Basis of Presentation
Basis of Presentation	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 ASC 606 Excluding As Reported Adjustments ASC 606 Accounts receivable, net $ 218.6 $ 46.8 $ 265.4 Contract assets 63.0 (63.0) — Inventories 495.0 20.1 515.1 Other current assets 33.0 0.6 33.6 Other non-current assets 85.8 21.5 107.3 Accrued liabilities 114.4 (5.0) 109.4 Deferred tax liabilities 10.5 6.6 17.1 Other liabilities and deferred income 95.0 5.6 100.6 Retained earnings 729.6 18.8 748.4 Three Months Ended November 30, 2018 Balances ASC 606 Excluding As Reported Adjustments ASC 606 Sales $ 493.3 $ (0.4) $ 492.9 Cost of sales 415.0 (1.5) 413.5 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 Balances ASC 606 Excluding As Reported Adjustments ASC 606 Sales $ 959.6 $ (5.2) $ 954.4 Cost of sales 810.1 (3.1) 807.0 Gross profit 149.5 (2.1) 147.4 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.

Discontinued Operations

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 Sales $ 22.2 $ 29.1 $ 42.2 $ 70.4 Cost of sales (25.4) (27.4) (47.7) (65.8) Asset impairments — (54.2) — (54.2) Selling, general and administrative expenses (2.3) (3.4) (4.8) (7.0) Loss from discontinued operations before provision for income tax benefit (5.5) (55.9) (10.3) (56.6) Provision for income tax benefit (1.3) (20.1) (2.3) (20.4) Loss from discontinued operations $ (4.2) $ (35.8) $ (8.0) $ (36.2) The carrying amounts of the major classes of assets and liabilities for our discontinued operations are as follows: November 30, May 31, 2018 2018 Inventory, rotable assets, and equipment $ 93.5 $ 106.1 Accounts receivable, net 13.1 14.7 Other assets 3.3 4.2 Assets of discontinued operations $ 109.9 $ 125.0 Liabilities of discontinued operations $ 24.6 $ 25.0

Revenue Recognition

Revenue Recognition	6 Months Ended
	Nov. 30, 2018
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. Disaggregation of Revenue Sales across the major customer markets for each of our operating segments for the three- and six-month periods ended November 30, 2018 and 2017 were as follows: Three Months Ended Six Months Ended November 30, November 30, 2018 2017 2018 2017 Aviation Services: Commercial $ 325.5 $ 303.4 $ 632.2 $ 600.2 Government and defense 137.4 88.3 269.1 162.8 $ 462.9 $ 391.7 $ 901.3 $ 763.0 Expeditionary Services: Commercial $ 8.0 $ 9.2 $ 16.5 $ 17.5 Government and defense 22.4 19.7 41.8 38.0 $ 30.4 $ 28.9 $ 58.3 $ 55.5 Sales by geographic region for the three- and six month periods ended November 30, 2018 and 2017 were as follows: Three Months Ended Six Months Ended November 30, November 30, 2018 2017 2018 2017 Aviation Services: North America $ 331.7 $ 268.0 $ 651.2 $ 525.5 Europe/Africa 83.5 86.6 164.5 155.2 Other 47.7 37.1 85.6 82.3 $ 462.9 $ 391.7 $ 901.3 $ 763.0 Expeditionary Services: North America $ 29.2 $ 27.0 $ 54.9 $ 51.7 Europe/Africa 1.0 1.9 2.7 3.7 Other 0.2 — 0.7 0.1 $ 30.4 $ 28.9 $ 58.3 $ 55.5

Sale of Receivables
Sale of Receivables	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.

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.

Earnings per Share
Earnings per Share	Note 9 – Earnings per Share The computation of basic earnings per share is based on the weighted average number of common shares outstanding during each period. The computation of diluted earnings per share is based on the weighted average number of common shares outstanding during the period plus, when their effect is dilutive, incremental shares consisting of shares subject to stock options 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 November 30, November 30, 2018 2017 2018 2017 Basic and Diluted EPS: Income from continuing operations $ 11.2 $ 13.2 $ 30.1 $ 24.2 Less income attributable to participating shares (0.1) (0.1) (0.1) (0.1) Income from continuing operations attributable to common shareholders 11.1 13.1 30.0 24.1 Loss from discontinued operations attributable to common shareholders (4.2) (35.8) (8.0) (36.2) Net income (loss) attributable to common shareholders for earnings per share $ 6.9 $ (22.7) $ 22.0 $ (12.1) Weighted Average Shares: Weighted average common shares outstanding – basic 34.6 34.0 34.6 34.1 Additional shares from the assumed exercise of stock options 0.4 0.5 0.5 0.4 Weighted average common shares outstanding – diluted 35.0 34.5 35.1 34.5 Earnings (Loss) per share – basic: Earnings from continuing operations $ 0.32 $ 0.39 $ 0.87 $ 0.71 Loss from discontinued operations (0.12) (1.05) (0.23) (1.06) Earnings (Loss) per share – basic and diluted $ 0.20 $ (0.66) $ 0.64 $ (0.35) Earnings (Loss) per share – diluted: Earnings from continuing operations $ 0.32 $ 0.38 $ 0.85 $ 0.70 Loss from discontinued operations (0.12) (1.04) (0.23) (1.05) 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.

Business Segment Information
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: Three Months Ended Six Months Ended November 30, November 30, 2018 2017 2018 2017 Sales: Aviation Services $ 462.9 $ 391.7 $ 901.3 $ 763.0 Expeditionary Services 30.4 28.9 58.3 55.5 $ 493.3 $ 420.6 $ 959.6 $ 818.5 Three Months Ended Six Months Ended November 30, November 30, 2018 2017 2018 2017 Gross profit: Aviation Services $ 74.9 $ 66.0 $ 142.0 $ 123.8 Expeditionary Services 3.4 4.7 7.5 8.5 $ 78.3 $ 70.7 $ 149.5 $ 132.3 The following table reconciles segment gross profit to income from continuing operations before provision for income taxes: Three Months Ended Six Months Ended November 30, November 30, 2018 2017 2018 2017 Segment gross profit $ 78.3 $ 70.7 $ 149.5 $ 132.3 Selling, general and administrative (49.1) (48.8) (97.3) (93.1) Provision for doubtful accounts (12.4) (0.1) (13.0) (0.3) Other income (expense), net (0.2) — 0.2 — Interest expense (2.5) (1.9) (4.6) (3.6) Interest income 0.1 0.1 0.6 0.1 Income from continuing operations before provision for income taxes $ 14.2 $ 20.0 $ 35.4 $ 35.4
