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, 2016 has been derived from audited financial statements.  To prepare the financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”), 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 GAAP, 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 28, 2017, the Condensed Consolidated Statements of Income and the Condensed Consolidated Statements of Comprehensive Income for the three and nine month periods ended February 28, 2017 and February 29, 2016, the Condensed Consolidated Statements of Cash Flows for the nine-month periods ended February 28, 2017 and February 29, 2016, and the Condensed Consolidated Statement of Changes in Equity for the nine month period ended February 28, 2017.  The results of operations for such interim periods are not necessarily indicative of the results for the full year.

New Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which provides guidance for revenue recognition.  This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets.  This ASU will supersede the revenue recognition requirements in ASC 605, Revenue Recognition, and most industry-specific guidance.  This ASU will also supersede certain cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts.  In August 2015, the FASB issued ASU No. 2015-14 which deferred the effective date of the new standard by one year which will make the new standard effective for us beginning June 1, 2018.  The ASU may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application.  We continue to gain an understanding of the standard’s revenue recognition model and are in the process of analyzing and documenting our significant customer contracts to evaluate the potential impact of the adoption of this new standard on our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases.  This ASU amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets, including those classified as operating leases under the current accounting guidance.  In addition, this ASU will require new qualitative and quantitative disclosures about the Company’s leasing activities.  This new standard will be effective for us beginning June 1, 2019 with early adoption permitted.  This ASU requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief.  We are currently evaluating the impact of the adoption of this new standard on our consolidated financial statements.

Note 2 — Discontinued Operations

On March 26, 2015, we completed the sale of our Telair Cargo Group to TransDigm, Inc.  The Telair Cargo Group was comprised of Telair International, Telair US, and Nordisk Aviation Products.  Cash received at closing in the fourth quarter of fiscal 2015 before fees and expenses was $705 million.  The sale also allowed for contingent consideration of up to $35 million based on the occurrence of certain post-closing events related to the A400M cargo system.  We recognized a pre-tax gain on the sale (net of transaction expenses and fees) of $198.6 million in the fourth quarter of fiscal 2015.

In the first quarter of fiscal 2016, we recognized a gain of $27.7 million net of expenses representing the resolution of the contingent consideration related to the A400M cargo system.

During fiscal 2015, we also announced our intention to sell our Precision Systems Manufacturing (“PSM”) businesses comprised of our metal and composite machined and fabricated parts manufacturing operations.  We recognized impairment charges of $57.5 million during fiscal 2015 to reduce the carrying value of the PSM business’s net assets to their expected value at the time of sale.

During the first quarter of fiscal 2017, we decided to retain our composite manufacturing operations within our Expeditionary Services segment as a product line within our mobility products business.  As a result, we reclassified our composite manufacturing operations into continuing operations for all periods presented.  Also during the first quarter of fiscal 2017, we decided to shut down the metal machining operation which had been available for sale.  The shutdown of the metal machining operation was completed prior to the end of the first quarter.

Telair Cargo Group and PSM’s metal machining operation are reported as discontinued operations in the Condensed Consolidated Statements of Income for all periods presented.  No amounts for general corporate overhead or interest expense were allocated to discontinued operations during the periods presented.

Assets of discontinued operations of $0.1 million and $4.0 million at February 28, 2017 and May 31, 2016, respectively, were classified as Deposits, prepaids, and other on the Condensed Consolidated Balance Sheet.  Liabilities of discontinued operations of $7.7 million and $12.5 million at February 28, 2017 and May 31, 2016, respectively, were classified as Accrued Liabilities on the Condensed Consolidated Balance Sheet.  Operating income from discontinued operations for the three and nine month periods ended February 28, 2017 and February 29, 2016 was comprised of the following:

Unless otherwise noted, amounts and disclosures throughout these Notes to Condensed Consolidated Financial Statements relate to our continuing operations.

Note 3 — 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 large airframe maintenance contracts and performance-based logistics programs are recognized by the percentage of completion method, based on the relationship of costs incurred to date to the estimated total costs.  When our experience and projections indicate adjustments to the estimated margin are required, changes are recognized using the cumulative catch-up method with the impact of the change from inception to date recorded in the current period.  We recognized favorable cumulative catch-up adjustments of $2.9 million and $2.5 million during the three month periods ended February 28, 2017 and February 29, 2016, respectively, and $6.7 million and $6.0 million during the nine month periods ended February 28, 2017 and February 29, 2016, respectively.

Lease revenues are recognized as earned.  Income from monthly or quarterly rental payments is recorded in the pertinent period according to the lease agreement.  However, for leases that provide variable rents, we recognize lease income on a straight-line basis.  In addition to a monthly lease rate, some engine leases require an additional rental amount based on the number of hours the engine is used in a particular month.  Lease income associated with these contingent rentals is recorded in the period in which actual usage is reported to us by the lessee, which is normally the month following the actual usage.

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

In June 2016, the U.S. Air Force awarded the new contract for the KC-10 Extender Contractor Logistics Support Program (“KC-10 Program”) to a competitor.  Our principal services under the prior contract for the KC-10 Program were completed in January 2017; however, we expect limited services will continue for an unspecified period of time.  Fiscal 2016 revenue and gross profit for the KC-10 Program was $148.1 million and $16.0 million, respectively, while average annual revenue and gross profit recognized over the last three fiscal years was $115.9 million and $7.4 million, respectively.

Included in accounts receivable as of February 28, 2017 and May 31, 2016, are $16.9 million and $29.8 million, respectively, of unbilled accounts receivable related to the KC-10 Program.  These unbilled accounts receivable relate to costs we have incurred on parts that were requested and accepted by our customer to support the KC-10 Program.  These costs have not been billed by us because the customer has not issued the final paperwork necessary to allow for billing.

Note 4 — Accounting for Stock-Based Compensation

Restricted Stock

In the three month period ended August 31, 2016, as part of our annual long-term stock incentive compensation, we granted 212,583 shares of performance-based restricted stock and 34,100 shares of time-based restricted stock to eligible employees.  The average grant date fair value per share for these shares was $24.00.  In June 2016, we also granted 50,000 shares of time-based restricted stock to members of the Board of Directors with a grant date fair value per share of $24.39.

Expense charged to operations for restricted stock was $1.6 million and $1.4 million during the three month periods ended February 28, 2017 and February 29, 2016, respectively, and $4.2 million and $3.6 million during the nine month periods ended February 28, 2017 and February 29, 2016, respectively.

Stock Options

The total intrinsic value of stock options exercised during the nine month periods ended February 28, 2017 and February 29, 2016 was $3.3 million and $0.9 million, respectively.   Expense charged to operations for stock options was $1.1 million and $0.9 million during the three month periods ended February 28, 2017 and February 29, 2016, respectively, and $3.4 million and $2.6 million during the nine month periods ended February 28, 2017 and February 29, 2016, respectively.

Note 5 — Inventory

The summary of inventories is as follows:

We had eight aircraft held for sale comprised of five fixed-wing and three rotary-wing aircraft at February 28, 2017 and May 31, 2016.

Note 6 — Aircraft Sale-Leaseback Transactions

During the nine-month period ended February 29, 2016, we received proceeds of $38.5 million from sale-leaseback transactions for two AW-189 rotary-wing aircraft.  The $1.7 million gain realized on the sale was deferred and is being amortized over the lease term of ten years.

Note 7 — Income Taxes

During the third quarter of 2017, we recorded a $0.7 million income tax benefit in discontinued operations related to tax provision to federal income tax return filing differences.

During the third quarter of fiscal 2016, we completed a reconciliation of our tax basis assets and liabilities and an analysis of our income tax payable which identified prior year immaterial errors netting to $0.2 million.  The correction of these errors was recognized in the three months ended February 29, 2016, with $1.7 million recognized as income tax expense in discontinued operations and $1.5 million recognized as income tax benefit within income from continuing operations.  We concluded these errors were not material to any prior reporting periods.

During the third quarter of fiscal 2016, we also recognized $2.8 million of income tax expense in discontinued operations related to changes in estimates associated with tax provision to federal income tax return filing differences.

Note 9 — Financing Arrangements

A summary of the carrying amount of our debt is as follows:

We maintain a Revolving Credit Facility with various financial institutions, as lenders and Bank of America, N.A., as administrative agent for the lenders which provides the Company an aggregate revolving credit commitment amount of $500 million.   The Company, under certain circumstances, may request an increase to the revolving credit commitment by an aggregate amount of up to $250 million, not to exceed $750 million in total.

On November 1, 2016, we entered into an amendment to our Revolving Credit Facility which extended the maturity of the Revolving Credit Facility to November 1, 2021, eliminated the condition of no material adverse charge for credit extensions and modified certain other provisions.

We are subject to a number of covenants under our financing arrangements, including restrictions that relate to the payment of cash dividends, maintenance of minimum net working capital and tangible net worth levels, sales of assets, additional financing, purchase of our shares and other matters.  We are in compliance with all financial and other covenants under our financing arrangements as of February 28, 2017.

At February 28, 2017 and May 31, 2016, our debt had a fair value that approximates the carrying value.  These debt instruments are classified as Level 3 in the fair value hierarchy which is defined as a fair value determined based upon one or more significant unobservable inputs.

Convertible Notes

During the three-month period ended August 31, 2015, we repurchased $14.4 million of our outstanding 2.25% convertible notes due March 1, 2016 for $14.6 million cash including $0.2 million of accrued interest and recognized a $0.3 million loss on the early extinguishment of the notes.  During the three-month period ended November 30, 2015, we repurchased $9.7 million of our outstanding 2.25% convertible notes due March 1, 2016 for $9.7 million cash and recognized a $0.1 million loss on the early extinguishment of the notes. On March 1, 2016, we retired the remaining balance of our 2.25% convertible notes at maturity for $26.0 million cash, including accrued interest of $0.3 million.

Note 10 — 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 and shares issuable upon vesting of restricted stock awards.

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

A reconciliation of the computations of basic and diluted earnings per share information for the three and nine month periods ended February 28, 2017 and February 29, 2016 is as follows:

At February 29, 2016 stock options to purchase 178,490 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 period then ended.  The average market price of our common shares during the interim period ended February 28, 2017 was greater than the exercise prices of our outstanding stock options.

During the first quarter of fiscal 2017, we sold certain assets related to our temperature-controlled container product line to Sonoco Protective Solutions, Inc. (“Sonoco”) for $5 million.  The sale price included $3 million paid at closing and $2 million in non-contingent, deferred consideration due over the next two years.  We recognized a gain of $2.6 million on the sale.  In conjunction with the sale, we also entered into a long-term manufacturing agreement to supply temperature-controlled containers to Sonoco over the next three years.

Note 13 — Business Segment Information

Consistent with how our chief operating decision making officer (Chief Executive Officer) evaluates performance and the way we are organized internally, we report our activities in two business segments:  Aviation Services comprised of supply chain and maintenance, repair and overhaul (“MRO”) activities and Expeditionary Services comprised of airlift and mobility activities.

The Aviation Services segment consists of businesses that provide spares and maintenance support for aircraft operated by our commercial and government/defense customers.  Sales in the Aviation Services segment are derived from the sale and lease of a wide variety of new, overhauled and repaired engine and airframe parts and components to the commercial aviation and government and defense markets.  We provide customized inventory supply chain management, performance based logistics programs, aircraft component repair management services, and aircraft modifications.  The segment also includes repair, maintenance and overhaul of aircraft, landing gear and components.  We also sell and lease used commercial aircraft through joint venture arrangements.  Cost of sales consists principally of the cost of product, direct labor, and overhead.

The Expeditionary Services segment consists of businesses that provide products and services supporting the movement of equipment and personnel by the U.S. Department of Defense (“DoD”), foreign governments and non-governmental organizations.  Sales in the Expeditionary Services segment are derived from the delivery of airlift services to mostly government and defense customers and the design and manufacture of pallets, shelters, and containers used to support the U.S. military’s requirements for a mobile and agile force.  We also provide system integration services for specialized command and control systems and composite manufacturing.  Cost of sales consists principally of aircraft maintenance costs, depreciation, the cost of material to manufacture products, direct labor and overhead.

The accounting policies for the segments are the same as those described in Note 1 of Notes to Consolidated Financial Statements included in our annual report on Form 10-K for the year ended May 31, 2016.  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.  Gross profit is calculated by subtracting cost of sales from sales.  The assets and certain expenses related to corporate activities are not allocated to the segments.  Our reportable segments are aligned principally around differences in products and services.

Selected financial information for each segment is as follows:
