Notes to Condensed Consolidated Financial Statements

November 30, 2011

(Unaudited)

(Dollars in thousands, except per share amounts)

Note 1 — Basis of Presentation

AAR CORP. and its subsidiaries are referred to herein collectively as “AAR,” “Company,” “we,” “us,” and “our,” unless the context indicates otherwise. The accompanying condensed consolidated financial statements include the accounts of AAR and its subsidiaries after elimination of intercompany accounts and transactions.

We have prepared these statements without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The condensed consolidated balance sheet as of May 31, 2011 has been derived from audited financial statements. To prepare the financial statements in conformity with U.S. generally accepted accounting principles, management has made a number of estimates and assumptions relating to the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Certain information and note disclosures, normally included in comprehensive financial statements prepared in accordance with U.S. generally accepted accounting principles, have been condensed or omitted pursuant to such rules and regulations of the SEC. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our latest annual report on Form 10-K.

In the opinion of management, the condensed consolidated financial statements reflect all adjustments (which consist only of normal recurring adjustments) necessary to present fairly the condensed consolidated financial position of AAR CORP. and its subsidiaries as of November 30, 2011, the condensed consolidated statements of income for the three- and six-month periods ended November 30, 2011 and 2010, its cash flows for the six-month periods ended November 30, 2011 and 2010 and the condensed consolidated statement of changes in equity for the six-month period ended November 30, 2011. The results of operations for such interim periods are not necessarily indicative of the results for the full year.

Note 2 — Revenue Recognition

Sales and related cost of sales for product sales are recognized upon shipment of the product to the customer. Our standard terms and conditions provide that title passes to the customer when the product is shipped to the customer. Sales of certain defense products are recognized upon customer acceptance, which includes transfer of title. Under the majority of our expeditionary airlift services contracts, we are paid and record as revenue a fixed daily amount per aircraft for each day an aircraft is available to perform airlift services. In addition, we are paid and record as revenue an amount which is based on number of hours flown. Sales from services and the related cost of services are generally recognized when customer-owned material is shipped back to the customer. We have adopted this accounting policy because at the time the customer-owned material is shipped back to the customer, all services related to that material are complete as our service agreements generally do not require us to provide services at customer sites. Furthermore, serviced units are typically shipped to the customer immediately upon completion of the related services. Sales and related cost of sales for certain long-term manufacturing contracts and certain large airframe maintenance contracts 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

(Dollars in thousands, except per share amounts)

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.

Included in accounts receivable as of November 30, 2011 and May 31, 2011, are $46,406 and $28,867, respectively, of unbilled accounts receivable related to a defense supply chain support agreement. These unbilled accounts receivable relate to costs we have incurred on parts that were requested and accepted by our customer to support the program. These costs have not been billed by us because the customer has not issued the final paperwork necessary to allow for billing.

In addition to the unbilled accounts receivable, included in Other on the condensed consolidated balance sheet as of November 30, 2011 and May 31, 2011, are $18,121 and $19,404, respectively, of costs in excess of amounts billed for the same defense supply chain support agreement. We expect to recover costs in excess of amounts billed through future billings over the life of the program.

Note 3 — Accounting for Stock-Based Compensation

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

We measure share-based compensation based on the fair value of the award at the grant date, and recognize the cost of share-based awards over the applicable service period, which is generally the vesting period. Performance-based restricted stock compensation is recognized over the applicable service period and based on the level of achievement that is considered probable.

During the six-month periods ended November 30, 2011 and 2010, we granted stock options representing 162,281 shares and 708,970 shares, respectively.

The weighted average fair value of stock options granted during the six-month periods ended November 30, 2011 and 2010 was $11.64 and $7.98, 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:

	Six Months Ended
	November 30,
	2011		2010
Risk-free interest rate	1.5	%	1.8	%
Expected volatility of common stock	45.8	%	47.0	%
Dividend yield	1.0	%	0.0	%
Expected option term in years	5.7		5.8

The total fair value of stock options that vested during the six-month periods ended November 30, 2011 and 2010 was $3,776 and $2,275, respectively. The total intrinsic value of stock options exercised during the six-month periods ended November 30, 2011 and 2010 was $3,323 and $87, respectively. The tax benefit realized from stock options exercised during the six-month periods ended November 30, 2011 and 2010 was $595 and $15, respectively.

On April 12, 2011, we entered into an agreement with various financial institutions, as lenders and Bank of America, N.A., as administrative agent for the lenders (as amended on October 13, 2011, the “Credit Agreement”) providing for an unsecured revolving credit facility that we can draw upon for general corporate purposes. The revolving commitment was originally $400,000 and on October 13, 2011 was increased to $580,000. Under certain circumstances, we may request an increase to the revolving commitment by an aggregate amount of up to $100,000, not to exceed $680,000 in total. The Credit Agreement expires on April 12, 2016. Borrowings under the Credit Agreement bear interest at the offered Eurodollar Rate (defined as the British Bankers Association LIBOR Rate) plus 125 to 225 basis points based on certain financial measurements if a Eurodollar Rate

As of November 30, 2011 and May 31, 2011, the long-term debt and equity component (recorded in capital surplus, net of income tax benefit) consisted of the following:

	November 30,			May 31,
	2011			2011
Long-term debt:
Principal amount	$	268,380		$	268,380

Net carrying amount	$	238,649		$	232,147

Equity component, net of tax	$	74,966		$	74,966

The discount on the liability component of long-term debt is being amortized using the effective interest method based on an effective rate of 8.48% for our 1.75% convertible notes; 6.82% for our 1.625% convertible notes and 7.41% for our 2.25% convertible notes. For our 1.75% convertible notes, the discount is being amortized through February 1, 2013, which is the first put date for those notes. For our 1.625% and 2.25% convertible notes, the discount is being amortized through their respective maturity dates of March 1, 2014 and March 1, 2016.

As of November 30, 2011 and 2010, for each of our convertible note issuances, the “if converted” value does not exceed its principal amount.

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

	Three Months Ended				Six Months Ended
	November 30,				November 30,
	2011		2010		2011		2010

Note 8 — Derivative Instruments and Hedging Activities

We are exposed to interest rate risk associated with fluctuations in interest rates on our variable rate debt. During the first quarter of fiscal 2012, we entered into two derivative financial instruments in order to manage our variable interest rate exposure over a medium- to long-term period. In June, we entered into a floating-to-fixed interest rate swap to hedge interest on $50,000 of notional principal balance under our revolving credit agreement. Also in June, we entered into an interest rate cap agreement on $50,000 of notional principal interest under our revolving credit agreement.

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

We classify the derivatives as assets or liabilities on the balance sheet. Accounting for the change in fair value of the derivatives is a function of whether the instrument qualifies for, and has been designated as, a hedging relationship, and the type of hedging relationship. As of November 30, 2011, all of our derivative instruments were classified as cash flow hedges. The fair value of the interest rate swap and interest cap agreements represents the difference in the present values of cash flows calculated at the contracted interest rates and at current market interest rates at the end of the reporting period.

The fair value of the Company’s interest rate derivatives are classified as Level 2 in the fair value hierarchy. Level 2 refers to fair values estimated using significant other observable inputs including quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. At November 30, 2011, the fair value of the Company’s interest rate derivatives was recorded as follows:

		Derivative		Derivative
		Assets		Liabilities
	Balance Sheet Classification	November 30, 2011		November 30, 2011
Derivatives designated as hedging instruments:

Interest rate cap	Long-term assets	$	685	$	—
Interest rate swap	Long-term liabilities	$	—	$	(3,144	)

We include gains and losses on the derivative instruments in other comprehensive income. We recognize the gains and losses on our derivative instruments as an adjustment to interest expense in the period the hedged interest payment affects earnings. The impact of the interest rate swap and interest cap agreement on the condensed consolidated statement of income for the three- and six-month periods ended November 30, 2011 was as follows:

	Three Months Ended			Six Months Ended
	November 30, 2011			November 30, 2011
Gain (loss) recognized in other comprehensive income — effective portion	$	(221	)	$	(2,736	)

Gain (loss) reclassified from accumulated other comprehensive income into income	$	—		$	—

Gain (loss) recognized in income — ineffective portion	$	—		$	—

We expect minimal gain or loss to be reclassified into earnings within the next 12 months.

Note 9 — Earnings per Share

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

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

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

The following table provides a reconciliation of the computations of basic and diluted earnings per share information for the three- and six-month periods ended November 30, 2011 and 2010.

At November 30, 2011 and 2010, respectively, stock options to purchase 267,000 and 449,000 shares of common stock were outstanding, but were not included in the computation of diluted earnings per share because the exercise price of each of these options was greater than the average market price of the common shares during the interim periods then ended.

Note 10 — License Fees

In June 2011, we entered into a ten-year agreement with Unison Industries to be the exclusive worldwide aftermarket distributor for Unison’s electrical components, sensors, switches and other systems for aircraft and industrial uses (the “Agreement”). The Agreement is expected to generate approximately $600,000 in revenues for the Company over its ten-year term. In connection with the agreement, we agreed to pay Unison Industries $20,000 for the exclusive distribution rights with $7,000 paid in June 2011, and $1,300 payable by January 31 of each calendar year beginning in January 2012 through 2021.

In June 2011, we recorded an asset of $16,513, representing the $7,000 license fee paid in June 2011 and the present value of the future obligation for the license fees under the Agreement. This item is

The current portion of the deferred payments is recorded in Accrued liabilities and the long-term portion is included in Other liabilities and deferred income on the condensed consolidated balance sheet.

Note 11 — Acquisition

On October 11, 2011, we acquired Airinmar Holdings Limited (“Airinmar”), an international provider of aircraft component repair management services. Airinmar operates as part of our Aviation Supply Chain segment. Total consideration is estimated to be $43,500, which includes $23,200 cash paid at closing, and a potential earn-out payment of $20,300. The potential earn-out payment is based upon Airinmar achieving certain EBITDA (earnings before interest, taxes, depreciation and amortization) levels over a two-year period, as well as retaining certain key customers. In accordance with accounting principles generally accepted in the United States of America, a liability of $20,300 was recognized as an estimate of the acquisition date fair value of the earn-out and is included in Other non-current liabilities on our condensed consolidated balance sheet as of November 30, 2011. Any change in the fair value of the earn-out subsequent to the date of acquisition will be recognized in earnings.

We have made a preliminary purchase price allocation for the Airinmar acquisition and are in the process of obtaining final valuations for the acquired assets and liabilities. The preliminary purchase price allocation follows. We have omitted the pro-forma statement of income information for Airinmar because it is not material.

Note 12 —Aircraft Portfolio

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

Aircraft Owned through Joint Ventures

As of November 30, 2011, the Company had ownership interests in 20 aircraft with joint venture partners. As of November 30, 2011, our equity investment in the 20 aircraft owned with joint venture partners was approximately $36,228 and is included in Investment in joint ventures on the condensed consolidated balance sheet. 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. Under the terms of servicing agreements with certain of the

Note 13 — Discontinued Operations

During the third quarter of fiscal 2011, we decided to exit our Amsterdam component repair facility, a business which was reported in our Aviation Supply Chain segment. We are currently evaluating a number of strategic alternatives associated with the business unit, including the sale of the unit. The aggregate carrying value of the unit is approximately $14,300 and we expect to recover the carrying value.

lightweight cargo containers for commercial airlines from facilities in Norway and China. The purchase price of the acquisition was $280,000, and was funded initially through our revolving credit facility. The businesses will operate as part of our Structures and Systems segment.

Note 15 — Business Segment Information

We report our activities in four business segments: Aviation Supply Chain; Government and Defense Services; Maintenance, Repair and Overhaul; and Structures and Systems.

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 principally to the commercial aviation market. We also offer customized inventory supply chain management programs. Sales also include the sale and lease of commercial aircraft and jet engines and technical and advisory services. Cost of sales consists principally of the cost of product, direct labor, overhead (primarily indirect labor, facility cost and insurance) and the cost of lease revenue (primarily depreciation and insurance).

Sales in the Government and Defense Services segment are derived from the sale of new and overhauled engine and airframe parts and components, customized performance-based logistics programs, expeditionary airlift services, aircraft modifications and engineering, design, and integration services to our government and defense customers. Cost of sales consists principally of the cost of the product (primarily aircraft and engine parts), direct labor, overhead and aircraft maintenance costs.

Sales in the Maintenance, Repair and Overhaul segment are principally derived from aircraft maintenance, including painting, 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 requirements for a mobile and agile force, 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.

In the second quarter of fiscal 2012, we recognized losses on certain programs at our precision machining business which operates as part of our Structures and Systems segment. The losses on certain programs include $2,157 of out-of-period expenses primarily related to an inventory adjustment, with $921 originating in fiscal 2011 and $1,236 originating in the first quarter of fiscal 2012. This adjustment was not material to any of the related periods.

The accounting policies for the segments are the same as those described in Note 1 of Notes to Consolidated Financial Statements included in our annual report on Form 10-K for the year ended May 31, 2011. 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.

General Overview

We report our activities in four business segments: Aviation Supply Chain; Government and Defense Services; Maintenance, Repair and Overhaul; and Structures and Systems. The table below sets forth consolidated sales for our four business segments for the three- and six-month periods ended November 30, 2011 and 2010.

Beginning with our first quarter of fiscal 2011, we saw the early signs of a recovery in demand for products and services offered to our commercial customers. This recovery followed a period when many U.S. and foreign air carriers reduced fleet capacity, deferred maintenance spending, reduced inventory levels and reduced demand for parts support and maintenance activities. The commercial aviation recovery gained momentum during fiscal 2011 as air carriers expanded their fleets and replenished inventory levels. In addition, we won several new programs supporting our commercial customers, which also contributed to the sales recovery for that market segment. During the first six months of fiscal 2012, sales to commercial customers increased 24.1% compared to the prior year and represented 50.7% of consolidated sales. The increase was driven by strong demand at our Aviation Supply Chain and MRO businesses, and the sale of four aircraft from our aircraft portfolio. Sales growth to commercial customers during the first six months of fiscal 2012 occurred against a backdrop of global economic uncertainty, including the debt crisis in Europe, relatively high oil prices, and recent airline bankruptcies. We are monitoring these events and their potential impact on our commercial customers.

During the first six months of fiscal 2012, sales to global government and defense customers increased 3.6% compared to the prior year and for the six months ended November 30, 2011 represented 49.3% of consolidated sales. The increase was driven by sales increases at our AAR Airlift and our defense logistics business, each operating within our Government and Defense Services segment. Although our airlift business today contracts only with the U.S. Department of Defense, we are targeting other U.S. governmental agencies, as we believe our airlift services will be in greater demand as the U.S. broadens its interest in non-military activities, including nation building. Notwithstanding sales growth to date to our government and defense customers, defense funding is currently facing pressures due to the overall economic environment and competing federal budget priorities. In addition, in November, it was announced that the Super Committee, a committee of twelve Congressmen, had failed to agree on a deficit reduction plan for the U.S. federal budget. The failure of the Super Committee to reach agreement may result in automatic cuts to the U.S. federal budget, a portion of which may be allocated to the U.S. DoD budget. We are closely monitoring discussions related to the DoD budget and its potential impact on sales to our government and defense customers.

Results of Operations

Three-Month Period Ended November 30, 2011

Consolidated sales for the second quarter ended November 30, 2011 increased $35,380 or 8.0% compared to the prior year period. Sales to commercial customers increased 10.8% compared to the prior year due to strong demand for supply chain services and the sale of two aircraft from our wholly-owned aircraft portfolio, while sales to government and defense customers increased 5.4% reflecting sales increases at our airlift and defense logistics businesses.

In the Aviation Supply Chain segment, sales increased $32,027 or 28.8% compared to the prior year due to the sale of two aircraft for approximately $15,700 from our aircraft sales and leasing portfolio and strength at our parts supply businesses, which benefited from recent investments in assets. Gross profit in the Aviation Supply Chain segment increased $6,384 or 33.0%, and the gross profit margin percentage increased to 17.9% from 17.4% in the prior year due to the mix of products sold. During the

second quarter, we acquired Airinmar Holdings Limited (“Airinmar”), a leading provider of repair management services. Airinmar operates as part of the Aviation Supply Chain segment and the impact of this acquisition on second quarter sales and earnings from continuing operations was negligible.

In the Government and Defense Services segment, sales increased $7,983 or 5.9% compared to the prior year. The sales increase reflects growth in program business at the Company’s defense logistics business and strength at AAR Airlift. Gross profit decreased $196 or 0.8% and the gross profit margin percentage decreased to 16.8% from 18.0% in the prior year due to lower margins at AAR Airlift reflecting reduced aircraft availability.

In the Maintenance, Repair and Overhaul segment, sales decreased $7,160 or 7.2% versus the prior year due to lower sales at our engineering services business. Gross profit increased $1,174 or 9.6%, and the gross profit margin percentage increased to 14.7% from 12.4% in the prior year primarily due to operational efficiencies and increased volume at our MRO airframe centers.

In the Structures and Systems segment, sales increased $2,530 or 2.6% over the prior year due to slightly higher sales at our mobility products and cargo businesses. Gross profit in the Structures and Systems segment decreased $3,884 or 21.7% and the gross profit margin percentage decreased to 14.3% from 18.7% in the prior year primarily due to losses on certain programs and start-up costs on new programs at our precision machining business. The losses on certain programs include $2,157 of out-of-period expenses primarily related to an inventory adjustment, with $921 originating in fiscal 2011 and $1,236 originating in the first quarter of fiscal 2012. This adjustment was not material to any of the related periods.

Selling, general and administrative expenses increased $2,260 or 5.5%, which included $1,375 of transaction-related expenses for acquisitions announced during the second quarter. Earnings from aircraft joint ventures decreased $2,270 as the prior year included earnings from the sale of an aircraft from our joint venture portfolio. Operating income decreased $1,052 or 3.0% compared with the prior year primarily due to the reduction in the gross profit margin. Net interest expense increased $31 or 0.4% compared to the prior year and our effective income tax rate was 34.5% in the second quarter of fiscal 2012 compared to 35.0% last year.

Net income was $17,532 compared to $16,814 in the prior year due to the factors discussed above.

Six-Month Period Ended November 30, 2011

Consolidated sales for the six months ended November 30, 2011 increased $110,277 or 13.1% compared to the prior year period. Sales to commercial customers increased 24.1% compared to the prior year due to strong demand for supply chain and MRO services and the sale of four aircraft from our wholly-owned aircraft portfolio, while sales to government and defense customers increased 3.6% reflecting sales increases at our airlift and defense logistics businesses, offset by lower sales at our mobility products division.

In the Aviation Supply Chain segment, sales increased $86,635 or 40.9% compared to the prior year due to the sale of four aircraft for approximately $49,000 from our aircraft sales and leasing portfolio and strength at our parts supply businesses, which benefited from the improved commercial airline environment and recent investments of assets. Gross profit in the Aviation Supply Chain segment increased $12,443 or 32.3%, and the gross profit margin percentage decreased to 17.1% from 18.2% in the prior year due to the impact of the sale of the four aircraft. During the second quarter, we acquired Airinmar Holdings Limited (“Airinmar”), a leading provider of repair management services. Airinmar operates as part of the Aviation Supply Chain segment and the impact of this acquisition on second quarter sales and earnings from continuing operations was negligible.

In the Government and Defense Services segment, sales increased $28,652 or 10.9% compared to the prior year. The sales increase reflects growth in program business at the Company’s defense logistics business and strength at AAR Airlift. Gross profit increased $4,191 or 8.9% and the gross profit margin percentage decreased to 17.6% from 17.9% in the prior year reflecting slightly lower margins in the airlift business due to reduced aircraft availability.

In the Maintenance, Repair and Overhaul segment, sales increased $9,198 or 5.2% versus the prior year due to strong sales at our landing gear facility and share gains at our MRO facilities, partially offset by lower sales at our engineering services business. Gross profit increased $1,328 or 5.9%, and the gross profit margin percentage increased slightly to 12.8% from 12.7% in the prior year.

In the Structures and Systems segment, sales decreased $14,208 or 7.3% over the prior year due to the expected decline in the volume at our mobility products business, all of which occurred in our first quarter. Gross profit in the Structures and Systems segment decreased $9,645 or 27.1% and the gross profit margin percentage decreased to 14.4% from 18.4% in the prior year due to lower volume, the mix of products sold and losses on certain programs and start-up costs on new programs at our precision machining business.

Selling, general and administrative expenses increased $2,748 or 3.3%, which included $1,732 of transaction-related expenses announced for acquisitions announced during the second quarter. Earnings from aircraft joint ventures decreased $2,093 as the prior year included earnings from the sale of an aircraft from our joint venture portfolio. Operating income increased $3,476 or 5.4% compared with the prior year primarily due to the increase in sales, partially offset by a reduction in the profit margins. Net interest expense increased $172 or 1.2% compared to the prior year and our effective income tax rate was 34.5% compared to 35.0% last year.

Net income was $34,181 compared to $30,488 in the prior year due to the factors discussed above.

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 an unsecured credit facility, as well as a separate secured credit facility. We continually evaluate various financing arrangements, including the issuance of common stock and/or debt, which would allow us to improve our liquidity position and finance future growth on commercially reasonable terms. Our continuing ability to borrow from our lenders and issue debt and equity securities to the public and private markets in the future may be negatively affected by a number of factors, including the overall health of the credit markets, general economic conditions, airline industry conditions, geo-political events, and our operating performance. Our ability to generate cash from operations is influenced primarily by our operating performance and changes in working capital.

At November 30, 2011, our liquidity and capital resources included cash of $27,870 and working capital of $580,109. On April 12, 2011, we entered into an agreement with various financial institutions, as lenders and Bank of America, N.A., as administrative agent for the lenders (as amended on October 13, 2011, the “Credit Agreement”)

Table of Contents

providing for an unsecured revolving credit facility that we can draw upon for general corporate purposes. The revolving commitment was originally $400,000 and on October 13, 2011 was increased to $580,000. Under certain circumstances, we may request an increase to the revolving commitment by an aggregate amount of up to $100,000, not to exceed $680,000 in total. The Credit Agreement expires on April 12, 2016. Borrowings under the Credit Agreement bear interest at the offered Eurodollar Rate (defined as the British Bankers Association LIBOR Rate) plus 125 to 225 basis points based on certain financial measurements if a Eurodollar Rate loan, or at the offered fluctuating Base Rate plus 25 to 125 basis points based on certain financial measurements if a Base Rate loan.

Borrowings outstanding under the Credit Agreement at November 30, 2011 were $150,000, with $50,000 classified as short-term debt and $100,000 classified as long-term debt. There were also $11,366 of outstanding letters of credit which reduced the availability of this facility. We also have $3,521 available under a foreign line of credit.

In addition to our unsecured Credit Agreement, we have a $65,000 secured revolving credit facility with The Huntington National Bank (the “Huntington Loan Agreement”). Borrowings under the Huntington Loan Agreement are secured by aircraft and related engines and components owned by the Company. The Huntington Loan Agreement expires on April 23, 2015. Borrowings bear interest at LIBOR plus 325 basis points. As of November 30, 2011, $63,296 was outstanding under this agreement.

During the six-month period ended November 30, 2011, our cash flow from operations was $4,799 primarily as a result of net income and aggregate depreciation and amortization of $81,747, a reduction in equipment on long-term lease of $24,106 principally due to the sale of aircraft, and an increase in accounts payable of $20,860 supporting our investment in inventories. Uses of cash from operations during the six-month period ended November 30, 2011 included an increase to inventories of $60,218 primarily to support supply chain customers and our airlift operations. We also made a payment to Unison (see Note 10 of Notes to Condensed Consolidated Financial Statements), invested in aircraft overhauls and continued to invest in the A400M program which is reported in Other (see “Critical Accounting Policies and Significant Estimates — Program Development Costs” below).

During the six-month period ended November 30, 2011, our investing activities used $74,325 of cash principally as a result of capital expenditures of $55,153, which mainly represents helicopters and other equipment purchased to support growth and improve operating performance in our Government and Defense Services segment, and the acquisition of Airinmar, net of cash acquired of $19,522.

During the six-month period ended November 30, 2011, our financing activities provided $39,486 of cash primarily due to an increase in short- and long-term borrowings of $63,155, offset by a reduction in borrowings of $10,878, payment of a capital lease obligation of $6,742, cash dividends paid of $6,052 and the purchase of treasury stock of $3,659.

Critical Accounting Policies and Significant Estimates

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

Allowance for Doubtful Accounts

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

Goodwill and Other Intangible Assets

Under accounting standards for goodwill and other intangible assets, goodwill and other intangible assets deemed to have indefinite lives are not amortized, but are subject to annual impairment tests. The Company reviews and evaluates its goodwill and indefinite life intangible assets for potential impairment at a minimum annually, on May 31, or more frequently if circumstances indicate that impairment is possible. We use a two-step process to evaluate goodwill for impairment. In the first step, we compare the fair value of each reporting unit with the carrying value of the reporting unit, including goodwill. We estimate the fair value of each reporting unit using a valuation technique based on a multiple of earnings or discounted cash flows. If the estimated fair value of the reporting unit is less than the carrying value of the reporting unit, we would be required to complete a second step to determine the amount of goodwill impairment. In the second step, we would determine an implied fair value of the reporting unit’s goodwill by allocating the reporting unit’s fair value to all of the assets and liabilities other than goodwill. We then would compare the implied fair value of goodwill to the carrying amount and recognize the difference as an impairment charge.

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

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.

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. Reductions in demand for certain of our inventories or declining market values, as well as

Table of Contents

differences between actual results and the assumptions utilized by us when determining the market value of our inventories, could result in the recognition of impairment charges in future periods.

Revenue Recognition

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

We are required to test for impairment of long-lived assets whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable from its undiscounted cash flows. When applying accounting standards addressing impairment to equipment on or available for lease, we have utilized certain assumptions to estimate future undiscounted cash flows, including current and future lease rates, lease terms, residual values and market conditions and trends impacting future demand. Differences between actual results and the assumptions utilized by us when determining undiscounted cash flows could result in future impairments of aircraft and engines which are currently being leased or are available for lease. During the fourth quarter of fiscal 2011, we recorded a $5,355 pre-tax impairment charge to reduce the carrying value of an aircraft held for sale to its fair value.

Program Development Costs

In June 2005, we announced that our Cargo Systems business was selected to provide cargo handling systems for the new Airbus A400M Military Transport Aircraft (“A400M”). Our portion of the revenue from this program is expected to exceed $300,000 through fiscal 2021, based on sales projections of the A400M. As of November 30, 2011, we have capitalized, net of reimbursements, $86,031 of costs associated with the engineering and development of the cargo system. Sales and related cost of sales will be recognized on the units of delivery method. In determining the recoverability of the capitalized program development costs, we have 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, 2011, 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

Table of Contents

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.

Forward-Looking Statements

This report contains certain forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on beliefs of our 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 Part II, Item 1A under the heading “Risk Factors” and to those set forth under Part I, Item 1A in our Annual Report on Form 10-K for the year ended May 31, 2011. 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.

Item 3 – Quantitative and Qualitative Disclosures About Market Risk

Our market risks relate to changes in interest rates. The interest rate on borrowings under our unsecured revolving credit agreement is floating and, therefore, is subject to fluctuation. In order to manage the risk associated with changes in interest rates on borrowings under this agreement, we entered into derivative agreements to hedge a portion of the cash flows associated with the facility.

As of November 30, 2011, we had a floating to fixed interest rate swap agreement with an aggregate notional amount of $50,000 that effectively converted the $50,000 of notional principal under the credit agreement from floating-rate debt to fixed-rate debt. At November 30, 2011 we were in a liability position for this interest rate swap, the fair value of which was $3,144.

Also as of November 30, 2011, we had an interest rate cap agreement for the purpose of limiting future exposure to interest rate risk on $50,000 of notional principal outstanding under the unsecured revolving credit agreement. Under this agreement, we made a premium payment totaling $1,750 to cap the interest rate for the five-year term of the agreement. At November 30, 2011, the interest rate cap had a fair value of $685.

Item 4 – Controls and Procedures

As required by Rules 13a-15(e) and 15d-15(e) of the Exchange Act, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of November 30, 2011. 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 November 30, 2011.

There were no changes in our internal control over financial reporting during the second quarter ended November 30, 2011 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
