgiu,

Romania, three inland terminals in Bosnia, three inland terminals in Russia and an inland grain terminal at Oroshaza, Hungary (leased to a joint venture). We have an investment in a port facility in Odessa, Ukraine.

In the Pacific Rim area, we have marketing offices in Singapore; Seoul, South Korea; Taipei, Taiwan; and Shanghai, China that serve customers receiving grains and oilseeds from our origination points in North America, South America, Australia and the Black Sea regions. In Australia we have investments in inland grain storage facilities and container packaging and logistics facilities.

In South America we have grain merchandising offices to source grains in Sao Paulo, Brazil; Ciudad de Este, Paraguay; Montevideo, Uruguay; and Buenos Aires, Argentina. In Brazil we have an investment in a deep water port facility in Itaqui Port. In Argentina, we own a fertilizer warehouse in the Necochea area, have an investment in a deep water port facility in Necochea and have an investment in a sunflower processing facility.

Finally, we sell and market crop nutrients from our Geneva, Switzerland; Singapore; Sao Paulo, Brazil; Ciudad de Este, Paraguay; and Buenos Aires, Argentina offices.

Our grain marketing operations may have significant working capital needs, at any time, depending on commodity prices and other factors. The amount of borrowings for this purpose, and the interest rate charged on those borrowings, directly affects the profitability of our grain marketing operations.

Products and Services

Our grain marketing operations purchased approximately 2.0 billion bushels of grain during the year ended August 31, 2015 , which primarily included corn, soybeans, wheat and distillers dried grains with solubles. Of the total grains purchased by our grain marketing operations, 744 million bushels were from our individual and cooperative association members, 346 million bushels were from our country operations business and the remainder was from third parties.

Sales and Marketing; Customers

Purchasers of our grain and oilseed include domestic and foreign millers, maltsters, feeders, crushers and other processors. To a much lesser extent, purchasers include intermediaries and distributors. Our grain marketing operations are not dependent on any one customer, and its supply relationships call for delivery of grain at prevailing market prices.

Industry; Competition

Regulation.   Our grain marketing operations are subject to laws and related regulations and rules designed to protect the environment that are administered by the EPA, the DOT and similar government agencies. These laws, regulations and rules govern the discharge of materials into the environment, air and water; reporting storage of hazardous wastes and other hazardous materials; the transportation, handling and disposal of wastes and other materials; the labeling of pesticides and similar substances; and investigation and remediation of releases of hazardous materials. In addition, environmental laws impose a liability on owners and operators for investigation and remediation of contaminated property, and a party who sends hazardous materials to such site for treatment, storage, disposal or recycling. In some instances, such liability exists regardless of fault. Our grain marketing operations are also subject to laws and related regulations and rules administered by the USDA, the FDA, and other federal, state, local and foreign governmental agencies that govern the processing, packaging, storage, distribution, advertising, labeling, quality and safety of food and grain products. Failure to comply with these laws, regulations and rules could subject us to administrative penalties, injunctive relief, civil remedies and possible recalls of products. Our hedging transactions and activities are subject to the rules and regulations of the exchanges we use, including the CME, as well as the CFTC.

Competition.   Our grain marketing operations compete for both the purchase and the sale of grain. Competition is intense and margins are low. Some competitors are integrated food producers, which may also be customers. A few major competitors have substantially greater financial resources than us.

In the purchase of grain from producers, location of a delivery facility is a prime consideration, but producers are increasingly willing to transport grain longer distances for sale. Price is affected by the capabilities of the facility; for example, if it is cheaper to deliver to a customer by unit train than by truck, a facility with unit train capabilities provides a price advantage. We believe that our relationships with individual members serviced by our local country operations locations and with our cooperative members give us a broad origination capability.

Our grain marketing operations compete for grain sales based on price, services and ability to provide the desired quantity and quality of grains. Location of facilities is a major factor in the ability to compete. Our grain marketing operations

compete with numerous grain merchandisers, including major grain merchandising companies such as Archer Daniels Midland ("ADM"), Cargill, Incorporated ("Cargill") and Bunge as well as others, each of which handles significant grain volumes.

The results of our grain marketing operations may be adversely affected by relative levels of supply and demand, both domestic and international, commodity price levels (including grain prices reported on national markets) and transportation costs and conditions. Supply is affected by weather conditions, disease, insect damage, acreage planted and government regulations and policies. Demand may be affected by foreign governments and their programs, relationships of foreign countries with the United States, the affluence of foreign countries, acts of war, currency exchange fluctuations and substitution of commodities. Demand may also be affected by changes in eating habits, population growth, the level of per capita consumption of some products and the level of renewable fuels production.

Country Operations

Overview

Our country operations business purchases a variety of grains from our producer members and other third parties, and provides producer members and other customers with access to a full range of products, programs and services for production agriculture. Country operations operates 475 agri-operations locations through 73 business units dispersed throughout Colorado, Idaho, Illinois, Iowa, Kansas, Michigan, Minnesota, Montana, Nebraska, North Dakota, Oklahoma, Oregon, South Dakota, Texas, Washington, Wisconsin, and Canada. Most of these locations purchase grain from farmers and sell agronomy, energy, feed and seed products to those same producers and others, although not all locations provide every product and service.

Products and Services

Grain Purchasing.   We are one of the largest country elevator operators in North America based on revenues. Through a majority of our locations, our country operations business units purchase grain from member and non-member producers and other elevators and grain dealers. Most of the grain purchased is sold through our grain marketing operations, used for livestock feed production or sold to other processing companies. For the year ended August 31, 2015, country operations purchased approximately 604 million bushels of grain, primarily wheat, corn and soybeans. Of these bushels, 573 million were purchased from members and 346 million were sold through our grain marketing operations.

Other Products.   Our country operations business units manufacture and sell other products, both directly and through ownership interests in other entities. These include seed, crop nutrients, crop protection products, energy products, animal feed, animal health products and processed sunflower products.

Industry; Competition

Regulation.   Our country operations business is subject to laws and related regulations and rules designed to protect the environment that are administered by the EPA, the DOT and similar government agencies. These laws, regulations and rules govern the discharge of materials into the environment, air and water; reporting storage of hazardous wastes and other hazardous materials; the transportation, handling and disposal of wastes and other materials; the labeling of pesticides and similar substances; and the investigation and remediation of releases of hazardous materials. In addition, environmental laws impose a liability on owners and operators for investigation and remediation of contaminated property, and a party who sends hazardous materials to such site for treatment, storage, disposal or recycling. In some instances, such liability exists regardless of fault. Our country operations business is also subject to laws and related regulations and rules administered by the United States Department of Agriculture ("USDA"), the United States Food and Drug Administration ("FDA"), and other federal, state, local and foreign governmental agencies that govern the processing, packaging, storage, distribution, advertising, labeling, quality and safety of feed and grain products. Failure to comply with these laws, regulations and rules could subject us to administrative penalties, injunctive relief, civil remedies and possible recalls of products. Our hedging transactions and activities are subject to the rules and regulations of the exchanges we use, including the CME, as well as the CFTC.

Competition.   We compete primarily on the basis of price, services and patronage. Competitors for the purchase of grain include ADM, Cargill and similar corporations as well as local cooperatives, private grain companies and processors at the majority of our locations in the trade territories in which we operate.

Competitors for our farm supply and feed business include Cargill, ADM, and Land O' Lakes as well as local cooperatives and smaller private companies at the majority of locations throughout our trade territory.

Crop Nutrients

Overview

We believe our North American wholesale crop nutrients business is one of the largest wholesale fertilizer businesses in the U.S. based on tons sold. Tons sold include sales to our country operations retail business. There is significant seasonality in the sale of agronomy products and services, with peak activity coinciding with the planting seasons. There is also significant volatility in the prices for the crop nutrient products we purchase and sell.

In August 2015, we entered into an agreement with CF Industries Holdings, Inc. ("CF Industries") to invest $2.8 billion in cash in exchange for an 11.4% membership interest (based on product tons) in CF Industries Nitrogen LLC ("CF Nitrogen") and a separate supply agreement to purchase nitrogen fertilizer products from that entity over an 80-year term. The closing date for our investment in CF Nitrogen is anticipated to be February 1, 2016.

Operations

Products are delivered directly to the customer from the manufacturer or through our 22 inland or river warehouse terminals and other non-owned storage facilities located throughout the United States. To supplement what is purchased domestically, our Galveston, Texas deep water port and terminal receives fertilizer by vessel from origins such as Asia and the Caribbean basin where significant volumes of urea are produced. The fertilizer is then shipped by rail to destinations within crop producing regions of the country.

Primary suppliers for our wholesale crop nutrients business include CF Industries, HELM, Potash Corporation of Saskatchewan, Mosaic Company, Koch Industries and Petrochemical Industries Company ("PIC") in Kuwait.

Products and Services

Our wholesale crop nutrients business purchases and sells nitrogen (ammonia, Urea Ammonia Nitrate solution ("UAN") and Urea), phosphate and potash based products.

Sales and Marketing; Customers

Our wholesale crop nutrients business sells to local retailers from New York to the west coast and from Canada to Texas. Our largest customer is our own country operations business, which is also included in our Ag segment. Many of the customers of our crop nutrients business are also customers of our Energy segment or suppliers to our grain marketing business.

Industry; Competition

Regulation.   Our wholesale crop nutrients operations are subject to laws and related regulations and rules designed to protect the environment that are administered by the EPA, the DOT and similar government agencies. These laws, regulations and rules govern the discharge of materials into the environment, air and water; reporting storage of hazardous wastes and other hazardous materials; the transportation, handling and disposal of wastes and other materials; the labeling of pesticides and similar substances; and investigation and remediation of releases of hazardous materials. Failure to comply with these laws, regulations and rules could subject us to administrative penalties, injunctive relief, civil remedies and possible recalls of products. In addition, environmental laws impose a liability on owners and operators for investigation and remediation of contaminated property, and a party who sends hazardous materials to such site for treatment, storage, disposal or recycling. In some instances, such liability exists regardless of fault.

Competition.   The wholesale distribution of crop nutrients products is highly competitive and dependent upon relationships with local cooperatives and private retailers, proximity to the customer and competitive pricing. We compete with other large agronomy distributors, as well as other regional or local distributors, retailers and manufacturers. Major competitors in crop nutrients distribution include Agrium, CF Industries, Gavilon, Koch Industries, and a variety of traders and brokers.

Processing and Food Ingredients

Overview

Our processing and food ingredients business operates globally and converts oilseeds into meal, soyflour, edible oils, and associated by-products. We then further process soyflour for use in the food/snack industry. In July 2015, we purchased a canola processing facility in Hallock, Minnesota that produces canola oil and canola meal.

Operations

Our oilseed processing operations are conducted at facilities in Mankato, Minnesota; Fairmont, Minnesota; Creston, Iowa; Hallock, Minnesota; and Ashdod, Israel that can crush approximately 127 million bushels of oilseeds on an annual basis, producing approximately 2.8 million short tons of meal/flour and 1.6 billion pounds of edible oil. We also have operations in Hutchinson, Kansas; Ningbo, China; and South Sioux City, Nebraska where we further process soyflour for use in the food/snack industry.

Products and Services

Our oilseed processing operations produce three primary products: refined oils, soybean meal and soyflour. Refined oils are used in processed foods, such as margarine, shortening, salad dressings and baked goods, as well as methyl ester/biodiesel production, and to a lesser extent, for certain industrial uses such as plastics, inks and paints. Soybean meal has high protein content and is used for feeding livestock. Soyflour is used in the baking industry, as a milk replacement in animal feed and in industrial applications. Soyflour is processed further to produce textured concentrates and isolates used in the food/snack industry.

Our domestic oilseed processing facilities are located in areas with a strong production base of oilseeds and end-user market for the meal and soyflour. We purchase our oilseeds from members, global offices and third parties with tightly integrated connections with our grain marketing and country operations divisions. Our crushing operations currently produce approximately 95% of the edible oil that is refined, and purchase the balance from outside suppliers.

Soybeans and canola seeds are commodities and their price can fluctuate significantly depending on production levels, demand for the products and other supply factors.

Sales and Marketing; Customers

Our customers for edible oils are principally large food product companies including Ventura Foods, LLC ("Ventura Foods"), in which we hold a 50% ownership interest and with which we have a long-term supply agreement to supply edible oils as long as we maintain a minimum 25.5% ownership interest and our price is competitive with other suppliers of the product. We primarily sell meal to integrated livestock producers and feed mills and flour to customers in the food ingredient industry.

Industry; Competition

The refined oilseed industries are highly competitive. Major industry competitors include ADM, Cargill, Ag Processing Inc. and Bunge. These and other competitors have acquired other processors, expanded existing plants or constructed new plants, both domestically and internationally. Price, transportation costs, services and product quality drive competition. We are a relatively small participant in the protein food industry.

Regulation.   Our processing and food ingredients operations are subject to laws and related regulations and rules designed to protect the environment that are administered by the EPA, the DOT and similar government agencies. These laws, regulations and rules govern the discharge of materials into the environment, air and water; reporting storage of hazardous wastes and other hazardous materials; the transportation, handling and disposal of wastes and other materials; the labeling of pesticides and similar substances; and investigation and remediation of releases of hazardous materials. In addition, environmental laws impose a liability on owners and operators for investigation and remediation of contaminated property, and a party who sends hazardous materials to such sites for treatment, storage, disposal or recycling. In some instances, such liability exists regardless of fault. Our processing and food ingredients operations are also subject to laws and related regulations and rules administered by the USDA, the FDA, and other federal, state, local and foreign governmental agencies that govern the processing, packaging, storage, distribution, advertising, labeling, quality and safety of food and grain products. Failure to comply with these laws, regulations and rules could subject us, or our foods partners, to administrative penalties,

injunctive relief, civil remedies and possible recalls of products. Our hedging transactions and activities are subject to the rules and regulations of the exchanges we use, including the CME, as well as the CFTC.

Renewable Fuels

Overview

Our renewable fuels business produces ethanol and dried distillers grains with solubles ("DDGS"). We also market and distribute these products throughout the United States and overseas for our plants and other production plants.

Operations

We own and operate two ethanol plants in Rochelle, and Annawan, Illinois. These plants produce 250 million gallons of fuel grade ethanol and 650 thousand tons of DDGS annually. We also market over 500 million gallons of ethanol and 3.5 million tons of DDGS annually under marketing agreements for other production plants.

Products and Services

Our renewable fuels operations produce two primary products: Ethanol and DDGS. Ethanol is blended into gasoline. DDGS have a high protein content and are used for feeding livestock.

Sales and Marketing; Customers

Our renewable fuels business sells its production of ethanol and distillers grains throughout the United States and various international locations. We market renewable fuels to energy customers across the U.S. and through our Cenex- branded retail petroleum outlets and Cenex® convenience stores, and market DDGS globally on behalf of more than 20 ethanol plants across the United States. 

Industry; Competition

Regulation. Our renewable fuels operations are subject to laws, regulations and rules designed to protect the environment that are administered by the EPA, the DOT and similar government agencies. These laws, regulations and rules govern the discharge of materials into the environment, air and water; reporting storage of hazardous wastes and other hazardous materials; the transportation, handling and disposition of wastes and other materials; the labeling of pesticides and similar substances; and investigation and remediation of releases of hazardous materials. In addition, environmental laws impose a liability on owners and operators for investigation and remediation of contaminated property, and a party who sends hazardous materials to such site for treatment, storage, disposal or recycling. In some instances, such liability exists regardless of fault. Our renewable fuels operations are also subject to laws, regulations and rules administered by the USDA, the FDA, and other federal, state, local and foreign governmental agencies that govern the processing, packaging, storage, distribution, advertising, labeling, quality and safety of food and grain products. Failure to comply with these laws, regulations and rules could subject us to administrative penalties, injunctive relief, civil remedies and possible recalls of products. Our hedging transactions and activities are subject to the rules and regulations of the exchanges we use, including the CME, as well as the CFTC.

Competition. Ethanol and DDGS are globally traded commodities and the industry is highly competitive. The U.S. ethanol market is highly diverse with over 200 ethanol plants with more than 60 owners. Competitiveness of the industry is driven by: locations of the ethanol plant in relation to local corn availability; market access/transportation costs to DDGS and Ethanol markets; global trade flows of DDGS and ethanol; price spread between gasoline and ethanol; and efficiency of plant operations.

CORPORATE AND OTHER

Business Solutions

Financial Services.   In the past year, we have provided open account financing to approximately 75 of our cooperative association members. These arrangements involve the discretionary extension of credit in the form of a clearing account for settlement of grain purchases and as a cash management tool.

PCC, a wholly-owned subsidiary of CHS Insurance, is a protected cell captive insurance entity used to provide alternative risk financing options for customers.

Wheat Milling

In January 2002, we formed a joint venture with Cargill named Horizon Milling, LLC ("Horizon Milling"), in which we held an ownership interest of 24%, with Cargill owning the remaining 76%. Horizon Milling was the largest U.S. wheat miller based on output volume, and we owned five mills that we leased to Horizon Milling. During fiscal 2007, we expanded this operation with the formation of Horizon Milling G.P. (24% CHS ownership with Cargill owning the remaining 76%), a joint venture that acquired a Canadian grain-based foodservice and industrial business, which includes two flour milling operations and two dry baking mixing facilities in Canada.

In our third quarter of fiscal 2014, we formed Ardent Mills, LLC ("Ardent Mills") the largest flour miller in the U.S., a joint venture with Cargill and ConAgra Foods, Inc., which combines the North American flour milling operations of the three parent companies, including assets from our existing joint venture milling operations Horizon Milling and Horizon Milling, ULC and CHS-owned mills, with CHS holding a 12% interest in Ardent Mills. Prior to closing, we contributed $32.8 million to Horizon Milling to pay off existing debt as a pre-condition to close. Upon closing, Ardent Mills was financed with funds from third-party borrowings, which did not require credit support from the owners. We received $121.2 million of cash proceeds distributed to us in proportion to our ownership interest, adjusted for deviations in specified working capital target amounts, and recognized a gain of $109.2 million, associated with this transaction. In connection with the closing, the parties also entered into various ancillary and non-compete agreements including, among other things, an agreement for us to supply Ardent Mills with certain wheat and durum products. As we hold one of the five board seats, we account for Ardent Mills as an equity method investment, and on August 31, 2015 , our investment was $196.8 million .

Foods

Our primary focus in the foods area is Ventura Foods, LLC ("Ventura Foods") which produces and distributes vegetable oil-based products such as margarine, salad dressing and other food products. Ventura Foods was created in 1996, and is owned 50% by us and 50% by Wilsey Foods, Inc., a majority owned subsidiary of MBK USA Holdings, Inc. We account for our Ventura Foods investment under the equity method of accounting, and on August 31, 2015 , our investment was $347.7 million .

Ventura Foods manufactures, packages, distributes and markets bulk margarine, salad dressings, mayonnaise, salad oils, syrups, soup bases and sauces, many of which utilize soybean oil as a primary ingredient. Approximately 35% of Ventura Foods' volume, based on sales, comes from products for which Ventura Foods owns the brand, and the remainder comes from products that it produces for third parties. A variety of Ventura Foods' product formulations and processes are proprietary to it or its customers. Ventura Foods is the largest manufacturer of margarine for the foodservice sector in the U.S. and is a major producer of many other products.

Ventura Foods currently has 12 manufacturing and distribution locations across the United States. Ventura Foods sources its raw materials, which consist primarily of soybean oil, canola oil, palm/coconut oil, peanut oil and other ingredients and supplies, from various national and overseas suppliers, including our oilseed processing operations. It sells the products it manufactures to third parties as a contract manufacturer, as well as directly to retailers, food distribution companies and large institutional food service companies. Ventura Foods sales are approximately 60% in foodservice and the remainder is split between retail and industrial customers who use edible oil products as ingredients in foods they manufacture for resale.

Ventura Foods competes with a variety of large companies in the food manufacturing industry. Major competitors include ADM, Cargill and Bunge and others in the food manufacturing industry.

PRICE RISK AND HEDGING

When we enter into a commodity purchase or sales commitment, we incur risks related to price changes and performance including delivery, quality, quantity and shipment period. In the event that market prices decrease, we are exposed to risk of loss in the market value of inventory and purchase contracts with a fixed or partially fixed price. Conversely, we are exposed to risk of loss on our fixed or partially fixed price sales contracts in the event that market prices increase.

Our use of hedging reduces the exposure to price volatility by protecting against adverse short-term price movements, but it also limits the benefits of favorable short-term price movements. To reduce the price risk associated with fixed price commitments, we generally enter into commodity derivative contracts, to the extent practical, to achieve a net commodity position within the formal position limits we have established and deemed prudent for each commodity. These contracts are primarily transacted on regulated commodity futures exchanges but may also include over-the-counter derivative instruments when deemed appropriate. For commodities where there is no liquid derivative contract, risk is managed through the use of forward sales contracts, other pricing arrangements and, to some extent, futures contracts in highly correlated commodities.

These contracts are economic hedges of price risk, but are not designated as hedging instruments for accounting purposes. The contracts are recorded on our Consolidated Balance Sheets at fair values based on quotes listed on regulated commodity exchanges or the market prices of the underlying products listed on the exchanges. Fertilizer and propane contracts are accounted for as normal purchase and normal sales transactions. Unrealized gains and losses on these contracts are recognized in cost of goods sold in our Consolidated Statements of Operations.

When a futures position is established, initial margin must be deposited with the applicable exchange or broker. The amount of margin required varies by commodity and is set by the applicable exchange at its sole discretion. If the market price relative to a short futures position increases, an additional margin deposit would be required. Similarly, a margin deposit would be required if the market price relative to a long futures position decreases. Conversely, if the market price increases relative to a long futures position or decreases relative to a short futures position, margin deposits may be returned by the applicable exchange or broker.

Our policy is to maintain hedged positions in grains and oilseeds. Our profitability from operations is primarily derived from margins on products sold and grain merchandised, not from hedging transactions. At any one time, inventory and purchase contracts for delivery to us may be substantial. We have risk management policies and procedures that include established net position limits. These limits are defined for each commodity and include both trader and management limits. This policy and computerized procedures in our grain marketing operations require a review by operations management when any trader is outside of position limits and also a review by our senior management if operating areas are outside of position limits. A similar process is used in our energy and wholesale crop nutrients operations. The position limits are reviewed, at least annually, with our management and Board of Directors. We monitor current market conditions and may expand or reduce our net position limits or procedures in response to changes in those conditions. In addition, all purchase and sales contracts are subject to credit approvals and appropriate terms and conditions.

Use of hedging does not protect against nonperformance by counterparties to contracts. We primarily use exchange traded instruments that clear through a designated clearing organization which stands between us and the counterparty to minimize our counterparty exposure. We evaluate exposure by reviewing contracts and adjusting the values to reflect potential nonperformance. Risk of nonperformance by counterparties includes the inability to perform because of a counterparty's financial condition and the risk that the counterparty will refuse to perform on a contract during periods of price fluctuations where contract prices are significantly different than the current market prices. We manage our risks by entering into fixed price purchase and sales contracts with preapproved producers and by establishing appropriate limits for individual suppliers. Fixed price contracts are entered into with customers of acceptable creditworthiness, as internally evaluated. Historically, we have not experienced significant events of nonperformance on open contracts. Accordingly, we only adjust the estimated fair values of specifically identified contracts for nonperformance. Although we have established policies and procedures, we make no assurances that historical nonperformance experience will carry forward to future periods.

EMPLOYEES

On August 31, 2015, we had 12,511 full, part-time, temporary and seasonal employees, which included 708 employees of CHS McPherson (formerly known as NCRA). Of that total, 3,035 were employed in our Energy segment, 6,327 in our

country operations business (including approximately 1,478 seasonal and temporary employees), 227 in our crop nutrients operations, 1,243 in our grain marketing operations, 846 in our processing and food ingredients operations, 154 in our renewable fuels operations and 679 in Corporate and Other. In addition to those employed directly by us, many employees work for joint ventures in which we have a 50% or less ownership interest, and are not included in these totals.

Employees in certain areas are represented by collective bargaining agreements. Refinery and pipeline workers in Laurel, Montana are represented by agreements with two separate unions: the United Steel Worker ("USW") Union Local 11- 443 represents 219 refinery employees for which agreements are in place through January 31, 2019 and the Oil Basin Pipeliners Union ("OBP") represents 20 pipeline employees for which they have an evergreen labor agreement that renews every September 1, unless 60 days' notice is given. The contract covering the McPherson, Kansas refinery includes 335 employees represented by the United Steel Workers of America ("USWA") that is in place through June 2019. There are currently 82 employees in transportation and lubricant plant operations covered by collective bargaining agreements with the Teamsters that expire at various times, including a labor contract with Montana drivers which represents 21 employees, one with Wisconsin drivers representing 26 employees and one with lubricant plant production workers representing 35 employees.

Certain production workers in our processing and food ingredients operations are subject to collective bargaining agreements with the Bakery, Confectionary, Tobacco Worker and Grain Millers ("BCTGM") representing 122 employees, which expires on June 30, 2017 and the Pipefitters' Union representing 2 employees, which expires on April 30, 2016. The BTWGM also represents 40 employees at our Superior, Wisconsin grain export terminal with a contract expiring on June 30, 2016.

Various union contracts cover employees in other grain and crop nutrient terminal operations including: the USWA represents 90 employees at our Myrtle Grove, Louisiana grain export terminal with a contract expiring on May 31, 2016 and Teamsters represents 7 employees at our Winona, Minnesota river terminal with a contract expiring on February 28, 2019. Finally, certain employees in our country operations business are represented by two collective bargaining agreements. One with the BTWGM which represents 32 employees in two locations, Hermiston, Oregon and Great Falls, Montana, with contracts expiring on December 31, 2017 and June 30, 2018, respectively. The second with the Grain and General Services Union ("ILWU-Canada") which represents 4 employees located at Edenwold, SK, Canada.

CHS GOVERNANCE AND AUTHORIZED CAPITAL

Introduction

We are an agricultural membership cooperative organized under Minnesota cooperative law to do business with member and non-member patrons. Our patrons, not us, are subject to income taxes on income from patronage sources, which is distributed to them as qualified patronage. We are subject to income taxes on undistributed patronage income, non-qualified patronage distributions and non-patronage-sourced income. See "- Tax Treatment" below.

Distribution of Net Income; Patronage Dividends

We are required by our organizational documents to annually distribute net earnings derived from patronage business with members to members on the basis of patronage, except that the Board of Directors may elect to retain and add to our unallocated capital reserve an amount not to exceed 10% of the distributable net income from patronage business. We may also distribute net income derived from patronage business with a non-member if we have agreed to conduct business with the non-member on a patronage basis. Net income from non-patronage business may be distributed to members or added to the unallocated capital reserve, in whatever proportions the Board of Directors deems appropriate.

Accordingly, patronage refunds are calculated based on amounts using financial statement earnings. The cash portion of the patronage distribution is determined annually by the Board of Directors, with the balance issued in the form of qualified and non-qualified capital equity certificates. Consenting patrons have agreed to take both the cash and qualified capital equity certificate portion allocated to them from our previous fiscal year's income into their taxable income, and as a result, we are allowed a deduction from our taxable income for both the cash distribution and the allocated qualified capital equity certificates, as long as the cash distribution is at least 20% of the total patronage distribution. For the years ended August 31, 2014 and August 31, 2013 , 10% of earnings from patronage business was added to our capital reserves and the remaining 90% was primarily distributed during the second fiscal quarters of the years ended August 31, 2015 and August 31, 2014 , totaling $821.5 million and $841.1 million , respectively. The cash portion of the qualified distributions was deemed by the Board of Directors to be 40% for fiscal 2014 and 2013. Cash related to these distributions was $271.2 million and $286.8 million and

was paid during the years ended August 31, 2015 and August 31, 2014 , respectively. During the year ended August 31, 2013 , we distributed patronage refunds of $976.0 million , of which the cash portion was $380.9 million .

Patrons' Equities

Patrons' equities are in the form of book entries and represent a right to receive cash or other property when we redeem them. Patrons' equities form part of our capital, do not bear interest, and are not subject to redemption upon request of a patron. Patrons' equities are redeemable only at the discretion of the Board of Directors and in accordance with the terms of the redemption policy adopted by the Board of Directors, which may be modified at any time without member consent. Redemptions of capital equity certificates approved by the Board of Directors are divided into two pools, one for non-individuals (primarily member cooperatives) who may participate in an annual program for qualified equities held by them and another for individuals who are eligible for qualified equity redemptions at age 70 or upon death. In accordance with authorization from the Board of Directors, we expect total redemptions related to the year ended August 31, 2015 , that will be distributed in fiscal 2016, to be approximately $107.3 million .

Cash redemptions of qualified patrons' and other equities during the years ended August 31, 2015 , 2014 and 2013 were $128.9 million , $99.6 million and $193.4 million , respectively. Additionally, in fiscal 2014, we redeemed $200.0 million of patrons' equities by issuing 6,752,188 shares of Class B Series 1 Preferred Stock in exchange for members' equity certificates.

Governance

We are managed by a Board of Directors of not less than 17 persons elected by the members at our annual meeting. Terms of directors are staggered so that no more than seven directors are elected in any year. Our articles of incorporation and bylaws may be amended only upon approval of a majority of the votes cast at an annual or special meeting of our members, except for the higher vote described under "- Certain Antitakeover Measures" below.

Membership

We have two types of members, individuals and cooperative associations involved in agricultural production. As a membership cooperative, we do not have common stock. We may issue equity or debt instruments, on a patronage basis or otherwise, to our members.

Voting Rights

Voting rights arise by virtue of active membership in CHS, not because of ownership of any equity or debt instruments. Members that are cooperative associations that have met a minimum volume of business threshold with us during the previous fiscal year are entitled to vote based upon a formula that takes into account the equity held by the cooperative in CHS and the average amount of business done with us over the previous three years.

Members who are individuals that have done business with us during the previous fiscal year are entitled to one vote each. Individual members may exercise their voting power directly or through patrons' associations affiliated with a grain elevator, feed mill, seed plant or any other of our facilities (with certain historical exceptions) recognized by our Board of Directors. The number of votes of patrons' associations is determined under the same formula as cooperative association members.

Most matters submitted to a vote of the members require the approval of a majority of the votes cast at a meeting of the members, although certain actions require a greater vote. See "- Certain Antitakeover Measures" below.

Holders of our 8% Cumulative Redeemable Preferred Stock do not have voting rights, except as required by applicable law; provided, that the affirmative vote of two-thirds of the outstanding 8% Cumulative Redeemable Preferred Stock will be required to approve (i) any amendment to our articles of incorporation or the resolutions establishing the terms of our 8% Cumulative Redeemable Preferred Stock if the amendment adversely affects the rights or preferences of our 8% Cumulative Redeemable Preferred Stock or (ii) the creation of any class or series of equity securities having rights senior to our 8% Cumulative Redeemable Preferred Stock as to the payment of dividends or distribution of assets upon our liquidation, dissolution or winding up.

Holders of our Class B Preferred Stock do not have voting rights, except as required by applicable law; provided, that the affirmative vote of a majority of the outstanding shares of Class B Preferred Stock, voting as a class, will be required to approve (i) any amendment to our articles of incorporation or the resolutions establishing the terms of the Class B Preferred Stock, if the amendment adversely affects the powers, rights or preferences of the holders of the Class B Preferred Stock; or (ii) the creation of any class or series of capital stock, equity capital or patrons' equities having rights senior to our Class B Preferred Stock, as to the payment of dividends or distribution of assets upon our liquidation, dissolution or winding up. In addition, the holders of our Class B Series 2 Preferred Stock, our Class B Series 3 Preferred Stock and our Class B Series 4 Preferred Stock each vote separately as a series in respect of amendments solely relating to such series of our Class B Preferred Stock and adversely affecting the holders thereof.

Debt and Equity Instruments

We may issue debt and equity instruments to our current members and patrons, on a patronage basis or otherwise, and to persons who are neither members nor patrons. All equity we issue is subject to a first lien in favor of us for all indebtedness of the holder to us. On August 31, 2015 , our outstanding capital includes patrons' equities (consisting of qualified and non-qualified Capital Equity Certificates and Non-patronage Equity Certificates), preferred stock and certain capital reserves.

Dividends, which may be cumulative, may be paid on equity capital of CHS that is established in accordance with our articles of incorporation, provided that dividends on such equity capital may not exceed eight percent (8%) per annum. Unless otherwise expressly authorized by our Board of Directors, preferred stock established and issued pursuant to our articles of incorporation may only be sold or transferred with the approval of our Board of Directors. All of our preferred stock is listed and traded on the NASDAQ Global Select Market as expressly authorized by our Board of Directors.

Distribution of Assets upon Dissolution; Merger and Consolidation

In the event of our dissolution, liquidation or winding up, whether voluntary or involuntary, all of our debts and liabilities would be paid first according to their respective priorities. After such payment, the holders of each share of our preferred stock and any other equity securities would then be entitled to receive payment, out of available assets, in accordance with their respective liquidation preferences. After such distribution to the holders of equity capital, any excess would be paid to patrons on the basis of their past patronage with us. Our bylaws provide for the allocation among our members and nonmember patrons of the consideration received in any merger or consolidation to which we are a party.

Certain Antitakeover Measures

Our governing documents may be amended upon the approval of a majority of the votes cast at an annual or special meeting. However, if our Board of Directors, in its sole discretion, declares that a proposed amendment to our governing documents involves or is related to a "hostile takeover," the amendment must be adopted by 80% of the total voting power of our members.

The approval of not less than two-thirds of the votes cast at a meeting is required to approve a "change of control" transaction which would include a merger, consolidation, liquidation, dissolution or sale of all or substantially all of our assets. If our Board of Directors determines that a proposed change of control transaction involves a hostile takeover, the 80% approval requirement applies. The term "hostile takeover" is not further defined in the Minnesota cooperative law or our governing documents.

Tax Treatment

Subchapter T of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"), sets forth rules for the tax treatment of cooperatives and applies to both cooperatives exempt from taxation under Section 521 of the Internal Revenue Code and to nonexempt corporations operating on a cooperative basis. We are a nonexempt cooperative.

As a cooperative, we are not taxed on qualified patronage (minimum cash distribution requirement of 20%) allocated to our patrons either in the form of equities or cash. Consequently, those amounts are taxed only at the patron level. However, the amounts of any allocated but undistributed patronage earnings (called non-qualified written notices of allocation) are taxable to us when allocated. Upon redemption of any non-qualified written notices of allocation, the amount is deductible to us and taxable to our patron.

Income derived by us from non-patronage sources is not entitled to the "single tax" benefit of Subchapter T and is taxed to us at corporate income tax rates.

Prior to September 2013, NCRA (now CHS McPherson) was not consolidated for tax purposes. On September 1, 2013, NCRA began to be consolidated for tax purposes when our ownership increased to greater than 80%.

ITEM 1A.     RISK FACTORS

CAUTIONARY STATEMENT FOR PURPOSES OF THE SAFE HARBOR PROVISIONS

OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

The information in this Annual Report on Form 10-K for the year ended August 31, 2015 , includes "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. In addition, CHS and its representatives and agents may from time to time make other written or oral forward-looking statements, including statements contained in its filings with the Securities and Exchange Commission and its reports to its members and securityholders. Forward-looking statements give our current expectations relating to our financial condition, results of operations, plans, objectives, future performance and business. Words and phrases such as "will likely result," "are expected to," "is anticipated," "estimate," "project," "plan," "intend," "believe" and similar expressions identify forward-looking statements. We wish to caution readers not to place undue reliance on any forward-looking statements, which speak only as of the date made.

Our forward-looking statements are based on assumptions that we have made in light of our experience in the industries in which we operate, as well as our perceptions of historical trends, current conditions, expected future developments and other factors we believe are appropriate under the circumstances. However, our forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements. This Cautionary Statement is for the purpose of qualifying for the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995 and is intended to be a readily available written document that contains factors which could cause results to differ materially from those projected in the forward-looking statements. The following matters, among others, may have a material adverse effect on our business, financial condition, liquidity, results of operations or prospects, financial or otherwise. Reference to this Cautionary Statement in the context of a forward-looking statement shall be deemed to be a statement that any one or more of the following factors may cause actual results to differ materially from those which might be projected, forecasted, estimated or budgeted by us in the forward-looking statement or statements.

The following factors are in addition to any other cautionary statements, written or oral, which may be made or referred to in connection with any particular forward-looking statement. The following review should not be construed as exhaustive.

Except as required by applicable law, we undertake no obligation to revise any forward-looking statements to reflect future events or circumstances.

Our revenues, results of operations and cash flows could be materially and adversely affected by changes in commodity prices, as well as global and domestic economic downturns and risks.

              Our revenues, results of operations and cash flows are affected by market prices for commodities such as crude oil, natural gas, ethanol, fertilizer, grain, oilseed, flour and crude and refined vegetable oils. Commodity prices generally are affected by a wide range of factors beyond our control, including weather, disease, insect damage, drought, the availability and adequacy of supply, government regulation and policies, and general political and economic conditions. We are also exposed to fluctuating commodity prices as the result of our inventories of commodities, typically grain, fertilizer and petroleum products, and purchase and sale contracts at fixed or partially fixed prices. At any time, our inventory levels and unfulfilled fixed or partially fixed price contract obligations may be substantial. We have processes in place to monitor exposures to these risks and engage in strategies to manage these risks. If these controls and strategies are not successful in mitigating our exposure to these fluctuations, we could be materially and adversely affected. In addition, we are exposed to the risk of nonperformance by counterparties to contracts. Risk of nonperformance by counterparties includes the inability to perform because of a counterparty's financial condition and liquidity and also the risk that the counterparty will refuse to perform a contract during a period of price fluctuations where contract prices are significantly different than the current market prices. Increases in market prices for commodities that we purchase without a corresponding increase in the prices of our products or our sales volume or a decrease in our other operating expenses could reduce our revenues and net income. In addition, the level of demand for our products is affected by global and regional demographics and macroeconomic conditions, including population growth rates and changes in standards of living. A significant downturn in global economic growth or recessionary conditions in major geographic regions, may lead to a reduced demand for agricultural commodities, which could have a material adverse effect on our business, financial condition, liquidity, results of operations and prospects. Additionally, weak global conditions and adverse conditions in global financial markets may adversely impact the financial condition and liquidity of some of our customers, suppliers and other counterparties, which could have a material adverse effect on our business, financial condition, liquidity, results of operations and prospects.

Our revenues originated outside of the U.S. were approximately 20% of consolidated net sales in fiscal 2015 and one of our core strategic initiatives includes global expansion. As a result, we are exposed to risks associated with having increased global operations outside the U.S., including economic or political instability in the international markets in which we do business, including South America, Europe and the Middle East, the Black Sea and Mediterranean Basin regions and the Asia Pacific region.

              In our energy operations, profitability depends largely on the margin between the cost of crude oil that we refine and the selling prices that we obtain for our refined products. The prices for both crude oil and for gasoline, diesel fuel and other refined petroleum products fluctuate widely. Factors influencing these prices, many of which are beyond our control, include:

              The long-term effects of these and other conditions on the prices of crude oil and refined petroleum products are uncertain and ever-changing. Increases in crude oil prices without a corresponding increase in the prices of our refined petroleum products, and decreases in crude oil prices with larger corresponding decreases in the prices of our refined petroleum products, would reduce our net income. Accordingly, we expect our margins on, and the profitability of our energy business to fluctuate, possibly significantly, over time.

Our revenues, results of operations and cash flows could be materially and adversely affected if our members were to do business with others rather than with us.

              We do not have an exclusive relationship with our members and our members are not obligated to supply us with their products or purchase products from us. Our members often have a variety of distribution outlets and product sources available to them. If our members were to sell their products to other purchasers or purchase products from other sellers, our revenues would decline and our results of operations and cash flows could be materially and adversely affected.

We participate in highly competitive business markets and we may not be able to continue to compete successfully, which would have a material adverse effect on us.

              We operate in several highly competitive business segments and our competitors may succeed in developing new or enhanced products that are better than ours, and may be more successful in marketing and selling their products than we are with ours. Competitive factors include price, service level, proximity to markets, product quality and marketing. In our business segments, we compete with certain companies that are larger, better known and have greater marketing, financial, personnel and other resources. As a result, we may not be able to continue to compete successfully with our competitors, which could have a material adverse effect on our business, financial condition, liquidity, results of operations and prospects.

Changes in federal income tax laws or in our tax status could increase our tax liability and reduce our net income significantly.

              Current federal income tax laws, regulations and interpretations regarding the taxation of cooperatives, which allow us to exclude income generated through business with or for a member (patronage income) from our taxable income, could be changed. If this occurred, or if in the future we were not eligible to be taxed as a cooperative, our tax liability would significantly increase and our net income would significantly decrease.

We incur significant costs in complying with applicable laws and regulations. Any failure to make the capital or other investments necessary to comply with these laws and regulations could expose us to unanticipated expenditures and liabilities.

              We are subject to numerous federal, state and local provisions regulating our business and operations, including those involving antitrust, intellectual property, environmental, and U.S. and foreign anti-bribery/anti-corruption or other matters. We incur and expect to incur significant capital and operating expenses to comply with these laws and regulations. We may be unable to pass on those expenses to customers without experiencing volume and margin losses.

              We establish reserves for the future cost of known compliance obligations, such as remediation of identified environmental issues. However, these reserves may prove inadequate to meet our actual liability. Moreover, amended, new or more stringent requirements, stricter interpretations of existing requirements or the future discovery of currently unknown compliance issues may require us to make material expenditures or subject us to liabilities that we currently do not anticipate. Furthermore, our failure to comply with applicable laws and regulations could subject us to administrative penalties and injunctive relief, civil remedies, including fines and injunctions, and recalls of our products. For example, we regularly maintain hedges to manage the price risks associated with our commercial operations. These transactions typically take place on exchanges such as the CME. Our hedging transactions and activities are subject to the rules and regulations of the exchanges we use, including the CME, as well as the CFTC. All exchanges have broad powers to review required records, investigate and enforce compliance and to punish noncompliance by entities subject to its jurisdiction. The failure to comply with such rules and regulations could lead to restrictions on our trading activities or subject us to enforcement action by the CFTC or a disciplinary action by the exchanges, which could lead to substantial sanctions.

In July 2013, CHS received a letter from the CFTC requesting CHS to preserve, and to produce to the CFTC on a voluntary basis, documents concerning CHS's trading positions, including futures hedging transactions on the CME, for the period from January 1, 2010 through June 30, 2013. CHS is complying with this request and continuing to cooperate with the CFTC's inquiry. CHS also received a letter from the CME in June 2013 advising that its market surveillance department was reviewing certain of CHS's futures positions in April and May of 2013 and requesting that CHS produce relevant documents for its review. CHS produced those documents and the CME closed its inquiry in December 2014. Any investigation or proceeding by the CME or the CFTC, whether successful or unsuccessful, could result in substantial costs, the diversion of resources, including management time, and potential harm to our reputation, all of which could have a material adverse effect on our business, financial condition, liquidity, results of operations and prospects.

We are subject to the Foreign Corrupt Practices Act of 1977, as amended, and other similar anti-corruption, anti-bribery and anti-kickback laws and regulations, and any noncompliance with those laws and regulations by us or others acting on our behalf could have a material adverse effect on our business, financial condition and results of operations.

We operate on a global basis and are subject to anti-corruption, anti-bribery and anti-kickback laws and regulations, including the Foreign Corrupt Practices Act of 1977, as amended (the "FCPA"). The FCPA and other similar anti-corruption, anti-bribery and anti-kickback laws and regulations in other jurisdictions generally prohibit companies and their intermediaries or agents from making improper payments to government officials or any other persons for the purpose of obtaining or retaining business. We operate and sell our products in many parts of the world that have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-corruption, anti-bribery and anti-kickback laws and regulations may conflict with local customs and practices. In addition, in certain countries, we engage third-party agents or intermediaries to act on our behalf. If these third parties violate applicable anti-corruption, anti-bribery or anti-kickback laws or regulations, we may be liable for those violations. We have policies in place prohibiting employees from making or authorizing improper payments, we train our employees regarding compliance with anti-corruption, anti-bribery and anti-kickback laws and regulations, and we utilize procedures to identify and mitigate risks of such misconduct by our employees or third party agents or intermediaries. However, we cannot provide assurances that our employees or third party agents or intermediaries will comply with those policies, laws and regulations. If we are found liable for violations of the FCPA, or other similar anti-corruption, anti-bribery or anti-kickback laws or regulations, either due to our own acts or out of inadvertence, or due to the acts or inadvertence of others, we could suffer criminal or civil fines or penalties or other repercussions, including reputational harm, which could have a material adverse effect on our business, financial condition and results of operations.

Changing environmental and energy laws and regulation, may result in increased operating costs and capital expenditures and may have a material and adverse effect on us.

              New environmental laws and regulations, including new regulations relating to alternative energy sources and the risk of global climate change, new interpretations of existing laws and regulations, increased governmental enforcement or other developments could require us to make additional unforeseen expenditures or to make unforeseen changes to our operations, either of which could adversely affect us.

              It is possible that some form of regulation will be forthcoming at the federal level in the United States with respect to emissions of greenhouse gases ("GHG"s) (including carbon dioxide, methane and nitrous oxides). Also, new federal or state legislation or regulatory programs that restrict emissions of GHGs in areas where we conduct business could adversely affect our operations and the demand for our energy products, which would have a material adverse effect on our business, financial condition, liquidity, results of operations and prospects. New legislation or regulator programs could require substantial expenditures for the installation and operation of systems and equipment that we do not currently possess or for substantial modifications to existing equipment. The actual effects of climate change on our businesses are, however, unknown and indeterminable at this time.

              Pursuant to the Energy Independence and Security Act of 2007, the EPA has promulgated the Renewable Fuel Standard ("RFS"), which requires refiners to blend renewable fuels, such as ethanol and biodiesel, with their petroleum fuels or purchase renewable energy credits, known as RINs, in lieu of blending. The EPA generally establishes new annual renewable fuel percentage standards for each compliance year in the preceding year. We generate RINs in our marketing operations under the RFS, however it is not enough to meet the needs of our refining capacity and RINs must be purchased on the open market. In recent years the price of RINs has been extremely volatile. As a result, the purchase of RINs could have a negative impact on our future refined fuels margins, the impact of which we are not able to estimate at this time.

Governmental policies and regulation affecting the agricultural sector and related industries could have a material adverse effect on us.

              The compliance burden and impact on our operations and profitability as a result of the enactment of the Dodd-Frank Wall Street Reform and Consumer Protection Act ("Dodd-Frank") and related regulations continue to evolve, as federal agencies are implementing its many provisions through regulation. These efforts to change the regulation of financial markets will subject users of derivatives, such as CHS, to extensive oversight and regulation by the CFTC. Such initiatives will impose significant additional costs on us, including operating and compliance costs, and could materially affect the availability, as well as the cost and terms, of certain transactions. Certain federal regulations, studies and reports addressing Dodd-Frank, including the regulation of swaps and derivatives, are still being implemented and others are being finalized. We will continue to monitor these developments. Any of these matters could have a material adverse effect on our business, financial condition, liquidity, results of operations and prospects.

Environmental liabilities could have a material adverse effect on us.

              Many of our current and former facilities have been in operation for many years and, over that time, we and other operators of those facilities have generated, used, stored and disposed of substances or wastes that are or might be considered hazardous under applicable environmental laws, including liquid fertilizers, chemicals and fuels stored in underground and above-ground tanks. Any past or future actions in violation of applicable environmental laws could subject us to administrative penalties, fines, other costs, such as capital expenditures, and injunctions. In addition, an owner or operator of contaminated property, and a party who sends hazardous materials to such site for treatment, storage, disposal or recycling, can be liable for the cost of investigation and remediation under environmental laws. In some instances, such liability exists regardless of fault. Moreover, future or unknown past releases of hazardous substances could subject us to private lawsuits claiming damages, including for bodily injury or property damage, and to adverse publicity, which could have a material adverse effect on us. Liabilities, including legal costs, related to remediation of contaminated properties are not recognized until the related costs are considered probable and can be reasonably estimated.

Actual or perceived quality, safety or health risks associated with our products could subject us to significant liability and damage our business and reputation.

              If any of our food or feed products became adulterated or misbranded, we would need to recall those items and could experience product liability claims if consumers or customers' livestock were injured as a result. A widespread product recall or a significant product liability judgment could cause our products to be unavailable for a period of time or could cause a loss of consumer confidence in our products. Even if a product liability claim is unsuccessful or is not fully pursued, the negative publicity surrounding any assertion that our products caused illness or injury could adversely affect our business and reputation with existing and potential customers and our corporate and brand image. Moreover, claims or liabilities of this sort might not be covered by our insurance or by any rights of indemnity or contribution that we may have against others. In addition, general public perceptions regarding the quality, safety or health risks associated with particular food or feed products, such as concerns regarding genetically modified crops, could reduce demand and prices for some of the products associated with our businesses. To the extent that consumer preferences evolve away from products that our members or we produce for health or other reasons, such as the growing demand for organic food products, and we are unable to develop or procure products that satisfy new consumer preferences, there will be a decreased demand for our products, which could have a material adverse effect on our business, financial condition, liquidity, results of operations and prospects.

Our financial results are susceptible to seasonality.

              Many of our business activities are highly seasonal and operating results vary throughout the year. Our income is generally lowest during the second fiscal quarter and highest during the third fiscal quarter. For example, in our Ag segment, our crop nutrients and country operations businesses generally experience higher volumes and income during the spring planting season and during the fall harvest season. Our grain marketing operations are also subject to fluctuations in volume and income based on producer harvests, world grain prices and demand. Our Energy segment generally experiences higher volumes and income in certain operating areas, such as refined products, in the summer and early fall when gasoline and diesel fuel usage is highest and is subject to global supply and demand forces. Other energy products, such as propane, may experience higher volumes and income during the winter heating and crop drying seasons.

Our operations are subject to business interruptions and casualty losses; we do not insure against all potential losses and could be seriously harmed by unanticipated liabilities.

              Our operations are subject to business interruptions due to unanticipated events such as explosions, fires, pipeline interruptions, transportation delays, equipment failures, crude oil or refined product spills, inclement weather and labor disputes. For example:

              The effects of any of these events could be significant. We maintain insurance coverage against many, but not all potential losses or liabilities arising from these operating hazards, but uninsured losses or losses above our coverage limits are possible. Uninsured losses and liabilities arising from operating hazards could have a material adverse effect on us.

Our cooperative structure limits our ability to access equity capital.

              As a cooperative, we may not sell common stock in our company. In addition, existing laws and our articles of incorporation and bylaws limit dividends on any preferred stock we may issue to 8% per annum. These limitations may restrict our ability to raise equity capital and may adversely affect our ability to compete with enterprises that do not face similar restrictions.

Consolidation among the producers of products we purchase and customers for products we sell could materially and adversely affect our revenues, results of operations and cash flows.

              Consolidation has occurred among the producers of products we purchase, including crude oil, fertilizer and grain, and it is likely to continue in the future. Consolidation could increase the price of these products and allow suppliers to negotiate pricing, supply availability and other contract terms that are less favorable to us. Consolidation also may increase the competition among consumers of these products to enter into supply relationships with a smaller number of producers, resulting in potentially higher prices for the products we purchase.

              Consolidation among purchasers of our products and in wholesale and retail distribution channels has resulted in a smaller customer base for our products and intensified the competition for these customers. For example, ongoing consolidation among distributors and brokers of food products and food retailers has altered the buying patterns of these businesses, as they have increasingly elected to work with product suppliers who can meet their needs nationwide rather than just regionally or locally. If these distributors, brokers and retailers elect not to purchase our products, our revenues, results of operations and cash flows could be materially and adversely affected.

              In the fertilizer market, consolidation at both the producer and customer level increases the potential for direct sales from the producer to the consumer.

If our customers choose alternatives to our refined petroleum products, our revenues, results of operations and cash flows could be materially and adversely affected.

              Numerous alternative energy sources currently under development could serve as alternatives to our gasoline, diesel fuel and other refined petroleum products. If any of these alternative products become more economically viable or preferable to our products for environmental or other reasons, demand for our energy products would decline. Demand for our gasoline, diesel fuel and other refined petroleum products also could be adversely affected by increased fuel efficiencies. Declining demand for our energy products could materially and adversely affect our revenues, results of operations and cash flows.

The results of our agronomy business are highly dependent upon certain factors outside of our control.

              Planted acreage, and consequently the volume of fertilizer and crop protection products applied, is partially dependent upon government programs, grain prices and the perception held by the producer of demand for production. Weather conditions during the spring planting season and early summer spraying season also affect agronomy product volumes and profitability. As a result, factors outside of our control could materially and adversely affect our revenues, results of operations and cash flows.

Technological improvements in agriculture could decrease the demand for our agronomy and energy products.

              Technological advances in agriculture could decrease the demand for crop nutrients, energy and other crop input products and services that we provide. Genetically engineered seeds that resist disease and insects, or that meet certain nutritional requirements, could affect the demand for our crop nutrients and crop protection products. Demand for fuel that we sell could decline as technology allows for more efficient usage of equipment. Declining demand for our products could materially and adversely affect our revenues, results of operations and cash flows.

We will require significant financing to consummate our strategic venture with CF Industries.

At the closing of our strategic venture with CF Industries, we will be required to pay $2.8 billion in cash to purchase a minority interest in CF Nitrogen. Currently, we expect to fund approximately $1.6 billion of this amount by incurring new additional indebtedness. There can be no assurance that market conditions will allow us to incur the additional debt required to consummate the strategic venture with CF Industries, including at favorable terms. If market conditions do not allow us to incur this new additional debt, and alternative financing sources are not available to us, the strategic venture with CF Industries may not be consummated.

Acquisitions, strategic alliances, joint ventures, divestitures, and other non-ordinary course of business events resulting from portfolio management actions and other evolving business strategies, including our strategic venture with CF Industries, could affect future results.

We monitor our business portfolio and organizational structure and have made and may continue to make acquisitions, strategic alliances, joint ventures, divestitures and changes to our organizational structure. With respect to acquisitions, future results will be affected by our ability to integrate acquired businesses quickly and obtain the anticipated synergies. Our ability to successfully complete a divestiture will depend on, among other things, our ability to identify buyers that are prepared to acquire such assets or businesses on acceptable terms and to adjust and optimize our retained businesses following the divestiture. Additionally, we may fail to consummate proposed acquisitions, divestitures, joint ventures or strategic alliances after incurring expenses and devoting substantial resources, including management time, to such transactions.

              Several parts of our business, including in particular, portions of our grain marketing, wheat milling and foods operations, are operated through joint ventures with third parties. By operating a business through a joint venture, we have less control over business decisions than we have in our wholly-owned or majority-owned businesses. In particular, we generally cannot act on major business initiatives in our joint ventures without the consent of the other party or parties in those ventures. Investments in joint ventures may, under certain circumstances, involve risks not present when a third party is not involved, including the possibility that co-venturers might become bankrupt or fail to fund their share of required capital contributions, in which case we and any other remaining co-venturers would generally be liable for the joint venture's liabilities. Co-venturers may have economic, tax or other business interests or goals which are inconsistent with our business interests or goals, and may be in a position to take actions contrary to our policies or objectives. Our co-venturers may take actions that are not within our control. Joint venture investments may also lead to impasses. Disputes between us and co-venturers may result in litigation or arbitration that would increase our expenses and prevent our officers and/or directors from focusing their time and effort on our day-to-day business. In addition, we may in certain circumstances be liable for the actions of our co-venturers. Each of these matters could have a material adverse effect on us.

In February 2016, we expect to close our strategic venture with CF Industries, pursuant to which, among other things, we will purchase a minority interest in CF Nitrogen for $2.8 billion in cash and enter into a supply agreement that will entitle us to purchase up to an aggregate of 1.7 million tons of granular urea and urea ammonium nitrate solution annually at market prices over an 80-year term. Although we currently expect that our strategic venture with CF Industries will close on February 1, 2016, there can be no assurance that the closing of this strategic venture will not be delayed, or that the closing of this strategic venture will actually occur.

We utilize information technology systems to support our business. An ongoing multi-year implementation of an enterprise-wide resource planning ("ERP") system, security breaches, or other disruptions to our information technology systems or assets could interfere with our operations, compromise security of our customers' or suppliers' information, and expose us to liability which could adversely impact our business and reputation.

Our operations rely on certain key information technology ("IT") systems, some of which are dependent upon third party services, to provide critical connections of data, information and services for internal and external users. Over the next several years, we expect to implement a new enterprise resource planning system ("ERP"), which has and will continue to require significant capital and human resources to deploy. There can be no assurance that the actual costs for the ERP will not exceed our current estimates or that the ERP will not take longer to implement than we currently expect. In addition, potential flaws in implementing the ERP may pose risks to our ability to operate successfully and efficiently. There may be other challenges and risks to our IT systems over time due to any number of causes, such as catastrophic events, power outages, security breaches or cyber-based attacks, and as we upgrade and standardize our ERP system on a worldwide basis. These challenges and risks could result in legal claims or proceedings, liability or penalties, disruption in operations, loss of valuable data, and damage to our reputation, which could adversely affect our business.

We also have offices in Eagan, Minnesota and Washington, D.C. which are leased.

ITEM 3.     LEGAL PROCEEDINGS

We are involved as a defendant in various lawsuits, claims and disputes, which are in the normal course of our business. The resolution of any such matters may affect consolidated net income for any fiscal period; however, our management believes any resulting liabilities, individually or in the aggregate, will not have a material effect on our consolidated financial position, results of operations or cash flows during any fiscal year.

Laurel

On August 30, 2012, we received from the EPA a request for information pursuant to Section 114 of the Clean Air Act. The information requested relates to operational information and design data for flares at our Laurel, Montana refinery for the period from January 1, 2006 to present. The information request could potentially result in an enforcement action by the EPA with respect to flare efficiency or other issues. We provided the requested information in December 2012 and are awaiting the EPA's response. As it is too early to determine the potential liability or extent of potential costs associated with any such action, we have not recorded a liability associated with this request. While the facts and circumstances of enforcement actions under the Clean Air Act relating to flares at refineries differ on a case-by-case basis, some refineries have incurred significant penalties and other costs in connection with such enforcement actions.

On September 18, 2015, we received a letter from the Montana Department of Environmental Quality (the "MDEQ") alleging that, from May 2013 through May 2015, sulfur dioxide emissions from one of the incinerator stacks at our Laurel, Montana refinery exceeded the amounts allowable under the refinery's permits, and requesting that we execute a consent order with the MDEQ providing, among other things, for our payment of an administrative penalty in the amount of $183,425. On October 16, 2015, we sent a response letter to the MDEQ, disputing certain factual matters set forth in MDEQ's original letter and requesting certain modifications to the proposed consent order, including a significant decrease in the amount of the proposed administrative penalty. We are awaiting the MDEQ's response to our letter.

ITEM 4.     MINE SAFETY DISCLOSURES

We have approximately 93,700 members, of which approximately 1,100 are cooperative association members and approximately 92,600 are individual members. As a cooperative, we do not have any common stock that is traded or otherwise.

The following table is a summary of our outstanding preferred stock as of August 31, 2015 , all of which are listed on the Global Select Market of NASDAQ:

We have not sold any equity securities during the three years ended August 31, 2015 that were not registered under the Securities Act of 1933, as amended.

ITEM 6.     SELECTED FINANCIAL DATA

The following table sets forth our selected historical consolidated financial information for each of the five periods indicated. This information should be read in conjunction with "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" and with our consolidated financial statements and notes thereto included elsewhere in this Annual Report on Form 10-K.

Our consolidated financial statements are prepared in accordance with U.S. GAAP. The selected financial information as of and for the years ended August 31, 2015, 2014, 2013, 2012 and 2011 is derived from our audited consolidated financial statements and related notes. We have revised certain prior period amounts in this table to include activity and amounts related to capital leases that were previously incorrectly accounted for as operating leases. See Note 18, Correction of Immaterial Errors , to our audited consolidated financial statements included in this Annual Report on Form 10-K for more information on the nature and amounts of these revisions.

Selected Consolidated Financial Data

ITEM 7.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

The following discussion of financial condition and results of operations should be read in conjunction with the accompanying audited financial statements and notes to such statements and the cautionary statement regarding forward-looking statements found in Part I, Item 1A of this Form 10-K. This discussion contains forward-looking statements based on current expectations, assumptions, estimates and projections of our management. Actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, as more fully described in the cautionary statement and elsewhere in this Form 10-K.

CHS Inc. ("CHS", "we" or "us") is a diversified company, which provides grain, foods and energy resources to businesses and consumers on a global basis. As a cooperative, we are owned by farmers, ranchers and their member cooperatives across the United States. We also have preferred stockholders that own shares of our 8% Cumulative Redeemable Preferred Stock ("8% Preferred Stock"), our Class B Cumulative Redeemable Preferred Stock, Series 1 ("Class B Series 1 Preferred Stock"), our Class B Reset Rate Cumulative Redeemable Preferred Stock, Series 2 ("Class B Series 2 Preferred Stock"), our Class B Reset Rate Cumulative Redeemable Preferred Stock, Series 3 ("Class B Series 3 Preferred Stock") and our Class B Cumulative Redeemable Preferred Stock, Series 4 ("Class B Series 4 Preferred Stock"), which are listed on the Global Select Market of the NASDAQ Stock Market LLC ("NASDAQ") under the symbols CHSCP, CHSCO, CHSCN, CHSCM and CHSCL, respectively.

We provide a full range of production agricultural inputs such as refined fuels, propane, farm supplies, animal nutrition and agronomy products, as well as services, which include hedging, financing and insurance services. We own and operate petroleum refineries and pipelines and market and distribute refined fuels and other energy products under the Cenex ® brand through a network of member cooperatives and independents. We purchase grains and oilseeds directly and indirectly from agricultural producers primarily in the midwestern and western United States. These grains and oilseeds are either sold to domestic and international customers or further processed into a variety of grain-based food products or renewable fuels.

The consolidated financial statements include the accounts of CHS and all of our wholly-owned and majority-owned subsidiaries and limited liability companies, including our McPherson, Kansas refinery in our Energy segment. The effects of all significant intercompany transactions have been eliminated.

Prior to fiscal 2015, our renewable fuels marketing business was included in our Energy segment and our renewable fuels production business was included in our Ag segment. At the beginning of fiscal 2015, we reconfigured certain parts of our business to better align our ethanol supply chain. As a result, our renewable fuels marketing business is now managed together with our renewable fuels production business within our Ag segment. In accordance with Accounting Standards Codification ("ASC") Topic 280, Segment Reporting , we have identified our operating segments to reflect the manner in which our chief operating decision maker evaluates performance and manages the business, and we have aggregated those operating segments into our reportable Energy and Ag segments. Prior period segment information has been revised to reflect this change to ensure comparability.

Our Energy segment produces and provides primarily for the wholesale distribution of petroleum products and transportation of those products. Our Ag segment purchases and further processes or resells grains and oilseeds originated by our country operations business, by our member cooperatives and by third parties, and also serves as a wholesaler and retailer of crop inputs. Corporate and Other primarily represents our non-consolidated wheat milling and packaged food joint ventures, as well as our business solutions operations, which consist of commodities hedging, insurance and financial services related to crop production.

Corporate administrative expenses and interest are allocated to each business segment, and Corporate and Other, based on direct usage for services that can be tracked, such as information technology and legal, and other factors or considerations relevant to the costs incurred.

Many of our business activities are highly seasonal and operating results vary throughout the year. Our income is generally lowest during the second fiscal quarter and highest during the third fiscal quarter. For example, in our Ag segment, our crop nutrients and country operations businesses generally experience higher volumes and income during the spring planting season and in the fall, which corresponds to harvest. Our grain marketing operations are also subject to fluctuations in volume and earnings based on producer harvests, world grain prices and demand. Our Energy segment generally experiences higher volumes and profitability in certain operating areas, such as refined products, in the summer and early fall when gasoline and diesel fuel usage is highest and is subject to global supply and demand forces. Other energy products, such as propane, may experience higher volumes and profitability during the winter heating and crop drying seasons.

Our revenues, assets and cash flows can be significantly affected by global market prices for commodities such as petroleum products, natural gas, grains, oilseeds, crop nutrients and flour. Changes in market prices for commodities that we purchase without a corresponding change in the selling prices of those products can affect revenues and operating earnings. Commodity prices are affected by a wide range of factors beyond our control, including the weather, crop damage due to disease or insects, drought, the availability and adequacy of supply, government regulations and policies, world events, and general political and economic conditions.

While our revenues and operating results are derived from businesses and operations which are wholly-owned and majority-owned, a portion of our business operations are conducted through companies in which we hold ownership interests of

50% or less and do not control the operations. We account for these investments primarily using the equity method of accounting, wherein we record our proportionate share of income or loss reported by the entity as equity income from investments, without consolidating the revenues and expenses of the entity in our Consolidated Statements of Operations. In our Ag segment, this principally includes our 50% ownership in TEMCO. In Corporate and Other, these investments principally include our 50% ownership in Ventura Foods and our 12% ownership in Ardent Mills.

Recent Events

In August 2015, after evaluating the feasibility of constructing and operating the previously proposed nitrogen fertilizer manufacturing plant in Spiritwood, North Dakota, we determined not to move forward with the construction of that facility. As a result, we recorded impairment and exit charges of $116.5 million within marketing, general and administrative expense in our Consolidated Statement of Operations for the year ended August 31, 2015.

In August 2015, we entered into an agreement with CF Industries Holdings, Inc. ("CF Industries") to invest $2.8 billion in cash in exchange for an 11.4% membership interest (based on product tons) in CF Industries Nitrogen LLC ("CF Nitrogen") and a separate supply agreement to purchase nitrogen fertilizer products from that entity over an 80-year term. The closing date for our investment in CF Nitrogen is anticipated to be February 1, 2016.

General .  We recorded income before income taxes of $768.2 million during the year ended August 31, 2015, compared to $1,131.3 million recorded during the year ended August 31, 2014, a decrease of $363.1 million (32%). Results reflect decreased pretax earnings in our Energy and Ag segments, as well as Corporate and Other. The results reflect an impairment in fiscal 2015 associated with our exit of our Spiritwood project of approximately $116.5 million, as a well as a gain associated with the formation of Ardent Mills of $109.2 million in fiscal 2014 which did not reoccur in fiscal 2015.

Our Energy segment generated income before income taxes of $538.1 million for the year ended August 31, 2015 compared to $728.4 million for the year ended August 31, 2014, representing a decrease of $190.3 million (26%), primarily due to significantly reduced refining margins in fiscal 2015 as a result of the turnaround at our McPherson refinery in the third quarter of fiscal 2015 and the turnaround at our Laurel, Montana refinery in the fourth quarter of fiscal 2015. We are subject to the Renewable Fuel Standard ("RFS") which requires refiners to blend renewable fuels (e.g., ethanol, biodiesel) into their finished transportation fuels or purchase renewable energy credits, known as Renewable Identification Numbers ("RIN"s), in lieu of blending. The EPA generally establishes new annual renewable fuel percentage standards for each compliance year in the preceding year, although the EPA did not release the proposed mandate for 2014 or 2015 until May 2015. We generate RINs under the RFS in our renewable fuels operations and through our blending activities at our terminals, however we cannot generate enough RINs to meet the needs of our refining capacity and RINs must be purchased on the open market. The price of RINs can be extremely volatile when refiners await an EPA adjustment to the mandate. As mentioned above, in May 2015, the EPA released the proposed mandate for years 2014 and 2015, as well as 2016, which resulted in a decline in the price of RINs. A significant change in the price of RINs could have a material impact on our results of operations in the future.

Our Ag segment generated income before income taxes of $149.6 million for the year ended August 31, 2015, compared to $213.4 million in the year ended August 31, 2014, a decrease in earnings of $63.8 million (30%). The decrease in our Ag segment results was primarily driven by an impairment charge of $116.5 million which was recorded in fiscal 2015 and was associated with our decision to cease development of our planned nitrogen fertilizer plant in Spiritwood, North Dakota. Our grain marketing earnings decreased $44.1 million during the year ended August 31, 2015 compared with the prior year, primarily as a result of robust logistical performance in fiscal 2014 which didn't reoccur in fiscal 2015, as well as additional expenses related to growth and foreign exchange losses, partially offset by increased margins. Our country operations earnings decreased $22.1 million primarily from decreased retail agronomy margins and additional expenses related to growth, which was partially offset by increased grain volumes and margins during the year ended August 31, 2015, compared to the prior year. Earnings from our wholesale crop nutrients business increased by $9.0 million for the year ended August 31, 2015, compared to the prior year, primarily due to increased margins, partially offset by decreased volumes. Earnings from our renewable fuels marketing and production operations decreased $10.5 million during the year ended August 31, 2015, primarily due to significantly lower market prices for ethanol which resulted in lower marketing commissions and was partially offset by earnings from the acquisitions of our Annawan, Illinois ethanol plant in our fourth quarter of fiscal 2015 and our Rochelle, Illinois ethanol plant in the fourth quarter of fiscal 2014. Our processing and food ingredients business experienced an increase in earnings of $111.0 million for the year ended August 31, 2015 compared with the prior year, primarily due to a non-cash

impairment charge in fiscal 2014 of $74.5 million related to certain assets in Israel. In addition, we had a decrease in operating expenses at our plants related to a reduction in the price of natural gas as well as increased margins.

Corporate and Other generated income before income taxes of $80.4 million for the year ended August 31, 2015 compared to $189.5 million during the previous year, a decrease in earnings of $109.1 million (58%). The decrease was primarily related to a $109.2 million gain associated with the contribution of our Horizon Milling assets to the Ardent Mills joint venture formed during fiscal 2014. See Note 4, Investments, to our audited consolidated financial statements included in this Annual Report on Form 10-K for additional information.

Net Income attributable to CHS Inc . Consolidated net income attributable to CHS Inc. for the year ended August 31, 2015 was $781.0 million compared to $1,081.4 million for the year ended August 31, 2014, which represents a $300.4 million decrease (28%).

Revenues . Consolidated revenues were $34.6 billion for the year ended August 31, 2015 compared to $42.7 billion for the year ended August 31, 2014, which represents an $8.1 billion decrease (19%).

Our Energy segment revenues of $8.2 billion, after elimination of intersegment revenues, decreased by $3.4 billion (29%) during the year ended August 31, 2015, compared to $11.6 billion during the year ended August 31, 2014. During the years ended August 31, 2015 and 2014, our Energy segment recorded revenues from sales to our Ag segment of $484.0 million and $600.4 million, respectively, which are eliminated as part of the consolidation process. Refined fuels revenues decreased $2.9 billion (29%), all of which was related to a decrease in the net average selling price, compared to the prior year. The sales price of refined fuels products decreased $0.88 per gallon (28%), compared to the previous year. Propane revenues decreased $463.1 million (34%), of which $399.4 million was attributable to a decrease in the net average selling price and $63.7 million was related to a decrease in volumes. The volumes of our propane products decreased due to an extremely cold winter in fiscal 2014 compared to fiscal 2015 and the prices decreased due to a condensed crop drying season in fiscal 2014 which drove prices up that didn't reoccur in fiscal 2015. Propane sales volume decreased 5%, and the average selling price of propane decreased $0.41 per gallon (31%), when compared to the previous year.

Our Ag segment revenues of $26.3 billion, after elimination of intersegment revenues, decreased $4.7 billion (15%) during the year ended August 31, 2015 compared to $31.0 billion for the year ended August 31, 2014.

Grain revenues in our Ag segment totaled $17.2 billion and $20.7 billion during the years ended August 31, 2015 and 2014, respectively. Of the grain revenues decrease of $3.5 billion (17%), $3.1 billion is due to decreased average grain selling prices, with the remaining decrease driven by a $329.1 million net decrease in volume, compared to the prior year. The average sales price of all grain and oilseed commodities sold reflected a decrease of $1.14 per bushel (15%), when compared to the prior year. Wheat, soybeans, and corn had decreased volumes, compared to the year ended August 31, 2014.

Our processing and food ingredients revenues in our Ag segment of $1.6 billion for the year ended August 31, 2015 decreased $243.4 million (14%), when compared to the prior year. The net decrease in revenues is comprised of a $462.4 million decrease in the average selling price, partially offset by a $219.0 million increase in volumes of our oilseed products sold as compared to the year ended August 31, 2014. Typically, changes in average selling prices of oilseed products are primarily driven by the average market prices of soybeans.

Wholesale crop nutrient revenues in our Ag segment totaled $2.5 billion and $2.8 billion during the years ended August 31, 2015 and 2014, respectively, for a decrease of $331.2 million (12%). Of this decrease, $274.8 million was related to a decrease in volumes and $56.4 million was related to a decrease in average fertilizer selling prices, during the year ended August 31, 2015, compared to the prior fiscal year. Our wholesale crop nutrient volumes decreased 10% and the average sales price of all fertilizers sold reflected a decrease of $8.52 per ton (2%), during the year ended August 31, 2015, compared with the previous year.

Our renewable fuels revenue from our marketing and production operations decreased $548.4 million during the year ended August 31, 2015 compared to the year ended August 31, 2014. The change was primarily the result of a decrease in the average sales price of $0.62 (26%) per gallon which accounted for $581.5 million of the decrease. The lower average selling price of our ethanol was impacted by the decline in the price of traditional fuels. The impact of lower prices was partially offset by higher volumes which increased revenues by $33.1 million. The increase in volumes sold is mostly due to the acquisition of our Rochelle, Illinois ethanol plant in our fourth quarter of fiscal 2014.

Our Ag segment other product revenues, primarily feed and farm supplies, of $3.0 billion decreased by $133.1 million (4%) during the year ended August 31, 2015 compared to the year ended August 31, 2014, primarily due to a decrease in our country operations retail sales of feed and the sales price of energy related products.

Total revenues include other revenues generated primarily within our Ag segment and Corporate and Other. Our Ag segment's country operations elevators and agri-service centers derive other revenues from activities related to production agriculture, which include grain storage, grain cleaning, fertilizer spreading, crop protection spraying and other associated services of this nature. In addition, our grain marketing operations receive other revenues at our export terminals from activities related to loading vessels. Corporate and Other derives revenues primarily from our financing, hedging and insurance operations.

Cost of Goods Sold .  Consolidated cost of goods sold was $33.1 billion for the year ended August 31, 2015, compared to $41.0 billion for the year ended August 31, 2014, which represents a $7.9 billion (19%) decrease.

Our Energy segment cost of goods sold, after elimination of intersegment costs, decreased by approximately $3.1 billion (29%) to $7.5 billion during the year ended August 31, 2015, compared to the prior year. The decrease in cost of goods sold is primarily due to decreases in our refined fuels and propane business. Specifically, refined fuels cost of goods sold decreased $2.6 billion (29%), which reflects a $0.78 per gallon (28%) decrease in the average cost of refined fuels when compared to the prior year. The cost of goods sold of propane decreased $482.6 million (35%), primarily from an average cost decrease of $0.43 per gallon (32%) and a 5% decrease in volumes when compared to the prior year. The volumes of our propane products decreased due to an extremely cold winter in fiscal 2014 compared to fiscal 2015 and the prices decreased due to a condensed crop drying season in fiscal 2014 which drove prices up that didn't reoccur in fiscal 2015.

Our Ag segment cost of goods sold, after elimination of intersegment costs, decreased by $4.8 billion (16%) to $25.6 billion, during the year ended August 31, 2015, compared to the prior year. Grain cost of goods sold in our Ag segment totaled $16.8 billion and $20.3 billion during the year ended August 31, 2015 and 2014, respectively. The costs of grains and oilseed procured through our Ag segment decreased $3.5 billion compared to the year ended August 31, 2014. The majority of the decrease was driven by a lower average cost per bushel of $1.15 (16%), which accounted for $3.2 billion of the decrease, with the remainder attributable to a 2% decrease in volumes contributing $323.0 million to the decrease, for the year ended August 31, 2015 compared to the prior year. The average month-end market price per bushel of soybeans and spring wheat decreased, partially offset by increases in corn, compared to the previous year.

Our processing and food ingredients cost of goods sold in our Ag segment of $1.5 billion decreased $344.8 million (19%) for the year ended August 31, 2015, compared to the year ended August 31, 2014. This decrease was primarily due to a decrease in the cost of soybeans purchased, partially offset by higher volumes. There was also a non-cash $74.5 million impairment charge related to certain assets in Israel recorded in fiscal 2014.

Wholesale crop nutrients cost of goods sold in our Ag segment totaled $2.3 billion and $2.7 billion during the years ended August 31, 2015 and 2014, respectively, for a decrease of $349.0 million (13%). This decrease is comprised of a decrease in the average cost per ton of fertilizer of $13.13 (4%), and a decrease in the tons sold of 10%, when compared to the prior year.

Renewable fuels cost of goods sold associated with our marketing and production operations decreased $560.1 million for the year ended August 31, 2015, compared to the year ended August 31, 2014. This was primarily from a decrease in the average cost per gallon of $0.63 (27%) which was partially offset by an increase in volumes, when compared to the prior year. The increase in volumes was due to the Rochelle, Illinois ethanol plant we acquired in the fourth quarter of fiscal 2014.

Our Ag segment other product cost of goods sold, primarily feed and farm supplies, decreased $126.4 million (5%) for the year ended August 31, 2015, compared to the year ended August 31, 2014, primarily the result of decreased country operations retail sales of feed and the purchase price of energy related products.

Marketing, General and Administrative .  Marketing, general and administrative expenses of $775.4 million for the year ended August 31, 2015, increased by $172.8 million (29%) compared to the prior year. The net increase in fiscal 2015 was primarily due to a $116.5 million charge related to our decision not to proceed with the development of a nitrogen fertilizer plant in Spiritwood, North Dakota. The remaining increase is due to additional head count to support our operations and expansion, increased bad debt provision related to an international customer and increased information technology maintenance and marketing costs.

Gain/Loss on Investments. Gain on investments for the year ended August 31, 2015 decreased by $108.9 million compared to the year ended August 31, 2014, related primarily to a $109.2 million gain in fiscal 2014 associated with the contribution of our Horizon Milling assets to the Ardent Mills joint venture that did not reoccur in fiscal 2015. See Note 4, Investments, to our audited consolidated financial statements included in this Annual Report on Form 10-K for additional information.

Interest expense, net .  Net interest of $60.3 million for the year ended August 31, 2015 decreased $79.9 million compared to the previous year. Approximately $48.8 million of the decrease was related to capitalized interest associated with our ongoing capital projects, and $36.1 million was associated with a decrease in patronage earned by the noncontrolling interests of NCRA (now known as CHS McPherson). These were partially offset by a gain of $13.5 million on interest rate swaps in the second quarter of fiscal 2014 that didn't reoccur in fiscal 2015.

Equity Income from Investments .  Equity income from investments of $107.9 million for the year ended August 31, 2015, increased by less than 1% compared to the year ended August 31, 2014. We record equity income or loss from the investments in which we have an ownership interest of 50% or less and have significant influence, but not control, for our proportionate share of income or loss reported by the entity, without consolidating the revenues and expenses of the entity in our Consolidated Statements of Operations.

Income Taxes.  Income tax benefit was $12.2 million for the year ended August 31, 2015 compared with income tax expense of $48.3 million for the year ended August 31, 2014, resulting in effective tax rates of (1.6%) and 4.3%, respectively. The decrease in the effective tax rate was driven by the combination of deferred tax benefits of $30.8 million during the third quarter of fiscal 2015 related to the issuance of non-qualified equity certificates in fiscal 2013 and 2014 and, to a lesser extent, $19.3 million from the recognition of Kansas tax credits generated by NCRA (now known as CHS McPherson). The federal and state statutory rate applied to nonpatronage business activity was 38.1% for both years ended August 31, 2015 and 2014. The income taxes and effective tax rate vary each year based upon profitability and nonpatronage business activity during each of the comparable years.

Noncontrolling Interests.  Net loss attributable to noncontrolling interests was $0.7 million for the year ended August 31, 2015 compared to net income of $1.6 million for the year ended August 31, 2014, a decrease of $2.3 million.

Comparison of the years ended August 31, 2014 and 2013

General .  We recorded income before income taxes of $1,131.3 million during the twelve months ended August 31, 2014, compared to $1,086.0 million recorded during the twelve months ended August 31, 2013. Operating results reflected a change in the mix of pretax earnings which, as discussed below, resulted in increased pretax income for Corporate and Other, partially offset by decreases in our Energy and Ag segments.

Our Energy segment generated income before income taxes of $728.4 million for the year ended August 31, 2014 compared to $810.9 million in the year ended August 31, 2013, representing a decrease of $82.5 million (10%), primarily due to reduced refining margins. Earnings in our refined fuels business decreased, which was partially offset by increases in our propane, lubricants, and transportation businesses during the year ended August 31, 2014, when compared to the same twelve-month period of the previous year. We are subject to the Renewable Fuel Standard ("RFS") which requires refiners to blend renewable fuels (e.g., ethanol, biodiesel) into their finished transportation fuels or purchase renewable energy credits, known as Renewable Identification Numbers ("RIN"s), in lieu of blending. The EPA generally establishes new annual renewable fuel percentage standards for each compliance year in the preceding year. We generate RINs in our marketing operations under the RFS, however it is not enough to meet the needs of our refining capacity and RINs must be purchased on the open market. Since January 2013, the price of RINs has been extremely volatile. The EPA suggested that it would reduce the renewable fuels mandate for 2014 under the RFS, which has caused RINs prices to decline, however, the mandate was not issued prior to August 31, 2014.

Our Ag segment generated income before income taxes of $213.4 million for the year ended August 31, 2014, compared to $202.8 million in the year ended August 31, 2013, an increase in earnings of $10.6 million (5%). The increase was primarily related to our grain marketing earnings which increased by $49.6 million during the year ended August 31, 2014, compared to the prior period, primarily due to strong logistical performance in North America. Our country operations earnings increased $17.0 million during the year ended August 31, 2014, compared to the prior year. Overall agronomy and grain margins as well as service income increased for retail operations. Earnings from our wholesale crop nutrients business increased by $6.3 million for the year ended August 2014, compared to the prior year, primarily due to increased volumes and margins. Earnings from our renewable fuels marketing and production operations increased $22.3 million during the year ended August 31, 2014, primarily due to significantly higher volumes, partly due to the acquisition of our Rochelle, Illinois ethanol

plant in the fourth quarter of fiscal 2014, partially offset by lower market prices for ethanol which resulted in lower marketing commissions. These items were mostly offset by decreased earnings in our processing and food ingredients operations of $84.6 million in fiscal 2014. The decrease consisted of a non-cash $74.5 million charge related to certain assets in Israel in fiscal 2014. See Note 17, Acquisitions, to our audited consolidated financial statements included in this Annual Report on Form 10-K for additional information.

Corporate and Other generated income before income taxes of $189.5 million for the year ended August 31, 2014 compared to $72.3 million during the previous year, an increase in earnings of $117.2 million. The increase was primarily related to a $109.2 million gain associated with the contribution of our Horizon Milling assets to the newly formed Ardent Mills joint venture. See Note 4, Investments, to our audited consolidated financial statements included in this Annual Report on Form 10-K for additional information.

Net Income attributable to CHS Inc .  Consolidated net income attributable to CHS Inc. for the year ended August 31, 2014 was $1,081.4 million compared to $992.4 million for the year ended August 31, 2013, which represented an $89.0 million increase (9%).

Revenues .  Consolidated revenues were $42.7 billion for the year ended August 31, 2014 compared to $44.5 billion for the year ended August 31, 2013, which represented a $1.8 billion decrease (4%).

Our Energy segment revenues of $11.6 billion, after elimination of intersegment revenues, increased by $630.8 million (6%) during the year ended August 31, 2014, compared to $10.9 billion during the year ended August 31, 2013. During the years ended August 31, 2014 and 2013, our Energy segment recorded revenues from sales to our Ag segment of $600.4 million and $481.5 million, respectively, which are eliminated as part of the consolidation process. Propane revenues increased $670.7 million (89%), of which $351.6 million was related to an increase in the net average selling price and $319.1 million was attributable to volume resulting from demand caused by a shortened harvest season and related corn drying activity as well as colder than normal temperatures, when compared to the previous year. Propane sales volume increased 42%, while the average selling price of propane increased $0.34 per gallon (33%) in comparison to the previous year. Refined fuels revenues partially offset the increases in revenues previously described with a decrease in refined fuels of $20.9 million (less than 1%), of which $268.8 million related to a net average selling price decrease mostly offset by an increase in volumes of $247.9 million, compared to the previous year. The sales price of refined fuels products decreased $0.09 per gallon (3%), and sales volumes increased by 3%, when compared to the previous year.

Our Ag segment revenues of $31.0 billion, after elimination of intercompany intersegment revenues, decreased $2.5 billion (7%) during the year ended August 31, 2014 compared to $33.5 billion reported for the year ended August 31, 2013.

Grain revenues in our Ag segment totaled $20.7 billion and $23.8 billion during the years ended August 31, 2014 and 2013, respectively. Of the grain revenues decrease of $3.1 billion (13%), $3.7 billion was due to decreased average grain selling prices, partially offset by an increase of $579.3 million due to a net increase in sales volume of 2% during the year ended August 31, 2014, compared to the prior year. The average sales price of all grain and oilseed commodities sold reflected a decrease of $1.51 per bushel (15%) over the previous year. Wheat, soybeans, and corn had increased volumes, compared to the year ended August 31, 2013.

Our processing and food ingredients revenues in our Ag segment of $1.8 billion for the year ended August 31, 2014, decreased $83.5 million when compared to the year ended August 31, 2013. We experienced decreases in revenue of $100.5 million related to decreased average selling prices, which was partially offset by an increase of $17.0 million from the volume associated with our oilseed products as compared to the year ended August 31, 2013. Typically, changes in average selling prices of oilseed products are primarily driven by the average market prices of soybeans.

Wholesale crop nutrient revenues in our Ag segment totaled $2.6 billion and $2.7 billion during the years ended August 31, 2014 and 2013, respectively. Of the wholesale crop nutrient revenues decrease of $108.0 million (4%), $592.7 million was related to decreased average fertilizer selling prices, partially offset by $484.7 million related to an increase in volumes, during the year ended August 31, 2014, compared to the previous fiscal year. Our wholesale crop nutrient volumes increased 18% during the year ended August 31, 2014 compared with the previous year. The average sales price of all fertilizers sold reflected a decrease of $81.29 per ton (19%) compared with the previous year.

Our renewable fuels revenue from our marketing and production operations of $2.2 billion increased $646.2 million (42%) for the year ended August 31, 2014, compared to the year ended August 31, 2013. The increase was primarily the result of significantly higher volumes (50%) which accounted for $779.1 million of the increase, partially offset by a decrease in the average selling price of $0.14 per gallon (6%) totaling $132.9 million, when compared to the previous year. The increase in

volumes sold was primarily due to additional marketing agreements for four ethanol plants. The lower average selling price of our ethanol was impacted by the decline in the price of traditional fuels.

Our Ag segment other product revenues, primarily feed and farm supplies, of $3.4 billion increased by $125.3 million during the year ended August 31, 2014 compared to the year ended August 31, 2013, primarily due to an increase in our country operations retail merchandise revenues. Other revenues within our Ag segment of $191.4 million during the year ended August 31, 2014, increased $41.2 million (27%) compared to the year ended August 31, 2013.

Total revenues include other revenues generated primarily within our Ag segment and Corporate and Other. Our Ag segment's country operations elevators and agri-service centers derive other revenues from activities related to production agriculture, which include grain storage, grain cleaning, fertilizer spreading, crop protection spraying and other associated services. In addition, our grain marketing operations receive other revenues at our export terminals from activities related to loading vessels. Corporate and Other derives revenues primarily from our financing, hedging and insurance operations.

Cost of Goods Sold .  Consolidated cost of goods sold was $41.0 billion for the year ended August 31, 2014, compared to $42.7 billion for the year ended August 31, 2013, representing a $1.7 billion (4%) decrease.

Our Energy segment cost of goods sold, after elimination of intersegment costs, increased by approximately $812.6 million (8%) to $10.6 billion during the year ended August 31, 2014, compared to the prior year. The increase in cost of goods sold was primarily due to increased costs associated with refined fuels and propane products. Specifically, refined fuels cost of goods sold increased $187.4 million (2%), which reflected a 3% increase in the volume from the prior year. The cost of goods sold of propane increased $640.1 million (86%) primarily from an average cost increase of $0.32 per gallon (30%) and a 42% increase in volumes resulting from demand caused by a condensed harvest and associated corn drying activity as well as colder than normal temperatures, when compared to the previous year.

Our Ag segment cost of goods sold, after elimination of intersegment costs, decreased by $2.5 billion (8%) to $30.4 billion, during the year ended August 31, 2014, compared to the prior year. The majority of the decrease was driven by the lower grains and oilseed costs, which decreased by $3.5 billion (15%) in the year ended August 31, 2014 compared to the prior year. This was primarily the result of a $1.67 (17%) decrease in the average cost per bushel. This decrease was partially offset by a 3% net increase in bushels sold, as compared to the prior year. The average month-end market price per bushel of soybeans, corn and spring wheat decreased compared to the previous year.

Our processing and food ingredients cost of goods sold in our Ag segment of $1.9 billion was flat for the year ended August 31, 2014, compared to the year ended August 31, 2013. We experienced an increase in volumes sold which was offset by a non-cash $74.5 million impairment charge related to certain assets in Israel recorded in fiscal 2014.

Wholesale crop nutrients cost of goods sold in our Ag segment totaled $2.4 billion and $2.6 billion during the years ended August 31, 2014 and 2013, respectively. The net decrease of $171.5 million (7%) was comprised of a decrease in the average cost per fertilizer ton of $88.38 (21%), partially offset by an 18% increase in tons sold, when compared to the prior year.

Renewable fuels cost of goods sold associated with our marketing and production operations increased $621.5 million (41%) for the year ended August 31, 2014, compared to the year ended August 31, 2013. This was primarily from an increase in volumes of 50% which was partially offset by a decrease in the average cost per gallon of $0.16 (7%), when compared to the prior year. The increase in volumes was primarily due to additional marketing agreements with four ethanol plants.

Our Ag segment other product cost of goods sold, primarily feed and farm supplies, as of August 31, 2014 was $2.9 billion, an increase of $84.8 million (3%) compared to the prior year and was primarily the result of an increase in our country operations retail volumes.

Marketing, General and Administrative .  Marketing, general and administrative expenses of $602.6 million for the year ended August 31, 2014, increased by $49.0 million (9%) compared to the prior year. The net increase in fiscal 2014 was driven by our grain marketing and international operations, and to a lesser extent, our processing and food ingredients operations, including our ethanol facility acquired in fiscal 2014, partially offset by a decrease in our energy operations.

Gain/Loss on Investments. Gain on investments for the year ended August 31, 2014 increased by $114.1 million compared to the year ended August 31, 2013, related primarily to a $109.2 million gain associated with the contribution of our Horizon Milling assets to the newly formed Ardent Mills joint venture. See Note 4, Investments, to our audited consolidated financial statements included in this Annual Report on Form 10-K for additional information.

Interest expense, net .  Net interest of $140.3 million for the year ended August 31, 2014 decreased $96.4 million compared to the previous year. Interest expense for the years ended August 31, 2014 and 2013 was $155.8 million and $253.5 million, respectively. The decrease in interest expense of $97.7 million was primarily due to a $78.2 million decrease in patronage earned by the noncontrolling interests of NCRA (now known as CHS McPherson) and, to a lesser extent, a gain on interest rate swaps of $13.5 million, when compared with the previous year.

Equity Income from Investments .  Equity income from investments of $107.4 million for the year ended August 31, 2014, increased $10.1 million (10%) compared to the year ended August 31, 2013. We record equity income or loss from the investments in which we have an ownership interest of 50% or less and have significant influence, but not control, for our proportionate share of income or loss reported by the entity, without consolidating the revenues and expenses of the entity in our Consolidated Statements of Operations.

Income Taxes.  Income tax expense was $48.3 million for the year ended August 31, 2014 compared with $89.7 million for the year ended August 31, 2013, resulting in effective tax rates of 4.3% and 8.3%, respectively. The decrease in the tax rate for fiscal 2014 was driven by a combination of excise tax credit claims made for the years 2007 through 2012 related to the blending and sale of renewable fuels deducted for income taxes of $46.3 million, net of reserves, and to a lesser extent the release of reserves related to the expiration of certain statutes of limitations of $20.9 million. The federal and state statutory rate applied to nonpatronage business activity was 38.1% for both of the years ended August 31, 2014 and 2013. The income taxes and effective tax rate vary each year based upon profitability and nonpatronage business activity during each of the comparable years.

Noncontrolling Interests.  Income attributable to noncontrolling interests of $1.6 million for the year ended August 31, 2014 decreased by $2.4 million compared to the year ended August 31, 2013.

Liquidity and Capital Resources

In assessing our financial condition, we consider factors such as working capital and internal benchmarking related to our applicable financial covenants. We fund our operations primarily through a combination of cash flows from operations and revolving credit facilities. We fund our capital expenditures and growth primarily through long-term debt financing and issuance of preferred stock.

On August 31, 2015 and August 31, 2014 , we had working capital, defined as current assets less current liabilities, of $2.8 billion and $3.2 billion , respectively. Our current ratio, defined as current assets divided by current liabilities, was 1.5 and 1.5 as of August 31, 2015 and August 31, 2014 , respectively.

As of August 31, 2015 we had cash and cash equivalents of $953.8 million , total equities of $7.7 billion , long-term debt of $1.4 billion and notes payable of $1.2 billion . Our capital allocation priorities include maintaining our assets, paying our dividends, returning cash to our member-owners in the form of patronage refunds, investing to grow our business and taking advantage of strategic opportunities. Our primary sources of cash in fiscal 2015 were net cash flows from operations and equity financing through the issuance of preferred stock. Primary uses of cash were capital expenditures, dividends (patronage and preferred stock), business acquisitions, retirement of equity certificates, and payments on indebtedness. We believe that cash generated by operating activities, along with available borrowing capacity under our revolving credit facility, will be sufficient to support our operations in fiscal 2016, including dividend payments, capital expenditures and required interest payments related to our long-term debt.

In addition to our working capital and other normal liquidity requirements, we expect to utilize available liquidity, including cash and cash equivalents, to fund our ongoing capital expenditures. For fiscal 2016, we expect total capital expenditures to be approximately $1.1 billion . Included in that amount is approximately $392.0 million for the acquisition of property, plant and equipment and major repairs at our Laurel, Montana and McPherson, Kansas refineries. That amount includes $40.0 million for the remainder of a multi-year project to replace a coker at the McPherson refinery with an expected total cost of $579.0 million and expected completion in fiscal 2016. We incurred $167.4 million , $186.8 million and $124.0 million of costs related to the coker project during the years ended August 31, 2015, 2014 and 2013, respectively. We also began a $353.0 million expansion at the McPherson refinery during the year ended August 31, 2013 which is anticipated to be completed in fiscal 2016. We incurred $159.2 million , $128.3 million and $25.0 million of costs related to the expansion during the years ended August 31, 2015, 2014 and 2013, respectively.

We announced in September 2014 that our Board of Directors had approved plans to begin construction of a fertilizer manufacturing plant in Spiritwood, North Dakota that was anticipated to cost more than $3.0 billion. We planned to finance the project through a combination of issuance of preferred stock and debt. In September 2014 and January 2015, we took initial steps in the financing of this project by issuing shares of Class B Series 3 Preferred Stock and Class B Series 4 Preferred Stock, respectively, as described in "Cash Flows from Financing Activities - Other Financing" below. These preferred stock offerings yielded approximately $977.8 million in cash after underwriting discounts and offering expenses.

In August 2015 we announced our intention to not move forward with the construction of the Spiritwood facility. We instead entered into an agreement with CF Industries to invest $2.8 billion in cash in exchange for an 11.4% membership interest (based on product tons) in CF Nitrogen and a separate agreement to purchase nitrogen fertilizer products from that entity over an 80-year term. The closing date for our investment in CF Nitrogen is anticipated to be February 1, 2016, and we intend to finance this transaction using additional long-term debt in combination with existing credit facilities and available cash.

As of August 31, 2015 we had access to a five-year, unsecured revolving credit facility with a committed amount of $2.5 billion that expires in June 2018, which had no amounts outstanding as of August 31, 2015 or 2014. The financial covenants for this credit facility require us to have, as of the end of each fiscal quarter, a minimum consolidated net worth, as defined in the credit agreements of $2.5 billion, and a consolidated funded debt to consolidated cash flow ratio of no greater than 3.00 to 1.00. A third financial covenant required that our ratio of adjusted consolidated funded debt to adjusted consolidated equity not exceed 0.80 to 1.00, as measured at the end of each fiscal quarter. As of August 31, 2015, we were in compliance with all covenants.

In September of 2015, this facility was amended and restated as a five-year, unsecured revolving credit facility with a committed amount of $3.0 billion that expires in September 2020. In addition, the minimum consolidated net worth as defined in the credit agreement was increased to $3.5 billion, and the maximum consolidated funded debt to consolidated cash flow was increased to 3.50 to 1.00.

Our revolving credit facility is established with a syndication of domestic and international banks, and our inventories and receivables financed with them are highly liquid. We believe our current cash balances and our available capacity on our committed lines of credit will provide adequate liquidity to meet our working capital needs.

In addition, our wholly-owned subsidiary, CHS Capital, makes seasonal and term loans to member cooperatives, businesses and individual producers of agricultural products included in our cash flows from investing activities, and has its own financing explained in further detail below under "Cash Flows from Financing Activities."

Cash Flows from Operations

Cash flows from operations are generally affected by commodity prices and the seasonality of our businesses. These commodity prices are influenced by a wide range of factors beyond our control, including weather, crop conditions, drought, the availability and the adequacy of supply and transportation, government regulations and policies, world events, and general political and economic conditions. These factors are described in the Cautionary Statement for Purposes of the Safe Harbor Provisions of the Private Securities Litigation Reform Act of 1995 section and may affect net operating assets and liabilities, and liquidity.

Cash flows provided by operating activities were $570.0 million , $1.4 billion and $2.5 billion for the years ended August 31, 2015, 2014 and 2013 , respectively. The fluctuation in cash flows between fiscal 2015 and fiscal 2014 is primarily the result of significant uses of cash related to net changes in operating assets and liabilities during the year ended August 31, 2015 compared to the overall cash inflows associated with changes in operating assets and liabilities during the year ended August 31, 2014.

Our operating activities provided net cash of $570.0 million during the year ended August 31, 2015 . The cash provided by operating activities resulted from net income including noncontrolling interests of $780.3 million and net non-cash expenses and cash distributions from equity investments of $450.2 million , partially offset by a decrease in cash flows due to changes in net operating assets and liabilities of $660.5 million . The primary components of net non-cash expenses and cash distributions from equity investments include depreciation and amortization, including amortization of major repair costs, of $401.4 million and long-lived asset impairment charges of $103.7 million , partially offset by a gain of $36.3 million on our crack spread contingent consideration liability and net equity investment activity of $26.9 million . The decrease in cash flows from changes in net operating assets and liabilities was caused primarily by decreases in accounts payable and accrued expenses and customer advance payments, partially offset by decreases in receivables and inventories. These decreases were

driven by decreases in commodity prices on August 31, 2015, when compared to August 31, 2014. On August 31, 2015, the per bushel market prices of two of our primary grain commodities, soybeans and spring wheat, decreased by $1.92 (18%) and $1.19 (19%), respectively, when compared to the spot prices on August 31, 2014. The per bushel market price of our third primary commodity, corn, increased by $0.33 (9%) when compared to the spot price on August 31, 2014. In general, crude oil market prices decreased $47 per barrel (49%) on August 31, 2015 when compared to August 31, 2014. Comparing the same periods, fertilizer commodity prices affecting our wholesale crop nutrients and country operations retail businesses reflected decreases of up to 26%, depending on the specific products, compared to prices on August 31, 2014. In addition, slight increases in grain inventory quantities on August 31, 2015 compared to the prior year partially offset the impact that lower grain commodity prices had on net operating assets and liabilities on August 31, 2015.

Our operating activities provided net cash of $1.4 billion during the year ended August 31, 2014. Net income including noncontrolling interests of $1.1 billion , net non-cash expenses and cash distributions from equity investments of $234.9 million and an increase in cash flows due to changes in net operating assets and liabilities of $123.4 million contributed to the net cash provided by operating activities. The primary components of net non-cash expenses and cash distributions from equity investments included depreciation and amortization, including amortization of major repair costs, of $351.3 million , partially offset by gains on the sale of investments of $114.2 million , primarily due to a $109.2 million gain associated with the contribution of our Horizon Milling assets to the newly formed Ardent Mills joint venture. See Note 4, Investments, to our audited consolidated financial statements included in this Annual Report on Form 10-K for additional information. The cash inflow resulting from the decrease in net operating assets and liabilities was caused primarily by a decrease in commodity prices on August 31, 2014, when compared to August 31, 2013. On August 31, 2014, the per bushel market prices of our primary grain commodities, corn, spring wheat, and soybeans, decreased by $1.23 (26%), $1.15 (16%), and $2.68 (19%), respectively, when compared to the spot prices on August 31, 2013. In general, crude oil market prices decreased $12 per barrel (11%) on August 31, 2014 when compared to August 31, 2013. On August 31, 2014, fertilizer commodity prices affecting our wholesale crop nutrients and country operations retail businesses reflected increases up to 29%, depending on the specific products, compared to prices on August 31, 2013. In addition, increased grain inventory quantities on August 31, 2014 compared to the prior year, partially offset the impact that lower grain commodity prices had on net operating assets and liabilities on August 31, 2014.

Our operating activities provided net cash of $2.5 billion during the year ended August 31, 2013. Net income including noncontrolling interests of $996.3 million , net non-cash expenses and cash distributions from equity investments of $375.3 million and an increase in cash flows due to changes in net operating assets and liabilities of $1.1 billion contributed to the net cash provided by operating activities. The primary components of net non-cash expenses and cash distributions from equity investments included depreciation and amortization, including amortization of major repair costs, of $311.4 million , deferred taxes of $92.7 million and the loss on our crack spread contingent liability of $23.1 million , which were partially offset by income from equity investments, net of distributions from those investments, of $34.6 million . The cash inflow resulting from the decrease in net operating assets and liabilities was caused primarily by decreases in commodity prices and inventory quantities, and was reflected in decreased receivables, inventories, margin deposits and derivative assets, partially offset by an increase in derivative liabilities on August 31, 2013 when compared to August 31, 2012. On August 31, 2013, the per bushel market prices of our primary grain commodities, corn, spring wheat and soybeans, decreased by $3.21 (40%), $2.02 (22%) and $4.07 (23%), respectively, when compared to the spot prices on August 31, 2012. In general, crude oil market prices increased $11 per barrel (12%) on August 31, 2013 when compared to August 31, 2012. On August 31, 2013, fertilizer commodity prices affecting our wholesale crop nutrients and country operations retail businesses reflected decreases between 19% and 31%, depending on the specific products, compared to prices on August 31, 2012. A decrease in grain inventory quantities in our Ag segment of 44.1 million bushels (30%) also contributed to the decrease in net operating assets and liabilities when comparing inventories at August 31, 2013 to August 31, 2012.

Cash Flows from Investing Activities

For the years ended August 31, 2015, 2014 and 2013 , the net cash flows used in our investing activities totaled $1.9 billion , $1.3 billion and $495.3 million , respectively.

Total cash expenditures for the acquisition of property, plant and equipment totaled $1.2 billion , $919.1 million and $619.9 million for the years ended August 31, 2015, 2014 and 2013 , respectively. The significant increases from fiscal 2013 to fiscal 2014 and from fiscal 2014 to fiscal 2015 were primarily related to multi-year projects involving the replacement of a coker and expansion of capacity at our CHS McPherson refinery as discussed below.

Expenditures for major repairs related to our refinery turnarounds were $201.7 million , $2.9 million and $73.6 million during the years ended August 31, 2015, 2014 and 2013 , respectively. Refineries have planned major maintenance to overhaul, repair, inspect and replace process materials and equipment (referred to as "turnaround") which typically occur for a five-to-six

week period every 2-4 years. Both our Laurel, Montana refinery and our McPherson, Kansas refinery had turnarounds during the year ended August 31, 2015. Neither of the refineries has turnarounds scheduled for fiscal 2016.

Cash acquisitions of businesses, net of cash acquired, totaled $305.2 million , $281.5 million and $12.7 million during the years ended August 31, 2015, 2014 and 2013 , respectively. The fiscal 2015 activity included our Patriot Renewable Fuels and Northstar Agri Industries acquisitions in our Ag segment. See Note 17, Acquisitions, to our audited consolidated financial statements included in this Annual Report on Form 10-K for additional information.

Investments in joint ventures and other entities during the years ended August 31, 2015, 2014 and 2013 , totaled $64.3 million , $80.1 million and $21.4 million , respectively. Of the amount invested in joint ventures in fiscal 2014, $48.2 million was associated with the winding down of our Horizon Milling joint venture and ownership interest that was contributed to our Ardent Mills joint venture.

Changes in notes receivable for the years ended August 31, 2015 and 2014 resulted in net decreases in cash flows of $184.1 million and $184.1 million , respectively. The primary cause of the decreases in cash flows during both periods relates to increases in CHS Capital notes receivable. Changes in notes receivable for the year ended August 31, 2013 resulted in a net increase in cash flows of $211.9 million . The primary cause of the net increase in cash flows during fiscal 2013 was a decrease in CHS Capital notes receivable of $189.3 million and a decrease in CHS McPherson (then known as NCRA) notes receivable, compared to August 31, 2012.

Partially offsetting our cash expenditures for investing activities during the years ended August 31, 2015, 2014 and 2013 , were proceeds from the redemption of investments of $19.9 million , $138.5 million and $13.0 million , respectively. Included in the fiscal 2014 amount is $121.2 million of cash proceeds that were distributed to us as part of our Ardent Mills joint venture. Also partially offsetting our cash expenditures for investing activities during the years ended August 31, 2015, 2014 and 2013 , were proceeds received from the disposal of property, plant and equipment of $11.3 million , $11.7 million and $7.7 million , respectively.

Cash Flows from Financing Activities

For the years ended August 31, 2015 and August 31, 2014, our financing activities provided net cash of $153.8 million and $201.5 million , respectively. For the year ended August 31, 2013, net cash used in our financing activities totaled $478.0 million .

Working Capital Financing:

We finance our working capital needs through lines of credit with domestic and international banks. On August 31, 2015, we had a five-year, unsecured, revolving facility with a committed amount of $2.5 billion, which had no amounts outstanding. This facility was amended and restated in September 2015 with a committed amount of $3.0 billion and a new five year term.

In addition to our primary revolving line of credit, we have a three-year $250.0 million committed revolving pre-export credit facility for CHS Agronegocio Industria e Comercio Ltda ("CHS Agronegocio"), our wholly-owned subsidiary in South America, to provide financing for its working capital needs arising from its purchases and sales of grains, fertilizers and other agricultural products which expires in October 2016. The outstanding balance on this facility was $200.0 million as of August 31, 2015. This facility was amended in October 2015 to conform its financial covenants with those of the five-year, unsecured, revolving facility.

As of August 31, 2015 our wholly-owned subsidiaries, CHS Europe S.a.r.l and CHS Agronegocio, had uncommitted lines of credit of $303.4 million outstanding. In addition, our other international subsidiaries had lines of credit totaling $310.2 million outstanding at August 31, 2015, of which $216.7 million was collateralized. On August 31, 2015 and 2014, we had total short-term indebtedness outstanding on these various facilities and other miscellaneous short-term notes payable totaling $813.7 million and $840.7 million , respectively.

We have two uncommitted commercial paper programs with an aggregate capacity of $125.0 million, with two banks participating in our revolving credit facilities. Terms of our revolving credit facility allow a maximum usage of $100.0 million to pay principal under any commercial paper facility. On August 31, 2015 and 2014, we had no commercial paper outstanding. In September 2015, we amended our five-year, unsecured, revolving facility and eliminated the provision that allowed proceeds to be used to pay principal under a commercial paper facility.

CHS Capital Financing:

Cofina Funding, LLC ("Cofina Funding"), a wholly-owned subsidiary of CHS Capital, had available credit totaling $350.0 million as of August 31, 2015, under note purchase agreements with various purchasers, through the issuance of short-term notes payable. CHS Capital sells eligible commercial loans receivable it has originated to Cofina Funding, which are then pledged as collateral under the note purchase agreements. The notes payable issued by Cofina Funding bear interest at variable rates based on commercial paper with a weighted average rate of 1.04% as of August 31, 2015. There were no borrowings by Cofina Funding utilizing the issuance of commercial paper under the note purchase agreements as of August 31, 2015.

CHS Capital has available credit under master participation agreements with numerous counterparties. Borrowings under these agreements are accounted for as secured borrowings and bear interest at variable rates ranging from 1.64% to 3.70% as of August 31, 2015. As of August 31, 2015, the total funding commitment under these agreements was $145.7 million, of which $35.9 million was borrowed.

CHS Capital sells loan commitments it has originated to ProPartners Financial ("ProPartners") on a recourse basis. The total capacity for commitments under the ProPartners program is $300.0 million. The total outstanding commitments under the program totaled $56.8 million as of August 31, 2015, of which $39.9 million was borrowed under these commitments with an interest rate of 1.62%.

CHS Capital borrows funds under short-term notes issued as part of a surplus funds program. Borrowings under this program are unsecured and bear interest at variable rates ranging from 0.10% to 0.90% as of August 31, 2015, and are due upon demand. Borrowings under these notes totaled $275.8 million as of August 31, 2015.

As of August 31, 2014, there were no borrowings under Cofina Funding through the issuance of commercial paper with $17.6 million of secured borrowings under CHS Capital. CHS Capital borrowings under the ProPartners program and the surplus funds program were $64.6 million and $236.6 million, respectively, as of August 31, 2014.

Long-term Debt Financing:

We use long-term debt agreements with various insurance companies and banks to finance certain of our long-term capital needs, primarily those related to the acquisition of property, plant and equipment.

On August 31, 2015, we had total long-term debt outstanding of approximately $1.4 billion , of which $75.0 million was bank financing, $1.2 billion was private placement debt, $125.9 million was obligations related to capital leases and $44.9 million was other notes and contracts payable. On August 31, 2014, we had total long-term debt outstanding of approximately $1.6 billion , of which $105.0 million was bank financing, $1.3 billion was private placement debt, $155.4 million was obligations related to capital leases and $43.8 million was other notes and contracts payable. Our long-term debt is unsecured except for other notes and contracts in the amount of $0.5 million ; however, restrictive covenants under various agreements have requirements for maintenance of minimum consolidated net worth and other financial ratios. We were in compliance with all debt covenants and restrictions as of August 31, 2015. Long-term debt outstanding as of August 31, 2015 has aggregate maturities, excluding fair value adjustments and capital leases, as follows:

During the years ended August 31, 2015, 2014 and 2013 we borrowed $3.5 million , $1.4 million and $280.0 million , respectively, on a long-term basis. During the years ended August 31, 2015 , 2014 and 2013 , we repaid long-term debt of $170.7 million , $157.8 million and $113.6 million , respectively; and we made principal payments on capital lease obligations of $38.9 million , $39.9 million , and $35.4 million , respectively.

Additional detail on our long-term borrowings and repayments is as follows:

In June 1998, we completed a private placement offering with several insurance companies for long-term debt in the amount of $225.0 million with an interest rate of 6.81%. Repayments were due in equal annual installments during the years 2008 through 2013 and the debt was fully repaid in fiscal 2013.

In October 2002, we completed a private placement with several insurance companies for long-term debt in the amount of $175.0 million, which was layered into two series. The first series of $115.0 million had an interest rate of 4.96% and was due in equal semi-annual installments of approximately $8.8 million during the years 2007 through 2013. The second series of $60.0 million has an interest rate of 5.60% and is due in equal semi-annual installments of approximately $4.6 million during the years 2012 through 2018.

In March 2004, we entered into a note purchase and private shelf agreement with Prudential Capital Group. In April 2007, we amended our Note Purchase and Private Shelf Agreement with Prudential Investment Management, Inc. and several other participating insurance companies to expand the uncommitted facility from $70.0 million to $150.0 million. We borrowed $50.0 million under the shelf arrangement in February 2008, for which the aggregate long-term notes have an interest rate of 5.78% and are due in equal annual installments of $10.0 million during the years 2014 through 2018. In November 2010, we borrowed $100.0 million under the shelf arrangement, for which the aggregate long-term notes have an interest rate of 4.0% and are due in equal annual installments of $20.0 million during the years 2017 through 2021.

In September 2004, we completed a private placement with several insurance companies for long-term debt in the amount of $125.0 million with an interest rate of 5.25%. The debt was due in equal annual installments of $25.0 million during the years 2011 through 2015, and was fully repaid in fiscal 2015.

In October 2007, we completed a private placement with several insurance companies and banks for long-term debt in the amount of $400.0 million with an interest rate of 6.18%. Repayments are due in equal annual installments of $80.0 million during the years 2013 through 2017.

In December 2007, we established a ten-year long-term credit agreement through a syndication of cooperative banks in the amount of $150.0 million, with an interest rate of 5.59%. Repayments are due in equal semi-annual installments of $15.0 million each, from June 2013 through December 2018.

In June 2011, we completed a private placement with certain accredited investors for long-term debt in the amount of $500.0 million, which was layered into four series. The first series of $130.0 million has an interest rate of 4.08% and is due in June 2019. The second series of $160.0 million has an interest rate of 4.52% and is due in June 2021. The third series of $130.0 million has an interest rate of 4.67% and is due in June 2023. The fourth series of $80.0 million has an interest rate of 4.82% and is due in June 2026. Under the agreement, we may from time to time issue additional series of notes pursuant to the agreement, provided that the aggregate principal amount of all notes outstanding at any time may not exceed $1.5 billion.

In March 2013, we issued $100 million of notes with an interest rate of 4.71%, which mature in fiscal 2033, in a private placement to institutional investors.

In July 2013, we issued $80 million and $100 million of notes with interest rates of 3.85% and 3.80%, respectively, which mature in fiscal 2025, in two private placements to institutional investors.

In September of 2015, we amended all outstanding notes to conform their financial covenants to those of the amended and restated five-year, unsecured, revolving facility. In addition, the amended notes contain a provision such that if our ratio of consolidated funded debt to consolidated cash flow is greater than 3.0 to 1.0, the interest rate on all outstanding notes is increased by 0.25% until the ratio declines to 3.0 or less.

In September 2015, we entered into a ten-year term loan with a syndication of banks. The agreement provides for committed term loans in an amount up to $600.0 million, which may be drawn down from time to time, but in no event on more than 10 occasions, from September 4, 2015 until September 4, 2016. Amounts drawn under this agreement that are subsequently repaid or prepaid may not be reborrowed. Principal on the term loans is payable in full on September 4, 2025. Borrowings under the agreement will bear interest at a base rate (or a LIBO rate) plus an applicable margin, or at a fixed rate of interest determined and quoted by the administrative agent under the agreement in its sole and absolute discretion from time to time. The applicable margin will be based on our leverage ratio and ranges between 1.50% and 2.00% for LIBO rate loans and between 0.50% and 1.00% for base rate loans. There are currently no amounts drawn under this agreement.

Other Financing:

During the years ended August 31, 2015 and August 31, 2014 , we made a payment of $66.0 million in each year related to our purchase of the CHS McPherson (formerly NCRA) noncontrolling interests.

During the years ended August 31, 2015 , August 31, 2014 , and August 31, 2013, changes in checks and drafts outstanding resulted in a decrease in cash flows of $43.4 million , $17.8 million and $20.4 million , respectively.

In accordance with our bylaws and by action of the Board of Directors, annual net earnings from patronage sources are distributed to consenting patrons following the close of each fiscal year. Patronage refunds are calculated based on amounts using financial statement earnings. The cash portion of the patronage distribution is determined annually by the Board of Directors, with the balance issued in the form of qualified and/or non-qualified capital equity certificates. Consenting patrons have agreed to take both the cash and qualified capital equity certificate portion allocated to them from our previous fiscal year's income into their taxable income; and as a result, we are allowed a deduction from our taxable income for both the cash distribution and the allocated qualified capital equity certificates, as long as the cash distribution is at least 20% of the total qualified patronage distribution. For the years ended August 31, 2014 and August 31, 2013, 10% of earnings from patronage business was added to our capital reserves and the remaining 90% was primarily distributed during the second fiscal quarters of the years ended August 31, 2015 and August 31, 2014, totaling $821.5 million and $841.1 million , respectively. The cash portion of the qualified distributions was deemed by the Board of Directors to be 40% for fiscal 2014 and 2013. Cash related to these distributions was $271.2 million and $286.8 million and was paid during the years ended August 31, 2015 and August 31, 2014, respectively. During the year ended August 31, 2013, we distributed patronage refunds of $976.0 million , of which the cash portion was $380.9 million .

In accordance with our bylaws and by action of the Board of Directors, 10% of the earnings from patronage business for the year ended August 31, 2015 was added to our capital reserves and the remaining 90%, or an estimated $625.4 million , will be distributed as patronage in fiscal 2016 , in the form of qualified equity certificates and cash. The cash portion of the qualified distribution, determined by the Board of Directors to be 40%, is expected to be approximately $250.2 million and is classified as a current liability on our August 31, 2015 Consolidated Balance Sheet in dividends and equities payable.

Redemptions of capital equity certificates approved by the Board of Directors are divided into two pools, one for non-individuals (primarily member cooperatives) who may participate in an annual retirement program for qualified equities held by them and another for individuals who are eligible for qualified equity redemptions at age 70 or upon death. In accordance with authorization from the Board of Directors, we expect total redemptions related to the year ended August 31, 2015 , that will be distributed in fiscal 2016 , to be an estimated $107.3 million . These expected distributions are classified as a current liability on the August 31, 2015 Consolidated Balance Sheet.

For the years ended August 31, 2015, 2014 and 2013 , we redeemed in cash, qualified equities in accordance with authorization from the Board of Directors, in the amounts of $128.9 million , $99.6 million and $193.4 million , respectively.

The following is a summary of our outstanding preferred stock as of August 31, 2015 , all of which are listed on the Global Select Market of NASDAQ:

We made dividend payments on our preferred stock of $133.7 million , $50.8 million , and $24.5 million , during the years ended August 31, 2015 , 2014 and 2013 , respectively.

Off Balance Sheet Financing Arrangements

Guarantees:

We are a guarantor for lines of credit and performance obligations of related companies. Our bank covenants allow maximum guarantees of $1.0 billion , of which $94.6 million were outstanding on August 31, 2015 . We have collateral for a portion of these contingent obligations. We have not recorded a liability related to the contingent obligations as we do not expect to pay out any cash related to them, and the fair values are considered immaterial. The underlying loans to the counterparties for which we provide guarantees are current as of August 31, 2015 .

Operating leases:

Minimum future lease payments required under noncancelable operating leases as of August 31, 2015 were $249.7 million .

Debt:

There is no material off balance sheet debt.

Contractual Obligations

We had certain contractual obligations at August 31, 2015 , which require the following payments to be made:

Critical Accounting Policies

Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The preparation of these consolidated financial statements requires the use of estimates as well as management's judgments and assumptions regarding matters that are subjective, uncertain or involve a high degree of complexity, all of which affect the results of operations and financial condition for the periods presented. We believe that of our significant accounting policies, the following may involve a higher degree of estimates, judgments and complexity.

Inventory Valuation and Reserves

Grain, processed grain, oilseed and processed oilseed are stated at net realizable values which approximate market values. All other inventories are stated at the lower of cost or market. The costs of certain energy inventories (wholesale refined products, crude oil and asphalt) are determined on the last-in, first-out ("LIFO") method; all other inventories of non-grain products purchased for resale are valued on the first-in, first-out ("FIFO") and average cost methods. Estimates are used in determining the net realizable values of grain and oilseed and processed grains and oilseeds inventories. These estimates include the measurement of grain in bins and other storage facilities, which use formulas in addition to actual measurements taken to arrive at appropriate quantity. Other determinations made by management include quality of the inventory and estimates for freight. Grain shrink reserves and other reserves that account for spoilage also affect inventory valuations. If estimates regarding the valuation of inventories, or the adequacy of reserves, are less favorable than management's assumptions, then additional reserves or write-downs of inventories may be required.

Derivative Financial Instruments

We enter into exchange-traded commodity futures and options contracts to hedge our exposure to price fluctuations on energy, grain and oilseed transactions to the extent considered practicable for minimizing risk. Futures and options contracts used for hedging are purchased and sold through regulated commodity exchanges. We also use over-the-counter ("OTC") instruments to hedge our exposure on fixed-price contracts. Fluctuations in inventory valuations, however, may not be completely hedged, due in part to the absence of satisfactory hedging facilities for certain commodities and geographical areas and, in part, to our assessment of our exposure from expected price fluctuations. We also manage our risks by entering into fixed-price purchase contracts with preapproved producers and establishing appropriate limits for individual suppliers. Fixed-price sales contracts are entered into with customers of acceptable creditworthiness, as internally evaluated. The fair values of futures and options contracts are determined primarily from quotes listed on regulated commodity exchanges. Fixed-price purchase and sales contracts are with various counterparties, and the fair values of such contracts are determined from the market price of the underlying product. We are exposed to loss in the event of nonperformance by the counterparties to the contracts and, therefore, contract values are reviewed and adjusted to reflect potential nonperformance. Risk of nonperformance by counterparties includes the inability to perform because of a counterparty's financial condition and also the risk that the counterparty will refuse to perform on a contract during periods of price fluctuations where contract prices are significantly different than the current market prices.

Pension and Other Postretirement Benefits

Pension and other postretirement benefits costs and obligations are dependent on assumptions used in calculating such amounts. These assumptions include discount rates, health care cost trend rates, benefits earned, interest costs, expected return on plan assets, mortality rates and other factors. In accordance with U.S. GAAP, actual results that differ from the assumptions are accumulated and amortized over future periods and, therefore, generally affect recognized expenses and the recorded obligations in future periods. While our management believes that the assumptions used are appropriate, differences in actual experience or changes in assumptions may affect our pension and other postretirement obligations and future expenses.

Deferred Tax Assets and Uncertain Tax Positions

We assess whether a valuation allowance is necessary to reduce our deferred tax assets to the amount that we believe is more likely than not to be realized. While we have considered future taxable income, as well as other factors, in assessing the need for the valuation allowance, in the event that we were to determine that we would not be able to realize all, or part of, our net deferred tax assets in the future, an adjustment to our deferred tax assets would be charged to income in the period such determination was made. We are also significantly impacted by the utilization of tax credits, some of which were passed to us from CHS McPherson (formerly known as NCRA), related to refinery upgrades that enable us to produce ultra-low sulfur fuels. Our tax credit carryforwards are available to offset future federal and state tax liabilities with the tax credits becoming unavailable to us if not used by their expiration date. Our net operating loss carryforwards for tax purposes are available to offset future taxable income. If our loss carryforwards are not used, these loss carryforwards will expire.

Tax benefits related to uncertain tax positions are recognized in our financial statements if it is more likely than not that the position would be sustained upon examination by a tax authority that has full knowledge of all relevant information. The benefits are measured using a cumulative probability approach. Under this approach, we record in our financial statements the greatest amount of tax benefits that have a more than 50% probability of being realized upon final settlement with the tax authorities. In determining these tax benefits, we assign probabilities to a range of outcomes that we feel we could ultimately settle on with the tax authorities using all relevant facts and information available at the reporting date. Due to the complexity of these uncertainties, the ultimate resolution may result in a benefit that is materially different than our current estimate.

Long-Lived Assets

Property, plant and equipment is depreciated or amortized over the expected useful lives of individual or groups of assets based on the straight-line method. Economic circumstances, or other factors, may cause management's estimates of expected useful lives to differ from actual.

All long-lived assets, including property, plant and equipment, goodwill, investments in unconsolidated affiliates and other identifiable intangibles, are evaluated for impairment in accordance with U.S. GAAP, at least annually for goodwill, and whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset or asset group may not be recoverable. For goodwill, our annual impairment testing occurs in our third quarter. An impaired asset is written down to its estimated fair value based on the best information available. Fair value is generally measured by discounting estimated future

cash flows. Considerable management judgment is necessary to estimate discounted future cash flows and may differ from actual.

We have asset retirement obligations with respect to certain of our refineries and other assets due to various legal obligations to clean and/or dispose of the component parts at the time they are retired. In most cases, these assets can be used for extended and indeterminate periods of time, as long as they are properly maintained and/or upgraded. It is our practice and current intent to maintain refineries and related assets and to continue making improvements to those assets based on technological advances. As a result, we believe our refineries and related assets have indeterminate lives for purposes of estimating asset retirement obligations because dates or ranges of dates upon which we would retire a refinery and related assets cannot reasonably be estimated at this time. When a date or range of dates can reasonably be estimated for the retirement of any component part of a refinery or other asset, we will estimate the cost of performing the retirement activities and record a liability for the fair value of that future cost.

We have other assets that we may be obligated to dismantle at the end of corresponding lease terms subject to lessor discretion for which we have recorded asset retirement obligations. Based on our estimates of the timing, cost and probability of removal, these obligations are not material.

Effect of Inflation and Foreign Currency Transactions

We believe that inflation and foreign currency fluctuations have not had a significant effect on our operations during the three years ended August 31, 2015 since we conduct a significant portion of our business in U.S. dollars.

Recent Accounting Pronouncements

In February 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (ASU) No. 2015-02, "Amendments to the Consolidation Analysis." ASU No. 2015-02 amended the process that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. ASU No. 2015-02 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early application is permitted. We are currently evaluating the impact the adoption will have on our consolidated financial statements in fiscal 2017.

In November 2014, the FASB issued ASU No. 2014-16, "Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity." The amendments in this ASU do not change the current criteria in U.S. GAAP for determining when separation of certain embedded derivative features in a hybrid financial instrument is required. The amendments clarify that an entity should consider all relevant terms and features, including the embedded derivative feature being evaluated for bifurcation, in evaluating the nature of the host contract. The ASU applies to all entities that are issuers of, or investors in, hybrid financial instruments that are issued in the form of a share and is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted. The adoption of ASU 2014-16 is not expected to have a material effect on our consolidated financial statements in fiscal 2017.

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." ASU No. 2014-09 requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those good or services. The guidance also requires an entity to disclose sufficient qualitative and quantitative information surrounding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts from customers. This ASU supersedes the revenue recognition requirements in Topic 605, Revenue Recognition and most industry-specific guidance throughout the Industry Topics of the Codification. In August 2015, the FASB issued ASU 2015-14 delaying the effective date for adoption. This update is now effective for annual and interim periods beginning after December 15, 2017, which will require us to adopt these provisions in the first quarter of fiscal 2019. Early application as of the original date is permitted. This update permits the use of either the full or modified retrospective method. We are evaluating the effect this guidance will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.

ITEM 7A.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

COMMODITY PRICE RISK

When we enter into a commodity or freight purchase or sales contract, we incur risks related to price change and performance (including delivery, quality, quantity and counterparty credit). We are exposed to risk of loss in the market value of

positions held, consisting of inventory and purchase contracts at a fixed or partially fixed price in the event market prices decrease. We are also exposed to risk of loss on our fixed or partially fixed price sales contracts in the event market prices increase.

Our hedging activities reduce the effects of price volatility, thereby protecting against adverse short-term price movements, but also limit the benefits of short-term price movements. To reduce the price change risks associated with holding fixed price commitments, we generally take opposite and offsetting positions by entering into commodity futures contracts or options, to the extent practical, in order to arrive at a net commodity position within the formal position limits we have established and deemed prudent for each commodity. These contracts are purchased and sold on regulated commodity futures exchanges for grain, and regulated mercantile exchanges for refined products and crude oil. We also use OTC instruments to hedge our exposure to price fluctuations on commodities and fixed price arrangements. The price risk we encounter for crude oil and most of the grain and oilseed volume we handle can be hedged. Price risk associated with fertilizer and certain grains cannot be hedged with futures because there are no futures for these commodities and, as a result, risk is managed through the use of forward sales contracts and other pricing arrangements and, to some extent, cross-commodity futures hedging. These contracts are economic hedges of price risk, but are not designated as hedging instruments for accounting purposes. The contracts are recorded on our Consolidated Balance Sheets at fair values based on quotes listed on regulated commodity exchanges or are based on the market prices of the underlying products listed on the exchanges, with the exception of certain fertilizer and propane contracts, which are accounted for as normal purchase and normal sales transactions. Unrealized gains and losses on these contracts are recognized in cost of goods sold in our Consolidated Statements of Operations using market-based prices.

When a futures contract is entered into, an initial margin deposit must be sent to the applicable exchange or broker. The amount of the deposit is set by the exchange and varies by commodity. If the market price of a short futures contract increases, then an additional maintenance margin deposit would be required. Similarly, if the price of a long futures contract decreases, a maintenance margin deposit would be required and sent to the applicable exchange. Subsequent price changes could require additional maintenance margins or could result in the return of maintenance margins.

Our policy is to primarily maintain hedged positions in grain and oilseed. Our profitability from operations is primarily derived from margins on products sold and grain merchandised, not from hedging transactions. At any one time, inventory and purchase contracts for delivery to us may be substantial. We have risk management policies and procedures that include net position limits. These limits are defined for each commodity and include both trader and management limits. This policy and computerized procedures in our grain marketing operations require a review by operations management when any trader is outside of position limits and also a review by our senior management if operating areas are outside of position limits. A similar process is used in our energy and wholesale crop nutrients operations. The position limits are reviewed, at least annually, with our management and Board of Directors. We monitor current market conditions and may expand or reduce our net position limits or procedures in response to changes in those conditions. In addition, all purchase and sales contracts are subject to credit approvals and appropriate terms and conditions.

Hedging arrangements do not protect against nonperformance by counterparties to contracts. We primarily use exchange traded instruments, which minimizes our counterparty exposure. We evaluate that exposure by reviewing contracts and adjusting the values to reflect potential nonperformance. Risk of nonperformance by counterparties includes the inability to perform because of a counterparty's financial condition and also the risk that the counterparty will refuse to perform on a contract during periods of price fluctuations where contract prices are significantly different than the current market prices. We manage our risks by entering into fixed price purchase and sales contracts with preapproved producers and by establishing appropriate limits for individual suppliers. Fixed price contracts are entered into with customers of acceptable creditworthiness, as internally evaluated. Historically, we have not experienced significant events of nonperformance on open contracts. Accordingly, we only adjust the estimated fair values of specifically identified contracts for nonperformance. Although we have established policies and procedures, we make no assurances that historical nonperformance experience will carry forward to future periods.

A 10% adverse change in market prices would not materially affect our results of operations, since we use commodity and freight futures and forward contracts as economic hedges of price risk, and since our operations have effective economic hedging requirements as a general business practice.

INTEREST RATE RISK

Debt used to finance inventories and receivables is represented by short-term notes payable, so that our blended interest rate for all such notes approximates current market rates. We have outstanding interest rate swaps with an aggregate notional amount of $420.0 million designated as fair value hedges of portions of our fixed-rate debt. Our objective is to offset changes in the fair value of the debt associated with the risk of variability in the 3-month U.S. Dollar London Interbank Offered Rate ("LIBOR") interest rate, in essence converting the fixed-rate debt to variable-rate debt. Offsetting changes in the fair values of both the swap instruments and the hedged debt are recorded contemporaneously each period and only create an impact to earnings to the extent that the hedge is ineffective. During fiscal 2015 we recorded offsetting fair value adjustments of $8.0 million, with no ineffectiveness recorded in earnings. In fiscal 2015, we entered into forward starting swaps with a notional amount of $300.0 million designated as cash flow hedges of anticipated future issuances of fixed-rate debt. Our objective is to limit the potential cash outflows associated with forecasted debt issuances that are subject to variability in the benchmark interest rates. The swaps expire in fiscal 2016 with no material amounts expected to be included in earnings during the next 12 months.

The table below provides information about our outstanding debt and derivative financial instruments that are sensitive to changes in interest rates. For debt obligations, the table presents scheduled contractual principal payments and related weighted average interest rates for the fiscal years presented. For interest rate swaps, the table presents notional amounts for payments to be exchanged by expected contractual maturity dates for the fiscal years presented and interest rates noted in the table.

_______________________________________

FOREIGN CURRENCY RISK

We conduct a significant portion of our business in U.S. dollars. Our Ag segment continued to expand its international operations in fiscal 2015 with planned future growth. We had minimal, non-material risk regarding foreign currency fluctuations during fiscal 2015 and in prior years, as a substantial amount of international sales were denominated in U.S. dollars. Foreign currency fluctuations do, however, impact the ability of foreign buyers to purchase U.S. agricultural

products and the competitiveness of U.S. agricultural products compared to the same products offered by alternative sources of world supply. From time to time, we enter into foreign currency hedge contracts to mitigate currency fluctuations. The notional amounts of our foreign exchange derivative contracts were $1.3 billion and $784.4 million as of August 31, 2015 and August 31, 2014 , respectively.

ITEM 8.     FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

ITEM 9.     CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A.     CONTROLS AND PROCEDURES

Disclosure of Controls and Procedures:

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) that are designed to provide reasonable assurance that information required to be disclosed by us in the reports we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported, within the time periods specified by the Securities and Exchange Commission's rules and forms and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding disclosure. In designing and evaluating our disclosure procedures, we recognize that any controls and procedures, no matter how well designed and operated can provide only reasonable assurance of achieving the desired control objectives and we necessarily are required to apply our judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Our management evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of the design and operation of our disclosure controls and procedures as of August 31, 2015 . Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that our disclosure controls and procedures were effective, at the reasonable assurance level, as of August 31, 2015 , the end of the period covered in this Annual Report on Form 10-K.

Management's Annual Report on Internal Control Over Financial Reporting:

The financial statements, financial analyses and all other information included in this Annual Report on Form 10-K were prepared by our management, which is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that: pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect our transactions and our disposals of assets; provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition and use or disposal of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the design and operating effectiveness of our internal control over financial reporting as of August 31, 2015 . In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework (2013). Based on management's assessment using this framework, management concluded that, as of August 31, 2015 , our internal control over financial reporting was effective.

This Annual Report on Form 10-K does not include an attestation report of our independent registered public accounting firm regarding internal control over financial reporting. Management's report was not subject to attestation by our independent registered public accounting firm pursuant to the Financial Reform Bill passed in July 2010, that permits us to provide only management's report in this Annual Report on Form 10-K.

Change in Internal Control over Financial Reporting:

During our fourth fiscal quarter, there was no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended) that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

AUDIT COMMITTEE MATTERS

The Board of Directors has a separately designated standing Audit Committee for the purpose of overseeing our accounting and financial reporting processes and audits of our financial statements. The Audit Committee is comprised of Mr. Blew, Mr. Erickson, Mr. Kruger, and Mr. Schurr (Chairman), each of whom is an independent director. The Audit Committee has oversight responsibility to our owners relating to our financial statements and the financial reporting process, preparation of the financial reports and other financial information provided by us to any governmental or regulatory body, the systems of internal accounting and financial controls, the internal audit function and the annual independent audit of our financial statements. The Audit Committee assures that the corporate information gathering and reporting systems developed by management represent a good faith attempt to provide senior management and the Board of Directors with information regarding material acts, events and conditions within CHS. In addition, the Audit Committee is directly responsible for the appointment, compensation and oversight of the independent registered public accounting firm.

We do not believe that any member of the Audit Committee of the Board of Directors is an "audit committee financial expert" as defined in the Sarbanes-Oxley Act of 2002 and the rules and regulations thereunder. As a cooperative, our 17-member Board of Directors is nominated and elected by our members. To ensure geographic representation of our members, the Board of Directors represents eight regions in which our members are located. The members in each region nominate and elect the number of directors for that region as set forth in our bylaws. To be eligible for service as a director, a nominee must (i) be an active farmer or rancher, (ii) be a member of CHS or a Cooperative Association Member and (iii) reside in the geographic region from which he or she is nominated. Neither management nor the incumbent directors have any control over the nominating process for directors. Because of the nomination procedure and the election process, we cannot ensure that an elected director will be an "audit committee financial expert." However, many of our directors, including all of the Audit Committee members, are financially sophisticated and have experience or background in which they have had significant financial oversight responsibilities. The current Audit Committee includes directors who have served as presidents or chairmen of local cooperative association boards. Members of the Board of Directors, including the Audit Committee, also operate large commercial enterprises requiring expertise in all areas of management, including financial oversight.

CHS is an organization that exists to, among other things, help our owners grow. CHS compensation programs are designed to attract, retain and reward the executives who carry out this promise, and align them around attainment of CHS' short and long-term success.

In this section, we will outline the compensation and benefit programs as well as the materials and factors used to assist us in making compensation decisions.

Compensation Philosophy and Objectives

The Governance Committee of our Board of Directors oversees the administration of, and the fundamental changes to, the executive compensation and benefits programs. The primary principles and objectives in compensating executive officers include:

There are no material changes anticipated to our compensation philosophy or objectives for fiscal 2016.

Components of Executive Compensation and Benefits

Our executive compensation programs are designed to attract and retain highly qualified executives and to motivate them to optimize member-owner returns by achieving specified goals. The compensation program links executive compensation directly to our annual and long-term financial performance. A significant portion of each executive's compensation is dependent upon meeting financial goals and a smaller portion is linked to individual performance objectives.

Each year, the Governance Committee of the Board of Directors reviews our executive compensation policies with respect to the correlation between executive compensation and the creation of member-owner value, as well as the competitiveness of the executive compensation programs. The Governance Committee, with input from a third party consultant if necessary, determines what, if any, changes are appropriate to our executive compensation programs including the incentive plan goals for the Named Executive Officers. The third party consultant is chosen and hired directly by the Governance

Committee to provide guidance regarding market competitive levels of base pay, annual variable pay and long-term incentive pay as well as market competitive allocations between base pay, annual variable pay and long-term incentive pay for the Chief Executive Officer (CEO). The data is shared with our Board of Directors which makes final decisions regarding the Chief Executive Officer's base bay, annual incentive pay and long-term incentive pay, as well as the allocation of compensation between base pay, annual incentive pay and long-term incentive pay. There are no formal policies for allocation between long-term and cash compensation other than the intention of being competitive with the external compensation market for comparable positions and being consistent with our compensation philosophy and objectives. The Governance Committee recommends to the Board of Directors salary actions relative to our CEO and approves annual and long-term incentive awards based on goal attainment. In turn, the Board of Directors communicates this pay information to the CEO. The CEO is not involved with the selection of the third party consultant and does not participate in, or observe, Governance Committee meetings that concern CEO compensation matters. Based on a review of compensation market data provided by our human resources department (survey sources and pricing methodology are explained under "Components of Compensation"), with input from a third party consultant if necessary, the CEO decides base compensation levels for the other Named Executive Officers, recommends for Board of Directors approval the annual and long-term incentive levels for the other Named Executive Officers and communicates base and incentive compensation levels to the other Named Executive Officers. The day-to-day design and administration of compensation and benefit plans are managed by our human resources, finance and legal departments.

We intend to preserve the deductibility, under the Internal Revenue Code of 1986, as amended (the Internal Revenue Code), of compensation paid to our executive officers while maintaining compensation programs to attract and retain highly qualified executives in a competitive environment.

In this Compensation Discussion and Analysis, the related compensation tables and the accompanying narratives, all references to a given year refer to our fiscal year ending on August 31 of that year.

Components of Compensation

The executive compensation and benefits program consists of seven components. Each component is designed to be competitive within the executive compensation market. In determining competitive compensation levels, we analyze information from independent compensation surveys, which include information regarding comparable industries, markets, revenues and companies that compete with us for executive talent. The surveys used for this analysis in fiscal 2015 included a combination of any of the following sources: AonHewitt Total Compensation Measurement, Hay Group General Market Executive Report, Mercer Benchmark Database Executive Compensation Survey and Towers Watson CDB Executive Compensation Survey Report. The data extracted from these surveys includes median market rates for base salary, annual incentive, total cash compensation and total direct compensation. Companies included in the surveys vary by industry, revenue and number of employees, and represent both public and private ownership, as well as non-profit, government and mutual organizations. The number of companies participating in these surveys ranged from 446 to 2,592, with an average of 1,056. In addition, in fiscal 2013 we retained Towers Watson to provide customized survey data from the Towers Watson Executive Compensation Databank, to include a subset consisting of 26 companies in the agribusiness, energy, fertilizer and food industries. Data for these companies included 25th, 50th and 75th percentile for base pay, total cash compensation (sum of base pay and annual variable pay), and total direct compensation (sum of base pay, annual variable pay and long-term incentive). Towers Watson also provided historical return on equity data for the same group of agribusiness, energy, fertilizer and food companies. The emphasis of our executive compensation package is weighted more on variable pay through annual variable pay and long-term incentive awards. This is consistent with our compensation philosophy of emphasizing a strong link between pay, employee performance and business goals to foster a clear line-of-sight and strong commitment to CHS' short-term and long-term success, and also aligns our programs with general market practices. The goal is to provide our executives with an overall compensation package that is competitive to compensation in comparable industries, companies and markets. We target the market median for base pay, target total cash and target total direct compensation, and 75th percentile for total direct compensation for above market performance.

The following table presents a more detailed breakout of each compensation element:

Base Pay:

Base salaries of the Named Executive Officers represent a fixed form of compensation paid on a semi-monthly basis. The base salaries are generally set at the median level of market data collected through our benchmarking process against other equivalent positions of comparable companies. The individual's actual salary relative to the market median is based on a number of factors, which include, but are not limited to, scope of responsibilities and individual experience.

Base salaries for the Named Executive Officers are reviewed on an annual basis or at the time of significant changes in scope and level of responsibilities. Changes in base salaries are determined based on review of competitive market data, as well as individual performance and contribution. Changes are not governed by pre-established weighting factors or merit metrics.

The CEO is responsible for this process for the other Named Executive Officers. The Governance Committee is responsible for this process for the CEO. Mr. Casale received a base pay increase of 3.0% effective January 1, 2015. The CHS Board of Directors approved the increase in order to maintain a competitive pay position to market. Each other Named Executive Officer also received a 3.0% base salary increase in fiscal 2015 (other than Mr. McEnroe, who retired on December 31, 2014).

Annual Variable Pay:

Each Named Executive Officer was eligible to participate in our Annual Variable Pay Plan for our year ending August 31, 2015. Target award levels were set with reference to competitive market compensation levels and were intended to motivate our executives by providing variable pay awards for the achievement of predetermined goals. Our incentive program was based on financial performance and specific management business objectives with payout dependent on CHS triggering threshold financial performance. The financial performance components included return on adjusted equity (ROAE) goals for both CHS and the executive's business unit. The CHS threshold, target and maximum ROAE goals for fiscal 2015 were 8%, 10% and 14%, respectively. The threshold, target and maximum ROAE goals for each business unit vary by unit. The management business objectives include individual performance against specific goals such as business profitability, strategic initiatives or talent development.

CHS financial performance goals and award opportunities under our fiscal 2015 Annual Variable Pay Plan were as follows:

The types and relative importance of specific financial and other business goals varies among executives depending upon their positions and the particular business unit for which they are responsible. Financial goals are given greater weight than other individual performance goals in determining individual awards.

The CHS Board of Directors approves the Annual Variable Pay Plan total Company ROAE goals and determines the CEO's individual goals. The weighting of the CEO's goals for fiscal 2015 was 60% CHS total company ROAE, 10% Marketing, General and Administrative Expense as a percent of Gross Profit (MG&A/GP) and 30% principle accountabilities and individual goals. The CEO approves business unit ROAE goals and determines non-financial goals for the other Named Executive Officers. The weighting of goals for the other Named Executive Officers was 70% ROAE and 30% individual goals. The annual variable pay plan is designed such that if threshold non-financial and financial performance goals are achieved, the annual variable pay award would equal 20% of target awards; if target non-financial and financial performance goals are achieved, the award would equal 100% of target awards and if maximum non-financial and financial performance goals are achieved, the award would equal 200% of target awards. Beginning in fiscal 2016, all Named Executive Officers will have the following goal weightings under the Annual Variable Pay Plan: 60% CHS total company ROAE, 10 % MG&A/GP and 30% individual goals.

In conjunction with the annual performance appraisal process of the CEO, the Board of Directors reviews the non-financial goals, and in turn, determines and approves this portion of the annual variable pay award based upon completion or partial completion of the previously specified goals and principal accountabilities for the CEO. Likewise, the CEO uses the same process for determining individual goal attainment for the other Named Executive Officers. Named Executive Officers are covered by the same broad-based Annual Variable Pay Plan as other employees, and based on the plan provisions, when they retire they receive awards prorated to the period of time eligible.

For fiscal 2015, CHS achieved an ROAE of 14.49%. Annual variable pay payments for fiscal 2015 for the Named Executive Officers are as follows:

Profit Sharing:

In fiscal 2015 the maximum ROAE goal was reached.

Effective for fiscal 2016, the ROAE goals are:

Long-Term Incentive Plans:

Each Named Executive Officer is eligible to participate in our Long-Term Incentive Plan ("LTIP"). The purpose of the LTIP is to align results with long-term performance goals, encourage our Named Executive Officers to maximize long-term shareholder value, and retain key executives.

Currently, our LTIP performance measures are based upon our ROAE. In fiscal 2015, we engaged Hay Group to study whether ROAE was the most appropriate performance measure for us to use for our LTIP, or whether there were additional or other performance metrics that would be more appropriate. Hay Group delivered its opinion to us in February that ROAE is an appropriate metric for our LTIP.

The LTIP consists of three-year performance periods to ensure consideration is made for long-term CHS sustainability with a new performance period beginning every year. The LTIP is based on CHS ROAE over three-year periods. The CHS Board of Directors approves the LTIP ROAE goals.

Award opportunities for the fiscal 2013-2015 LTIP are expressed as a percentage of a participant's average salary for the three-year performance period. CHS must meet a three-year period threshold level of ROAE for LTIP to trigger a payout. The threshold, target, maximum and superior performance maximum ROAE goals for the fiscal 2013-2015 performance period were 8%, 10%, 14% and 20%, respectively. Details for fiscal 2015 awards associated with the expanded plan are provided in the fiscal 2015 Grants of Plan-Based Awards table.

Awards from the LTIP are contributed to the CHS Deferred Compensation Plan after the end of each performance period. These awards are earned over a three-year period and vest over an additional 28-month period following the performance period end date. The extended earning and vesting provisions of the LTIP are designed to help CHS retain key executives. Participants who terminate from CHS prior to retirement forfeit all unearned and unvested LTIP award balances. Participants who meet retirement criteria, die or become disabled receive prorated awards following the LTIP plan rules. Like the Annual Variable Pay Plan, award levels for the LTIP are set with regard to competitive considerations.

For the fiscal 2013-2015 performance period, CHS achieved a three year ROAE result of 19.7%. LTIP payments for the fiscal 2013-2015 plan for the Names Executive Officers are as follows:
