Overview

AAWW is a holding company with two wholly owned operating subsidiaries, Atlas Air, Inc. (“Atlas”) and, as of April 7, 2016, Southern Air, Inc. (“Southern Air”). It also has a 51% economic interest and 75% voting interest in Polar Air Cargo Worldwide, Inc. (“Polar”). In addition, AAWW is the parent company of several wholly owned subsidiaries related to our dry leasing services (collectively referred to as “Titan”). When used in this Report, the terms “we,” “us,” “our,” and the “Company” refer to AAWW and all entities in our consolidated financial statements.

We are a leading global provider of outsourced aircraft and aviation operating services. We operate the world’s largest fleet of 747 freighters and provide customers a broad array of 747, 777, 767, 757 and 737 aircraft for domestic, regional and international cargo and passenger applications. We provide unique value to our customers by giving them access to highly reliable new production freighters that deliver the lowest unit cost in the marketplace combined with outsourced aircraft operating services that we believe lead the industry in terms of quality and global scale. Our customers include express delivery providers, e-commerce retailers, airlines, freight forwarders, the U.S. military and charter brokers. We provide global services with operations in Africa, Asia, Australia, Europe, the Middle East, North America and South America.

Our primary service offerings include the following:

• ACMI, whereby we provide outsourced cargo and passenger aircraft operating solutions, including the provision of an aircraft, crew, maintenance and insurance, while customers assume fuel, demand and price risk. In addition, customers are responsible for landing, navigation and most other operational fees and costs;

• CMI, which is part of our ACMI business segment, whereby we provide outsourced cargo and passenger aircraft operating solutions, including the provision of crew, Line Maintenance and insurance, but not the aircraft. Customers assume fuel, demand and price risk, and are responsible for providing the aircraft (which they may lease from us) and for Heavy and Non-Heavy Maintenance, landing, navigation and most other operational fees and costs;

• Charter, whereby we provide cargo and passenger aircraft charter services to customers, including the U.S. Military Air Mobility Command (“AMC”), brokers, freight forwarders, direct shippers, airlines, sports teams and fans, and private charter customers. The customer pays a fixed charter fee that includes fuel, insurance, landing fees, navigation fees and most other operational fees and costs; and

• Dry Leasing, whereby we provide cargo and passenger aircraft and engine leasing solutions. The customer operates, and is responsible for insuring and maintaining, the flight equipment.

2

We believe that the scale, scope and quality of our outsourced services are unparalleled in our industry. The relative operating cost efficiency of our current 747-8F, 747-400F and 777-200LRF aircraft, including their superior fuel efficiency, range, capacity and loading capabilities, creates a compelling value proposition for our customers and positions us well in the markets we operate. Our growing fleet of 767-300 and 737-400 freighter aircraft are well-suited for regional and domestic applications.

We are focused on the further enhancement of our market-leading ACMI and CMI services. We are currently the only operator offering 747-8F and 777 aircraft under ACMI and CMI agreements, and we have the flexibility to expand our fleet in response to market conditions. We believe that our current fleet, which also includes our 747-400F aircraft, represents one of the most efficient, reliable freighter fleets in the market. Our primary placement for the 747-8F and 747-400F aircraft will continue to be long-term ACMI outsourcing contracts with high-credit-quality customers.

During 2016, we significantly expanded our CMI and Dry Leasing services. In April 2016, the acquisition of Southern Air provided us with immediate entry into the 777 and 737 aircraft operating platforms, with ten aircraft and the potential for developing additional business with existing and new customers. In May 2016, we entered into agreements with Amazon.com, Inc. and its subsidiary, Amazon Fulfillment Services, Inc., (collectively “Amazon”), which involve, among other things, the leasing and operation of 20 Boeing 767-300 freighter aircraft. The first two aircraft were placed in service in August 2016 and February 2017, and the remainder are expected to be placed in service by the end of 2018. In addition to the contracts above, our Dry Leasing business includes six 777 freighters that are Dry Leased to customers on a long-term basis. Our Dry Leasing portfolio diversifies our business mix and enhances our predictable, long-term revenue and earnings streams.

AAWW was incorporated in Delaware in 2000. Our principal executive offices are located at 2000 Westchester Avenue, Purchase, New York 10577, and our telephone number is (914) 701-8000.

Operations

Introduction.  Our business is organized into three operating segments based on our service offerings: ACMI, Charter and Dry Leasing. All segments are directly or indirectly engaged in the business of air transportation services but have different commercial and economic characteristics. Each operating segment is separately reviewed by our chief operating decision maker to assess operating results and make resource allocation decisions. Additional information regarding our reportable segments can be found in Note 13 to our consolidated financial statements included in Item 8 of Part II of this Report (the “Financial Statements”).

ACMI.  The core of our business is generally providing cargo aircraft outsourcing services to customers on an ACMI and CMI basis, in exchange for guaranteed minimum revenues at predetermined levels of operation for defined periods of time. ACMI and CMI contracts provide a predictable annual revenue and cost base by minimizing the risk of fluctuations such as price, fuel and demand risk in the air cargo business. Our revenues and most of our costs under ACMI and CMI contracts are denominated in U.S. dollars, minimizing currency risks associated with international business.

All of our ACMI and CMI contracts provide that the aircraft remain under our exclusive operating control, possession and direction at all times. These contracts further provide that both the contracts and the routes to be operated may be subject to prior and periodic approvals of the U.S. or foreign governments. Revenue from ACMI and CMI contracts is typically recognized as the Block Hours are operated on behalf of a customer during a given month, as defined contractually. If a customer flies below a minimum contracted Block Hour guarantee, the contracted minimum revenue amounts are recognized as revenue. The original length of these contracts generally ranges from two to seven years, although we do offer contracts of shorter or longer duration. In addition, we have also operated short-term ACMI cargo and passenger services and we expect to continue to provide such services.

As a percentage of our operating revenue, ACMI segment revenue represented 45.4% in 2016, 43.4% in 2015 and 43.2% in 2014. As a percentage of our operated Block Hours, ACMI represented 72.2% in 2016, 70.9% in 2015 and 71.4% in 2014.

Charter.  Our Charter business primarily provides full planeload cargo and passenger aircraft to customers, including the AMC, brokers, freight forwarders, direct shippers, airlines, sports teams and fans, and private charter customers. Charters are for one or more flights based on a specific origin and destination. Atlas also provides limited airport-to-airport cargo services to select markets, including several cities in South America. In addition, we occasionally earn revenue on subcontracted Charter flights. Atlas typically bears all direct operating costs for both cargo and passenger charters, which include fuel, insurance, landing and navigation fees, and most other operational fees and costs.

As a percentage of our operating revenue, Charter segment revenue, which includes fuel and other operational costs, represented 47.9% in 2016, 49.9% in 2015 and 50.4% in 2014. As a percentage of our operated Block Hours, Charter represented 27.0% in 2016, 28.2% in 2015 and 27.7% in 2014.

Dry Leasing.  Our Dry Leasing business provides aircraft and engines to customers, including some CMI customers, for compensation that is typically based on a fixed monthly amount (a “Dry Lease”). This business is primarily operated by Titan, which is principally a cargo aircraft dry lessor, but also owns and manages aviation assets such as passenger narrow-body aircraft, engines and related equipment. Titan also markets its expertise in asset management, passenger-to-freighter conversion and other aviation-related technical services. As a percentage of our operating revenue, Dry Leasing segment revenue represented 5.8% in 2016, 5.9% in 2015 and 5.6% in 2014.

Other Revenue.  As a percentage of our operating revenue, Other revenue, which includes administrative and management support services and flight simulator training, represented 0.9% in 2016, 0.8% in 2015 and 0.8% in 2014.

DHL Investment and Polar

DHL Network Operations (USA), Inc. (“DHL”) holds a 49% equity interest and a 25% voting interest in Polar (see Note 3 to our Financial Statements). AAWW owns the remaining 51% equity interest and 75% voting interest. Under a 20-year blocked space agreement that expires in 2027 (the “BSA”), Polar provides air cargo capacity to DHL. Atlas and Polar also have a flight services agreement, whereby Atlas is compensated by Polar on a per Block Hour basis, subject to a monthly minimum Block Hour guarantee, at a predetermined rate with the opportunity for performance premiums that escalate annually. Under the flight services agreement, Atlas provides Polar with crew, maintenance and insurance for the aircraft. Under separate agreements, Atlas and Polar supply administrative, sales and ground support services to one another. Deutsche Post AG (“DP”) has guaranteed DHL’s (and Polar’s) obligations under the various agreements described above. AAWW has agreed to indemnify DHL for and against various obligations of Polar and its affiliates. Collectively, these agreements are referred to in this Report as the “DHL Agreements”. The DHL Agreements provide us with a minimum guaranteed annual revenue stream from aircraft that have been dedicated to Polar for DHL and other customers’ freight over the life of the agreements. DHL provides financial support and also assumes the risks and rewards of the operations of Polar.

4

Combined with Polar, we provide ACMI, CMI, Charter and Dry Leasing services to support DHL’s transpacific express, North American and intra-Asian networks. In addition, we fly between the Asia Pacific region, the Middle East and Europe on behalf of DHL and other customers. Atlas also provides incremental charter capacity to Polar and DHL on an ad hoc basis. The following table summarizes the aircraft types and services provided to DHL as of December 31, 2016:

Aircraft Type	Service		Total
747-8F		ACMI		6
747-400F		ACMI		7

Total				37

Amazon

In May 2016, we entered into certain agreements with Amazon, which involve, among other things, CMI operation of 20 Boeing 767-300 freighter aircraft for Amazon by Atlas, as well as Dry Leasing by Titan. The Dry Leases will have a term of ten years, while the CMI operations will be for seven years (with an option for Amazon to extend the term to ten years). The first two aircraft were placed in service in August 2016 and February 2017, and the remainder are expected to be placed in service by the end of 2018.

In conjunction with these agreements, 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 $37.50 per share. A portion of the warrant, representing the right to purchase 3.75 million shares, vested immediately upon issuance of the warrant and the remainder of the warrant, representing the right to purchase 3.75 million shares, will vest in increments of 375,000 as the lease and operation of each of the 11^th through 20^th aircraft commences. The warrant will be exercisable in accordance with its terms through 2021. As of December 31, 2016, no warrants have been exercised.

The agreements also provide 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 $37.50 per share. This warrant to purchase 3.75 million shares will vest in conjunction with payments by Amazon for additional business with us. The warrant will be exercisable in accordance with its terms through 2023.

Sales and Marketing

We have regional sales offices in various locations around the world that cover the Americas, Asia Pacific, Europe, Africa and Middle East regions. These offices market our ACMI, CMI and Dry Leasing services to express delivery providers, e-commerce retailers, airlines and freight forwarders. They also market our cargo and passenger Charter services to charter brokers, the U.S. military, freight forwarders, direct shippers and airlines.

Fuel

Historically, aircraft fuel is one of the most significant expenses for us. During 2016, 2015 and 2014, fuel costs represented 16.5%, 19.6%, and 24.9%, respectively, of our total operating expenses. Fuel prices and

5

availability are subject to wide price fluctuations based on geopolitical issues, supply and demand, which we can neither control nor accurately predict. The following table summarizes our total fuel consumption and costs:

	2016		2015		2014
Gallons consumed (in thousands)		163,862		147,081		131,787
Average price per gallon, including tax	$	1.68	$	2.27	$	3.07
Cost (in thousands)	$	275,113	$	333,390	$	404,263

Our exposure to fluctuations in fuel price is limited to the commercial portion of our Charter business only. The ACMI segment has no direct fuel price exposure because ACMI and CMI contracts require our customers to pay for aircraft fuel. Similarly, we generally have no fuel price risk for AMC charters because the price is set under our contract with the AMC, and we receive or make payments to adjust for price increases and decreases from the contractual rate.

In the past, we have not experienced significant difficulties with respect to fuel availability. Although we do not currently anticipate a significant reduction in the availability of aircraft fuel, a number of factors, such as geopolitical uncertainties in oil-producing nations and shortages of and disruptions to refining capacity or transportation of aircraft fuel from refining facilities, make accurate predictions unreliable. For example, hostilities and political turmoil in oil-producing nations could lead to disruptions in oil production and/or to substantially increased oil prices. Any inability to obtain aircraft fuel at competitive prices would materially and adversely affect our results of operation and financial condition.

Employees

Our business depends on highly qualified management, operations and flight personnel. As a percentage of our consolidated operating expenses, salaries, wages and benefits accounted for approximately 25.4% in 2016, 20.7% in 2015 and 19.2% in 2014. As of December 31, 2016, we had 2,646 employees, 1,581 of whom were pilots. We maintain a comprehensive training program for our pilots in compliance with U.S. Federal Aviation Administration (“FAA”) requirements, in which each pilot regularly attends recurrent training programs.

Pilots of Atlas and Southern Air, and flight dispatchers of Atlas and Polar are represented by the International Brotherhood of Teamsters (the “IBT”). These employees represented approximately 60.5% of our workforce as of December 31, 2016. We have a five-year collective bargaining agreement (“CBA”) with our Atlas pilots, which became amendable in September 2016; and a four-year CBA with the Southern Air pilots, which became amendable in November 2016. We also have a five-year CBA with our Atlas and Polar dispatchers, which becomes amendable in November 2017.

After we completed the acquisition of Southern Air in April 2016, we informed the IBT of our intention to pursue (and we have been pursuing) a complete operational merger of Atlas and Southern Air. Pursuant to the merger provisions in both the Atlas and Southern Air CBAs, joint negotiations for a single CBA for Atlas and Southern Air should commence promptly. Once a seniority list is presented to us by the unions, it triggers an agreed-upon time frame to negotiate a new joint CBA with any unresolved issues submitted to binding arbitration. After the merger process began, the IBT filed an application for mediation with the National Mediation Board (“NMB”) on behalf of the Atlas pilots. We have opposed the mediation application as it is not in accordance with the merger provisions in the parties’ existing CBAs, which have a defined and streamlined process for negotiating a joint CBA when a merger occurs, as in the case with the Atlas and Southern Air merger. The NMB conducted a pre-mediation investigation in June 2016, which is currently pending. Due to a lack of meaningful progress in such discussions, in February 2017, we filed a lawsuit against the IBT to compel arbitration on the issue of whether the merger provisions in Atlas and Southern Air’s CBAs apply to the bargaining process.

We are subject to risks of work interruption or stoppage as permitted by the Railway Labor Act of 1926 (the “Railway Labor Act”) and incur additional administrative expenses associated with union representation of our employees.

Maintenance

Maintenance represented our third-largest operating expense for the year ended December 31, 2016. Primary maintenance activities include scheduled and unscheduled work on airframes and engines. Scheduled maintenance activities encompass those activities specified in our maintenance program approved by the FAA. The costs necessary to adhere to these maintenance programs may increase over time, based on the age of the equipment or due to FAA airworthiness directives (“ADs”).

Under the ADs issued pursuant to the FAA’s Aging Aircraft Program, we are subject to extensive aircraft examinations and may be required to undertake structural modifications to our fleet from time to time to address any problems of corrosion and structural fatigue. The FAA has issued increased inspection and maintenance requirements depending on aircraft type and ADs requiring certain additional aircraft modifications. We believe all aircraft in our fleet are in compliance with all existing ADs. It is possible, however, that additional ADs applicable to the types of aircraft or engines included in our fleet could be issued in the future and that the cost of complying with such ADs could be substantial.

Under our FAA-approved maintenance programs, all Heavy Maintenance is currently performed by third-party service providers that are compensated on a time-and-material basis as we believe they provide the most reliable and efficient means of maintaining our aircraft fleet.

Insurance

We maintain insurance of the types and in amounts deemed adequate and consistent with current industry standards. Principal coverage includes: liability for injury to members of the public, including passengers; injury to crewmembers and ground staff; damage to our property and that of others; and loss of, or damage to, flight equipment, whether on the ground or in flight.

Aviation insurance premiums historically have fluctuated based on factors that include the loss history of the industry in general and the insured carrier in particular. Terrorist attacks and other adverse events involving aircraft could result in increases in insurance costs and could affect the price and availability of such coverage. We participate in an insurance pooling arrangement with DHL and its partners. This allows us to obtain aviation hull and liability, war-risk hull and cargo loss, crew, third-party liability insurance and hull deductible coverage at reduced rates from the commercial insurance providers. If we are no longer included in this arrangement for any reason or if pool members have coverage incidents, we may incur higher insurance costs.

Governmental Regulation

General.  Atlas, Polar and Southern Air (the “Airlines”) are subject to regulation by the U.S. Department of Transportation (the “DOT”) and the FAA, among other U.S. and foreign government agencies. The DOT primarily regulates economic issues affecting air service, such as certification, fitness and citizenship, competitive practices, insurance and consumer protection. The DOT has the authority to investigate and institute proceedings to enforce its economic regulations and may assess civil penalties, revoke operating authority or seek criminal sanctions. The Airlines hold DOT-issued certificates of public convenience and necessity plus exemption authority to engage in scheduled air transportation of property and mail in domestic, as well as enumerated international markets, and charter air transportation of property and mail on a worldwide basis. Atlas additionally holds worldwide passenger charter authority.

The DOT conducts periodic evaluations of each air carrier’s fitness and citizenship. In the area of fitness, the DOT seeks to ensure that a carrier has the managerial competence, compliance disposition and financial resources needed to conduct the operations for which it has been certificated. Additionally, each U.S. air carrier must remain a U.S. citizen by (i) being organized under the laws of the United States or a state, territory or possession thereof; (ii) requiring its president and at least two-thirds of its directors and other managing officers

7

to be U.S. citizens; (iii) allowing no more than 25% of its voting stock to be owned or controlled, directly or indirectly, by foreign nationals; and (iv) not being otherwise subject to foreign control. The DOT broadly interprets “control” to exist when an individual or entity has the potential to exert substantial influence over airline decisions through affirmative action or the threatened withholding of consents and/or approvals. We believe the DOT will continue to find the Airlines’ fitness and citizenship favorable.

In addition, the Airlines are required to hold valid FAA-issued air carrier certificates and FAA-approved operations specifications authorizing operation in specific regions with specified equipment under specific conditions and are subject to extensive FAA regulation and oversight. The FAA is the U.S. government agency primarily responsible for regulation of flight operations and, in particular, matters affecting air safety, such as airworthiness requirements for aircraft, operating procedures, mandatory equipment and the licensing of pilots, mechanics and dispatchers. The FAA monitors compliance with maintenance, flight operations and safety regulations and performs frequent spot inspections of aircraft, employees and records. The FAA also has the authority to issue ADs and maintenance directives and other mandatory orders relating to, among other things, inspection of aircraft and engines, fire retardant and smoke detection devices, increased security precautions, collision and windshear avoidance systems, noise abatement and the mandatory removal and replacement of aircraft parts that have failed or may fail in the future. In addition, the FAA mandates certain record-keeping procedures. The FAA has the authority to modify, temporarily suspend or permanently revoke an air carrier’s authority to provide air transportation or that of its licensed personnel, after providing notice and a hearing, for failure to comply with FAA rules, regulations and directives. The FAA is empowered to assess civil penalties for such failures or institute proceedings for the imposition and collection of monetary fines for the violation of certain FAA regulations and directives. The FAA is also empowered to modify, suspend or revoke an air carrier’s authority on an emergency basis, without providing notice and a hearing, where significant safety issues are involved.

In December 2011, the FAA adopted a rule to impose new flight and duty time requirements with the stated goal of reducing pilot fatigue. The rule took effect on January 14, 2014. The rule applies to Atlas’ passenger operations but not to the Airlines’ all-cargo operations. The Independent Pilots Association, representing the pilots of United Parcel Service, Inc. (“UPS”), filed a judicial appeal in the U.S. Court of Appeals for the District of Columbia Circuit challenging the FAA decision not to include all-cargo operations in the rule. On March 24, 2016, the Court issued an order denying the appeal. Should the FAA decide either on its own initiative or pursuant to Congressional directive to change the final rule to include all-cargo operations, it could result in a material increase in crew costs for the Airlines. It could also have a material impact on our business, results of operations and financial condition by limiting crew scheduling flexibility and increasing operating costs, especially with respect to long-range flights.

International.  Air transportation in international markets (the vast majority of markets in which the Airlines operate) is subject to extensive additional regulation. The ability of the Airlines to operate in other countries is governed by aviation agreements between the United States and the respective countries (in the case of Europe, the European Union (the “EU”)) or, in the absence of such an agreement, by principles of reciprocity. Sometimes, aviation agreements restrict the number of Airlines that may operate, their frequency of operation, or the routes over which they may fly. This makes it necessary for the DOT to award route and operating rights to U.S. air carrier applicants through competitive route proceedings. International aviation agreements are periodically subject to renegotiation, and changes in U.S. or foreign governments could result in the alteration or termination of such agreements, diminish the value of existing route authorities or otherwise affect Atlas and Polar’s international operations. Foreign government authorities also impose substantial licensing and business registration requirements and, in some cases, require the advance filing and/or approval of schedules or rates. Moreover, the DOT and foreign government agencies typically regulate alliances and other commercial arrangements between U.S. and foreign air carriers, such as the ACMI and CMI arrangements that Atlas maintains. Approval of these arrangements is not guaranteed and may be conditional. In addition, approval during one time period does not guarantee approval in future periods.

8

A foreign government’s regulation of its own air carriers can also affect our business. For instance, the EU places limits on the ability of EU carriers to use ACMI aircraft operated by airlines of non-EU member states. The regulations have a negative impact on our ACMI business opportunities.

Airport Access.  The ability of the Airlines to operate suitable schedules is dependent on their ability to gain access to airports of their choice at commercially desirable times and on acceptable terms. In some cases, this is constrained by the need for the assignment of takeoff and landing “slots” or comparable operational rights. Like other air carriers, the Airlines are subject to such constraints at slot-restricted airports in cities such as Chicago and a variety of foreign locations (e.g., Tokyo, Shanghai and Incheon). The availability of slots is not assured and the inability of the Airlines’ or their ACMI carrier customers to obtain additional slots could inhibit efforts to provide expanded services in certain international markets. In addition, nighttime flight restrictions have been imposed or proposed by various airports in Europe, Canada and the U.S. Depending on their severity, these could have an adverse operational impact.

Access to the New York airspace presents an additional challenge. Because of congestion in the New York area, especially at John F. Kennedy International Airport (“JFK”), the FAA imposes hourly limits on JFK operations of those carriers offering scheduled services and potentially could place limits on Charter flights.

As a further means to address congestion, the FAA allows U.S. airports to raise landing fees to defray the costs of airfield facilities under construction or reconstruction. Any landing fee increases implemented would have an impact on airlines generally.

Security.  The U.S. Transportation Security Administration (“TSA”) extensively regulates aviation security through rules, regulations and security directives that are designed to prevent unauthorized access to passenger and freighter aircraft and the introduction of prohibited items including firearms and explosives onto an aircraft. Atlas and Polar currently operate pursuant to a TSA-approved risk-based security program that, we believe, adequately maintains the security of all aircraft in the fleet. We utilize the TSA, the intelligence community and the private sector as sources for our aggressive threat-based risk-management program. There can be no assurance, however, that we will remain in compliance with existing or any additional security requirements imposed by TSA or by U.S. Congress without incurring substantial costs, which may have a material adverse effect on our operations. To mitigate any such increase, we are working closely with the Department of Homeland Security and other government agencies to ensure that a risk-based management approach is utilized to target specific “at-risk” cargo. This approach will limit any exposure to regulation that would require 100% screening of all cargo at an excessive cost. Additionally, foreign governments and regulatory bodies (such as the European Commission) impose their own aviation security requirements and have increasingly tightened such requirements. This may have an adverse impact on our operations, especially to the extent the new requirements may necessitate redundant or costly measures or be in conflict with TSA requirements. We have successfully implemented all European Commission security programs allowing us unimpeded access to European markets.

Environmental.  We are subject to various federal, state and local laws relating to the protection of the environment, including the discharge or disposal of materials and chemicals and the regulation of aircraft noise, which are administered by numerous state, local and federal agencies. For instance, the DOT and the FAA have authority under the Aviation Safety and Noise Abatement Act of 1979 and under the Airport Noise and Capacity Act of 1990 to monitor and regulate aircraft engine noise. We believe that all aircraft in our fleet materially comply with current DOT, FAA and international noise standards.

We are also subject to the regulations of the U.S. Environmental Protection Agency (the “EPA”) regarding air quality in the United States. All of our aircraft meet or exceed applicable EPA fuel venting requirements and smoke emissions standards.

There is significant U.S. and international government interest in implementing measures to respond to the problem of climate change and greenhouse gas emissions. Various governments, including the United States, are pursuing measures to regulate climate change and greenhouse gas emissions.

9

In October 2013, the International Civil Aviation Organization (“ICAO”) reached a nonbinding agreement to address climate change by developing global market-based measures to assist in achieving a carbon-neutral growth from 2020 onward. In October 2016, ICAO approved a resolution to adopt a global market-based measure known as the Carbon Offsetting and Reduction Scheme for International Aviation (“CORSIA”), which is designed to offset any annual increases in total carbon emissions from international civil aviation above a baseline level determined by the average of 2019 and 2020 emissions. Although various details regarding the implementation of CORSIA still need to be finalized, a pilot phase will run from 2021 to 2023 and, starting in 2019, the airlines of participating countries will begin monitoring and reporting fuel burn during international flights. As a result, for each year starting in 2021, covered airlines may need to purchase allowances to offset their assigned share of emissions overages.

Additionally, the EU continues to pursue a parallel track to address climate change through its Emissions Trading Scheme (“ETS”). Following the end of every year, to the extent the ETS applies, each airline must tender the number of carbon emissions allowances (“Allowances”) corresponding to carbon emissions generated by its covered flight activity during the year. If the airline’s flight activity during the year has produced carbon emissions exceeding the number of Allowances that it has been awarded, the airline must acquire Allowances from other airlines in the open market. In recognition of ICAO’s recent adoption of CORSIA, the ETS was suspended with respect to international aviation through December 31, 2016; however, measures continue to remain applicable to intra-EU aviation. Although certain EU political leaders have stated that the EU is likely to extend the suspension applicable to flights to and from the EU beyond December 31, 2016, we cannot be certain whether or for how long the EU will do so.

In the United States, various constituencies have continued to advocate for controls on greenhouse gas emissions. Previously, both houses of the U.S. Congress passed legislation to impose a carbon-related tax on fuel sold to airlines and other entities. However, a bill has not been signed into law. Also, on August 15, 2016, the U.S. Environmental Protection Agency (“EPA”) issued a final rule finding that greenhouse gas emissions from aircraft cause or contribute to air pollution that may reasonably be anticipated to endanger public health and welfare. That finding could lead to EPA regulation of greenhouse gas emissions from aircraft.

Other Regulations.  Air carriers are also subject to certain provisions of the Communications Act of 1934 because of their extensive use of radio and other communication facilities and are required to obtain an aeronautical radio license from the Federal Communications Commission. Additionally, we are subject to U.S. and foreign antitrust requirements and international trade restrictions imposed by U.S. presidential determination and U.S. government agency regulation, including the Office of Foreign Assets Control of the U.S. Department of the Treasury. We endeavor to comply with such requirements at all times. We are also subject to state and local laws and regulations at locations where we operate and at airports that we serve. Our operations may become subject to additional international, U.S. federal, state and local requirements in the future.

We believe that we are in material compliance with all currently applicable laws and regulations.

Civil Reserve Air Fleet.  As part of our Charter business, Atlas and Polar both participate in the U.S. Civil Reserve Air Fleet (“CRAF”) Program, which permits the U.S. Department of Defense to utilize participants’ aircraft during national emergencies when the need for military airlift exceeds the capability of military aircraft. Participation in the CRAF Program could adversely restrict our commercial business in times of national emergency. Under the CRAF Program, contracts with the AMC typically cover a one-year period. We have made a substantial number of our aircraft available for use by the U.S. military in support of their operations and we operate such flights pursuant to cost-based contracts. Atlas bears all direct operating costs for both passenger and cargo aircraft, which include fuel, insurance, overfly, landing and ground handling expenses. The contracted charter rates (per mile) and fuel prices (per gallon) are fixed by the AMC periodically. We receive reimbursements from the AMC each month if the price of fuel paid by us to vendors for the AMC Charter flights exceeds the fixed price. If the price of fuel paid by us is less than the fixed price, then we pay the difference to the AMC.

10

Airlines may participate in the CRAF Program either alone or through a teaming arrangement. We are a member of the team led by FedEx Corporation (“FedEx”). We pay a commission to the FedEx team, based on the revenues we receive under our AMC contracts. The AMC buys cargo capacity on two bases: a fixed basis, which is awarded both annually and quarterly, and expansion flying, which is awarded on an as-needed basis throughout the contract term. While the fixed business is predictable, Block Hour levels for expansion flying are difficult to predict and thus are subject to fluctuation.

Future Regulation.  The U.S. Congress, the DOT, the FAA, the TSA and other government agencies are currently considering, and in the future may consider, adopting new laws, regulations and policies regarding a wide variety of matters that could affect, directly or indirectly, our operations, ownership and profitability. It is impossible to predict what other matters might be considered in the future and to judge what impact, if any, the implementation of any future proposals or changes might have on our businesses.

Competition

The market for ACMI and CMI services is competitive. We believe that the most important basis for competition in this market is the efficiency and cost-effectiveness of the aircraft assets and the scale, scope and quality of the outsourced operating services provided. Atlas is currently the only provider of ACMI and CMI services with the modern 747-8F and 777 aircraft. The primary ACMI and CMI providers for 747-400 and 767 aircraft include the following: Atlas; Air Atlanta Icelandic; Air Transport Services Group, Inc.; Kalitta Air, LLC; and Western Global Airlines.

The Charter market is competitive, with a number of cargo operators that include AirBridge Cargo Airlines; Cargolux; Kalitta Air, LLC; National Air Cargo; and passenger airlines providing similar services utilizing 747-8Fs, 747-400s and 747-200s. We believe that we offer a superior long-haul aircraft in the 747-8F and 747-400, and we will continue to develop new opportunities in the Charter market for aircraft not otherwise deployed in our ACMI business.

The Dry Leasing business is also competitive. We believe that we have an advantage over other cargo aircraft lessors in this business as a result of our relationships in the cargo market and our insights and expertise as an operator of aircraft. Titan also competes in the passenger aircraft leasing market to develop key customer relationships, enter strategic geographic markets, and/or acquire feedstock aircraft for future freighter conversion. Our primary competitors in the aircraft leasing market include GE Capital Aviation Services; AWAS; Guggenheim Aviation Partners, LLC; Aviation Capital Group Corp.; Aircastle Ltd.; AerCap Holdings N.V.; Air Transport Services Group, Inc.; and Fly Leasing, among many others.

ITEM 1A. RISK FACTORS

You should carefully consider each of the following Risk Factors and all other information in this Report. These Risk Factors are not the only ones facing us. Our operations could also be impaired by additional risks and uncertainties. If any of the following risks and uncertainties develops into actual events, our business, financial condition and results of operations could be materially and adversely affected.

RISKS RELATED TO OUR BUSINESS

Risks Related to Our Business Generally

Deterioration in the airfreight market, global economic conditions or financial markets could adversely affect our business, results of operations, financial condition, liquidity and ability to access capital markets.

Airfreight demand has historically been highly dependent on global economic conditions. If demand for our services, Yields or lease rates deteriorate, it could have a material adverse effect on our business, results of operations and financial condition.

In addition, we may face significant challenges if conditions in the financial markets deteriorate. Our business is capital intensive and growth depends on the availability of capital for new aircraft, among other things. If capital availability deteriorates, we may be unable to raise the capital necessary to finance business growth or other initiatives or to repay our debt when it matures. Our ability to access the capital markets may be restricted at a time when we would like, or need, to do so, which could have an impact on our flexibility to react to changing economic and business conditions.

We could be adversely affected if any of our existing aircraft are underutilized or we fail to redeploy or deploy aircraft with customers at favorable rates. We could also be adversely affected from the loss of one or more of our aircraft for an extended period of time.

Our operating revenues depend on our ability to effectively deploy the aircraft in our fleet and maintain high utilization of our aircraft at favorable rates. If we have underutilized aircraft, we would seek to redeploy those aircraft in our other lines of business or sell them. If we are unable to successfully redeploy our existing aircraft at favorable rates or sell them on favorable terms, it could have a material adverse effect on our business, results of operations and financial condition. In addition, if one or more of our aircraft are out of service for an extended period of time, our operating revenues would decrease and we may have difficulty fulfilling our obligations under one or more of our existing contracts. The loss of revenue resulting from any such business interruption, and the cost and potentially long lead time and difficulties in sourcing a replacement aircraft, could have a material adverse effect on our business, results of operations and financial condition.

Our financial condition may suffer if we experience unanticipated costs as a result of ongoing lawsuits, claims and investigations related to alleged pricing practices or other legal and regulatory matters.

In the United Kingdom, several groups of named claimants have brought suit against British Airways Plc (“British Airways”) in connection with alleged improper matters related to the use of fuel surcharges and other rate components for air cargo services and are seeking damages allegedly arising from that conduct. British Airways has filed claims in the lawsuit against Polar Air Cargo LLC (“Old Polar”), formerly Polar Air Cargo, Inc., a consolidated subsidiary, and other carriers for contribution should British Airways be found liable to claimants.

In the Netherlands, Stichting Cartel Compensation, successor in interest to claims of various shippers, has filed suit in the district court in Amsterdam against British Airways, KLM, Martinair, Air France, Lufthansa and Singapore Airlines seeking recovery for damages purportedly arising from the same pricing practices at issue in the proceeding described above. In response, British Airways, KLM, Martinair, Air France and Lufthansa filed third-party indemnification lawsuits against Old Polar and Polar seeking indemnification in the event the defendants are found to be liable in the main proceedings.

12

If Old Polar, Polar or the Company were to incur an unfavorable outcome in the litigation described above or in similar litigation or a related investigation, it could have a material adverse effect on our business, results of operations and financial condition.

In addition to the litigation and investigations described above, we are subject to a number of Brazilian customs claims, as well as other claims, lawsuits and pending actions which we consider to be routine and incidental to our business (see Note 14 to our Financial Statements). If we were to receive an adverse ruling or decision on any such claims, it could have an adverse effect on our business, results of operations and financial condition.

Global trade flows are typically seasonal, and our business, including our ACMI customers’ business, experiences seasonal variations.

Global trade flows are typically seasonal in nature, with peak activity occurring during the retail holiday season, which generally begins in September/October and lasts through most of December. Our ACMI and CMI contracts generally have contractual utilization minimums that typically allow our customers to cancel an agreed-upon percentage of the guaranteed hours of aircraft utilization over the course of a year. Our ACMI and CMI customers often exercise those cancellation options early in the first quarter of the year, when the demand for air cargo capacity is historically low following the seasonal holiday peak in the fourth quarter of the previous year. While our revenues typically fluctuate seasonally as described above, a significant proportion of the costs associated with our business, such as debt service, aircraft rent, depreciation and facilities costs, are fixed and cannot easily be reduced to match the seasonal drop in demand. As a result, our net operating results are typically subject to a high degree of seasonality.

We may fail to realize the anticipated benefits of or fully integrate the acquisition of Southern Air, which could adversely affect our business, results of operations and financial condition, including the market price of our common stock.

Completing the integration of Southern Air with our other existing operations is subject to DOT approvals and authorizations, which may not be granted on a timely basis or at all. In addition, the Southern Air integration may expose us to operational challenges and risks, which could cause actual results to differ materially from anticipated results, including but not limited to: the diversion of management’s attention from our existing business; the assumption of unknown liabilities of the acquired business; the potential impairment of acquired identifiable intangible assets, including goodwill; the ability to effectively operate the 777 and 737 platforms or grow our business; the ability of the companies to maintain contracts that are important to our operations; the ability of the companies to fund and execute our business plans; our ability to attract, motivate and retain key employees; and our ability to attract and retain customers. If we do not receive the approvals and authorizations from the DOT on a timely basis or at all, or we otherwise fail to realize the anticipated benefits or fully integrate the acquisition of Southern Air, it could adversely affect our business, results of operations and financial condition, including the market price of our common stock.

As a U.S. government contractor, we are subject to a number of procurement and other rules and regulations that affect our business. A violation of these rules and regulations could lead to termination or suspension of our government contracts and could prevent us from entering into contracts with government agencies in the future.

To do business with government agencies, including the AMC, we must comply with, and are affected by, many rules and regulations, including those related to the formation, administration and performance of U.S. government contracts. These rules and regulations, among other things:

• require, in some cases, procurement from small businesses;

• require disclosure of all cost and pricing data in connection with contract negotiations;

13

• give rise to U.S. government audit rights;

• impose accounting rules that dictate how we define certain accounts, define allowable costs and otherwise govern our right to reimbursement under certain cost-based U.S. government contracts;

• establish specific health, safety and doing-business standards; and

• restrict the use and dissemination of information classified for national security purposes and the exportation of certain products and technical data.

These rules and regulations affect how we do business with our customers and, in some instances, add costs to our business. A violation of these rules and regulations could result in the imposition of fines and penalties or the termination of our contracts. In addition, the violation of certain other generally applicable rules and regulations could result in our suspension or debarment as a government contractor.

Fuel availability and price volatility could adversely affect our business and operations.

The price of aircraft fuel is unpredictable and can be volatile. While we have been able to reduce our exposure to fuel risk significantly, we do bear some risk of fuel exposure for our Charter operations. Our ACMI and CMI contracts require our customers to pay for aircraft fuel.

If fuel costs increase significantly, our customers may reduce the volume and frequency of cargo shipments or find less costly alternatives for cargo delivery, such as land and sea carriers. Such instances could have a material adverse impact on our business, results of operations and financial condition.

In the past, we have not experienced significant difficulties with respect to fuel availability. Although we do not currently anticipate a significant reduction in the availability of aircraft fuel, a number of factors, such as geopolitical uncertainties in oil-producing nations and shortages of and disruptions to refining capacity, make accurate predictions unreliable. Any inability to obtain aircraft fuel at competitive prices could have a material adverse impact on our business, results of operations and financial condition.

We are party to collective bargaining agreements covering pilots of Atlas and Southern Air and a collective bargaining agreement covering our Atlas and Polar flight dispatchers. This could result in higher labor costs and/or result in a work interruption or stoppage.

Pilots of Atlas and Southern Air and flight dispatchers of Atlas and Polar are represented by the IBT. We have a five-year CBA with our Atlas pilots, which became amendable in September 2016 and a four-year CBA with the Southern Air pilots, which became amendable in November 2016. We also have a five-year CBA with our Atlas and Polar flight dispatchers, which becomes amendable in November 2017. We are subject to risks of increased labor costs associated with having a partially unionized workforce, as well as a greater risk of work interruption or stoppage, which could negatively impact our ability to conduct business. We cannot provide assurance that disputes, including disputes with certified collective bargaining representatives of our employees, will not arise in the future or that any outcome of such disputes will result in an agreement on terms satisfactory to us.

Insurance coverage may become more expensive and difficult to obtain and may not be adequate to insure all of our risks. In addition, if our Dry Lease customers have inadequate insurance coverage or fail to fulfill their indemnification obligations, it could have a material adverse impact on our business, results of operations and financial condition.

Aviation insurance premiums historically have fluctuated based on factors that include the loss history of the industry in general, and the insured carrier in particular. Adverse events involving aircraft could result in increased insurance costs and could affect the price and availability of such coverage.

14

We participate in an insurance pooling arrangement with DHL and its partners. This allows us to obtain aviation hull and liability, war-risk hull and cargo loss, crew, third-party liability and hull deductible coverage at reduced rates from the commercial insurance providers. If we are no longer included in this arrangement for any reason or if pool members have coverage incidents, we may incur higher insurance costs.

There can be no assurance that we will be able to maintain our existing coverage on terms favorable to us, that the premiums for such coverage will not increase substantially or that we will not bear substantial losses and lost revenue from accidents or other adverse events. Substantial claims resulting from an accident in excess of related insurance coverage or a significant increase in our insurance expense could have a material adverse effect on our business, results of operations and financial condition. Additionally, while we carry insurance against the risks inherent to our operations, which we believe are consistent with the insurance arrangements of other participants in our industry, we cannot provide assurance that we are adequately insured against all risks, including coverage for weapons of mass destruction.

Lessees are required under our Dry Leases to indemnify us for, and insure against, liabilities arising out of the use and operation of the aircraft, including third-party claims for death or injury to persons and damage to property for which we may be deemed liable. Lessees are also required to maintain public liability, property damage and all-risk hull and war-risk hull insurance on the aircraft at agreed-upon levels. If our lessees’ insurance is not sufficient to cover all types of claims that may be asserted against us or if our lessees fail to fulfill their indemnification obligations, we would be required to pay any amounts in excess of our insurance coverage, which could have a material adverse impact on our business, results of operations and financial condition.

We rely on third parties to provide certain essential services. If these service providers do not deliver the high level of service and support required in our business, we may lose customers and revenue.

We rely on third parties to provide certain essential services on our behalf, including maintenance, ground handling and flight attendants. In certain locations, there may be very few sources, or sometimes only a single source, of supply for these services. If we are unable to effectively manage these third parties, they may provide inadequate levels of support which could harm our customer relationships and have an adverse impact on our operations and the results thereof. Any material problems with the quality and timeliness of our contracted services, or an unexpected termination of those services, could have a material adverse effect on our business, results of operations and financial condition.

Some of our aircraft are periodically deployed in potentially dangerous situations, which may result in business interruption or harm to our passengers, employees or contractors and/or damage to our aircraft/cargo.

Some of our aircraft are deployed in potentially dangerous locations and carry hazardous cargo incidental to the services we provide in support of our customers’ activities. Some areas through which our flight routes pass are subject to geopolitical instability, which increases the risk of death or injury to our passengers, employees or contractors, business interruption or a loss of, or damage to, our aircraft and/or its cargo. While we maintain insurance to cover injury to our passengers, employees and contractors as well as the loss/damage of aircraft/cargo, except for limited situations, we do not have insurance against the loss arising from business interruption. It may be difficult to replace lost or substantially damaged aircraft due to the high capital requirements and long delivery lead times for new aircraft or to locate appropriate in-service aircraft available for lease or sale. Any injury to passengers, employees or contractors or loss/damage of aircraft/cargo could have a material adverse impact on our business, results of operations and financial condition.

We could be adversely affected by a failure or disruption of our information technology systems.

We are heavily and increasingly dependent on technology to operate our business. The information technology systems on which we rely could be disrupted due to various events, some of which are beyond our

15

control, including natural disasters, power failures, terrorist attacks, equipment failures, software failures, computer viruses, security breaches and cyber attacks. We have taken numerous steps to implement business resiliency and cybersecurity to help reduce the risk of some of these potential disruptions. There can be no assurance, however, that the measures we have taken are adequate to prevent or remedy disruptions or failures of these systems. Any substantial or repeated failure of these systems could impact our operations and customer service, result in the loss of important data, loss of revenues, and increased costs, and generally harm our business. Moreover, a failure of certain of our vital systems could limit our ability to operate our flights for an extended period of time, which would have a material adverse impact on our business, results of operations and financial condition.

Our ability to utilize net operating loss carryforwards for U.S. income tax purposes may be limited. In addition, we operate in multiple jurisdictions and may become subject to a wide range of income and other taxes.

As of December 31, 2016, we had $991.0 million of federal net operating loss carryforwards for U.S. income tax purposes, net of unrecognized tax benefits and valuation allowance, which will expire through 2036, if not utilized. Section 382 of the Internal Revenue Code (“Section 382”) imposes an annual limitation on the amount of a corporation’s U.S. federal taxable income that can be offset by net operating loss carryforwards (“NOLs”) if it experiences an “ownership change”, as defined by Section 382. We experienced ownership changes, as defined by Section 382, in 2004 and 2009. Accordingly, the use of our NOLs generated prior to these ownership changes is subject to an annual limitation. In addition, the acquisition of Southern Air constituted an ownership change for that entity and resulted in a limitation on the use of its NOLs. If certain changes in our ownership occur prospectively, there could be an additional annual limitation on the amount of utilizable NOLs, which could have a material adverse impact on our business, results of operations and financial condition.

We operate in multiple jurisdictions and may become subject to a wide range of income and other taxes. If our operations become subject to significant income and other taxes, this could have a material adverse impact on our business, results of operations and financial condition.

Risks Related to Our ACMI Business

We depend on a limited number of significant customers for our ACMI business and the loss of one or more of such customers could materially adversely affect our business, results of operations and financial condition.

Our ACMI business depends on a limited number of customers, which has typically averaged between six and eight. We typically enter into long-term ACMI and CMI contracts with our customers. The terms of our existing contracts are scheduled to expire on a staggered basis. There is a risk that any one of our significant ACMI or CMI customers may not renew their contracts with us on favorable terms or at all, perhaps due to reasons beyond our control. For example, certain of our airline ACMI customers may not renew their ACMI contracts with us because they decide to exit the dedicated cargo business or as they take delivery of new aircraft in their own fleet. Select customers have the opportunity to terminate their long-term agreements in advance of the expiration date, following notice to allow for remarketing of the aircraft.

Entering into ACMI and CMI contracts with new customers generally requires a long sales cycle, and as a result, if our contracts are not renewed, and there is a resulting delay in entering into new contracts, it could have a material adverse impact on our business, results of operations and financial condition.

Our agreements with several ACMI and CMI customers require us to meet certain performance targets, including certain departure/arrival reliability standards. Failure to meet these performance targets could adversely affect our financial results.

Our ability to derive the expected economic benefits from our transactions with certain ACMI and CMI customers depends substantially on our ability to successfully meet strict performance standards and deadlines

16

for aircraft and ground operations, which become increasingly stringent over time. If we do not meet these requirements, we may not be able to achieve the projected revenues and profitability from these contracts, and we could be exposed to certain remedies, including termination of the agreements with Amazon and the BSA with DHL in the most extreme of circumstances, as described below.

Risks Related to the Agreements with Amazon

We may fail to realize the anticipated strategic and financial benefits of our relationship with Amazon.

Realization of the anticipated benefits from the agreements with Amazon is subject to a number of challenges and uncertainties, such as the timing of aircraft deliveries and unforeseen costs. If we fail to realize the expected benefits, it could adversely impact our business, results of operations and financial condition.

Our agreements with Amazon confer certain termination rights which, if exercised or triggered, may result in our inability to realize the full benefits of the agreements.

The agreements give Amazon the option to terminate in certain circumstances and upon the occurrence of certain events of default, including a change of control or our failure to meet certain performance requirements. In particular, Amazon will have the right to terminate without cause the agreement providing for CMI operations, with an effective termination date not earlier than January 1, 2018, upon providing us at least 180 days’ prior written notice of termination.

Upon termination, Amazon will generally, subject to certain exceptions, retain the warrants that have vested prior to the time of termination and, depending on the circumstances giving rise to the termination, may have the right to accelerated vesting of the remaining warrants upon a change of control of our company. Upon termination, Amazon or we may also have the right to receive a termination fee from the other party depending on the circumstances giving rise to the right of termination.

If Amazon exercises any of these termination rights, it could adversely impact our business, results of operations and financial condition.

Our future earnings and earnings per share, as reported under generally accepted accounting principles, could be adversely impacted by the warrants granted to Amazon.

The warrants granted to Amazon increase the number of diluted shares reported, which has an effect on our fully diluted earnings per share. Further, the warrants are presented as liabilities in our consolidated balance sheets and are subject to fair value measurement adjustments during the periods that they are outstanding. Accordingly, future fluctuations in the fair value of the warrants could adversely impact our results of operations.

If Amazon exercises its right to acquire shares of our common stock pursuant to the warrants, it will dilute the ownership interests of our then-existing stockholders and could adversely affect the market price of our common stock.

If Amazon exercises its right to acquire shares of our common stock pursuant to the warrants, it will dilute the ownership interests of our then-existing stockholders and reduce our earnings per share. In addition, any sales in the public market of any common stock issuable upon the exercise of the warrants by Amazon could adversely affect prevailing market prices of our common stock.

If Amazon exercises its right to acquire shares of our common stock pursuant to the warrants, Amazon may become a significant stockholder and may be entitled to appoint a director to our board of directors.

The warrants issued by us to Amazon grant Amazon the right to purchase up to 30%, in the aggregate, of our common stock on a post-issuance basis. If the warrants granted to Amazon are exercised, Amazon may

17

become a significant stockholder of our company. We have entered into a stockholders agreement with Amazon, pursuant to which Amazon’s ability to vote in its discretion will generally be capped at 14.9% with the remainder to be voted in accordance with our board of directors’ recommendation. In addition, under the stockholders agreement, Amazon will be entitled to appoint one director to our board of directors when Amazon owns 10% or more of our common stock. Until such time, Amazon will be entitled to designate a non-voting observer to our board of directors.

Risk Related to the BSA with DHL

Our agreements with DHL confer certain termination rights to them which, if exercised or triggered, may result in our inability to realize the full benefits of the BSA with DHL.

The BSA gives DHL the option to terminate the agreements for convenience by giving notice to us before the twelfth or fifteenth anniversary of the agreement’s commencement date, which was October 27, 2008. Further, DHL has a right to terminate the BSA for cause following a specified management resolution process if we default on our performance or we are unable to perform for reasons beyond our control. If DHL exercises any of these termination rights, it could adversely impact our business, results of operations and financial condition.

Risks Related to Our Charter Business

We derive a significant portion of our revenues from the AMC, and a substantial portion of these revenues have been generated pursuant to expansion flying, as opposed to fixed contract arrangements with the AMC. Revenues from the AMC are volatile and may decline from current levels.

As a percentage of our total operating revenue, revenue derived from the AMC was approximately 23.7% in 2016, 23.0% in 2015 and 18.7% in 2014. Historically, the revenues derived from expansion flights for the AMC significantly exceeded the value of the fixed flight component of our AMC contract.

Revenues from the AMC are typically derived from one-year contracts. Our AMC contract generally runs from October 1 through September 30 of the following year. Changes in national and international political priorities can significantly affect the volume of business from the AMC. Any decrease in U.S. military activity could reduce revenue from the AMC. In addition, our share of the total business from the AMC depends on several factors, including the total fleet size we commit to the CRAF program and the total number of aircraft deployed by our teaming arrangement partners and competitors in the program.

The AMC also holds all carriers to certain on-time performance requirements as a percentage of flights flown and, as a result of AMC demand volatility, it has become more difficult to comply with those requirements. To the extent that we fail to meet those performance requirements or if we fail to pass biannual AMC audits, revenues from our business with the AMC could decline through a suspension or termination of our AMC contract. Our revenues could also decline due to a reduction in the revenue rate we are paid by the AMC, a greater reliance by the AMC on its own fleet or a reduction in our allocation of AMC flying. Any reduction in our AMC flying could also negatively impact our Charter revenue from commercial customers for trips related to one-way AMC missions. We expect revenues and profitability from our business with the AMC to continue to remain volatile as the U.S. military continues to move troops and cargo to and from areas of conflict around the world. If we are unable to effectively deploy any resultant capacity during periods of reduced flying, it could have a material adverse effect on our business, results of operations and financial condition.

Our business with the AMC is sensitive to teaming arrangements which affect our relative share of AMC flying and the associated revenue. If one of our team members reduces its commitments or withdraws from the program, or if other carriers on other teams commit additional aircraft, our share of AMC flying may decline. In addition, any changes made to the commissions that we pay or receive for AMC flying or changes to the contracting mechanism could impact the revenues or profitability of this business.

Each year, the AMC allocates its air capacity requirements to different teams of participating airlines based on a mobilization value point system that is determined by the amount and types of aircraft that each team of

18

airlines pledges to the program. We participate in the program through a teaming arrangement with other airlines, led by FedEx. Our team is one of two major teams participating in the program during our current contract year. Several factors could adversely affect the amount of AMC flying that is allocated to us, including:

• changes in the contracting mechanism;

• the formation of new competing teaming arrangements;

• the withdrawal of any of our team’s current partners, especially FedEx;

• a reduction of the number of aircraft pledged by us or other members of our team; or

• increased participation of other carriers on other teams.

Any changes that would result in a reduction in our share of, or profitability from, AMC flying could have a material adverse effect on our business, results of operations and financial condition.

Risk Related to Our Dry Leasing Business

Any default by our Dry Lease customers, including (but not limited to) failure to make timely payments, failure to maintain insurance or failure to properly maintain our aircraft, could adversely affect our financial results

Our Dry Leasing business depends on the ability of our customers to satisfy their obligations under our leases, which may be affected by factors outside our control, including but not limited to: supply and demand of aircraft; competition; economic conditions; the price and availability of aircraft fuel; government regulations; the availability and cost of financing; failure to maintain insurance; and their overall financial condition and cash flow. Any default by our customers can result in reduced cash flow, termination of the lease and repossession of the related aircraft, any of which could have a material adverse effect on our business, results of operations and financial condition.

Dry Leasing customers are primarily responsible for maintaining our aircraft. Although we require many of our customers to pay us supplemental maintenance revenue, failure of a customer to perform required maintenance during the lease term could result in higher maintenance costs, a decrease in the value of our aircraft, the inability to re-lease aircraft at favorable rates, if at all, or impairment charges, which could have a material adverse effect on our business, results of operations and financial condition.

RISKS RELATED TO OUR INDUSTRY

The market for air cargo services is competitive and if we are unable to compete effectively, we may lose current customers or fail to attract new customers. We could also be adversely affected if a large number of long-haul freighter aircraft or freighter aircraft of different equipment types are introduced into the market.

Each of the markets in which we participate is competitive and fragmented. We offer a broad range of aviation services and our competitors vary by geographic market and type of service and include other international and domestic contract carriers, regional and national ground handling and logistics companies, internal cargo units of major airlines and third-party cargo providers. Competition in the air cargo and transportation market is influenced by several key factors, including quality, price and availability of assets and services. Regulatory requirements to operate in the U.S. domestic air cargo market have been reduced, facilitating the entry into domestic markets by non-U.S. air cargo companies. If we were to lose any major customers and/or fail to attract customers, it could have a material adverse effect on our business, results of operations and financial condition.

Additionally, an increase in the number of aircraft in the freight market could cause Yields and rates to fall and/or could negatively affect our customer base. If either circumstance were to occur, our business, results of operations and financial condition could be materially and adversely affected.

19

We are subject to extensive governmental regulations and failure to comply with these regulations in the U.S. and abroad, or the adoption of any new laws, policies or regulations or changes to such regulations, may have an adverse effect on our business.

Our operations and our customers’ operations are subject to complex aviation and transportation laws and regulations, including Title 49 of the U.S. Code, under which the DOT and the FAA exercise regulatory authority over air carriers. In addition, our business activities and our customers’ business activities fall within the jurisdiction of various other federal, state, local and foreign authorities, including the U.S. Department of Defense, the TSA, U.S. Customs and Border Protection, the U.S. Treasury Department’s Office of Foreign Assets Control and the U.S. EPA. In addition, other countries in which we operate have similar regulatory regimes to which we are subjected. These laws and regulations may require us to maintain and comply with the terms of a wide variety of certificates, permits, licenses, noise abatement standards, maintenance and other requirements and our failure to do so could result in substantial fines or other sanctions. These U.S. and foreign aviation regulatory agencies have the authority to modify, amend, suspend or revoke the authority and licenses issued to us for failure to comply with provisions of law or applicable regulations and may impose civil or criminal penalties for violations of applicable rules and regulations. Such fines or sanctions, if imposed, could have a material adverse effect on our mode of conducting business, results of operations and financial condition. In addition, U.S. and foreign governmental authorities may adopt, amend or interpret accounting standards, tax laws, regulations or treaties that could require us to take additional and potentially costly compliance steps or result in the grounding of some of our aircraft, which could increase our operating costs or result in a loss of revenues.

International aviation is increasingly subject to requirements imposed or proposed by foreign governments. This is especially true in the areas of transportation security, aircraft noise and emissions control, and greenhouse gas emissions. These may be duplicative of, or incompatible with U.S. government requirements, resulting in increased compliance efforts and expense.

Foreign governments also place temporal and other restrictions on the ability of their own airlines to use aircraft operated by other airlines. For example, the European Aviation Safety Agency (“EASA”) requires that the aircraft capacity secured from and operated by non-EU airlines meet internationally set standards and additional EASA requirements. These and other similar regulatory developments could have a material adverse effect on our business, results of operations and financial condition.

Initiatives to address global climate change may adversely affect our business and increase our costs.

To address climate change, governments continue to pursue various means to reduce aviation-related greenhouse gas emissions. Compliance with these or other measures that are ultimately adopted could result in substantial costs for us. For example, in October 2013, the ICAO reached a nonbinding agreement to develop global market-based measures to assist in achieving carbon-neutral growth from 2020 onward. In October 2016, the ICAO approved the CORSIA, which is designed to offset any annual increases in total carbon emissions from international civil aviation above a baseline level determined by the average of 2019 and 2020 emissions. Although various details regarding the implementation of CORSIA still need to be finalized, a pilot phase will run from 2021 to 2023 and, starting in 2019, the airlines of participating countries will begin monitoring and reporting fuel burn during international flights. As a result, for each year starting in 2021, covered airlines may need to purchase allowances to offset their assigned share of emissions overages.

Additionally, the EU continues to pursue a parallel track to address climate change through the EU ETS. Following the end of every year, to the extent the ETS applies, each airline must tender the number of allowances corresponding to carbon emissions generated by its covered flight activity during the year. If the airline’s flight activity during the year has produced carbon emissions exceeding the number of carbon emissions allowances that it has been awarded, the airline must acquire additional allowances from other airlines in the open market. In recognition of ICAO’s recent adoption of CORSIA, the ETS was suspended with respect to international aviation

20

through December 31, 2016; however, measures continue to remain applicable to intra-EU aviation. Although certain EU political leaders have stated that the EU is likely to extend this suspension beyond December 31, 2016, we cannot be certain whether or for how long the EU will do so.

In the U.S., various constituencies have continued to advocate for controls on greenhouse gas emissions. Previously, both houses of the U.S. Congress passed legislation to impose a carbon-related tax on fuel sold to airlines and other entities; however, a bill has not yet been signed into law. On August 15, 2016, the EPA issued a final rule finding that greenhouse gas emissions from aircraft cause or contribute to air pollution that may reasonably be anticipated to endanger public health and welfare. This finding could lead to EPA regulation of greenhouse gas emissions from aircraft.

It is possible that these or similar climate change measures will be imposed in a manner adversely affecting airlines. The costs of complying with potential new environmental laws or regulations could have a material adverse effect on our business, results of operations and financial condition.

The airline industry is subject to numerous security regulations and rules that increase costs. Imposition of more stringent regulations and rules than those that currently exist could materially increase our costs.

The TSA has increased security requirements in response to increased levels of terrorist activity, and has adopted comprehensive new regulations governing air cargo transportation, including all-cargo services, in such areas as cargo screening and security clearances for individuals with access to cargo. Additional measures, including a requirement to screen cargo, have been proposed, which, if adopted, may have an adverse impact on our ability to efficiently process cargo and would increase our costs and those of our customers. The cost of compliance with increasingly stringent regulations could have a material adverse effect on our business, results of operations and financial condition.

Our future operations might be constrained if FAA flight and duty time rules are expanded to apply to all-cargo operations.

In December 2011, the FAA adopted a rule to impose new flight and duty time requirements with the stated goal of reducing pilot fatigue. The rule took effect on January 14, 2014 and applies to our passenger operations but not to our all-cargo operations. Should the FAA decide either on its own initiative or pursuant to Congressional directive to change the final rule to include all-cargo operations, it could result in a material increase in our crew costs. It could also have a material adverse impact on our business, results of operations and financial condition by limiting crew scheduling flexibility and increasing operating costs, especially with respect to long-range flights.

RISKS RELATED TO OUR LEASE AND DEBT OBLIGATIONS

Our substantial lease and debt obligations, including aircraft leases and other obligations, could impair our financial condition and adversely affect our ability to raise additional capital to fund our aircraft purchases and conversions, operations or other capital requirements, all of which could limit our financial resources and ability to compete, and may make us vulnerable to adverse economic events.

As of December 31, 2016, we had total debt obligations of approximately $1.9 billion and total aircraft operating leases and other lease obligations of $0.9 billion. These obligations have increased and are expected to increase further as we enter into financing arrangements for 767-300 aircraft purchases and passenger-to-freighter conversions, GEnx engine upgrades and other capital requirements. We cannot provide assurance that we will be able to obtain such financing arrangements or on terms attractive to us. Our outstanding financial obligations could have negative consequences, including:

• making it more difficult to satisfy our debt and lease obligations;

• requiring us to dedicate a substantial portion of our cash flows from operations for interest, principal and lease payments and reducing our ability to use our cash flows to fund working capital and other general corporate requirements;

21

• increasing our vulnerability to general adverse economic and industry conditions; and

• limiting our flexibility in planning for, or reacting to, changes in our business and in our industry.

Our ability to service our debt and meet our lease and other obligations as they come due is dependent on our future financial and operating performance. This performance is subject to various factors, including factors beyond our control, such as changes in global and regional economic conditions, changes in our industry, changes in interest or currency exchange rates, the price and availability of aircraft fuel and other costs, including labor and insurance. Accordingly, we cannot provide assurance that we will be able to meet our debt service, lease and other obligations as they become due and our business, results of operations and financial condition could be adversely affected under these circumstances.

Certain of our debt obligations contain a number of restrictive covenants. In addition, many of our debt and lease obligations have cross-default and cross-acceleration provisions.

Restrictive covenants in certain of our debt and lease obligations, under certain circumstances, could impact our ability to:

• borrow under certain financing arrangements;

• consolidate or merge with or into other companies or sell substantially all our assets;

• expand significantly into lines of businesses beyond existing business activities or those which are cargo-related and/or aviation-related and similar businesses; and/or

• modify the terms of debt or lease financing arrangements.

In certain circumstances, a covenant default under one of our debt instruments could cause us to be in default of other obligations as well. Any unremedied defaults could lead to an acceleration of the amounts owed and potentially could cause us to lose possession or control of certain aircraft, either of which could have a material adverse effect on our business, results of operations and financial condition.

We may not have the ability to raise the funds necessary to settle conversions of our convertible notes or to repurchase the convertible notes upon either a fundamental change or a make-whole fundamental change, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of the convertible notes.

We issued convertible senior notes in June 2015 (the “Convertible Notes”), which contain conditional conversion features that allow the holders of the Convertible Notes the option to convert if certain trading conditions are met or upon the occurrence of specified corporate events. In the event a conditional conversion feature of the Convertible Notes is triggered, holders of Convertible Notes will be entitled to convert the Convertible Notes at any time during specified periods at their option. If one or more holders elect to convert their Convertible Notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock, we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to convert their Convertible Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the Convertible Notes as current on the balance sheet instead of as noncurrent, which could result in a material reduction of our net working capital.

The holders of the Convertible Notes also may require us to repurchase their Convertible Notes upon the occurrence of a fundamental change (as defined in the indenture governing the Convertible Notes) at a price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest, if any. However, we may not have enough available cash to fund these obligations or be able to obtain financing on favorable terms, or at all, at the time we are required to make repurchases of Convertible Notes surrendered or Convertible Notes being converted. Our failure to repurchase Convertible Notes at a time when

22

the repurchase is required by the indenture or to pay any cash payable on future conversions of the Convertible Notes as required by the indenture would constitute a default under the indenture, which could result in acceleration of the principal amount of the notes and additional funding obligations by us.

In addition, if a make-whole fundamental change (as defined in the indenture governing the Convertible Notes), including specified corporate transactions, occurs prior to the maturity date, under certain circumstances, it would increase the conversion rate. The increase in the conversion rate would be determined based on the date on which the specified corporate transaction becomes effective and the price paid (or deemed to be paid) per share of our common stock in such transaction, but in no event would increase to greater than 17.8922 shares of common stock per $1,000 of principal, subject to adjustment in the same manner as the conversion rate. The increase in the conversion rate for Convertible Notes converted in connection with a make-whole fundamental change may result in us having to pay out additional cash in respect of the Convertible Notes upon conversion, or result in additional dilution to our shareholders if the conversion is settled, at our election, in shares of our common stock.

The Convertible Note hedge and warrant transactions may affect the value of our common stock.

In connection with the Convertible Notes offering, we entered into Convertible Note hedge transactions with option counterparties. The Convertible Note hedge transactions are expected generally to reduce the potential dilution to our common stock upon any conversion of notes and/or offset any cash payments we are required to make in excess of the principal amount of converted notes, as the case may be. We also entered into warrant transactions with the option counterparties. However, the warrant transactions could separately have a dilutive effect on our earnings per share to the extent that the market price per share of our common stock exceeds the applicable strike price of the warrants. Accordingly, when the Convertible Note hedge transactions and the warrant transactions are taken together, the extent to which the Convertible Note hedge transactions reduce the potential dilution to our common stock (or the cash payments in excess of the principal amount of the notes) upon conversion of the notes is effectively capped by the warrant transaction at the strike price of the warrant.

The option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various hedging transactions, including (without limitation) derivatives, with respect to our common stock and/or purchasing or selling our common stock or other securities of ours in secondary market transactions prior to the maturity of the notes (and are likely to do so during any observation period related to a conversion of notes). This activity could cause or avoid an increase or a decrease in the market price of our common stock.

RISKS RELATED TO OWNERSHIP OF OUR COMMON STOCK

U.S. citizenship requirements may limit common stock voting rights.

Under U.S. federal law and DOT requirements, we must be owned and actually controlled by “citizens of the United States,” a statutorily defined term requiring, among other things, that not more than 25% of our issued and outstanding voting stock be owned and controlled, directly or indirectly, by non-U.S. citizens. The DOT periodically conducts airline citizenship reviews and, if it finds that this requirement is not met, may require adjustment of the voting rights of the airline’s issued shares.

As one means to effect compliance, our certificate of incorporation and by-laws provide that the failure of non-U.S. citizens to register their shares on a separate stock record, which we refer to as the “Foreign Stock Record,” results in a suspension of their voting rights. Our by-laws further limit the number of shares of our capital stock that may be registered on the Foreign Stock Record to 25% of our issued and outstanding shares. Registration on the Foreign Stock Record is made in chronological order based on the date we receive a written request for registration. As a result, if a non-U.S. citizen acquires shares of our common stock and does not or is not able to register those shares on our Foreign Stock Record, they may lose their ability to vote those shares.

23

Provisions in our restated certificate of incorporation and by-laws and Delaware law, and our issuance of warrants to Amazon, might discourage, delay or prevent a change in control of the Company and, therefore, depress the trading price of our common stock.

Provisions of our restated certificate of incorporation, by-laws and Delaware law may render more difficult or discourage any attempt to acquire our company, even if such acquisition may be believed to be favorable to the interests of our stockholders. These provisions may also discourage bids for our common stock at a premium over market price or adversely affect the market price of our common stock. In addition, the vesting of warrants issued by us to Amazon will generally, subject to certain exceptions, be accelerated upon a change of control of our company, which may discourage attempts to acquire our company.

Our common stock share price is subject to fluctuations in value.

The trading price of our common shares is subject to material fluctuations in response to a variety of factors, including quarterly variations in our operating results, conditions of the airfreight market and global economic conditions or other events and factors that are beyond our control.

In the past, following periods of significant volatility in the overall market and in the market price of a company’s securities, securities class action litigation has been instituted against these companies in some circumstances. If this type of litigation were instituted against us following a period of volatility in the market price for our common stock, it could result in substantial costs and a diversion of our management’s attention and resources, which could have a material adverse effect on our business, results of operations and financial condition.

The following discussion should be read in conjunction with the Financial Statements included in Item 8 of this report.

Business Overview

We are a leading global provider of outsourced aircraft and aviation operating services. We operate the world’s largest fleet of 747 freighters and provide customers a broad array of 747, 777, 767, 757 and 737 aircraft

29

for domestic, regional and international cargo and passenger applications. We provide unique value to our customers by giving them access to highly reliable new production freighters that deliver the lowest unit cost in the marketplace combined with outsourced aircraft operating services that we believe lead the industry in terms of quality and global scale. Our customers include express delivery providers, e-commerce retailers, airlines, freight forwarders, the U.S. military and charter brokers. We provide global services with operations in Africa, Asia, Australia, Europe, the Middle East, North America and South America.

We believe that the following competitive strengths will allow us to capitalize on opportunities that exist in the global airfreight industry:

Market leader with leading-edge technology and differentiated, value-creating solutions

The 747-8F and 777-200LRF aircraft are two of the most efficient long-haul wide-body commercial freighters available and we are currently the only operator offering these aircraft under ACMI and CMI agreements. Our operating model deploys our aircraft to drive maximum utilization and value from our fleet. The scale of our fleet enables us to have aircraft available globally to respond to our customers’ needs, both on a planned and ad hoc basis. We believe this provides us with a commercial advantage over our competitors that operate smaller and less flexible fleets.

Our Dry Leasing business is primarily focused on a portfolio of six 777-200LRF aircraft and our growing fleet of 767-300 freighter aircraft for regional and domestic applications. These aircraft are dry leased to customers on a long-term basis, which further diversifies our business mix and enhances our predictable, long-term revenue and earnings streams.

Stable base of contractual revenue and reduced operational risk

Our focus on providing long-term contracted aircraft and operating solutions to customers stabilizes our revenues and reduces our operational risk. ACMI and CMI contracts with customers generally range from two to seven years, although some contracts have shorter or longer durations. Dry Leasing contracts with customers generally range from five to twelve years. Under ACMI, CMI and Dry Leasing, our customers assume fuel, demand and price risk resulting in reduced operational risk for AAWW. ACMI, CMI and Dry Leasing contracts typically provide us with a guaranteed minimum level of revenue and target level of profitability.

Focus on asset optimization

By managing the largest fleet of outsourced freighter aircraft, we achieve significant economies of scale in areas such as aircraft maintenance, crew efficiency, crew training, inventory management and purchasing.

Our mix of aircraft is closely aligned with our customer needs. By providing the broadest array of 747, 777, 767, 757 and 737 aircraft for domestic, regional and international applications, we believe that we are well-suited to meet the current and anticipated requirements of our customers.

We continually evaluate our fleet to ensure that we offer the most efficient and effective mix of aircraft to meet our customers’ needs. Our service model is unique in that we offer a portfolio of operating solutions that complement our freighter aircraft businesses. We believe this allows us to improve the returns we generate from our asset base by allowing us to flexibly redeploy aircraft to meet changing market conditions, ensuring the maximum utilization of our fleet. Our Charter services complement our ACMI services by allowing us to increase aircraft utilization during open time and to react to changes in demand and Yield in these segments. We have employees situated around the globe who closely monitor demand for commercial charter services in each region, enabling us to redeploy available aircraft quickly. We also endeavor to manage our portfolio to stagger contract terms, which mitigates our remarketing risks and aircraft down time.

30

Long-term strategic customer relationships and unique innovative service offerings

We combine the global scope and scale of our efficient aircraft fleet with high-quality, cost-effective operations and premium customer service to provide unique, fully integrated and reliable solutions for our customers. We believe this approach results in customers that are motivated to seek long-term relationships with us. This has historically allowed us to command higher prices than our competitors in several key areas. These long-term relationships help us to build resilience into our business model.

Our customers have access to our innovative solutions, such as inter-operable crews, flight scheduling, fuel-efficiency planning, and maintenance spare coverage, which, we believe, set us apart from other participants in the outsourced aircraft and aviation operating services market. Furthermore, we have access to valuable operating rights to restricted markets such as Brazil, Japan and China. We believe our freighter services allow our customers to effectively expand their capacity and operate dedicated freighter aircraft without simultaneously taking on exposure to fluctuations in the value of owned aircraft and, in the case of our ACMI and CMI contracts, long-term expenses relating to crews and maintenance. Dedicated freighter aircraft enable schedules to be driven by cargo rather than passenger demand (for those customers that typically handle portions of their cargo operations via belly capacity on passenger aircraft), which we believe allows our customers to drive higher contribution from cargo operations.

We are focused on providing safe, secure and reliable services. Atlas, Polar and Southern Air all have successfully completed the International Air Transport Association’s Operational Safety Audit (IOSA), a globally recognized safety and quality standard.

We provide outsourced aircraft and aviation services to some of the world’s premier express delivery providers, e-commerce retailers, airlines and freight forwarders. We will take advantage of opportunities to maintain and expand our relationships with our existing customers, while seeking new customers and new geographic markets.

During 2016, we significantly expanded our CMI and Dry Leasing services with long-term contracts with DHL and Amazon. In April 2016, we expanded our relationship with DHL through the acquisition of Southern Air which provided us with immediate entry into the 777 and 737 aircraft operating platforms, with ten aircraft and the potential for developing additional business with existing and new customers. In May 2016, we entered into agreements with Amazon, which involve, among other things, the lease and operation of 20 Boeing 767-300 freighter aircraft. The first two aircraft were placed in service in August 2016 and February 2017, while the remainder are expected to be placed in service by the end of 2018.

Experienced management team

Our management team has extensive operating and leadership experience in the airfreight, airline, aircraft leasing and logistics industries at companies such as United Airlines, US Airways, Lufthansa Cargo, GE Capital Aviation Services, Air Canada, Ansett Worldwide Aviation Services, Canadian Airlines, Cathay Pacific, Continental Airlines, ICF International, Seabury Group LLC, ASTAR Air Cargo and KLM Cargo, as well as the United States Army, Navy, Air Force and Federal Air Marshal Service. Our management team is led by William J. Flynn, who has over 40 years of experience in freight and transportation and has held senior management positions with several transportation companies. Prior to joining AAWW ten years ago, Mr. Flynn was President and CEO of GeoLogistics, a global transportation and logistics enterprise.

31

Business Strategy

Our strategy includes the following:

Focus on securing long-term customer contracts

We will continue to focus on securing long-term contracts with customers, which provide us with stable revenue streams and predictable margins. In addition, these agreements limit our direct exposure to fuel and other costs and mitigate the risk of fluctuations in both Yield and demand in the airfreight business, while also improving the overall utilization of our fleet.

Aggressively manage our fleet with a focus on leading-edge aircraft

We continue to actively manage our fleet of leading-edge wide-body freighter aircraft to meet customer demands. Our 747-8F and 777-200LRF freighter aircraft are primarily utilized in our ACMI business, while our 747-400s are utilized in our ACMI and Charter business. We aggressively manage our fleet to ensure that we provide our customers with the most efficient aircraft to meet their needs.

Our Dry Leasing business is primarily focused on a portfolio of six modern, efficient 777-200LRF aircraft and our growing fleet of 767-300 freighter aircraft for regional and domestic applications. We will continue to explore opportunities to invest in additional aircraft, such as the 20 767-300 freighter aircraft committed to Amazon.

Drive significant and ongoing productivity improvements

We continue to enhance our organization through a cost saving and productivity enhancing initiative called “Continuous Improvement.” We created a separate department to drive the process and to involve all areas of the organization in the effort to reexamine, redesign and improve the way we do business.

Selectively pursue and evaluate future acquisitions and alliances

From time to time, we explore business combinations, such as our acquisition of Southern Air, and alliances with e-commerce providers, such as our agreements with Amazon, other cargo airlines, services providers, dry leasing and other companies to enhance our competitive position, geographic reach and service portfolio.

Appropriately managing capital allocation and returning capital to shareholders

Our commitment to creating, enhancing and returning value to our shareholders reflects a disciplined and balanced capital allocation strategy. Our focus is on maintaining a strong balance sheet, investing in modern efficient assets, and returning capital to shareholders.

Business Developments

Our ACMI results for 2016, compared with 2015, were impacted by the following events:

• In March 2015, we began ACMI flying one additional 747-8F aircraft for DHL.

• In January, February, March and April of 2015, we began CMI flying four additional 767-200 freighters owned by DHL in its North American network.

• In July 2015, we began ACMI flying one additional 747-400F aircraft for DHL, increasing the number of 747 freighter aircraft in ACMI service for DHL to thirteen.

• In December 2015 and February 2016, we began CMI flying for DHL two 767-300 freighter aircraft, Dry Leased from Titan, in DHL’s North American network, increasing the number of freighter aircraft in CMI service for DHL to twelve.

32

• In April 2016, we acquired Southern Air, which currently operates five 777-200LRF and five 737-400F aircraft under CMI agreements for DHL.

• In August 2016, we began CMI flying for Amazon the first of 20 Boeing 767-300 freighter aircraft Dry Leased from Titan. In February 2017, we placed the second 767-300 freighter aircraft into service. The remaining aircraft are expected to be placed in service by the end of 2018.

In November 2016, we entered into an agreement with Nippon Cargo Airlines to operate a 747-400 freighter aircraft on its transpacific routes. We began flying during the first quarter of 2017.

In August 2016, we entered into a long-term ACMI agreement with FedEx to provide five 747-400 freighter aircraft for peak flying seasons beginning in 2017.

In February 2017, we entered into an agreement with Asiana Cargo to provide a 747-400 freighter aircraft for its transpacific routes. We began flying during the first quarter of 2017.

Charter results for 2016 were impacted, compared with 2015, when Yields benefited from the U.S. West Coast port disruption. This impact was partially offset by an increase in Block Hours during 2016, primarily reflecting increased cargo and passenger demand from the AMC.

In December 2015 and February 2016, we began Dry Leasing two 767-300 converted freighter aircraft to DHL on a long-term basis. In March 2016, we also Dry Leased a 737-800 passenger aircraft on a long-term basis to a customer following its scheduled return. In August 2016 and February 2017, we began Dry Leasing two 767-300 converted freighter aircraft to Amazon on a long-term basis.

Operating Revenue

The following table compares our Operating Revenue (in thousands):

	2016			2015		Inc/(Dec)			% Change
Operating Revenue
ACMI	$	834,997		$	791,442	$	43,555			5.5	%

Total Operating Revenue	$	1,839,627		$	1,822,659	$	16,968			0.9	%

NM represents year-over-year changes that are not meaningful.

ACMI

	2016		2015		Inc/(Dec)			% Change
ACMI Block Hours		151,919		126,206		25,713			20.4	%
ACMI Revenue Per Block Hour	$	5,496	$	6,271	$	(775	)		(12.4	)%

ACMI revenue increased $43.6 million, or 5.5%, primarily due to increased flying, partially offset by reduced Revenue per Block Hour. The increase in Block Hours reflects the impact from the Southern Air Acquisition and increased 767 CMI flying, partially offset by the temporary redeployment of 747-8F aircraft to the Charter segment. The decrease in Revenue per Block Hour primarily reflects the 777-200 and 737-400 CMI flying from the Southern Air Acquisition, increased 767 CMI flying and the temporary redeployment of 747-8F aircraft to Charter in 2016.

Charter

	2016		2015		Inc/(Dec)			% Change
Charter Block Hours:
Cargo		40,376		35,463		4,913			13.9	%
Passenger		16,403		14,776		1,627			11.0	%
Total		56,779		50,239		6,540			13.0	%
Charter Revenue Per Block Hour:
Cargo	$	14,861	$	17,655	$	(2,794	)		(15.8	)%
Passenger	$	17,191	$	19,130	$	(1,939	)		(10.1	)%
Total	$	15,534	$	18,089	$	(2,555	)		(14.1	)%

Charter revenue decreased $26.8 million, or 2.9%, primarily due to a decrease in Revenue per Block Hour, partially offset by an increase in Block Hours. The decrease in Revenue per Block Hour was primarily driven by a reduction in fuel prices in 2016 and the impact of higher rates resulting from the U.S. West Coast port disruption in 2015, partially offset by the temporary redeployment of 747-8F aircraft from the ACMI segment. The increase in Charter Block Hours was primarily driven by an increase in cargo and passenger demand from the AMC.

Dry Leasing

Dry Leasing revenue decreased $1.4 million, or 1.3%, primarily due to lower revenue from maintenance payments received in 2016 related to the scheduled return of aircraft. Revenue from maintenance payments is based on the maintenance condition of the aircraft at the end of the lease. Partially offsetting this decrease was revenue from the placement of two 767-300 converted freighter aircraft with DHL in December 2015 and February 2016, and one 767-300 converted freighter aircraft with Amazon in August 2016.

Transaction-related expenses		22,071			—		22,071			NM
Other		142,733			234,073		(91,340	)		(39.0	)%
Total Operating Expenses	$	1,671,316		$	1,699,154

Salaries, wages and benefits increased $73.0 million, or 20.8%, primarily driven by $23.5 million of expense for a change in control, as defined under certain benefit plans, related to the Amazon transaction (see Note 7 to our Financial Statements), the impact of the Southern Air Acquisition, increased flying and increased crewmember costs related to Amazon and other fleet growth initiatives.

Aircraft fuel decreased $58.3 million, or 17.5%, primarily due to fuel price decreases, partially offset by increased fuel consumption. Fuel consumption increased primarily reflecting the increase in Charter Block Hours operated. We do not incur fuel expense in our ACMI or Dry Leasing businesses as the cost of fuel is borne by the customer. Average fuel cost per gallon and fuel consumption for 2016 and 2015 were:

	2016		2015		Inc/(Dec)			% Change
Average fuel cost per gallon	$	1.68	$	2.27	$	(0.59	)		(26.0	)%
Fuel gallons consumed (000s)		163,862		147,081		16,781			11.4	%

Maintenance, materials and repairs increased by $3.8 million, or 1.9%, primarily reflecting increases of $7.1 million for 777-200 aircraft, $5.1 million for 767 aircraft and $2.3 million for 747-8F aircraft, partially offset by a decrease of $12.6 million for 747-400 aircraft. Heavy Maintenance expense on 747-400 aircraft decreased $10.2 million primarily due to a decrease in the number of engine overhauls, partially offset by an increase in the number of C Checks. Heavy Maintenance expense on 747-8F aircraft decreased $5.9 million primarily due to a decrease in unscheduled engine repairs. Line Maintenance increased by $7.7 million on 747-8F aircraft, $5.0 million on 767 aircraft and $4.1 million on 747-400 aircraft due to increased flying and additional repairs performed. Line maintenance also increased $4.6 million on 777-200 aircraft related to the Southern Air Acquisition. Non-heavy Maintenance on 747-400 aircraft decreased $6.4 million as a result of fewer events. Heavy airframe maintenance checks and engine overhauls impacting Maintenance, materials and repairs for 2016 and 2015 were:

Heavy Maintenance Events	2016		2015		Inc/(Dec)
747-8F C Checks		4		4		—
747-400 C Checks		9		5		4
747-400 D Checks		4		4		—
767 C Checks		1		1		—
CF6-80 engine overhauls		3		10		(7	)

36

Depreciation and amortization increased $20.1 million, or 15.6%, primarily due to additional aircraft operating in 2016.

Travel increased $25.0 million, or 24.3%, primarily due to the impact of the Southern Air Acquisition, increased flying and higher rates related to crewmember travel.

Passenger and ground handling services increased $6.5 million, or 7.8%, primarily due to increased flying.

Navigation fees, landing fees and other rent decreased $20.9 million, or 21.0%, primarily due to a reduction in purchased capacity from the subcontracting of certain Charter flights.

Special charge in 2016 represents a $10.1 million impairment loss on engines held for sale (see Note 5 to our Financial Statements). We may sell additional flight equipment, which could result in additional charges in future periods. Special charge in 2015 resulted from an $8.3 million impairment loss on engines held for sale and a $7.7 million charge for the early termination of high-rate operating leases for two engines.

Transaction-related expenses in 2016 relate to the Southern Air Acquisition and Amazon transaction, which primarily include: certain compensation costs, including employee termination benefits; professional fees; and integration costs (see Notes 4 and 7 to our Financial Statements).

Other decreased $91.3 million, or 39.0%, primarily due to the settlement of the U.S. class action litigation and related legal fees in 2015 (see Note 14 to our Financial Statements), partially offset by an accrual for legal matters and the Southern Air Acquisition in 2016.

Non-operating Expenses (Income)

The following table compares our Non-operating Expenses (Income) (in thousands):

	2016			2015			Inc/(Dec)			% Change
Non-operating Expenses (Income)
Interest income	$	(5,532	)	$	(12,554	)	$	(7,022	)		(55.9	)%
Interest expense		84,650			96,756			(12,106	)		(12.5	)%
Capitalized interest		(3,313	)		(1,027	)		2,286			NM
Loss on early extinguishment of debt		132			69,728			(69,596	)		NM
Unrealized loss on financial instruments		2,888			—			(2,888	)		NM
Gain on investments		—			(13,439	)		(13,439	)		NM
Other expense		70			1,261			(1,191	)		NM

Interest income decreased $7.0 million, or 55.9%, primarily due to a decrease in PTCs.

Interest expense decreased $12.1 million, or 12.5%, primarily due to a decrease in interest rates resulting from the refinancing of higher-rate EETCs with lower-rate Convertible Notes in 2015 and a reduction in our average debt balances, reflecting payments of debt.

Loss on early extinguishment of debt was related to the refinancing of five EETCs with lower-rate Convertible Notes during the third quarter of 2015.

Unrealized loss on financial instruments represents the change in fair value of the Amazon Warrant during 2016 (see Note 7 to our Financial Statements).

Gain on investments was related to the early redemption of certain PTC investments resulting from the refinancing of five EETCs with lower-rate Convertible Notes during the third quarter of 2015.

37

Income taxes.    Our effective income tax rates were an expense of 52.3% in 2016 and a benefit of 142.3% for 2015. The effective income tax rate for 2016 differed from the U.S. statutory rate primarily due to a nondeductible customer incentive and to nondeductible compensation expenses resulting from a change in control, as defined under certain of the Company’s benefits plans, both related to the Amazon transaction (see Note 7 to our Financial Statements). The effective income tax rate for 2015 differed from the U.S. federal statutory rate primarily due to income tax benefits related to ETI. The effective rates for both periods were impacted by our assertion to indefinitely reinvest the net earnings of foreign subsidiaries outside the U.S. (see Note 11 to our Financial Statements).

Segments

We use an economic performance metric (“Direct Contribution”) representing Income (loss) from continuing operations before income taxes excluding the following: Special charges, Transaction-related expenses, nonrecurring items, Losses (gains) on the disposal of aircraft, Losses on early extinguishment of debt, Unrealized losses (gains) on financial instruments, Gains on investments and Unallocated income and expenses, net. Direct Contribution shows the profitability of each segment after allocation of direct operating and ownership costs. We operate our service offerings through the following reportable segments: ACMI, Charter and Dry Leasing. The following table compares the Direct Contribution for our reportable segments (see Note 13 to our Financial Statements for the reconciliation to Operating income) (in thousands):

	2016		2015		Inc/(Dec)			% Change
Direct Contribution:
ACMI	$	200,563	$	185,615	$	14,948			8.1	%
Charter		133,727		124,808		8,919			7.1	%
Dry Leasing		33,114		42,023		(8,909	)		(21.2	)%
Total Direct Contribution	$	367,404	$	352,446	$	14,958			4.2	%
Unallocated income and expenses, net	$	242,768	$	294,451	$	(51,683	)		(17.6	)%

ACMI Segment

ACMI Direct Contribution increased $14.9 million, or 8.1%, primarily due to the Southern Air Acquisition and lower Heavy Maintenance expense. Partially offsetting these items were the temporary redeployment of 747-8F aircraft to the Charter segment, increases in crewmember costs related to Amazon and other fleet growth initiatives, and higher rates related to crewmember travel.

Charter Segment

Charter Direct Contribution increased $8.9 million or 7.1%, primarily due to an increase in passenger and cargo demand from the AMC and the temporary redeployment of 747-8F aircraft from the ACMI segment. Partially offsetting these increases was the impact of the U.S. West Coast port disruption in 2015.

Dry Leasing Segment

Dry Leasing Direct Contribution decreased $8.9 million, or 21.2%, primarily due to lower revenue from maintenance payments to us in 2016 related to the scheduled return of aircraft. Partially offsetting this decrease was contribution related to the placement of two 767-300 converted freighter aircraft with DHL in December 2015 and February 2016, and one 767-300 converted freighter aircraft with Amazon in August 2016.

38

Unallocated income and expenses, net

Unallocated income and expenses, net decreased $51.7 million, or 17.6%, primarily due to the settlement of the U.S. class action litigation and related legal fees in 2015. Partially offsetting these items were $23.5 million of compensation expenses for a change in control, as defined under certain benefit plans, related to the Amazon transaction (see Note 7 to our Financial Statements) and the impact of the Southern Air Acquisition in 2016.

ACMI Revenue Per Block Hour	$	6,271	$	6,764	$	(493	)		(7.3	)%

ACMI revenue increased $13.4 million, or 1.7%, primarily due to increased flying, partially offset by reduced Revenue per Block Hour. The increase in Block Hours was primarily driven by one incremental 747-8F aircraft and one incremental 747-400F aircraft entering ACMI service, four incremental 767-200F aircraft entering CMI service and improvements in ACMI aircraft utilization. The decrease in Revenue per Block Hour reflects the impact of higher Revenue per Block Hour in 2014 resulting from customers that flew below their contractual minimums, payments received in 2014 related to a customer’s return of aircraft, and the impact of increased CMI flying in 2015.

Charter	$	18,089	$	20,285	$	(2,196	)		(10.8	)%

Charter revenue increased $2.1 million, or 0.2%, primarily driven by an increase in both cargo and passenger flying, partially offset by a decrease in Revenue per Block Hour. The increase in Charter Block Hours was primarily driven by increased cargo and passenger demand from the AMC and increased commercial cargo demand, which was enhanced by the U.S. West Coast port disruption in early 2015. The decrease in Charter Revenue per Block Hours was primarily driven by the impact of lower fuel prices, partially offset by higher Yields, excluding fuel.

40

Dry Leasing

Dry Leasing revenue increased $7.2 million, or 7.2%, primarily due to revenue from maintenance payments related to the scheduled returns of a 737-800 passenger aircraft in February 2015 and a 757-200 cargo aircraft in April 2015, partially offset by a reduction in the number of Dry Leased aircraft following the sale of the returned 737-800 passenger aircraft during the first quarter of 2015.

Operating Expenses

Total Operating Expenses	$	1,699,154	$	1,623,226

Salaries, wages and benefits increased $40.2 million, or 12.9%, primarily driven by increases to crewmember and ground staff costs due to higher Block Hours, crew training related to our investment in fleet growth and key initiatives.

Aircraft fuel decreased $70.9 million, or 17.5%, primarily due to fuel price decreases, partially offset by increased fuel consumption reflecting the increase in Charter Block Hours operated. We do not incur fuel expense in our ACMI or Dry Leasing businesses as the cost of fuel is borne by the customer. Average fuel cost per gallon and fuel consumption for 2015 and 2014 were:

	2015		2014		Inc/(Dec)			% Change

41

Maintenance, materials and repairs decreased by $1.2 million, or 0.6%, reflecting a decrease of $12.6 million for 747-400 aircraft, partially offset by an increase of $7.5 million for 747-8F aircraft and $3.9 million for 767 aircraft. Heavy Maintenance expense on 747-400 aircraft decreased approximately $22.5 million due to a decrease in the number of C and D Checks, and the number of engine overhauls, partially offset by an increase of $6.1 million in Non-heavy Maintenance. Heavy Maintenance expense on 747-8F aircraft increased $5.1 million primarily due to an increase in unscheduled engine repairs, partially offset by a decrease in the number of C Checks. Heavy Maintenance expense on 767 aircraft decreased $1.6 million primarily due to a decrease in the number of C Checks. Line Maintenance increased by $5.5 million on 767 aircraft, $3.9 million on 747-400 aircraft and $2.4 million on 747-8F aircraft due to increased flying. Heavy airframe maintenance checks and engine overhauls impacting Maintenance, materials and repairs for 2015 and 2014 were:

Heavy Maintenance Events	2015		2014		Inc/(Dec)

747-400 D Checks		4		6		(2)
767 C Checks		1		3		(2)
CF6-80 engine overhauls		10		14		(4)

Aircraft rent increased $4.6 million, or 3.3%, primarily due to a leased 747-400BCF aircraft that entered service in June 2015.

Depreciation and amortization increased $7.9 million, or 6.6%, primarily due to increased scrapping of rotable parts related to our engine and spare parts purchase program, which avoids more expensive repairs, and additional aircraft operating in 2015.

Travel increased $23.6 million, or 29.7%, primarily due to higher rates related to crewmember travel to higher cost locations and increased flying.

Navigation fees, landing fees and other rent decreased $31.8 million, or 24.2%, primarily due to a reduction in purchased capacity from the subcontracting of certain Charter flights.

Passenger and ground handling services decreased $3.6 million, or 4.2%, primarily due to lower rates related to ground handling for Charters, partially offset by increased flying.

Loss on disposal of aircraft in 2014 resulted from the trade-in of used spare engines for new engines as part of our engine acquisition program.

Special charge in 2015 primarily represents an $8.3 million impairment loss on engines held for sale and a $7.7 million charge for the early termination of high-rate operating leases for two engines. Special charge in 2014 represents a $6.2 million impairment loss on an aircraft held for sale, a $4.7 million loss related to a consolidated subsidiary’s receivable for a loan made to its then 51% U.K. shareholder and a $3.8 million expense recorded for termination benefits for certain employees (see Note 4 to our Financial Statements).

Other increased $118.0 million, or 101.6%, primarily due to the settlement of the U.S. class action litigation and related legal fees (see Note 14 to our Financial Statements), increased commission expense on higher revenue from the AMC and increased professional fees to support key initiatives.

Non-operating Expenses (Income)

The following table compares our Non-operating Expenses (Income) (in thousands):

	2015			2014			Inc/(Dec)			% Change
Non-operating Expenses (Income)
Interest income	$	(12,554	)	$	(18,480	)	$	(5,926	)		(32.1	)%

Capitalized interest		(1,027	)		(453	)		574			126.7	%
Loss on early extinguishment of debt		69,728			—			69,728			NM
Gain on investments		(13,439	)		—			13,439			NM
Other expense (income), net		1,261			1,104			157			14.2	%

Interest income decreased $5.9 million, or 32.1%, primarily due to a decrease in our investments in Pass-Through Trust Certificates (“PTCs”). See Note 12 to our Financial Statements for further discussion.

Interest expense decreased $7.5 million, or 7.2%, primarily due to a decrease in interest rates resulting from the refinancing of higher-rate enhanced equipment trust certificates (“EETCs”) with lower-rate Convertible Notes (see Note 9 to our Financial Statements for further discussion) and a reduction in our average debt balances, reflecting payments of debt.

Loss on early extinguishment of debt was related to the refinancing of five EETCs with lower-rate Convertible Notes and the refinancing of two 747-8F term loans during 2015. See Note 9 to our Financial Statements for further discussion.

Gain on investments was related to the early redemption of certain PTC investments resulting from the refinancing of five EETCs with lower-rate Convertible Notes during 2015. See Notes 9 and 12 to our Financial Statements for further discussion.

Income taxes. Our effective income tax rates were benefits of 142.3% for 2015 and 14.2% for 2014. The effective income tax rate for 2015 differed from the U.S. federal statutory rate primarily due to an increase in income from our Dry Leasing business taxed at lower rates and income tax benefits related ETI. The effective income tax rate for 2014 differed from the U.S. federal statutory rate primarily due to an income tax benefit of $34.8 million, net of reserves, related to ETI. The effective income tax rates for both periods benefit from our intention to indefinitely reinvest the net earnings of certain foreign subsidiaries outside the U.S.

Segments

The following table compares the Direct Contribution for our reportable segments (see Note 13 to our Financial Statements for the reconciliation to Operating income) (in thousands):

Unallocated income and expenses, net	$	294,451	$	161,616	$	132,835			82.2	%

43

ACMI Segment

ACMI Direct Contribution decreased $14.9 million, or 7.4%, primarily due to increases in crew costs due to crew training related to our investment in fleet growth, the impact of customers that flew below their contractual minimums in 2014 and payments received in 2014 related to a customer’s return of aircraft. Partially offsetting these decreases was a reduction in Heavy Maintenance expense and lower aircraft ownership costs from the refinancing of EETCs with lower-rate Convertible Notes.

Charter Segment

Charter Direct Contribution increased $77.6 million or 164.2%, primarily due to higher Yields, excluding fuel, increased cargo and passenger flying, as well as higher aircraft utilization, which was enhanced by the U.S. West Coast port disruption in early 2015. In addition, Charter Direct Contribution benefited from a reduction in Heavy Maintenance expense and lower aircraft ownership costs from the refinancing of EETCs with lower-rate Convertible Notes. Partially offsetting these improvements was an increase in crew costs due to crew training related to our investment in fleet growth.

Dry Leasing Segment

Dry Leasing Direct Contribution increased $8.8 million, or 26.5%, primarily due to revenue from maintenance payments related to the scheduled returns of a 737-800 passenger aircraft in February 2015 and a 757-200 cargo aircraft in April 2015, partially offset by a reduction in the number of Dry Leased aircraft following the sale of the returned 737-800 passenger aircraft during the first quarter of 2015.

Unallocated income and expenses, net

Unallocated income and expenses, net increased $132.8 million, or 82.2%, primarily due to the settlement of the U.S. class action litigation and related legal fees, increases in noncash expenses related to our Convertible Notes and the refinancing of debt and professional fees to support key initiatives.

Reconciliation of GAAP to non-GAAP Financial Measures

To supplement our Financial Statements presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”), we present certain non-GAAP financial measures to assist in the evaluation of our business performance. These non-GAAP financial measures include Adjusted Income from continuing operations, net of taxes and Adjusted Diluted EPS from continuing operations, which exclude certain noncash income and expenses, and items impacting year-over-year comparisons of our results. These non-GAAP financial measures may not be comparable to similarly titled measures used by other companies and should not be considered in isolation or as a substitute for Income from continuing operations, net of taxes and Diluted EPS from continuing operations, which are the most directly comparable measures of performance prepared in accordance with GAAP.

We use these non-GAAP financial measures in assessing the performance of our ongoing operations and in planning and forecasting future periods. We believe that these adjusted measures, when considered together with the corresponding GAAP financial measures and the reconciliations to those measures, provide meaningful supplemental information to assist investors and analysts in understanding our business results and assessing our prospects for future performance.

(a) Compensation costs resulting from a change in control under certain benefit plans related to the Amazon transaction (see Note 7 to our Financial Statements).

(b) Noncash expenses and income, net in 2016 primarily related to amortization of debt discount on the Convertible Notes (see Note 9 to our Financial Statements) and amortization of customer incentive related to the Amazon Warrant (see Note 7 to our Financial Statements). Noncash expenses and income, net in 2015 primarily related to amortization and accretion of debt, lease and investment discounts.

(c) Unrealized loss on financial instruments related to the Amazon Warrant (see Note 7 to our Financial Statements).

(d) Income tax effect of reconciling items is primarily impacted by a nondeductible customer incentive and nondeductible compensation expenses resulting from a change in control, as defined under certain of the Company’s benefit plans, both related to the Amazon transaction.

Liquidity and Capital Resources

The most significant liquidity events in 2016 were as follows:

Acquisition Transaction

In April 2016, we completed the acquisition of Southern Air for cash consideration of $105.4 million, net of cash acquired and working capital adjustments.

Debt Transactions

In February 2016, we borrowed $14.8 million related to the conversion of a 767-300BDSF aircraft under a term loan at a fixed interest rate of 3.19%.

In June 2016, we borrowed $70.0 million under a term loan secured by a mortgage against six spare GEnx engines at a fixed rate of 3.12%.

In December 2016, we borrowed $18.7 million related to GEnx engine performance upgrade kits and overhauls under an unsecured term loan at a fixed interest rate of 2.13%.

In December 2016, we entered into a $150.0 million revolving credit facility secured by mortgages against a total of 14 747-400 and 767-300 aircraft. As of December 31, 2016, no borrowings were outstanding under the facility. In January 2017, we drew down $100.0 million under the facility.

Operating Activities.    Net cash provided by operating activities for 2016 was $232.2 million, compared with $372.9 million for 2015. The decrease primarily reflects changes in the timing of working capital, a payment related to the U.S. class action settlement, payments for Transaction-related expenses and deferred maintenance costs for engines on 747-8F aircraft in 2016 and the impact of the U.S. West Coast port disruption in 2015. Partially offsetting these items were the impact of the Southern Air Acquisition and an increase in passenger and cargo demand from the AMC in 2016.

Investing Activities.    Net cash used for investing activities was $457.4 million for 2016, consisting primarily of $317.0 million of payments for flight equipment and modifications, $105.4 million related to the Southern Acquisition and $46.7 million of core capital expenditures, excluding flight equipment. Payments for flight equipment and modifications in 2016 were primarily related to the purchase of 767-300 passenger aircraft and related freighter conversion costs and spare engines. Partially offsetting these investing activities were $11.7 million of proceeds from investments. All capital expenditures for 2016 were funded through working capital, except for the flight equipment financed as discussed above. Net cash used for investing activities was $166.3 million for 2015, consisting primarily of $227.0 million of payments for flight equipment and modifications, and $45.0 million of core capital expenditures, excluding flight equipment. Payments for flight equipment and modifications in 2015

46

were primarily related to the purchase of a 747-8F aircraft, 767-300 passenger aircraft and related freighter conversion costs and spare engines. Partially offsetting these investing activities in 2015 were $80.3 million of proceeds from investments and $25.4 million of proceeds from disposal of aircraft.

Financing Activities.    Net cash used for financing activities was $75.5 million for 2016, which primarily reflected $179.2 million of payments on debt obligations, partially offset by $103.5 million of proceeds from debt issuance and $15.1 million of customer maintenance reserves received. Net cash used for financing activities was $80.5 million for 2015, which primarily reflected $568.9 million of payments on debt obligations, $52.9 million for the purchase of convertible note hedges, $36.1 million of payment of debt extinguishment costs, $26.5 million related to the purchase of treasury stock and $14.5 million of debt issuance costs partially offset by $568.0 million of proceeds from debt issuance, $36.3 million from the sale of warrants and $16.1 million of customer maintenance reserves received.

We consider Cash and cash equivalents, Short-term investments, Restricted cash and Net cash provided by operating activities to be sufficient to meet our debt and lease obligations, to fund core capital expenditures for 2017, and to pay amounts due related to the settlement of the U.S. class action litigation. Core capital expenditures for 2017 are expected to range between $55.0 to $65.0 million, which excludes flight equipment and capitalized interest. Our payments remaining for flight equipment purchase and conversion commitments are expected to be approximately $248.6 million, of which approximately $201.0 million is expected to be made during 2017. We expect to finance the acquisition and conversion of this flight equipment with our revolving credit facility prior to obtaining permanent financing for the converted aircraft.

We may access external sources of capital from time to time depending on our cash requirements, assessments of current and anticipated market conditions, and the after-tax cost of capital. To that end, we filed a shelf registration statement with the SEC in May 2015 that enables us to sell a yet to be determined amount of debt and/or equity securities over the subsequent three years, depending on market conditions, our capital needs and other factors. Our access to capital markets can be adversely impacted by prevailing economic conditions and by financial, business and other factors, some of which are beyond our control. Additionally, our borrowing costs are affected by market conditions and may be adversely impacted by a tightening in credit markets.

We do not expect to pay any significant U.S. federal income tax until 2025 or later. Our business operations are subject to income tax in several foreign jurisdictions. We do not expect to pay any significant cash income taxes in foreign jurisdictions for at least several years. We currently do not intend to repatriate cash from certain foreign subsidiaries that is indefinitely reinvested outside the U.S. Any repatriation of cash from these subsidiaries or certain changes in U.S. tax laws could result in additional tax expense.

Contractual Obligations

The table below provides details of our balances available under credit agreements and future cash contractual obligations as of December 31, 2016 (in millions):

(1) Debt reflects gross amounts (see Note 9 to our Financial Statements for a discussion of the related unamortized discount).

(2) Amount represents interest on fixed and floating rate debt at December 31, 2016.

(3) Amount represents estimated payments primarily related to 767-300 aircraft purchases and passenger-to-freighter conversions.

We maintain a noncurrent liability for unrecognized income tax benefits. To date, we have not resolved the ultimate cash settlement of this liability. As a result, we are not in a position to estimate with reasonable certainty the date upon which this liability would be payable.

Description of Our Debt Obligations

See Note 9 to our Financial Statements for a description of our debt obligations.

Off-Balance Sheet Arrangements

Fifteen of our sixty-one operating and Dry Leased aircraft are under operating leases (this excludes aircraft provided by CMI customers). Five are leased through trusts established specifically to purchase, finance and lease aircraft to us. These leasing entities meet the criteria for variable interest entities. All fixed price options reflect a fair market value purchase option, and as such, we are not the primary beneficiary of the leasing entities. We are generally not the primary beneficiary of the leasing entities if the lease terms are consistent with market terms at the inception of the lease and the leases do not include a residual value guarantee, fixed-price purchase option or similar feature that would obligate us to absorb decreases in value or entitle us to participate in increases in the value of the aircraft. We have not consolidated any of the aircraft-leasing trusts because we are not the primary beneficiary. In addition, we reviewed the other nine Atlas aircraft that are under operating leases but not financed through a trust and determined that none of them would be consolidated upon the application of accounting for consolidations. Our maximum exposure under all operating leases is the remaining lease payments, which amounts are reflected in the future lease commitments above and described in Note 10 to our Financial Statements.

There were no changes in our off-balance sheet arrangements during the fiscal year ended December 31, 2016.

Critical Accounting Policies and Estimates

General Discussion of Critical Accounting Policies and Estimates

An appreciation of our critical accounting policies and estimates is important to understand our financial results. Our Financial Statements are prepared in conformity with GAAP. Our critical policies require management to make estimates and judgments that affect the amounts reported. Actual results may differ significantly from those estimates. The following is a brief description of our current critical accounting policies involving significant management judgment:

Accounting for Long-Lived Assets

We record our property and equipment at cost, and once assets are placed in service, we depreciate them on a straight-line basis over their estimated useful lives to their estimated residual values over periods not to exceed forty years for flight equipment (from date of original manufacture) and three to five years for ground equipment.

We record finite-lived intangible assets acquired at fair value and amortize them over their estimated useful lives. The estimated useful lives are based on estimates of the period during which the assets are expected to generate revenue.

48

We record impairment charges on long-lived assets when events and circumstances indicate that the assets may be impaired, the undiscounted cash flows estimated to be generated by those assets are less than their carrying amount and the net book value of the assets exceeds their estimated fair value. In making these determinations, we use certain assumptions, including, but not limited to: (i) estimated fair value of the assets and (ii) estimated future cash flows expected to be generated by these assets, which are based on additional assumptions such as asset utilization, revenue generated, associated costs, length of service and estimated residual values. To conduct impairment testing, we group assets and liabilities at the lowest level for which identifiable cash flows are largely independent of cash flows of other assets and liabilities. For flight equipment used in our ACMI and Charter segments, assets are grouped at the operating fleet level. For flight equipment used in our Dry Leasing segment, assets are grouped on an individual basis.

For assets classified as held for sale, an impairment is recognized when the fair value less the cost to sell the asset is less than its carrying amount. Fair value is primarily determined using external appraisals.

In developing these estimates for flight equipment, we use industry data for the equipment types and our anticipated utilization of the assets.

Heavy Maintenance

Except for engines used on our 747-8F aircraft, we account for heavy maintenance costs for airframes and engines used in our ACMI and Charter segments using the direct expense method. Under this method, heavy maintenance costs are charged to expense upon induction, based on our best estimate of the costs. This method can result in expense volatility between quarterly and annual periods, depending on the number and type of heavy maintenance events performed.

We account for heavy maintenance costs for airframes and engines used in our Dry Leasing segment and engines used on our 747-8F aircraft using the deferral method. Under this method, we defer the expense recognition of scheduled heavy maintenance events, which are amortized over the estimated period until the next scheduled heavy maintenance event is required.

Income Taxes

Deferred income taxes are recognized for the tax consequences of reporting items in our income tax returns at different times than the items are reflected in our financial statements. These temporary differences result in deferred tax assets and liabilities that are calculated by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. If necessary, deferred income tax assets are reduced by a valuation allowance to an amount that is determined to be more likely than not recoverable. We must make significant estimates and assumptions about future taxable income and future tax consequences when determining the amount, if any, of the valuation allowance.

We have recorded reserves for income taxes that may become payable in future years. Although management believes that its positions taken on income tax matters are reasonable, we have nevertheless established tax reserves in recognition that various taxing authorities may challenge certain of the positions taken by us, potentially resulting in additional liabilities for taxes.

Goodwill

Goodwill represents the excess of an acquisition’s purchase price over the fair value of the identifiable net assets acquired and liabilities assumed. Goodwill is not amortized, but tested for impairment annually during the fourth quarter of each year, or more frequently if certain events or circumstances indicate that an impairment loss may have been incurred. We may elect to perform a qualitative analysis on the reporting unit that has goodwill to

49

determine whether it is more likely than not that fair value of the reporting unit is less than its carrying value. Under the qualitative approach, we consider various market factors to determine whether events and circumstances have affected the fair value of the reporting unit. If we determine that it is more likely than not that the reporting unit’s fair value is less than its carrying amount, or if we elect not to perform a qualitative analysis, we perform a quantitative analysis to determine whether any goodwill impairment exists.

Fair value is determined using a discounted cash flow analysis based on key assumptions including, but not limited to, (i) a projection of revenues, expenses and other cash flows; (ii) terminal period revenue growth and cash flows; and (iii) an assumed discount rate. If the goodwill’s carrying value exceeds its fair value calculated using the quantitative approach, an impairment charge is recorded for the difference in fair value and carrying value.

Legal and Regulatory Matters

We are party to legal and regulatory proceedings with respect to a variety of matters in multiple jurisdictions. We evaluate the likelihood of an unfavorable outcome of these proceedings each quarter. Our judgments are subjective and are based on the status of the legal or regulatory proceedings, the merits of our defenses and consultation with legal counsel.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We currently do not hedge against foreign currency fluctuations or aircraft fuel. The potential loss arising from adverse changes to the price and availability of aircraft fuel and interest rates is discussed below. The sensitivity analyses presented herein do not consider the effects that such adverse changes might have on our overall financial performance, nor do they consider additional actions we may take to mitigate our exposure to such changes.

Aircraft Fuel.    Our results of operations are affected by changes in the price and availability of aircraft fuel. We have limited fuel risk for our Charter business. Market risk is estimated at a hypothetical 20% increase or decrease in the 2016 average cost per gallon of fuel. Based on actual 2016 fuel consumption for commercial customers in Charter, such an increase would have resulted in an increase to aircraft fuel expense of approximately $28.1 million in 2016. For our AMC-related Charter flights, the contracted fuel prices are established and fixed by the AMC. We receive reimbursements from the AMC each month if the price of fuel paid by us to vendors for AMC-related Charter flights exceeds the fixed price; if the price of fuel paid by us is less than the fixed price, then we pay the difference to the AMC. ACMI and Dry Leasing do not create an aircraft fuel market risk, as the cost of fuel is borne by the customer.

Variable Interest Rates.    Our earnings are affected by changes in interest rates due to the impact those changes have on interest expense from variable rate debt instruments and on interest income generated from our cash and investment balances. As of December 31, 2016, approximately $91.0 million of our debt at face value had variable interest rates. If interest rates would have increased or decreased by a hypothetical 20% in the underlying rate as of December 31, 2016, our annual interest expense would have changed in 2016 by approximately $0.7 million.

Foreign Currency.    We have limited exposure to market risk from changes in foreign currency exchange rates, interest rates and equity prices that could affect our results of operations and financial condition. Our largest exposure comes from the Brazilian real.

50

Stock Price.    Our earnings are affected by changes in our common stock price due to the impact those changes have on the fair value of our liability for warrants issued to Amazon (See Note 7 to our Financial Statements for a description of the warrants). As of December 31, 2016, our warrant liability was $95.8 million. If our stock price would have increased or decreased resulting in a hypothetical 20% change in the fair value of the warrant liability as of December 31, 2016, we would have recognized an additional unrealized loss or gain of approximately $19.2 million in 2016.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of

Atlas Air Worldwide Holdings, Inc.

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of Atlas Air Worldwide Holdings, Inc. and its subsidiaries at December 31, 2016 and 2015, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2016 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Atlas Air Worldwide Holdings, Inc.

Notes to Consolidated Financial Statements

December 31, 2016

1.     Basis of Presentation

Our consolidated financial statements include the accounts of the holding company, Atlas Air Worldwide Holdings, Inc. (“AAWW”), and its consolidated subsidiaries. AAWW is the parent company of Atlas Air, Inc. (“Atlas”) and Southern Air Holdings, Inc. (“Southern Air”). Southern Air was acquired on April 7, 2016 (see Note 4). AAWW is also the parent company of several subsidiaries related to our dry leasing services (collectively referred to as “Titan”). AAWW has a 51% equity interest and 75% voting interest in Polar Air Cargo Worldwide, Inc. (“Polar”). We record our share of Polar’s results under the equity method of accounting.

Noncontrolling interests represents the interest not owned by us and is recorded for consolidated entities in which we own less than 100% of the interest. Intercompany accounts and transactions have been eliminated. We account for investments in entities under the equity method of accounting when we hold between 20% and 50% ownership in the entity and exercise significant influence or when we are not the primary beneficiary of a variable interest entity. The terms “we,” “us,” “our,” and the “Company” mean AAWW and all entities included in its consolidated financial statements.

We provide outsourced aircraft and aviation operating services throughout the world, serving Africa, Asia, Australia, Europe, the Middle East, North America and South America through: (i) contractual service arrangements, including those through which we provide aircraft to customers and value-added services, including crew, maintenance and insurance (“ACMI”), as well as those through which we provide crew, maintenance and insurance, but not the aircraft (“CMI”); (ii) cargo and passenger charter services (“Charter”); and (iii) dry leasing aircraft and engines (“Dry Leasing” or “Dry Lease”).

Except for per share data, all dollar amounts are in thousands unless otherwise noted.

2.     Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires us to make estimates and judgments that affect the amounts reported in these financial statements and the related disclosures. Actual results may differ from those estimates. Estimates are used in determining, among other items, asset lives and residual values, cash flows for impairment analysis, heavy maintenance costs, income tax accounting, business combinations, intangible assets, warrants, contingent liabilities (including, but not limited to litigation accruals), valuation allowances (including, but not limited to, those related to receivables, expendable parts inventory and deferred taxes), stock-based compensation and self-insurance employee benefit accruals.

Revenue Recognition

Revenue from ACMI and CMI contracts is typically recognized as the block hours are operated on behalf of a customer during a given month, as defined contractually, based on flight departure. The time interval between when an aircraft departs the terminal until it arrives at the destination terminal is measured in hours and called a “Block Hour”. If a customer flies below a minimum contracted Block Hour guarantee, the contracted minimum revenue amounts are recognized as revenue. We recognize revenue for Charter upon flight departure.

We record Dry Lease rental income on a straight-line basis over the term of the operating lease. In limited cases, leases provide for additional rentals based on usage, which is recorded as revenue as it is earned under the terms of the lease. Usage is calculated based on hourly usage or number of flights operated, depending on the lease agreement, and is typically reported monthly by the lessee. Rentals received but unearned under the lease agreements are recorded in deferred revenue and included in Accrued liabilities until earned.

59

Customer maintenance reserves are amounts received under our Dry Leases that are subject to reimbursement to the lessee upon the completion of qualifying maintenance work on the specific Dry Leased aircraft and are included in Accrued liabilities. We defer revenue recognition until the end of the lease, when we are able to finalize the amount, if any, to be reimbursed to the customer.

The Company recognizes revenue for management and administrative support services when the services are provided.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand, demand deposits and other cash investments that are highly liquid in nature and have original maturities of three months or less at acquisition.

Short-term Investments

Short-term investments are primarily comprised of certificates of deposit, current portions of debt securities and money market funds.

Restricted Cash

Cash that is restricted under secured aircraft debt agreements, whereby it can only be used to make principal and interest payments on the related debt secured by those aircraft, is classified as Restricted cash.

Accounts Receivable

We perform a monthly evaluation of our accounts receivable and establish an allowance for doubtful accounts based on our best estimate of probable credit losses resulting from the inability or unwillingness of our customers to make required payments. Account balances are charged off against the allowance when we determine that the receivable will not be recovered.

Escrow Deposits and Letters of Credit

We had $5.0 million as of December 31, 2016 and $3.9 million as of December 31, 2015, for certain deposits required in the normal course of business for various items including, but not limited to, surety and customs bonds, airfield privileges, judicial deposits, insurance and cash pledged under standby letters of credit related to collateral. These amounts are included in Deposits and other assets.

Expendable Parts

Expendable parts, materials and supplies for flight equipment are carried at average acquisition costs and are included in Prepaid expenses and other current assets. When used in operations, they are charged to maintenance expense. Allowances for excess and obsolescence for expendable parts expected to be on hand at the date aircraft are retired from service are provided over the estimated useful lives of the related airframes and engines. These allowances are based on management estimates, which are subject to change as conditions in the business evolve. The net book value of expendable parts inventory was $24.2 million as of December 31, 2016 and $18.1 million at December 31, 2015, net of allowances for obsolescence of $22.3 million at December 31, 2016 and $19.7 million at December 31, 2015.

Property and Equipment

We record property and equipment at cost and depreciate these assets to their estimated residual values on a straight-line basis over their estimated useful lives or average remaining fleet lives. We review these assumptions

60

at least annually and adjust depreciation on a prospective basis. Expenditures for major additions, improvements and flight equipment modifications are generally capitalized and depreciated over the shorter of the estimated life of the improvement, the modified assets’ remaining life or remaining lease term. Most of our flight equipment is specifically pledged as collateral for our indebtedness. The estimated useful lives of our property and equipment are as follows:

	Range
Flight equipment	3 to 40 years
Computer software and equipment	3 to 5 years
Ground handling equipment and other	3 to 5 years

Depreciation expense related to property and equipment was $141.5 million in 2016, $122.2 million in 2015 and $114.0 million in 2014.

The net book value of flight equipment on dry lease to customers was $936.0 million as of December 31, 2016 and $887.9 million as of December 31, 2015. The accumulated depreciation for flight equipment on dry lease to customers was $99.8 million as of December 31, 2016 and $64.5 million as of December 31, 2015.

Rotable parts are recorded in Property and equipment, net, and are depreciated over their average remaining fleet lives and written off when they are determined to be beyond economic repair. The net book value of rotable parts inventory was $142.7 million as of December 31, 2016 and $125.6 million as of December 31, 2015.

Capitalized Interest on Flight Equipment Modifications in Progress

Interest on funds used to finance the acquisition of flight equipment up to the date the asset is ready for its intended use is capitalized and included in the cost of the asset. Included in capitalized interest is the interest paid on the purchase deposit borrowings directly associated with the acquisition of flight equipment. The remainder of capitalized interest recorded on the acquisition of flight equipment is determined by taking the weighted average cost of funds associated with our other debt and applying it against the amounts paid as purchase deposits.

Goodwill

Goodwill represents the excess of an acquisition’s purchase price over the fair value of the identifiable net assets acquired and liabilities assumed. Goodwill is not amortized, but tested for impairment annually during the fourth quarter of each year, or more frequently if certain events or circumstances indicate that an impairment loss may have been incurred.

We may elect to perform a qualitative analysis on the reporting unit that has goodwill to determine whether it is more likely than not that fair value of the reporting unit is less than its carrying value. If the qualitative analysis indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if we elect not to perform a qualitative analysis, we perform a quantitative analysis to determine whether a goodwill impairment exists. If the goodwill’s carrying value exceeds its fair value calculated using the quantitative approach, an impairment charge is recorded for the difference in fair value and carrying value.

Fair value is determined using a discounted cash flow analysis based on key assumptions including, but not limited to, (i) a projection of revenues, expenses and other cash flows; (ii) terminal period revenue growth and cash flows; and (iii) an assumed discount rate.

The total amount of goodwill was $40.4 million, which is included in Intangible assets, net and goodwill, and Prepaid expense and other current assets in the consolidated balance sheets as of December 31, 2016 (see Notes 4 and 6). During the fourth quarter of 2016, we performed a quantitative analysis and determined that goodwill was not impaired.

61

Impairment of Long-Lived Assets

We record impairment charges on long-lived assets when events and circumstances indicate that the assets may be impaired, the undiscounted cash flows estimated to be generated by those assets are less than the associated carrying amount and the net book value of the assets exceeds the associated estimated fair value.

For flight equipment and finite-lived intangibles used in our ACMI and Charter segments, assets are grouped at the operating fleet level for impairment testing. For flight equipment and finite-lived intangibles used in our Dry Leasing segment, assets are tested on an individual basis for impairment.

For assets classified as held for sale, an impairment is recognized when the fair value less the cost to sell the asset is less than its carrying amount.

In developing estimates for flight equipment and cash flows, we use external appraisals and other industry data for the various equipment types, anticipated utilization of the assets, revenue generated, associated costs and length of service.

Long-term Investments

Long-term investments consist of debt securities, including accrued interest, for which management has the intent and ability to hold to maturity. These investments are classified as held-to-maturity and are reported at amortized cost. Interest on debt securities and accretion of discounts using the effective interest method are included in Interest income.

Variable Interest Entities and Off-Balance Sheet Arrangements

We hold a 50% interest in GATS GP (BVI) Ltd. (“GATS”), a joint venture with an unrelated third party. The purpose of the joint venture is to purchase rotable parts and provide repair services for those parts, primarily for our 747-8F aircraft. The joint venture is a variable interest entity and we have not consolidated GATS because we are not the primary beneficiary as we do not exercise financial control. Our investment in GATS was $22.2 million as of December 31, 2016 and $20.7 million as of December 31, 2015 and our maximum exposure to losses from the entity is limited to our investment, which is composed primarily of rotable inventory parts. GATS does not have any third-party debt obligations. We had Accounts payable to GATS of $2.4 million as of December 31, 2016 and $2.3 million as of December 31, 2015.

A portion of our operating aircraft are owned or effectively owned and leased through trusts established specifically to purchase, finance and lease aircraft to us. We have not consolidated any aircraft in the related trusts because we are not the primary beneficiary. Our maximum exposure under these operating leases is the remaining lease payments, which amounts are reflected in the future lease commitments more fully described in Note 10.

Income Taxes

Deferred income taxes are recognized for the tax consequences of reporting items in our income tax returns at different times than the items are reflected in our financial statements. These temporary differences result in deferred tax assets and liabilities that are calculated by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. If necessary, deferred income tax assets are reduced by a valuation allowance to an amount that is determined to be more likely than not recoverable. We must make significant estimates and assumptions about future taxable income and future tax consequences when determining the amount, if any, of the valuation allowance.

62

We have recorded reserves for income taxes that may become payable in future years. Although management believes that its positions taken on income tax matters are reasonable, we have nevertheless established tax reserves in recognition that various taxing authorities may challenge certain of the positions taken by us, potentially resulting in additional liabilities for taxes.

Heavy Maintenance

Except for engines used on our 747-8F aircraft, we account for heavy maintenance costs for airframes and engines used in our ACMI and Charter segments using the direct expense method. Under this method, heavy maintenance costs are charged to expense upon induction, based on our best estimate of the costs.

We account for heavy maintenance costs for airframes and engines used in our Dry Leasing segment and engines used on our 747-8F aircraft using the deferral method. Under this method, we defer the expense recognition of scheduled heavy maintenance events, which are amortized over the estimated period until the next scheduled heavy maintenance event is required. As of December 31, 2016 and December 31, 2015, deferred maintenance, net was $19.1 million and zero, respectively, which was included within Deferred costs and other assets. During 2016, we deferred maintenance costs of $19.6 million and recorded deferred maintenance amortization expense of $0.5 million included in depreciation and amortization expense.

Prepaid Maintenance Deposits

Certain of our aircraft financing agreements require security deposits to our finance providers to ensure that we perform major maintenance as required. These are substantially refundable to us and are, therefore, accounted for as deposits and included in Prepaid maintenance and in Deferred costs and other assets. Such amounts were $53.4 million as of December 31, 2016 and $47.2 million at December 31, 2015.

Foreign Currency

While most of our revenues are denominated in U.S. dollars, our results of operations may be exposed to the effect of fluctuations in the U.S. dollar value of foreign currency-denominated operating revenues and expenses. Our largest exposures come from the Brazilian real. We do not currently have a foreign currency hedging program related to our foreign currency-denominated transactions. Gains or losses resulting from foreign currency transactions are included within Non-operating expenses (income).

Stock-Based Compensation

We have various stock-based compensation plans for certain employees and outside directors, which are described more fully in Note 15. We recognize compensation expense, net of estimated forfeitures, on a straight-line basis over the vesting period for each award based on the fair value on grant date. We estimate grant date fair value for all option grants using the Black-Scholes-Merton option pricing model. We estimate option and restricted stock unit forfeitures at the time of grant and periodically revise those estimates in subsequent periods if actual forfeitures differ from those estimates. As a result, we record stock-based compensation expense only for those awards that are expected to vest.

Legal and Regulatory Matters

We are party to legal and regulatory proceedings with respect to a variety of matters. We evaluate the likelihood of an unfavorable outcome of these proceedings each quarter. Our judgments are subjective and are based on the status of the legal or regulatory proceedings, the merits of our defenses and consultation with legal counsel. Due to the inherent uncertainties of the legal and regulatory proceedings in the multiple jurisdictions in which we operate, our judgments may be different from the actual outcomes.

63

Supplemental Cash Flow Information

Cash interest paid to lenders is calculated on the face amount of our various debt instruments based on the contractual interest rates in effect during each payment period.

The following table summarizes interest and income taxes paid:

	2016		2015			2014
Interest paid	$	66,306	$	75,135		$	84,265
Income taxes paid, net of refunds	$	1,160	$	(228	)	$	1,181

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balance sheets that sum to the total of the same such amounts shown in the consolidated statements of cash flows:

	2016		2015
Cash and cash equivalents	$	123,890	$	425,950
Restricted cash		14,360		12,981
Total cash, cash equivalents and restricted cash shown in consolidated statements of cash flows	$	138,250	$	438,931

Recent Accounting Pronouncements

In November 2016, the Financial Accounting Standards Board (“FASB”) amended its accounting guidance for statements of cash flows. Under the amended guidance, restricted cash should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period amounts shown on the statement of cash flows. We early adopted this guidance retrospectively effective December 31, 2016 and its adoption did not have a material impact on our financial condition, results of operations or cash flows. The amount of restricted cash reclassified to the end-of-period amounts in our statement of cash flows were $13.0 million and $14.3 million as of December 31, 2015 and 2014, respectively. As a result, net cash used for investing activities increased by $1.3 million and decreased by $7.8 million for the years ended December 31, 2015 and 2014, respectively.

In March 2016, the FASB amended its accounting guidance for share-based compensation. The amended guidance changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. This amended guidance is effective as of the beginning of 2017, with early adoption permitted. We adopted this guidance on January 1, 2017. Upon adoption of this amended guidance, the excess tax benefit associated with share-based compensation, which is currently recognized within equity, will be reflected within income tax expense (benefit) in our consolidated statements of operations. Additionally, our consolidated statements of cash flows will present such excess tax benefit, which is currently presented as a financing activity, as an operating activity. The adoption of this amended guidance is not expected to have a material impact on our financial condition, results of operations or cash flows.

In February 2016, the FASB amended its accounting guidance for leases. The guidance requires a lessee to recognize assets and liabilities on the balance sheet arising from leases with terms greater than twelve months. While lessor accounting guidance is relatively unchanged, certain amendments were made to conform with changes made to lessee accounting and recently released revenue recognition guidance. The new guidance will continue to classify leases as either finance or operating, with classification affecting the pattern of expense and income recognition in the statement of operations. It also requires additional quantitative and qualitative disclosures about leasing arrangements. The amended guidance is effective as of the beginning of 2019, with early adoption permitted. While we are still assessing the impact the amended guidance will have on our

64

financial statements, we expect that recognizing the right-of-use asset and related lease liability will significantly impact our balance sheet. We have developed and are implementing a plan for adopting this amended guidance.

In May 2014, the FASB amended its accounting guidance for revenue recognition. Subsequently, the FASB has issued several clarifications and updates. The fundamental principles of the new guidance are that companies should recognize revenue in a manner that reflects the timing of the transfer of services to customers and consideration that a company expects to receive for the services provided. It also requires additional disclosures necessary for the financial statement users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB deferred the effective date by one year to the beginning of 2018, with early adoption permitted. We plan to adopt this guidance on its required effective date. While we are still assessing the methods of adoption and impact the amended guidance will have on our financial statements, we expect that an immaterial amount of revenue currently recognized based on flight departure will likely be recognized over time as the services are performed. In addition, we expect that revenue related to contracted minimum block hour guarantees under certain ACMI and CMI contracts will likely be recognized in later periods under the amended guidance. We have developed and are implementing a plan for adopting this amended guidance.

3.     DHL Investment and Polar

DHL Network Operations (USA), Inc. (“DHL”), a subsidiary of Deutsche Post AG (“DP”), holds a 49% equity interest and a 25% voting interest in Polar. Polar is a variable interest entity and we do not consolidate Polar because we are not the primary beneficiary as the risks associated with the direct costs of operation are with DHL. Under a 20-year blocked space agreement, which began in 2008 (the “BSA”), Polar provides air cargo capacity to DHL. Atlas and Polar also have a flight services agreement, whereby Atlas is compensated by Polar on a per Block Hour basis, subject to a monthly minimum Block Hour guarantee, at a predetermined rate with the opportunity for performance premiums that escalate annually. Under the flight services agreement, Atlas provides Polar with crew, maintenance and insurance for the aircraft. Under other separate agreements, we provide aircraft to Polar, and Atlas and Polar supply administrative, sales and ground support services to one another. DP has guaranteed DHL’s (and Polar’s) obligations under the various transaction agreements described above. AAWW has agreed to indemnify DHL for and against various obligations of Polar and its affiliates. Collectively, these agreements are referred to herein as the “DHL Agreements”. The DHL Agreements provide us with a minimum guaranteed revenue stream from aircraft that have been dedicated to Polar for DHL and other customers’ freight over the life of the agreements. DHL provides financial support and also assumes the risks and rewards of the operations of Polar.

In accordance with the DHL Agreements, Polar flies for DHL’s transpacific express network and DHL provides financial support and assumes the risks and rewards of the operations of Polar. In addition to transpacific routes, Polar also flies between the Asia Pacific region, the Middle East and Europe on behalf of DHL and other customers.

The BSA established DHL’s capacity purchase commitments on Polar flights. DHL has the right to terminate the 20-year BSA at the twelfth and fifteenth anniversaries of commencement, which was October 27, 2008. Either party may terminate for cause (as defined) at any time. With respect to DHL, “cause” includes Polar’s inability to meet certain departure and arrival criteria for an extended period of time and upon certain change-of-control events, in which case DHL may be entitled to liquidated damages from Polar. Except for any liquidated damages that we could incur as described above, we do not have any continuing financial exposure to fund debt obligations or operating losses of Polar.

Combined with Polar, we provide ACMI, CMI, Charter and Dry Leasing services to support DHL’s transpacific express, North American and intra-Asian networks. In addition, we fly between the Asia Pacific region, the Middle East and Europe on behalf of DHL and other customers. Atlas also provides incremental charter capacity to Polar and DHL on an ad hoc basis.

4.     Southern Air Acquisition

On January 15, 2016, we entered into an Agreement and Plan of Merger to acquire all the outstanding shares of Southern Air (the “Southern Air Acquisition”). Southern Air is the parent company of several subsidiaries, including Southern Air Inc. and Florida West International Airways, Inc. (“Florida West”). The Southern Air Acquisition provided us with immediate entry into 777 and 737 aircraft operating platforms, with the potential for developing additional business with existing and new customers of both companies. We believe the platforms provided by these aircraft will augment our ability to offer customers the broadest array of aircraft and operating services for domestic, regional and international applications. Southern Air currently flies five 777-200LRF and five 737-400F aircraft under CMI agreements for DHL.

The Southern Air Acquisition was completed on April 7, 2016. Total consideration of $105.8 million, net of cash acquired, consisted of the following:

Fair value of consideration
Cash paid, net of $15,615 cash acquired	$	107,498
Working capital adjustment		(2,106	)
Other adjustments		372
Total consideration	$	105,764

66

Tangible and identifiable intangible assets acquired and liabilities assumed were recorded at fair value as of the acquisition date. During 2016, we made certain measurement-period adjustments, including the finalization of the fair value of Florida West, and working capital and other adjustments that resulted in a net increase to goodwill of $4.0 million.

The following table summarizes the preliminary amounts recognized for fair values of the assets acquired and liabilities assumed:

	Estimated Fair Value
Accounts receivable, net	$	22,912
Prepaid expenses and other current assets		2,434
Property and equipment		6,355
Intangible assets and goodwill		67,341
Deferred income taxes, net		36,452
Other assets		1,498
Total assets acquired	$	136,992
Accounts payable and accrued liabilities	$	31,228
Total liabilities assumed		31,228
Net assets acquired	$	105,764

The fair values and useful lives assigned to all intangible assets and goodwill are as follows:

	Estimated Useful Lives		Estimated Fair Value
Customer relationship		16 years	$	26,280
Trade name		1.5 years		700
Goodwill		Indefinite		40,361
Total intangible assets and goodwill			$	67,341

Customer relationship represents the underlying relationship and agreements with DHL. The trade name relates to the Southern Air brand. Goodwill is not deductible for tax purposes and is primarily attributable to the expanded market opportunities expected from combining the service offerings of Southern Air with ours, as well as the employee work force acquired. Southern Air’s results of operations and goodwill are reflected in our ACMI segment. Amortization expense related to Southern Air’s intangible assets amounted to $1.6 million in 2016.

For 2016, our consolidated results include Southern Air’s operating revenue of $79.8 million. For 2016, we incurred Transaction-related expenses of $17.7 million, primarily related to: certain compensation costs, including employee termination benefits; professional fees; and integration costs associated with the acquisition.

A summary of the employee termination benefit liability, which is expected to be paid by the first quarter of 2018, is as follows:

	Employee Termination Benefits
Transaction-related expenses	$	3,797
Cash payments		(2,583	)
Liability as of December 31, 2016	$	1,214

67

The unaudited pro forma operating revenue for 2016 and 2015 was $1,866.7 million and $1,912.4 million, respectively. This pro forma information has been calculated as if the acquisition had taken place on January 1, 2015 and is not necessarily indicative of the net sales that actually would have been achieved. This information includes adjustments to conform with our accounting policies. The earnings of Southern Air were not material and, accordingly, pro forma and actual earnings information have not been presented.

As part of integrating Southern Air, management decided and committed to pursue a plan to sell Florida West. As a result, the financial results for Florida West are presented as a discontinued operation and the assets and liabilities of Florida West are classified as held for sale, since the date of acquisition through December 31, 2016. The aggregate carrying value of Florida West’s assets held for sale was insignificant at December 31, 2016 and was included in Prepaid expenses and other current assets. In February 2017, management determined that a sale was no longer likely to occur and committed to a plan to wind down the Florida West operations. The wind-down of operations is expected to be completed during the first quarter of 2017.

5.     Special Charge

During 2016 and 2015, we recognized $10.1 million of impairment losses for six CF6-80 engines classified as held for sale and $8.3 million for five CF6-80 engines classified as held for sale, respectively. Depreciation ceased on the engines. Nine engines were traded in during 2016. The carrying value of two CF6-80 engines held for sale at December 31, 2016 was $2.8 million and five CF6-80 engines held for sale at December 31, 2015 was $7.7 million, which were included within Prepaid expenses and other current assets in the consolidated balance sheets. Two remaining CF6-80 engines classified as held for sale are expected to be sold during 2017.

During 2015, we recognized a charge of $7.7 million related to the early termination of high-rate operating leases for two CF6-80 engines.

6.     Intangible Assets, Net and Goodwill

The following table presents our Intangible assets, net and goodwill as of December 31:

	2016			2015
Goodwill	$	40,361		$	—
Fair value adjustments on operating leases		45,531			45,531
Lease intangible		57,203			57,203
Customer relationship		26,280			—
Trade name		700			—
Less: accumulated amortization		(54,046	)		(44,251	)
	$	116,029		$	58,483

Goodwill is primarily attributable to the expanded market opportunities expected from combining the service offerings of Southern Air with ours, as well as the employee work force acquired. Fair value adjustments on operating leases represent the capitalized discount recorded in prior years to adjust the lease commitments for our 747-400 aircraft to fair market value and are amortized on a straight-line basis over the life of the leases. Lease intangibles resulted from the acquisition of various aircraft with in-place Dry Leases to customers on a long-term basis and are amortized on a straight-line basis over the life of the leases. Customer relationship represents Southern Air’s underlying relationship and agreements with DHL. The trade name relates to the Southern Air brand.

Amortization expense related to intangible assets amounted to $9.8 million in 2016, $8.9 million in 2015 and $9.4 million in 2014.

68

The estimated future amortization expense of intangible assets as of December 31, 2016 is as follows:

2017	$	9,914

7.     Amazon

In May 2016, we entered into certain agreements with Amazon.com, Inc. and its subsidiary, Amazon Fulfillment Services, Inc., (collectively “Amazon”), which will involve, among other things, CMI operation of 20 Boeing 767-300 freighter aircraft for Amazon by Atlas, as well as Dry Leasing by Titan. The Dry Leases will have a term of ten years, while the CMI operations will be for seven years (with an option for Amazon to extend the term to a total of ten years). The first aircraft was placed in service during the third quarter of 2016 and the remainder are expected to be placed in service by the end of 2018.

In conjunction with these agreements, 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 $37.50 per share. A portion of the warrant, representing the right to purchase 3.75 million shares, vested immediately upon issuance of the warrant and the remainder of the warrant, representing the right to purchase 3.75 million shares, will vest in increments of 375,000 as the lease and operation of each of the 11^th through 20^th aircraft commences. The warrant will be exercisable in accordance with its terms through 2021. As of December 31, 2016, no warrants have been exercised.

The agreements also provide 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 $37.50 per share. This warrant to purchase 3.75 million shares will vest in conjunction with payments by Amazon for additional business with us. The warrant will be exercisable in accordance with its terms through 2023.

At a special meeting on September 20, 2016, the Company’s shareholders, by a vote of approximately 99.9% of the votes cast, approved the issuance of warrants to acquire up to 30% of our outstanding common shares. This approval constituted a change in control, as defined under certain of the Company’s benefit plans. As a result, we recognized $23.5 million in expense, including accelerated compensation expense for restricted and performance share and cash awards, during 2016 (see Notes 15 and 16). The share-based portion of the compensation expense was $13.3 million.

The $92.9 million fair value of the vested portion of the warrant issued to Amazon as of May 4, 2016 was recorded as a warrant liability within Financial instruments and other liabilities (the “Amazon Warrant”). The initial fair value of the warrant was recognized as a customer incentive asset within Deferred costs and other assets, net and is being amortized as a reduction of revenue in proportion to the amount of revenue recognized over the terms of the Dry Leases and CMI agreements. During 2016, we amortized $0.5 million of the customer incentive asset. The balance of the customer incentive asset, net of amortization, was $92.4 million as of December 31, 2016.

The Amazon Warrant liability is marked-to-market at the end of each reporting period with changes in fair value recorded in Other non-operating expenses. We utilize a Monte Carlo simulation approach to estimate the

69

fair value of the Amazon Warrant which requires inputs such as our common stock price, the warrant strike price, estimated common stock price volatility and risk-free interest rate, among others. We recognized a net unrealized loss of $2.9 million on the Amazon Warrant during 2016. The fair value of the Amazon Warrant liability was $95.8 million as of December 31, 2016.

Many of our financing instruments have cross-default provisions and contain limitations on our ability to, among other things, consummate certain asset sales, merge or consolidate with any other person or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of our assets.

Description of our Debt Obligations

Ex-Im Bank Guaranteed Notes

We have issued various notes guaranteed by the Export-Import Bank of the United States (“Ex-Im Bank”), each secured by a mortgage on a 747-8F or 777-200LRF aircraft (the “Ex-Im Guaranteed Notes”). In connection with the issuance of Ex-Im Guaranteed Notes, we paid usual and customary commitment and other fees associated with this type of financing. In addition, there are customary covenants, events of default and certain operating conditions that we must meet for the Ex-Im Guaranteed Notes. These notes accrue interest at a fixed rate with principal and interest payable quarterly.

70

The following table summarizes the terms and principal balances for each note guaranteed by Ex-Im Bank as of December 31 (in millions):

Term Loans and Capital Lease

We have entered into various term loans to finance the acquisition of aircraft. Each term loan requires payment of principal and interest quarterly in arrears. Funds available under each term loan agreement are subject to usual and customary fees, and funds drawn under the loan agreements typically bear interest at a fixed rate based on LIBOR, plus a margin. Each facility is guaranteed by us and subject to customary covenants and events of default.

In February 2016, we borrowed $14.8 million related to the purchase and conversion of a 767-300BDSF aircraft under an eight-year term loan with a final payment of $3.8 million due in February 2024 (the “First 2016 Term Loan”) secured by a mortgage against the aircraft.

In June 2016, we borrowed $70.0 million under a five-year term loan with a final payment of $30.2 million due in June 2021 (the “Second 2016 Term Loan”). The Second 2016 Term Loan is secured by a mortgage against six spare GEnx engines.

In September 2016, we entered into a capital lease, with an option and the intention to purchase, for a 767-300 passenger aircraft which expires in February 2017.

In December 2016, we borrowed $18.7 million under an unsecured five-year term loan due in October 2021 (the “Third 2016 Term Loan”) for GEnx engine performance upgrade kits and overhauls.

In October 2015, we refinanced two higher-rate term loans, in the aggregate amount of $195.2 million, with a new lower-rate term loan (the “First 2015 Term Loan”) secured by a mortgage against two 747-8F aircraft.

In November 2015, we borrowed $125.0 million under a term loan (the “Second 2015 Term Loan”) secured by a mortgage against a 747-8F aircraft. The Second 2015 Term Loan is cross-collateralized and cross-defaulted with the First 2015 Term Loan.

In December 2015, we borrowed $23.3 million related to the purchase and conversion of a 767-300BDSF aircraft under a term loan (the “Third 2015 Term Loan”) secured by a mortgage against the aircraft.

Convertible Notes

In June 2015, we issued $224.5 million aggregate principal amount of convertible senior notes (the “Convertible Notes”) in an underwritten public offering. The Convertible Notes are senior unsecured obligations and accrue interest payable semiannually on June 1 and December 1 of each year at a fixed rate of 2.25%. The Convertible Notes will mature on June 1, 2022, unless earlier converted or repurchased pursuant to their terms.

During 2015, we used proceeds from the issuance of the Convertible Notes to refinance higher-rate equipment notes funded by enhanced equipment trust certificates (“EETCs”) related to five 747-400 freighter aircraft owned by us in the aggregate amount of $187.8 million. The EETCs had an average cash coupon of 8.1%. In connection with the refinancing, we recognized a $66.7 million loss on early extinguishment of debt, of which $34.0 million was related to debt extinguishment costs paid to the EETC equipment note holders and $32.7 million was related to the write-off of the debt discount associated with the EETCs. The debt extinguishment costs paid are reflected as a financing activity in the consolidated statements of cash flows. As a result of this refinancing, we recognized a $13.4 million Gain on investments from the early redemption of certain investments related to EETCs in 2015 (see Note 12).

72

Each $1,000 of principal of the Convertible Notes will initially be convertible into 13.5036 shares of our common stock, which is equal to an initial conversion price of $74.05 per share. The conversion rate will be subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid interest, except in certain limited circumstances. Upon the occurrence of a “make-whole fundamental change,” we will, in certain circumstances, increase the conversion rate by a number of additional shares of our common stock for Convertible Notes converted in connection with such “make-whole fundamental change”. Additionally, if we undergo a “fundamental change,” a holder will have the option to require us to repurchase all or a portion of its Convertible Notes for cash at a price equal to 100% of the principal amount of the Convertible Notes being repurchased plus any accrued and unpaid interest through, but excluding, the fundamental change repurchase date.

In connection with the offering of the Convertible Notes, we entered into convertible note hedge transactions whereby we have the option to purchase initially (subject to adjustment for certain specified events) a total of 3,031,558 shares of our common stock at a price of $74.05 per share. The total cost of the convertible note hedge transactions was $52.9 million. In addition, we sold warrants to the option counterparties whereby the holders of the warrants have the option to purchase initially (subject to adjustment for certain specified events) a total of 3,031,558 shares of our common stock at a price of $95.01. We received $36.3 million in cash proceeds from the sale of these warrants in 2015.

Taken together, the purchase of the convertible note hedges and the sale of warrants are intended to offset any economic dilution from the conversion of the Convertible Notes when the stock price is below $95.01 per share and to effectively increase the overall conversion price from $74.05 to $95.01 per share. However, for purposes of the computation of diluted earnings per share in accordance with GAAP, dilution will occur when the average share price of our common stock for a given period exceeds the conversion price of the Convertible Notes, which initially is equal to $74.05 per share. The $16.6 million net cost incurred in connection with the convertible note hedges and warrants was recorded as a reduction to additional paid-in capital, net of tax, in the consolidated balance sheet.

On or after September 1, 2021 until the close of business on the second scheduled trading day immediately preceding the maturity date, a holder may convert all or a portion of its Convertible Notes.

Upon conversion, the Convertible Notes will be settled, at our election, in cash, shares of our common stock, or a combination of cash and shares of our common stock. Our current intent and policy is to settle conversions with a combination of cash and shares of common stock with the principal amount of the Convertible Notes paid in cash.

Holders may convert their Convertible Notes at their option at any time prior to September 1, 2021, only under the following circumstances:

• during any calendar quarter (and only during such calendar quarter) if, for each of at least 20 trading days (whether or not consecutive) during the 30 consecutive trading day period ending on, and including, the last trading day of the immediately preceding calendar quarter, the last reported sale price of our common stock for such trading day is equal to or greater than 130% of the conversion price on such trading day;

• during the five consecutive business day period immediately following any five consecutive trading day period (the “measurement period”) in which, for each trading day of the measurement period, the trading price per $1,000 principal amount of the Convertible Notes for such trading day was less than 98% of the product of the last reported sale price of our common stock for such trading day and the conversion rate on such trading day; or

• upon the occurrence of specified corporate events.

We separately account for the liability and equity components of the Convertible Notes. The carrying amount of the liability component was determined by measuring the fair value of a similar liability that does not

73

have an associated conversion feature, assuming our nonconvertible unsecured debt borrowing rate. The carrying value of the equity component, the conversion option, which is recognized as additional paid-in-capital, net of tax, creates a debt discount on the Convertible Notes. The debt discount was determined by deducting the relative fair value of the liability component from the proceeds of the Convertible Notes and is amortized to interest expense using an effective interest rate of 6.44% over the term of the Convertible Notes. As of December 31, 2016, the remaining life of the Convertible Notes is 5.4 years. The equity component will not be remeasured as long as it continues to meet the conditions for equity classification.

The Convertible Notes consisted of the following as of December 31:

	2016			2015
Liability component:
Gross proceeds	$	224,500		$	224,500
Less: debt discount, net of amortization		(42,956	)		(49,377	)
Less: debt issuance cost, net of amortization		(4,146	)		(4,823	)
Net carrying amount	$	177,398		$	170,300
Equity component (1)	$	52,903		$	52,903

(1) Included in Additional paid-in capital on the consolidated balance sheet as of December 31, 2016 and 2015.

The debt issuance costs related to the issuance of the Convertible Notes were allocated to the liability and equity components based on their relative values, as determined above. Total debt issuance costs were $6.8 million, of which $5.2 million was allocated to the liability component and $1.6 million was allocated to the equity component. The debt issuance costs allocated to the liability component are amortized to interest expense using the effective interest method over the term of the Convertible Notes.

The following table presents the amount of interest expense recognized related to the Convertible Notes:

	For the Years Ended
	December 31, 2016		December 31, 2015
Contractual interest coupon	$	5,051	$	2,919
Amortization of debt discount		6,421		3,526
Amortization of debt issuance costs		677		380
Total interest expense recognized	$	12,149	$	6,825

EETC

In 1999, we issued an EETC secured by a 747-400F aircraft in the amount of $109.9 million for an original term of 20 years with interest rates on the underlying equipment notes ranging from 6.88% to 8.77% and an effective interest rate of 7.52%. The balance outstanding on the leveraged lease was $20.0 million and $28.0 million as of December 31, 2016 and 2015, respectively.

Revolving Credit Facility

In December 2016, we entered into a three-year $150.0 million secured revolving credit facility (the “Revolver”) for general corporate purposes, including financing the acquisition and conversion of 767 aircraft prior to obtaining permanent financing for the converted aircraft. The Revolver is secured by mortgages against nine 747-400 and five 767-300 aircraft, and related engines. Amounts outstanding under the Revolver are subject to borrowing base calculations, collateral coverage and fixed charge ratios. The Revolver accrues interest monthly at LIBOR plus a margin of 2.25% per annum on the amounts outstanding and 0.4% on the undrawn

74

portion. In connection with entry into the Revolver, we paid usual and customary fees. There were no amounts outstanding and we had $150.0 million of unused availability under the Revolver as of December 31, 2016. In January 2017, we drew down $100.0 million under the Revolver.

Future Cash Payments for Debt and Capital Lease

Leveraged Lease Structure

In three separate transactions in 1998, 1999 and 2000, we issued EETCs to finance the acquisition of five 747-400F aircraft as leveraged leases. In a leveraged lease, the owner trustee is the owner of record for the aircraft. Wells Fargo Bank Northwest, National Association (“Wells Fargo”) serves as the owner trustee with respect to the leveraged leases in each of our EETC transactions. As the owner trustee of the aircraft, Wells Fargo serves as the lessor of the aircraft under the EETC lease between us and the owner trustee. Wells Fargo also serves as trustee for the beneficial owner of the aircraft, the owner participant. The original owner participant for each aircraft invested (on an equity basis) approximately 20% of the original cost of the aircraft. The remaining approximately 80% of the aircraft cost was financed with debt issued by the owner trustee on a nonrecourse basis in the form of equipment notes.

The equipment notes were generally issued in three series, for each aircraft, designated as Series A, B and C equipment notes. The loans evidenced by the equipment notes were funded by the public offering of EETCs. Like the equipment notes, the EETCs were issued in three series, for each EETC transaction designated as Series A, B and C EETCs. Each series of EETCs was issued by the trustee for separate Atlas pass-through trusts with the same designation as the series of EETCs issued (PTCs”). Each of these pass-through trustees is also the holder and beneficial owner of the equipment notes bearing the same series designation.

These leasing entities meet the criteria for variable interest entities. We have not consolidated any of the aircraft-leasing trusts because we are not the primary beneficiary. We account for these leases as operating leases and have included them in our minimum annual rental commitments below.

Operating Leases

The following table summarizes rental expenses in:

	2016		2015		2014
Aircraft and engines	$	146,110	$	145,031	$	140,390
Purchased capacity, office, vehicles and other	$	23,727	$	44,228	$	68,855

75

As of December 31, 2016, fifteen of our sixty-one operating aircraft were leased, all, except for one, of which were operating leases, with initial lease term expiration dates ranging from 2017 to 2025, with an average remaining lease term of 5.7 years. Certain of our operating leases contain renewal options and escalations. In addition, we lease engines under short-term lease agreements on an as-needed basis. We record rent expense on a straight-line basis over the lease term.

The following table summarizes our minimum annual rental commitments as of the periods indicated under non-cancelable aircraft, engine, real estate and other operating leases with initial or remaining terms of more than one year, reflecting the terms that were in effect as of December 31, 2016:

	Aircraft and Engine Operating Leases		Other Operating Leases		Total

Equipment Purchase Commitments

As of December 31, 2016, our estimated payments remaining for flight equipment purchase commitments are $248.6 million, of which $201.0 million are expected to be made during 2017.

Guarantees and Indemnifications

In the ordinary course of business, we enter into numerous leasing and financing arrangements for real estate, equipment, aircraft and engines that have various guarantees included in the contracts. These guarantees are primarily in the form of indemnities. In both leasing and financing transactions, we typically indemnify the lessors and any financing parties against tort liabilities that arise out of the use, occupancy, manufacture, design, operation or maintenance of the leased premises or financed aircraft, regardless of whether these liabilities relate to the negligence of the indemnified parties. Currently, we believe that any future payments required under many of these guarantees or indemnities would be immaterial, as most tort liabilities and related indemnities are covered by insurance (subject to deductibles). However, payments under certain tax indemnities related to certain

76

of our financing arrangements, if applicable, could be material, and would not be covered by insurance, although we believe that these payments are not probable. Certain leased premises, such as maintenance and storage facilities, typically include indemnities of such parties for any environmental liability that may arise out of or relate to the use of the leased premises. We also provide standard indemnification agreements to officers and directors in the ordinary course of business.

Financings and Guarantees

Our financing arrangements typically contain a withholding tax provision that requires us to pay additional amounts to the applicable lender or other financing party, if withholding taxes are imposed on such lender or other financing party as a result of a change in the applicable tax law.

These increased costs and withholding tax provisions continue for the entire term of the applicable transaction and there is no limitation on the maximum additional amount we could be required to pay under such provisions. Any failure to pay amounts due under such provisions generally would trigger an event of default and, in a secured financing transaction, would entitle the lender to foreclose upon the collateral to realize the amount due.

11.    Income Taxes

The significant components of the provision for income taxes are as follows:

	2016			2015			2014
Current:
Federal	$	(376	)	$	52		$	607
State and local		(298	)		48			65
Foreign		84			1,292			(636	)
Total current expense		(590	)		1,392			36
Deferred:
Federal		46,391			(24,425	)		(13,332	)
State and local		(1,436	)		(3,531	)		2,271
Foreign		2,426			2,058			(1,653	)
Total deferred expense (benefit)		47,381			(25,898	)		(12,714	)
Total income tax expense (benefit)	$	46,791		$	(24,506	)	$	(12,678	)

The domestic and foreign earnings before income taxes are as follows:

	2016		2015			2014
Domestic	$	61,006	$	(57,825	)	$	73,386
Foreign		28,410		40,605			16,163
Income (loss) before income taxes	$	89,416	$	(17,220	)	$	89,549

77

A reconciliation of differences between the U.S. federal statutory income tax rate and the effective income tax rates is presented as a percent of expense (benefit) as follows:

	2016			2015			2014
U.S. federal statutory income tax rate		35.0	%		(35.0	%)		35.0	%
State and local taxes based on income, net of federal benefit		1.1	%		(2.0	%)		2.2	%
Change in deferred foreign and state tax rates		(2.2	%)		(12.0	%)		(4.2	%)
Nondeductible customer incentive related to Amazon		10.9	%		—			—
Nondeductible compensation expenses related to Amazon		13.0	%		—			—
Other nondeductible expenses		4.3	%		10.2	%		2.2	%
Extraterritorial income tax benefit		—			(23.3	%)		(38.8	%)
Tax incentives and additional deductions		(0.9	%)		(4.9	%)		(3.8	%)
Favorable resolution of income tax issues		—			(13.8	%)		(1.5	%)
Tax effect of foreign operations		(9.4	%)		(66.4	%)		(5.7	%)
Other		0.5	%		4.9	%		0.4	%
Effective income tax rate		52.3	%		(142.3	%)		(14.2	%)

The effective income tax rate for the twelve months ended December 31, 2016 differed from the U.S. federal statutory rate primarily due to a nondeductible customer incentive and to nondeductible compensation expenses resulting from a change in control, as defined under certain of the Company’s benefit plans, both related to the Amazon transaction (see Note 7). We also generated non-recurring tax benefits from extraterritorial income (“ETI”) in 2015 and 2014, which reduced our income tax rate in proportion to our income or loss.

We indefinitely reinvest the net earnings of certain foreign subsidiaries engaged in our Dry Leasing business, which favorably impacted our effective income tax rate for all three years. At December 31, 2016, our undistributed net earnings of foreign subsidiaries for which deferred taxes have not been provided were $103.7 million, and the unrecognized deferred tax liability associated with these earnings was $36.3 million.

78

Deferred tax assets and liabilities represent the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. The net noncurrent deferred tax asset (liability) was comprised of the following as of December 31:

	Assets (Liabilities)
	2016			2015
Deferred tax assets:
Net operating loss carryforwards and credits	$	454,749		$	437,408
Accrued compensation		17,036			16,523
Accrued legal settlements		25,442			35,909
Aircraft leases		16,109			14,863
Allowance for doubtful accounts		—			1,597
Goodwill and other intangibles		15,798			—
Interest rate derivatives		3,124			3,825
Long-term debt		3,409			3,827
Obsolescence reserve		7,804			6,723
Stock-based compensation		6,731			5,385
Other		686			1,869
Total deferred tax assets		550,888			527,929
Valuation allowance		(49,396	)		(50,711	)
Net deferred tax assets	$	501,492		$	477,218
Deferred tax liabilities:

Total deferred tax liabilities	$	(798,437	)	$	(762,874	)

	Assets (Liabilities)
	2016			2015
Deferred taxes included within following balance sheet line items:
Deferred taxes	$	(298,165	)	$	(286,928	)
Deferred costs and other assets		1,219			1,272
Net deferred tax assets (liabilities)	$	(296,946	)	$	(285,656	)

As of December 31, 2016 and 2015, we had U.S. federal tax net operating losses (“NOLs”), net of unrecognized tax benefits and valuation allowances, of approximately $991.0 million and $951.6 million, respectively, which will expire through 2036, if not utilized. The increase in NOLs during 2016 resulted primarily from accelerated tax depreciation and from the acquisition of Southern Air (see Note 4). We had alternative minimum tax credits of $4.7 million and $5.2 million as of December 31, 2016 and 2015, respectively, with no expiration date. Additionally, we had foreign NOLs for Hong Kong and Singapore of approximately $463.5 million and $428.8 million as of December 31, 2016 and 2015, respectively, with no expiration date.

79

Section 382 of the Internal Revenue Code (the “Code”) imposes an annual limitation on the amount of a corporation’s U.S. federal taxable income that can be offset by NOLs if it experiences an “ownership change”, as defined. We experienced ownership changes, as defined, in 2004 and 2009. Accordingly, the use of our NOLs generated prior to these ownership changes is subject to an annual limitation. If certain changes in our ownership occur prospectively, there could be an additional annual limitation on the amount of utilizable carryforwards.

On each reporting date, management assesses whether we are more likely than not to realize some or all of our deferred tax assets. After our assessment, we maintained a valuation allowance of $49.4 million, $50.7 million and $50.8 million against our deferred tax assets as of December 31, 2016, 2015 and 2014, respectively. We recorded a decrease to the valuation allowance of $1.3 million during the year ended December 31, 2016, and decreases of $0.1 million and increase of $3.0 million during the years ended 2015 and 2014, respectively. The valuation allowance is attributable to a limitation on NOL utilization resulting from the ownership change under Section 382. Due to this limitation, we expect a portion of our NOLs generated in 2004 and prior years to eventually expire unused.

A reconciliation of the beginning and ending unrecognized income tax benefits is as follows:

	2016			2015			2014
Beginning balance	$	112,555		$	109,993		$	76,679
Additions for tax positions related to the current year		1,587			551			1,614
Additions for tax positions related to prior years		—			5,503			32,933
Reductions for tax positions related to prior years		(250	)		(3,492	)		(1,233	)
Ending balance	$	113,892		$	112,555		$	109,993

If recognized, all of the unrecognized income tax benefits would favorably impact the effective income tax rate. We will maintain a liability for unrecognized income tax benefits until these uncertain positions are resolved or until the expiration of the applicable statute of limitations, if earlier.

Our policy is to record tax-related interest expense and penalties, if applicable, as a component of income tax expense. We recorded no interest benefit in 2016 or 2015. The cumulative liability for tax-related interest was $0.1 million as of December 31, 2016 and December 31, 2015. We have not recorded any liability for income tax-related penalties, and the tax authorities historically have not assessed any.

For U.S. federal income tax purposes, the 2012 through 2016 income tax years remain subject to examination. We also file income tax returns in multiple states as well as in Hong Kong and Singapore. Generally, the 2012 through 2016 income tax years remain subject to examination in the states where we file. In addition, 2011 through 2016 Singapore income tax years and 2010 through 2016 Hong Kong income tax years are subject to examination. No income tax examinations are in process.

12.    Financial Instruments

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). Inputs used to measure fair value are classified in the following hierarchy:

Level 1	Unadjusted quoted prices in active markets for identical assets or liabilities;
Level 2	Other inputs that are observable directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, or inactive quoted prices for identical assets or liabilities in inactive markets;
Level 3	Unobservable inputs reflecting assumptions about the inputs used in pricing the asset or liability.

80

We endeavor to utilize the best available information to measure fair value.

The carrying value of Cash and cash equivalents, Short-term investments and Restricted cash is based on cost, which approximates fair value.

Long-term investments consist of debt securities for which we have both the ability and the intent to hold until maturity. These investments are classified as held-to-maturity and reported at amortized cost. The fair value of our Long-term investments is based on a discounted cash flow analysis using the contractual cash flows of the investments and a discount rate derived from unadjusted quoted interest rates for debt securities of comparable risk. Such debt securities represent investments in PTCs related to EETCs issued by Atlas in 1998, 1999 and 2000. Interest on debt securities and accretion of discounts using the effective interest method are included in Interest income.

The fair value of our term loans, notes guaranteed by the Ex-Im Bank and EETCs are based on a discounted cash flow analysis using current borrowing rates for instruments with similar terms.

The fair value of our Convertible Notes is based on unadjusted quoted market prices for these securities.

The fair value of the Amazon Warrant is based on a Monte Carlo simulation which requires inputs such as our common stock price, the warrant strike price, estimated common stock price volatility, and risk-free interest rate, among others.

The following table summarizes the carrying value, estimated fair value and classification of our financial instruments as of:

	December 31, 2016

The following table presents the carrying value, gross unrealized gain (loss) and fair value of our long-term investments and accrued interest by contractual maturity as of:

	December 31, 2016						December 31, 2015
	Carrying Value		Gross Unrealized Gain (Loss)		Fair Value		Carrying Value		Gross Unrealized Gain (Loss)		Fair Value

Total	$	27,951	$	5,210	$	33,161	$	37,604	$	8,263	$	45,867

Our Long-term investments include investments in PTCs related to EETCs. During 2015, we repaid EETCs related to five 747-400 freighter aircraft owned by us using proceeds from the Convertible Notes (see Note 9). Following the refinancing, we recognized a $13.4 million Gain on investments resulting from the early redemption of certain PTCs, of which $5.7 million was related to the receipt of debt redemption premiums and $7.7 million was related to the recognition of deferred income on the PTCs purchased at a discount that have been repaid. The early redemption of PTCs does not impact our ability or intent to hold the remainder of our PTC investments to maturity.

13.    Segment Reporting

Our business is organized into three operating segments based on our service offerings: ACMI, Charter and Dry Leasing. All segments are directly or indirectly engaged in the business of air transportation services but have different commercial and economic characteristics. Each operating segment is separately reviewed by our chief operating decision maker to assess operating results and make resource allocation decisions. We do not aggregate our operating segments and, therefore, our operating segments are our reportable segments.

We use an economic performance metric (“Direct Contribution”) that shows the profitability of each segment after allocation of direct operating and ownership costs. Direct Contribution represents Income (loss) from continuing operations before income taxes excluding the following: Special charges, Transaction-related expenses, nonrecurring items, Losses (gains) on the disposal of aircraft, Losses on early extinguishment of debt, Unrealized losses (gains) on financial instruments, Gains on investments and Unallocated income and expenses,

82

net. Direct operating and ownership costs include crew costs, maintenance, fuel, ground operations, sales costs, aircraft rent, interest expense on the portion of debt used for financing aircraft, interest income on debt securities and aircraft depreciation. Unallocated income and expenses, net include corporate overhead, nonaircraft depreciation, noncash expenses and income, interest expense on the portion of debt used for general corporate purposes, interest income on nondebt securities, capitalized interest, foreign exchange gains and losses, other revenue and other non-operating costs.

Management allocates the costs attributable to aircraft operation and ownership among the various segments based on the aircraft type and activity levels in each segment. Depreciation and amortization expense, aircraft rent, maintenance expense, and other aircraft related expenses are allocated to segments based upon aircraft utilization because certain individual aircraft are utilized across segments interchangeably. In addition, certain ownership costs are directly apportioned to the ACMI segment. Other allocation methods are standard activity-based methods that are commonly used in the industry.

The ACMI segment provides aircraft, crew, maintenance and insurance services to customers. Also included in the ACMI segment is CMI, whereby we provide crew, maintenance and insurance services but not the aircraft. Under ACMI and CMI contracts, customers generally guarantee a monthly level of operation at a predetermined rate for a defined period of time. The customer bears the commercial revenue risk and the obligation for other direct operating costs, including fuel.

The Charter segment provides full-planeload air cargo and passenger aircraft charters to customers, including the U.S. Military Air Mobility Command (the “AMC”), brokers, freight forwarders, direct shippers, airlines, sports teams and fans, and private charter customers. Charter customers generally pay a fixed charter fee and we bear the direct operating costs.

The Dry Leasing segment provides for the leasing of aircraft and engines to customers.

Other represents revenue for services that are not allocated to any segment, including administrative and management support services and flight simulator training.

83

The following table sets forth Operating Revenue and Direct Contribution for our reportable segments reconciled to Operating Income and Income (loss) from continuing operations before income taxes:

We are exposed to a concentration of revenue from the AMC and Polar (see Note 3 for further discussion regarding Polar). No other customer accounted for more than 10.0% of our Total Operating Revenue. Revenue from the AMC was $436.1 million in 2016 and $418.3 million in 2015. Accounts receivable from the AMC were $9.0 million and $26.3 million as of December 31, 2016 and December 31, 2015, respectively. We have not experienced any credit issues with either of these customers.

14.    Labor and Legal Proceedings

Labor

Pilots of Atlas and Southern Air, and flight dispatchers of Atlas and Polar are represented by the International Brotherhood of Teamsters (the “IBT”). We have a five-year collective bargaining agreement (“CBA”) with our Atlas pilots, which became amendable in September 2016 and a four-year CBA with the Southern Air pilots, which became amendable in November 2016. We also have a five-year CBA with our Atlas and Polar dispatchers, which becomes amendable in November 2017.

After we completed the acquisition of Southern Air in April 2016, we informed the IBT of our intention to pursue (and we have been pursuing) a complete operational merger of Atlas and Southern Air. Pursuant to the merger provisions in both the Atlas and Southern Air CBAs, joint negotiations for a single CBA for Atlas and Southern Air should commence promptly. Once a seniority list is presented to us by the unions, it triggers an agreed-upon time frame to negotiate a new joint CBA with any unresolved issues submitted to binding arbitration. After the merger process began, the IBT filed an application for mediation with the National Mediation Board (“NMB”) on behalf of the Atlas pilots. We have opposed the mediation application as it is not in accordance with the merger provisions in the parties’ existing CBAs, which have a defined and streamlined process for negotiating a joint CBA when a merger occurs, as in the case with the Atlas and Southern Air merger. The NMB conducted a pre-mediation investigation in June 2016, which is currently pending. Due to a lack of meaningful progress in such discussions, in February 2017, we filed a lawsuit against the IBT to compel arbitration on the issue of whether the merger provisions in Atlas and Southern Air’s CBAs apply to the bargaining process.

We are subject to risks of work interruption or stoppage as permitted by the Railway Labor Act of 1926 (the “Railway Labor Act”) and may incur additional administrative expenses associated with union representation of our employees.

Matters Related to Alleged Pricing Practices

The Company and Polar Air Cargo, LLC (“Old Polar”), a consolidated subsidiary, were named defendants, along with a number of other cargo carriers, in several class actions in the U.S. arising from allegations about the pricing practices of Old Polar and a number of air cargo carriers. These actions were all centralized in the U.S. District Court for the Eastern District of New York. Polar was later joined as an additional defendant. The consolidated complaint alleged, among other things, that the defendants, including the Company and Old Polar, manipulated the market price for air cargo services sold domestically and abroad through the use of surcharges, in violation of U.S., state, and European Union antitrust laws. The suit sought treble damages and attorneys’ fees.

85

On January 7, 2016, the Company, Old Polar, and Polar entered into a settlement agreement to settle all claims by participating class members against the Company, Old Polar and Polar. The Company, Polar, and Old Polar deny any wrongdoing, and there is no admission of any wrongdoing in the settlement agreement. Pursuant to the settlement agreement, the Company, Old Polar and Polar have agreed to make installment payments over three years to settle the plaintiffs’ claims, with payments of $35.0 million paid on January 15, 2016, $35.0 million due on or before January 15, 2017, and $30.0 million due on or before January 15, 2018. The U.S. District Court for the Eastern District of New York issued an order granting preliminary approval of the settlement on January 12, 2016. On October 6, 2016, the final judgment was issued and the settlement was approved.

In the United Kingdom, several groups of named claimants have brought suit against British Airways in connection with the same alleged pricing practices at issue in the proceedings described above and are seeking damages allegedly arising from that conduct. British Airways has filed claims in the lawsuit against Old Polar and a number of air cargo carriers for contribution should British Airways be found liable to claimants. Old Polar’s formal statement of defense was filed on March 2, 2015. On October 14, 2015, the U.K. Court of Appeal released decisions favorable to the defendant and contributory defendants on two matters under appeal. Permission has been sought to appeal the U.K. Court of Appeal’s decisions to the U.K. Supreme Court. In December 2015, certain claimants settled with British Airways removing a significant portion of the claim against British Airways and therefore reducing the potential contribution required by the other airlines, including Old Polar. On December 16, 2015, the European General Court released decisions annulling decisions that the European Commission made against the majority of the air cargo carriers. The European Commission did not appeal the General Court decision, but may still reopen its investigation or reissue a revised decision, either of which would have a significant impact on the proceedings in the U.K. court. Future procedures, including the pretrial disclosure process, are continuing. We are unable to reasonably predict the outcome of the litigation.

In the Netherlands, Stichting Cartel Compensation, successor in interest to claims of various shippers, has filed suit in the district court in Amsterdam against British Airways, KLM, Martinair, Air France, Lufthansa and Singapore Airlines seeking recovery for damages purportedly arising from the same pricing practices at issue in the proceedings described above. In response, British Airways, KLM, Martinair, Air France and Lufthansa filed third-party indemnification lawsuits against Old Polar and Polar seeking indemnification in the event the defendants are found to be liable in the main proceedings. Old Polar and Polar entered their initial court appearances on September 30, 2015. Various procedural issues are undergoing court review. Like the U.K. proceedings, the Netherlands proceedings are likely to be affected by the European Commission’s response to the European General Court decisions of December 16, 2015. We are unable to reasonably predict the outcome of the litigation.

If the Company, Old Polar or Polar were to incur an unfavorable outcome in connection with the U.K. or Netherlands proceedings, such outcome may have a material adverse impact on our business, financial condition, results of operations or cash flows. We are unable to reasonably estimate a range of possible loss for such matters at this time.

Brazilian Customs Claim

Old Polar was cited for two alleged customs violations in Sao Paulo, Brazil, relating to shipments of goods dating back to 1999 and 2000. Each claim asserts that goods listed on the flight manifest of two separate Old Polar scheduled service flights were not on board the aircraft upon arrival and therefore were improperly brought into Brazil. The two claims, which also seek unpaid customs duties, taxes and penalties from the date of the alleged infraction, are approximately $9.3 million in aggregate based on December 31, 2016 exchange rates.

In both cases, we believe that the amounts claimed are substantially overstated due to a calculation error when considering the type and amount of goods allegedly missing, among other things. Furthermore, we may seek appropriate indemnity from the shipper in each claim as may be feasible. In the pending claim for one of the

86

cases, we have received an administrative decision dismissing the claim in its entirety, which remains subject to a mandatory appeal by the Brazil customs authorities. As required to defend such claims, we have made deposits pending resolution of these matters. The balances were $5.0 million as of December 31, 2016 and $3.8 million as of December 31, 2015, and are included in Deposits and other assets.

We are currently defending these and other Brazilian customs claims and the ultimate disposition of these claims, either individually or in the aggregate, is not expected to materially affect our financial condition, results of operations or cash flows.

Accruals

As of December 31, 2016, the Company had a remaining accrual of $65.0 million related to the U.S. class action settlement that was recognized in 2015. During 2016, the Company recorded a net accrual of $6.2 million within Other operating expense in the consolidated statement of operations related to pending litigation outside of the U.S.

Other

We have certain other contingencies incident to the ordinary course of business. Management believes that the ultimate disposition of such other contingencies is not expected to materially affect our financial condition, results of operations or cash flows.

15.    Stock-Based and Long-term Incentive Compensation Plans

In 2007, our stockholders approved a Long-Term Incentive Plan (the “2007 Plan”). An aggregate of 0.6 million shares of common stock was reserved for issuance to participants under the 2007 Plan. The 2007 Plan provided for stock awards of up to approximately 2.8 million shares of AAWW’s common stock to employees in various forms, including cash awards and performance cash awards. Stock awards included nonqualified options, incentive stock options, share appreciation rights, restricted shares, restricted share units, performance shares and performance units, dividend equivalents and other share-based awards. In 2016, the stockholders approved a revised Long-Term Incentive Plan (the “2016 Plan”), which replaced the 2007 Plan. An aggregate of 0.7 million shares of common stock was reserved for issuance to participants under the 2016 Plan. No new awards have been made under the 2007 Plan since the adoption of the 2016 Plan in May 2016. Awards outstanding under the 2007 Plan will continue to be governed by the terms of that plan and agreements under which they were granted. The 2016 Plan limits the terms of awards to ten years and prohibits the granting of awards more than ten years after the effective date of the 2016 Plan.

As of December 31, 2016, the 2016 Plan had a total of 0.7 million shares of common stock available for future award grants to management and members of the board of directors. Including the impact of the change in control as defined under the benefit plan in 2016 (see Note 7), our compensation expense for both plans was $30.9 million in 2016, $15.0 million in 2015 and $12.5 million in 2014. Income tax benefits recognized for share-based compensation arrangements were $8.7 million in 2016, $5.7 million in 2015 and $4.0 million in 2014. The excess cash tax effect classified as a financing cash inflow was a nominal benefit in 2016, 2015 and 2014.

Nonqualified Stock Options

The portion of the 2016 Plan and the 2007 Plan applicable to employees is administered by the compensation committee of the board of directors, which also establishes the terms of the awards.

Nonqualified stock options, which have not been granted since 2007, vest over a three or four year period and expire seven to ten years from the date of grant. While nonqualified stock options may be granted at any price, they have never been granted with an exercise price less than the fair market value of the stock on the date of grant.

87

A summary of our options as of December 31, 2016 and changes during the year then ended is presented below:

	Number of Options			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value (in thousands)
Outstanding as of December 31, 2015		34,700		$	58.41
Granted		—			—
Exercised		(30,200	)		58.34
Forfeited, net of adjustments		—			—
Outstanding as of December 31, 2016		4,500		$	58.89		—	$	—
Exercisable as of December 31, 2016		4,500		$	58.89		—	$	—

The total intrinsic value of options exercised in 2016 and 2015 was nominal and the cash received was zero and $1.2 million, respectively. No options were exercised in 2014.

As of December 31, 2016, there was no unrecognized compensation cost related to non-vested stock options granted and all options have vested.

Restricted Share Awards

Restricted shares granted vest and are expensed over one-, three- or four- year periods. Restricted share awards have been granted in both shares and units. As of December 31, 2016, a total of 3.5 million restricted shares have been granted under the 2007 and 2016 Plans. All shares were valued at their fair market value on the date of issuance. Unrecognized compensation cost as of December 31, 2016 is $18.9 million and will be recognized over the remaining weighted average life of 2.1 years.

A summary of our restricted shares as of December 31, 2016 and changes during the year then ended are presented below:

Restricted Share Awards	Number of Shares			Weighted-Average Grant-Date Fair Value
Unvested as of December 31, 2015		840,879		$	40.52
Granted		428,314			36.10
Vested		(522,994	)		37.84
Forfeited		(16,053	)		38.54
Unvested as of December 31, 2016		730,146		$	39.89

The total fair value of shares vested on various vesting dates was $19.8 million in 2016, $13.7 million in 2015 and $11.3 million in 2014. Weighted average grant date fair value was $47.10 in 2015 and $33.21 in 2014.

Performance Share and Performance Cash Awards

Performance share and performance cash awards granted are expensed over three years, which generally is the requisite service period. Awards generally become vested if (1) we achieve certain specified performance levels compared with predetermined performance thresholds during a three-year period starting in the grant year and ending on December 31 three years later, and (2) the employee remains employed by us through the determination date which can be no later than four months following the end of the Performance Period. Partial

88

vesting may occur for certain employee terminations. As a result of a change in control as defined under the benefit plan (see Note 7), the performance levels are deemed to be achieved for all performance share and performance cash awards outstanding as of December 31, 2016. Performance share awards have been granted to employees in shares and units. All performance share and performance cash awards are valued at their fair market value on the date of grant. The estimated compensation expense recognized for performance share and performance cash awards are net of estimated forfeitures. We assess the performance levels in the first quarter of each year for the prior year. We review the results, adjust the estimated performance level and record any change to compensation cost. As of December 31, 2016, a total of 1.7 million performance shares have been granted. Unrecognized compensation cost as of December 31, 2016 is $8.3 million and will be recognized over the remaining weighted average life of 1.7 years. For the performance cash awards, we had accruals of $13.1 million as of December 31, 2016 and $4.0 million as of December 31, 2015 in Other liabilities. Including the impact of the change in control as defined under the benefit plan in 2016, we recognized compensation expense associated with the performance cash awards totaling $13.9 million in 2016, $1.6 million in 2015 and $1.3 million in 2014.

A summary of our performance shares as of December 31, 2016 and changes during the year then ended are presented below:

Performance Share Awards	Number of Shares			Weighted-Average Grant-Date Fair  Value
Unvested as of December 31, 2015		334,692		$	23.85
Granted		494,894			37.21

Forfeited		(101,701	)		47.76
Unvested as of December 31, 2016		576,166		$	27.30

The total fair value of shares vested on various vesting dates in 2016 was $5.8 million, $3.7 million in 2015 and $7.0 in 2014. Weighted average grant date fair value was $47.48 in 2015 and $32.2 in 2014.

16.    Profit Sharing, Incentive and Retirement Plans

Profit Sharing and Incentive Plans

We have an annual incentive compensation program for management employees. The program provides for payments to eligible employees based upon our financial performance, service performance and attainment of individual performance goals, among other things. In addition, our profit sharing plan allows IBT-represented Atlas crewmembers to receive payments from the plan based upon Atlas’ financial performance. The profit sharing plan is subject to a minimum financial performance threshold. For both plans, we had accruals of $22.1 million as of December 31, 2016 and $27.0 million as of December 31, 2015 in Accrued liabilities. Including the impact of the change in control as defined under the benefit plan in 2016 (see Note 7), we recognized compensation expense associated with both plans totaling $21.8 million in 2016, $28.5 million in 2015 and $21.7 million in 2014.

401(k) and 401(m) Plans

Participants in our retirement plan may contribute a portion of their annual compensation to a 401(k) plan on a pretax basis, subject to aggregate limits under the Code. In addition to 401(k) contributions, participants may contribute a portion of their eligible compensation to a 401(m) plan on an after-tax basis. On behalf of participants in the plan who make elective compensation deferrals, we provide a matching contribution subject to certain limitations. Employee contributions in the plan are vested at all times and our matching contributions are subject to a three-year cliff vesting provision, except for employees who are represented by a collective bargaining agreement and are subject to a three-year graded vesting provision. We recognized compensation expense associated with the plan matching contributions totaling $10.5 million in 2016, $9.5 million in 2015 and $8.5 million in 2014.

89

17.    Stock Repurchases

We record the repurchase of our shares of common stock at cost based on the settlement date of the transaction. These shares are classified as treasury stock, which is a reduction to stockholders’ equity. Treasury shares are included in authorized and issued shares but excluded from outstanding shares.

In 2008, we established a stock repurchase program authorizing the repurchase of up to $100.0 million of our common stock. In November 2013, we announced an increase of $51.0 million to our stock repurchase program. As of December 31, 2016, we had repurchased a total of 3,307,911 shares of our common stock for approximately $126.0 million under this program, resulting in $25.0 million of available authorization remaining. Purchases may be made at our discretion in the form of open market repurchase programs, privately negotiated transactions, accelerated share repurchase programs or a combination of these methods. The actual timing and amount of our repurchases will depend on Company and market conditions.

In addition, we repurchased 297,569 and 140,198 shares of common stock from management, in connection with the vesting of equity awards to pay the statutory tax withholdings of employees, at an average price of $37.89 per share in 2016 and $46.54 per share in 2015, and held the shares as treasury shares.

18.    Earnings Per Share

Basic earnings per share (“EPS”) represent net income divided by the weighted average number of common shares outstanding during the measurement period. Diluted EPS represent net income divided by the weighted average number of common shares outstanding during the measurement period while also giving effect to all potentially dilutive common shares that were outstanding during the period using the treasury stock method. Anti-dilutive shares related to warrants and stock options that were out of the money and excluded for 2016 were 3.3 million, 2015 were 3.0 million, and were de minimis for 2014.

The calculations of basic and diluted EPS were as follows:

	For the Years Ended December 31,
	2016			2015		2014
Numerator:
Income from continuing operations, net of taxes	$	42,625		$	7,286	$	102,227
Denominator:
Basic EPS weighted average shares outstanding		24,843			24,833		25,031
Effect of dilutive stock options and restricted stock		277			185		96
Diluted EPS weighted average shares outstanding		25,120			25,018		25,127
Earnings per share from continuing operations:
Basic	$	1.72		$	0.29	$	4.08
Diluted	$	1.70		$	0.29	$	4.07
Loss per share from discontinued operations:
Basic	$	(0.04	)	$	—	$	—
Diluted	$	(0.04	)	$	—	$	—
Earnings per share:
Basic	$	1.67		$	0.29	$	4.08
Diluted	$	1.65		$	0.29	$	4.07

90

Diluted shares reflect the potential dilution that could occur from stock options and restricted shares using the treasury stock method. The calculation of EPS does not include restricted share units and warrants in which performance or market conditions were not satisfied of 7.5 million in 2016, 0.3 million in 2015 and 0.4 million in 2014.

19.    Accumulated Other Comprehensive Income (Loss)

The following table summarizes the components of Accumulated other comprehensive income (loss):

	Interest Rate Derivatives			Foreign Currency Translation			Total

Interest Rate Derivatives

As of December 31, 2016, there was $8.1 million of net unamortized realized loss before taxes remaining in Accumulated other comprehensive income (loss) related to forward-starting interest rate swaps terminated in prior years, which had been designated as cash flow hedges to effectively fix the interest rates on two 747-8F financings in 2011 and three 777-200LRF financings in 2014. The net loss is amortized and reclassified into Interest expense over the remaining life of the related debt. Net realized loss reclassified into earnings was $1.8 million in 2016 and $6.1 million in 2015. Net realized loss expected to be reclassified into earnings within the next 12 months is $1.6 million as of December 31, 2016.

** In 2016, the sum of quarterly diluted EPS amounts differs from the full year diluted EPS. The difference primarily relates to the exclusion from the calculation of diluted EPS of an unrealized gain on financial instruments in the second quarter and anti-dilutive shares in the third quarter, both related to the Amazon Warrant.

*** Included in the third quarter was a pretax loss on early extinguishment of debt of $66.7 million, a gain on investments of $13.4 million and a special charge of $7.7 million.

Exhibit 10.9

ATLAS AIR WORLDWIDE HOLDINGS, INC.

ANNUAL INCENTIVE PROGRAM

FOR SENIOR EXECUTIVES

Amended by Compensation Committee: As of February 24, 2015

ATLAS AIR WORLDWIDE HOLDINGS, INC.

ANNUAL INCENTIVE PROGRAM

FOR SENIOR EXECUTIVES

Section 1. Purpose.

The purpose of the Program is to set forth certain terms and conditions governing cash awards made under Atlas Air Worldwide Holdings, Inc.’s (“AAWW”) 2007 Incentive Plan, as amended (the “Plan”). The Program shall be treated for all purposes as a sub-plan or arrangement for the grant of Cash Awards under the Plan. Awards under the Program are intended to qualify for the performance-based compensation exception to the limitations on tax deductibility imposed by Section 162(m) of the Code and together with the applicable terms of the Plan and Program shall be construed accordingly. The Program shall be effective as of January 1, 2007, and shall be applicable for the 2007 Program Year and subsequent Program Years during the continuance of the Plan unless amended or terminated by the Committee pursuant to Section 10. Capitalized terms not defined herein shall have the meanings given in the Plan.

Section 2. Definitions.

2.1. Award shall mean an opportunity to earn benefits under the Program.

2.2. Atlas shall mean AAWW or its subsidiaries, as applicable.

2.3. Base Salary shall mean an Eligible Employee’s actual base salary for the applicable period.

2.4. Board shall mean the Board of Directors of AAWW.

2.5. Beneficiary shall mean a Participant’s beneficiary designated pursuant to Section 8.

2.6. Code shall mean the Internal Revenue Code of 1986, as amended from time to time.

2.7. Committee shall mean the Compensation Committee of the Board.

2.8. Eligible Employee means any of the Chief Executive Officer, President, Executive Vice Presidents and Senior Vice Presidents of AAWW and such other Atlas senior executive officers as shall be designated by the Committee.

2.9. Participant shall mean any Eligible Employee during such Eligible Employee’s period of participation in the Program.

2.10. Program shall mean this Atlas Air Worldwide Holdings, Inc. Annual Incentive Program for Senior Executives, as it may be amended from time to time.

2.11. Program Year shall mean the calendar year.

1

Section 3. Administration.

The Program shall be administered by the Committee. The Committee shall have full power and authority in its sole discretion to construe and interpret the Program, establish and amend administrative regulations to further the purpose of the Program, determine the extent to which Award payments have been earned by virtue of satisfying the financial goal described in Section 5.2, determine whether to reduce under Sections 5.2(b) through 5.2(e), to the extent that cost control, service reliability, management-business objectives and any other performance criteria have not been satisfied, the amount otherwise payable under Section 5.2, determine whether to settle a portion of the Award in Atlas stock and take any other action necessary to administer the Program. All decisions, actions or interpretations of the Committee shall be final, conclusive, and binding upon all Participants.

Section 4. Participation.

Each Eligible Employee shall participate in the Program if he or she is employed as an Eligible Employee on the first day of the Program Year. An individual who becomes an Eligible Employee during a Program Year but prior to September 30 of the applicable year will participate only with respect to Base Salary earned on and after the date he or she first becomes an Eligible Employee. Any determination by the Committee to provide incentive compensation to an Eligible Employee other than as described in the preceding two sentences shall be treated as a separate award made outside the Program.

Section 5. Section 5: Determination of Awards.

5.1. Maximum Bonus Award. The maximum bonus payable under an Award for each Program Year will be the lesser of (i) the dollar limit set forth in Section 4.c of the Plan, and (ii) the following percentage of Base Salary for each Participant, as such percentages may be increased by the Committee from time to time: two-hundred percent (200%) of Base Salary for the Chief Executive Officer, one-hundred eighty percent (180%) of Base Salary for Executive Vice Presidents who also hold the title of President of Atlas Air, Inc. or Chief Executive Officer of Titan Aviation Holdings, Inc., and one-hundred and seventy percent (170%) of Base Salary for other Executive Vice Presidents.

5.2. Performance Measures. Payment under an Award is conditioned upon achievement of the threshold Financial Goal, as described below. If the threshold Financial Goal is achieved, the Award payment will be the maximum bonus amount described in Section 5.1 minus such adjustments, if any, as the Committee determines to be appropriate to reflect levels of achievement with respect to the Financial Goal (if that Goal is achieved at a level below the maximum level) and/or one or more of the other factors described below and/or such other factors as shall be designated by the Committee.

(a) Financial Goal. The financial goal is based on Atlas’s earnings per share. For each Program Year, the threshold earnings per share level (which must be met before any amounts will be payable under Awards), the maximum earnings per share level, intermediate earnings per share levels, and the percentage of each Participant’s target bonus award that will be deemed achieved at each such profit level, will be determined by the Committee.

(b) Cost Control Adjustment. The Committee may reduce maximum Award payments, if any, to reflect the level of achievement of such cost control goal or goals as the Committee may establish for the Program Year.

2

(c) Service Reliability. The Committee may also reduce maximum Award payments, if any, to reflect the level of achievement of such service reliability factors as the Committee may determine for the Program Year.

(d) Management Business Objectives Adjustment. The Committee may also reduce maximum Award payments, if any, to reflect the level of achievement of such individual management business objectives as the Committee may determine in the case of any Participant for the Program Year.

(e) Effect of Corporate Transactions and other Exigencies. Without limiting the generality of the foregoing, the Committee shall have the authority, to the extent consistent with the requirements for satisfying the performance-based compensation exception under 162(m) of the Code, to identify objectively determinable events (for example, but without limitation, acquisitions or dispositions) which, if they occur, would have a material effect on objective Performance Criteria applicable to Awards under the Program, and to adjust such Performance Criteria in an objectively determinable manner to reflect such events.

Section 6. Payment of Awards under this Program.

6.1. General. Subject to Section 6.4, Participant will be entitled to receive payment, if any, under an Award if the Participant is still employed by Atlas on the last day of the Program Year for which the Award is paid, unless in the period between the last day of the Program Year and any payout under the Program, the Participant is terminated by Atlas for Cause (as defined in Section 7) or the Participant terminates his employment with Atlas for any reason. A Participant will receive an Award in the manner and at the times set forth in this Sections 6.

6.2. Time of Payment. Any amount payable for an Award for a Program Year shall be paid by Atlas within two weeks following certification by the Committee as to achievement of the performance goals following the completion of the year-end audit for the applicable Program Year, but in no event later than March 15 of the year following the applicable Program Year.

6.3. Form of Payment. All amounts payable for an Award shall be paid in cash or Atlas stock, but Atlas stock may be used, if at all, only for the portion of the Award that exceeds fifty percent (50%) of Base Salary.

3

6.4. Termination of Employment.

(a) In General. Except as provided otherwise in this Section 6.4, a Participant whose employment terminates for any reason prior to the last day of the Program Year for which an Award is payable shall forfeit such Award.

(b) Death or Disability. In the event of death or termination by the Company of the Participant’s employment with the Company or its Subsidiaries (a “Termination of Service”) by reason of the Participant’s Disability the Committee may, in its sole discretion, direct that all or a portion of a Participant’s Award be paid, taking into account the duration of employment during the Program Year, the Participant’s performance, and such other matters as the Committee shall deem appropriate. For purposes of this Agreement, a termination of Service shall be deemed to be by reason of “Disability” if upon such Termination of Service, the Participant shall have been continuously disabled from performing the duties assigned to the Participant for a period of not less than six consecutive calendar months and such Disability shall be deemed to have commenced on the date following the end of such six consecutive calendar months.

(c) Retirement; Involuntary Termination; Good Reason. If a Participant’s employment terminates during a Program Year by reason of (i) an involuntary termination by Atlas not for Cause (as defined in Section 7 below), (ii) termination by the Participant for Good Reason (as defined below), or (iii) in the sole discretion of the Committee, normal retirement under a retirement program of Atlas, the Participant shall be entitled to receive a payment with respect to an Award for the Program Year in which such termination occurred, if he or she had been employed by Atlas on the last day of such Program Year in an amount equal to the lesser of (1) the amount he or she would have received if he or she was employed by Atlas on the last day of the Program Year based upon actual company performance measured pursuant to the plan (and assuming for such purpose that 50% of his or her individual Management Business Objectives (“MBOs”) have been achieved), or (2) his or her Target Bonus Percentage. Such payment shall be subject to all terms and conditions of the Program, including without limitation the provisions of Section 5 (relating to determination of the Award) and Section 6.2 (relating to the time of payment of the Award). This Section 6.4 shall not apply to the extent the rights of a Participant in such circumstances are governed by another agreement. “Good Reason” under this Section 6 shall mean (i) a material reduction in Participant’s duties and responsibilities from those of Participant’s most recent position with Atlas, or (ii) a reduction of Participant’s aggregate salary, benefits and other compensation (other than bonus opportunity, which shall be paid as provided above) from that which the Participant was most recently entitled during employment with Atlas other than in connection with a reduction as part of a general reduction applicable to all participants in the Program. This Section 6.4 shall not apply to the extent the rights of a Participant in such circumstances are governed by another agreement.

Section 7. Change in Control.

In the event Atlas undergoes a Change in Control, Awards will be determined and paid in accordance with this Section 7 based on the assumption that each of the Financial Goal, the Cost Control Goal, the MBOs and any other Performance Criteria under Section 2 have been achieved

4

at a level of 100% of target for the Plan Year in which the Change in Control takes place pursuant to Section 5 of the Program; provided, however, if upon completion of the year-end audit for the applicable Program Year it is determined that the Financial Goal or any other Performance Criteria was achieved at a level higher than 100% of target, Awards will be correspondingly adjusted pursuant to Section 5 of the Program. Notwithstanding the above, a Participant whose employment with Atlas terminates prior to the Change in Control shall forfeit such Award, unless such termination is by reason of (i) death, (ii) Disability (as defined in the Plan), (iii) normal retirement under a retirement program of Atlas, (iv) by Atlas not for Cause, or (v) by the Participant for Good Reason (as defined below). For purposes of this Program, “Change in Control of Atlas” shall mean a “change in control event” (as that term is defined at Section 1.409A-3(i)(5) of the Treasury Regulations) with respect to the Company, which generally will include the following events, subject to such additional rules and requirements as may be set forth in the Treasury Regulations and related guidance:

(1) A transfer or issuance of stock of the Company, where stock in the Company remains outstanding after the transaction, and one person, or more than one person acting as a group (as determined under the Treasury Regulations), acquires ownership of stock in the Company that, together with stock held by such person or group, constitutes more than 50% of total fair market value or total voting power of the stock of the Company (however, if a person or group is considered to own more than 50% of the total fair market value or 30% of the total voting power of the stock of the Company, the acquisition of additional stock by the same person or group will not be considered a change in control for purposes of this Section 7);

(2) The acquisition by a person or group, during the 12-month period ending on the date of the most recent acquisition by such person or group, of ownership of stock possessing 30% or more of the total voting power of the Company (however, if a person or group is considered to control the Company within the meaning of this sentence (i.e. owns stock of the Company possessing 30% of the total voting power of the Company), then the acquisition of additional control will not be considered a change in control for purposes of this Section 7);

(3) The replacement of a majority of members of the Company’s Board of Directors during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Company’s Board of Directors before the appointment or election; or

(4) The acquisition by a person or group, during the 12-month period ending on the date of the most recent acquisition by such person or group, of assets from the Company that have a total gross fair market value equal to more than 40% of the total gross fair market value of all the assets of the Company, as determined under the Treasury Regulations, or to an entity that is controlled by the shareholders of the Company immediately after the transfer, will not be considered a change in control for purposes of this Section 7). For purposes of this Program, “Continuing Directors” shall mean the directors of Atlas on the date hereof and each other director, if such other director’s nomination for election to the Board of Directors of Atlas is recommended by a majority of the then Continuing Directors. “Cause” shall mean (i) the Participant’s refusal or failure (other than during periods of illness or Disability (as

5

defined in the Plan)) to perform his or her material duties and responsibilities to Atlas, (ii) the conviction or plea of guilty or nolo contendere of the Participant in respect of any felony, other than a motor vehicle offense, (iii) the commission of any act which causes material injury to the reputation, business or business relationships of Atlas including, without limitation, any material breach of written policies of Atlas with respect to trading in securities, (iv) other acts of fraud in connection with the Participant’s duties and responsibilities to Atlas, including, without limitation, misappropriation, theft or embezzlement in the performance of the Participant’s duties and responsibilities as an employee of Atlas, or (v) a violation of any material Atlas policy, including, without limitation, a violation of the laws against workplace discrimination. “Good Reason” under this Section 7 shall mean the failure of the surviving entity in the Change in Control, of failure of an affiliate of the surviving entity, to continue the Participant in a position with the surviving entity or affiliate that (a) is not located within 40 miles of the location of such Participant’s most recent principal location of employment with Atlas, (ii) does not involve substantially comparable duties and responsibilities as such Participant’s most recent position with Atlas, or (iii) does not entitle the Participant to salary, benefits and other compensation (other than bonus opportunity, which shall be paid as provided above) that, in the aggregate, are substantially comparable or more favorable than those to which the Participant most recently was entitled during employment with Atlas. This Section 7 shall not apply to the extent the rights of a Participant in such circumstances are governed by another agreement.

Section 8. Beneficiary Designation.

8.1. Designation and Change of Designation. Each Participant shall file with Atlas a written designation of one or more persons as the Beneficiary who shall be entitled to receive the Award, if any, payable under the Program upon the Participant’s death. A Participant may, from time to time, revoke or change his Beneficiary designation without the consent of any prior Beneficiary by filing a new designation with Atlas. The last such designation received by Atlas shall be controlling; provided, however, that no designation, or change or revocation thereof, shall be effective unless received by Atlas prior to the Participant’s death, and in no event shall it be effective as of any date prior to such receipt.

8.2. Absence of Valid Designation. If no such Beneficiary designation is in effect at the time of a Participant’s death, or if no designated Beneficiary survives the Participant, or if such designation conflicts with law, the Participant’s estate shall be deemed to have been designated as the Participant’s Beneficiary and shall receive the payment of the amount, if any, payable under the Program upon his death. If Atlas is in doubt as to the right of any person to receive such amount, Atlas may retain such amount, without liability for any interest thereon, until the rights thereto are determined, or Atlas may pay such amount into any court of appropriate jurisdiction and such payment shall be a complete discharge of the liability of the Program and Atlas therefor.

6

Section 9. General Provisions.

9.1. Plan to be Unfunded. The Program is intended to constitute an unfunded incentive compensation arrangement. Nothing contained in the Program, and no action taken pursuant to the Program, shall create or be construed to create a trust of any kind. A Participant’s right to receive an Award shall be no greater than the right of an unsecured general creditor of Atlas. All Awards shall be paid from the general funds of Atlas, and no special or separate fund shall be established and no segregation of assets shall be made to assure payment of such Awards. There shall not vest in any Participant or Beneficiary any right, title, or interest in and to any specific assets of Atlas.

9.2. Section 409A of the Code. Awards under the Program are intended to be exempt from the requirements of Section 409A of the Code and shall be construed and administered accordingly. Notwithstanding anything to the contrary in the Program, neither Atlas, nor any affiliate, nor the Committee, nor any person acting on behalf of Atlas, any affiliate, or the Committee, shall be liable to any Participant or to the estate or beneficiary of any Participant or to any other holder of an Award by reason of any acceleration of income, or any additional tax, asserted by reason of the failure of an Award to satisfy the requirements of Section 409A or by reason of Section 4999 of the Code; provided, that nothing in this Section 9.3 shall limit the ability of the Committee or Atlas to provide by separate express written agreement with a Participant for a gross-up payment or other payment in connection with any such tax or additional tax.

9.3. Rights Limited; Conflicts. Nothing contained in the Program shall give any Eligible Employee the right to continue in the employment of Atlas, or limit the right of Atlas to discharge an Eligible Employee. If there is a conflict between this Program and another senior executive employment program or arrangement, such other program or arrangement shall control.

9.4. Governing Law. The Program shall be construed and governed in accordance with the laws of the State of New York.

9.5. Taxes. There shall be deducted from all amounts paid under the Program all federal, state, local and other taxes required by law to be withheld with respect to such payments.

Section 10. Amendment, Suspension, or Termination.

Except with respect to 6.4(c) for any Program Year in effect, the Committee reserves the right to amend, suspend, or terminate the Program at any time.

Section 11. Awards Subject to Clawback

Pursuant to the Company’s Executive Compensation Clawback Policy, as the same is in effect following its adoption by the Board and as may be subsequently amended from time to time (the “Clawback Policy”), by his or her acceptance of an Award under the Program, the Participant agrees that the Committee may withhold, and participant will forfeit, compensation otherwise payable under an Award or seek recovery from, and the participant agrees to repay, compensation previously paid under an Award, as the case may be, as provided by the Clawback Policy, or to the extent required to comply with applicable law.

Cash Retainer

• Each of our outside Directors receives a $95,000 cash retainer, payable quarterly in advance.

Equity Compensation - Restricted Stock Units

• The Chairs of the Audit Committee, the Compensation Committee and the Nominating and Governance Committee receive $20,000, $15,000 and $15,000, respectively, per year.

Exhibit 14.1

CODE OF ETHICS APPLICABLE TO THE CHIEF EXECUTIVE OFFICER,

SENIOR FINANCIAL OFFICERS AND MEMBERS OF THE BOARD OF DIRECTORS

GENERAL

Atlas Air Worldwide Holdings, Inc. (“Atlas” or the “Company”) maintains an Employee Handbook and Code of Conduct (the “Handbook”) that is applicable to all of the Company’s officers and employees, as well as to individuals and entities who seek to provide goods and services to Atlas, and in certain circumstances to the non-employee members of the Company’s Board of Directors (“Non-Employee Directors”). The Company’s Chief Executive Officer, senior financial officers and its Board of Directors (collectively, the “Covered Persons”) play an important and elevated role in corporate governance at the Company. Each Covered Person shall therefore comply not only with the provisions of the Handbook (which sets forth standards for both business conduct and ethics) (except that the Company’s non-employee members of the Board of Directors shall comply with the Handbook only to the extent explicitly set forth in the Handbook and in this Code of Ethics as applicable to Non-Employee Directors), but also with the provisions of this Code of Ethics. If any conflict should arise between the terms of this Code of Ethics and the Handbook, the terms of this Code of Ethics shall govern.

For the purpose of this Code of Ethics, the senior financial officers of Atlas shall include the Chief Financial Officer, Treasurer and the Corporate Controller, or persons performing similar functions.

This Code of Ethics is intended to be a codification of standards that is reasonably designed to deter wrongdoing and to promote:

1. Honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

2. Avoidance of conflicts of interest, including internal disclosure of any material transaction or relationship that reasonably could be expected to give rise to such conflict;

3. Full, fair, accurate, timely and understandable disclosure in the reports and documents which Atlas files with, or submits to, the Securities and Exchange Commission (the “SEC”) and in other public communications made by Atlas;

4. Compliance with applicable governmental laws, rules and regulations;

5. The prompt internal reporting of violations of this Code of Ethics; and

6. Accountability for adherence to this Code of Ethics.

HONEST AND ETHICAL CONDUCT

Each Covered Person shall act with honesty and integrity, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships. The Covered Persons are expected to act in accordance with the highest of standards, thereby setting an example for other officers and employees of the Company. Each Covered Person shall comply with each provision of the Handbook (except that the Company’s non-employee members of the Board of Directors shall comply with the Handbook only to the extent explicitly set forth in the Handbook and in this Code of Ethics as applicable to Non-Employee Directors).

1

AVOIDANCE OF CONFLICTS OF INTEREST

Covered Persons shall be free from the influence of any conflicting interest between personal interests and the interest of the Company. They are expected to deal with suppliers, customers, contractors and all others doing business with Atlas on the sole basis of what is in the best interest of Atlas, without favor or preference to third parties based on personal considerations. Each Covered Person shall comply with the provisions under the heading “Conflict of Interest and Outside Activities” in the Handbook. In addition, the following guidelines should be followed:

1. Covered Persons should communicate any potential or actual conflict of interest (however immaterial) to the Chairman of the Board, the Chairman of the Audit Committee and the General Counsel so that an objective, third-party review can be made of the matter.

2. Subject to the Audit Committee Charter with respect to the Board of Directors, Covered Persons who render service with or without compensation to any person or group doing or seeking to do business with the Company, and Covered Persons who have (or have close relatives (i.e., parent, spouse, child or sibling) who have) a financial or other personal interest in any organization doing or seeking to do business with the Company, must clear this matter in writing with the Chairman of the Audit Committee.

3. Any lease or rental of any kind of facilities or equipment to the Company, or to any other company or individual dealing with the Company as a contractor or supplier, by a Covered Person (or a Covered Person’s close relative as defined above) must be disclosed in writing to the Chairman of the Audit Committee.

4. No Covered Person shall seek or accept, directly or indirectly, any personal loan or services from any individual or business concern doing or seeking to do business with the Company, except from financial institutions or service providers offering like loans or services to third parties under similar terms in the ordinary course of their respective businesses.

5. No Covered Person shall do business with a close relative (as defined above) on behalf of Atlas, unless expressly authorized in writing by the Chairman of the Audit Committee after the relationship has been disclosed.

6. Prior approval by the Chairman of the Audit Committee is required before a Covered Person (a) (other than a non-employee member of the Board of Directors) accepts a position as an officer or director of a “for profit” corporation, or (b) becomes a member of a business partnership or other entity that may compromise or otherwise create a perceived or actual conflict of interest with the Covered Person’s service to Atlas.

7. Covered Persons who seek elective or appointed public offices, as well as membership on public boards or commissions, may encounter situations that have the potential for conflict of interest. Covered Persons who serve in public bodies should disqualify themselves from actions that represent, or may appear to represent, a conflict of interest between their role as an employee or member of the Board of Directors of the Company and their role in the public body. Covered Persons who serve in these capacities shall notify the Chairman of the Audit Committee of their appointment or election when it occurs.

2

PUBLIC DISCLOSURES

Each Covered Person shall act to promote full, fair, accurate, timely and understandable disclosure in reports and documents that Atlas files with, or submits to, the SEC and in other public communications made by Atlas. Each Covered Person shall comply with the provisions under the headings “Financial Controls” and “Kickback, Rebates and Improper or Illegal Payments” (and any such related sections) in the Handbook. Additionally, each Covered Person should promptly bring to the attention of the Audit Committee any information concerning: (1) significant deficiencies or material control weaknesses in the design or operation of Atlas’ internal control over financial reporting; or (2) any fraud, whether or not material, that involves management or other employees who have a significant role in Atlas’ internal control over financial reporting.

COMPLIANCE WITH LAWS, RULES AND REGULATIONS

It is the Company’s policy to comply with all applicable laws, rules and regulations. Each Covered Person shall comply with all governmental laws, rules and regulations that are applicable to Atlas and to each such Covered Person (in his or her capacity as an employee or member of the Board of Directors, as applicable, of Atlas). Such compliance shall be more than following the letter of the law; compliance with the spirit of the law shall be each Covered Person’s goal. In connection with issues concerning such compliance, each Covered Person may consult with appropriate legal counsel or other outside advisors (such as the Company’s independent auditors) on such questions as he or she deems appropriate.

REPORTING OF VIOLATIONS OF THE CODE

Each Covered Person shall comply with the following guidelines, including promptly reporting any violations of this Code of Ethics in accordance with the procedures set forth below:

1. Once a year, each Covered Person shall certify to the Board of Directors that he or she has followed this Code of Ethics and knows of no deviations from such Code by any other Covered Person, or shall give specific details of any such deviation.

2. Covered Persons shall disclose to the Chairman of the Audit Committee, the Chairman of the Board of Directors and the Company’s General Counsel any matter in which they are or may become involved, which in their opinion violates, may violate, or even appear to violate the intent of the Code of Ethics.

3. In addition to the disclosures set forth in the immediately preceding paragraph, all Covered Persons shall promptly report violations of this Code of Ethics by other Covered Persons of which they have knowledge to the Chairman of the Audit Committee, the Chairman of the Board of Directors and the Company’s General Counsel. The Company will not retaliate, and will ensure that no employee retaliates, for any report made hereunder in good faith.

3

ACCOUNTABILITY FOR ADHERENCE TO THE CODE

Atlas and its Board of Directors expect that each of the Covered Persons will comply with all of the terms of this Code of Ethics. The Board of Directors shall determine what, if any, consequences should result from a violation of this Code of Ethics by any Covered Person. Such consequences may include a reduction in compensation, a reassignment of responsibilities, a loss of such Covered Person’s current office or dismissal from the Company. In making its determination, the Board of Directors may take into account all relevant factors, including the type and severity of violation.

AMENDMENTS AND WAIVERS OF THE CODE

Amendments and waivers of this Code of Ethics shall be subject to the following guidelines:

1. An amendment of this Code of Ethics may be made at any time by the Board of Directors of Atlas. The Company’s General Counsel shall be immediately notified of any such amendment.

2. A grant of a waiver of the provisions of this Code of Ethics to any particular Covered Person may only be made by the Board of Directors. The Company’s General Counsel shall be immediately notified of any such waiver.

3. If a Covered Person believes that application of this Code of Ethics would be inappropriate or detrimental to the Company in a particular instance, a request for an exception may be made to the Chairman of the Audit Committee.

4. Atlas shall make a public disclosure of any such amendment to, or waiver of, this Code of Ethics by posting such information on the Company website within four business days of the date of amendment or waiver, provided that the Company shall have disclosed in its most recently filed annual report its Internet address and intention to provide the required disclosure in this manner. Any information so posted must remain on the Company website for at least 12 months. As an alternative, Atlas may make public disclosure of any such amendment or waiver by filing a Report on Form 8-K with the SEC within four business days of the amendment or waiver.

Basis Of Presentation

1. Basis of Presentation

Our consolidated financial statements include the accounts of the holding company, Atlas Air Worldwide Holdings, Inc. (“AAWW”), and its consolidated subsidiaries. AAWW is the parent company of Atlas Air, Inc. (“Atlas”) and Southern Air Holdings, Inc. (“Southern Air”). Southern Air was acquired on April 7, 2016 (see Note 4). AAWW is also the parent company of several subsidiaries related to our dry leasing services (collectively referred to as “Titan”). AAWW has a 51% equity interest and 75% voting interest in Polar Air Cargo Worldwide, Inc. (“Polar”). We record our share of Polar’s results under the equity method of accounting.

Noncontrolling interests represents the interest not owned by us and is recorded for consolidated entities in which we own less than 100% of the interest. Intercompany accounts and transactions have been eliminated. We account for investments in entities under the equity method of accounting when we hold between 20% and 50% ownership in the entity and exercise significant influence or when we are not the primary beneficiary of a variable interest entity. The terms “we,” “us,” “our,” and the “Company” mean AAWW and all entities included in its consolidated financial statements.

We provide outsourced aircraft and aviation operating services throughout the world, serving Africa, Asia, Australia, Europe, the Middle East, North America and South America through: (i) contractual service arrangements, including those through which we provide aircraft to customers and value-added services, including crew, maintenance and insurance (“ACMI”), as well as those through which we provide crew, maintenance and insurance, but not the aircraft (“CMI”); (ii) cargo and passenger charter services (“Charter”); and (iii) dry leasing aircraft and engines (“Dry Leasing” or “Dry Lease”).

Summary of Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires us to make estimates and judgments that affect the amounts reported in these financial statements and the related disclosures. Actual results may differ from those estimates. Estimates are used in determining, among other items, asset lives and residual values, cash flows for impairment analysis, heavy maintenance costs, income tax accounting, business combinations, intangible assets, warrants, contingent liabilities (including, but not limited to litigation accruals), valuation allowances (including, but not limited to, those related to receivables, expendable parts inventory and deferred taxes), stock-based compensation and self-insurance employee benefit accruals.

Revenue Recognition

Revenue from ACMI and CMI contracts is typically recognized as the block hours are operated on behalf of a customer during a given month, as defined contractually, based on flight departure. The time interval between when an aircraft departs the terminal until it arrives at the destination terminal is measured in hours and called a “Block Hour”. If a customer flies below a minimum contracted Block Hour guarantee, the contracted minimum revenue amounts are recognized as revenue. We recognize revenue for Charter upon flight departure.

We record Dry Lease rental income on a straight-line basis over the term of the operating lease. In limited cases, leases provide for additional rentals based on usage, which is recorded as revenue as it is earned under the terms of the lease. Usage is calculated based on hourly usage or number of flights operated, depending on the lease agreement, and is typically reported monthly by the lessee.Rentals received but unearned under the lease agreements are recorded in deferred revenue and included in Accrued liabilities until earned.

Customer maintenance reserves are amounts received under our Dry Leases that are subject to reimbursement to the lessee upon the completion of qualifying maintenance work on the specific Dry Leased aircraft and are included in Accrued liabilities. We defer revenue recognition until the end of the lease, when we are able to finalize the amount, if any, to be reimbursed to the customer.

The Company recognizes revenue for management and administrative support services when the services are provided.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand, demand deposits and other cash investments that are highly liquid in nature and have original maturities of three months or less at acquisition.

Short-term Investments

Short-term investments are primarily comprised of certificates of deposit, current portions of debt securities and money market funds.

Restricted Cash

Cash that is restricted under secured aircraft debt agreements, whereby it can only be used to make principal and interest payments on the related debt secured by those aircraft, is classified as Restricted cash.

Accounts Receivable

We perform a monthly evaluation of our accounts receivable and establish an allowance for doubtful accounts based on our best estimate of probable credit losses resulting from the inability or unwillingness of our customers to make required payments. Account balances are charged off against the allowance when we determine that the receivable will not be recovered.

Escrow Deposits and Letters of Credit

We had $5.0 million as of December 31, 2016and $3.9 million as of December 31, 2015, for certain deposits required in the normal course of business for various items including, but not limited to, surety and customs bonds, airfield privileges, judicial deposits, insurance and cash pledged under standby letters of credit related to collateral. These amounts are included in Deposits and other assets.

Expendable Parts

Expendable parts, materials and supplies for flight equipment are carried at average acquisition costs and are included in Prepaid expenses and other current assets. When used in operations, they are charged to maintenance expense. Allowances for excess and obsolescence for expendable parts expected to be on hand at the date aircraft are retired from service are provided over the estimated useful lives of the related airframes and engines. These allowances are based on management estimates, which are subject to change as conditions in the business evolve. The net book value of expendable parts inventory was $24.2 million as of December 31, 2016and $18.1 million at December 31, 2015, net of allowances for obsolescence of $22.3 million at December 31, 2016and $19.7 million at December 31, 2015.

Property and Equipment

We record property and equipment at cost and depreciate these assets to their estimated residual values on a straight-line basis over their estimated useful lives or average remaining fleet lives. We review these assumptions at least annually and adjust depreciation on a prospective basis. Expenditures for major additions, improvements and flight equipment modifications are generally capitalized and depreciated over the shorter of the estimated life of the improvement, the modified assets’ remaining life or remaining lease term. Most of our flight equipment is specifically pledged as collateral for our indebtedness. The estimated useful lives of our property and equipment are as follows:

	Range
Flight equipment	3 to 40 years
Computer software and equipment	3 to 5 years
Ground handling equipment and other	3 to 5 years

Depreciation expense related to property and equipment was $141.5 million in 2016, $122.2 million in 2015 and $114.0 million in 2014.

The net book value of flight equipment on dry lease to customers was $936.0 million as of December 31, 2016 and $887.9 million as of December 31, 2015. The accumulated depreciation for flight equipment on dry lease to customers was $99.8 million as of December 31, 2016 and $64.5 million as of December 31, 2015.

Rotable parts are recorded in Property and equipment, net, and are depreciated over their average remaining fleet lives and written off when they are determined to be beyond economic repair. The net book value of rotable parts inventory was $142.7 million as of December 31, 2016 and $125.6 million as of December 31, 2015.

Capitalized Interest on Flight Equipment Modifications in Progress

Interest on funds used to finance the acquisition of flight equipment up to the date the asset is ready for its intended use is capitalized and included in the cost of the asset. Included in capitalized interest is the interest paid on the purchase deposit borrowings directly associated with the acquisition of flight equipment. The remainder of capitalized interest recorded on the acquisition of flight equipment is determined by taking the weighted average cost of funds associated with our other debt and applying it against the amounts paid as purchase deposits.

Goodwill

Goodwill represents the excess of an acquisition’s purchase price over the fair value of the identifiable net assets acquired and liabilities assumed. Goodwill is not amortized, but tested for impairment annually during the fourth quarter of each year, or more frequently if certain events or circumstances indicate that an impairment loss may have been incurred.

We may elect to perform a qualitative analysis on the reporting unit that has goodwill to determine whether it is more likely than not that fair value of the reporting unit is less than its carrying value. If the qualitative analysis indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if we elect not to perform a qualitative analysis, we perform a quantitative analysis to determine whether a goodwill impairment exists. If the goodwill’s carrying value exceeds its fair value calculated using the quantitative approach, an impairment charge is recorded for the difference in fair value and carrying value.

Fair value is determined using a discounted cash flow analysis based on key assumptions including, but not limited to, (i) a projection of revenues, expenses and other cash flows; (ii) terminal period revenue growth and cash flows; and (iii) an assumed discount rate.

The total amount of goodwill was $40.4 million, which is included in Intangible assets, net and goodwill, and Prepaid expense and other current assets in the consolidated balance sheetsas of December 31, 2016(see Notes 4 and 6). During the fourth quarter of 2016, we performed a quantitative analysis and determined that goodwill was not impaired.

Impairment of Long-Lived Assets

We record impairment charges on long-lived assets when events and circumstancesindicate that the assets may be impaired, the undiscounted cash flows estimated to be generated by those assets are less than the associated carrying amount and the net book value of the assets exceeds the associated estimated fair value.

For flight equipment and finite-lived intangibles used in our ACMI and Charter segments, assets are grouped at the operating fleet level for impairment testing. For flight equipment and finite-lived intangibles used in our Dry Leasing segment, assets are tested on an individual basis for impairment.

For assets classified as held for sale, an impairment is recognized when the fair value less the cost to sell the asset is less than its carrying amount.

In developing estimates for flight equipment and cash flows, we use external appraisals and other industry data for the various equipment types, anticipated utilization of the assets,revenue generated, associated costs and length of service.

Long-term Investments

Long-term investments consist of debt securities, including accrued interest, for which management has the intent and ability to hold to maturity. These investments are classified as held-to-maturity and are reported at amortized cost. Interest on debt securities and accretion of discounts using the effective interest method are included in Interest income.

Variable Interest Entities and Off-Balance Sheet Arrangements

We hold a 50% interest in GATS GP (BVI) Ltd. (“GATS”), a joint venture with an unrelated third party. The purpose of the joint venture is to purchase rotable parts and provide repair services for those parts, primarily for our 747-8F aircraft. The joint venture is a variable interest entity and we have not consolidated GATS because we are not the primary beneficiary as we do not exercise financial control. Our investment in GATS was $22.2 million as of December 31, 2016 and $20.7 million as of December 31, 2015 and our maximum exposure to losses from the entity is limited to our investment, which is composed primarily of rotable inventory parts. GATS does not have any third-party debt obligations. We had Accounts payable to GATS of $2.4million as of December 31, 2016 and $2.3million as of December 31, 2015.

A portion of our operating aircraft are owned or effectively owned and leased through trusts established specifically to purchase, finance and lease aircraft to us. We have not consolidated any aircraft in the related trusts because we are not the primary beneficiary. Our maximum exposure under these operating leases is the remaining lease payments, which amounts are reflected in the future lease commitments more fully described in Note 10.

Income Taxes

Deferred income taxes are recognized for the tax consequences of reporting items in our income tax returns at different times than the items are reflected in our financial statements. These temporary differences result in deferred tax assets and liabilities that are calculated by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. If necessary, deferred income tax assets are reduced by a valuation allowance to an amount that is determined to be more likely than not recoverable. We must make significant estimates and assumptions about future taxable income and future tax consequences when determining the amount, if any, of the valuation allowance.

We have recorded reserves for income taxes that may become payable in future years. Although management believes that its positions taken on income tax matters are reasonable, we have nevertheless established tax reserves in recognition that various taxing authorities may challenge certain of the positions taken by us, potentially resulting in additional liabilities for taxes.

Heavy Maintenance

Except for engines used on our 747-8F aircraft, we account for heavy maintenance costs for airframes and engines used in our ACMI and Charter segments using the direct expense method. Under this method, heavy maintenance costs are charged to expense upon induction, based on our best estimate of the costs.

We account for heavy maintenance costs for airframes and engines used in our Dry Leasing segment and engines used on our 747-8F aircraft using the deferral method. Under this method, we defer the expense recognition of scheduled heavy maintenance events, which are amortized over the estimated period until the next scheduled heavy maintenance event is required. As ofDecember 31, 2016 and December 31, 2015, deferred maintenance, net was $19.1 million and zero, respectively, which was included within Deferred costs and other assets. During 2016, we deferred maintenance costs of $19.6 million and recorded deferred maintenance amortization expense of $0.5 million included in depreciation and amortization expense.

Prepaid Maintenance Deposits

Certain of our aircraft financing agreements require security deposits to our finance providers to ensure that we perform major maintenance as required. These are substantially refundable to us and are, therefore, accounted for as deposits and included in Prepaid maintenance and in Deferred costs and other assets. Such amountswere $53.4 million as of December 31, 2016 and $47.2 million atDecember 31, 2015.

Foreign Currency

While most of our revenues are denominated in U.S. dollars, our results of operations may be exposed to the effect of fluctuations in the U.S. dollar value of foreign currency-denominated operating revenues and expenses. Our largest exposures come from the Brazilian real. We do not currently have a foreign currency hedging program related to our foreign currency-denominated transactions. Gains or losses resulting from foreign currency transactions are included within Non-operating expenses (income).

Stock-Based Compensation

We have various stock-based compensation plans for certain employees and outside directors, which are described more fully in Note 15. We recognizecompensation expense, net of estimated forfeitures, on a straight-line basis over the vesting period for each awardbased on the fair value on grant date. We estimate grant date fair value for all option grants using the Black-Scholes-Merton option pricing model. We estimate option and restricted stock unit forfeitures at the time of grant and periodically revise those estimates in subsequent periods if actual forfeitures differ from those estimates. As a result, we record stock-based compensation expense only for those awards that are expected to vest.

Legal and Regulatory Matters

We are party to legal and regulatory proceedings with respect to a variety of matters. We evaluate the likelihood of an unfavorable outcome of these proceedings each quarter. Our judgments are subjective and are based on the status of the legal or regulatory proceedings, the merits of our defenses and consultation with legal counsel. Due to the inherent uncertainties of the legal and regulatory proceedings in the multiple jurisdictions in which we operate, our judgments may be different from the actual outcomes.

Supplemental Cash Flow Information

Cash interest paid to lenders is calculated on the face amount of our various debt instruments based on the contractual interest rates in effect during each payment period.

The following table summarizes interest and income taxes paid:

	2016		2015		2014
Interest paid	$	66,306	$	75,135	$	84,265
Income taxes paid, net of refunds	$	1,160	$	(228)	$	1,181

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balance sheets that sum to the total of the same such amounts shown in the consolidated statements of cash flows:

	2016		2015
Cash and cash equivalents	$	123,890	$	425,950
Restricted cash		14,360		12,981
Total cash, cash equivalents and restricted cash
shown in consolidated statements of cash flows	$	138,250	$	438,931

Recent Accounting Pronouncements

In November 2016, the Financial Accounting Standards Board (“FASB”) amended its accounting guidance for statements of cash flows. Under the amended guidance, restricted cash should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period amounts shown on the statement of cash flows. We early adopted this guidance retrospectively effective December 31, 2016 and its adoption did not have a material impact on our financial condition, results of operations or cash flows. The amount of restricted cash reclassified to the end-of-period amounts in our statement of cash flows were $13.0 million and $14.3 million as of December 31, 2015 and 2014, respectively.As a result, net cash used for investing activities increased by $1.3 million and decreased by $7.8 million for the years ended December 31, 2015 and 2014, respectively.

In March 2016, the FASB amended its accounting guidance for share-based compensation. The amended guidance changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. This amended guidance is effective as of the beginning of 2017, with early adoption permitted. We adopted this guidance on January 1, 2017. Upon adoption of this amended guidance, the excess tax benefit associated with share-based compensation, which is currently recognized within equity, will be reflected within income tax expense (benefit) in our consolidated statements of operations. Additionally, our consolidated statements of cash flows will present such excess tax benefit, which is currently presented as a financing activity, as an operating activity. The adoption of this amended guidance is not expected to have a material impact on our financial condition, results of operations or cash flows.

In February 2016, the FASB amended its accounting guidance for leases. The guidance requires a lessee to recognize assets and liabilities on the balance sheet arising from leases with terms greater than twelve months. While lessor accounting guidance is relatively unchanged, certain amendments were made to conform with changes made to lessee accounting and recently released revenue recognition guidance. The new guidance will continue to classify leases as either finance or operating, with classification affecting the pattern of expense and income recognition in the statement of operations. It also requires additional quantitative and qualitative disclosures about leasing arrangements. The amended guidance is effective as of the beginning of 2019, with early adoption permitted. While we are still assessing the impact the amended guidance will have on our financial statements, we expect that recognizing the right-of-use asset and related lease liability will significantly impact our balance sheet. We have developed and are implementing a plan for adopting this amended guidance.

In May 2014, the FASB amended its accounting guidance for revenue recognition. Subsequently, the FASB has issued several clarifications and updates. The fundamental principles of the new guidance are that companies should recognize revenue in a manner that reflects the timing of the transfer of services to customers and consideration that a company expects to receive for the services provided. It also requires additional disclosures necessary for the financial statement users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB deferred the effective date by one year to the beginning of 2018, with early adoption permitted. We plan to adopt this guidance on its required effective date. While we are still assessing the methods of adoption and impact the amended guidance will have on our financial statements, we expect that an immaterial amount of revenue currently recognized based on flight departure will likely be recognized over time as the services are performed. In addition, we expect that revenue related to contracted minimum block hour guarantees under certain ACMI and CMI contracts will likely be recognized in later periods under the amended guidance. We have developed and are implementing a plan for adopting this amended guidance.

DHL Network Operations (USA), Inc. (“DHL”), a subsidiary of Deutsche Post AG (“DP”), holds a 49% equity interest and a 25% voting interest in Polar. Polar is a variable interest entity and we do not consolidate Polar because we are not the primary beneficiary as the risks associated with the direct costs of operation are with DHL. Under a 20-year blocked space agreement, which began in 2008(the “BSA”), Polar provides air cargo capacity to DHL. Atlas and Polar also have a flight services agreement, whereby Atlas is compensated by Polar on a per Block Hour basis, subject to a monthly minimum Block Hour guarantee, at a predetermined rate with the opportunity for performance premiums that escalate annually. Under the flight services agreement, Atlas provides Polar with crew, maintenance and insurance for the aircraft. Under other separate agreements, we provide aircraft to Polar, and Atlas and Polar supply administrative, sales and ground support services to one another. DP has guaranteed DHL’s (and Polar’s) obligations under the various transaction agreements described above. AAWW has agreed to indemnify DHL for and against various obligations of Polar and its affiliates. Collectively, these agreements are referred to herein as the “DHL Agreements”. The DHL Agreements provide us with a minimum guaranteed revenue stream from aircraft that have been dedicated to Polar for DHL and other customers’ freight over the life of the agreements. DHL provides financial support and also assumes the risks and rewards of the operations of Polar.

In accordance with the DHL Agreements, Polar flies for DHL’s transpacific express network and DHL provides financial support and assumes the risks and rewards of the operations of Polar. In addition to transpacific routes, Polar also flies between the Asia Pacific region, the Middle East and Europe on behalf of DHL and other customers.

The BSA established DHL’s capacity purchase commitments on Polar flights. DHL has the right to terminate the 20-year BSA at the twelfth and fifteenth anniversaries of commencement, which was October 27, 2008. Either party may terminate for cause (as defined) at any time. With respect to DHL, “cause” includes Polar’s inability to meet certain departure and arrival criteria for an extended period of time and upon certain change-of-control events, in which case DHL may be entitled to liquidated damages from Polar. Except for any liquidated damages that we could incur as described above, we do not have any continuing financial exposure to fund debt obligations or operating losses of Polar.

Combined with Polar, we provide ACMI, CMI, Charter and Dry Leasing services to support DHL’s transpacific express, North American and intra-Asian networks. In addition, we fly between the Asia Pacific region, the Middle East and Europe on behalf of DHL and other customers. Atlas also provides incremental charter capacity to Polar and DHL on an ad hoc basis.

The following table summarizes the aircraft types, services and number of aircraft provided to DHL as of December 31, 2016:

Business Combinations [Abstract]

Southern Air Acquisition

4. Southern Air Acquisition

On January 15, 2016, we entered into an Agreement and Plan of Merger to acquire all the outstanding shares of Southern Air (the “Southern Air Acquisition”). Southern Air is the parent company of several subsidiaries, including Southern Air Inc. and Florida West International Airways, Inc. (“Florida West”).The Southern Air Acquisition provided us with immediate entry into 777 and 737 aircraft operating platforms, with the potential for developing additional business with existing and new customers of both companies. We believe the platforms provided by these aircraft will augment our ability to offer customers the broadest array of aircraft and operating services for domestic, regional and international applications. Southern Air currently flies five 777-200LRF and five 737-400F aircraft under CMI agreements for DHL.

The Southern Air Acquisition was completed on April 7, 2016. Total consideration of $105.8 million, net of cash acquired, consisted of the following:

Fair value of consideration
Cash paid, net of $15,615 cash acquired		$	107,498
Working capital adjustment			(2,106)
Other adjustments			372
	Total consideration	$	105,764

Tangible and identifiable intangible assets acquired and liabilities assumed were recorded at fair value as of the acquisition date. During 2016, we made certain measurement-period adjustments, including the finalization of the fair value of Florida West, and working capital and other adjustments, that resulted in a net increase to goodwill of $4.0 million.

The following table summarizes the preliminary amounts recognized for fair values of the assets acquired and liabilities assumed:

		Estimated Fair Value
Accounts receivable, net		$	22,912
Prepaid expenses and other current assets			2,434
Property and equipment			6,355
Intangible assets and goodwill			67,341
Deferred income taxes, net			36,452
Other assets			1,498
	Total assets acquired	$	136,992
Accounts payable and accrued liabilities		$	31,228
Total liabilities assumed			31,228
	Net assets acquired	$	105,764

The fair values and useful lives assigned to all intangible assets and goodwill are as follows:

	Estimated Useful Lives	Estimated Fair Value
Customer relationship	16 years	$	26,280
Trade name	1.5 years		700
Goodwill	Indefinite		40,361
Total intangible assets and goodwill		$	67,341

Customer relationship represents the underlying relationship and agreements with DHL. The trade name relates to the Southern Air brand. Goodwill is not deductible for tax purposes and is primarily attributable to the expanded market opportunities expected from combining the service offerings of Southern Air with ours, as well as the employee work force acquired. Southern Air’s results of operations and goodwill are reflected in our ACMI segment.Amortization expense related to Southern Air’s intangible assets amounted to $1.6 million in 2016.

For 2016, our consolidated results include Southern Air’s operating revenue of $79.8 million.For 2016, we incurred Transaction-related expenses of $17.7 million, primarily related to: certain compensation costs, including employee termination benefits; professional fees; and integration costs associated with the acquisition.

A summary of the employee termination benefit liability, which is expected to be paid by the first quarter of 2018, is as follows:

	Employee Termination Benefits
Transaction-related expenses	$	3,797
Cash payments		(2,583)
Liability as of December 31, 2016	$	1,214

The unaudited pro forma operating revenue for 2016 and 2015 was $1,866.7 million and $1,912.4 million, respectively. This pro forma information has been calculated as if the acquisition had taken place on January 1, 2015 and is not necessarily indicative of the net sales that actually would have been achieved. This information includes adjustments to conform with our accounting policies. The earnings of Southern Air were not material and, accordingly, pro forma and actual earnings information have not been presented.

As part of integrating Southern Air, management decided and committed to pursue a plan to sell Florida West. As a result, the financial results for Florida West are presented as a discontinued operation and the assets and liabilities of Florida West are classified as held for sale, since the date of acquisition through December 31, 2016. The aggregate carrying value of Florida West’s assets held for sale was insignificant atDecember 31, 2016 and was included in Prepaid expenses and other current assets. In February 2017, management determined that a sale was no longer likely to occur and committed to a plan to wind down the Florida West operations. The wind-down of operations is expected to be completed during the first quarter of 2017.

During 2016 and 2015, we recognized $10.1 million of impairment losses for six CF6-80 engines classified as held for sale and $8.3 million for five CF6-80 engines classified as held for sale, respectively. Depreciation ceased on the engines. Nine engines were traded in during 2016. The carrying value of two CF6-80 engines held for sale at December 31, 2016was $2.8 million andfive CF6-80 engines held for sale at December 31, 2015 was $7.7 million, which were included within Prepaid expenses and other current assets in the consolidated balance sheets. Two remaining CF6-80 enginesclassified as held for sale are expected to be sold during 2017.

During 2015,we recognized a charge of $7.7 million related to the early termination of high-rate operating leases for two CF6-80 engines.

Goodwill is primarily attributable to the expanded market opportunities expected from combining the service offerings of Southern Air with ours, as well as the employee work force acquired. Fair value adjustments on operating leases represent the capitalized discount recorded in prior years to adjust the lease commitments for our 747-400 aircraft to fair market valueand are amortized on a straight-line basis over the life of the leases. Lease intangibles resulted from the acquisition of various aircraft with in-place Dry Leases to customers on a long-term basisand are amortized on a straight-line basis over the life of the leases. Customer relationship represents Southern Air’s underlying relationship and agreements with DHL. The trade name relates to the Southern Air brand.

Amortization expense related to intangible assets amounted to $9.8 million in 2016, $8.9 million in 2015 and $9.4 million in 2014.

Warrant abstract

Amazon Warrant

7. Amazon

In May 2016, we entered into certain agreements with Amazon.com, Inc. and its subsidiary, Amazon Fulfillment Services, Inc., (collectively “Amazon”), which will involve, among other things, CMI operation of 20 Boeing 767-300 freighter aircraft for Amazon by Atlas, as well as Dry Leasing by Titan. The Dry Leases will have a term of ten years, while the CMI operations will be for seven years (with an option for Amazon to extend the term to a total of ten years). The first aircraft was placed in service during the third quarter of 2016 and the remainder are expected to be placed in service by the end of 2018.

In conjunction with these agreements, 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 $37.50per share. A portion of the warrant, representing the right to purchase 3.75million shares, vested immediately upon issuance of the warrant and the remainder of the warrant, representing the right to purchase 3.75million shares, will vest in increments of 375,000 as the lease and operation of each of the 11^th through 20^th aircraft commences. The warrant will be exercisable in accordance with its terms through 2021. As of December 31, 2016, no warrants have been exercised.

The agreements also provide 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 $37.50per share. This warrant to purchase 3.75million shares will vest in conjunction with payments by Amazon for additional business with us. The warrant will be exercisable in accordance with its terms through 2023.

At a special meeting on September 20, 2016, the Company’s shareholders, by a vote of approximately 99.9% of the votes cast, approved the issuance of warrants to acquire up to 30% of our outstanding common shares. This approval constituted a change in control, as defined under certain of the Company’s benefit plans. As a result, we recognized $23.5million in expense, including accelerated compensation expense for restricted and performance share and cash awards, during 2016 (see Notes 15 and 16). The share-based portion of the compensation expense was $13.3million.

The $92.9 million fair value of the vested portion of the warrant issued to Amazon as of May 4, 2016 was recorded as a warrant liabilitywithin Financial instruments and other liabilities(the “Amazon Warrant”). The initial fair value of the warrant was recognized as a customer incentive asset within Deferred costs and other assets, net and is being amortized as a reduction of revenue in proportion to the amount of revenue recognized over the terms of the Dry Leases and CMI agreements. During 2016, we amortized $0.5 million of the customer incentive asset. The balance of the customer incentive asset, net of amortization,was $92.4 million as of December 31, 2016.

The Amazon Warrant liability is marked-to-market at the end of each reporting period with changes in fair value recorded in Other non-operating expenses.We utilize a Monte Carlo simulation approach to estimate the fair value of the Amazon Warrant which requires inputs such as our common stock price, the warrant strike price, estimated common stock price volatility and risk-free interest rate, among others. We recognized a net unrealized loss of $2.9 million on the Amazon Warrant during 2016. The fair value of the Amazon Warrant liability was $95.8 million as of December 31, 2016.

Description of our Debt Obligations

Ex-Im Bank Guaranteed Notes

We have issued various notes guaranteed by the Export-Import Bank of the United States (“Ex-Im Bank”), each secured by a mortgage on a 747-8F or 777-200LRF aircraft (the “Ex-Im Guaranteed Notes”). In connection with the issuance of Ex-Im Guaranteed Notes, we paid usual and customary commitment and other fees associated with this type of financing. In addition, there are customary covenants, events of default and certain operating conditions that we must meetfor the Ex-Im Guaranteed Notes. These notes accrue interest at a fixed rate with principal and interest payable quarterly.

The following table summarizes the terms and principal balances for each note guaranteed by Ex-Im Bank as of December 31 (in millions):

Term Loans and Capital Lease

We have entered into various term loans to finance the acquisition of aircraft. Each term loan requires payment of principal and interest quarterly in arrears. Funds available under each term loan agreement are subject to usual and customary fees, and funds drawn under the loan agreements typically bear interest at a fixed rate based on LIBOR, plus a margin. Each facility is guaranteed by us and subject to customary covenants and events of default.

In February 2016, we borrowed $14.8 million related to the purchase and conversion of a 767-300BDSF aircraft under an eight-year term loan with a final payment of $3.8 million due in February 2024 (the “First 2016 Term Loan”) secured by a mortgage against the aircraft.

In June 2016, we borrowed $70.0 million under a five-year term loan with a final payment of $30.2 million due in June 2021 (the “Second 2016 Term Loan”). The Second 2016 Term Loan is secured by a mortgage against six spare GEnx engines.

In September 2016, we entered into a capital lease, with an option and the intention to purchase, for a 767-300 passenger aircraft which expires in February 2017.

In December 2016, we borrowed $18.7 million under an unsecured five-year term loan due in October 2021 (the “Third 2016 Term Loan”) for GEnx engine performance upgrade kits and overhauls.

In October 2015, we refinanced two higher-rate term loans, in the aggregate amount of $195.2 million, with a new lower-rate term loan (the “First 2015 Term Loan”) secured by a mortgage against two 747-8F aircraft.

In November 2015, we borrowed $125.0 million under a term loan (the “Second 2015 Term Loan”) secured by a mortgage against a 747-8F aircraft. The Second 2015 Term Loan is cross-collateralized and cross-defaulted with the First 2015 Term Loan.

In December 2015, we borrowed $23.3 million related to the purchase and conversion of a 767-300BDSFaircraft under a term loan (the “Third 2015 Term Loan”) secured by a mortgage against the aircraft.

The following table summarizes the terms and principal balances for each term loan outstanding and the present value of the future minimum lease paymentsas of December 31 (in millions):

Convertible Notes

In June 2015, we issued $224.5 million aggregate principal amount of convertible senior notes (the “Convertible Notes”) in an underwritten public offering. The Convertible Notes are senior unsecured obligations and accrue interest payable semiannually on June 1 and December 1 of each year at a fixed rate of 2.25%. The Convertible Notes will mature on June 1, 2022, unless earlier converted or repurchased pursuant to their terms.

During 2015, we used proceeds from the issuance of the Convertible Notes to refinance higher-rate equipment notes funded by enhanced equipment trust certificates (“EETCs”) related to five 747-400 freighter aircraft owned by us in the aggregate amount of $187.8 million. The EETCs had an average cash coupon of 8.1%. In connection with the refinancing, we recognized a $66.7 million loss on early extinguishment of debt, of which $34.0 million was related to debt extinguishment costs paid to the EETC equipment note holders and $32.7 million was related to the write-off of the debt discount associated with the EETCs. The debt extinguishment costs paid are reflected as a financing activity in the consolidated statements of cash flows. As a result of this refinancing, we recognized a $13.4 million Gain on investments from the early redemption of certain investments related to EETCs in 2015 (see Note 12).

Each $1,000 of principal of the Convertible Notes will initially be convertible into 13.5036 shares of our common stock, which is equal to an initial conversion price of $74.05 per share. The conversion rate will be subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid interest, except in certain limited circumstances. Upon the occurrence of a “make-whole fundamental change,” we will, in certain circumstances, increase the conversion rate by a number of additional shares of our common stock for Convertible Notes converted in connection with such “make-whole fundamental change”. Additionally, if we undergo a “fundamental change,” a holder will have the option to require us to repurchase all or a portion of its Convertible Notes for cash at a price equal to 100% of the principal amount of the Convertible Notes being repurchased plus any accrued and unpaid interest through, but excluding, the fundamental change repurchase date.

In connection with the offering of the Convertible Notes, we entered into convertible note hedge transactions whereby we have the option to purchase initially (subject to adjustment for certain specified events) a total of 3,031,558 shares of our common stock at a price of $74.05 per share. The total cost of the convertible note hedge transactions was $52.9 million. In addition, we sold warrants to the option counterparties whereby the holders of the warrants have the option to purchase initially (subject to adjustment for certain specified events) a total of 3,031,558 shares of our common stock at a price of $95.01. We received $36.3 million in cash proceeds from the sale of these warrants in 2015.

Taken together, the purchase of the convertible note hedges and the sale of warrants are intended to offset any economic dilution from the conversion of the Convertible Notes when the stock price is below $95.01 per share and to effectively increase the overall conversion price from $74.05 to $95.01 per share. However, for purposes of the computation of diluted earnings per share in accordance with GAAP, dilution will occur when the average share price of our common stock for a given period exceeds the conversion price of the Convertible Notes, which initially is equal to $74.05 per share. The $16.6 million net cost incurred in connection with the convertible note hedges and warrants was recorded as a reduction to additional paid-in capital, net of tax, in the consolidated balance sheet.

On or after September 1, 2021 until the close of business on the second scheduled trading day immediately preceding the maturity date, a holder may convert all or a portion of its Convertible Notes.

Upon conversion, the Convertible Notes will be settled, at our election, in cash, shares of our common stock, or a combination of cash and shares of our common stock. Our current intent and policy is to settle conversions with a combination of cash and shares of common stock with the principal amount of the Convertible Notes paid in cash.

Holders may convert their Convertible Notes at their option at any time prior to September 1, 2021, only under the following circumstances:

• during any calendar quarter (and only during such calendar quarter) if, for each of at least 20 trading days (whether or not consecutive) during the 30 consecutive trading day period ending on, and including, the last trading day of the immediately preceding calendar quarter, the last reported sale price of our common stock for such trading day is equal to or greater than 130% of the conversion price on such trading day;

• during the five consecutive business day period immediately following any five consecutive trading day period (the “measurement period”) in which, for each trading day of the measurement period, the trading price per $1,000 principal amount of the Convertible Notes for such trading day was less than 98% of the product of the last reported sale price of our common stock for such trading day and the conversion rate on such trading day; or

• upon the occurrence of specified corporate events.

We separately account for the liability and equity components of the Convertible Notes. The carrying amount of the liability component was determined by measuring the fair value of a similar liability that does not have an associated conversion feature, assuming our nonconvertible unsecured debt borrowing rate. The carrying value of the equity component, the conversion option, which is recognized as additional paid-in-capital, net of tax, creates a debt discount on the Convertible Notes. The debt discount was determined by deducting the relative fair value of the liability component from the proceeds of the Convertible Notes and is amortized to interest expense using an effective interest rate of 6.44% over the term of the Convertible Notes. As of December 31, 2016, the remaining life of the Convertible Notes is 5.4 years. The equity component will not be remeasured as long as it continues to meet the conditions for equity classification.

The Convertible Notes consisted of the following as of December 31:

	2016		2015
Liability component:
Gross proceeds	$	224,500	$	224,500
Less: debt discount, net of amortization		(42,956)		(49,377)
Less: debt issuance cost, net of amortization		(4,146)		(4,823)
Net carrying amount	$	177,398	$	170,300
Equity component (1)	$	52,903	$	52,903
(1) Included in Additional paid-in capital on the consolidated balance sheet as of December 31, 2016 and 2015.

The debt issuance costs related to the issuance of the Convertible Notes were allocated to the liability and equity components based on their relative values, as determined above. Total debt issuance costs were $6.8 million, of which $5.2 million was allocated to the liability component and $1.6 million was allocated to the equity component. The debt issuance costs allocated to the liability component are amortized to interest expense using the effective interest method over the term of the Convertible Notes.

The following table presents the amount of interest expense recognized related to the Convertible Notes:

	For the Years Ended
		December 31, 2016		December 31, 2015
Contractual interest coupon	$	5,051	$	2,919
Amortization of debt discount		6,421		3,526
Amortization of debt issuance costs		677		380
Total interest expense recognized	$	12,149	$	6,825

EETC

In 1999, we issued an EETC secured by a 747-400F aircraft in the amount of $109.9 million for an original term of 20 years with interest rates on the underlying equipment notes ranging from 6.88% to 8.77% and an effective interest rate of 7.52%. The balance outstanding on the leveraged lease was $20.0 million and $28.0 million as of December 31, 2016 and 2015, respectively.

Revolving Credit Facility

In December 2016, we entered into a three-year $150.0 million secured revolving credit facility (the “Revolver”) for general corporate purposes, including financing the acquisition and conversion of 767 aircraft prior to obtaining permanent financing for the converted aircraft. The Revolver is secured by mortgages against nine 747-400 and five 767-300 aircraft, and related engines. Amounts outstanding under the Revolver are subject to borrowing base calculations, collateral coverage and fixed charge ratios. The Revolver accrues interest monthly at LIBOR plus a margin of 2.25% per annum on the amounts outstanding and 0.4% on the undrawn portion. In connection with entry into the Revolver, we paid usual and customary fees. There were no amounts outstanding and we had $150.0 million of unused availability under the Revolver as of December 31, 2016. In January 2017, we drew down $100.0 million under the Revolver.

Leveraged Lease Structure

In three separate transactions in 1998, 1999 and 2000, we issued EETCs to finance the acquisition of five 747-400F aircraft as leveraged leases. In a leveraged lease, the owner trustee is the owner of record for the aircraft. Wells Fargo Bank Northwest, National Association (“Wells Fargo”) serves as the owner trustee with respect to the leveraged leases in each of our EETC transactions. As the owner trustee of the aircraft, Wells Fargo serves as the lessor of the aircraft under the EETC lease between us and the owner trustee. Wells Fargo also serves as trustee for the beneficial owner of the aircraft, the owner participant. The original owner participant for each aircraft invested (on an equity basis) approximately 20% of the original cost of the aircraft. The remaining approximately 80% of the aircraft cost was financed with debt issued by the owner trustee on a nonrecourse basis in the form of equipment notes.

The equipment notes were generally issued in three series, for each aircraft, designated as Series A, B and C equipment notes. The loans evidenced by the equipment notes were funded by the public offering of EETCs. Like the equipment notes, the EETCs were issued in three series, for each EETC transaction designated as Series A, B and C EETCs. Each series of EETCs was issued by the trustee for separate Atlas pass-through trusts with the same designation as the series of EETCs issued (PTCs”). Each of these pass-through trustees is also the holder and beneficial owner of the equipment notes bearing the same series designation.

These leasing entities meet the criteria for variable interest entities. We have not consolidated any of the aircraft-leasing trusts because we are not the primary beneficiary. We account for these leases as operating leases and have included them in our minimum annual rental commitments below.

Operating Leases

The following table summarizes rental expenses in:

		2016		2015		2014
Aircraft and engines	$	146,110	$	145,031	$	140,390
Purchased capacity, office, vehicles and other	$	23,727	$	44,228	$	68,855

As of December 31, 2016, fifteen of our sixty-one operating aircraft were leased, all, except for one, of which were operating leases, with initial lease term expiration dates ranging from 2017 to 2025, with an average remaining lease term of 5.7 years. Certain of our operating leases contain renewal options and escalations. In addition, we lease engines under short-term lease agreements on an as-needed basis. We record rent expense on a straight-line basis over the lease term.

The following table summarizes our minimum annual rental commitments as of the periods indicated under non-cancelable aircraft, engine, real estate and other operating leases with initial or remaining terms of more than one year, reflecting the terms that were in effect as of December 31, 2016:

		Aircraft and Engine		Other

Equipment Purchase Commitments

As of December 31, 2016, our estimated payments remaining for flight equipment purchase commitments are $248.6 million, of which $201.0 million areexpected to be made during 2017.

Guarantees and Indemnifications

In the ordinary course of business, we enter into numerous leasing and financing arrangements for real estate, equipment, aircraft and engines that have various guarantees included in the contracts. These guarantees are primarily in the form of indemnities. In both leasing and financing transactions, we typically indemnify the lessors and any financing parties against tort liabilities that arise out of the use, occupancy, manufacture, design, operation or maintenance of the leased premises or financed aircraft, regardless of whether these liabilities relate to the negligence of the indemnified parties. Currently, we believe that any future payments required under many of these guarantees or indemnities would be immaterial, as most tort liabilities and related indemnities are covered by insurance (subject to deductibles). However, payments under certain tax indemnities related to certain of our financing arrangements, if applicable, could be material, and would not be covered by insurance, although we believe that these payments are not probable. Certain leased premises, such as maintenance and storage facilities, typically include indemnities of such parties for any environmental liability that may arise out of or relate to the use of the leased premises. We also provide standard indemnification agreements to officers and directors in the ordinary course of business.

Financings and Guarantees

Our financing arrangements typically contain a withholding tax provision that requires us to pay additional amounts to the applicable lender or other financing party, if withholding taxes are imposed on such lender or other financing party as a result of a change in the applicable tax law.

These increased costs and withholding tax provisions continue for the entire term of the applicable transaction and there is no limitation on the maximum additional amount we could be required to pay under such provisions. Any failure to pay amounts due under such provisions generally would trigger an event of default and, in a secured financing transaction, would entitle the lender to foreclose upon the collateral to realize the amount due.

Income Taxes

11. Income Taxes

The significant components of the provision for income taxes are as follows:

	2016		2015		2014
Current:
Federal	$	(376)	$	52	$	607
State and local		(298)		48		65
Foreign		84		1,292		(636)
Total current expense		(590)		1,392		36
Deferred:
Federal		46,391		(24,425)		(13,332)
State and local		(1,436)		(3,531)		2,271
Foreign		2,426		2,058		(1,653)
Total deferred expense (benefit)		47,381		(25,898)		(12,714)
Total income tax expense (benefit)	$	46,791	$	(24,506)	$	(12,678)

The domestic and foreign earnings before income taxes are as follows:

	2016		2015		2014
Domestic	$	61,006	$	(57,825)	$	73,386
Foreign		28,410		40,605		16,163
Income (loss) before income taxes	$	89,416	$	(17,220)	$	89,549

A reconciliation of differences between the U.S. federal statutory income tax rate and the effective income tax rates is presented as a percent of expense (benefit) as follows:

	2016	2015	2014
U.S. federal statutory income tax rate	35.0%	(35.0%)	35.0%
State and local taxes based on income, net of federal benefit	1.1%	(2.0%)	2.2%
Change in deferred foreign and state tax rates	(2.2%)	(12.0%)	(4.2%)
Nondeductible customer incentive related to Amazon	10.9%	0.0%	0.0%
Nondeductible compensation expenses related to Amazon	13.0%	0.0%	0.0%
Other nondeductible expenses	4.3%	10.2%	2.2%
Extraterritorial income tax benefit	0.0%	(23.3%)	(38.8%)
Tax incentives and additional deductions	(0.9%)	(4.9%)	(3.8%)
Favorable resolution of income tax issues	0.0%	(13.8%)	(1.5%)
Tax effect of foreign operations	(9.4%)	(66.4%)	(5.7%)
Other	0.5%	4.9%	0.4%
Effective income tax rate	52.3%	(142.3%)	(14.2%)

The effective income tax rate for the twelve months ended December 31, 2016 differed from the U.S. federal statutory rate primarily due to a nondeductible customer incentive and to nondeductible compensation expenses resulting from a change in control, as defined under certain of the Company’s benefit plans, both related to the Amazon transaction (see Note 7). We also generated non-recurring tax benefits from extraterritorial income (“ETI”) in 2015and 2014, which reduced our income tax rate in proportion to our income or loss.

We indefinitely reinvest the net earnings of certain foreign subsidiaries engaged in our Dry Leasing business, which favorably impacted our effective income tax rate for all three years. At December 31, 2016, our undistributed net earnings of foreign subsidiaries for which deferred taxes have not been provided were $103.7 million, and the unrecognized deferred tax liability associated with these earnings was $36.3 million.

Deferred tax assets and liabilities represent the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. The net noncurrent deferred tax asset (liability) was comprised of the following as of December 31:

		Assets (Liabilities)
		2016		2015
Deferred tax assets:
	Net operating loss carryforwards and credits	$	454,749	$	437,408
	Accrued compensation		17,036		16,523
	Accrued legal settlements		25,442		35,909

	Allowance for doubtful accounts		-		1,597
	Goodwill and other intangibles		15,798		-
	Interest rate derivatives		3,124		3,825
	Long-term debt		3,409		3,827
	Obsolescence reserve		7,804		6,723
	Stock-based compensation		6,731		5,385
	Other		686		1,869

	Valuation allowance		(49,396)		(50,711)
	Net deferred tax assets	$	501,492	$	477,218
Deferred tax liabilities:

	Accrued expenses		(10)		(2,166)
	Acquisition of EETC debt		(4,079)		(6,390)
	Deferred maintenance		(6,829)		-
	Incentive related to Amazon		(8,614)		-
	Total deferred tax liabilities	$	(798,437)	$	(762,874)
		Assets (Liabilities)
	Deferred taxes included within following	2016		2015
	balance sheet line items:
	Deferred taxes	$	(298,165)	$	(286,928)
	Deferred costs and other assets		1,219		1,272
	Net deferred tax assets (liabilities)	$	(296,946)	$	(285,656)

As of December 31, 2016 and 2015, we had U.S. federal tax net operating losses (“NOLs”), net of unrecognized tax benefits and valuation allowances, of approximately $991.0 million and $951.6 million, respectively, which will expire through 2036, if not utilized. The increase in NOLs during 2016 resulted primarily from accelerated tax depreciation and from the acquisition of Southern Air (see Note 4). We had alternative minimum tax credits of $4.7 million and $5.2 million as of December 31, 2016 and 2015, respectively, with no expiration date. Additionally, we had foreign NOLs for Hong Kong and Singapore of approximately $463.5 million and $428.8 million as of December 31, 2016 and 2015, respectively,with no expiration date.

Section 382 of the Internal Revenue Code (the “Code”) imposes an annual limitation on the amount of a corporation’s U.S. federal taxable income that can be offset by NOLs if it experiences an “ownership change”, as defined. We experienced ownership changes, as defined, in 2004 and 2009. Accordingly, the use of our NOLs generated prior to these ownership changes is subject to an annual limitation. If certain changes in our ownership occur prospectively, there could be an additional annual limitation on the amount of utilizable carryforwards.

On each reporting date, management assesses whether we are more likely than not to realize some or all of our deferred tax assets. After our assessment, we maintained a valuation allowance of $49.4 million,$50.7 millionand $50.8 million against our deferred tax assets as of December 31, 2016, 2015 and 2014, respectively. We recorded a decrease to the valuation allowance of $1.3million during the year ended December 31, 2016, and decreases of $0.1million and increase of $3.0million during the years ended2015 and 2014, respectively. The valuation allowance is attributable to a limitation on NOL utilization resulting from the ownership change under Section 382. Due to this limitation, we expect a portion of our NOLs generated in 2004 and prior years to eventually expire unused.

A reconciliation of the beginning and ending unrecognized income tax benefits is as follows:

	2016		2015		2014
Beginning balance	$	112,555	$	109,993	$	76,679
Additions for tax positions related to the current year		1,587		551		1,614
Additions for tax positions related to prior years		-		5,503		32,933
Reductions for tax positions related to prior years		(250)		(3,492)		(1,233)
Ending balance	$	113,892	$	112,555	$	109,993

If recognized, all of the unrecognized income tax benefits would favorably impact the effective income tax rate. We will maintain a liability for unrecognized income tax benefits until these uncertain positions are resolved or until the expiration of the applicable statute of limitations, if earlier.

Our policy is to record tax-related interest expense and penalties, if applicable, as a component of income tax expense. We recorded no interest benefit in 2016 or 2015. The cumulative liability for tax-related interest was $0.1 million as of December 31, 2016 and December 31, 2015. We have not recorded any liability for income tax-related penalties, and the tax authorities historically have not assessed any.

For U.S. federal income tax purposes, the 2012 through 2016 income tax years remain subject to examination. We also file income tax returns in multiple states as well as in Hong Kong and Singapore. Generally, the 2012 through 2016 income tax years remain subject to examination in the states where we file. In addition, 2011 through 2016 Singapore income tax yearsand 2010 through 2016 Hong Kong income tax years are subject to examination. No income tax examinations are in process.

12. Financial Instruments

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). Inputs used to measure fair value are classified in the following hierarchy:

Level 1 Unadjusted quoted prices in active markets for identical assets or liabilities;

Level 2 Other inputs that are observable directly or indirectly, such as quoted prices in

active markets for similar assets or liabilities, or inactive quoted prices for identical

assets or liabilities in inactive markets;

Level 3 Unobservable inputs reflecting assumptions about the inputs used in pricing the

asset or liability.

We endeavor to utilize the best available information to measure fair value.

The carrying value of Cash and cash equivalents, Short-term investments and Restricted cash is based on cost, which approximates fair value.

Long-term investments consist of debt securities for which we have both the ability and the intent to hold until maturity. These investments are classified as held-to-maturity and reported at amortized cost. The fair value of our Long-term investments is based on a discounted cash flow analysis using the contractual cash flows of the investments and a discount rate derived from unadjusted quoted interest rates for debt securities of comparable risk. Such debt securities represent investments in PTCs related to EETCs issued by Atlas in 1998, 1999 and 2000.Interest on debt securities and accretion of discounts using the effective interest method are included in Interest income.

The fair value of ourterm loans, notes guaranteed by the Ex-Im Bank and EETCs are based on a discounted cash flow analysis using current borrowing rates for instruments with similar terms.

The fair value of our Convertible Notes is based on unadjusted quoted market prices for these securities.

The fair value of the Amazon Warrant is based on a Monte Carlo simulation which requires inputs such as our common stock price, the warrant strike price, estimated common stock price volatility, and risk-free interest rate, among others.

The following table summarizes the carrying value, estimated fair value and classification of our financial instruments as of:

Our Long-term investments include investments in PTCs related to EETCs. During 2015, we repaid EETCs related to five 747-400 freighter aircraft owned by us using proceeds from the Convertible Notes (see Note 9). Following the refinancing, we recognized a $13.4 million Gain on investments resulting from the early redemption of certain PTCs, of which $5.7 million was related to the receipt of debt redemption premiums and $7.7 million was related to the recognition of deferred income on the PTCs purchased at a discount that have been repaid. The early redemption of PTCs does not impact our ability or intent to hold the remainder of our PTC investments to maturity.

Segment Reporting [Abstract]

Segment Reporting

13. Segment Reporting

Our business is organized into three operating segments based on our service offerings: ACMI, Charter and Dry Leasing. All segments are directly or indirectly engaged in the business of air transportation services but have different commercial and economic characteristics. Each operating segment is separately reviewed by our chief operating decision maker to assess operating results and make resource allocation decisions. We do not aggregate our operating segments and, therefore, our operating segments are our reportable segments.

We use an economic performance metric (“Direct Contribution”) that shows the profitability of each segment after allocation of direct operating and ownership costs. Direct Contribution represents Income (loss) from continuing operations before income taxes excluding the following: Special charges, Transaction-related expenses, nonrecurring items, Losses (gains) on the disposal of aircraft, Losses on early extinguishment of debt, Unrealized losses (gains) on financial instruments, Gains on investments and Unallocated income and expenses, net. Direct operating and ownership costs include crew costs, maintenance, fuel, ground operations, sales costs, aircraft rent, interest expense on the portion of debt used for financing aircraft, interest income on debt securities and aircraft depreciation. Unallocated income and expenses, net include corporate overhead, nonaircraft depreciation, noncash expenses and income, interest expense on the portion of debt used for general corporate purposes, interest income on nondebt securities, capitalized interest, foreign exchange gains and losses, other revenue and other non-operating costs.

Management allocates the costs attributable to aircraft operation and ownership among the various segments based on the aircraft type and activity levels in each segment. Depreciation and amortization expense, aircraft rent, maintenance expense, and other aircraft related expenses are allocated to segments based upon aircraft utilization because certain individual aircraft are utilized across segments interchangeably. In addition, certain ownership costs are directly apportioned to the ACMI segment. Other allocation methods are standard activity-based methods that are commonly used in the industry.

The ACMI segment provides aircraft, crew, maintenance and insurance services to customers. Also included in the ACMI segment is CMI, whereby we provide crew, maintenance and insurance services but not the aircraft. Under ACMI and CMI contracts, customers generally guarantee a monthly level of operation at a predetermined rate for a defined period of time. The customer bears the commercial revenue risk and the obligation for other direct operating costs, including fuel.

The Charter segment provides full-planeload air cargo and passenger aircraft charters to customers, including the U.S. Military Air Mobility Command (the “AMC”), brokers, freight forwarders, direct shippers, airlines, sports teams and fans, and private charter customers. Charter customers generally pay a fixed charter fee and we bear the direct operating costs.

The Dry Leasing segment provides for the leasing of aircraft and engines to customers.

Other represents revenue for services that are not allocated to any segment, including administrative and management support services and flight simulator training.

The following table sets forth Operating Revenue and Direct Contribution for our reportable segments reconciled to Operating Income and Income (loss) from continuing operations before income taxes:

Labor And Legal Proceedings [Abstract]

Labor and Legal Proceedings

14. Labor and Legal Proceedings

Labor

Pilots of Atlas and Southern Air, and flight dispatchers of Atlas and Polar are represented by the International Brotherhood of Teamsters (the “IBT”). We have a five-year collective bargaining agreement (“CBA”) with our Atlas pilots, which became amendable in September 2016 and a four-year CBA with the Southern Air pilots, which became amendable in November 2016. We also have a five-year CBA with our Atlas and Polar dispatchers, which becomes amendable in November 2017.

After we completed the acquisition of Southern Air in April 2016, we informed the IBT of our intention to pursue (and we have been pursuing) a complete operational merger of Atlas and Southern Air. Pursuant to the merger provisions in both the Atlas and Southern Air CBAs, joint negotiations for a single CBA for Atlas and Southern Air should commence promptly. Once a seniority list is presented to us by the unions, it triggers an agreed-upon time frame to negotiate a new joint CBA with any unresolved issues submitted to binding arbitration. After the merger process began, the IBT filed an application for mediation with the National Mediation Board (“NMB”) on behalf of the Atlas pilots. We have opposed the mediation application as it is not in accordance with the merger provisions in the parties’ existing CBAs, which have a defined and streamlined process for negotiating a joint CBA when a merger occurs, as in the case with the Atlas and Southern Air merger. The NMB conducted a pre-mediation investigation in June 2016, which is currently pending. Due to a lack of meaningful progress in such discussions, in February 2017, we filed a lawsuit against the IBT to compel arbitration on the issue of whether the merger provisions in Atlas and Southern Air's CBAs apply to the bargaining process.

We are subject to risks of work interruption or stoppage as permitted by the Railway Labor Act of 1926 (the “Railway Labor Act”) and may incur additional administrative expenses associated with union representation of our employees.

Matters Related to Alleged Pricing Practices

The Company and Polar Air Cargo, LLC (“Old Polar”), a consolidated subsidiary, were named defendants, along with a number of other cargo carriers, in several class actions in the U.S. arising from allegations aboutthe pricing practices of Old Polar and a number of air cargo carriers. These actions were all centralized in the U.S. District Court for the Eastern District of New York. Polar was later joined as an additional defendant. The consolidated complaint alleged, among other things, that the defendants, including the Company and Old Polar, manipulated the market price for air cargo services sold domestically and abroad through the use of surcharges, in violation of U.S., state, and European Union antitrust laws. The suit sought treble damages and attorneys’ fees.

On January 7, 2016, the Company, Old Polar, and Polar entered into a settlement agreement to settle all claims by participating class members against the Company, Old Polar and Polar. The Company, Polar, and Old Polar deny any wrongdoing, and there is no admission of any wrongdoing in the settlement agreement. Pursuant to the settlement agreement, the Company, Old Polar and Polar have agreed to make installment payments over three years to settle the plaintiffs’ claims, with payments of $35.0 million paid on January 15, 2016, $35.0 million due on or before January 15, 2017, and $30.0 million due on or before January 15, 2018. The U.S. District Court for the Eastern District of New York issued an order granting preliminary approval of the settlement on January 12, 2016. On October 6, 2016, the final judgment was issued and the settlement was approved.

In the United Kingdom, several groups of named claimants have brought suit against British Airways in connection with the same alleged pricing practices at issue in the proceedings described above and are seeking damages allegedly arising from that conduct. British Airways has filed claims in the lawsuit against Old Polar and a number of air cargo carriers for contribution should British Airways be found liable to claimants. Old Polar’s formal statement of defense was filed on March 2, 2015. On October 14, 2015, the U.K. Court of Appeal released decisions favorable to the defendant and contributory defendants on two matters under appeal. Permission has been sought to appeal the U.K. Court of Appeal's decisions to the U.K. Supreme Court. In December 2015, certain claimants settled with British Airways removing a significant portion of the claim against British Airways and therefore reducing the potential contribution required by the other airlines, including Old Polar. On December 16, 2015, the European General Court released decisions annulling decisions that the European Commission made against the majority of the air cargo carriers. The European Commission did not appeal the General Court decision, but may still reopen its investigation or reissue a revised decision, either of which would have a significant impact on the proceedings in the U.K. court. Future procedures, including the pretrial disclosure process, are continuing.We are unable to reasonably predict the outcome of the litigation.

In the Netherlands, Stichting Cartel Compensation, successor in interest to claims of various shippers, has filed suit in the district court in Amsterdam against British Airways, KLM, Martinair, Air France, Lufthansa and Singapore Airlines seeking recovery for damages purportedly arising from the same pricing practices at issue in the proceedings described above. In response, British Airways, KLM, Martinair, Air France and Lufthansa filed third-party indemnification lawsuits against Old Polar and Polar seeking indemnification in the event the defendants are found to be liable in the main proceedings. Old Polar and Polar entered their initial court appearances on September 30, 2015. Various procedural issues are undergoing court review.Like the U.K. proceedings, the Netherlands proceedings are likely to be affected by the European Commission’s response to the European General Court decisions of December 16, 2015. We are unable to reasonably predict the outcome of the litigation.

If the Company, Old Polar or Polar were to incur an unfavorable outcome in connection with the U.K. or Netherlands proceedings, such outcome may have a material adverse impact on our business, financial condition, results of operations or cash flows. We are unable to reasonably estimate a range of possible loss for such matters at this time.

Brazilian Customs Claim

Old Polar was cited for two alleged customs violations in Sao Paulo, Brazil, relating to shipments of goods dating back to 1999 and 2000. Each claim asserts that goods listed on the flight manifest of two separate Old Polar scheduled service flights were not on board the aircraft upon arrival and therefore were improperly brought into Brazil. The two claims, which also seek unpaid customs duties, taxes and penalties from the date of the alleged infraction, are approximately $9.3 million in aggregate based on December 31, 2016 exchange rates.

In both cases, we believe that the amounts claimed are substantially overstated due to a calculation error when considering the type and amount of goods allegedly missing, among other things. Furthermore, we may seek appropriate indemnity from the shipper in each claim as may be feasible. In the pending claim for one of the cases, we have received an administrative decision dismissing the claim in its entirety, which remains subject to a mandatory appeal by the Brazil customs authorities. As required to defend such claims, we have made deposits pending resolution of these matters. The balances were $5.0 million as of December 31, 2016 and $3.8 million as of December 31,2015, and are included in Deposits and other assets.

We are currently defending these and other Brazilian customs claims and the ultimate disposition of these claims, either individually or in the aggregate, is not expected to materially affect our financial condition, results of operations or cash flows.

Accruals

As of December 31, 2016, the Company had a remaining accrual of $65.0 million related to the U.S. class action settlement that was recognized in 2015. During 2016, the Company recorded a net accrual of $6.2 million within Other operating expense in the consolidated statement of operations related to pending litigation outside of the U.S.

Other

We have certain other contingencies incident to the ordinary course of business. Management believes that the ultimate disposition of such other contingencies is not expected to materially affect our financial condition, results of operations or cash flows.

Stock-Based Compensation Plans [Abstract]

Stock-Based Compensation Plans

15. Stock-Based and Long-term Incentive Compensation Plans

In 2007, our stockholders approved a Long-Term Incentive Plan (the “2007 Plan”). An aggregate of 0.6 million shares of common stock was reserved for issuance to participants under the 2007 Plan. The 2007 Plan provided for stock awards of up to approximately 2.8 million shares of AAWW’s common stock to employees in various forms, including cash awards and performance cash awards. Stock awards included nonqualified options, incentive stock options, share appreciation rights, restricted shares, restricted share units, performance shares and performance units, dividend equivalents and other share-based awards. In 2016, the stockholders approved a revised Long-Term Incentive Plan (the “2016 Plan”), which replaced the 2007 Plan. An aggregate of 0.7 million shares of common stock was reserved for issuance to participants under the 2016 Plan. No new awards have been made under the 2007 Plan since the adoption of the 2016 Plan in May 2016. Awards outstanding under the 2007 Plan will continue to be governed by the terms of that plan and agreements under which they were granted. The 2016 Plan limits the terms of awards to ten years and prohibits the granting of awards more than ten years after the effective date of the 2016 Plan.

As of December 31, 2016, the 2016 Plan had a total of 0.7 million shares of common stock available for future award grants to management and members of the board of directors. Including the impact of the change in control as defined under the benefit plan in 2016 (see Note 7), our compensation expense for both plans was $30.9 millionin 2016, $15.0 million in 2015and $12.5 million in 2014. Income tax benefits recognized for share-based compensation arrangements were$8.7 million in 2016, $5.7 millionin 2015 and $4.0 millionin 2014. The excess cash tax effect classified as a financing cash inflow was a nominal benefit in 2016, 2015 and 2014.

Nonqualified Stock Options

The portion of the 2016 Plan and the 2007 Plan applicable to employees is administered by the compensation committee of the board of directors, which also establishes the terms of the awards.

Nonqualified stock options, which have not been granted since 2007, vest over a three or four year period and expire seven to ten years from the date of grant. While nonqualified stock options may be granted at any price, they have never been granted with an exercise price less than the fair market value of the stock on the date of grant.

A summary of our options as of December 31, 2016 and changes during the year then ended is presented below:

	Number of Options		Weighted-Average Exercise Price	Weighted-Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value (in thousands)
Outstanding as of December 31, 2015	34,700	$	58.41
Granted	-		-
Exercised	(30,200)		58.34
Forfeited, net of adjustments	-		-
Outstanding as of December 31, 2016	4,500	$	58.89	-	$	-
Exercisable as of December 31, 2016	4,500	$	58.89	-	$	-

The total intrinsic value of options exercised in 2016and 2015was nominal and the cash received waszero and $1.2 million, respectively. No options were exercised in 2014.

As of December 31, 2016, there was no unrecognized compensation cost related to non-vested stock options granted and all options have vested.

Restricted Share Awards

Restricted shares granted vest and are expensed over one-, three- or four- year periods. Restricted share awards have been granted in both shares and units. As of December 31, 2016, a total of 3.5 million restricted shares have been granted under the 2007 and 2016 Plans. All shares were valued at their fair market value on the date of issuance. Unrecognized compensation cost as of December 31, 2016 is $18.9 million and will be recognized over the remaining weighted average life of 2.1years.

A summary of our restricted shares as of December 31, 2016 and changes during the year then ended are presented below:

		Weighted-Average
Restricted Share Awards	Number of Shares	Grant-Date Fair Value
Unvested as of December 31, 2015	840,879	$	40.52
Granted	428,314		36.10
Vested	(522,994)		37.84
Forfeited	(16,053)		38.54
Unvested as of December 31, 2016	730,146	$	39.89

The total fair value of shares vested on various vesting dates was $19.8 million in 2016, $13.7 million in 2015and $11.3 million in 2014. Weighted average grant date fair value was $47.10 in 2015 and $33.21 in 2014.

Performance Share and Performance Cash Awards

Performance share and performance cash awards granted are expensed over three years, which generally is the requisite service period.Awards generally become vested if (1) we achieve certain specified performance levels compared with predetermined performance thresholds during a three-year period starting in the grant year and ending on December 31 three years later, and (2) the employee remains employed by us through the determination date which can be no later than four months following the end of the Performance Period. Partial vesting may occur for certain employee terminations. As a result of a change in control as defined under the benefit plan (see Note 7), the performance levels are deemed to be achieved for all performance share and performance cash awards outstanding as of December 31, 2016. Performance share awards have been granted to employees in shares and units. All performance share and performance cash awards are valued at their fair market value on the date of grant. The estimated compensation expense recognized for performance share and performance cash awards are net of estimated forfeitures. We assess the performance levels in the first quarter of each year for the prior year. We review the results, adjust the estimated performance level and record any change to compensation cost. As of December 31, 2016, a total of 1.7 million performance shares have been granted. Unrecognized compensation cost as of December 31, 2016 is $8.3 million and will be recognized over the remaining weighted average life of 1.7 years. For the performance cash awards, we had accruals of $13.1 million as of December 31, 2016 and $4.0 million as of December 31, 2015 in Other liabilities. Including the impact of the change in control as defined under the benefit plan in 2016, we recognized compensation expense associated with the performance cash awards totaling $13.9 million in 2016, $1.6 million in 2015 and $1.3 million in 2014.

A summary of our performance shares as of December 31, 2016 and changes during the year then ended are presented below:

		Weighted-Average
Performance Share Awards	Number of Shares	Grant-Date Fair Value
Unvested as of December 31, 2015	334,692	$	23.85

Forfeited	(101,701)		47.76
Unvested as of December 31, 2016	576,166	$	27.30

The total fair value of shares vested on various vesting dates in2016 was $5.8 million, $3.7 million in 2015 and $7.0in 2014. Weighted average grant date fair value was $47.48 in 2015 and $32.2in 2014.

Profit Sharing and Incentive Plans

We have an annual incentive compensation program for management employees. The program provides for payments to eligible employees based upon our financial performance, service performance and attainment of individual performance goals, among other things.In addition, our profit sharing plan allows IBT-represented Atlas crewmembers to receive payments from the plan based upon Atlas’ financial performance.The profit sharing plan is subject to a minimum financial performance threshold. For both plans, we had accruals of $22.1 million as of December 31, 2016and $27.0 million as ofDecember 31, 2015 in Accrued liabilities.Including the impact of the change in control as defined under the benefit plan in 2016 (see Note 7), we recognized compensation expense associated with both plans totaling $21.8 million in 2016, $28.5 millionin 2015 and $21.7 million in 2014.

401(k) and 401(m) Plans

Participants in our retirement plan may contribute a portion of their annual compensation to a 401(k) plan on a pretax basis, subject to aggregate limits under the Code. In addition to 401(k) contributions, participants may contribute a portion of their eligible compensation to a 401(m) plan on an after-tax basis. On behalf of participants in the plan who make elective compensation deferrals, we provide a matching contribution subject to certain limitations. Employee contributions in the plan are vested at all times and our matching contributions are subject to a three-year cliff vesting provision, except for employees who are represented by a collective bargaining agreement and are subject to a three-year graded vesting provision. We recognized compensation expense associated with the plan matching contributions totaling $10.5 millionin 2016, $9.5millionin 2015 and $8.5millionin 2014.

Treasury Stock Disclosure

17. Stock Repurchases

We record the repurchase of our shares of common stock at cost based on the settlement date of the transaction. These shares are classified as treasury stock, which is a reduction to stockholders’ equity. Treasury shares are included in authorized and issued shares but excluded from outstanding shares.

In 2008, we established a stock repurchase program authorizing the repurchase of up to $100.0million of our common stock. In November 2013, we announced an increase of $51.0 million to our stock repurchase program. As of December 31, 2016, we had repurchased a total of 3,307,911 shares of our common stock for approximately $126.0 million under this program, resulting in $25.0million of available authorization remaining. Purchases may be made at our discretion in the form of open market repurchase programs, privately negotiated transactions, accelerated share repurchase programs or a combination of these methods. The actual timing and amount of our repurchases will depend on Company and market conditions.

In addition, we repurchased 297,569 and 140,198 shares of common stock from management, in connection with the vesting of equity awards to pay the statutory tax withholdings of employees,at an average price of $37.89 per share in 2016and $46.54 per share in 2015, and held the shares as treasury shares.

18. Earnings Per Share

Basic earnings per share (“EPS”) represent net income divided by the weighted average number of common shares outstanding during the measurement period. Diluted EPS represent net income divided by the weighted average number of common shares outstanding during the measurement period while also giving effect to all potentially dilutive common shares that were outstanding during the period using the treasury stock method. Anti-dilutive shares related to warrants and stock options that were out of the money and excluded for2016 were 3.3 million, 2015 were 3.0 million and were de minimis for 2014.

* Included in the first quarterwas a special charge of $6.6 million. Included in the second quarter were an unrealized gain on financial instruments of $26.5 million, transaction-related expenses of $16.8 million and an accrual for legal matters of $6.7 million. Included in the third quarter were compensation costs related to a change in control as defined under certain benefit plans of $26.2 million, transaction-related expenses of $3.9 million and an unrealized loss on financial instruments of $1.5 million.

** In 2016, the sum of quarterly diluted EPS amounts differs from the full year diluted EPS. The difference primarily relates to the exclusion from the calculation of diluted EPS of an unrealized gain on financial instruments in the second quarter and anti-dilutive shares in the third quarter, both related to the Amazon Warrant.

***Included in the third quarter was a pretax loss on early extinguishment of debt of $66.7 million, a gain on investments of $13.4 million and a special charge of $7.7 million. Included in the fourth quarter was a pretax charge for a legal settlement of $99.8 million included in Other operating expenses (see Note 14), the reclassification of a derivative loss into earnings of $3.7 million, a loss on early extinguishment of debt of $3.0 million and a special charge of $9.8 million.

Summary of Significant Accounting Policies [Abstract]

Use of Estimates Policy

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires us to make estimates and judgments that affect the amounts reported in these financial statements and the related disclosures. Actual results may differ from those estimates. Estimates are used in determining, among other items, asset lives and residual values, cash flows for impairment analysis, heavy maintenance costs, income tax accounting, business combinations, intangible assets, warrants, contingent liabilities (including, but not limited to litigation accruals), valuation allowances (including, but not limited to, those related to receivables, expendable parts inventory and deferred taxes), stock-based compensation and self-insurance employee benefit accruals.

Revenue Recognition Policy

Revenue Recognition

Revenue from ACMI and CMI contracts is typically recognized as the block hours are operated on behalf of a customer during a given month, as defined contractually, based on flight departure. The time interval between when an aircraft departs the terminal until it arrives at the destination terminal is measured in hours and called a “Block Hour”. If a customer flies below a minimum contracted Block Hour guarantee, the contracted minimum revenue amounts are recognized as revenue. We recognize revenue for Charter upon flight departure.

We record Dry Lease rental income on a straight-line basis over the term of the operating lease. In limited cases, leases provide for additional rentals based on usage, which is recorded as revenue as it is earned under the terms of the lease. Usage is calculated based on hourly usage or number of flights operated, depending on the lease agreement, and is typically reported monthly by the lessee.Rentals received but unearned under the lease agreements are recorded in deferred revenue and included in Accrued liabilities until earned.

Customer maintenance reserves are amounts received under our Dry Leases that are subject to reimbursement to the lessee upon the completion of qualifying maintenance work on the specific Dry Leased aircraft and are included in Accrued liabilities. We defer revenue recognition until the end of the lease, when we are able to finalize the amount, if any, to be reimbursed to the customer.

The Company recognizes revenue for management and administrative support services when the services are provided.

Cash and Cash Equivalents Policy

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand, demand deposits and other cash investments that are highly liquid in nature and have original maturities of three months or less at acquisition.

Short-Term Investments Policy

Short-term Investments

Short-term investments are primarily comprised of certificates of deposit, current portions of debt securities and money market funds.

Restricted Cash Policy

Restricted Cash

Cash that is restricted under secured aircraft debt agreements, whereby it can only be used to make principal and interest payments on the related debt secured by those aircraft, is classified as Restricted cash.

Accounts Receivable Policy

Accounts Receivable

We perform a monthly evaluation of our accounts receivable and establish an allowance for doubtful accounts based on our best estimate of probable credit losses resulting from the inability or unwillingness of our customers to make required payments. Account balances are charged off against the allowance when we determine that the receivable will not be recovered.

Escrow Deposits and Letters of Credit Policy

Escrow Deposits and Letters of Credit

We had $5.0 million as of December 31, 2016and $3.9 million as of December 31, 2015, for certain deposits required in the normal course of business for various items including, but not limited to, surety and customs bonds, airfield privileges, judicial deposits, insurance and cash pledged under standby letters of credit related to collateral. These amounts are included in Deposits and other assets.

Expendable Parts Policy

Expendable Parts

Expendable parts, materials and supplies for flight equipment are carried at average acquisition costs and are included in Prepaid expenses and other current assets. When used in operations, they are charged to maintenance expense. Allowances for excess and obsolescence for expendable parts expected to be on hand at the date aircraft are retired from service are provided over the estimated useful lives of the related airframes and engines. These allowances are based on management estimates, which are subject to change as conditions in the business evolve. The net book value of expendable parts inventory was $24.2 million as of December 31, 2016and $18.1 million at December 31, 2015, net of allowances for obsolescence of $22.3 million at December 31, 2016and $19.7 million at December 31, 2015.

Property and Equipment Policy

Property and Equipment

We record property and equipment at cost and depreciate these assets to their estimated residual values on a straight-line basis over their estimated useful lives or average remaining fleet lives. We review these assumptions at least annually and adjust depreciation on a prospective basis. Expenditures for major additions, improvements and flight equipment modifications are generally capitalized and depreciated over the shorter of the estimated life of the improvement, the modified assets’ remaining life or remaining lease term. Most of our flight equipment is specifically pledged as collateral for our indebtedness. The estimated useful lives of our property and equipment are as follows:

	Range
Flight equipment	3 to 40 years
Computer software and equipment	3 to 5 years
Ground handling equipment and other	3 to 5 years

Depreciation expense related to property and equipment was $141.5 million in 2016, $122.2 million in 2015 and $114.0 million in 2014.

The net book value of flight equipment on dry lease to customers was $936.0 million as of December 31, 2016 and $887.9 million as of December 31, 2015. The accumulated depreciation for flight equipment on dry lease to customers was $99.8 million as of December 31, 2016 and $64.5 million as of December 31, 2015.

Rotable parts are recorded in Property and equipment, net, and are depreciated over their average remaining fleet lives and written off when they are determined to be beyond economic repair. The net book value of rotable parts inventory was $142.7 million as of December 31, 2016 and $125.6 million as of December 31, 2015.

Capitalized Interest on Pre-delivery Deposits Policy

Capitalized Interest on Flight Equipment Modifications in Progress

Interest on funds used to finance the acquisition of flight equipment up to the date the asset is ready for its intended use is capitalized and included in the cost of the asset. Included in capitalized interest is the interest paid on the purchase deposit borrowings directly associated with the acquisition of flight equipment. The remainder of capitalized interest recorded on the acquisition of flight equipment is determined by taking the weighted average cost of funds associated with our other debt and applying it against the amounts paid as purchase deposits.

Goodwill Policy

Goodwill

Goodwill represents the excess of an acquisition’s purchase price over the fair value of the identifiable net assets acquired and liabilities assumed. Goodwill is not amortized, but tested for impairment annually during the fourth quarter of each year, or more frequently if certain events or circumstances indicate that an impairment loss may have been incurred.

We may elect to perform a qualitative analysis on the reporting unit that has goodwill to determine whether it is more likely than not that fair value of the reporting unit is less than its carrying value. If the qualitative analysis indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if we elect not to perform a qualitative analysis, we perform a quantitative analysis to determine whether a goodwill impairment exists. If the goodwill’s carrying value exceeds its fair value calculated using the quantitative approach, an impairment charge is recorded for the difference in fair value and carrying value.

Fair value is determined using a discounted cash flow analysis based on key assumptions including, but not limited to, (i) a projection of revenues, expenses and other cash flows; (ii) terminal period revenue growth and cash flows; and (iii) an assumed discount rate.

The total amount of goodwill was $40.4 million, which is included in Intangible assets, net and goodwill, and Prepaid expense and other current assets in the consolidated balance sheetsas of December 31, 2016(see Notes 4 and 6). During the fourth quarter of 2016, we performed a quantitative analysis and determined that goodwill was not impaired.

Impairment of Long-Lived Assets Policy

Impairment of Long-Lived Assets

We record impairment charges on long-lived assets when events and circumstancesindicate that the assets may be impaired, the undiscounted cash flows estimated to be generated by those assets are less than the associated carrying amount and the net book value of the assets exceeds the associated estimated fair value.

For flight equipment and finite-lived intangibles used in our ACMI and Charter segments, assets are grouped at the operating fleet level for impairment testing. For flight equipment and finite-lived intangibles used in our Dry Leasing segment, assets are tested on an individual basis for impairment.

For assets classified as held for sale, an impairment is recognized when the fair value less the cost to sell the asset is less than its carrying amount.

In developing estimates for flight equipment and cash flows, we use external appraisals and other industry data for the various equipment types, anticipated utilization of the assets,revenue generated, associated costs and length of service.

Long Term Investments Policy

Long-term Investments

Long-term investments consist of debt securities, including accrued interest, for which management has the intent and ability to hold to maturity. These investments are classified as held-to-maturity and are reported at amortized cost. Interest on debt securities and accretion of discounts using the effective interest method are included in Interest income.

Variable Interest Entities and Off-Balance-Sheet Arrangements Policy

Variable Interest Entities and Off-Balance Sheet Arrangements

We hold a 50% interest in GATS GP (BVI) Ltd. (“GATS”), a joint venture with an unrelated third party. The purpose of the joint venture is to purchase rotable parts and provide repair services for those parts, primarily for our 747-8F aircraft. The joint venture is a variable interest entity and we have not consolidated GATS because we are not the primary beneficiary as we do not exercise financial control. Our investment in GATS was $22.2 million as of December 31, 2016 and $20.7 million as of December 31, 2015 and our maximum exposure to losses from the entity is limited to our investment, which is composed primarily of rotable inventory parts. GATS does not have any third-party debt obligations. We had Accounts payable to GATS of $2.4million as of December 31, 2016 and $2.3million as of December 31, 2015.

A portion of our operating aircraft are owned or effectively owned and leased through trusts established specifically to purchase, finance and lease aircraft to us. We have not consolidated any aircraft in the related trusts because we are not the primary beneficiary. Our maximum exposure under these operating leases is the remaining lease payments, which amounts are reflected in the future lease commitments more fully described in Note 10.

Income Taxes Policy

Income Taxes

Deferred income taxes are recognized for the tax consequences of reporting items in our income tax returns at different times than the items are reflected in our financial statements. These temporary differences result in deferred tax assets and liabilities that are calculated by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. If necessary, deferred income tax assets are reduced by a valuation allowance to an amount that is determined to be more likely than not recoverable. We must make significant estimates and assumptions about future taxable income and future tax consequences when determining the amount, if any, of the valuation allowance.

We have recorded reserves for income taxes that may become payable in future years. Although management believes that its positions taken on income tax matters are reasonable, we have nevertheless established tax reserves in recognition that various taxing authorities may challenge certain of the positions taken by us, potentially resulting in additional liabilities for taxes.

Heavy Maintenance Policy

Heavy Maintenance

Except for engines used on our 747-8F aircraft, we account for heavy maintenance costs for airframes and engines used in our ACMI and Charter segments using the direct expense method. Under this method, heavy maintenance costs are charged to expense upon induction, based on our best estimate of the costs.

We account for heavy maintenance costs for airframes and engines used in our Dry Leasing segment and engines used on our 747-8F aircraft using the deferral method. Under this method, we defer the expense recognition of scheduled heavy maintenance events, which are amortized over the estimated period until the next scheduled heavy maintenance event is required. As ofDecember 31, 2016 and December 31, 2015, deferred maintenance, net was $19.1 million and zero, respectively, which was included within Deferred costs and other assets. During 2016, we deferred maintenance costs of $19.6 million and recorded deferred maintenance amortization expense of $0.5 million included in depreciation and amortization expense.

Prepaid Maintenance Deposits Policy

Prepaid Maintenance Deposits

Certain of our aircraft financing agreements require security deposits to our finance providers to ensure that we perform major maintenance as required. These are substantially refundable to us and are, therefore, accounted for as deposits and included in Prepaid maintenance and in Deferred costs and other assets. Such amountswere $53.4 million as of December 31, 2016 and $47.2 million atDecember 31, 2015.

Foreign Currency Policy

Foreign Currency

While most of our revenues are denominated in U.S. dollars, our results of operations may be exposed to the effect of fluctuations in the U.S. dollar value of foreign currency-denominated operating revenues and expenses. Our largest exposures come from the Brazilian real. We do not currently have a foreign currency hedging program related to our foreign currency-denominated transactions. Gains or losses resulting from foreign currency transactions are included within Non-operating expenses (income).

Stock-Based Compensation Policy

Stock-Based Compensation

We have various stock-based compensation plans for certain employees and outside directors, which are described more fully in Note 15. We recognizecompensation expense, net of estimated forfeitures, on a straight-line basis over the vesting period for each awardbased on the fair value on grant date. We estimate grant date fair value for all option grants using the Black-Scholes-Merton option pricing model. We estimate option and restricted stock unit forfeitures at the time of grant and periodically revise those estimates in subsequent periods if actual forfeitures differ from those estimates. As a result, we record stock-based compensation expense only for those awards that are expected to vest.

Litigation Accruals Policy

Legal and Regulatory Matters

We are party to legal and regulatory proceedings with respect to a variety of matters. We evaluate the likelihood of an unfavorable outcome of these proceedings each quarter. Our judgments are subjective and are based on the status of the legal or regulatory proceedings, the merits of our defenses and consultation with legal counsel. Due to the inherent uncertainties of the legal and regulatory proceedings in the multiple jurisdictions in which we operate, our judgments may be different from the actual outcomes.

Supplemental Cash Flow Information

Supplemental Cash Flow Information

Cash interest paid to lenders is calculated on the face amount of our various debt instruments based on the contractual interest rates in effect during each payment period.

The following table summarizes interest and income taxes paid:

	2016		2015		2014

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In November 2016, the Financial Accounting Standards Board (“FASB”) amended its accounting guidance for statements of cash flows. Under the amended guidance, restricted cash should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period amounts shown on the statement of cash flows. We early adopted this guidance retrospectively effective December 31, 2016 and its adoption did not have a material impact on our financial condition, results of operations or cash flows. The amount of restricted cash reclassified to the end-of-period amounts in our statement of cash flows were $13.0 million and $14.3 million as of December 31, 2015 and 2014, respectively.As a result, net cash used for investing activities increased by $1.3 million and decreased by $7.8 million for the years ended December 31, 2015 and 2014, respectively.

In March 2016, the FASB amended its accounting guidance for share-based compensation. The amended guidance changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. This amended guidance is effective as of the beginning of 2017, with early adoption permitted. We adopted this guidance on January 1, 2017. Upon adoption of this amended guidance, the excess tax benefit associated with share-based compensation, which is currently recognized within equity, will be reflected within income tax expense (benefit) in our consolidated statements of operations. Additionally, our consolidated statements of cash flows will present such excess tax benefit, which is currently presented as a financing activity, as an operating activity. The adoption of this amended guidance is not expected to have a material impact on our financial condition, results of operations or cash flows.

In February 2016, the FASB amended its accounting guidance for leases. The guidance requires a lessee to recognize assets and liabilities on the balance sheet arising from leases with terms greater than twelve months. While lessor accounting guidance is relatively unchanged, certain amendments were made to conform with changes made to lessee accounting and recently released revenue recognition guidance. The new guidance will continue to classify leases as either finance or operating, with classification affecting the pattern of expense and income recognition in the statement of operations. It also requires additional quantitative and qualitative disclosures about leasing arrangements. The amended guidance is effective as of the beginning of 2019, with early adoption permitted. While we are still assessing the impact the amended guidance will have on our financial statements, we expect that recognizing the right-of-use asset and related lease liability will significantly impact our balance sheet. We have developed and are implementing a plan for adopting this amended guidance.

In May 2014, the FASB amended its accounting guidance for revenue recognition. Subsequently, the FASB has issued several clarifications and updates. The fundamental principles of the new guidance are that companies should recognize revenue in a manner that reflects the timing of the transfer of services to customers and consideration that a company expects to receive for the services provided. It also requires additional disclosures necessary for the financial statement users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB deferred the effective date by one year to the beginning of 2018, with early adoption permitted. We plan to adopt this guidance on its required effective date. While we are still assessing the methods of adoption and impact the amended guidance will have on our financial statements, we expect that an immaterial amount of revenue currently recognized based on flight departure will likely be recognized over time as the services are performed. In addition, we expect that revenue related to contracted minimum block hour guarantees under certain ACMI and CMI contracts will likely be recognized in later periods under the amended guidance. We have developed and are implementing a plan for adopting this amended guidance.
