Air Transport Services Group, Inc. is a holding company whose principal subsidiaries include an aircraft leasing company and two U.S. certificated airlines. The Company provides airline operations, aircraft leases, aircraft maintenance and other support services primarily to the cargo transportation and package delivery industries. Through the Company's subsidiaries, it offers a range of complementary services to delivery companies, freight forwarders, airlines and government customers.

The Company's leasing subsidiary, Cargo Aircraft Management, Inc. (“CAM”), leases aircraft to each of the Company's airlines as well as to non-affiliated airlines and other lessees. The airlines, ABX Air, Inc. (“ABX”) and Air Transport International, Inc. (“ATI”), each have the authority, through their separate U.S. Department of Transportation ("DOT") and Federal Aviation Administration ("FAA") certificates, to transport cargo worldwide. ATI provides passenger transportation, primarily to the U.S. Military, using "combi" aircraft, which are certified to carry passengers as well as cargo on the main deck.

The Company provides air transportation services to a concentrated base of customers. The Company provides a combination of aircraft, crews, maintenance and insurance services for a customer's transportation network through "CMI" and "ACMI" agreements and through charter contracts in which aviation fuel is also included. In addition to its airline operations and aircraft leasing services, the Company sells aircraft parts, provides aircraft maintenance and modification services, equipment maintenance services, and operates mail and package sorting facilities.

The accompanying unaudited condensed interim consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America and such principles are applied on a basis consistent with the financial statements reflected in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 filed with the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the rules and regulations promulgated by the SEC related to interim financial statements. In the opinion of management, the accompanying financial statements contain all adjustments, including normal recurring adjustments, necessary for the fair presentation of the Company’s results of operations and financial position for the periods presented. Due to seasonal fluctuations, among other factors common to the air cargo industry, the results of operations for the periods presented are not necessarily indicative of the results of operations to be expected for the entire year or any interim period. The preparation of consolidated financial statements requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements. The accounting estimates reflect the best judgment of management, but actual results could differ materially from those estimates.

The accompanying condensed consolidated financial statements include the accounts of Air Transport Services Group, Inc. and its wholly-owned subsidiaries. Investments in an affiliate in which the Company has significant influence but does not exercise control are accounted for using the equity method of accounting. Using the equity method, the Company’s share of the nonconsolidated affiliate's income or loss is recognized in the consolidated statement of earnings and cumulative post-acquisition changes in the investment are adjusted against the carrying amount of the investment. Inter-company balances and transactions are eliminated.

ASU 2014-09 is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017 with earlier adoption permitted for reporting periods beginning after December 15, 2016. ASU 2014-09 may be applied using either a full retrospective approach, under which all years included in the financial statements will be presented under the revised guidance, or a modified retrospective approach, under which financial statements will be prepared under the revised guidance for the year of adoption, but not for prior years. Under the latter method, entities would recognize a cumulative catch-up adjustment to the opening balance of retained earnings at the effective date for contracts that still require performance by the entity, and disclose all line items in the year of adoption as if they were prepared under the old revenue guidance.

The Company plans to adopt the standard using the modified retrospective method. The Company is currently evaluating the effect the standard is expected to have on the Company's consolidated financial position, results of operations, cash flows and related disclosures. The evaluation includes each of the five steps identified in the ASU 2014-09 revenue recognition model, which are as follows: 1) identify the contract with the customer; 2) identify the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance obligations; and 5) recognize revenue when (or as) performance obligations are satisfied. The Company's lease contracts within the scope of ASC 840, Leases, are specifically excluded from ASU 2014-09. As the Company completes its evaluation of this new standard, new information may arise that could change the Company's current understanding of the impact to revenue and expense recognized. Management is monitoring recent industry activities and other guidance provided by regulators, standards setters, and the accounting profession that may impact the Company's recognition of revenue.

In July 2015, FASB issued ASU "Inventory (Topic 330): Simplifying the Measurement of Inventory" ("ASU 2015-11"). ASU 2015-11 more closely aligns the measurement of inventory in GAAP with the measurement of inventory in International Financial Reporting Standards ("IFRS"). The amendment in ASU 2015-11 is for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. The amendment should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company does not expect the impact of adopting ASU 2015-11 to be material to the Company's financial statements and related disclosures.

In March 2017, the FASB issued ASU "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" (ASU 2017-07"). ASU 2017-07 requires an employer to report the service cost component of retiree benefits in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost would be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. The standard is effective for annual periods beginning after December 15, 2017 and should be applied retrospectively. The Company anticipates the standard will impact the Operating Income subtotal as reported in the Company's Consolidated Statement of Operations by excluding interest expense, investment returns and other non service cost components of retiree benefit expenses. Information about interest expense, investment returns and other components of retiree benefit expenses can be found in Note I.

In February 2016, the FASB issued ASU "Leases (Topic 842)" ("ASU 2016-02"), which will require the recognition of right to-use-assets and lease liabilities for leases previously classified as operating leases by lessees. The standard will take effect for annual reporting periods beginning after December 15, 2018, including interim reporting periods. Early application will be permitted for all entities. In addition, the FASB has decided to require a lessee to apply a modified retrospective transition approach for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements (the date of initial application). The modified retrospective approach would not require any transition accounting for leases that expired before the date of initial application. The FASB decided to not permit a full retrospective transition approach. The Company is currently evaluating the impact of the standard on its financial statements and disclosures.

In August 2016, the FASB issued ASU, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments" ("ASU 2016-15"). ASU 2016-15 clarifies how cash receipts and cash payments in certain transactions are presented and classified in the statement of cash flows. The effective date of this update is for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The update requires retrospective application to all periods presented but may be applied prospectively if retrospective application is impracticable. The Company is currently evaluating the impact of the adoption of the standard on its financial statements and disclosures.

In November 2016, the FASB issued ASU "Statement of Cash Flows (Topic 230): Restricted Cash" ("ASU 2016-18"). ASU 2016-18 requires that the statement of cash flows explain the changes in the combined total of restricted and unrestricted cash balance. Amounts generally described as restricted cash or restricted cash equivalents will be combined with unrestricted cash and cash equivalents when reconciling the beginning and end of period balances on the statement of cash flows. Further, the ASU requires a reconciliation of balances from the statement of cash flows to the balance sheet in situations in which the balance sheet includes more than one line item of cash, cash equivalents, and restricted cash. Companies will also be disclosing the nature of the restrictions. ASU 2016-18 is effective for financial statements issued for fiscal years beginning after December 15, 2017. The Company is currently evaluating the impact of the standard on its financial statements and disclosures.

In January 2017, the FASB issued ASU "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" ("ASU 2017-04"). ASU 2017-04 will simplify the subsequent measurement of goodwill by eliminating the second step from the goodwill impairment test. ASU 2017-04 would require applying a one-step quantitative test and recording the amount of goodwill impairment as the excess of the reporting unit's carrying value over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. ASU 2017-04 does not amend the optional qualitative assessment of goodwill impairment. The amendments in ASU 2017-04 are effective for annual or any interim goodwill impairment tests for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact of the standard on its financial statements and disclosures.

The Company has had long term contracts with DHL Network Operations (USA), Inc. and its affiliates ("DHL") since August 2003. Revenues from aircraft leases and related services performed for DHL were approximately 25% and 25% of the Company's consolidated revenues from continuing operations for the three and nine month periods ending September 30, 2017, respectively compared to 34% and 35% for the corresponding periods of 2016. The Company’s balance sheets include accounts receivable with DHL of $3.7 million and $7.3 million as of September 30, 2017 and December 31, 2016, respectively.

The Company leases 16 Boeing 767 aircraft to DHL under both long-term and short-term lease agreements. Under a separate crew, maintenance and insurance (“CMI”) agreement, the Company operates Boeing 767 aircraft that DHL leases from the Company. Pricing for services provided through the CMI agreement is based on pre-defined fees, scaled for the number of aircraft operated and the number of flight crews provided to DHL for its U.S. network. The Company provides DHL with scheduled maintenance services for aircraft that DHL leases. The Company also provides Boeing 767 and Boeing 757 air cargo transportation services for DHL through additional ACMI agreements in which the Company provides the aircraft, crews, maintenance and insurance under a single contract. Revenues generated from the ACMI agreements are typically based on hours flown and a contracted minimum number of block hours. The Company also provides ground equipment, such as power units, air starts and related maintenance services to DHL under separate agreements.

The Company has been providing freighter aircraft and services for cargo handling and logistical support for Amazon Fulfillment Services, Inc. ("AFS"), a subsidiary of Amazon.com, Inc. ("Amazon") since September 2015. On March 8, 2016, the Company entered into an Air Transportation Services Agreement (the “ATSA”) with AFS pursuant to which CAM will lease 20 Boeing 767 freighter aircraft to AFS, including 12 Boeing 767-200 freighter aircraft for

a term of five years and eight Boeing 767-300 freighter aircraft for a term of seven years. The ATSA, which has a term of five years, also provides for the operation of those aircraft by the Company’s airline subsidiaries, and the performance of hub and gateway services by the Company's subsidiary LGSTX Services Inc. ("LGSTX"). CAM owns all of the Boeing 767 aircraft that are leased and operated under the ATSA. The ATSA became effective on April 1, 2016. As of September 30, 2017, the Company has met its 20 aircraft commitment.

Revenues from aircraft leases and related services performed for AFS comprised approximately 45% and 42% of the Company's consolidated revenues from continuing operations for the three and nine month periods ending September 30, 2017 respectively, compared to 31% and 24% for the corresponding periods of 2016. The Company’s balance sheets include accounts receivable with AFS of $25.9 million and $24.6 million as of September 30, 2017 and December 31, 2016, respectively.

In conjunction with the execution of the ATSA, the Company and Amazon entered into an Investment Agreement and a Stockholders Agreement on March 8, 2016. The Investment Agreement calls for the Company to issue warrants in three tranches which will grant Amazon the right to acquire up to 19.9% of the Company’s outstanding common shares as described below. The first tranche of warrants, issued upon execution of the Investment Agreement, granted Amazon the right to purchase approximately 12.81 million ATSG common shares, with the right to purchase 7.69 million common shares vesting upon issuance on March 8, 2016, and the right to purchase the remaining 5.12 million common shares vesting as the Company delivered additional aircraft leased under the ATSA, or as the Company achieved specified revenue targets in connection with the ATSA. The second tranche of warrants grants Amazon a right to purchase approximately 1.59 million ATSG common shares, and will be issued and vest on March 8, 2018. The third tranche of warrants will be issued and vest on September 8, 2020. The third tranche of warrants will grant Amazon the right to purchase such additional number of ATSG common shares as is necessary to bring Amazon’s ownership to 19.9% of the Company’s pre-transaction outstanding common shares measured on a GAAP-diluted basis, adjusted for share issuances and repurchases by the Company following the date of the Investment Agreement and after giving effect to the warrants granted. The exercise price of the warrants will be $9.73 per share, which represents the closing price of ATSG’s common shares on February 9, 2016. Each of the three tranches of warrants will be exercisable in accordance with its terms through March 8, 2021. The Company anticipates making available the common shares required for the underlying warrants through a combination of share repurchases and the issuance of additional shares.

The Company’s accounting for the warrants has been determined in accordance with the financial reporting guidance for equity-based payments to non-employees and for financial instruments. During the first nine months of 2017, 3.8 million additional warrants vested in conjunction with the execution of six aircraft leases during 2017. As of September 30, 2017, the Company's liabilities reflected 14.90 million warrants having a fair value of $15.44 per share. As of September 30, 2017, the re-measurements of the warrants to fair value resulted in a third quarter non-operating loss of $35.0 million before the effect of income taxes.

A substantial portion of the Company's revenues is also derived from the U.S. Military. The U.S. Military awards flights to U.S. certificated airlines through annual contracts and through temporary "expansion" routes. Revenues from services performed for the U.S. Military were approximately 7% and 7% of the Company's total revenues from continuing operations for the three and nine month periods ending September 30, 2017, respectively, compared to 12% and 13% for the corresponding periods of 2016. The Company's balance sheets included accounts receivable with the U.S. Military of $5.3 million and $7.0 million as of September 30, 2017 and December 31, 2016, respectively.

On December 30, 2016, the Company purchased 100% of the outstanding stock of Pemco World Air Services Inc., ("Pemco") for cash consideration in a debt-free acquisition. The purchase price has been allocated to tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess purchase price over the estimated fair value of net assets acquired was recorded as goodwill

and reflects the strategic value of marketing Pemco's aircraft conversion capabilities and current aircraft hangar operations with the Company's comprehensive set of air transportation solutions. Identified intangible assets include Supplemental Type Certificates ("STCs") granting approval by the FAA for Pemco to market and complete certain aircraft modifications. The Company is in the process of refining its estimates of certain assets including goodwill and intangible assets, therefore the allocation of purchase price is preliminary at this time. The consolidated statements of operations include the revenues and expenses for Pemco for the periods after its acquisition by the Company. The consolidated statements of operations reflect the reclassification of certain previously reported operating expenses to conform to the current presentation.

In January 2014, the Company acquired a 25 percent equity interest in West Atlantic AB of Gothenburg, Sweden ("West"). West, through its two airlines, Atlantic Airlines Ltd. and West Air Sweden AB, operates a fleet of aircraft on behalf of European regional mail carriers and express logistics providers. The airlines operate a combined fleet of British Aerospace ATPs, Bombardier CRJ-200-PFs, and Boeing 767 and 737 aircraft. West leases three Boeing 767 aircraft from the Company. The Company accounts for West using the equity method of accounting. The Company’s carrying value of West was $7.9 million and $9.9 million at September 30, 2017 and December 31, 2016, respectively, including $5.5 million of excess purchase price over the Company's fair value of West's net assets in January of 2014. The carrying value is reflected in “Other Assets” in the Company’s consolidated balance sheets.

On August 3, 2017 the Company entered into a joint-venture agreement with Precision Aircraft Solutions, LLC, to develop a passenger-to-freighter conversion program for Airbus A321-200 aircraft. The Company anticipates approval of a supplemental type certificate from the FAA in 2019. The Company expects to make contributions equal to its 49% ownership percentage of the program's total costs over the next two years. The Company accounts for its investment in the joint venture under the equity method of accounting. During the third quarter, the company contributed $6.3 million to the joint venture. The carrying value of the joint venture,reflected in “Other Assets” in the Company’s consolidated balance sheets, was $5.3 million at September 30, 2017.

The Company’s money market funds and interest rate swaps are reported on the Company’s consolidated balance sheets at fair values based on market values from identical or comparable transactions. The fair value of the Company’s money market funds, stock warrant obligations, convertible note, convertible note hedges and interest rate swaps are based on observable inputs (Level 2) from comparable market transactions. The fair value of the stock warrant obligations were determined using a Black-Scholes pricing model which considers the Company’s common stock price and various assumptions, such as the volatility of the Company’s common stock, the expected dividend yield, and the risk-free interest rate. The fair value of the note conversion obligations and the convertible note hedges were estimated using a Black-Scholes pricing model and incorporate the terms and conditions of the underlying financial instruments. The valuations are, among other things, subject to changes in both the Company's credit worthiness and the counter-parties to the instruments as well as change in general market conditions. While the change in fair value of the note conversion obligations and the convertible note hedges are generally expected to move in opposite directions, the net change in any given period may be material.

The fair value of the Company’s fixed and variable debt obligations, based on Level 2 observable inputs, was approximately $12.4 million more than the carrying value, which was $493.2 million at September 30, 2017. As of December 31, 2016, the fair value of the Company’s fixed and variable debt obligations was approximately $0.2 million more than the carrying value, which was $458.7 million. The non-financial assets, including goodwill, intangible assets and property and equipment are measured at fair value on a non-recurring basis.

The Company’s accounting policy for major airframe and engine maintenance varies by subsidiary and aircraft type. The costs for ABX's Boeing 767-200 airframe maintenance are expensed as they are incurred. The costs of major airframe maintenance for the Company's other aircraft are capitalized and amortized over the useful life of the overhaul. Many of the Company's General Electric CF6 engines that power the Boeing 767-200 aircraft are maintained under “power by the hour” and "power by the cycle" agreements with an engine maintenance provider. Further, in May 2017, the Company entered into similar maintenance agreements for certain General Electric CF6 engines that power many of the Company's Boeing 767-300 aircraft. Under these agreements, the engines are maintained by the service provider for a fixed fee per cycle and/or flight hour. As a result, the cost of maintenance for these engines is generally expensed as flights occur. During their term, these maintenance agreements contain provisions for a minimum level of flight activity. Maintenance for the airlines’ other aircraft engines, including those powering Boeing 757 aircraft, are typically contracted to service providers on a time and material basis and the costs of those engine overhauls are capitalized and amortized over the useful life of the overhaul.

The Company executed a syndicated credit agreement ("Senior Credit Agreement") in May 2011 which includes an unsubordinated term loan and a revolving credit facility. Effective March 31, 2017, the Company executed an amendment to the Senior Credit Agreement. The March 2017 amendment extended the maturity of the term loan and revolving facility to May 30, 2022, increased the capacity of the revolving credit facility by $120.0 million to $545.0 million and preserved the accordion feature such that the Company can still draw up to an additional $100.0 million subject to the lenders' consent. Each year, through May 6, 2019, the Company may request a one year extension of the final maturity date, subject to the lenders' consent. In September 2017, the Company executed amendments to the Senior Credit agreement. These amendments increased the revolving credit facility's permitted additional indebtedness to $300.0 million for convertible notes described below. The amendments also increased the amount of dividends the Company can pay and the amount of common stock it can repurchase to $100.0 million during any calendar year, provided the Company's total secured debt to earnings before interest, taxes, depreciation and amortization expenses ("EBITDA") ratio is under 3.00 times, after giving effect to the dividend or repurchase. Under the terms of the Senior Credit Agreement, the Company is required to maintain collateral coverage equal to 125% of the outstanding balances of the term loan and the maximum capacity of the revolving credit facility or 150% of the outstanding balance of the term loan and the total funded revolving credit facility, whichever is less. The minimum collateral coverage which must be maintained is 50% of the outstanding balance of the term loan plus the revolving credit facility commitment which was $545.0 million.

The balances of the unsubordinated term loan are net of debt issuance costs of $0.7 million and $0.6 million for the periods ending September 30, 2017 and December 31, 2016, respectively. Under the terms of the Senior Credit Agreement, interest rates are adjusted quarterly based on the Company's EBITDA, its outstanding debt level and prevailing LIBOR or prime rates. At the Company's current secured debt-to-EBITDA ratio, the LIBOR based financing for the unsubordinated term loan and revolving credit facility bear a variable interest rate of 3.24% and 3.24%, respectively. The Senior Credit Agreement provides for the issuance of letters of credit on the Company's behalf. As of September 30, 2017, the unused revolving credit facility totaled $315.7 million, net of draws of $220.0 million and outstanding letters of credit of $9.3 million.

The aircraft loans are collateralized by two aircraft, and amortize monthly with a balloon payment of approximately 20% with maturities between 2017 and early 2018. Interest rates range from 6.74% to 6.82% per annum payable monthly. The Senior Credit Agreement is collateralized by certain of the Company's Boeing 767 and 757 aircraft that are not collateralized under aircraft loans. The Senior Credit Agreement contains covenants including, among other things, limitations on certain additional indebtedness, guarantees of indebtedness, as well as a total debt to EBITDA ratio and a fixed charge coverage ratio. The Senior Credit Agreement stipulates events of default, including unspecified events that may have material adverse effects on the Company. If an event of default occurs, the Company may be forced to repay, renegotiate or replace the Senior Credit Agreement.

In September 2017, the Company issued $258.8 million aggregate principal amount of 1.125% Convertible Senior Notes due 2024 ("Notes") in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The Notes bear interest at a rate of 1.125% per year payable semi-annually in arrears on April 15 and October 15 each year, beginning April 15, 2018. The Notes mature on October 15, 2024, unless repurchased or converted in

accordance with their terms prior to such date. The Notes are unsecured indebtedness, subordinated to the Company's existing and future secured indebtedness and other liabilities, including trade payables. Conversion of the Notes can only occur upon satisfaction of certain conditions and during certain periods, beginning any calendar quarter commencing after December 31, 2017 and thereafter, until the close of business on the second scheduled trading day immediately preceding the maturity date. Upon the occurrence of certain fundamental changes, holders of the Notes can require the Company to repurchase their notes at the cash repurchase price equal to the principal amount of the notes, plus any accrued and unpaid interest. Until the Company's shareholders increase the number of authorized shares of common stock to cover the full number of shares underlying the Notes, the Company is required to settle conversions solely in cash. If the number of authorized shares is increased, the Notes may be settled in cash, the Company’s common shares or a combination of cash and the Company’s common shares, at the Company’s election. The initial conversion rate is 31.3475 common shares per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $31.90 per common share). If a “make-whole fundamental change” (as defined in the offering circular with the Notes) occurs, the Company will in certain circumstances increase the conversion rate for a specified period of time.

The Company evaluated the conversion features of the Notes under the applicable accounting guidance including ASC 815, "Derivatives and Hedging," and determined that the conversion features require separate accounting as a derivative. At the time of issuance, the fair value of this derivative was recorded on the balance sheet as the note conversion obligations (a long-term liability) and an offsetting discount to the Notes. Until the Company's shareholders increase the number of authorized shares of common stock, the note conversion obligations will be adjusted to reflect its fair value at the end of each quarter. The fair value of the note conversion obligation at issuance was $57.4 million. The fair value of the note conversion obligations at September 30, 2017 was $61.2 million and resulted in a non-operating loss of $3.9 million before the effect of income tax during the third quarter ended September 30, 2017.

In conjunction with the offering of the Notes, the Company purchased convertible note hedges under privately negotiated transactions for $56.1 million. These transactions cover, subject to customary anti-dilution adjustments, the number of the Company’s common shares that initially underlie the Notes, and are expected to reduce the potential equity dilution with respect to our common stock, and/or offset any cash payments in excess of the principal amount due, as the case may be, upon conversion of the Notes. The initial strike price of the convertible note hedges is $31.90 per share. The Company evaluated the convertible note hedges under the applicable accounting guidance, including ASC 815, "Derivatives and Hedging," and determined that the convertible note hedges should be accounted for as derivatives. These derivatives were capitalized on the balance sheet as long-term assets and are adjusted to reflect their fair value at the end of the quarter. The fair value of the convertible note hedges at September 30, 2017 was $60.6 million. As of September 30, 2017, the re-measurement of the convertible note hedges to fair value resulted in a non-operating gain of $4.5 million before the effect of income tax.

In conjunction with the offering of the Notes, the Company also sold warrants to the convertible note hedges counterparties in separate, privately negotiated warrant transactions at a higher strike price and for the same number of the Company’s common shares, subject to customary anti-dilution adjustments. The warrants could have a dilutive effect on the Company’s outstanding common shares and the Company’s earnings per share to the extent that the traded market price of the Company’s common shares exceeds the strike price of the warrants which is $41.35 per share and is subject to certain adjustments under the terms of the warrant transactions. The Company evaluated the warrants under the applicable accounting guidance, including ASC 815 "Derivatives and Hedging," and determined that the warrants meet the definition of a derivative, however, because these warrants have been determined to be indexed to the Company's own stock and meet the criteria for equity classification, they have been recorded in shareholder's equity. In the event these warrants are exercised, the Company has enough authorized and unissued shares for their issuance. The amount paid for these warrants and recorded in Stockholders' Equity in the Company’s consolidated balance sheets was $38.5 million. Taken together, the convertible note hedge and warrant transactions are intended to limit, during Notes conversion events, the dilution of the Company's common shares until the traded market price exceeds $41.35.

The Company's Senior Credit Agreement requires the Company to maintain derivative instruments for protection from fluctuating interest rates, for at least fifty percent of the outstanding balance of the term loan. Accordingly, the Company entered into interest rate swaps. The Company entered into two new interest rate swaps in February 2017 and April 2017, respectively, having an initial value of $39.4 million and $50.0 million, respectively, and forward start dates of June 30, 2017. The Company also entered into a new interest rate swap in July 2017, having an initial value of $75.0 million and a forward start date of December 31, 2017. Under these three new swaps, the Company pays a fixed rate of 1.703%, 1.9% and 1.95%, respectively, and receives a floating rate that resets monthly based on LIBOR. The table below provides information about the Company’s interest rate swaps (in thousands):

The outstanding interest rate swaps are not designated as hedges for accounting purposes. The effects of future fluctuations in LIBOR interest rates on derivatives held by the Company will result in the recording of unrealized gains and losses into the statement of operations. The Company recorded the net loss on derivatives of $0.3 million and net gains on derivatives of $0.1 million for the nine month periods ending September 30, 2017 and 2016, respectively. The asset for outstanding derivatives is recorded in other assets. The liability for outstanding derivatives is recorded in other liabilities and in accrued expenses.

During September 2017, the Company issued convertible debt in the form of the Notes and recorded a long-term liability representing the Note conversion liability. In conjunction with the Notes, the Company purchased convertible note hedges having the same number of the Company’s common shares, 8.1 million shares, and same strike price of $31.90, that underlie the Notes. The convertible note hedges are expected to reduce the potential equity dilution with respect to the Company's common stock, and/or offset any cash payments in excess of the principal amount due, as the case may be, upon conversion of the Notes. The Company recorded a net gain before the effects of income taxes of $0.6 million during the quarter ending September 30, 2017 for the revaluation of the convertible note hedges and the note conversion obligations to fair value. For additional information see Note F, "Debt Obligations " and Note D "Fair Value Measurements."

The Company leases portions of the air park in Wilmington, Ohio, under lease agreements with a regional port authority, the terms of which expire in May of 2019 and June of 2036 with options to extend the leases. The leased facilities include corporate offices, 310,000 square feet of maintenance hangars and a 100,000 square foot component repair shop at the air park. ABX also has the non-exclusive right to use the airport, which includes one active runway, taxi ways and ramp space. The Company also leases and operates a 311,500 square foot, two hangar aircraft maintenance complex in Tampa, Florida. Additionally, the Company leases certain equipment, airport facilities, office space and maintenance facilities at locations outside of the airpark in Wilmington.

The Company has agreements with Israel Aerospace Industries Ltd. ("IAI") for the conversion of Boeing 767 passenger aircraft into a standard configured freighter aircraft. The conversions primarily consist of the installation of a standard cargo door and loading system. At September 30, 2017, the Company was committed to acquire and modify additional Boeing 767-300 passenger aircraft into standard freighter aircraft. In addition to three Boeing 767-300 aircraft that were in the modification process at September 30, 2017, the Company is committed to induct six more aircraft into the freighter modification process through 2018. As of September 30, 2017, the Company's commitments to complete the conversions of aircraft it owns or has the contracts to purchase totaled $124.5 million. Additionally, the Company could incur a cancellation fee for part kits for any aircraft that is not inducted into conversion at IAI.

In September 2015, the Company entered into a joint venture agreement to establish an express cargo airline serving multiple destinations within the People's Republic of China (including Hong Kong, Macau and Taiwan) and surrounding countries, pending governmental approvals. The Company's contributions to the joint venture have been minimal and are expected to remain so over the next several months. Obtaining required governmental approvals for any new airline has since been delayed and as a result, the Company is evaluating alternatives. The Company is seeking to develop other aircraft investments in China by leveraging the relationship developed by Pemco, which provides modified Boeing 737 freighter aircraft in China.

In addition to the foregoing matters, the Company is also a party to legal proceedings, including FAA enforcement actions, in various federal and state jurisdictions from time to time arising out of the operation of the Company's business. The amount of alleged liability, if any, from these proceedings cannot be determined with certainty; however, the Company believes that its ultimate liability, if any, arising from pending legal proceedings, as well as from asserted legal claims and known potential legal claims which are probable of assertion, taking into account established accruals for estimated liabilities, should not be material to our financial condition or results of operations.

ABX sponsors a qualified defined benefit pension plan for ABX crewmembers and a qualified defined benefit pension plan for a major portion of its other ABX employees that meet minimum eligibility requirements. The plans are funded through Company contributions to an invested trust. ABX also sponsors non-qualified defined benefit pension plans for certain employees. These non-qualified plans are unfunded. Employees are no longer accruing benefits under any of the defined benefit pension plans. ABX also sponsors a post-retirement healthcare plan for its ABX crewmembers, which is unfunded. Benefits for covered individuals terminate upon reaching age 65 under the post-retirement healthcare plans.

The accounting and valuation for these post-retirement obligations are determined by prescribed accounting and actuarial methods that consider a number of assumptions and estimates. The selection of appropriate assumptions and estimates is significant due to the long time period over which benefits will be accrued and paid. The long term nature of these benefit payouts increases the sensitivity of certain estimates of our post-retirement costs. The assumptions considered most sensitive in actuarially valuing ABX’s pension obligations and determining related expense amounts are discount rates and expected long term investment returns on plan assets. Additionally, other assumptions concerning retirement ages, mortality and employee turnover also affect the valuations. Actual results and future changes in these assumptions could result in future costs significantly higher than those recorded in our results of operations. Effective December 31, 2016, ABX modified its unfunded, non-pilot retiree medical plan to terminate benefits to all participants. Retired participants were directed to public healthcare exchanges for more flexible and lower cost alternatives. As a result, ABX settled all retiree medical obligations.

On August 30, 2017, the Company transferred investment assets totaling $106.6 million from the pension plan trust to purchase a group annuity contract from Mutual of America Life Insurance Company ("MUA"). The group annuity contract transfers payment obligations for pension benefits owed to certain former, non-pilot retirees of ABX (or their beneficiaries) to MUA. As a result of the transaction, the Company recognized pre-tax settlement charges of $5.3 million to continued operations and $7.6 million to discontinued operations in the third quarter due to the reclassification of $12.9 million of pretax losses from accumulated other comprehensive loss.

The provision for income taxes for interim periods is based on management's best estimate of the effective income tax rate expected to be applicable for the current year, plus any adjustments arising from changes in the estimated amount of taxable income related to prior periods. Income tax expense recorded through September 30, 2017 utilized a projected annualized 39.6% rate applied to year-to-date income. Additionally, the Company recorded discrete tax items for the conversion of employee stock awards during the first quarter of 2017 and the issuance of stock warrants during the first three quarters of 2017, resulting in an effective tax rate of (36.2)%. The final effective tax rate applied to 2017 will depend on the actual amount of pre-tax book results by the Company for the full year, the additional conversions of employee stock awards, issuance of stock warrants and other items.

The Company has operating loss carryforwards for U.S. federal income tax purposes. Management expects to utilize the loss carryforwards to offset federal income tax liabilities in the future. Due to the Company's deferred tax assets, including its loss carryforwards, management does not expect to pay federal income taxes until 2019 or later. The Company may, however, be required to pay alternative minimum taxes and certain state and local income taxes before then.

The Company's Board of Directors has granted stock incentive awards to certain employees and board members pursuant to a long term incentive plan which was approved by the Company's stockholders in May 2005 and in May 2015. Employees have been awarded non-vested stock units with performance conditions, non-vested stock units with market conditions and non-vested restricted stock. The restrictions on the non-vested restricted stock awards lapse at the end of a specified service period, which is typically approximately three years from the date of grant. Restrictions could lapse sooner upon a business combination, death, disability or after an employee qualifies for retirement. The non-vested stock units will be converted into a number of shares of Company stock depending on performance and market conditions at the end of a specified service period, lasting approximately three years. The performance condition awards will be converted into a number of shares of Company stock based on the Company's average return on invested capital during the service period. Similarly, the market condition awards will be converted into a number of shares depending on the appreciation of the Company's stock compared to the NASDAQ Transportation Index. Board members were granted time-based awards with vesting periods of approximately six or twelve months. The Company expects to settle all of the stock unit awards by issuing new shares of stock. The table below summarizes award activity.

The average grant-date fair value of each performance condition award, non-vested restricted stock award and time-based award granted by the Company in 2017 was $16.72, the fair value of the Company’s stock on the date of grant. The average grant-date fair value of each market condition award granted in 2017 was $20.18. The market condition awards were valued using a Monte Carlo simulation technique, a risk-free interest rate of 1.7% and a volatility of 34.7% based on volatility over three years using daily stock prices.

For the nine month periods ending September 30, 2017 and 2016, the Company recorded expense of $2.6 million and $2.2 million, respectively, for stock incentive awards. At September 30, 2017, there was $4.7 million of unrecognized expense related to the stock incentive awards that is expected to be recognized over a weighted-average period of 1.3 years. As of September 30, 2017, none of the awards were convertible, 324,599 units of the Board members time-based awards had vested and none of the outstanding shares of the restricted stock had vested. These awards could result in a maximum number of 1,360,474 additional outstanding shares of the Company’s common stock depending on service, performance and market results through December 31, 2019.

Diluted earnings (loss) per share from continuing operations	$	(0.48	)	$	0.04	$	(1.23	)	$	0.34

The determination of diluted earnings per share requires the exclusion of the fair value re-measurement of the stock warrants recorded as a liability (see Note B), if such warrants have an anti-dilutive effect on earnings per share. For periods in which equivalent shares have a dilutive effect on earnings per share, the weighted-average diluted shares outstanding is calculated using the treasury method. Under this method, the number of diluted shares is determined by dividing the assumed proceeds of the warrants recorded as a liability by the average stock price during the period and comparing that amount with the number of corresponding warrants outstanding.

The underlying warrants as of September 30, 2017 and 2016, could have resulted in 14.9 million and 9.8 million additional shares of the Company's common stock, respectively, if the warrants recorded as a liability were settled by tendering cash. The warrants recorded in stockholders' equity as of September 30, 2017 and 2016, could have resulted in 8.1 million and zero additional shares of the Company's common stock, respectively, if the Company's stock price exceeded $41.35 and the warrants were settled in shares.

The Company's Board of Directors has authorized management to repurchase outstanding common stock of the Company from time to time on the open market or in privately negotiated transactions. The authorization does not require the Company to repurchase a specific number of shares and the Company may terminate the repurchase program at any time. Upon the retirement of common stock repurchased, the excess purchase price over the par value for retired shares of common stock is recorded to additional paid-in-capital.

The Company repurchased common stock during the first six months of 2017, including 380,637 shares on June 6, 2017 from an underwriter in conjunction with an underwritten secondary offering by its largest shareholder, Red Mountain Partners, L.P., a fund that is affiliated with Red Mountain Capital Partners, LLC (“Red Mountain”), a related party, for an aggregate purchase price of $8.5 million. The share price of $22.42 was equal to the price per share paid by the underwriter to Red Mountain.

The Company operates in two reportable segments. The CAM segment consists of the Company's aircraft leasing operations and its segment earnings include an allocation of interest expense. The ACMI Services segment consists of the Company's airline operations, including CMI agreements as well as ACMI and charter service agreements that the Company has with other customers. Due to the similarities among the Company's airline operations, the airline operations are aggregated into a single reportable segment, ACMI Services. The Company's other activities, which include mail and parcel handling services, as well as hub management services for the USPS and AFS, the sale of aircraft parts, aircraft maintenance services, aircraft modifications, facility and ground equipment services, the sales of aviation fuel and other services, are not large enough to constitute reportable segments and are combined in “All other” with inter-segment profit eliminations. Inter-segment revenues are valued at arms-length market rates. Cash and cash equivalents are reflected in Assets - All other below.

The following Management’s Discussion and Analysis has been prepared with reference to the historical financial condition and results of operations of Air Transport Services Group, Inc., and its subsidiaries. Air Transport Services Group, Inc. and its subsidiaries may hereinafter individually and collectively be referred to as "the Company", "we", "our" or "us" from time to time. The following discussion and analysis describes the principal factors affecting the results of operations, financial condition, cash flows, liquidity and capital resources. It should be read in conjunction with the accompanying unaudited condensed consolidated financial statements and the related notes prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") contained in this report and our Annual Report on Form 10-K for the year ended December 31, 2016.

The Company leases aircraft, provides air cargo lift and performs aircraft maintenance and other support services primarily to the air cargo transportation and package delivery industries. Through the Company's subsidiaries, we offer a range of complementary services to delivery companies, freight forwarders, e-commerce operators, airlines and government customers. The Company's principal subsidiaries include two independently certificated airlines, ABX Air, Inc. (“ABX”) and Air Transport International, Inc. (“ATI”), and an aircraft leasing company, Cargo Aircraft Management, Inc. (“CAM”). CAM provides competitive aircraft lease rates by converting passenger aircraft into cargo freighters and offering them to customers under long-term leases.

The Company has two reportable segments: CAM, which leases Boeing 767 and Boeing 757 aircraft and aircraft engines, and ACMI Services, which primarily includes the cargo transportation operations of the Company's two airlines. The ACMI Services segment provides airline operations to its customers. Services include a combination of aircraft, crews, maintenance and insurance through "CMI" and "ACMI" agreements and through charter contracts in which aviation fuel is also included. The Company's other business operations, which primarily provide support services to the transportation industry, include aircraft maintenance, aircraft parts sales, ground and material handling equipment maintenance and mail handling services. These operations do not constitute reportable segments due to their size.

The Company has had long-term contracts with DHL Network Operations (USA), Inc. and its affiliates ("DHL") since August 2003. DHL accounted for 25% of the Company's consolidated revenues for the first nine months of 2017, compared with 35% of the Company's consolidated revenues in the corresponding period in 2016. As of September 30, 2017, the Company, through CAM, leased 16 Boeing 767 aircraft to DHL, 12 of which were being operated by the Company's airlines for DHL under a crew, maintenance and insurance agreement and four aircraft which are operated by a DHL-affiliated airline in the Middle East. Additionally, ATI operated four CAM-owned Boeing 757 aircraft under other operating arrangements with DHL.

The Company has been providing freighter aircraft and services for cargo handling and logistical support for Amazon Fulfillment Services, Inc. ("AFS"), a subsidiary of Amazon.com, Inc. ("Amazon") since September 2015. On March 8, 2016, the Company entered into an Air Transportation Services Agreement (the “ATSA”) with AFS pursuant to which CAM agreed to lease 20 Boeing 767 freighter aircraft to AFS, including 12 Boeing 767-200 freighter aircraft for a term of five years and eight Boeing 767-300 freighter aircraft for a term of seven years.

shares as described below. The first tranche of warrants, issued upon execution of the Investment Agreement, granted Amazon the right to purchase approximately 12.81 million ATSG common shares, with the right to purchase 7.69 million common shares vesting upon issuance on March 8, 2016, and the right to purchase the remaining 5.12 million common shares vesting as the Company delivered additional aircraft leased under the ATSA, or as the Company achieved specified revenue targets in connection with the ATSA. The second tranche of warrants grants Amazon a right to purchase approximately 1.59 million ATSG common shares, and will be issued and vest on March 8, 2018. The third tranche of warrants will be issued and vest on September 8, 2020. The third tranche of warrants will grant Amazon the right to purchase such additional number of ATSG common shares as is necessary to bring Amazon’s ownership to 19.9% of the Company’s pre-transaction outstanding common shares measured on a GAAP-diluted basis, adjusted for share issuances and repurchases by the Company following the date of the Investment Agreement and after giving effect to the warrants granted. The exercise price of the warrants will be $9.73 per share, which represents the closing price of ATSG’s common shares on February 9, 2016. Each of the three tranches of warrants will be exercisable in accordance with its terms through March 8, 2021.

The Company’s accounting for the warrants has been determined in accordance with the financial reporting guidance for equity-based payments to non-employees and for financial instruments. The fair value of the warrants issuable to Amazon is recorded as a lease incentive asset and is amortized against revenues over the duration of the aircraft leases. The warrants are accounted for as financial instruments, and accordingly, the fair value of the outstanding warrants are measured and classified in liabilities at the end of each reporting period. The Company's earnings in future periods will be impacted by the number of warrants granted, the fair value re-measurement of warrants at the end of each period, lease incentive amortizations and the related income tax effects. For income tax calculations, the value and timing of related tax deductions will differ from the guidance described above for financial reporting. For additional information about the accounting for the warrants, see Note B to the accompanying unaudited condensed consolidated financial statements.

As of September 30, 2017, ABX and ATI were leasing 19 in-service aircraft internally from CAM for use in ACMI Services. As of September 30, 2017, six of CAM's 29 Boeing 767-200 aircraft shown in the aircraft fleet table above and six of the 18 Boeing 767-300 aircraft were leased to DHL and operated by ABX. Additionally, twelve of CAM's 29 Boeing 767-200 aircraft and eight of CAM's 18 Boeing 767-300 aircraft were leased to AFS and operated by ABX or ATI. CAM leased the other eleven Boeing 767-200 aircraft and four Boeing 767-300 aircraft to external customers, including four Boeing 767-200 aircraft to DHL that are being operated by a DHL-affiliated airline. The carrying values of the total in-service fleet as of September 30, 2017 was $881.6 million compared to $793.9 million as of December 31, 2016. The table above does not reflect one Boeing 767-200 passenger aircraft owned by CAM.

External customer revenues from continuing operations increased by $60.8 million to $254.1 million and increased by $198.0 million to $745.2 million for the three and nine month periods ended September 30, 2017, respectively, compared to the corresponding periods of 2016. Excluding directly reimbursed revenues, customer revenues increased $49.1 million and $146.0 million during the three and nine month periods ended September 30, 2017, respectively, compared to the corresponding periods of 2016. External customer revenues increased due to additional aircraft leases, expanded CMI and logistics services for AFS and aircraft maintenance and modification services for various customers.

The consolidated net losses from continuing operations were $28.2 million and $72.4 million for the three and nine month periods ended September 30, 2017, respectively, compared to earnings of $2.1 million and $21.8 million for the corresponding periods of 2016. The pre-tax losses from continuing operations were $20.8 million and $53.1 million for the three and nine month periods ended September 30, 2017, respectively, compared to pre-tax earnings of $3.1 million and $34.0 million for the corresponding periods of 2016. Earnings were affected by specific events and certain adjustments that do not directly reflect our underlying operations among the years presented. On a pre-tax basis, earnings included net losses of $34.4 million and $100.2 million for the three and nine month periods ended September 30, 2017, respectively, for the re-measurement of financial instruments, including warrant obligations granted to Amazon, to fair value. This compares to pre-tax losses for re-measurements of $8.5 million and $3.4 million for the corresponding periods of 2016. Pre-tax earnings were also reduced by $3.9 million and $9.8 million for the three and nine month periods ended September 30, 2017, respectively, for the amortization of lease incentives given to AFS in the form of warrants, compared to $1.4 million and $2.4 million for the corresponding periods of 2016. Additionally, pre-tax earnings from continuing operations included expenses of $5.5 million and $5.9 million for the three and nine month periods ending September 30, 2017, respectively, for settlement charges and other non-service components of retiree benefit plans, compared to $2.2 million and $6.6 million for the corresponding periods of 2016. Pre-tax earnings for the third quarter of 2017 included a $0.9 million charge for the Company's share of development costs for a new

joint venture. Pre-tax earnings for the first quarter of 2016 also included a $1.2 million charge for the Company's share of capitalized debt issuance costs that were charged off when West Atlantic AB, a non-consolidated affiliate, restructured its debt. After removing the effects of these items, adjusted pre-tax earnings from continuing operations, a non-GAAP measure (a definition and reconciliation of adjusted pre-tax earnings from continuing operations follows) were $24.0 million and $63.7 million for the three and nine months ended September 30, 2017, respectively, compared to $15.2 million and $47.7 million for 2016.

Adjusted pre-tax earnings from continuing operations for the third quarter and first nine months of 2017 improved compared to 2016, driven primarily by additional revenues and the improved financial results of our airline operations. We also experienced additional revenues and earnings due to the acquisition of Pemco World Air Services, Inc. ("Pemco") in December 2016 and the expansion of gateway operations for AFS since June of 2016. This growth in revenue was partially offset by the cost necessary to support expanded flight operations, including training costs related to new flight crews, higher aircraft depreciation expense and more employee expenses, particularly in support of logistical services.

Adjusted pre-tax earnings from continuing operations, a non-GAAP measure, is pre-tax earnings excluding settlement charges and other non-service components of retiree benefit plans, gains and losses for the fair value re-measurement of financial instruments, lease incentive amortizations, the start-up costs of a non-consolidated joint venture and the charge off of debt issuance costs from a non-consolidated affiliate during the first quarter of 2016. We exclude these items from adjusted pre-tax earnings because they are distinctly different in their predictability or not closely related to our on-going operating activities. Management uses adjusted pre-tax earnings to compare the

As of September 30, 2017 and 2016, CAM had 47 and 38 aircraft under lease to external customers, respectively. Revenues from external customers totaled $40.9 million and $104.1 million for the three and nine month periods ending September 30, 2017, respectively, compared to $27.9 million and $86.1 million for the corresponding periods of 2016. CAM's revenues from the Company's airlines totaled $17.5 million and $51.2 million for the three and nine month periods ending September 30, 2017, respectively, compared to $18.4 and $59.4 for the corresponding periods of 2016, reflecting the transition of CAM owned aircraft to long-term leases with external customers. CAM's aircraft leasing and related revenues, which excludes customer lease incentive costs, increased $14.6 million and $17.9 million during the three and nine month periods ended September 30, 2017, respectively, compared to the corresponding periods of 2016, primarily as a result of new aircraft leases since October 1, 2016, additional engine maintenance agreements and the timing of maintenance related revenues. CAM's revenues related to maintenance increased $7.5 million and $2.3 million for the three and nine month periods ended September 30, 2017, respectively, compared to the corresponding periods of 2016. CAM's revenues related to maintenance can vary among periods due to the timing of customer maintenance events.

CAM's pre-tax earnings were reduced by the increased amortization for the value of warrants issued to Amazon as a lease incentive. The amortization of the lease incentive increased by $2.5 million and $7.4 million for the three and nine months ended September 30, 2017 compared to the corresponding periods of 2016 due to additional vesting of warrants and a higher value of warrants at the time of vesting. CAM's pre-tax earnings, inclusive of an interest expense allocation, were $19.4 million and $45.6 million during the three and nine month periods ended September 30, 2017, respectively, compared to $16.1 million and $51.8 million during the corresponding periods of 2016. Increased earnings for the third quarter reflect additional aircraft leases and the timing of customer maintenance revenues and related expenses. Decreased earnings for the first nine months reflect more amortization of the value of warrants issued to Amazon as a lease incentive, higher depreciation expense for eight additional Boeing 767-300 aircraft, the interruption of lease revenues when transitioning aircraft between customers and increased interest allocation due to the higher debt levels.

During the first nine months of 2017, CAM purchased five 767-300 passenger aircraft for freighter conversion. As of September 30, 2017, all five of these Boeing 767-300 passenger aircraft and one other Boeing 767-300 passenger aircraft purchased in 2016 were being modified from passenger to freighter configuration. The Company also purchased two Boeing 737-400 aircraft during the first nine months of 2017, and these aircraft are currently being modified from passenger to freighter configuration.

The ACMI Services segment provides airline operations to its customers, typically under contracts providing for a combination of aircraft, crews, maintenance and insurance ("ACMI"). Our customers are usually responsible for supplying the necessary aviation fuel and cargo handling services and reimbursing our airline for other operating expenses such as landing fees, ramp expenses, certain aircraft maintenance expenses and fuel procured directly by the airline. Aircraft charter agreements, including those for the U.S. Military, usually require the airline to provide full service, including fuel and other operating expenses for a fixed, all-inclusive price. As of September 30, 2017, ACMI Services included 51 aircraft, including 19 leased internally from CAM, 12 CAM-owned freighter aircraft which are under lease to DHL and operated by ABX under a CMI agreement, and 20 CAM-owned freighter aircraft which are under lease to AFS and operated by ATI and ABX under the ATSA.

Total revenues from ACMI Services increased $18.2 million and $78.6 million during the three and nine month periods ended September 30, 2017 to $146.9 million and $436.4 million, respectively, compared to the corresponding periods of 2016. Airline services revenues from external customers, which do not include revenues for the reimbursement of fuel and certain operating expenses, increased $6.5 million and $26.5 million for the three and nine month periods ended September 30, 2017, respectively, compared to the corresponding periods of 2016. Improved revenues were driven by additional aircraft operations for AFS and reflect an 8% and 21% increase in billable block hours for both the three and nine month periods ended September 30, 2017, compared to the corresponding periods of 2016. In the third quarter of 2017, we added two CAM-owned Boeing 767-300 aircraft into ACMI Service for AFS. As of September 30, 2017, ACMI Services were operating seven more aircraft compared to September 30, 2016. Beginning in April 2016, in conjunction with the long-term leases executed between AFS and CAM, the related aircraft rent revenues for five aircraft operated for AFS during the first quarter of 2016 are reflected under CAM instead of ACMI Services.

ACMI Services had pre-tax losses of $5.2 million and $8.8 million during the three and nine month periods ended September 30, 2017, respectively, compared to pre-tax losses of $9.7 million and $27.2 million for the corresponding periods of 2016. Pre-tax results in 2017 compared to 2016 were affected by expanded revenues, the timing of scheduled airframe maintenance events, crew training and related expenses, and increased pension expenses. Scheduled airframe maintenance expense increased $0.9 million and decreased $3.1 million during the three and nine month periods ended September 30, 2017, respectively, compared to the corresponding periods of 2016. Airframe maintenance expense varies depending upon the number of C-checks and the scope of the checks required for those airframes scheduled for maintenance. Pension expense for ACMI Services, including non-service components of retiree benefit costs, increased $3.3 million and decreased $0.8 million as actuarially determined for the three and nine month periods ending September 30, 2017, respectively, compared to the corresponding periods of 2016. The pension expense in the third quarter of 2017 included a $5.3 million pre-tax charge for the settlement of certain retirement obligations through a third party group annuity contract.

Achieving longer term profitability in ACMI Services will depend on a number of factors, including customer flight schedules, revenue levels for airline services, crewmember productivity, the level of pilot pay, employee benefits, aircraft maintenance schedules and the number of aircraft we operate. Currently each of the Company's airlines are negotiating with their respective flight crewmembers' collective bargaining units. These negotiations could result in changes that may effect the productivity and costs of our operations.

We provide related support services to our ACMI Services customers and other airlines by leveraging our knowledge and capabilities developed for our own operations over the years. The Company's aircraft maintenance, engineering and repair businesses, Airborne Maintenance and Engineering Services, Inc. ("AMES") and Pemco, sell aircraft parts and provide aircraft maintenance and modification services. We also provide mail sorting, parcel handling and logistical support to the U.S. Postal Service (“USPS”) at five USPS facilities and similar services to certain AFS hubs and gateway locations in the U.S. We provide other ground services for our own airlines and external customers, including the sale

External customer revenues from all other activities were $66.2 million and $204.7 million for the three and nine month periods ended September 30, 2017, respectively, compared to $36.6 million and $103.3 million for the corresponding periods of 2016. Revenues from our mail sorting, parcel handling and logistical support services increased $24.8 million and $61.0 million during the three and nine month periods ended September 30, 2017, respectively, compared to 2016, reflecting higher contractual costs and additional AFS locations. Additionally, airframe maintenance and modification revenues from external customers increased by $5.0 million and $40.3 million during the three and nine month periods ended September 30, 2017, respectively, primarily due to the addition of Pemco, which was acquired at the end of 2016. Revenues from aircraft maintenance can vary among periods due to the timing of scheduled maintenance events and the completion level of work during a period.

The pre-tax earnings from other activities decreased by $4.4 million and $1.1 million during the three and nine month periods ended September 30, 2017 to $0.7 million and $12.0 million, respectively, compared to the corresponding periods in 2016, principally reflecting the termination of aircraft fueling and hub logistics services we provided for Amazon at the airport in Wilmington, Ohio through May of 2017, as well as the timing of completion of airframe services. Revenues for scheduled airframe maintenance and modification services are recognized by our subsidiaries when the customer work is completed.

Pre-tax results related to former sorting operations were a $6.7 million loss and a $0.2 million gain for the first nine months of 2017 and 2016, respectively. Results in the third quarter of 2017 included a $7.6 million pre-tax charge for the settlement of certain retirement obligations through a third party group annuity contract. The results of discontinued operations primarily reflect the effects of defined benefit pension plans for former employees that supported sort operations under a former hub service agreement with DHL.

Salaries, wages and benefits expense increased $7.3 million and $39.9 million during the three and nine month periods ended September 30, 2017, respectively, compared to the corresponding periods of 2016. The increase in expense for the third quarter of 2017 reflects the $5.3 million settlement charge for the pension plan and $4.7 million for Pemco acquired in December 2016, offset by a reduction in pilot premium pay from year-ago levels and the reduction in the number of employees for the Wilmington, Ohio logistics operation, which was terminated in May 2017. The increase in expense through the first nine months of 2017 also includes higher headcount for expanded flight operations and package handling services during the first half of 2017.

Depreciation and amortization expense increased $3.7 million and $12.2 million during the three and nine month periods ended September 30, 2017, respectively, compared to the corresponding periods of 2016. The increase in depreciation expense reflects incremental depreciation for eight Boeing 767-300 aircraft and additional aircraft engines added to the operating fleet since October, 2016, as well as capitalized heavy maintenance and navigation technology upgrades. We expect depreciation expense to increase during future periods in conjunction with our fleet expansion and capital spending plans.

Maintenance, materials and repairs expense increased by $2.9 million and $10.0 million during the three and nine month periods ended September 30, 2017, respectively, compared to the corresponding periods of 2016. The increase is primarily due to the addition of Pemco's maintenance and materials, which added $7.0 million and $21.1 million of expenses for the three and nine month periods ended September 30, 2017, respectively, compared to the corresponding periods of 2016. The additional expense from Pemco was partially offset by fewer airframe checks for the Company's airlines and lower airframe maintenance costs for third party customers during 2017 compared to 2016. Aircraft maintenance expenses and materials can vary among periods due to the number of scheduled airframe maintenance checks and the scope of the checks that are performed. In May 2017, our airlines entered into maintenance agreements for certain General Electric CF6 engines that power many of the Boeing 767-300 aircraft leased from CAM. Under the agreement, the engines are maintained by the service provider for a fixed fee per cycle. As a result, beginning in June 2017, the airlines began to record engine maintenance expense as flights occur. As a result, we estimate that our airlines' engine maintenance expense will increase approximately $2.0 million per quarter with a partially offsetting reduction to engine depreciation expense.

Fuel expense increased by $9.7 million and $43.0 million during the three and nine month periods ended September 30, 2017, respectively, compared to the corresponding periods of 2016. Fuel expense includes the cost of fuel to operate U.S. Military charters, reimbursable fuel billed to DHL, AFS and other ACMI customers, as well as fuel used to position aircraft for service and for maintenance purposes. The increase in fuel expense was driven by a higher level of customer-reimbursed fuel which increased $11.3 million and $48.7 million for the three and nine month periods ended September 30, 2017, respectively, compared to 2016. Fuel expense for military customers and other purposes declined due to fewer block hours flown for military customers in 2017.

Other operating expenses increased by $3.0 million and $6.2 million during the three and nine month periods ended September 30, 2017, respectively, compared to the corresponding periods of 2016. Other operating expenses include professional fees, employee training and utilities. Other operating expenses increased by $0.4 million and $2.3 million for the three and nine month periods ended September 30, 2017, respectively, for the addition of Pemco, acquired at the end of 2016. Other operating expense also increased to support additional aircraft and customer block hours. Losses from a non-consolidated affiliate airline accounted for under the equity method increased $0.6 million and decreased by $0.7 million for the three and nine month periods ended September 30, 2017, respectively, compared to the corresponding periods of 2016.

Interest expense increased by $1.5 million and $3.4 million during the three and nine month periods ended September 30, 2017, respectively, compared to the corresponding periods of 2016. Interest expense increased due to a higher average debt level and interest rates on the Company's outstanding loans, partially offset by more capitalized interest related to our fleet expansion. Capitalized interest increased $0.1 million and $0.6 million during the three and nine month periods ended September 30, 2017 to $0.4 million and $1.5 million, respectively.

Future interest expense will be impacted by convertible notes issued in September 2017. The convertible notes have a principal value of $258.8 million, bear interest at a rate of 1.125% and mature on October 15, 2024. At the time of issuance, the value of the conversion feature of the convertible notes was recorded as a debt discount and is being amortized along with debt issuance cost to interest expense over the seven year term of the convertible notes. We expect the amortization of the debt discount and issuance costs will be approximately $2 million during the fourth quarter of 2017. We received net proceeds of $234.7 million from the issuance of the convertible notes and related bond hedge and warrant transactions. Interest payments for the convertible notes will be $2.9 million annually and there are no scheduled principal payments until maturity, resulting in a combined cash financing rate of approximately 2.55%.

The Company recorded pre-tax net losses on financial instruments of $34.4 million and $100.2 million for the three and nine month periods ended September 30, 2017, respectively, compared to $8.5 million and $3.4 million during the corresponding period of 2016. The 2017 losses are primarily a result of re-measuring, as of September 30, 2017, the fair value of the stock warrants granted to Amazon. An increase in the fair value of the warrants since previous re-measurement dates of June 30, 2017 and December 31, 2016, corresponded to an increase in the traded price of the

The effective tax rate from continuing operations for the three and nine month periods ended September 30, 2017 was (35.9)% and (36.2)%, respectively. These effective tax rates reflect the non deductible tax treatment of certain warrants vesting for Amazon and certain warrant revaluation losses at the end of the period. The effective tax rates for the three and nine month periods ended September 30, 2017 are negative because the warrant revaluation losses do not generate a corresponding tax benefit for certain warrants. The effective tax rate without including the effects of the warrants was 37.5% and 36.5% for the three and nine months periods ended September 30, 2017, respectively. The effective tax rate from continuing operations, without including the effects of the warrants for the three and nine month periods ended September 30, 2016 were 35.4% and 36.0%, respectively. The effective tax rate, without including the effects of the warrants, increased for 2017 due to a lesser amount of discrete tax benefits related to state income taxes and employee stock incentive awards.

As of December 31, 2016, the Company had operating loss carryforwards for U.S. federal income tax purposes of approximately $40.2 million, which will begin to expire in 2031 if not utilized before then. We expect to utilize the loss carryforwards to offset federal income tax liabilities in the future. As a result, we do not expect to pay federal income taxes until 2019 or later. However, the Company may be required to pay alternative minimum taxes and certain state and local income taxes before then. The Company's taxable income earned from international flights are primarily sourced to the United States under international aviation agreements and treaties. When we operate in countries without such agreements, the Company could incur additional foreign income taxes.

Net cash generated from operating activities totaled $191.3 million and $143.6 million for the first nine months of 2017 and 2016, respectively. Cash flows generated from operating activities increased during the first nine months of 2017, reflecting improved operating results and customer collections. Cash outlays for pension contributions for the first nine months of 2017 were $4.1 million compared to $6.3 million for the corresponding period of 2016.

Capital spending levels were primarily the result of aircraft modification costs and the acquisition of aircraft for freighter modification. Cash payments for capital expenditures were $218.8 million and $182.1 million for the first nine months of 2017 and 2016, respectively. Capital expenditures in 2017 included $159.4 million for the acquisition of five Boeing 767-300 aircraft and two Boeing 737-400 aircraft and freighter modification costs; $36.2 million for required heavy maintenance; and $23.2 million for other equipment, including purchases of aircraft engines and rotables. Our capital expenditures during 2016 included $133.1 million for the acquisition of nine Boeing 767-300 aircraft, freighter modification costs and next generation navigation modifications; $20.5 million for required heavy maintenance; and $28.5 million for other equipment, including purchases of aircraft engines and rotables.

Net cash provided by financing activities was $61.9 million for the first nine months of 2017 compared to $68.0 million in 2016. During the first nine months of 2017, we drew $90.0 million from the revolving credit facility under the Senior Credit Agreement to fund capital spending. We made debt principal payments of $250.1 million during 2017. Our borrowing activities were necessary to acquire and modify aircraft for deployment into air cargo markets.

In September 2017, we received proceeds of $258.8 million from the issuance of convertible notes. In conjunction with the issuance of convertible notes, we received $38.5 million for the issuance of stock warrants and paid $56.1 million for related convertible note hedges. We paid issuance costs of $6.5 million for these transactions. The net proceeds from these transactions were $234.7 million, of which $205.0 million was used to pay down the balance of our revolving credit facility, thereby increasing the amount available for future draws under that facility. The convertible notes bear interest at a rate of 1.125% and mature on October 15, 2024, unless repurchased or converted in accordance

We estimate that capital expenditures for 2017 will total $335 million of which $265 million will be related to aircraft purchases and freighter modifications. Actual capital spending for any future period will be impacted by aircraft acquisitions, maintenance and modification processes. We expect to finance the capital expenditures from current cash balances, future operating cash flow and the Senior Credit Agreement. The Company outsources a significant portion of the aircraft freighter modification process to a non-affiliated third party. The modification primarily consists of the installation of a standard cargo door and loading system. For additional information about the Company's aircraft modification obligations, see Note H of the accompanying financial statements.

The Company has a Senior Credit Agreement with a consortium of banks that includes an unsubordinated term loan of $74.3 million, net of debt issuance costs, and a revolving credit facility from which the Company had drawn $220.0 million, net of repayments, as of September 30, 2017. The revolving credit facility has a capacity of $545.0 million, permitted additional indebtedness of $300.0 million of which $258.8 million has been utilized for the issuance of convertible notes, and an accordion feature whereby the Company can draw up to an additional $100.0 million subject to the lenders' consent. The Senior Credit Agreement is collateralized by the Company's fleet of Boeing 767 and 757 aircraft that are not collateralized under aircraft loans. Under the amended terms of the Senior Credit Agreement, the Company is required to maintain collateral coverage equal to 125% of the outstanding balances of the term loan and the maximum capacity of the revolving credit facility or 150% of the outstanding balance of the term loan and the total funded revolving credit facility, whichever is less. The minimum collateral coverage which must be maintained is 50% of the outstanding balance of the term loan plus the revolving credit facility commitment which was $545.0 million. Each year, through May 6, 2019, the Company may request a one year extension of the final maturity date, subject to the lenders' consent. Absent such future extensions, the maturity date is currently set to expire on May 30, 2022.

Under the Senior Credit Agreement, the Company is subject to covenants and warranties that are usual and customary including, among other things, limitations on certain additional indebtedness, guarantees of indebtedness, as well as a total debt to EBITDA ratio and a fixed charge coverage ratio. The Senior Credit Agreement stipulates events of default including unspecified events that may have a material adverse effect on the Company. If an event of default occurs, the Company may be forced to repay, renegotiate or replace the Senior Credit Agreement.

Additional debt or lower EBITDA may result in higher interest rates. Under the Senior Credit Agreement, interest rates are adjusted quarterly based on the prevailing LIBOR or prime rates and a ratio of the Company's outstanding debt level to EBITDA (earnings before interest, taxes, depreciation and amortization expenses). At the Company's current debt-to-EBITDA ratio, the unsubordinated term loan and the revolving credit facility both bear a variable interest rate of 3.24%.

As part of our ongoing business, we do not participate in transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities (“SPEs”), which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As of September 30, 2017 and 2016, we were not involved in any material unconsolidated SPE transactions.

Certain of our operating leases and agreements contain indemnification obligations to the lessor or one or more other parties that are considered usual and customary (e.g. use, tax and environmental indemnifications), the terms of which range in duration and are often limited. Such indemnification obligations may continue after the expiration of the respective lease or agreement. No amounts have been recognized in our financial statements for the underlying fair value of guarantees and indemnifications.

“Management’s Discussion and Analysis of Financial Condition and Results of Operations,” as well as certain disclosures included elsewhere in this report, are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to select appropriate accounting policies and make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingencies. In certain cases, there are alternative policies or estimation techniques which could be selected. On an ongoing basis, we evaluate our selection of policies and the estimation techniques we use, including those related to revenue recognition, post-retirement liabilities, bad debts, self-insurance reserves, valuation of spare parts inventory, useful lives, salvage values and impairment of property and equipment, income taxes, contingencies and litigation. The Company bases its estimates on historical experience, current conditions and on various other assumptions that are believed to be reasonable under the circumstances. Those factors form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources, as well as for identifying and assessing our accounting treatment with respect to commitments and contingencies. Actual results may differ from these estimates under different assumptions or conditions.

As of September 30, 2017, the Company carried out an evaluation, under the supervision and with the participation of the Company's Chief Executive Officer and Chief Financial Officer of the effectiveness of the design and operation of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")). Based upon the evaluation, the Company's Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports filed or submitted by it under the Exchange Act is recorded, processed, summarized and reported within time periods specified in the Securities and Exchange Commission rules and forms and is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

The Company is a party to legal proceedings, including FAA enforcement actions, in various federal and state jurisdictions from time to time arising out of the operation of the Company's business. The amount of alleged liability, if any, from these proceedings cannot be determined with certainty; however, the Company believes that its ultimate liability, if any, arising from pending legal proceedings, as well as from asserted legal claims and known potential legal claims which are probable of assertion, taking into account established accruals for estimated liabilities, should not be material to our financial condition or results of operations.

The Company faces risks that could adversely affect its condition or results of operations. Many of these risks are disclosed in Item 1A of the Company's 2016 Annual Report on form 10-K, filed with the Securities and Exchange Commission on March 8, 2017. The risk factors presented below update, and should be considered in addition to, the risk factors previously disclosed in Item 1A of the Company's 2016 Annual Report on Form 10-K. Other risks that are currently unknown to management or are currently considered immaterial or unlikely, could also adversely affect the Company.

On August 3, 2017 we entered into a joint-venture agreement with Precision Aircraft Solutions, LLC, to develop a passenger-to-freighter conversion program for Airbus A321-200 aircraft. We anticipate approval of a supplemental type certificate by the FAA in 2019. We expect to make contributions equal to our 49% ownership percentage of the program's total costs over the next two years and account for the investment in the joint venture under the equity method of accounting. While the joint venture is developing the conversion program, the Company's results will reflect non operating losses for our 49% share of the joint venture's development costs. The development costs may be larger than we expect and approval may take longer than anticipated. The benefits of our investment may be less than projected.

The convertible note hedge transactions and the warrant transactions that we entered into in September 2017 may affect the value of our common stock. In connection with the pricing of our 1.125% senior convertible notes due 2024 (the "Notes") and the exercise by the initial purchasers of their option to purchase additional Notes, we entered into privately-negotiated convertible note hedge transactions with the hedge counterparties. The convertible note hedge transactions cover, subject to customary anti-dilution adjustments, the number of shares of common stock that initially underlie the Notes. We also entered into separate, privately-negotiated warrant transactions with the hedge counterparties relating to the same number of shares of our common stock that initially underlie the Notes, subject to customary anti-dilution adjustments.

The hedge counterparties and/or their affiliates may modify their hedge positions with respect to the convertible note hedge transactions and the warrant transactions from time to time after the pricing of the Notes. They may do so by purchasing and/or selling shares of our common stock and/or other securities of ours, including the Notes in privately-negotiated transactions and/or open-market transactions or by entering into and/or unwinding various over-the-counter derivative transactions with respect to our common stock. The hedge counterparties are likely to modify their hedge positions during any observation period for the Notes.

The effect, if any, of these activities on the market price of our common stock will depend on a variety of factors, including market conditions, and cannot be determined at this time. Any of these activities could, however, adversely affect the market price of our common stock. In addition, the hedge counterparties and/or their affiliates may choose to engage in, or to discontinue engaging in, any of these transactions with or without notice at any time, and their decisions will be at their sole discretion and not within our control.

We are subject to counterparty risk with respect to the convertible note hedge transactions. The hedge counterparties are financial institutions, and we will be subject to the risk that they might default under the convertible note hedge transactions. Our exposure to the credit risk of the hedge counterparties is unsecured by any collateral. Global economic conditions have from time to time resulted in failure or financial difficulties for many financial institutions. If a hedge counterparty becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at that time under our transactions with that hedge counterparty. Our exposure will depend on many factors but, generally, the increase in our exposure will be correlated to the increase in the market

Conversion of the Notes or exercise of the warrants may dilute the ownership interest of stockholders. Any sales in the public market of the common stock issuable upon such conversion of the Notes or such exercise of the warrants could adversely affect prevailing market prices of our common stock. In addition, the existence of the Notes may encourage short selling by market participants because the conversion of the Notes could depress the price of our common stock.

On August 5, 2014, the Board of Directors authorized the Company to repurchase up to $50.0 million of outstanding common stock. In May 2016, the Board amended the Company's common stock repurchase program increasing the amount that management may repurchase from $50.0 million to $100.0 million of outstanding common stock. The Board's authorization does not require the Company to repurchase a specific number of shares and the Board may terminate the repurchase program at any time. Repurchases may be made from time to time in the open market or in privately negotiated transactions. There is no expiration date for the repurchase program. There were no repurchases made during the third quarter of 2017. As of September 30, 2017, the Company has repurchased 6,435,349 shares and has a maximum dollar value of shares that may yet be purchased under the program of $14.9 million.



-		For the shorter of (a) the Severance Period and (b) 18 months following the covered employee’s termination date, a continuation of eligibility to participate in the Company’s medical, dental, vision and prescription drug plans in which the covered employee was participating (including the covered employee’s spouse and eligible dependents); provided that to receive such coverage, the covered employee must pay the amount that the covered employee would have been required to pay if such covered employee were employed by the Company at such time.

The severance benefits will be discontinued if it is determined that the covered employee has engaged in actions that constitute Cause or has breached the terms of the release, restrictive covenants or any other agreement relating to the covered employee’s employment with the Company or termination thereof. The Severance Period for Tier I Participants is 24 months, for Tier II Participants is 18 months, for Tier III Participants is 12 months, and for Tier IV Participants is six months.

If a covered employee is also a party to a change in control agreement and there occurs a change in control that results in such covered employee being entitled to receive severance benefits thereunder, then the Severance Plan will cease to be applicable to such covered employee, with all payments and benefits to such covered employee arising out of any termination of the employment of such covered employee to be determined and paid in accordance with the terms of such change in control agreement. Similarly, if a covered employee is also a party to an employment agreement with the Company that provides for severance payments and benefits following termination of employment under the same or similar circumstances as are set forth in the Severance Plan, then the Severance Plan will not be applicable to such covered employee so long as such employment agreement is in effect.

As a condition for a covered employee to be eligible to participate in the Severance Plan, and to receive severance benefits under the Severance Plan, a covered employee must agree to comply with the restrictive covenants set forth in the Severance Plan, which restrictive covenants include (a) a confidential information disclosure restriction during the term of the covered employment and thereafter, (b) a non-competition restriction during the term of the covered employee’s employment and for the Restriction Period (as defined below) after such termination of employment and (c) a non-solicitation restriction applicable to the solicitation of actual or prospective customers and employees and contractors of the Company during the term of the covered employee’s employment and for the Restriction Period after such termination of employment. The Restriction Period for Tier I Participants is 24 months, for Tier II Participants is 18 months, for Tier III Participants is 12 months and for Tier IV Participants is six months. The severance benefits will be discontinued if a covered employee breaches any terms of the restrictive covenants.

The Board or the Compensation Committee may amend, suspend or terminate the Severance Plan at any time; provided that (i) no amendment, suspension or termination may materially adversely affect a covered employee’s entitlements under the Severance Plan without the prior written consent of such adversely affected covered employee and (ii) no such amendment, suspension or termination will give the Company the right to recover any amount paid to a covered employee prior to the date of such amendment, suspension or termination or to cause the cessation and termination of payments of severance benefits to any person under the Severance Plan receiving severance benefits.
