Item 1.
Business
Company Overview
Southwest Airlines Co. (the “Company” or “Southwest”) operates Southwest Airlines, a major passenger airline that provides scheduled air transportation in the United States and near-international markets. For the 44th consecutive year, the Company was profitable, earning $2.2 billion in net income.
Southwest commenced service on June 18, 1971, with three Boeing 737 aircraft serving three Texas cities: Dallas, Houston, and San Antonio. At December 31, 2016, Southwest operated a total of 723 Boeing 737 aircraft and served 101 destinations in 40 states, the District of Columbia, the Commonwealth of Puerto Rico, and eight near-international countries: Mexico, Jamaica, The Bahamas, Aruba, Dominican Republic, Costa Rica, Belize, and Cuba.
The Company added its first three destinations in Cuba during 2016, with service to Varadero and Santa Clara from Fort Lauderdale-Hollywood International Airport and service to Havana from both Fort Lauderdale and Tampa International Airport. The Company also expanded its domestic footprint during 2016, with the commencement of service at Long Beach Airport, the Company's fifth service point in the L.A. Basin and tenth airport in California.
Based on the most recent data available from the U.S. Department of Transportation (the "DOT"), as of June 30, 2016, Southwest was the largest domestic air carrier in the United States, as measured by the number of domestic originating passengers boarded.
Industry
The airline industry has historically been an extremely volatile industry subject to numerous challenges. Among other things, it has been cyclical, energy intensive, labor intensive, capital intensive, technology intensive, highly regulated, heavily taxed, and extremely competitive. The airline industry has also been particularly susceptible to detrimental events such as acts of terrorism, poor weather, and natural disasters.
The U.S. airline industry benefited from moderate economic growth during 2016 and was further aided by low fuel prices. In recent years, the U.S. airline industry, including Southwest, has increased available seat miles (also referred to as “capacity,” an available seat mile is one seat, empty or full, flown one mile and is a measure of space available to carry passengers in a given period), and has increased the number of seats per trip (or “gauge”) through slimline seat retrofits and the use of larger aircraft.
Company Operations
Route Structure
General
Southwest principally provides point-to-point service, rather than the “hub-and-spoke” service provided by most major U.S. airlines. The hub-and-spoke system concentrates most of an airline’s operations at a limited number of central hub cities and serves most other destinations in the system by providing one-stop or connecting service through a hub. By not concentrating operations through one or more central transfer points, Southwest’s point-to-point route structure has allowed for more direct nonstop routing than hub-and-spoke service. Approximately 76 percent of the Company's Customers flew nonstop during 2016, and, as of December 31, 2016, Southwest served 657 nonstop city pairs.
Southwest’s point-to-point service has also enabled it to provide its markets with frequent, conveniently timed flights and low fares. For example, Southwest currently offers 20 weekday roundtrips between Dallas Love Field and Houston Hobby, 13 weekday roundtrips between Burbank and Oakland, 12 weekday roundtrips between San Diego and San Jose, 10 weekday roundtrips between Denver and Chicago Midway, and eight weekday roundtrips between Phoenix and Las Vegas.
Southwest complements its high-frequency short-haul routes with long-haul nonstop service between markets such as Los Angeles and Nashville, Las Vegas and Orlando, San Diego and Baltimore, Houston and New York LaGuardia, and Oakland and Baltimore. During 2016, the Company continued to incorporate the Boeing 737-800 aircraft into its fleet, which offers significantly more Customer seating capacity than Southwest’s other aircraft. This has enabled the Company to more economically serve long-haul routes, as well as high-demand, slot-controlled, and gate-restricted

4


airports, by adding seats for such routes without increasing the number of flights (a “slot” is the right of an air carrier, pursuant to regulations of the Federal Aviation Administration (“FAA”), to operate a takeoff or landing at a specific time at certain airports). For 2016, the Company’s average aircraft trip stage length was 760 miles, with an average duration of approximately 2.0 hours, as compared with an average aircraft trip stage length of 750 miles and an average duration of approximately 2.0 hours in 2015.
With the addition of Long Beach Airport to the Company’s route map in 2016, the Company added four weekday flights from Long Beach to Oakland, which, in turn, has brought connectivity between Long Beach and 20 cities on the Southwest network across the Pacific Northwest and mid-America. Based on the most recent data available from the DOT, as of June 30, 2016, Southwest offers more seats than any other carrier each day to, from, and within California.
The Company has announced plans to add service, beginning in June 2017, to Cincinnati/Northern Kentucky International Airport and, subject to requisite government approvals, to Owen Roberts International Airport in Grand Cayman. The Company’s addition of service to Cincinnati/Northern Kentucky International Airport, scheduled for June 2017, will give the Company’s Customers access to a full complement of the top 50 markets across the 48 contiguous United States.
International Service
Southwest Airlines launched international service in 2014, ending 2016 with service to 14 international destinations through 13 international gateway cities within the 48 contiguous United States.
During 2016, the Company commenced international service out of Los Angeles International Airport by introducing service to Liberia, Costa Rica, and later to three airports in Mexico’s coastal regions: Cancun, San Jose del Cabo/Los Cabos, and Puerto Vallarta. Also during 2016, the Company began scheduled international service from Fort Lauderdale with daily service to Nassau, Bahamas. The Company has also announced its first ever international service from Oakland International Airport and San Diego International Airport, its 14th and 15th international gateway cities within the 48 contiguous United States, with daily flights from Oakland to San Jose del Cabo/Los Cabos and Puerto Vallarta scheduled to begin in February 2017 and from San Diego to San Jose del Cabo/Los Cabos scheduled to begin in April 2017.
In connection with the scheduled opening of a new five-gate international concourse at Fort Lauderdale-Hollywood International Airport (FLL) in June 2017, the Company has announced a significantly expanded international flight schedule for South Florida to a total of eight international nonstop destinations. In addition to existing service, beginning in June 2017, the Company is scheduled to offer new daily international nonstop service from Fort Lauderdale to Montego Bay, Jamaica; Belize City, Belize; and Cancun, Mexico, and subject to requisite government approvals, Grand Cayman. Additional information regarding the Company’s involvement with construction of the new concourse at FLL is provided below under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and in Note 4 to the Consolidated Financial Statements.
Approximately $383 million, approximately $287 million, and approximately $226 million of the Company’s operating revenues in 2016, 2015, and 2014, respectively, were attributable to foreign operations. The remainder of the Company’s operating revenues, approximately $20.0 billion, approximately $19.5 billion, and approximately $18.4 billion in 2016, 2015, and 2014, respectively, were attributable to domestic operations. The Company's operating revenues in 2014 included the operating revenues of AirTran Airways ("AirTran"). AirTran's final passenger service occurred on December 28, 2014, and it has been integrated into Southwest. The Company's assets are not allocated to a geographic area because the Company’s tangible assets primarily consist of flight equipment, the majority of which are interchangeable and are deployed systemwide, with no individual aircraft dedicated to any specific route or region.
Cost Structure
A key component of the Company’s business strategy is its focus on cost discipline and profitably charging low fares. Adjusted for stage length, the Company has lower unit costs, on average, than the majority of major domestic carriers. The Company’s strategy includes the use of a single aircraft type, the Boeing 737, the Company’s operationally efficient point-to-point route structure, and its highly productive Employees. Southwest’s use of a single aircraft type allows for simplified scheduling, maintenance, flight operations, and training activities. Southwest’s point-to-point route structure includes service to and from many secondary or downtown airports such as Dallas Love Field, Houston Hobby, Chicago Midway, Baltimore-Washington International, Burbank, Manchester, Oakland, San Jose, Providence,

5


and Ft. Lauderdale-Hollywood. These conveniently located airports are typically less congested than other airlines’ hub airports, which has contributed to Southwest's ability to achieve high asset utilization because aircraft can be scheduled to minimize the amount of time they are on the ground. This, in turn, has reduced the number of aircraft and gate facilities that would otherwise be required and allows for high Employee productivity (headcount per aircraft).
The Company’s focus on controlling costs also includes ongoing work to reduce fuel consumption. Although 2016 fuel prices were lower than 2015 fuel prices, Fuel and oil expense remained the Company's second largest operating cost. Furthermore, as evidenced by the table below, energy prices can fluctuate significantly in a relatively short amount of time. The table below shows the Company’s average cost of jet fuel for each year beginning in 2003 and during each quarter of 2016.

The Company focuses on reducing fuel consumption and improving fuel efficiency through fleet modernization and other fuel initiatives. For example, during 2016, the Company continued to replace its older aircraft with newer aircraft that are less maintenance intensive and more fuel efficient. The Company also announced its intent to accelerate the retirement of its 737-300 aircraft to no later than third quarter 2017, when it is scheduled to take delivery of its first, more fuel-efficient, Boeing 737-8 aircraft. The Company's fleet composition and delivery schedules are discussed in more detail below under "Properties - Aircraft." The Company has also undertaken a number of other fuel conservation initiatives which are discussed in detail under “Regulation - Environmental Regulation."
To illustrate the results of the Company’s efforts to reduce fuel consumption, the table below sets forth the Company's available seat miles produced per fuel gallon consumed over the last five years:

The Company also enters into fuel derivative contracts to manage its risk associated with significant increases in fuel prices. The Company’s fuel hedging activities, as well as the risks associated with high and/or volatile fuel prices, are discussed in more detail below under “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and Note 10 to the Consolidated Financial Statements.

Salaries, wages, and benefits expense constituted approximately 41 percent of the Company’s operating expenses during 2016 and was the Company’s largest operating cost. The Company’s ability to control labor costs is limited by the terms of its collective-bargaining agreements, and increased labor costs have negatively impacted the Company’s low-cost competitive position. The Company’s labor costs, and risks associated therewith, are discussed in more detail below under “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”
Fare Structure
General

Southwest offers a relatively simple fare structure that features competitive, unrestricted, unlimited, everyday coach fares, as well as lower fares available on a restricted basis. Southwest bundles fares into three major categories: “Wanna Get Away®,” “AnytimeSM,” and “Business Select®,” with the goal of making it easier for Customers to choose the fare they prefer. All fare products include the privilege of two free checked bags (weight and size limits apply). In addition, regardless of the fare product, Southwest does not charge fees for changes to flight reservations.

•
“Wanna Get Away” fares are generally the lowest fares and are typically subject to advance purchase requirements. They are nonrefundable but, subject to compliance with Southwest’s No Show policy, funds may be applied to future travel on Southwest without a change fee. Southwest’s No Show policy applies if a Customer has booked a nonrefundable fare anywhere in his/her itinerary and that portion of the flight is not used and not canceled or changed by the Customer at least ten minutes prior to scheduled departure. In such event, subject to certain exceptions, all unused funds on the full itinerary will be forfeited, and the remaining reservation will be canceled. The intent of the No Show policy is to promote Customer behavior that will enable Southwest to re-sell the open seat prior to departure.
•
“Anytime” fares are refundable and changeable, and funds may also be applied toward future travel on Southwest. Anytime fares also include a higher frequent flyer point multiplier under Southwest’s Rapid Rewards® frequent flyer program than do Wanna Get Away fares. The Company's frequent flyer program is discussed below under "Rapid Rewards Frequent Flyer Program."
•
“Business Select” fares are refundable and changeable, and funds may be applied toward future travel on Southwest. Business Select fares also include additional perks, when available, such as priority boarding in the first 15 boarding positions within boarding group “A,” a higher frequent flyer point multiplier than other Southwest fares (including twice as many points per dollar spent as compared with Wanna Get Away fares), “Fly By®” priority security and/or ticket counter access in participating airports, and one complimentary adult beverage coupon for the day of travel (for Customers of legal drinking age).
Ancillary Services
The Company offers ancillary service offerings such as Southwest’s EarlyBird Check-In® and transportation of pets and unaccompanied minors, in accordance with Southwest's respective policies. EarlyBird Check-In provides Customers with automatic check-in before general boarding positions become available, improving Customers' seat selection options (priority boarding privileges are already a benefit of being an "A-List" tier member under the Company's Rapid Rewards Frequent Flyer Program). Southwest’s Pet Policy provides Customers an opportunity to bring a small cat or dog into the aircraft cabin. Southwest also has an unaccompanied minor travel policy to address the administrative costs and the extra care necessary to safely transport these Customers.
When available, Southwest also sells, at the airport, open priority boarding positions in the first 15 positions in its "A" boarding group.
Southwest offers inflight satellite-based WiFi service on all of its 737-700 and 737-800 aircraft, representing over 87 percent of Southwest’s fleet. Southwest’s Customers with small portable electronic devices are able to utilize the airline’s onboard WiFi from gate-to-gate when traveling on a Southwest WiFi-enabled aircraft. Southwest was the first carrier to offer gate-to-gate connectivity. Southwest’s onboard entertainment options on WiFi-enabled aircraft for viewing on Customers’ personal wireless devices include free access to Southwest’s live and on-demand television product. The television product currently consists of nearly 20 live channels and up to 75 on-demand recorded episodes from popular television series. Due to licensing restrictions, free live TV may not be available onboard WiFi-enabled

7


international flights. In late 2016, the Company entered into new WiFi connectivity agreements designed to yield greater WiFi bandwidth available to Customers on WiFi-equipped aircraft beginning in mid-2017. By the end of 2017, the Company expects to operate a 100 percent WiFi-equipped fleet. Southwest also provides movies-on-demand, and also offers a Messaging-only option, including all WiFi-enabled stops and connections. The Messaging service allows access to iMessage and pre-downloaded apps for Viber and WhatsApp. Customers do not have to purchase WiFi to access television offerings, movies-on-demand, or the Messaging-only service.
Rapid Rewards Frequent Flyer Program
Southwest’s Rapid Rewards frequent flyer program enables program members (“Members”) to earn points for every dollar spent on Southwest fares. The amount of points earned under the program is based on the fare and fare class purchased, with higher fare products (e.g., Business Select) earning more points than lower fare products (e.g., Wanna Get Away). Each fare class is associated with a points earning multiplier, and points for flights are calculated by multiplying the fare for the flight by the fare class multiplier. Likewise, the amount of points required to be redeemed for a flight is based on the fare and fare class purchased. Under the program (i) Members are able to redeem their points for every available seat, every day, on every flight, with no blackout dates; and (ii) points do not expire so long as the Member has points-earning activity during the most recent 24 months.
Under the program, Members continue to accumulate points until the time they decide to redeem them. As a result, the program provides Members significant flexibility and options for earning and redeeming rewards. For example, Members can earn more points (and/or achieve tiered status such as A-List and Companion Pass faster) by purchasing higher fare tickets. Members also have significant flexibility in redeeming points, such as the opportunity to book in advance to take advantage of a lower fare (including many fare sales) ticket by redeeming fewer points or by being able to redeem more points and book at the last minute if seats are still available for sale. Members can also earn points through qualifying purchases with Rapid Rewards Partners (which include, for example, car rental agencies, hotels, restaurants, and retailers), as well as by using Southwest’s co-branded Chase® Visa credit card. In addition, holders of Southwest’s co-branded Chase Visa credit card are able to redeem their points for items other than travel on Southwest, such as international flights on other airlines, cruises, hotel stays, rental cars, gift cards, event tickets, and more. In addition to earning points for revenue flights and qualifying purchases with Rapid Rewards Partners, Members also have the ability to purchase, gift, and transfer points, as well as the ability to donate points to selected charities.
Southwest’s Rapid Rewards frequent flyer program features tier and Companion Pass programs for the most active Members, including “A-List” and “A-List Preferred” status. Both A-List and A-List Preferred Members enjoy benefits such as “Fly By®” priority check-in and security lane access, where available, as well as dedicated phone lines, standby priority, and an earnings bonus on eligible revenue flights (25 percent for A-List and 100 percent for A-List Preferred). In addition, A-List Preferred Members enjoy free inflight WiFi on equipped flights. Members who attain A-List or A-List Preferred status receive priority boarding privileges for an entire year. When these Customers purchase travel at least 36 hours prior to flight time, they receive the best boarding pass number available (generally, an “A” boarding pass). Members who fly 100 qualifying one-way flights or earn 110,000 qualifying points in a calendar year automatically receive a Companion Pass, which provides for unlimited free travel for one year to any destination available on Southwest for a designated companion of the qualifying Member. The Member and designated companion must travel together on the same flight.
Southwest’s Rapid Rewards frequent flyer program has been designed to drive more revenue by (i) bringing in new Customers, including new Members, as well as new holders of Southwest’s co-branded Chase Visa credit card; (ii) increasing business from existing Customers; and (iii) strengthening the Company’s Rapid Rewards hotel, rental car, credit card, and retail partnerships. The program continues to exceed the Company’s expectations with respect to the number of Members added, the amount spent per Member on airfare, the number of flights taken by Members, the number of Southwest’s co-branded Chase Visa credit card holders added, the number of points sold to business partners, and the number of frequent flyer points purchased by Members. During 2015, the Company entered into an amended co-branded credit card agreement with Chase Bank USA, N.A. Additional information regarding this amended co-branded credit card agreement, including the effect of the resulting change in accounting methodology, is provided below under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and in Note 1 to the Consolidated Financial Statements.

For the Company’s 2016 consolidated results, Customers of Southwest redeemed approximately 8.3 million flight awards, accounting for approximately 12.7 percent of revenue passenger miles flown. For the Company’s 2015 consolidated results, Customers of Southwest redeemed approximately 7.3 million flight awards, accounting for approximately 12.0 percent of revenue passenger miles flown. During 2014, the Company also operated AirTran. AirTran’s final passenger service occurred on December 28, 2014, and it has been integrated into Southwest. For the Company’s 2014 consolidated results, Customers of Southwest and AirTran redeemed approximately 6.2 million flight awards, accounting for approximately 11.0 percent of revenue passenger miles flown. The Company’s accounting policies with respect to its frequent flyer programs are discussed in more detail in Note 1 to the Consolidated Financial Statements.
Southwest.com
The Company’s Internet website, Southwest.com®, is the only avenue for Southwest Customers to purchase and manage travel online. Customers’ trips can be planned and managed directly from the Southwest.com home page. Southwest.com is designed to help make the Customer's experience personal and intuitive with features such as recognizing the Customer's location to provide relevant deals, remembering recent searches to make it easy to get to trips of interest, and a calendar view to find the best date to travel for the lowest fare. The “My Account” section of the website provides a detailed view into a Customer’s travel and loyalty activity. Southwest.com highlights points of differentiation between Southwest and other air carriers and provides information on the Company’s fare and ancillary products. In addition, Southwest.com and Swabiz.com (the Company’s business travel reservation web page) are available in a translated Spanish version, which provides Customers who prefer to transact in Spanish the same level of Customer Service provided by the English versions of the websites. Both sites meet Web Content Accessibility Guidelines (2.0, Level AA) in order to provide an optimal experience for more people with disabilities. Additionally, Southwest offers Customers a mobile website and apps (iOS and Android) to provide Customers the ability to transact with Southwest anytime they have access to their mobile device. For the year ended December 31, 2016, approximately 79.1 percent of the Company’s Passenger revenues came through its website (including revenues from SWABIZ®).
Marketing
During 2016, the Company continued to aggressively market and benefit from Southwest’s points of differentiation from its competitors. For example, the Company’s TransfarencySM campaign emphasizes Southwest's approach to treating Customers fairly, honestly, and respectfully, with its low fares and no unexpected bag fees, change fees, or hidden fees.
Southwest continues to be the only major U.S. airline that offers to all ticketed Customers up to two checked bags that fly free (weight and size limits apply). Through both its national and local marketing campaigns, Southwest has continued to aggressively promote this point of differentiation from its competitors with its “Bags Fly Free®” message. The Company believes its decision not to charge for first and second checked bags, as reinforced by the Company’s related marketing, has driven an increase in the Company’s market share and a resulting net increase in revenues.
Southwest is also the only major U.S. airline that does not charge a fee on any of its fares for a Customer change in flight reservations. The Company has continued to incorporate this key point of differentiation in its marketing campaigns. The campaigns highlight the importance to Southwest of Customer Service by showing that Southwest understands plans can change and therefore does not charge a change fee. While a Customer may pay a difference in airfare, the Customer will not be charged a change fee on top of any difference in airfare.
Also unlike most of its competitors, Southwest does not impose additional fees for items such as seat selection, snacks, curb-side check-in, and telephone reservations. In addition, Southwest allows each ticketed Customer to check one stroller and one car seat free of charge, in addition to the two free checked bags.
The Company also continues to promote all of the many other reasons to fly Southwest such as its low fares, network size, Customer Service, free live television offerings, and its Rapid Rewards frequent flyer program.
In 2014, the Company launched a new visual expression of its brand - Heart - to symbolize the Company’s care, trust, and belief in providing exceptional Hospitality, and its Employees’ dedication to connecting Customers with what is important in their lives. The Company introduced a new Heart aircraft livery, airport experience, and logo. Aircraft already in the Company's fleet were scheduled to receive the newly painted livery within the aircraft's existing repainting schedule, while new aircraft have been delivered in the Heart livery. In 2016, the Company unveiled the next phase

9


of the Heart brand with the introduction of its first aircraft with a new Heart cabin interior. The new 737-800 interiors, which will also be included in the Company’s 737-8 aircraft, give Southwest Customers a look and feel of the future, with bold blue seats and additional seat width and legroom, an adjustable headrest, enhanced back comfort, and extra room for personal belongings. In addition, in mid-2017, front-line Employees will begin wearing Employee-designed uniforms that highlight the Company’s red and blue Heart brand.

Technology Initiatives

The Company has committed significant resources to technology improvements to support its ongoing operations and initiatives. Of particular significance is the Company’s multi-year project to completely replace its reservation system. In 2014, the Company launched the Amadeus Altéa reservations solution to support the Company’s international service. The Company has since begun implementing Amadeus' Altéa reservations solution as the Company's future single reservation system for both domestic and international reservations. The implementation consists of two foundational releases. Release 1 was completed in December 2016, and added functionality to enable the sale of domestic tickets on the new reservation system. Release 2 is expected to be completed on May 9, 2017, and will add functionality to enable operational capabilities such as passenger check-in and boarding and baggage check-in on the new reservation system. Subsequent releases will add functionality to enable revenue enhancements, further schedule optimization, support for international growth, and additional foundational and operational capabilities.

The Company has also added a new schedule optimization tool to assist with creating flight schedules that better reflect Customer demand. With this new schedule optimization tool, the Company is able to better optimize and evaluate a higher volume of potential schedules.

The Company intends to continue to devote significant technology resources towards, among other things, (i) the continued development of systems to improve both revenue management and network optimization capabilities, (ii) the aforementioned replacement of Southwest's existing domestic reservation system with the comprehensive Amadeus Altéa reservations solution, and (iii) tools to improve operational management.

Regulation

The airline industry is heavily regulated, especially by the federal government, and there are a significant number of governmental agencies and legislative bodies that have the ability to directly or indirectly affect the Company and/or the airline industry financially and/or operationally. Examples of regulations affecting the Company and/or the airline industry, imposed by several of these governmental agencies and legislative bodies, are discussed below.

Economic and Operational Regulation

Consumer Protection Regulation by the U.S. Department of Transportation

The DOT regulates economic operating authority for air carriers and consumer protection for airline passengers. The FAA, a sub-agency of the DOT, regulates aviation safety. The DOT may impose civil penalties on air carriers for violating its regulations.

To provide passenger transportation in the United States, a domestic airline is required to hold both a Certificate of Public Convenience & Necessity from the DOT and an Air Carrier Operating Certificate from the FAA. A Certificate of Public Convenience & Necessity is unlimited in duration, and the Company’s certificate generally permits it to operate among any points within the United States and its territories and possessions. Additional DOT authority, in the form of a certificate or exemption from certificate requirements, is required for a U.S. airline to serve foreign destinations either with its own aircraft or via code-sharing with another airline. Exemptions granted by the DOT to serve international markets are generally limited in duration and are subject to periodic renewal requirements. The DOT also has jurisdiction over international tariffs and pricing in certain markets. The DOT may revoke a certificate or exemption, in whole or in part, for intentional failure to comply with federal aviation statutes, regulations, orders, or the terms of the certificate itself.

10


The DOT’s consumer protection and enforcement activities relate to areas such as unfair and deceptive practices and unfair competition by air carriers, deceptive airline advertising (concerning, e.g., fares, ontime performance, schedules, and code-sharing), and violations of rules concerning denied boarding compensation, ticket refunds, and baggage liability requirements. The DOT is also charged with prohibiting discrimination by airlines against consumers on the basis of race, religion, national origin, or sex.
Under the above-described authority, the DOT has adopted so-called “Passenger Protection Rules,” which address a wide variety of matters, including flight delays on the tarmac, chronically delayed flights, denied boarding compensation, and advertising of airfares, among others. Under the Passenger Protection Rules, U.S. passenger airlines are required to adopt contingency plans that include the following: (i) assurances that no domestic flight will remain on the airport tarmac for more than three hours before beginning to return to the gate and that no international flight will remain on the tarmac at a U.S. airport for more than four hours before beginning to return to the gate, unless the pilot-in-command determines there is a safety-related or security-related impediment to deplaning passengers, or air traffic control advises the pilot-in-command that returning to the gate or permitting passengers to disembark elsewhere would significantly disrupt airport operations; (ii) an assurance that air carriers will provide adequate food and potable drinking water no later than two hours after the aircraft leaves the gate (in the case of departure) or touches down (in the case of arrival) if the aircraft remains on the tarmac, unless the pilot-in-command determines that safety or security considerations preclude such service; and (iii) an assurance of operable lavatories, as well as adequate medical attention, if needed. Air carriers are required to publish their contingency plans on their websites.
The Passenger Protection Rules also subject airlines to potential DOT enforcement action for unfair and deceptive practices in the event of chronically delayed domestic flights (i.e., domestic flights that operate at least ten times a month and arrive more than 30 minutes late more than 50 percent of the time during that month). In addition, airlines are required to (i) display ontime performance on their websites; (ii) adopt customer service plans, publish those plans on their website, and audit their own compliance with their plans; (iii) designate an employee to monitor the performance of their flights; (iv) provide information to passengers on how to file complaints; and (v) respond in a timely and substantive fashion to consumer complaints.
The Passenger Protection Rules also require airlines to (i) pay up to $1,350 in compensation to each passenger denied boarding involuntarily from an oversold flight; (ii) refund any checked bag fee for permanently lost luggage; (iii) prominently disclose all potential fees for optional ancillary services on their websites; and (iv) refund passenger fees paid for ancillary services if a flight cancels or oversells and a passenger is unable to take advantage of such services.
The Passenger Protection Rules also require that (i) advertised airfares include all government-mandated taxes and fees; (ii) passengers be allowed to hold a reservation for up to 24 hours without making a payment; (iii) passengers be allowed to cancel a paid reservation without penalty for 24 hours after the reservation is made, as long as the reservation is made at least seven days in advance of travel; (iv) fares may not increase after purchase; (v) baggage fees must be disclosed to the passenger at the time of booking; (vi) the same baggage allowances and fees must apply throughout a passenger’s trip; (vii) baggage fees must be disclosed on e-ticket confirmations; and (viii) passengers must be promptly notified in the event of delays of more than 30 minutes or if there is a cancellation or diversion of their flight.
In November 2016, the DOT finalized an additional “Passenger Protection Rule.” The new rule is intended to make the DOT’s rankings of airline performance (such as mishandled bags and ontime performance) more accurate. To do so, the DOT removed the assumption that every passenger checks a bag, and will now calculate mishandled bags per overall checked bags, rather than per enplaned passengers. The new rule also expands the pool of air carriers that must report performance data to the DOT’s Bureau of Transportation Statistics by requiring reporting air carriers to include data for their domestic scheduled flights operated by their code-share partners.

The DOT has expressed its intent to aggressively investigate alleged violations of its consumer protection rules. Airlines that violate any DOT regulation are subject to potential fines of up to $32,140 per occurrence.

The Company is also monitoring other potential rulemakings that could impact its business such as a DOT proposed rule to require air carriers to publicly disclose the revenues received from the sale of ancillary services to passengers. In addition, in December 2016, the DOT issued a proposed rule to require sellers of air transportation to provide adequate advance notice to passengers if the carrier operating the flight allows passengers to make voice calls using

11


mobile wireless devices onboard aircraft. The DOT is also considering whether such advance notice is sufficient, or whether to prohibit airlines from allowing voice calls via passenger mobile wireless devices on domestic and/or international flights. Further, in December 2016, the DOT announced the outlines of a proposed rule that the DOT intends to publish in July 2017 for the purpose of improving accessibility of lavatories on single-aisle aircraft and of in-flight entertainment. The DOT’s announcement contemplates that the proposed rule will require both short-term and long-term measures be taken to fully address the challenges persons with mobility impairments face when traveling on single-aisle aircraft, including the eventual requirement that accessible lavatories be available for individuals who use wheelchairs. The future proposed rule is also expected to address the improvement of accessibility of in-flight entertainment by requiring certain movies and shows displayed on such aircraft to be captioned to provide access to deaf and hard of hearing passengers. In addition, audio described entertainment would be available to enable people who are blind to listen to the visual narration of movies and shows.
Aviation Taxes and Fees
The statutory authority for the federal government to collect most types of aviation taxes, which are used, in part, to finance programs administered by the FAA, must be periodically reauthorized by the U.S. Congress. In 2012, Congress adopted the FAA Modernization and Reform Act of 2012, which extended most commercial aviation taxes through September 30, 2015. In September 2015 and again in July 2016, Congress extended the expiration date, which is currently September 30, 2017. Congress is expected to try to enact a new FAA reauthorization bill in 2017, which may make substantive changes with respect to aviation taxes (including, possibly, airport-assessed passenger facility charges) and/or FAA offices and programs that are financed through aviation tax revenue. Congress must either adopt a new FAA reauthorization bill or pass a “status quo” extension by September 30, 2017; otherwise, a lapse in the statutory authority could affect the airlines’ and passengers’ respective tax burdens, as well as impact the FAA’s ability to fund airport grants and regulate the airline industry.
In addition to FAA-related taxes, there are additional federal taxes related to the U.S. Department of Homeland Security. These taxes do not need to be reauthorized periodically. Congress has set the Transportation Security Fee paid by passengers at $5.60 per one-way passenger trip. In December 2015, Congress enacted another statute that indexes immigration and customs fees to inflation, beginning in 2016. These two fees are paid by inbound international passengers and are used to support the operations of U.S. Customs and Border Protection (“CBP”). Finally, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service published a final regulation in October 2015 that modifies international agriculture inspection fees. Under this rule, which was effective December 28, 2015, the per-passenger agriculture inspection fee is $5.00 and the per-commercial aircraft fee is $225.00.
In 2017, in addition to FAA reauthorization legislation, Congress may consider comprehensive tax reform legislation, which could result in a lower corporate tax rate, the elimination of certain tax deductions and preferences, and impacts to the international tax environment. Grants to airports and/or airport bond financing may also be affected through future legislation, which could result in higher fees, rates, and charges at many of the airports the Company serves.
Operational, Safety, and Health Regulation
The FAA has the authority to regulate safety aspects of civil aviation operations. Specifically, the Company and its third-party service providers are subject to the jurisdiction of the FAA with respect to aircraft maintenance and operations, including equipment, ground facilities, dispatch, communications, flight training personnel, and other matters affecting air safety. The FAA, acting through its own powers or through the appropriate U.S. Attorney, has the power to bring proceedings for the imposition and collection of fines for violation of the FAA regulations.
To address compliance with its regulations, the FAA requires airlines to obtain the Air Carrier Operating Certificate and other certificates, approvals, and authorities. These certificates, approvals, and authorities are subject to suspension or revocation for cause.
The FAA has rules in effect with respect to flight, duty, and rest regulations. Among other things, the rules require a ten hour minimum rest period prior to a pilot’s flight duty period; mandate that a pilot must have an opportunity for eight hours of uninterrupted sleep within the rest period; and impose pilot “flight time” and “duty time” limitations based upon report times, the number of scheduled flight segments, and other operational factors. The rules affect the Company’s staffing flexibility, which could impact the Company’s operational performance, costs, and Customer Experience.

12



In addition to its role as safety regulator, the FAA also operates the nation’s air traffic control (“ATC”) system and continues its lengthy and ongoing effort to implement a multi-faceted, next generation ATC system (“NextGen”). The Air Traffic Organization (“ATO”) is the operational arm of the FAA. The ATO is responsible for providing safe and efficient air navigation services to all of the United States and large portions of the Atlantic and Pacific Oceans and the Gulf of Mexico. The Company is subject to any operational changes imposed by the FAA/ATO as they relate to the “NextGen” program, as well as the day-to-day management of the air traffic control system. The FAA reauthorization discussed above under “Aviation Taxes and Fees,” as well as the annual appropriation legislation that will fund the DOT and the FAA in federal fiscal years 2017 and 2018, could include provisions impacting future FAA safety-related activities and ATO operations in 2017 and beyond.
The Company is subject to various other federal, state, and local laws and regulations relating to occupational safety and health, including Occupational Safety and Health Administration and Food and Drug Administration regulations.
Security Regulation
Pursuant to the Aviation and Transportation Security Act (“ATSA”), the Transportation Security Administration (the “TSA”), a division of the U.S. Department of Homeland Security, is responsible for certain civil aviation security matters. ATSA and subsequent TSA regulations and procedures implementing ATSA address, among other things, (i) flight deck security; (ii) the use of federal air marshals onboard flights; (iii) airport perimeter access security; (iv) airline crew security training; (v) security screening of passengers, baggage, cargo, mail, employees, and vendors; (vi) training and qualifications of security screening personnel; (vii) provision of passenger data to CBP; and (viii) background checks. Under ATSA, substantially all security officers at airports are federal employees, and significant other elements of airline and airport security are overseen and performed by federal employees, including federal security managers, federal law enforcement officers, and federal air marshals. TSA personnel and TSA-mandated security procedures can affect the Company’s operations, costs, and Customer experience. For example, as part of its security measures, the TSA regulates the types of liquid items that can be carried onboard aircraft. In addition, as part of its Secure Flight program, the TSA requires airlines to collect a passenger’s full name (as it appears on a government-issued ID), date of birth, gender, and Redress Number (if applicable). Airlines must transmit this information to Secure Flight, which uses the information to perform matching against terrorist watch lists. After matching passenger information against the watch lists, Secure Flight transmits the matching results back to airlines. This serves to identify individuals for enhanced security screening and to prevent individuals on watch lists from boarding an aircraft. It also helps prevent the misidentification of passengers who have names similar to individuals on watch lists. The TSA has also implemented enhanced security procedures as part of its enhanced, multi-layer approach to airport security, including physical pat down procedures, at security checkpoints. Such enhanced security procedures have raised privacy concerns by some air travelers.
The Company, in conjunction with the TSA and CBP, participates in TSA PreCheck™, a pre-screening initiative that allows a select group of low risk passengers to move through security checkpoints with greater efficiency and ease when traveling. Eligible passengers may use dedicated screening lanes at certain airports the Company serves for screening benefits, which include leaving on shoes, light outerwear, and belts, as well as leaving laptops and permitted liquids in carryon bags.
The Company also participates in the TSA Known Crewmember® program, which is a risk-based screening system that enables TSA security officers to positively verify the identity and employment status of flight-crew members. The program expedites flight crew member access to sterile areas of airports.
The Company works collaboratively with foreign national governments and airports to provide risk-based security measures at international departure locations.
The Company has filed an application with the Department of Homeland Security for designation under the Support Anti-Terrorism by Fostering Effective Technologies Act of 2002 (the "SAFETY Act"). The application is currently under review by the Department of Homeland Security. The Company's application for designation is based on certain safety and security procedures put in place by the Company to date related to the protection of its Employees, Customers, and assets from terrorists and other criminal activities. If the application for designation is successful, the Company would be granted certain limitations of liability for claims arising out of an "act of terrorism" as defined under the SAFETY Act.

13


The Company has also made significant investments to address the effect of security regulations, including investments in facilities, equipment, and technology to process Customers, checked baggage, and cargo efficiently; however, the Company is not able to predict the impact, if any, that various security measures or the lack of TSA resources at certain airports will have on Passenger revenues and the Company’s costs, either in the short-term or the long-term.
Environmental Regulation
The Company is subject to various federal laws and regulations relating to the protection of the environment, including the Clean Air Act, the Resource Conservation and Recovery Act, the Clean Water Act, the Safe Drinking Water Act, and the Comprehensive Environmental Response, Compensation and Liability Act, as well as state and local laws and regulations. These laws and regulations govern aircraft drinking water, emissions, and storm water discharges from operations, and the disposal of materials such as jet fuel, chemicals, hazardous waste, and aircraft deicing fluid. Additionally, in conjunction with airport authorities, other airlines, and state and local environmental regulatory agencies, the Company, as a normal course of business, undertakes voluntary investigation or remediation of soil or groundwater contamination at several airport sites. The Company does not believe that any environmental liability associated with these airport sites will have a material adverse effect on the Company’s operations, costs, or profitability, nor has it experienced any such liability in the past that has had a material adverse effect on its operations, costs, or profitability. Further regulatory developments pertaining to the control of engine exhaust emissions from ground support equipment could increase operating costs in the airline industry. The Company does not believe, however, that pending environmental regulatory developments in this area will have a material effect on the Company’s capital expenditures or otherwise materially adversely affect its operations, operating costs, or competitive position.
The federal government, as well as several state and local governments, the governments of other countries, and the United Nations’ International Civil Aviation Organization (“ICAO”) are considering legislative and regulatory proposals and voluntary measures to address climate change by reducing green-house gas emissions. At the federal level, in July 2016, the Environmental Protection Agency (the “EPA”) issued a final endangerment finding for greenhouse gas emissions from certain types of aircraft engines, which the agency determined contribute to the pollution that causes climate change and endangers public health and the environment. Following this endangerment finding, per the federal Clean Air Act, the EPA is required to promulgate new regulations for controlling greenhouse gas emissions from aircraft, including possibly new carbon-efficiency standards on aircraft and engine manufacturers. The EPA’s endangerment finding preceded an expected agreement reached by the member nations of ICAO. In October 2016, the ICAO Assembly adopted a new “global market-based measure” framework in an effort to control carbon dioxide emissions from international aviation. The focal point of this framework is a future carbon offsetting system on aircraft operators designed to cap the growth of international aviation emissions. Details of this system are expected to be further developed in 2017 and, assuming the U.S. Government adopts the ICAO framework, this system is scheduled to be phased-in beginning in 2021. Regardless of the method of regulation, policy changes with regards to climate change are possible, which could significantly increase operating costs in the airline industry and, as a result, adversely affect operations.
In addition to climate change, aircraft noise continues to be an environmental focus, especially as the FAA implements new flight procedures as part of its “NextGen” airspace modernization program discussed above. The Airport Noise and Capacity Act of 1990 gives airport operators the right, under certain circumstances, to implement local noise abatement programs, so long as they do not unreasonably interfere with interstate or foreign commerce or the national air transportation system. Some airports have established airport restrictions to limit noise, including restrictions on aircraft types to be used and limits on the number of hourly or daily operations or the time of operations. These types of restrictions can cause curtailments in service or increases in operating costs and can limit the ability of air carriers to expand operations at the affected airports. At the federal level, the FAA is considering changes to enhance community engagement when developing new flight procedures, and there is a possibility that Congress may enact legislation in 2017 to address local noise concerns at one or more commercial airports in the United States.

The Company has undertaken a number of fuel conservation and carbon emission reduction initiatives such as the following:

•
installation of blended winglets, which reduce drag and increase fuel efficiency, on all Boeing 737-700 and 737-800 aircraft in Southwest’s fleet;

14


•
upgrading of the Company’s 737-800 fleet with newly designed, split scimitar winglets;
•
periodic engine washes;
•
use of electric ground power for aircraft air and power at the gate and for ground support equipment at select locations;
•
deployment of auto-throttle and vertical navigation to maintain optimum cruising speeds;
•
implementation of engine start procedures to support the Company's single engine taxi procedures;
•
adjustment of the timing of auxiliary power unit starts on originating flights to reduce auxiliary power unit usage;
•
implementation of fuel planning initiatives to safely reduce loading of excess fuel;
•
aircraft cabin interior retrofitting to reduce weight;
•
reduction of aircraft engine idle speed while on the ground, which also increases engine life;
•
galley refreshes with dry goods weight reduction;
•
Company optimized routes (flying the best wind routes to take advantage of tailwinds or to minimize headwinds);
•
improvements in flight planning algorithms to better match the Company's aircraft flight management system (and thereby enabling the Company to fly at the most efficient altitudes);
•
substitution of Pilot and Flight Attendant flight bags with lighter Electronic Flight Bag tablets; and
•
implementation of Real Time Descent Winds (automatic uplinking of up-to-date wind data to the aircraft allowing crews to time the descent to minimize thrust inputs).
The Company has also participated in Required Navigation Performance (“RNP”) operations as part of the FAA’s Performance Based Navigation program, which is intended to modernize the U.S. Air Traffic Control System by addressing limitations on air transportation capacity and making more efficient use of airspace. RNP combines the capabilities of advanced aircraft avionics, Global Positioning System ("GPS") satellite navigation (instead of less precise ground-based navigation), and new flight procedures to (i) enable aircraft to carry navigation capabilities rather than relying on airports; (ii) improve operational capabilities by opening up many new and more direct airport approach paths to produce more efficient flight patterns; and (iii) conserve fuel, improve safety, and reduce carbon emissions. By the end of 2016, Southwest had conducted approximately 39,000 RNP approaches, including over 15,000 in 2016. Southwest must rely on RNP approaches published by the FAA, and the rate of introduction of RNP approaches continues to be slower than expected, with fuel efficient RNP approaches currently available at only 52 of Southwest’s airports. In addition, even at airports with approved RNP approaches, the clearance required from air traffic controllers to perform RNP approaches is sometimes not granted. Southwest continues to work with the FAA to develop more RNP approaches and to modify air traffic control rules to support greater utilization of RNP.
As part of its commitment to corporate sustainability, the Company has published the Southwest One ReportTM describing the Company’s sustainability strategies, which include these and other efforts to reduce greenhouse gas emissions and address other environmental matters such as energy and water conservation, waste minimization, and recycling. Information contained in the Southwest One Report is not incorporated by reference into, and does not constitute a part of, this Form 10-K.
International Regulation
All international air service is subject to certain U.S. federal requirements and approvals, as well as the regulatory requirements of the appropriate authorities of the foreign countries involved. The Company has obtained the necessary economic authority from the DOT, as well as approvals required by the FAA and applicable foreign government entities, to conduct operations, under certain circumstances, to points outside of the continental United States currently served by the Company. Certain international authorities and approvals held by the Company are subject to periodic renewal requirements. The Company requests extensions of such authorities and approvals when and as appropriate. To the extent the Company seeks to serve additional foreign destinations in the future, or to renew its authority to serve certain routes, it may be required to obtain necessary authority from the DOT and/or approvals from the FAA, as well as any applicable foreign government entity.
Certain international route authorities are governed by bilateral air transportation agreements between the United States and foreign countries. Changes in U.S. or foreign government aviation policies could result in the alteration or termination of such agreements, diminish the value of the Company’s existing international authorities, present barriers to renewing existing or securing new authorities, or otherwise affect the Company’s international operations. In

15


particular, there is a significant amount of uncertainty about the future of scheduled commercial flight operations between the United States and Cuba. Moreover, there could be challenges in expanding the Company’s flight offerings to and from Mexico, as the Mexican government adjusts to a new bilateral air transport agreement between the United States and Mexico, which went into effect in August 2016 and represents a significant change from the prior, more restrictive bilateral agreement. There are also capacity limitations at one or more Mexican airports, which could impact future service levels. In general, bilateral agreements between the United States and foreign countries the Company currently serves, or may serve in the future, may be subject to renegotiation or reinterpretation from time to time. While the U.S. government has negotiated “open skies” agreements with many countries, which allow for unrestricted access between the United States and respective foreign destinations, agreements with other countries may restrict the Company’s entry and/or growth opportunities.
The CBP is the federal agency of the U.S. Department of Homeland Security charged with facilitating international trade, collecting import duties, and enforcing U.S. regulations with respect to trade, customs, and immigration. As the Company expands its international flight offerings, CBP and its requirements and resources will also become increasingly important considerations to the Company. For instance, with the exception of flights from a small number of foreign “preclearance” locations, arriving international flights may only land at CBP-designated airports, and CBP officers must be present and in sufficient quantities at those airports to effectively process and inspect arriving international passengers and cargo. Thus, CBP personnel and CBP-mandated procedures can affect the Company’s operations, costs, and Customer experience. The Company has made and expects to continue to make significant investments in facilities, equipment, and technologies at certain airports in order to improve the Customer experience and to assist CBP with its inspection and processing duties; however, the Company is not able to predict the impact, if any, that various CBP measures or the lack of CBP resources will have on Company revenues and costs, either in the short-term or the long-term.
Insurance
The Company carries insurance of types customary in the airline industry and in amounts the Company deems adequate to protect the Company and its property and to comply both with federal regulations and certain of the Company’s credit and lease agreements. The policies principally provide coverage for public and passenger liability, property damage, cargo and baggage liability, loss or damage to aircraft, engines, and spare parts, and workers’ compensation. In addition, the Company carries a cyber-security insurance policy with regards to data protection and business interruption associated with both security breaches from malicious parties and from certain system failures.
Through the 2003 Emergency Wartime Supplemental Appropriations Act (the “Wartime Act”), the federal government has in the past provided war-risk insurance coverage to commercial carriers, including for losses from terrorism, for passengers, third parties (ground damage), and the aircraft hull. However, since the government-provided supplemental coverage from the Wartime Act was set to expire during 2014, the Company proactively canceled its government provided war-risk insurance coverage prior to expiration and purchased war-risk (terrorism) insurance in the commercial insurance marketplace.
Although the Company was able to purchase war-risk (terrorism) insurance via the commercial insurance marketplace, available commercial insurance could be more expensive in the future and/or have material differences in coverage than insurance that has historically been provided and may not be adequate to protect the Company's risk of loss from future acts of terrorism. Further, available cyber-security insurance with regards to data protection and business interruption could be more expensive in the future and/or have material differences in coverage than insurance that has historically been provided and may not be adequate to protect the Company’s risk of loss
Competition
Competition within the airline industry is intense and highly unpredictable, and Southwest currently competes with other airlines on virtually all of its scheduled routes. As a result of moderately improved economic conditions and an increased focus by airlines on costs, the airline industry has become increasingly competitive in recent years with healthier financial condition and improved profitability.
Key competitive factors within the airline industry include (i) pricing and cost structure; (ii) routes, frequent flyer programs, and schedules; and (iii) customer service, comfort, and amenities. Southwest also competes for customers with other forms of transportation, as well as alternatives to travel. In recent years, the majority of domestic airline

16


service has been provided by Southwest and the other largest major U.S. airlines, including American Airlines, Delta Air Lines, and United Airlines. The DOT defines major U.S. airlines as those airlines with annual revenues of at least $1 billion; there are currently 13 passenger airlines offering scheduled service, including Southwest, that meet this standard.
Pricing and Cost Structure
Pricing is a significant competitive factor in the airline industry, and the availability of fare information on the Internet allows travelers to easily compare fares and identify competitor promotions and discounts. Many airlines also continue to introduce new fare products to capture the full spectrum of price-sensitive travelers. These fare options range from a “basic” entry-level fare product to a “premium” economy product at a higher price point. Pricing can be driven by a variety of factors. For example, airlines often discount fares to drive traffic in new markets or to stimulate traffic when necessary to improve load factors and/or cash flow. In addition, multiple airlines have been able to reduce fares because they have been able to lower their operating costs as a result of reorganization within and outside of bankruptcy. Further, some of the Company’s competitors have continued to grow and modernize their fleets and expand their networks, potentially enabling them to better control costs per available seat mile (the average cost to fly an aircraft seat (empty or full) one mile), which in turn may enable them to lower their fares.
The Company believes its low-cost operating structure continues to provide it with an advantage over many of its airline competitors by enabling it to continue to charge low fares. However, certain so-called “ultra low-cost carriers” have surpassed the Company’s cost advantage while continuing to add aircraft, expand their networks, and add competition to the Company’s routes. Nevertheless, the Company believes it continues to have a competitive advantage through its differentiation of Southwest from all of its major competitors by not charging additional fees for items such as first and second checked bags, flight changes, seat selection, snacks, curb-side check-in, and telephone reservations.
Routes, Frequent Flyer Programs, and Schedules
The Company also competes with other airlines based on markets served, frequent flyer opportunities, and flight schedules. Some major airlines have more extensive route structures than Southwest, including more extensive international networks. In addition, many competitors have entered into significant commercial relationships with other airlines, such as global alliances, code-sharing, and capacity purchase agreements, which increase the airlines’ opportunities to expand their route offerings. An alliance or code-sharing agreement enables an airline to offer flights that are operated by another airline and also allows the airline’s customers to book travel that includes segments on different airlines through a single reservation or ticket. As a result, depending on the nature of the specific alliance or code-sharing arrangement, a participating airline may be able to (i) offer its customers access to more destinations than it would be able to serve on its own, (ii) gain exposure in markets it does not otherwise serve, or (iii) increase the perceived frequency of its flights on certain routes. Alliance and code-sharing arrangements not only provide additional route flexibility for participating airlines, they can also allow these airlines to offer their customers more opportunities to earn and redeem frequent flyer miles or points. A capacity purchase agreement enables an airline to expand its route structure by paying another airline (e.g., a regional airline with smaller aircraft) to operate flights on its behalf in markets that it does not, or cannot, serve itself. The Company continues to evaluate and implement initiatives to better enable itself to offer additional itineraries.
Customer Service, Comfort, and Amenities
Southwest also competes with other airlines in areas of Customer Service such as ontime performance, passenger amenities, flight equipment type, and comfort. According to statistics published by the DOT, Southwest consistently ranks at or near the top among domestic carriers in Customer Satisfaction for having the lowest Customer complaint ratio. Some airlines have more seating options and associated passenger amenities than does Southwest, including first-class, business class, and other premium seating and related amenities. Additionally, some major U.S. airlines, including Southwest, are adding a significant number of new aircraft to their fleets. Such efforts could provide cost benefits to these airlines through fleet simplification, improved fuel efficiencies, and lower maintenance costs. Additionally, such new aircraft could have newer and different passenger amenities than those contained in the Company’s existing fleet.
Other Forms of Competition

17


The airline industry is subject to varying degrees of competition from surface transportation by automobiles, buses, and trains. Inconveniences and delays associated with air travel security measures can increase surface competition. In addition, surface competition can be significant during economic downturns when consumers cut back on discretionary spending and fewer choose to fly, or when gasoline prices are lower, making surface transportation a less expensive option. Because of the relatively high percentage of short-haul travel provided by Southwest, it is particularly exposed to competition from surface transportation in these instances. The airline industry is also subject to competition from alternatives to travel such as videoconferencing and the Internet, which can increase in the event of travel inconveniences and economic downturns. The Company is subject to the risk that air travel inconveniences and economic downturns may, in some cases, result in permanent changes to consumer behavior in favor of surface transportation and electronic communications.
Seasonality
The Company’s business is seasonal. Generally, in most markets the Company serves, demand for air travel is greater during the summer months, and therefore, revenues in the airline industry tend to be stronger in the second (April 1 - June 30) and third (July 1 - September 30) quarters of the year than in the first (January 1 - March 31) and fourth (October 1 - December 31) quarters of the year. As a result, in many cases, the Company’s results of operations reflect this seasonality. Factors that could alter this seasonality include, among others, the price of fuel, general economic conditions, extreme or severe weather, fears of terrorism or war, or changes in the competitive environment. Therefore, the Company’s quarterly operating results are not necessarily indicative of operating results for the entire year, and historical operating results in a quarterly or annual period are not necessarily indicative of future operating results.
Employees
At December 31, 2016, the Company had approximately 53,500 active fulltime equivalent Employees, consisting of approximately 22,100 flight, 2,900 maintenance, 19,500 ground, Customer, and fleet service, and 9,000 management, technology, finance, marketing, and clerical personnel (associated with non-operational departments). Approximately 83 percent of these Employees were represented by labor unions. The Railway Labor Act establishes the right of airline employees to organize and bargain collectively. Under the Railway Labor Act, collective-bargaining agreements between an airline and a labor union generally do not expire, but instead become amendable as of an agreed date. By the amendable date, if either party wishes to modify the terms of the agreement, it must notify the other party in the manner required by the Railway Labor Act and/or described in the agreement. After receipt of the notice, the parties must meet for direct negotiations. If no agreement is reached, either party may request the National Mediation Board to appoint a federal mediator. If no agreement is reached in mediation, the National Mediation Board may determine an impasse exists and offer binding arbitration to the parties. If either party rejects binding arbitration, a 30-day “cooling off” period begins. At the end of this 30-day period, the parties may engage in “self-help,” unless a Presidential Emergency Board is established to investigate and report on the dispute. The appointment of a Presidential Emergency Board maintains the “status quo” for an additional period of time. If the parties do not reach agreement during this period, the parties may then engage in “self-help.” “Self-help” includes, among other things, a strike by the union or the airline’s imposition of any or all of its proposed amendments and the hiring of new employees to replace any striking workers. The following table sets forth the Company’s Employee groups and the status of the respective collective-bargaining agreements as of December 31, 2016:

DISCLOSURE REGARDING FORWARD-LOOKING INFORMATION
This Form 10-K contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements are based on, and include statements about, the Company’s estimates, expectations, beliefs, intentions, and strategies for the future, and the assumptions underlying these forward-looking statements. Specific forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts and include, without limitation, words such as “anticipates,” “believes,” “estimates,” “expects,” “intends,” “may,” “will,” “should,” and similar expressions. Although management believes these forward-looking statements are reasonable as and when made, forward-looking statements are not guarantees of future performance and involve risks and uncertainties that are difficult to predict. Therefore, actual results may differ materially from what is expressed in or indicated by the Company’s forward-looking statements or from historical experience or the Company’s present expectations. Known material risk factors that could cause these differences are set forth below under “Risk Factors.” Additional risks or uncertainties (i) that are not currently known to the Company, (ii) that the Company currently deems to be immaterial, or (iii) that could apply to any company, could also materially adversely affect the Company’s business, financial condition, or future results.
Caution should be taken not to place undue reliance on the Company’s forward-looking statements, which represent the Company’s views only as of the date this Form 10-K is filed. The Company undertakes no obligation to update publicly or revise any forward-looking statement, whether as a result of new information, future events, or otherwise.

Item 1A.    Risk Factors
The airline industry is particularly sensitive to changes in economic conditions; in the event of unfavorable economic conditions or economic uncertainty, the Company’s results of operations could be negatively affected, which could require the Company to adjust its business strategies.
The airline industry, which is subject to relatively high fixed costs and highly variable and unpredictable demand, is particularly sensitive to changes in economic conditions. Historically, unfavorable U.S. economic conditions have driven changes in travel patterns and have resulted in reduced spending for both leisure and business travel. For some consumers, leisure travel is a discretionary expense, and short-haul travelers, in particular, have the option to replace air travel with surface travel. Businesses are able to forego air travel by using communication alternatives such as videoconferencing and the Internet or may be more likely to purchase less expensive tickets to reduce costs, which can result in a decrease in average revenue per seat. Unfavorable economic conditions, when low fares are often used to stimulate traffic, have also historically hampered the ability of airlines to raise fares to counteract any increases in fuel, labor, and other costs. Although the U.S. economy has experienced moderate economic growth over the course of the past several years, any continuing or future U.S. or global economic uncertainty could negatively affect the Company’s results of operations and could cause the Company to adjust its business strategies.
The Company’s business can be significantly impacted by high and/or volatile fuel prices, and the Company’s operations are subject to disruption in the event of any delayed supply of fuel; therefore, the Company’s strategic plans and future profitability are likely to be impacted by the Company’s ability to effectively address fuel price increases and fuel price volatility and availability.
Airlines are inherently dependent upon energy to operate, and jet fuel and oil represented approximately 22 percent of the Company’s operating expenses for 2016. Although 2016 fuel prices were lower than in 2015, as discussed above under "Business - Cost Structure," the cost of fuel can be extremely volatile and unpredictable, and even a small change in market fuel prices can significantly affect profitability. Furthermore, volatility in fuel prices can be due to many external factors that are beyond the Company’s control. For example, fuel prices can be impacted by political and economic factors, such as (i) dependency on foreign imports of crude oil and the potential for hostilities or other conflicts in oil producing areas; (ii) limited domestic refining or pipeline capacity; (iii) worldwide demand for fuel, particularly in developing countries, which can result in inflated energy prices; (iv) changes in U.S. governmental policies on fuel production, transportation, taxes, and marketing; and (v) changes in currency exchange rates.

20


The Company’s ability to effectively address fuel price increases could be limited by factors such as its historical low-fare reputation, the portion of its Customer base that purchases travel for leisure purposes, the competitive nature of the airline industry generally, and the risk that higher fares will drive a decrease in demand. The Company attempts to manage its risk associated with volatile jet fuel prices by utilizing over-the-counter fuel derivative instruments to hedge a portion of its future jet fuel purchases. However, as evidenced by the extreme decline in jet fuel prices in late 2015, energy prices can fluctuate significantly in a relatively short amount of time. Because the Company uses a variety of different derivative instruments at different price points, the Company is subject to the risk that the fuel derivatives it uses will not provide adequate protection against significant increases in fuel prices and could in fact result in hedging losses, and the Company effectively paying higher than market prices for fuel, thus creating additional volatility in the Company’s earnings. The Company is also subject to the risk that additional cash collateral may be required to be posted to fuel hedge counterparties, which could have a significant impact on the Company’s financial position and liquidity.
In addition, the Company is subject to the risk that its fuel derivatives will not be effective or that they will no longer qualify for hedge accounting under applicable accounting standards, which can create additional earnings volatility. Adjustments in the Company’s overall fuel hedging strategy, as well as the ability of the commodities used in fuel hedging to qualify for special hedge accounting, are likely to continue to affect the Company’s results of operations. In addition, there can be no assurance that the Company will be able to cost-effectively hedge against increases in fuel prices.
The Company’s fuel hedging arrangements and the various potential impacts of hedge accounting on the Company’s financial position, cash flows, and results of operations are discussed in more detail under “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Quantitative and Qualitative Disclosures About Market Risk,” and in Note 1 and Note 10 to the Consolidated Financial Statements.
The Company is also reliant upon the readily available supply and timely delivery of jet fuel to the airports that it serves. A disruption in that supply could present significant challenges to the Company’s operations and could ultimately cause the cancellation of flights and/or the inability of the Company to provide service to a particular airport.
The Company’s low-cost structure has historically been one of its primary competitive advantages, and many factors have affected and could continue to affect the Company’s ability to control its costs.
The Company’s low-cost structure has historically been one of its primary competitive advantages, as it has enabled it to offer low fares, drive traffic volume, and grow market share; however fuel and labor costs, as well as other costs such as regulatory compliance costs, can negatively affect the Company’s ability to control its costs. Furthermore, the Company has limited control over many of these costs.
Jet fuel and oil constituted approximately 22 percent of the Company’s operating expenses during 2016, and the Company’s ability to control the cost of fuel is subject to the external factors discussed in the second Risk Factor above.
Salaries, wages, and benefits constituted approximately 41 percent of the Company’s operating expenses during 2016. The Company’s ability to control labor costs is limited by the terms of its collective-bargaining agreements, and increased labor costs have negatively impacted the Company’s low-cost competitive position. As discussed further under “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” the Company’s unionized workforce, which makes up approximately 83% of its Employees, has had pay scale increases as a result of contractual rate increases. Additionally, the majority of Southwest’s unionized Employees, including its Pilots; Flight Attendants; Ramp, Operations, Provisioning, and Freight Agents; Aircraft Appearance Technicians; and Flight Crew Training Instructors, have ratified new collective-bargaining agreements during 2016, which have put pressure on the Company’s low-cost structure. Furthermore, as indicated above under “Business - Employees,” other Southwest unionized Employees, including its Mechanics; Material Specialists; and Facilities Maintenance Technicians, are in unions currently in negotiations for labor agreements, which could result in additional pressure on the Company’s low-cost structure.
As discussed above under “Business - Regulation,” the airline industry is heavily regulated, and the Company’s regulatory compliance costs are subject to potentially significant increases from time to time based on actions by regulatory agencies that are out of the Company’s control. Additionally, the Company cannot control decisions by other airlines to reduce their capacity. When this occurs, airport costs are allocated among a fewer number of total

21


flights, which can result in increased landing fees and other costs for the Company. The Company is also reliant upon third party vendors and service providers, and its low-cost advantage is also dependent in part on its ability to obtain and maintain commercially reasonable terms with those parties.
As discussed above under “Business - Insurance,” the Company carries insurance of types customary in the airline industry. Although the Company has been able to purchase war-risk (terrorism) insurance via the commercial insurance marketplace, available commercial insurance could be more expensive in the future and/or have material differences in coverage than insurance that has historically been provided and may not be adequate to protect against the Company's risk of loss from future acts of terrorism. In addition, an accident or other incident involving Southwest aircraft could result in costs in excess of its related insurance coverage, which costs could be substantial. Any aircraft accident or other incident, even if fully insured, could also have a material adverse effect on the public’s perception of the Company.
The Company cannot guarantee it will be able to maintain or improve upon its current level of low-cost advantage over many of its airline competitors. Some so called “ultra low-cost carriers” have surpassed the Company’s cost advantage while continuing to add aircraft, expand their networks, and add competition to the Company’s routes. When competitors grow their fleets and expand their networks, they are potentially able to better control costs per available seat mile. In addition, like Southwest, some competitors have plans to add a significant number of new aircraft to their fleets, which could potentially decrease their operating costs through better fuel efficiencies and lower maintenance costs. Furthermore, some of the Company’s competitors have taken advantage of reorganization in bankruptcy, and even the threat of bankruptcy, not only to lower employee pay scales, but also to decrease operating costs through renegotiated supply and financing agreements. In addition, some airlines have consolidated and reported significant cost synergies.
The Company is increasingly dependent on technology to operate its business and continues to implement substantial changes to its information systems; any failure, disruption, or breach in the Company’s information systems could materially adversely affect its operations.
The Company is increasingly dependent on the use of complex technology and systems to run its ongoing operations, and the Company continues to implement technology initiatives to support its ongoing operations and strategies.
Integration of complex systems and technology presents significant challenges in terms of costs, human resources, and development of effective internal controls. Integration also presents the risk of operational or security inadequacy or interruption, which could materially affect the Company’s ability to effectively operate its business and/or could negatively impact the Company’s results of operations. The Company is also reliant upon third party performance for timely and effective completion of many of its technology initiatives.
In the ordinary course of business, the Company’s systems will continue to require modification and refinements to address growth and changing business requirements, including requirements related to international operations. In addition, the Company’s systems may require modification to enable the Company to comply with changing regulatory requirements. Modifications and refinements to the Company’s systems have been and are expected to continue to be expensive to implement and may divert management’s attention from other matters. In addition, the Company’s operations could be adversely affected, or it could face imposition of regulatory penalties, if it were unable to timely or effectively modify its systems as necessary.
The Company has occasionally experienced system interruptions and delays that make its websites and services unavailable or slow to respond, which can prevent the Company from efficiently processing Customer transactions or providing services, and these could continue to occur in the future. These system interruptions and delays can reduce the Company’s operating revenues and the attractiveness of its services as well as increase the Company’s costs. The Company’s computer and communications systems and operations could be damaged or interrupted by catastrophic events such as fires, floods, earthquakes, tornadoes and hurricanes, power loss, computer and telecommunications failures, acts of war or terrorism, computer viruses, security breaches, and similar events or disruptions. Any of these events could cause system interruptions, delays, and loss of critical data, and could prevent the Company from processing Customer transactions or providing services, which could make the Company’s business and services less attractive and subject the Company to liability. Any of these events could damage the Company’s reputation and be expensive to remedy.


22


The Company’s business is labor intensive; therefore, the Company would be adversely affected if it were unable to maintain satisfactory relations with its Employees or its Employees’ Representatives.

The airline business is labor intensive. Salaries, wages, and benefits represented approximately 41 percent of the Company’s operating expenses for the year ended December 31, 2016. In addition, as of December 31, 2016, approximately 83 percent of the Company’s Employees were represented for collective bargaining purposes by labor unions, making the Company particularly exposed in the event of labor-related job actions. Employment-related issues that have, and continue to, impact the Company’s results of operations, some of which are negotiated items, include hiring/retention rates, pay rates, outsourcing costs, work rules, health care costs, and retirement benefits.

The Company is currently dependent on single aircraft and engine suppliers, as well as single suppliers of certain other parts; therefore, the Company would be materially adversely affected if it were unable to obtain additional equipment or support from any of these suppliers or in the event of a mechanical or regulatory issue associated with their equipment.

The Company is dependent on Boeing as its sole supplier for aircraft and many of its aircraft parts and is dependent on other suppliers for certain other aircraft parts. Although the Company is able to purchase some aircraft from parties other than Boeing, most of its purchases are directly from Boeing. Therefore, if the Company were unable to acquire additional aircraft from Boeing, or if Boeing were unable or unwilling to make timely deliveries of aircraft or to provide adequate support for its products, the Company’s operations would be materially adversely affected. In addition, the Company would be materially adversely affected in the event of a mechanical or regulatory issue associated with the Boeing 737 aircraft type, whether as a result of downtime for part or all of the Company’s fleet, increased maintenance costs, or because of a negative perception by the flying public. The Company believes, however, that its years of experience with the Boeing 737 aircraft type, as well as the efficiencies Southwest has historically achieved by operating with a single aircraft type, outweigh the risks associated with its single aircraft supplier strategy. The Company is also dependent on sole suppliers for aircraft engines and certain other aircraft parts and would therefore also be materially adversely affected in the event of the unavailability of, or a mechanical or regulatory issue associated with, engines and other parts.

Any failure of the Company to maintain the security of certain Customer-related information could result in damage to the Company’s reputation and could be costly to remediate.

The Company must receive information related to its Customers in order to run its business, and the Company’s operations depend upon secure retention and the secure transmission of information over public networks, including information permitting cashless payments. This information is subject to the risk of intrusion, tampering, and theft. Although the Company maintains systems to defend against this from occurring, these systems require ongoing monitoring and updating as technologies change, and security could be compromised, confidential information could be misappropriated, or system disruptions could occur. In the ordinary course of its business, the Company provides certain confidential, proprietary, and personal information to third parties. While the Company seeks to obtain assurances that these third parties will protect this information, there is a risk the confidentiality of data held by third parties could be breached. A compromise of the Company’s security systems could adversely affect the Company’s reputation and disrupt its operations and could also result in litigation against the Company or the imposition of penalties. In addition, it could be costly to remediate. Although the Company has not experienced cyber incidents that are individually, or in the aggregate, material, the Company has experienced cyber-attacks in the past, which have thus far been mitigated by preventative, detective, and responsive measures put in place by the Company.

The Company’s results of operations could be adversely impacted if it is unable to grow or to effectively execute its strategic plans.

Southwest has historically been regarded as a growth airline. However, organic growth remains challenging because (i) the opportunities for domestic expansion are limited; (ii) the Company's international network is relatively small and international expansion presents unique challenges; and (iii) the Company has faced an increased presence of other low-cost, low-fare carriers. As a result, the Company is reliant on the success of its revenue strategies to help offset

23


certain increasing costs and to continue to improve Customer Service. The timely and effective execution of the Company's strategic plans could be negatively affected by (i) the Company’s ability to timely and effectively implement, transition, and maintain related information technology systems and infrastructure; (ii) the Company’s ability to effectively balance its investment of incremental operating expenses and capital expenditures related to its strategies against the need to effectively control costs; and (iii) the Company’s dependence on third parties with respect to its strategic plans.

The airline industry has faced on-going security concerns and related cost burdens; further threatened or actual terrorist attacks, or other hostilities, could significantly harm the airline industry and the Company’s operations.

Terrorist attacks or other hostilities, actual and threatened, have from time to time materially adversely affected the demand for air travel and also have resulted in increased safety and security costs for the Company and the airline industry generally. Safety measures create delays and inconveniences and can, in particular, reduce the Company’s competitiveness against surface transportation for short-haul routes. Additional terrorist attacks or other hostilities, even if not made directly on the airline industry, or the fear of such attacks or other hostilities (including elevated national threat warnings or selective cancellation or redirection of flights due to terror threats) would likely have a further significant negative impact on the Company and the airline industry.

Airport capacity constraints and air traffic control inefficiencies have limited and could continue to limit the Company’s growth; changes in or additional governmental regulation could increase the Company’s operating costs or otherwise limit the Company’s ability to conduct business.

Almost all commercial service airports are owned and/or operated by units of local or state governments. Airlines are largely dependent on these governmental entities to provide adequate airport facilities and capacity at an affordable cost. Similarly, the federal government singularly controls all U.S. airspace, and airlines are completely dependent on the FAA operating that airspace in a safe and efficient manner. The current air traffic control system is mainly radar-based and supported in large part by antiquated equipment and technologies. The FAA’s protracted transition to a satellite-based air traffic control system, as well as the implementation of policies and standards that account for the precision of global positioning system-supported aircraft technologies, could continue to adversely impact airspace capacity and the overall efficiency of the system, resulting in limited opportunities for the Company to grow, longer scheduled flight times, more delays and cancellations, and increased fuel consumption and aircraft emissions. As discussed above under “Business - Regulation,” airlines are also subject to other extensive regulatory requirements. These requirements often impose substantial costs on airlines. The Company’s strategic plans and results of operations could be negatively affected by changes in law and future actions taken by domestic and foreign governmental agencies having jurisdiction over its operations, including, but not limited to:

•
increases in airport rates and charges;
•
limitations on airport gate capacity or use of other airport facilities such as the 2016 reallocation of slots at John Wayne Airport in Orange County, California, which caused the Company to reduce service at that airport;
•
limitations on route authorities;
•
actions and decisions that create difficulties in obtaining access at slot-controlled airports;
•
actions and decisions that create difficulties in obtaining operating permits and approvals;
•
changes to environmental regulations;
•
new or increased taxes or fees;
•
changes to laws that affect the services that can be offered by airlines in particular markets and at particular airports;
•
restrictions on competitive practices;
•
changes in laws that increase costs for safety, security, compliance, or other Customer Service standards;
•
changes in laws that may limit the Company's ability to enter into fuel derivative contracts to hedge against increases in fuel prices;
•
changes in laws that may limit or regulate the Company’s ability to promote the Company’s business or fares; and

24


•
the adoption of more restrictive locally-imposed noise regulations.

Because expenses of a flight do not vary significantly with the number of passengers carried, a relatively small change in the number of passengers can have a disproportionate effect on an airline’s operating and financial results. Therefore, any general reduction in airline passenger traffic as a result of any of the factors listed above could adversely affect the Company’s results of operations. In addition, in instances where the airline industry shrinks, many airport operating costs are essentially unchanged and must be shared by the remaining operating carriers, which can therefore increase the Company’s costs.

The airline industry is affected by many conditions that are beyond its control, which can impact the Company’s business strategies and results of operations.

In addition to the unpredictable economic conditions and fuel costs discussed above, the Company, like the airline industry in general, is affected by conditions that are largely unforeseeable and outside of its control, including, among others:

•
adverse weather and natural disasters;
•
outbreaks of disease;
•
changes in consumer preferences, perceptions, spending patterns, or demographic trends (including, without limitation, changes in government travel patterns due to government shutdowns or sequestration);
•
actual or potential disruptions in the air traffic control system (including, without limitation, as a result of potential FAA budget cuts due to government shutdowns or sequestration);
•
changes in the competitive environment due to industry consolidation, industry bankruptcies, and other factors;
•
air traffic congestion and other air traffic control issues; and
•
actual or threatened war, terrorist attacks, and political instability.
The airline industry is intensely competitive.
As discussed in more detail above under “Business - Competition,” the airline industry is intensely competitive. The Company’s primary competitors include other major domestic airlines, as well as regional and new entrant airlines, surface transportation, and alternatives to transportation such as videoconferencing and the Internet. The Company’s revenues are sensitive to the actions of other carriers with respect to pricing, routes, frequent flyer programs, scheduling, capacity, Customer Service, comfort and amenities, cost structure, aircraft fleet, and code-sharing and similar activities.
The Company’s future results will suffer if it does not effectively manage its expanded international operations.
As the Company expands its international flight offerings, the U.S. Customs and Border Protection (“CBP”) will become an increasingly important federal agency. CBP personnel and CBP-mandated procedures can affect the Company’s operations, costs, and Customer experience. The Company has made, and is continuing to make, significant investments in facilities, equipment, and technologies at certain airports in order to improve the Customer experience and to assist CBP with its inspection and processing duties; however, the Company is not able to predict the impact, if any, that various CBP measures or the lack of CBP resources will have on Company revenues and costs, either in the short-term or the long-term.
International flying requires the Company to modify certain processes, as the airport environment is dramatically different in certain international locations with respect to, among other things, common-use ticket counters and gate areas, local operating requirements, and cultural preferences. In addition, international flying exposes the Company to certain foreign currency risks to the extent the Company chooses to, or is required to, transact in currencies other than the U.S. dollar. To the extent the Company seeks to serve additional foreign destinations in the future, or to renew its authority to serve certain routes, it may be required to obtain necessary authority from the DOT and/or approvals from the FAA, as well as any applicable foreign government entity.
The Company’s expansion of its operations into non-U.S. jurisdictions also expands the scope of the laws to which the Company is subject, both domestically and internationally. In addition, operations in non-U.S. jurisdictions are in many cases subject to the laws of those jurisdictions rather than U.S. laws. Laws in some jurisdictions differ in significant

25


respects from those in the United States, and these differences can affect the Company’s ability to react to changes in its business, and its rights or ability to enforce rights may be different than would be expected under U.S. laws. Furthermore, enforcement of laws in some jurisdictions can be inconsistent and unpredictable, which can affect both the Company’s ability to enforce its rights and to undertake activities that it believes are beneficial to its business. As a result, the Company’s ability to generate revenue and its expenses in non-U.S. jurisdictions may differ from what would be expected if U.S. laws governed these operations. Although the Company has policies and procedures in place that are designed to promote compliance with the laws of the jurisdictions in which it operates, a violation by the Company’s Employees, contractors, or agents or other intermediaries, could nonetheless occur. Any violation (or alleged or perceived violation), even if prohibited by the Company’s policies, could have an adverse effect on the Company’s reputation and/or its results of operations.
The Company is currently subject to pending litigation, and if judgment were to be rendered against the Company in the litigation, such judgment could adversely affect the Company’s operating results.
As discussed below under “Legal Proceedings,” the Company is subject to pending litigation.
Regardless of merit, these litigation matters and any potential future claims against the Company or AirTran may be both time consuming and disruptive to the Company’s operations and cause significant expense and diversion of management attention. Should AirTran and the Company fail to prevail in these or other matters, the Company may be faced with significant monetary damages or injunctive relief that could materially adversely affect its business and might materially affect its financial condition and operating results.

Ground Facilities and Services
Southwest either leases or pays a usage fee for terminal passenger service facilities at each of the airports it serves, to which various leasehold improvements have been made. The Company leases the land and/or structures on a long-term basis for its aircraft maintenance centers (located at Dallas Love Field, Houston Hobby, Phoenix Sky Harbor, Chicago Midway, Hartsfield-Jackson Atlanta International Airport, and Orlando International Airport), its current flight training center at Dallas Love Field (which currently houses Boeing 737 flight simulators), and its main corporate headquarters building, also located at Dallas Love Field. The Company also leases a warehouse and engine repair facility in Atlanta.
The Company has commitments associated with various airport improvement projects, including ongoing construction at Fort Lauderdale-Hollywood International Airport and Los Angeles International Airport. These projects include the construction of new facilities and the rebuilding or modernization of existing facilities. Additional information regarding these projects is provided below under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and in Note 4 to the Consolidated Financial Statements.
The Company owns an additional headquarters building, located across the street from the Company’s main headquarters building, on land owned by the Company. This energy-efficient, modern building, called TOPS, houses certain operational and training functions, including its 24-hour operations. In 2016, the Company broke ground on an additional headquarters building, called Wings, designed to house flight simulators, classroom space for Pilot training, and additional work areas. The Wings building is scheduled to be completed in 2018 and is also located across the street from the Company’s main headquarters building on land owned by the Company. The Company expects to begin moving its 12 737 flight simulators to the Wings building during 2017 and expects to have all of its flight simulators in the Wings building by mid-2018. In 2017, the Company expects to add a pedestrian safety bridge to its corporate campus in order to connect the main headquarters building, the TOPS building, and the Wings building. As of December 31, 2016, the Company operated seven Customer Support and Services call centers. The centers located in Atlanta, San Antonio, Chicago, Albuquerque, and Oklahoma City occupy leased space. The Company owns its Houston and Phoenix centers.
The Company performs substantially all line maintenance on its aircraft and provides ground support services at most of the airports it serves. However, the Company has arrangements with certain aircraft maintenance firms for major component inspections and repairs for its airframes and engines, which comprise the majority of the Company’s annual aircraft maintenance costs.

Item 3.        Legal Proceedings
A complaint alleging violations of federal antitrust laws and seeking certification as a class action was filed against Delta Air Lines, Inc. and AirTran in the United States District Court for the Northern District of Georgia in Atlanta on May 22, 2009. The complaint alleged, among other things, that AirTran attempted to monopolize air travel in violation of Section 2 of the Sherman Act, and conspired with Delta in imposing $15-per-bag fees for the first item of checked luggage in violation of Section 1 of the Sherman Act. The initial complaint sought treble damages on behalf of a putative class of persons or entities in the United States who directly paid Delta and/or AirTran such fees on domestic flights beginning December 5, 2008. After the filing of the May 2009 complaint, various other nearly identical complaints also seeking certification as class actions were filed in federal district courts in Atlanta, Georgia; Orlando, Florida; and Las Vegas, Nevada. All of the cases were consolidated before a single federal district court judge in Atlanta. A Consolidated Amended Complaint was filed in the consolidated action on February 1, 2010, which broadened the allegations to add claims that Delta and AirTran conspired to reduce capacity on competitive routes and to raise prices in violation of Section 1 of the Sherman Act. In addition to treble damages for the amount of first baggage fees paid to AirTran and to Delta, the Consolidated Amended Complaint seeks injunctive relief against a broad range of alleged anticompetitive activities, as well as attorneys' fees. On August 2, 2010, the Court dismissed plaintiffs' claims that AirTran and Delta had violated Section 2 of the Sherman Act; the Court let stand the claims of a conspiracy with respect to the imposition of a first bag fee and the airlines' capacity and pricing decisions. On June 30, 2010, the plaintiffs filed a motion to certify a class, which AirTran and Delta opposed. The parties engaged in extensive discovery, and discovery has now closed. On June 18, 2012, the parties filed a Stipulation and Order that plaintiffs have abandoned their claim that AirTran and Delta conspired to reduce capacity. On August 31, 2012, AirTran and Delta moved for summary judgment on all of plaintiffs' remaining claims. The parties filed motions to exclude the opinions of the other parties' experts on class certification and on the merits. On January 8, 2016, the parties completed briefing on defendants' motions for summary judgment, plaintiffs' motion for class certification, and the motions to exclude the opinions of experts. On July 12, 2016, the Court granted plaintiffs’ motion to certify a class of all persons who paid first bag fees to AirTran or Delta from December 8, 2008 to November 1, 2014 (the date on which AirTran stopped charging first bag fees). Defendants submitted a petition to appeal the class certification decision, which the Court of Appeals for the Eleventh Circuit granted on October 7, 2016, and the appeal is ongoing. Defendants’ motions for summary judgment have been submitted for decision and are still pending. AirTran denies all allegations of wrongdoing, including those in the Consolidated Amended Complaint, and intends to defend vigorously any and all such allegations.
Also, on June 30, 2015, the U.S. Department of Justice (“DOJ”) issued a Civil Investigative Demand (“CID”) to the Company. The CID seeks information and documents about the Company’s capacity from January 2010 to the present including public statements and communications with third parties about capacity. In June 2015, the Company also received a letter from the Connecticut Attorney General requesting information about capacity; and on August 21, 2015, the Attorney General of the State of Ohio issued an investigative demand seeking information and documents about the Company’s capacity from December 2013 to the present. The Company is cooperating fully with the DOJ CID and these two state inquiries.
Further, on July 1, 2015, a complaint was filed in the United States District Court for the Southern District of New York on behalf of putative classes of consumers alleging collusion among the Company, American Airlines, Delta Air Lines, and United Airlines to limit capacity and maintain higher fares in violation of Section 1 of the Sherman Act. Since then, a number of similar class action complaints were filed in the United States District Courts for the Central District of California, the Northern District of California, the District of Columbia, the Middle District of Florida, the Southern District of Florida, the Northern District of Georgia, the Northern District of Illinois, the Southern District of Indiana, the Eastern District of Louisiana, the District of Minnesota, the District of New Jersey, the Eastern District of New York, the Southern District of New York, the Middle District of North Carolina, the District of Oklahoma, the Eastern District of Pennsylvania, the Northern District of Texas, the District of Vermont, and the Eastern District of Wisconsin. On October 13, 2015, the Judicial Panel on Multi-District Litigation centralized the cases to the United States District Court in the District of Columbia. On March 25, 2016, the plaintiffs filed a Consolidated Amended Complaint in the consolidated cases alleging that the defendants conspired to restrict capacity from 2009 to present. The plaintiffs seek to bring their claims on behalf of a class of persons who purchased tickets for domestic airline travel on the defendants' airlines from July 1, 2011 to present. They seek treble damages, injunctive relief, and attorneys' fees and expenses. On May 11, 2016, the defendants moved to dismiss the Consolidated Amended Complaint, and on October 28, 2016, the Court denied this motion. On January 31, 2017, the Court entered a case management schedule

28


that calls for discovery to be completed, and for plaintiffs to file a motion for class certification, by April 27, 2018. The Company denies all allegations of wrongdoing and intends to vigorously defend these civil cases.
In addition, on July 8, 2015, the Company was named as a defendant in a putative class action filed in the Federal Court in Canada alleging that the Company, Air Canada, American Airlines, Delta Air Lines, and United Airlines colluded to restrict capacity and maintain higher fares for Canadian residents traveling in the United States and for travel between the United States and Canada. Similar lawsuits were filed in the Supreme Court of British Columbia on July 15, 2015, Court of Queen's Bench for Saskatchewan on August 4, 2015, Superior Court of the Province of Quebec on September 21, 2015, and Ontario Superior Court of Justice on October 6, 2015. In December 2015, the Company entered into Tolling and Discontinuance agreements with putative class counsel in the Federal Court and British Columbia and Ontario proceedings and a discontinuance agreement with putative class counsel in the Quebec proceeding. The other defendants entered into an agreement with the same putative class counsel to stay the Federal Court, British Columbia, and Quebec proceedings and to proceed in Ontario. On June 10, 2016, the Federal Court granted plaintiffs' motion to discontinue that action against the Company without prejudice and stayed the action against the other defendants. On July 13, 2016, the plaintiff unilaterally discontinued the action against the Company in British Columbia. On September 28, 2016, the plaintiff filed a motion to discontinue the Quebec proceeding against the Company and to stay that proceeding against the other defendants. An initial case conference in the Ontario litigation was held on January 27, 2017, and the case managing judge scheduled a motion to discontinue that proceeding as to the Company for March 10, 2017. The time for the Company to respond to the remaining complaints has not yet expired. The plaintiffs in the remaining complaints generally seek damages (including punitive damages in certain cases), prejudgment interest, disgorgement of any benefits accrued by the defendants as a result of the allegations, injunctive relief, and attorneys' fees and other costs. The Company denies all allegations of wrongdoing and intends to vigorously defend these civil cases in Canada.
The Company is from time to time subject to various legal proceedings and claims arising in the ordinary course of business, including, but not limited to, examinations by the Internal Revenue Service.
The Company’s management does not expect that the outcome in any of its currently ongoing legal proceedings or the outcome of any proposed adjustments presented to date by the Internal Revenue Service, individually or collectively, will have a material adverse effect on the Company’s financial condition, results of operations, or cash flow.

On May 18, 2016, the Company’s Board of Directors authorized the repurchase of up to $2.0 billion of the Company’s common stock. Repurchases are made in accordance with applicable securities laws in open market, private, or accelerated repurchase transactions from time to time, depending on market conditions, and may be discontinued at any time.
(2)
Under an accelerated share repurchase program entered into by the Company with a third party financial institution in third quarter 2016 (the "Third Quarter 2016 ASR Program"), the Company paid $250 million and received an initial delivery of 4,956,384 shares during third quarter 2016, representing an estimated 75 percent of the shares to be purchased by the Company under the Third Quarter 2016 ASR Program based on a price of $37.83 per share, which was the closing price of the Company’s common stock on the New York Stock Exchange on July 22, 2016. Final settlement of this Third Quarter 2016 ASR Program occurred in October 2016 and was determined based generally on a discount to the volume-weighted average price per share of the Company's common stock during a calculation period completed in October 2016. Upon settlement, the third party financial institution delivered 1,709,877 additional shares of the Company’s common stock to the Company. In total, the average purchase price per share for the 6,666,261 shares repurchased under the Third Quarter 2016 ASR Program, upon completion of the Third Quarter 2016 ASR Program in October 2016, was $37.5023.
(3)
Under an accelerated share repurchase program entered into by the Company with a third party financial institution in fourth quarter 2016 (the "Fourth Quarter 2016 ASR Program"), the Company paid $300 million in November 2016 and received an initial delivery of 4,723,420 shares during December 2016, representing an estimated 75 percent of the shares to be purchased by the Company under the Fourth Quarter 2016 ASR Program based on a volume-weighted average price of $47.6350 per share of the Company’s common stock on the New York Stock Exchange during a calculation period between November 18, 2016 and December 8, 2016. The specific number of shares that the Company ultimately will repurchase under the Fourth Quarter 2016 ASR Program will be determined based generally on a discount to the volume-weighted average price per share of the Company’s common stock during a calculation period to be completed in February 2017. At settlement, under certain circumstances, the third party financial institution may be required to deliver additional shares of common stock to the Company, or under certain circumstances, the Company may be required to deliver shares of its common stock or may elect to make a cash payment to the third party financial institution.

Net income for the year ended December 31, 2016, was a Company record $2.24 billion, a 2.9 percent increase year-over-year, or $3.55 per diluted share. This increase was primarily driven by a 41.9 percent increase in Other operating revenues due to the Company's July 2015 amended co-branded credit card agreement ("Agreement") with Chase Bank USA, N.A. ("Chase") and a resulting required change in accounting methodology (see Note 1 to the Consolidated Financial Statements for further information), coupled with increased Passenger revenues driven by strong demand for low-fare air travel and a 5.7 percent year-over-year capacity growth. This increase was partially offset by an increase in Salaries, wages, and benefits expense, an increase in Depreciation and amortization expense, and an increase in Other operating expenses. These items are discussed in more detail below. Excluding special items in both years, non-GAAP Net income was a record $2.37 billion, a 0.6 percent increase year-over-year, or $3.75 per diluted share. Year ended December 31, 2016 Operating income was $3.8 billion and non-GAAP Operating income was $4.0 billion.

For the twelve months ended December 31, 2016, the Company produced a 30.0 percent Return on invested capital ("ROIC"), compared with 32.7 percent for the twelve months ended December 31, 2015. See the Company's calculation of ROIC in the accompanying reconciliation tables as well as the Note Regarding Use of Non-GAAP Financial Measures.

During 2016, the Company continued to return significant value to its Shareholders. The Company returned a record $2.0 billion to Shareholders through a combined $222 million in dividend payments and $1.75 billion through five separate accelerated share repurchase programs. During November 2016, the Company launched the Fourth Quarter 2016 ASR Program by advancing $300 million to a financial institution in a privately negotiated transaction. During December 2016, the Company received an initial delivery of 4.7 million shares of common stock, representing an estimated 75 percent of shares to be purchased by the Company under the Fourth Quarter 2016 ASR Program. The specific number of shares that the Company ultimately will repurchase under the Fourth Quarter 2016 ASR Program will be determined based generally on a discount to the volume-weighted average price per share of the Company's common stock during a calculation period to be completed in February 2017. The purchase was recorded as a treasury share purchase for purposes of calculating earnings per share. See Part II, Item 5 for further information on the Company's share repurchase authorizations.

Company Overview

During 2016, the Company began scheduled service to Long Beach, California and scheduled service to three Cuban cities: Havana, Varadero, and Santa Clara. With the addition of these new markets, the Company now serves 101 cities across nine countries and operates over 3,900 departures a day. Also in January 2017, the Company filed an application with the DOT to serve Owen Roberts International Airport in Grand Cayman, and announced plans to launch service to Cincinnati/Northern Kentucky International Airport, both scheduled to begin in June 2017.

The Company plans to continue its route network and schedule optimization efforts through the addition of new markets and itineraries, while also pruning less profitable flights from its schedule. The Company currently plans to grow its 2017 available seat miles approximately 3.5 percent, year-over-year, with approximately 2.5 points of that increase relating to domestic growth.

During 2016, the Company took delivery of 38 737-800 aircraft from Boeing and 23 pre-owned Boeing 737-700 aircraft from third parties. The Company also retired 31 Boeing 737-300 ("Classic") aircraft and its remaining 11 Boeing 737-500 aircraft during the year. By the end of third quarter 2017, the Company intends to retire the 87 Classic aircraft remaining in its fleet at December 31, 2016. After taking into account scheduled deliveries for new and pre-owned aircraft in 2017, this accelerated retirement schedule is expected to decrease the Company's fleet to 703 aircraft by year-end 2017. For 2018, the Company's current firm aircraft commitments would result in 743 aircraft by year-end 2018, including nine Boeing 737-800 options exercised during 2016, and two Boeing 737-800 options exercised in January 2017. See Note 4 to the Consolidated Financial Statements for further information.

The Company is the launch customer for Boeing’s new, more fuel-efficient 737-8 aircraft, which is expected to enter service in fourth quarter 2017. The 737-8 is expected to reduce fuel burn and CO2 emissions approximately 20 percent, compared with the 737-300 and 737-500 aircraft when they first entered service. Southwest is also the launch customer for the Boeing 737-7 series aircraft, with deliveries expected to begin in 2019. Currently, the Company has firm orders in place for 170 737-8 aircraft and 30 737-7 aircraft. See Note 4 to the Consolidated Financial Statements for further information.
The Company is in the midst of a multi-year project to completely replace its reservation system. In 2014, the Company launched the Amadeus Altéa reservations solution to support the Company’s international service. The Company has since begun implementing Amadeus' Altéa reservations solution as the Company's future single reservation system for both domestic and international reservations. The implementation consists of two foundational releases. Release 1 was completed in December 2016, and added functionality to enable the sale of domestic tickets on the new reservation system. Release 2 is expected to be completed on May 9, 2017 and will add functionality to enable operational capabilities such as passenger check-in and boarding and baggage check-in on the new reservation system. Subsequent releases will add functionality to enable revenue enhancements, further schedule optimization, support for international growth, and additional foundational and operational capabilities.

During 2016, the following events took place regarding the Company's unionized Employee groups in contract negotiations:
•
The Company's Flight Crew Training Instructors, represented by Transport Workers Union ("TWU") Local 557, ratified a new collective-bargaining agreement with the Company. The newly ratified contract becomes amendable in December 2019.
•
The Company's Ramp, Operations, Provisioning, and Freight Agents, represented by TWU Local 555, ratified a new collective-bargaining agreement with the Company. The newly ratified contract becomes amendable in February 2021. 
•
The Company's Pilots, represented by the Southwest Airlines Pilots' Association, ratified a new collective-bargaining agreement. The newly ratified contract becomes amendable in September 2020.

37


•
The Company's Flight Attendants, represented by TWU Local 556, ratified a new collective-bargaining agreement with the Company. The newly ratified contract becomes amendable in November 2018.
•
The Company's Aircraft Appearance Technicians, represented by the Aircraft Mechanics Fraternal Association ("AMFA"), ratified a new collective-bargaining agreement with the Company. The newly ratified contract becomes amendable in November 2020.
•
The Company's Facilities Maintenance Technicians, represented by AMFA, reached a tentative collective-bargaining agreement with the Company, which was announced in October 2016. The Facilities Maintenance Technicians failed to ratify this agreement, as announced by the Company on December 29, 2016, and the parties will continue negotiations.
2016 Compared with 2015

Operating Revenues

Passenger revenues for 2016 increased by $295 million, or 1.6 percent, compared with 2015. Holding all other factors constant, the increase was primarily attributable to a 5.7 percent increase in capacity as strong Customer demand for low-fare air travel enabled the Company to fill the additional seats, as evidenced by a Company record annual load factor of 84.0 percent. On a unit basis, Passenger revenues decreased 3.8 percent, year-over-year, largely driven by a 4.3 percent decrease in passenger revenue yield, year-over-year, which included a reduction to 2016 Passenger revenues associated with the Agreement with Chase, as a result of the required change in accounting methodology in 2015. The Agreement resulted in an acceleration of the timing of revenue recognition on a prospective basis beginning July 1, 2015, as well as a change in classification. The transportation element of the consideration received is now allocated a lower relative value, resulting in a reduction in the revenues classified as Passenger on a prospective basis, and the higher relative value associated with the non-transportation elements results in an increase in the portion of revenues classified as Other within the Consolidated Statement of Income; however, the precise revenue impact for future periods is not determinable until the volume of future transactions for the period is known. See Note 1 to the Consolidated Financial Statements for further information.

Freight revenues for 2016 decreased by $8 million, or 4.5 percent, compared with 2015, primarily due to sluggish demand. Based on current trends, the Company currently expects Freight revenues in first quarter 2017 to be comparable with first quarter 2016.

The Company recorded a Special revenue adjustment during 2015 of $172 million. This adjustment represented a one-time non-cash reduction to deferred revenue liability as a result of the Agreement with Chase and the resulting required change in accounting methodology, and is classified as a special item and thus excluded from the Company's 2015 non-GAAP financial results. See Note 1 to the Consolidated Financial Statements and the Note Regarding Use of Non-GAAP Financial Measures for further information.

Other revenues for 2016 increased $490 million, or 41.9 percent, compared with 2015, primarily as a result of the Agreement with Chase and the resulting required change in accounting methodology. This change resulted in approximately 90 percent of the increase to Other revenue year-over-year. Excluding this impact of the Agreement with Chase, Other revenues increased primarily due to higher ancillary revenues associated with EarlyBird Check-in® and A1-15 select boarding positions sold at the airport. The Company currently expects Other revenues in first quarter 2017 to increase, compared with first quarter 2016.

Based on revenue and booking trends thus far in first quarter 2017, the Company is currently expecting first quarter 2017 operating unit revenues to be flat to down one percent, compared with first quarter 2016.

Operating Expenses

Operating expenses for 2016 increased $961 million, or 6.1 percent, compared with 2015, while capacity increased 5.7 percent over the same period. Historically, except for changes in the price of fuel, changes in Operating expenses for

38


airlines have been largely driven by changes in capacity, or ASMs. The following table presents the Company's Operating expenses per ASM for 2016 and 2015, followed by explanations of these changes on a per ASM basis and dollar basis:

Operating expenses per ASM for 2016 increased by 0.4 percent, compared with 2015, primarily due to the accelerated depreciation expense associated with the planned early retirement of the Classic fleet, higher contract programming and consulting expenses associated with large technology projects, and higher wage rates due to new labor agreements. These increases were partially offset by lower jet fuel prices and lower profitsharing expense. See Note 1 to the Consolidated Financial Statements for further information on the early retirement of the Classic fleet. Operating expenses per ASM for 2016, excluding Fuel and oil expense and special items (a non-GAAP financial measure), increased 1.6 percent year-over-year. See Note Regarding Use of Non-GAAP Financial Measures and the Reconciliation of Reported Amounts to Non-GAAP Financial Measures for additional detail regarding non-GAAP financial measures. Based on current trends and excluding Fuel and oil expense, special items, and profitsharing expense, the Company expects its first quarter 2017 unit costs to increase in the six to seven percent range, compared with first quarter 2016, largely due to amended union contracts. The year-over-year projections do not reflect the potential impact of Fuel and oil expense, profitsharing expense, and special items in both years because the Company cannot reliably predict or estimate those items or expenses or their impact to its financial statements in future periods, especially considering the significant volatility of the Fuel and oil expense line item. Accordingly, the Company believes a reconciliation of non–GAAP financial measures to the equivalent GAAP financial measures for projected results is not meaningful or available without unreasonable effort. The Company currently expects to record a charge during 2017 associated with the grounding of its remaining Classic fleet. See Note 1 to the Consolidated Financial Statements for further information. This charge primarily relates to future contractual payments due to lessors for leased Classic aircraft with lease terms extending beyond third quarter 2017. The Company continues to negotiate with these lessors in order to attempt to terminate certain leases early and potentially buy-out the remainder of the lease. Therefore, the Company cannot yet accurately predict the amounts and/or timing of such charges during the first three quarters of 2017.
      
Salaries, wages, and benefits expense for 2016 increased $415 million, or 6.5 percent, compared with 2015. Salaries, wages, and benefits expense per ASM for 2016 increased 0.7 percent, compared with 2015. On both a dollar and per ASM basis, the increase was primarily due to wage rate increases as a result of agreements reached with multiple workgroups, increased training, additional headcount, and contractual increases. Based on current cost trends and anticipated capacity, the Company expects first quarter 2017 Salaries, wages, and benefits expense per ASM, excluding profitsharing expense, to increase, compared with first quarter 2016. The year-over-year projection does not reflect the potential impact of profitsharing expense in both years because the Company cannot reliably predict or estimate that expense or its impact to the Company's financial statements in future periods. Accordingly, the Company believes a reconciliation of non-GAAP financial measures to the equivalent GAAP financial measures for projected results is not meaningful or available without unreasonable effort.

During 2016, the Company conducted negotiations with various unionized Employee groups. See the above discussion in Company Overview for agreements reached during the year. The following table sets forth the Company’s unionized Employee groups that are currently in negotiations on collective-bargaining agreements:

Fuel and oil expense for 2016 increased by $31 million, or 0.9 percent, compared with 2015. On a per ASM basis, Fuel and oil expense for 2016 decreased 4.7 percent, compared with 2015, as the dollar increases were more than offset by the 5.7 percent increase in capacity. On a dollar basis, the increase was attributable to the $566 million increase in net losses resulting from the Company's fuel hedging program. Excluding the impact of hedging, Fuel and oil expense would have decreased by $535 million, or 15.9 percent, compared with 2015, due to lower market jet fuel prices. See Note Regarding Use of Non-GAAP Financial Measures and the Reconciliation of Reported Amounts to Non-GAAP Financial Measures for additional detail regarding non-GAAP financial measures. The Company's average economic jet fuel price per gallon decreased 7.2 percent year-over-year, from $2.07 for 2015 to $1.92 for 2016. Fuel gallons consumed increased 5.0 percent, compared with 2015, while year-over-year capacity increased 5.7 percent. As a result of the Company's fuel hedging program, the Company recognized net losses totaling $820 million in Fuel and oil expense for 2016, compared with net losses totaling $254 million for 2015. These totals include cash settlements realized from the settlement of fuel derivative contracts associated with the Company's "economic" fuel hedge totaling $1.0 billion paid to counterparties for 2016, compared with $577 million paid to counterparties for 2015. Additionally, these totals exclude gains and/or losses recognized from hedge ineffectiveness and from derivatives that did not qualify for hedge accounting. Those items are recorded as a component of Other (gains) losses, net. See Note 10 to the Consolidated Financial Statements.

As of January 20, 2017, on an economic basis, the Company had derivative contracts in place related to expected future fuel consumption as follows:

 
 
Maximum percent of estimated fuel consumption covered by
 
 
fuel derivative contracts at varying West Texas Intermediate/Brent Crude Oil,
Period
 
Heating Oil, and Gulf Coast Jet Fuel-equivalent price levels (1)
2017

2018
 
57%
2019
 
15%

(1) The Company’s hedge position can vary significantly at different price levels, including prices at which the Company considers “catastrophic” coverage. The percentages provided are not indicative of the Company's hedge coverage at every price, but represent the highest level of coverage at a single price. The Company believes its coverage related to first quarter 2017 is best reflected within the jet fuel forecast price sensitivity table provided below. See Note 10 to the Consolidated Financial Statements for further information.

As a result of applying hedge accounting in prior periods, including related to hedge positions that have either been offset or settled early on a cash basis, the Company has amounts “frozen” in Accumulated other comprehensive income (loss) (“AOCI”), and these amounts will be recognized in earnings in future periods when the underlying fuel derivative contracts settle. The following table displays the Company's estimated fair value of remaining fuel derivative contracts

(not considering the impact of the cash collateral provided to or received from counterparties - see Note 10 to the Consolidated Financial Statements for further information), as well as the amount of deferred gains/losses in AOCI at December 31, 2016, and the expected future periods in which these items are expected to settle and/or be recognized in earnings (in millions):

Based on forward market prices and the amounts in the above table (and excluding any other subsequent changes to the fuel hedge portfolio), the Company's jet fuel costs per gallon could exceed market (i.e., unhedged) prices during some of these future periods. This is based primarily on expected future cash settlements associated with fuel derivatives, but excludes any impact associated with the ineffectiveness of fuel hedges or fuel derivatives that are marked to market because they do not qualify for hedge accounting. See Note 10 to the Consolidated Financial Statements for further information. Assuming no changes to the Company's current fuel derivative portfolio, but including all previous hedge activity for fuel derivatives that have not yet settled, and considering only the expected net cash payments related to hedges that will settle, the Company is providing the below sensitivity table for first quarter 2017 and full year 2017 jet fuel prices at different crude oil assumptions as of January 20, 2017, and for expected premium costs associated with settling contracts each period, respectively.

(1) Brent crude oil average market prices as of January 20, 2017, were approximately $56 and $57 per barrel for first quarter 2017 and full year 2017, respectively.
(2) The economic fuel price per gallon sensitivities provided assume the relationship between Brent crude oil and refined products based on market prices as of January 20, 2017. Economic fuel cost projections do not reflect the potential impact of special items because the Company cannot reliably predict or estimate the hedge accounting impact associated with the volatility of the energy markets or the impact to its financial statements in future periods. Accordingly, the Company believes a reconciliation of non-GAAP financial measures to the equivalent GAAP financial measures for projected results is not meaningful or available without unreasonable effort.
(3) Fuel hedge premium expense is recognized as a component of Other (gains) losses, net.

Maintenance materials and repairs expense for 2016 increased by $40 million, or 4.0 percent, compared with 2015. On a per ASM basis, Maintenance materials and repairs expense for 2016 decreased 2.8 percent, compared with 2015, as the dollar increases were more than offset by the 5.7 percent increase in capacity. On a dollar basis, the majority of the increase was attributable to the timing of regular maintenance checks and ongoing cabin refresh projects including updates for the Company's new Heart cabin interior. These increases were partially offset by lower engine expense as a result of the early retirement of the Classic fleet, as this decrease in engine repairs was only partially offset by higher 737-700 engine expense due to increased flight hours. The Company currently expects Maintenance materials and repairs expense per ASM for first quarter 2017 to be comparable with fourth quarter 2016 unit cost of 0.66 cents.

41



Aircraft rentals expense for 2016 decreased by $9 million, or 3.8 percent, compared with 2015. On a per ASM basis, Aircraft rentals expense decreased 11.8 percent, compared with 2015. On both a dollar and per ASM basis, the decrease was primarily due to the retirement of five 737-300 leased aircraft and two 737-500 leased aircraft since 2015, as well as the purchase of five leased 737-300s that were previously on operating lease during 2016. See the accompanying Note Regarding Use of Non-GAAP Financial Measures for further information. The Company currently expects Aircraft rentals expense per ASM for first quarter 2017 to be comparable with fourth quarter 2016 unit cost of 0.15 cents.

Landing fees and other rentals expense for 2016 increased by $45 million, or 3.9 percent, compared with 2015. On a per ASM basis, Landing fees and other rentals expense for 2016 decreased 1.2 percent, compared with 2015, as the dollar increases were more than offset by the 5.7 percent increase in capacity. On a dollar basis, approximately 70 percent of the increase was due to higher space rental rates and usage at various airports. The remainder was due to a 3.5 percent increase in Trips flown coupled with heavier landing weights for the Company's higher capacity 737-800 aircraft, which now make up a larger portion of the Company's fleet than in 2015. The Company currently expects Landing fees and other rentals expense per ASM for first quarter 2017 to be comparable with first quarter 2016.

Depreciation and amortization expense for 2016 increased by $206 million, or 20.3 percent, compared with 2015. On a per ASM basis, Depreciation and amortization expense increased 13.9 percent, compared with 2015. On both a dollar and per ASM basis, approximately 60 percent of the increase was due to the accelerated depreciation expense resulting from a change in the estimated retirement dates of many of the Company's owned Classic fleet from mid-2021 to third quarter 2017. The remainder of the increase was due to the purchase and capital lease of new and used aircraft since 2015. The Company currently expects Depreciation and amortization expense per ASM for first quarter 2017 to increase, compared with first quarter 2016, primarily due to the purchase and capital lease of new and used aircraft since first quarter 2016 as well as depreciation associated with the implementation of technology assets, partially offset by lower depreciation, year-over-year, related to the accelerated retirement of the Classic fleet. See Note 1 to the Consolidated Financial Statements for further information.

The Company incurred no Acquisition and integration costs in 2016, compared with $39 million in 2015. The 2015 costs primarily consisted of Employee training and certain expenses associated with the grounding and conversion costs resulting from the transition of the Company's Boeing 717-200 fleet ("B717s") to Delta Air Lines ("Delta"). See Note 7 to the Consolidated Financial Statements for further information.

Other operating expenses for 2016 increased by $272 million, or 12.1 percent, compared with 2015. On a per ASM basis, Other operating expenses for 2016 increased 6.9 percent, compared with 2015. On both a dollar and per ASM basis, approximately 30 percent of the increase was due to higher contract programming and consulting expenses associated with large technology projects and approximately 15 percent of the increase was due to increased personnel expenses. Other operating expenses for 2016 also increased as the result of a $37 million litigation settlement received during 2015 which reduced 2015 Other operating expenses, a $22 million lease termination expense as a result of the Company acquiring five of its Boeing 737-300 aircraft off operating leases, and a $21 million increase due to an impairment charge related to leased slots at Newark Liberty International Airport. The remainder was due to revenue related costs driven by the 5.5 percent increase in Revenue Passengers Carried. The Company currently expects Other operating expenses per ASM for first quarter 2017 to increase, compared with first quarter 2016.

Other

Other expenses (income) include interest expense, capitalized interest, interest income, and other gains and losses.

Interest expense for 2016 increased $1 million, or 0.8 percent, compared with 2015, primarily due to the timing of debt issuances and payoffs in 2015 and 2016.

Capitalized interest for 2016 increased $16 million, or 51.6 percent, compared with 2015, primarily due to an increase in average progress payment balances for scheduled future aircraft deliveries.


42


Interest income for 2016 increased $15 million, or 166.7 percent, compared with 2015, primarily due to higher interest rates coupled with a greater amount of interest earned on cash collateral held by counterparties. See Note 10 to the Consolidated Financial Statements for further information on the Company's derivatives.

Other (gains) losses, net, primarily includes amounts recorded as a result of the Company's hedging activities. See Note 10 to the Consolidated Financial Statements for further information on the Company's hedging activities.

Income Taxes

The Company's effective tax rate was 36.8 percent for 2016, compared with 37.3 percent for 2015 primarily due to a decrease in State taxes owed and the Company's adoption of Accounting Standards Update 2016-09. See Note 2 to the Consolidated Financial Statements for further information. The Company currently projects a full year 2017 effective tax rate of approximately 37 percent based on currently forecasted financial results.

2015 Compared with 2014

Operating Revenues

Passenger revenues for 2015 increased by $641 million, or 3.6 percent, compared with 2014. Holding load factor and yield constant, the increase was primarily attributable to a 7.2 percent increase in capacity as strong Customer demand for low-fare air travel enabled the Company to fill the additional seats, as evidenced by a Company annual load factor of 83.6 percent. On a unit basis, Passenger revenue decreased 3.4 percent, year-over-year, largely driven by a 4.7 percent decrease in passenger revenue yield, year-over-year.

Freight revenues for 2015 increased by $4 million, or 2.3 percent, compared with 2014, primarily due to increased pounds shipped.


The Company recorded a Special revenue adjustment during 2015 of $172 million. This adjustment represented a one-time non-cash reduction to the deferred revenue liability as a result of the Agreement with Chase and the resulting change in accounting methodology. The adjustment is classified as a special item and thus excluded from the Company's non-GAAP financial results. See Note 1 to the Consolidated Financial Statements and the Note Regarding Use of Non-GAAP Financial Measures for further information.


Other revenues for 2015 increased by $398 million, or 51.6 percent, compared with 2014, primarily as a result of the Agreement with Chase and the resulting change in accounting methodology. Ancillary revenues increased slightly year-over-year, primarily due to an increase in EarlyBird Check-in® and A1-15 select boarding positions sold at the gate, which was partially offset by the decrease in revenues from the termination of AirTran passenger service and related ancillary fees.

Operating Expenses


43


Operating expenses for 2015 decreased by $676 million, or 4.1 percent, compared with 2014, while capacity increased 7.2 percent over the same period. Historically, except for changes in the price of fuel, changes in Operating expenses for airlines are driven by changes in capacity, or ASMs. The following table presents the Company's Operating expenses per ASM for 2015 and 2014, followed by explanations of these changes on a per ASM basis and/or on a dollar basis:

Operating expenses per ASM for 2015 decreased by 10.6 percent, compared with 2014, primarily due to a decrease in Fuel and oil expense, partially offset by an increase in Salaries, wages, and benefits expense. On a non-GAAP basis, Operating expenses per ASM for 2015, excluding fuel and special items, increased 0.1 percent year-over-year primarily due to higher Salaries, wages, and benefits expense. See the previous Note Regarding Use of Non-GAAP Financial Measures.

Salaries, wages, and benefits expense for 2015 increased by $949 million, or 17.5 percent, compared with 2014. Salaries, wages, and benefits expense per ASM for 2015 increased 9.7 percent, compared with 2014. On both a dollar and per ASM basis, approximately half of these increases were the result of higher salaries primarily due to the accrued $334 million of union bonuses as a result of ongoing negotiations with various workgroups during 2015, increased training, additional headcount, and contractual increases. The remaining increase was primarily due to higher profitsharing expense as a result of significantly higher profits in 2015.


Fuel and oil expense for 2015 decreased by $1.7 billion, or 31.7 percent, compared with 2014. On a per ASM basis, Fuel and oil expense for 2015 decreased 36.1 percent, compared with 2014. Excluding the impact of fuel hedge accounting, both the dollar and per ASM decreases were attributable to lower jet fuel prices. The Company's average economic jet fuel price per gallon decreased 29.1 percent year-over-year, from $2.92 for 2014 to $2.07 for 2015. The Company also slightly improved fuel efficiency, when measured on the basis of ASMs generated per gallon of fuel, primarily as a result of modernization of the Company's fleet and a 4.0 percent increase in stage length. Fuel gallons consumed increased 5.6 percent, compared with 2014, while year-over-year capacity increased 7.2 percent.

As a result of the Company's fuel hedging program, the Company recognized losses totaling $254 million in Fuel and oil expense for 2015, compared with net gains totaling $28 million for 2014. These totals include cash settlements realized from the settlement of fuel derivative contracts totaling $577 million paid to counterparties for 2015, compared to $56 million received from counterparties for 2014, although such totals exclude gains and/or losses recognized from hedge ineffectiveness and from derivatives that do not qualify for hedge accounting. These impacts are recorded as a component of Other (gains) losses, net.

Maintenance materials and repairs expense for 2015 increased by $27 million, or 2.8 percent, compared with 2014. On a per ASM basis, Maintenance materials and repairs expense for 2015 decreased 4.0 percent, compared with 2014, as the dollar increases were more than offset by the 7.2 percent increase in capacity. On a dollar basis, the majority of the increase was attributable to the timing of regular airframe maintenance checks, partially offset by reduced engine and avionic repair expense as a result of the B717 aircraft transitioning out of the Company's fleet.

44



Aircraft rentals expense for 2015 decreased by $57 million, or 19.3 percent, compared with 2014. On a per ASM basis, Aircraft rentals expense decreased 22.7 percent, compared with 2014. On both a dollar and per ASM basis, the decrease was primarily due to the transition of leased B717 aircraft out of the Company's fleet for conversion and delivery to Delta.

Landing fees and other rentals expense for 2015 increased by $55 million, or 5.0 percent, compared with 2014. On a per ASM basis, Landing fees and other rentals expense for 2015 decreased 2.4 percent, compared with 2014, as the dollar increases were more than offset by the 7.2 percent increase in capacity. On a dollar basis, the majority of the increase was due was due to higher space rental rates at various airports. The remaining increase was due to heavier landing weights for the Company's higher capacity 737-800 aircraft.

Depreciation and amortization expense for 2015 increased by $77 million, or 8.2 percent, compared with 2014. On a per ASM basis, Depreciation and amortization expense remained flat, compared with 2014. On a dollar basis, the majority of the increase was due to the purchase and capital lease of new and used aircraft since 2014, the majority of which replaced B717s removed from service in late 2014.

The Company incurred $39 million in Acquisition and integration costs in 2015, related to the AirTran integration, compared with $126 million in 2014. This expense primarily consisted of Employee training, facilities integration, and certain expenses associated with the grounding and conversion costs resulting from the transition of B717s to Delta.

Other operating expenses for 2015 increased by $37 million, or 1.7 percent, compared with 2014. On a per ASM basis, Other operating expenses for 2015 decreased 5.4 percent, compared with 2014, as the dollar increases were more than offset by the 7.2 percent increase in capacity. On a dollar basis, the increase was equally attributable to higher personnel expenses associated with travel costs of the Company's flight crew and credit card fees paid to third parties associated with the increase in Passenger revenues. These and other smaller increases were partially offset by a decrease in security expenses as a result of the repeal of the TSA Aviation Security Infrastructure Fee in October 2014 and a litigation settlement received by the Company in the first quarter of 2015.

Note Regarding Use of Non-GAAP Financial Measures

The Company's Consolidated Financial Statements are prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). These GAAP financial statements include (i) unrealized non-cash adjustments and reclassifications, which can be significant, as a result of accounting requirements and elections made under accounting pronouncements relating to derivative instruments and hedging and (ii) other charges and benefits the Company believes are unusual and/or infrequent in nature and thus may not be indicative of its ongoing operational performance.

As a result, the Company also provides financial information in this filing that was not prepared in accordance with GAAP and should not be considered as an alternative to the information prepared in accordance with GAAP. The Company provides supplemental non-GAAP financial information, including results that it refers to as "economic," which the Company's management utilizes to evaluate its ongoing financial performance and the Company believes provides additional insight to investors as supplemental information to its GAAP results. The non-GAAP measures provided that relate to the Company’s performance on an economic fuel cost basis include Fuel and oil expense, non-GAAP; Total operating expenses, non-GAAP; Operating income, non-GAAP; Net income, non-GAAP; and Net income per share, diluted, non-GAAP. The Company's economic Fuel and oil expense results differ from GAAP results in that they only include the actual cash settlements from fuel hedge contracts - all reflected within Fuel and oil expense in the period of settlement. Thus, Fuel and oil expense on an “economic” basis has historically been utilized by the Company, as well as some of the other airlines that utilize fuel hedging, as it reflects the Company’s actual net cash outlays for fuel during the applicable period, inclusive of settled fuel derivative contracts. Any net premium costs paid related to option contracts are reflected as a component of Other (gains) losses, net, for both GAAP and non-GAAP (including economic) purposes in the period of contract settlement. The Company believes these economic results provide a better measure of the impact of the Company's fuel hedges on its operating performance and liquidity since they exclude the unrealized, non-cash adjustments and reclassifications that are recorded in GAAP results in accordance with accounting guidance relating to derivative instruments, and they reflect all cash settlements related to fuel derivative contracts within Fuel and oil expense. This enables the Company's management, as well as investors and analysts, to consistently assess the Company's operating performance on a year-over-year or quarter-over-quarter basis after considering all efforts in place to manage fuel expense. However, because these measures are not determined in accordance with GAAP, such measures are susceptible to varying calculations, and not all companies calculate the measures in the same manner. As a result, the aforementioned measures, as presented, may not be directly comparable to similarly titled measures presented by other companies.

Further information on (i) the Company's fuel hedging program, (ii) the requirements of accounting for derivative instruments, and (iii) the causes of hedge ineffectiveness and/or mark-to-market gains or losses from derivative instruments is included in Note 10 to the Consolidated Financial Statements.

In addition, the Company’s GAAP results in the applicable periods include other charges or benefits that are deemed “special items” that the Company believes are not indicative of its ongoing operations and make its results difficult to compare to prior periods, anticipated future periods, or to its competitors’ results. Financial measures identified as non-GAAP (or as excluding special items) have been adjusted to exclude special items. Special items include:
1.
A one-time $172 million Special revenue adjustment in July 2015 as a result of the Agreement with Chase and the resulting required change in accounting methodology. This increase to revenue represented a nonrecurring required acceleration of revenues associated with the adoption of Accounting Standards Update 2009-13;
2.
Union contract bonuses recorded for certain workgroups. As the bonuses would only be paid at ratification of the associated tentative agreement and would not represent an ongoing expense to the Company, management believes its results for the associated periods are more usefully compared if the impacts of ratification bonus amounts are excluded from results. Generally, union contract agreements cover a specified three- to five- year period, although such contracts officially never expire, and the agreed upon terms remain in place until a revised agreement is reached, which can be several years following the amendable date;
3.
Expenses associated with the Company’s acquisition and integration of AirTran. Such expenses were primarily incurred during the acquisition and integration period of the two companies from 2011 through 2015 as a result

48


of the Company’s acquisition of AirTran, which closed on May 2, 2011. The exclusion of these expenses provides investors with a more applicable basis with which to compare results in future periods now that the integration process has been completed;
4.
A gain resulting from a litigation settlement received in January 2015. This cash settlement meaningfully lowered Other operating expenses during the applicable period and the Company does not expect a similar impact on its cost structure in the future;
5.
A noncash impairment charge related to leased slots at Newark Liberty International Airport as a result of the FAA announcement in April 2016 that this airport was being changed to a Level 2 schedule-facilitated airport from its previous designation as Level 3; and
6.
Lease termination costs recorded during 2016 as a result of the Company acquiring five of its Boeing 737-300 aircraft off operating leases, as part of the Company’s strategic effort to phase out its Classic aircraft from operations by the end of third quarter 2017 in the most economically advantageous manner possible. The Company had not budgeted for these early lease termination costs, as they were subject to negotiations being concluded with the third party lessors. The Company recorded the fair value of the aircraft, as well as any associated remaining obligations to the balance sheet as debt.

Because management believes each of these items can distort the trends associated with the Company’s ongoing performance as an airline, the Company believes that evaluation of its financial performance can be enhanced by a supplemental presentation of results that exclude the impact of these items in order to enhance consistency and comparativeness with results in prior periods that do not include such items and as a basis for evaluating operating results in future periods. The following measures are often provided, excluding special items, and utilized by the Company’s management, analysts, and investors to enhance comparability of year-over-year results, as well as to compare results to other airlines: Operating revenues, non-GAAP; Total operating expenses, non-GAAP; Operating income, non-GAAP; Net income, non-GAAP; Net income per share, diluted, non-GAAP; and Operating expenses per ASM, non-GAAP, excluding fuel and special items.
 
The Company has also provided return on invested capital, which is calculated, in part, using non-GAAP financial measures. The Company believes return on invested capital is a meaningful measure because it quantifies how well the Company generates operating income relative to the capital it has invested in its business. Although return on invested capital is commonly used as a measure of capital efficiency, definitions of return on invested capital differ; therefore, the Company is providing an explanation of its calculation for return on invested capital (before taxes and excluding special items) in the accompanying reconciliation.

Liquidity and Capital Resources

Net cash provided by operating activities for 2016, 2015, and 2014 was $4.3 billion, $3.2 billion, and $2.9 billion, respectively. Operating cash inflows are primarily derived from providing air transportation to Customers. The vast majority of tickets are purchased prior to the day on which travel is provided and, in some cases, several months before the anticipated travel date. Operating cash outflows are related to the recurring expenses of airline operations. The operating cash flows for 2016, 2015, and 2014 were impacted primarily by the Company's results of operations, as adjusted for non-cash items as well as changes in the Air traffic liability and Accrued liabilities balances. Operating cash flows also can be significantly impacted by the Company’s fuel and interest rate hedge positions and the corresponding cash collateral requirements associated with those positions. The Company has the ability to post aircraft in lieu of cash collateral in certain situations. See Note 10 to the Consolidated Financial Statements for further information. During 2016, the Company had net cash inflows of $535 million in cash collateral from derivative counterparties, compared with providing $570 million and $233 million in cash collateral to derivative counterparties in 2015 and 2014, respectively. Cash flows related to the purchase of derivatives utilized to offset a portion of the Company's future fuel hedge positions prior to their settlement, as well as new fuel derivatives, which are also classified as Other, net, operating cash flows, were net outflows of $165 million in 2016, net outflows of $556 million in 2015, and net outflows of $247 million in 2014. Net cash provided by operating activities is primarily used to finance capital expenditures, repay debt, fund stock repurchases, pay dividends, and provide working capital.


49


Net cash used in investing activities for 2016, 2015, and 2014 was $2.3 billion, $1.9 billion, and $1.7 billion, respectively. Investing activities in 2016, 2015, and 2014 included payments for new aircraft delivered to the Company, progress payments for future aircraft deliveries, and purchases and sales of short-term and noncurrent investments, which fluctuate primarily based on anticipated working capital needs. Investing activities in 2016, 2015, and 2014 also included payments associated with airport construction projects, denoted as Assets constructed for others. See Note 4 to the Consolidated Financial Statements for further information. During 2016, the Company's purchases and sales of short-term and noncurrent investments resulted in net cash used of $125 million, compared with net cash provided of $237 million and $105 million in 2015 and 2014, respectively. The Company currently estimates its 2017 capital expenditures will be approximately $2.3 billion.

Net cash used in financing activities for 2016, 2015, and 2014 was $1.9 billion, $1.0 billion, and $1.2 billion, respectively. During 2016, the Company repaid $591 million in debt, convertible notes, and capital lease obligations, compared with $213 million and $561 million during 2015 and 2014, respectively. During 2016, the Company borrowed $215 million under a secured term loan agreement and, under its shelf registration statement, issued $300 million 3.00 percent senior unsecured notes due 2026, compared with the 2015 issuance of $500 million 2.65 percent senior unsecured notes due 2020 under its shelf registration statement, and the 2014 issuance of $300 million 2.75 percent senior unsecured notes due 2019 under its shelf registration statement. See Note 6 to the Consolidated Financial Statements for further information. The Company repurchased approximately $1.8 billion of its outstanding common stock through authorized share repurchases during 2016, compared with repurchases of $1.2 billion and $955 million during 2015 and 2014, respectively. The Company also paid $222 million in dividends to Shareholders during 2016, compared with $180 million in 2015 and $139 million in 2014. Although the Company currently intends to continue paying dividends on a quarterly basis for the foreseeable future, the Company's Board of Directors may change the timing, amount, and payment of dividends on the basis of results of operations, financial condition, cash requirements, future prospects, and other factors deemed relevant by the Board of Directors.

The Company is a “well-known seasoned issuer” and currently has an effective shelf registration statement registering an indeterminate amount of debt and equity securities for future sales. The Company currently intends to use the proceeds from any future securities sales off this shelf registration statement for general corporate purposes.

The Company has access to a $1 billion unsecured revolving credit facility expiring in August 2021. The revolving credit agreement has an accordion feature that would allow the Company, subject to, among other things, the procurement of incremental commitments, to increase the size of the facility to $1.5 billion. Interest on the facility is based on the Company's credit ratings at the time of borrowing. At the Company's current ratings, the interest cost would be LIBOR plus a spread of 112.5 basis points. The facility contains a financial covenant requiring a minimum coverage ratio of adjusted pre-tax income to fixed obligations, as defined. As of December 31, 2016, the Company was in compliance with this covenant and there were no amounts outstanding under the revolving credit facility.

As of May 4, 2016, the Company completed its previously authorized $1.5 billion share repurchase program, bringing in a total of 37.3 million shares over the course of the program. On May 18, 2016, the Company's Board of Directors approved a new $2.0 billion share repurchase program. Following the Board of Directors' authorization of the Company's new $2.0 billion share repurchase program, the Company entered into the following share repurchases:

The Company maintained its investment grade credit ratings of "Baa1" with Moody's, "BBB+" with Fitch, and "BBB" with Standard & Poor's.

The Company has a large net deferred tax liability on its Consolidated Balance Sheet. The deferral of income taxes has resulted in a significant benefit to the Company and its liquidity position. Since the Company purchases the majority of the aircraft it acquires, it has been able to utilize accelerated depreciation methods (including bonus depreciation) available under the Internal Revenue Code of 1986, as amended, in 2016 and in previous years, which has enabled the Company to defer the cash tax payments associated with these depreciable assets to future years. Based on the Company’s scheduled future aircraft deliveries from Boeing and existing tax laws in effect, the Company will continue to defer a portion of cash income taxes to future years. The Company has paid in the past, and will continue to pay in the future, significant cash taxes to the various taxing jurisdictions where it operates. The Company expects to be able to continue to meet such obligations utilizing cash and investments on hand, as well as cash generated from its ongoing operations.

Off-Balance Sheet Arrangements, Contractual Obligations, and Contingent Liabilities and Commitments

The Company has contractual obligations and commitments primarily with regard to future purchases of aircraft, payment of debt, and lease arrangements. During second quarter 2016, the Company revised its future firm aircraft order book. Firm deliveries previously scheduled between 2019 and 2022 were deferred to 2023 through 2025 in the restructured order book. This resulted in a $1.9 billion deferral of capital spending beyond 2020. During 2016, the Company also exercised nine 737-800 options for 2018. For aircraft commitments with Boeing, the Company is required to make cash deposits toward the purchase of aircraft in advance. These deposits are classified as Deposits on flight equipment purchase contracts in the Consolidated Balance Sheet until the aircraft is delivered, at which time deposits previously made are deducted from the final purchase price of the aircraft and are reclassified as Flight equipment. See Note 4 to the Consolidated Financial Statements for a complete table of the Company’s firm deliveries and options for Boeing 737-700, 737-800, 737-7, and 737-8 aircraft.

The leasing of aircraft (including the sale and leaseback of aircraft) provides flexibility to the Company as a source of financing. Although the Company is responsible for all maintenance, insurance, and expense associated with operating leased aircraft, and retains the risk of loss for these aircraft, it has not made guarantees to the lessors regarding the residual value (or market value) of the aircraft at the end of the lease terms. As of December 31, 2016, the Company had 212 leased aircraft, including 78 B717s subleased to Delta. Of these leased aircraft, 159 are under operating leases, including 76 B717s subleased to Delta. See Note 7 to the Consolidated Financial Statements for further information on this transaction. Assets and obligations under operating leases are not included in the Company’s Consolidated Balance Sheet. Disclosure of the contractual obligations associated with the Company’s leased aircraft is included below.

The Company is required to provide standby letters of credit to support certain obligations that arise in the ordinary course of business and may choose to provide letters of credit in place of posting cash collateral related to its fuel hedging positions. Although the letters of credit are off-balance sheet, the majority of the obligations to which they relate are reflected as liabilities in the Consolidated Balance Sheet. Outstanding letters of credit totaled $179 million at December 31, 2016.

The Company believes that its current liquidity position, including unrestricted cash and short-term investments of $3.3 billion as of December 31, 2016, anticipated future internally generated funds from operations, and its fully available, unsecured revolving credit facility of $1.0 billion that expires in August 2021, will enable it to meet its future known obligations in the ordinary course of business. The revolving credit agreement has an accordion feature that would allow the Company, subject to, among other things, the procurement of incremental commitments, to increase the size of the facility to $1.5 billion. However, if a liquidity need were to arise, the Company believes it has access to financing arrangements because of its current investment grade credit ratings, large value of unencumbered assets, and modest leverage, which should enable it to meet its ongoing capital, operating, and other liquidity requirements. The Company will continue to consider various borrowing or leasing options to maximize liquidity and supplement cash requirements as necessary.

Airport Projects

The Company has commitments associated with various airport improvement projects that will impact its future liquidity needs in differing ways. These projects include the construction of new facilities and the rebuilding or modernization of existing facilities and are discussed in more detail in Note 4 to the Consolidated Financial Statements.

Dallas Love Field
For the rebuilding of the facilities at Dallas Love Field, the Company guaranteed principal, premium, and interest on $456 million in bonds issued by the Love Field Airport Modernization Corporation (“LFAMC”) that were utilized to fund the majority of the project. The amount of bonds outstanding as of December 31, 2016 was $432 million. Repayment of the bonds is through the “Facilities Payments” described below. Reimbursement of the Company for its payment of Facilities Payments is made through recurring ground rents, fees, and other revenues collected at the airport.
Prior to the issuance of the bonds by the LFAMC, the Company entered into two separate funding agreements: (i) a “Facilities Agreement” pursuant to which the Company is obligated to make debt service payments on the principal and interest amounts associated with the bonds ("Facilities Payments"), less other sources of funds the City of Dallas may apply to the repayment of the bonds (including but not limited to passenger facility charges collected from

52


passengers originating from the airport); and (ii) a “Revenue Credit Agreement” pursuant to which the City of Dallas reimburses the Company for the Facilities Payments made by the Company.
A majority of the monies transferred from the City of Dallas to the Company under the Revenue Credit Agreement originate from a reimbursement account created in the “Use and Lease Agreement” between the City of Dallas and the Company. The Use and Lease Agreement is a 20-year agreement providing for, among other things, the Company’s lease of space at the Airport from the City of Dallas. The remainder of such monies transferred from the City of Dallas to the Company under the Revenue Credit Agreement originates from (i) use and lease agreements with other airlines, (ii) various concession agreements, and (iii) other airport miscellaneous revenues.
The Company’s liquidity could be impacted by this project to the extent there are timing differences between the Company’s payment of the Facilities Payments pursuant to the Facilities Agreement and the transfer of monies back to the Company pursuant to the Revenue Credit Agreement; however, the Company does not currently expect that to occur. The project has not had a significant impact on the Company’s capital resources or financial position.
Fort Lauderdale-Hollywood International Airport
The Company has committed to oversee and manage the design and construction of Fort-Lauderdale-Hollywood International Airport's Terminal 1 Modernization Project, including the design and construction of a new five-gate Concourse A with an international processing facility, at a cost not to exceed $333 million. Funding for the project has come directly from Broward County aviation sources, but flows through the Company in its capacity as manager of the project. In general, as work is being completed on the project by various contractors, invoices are submitted to Broward County for initial payment to the Company, which then make such payments to the contractors performing the work.
The Company’s liquidity could be impacted by this project to the extent there are instances in which the Company chooses to make payments to contractors prior to receiving initial payment from Broward County, although the Company currently does not expect this to occur often based on its past experience with smaller projects conducted at the airport. The project is not expected to have a significant impact on the Company’s capital resources or financial position. Major construction on the project began during third quarter 2015 and is estimated to be substantially completed by mid-2017.
Houston William P. Hobby Airport
The Company oversaw and managed the construction, at Houston William P. Hobby Airport, of a new five-gate international terminal with international passenger processing facilities, expansion of the existing security checkpoint, and upgrades to the Southwest ticketing counter area. The Company and the City of Houston ("City") entered into an Airport Use and Lease Agreement ("Lease") to control the execution of this expansion and the financial terms thereof. The project cost approximately $150 million, of which $22 million was considered proprietary and thus not classified as Assets constructed for others. The Company provided the funding for, and management over, the project. In return, the capital cost portion of the rent the Company pays for the international facility is waived from the initial occupancy until the expiration of the Lease. However, the City has the option at any time during the term of the Lease to reimburse the Company's investment at the then-unamortized cost of the facility. This purchase would trigger payment of the previously waived capital cost component of rents owed the City. Additionally, a small portion of the project qualified for rental credits that have been utilized against a portion of the Company’s 2016 lease payments at the airport.
The Company’s liquidity has been impacted by this project from the point of initial funding through the time at which it receives monthly credits, and whether or not the City chooses to buy out the Company’s investment prior to the full amortization of the project. The project did not have a significant impact on the Company’s capital resources or financial position. Construction began during third quarter 2013 and was effectively completed in October 2015, at which time the Company began operating from the new facility.
Los Angeles International Airport
In March 2013, the Company executed a lease agreement with Los Angeles World Airports (“LAWA”), which owns and operates Los Angeles International Airport. Under the lease agreement, which was amended in June 2014, the

53


Company is overseeing and managing the design, development, financing, construction, and commissioning of the airport's Terminal 1 Modernization Project (the “Project”) at a cost not to exceed $526 million. The Project is being funded primarily using the Regional Airports Improvement Corporation ("RAIC"), which is a quasi-governmental special purpose entity that acts as a conduit borrower under a syndicated credit facility provided by a group of lenders. Loans made under the credit facility are being used to fund the development of the Project, and the outstanding loans will be repaid with the proceeds of LAWA’s payments to purchase completed Project phases. The Company has guaranteed the obligations of the RAIC under the credit facility. 
The Company’s liquidity could be impacted by this project under certain circumstances; however, the Company does not expect this to occur based on its past experience with other projects. The project is not expected to have a significant impact on the Company’s capital resources or financial position. Construction on the Project began during 2014 and is estimated to be completed during 2018.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The Company’s Consolidated Financial Statements have been prepared in accordance with GAAP. The Company’s significant accounting policies are described in Note 1 to the Consolidated Financial Statements. The preparation of financial statements in accordance with GAAP requires the Company’s management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying footnotes. The Company’s estimates and assumptions are based on historical experience and changes in the business environment. However, actual results may differ from estimates under different conditions, sometimes materially. Critical accounting policies and estimates are defined as those that both (i) are most important to the portrayal of the Company’s financial condition and results and (ii) require management’s most subjective judgments. The Company’s most critical accounting policies and estimates are described below.

Revenue Recognition

Tickets sold for Passenger air travel are initially deferred as Air traffic liability. Passenger revenue is recognized and Air traffic liability is reduced when the service is provided (i.e., when the flight takes place). Air traffic liability primarily represents tickets sold for future travel dates and funds that are past flight date and remain unused. The balance in Air traffic liability, which includes a portion of the Company’s liability associated with its frequent flyer program, fluctuates throughout the year based on seasonal travel patterns, fare sale activity, and activity associated with the Company’s frequent flyer program.

For air travel on Southwest, the amount of tickets that will expire unused are estimated and recognized in Passenger revenue once the scheduled flight date has passed. Estimating the amount of tickets that will expire unused involves some level of subjectivity and judgment. The majority of Southwest’s tickets sold are nonrefundable, which is the primary source of unused tickets. Southwest has a No Show policy that applies to nonrefundable fares that are not canceled or changed by a Customer at least ten minutes prior to a flight's scheduled departure. See Note 1 to the Consolidated Financial Statements for further information. According to Southwest’s current “Contract of Carriage,” all refundable tickets that are sold but not flown on the travel date can be reused for another flight up to a year from the date of sale, or some tickets can be refunded. This policy also applies to unused Customer funds that may be the result of an exchange downgrade. Fully refundable tickets rarely expire unused. Estimates of tickets that will expire unused are based on historical experience over many years. Southwest has consistently applied this accounting method to estimate revenue from unused tickets at the date of scheduled travel.

Events and circumstances outside of historical fare sale activity or historical Customer travel patterns can result in actual spoiled tickets differing significantly from estimates. The Company evaluates its estimates within a narrow range of acceptable amounts. If actual spoilage results in an amount outside of this range, estimates and assumptions are reviewed and adjustments to Air traffic liability and to Passenger revenue are recorded, as necessary. Additional factors that may affect estimated spoiled tickets include, but may not be limited to, changes to the Company’s ticketing policies, the Company’s refund, exchange, and unused funds policies, the mix of refundable and nonrefundable fares, promotional fare activity, and the impact of the economic environment on Customer behavior. The Company’s

54


estimation techniques have been consistently applied from year to year; however, as with any estimates, actual spoiled tickets may vary from estimated amounts. During 2014, the Company revised assumptions regarding Customer behavior subsequent to the implementation of its No Show policy. Consequently, the Company’s estimate of the amount of spoiled tickets recorded during 2014 was approximately 15 percent higher than what it believed its historical averages would indicate for that year. The Company believes the change in policy resulted in a permanent shift in Customer behavior for 2014 and all subsequent periods, barring any future modifications to the Company's ticketing policies. The Company believes these estimates are supported by actual data and are reasonable given the underlying fact patterns.

The Company believes it is unlikely that materially different estimates for future spoiled tickets would be reported based on other reasonable assumptions or conditions suggested by actual historical experience and other data available at the time estimates were made.

Accounting for Long-Lived Assets

Flight equipment and related assets make up the majority of the Company’s long-lived assets. Flight equipment primarily relates to the 640 Boeing 737 aircraft in the Company’s fleet at December 31, 2016, which are either owned or on capital lease. The remaining 83 Boeing 737 aircraft in the Company’s fleet at December 31, 2016, are operated under operating leases. The Company also has 88 Boeing 717 aircraft, which are part of the lease/sublease with Delta. As these aircraft are not in service for the Company, they are not included in the fleet count as of December 31, 2016 or 2015. See Note 7 to the Consolidated Financial Statements for further information. In accounting for long-lived assets, the Company must make estimates about the expected useful lives of the assets, the expected residual values of the assets, and the potential for impairment based on the fair value of the assets and their future expected cash flows.

The following table shows a breakdown of the Company’s long-lived asset groups along with information about estimated useful lives and residual values for new assets generally purchased from the manufacturer and assets constructed for others:
 
 
 
Estimated useful life         
 
Estimated
  residual value  
Airframes and engines
 
23 to 25 years
 
2 to 20 percent
Aircraft parts
 
Fleet life
 
4 percent
Assets constructed for others
 
25 to 30 years
 
17 to 25 percent
Ground property and equipment
 
5 to 30 years
 
0 to 10 percent

In estimating the lives and expected residual values of its aircraft, the Company primarily has relied upon actual experience with the same or similar aircraft types, current and projected future market information, and recommendations from Boeing. Aircraft estimated useful lives are based on the number of “cycles” flown (one take-off and landing) as well as the aircraft age. The Company has made a conversion of cycles into years based on both historical and anticipated future utilization of the aircraft. Subsequent revisions to these estimates, which can be significant, could be caused by changes to aircraft maintenance programs, changes in utilization of the aircraft (actual cycles during a given period of time), governmental regulations on aging aircraft, and changing market prices of new and used aircraft of the same or similar types. The Company evaluates its estimates and assumptions each reporting period and, when warranted, adjusts these estimates and assumptions. For example, during 2016, the Company accelerated the estimated retirement dates of its Classic 737 fleet from mid-2021 to no later than third quarter 2017, resulting in an additional $123 million in depreciation expense recorded during the year. Generally, these adjustments are accounted for on a prospective basis through depreciation and amortization expense. See Notes 1 and 2 to the Consolidated Financial Statements for further information.

The Company believes it is unlikely that materially different estimates for expected lives, expected residual values, and impairment evaluations would be made or reported based on other reasonable assumptions or conditions suggested by actual historical experience and other data available at the time estimates were made.

Financial Derivative Instruments

The Company utilizes financial derivative instruments primarily to manage its risk associated with changing jet fuel prices. See “Quantitative and Qualitative Disclosures about Market Risk” for more information on these risk management activities, and see Note 10 to the Consolidated Financial Statements for more information on the Company’s fuel hedging program and financial derivative instruments.

All derivatives are required to be reflected at fair value and recorded on the Consolidated Balance Sheet. At December 31, 2016, the Company was a party to over 500 separate financial derivative instruments related to its fuel hedging program for the years 2017 through 2019. Changes in the fair values of these instruments can vary dramatically based on changes in the underlying commodity prices. For example, during 2016, market “spot” prices for Brent crude oil peaked at a high of approximately $57 per barrel and hit a low price of approximately $28 per barrel. During 2015, market spot prices ranged from a high of approximately $68 per barrel to a low of approximately $36 per barrel. Market price changes can be driven by factors such as supply and demand, inventory levels, weather events, refinery capacity, political agendas, the value of the U.S. dollar, geopolitical events, and general economic conditions, among other items. The financial derivative instruments utilized by the Company primarily are a combination of collars, purchased call options, call spreads, put spreads, and fixed price swap agreements.

The Company enters into financial derivative instruments with third party institutions in “over-the-counter” markets. Since the majority of the Company’s financial derivative instruments are not traded on a market exchange, the Company estimates their fair values. Depending on the type of instrument, the values are determined by the use of present value methods or standard option value models with assumptions about commodity prices based on those observed in underlying markets. Also, since there is not a reliable forward market for jet fuel beyond approximately 24 months, the Company must estimate the future prices of jet fuel in order to measure the effectiveness of the hedging instruments in offsetting changes to those prices. Forward jet fuel prices are estimated through the observation of similar commodity futures prices (such as crude oil, heating oil, and unleaded gasoline) and adjusted based on variations of those like commodities to the Company’s ultimate expected price to be paid for jet fuel at the specific locations in which the Company hedges.

Fair values for financial derivative instruments and forward jet fuel prices are estimated prior to the time that the financial derivative instruments settle and the time that jet fuel is purchased and consumed, respectively. However, once settlement of the financial derivative instruments occurs and the hedged jet fuel is purchased and consumed, all values and prices are known and are recognized in the financial statements. Although the Company continues to use a prospective assessment to determine that commodities continue to qualify for hedge accounting in specific locations where the Company hedges, there are no assurances that these commodities will continue to qualify in the future. This is due to the fact that future price changes in these refined products may not be consistent with historical price changes. Increased volatility in these commodity markets for an extended period of time, especially if such volatility were to worsen, could cause the Company to lose hedge accounting altogether for the commodities used in its fuel hedging program, which would create further volatility in the Company’s GAAP financial results.

Estimating the fair value of these fuel derivative instruments and forward prices for jet fuel will also result in changes in their fair values from period to period and thus determine their accounting treatment. To the extent that the change in the estimated fair value of a fuel derivative instrument differs from the change in the estimated price of the associated jet fuel to be purchased, both on a cumulative and a period-to-period basis, ineffectiveness of the fuel hedge can result. This could result in the immediate recording of non-cash charges or income, representing the change in the fair value of the derivative, even though the derivative instrument may not expire/settle until a future period. Likewise, if a derivative contract ceases to qualify for hedge accounting, the change in the fair value of the derivative instrument is recorded every period to Other (gains) and losses, net in the Consolidated Statement of Income in the period of the change.

Ineffectiveness is inherent in hedging jet fuel with derivative positions based in other crude oil related commodities, especially given the past volatility in the prices of refined products. Due to the volatility in markets for crude oil and related products, the Company is unable to predict the amount of ineffectiveness each period, including the loss of

56


hedge accounting, which could be determined on a derivative by derivative basis or in the aggregate for a specific commodity. This may result, and has historically resulted, in increased volatility in the Company’s financial statements. The amount of hedge ineffectiveness and unrealized gains and losses due to the change in fair value of derivative contracts settling in future periods, recorded during historical periods, has been due to a number of factors. These factors include: the significant fluctuation in energy prices, the number of derivative positions the Company holds, significant weather events that have affected refinery capacity and the production of refined products, and the volatility of the different types of products the Company uses for mitigation of fuel price volatility. The discontinuation of hedge accounting for specific hedges and for specific refined products, such as unleaded gasoline, can also be a result of these factors. Depending on the level at which the Company is hedged at any point in time, as the fair value of the Company’s hedge positions fluctuate in amount from period to period, there could be continued variability recorded in the Consolidated Statement of Income, and furthermore, the amount of hedge ineffectiveness and unrealized gains or losses recorded in earnings may be material. This is primarily because small differences in the correlation of crude oil related products could be leveraged over large volumes.

The Company continually looks for better and more accurate methodologies in forecasting expected future cash flows relating to its jet fuel hedging program. These estimates are an important component used in the measurement of effectiveness for the Company’s fuel hedges. The current methodology used by the Company in forecasting forward jet fuel prices is primarily based on the idea that different types of commodities are statistically better predictors of forward jet fuel prices, depending on specific geographic locations in which the Company hedges. The Company then adjusts for certain items, such as transportation costs, that are stated in fuel purchasing contracts with its vendors, in order to estimate the actual price paid for jet fuel associated with each hedge. This methodology for estimating expected future cash flows (i.e., jet fuel prices) has been consistently applied during 2016, 2015, and 2014, and has not changed for either assessing or measuring hedge ineffectiveness during these periods.

The Company believes it is unlikely that materially different estimates for the fair value of financial derivative instruments and forward jet fuel prices would be made or reported based on other reasonable assumptions or conditions suggested by actual historical experience and other data available at the time estimates were made.

Fair Value Measurements

The Company utilizes unobservable (Level 3) inputs in determining the fair value of certain assets and liabilities. At December 31, 2016, these consisted of a portion of its fuel derivative option contracts, which were a net liability of $258 million.

The Company determines the fair value of fuel derivative option contracts utilizing an option pricing model based on inputs that are either readily available in public markets, can be derived from information available in publicly quoted markets, or are quoted by its counterparties. In situations where the Company obtains inputs via quotes from its counterparties, it verifies the reasonableness of these quotes via similar quotes from another counterparty as of each date for which financial statements are prepared. The Company has consistently applied these valuation techniques in all periods presented and believes it has obtained the most accurate information available for the types of derivative contracts it holds. Due to the fact that certain inputs used in determining estimated fair value of its option contracts are considered unobservable (primarily implied volatility), the Company has categorized these option contracts as Level 3.

As discussed in Note 10 to the Consolidated Financial Statements, any changes in fair value of cash flow hedges that are considered to be effective, as defined, are offset within AOCI until the period in which the expected future cash flow impacts earnings. Any changes in the fair value of fuel derivatives that are ineffective, as defined, or that do not qualify for hedge accounting, are reflected in earnings within Other (gains) losses, net, in the period of the change. Because the Company has extensive historical experience in valuing the derivative instruments it holds, and such experience is continually evaluated against its counterparties each period when such instruments expire and are settled for cash, the Company believes it is unlikely that an independent third party would value the Company’s derivative contracts at a significantly different amount than what is reflected in the Company’s financial statements. In addition, the Company also has bilateral credit provisions in some of its counterparty agreements, which provide for parties (or

57


the Company) to provide cash collateral when the fair value of fuel derivatives with a single party exceeds certain threshold levels. Since this cash collateral is based on the estimated fair value of the Company’s outstanding fuel derivative contracts, this provides further validation to the Company’s estimate of fair values.

Frequent Flyer Accounting

The Company utilizes estimates in the recognition of liabilities associated with its frequent flyer program. These estimates primarily include the liability associated with Rapid Rewards frequent flyer member ("Member") account balances that are expected to be redeemed for travel or other products at a future date. Frequent flyer account balances include points earned through flights taken, points sold to Customers, or points earned through business partners participating in the frequent flyer program.

Under the Southwest Rapid Rewards frequent flyer program, Members earn points for every dollar spent. The amount of points earned under the program is based on the fare and fare class purchased, with higher fare products (e.g., Business Select) earning more points than lower fare products (e.g., Wanna Get Away). Each fare class is associated with a points earning multiplier, and points for flights are calculated by multiplying the fare for the flight by the fare class multiplier. Likewise, the amount of points required to be redeemed for a flight is based on the fare and fare class purchased. Under the program, (i) Members are able to redeem their points for every available seat, every day, on every flight, with no blackout dates; and (ii) points do not expire so long as the Rapid Rewards Member has points-earning activity during a 24-month time period. In addition, Southwest co-branded Chase Visa credit card holders are able to redeem their points for items other than travel on Southwest Airlines, such as international flights on other airlines, cruises, hotel stays, rental cars, gift cards, event tickets, and more. In addition to earning points for revenue flights and qualifying purchases with Rapid Rewards Partners, Rapid Rewards Members also have the ability to purchase, gift, and transfer points, as well as the ability to donate points to selected charities.

The Company utilizes the incremental cost method of accounting for points earned through flights taken in its frequent flyer program. Liabilities are recorded for the estimated incremental cost of providing free travel as points are being earned and companion passes earned. The liabilities recorded represent the total number of points expected to be redeemed by Members, regardless of whether the Members may have enough to qualify for a full travel award. The incremental cost liabilities are primarily composed of direct Passenger costs such as fuel, food, and other operational costs, but do not include any contribution to fixed overhead costs or profit. At December 31, 2016, the incremental cost liabilities were approximately $63 million.

The Company also sells frequent flyer points and related services to business partners participating in the frequent flyer program. The majority of the points sold to business partners are through the Southwest co-branded Chase Visa credit card. Prior to third quarter 2015, funds received from the sale of points associated with these agreements were accounted for under the residual method. Under the residual method, the Company estimated the percent of the amount received from frequent flyer points sold associated with Southwest’s co-branded Chase Visa credit card that related to free travel. The estimated amounts associated with free travel were deferred and recognized as Passenger revenue when the ultimate free travel awards were flown. During third quarter 2015, the Company executed an amended co-branded credit card agreement (“Agreement”) with Chase Bank USA, N.A. (“Chase”), which materially modified the previously existing agreement between Chase and the Company. Consideration received as part of this Agreement is subject to Accounting Standards Update ("ASU") 2009-13, Multiple-Deliverable Revenue Arrangements - a consensus of the FASB Emerging Issues Task Force. The modified Agreement has the following multiple elements: travel points to be awarded; use of the Southwest Airlines’ brand and access to Rapid Reward Member lists; advertising elements; and the Company’s resource team. Under ASU 2009-13, these deliverables are accounted for separately and allocation of consideration from the Agreement is determined based on the relative selling price of each deliverable. The application of ASU 2009-13 to the Agreement decreases the relative value of the air transportation deliverables that the Company records as deferred revenue (and ultimately Passenger revenues when redeemed awards are flown) and increases the relative value of the marketing-related deliverables recorded in Other revenues at the time these marketing-related deliverables are provided. This is principally due to the previous application of the residual method, which effectively applied the entire discount associated with the agreement to the marketing deliverables.


58


Significant management judgment was used to estimate the selling price of each of the deliverables. The objective was to determine the price at which the Company would transact a sale if the product or service was sold on a stand-alone basis. The Company determined the best estimate of selling price by considering multiple inputs and methods including, but not limited to, the estimated selling price of comparable travel, discounted cash flows, brand value, published selling prices, number of points awarded, and the number of points redeemed. The Company estimated the selling prices and volumes over the term of the Agreement in order to determine the allocation of proceeds to each of the multiple deliverables. The Company records passenger revenue related to air transportation and certificates for discounted companion travel when the transportation is delivered. A 1.0 percent increase or decrease in the Company's estimate of the standalone selling prices resulting in an allocation of proceeds to air transportation would have changed the Company's Operating revenues by less than $14 million for 2016.

The Company followed the transition approach of ASU 2009-13, which required that the Company's existing deferred revenue balance, classified within Air traffic liability, be adjusted to reflect the value, on a relative selling price basis, of any undelivered element remaining at the date of contract modification. The relative selling price of the undelivered element (air transportation) was lower than the rate at which it had been deferred under the previous contract and the Company recorded a one-time, non-cash adjustment to decrease frequent flyer deferred revenue and increase revenue through the recording of a Special revenue adjustment of $172 million. In addition, 2015 and 2016 Operating revenues increased by an estimated net $255 million and $261 million, respectively, as a result of the amended Agreement with Chase and the resulting July 1, 2015, change in accounting methodology. See Note 1 to the Consolidated Financial Statements for further information.

Under its current program, Southwest estimates the portion of frequent flyer points that will not be redeemed. In estimating spoilage, the Company takes into account the Member’s past behavior, as well as several factors related to the Member’s account that are expected to be indicative of the likelihood of future point redemption. These factors include, but are not limited to, tenure with program, points accrued in the program, and whether or not the customer has a co-branded credit card. During fourth quarter 2014, the Company obtained sufficient historical behavioral data to develop a predictive statistical model to analyze the amount of spoilage expected for points sold to business partners. The Company updates this model at least annually, and applies the new spoilage rates effective October 1st each year, or more frequently if required by changes in the business. The rate applied, as of October 1, 2014, accounted for prospectively as a change in estimate, resulted in an increase in Passenger revenue of approximately $55 million for the year ended December 31, 2014, and an increase in Passenger revenue of approximately $115 million for the first nine months of 2015. The new spoilage rates applied in 2015 and 2016 did not have a material impact to Passenger revenues during fourth quarter 2015 or full year 2016. For the year ended December 31, 2016, based on actual redemptions of points sold to business partners, a hypothetical one percentage point change in the estimated spoilage rate would have resulted in a change to Passenger revenue of approximately $40 million (an increase in spoilage would have resulted in an increase in revenue and a decrease in spoilage would have resulted in a decrease in revenue). Given that Member behavior will continue to develop as the program matures, the Company expects the current estimates may change in future periods. However, the Company believes its current estimates are reasonable given current facts and circumstances.

Goodwill and Other Intangible Assets

As a result of the Company’s acquisition of AirTran on May 2, 2011, the Company has reflected Goodwill on its Consolidated Balance Sheet in the amount of $970 million at December 31, 2016, the excess of the consideration transferred over the fair value of AirTran’s assets and liabilities on the acquisition date. In addition, the Company's other intangible assets have a net carrying amount of approximately $426 million at December 31, 2016, of which $295 million related to indefinite-lived intangible assets. Indefinite-lived assets are not amortized and primarily consist of take-off and landing slots at certain domestic slot-controlled airports. Finite-lived intangible assets include leasehold rights to airport gates and certain intangible assets recognized as a part of the valuation of AirTran and are amortized over their estimated economic useful lives. Goodwill and indefinite-lived intangible assets are not amortized, but tested for impairment annually, as of October 1st, or more frequently if events or circumstances indicate that impairment may exist.


59


The Company applies a fair value based impairment test to the carrying value of goodwill and indefinite-lived intangible assets annually on October 1st, or more frequently if certain events or circumstances indicate that an impairment loss may have been incurred. The Company assesses the value of goodwill and indefinite-lived assets under either a qualitative or quantitative approach. Under a qualitative approach, the Company considers various market factors, including applicable key assumptions listed below. These factors are analyzed to determine if events and circumstances have affected the fair value of goodwill and indefinite-lived intangible assets. If the Company determines that it is more likely than not that an indefinite-lived intangible asset is impaired, the quantitative approach is used to assess the asset’s fair value and the amount of the impairment. Under a quantitative approach, the fair value is calculated based on key assumptions listed below. If the asset’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.
When performing a quantitative impairment assessment of goodwill and indefinite-lived intangible assets, fair value is estimated based on (i) recent market transactions, where available; (ii) projected discounted cash flows (an income approach); or (iii) a combination of limited market transactions and the lease savings method (which reflects potential annual after-tax lease savings arising from owning the slots rather than leasing them from another airline at market rates).
Key assumptions and/or estimates made in the Company’s impairment tests include: (i) a projection of revenues, expenses, and cash flows; (ii) terminal period revenue growth and cash flows; (iii) an estimated weighted average cost of capital; (iv) an assumed discount rate depending on the asset; (v) a tax rate; and (vi) market prices for comparable assets. The Company believes these assumptions are consistent with those a hypothetical market participant would use given circumstances that were present at the time the estimates were made. However, actual results and amounts may be significantly different from the Company’s estimates.
As part of this evaluation, the Company assesses whether changes in (i) macroeconomic conditions; (ii) industry and market conditions; (iii) cost factors; (iv) overall financial performance; and (v) Company-specific events, have occurred which would impact the use and/or fair value of these assets since the Company's quantitative analysis in 2013. In 2015 and 2016, the Company performed a qualitative assessment of goodwill and determined that there was no indication that goodwill was impaired. The qualitative assessments included analyses and weighting of all relevant factors noted above. The Company performed a quantitative assessment of all indefinite-lived intangible assets in 2015 and a qualitative assessment in 2016 and determined that there was no impairment in either year. The Company did record a $21 million noncash impairment charge related to leased slots at Newark Liberty International Airport (not indefinite-lived assets) as a result of the FAA announcement in April 2016 that this airport was being changed to a Level 2 schedule-facilitated airport from its precious designation as Level 3. Southwest does not believe this FAA decision is indicative of a similar decision being made at its other slot-controlled airports.
Future impairment of Goodwill and indefinite-lived intangible assets may result from changes in assumptions, estimates, or circumstances, some of which are beyond the Company’s control. Factors which could result in an impairment of Goodwill, holding other assumptions constant, could include, but are not limited to: (i) a significant reduction in passenger demand as a result of domestic or global economic conditions; (ii) significantly higher prices for jet fuel; (iii) lower fares or passenger yields as a result of increased competition or lower demand; (iv) a significant increase in future capital expenditure commitments; and (v) significant disruptions to the Company’s operations as a result of both internal and external events such as terrorist activities, actual or threatened war, labor actions by Employees, or further industry regulation. Factors which could result in an impairment of owned domestic slots, holding other assumptions constant, could include, but are not limited to: (i) a change in competition in the slotted airport; (ii) a change in governmental regulations in the slotted airport; (iii) significantly higher prices for jet fuel; and (iv) increased competition at a nearby airport.


Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

The Company has interest rate risk in its floating-rate debt obligations and interest rate swaps, commodity price risk in jet fuel required to operate its aircraft fleet, and market risk in the derivatives used to manage its fuel hedging program and in the form of fixed-rate debt instruments. As of December 31, 2016, Southwest operated a total of 134 aircraft under operating and capital lease. However, except for a small number of aircraft that have lease payments that fluctuate based in part on changes in market interest rates, the remainder of the leases are not considered market sensitive financial instruments and, therefore, are not included in the interest rate sensitivity analysis below. The Company also has 78 aircraft under operating and capital lease that have been subleased to another carrier. Further information about this sublease arrangement is disclosed in Note 7 to the Consolidated Financial Statements. The Company does not purchase or hold any derivative financial instruments for trading purposes. See Note 10 to the Consolidated Financial Statements for information on the Company’s accounting for its hedging program and for further details on the Company’s financial derivative instruments.

Hedging

The Company purchases jet fuel at prevailing market prices, but seeks to manage market risk through execution of a documented hedging strategy. The Company utilizes financial derivative instruments, on both a short-term and a long-term basis, as a form of insurance against the potential for significant increases in fuel prices. The Company believes there can be significant risk in not hedging against the possibility of such fuel price increases, especially in energy markets in which prices are high and/or rising. The Company expects to consume approximately 2 billion gallons of jet fuel in 2017. Based on this anticipated usage, a change in jet fuel prices of just one cent per gallon would impact the Company’s Fuel and oil expense by approximately $20 million for 2017, excluding any impact associated with fuel derivative instruments held.

As of December 31, 2016, the Company held a net position of fuel derivative instruments that represented a hedge for a portion of its anticipated jet fuel purchases for each year from 2017 through 2019. See Note 10 to the Consolidated Financial Statements for further information. The Company may increase or decrease the size of its fuel hedge based on its expectation of future market prices, as well as its perceived exposure to cash collateral requirements contained in the agreements it has signed with various counterparties, while considering the significant cost that can be associated with different types of hedging strategies. The gross fair value of outstanding financial derivative instruments related to the Company’s jet fuel market price risk at December 31, 2016, was a net liability of $326 million. In addition, $301 million in cash collateral deposits were provided by the Company in connection with these instruments based on their fair value as of December 31, 2016. The fair values of the derivative instruments, depending on the type of instrument, were determined by use of present value methods or standard option value models with assumptions about commodity prices based on those observed in underlying markets. An immediate 10 percent increase or decrease in underlying fuel-related commodity prices from the December 31, 2016 (for all years from 2017 through 2019) prices would correspondingly change the fair value of the commodity derivative instruments in place by approximately $266 million. Fluctuations in the related commodity derivative instrument cash flows may change by more or less than this amount based upon further fluctuations in futures prices, as well as related income tax effects. In addition, this does not consider changes in cash, aircraft, or letters of credit utilized as collateral provided to or by counterparties, which would fluctuate in an amount equal to or less than this amount, depending on the type of collateral arrangement in place with each counterparty. This sensitivity analysis uses industry standard valuation models and holds all inputs constant at December 31, 2016, levels, except underlying futures prices.

The Company’s credit exposure related to fuel derivative instruments is represented by the fair value of contracts that are an asset to the Company. At such times, these outstanding instruments expose the Company to credit loss in the event of nonperformance by the counterparties to the agreements. As of December 31, 2016, the Company had five counterparties in which the derivatives held were a net asset. To manage credit risk, the Company selects and periodically reviews counterparties based on credit ratings, limits its exposure with respect to each counterparty, and monitors the market position of the fuel hedging program and its relative market position with each counterparty. However, if one or more of these counterparties were in a liability position to the Company and were unable to meet their obligations,
any open derivative contracts with the counterparty could be subject to early termination, which could result in substantial losses for the Company. At December 31, 2016, the Company had agreements with all of its active counterparties containing early termination rights and/or bilateral collateral provisions whereby security is required if market risk exposure exceeds a specified threshold amount based on the counterparty’s credit rating. The Company also had agreements with counterparties in which cash deposits, letters of credit, and/or pledged aircraft are required to be posted as collateral whenever the net fair value of derivatives associated with those counterparties exceeds specific thresholds. Refer to the counterparty credit risk and collateral table provided in Note 10 to the Consolidated Financial Statements for the fair values of fuel derivatives, amounts posted as collateral, and applicable collateral posting threshold amounts as of December 31, 2016, at which such postings are triggered.

Due to the terms of the Company’s current fuel hedging agreements with counterparties and the types of derivatives held, in the Company’s judgment, it does not have significant additional cash collateral exposure. Given its investment grade credit rating, the Company can meet any additional significant collateral calls by posting aircraft and/or letters of credit. As an example, if market prices for the commodities used in the Company’s fuel hedging activities were to decrease by 25 percent from market prices as of December 31, 2016, given the Company’s current fuel derivative portfolio, its aircraft collateral facilities, and its investment grade credit rating, it would likely provide an additional $256 million in collateral. The Company would have the option of providing cash, letters of credit, and/or pledging aircraft in order to meet this collateral requirement. At December 31, 2016, the Company had $1.6 billion in aircraft available to be posted as collateral. In addition, the Company would expect to also benefit from lower market prices paid for fuel used in its operations. See Note 10 to the Consolidated Financial Statements.

The Company is also subject to the risk that the fuel derivatives it uses to hedge against fuel price volatility do not provide adequate protection. In recent years, jet fuel prices have been closely correlated with changes in the price of Brent crude oil. The Company has attempted to mitigate some of this risk by entering into more fuel hedges based on Brent crude oil. In addition, to add further protection, the Company may periodically enter into jet fuel derivatives for short-term timeframes. Jet fuel is not widely traded on an organized futures exchange and, therefore, there are limited opportunities to hedge directly in jet fuel for time horizons longer than approximately 24 months into the future.
 
The Company also has agreements with each of its counterparties associated with its outstanding interest rate swap agreements in which cash collateral may be required based on the fair value of outstanding derivative instruments, as well as the Company’s and its counterparty’s credit ratings. As of December 31, 2016, no cash collateral deposits were provided by or held by the Company based on its outstanding interest rate swap agreements.

Due to the significance of the Company’s fuel hedging program and the emphasis that the Company places on utilizing fuel derivatives to reduce its fuel price risk, the Company has created a system of governance and management oversight and has put in place a number of internal controls designed so that procedures are properly followed and accountability is present at the appropriate levels. For example, the Company has put in place controls designed to: (i) create and maintain a comprehensive risk management policy; (ii) provide for proper authorization by the appropriate levels of management; (iii) provide for proper segregation of duties; (iv) maintain an appropriate level of knowledge regarding the execution of and the accounting for derivative instruments; and (v) have key performance indicators in place in order to adequately measure the performance of its hedging activities. The Company believes the governance structure that it has in place is adequate given the size and sophistication of its hedging program.

Financial Market Risk

The vast majority of the Company’s tangible assets are aircraft, which are long-lived. The Company’s strategy is to maintain a conservative balance sheet and grow capacity steadily and profitably under the right conditions. While the Company uses financial leverage, it strives to maintain a strong balance sheet and has a “BBB+” rating with Fitch, a “BBB” rating with Standard & Poor’s, and a “Baa1” credit rating with Moody’s as of December 31, 2016, all of which are considered “investment grade.” The Company’s French Credit Agreements due 2018 do not give rise to significant fair value risk but do give rise to interest rate risk because this borrowing was originally issued as floating-rate debt. In addition, as disclosed in Note 10 to the Consolidated Financial Statements, the Company has converted certain of its long-term debt to floating rate debt by entering into an interest rate swap agreement. Although there is interest rate

60


risk associated with these floating rate borrowings, the risk of the French Credit Agreements due 2018 is somewhat mitigated by the fact that the Company may prepay this debt under certain conditions. See Note 6 to the Consolidated Financial Statements for more information on the material terms of the Company’s short-term and long-term debt.

As of December 31, 2016, excluding the notes or debentures that have been converted to a floating rate, the Company’s fixed-rate senior unsecured notes outstanding included its $300 million 5.125% senior unsecured notes due 2017, its $300 million 3.00% senior unsecured notes due 2026, and its $100 million 7.375% senior unsecured notes due 2027. Excluding the notes due 2026, these notes had at one point been converted to floating rates, but the Company subsequently terminated the fixed-to-floating interest rate swap agreements related to them. The effect of these terminations was that the interest associated with these debts prospectively reverted back to their original fixed rates. As a result of the gains realized on these transactions, which are being amortized over the remaining term of the corresponding notes, and based on projected interest rates at the date of termination, the Company does not believe its future interest expense, based on projected future interest rates at the date of termination, associated with these notes will significantly differ from the expense it would have recorded had the notes remained at floating rates. The following table displays the characteristics of the Company’s secured fixed rate debt as of December 31, 2016:

The carrying value of the Company’s floating rate debt totaled $1.1 billion, and this debt had a weighted-average maturity of 4.69 years at floating rates averaging 1.97 percent for the year ended December 31, 2016. In total, the Company’s fixed-rate debt and floating rate debt represented 12.44 percent and 5.59 percent, respectively, of consolidated noncurrent assets at December 31, 2016.

The Company also has some risk associated with changing interest rates due to the short-term nature of its invested cash, which totaled $1.7 billion, and short-term investments, which totaled $1.6 billion at December 31, 2016. See Notes 1 and 11 to the Consolidated Financial Statements for further information. The Company currently invests available cash in certificates of deposit, highly rated money market instruments, investment grade commercial paper, treasury securities, U.S. government agency securities, and other highly rated financial instruments, depending on market conditions and operating cash requirements. Because of the short-term nature of these investments, the returns earned parallel closely with short-term floating interest rates. The Company has not undertaken any additional actions to cover interest rate market risk and is not a party to any other material market interest rate risk management activities.

A hypothetical 10 percent change in market interest rates as of December 31, 2016, would not have a material effect on the fair value of the Company’s fixed-rate debt instruments. See Note 11 to the Consolidated Financial Statements for further information on the fair value of financial instruments. A change in market interest rates could, however, have a corresponding effect on earnings and cash flows associated with the Company’s floating-rate debt, invested cash (excluding cash collateral deposits held, if applicable), floating-rate aircraft leases, and short-term investments because of the floating-rate nature of these items. Assuming floating market rates in effect as of December 31, 2016 were held constant throughout a 12-month period, a hypothetical 10 percent change in those rates would have an immaterial impact on the Company’s net earnings and cash flows. Utilizing these assumptions and considering the Company’s cash balance (excluding the impact of cash collateral deposits held or provided to counterparties, if applicable), short-term investments, and floating-rate debt outstanding at December 31, 2016, an increase in rates would have a net negative effect on the Company’s earnings and cash flows, while a decrease in rates would have a net positive effect on the Company’s earnings and cash flows. However, a 10 percent change in market rates would not impact the Company’s earnings or cash flow associated with the Company’s publicly traded fixed-rate debt.

The Company is also subject to a financial covenant included in its revolving credit facility, and is subject to credit rating triggers related to its credit card transaction processing agreements, the pricing related to any funds drawn under

61


its revolving credit facility, and some of its hedging counterparty agreements. Certain covenants include the maintenance of minimum credit ratings and/or triggers that are based on changes in these ratings. The Company’s revolving credit facility contains a financial covenant requiring a minimum coverage ratio of adjusted pre-tax income to fixed obligations, as defined. As of December 31, 2016, the Company was in compliance with this covenant and there were no amounts outstanding under the revolving credit facility. However, if conditions change and the Company fails to meet the minimum standards set forth in the revolving credit facility, there could be a reduction in the availability of cash under the facility, or an increase in the costs to keep the facility intact as written. The Company’s hedging counterparty agreements contain ratings triggers in which additional cash collateral could be required to be posted with the counterparty if the Company’s credit rating were to fall below investment grade by two of the three major rating agencies, and if the Company were in a net liability position with the counterparty. See Note 10 to the Consolidated Financial Statements for further information. As of December 31, 2016, $301 million in cash collateral deposits were provided by the Company under these provisions. If the Company’s credit rating had been below investment grade as of that date, the Company would not have been required to post additional cash collateral deposits with fuel hedge counterparties because it had room available under its existing aircraft collateral facilities.

The Company currently has agreements with organizations that process credit card transactions arising from purchases of air travel tickets by its Customers utilizing American Express, Discover, and MasterCard/VISA. Credit card processors have financial risk associated with tickets purchased for travel because the processor generally forwards the cash related to the purchase to the Company soon after the purchase is completed, but the air travel generally occurs after that time; therefore, the processor will have liability if the Company does not ultimately provide the air travel. Under these processing agreements, and based on specified conditions, increasing amounts of cash reserves could be required to be posted with the counterparty.

A majority of the Company’s sales transactions are processed by Chase Paymentech. Should chargebacks processed by Chase Paymentech reach a certain level, proceeds from advance ticket sales could be held back and used to establish a reserve account to cover such chargebacks and any other disputed charges that might occur. Additionally, cash reserves are required to be established if the Company’s credit rating falls to specified levels below investment grade. Cash reserve requirements are based on the Company’s public debt rating and a corresponding percentage of the Company’s Air traffic liability.

As of December 31, 2016, the Company was in compliance with all credit card processing agreements. However, the inability to enter into credit card processing agreements would have a material adverse effect on the business of the Company. The Company believes that it will be able to continue to renew its existing credit card processing agreements or will be able to enter into new credit card processing agreements with other processors in the future.

Southwest Airlines Co.
Notes to Consolidated Financial Statements

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

Southwest Airlines Co. (the “Company”) operates Southwest Airlines, a major domestic airline. The Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries, which include AirTran Holdings, LLC. The Company owns all of the outstanding equity of AirTran Holdings, Inc. (“AirTran Holdings”), the former parent company of AirTran Airways, Inc. (“AirTran Airways”). Throughout these Notes, the Company makes reference to AirTran, which is meant to be inclusive of AirTran Holdings, LLC, the successor to AirTran Holdings, and its subsidiaries, including among others, AirTran Airways. AirTran's final passenger service was on December 28, 2014. All integration costs were incurred in periods prior to 2016. The accompanying Consolidated Financial Statements include the results of operations and cash flows for all periods presented and all significant inter-entity balances and transactions have been eliminated. The preparation of financial statements in conformity with generally accepted accounting principles in the United States (GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates.

Cash and Cash Equivalents

Cash in excess of that necessary for operating requirements is invested in short-term, highly liquid, income-producing investments. Investments with original maturities of three months or less when purchased are classified as cash and cash equivalents, which primarily consist of certificates of deposit, money market funds, and investment grade commercial paper issued by major corporations and financial institutions. Cash and cash equivalents are stated at cost, which approximates fair value.

As of December 31, 2016, $301 million in net cash collateral deposits were provided by the Company to its fuel hedge counterparties and no cash collateral deposits were held by or provided by the Company to its interest rate hedge counterparties. As of December 31, 2015, $835 million in cash collateral deposits were provided by the Company to its fuel hedge counterparties and no cash collateral deposits were held by or provided by the Company to its interest rate hedge counterparties. Cash collateral amounts provided or held associated with fuel and interest rate derivative instruments are not restricted in any way and earn interest income at an agreed upon rate that approximates the rates earned on short-term securities issued by the U.S. Government. Depending on the fair value of the Company’s fuel and interest rate derivative instruments, the amounts of collateral deposits held or provided at any point in time can fluctuate significantly. See Note 10 for further information on these collateral deposits and fuel derivative instruments.

Short-term and Noncurrent Investments

Short-term investments consist of investments with original maturities of greater than three months but less than twelve months when purchased. These are primarily short-term securities issued by the U.S. Government and certificates of deposit issued by domestic banks. All of these investments are classified as available-for-sale securities and are stated at fair value, which approximates cost. For all short-term investments, at each reset period or upon reinvestment, the Company accounts for the transaction as Proceeds from sales of short-term investments for the security relinquished, and Purchases of short-investments for the security purchased, in the accompanying Consolidated Statement of Cash Flows. Unrealized gains and losses, net of tax, if any, are recognized in Accumulated other comprehensive income (loss) (“AOCI”) in the accompanying Consolidated Balance Sheet. Realized net gains and losses on specific investments, if any, are reflected in Interest income in the accompanying Consolidated Statement of Income. Both unrealized and realized gains and/or losses associated with investments were immaterial for all years presented.

Noncurrent investments consist of investments with maturities of greater than twelve months. Noncurrent investments are included as a component of Other assets in the Consolidated Balance Sheet.

68



Accounts and Other Receivables

Accounts and other receivables are carried at cost. They primarily consist of amounts due from credit card companies associated with sales of tickets for future travel, and amounts due from business partners in the Company’s frequent flyer program. The allowance for doubtful accounts was immaterial at December 31, 2016 and 2015. In addition, the provision for doubtful accounts and write-offs for 2016, 2015, and 2014 were each immaterial.

Inventories

Inventories primarily consist of aircraft fuel, flight equipment expendable parts, materials, and supplies. All of these items are carried at average cost, less an allowance for obsolescence. These items are generally charged to expense when issued for use. The reserve for obsolescence was $57 million and $47 million at December 31, 2016, and 2015, respectively. In addition, the Company’s provision for obsolescence and write-offs for 2016, 2015, and 2014 were each immaterial.

Property and Equipment

Property and equipment is stated at cost. Capital expenditures includes payments made for aircraft, other flight equipment, purchase deposits related to future aircraft deliveries, and ground and other property and equipment. Depreciation is provided by the straight-line method to estimated residual values over periods generally ranging from 23 to 25 years for flight equipment, 5 to 30 years for ground property and equipment, and 25 to 30 years, or the expected term of the Company's lease if shorter, for Assets constructed for others, once the asset is placed in service. Residual values estimated for aircraft generally range from 2 to 20 percent, for ground property and equipment generally range from 0 to 10 percent, and for Assets constructed for others range from 17 to 25 percent. Property under capital leases and related obligations are initially recorded at an amount equal to the present value of future minimum lease payments computed on the basis of the Company’s incremental borrowing rate or, when known, the interest rate implicit in the lease. Amortization of property under capital leases is on a straight-line basis over the lease term and is included in Depreciation and amortization expense. Leasehold improvements generally are amortized on a straight-line basis over the shorter of the estimated useful life of the improvement or the remaining term of the lease. Assets constructed for others primarily consists of airport improvement projects, once placed into service, in which the Company is considered the accounting owner of the facilities. See Note 4 for further information.

During first quarter 2016, the Company made the decision to further simplify its operations and accelerate the retirement of its less-efficient Classic fleet to no later than third quarter 2017, versus the original scheduled retirement of this fleet that had extended out to 2021. This change in retirement dates is considered a change in estimate and has been accounted for on a prospective basis as of the dates the decisions were finalized. Therefore, the Company has recorded and will record accelerated depreciation expense over the remainder of the useful lives for each Classic aircraft and related parts. See Note 7 for further information regarding the Company's aircraft fleet.


The impacts on expense and earnings from this change in assumption for the year ended December 31, 2016 are as follows:

The estimated impact to Depreciation and amortization expense from this change in assumption for 2017 is an approximate increase of $21 million.

The Company evaluates its long-lived assets used in operations for impairment when events and circumstances indicate that the undiscounted cash flows to be generated by that asset are less than the carrying amounts of the asset and may not be recoverable. Factors that would indicate potential impairment include, but are not limited to, significant decreases in the market value of the long-lived asset(s), a significant change in the long-lived asset’s physical condition, and operating or cash flow losses associated with the use of the long-lived asset. If an asset is deemed to be impaired, an impairment loss is recorded for the excess of the asset book value in relation to its estimated fair value.

Aircraft and Engine Maintenance

The cost of scheduled inspections and repairs and routine maintenance costs for all aircraft and engines are charged to Maintenance materials and repairs expense as incurred. The Company also has “power-by-the-hour” agreements related to certain of its aircraft engines with external service providers. Under these agreements, which the Company has determined effectively transfer the risk and create an obligation associated with the maintenance on such engines to the counterparty, expense is recorded commensurate with each hour flown on an engine. In situations where the payments to the counterparty do not sufficiently match the level of services received during the period, expense is recorded on a straight-line basis over the term of the agreement based on the Company's best estimate of expected future aircraft utilization. For its engine maintenance contracts that do not transfer risk to the service provider, the Company records expense on a time and materials basis when an engine repair event takes place. Modifications that significantly enhance the operating performance or extend the useful lives of aircraft or engines are capitalized and amortized over the remaining life of the asset.

Goodwill and Intangible Assets

The Company applies a fair value based impairment test to the carrying value of goodwill and indefinite-lived intangible assets annually on October 1st, or more frequently if certain events or circumstances indicate that an impairment loss may have been incurred. The Company assesses the value of goodwill and indefinite-lived assets under either a qualitative or quantitative approach. Under a qualitative approach, the Company considers various market factors, including applicable key assumptions listed below. These factors are analyzed to determine if events and circumstances could reasonably have affected the fair value of goodwill and indefinite-lived intangible assets. If the Company determines that it is more likely than not that an indefinite-lived intangible asset is impaired, the quantitative approach is used to assess the asset’s implied fair value and the amount of the impairment. Under a quantitative approach, the implied fair value of the Company's identifiable assets and liabilities is calculated based on key assumptions. If the Company assets' carrying value exceeds the fair value calculated using the quantitative approach, an impairment charge is recorded for the difference in fair value and carrying value.

The following table is a summary of the Company’s intangible assets, which are included as a component of Other assets in the Company's Consolidated Balance Sheet, as of December 31, 2016 and 2015:

(a) The Company recorded a $21 million impairment associated with owned and leased slots at Newark Liberty International Airport as a result of the FAA announcement, in April 2016, that this airport was being changed to a Level 2 schedule-facilitated airport from its previous designation as Level 3.
(b) Intangible assets primarily consist of acquired leasehold rights to certain airport owned gates, takeoff and landing slots (a “slot” is the right of an air carrier, pursuant to regulations of the FAA, to operate a takeoff or landing at a specific time at certain airports) at certain domestic slot-controlled airports, and certain intangible assets acquired.

The aggregate amortization expense for 2016, 2015, and 2014 was $17 million, $19 million, and $13 million, respectively. Estimated aggregate amortization expense for the five succeeding years and thereafter is as follows: 2017 – $13 million, 2018 – $13 million, 2019 – $13 million, 2020 – $12 million, 2021 – $12 million, and thereafter – $68 million.

Revenue Recognition

Tickets sold are initially deferred as Air traffic liability. Passenger revenue is recognized when transportation is provided. Air traffic liability primarily represents tickets sold for future travel dates and funds that are past flight date and remain unused. The majority of the Company’s tickets sold are nonrefundable. Refundable tickets that are sold but not flown on the travel date can be reused for another flight, up to a year from the date of sale, or refunded. A small percentage of tickets (or partial tickets) expire unused. The Company estimates the amount of tickets that expire unused and recognizes such amounts in Passenger revenue using the redemption method based on the scheduled flight date. Southwest has a No Show policy that applies to certain nonrefundable fares that are not canceled or changed by a Customer at least ten minutes prior to a flight's scheduled departure. Based on the Company's revenue recognition policy, revenue is recorded at the flight date for a Customer who does not change his/her itinerary and loses his/her funds. Amounts collected from passengers for ancillary service fees are generally recognized as Other revenue when the service is provided, which is typically the flight date.

The Company's policy is to record revenue for the estimated spoilage of tickets (including partial tickets) once the flight date has passed, under the redemption method. Initial spoilage estimates are routinely adjusted and ultimately finalized once the tickets expire, which is typically twelve months after the original purchase date. Spoilage estimates are based on the Customers' historical travel behavior as well as assumptions about the Customers' future travel behavior. Assumptions used to generate spoilage estimates can be impacted by several factors including, but not limited to: fare increases, fare sales, changes to the Company's ticketing policies, changes to the Company’s refund, exchange and unused funds policies, and economic factors.

The Company is also required to collect certain taxes and fees from Customers on behalf of government agencies and remit these back to the applicable governmental entity on a periodic basis. These taxes and fees include foreign and U.S. federal transportation taxes, federal security charges, and airport passenger facility charges. These items are collected from Customers at the time they purchase their tickets, but are not included in Passenger revenue. The Company records a liability upon collection from the Customer and relieves the liability when payments are remitted to the applicable governmental agency.

71



Frequent Flyer Program

The Company records a liability for the estimated incremental cost of providing free travel under its frequent flyer program for all amounts earned from flight activity that are expected to be redeemed for future travel. The estimated incremental cost includes direct passenger costs such as fuel, food, and other operational costs, but does not include any contribution to fixed overhead costs or profit.

Southwest also sells frequent flyer points and related services to companies participating in its frequent flyer program. Historically, until July 1, 2015, funds received from the sale of points associated with these agreements were accounted for under the residual method. Under this method, the Company estimated the portion of the amounts received from the sale of frequent flyer points that related to free travel and these amounts were deferred and recognized as Passenger revenue when the ultimate free travel awards were flown. Effective July 1, 2015, the Company entered into an amended co-branded credit card agreement ("Agreement") with Chase Bank USA, N.A. (“Chase”), through which the Company sells loyalty points and other items to Chase. This material modification triggered an accounting change under ASU 2009-13, which was recorded on a prospective basis. The impact of the accounting change is that the Company estimated the selling prices and volumes over the term of the Agreement in order to determine the allocation of proceeds to each of the deliverables (travel points to be awarded; use of the Southwest Airlines’ brand and access to Rapid Reward Member lists; advertising elements; and the Company’s resource team). The Company records passenger revenue related to air transportation and certificates for discounted companion travel when the transportation is delivered. The other elements are recognized as Other - net revenue when earned.

The Company followed the transition approach of ASU 2009-13, which required that the Company adjust the existing deferred revenue balance, classified within Air traffic liability, to reflect the value, on a relative selling price basis, of any undelivered element remaining at the date of contract modification. The relative selling price of the undelivered element (air transportation) was lower than the rate at which it had been deferred under the residual method, and the Company recorded a one-time, non-cash adjustment to decrease frequent flyer deferred revenue and increase revenue through the recording of a Special revenue adjustment of $172 million in 2015. The estimated impacts on revenue and earnings associated with the Agreement and this change in accounting principle recognized subsequent to the effective date of July 1, 2015, are as follows:

For all points sold to business partners that are expected to expire unused, the Company recognizes spoilage in accordance with the redemption method. The Company’s consolidated liability associated with the sale of frequent flyer points, was approximately $1.4 billion and $1.3 billion as of December 31, 2016, and 2015, respectively, which is classified within Air traffic liability. During fourth quarter 2014, the Company obtained sufficient historical behavioral data to develop a predictive statistical model to analyze the amount of spoilage expected for points sold to business partners, which indicated an increase in the expected spoilage rate. This change in estimate was recorded on a prospective basis, as of October 1, 2014. The impacts on revenue and earnings were as follows:

The Company continues to evaluate annually in October, but these analyses have not resulted in a material adjustment.

Advertising

Advertising costs are charged to expense as incurred. Advertising and promotions expense for the years ended December 31, 2016, 2015, and 2014 was $232 million, $218 million, and $207 million, respectively, and is included as a component of Other operating expense in the accompanying Consolidated Statement of Income.

Share-based Employee Compensation

The Company has share-based compensation plans covering certain Employees, including a plan that also covers the Company’s Board of Directors. The Company accounts for share-based compensation based on its grant date fair value. See Note 9 for further information.

Financial Derivative Instruments

The Company accounts for financial derivative instruments at fair value and applies hedge accounting rules where appropriate. The Company utilizes various derivative instruments, including jet fuel, crude oil, unleaded gasoline, and heating oil-based derivatives, to attempt to reduce the risk of its exposure to jet fuel price increases. These instruments consist primarily of purchased call options, collar structures, call spreads, put spreads, and fixed price swap agreements, and upon proper qualification are accounted for as cash-flow hedges. The Company also has interest rate swap agreements to convert a portion of its fixed-rate debt to floating rates and has swap agreements that convert certain floating-rate debt to a fixed-rate. These interest rate hedges are appropriately designated as either fair value hedges or as cash flow hedges.

Since the majority of the Company’s financial derivative instruments are not traded on a market exchange, the Company estimates their fair values. Depending on the type of instrument, the values are determined by the use of present value methods or option value models with assumptions about commodity prices based on those observed in underlying markets. Also, since there is not a reliable forward market for jet fuel, the Company must estimate the future prices of jet fuel in order to measure the effectiveness of the hedging instruments in offsetting changes to those prices. Forward jet fuel prices are estimated through utilization of a statistical-based regression equation with data from market forward prices of like commodities. This equation is then adjusted for certain items, such as transportation costs, that are stated in the Company’s fuel purchasing contracts with its vendors.

For the effective portion of settled fuel hedges, the Company records the associated gains or losses as a component of Fuel and oil expense in the Consolidated Statement of Income. For amounts representing ineffectiveness, as defined, or changes in fair value of derivative instruments for which hedge accounting is not applied, the Company records any gains or losses as a component of Other (gains) losses, net, in the Consolidated Statement of Income. Amounts that are paid or received in connection with the purchase or sale of financial derivative instruments (i.e., premium costs of option contracts) are classified as a component of Other (gains) losses, net, in the Consolidated Statement of Income in the period in which the instrument settles or expires. All cash flows associated with purchasing and selling derivatives are classified as operating cash flows in the Consolidated Statement of Cash Flows, within Changes in certain assets and liabilities. See Note 10 for further information on hedge accounting and financial derivative instruments.


73


The Company classifies its cash collateral provided to or held from counterparties in a “net” presentation on the Consolidated Balance Sheet against the fair value of the derivative positions with those counterparties. See Note 10 for further information.

Software Capitalization

The Company capitalizes certain internal and external costs related to the acquisition and development of internal use software during the application development stages of projects. The Company amortizes these costs using the straight-line method over the estimated useful life of the software, which is typically five to fifteen years. Costs incurred during the preliminary project or the post-implementation/operation stages of the project are expensed as incurred. Capitalized computer software, included as a component of Ground property and equipment in the accompanying Consolidated Balance Sheet, net of accumulated depreciation, was $544 million and $378 million at December 31, 2016, and 2015, respectively. Computer software depreciation expense was $111 million, $106 million, and $122 million for the years ended December 31, 2016, 2015, and 2014, respectively, and is included as a component of Depreciation and amortization expense in the accompanying Consolidated Statement of Income. The Company evaluates internal use software for impairment on a quarterly basis; if it is determined the value of an asset was not recoverable or it qualifies for impairment, a charge would be recorded to write down the software to the lower of its carrying value or fair value. The Company had no significant impairments during 2016, 2015, or 2014.

Income Taxes

The Company accounts for deferred income taxes utilizing an asset and liability method, whereby deferred tax assets and liabilities are recognized based on the tax effect of temporary differences between the financial statements and the tax basis of assets and liabilities, as measured by current enacted tax rates. The Company also evaluates the need for a valuation allowance to reduce deferred tax assets to estimated recoverable amounts. See "Basis of Presentation" for further information on current presentation of deferred income taxes.

The Company’s policy for recording interest and penalties associated with uncertain tax positions is to record such items as a component of income before income taxes. Penalties are recorded in Other (gains) losses, net, and interest paid or received is recorded in Interest expense or Interest income, respectively, in the Consolidated Statement of Income. Amounts recorded for penalties and interest related to uncertain tax positions were immaterial for all years presented. See Note 14 for further information.

Concentration Risk

Approximately 83 percent of the Company’s full-time equivalent Employees are unionized and are covered by collective-bargaining agreements. A small percentage of the Company's unionized Employees, including its Mechanics, Material Specialists, and Facilities Maintenance Technicians, are in discussions on labor agreements. These Employee groups represent approximately five percent of the Company’s full-time equivalent Employees as of December 31, 2016.

The Company attempts to minimize its concentration risk with regards to its cash, cash equivalents, and its investment portfolio. This is accomplished by diversifying and limiting amounts among different counterparties, the type of investment, and the amount invested in any individual security or money market fund.

To manage risk associated with financial derivative instruments held, the Company selects and will periodically review counterparties based on credit ratings, limits its exposure to a single counterparty, and monitors the market position of the program and its relative market position with each counterparty. The Company also has agreements with counterparties containing early termination rights and/or bilateral collateral provisions whereby security is required if market risk exposure exceeds a specified threshold amount or credit ratings fall below certain levels. Collateral deposits provided to or held from counterparties serve to decrease, but not totally eliminate, the credit risk associated with the Company’s hedging program. See Note 10 for further information.

74



As of December 31, 2016, the Company operated an all-Boeing fleet, all of which are variations of the Boeing 737. If the Company were unable to acquire additional aircraft or associated aircraft parts from Boeing, or Boeing were unable or unwilling to make timely deliveries of aircraft or to provide adequate support for its products, the Company’s operations would be materially adversely impacted. In addition, the Company would be materially adversely impacted in the event of a mechanical or regulatory issue associated with the Boeing 737 aircraft type, whether as a result of downtime for part or all of the Company’s fleet, increased maintenance costs, or because of a negative perception by the flying public. The Company is also dependent on sole suppliers for aircraft engines and certain other aircraft parts and would, therefore, also be materially adversely impacted in the event of the unavailability of, or a mechanical or regulatory issue associated with, engines and other parts.

The Company has historically entered into agreements with some of its co-brand, payment, and loyalty partners that contain exclusivity aspects which place certain confidential restrictions on the Company from entering into certain arrangements with other payment and loyalty partners. These arrangements generally extend for the terms of the agreements, none of which currently extend beyond May 2022. The Company believes the financial benefits generated by the exclusivity aspects of these arrangements outweigh the risks involved with such agreements.

2. NEW ACCOUNTING PRONOUNCEMENTS AND ACCOUNTING CHANGES
    
On August 26, 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-15, Statement of Cash Flows. The standard is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. The Company is evaluating the new guidance, but does not expect it to have a significant impact on its financial statement presentation or results.

On June 16, 2016, the FASB issued ASU No. 2016-13, Accounting for Credit Losses. The new standard requires the use of an “expected loss” model on certain types of financial instruments. The standard also amends the impairment model for available-for-sale debt securities and requires estimated credit losses to be recorded as allowances instead of reductions to amortized cost of the securities. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019, with early adoption permitted. The Company is evaluating the new guidance, but does not expect it to have a significant impact on its financial statement presentation or results.

On March 30, 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting. The standard is part of the FASB effort to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption is permitted in any interim or annual period, with any adjustments reflected as of the beginning of the fiscal year of adoption. The Company early adopted this standard during the three months ended June 30, 2016, with an effective date as of January 1, 2016. The prospective method of adoption of this standard resulted in the recognition of $7 million of excess tax benefits to the Company's income tax provision for the year ended December 31, 2016.

On February 25, 2016, the FASB issued ASU No. 2016-02, Leases. The standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. The Company believes the most significant impact of this ASU on its accounting will be the presentation of operating leases with durations greater than twelve months, with certain exceptions, on the balance sheet. A portion of the Company's aircraft fleet is on operating lease, and it has contractual lease agreements associated with the majority of space from which it operates at the airports it serves. See Note 7 for more information on the Company's lease arrangements. The Company has formed a project team to evaluate and implement the standard and plans to provide additional information about its expected financial impact at a future date.

On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. Following the FASB's finalization of a one year deferral of this standard, the ASU is now effective for fiscal years, and interim periods within

75

those years, beginning on or after December 15, 2017, with early adoption permitted for fiscal years, and interim periods within those years, beginning on or after December 15, 2016. The Company has formed a project team to evaluate and implement the standard, and currently believes the most significant impact of this ASU on its accounting will be the elimination of the incremental cost method for frequent flyer accounting, which will require the Company to re-value its liabilities associated with Customer flight points with a relative fair value approach, resulting in a significant increase in the liabilities. The Company's liabilities associated with these flight points was $63 million at December 31, 2016, and the Company currently estimates that applying a relative fair value would increase the liabilities by approximately twenty times that value. The adoption of the new standard is also expected to result in different income statement classification for certain types of revenues, such as ancillary revenues, which are currently classified as Other revenues. The Company currently anticipates utilizing the full retrospective method of adoption allowed by the standard, in order to provide for comparative results in all periods presented, and plans to adopt the standard as of January 1, 2018. The Company is continuing to evaluate the new guidance both internally and through its participation in an industry working group, and plans to provide additional information at a future date.

Commitments

The Company has contractual obligations and commitments primarily with regard to future purchases of aircraft, repayment of debt (see Note 6), and lease arrangements (see Note 7). During the year ended December 31, 2016, the Company purchased 38 new 737-800 aircraft from Boeing and acquired 23 used 737-700 aircraft from third parties under capital leases. In addition, the Company retired from service 42 of its older aircraft (31 737-300 and 11 737-500). As of December 31, 2016, the Company had firm deliveries and options for Boeing 737-700, 737-800, 737-7, and 737-8 aircraft as follows:

The Company's capital commitments associated with the firm orders and additional aircraft in the above aircraft table are as follows: $1.1 billion in 2017, $893 million in 2018, $614 million in 2019, $821 million in 2020, $952 million in 2021, and $5.1 billion thereafter.

Fort Lauderdale-Hollywood International Airport
In December 2013, the Company entered into an agreement with Broward County, Florida, which owns and operates Fort Lauderdale-Hollywood International Airport, to oversee and manage the design and construction of the airport's Terminal 1 Modernization Project. Pursuant to an addendum entered into during 2016, the cost of the project is not to exceed $333 million. In addition to significant improvements to the existing Terminal 1, the project includes the design and construction of a new five-gate Concourse A with an international processing facility. Funding for the project has come directly from Broward County aviation sources, but flows through the Company in its capacity as manager of the project. Major construction on the project began during third quarter 2015 and is estimated to be substantially completed by mid-2017. The Company has determined that due to its agreed upon role in overseeing and managing the project, it is considered the owner of the project for accounting purposes. As such, during construction the Company records expenditures as Assets constructed for others in the Consolidated Balance Sheet, along with a corresponding outflow within Assets constructed for others in the Consolidated Statement of Cash Flows, and an increase to Construction obligation (with a corresponding cash inflow from Financing activities in the Consolidated Statement of Cash Flows) as reimbursements are received from Broward County. As of December 31, 2016, the Company had recorded construction costs related to the project of $132 million.

Houston William P. Hobby Airport
The Company entered into a Memorandum of Agreement (“MOA”) with the City of Houston (“City”), effective June 2012, to expand the existing Houston Hobby airport facility. As provided in the MOA, the Company and the City entered into an Airport Use and Lease Agreement (“Lease”) to control the execution of this expansion and the financial terms thereof. Per the MOA and Lease, this project provided a new five-gate international terminal with international passenger processing facilities, expansion of the security checkpoint, and upgrades to the Southwest Airlines ticket counter area. Construction was effectively completed in October 2015, at which time the Company began operating from the new facility. The project's final cost was approximately $150 million, of which $22 million was considered proprietary and thus not classified as Assets constructed for others. The Company provided the funding for, as well as

77

management over, the project. In return, the capital cost portion of the rent the Company pays for the international facility is waived from the initial occupancy until the expiration of the Lease. However, the City has the option at any time during the term of the Lease to reimburse the Company's investment at the then-unamortized cost of the facility. This purchase would trigger payment of the previously waived capital cost component of rents owed the City. Additionally, a small portion of the project qualified for rental credits that have been utilized against a portion of the Company’s 2016 lease payments at the airport.

As a result of its significant involvement in the Houston Hobby project, the Company determined that it is the owner of the facility for accounting purposes. As such, during construction, the Company recorded expenditures as Assets constructed for others in the Consolidated Balance Sheet, along with a corresponding outflow within Assets constructed for others, in the Consolidated Statement of Cash Flows.

Los Angeles International Airport
In March 2013, the Company executed a lease agreement with Los Angeles World Airports (“LAWA”), which owns and operates Los Angeles International Airport ("LAX"). Under the lease agreement, which was amended in June 2014, the Company is overseeing and managing the design, development, financing, construction, and commissioning of the airport's Terminal 1 Modernization Project (the “Project”) at a cost not to exceed $526 million. The Project is being funded primarily using the Regional Airports Improvement Corporation ("RAIC"), which is a quasi-governmental special purpose entity that acts as a conduit borrower under a syndicated credit facility provided by a group of lenders. Loans made under the credit facility are being used to fund the development of the Project, and the outstanding loans will be repaid with the proceeds of LAWA’s payments to purchase completed Project phases. The Company has guaranteed the obligations of the RAIC under the credit facility. Construction on the Project began during 2014 and is estimated to be completed during 2018. The Company has determined that due to its agreed upon role in overseeing and managing the Project, it is considered the owner of the Project for accounting purposes. LAWA will reimburse the Company (through the RAIC credit facility) for the non-proprietary renovations, while proprietary renovations will not be reimbursed. As a result, the $344 million of costs incurred as of December 31, 2016, to fund the Project are included within Assets constructed for others and all amounts that have been or will be reimbursed will be included within Construction obligation on the accompanying Consolidated Balance Sheet.

Dallas Love Field

During 2008, the City of Dallas approved the Love Field Modernization Program (“LFMP”), a project to reconstruct Dallas Love Field with modern, convenient air travel facilities. Pursuant to a Program Development Agreement with the City of Dallas and the Love Field Airport Modernization Corporation (or “LFAMC,” a Texas non-profit “local government corporation” established by the City of Dallas to act on the City of Dallas' behalf to facilitate the development of the LFMP), the Company managed this project. Major construction was effectively completed by December 31, 2014. This project consisted of the complete replacement of gate facilities with a new 20-gate facility, including infrastructure, systems and equipment, aircraft parking apron, fueling system, roadways and terminal curbside, baggage handling systems, passenger loading bridges and support systems, and other supporting infrastructure.

Although the City of Dallas received commitments from various sources that are helping to fund portions of the LFMP project, including the FAA, the Transportation Security Administration, and the City of Dallas' Aviation Fund, the majority of the funds used were from the issuance of bonds. The Company guaranteed principal and interest payments on $456 million of such bonds issued by the LFAMC. As of December 31, 2016, $432 million of principal remained outstanding.

In conjunction with the Company's significant presence at Dallas Love Field, the Company agreed to manage the majority of the LFMP project. Based on the pertinent factors in place at the time the agreement was made, the Company utilized the accounting guidance provided for lessees involved in asset construction. As of December 31, 2016, the Company had recorded LFMP construction costs of $538 million within Assets constructed for others and had recorded a liability of $522 million within Construction obligation in its Consolidated Balance Sheet. Upon completion of

78

different phases of the LFMP project, the Company has placed the associated assets in service and has begun depreciating the assets over their estimated useful lives. In addition, upon the effective completion of construction, the Company noted the project assets did not meet the qualifications for sale and leaseback accounting due to the Company's continuing involvement with the facility, as defined; therefore, for financial reporting purposes, these assets will remain on the Company's books until the bonds issued by the City of Dallas are repaid. The corresponding LFMP liabilities are being reduced primarily through the Company's airport rental payments to the City of Dallas as the construction costs of this project are passed through to the Company via recurring airport rates and charges. A portion of these payments are reflected as Repayment of construction obligation in the Consolidated Statement of Cash Flows. The imputed interest rate associated with Construction obligation was nominal for 2015 and 2016.

During 2015, the City of Dallas issued additional bonds for the construction of a new parking garage at Dallas Love Field. The Company has not guaranteed the principal or interest payments on these bonds, but remains the accounting owner of this project. As of December 31, 2016, the Company recorded LFMP parking construction expenditures of $80 million with Assets constructed for others with a corresponding increase to Construction obligation on the accompanying Consolidated Balance Sheet.

Contingencies

The Company is from time to time subject to various legal proceedings and claims arising in the ordinary course of business, including, but not limited to, examinations by the Internal Revenue Service ("IRS"). The Company's management does not expect that the outcome of any of its currently ongoing legal proceedings or the outcome of any adjustments presented by the IRS, individually or collectively, will have a material adverse effect on the Company's financial condition, results of operations, or cash flow.

AirTran Long-Term Debt
      
AirTran Holdings is party to aircraft purchase financing facilities, and as of December 31, 2016, 18 Boeing 737 aircraft remained that were financed under floating-rate facilities. Each note is secured by a first mortgage on the aircraft to which it relates. The notes bear interest at a floating rate per annum equal to a margin plus the three or six-month LIBOR in effect at the commencement of each semi-annual or three-month period, as applicable. As of December 31, 2016, the weighted average interest rate was 2.40 percent. Principal and interest under the notes are payable semi-annually or every three months as applicable. As of December 31, 2016, the remaining debt outstanding may be prepaid without penalty under all aircraft loans provided under such facilities. The remaining notes mature in years 2017 to 2020. As discussed further in Note 10, a portion of the above floating-rate debt has been effectively converted to a fixed rate via interest rate swap agreements which expire as the underlying notes mature.

As of December 31, 2016, two Boeing 737 aircraft were financed under a fixed-rate facility. Each note is secured by a first mortgage on the aircraft to which it relates. As of December 31, 2016, the weighted average interest rate was 7.03 percent. Payments of principal and interest under the notes are due semi-annually. The remaining notes mature in years 2017 to 2018.

In October 2009, AirTran Holdings completed a public offering of $115 million of convertible senior notes due November 1, 2016. Such notes bore interest at 5.25 percent payable semi-annually, in arrears, on May 1 and November 1. As a result of the acquisition and subsequent dividends declared by the Company, the convertible senior notes were convertible into AirTran conversion units of 168.6576 per $1,000 in principal amount of such notes. Based on the terms of the merger agreement, the holders of these notes could receive shares of the Company’s common stock at a conversion rate of 54.5143 shares and $615.16 in cash per $1,000 in principal amount of such notes. During 2016, all the bonds matured, the majority of which had been converted prior to the maturity date, with approximately 6 million shares issued and cash paid of approximately $68 million.

Other Company Long-Term Debt

During November 2016, the Company issued $300 million senior unsecured notes due 2026. The notes bear interest at 3.00 percent. Interest is payable semi-annually in arrears on May 15 and November 15, beginning in 2017.

During October 2016, the Company entered into a term loan agreement providing for loans to the Company aggregating up to $215 million, to be secured by mortgages on seven of the Company's 737-800 aircraft. The Company has borrowed the full $215 million and secured this loan with the requisite seven aircraft mortgages. The loan matures on October 31, 2026, and is repayable via semi-annual installments of principal that begin April 30, 2018. The loan bears interest at the LIBO Rate (as defined in the term loan agreement) plus 1.10 percent, which equates to an initial rate of 2.36 percent, and interest is payable semi-annually in installments that begin April 30, 2017.

During third quarter 2016, the Company entered into term loan agreements to purchase the equity interest in four aircraft that were previously classified as operating leases, for a total of $20 million. As of December 31, 2016, the weighted average interest rate for the four term loan agreements was 7.94 percent. Payments of principal and interest under the loans are due semi-annually. The loans mature in years 2018 to 2021.

During November 2015, the Company issued $500 million senior unsecured notes due 2020. The notes bear interest at 2.65 percent, payable semi-annually in arrears on May 5 and November 5. Concurrently, the Company entered into a fixed-to-floating interest rate swap to convert the interest on these unsecured notes to a floating rate until their maturity. See Note 10 for further information on the interest-rate swap agreement.

During November 2014, the Company issued $300 million senior unsecured notes due 2019. The notes bear interest at 2.75 percent, payable semi-annually in arrears on May 6 and November 6. Concurrently, the Company entered into a fixed-to-floating interest rate swap to convert the interest on these unsecured notes to a floating rate until their maturity. See Note 10 for further information on the interest-rate swap agreement.

On July 1, 2009, the Company entered into a term loan agreement providing for loans to the Company aggregating up to $124 million, to be secured by mortgages on five of the Company’s 737-700 aircraft. The Company has borrowed the full $124 million and secured this loan with the requisite five aircraft mortgages. The loan matures on July 1, 2019, and is repayable semi-annually in installments of principal that began January 1, 2010. The loan bears interest at a fixed rate of 4.84 percent, and interest is payable semi-annually, which payments began on January 1, 2010. In September 2015, the Company prepaid $24 million on the loan agreement, which in turn released one of the encumbered aircraft. As such, the remaining four aircraft related to this transaction are still encumbered as of December 31, 2016.

On April 29, 2009, the Company entered into a term loan agreement providing for loans to the Company aggregating up to $332 million, to be secured by mortgages on 14 of the Company’s 737-700 aircraft. The Company borrowed the full $332 million and secured the loan with the requisite 14 aircraft mortgages. The loan matures on May 6, 2019, and is being repaid via quarterly installments of principal that began August 6, 2009. The loan bears interest at the LIBO Rate (as defined in the term loan agreement) plus 3.30 percent, and interest is payable quarterly, which payments began on August 6, 2009. Pursuant to the terms of the term loan agreement, the Company entered into an interest rate swap agreement to convert the variable rate on the term loan to a fixed 6.315 percent until maturity.

On May 6, 2008, the Company entered into a term loan agreement providing for loans to the Company aggregating up to $600 million, to be secured by first-lien mortgages on 21 of the Company’s 737-700 aircraft. On May 9, 2008, the Company borrowed the full $600 million and secured these loans with the requisite 21 aircraft mortgages. The loans mature on May 9, 2020, and are repayable quarterly in installments of principal, with the first payment made on August 9, 2008. The loans bear interest at the LIBO Rate (as defined in the term loan agreement) plus 0.95 percent, and interest is payable quarterly. Pursuant to the terms of the term loan agreement, the Company entered into an interest rate swap agreement to convert the variable rate on the term loan to a fixed 5.223 percent until maturity.


82

On October 3, 2007, grantor trusts established by the Company issued $500 million Pass Through Certificates consisting of $412 million 6.15 percent Series A certificates and $88 million 6.65 percent Series B certificates. A separate trust was established for each class of certificates. The trusts used the proceeds from the sale of certificates to acquire equipment notes in the same amounts, which were issued by the Company on a full recourse basis. Payments on the equipment notes held in each trust will be passed through to the holders of certificates of such trust. The equipment notes were issued for each of 16 Boeing 737-700 aircraft owned by the Company and are secured by a mortgage on each aircraft. Interest on the equipment notes held for the certificates is payable semi-annually, with the first payment made on February 1, 2008. Also beginning February 1, 2008, principal payments on the equipment notes held for both series of certificates are due semi-annually until the balance of the certificates mature on August 1, 2022. Prior to their issuance, the Company also entered into swap agreements to hedge the variability in interest rates on the Pass Through Certificates. The swap agreements were accounted for as cash flow hedges, and resulted in a payment by the Company of $20 million upon issuance of the Pass Through Certificates. The effective portion of the hedge is being amortized to interest expense concurrent with the amortization of the debt and is reflected in the above table as a reduction in the debt balance. The ineffectiveness of the hedge transaction was immaterial.

During December 2006, the Company issued $300 million senior unsecured notes due December 15, 2016. The notes bore interest at 5.75 percent. During fourth quarter 2009, the Company entered into a fixed-to-floating interest rate swap to convert the interest on these unsecured notes to a floating rate; however, the interest rate swap was terminated in 2015. The notes matured and were redeemed in full on December 15, 2016, utilizing available cash on hand.

During February 2005, the Company issued $300 million senior unsecured notes due 2017. The notes bear interest at 5.125 percent, payable semi-annually in arrears, with the first payment made on September 1, 2005.

In fourth quarter 2004, the Company entered into four identical 13-year floating-rate financing arrangements, whereby it borrowed a total of $112 million from French banking partnerships. Although the interest rates on the borrowings float, the Company estimated at inception that, considering the full effect of the “net present value benefits” included in the transactions, the effective economic yield over the 13-year term of the loans will be approximately LIBOR minus 45 basis points. Principal and interest are payable semi-annually on June 30 and December 31 for each of the loans, and the Company may terminate the arrangements in any year on either of those dates, under certain conditions. The Company pledged four aircraft as collateral for the transactions.
 
On February 28, 1997, the Company issued $100 million of senior unsecured 7.375 percent debentures due March 1, 2027. Interest is payable semi-annually on March 1 and September 1. The debentures may be redeemed, at the option of the Company, in whole at any time or in part from time to time, at a redemption price equal to the greater of the principal amount of the debentures plus accrued interest at the date of redemption or the sum of the present values of the remaining scheduled payments of principal and interest thereon, discounted to the date of redemption at the comparable treasury rate plus 20 basis points, plus accrued interest at the date of redemption. In January 2007, the Company entered into an interest rate swap agreement to convert this fixed-rate debt to a floating rate; however, the interest rate swap was terminated in December 2012.

The Company is required to provide standby letters of credit to support certain obligations that arise in the ordinary course of business. Although the letters of credit are an off-balance sheet item, the majority of the obligations to which they relate are reflected as liabilities in the Consolidated Balance Sheet. Outstanding letters of credit totaled $179 million at December 31, 2016.

The net book value of the assets pledged as collateral for the Company’s secured borrowings, primarily aircraft and engines, was $2.8 billion at December 31, 2016. In addition, the Company has pledged a total of up to 82 of its Boeing 737-700 and 30 of its Boeing 737-800 aircraft at a net book value of $2.7 billion, in the case that it has obligations related to its fuel derivative instruments with counterparties that exceed certain thresholds. See Note 10 for further information on these collateral arrangements.

As of December 31, 2016, aggregate annual principal maturities of debt and capital leases (not including amounts associated with interest rate swap agreements, interest on capital leases, amortization of capital lease incentives, and

83

amortization of purchase accounting adjustments) for the five-year period ending December 31, 2021, and thereafter, were $555 million in 2017, $323 million in 2018, $573 million in 2019, $797 million in 2020, $148 million in 2021, and $926 million thereafter.

7. LEASES

The Company's fleet included 51 aircraft on capital lease as of December 31, 2016, compared with 28 aircraft on capital lease, including one B717, as of December 31, 2015. Amounts applicable to these aircraft that are included in property and equipment were:

The majority of the Company’s terminal operations space, as well as 83 aircraft, were under operating leases at December 31, 2016. For aircraft operating leases and for terminal operations leases, expense is recorded on a straight-line basis and included in Aircraft rentals and in Landing fees and other rentals, respectively, in the Consolidated Statement of Income.

The aircraft leases generally can be renewed for one to five years at rates based on fair market value at the end of the lease term. Most aircraft leases have purchase options at or near the end of the lease term at fair market value, generally limited to a stated percentage of the lessor’s defined cost of the aircraft.

On July 9, 2012, the Company signed an agreement with Delta Air Lines, Inc. and Boeing Capital Corp. to lease or sublease all 88 of AirTran's B717s to Delta at agreed-upon lease rates. The first converted B717 was delivered to Delta in September 2013, and as of December 31, 2016, the Company had delivered all B717s to Delta. A total of 76 of the B717s are on operating lease, ten are owned, and two are on capital lease.


84

The Company paid the majority of the costs to convert the aircraft to the Delta livery and perform certain maintenance checks prior to the delivery of each aircraft. The agreement to pay these conversion and maintenance costs is a “lease incentive” under applicable accounting guidance. The sublease terms for the 76 B717s on operating lease and the two B717s on capital lease coincide with the Company's remaining lease terms for these aircraft from the original lessor, which range from approximately two to seven years. The leasing of the ten B717s that are owned by the Company is subject to certain conditions, and the lease terms are for up to six years, after which Delta will have the option to purchase the aircraft at the then-prevailing market value. The ten owned B717s are accounted for as sales type leases, the two B717s classified by the Company as capital leases are accounted for as direct financing leases, and the remaining 76 subleases are accounted for as operating leases with Delta. There are no contingent payments and no significant residual value conditions associated with the transaction.

The accounting for this transaction was based on the guidance provided for lease transactions. The Company recorded an initial charge of approximately $137 million during third quarter 2012, representing the remaining estimated cost, at the scheduled date of delivery of each B717 to Delta (including the conversion, maintenance, and other contractual costs to be incurred), of the Company's lease of the 76 B717s that are accounted for as operating leases, net of the future sublease income from Delta and the remaining unfavorable aircraft lease liability established as of the acquisition date. During 2014, the Company recorded an additional $22 million in expense for its revised estimate of conversion costs for these B717s, and an additional $9 million associated with the extension of time between when the Company removed the aircraft from revenue service, on December 28, 2014, and when they entered the conversion process. The charges recorded by the Company for this transaction were included as a component of Acquisition and integration costs in the Company's Consolidated Statement of Income and were included as a component of Other, net in Cash flows from operating activities in the Company's Consolidated Statement of Cash Flows, and the corresponding liability for this transaction, which was not material as of December 31, 2016 or 2015, is included as a component of Current liabilities and Other noncurrent liabilities in the Company's Consolidated Balance Sheet.

8. COMMON STOCK

The Company has one class of capital stock, its common stock. Holders of shares of common stock are entitled to receive dividends when and if declared by the Board of Directors and are entitled to one vote per share on all matters submitted to a vote of the Shareholders. At December 31, 2016, the Company had 60 million shares of common stock reserved for issuance pursuant to Employee equity plans (of which 31 million shares had not been granted) through various share-based compensation arrangements. See Note 9 to the Consolidated Financial Statements for information regarding the Company's equity plans.

9. STOCK PLANS

Share-based Compensation

The Company accounts for share-based compensation utilizing fair value, which is determined on the date of grant for all instruments. The Consolidated Statement of Income for the years ended December 31, 2016, 2015, and 2014, reflects share-based compensation expense of $33 million, $29 million, and $21 million, respectively. The total tax benefit recognized in earnings from share-based compensation arrangements for the years ended December 31, 2016, 2015, and 2014, was not material. As of December 31, 2016, there was $36 million of total unrecognized compensation cost related to share-based compensation arrangements, which is expected to be recognized over a weighted-average period of 1.7 years. The Company expects substantially all unvested awards to vest.

Under the Company’s Amended and Restated 2007 Equity Incentive Plan (“2007 Equity Plan”), it granted restricted stock units (“RSUs”) and performance-based restricted stock units (“PBRSUs”) to certain Employees during 2014, 2015, and 2016. Outstanding RSUs vest over three years, subject generally to the individual’s continued employment or service. The PBRSUs granted in May 2014, January 2015, and January 2016 are subject to the Company’s performance with respect to a three-year simple average of Return on Invested Capital, before taxes and excluding special items ("ROIC"), for the defined performance period and the individual’s continued employment or service. The number of PBRSUs vesting on the vesting date will be interpolated based on the Company's ROIC performance

85

and ranges from zero PBRSUs to 200 percent of granted PBRSUs. Forfeiture rates are estimated at the time of grant based on historical actuals for similar grants, and are trued-up to actuals over the vesting period. The Company recognizes all expense on a straight-line basis over the vesting period, with any changes in expense due to the number of PBRSUs expected to vest being modified on a prospective basis.

In addition, the Company granted approximately 27 thousand shares of unrestricted stock at a weighted average grant price of $42.90 in 2016, approximately 28 thousand shares at a weighted average grant price of $41.27 in 2015, and approximately 36 thousand shares at a weighted average grant price of $24.91 in 2014, to members of its Board of Directors.

A remaining balance of up to 22 million shares of the Company’s common stock may be issued pursuant to grants under the 2007 Equity Plan.

Employee Stock Purchase Plan

Under the amended 1991 Employee Stock Purchase Plan ("ESPP"), which has been approved by Shareholders, the Company is authorized to issue up to a remaining balance of 9 million shares of the Company’s common stock to Employees of the Company. These shares may be issued at a price equal to 90 percent of the market value at the end of each monthly purchase period. Common stock purchases are paid for through periodic payroll deductions. For the years ended December 31, 2016, 2015, and 2014, participants under the plan purchased 622 thousand shares, 597 thousand shares, and 792 thousand shares at average prices of $36.57, $36.40, and $23.17, respectively. The weighted-average fair value of each purchase right under the ESPP granted for the years ended December 31, 2016, 2015, and 2014, which is equal to the ten percent discount from the market value of the Common Stock at the end of each monthly purchase period, was $4.06, $4.04, and $2.68, respectively.

Taxes

A portion of the Company’s granted options qualify as incentive stock options for income tax purposes. As such, a tax benefit is not recorded at the time the compensation cost related to the options is recorded for book purposes due to the fact that an incentive stock option does not ordinarily result in a tax benefit unless there is a disqualifying disposition.

86

Grants of non-qualified stock options and RSUs result in the creation of a deferred tax asset, which is a temporary difference, until the time that the option is exercised or the RSU vests. With the issuance of ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, all excess tax benefits and tax deficiencies are recorded through the income statement. Due to the treatment of incentive stock options, non-qualified stock options, and RSUs for tax purposes, the Company’s effective tax rate from year to year is subject to variability.

10. FINANCIAL DERIVATIVE INSTRUMENTS

Fuel Contracts
    
Airline operators are inherently dependent upon energy to operate and, therefore, are impacted by changes in jet fuel prices. Furthermore, jet fuel and oil typically represent one of the largest operating expenses for airlines. The Company endeavors to acquire jet fuel at the lowest possible cost and to reduce volatility in operating expenses through its fuel hedging program. Although the Company may periodically enter into jet fuel derivatives for short-term timeframes, because jet fuel is not widely traded on an organized futures exchange, there are limited opportunities to hedge directly in jet fuel for time horizons longer than approximately 24 months into the future. However, the Company has found that financial derivative instruments in other commodities, such as West Texas Intermediate (“WTI”) crude oil, Brent crude oil, and refined products, such as heating oil and unleaded gasoline, can be useful in decreasing its exposure to jet fuel price volatility. The Company does not purchase or hold any financial derivative instruments for trading or speculative purposes.
    
The Company has used financial derivative instruments for both short-term and long-term time frames, and primarily uses a mixture of purchased call options, collar structures (which include both a purchased call option and a sold put option), call spreads (which include a purchased call option and a sold call option), put spreads (which include a purchased put option and a sold put option), and fixed price swap agreements in its portfolio. Although the use of collar structures and swap agreements can reduce the overall cost of hedging, these instruments carry more risk than purchased call options in that the Company could end up in a liability position when the collar structure or swap agreement settles. With the use of purchased call options and call spreads, the Company cannot be in a liability position at settlement, but does not have coverage once market prices fall below the strike price of the purchased call option.

For the purpose of evaluating its net cash spend for jet fuel and for forecasting its future estimated jet fuel expense, the Company evaluates its hedge volumes strictly from an “economic” standpoint and thus does not consider whether the hedges have qualified or will qualify for hedge accounting. The Company defines its “economic” hedge as the net volume of fuel derivative contracts held, including the impact of positions that have been offset through sold positions, regardless of whether those contracts qualify for hedge accounting. The level at which the Company is economically hedged for a particular period is also dependent on current market prices for that period, as well as the types of derivative instruments held and the strike prices of those instruments. For example, the Company may enter into “out-of-the-money” option contracts (including catastrophic protection), which may not generate intrinsic gains at settlement if market prices do not rise above the option strike price. Therefore, even though the Company may have an “economic” hedge in place for a particular period, that hedge may not produce any hedging gains at settlement and may even produce hedging losses depending on market prices, the types of instruments held, and the strike prices of those instruments.

For 2016, the Company had fuel derivative instruments in place for up to 46 percent of its fuel consumption. As of December 31, 2016, the Company also had fuel derivative instruments in place to provide coverage for up to 63 percent of its 2017 estimated fuel consumption, depending on where market prices settle. The following table provides information about the Company’s volume of fuel hedging for the years 2017 through 2019 on an “economic” basis considering current market prices:

(a) Due to the types of derivatives utilized by the Company and different price levels of those contracts, these volumes represent the maximum economic hedge in place and may vary significantly as market prices fluctuate.

Upon proper qualification, the Company accounts for its fuel derivative instruments as cash flow hedges. Generally, utilizing hedge accounting, all periodic changes in fair value of the derivatives designated as hedges that are considered to be effective are recorded in Accumulated other comprehensive income (loss) ("AOCI") until the underlying jet fuel is consumed. See Note 12. The Company’s results are subject to the possibility that periodic changes will not be effective, as defined, or that the derivatives will no longer qualify for hedge accounting. Ineffectiveness results when the change in the fair value of the derivative instrument exceeds the change in the value of the Company’s expected future cash outlay to purchase and consume jet fuel. To the extent that the periodic changes in the fair value of the derivatives are ineffective, the ineffective portion is recorded to Other (gains) losses, net, in the Consolidated Statement of Income. Likewise, if a hedge ceases to qualify for hedge accounting, any change in the fair value of derivative instruments since the last reporting period is recorded to Other (gains) losses, net, in the Consolidated Statement of Income in the period of the change; however, any amounts previously recorded to AOCI would remain there until such time as the original forecasted transaction occurs, at which time these amounts would be reclassified to Fuel and oil expense. When the Company has sold derivative positions in order to effectively “close” or offset a derivative already held as part of its fuel derivative instrument portfolio, any subsequent changes in fair value of those positions are marked to market through earnings. Likewise, any changes in fair value of those positions that were offset by entering into the sold positions and were de-designated as hedges are concurrently marked to market through earnings. However, any changes in value related to hedges that were deferred as part of AOCI while designated as a hedge would remain until the originally forecasted transaction occurs. In a situation where it becomes probable that a fuel hedged forecasted transaction will not occur, any gains and/or losses that have been recorded to AOCI would be required to be immediately reclassified into earnings. The Company did not have any such situations occur during 2014, 2015, or 2016.

Ineffectiveness is inherent in hedging jet fuel with derivative positions based in other crude oil related commodities. Due to the volatility in markets for crude oil and related products, the Company is unable to predict the amount of ineffectiveness each period, including the loss of hedge accounting, which could be determined on a derivative by derivative basis or in the aggregate for a specific commodity. This may result, and has resulted, in increased volatility in the Company’s financial results. Factors that have and may continue to lead to ineffectiveness and unrealized gains and losses on derivative contracts include: significant fluctuation in energy prices, the number of derivative positions the Company holds, significant weather events affecting refinery capacity and the production of refined products, and the volatility of the different types of products the Company uses in hedging. However, even though derivatives may not qualify for hedge accounting, the Company continues to hold the instruments as management believes derivative instruments continue to afford the Company the opportunity to stabilize jet fuel costs.

Accounting pronouncements pertaining to derivative instruments and hedging are complex with stringent requirements, including the documentation of a Company hedging strategy, statistical analysis to qualify a commodity for hedge accounting both on a historical and a prospective basis, and strict contemporaneous documentation that is required at the time each hedge is designated by the Company. The Company also examines the effectiveness of each individual hedge and its entire hedging program on a quarterly basis utilizing statistical analysis. This analysis involves utilizing regression and other statistical analyses that compare changes in the price of jet fuel to changes in the prices of the commodities used for hedging purposes.

All of the Company's fuel derivative instruments and interest rate swaps are subject to agreements that follow the netting guidance in the applicable accounting for derivatives and hedging. The types of derivative instruments the Company has determined are subject to netting requirements in the accompanying Consolidated Balance Sheet are those in which the Company pays or receives cash for transactions with the same counterparty and in the same currency via one net payment or receipt. For cash collateral held by the Company or provided to counterparties, the Company nets such amounts against the fair value of the Company's derivative portfolio by each counterparty. The Company has elected to utilize netting for both its fuel derivative instruments and interest rate swap agreements and also classifies such amounts as either current or noncurrent, based on the net fair value position with each of the Company's counterparties in the Consolidated Balance Sheet.

The Company's application of its netting policy associated with cash collateral differs depending on whether its derivative instruments are in a net asset position or a net liability position. If its fuel derivative instruments are in a net asset position with a counterparty, cash collateral amounts held are first netted against current outstanding derivative amounts associated with that counterparty until that balance is zero, and then any remainder is applied against the fair value of noncurrent outstanding derivative instruments. If the Company's fuel derivative instruments are in a net liability position with the counterparty, cash collateral amounts provided are first netted against noncurrent outstanding derivative amounts associated with that counterparty until that balance is zero, and then any remainder is applied against the fair value of current outstanding derivative instruments.

The Company has the following recognized financial assets and financial liabilities resulting from those transactions that meet the scope of the disclosure requirements as necessitated by applicable accounting guidance for balance sheet offsetting:

The Company also recorded expense associated with premiums paid for fuel derivative contracts that settled/expired during 2016, 2015, and 2014 of $153 million, $124 million, and $62 million, respectively. These amounts are excluded from the Company’s measurement of effectiveness for related hedges and are included as a component of Other (gains) losses, net, in the Consolidated Statement of Income.

The fair values of the derivative instruments, depending on the type of instrument, were determined by the use of present value methods or option value models with assumptions about commodity prices based on those observed in underlying markets or provided by third parties. Included in the Company’s cumulative net unrealized losses from fuel hedges as of December 31, 2016, recorded in AOCI, were approximately $302 million in unrealized losses, net of taxes, which are expected to be realized in earnings during the twelve months subsequent to December 31, 2016.

Interest Rate Swaps

The Company is party to certain interest rate swap agreements that are accounted for as either fair value hedges or cash flow hedges, as defined in the applicable accounting guidance for derivative instruments and hedging. Several of the Company's interest rate swap agreements qualify for the “shortcut” method of accounting for hedges, which dictates that the hedges are assumed to be perfectly effective, and, thus, there is no ineffectiveness to be recorded in earnings. For the Company’s interest rate swap agreements that do not qualify for the "shortcut" method of accounting, ineffectiveness is required to be measured at each reporting period. The ineffectiveness associated with all of the Company’s, including AirTran Holdings', interest rate swap agreements for all periods presented was not material.
    
The fair values of the interest rate swap agreements, which are adjusted regularly, have been aggregated by counterparty for classification in the Consolidated Balance Sheet. Agreements totaling a net liability of $35 million are fair value hedges, cash flow hedges, and interest rate derivatives not utilizing hedge accounting, are classified as a component of Other noncurrent liabilities. The corresponding adjustment related to the net liability associated with the Company’s cash flow hedges is to AOCI, fair value hedges is to the carrying value of the long-term debt, and interest rate derivatives not utilizing hedge accounting is to Interest expense. See Note 12.

The Company has fixed-to-floating interest rate swap agreements in place associated with its $500 million 2.65 percent Notes due 2020 and its $300 million 2.75 percent Notes due 2019 that are accounted for as fair value hedges. As a result of the fixed-to-floating interest rate swap agreements in place, the average floating rate recognized during 2016 was approximately 2.03 percent on the $500 million Note, and approximately 1.85 percent on the $300 million Note, based on actual and forward rates as of December 31, 2016.

The Company has floating-to-fixed interest rate swap agreements associated with its $600 million floating-rate term loan agreement due 2020 and its $332 million term loan agreement due 2019 that are accounted for as cash flow hedges. These interest rate hedges have fixed the interest rate on the $600 million floating-rate term loan agreement at 5.223 percent until maturity, and for the $332 million term loan agreement at 6.315 percent until maturity.
        

92


There are also a number of interest rate swap agreements, which convert a portion of AirTran Holdings' floating-rate debt to a fixed-rate basis for the remaining life of the debt, thus reducing the impact of interest rate changes on future interest expense and cash flows. Under these agreements, which expire between 2017 and 2020, it pays fixed rates between 4.35 percent and 6.435 percent and receives either three-month or six-month LIBOR on the notional values. The notional amount of outstanding debt related to interest rate swaps as of December 31, 2016, was $166 million. These interest rate swap arrangements were designated as cash flow hedges as of the acquisition date, and subsequently de-designated during fourth quarter 2016 as the Company no longer believes these hedges will be highly effective in offsetting future cash flows. The mark-to-market impact associated with these hedges for all periods presented was not material.

Credit Risk and Collateral

Credit exposure related to fuel derivative instruments is represented by the fair value of contracts that are an asset to the Company at the reporting date. At such times, these outstanding instruments expose the Company to credit loss in the event of nonperformance by the counterparties to the agreements. However, the Company has not experienced any significant credit loss as a result of counterparty nonperformance in the past. To manage credit risk, the Company selects and periodically reviews counterparties based on credit ratings, limits its exposure with respect to each counterparty, and monitors the market position of the fuel hedging program and its relative market position with each counterparty. At December 31, 2016, the Company had agreements with all of its active counterparties containing early termination rights and/or bilateral collateral provisions whereby security is required if market risk exposure exceeds a specified threshold amount based on the counterparty credit rating. The Company also had agreements with counterparties in which cash deposits, letters of credit, and/or pledged aircraft are required to be posted whenever the net fair value of derivatives associated with those counterparties exceeds specific thresholds. The following table provides the fair values of fuel derivatives, amounts posted as collateral, and applicable collateral posting threshold amounts as of December 31, 2016, at which such postings are triggered:

11. FAIR VALUE MEASUREMENTS

Accounting standards pertaining to fair value measurements establish a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

As of December 31, 2016, the Company held certain items that are required to be measured at fair value on a recurring basis. These included cash equivalents, short-term investments (primarily treasury bills and certificates of deposit), interest rate derivative contracts, fuel derivative contracts, and available-for-sale securities. The majority of the Company’s short-term investments consist of instruments classified as Level 1. However, the Company has certificates of deposit, commercial paper, and Eurodollar time deposits that are classified as Level 2, due to the fact that the fair value for these instruments is determined utilizing observable inputs in non-active markets. Other available-for-sale securities primarily consist of investments associated with the Company’s excess benefit plan.

The Company’s fuel and interest rate derivative instruments consist of over-the-counter contracts, which are not traded on a public exchange. Fuel derivative instruments include swaps, as well as different types of option contracts, whereas interest rate derivatives consist solely of swap agreements. See Note 10 for further information on the Company’s derivative instruments and hedging activities. The fair values of swap contracts are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. Therefore, the Company has categorized these swap contracts as Level 2. The Company’s Treasury Department, which reports to the Chief Financial Officer, determines the value of option contracts utilizing an option pricing model based on inputs that are either readily available in public markets, can be derived from information available in publicly quoted markets, or are provided by financial institutions that trade these contracts. The option pricing model used by the Company is an industry standard model for valuing options and is the same model used by the broker/dealer community (i.e., the Company’s counterparties). The inputs to this option pricing model are the option strike price, underlying price, risk free rate of interest, time to expiration, and volatility. Because certain inputs used to determine the fair value of option contracts are unobservable (principally implied volatility), the Company has categorized these option contracts as Level 3. Volatility information is obtained from external sources, but is analyzed by the Company for reasonableness and compared to similar information received from other external sources. The fair value of option contracts considers both the intrinsic value and any remaining time value associated with those derivatives that have not yet settled. The Company also considers counterparty credit risk and its own credit risk in its determination of all estimated fair values. To validate the reasonableness of the Company’s option pricing model, on a monthly basis, the Company compares its option valuations to third party valuations. If any significant differences were to be noted, they would be researched in order to determine the reason. However, historically, no significant differences have been noted. The Company has consistently applied these valuation techniques in all periods presented and believes it has obtained the most accurate information available for the types of derivative contracts it holds.

Included in Other available-for-sale securities are the Company's investments associated with its deferred compensation plans, which consist of mutual funds that are publicly traded and for which market prices are readily available. These plans are non-qualified deferred compensation plans designed to hold contributions in excess of limits established by the Internal Revenue Code of 1986, as amended. The distribution timing and payment amounts under these plans are

94

made based on the participant's distribution election and plan balance. Assets related to the funded portions of the deferred compensation plans are held in a rabbi trust, and the Company remains liable to these participants for the unfunded portion of the plans. The Company records changes in the fair value of the assets in the Company's earnings.

The following tables present the Company’s assets and liabilities that are measured at fair value on a recurring basis at December 31, 2016, and December 31, 2015:

The significant unobservable input used in the fair value measurement of the Company’s derivative option contracts is implied volatility. Holding other inputs constant, a significant increase (decrease) in implied volatility would result in a significantly higher (lower) fair value measurement, respectively, for the Company’s derivative option contracts.

The following table presents a range of the unobservable inputs utilized in the fair value measurements of the Company’s fuel derivatives classified as Level 3 at December 31, 2016:

The carrying amounts and estimated fair values of the Company’s long-term debt (including current maturities), as well as the applicable fair value hierarchy tier, at December 31, 2016, are presented in the table below. The fair values of the Company’s publicly held long-term debt are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets; therefore, the Company has categorized these agreements as Level 2. Eight of the Company’s debt agreements are not publicly held. The Company has determined the estimated fair value of this debt to be Level 3, as certain inputs used to determine the fair value of these agreements are unobservable. The Company utilizes indicative pricing from counterparties and a discounted cash flow method to estimate the fair value of the Level 3 items.

13. EMPLOYEE RETIREMENT PLANS

Defined Contribution Plans

Southwest has defined contribution plans covering substantially all of its Employees. Contributions under all defined contribution plans are primarily based on Employee compensation and performance of the Company. The Company sponsors Employee savings plans under section 401(k) of the Internal Revenue Code of 1986, as amended, which include Company matching contributions. In addition, the Southwest Airlines Co. ProfitSharing Plan (ProfitSharing Plan) is a defined contribution plan to which the Company may contribute a percentage of its eligible pre-tax profits, as defined, on an annual basis. No Employee contributions to the ProfitSharing Plan are allowed.

Amounts associated with the Company's defined contribution plans expensed in 2016, 2015, and 2014, reflected as a component of Salaries, wages, and benefits, were $937 million, $945 million, and $644 million, respectively.

Postretirement Benefit Plans


99

The Company provides postretirement benefits to qualified retirees in the form of medical and dental coverage. Employees must meet minimum levels of service and age requirements as set forth by the Company, or as specified in collective-bargaining agreements with specific workgroups. Employees meeting these requirements, as defined, may use accrued unused sick time to pay for medical and dental premiums from the age of retirement until age 65.

The following table shows the change in the accumulated postretirement benefit obligation (APBO) for the years ended December 31, 2016 and 2015:

All plans are unfunded, and benefits are paid as they become due. Estimated future benefit payments expected to be paid are $7 million in 2017, $8 million in 2018, $9 million in 2019, $10 million in 2020, $12 million in 2021, and $90 million for the next five years thereafter.

The funded status (the difference between the fair value of plan assets and the projected benefit obligations) of the Company’s consolidated benefit plans are recognized in the Consolidated Balance Sheet, with a corresponding adjustment to AOCI. The following table reconciles the funded status of the plans to the accrued postretirement benefit cost recognized in Other non-current liabilities on the Company’s Consolidated Balance Sheet at December 31, 2016 and 2015.

Unrecognized prior service cost is expensed using a straight-line amortization of the cost over the average future service of Employees expected to receive benefits under the plans. Actuarial gains are amortized utilizing the minimum amortization method. The following actuarial assumptions were used to account for the Company’s postretirement benefit plans at December 31, 2016, 2015, and 2014:

The assumed healthcare cost trend rate is assumed to remain at 7.08% for 2017, then decline gradually to 5.19% by 2027 and remain level thereafter.

The assumed healthcare cost trend rates have a significant effect on the amounts reported for the consolidated postretirement plans. A one percent change in all healthcare cost trend rates used in measuring the APBO at December 31, 2016, would have the following effects:

The selection of a discount rate is made annually and is selected by the Company based upon comparison of the expected future cash flows associated with the Company’s future payments under its consolidated postretirement obligations to a yield curve created using high quality bonds that closely match those expected future cash flows. This rate decreased during 2016 due to market conditions. The assumed healthcare trend rate is also reviewed at least annually and is determined based upon both historical experience with the Company’s healthcare benefits paid and expectations of how those trends may or may not change in future years.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders
Southwest Airlines Co.

We have audited the accompanying consolidated balance sheet of Southwest Airlines Co. as of December 31, 2016 and 2015, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2016. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Southwest Airlines Co. at December 31, 2016 and 2015, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2016 in conformity with U.S. generally accepted accounting principles.

As discussed in Note 1 to the consolidated financial statements, the Company has changed its method of accounting for its co-brand credit card agreement and applied the amendments to the FASB Accounting Standard Codification resulting from Accounting Standards Update No. 2009-13, Multiple Deliverable Revenue Arrangements, effective July 1, 2015.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Southwest Airlines Co.’s internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) and our report dated February 7, 2017 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders
Southwest Airlines Co.

We have audited Southwest Airlines Co.’s internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) (the COSO criteria). Southwest Airlines Co.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying “Management’s Annual Report on Internal Control Over Financial Reporting.” Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 (3) 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.

In our opinion, Southwest Airlines Co. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Southwest Airlines Co. as of December 31, 2016 and 2015, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2016 and our report dated February 7, 2017 expressed an unqualified opinion thereon.

(a) Includes the impact of the Agreement with Chase and the resulting required change in accounting methodology. The impact of this change during third quarter and fourth quarter 2015 resulted in increases to Operating revenue of approximately $303 million and $124 million, respectively, and increased Basic and Diluted net income per share by approximately $.24 in third quarter 2015 and by approximately $.10 in fourth quarter 2015. The impact of this change resulted in an increase to Operating revenue during first quarter 2016 of approximately $115 million and increased Basic and Diluted net income per share by approximately $.10 and $.09, respectively. The impact of this change resulted in an increase to Operating revenue during second quarter 2016 of approximately $137 million, and increased Basic and Diluted net income per share by approximately $.12 and $.11, respectively. See Note 1 for further detail.

(b) During second quarter 2016, the Company early adopted ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting, with an effective date as of January 1, 2016. The prospective method of adoption of this standard resulted in the recognition of $2 million of excess tax benefits to the Company's income tax provision for the six months ended June 30, 2016, but which were related to first quarter 2016. For this presentation and in future periods in which first quarter 2016 results are reported, these amounts are reflected in the appropriate period. The adoption had no impact to net income per share amounts. See Note 2 for further information.

Item 9.        Changes in and Disagreements With Accountants on Accounting and Financial Disclosure
None.
 
Item 9A.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures. The Company maintains disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act (the “Exchange Act”)) designed to provide reasonable assurance that the information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. These include controls and procedures designed to ensure that this information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures as of December 31, 2016. Based on this evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2016, at the reasonable assurance level.

Management’s Annual Report on Internal Control over Financial Reporting. Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act). The Company’s internal control over financial reporting is a process, under the supervision of the Company’s Chief Executive Officer and Chief Financial Officer, designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance of achieving their control objectives.

Management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company’s internal control over financial reporting as of December 31, 2016. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework (2013 Framework). Based on this evaluation, management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, concluded that, as of December 31, 2016, the Company’s internal control over financial reporting was effective.

Ernst & Young, LLP, the independent registered public accounting firm who audited the Company’s Consolidated Financial Statements included in this Form 10-K, has issued a report on the Company’s internal control over financial reporting, which is included herein.

Changes in Internal Control over Financial Reporting. There were no changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) during the quarter ended December 31, 2016, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
