In May 2016, we entered into certain agreements with Amazon.com, Inc. and its subsidiary, Amazon Fulfillment Services, Inc., (collectively “Amazon”), which involves, among other things, CMI operation of up to 20 Boeing 767-300 freighter aircraft for Amazon by Atlas, as well as Dry Leasing by Titan. The Dry Leases have a term of ten years from the commencement of each agreement, while the CMI operations are for seven years from the commencement of each agreement (with an option for Amazon to extend the term to ten years). Between August 2016 and November 2018, we placed all 20 767-300 freighter aircraft into service for Amazon. In February 2019, the number of 767-300 freighters in CMI and Dry Lease service for Amazon was reduced to 19 with the

loss of an aircraft. In September 2019, the number of 767-300 freighters in CMI service for Amazon was reduced to 17 with the early termination of CMI services for two aircraft, which remain under dry lease.

In conjunction with the agreements entered into in May 2016, we granted Amazon a warrant providing the right to acquire up to 20% of our outstanding common shares, after giving effect to the issuance of shares pursuant to the warrants, at an exercise price of $37.34 per share, as adjusted (“Warrant A”). As of December 31, 2018, this warrant to purchase 7.5 million shares, as adjusted, had vested in full. Warrant A is exercisable in accordance with its terms through May 2021. As of June 30, 2020, no portion of Warrant A has been exercised.

The agreements entered into in May 2016 also provided incentives for future growth of the relationship as Amazon may increase its business with us. In that regard, we granted Amazon a warrant to acquire up to an additional 10% of our outstanding common shares, after giving effect to the issuance of shares pursuant to the warrants, for an exercise price of $37.34 per share, as adjusted (“Warrant B”). This warrant to purchase 3.77 million shares, as adjusted, will vest in increments of 37,660 shares, as adjusted, each time Amazon has paid $4.2 million of revenue to us, up to a total of $420.0 million, for incremental business beyond the original 20 767-300 freighters. As of June 30, 2020, 225,690 shares, as adjusted, of Warrant B have vested. Upon vesting, Warrant B becomes exercisable in accordance with its terms through May 2023. As of June 30, 2020, no portion of Warrant B has been exercised.

In March 2019, we amended the agreements entered into in 2016 with Amazon, pursuant to which we began providing CMI services using Boeing 737-800 freighter aircraft provided by Amazon. The 737-800 CMI operations are for a term of seven years from the commencement of each agreement (with an option for Amazon to extend the term to ten years). As of June 30, 2020, five 737-800 freighter aircraft entered CMI service. Amazon may, in its sole discretion, place up to 15 additional 737-800 freighter aircraft into service with us by May 31, 2021.

In connection with the amended agreements, we granted Amazon a warrant to acquire up to an additional 9.9% of our outstanding common shares, after giving effect to the issuance of shares pursuant to the warrants, for an exercise price of $52.67 per share, as adjusted (“Warrant C”). When combined with Warrant A and Warrant B, this would allow Amazon to acquire up to a total of 39.9% (after the issuance) of our outstanding common shares and Amazon would be entitled to vote the shares it owns up to 14.9% of our outstanding common shares, in its discretion. Amazon would be required to vote any shares it owns in excess of 14.9% of our outstanding common shares in accordance with the recommendation of our board of directors. After Warrant B has vested in full, this warrant to purchase 6.66 million shares, as adjusted, would vest in increments of 45,623 shares, as adjusted, each time Amazon has paid $6.9 million of revenue to us, up to a total of $1.0 billion, for incremental business beyond Warrant A and Warrant B. As of June 30, 2020, no portion of Warrant C has vested. Upon vesting, Warrant C would become exercisable in accordance with its terms through March 2026.

In May 2020, the warrants issued to the U.S. Treasury (see Note 3 for further discussion) triggered an antidilution adjustment to certain terms of the Amazon warrants as reflected above.

Upon the vesting of Warrant A in previous years, the fair value of the warrant was recognized as a customer incentive asset within Deferred costs and other assets, net and is amortized as a reduction of Operating Revenue in proportion to the amount of revenue recognized over the terms of the Dry Leases and CMI agreements. Determining the amount of amortization related to the CMI agreements requires significant judgment to estimate the total number of Block Hours expected over the terms of those agreements. The fair value of Warrant A was also initially recorded as a warrant liability within Financial instruments and other liabilities (the “Amazon Warrant”). The Amazon Warrant liability is marked-to-market at the end of each reporting period with changes in fair value recorded in Unrealized (gain) loss on financial instruments.

As described in Note 2, we adopted the new accounting guidance for share-based payment awards issued to a customer as of January 1, 2020. Under the amended guidance, approximately 60% of the Amazon Warrant liability related to the CMI agreements as of January 1, 2020 was reclassified to Additional paid-in-capital and will no longer be marked-to-market at the end of each reporting period. The amended guidance does not impact the accounting for the remaining portion of the Amazon Warrant liability related to Dry Lease contracts. We recognized net unrealized losses of $30.7 million and $29.7 million on the Amazon Warrant liability during the three and six months ended June 30, 2020, respectively. We recognized a net unrealized gain of $42.3 million and a net unrealized loss of $4.3 million on the Amazon Warrant during the three and six months ended June 30, 2019, respectively. The fair value of the Amazon Warrant liability was $39.5 million as of June 30, 2020 and $24.3 million as of December 31, 2019.

When it becomes probable that an increment of either Warrant B or C will vest and the related revenue begins to be recognized, the grant date fair value of such portion is recognized as a customer incentive asset within Deferred costs and other assets, net and is amortized as a reduction of Operating Revenue in proportion to the amount of related revenue recognized. The grant date fair value of such increment is also recorded as Additional paid-in-capital. At the time of vesting, any amounts recorded in Additional paid-in-capital related to Dry Lease contracts would be reclassified to the Amazon Warrant liability.

We amortized $9.5 million and $6.9 million of the customer incentive asset as a reduction of Operating Revenue for the three months ended June 30, 2020 and 2019, respectively. We amortized $18.6 million and $13.2 million of the customer incentive asset for the six months ended June 30, 2020 and 2019, respectively

Customer incentive asset included within Deferred costs and other assets is as follows:

Balance at December 31, 2019	$	152,534
Initial value for estimate of vested or expected to vest warrants		5,186
Amortization of customer incentive asset		(18,556	)
Balance at June 30, 2020	$	139,164
