DOCUMENTS INCORPORATED BY REFERENCE    

HEICO Corporation through its subsidiaries (collectively, "HEICO," "we," "us," "our" or the "Company") believes it is the world's largest manufacturer of Federal Aviation Administration ("FAA")-approved jet engine and aircraft component replacement parts, other than the original equipment manufacturers ("OEMs") and their subcontractors.  HEICO also believes it is a leading manufacturer of various types of electronic equipment for the aviation, defense, space, medical, telecommunications and electronics industries.

The Company was originally organized in 1957 as a holding company known as HEICO Corporation.  As part of a reorganization completed in 1993, the original holding company (formerly known as HEICO Corporation) was renamed as HEICO Aerospace Corporation and a new holding corporation known as HEICO Corporation was created.  The reorganization did not result in any change in the business of the Company, its consolidated assets or liabilities or the relative interests of its shareholders.

Our business is comprised of two operating segments:

The Flight Support Group . Our Flight Support Group ("FSG"), consisting of HEICO Aerospace Holdings Corp. and HEICO Flight Support Corp. and their collective subsidiaries, accounted for 63%, 64% and 68% of our net sales in fiscal 2017, 2016 and 2015, respectively.  The Flight Support Group uses proprietary technology to design and manufacture jet engine and aircraft component replacement parts for sale at lower prices than those manufactured by OEMs.  These parts are approved by the FAA and are the functional equivalent of parts sold by OEMs.  In addition, the Flight Support Group repairs, overhauls and distributes jet engine and aircraft components, avionics and instruments for domestic and foreign commercial air carriers and aircraft repair companies as well as military and business aircraft operators; and manufactures thermal insulation products, complex composite assemblies and other component parts primarily for aerospace, defense, industrial and commercial applications.

The Electronic Technologies Group . Our Electronic Technologies Group ("ETG"), consisting of HEICO Electronic Technologies Corp. and its subsidiaries, accounted for 37%, 36% and 32% of our net sales in fiscal 2017, 2016 and 2015, respectively.  Through our Electronic Technologies Group, which derived approximately 64%, 65% and 56% of its net sales in fiscal 2017, 2016 and 2015, respectively, from the sale of products and services to United States ("U.S.") and foreign military agencies, prime defense contractors and both commercial and defense satellite and spacecraft manufacturers, we design, manufacture and sell various types of electronic, microwave and electro-optical products, including infrared simulation and test equipment, laser rangefinder receivers, electrical power supplies, back-up power supplies, power conversion products, underwater locator beacons, electromagnetic interference and radio frequency interference shielding, high power capacitor charging power supplies, amplifiers,

traveling wave tube amplifiers, photodetectors, amplifier modules, microwave power modules, flash lamp drivers, laser diode drivers, arc lamp power supplies, custom power supply designs, cable assemblies, high voltage power supplies, high voltage interconnection devices and wire, high voltage energy generators, high frequency power delivery systems, three-dimensional microelectronic and stacked memory products, harsh environment electronic connectors and other interconnect products, radio frequency ("RF") and microwave amplifiers, transmitters and receivers, wireless cabin control systems, solid state power distribution and management systems, crashworthy and ballistically self-sealing auxiliary fuel systems, communications and electronic intercept receivers and tuners, fuel level sensing systems, high-speed interface products that link devices such as telemetry receivers, digital cameras, high resolution scanners, simulation systems and test systems to almost any computer and high performance active antenna systems for commercial aircraft, precision guided munitions, other defense applications and commercial uses.

HEICO has continuously operated in the aerospace industry for over 60 years. Since assuming control in 1990, our current management has achieved significant sales and profit growth through a broadened line of product offerings, an expanded customer base, increased research and development expenditures and the completion of a number of acquisitions.  As a result of internal growth and acquisitions, our net sales from continuing operations have grown from $26.2 million in fiscal 1990 to $1,524.8 million in fiscal 2017, representing a compound annual growth rate of approximately 16%.  During the same period, we improved our net income from $2.0 million to $186.0 million, representing a compound annual growth rate of approximately 18%.

Acquisitions have been an important element of our growth strategy over the past twenty-seven years, supplementing our organic growth.  Since 1990, we have completed approximately 66 acquisitions complementing the niche segments of the aviation, defense, space, medical, telecommunications and electronics industries in which we operate.  We typically target acquisition opportunities that allow us to broaden our product offerings, services and technologies while expanding our customer base and geographic presence.  Even though we have historically pursued an active acquisition policy, our disciplined acquisition strategy involves limiting acquisition candidates to businesses that we believe will continue to grow, offer strong cash flow and earnings potential, and are available at fair prices. See Note 2, Acquisitions, of the Notes to Consolidated Financial Statements for further information regarding our recent acquisitions.

The Flight Support Group, headquartered in Hollywood, Florida, serves a broad spectrum of the aviation industry, including (i) commercial airlines and air cargo carriers; (ii) repair and overhaul facilities; (iii) OEMs; and (iv) U.S. and foreign governments.

The Flight Support Group competes with the leading industry OEMs and, to a lesser extent, with a number of smaller, independent parts distributors.  Historically, the three principal jet engine OEMs, General Electric (including CFM International), Pratt & Whitney and Rolls Royce, have been the sole source of substantially all jet engine replacement parts for their jet engines.  Other OEMs have been the sole source of replacement parts for their aircraft component parts.  While we believe that we currently supply approximately 2% of the market for jet engine and aircraft component replacement parts, we have in recent years been adding new products to our line at a rate of approximately 300 to 500 Parts Manufacturer Approvals ("PMA" or "PMAs") per year.  We have developed for our customers approximately 10,000 parts for which PMAs have been received from the FAA.

Jet engine and aircraft component replacement parts can be categorized by their ongoing ability to be repaired and returned to service.  The general categories in which we participate are as follows: (i) rotable; (ii) repairable; and (iii) expendable.  A rotable is a part which is removed periodically as dictated by an operator's maintenance procedures or on an as needed basis and is typically repaired or overhauled and re-used an indefinite number of times.  An important subset of rotables is "life limited" parts.  A life limited rotable has a designated number of allowable flight hours and/or cycles (one take-off and landing generally constitutes one cycle) after which it is rendered unusable.  A repairable is similar to a rotable except that it can only be repaired a limited number of times before it must be discarded.  An expendable is generally a part which is used and not thereafter repaired for further use.

Jet engine and aircraft component replacement parts are classified within the industry as (i) factory-new; (ii) new surplus; (iii) overhauled; (iv) repairable; and (v) as removed.  A factory-new or new surplus part is one that has never been installed or used.  Factory-new parts are purchased from FAA-approved manufacturers (such as HEICO or OEMs) or their authorized distributors.  New surplus parts are purchased from excess stock of airlines, repair facilities or other redistributors.  An overhauled part is one that has been completely repaired and inspected by a licensed repair facility such as ours.  An aircraft spare part is classified as "repairable" if it can be repaired by a licensed repair facility under applicable regulations.  A part may also be classified as "repairable" if it can be removed by the operator from an aircraft or jet engine while operating under an approved maintenance program and is airworthy and meets any manufacturer or time and cycle restrictions applicable to the part.  A "factory-new," "new surplus" or "overhauled" part designation indicates that the part can be immediately utilized on an aircraft.  A part in "as removed" or "repairable" condition requires inspection and possibly functional testing, repair or overhaul by a licensed facility prior to being returned to service in an aircraft.

Factory-New Jet Engine and Aircraft Component Replacement Parts .  The Flight Support Group engages in the research and development, design, manufacture and sale of FAA-approved replacement parts that are sold to domestic and foreign commercial air carriers and aircraft repair and overhaul companies.  Our principal competitors are aircraft engine and aircraft component manufacturers.  The Flight Support Group's factory-new replacement parts include various jet engine and aircraft component replacement parts.  A key element of our growth strategy is the continued design and development of an increasing number of PMA replacement parts in order

to further penetrate our existing customer base and obtain new customers.  We select the jet engine and aircraft component replacement parts to design and manufacture through a selection process which analyzes industry information to determine which replacement parts are suitable candidates.

Repair and Overhaul Services .  The Flight Support Group provides repair and overhaul services on selected jet engine and aircraft component parts, as well as on avionics, instruments, composites and flight surfaces of commercial aircraft operated by domestic and foreign commercial airlines.  The Flight Support Group also provides repair and overhaul services including avionics and navigation systems as well as subcomponents and other instruments utilized on military aircraft operated by the U.S. government and foreign military agencies and for aircraft repair and overhaul companies.  Our repair and overhaul operations require a high level of expertise, advanced technology and sophisticated equipment.  Services include the repair, refurbishment and overhaul of numerous accessories and parts mounted on gas turbine engines and airframes.  Components overhauled include fuel pumps, generators, fuel controls, pneumatic valves, starters and actuators, turbo compressors and constant speed drives, hydraulic pumps, valves and actuators, wheels and brakes, composite flight controls, electro-mechanical equipment, auxiliary power unit accessories and thrust reverse actuation systems.  Some of the repair and overhaul services provided by the Flight Support Group are proprietary repairs approved by an FAA-qualified designated engineering representative ("DER").  Such FAA-approved repairs (DER-approved repairs) typically create cost savings or provide engineering flexibility.  The Flight Support Group also provides commercial airlines, regional operators, asset management companies and Maintenance, Repair and Overhaul ("MRO") providers with high quality and cost effective niche accessory component exchange services as an alternative to OEMs' spares services.

Distribution .  The Flight Support Group distributes FAA-approved parts including hydraulic, pneumatic, structural, interconnect, mechanical and electro-mechanical components for the commercial, regional and general aviation markets.  The Flight Support Group also is a leading supplier, distributor, and integrator of military aircraft parts and support services primarily to foreign military organizations allied with the U.S. Further, we believe the Flight Support Group is a leading provider of products and services necessary to maintain up-to-date F-16 fighter aircraft operational capabilities. 

Manufacture of Specialty Aircraft/Defense Related Parts and Subcontracting for OEMs .  The Flight Support Group engineers, designs and manufactures thermal insulation blankets and parts as well as renewable/reusable insulation systems primarily for aerospace, defense, commercial and industrial applications.  The Flight Support Group also manufactures specialty components for sale as a subcontractor for aerospace and industrial original equipment manufacturers and the U.S. government. Additionally, the Flight Support Group manufactures advanced niche components and complex composite assemblies for commercial aviation, defense and space applications and manufactures expanded foil mesh, which is integrated into composite aerospace structures for lightning strike protection in fixed and rotary wing aircraft.

FAA Approvals and Product Design .  Non-OEM manufacturers of jet engine and aircraft component replacement parts must receive a PMA from the FAA to sell the replacement part.  The PMA approval process includes the submission of sample parts, drawings and testing data to one of the FAA's Aircraft Certification Offices where the submitted data are analyzed.  We believe that an applicant's ability to successfully complete the PMA process is limited by several factors, including (i) the agency's confidence level in the applicant; (ii) the complexity of the part; (iii) the volume of PMAs being filed; and (iv) the resources available to the FAA.  We also believe that companies such as HEICO that have demonstrated their advanced design engineering and manufacturing capabilities, including an established favorable track record with the FAA, generally receive a faster turnaround time in the processing of PMA applications.  Finally, we believe that the PMA process creates a significant barrier to entry in this market niche through both its technical demands and its limits on the rate at which competitors can bring products to market.

As part of our growth strategy, we have continued to increase our research and development activities.  Research and development expenditures by the Flight Support Group, which were approximately $.3 million in fiscal 1991, increased to approximately $17.9 million in fiscal 2017, $17.4 million in fiscal 2016 and $17.7 million in fiscal 2015.  We believe that our Flight Support Group's research and development capabilities are a significant component of our historical success and an integral part of our growth strategy.  In recent years, the FAA granted us PMAs for approximately 300 to 500 new parts and approximately 300 to 400 new DER-approved repairs per year; however, no assurance can be given that the FAA will continue to grant PMAs or DER-approved repairs or that we will achieve acceptable levels of net sales and gross profits on such parts or repairs in the future.

We benefit from our proprietary rights relating to certain design, engineering and manufacturing processes and repair and overhaul procedures.  Customers often rely on us to provide initial and additional components, as well as to redesign, re-engineer, replace or repair and provide overhaul services on such aircraft components at every stage of their useful lives.  In addition, for some products, our unique manufacturing capabilities are required by the customer's specifications or designs, thereby necessitating reliance on us for production of such designed products.

We have no material patents for the proprietary techniques, including software and manufacturing expertise, we have developed to manufacture jet engine and aircraft component replacement parts and instead, we primarily rely on trade secret protection.  Although our proprietary techniques and software and manufacturing expertise are subject to misappropriation or obsolescence, we believe that we take appropriate measures to prevent misappropriation or obsolescence from occurring by developing new techniques and improving existing methods and processes, which we will continue on an ongoing basis as dictated by the technological needs of our business.

We believe that, based on our competitive pricing, reputation for high quality, short lead time requirements, strong relationships with domestic and foreign commercial air carriers and repair stations (companies that overhaul aircraft engines and/or components), and successful

track record of receiving PMAs and DER-approved repairs from the FAA, we are uniquely positioned to continue to increase the products and services offered and gain market share.

Our Electronic Technologies Group's strategy is to design and produce mission-critical subcomponents for smaller, niche markets, but which are utilized in larger systems – systems like power, targeting, tracking, identification, simulation, testing, communications, lighting, surgical, medical imaging, baggage scanning, telecom and computer systems.  These systems are, in turn, often located on another platform, such as aircraft, rotorcraft, satellites, ships, spacecraft, land vehicles, handheld devices and other platforms.

Electro-Optical Infrared Simulation and Test Equipment .  The Electronic Technologies Group believes it is a leading international designer and manufacturer of niche state-of-the-art simulation, testing and calibration equipment used in the development of missile seeking technology, airborne targeting and reconnaissance systems, shipboard targeting and reconnaissance systems, space-based sensors as well as ground vehicle-based systems. These products include infrared scene projector equipment, such as our MIRAGE IR Scene Simulator, high precision blackbody sources, software and integrated calibration systems.

Simulation equipment allows the U.S. government and allied foreign military to save money on missile testing as it allows infrared-based missiles to be tested on a multi-axis, rotating table instead of requiring the launch of a complete missile.  In addition, several large military prime contractors have elected to purchase such equipment from us instead of maintaining internal staff to do so because we can offer a more cost-effective solution.  Our customers include major U.S. Department of Defense weapons laboratories and defense prime contractors.

Electro-Optical Laser Products .  The Electronic Technologies Group believes it is a leading designer and maker of Laser Rangefinder Receivers and other photodetectors used in airborne, vehicular and handheld targeting systems manufactured by major prime military contractors.  Most of our Rangefinder Receiver product offering consists of complex and patented products which detect reflected light from laser targeting systems and allow the systems to confirm target accuracy and calculate target distances prior to discharging a weapon system.  Some of these products are also used in laser eye surgery systems for tracking ocular movement.

Electro-Optical, Microwave and Other Power Equipment .  The Electronic Technologies Group produces power supplies, amplifiers and flash lamp drivers used in laser systems for military, medical and other applications that are sometimes utilized with our rangefinder receivers.  We also produce emergency back-up power supplies and batteries used on commercial aircraft and business jets for services such as emergency exit lighting, emergency fuel shut-off, power door assists, cockpit voice recorders and flight computers. We also design and manufacture next generation wireless cabin control systems, solid state power distribution and management systems and fuel level sensing systems for business jets and for general aviation, as well as for the military/defense market. We offer custom or standard designs that solve

challenging OEM requirements and meet stringent safety and emissions requirements.  Our power electronics products include capacitor charger power supplies, laser diode drivers, arc lamp power supplies and custom power supply designs.

Our microwave products are used in both commercial and military satellites, spacecraft and in electronic warfare systems.  These products, which include isolators, bias tees, circulators, latching ferrite switches and waveguide adapters are used in satellites and spacecraft to control or direct energy according to operator needs. As satellites are frequently used as sensors for stand-off warfare, we believe this product line further supports our goal of increasing our activity in the stand-off market. Additionally, our microwave products include converters, receivers, transmitters, amplifiers, frequency sources and related sub-systems that address the majority of major satellite frequencies. We believe we are a leading supplier of the niche products which we design and manufacture for this market, a market that includes commercial satellites.  Our customers for these products include satellite and spacecraft manufacturers.

Electromagnetic and Radio Interference Shielding .  The Electronic Technologies Group designs and manufactures shielding used to prevent electromagnetic energy and radio frequencies from interfering with other devices, such as computers, telecommunication devices, avionics, weapons systems and other electronic equipment.  Our products include a patented line of shielding applied directly to circuit boards and a line of gasket-type shielding applied to computers and other electronic equipment.  Our customers consist essentially of medical, electronics, telecommunications and defense equipment producers.

High-Speed Interface Products .  The Electronic Technologies Group designs and manufactures advanced high-technology, high-speed interface products utilized in homeland security, defense, medical research, astronomical and other applications across numerous industries.

As part of our growth strategy, we have continued to invest in our research and development activities.  Research and development expenditures by the Electronic Technologies Group were $28.6 million in fiscal 2017, $27.3 million in fiscal 2016 and $21.0 million in fiscal 2015.  We believe that our Electronic Technologies Group's research and development capabilities are a significant component of our historical success and an integral part of our growth strategy.

See Note 14, Operating Segments, of the Notes to Consolidated Financial Statements for financial information by operating segment and by geographic areas.

Each of our operating segments independently conducts distribution, sales and marketing efforts directed at their respective customers and industries and, in some cases, collaborates with other operating divisions and subsidiaries within its group for cross-marketing efforts.  Sales and marketing efforts are conducted primarily by in-house personnel and, to a lesser extent, by independent manufacturers' representatives.  Generally, the in-house sales personnel receive a base salary plus commission and manufacturers' representatives receive a commission on sales.

We believe that direct relationships are crucial to establishing and maintaining a strong customer base and, accordingly, our senior management is actively involved in our marketing activities, particularly with established customers.  We are also a member of various trade and business organizations related to the commercial aviation industry, such as the Aerospace Industries Association, which we refer to as AIA, the leading trade association representing the nation's manufacturers of commercial, military and business aircraft, aircraft engines and related components and equipment.  Due in large part to our established industry presence, we enjoy strong customer relations, name recognition and repeat business.

We sell our products to a broad customer base consisting of domestic and foreign commercial and cargo airlines, repair and overhaul facilities, other aftermarket suppliers of aircraft engine and airframe materials, OEMs, domestic and foreign military units, electronic manufacturing services companies, manufacturers for the defense industry as well as medical, telecommunications, scientific, and industrial companies.  No one customer accounted for sales of 10% or more of total consolidated sales from continuing operations during any of the last three fiscal years.  Net sales to our five largest customers accounted for approximately 18%, 21% and 17% of total net sales in fiscal 2017, 2016 and 2015, respectively.

The aerospace product and service industry is characterized by intense competition. Some of our competitors have substantially greater name recognition, inventories, complementary product and service offerings, financial, marketing and other resources than we do.  As a result, such competitors may be able to respond more quickly to customer requirements

than we can.  Moreover, smaller competitors may be in a position to offer more attractive pricing as a result of lower labor costs and other factors.

Our jet engine and aircraft component replacement parts business competes primarily with aircraft engine and aircraft component manufacturers.  The competition is principally based on price and service to the extent that our parts are interchangeable.  With respect to other aerospace products and services sold by the Flight Support Group, we compete with both the leading jet engine and aircraft component OEMs and a large number of machining, fabrication, distribution and repair companies, some of which have greater financial and other resources than we do.  Competition is based mainly on price, product performance, service and technical capability.

Competition for the repair and overhaul of jet engine and aircraft components comes from three principal sources: OEMs, major commercial airlines and other independent service companies.  Some of these competitors have greater financial and other resources than we do.  Some major commercial airlines own and operate their own service centers and sell repair and overhaul services to other aircraft operators.  Foreign airlines that provide repair and overhaul services typically provide these services for their own aircraft components and for third parties.  OEMs also maintain service centers that provide repair and overhaul services for the components they manufacture.  Other independent service organizations also compete for the repair and overhaul business of other users of aircraft components.  We believe that the principal competitive factors in the repair and overhaul market are quality, turnaround time, overall customer service and price.

Our Electronic Technologies Group competes with several large and small domestic and foreign competitors, some of which have greater financial and other resources than we do.  The markets for our electronic products are niche markets with several competitors where competition is based mainly on design, technology, quality, price, service and customer satisfaction.

We purchase a variety of raw materials, primarily consisting of high temperature alloy sheet metal and castings, forgings, pre-plated metals and electrical components from various vendors.  The materials used by our operations are generally available from a number of sources and in sufficient quantities to meet current requirements subject to normal lead times. We are subject to rules promulgated by the Securities Exchange Commission pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act regarding the use of certain materials (tantalum, tin, gold and tungsten), known as conflict minerals, which are mined from the Democratic Republic of the Congo and adjoining countries. These rules may impose additional costs and may introduce new risks related to our ability to verify the origin of any conflict minerals used in our products.

Our total backlog of unshipped orders was $654 million as of October 31, 2017 as compared to $497 million as of October 31, 2016. The majority of our backlog of orders as of October 31, 2017 is expected to be delivered during fiscal 2018. The Flight Support Group's backlog of unshipped orders was $236 million as of October 31, 2017 as compared to $212 million as of October 31, 2016.  This backlog excludes forecasted shipments for certain contracts of the Flight Support Group pursuant to which customers provide only estimated annual usage and not firm purchase orders.  Our backlogs within the Flight Support Group are typically short-lead in nature with many product orders being received within the month of shipment. The increase in the Flight Support Group's backlog is principally related to the backlog of the businesses acquired during fiscal 2017. Additionally, the Flight Support Group's increase reflects increased orders at one of our businesses that manufactures advanced niche components and complex composite assemblies for commercial aviation, defense and space applications. The Electronic Technologies Group's backlog of unshipped orders was $418 million as of October 31, 2017 as compared to $285 million as of October 31, 2016. The increase in the Electronic Technologies Group's backlog is principally related to the backlog of a business acquired during fiscal 2017. Additionally, the Electronic Technologies Group's increase reflects increased orders at one of our businesses that designs and produces mission-extending, crashworthy and ballistically self-sealing auxiliary fuel systems for military rotorcraft and at a subsidiary that designs and provides power conversion products principally serving the defense, space and aviation industries. See Note 2, Acquisitions, of the Notes to Consolidated Financial Statements for additional information regarding our fiscal 2017 acquisitions.

The FAA regulates the manufacture, repair and operation of all aircraft and aircraft parts operated in the United States.  Its regulations are designed to ensure that all aircraft and aviation equipment are continuously maintained in proper condition to ensure safe operation of the aircraft.  Similar rules apply in other countries.  All aircraft must be maintained under a continuous condition monitoring program and must periodically undergo thorough inspection and maintenance.  The inspection, maintenance and repair procedures for the various types of aircraft and equipment are prescribed by regulatory authorities and can be performed only by certified repair facilities utilizing certified technicians.  Certification and conformance is required prior to installation of a part on an aircraft.  Aircraft operators must maintain logs concerning the utilization and condition of aircraft engines, life-limited engine parts and airframes.  In addition, the FAA requires that various maintenance routines be performed on aircraft engines, some engine parts, and airframes at regular intervals based on cycles or flight time.  Engine maintenance must also be performed upon the occurrence of certain events, such as foreign object damage in an aircraft engine or the replacement of life-limited engine parts.  Such maintenance usually requires that an aircraft engine be taken out of service.  Our operations may in the future be subject to new and more stringent regulatory requirements.  In that regard, we closely monitor the FAA and industry trade groups in an attempt to understand how possible future regulations might impact us.  Our businesses which sell defense products directly to the U.S. Government or for use in systems delivered to the U.S. Government can be subject to

various laws and regulations governing pricing and other factors.

There has been no material adverse effect to our consolidated financial statements as a result of these government regulations.

Our operations are subject to extensive, and frequently changing, federal, state and local environmental laws and substantial related regulation by government agencies, including the Environmental Protection Agency.  Among other matters, these regulatory authorities impose requirements that regulate the operation, handling, transportation and disposal of hazardous materials; protect the health and safety of workers; and require us to obtain and maintain licenses and permits in connection with our operations.  This extensive regulatory framework imposes significant compliance burdens and risks on us.  Notwithstanding these burdens, we believe that we are in material compliance with all federal, state and local environmental laws and regulations governing our operations.

There has been no material adverse effect to our consolidated financial statements as a result of these environmental regulations.

We are also subject to a variety of other regulations including work-related and community safety laws.  The Occupational Safety and Health Act of 1970 mandates general requirements for safe workplaces for all employees and established the Occupational Safety and Health Administration ("OSHA") in the Department of Labor.  In particular, OSHA provides special procedures and measures for the handling of certain hazardous and toxic substances.  In addition, specific safety standards have been promulgated for workplaces engaged in the treatment, disposal or storage of hazardous waste.  Requirements under state law, in some circumstances, may mandate additional measures for facilities handling materials specified as extremely dangerous.  We believe that our operations are in material compliance with OSHA's health and safety requirements.

Our business, financial condition, operating results and cash flows may be impacted by a number of factors, many of which are beyond our control, including those set forth below and elsewhere in this Annual Report on Form 10-K, any one of which may cause our actual results to differ materially from anticipated results:

     General global industry and economic conditions that affect the aviation industry also affect our business.  We are subject to macroeconomic cycles and when recessions occur, we may experience reduced orders, payment delays, supply chain disruptions or other factors as a result of the economic challenges faced by our customers, prospective customers and suppliers.  Further, the aviation industry has historically been subject to downward cycles from time to time which reduce the overall demand for jet engine and aircraft component replacement parts and repair and overhaul services, and such downward cycles result in lower sales and greater credit risk.  Demand for commercial air travel can be influenced by airline industry profitability, world trade policies, government-to-government relations, terrorism, disease outbreaks, environmental constraints imposed upon aircraft operations, technological changes, price and other competitive factors.  These global industry and economic conditions may have a material adverse effect on our business, financial condition and results of operations.

Governmental agencies throughout the world, including the FAA, highly regulate the manufacture, repair and overhaul of aircraft parts and accessories.  We include, with the replacement parts that we sell to our customers, documentation certifying that each part complies with applicable regulatory requirements and meets applicable standards of airworthiness established by the FAA or the equivalent regulatory agencies in other countries.  In addition, our repair and overhaul operations are subject to certification pursuant to regulations established by the FAA.  Specific regulations vary from country to country, although compliance with FAA requirements generally satisfies regulatory requirements in other countries.  The revocation or suspension of any of our material authorizations or approvals would have an adverse effect on our business, financial condition and results of operations.  New and more stringent government regulations, if adopted and enacted, could have an adverse effect on our business, financial condition and results of operations.  In addition, certain product sales to foreign countries of our Electronic Technologies Group and Flight Support Group require approval or licensing from the United States ("U.S.") government.  Denial of export licenses could reduce our sales to those countries and could have a material adverse effect on our business.

Pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act, the Securities and Exchange Commission promulgated disclosure requirements regarding the use of certain minerals (tantalum, tin, gold and tungsten), known as conflict minerals, which are mined from the Democratic Republic of the Congo or one of its adjoining countries. There are costs associated with complying with the disclosure requirements, such as costs related to determining the source of certain minerals used in our products, as well as costs of possible changes to products, processes, or sources of supply as a consequence of such verification activities. Given the complexity of our supply chain, we may not be able to ascertain the origin of these minerals used in our products in a timely manner, which could cause some of our customers to disqualify us as a supplier to the extent we are unable to certify our products are conflict mineral free. Additionally, the rule could affect sourcing at competitive prices and availability in sufficient quantities of such minerals used in our manufacturing processes for certain products.

Our Flight Support Group designs and manufactures jet engine and aircraft component replacement parts and also repairs, overhauls and distributes jet engine and aircraft components.  If aircraft or engines for which we offer replacement parts or supply repair and overhaul services are retired and there are fewer aircraft that require these parts or services, our revenues may decline.

In fiscal 2017, approximately 64% of the net sales of our Electronic Technologies Group were derived from the sale of defense, commercial and defense satellite and spacecraft components, and homeland security products.  A decline in defense, space or homeland security budgets or additional restrictions imposed by the U.S. government on sales of products or services to foreign military agencies could lower sales of our products and services.

We market our products and services to approximately 110 countries, with approximately 34% of our consolidated net sales in fiscal 2017 derived from sales to foreign customers.  We expect that sales to foreign customers will continue to account for a significant portion of our revenues in the foreseeable future.  As a result, we are subject to risks of doing business internationally, including the following:

While the impact of these factors is difficult to predict, any one or more of these factors may have a material adverse effect on our business, financial condition and results of operations.

We face significant competition in each of our businesses.

Flight Support Group

Electronic Technologies Group

The aviation aftermarket supply industry is highly fragmented, has several highly visible leading companies, and is characterized by intense competition.  Some of our OEM competitors have greater name recognition than HEICO, as well as complementary lines of business and financial, marketing and other resources that HEICO does not have.  In addition, OEMs, aircraft maintenance providers, leasing companies and FAA-certificated repair facilities may attempt to bundle their services and product offerings in the supply industry, thereby significantly increasing industry competition.  Moreover, our smaller competitors may be able to offer more attractive pricing of parts as a result of lower labor costs or other factors.  A variety of potential actions by any of our competitors, including a reduction of product prices or the establishment by competitors of long-term relationships with new or existing customers, could have a material adverse effect on our business, financial condition and results of operations.  Competition typically intensifies during cyclical downturns in the aviation industry, when supply may exceed demand.  We may not be able to continue to compete effectively against present or future competitors, and competitive pressures may have a material adverse effect on our business, financial condition and results of operations.

The aviation, defense, space, medical, telecommunications and electronics industries are constantly undergoing development and change and, accordingly, new products, equipment and methods of repair and overhaul service are likely to be introduced in the future.  In addition to manufacturing electronic and electro-optical equipment and selected aerospace and defense components for OEMs and the U.S. government and repairing jet engine and aircraft components, we re-design sophisticated aircraft replacement parts originally developed by OEMs so that we can offer the replacement parts for sale at substantially lower prices than those manufactured by the OEMs.  Consequently, we devote substantial resources to research and product development.  Technological development poses a number of challenges and risks, including the following:

In addition, we may not be able to successfully develop new products, equipment or methods of repair and overhaul service, and the failure to do so could have a material adverse effect on our business, financial condition and results of operations.

A key element of our strategy is growth through the acquisition of additional companies.  Our acquisition strategy is affected by and poses a number of challenges and risks, including the following:

We may not be able to successfully execute our acquisition strategy, and the failure to do so could have a material adverse effect on our business, financial condition and results of operations.

As a result of our acquisitions, goodwill and intangible assets represent a significant portion of our total assets. As of October 31, 2017 and 2016, goodwill and intangible assets, net of amortization, accounted for approximately 64% and 62% of our total assets, respectively. We test our goodwill and intangible assets for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that the carrying amount of such assets may not be fully recoverable. We may not realize the full value of our goodwill and intangible assets, and to the extent that impairment has occurred, we would be required to recognize the impaired portion of such assets in our earnings. An impairment of a significant portion of such assets could have a material adverse effect on our business, financial condition and results of operations.

Our business is affected by the availability and price of the raw materials and component parts that we use to manufacture our products.  Our ability to manage inventory and meet delivery requirements may be constrained by our suppliers' ability to adjust delivery of long-lead time products during times of volatile demand.  The supply chains for our business could also be disrupted by external events such as natural disasters, extreme weather events, labor disputes, governmental actions and legislative or regulatory changes.  As a result, our suppliers may fail to perform according to specifications when required and we may be unable to identify alternate suppliers or to otherwise mitigate the consequences of their non-performance.  Transitions to new suppliers may result in significant costs and delays, including those related to the required recertification of parts obtained from new suppliers with our customers and/or regulatory agencies.  Our inability to fill our supply needs could jeopardize our ability to fulfill obligations under customer contracts, which could result in reduced revenues and profits, contract penalties or terminations, and damage to customer relationships.  Further, increased costs of such raw materials or components could reduce our profits if we were unable to pass along such price increases to our customers.

The costs to meet customer specifications and requirements could result in us having to spend more to design or manufacture products and this could reduce our profit margins on current contracts or those we obtain in the future.

Our jet engine and aircraft component replacement parts and repair and overhaul services expose our business to potential liabilities for personal injury or death as a result of the failure of an aircraft component that we have designed, manufactured or serviced.  While we maintain liability insurance to protect us from future product liability claims, an uninsured or partially insured claim, or a claim for which third-party indemnification is not available, could have a material adverse effect on our business, financial condition and results of operations. Additionally, our customers typically require us to maintain substantial insurance coverage at commercially reasonable rates and our inability to obtain insurance coverage at commercially reasonable rates could have a material adverse effect on our business.

Our operations and facilities are subject to a number of federal, state and local environmental laws and regulations, which govern, among other things, the discharge of hazardous materials into the air and water as well as the handling, storage and disposal of hazardous materials.  Pursuant to various environmental laws, a current or previous owner or operator of real property may be liable for the costs of removal or remediation of hazardous materials.  Environmental laws typically impose liability whether or not the owner or operator knew of, or was responsible for, the presence of hazardous materials.  Although management believes that our operations and facilities are in material compliance with environmental laws and regulations, future changes in them or interpretations thereof or the nature of our operations may require us to make significant additional capital expenditures to ensure compliance in the future.

We carry limited specific environmental insurance, thus, losses could occur for uninsurable or uninsured risks or in amounts in excess of existing insurance coverage. The occurrence of an event that is not covered in full or in part by insurance could have a material adverse effect on our business, financial condition and results of operations.

Several of our facilities, as a result of their locations, could be subject to a catastrophic loss caused by hurricanes, tornadoes, earthquakes, floods, fire, power loss, telecommunication and information systems failure, political unrest or similar events.  Our corporate headquarters

and facilities located in Florida are particularly susceptible to hurricanes, storms, tornadoes or other natural disasters that could disrupt our operations, delay production and shipments, and result in large expenses to repair or replace the facility or facilities.  Should insurance or other risk transfer mechanisms, such as our existing disaster recovery and business continuity plans, be insufficient to recover all costs, we could experience a material adverse effect on our business, financial condition and results of operations.

We rely on information technology systems, some of which are managed by third parties, to process, transmit and store electronic information, and to manage or support a variety of critical business processes and activities. We also collect and store sensitive data, including confidential business information and personal data. These systems may be susceptible to damage, disruptions or shutdowns due to attacks by computer hackers, computer viruses, employee error or malfeasance, power outages, hardware failures, telecommunication or utility failures, catastrophes or other unforeseen events. In addition, security breaches of our systems could result in the misappropriation or unauthorized disclosure of confidential information or personal data belonging to us or to our employees, partners, customers or suppliers. Any such events could disrupt our operations, delay production and shipments, result in defective products or services, damage customer relationships and our reputation and result in legal claims or proceedings that could have a material adverse effect on our business, financial condition and results of operations.

We file income tax returns in the U.S. federal jurisdiction, multiple state jurisdictions and certain jurisdictions outside the U.S.  In fiscal 2017, our effective tax rate was 30.3%.  Our future effective tax rate may be adversely affected by a number of factors, including the following:

Any significant increase in our future effective tax rates could have a material adverse effect on net income for future periods.

Recently, U.S. Congress has proposed comprehensive tax reform legislation that could materially affect the tax aspects of our business and the industries in which we compete. Such tax reform may be substantially revised through the legislative process, or may never be enacted. To the extent that tax reforms, if any, have a negative effect on us or the industries we serve, these changes may have a material adverse effect on our business, financial condition and results of operations.

We have experienced rapid growth in recent periods and intend to continue to pursue an aggressive growth strategy, both through acquisitions and internal expansion of products and services.  Our growth to date has placed, and could continue to place, significant demands on our administrative, operational and financial resources.  We may not be able to grow effectively or manage our growth successfully, and the failure to do so could have a material adverse effect on our business, financial condition and results of operations.

Our success substantially depends on the performance, contributions and expertise of our senior management team led by Laurans A. Mendelson, our Chairman and Chief Executive Officer, and Eric A. Mendelson and Victor H. Mendelson, our Co-Presidents. Technical employees are also critical to our research and product development, as well as our ability to continue to re-design sophisticated products of OEMs in order to sell competing replacement parts at substantially lower prices than those manufactured by the OEMs.  The loss of the services of any of our executive officers or other key employees or our inability to continue to attract or retain the necessary personnel could have a material adverse effect on our business, financial condition and results of operations.

As of December 19, 2017, collectively our executive officers and entities controlled by them, the HEICO Savings and Investment Plan (our 401(k) Plan) and members of the Board of Directors beneficially owned approximately 22% of our outstanding Common Stock and approximately 6% of our outstanding Class A Common Stock.  Accordingly, they will be able to substantially influence the election of the Board of Directors and control our business, policies and affairs, including our position with respect to proposed business combinations and attempted takeovers.

None.

We own or lease a number of facilities, which are utilized by our Flight Support Group ("FSG"), Electronic Technologies Group ("ETG") and corporate offices.  As of October 31, 2017, all of the facilities listed below were in good operating condition, well maintained and in regular use.  We believe that our existing facilities are sufficient to meet our operational needs for the foreseeable future.  Summary information on the facilities utilized within the FSG, ETG and our corporate offices to support their principal operating activities is as follows:

We are involved in various legal actions arising in the normal course of business.  Based upon the Company's and our legal counsel's evaluations of any claims or assessments, management is of the opinion that the outcome of these matters will not have a material effect on our results of operations, financial position or cash flows.

Not applicable.

Our Class A Common Stock and Common Stock are listed and traded on the New York Stock Exchange ("NYSE") under the symbols "HEI.A" and "HEI," respectively.  The following tables set forth, for the periods indicated, the high and low share prices for our Class A Common Stock and our Common Stock as reported on the NYSE, as well as the amount of cash dividends paid per share during such periods.

In March 2017, the Company's Board of Directors declared a 5-for-4 stock split on both classes of the Company's common stock. The stock split was effected as of April 19, 2017 in the form of a 25% stock dividend distributed to shareholders of record as of April 7, 2017. All applicable share and per share information has been adjusted retrospectively to give effect to the fiscal 2017 5-for-4 stock split.

As of December 19, 2017, there were 340 holders of record of our Class A Common Stock and 330 holders of record of our Common Stock.

The following graph and table compare the total return on $100 invested in HEICO Common Stock and HEICO Class A Common Stock with the total return on $100 invested in the NYSE Composite Index and the Dow Jones U.S. Aerospace Index for the five-year period from October 31, 2012 through October 31, 2017.  The NYSE Composite Index measures the performance of all common stocks listed on the NYSE.  The Dow Jones U.S. Aerospace Index is comprised of large companies which make aircraft, major weapons, radar and other defense equipment and systems as well as providers of satellites and spacecraft used for defense purposes.  The total returns include the reinvestment of cash dividends.

The following graph and table compare the total return on $100 invested in HEICO Common Stock since October 31, 1990 using the same indices shown on the five-year performance graph above.  October 31, 1990 was the end of the first fiscal year following the

date the current executive management team assumed leadership of the Company.  No Class A Common Stock was outstanding as of October 31, 1990.  As with the five-year performance graph, the total returns include the reinvestment of cash dividends.

We have historically paid semi-annual cash dividends on both our Class A Common Stock and Common Stock. In July 2017, we paid our 78th consecutive semi-annual cash dividend since 1979 of $.08 per share, which represented an 11% increase over the prior semi-annual cash dividend of $.072 per share paid in January 2017. Additionally, our 77th consecutive semi-annual cash dividend paid in January 2017 represented a 13% increase over the $.064 per share semi-annual cash dividend paid in July 2016. Our Board of Directors will continue to review our dividend policy and will regularly evaluate whether dividends should be paid in cash or stock, as well as what amounts should be paid. Our ability to pay dividends could be affected by future business performance, liquidity, capital needs, alternative investment opportunities and loan covenants under our revolving credit facility.

In December 2017, our Board of Directors declared a regular semi-annual cash dividend of $.0875 per share payable in January 2018. This cash dividend represents a 9% increase over the prior semi-annual per share amount of $.08. Further, in December 2017, our Board of Directors declared a 5-for-4 stock split on both classes of our common stock. We expect to distribute the additional shares to shareholders in January 2018. None of the applicable share and per share information in this annual report on Form 10-K has been adjusted retrospectively to give effect to the pending 5-for-4 stock split. See Note 17, Subsequent Events, of the Notes to Consolidated Financial Statements for further information regarding our pending fiscal 2018 stock split.

There were no purchases of our equity securities during the fourth quarter of fiscal 2017.

There were no unregistered sales of our equity securities during fiscal 2017.

Unless otherwise noted, the purchase price of each of the above referenced acquisitions was paid in cash, principally using proceeds from our revolving credit facility. The aggregate

amount paid in cash for acquisitions was $418.3 million, $263.8 million and $166.8 million in fiscal 2017, 2016 and 2015, respectively.    

We believe that the following are our most critical accounting policies, which require management to make judgments about matters that are inherently uncertain.

Assumptions utilized to determine fair value in connection with business combinations, contingent consideration arrangements and in goodwill and intangible assets impairment tests are highly judgmental.  If there is a material change in such assumptions or if there is a material change in the conditions or circumstances influencing fair value, we could be required to recognize a material impairment charge.  See Item 1A., Risk Factors , for a list of factors which may cause our actual results to differ materially from anticipated results.

Revenue Recognition

Revenue from the sale of products and the rendering of services is recognized when title and risk of loss passes to the customer, which is generally at the time of shipment.  Revenue from certain fixed price contracts for which costs can be dependably estimated is recognized on the percentage-of-completion method, measured by the percentage of costs incurred to date to estimated total costs for each contract.  This method is used because management considers costs incurred to be the best available measure of progress on these contracts.  Revisions in cost estimates as contracts progress have the effect of increasing or decreasing profits in the period of revision.  Revisions in cost estimates may be caused by factors such as the price or availability of raw materials and component parts or variations in the amount of labor required and/or the materials necessary to meet customer specifications and requirements. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. The percentage of our net sales recognized under the percentage-of-completion method was approximately 3%, 3% and 4% in fiscal 2017, 2016 and 2015, respectively.  Changes in estimates pertaining to percentage-of-completion contracts did not have a material or significant effect on net income or net income per share in fiscal 2017, 2016 and 2015.

For fixed price contracts in which costs cannot be dependably estimated, revenue is recognized on the completed-contract method.  A contract is considered complete when all significant costs have been incurred or the item has been accepted by the customer. Progress billings and customer advances received on fixed price contracts accounted for under the completed-contract method are classified as a reduction to contract costs that are included in inventories, if any, and any remaining amount is included in accrued expenses and other current liabilities.

Valuation of Accounts Receivable

The valuation of accounts receivable requires that we set up an allowance for estimated uncollectible accounts and record a corresponding charge to bad debt expense.  We estimate

uncollectible receivables based on such factors as our prior experience, our appraisal of a customer's ability to pay, age of receivables outstanding and economic conditions within and outside of the aviation, defense, space, medical, telecommunications and electronics industries.  Actual bad debt expense could differ from estimates made.

Valuation of Inventory

Inventory is stated at the lower of cost or market, with cost being determined on the first-in, first-out or the average cost basis.  Losses, if any, are recognized fully in the period when identified.

We periodically evaluate the carrying value of inventory, giving consideration to factors such as its physical condition, sales patterns and expected future demand in order to estimate the amount necessary to write down any slow moving, obsolete or damaged inventory.  These estimates could vary significantly from actual amounts based upon future economic conditions, customer inventory levels, or competitive factors that were not foreseen or did not exist when the estimated write-downs were made.

In accordance with industry practice, all inventories are classified as a current asset including portions with long production cycles, some of which may not be realized within one year.

Business Combinations

We allocate the purchase price of acquired entities to the underlying tangible and identifiable intangible assets acquired and liabilities and any noncontrolling interests assumed based on their estimated fair values, with any excess recorded as goodwill.  Determining the fair value of assets acquired and liabilities and noncontrolling interests assumed requires management's judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, asset lives and market multiples, among other items.  We determine the fair values of intangible assets acquired generally in consultation with third-party valuation advisors.

As part of the agreement to acquire certain subsidiaries, we may be obligated to pay contingent consideration should the acquired entity meet certain earnings objectives subsequent to the date of acquisition. As of the acquisition date, contingent consideration is recorded at fair value as determined through the use of a probability-based scenario analysis approach. Under this method, a set of discrete potential future subsidiary earnings is determined using internal estimates based on various revenue growth rate assumptions for each scenario. A probability of likelihood is then assigned to each discrete potential future earnings estimate and the resultant contingent consideration is calculated and discounted using a weighted average discount rate reflecting the credit risk of HEICO. Subsequent to the acquisition date, the fair value of such contingent consideration is measured each reporting period and any changes are recorded to selling, general and administrative ("SG&A") expenses within our Consolidated Statements of Operations. Changes in either the revenue growth rates, related earnings or the discount rate

could result in a material change to the amount of contingent consideration accrued. As of October 31, 2017, 2016 and 2015, $27.6 million, $18.9 million and $21.4 million of contingent consideration was accrued within our Consolidated Balance Sheets, respectively. During fiscal 2017, 2016 and 2015, such fair value measurement adjustments resulted in net increases to SG&A expenses of $1.1 million, $3.1 million and $.3 million, respectively. For further information regarding our contingent consideration arrangements, see Note 7, Fair Value Measurements, of the Notes to Consolidated Financial Statements.

Valuation of Goodwill and Other Intangible Assets

We test goodwill for impairment annually as of October 31, or more frequently if events or changes in circumstances indicate that the carrying amount of goodwill may not be fully recoverable.  In evaluating the recoverability of goodwill, we compare the fair value of each of our reporting units to its carrying value to determine potential impairment.  If the carrying value of a reporting unit exceeds its fair value, the implied fair value of that reporting unit's goodwill is to be calculated and an impairment loss is recognized in the amount by which the carrying value of the reporting unit's goodwill exceeds its implied fair value, if any.  The fair values of our reporting units were determined using a weighted average of a market approach and an income approach.  Under the market approach, fair values are estimated using published market multiples for comparable companies. We calculate fair values under the income approach by taking estimated future cash flows that are based on internal projections and other assumptions deemed reasonable by management and discounting them using an estimated weighted average cost of capital.  Based on the annual goodwill impairment test as of October 31, 2017, 2016 and 2015, we determined there was no impairment of our goodwill.  The fair value of each of our reporting units as of October 31, 2017 significantly exceeded its carrying value.

We test each non-amortizing intangible asset (principally trade names) for impairment annually as of October 31, or more frequently if events or changes in circumstances indicate that the asset might be impaired. To derive the fair value of our trade names, we utilize an income approach, which relies upon management's assumptions of royalty rates, projected revenues and discount rates.  We also test each amortizing intangible asset for impairment if events or circumstances indicate that the asset might be impaired.  The test consists of determining whether the carrying value of such assets will be recovered through undiscounted expected future cash flows.  If the total of the undiscounted future cash flows is less than the carrying amount of those assets, we recognize an impairment loss based on the excess of the carrying amount over the fair value of the assets.  The determination of fair value requires us to make a number of estimates, assumptions and judgments of underlying factors such as projected revenues and related earnings as well as discount rates. Based on the intangible impairment tests conducted, we did not recognize any impairment losses in fiscal 2017, 2016 and 2015.

The following table sets forth the results of our operations, net sales and operating income by segment and the percentage of net sales represented by the respective items in our Consolidated Statements of Operations (in thousands) :

Net Sales

Our net sales in fiscal 2017 increased by 11% to a record $1,524.8 million, as compared to net sales of $1,376.3 million in fiscal 2016. The increase in consolidated net sales reflects an increase of $63.0 million (a 12% increase) to a record $574.3 million in net sales within the ETG as well as an increase of $91.7 million (a 10% increase) to a record $967.5 million in net sales within the FSG. The net sales increase in the ETG resulted from organic growth of 7% as well as net sales of $23.3 million contributed by our fiscal 2017 and 2016 acquisitions. The ETG's organic growth is mainly attributed to increased demand for our space, aerospace and other electronics products resulting in net sales increases of $14.7 million, $12.6 million and $9.3 million, respectively. The net sales increase in the FSG reflects net sales of $49.0 million contributed by our fiscal 2017 acquisitions as well as organic growth of 5%. The FSG's organic growth is principally attributed to increased demand and new product offerings within our aftermarket replacement parts and repair and overhaul parts and services product lines, resulting in net sales increases of $39.8 million and $19.1 million, respectively. These increases were partially offset by $16.2 million of lower organic net sales from our specialty products product line principally related to certain aerospace, industrial and defense products. Sales price changes were not a significant contributing factor to the FSG and ETG net sales growth in fiscal 2017.

Our net sales in fiscal 2017 and 2016 by market consisted of approximately 53% and 52%, respectively, from the commercial aviation industry, 34% in both periods from the defense and space industries, and 13% and 14%, respectively, from other industrial markets including medical, electronics and telecommunications.

Gross Profit and Operating Expenses

Our consolidated gross profit margin increased to 37.7% in fiscal 2017 as compared to 37.5% in fiscal 2016, principally reflecting an increase of .9% in the ETG's gross profit margin, partially offset by a .3% decrease in the FSG's gross profit margin. The increase in the ETG's gross profit margin is principally attributed to increased net sales and a more favorable product mix for certain aerospace products. The decrease in the FSG's gross profit margin is attributed to the previously mentioned decrease in net sales and a less favorable product mix within our specialty products product line partially offset by increased net sales and a more favorable product mix within our aftermarket replacement parts and repair and overhaul parts and services product lines. Total new product research and development ("R&D") expenses included within our consolidated cost of sales increased to $46.5 million in fiscal 2017 compared to $44.7 million in fiscal 2016.

Our consolidated SG&A expenses were $268.1 million and $250.1 million in fiscal 2017 and 2016, respectively. The increase in consolidated SG&A expenses principally reflects $13.6 million attributable to the fiscal 2017 acquisitions, $4.3 million of higher performance-based compensation expense and a $2.9 million impact from foreign currency transaction adjustments

on borrowings denominated in Euros under our revolving credit facility, partially offset by $3.1 million of acquisition costs recorded in fiscal 2016 associated with a fiscal 2016 acquisition.

Our consolidated SG&A expenses as a percentage of net sales decreased to 17.6% in fiscal 2017, down from 18.2% in fiscal 2016. The decrease in consolidated SG&A expenses as a percentage of net sales principally reflects an aggregate .8% impact from efficiencies realized from the benefit of our net sales growth on relatively consistent period-over-period SG&A expenses and the aforementioned decrease in acquisition costs, partially offset by a .2% impact from the previously mentioned foreign currency transaction adjustments.

Operating Income

Our consolidated operating income increased by 16% to a record $306.7 million in fiscal 2017, up from $265.3 million in fiscal 2016. The increase in consolidated operating income principally reflects a $31.4 million increase (a 25% increase) to a record $157.5 million in operating income of the ETG as well as a $15.9 million increase (a 10% increase) to a record $179.3 million in operating income of the FSG. Additionally, our consolidated operating income was unfavorably impacted by a $5.3 million increase in corporate expenses principally due to the previously mentioned foreign currency transaction adjustments as well as higher operating costs in line with and to support the growth of our overall business. The increase in operating income of the ETG is principally attributed to the previously mentioned net sales growth and improved gross profit margin as well as the aforementioned favorable impact of SG&A efficiencies and decrease in acquisition costs. The increase in operating income of the FSG is principally attributed to the previously mentioned net sales growth partially offset by an increase in performance-based compensation expense and the less favorable gross profit margin.

Our consolidated operating income as a percentage of net sales increased to 20.1% in fiscal 2017, up from 19.3% in fiscal 2016. The increase principally reflects an increase in the ETG's operating income as a percentage of net sales to 27.4% in fiscal 2017, up from 24.7% in fiscal 2016, partially offset by a slight decrease in the FSG's operating income as a percentage of net sales to 18.5% in fiscal 2017, down from 18.7% in fiscal 2016. Additionally, our consolidated operating income as a percentage of net sales was unfavorably impacted by a .2% impact from the previously mentioned foreign currency transaction adjustments. The increase in the ETG's operating income as a percentage of net sales is principally attributed to the previously mentioned, SG&A efficiencies, improved gross profit margin, and decrease in acquisition costs.

Interest Expense

Interest expense increased to $9.8 million in fiscal 2017 from $8.3 million in fiscal 2016. The increase was principally due to higher interest rates partially offset by a lower weighted average balance outstanding under our revolving credit facility.

Other Income (Expense)

Other income (expense) in fiscal 2017 and 2016 was not material.

Income Tax Expense

Our effective tax rate in fiscal 2017 decreased to 30.3% from 31.5% in fiscal 2016. The decrease principally reflects the favorable impact of higher tax-exempt unrealized gains in the cash surrender values of life insurance policies related to the HEICO Corporation Leadership Compensation Plan and a $3.1 million discrete income tax benefit related to stock option exercises resulting from the adoption of Accounting Standards Update 2016-09, "Improvements to Employee Share-Based Payment Accounting," in the first quarter of fiscal 2017 (see New Accounting Pronouncements below). These decreases were partially offset by the benefit recognized in fiscal 2016 from the retroactive and permanent extension of the U.S. federal R&D tax credit that resulted in the recognition of additional income tax credits for qualified R&D activities related to the last ten months of fiscal 2015 and a less favorable benefit in fiscal 2017 from the foreign tax rate differential associated with the undistributed earnings of a fiscal 2015 acquisition.

Net Income Attributable to Noncontrolling Interests

Net income attributable to noncontrolling interests relates to the 20% noncontrolling interest held by Lufthansa Technik AG in HEICO Aerospace and the noncontrolling interests held by others in certain subsidiaries of the FSG and ETG. Net income attributable to noncontrolling interests was $21.7 million in fiscal 2017 compared to $20.0 million in fiscal 2016. The increase in fiscal 2017 reflects higher net income of certain subsidiaries of the FSG and ETG in which noncontrolling interests are held, inclusive of a fiscal 2017 acquisition.

Net Income Attributable to HEICO

Net income attributable to HEICO increased by 19% to a record $186.0 million, or $2.14 per diluted share, in fiscal 2017, up from $156.2 million, or $1.83 per diluted share, in fiscal 2016, principally reflecting the previously mentioned increased net sales and operating income.

Outlook

As we look ahead to fiscal 2018, we anticipate net sales growth within the FSG's commercial aviation and defense product lines. We also expect growth within the ETG, principally driven by demand for the majority of our products. During fiscal 2018, we will continue our commitments to developing new products and services, further market penetration, and an aggressive acquisition strategy while maintaining our financial strength and flexibility. Overall, we are targeting growth in fiscal 2018 full year net sales and net income over fiscal 2017 levels. This outlook excludes the impact of additional acquired businesses, if any.

Net Sales

Our net sales in fiscal 2016 increased by 16% to a record $1,376.3 million, as compared to net sales of $1,188.6 million in fiscal 2015. The increase in consolidated net sales reflects an increase of $120.3 million (a 31% increase) to a record $511.3 million in net sales within the ETG as well as an increase of $66.2 million (an 8% increase) to a record $875.9 million in net sales within the FSG. The net sales increase in the ETG reflects net sales of $107.3 million contributed by our fiscal 2016 and 2015 acquisitions as well as organic growth of 4%. The ETG's organic growth resulted mainly from an aggregate net sales increase of $17.2 million attributed to higher demand from certain space, medical and other electronics products, partially offset by a $3.2 million net sales decrease from lower demand for certain defense products. The net sales increase in the FSG reflects net sales of $40.6 million contributed by our fiscal 2015 acquisitions as well as organic growth of 3%. The FSG's organic growth is principally attributed to increased demand and new product offerings within our aftermarket replacement parts and specialty products lines, resulting in net sales increases of $22.6 million and $10.9 million, respectively. These increases were partially offset by $7.9 million of lower organic net sales from our repair and overhaul parts and services product line. Our repair and overhaul parts and services product line was adversely impacted by the mix of products repaired during fiscal 2016, which required less extensive repair and overhaul services, as well as softer demand from our South American market. The FSG experienced organic revenue growth of 6% in fiscal 2016 excluding our repair and overhaul parts and services product line. Sales price changes were not a significant contributing factor to the FSG and ETG net sales growth in fiscal 2016.

Our net sales in fiscal 2016 and 2015 by market consisted of approximately 52% and 57%, respectively, from the commercial aviation industry, 34% and 27%, respectively, from the defense and space industries, and 14% and 16%, respectively, from other industrial markets including medical, electronics and telecommunications.

Gross Profit and Operating Expenses

Our consolidated gross profit margin increased to 37.5% in fiscal 2016 as compared to 36.5% in fiscal 2015, principally reflecting an increase of .9% in the FSG's gross profit margin, partially offset by a .5% decrease in the ETG's gross profit margin. The increase in the FSG's gross profit margin is principally attributed to increased net sales and a more favorable product mix within our aftermarket replacement parts and specialty products product lines, partially offset by decreased net sales and a less favorable product mix within our repair and overhaul parts and services product line. The decrease in the ETG's gross profit margin is principally attributed to a less favorable product mix for certain space products. Total new product R&D expenses included within our consolidated cost of sales increased to $44.7 million in fiscal 2016 compared to $38.7 million in fiscal 2015.

Our consolidated SG&A expenses were $250.1 million and $204.5 million in fiscal 2016 and 2015, respectively. The increase in consolidated SG&A expenses principally reflects $21.8

million attributable to the fiscal 2016 and 2015 acquisitions, inclusive of $3.1 million of acquisition costs associated with a fiscal 2016 acquisition, $9.1 million of higher performance-based compensation expense, $3.1 million attributable to changes in the estimated fair value of accrued contingent consideration associated with a prior year acquisition, inclusive of foreign currency transaction adjustments, and a $2.4 million impact from foreign currency transaction adjustments on borrowings denominated in Euros under our revolving credit facility.

Our consolidated SG&A expenses as a percentage of net sales were 18.2% and 17.2% in fiscal 2016 and 2015, respectively. The increase in consolidated SG&A expenses as a percentage of net sales principally reflects a .5% impact from higher performance-based compensation expense and a .2%, .2% and .2% impact from the aforementioned changes in the estimated fair value of accrued contingent consideration, foreign currency transaction adjustments and acquisition costs, respectively.

Operating Income

Our consolidated operating income in fiscal 2016 increased by 16% to a record $265.3 million, up from $229.7 million in fiscal 2015. As a percentage of net sales, our consolidated operating income was 19.3% in both fiscal 2016 and 2015. The increase in consolidated operating income is primarily attributed to a $27.2 million increase (a 28% increase) to a record $126.0 million in operating income of the ETG as well as a $13.6 million increase (a 9% increase) to a record $163.4 million in operating income of the FSG, partially offset by a $5.1 million increase in corporate expenses principally reflecting higher performance-based compensation expense and the previously mentioned foreign currency transaction adjustments on borrowings denominated in Euros. The increase in operating income of the ETG is mainly attributed to the previously mentioned net sales growth, partially offset by a $6.4 million and $5.2 million increase in amortization expense of intangible assets and performance-based compensation expense, respectively, in addition to the impact from the previously mentioned acquisition costs. The increase in operating income of the FSG is mainly attributed to the previously mentioned net sales growth and improved gross profit margin, partially offset by a $4.4 million increase in performance-based compensation expense, the previously mentioned changes in the estimated fair value of accrued contingent consideration and a $3.0 million increase in amortization expense of intangible assets.

Interest Expense

Interest expense increased to $8.3 million in fiscal 2016 from $4.6 million in fiscal 2015. The increase was due to a higher weighted average balance outstanding under our revolving credit facility associated with our fiscal 2016 and 2015 acquisitions as well as higher interest rates.

Other Expense

Other expense in fiscal 2016 and 2015 was not material.

Income Tax Expense

Our effective tax rate in fiscal 2016 decreased to 31.5% from 31.7% in fiscal 2015. The decrease principally reflects the benefits recognized in fiscal 2016 of a larger income tax credit for qualified R&D activities resulting from the permanent extension of the U.S. federal R&D tax credit in December 2015 and a lower effective state tax rate driven by certain apportionment updates recognized upon the amendment of certain prior year tax returns in fiscal 2016. These decreases were partially offset by the benefits recognized in fiscal 2015 from a prior year tax return amendment for additional foreign tax credits related to R&D activities at one of our foreign subsidiaries and higher net income attributable to noncontrolling interests in subsidiaries structured as partnerships. See Note 6, Income Taxes, of the Notes to Consolidated Financial Statements for a detailed analysis of the provision for income taxes.

Net Income Attributable to Noncontrolling Interests

Net income attributable to noncontrolling interests relates to the 20% noncontrolling interest held by Lufthansa Technik AG in HEICO Aerospace and the noncontrolling interests held by others in certain subsidiaries of the FSG and ETG. Net income attributable to noncontrolling interests was $20.0 million in fiscal 2016 compared to $20.2 million in fiscal 2015.

Net Income Attributable to HEICO

Net income attributable to HEICO increased by 17% to a record $156.2 million, or $1.83 per diluted share, in fiscal 2016 from $133.4 million, or $1.57 per diluted share, in fiscal 2015, principally reflecting the previously mentioned increased net sales and operating income.

We have generally experienced increases in our costs of labor, materials and services consistent with overall rates of inflation.  The impact of such increases on net income attributable to HEICO has been generally minimized by efforts to lower costs through manufacturing efficiencies and cost reductions.

Our principal uses of cash include acquisitions, capital expenditures, cash dividends, distributions to noncontrolling interests and working capital needs. Capital expenditures in fiscal 2018 are anticipated to approximate $50 million. We finance our activities primarily from our operating and financing activities, including borrowings under our revolving credit facility.

In November 2017, we entered into a new $1.3 billion Revolving Credit Facility Agreement ("New Credit Facility") with a bank syndicate, which matures in November 2022. Under certain circumstances, the maturity of the New Credit Facility may be extended for two one-year periods. The New Credit Facility also includes a feature that will allow us to increase revolving commitments under the New Credit Facility by $350 million to become a $1.65 billion facility, through increased commitments from existing lenders or the addition of new lenders. Borrowings under the New Credit Facility may be used to finance acquisitions and for working capital and other general corporate purposes, including capital expenditures. The New Credit Facility replaced the $670 million Revolving Credit Agreement (see Financing Activities below).

Borrowings under the New Credit Facility accrue interest at our election of the Base Rate or the Eurocurrency Rate, plus in each case, the Applicable Rate (based on our Total Leverage Ratio). The Base Rate for any day is a fluctuating rate per annum equal to the highest of (i) the Prime Rate; (ii) the Federal Funds Rate plus .50%; and (iii) the Eurocurrency Rate for an Interest Period of one month plus 100 basis points. The Eurocurrency Rate is the rate per annum obtained by dividing LIBOR for the applicable Interest Period by a percentage equal to 1.00 minus the daily average Eurocurrency Reserve Rate for such Interest Period, as such capitalized terms are defined in the New Credit Facility. The Applicable Rate for Eurocurrency Rate Loans ranges from 1.00% to 2.00%. The Applicable Rate for Base Rate Loans ranges from 0% to 1.00%. A fee is charged on the amount of the unused commitment ranging from .125% to .30% (depending on our Total Leverage Ratio). The New Credit Facility also includes $100 million sublimits for borrowings made in foreign currencies and for swingline borrowings, and a $50 million sublimit for letters of credit. Outstanding principal, accrued and unpaid interest and other amounts payable under the New Credit Facility may be accelerated upon an event of default, as such events are described in the New Credit Facility. The New Credit Facility is

unsecured and contains covenants that require, among other things, the maintenance of a Total Leverage Ratio and an Interest Coverage Ratio, as such capitalized terms are defined in the New Credit Facility. We were in compliance with all financial and nonfinancial covenants of the New Credit Facility as of October 31, 2017.

As of December 19, 2017, we had approximately $625 million of unused committed availability under the terms of our revolving credit facility. Based on our current outlook, we believe that net cash provided by operating activities and available borrowings under our revolving credit facility will be sufficient to fund our cash requirements for at least the next twelve months.

Operating Activities

Net cash provided by operating activities was $274.9 million in fiscal 2017 and consisted primarily of net income from consolidated operations of $207.7 million and depreciation and amortization expense of $64.8 million (a non-cash item). Net cash provided by operating activities increased by $25.7 million in fiscal 2017 from $249.2 million in fiscal 2016. The increase in net cash provided by operating activities in fiscal 2017 is principally due to a $31.5 million increase in net income from consolidated operations and a $4.5 million increase in depreciation and amortization expense (a non-cash item), partially offset by a $12.0 million increase in working capital (current assets minus current liabilities). The $12.0 million increase in working capital is principally attributed to a $33.5 million decrease in accrued expenses and other current liabilities, which mainly reflects a decrease in deferred revenue attributed to billings in excess of costs and estimated earnings on fixed price contracts for which revenue is being recognized on the percentage-of-completion method and customer deposits received in connection with both manufacturing and repair and overhaul services, partially offset by an $18.8 million decrease in accounts receivable.

Net cash provided by operating activities was $249.2 million in fiscal 2016 and consisted primarily of net income from consolidated operations of $176.2 million, depreciation and amortization expense of $60.3 million (a non-cash item) and an increase in working capital (current assets minus current liabilities) of $8.1 million. Net cash provided by operating activities increased by $76.3 million in fiscal 2016 from $172.9 million in fiscal 2015. The increase in net cash provided by operating activities in fiscal 2016 is principally due to a $36.7 million decrease in working capital, a $22.6 million increase in net income from consolidated operations and a $12.4 million increase in depreciation and amortization expense (a non-cash item). The $36.7 million decrease in working capital is principally attributed to a $36.2 million increase in accrued expenses and other current liabilities, which mainly reflects an increase in deferred revenue attributed to billings in excess of costs and estimated earnings on a fixed price contract for which revenue is being recognized on the percentage-of-completion method and customer deposits received in connection with a contract to provided repair and overhaul services, as well as a higher level of accrued performance-based compensation due to the improved consolidated operating results, and an increase in accrued customer rebates and credits.

Net cash provided by operating activities was $172.9 million in fiscal 2015 and consisted primarily of net income from consolidated operations of $153.6 million, depreciation and amortization expense of $47.9 million (a non-cash item) and a decrease in working capital (current assets minus current liabilities) of $28.7 million.

Investing Activities

Net cash used in investing activities during the three-year fiscal period ended October 31, 2017 primarily relates to several acquisitions aggregating $848.9 million, including $418.3 million in fiscal 2017, $263.8 million in fiscal 2016, and $166.8 million in fiscal 2015.  Further details on acquisitions may be found at the beginning of this Item 7 under the caption "Overview" and Note 2, Acquisitions, of the Notes to Consolidated Financial Statements.  

Capital expenditures aggregated $75.1 million over the last three fiscal years, primarily reflecting the expansion, replacement and betterment of existing production facilities and capabilities, which were generally funded using cash provided by operating activities.

Financing Activities

Net cash provided by financing activities was $175.9 million in fiscal 2017 as compared to $56.8 million in fiscal 2016 and $27.3 million in fiscal 2015. During the three-year fiscal period ended October 31, 2017, we borrowed an aggregate $837.7 million under our revolving credit facility including borrowings of $404.0 million in fiscal 2017, $260.0 million in fiscal 2016, and $173.7 million in fiscal 2015. The aforementioned borrowings were made principally to fund acquisitions. Further details on acquisitions may be found at the beginning of this Item 7 under the caption "Overview" and Note 2, Acquisitions, of the Notes to Consolidated Financial Statements. Payments on our revolving credit facility aggregated $492.9 million over the last three fiscal years, including $190.9 million in fiscal 2017, $170.0 million in fiscal 2016, and $132.0 million in fiscal 2015. For the three-year fiscal period ended October 31, 2017, we made distributions to noncontrolling interests aggregating $47.1 million and paid an aggregate $32.9 million in cash dividends.

Borrowings under our revolving credit facility in fiscal 2017, 2016 and 2015 were made under our $670 million Revolving Credit Agreement ("Prior Credit Facility") with a bank syndicate, which was amended in November 2013 to become an $800 million facility and again in April 2017 to become a $1.0 billion facility. The Prior Credit Facility was available to finance acquisitions and for working capital and general corporate purposes, including capital expenditures.

Advances under the Prior Credit Facility accrued interest at our choice of the "Base Rate" or the London Interbank Offered Rate ("LIBOR") plus the applicable margin (based on our ratio of total funded debt to earnings before interest, taxes, depreciation and amortization, noncontrolling interests and non-cash charges, or "leverage ratio"). The Base Rate was the highest of (i) the Prime Rate; (ii) the Federal Funds rate plus .50% per annum; and (iii) the Adjusted LIBO Rate determined on a daily basis for an Interest Period of one month plus 1.00% per annum, as such capitalized terms were defined in the Prior Credit Facility. The applicable

margin for a LIBOR-based borrowing ranged from .75% to 2.25%. The applicable margin for a Base Rate borrowing ranged from 0% to 1.25%. A fee was charged on the amount of the unused commitment ranging from .125% to .35% (depending on our leverage ratio). The Prior Credit Facility was unsecured and contained covenants that restricted the amount of certain payments, including dividends, and required, among other things, the maintenance of a total leverage ratio, a senior leverage ratio and a fixed charge coverage ratio. As of October 31, 2017, we were in compliance with all financial and nonfinancial covenants of the Prior Credit Facility. See Note 5, Long-Term Debt, of the Notes to Consolidated Financial Statements for further information regarding the Prior Credit Facility.

The following table summarizes our contractual obligations as of October 31, 2017

(in thousands):

__________________

consideration be paid for their equity interests (the "Redemption Amount"). As of October 31, 2017, management's estimate of the aggregate Redemption Amount of all Put Rights that we could be required to pay is approximately $131.1 million, which is reflected within redeemable noncontrolling interests in our Consolidated Balance Sheet. The amounts in the table do not include Put Right obligations as none of the noncontrolling interest holders have exercised their Put Rights as of October 31, 2017. See Note 11, Redeemable Noncontrolling Interests, of the Notes to Consolidated Financial Statements for further information.

Guarantees

As of October 31, 2017, we have arranged for standby letters of credit aggregating $4.2 million, which are supported by our revolving credit facility and pertain to payment guarantees related to potential workers' compensation claims and a facility lease as well as performance guarantees related to customer contracts entered into by certain of our subsidiaries.

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, "Revenue from Contracts with Customers," which provides a comprehensive new revenue recognition model that will supersede nearly all existing revenue recognition guidance. Under ASU 2014-09, an entity will recognize revenue when it transfers promised goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. ASU 2014-09, as amended, is effective for fiscal years and interim reporting periods within those years beginning after December 15, 2017, or in fiscal 2019 for HEICO. Early adoption in the year preceding the effective date is permitted. ASU 2014-09 shall be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application. We are currently evaluating which transition method we will elect. In addition, we are currently identifying our various revenue streams and reviewing certain underlying customer contracts to determine the effect the adoption of this guidance will have on our consolidated results of operations, financial position and cash flows.

In July 2015, the FASB issued ASU 2015-11, "Simplifying the Measurement of Inventory," which requires entities to measure inventories at the lower of cost or net realizable value. Under current guidance, inventories are measured at the lower of cost or market. ASU 2015-11 must be applied prospectively and is effective for fiscal years and interim reporting periods within those years beginning after December 15, 2016, or in fiscal 2018 for HEICO. We

are currently evaluating the effect, if any, the adoption of this guidance will have on our consolidated results of operations, financial position and cash flows.

In November 2015, the FASB issued ASU 2015-17, "Balance Sheet Classification of Deferred Taxes," which requires that all deferred tax assets and liabilities be classified as noncurrent in the balance sheet. We adopted ASU 2015-17 on a retrospective basis in the fourth quarter of fiscal 2017, resulting in a reclassification of $41.1 million in current deferred tax assets to noncurrent deferred tax liabilities in our Consolidated Balance Sheet as of October 31, 2016.

In February 2016, the FASB issued ASU 2016-02, "Leases," which requires recognition of lease assets and lease liabilities on the balance sheet of lessees. ASU 2016-02 is effective for fiscal years and interim reporting periods within those years beginning after December 15, 2018, or in fiscal 2020 for HEICO. Early adoption is permitted. ASU 2016-02 requires a modified retrospective transition approach and provides certain optional transition relief. We are currently evaluating the effect the adoption of this guidance will have on our consolidated results of operations, financial position and cash flows.

In March 2016, the FASB issued ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting," which simplifies several aspects related to accounting for share-based payment transactions. Under ASU 2016-09, all excess tax benefits and tax deficiencies are to be recognized in the statement of operations as a component of income tax expense rather than as capital in excess of par value. We adopted ASU 2016-09 in the first quarter of fiscal 2017 resulting in the recognition of a $3.1 million discrete income tax benefit, which, net of noncontrolling interests, increased net income attributable to HEICO by $2.6 million. Additionally, ASU 2016-09 requires excess tax benefits and deficiencies to be prospectively excluded from the assumed future proceeds in the calculation of diluted shares, which increased our weighted average number of diluted common shares outstanding by 781,000 for fiscal 2017. Further, ASU 2016-09 requires excess tax benefits be presented within the statement of cash flows as an operating activity rather than as a financing activity. We adopted this change on a prospective basis, which resulted in a $3.1 million increase in cash provided by operating activities and a $3.1 million decrease in cash provided by financing activities in fiscal 2017.

In August 2016, the FASB issued ASU 2016-15, "Classification of Certain Cash Receipts and Cash Payments," which clarifies how certain cash receipts and cash payments are to be presented and classified in the statement of cash flows. ASU 2016-15 provides guidance on eight specific cash flow classification issues including contingent consideration payments made after a business combination, proceeds from corporate-owned life insurance policies and distributions received from equity method investees. ASU 2016-15 is effective for fiscal years and interim reporting periods within those years beginning after December 15, 2017, or in fiscal 2019 for HEICO. Early adoption is permitted. ASU 2016-15 requires a retrospective transition approach for all periods presented. We are currently evaluating the effect the adoption of this guidance will have on its consolidated statement of cash flows.

In January 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment," which is intended to simplify the current test for goodwill impairment by eliminating the second step in which the implied value of a reporting unit is calculated when the carrying value of the reporting unit exceeds its fair value. Under ASU 2017-04, goodwill impairment should be recognized for the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 must be applied prospectively and is effective for any annual or interim goodwill impairment test in fiscal years beginning after December 15, 2019, or in fiscal 2021 for HEICO. Early adoption is permitted. We do not expect the adoption of this guidance to have a material impact on our consolidated results of operations, financial position and cash flows.

Certain statements in this report constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. All statements contained herein that are not clearly historical in nature may be forward-looking and the words "anticipate," "believe," "expect," "estimate" and similar expressions are generally intended to identify forward-looking statements. Any forward-looking statement contained herein, in press releases, written statements or other documents filed with the Securities and Exchange Commission or in communications and discussions with investors and analysts in the normal course of business through meetings, phone calls and conference calls, concerning our operations, economic performance and financial condition are subject to risks, uncertainties and contingencies. We have based these forward-looking statements on our current expectations and projections about future events. All forward-looking statements involve risks and uncertainties, many of which are beyond our control, which may cause actual results, performance or achievements to differ materially from anticipated results, performance or achievements. Also, forward-looking statements are based upon management's estimates of fair values and of future costs, using currently available information. Therefore, actual results may differ materially from those expressed in or implied by those forward-looking statements. Factors that could cause such differences include:

For further information on these and other factors that potentially could materially affect our financial results, see Item 1A, Risk Factors.   We undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except to the extent required by applicable law.

We have exposure to interest rate risk, mainly related to our revolving credit facility, which has variable interest rates.  Interest rate risk associated with our variable rate debt is the potential increase in interest expense from an increase in interest rates.  Based on our aggregate outstanding variable rate debt balance of $671.0 million as of October 31, 2017, a hypothetical 10% increase in interest rates would not have a material effect on our results of operations, financial position or cash flows. We also maintain a portion of our cash and cash equivalents in financial instruments with original maturities of three months or less.  These financial instruments are subject to interest rate risk and will decline in value if interest rates increase.  Due to the short duration of these financial instruments, a hypothetical 10% increase in interest rates as of October 31, 2017 would not have a material effect on our results of operations, financial position or cash flows.

We have a few foreign subsidiaries that conduct a portion of their operations in currencies other than the U.S. dollar, or principally in Euros, Canadian dollars and British pounds sterling. Accordingly, changes in exchange rates between such foreign currencies and the U.S. dollar will affect the translation of the financial results of our foreign subsidiaries into the U.S. dollar for purposes of reporting our consolidated financial results. A hypothetical 10% weakening in the exchange rate of the Euro, Canadian dollar or British pound sterling to the U.S. dollar as of October 31, 2017 would not have a material effect on our results of operations, financial position or cash flows.

To the Board of Directors and Shareholders of

HEICO Corporation

Hollywood, Florida

We have audited the accompanying consolidated balance sheets of HEICO Corporation and subsidiaries (the "Company") as of October 31, 2017 and 2016, and the related consolidated statements of operations, comprehensive income, shareholders' equity, and cash flows for each of the three years in the period ended October 31, 2017. Our audits also included the financial statement schedule listed in the Index at Item 15. These financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on the 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 HEICO Corporation and subsidiaries as of October 31, 2017 and 2016, and the results of their operations and their cash flows for each of the three years in the period ended October 31, 2017, 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 October 31, 2017, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated December 21, 2017 expressed an unqualified opinion on the Company's internal control over financial reporting.
