TABLE OF CONTENTS

PART I

ITEM 1. BUSINESS

The Company

Apogee Enterprises, Inc. was incorporated under the laws of the State of Minnesota in 1949. The Company believes it is a world leader in certain technologies involving the design and development of value-added glass solutions for enclosing commercial buildings and framing art. Unless the context otherwise requires, the terms "Company," "Apogee," "we," "us" and "our" as used herein refer to Apogee Enterprises, Inc. and its subsidiaries.

The Company is comprised of four reporting segments:

Financial information about the Company's segments and geographic regions can be found in Item 8, Note 15 to the Consolidated Financial Statements of the Company contained elsewhere in this report.

On November 5, 2013, the Company acquired all of the shares of Alumicor Limited (Alumicor). Alumicor's results of operations have been included in the consolidated financial statements and within the Architectural Framing Systems segment since the date of acquisition. For further information, see "Acquisition of Alumicor" below.

Products and Services

Apogee provides distinctive value-added glass solutions for enclosing commercial buildings and framing art. We operate in four segments as described in the following paragraphs.

Architectural Glass, Architectural Services and Architectural Framing Systems Segments

All of these segments participate in various phases of the value chain to design, engineer, manufacture and install customized aluminum and glass window, curtainwall, and storefront and entrance systems for commercial buildings in the non-residential and high-end multi-family construction markets. Through complex processes, we add ultra-thin coatings to uncoated architectural glass to create a variety of aesthetic characteristics and different levels of solar energy management, especially important with the industry trend of increasingly energy-efficient buildings. We also laminate layers of glass and vinyl to create glass that helps protect against hurricanes and bomb blasts. Glass can also be tempered to provide additional strength. In addition, we have the ability to design and build windows, curtainwall, storefront and entrances using our customized aluminum and glass, or glass supplied by others. We also provide finishing services for the metal and plastic components used to frame architectural glass windows and walls and other products. Our installation services allow our customers to meet the timing and cost requirements of their jobs by providing efficiently designed quality window and wall systems and effectively managing the installation of the façade on their building projects.

Our product choices allow architects to create distinctive looks for office towers, hotels, education facilities and dormitories, health care facilities, government buildings, retail centers and multi-family buildings, while meeting functional requirements such as energy efficiency, impact resistance or sound control.

The following table describes the products provided by these segments.

All of the businesses within the Architectural Glass, Architectural Services and Architectural Framing Systems segments manufacture their products to order. Products are shipped to the job site or other location where further assembly or installation may be required by the respective segment's customers.

Large-Scale Optical Technologies (LSO) Segment

The LSO segment provides coated glass and acrylic for use in custom picture framing and fine art applications. The variables in the glass and acrylic used for picture framing products are the size and coatings to give the product UV protection, anti-reflective properties and/or security features. The following table describes the products provided by the LSO segment.

Markets and Distribution Channels

Architectural Glass, Architectural Services and Architectural Framing Systems Segments

The market for architectural products and services is a subset of the construction industry and is differentiated by building type, level of customization required, customers, geographic location and project size. Published market data are not readily available for the market segments that we serve; however, we estimate market size by analyzing overall construction industry data.

Building type - The construction industry is typically segmented into residential construction and non-residential construction, which includes commercial, industrial and institutional construction. Apogee is a leading supplier of architectural glass and metal framing products as well as installation services to the non-residential construction industry. Our products and services are primarily used in commercial buildings (office towers, hotels and retail centers) and institutional buildings (education facilities and dormitories, health care facilities and government buildings), as well as high-end multi-family buildings (a subset of residential construction).

Level of customization - Most projects have some degree of customization, as the end product or service is based on customer-specified requirements for aesthetics and performance, and designed to satisfy local building codes. All of our Architectural Glass, Architectural Services and Architectural Framing Systems businesses are involved in transforming glass, aluminum and other materials to create customized window, curtainwall, storefront and/or entrance systems that meet customer specifications. The only constant is the base materials of the products and the processes we utilize to fabricate, manufacture and/or install the products.

Customers and distribution channels - Our customers and those that influence the projects include architects, building owners, general contractors and glazing subcontractors in the non-residential construction market. Our high-performance architectural glass is marketed using a direct sales force and independent sales representatives. Our installation and renovation services are marketed by a direct sales force, primarily in the metropolitan areas we serve in the United States and also where we have the ability to work with our customers in other U.S. markets. We market our custom and standard windows, curtainwall, storefront and entrance systems using a combination of a direct sales force, independent sales representatives and directly to distributors.

Geographic location - From our domestic glass fabrication locations, we supply products primarily to the U.S. market, with some international distribution of our high-performance architectural glass. We estimate the U.S. market for architectural glass fabrication in non-residential buildings is approximately $1.1 billion in annual sales. From our Brazilian glass fabrication facility, we primarily supply architectural glass to the Brazilian market, which we estimate to be approximately $0.4 billion in annual sales. Our aluminum framing systems, including windows, curtainwall, storefront and entrances, are marketed in North America, where we estimate the market size is approximately $2.5 billion in annual sales.

We estimate the U.S. market for installation services is approximately $7.5 billion in annual sales. Within the installation services market, Apogee is one of only a few companies to have a national presence, with 11 offices and satellite offices serving multiple U.S. markets. We estimate that we are able to serve, from our existing locations and our ability to travel to other markets where we do not have a local presence, approximately 60 percent of the total installation market. Although installation of building glass in new commercial and institutional construction projects is the primary focus of our business, we also offer installation retrofits or renovations for the outside skin of older commercial and institutional buildings.

Project size - The projects on which our Architectural Glass, Architectural Services and Architectural Framing Systems segments bid and work vary in size. Our high-performance architectural glass fabrication products serve mid-size to monumental high-profile projects. Our Architectural Services and Architectural Framing Systems segments target mid-size projects.

LSO Segment

The Company's Tru Vue brand is the largest domestically manufactured brand for value-added glass and acrylic for the custom picture framing market. Under this brand, products are distributed primarily in North America through independent distributors, which supply national and regional chains and local picture framing shops, as well as through national retailers. The Company has also been successful in supplying products to museums and public and private galleries. We also have distribution in Europe and selected other international markets through independent distributors; we view this as a focus area for future growth of this segment.

Through the Company's leadership, the custom picture framing industry continues to convert from clear glass to value-added picture framing glass and acrylic, a trend that is expected to continue and has helped the Company offset market softness over the past several years. We believe that we have a majority share of demand for the U.S. value-added custom picture framing glass market segment.

Warranties

We offer product and service warranties which we believe are competitive for the markets in which our products and services are sold. The nature and extent of these warranties depend upon the product or service, the market and, in some cases, the customer being served. Our standard warranties are generally from two to 10 years for our architectural glass, curtainwall and window system products, while we generally offer warranties of two years or less on our other products and installation services. In the event of a claim against a product for which we have received a warranty from the supplier, we pass the claim back to our supplier. Although we carry liability insurance with very high deductibles for product failures, we reserve for warranty exposures, as our insurance does not cover warranty claims. There can be no assurance that our insurance will be sufficient to cover all product failure claims in the future; that the costs of this insurance and the related deductibles will not increase materially; or that liability insurance for product failures will be available on terms acceptable to the Company in the future.

Sources and Availability of Raw Materials

Materials used within the Architectural Glass and Architectural Framing Systems segments include raw glass, aluminum billet and extrusions, vinyl, metal targets, insulated glass spacer frames, silicone, plastic extrusions, desiccant, chemicals, paints, lumber and urethane. Within the Architectural Services segment, materials used include fabricated glass, aluminum extrusions, silicone, plastic extrusions and fabricated metal panels. The LSO segment uses glass, hard-coated acrylic, acrylic substrates, coating materials and chemicals.

Glass manufacturers have applied surcharges to the cost of glass over the past several years to help offset increases in energy and fuel costs, which we are generally able to pass on to our customers through surcharges. We have also seen recent volatility in the

cost and supply of aluminum that is used in our window, storefront, entrance and curtainwall systems. Where applicable, we have passed the changes in cost of materials on to our customers in the form of pricing adjustments and/or surcharges.

A majority of our raw materials are readily available from a variety of domestic and international sources, and no supplier delays or shortages are anticipated. While certain glass products may only be available at certain times of the year, all standard glass types and colors are available throughout the year in reasonable quantities from multiple suppliers.

Trademarks and Patents

The Company has several trademarks and trade names that we believe have significant value in the marketing of our products, including APOGEE ® . Trademark registrations in the United States are generally for a term of 10 years, renewable every 10 years as long as the trademark is used in the regular course of trade.

Within the Architectural Glass segment, VIRACON ® , VIRACON VUE-50 ® and STORMGUARD ® are registered trademarks. DIGITALDISTINCTIONS™, ROOMSIDE™, EXTREMEDGE™, GLASS IS EVERYTHING™, BUILDING DESIGN™, VIRASPAN™, CLEAR POINT™ and CYBERSHIELD™ are unregistered trademarks. In addition, GLASSEC ® , INSULATTO ® and BLINDATTO ® are registered trademarks in Brazil.

Within the Architectural Services segment, HARMON GLASS ® , HI - 5000 ® and HI - 7000 ® are registered trademarks. HARMON™ and INNOVATIVE FACADES SOLUTIONS™ are unregistered trademarks.

Within the Architectural Framing Systems segment, LINETEC ® , WAUSAU WINDOW AND WALL SYSTEMS ® , TUBELITE ® , ADVANTAGE BY WAUSAU ® , FINISHER OF CHOICE ® , THERML=BLOCK ® , MAXBLOCK ® , DFG ® , ECOLUMINUM ® , ALUMINATE ® , GET THE POINT! ® and FORCEFRONT ® are registered trademarks. ALUMICOR™ and BUILDING EXCELLENCE TM are unregistered trademarks in Canada.

Within the LSO segment, TRU VUE ® , CONSERVATION CLEAR ® , CONSERVATION MASTERPIECE ACRYLIC ® , CONSERVATION REFLECTION CONTROL ® , ULTRAVUE ® , MUSEUM GLASS ® , OPTIUM ® , PREMIUM CLEAN ® , REFLECTION CONTROL ® , AR REFLECTION - FREE ® , TRU VUE AR ® , OPTIUM ACRYLIC ® , OPTIUM MUSEUM ACRYLIC ® and CONSERVATION MASTERPIECE ® are registered trademarks. STATICSHIELD™ is an unregistered trademark.

The Company has several patents pertaining to our glass coating methods and products, including our UV coating and etch processes for anti-reflective glass for the picture framing industry. Despite being a point of differentiation from its competitors, no single patent is considered to be material to the Company.

Seasonality

The North American businesses in our Architectural Glass, Architectural Services and Architectural Framing Systems segments experience a slight seasonal effect following the domestic commercial construction industry, with higher demand from May through December. Our Brazilian Architectural Glass segment business does not have a significant seasonal trend. A bigger impact to net sales is the fact that the construction industry is highly cyclical in nature and can be influenced differently by the effects of the localized economy in geographic markets.

Within the LSO segment, picture framing glass sales tend to increase in the September to December timeframe. However, the timing of customer promotional activities may offset some of this seasonal impact.

Working Capital Requirements

Trade accounts receivable is the largest component of working capital for the Company, including receivables relating to contractual retention amounts that can be outstanding throughout the project duration within the Architectural Services segment. Payment terms offered to our customers are similar to those offered by others in the industry. For the Architectural Glass and Architectural Framing Systems segments, inventory requirements are not significant since these businesses make-to-order rather than build-to-stock for the majority of their products. As a result, inventory levels follow customer demand for the products produced.

Since the LSO segment builds-to-stock for the majority of its products, it requires greater inventory levels to meet the demands of its customers.

Dependence on a Single Customer

We do not have any one customer that exceeds 10 percent of the Company's consolidated net sales. However, there are important customers within each of our segments; the loss of one or more customers could have an adverse effect on the Company.

Backlog

Backlog represents the dollar amount of revenues we expect to recognize in the future from firm contracts or orders received, as well as those that are in progress. Backlog is not a term defined under generally accepted accounting principles and is not a measure of contract profitability. We include a project within our backlog at the time a signed contract or a firm purchase order is received, generally as a result of a competitive bidding process. Backlog by reporting segment at March 1, 2014 and March 2, 2013 was as follows:

We expect approximately $314.5 million , or 95 percent , of our March 1, 2014 backlog to be recognized in fiscal 2015 , with the balance to be recognized in fiscal 2016 and beyond. We view backlog as an important statistic in evaluating the level of sales activity and short-term sales trends in our business. However, as backlog is only one indicator, and is not an effective indicator of our ultimate profitability, we do not believe that backlog should be used as the sole indicator of future earnings of the Company.

Competitive Conditions

Architectural Glass, Architectural Services and Architectural Framing Systems segments

The markets served by the Architectural Glass, Architectural Services and Architectural Framing Systems segments are very competitive, are price and lead-time sensitive, and are primarily affected by changes in the North American commercial construction industry as well as changes in general economic conditions. Additionally, due to the Architectural Glass segment's operations in Brazil, it is impacted by the commercial construction industry and general economic conditions found in Brazil and the immediate region.

Interest rates, credit availability for commercial construction projects, material costs, employment rates, office vacancy rates, building construction starts and office absorption rates are key indicators to the commercial construction market conditions. As each of these economic indicators moves favorably, our businesses typically experience sales growth, and vice-versa.

These segments primarily serve the custom portion of the commercial construction market, which is generally highly fragmented. The primary competitive factors are price, product quality, reliable service, on-time delivery, warranty and the ability to provide technical engineering and design services. There is potential to offset some competitive pressures through increased renovation of the exteriors of commercial and institutional buildings using some of our segments' products and services due to their premium energy-efficiency properties.

We believe that our competition does not provide the same level of custom coatings to the market as our Architectural Glass segment, but regional glass fabricators can provide somewhat similar products with similar attributes. Regional glass fabricators incorporate high performance, post-temperable glass products, procured from primary glass suppliers, into their insulated glass products. The availability of these products has enabled regional glass fabricators in some cases to bid on more complex projects than in the past. Since we typically target the more complex projects, we have encountered increased competition from these regional glass fabricators. In certain regions of the U.S., we encounter competition from international competitors on complex projects.

When providing glass installation and services, our Architectural Services segment largely competes against regional and local construction companies and installation contractors, and periodically against other larger national companies.

The commercial window and storefront manufacturing market is highly fragmented and our Architectural Framing Systems segment competes against several major aluminum window and storefront manufacturers in various market niches. With window products at the high-end of the performance scale and one of the industry's best standard window warranties for repair or replacement of defective product, we effectively leverage a reputation for engineering quality and delivery dependability into a position as a preferred provider for high-performance products. Within the architectural finishing market, we compete against regional paint and anodizing companies.

Our businesses in the Architectural Glass, Architectural Services and Architectural Framing Systems segments maintain significant relationships with architects, who influence the selection of products and services on a project. Additionally, throughout a construction project, the Architectural Services segment must maintain significant relationships with general contractors, who are the segment's direct customers. This is due to the high degree of dependence on general contractors and architects for project initiation and development of specifications. Additionally, the timing of a project depends on the schedule established by the general contractors and their ability to maintain this schedule. If a general contractor fails to keep a construction project on its established timeline, the timing and profitability of the project could be negatively impacted.

LSO Segment

Product attributes, pricing, quality, marketing, and marketing services and support are the primary competitive factors in the markets within the LSO segment. The Company's competitive strengths include our excellent relationships with customers and the performance provided by our unique value-added products. While there is significant price sensitivity in regard to sales of clear glass to picture framers, there is somewhat less price sensitivity on certain of our value-added glass products due to their unique attributes. There is competition in North America with European imports of certain valued-added products for picture framing.

Research and Development

The amount spent on research and development activities was $7.8 million , $6.8 million and $7.2 million in fiscal 2014 , 2013 and 2012 , respectively. Of this amount, $2.1 million , $1.6 million and $0.8 million , respectively, was focused primarily upon design of custom window and curtainwall systems in accordance with customer specifications and is included in cost of sales in the accompanying consolidated financial statements.

Environment

We use hazardous materials in our manufacturing operations, and have air and water emissions that require controls. As a result, we are subject to stringent federal, state and local regulations governing the storage, use and disposal of wastes. We contract with outside vendors to collect and dispose of waste at our production facilities in compliance with applicable environmental laws. In addition, we have procedures in place that we believe enable us to properly manage the regulated materials used in our manufacturing processes and wastes created by the production processes, and we have implemented a program to monitor our compliance with environmental laws and regulations. Although we believe we are currently in material compliance with such laws and regulations, current or future laws and regulations could require us to make substantial expenditures for compliance with chemical exposure, waste treatment or disposal regulations. We spent approximately $0.5 million , $0.1 million and $0.2 million in fiscal 2014 , 2013 and 2012 , respectively, to reduce wastewater solids and hazardous air emissions at our facilities. We expect to incur costs to continue to comply with laws and regulations in the future for our ongoing manufacturing operations but do not expect these to be material to our financial statements.

As part of the acquisition of Tubelite Inc. (Tubelite) on December 21, 2007, we acquired a manufacturing facility which has historical environmental conditions. We believe that Tubelite is a "responsible party" for certain of these historical environmental conditions, and the Company intends to remediate those conditions. The Company believes the remediation activities can be conducted without significant disruption to manufacturing operations at this facility. As of March 1, 2014 , the environmental reserve balance was $1.5 million .

Employees

The Company employed 4,266 and 3,871 persons on March 1, 2014 and March 2, 2013 , respectively. At March 1, 2014 , 432 of these employees were represented by U.S. labor unions and 336 of these employees were represented by labor unions in Brazil.

Acquisition of Alumicor

On November 5, 2013, the Company acquired all of the shares of Alumicor Limited, a privately held business, for $52.9 million , including cash acquired of $1.6 million . Alumicor is a window, storefront, entrance and curtainwall company primarily serving the Canadian commercial construction market. Alumicor's results of operations have been included in the consolidated financial statements and within the Architectural Framing Systems segment since the date of acquisition. Item 8, Note 6 of the Notes to the Consolidated Financial Statements contains further information regarding this acquisition.

Foreign Operations and Export Sales

During the years ended March 1, 2014 , March 2, 2013 and March 3, 2012 , the Company's export sales from domestic operations, principally from sales of architectural glass, amounted to approximately $52.5 million , $63.5 million and $75.7 million , respectively, or 7 percent of net sales in fiscal 2014 , 9 percent of net sales in fiscal 2013 , and 11 percent of net sales in fiscal 2012 . Consolidated net sales for fiscal 2014 , 2013 and 2012 include GlassecViracon sales of $36.7 million , $32.0 million and $34.1 million , respectively, or five percent of net sales in each of fiscal 2014 , 2013 and 2012 , all of which were non-U.S. sales. Consolidated net sales for fiscal 2014 included Alumicor sales of $15.9 million or 2 percent of net sales in fiscal 2014 , all of which were non-U.S. sales.

ITEM 1A. RISK FACTORS

Our business faces many risks. Any of the risks discussed below, or elsewhere in the Form 10-K or our other filings with the Securities and Exchange Commission, could have a material adverse impact on our business, financial condition or results of operations.

Operational Risks

General global economic and business conditions could negatively affect our results.

Our Architectural Glass, Architectural Services and Architectural Framing Systems segments are dependent on global economic conditions and the cyclical nature of the North American commercial construction industry. The commercial construction market is impacted negatively by volatility in global financial markets, including, among other things, volatility in securities prices, availability of credit, unemployment rates, consumer confidence, interest rates and commodity prices. To the extent changes in these factors negatively impact the overall commercial construction market, our revenue and profits could be significantly reduced.

Our Architectural Glass segment's operation located in Brazil is subject to the economic, political and tax conditions prevalent in the region. The economic conditions in this region are subject to different growth expectations, market weaknesses and business practices than seen in the U.S. market. We cannot predict how changing market conditions in this region will impact our financial results.

Our LSO segment depends on the strength of the retail picture framing market. This market is highly dependent on consumer confidence and the conditions of the U.S. economy. If consumer confidence declines, whether as a result of an economic slowdown, uncertainty regarding the future or other factors, our use of these strategies may not be as successful in the future, resulting in a potential decrease in net sales and operating income.

New market entrants or specific actions of our competitors could adversely impact our market position and future results.

All of our operating segments operate in competitive markets where the actions of competitors or new market entrants could result in a loss of customers or share of customers' purchases. Additionally, changes in our competitors' products, prices or services could negatively impact our market share, net sales or margins.

Our Architectural Glass and Architectural Framing Systems segments have seen an increase in imports of competitive products from lower-cost, international suppliers that, if this were to continue, could negatively impact our net sales and margins. Our LSO segment competes with several international specialty glass manufacturers that have traditionally not penetrated the domestic core markets served. Although these LSO competitors have not been able to meet the specification level of our products, upgrades to our competitor's products could have a negative impact on net sales or margins.

Our ability to effectively utilize our manufacturing capacity could adversely impact future results.

Near-term performance depends, to a significant degree, on our ability to utilize available production capacity. The failure to successfully utilize or manage capacity, the impact of closing a facility in the future, or re-opening a currently closed facility, could adversely affect our operating results. Additionally, advances in product or process technologies on the part of existing or prospective competitors could have a significant impact on our ability to utilize our capacity and, therefore, have an adverse impact on our net sales and operating results.

Product quality issues could negatively impact demand for our products and future profitability.

We manufacture and/or install a significant portion of our products based on specific requirements of each customer. We believe that future orders of our products or services will depend on our ability to maintain the performance, reliability and quality standards required by our customers. If our products or services have performance, reliability or quality problems, or products are installed using incompatible glazing materials or installed improperly, we may experience additional warranty and service expense; reduced or canceled orders; diminished pricing power; higher manufacturing or installation costs; or delays in the collection of accounts receivable. Additionally, performance, reliability or quality claims from our customers, with or without merit, could result in costly and time-consuming litigation that could require significant time and attention of management and involve significant monetary damages that could negatively impact our financial results.

Project management and installation issues could negatively impact future results.

The Architectural Services segment is typically awarded fixed-price contracts for installation services. Often, bids are required before all aspects of a construction project are known. An underestimate in the amount of labor required and/or cost of materials for a project; a change in the timing of the delivery of product; difficulties or errors in execution; use of incompatible glazing materials; or significant project delays, caused by us or other trades, could result in failure to achieve the expected results. Any such issues could result in losses on individual contracts that could impact our operating results.

Our future profitability and cash flow are dependent on realizing expected government incentives.

We have made commitments to expand certain manufacturing facilities and make investments in new manufacturing capabilities. Contributing to the decision to make such investments was the availability of federal, state and local incentives including tax credits, tax increment financing and grants. If the Company is not able to realize the benefits of planned incentive packages, future operating results could be negatively impacted.

A shift in consumer preferences could negatively impact the demand for our products.

Any change in customer preference, architectural trends or building codes that reduces window-to-wall ratios in non-residential construction would negatively impact net sales and operating income in our Architectural Glass, Architectural Services and Architectural Framing Systems segments. The LSO segment depends on U.S. consumers framing art and other decorative items. Any shift in customer preference away from framed art to other forms of decorative media could negatively impact future net sales and operating income in the LSO segment.

The loss of a significant customer in the LSO segment could adversely affect our results.

The LSO segment is highly dependent on a relatively small number of customers for its sales. We expect to continue deriving a significant portion of our net sales from a small number of customers. Accordingly, loss of a significant customer or a significant reduction in pricing, or a shift to a less favorable mix of value-added picture framing glass or acrylic products for one of those customers could materially reduce LSO net sales and operating results.

The Architectural Framing Systems results could be adversely impacted by integration and other uncertainties associated with the acquisition of an operation outside of the United States.

The Architectural Framing Systems segment's near-term performance is influenced by its ability to successfully integrate the recently acquired business in Canada. If we are unable to successfully integrate the business into our current business model, or do not realize projected efficiencies and cost-savings from the business we acquired, we may be unable to meet our growth or profit objectives. Additionally, our increased presence outside the U.S. makes our revenues and net income subject to the volatility of exchange rates and the economic, political and tax conditions prevalent in the region.

Our results can be volatile and differ significantly from our expectations and the expectations of analysts.

Our net sales and operating results may differ from Company-provided guidance and the expectations of securities analysts or investors in future periods. Our annual net sales and operating results may vary depending on a number of factors, including, but not limited to, fluctuating customer demand, delay or timing of shipments, construction delays or cancellations due to lack of financing for construction projects, changes in product and project mix or market acceptance of new products. Manufacturing or operational difficulties that may arise due to quality control, capacity utilization of our production equipment or staffing requirements may also adversely impact our annual net sales and operating results. In addition, competition, including new entrants into our markets, the introduction of new products by competitors, adoption of competitive technologies by our customers, or competitive pressures on prices of our products and services, could adversely impact our annual net sales and operating results. Finally, our annual net sales and operating results may vary depending on raw material pricing and the potential for disruption of supply, or changes in legislation that could have an adverse impact on our labor or other costs. Our failure to meet net sales and operating result expectations would likely adversely affect the market price of our common stock.

We retain significant risk through self-insurance programs.

We obtain third-party insurance for potential losses from general liability, employment practices, workers' compensation and automobile liability risk. However, a high amount of risk is retained on a self-insured basis through a wholly-owned insurance subsidiary. Therefore, a material product liability event, such as a material rework event, could have a material adverse effect on our operating results.

We use hazardous chemicals in the production of our products and are thus subjected to changes in environmental legislation.

We use hazardous chemicals in producing our products. One of our facilities has certain historical environmental conditions that we believe require remediation. Our inability to remediate the historical environmental conditions at the facility at or below the amounts reserved, therefore, could have a material adverse impact on future financial results. Additionally, we are subject to a variety of local, state and federal governmental regulations relating to storage, discharge, handling, emission, generation and disposal of toxic or other hazardous substances used to manufacture our products, compliance with which is expensive. Our failure to comply with current or future environmental regulations could result in the imposition of substantial fines on us, suspension of production, alteration of our manufacturing processes or increased costs. Our financial results could also be adversely impacted by rising energy and material costs associated with environmental regulations.

A loss of key personnel could negatively impact near-term results.

Our success depends on the skills, experience and efforts of our executive management and other key personnel. If, for any reason, one or more senior executives or key personnel were not to remain active in our Company, our financial results could be adversely affected.

ITEM 2. PROPERTIES

The following table lists, by segment, the Company's major facilities as of March 1, 2014 , the general use of the facility and whether it is owned or leased by the Company.

In addition to the locations listed above, the Architectural Services segment business operates 11 leased locations, serving multiple markets.

One of the Viracon facilities, a portion of the Wausau Window and Wall Systems facility, a portion of the Linetec facility and the Tru Vue facilities were constructed with the use of proceeds from industrial revenue bonds issued by their applicable cities. These properties are considered owned since, at the end of the bond term, title reverts to the Company.

ITEM 3. LEGAL PROCEEDINGS

The Company has been a party to various legal proceedings incidental to its normal operating activities. In particular, like others in the construction supply and services industry, the Company's construction supply and services businesses are routinely involved in various disputes and claims arising out of construction projects, sometimes involving significant monetary damages or product replacement. The Company has also been subject to litigation arising out of employment practices, workers' compensation, general liability and automobile claims. Although it is very difficult to accurately predict the outcome of such proceedings, facts currently

available indicate that no such claims will result in losses that would have a material adverse effect on the results of operations, cash flows or financial condition of the Company.

Overview

We are a leader in certain technologies and distinctive solutions for enclosing commercial buildings and framing art. The Company's four reportable segments are: Architectural Glass, Architectural Services, Architectural Framing Systems and Large-Scale Optical (LSO). Our Architectural Glass segment consists of Viracon, a fabricator of coated, high-performance architectural glass for global markets. The Architectural Services segment consists of Harmon, one of the largest U.S. full-service building glass installation and renovation companies, which designs, engineers, fabricates and installs the walls of glass, windows and other curtainwall products making up the outside skin of commercial and institutional buildings. The Architectural Framing Systems segment companies design, engineer, fabricate and finish the aluminum frames used in customized aluminum and glass window, curtainwall, storefront and entrance systems comprising the outside skin and entrances of commercial and institutional buildings. We have aggregated four operating segments into the Architectural Framing Systems reporting segment based upon their similar products, customers, distribution methods, production processes and economic characteristics: Wausau Window and Wall Systems, a manufacturer of standard and custom aluminum window systems and curtainwall for the North American commercial construction and historical renovation markets; Tubelite, a fabricator of aluminum storefront, entrance and curtainwall products for the U.S. commercial construction industry; Alumicor, a fabricator of aluminum storefront, entrance, curtainwall and window products for the Canadian commercial construction industry; and Linetec, a paint and anodize finisher of architectural aluminum and PVC shutters for U.S. markets. Our LSO segment consists of Tru Vue, a manufacturer of value-added glass and acrylic for the custom picture framing and fine art markets.

The following highlights the results for fiscal 2014 :

Strategy

Architectural Glass, Architectural Services and Architectural Framing Systems Segments

All of these segments serve the commercial construction market, which is highly cyclical. They participate in various phases of the value chain to design, engineer, manufacture and install customized aluminum and glass window, curtainwall, and storefront and entrance systems for commercial buildings - each with nationally recognized brands and leading positions in their target market segments.

The window, curtainwall and storefront systems manufactured by our Architectural Framing Systems segment, as well as the glass products fabricated by our Architectural Glass segment, are sold to installers who enclose commercial buildings, such as offices, hospitals, educational facilities, government facilities, high-end multi-family buildings and retail centers. We believe general

contractors and architects value our ability to reliably deliver quality, customized window and curtainwall solutions. Their customers - building owners and developers - value the distinctive look, energy efficiency, and hurricane and blast protection features of our window and curtainwall systems. These attributes can contribute to higher lease rates, lower operating costs due to the energy efficiency of our value-added glass, a more comfortable environment for building occupants, and protection for buildings and occupants from hurricanes and blasts.

Our Architectural Services segment provides services to fabricate and install glass window and curtainwall systems on newly constructed commercial buildings as well as providing large-scale retrofit services for the window and curtainwall systems on existing commercial buildings. We collaborate closely with our customers, the general contractors, to complete installation projects on time and on budget in order to minimize costly job-site labor overruns.

We look at several market indicators, such as office space vacancy rates, architectural billing statistics, employment and other macroeconomic indicators, to gain insight into the commercial construction market. One of our primary indicators is U.S. non-residential construction market activity as documented by McGraw-Hill Construction (McGraw-Hill), a leading independent provider of construction industry analysis, forecasts and trends. We utilize the information for the building types that we typically serve (office towers, hotels, retail centers, education facilities and dormitories, health care facilities, government buildings and high-end multi-family buildings) and adjust this information (which is based on construction starts) to align with our fiscal year and the lag that is required to account for when our products and services typically are initiated in a construction project - approximately eight months after project start. From the McGraw-Hill data, we believe that our U.S. markets had a compound annual growth rate of 4 percent over our past three fiscal years, while our combined architectural segments' domestic compound annual growth rate was 11 percent over that same period.

Our overall strategy in these segments is to deliver organic growth faster than our commercial construction markets. This organic growth is accomplished through geographic expansion and entry into adjacent markets, while remaining focused on distinctive solutions for enclosing commercial buildings. We draw upon our leading brands, energy-efficient products and reputation for high quality and service in pursuit of our strategies. We also aspire to lead our markets in the development of practical, energy-efficient products for new construction and renovation. We have introduced products and services designed to meet the growing demand for energy-efficient building materials. These products have included new energy-efficient glass coatings, thermally enhanced aluminum framing systems, and systems with a high percentage of recycled content.

While each of our operating segments has the ability to grow through geographic expansion and product line extension, we regularly evaluate business development opportunities in complementary markets. This strategy can take the form of acquisition or strategic alliances. Through our acquisitions completed in fiscal 2014, we have entered the Canadian market for storefront and entrance systems and expanded our product offerings for the historically accurate window renovation market.

In recent years, we have increased our focus on the window and curtainwall retrofit and renovation market. We have seen increased interest from all sectors of the non-residential and high-end multi-family building markets in upgrading the façades and improving the energy efficiency of their buildings. We consider this to be a significant opportunity for Apogee in the coming years.

Additionally, we are constantly working to improve the efficiency and productivity of our manufacturing and installation operations. During fiscal 2014, we completed the initial roll-out of lean manufacturing principles to all of our operating units and expect to continue to see gross margin expansion due to improved manufacturing productivity.

Lastly, we consistently evaluate capital investments to improve productivity and product development capabilities, as well as to provide appropriate manufacturing capacity to support growth.

LSO segment

Our basic strategy in this segment is to convert the custom picture framing market from clear uncoated glass and acrylic products to value-added products that protect art from UV damage while minimizing reflection from the glass, so that viewers see the art rather than the glass. We estimate that over 60 percent of the U.S. picture framing market has converted to value-added glass. Although we are finding it more difficult to convert the remaining U.S. market, we continue to see conversion in the market. We offer a variety of products with varying levels of reflection control and promote the benefits to consumers with point-of-purchase displays and other promotional materials.

We also participate in the global fine art market, which includes demand from museums and private art collections. This market appreciates the conservation and anti-reflective properties of our products, primarily our acrylic products. Acrylic is a preferred material in the fine art market because the product is light weight, which allows its use with art that is much larger and for which weight is an important consideration. We will continue to expand our presence in this market through international expansion and product line extensions.

Additionally, we have continued to execute our strategy of expanding into custom picture framing markets outside the U.S. Over the past three years, we have focused on the European markets. In fiscal 2012, we opened up a warehouse in the Netherlands and began selling our custom picture framing glass and acrylic in Europe where, historically, we have had very little presence. We developed new products and marketing materials for this market and have distributors in over10 countries. We believe our products and distribution will enable us to grow at a faster pace internationally than in the United States.

Results of Operations

Net Sales

Fiscal 2014 Compared to Fiscal 2013

Sales grew 10.2 percent in fiscal 2014 to $771.4 million compared to $700.2 million in fiscal 2013. The inclusion of Alumicor sales since the date of acquisition accounted for 2 percentage points of this increase. Improved product mix and pricing in the Architectural Glass segment drove approximately 4 percentage points of the increase. Volume growth in the Architectural Services segment favorably impacted the year by about 2 percentage points and the remainder of the increase resulted from improved volume in our Architectural Framing segment's U.S. storefront and finishing businesses.

Fiscal 2013 Compared to Fiscal 2012

Sales increased 5.7 percent during fiscal 2013 largely due to share gains through domestic geographic expansion and increased penetration in target markets in the Architectural Services and Architectural Framing Systems segments, representing approximately 4 percentage points of the increase. Improved pricing in the Architectural Glass segment also had a favorable impact on fiscal 2013 revenues, representing another approximately 4 percentage points of the increase over fiscal 2012. Fiscal 2013 included 52 weeks compared to 53-weeks in fiscal 2012, which had a negative impact of approximately 2 percentage points on fiscal 2013 sales.

Performance

The relationship between various components of operations, as a percentage of net sales, is illustrated below for the past three fiscal years.

Fiscal 2014 Compared to Fiscal 2013

Gross profit improved as a percent of sales to 21.4 percent in fiscal 2014 from 20.8 percent in fiscal 2013. The improvement in gross margins was due to the margin impact of improved mix and pricing in the Architectural Glass segment, improved project margins in the Architectural Services segment and overall productivity improvements. These favorable items were partially offset by lower capacity utilization in the Architectural Framing System's window business related to an anticipated gap in the schedule for more complex projects.

Selling, general and administrative (SG&A) spending increased by $6.7 million in fiscal 2014 over fiscal 2013, while SG&A as a percent of sales decreased to 16.2 percent in fiscal 2014 from 16.9 percent in fiscal 2013. The increase in spending was primarily due to increased salaries and related benefits to support sales growth and geographic expansion, as well as other costs related to geographic expansion and acquisitions.

Fiscal 2013 Compared to Fiscal 2012

Gross profit was up 3.1 percentage points in fiscal 2013 as compared to fiscal 2012 due to improved pricing in the Architectural Glass segment, productivity improvements across all segments, and the margin impact from the revenue growth in the Architectural Services and Architectural Framing Systems segments. In addition, fiscal 2013 benefited from completing higher margin work and positive project execution in the Architectural Services segment.

Selling, general and administrative expenses decreased as a percent of sales to 16.9 percent in fiscal 2013 from 17.1 percent in fiscal 2012, while spending was up $5.0 million. The increase in spending was primarily due to increased expense for incentive compensation programs, as Company operating performance improved. This was partially offset by a decrease in costs related to the Chief Executive Officer transition that were included in fiscal 2012 SG&A expenses.

Fiscal 2013 income tax expense returned to normal levels as compared to fiscal 2012, which included tax benefits from credits and deductions on a low base of earnings and the impact of statute of limitation expirations for prior fiscal years.

Segment Analysis

Architectural Glass

Fiscal 2014 Compared to Fiscal 2013. Fiscal 2014 net sales increased $27.4 million to $293.8 million, or 10.3 percent over fiscal 2013. Improved mix and pricing in our U.S. and Brazilian businesses accounted for approximately 8 percentage points of the increase. The remainder was due to volume growth in both our U.S. and Brazilian businesses, partially offset by a decline in our export volume.

Operating income of $3.9 million in fiscal 2014 was an $8.3 million improvement over the fiscal 2013 loss of $4.4 million. Operating margins improved to 1.3 percent in fiscal 2014 compared to negative 1.6 percent in fiscal 2013. The improvement in operating results was largely due to the impact of a better mix of higher value-added projects and improved pricing. The impact of volume growth and productivity improvements also contributed to the year-on-year increase in operating results.

Fiscal 2013 Compared to Fiscal 2012. Fiscal 2013 net sales decreased $11.6 million or 4.2 percent from fiscal 2012. Revenues were down 13 percentage points attributable to volume decreases, partially offset by a 9 percentage point increase in net sales from improved pricing. The volume declines were largely due to a planned decline in export sales as we focused on more profitable domestic projects, as well as the impact of exchange rates on our Brazilian business.

For fiscal 2013, the segment incurred an operating loss of $4.4 million, with an operating margin of negative 1.6 percent, compared to an operating loss of $19.6 million and a negative operating margin of 7.0 percent in fiscal 2012. The fiscal 2013 improvement was primarily due to improved pricing, a better mix of business, and improved operating performance and management of fixed costs.

Architectural Services

Fiscal 2014 Compared to Fiscal 2013. Fiscal 2014 net sales increased $16.8 million over fiscal 2013, a 9.0 percent increase. Volume growth in existing and expanded geographies was the driver of this growth. Fiscal 2014 operating income increased $5.5 million to $4.5 million compared to a loss of $1.0 million in fiscal 2013. Operating margin of 2.2 percent in fiscal 2014 was an improvement of 2.7 percentage points over fiscal 2013. The improved operating results were a result of better project margins, as we have worked through lower margin projects that were bid in the bottom of the market cycle, as well as strong execution on projects flowing through revenue.

Fiscal 2013 Compared to Fiscal 2012. Fiscal 2013 net sales increased $36.8 million, or 24.6 percent, over fiscal 2012. Revenue growth due to expansion of our domestic footprint accounted for the majority of the increase, or approximately 15 percentage points. The remaining 9 percentage points of the increase were due to increased volume serviced from our remaining domestic regions.

For fiscal 2013, the segment incurred an operating loss of $1.0 million, with an operating margin of negative 0.5 percent, compared to an operating loss of $2.9 million and a negative operating margin of 1.9 percent in fiscal 2012. The fiscal 2013 improvement was primarily due to the leverage on the net sales growth discussed above and positive project execution. These items were partially offset by costs incurred in fiscal 2013 to start domestic geographic expansion. In fiscal 2013, the segment was still working off projects that were bid at lower margins, but began to see higher-margin projects positively impact its results.

Architectural Framing Systems

Fiscal 2014 Compared to Fiscal 2013. Fiscal 2014 net sales increased $24.9 million, or 13.0 percent, over fiscal 2013.The addition of Alumicor accounted for approximately 8 percentage points of the increase for the year. The remainder of the increase was due to improved volumes in the U.S. storefront and finishing businesses, partially offset by volume declines caused by an anticipated gap in the schedule for the window business.

Fiscal 2014 operating income of $14.9 million was up slightly over the $14.6 million reported in fiscal 2013, while operating margins decreased to 6.9 percent in fiscal 2014 from 7.6 percent in fiscal 2013. The favorable impact of increased volumes in the U.S. storefront and finishing businesses was partially offset by lower sales in the window business related to the anticipated gap in the schedule for more complex projects, resulting in lower capacity utilization. Additionally, the Canadian storefront business that was acquired late in the year delivered an operating loss due to acquisition costs.

Fiscal 2013 Compared to Fiscal 2012. Fiscal 2013 net sales increased $16.2 million, or 9.3 percent, over fiscal 2012. Volume growth was driven by the storefront and window businesses, including share gains in target markets and domestic geographic expansion. Fiscal 2013 operating income was $14.6 million, with an operating margin of 7.6 percent, compared to $10.4 million and an operating margin of 5.9 percent in fiscal 2012. The fiscal 2013 improvement was primarily due to leverage on net sales growth in the segment, as well as better operating performance throughout the segment.

Large-Scale Optical Technologies (LSO)

Fiscal 2014 Compared to Fiscal 2013. LSO revenues in fiscal 2014 increased slightly over fiscal 2013 to $81.1 million from $79.9 million. The improvement compared to fiscal 2013 was due to a positive mix of higher value-added products. Operating income of $21.3 million was relatively flat to fiscal 2013 levels and operating margins were consistent. The impact of the strong mix of higher value-added products was largely offset by increased promotional activities and investments for growth in new geographies and markets.

Fiscal 2013 Compared to Fiscal 2012. LSO revenues were relatively flat to fiscal 2012, increasing 1.8 percent in fiscal 2013. Operating income as a percent of sales increased to 26.3 percent in fiscal 2013 from 25.0 percent in fiscal 2012, with an increase of $1.4 million in operating income. A strong mix of value-added picture framing product sales in fiscal 2013 was somewhat offset by lower volume partially due to one less week in fiscal 2013. The segment also experienced strong operating performance in fiscal 2013, which contributed to the improved margins in the year.

Consolidated Backlog

Backlog represents the dollar amount of revenues we expect to recognize in the future from firm contracts or orders received, as well as those that are in progress. Backlog is not a term defined under generally accepted accounting principles and is not a measure of contract profitability. We include a project within our backlog at the time a signed contract or a firm purchase order is received, generally as a result of a competitive bidding process. Backlog by reporting segment at March 1, 2014 and March 2, 2013 was as follows:

We expect approximately $314.5 million , or 95 percent , of our March 1, 2014 backlog to be recognized in fiscal 2015 , with the balance to be recognized in fiscal 2016 and beyond. We view backlog as an important statistic in evaluating the level of sales activity and short-term sales trends in our business. However, as backlog is only one indicator, and is not an effective indicator of our ultimate profitability, we do not believe that backlog should be used as the sole indicator of future earnings of the Company.

Acquisitions

On November 5, 2013, the Company acquired all of the shares of Alumicor Limited, a privately held business, for $52.9 million , including cash acquired of $1.6 million . Alumicor is a window, storefront, entrance and curtainwall company primarily serving the Canadian commercial construction market. Alumicor's results of operations have been included in the consolidated financial statements and within the Architectural Framing Systems segment since the date of acquisition, including $15.9 million of sales and an operating loss after incurring approximately $0.5 million of acquisition-related expenses, which are included in selling, general and administrative expenses in the Company's consolidated results of operations.

The assets and liabilities of Alumicor were recorded in the consolidated balance sheet within the Architectural Framing Systems segment as of the acquisition date, at their respective fair values. The purchase price allocation was based on the fair value of assets acquired and liabilities assumed and included total assets of $61.8 million , including goodwill and intangibles of $34.9 million , and total liabilities of $10.5 million .

In the second quarter, we acquired certain assets and liabilities of a window fabrication business as part of our strategy to grow through new products and new geographies. The acquisition is included in the results of our window business reported in the Architectural Framing Systems segment and adds to our historic window renovation product line and extends our presence in the Western United States. Results from the acquisition were immaterial to fiscal 2014 results.

Liquidity and Capital Resources

Operating activities. Cash provided by operating activities was $52.9 million in fiscal 2014, $40.5 million in fiscal 2013 and $24.6 million in fiscal 2012. Fiscal 2014 and 2013 operating cash flows were each positively impacted by the increased income reported for those fiscal years as compared to the respective prior-year periods. Additionally, fiscal 2014 benefited from improved working capital management as compared to fiscal 2013.

Non-cash working capital (current assets, excluding cash and short-term available for sale securities and short-term restricted investments, less current liabilities, excluding current portion of long-term debt) was $77.3 million at March 1, 2014 , or 10.0 percent of fiscal 2014 net sales, a metric for measuring working capital efficiency. This compares to $54.1 million at March 2, 2013 , or 7.7 percent of fiscal 2013 net sales, and $44.4 million at March 3, 2012 , or 6.7 percent of fiscal 2012 net sales. The change in fiscal 2014 comes from including partial year results of Alumicor, growth in the base business and extending our geographic footprint in certain businesses. We believe that we have continued to manage working capital effectively while growing the business.

Investing Activities. Investing activities used cash of $44.0 million in fiscal 2014 and $57.1 million in fiscal 2013, while cash provided was $18.5 million in fiscal 2012. In fiscal 2014, we made capital investments of $41.9 million as we made investments for growth, productivity and product development capabilities, including a new state-of-the-art coater in our Architectural Glass segment. We reduced our restricted investments by $23.9 million, as we released $10.0 million of cash held in escrow for the recovery zone facility bonds that was used to redeem the bonds and also released $12.0 million of cash collateral to unrestricted cash related to the letter of credit supporting these bonds. We decreased our investments in marketable securities by $26.5 million in fiscal 2014 to fund the acquisition of Alumicor.

In the current year, we completed two acquisitions as part of our strategy to grow through new products and new geographies. In the second quarter, we acquired certain assets and liabilities of a window fabrication business, which is included in the results of our window business within the Architectural Framing Systems segment. During the third quarter, we acquired the outstanding shares of Alumicor Limited; the results of operations have been included in the consolidated financial statements and within the Architectural Framing Systems segment since the date of acquisition.

In fiscal 2013, we made capital investments of $34.7 million for growth and productivity improvements, as well as equipment to support new product introductions, and maintenance capital. The net position of our investments for fiscal 2013 resulted in $17.6 million in net purchases as a result of generating excess cash through operating activities noted above. Net purchases of $4.5 million for restricted investments during fiscal 2013 were the result of $10.0 million of industrial development bonds (reflected in financing activities) that were made available for current and future investment in our storefront and entrance business in Michigan.

Fiscal 2012 investing activities included $10.3 million in proceeds from the sale and leaseback of equipment. Net proceeds of $12.7 million from restricted investments during fiscal 2012 resulted from releasing money market funds that were required to cover exposures under letters of credit that were previously held outside of our credit facility. The net position of our investments

for fiscal 2012 resulted in $6.6 million in net sale proceeds, as we sold investments to fund operating activities. New capital investments in fiscal 2012 totaled $9.7 million, primarily for safety and maintenance projects.

We expect fiscal 2015 capital expenditures to be approximately $40 million for investments for growth, productivity and product development capabilities, as well as maintenance capital.

We continue to review our portfolio of businesses and their assets in comparison to our internal strategic and performance objectives. As part of this review, we may acquire other businesses, pursue geographic expansion, take actions to manage capacity, and/or further invest in, fully divest and/or sell parts of our current businesses. In the first quarter of fiscal 2014, we completed the temporary shutdown of our Architectural Glass segment business in Utah to align overall capacity with the demand we are expecting over the next two years.

At March 1, 2014 , we had one sale and leaseback agreement for equipment that provides an option to purchase the equipment at projected future fair market value upon expiration of the lease in 2018. The lease is classified as an operating lease. We had a deferred gain of $3.6 million under the sale and leaseback transaction, which is included in the balance sheet as other current and non-current liabilities. The average annual lease payment over the life of the remaining lease is $1.6 million .

Financing Activities. Total outstanding borrowings at March 1, 2014 were $20.7 million, compared to $30.8 million as of March 2, 2013 and $21.0 million at March 3, 2012 . During the first quarter of fiscal 2014, $10.0 million of recovery zone facility bonds that had previously been issued for future investment in the Company's Architectural Glass fabrication facility in Utah were redeemed at par. Our debt consists of $20.4 million of industrial revenue bonds and $0.3 million of other debt. The industrial revenue bonds mature in fiscal years 2021 through 2043 and the other debt matures in fiscal years 2015 through 2021. There were small amounts of current debt at March 1, 2014 and March 3, 2012. At March 2, 2013, $10.0 million of the recovery zone facility bonds were classified as current as we repaid these bonds related to our Utah facility in early fiscal 2014. Our debt-to-total-capital ratio was 5.5 percent at March 1, 2014 and 8.5 percent at March 2, 2013 .

During the third quarter of fiscal 2014, the Company entered into an amendment to its existing $100.0 million revolving credit facility. The expiration date was extended by one year to November 2018 and the letter of credit facility was reduced by $10.0 million to $50.0 million , the outstanding amounts of which decrease the available commitment. No other provisions of the original agreement were materially amended by the amended credit agreement. No borrowings were outstanding under the facility as of March 1, 2014 or March 2, 2013 . Letters of credit issued under the facility decrease the amount of available commitment; $76.5 million was available under the facility at March 1, 2014 and $76.6 million was available at March 2, 2013 .

The credit facility requires that we maintain a minimum level of net worth as defined in the credit facility based on certain quarterly financial calculations. The minimum required net worth computed in accordance with the credit agreement at March 1, 2014 was $287.5 million , whereas our net worth as defined in the credit facility was $352.6 million . The credit facility also requires that we maintain an adjusted debt-to-EBITDA ratio of not more than 3.00 . This ratio is computed quarterly, with EBITDA computed on a rolling four-quarter basis. For purposes of calculating the adjusted debt in the adjusted debt-to-EBITDA ratio, we reduce non-credit facility debt for up to $25 million to the extent of unrestricted cash balances, cash equivalents and short-term marketable securities available for sale in excess of $15 million . Our ratio was 0.25 at March 1, 2014 . If we are not in compliance with either of these covenants, the lenders may terminate the commitment and/or declare any loan then outstanding to be immediately due and payable. At March 1, 2014 , we were in compliance with the financial covenants of the credit facility.

During fiscal 2004, the Board of Directors authorized a share repurchase program of 1,500,000 shares of common stock. The Board of Directors increased this authorization by 750,000 shares in January 2008 and by 1,000,000 in October 2008. There were no share repurchases during either fiscal 2014 or 2013. We have purchased a total of 2,279,123 shares, at a total cost of $29.7 million, since the inception of this program. We have remaining authority to repurchase 970,877 shares under this program, which has no expiration date.

In addition to the shares repurchased under the repurchase plan, during fiscal 2014 and 2013 we also acquired $3.6 million and $1.5 million , respectively, of Company stock from employees in order to satisfy stock-for-stock option exercises or withholding tax obligations related to stock-based compensation, pursuant to terms of Board and shareholder-approved compensation plans.

Other Financing Activities. The following summarizes our significant contractual obligations that impact our liquidity as of March 1, 2014 :

From time to time, we acquire the use of certain assets, such as warehouses, automobiles, forklifts, vehicles, office equipment, hardware, software and some manufacturing equipment through operating leases. Many of these operating leases have termination penalties. However, because the assets are used in the conduct of our business operations, it is unlikely that any significant portion of these operating leases would be terminated prior to the normal expiration of their lease terms. Therefore, we consider the risk related to termination penalties to be minimal.

We have purchase obligations for raw material commitments and capital expenditures. As of March 1, 2014 , these obligations totaled $96.2 million.

We have a foreign exchange forward contract with a U.S. dollar notional value of $3.0 million with the objective of reducing the exposure to fluctuations in the Euro related to a planned capital equipment purchase. The fair value of this contract was immaterial at March 1, 2014 . We report the effective portion of the gain or loss on a cash flow hedge as a component of other comprehensive income, and any gain or loss is included in the value of the capital asset and will be recognized in earnings over the life of the asset.

We expect to make contributions of $0.8 million to our defined-benefit pension plans in fiscal 2015, which will equal or exceed our minimum funding requirements.

As of March 1, 2014 , we had $5.2 million and $1.5 million of unrecognized tax benefits and environmental liabilities, respectively. We expect approximately $0.4 million of the unrecognized tax benefits to lapse during the next 12 months. We are unable to reasonably estimate in which future periods the remaining unrecognized tax benefits and environmental liabilities will ultimately be settled.

At March 1, 2014 , we had ongoing letters of credit related to construction contracts and certain industrial revenue bonds. The Company's $20.4 million of industrial revenue bonds are supported by $21.0 million of letters of credit that reduce availability of funds under our $100.0 million credit facility. The letters of credit by expiration period were as follows at March 1, 2014 :

In addition to the above standby letters of credit, which were predominantly issued for our industrial revenue bonds, we are required, in the ordinary course of business, to provide surety or performance bonds that commit payments to our customers for any non-performance by us. At March 1, 2014 , $98.4 million of our backlog was bonded by performance bonds with a face value of $275.7 million . Performance bonds do not have stated expiration dates, as we are released from the bonds upon completion of the contract. We have never been required to make any payments related to these performance bonds with respect to any of our current portfolio of businesses.

We believe that current cash on hand and available capacity under our committed revolving credit facility, as well as the expected cash to be generated from future operating activities, will be adequate to fund our working capital requirements, planned capital expenditures and dividend payments over the next 12 months. We have total cash and short-term available for sale securities of

$28.7 million , and $76.5 million available under our credit facility at March 1, 2014 . We believe that this will provide us with the financial strength to continue our growth strategy as our end markets continue to improve.

Off-balance sheet arrangements. With the exception of operating leases, we had no off-balance sheet financing arrangements at March 1, 2014 or March 2, 2013 .

Outlook

The following statements are based on our current expectations for fiscal 2015 results. These statements are forward-looking, and actual results may differ materially.

Recently Issued Accounting Pronouncements

See New Accounting Standards set forth in Note 1 of the Notes to Consolidated Financial Statements under Item 8 of this Form 10-K for information pertaining to recently adopted accounting standards or accounting standards to be adopted in the future, which is incorporated by reference herein.

Critical Accounting Policies

Management has evaluated the accounting policies and estimates used in the preparation of the accompanying financial statements and related notes, and believes those policies and estimates to be reasonable and appropriate. We believe that the most critical accounting policies and estimates applied in the presentation of our financial statements relate to accounting for future events. Future events and their effects cannot be determined with absolute certainty. Therefore, management is required to exercise judgment both in assessing the likelihood that a liability has been incurred as well as in estimating the amount of potential loss. We have identified the following accounting policies as critical to our business and in the understanding of our results of operations and financial position:

Revenue recognition - Our standard product sales terms are "free on board" (FOB) shipping point or FOB destination, and revenue is recognized when title has transferred. However, our Architectural Services segment business enters into fixed-price contracts for full-service commercial building glass installation and renovation services, which are accounted for as construction-type contracts. These contracts are typically performed over a 12- to 18-month timeframe, and we record revenue for these contracts on a percentage-of-completion basis as we are able to reasonably estimate total contract revenue and total contract costs. The contracts entered into clearly specify the enforceable rights of the parties, the consideration and the terms of settlement, and both parties can be expected to satisfy all obligations under the contract. During fiscal 2014 , approximately 26 percent of our consolidated sales were recorded on a percentage-of-completion basis. Under this methodology, we compare the total costs incurred to date to the total estimated costs for the contract, and record that proportion of the total contract revenue in the period. Contract costs include materials, labor and other direct costs related to contract performance. Given our ability to make reasonable estimates of our total contract revenues and total contract costs, we believe utilizing the cost-to-cost method for revenue recognition provides the greatest degree of precision in measuring progress toward completion of the installation contracts. Provisions are established for estimated losses, if any, on uncompleted contracts in the period in which such losses are determined. Amounts representing contract change orders, claims or other items are included in contract revenue only when customers have approved them. A significant number of estimates are used in these computations.

Goodwill impairment - To determine if there has been any impairment in accordance with accounting standards, we evaluate the goodwill on our balance sheet annually or more frequently if impairment indicators exist through a two-step process. In step one, we value each of our reporting units and compare these values to the reporting units' net book value, including goodwill. If the fair value is less than the net book value, we perform step two, which determines the amount of goodwill to impair. Each of our seven business units represents a reporting unit under applicable accounting standards. We were not required to perform step two for fiscal 2014 ; the estimated fair value of each of the reporting units significantly exceeded their book value utilizing the discounted cash flow methodology at March 1, 2014 .

Although we consider public information for transactions made on businesses similar to ours, since there were no market comparables identified, we base our determination of fair value using a discounted cash flow methodology that involves significant judgments based upon projections of future performance. In developing our discounted cash flow analysis, assumptions about future revenues and expenses, capital expenditures and changes in working capital are based on our annual operating plan and long-term business plan for each of our reporting units. These plans take into consideration numerous factors including historical experience, anticipated future economic conditions and growth expectations for the industries and end markets in which we

participate. These assumptions are determined over a five-year, long-term planning period. The five-year growth rates for revenues and operating profits vary for each reporting unit being evaluated. Revenues and operating profit beyond the five-year period are projected to grow at a nominal perpetual growth rate for all reporting units. The discount rate calculations are determined by assuming a company beta, market premium risk, size premium, the cost of debt and debt-to-capital ratio of a market participant.

A significant change in the factors noted above could cause us to reduce the estimated fair value of some or all of our reporting units and recognize a corresponding impairment of our goodwill in connection with a future goodwill impairment test. There can be no assurances that these forecasts will be attained. Adverse changes in strategy, market conditions or assumed market capitalization may result in an impairment of goodwill.

Reserves for disputes and claims regarding product liability and warranties - From time to time, we are subject to claims associated with our products and services, principally as a result of disputes with our customers involving the performance or aesthetics of our architectural products and services. The time period from when a claim is asserted to when it is resolved, either by dismissal, negotiation, settlement or litigation, can be several years. While we maintain product liability insurance, the insurance policies include significant self-retention of risk in the form of policy deductibles. In addition, certain claims could be determined to be uninsured. We reserve based on our estimates of known claims, as well as on anticipated claims for possible product warranty and rework costs based on historical product liability claims as a ratio of sales.

Self-insurance reserves - We obtain substantial amounts of commercial insurance for potential losses for general liability, workers' compensation, automobile liability, employment practices, architect's and engineer's errors and omissions risk, product re-work and other miscellaneous coverages. However, an amount of risk is retained on a self-insured basis through a wholly-owned insurance subsidiary; as a result, a material construction project rework event could have a material adverse effect on our operating results. Reserve requirements are established based on actuarial projections of ultimate losses.

Income taxes - We record a tax provision for the anticipated tax consequences of the reported results of operations. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those deferred tax assets and liabilities are expected to be realized or settled. In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with management's expectations could have a material impact on the Company's financial condition and operating results.

As part of our ongoing financial reporting process, a collaborative effort is undertaken involving our management with responsibility for financial reporting, product and project management, quality, legal and tax, and outside advisors such as consultants, engineers, lawyers and actuaries. The results of this effort provide management with the necessary information on which to base its judgments on these future events and develop the estimates used to prepare the financial statements. We believe that the amounts recorded in the accompanying financial statements related to these events are based on the best estimates and judgments of Apogee management. However, outcomes could differ from our estimates and could materially adversely affect our future operating results, financial position and cash flows.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our investment portfolio consists of municipal bonds. At March 1, 2014 , we had total investments of $11.5 million , which are considered available-for-sale securities. Although these investments are subject to the credit risk of the issuer and/or letter of credit issuer, we manage our investment portfolio to limit our exposure to any one issuer.

We do not use derivative financial instruments to manage interest rate risk or to speculate on future changes in interest rates. Accordingly, a rise in interest rates could negatively affect the fair value of our municipal bond portfolio. To manage our direct risk from changes in market interest rates, management actively monitors the interest-sensitive components of our balance sheet, primarily debt obligations and fixed income securities, as well as market interest rates, to minimize the impact of changes in interest rates on net earnings and cash flow.

The primary measure of interest rate risk is the simulation of net income under different interest rate environments. The approach used to quantify interest rate risk is a sensitivity analysis. This approach calculates the impact on net earnings, relative to a base case scenario, of rates increasing or decreasing gradually over the next 12 months by 200 basis points. This change in interest rates affecting our financial instruments at March 1, 2014 would result in an approximatel y $0.1 million impac t to net earnings. The Company's investments exceeded its debt at March 1, 2014 , so as interest rates increase, net earnings increase; as interest rates decrease, net earnings decrease.

In addition to the market risk related to interest rate changes, the commercial construction markets in which our businesses operate are highly affected by changes in interest rates and, therefore, significant interest rate fluctuations could materially impact our operating results.

Due to our Canadian storefront and Brazilian glass businesses, we conduct business in locations outside of the United States, and are subject to market risk due to changes in the value of foreign currencies in relation to our reporting currency, the U.S. dollar. We generally do not use derivative financial instruments to manage these risks. The functional currencies of our foreign operations is the local currency in the country of domicile. We manage these operating activities at the local level and revenues, costs, assets and liabilities are generally denominated in local currencies, thereby mitigating the risk associated with changes in foreign exchange. However, our results of operations and assets and liabilities are reported in U.S. dollars, and thus will fluctuate with changes in exchange rates between Canadian dollar, Brazilian real and the U.S. dollar.

From time to time, we may enter into short duration foreign currency contracts to hedge foreign currency risks. As these foreign currency contracts generally have an original maturity date of less than one year, there is no material foreign currency risk. We report the effective portion of the gain or loss on a cash flow hedge as a component of other comprehensive income, and any gain or loss is reclassified into earnings in the period in which the hedged transaction affects net earnings.

Our domestic businesses generally sell within the United States, with sales made outside of the United States generally denominated in U.S. dollars.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Management's Report on Internal Control over Financial Reporting

Management of Apogee Enterprises, Inc. and its subsidiaries (the Company) is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) of the Securities Exchange Act of 1934. The Company's 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. The Company's internal control over financial reporting includes those policies and procedures that (1) pertain to maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of the financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the financial statements.

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

The Company's management assessed the effectiveness of the Company's internal control over financial reporting as of March 1, 2014 , using criteria set forth in Internal Control-Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, the Company's management believes that, as of March 1, 2014 , the Company's internal control over financial reporting was effective based on those criteria.

Management has excluded from its assessment the internal control over financial reporting at Alumicor, which was acquired on November 5, 2013, and whose financial statements constitute 10 percent of total assets, two percent of revenues and a negative one percent of operating income on the consolidated financial statement amounts as of and for the year ended March 1, 2014.

The Company's independent registered public accounting firm, Deloitte & Touche LLP, has issued a report on the effectivene ss of the Company's internal control over financial reporting as of March 1, 2014 . That report is set forth immediately following the report of Deloitte & Touche LLP on the consolidated financial statements included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Apogee Enterprises, Inc.

Minneapolis, MN

We have audited the accompanying consolidated balance sheets of Apogee Enterprises, Inc. and subsidiaries (the "Company") as of March 1, 2014 and March 2, 2013, and the related consolidated results of operations, statements of comprehensive earnings, statements of cash flow, and statements of shareholders' equity for each of the three years in the period ended March 1, 2014. Our audits also included the financial statement schedule listed in the Table of Contents at Item 15. These consolidated financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on the consolidated financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Apogee Enterprises, Inc. and subsidiaries at March 1, 2014 and March 2, 2013, and the results of their operations and their cash flows for each of the three years in the period ended March 1, 2014, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's internal control over financial reporting as of March 1, 2014, based on the criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated April 30, 2014, expressed an unqualified opinion on the Company's internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Apogee Enterprises, Inc.

Minneapolis, MN

We have audited the internal control over financial reporting of Apogee Enterprises, Inc. and subsidiaries (the "Company") as of March 1, 2014, based on criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. As described in Management's Report on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at Alumicor Limited (Alumicor), which was acquired on November 5, 2013 and whose financial statements constitute 10% of total assets, 2% of revenues, and (1%) of net income of the consolidated financial statement amounts as of and for the year ended March 1, 2014. Accordingly, our audit did not include the internal control over financial reporting at Alumicor. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel 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. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 1, 2014, based on the criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule listed in the Table of Contents at Item 15 as of and for the year ended March 1, 2014, of the Company and our report dated April 30, 2014 expressed an unqualified opinion on those consolidated financial statements and financial statement schedule.
