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, 2018 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 November 30, 2018, the Condensed Consolidated Statements of Operations and Condensed Consolidated Statements of Comprehensive Income (Loss) for the three- and six-month periods ended November 30, 2018 and 2017, the Condensed Consolidated Statements of Cash Flows for the six-month periods ended November 30, 2018 and 2017, and the Condensed Consolidated Statement of Changes in Equity for the six-month period ended November 30, 2018.  The results of operations for such interim periods are not necessarily indicative of the results for the full year.

New Accounting Pronouncements Adopted

In March 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-07, Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.  This ASU requires an employer to report the service cost component of net periodic pension benefit cost in the same line item as other compensation costs for those related employees.  Other components of net pension cost, including interest, expected return on plan assets, and actuarial gains and losses are to be presented outside of operating income.  We adopted this ASU on June 1, 2018, which resulted in $0.3 million and $0.6 million of pension income included in Other income (expense), net in the Condensed Consolidated Statement of Operations for the three- and six-month periods ended November 30, 2018, respectively.  The Condensed Consolidated Statement of Operations for the three- and six month periods ended November 30, 2017 were not restated as the non-service cost components of pension expense were not material to fiscal 2018.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASC 606”), which provides guidance for revenue recognition.  ASC 606 superseded the revenue recognition requirements in Accounting Standards Codification (“ASC”) 605, Revenue Recognition, and most industry-specific guidance.

We adopted ASC 606 on June 1, 2018 using the modified retrospective method.  Under that approach, prior periods have not been restated and continue to be reported under the accounting standards in effect for those periods.  A discussion of our revised accounting policy for revenue recognition is included in Note 3.

(Dollars in millions, except per share amounts)

We elected to use the practical expedient allowing for the application of ASC 606 only to contracts that were not completed as of June 1, 2018.  We recognized the cumulative effect of initially applying ASC 606 as a decrease of $20.4 million to the opening balance of retained earnings as of June 1, 2018.  The impact of the adoption of ASC 606 on our Condensed Consolidated Balance Sheet was as follows:

	As of May 31, 2018		ASC 606 Adjustments			As of June 1, 2018
Accounts receivable, net	$	202.0	$	(31.4	)	$	170.6
Inventories	460.7		(17.3		)	443.4
Contract assets—current	—		49.6			49.6
Other current assets	26.2		(0.9		)	25.3
Other non-current assets	118.9		(19.0		)	99.9
Accrued liabilities	138.3		9.1			147.4
Deferred tax liabilities	15.7		(6.6		)	9.1
Other liabilities and deferred income	62.2		(1.1		)	61.1
Retained earnings	733.2		(20.4		)	712.8

The adoption of ASC 606 impacted us in three primary areas.  First, we have certain contracts in which revenue is recognized using the percentage of completion method over the expected term of the contract.  Under ASC 606, the contract term used for revenue recognition purposes was shortened to exclude any unexercised customer option years or incorporate customer rights to terminate the contract without significant penalty as we do not have any enforceable rights or obligations prior to the exercise of the underlying option.  The impact of this change as of June 1, 2018 resulted in the elimination of certain deferred costs and the establishment of accrued liabilities reflecting our estimated obligations under the contracts.  For this change, we recognized a decrease of $22.1 million to the opening balance of retained earnings as of June 1, 2018.

Second, we have contracts under which we perform repair services on customer-owned assets whereby the customer simultaneously receives the benefits of the repair.  These contracts also transitioned to an over time revenue recognition model as of June 1, 2018 compared to our prior policy of recognizing revenue at the time of shipment.  The impact of this change as of June 1, 2018 resulted in the elimination of certain inventory and accounts receivable amounts and the establishment of a contract asset reflecting the over time revenue recognition treatment.  For this change, we recognized an increase of $1.3 million to the opening balance of retained earnings as of June 1, 2018.

Third, we have certain contracts under which we manufacture products with no alternative use as the customer owns the underlying intellectual property and we have an enforceable right to payment from the customer.  As a result, we now recognize revenue for these contracts over time as opposed to at the time of shipment, which was our policy prior to June 1, 2018.  The impact of this change as of June 1, 2018 resulted in the elimination of certain inventory amounts and the establishment of a contract asset reflecting the over time revenue recognition treatment.  For this change, we recognized an increase of $0.4 million to the opening balance of retained earnings as of June 1, 2018.

The impact of the ASC 606 adoption on our Condensed Consolidated Balance Sheet as of November 30, 2018 and our Condensed Consolidated Statement of Operations for the three- and six-month periods ended November 30, 2018 was as follows:

	As Reported		ASC 606 Adjustments			Balances Excluding ASC 606

Gross profit	78.3		1.1			79.4
Provision for income taxes	3.0		0.3			3.3
Income from continuing operations	11.2		0.8			12.0

	Six Months Ended November 30, 2018

Provision for income taxes	5.3		(0.5		)	4.8
Income from continuing operations	30.1		(1.6		)	28.5

Excluding the ASC 606 adjustments from our reported results for the six-month period ended November 30, 2018, our Condensed Consolidated Statement of Cash Flows would include the changes of asset and liability accounts described above, with no impact on our net cash used in operating activities.

New Accounting Pronouncements Not Yet Adopted

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 and is required to be adopted using a modified retrospective approach.   The new standard provides us an option to recognize the cumulative effect adjustment on retained earnings as of June 1, 2019 or as of the beginning of the earliest period presented.  We are in the preliminary phases of our assessment of this ASU and continue to gather information on our lease population and portfolio.  We are also considering the terms and conditions of our other arrangements that could meet the definition of a lease and designing and implementing new processes and controls, including information technology tools.  While this assessment continues, we have not yet selected a transition date nor have we determined the effect of this ASU on our consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.  This ASU permits the reclassification of tax effects stranded in accumulated other comprehensive income to retained earnings as a result of the Tax Reform Act.  This new standard will be effective for us beginning June 1, 2019 with early adoption permitted.  We are currently evaluating the impact of this new standard on our consolidated financial statements.

Note 2 — Discontinued Operations

During the third quarter of fiscal 2018, we decided to pursue the sale of our Contractor-Owned, Contractor-Operated (“COCO”) business previously included in our Expeditionary Services segment.  Due to this strategic shift, the assets, liabilities, and results of operations of our COCO business have been reported as discontinued operations for all periods presented.  Goodwill was allocated to this business based on its relative fair value to the reporting unit.  The fair value of the reporting unit was determined based on a combination of the expected net proceeds upon sale and a discounted cash flow analysis.  As the fair value of the COCO business was below its carrying value, a goodwill impairment charge of $9.8 million, representing the estimated loss on disposal, was recorded in the third quarter of fiscal 2018.

Our COCO business completed certain contracts in the second quarter of fiscal 2018.  As the aircraft supporting these contracts were not placed on new contracts combined with the continued decline in operational tempo within the U.S. Department of Defense and an excess supply of aircraft assets in the market, we determined there was an impairment triggering event and tested the recoverability of our COCO assets.  As a result, we recognized impairment and other charges of $54.2 million in the second quarter of fiscal 2018. The fair value of the aircraft and related assets was based on available market data for similar assets.

The COCO business is available for immediate sale and we continue to actively market the COCO business at a reasonable price in relation to its fair value.  We expect a sale of the COCO business to be completed before the end of fiscal 2019.

No amounts for general corporate overhead or interest expense were allocated to discontinued operations during the periods presented.  Unless otherwise noted, amounts and disclosures throughout these Notes to Consolidated Financial Statements relate to our continuing operations.

Note 3 — Revenue Recognition

Revenue is measured based on a consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer.

Our unit of accounting for revenue recognition is a performance obligation included in our customer contracts.  A performance obligation reflects the distinct good or service that we must transfer to a customer.  At contract inception, we evaluate if the contract should be accounted for as a single performance obligation or if the contract contains multiple performance obligations.  In some cases, our contract with the customer is considered one performance obligation as it includes factors such as whether the good or service being provided is significantly integrated with other promises in the contract, whether the service provided significantly modifies or customizes another good or service or whether the good or service is highly interdependent or interrelated.  If the contract has more than one performance obligation, the Company determines the standalone price of each distinct good or service underlying each performance obligation and allocates the transaction price based on their relative standalone selling prices.

The transaction price of a contract, which can include both fixed and variable amounts, is allocated to each performance obligation identified.  Some contracts contain variable consideration, which could include incremental fees or penalty provisions related to performance.  Variable consideration that can be reasonably estimated based on current assumptions and historical information is included in the transaction price at the inception of the contract but limited to the amount that is probable that a significant reversal in the amount of cumulative revenue recognized will not occur.  Variable consideration that cannot be reasonably estimated is recorded when known.

Our performance obligations are satisfied over time as work progresses or at a point in time based on transfer of control of products and services to our customers.  The majority of our sales from products are recognized at a point in time upon transfer of control to the customer, which generally occurs upon shipment.  In connection with certain sales of products, we also provide logistics services, which include inventory management, replenishment, and other related services.  The price of such services is generally included in the price of the products delivered to the customer, and revenues are recognized upon delivery of the product, at which point, the customer has obtained control of the product.  We do not account for these services separate from the related product sales as the services are inputs required to fulfill part orders received from customers.

For our performance obligations that are satisfied over time, we measure progress in a manner that depicts the performance of transferring control to the customer. As such, we utilize the input method of cost-to-cost to recognize revenue over time as this depicts when control of the promised goods or services are transferred to the customer.  Revenue is recognized based on the relationship of actual costs incurred to date to the estimated total cost at completion of the performance obligation.  We are required to make certain judgments and estimates, including estimated revenues and costs, as well as inflation and the overall profitability of the arrangement.  Key assumptions involved include future labor costs and efficiencies, overhead costs, and ultimate timing of product delivery.  Differences may occur between the judgments and estimates made by management and actual program results.

Changes in estimates and assumptions related to our arrangements accounted for using the cost-to-cost method are recorded using the cumulative catch-up method of accounting.  These changes are primarily adjustments to the estimated profitability for our long-term, power-by-the-hour programs where we provide component inventory management and repair services.

For the three-month period ended November 30, 2018, we recognized favorable cumulative catch-up adjustments of $3.1 million.  For the three-month period ended November 30, 2017, we recognized favorable and unfavorable adjustments of $1.0 million and $0.6 million, respectively.  When considering these adjustments on a net basis, we recognized net favorable adjustments of $3.1 million and $0.4 million in the three-month periods ended November 30, 2018 and 2017, respectively.

For the six-month period ended November 30, 2018, we recognized favorable and unfavorable cumulative catch-up adjustments of $3.8 million and $0.5 million, respectively.  For the six-month period ended November 30, 2017, we recognized favorable and unfavorable adjustments of $1.0 million and $0.6 million, respectively.  When considering these adjustments on a net basis, we recognized net favorable adjustments of $3.3 million and $0.4 million in the six-month periods ended November 30, 2018 and 2017, respectively.

Under most of our U.S. government contracts, if the contract is terminated for convenience, we are entitled to payment for items delivered and fair compensation for work performed, the costs of settling and paying other claims, and a reasonable profit on the costs incurred or committed.

We have elected to use certain practical expedients permitted under ASC 606.  Shipping and handling fees and costs incurred associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of sales in our Condensed Consolidated Statement of Operations, and are not considered a performance obligation to our customers.  Our reported sales on our Condensed Consolidated Statement of Operations are net of any sales or related non-income taxes.  We also utilize the “as invoiced” practical expedient in certain cases where performance obligations are satisfied over time and the invoiced amount corresponds directly with the value we are providing to the customer.

Contract Assets and Liabilities

The timing of revenue recognition, customer billings, and cash collections results in a contract asset or contract liability at the end of each reporting period.  Contract assets consist of unbilled receivables or costs incurred where revenue recognized over time using the cost-to-cost model exceeds the amounts billed to customers.  Contract liabilities include advance payments and billings in excess of revenue recognized. Certain customers make advance payments prior to the satisfaction of our performance obligations on the contract.  These amounts are recorded as contract liabilities until such performance obligations are satisfied, either over time as costs are incurred or at a point in time when deliveries are made.  Contract assets and contract liabilities are determined on a contract-by-contract basis.

Net contract assets and liabilities are as follows:

	November 30, 2018			June 1, 2018			Change
Contract assets — current	$	63.0		$	49.6		$	13.4
Contract assets — non-current	21.3			12.9			8.4
Contract liabilities — current	(9.3		)	(9.4		)	0.1
Contract liabilities — non-current	(68.3		)	(33.0		)	(35.3		)
Net contract assets	$	6.7		$	20.1		$	(13.4	)

Contract assets — non-current is reported within Other non-current assets, Contract liabilities — current is reported within Accrued Liabilities, and Contract liabilities — non-current is reported within Other liabilities and deferred income on our Condensed Consolidated Balance Sheet.  Changes in contract assets and contract liabilities primarily result from the timing difference between our performance of services and payments from customers.  For the three- and six-month periods ended November 30, 2018, we recognized revenue of $76.4 million and $156.5 million that was previously included in the beginning balance of contract liabilities.

In the three-month period ended November 30, 2018, we recognized a provision for doubtful accounts of $12.4 million related to the bankruptcy of a European airline customer.  The provision included impairment of non-current contract assets of $7.6 million, allowance for doubtful accounts of $3.3 million, and other liabilities of $1.5 million.

Remaining Performance Obligations

As of November 30, 2018, we had approximately $1.3 billion of remaining performance obligations, also referred to as firm backlog, which excludes unexercised contract options and potential orders under our indefinite-delivery, indefinite-quantity (IDIQ) contracts.  We expect that approximately 40% of this backlog will be recognized as revenue over the next 12 months with the majority of the remainder recognized over the next three years.  The amount of remaining performance obligations that is expected to be recognized as revenue beyond 12 months primarily relates to our long-term, power-by-the-hour programs where we provide component inventory management and repair services.

Note 7 — Sale of Receivables

On February 23, 2018, we entered into a Purchase Agreement with Citibank N.A. (“Purchaser”) for the sale, from time to time, of certain accounts receivable due from certain customers (the “Purchase Agreement”).  Under the Purchase Agreement, the maximum amount of receivables sold is limited to $150 million.  The term of the Purchase Agreement runs through February 22, 2019; however, the Purchase Agreement may also be terminated earlier under certain circumstances.  The term of the Purchase Agreement shall be automatically extended for annual terms unless either party provides advance notice that they do not intend to extend the term.

We have no retained interests in the sold receivables, other than limited recourse obligations in certain circumstances, and only perform collection and administrative functions for the Purchaser.  We account for these receivable transfers as sales under ASC 860, Transfers and Servicing, and de-recognize the sold receivables from our Consolidated Balance Sheet.

During the six-month period ended November 30, 2018, we sold $351.0 million of receivables under the Purchase Agreement and remitted $327.5 million to the Purchaser on their behalf.  During fiscal 2018, we sold $239.6 million of receivables under the Purchase Agreement and remitted $167.9 million to the Purchaser on their behalf.  As of November 30, 2018 and May 31, 2018, we had collected cash of $15.0 million and $10.5 million, respectively, which was not yet remitted to the Purchaser and was classified as Restricted cash on our Condensed Consolidated Balance Sheet.  During the three- and six-month periods ended November 30, 2018, we incurred discounts on the sale of our receivables of $0.6 million and $1.0 million, respectively, which were recognized as an expense in Other income, net on our Condensed Consolidated Statements of Operations.

Note 8 — Financing Arrangements

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

	November 30,			May 31,
	2018			2018
Revolving Credit Facility expiring November 1, 2021 with interest payable monthly	$	197.0		$	130.0
Term loan due November 1, 2021 with interest payable monthly	23.3			23.9
Industrial revenue bond due August 1, 2018	—			25.0
Total debt	220.3			178.9
Debt issuance costs, net	(1.4		)	(1.7		)
Long-term debt	$	218.9		$	177.2

At November 30, 2018, our variable rate debt had a fair value that approximates its carrying value and is classified as Level 2 in the fair value hierarchy.

The industrial revenue bond was paid on August 1, 2018 using our Revolving Credit Facility.

On October 18, 2017, we entered into a Credit Agreement with the Canadian Imperial Bank of Commerce, as lender (the “Credit Agreement”).  The Credit Agreement provided a Canadian $31 million term loan with the proceeds used to fund the acquisition of two maintenance, repair, and overhaul (“MRO”) facilities in Canada from Premier Aviation.  The term loan is due in full at the expiration of the Credit Agreement on November 1, 2021 unless terminated earlier pursuant to the terms of the Credit Agreement.  Interest is payable monthly on the term loan at the offered fluctuating Canadian Dollar Offer Rate plus 125 to 225 basis points based on certain financial measurements if a Bankers’ Acceptances loan, or at the offered fluctuating Prime Rate plus 25 to 125 basis points based on certain financial measurements, if a Prime Rate loan.

Our financing arrangements also require us to comply with leverage and interest coverage ratios, maintain a minimum net working capital level, and comply with certain affirmative and negative covenants, including those relating to financial reporting and notification, payment of indebtedness, cash dividends, taxes and other obligations, compliance with applicable laws, and limitations on additional liens, indebtedness, acquisitions, investments and disposition of assets.  The Revolving Credit Facility also requires our significant domestic subsidiaries, and any subsidiaries that guarantee our other indebtedness, to provide a guarantee of payment under the Revolving Credit Facility.  At November 30, 2018, we were in compliance with the financial and other covenants in our financing agreements.

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 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.

Earnings (Loss) per share — basic and diluted	$	0.20		$	(0.66	)	$	0.62		$	(0.35	)

The potential dilutive effect of 290,000 shares relating to stock options was excluded from the computation of weighted average common shares outstanding — diluted for both the three- and six-month periods ended November 30, 2018 as the shares would have been anti-dilutive.  At November 30, 2017, the average market price of our common shares was in excess of the exercise prices of all of our outstanding options.

Note 12 — 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 operating segments:  Aviation Services comprised of supply chain and MRO activities and Expeditionary Services comprised of manufacturing activities.

In the first quarter of fiscal 2019, we re-aligned the composition of our operating segments to leverage the full breadth of our operational expertise in Aviation Services.  Our government-owned, contractor-operated business, which includes the INL/A WASS program, was previously included in our Expeditionary Services segment and is now reported within our Aviation Services segment for all periods presented.

The Aviation Services segment consists of aftermarket support and services offerings that provide spare parts 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, customer fleet management and operations, and aircraft component repair management services.  The segment also includes repair, maintenance and overhaul of aircraft, landing gear and components.  Cost of sales consists principally of the cost of product, direct labor, and overhead.

The Expeditionary Services segment consists of primarily manufacturing operations with sales derived from the design and manufacture of pallets, shelters, and containers used to support the U.S. military’s requirements for a mobile and agile force including engineering, design, and system integration services for specialized command and control systems.  This segment also designs and manufactures advanced composite materials for commercial, business and military aircraft.  Cost of sales consists principally of the cost of material to manufacture products, direct labor and overhead.

The accounting policies for the segments are the same as those described in Note 1 of Notes to Consolidated Financial Statements included in our annual report on Form 10-K for the year ended May 31, 2018 except for our revised accounting policy for revenue recognition.  We adopted ASC 606 on June 1, 2018 and our revised accounting policy is further described in Note 3.

Our chief operating decision making officer (Chief Executive Officer) evaluates performance based on the operating 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.

(“Airlift”) under the federal civil False Claims Act (“FCA”).  The investigation relates to Airlift’s performance of several contracts awarded by the U.S. Transportation Command concerning the operations and maintenance of rotary-wing and fixed-wing aircraft in Afghanistan and Africa, as well as several U.S. Navy contracts.  In June 2018, the DoJ informed Airlift that part of the investigation was precipitated by a lawsuit filed under the qui tam provisions of the FCA by a former employee of Airlift.  That lawsuit remains under seal.   Airlift is cooperating with the DoJ investigation.

Item 2 — Management’s Discussion and Analysis of Financial Condition and Results of Operations

  (Dollars in millions)

General Overview

We report our activities in two operating segments:  Aviation Services comprised of supply chain and maintenance, repair, and overhaul (“MRO”) activities and Expeditionary Services comprised of manufacturing activities.

In the first quarter of fiscal 2019, we re-aligned the composition of our operating segments to leverage the full breadth of our operational expertise in Aviation Services.  Our government-owned, contractor-operated business, which includes the INL/A WASS program and was previously included in our Expeditionary Services segment, is now reported within our Aviation Services segment for all periods presented.

The Aviation Services segment consists of aftermarket support and services offerings that provide spare parts 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, customer fleet management and operations, and aircraft component repair management services.  The segment also includes repair, maintenance and overhaul of aircraft, landing gear and components.  Cost of sales consists principally of the cost of product, direct labor, and overhead.

The Expeditionary Services segment consists of primarily manufacturing operations with sales derived from the design and manufacture of pallets, shelters, and containers used to support the U.S. military’s requirements for a mobile and agile force including engineering, design, and system integration services for specialized command and control systems.  This segment also designs and manufactures advanced composite materials for commercial, business and military aircraft.  Cost of sales consists principally of the cost of material to manufacture products, direct labor and overhead.

The accounting policies for the segments are the same as those described in Note 1 of Notes to Consolidated Financial Statements included in our annual report on Form 10-K for the year ended May 31, 2018 except for our revised accounting policy for revenue recognition.  We adopted ASC 606 on June 1, 2018 and our revised accounting policy is further described in Note 3.

Our chief operating decision making officer (Chief Executive Officer) evaluates performance based on the operating 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.

Beginning in fiscal 2015, we implemented a comprehensive strategic plan to narrow our strategy to focus on our best-in-class aviation and expeditionary services through our two business segments: Aviation Services and Expeditionary Services.  We sold our Telair Cargo Group for cash of $714 million, resulting in pre-tax gains of $198.6 million in the fourth quarter of fiscal 2015 (and $27.7 million in the first quarter of fiscal 2016 from the receipt of contingent consideration).  We used the proceeds from the sale in fiscal 2015 to reduce our total debt and return capital to stockholders through common stock repurchases and dividends.

Through execution of our strategic plan over the last three years, we have succeeded in expanding customer relationships and securing new flight hour component inventory management and repair programs with multiple international commercial customers and government customers.  We also invested in our rotable assets to support these programs and continued our focus on expanding our business development resources.  These investments in our supply chain activities have allowed us to increase market share, expand our customer base, and enlarge our geographic footprint.

23

In fiscal 2018, we began the ramp-up for the 15-year, U.S. Air Force Landing Gear Performance-Based Logistics One program.  Under this program, we are providing total supply chain management including purchasing, distribution and inventory control to support all landing gear components for the U.S. Air Force’s fleet of C-130, KC-135 and E-3 aircraft.

In fiscal 2018, we also began providing services to the U.S. Department of State (“DoS”) under the INL/A Worldwide Aviation Support Services (“INL/A WASS”) contract.  This contract leverages our capabilities in aviation services, including flight operations, supply chain logistics, and other services.  We are the prime contractor on this 10-year performance-based contract to globally operate and maintain the DoS fleet of fixed and rotary-wing aircraft.  We successfully completed the transition and phase-in of the WASS program in June 2018.  We have full operational capability at all contract sites, which include Afghanistan, Iraq, Panama, Peru, and Patrick Air Force Base as well as support locations in Brevard County, Florida.

Fiscal 2019

For fiscal 2019, we continue to see strength in our Aviation Services segment given its leadership positions in value-added services to both commercial and government and defense customers.  Long-term aftermarket growth trends are favorable and our comprehensive suite of integrated services will continue to drive growth across our diverse base of customers.

We remain in a strong financial position to further execute on our strategy in fiscal 2019.  Both our commercial and government businesses are executing on our many contract wins and are delivering growth in fiscal 2019.  Our cash on hand plus unused capacities on our Revolving Credit Facility and accounts receivable financing program was $380 million at November 30, 2018.  We expect to invest opportunistically in expanding our comprehensive suite of services to the global commercial aviation and government and defense markets.  We continue to have the flexibility in our balance sheet to invest in our growth.

Three Month Period Ended November 30, 2018

Aviation Services Segment

Sales in the Aviation Services segment increased $71.2 million or 18.2% over the prior year period due to a $49.1 million or 55.6% increase in sales to government and defense customers.  The increase in sales to government and defense customers was primarily attributable to the INL/A WASS program, which achieved full operational capability in June 2018.

During the second quarter of fiscal 2019, sales in this segment to commercial customers increased $22.1 million or 7.3% over the prior year period.  The increase was primarily due to increased demand in our supply chain activities.

Changes in estimates and assumptions related to our arrangements accounted for using the cost-to-cost method are recorded using the cumulative catch-up method of accounting.  For the second quarter of fiscal 2019, we recognized favorable cumulative catch-up adjustments of $3.1 million compared to favorable and unfavorable adjustments of $1.0 million and $0.6 million, respectively, in the prior year period.  When considering these adjustments on a net basis, we recognized favorable adjustments of $3.1 million and $0.4 million for the second quarter of fiscal 2019 and 2018, respectively.  These adjustments relate to our long-term, power-by-the-hour programs where we provide component inventory management and repair services.

Cost of sales in Aviation Services increased $62.3 million or 19.1% over the prior year period, which was largely in line with the sales increase discussed above.  Gross profit in the Aviation Services segment increased $8.9 million or 13.5% over the prior year period.  Gross profit on sales to government and defense customers increased $11.8 million or 71.1% over the prior year primarily driven by the start of the INL/A WASS program.  Gross profit margin on sales to government and defense customers increased to 20.7% from 18.8% primarily as a result of the mix of products and services sold.

Gross profit on sales to commercial customers decreased $2.9 million or 5.9% from the prior year period primarily due to the lower volume in our MRO activities.  The gross profit margin on sales to commercial customers decreased from 16.3% to 14.3% reflecting the impact of these lower volumes.

Expeditionary Services Segment

Sales in the Expeditionary Services segment increased $1.5 million or 5.2% over the prior year period primarily due to stronger demand for our mobility products.

Gross profit in the Expeditionary Services segment decreased $1.3 million or 27.7% from the prior period and gross profit margin decreased to 11.2% from 16.3% primarily as a result of the mix of products sold.

25

Provision for Doubtful Accounts

In the three-month period ended November 30, 2018, we recognized a provision for doubtful accounts of $12.4 million related to the bankruptcy of a European airline customer.  The provision included impairment of non-current contract assets of $7.6 million, allowance for doubtful accounts of $3.3 million, and other liabilities of $1.5 million.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $0.3 million over the prior year period.  As a percent of sales, selling, general and administrative expenses decreased to 10.0% from 11.6% in the prior year period reflecting improved leverage of our existing cost structure to support the sales growth.

Interest Expense

Interest expense increased $0.6 million over the prior year period primarily as a result of higher borrowings and higher interest rates on our Revolving Credit Facility.

Income Taxes

Our effective income tax rate for continuing operations was 21.1% in the second quarter of fiscal 2019 compared to 34.0% in the prior year period primarily due to the Tax Cuts and Jobs Act (the “Tax Reform Act”), which significantly reduced the corporate federal income tax rate to 21% from 35%.

Six Month Period Ended November 30, 2018

Aviation Services Segment

Sales in the Aviation Services segment increased $138.3 million or 18.1% over the prior year period due to a $106.3 million or 65.3% increase in sales to government and defense customers.  The increase in sales to government and defense customers was primarily attributable to the INL/A WASS program, which achieved full operational capability in June 2018.  Sales in this segment to commercial customers increased $32.0 million or 5.3% over the prior year period primarily due to increased demand in our supply chain activities.

Changes in estimates and assumptions related to our arrangements accounted for using the cost-to-cost method are recorded using the cumulative catch-up method of accounting.  For the six-month period ended November 30, 2018, we recognized favorable and unfavorable cumulative catch-up adjustments of $3.8 million and $0.5 million, respectively, compared to favorable and unfavorable adjustments of $1.0 million and $0.6 million, respectively, in the prior year period.  When considering these adjustments on a net basis, we recognized favorable cumulative catch-up adjustments of $3.3 million and $0.4 million for the six-month periods ended November 30, 2018 and 2017, respectively.  These adjustments relate to our long-term, power-by-the-hour programs where we provide component inventory management and repair services.

Cost of sales in Aviation Services increased $120.1 million or 18.8% over the prior year period, which was largely in line with the sales increase discussed above.  Gross profit in the Aviation Services segment increased $18.2 million or 14.7% over the prior year period.  Gross profit on sales to government and defense customers increased $22.5 million or 74.5% over the prior year primarily driven by the start of the INL/A WASS program.  Gross profit margin on sales to government and defense customers increased to 19.6% from 18.6% primarily as a result of the mix of products and services sold.

Gross profit on sales to commercial customers decreased $4.3 million or 4.6% from the prior year period primarily due to the lower volume in our MRO activities.  The gross profit margin on sales to commercial customers decreased from 15.6% to 14.1% reflecting the impact of these lower volumes.

26

Expeditionary Services Segment

Sales in the Expeditionary Services segment increased $2.8 million or 5.0% over the prior year period primarily due to stronger demand for our mobility products.

Gross profit in the Expeditionary Services segment decreased $1.0 million or 11.8% from the prior period and gross profit margin decreased to 12.9% from 15.3% primarily as a result of the mix of products sold.

Provision for Doubtful Accounts

In the six-month period ended November 30, 2018, we recognized a provision for doubtful accounts of $12.4 million related to the bankruptcy of a European airline customer.  The provision included impairment of non-current contract assets of $7.6 million, allowance for doubtful accounts of $3.3 million, and other liabilities of $1.5 million.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $4.2 million over the prior year period.  As a percent of sales, selling, general and administrative expenses decreased to 10.1% from 11.4% in the prior year period reflecting improved leverage of our existing cost structure to support the sales growth.

Interest Expense

Interest expense increased $1.0 million in fiscal 2019 over the prior year period primarily as a result of higher borrowings and higher interest rates on our Revolving Credit Facility.

Income Taxes

Our effective income tax rate for continuing operations was 15.0% for the six-month period ended November 30, 2018 compared to 31.6% in the prior year period.  The effective tax rate was impacted by the Tax Cuts and Jobs Act (the “Tax Reform Act”), which significantly reduced the corporate federal income tax rate to 21% from 35%.  Higher excess tax benefits from the vesting of restricted shares and stock options exercises in fiscal 2019 compared to the prior year period also contributed to the lower effective tax rate in fiscal 2019.  We recognized $2.7 million of excess tax benefits as a reduction to income tax expense during fiscal 2019 compared to $1.6 million in the prior year period.

Liquidity, Capital Resources and Financial Position

Our operating activities are funded and commitments met through the generation of cash from operations.  In addition to operations, our current capital resources include an unsecured Revolving Credit Facility and an accounts receivable financing program.  Periodically, we may also raise capital through common stock and debt financings in the public or private markets.  We continually evaluate various financing arrangements, including the issuance of common stock or debt, which would allow us to improve our liquidity position and finance future growth on commercially reasonable terms. Our continuing ability to borrow from our lenders and issue debt and equity securities to the public and private markets in the future may be negatively affected by a number of factors, including the overall health of the credit markets, general economic conditions, airline industry conditions, geo-political events, and our operating performance.  Our ability to generate cash from operations is influenced primarily by our operating performance and changes in working capital.

At November 30, 2018, our liquidity and capital resources included cash of $25.7 million and working capital of $696.5 million.

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 and matures November 1, 2021.  The Company, under certain circumstances, has the ability to request an increase to the revolving credit commitment by an aggregate amount of up to $250 million, not to exceed $750 million in total.

27

Borrowings under the Revolving Credit Facility bear interest at the offered Eurodollar Rate plus 100 to 200 basis points based on certain financial measurements if a Eurodollar Rate loan, or at the offered fluctuating Base Rate plus 0 to 100 basis points based on certain financial measurements if a Base Rate loan.

Borrowings outstanding under the Revolving Credit Facility at November 30, 2018 were $197.0 million and there were approximately $15.2 million of outstanding letters of credit, which reduced the availability of this facility to $287.8 million. There are no other terms or covenants limiting the availability of this facility. We also had $9.6 million available under foreign lines of credit at November 30, 2018.

At November 30, 2018, we complied with all financial and other covenants under our financing arrangements.

Cash Flows from Operating Activities

Net cash used in operating activities—continuing operations was $41.2 million in the six-month period ended November 30, 2018 compared to cash used of $34.8 million in the prior year period.  The increase from the prior period of $6.4 million was primarily attributable to higher inventory investments in the current year and increased accounts receivable primarily attributable to the INL/A WASS program, which achieved full operational capability in June 2018.  These increases were partially offset by other working capital changes, including vendor invoice payment timing.

Cash Flows from Investing Activities

Net cash used in investing activities—continuing operations was $9.0 million during the six-month period ended November 30, 2018 compared to $28.5 million in the prior year period.  In fiscal 2018, we acquired the outstanding shares of two MRO facilities in Quebec and Ontario, Canada owned by Premier Aviation for approximately $24.8 million, which included $22.9 million paid at closing.

Cash Flows from Financing Activities

Net cash provided from financing activities—continuing operations was $44.9 million during the six-month period ended November 30, 2018 compared to $60.3 million in the prior year period.  The additional cash provided in the prior year was primarily attributable to proceeds from a new term loan of $24.8 million to finance the acquisition of the two Canadian MRO facilities previously discussed.

Critical Accounting Policies and Significant Estimates

We make a number of significant estimates, assumptions and judgments in the preparation of our financial statements.  See Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2018 Form 10-K for a discussion of our critical accounting policies.  There have been no significant changes to the application of our critical accounting policies during the first quarter of fiscal 2019 other than the adoption of ASC 606 on June 1, 2018, which supersedes the revenue recognition guidance in ASC 605.  Under ASC 606, revenue is recognized as goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services.  Our new accounting policies for revenue recognition are included in Notes 1 and 3 to the Condensed Consolidated Financial Statements.

28

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 set forth under Part I, Item 1A in our Annual Report on Form 10-K for the year ended May 31, 2018.  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.

29

Item 3 — Quantitative and Qualitative Disclosures About Market Risk

Our exposure to market risk includes fluctuating interest rates under our credit agreements, changes in foreign exchange rates, and credit losses on accounts receivable.  See Note 1 of Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended May 31, 2018 for a discussion of accounts receivable exposure.

Foreign Currency Risk.  Revenues and expenses of our foreign operations are translated at average exchange rates during the period, 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 the U.S. dollar against foreign currencies would not have had a material impact on our financial position or continuing operations for the quarter ended November 30, 2018.

Interest Rate Risk.  Refer to the section Quantitative and Qualitative Disclosures about Market Risk in our Annual Report on Form 10-K for the year ended May 31, 2018.  There were no significant changes during the quarter ended November 30, 2018.

Item 4 — Controls and Procedures

As required by Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of November 30, 2018.  This evaluation was carried out under the supervision and with participation of our Chief Executive Officer and our Chief Financial Officer.  There are inherent limitations to the effectiveness of any system of disclosure controls and procedures.  Therefore, effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.  Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective as of November 30, 2018, ensuring that information required to be disclosed in the reports that are filed under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported in a timely manner.

Effective June 1, 2018, we adopted the new revenue standard under ASC 606 using the modified retrospective method of adoption.  We have implemented certain changes to our internal controls over financial reporting to support the reporting and disclosure requirements of the new revenue standard.  There were no other changes in our internal control over financial reporting during the second quarter ended November 30, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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, 2018 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 November 30, 2018, the Condensed Consolidated Statements of Operations and Condensed Consolidated Statements of Comprehensive Income (Loss) for the three- and six-month periods ended November 30, 2018 and 2017, the Condensed Consolidated Statements of Cash Flows for the six-month periods ended November 30, 2018 and 2017, and the Condensed Consolidated Statement of Changes in Equity for the six-month period ended November 30, 2018.  The results of operations for such interim periods are not necessarily indicative of the results for the full year.

New Accounting Pronouncements Adopted

In March 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-07, Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.  This ASU requires an employer to report the service cost component of net periodic pension benefit cost in the same line item as other compensation costs for those related employees.  Other components of net pension cost, including interest, expected return on plan assets, and actuarial gains and losses are to be presented outside of operating income.  We adopted this ASU on June 1, 2018, which resulted in $0.3 million and $0.6 million of pension income included in Other income (expense), net in the Condensed Consolidated Statement of Operations for the three - and six-month periods ended November 30, 2018, respectively.  The Condensed Consolidated Statement of Operations for the three - and six month periods ended November 30, 2017 were not restated as the non-service cost components of pension expense were not material to fiscal 2018.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASC 606”), which provides guidance for revenue recognition.  ASC 606 superseded the revenue recognition requirements in Accounting Standards Codification (“ASC”) 605, Revenue Recognition, and most industry-specific guidance. 

We adopted ASC 606 on June 1, 2018 using the modified retrospective method.  Under that approach, prior periods have not been restated and continue to be reported under the accounting standards in effect for those periods.  A discussion of our revised accounting policy for revenue recognition is included in Note 3.

We elected to use the practical expedient allowing for the application of ASC 606 only to contracts that were not completed as of June 1, 2018.  We recognized the cumulative effect of initially applying ASC 606 as a decrease of $20.4 million to the opening balance of retained earnings as of June 1, 2018.  The impact of the adoption of ASC 606 on our Condensed Consolidated Balance Sheet was as follows:

	As of		ASC 606		As of
	May 31, 2018		Adjustments		June 1, 2018
Accounts receivable, net	$	202.0	$	(31.4)	$	170.6
Inventories		460.7		(17.3)		443.4
Contract assets–current		—		49.6		49.6
Other current assets		26.2		(0.9)		25.3
Other non-current assets		118.9		(19.0)		99.9
Accrued liabilities		138.3		9.1		147.4
Deferred tax liabilities		15.7		(6.6)		9.1
Other liabilities and deferred income		62.2		(1.1)		61.1
Retained earnings		733.2		(20.4)		712.8

The adoption of ASC 606 impacted us in three primary areas.  First, we have certain contracts in which revenue is recognized using the percentage of completion method over the expected term of the contract.  Under ASC 606, the contract term used for revenue recognition purposes was shortened to exclude any unexercised customer option years or incorporate customer rights to terminate the contract without significant penalty as we do not have any enforceable rights or obligations prior to the exercise of the underlying option.  The impact of this change as of June 1, 2018 resulted in the elimination of certain deferred costs and the establishment of accrued liabilities reflecting our estimated obligations under the contracts.  For this change, we recognized a decrease of $22.1 million to the opening balance of retained earnings as of June 1, 2018.

Second, we have contracts under which we perform repair services on customer-owned assets whereby the customer simultaneously receives the benefits of the repair.  These contracts also transitioned to an over time revenue recognition model as of June 1, 2018 compared to our prior policy of recognizing revenue at the time of shipment.  The impact of this change as of June 1, 2018 resulted in the elimination of certain inventory and accounts receivable amounts and the establishment of a contract asset reflecting the over time revenue recognition treatment.  For this change, we recognized an increase of $1.3 million to the opening balance of retained earnings as of June 1, 2018.  

Third, we have certain contracts under which we manufacture products with no alternative use as the customer owns the underlying intellectual property and we have an enforceable right to payment from the customer.  As a result, we now recognize revenue for these contracts over time as opposed to at the time of shipment, which was our policy prior to June 1, 2018.  The impact of this change as of June 1, 2018 resulted in the elimination of certain inventory amounts and the establishment of a contract asset reflecting the over time revenue recognition treatment.  For this change, we recognized an increase of $0.4 million to the opening balance of retained earnings as of June 1, 2018.

The impact of the ASC 606 adoption on our Condensed Consolidated Balance Sheet as of November 30, 2018 and our Condensed Consolidated Statement of Operations for the three - and six-month periods ended November 30, 2018 was as follows:

					Balances

Income from continuing operations		30.1		(1.6)		28.5

Excluding the ASC 606 adjustments from our reported results for the six-month period ended November 30, 2018, our Condensed Consolidated Statement of Cash Flows would include the changes of asset and liability accounts described above, with no impact on our net cash used in operating activities.

New Accounting Pronouncements Not Yet Adopted

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 and is required to be adopted using a modified retrospective approach. The new standard provides us an option to recognize the cumulative effect adjustment on retained earnings as of June 1, 2019 or as of the beginning of the earliest period presented.  We are in the preliminary phases of our assessment  of this ASU and continue to gather information on our lease population and  portfolio.  We are also considering the terms and conditions of our other arrangements that could meet the definition of a lease and designing and implementing new processes and controls, including information technology tools.  While this assessment continues, we have not yet selected a transition date nor have we determined the effect of this ASU on our consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.  This ASU permits the reclassification of tax effects stranded in accumulated other comprehensive income to retained earnings as a result of the Tax Reform Act.  This new standard will be effective for us beginning June 1, 2019 with early adoption permitted.  We are currently evaluating the impact of this new standard on our consolidated financial statements.

Discontinued Operations

Discontinued Operations

Note 2 – Discontinued Operations

During the third quarter of fiscal 2018, we decided to pursue the sale of our Contractor-Owned, Contractor-Operated (“COCO”) business previously included in our Expeditionary Services segment.  Due to this strategic shift, the assets, liabilities, and results of operations of our COCO business have been reported as discontinued operations for all periods presented.  Goodwill was allocated to this business based on its relative fair value to the reporting unit. The fair value of the reporting unit was determined based on a combination of the expected net proceeds upon sale and a discounted cash flow analysis. As the fair value of the COCO business was below its carrying value, a goodwill impairment charge of $9.8 million, representing the estimated loss on disposal, was recorded in the third quarter of fiscal 2018.

Our COCO business completed certain contracts in the second quarter of fiscal 2018.  As the aircraft supporting these contracts were not placed on new contracts combined with the continued decline in operational tempo within the U.S. Department of Defense and an excess supply of aircraft assets in the market, we determined there was an impairment triggering event and tested the recoverability of our COCO assets. As a result, we recognized impairment and other charges of $54.2 million in the second quarter of fiscal 2018. The fair value of the aircraft and related assets was based on available market data for similar assets.

The COCO business is available for immediate sale and we continue to actively market the COCO business at a reasonable price in relation to its fair value. We expect a sale of the COCO business to be completed before the end of fiscal 2019.

No amounts for general corporate overhead or interest expense were allocated to discontinued operations during the periods presented.  Unless otherwise noted, amounts and disclosures throughout these Notes to Consolidated Financial Statements relate to our continuing operations. 

Operating results for discontinued operations were comprised of the following:

	Three Months Ended				Six Months Ended
	November 30,				November 30,
	2018		2017		2018		2017

Revenue Recognition

Revenue recognition

Note 3 – Revenue Recognition

Revenue is measured based on a consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer.

Our unit of accounting for revenue recognition is a performance obligation included in our customer contracts.  A performance obligation reflects the distinct good or service that we must transfer to a customer.  At contract inception, we evaluate if the contract should be accounted for as a single performance obligation or if the contract contains multiple performance obligations.  In some cases, our contract with the customer is considered one performance obligation as it includes factors such as whether the good or service being provided is significantly integrated with other promises in the contract, whether the service provided significantly modifies or customizes another good or service or whether the good or service is highly interdependent or interrelated.  If the contract has more than one performance obligation, the Company determines the standalone price of each distinct good or service underlying each performance obligation and allocates the transaction price based on their relative standalone selling prices.

The transaction price of a contract, which can include both fixed and variable amounts, is allocated to each performance obligation identified.  Some contracts contain variable consideration, which could include incremental fees or penalty provisions related to performance.  Variable consideration that can be reasonably estimated based on current assumptions and historical information is included in the transaction price at the inception of the contract but limited to the amount that is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. Variable consideration that cannot be reasonably estimated is recorded when known.

Our performance obligations are satisfied over time as work progresses or at a point in time based on transfer of control of products and services to our customers.  The majority of our sales from products are recognized at a point in time upon transfer of control to the customer, which generally occurs upon shipment.  In connection with certain sales of products, we also provide logistics services, which include inventory management, replenishment, and other related services.  The price of such services is generally included in the price of the products delivered to the customer, and revenues are recognized upon delivery of the product, at which point, the customer has obtained control of the product.  We do not account for these services separate from the related product sales as the services are inputs required to fulfill part orders received from customers.

For our performance obligations that are satisfied over time, we measure progress in a manner that depicts the performance of transferring control to the customer. As such, we utilize the input method of cost-to-cost to recognize revenue over time as this depicts when control of the promised goods or services are transferred to the customer.  Revenue is recognized based on the relationship of actual costs incurred to date to the estimated total cost at completion of the performance obligation.  We are required to make certain judgments and estimates, including estimated revenues and costs, as well as inflation and the overall profitability of the arrangement.  Key assumptions involved include future labor costs and efficiencies, overhead costs, and ultimate timing of product delivery.  Differences may occur between the judgments and estimates made by management and actual program results.

Changes in estimates and assumptions related to our arrangements accounted for using the cost-to-cost method are recorded using the cumulative catch-up method of accounting.  These changes are primarily adjustments to the estimated profitability for our long-term, power-by-the-hour programs where we provide component inventory management and repair services.

For the three-month period ended November 30, 2018, we recognized favorable cumulative catch-up adjustments of $3.1 million. For the three-month period ended November 30, 2017, we recognized favorable and unfavorable adjustments of $1.0 million and $0.6 million, respectively. When considering these adjustments on a net basis, we recognized net favorable adjustments of $3.1 million and $0.4 million in the three-month periods ended November 30, 2018 and 2017, respectively.

For the six-month period ended November 30, 2018, we recognized favorable and unfavorable cumulative catch-up adjustments of $3.8 million and $0.5 million, respectively. For the six-month period ended November 30, 2017, we recognized favorable and unfavorable adjustments of $1.0 million and $0.6 million, respectively. When considering these adjustments on a net basis, we recognized net favorable adjustments of $3.3 million and $0.4 million in the six-month periods ended November 30, 2018 and 2017, respectively.

Under most of our U.S. government contracts, if the contract is terminated for convenience, we are entitled to payment for items delivered and fair compensation for work performed, the costs of settling and paying other claims, and a reasonable profit on the costs incurred or committed.

We have elected to use certain practical expedients permitted under ASC 606.  Shipping and handling fees and costs incurred associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of sales in our Condensed Consolidated Statement of Operations, and are not considered a performance obligation to our customers.  Our reported sales on our Condensed Consolidated Statement of Operations are net of any sales or related non-income taxes.  We also utilize the “as invoiced” practical expedient in certain cases where performance obligations are satisfied over time and the invoiced amount corresponds directly with the value we are providing to the customer.

Contract Assets and Liabilities

The timing of revenue recognition, customer billings, and cash collections results in a contract asset or contract liability at the end of each reporting period.  Contract assets consist of unbilled receivables or costs incurred where revenue recognized over time using the cost-to-cost model exceeds the amounts billed to customers.  Contract liabilities include advance payments and billings in excess of revenue recognized. Certain customers make advance payments prior to the satisfaction of our performance obligations on the contract.  These amounts are recorded as contract liabilities until such performance obligations are satisfied, either over time as costs are incurred or at a point in time when deliveries are made.  Contract assets and contract liabilities are determined on a contract-by-contract basis.

Net contract assets and liabilities are as follows:

	November 30,		June 1,
	2018		2018		Change
Contract assets – current	$	63.0	$	49.6	$	13.4
Contract assets – non-current		21.3		12.9		8.4
Contract liabilities –  current		(9.3)		(9.4)		0.1
Contract liabilities– non-current		(68.3)		(33.0)		(35.3)
Net contract assets	$	6.7	$	20.1	$	(13.4)

Contract assets – non-current is reported within Other non-current assets, Contract liabilities – current is reported within Accrued Liabilities, and Contract liabilities – non-current is reported within Other liabilities and deferred income on our Condensed Consolidated Balance Sheet.  Changes in contract assets and contract liabilities primarily result from the timing difference between our performance of services and payments from customers.  For the three- and six-month periods ended November 30, 2018, we recognized revenue of $76.4 million and $156.5 million that was previously included in the beginning balance of contract liabilities.

In the three-month period ended November 30, 2018, we recognized a provision for doubtful accounts of $12.4 million related to the bankruptcy of a European airline customer.  The provision included impairment of non-current contract assets of $7.6 million, allowance for doubtful accounts of $3.3 million, and other liabilities of $1.5 million.

Remaining Performance Obligations

As of November 30, 2018, we had approximately $1.3 billion of remaining performance obligations, also referred to as firm backlog, which excludes unexercised contract options and potential orders under our indefinite-delivery, indefinite-quantity (IDIQ) contracts.  We expect that approximately 40% of this backlog will be recognized as revenue over the next 12 months with the majority of the remainder recognized over the next three years.  The amount of remaining performance obligations that is expected to be recognized as revenue beyond 12 months primarily relates to our long-term, power-by-the-hour programs where we provide component inventory management and repair services.

Note 7 – Sale of Receivables

On February 23, 2018, we entered into a Purchase Agreement with Citibank N.A. (“Purchaser”) for the sale, from time to time, of certain accounts receivable due from certain customers (the “Purchase Agreement”).  Under the Purchase Agreement, the maximum amount of receivables sold is limited to $150 million.  The term of the Purchase Agreement runs through February 22, 2019; however, the Purchase Agreement may also be terminated earlier under certain circumstances.  The term of the Purchase Agreement shall be automatically extended for annual terms unless either party provides advance notice that they do not intend to extend the term.

We have no retained interests in the sold receivables, other than limited recourse obligations in certain circumstances, and only perform collection and administrative functions for the Purchaser.  We account for these receivable transfers as sales under ASC 860, Transfers and Servicing, and de-recognize the sold receivables from our Consolidated Balance Sheet.

During the six- month period ended November 30, 2018, we sold $351.0 million of receivables under the Purchase Agreement and remitted $327.5 million to the Purchaser on their behalf.  During fiscal 2018, we sold $239.6 million of receivables under the Purchase Agreement and remitted $167.9 million to the Purchaser on their behalf.  As of November 30, 2018 and May 31, 2018, we had collected cash of $15.0 million and $10.5 million, respectively, which was not yet remitted to the Purchaser and was classified as Restricted cash on our Condensed Consolidated Balance Sheet.  During the three- and six- month periods ended November 30, 2018, we incurred discounts on the sale of our receivables of $0.6 million and $1.0 million, respectively, which were recognized as an expense in Other income, net on our Condensed Consolidated Statements of Operations.

On October 18, 2017, we entered into a Credit Agreement with the Canadian Imperial Bank of Commerce, as lender (the “Credit Agreement”). The Credit Agreement provided a Canadian $31 million term loan with the proceeds used to fund the acquisition of two maintenance, repair, and overhaul (“MRO”)  facilities in Canada from Premier Aviation. The term loan is due in full at the expiration of the Credit Agreement on November 1, 2021 unless terminated earlier pursuant to the terms of the Credit Agreement.  Interest is payable monthly on the term loan at the offered fluctuating Canadian Dollar Offer Rate plus 125 to 225 basis points based on certain financial measurements if a Bankers’ Acceptances loan, or at the offered fluctuating Prime Rate plus 25 to 125 basis points based on certain financial measurements, if a Prime Rate loan.

Our financing arrangements also require us to comply with leverage and interest coverage ratios, maintain a minimum net working capital level, and comply with certain affirmative and negative covenants, including those relating to financial reporting and notification, payment of indebtedness, cash dividends, taxes and other obligations, compliance with applicable laws, and limitations on additional liens, indebtedness, acquisitions, investments and disposition of assets.  The Revolving Credit Facility also requires our significant domestic subsidiaries, and any subsidiaries that guarantee our other indebtedness, to provide a guarantee of payment under the Revolving Credit Facility.  At November 30, 2018, we were in compliance with the financial and other covenants in our financing agreements.

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 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 six-month periods ended November 30, 2018 and 2017 is as follows:

	Three Months Ended				Six Months Ended

The potential dilutive effect of 290,000 shares relating to stock options was excluded from the computation of weighted average common shares outstanding -- diluted for both the three- and six-month periods ended November 30, 2018 as the shares would have been anti-dilutive.  At November 30, 2017, the average market price of our common shares was in excess of the exercise prices of all of our outstanding options.

Business Segment Information

Note 12 – 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 operating segments: Aviation Services comprised of supply chain and MRO activities and Expeditionary Services comprised of manufacturing activities. 

In the first quarter of fiscal 2019, we re-aligned the composition of our operating segments to leverage the full breadth of our operational expertise in Aviation Services.  Our government-owned, contractor-operated business, which includes the INL/A WASS program, was previously included in our Expeditionary Services segment and is now reported within our Aviation Services segment for all periods presented.

The Aviation Services segment consists of aftermarket support and services offerings that provide spare parts 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, customer fleet management and operations, and aircraft component repair management services.  The segment also includes repair, maintenance and overhaul of aircraft, landing gear and components.  Cost of sales consists principally of the cost of product, direct labor, and overhead.

The Expeditionary Services segment consists of primarily manufacturing operations with sales derived from the design and manufacture of pallets, shelters, and containers used to support the U.S. military’s requirements for a mobile and agile force including engineering, design, and system integration services for specialized command and control systems.  This segment also designs and manufactures advanced composite materials for commercial, business and military aircraft.  Cost of sales consists principally of the cost of material to manufacture products, direct labor and overhead.

The accounting policies for the segments are the same as those described in Note 1 of Notes to Consolidated Financial Statements included in our annual report on Form 10-K for the year ended May 31, 2018 except for our revised accounting policy for revenue recognition.  We adopted ASC 606 on June 1, 2018 and our revised accounting policy is further described in Note 3. 

Our chief operating decision making officer (Chief Executive Officer) evaluates performance based on the operating 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. 

Selected financial information for each segment is as follows:
