Notes to Condensed Consolidated Financial Statements

(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 February 29, 2012, the condensed consolidated statements of income for the three- and nine-month periods ended February 29, 2012 and February 28, 2011, its cash flows for the nine-month periods ended February 29, 2012 and February 28, 2011 and the condensed consolidated statement of changes in equity for the nine-month period ended February 29, 2012.  The results of operations for such interim periods are not necessarily indicative of the results for the full year.

Beginning with our third quarter of fiscal 2012, we are no longer treating the operating results of our Amsterdam component repair business as a discontinued operation.  During the period, we made the decision to retain the operation after considering the results of our sales process and reviewing strategic alternatives for the business.  The operating results for the Amsterdam business have been reported in continuing operations for all periods presented and are not material to our financial position or results of operations.

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 and performance-based logistics programs 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.

Included in accounts receivable as of February 29, 2012 and May 31, 2011, are $35,771 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 February 29, 2012 and May 31, 2011, are $33,684 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, subject to vesting, is based on achievement of certain Company-wide financial goals or stock price targets.  The Stock Benefit Plan also provides for the grant of stock appreciation units and restricted stock units; however, to date, no such awards have been granted.

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.

(Dollars in thousands, except per share amounts)

During the nine-month periods ended February 29, 2012 and February 28, 2011, we granted stock options representing 162,281 shares and 720,970 shares, respectively.

The weighted average fair value of stock options granted during the nine-month periods ended February 29, 2012 and February 28, 2011 was $11.64 and $8.06, respectively.  The fair value of each stock option grant was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:

	Nine Months Ended
	February 29/28,
	2012		2011
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 following table summarizes stock option activity for the nine-month period ended February 29, 2012:

					Weighted
			Weighted		Average
	Number of		Average		Remaining	Aggregate
	Options		Exercise		Contractual	Intrinsic
	(in thousands)		Price		Life (years)	Value
Outstanding at May 31, 2011	1,994		$	18.56
Granted	162		$	28.96
Exercised	(335	)	$	20.00
Cancelled	(78	)	$	18.69
Outstanding at February 29, 2012	1,743		$	19.61	5.9	$	8,835
Exercisable at February 29, 2012	862		$	18.20	4.0	$	5,186

The total fair value of stock options that vested during the nine-month periods ended February 29, 2012 and February 28, 2011 was $3,827 and $2,275, respectively.  The total intrinsic value of stock options exercised during the nine-month periods ended February 29, 2012 and February 28, 2011 was $3,339 and $898, respectively.  The tax benefit realized from stock options exercised during the nine-month periods ended February 29, 2012 and February 28, 2011 was $533 and $146, respectively.  Expense charged to operations for stock options during the three-month periods ended February 29, 2012 and February 28, 2011 was $1,078 and $1,177, respectively.  Expense charged to operations for stock options during the nine-month periods ended February 29, 2012 and February 28, 2011 was $3,279 and $3,222, respectively.  As of February 29, 2012, we had $4,924 of unearned compensation related to stock options that will be amortized over an average remaining period of 1.0 years.

The fair value of restricted stock awards is the market value of our common stock on the date of grant.  Amortization expense related to restricted stock awards during the three-month periods ended February 29, 2012 and February 28, 2011 was $2,711 and $2,462, respectively.   Amortization expense related to restricted stock awards during the nine-month periods ended February 29, 2012 and February 28, 2011 was $6,635 and $6,245, respectively.

On January 23, 2012 we completed an offering of $175,000 aggregate principal amount of 7.25% Senior Notes due 2022 (the “Notes”).  The Notes were sold to qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and outside the United States to non-U.S. persons in accordance with Regulation S under the Securities Act.  The Notes were sold at a price equal to 98.268% if the principal amount thereof, for a yield to maturity of 7.5%.  The

net proceeds of the offering of the Notes were used to repay a portion of the borrowings under our revolving credit agreement incurred to fund our December 2011 acquisition of Telair® International GmbH and Nordisk Aviation Products AS from Teleflex Incorporated.

The Notes are governed by an Indenture dated as of January 23, 2012 (the “Indenture”) by and among AAR, certain subsidiary guarantors identified therein (the “Guarantors”) and U.S. Bank National Association, as trustee.

The Notes bear interest at a rate of 7.25% per year, payable semi-annually, in cash in arrears, on January 15 and July 15 of each year, commencing July 15, 2012.  The Notes will mature on January 15, 2022.  Prior to January 15, 2015, AAR may redeem up to 35% of the aggregate principal amount of the Notes with the net cash proceeds of certain equity offerings at a redemption price of 107.25% of the principal amount thereof, plus accrued and unpaid interest and additional interest, if any, to the redemption date.  At any time prior to January 15, 2017, AAR may redeem the Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus a make-whole premium, plus any accrued and unpaid interest and additional interest, if any, to the redemption date.  AAR may redeem the Notes at its option, in whole or in part, at any time on or after January 15, 2017, upon not less than 30 nor more than 60 days’ notice at the redemption prices (expressed as percentages of the principal amount to be redeemed) set forth below, plus any accrued and unpaid interest and additional interest, if any, to the redemption date if redeemed during the 12-month period beginning on January 15 of the years indicated below:

Year	Redemption Price
2017	103.625	%
2018	102.417	%
2019	101.208	%
2020 and thereafter	100.000	%

The Notes are unconditionally guaranteed, on a full, joint and several basis, by each of the Guarantors, which consist of all of our existing domestic subsidiaries.  The Notes and the guarantees are general unsecured senior obligations of AAR and the Guarantors, respectively, rank equally in right of payment with all existing and future senior debt of AAR and the Guarantors, as applicable, and are senior in right of payment to all future subordinated obligations of AAR or the Guarantors.  The Notes and the guarantees are effectively subordinated to secured debt of AAR and the Guarantors, respectively, to the extent of the value of the assets securing that debt.  In addition, the Notes are structurally junior to any debt or other liabilities of our nonguarantor subsidiaries.

The Indenture contains covenants that, amount other things, limit AAR’s and its Restricted Subsidiaries’ (as defined in the Indenture) abilities to (i) incur additional debt or sell preferred stock, (ii) pay dividends, redeem or repurchase stock or make other distributions, (iii) make certain investments, (iv) make other restricted payments and investments, (v) agree to or allow to exist restrictions on the ability to pay dividends or make other payments on its capital interests, (vi) create liens without granting equal and ratable liens to the holders of the Notes, (vii) enter into sale and leaseback transactions, (viii) merge, consolidate or transfer or dispose of substantially all of their assets, (ix) enter into certain types of transactions with affiliates and (x) sell assets.  These covenants are subject to a number of qualifications and limitations.  In addition, the Indenture limits AAR’s and the Restricted Subsidiaries’ abilities to engage in businesses other than businesses in which such companies are engaged on the date of issuance of the Notes and related businesses.

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, 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 loan, or at the offered fluctuating Base Rate plus 25 to 125 basis points based on certain financial measurements if a Base Rate loan.

During the second quarter of fiscal 2012, we sold an aircraft and the associated non-recourse debt of $3,252, which was due April 3, 2015, was assumed by the purchaser.  Also during the second quarter of fiscal 2012, we purchased our joint venture partner’s interest in a narrow-body aircraft.  In connection with this acquisition, we assumed $6,545 of non-recourse debt, which was paid in full on December 8, 2011.

During the first quarter of fiscal 2012, the non-recourse note due July 19, 2012 became fully recourse to the Company and is presented in the recourse portion of the table above.

During the nine-month period ended February 28, 2011, we repurchased $6,000 par value of our 2.25% convertible notes due March 1, 2016.  The notes were repurchased for $4,667 cash, and the gain of $97, after consideration of unamortized discount and debt issuance costs, is recorded in Gain on extinguishment of debt on the condensed consolidated statements of income.

At February 29, 2012, the face value of our long-term recourse debt was $628,720 and the estimated fair value was approximately $627,000.  The fair value of the Company’s long-term recourse debt is 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.

Convertible Notes

On June 1, 2009, we adopted a new accounting standard that clarifies the accounting for convertible debt instruments that may be settled wholly or partly in cash when converted, and requires convertible debt to be accounted for as two components: (i) a debt component which is recorded upon issuance at the estimated fair value of a similar straight-debt instrument without the debt-for-equity conversion feature; and (ii) an equity component that is included in capital surplus and represents the estimated fair value of the conversion feature at issuance.  The bifurcation of the debt and equity components results in a discounted carrying value of the debt component compared to the principal amount.  The discount is accreted to the carrying value of the debt component through interest expense over the expected life of the debt using the effective interest method.

As of February 29, 2012 and May 31, 2011, the long-term debt and equity component (recorded in capital surplus, net of income tax benefit) consisted of the following:

	February 29,			May 31,
	2012			2011
Long-term debt:
Principal amount	$	268,380		$	268,380
Unamortized discount	(26,384		)	(36,233		)
Net carrying amount	$	241,996		$	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 February 29, 2012 and February 28, 2011, 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				Nine Months Ended
	February 29/28,				February 29/28,
	2012		2011		2012		2011
Coupon interest	$	1,229	$	1,229	$	3,685	$	3,704
Amortization of deferred financing fees	189		189		565		566
Amortization of discount	3,346		3,098		9,848		9,149
Interest expense related to convertible notes	$	4,764	$	4,516	$	14,098	$	13,419

Subsequent Event

On March 9, 2012, we entered into a five (5) year full amortization term loan agreement with Development Bank of Japan Inc. (the “Loan Agreement”) under which we intend to borrow $50,000 on an unsecured basis to refinance indebtedness incurred to finance the acquisition of Telair and Nordisk.  Borrowings under the Loan Agreement bear interest at the offered Eurodollar Rate (defined as the British Bankers Association LIBOR Rate) plus 250 basis points.

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

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 February 29, 2012, 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.  At February 29, 2012, the fair value of the Company’s interest rate derivatives was recorded as follows:

		Derivative		Derivative
		Assets		Liabilities
	Balance Sheet Classification	February 29, 2012		February 29, 2012
Derivatives designated as hedging instruments:
Interest rate cap	Long-term assets	$	409	$	—
Interest rate swap	Long-term liabilities	$	—	$	(3,805	)

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 nine-month periods ended February 29, 2012 was as follows:

	Three Months Ended			Nine Months Ended
	February 29, 2012			February 29, 2012
Amount of pre-tax loss recorded in accumulated other comprehensive income (loss)	$	(937	)	$	(5,146	)
Amount of pre-tax loss reclassified from accumulated other comprehensive income (loss) to earnings	$	—		$	—
Amount of pre-tax loss recorded in earnings	$	—		$	—

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.

At February 29, 2012 and February 28, 2011, respectively, stock options to purchase 260,000 and 278,000 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 — Acquisitions

On December 2, 2011, we acquired Telair® International GmbH (“Telair”) and Nordisk Aviation Products, AS (“Nordisk”).  Telair is a leader in the design, manufacture and support of cargo loading systems for wide-body and narrow-body aircraft with established positions on the world’s most popular current and next-generation passenger and freighter aircraft.  Telair operates from facilities in Germany, Sweden and Singapore.  Nordisk designs and manufactures heavy duty pallets and lightweight cargo containers for commercial airlines from facilities in Norway and China.  The purchase price of the acquisition was approximately $293,000.  The businesses operate as part of our Structures and Systems segment.

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 February 29, 2012.  Any change in the fair value of the earn-out subsequent to the date of acquisition will be recognized in earnings.

We are continuing our review of our fair value estimate of assets acquired and liabilities assumed during the measurement period, which will conclude as soon as we receive the information we are seeking about facts and circumstances that existed as of the acquisition date, or learn that more information is not available.  This measurement period will not exceed one year from the acquisition date.  At the effective date of the acquisition, the assets acquired and liabilities assumed are generally required to be measured at fair value.

Our fair value estimate of assets acquired and liabilities assumed is pending completion of several elements, including the finalization of an independent appraisal and valuations of fair value of the assets acquired and liabilities assumed and final review by our management.  The primary areas that are not yet finalized relate to the fair value of accounts receivable, accounts payable, inventories, property and equipment, intangible assets, favorable or unfavorable contracts, operating leases or commitments, contingent liabilities and income and non-income related taxes.  Accordingly, there could be material adjustments to our consolidated financial statements, including changes in our depreciation and amortization expense related to the valuation of property and equipment and intangible assets acquired and their respective useful lives among other adjustments.

The final determination of the assets acquired and liabilities assumed will be based on the established fair value of the assets acquired and the liabilities assumed as of the acquisition date.  The excess of the purchase price over the fair value of net assets acquired is allocated to goodwill.  The final determination of the purchase price, fair values and resulting goodwill may differ significantly from what is reflected in these condensed consolidated financial statements.

Note 11 —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 February 29, 2012, the Company had ownership interests in 19 aircraft with joint venture partners.  As of February 29, 2012, our equity investment in the 19 aircraft owned with joint venture partners was approximately $37,008 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 12 — 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.

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.

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

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 nine-month periods ended February 29 and 28, 2012 and 2011.

During the first nine months of fiscal 2012, sales to commercial customers increased 27.1% compared to the prior year and represented 53.2% of consolidated sales.  Commercial sales growth during the first six months of fiscal 2012 was driven by strong organic growth in the Aviation Supply Chain and MRO businesses, whereas commercial sales growth in the most recent three month period was primarily driven by the Telair and Nordisk acquisitions.  Commercial sales growth during fiscal 2012 occurred against a backdrop of global economic uncertainty, including persistently high oil prices, recent bankruptcies in the aviation industry and the debt crisis in Europe. We are monitoring these events and their potential impact on our commercial customers.

During the first nine months of fiscal 2012, sales to global government and defense customers increased 2.0% compared to the prior year and for the nine months ended February 29, 2012 represented 46.8% of consolidated sales.  Defense funding is currently facing pressure due to U.S. budget deficit challenges. In August 2011, Congress enacted the Budget Control Act (BCA) of 2011 which reduces defense spending by $487 billion over a ten-year period starting in fiscal 2012. Under the BCA, an automatic sequestration process was triggered when the Super Committee, a committee of twelve Congressmen, failed to agree on a deficit reduction plan for the U.S. federal budget. The sequestration is scheduled to commence on January 2, 2013, absent legislative or other remedial action. Of the $1.2 trillion in reduced spending required by sequestration over the ten-year period beginning in fiscal year 2013, approximately $50 billion per year would be borne by the DoD.    Whether or not sequestration goes into effect, we expect the defense budget to be reduced. Although there may be opportunities for those business units within our Supply Chain and Maintenance, Repair and Overhaul segments that support the DoD, as a result of defense spending reductions, we expect our businesses that support the DoD within our Structures and Systems segment may be adversely affected.

Results of Operations

Three-Month Period Ended February 29, 2012

Consolidated sales for the third quarter ended February 29, 2012 increased $76,160 or 16.6% compared to the prior year period.  The increase in sales principally represents the inclusion of sales from Telair and Nordisk in the amount of $55,303.  Telair and Nordisk were acquired on December 2, 2011.

In the Aviation Supply Chain segment, sales increased $14,252 or 11.9% compared to the prior year.  The increase in sales was the result of strength at our parts supply businesses, which continues to benefit from investments made in assets to support commercial customers.  Gross profit in the Aviation Supply Chain segment increased $5,740, or 27.6% and the gross profit margin percentage increased to 19.8% from 17.3% in the prior year due to a favorable mix of inventories sold.

In the Government and Defense Services segment, sales decreased $13,620 or 9.2% compared to the prior year.  The sales decrease reflects a reduction in activity under one of the Company’s performance-based logistics program, as well as lower sales at AAR Airlift due to unfavorable aircraft availability. Gross profit decreased $6,497 or 25.3%, and the gross profit margin percentage declined to 14.3% from 17.4% due to lower volume in our defense logistics business, lower volume at AAR Airlift, and the impact of aircraft availability as compared to last year.

In the Maintenance, Repair and Overhaul segment, sales increased $3,997 or 3.7% due to increased airframe maintenance activities primarily due to share gains, partially offset by lower sales at our engineering services business.  Gross profit decreased $3,913 or 22.8%, and the gross profit margin percentage declined to 11.8% from 15.9% in the prior year primarily due to lower sales volume in our high-margin engineering services business.

In the Structures and Systems segment, sales increased $71,531 or 86.5% over the prior year.  The sales increase reflects the inclusion of Telair and Nordisk, which contributed $55,303 of revenue during the third quarter, as well as increased sales at our Mobility Products business due to an increase in production on a program.  Gross profit in the Structures and Systems segment increased $12,835 or 84.5%, and the gross profit percentage decreased slightly to 18.2% from 18.4%.

Selling, general and administrative expenses increased $7,199 or 16.3% and was primarily driven by selling, general and administrative expenses at Telair and Nordisk.  Operating income increased $1,039 or 3.0% due to the increase in sales, offset by a reduction in the consolidated gross profit margin percentage from 17.2% in the prior year to 16.3% this year.  Net interest expense increased $2,560 due to an increase in borrowings to fund the Telair and Nordisk acquisitions.

During the third quarter of fiscal 2012, our effective income tax rate was 18.8%, compared to 34.1% last year.  During the third quarter of this year, we recorded a $3,976 reduction in income tax expense, primarily relating to a reduction in the Company’s state income tax rate due to the implementation of state income tax planning strategies related to the Company’s corporate structure and the relocation of one of our significant businesses.  We expect our effective income tax rate to be approximately 34.5% in the fourth quarter of fiscal 2012.

Net income attributable to AAR was $20,663 compared to $17,918 in the prior year due to the factors discussed above.

Nine-Month Period Ended February 29, 2012

Consolidated sales for the nine months ended February 29, 2012 increased $184,366 or 14.0% compared to the prior year period.  Sales to commercial customers increased 27.1% compared to the prior year due to the inclusion of sales from Telair and Nordisk, strong demand for supply chain and MRO

26

services and the sale of four aircraft from our wholly-owned aircraft portfolio.  Sales to government and defense customers increased 2.0% reflecting sales increases at our airlift and defense logistics businesses.

In the Aviation Supply Chain segment, sales increased $98,816 or 28.6% 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 $19,066 or 31.4%, and the gross profit margin percentage increased to 18.0% from 17.6% in the prior year primarily due to the mix of inventories 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 sales and earnings was negligible.

In the Government and Defense Services segment, sales increased $15,032 or 3.7% compared to the prior year.  The sales increase primarily reflects growth in program business at the Company’s defense logistics business.  Gross profit decreased $2,306 or 3.2% and the gross profit margin percentage decreased to 16.5% from 17.7% in the prior year reflecting lower margins in the airlift business due to reduced aircraft availability.

In the Maintenance, Repair and Overhaul segment, sales increased $13,195 or 4.6% 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 decreased $2,585 or 6.5%, and the gross profit margin percentage decreased to 12.4% from 13.9% in the prior year due to lower sales of high margin engineering services.

In the Structures and Systems segment, sales increased $57,323 or 20.7% over the prior year due to the inclusion of sales from Telair and Nordisk.  Gross profit in the Structures and Systems segment increased $3,190 or 6.3% and the gross profit margin percentage decreased to 16.2% from 18.4% in the prior year due to 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 $8,765 or 6.7% and was primarily driven by selling, general and administrative expenses at Telair and Nordisk.  Operating income increased $6,580 or 6.8% due to the increase in sales, offset by a reduction in the consolidated gross profit margin percentage from 17.0% in the prior year to 16.1% this year.  Net interest expense increased $2,725 due to an increase in borrowings to fund the Telair and Nordisk acquisitions.

During the nine month period ended February 29, 2012, our effective income tax rate was 29.3%, compared to 34.7% last year.  During the third quarter of this year, we recorded a $3,976 reduction in income tax expense, primarily relating to a reduction in the Company’s state income tax rate due to the implementation of state income tax planning strategies related to the Company’s corporate structure and the relocation of one of our significant businesses.  We expect our effective income tax rate to be approximately 34.5% in the fourth quarter of fiscal 2012.

Net income attributable to AAR was $54,844 compared to $48,406 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

27

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 February 29, 2012, our liquidity and capital resources included cash of $59,294 and working capital of $504,403.  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, 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 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 February 29, 2012 were $300,000, with $200,000 classified as short-term debt and $100,000 classified as long-term debt. There were also $14,581 of outstanding letters of credit which reduced the availability of this facility.  We also have $3,607 available under a foreign lines 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 February 29, 2012, $60,504 was outstanding under this agreement.

On March 9, 2012, we entered into a five year full amortization term loan agreement with Development Bank of Japan Inc. (the “Loan Agreement”) under which we intend to borrow $50,000 on an unsecured basis to refinance indebtedness incurred to finance the acquisition of Telair and Nordisk.  Borrowings under the Loan Agreement bear interest at the offered Eurodollar Rate (defined as the British Bankers Association LIBOR Rate) plus 250 basis points.

During the nine-month period ended February 29, 2012, our cash flow from operations was $18,231 primarily as a result of net income and aggregate depreciation and amortization of $131,294, a reduction in equipment on long-term lease of $17,547 principally due to the sale of aircraft, and an increase in accounts payable of $9,408 supporting our investment in inventories.  Uses of cash from operations during the nine-month period ended February 29, 2012 included an increase to inventories of $56,955 primarily to support supply chain customers and our airlift operations.  We also made a $7,000 license fee payment to Unison, 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).

28

During the nine-month period ended February 29, 2012, our investing activities used $361,113 of cash principally as a result of capital expenditures of $62,702, 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 Telair, Nordisk and Airinmar, net of cash acquired of $298,087.

During the nine-month period ended February 29, 2012, our financing activities provided $343,892 of cash primarily due to an increase in both short- and long-term borrowings of $378,982 (see Note 7 of Notes to Consolidated Financial Statements), offset by a reduction in borrowings of $19,300, payment of a capital lease obligation of $6,763, cash dividends paid of $9,068 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.

29

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

Revenue Recognition

Certain supply chain management programs that we provide to our customers contain multiple elements or deliverables, such as program and warehouse management, parts distribution and maintenance and repair services.  We recognize revenue for each element or deliverable that can be identified as a separate unit of accounting at the time of delivery based upon the relative fair value of the products and services.  Sales and related cost of sales for certain long-term manufacturing contracts and certain large airframe maintenance contracts and performance-based logistics programs are recognized by the percentage of completion method, either based on the relationship of costs incurred to date to estimated total costs or the units of delivery method. In connection with these contracts and programs, we are required to make certain judgments and estimates 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 February 29, 2012, we have capitalized, net of reimbursements, $96,942 of costs associated with the engineering and development of the cargo system.  The Company is in negotiations with Airbus to recover amounts invested in the design and development of the A400M aircraft and to increase the per ship set selling price as a result of design changes initiated by Airbus.  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.

30

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 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 February 29, 2012, 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 February 29, 2012 we were in a liability position for this interest rate swap, the fair value of which was $3,805.

Also as of February 29, 2012, 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 February 29, 2012, the interest rate cap had a fair value of $409.

Revenues and expenses of our foreign operations are translated at average exchange rates during the year, and balance sheet accounts are translated at period end exchange rates.  Balance sheet translation adjustments are excluded from the results of operations and are recorded in stockholders’ equity as a component of accumulated other comprehensive loss.  A hypothetical 10 percent devaluation of foreign currencies against the U.S. dollar would impact pre-tax income by approximately $1,200 for the three-month period ended February 29, 2012.

31

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 February 29, 2012.  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 February 29, 2012.

There were no changes in our internal control over financial reporting during the third quarter ended February 29, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Accounting for Stock-Based Compensation

Accounting for Stock-Based Compensation

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, subject to vesting, is based on achievement of certain Company-wide financial goals or stock price targets.  The Stock Benefit Plan also provides for the grant of stock appreciation units and restricted stock units; however, to date, no such awards have been granted.

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 nine-month periods ended February 29, 2012 and February 28, 2011, we granted stock options representing 162,281 shares and 720,970 shares, respectively.

The weighted average fair value of stock options granted during the nine-month periods ended February 29, 2012 and February 28, 2011 was $11.64 and $8.06, respectively.  The fair value of each stock option grant was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:

	Nine Months Ended
	February 29/28,
	2012		2011
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 following table summarizes stock option activity for the nine-month period ended February 29, 2012:

					Weighted
			Weighted		Average
	Number of		Average		Remaining	Aggregate
	Options		Exercise		Contractual	Intrinsic
	(in thousands)		Price		Life (years)	Value
Outstanding at May 31, 2011	1,994		$	18.56
Granted	162		$	28.96
Exercised	(335	)	$	20.00
Cancelled	(78	)	$	18.69
Outstanding at February 29, 2012	1,743		$	19.61	5.9	$	8,835
Exercisable at February 29, 2012	862		$	18.20	4.0	$	5,186

The total fair value of stock options that vested during the nine-month periods ended February 29, 2012 and February 28, 2011 was $3,827 and $2,275, respectively.  The total intrinsic value of stock options exercised during the nine-month periods ended February 29, 2012 and February 28, 2011 was $3,339 and $898, respectively.  The tax benefit realized from stock options exercised during the nine-month periods ended February 29, 2012 and February 28, 2011 was $533 and $146, respectively.  Expense charged to operations for stock options during the three-month periods ended February 29, 2012 and February 28, 2011 was $1,078 and $1,177, respectively.  Expense charged to operations for stock options during the nine-month periods ended February 29, 2012 and February 28, 2011 was $3,279 and $3,222, respectively.  As of February 29, 2012, we had $4,924 of unearned compensation related to stock options that will be amortized over an average remaining period of 1.0 years.

The fair value of restricted stock awards is the market value of our common stock on the date of grant.  Amortization expense related to restricted stock awards during the three-month periods ended February 29, 2012 and February 28, 2011 was $2,711 and $2,462, respectively.   Amortization expense related to restricted stock awards during the nine-month periods ended February 29, 2012 and February 28, 2011 was $6,635 and $6,245, respectively.

Restricted share activity during the nine-month period ended February 29, 2012 was as follows:

	Number of		Weighted Average
	Shares		Fair Value
	(in thousands)		on Grant Date
Unvested at May 31, 2011	1,374		$	23.06
Granted	677		$	24.64
Vested	(325	)	$	26.71
Forfeited	(107	)	$	23.90
Unvested at February 29, 2012	1,619		$	22.92

During the nine-month period ended February 29, 2012, we granted a total of 45,000 restricted shares to members of the Board of Directors.  As of February 29, 2012 we had $19,577 of unearned compensation related to restricted shares that will be amortized to expense over a weighted average period of 2.3 years.

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 and performance-based logistics programs 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.

Included in accounts receivable as of February 29, 2012 and May 31, 2011, are $35,771 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 February 29, 2012 and May 31, 2011, are $33,684 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.

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 February 29, 2012, the condensed consolidated statements of income for the three- and nine-month periods ended February 29, 2012 and February 28, 2011, its cash flows for the nine-month periods ended February 29, 2012 and February 28, 2011 and the condensed consolidated statement of changes in equity for the nine-month period ended February 29, 2012.  The results of operations for such interim periods are not necessarily indicative of the results for the full year.

Beginning with our third quarter of fiscal 2012, we are no longer treating the operating results of our Amsterdam component repair business as a discontinued operation.  During the period, we made the decision to retain the operation after considering the results of our sales process and reviewing strategic alternatives for the business.  The operating results for the Amsterdam business have been reported in continuing operations for all periods presented and are not material to our financial position or results of operations.

Aircraft Portfolio

Note 11 —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 February 29, 2012, the Company had ownership interests in 19 aircraft with joint venture partners.  As of February 29, 2012, our equity investment in the 19 aircraft owned with joint venture partners was approximately $37,008 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 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.  For the nine-month periods ended February 29, 2012 and 2011, we were paid $500 and $635, 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 condensed 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:

Business Segment Information

Note 12 — 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.

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.

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

Earnings per Share

Earnings per Share

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 nine-month periods ended February 29, 2012 and February 28, 2011.

On January 23, 2012 we completed an offering of $175,000 aggregate principal amount of 7.25% Senior Notes due 2022 (the “Notes”).  The Notes were sold to qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and outside the United States to non-U.S. persons in accordance with Regulation S under the Securities Act.  The Notes were sold at a price equal to 98.268% if the principal amount thereof, for a yield to maturity of 7.5%.  The net proceeds of the offering of the Notes were used to repay a portion of the borrowings under our revolving credit agreement incurred to fund our December 2011 acquisition of Telair® International GmbH and Nordisk Aviation Products AS from Teleflex Incorporated.

The Notes are governed by an Indenture dated as of January 23, 2012 (the “Indenture”) by and among AAR, certain subsidiary guarantors identified therein (the “Guarantors”) and U.S. Bank National Association, as trustee.

The Notes bear interest at a rate of 7.25% per year, payable semi-annually, in cash in arrears, on January 15 and July 15 of each year, commencing July 15, 2012.  The Notes will mature on January 15, 2022.  Prior to January 15, 2015, AAR may redeem up to 35% of the aggregate principal amount of the Notes with the net cash proceeds of certain equity offerings at a redemption price of 107.25% of the principal amount thereof, plus accrued and unpaid interest and additional interest, if any, to the redemption date.  At any time prior to January 15, 2017, AAR may redeem the Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus a make-whole premium, plus any accrued and unpaid interest and additional interest, if any, to the redemption date.  AAR may redeem the Notes at its option, in whole or in part, at any time on or after January 15, 2017, upon not less than 30 nor more than 60 days’ notice at the redemption prices (expressed as percentages of the principal amount to be redeemed) set forth below, plus any accrued and unpaid interest and additional interest, if any, to the redemption date if redeemed during the 12-month period beginning on January 15 of the years indicated below:

Year	Redemption Price
2017	103.625	%
2018	102.417	%
2019	101.208	%
2020 and thereafter	100.000	%

The Notes are unconditionally guaranteed, on a full, joint and several basis, by each of the Guarantors, which consist of all of our existing domestic subsidiaries.  The Notes and the guarantees are general unsecured senior obligations of AAR and the Guarantors, respectively, rank equally in right of payment with all existing and future senior debt of AAR and the Guarantors, as applicable, and are senior in right of payment to all future subordinated obligations of AAR or the Guarantors.  The Notes and the guarantees are effectively subordinated to secured debt of AAR and the Guarantors, respectively, to the extent of the value of the assets securing that debt.  In addition, the Notes are structurally junior to any debt or other liabilities of our nonguarantor subsidiaries.

The Indenture contains covenants that, amount other things, limit AAR’s and its Restricted Subsidiaries’ (as defined in the Indenture) abilities to (i) incur additional debt or sell preferred stock, (ii) pay dividends, redeem or repurchase stock or make other distributions, (iii) make certain investments, (iv) make other restricted payments and investments, (v) agree to or allow to exist restrictions on the ability to pay dividends or make other payments on its capital interests, (vi) create liens without granting equal and ratable liens to the holders of the Notes, (vii) enter into sale and leaseback transactions, (viii) merge, consolidate or transfer or dispose of substantially all of their assets, (ix) enter into certain types of transactions with affiliates and (x) sell assets.  These covenants are subject to a number of qualifications and limitations.  In addition, the Indenture limits AAR’s and the Restricted Subsidiaries’ abilities to engage in businesses other than businesses in which such companies are engaged on the date of issuance of the Notes and related businesses.

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, 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 loan, or at the offered fluctuating Base Rate plus 25 to 125 basis points based on certain financial measurements if a Base Rate loan.

During the second quarter of fiscal 2012, we sold an aircraft and the associated non-recourse debt of $3,252, which was due April 3, 2015, was assumed by the purchaser.  Also during the second quarter of fiscal 2012, we purchased our joint venture partner’s interest in a narrow-body aircraft.  In connection with this acquisition, we assumed $6,545 of non-recourse debt, which was paid in full on December 8, 2011.

During the first quarter of fiscal 2012, the non-recourse note due July 19, 2012 became fully recourse to the Company and is presented in the recourse portion of the table above.

During the nine-month period ended February 28, 2011, we repurchased $6,000 par value of our 2.25% convertible notes due March 1, 2016.  The notes were repurchased for $4,667 cash, and the gain of $97, after consideration of unamortized discount and debt issuance costs, is recorded in Gain on extinguishment of debt on the condensed consolidated statements of income.

At February 29, 2012, the face value of our long-term recourse debt was $628,720 and the estimated fair value was approximately $627,000.  The fair value of the Company’s long-term recourse debt is 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.

Convertible Notes

On June 1, 2009, we adopted a new accounting standard that clarifies the accounting for convertible debt instruments that may be settled wholly or partly in cash when converted, and requires convertible debt to be accounted for as two components: (i) a debt component which is recorded upon issuance at the estimated fair value of a similar straight-debt instrument without the debt-for-equity conversion feature; and (ii) an equity component that is included in capital surplus and represents the estimated fair value of the conversion feature at issuance.  The bifurcation of the debt and equity components results in a discounted carrying value of the debt component compared to the principal amount.  The discount is accreted to the carrying value of the debt component through interest expense over the expected life of the debt using the effective interest method.

As of February 29, 2012 and May 31, 2011, the long-term debt and equity component (recorded in capital surplus, net of income tax benefit) consisted of the following:

	February 29,			May 31,
	2012			2011
Long-term debt:
Principal amount	$	268,380		$	268,380
Unamortized discount	(26,384		)	(36,233		)
Net carrying amount	$	241,996		$	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 February 29, 2012 and February 28, 2011, 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				Nine Months Ended
	February 29/28,				February 29/28,
	2012		2011		2012		2011
Coupon interest	$	1,229	$	1,229	$	3,685	$	3,704
Amortization of deferred financing fees	189		189		565		566
Amortization of discount	3,346		3,098		9,848		9,149
Interest expense related to convertible notes	$	4,764	$	4,516	$	14,098	$	13,419

Subsequent Event

On March 9, 2012, we entered into a five (5) year full amortization term loan agreement with Development Bank of Japan Inc. (the “Loan Agreement”) under which we intend to borrow $50,000 on an unsecured basis to refinance indebtedness incurred to finance the acquisition of Telair and Nordisk.  Borrowings under the Loan Agreement bear interest at the offered Eurodollar Rate (defined as the British Bankers Association LIBOR Rate) plus 250 basis points.

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

Derivative Instruments and Hedging Activities

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 February 29, 2012, 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.  At February 29, 2012, the fair value of the Company’s interest rate derivatives was recorded as follows:

		Derivative		Derivative
		Assets		Liabilities
	Balance Sheet Classification	February 29, 2012		February 29, 2012
Derivatives designated as hedging instruments:
Interest rate cap	Long-term assets	$	409	$	—
Interest rate swap	Long-term liabilities	$	—	$	(3,805	)

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 nine-month periods ended February 29, 2012 was as follows:

	Three Months Ended			Nine Months Ended
	February 29, 2012			February 29, 2012
Amount of pre-tax loss recorded in accumulated other comprehensive income (loss)	$	(937	)	$	(5,146	)
Amount of pre-tax loss reclassified from accumulated other comprehensive income (loss) to earnings	$	—		$	—
Amount of pre-tax loss recorded in earnings	$	—		$	—

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

Note 10 — Acquisitions

On December 2, 2011, we acquired Telair® International GmbH (“Telair”) and Nordisk Aviation Products, AS (“Nordisk”).  Telair is a leader in the design, manufacture and support of cargo loading systems for wide-body and narrow-body aircraft with established positions on the world’s most popular current and next-generation passenger and freighter aircraft.  Telair operates from facilities in Germany, Sweden and Singapore.  Nordisk designs and manufactures heavy duty pallets and lightweight cargo containers for commercial airlines from facilities in Norway and China.  The purchase price of the acquisition was approximately $293,000.  The businesses operate as part of our Structures and Systems segment.

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 February 29, 2012.  Any change in the fair value of the earn-out subsequent to the date of acquisition will be recognized in earnings.

We are continuing our review of our fair value estimate of assets acquired and liabilities assumed during the measurement period, which will conclude as soon as we receive the information we are seeking about facts and circumstances that existed as of the acquisition date, or learn that more information is not available.  This measurement period will not exceed one year from the acquisition date.  At the effective date of the acquisition, the assets acquired and liabilities assumed are generally required to be measured at fair value.

Our fair value estimate of assets acquired and liabilities assumed is pending completion of several elements, including the finalization of an independent appraisal and valuations of fair value of the assets acquired and liabilities assumed and final review by our management.  The primary areas that are not yet finalized relate to the fair value of accounts receivable, accounts payable, inventories, property and equipment, intangible assets, favorable or unfavorable contracts, operating leases or commitments, contingent liabilities and income and non-income related taxes.  Accordingly, there could be material adjustments to our consolidated financial statements, including changes in our depreciation and amortization expense related to the valuation of property and equipment and intangible assets acquired and their respective useful lives among other adjustments.

The final determination of the assets acquired and liabilities assumed will be based on the established fair value of the assets acquired and the liabilities assumed as of the acquisition date.  The excess of the purchase price over the fair value of net assets acquired is allocated to goodwill.  The final determination of the purchase price, fair values and resulting goodwill may differ significantly from what is reflected in these condensed consolidated financial statements.

The preliminary purchase price allocation for Telair, Nordisk and Airinmar follows:

Cash	$	5,200
Accounts receivable	55,100
Inventories	52,900
Prepaid expenses	4,700
Property, plant and equipment	14,500
Goodwill and identified intangibles	267,700
Notes payable	(1,600		)
Accounts payable	(21,400		)
