ITEM 1. BUSINESS
(Dollars in millions)

General

AAR CORP. and its subsidiaries are referred to herein collectively as "AAR," "Company," "we," "us," and "our" unless the context indicates otherwise. AAR was founded in 1951, organized in 1955 and reincorporated in Delaware in 1966. We are a diversified provider of products and services to the worldwide aviation and government and defense markets. We conduct our business activities primarily through six legal entities: AAR Parts Trading, Inc.; AAR Aircraft & Engine Sales & Leasing, Inc.; AAR Aircraft Services, Inc.; AAR Manufacturing, Inc.; AAR Airlift Group, Inc.; and AAR International, Inc.

We report our activities in two business segments: (i) Aviation Services, comprised primarily of business activities conducted through AAR Parts Trading, Inc.; AAR Aircraft & Engine Sales & Leasing, Inc.; AAR Aircraft Services, Inc.; AAR Allen Services, Inc. (a wholly-owned subsidiary of AAR Parts Trading, Inc.);. AAR Airlift Group, Inc. and AAR International, Inc.; and (ii) Technology Products, comprised primarily of business activities conducted through AAR Manufacturing, Inc. and AAR International, Inc.

Business Segments

Prior to the second quarter of fiscal year 2013, we reported our activities in four business segments: Aviation Supply Chain; Government and Defense Services; Maintenance, Repair and Overhaul; and Structures and Systems. During the second quarter, we changed our segment presentation to reflect the way our Chief Executive Officer evaluates performance and the way we are organized internally. We now report our activities in two business segments: Aviation Services and Technology Products. The Aviation Services segment includes our former Aviation Supply Chain and Maintenance, Repair and Overhaul segments and most of the former Government and Defense Services segment, and the new Technology Products segment represents our former Structures and Systems business segment and our small shelter integration unit, which previously was part of the Government and Defense Services segment. We have recast all prior periods presented to conform to the new segment presentation.

Aviation Services

The Aviation Services segment provides aftermarket support and services for the commercial aviation and government and defense markets. In this segment, we provide inventory management and distribution services, overhaul, repair and engineering services, and expeditionary airlift services.

We sell and lease a wide variety of new, overhauled and repaired engine and airframe parts and components to our commercial and defense customers. We are also an authorized distributor for more than 80 leading aviation product manufacturers.

We provide customized inventory supply and management, warranty claim management, and outsourcing programs for engine and airframe parts and components in support of our airline customers' maintenance activities. The types of services provided under these programs include material planning, sourcing, logistics, information and program management, and parts and component repair and overhaul.

We also provide customized performance-based logistics programs in support of the U.S. Department of Defense and foreign governments. The types of services provided under these programs include material planning, sourcing, logistics, information and program management, airframe maintenance and maintenance planning, and component repair and overhaul.

We provide major airframe maintenance inspection and overhaul, painting services, line maintenance, airframe modifications, structural repairs, avionic service and installation, exterior and interior

Table of Contents

refurbishment, and engineering services and support for many types of commercial and military aircraft. We also repair and overhaul landing gears, wheels, and brakes for commercial and military aircraft.

We operate five airframe maintenance facilities and one landing gear overhaul facility. Our airframe maintenance facilities are in Indianapolis, Indiana; Oklahoma City, Oklahoma; Duluth, Minnesota; and Miami, Florida and a regional aircraft maintenance facility in Hot Springs, Arkansas. Our landing gear overhaul facility is in Miami, Florida, where we repair and overhaul landing gear, wheels, brakes, and actuators for different types of commercial and military aircraft.

We provide expeditionary airlift services to the United States and other government customers. Our airlift services provide fixed- and rotary-wing flight operations, transporting personnel and cargo principally in support of the U.S. Department of Defense. We operate a fleet of customized fixed- and rotary-wing aircraft, principally in Afghanistan, Northern Africa and Western Pacific regions. We hold FAR Part 133 and 135 certificates to operate aircraft and a FAR Part 145 certificate to operate a repair station. We are also Commercial Aircraft Review Board certified with the U.S. Department of Defense.

Activities in our Aviation Services segment also include the sale and lease of used commercial aircraft. Each sale or lease is negotiated as a separate agreement which includes term, price, representations, warranties, and lease return provisions. Since 2008, our strategy has been to gradually reduce our investment in our joint venture and wholly-owned aircraft portfolios available for lease or sale to the commercial airline market. At May 31, 2013, we held four aircraft in joint ventures and two wholly-owned aircraft.

The majority of our sales are made pursuant to standard commercial purchase orders. Certain inventory supply and management and performance-based logistics program agreements reflect negotiated terms and conditions.

To support activities within the Aviation Services segment, we acquire aviation parts and components from domestic and foreign airlines, independent aviation service companies, aircraft leasing companies, and Original Equipment Manufacturers ("OEM"s). We have ongoing arrangements with OEMs that provide us access to parts, repair manuals, and service bulletins in support of parts manufactured by them. Although the terms of each arrangement vary, they typically are made on standard OEM terms as to duration, price, and delivery. From time to time, we purchase aircraft and engines for disassembly into individual parts and components. These assets may be leased to airlines on a short-term basis prior to disassembly.

Technology Products

Activities in our Technology Products segment include the design, manufacture, and repair of airdrop and other transportation pallets, and a wide variety of containers and shelters used in support of military and humanitarian tactical deployment activities. The containers and shelters are used in numerous mission requirements, including armories, supply and parts storage, refrigeration systems, tactical operation centers, briefing rooms, laundry and kitchen facilities, water treatment, and sleeping quarters. We also design and manufacture transportation pallets and a wide variety of containers used in commercial airlines.

In this segment, we also design, manufacture, and install in-plane cargo loading and handling systems for commercial aircraft, military aircraft, and helicopters. We are a provider of complex machined and fabricated parts, components, and sub-systems for various aerospace and defense programs and other applications. We design and manufacture advanced composite materials for commercial, business, and military aircraft. We provide engineering, design, and system integration services for specialized command and control systems. Sales in this segment are made to customers pursuant to standard commercial purchase orders and contracts. We purchase raw materials for this business, including steel, titanium, aluminum, extrusions and castings, and other necessary supplies, from several vendors.

Table of Contents

Raw Materials

We have been able to obtain raw materials and other inventory items from numerous sources for each segment at competitive prices, terms, and conditions; we expect to be able to continue to do so.

Terms of Sale

We generally sell our products under standard 30-day payment terms. On occasion, certain customers, principally foreign customers, will negotiate extended payment terms of 60-90 days. Except for customary warranty provisions, customers neither have the right to return products nor do they have the right to extended financing. Our contracts with the U.S. Department of Defense and its contractors, the U.S. Department of State, and other governmental agencies are typically firm agreements to provide products and services at a fixed price or on a time and material basis, and have a term of one year or less, frequently subject to extension for one or more additional periods of one year at the option of the government customer.

Customers

We primarily market and sell products and services through our own employees. In certain markets outside of the United States, we rely on foreign sales agents to assist in the sale of our products and services.

The principal customers for our products and services in the Aviation Services segment are domestic and foreign commercial airlines, domestic and foreign freight airlines, regional and commuter airlines, business and general aviation operators, OEMs, aircraft leasing companies, aftermarket aviation support companies, the U.S. Department of Defense and its contractors, the U.S. Department of State, and foreign military organizations or governments. In the Technology Products segment, our principal customers include the U.S. Department of Defense and its contractors, foreign governmental and defense organizations, domestic and foreign commercial airlines, domestic and foreign freight airlines, OEMs, large system providers, and other industrial entities.

Sales of aviation products and services to our commercial airline customers are generally affected by such factors as the number, type and average age of aircraft in service, the levels of aircraft utilization (e.g., frequency of schedules), the number of airline operators, the general economy, and the level of sales of new and used aircraft. Sales to the U.S. Department of Defense, U.S. Department of State, and other government agencies are subject to a number of factors, including the level of troop deployment worldwide, government funding, competitive bidding, and requirements generated by worldwide geopolitical events.

Licenses

We have 13 Federal Aviation Administration ("FAA") licensed repair stations in the United States and Europe. Of the 13 licensed FAA repair stations, six are also European Aviation Safety Agency ("EASA") licensed repair stations. Such licenses, which are ongoing in duration, are required in order for us to perform authorized maintenance, repair and overhaul services for our customers and are subject to revocation by the government for non-compliance with applicable regulations. Of the 13 FAA licensed repair stations, 12 are in the Aviation Services segment and one is in the Technology Products segment. The six EASA licensed repair stations are in the Aviation Services segment. We also hold FAR Part 133 and 135 certificates to operate aircraft in our Aviation Services segment. We are also Commercial Aircraft Review Board certified with the U.S. Department of Defense. We believe that we possess all licenses and certifications that are material to the conduct of our business.

Table of Contents

Competition

Competition in each of our markets is based on quality, ability to provide a broad range of products and services, speed of delivery, and price. Competitors in our Aviation Services segment include OEMs, the service divisions of large commercial airlines, and other independent suppliers of parts, repair, and overhaul services to the commercial and defense markets. Our expeditionary airlift services unit competes with domestic and foreign contracting companies. Our manufacturing, machining and engineering activities in our Technology Products segment compete with a number of divisions of large corporations and other large and small companies. Although certain of our competitors have substantially greater financial and other resources than we do, we believe that we have maintained a satisfactory competitive position through our responsiveness to customer needs, our attention to quality, and our unique combination of market expertise and technical and financial capabilities.

Backlog

At May 31, 2013, backlog believed to be firm was approximately $973.0 million compared to $928.7 million at May 31, 2012. Approximately $739.1 million of our May 31, 2013 backlog is expected to be filled within the next 12 months.

Employees

At May 31, 2013, we employed approximately 6,300 employees worldwide, of which approximately 230 employees are subject to a collective bargaining agreement. We also retain approximately 900 contract workers, the majority of whom are located at our airframe maintenance facilities.

Sales to Government and Defense Customers

Sales to global government and defense customers were $839.2 million (39.3% of total sales), $930.4 million (45.1% of total sales) and $948.3 million (52.5% of total sales) in fiscal years 2013, 2012 and 2011, respectively. Sales to branches, agencies, and departments of the U.S. government and their contractors were $763.2 million (35.7% of total sales), $888.5 million (43.0% of total sales), and $893.1 million (49.5% of total sales) in fiscal years 2013, 2012, and 2011, respectively. Sales to government and defense customers are reported in each of our reportable segments (See Note 16 of Notes to Consolidated Financial Statements). Since such sales are subject to competitive bidding and government funding, no assurance can be given that such sales will continue at levels previously experienced. The majority of our U.S. government contracts is for products and services supporting the U.S. Department of Defense logistics and mobility strategy, as well as for supplemental airlift services. Thus, our government contracts may change with fluctuations in defense and other governmental agency spending. Our government contracts are also subject to termination by the customer; in the event of such a termination we would be entitled to recover all allowable costs incurred by us through the date of termination.

ITEM 1A. RISK FACTORS

The following is a description of the principal risks inherent in our business.

We are affected by factors that adversely impact the commercial aviation industry.

As a provider of products and services to the commercial aviation industry, we are greatly affected by overall economic conditions of that industry. The commercial aviation industry is historically cyclical and has been negatively affected in the past by geopolitical events, high oil prices, lack of capital, and weak economic conditions. In addition, as a result of these and other events, from time-to-time certain of our customers have filed for bankruptcy protection or ceased operation.

In calendar year 2008 and into 2009, demand for air transportation in the United States and abroad declined due to economic deterioration in the U.S. and other global economies. Although global economic conditions improved in the 2010 to 2013 period, the recovery has generally been sluggish in the U.S. and in many other developed nations. The impact of persistently high fuel costs and the continued sluggish or weak worldwide economic conditions may lead airlines to reduce domestic or international capacity. In addition, certain of our airline customers have in the past been impacted by tight credit markets, which limited their ability to buy parts, services, engines, and aircraft.

A reduction in the operating fleet of aircraft both in the U.S. and abroad will result in reduced demand for parts support and maintenance activities for the type of aircraft affected. Further, tight credit conditions negatively impact the amount of liquidity available to buy parts, services, engines, and aircraft. A deteriorating airline environment may also result in additional airline bankruptcies, and we may not be able to fully collect outstanding accounts receivable. Reduced demand from customers caused by weak economic conditions, including tight credit conditions and customer bankruptcies, may adversely impact our financial condition or results of operations.

Our business, financial condition, results of operations, and growth rates may be adversely affected by these and other events that impact the aviation industry, including the following:

•: deterioration in the financial condition of our existing and potential customers;
•: reductions in the need for, or the deferral of, aircraft maintenance and repair services and spare parts support;
•: retirement of older generation aircraft, resulting in lower prices for spare parts and services for those aircraft;
•: reductions in demand for used aircraft and engines;
•: increased in-house maintenance by airlines;
•: high oil prices;
•: lack of parts in the marketplace;
•: future terrorist attacks and the ongoing war on terrorism;
•: future outbreaks of infectious diseases; and
•: acts of God.

Our U.S. government contracts may not continue at present sales levels, which may have a material adverse effect on our financial condition and results of operations.

Our sales to branches, agencies and departments of the U.S. government and their contractors were $763.2 million (35.7% of consolidated sales) in fiscal year 2013 (See Note 16 of Notes to Consolidated Financial Statements). The majority of our U.S. government contracts is for products and services

Table of Contents

supporting U.S. Department of Defense logistics and mobility strategy, as well as for supplemental airlift services and are, therefore, subject to changes in defense and other governmental agency funding and spending. Our contracts with the U.S. government, including the Department of Defense and its contractors, are typically agreements to provide products and services at a fixed price and have a term of one year or less, frequently subject to extension for one or more additional periods of one year at the option of the government customer. Sales to agencies of the U.S. government and their contractors are subject to a number of factors, including the level of troop deployment worldwide, competitive bidding, U.S. government funding, requirements generated by world events, and budgetary constraints.

Defense funding is currently facing pressure due to U.S. budget deficit challenges. Congress enacted the Budget Control Act of 2011 ("Budget Act"), which reduced defense spending by a minimum of $487 billion over a ten-year period that began in government fiscal year 2012. Considering the Budget Act and deficit reduction pressures, it is likely that discretionary spending by the federal government will remain constrained for several years.

The American Taxpayer Relief Act of 2012 ("Taxpayer Relief Act") delayed the pending sequestration of appropriations imposed by the Budget Act by two months, from January 2, 2013 to March 1, 2013, and reduced the amount of the government fiscal year 2013 budget cuts. Sequestration went into effect March 1, 2013. On March 26, 2013, the President signed into law the Consolidated Further Continuing Appropriations Act, which includes specific appropriations for the U.S. Department of Defense. On April 10, 2013, the President delivered his proposed fiscal 2014 budget to Congress. The President's $527 billion fiscal 2014 defense budget is lower than the final defense appropriations for fiscal 2013.

While the specific effects of sequestration still cannot be determined, the automatic across-the-board cuts would approximately double the amount of the ten-year $487 billion reduction in the U.S. government defense spending that began in government fiscal year 2012 already required by the Budget Act. At this time, we have no information from our defense customers or otherwise that would allow us to estimate the impact of sequestration on our defense sales; however, our government-related business could be adversely impacted if no legislative or other solution is reached in the near future and sequestration remains in effect for an extended period.

Acquisitions expose us to risks, including the risk that we may be unable to effectively integrate acquired businesses.

We continue to grow through acquisitions. We explore and have discussions with third parties regarding additional acquisitions on a regular basis. Acquisitions involve risks, including difficulties in integrating the operations and personnel, the effects of amortization of any acquired intangible assets and the potential impairment of goodwill, and the potential loss of key employees of the acquired business. For our recent acquisitions, and for any businesses we may acquire in the future, we may not be able to execute our operational, financial, or integration plans for the acquired businesses, which could adversely affect our results of operations and financial condition.

We face risks of cost overruns and losses on fixed-price contracts.

We sell certain of our products and services to our commercial, government, and defense customers under firm contracts providing for fixed unit prices, regardless of costs incurred by us. The cost of producing products or providing services may be adversely affected by increases in the cost of labor, materials, fuel, overhead, and other unknown variants, including manufacturing and other operational inefficiencies and differences between assumptions used by us to price a contract and actual results. Increased costs may result in cost overruns and losses on such contracts, which could adversely affect our results of operations and financial condition.

Table of Contents

Significant cost issues may develop in connection with the A400M cargo system.

Our Cargo Systems unit was selected in June 2005 to provide cargo loading systems for the Airbus A400M Military Transport Aircraft ("A400M"). We have incurred significant engineering and development costs in connection with this program (see Note 15 in Notes to Consolidated Financial Statements), and we expect to incur additional costs until final design approval, which is currently scheduled for the first calendar quarter of 2014. In July 2013, we and Airbus amended the A400M contract to make changes to the Company's role and responsibilities under the program, establish a fixed price per shipset, set applicable weight parameters and make certain other changes. The Company believes that the revised fixed pricing schedule will enable the Company to recover its engineering and development costs, provided the Company achieves specified reductions in the production costs of those items over which it has continuing responsibility.

We may not be able to recover our engineering and development costs, which could adversely affect our operating results and financial condition, under certain circumstances, including the following: (i) the A400M program experiences significant additional delivery delays or order cancellations; (ii) we fail to achieve the expected production cost reductions; (iii) we fail to deliver the items that we are now responsible for in accordance with the terms of the amended contract; or (iv) the contract is further amended to change our role and responsibilities.

Success at our airframe maintenance facilities is dependent upon continued outsourcing by the airlines.

We currently perform airframe maintenance, repair and overhaul activities at leased facilities in Indianapolis, Indiana; Oklahoma City, Oklahoma; Miami, Florida; Duluth, Minnesota; and Hot Springs, Arkansas. Revenues at these facilities fluctuate based on demand for maintenance which, in turn, is driven by the number of aircraft operating and the extent of outsourcing of maintenance activities by airlines. If either the number of aircraft operating or the level of outsourcing of maintenance activities declines, we may not be able to execute our operational and financial plans at our maintenance, repair and overhaul facilities, which could adversely affect our results of operations and financial condition.

We operate in highly competitive markets, and competitive pressures may adversely affect us.

The markets for our products and services to our commercial, government, and defense customers are highly competitive, and we face competition from a number of sources, both domestic and international. Our competitors include aircraft manufacturers, aircraft component and parts manufacturers, airline and aircraft service companies, other companies providing maintenance, repair and overhaul services, other aircraft spare parts distributors and redistributors, and other expeditionary airlift service providers. Some of our competitors have substantially greater financial and other resources than we have and others may price their products and services below our selling prices. These competitive pressures could adversely affect our results of operations and financial condition.

We are subject to significant government regulation and may need to incur significant expenses to comply with new or more stringent governmental regulation.

The aviation industry is highly regulated by the FAA in the United States and equivalent regulatory agencies in other countries. Before we sell any of our products that are to be installed in an aircraft, such as engines, engine parts and components, and airframe and accessory parts and components, they must meet certain standards of airworthiness established by the FAA or the equivalent regulatory agencies in certain other countries. We operate repair stations that are licensed by the FAA and the equivalent regulatory agencies in certain other countries, and hold certificates to operate aircraft. Specific regulations vary from country to country, although regulatory requirements in other countries are generally satisfied by compliance with FAA requirements. New and more stringent governmental regulations may be adopted in the future that, if enacted, may have an adverse impact on us.

Table of Contents

If any of our material licenses, certificates, authorizations, or approvals were revoked or suspended by the FAA or equivalent regulatory agencies in other countries, our results of operations and financial condition may be adversely affected.

If we fail to comply with complex procurement laws and regulations, we could lose business and be liable for various penalties or sanctions.

We must comply with laws and regulations relating to the formation, administration, and performance of U.S. government contracts. These laws and regulations include the Federal Acquisition Regulations, Defense Federal Acquisition Regulations, the Truth in Negotiations Act, Cost Accounting Standards, and laws, regulations, and orders restricting the use and dissemination of classified information under the U.S. export control laws and the export of certain products and technical information. In complying with these laws and regulations, we may incur significant costs, and non-compliance may result in the imposition of fines and penalties, including contractual damages. If we fail to comply with these laws and regulations or if a government audit, review, or investigation uncovers improper or illegal activities, we may be subject to civil penalties, criminal penalties, or administrative sanctions, including debarment from contracting with the U.S. Government. Our reputation could suffer harm if allegations of impropriety were made against us, which could adversely affect our operating performance and may result in additional expenses and possible loss of revenue.

The majority of Airlift's revenue is derived from providing expeditionary airlift services in Afghanistan.

Airlift derives most of its revenue from providing supplemental airlift services in Afghanistan for the U.S. Department of Defense. The U.S. has announced plans to reduce substantially military activities in Afghanistan in 2014 and withdraw the majority of its troops, although the timing and number of troops to be withdrawn is not precisely known. Airlift has contracts with option renewals in October 2013 and May 2014 with an aggregate annual sales value of approximately $220 million. In addition, Airlift has a contract expiring on November 30, 2013 with an annual sales value of $110 million. Although we expect significant ongoing demand for airlift services in Afghanistan from the U.S. Department of Defense and other governmental departments, we are exposed to the risk that our revenues at Airlift may decline if these contracts are not renewed, renewed only in part, or are terminated, which could adversely affect our results of operations and financial condition. Airlift's inability to diversify its customer base beyond the U.S. Department of Defense in Afghanistan could adversely affect our results of operations and financial condition.

U.S. government contractors that provide support services in theaters of conflict such as Afghanistan have come under increasing scrutiny by agency inspectors general government auditors and congressional committees. Investigations pursued by any or all of these groups may result in adverse publicity for us and reputational harm, regardless of the underlying merit of the allegations being investigated.

We are exposed to risks associated with operating internationally.

We conduct our business in certain foreign countries, some of which are politically unstable or subject to military or civil conflicts. Consequently, we are subject to a variety of risks that are specific to international operations, including the following:

•: military conflicts, civil strife, and political risks;
•: export regulations that could erode profit margins or restrict exports;
•: compliance with the U.S. Foreign Corrupt Practices Act and other anti-bribery laws;
•: the burden and cost of compliance with foreign laws, treaties, and technical standards and changes in those regulations;

Table of Contents

•: contract award and funding delays;
•: potential restrictions on transfers of funds;
•: import and export duties and value added taxes;
•: foreign exchange risk;
•: transportation delays and interruptions; and
•: uncertainties arising from foreign local business practices and cultural considerations.

While we have and will continue to adopt measures to reduce the potential impact of losses resulting from the risks of doing business internationally, we cannot ensure that such measures will be adequate or that the regions in which we operate will continue to be stable enough to allow us to operate profitably or at all.

Market values for our aviation products fluctuate, and we may be unable to re-lease or sell aircraft and engines when their current lease expires.

We use a number of assumptions when determining the recoverability of inventories, aircraft, and engines, which are on lease or available for lease. These assumptions include historical sales trends, current and expected usage trends, replacement values, current and expected lease rates, residual values, future demand, and future cash flows. Reductions in demand for our inventories or declining market values, as well as differences between actual results and the assumptions utilized by us when determining the recoverability of our inventories, aircraft, and engines, could result in impairment charges in future periods.

We lease aircraft and engines to our customers on an operating lease basis. Our ability to re-lease or sell these assets on acceptable terms when the lease expires is subject to a number of factors which drive industry capacity, including new aircraft deliveries, availability of used aircraft and engines in the marketplace, competition, financial condition of our customers, overall health of the airline industry, and general economic conditions. Our inability to re-lease or sell aircraft and engines could adversely affect our results of operations and financial condition.

We are dependent upon continued availability of financing to manage our business and to execute our business strategy, and additional financing may not be available on terms acceptable to us.

Our ability to manage our business and to execute our business strategy is dependent, in part, on the continued availability of debt and equity capital. Access to the debt and equity capital markets may be limited by various factors, including the condition of overall credit markets, general economic factors, state of the aviation industry, our financial performance, and credit ratings. Debt and equity capital may not continue to be available to us on favorable terms, or at all. Our inability to obtain financing on favorable terms could adversely affect our results of operations and financial condition.

Our existing debt includes restrictive and financial covenants.

Certain loan and debt agreements require us to comply with various restrictive covenants and some contain financial covenants that require us to comply with specified financial ratios and tests. Our failure to meet these covenants could result in default under these loan and debt agreements and may result in a cross-default under other debt agreements. In the event of a default and our inability to obtain a waiver of the default, all amounts outstanding under our debt agreements could be declared immediately due and payable. Our failure to comply with these covenants could adversely affect our results of operations and financial condition.

Our industry is susceptible to product and other liability claims, and claims not adequately covered by insurance may adversely affect our financial condition.

Our business exposes us to possible claims for property damage and bodily injury or death which may result if an engine, engine part or component, airframe part or accessory, or any other aviation product which we have sold, manufactured, or repaired fails, or if an aircraft we operated, serviced, or in which our products are installed crashes and the cause cannot be determined. We carry substantial liability insurance in amounts that we believe are adequate for our risk exposure and commensurate with industry norms. However, claims may arise in the future, and our insurance coverage may not be adequate to protect us in all circumstances. Additionally, we might not be able to maintain adequate insurance coverage in the future at an acceptable cost. Any liability claim not covered by adequate insurance could adversely affect our results of operations and financial condition.

Our business could be negatively affected by cyber or other security threats or other disruptions.

We face cyber threats, threats to the physical security of our facilities and employees, and terrorist acts, as well as the potential for business disruptions associated with information technology failures, natural disasters, or public health crises. These threats arise in some cases as a result of our role as a defense contractor.

Cyber security threats are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to our sensitive information, including our customers, suppliers, subcontractors, and joint venture partners, and other electronic security breaches that could lead to disruptions in mission critical systems, unauthorized release of confidential or otherwise protected information, and corruption of data.

Although we utilize various procedures and controls to monitor and mitigate these threats, there can be no assurance that these procedures and controls will be sufficient to prevent security threats from materializing. If any of these events were to materialize, the costs related to cyber or other security threats or disruptions may not be fully insured or indemnified and could have a material adverse effect on our reputation, operating results, and financial condition.

We must comply with extensive environmental requirements, and any exposure to environmental liabilities may adversely affect us.

Federal, state, and local requirements relating to the discharge and emission of substances into the environment, the disposal of hazardous wastes, the remediation and abatement of contaminants, and other activities affecting the environment have had and may continue to have an impact on our operations. Management cannot assess the possible effect of compliance with future environmental requirements or of future environmental claims for which we may not have adequate indemnification or insurance coverage. If we were required to pay the expenses related to any future environmental claims for which neither indemnification nor insurance coverage were available, these expenses could have an adverse impact on our results of operations and financial condition.

Future environmental regulatory developments in the United States and abroad concerning environmental issues, such as climate change, could adversely affect our operations and increase operating costs and, through their impact on our customers, reduce demand for our products and services. Actions may be taken in the future by the U.S. government, state governments within the United States, foreign governments, the International Civil Aviation Organization, or by signatory countries through a new global climate change treaty to regulate the emission of greenhouse gases by the aviation industry. The precise nature of any such requirements and their applicability to us and our customers are difficult to predict, but the impact to us and the aviation industry would likely be adverse and could be significant, including the potential for increased fuel costs, carbon taxes or fees, or a requirement to purchase carbon credits.

We may need to make significant capital expenditures to keep pace with technological developments in our industry.

The industries in which we participate are constantly undergoing development and change, and it is likely that new products, equipment, and methods of repair and overhaul services will be introduced in the future. We may need to make significant expenditures to purchase new equipment and to train our employees to keep pace with any new technological developments. These expenditures could adversely affect our results of operations and financial condition.

Our operations would be adversely affected by a shortage of skilled personnel or work stoppages.

We are dependent on an educated and highly skilled workforce, because of the complex nature of many of our products and services. Furthermore, we have a collective bargaining agreement covering approximately 230 employees. Our ability to operate successfully and meet our customers' demands could be jeopardized if we are unable to attract and retain a sufficient number of skilled personnel, including qualified licensed mechanics, to conduct our business, or if we experience a significant or prolonged work stoppage. These and similar events may adversely affect our results of operations and financial condition.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
(Dollars in millions)

Forward-Looking Statements

Management's Discussion and Analysis of Financial Condition and Results of Operations contain certain statements relating to future results, which are forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on the beliefs of management, as well as assumptions and estimates based on information available to us as of the dates such assumptions and estimates are made, and are subject to certain risks and uncertainties that could cause actual results to differ materially from historical results or those anticipated, depending on a variety of factors, including those factors discussed under Item 1A, "Risk Factors." Should one or more of those risks or uncertainties materialize adversely, or should underlying assumptions or estimates prove incorrect, actual results may vary materially from those described. Those events and uncertainties are difficult or impossible to predict accurately and many are beyond our control. We assume no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events.

General Overview

We report our activities in two business segments: Aviation Services and Technology Products.

The Aviation Services segment provides aftermarket support and services and includes the sale and lease of a wide variety of new, overhauled and repaired engine and airframe parts and components to the commercial aviation and government and defense markets. We provide customized inventory supply chain management, performance based logistics programs, aircraft component repair management services, and aircraft modifications. The segment also includes repair, maintenance and overhaul of aircraft and landing gear and expeditionary airlift services. Cost of sales consists principally of the cost of product, direct labor, overhead, and aircraft maintenance costs.

Sales in the Technology Products segment are derived from the engineering, designing, manufacturing and supporting a broad range of products, including in-plane cargo loading and handling systems for commercial and military applications; containers, pallets and shelters used to support the U.S. military's requirements for a mobile and agile force and system integration services for specialized command and control systems. The segment also manufactures heavy-duty pallets and lightweight cargo containers for the commercial market, and steel and composite machined and fabricated parts, components and sub-systems for various aerospace and defense programs. Cost of sales consists principally of the cost of material to manufacture products, direct labor and overhead.

Our chief operating decision making officer (Chief Executive Officer) evaluates performance based on the reportable segments and utilizes gross profit as a primary profitability measure. The assets and certain expenses related to corporate activities are not allocated to the segments. Our reportable segments are aligned principally around differences in products and services. The tables below set forth consolidated sales and gross profit for our two business segments for each of the last three fiscal years ended May 31:

Business Trends and Highlights

During fiscal 2013, sales to commercial customers increased 14.4% compared to the prior year and represented 61% of consolidated sales. Commercial sales growth during fiscal 2013 was driven by strong organic growth in the Aviation Services segment and by the Telair International GmbH ("Telair") and Nordisk Aviation Products, AS ("Nordisk") acquisitions, completed in the third quarter of fiscal 2012.

We expect continued solid demand for our products and services to the commercial market as a result of the trend toward outsourced maintenance and comprehensive supply chain solutions, as well as commercial growth outside of North America.

During fiscal 2013, sales to global government and defense customers decreased 9.8% compared to the prior year and represented 39% of consolidated sales. Overall sales to government and defense customers declined due to lower volumes at our mobility products unit and lower logistics program activity, partially offset by increased sales at our expeditionary airlift unit.

U.S. defense funding is currently facing pressure due to budget deficit challenges and sequestration, which went into effect March 1, 2013. During the fourth quarter of fiscal 2013, we recorded a $29.8 million charge to lower profit expectations on a contract supporting the KC10 aircraft, primarily as a result of lower than expected flight hours of the KC10 aircraft. The full effects of sequestration on our business cannot be determined and we have no information from our defense customers or otherwise that would allow us to further estimate the impact of sequestration on future defense sales; however, our government-related business could be adversely impacted if no legislative or other solution is reached in the near future and sequestration remains in effect for an extended period.

Outlook for Fiscal 2014

We expect fiscal 2014 consolidated sales of approximately $2,175 million to $2,225 million. We expect to see continued strength in our supply chain and repair businesses in fiscal 2014, given its strong position to capture additional share of the growing global outsourced maintenance supply chain market. While defense budgets are expected to remain under pressure, we are seeing strong global demand across commercial and government entities for contractor operated airlift services, in which we are a recognized leader. Finally, we expect our Technology Products segment will see revenue stability in fiscal 2014, while focusing on cost base efficiencies and innovations in lightweight solutions for the marketplace. We believe we will continue to see improvement in our operating margins both as a result of mix improvement and a variety of projects to enhance efficiency and expect to report full year diluted earnings per share in the range of $2.00 to $2.05.

Results of Operations

Fiscal 2013 Compared with Fiscal 2012

Consolidated sales for fiscal 2013 increased $72.3 million or 3.5% compared to the prior year.

In the Aviation Services segment, sales increased $78.4 million or 5.1% over the prior year. The sales increase was driven by a number of factors, including increased program activity in our commercial parts support unit as a result of a component support contract executed in the fourth quarter of fiscal 2012;

Table of Contents

growth at our airframe maintenance centers reflecting new contract wins and expanded relationships with existing customers; and the favorable impact on sales of fleet utilization improvement at our expeditionary airlift unit. The sales increases were offset by lower sales in our defense logistics unit due to the fourth quarter adjustment to the KC10 support contract. During the fourth quarter of 2013, we recorded a $29.8 million pre-tax charge due to reduced sales and profit expectations on the contract as a result of lower expected flight hours of the KC10 aircraft, as well as changes to our anticipated recovery of costs in excess of amounts billed within this contract. In addition, in the prior year we sold four wholly-owned aircraft which contributed to approximately $49.0 million in aircraft sales. There were no wholly-owned aircraft sales during the current fiscal year from our aircraft leasing portfolio.

Gross profit in the Aviation Services segment decreased $9.8 million or 4.1%, and the gross profit margin percentage decreased to 14.1% from 15.4% in the prior year. The decrease in gross profit and gross profit margin percentage was primarily driven by the $29.8 million pre-tax charge on the KC10 support contract. Partially offsetting this decrease was an increase to gross profit margin at our expeditionary airlift unit due to the improved rate of availability of our fully mission critical fixed- and rotary-wing aircraft and increased flight hours. In addition, our high margin engineering service unit contributed to a strong gross profit due to the addition of a new program during fiscal 2013.

In the Technology Products segment, sales decreased $6.1 million or 1.2% over the prior year due to completion of a large contract and lower demand for shelters and containers due to the drawdown of the war effort in Afghanistan, and lower demand on certain other programs as the U.S. Department of Defense reduced its spending for these types of products we produce. These sales were partially offset by the impact of the full year inclusion of revenue at Telair and Nordisk.

Gross profit in the Technology Products segment increased $5.4 million or 6.6%, and the gross profit margin percentage increased to 16.6% from 15.4% in the prior year. The increase in gross profit margin percentage was primarily due to improved product mix resulting from the acquisitions. The increase was partially offset by a decline in gross profit in our mobility unit due to lower sales.

Selling, general and administrative expenses increased $9.0 million or 4.8% due to the full year inclusion of the fiscal year 2012 acquired companies, partially offset by the final settlement on the Airinmar Holdings Limited ("Airinmar") earn-out payment (See Note 8 of Notes to Consolidated Financial Statements). Earnings from aircraft joint ventures increased $5.3 million primarily due to the sale of ten aircraft from our aircraft joint venture portfolio and higher lease revenue in fiscal 2013.

Operating income decreased $8.1 million or 6.2% primarily due to the KC10 contract adjustment, partially offset by the increase in sales. Net interest expense increased $3.6 million or 9.9% compared to the prior year primarily due to the increase in borrowings incurred in the second half of fiscal 2012 to fund the fiscal 2012 acquisitions.

Our effective income tax rate for fiscal 2013 was 32.5%, which included a $1.3 million reduction in income tax expense related to the reduction of our state income tax rate from continued implementation of state tax planning strategies. In the prior year our effective income tax rate was 27.2%, which included a $3.3 million reduction in income tax expense primarily relating to revisions in book versus tax differences, and a $4.0 million reduction in income tax expense, primarily related to the reduction in our state income tax rate from the implementation of state tax planning strategies. Our state tax planning strategies included a new corporate structure and the relocation of one of our significant business units.

Net income was $55.0 million compared to $67.7 million in the prior year due to the factors discussed above.

Fiscal 2012 Compared with Fiscal 2011

Consolidated sales for fiscal 2012 increased $259.9 million or 14.4% compared to the prior year period. Sales to commercial customers increased 32.4% compared to the prior year and included strong

Table of Contents

organic growth in our Aviation Services segment, as well as sales from the newly acquired units in the Technology Products segment. Sales to government and defense customers decreased 1.9% principally due to lower sales at our defense logistics unit.

In the Aviation Services segment, sales increased $137.8 million or 9.9% over the prior year. The sales increase was driven by a number of factors, including strength at our parts supply unit, which benefited from the improved commercial airline environment and investments of assets, the sale of four aircraft for approximately $49.0 million from our aircraft sales and leasing portfolio, the addition of Airinmar, which contributed sales of $26.1 million, and continued growth and share gains at our heavy maintenance facilities. The sales increases were partially offset by weaker part sales in our defense logistics unit due to lower program activity driven by decreased flight hours, lower sales at our engineering services unit, and the fourth quarter fiscal 2012 adjustment to the KC10 support contract. During the fourth quarter of 2012, we recorded a $9.5 million pre-tax charge as a result of lowering our profit expectations on the KC10 support contract. This adjustment represents the difference between the new margin expectation and the previous margin expectation for the period of performance since contract inception in February 2010.

Gross profit in the Aviation Services segment increased $1.8 million, and the gross profit margin percentage decreased to 15.4% from 16.8% in the prior year. The decrease in gross profit margin was due to decreased Airlift margins as a result of unfavorable aircraft availability in the last half of fiscal 2012, the impact of the KC10 support contract adjustment reflecting a lower profit margin expectation, and lower sales in fiscal 2012 of the high margin engineering services.

In the Technology Products segment, sales increased $122.1 million or 30.0% over the prior year due to the inclusion of Telair and Nordisk, which contributed $119.4 million of revenue during fiscal 2012. Gross profit in the Technology Products segment increased $9.7 million or 13.5%; however the gross profit margin percentage decreased to 15.4% from 17.6% in the prior year. Factors impacting the decline in margin percentage include the mix of products sold, losses on certain programs and start-up costs on new programs at our precision machining unit, and the restructuring and impairment charges taken in the fourth quarter of fiscal 2012 of $3.7 million (see Note 12 of Notes to Consolidated Financial Statements).

During the fourth quarter of fiscal 2011, we sold the assets of a non-strategic product line within our Aviation Services segment. Proceeds from the sale of the product line were $10.0 million cash, and the net carrying value of the assets sold was $4.1 million. The gain on this transaction has been classified as a component of operating income.

Selling, general and administrative expenses increased $6.7 million or 3.7% due to the inclusion of selling, general and administrative expenses for the three acquired companies. Earnings from aircraft joint ventures decreased $1.8 million compared to the prior year due to the sale of two aircraft from our joint venture aircraft portfolio during the prior year.

Operating income decreased $2.9 million or 2.2% compared with the prior year primarily due to increased selling, general and administrative expenses, partially offset by increased gross profit in the Technology Products segment.

Net interest expense increased $6.2 million or 20.5% compared to the prior year primarily due to an increase in outstanding borrowings incurred for the purchase of Telair and Nordisk.

Our effective income tax rate was 27.2% in fiscal 2012 compared to 32.5% in fiscal 2011. During the fourth quarter of fiscal 2012, we recorded a $3.3 million reduction in income tax expense primarily relating to revisions in book versus tax differences. During the third quarter of fiscal 2012, we recorded a $4.0 million reduction in income tax expense primarily relating to a reduction in our state income tax rate due to the implementation of state income tax planning strategies related to our corporate structure and the relocation of one of our significant units. During the fourth quarter of fiscal 2011, we recorded a net $2.3 million tax benefit, which was primarily the result of a $3.5 million federal income tax benefit as a result of the completion of an examination of our income tax returns from fiscal 2007 through fiscal 2009.

During fiscal 2012, we retired $9.4 million principal amount of our 1.625% convertible notes resulting in a net loss of $0.2 million. We also retired $20.6 million principal amount of our 1.75% convertible notes resulting in a net loss of $0.2 million. During fiscal 2012 and 2011, we retired $9.1 million and $6.0 million principal amount of our 2.25% convertible notes resulting in a net loss of $0.3 million and a gain of $0.1 million for years 2012 and 2011, respectively.

Net income attributable to AAR was $67.7 million compared to $69.8 million in the prior year due to the factors discussed above.

Liquidity, Capital Resources and Financial Position

Our operating activities are funded and commitments met through the generation of cash from operations. Periodically, we may raise capital through the issuance of common stock and debt financing in the public and private markets. In addition to these cash sources, our current capital resources include an unsecured credit facility, as well as a separate secured credit facility. We continually evaluate various financing arrangements, including the issuance of common stock or debt, which would allow us to improve our liquidity position and finance future growth on commercially reasonable terms. Our continuing ability to borrow from our lenders and issue debt and equity securities to the public and private markets in the future may be negatively affected by a number of factors, including the overall health of the credit markets, general economic conditions, airline industry conditions, geo-political events, and our operating performance. Our ability to generate cash from operations is influenced primarily by our operating performance and changes in working capital. Under our universal shelf registration statement filed with the Securities and Exchange Commission that became effective May 4, 2012, we registered an indeterminate number of principal amount or shares of common stock, shares of preferred stock, debt securities, warrants, stock purchase contracts and stock purchase units which may be sold from time to time, subject to market conditions.

At May 31, 2013, our liquidity and capital resources included cash of $75.3 million and working capital of $644.7 million. On April 24, 2013, we amended our agreement with various financial institutions, as lenders, and Bank of America, N.A., as administrative agent for the lenders (as amended, the "Credit Agreement"), reducing the aggregate revolving credit commitment under the Credit Agreement from $580.0 million to $475.0 million, and extending the maturity by approximately two years to April 24, 2018. Borrowings under the Credit Agreement bear interest at the offered Eurodollar Rate (defined as the British Bankers Association LIBOR Rate) plus 125 to 225 basis points based on certain financial measurements if a Eurodollar Rate loan, or at the offered fluctuating Base Rate plus 25 to 125 basis points based on certain financial measurements if a Base Rate loan. Borrowings outstanding under this facility at May 31, 2013 were $120.0 million and there were approximately $17.8 million of outstanding letters of credit, which reduced the availability of this facility to $337.2 million. There are no other terms or covenants limiting the availability of this facility. We also have $5.2 million available under a foreign line of credit.

In addition to our unsecured Credit Agreement, on March 28, 2013, we amended our secured revolving credit facility with The Huntington National Bank (the "Huntington Loan Agreement"). The amendment to the Huntington Loan Agreement reduced our secured revolving facility from $65.0 million to $40.0 million while also reducing the interest rate from 325 basis points to 175 basis points over LIBOR. Borrowings under the Huntington Loan Agreement are secured by aircraft and related engines and components owned by us. The Huntington Loan Agreement expires on April 23, 2015. As of May 31, 2013 and 2012, $39.2 million and $33.0 million, respectively, were outstanding under this agreement. There are no other terms or covenants limiting the availability of this facility.

On April 15, 2013, we completed an add-on offering of $150.0 million aggregate principal amount of our 7.25% Senior Notes due 2022 (the "Notes"). The Notes were sold in a private placement to qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933, as amended (the

Table of Contents

"Securities Act"), and outside the United States to non-U.S. persons in accordance with Regulation S under the Securities Act. The Notes were sold at a price equal to 107.5% of the principal amount thereof, for a yield to maturity of 6.128%. The net proceeds of the offering of the Notes after expenses were $157.6 million, and were used to repay a portion of the borrowings under our unsecured revolving credit agreement.

The Notes were issued under the indenture dated January 23, 2012, as supplemented as of November 30, 2012 (the "Indenture"), pursuant to which we issued $175.0 million aggregate principal amount of our 7.25% Senior Notes due 2022 (the "Original Notes"). The Notes will be treated as a single series with the Original Notes and have the same terms as those of the Original Notes, except for certain provisions related to registration rights. The Notes and Original Notes will vote as one class under the Indenture.

On February 14, 2013, we completed an exchange agreement with an institutional holder to exchange $22.7 million aggregate principal amount of our 1.75% Convertible Senior Notes, plus cash in the amount of $7.3 million for a new $30.0 million convertible note (the "New Note"). The New Note was issued in a private placement, is subject to customary resale restrictions, and has no registration rights. The New Note matures on February 1, 2015 unless redeemed earlier by us with a 30 days' notice to the holder at a call price reflecting a yield to maturity of 3.75% from inception. We may redeem the New Note at any time before February 1, 2014 in the event of a change in control or at any time from February 1, 2014 through February 1, 2015 with a call price at maturity of 104.038%. Upon conversion, the holder of the New Note shall be entitled to receive only cash and not shares of common stock. The New Note bears interest at a coupon rate of 1.75% per year, payable semi-annually on February 1 and August 1.

We are in compliance with all financial covenants under each of our financing arrangements.

Cash Flows from Operating Activities

During fiscal 2013, our cash flow from operations was $162.9 million primarily as a result of net income attributable to AAR and non-controlling interest and aggregate depreciation and amortization. These positive impacts were partially offset by capitalized program and overhaul costs and a decrease in accounts payable as we reduced the number of days in accounts payable during fiscal 2013.

Cash flow from operations increased $68.7 million from the prior year due to lower investments in inventory and reduced program and overhaul costs, partially offset by a reduction in accounts payable in fiscal 2013.

Cash Flows from Investing Activities

During fiscal 2013, our investing activities used $32.8 million of cash. Cash outflows during fiscal 2013 related to capital expenditures of $37.6 million and $21.3 million of final payments for the acquisition of Telair, Nordisk, and Airinmar. These cash outflows were partially offset by proceeds from aircraft joint ventures representing a return of capital and proceeds from sales of equipment.

Cash flow from investing activities improved $357.4 million from the prior year as the prior year included cash paid for the Telair, Nordisk, and Airinmar acquisitions, and a decrease in our capital expenditures in all of our units as we focus on the generation of cash.

Cash Flows from Financing Activities

During fiscal 2013, our financing activities used $123.7 million of cash primarily due to a reduction in borrowings of $274.3 million, the repurchase of common stock under our share repurchase program of $14.6 million, and payment of dividends of $12.8 million. Proceeds from our borrowings during fiscal 2013 were $181.8 million. In the prior year we had cash inflows from net borrowing of $333.3 million and we used these proceeds to purchase Telair, Nordisk, and Airinmar.

We routinely issue letters of credit and performance bonds in the ordinary course of business. These instruments are typically issued in conjunction with insurance contracts or other business requirements. The total of these instruments outstanding at May 31, 2013 was $17.8 million.

Critical Accounting Policies and Significant Estimates

Our Consolidated Financial Statements are prepared in conformity with accounting principles generally accepted in the United States. Management has made estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent liabilities to prepare the Consolidated Financial Statements. The most significant estimates made by management include those related to the allowance for doubtful accounts, assumptions used in assessing goodwill impairment, adjustments to reduce the value of inventories and aviation equipment on or available for lease, revenue recognition, loss accruals for aviation equipment operating leases, program development costs and assumptions used in determining pension plan obligations. Accordingly, actual results could differ materially from those estimates. The following is a summary of the accounting policies considered critical by management.

Allowance for Doubtful Accounts

Our allowance for doubtful accounts is intended to reduce the value of customer accounts receivable to amounts expected to be collected. In determining the required allowance, we consider factors such as general and industry-specific economic conditions, customer credit history, and our customer's current and expected future financial performance.

Table of Contents

Goodwill and Other Intangible Assets

Under accounting standards for goodwill and other intangible assets, goodwill and other intangible assets deemed to have indefinite lives are not amortized, but are subject to annual impairment tests. We review and evaluate our goodwill and indefinite life intangible assets for potential impairment at a minimum annually, on May 31, or more frequently if circumstances indicate that impairment is possible. We use a two-step process to evaluate goodwill for impairment. In the first step, we compare the fair value of each reporting unit with the carrying value of the reporting unit, including goodwill. We estimate the fair value of each reporting unit using a valuation technique based on a multiple of earnings or discounted cash flows. If the estimated fair value of the reporting unit is less than the carrying value of the reporting unit, we would be required to complete a second step to determine the amount of goodwill impairment. The second step of the test requires the allocation of the reporting unit's fair value to its assets and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill as if the reporting unit was being acquired in a business combination. If the implied fair value of goodwill is less than the carrying value, the difference is recorded as an impairment loss.

The assumptions we used to estimate the fair value of our reporting units are based on historical performance as well as forecasts used in our current business plan.

Inventories

Inventories are valued at the lower of cost or market. Cost is determined by the specific identification, average cost or first-in, first-out methods. Write-downs are made for excess and obsolete inventories and inventories that have been impaired as a result of industry conditions. We have utilized certain assumptions when determining the market value of inventories, such as historical sales of inventory, current and expected future aviation usage trends, replacement values and expected future demand. Reductions in demand for certain of our inventories or declining market values, as well as differences between actual results and the assumptions utilized by us when determining the market value of our inventories, could result in the recognition of impairment charges in future periods.

Revenue Recognition

Certain supply chain management programs that we provide to our customers contain multiple elements or deliverables, such as program and warehouse management, parts distribution and maintenance and repair services. We recognize revenue for each element or deliverable that can be identified as a separate unit of accounting at the time of delivery based upon the relative fair value of the products and services.

Sales and related cost of sales for certain long-term manufacturing contracts and certain large airframe maintenance contracts and performance-based logistics programs are recognized by the percentage of completion method, based on either the relationship of costs incurred to date to estimated total costs or the units of delivery method. In connection with these contracts and programs, we are required to make certain judgments and estimates, including estimated revenues and costs, as well as inflation and the overall profitability of the program and the relative fair value of each element of the arrangement. Differences may occur between the judgments and estimates made by management and actual program results.

Equipment on or Available for Lease

The cost of assets under lease is original purchase price plus overhaul costs. Depreciation is computed using the straight-line method over the estimated service life of the equipment, and maintenance costs are expensed as incurred.

Table of Contents

We are required to test for impairment of long-lived assets whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable from its undiscounted cash flows. When applying accounting standards addressing impairment to equipment on or available for lease, we have utilized certain assumptions to estimate future undiscounted cash flows, including current and future lease rates, lease terms, residual values and market conditions and trends impacting future demand. Differences between actual results and the assumptions utilized by us when determining undiscounted cash flows could result in future impairments of aircraft and engines which are currently being leased or are available for lease. During the fourth quarter of fiscal 2011, we recorded a $5.3 million pre-tax impairment charge to reduce the carrying value of an aircraft held for sale to its fair value (See Note 12 of Notes to Consolidated Financial Statements).

Program Development Costs

Our Cargo Systems unit was selected in June 2005 to provide cargo loading systems for the Airbus A400M Military Transport Aircraft ("A400M"). During fiscal 2013, we delivered initial production units to Airbus, and we expect to deliver revenue-producing units beginning late in the first quarter or early in the second quarter of fiscal 2014. We expect our portion of the revenue from this program to be approximately $250 million through fiscal 2020, based on current sales projections of the A400M and the agreed-upon fixed pricing for the items that we are now responsible for under the amended contract.

As of May 31, 2013 and 2012, we have capitalized, net of reimbursements, $130.9 million and $91.9 million, respectively, of costs associated with the engineering and development of the cargo system. Sales and related cost of sales will be recognized on the units of delivery method. In determining the recoverability of the capitalized program development costs, we have made certain judgments and estimates concerning expected revenues and the cost to manufacture the A400M cargo system. Differences between actual results and our assumptions may result in our not fully recovering our program development costs, which could adversely affect our operating results and financial condition.

Pension Plans

The liabilities and net periodic cost of our pension plans are determined utilizing several actuarial assumptions, the most significant of which are the discount rate and the expected long-term rate of return on plan assets.

AAR uses a discount rate to measure our benefit obligation for our pension plans. This discount rate will be used in calculating the net periodic benefit cost for these plans for fiscal 2014. We used a broad population of Aa-rated corporate bonds as of May 31, 2013 to determine the discount rate assumption. All bonds were denominated in U.S. Dollars, with a minimum outstanding of $50.0 million. This population of bonds was narrowed from a broader universe of over 500 Moody's Aa-rated, non-callable (or callable with make-whole provisions) bonds by eliminating the top 10 ^th percentile and the bottom 40 ^th percentile to adjust for any pricing anomalies and to represent the bonds we would most likely select if we were to actually annuitize our pension plan liabilities. This portfolio of bonds was used to generate a yield curve and associated spot rate curve to discount the projected benefit payments for the domestic plans. The discount rate is the single level rate that produces the same result as the spot rate curve.

We establish the long-term asset return assumption based on a review of historical compound average asset returns, both company-specific and relating to the broad market, as well as analysis of current market and economic information and future expectations. The current asset return assumption is supported by historical market experience for both our actual and target asset allocation. In calculating the net pension cost, the expected return on assets is applied to a calculated value on plan assets, which recognizes changes in the fair value of plan assets in a systematic manner over five years. The difference between this expected return and the actual return on plan assets is a component of the total net unrecognized gain or loss and is subject to amortization in the future.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
(Dollars in millions)

Our exposure to market risk includes fluctuating interest rates under our credit agreements, changes in foreign exchange rates, and credit losses on accounts receivable. See Note 1 of Notes to Consolidated Financial Statements for a discussion on accounts receivable exposure.

We are exposed to the risk that our earnings and cash flows could be adversely impacted by fluctuations in interest rates. We manage interest costs by using a mix of fixed- and floating-rate debt. We utilize two derivative financial instruments to manage our variable interest rate exposure over a medium- to long-term period. We have a floating-to-fixed interest rate swap and an interest rate cap agreement.

A 10 percent increase to the average interest rate affecting our financial instruments, including the average outstanding balance of our debt obligations and related derivatives, would have reduced our pre-tax income by approximately $1 million during fiscal 2013.

Revenues and expenses of our foreign operations are translated at average exchange rates during the year, and balance sheet accounts are translated at year-end exchange rates. Balance sheet translation adjustments are excluded from the results of operations and are recorded in stockholders' equity as a component of accumulated other comprehensive loss. A hypothetical 10 percent devaluation of the U.S. dollar against foreign currencies would have decreased pre-tax income by approximately $6.0 million in 2013.

1. Summary of Significant Accounting Policies

Description of Business

AAR CORP. is a diversified provider of products and services to the worldwide commercial aviation and government and defense markets. Products and services include: aviation supply chain and parts support programs; maintenance, repair and overhaul of aircraft and landing gear; design and manufacture of specialized mobility and cargo systems and composite and other high-end precision machined structures; expeditionary airlift services; aircraft modifications and aircraft and engine sales and leasing. We serve commercial, defense and governmental aircraft fleet operators, original equipment manufacturers, and independent service providers around the world, and various other domestic and foreign military customers.

Principles of Consolidation

The accompanying Consolidated Financial Statements include the accounts of the Company and its majority-owned subsidiaries after elimination of intercompany accounts and transactions. The equity method of accounting is used for investments in other companies in which we have significant influence; generally this represents common stock ownership of at least 20% and not more than 50% (see Note 9 for a discussion of aircraft joint ventures).

Revenue Recognition

Sales and related cost of sales for product sales are recognized upon shipment of the product to the customer. Our standard terms and conditions provide that title passes to the customer when the product is shipped to the customer. Sales of certain defense products are recognized upon customer acceptance, which includes transfer of title. Under the majority of our expeditionary airlift services contracts, we are paid and record as revenue a fixed daily amount per aircraft for each day an aircraft is available to perform airlift services. In addition, we are paid and record as revenue an amount which is based on number of hours flown. Sales from services and the related cost of services are generally recognized when customer-owned material is shipped back to the customer. We have adopted this accounting policy because at the time the customer-owned material is shipped back to the customer, all services related to that material are complete as our service agreements generally do not require us to provide services at customer sites. Furthermore, serviced units are typically shipped to the customer immediately upon completion of the related services. Sales and related cost of sales for certain long-term manufacturing contracts, certain large airframe maintenance contracts, and performance-based logistics programs are recognized by the percentage of completion method, either based on the relationship of costs incurred to date to the estimated total costs or the units of delivery method. Lease revenues are recognized as earned. Income from monthly or quarterly rental payments is recorded in the pertinent period according to the lease agreement. However, for leases that provide variable rents, we recognize lease income on a straight-line basis. In addition to a monthly lease rate, some engine leases require an additional rental amount based on the number of hours the engine is used in a particular month. Lease income associated with these contingent rentals is recorded in the period in which actual usage is reported to us by the lessee, which is normally the month following the actual usage.

Certain supply chain management programs we provide to our customers contain multiple elements or deliverables, such as program and warehouse management, parts distribution, and maintenance and

1. Summary of Significant Accounting Policies (Continued)

repair services. We recognize revenue for each element or deliverable that can be identified as a separate unit of accounting at the time of delivery based upon the relative fair value of the products and services.

Included in accounts receivable as of May 31, 2013 and 2012, are $28.4 million and $36.2 million, respectively, of unbilled accounts receivable related to our KC10 supply agreement. These unbilled accounts receivable relate to costs we have incurred on parts that were requested and accepted by our customer to support the program. These costs have not been billed by us because the customer has not issued the final paperwork necessary to allow for billing.

In addition to the unbilled accounts receivable, included in Other non-current assets on the consolidated balance sheet as of May 31, 2013 and 2012, are $9.9 million and $27.9 million, respectively, of costs in excess of amounts billed for the flight-hour portion of the same KC10 supply agreement. These amounts represent the difference between the amount of revenue recognized by us driven by costs incurred under the flight hour portion of the program, compared to what was billed. These amounts are after adjustments recorded during fiscal 2013 and 2012, as more fully described below.

Pursuant to U.S. generally accepted accounting principles, we have to assess the recoverability of the costs in excess of amounts billed by projecting future performance of the flight hour portion of the contract, including an estimate of future flight hours and costs over the life of the program. In fiscal 2012, we reduced the profit margin on the flight-hour portion of the contract from 8% to 2% due to higher than expected costs incurred by us to support the fleet, resulting in a $9.5 million pre-tax charge.

As we entered fiscal 2013, to support the 2% margin we established cost savings targets to reduce program spend over the life of the program. We exceeded our first year targeted savings and are on track to achieve the fiscal 2014 savings target. However, beginning in the second half of fiscal 2013 we experienced a decrease in flight hour revenue. This decrease was caused by a 28% decline in flight hours flown due to lower operations tempo and, we believe, the effects of sequestration. As a result of this unexpected and significant decline in flight hour revenue, together with our revised forecast for future usage of the fleet (which is below our previous forecast and historical usage), we further lowered the revenue and profitability forecast for the flight hour portion of the contract, resulting in a $29.8 million pre-tax charge during the fourth quarter of fiscal 2013. In fiscal 2014, we will record 0% margin on the flight-hour portion of the contract, which is estimated to be approximately $45 million of revenue. We expect to recover the May 31, 2013 balance of the costs in excess of amounts billed of $9.9 million through projected future billings and by identifying additional cost savings opportunities over the life of the program. Non-flight hour revenue associated with the program are estimated to be approximately $35 to $40 million in fiscal 2014 at normal profit margins.

Notwithstanding the foregoing, we reserve all our rights under the KC10 supply agreement, at law and in equity, including our rights to recover past and future revenues and expenses associated with the program.

Goodwill and Other Intangible Assets

AAR CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Dollars in millions, except per share amounts)

1. Summary of Significant Accounting Policies (Continued)

We use a two-step process to evaluate goodwill for impairment. In the first step, we compare the fair value of each reporting unit with the carrying value of the reporting unit, including goodwill. We estimate the fair value of each reporting unit using a valuation technique based on a multiple of earnings or discounted cash flows. If the estimated fair value of the reporting unit is less than the carrying value of the reporting unit, we would be required to complete a second step to determine the amount of goodwill impairment. The second step of the test requires the allocation of the reporting unit's fair value to its assets and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill as if the reporting unit was being acquired in a business combination. If the implied fair value of goodwill is less than the carrying value, the difference is recorded as an impairment loss.

The assumptions we used to estimate the fair value of our reporting units are based on historical performance, as well as forecasts used in our current business plan and require considerable management judgment. The fair value measurements used for our goodwill impairment testing use significant unobservable inputs, which reflect our own assumptions about the inputs that market participants would use in measuring fair value. The fair value of our reporting units is also impacted by our overall market capitalization and may be impacted by volatility in our stock price and assumed control premium, among other items.

As of May 31, 2013, we have five reporting units as defined by the accounting standard for goodwill. Step one of the impairment test concluded for all of our reporting units the estimated fair value exceeded its net asset carrying value. Accordingly, there was no indication of impairment and the second step was not performed.

Goodwill by segment is as follows:

	May 31,

	2013		2012
Aviation Services	$	91.9	$	93.0
Technology Products		163.7		169.6

Intangible assets, other than goodwill, are comprised of the following:

	May 31,

	2013			2012
Amortizable intangible assets:
Customer relationships	$	108.0		$	113.4
Developed technology		31.0			30.0
Lease agreements		21.5			21.5
FAA certificates		5.0			5.0
Other		—			2.5

		140.4			138.3
Unamortized intangible assets:
Trademarks		17.4			16.7

	$	157.8		$	155.0

Customer relationships are being amortized over 1-20 years, developed technology is being amortized over 7-30 years, the lease agreements are being amortized over 18 years, and the FAA certificates are being amortized over 20 years. Amortization expense recorded during fiscal 2013, 2012 and 2011 was $13.7 million, $13.0 million, and $9.6 million, respectively. The estimated aggregate amount of amortization expense for intangible assets in each of the next five fiscal years is $9.0 million in 2014, $8.9 million in 2015, $8.8 million in 2016, $8.8 million in 2017 and $8.8 million in 2018.

Foreign Currency

Our foreign subsidiaries utilize the local currency as their functional currency. All balance sheet accounts of foreign subsidiaries transacting business in currencies other than the U.S. dollar are translated at year-end exchange rates. Revenues and expenses are translated at average exchange rates during the year. Translation adjustments are excluded from the results of operations and are recorded in stockholders' equity as a component of accumulated other comprehensive loss.

Financial Instruments and Concentrations of Market or Credit Risk

Financial instruments that potentially subject us to concentrations of market or credit risk consist principally of trade receivables. While our trade receivables are diverse and represent a number of entities and geographic regions, the majority are with the U.S. Department of Defense and its contractors and entities in the aviation industry. Accounts receivable due from the U.S. Department of Defense were $49.3 million and $50.6 million at May 31, 2013 and 2012, respectively. Additionally, included in accounts receivable as of May 31, 2013 and 2012, are $56.0 million and $47.2 million, respectively, of accounts receivable from a large defense contractor. We perform regular evaluations of customer payment experience, current financial condition, and risk analysis. We may require collateral in the form of security interests in assets, letters of credit, and/or obligation guarantees from financial institutions for transactions executed on other than normal trade terms.

1. Summary of Significant Accounting Policies (Continued)

The carrying amounts of cash and cash equivalents, accounts receivable, short-term borrowings, and accounts and trade notes payable approximate fair value because of the short-term maturity of these instruments. The carrying value of long-term debt bearing a variable interest rate approximates fair value.

Fair value estimates are made at a specific point in time based on relevant market information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Inventories

Inventories are valued at the lower of cost or market (estimated net realizable value). Cost is determined by the specific identification, average cost, or first-in, first-out methods. From time-to-time, we purchase aircraft and engines for disassembly to individual parts and components. Costs are assigned to these individual parts and components utilizing list prices from original equipment manufacturers and recent sales history.

The following is a summary of inventories:

	May 31,

	2013		2012
Raw materials and parts	$	83.9	$	101.3
Work-in-process		84.0		64.7
Aircraft and engine parts, components and finished goods		285.8		295.2

	$	453.7	$	461.2

Equipment under Leases

Lease revenue is recognized as earned. The cost of the asset under lease is the original purchase price plus overhaul costs. Depreciation for aircraft is computed using the straight-line method over the estimated service life of the equipment. The balance sheet classification of equipment under lease is generally based on lease term, with fixed-term leases less than twelve months generally classified as short-term and all others generally classified as long-term.

Equipment on short-term lease includes aircraft engines and parts on or available for lease to satisfy customers' immediate short-term requirements. The leases are renewable with fixed terms, which generally vary from one to twelve months. Equipment on long-term lease consists of aircraft and engines on lease with commercial airlines generally for more than twelve months.

We are required to test for impairment of long-lived assets whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable from its undiscounted cash flows. When applying accounting standards addressing impairment to our aircraft and engine portfolio, we utilize certain assumptions to estimate future undiscounted cash flows, including current and future lease rates, lease terms, residual values and market conditions and trends impacting future demand (see Note 12—Restructuring and Impairment Charges). Unfavorable differences between actual and expected results could result in future impairments in our aircraft and engine lease portfolio.

1. Summary of Significant Accounting Policies (Continued)

Future rent due to us under non-cancelable leases during each of the next five fiscal years is $13.3 million in 2014, $12.5 million in 2015, $10.9 million in 2016, $10.7 million in 2017, and $10.5 million in 2018.

Property, Plant and Equipment

Depreciation is computed on the straight-line method over useful lives of 10-40 years for buildings and improvements and 3-10 years for equipment, furniture and fixtures, and capitalized software. Aircraft and major components in service to support our Airlift unit are depreciated over their estimated useful lives, which is generally 7-20 years. Leasehold improvements are amortized over the shorter of the estimated useful life or the term of the applicable lease.

Repair and maintenance expenditures are expensed as incurred. Upon sale or disposal, cost and accumulated depreciation are removed from the accounts, and related gains and losses are included in results of operations.

Supplemental Information on Cash Flows

Supplemental information on cash flows follows:

	For the Year Ended May 31,

	2013		2012		2011

Income taxes paid		24.1		11.4		9.8
Income tax refunds and interest received		23.2		7.2		4.5

During fiscal 2013 treasury stock increased $9.7 million reflecting the purchase of treasury shares of $14.6 million, partially offset by the re-issuance of shares upon exercise of stock options, net of shares withheld to satisfy statutory tax obligations, and restricted stock award grants of $4.9 million. During fiscal 2012 Treasury stock decreased $10.0 million reflecting the re-issuance of shares upon exercise of stock options, net of shares withheld to satisfy statutory tax obligations, and restricted stock award grants of $13.7 million, partially offset by the purchase of treasury shares of $3.7 million. During fiscal 2011 Treasury stock decreased $4.0 million reflecting the re-issuance of shares upon exercise of stock options, net of shares withheld to satisfy statutory tax obligations, and restricted stock award grants of $6.6 million, partially offset by the purchase of treasury shares of $2.5 million and the impact of net share settlements of $0.1 million of bond hedge and warrants associated with convertible bond repurchases during fiscal 2011.

Use of Estimates

We have made estimates and utilized certain assumptions relating to the reporting of assets and liabilities and the disclosures of contingent liabilities to prepare these Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States. Actual results could differ from those estimates.

At May 31, 2013, the face value of our debt was $709.7 million and the estimated fair value was approximately $735.0 million. The fair value amounts of our long-term debt securities are estimated using significant other observable inputs including quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. The debt is classified as Level 2 in the fair value hierarchy.

Revolving Credit Facilities

On April 24, 2013, we amended our agreement with various financial institutions, as lenders, and Bank of America, N.A., as administrative agent for the lenders (as amended, the "Credit Agreement"), reducing the aggregate revolving credit commitment under the Credit Agreement from $580.0 million to

$475.0 million, and extending the maturity by approximately two years to April 24, 2018. Borrowings under the Credit Agreement bear interest at the offered Eurodollar Rate (defined as the British Bankers Association LIBOR Rate) plus 125 to 225 basis points based on certain financial measurements if a Eurodollar Rate loan, or at the offered fluctuating Base Rate plus 25 to 125 basis points based on certain financial measurements if a Base Rate loan. Borrowings outstanding under this facility at May 31, 2013 were $120.0 million and there were approximately $17.8 million of outstanding letters of credit, which reduced the availability of this facility to $337.2 million. There are no other terms or covenants limiting the availability of this facility. We also have $5.2 million available under a foreign line of credit.

Borrowing activity under the Credit Agreement during fiscal 2013, 2012 and 2011 was as follows:

	For the Year Ended May 31,

	2013			2012			2011
Maximum amount borrowed	$	395.0		$	525.0		$	135.0
Average daily borrowings		312.3			288.3			70.6
Average interest rate during the year		2.03	%		1.90	%		1.95	%

On March 28, 2013, we amended our secured revolving credit facility with The Huntington National Bank (the "Huntington Loan Agreement"). The amendment to the Huntington Loan Agreement reduced our secured revolving facility from $65.0 million to $40.0 million while also reducing the interest rate from 325 basis points to 175 basis points over LIBOR. Borrowings under the Huntington Loan Agreement are secured by aircraft and related engines and components owned by us. The Huntington Loan Agreement expires on April 23, 2015. As of May 31, 2013 and 2012, $39.2 million and $33.0 million, respectively, were outstanding under this agreement.

The Credit Agreement requires us to comply with certain financial covenants, including a fixed charge coverage ratio and a leverage ratio. The Credit Agreement contains certain affirmative and negative covenants, including those relating to financial reporting and notification, payment of indebtedness, taxes and other obligations, compliance with applicable laws, and limitations on additional liens, indebtedness, acquisitions, investments and disposition of assets. The Credit Agreement also requires our significant domestic subsidiaries, and any subsidiaries that guarantee our other indebtedness, to provide a guarantee of payment under the Credit Agreement.

The Huntington Loan Agreement requires us to comply with certain financial covenants which are consistent with our Credit Agreement and it is not guaranteed by our subsidiaries. The Huntington Loan Agreement also contains certain affirmative and negative covenants, including those relating to financial reporting and notification, payment of indebtedness, taxes and other obligations, compliance with applicable laws, and limitations on additional liens, indebtedness, acquisitions, investments and disposition of assets.

At May 31, 2013, we were in compliance with the financial covenants in these agreements.

The net proceeds of the offering of the Notes after expenses were $157.6 million, and were used to repay a portion of the borrowings under our unsecured revolving credit agreement.

On February 14, 2013, we completed an exchange agreement with an institutional holder to exchange $22.7 million aggregate principal amount of our 1.75% Convertible Senior Notes, plus cash in the amount of $7.3 million for a new $30.0 million convertible note (the "New Note"). The New Note was issued in a private placement, is subject to customary resale restrictions, and has no registration rights. The New Note matures on February 1, 2015 unless redeemed earlier by us with 30 days' notice to the holder at a call price reflecting a yield to maturity of 3.75% from inception. We may redeem the New Note at any time before February 1, 2014 in the event of a change in control or at any time from February 1, 2014 through February 1, 2015 with a call price at maturity of 104.038%. Upon conversion, the holder of the New Note shall be entitled to receive only cash and not shares of common stock. The New Note bears interest at a coupon rate of 1.75% per year, payable semi-annually on February 1 and August 1.

On January 22, 2013, we exchanged all of the outstanding unregistered 7.25% Senior Notes due 2022, which we issued in an exempt offering on January 23, 2012, for substantially identical notes that were registered under the Securities Act of 1933. These notes are now fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by substantially all of our existing domestic and foreign subsidiaries.

Debt Retirements

During fiscal 2013 and 2012, we retired a portion of the following debt instruments:

	Principal Amount				Cash Paid				Loss on Repurchase

	2013		2012		2013		2012		2013		2012
1.625% convertible notes due March 1, 2014	$	6.4	$	9.4	$	6.1	$	8.9	$	0.1	$	0.2
2.25% convertible notes due March 1, 2016		5.5		9.1		4.9		8.1		0.2		0.3

2. Financing Arrangements (Continued)

In addition to the aforementioned debt retirements, during fiscal 2013, pursuant to the terms of the applicable indenture, certain holders of our 1.75% Convertible Senior Notes due 2026 (the "Securities") exercised the right to surrender their Securities for purchase by us (the "Put Option"). The Put Option entitled each holder of the Securities to surrender to us for purchase all or any part of such holder's Securities at a purchase price equal to 100% of the principal amount, plus accrued interest. The aggregate purchase price including principal, accrued and unpaid interest for the Securities surrendered for purchase pursuant to the Put Option was $66.2 million. The purchases were funded primarily by cash on hand and free cash flow during the third quarter of fiscal 2013. There was no gain or loss on the repurchase of these notes.

Convertible Notes

As of May 31, 2013 and 2012, the short-term and long-term debt and equity component (recorded in capital surplus, net of income tax benefit) consisted of the following:

	May 31,

	2013			2012
Long-term debt:
Principal amount	$	148.3		$	229.3
Unamortized discount		(9.5	)		(19.8	)

Net carrying amount	$	138.8		$	209.5

Equity component, net of tax	$	75.3		$	74.8

The discount on the liability component of long-term debt is being amortized using the effective interest method based on an effective rate. For fiscal years 2013 and 2012, the effective interest rate for our convertible debt was as follows:

	May 31,

	2013			2012
1.625% convertible notes due March 1, 2014		6.82	%		6.82	%
1.75% convertible notes due February 1, 2015		5.00	%		—
2.25% convertible notes due March 1, 2016		7.41	%		7.41	%
1.75% convertible notes due February 1, 2026		—			8.48	%

For our 1.625%, 1.75% and 2.25% convertible notes, the discount is being amortized through their respective maturity dates of March 1, 2014, February 1, 2015 and March 1, 2016. For our 1.75% convertible notes due February 1, 2026, the discount was amortized through February 1, 2013, which was the first put date for those notes. As of May 31, 2013 and 2012, for each of our convertible note issuances, the "if converted" value does not exceed its principal amount.

2. Financing Arrangements (Continued)

The interest expense associated with the convertible notes was as follows:

	For the Year Ended May 31,

	2013		2012		2011
Coupon interest	$	3.7	$	4.9	$	4.9
Amortization of deferred financing fees		0.5		0.7		0.8
Amortization of discount		9.3		13.1		12.3

Interest expense related to convertible notes	$	13.5	$	18.7	$	18.0

We are subject to a number of covenants under our financing arrangements, including restrictions that relate to the payment of cash dividends, maintenance of minimum net working capital and tangible net worth levels, fixed charge coverage ratio, sales of assets, additional financing, purchase of our shares and other matters. We are in compliance with all financial covenants under our financing arrangements.

3. Derivative Instruments and Hedging Activities

We are exposed to interest rate risk associated with fluctuations in interest rates on our variable rate debt. We utilize two derivative financial instruments to manage our variable interest rate exposure over a medium- to long-term period. We have a floating-to-fixed interest rate swap and an interest rate cap agreement, each hedging $50.0 million of notional principal interest under our revolving Credit Agreement.

We do not hold or issue derivative instruments for trading purposes and are not a party to any instruments with leverage or prepayment features. In connection with derivative financial instruments, there exists the risk of the possible inability of counterparties to meet the terms of their contracts. We mitigate this risk by performing financial reviews before the contract is entered into, as well as on-going periodic evaluations. We do not expect any significant losses from counterparty defaults.

We classify the derivatives as assets or liabilities on the balance sheet. Accounting for the change in fair value of the derivatives is a function of whether the instrument qualifies for, and has been designated as, a hedging relationship, and the type of hedging relationship. As of May 31, 2013, all of our derivative instruments were classified as cash flow hedges. The fair value of the interest rate swap and interest rate cap agreements represents the difference in the present values of cash flows calculated at the contracted interest rates and at current market interest rates at the end of the reporting period.

We record the fair value of assets and liabilities in accordance with the hierarchy established by the authoritative guidance for fair value measurements. The fair value of our interest rate derivatives are classified as Level 2, which refers to fair values estimated using significant other observable inputs including quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. The following tables summarize the classification

3. Derivative Instruments and Hedging Activities (Continued)

and fair values of our interest rate derivative instruments reported in the Consolidated Balance Sheet at May 31, 2013 and May 31, 2012.

		Derivative Assets		Derivative Liabilities

	Balance Sheet Classification	Derivative Assets		Derivative Liabilities
Derivatives designated as hedging instruments:	Balance Sheet Classification	May 31, 2013		May 31, 2013
Interest rate cap	Long-term assets	$	0.1	$	—
Interest rate swap	Long-term liabilities		—		(3.6	)

Interest rate cap	Long-term assets	$	0.2	$	—
Interest rate swap	Long-term liabilities		—		(4.5	)

We include gains and losses on the derivative instruments in other comprehensive income. We recognize the gains and losses on our derivative instruments as an adjustment to interest expense in the period the hedged interest payment affects earnings. The impact of the interest rate swap and interest cap agreement on the Consolidated Statement of Comprehensive Income for the years ended May 31, 2013 and 2012 was an unrealized gain of $0.6 million and an unrealized loss of $3.9 million, respectively. We expect minimal gain or loss to be reclassified into earnings within the next 12 months.

4. Stock-Based Compensation

We provide stock-based awards under the AAR CORP. Stock Benefit Plan ("Stock Benefit Plan") which has been approved by our stockholders. Under the Stock Benefit Plan, we are authorized to issue stock options to employees and non-employee directors that allow the grant recipients to purchase shares of common stock at a price not less than the fair market value of the common stock on the date of grant. Generally, stock options awarded expire ten years from the date of grant and are exercisable in three, four or five equal annual increments commencing one year after the date of grant. In addition to stock options, the Stock Benefit Plan also provides for the grant of restricted stock awards and performance-based restricted stock awards. The number of performance-based awards earned, subject to vesting, is based on achievement of certain Company-wide financial goals or stock price targets. The Stock Benefit Plan also provides for the grant of stock appreciation units and restricted stock units; however, to date, no such awards have been granted.

Restricted stock grants are designed, among other things, to align employee interests with the interests of stockholders and to encourage the recipient to build a career with us. Restricted stock typically vests over periods of one to five years from date of grant. Restricted stock grants may be performance-based with vesting to occur over periods of three to six years. All restricted stock that has been granted and earned according to performance criteria carries full dividend and voting rights, regardless of whether it has vested.

Typically, stock options and restricted stock are subject to forfeiture prior to vesting if the employee's employment terminates for any reason other than death, disability or retirement. A total of 9,949,000

4. Stock-Based Compensation (Continued)

shares have been granted under the Stock Benefit Plan since its inception, and as of May 31, 2013, a total of 1,259,000 shares were available for future grant under the Stock Benefit Plan.

Stock Options

During fiscal 2013, 2012 and 2011, we granted stock options representing 972,180 shares, 169,281 shares, and 720,970 shares, respectively.

The weighted average fair value per share of stock options granted during fiscal 2013, 2012 and 2011 was $4.85, $11.42 and $8.06, respectively. The fair value of each stock option grant was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:

	Stock Options Granted In Fiscal Year

	2013			2012			2011
Risk-free interest rate		0.6	%		1.5	%		1.8	%
Expected volatility of common stock		51.4	%		46.1	%		47.0	%
Dividend yield		2.3	%		1.1	%		0.0	%
Expected option term in years		5.4			5.7			5.8

The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The expected volatility is based on historical volatility of our common stock, and the expected option term represents the period of time that the stock options granted are expected to be outstanding based on historical exercise trends. The dividend yield represents our anticipated cash dividends at the grant date over the expected option term.

A summary of stock option activity for the three years ended May 31, 2013 follows (shares in thousands):

Restricted Stock

We provide executives and other key employees an opportunity to be awarded performance-based restricted stock. The award is contingent upon the achievement of certain performance objectives, including net income, return on capital, and leverage ratios, or our stock price achieving a certain level over a period of time. During fiscal 2013, 2012 and 2011, we granted 53,280, 362,500, and 269,146 of performance-based restricted shares, respectively.

In addition to the performance-based restricted stock awards, we also granted a total of 48,333 restricted shares to members of the Board of Directors and 65,780 restricted shares to executives and key employees during fiscal 2013.

The fair value of restricted shares is the market value of our common stock on the date of grant. Expense related to all restricted share programs during fiscal 2013, 2012 and 2011 was $7.6 million, $8.4 million and $8.7 million, respectively, recorded in selling, general and administrative expenses.

Restricted share activity during the fiscal year ended May 31, 2013, is as follows (shares in thousands):

			Weighted Average Fair Value on Grant Date

Nonvested at May 31, 2012	1,577		$	22.65
Granted	167		$	12.61

Shareholders' Rights Plan

Pursuant to a shareholder rights plan adopted in 2007, each outstanding share of our common stock carries with it a Right to purchase one share at a price of $140 per share. The Rights become exercisable (and separate from the shares) when certain specified events occur, including the acquisition of 15% or more of the common stock by a person or group (an "Acquiring Person") or the commencement of a tender or exchange offer for 15% or more of the common stock.

In the event that an Acquiring Person acquires 15% or more of the common stock, or if we are the surviving corporation in a merger involving an Acquiring Person or if the Acquiring Person engages in certain types of self-dealing transactions, each Right entitles the holder to purchase for $140 per share (or the then-current exercise price), shares of our common stock having a market value of $280 (or two times the exercise price), subject to certain exceptions. Similarly, if we are acquired in a merger or other business combination or 50% or more of our assets or earning power is sold, each Right entitles the holder to purchase at the then-current exercise price that number of shares of common stock of the surviving corporation having a market value of two times the exercise price. The Rights do not entitle the holder thereof to vote or to receive dividends. The Rights will expire on August 6, 2017, and may be redeemed by us for $.01 per Right under certain circumstances.

5. Income Taxes

The provision for income taxes on pre-tax income includes the following components:

	For the Year Ended May 31,

	2013			2012			2011
Current:
Federal	$	(13.1	)	$	(9.8	)	$	(8.6	)
State		(1.8	)		(0.5	)		1.5
Foreign		12.1			3.0			1.8

		(2.8	)		(7.3	)		(5.3	)
Deferred		29.5			32.8			38.9

	$	26.7		$	25.5		$	33.6

The deferred tax provision results primarily from differences between financial reporting and taxable income arising from depreciation, post-retirement benefits and capitalized program development costs.

Income tax receivable at May 31, 2013 and 2012 was $18.0 million and $22.8 million, respectively, and is included in deposits, prepaids and other on the Consolidated Balance Sheet.

5. Income Taxes (Continued)

The provision for income taxes on pre-tax income differs from the amount computed by applying the U.S. federal statutory income tax rate of 35% for fiscal 2013, 2012 and 2011 to income before taxes, for the following reasons:

	For the Year Ended May 31,

Other		0.2			0.5			0.4

Provision for income taxes	$	26.7		$	25.5		$	33.6

Deferred tax liabilities and assets result primarily from the differences in the timing of the recognition of transactions for financial reporting and income tax purposes and consist of the following components:

5. Income Taxes (Continued)

As of May 31, 2013, we have determined that the realization of our deferred tax assets is more likely than not, and that a valuation allowance is not required based upon our history of operating earnings, our expectations for continued future earnings, the nature of certain of our deferred tax assets and the scheduled reversal of deferred tax liabilities, primarily related to depreciation.

Our fiscal 2013 effective income tax rate was 32.5%, which included a $1.3 million reduction in income tax expense related to the reduction of our state income tax rate from continued implementation of state tax planning strategies. In fiscal 2012, our effective income tax rate was 27.2%, which included a $3.3 million reduction in income tax expense primarily relating to revisions in book versus tax differences, and a $4.0 million reduction in income tax expense, primarily related to the reduction in our state income tax rate from the implementation of state tax planning strategies. Our state tax planning strategies included a new corporate structure and the relocation of one of our significant business units.

Fiscal years 2010 and subsequent are open for examination. Various states and foreign jurisdictions also remain open subject to their applicable statute of limitations. We have no unrecognized tax benefits as of May 31, 2013.

During fiscal 2011, an examination of our fiscal years 2007 through 2009 tax returns was completed, which resulted in a reduction of income tax expense in the amount of $3.5 million, primarily due to the allowance of foreign tax credits which had not previously been benefited.

6. Earnings Per Share

The computation of basic earnings per share is based on the weighted average number of common shares outstanding during each period. The computation of diluted earnings per share is based on the weighted average number of common shares outstanding during the period plus, when their effect is dilutive, incremental shares consisting of shares subject to stock options, shares issuable upon vesting of restricted stock awards and shares to be issued upon conversion of convertible debt.

We use the "if-converted" method in calculating the diluted earnings per share effect of the assumed conversion of our contingently convertible debt issued in fiscal 2006 because the principal for that issuance can be settled in stock, cash or a combination thereof. Under the "if converted" method, the after-tax effect of interest expense related to the convertible securities is added back to net income, and the convertible debt is assumed to have been converted into common shares at the beginning of the period.

In accordance with ASC 260-10-45, Share-Based Payment Arrangements and Participating Securities and the Two-Class Method , our unvested restricted stock awards are deemed participating securities since these shares are entitled to participate in dividends declared on common shares. During periods of net income, the calculation of earnings per share for common stock excludes income attributable to unvested restricted stock awards from the numerator and excludes the dilutive impact of those shares from the denominator. During periods of net loss, no effect is given to the participating securities because they do not share in the losses of the Company.

At May 31, 2013, 2012 and 2011, respectively, options to purchase 872,200 shares, 1,627,000 shares, and 170,000 shares of common stock were outstanding, but were not included in the computation of diluted earnings per share, because the exercise price of these options was greater than the average market price of the common shares for the period then ended.

7. Employee Benefit Plans

Defined Benefit Plans

Prior to January 1, 2000, the pension plan for domestic salaried and non-union hourly employees had a benefit formula based primarily on years of service and compensation. Effective January 1, 2000, we converted our defined benefit plan for substantially all domestic salaried and certain hourly employees to a cash balance pension plan. Under the cash balance pension plan, the retirement benefit is expressed as a dollar amount in an account that grows with annual pay-based credits and interest on the account balance.

7. Employee Benefit Plans (Continued)

The interest crediting rate under our cash balance plan is determined quarterly and is equal to 100% of the average 30-year treasury rate for the second month preceding the applicable quarter published by the Internal Revenue Service. The average interest crediting rate under our cash balance plan for the fiscal year ended May 31, 2013 was 4.5%. Effective June 1, 2005, the existing cash balance plan was frozen and the annual pay-based credits were discontinued. Also effective June 1, 2005, the defined contribution plan was modified to include increased employer contributions and an enhanced profit sharing formula. Defined pension benefits for certain union hourly employees are based primarily on a fixed amount per year of service.

Certain foreign operations of domestic subsidiaries also have a defined benefit pension plan. Benefit formulas are based generally on years of service and compensation. It is the policy of these subsidiaries to fund at least the minimum amounts required by local laws and regulations.

We provide eligible outside directors with benefits upon retirement on or after age 65 provided they have completed at least five years of service as a director. Benefits are paid quarterly in cash equal to 25% of the annual retainer fee payable to active outside directors. Payment of benefits commences upon retirement and continues for a period equal to the total number of years of the retired director's service up to a maximum of ten years, or death, whichever occurs first. In fiscal 2001, we terminated this plan for any new members of the Board of Directors first elected after May 31, 2001. No current directors participate in this plan.

Assumptions

The assumptions used in accounting for our plans are estimates of factors including, among other things, the amount and timing of future benefit payments. The following table presents the key weighted-average assumptions used in the measurement of our projected benefit obligations:

	May 31,

	2013			2012
Discount rate:
Domestic plans		4.3	%		4.1	%
International plans		3.7			4.1
Rate of compensation increase:
Domestic plans		2.5	%		2.5	%
International plans		3.0			3.0

A summary of the weighted-average assumptions used to determine net periodic pension expense is as follows:

	For the Year Ended May 31,

	2013			2012			2011
Discount rate:
Domestic plans		4.1	%		5.3	%		5.6	%
International plans		4.1			5.5			4.5
Rate of compensation increase:
Domestic plans		2.5	%		3.5	%		3.5	%
International plans		3.0			3.0			3.0
Expected long-term rate on plan assets:
Domestic plans		8.0	%		8.0	%		8.0	%
International plans		4.2			5.8			4.5

The discount rate was determined by projecting the expected future benefit payments as defined for the projected benefit obligation, discounting those expected payments using a theoretical zero-coupon spot yield curve derived from a universe of high-quality bonds as of the measurement date, and solving for the single equivalent discount rate that resulted in the same projected benefit obligation.

Plan Assets

The following table sets forth the actual asset allocation and target allocations for our U.S. pension plans:

	May 31,

	May 31,						Target Asset Allocation
	2013			2012			Target Asset Allocation
Equity securities		61	%		59	%		45 - 75	%

		100	%		100	%

The assets of U.S pension plans are invested in compliance with the Employee Retirement Income Security Act of 1974 (ERISA). The investment goals are to provide a total return that, over the long term, optimizes the long-term return on plan assets at an acceptable risk, and to maintain a broad diversification across asset classes and among investment managers. We believe that there are no significant concentrations of risk within our plan assets as of May 31, 2013. Direct investments in our securities and the use of derivatives for the purpose of speculation are not permitted. The assets of the U.S. pension plans are invested primarily in equity and fixed income mutual funds, individual common stocks, and fund-of-funds hedge funds.

The assets of the non-domestic plan are invested in compliance with local laws and regulations and are comprised primarily of equity and fixed income mutual funds.

To develop our expected long-term rate of return assumption on domestic plans, we use long-term historical return information for our targeted asset mix and current market conditions.

The following table sets forth by level, within the fair value hierarchy, pension plan assets at their fair value as of May 31, 2013:

Valuation Techniques Used to Determine Fair Value

Cash equivalents are investments with maturities of three months or less when purchased. The fair values are based on observable market prices and categorized as Level 1.

With respect to individually held equity securities, including investments in U.S. and international securities, the trustees obtain prices from pricing services, whose prices are obtained from direct feeds from market exchanges, which we are able to independently corroborate. Equity securities held individually are primarily traded on exchanges that contain only actively traded securities, due to the volume trading requirements imposed by these exchanges. Equity securities are value based on quoted prices in active markets and are categorized as Level 1.

7. Employee Benefit Plans (Continued)

Equity and fixed income mutual funds are maintained by investment companies that hold certain investments in accordance with a stated set of fund objectives, which are consistent with our overall investment strategy. The values of some of these funds are publicly quoted. For equity and fixed income mutual funds which are publicly quoted, the funds are valued based on quoted prices in active markets and have been categorized as Level 1. For equity and fixed income mutual funds which are not publicly quoted, the fund administrators value the funds using the net asset value per fund share, derived from quoted prices in active markets of the underlying securities. These funds have been categorized as Level 2.

Hedge fund and hedge fund-of-funds investments include those seeking to maximize absolute returns using a broad range of strategies to enhance returns and provide additional diversification. The fair value of hedge funds and hedge fund-of-funds is determined using net asset value or its equivalent subject to certain restrictions, such as a lock-up period. For our investments that have terms that allow redemption within a reasonable period of time from the measurement date, the hedge fund investments are categorized as Level 2. For investments that may limit our ability to redeem the investments at the measurement date or within a reasonable period of time, the hedge fund and hedge fund-of-funds investments are categorized as Level 3.

Future Benefit Payments and Funding

The following table summarizes our estimated future pension payments by fiscal year:

	Fiscal Year

	2014		2015		2016		2017		2018		2019 to 2023
Estimated future pension payments	$	9.7	$	5.5	$	5.6	$	5.4	$	6.2	$	32.3

Our contribution policy for the domestic plans is to contribute annually, at a minimum, an amount which is deductible for federal income tax purposes and that is sufficient to meet actuarially computed pension benefits. We anticipate contributing approximately $7.0 million during fiscal 2014.

Postretirement Benefits Other Than Pensions

We provide health and life insurance benefits for certain eligible retirees. The postretirement plans are unfunded and in fiscal 1995, we completed termination of postretirement health and life insurance benefits attributable to future services of collective bargaining and other domestic employees. The unfunded projected benefit obligation for this plan was $1.0 million and $1.1 million as of May 31, 2013 and 2012, respectively. We have omitted substantially all of the required disclosures related to this plan because the plan is not material to our consolidated financial position or results of operations.

Defined Contribution Plan

The defined contribution plan is a profit sharing plan which is intended to qualify as a 401(k) plan under the Internal Revenue Code. Under the plan, employees may contribute up to 75% of their pretax compensation, subject to applicable regulatory limits. We may make matching contributions up to 5% of compensation as well as discretionary profit sharing contributions. Our contributions vest on a pro-rata basis during the first three years of employment. We also provide profit sharing benefits for certain

executives and key employees to supplement the benefits provided by the defined contribution plan. Expense charged to the statement of income for our matching contributions, including profit sharing contributions, was $14.0 million in fiscal 2013, $13.2 million in fiscal 2012 and $10.5 million in fiscal 2011 for these plans.

8. Acquisitions

On December 2, 2011, we acquired Telair International GmbH ("Telair") and Nordisk Aviation Products, AS ("Nordisk"). Telair is a leader in the design, manufacture and support of cargo loading systems for wide-body and narrow-body aircraft with established positions on the world's most popular current and next-generation passenger and freighter aircraft. Telair operates from facilities in Germany, Sweden and Singapore. Nordisk designs and manufactures heavy duty pallets and lightweight cargo containers for commercial airlines from facilities in Norway and China. The purchase price of the acquisition was $280.0 million paid at closing, plus or minus a working capital adjustment. During the fourth quarter of fiscal 2012, the working capital adjustment was finalized, which increased the purchase price to $296.5 million. The $16.5 million working capital adjustment was paid in the first quarter of fiscal 2013. The units operate as part of our Technology Products segment.

During the second quarter of fiscal 2013, we completed the final purchase price allocation for Telair and Nordisk. We made an adjustment between goodwill and identified intangibles of $11.0 million as part of the final purchase price allocation. Our balance sheet at May 31, 2012 has not been retrospectively adjusted to reflect the adjustment as it is not material. The results of the final purchase price allocation are as follows:


Cash	$	1.5
Accounts receivable		47.1
Inventories		54.5
Prepaid expenses		4.1
Property, plant and equipment		17.0
Deferred tax assets		34.3
Goodwill		103.9
Identified intangibles		120.0
Notes payable		(1.6	)
Accounts payable		(14.7	)
Deferred tax liabilities		(34.3	)
Accrued liabilities		(27.5	)
Other long-term liabilities		(7.8	)

On October 11, 2011, we acquired Airinmar Holdings Limited ("Airinmar"), a sophisticated repair, outsourcing and warranty claim manager. Airinmar operates as part of our Aviation Services segment. Total consideration was estimated to be $43.5 million, which included $23.2 million cash paid at closing, and a potential earn-out payment of $20.3 million. The potential earn-out payment was to be based upon Airinmar achieving certain EBITDA (earnings before interest, taxes, depreciation and amortization) levels over a two-year period, as well as retaining certain key customers. A liability of $20.3 million was recognized as an estimate of the acquisition date fair value of the earn-out and was included in Other

liabilities and deferred income on our Consolidated Balance Sheet. During the fourth quarter of 2012, this estimate was reduced by $3.4 million and this change in the fair value of the earn-out was recognized in earnings. During the third quarter of fiscal 2013, we agreed with Airinmar to a $4.6 million final settlement for the earn-out. The $9.0 million change in the fair value of the earn-out liability was recognized in earnings.

During the first quarter of fiscal 2013, we completed the final purchase price allocation for Airinmar and the results are as follows:


Cash	$	3.7
Accounts receivable		8.0
Prepaid expenses		0.9
Property, plant and equipment		0.6

9. Aircraft Portfolio

Within our Aviation Services segment, we own commercial aircraft with joint venture partners as well as aircraft that are wholly-owned. These aircraft are available for lease or sale to commercial air carriers.

Aircraft Owned through Joint Ventures

As of May 31, 2013 and 2012, we had ownership interests in four and 18 aircraft, respectively, with joint venture partners. As of May 31, 2013 and 2012, our equity investment in the aircraft owned with joint venture partners was approximately $27.5 million and $41.3 million, respectively, and is included in Investment in joint ventures on the Consolidated Balance Sheet. Included in the May 31, 2013 amount is notes receivable in the amount of $15.3 million for aircraft which the joint ventures have sold. Our aircraft joint ventures represent investments in limited liability companies that are accounted for under the equity method of accounting. Our membership interest in each of these limited liability companies is 50%, and the primary business of these companies is the acquisition, ownership, lease and disposition of certain commercial aircraft. Aircraft were purchased with cash contributions by the members of the companies and debt financing provided to the limited liability companies on a limited recourse basis. Under the terms of servicing agreements with certain of the limited liability companies, we provide administrative services and technical advisory services, including aircraft evaluations, oversight and logistical support of the maintenance process and records management. We also provide remarketing services with respect to the divestiture of aircraft by the limited liability companies. During fiscal 2013, 2012 and 2011, we were paid $0.5 million, $0.6 million and $1.3 million, respectively, for such services. The income tax benefit or expense related to the operations of the ventures is recorded by the member companies.

Distributions from joint ventures are classified as operating or investing activities in the Consolidated Statements of Cash Flows based upon an evaluation of the specific facts and circumstances of each distribution.

10. Equipment on Long-Term Lease

In fiscal 2005, we entered into a series of ten-year agreements with a regional airline to provide supply chain services for its fleet of CRJ 700/900, ERJ 145 and CRJ 200 regional jets. As part of the agreements, we purchased from the customer approximately $58.4 million of equipment to support the program. The equipment is included in equipment on long-term lease on the Consolidated Balance Sheet and is being depreciated on a straight-line basis over its estimated useful life. The net book value of this equipment was $28.1 million and $30.9 million at May 31, 2013 and 2012, respectively.

11. Commitments and Contingencies

On October 3, 2003, we entered into a sale-leaseback transaction whereby we sold and leased back a facility located in Garden City, New York. The lease is classified as an operating lease. Net proceeds from the sale of the facility were $14.0 million and the cost and related accumulated depreciation of the facility of $9.5 million and $4.6 million, respectively, were removed from the Consolidated Balance Sheet at the time of sale. The gain realized on the sale of $9.1 million has been deferred and is being amortized over the 20-year lease term. The unamortized balance of the deferred gain as of May 31, 2013 is $4.8 million and is included in Other liabilities and deferred income on the Consolidated Balance Sheet.

In addition to the Garden City lease, we lease other facilities and equipment under agreements that are classified as operating leases that expire at various dates through 2034. Future minimum payments under all operating leases at May 31, 2013 are as follows:

Year	Facilities and Equipment

2014	$	31.4
2015		21.1
2016		13.5
2017		10.8
2018		8.5
2019 and thereafter		41.7

Rental expense for facilities and equipment during fiscal years 2013, 2012 and 2011 was $35.2 million, $30.3 million and $27.9 million, respectively.

We enter into purchase obligations which arise in the ordinary course of business and represent a binding commitment to acquire inventory, including raw materials, parts and components, as well as equipment to support the operations of our business. The aggregate amount of purchase obligations due in each of the next five fiscal years is $270.4 million in 2014, $8.8 million in 2015, $0.1 million in 2016 and $0 in 2017 and 2018.

11. Commitments and Contingencies (Continued)

We routinely issue letters of credit and performance bonds in the ordinary course of our business. These instruments are typically issued in conjunction with insurance contracts or other business requirements. The total of these instruments outstanding at May 31, 2013 was approximately $17.8 million.

We are involved in various claims and legal actions, including environmental matters, arising in the ordinary course of business (see Item 3 Legal Proceedings). In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on our consolidated financial condition or results of operations.

12. Restructuring and Impairment Charges

In order to improve efficiencies and streamline operations in the Technology Products segment, during fiscal 2012 we decided to close two manufacturing plants and idle one other facility. The financial impact included restructuring and other charges of $3.7 million. Approximately $1.2 million was recorded as severance expense and approximately $2.5 million was recorded for asset impairments to reduce the carrying value of certain equipment and inventory to net realizable value. The charges are recorded in Costs of sales—restructuring and impairment in the Consolidated Statement of Income.

During fiscal 2011, we decided to offer one narrow body aircraft for sale from our wholly-owned aircraft portfolio and subsequent to May 31, 2011, we entered into a letter of intent to sell the aircraft to a foreign air carrier. As a result, we recorded a $5.3 million pre-tax impairment charge in fiscal 2011 to reduce the carrying value of the aircraft to its net realizable value, which was approximately $8.9 million at May 31, 2011.

13. Gain on Sale of Product Line

During fiscal 2011, we sold substantially all of the assets of a non-strategic product line within our Aviation Services segment. Proceeds from the sale were $10.0 million cash paid at closing, and the net carrying value of the assets sold was $4.1 million, resulting in a pre-tax gain on sale of product line of $5.9 million. The gain on this transaction has been classified as a component of operating income.

14. Other Noncurrent Assets

License Fees

In June 2011, we entered into a ten-year agreement with Unison Industries to be the exclusive worldwide aftermarket distributor for Unison's electrical components, sensors, switches and other systems for aircraft and industrial uses. The agreement is expected to generate approximately $600.0 million in revenues for us over its ten-year term. In connection with the agreement, we agreed to pay Unison Industries $20.0 million for the exclusive distribution rights with $7.0 million paid in June 2011, and $1.3 million payable by January 31 of each calendar year beginning in January 2012 through 2021.

As of May 31, 2013 and 2012, the unamortized balance of the license is $13.5 million and $15.1 million, respectively, and is being amortized over a ten-year period. The current portion of the deferred payments of $1.2 million is recorded in Accrued liabilities and the long-term portion of $6.9 million is included in Other liabilities and deferred income on the Consolidated Balance Sheet.

Segment Reporting

Prior to the second quarter of fiscal year 2013, we reported our activities in four business segments: Aviation Supply Chain; Government and Defense Services; Maintenance, Repair and Overhaul; and Structures and Systems. During the second quarter, we changed our segment presentation to reflect the way our Chief Executive Officer now evaluates performance and the way we are organized internally. We now report our activities in two business segments: Aviation Services and Technology Products. The new Aviation Services segment includes our former Aviation Supply Chain and Maintenance, Repair and Overhaul segments and most of the former Government and Defense Services segment, and the new Technology Products segment represents our former Structures and Systems business segment and our small shelter integration unit, which previously was part of the Government and Defense Services segment. We have recast all prior periods presented to conform to the new segment presentation.

16. Business Segment Information (Continued)

Sales in the Aviation Services segment are derived from the sale and lease of a wide variety of new, overhauled and repaired engine and airframe parts and components to the commercial aviation and government and defense markets. We provide customized inventory supply chain management, performance based logistics programs, aircraft component repair management services, and aircraft modifications. The segment also includes repair, maintenance and overhaul of aircraft and landing gear and expeditionary airlift services. Cost of sales consists principally of the cost of product, direct labor, overhead, and aircraft maintenance costs.

Sales in the Technology Products segment are derived from the engineering, designing and manufacturing of containers, pallets and shelters used to support the U.S. military's requirements for a mobile and agile force and system integration services for specialized command and control systems. The segment also manufactures heavy-duty pallets and lightweight cargo containers for the commercial market, in-plane cargo loading and handling systems for commercial and military applications, and steel and composite machined and fabricated parts, components and sub-systems for various aerospace and defense programs. Cost of sales consists principally of the cost of material to manufacture products, direct labor and overhead.

The accounting policies for the segments are the same as those described in Note 1. Our chief operating decision making officer (Chief Executive Officer) evaluates performance based on the reportable segments and utilizes gross profit as a primary profitability measure. The assets and certain expenses related to corporate activities are not allocated to the segments. Our reportable segments are aligned principally around differences in products and services.

Gross profit is calculated by subtracting cost of sales from sales. Selected financial information for each segment is as follows:

ITEM 9A. CONTROLS AND PROCEDURES

As required by Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of May 31, 2013. This evaluation was carried out under the supervision and with participation of our Chief Executive Officer and Chief Financial Officer. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures. Therefore, effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective as of May 31, 2013, ensuring that information required to be disclosed in the reports that are filed under the Act is recorded, processed, summarized and reported in a timely manner.

There were no changes in our internal control over financial reporting during the three-month period ended May 31, 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

MANAGEMENT REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of AAR CORP. is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Act. The Company's internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with U.S. generally accepted accounting principles. Internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems which are determined to be effective provide only reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of its internal control over financial reporting based on criteria for effective internal control over financial reporting described in the Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992).

Based on our assessment, management concluded that the Company maintained effective internal control over financial reporting as of May 31, 2013.

KPMG LLP, our independent registered public accounting firm, has issued a report on the effectiveness of our internal control over financial reporting. That report appears below.

Report of Independent Registered Public Accounting Firm

TO THE STOCKHOLDERS AND BOARD OF DIRECTORS OF AAR CORP.:

We have audited AAR CORP. and subsidiaries' (the Company) internal control over financial reporting as of May 31, 2013, based on criteria established in the 1992 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management Report On Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

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

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

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

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of May 31, 2013, based on criteria established in the 1992 Internal Control—Integrated Framework issued by the COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of the Company as of May 31, 2013 and 2012, and the related consolidated statements of income, comprehensive income, changes in equity, and cash flows for each of the years in the three-year period ended May 31, 2013, and our report dated July 25, 2013 expressed an unqualified opinion on those consolidated financial statements.

[FORM OF REVERSE SIDE OF NOTE]

1.75% Convertible Senior Notes Due 2015

1. Interest

AAR CORP., a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Note at the rate per annum shown above. The Company will pay interest semiannually on February 1 and August 1 of each year. Interest on the Notes will accrue from the most recent date to which interest has been paid on the Notes or, if no interest has been paid, from February 14, 2013. The Company shall, to the fullest extent permitted by law, pay interest on overdue principal and overdue installments of interest, if any (plus interest on such interest to the extent lawful), at the rate borne by the Notes, which interest shall be payable upon demand. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment

By no later than 11:00 a.m. (New York City time) on the date on which any principal of or interest on any Note is due and payable, the Company shall irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay such principal and/or interest. The Company will pay interest (except Defaulted Interest) on the principal amount of the Notes on each February 1 and August 1 to the Persons who are registered Holders of Notes at the close of business on the January 15 and July 15 next preceding the Interest Payment Date even if Notes are canceled or repurchased after the Record Date and on or before the Interest Payment Date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. The Company will make all payments in respect of a Definitive Note (including principal and interest) in U.S. dollars at the office of the Trustee. At the Company’s option, however, the Company may make such payments by mailing a check to the registered address of each Holder thereof as such address shall appear on the Note Register or, with respect to Notes represented by a Global Note, by wire transfer of immediately available funds to the accounts specified by the Depositary.

3. Paying Agent, Conversion Agent and Registrar

Initially, U.S. Bank National Association (“Trustee”) will act as Paying Agent, Conversion Agent and Registrar. The Company may appoint and change any Paying Agent, Conversion Agent, Registrar or co-registrar without notice to any Holder. The Company or any of its domestically incorporated Subsidiaries may act as Paying Agent, Conversion Agent, Registrar or co-registrar.

4. Indenture

The Company issued the Notes under an Indenture dated as of February 14, 2013 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”), among the Company and the Trustee. The terms of the Notes include those stated

in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect from time to time (the “Act”). Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture and the Act for a statement of those terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

The Notes are senior unsecured obligations of the Company limited to $30,000,000 aggregate principal amount.

5. Redemption at the Option of the Company

No sinking fund is provided for the Notes. The Notes are redeemable for cash in whole, or in part, at any time (i) from the date of issuance to February 1, 2014 in the event of a Change of Control and (ii) from February 1, 2014 to February 1, 2015 (regardless of whether a Change of Control has occurred). In each case, the redemption shall be at the option of the Company and the redemption price (the “Redemption Price”) shall be computed to result in a yield of 3.75% from the date of issuance to the date immediately prior to the Redemption Date (which 3.75% yield shall include interest paid, and accrued but unpaid, as of the date immediately prior the Redemption Date) such that the Redemption Price (inclusive of paid, and accrued but unpaid, interest) shall be 101.945% of the principal of the Note if the Redemption Date is February 1, 2014 and 104.038% of the principal of the Note if the Redemption Date is February 1, 2015.

6. Notice of Redemption at the Option of the Company

Notice of redemption at the option of the Company shall be mailed at least 30 days but not more than 60 days before a Redemption Date to the Trustee, the Paying Agent and each Holder of Notes to be redeemed at the Holder’s registered address. If money sufficient to pay the Redemption Price of all Notes (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent prior to or on the Redemption Date, on and after the Redemption Date, interest, if any, shall cease to accrue on such Notes or portions thereof. Notes in denominations larger than $1,000 principal amount may be redeemed in part but only in integral multiples of $1,000 principal amount.

7. Purchase by the Company at the Option of the Holder Upon a Designated Event

If a Designated Event shall occur, each Holder shall have the right, at such Holder’s option and subject to the terms and conditions of the Indenture, to require the Company to purchase any or all of such Holder’s Notes or any portion of the principal amount thereof that is equal to $1,000 or an integral multiple of $1,000 on the day that is 45 days after the date of the Company Notice of the occurrence of the Designated Event (subject to extension to comply with applicable law) for a Designated Event Purchase Price equal to 100% of the principal amount of Notes purchased plus accrued and unpaid interest to but not including the Designated Event Purchase Date, which Designated Event Purchase Price shall be paid in cash.

Holders have the right to withdraw any Designated Event Purchase Notice, as the case may be, by delivery to the Paying Agent of a written notice of withdrawal in accordance with the provisions of the Indenture.

8. Conversion

Subject to the procedures set forth in the Indenture, a Holder may convert Notes on or before the close of business on January 31, 2015 during the periods and upon satisfaction of the conditions set forth in the Indenture.

Notes in respect of which a Holder has delivered a notice of exercise of the option to require the Company to purchase such Notes pursuant to Article VI of the Indenture may be converted only if the notice of exercise is withdrawn in accordance with the terms of the Indenture.

The initial Conversion Rate is 35.0777 shares of Common Stock per $1,000 Note. A Holder may convert a portion of the principal amount of Notes if the portion is $1,000 or a multiple of $1,000, subject to adjustment in certain events described in the Indenture. Upon conversion of the Notes, the Company shall deliver the amount of cash and the number of shares of Common Stock, if any, determined pursuant to Section 9.18 of the Indenture.

To convert the Notes a Holder must (1) complete and manually sign the irrevocable conversion notice on the back of the Notes (or complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent at the office maintained by the Conversion Agent for such purpose, (2) surrender the Notes to the Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Conversion Agent, the Company or the Trustee and (4) pay any transfer or similar tax, if required.

9. Denominations; Transfer; Exchange

The Notes are in registered form without coupons in denominations of principal amount of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Notes (A) for a period beginning at the opening of business 15 days before any selection of Notes for redemption or repurchase and ending at the close of business on the day notice of such redemption or repurchase is deemed to have been given to all Holders of Notes to be so redeemed or repurchased or (B) selected for redemption or repurchase in whole or in part, except for the transfer of the unredeemed portion of any Note being redeemed in part.

10. Persons Deemed Owners

The registered Holder of this Note may be treated as the owner of this Note for all purposes.

11. Unclaimed Money

If money for the payment of the principal of, or interest on the Note remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its written request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment.

12. Amendment, Waiver

Subject to certain exceptions set forth in the Indenture, (i) the Indenture and the Notes may be amended with the written consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes) and (ii) any default (other than with respect to nonpayment) or noncompliance with any provision may be waived with the written consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes). Subject to certain exceptions set forth in the Indenture, without the consent of any Holder, the Company and the Trustee may amend the Indenture or the Notes.

13. Defaulted Interest

Except as otherwise specified with respect to the Notes, any Defaulted Interest on any Note shall forthwith cease to be payable to the registered Holder thereof on the relevant Record Date or accrual date, as the case may be, by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company as provided for in Section 2.11 of the Indenture.

14. No Recourse Against Others

No recourse for the payment of the principal of or interest on this Note and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture, this Note or in any supplemental indenture, or because of the creation of any Indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer, director, or subsidiary, past, present or future, of the Company or of any successor corporation or entity, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, it being understood that all such liability is hereby waived and released as a condition to, and as a consideration for, the execution and delivery of the Indenture and the issue of this Note.

15. Authentication

This Note shall not be valid until an authorized signatory of the Trustee (or an authenticating agent acting on its behalf) manually signs the certificate of authentication on the other side of this Note.

16. Abbreviations

Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entirety), JT TEN (=joint tenants

(“Agreement”)

Subject to the provisions set forth herein and the terms and conditions of the AAR CORP. Stock Benefit Plan and the Long-Term Incentive Plan for Fiscal 2013 (together, the “Plan”), the terms of which are hereby incorporated by reference, and in consideration of the agreements of the Grantee herein provided, AAR CORP., a Delaware corporation (“Company”), hereby grants to the Grantee an option, effective July 15, 2013 (“Date of Grant”) entitling the Grantee to purchase from the Company common stock of the Company, par value $1.00 per share (“Common Stock”), in the number of shares and at the purchase price per share, and on the schedule, set forth in the Company’s notification of option grant letter to the Grantee and incorporated herein by reference (“Option”), subject to the terms and conditions set forth herein:

1. Acceptance by Grantee . The exercise of the Option is conditioned upon the acceptance by the Grantee of the terms and conditions of the Option as set forth in this Agreement. The Grantee must confirm acceptance of the Option and this Agreement on Morgan Stanley’s web site (www.benefitaccess.com). If the Grantee does not accept the Option and this Agreement within 30 days from the date of the notification of the Option, the Option grant referenced herein shall expire unless the acceptance date is extended in writing signed by the Company.

2. Termination of Employment .

(a) In General . If the Grantee’s employment with the Company and all subsidiaries of the Company is terminated for any reason other than for Retirement, death, Disability or Cause, the unvested portion of the Grantee’s Option shall expire on the date of such termination of employment and the vested portion of the Grantee’s Option shall continue to be exercisable until the earlier of (i) three months after such termination of employment or (ii) the date the Option expires in accordance with its terms.

(b) Retirement . If the Grantee’s employment with the Company and all subsidiaries of the Company is terminated by reason of Retirement, the Option shall continue to vest and become exercisable in accordance with its terms and may be exercised by the retired Grantee in the same manner and to the same extent as if the Grantee had continued employment during that period; provided, however, that (i) if the Grantee dies within three months following Retirement but before the Option expires, paragraph 2(c)(ii) shall apply and (ii) if the Grantee dies later than three months following Retirement but before the Option expires, the then unvested portion of the Option shall expire on the date of such death and the vested portion of the Option shall continue to be exercisable by the Grantee’s Successor until the date that the Option expires by its terms. For this purpose, “Retirement” means the Grantee’s voluntary termination of employment, or his termination of employment by the Company or a subsidiary without Cause, when he has (i) attained age 65 or (ii) attained age 55 and his age plus the number of his consecutive years of service with the Company and subsidiaries is at least 75.

(c) Death . If (i) the Grantee’s employment with the Company and all subsidiaries of the Company is terminated by reason of death or (ii) the Grantee dies within three months after the termination of employment with the Company and all subsidiaries for reasons other than Cause, the unvested portion of the Option shall expire on the date of such death and the vested portion of the Option shall continue to be exercisable until the earlier of (i) one year after the Grantee’s death or (ii) the date the Option expires in accordance with its terms.

(d) Disability . If the Grantee’s employment with the Company and all subsidiaries is terminated by reason of Disability, the Option shall continue to vest and become exercisable until the earlier of (i) one year after such termination of employment or (ii) the date the Option expires in accordance with its terms, and during such period the Option may be exercised by the disabled Grantee; provided, however, that if the Grantee dies after termination of employment but prior to the date the Option expires, the unvested portion of the Option shall expire on the date of such death and the vested portion of the Option shall continue to be exercisable as described herein. For this purpose, “Disability” means the inability of the Grantee to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months.

(e) Cause . If the Grantee’s employment is terminated by the Company or any subsidiary of the Company for Cause, the Option shall expire immediately upon such termination of employment and no portion of the Option shall be exercisable thereafter. For this purpose, “Cause” means (i) the Grantee’s dishonesty, fraud or breach of trust, gross negligence or substantial misconduct in the performance of, or substantial nonperformance of, his assigned duties or willful violation of Company policy, (ii) any act or omission by the Grantee that is a substantial cause for a regulatory body with jurisdiction over the Company to request or recommend the suspension or removal of the participant or to impose sanctions upon the Company or the Grantee, or (iii) a material breach by the Grantee of any applicable employment agreement between him and the Company. The Company shall have the sole discretion to determine whether a Grantee’s termination of employment is for Cause.

(f) Restrictive Covenant . If at any time prior to the expiration of the Option, the Grantee, without the Company’s express written consent, directly or indirectly, alone or as a member of a partnership, group or joint stock venture or as an employee, officer, director, or greater than 1% stockholder of any corporation, or in any capacity engages in any activity which is competitive with any of the businesses conducted by the Company or its affiliated companies any time during the Grantee’s term of employment, (i) the Option shall immediately expire and become unexercisable, (ii) the Grantee shall forfeit and return all shares of Common Stock acquired and then held by the Grantee pursuant to the exercise of any portion of this Option, and (iii) the Grantee shall immediately pay to the Company an amount equal to the appreciation realized on any shares of Common Stock acquired and sold or otherwise disposed of in connection with the exercise of this Option, as of the date sold.

3. Change in Control . In the event a Change in Control occurs, whether or not such Change in Control has the prior written approval of a majority of the Continuing Directors, and notwithstanding any conditions or restrictions contained in this Agreement, the

outstanding Option shall become immediately exercisable on the date of such Change in Control with respect to all shares of Common Stock covered thereby, whether vested or not and shall remain exercisable until the Option expires.

4. Change in Outstanding Shares . Any increase or decrease in the number of outstanding shares of Common Stock of the Company occurring through stock splits, stock dividends, stock consolidations, spin-offs, other distributions of assets to stockholders or assumption or conversion of outstanding Options due to an acquisition after the Date of Grant of the Option shall be reflected proportionately in the number of shares of Common Stock subject to the Option, and a proportionate reduction or increase, as applicable, shall be made in the Option Price Per Share hereunder. Any fractional shares resulting from such adjustment shall be eliminated. If changes in capitalization other than those considered above shall occur, the Board shall make such adjustment in the number or class of shares purchasable upon exercise of the Option and in the Option Price Per Share as the Board in its discretion may consider appropriate, and all such adjustments shall be conclusive upon all persons.

5. Exercise of Option . Notice of an election to exercise any portion of the Option, specifying the portion thereof being exercised and the exercise date, shall be given by the Grantee, or the Grantee’s personal representative in the event of the Grantee’s death or Disability necessitating a Court approved personal representative, by notifying Morgan Stanley pursuant to the on-line exercise procedures set forth on the AAR Stock Benefit Plan online exercise web site (www.benefitaccess.com).

6. Payment of Exercise Price and Withholding . Upon any exercise of the Option, an amount necessary to pay the exercise price and to satisfy applicable tax withholding requirements, including those arising under federal, state and local income tax laws, will be due and payable at the time of exercise prior to the issuance of any shares of Common Stock pursuant to such exercise. The Grantee may pay the exercise price and satisfy the minimum withholding requirements by one or more of the following methods: (a) in cash, (b) in cash received from a broker-dealer to whom the Grantee has submitted an exercise notice and irrevocable instructions to deliver the purchase price and amount of tax withholding to the Company from the proceeds of the sale of shares of Common Stock subject to the Option, (c) by delivery to the Company of other Common Stock owned by the Grantee that is acceptable to the Company, valued at its fair market value on the date of exercise, (d) by certifying to ownership by attestation of such previously owned Common Stock, or (e) by having shares withheld from the Common Stock otherwise distributable to the Grantee upon exercise of the Option. A Grantee’s election pursuant to the preceding sentence must be made at the time of exercise of such Option and must be irrevocable. Payment shall be made pursuant to the online procedures set forth on the AAR Stock Benefit Plan online website through Morgan Stanley (www.benefitaccess.com).

7. Option Not Transferable . The Option may be exercised only by the Grantee during the Grantee’s lifetime and may not be transferred other than by will, the applicable laws of descent or distribution, or an assignment subject to and meeting the requirements of the Plan and made in accordance with Company procedures in effect from time to time for approval by the Company and consummation of the assignment (copies of procedures

and forms are available from the Corporate Secretary upon request). The Option shall not otherwise be transferred, assigned, pledged or hypothecated for any purpose whatsoever and is not subject, in whole or in part, to execution, attachment, or similar process. Any attempted assignment, transfer, pledge or hypothecation or other disposition of the Option, other than in accordance with the terms set forth herein, shall be void and of no effect.

8. No Rights as a Stockholder . Neither the Grantee nor any other person entitled to exercise the Option under the terms hereof shall be, or have any of the rights or privileges of, a stockholder of the Company in respect of any of the shares of Common Stock issuable on exercise of the Option, unless and until such shares shall have been actually issued.

9. Recoupment . Notwithstanding any other provision of this Agreement, to the extent required by applicable law, including the Dodd-Frank Wall Street Reform and Consumer Protection Act, or pursuant to the Company’s policy as may be in effect, the Company shall have the right to seek recoupment of all or any portion of an Option (including by forfeiture of the then outstanding and unexercised portion of the Option (whether vested or unvested) or by the Grantee’s remittance to the Company of Common Stock acquired on exercise of the Option or of a cash payment for the value thereof). The value with respect to which such recoupment is sought shall be determined by the Company. The Company shall be entitled, as permitted by applicable law, to deduct the amount of such payment from any amounts the Company may owe to the Grantee.

10. Miscellaneous .

(a) In the event the Option shall be exercised in whole or in part, the number of Shares of Common Stock subject to the Option shall be reduced accordingly.

(b) When the Option expires, such expiration shall occur at the Company’s close of business on the date of expiration.

(c) The Option shall be exercised only in accordance with such Company administrative procedures as may be in effect from time to time.

(d) The Option and this Agreement shall be construed, administered and governed in all respects under and by the laws of the State of Illinois.

(e) Capitalized terms used herein and not defined herein will have the meanings set forth in the Plan or the notification of grant letter.

(f) Nothing in the Option shall confer on the Grantee any right to be or to continue in the employ of the Company or any of its subsidiaries or shall interfere in any way with the right of the Company or any of its subsidiaries to terminate the employment of the Grantee at any time for any reason or no reason.

(g) This Agreement has been examined by the parties hereto, and accordingly the rule of construction that ambiguities be construed against a party which causes a document to be drafted shall have no application in the construction or interpretation hereof. If

any part of this Agreement is held invalid for any reason, the remainder hereof shall nevertheless remain in full force and effect.

(h) This Agreement constitutes the entire agreement between the parties concerning the subject matter hereof and any prior understanding or representation of any kind antedating this Agreement concerning such subject matter shall not be binding upon either party except to the extent incorporated herein; provided, however, that this Agreement, including paragraph 2, shall be subject to the provisions of any written employment or severance agreement that has been or may be executed by the Grantee and the Company, and the provisions in such employment or severance agreement concerning the Option shall supercede any inconsistent or contrary provision of this Agreement. No consent, waiver, modification or amendment hereof, or additional obligation assumed by either party in connection herewith, shall be binding unless evidenced by a writing signed by both parties and referring specifically hereto. No consent, waiver, modification or amendment with respect hereto shall be construed as applicable to any past or future events other than the one in respect of which it was specifically made.

(i) This Agreement shall be construed consistent with the provisions of the Plan and in the event of any conflict between the terms of this Agreement and the terms of the Plan, the terms of the Plan shall control and any terms of this Agreement which conflict with Plan terms shall be void.

Questions concerning the provisions of this Agreement should be directed to the Company’s General Counsel: 630/227-2050; fax 630/227-2059.

any terms and conditions of this Award or any provision of this Agreement or the Plan to issue or release the Award Shares in violation of the Securities Act of 1933 or the law of any government having jurisdiction thereof.

5. Change in Outstanding Shares . In the event of any change in the outstanding shares of Common Stock occurring through stock splits, stock dividends, stock consolidations, spin-offs, other distributions of assets to stockholders or assumption or conversion of outstanding Awards due to an acquisition after the Date of Award, the Award Shares shall be treated in the same manner in any such transaction as other shares of Common Stock. Any additional shares of Common Stock received by the Grantee with respect to the Award Shares in any such transaction shall be subject to the same restrictions as are then applicable to those Award Shares for which the additional shares have been issued.

7. Shares . In aid of the restrictions set forth in paragraph 2, the Grantee will be required to execute a stock power in favor of the Company which will be cancelled upon release of restrictions with respect to Award Shares released. Award Shares shall be held by the Company in electronic book entry form on the records of the Company’s Transfer Agent, together with the executed stock power, for the account of the Grantee until such restrictions are

Any such postponement shall not shorten the term of any restriction attached to the Award Shares and neither the Company nor its directors or officers shall have any obligation or liability to the Grantee or to any other person as to which issuance under the Award Shares was delayed.
