PART I

ITEM 1. BUSINESS
(Dollars in thousands)

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 defense industries. We conduct our business activities primarily through six principal operating subsidiaries: AAR Parts Trading, Inc., AAR Aircraft & Engine Sales & Leasing, Inc., AAR Services, Inc., AAR Aircraft Services, Inc., AAR Manufacturing, Inc., and AAR International, Inc. Our international business activities are conducted primarily through AAR International, Inc.

We report our activities in four business segments: (i) Aviation Supply Chain, comprised primarily of business activities conducted through AAR Parts Trading, Inc., AAR Services, Inc., AAR Allen Services, Inc., (a wholly-owned subsidiary of AAR Parts Trading, Inc. and AAR Services, Inc.), and AAR International, Inc. (ii) Maintenance, Repair and Overhaul, comprised primarily of business activities conducted through AAR Services, Inc., AAR Allen Services, Inc. and AAR Aircraft Services, Inc. (iii) Structures and Systems, comprised primarily of business activities conducted through AAR Manufacturing, Inc., and (iv) Aircraft Sales and Leasing, comprised of business activities primarily conducted through AAR Aircraft & Engine Sales & Leasing, Inc.

Aviation Supply Chain

Activities in our Aviation Supply Chain segment include the purchase and sale of a wide variety of new, overhauled and repaired engine and airframe parts and components for our airline and defense customers. We also repair and overhaul a wide variety of avionics, electrical, electronic, fuel, hydraulic and pneumatic components and instruments and a broad range of internal airframe components for the same customer categories. We provide customized inventory supply and management programs and performance-based logistics programs for engine and airframe parts and components in support of airline and defense customer's maintenance activities. The types of services provided under these programs include program and warehouse management, parts replenishment and parts and component repair and overhaul. We are an authorized distributor for more than 125 leading aviation product manufacturers. In addition, we sell and lease commercial jet engines. We acquire aviation parts and components for the Aviation Supply Chain segment from domestic and foreign airlines, original equipment manufacturers, independent aviation service companies and aircraft leasing companies. From time-to-time, we also purchase aircraft and engines for disassembly to individual parts and components. These assets may be leased to airlines on a short-term basis prior to disassembly. In the Aviation Supply Chain segment, the majority of our sales are made pursuant to standard commercial purchase orders. In certain inventory supply and management programs and performance-based logistics programs, we supply products and services under agreements reflecting negotiated terms and conditions.

Maintenance, Repair and Overhaul

Activities in our Maintenance, Repair and Overhaul segment include airframe maintenance services and the repair and overhaul of most types of landing gear for our airline and defense customers. We have a long-term lease to occupy a portion of an airframe maintenance facility in Indianapolis, Indiana (the "Indianapolis Maintenance Center" or "IMC"), which is owned by the Indianapolis Airport Authority ("IAA"). We believe the IMC is one of the most efficient and state-of-the-art airframe maintenance facilities in the United States. The IMC is comprised of 12 airframe maintenance bays, backshop space to support airframe maintenance activities, warehouse and office space. Our lease with the IAA allows us to occupy up to ten of the maintenance bays and certain office space and expires in December 2014, with a

ten-year renewal option. The lease agreement contains early termination rights for AAR and the IAA, which may be exercised in specified circumstances. We also operate an aircraft maintenance facility located in Oklahoma City, Oklahoma providing airframe maintenance, modification, special equipment installation, painting services and aircraft terminal services for various models of commercial, defense, regional, business and general aviation aircraft. On March 5, 2008, we acquired Avborne Heavy Maintenance, Inc. ("Avborne") and a related entity. Avborne is an independent provider of aircraft heavy maintenance checks, modifications, installations and painting services to commercial airlines, international cargo carriers and major aircraft leasing companies. Avborne performs heavy maintenance on Boeing and Airbus aircraft at a 226,000 square foot leased facility, located at Miami International Airport. The purchase price was approximately $40,000 and included a cash payment of $15,000 and the assumption of a $25,000 industrial revenue bond. On January 12, 2007, we acquired substantially all the assets of Reebaire Aircraft, Inc. ("Reebaire"), a regional airframe maintenance and repair overhaul facility located in Hot Springs, Arkansas. This acquisition increased our regional MRO capacity in North America. In addition to our airframe maintenance facilities we operate a landing gear repair center in Miami, Florida and an aircraft storage facility in Roswell, New Mexico. In this segment, we purchase replacement parts from original equipment manufacturers and suppliers that are used in our maintenance, repair and overhaul operations. We have ongoing arrangements with original equipment manufacturers (OEMs) that provide us access to parts, repair manuals and service bulletins in support of parts manufactured by the OEM. Although the terms of each arrangement vary, they typically are made on standard OEM terms as to duration, price and delivery. When possible, we obtain replacement parts used in repair and overhaul activities from operating units in our Aviation Supply Chain segment.

Structures and Systems

Activities in our Structures and Systems segment include the design, manufacture and repair of pallets and a wide variety of containers and shelters in support of military and humanitarian tactical deployment activities. We design, manufacture and install in-plane cargo loading and handling systems for commercial and military aircraft and helicopters. We also design and manufacture advanced composite materials for commercial, business and military aircraft as well as advanced composite structures for the transportation industry. On December 3, 2007, we acquired Summa Technology, Inc. ("Summa"), a leading provider of high-end sub-systems and precision machining, fabrication, welding and engineering services. The purchase price was approximately $71,000 and was paid in cash. On April 2, 2007, we acquired Brown International Corporation ("Brown"), a privately held defense contractor that provides engineering, design, manufacturing and systems integration services. During the fiscal year ended May 31, 2007 ("fiscal 2007"), we decided to exit our non-core industrial turbine business located in Frankfort, New York, and treat it as a discontinued operation. In this segment, sales are made to customers pursuant to standard commercial purchase orders and contracts. We purchase the raw materials for this business, including aluminum sheets, extrusions and castings and other necessary supplies, from a number of vendors.

Aircraft Sales and Leasing

Activities in our Aircraft Sales and Leasing segment include the sale or 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. Leases have fixed terms; early termination by either party is not permitted except in the event of a breach. In this segment, we purchase aircraft from airlines and aircraft leasing companies for our own account or in partnership with strategic or financial partners typically under joint venture agreements. During the first half of the fiscal year ended May 31, 2008 ("fiscal 2008"), we purchased 20 aircraft with joint venture partners. We have not purchased any aircraft since November 2007 in this segment. At May 31, 2008, the total number of aircraft held in these joint ventures was 29. We also own eight aircraft for our own account.

The following table summarizes our aircraft portfolio by aircraft type and by ownership status as of May 31, 2008:

Aircraft Type	Joint Venture Portfolio	Wholly-Owned Portfolio
MD80 series	—	2
737-300 series	7	1
737-400 series	18	—
737-500 series	—	1
757-200 series	1	—
767-300 series	2	—
747-400 series	1	—
A320	—	3
CRJ200	—	1

Total	29	8

At May 31, 2008, all aircraft wholly-owned or through joint venture are on lease, with 24 of the aircraft on lease outside of North America. During the fiscal year ended May 31, 2009 ("fiscal 2009"), four 737-300's in the joint venture portfolio will be up for lease renewal and one 737-300 in the wholly-owned portfolio will be up for lease renewal. The oldest aircraft in the portfolio of 37 aircraft is 21 years old and the newest aircraft is nine years old. The average age of our fleet is 16 years. Our total investment in the joint venture and wholly-owned aircraft portfolio is approximately $121,500. Within Aircraft Sales and Leasing segment, we also provide advisory services which consist of assistance in remarketing aircraft, records management and storage maintenance.

Raw Materials

We historically have been able to obtain raw materials and other items for our inventories for each of our segments at competitive prices, terms and conditions from numerous sources, and we expect to be able to continue to do so.

Terms of Sale

In the Aviation Supply Chain, Maintenance, Repair and Overhaul, and Structures and Systems segments, we generally sell our products under standard 30-day terms. On occasion, certain customers (principally foreign customers) will negotiate extended payment terms (60-90 days). Except for customary warranty provisions, customers do not have the right to return products nor do they have the right to extended financing. In the Aircraft Sales and Leasing segment, we sell our products on a cash due at delivery basis, standard 30-day terms or on an extended term basis and aircraft purchasers do not have the right to return the aircraft. Our contracts with the U.S. Department of Defense and its contractors are typically firm 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 U.S. Department of Defense.

Customers

For each of our reportable segments, we market and sell products and services primarily through our own employees. In certain markets, we rely on foreign sales representatives to assist in the sale of our products and services. The principal customers for our products and services in the Aviation Supply Chain and Maintenance, Repair and Overhaul segments are domestic and foreign commercial airlines, regional and commuter airlines, business and general aviation operators, original equipment manufacturers, aircraft leasing companies, domestic and foreign military organizations and independent aviation support

companies. In the Structures and Systems segment, our principal customers include domestic and foreign defense organizations, domestic and foreign passenger and freight airlines, original equipment manufacturers, large system providers and other industrial entities. The principal customers in the Aircraft Sales and Leasing segment include domestic and foreign commercial airlines and aircraft finance and leasing companies. Sales of aviation products and services to our 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 and the level of sales of new and used aircraft. Sales to the U.S. Department of Defense are subject to a number of factors, including the level of troop deployment worldwide, competitive bidding, government funding and requirements generated by world events.

Licenses

We have 12 Federal Aviation Administration (FAA) licensed repair stations in the United States and Europe. Of the 12 licensed FAA repair stations, seven 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 12 FAA licensed repair stations, four are in the Aviation Supply Chain segment, six are in the Maintenance, Repair and Overhaul segment, and two are in the Structures and Systems segment. Of the seven EASA licensed repair stations, two are in the Aviation Supply Chain segment, four are in the Maintenance, Repair and Overhaul segment and one is in the Structures and Systems segment. We believe that we possess all licenses and certifications that are material to the conduct of our business.

Competition

Competition in our markets is based on quality, ability to provide a broad range of products and services, speed of delivery and price. Competitors in both the Aviation Supply Chain and the Maintenance, Repair and Overhaul segments include original equipment manufacturers, the service divisions of large commercial airlines and other independent suppliers of parts and repair and overhaul services. Our engineering, manufacturing, machining and integration activities in our Structures and Systems segment compete with a number of divisions of large corporations and other large and small companies. In our Aircraft Sales and Leasing segment, we face competition from financial institutions, syndicators, hedge funds, commercial and specialized leasing companies and other entities that provide financing. Although certain of our competitors have substantially greater financial and other resources than we do, in each of our four reportable segments 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, 2008, backlog believed to be firm was approximately $466,700 compared to $319,700 at May 31, 2007. These amounts do not include expected sales from the A400M cargo system. Approximately $412,400 of our May 31, 2008 backlog is expected to be filled within the next 12 months. The increase in our backlog principally reflects an increase in backlog in our Aviation Supply Chain segment and in our Structures and Systems segment mainly due to the impact of the acquisition of Summa.

Employees

At May 31, 2008, we employed approximately 5,400 persons worldwide. We also retain approximately 750 contract workers, the majority of which are located at our airframe maintenance facilities.

Sales to Defense Customers

Sales to global defense customers were $518,796 (37.5% of total sales) in fiscal 2008. Sales to the U.S. Department of Defense and its contractors were $438,501 (31.7% of total sales), $325,280 (30.7% of total sales) and $293,778 (33.2% of total sales) in fiscal years 2008, 2007 and 2006, respectively. Because such sales are subject to competitive bidding and U.S. government funding, no assurance can be given that such sales will continue at levels previously experienced. The majority of our U.S. government contracts are for products and services used for ongoing military logistic support activities and are subject to changes in defense spending. Our U.S. government contracts are subject to termination at the election of the U.S. government; in the event of such a termination we would be entitled to recover from the U.S. government all allowable costs incurred by us through the date of termination.

ITEM 1A. RISK FACTORS

The following is a description of some of the principal risks inherent in our business. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties not presently known to us, or that we currently deem immaterial, could adversely impact our results of operations or financial condition in the future.

We are affected by factors that adversely affect the aviation industry.

As a provider of products and services to the aviation industry, we are greatly affected by overall economic conditions of that industry. The aviation industry is historically cyclical and has been negatively affected in recent years by the terrorist attacks of September 11, 2001, the subsequent decline in air travel, historically high oil prices, the war on terrorism and the outbreak of Severe Acute Respiratory Syndrome, or SARS. As a result of these and other events, certain customers filed for bankruptcy protection over the past several years, and others may be forced to do so in the future.

More recently, since the early part of calendar year 2008, most U.S. air carriers have announced a new wave of cost reduction initiatives, including staffing reductions, route consolidations and capacity reductions. We believe the announced capacity reductions impact 10-15% of the U.S. fleet and principally impact older-generation narrow-body and certain regional aircraft. The announced fleet reductions are in response to record high oil prices and softening economic conditions in the U.S., and are expected to be mostly implemented beginning in the fall of 2008. In addition, certain air carriers have ceased operations. A reduction in the operating fleet of passenger 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.

There has also been tightening in the credit markets which may affect our customers' ability to raise debt or equity capital. This may reduce the amount of liquidity available to our customers which may limit their ability to buy parts, services and aircraft. There is also uncertainty over the direction of the U.S. economy as a result of slower growth rates, higher unemployment and the weak housing market.

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

•: continued historically high oil prices;
•: future terrorist attacks and the ongoing war on terrorism;
•: 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; and
•: future outbreaks of infectious diseases.

Our customers may not be able to meet their financial obligations to us or we may experience less business as a result of the current airline environment, which would adversely affect our financial condition and results of operations.

Mesa Airlines and subsidiaries ("Mesa") is a customer of the Company and in May 2008, warned it may have to file for bankruptcy protection if it could not resolve a contract dispute with one of its customers. During fiscal 2008, our consolidated sales to Mesa were $73,000, of which $56,000 was in the Aviation Supply Chain segment and $17,000 in the Maintenance, Repair and Overhaul segment. At

May 31, 2008, we have inventory of $4,000 and other long-term assets recorded in equipment on long-term lease of $51,000 supporting the Mesa supply chain programs and also have trade receivables and other assets associated with Mesa of approximately $13,000.

In addition to Mesa, a number of our existing and prospective worldwide airline customers continue to suffer from the problems affecting the aviation industry, and some have filed for bankruptcy protection. As a result, we may sell fewer parts and services to these customers and certain of these customers continue to pose credit risks to us. Our inability to collect receivables from one or more important customers, including Mesa, would adversely affect our results of operations and financial condition.

The market value for our aviation products fluctuates.

We have used a number of assumptions when determining the recoverability of inventories and 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. Principally as a result of the events of September 11, 2001 and its impact on the global airline industry's financial condition, fleet size and aircraft utilization, we recorded a significant charge for impaired inventories and engines during the second quarter of fiscal 2002 utilizing those assumptions. During the fourth quarter of fiscal 2003 and the first quarter of fiscal 2007, we recorded additional charges as a result of a further decline in market value for certain of these inventories, aircraft and engines. Further 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 additional impairment charges in future periods. We can give no assurance that future impairment charges for our inventories, aircraft and engines will not occur.

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

During fiscal 2008 and 2007, we completed four acquisitions. Further, 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 of the acquired business, the effects of amortization of any acquired intangible assets and the potential impairment of goodwill on our financial results, and the potential loss of key employees of the acquired business. For the acquisitions we made during fiscal 2008 and fiscal 2007, and for any additional businesses we may acquire in the future, we may not be able to execute our operational, financial or integration plan of the acquired businesses, which could adversely affect our results of operations and financial condition.

Our 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 the U.S. Department of Defense and its contractors were approximately $438,501 (31.7% of consolidated sales) in fiscal year 2008. The majority of our U.S. government contracts are for products and services used for ongoing military logistic support activities and for products which support the U.S. military's deployment strategy. Our contracts with the U.S. Department of Defense and its contractors are typically firm 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 U.S. Department of Defense. Sales to the U.S. Department of Defense are subject to a number of factors, including the level of troop deployment worldwide, competitive bidding, U.S. government funding and requirements generated by world events, and therefore may not continue at levels previously experienced, which could have an adverse effect on 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 under firm contracts providing for fixed prices for the products and services, 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.

We may be unable to re-lease or sell aircraft and engines when their current leases expire.

We purchase and lease aircraft and engines to our customers on an operating lease basis. Our ability to re-lease or sell these assets on acceptable terms 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. During fiscal 2009, five 737-300's in our aircraft portfolio are up for lease renewal. Our inability to re-lease these aircraft, or other aircraft and engines that are currently on lease, could adversely affect our results of operations and financial condition.

Significant cost issues may develop associated with the A400M Cargo system.

In June 2005, we announced that our Cargo Systems business in our Structures and Systems segment was selected to provide cargo handling systems for the new A400M Military Transport Aircraft (A400M). We are a subcontractor to Pfalz Flugzeugwerke GmbH (PFW) of Speyer, Germany on this Airbus program. We have incurred, and are expected to continue to incur, significant development costs in connection with this program. Our portion of revenue to be generated from this program is expected to exceed $300,000 through fiscal 2015, based on current sales projections for the A400M as provided to us by Airbus. Based on program delays and information provided by Airbus, planned first shipments under this program have slipped from the second half fiscal 2008 to late fiscal 2009. If the A400M experiences significant additional delivery delays or order cancellations, or if we fail to develop the system according to contract specifications, then we may not be able to recover our development costs, and our operating results and financial condition could be adversely affected.

Success within our Maintenance, Repair and Overhaul segment is dependent upon continued outsourcing by the airlines.

We currently conduct airframe maintenance, repair and overhaul activities at leased facilities in Indianapolis, Indiana; Oklahoma City, Oklahoma; Miami, Florida; and Hot Springs, Arkansas. Revenues at these facilities fluctuate based on the 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 the number of aircraft operating decline or outsourcing of maintenance activities decline, we may not be able to execute our operational and financial plan at our MRO facilities, which could adversely affect our results of operations and financial condition.

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

The aviation industry and the markets for our products and services are highly competitive, and we face competition from a number of sources, both domestic and international. Our competitors include aircraft manufacturers, aircraft parts manufacturers, airline and aircraft service companies, other companies providing maintenance, repair and overhaul services, and other aircraft spare parts distributors and redistributors. Some of our competitors have substantially greater financial and other resources than we have. These competitive pressures 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 continuing availability of debt and equity capital. Access to the debt and equity capital markets may be limited by various factors, including general economic conditions, the state of the aviation industry, our financial performance and current 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 of our loan 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 agreements and would result in a cross-default under other loan agreements. In the event of a default and our inability to obtain a waiver of the default, all amounts outstanding under loan 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.

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 the 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 other countries. We also operate repair stations that are licensed by the FAA and the equivalent regulatory agencies in other countries. 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. If material licenses, authorizations or approvals were revoked or suspended by the FAA and in some cases the equivalent regulatory agencies in other countries, our results of operations and financial condition may be adversely affected.

The FAA, airlines and others in the industry have heightened their sensitivity and scrutiny with respect to compliance with approved maintenance procedures. Additionally, aircraft maintenance and the FAA's oversight of maintenance activities has become a prevalent topic in the media. Our results of operations could be adversely affected as a result of negative publicity associated with recent media activity and increased FAA scrutiny of air carrier and MRO maintenance activities, even if our procedures continue to meet applicable regulatory and original equipment manufacturer's requirements.

Our industry is susceptible to product 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 personal 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 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 can give no assurance that we will be able to maintain adequate insurance coverage in the

future at an acceptable cost. Any product liability claim not covered by adequate insurance could adversely affect our results of operations 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 of substances into the environment, the disposal of hazardous wastes, 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. Information on an administrative proceeding by the Michigan Department of Environmental Quality is contained under Item 3 of this Annual Report on Form 10-K.

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

The aviation industry is 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 capital expenditures to purchase new equipment and to train our employees to keep pace with any new technological developments. These capital 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.

Because of the complex nature of many of our products and services, we are generally dependent on an educated and highly skilled workforce. Furthermore, we have collective bargaining agreements covering approximately 650 employees at two of our business units. 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, and may adversely affect our results of operations and financial condition.

ITEM 2. PROPERTIES

Our principal activities in the Aircraft Sales and Leasing segment and parts distribution activities in the Aviation Supply Chain segment are conducted from a building in Wood Dale, Illinois, which we own subject to a mortgage. In addition to warehouse space, this facility includes executive, sales and administrative offices. We also lease facilities in Atlanta and Macon, Georgia; Jacksonville, Florida; Garden City, New York and London, England, and we own a building near Schiphol International Airport in the Netherlands to support activities in the Aviation Supply Chain segment.

Our principal activities in the Maintenance, Repair and Overhaul segment are conducted at facilities leased by us located in Indianapolis, Indiana; Oklahoma City, Oklahoma; Miami, Florida; Roswell, New Mexico and Hot Springs, Arkansas.

Our principal activities in the Structures and Systems segment are conducted at facilities owned by us in Clearwater, Florida (subject to an industrial revenue bond); Cadillac and Livonia, Michigan; Goldsboro, North Carolina and Frankfort, New York. We also lease facilities in Huntsville, Alabama; Cullman, Alabama; Lebanon, Kentucky and Sacramento, California.

We also operate sales offices which support all our activities and are leased in London, England; Melbourne, Australia; Paris, France; Rio de Janeiro, Brazil; Shanghai, China; Singapore, Republic of Singapore and Tokyo, Japan.

We believe that our owned and leased facilities are suitable and adequate for our operational requirements.

ITEM 3. LEGAL PROCEEDINGS
(Dollars in thousands)

Except as described below, we are not a party to any material, pending legal proceeding (including any governmental or environmental proceedings) other than routine litigation incidental to our business.

AAR Manufacturing, Inc., a subsidiary of the Company ("subsidiary") received an Administrative Order for Response Activity ("Order") dated August 7, 2003, from the Michigan Department of Environmental Quality ("MDEQ") relating to environmental conditions at and in the vicinity of the subsidiary's Cadillac, Michigan plant. The Order requires the subsidiary to perform environmental investigatory work, prepare a feasibility study and a remedial action plan, and perform interim response actions. The interim response actions include continuation of the response activities the subsidiary is performing under a 1985 Consent Decree, operation of a soil vapor extraction system the subsidiary had previously installed and operated, determination of the need to provide alternate water supplies to off-site properties (and if it is so determined then to actually provide them), removal of any free phase liquids encountered in the ground, providing notices of groundwater contamination migration to off-site property owners, and other actions determined by the MDEQ or the subsidiary to be appropriate. The MDEQ further demands payment of environmental response costs already incurred by the MDEQ in the approximate amount of $2,500 plus interest, and reimbursement of unspecified costs to be incurred in the future by the MDEQ. The Order and the letter accompanying it threaten the imposition of civil fines up to $25 for each day of violation of the Order, plus exemplary damages up to three times the costs incurred by the MDEQ if the subsidiary does not comply with the Order. The Order may require the implementation of the remedial action plan, although it is not clear on that point. The Order requires the implementation of emergency response action if a release of hazardous substances, threat of a release, or exacerbation of existing contamination occurs during the pendency of the Order.

MDEQ responded to the subsidiary by saying that the MDEQ "will be taking appropriate action to protect public health, safety and welfare and the environment, and gain AAR's compliance with Part 201" (the Michigan "cleanup law").

On March 31, 2005, a complaint was filed by the MDEQ in Cadillac, Michigan with the Wexford County Circuit Court. The case is Michigan Department of Environmental Quality v AAR Cadillac Manufacturing, a division of AAR Manufacturing Group, Inc., an Illinois corporation, and AAR Corp., a Delaware corporation, File No. 05-18853-CE. In its complaint, the MDEQ seeks to enforce the Order against the subsidiary and to have the Court impose civil fines and exemplary damages upon the subsidiary for the alleged failure to comply with the Order. The MDEQ seeks to recover its costs incurred in performing response activities from both the subsidiary and the Company and seeks a declaratory judgment that both are liable for all future costs incurred by the State at the facility. The MDEQ also seeks civil fines from the subsidiary for alleged violations of a particular section of a Michigan environmental law.

The Company and the subsidiary filed their Answer, including Affirmative Defenses, and intend on vigorously defending the complaint filed by the MDEQ. No trial date has been set.

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

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 four business segments: Aviation Supply Chain; Maintenance, Repair and Overhaul; Structures and Systems; and Aircraft Sales and Leasing.

Sales in the Aviation Supply Chain 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 defense markets, as well as the repair and overhaul of a wide range of commercial and military aircraft parts and components. We also offer customized programs for inventory supply and management and performance-based logistics. Sales also include the sale and lease of commercial jet engines. Cost of sales consists principally of the cost of product (primarily aircraft and engine parts), direct labor and overhead (primarily indirect labor, facility cost and insurance).

Sales in the Maintenance, Repair and Overhaul segment are principally derived from aircraft maintenance and storage and the repair and overhaul of landing gear. Cost of sales consists principally of the cost of product (primarily replacement aircraft parts), direct labor and overhead.

Sales in the Structures and Systems segment are derived from the engineering, design and manufacture of containers, pallets and shelters used to support the U.S. military's tactical deployment requirements, complex machined and fabricated parts, components and sub-systems for various aerospace and defense programs and other applications, in-plane cargo loading and handling systems for commercial and military applications and composite products for aviation and industrial use. Cost of sales consists principally of the cost of product, direct labor and overhead.

Sales in the Aircraft Sales and Leasing segment are derived from the sale and lease of commercial aircraft and technical and advisory services. Cost of sales consists principally of the cost of product (aircraft), labor and the cost of lease revenue (primarily depreciation and insurance).

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 tables below set

forth consolidated sales and gross profit for our four business segments for each of the last three fiscal years ended May 31.

Business Trends and Highlights

Our consolidated sales growth over the past three fiscal years has been driven by double-digit sales increases in each of our segments, fueled by market share gains through solid execution across our segments and broad market acceptance of our value proposition offering commercial and defense customer's cost-effective supply solutions. We also benefited from the trend toward outsourcing maintenance, repair and overhaul and part support activities from commercial and defense customers, as well as the impact of acquisitions and increased demand from defense customers as a result of the geo-political environment.

Since the early part of calendar year 2008, most U.S. air carriers have announced a new wave of cost reduction initiatives, including staffing reductions, route consolidations and capacity reductions. We believe the announced capacity reductions impact 10-15% of the U.S. fleet and principally impact older-generation narrow-body and certain regional aircraft. The announced fleet reductions are in response to record high oil prices and softening economic conditions in the U.S., and are expected to be mostly implemented beginning in the fall of 2008. In addition, certain air carriers have ceased operations. A reduction in the operating fleet of passenger 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.

We expect many carriers will continue to seek ways to reduce their cost structure, including outsourcing more of their maintenance and support functions to third parties, while we believe other carriers who have historically outsourced their maintenance requirements will continue to do so. Although we believe we remain well positioned to respond to the market with our broad range of products and

services as these trends continue to develop, the factors above may have an adverse impact on our growth rates and our results of operations and financial condition.

We continue to see opportunities to provide performance-based logistics services and mobility products supporting our defense customers' deployment activities. Although it remains difficult for us to predict long-term demand for these types of products and services, we believe we are well positioned with our current portfolio of products and services and growth plans to benefit from longer-term U.S. military deployment and program management strategies.

Results of Operations

Fiscal 2008 Compared with Fiscal 2007

Consolidated sales for fiscal 2008 increased $323,750 or 30.5% over fiscal 2007 as all four of our reportable segments experienced an increase in sales. Overall sales growth was driven by market share gains through solid execution across our business and broad market acceptance of the Company's value proposition of innovative cost savings solutions. Sales to commercial customers increased 27.8% and sales to defense customers increased 36.7% compared to the prior year. The sales increase to commercial customers reflects market share gains, increased demand for airframe maintenance and landing gear overhaul, strength in supply chain programs, successful marketing efforts in international markets, increased aircraft sales and the impact from acquisitions. Sales to defense customers increased reflecting the favorable impact of acquisitions and continued strong demand for performance-based logistics programs and specialized mobility products.

In the Aviation Supply Chain segment, sales increased $62,816 or 11.6% over the prior year. The sales increase is attributable to strong demand for parts support from defense-related performance-based logistics programs and aftermarket parts sales to commercial customers. Gross profit in the Aviation Supply Chain segment increased $30,708 or 26.8% over the prior year primarily due to increased sales volume, and the gross profit margin percentage increased to 23.9% from 21.0% in the prior year due to the favorable mix of products sold and the $4,750 impairment charge recorded during the first quarter of fiscal 2007 (see Note 13 of Notes to Consolidated Financial Statements).

In the Maintenance, Repair and Overhaul segment, sales increased $89,355 or 42.2% over the prior year. The increase in sales is primarily attributable to increased revenues at the Indianapolis heavy maintenance facility, greater volume of landing gear overhauls and the inclusion of revenue from Avborne which was acquired in March 2008 and contributed approximately $16,000 of revenues during fiscal 2008 (see Note 7 of Notes to Consolidated Financial Statements). Gross profit in the Maintenance, Repair and Overhaul segment increased $14,052 or 47.0%, and the gross profit percentage increased to 14.6% from 14.1% in the prior year due to increased volume and operational improvement initiatives.

In the Structures and Systems segment, sales increased $125,345 or 47.5% over the prior year. The sales increase is attributable to sustained high levels of demand and new business wins for specialized mobility products, and the inclusion of revenue from Brown (acquired in April 2007) and Summa (acquired in December 2007) which together contributed approximately $88,800 of revenues during fiscal 2008 (see Note 7 of Notes to Consolidated Financial Statements). Gross profit in the Structures and Systems segment increased $18,652 or 51.8% compared to the prior year primarily due to increased sales while the gross profit margin percentage increased slightly to 14.0% from 13.6%.

In the Aircraft Sales and Leasing segment, sales increased $46,234 or 110.4% compared with the same period last year driven by the sale of five aircraft from our wholly-owned portfolio. Gross profit in the Aircraft Sales and Leasing segment increased $16,513 as a result of increased aircraft sales and the $2,902 impairment charge recorded during the first quarter of fiscal 2007 (see Note 13 of Notes to Consolidated Financial Statements). Our recent strategy in the Aircraft Sales and Leasing segment has been to invest in aircraft mostly through participation in joint ventures and for our own account. During fiscal 2008, we purchased 20 aircraft with joint venture partners, all of which are currently on lease. At May 31, 2008, the

total number of aircraft held in joint ventures was 29 (see Note 8 of Notes to Consolidated Financial Statements). Earnings from joint ventures declined $5,004 as aircraft joint ventures had less sales activity in fiscal 2008 compared to fiscal 2007. We also own eight aircraft outside of the joint ventures. Of the eight aircraft owned by us outside the aircraft joint ventures, four were acquired prior to September 11, 2001.

Operating income increased $39,152 or 41.1% compared to the same period last year due to increased sales and gross profit, partially offset by an increase in selling, general and administrative expenses. Selling, general and administrative expenses increased $30,411 reflecting the impact of acquisitions, increased spending to support growth and investments in operational improvement initiatives. Interest expense increased $3,877 as a result of an increase in the average outstanding borrowings under our unsecured revolving credit facility to support growth, as well as an increase in non-recourse borrowings to acquire aircraft. Interest income and other decreased $3,476 principally as a result of lower yields on invested cash, as well as a decline in average invested cash balances. Our effective income tax rate increased to 34.8% compared to 32.0% in the prior year due to the expiration of certain income tax benefits on export activities.

During the third quarter of fiscal 2007, we decided to exit our non-core industrial turbine business, which was part of the Structures and Systems segment, and classified the results as a discontinued operation (see Note 11 of Notes to Consolidated Financial Statements).

Income from continuing operations was $75,745 compared to $59,447 in the prior year due to the factors discussed above.

Fiscal 2007 Compared with Fiscal 2006

Consolidated sales for fiscal 2007 increased $175,651 or 19.8% over the prior year. Each reporting segment experienced sales growth with sales to commercial customers increasing 24.3% and sales to defense customers up 14.4% compared to the prior year. The sales increase to commercial customers reflects the improved commercial airline environment, our expanded presence in global markets, growth in supply chain programs, and increased demand for airframe maintenance and landing gear overhaul services. Sales to defense customers increased as we continue to experience strong demand for performance-based logistics programs and specialized mobility products and the impact from acquisitions.

Sales in the Aviation Supply Chain segment increased $82,508 or 17.9% over the prior year. The sales increase reflects strong demand for engine and airframe parts from commercial customers due to improved sourcing and program execution as well as the implementation of new supply chain programs. The increase in sales to defense customers was driven by continued strong demand for parts support from performance-based logistics programs. Gross profit in the Aviation Supply Chain segment increased $15,128 or 15.2% over the prior year primarily due to increased sales volume, partially offset by an impairment charge of $4,750 recorded in this segment during the first quarter of fiscal 2007 (see Note 13 of Notes to Consolidated Financial Statements). The gross profit margin percentage decreased slightly to 21.0% from 21.5% in the prior year due to the unfavorable mix of products sold and the impairment charge.

In the Maintenance, Repair and Overhaul segment, sales increased $29,258 or 16.1% over the prior year. The increase in sales is primarily attributable to increased demand for landing gear overhaul services as well as airframe maintenance at our Oklahoma and Indianapolis airframe maintenance facilities. Gross profit in the Maintenance, Repair and Overhaul segment increased $4,001 or 15.4% over the prior year due to the increase in sales and the gross profit margin percentage decreased slightly to 14.1% from 14.2%. The gross profit margin improved at our landing gear and Oklahoma airframe maintenance businesses due to increased sales and operational efficiencies. The gross profit margin declined at our Indianapolis airframe maintenance facility due to start-up inefficiencies associated with new customers.

In the Structures and Systems segment, sales increased $35,336 or 15.4% over the prior year. The increase in sales was primarily due to the development and delivery of increasingly complex and specialized

shelter products and higher volume of pallets at our Mobility Systems business. Sales also increased due to the inclusion of $12,368 of revenue from Brown which was acquired during the fourth quarter of fiscal 2007 (see Note 7 of Notes to Consolidated Financial Statements). Sales of our cargo systems were lower as we relocated production to a new manufacturing facility in North Carolina. Gross profit in the Structures and Systems segment increased $2,310 or 6.9% compared to the prior year due to the increase in sales. The gross profit margin percentage decreased from 14.7% to 13.6% due to the mix of products sold, primarily at our Mobility Systems business.

In the Aircraft Sales and Leasing segment, sales increased $28,549 due to more aircraft sales compared to the prior year. During fiscal 2007, our joint ventures purchased six aircraft and sold ten. The increase in earnings from aircraft joint ventures compared to the prior year is primarily due to the sale of the ten aircraft. At May 31, 2007, the total number of aircraft held in joint ventures was 12. Our strategy in the Aircraft Sales and Leasing segment is to build an aircraft portfolio through participation in joint ventures and for our own account. At May 31, 2007, we owned nine aircraft outside of the joint ventures. Of the nine aircraft owned by us outside the aircraft joint ventures, five were acquired prior to September 11, 2001. Gross profit in the Aircraft Sales and Leasing segment decreased $513 compared to the prior year principally due to the impairment charge of $2,902 recorded during the first quarter of fiscal 2007 (see Note 13 of Notes to Consolidated Financial Statements).

In the first quarter of fiscal 2007, we recorded an impairment charge of $4,750 in the Aviation Supply Chain segment for engine parts that were acquired prior to September 11, 2001, and were subject to impairment charges recorded in prior years. This impairment charge was triggered by our decision to aggressively pursue the liquidation of this inventory. We made this decision to recognize the impairment due to the impact of persistently high fuel costs and fewer operators on demand for these parts, as well as to better align human and physical resources with higher potential opportunities in the rapidly growing Aviation Supply Chain segment (see Note 13 of Notes to Consolidated Financial Statements). In the Aircraft Sales and Leasing segment, we recorded an impairment charge of $2,902 during the first quarter of 2007 on a wide-body aircraft originally purchased prior to September 11, 2001. The lease and non-recourse debt on the aircraft were restructured during the quarter, and we made the decision to offer the aircraft for sale and recorded the impairment charge to reduce the carrying value of the aircraft to estimated net realizable value. As part of the restructuring, the lender of the non-recourse debt reduced the outstanding principal balance by $2,927 which resulted in a gain on extinguishment of the same amount.

During the first quarter of fiscal 2007, we sold substantially all assets, subject to certain liabilities, of a product line within our Structures and Systems segment. Proceeds from the sale of the product line were $6,567 and the net carrying value of the assets sold was $1,209, resulting in a gain on sale of product line of $5,358. The gain on this transaction has been classified as a component of operating income in accordance with Statement of Financial Accounting Standards (SFAS) No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets".

Operating income increased $30,194 or 46.3% compared with the prior year's period due to increased sales, increased earnings from aircraft joint ventures and the gain on the sale of a product line, partially offset by impairment charges and an increase in selling, general and administrative expenses. In fiscal 2007, our selling, general and administrative expenses increased $5,540 or 5.6% over the prior year primarily due to increased resources to support our growth. Selling, general and administrative expenses as a percentage of sales decreased to 9.9% compared to 11.2% in the prior year. Interest expense decreased $1,303 or 7.2% primarily due to a reduction in average outstanding borrowings on our revolving credit agreements during fiscal 2007, as well as capitalized interest of $977. Interest income and other increased $2,593 or 80.1% due to higher average invested cash during the current fiscal year, as well as a $915 gain on sale of an equity security. Our effective income tax rate for fiscal 2007 was 32.0% compared to 23.0% in the prior year due to lower tax benefits on export activities.

During the third quarter of fiscal 2007, we decided to exit our non-core industrial turbine business, which was part of the Structures and Systems segment, and classified the results as a discontinued operation. Sales for this business were $7,778 in fiscal 2007 (see Note 11 of Notes to Consolidated Financial Statements).

Net income increased to $58,660 for fiscal 2007 compared to $35,163 in the prior year due to the factors discussed above.

Legal Matters

The subsidiary advised the MDEQ that it would perform the requirements of the Order to the extent those requirements apply to the allegation by the MDEQ that a release of hazardous substances occurred after the execution of the 1985 Consent Decree. The subsidiary declined to perform certain work required by the Order that the subsidiary believes is based on claims resolved in the 1985 Consent Decree. The MDEQ responded to the subsidiary by saying that the MDEQ "will be taking appropriate action to protect public health, safety and welfare and the environment, and gain AAR's compliance with Part 201" (the Michigan "cleanup law").

The Company and the subsidiary filed their Answer, including Affirmative Defenses, and intend on vigorously defending the complaint filed by the MDEQ. No trial date has been set.

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.

Liquidity and Capital Resources

Historically, we have funded our operating activities and met our commitments through the generation of cash from operations, augmented by the periodic issuance of common stock and debt in the public and private markets. In addition to these cash sources, our current capital resources include our unsecured 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 general economic conditions, airline industry conditions, geo-political events, including the war on terrorism, and our operating performance. Our ability to generate cash from operations is influenced primarily by our operating performance and changes in working capital. We have a universal shelf registration on file with the Securities and Exchange Commission under which, subject to market conditions, up to $163,675 of common stock, preferred stock or medium- or long-term debt securities may be issued or sold.

At May 31, 2008, our liquidity and capital resources included cash of $109,391 and working capital of $564,932. On August 31, 2007, we amended our credit agreement dated August 31, 2006 (the "Credit Agreement") with various financial institutions, as lenders, and LaSalle Bank National Association, as administrative agent for the lenders (the "Amendment"). The Amendment increased our unsecured revolving credit amount to $250,000 from $140,000. Under certain circumstances, we may request an increase to the revolving commitment by an aggregate amount of up to $75,000, not to exceed $325,000 in total. The Amendment extended the term of our Credit Agreement from August 31, 2010 to August 31, 2011. The Amendment also modified the borrowing rate of the Credit Agreement and borrowings now bear interest at the London Interbank Offered Rate ("LIBOR") plus 100 to 225 basis points based on certain financial measurements. In March 2008, a second amendment to the Credit Agreement modified the borrowing rate to LIBOR plus 100 to 237.5 basis points based on certain financial measurements. There were no borrowings outstanding under this facility at May 31, 2008, however, there were approximately $18,000 of letters of credit against this facility. In addition to our domestic facility, we also have $2,479 available under a foreign line of credit. During February 2008, we completed the sale of $250,000 of convertible notes, consisting of $137,500 aggregate principal amount of 1.625% convertible senior notes due 2014 and $112,500 aggregate principal amount of 2.25% convertible senior notes due 2016 (see Note 2 of Notes to Consolidated Financial Statements).

During fiscal 2008, we generated $16,926 of cash from operations reflecting net income and depreciation and amortization of $115,096, an increase of accrued liabilities of $19,131 and a reduction in accounts receivable of $12,428. During fiscal 2008, cash flow from operations was unfavorably impacted by investments in inventories and equipment on short-term lease of $87,028 to support growth in the Aviation Supply Chain and Structures and Systems segments and a reduction in accounts payable of $26,078.

During fiscal 2008, our investing activities used $141,965 of cash principally as a result of the acquisitions of Summa and Avborne of $85,210, investments in aircraft joint ventures of $23,609 reflecting the purchase of 20 aircraft with our partner, and capital expenditures of $30,334.

During fiscal 2008, we generated $151,021 of cash from financing activities primarily due to the net proceeds received from the issuance of the $250,000 convertible senior notes, proceeds from borrowings related to aircraft financings of $22,681, proceeds from a capital lease obligation of $12,880, proceeds from the sale of warrants related to the convertible note offering of $40,114, proceeds from stock option exercises of $6,169 and tax benefits from the exercise of stock options of $4,657. Uses of cash from financing activities included the purchase of note hedges related to the convertible note offering of $69,676, purchase of treasury stock of $9,527, financing costs associated with debt issuances of $6,653 and reduction in borrowings of $99,541.

Purchase obligations 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. 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, 2008 was approximately $18,032.

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, 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 the customer's current and expected future financial performance.

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. Provisions 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. During the first quarter of fiscal 2007, we recorded an impairment charge related to certain engine parts in the amount of $4,750. These parts were acquired prior to September 11, 2001, and were subject to impairment charges recorded in fiscal 2002 and 2003. The fiscal 2007 impairment charge was triggered by the Company's decision to aggressively pursue the liquidation of this inventory. The Company made this decision to recognize the impairment due to the impact of persistently high fuel costs and reduced demand for these parts, as well as to better align human and physical resources with higher potential opportunities in the rapidly growing Aviation Supply Chain segment. 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 additional 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. In connection with these programs, we are required to make certain judgments and estimates concerning 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.

In accordance with SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets", 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 the provisions of SFAS No. 144 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.

Program Development Costs

In June 2005, we announced that our Cargo Systems business was selected to provide cargo handling systems for the new A400M cargo aircraft. We are subcontractor to PFW on this Airbus program. Our portion of the revenue from this program is expected to exceed $300,000 through fiscal 2015, based on sales projections of the A400M. As of May 31, 2008, we have incurred approximately $43,000 of costs associated with the engineering and development of the cargo system and have capitalized these costs in accordance with SOP 81-1 "Accounting for Performance of Construction—Type and Certain Production—

Type Contracts". 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 utilized certain judgments and estimates concerning expected revenues and the cost to manufacture the A400M cargo system. Differences between actual results and the assumptions utilized by us may result in us not fully recovering the value of the program development costs, which would unfavorably impact our financial condition and results of operations.

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.

Our discount rate is determined based on a review of long-term, high quality corporate bonds as of May 31, 2008 and models that match projected benefit payments to coupons and maturities from the high quality bonds. The assumption for the expected long-term return on plan assets is developed through analysis of historical asset returns by investment category, our fund's actual return experience and current market conditions. Changes in the discount rate and differences between expected and actual return on plan assets may impact the amount of net periodic pension expense recognized in our consolidated statement of operations.

New Accounting Standards

In September 2007, the Financial Accounting Standards Board (FASB) issued SFAS No. 157 (SFAS 157) "Fair Value Measurements." SFAS 157 establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007 for financial assets and liabilities, as well as for any other assets that are carried at fair value on a recurring basis in financial statements. In November 2007, the FASB provided a one year deferral of the implementation of SFAS 157 for other non-financial assets and liabilities. We continue to review the impact of SFAS 157 on our financial statements, but do not expect a material impact on our results of operations or financial condition.

In February 2007, the FASB issued SFAS No. 159 (SFAS 159), "The Fair Value Option for Financial Assets and Financial Liabilities—Including an Amendment to FASB Statement No. 115." SFAS 159 allows companies, at specified election dates, the option to measure certain financial assets and liabilities at fair value. The election, which is applied on an instrument by instrument basis, is typically irrevocable once made. Subsequent unrealized gains and losses on items for which the fair value option has been elected are to be reported in earnings. SFAS 159 is effective for fiscal years beginning after November 15, 2007. We continue to review the impact of SFAS 159 on our financial statements, but do not expect a material impact on our results of operations or financial condition.

In December 2007, the FASB issued SFAS No. 160 (SFAS 160), "Noncontrolling Interests in Consolidated Financial Statements—an Amendment of ARB 51." This statement amends ARB 51 to establish accounting and reporting standards for the noncontrolling interest (minority interest) in a subsidiary and for the deconsolidation of a subsidiary. Upon its adoption, effective for us as of June 1, 2009, noncontrolling interests will be classified as equity in the Company's financial statements and income and comprehensive income attributed to the noncontrolling interest will be included in the Company's income and comprehensive income. The provisions of this standard must be applied retrospectively upon adoption. We are currently evaluating the impact of adopting SFAS 160 on our results of operations and financial position.

In December 2007, the FASB issued SFAS No. 141 (revised 2007) (SFAS 141(R)), "Business Combinations". SFAS 141(R) establishes principles and requirements for how an acquirer in a business combination recognizes and measures the assets acquired, liabilities assumed, and any noncontrolling

interest in the acquiree. The provisions of SFAS 141(R) are effective for our business combinations occurring on or after June 1, 2009.

In March 2008, the FASB issued SFAS No. 161 (SFAS 161), "Disclosures about Derivative Instruments and Hedging Activities." SFAS 161 amends and expands the disclosure requirements of SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities", and is effective for fiscal years beginning after November 15, 2008. We do not expect the adoption of SFAS 161 will have a material impact on our results of operations or financial condition.

In May 2008, the FASB issued Staff Position FSP APB 14-1 (FSP APB 14-1), "Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement)". FSP APB 14-1 requires companies that have issued convertible debt that may be settled wholly or partly in cash when converted, to account for the debt and equity components separately. The value assigned to the bond liability is the estimated value of a similar bond without the conversion feature as of the issuance date. The difference between the proceeds for the convertible debt and the amount reflected as a bond liability is recorded as additional paid-in-capital. Interest expense is recorded using the issuer's comparable debt rate. FSP APB 14-1 will be effective for us beginning June 1, 2009 (fiscal 2010) and will require retrospective application. We continue to review the impact of FSP APB 14-1 on our financial statements, however, we are currently estimating, based on the outstanding convertible notes at May 31, 2008, the implementation of FSP APB 14-1 will result in a reduction of our convertible notes of approximately $95,000, an increase in capital surplus of approximately $62,000 and an increase in deferred taxes of approximately $33,000. In addition, we expect the implementation of FSP APB 14-1 will reduce our diluted earnings per share by $0.12 to $0.15 per share in fiscal 2010.

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

Our exposure to market risk includes fluctuating interest rates under our credit agreements, foreign exchange rates and accounts receivable. See Part II, Item 8 for a discussion on accounts receivable exposure. During fiscal 2008, 2007 and 2006, we did not utilize derivative financial instruments to offset these risks.

At May 31, 2008, $231,968 was available under our Credit Agreement. Interest on amounts borrowed under this credit facility is LIBOR based. As of May 31, 2008, the outstanding balance under this agreement was $0. A hypothetical 10 percent increase to the average interest rate under the credit facilities applied to the average outstanding balance during fiscal 2008 would have reduced our pre-tax income by approximately $215 during fiscal 2008.

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 income (loss). A hypothetical 10 percent devaluation of foreign currencies against the U.S. dollar would not have had a material impact on our financial position or results of operations.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

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

We have audited the accompanying consolidated balance sheets of AAR CORP. and subsidiaries (the Company) as of May 31, 2008 and 2007 and the related consolidated statements of operations, stockholders' equity and cash flows for each of the years in the three-year period ended May 31, 2008. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of AAR CORP. and subsidiaries as of May 31, 2008 and 2007 and the results of their operations and their cash flows for each of the years in the three-year period ended May 31, 2008, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of the Company's internal control over financial reporting as of May 31, 2008, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated July 10, 2008 expressed an unqualified opinion on the effective operation of internal control over financial reporting.

1. Summary of Significant Accounting Policies

Description of Business

AAR CORP. is a diversified provider of products and services to the worldwide aviation and defense industries. 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; and aircraft sales and leasing. We serve commercial and governmental aircraft fleet operators, original equipment manufacturers, and independent service providers around the world, and various domestic and foreign military customers.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its 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 8 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. 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 certain long-term aircraft component maintenance agreements are recognized by the percentage of completion method, either based on the relationship of costs incurred to date to 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 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.

Goodwill

Under Statement of Financial Accounting Standards (SFAS) No. 142, "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.

The amount reported under the caption "Goodwill and other intangible assets, net" is comprised of goodwill and intangible assets associated with acquisitions we made, principally since the beginning of fiscal 1998. Each of the acquisitions involved a single business that now comprises or is included in a single operating segment. We were not required to allocate goodwill related to specific acquisitions across two or more segments. For the annual goodwill impairment test, we compare an estimate of the fair value of each of our reportable segments to its carrying amount. The estimated fair value of each reportable segment was determined utilizing a valuation technique based on a multiple of earnings.

Goodwill by reportable segment is as follows:

	May 31,
	2008		2007
Aviation Supply Chain	$	20,133	$	20,136
Maintenance, Repair and Overhaul		18,234		14,860
Structures and Systems		63,153		29,631

	$	101,520	$	64,627

The increase in goodwill during fiscal 2008 was attributable to the acquisitions discussed in Note 7. At May 31, 2008 and 2007, intangible assets, other than goodwill, are comprised of customer relationships and covenants not to compete as follows:

	May 31,
	2008			2007
Customer relationships	$	28,730		$	8,730
Covenants not to compete		1,760			960
Accumulated amortization		(2,291	)		(50	)

	$	28,199		$	9,640

Customer relationships are being amortized over five- to twenty-year periods and the covenants not to compete are being amortized over a three-year period. We have made a preliminary purchase price allocation for customer relationships and covenants not to compete for the Summa and Avborne acquisitions and are in the process of obtaining final valuations for the acquired net assets. The aggregate amount of amortization expense for intangible assets each of the next five fiscal years is $2,701 in 2009, $2,464 in 2010, $2,329 in 2011, $2,060 in 2012 and $1,836 in 2013.

1. Summary of Significant Accounting Policies (Continued)

Cash and Cash Equivalents

At May 31, 2008 and 2007, cash equivalents of approximately $5,005 and $0, respectively, consist of investments in certificates of deposit which mature within 90 days. The carrying amount of cash equivalents approximates fair value at May 31, 2008 and 2007.

Marketable Securities

At May 31, 2008, we have invested $3,044 in securities which are classified as available for sale and included in "Deposits, prepaids and other" in the Consolidated Balance Sheet. As of May 31, 2008, the unrealized gain on investment in available for sale securities was $65, net of tax, and was recorded as a component of "Other comprehensive income."

During fiscal 2008 and 2007, we sold investments in securities that were classified as available for sale. The gains on sale of these investments were $532 and $915 in fiscal 2008 and 2007, respectively, and are reported in "Interest income and other" on the Consolidated Statements of Operations.

Foreign 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 $24,112 and $22,098 at May 31, 2008 and 2007, respectively. 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.

Mesa is a customer of the Company and in May 2008, warned it may have to file for bankruptcy protection if it could not resolve a contract dispute with one of its customers. During fiscal 2008, consolidated sales to Mesa were $73,000, of which $56,000 was in the Aviation Supply Chain segment and $17,000 in the Maintenance, Repair and Overhaul segment. At May 31, 2008, we have inventory of $4,000 and other long-term assets recorded in equipment on long-term lease of $51,000 supporting the Mesa supply chain programs and also have trade receivables and other assets associated with Mesa of approximately $13,000. Mesa is current on their obligations to us and we continue to monitor their situation.

SFAS No. 107, "Disclosures about Fair Value of Financial Instruments," requires disclosure of the fair value of certain financial instruments. Cash and cash equivalents, accounts receivable, short-term borrowings and accounts payable are reflected in the consolidated financial statements at fair value

AAR CORP. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Dollars in thousands, except per share amounts)

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. Cost is determined by the specific identification, average cost or first-in, first-out methods. We also 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,
	2008		2007
Raw materials and parts	$	55,183	$	55,702
Work-in-process		47,576		36,580
Purchased aircraft, parts, engines and components held for sale		193,851		152,379

	$	296,610	$	244,661

Equipment under Leases

Lease revenue is recognized as earned. The cost of the asset under lease is original purchase price plus overhaul costs. Depreciation for aircraft is computed on a straight-line method over the estimated service life of the equipment. The balance sheet classification 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 consists of 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.

Our aircraft and engine portfolio recorded on our consolidated balance sheet includes eight narrow-body aircraft and several types of engines. Of the eight aircraft, four were acquired prior to September 11, 2001. Several engines also were acquired prior to September 11, 2001. Demand and lease rates for certain of these assets have not returned to pre-September 11, 2001 levels. In accordance with SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," we are required to test for impairment of these assets whenever certain conditions exist, and previously adjusted the carrying value for certain of these assets (see Note 13). During the first quarter of fiscal 2007, we recorded an impairment charge of $2,902 on a wide-body aircraft originally purchased prior to September 11, 2001. The lease and non-recourse debt on the aircraft were restructured during the quarter, and we made the decision to offer the aircraft for sale and recorded the impairment charge to reduce the carrying value of the aircraft to

estimated net realizable value. This aircraft was sold during the third quarter of fiscal 2008. When applying the provisions of SFAS No. 144 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. Unfavorable differences between actual results and expected results could result in future impairments in our aircraft and engine lease portfolio.

All of the aircraft in our aircraft portfolio are currently on lease. Future rent due to us under non-cancelable leases during each of the next five fiscal years is $32,896 in 2009, $27,128 in 2010, $22,010 in 2011, $22,089 in 2012 and $16,424 in 2013.

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. 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.

Leveraged Lease

We are an equity participant in a leveraged lease transaction. The equipment cost in excess of equity contribution is financed by a third party in the form of secured debt. Under the lease agreement, the third party has no recourse against us for nonpayment of the obligation. The third-party debt is collateralized by the lessees' rental obligation and the leased equipment.

We have ownership rights to the leased asset and are entitled to the tax deduction for depreciation on the leased asset and for interest on the secured debt financing.

Income taxes

Income taxes are determined in accordance with SFAS No. 109, "Accounting for Income Taxes".

Supplemental Information on Cash Flows

Supplemental information on cash flows follows:

	For the Year Ended May 31,
	2008		2007		2006

1. Summary of Significant Accounting Policies (Continued)

During the third quarter of fiscal 2008, the holders of $16,355 of 2.875% convertible notes redeemed their notes for 880,000 shares of our common stock. As a result of the redemption, common stock increased $880 and capital surplus increased $15,284.

In connection with the acquisition of Avborne, we assumed a $25,000 industrial revenue bond secured by maintenance hangars located at Miami International Airport. The industrial revenue bond matures on August 1, 2018 and has a variable interest rate. The interest rate at May 31, 2008 was 1.68%.

During the third quarter of fiscal 2006, we acquired $50,645 aggregate principal amount of our 2.875% Convertible Senior Notes due 2024, or approximately 76% of the previously outstanding principal amount, in exchange for an aggregate 2,724,000 newly issued shares of common stock plus $3,893 in cash, in privately negotiated transactions exempt from the registration requirements under the Securities Act of 1933, as amended. The number of shares issued was equivalent to the number into which the notes were convertible under the original terms of the notes. We recorded a $3,893 pre-tax loss on the exchange of the notes into stock in advance of the call date of the notes; this loss was comprised of interest that the note holders would otherwise have been entitled to receive as well as an incentive payment for the exchange. As a result of these transactions, our long-term debt decreased by $50,645 and stockholders' equity increased by $46,600.

During fiscal 2008, treasury stock increased $21,122 reflecting the purchase of treasury shares of $9,527 and the impact from the exercise of stock options of $11,595. During fiscal 2007 and 2006, treasury stock increased $10,149 and $19,167, respectively, principally reflecting the impact from the exercise of stock options.

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.

New Accounting Standards

In September 2007, the FASB issued SFAS No. 157 (SFAS 157) "Fair Value Measurements." SFAS 157 establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007 for financial assets and liabilities, as well as for any other assets that are carried at fair value on a recurring basis in financial statements. In November 2007, the FASB provided a one year deferral of the implementation of SFAS 157 for other non-financial assets and liabilities. We continue to review the impact of SFAS 157 on our financial statements, but do not expect a material impact on our results of operations or financial condition.

1. Summary of Significant Accounting Policies (Continued)

continue to review the impact of SFAS 159 on our financial statements, but do not expect a material impact on our results of operations or financial condition.

In December 2007, the FASB issued SFAS No. 141 (revised 2007) (SFAS 141(R)), "Business Combinations." SFAS 141(R) establishes principles and requirements for how an acquirer in a business combination recognizes and measures the assets acquired, liabilities assumed, and any noncontrolling interest in the acquiree. The provisions of SFAS 141(R) are effective for our business combinations occurring on or after June 1, 2009.

In March 2008, the FASB issued SFAS No. 161 (SFAS 161), "Disclosures about Derivative Instruments and Hedging Activities." SFAS 161 amends and expands the disclosure requirements of SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities," and is effective for fiscal years beginning after November 15, 2008. We do not expect the adoption of SFAS 161 will have a material impact on our results of operations or financial condition.

In May 2008, the FASB issued Staff Position FSP APB 14-1 (FSP APB 14-1), "Accounting for Convertible Debt Instruments That May Be Settled in Cash upon Conversion (Including Partial Cash Settlement)." FSP APB 14-1 requires companies that have issued convertible debt that may be settled wholly or partly in cash when converted, to account for the debt and equity components separately. The value assigned to the bond liability is the estimated value of a similar bond without the conversion feature as of the issuance date. The difference between the proceeds for the convertible debt and the amount reflected as a bond liability is recorded as additional paid-in-capital. Interest expense is recorded using the issuer's comparable debt rate. FSP APB 14-1 will be effective for us beginning June 1, 2009 (fiscal 2010) and will require retrospective application. We continue to review the impact of FSP APB 14-1 on our financial statements, however, we are currently estimating, based on the outstanding convertible notes at May 31, 2008, the implementation of FSP APB 14-1 will result in a reduction of our convertible notes of approximately $95,000, an increase in capital surplus of approximately $62,000 and an increase in deferred taxes of approximately $33,000. In addition, we expect the implementation of FSP APB 14-1 will reduce our diluted earnings per share by $0.12 to $0.15 per share in fiscal 2010.

Reclassification

Certain amounts in the prior years' consolidated financial statements have been reclassified to conform to the current year's presentation.

2. Financing Arrangements

Revolving Credit Facility

On August 31, 2007, we amended our credit agreement dated August 31, 2006 (the "Credit Agreement") with various financial institutions, as lenders, and LaSalle Bank National Association, as administrative agent for the lenders (the "Amendment"). The Amendment increased our unsecured revolving credit amount to $250,000 from $140,000. Under certain circumstances, we may request an increase to the revolving commitment by an aggregate amount of up to $75,000, not to exceed $325,000 in total. The Amendment extended the term of our Credit Agreement from August 31, 2010 to August 31, 2011. The Amendment also modified the borrowing rate of the Credit Agreement and borrowings now bear interest at the London Interbank Offered Rate ("LIBOR") plus 100 to 225 basis points based on certain financial measurements. In March 2008, a second amendment to the Credit Agreement modified the borrowing rate to LIBOR plus 100 to 237.5 basis points based on certain financial measurements. There were no borrowings outstanding under this facility at May 31, 2008.

Short-term borrowing activity under our revolving credit facilities during fiscal 2008, 2007 and 2006 was as follows:

	For the Year Ended May 31,
	2008			2007		2006

Recourse debt

During the fourth quarter of fiscal 2008, we retired $13,000 of our 8.39% notes due May 15, 2011 for $12,578. The gain from this transaction was $422 and is recorded in gain (loss) from extinguishment of debt on the consolidated statements of operations.

During February 2008, we completed the sale of $250,000 of convertible notes, consisting of $137,500 aggregate principal amount of 1.625% convertible senior notes due 2014 and $112,500 aggregate principal amount of 2.25% convertible senior notes due 2016 (together, the "Notes") in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. Interest under the Notes is payable semiannually on March 1 and September 1, beginning September 1, 2008.

Holders may convert their Notes based on a conversion rate of 28.1116 shares of our common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of $35.57 per share, only under the following circumstances: (i) during any calendar quarter beginning after March 31, 2008 (and only during such calendar quarter) if, as of the last day of the preceding calendar quarter, the closing price of our common stock for at least 20 trading days in a period of 30 consecutive trading days ending on the last trading day of such preceding calendar quarter is more than 130% of the applicable conversion price per share of common stock on the last day of such preceding calendar quarter; (ii) during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of notes of the applicable series for each day of that period was less than 98% of the product of the closing price of our common stock and the then applicable conversion rate; (iii) if a designated event or similar change of control transaction occurs; (iv) upon specified corporate transactions; or (v) beginning on February 1, 2014, in the case of the 2014 notes, or February 1, 2016, in the case of the 2016 notes, and ending at the close of business on the business day immediately preceding the applicable maturity date.

Upon conversion, a holder of the Notes will receive, in lieu of common stock, an amount in cash equal to the lesser of (i) $1,000 and (ii) the conversion value of a number of shares of our common stock equal to the conversion rate. If the conversion value exceeds the principal amount, we will also deliver at our election, cash or common stock or a combination thereof having a value equal to such excess amount.

The Notes are senior, unsecured obligations and rank equal in right of payment with all of our existing and future unsecured and unsubordinated expenses. Costs associated with this transaction of approximately $6,028 are being amortized on a pro-rata basis over a six- and eight-year period.

In connection with the issuance of the Notes, we entered into convertible note hedge transactions, (note hedges) with respect to our common stock with Merrill Lynch Financial Markets, Inc. (hedge provider). The note hedges are exercisable solely in connection with any conversion of the Notes and provide for us to receive shares of our common stock from the hedge provider equal to the number of shares issuable to the holders of the Notes upon conversion. We paid $69,676 for the note hedges.

In addition, we entered into separate warrant transactions with Merrill Lynch Financial Markets, Inc. whereby we issued warrants to purchase 7,028,000 shares of our common stock at an exercise price of $48.83 per share. We received $40,114 from the sale of these warrants. The convertible note hedges and

2. Financing Arrangements (Continued)

warrant transactions are intended to reduce potential dilution to our common stock upon future conversion of the Notes and generally have the effect of increasing the conversion price of the Notes to approximately $48.83 per share.

Net proceeds from the Notes transaction after paying expenses were approximately $214,410 and were used to repay the balance outstanding under our unsecured revolving credit facility, to pay for the net cost of the note hedges and warrant transactions and for general corporate purposes.

On February 1, 2006, we completed the sale of $150,000 principal amount of convertible senior notes. The notes are due on February 1, 2026 unless earlier redeemed, repurchased or converted, and bear interest at 1.75% payable semiannually on February 1 and August 1. Costs associated with this transaction of approximately $4,875 are being amortized over a seven-year period. Net proceeds from this transaction were $145,125 and were used in part to repurchase $25,000 of accounts receivable which had been sold under our former accounts receivable securitization facility, to repay $25,000 outstanding under our secured revolving credit facility and to purchase for $11,232 aviation equipment which was subject to an operating lease.

A holder may convert the notes into shares of common stock based on a conversion rate of 33.9789 shares per $1,000 principal amount of notes, which is equivalent to an initial conversion price of approximately $29.43 per share, under the following circumstances: (i) during any calendar quarter beginning after March 31, 2006 (and only during such calendar quarter), if, as of the last day of the preceding calendar quarter, the closing price of our common stock for at least 20 trading days in a period of 30 consecutive trading days ending on the last trading day of such preceding calendar quarter is more than 120% of the applicable conversion price per share of common stock on the last day of such preceding calendar quarter; (ii) during the five business day period after any five consecutive trading day period in which the "trading price" per $1,000 principal amount of notes for each day of that period was less than 98% of the product of the closing price of our common stock and the then applicable conversion rate; (iii) upon a redemption notice; (iv) if a designated event or similar change of control transaction occurs; (v) upon specified corporate transactions; or (vi) during the ten trading day period ending at the close of business on the business day immediately preceding the stated maturity date on the notes. Upon conversion, we will have the right to deliver, in lieu of shares of our common stock, cash or a combination of cash and shares of common stock, at our option, in an amount per note equal to the applicable conversion rate multiplied by the applicable stock price.

We may redeem for cash all or a portion of the notes at any time on or after February 6, 2013 at specified redemption prices. Holders of the notes have the right to require us to purchase for cash all or any portion of the notes on February 1, 2013, 2016 and 2021 at a price equal to 100% of the principal amount of the notes plus accrued interest and unpaid interest, if any, to the purchase date. The notes are senior, unsecured obligations and rank equal in right of payment with all other unsecured and unsubordinated indebtedness.

The mortgage loan due August 1, 2015 is secured by our Wood Dale, Illinois facility. At May 31, 2008, the net book value of our Wood Dale, Illinois facility is $14,427.

2. Financing Arrangements (Continued)

We are subject to a number of covenants under our financing arrangements, including restrictions which 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. The aggregate amount of long-term recourse debt maturing during each of the next five fiscal years is $200 in 2009, $200 in 2010, $42,108 in 2011, $0 in 2012 and $0 in 2013. Our long-term recourse debt was estimated to have a fair value of approximately $417,000 at May 31, 2008. The fair value was determined using available market information.

Non-recourse debt

During the third quarter of fiscal 2008, we retired non-recourse debt that was secured by an aircraft which was sold during the third quarter of fiscal 2008. The outstanding principal amount for this non-recourse debt was $19,748 and was retired for $20,375. The net loss from this transaction was $627 and is recorded in gain (loss) on extinguishment of debt on the consolidated statement of operations

On May 31, 2008, our total non-recourse debt balance is $39,402 and is secured by four aircraft with a net book value of $56,949. The aggregate amount of long-term non-recourse debt maturing during each of the next five fiscal years is $20,212 in 2009, $2,462 in 2010, $2,658 in 2011, $2,860 in 2012 and $9,274 in 2013.

3. 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 this 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 under the plan expire ten years from the date of grant and are exercisable in either four or five equal annual increments commencing one year after the date of grant. We issue new common stock upon the exercise of stock options. In addition to stock options, the Stock Benefit Plan also provides for the issuance of restricted stock awards and performance-based restricted stock awards, as well as for the granting of stock appreciation units; however, to date, no stock appreciation units 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 the Company. Restricted stock typically vests over periods of three to ten years from date of grant. Restricted stock grants may be performance-based with vesting to occur over periods of one to ten years after the grant is earned. All restricted stock 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 terminates employment for any reason other than death, retirement or disability or if we terminate employment for cause. A total of 5,237,000 shares have been granted under the Stock Benefit Plan since its inception, and as of May 31, 2008, awards representing 3,696,000 shares were available for future grant under the Stock Benefit Plan.

3. Stock-Based Compensation (Continued)

Effective June 1, 2006, we adopted SFAS No. 123(R), "Share-based Payment," using the modified prospective method of transition. Under SFAS No. 123(R), compensation expense is recognized for stock option grants made after May 31, 2006 and for the unvested portion of outstanding stock options that were granted prior to the adoption of SFAS No. 123(R). Compensation cost is measured based on the grant date fair value of the award and recognized on a straight line basis over the vesting period.

Prior to the adoption of SFAS No. 123(R), we accounted for stock-based compensation in accordance with Accounting Principles Board Opinion No. 25 ("APB 25"), "Accounting for Stock Issued to Employees," and SFAS No. 123, "Accounting for Stock-Based Compensation". Under APB 25, no compensation expense was recognized for stock option grants, and accordingly share-based compensation related to stock options granted prior to June 1, 2006 was included as pro forma disclosure in the consolidated financial statements.

Stock Options

On April 11, 2006, our Board of Directors approved the acceleration of the vesting of all unvested stock options. As a result of this action, stock options representing approximately 679,000 shares that were scheduled to vest in fiscal 2007, 2008 and 2009 became fully exercisable effective May 1, 2006. The accelerated vesting enabled us to reduce the amount of compensation expense that would otherwise be required to be recognized in our consolidated statements of operations with respect to these options upon the adoption of SFAS No. 123(R). The aggregate expense that was eliminated as a result of the acceleration was approximately $1,800. The acceleration resulted in a non-cash, one-time pre-tax stock compensation expense of $362 in the fourth quarter of fiscal 2006.

During fiscal 2008 and fiscal 2007, we granted stock options representing 88,000 shares and 100,000 shares, respectively. No stock options were granted during fiscal 2006 other than reload options, which resulted from the exercise of original stock options granted in prior years. Effective May 1, 2006, the reload provision was eliminated from substantially all outstanding stock option arrangements.

The weighted average fair value of stock options granted during fiscal 2008, 2007 and 2006 was $13.46, $11.93 and $3.71, 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
	2008		2007		2006
Risk-free interest rate	4.9	%	5.0	%	4.3	%
Expected volatility of common stock	43.1	%	58.7	%	34.1	%
Dividend yield	0.0	%	0.0	%	0.0	%
Expected option term in years	4.0		4.0		1.0

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 over the expected option term.

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 and return on capital, or the Company's stock price achieving a certain level over a period of time. After the shares are granted, the restrictions are released over a three to seven year period. During fiscal 2008, 2007 and 2006, we granted 35,000, 459,000 and 438,000 restricted shares, respectively, under this program.

In addition to the performance-based restricted stock awards, we also granted a total of 20,000 restricted shares to members of the Board of Directors during fiscal 2008. These shares vest over a three-year period.

The fair value of restricted shares is the market value of our common stock on the date of grant. Amortization expense related to all restricted shares during fiscal 2008, 2007 and 2006 was $5,943, $3,458 and $3,690 respectively.

Restricted share activity during the fiscal year ended May 31, 2008 is as follows (shares in thousands):

	Number of Shares		Weighted Average Fair Value on Grant Date

As of May 31, 2006, unearned compensation related to restricted shares was included in unearned restricted stock awards, a separate component of stockholders' equity. Upon the adoption of SFAS No. 123(R), the balance was reclassified to capital surplus. As of May 31, 2008, we had $11,970 of

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. The 2007 rights plan replaced a shareholder rights plan that expired on August 6, 2007.

On June 20, 2006 our Board of Directors authorized us to purchase up to 1,500,000 shares of our common stock on the market. This action superseded our previous stock repurchase plan which had remaining authorization to purchase 1,255,000 shares. During fiscal 2008, we purchased 321,700 shares of our common stock on the open market at an average price of $29.61.

4. Income Taxes

Our pre-tax income was substantially from domestic activities. The provision for income taxes on continuing operations includes the following components:

		For the Year Ended May 31,
		2008		2007		2006
Current:
	Federal	$	25,900	$	6,863	$	1,355
	State		1,200		700		900

			27,100		7,563		2,255
Deferred			13,243		20,411		8,433

		$	40,343	$	27,974	$	10,688

The deferred tax provision results primarily from differences between financial reporting and taxable income arising from inventory and depreciation.

Income tax payable at May 31, 2008 and 2007 was $14,523 and $2,101, respectively, and is included in accrued liabilities on the consolidated balance sheet.

The provision for income taxes on continuing operations differs from the amount computed by applying the U.S. federal statutory income tax rate of 35% for fiscal 2008, 2007 and 2006 to income before taxes, for the following reasons:

		For the Year Ended May 31,
		2008			2007			2006
Provision for income taxes at the federal statutory rate		$	40,631		$	30,597		$	16,279
	Tax benefit on exempt earnings from export sales		—			(2,916	)		(5,806	)
	Tax benefits on domestic production activities		(1,558	)		(167	)		—
	State income taxes, net of federal benefit and refunds		770			455			585
	Other		500			5			(370	)

Provision for income taxes on continuing operations		$	40,343		$	27,974		$	10,688

In October of 2004, the American Jobs Creation Act of 2004 (the "Act") was signed into law and included a number of Federal income tax reforms, including the phase-out of tax benefits on earnings from export sales.

4. Income Taxes (Continued)

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:

		May 31,
		2008			2007
Deferred tax assets-current attributable to:
	Inventory costs	$	15,973		$	24,162
	Employee benefits		(1,051	)		(878	)
	Allowance for doubtful accounts		2,043			1,293
	Advanced billings and other		1,338			936

	Total deferred tax assets-current	$	18,303		$	25,513

Deferred tax assets-noncurrent attributable to:
	Postretirement benefits	$	10,768		$	8,366
	Alternative minimum tax carryforwards, NOL carryforwards and foreign tax credit carryforwards		—			1,063
	Bond hedge		24,311			—

	Total deferred tax assets-noncurrent	$	35,079		$	9,429

	Total deferred tax assets	$	53,382		$	34,942

Deferred tax liabilities attributable to:
	Depreciation	$	(49,609	)	$	(43,031	)
	Leveraged leases		(5,813	)		(6,518	)
	Intangible assets		(7,633	)		—
	Unrealized gain on available for sale securities		(35	)		—

	Total deferred tax liabilities	$	(63,090	)	$	(49,549	)

Net deferred tax liabilities		$	(9,708	)	$	(14,607	)

As of May 31, 2008, 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, the nature of certain of our deferred tax assets, our expectations for continued future earnings and the scheduled reversal of deferred tax liabilities, primarily related to depreciation.

5. 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.

Under the provisions of Emerging Issues Task Force Issue No. 04-08, "The Effect of Contingently Convertible Instruments on Diluted Earnings per Share" ("EITF No. 04-08"), we are required to use the

5. Earnings Per Share (Continued)

"if converted" method set forth in SFAS No. 128, "Earnings Per Share," 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.

The following table provides a reconciliation of the computations of basic and diluted earnings per share information for each of the years in the three-year period ended May 31, 2008 (shares in thousands).

		For the Year Ended May 31,
		2008			2007			2006

	Weighted average common shares outstanding—diluted		43,745			43,309			38,852

Earnings per share—diluted:
	Earnings from continuing operations	$	1.77		$	1.42		$	0.96
	Loss from discontinued operations, net of tax		(0.01	)		(0.02	)		(0.02	)

	Earnings per share—diluted	$	1.76		$	1.40		$	0.94

At May 31, 2008, 2007 and 2006, respectively, options to purchase 78,000, 31,000 and 1,200,000 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.

6. Employee Benefit Plans

We have defined contribution and defined benefit plans covering substantially all full-time domestic employees and certain employees in The Netherlands.

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. 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, 2008 was 4.90%. 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 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 commence 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 the fourth quarter of fiscal 2001, we terminated the plan for any new members of the Board of Directors elected after May 31, 2001.

We also provide supplemental pension benefits for certain executives and key employees to supplement benefits provided by the cash balance plan.

Effective May 31, 2007, we adopted the provisions of SFAS No. 158, "Employers' Accounting for Defined Benefit Pension and Other Postretirement Plans". SFAS No. 158 requires employers to recognize the overfunded or underfunded status of a defined benefit pension or other postretirement plan as an asset or liability in its statement of financial position, recognize changes in that funded status in the year in which the changes occur through comprehensive income and measure a plan's assets and its obligations that determine its funded status as of the end of the employer's fiscal year. We have historically measured the plan assets and liabilities as of our balance sheet date.

Prior to the adoption of SFAS No. 158, a minimum pension liability adjustment was required when the actuarial present value of accumulated plan benefits exceeded plan assets and accrued pension liabilities. During fiscal 2007, we reduced the minimum pension liability by $3,104, and $1,921, net of tax, was reported as a component of comprehensive income.

Assumptions

The assumptions used in accounting for the Company's plans are estimates of factors including, among other things, the amount and timing of future benefit payments. The following table presents the key assumptions used in the measurement of the Company's benefit obligations:

		May 31,
		2008		2007
Domestic plans:
	Discount rate	6.45	%	6.05	%
	Rate of compensation increase	3.50		3.50
		May 31,
		2008		2007
Non-domestic plans:
	Discount rate	6.10	%	5.10	%
	Rate of compensation increase	3.00		3.00

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

		For the Year Ended May 31,
		2008		2007		2006
Domestic plans:
	Discount rate	6.05	%	6.40	%	5.40	%
	Rate of compensation increase	3.50		3.50		3.00
	Expected long-term return on plan assets	8.50		8.50		8.50
Non-domestic plans:
	Discount rate	5.10	%	4.75	%	4.25	%
	Rate of compensation increase	3.00		3.00		3.00
	Expected long-term return on plan assets	6.50		6.50		6.50

The discount rate was determined by projecting the plan's 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. Constraints were applied with respect to callability and credit quality. In addition, 3% of the bonds were deemed outliers due to questionable pricing information and consequently were excluded from consideration.

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
	2008		2007		Target Asset Allocation
Equity securities	59	%	67	%	45–75	%
Fixed income securities	22		21		25–55	%
Other (fund-of funds hedge fund)	19		12		0–20	%

	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. 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 investments in fund-of funds hedge funds.

The assets of the non-domestic plan are invested in compliance with local laws and regulations and are comprised of insurance contracts and 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.

Cash Flow

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

		Fiscal Year
		2009			2010			2011			2012			2013			2014 to 2018
Estimated pension benefits		$	7,127		$	5,441		$	5,425		$	5,546		$	5,573		$	29,231

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 $2,000 to $4,000 during fiscal 2009.

Additional Information

The estimated amounts for our plans that will be amortized from accumulated other comprehensive income into expense over the next fiscal year are as follows:

Amortization of net actuarial loss	$	736

Amortization of prior service cost	$	140

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 $1,427 and $1,370 as of May 31, 2008 and 2007, 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. Effective May 31, 2007, we adopted the provisions of SFAS No. 158 for this plan resulting in an increase to accumulated comprehensive loss of $465, net of tax.

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. Company contributions vest on a pro-rata basis during the first three years of employment. We also provide supplemental profit sharing benefits for certain executives and key employees to supplement the benefits provided by the defined contribution plan. Expense charged to results of operations for Company matching contributions, including profit sharing contributions, was $8,666 in fiscal 2008, $5,501 in fiscal 2007 and $4,216 in fiscal 2006 for these plans.

7. Acquisitions

On January 12, 2007, we acquired substantially all of the assets of Reebaire Aircraft, Inc. ("Reebaire"), a regional airframe maintenance, repair and overhaul facility located in Hot Springs, Arkansas. This acquisition increases our regional maintenance, repair and overhaul capacity in North America. The purchase price was $11,800 and was paid in cash.

On April 2, 2007, we acquired Brown International Corporation ("Brown"), a privately held defense contractor that provides engineering, design, manufacturing and systems integration services. Brown operates as part of our Structures and Systems segment. The purchase price was approximately $26,700 and was paid in cash.

On December 3, 2007, we acquired Summa Technology, Inc. ("Summa"), a leading provider of high-end sub-systems and precision machining, fabrication, welding and engineering services. Summa operates as part of our Structures and Systems segment. The purchase price was approximately $71,000 and was paid in cash.

On March 5, 2008, we acquired Avborne Heavy Maintenance, Inc. ("Avborne") and a related entity. Avborne is an independent provider of aircraft heavy maintenance checks, modifications, installations and painting services to commercial airlines, international cargo carriers and major aircraft leasing companies. The purchase price was approximately $40,000 and included a cash payment of $15,000 and the assumption of a $25,000 industrial revenue bond. Avborne operates as part of our Maintenance, Repair and Overhaul segment.

We have made a preliminary purchase price allocation for the Summa and Avborne acquisitions and are in the process of obtaining final valuations for the acquired net assets.

8. Aircraft Joint Ventures

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 are purchased with cash contributions by the members of the companies and debt financing provided to the limited liability companies on a limited recourse basis.

8. Aircraft Joint Ventures (Continued)

Twenty-nine aircraft were held in the joint ventures at May 31, 2008. 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 2008, 2007 and 2006, we were paid $232, $1,115 and $574, 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.

Summarized financial information for these limited liability companies is as follows:

		For the Year Ended May 31,
		2008		2007		2006
Statement of operations information:
	Sales	$	54,424	$	81,626	$	28,857
	Income before provision for income taxes		14,237		16,877		3,314
				May 31,

Balance sheet information:
	Assets			$	320,093	$	117,185
	Debt				233,662		80,425
	Members' capital				80,299		31,603

During the second quarter of fiscal 2008, an aircraft held by a joint venture, which was previously consolidated because we were the primary beneficiary of the joint venture, was sold. The minority interest related to the gain on the sale was approximately $2,400 and is recorded as an increase to cost of sales in the consolidated statement of operations.

9. Equipment on Long-Term Lease

In fiscal 2005, we entered into a series of ten-year agreements with Mesa to provide supply chain services for their fleet of CRJ 700/900, ERJ 145 and CRJ 200 regional jets. As part of the agreements, we purchased from the customer approximately $58,400 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 10 years to a 30% residual value.

10. Commitments and Contingencies

On October 3, 2003, we entered into a sale-leaseback transaction whereby the Company sold and leased back a facility located in Garden City, New York. The lease is classified as an operating lease in accordance with SFAS No. 13 "Accounting for Leases". Net proceeds from the sale of the facility were $13,991 and the cost and related accumulated depreciation of the facility of $9,472 and $4,595, respectively,

were removed from the consolidated balance sheet. The gain realized on the sale of $9,114 has been deferred and is being amortized over the 20-year lease term in accordance with SFAS No. 13. The unamortized balance of the deferred gain as of May 31, 2008 is $7,071 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 as well as aviation equipment under agreements that are classified as operating leases that expire at various dates through 2034. Under the terms of one of the facility lease agreements, we are entitled to receive rent credits as we increase the space we occupy. During fiscal 2008, 2007 and 2006, we received $1,000, $700 and $1,700, respectively, of such rent credits and in accordance with SFAS No. 13, we are treating the rent credits as lease incentives, which are being amortized over the term of the lease. Future minimum payments under all operating leases at May 31, 2008 are as follows:

	Future Minimum Payments

During the first quarter of fiscal 2008, we completed a sale-leaseback transaction with a financial institution to finance an aircraft under a capital lease. Proceeds were approximately $12,880.

10. 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, 2008 was approximately $18,032.

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.

11. Discontinued Operations

During the third quarter of fiscal 2007, we decided to exit our non-core industrial turbine business based in Frankfort, New York. Net assets of the business were approximately $4,600 at May 31, 2008 and consisted of $2,300 of accounts receivable, $800 of inventory, $1,800 of net property, plant and equipment and $300 of accounts payable.

Revenues and pre-tax operating loss for fiscal years 2008, 2007 and 2006 for the discontinued operations are summarized as follows:

	For the Year Ended May 31,
	2008			2007			2006
Revenues	$	6,104		$	7,778		$	11,766
Pre-tax operating loss	$	(925	)	$	(1,212	)	$	(1,015	)

12. Gain on Sale of Product Line

During the first quarter of fiscal 2007, we sold substantially all assets, subject to certain liabilities, of a product line within our Structures and Systems segment. Proceeds from the sale were $6,567 and the net carrying value of the assets sold was $1,209, resulting in a gain on sale of product line of $5,358. The gain on this transaction has been classified as a component of operating income in accordance with SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets."

13. Impairment Charges

During the first quarter of fiscal 2007, we recorded an impairment charge related to certain engine parts in the amount of $4,750. These parts were acquired prior to September 11, 2001. The fiscal 2007 impairment charge was triggered by our decision to pursue the liquidation of this inventory. We made the decision to recognize the impairment due to the impact of persistently high fuel costs and reduced demand for these parts, as well as to better align human and physical resources with higher potential opportunities in the rapidly growing Aviation Supply Chain segment. We had previously recorded impairment charges of $5,360 during the fourth quarter of fiscal 2003 and $75,900 during the second quarter of fiscal 2002 related to engine and airframe parts and whole engines.

Other Impairment and Gain on Extinguishment of Debt

During the first quarter of fiscal 2007, we restructured the lease and non-recourse debt on a wholly-owned wide-body aircraft. This aircraft was originally purchased prior to September 11, 2001. As a result of the restructuring of the lease and debt, we recorded a $2,927 gain on extinguishment of debt. Further, we decided to offer this aircraft for sale and recorded a $2,902 impairment charge to reduce the carrying value of the aircraft to its estimated net realizable value. This aircraft was sold during the third quarter of fiscal 2008.

14. Other Noncurrent Assets

Our portion of the revenue from this program is expected to exceed $300,000 through fiscal 2015, based on sales projections of the A400M. As of May 31, 2008, we have incurred approximately $43,000 of costs associated with the engineering and development of the cargo system and have capitalized these costs in accordance with SOP 81-1 "Accounting for Performance of Construction—Type and Certain Production—Type Contracts." Sales and related cost of sales will be recognized on the units of delivery method.

15. Business Segment Information

Segment Reporting

We report our activities in four business segments: Aviation Supply Chain; Maintenance, Repair and Overhaul; Structures and Systems; and Aircraft Sales and Leasing.

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 expenses and assets 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 reportable 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, 2008. 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, 2008, 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, 2008 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The Company's Common Stock is listed on the New York Stock Exchange ("NYSE") under the ticker symbol "AIR". On October 29, 2007, our Chief Executive Officer certified to the NYSE pursuant to Rule 303A.12(a) that, as of the date of that certification, he was not aware of any violation by the Company of the NYSE's Corporate Governance listings standards.

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 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based on our assessment, management concluded that the Company maintained effective internal control over financial reporting as of May 31, 2008.

The scope of management's assessment of the effectiveness of internal control over financial reporting includes all of our Company's consolidated subsidiaries except for Summa and Avborne, businesses acquired by our Company on December 3, 2007 and March 5, 2008, respectively. Our Company's consolidated net sales for the year-ended May 31, 2008 were $1,384,919 of which Summa and Avborne represented $67,309. Our Company's consolidated total assets as of May 31, 2008 were $1,362,010, of which Summa and Avborne represented $126,957.

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, 2008, based on criteria established in 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 effectiveness of 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 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, 2008, based on criteria established in Internal Control—Integrated Framework issued by COSO.

The scope of management's assessment of the effectiveness of internal control over financial reporting as of May 31, 2008 includes all of the Company's subsidiaries except for Summa Technology, Inc. (Summa) and Avborne Heavy Maintenance, Inc. (Avborne), businesses acquired by the Company on December 3, 2007 and March 5, 2008, respectively. The Company's consolidated net sales for the year-ended May 31, 2008 were $1,384,919 of which Summa and Avborne represented $67,309. The Company's consolidated total assets as of May 31, 2008 were $1,362,010, of which Summa and Avborne represented $126,957. Our audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over the financial reporting of Summa and Avborne.

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, 2008 and 2007, and the related consolidated statements of operations, stockholders' equity and cash flows for each of the years

in the three-year period ended May 31, 2008, and our report dated July 10, 2008 expressed an unqualified opinion on those consolidated financial statements.

AAR CORP.

Performance Restricted Stock Agreement

(“Agreement”)

Subject to the provisions of the AAR CORP. Stock Benefit Plan (“Plan”), the terms of which are hereby incorporated by reference herein, and in consideration of the agreements of the Grantee herein provided, AAR CORP., a Delaware corporation (“Company”), hereby grants to the Grantee a performance restricted stock award (“Award”), effective (“Date of Award”), in the number of shares of common stock (“Common Stock”) of the Company, $1.00 par value (“Award Shares”) set forth in the Company’s notification of Award letter dated subject to the forfeiture and nontransferability provisions hereof and the other terms and conditions set forth herein:

1. The Award is conditioned upon the acceptance by the Grantee of the terms hereof by confirming acceptance of the Award on Smith Barney’s web site (www.benefitaccess.com). If such acceptance has not occurred within 30 days from the date of the notification of award letter, the Award referenced herein shall expire unless the acceptance date is extended in writing signed by the Company.

2. Restrictions. The Grantee represents that he is accepting the Award Shares without a view toward distribution of said Shares and that he will not sell, assign, transfer, pledge or otherwise encumber the Award Shares during the period commencing on the Date of Award and ending with respect to any specific shares of stock on the date restrictions applicable to such shares are released pursuant to this Agreement (“Restrictive Period”).

3. Release of Restrictions. Subject to the provisions of paragraph 3 below, the restrictions described in 1 above shall be released with respect to 20% of the Award shares on , 40% of the Award shares on and the

balance of the unreleased Award shares on , except as follows (the first two releases to be rounded down to the nearest whole share):

(a) If the Grantee’s employment with the Company terminates by reason of death or Disability occurring on or after the Date of Award and on or before the third anniversary date thereof, the Restrictive Period shall terminate as to the difference between half the total number of Award Shares and those Shares previously released. The remaining shares shall be forfeited and returned to the Company.

(b) If the Grantee’s employment with the Company is terminated by reason of death or Disability after the third anniversary of the Date of Award, the Restrictive Period shall immediately terminate as to all of the Award Shares not previously released.

(c) If the Grantee’s employment is terminated by reason of Retirement prior to the last day of the Restrictive Period, the Restrictive Period shall terminate in accordance with the restriction release schedule set forth above as to the Award Shares not previously released.

(d) If the Grantee’s employment with the Company terminates prior to the last day of the Restrictive Period for any reason other than death, Disability or Retirement, the Grantee shall forfeit and return to the Company all Award Shares not previously released from the restrictions of Section 2 hereof.

(e) If at any time prior to release from restrictions hereunder, Grantee, without the Company’s express written consent, directly or indirectly, alone or as a member of a partnership, group, or joint venture or as an employee, officer, director, or 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 from time to time or at any time during the Grantee’s term of employment, the Grantee shall forfeit and return all Award Shares not previously released from the restrictions of Section 2 hereof.

4. Change in Control. In the event of a Change in Control of the Company, whether or not such change has the prior written approval of the Continuing Directors, the Restrictive Period shall terminate as to all Award Shares not previously released.

5. Change in Outstanding Shares. In the event of any change in the outstanding shares of Common Stock by reason of any stock dividend or split, recapitalization, merger, consolidation, combination or exchange of shares or other similar corporate change, the Award Shares shall be treated in the same manner in any such transaction as other shares of Common Stock. Any additional shares of stock received by 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.

6. Rights of Grantee. As the holder of the Award Shares, Grantee is entitled to all of the rights of a stockholder of AAR CORP. with respect to any of the Award Shares, when issued, including, but not limited to, the right to receive dividends declared and payable since the Date of Award.

7. Shares. In aid of the restrictions set forth in paragraph 2, electronic book shares on the records of the Transfer Agent, together with a suitably executed stock power signed by the Grantee, shall be held by a nominee of the Company for the account of Grantee until such restrictions lapse pursuant to the terms hereof, or such

Shares are forfeited to the nominee of the Company as provided by the Plan or this Agreement. The Grantee shall be entitled to shares representing the Award Shares as to which such restrictions have terminated, and the Company agrees to issue such shares in electronic form on the records of the Transfer Agent. Upon request by Grantee, the Transfer Agent will transfer such shares in electronic form to the Grantee’s broker for the Grantee’s account or issue certificates in the name of the Grantee representing the Award shares for which restrictions have been released.

8. Legend. The Company may, in its discretion, place a legend or legends on any electronic shares or certificates representing Award Shares issued to the Grantee that the Company believes is required to comply with any law or regulation.

9. Committee Powers. The Committee may subject the Award Shares to such conditions, limitations or restrictions as the Committee determines to be necessary or desirable to comply with any law or regulation or with the requirements of any securities exchange. At any time during the Restrictive Period, the Committee may reduce or terminate the Restrictive Period otherwise applicable to all or any portion of the Award Shares.

10. Withholding Taxes. Upon the Taxable Date(s) applicable to the release of Award share restrictions, Smith Barney will automatically withhold the appropriate number of shares (based on the NYSE closing price on the date of release) from the Award shares being released to satisfy applicable withholding requirements, including those arising under state and federal income tax laws prior to any unlegended shares being released into the Grantee’s account at the Transfer Agent.

11. Postponement of Distribution. Notwithstanding anything herein to the contrary, the distribution of any portion of the Award Shares shall be subject to action by the Board taken at any time in its sole discretion (i) to effect, amend or maintain any necessary registration of the Plan or the Award Shares distributable in satisfaction of this Award under the Securities Act of 1933, as amended, or the securities laws of any applicable jurisdiction, (ii) to permit any action to be taken in order to (a) list such Award Shares on a stock exchange if the Common Stock is then listed on such exchange or (b) comply with restrictions or regulations incident to the maintenance of a public market for its Shares of Common Stock, including any rules or regulations of any stock exchange on which the Award Shares are listed, or (iii) to determine that such Award Shares and the Plan are exempt from such registration or that no action of the kind referred to in (ii)(b) above needs to be taken; and the Company shall not be obligated by virtue of 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. 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.

(b) Capitalized terms used herein and not defined herein will have the meaning set forth in the Plan.

(Summa) and Avborne Heavy Maintenance, Inc. (Avborne), businesses acquired by the Company on December 3, 2007 and March 5, 2008, respectively. Our audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over the financial reporting of Summa and Avborne.
