While aircraft and technology enable us to provide air transportation, we recognize this is fundamentally a people business. Our employees maintain and strengthen our relationships with customers,guests, and our success depends on our employees working together to successfully execute on our strategy.

We have been the leader in the industry for on-time performance among major airlines for the past sixseven years. For achieving safety, customer service, operational and financial goals, we rewarded our employees with a record $120$127 million in incentive pay during 2015.2016. Including incentives earned during the year prior to the acquisition by Virgin America employees, the total is $159 million.

In support of the communities that we serve, we strive to be an industry leader in environmental and community stewardship. In 2015, Air Group2016, we improved fuel efficiency by 2.2%1.4% from the prior year, as measured by available seat miles flown per gallon. We also flew the first two commercial flights using sustainable alcohol-to-jet biofuel made from U.S. grown corn and alternative jet fuel made from forest residuals, highlighting our commitment to environmental stewardship. Our combined fleet is one of the youngest, most fuel-efficient fleets in North America and we look forward to further enhancements in this area.

As we look to the future, we will build on theour success of the past few years by executing our strategic plan in the Five Focus Areas:following areas:

SafetyBe Safe and ComplianceOn time
We have an unwavering commitment to run a safe and compliant operation, and we will not compromise this commitment in the pursuit of other initiatives. Alaska and Horizon are awaiting final FAA certificationwere the first U.S. major airlines to receive Federal Aviation Administration ("FAA") validation and acceptance of our fully-implemented Safety Management System (SMS).("SMS") in the third quarter of 2016. SMS helps identify and manage risk and builds a sustainable culture of safety for every Air Group employee.employees. We have an initiative to add Virgin America to the SMS program in 2017. Once again, for 2015,2016, 100% of our Alaska and Horizon aircraft technicians completed the requirements for the FAA's "Diamond Certificate of Excellence" award. This is the 14th15th consecutive year Alaska Airlines has received the award and the 14th15th time in the last 1617 years for Horizon. In 2014, we launched Ready, Safe, Go - a safety campaign designedWe also believe that maintaining safe and compliant operations, through adherence to increase safety awareness across thewell defined processes and ensuring every Air Group System. With our Ready, Safe, Go program in its second year, employee

The rigor we apply to running a strong culture of safety continues to increase. In 2015,safe and compliant operation has resulted in Alaska and Horizon employees madebeing named the No. 1 on-time carrier in North America for the seventh year in a “Personal Commitment to Safety” during facilitated discussions with company leaders. row by FlightStats.
Focus on People Focus
Our success depends on our employees.people. Higher employee engagement drives higher productivity, superior execution and better customer service, which is why we listen to our employees for feedback in shaping our strategy. Employee engagement scores from our annual employee survey are at historical highs. In addition to the "Beyond Service"We have designed customer-service workshops and leadership training that cover virtually all employees and do these on an ongoing basis. As we integrate Alaska and Virgin America, in January 2017 we rolled out "Momentum" training for all Virgin America employees to help bridge the two airlines and blend our customer-facingcultures. For our Horizon employees, allwe are conducting "QX Factor," a program with the goal of Air Group's leaders participated in a multi-day leadership training called "Gear Up 2." This is the second phase of our award-winning leadership training where our leaders spent time focusing on several of our core leadership principles in an effort to give them the tools they need to effectively lead a highly-engaged workforce.improving culture, engagement and communication.

We understand that aligning our employees' goals with the Company'sAir Group's goals is important in achieving success. AllThe majority of Air Group employees, including Virgin America employees starting in 2017, participate in our Performance-Based Pay (PBP)("PBP") and Operational Performance Rewards (OPR)("OPR") programs, which encourage employees to work together to achieve metrics related to safety, profitability, on-time performance, low costs and customer loyalty and satisfaction. Over the last five years, our incentive programs have paid out on average, over 8.6%8.7% of annual pay, or more than one month's pay, for most employees. This is consistent with one of our guiding principles that we want to pay our people well with a goal of reaching the industry’s best productivity over time. To that end, we are currently in long-term agreements with all of our major work groups, which provide the Company, employees, and investors with long-term stability.

Hassle-Free Customer Experience
We want to be the easiest airline to fly. In each step of the customer's journey, from bookingBuild a ticket to check-in, from flying in our aircraft to claiming baggage at the final destination, we want to provide a hassle-free experiencedeep emotional connection for our customers. Our industry-leading on-time performance for the past six years reflects the reliable service we provide our customers, and we were the first airline to guarantee checked baggage delivery to the carousel within 20 minutes. Customers can tag their own bags at airport kiosks, or from their homes, and we have fingerprint scan entry to our airport lounges. We lead the travel industry in mobile innovation with a 5-star rated iPhone app, and Android and Microsoft apps that allow passengers to purchase tickets, check-in, upgrade seats, and reserve food for the flight - all with helpful notifications that inform customers when there are changes to their flights. The Transportation Security Administration (TSA) Pre-Check Program is available in 60 of our locations, which allows eligible customers to opt-in for reduced screening requirements. To hear directly from our customers, we have the Alaska Listens survey with five simple questions designed to get timely feedback - and we guarantee a response within 72 hours if there is an issue that needs to be resolved. As passengers take more control of their travel experience, we are able to reduce the time it takes a customer to move from the airport curb to the aircraft.brand

Energetic and Compelling Brand
We want to be recognized as the preferred airline to fly.fly for people living on the West Coast. In January 2016, we introduced a bold new brand expression, including an updated identity, livery, and look and feel for our digital and physical experiences. In January 2017, subsequent to year end, we were the first airline to launch Free Chata feature that allows our guests to text for free in-flight. We believe there’sthere is an opportunity to deepen the emotional connection with our customersguests as we continue to expand and grow. Our updated brand expression draws upon our rich heritage while infusing it with additional warmth and energy - to better reflect how customersguests feel about our brand and the great service that we pride ourselves in delivering.

We continue to invest in a better customer experience. Onboard, customersguests will continue to enjoy more of what they love with free and premium entertainment direct to their devices, Pacific Northwest-inspired food and beverages, and custom leather seats with power outlets for laptops and personal devicesat every seat and larger overhead bins for carry-on bags. In the fall of 2016,As mentioned previously, we will introduce ahave also recently launched our new Premium Class section in the main cabin with increased pitchlegroom and other amenities.amenities and improved our First Class with five additional inches of leg room.

Defend and grow our customer base
The merger with Virgin America provides an amazing opportunity for our new Alaska Air Group. We have a network that provides unparalleled utility and options for our guests living on the West Coast. Competition in our markets is fierce and we know we must defend our customer base as we use our combined network as an opportunity to grow that base. We will be introducing new guests to our award-winning service, Mileage Plan™ program, and affinity credit card as we grow our network. Guests from our airlines already benefit from codeshare and reciprocal frequent flyer benefits, including earning and redeeming rewards on both carriers. Elite members of the Virgin America Elevate® program and Alaska's Mileage Plan™ also continuereceive priority boarding on both carriers. We work hard to invest in advertising across markets. We recently renewedensure our partnership with Seattle Seahawks quarterback Russell Wilson, asguests have a great experience on our Chief Football Officer. We also announcedairlines and are provided an exceptional product at a ten-year sponsorship with the University of Washington, which includes naming rights to the Alaska Airlines Field at Husky Stadium and the Alaska Airlines Arena at Hec Edmunson Pavillion, among other benefits.low fare.

Low Fares, Low Costs
Win with low costs and Network Growthlow fares
We believe that our low-fare model gives us a competitive advantage by providing value to and building trust with our guests. We also know that, in order to provide low fares for customers in aour growing network, of destinations, while returning value to our shareholders, it is imperative for us to maintain a competitive cost structure. In 2015,2016, we lowered our unit costs, excluding fuel, by 0.7%0.8% on a consolidated basis, representing the sixthseventh consecutive year of annual reduction. We achieved this through a continued focus on productivity, cost management, and networkby leveraging capacity growth. We increased employee productivity in 20152016 and will continue to focus on that metric as we leverage growth.grow. We also manage fuel costs by flying larger, more fuel-efficient aircraft, which have increased our fuel efficiency as measured by available seat miles flown per gallon by 5.6%7.0% over the last five years. Additionally,As we have added split-scimitar winglets to 94 aircraft, whichintegrate Virgin America into our operations, we are expected to increase fuel efficiency by

approximately 1.5% per aircraft. Looking forward, we have committed to purchasing 31 737-900ERachieving our stated cost and 37 737-MAX aircraft with deliveries from 2016 to 2022, and two Q400 aircraft with deliveries in 2018, although these are subject to change. In addition, we will increase regional capacity by adding 18 E175s with contractual deliveries from 2016 to 2017 and we may order an additional 30 regional jets with delivery beginning in 2017 if we reach acceptable commercial terms. These aircraft deliveries position us for growth and help to ensurerevenue synergy goals. It is critical that we willachieve these goals in order to continue to operate the most fuel-efficient aircraft available for the foreseeable future.our cost reduction efforts.

In 2015,During fiscal 2016, we added 2017 new markets to our route structure. We continued to strengthen our Seattle network to offer further utility to our customers by offering non-stop flights to markets like New York (JFK), Charleston, Raleigh-Durham, Nashville, Oklahoma City, and Milwaukee. We also added flying from Los Angeles (LAX) to Liberia and San Jose, Costa Rica and Baltimore.

Miles can be earned by flying on Alaska or on one of our 1624 airline partners, or by using the Alaska Airlines Visa Signaturecredit card, or through other non-airline partners. Our extensive list of airline partners includes carriers associated with twoeach of the three major global alliances, (Oneworld and SkyTeam), making it easier for our members to earn miles and reach preferredelite status in our Mileage Plan™,frequent flyer programs and have access to a large network of over 900 worldwide travel


destinations. Further, members can receive 25,00030,000 bonus miles (30,000 beginning in the Spring of 2016) upon signing up for the Alaska Airlines Visa Signature card and earn triple miles on purchases made on Alaska Airlines flights or on alaskaair.com. Alaska Airlines Visa Signature cardholders also receive an annual companion ticket that allows members to purchase an additional ticket for $99 plus taxes, with no restrictions or black-out dates, and a free first checked bag for all partiesup to seven people traveling in the same itinerary. Earned miles can be redeemed for flights on Alaska Airlinesour airlines or on any of our partner airlines, or for upgrades to First Class and Premium Class on Alaska Airlines for as low as 15,000 miles.Airlines. All of these benefits give our Mileage Plan™ members more value for their travel on Alaska, Airlines, which ledleading us to our Mileage Plan™ receivingreceive the highest ranking by frequent fliers in the first-evercustomer satisfaction amongst traditional carriers in North America from J.D.

AGREEMENTS WITH OTHER AIRLINES

Our agreements fall into three different categories: Frequent Flier,Flyer, Codeshare and Interline agreements. Frequent FlierFlyer agreements offer mileage credits and redemptions for our Mileage Plan™ and Elevate® members. Alaska offers one of the most comprehensive frequent flierflyer programs for our Mileage Plan™ members through our frequent flierflyer partnerships with 1624 domestic and international carriers.

Codeshare agreements allow one or more marketing carriers to sell seats on a single operating carrier that services passengers under multiple flight numbers. The sale of codeshare seats can vary depending on the sale arrangement. For example, in a free-sale arrangement, the marketing carrier sells the operating carrier's inventory without any restriction; whereas in a block space arrangement, a fixed amount of seats areis sold to the marketing carrier by the operating carrier. The interchangeability of the flight code between carriers provides a greater selection of flights for customers, along with increased flexibility for mileage accrual and redemption.

Interline agreements allow airlines to jointly offer a competitive, single-fare itinerary to customers traveling via multiple carriers to a final destination. An interline itinerary offered by one airline may not necessarily be offered by the other, and the fares collected from passengers are prorated and distributed to interline partners according to preexisting agreements between the carriers. Frequent Flier, Codeshare,flyer, codeshare and Interlineinterline agreements help increase our traffic and revenue by providing more route choices to customers.our guests.

We have marketing alliances with a number of airlines that provide frequent flierflyer and codesharing opportunities. Alliances are an important part of our strategy and enhance our revenues by:
 
offering our customersguests more travel destinations and better mileage credit/redemption opportunities, including elite qualifying miles on all of our major U.S. and international airline partners;

giving our Mileage Plan™frequent flyer program a competitive advantage because of our partnership with carriers from twoall three of the three major global alliances (Oneworld and SkyTeam);alliances;
 
giving us access to more connecting traffic from other airlines; and
 
providing members of our alliance partners’ frequent flierflyer programs an opportunity to travel on Alaska, Virgin America and itsour regional affiliates while earning mileage credit in our partners’ programs.
 
Most of our codeshare relationships are free-sale codeshares, where the marketing carrier sells seats on the operating carrier’s flights from the operating carrier’s inventory, but takes no inventory risk. Our marketing agreements have various termination dates, and at any time, one or more may be in the process of renegotiation.renegotiation at any time.

On December 19, 2016 we announced the termination of our codeshare agreement with Delta Air Lines ("Delta"), effective April 30, 2017. Our interline agreement with Delta will continue. We expect the impact to our guests in 2017 to be minimal due to growth in Alaska's own network, in large part from our acquisition of Virgin America, and our ability to codeshare with other


partners. We also believe the financial exposure from the termination of our codeshare agreement with Delta will be immaterial to our financial results in 2017.

OTHER REVENUE

Other revenue consists of freight and mail, revenue,certain frequent flyer and ancillary revenue. While some of our product features are included in our base pricing, we have unbundled certain ancillary features that our guests separately value. Major ancillary revenue such asproducts include checked bag fees, change fees on-board food and beverage,lounge memberships. We also promote and Boardroom membership.sell products in-flight to enhance the guest experience, including our Tom Douglas signature meals, snacks, alcoholic beverages, in-flight entertainment and Wi-Fi. Total other revenue, excluding Mileage Plan™frequent flyer program revenue, represents about 7% of our total revenues. In recent years, we have seen growth in our ancillary revenue as we expand services on-board such as Tom Douglas signature meals, in-flight entertainment, and Wi-Fi. Although we do charge bag fees, we offer a 20-minute bag guarantee so that we deliver value to our customers through fast, reliable service. In 2015, we added a free bag as a permanent feature of our affinity credit card. As we focus on ways to better serve our customers, we expect our ancillary revenues will continue to grow.

GENERAL

The airline industry is highly competitive and subject to various uncertainties, and has historically been characterized by low profit margins. Uncertainties include generalincluding economic conditions, volatile fuel prices, industry instability, new competition, a largely unionized work force, the need to finance large capital expenditures and the related availability of capital, government regulation, regulation—including taxes and fees and potential aircraft incidents. Airlines have high fixed costs, primarily for wages, aircraft fuel, aircraft ownership and facilities rents. Because expenses of a flight do not vary significantly based on the number of passengers carried, a relatively small change in the number of passengers or in pricing has a disproportionate effect on an airline’s operating and financial results. In other words, a minor shortfall in expected revenue levels could cause a disproportionately negative impact on our operating and financial results. Passenger demand and ticket prices are, to a large measure, influenced by the general state of the economy, current global economic and political events, and total available airline seat capacity.

In 20152016, the airline industry reported recordhistorically high revenues and profits, as the global economy continued to recover and oil prices declined significantly.remained low. As the industry strengthens, airlines are now making significant investments in airports, in new planes and in new services to differentiate their customer service offering. Thus, the level of competition is expected to increase.

FUEL

Our business and financial results are highly affected by the price and potentially, the availability of aircraft fuel. The cost of aircraft fuel is volatile and outside of our control, and it can have a significant and immediate impact on our operating results. Over the past five years, aircraft fuel expense ranged from 22%18% to 35% of operating expenses. Fuel prices are impacted by changes in both the price of crude oil and refining margins and can vary by region in the U.S.
 
The prices we have paid for crude oil on an average annual price of crude oil inbasis for the lastpast five years hashave ranged from a low of $49$43 per barrel in 2015 from2016 to a high of $98 in 2013. For us, a $1 per barrel change in the price of oil equates to approximately $12$18 million of fuel cost annually. Said another way, a one-cent change in our fuel price per gallon will impact our expected annual fuel cost by approximately $5$7 million per year.


8




Refining margins, which represent the price of refining crude oil into aircraft fuel, are a smaller portion of the overall price of jet fuel but also contributed to the price volatility in recent years. Average annual refining margin prices have fluctuated between $20$13 per barrel and $36 per barrel in the last five years, and averaged $20$13 in 2015.2016.



Generally, West Coast jet fuel prices are somewhat higher and more volatile than prices in the Gulf Coast or on the East Coast. Our average raw fuel cost per gallon decreased 19% in 2016, 39% in 2015 decreasedand 6% in 2014, and 4% in 2013.2014.

The percentages of our aircraft fuel expense by crude oil and refining margins, as well as the percentage of our aircraft fuel expense of operating expenses are as follows:

(b)Other includes gains and losses on settled fuel hedges, unrealized mark-to-market fuel hedge gains or losses, taxes and other into-plane costs.

We use crude oil call options as hedges to decrease our exposure to the volatility of jet fuel prices. Historically, we have had jet fuel refining margin swap contracts, but we discontinued the use of the refining margin swaps in the third quarter of 2014. Call options effectively cap our pricing for crude oil, limiting our exposure to increasing fuel prices for about half of our planned fuel consumption. With call options, we are hedged against spikes in crude oil prices, and during a period of decline in crude oil prices, we only forfeit cash previously paid for hedge premiums. Currently, we startWe begin hedging approximately 18 months in advance of crude oil consumption.

We believe that operating fuel-efficient aircraft is the best hedge against high fuel prices. Alaska operates an all-Boeing 737 fleet, Virgin America operates an all-Airbus A320 family fleet, and Horizon currently operates an all-Bombardier Q400 turboprop fleet. Air Group's fuel-efficiency rate expressed in available seat miles flown per gallon (ASMs/g)("ASMs/g") improved from 74.474.5 ASMs/g in 20112012 to 78.679.7 ASMs/g in 20152016. These improvements have not only reduced our fuel consumption rate, but also the amount of greenhouse gases and other pollutants that our operationsaircraft emit.

COMPETITION

Competition in the airline industry is intense and unpredictable. Our competitors consist primarily of other airlines and, to a lesser extent, other forms of transportation. Competition can be direct, in the form of another carrier flying the exact non-stop route, or indirect, where a carrier serves the same two cities non-stop from an alternative airport in that city or via an itinerary requiring a connection at another airport. We compete with other domestic airlines and a limited number of international airlines on nearly all of our scheduled routes. Our largest competitor is Delta, Air Lines, who has significantly increased their capacity in Seattle over the past twofew years. Approximately 60%61% of our capacity to and from Seattle competes with Delta. Based on schedules filed with the U.S. Department of Transportation, we expect the amount of competitive capacity overlap with all carriers to increase by more than 13%5% in the first half of 2016,2017, weighted based on our network.

We believe that the following principal competitive factors are important to our customers:guests:
 
Safety record
 
Customer service and reputation

We compete with other airlines in areas of customer service such as on-time performance, passenger amenities - guest amenities—including first class and other premium seating, quality of on-board products, aircraft type and comfort. In 2015,2016, Alaska Airlines ranked “Highesthighest in Customer Satisfactioncustomer satisfaction among Traditional Network Carriers”traditional network carriers by J.D. Power and Associates for the eighthninth year in a row. All of our 2015 mainline aircraft deliveries included the Boeing Sky Interior, our Alaska Beyond™ in-flight experience, which features our streaming in-flight entertainment, gourmet food designed by Tom Douglas, and comfortable seats with additional space and power as part of our exceptional, above and beyond flight experience. In 2015, we introduced Preferred Plus seating and Boeing's new Space BinsTM. Preferred Plus gives customers the option to upgrade to bulkhead and exit row seats at check-in for a nominal fee and includes early boarding and a free cocktail. Space BinsTM provide space for up to 50% more carry-on bags on board our aircraft, providing a more hassle-free boarding experience for our passengers. In 2016 we will bebegan installing Boeing Space Bins on our Boeing 737-900ER fleet, providing additional overhead bin space for our guests. In 2017, we are launching a Premium Class of service on our airplanesB737 aircraft that will provide extra legroom, early boarding, premium snacks and a complimentary alcoholic beverages.beverage. Additionally, in 2017 we are increasing the distance between seats in our first class cabins on the Alaska B737-900 and B737-900ER fleet, providing significantly more space for guests flying in the first class cabin. We expect to fully complete the first class cabin upgrades on the B737-900 and B737-900ER fleet in early 2018.



Cabins of our Virgin America Airbus A320 family fleet have a distinctive appearance through innovative design and use of technology. Every cabin features special mood lighting, designed to create a calming, low-stress environment for our guests; custom leather seats, tailored to provide comfort, especially on our long-haul flights; inflight wireless internet access; and electrical power outlets adjacent to every seat. All of our guests flying on Virgin America aircraft have access to the Red® inflight entertainment system that allows each guest to customize his or her inflight experience through a host of entertainment options, on-demand food and beverage ordering system and a seat-to-seat chat function.

Our employees are a key element of our product. We have a highly engaged workforce that strives to provide a high degree of service and hospitality to our guests both at the airport and in flight. We heavily emphasize our service standards with our employees through training and education programs and monetary incentives related to operational performance and guest surveys.
Fares and ancillary services

The pricing of fares is a significant competitive factor in the airline industry, and the increased availability of fare information on the Internet allows travelers to easily compare fares and identify competitor promotions and discounts. Pricing is driven by a variety of factors including, but not limited to, market-specific capacity, market share per route/geographic area, cost structure, fare vs. ancillary revenue strategies, and demand.

For example, airlines often discount fares to drive traffic in new markets or to stimulate traffic when necessary to improve load factors. In addition, traditional network carriers have been able to reduce their operating costs through bankruptcies and mergers, while low-cost carriers have continued to grow 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 one mile), which in turn may enable them to lower their fares. These factors can reduce our pricing power and that of the airline industry as a whole.

Domestic airline capacity is dominated by four large carriers, representing approximately 85%82% of total seats. Accordingly, if these carriers discount their fares or enter into our core markets, we must match those fares in order to maintain our load factors, often resulting in year-over-year decreases in our yields. We will defend our core markets vigorously and, if necessary, redeploy capacity to better match supply with demand. We believe the restructuring we've completed over the past decade has decreased our costs, enabling us to offer competitive fares while still earning appropriate returns for our shareholders.

Routes served, flight schedules, codesharing and interline relationships, and frequent flierflyer programs

We also compete with other airlines based on markets served, the frequency of service to those markets and frequent flierflyer opportunities. Some airlines have more extensive route structures than we do, and they offer significantly more international routes. In order to expand opportunities for our customers,guests, we enter into codesharing and interline relationships with other airlines that provide reciprocal frequent flierflyer mileage credit and redemption privileges. These relationships allow us to offer our customersguests access to more destinations than we can on our own, gain exposure in markets we don't serve and allow our customersguests more opportunities to earn and redeem frequent flierflyer miles. Our Mileage Plan™ offers onefrequent flyer programs offer some of the most comprehensive benefits to our members with the ability to earn and redeem miles on 1624 of our partner carriers.

In addition to domestic or foreign airlines that we compete with on most of our routes, we compete with ground transportation in our short-haul markets.  Both carriers,Our airlines, to some extent, also compete with technology such as video conferencing and internet-based meeting tools that have changed the need for, or frequency, of face-to-face business meetings.

TICKET DISTRIBUTION
 
Our tickets are distributed through three primary channels:
 
Alaskaair.com: Direct to customer:It is less expensive for us to sell through thisour direct channelchannels at alaskaair.com and asvirginamerica.com. As a result, we continue to take steps to drive more business to our website.websites. In addition, we believe this channel is preferable from a branding and customer-relationship standpoint in that we can establish ongoing communication with the customer and tailor offers accordingly.
 
Traditional and online travel agencies:Both traditional and online travel agencies typically use Global Distribution Systems (GDS) to obtain their fare and inventory data from airlines. Bookings made through these agencies result in a fee that is charged to the airline. Many of our large corporate customers require us to use these agencies. Some of our competitors do not use this distribution channel and, as a result, have lower ticket distribution costs.


 
Reservation call centers:These The Alaska call centers are located in Phoenix, AZ, Kent, WA, and Boise, ID. Virgin America uses an outsourced call center. We generally charge a $15 fee for booking reservations through thesethe Alaska call centers and $20 for booking reservations through the Virgin America call centers. We plan on combining the reservations call centers over the next several months as part of our integration efforts.

Includes results for Virgin America for the period December 14, 2016 through December 31, 2016.

SEASONALITY AND OTHER FACTORS

Our results of operations for any interim period are not necessarily indicative of those for the entire year because our business is subject to seasonal fluctuations. Our profitability is generally lowest during the first and fourth quarters due principally to fewer departures and passengers. Profitability typically increases in the second quarter and then reaches its highest level during the third quarter as a result of vacation travel, including increased activity in the state of Alaska. However, we have taken steps over the past few years to better managesignificantly improved the seasonality of our operations by adding flightsour continued growth from the West Coast to leisure destinations, like Hawaii and Costa Rica, and expanding to citiesleisure and business destinations in the mid-continental and eastern U.S.

In addition to passenger loads, factors that could cause our quarterly operating results to vary include:  

general economic conditions and resulting changes in passenger demand,

•      changes in fuel costs,
 
pricing initiatives by us or our competitors,
 
increases in competition at our primary airports, and
 
increases or decreases in passenger and volume-driven variable costs.
 
Many of the markets we serve experience inclement weather conditions in the winter, causing increased costs associated with deicing aircraft, canceling flights and accommodating displaced passengers. Due to our geographic area of operations, we can be more susceptible to adverse weather conditions, particularly in the state of Alaska and the Pacific Northwest, than some of our competitors, who may be better able to spread weather-related risks over larger route systems. We also are more susceptible to ground delays due to our heavy concentration of departures from San Francisco International Airport.

No material part of our business or that of our subsidiaries is dependent upon a single customer, or upon a few high-volume customers.

EMPLOYEES

Our business is labor intensive. As of December 31, 2015,2016, we employed 15,143 (11,61419,112 (12,224 at Alaska, 3,252 at Virgin America and 3,5293,636 at Horizon) active full-time and part-time employees. Wages and benefits, including variable incentive pay, represented approximately 41%40% of our total non-fuel operating expenses in both 20152016 and 20142015.

Most major airlines, including ours,Alaska and Horizon, have employee groups that are covered by collective bargaining agreements. Airlines with unionized work forces generally have higher labor costs than carriers without unionized work forces, and they may not have the ability to adjust labor costs downward quickly enough to respond to new competition or slowing demand. At December 31, 20152016, labor unions represented 83%84% of Alaska’s and 44%43% of Horizon’s employees. Inflight teammates, our term for flight attendants at Virgin America, and pilots at Virgin America voted to be represented by unions on


August 13, 2014 and June 4, 2015, respectively. However, as of December 31, 2016 neither Virgin America work group had completed collective bargaining agreement negotiations.

Our relations with U.S. labor organizations are governed by the Railway Labor Act (RLA)("RLA"). Under this act, collective bargaining agreements do not expire but instead become amendable as of a stated date. If either party wishes to modify the terms of any such agreement, it must notify the other party in the manner prescribed by the RLA and/or described in the agreement. After receipt of such notice, the parties must meet for direct negotiations, and if no agreement is reached, either party may request the National Mediation Board (NMB)("NMB") to initiate a process including mediation, arbitration, and a potential “cooling off” period that must be followed before either party may engage in self-help.

REGULATION
 
GENERAL
 
The airline industry is highly regulated, most notably by the federal government. The Department of Transportation (DOT), the Federal Aviation Administration (FAA) and the Transportation Security Administration (TSA) exercise significant regulatory authority over air carriers.
 
DOT: In order to provide passenger and cargo air transportation in the U.S., a domestic airline is required to hold a certificate of public convenience and necessity issued by the DOT. Subject to certain individual airport capacity, noise and other restrictions, this certificate permits an air carrier to operate between any two points in the U.S. Certificates do not expire, but may be revoked for failure to comply with federal aviation statutes, regulations, orders or the terms of the certificates. While airlines are permitted to establish their own fares without governmentalgovernment regulation, the DOT has jurisdiction over the approval of international codeshare agreements, marketing alliance agreements between major domestic carriers, international and some domestic route authorities, Essential Air Service market subsidies, carrier liability for personal or property damage, and certain airport rates and charges disputes. International treaties may also contain restrictions or requirements for flying outside of the U.S. and impose different carrier liability limits than those applicable to domestic flights. The DOT has been active in implementing a variety of “consumer protection” regulations, covering subjects such as advertising, passenger communications, denied boarding compensation and tarmac delay response. Airlines are subject to enforcement actions that are brought by the DOT from time to time for alleged violations of consumer protection and other economic regulations. We are not aware of any enforcement proceedings that could either materially affect our financial position or impact our authority to operate.

FAA:The FAA, through Federal Aviation Regulations (FARs), generally regulates all aspects of airline operations, including establishing personnel, maintenance and flight operation standards. Domestic airlines are required to hold a valid air carrier operating certificate issued by the FAA. Pursuant to these regulations, we have established, and the FAA has approved, our operations specifications and a maintenance program for each type of aircraft we operate. TheEach maintenance program provides for the ongoing maintenance of suchthe relevant aircraft type, ranging from frequent routine inspections to major overhauls. From time to time the FAA issues airworthiness directives (ADs) that must be incorporated into our aircraft maintenance program and operations. All airlines are subject to enforcement actions that are brought by the FAA from time to time for alleged violations of FARs or ADs. At this time, we are not aware of any enforcement proceedings that could either materially affect our financial position or impact our authority to operate.

TSA:Airlines serving the U.S. must operate a TSA-approved Aircraft Operator Standard Security Program (AOSSP), and comply with TSA Security Directives (SDs) and regulations. Under TSA authority, we are required to collect a September 11 Security Fee of $5.60 per one-way trip from passengers and remit that sum to the government to fund aviation security measures. Airlines are subject to enforcement actions that are brought by the TSA from time to time for alleged violations of the AOSSP, SDs or security regulations. We are not aware of any enforcement proceedings that could either materially affect our financial position or impact our authority to operate. Under TSA authority, we are required to collect a September 11 Security Fee of $5.60 per one-way trip from passengers and remit that sum to the government to fund aviation security measures.

The Department of Justice and DOT have jurisdiction over airline antitrust matters. The U.S. Postal Service has jurisdiction over certain aspects of the transportation of mail and related services. Labor relations in the air transportation industry are regulated under the Railway Labor Act. To the extent we continue to fly to foreign countries and pursue alliances with international carriers, we may be subject to certain regulations of foreign agencies and international treaties.



ENVIRONMENTAL AND OCCUPATIONAL SAFETY MATTERS
 
We are subject to various laws and government regulations concerning environmental matters and employee safety and health in the U.S. and other countries. U.S. federal laws that have a particular effect on us include the Airport Noise and Capacity Act of 1990, 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, Superfund Amendments and Reauthorization Act, and the Oil Pollution Control Act. We are also subject to the oversight of the Occupational Safety and Health Administration (OSHA) concerning employee safety and health matters. The U.S. Environmental Protection Agency, OSHA, and other federal agencies have been authorized to create and enforce regulations that have an impact on our operations. In addition to these federal activities, various states have been delegated certain authorities under these federal statutes. Many state and local governments have adopted environmental and employee safety and health laws and regulations. We maintain our safety, health and environmental programs in order to meet or exceed these requirements.

We expectbelieve there willmay be local or federal legislation in the future to reduce carbon and other greenhouse gas emissions. Alaska and HorizonOver the course of several years, we have transitioned to more fuel-efficient aircraft fleets.fleets and reduced our emissions with the goal of continuing that trend.

The Airport Noise and Capacity Act recognizes the rights of airport operators with noise problems to implement local noise abatement programs so long as they do not interfere unreasonably with interstate or foreign commerce or the national air transportation system. Authorities in several cities have established aircraft noise reduction programs, including the imposition of nighttime curfews. We believe we have sufficient scheduling flexibility to accommodate local noise restrictions.
 
Although we do not currently anticipate that these regulatory matters, individually or collectively, will have a material effect on our financial condition, results of operations or cash flows, new regulations or compliance issues that we do not currently anticipate could have the potential to harm our financial condition, results of operations or cash flows in future periods.

INSURANCE

We carry insurance of types customary in the airline industry and in amounts deemed adequate to protect our interests and property and to comply both with federal regulations and certain credit and lease agreements. The insurance policies principally provide coverage for Airline Hull, Spares and Comprehensive Legal Liability Insurance, War and Allied Perils, and Workers’ Compensation. In addition, we currently carry a Cyber Liability policy in the event of security breaches from malicious parties.

We believe that our emphasis on safety and our state-of-the-art flight deck safety technology help to control the cost of our insurance.

ITEM 1A. RISK FACTORS
 
If any of the following occurs, our business, financial condition and results of operations could suffer. In such case, the trading price of our common stock could also decline. We operate in a continually changing business environment.  In this environment, new risks may emerge, and already identified risks may vary significantly in terms of impact and likelihood of occurrence. Management cannot predict such developments, nor can it assess the impact, if any, on our business of such new risk factors or of events described in any forward-looking statements.

We have adopted an enterprise wide Risk Analysis and Oversight Program designed to identify the various risks faced by the organization, assign responsibility for managing those risks to individual executives as well as align these risks with Board oversight. These enterprise-level identified risks have been aligned to the risk factors discussed below.

SAFETY, COMPLIANCE AND OPERATIONAL EXCELLENCE

Our reputation and financial results could be harmed in the event of an airline accident or incident.
 
An accident or incident involving one of our aircraft or an aircraft operated by one of our codeshare partners or CPA carriers could involve a significant loss of life and result in a loss of confidence in our airlines by the flying public and/or aviation authorities. We could experience significant claims from injured passengers, by-standersbystanders and surviving relatives as well as costs for the repair or replacement of a damaged aircraft and its consequential temporary or permanent loss from service. We maintain liability insurance in amounts and of the type generally consistent with industry practice, as do our codeshare partners and CPA carriers. However, the amount of such coverage may not be adequate to fully cover all claims, and we may be forced to bear substantial economic losses from an accident.such event. Substantial claims resulting from an accident in excess of our related insurance coverage would harm our business and financial results. Moreover, any aircraft accident or incident, even if it is fully insured and even if it does not involve one of our aircraft, could cause a public perception that our airlines or the aircraft we or our partners fly are less safe or reliable than other transportation alternatives, whichalternatives. This would harm our business.



Our operations are often affected by factors beyond our control, including delays, cancellations and other conditions, which could harm our business, financial condition and results of operations.

Like otherAs is the case for all airlines, our operations often are affected by delays, cancellations and other conditions caused by factors largely beyond our control.

Other conditionsFactors that might impact our operations include:

lack of operational approval (e.g. new routes, aircraft deliveries, etc.);

congestion and/or space constraints at airports or air traffic control problems;

lack of operational approval (e.g. new routes, aircraft deliveries, etc.);

adverse weather conditions;
 
increased security measures or breaches in security;

contagious illness and fear of contagion;
 
changes in international treaties concerning air rights;

international or domestic conflicts or terrorist activity; and

other changes in business conditions.

Due to our concentration of flights in the Pacific Northwest and Alaska, we believe a large portion of our operation is more susceptible to adverse weather conditions. A general reduction in airline passenger traffic as a result of any of the above-mentioned factors could harm our business, financial condition and results of operations.


12




Changes in government regulation imposing additional requirements and restrictions on our operations could increase our operating costs and result in service delays and disruptions.
 
Airlines are subject to extensive regulatory and legal requirements, both domestically and internationally, that involve significant compliance costs. In the last several years, Congress has passed laws, and the U.S. DOT, the TSA and the FAA have issued regulations that have required significant expenditures relating to the maintenance andof aircraft, operation of airlines and establishment of consumer protections.protection.

Similarly, there are a number of legislative and regulatory initiatives and reforms at the federal, state and local level, includinglevels. These initiatives include increasingly stringent laws protectingto protect the environment, minimum wage requirements and health care mandates thatmandates. They could affect our relationship with our workforce and the vendors that serve our airlines and cause our expenses to increase without an ability to pass through these costs. 

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. Many airports have increased their rates and charges to air carriers related to reflect higher costs of security, costs, increased costs relatedupdates to updated infrastructures and other costs.other. Additional laws, regulations, taxes, and airport rates and airport charges have beenmay be occasionally proposed from time to time that could significantly increase the cost of airline operations or reduce the demand for air travel. Although lawmakers may impose these additional fees and view them as “pass-through” costs, we believe that a higher total ticket price will influence consumer purchase and travel decisions and may result in an overall decline in passenger traffic, which would harm our business.

The airline industry continues to face potential security concerns and related costs.

Terrorist attacks, the fear of such attacks or other hostilities involving the U.S. could have a significant negative effect on the airline industry, including us, and could:
 
significantly reduce passenger traffic and yields as a result of a potentially dramatic drop in demand for air travel;
 
significantly increase security and insurance costs;
 


make war risk or other insurance unavailable or extremely expensive;
 
increase fuel costs and the volatility of fuel prices;
 
increase costs from airport shutdowns, flight cancellations and delays resulting from security breaches and perceived safety threats; and
 
result in a grounding of commercial air traffic by the FAA.
 
The occurrence of any of these events would harm our business, financial condition and results of operations.
 
We rely on third-party vendors for certain critical activities.
 
We have historically reliedrely on outside vendors for a variety of services and functions critical to our business, including airframe and engine maintenance, ground handling, fueling, computer reservation system hosting, telecommunication systems and information technology infrastructure and services. As part of our cost-reduction efforts, our reliance on outside vendors has increased and may continue to do so in the future, especially since we rely on timely and effective third-party performance in conjunction with many of our technology-related initiatives.
 
Even though we strive to formalize agreements with these vendors that define expected service levels, our use of outside vendors increases our exposure to several risks. In the event that one or more vendors go into bankruptcy, ceases operation or fails to perform as promised, replacement services may not be readily available at competitive rates, or at all. If one of our vendors fails to perform adequately, we may experience increased costs, delays, maintenance issues, safety issues or negative public perception of our airline. Vendor bankruptcies, unionization, regulatory compliance issues or significant changes in the competitive marketplace among suppliers could adversely affect vendor services or force us to renegotiate existing agreements on less favorable terms. These events could result in disruptions in our operations or increases in our cost structure.

STRATEGY

The airline industry is highly competitive and susceptible to price discounting and changes in capacity, which could have a material adverse effect on the Company.our business. If we cannot successfully compete in the marketplace, our business, financial condition and operating results will be materially adversely affected.

The U.S. airline industry is characterized by substantial price competition. In recent years, the market share held by low-cost carriers and so-called ultra low-cost carriers has increased significantly and is expected to continue to increase. Airlines also compete for market share by increasing or decreasing their capacity, including route systems and the number of markets served. Several of our competitors have increased their capacity in markets we serve, particularly on the West Coast and in our Seattle hub, therefore increasingresulting in increased competition for those destinations. This increasedIncreased competition in both domestic and international markets may have a material adverse effect on the Company’sour results of operations, financial condition or liquidity.

We continue to strive toward aggressive cost-reduction goals that are an important part of our business strategy of offering the best value to passengersour guests through competitive fares while achieving acceptable profit margins and return on capital. If we are unable to reduce our costs over the long-term and achieve sustained targeted returns on invested capital, we will likely not be able to grow our business in the future or weather industry downturns and thereforedownturns. Therefore, our financial results may suffer.

The airline industry may undergo further restructuring, consolidation, or the creation or modification of alliances or joint ventures, any of which could have a material adverse effect on our business, financial condition and results of operations.

We continue to face strong competition from other carriers due to restructuring, consolidation, and the creation and modification of alliances and joint ventures. Since deregulation, both the U.S. and international airline industries have experienced consolidation through a number of mergers and acquisitions. Carriers may also improve their competitive positions through airline alliances, slot swaps/acquisitions and/or joint ventures. Certain airline joint ventures further competition by allowing airlines to coordinate routes, pool revenues and costs, and enjoy other mutual benefits, achieving many of the benefits of consolidation.

We depend on a few key markets to be successful.
 
Our strategy is to focusincludes being the premier carrier for people living on servingthe West Coast. This results in a fewhigh concentration of our business in key markets, including Seattle, Los Angeles, Anchorage, Portland, and Hawaii .West Coast markets. A significant portion of our flights occur to and from our Seattle hub. In 20152016, passengers to and from Seattle accounted for 61% of our total passengers.guests. We expect this to become more diversified in the future as a result of the recent acquisition of Virgin America, whose primary hubs are San Francisco and Los Angeles.



We believe that concentrating our service offerings in this way allows us to maximize our investment in personnel, aircraft and ground facilities, as well as to gain greater advantage from sales and marketing efforts in those regions. As a result, we remain highly dependent on our key markets. Our business could be harmed by any circumstances causing a reduction in demand for air transportation in our key markets. An increase in competition in our key markets could also cause us to reduce fares or take other competitive measures that, if sustained, could harm our business, financial condition and results of operations.

Economic uncertainty or another recession would likely impact demand for our product and could harm our financial condition and results of operations.
 
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. We are also highly dependent on U.S. consumer confidence and the health of the U.S. economy. Unfavorable U.S. economic conditions have historically 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 shorthaulshorter distance travelers, in particular, have the option to replace air travel with surface travel. Businesses are able to forgo air travel by using communication alternatives such as videoconferencing 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 also hamper the ability of airlines to raise fares to counteract increased fuel, labor and other costs. Unfavorable or even uncertain economic conditions could negatively affect our financial condition and results of operations.


14




We are dependent on a limited number of suppliers for aircraft and parts.
 
Alaska is dependent on Boeing as its sole supplier for aircraft and many aircraft parts. HorizonVirgin America is similarly dependent on Bombardier.Airbus, and Horizon is dependent on Bombardier and soon Embraer. Additionally, each carrier is dependent on sole suppliers for aircraft engines.engines for each aircraft type. As a result, we are more vulnerable to any problemsissues associated with the supply of those aircraft and parts, including design defects, mechanical problems, contractual performance by the manufacturers or adverse perception by the public that would result in customer avoidance or in actions by the FAA resulting in an inability to operate our aircraft.aircraft or instability in the foreign countries, in which the aircraft and its parts are manufactured.

We rely on partner airlines for codeshare and frequent flierflyer marketing arrangements.
 
Alaska and HorizonOur airlines are parties to marketing agreements with a number of domestic and international air carriers, or “partners,“partners." including, but not limited to, American Airlines and Delta Air Lines. These agreements provide that certain flight segments operated by us are held out as partner “codeshare” flights and that certain partner flights are held out for sale as Alaska or Virgin America codeshare flights. In addition, the agreements generally provide that members of Alaska’s Mileage Plan™ program, or Virgin America's Elevate® program, can earn milescredit on or redeem milescredit for partner flights and vice versa. We receive revenue from flights sold under codeshare and from interline arrangements. In addition, we believe that the frequent flierflyer arrangements are an important part of our Mileage Plan™ program.frequent flyer programs. The loss of a significant partner through bankruptcy, consolidation, or otherwise, could have a negative effect on our revenues or the attractiveness of our Mileage Plan™, and Elevate® programs, which we believe is a source of competitive advantage.

There is ongoing speculation that further airline consolidation or reorganization could occur in the future. We routinely engage in analysis and discussions regarding our own strategic position, including alliances, codeshare arrangements, interline arrangements and frequent flierflyer program enhancements, and may have future discussions with other airlines regarding similar activities. If other airlines participate in consolidation or reorganization, those airlines may significantly improve their cost structures or revenue generation capabilities, thereby potentially making them stronger competitors of ours and potentially impairing our ability to realize expected benefits from our own strategic relationships.



INFORMATION TECHNOLOGY

We rely heavily on automated systems to operate our business, and a failure to invest in new technology or a disruption of our current systems or their operators could harm our business.
 
We depend on automated systems to operate our business, including our airline reservation system, our telecommunication systems, our website, our maintenance systems, our check-in kiosks, mobile devices and other systems. Substantially all of our tickets are issued to passengersour guests as electronic tickets, and the majority of our customers check in using our website, airport kiosks, or our airport kiosks.mobile application. We depend on our reservation system to be able to issue, track and accept these electronic tickets. In order for our operations to work efficiently, we must continue to invest in new technology to ensure that our website, reservation system and check-in systems are able to accommodate a high volume of traffic, maintain secure information security and deliver important flight information. Substantial or repeated website, reservations system or telecommunication systems failures or service disruptions could reduce the attractiveness of our services and cause our customersguests to do business with another airline. In addition, we rely on other automated systems for crew scheduling, flight dispatch and other operational needs. In 2016,2017, subsequent to year end, we expect to migratemigrated to a new crew management system. We also plan to move our primary data center location. Disruptions, failed migration, untimely recovery, or a breach of these systems or the data center could result in the loss of important data, an increase of our expenses, an impact on our operational performance or a possible temporary cessation of our operations.

If we do not maintain the privacy and security of our information, we could damage our reputation and incur substantial legal and regulatory costs.

We accept, store and transmit information about our customers,guests, our employees, our business partners and our business.  In addition, we frequently rely on third-party hosting sites and data processors, including cloud providers. Our sensitive information relies on secure transmission over public and private networks.  A compromise of our systems, the security of our infrastructure or those of other business partners that result in our information being accessed or stolen by unauthorized persons could adversely affect our operations and our reputation.

FINANCIAL CONDITION AND FINANCIAL MARKETS

Our business, financial condition and results of operations are substantially exposed to the volatility of jet fuel prices. Significant increases in jet fuel costs would harm our business.
 
Fuel costs constitute a significant portion of our total operating expensesexpenses. Future increases in the price of jet fuel may harm our business, financial condition and results of operations unless we are able to increase fares and fees or add additional ancillary services to attempt to recover increasing fuel costs.

Our indebtedness and other fixed obligations could increase the volatility of earnings and otherwise restrict our activities and potentially lead to liquidity constraints.

We incurred a significant amount of new debt to finance our acquisition of Virgin America. We now have and will continue to have for the foreseeable future a substantial amount of debt. Due to our high fixed costs, including aircraft lease commitments and debt service, a decrease in revenues would result in a disproportionately greater decrease in earnings.

Our outstanding long-term debt and other fixed obligations could have important consequences. For example, they could limit our ability to obtain additional financing to fund our future capital expenditures, acquisitions, working capital or other purposes; require us to dedicate a material portion of our operating cash flow to fund lease payments and interest payments on indebtedness, thereby reducing funds available for other purposes; or limit our ability to withstand competitive pressures and reduce our flexibility in responding to changing business and economic conditions.

Although we have historically been able to generate sufficient cash flow from our operations to pay our debt and other fixed obligations when they become due, we cannot ensure we will be able to do so in the future. If we fail to do so, our business could be harmed.

See "Liquidity and Capital Resources" within Item 7 of this filing for more detailed information about our obligations and commitments.



Certain of the Company’sour financing agreements have covenants that impose operating and financial restrictions on the Company and its subsidiaries.us.

Certain of our credit facilities and indentures governing our secured borrowings impose certain operating and financial covenants on us. Such covenants require us to maintain, depending on the particular agreement, minimum liquidity and/or minimum collateral coverage ratios and other negative covenants customary for such financings. A decline in the value of collateral could result in a situation where we may not be able to maintain the required collateral coverage ratio.

Our ability to comply with these covenants may be affected by events beyond our control, including the overall industry revenue environment and the level of fuel costs, and we may be required to seek waivers or amendments of covenants, repay all or a portion of the debt or find alternative sources of financing.

Our maintenance costs will increase as our fleet ages, and we will periodically incur substantial maintenance costs due to the maintenance schedules of our aircraft fleet.

As of December 31, 2015,2016, the average age of our NextGen aircraft (B737-800, -900, -900ERs) was approximately 6.47.3 years, and the average age of our Q400 aircraft was approximately 910 years, and the average age of our A319 and A320 aircraft was approximately 6.8 years. Our relatively new aircraft currently require less maintenance now than they will in the future. Any significant increase in maintenance expenses could have a material adverse effect on our results of operations.

BRAND AND REPUTATION

As we evolve our brand to appeal to a changing demographic and grow into new markets, we will engage in strategic initiatives that may not be favorably received by all customers.our guests.
 
We continue to focus on strategic initiatives designed to increase our brand appeal to a diverse and evolving demographic of airline travelers. These efforts could include significant improvementsenhancements to our in-airport and on-board environments, increasing our direct customer relationships through improvements to our purchasing portals (digital and mobile), and optimization of our customer loyalty programs.

In pursuit of these efforts we may negatively affect our reputation with some of our existing customer base.
 
LABOR RELATIONS AND LABOR STRATEGY

A significant increase in labor costs, unsuccessful attempts to strengthen our relationships with union employees or loss of key personnel could adversely affect our business and results of operations.
  
Labor costs are a significant component of our total expenses. Each of ourAlaska and Horizon's represented employee groups has a separate collective bargaining agreement, andagreement. Through negotiations or transition agreements in the Virgin America integration, each group could make demands that would increase our operating expenses and adversely affect our financial performance if we agree to them. The same result could apply if we experience a significant increase in vendor labor costs, including wage rate increases, thatwhich could ultimately flow through to us.us under the applicable services agreement.

As of December 31, 20152016, labor unions represented approximately 83%84% of Alaska’s and 44%43% of Horizon’s employees. Although Virgin America employees are not currently covered under collective bargaining agreements, pilots and inflight teammates have elected to be represented and will, through negotiations, ultimately enter into joint collective bargaining agreements with Alaska's represented workforce. Although we have been successful in maturingfostering communications, negotiating approaches and developing other strategies to enhance workforce engagement in the Company'sour long-term vision, future uncertainty around open contractsincluding the joint collective bargaining negotiations for the integration of Alaska's and Virgin America's represented work groupscould be a distraction, affecting employee focus inon our business and diverting management’s attention from other projects and issues.

We compete against the major U.S. airlines and other businesses for labor in many highly skilled positions. If we are unable to hire, train and retain qualified employees at a reasonable cost, sustain employee engagement in the Company'sour strategic vision,

or if we are unsuccessful at implementing succession plans for our key staff, we may be unable to grow or sustain our business. In recent years, there have been pilot shortages in hiring in the regional market.market, and there is an anticipated pilot shortage in hiring in the mainline markets in the next two to three years. Attrition beyond normal levels could negatively impact our operating results, and our business prospects could be harmed.



Employees could also engage in job actions such as slow-downs, work-to-rule campaigns, sick-outs or other actions designed to disrupt our normal operations in an attempt to pressure us to acquiesce to wage or other demands during Section 6 negotiations or transition agreement discussions. Although the Railway Labor Act makes such “self-help” unlawful until the National Mediation Board releases the parties following lengthy mediation attempts, and we could seek injunctive relief or other remedies against premature self-help, such actions could cause significant harm even if we were ultimately to be successful.

ACQUISITION AND INTEGRATION OF VIRGIN AMERICA

We may be unable to effectively integrate Virgin America’s business and realize the anticipated benefits of the acquisition. In addition, delays in integration could cause anticipated synergies to take longer to realize than currently anticipated.

We must devote significant management attention and resources to integrating the business practices and operations of Virgin America. Potential difficulties we may encounter as part of the integration process include the following:

the inability to successfully combine the Virgin America business with that of Alaska's in a manner that permits us to achieve anticipated net synergies and other anticipated benefits of the acquisition;

the inability to successfully attract and retain Virgin America guests upon integration with Alaska;

the challenges associated with operating aircraft types new to our operations, specifically the Airbus A319 and A320;

the challenges associated with an expanded or new presence in more congested airports and markets;

the challenges associated with integrating complex systems, technology, aircraft fleets, networks, facilities and other assets in a seamless manner that minimizes any adverse impact on guests, suppliers, employees and other constituents;

the challenges associated with integrating Virgin America employees into Alaska's workforce while maintaining our focus on providing consistent, high quality customer service, including seniority list integration, negotiation of transition process agreements and, in the case of the pilot workgroups, negotiation of a joint collective bargaining agreement; and

potential unknown liabilities, liabilities that are significantly larger than we currently anticipate, and unforeseen increased expenses or delays, including costs to integrate Virgin America’s business that may exceed our current estimates.

Any of the foregoing factors could adversely affect our ability to maintain relationships with guests, suppliers, employees and other constituencies or our ability to achieve the anticipated benefits of the acquisition on a timely basis, or at all. These factors could also reduce our earnings or otherwise adversely affect our business and financial results. In addition, integration requirements have caused, and may continue to cause, a delay of other strategic initiatives.

The Virgin brand is not under our control, and negative publicity related to the Virgin brand name could materially adversely affect our business.

Virgin America licenses rights to the Virgin brand from certain entities affiliated with the Virgin Group on a non-exclusive basis. The Virgin brand is also licensed to and used by a number of other companies, including two airlines, Virgin Atlantic Airways and Virgin Australia Airlines, operating in other geographies. We rely on the general goodwill of consumers and our employees towards the Virgin brand. Consequently, any adverse publicity in relation to the Virgin brand name, its principals, particularly Sir Richard Branson who is closely associated with the brand, or another Virgin-branded company over which we have no control or influence could have a material adverse effect on our business.

We obtain our rights to use the Virgin brand under agreements with certain entities affiliated with the Virgin Group, and we would lose those rights if these agreements are terminated or not renewed.

Virgin America is a party to license agreements with certain entities affiliated with the Virgin Group pursuant to which we obtain rights to use the Virgin brand. The licensor may terminate the agreements upon the occurrence of a number of specified events including if Virgin America commits a material breach of our obligations under the agreements that is uncured for more than 10 business days or if we materially damage the Virgin brand. If we lose our rights to use the Virgin brand, we would lose the goodwill associated with the brand name, which would likely require substantial expenditures, and our business and financial condition would likely be materially adversely affected.



The need to integrate Virgin America’s workforce into joint collective bargaining agreements with Alaska's workforce presents the potential for delay in achieving expected synergies and other benefits or labor disputes that could adversely affect our operations and costs.

The successful integration of Virgin America and achievement of the anticipated benefits of the acquisition depend significantly on integrating Virgin America’s employees into Alaska and on maintaining productive employee relations. Failure to do so presents the potential for delays in achieving expected synergies and other benefits of integration or labor disputes that could adversely affect our operations and costs. The process for integrating labor groups in an airline merger is governed by a combination of the Railway Labor Act, the McCaskill-Bond Act, and where applicable, the existing provisions of our collective bargaining agreements (“CBAs”) and internal union policies.

Under the Railway Labor Act, the National Mediation Board has exclusive authority to resolve representation disputes arising out of airline mergers. The disputes that the National Mediation Board has authority to resolve include (i) whether the carriers, through the merger, have integrated operations to the point of creating a “single transportation system” for representation purposes; (ii) determination of the appropriate “craft or class” for representational purposes, including a determination of which positions are to be included within a particular craft or class; and (iii) certification of the system-wide representative organization, if any, for each of our craft or class following the merger. Failure to resolve these disputes could result in delays in achieving expected synergies and other benefits of integration as well as adversely impact our operations and costs.

Pending operational integration of Virgin America with Alaska, it will be necessary to maintain a “fence” between Alaska and Virgin America employee groups that are represented by unions. During this time, we will keep the employee groups separate, each applying the terms of its own existing employment agreements unless other terms have been negotiated. Achievement of expected synergies and other benefits will be delayed until the time that operational integration is obtained.

We are expected to incur substantial expenses related to the acquisition and the integration of Virgin America’s business.

We are expected to incur substantial integration and transition expenses in connection with the acquisition of Virgin America, including the necessary costs associated with integrating the operations of Alaska and Virgin America. There are a large number of processes, policies, procedures, operations, technologies and systems that must be integrated, including reservations, frequent flyer, ticketing/distribution, maintenance and flight operations. While we have assumed that a certain level of expenses will be incurred, there are many factors beyond our control that could affect the total amount or the timing of the integration expenses. Moreover, many of the expenses that will be incurred are, by their nature, difficult to estimate accurately. These expenses could, particularly in the near term, exceed the financial benefits we expect to achieve from the acquisition, including the elimination of duplicative expenses and the realization of economies of scale and cost savings. These integration expenses likely will continue to result in us taking significant charges against earnings in future periods, and the amount and timing of such charges are uncertain at present.

We acquired Virgin America’s indebtedness upon closing of the acquisition, which additional indebtedness may limit our financial and operating flexibility.

Upon closing of the acquisition, we acquired Virgin America’s outstanding indebtedness and became subject to the operating restrictions under the debt instruments governing such indebtedness. Virgin America has significant debt and lease obligations related to existing purchased and leased aircraft. Our increased indebtedness following the acquisition may:

require a substantial portion of cash flows from operations for debt service payments and operating lease payments, thereby reducing the availability of our cash flow to fund working capital, capital expenditures, acquisitions and other general corporate purposes; and

limit our flexibility in planning for, or reacting to, changes in its business and the airline industry and, consequently, negatively affect our competitive position.

We will need to launch certain branding or rebranding initiatives in connection with the acquisition that may take a significant amount of time and involve substantial costs and that may not be favorably received by our guests.

We may incur substantial costs if we decide to rebrand any of Virgin America’s products and services and may not be able to achieve or maintain brand name recognition or status that is comparable to the recognition and status previously enjoyed by Virgin America in any of Virgin America’s markets. The failure of any such rebranding initiatives could adversely affect our ability to attract and retain guests, which could cause us not to realize some or all of the anticipated benefits contemplated to result from the acquisition.



Our ability to use Virgin America’s net operating loss carryforwards to offset future taxable income for U.S. federal and state income tax purposes may be limited as a result of the previous ownership changes, this acquisition or taxable income if it does not reach sufficient levels.

As of the acquisition closing date, Virgin America had federal net operating loss carryforwards (“NOLs”) of approximately $773 million available to offset future taxable income, expiring between 2028 and 2036, and state NOLs of approximately $344 million that expire beginning in 2027 and continuing through 2035.

Virgin America has experienced multiple “ownership changes” as defined in Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), the most recent being its acquisition by us. Section 382 of the Code imposes an annual limitation on the amount of pre-ownership change NOLs of the corporation that experiences ownership change. The limitation imposed by Section 382 of the Code for any post-ownership change year generally would be determined by multiplying the value of such corporation’s stock immediately before the ownership change by the applicable long-term tax-exempt rate. Any unused annual limitation may, subject to certain limits, be carried over to later years, and the limitation may, under certain circumstances, be increased by built-in gains or reduced by built-in losses in the assets held by such corporation at the time of the ownership change. Our use of NOLs generated after the date of an ownership change would not be limited unless we were to experience a subsequent ownership change.

Our ability to use the NOLs will also depend on the amount of taxable income generated in future periods. The NOLs may expire before we can generate sufficient taxable income to utilize the NOLs.

The application of the acquisition method of accounting resulted in us recording a significant amount of goodwill, which could result in significant future impairment charges and negatively affect our financial results.

In accordance with applicable acquisition accounting rules, we recorded goodwill on our consolidated balance sheet to the extent the Virgin America acquisition purchase price exceeded the net fair value of Virgin America’s tangible and identifiable intangible assets and liabilities as of the acquisition date. Goodwill is not amortized, but is tested for impairment at least annually. We could record impairment charges in our results of operations as a result of, among other items, extreme fuel price volatility, a significant decline in the fair value of certain tangible or intangible assets, unfavorable trends in forecasted results of operations and cash flows, uncertain economic environment and other uncertainties. We can provide no assurance that a significant impairment charge will not occur in one or more future periods. Any such charges may materially negatively affect our financial results.

In addition to the CRJ-700s in our operating fleet, we have eight leased CRJ-700s currently subleased to a third party operated for other carriers.

“Management’s Discussion and Analysis of Financial Condition and Results of Operations" discusses future orders and options for additional aircraft.
70 of our owned “Liquidity and Capital Resources" provides more information about aircraft that are used to secure long-term debt arrangements or collateralize our revolving credit facility.  See further discussion in “Liquidity and Capital Resources."facilities.

Alaska’s leased B737 aircraft have lease expiration dates between 20162017 and 2023. Virgin America's leased A319 and A320 aircraft have expiration dates between 2019 and 2025. Horizon’s leased Q400 aircraft have expiration dates in 2018. The leases on the six CRJ-700 aircraft have expiration dates between 2018 and 2020, and the leased E175 aircraft are through our capacity purchase arrangementagreement with SkyWest. Alaska, Virgin America and Horizon have the option to extend mostsome of the leases for additional periods, or the right to purchase the aircraft at the end of the lease term, usually at the then-fair-market value of the aircraft. Air Group also owns two non-operating CRJ-700 aircraft classified as held-for-sale as of December 31, 2016.

GROUND FACILITIES AND SERVICES
 
We own terminal buildings in various cities in the state of Alaska and several buildings located at or near Seattle-Tacoma International Airport (Sea-Tac) near Seattle, WA. These include a multi-bay hangar and shops complex (used primarily for line maintenance), a flight operations and training center, an air cargo facility, an information technology office and datacenter,data center, and various other commercial office buildings.

We lease ticket counters, gates, cargo and baggage space, ground equipment, office space and other support areas at the majority of the airports we serve. Airport leases contain provisions for periodic adjustments of lease rates. We are typically responsible for maintenance, insurance and other facility-related expenses and services under these agreements. We also lease operations, training, data center, and aircraft maintenanceadministrative facilities in Burlingame, CA; Portland, OR; Quincy, WA; and Spokane, WA as well as line maintenance stations in Boise, ID; Bellingham, WA; Eugene, OR; San Jose, CA; Medford, OR; Redmond, OR; Seattle, WA; and Spokane.Spokane, WA. Further, we lease call center facilities in Phoenix, AZ, and Boise.Boise, ID.

ITEM 3.  LEGAL PROCEEDINGS
 
We are a party to routine litigation matters incidental to our business. Management believes the ultimate disposition of these matters is not likely to materially affect our financial position or results of operations. This forward-looking statement is based on management’s current understanding of the relevant law and facts, and it is subject to various contingencies, including the potential costs and risks associated with litigation and the actions of judges and juries.

In 2015, three flight attendants filed a class action lawsuit seeking to represent all Virgin America flight attendants for damages based on alleged violations of California and City of San Francisco wage and hour laws.  Plaintiffs received class certification in November 2016. Virgin America filed a motion for summary judgment seeking to dismiss all claims on various federal preemption grounds.  In January 2017, the Court denied in part and granted in part Virgin America’s motion.  Virgin America believes the claims in this case are without factual and legal merit and intends to defend this lawsuit through, among other


strategies, filing a motion for reconsideration of the Court’s certification decision and denial of summary judgment and, if necessary, a motion for certification of interlocutory appeal to the U.S. Court of Appeals for the Ninth Circuit.

YEAR IN REVIEW

On December 14, 2016 we completed our acquisition of Virgin America, becoming the fifth largest U.S. airline. The Company had a record year incombined company now offers nearly every respect. We1,200 daily flights to 118 destinations across the United States, Mexico, Canada, Costa Rica and Cuba, with more nonstop destinations from the West Coast than any other airline. By combining loyalty programs and networks, along with our award-winning customer service and the expansion of our international partner portfolio, we believe we will provide greater benefits for our guests and become known as the premier airline for people on the West Coast.

In 2016, we posted our 12ththirteenth consecutive annual profit on an adjusted basis, which is a testament to the hard work of our 15,000 employeespeople and the successful execution of our strategic initiatives. Our 2015 consolidated2016 pretax income as reported was a record $1.3$1.3 billion,, a significant an increase of 3% over 2015. Our 2016 pretax income on an adjusted basis (a non-GAAP financial measure) was $1.4 billion, an increase of 8% over 2015. The adjusted pretax income reflects the exclusion of $117 million of merger-related costs associated with our acquisition of Virgin America and $13 million of mark-to-market fuel hedge adjustments.

$975 millionThe improvement in 2014. The $337 million improvementadjusted pretax income was driven by an increase of $230333 million in revenues and a substantial decrease of $464$123 million in our fuel expense. Partially offsetting thesecosts. These benefits waswere partially offset by an increase in operating expenses, excluding fuel and special items, of $296320 million, or 10%, to support the increased capacity of 11%. We recorded $32 millionThis increase reflects the addition of special charges inVirgin America capacity from the current year related to a non-cash pension expense associated with the buyout of the obligation for certain terminated, vested plan participants, and a litigation-related matter.acquisition date through December 31, 2016.

The growth in revenues of $230$333 million was driven by the growth in our business. Webusiness and the inclusion of Virgin America in our results for the period from December 14, 2016 through December 31, 2016. On a combined basis, we launched 2017 new markets in 2015, including 102016 and, in January 2017, we launched historic flights to Havana, Cuba from Los Angeles. On the regional side of our business, we anticipate the delivery of Horizon's Embraer E175 regional jet this spring—the first of an order of 33 placed in early 2016. Our network is rapidly expanding with these regional aircraft and the recent acquisition of Virgin America. We believe we have a strong future ahead of us and look forward to the many new cities such as Charleston, Nashville, Raleigh-Durham, Milwaukee as well as San Jose and Liberia in Costa Rica. We now have over 1,000 departures daily acrossopportunities our network on peak days - a significant milestone forcombined networks will bring our airlines. We are providing more utility than ever before in our primary hub of Seattle, giving our customers substantially more non-stop destinations out of Seattle than any other carrier. The significant decline in fuel expense this year was driven by declines in fuel prices, while the increase in non-fuel operating expenses are primarily growth-related increases as we increased our capacity 11%.company.

Overall, we returned $607$329 million to shareholders during 2015 and2016. We expect to exceed that amountcontinue to return capital to shareholders in 2016.2017, primarily in the form of dividends.

Outlook
 
We completed the acquisition of Virgin America on December 14, 2016, positioning us as the fifth largest airline in the U.S., with an unparalleled ability to serve West Coast travelers. The acquisition of Virgin America provides a platform for growth of our low-fare, premium product, a powerful West Coast network for our guests and enhanced international partnerships. Additionally, Virgin America provides access to constrained gates, particularly on the East Coast, creating increased utility for our guests.



In 2017 and beyond, we are focused on the successful integration of Virgin America with Alaska Air Group, while continuing to work towards obtaining a Single Operating Certificate ("SOC"). We currently expect to receive an SOC in early 2018. Our primary focus every yearpriority throughout the integration process is to run two great airlines and maintain a safe and compliant operation, while providing a great experience for our guests. Additionally, we are particularly focused on merging the cultures and reliable operation atbrands that have made Alaska and Virgin America respected and trusted over the years by our airlines.  guests. We intend to minimize any disruption to our guests during our integration efforts by being transparent about the progress we are making and how the changes may affect them. Employee engagement throughout the integration will remain a top priority as well, ensuring that employees remain engaged, informed and excited about the new Alaska Air Group. We plan to bring our teams together through workshops and trainings delivered throughout 2017. Additionally, we will remain focused on capturing the value and synergies created by combining these two great companies.

In addition to our primary objective, we remain focused on providing a hassle-free experience forintegration with Virgin America, one of our customers, and building a compelling brand to support growingbiggest initiatives is the launch of our network. We recently enhanced our affinity credit card product offering, and in 2016 we are introducing a new premium class of"Premium Class" service on our airplanes. Our refreshed brandB737 aircraft, which provides greater leg room, priority boarding and bold new brand expressions will rollcomplimentary cocktails, among other benefits. Premium Class was rolled out throughoutin early January 2017 and, so far, the results are exceeding our major airportsexpectations in both guest response and on our airplanes in 2016 as well.revenue generation.

Similar to the past several years, we expect to continue our growth plans over the next year. Currently, we expect to grow our combined network capacity in 2017 by approximately 8.5%. The growth rate compares 2017 system-wide capacity by approximately 8% in 2016, compared to 10.6% in 2015. Over the past few years, we have seen competitive capacity increase significantly in our markets, especially in our hometown of Seattle. We expect to see even more competitivewith historical Air Group and Virgin America combined capacity in 2016. This compares to a 10.2% combined growth in 2016 on the same basis. Current schedules indicate competitive capacity will be 13%5 points higher in the first quarter and 14% higher in the second quarter of 2016.2017. We believe that our product, our operation, our engaged employees, andour award-winning service, and our competitive Mileage Plan™ and Elevate® programs, combined with our strong balance sheet, give us the ability to compete vigorously in our markets. Because of our strong financial position, low costs, and high number of unencumbered aircraft, we have an ability to flex our fleet to meet demands and allocate capacity in the markets that meet our return objectives.

With our growth plans and the expectation for lower non-fuel unit costs and steady fuel costs for 2016, we believe our financial performance will continue to be strong.



RESULTS OF OPERATIONS

ADJUSTED (NON-GAAP) RESULTS AND PER-SHARE AMOUNTS

We believe disclosure of earnings excluding the impact of merger-related costs, mark-to-market gains or losses or other individual special revenues or expenses is useful information to investors because:

By eliminating fuel expense and certain special items (including merger-related costs) from our unit metrics, we believe that we have better visibility into the results of operations and our non-fuel cost-reduction initiatives. Our industry is highly competitive and is characterized by high fixed costs, so even a small reduction in non-fuel operating costs can result inlead to a significant improvement in operating results. In addition, we believe that all domestic carriers are similarly impacted by changes in jet fuel costs over the long run, so it is important for management (and thus investors) to understand the impact of (and trends in) company-specific cost drivers, such as labor rates and productivity, airport costs, maintenance costs, etc., which are more controllable by management.

2013 Operating revenue per ASM (RASM) excludes a favorable, one-time, non-cash Special mileage plan revenue item of $192 million primarily related to our modified affinity card agreement with Bank of America, executed in July 2013. In accordance with accounting standards, we recorded this item in the third quarter of 2013, and it reflects a non-cash adjustment of the value of miles outstanding in the program. We believe it is appropriate to exclude this special revenue item from recurring revenues from operations.

Cost per ASM (CASM)("CASM") excluding fuel and certain special items, such as merger-related costs, is one of the most important measures used by management and by the Air Group Board of Directors in assessing quarterly and annual cost performance.

Adjusted income before income tax and CASM excluding fuel (and other items as specified in our plan documents) are important metrics for the employee incentive plan, thatwhich covers allthe majority of Air Group employees.

CASM excluding fuel and certain special items is a measure commonly used by industry analysts and we believe it is the basis by which they compare our airlines to others in the industry. The measure is also the subject of frequent questions from investors.

Disclosure of the individual impact of certain noted items provides investors the ability to measure and monitor performance both with and without these special items. We believe that disclosing the impact of certain items, such as merger-related costs and mark-to-market hedging adjustments, is important because it provides information on significant items that are not necessarily indicative of future performance. Industry analysts and investors consistently measure our performance without these items for better comparability between periods and among other airlines.

Although we disclose our passenger unit revenues, we do not (nor are we able to) evaluate unit revenues excluding the impact that changes in fuel costs have had on ticket prices. Fuel expense represents a large percentage of our total operating expenses. Fluctuations in fuel prices often drive changes in unit revenues in the mid-to-long term. Although we believe it is useful to evaluate non-fuel unit costs for the reasons noted above, we would caution readers of these financial statements not to place undue reliance on unit costs excluding fuel as a measure or predictor of future profitability because of the significant impact of fuel costs on our business.

Although we are presenting these non-GAAP amounts for the reasons above, investors and other readers should not necessarily conclude that these amounts are non-recurring, infrequent, or unusual in nature.

20152016 COMPARED WITH 20142015

Our consolidated net income for 20152016 was$814 million, or $6.54 per diluted share, compared to net income of $848 million, or $6.56 per diluted share, compared to net income of $605 million, or $4.42 per diluted share, in 20142015. Our financial results include results of Virgin America for the period from December 14, 2016 through December 31, 2016 and the impact of purchase accounting as of December 14, 2016. Refer to the "Critical Accounting Estimates" section for further information regarding purchase accounting.

Excluding the impact of merger-related costs, mark-to-market fuel hedge adjustments and other special items, our adjusted consolidated net income for 20152016 was $842911 million, or $6.517.32 per diluted share, compared to an adjusted consolidated net income of $571842 million, or $4.186.51 per share, in 20142015.

Passenger RevenueMainline

Mainline passenger revenue for 20152016 increased by 4% ondue to a 10.7%9.9% increase in capacity, partially offset by a 5.8%5.4% decrease in PRASM compared to 20142015. The increase in capacity was driven by new routes larger aircraft added toand growth in our fleet, and increased utilizationoperating fleet. Virgin America capacity from the acquisition date through December 31, 2016 represented approximately 2 points of our aircraft.capacity increase from 2015. The decrease in PRASM was driven by a 4.4%decrease of 5.7% in ticket yield combined with a 1.2 pointdecrease in load factor compared to the prior year. The decline in ticket yield was primarily due to increased competitive capacity in the markets we serve,pressures and our own growth.growth, offset by a slight increase in load factor. Furthermore, the significant decline in fuel prices over the last year has had an impact oncontributed to lower ticket prices. The decline in load factor was also a result of increased capacity.

We expect competitive pressures on unit revenues to continue into 2016.2017. However, given our projected capacity growth, we expect total passenger revenue will increase from 2015, although likely less than our growth rate in capacity.2016 on a combined comparative basis that includes full 2016 capacity of Virgin America.

Passenger RevenueRegional

Regional passenger revenue increased by $4954 million, or 6%, compared to 20142015 due to a 9.7%16.5% increase in capacity, partially offset by a 3.4%an 8.7% decrease in PRASM compared to 20142015. The increase in capacity is due to an increase in departures andfrom new E175 deliveries, an increase in average aircraft stage length.length and the annualization of new routes introduced over the past twelve months. The decrease in PRASM was due to a 3.8%7.4% decrease in ticket yield, partially offset by an increaseas well as a decrease in load factor of 0.31.1 points. The declinedecrease in yield was due to an increase in competitive capacity in our regional markets and our own growth as we strengthen our network utility in the Pacific Northwest.Northwest, as well as an increase in the average trip length of our regional flights.

We expect Regional passenger revenue to increase in 2016,2017, primarily due to the delivery and placement into service of 18 E175s and the annualization of new routes introduced in 2015, and additional regional routes scheduled to be added in 2016.

OtherNet

Other—net revenue increased$22 $120 million,, or 3%17%, from 2014,2015, primarily due to increases in Mileage Plan revenue and food and beverage sales, partially offset by lower bag fee revenues.Plan™ revenue. Mileage PlanPlan™ revenue increased $34$100 million or 12%30%, due to increased miles sold. Foodsold and beverage sales were higher dueimproved compensation terms with our Mileage Plan™ affinity credit card partner as a result of a contract extension which became effective January 1, 2016. Additionally, Mileage Plan™ revenue earned from our partner airlines increased as compared to the 8.9% increase in passengers and selling more premium offerings, such as Tom Douglas signature meals. Bag fee revenue was lower due to promotions launched in January to offer a free first checked bag to our Mileage Plan members, and to all Alaska Airlines Signature Visa credit card holders beginning in February. This decline was partially offset by incremental revenue from our affinity card bank partner.prior year.

We expect our Other—net revenue to experience an increase, on a year over year basis, at a pace higher than the expected increase in passengers in 2016,2017, due primarilyto growth in the Mileage Plan™ program as we introduce Virgin America Elevate® members to the extended agreement with our affinity credit card bank partner effective January 1, 2016. We expect this agreement will result in an incremental $60 million of revenue in 2016.program, as well as continued organic growth amongst new and existing customers.

OPERATING EXPENSES

Total operating expenses decreased $106increased $282 million, or 2%7%, compared to 2014,2015, primarily as a result of higher wages and benefits and $117 million of merger-related costs, partially offset by lower fuel costs.

Wages increased10%, 8% on a 6.5% increase in FTEs. The increase in wages was primarily attributable to FTE growth to support expansion of our business and an increase in the average wages per employee.

Medical and other benefits increased 25% compared to the prior year. The increase is primarily due to an 8.8% increase in FTEsthe number of employees and the annualization of new labor contracts that included higher rates. The increase in FTEs was to support the growth in our business.high-cost medical claims.

Defined contribution plans increased 13%12% due to FTE growth and increased contributionsparticipation throughout all labor groups and an increased matched percentage as a part of recent labor contracts.groups.

Pension expense increased $19 million,decreased 11%, compared to the same period in the prior year. The increasedecrease is due to higher amortization of actuarial losses from previous years due primarily to a lower discount ratechange in several assumptions used to value the pension obligation at December 31, 2014.2015, including a higher discount rate, updated retirement age assumptions, future salary increase assumptions and others that resulted in lower expense recognition in 2016.

We expect wages and benefits to be 30% to 35% higher in 20162017 compared to 2015 on a 4%2016. The impact of Virgin America is approximately three quarters of the increase. The remainder is the expected growth in FTEs to 5% increase in FTEs.support our capacity growth, along with higher wages, pension costs and medical costs.

Variable Incentive Pay

Variable incentive pay expense increased to $120127 million in 20152016 from $116$120 million in 2014.2015. The increase is due to actual results exceeding our targets for financial performance more so than in the prior year, coupled with a higher wage base.

Aircraft Fuel

Aircraft fuel expense includes both raw fuel expense (as defined below) plusand the effect of mark-to-market adjustments to our fuel hedge portfolio included in our consolidated statement of operations as the value of that portfolio increases and decreases. Aircraft fuel expense can be volatile, even between quarters, because it includes these gains or losses in the value of the underlying instrument as crude oil prices and refining margins increase or decrease. Raw fuel expense is defined as the price that we generally pay at the airport, or the “into-plane” price, including taxes and fees. Raw fuel prices are impacted by world oil prices and refining costs, which can vary by region in the U.S.  Raw fuel expense approximates cash paid to suppliers and does not reflect the effect of our fuel hedges.

Aircraft fuel expense decreased$464 $123 million,, or 33%13% compared to 20142015. The elements of the change are illustrated in the following table:

Fuel gallons consumed increased 8.3%9.1% in line with theon our consolidated 10.6% increase in capacity, partially offset by a 2.2%1.4% improvement in fuel efficiency as measured by consolidated ASMs per gallon.
 
The raw fuel price per gallon decreased 38.5%19% as a result of lower West Coast jet fuel prices. West Coast jet fuel prices are impacted by both the price of crude oil as well asand the refining margins associated with the conversion of crude oil to jet fuel. The decrease in raw fuel price per gallon during 20152016 was due to a decline in crude oil prices of 48%11% and a decrease in refining margins of 11%36%, when compared to the prior year.
 
We also evaluate economic fuel expense, which we define as raw fuel expense adjusted for the cash we receive from, or pay to, hedge counterparties for hedges that settle during the period, and for the premium expense that we paid for those contracts. A key difference between aircraft fuel expense and economic fuel expense is the timing of gain or loss recognition on our hedge portfolio. When we refer to economic fuel expense, we include gains and losses only when they are realized for those contracts that were settled during the period based on their original contract terms. We believe this is the best measure of the effect that fuel prices are currently having on our business because it most closely approximates the net cash outflow associated with purchasing fuel for our operations. Accordingly, many industry analysts evaluate our results using this measure, and it is the basis for most internal management reporting and incentive pay plans.

Losses recognized for hedges that settled during the year were $1916 million in 20152016, compared to losses of $4119 million in 20142015. These amounts represent cash paid for premium expense, offset by any cash received from those hedges at settlement. The decrease in losses on settled hedges is primarily due to our increased use of "out of the money" call options as well as purchasing shorter-dated options, both of which reduce the premium cost we pay.

We currentlyAs of the date of this filing we expect our economic fuel price per gallon to beincrease approximately 37% lower39% in the first quarter of 2016 than2017 as compared to the first quarter of 20152016 of Air Group as reported due to lower West Coast jet fuelhigher crude oil prices and the decrease in premium costs related to our fuel hedge program.refining margins. As both oil prices and refining margins are volatile, we are unable to forecast the full-year cost with any certainty.

Aircraft Maintenance

Aircraft maintenance costsincreased by $17 million, or 7%, compared to the prior year. Maintenance costs increased primarily due to more engine and airframe events than in 2016. Additionally, in the prior year we received vendor credits, which offset expense, for engine maintenance that had been previously completed on the B737 fleet.

We expect aircraft maintenance to be approximately 50% to 55% higher in 2017 compared to 2016. The impact of Virgin America represents approximately three quarters of the increase. For Alaska, we expect an increase in engine maintenance costs primarily for our 737-800 aircraft, as we anticipate entering into a power-by-the-hour maintenance arrangement.



Aircraft Rent

Aircraft rent expense increased by $9 million, or 9%, compared to the prior year, primarily due the addition of the rent expense on the 53 Airbus aircraft leased by Virgin America for the period from December 14, 2016 to December 31, 2016.

We expect aircraft rent to be approximately 140% to 145% higher in 2017 compared to 2016 due to the full-year impact of the 53 leased Airbus aircraft, partially offset by a reduction in the number of leased B737-400 aircraft.

Landing Fees and Other Rentals

Landing fees and other rental expenses increased $24 million, or 8%, primarily due to increased flying in 2016, as we increased capacity and entered new markets.

We expect landing fees and other rental expenses to increase approximately 50% to 55% in 2017 with Virgin America representing about three quarters of the increase. The remainder of the increase relates to our expected capacity growth and rate increases at airports across our network.

Contracted Services

Contracted services increased$33 million, or 15%, when compared to 2015. The increase is primarily due to increased flying at stations where we use vendors to assist us. Additionally, wage rates for our vendor employees have increased due in part to higher minimum wage laws in many locations we serve. We also had several information technology and facilities projects that required contracted support.

We expect contracted services to be 50% to 55% higher in 2017 compared to 2016, primarily due to the addition of Virgin America, as well as the additional contracted services to be incurred as the companies are integrated.

Selling Expenses

Selling expenses increased by $14 million, or 7%, compared to 2015, mostly due to increased promotional and advertising activities, as well as new sponsorships which became effective in the current year.

We expect selling expense to increase approximately 65% to 70% in 2017 compared to 2016 primarily due to the addition of Virgin America.

Depreciation and Amortization

Depreciation and amortization expenses increased by $43 million, or 13%, compared to 2015. The increase is primarily due to the addition of 19 900ERs to our fleet since December 31, 2015, partially offset by a change in the estimated useful lives of certain B737 operating aircraft and related parts from 20 years to 25 years, which was effective October 1, 2016.

We expect depreciation and amortization expense to remain relatively flat in 2017 compared to 2016. The impact of Virgin America and newly delivered aircraft in 2017 is expected to be offset by a full year impact of the change in accounting estimate for useful lives mentioned previously.

Food and Beverage Service

Food and beverage service expenses increased by $13 million, or 12%, due to the increased number of passengers and upgrades to our onboard menu, offering higher quality food and beverage products.

We expect food and beverage expenses to increase 40% to 45% in 2017, primarily due to the acquisition of Virgin America.

Third-party regional carrier expense

Third-party regional carrier expense, which represents payments made to SkyWest and PenAir under our CPA agreements, increased $23 million, or 32%, in 2016 compared to 2015. The increase is primarily due to the significant increase in regional capacity in 2016 through the introduction of E175 flying.

We expect third-party regional carrier expense to increase in 2017 as we continue to expand our regional network.



Other Operating Expenses

Other operating expenses increased$9 million, or 3%, compared to 2015.  The increase is primarily due to increases in property and other taxes, personnel costs for our flight crews and an increase in fines and penalties.

We expect other operating expenses to increase approximately 50% to 55% in 2017 compared to 2016. The impact of Virgin America represents approximately half of the increase, while the other half is driven by IT and facilities-related projects.

Special Items—Merger-Related Costs and Other

We recorded special items of $117 million for merger-related costs associated with our acquisition of Virgin America. These costs consisted primarily of legal expenses, investment banking fees and severance costs. We expect to continue to incur merger-related costs in 2017. Our 2015 special items of $32 million consisted of a non-cash pension settlement expense and costs related to ongoing litigation.

Consolidated Nonoperating Income (Expense)

During 2016 we recorded nonoperating expense of $4 million, compared to nonoperating income of $14 million in 2015. In the current year, we incurred more interest expense associated with the financing obtained to fund the acquisition of Virgin America. This expense was partially offset by additional interest income earned during the period we held those funds in advance of the acquisition close date.
Additional Segment Information

Refer to Note 13 of the consolidated financial statements for a detailed description of each segment. Below is a summary of each segment's profitability.

Mainline

Pretax profit for Mainline was $1.3 billion in 2016 compared to $1.2 billion in 2015. This segment includes financial results of Virgin America from the date of acquisition through December 31, 2016. The $135 million increase is due to an increase in operating revenues of $277 million, offset by an increase in operating expenses of $126 million. Revenue growth was primarily driven by the $159 million increase in passenger revenues and the $100 million increase in Mileage Plan™ revenue, both described previously. Growth in operating expenses was due to higher wages to support our network growth, higher ramp and passenger handling due to increased flying and higher wage rates at stations where we use vendors to assist us, higher depreciation related to our fleet growth, and higher selling expenses related to increased advertising. Economic fuel cost, as defined above, decreased due to lower raw fuel costs and increased fuel efficiency, slightly offset by an 8% increase in consumption.

Regional

Pretax profit for Regional was $93 million in 2016 compared to $105 million in 2015. The $12 million decrease in pretax profit was driven by a $74 million increase in non-fuel operating expenses in the current year to support additional departures, partially offset by a $56 million increase in revenue and an $6 million decrease in fuel expense when compared to the prior year period.

Horizon

Pretax profit for Horizon was $14 million in 2016 compared to $28 million in 2015. CPA Revenues (100% of which are from Alaska and are eliminated in consolidation) increased due to additional capacity added in the last 12 months. The $32 million increase in Horizon's non-fuel operating expenses was largely driven by higher medical costs due to an increased number of large medical claims, increased volume of engine overhaul and heavy airframe work, employee signing bonuses and overhead restructuring costs.


2015 COMPARED WITH 2014

Our consolidated net income for 2015 was $848 million, or $6.56 per diluted share, compared to net income of $605 million, or $4.42 per diluted share, in 2014.

Excluding the impact of mark-to-market fuel hedge adjustments and special items, our adjusted consolidated net income for 2015 was $842 million, or $6.51 per diluted share, compared to an adjusted consolidated net income of $571 million, or $4.18 per share, in 2014.

Passenger Revenue—Mainline

Mainline passenger revenue for 2015increased by 4% on a 10.7% increase in capacity, partially offset by a 5.8% decrease in PRASM compared to 2014. The increase in capacity was driven by new routes, larger aircraft added to our fleet and increased utilization of our aircraft. The decrease in PRASM was driven by a 4.4% decrease in ticket yield, combined with a 1.2-point decrease in load factor compared to the prior year. The decline in ticket yield was primarily due to increased competitive capacity in the markets we serve and our own growth. Yield was further impacted by a significant decline in fuel prices, which has a direct impact on ticket pricing. The decline in load factor was also a result of increased capacity.

Passenger Revenue—Regional

Regional passenger revenue increased by $49 million, or 6%, compared to 2014 due to a 9.7% increase in capacity, partially offset by a 3.4% decrease in PRASM compared to 2014. The increase in capacity was due to an increase in departures and average aircraft stage length. The decrease in PRASM was due to a 3.8% decrease in ticket yield, partially offset by an increase in load factor of 0.3 points. The decline in yield was due to an increase in competitive capacity in our regional markets and our own growth as we strengthen our network utility in the Pacific Northwest.
Other—Net

Othernet revenue increased$22 million, or 3%, from 2014, due to increases in Mileage Plan™ revenue and food and beverage sales, partially offset by lower bag fee revenues. Mileage Plan™ revenue increased $34 million or 12%, due to increased miles sold. Food and beverage sales were higher due to the 8.9% increase in passengers and selling more premium offerings, such as Tom Douglas signature meals. Bag fee revenue was lower due to promotions launched in 2015 to offer a free first checked bag to our Alaska Airlines Signature Visa credit card holders. This decline was partially offset by incremental revenue from our affinity card bank partner.

OPERATING EXPENSES

Total operating expenses decreased $106 million, or 2%, compared to 2014, primarily as a result of lower fuel costs.

Wages increased 10%, primarily due to an 8.8% increase in FTEs and the annualization of new labor contracts that included higher rates. The increase in FTEs was to support the growth in our business.

Defined contribution plan expense increased 13% due to increased contributions throughout all labor groups and an increased matched percentage as a part of recent labor contracts.

Pension expense increased $19 million, compared to the same period in the prior year. The increase is due to higher amortization of actuarial losses from previous years due primarily to a lower discount rate used to value the pension obligation at December 31, 2014.

Variable Incentive Pay

Variable incentive pay expense increased to $120 million in 2015 from $116 million in 2014. The increase is due to actual results exceeding our targets for financial performance more so than in the prior year, coupled with a higher wage base.

Aircraft Fuel

Aircraft fuel expense decreased$464 million, or 33% compared to 2014. The elements of the change are summarized in the following table:

Fuel gallons508
   469
  

Fuel gallons consumed increased 8.3% in line with the 10.6% increase capacity, partially offset by a 2.2% improvement in fuel efficiency as measured by ASMs per gallon.

The raw fuel price per gallon decreased 38.5% as a result of lower West Coast jet fuel prices. West Coast jet fuel prices are impacted by both the price of crude oil, as well as refining margins associated with the conversion of crude oil to jet fuel. The decrease in raw fuel price per gallon during 2015 was due to a decline in crude oil prices of 48% and a decrease in refining margins of 11%, when compared to the prior year.

Losses recognized for hedges that settled during the year were $19 million in 2015, compared to losses of $41 million in 2014. These amounts represent cash paid for premium expense, offset by any cash received from those hedges at settlement. The


decrease in losses on settled hedges was primarily due to our increased use of "out of the money" call options as well as purchasing shorter-dated options, both of which reduce the premium cost we pay.

Aircraft Maintenance

Aircraft maintenance increased by $24 million, or 10%, compared to the prior year. Maintenance costs increased due to more scheduled engine maintenance events that were more expensive due to replacing life-limited parts and heavier airframe checks.




26




We expect aircraft maintenance to be 5% to 8% higher in 2016 primarily due to the timing of maintenance events as our fleet ages and from lease return costs as we return 13 B737-400 aircraft to lessors.

Landing Fees and Other Rentals

Landing fees and other rental expenses rentals increased $17$17 million, or 6%, primarily due to increased flying in 2015 as we increased capacity and entered into new markets.

We expect landing feesSelling Expenses
Selling expenses increased by $12 million, or 6%, compared to 2014, mostly due to increased promotional and other rental expenses to increaseadvertising activities in 2016 in line with the expected capacity growthSeattle and increased credit card commissions from higher rates at the airports where we operate.revenue.

Contracted Services

Contracted services increased$18 $18 million,, or 9%, when compared to 2014. The increase is primarily due to increased flying at stations where we use vendors to assist us with passenger and ramp handling.

We expect contracted services to be higher in 2016 due to higher rates and volumes as we continue to expand into new markets utilizing vendor services.

Selling Expenses

Selling expenses increased by $12 million, or 6%, compared to 2014, mostly due to increased promotional and advertising activities in Seattle and increased credit card commissions due to higher revenue.

We expect selling expense to increase approximately 10% in 2016, as we refresh our brand and increase promotion and advertising in our core markets, and as revenues increase.

Depreciation and Amortization

Depreciation and amortization expenses increased by $26 million, or 9%, due to the increased number of aircraft in our fleet and cabin upgrades made in the past 18 months.

We expect depreciationthroughout 2014 and amortization expense to increase approximately 15% in 2016 as we continue to purchase aircraft for replacement of leased aircraft and for growth.2015.

Food and Beverage Service

Food and beverage service expenses increased by $20 million, or 22%, due to the increased number of passengers and upgrades to our onboard menu, offering higher quality food and beverage products.

We expect food and beverage expenses to increase approximately 5% in 2016 primarily because of the expected increase in passengers.

Third-party regional carrier expense

Third-party regional carrier expense, which represents payments made to SkyWest and PenAir under our CPA agreements,CPAs, increased $14 million, or 24%, in 2015 compared to 2014. The increase is primarily due to the five E175 aircraft operated by SkyWest added to our regional operation in 2015.

We expect third-party regional carrier expense to increase in 2016 as we continue to expand our regional network.

Other Operating Expenses

Other operating expenses increased $48 million, or 16%, compared to 2014.2014.  The increase is primarily due to professional services with regard to our brand refresh and network strategy, personnel costs for our flight crews and IT-related costs.

We expect other operating expenses to increase 3% to 5% in 2016, primarily as a result of IT-related investments.



27




Special Items

In the fourth quarter ofDuring 2015 we recorded special items of $32 million ($20 million after tax).million. This is due to a $14 million million non-cash pension settlement expense related torecorded as a result of lump-sum payments made to terminated, vested participants which removed them from participation in the pension plan therefore reducing our outstanding liability, and an $18 million expense related to ongoing litigation.

Consolidated Nonoperating Income (Expense)

During 2015, we recorded nonoperating income of $14 million, compared to an expense of $13 million in 2014. In the prior year,2015, we recognized gains on the sale of certain equity securities. In the current year, we have capitalized more of our interest expense on an increasing balance of prepaid aircraft deposits.

Operating Costs per Available Seat Mile

We are presenting our line-item expenses below both in absolute dollars and on an ASM basis to highlight areas in which costs have increased or decreased either more or less than capacity.

Additional Segment Information

Refer to the NotesNote 13 of the Consolidated Financial Statementsconsolidated financial statements for a detailed description of each segment. Below is a summary of each segments' profitability.

Alaska

Mainline

Pretax profit for Alaska Mainline was $1.2 billion in 2015 compared to $834 million in 2014.2014. The $372 million increase is due to increased revenues of $188 million and decreased operating expenses of $192 million, slightly offset by a decrease in non-operating income of $8 million. Revenue growth was largely driven by the $165 million increase in Mainline passenger revenue is described previously. MainlineGrowth in operating expense excluding fuel increased by $236 million,expenses was due to higher wages to support our growth, higher ramp and passenger handling associated with increased flying, higher depreciation related to our fleet growth, and increased food and beverage costs. Economic fuel cost, as defined above, decreased due to lower raw fuel costs and increased fuel efficiency, slightly offset by an increase in consumption.

Alaska Regional

Pretax profit for Alaska Regional was $105 million in 2015 compared to $74 million in 2014.2014. The $49$31 million increase in Alaska Regional passenger revenue is described above. The increase in revenue and the significant decline in fuel costs were partiallydue to increased revenues of $43 million, offset by increased operating expense of $13 million. Revenue growth was driven by increased passenger revenue. Operating expenses were higher expensesin 2015 to support additional departures.




28




Horizon

Pretax profit for Horizon was $28 million in 2015 compared to $17 million in 2014.2014. The $11 million increase is due to increased CPA Revenues (100% of which are from Alaska and eliminated in consolidation) of $36 million, offset by increased due to additional capacity and higher rates.non-fuel operating expenses of $26 million. The $26 million increase in Horizon's non-fuel operating expenses was largely driven by increased engine maintenance and other expenses to support the increase in capacity.

2014 COMPARED WITH 2013

Our consolidated net income for 2014 was $605 million, or $4.42 per diluted share, compared to net income of $508 million, or $3.58 per diluted share, in 2013. Significant items impacting the comparability between the periods are as follows:

Both periods include adjustments to reflect the timing of net unrealized mark-to-market gains or losses related to our fuel hedge positions. For 2014, we recognized net mark-to-market losses of $23 million ($15 million after tax, or $0.11 per diluted share) compared to gains of $8 million ($5 million after tax, or $0.03 per share) in 2013.

In 2014, we recognized a one-time, non-cash benefit from the curtailment of certain post-retirement benefit plans of $20 million and a one-time gain associated with the settlement of a legal matter of $10 million. The aggregate $30 million ($19.0 million in aggregate after tax, or $0.13 per diluted share) is included in Special items in the consolidated statement of operations.

In 2013, we recognized a one-time, non-cash Special mileage plan revenue item of $192 million ($120 million after tax, or $0.85 per diluted share) that resulted from the application of new accounting rules associated with the modified Bank of America Affinity Card Agreement, and the effect of an increase in the estimate of the number of frequent flier miles expected to expire unused.

Excluding the mark-to-market fuel hedge adjustments, special items, and the one-time Special mileage plan revenue item, our adjusted consolidated net income for 2014 was $571 million, or $4.18 per diluted share, compared to an adjusted consolidated net income of $383 million, or $2.70 per share, in 2013.

Passenger Revenue – Mainline

Mainline passenger revenue for 2014increased by 8% on a 6.6% increase in capacity and a 1.4% increase in PRASM compared to 2013. The increase in capacity was driven by new routes, seats added to our existing fleet as part of our cabin improvement project, and delivery of 10 737-900ERs in 2014. The increase in PRASM was driven by a 1.9% increase in ticket yield, partially offset by a 0.4-point decrease in load factor compared to the prior year. Increase in yield was due to reallocation of capacity to markets with stronger demand and by a change in revenue allocation between Mainline and Regional service because of certain industry pricing changes. Without the industry change, Mainline yields would have increased by 0.9%.

Passenger Revenue – Regional

Regional passenger revenue increased by $28 million, or 4%, compared to 2013 on an 11.9% increase in capacity, partially offset by a 7.3% decline in PRASM compared to 2013. The decrease in PRASM was due to a 6.2% decrease in ticket yield coupled with a 1.0-point decrease in load factor compared to the prior year. The decline in yield was primarily driven by a change in revenue allocation between Mainline and Regional service because of certain industry pricing changes. Without the revenue allocation adjustment, yield would have decreased 1.7%. Additionally, the average trip length for our Regional flights increased 3% in 2014, which also put downward pressure on yields.




30




Other – Net

Othernet revenue increased$91 million, or 16%, from 2013.  This is primarily due to an increase in our Mileage Plan™ revenues of $39 million, or 15%, due to an increase in miles sold and an increase in cash received per mile. Additionally, bag fees and ticket change fees are up 23% and 12%, respectively, due to changes in our fee structure that took effect in November 2013.

Special Mileage Plan Revenue

In 2013, we modified and extended our co-branded credit card agreement with BAC. In connection with this agreement and as a result of applying related accounting standards, we recorded a one-time, non-cash Special mileage plan revenue item of $192 million primarily related to our revaluation of the deferred revenue liability related to miles previously sold to Bank of America Corporation (referred to herein as BAC).

OPERATING EXPENSES

Total operating expenses increased$88 million, or 2%, compared to 2013, primarily driven by higher non-fuel costs due to increased capacity. We believe it is useful to summarize operating expenses as follows, which is consistent with the way expenses are reported internally and evaluated by management:

Wages increased 9%, primarily due to annualization of new labor contracts that included higher rates, a 4.7% increase in full-time equivalent employees, and an $8 million signing bonus paid to Alaska's flight attendants in December 2014 in connection with the ratification of a new collective bargaining agreement. the increase in FTEs was to support the growth in our business.

Defined contribution plan expense increased 20% due to an increase in the number of employees participating in the plans and an increase in the employer contribution for non-union employees previously in the pension plan.

Pension expense decreased 82%, compared to the same period in the prior year. The decline is due to having a lower accumulated loss to amortize as a result of higher plan assets, a higher discount rate at December 31, 2013 compared to December 31, 2012, and the freezing of plan benefits for our non-union employees beginning January 1, 2014.





31




Variable Incentive Pay

Variable incentive pay expense increased from $105 million in 2013 to $116 million in 2014. The increase is due to actual results exceeding our target results of financial and operational performance more so than in the prior year.

Fuel gallons consumed increased 4.9% in line with the increase in departures and capacity, partially offset by a 2.1% improvement in fuel efficiency as measured by ASMs per gallon.

The raw fuel price per gallon decreased 6.3% as a result of lower West Coast jet fuel prices. The decrease in raw fuel price per gallon during 2014 was due to a decrease in average crude oil prices of 5% and a decline in refining margins of 16%, as compared to the prior year.

Losses recognized for hedges that settled during the year were $41 million in 2014, compared to losses of $52 million in 2013. These amounts represent the cash received, or paid, net of the premium expense recognized for those hedges.

Aircraft Maintenance

Aircraft maintenance decreased by $18 million, or 7%, compared to the prior year. The decrease is primarily due to a $22 million reduction in our power-by-the-hour (PBH) expense, $11 million in lower lease return costs, and five fewer unscheduled engine checks for our Q400 aircraft. Offsetting these decreases was an $11 million increase in engine maintenance expense primarily related to our 737-400 engines, and slightly higher airframe checks for both our 737 and Q400 fleet.

The decrease in our PBH expense is due to fewer engines covered by the contracts in the current year, along with reduced flying on the engines that are still under the current contract. The decrease is return costs is due to the four aircraft we returned during the current year and two aircraft we returned at the end of the prior year with no lease return costs expected for lease returns in 2015.

Landing Fees and Other Rentals

Landing fees and other rentals increased$17 million, or 6%, primarily due to increased flying in 2014 as we increased capacity and entered into new markets.

Contracted Services

Contracted services increased $20 million, or 11%, primarily due to $15 million increase in contract ramp and passenger handling costs resulting from new stations and rate increases in Seattle.

Selling Expenses

Selling expenses increased by $20 million, or 11%, compared to 2013, mostly due to increased promotional and advertising activities in Seattle and increased credit card commissions from higher revenue.



32




Depreciation and Amortization

Depreciation and amortization expenses increased by $24 million, or 9%, due to increased number of aircraft in our fleet.

Food and Beverage Service

Food and beverage service expenses increased by $9 million, or 11%, due to the increased number of passengers, and more premium product offerings.

Third-party regional carrier expense

Third-party regional carrier expense, which represents payments made to SkyWest and PenAir under our CPA agreements, increased $13 million, or 29%, in 2014 compared to 2013. The increase is primarily due to the three additional lines of flying performed by SkyWest in 2014 compared to 2013.

Other Operating Expenses

Other operating expenses increased$30 million, or 11%, compared to 2013.  The increase is primarily driven by IT project costs, higher professional fees, and flight crew hotel costs.

Special Items

In the fourth quarter of 2014, we recorded special items for $30 million. This is primarily due to a $20 million non-cash curtailment gain related to certain post-retirement benefits that were reduced in 2014. The remaining gain is related to a one-time cash settlement related to a legal matter.

Consolidated Nonoperating Income (Expense)

During 2014, we recorded nonoperating income of $13 million, compared to an expense of $22 million in 2013. The $35 million favorable change is due to gains recorded in the current year related to the sale of certain equity securities and reduced interest expense due to lower average debt levels. Additionally, in the prior year, we incurred costs of $12 million to overhaul and repair three aircraft that were previously subleased to another carrier.

Additional Segment Information

Refer to the Notes of the Consolidated Financial Statements for a detailed description of each segment. Below is a summary of each segments' profitability.

33





Alaska Mainline

Pretax profit for Alaska Mainline was $834 million in 2014 compared to $530 million in 2013. The $284 million increase in Mainline passenger revenue is described previously. Mainline operating expense excluding fuel increased by $124 million, due to increased capacity, departures, expanding to new locations, and higher advertising and promotional activity in Seattle and our new locations. Additionally, we increased spending on IT infrastructure projects, and incurred more depreciation as we continue to purchase aircraft. Economic fuel cost as defined above decreased due to a decline in the economic price per gallon, and increased fuel efficiency, slightly offset by an increase in consumption.

Alaska Regional

Pretax profit for Alaska Regional was $74 million in 2014 compared to $69 million in 2013. The $28 million increase in Alaska Regional passenger revenue is described previously. The increased Regional revenue was offset by higher expenses to support additional capacity. Additionally, we recorded a $12 million loss in 2013 related to overhaul and repair of three aircraft that were previously subleased to another carrier.

Horizon

Pretax profit for Horizon was $17 million in 2014 compared to $20 million in 2013. CPA Revenues (100% of which are from Alaska and eliminated in consolidation) increased due to additional capacity in the state of Alaska. The $8 million increase in Horizon's non-fuel operating expenses was driven by increased wages to support additional aircraft in the fleet, higher pilot training costs, and increased depreciation and amortization due to the three additional Q400 aircraft added in Q4 of 2013.

LIQUIDITY AND CAPITAL RESOURCES
 
Our primary sources of liquidity are:
 
Our existing cash and marketable securities balance of $1.31.6 billion, and our expected cash from operations;
 
Our 8952 unencumbered aircraft in the operating fleet as of December 31, 20152016, that could be financed, if necessary; and

Our combined $200 million bank line-of-credit facilities, with none currently outstanding.

On December 14, 2016 we completed the acquisition of Virgin America, paying $2.6 billion to stockholders and other equity holders of Virgin America. We funded the acquisition with cash on hand and approximately $2.0 billion of secured debt financing provided by multiple lenders. Approximately $1.6 billion of the loans obtained to fund the acquisition are secured by a total of 56 of Air Group's aircraft, including 37 B737-900ER aircraft and 19 B737-800 aircraft. The remainder is secured by Air Group's interest in certain aircraft purchase agreements. As a result, we have fewer unencumbered aircraft in our operating fleet than in prior periods, which could affect our ability to obtain future financing.

In 20152016, we took free and clear delivery of 1119 B737-900ER aircraft. Weaircraft and made debt payments totaling $116$249 million. In addition, weWe also continued to return capital to our shareholders by paying dividends totaling $136 million and repurchasing $505193 million of our common stock in 2015, and paid dividends totaling $102 million.stock. Because of our strong balance sheet and financial performance, we are one of only twothree airlines in the U.S. with investment grade credit ratings. We will continue to focus on preserving a strong liquidity position and evaluate our cash needs as conditions change.  

We believe that our current cash and marketable securities balance combined with future cash flows from operations and other sources of liquidity will be sufficient to fund our operations and meet our debt payment obligations for the foreseeable future.

In our cash and marketable securities portfolio, we invest only in securities that meet our primary investment strategy of maintaining and securing investment principal. The portfolio is managed by reputable firms that adhere to our investment policy that sets forth investment objectives, approved and prohibited investments, and duration and credit quality guidelines. Our policy and the portfolio managers are continually reviewed to ensure that the investments are aligned with our strategy.

The following discussion summarizes the primary drivers of the increase in our cash and marketable securities balance and our expectation of future cash requirements.

ANALYSIS OF OUR CASH FLOWS
 
Cash Provided by Operating Activities
 
Net cash provided by operating activities was $1.4 billion in 2016 compared to $1.6 billion in 2015. The decrease of $198 million is due to a decline in operating results primarily driven by an increase in non-fuel operating expenses—including $117 million in merger-related costs associated with the acquisition of Virgin America—partially offset by higher revenues and lower fuel costs.

In 2015, we generated $1.6 billion in operating cash flows compared to $1.0 billion in 2014.2014. The increase of $554 million was primarily attributable to improved operating results, driven largely by lower jet fuel costs.

Cash provided by operating activities was $1 billion in 2014, compared to $981 million in 2013. The $49 million increase is primarily due to an increase in earnings, and an increase in our advance ticket sales, partially offset by a $177 million increase in payments for income taxes.

We typically generate positive cash flows from operations, and expect to use a portionthat cash flow to invest inbuy aircraft and capital expendituresequipment, to make debt payments, and increasing shareholder value throughto return capital to shareholders. During 2016, we paused our share repurchase program as we prepared for the repurchaseacquisition of our common stock and dividends.Virgin America.

Cash Used in Investing Activities
 
Cash used in investing activities was $930 million2.6 billion during 2015,2016, compared to $541930 million in 20142015. We used $2.0 billion to acquire Virgin America, representing $2.6 billion consideration paid, offset by $645 million of cash acquired. Our capital expenditures were $831678 million, or $137153 million higherlower than in 20142015. This is due as a result of fewer aircraft purchase deposits made during 2016 as compared to the2015. During 2016 we took delivery of 1119 B737-900ERs, one Q400 aircraft, and made advance purchase deposits on 32 B737 and E175 aircraft that will be delivered over the next 24 months. This compares to the delivery of ten11 B737-900ERs and one Q400 in the prior year. In 2015, we replaced restricted cash on deposit of $52 million with a line of credit facility, resulting in an increase in investing cash flows.

As of December 31, 2015,2016, we had firm commitments for 6854 B737 aircraft through 20222023 with options to acquire up to 4641 additional 737B737 NextGen (NG) aircraft and MAX aircraft in 20182019 through 2024. We alsohave lease commitments for 10 A321neo aircraft with deliveries in 2017 through 2018 and an order for 30 A320neos with deliveries starting in 2020 through 2022. This order is cancelable with the forfeiture of $15 million of predelivery payments. We have firm commitments for two Q400sto purchase or lease 38 E175 aircraft with deliveries from 2017 through 2019 and options to acquire five Q40030 E175 aircraft with deliveries from 20182019 to 2019, although we do not currently expect to take delivery of the firm orders or exercise the options. In addition to the five E175 aircraft currently operating2021 and lease an additional 8 with deliveries in our regional fleet, we have commitments to lease 18 E175 aircraft with start dates in 2016 through 2017. We also have options to lease eight E175 aircraft with positions starting in late 2017 and early 2018.2019. The options for all fleet types give us the flexibility, but not the obligation, to grow the fleet assuming profitability and return on invested capital targets can be met.

Additionally, we may purchase up to 30 regional jets to be operated by Horizon with deliveries starting in 2017. At this time, no order has been placed nor have any commercial terms been agreed upon.

The table below reflects total expected capital expenditures and the additional expenditures if options were exercised.exercised as of February 28, 2017. Additional options will be exercised only if we believe return on invested capital targets can be met:

Cash used in investing activities was $930 million during 2015, compared to $541 million during 2014, compared to $698 million in 2013.2014. Our capital expenditures were $694$831 million in 2014, or $1282015, $137 million higher than in 2013. This is due to the delivery of ten B737-900ER aircraft, the completion of our B737 cabin improvement project, and the exercise of 16 B737 options, two Q400 options, and deposits for an incremental Q400 in 2014.

Cash UsedProvided by Financing Activities
 
Cash usedprovided by financing activities was $1.5 billion during 2016, compared to cash used of $688 million during 2015, compared toin 2015. During the year, we secured debt proceeds of $2 billion for the acquisition of Virgin America, made debt payments of $249 million, repurchased $462193 million in 2014. During the current year,of our common stock and paid cash dividends of $136 million. In 2015, we made debt payments of $116 million, stock repurchases of $505$505 million, and cash dividend payments of $102 million. In 2014, we made debt payments of $119 million and stock repurchases of $348 million, and cash dividend payments of $68 million, partially offset by proceeds from debt of $51 million. In 2013, we made debt payments of $161 million and stock repurchases of $159 million.
 
We plan to meet our future capital and operating commitments through our cash and investments on hand, internally generated cash from operations, along with additional debt financing if necessary.

CONTRACTUAL OBLIGATIONS AND COMMITMENTS
 
Aircraft Purchase Commitments
 
AtAs of December 31, 2015,2016, we had firm orders to purchase or lease 70102 aircraft. We also have an order for 30 Airbus A320neo with deliveries from 2020 through 2022 with an option to cancel up to three years in advance of delivery in groups of five aircraft. We could incur a loss of pre-delivery payments and credits as a cancellation fee. We also have options to acquire 4641 B737 aircraft with deliveries from 2019 through 2024 and options to acquire five Q40030 E175 aircraft although we do not expect to exercise the Q400 options.with deliveries from 2019 through 2021. In addition to the five15 E175 aircraft currently operated by SkyWest in our regional fleet, we have commitmentsoptions in future periods to lease 18add regional capacity by having SkyWest operate up to 8 more E175 aircraft with start dates in 2016 and 2017. We have options for eight additional E175 aircraft with positions starting in late 2017 and early 2018.

As mentioned previously, we may order 30 regional jets to be operated by Horizon with deliveries starting in 2017. As no commercial terms have been reached at this time, delivery positions and future capital expenditures are excluded from the fleet table and commitment table below. However, if the order is placed in 2016, we would expect additional capital expenditures of approximately $40 million in 2016.aircraft.

Future Fuel Hedge Positions

All of our future oil positions are call options, which are designed to effectively cap the cost of the crude oil component of our jet fuel purchases. With call options, we are hedged against volatile crude oil price increases; and, during a period of decline in crude oil prices, we only forfeit cash previously paid for hedge premiums. Our crude oil positions are as follows:

This results in a 92%90% funded status on a projected benefit obligation basis compared to 94%92% funded as of December 31, 20142015.

We have agreements with a number of credit card companies to process the sale of tickets and other services. Under these agreements, there are material adverse change clauses that, if triggered, could result in the credit card companies holding back a reserve from our credit card receivables. Under one such agreement, we could be required to maintain a reserve if our credit rating is downgraded to or below a rating specified by the agreement or our cash and marketable securities balance fell below $500 million. Under another such agreement, we could be required to maintain a reserve if our cash and marketable securities balance fell below $500 million. We are not currently required to maintain any reserve under these agreements, but if we were, our financial position and liquidity could be materially harmed.agreements.
 
Deferred Income Taxes

For federal income tax purposes, the majority of our assets, as measured by value, are fully depreciated over a seven-year life using an accelerated depreciation method or bonus depreciation if available. For financial reporting purposes, the majority of our assets are depreciated over 15 to 2025 years to an estimated salvage value using the straight-line basis. This difference has created a significant deferred tax liability. At some point in the future the depreciation basis will reverse, potentially resulting in an increase in income taxes paid.

While it is possible that we could have material cash obligations for this deferred liability at some point in the future, we cannot estimate the timing of long-term cash flows with reasonable accuracy. Taxable income and cash taxes payable in the short term are impacted by many items, including the amount of book income generated, which can be volatile depending on revenue and fuel prices, levelusage of pension funding (which is generally not known until late each year),net operating losses, whether "bonus depreciation" provisions are available, as well as other legislative changes that are beyond our control.

In 20152016, we made tax payments, net of refunds, totaling $349459 million, and had an effective tax rate of 35.4%39.5%. We expect our effective tax rate to be in the range of 36%37% to 38% for 20162017 and the effective rate of cash paid for income taxes to be in the range of 30%20% to 35%25% of book income, although these estimates are subject to change. We believe that we will have the liquidity available to make our future tax payments.

CRITICAL ACCOUNTING ESTIMATES
 
The discussion and analysis of our financial position and results of operations in this MD&A are based upon our consolidated financial statements. The preparation of these financial statements requires us to make estimates and judgments that affect our financial position and results of operations. See Note 1 to the consolidated financial statements for a description of our significant accounting policies.

Critical accounting estimates are defined as those that reflect significant management judgment and uncertainties and that potentially may result inlead to materially different results under varying assumptions and conditions. Management has identified the following critical accounting estimates and has discussed the development, selection and disclosure of these policies with our audit committee.
 
MILEAGE PLANFREQUENT FLYER PROGRAMS
 
OurAlaska's Mileage Plan™ loyalty program awards miles to members who fly on our airlines and our airline partners. We also sell services, including miles for transportation, to non-airline partners, such as hotels, car rental agencies and a major bank that offers Alaska Airlines affinity credit cards. In either case, the outstanding miles may be redeemed for travel on our airlines or any of our airline partners. As long as the Mileage Plan™ is in existence, we have an obligation to provide this future travel.

Virgin America's Elevate® program allows guests to earn points for purchasing travel that are redeemable for travel awards throughout our network and the networks of Virgin America's airline partners. A liability for all points outstanding as of December 14, 2016 was recorded at the estimated fair value as part of our acquisition of Virgin America. The fair value was estimated using the estimated ticket value of points expected to be redeemed as of the date of the acquisition. See "Business Combination Accounting, Goodwill and Intangibles" discussion below for estimates used for purchase accounting.

For miles earned by passengersguests who fly on us or our airline partners, we recognize a liability and a corresponding selling expense representing the incremental cost associated with the obligation to provide travel in the future. For services sold through one of our non-airline partners, the sales proceeds that represent award transportation and certificates for discounted companion travel are deferred and recognized when the transportation is delivered, and the remaining components are recorded as commission in other-netother—net revenue in the period the services are performed. Commission revenue recognized for the years ended December 31, 2015


2016, 20142015 and 20132014 was $280329 million, $261280 million and $213261 million, respectively. The deferred revenue is recognized as passenger revenue when the award travel occurs, or the miles expire, and as other-netothernet revenue for awards issued and flown on partner airlines.
 
At December 31, 20152016, we had approximately 161186.5 billion miles and points outstanding, resulting in an aggregate liability and deferred revenue balance of $814 million1.1 billion. Both the liability and the deferred revenue are determined based on several assumptions that require significant management judgment to estimate and formulate. There are uncertainties inherent in these estimates; therefore,estimates. Therefore, different assumptions could affect the amount and/or timing of revenue recognition or Mileage Plan™ expenses. The most significant assumptions in accounting for the Mileage Plan™ are described below.

1.The rate at which we defer sales proceeds related to services sold through non-airline partners:
 
We use the relative selling price method for the deferral of sales proceeds. For contracts that were modified after the effective date of Accounting Standards Update 2009-13, "Multiple-Deliverable Revenue Arrangements - Arrangements—a consensus of the FASB Emerging Issues Task Force" (ASU 2009-13)("ASU 2009-13"), we determined our 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 miles awarded and the number of miles redeemed. We estimated the selling prices and volumes over the terms of the agreements in order to determine the allocation of proceeds to each of the multiple deliverables. This relative allocation is evaluated annually and updated according to changes in the assumptions of the volume of related deliverables. A 1% shift between the allocation of cash proceeds to travel deliverables from marketing deliverables would defer the timing of revenue recognition by approximately $6$8 million.

2.The number of miles that will not be redeemed for travel (breakage):
 
The liability for outstanding Mileage Plan™ mileage credits includes all mileage credits that are expected to be redeemed, including mileage credits earned by members whose mileage account balances have not yet reached the minimum mileage credit level to redeem an award. Our estimate of the number of miles that will not be redeemed (breakage) considers historical activity in our members’ accounts and other factors. Based on statistical analysis of historical data, our current breakage rate is 17.4%. A hypothetical 1% change in our estimate of breakage has approximately a $7an $8 million effect on the liability.

3.The number of miles used per award:
 
We estimate how many miles will be used per award. For example, our members may redeem credit for award travel to various locations or choose between a highly restricted award and an unrestricted award. Our estimates are based on the current requirements in our Mileage Plan™ program and historical award redemption patterns.

4.The number of awards redeemed for travel on our airlines versus other airlines:
 
The cost for us to carry an award passenger is typically lower than the cost we will pay to our travel partners. We estimate the number of awards that will be redeemed on our airlines versus on our travel partners and accrue the estimated costs based on historical redemption patterns. If the number of awards redeemed on our travel partner is higher or lower than estimated, we may need to adjust our liability and corresponding expense.

5.The costs that will be incurred to provide award travel:travel for miles earned by guests who fly on us or our airline partners:
 
When a frequent flierflyer travels on his or her award ticket on one of our airlines, incremental costs such as food, fuel and insurance are incurred to carry that passenger. We estimate what these costs will be (excluding any contribution to overhead and profit) and accrue a liability. If the passengerguest travels on another airline on an award ticket, we often must pay the other airline for carrying the passenger.guest. The other airline costs are based on negotiated agreements and are often substantially higher than the costs we would incur to carry that passenger.guest. We estimate how much we will pay to other airlines for future travel awards based on historical redemptions and settlements with other carriers and accrue a liability accordingly. The costs actually incurred by us or paid to other airlines may be higher or lower than the costs that were estimated and accrued, and therefore we may need to adjust our liability and recognize a corresponding expense.
 
We regularly review significant Mileage Plan™ assumptions and change our assumptions if facts and circumstances indicate that a change is necessary. Any such change in assumptions could have a significant effect on our financial position and results of operations.



PENSION PLANS
 
Our actuarial estimates of pension liability, the related expense and the associated significant assumptions are discussed in Note 7.8 to the consolidated financial statements.   

The calculation of pension expense and the corresponding liability requires the use of a number of importantkey assumptions, including the expected long-term rate of return on plan assets and the assumed discount rates to be used in the calculation of the projected benefit obligation and the interest and service cost. Changes in these assumptions can result in different expense and liability amounts, and future actual experience can differ from these assumptions.

Pension liability and future pension expense decrease as the discount rate used for the obligation increases. We discounted future pension obligations using rates between 4.29% and 4.50% at December 31, 2016 and between 4.55% and 4.69% at December 31, 2015 and a rate of 4.20% at December 31, 2014.2015. The discount rates were determined using current rates earned on high-quality, long-term bonds with maturities that correspond with the estimated cash distributions from each of the four defined-benefit pension plans. The discount rates we use are based on a yield curve that uses a pool of higher-yielding bonds estimated to be more in line with settlement rates, as we have taken steps to ultimately terminate or settle plans that are frozen and move toward freezing benefits in active plans in the future. If the discount rate decreased by 0.5%, our projected benefit obligation at December 31, 20152016 would increase by approximately $128132 million and our estimated 20162017 pension expense would increase by approximately $8 million.

Pension liability and future pension expense can increase or decrease as assumptions in the actuarial data changes. InFor example, in 2015 we engaged our third-party actuary to update demographic assumptions used in the valuation of the defined-benefit pension liabilities. These assumptions included updates such as estimated salary increases, employee turnover and retirement rates, among other items. The changes in these assumptions decreased our projected benefit obligation by approximately $50 million at December 31, 2015. The primary cause of the decline was the change in expected participant retirement rates. The study found that eligible employees are retiring later than they had in our previous assumption update, resulting in lower expected cash flows post retirement.

Pension expense normally increases as the expected rate of return on pension plan assets decreases. As of December 31, 20152016, we estimate that the pension plan assets will generate long-term rates of return between 6.00%5.50% and 6.50%6.00%, which compares to 6.5%6.0% and 6.50% at December 31, 20142015. We regularly review the actual asset allocation and periodically rebalance investments as appropriate. This expected long-term rate of return on plan assets at December 31, 20152016 is based on an allocation of U.S. and non-U.S. equities, U.S. fixed-income securities, and real estate. A decrease in the expected long-term rate of return of 0.5% would increase our estimated 20162017 pension expense by approximately $8$9 million.

All of our defined-benefit pension plans are now closed to new entrants. Additionally, benefits in our non-union defined-benefit plans were frozen January 1, 2014. Furthermore, in 2015, we offered lump sum payments to certain terminated, vested participants in our defined-benefit pension plans in order to eliminate a significant portion of our outstanding liability. As a result, we reduced our projected benefit obligation by $62 million and recorded a settlement charge of $14 million in 2015, which is included in Special Items on the consolidated statement of operations.
 
Future changes in plan asset returns, assumed discount rates and various other factors related to the participants in our pension plans will impact our future pension expense and liabilities. We cannot predict what these factors will be in the future.
 
LONG-LIVED ASSETS
 
As of December 31, 20152016, we had approximately $4.85.7 billion of property and equipment and related assets, net of accumulated depreciation. In accounting for these long-lived assets, we make estimates about the expected useful lives of the assets, changes in fleet plans, the expected residual values of the assets and the potential for impairment based on the fair value of the assets and the cash flows they generate. Effective October 1, 2016, we changed our estimate of useful lives for certain B737 aircraft from 20 years to 25 years to better align with their operational performance, maintenance experience and industry practice. Factors indicating potential impairment include, but are not limited to, significant decreases in the market value of the long-lived assets, management decisions regarding the future use of the assets, a significant change in the long-lived assets condition, and operating cash flow losses associated with the use of the long-lived asset.

There is inherent risk in estimating the fair value of our aircraft and related parts and their salvage values at the time of impairment. Actual proceeds upon disposition of the aircraft or related parts could be materially less than expected, resulting in additional loss. Our estimate of salvage value at the time of disposal could also change, requiring us to increase the depreciation expense on the affected aircraft. 



BUSINESS COMBINATION ACCOUNTING, GOODWILL AND INTANGIBLES

To record the value of assets acquired and liabilities assumed as a result of our acquisition of Virgin America on December 14, 2016, we have performed a purchase price allocation utilizing the best information available to management. The purchase price allocation is provisional and is subject to further adjustments as additional information becomes available concerning the fair value of the assets acquired and liabilities assumed with any adjustments to the purchase price allocation to be made as soon as practicable but no later than December 14, 2017. The fair values of the assets acquired and liabilities assumed were determined using market, income or cost methods. Our consolidated balance sheet reflects goodwill in the amount of $1.9 billion at December 31, 2016, representing the excess of the purchase price over the fair value of Virgin America’s tangible and identifiable intangible assets and liabilities. Identifiable intangible assets recorded totaled approximately $143 million at December 31, 2016 and consisted of customer relationships, airport slots and gates. With the exception of airport slots, all of the identified intangible assets are finite-lived and are being amortized over their estimated economic useful lives. Goodwill and indefinite-lived intangible assets are not amortized, but will be tested for impairment at least annually (in the fourth quarter), or more frequently if events or circumstances indicate that an impairment may exist.

Our impairment analysis may include a qualitative assessment to determine whether it is more likely than not that a reporting unit or intangible asset group is impaired. If we do not perform a qualitative assessment, or if we determine it is more likely than not that the fair value of the reporting unit or intangible asset group exceeds its carrying amount, we will calculate the estimated fair value of the reporting unit or intangible asset group and an impairment charge would be recorded to reduce the carrying value to the estimated fair value.

Qualitative factors that might indicate a need to perform an impairment analysis outside of the regular annual assessment could include, but are not limited to: 1) reduced passenger demand as a result of domestic or global economic conditions; 2) significantly ongoing higher prices for jet fuel; 3) significant ongoing lower fares or passenger yields as a result of increased competition or lower demand; 4) a significant increase in future capital expenditure commitments; and 5) significant disruptions to our 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.

Our business combination accounting, as well as future impairment analyses, require management to make assumptions and apply judgment. Key assumptions include, but are not limited to, estimating future cash flows, selecting discount rates and selecting valuation methodologies. These estimates and assumptions are highly subjective and our ability to realize the future cash flows used in our fair value calculations may be affected by changes in economic condition, our economic performance or business strategies.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
 
We have interest-rate risk on our variable-rate debt obligations and our available-for-sale marketable investment portfolio, and commodity-price risk in jet fuel required to operate our aircraft fleet. We purchase the majority of our jet fuel at prevailing market prices and seek to manage market risk through execution of our hedging strategy and other means. We have market-sensitive instruments in the form of fixed-rate debt instruments and financial derivative instruments used to hedge our exposure to jet-fuel price increases and interest-rate increases. We do not purchase or hold any derivative financial instruments for trading purposes.
 
Aircraft Fuel
 
Currently, our fuel-hedging portfolio consists of crude oil call options. Call options effectively cap our pricing for the crude oil, limiting our exposure to increasing fuel prices for about half of our planned fuel consumption. With call options, we are hedged against volatile crude oil price increases, and, during a period of decline in crude oil prices, we only forfeit cash previously paid for hedge premiums. We believe there is risk in not hedging against the possibility of fuel price increases. We estimate that a 10% change in the forward curve for crude oil prices as of December 31, 20152016 would increase or decrease the fair value of our crude oil hedge portfolio to approximately $8$45 million or $2$7 million, respectively.

38





Our portfolio value of fuel hedge contracts was $4$20 million at December 31, 20152016 compared to a portfolio value of $74 million million at December 31, 20142015. We do not have any collateral held by counterparties to these agreements as of December 31, 20152016.
 


We continue to believe that our fuel hedge program is an important part of our strategy to reduce our exposure to volatile fuel prices. We expect to continue to enter into these types of contracts prospectively, although significant changes in market conditions could affect our decisions. For more discussion, see the "Derivative Instruments" note inNote 4 to our consolidated financial statements.
 
Interest Rates
 
We have exposure to market risk associated with changes in interest rates related primarily to our debt obligations and short-term investment portfolio. Our debt obligations include variable-rate instruments, which have exposure to changes in interest rates. ThisIn order to mitigate the risk of interest rate fluctuations, we have a number of interest rate swaps that fix the interest rates on certain existing variable-rate debt agreements. Our exposure to interest rate variability is somewhatfurther mitigated through our variable-rate investment portfolio. A hypothetical 10% change in the average interest rates incurred on average variable-rate debt held during 20152016 would have correspondingly changechanged our net earnings and cash flows associated with these items by less than $1$2 million. In order to help mitigate the risk of interest rate fluctuations, we have fixed the interest rates on certain existing variable-rate debt agreements. Our variable-rate debt is approximately 24%61% and 24% of our total long-term debt atas of December 31, 20152016 and December 31, 20142015., respectively.

We also have investments in marketable securities, which are exposed to market risk associated with changes in interest rates. If short-term interest rates were to average 1% more than they did in 20152016, interest income would increase by approximately $14$15 million.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
Alaska Air Group, Inc.
December 31, 2015
NOTE 1. GENERAL AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Organization and Basis of Presentation
 
The consolidated financial statements include the accounts of Alaska Air Group, Inc. (Air Group, or the Company)Company, and its primary subsidiaries, Alaska, Airlines, Inc. (Alaska)Horizon and, Horizon Air Industries, Inc. (Horizon), through which thestarting December 14, 2016, Virgin America. The Company conducts substantially all of its operations.operations through these subsidiaries. All significant intercompany balances and transactions have been eliminated. These financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America and their preparation requires the use of management’s estimates. Actual results may differ from these estimates.

Certain reclassifications have been made to prior year financial statements to conform to classifications used in the current year.

Cash and Cash Equivalents
 
Cash equivalents consist of highly liquid investments with original maturities of three months or less, such as money market funds, commercial paper and certificates of deposit. They are carried at cost, which approximates market value. The Company reduces cash balances when funds are disbursed. Due to the time delay in funds clearing the banks, the Company normally maintains a negative balance in its cash disbursement accounts, which is reported as a current liability. The amount of the negative cash balance was $1215 million and $712 million at December 31, 20152016 and 20142015, respectively, and is included in accounts payable, with the change in the balance during the year included in other financing activities in the consolidated statements of cash flows.

The Company hasCompany's restricted cash balances are primarily used to guarantee various letters of credit, self-insurance programs or other contractual rights. Restricted cash consists of highly liquid securities with original maturities of three months or less. They are carried at cost, which approximates fair value.

Marketable Securities

Investments with original maturities of greater than three months and remaining maturities of less than one year are classified as short-term investments. Investments with maturities beyond one year may be classified as short-term based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. All cash equivalents and short-term investments are classified as available-for-sale and realized gains and losses are recorded using the specific identification method. Changes in market value, excluding other-than-temporary impairments, are reflected in accumulated other comprehensive loss (AOCL)("AOCL").

Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. The Company uses a systematic methodology that considers available quantitative and qualitative evidence in evaluating potential impairment. If the cost of an investment exceeds its fair value, management evaluates, among other factors, general market conditions, credit quality of debt instrument issuers, the duration and extent to which the fair value is less than cost, ourthe Company's intent and ability to hold, or plans to sell, the investment. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded to Other-netOther—net in the consolidated statements of operations and a new cost basis in the investment is established.

Receivables
 
Receivables are due on demand and consist primarily of airline traffic (including credit card) receivables, Mileage Plan™ partners,partner receivables, amounts due from other airlines related to interline agreements, government tax authorities and other miscellaneous amounts due to the Company, and are net of an allowance for doubtful accounts. Management determines the allowance for doubtful accounts based on known troubled accounts and historical experience applied to an aging of accounts.


47




Inventories and Supplies—net
 
Expendable aircraft parts, materials and supplies are stated at average cost and are included in inventories and suppliesnet. An obsolescence allowance for expendable parts is accrued based on estimated lives of the corresponding fleet type and salvage values. The allowance for all non-surplus expendable inventories was $3736 million and $3437 million at December 31, 20152016 and 20142015, respectively. Inventory and suppliesnet also includes fuel inventory of $1416 million and $2114 million at December 31, 20152016 and 20142015, respectively. Repairable and rotable aircraft parts inventories are included in flight equipment.
 
Property, Equipment and Depreciation
 
Property and equipment are recorded at cost and depreciated using the straight-line method over their estimated useful lives less an estimated salvage value, which are as follows:
Aircraft and related flight equipment: 
Boeing 737 and Airbus 319/320 aircraft2020-25 years
Bombardier Q400 aircraft15 years
Buildings25-3025 - 30 years
Minor building and land improvements10 years
Capitalized leases and leasehold improvements
ShorterGenerally shorter of lease term or
estimated useful life
Computer hardware and software3-53-10 years
Other furniture and equipment5-10 years

Salvage values used for aircraft are 10% of the fair value, but as aircraft near the end of their useful lives, we updatemanagement updates the salvage value estimates based on current market conditions and expected use of the aircraft. “Related flight equipment” includes rotable and repairable spare inventories, which are depreciated over the associated fleet life unless otherwise noted.

Beginning October 1, 2016, the Company changed its accounting estimate for the expected useful life of the B737 NextGen aircraft, which includes the B737-700, -800, -900, -900ER aircraft and the related parts, from 20 years to 25 years. The change in estimate was precipitated by management's annual accounting policy review, which considered market studies, asset performance and intended use, as well as industry benchmarking. The change in estimate was applied prospectively effective October 1, 2016. The impact of this change in estimate in 2016 is a $17 million decrease to depreciation and amortization expense.
 
Capitalized interest, is based on the Company’s weighted-average borrowing rate, is added to the cost of the related asset, and is depreciated over the estimated useful life of the asset.

Maintenance and repairs other than engine maintenance on some B737-700 and -900 engines, are expensed when incurred. Major modifications that extend the life or improve the usefulness of aircraft are capitalized and depreciated over their estimated period of use. Maintenance on some B737-700 and -900 engines is covered under power-by-the-hour agreements with third parties, whereby the Company pays a determinable amount, and transfers risk, to a third party.  The Company expenses the contract amounts based on engine usage.
 
The Company evaluates long-lived assets to be held and used for impairment whenever events or changes in circumstances indicate that the total carrying amount of an asset or asset group may not be recoverable. The Company groups assets for purposes of such reviews at the lowest level, forat which identifiable cash flows of the asset group are largely independent of the cash flows of other groups of assets and liabilities. An impairment loss is considered when estimated future undiscounted cash flows expected to result from the use of the asset or asset group and its eventual disposition are less than its carrying amount. If the asset or asset group is not considered recoverable, a write-down equal to the excess of the carrying amount over the fair value will be recorded.
 
Goodwill

Goodwill represents the excess of purchase price over the fair value of the related net assets acquired in the Company's acquisition of Virgin America and is not amortized. As of December 31, 2016 the goodwill balance, based on a provisional purchase price allocation, was $1.9 billion. No goodwill impairment test occurred in 2016, as the acquisition was completed late in the fourth quarter. In future periods, the Company will review goodwill for impairment at least annually, or more frequently if events or circumstances indicate than an impairment may exist. The Company will perform this impairment at the reporting unit level. If fair value of the reporting unit exceeds the carrying amount, an impairment charge may be recorded.



Intangible Assets

Intangible assets as of December 31, 2016 were recorded as a result of the acquisition of Virgin America, and consist primarily of indefinite-lived airport slots, finite-lived airport gates and finite-lived customer relationships. Finite-lived intangibles are amortized over their estimated useful lives. Indefinite-lived intangibles are not amortized but are tested at least annually for impairment using a similar methodology to property, equipment and goodwill as described above.

Internally Used Software Costs
 
The Company capitalizes costs to develop internal-use software that are incurred in the application development stage. Amortization commences when the software is ready for its intended use and the amortization period is the estimated useful life of the software, generally three to five years. Capitalized costs primarily include contract labor and payroll costs of the individuals dedicated to the development of internal-use software.
 
Deferred Revenue
 
Deferred revenue results primarily from the sale of Mileage Plan™ miles and Elevate® points to third-parties. ThisIt also includes the liability for Elevate® flown points outstanding at the acquisition date that was recorded at its estimated fair value as part of purchase price accounting. The related revenue is recognized when award transportation is provided or over the term of the applicable agreement.

Operating Leases
 
The Company leases aircraft, airport and terminal facilities, office space and other equipment under operating leases. Some of these lease agreements contain rent escalation clauses or rent holidays. For scheduled rent escalation clauses during the lease terms or for rental payments commencing at a date other than the date of initial occupancy, the Company records minimum rental expenses on a straight-line basis over the terms of the leases in the consolidated statements of operations.
 
Leased Aircraft Return Costs
 
Cash payments associated with returning leased aircraft are accrued when it is probable that a cash payment will be made and that amount is reasonably estimable.estimable, usually no sooner than after the last scheduled maintenance event prior to lease return. Any accrual is based on the time remaining on the lease, planned aircraft usage and the provisions included in the lease agreement, although the actual amount due to any lessor upon return willmay not be known with certainty until lease termination.

As leased aircraft are returned, any payments are charged against the established accrual. The accrual is part of other current and long-term liabilities and was $5 million and $1 millionnot material as of December 31, 20152016 and December 31, 20142015, respectively.. The expense is included in Aircraft maintenance in the consolidated statements of operations.

Revenue Recognition
 
Passenger revenue is recognized when the passenger travels. Tickets sold but not yet used are reported as air traffic liability until travel or date of expiration. Air traffic liability includes approximately $4262 million and $3342 million related to credits for future travel, as of December 31, 20152016 and December 31, 20142015, respectively. These credits are recognized into revenue either when the passenger travels or at the date of expiration, which is twelve months from issuance. Commissions to travel agents and related fees are expensed when the related revenue is recognized. Passenger traffic commissions and related fees not yet recognized are includedrecorded as a prepaid expense. Taxes collected from passengers, including transportation excise taxes, airport and security fees and other fees, are recorded on a net basis within passenger revenue in the consolidated statements of operations. Due to complex pricing structures, refund and exchange policies, and interline agreements with other airlines, certain amounts are recognized as revenue using estimates regarding both the timing of the revenue recognition and the amount of revenue to be recognized. These estimates are based on the Company’s historical data.

Freight and mail revenues are recognized when service isthe related services are provided.

Other - Other—net revenues are primarily related to the Mileage Plan™ and theyElevate® programs. They are recognized as described in the “Mileage Plan”“Frequent Flyer Programs” paragraph below. Other - Other—net also includes certain ancillary or non-ticket revenues, such as checked-bag fees, reservations fees, ticket change fees, on-board food and beverage sales, and, to a much lesser extent, commissions from car and hotel vendors and from the sales of travel insurance. These items are recognized as revenue when the related services are provided.  Airport lounge memberships are recognized as revenue over the membership period.

Mileage Plan
Frequent Flyer Programs
 
Alaska operates athe Mileage Plan™ frequent flierflyer program, (“Mileage Plan™”) that providesand Virgin America operates the Elevate® frequent flyer program. Both programs provide travel awards to members based on accumulated mileage.mileage or points. For miles or points earned by flying on Alaska or Horizonthe Company's airlines and through airline partners, the estimated cost of providing award travel is recognized as a selling expense and accrued as a liability, as miles are earned and accumulated.

Alaska and Virgin America also sellssell services, including miles or points for transportation, to non-airline partners, such as hotels, car rental agencies and a major bankbanks that offers Alaska Airlinesoffer Alaska's and Virgin America's affinity credit cards. The Company defers passenger revenue related to air transportation and certificates for discounted companion travel until the transportation is delivered. The deferred proceeds are recognized as passenger revenue for awards redeemed and flown on Alaska or Horizon,the Company's airlines and as Other-netOther—net revenue for awards redeemed and flown on other airlines (less the cost paid to the other airlines based on contractual agreements). For theThe elements that represent use of the Alaska Airlines brandand Virgin America brands and access to frequent flierflyer member lists and advertising it isare recognized as commission income in the period that those elements are sold and included in Other - Other—net revenue in the consolidated statements of operations.

Derivative Financial Instruments
 
The Company's operations are significantly impacted by changes in aircraft fuel prices and interest rates. In an effort to manage our exposure to these risks, the Company periodically enters into fuel and interest rate derivative instruments. These derivative instruments are recognized at fair value on the balance sheet and changes in the fair value isare recognized in AOCL or in the consolidated statements of operations, depending on the nature of the instrument.

The Company does not hold or issue derivative fuel hedge contracts for trading purposes and does not apply hedge accounting. For cash flow hedges related to our interest rate swaps, the effective portion of the derivative represents the change in fair value of the hedge that offsets the change in fair value of the hedged item. To the extent the change in the fair value of the hedge does


not perfectly offset the change in the fair value of the hedged item, the ineffective portion of the hedge is immediately recognized in interest expense.
 
Fair Value Measurements

Accounting standards define fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The standards also establish a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:

Level 1 - Quoted prices in active markets for identical assets or liabilities.


50




Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
The Company has elected not to use the Fair Value Optionfair value option provided in the accounting standards for non-financial instruments, and accordinglyinstruments. Accordingly, those assets and liabilities are carried at amortized cost. For financial instruments, thosethe assets and liabilities are carried at fair value, and arewhich is determined based on the market approach or income approach, depending upon the level of inputs used.

Assets and liabilities recognized or disclosed at fair value on a nonrecurring basis include items such as property, plant and equipment, goodwill, intangible assets and certain other assets and liabilities. The Company determines the fair value of these items using Level 3 inputs, as described in Note 2 and Note 5.

Income Taxes
 
The Company uses the asset and liability approach for accounting for and reporting income taxes. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. A valuation allowance would be established, if necessary, for the amount of any tax benefits that, based on available evidence, are not expected to be realized. As of December 31, 2016, there is a partial valuation allowance against net deferred tax assets. The Company accounts for unrecognized tax benefits in accordance with the applicable accounting standards.

Virgin America has substantial federal and state net operating losses ("NOLs") for income tax purposes. The Company's ability to utilize Virgin America's NOLs could be limited if Virgin America had an “ownership change,” as defined in Section 382 of the Internal Revenue Code and similar state provisions. In general terms, an ownership change can occur whenever there is a collective shift in the ownership of a company by more than 50% by one or more “5% stockholders” within a three-year period. The occurrence of such a change generally limits the amount of NOL carryforwards a company could utilize in a given year to the aggregate fair market value of the company's common stock immediately prior to the ownership change, multiplied by the long-term tax-exempt interest rate in effect for the month of the ownership change. The acquisition constituted an ownership change and the potential for further limitations following the acquisition. See Note 7 to the consolidated financial statements for more discussion of the calculation.
 
Stock-Based Compensation
 
Accounting standards require companies to recognize as expense the fair value of stock options and other equity-based compensation issued to employees as of the grant date. These standards apply to all stock awards that the Company grants to employees as well as the Company’s Employee Stock Purchase Plan (ESPP)("ESPP"), which features a look-back provision and allows employees to purchase stock at a 15% discount. All stock-based compensation expense is recorded in wages and benefits in the consolidated statements of operations.



Earnings Per Share (EPS)

Diluted EPS is calculated by dividing net income by the average common shares outstanding plus additional common shares that would have been outstanding assuming the exercise of in-the-money stock options and restricted stock units, using the treasury-stock method. In 20152016, 20142015, and 20132014, antidilutive stock options excluded from the calculation of EPS were not material.

Recently Issued Accounting Pronouncements

In May 2014, the FASBFinancial Accounting Standards Board ("FASB") issued Accounting StandardStandards Update ("ASU") 2014-09, "Revenue from Contracts with Customers" (ASU 2014-09)(Topic 606), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASUThis comprehensive new standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In March 2016, the FASB issued ASU 2016-08, "Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations" to clarify the guidance on determining whether the Company is considered the principal or the agent in a revenue transaction where a third party is providing goods or services to a customer. Entities are permitted to use either a full retrospective or cumulative effect transition method, and are required to adopt all parts of the new revenue standard using the same transition method. The new standard is effective for the Company on January 1, 2018. The standard permits the use of either the retrospective or cumulative effect transition method. At this time, the Company believes the most significant impact to the financial statements will be into Mileage PlanPlan™ revenues and liabilities. The Company currently uses the incremental cost approach for miles earned through travel. ThisAs this approach will be eliminated with the standard, eliminates that option and the Company will be required to significantly increase its liability for earned miles through a relative selling price model. The Company has not evaluatedcontinues to evaluate and model the full impact of the standard although applicationand currently plans to apply the full retrospective transition method.

In April 2015, the FASB issued ASU 2015-03, "Interest—Imputation of Interest" (Subtopic 835-30), which requires debt issuance costs related to a debt liability be presented as a direct deduction from the carrying value of the debt liability. The amendment was adopted as of January 1, 2016. Prior period debt balances have been adjusted to reflect the adoption of the ASU. The adoption of the ASU had no impact on the statements of operations or retained earnings.

In February 2016, the FASB issued ASU 2016-02, "Leases" (Topic 842), which requires lessees to recognize assets and liabilities for leases currently classified as operating leases. Under the new standard a lessee will recognize a liability on the balance sheet representing the lease payments owed, and a right-of-use-asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is expectedpermitted to result inmake an accounting policy election not to recognize lease assets and lease liabilities. The new standard is effective for the Company on January 1, 2019. Early adoption of the standard is permitted. At this time, the Company believes the most significant impact to the financial statements will relate to the recording of a material increaseright of use asset associated with leased aircraft. Other leases, including airports and real estate, equipment, software and other miscellaneous leases continue to Deferred Revenue.be assessed for impact as it relates to ASU 2016-02. The Company has not yet selected a transition method.determined whether it will early adopt the standard.

In July 2015,March 2016, the FASB issued ASU 2015-07, Disclosures2016-09, "Compensation—Stock Compensation" (Topic 718), which simplifies several aspects of accounting for Investmentsemployee share-based payment awards, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in Certain Entitiesthe statement of cash flows. The ASU is effective for the Company beginning January 1, 2017. The adoption of the standard will not have a material impact on the Company's statements of operations or financial position.

In January 2017, the FASB issued ASU 2017-04, "Intangibles—Goodwill and Other" (Topic 350), which eliminates step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that Calculate Net Asset Value pergoodwill. The ASU is effective for the Company beginning January 1, 2019. Early adoption of the standard is permitted. Beginning in fiscal 2017 the Company will be required to perform an impairment test for goodwill arising from its acquisition of Virgin America and plans to adopt the standard in 2017.

NOTE 2. ACQUISITION OF VIRGIN AMERICA INC.

Virgin America

On December 14, 2016, the Company acquired 100% of the outstanding common shares and voting interest of Virgin America. Virgin America offers scheduled air transport throughout the United States and Mexico primarily from its focus cities of Los Angeles, San Francisco and, to a lesser extent, Dallas Love Field, to other major business and leisure destinations in North America. The Company believes the acquisition of Virgin America will provide broader national reach and position the Company to better serve people living on the West Coast. The combined airline will provide 1,200 daily departures to its guests, leveraging Alaska's strength in the Pacific Northwest with Virgin America's strength in California. The Company believes that combining loyalty programs and networks will provide greater benefits for its guests and expand its international partner portfolio, giving guests an even more expansive global reach.

The results of Virgin America have been included in the consolidated financial statements since the acquisition date. For the year ended December 31, 2016, revenue and net income from Virgin America recognized in the Company's consolidated results of operations were $99 million and $15 million.

Fair value of consideration transferred

The fair value of consideration transferred on the closing date includes the value of the cash consideration and accelerated and vested equity awards attributable to pre-acquisition service. The purchase price is as follows (in millions, except per-share stock price):

Cash consideration paid for common stock issued and outstanding2,545
Accelerated and vested equity awards attributable to pre-acquisition service51
Total Purchase Price$2,596

Fair values of the assets acquired and the liabilities assumed

The transaction has been accounted for as a business combination using the acquisition method of accounting, which removesrequires, among other things, that assets acquired and liabilities assumed be recognized on the requirement for companiesbalance sheet at their fair values as of the acquisition date. The fair values of the assets acquired and liabilities assumed were determined using the market, income and cost approaches. The purchase price allocation was prepared on a preliminary basis and is subject to disclosefurther adjustments as additional information becomes available concerning the fair value hierarchyof the assets acquired and liabilities assumed. The Company expects to continue obtaining information to assist it with determining the fair values of the net assets acquired during the measurement period. Any adjustments to the purchase price allocation will be made as soon as practicable but no later than one year from the acquisition date.

Intangible Assets

Of the $143 million of acquired intangible assets, $89 million was provisionally assigned to airport slots. Airport slots are rights to take-off or land at a slot-controlled airport during a specific time period and are a means by which the FAA manages airspace/airport congestion. The Company acquired slots at three such airports—John F. Kennedy International, LaGuardia and Ronald Reagan Washington National. These slots either have no expiration dates or are expected to be renewed indefinitely in line with the FAA's past practice. They require no maintenance and do not have an established residual value. As the demands for air travel at these airports have remained very strong, the Company expects to use these slots in perpetuity and has determined these airport slots to be indefinite-lived intangible assets. They will not be amortized but rather tested for impairment annually, or more frequently when events and circumstances indicate that impairment may exist.

Of the remaining $54 million, $40 million was provisionally assigned to customer relationships to be amortized on a straight-line basis over the estimated economic life of eight years and $14 million to airport gates to be amortized on straight-line basis over the remaining lease term of twelve years. As noted above, the fair value of the acquired identifiable intangible assets calculatedis provisional pending results of their final valuation.

The Company considered examples of intangible assets that the FASB believes meet the criteria for recognition apart from goodwill, as well as any other intangible assets common to the airline industry, and did not identify any other such intangible assets acquired in the transaction.

Goodwill

Goodwill of $1.9 billion represents the excess of the purchase price over the fair value of the underlying net assets acquired and largely results from expected future synergies from combining operations as well as an assembled workforce, which does not qualify for separate recognition. Goodwill is not amortized to earnings, but instead is reviewed for impairment at net asset valueleast annually, absent any indicators of impairment.

Repayment of related-party debt and merger-related costs

Soon after the acquisition, the Company repaid $55 million of related-party debt held by Virgin America as of December 14, 2016 forto comply with the Company. However, early adoption is permitted andchange-of-control provision triggered by the transaction.

As of December 31, 2016, the Company has electedincurred pretax merger-related costs of $117 million. Costs classified as merger-related are directly attributable to adopt this standardmerger activities. These costs are classified as "Special items—merger-related costs and other" within the Statement of Operations. Refer to Note 11 for further information on special items. The Company expects to continue to incur merger-related costs in the future as the integration continues.

NOTE 3.4. DERIVATIVE INSTRUMENTS AND RISK MANAGEMENT

Fuel Hedge Contracts

The Company’s operations are inherently dependent upon the price and availability of aircraft fuel. To manage economic risks associated with fluctuations in aircraft fuel prices, the Company periodically enters into call options for crude oil.

As of December 31, 20152016, the Company had fuel hedge contracts outstanding covering 273394 million gallons of crude oil that will be settled from January 20162017 to June 20172018. Refer to the contractual obligations and commitments section of Item 7 for further information.

Interest Rate Swap Agreements

The Company is exposed to market risk from adverse changes in variable interest rates on long term debt and certain aircraft lease agreements. To manage this risk, the Company periodically enters into interest rate swap agreements. As of December 31, 2016, the Company has outstanding interest rate swap agreements with a third party designed to hedge the volatility of the underlying variable interest rate in the Company's aircraftrates on lease agreements for six Boeing 737-800 aircraft. TheB737-800 aircraft, as well as two interest rate swap agreements with third parties designed to hedge the volatility of the underlying variable interest rates on $295 million of the debt obtained in 2016. All of the interest rate swap agreements stipulate that the Company pay a fixed interest rate and receive a floating interest rate over the term of the contractunderlying contracts. The interest rate swap agreements expire from February 2020 through March 2021 to coincide with the lease termination dates and receive a floating interest rate.October 2022 through September 2026 to coincide with the debt maturity dates. All significant terms of the swap agreementagreements match the terms of the lease agreements, including interest-rate index,underlying hedged items, and have been designated as qualifying hedging instruments, which are accounted for as cash flow hedges.

No gains or losses related to interest rate swaps on variable rate debt have been recognized in interest expense during 2016. The amounts shown as recognized in OCI are prior to the losses recognized in aircraft rent during the period. The Company expects $54 million to be reclassified from OCI to aircraft rent and $1 million to interest expense within the next twelve months.

Credit Risk and Collateral

The Company is exposed to credit losses in the event of non-performance by counterparties to these derivative instruments. To mitigate exposure, the Company periodically reviews the risk of counterparty nonperformance by monitoring the absolute exposure levels and credit ratings. The Company maintains security agreements with a number of its counterparties which may require the Company to post collateral if the fair value of the selected derivative instruments fall below specified thresholds. The posted collateral does not offset the fair value of the derivative instruments and is included in "Prepaid expenses and other current assets" on the consolidated balance sheet.

The amount posted as collateral for these contracts is not material to the consolidated balance sheets as of December 31, 20152016, and 20142015.

The Company uses the market and income approach to determine the fair value of marketable securities. U.S. government securities are Level 1 as the fair value is based on quoted prices in active markets. Foreign government bonds, asset-backed securities, mortgage-backed securities, corporate notes and bonds, and municipal securities are Level 2 as the fair value is based on standard valuation models that are calculated based on observable inputs such as quoted interest rates, yield curves, credit ratings of the security and other observable market information.

The Company uses the market approach and the income approach to determine the fair value of derivative instruments. Fuel hedge contracts that are not traded on a public exchange are Level 2 as the fair value is primarily based on inputs which are readily available in active markets or can be derived from information available in active markets. The fair value for call options is determined utilizing an option pricing model based on inputs that are readily available in active markets, or can be derived from information available in active markets. In addition, the fair value considers the exposure to credit losses in the event of non-performance by counterparties. Interest rate swap agreements are Level 2 as the fair value of these contracts is determined based on the difference between the fixed interest rate in the agreements and the observable LIBOR-based interest forward rates at period end, multiplied by the total notional value.



The Company has no other financial assets that are measured at fair value on a nonrecurring basis at December 31, 2015.2016.

Fair Value of Other Financial Instruments

The Company used the following methods and assumptions to determine the fair value of financial instruments that are not recognized at fair value as described below.

Cash and Cash Equivalents: Carried at amortized costs which approximate fair value.

Debt: The carrying amounts of the Company's variable-rate debt approximate fair values. For fixed-rate debt, the Company uses the income approach to determine the estimated fair value, by discounting cash flows using borrowing rates for comparable debt over the weighted life of the outstanding debt. The estimated fair value of the fixed-rate debt is Level 3 as certain inputs used are unobservable.

During 20152016, the Company's total debt increased $2.3 billion, primarily due to the addition of $2.0 billion of secured debt financing from multiple lenders to fund the acquisition of Virgin America. Approximately $1.6 billion of the loans are secured by a total of 56 aircraft, including 37 B737-900ER aircraft and 19 B737-800 aircraft. An additional $400 million is secured by Air Group's interest in certain aircraft purchase agreements. The remainder is due to assumed debt from Virgin America. During 2016, the Company issued no new debt and made scheduled debt payments of $116 million.$249 million, including $95 million of debt extinguishment that arose from the Virgin America acquisition, and $12 million related to prepayments of existing loans. The Company's variable-rate notes payable 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, 20152016, none of the Company's borrowings were restricted by financial covenants.

The Company has two $100 million credit facilities and one $52 million credit facility. All three facilities have variable interest rates based on LIBOR plus a specified margin. One of the $100 million facilities, which expires in September 2017, is secured by aircraft. The other $100 million facility, which expires in March 2017, is secured by certain accounts receivable, spare engines, spare parts and ground service equipment. The $52 million facility expires in October 20162017 with a mechanism for annual renewal and is secured by two 737-800 aircraft. The Company has secured letters of credit against the $52 million facility, but has no immediate plans to borrow using anyeither of thesethe two remaining facilities. All three credit facilities have a requirement to maintain a minimum unrestricted cash and marketable securities balance of $500 million. The Company was in compliance with this covenant at December 31, 20152016.

NOTE 6.7. INCOME TAXES

Deferred Income Taxes

Deferred income taxes reflect the impact of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and such amounts for tax purposes. Primarily due to differences in depreciation rates for federal income tax purposes and for financial reporting purposes, the Company has generated a net deferred tax liability.

Changes in net deferred tax liabilities resulted from 2016 activity and the acquisition of Virgin America.

At December 31, 2016, as a result of the acquisition of Virgin America, discussed in Note 2, Virgin America had federal NOLs of approximately $773 million that expire beginning in 2028 and continuing through 2036, and state NOLs of approximately $344 million that expire beginning in 2027 and continuing through 2035.



Virgin America has experienced multiple “ownership changes” as defined in Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), the most recent being its acquisition by the Company. Section 382 of the Code imposes an annual limitation on the amount of pre-ownership change NOLs of the corporation that experiences an ownership change. The limitation imposed by Section 382 of the Code for any post-ownership change year generally would be determined by multiplying the value of such corporation’s stock immediately before the ownership change by the applicable long-term tax-exempt rate. Any unused annual limitation may, subject to certain limits, be carried over to later years, and the limitation may, under certain circumstances, be increased by built-in gains or reduced by built-in losses in the assets held by such corporation at the time of the ownership change. The combined company’s use of NOLs generated after the date of an ownership change would not be limited unless the combined company were to experience a subsequent ownership change.

The combined company’s ability to use the NOLs will also depend on the amount of taxable income generated in future periods. The NOLs may expire before the combined company can generate sufficient taxable income to utilize the NOLs.

Valuation allowances are provided to reduce the related deferred income tax assets to an amount which will, more likely than not, be realized. The Company has determined it is more likely than not that a portion of the state NOL carryforward will not be realized and, therefore, has provided a valuation allowance of $4 million for that portion. The Company has likewise concluded that it is more likely than not that all of its federal and the remaining state deferred income tax assets will be realizablerealized and thus no additional valuation allowance has been recorded as of December 31, 2015. This conclusion is based on the expected future reversals of existing taxable temporary differences, anticipated future taxable income, and the potential for future tax planning strategies to generate taxable income, if needed.recorded. The Company will continue to reassessreassesses the need for a valuation allowance during each future reporting period.

In 2016, the Company incurred $39 million of acquisition-related costs that are not deductible under U.S. federal tax law. These expenses are included in Special items—merger-related costs and other on the Company’s consolidated statement of operations


for the year ended December 31, 2016 and are reflected as a permanent unfavorable adjustment for the year ended December 31, 2016, in the table above.

In the fourth quarter of 2015, the Company filed amended state tax returns for the years 2010 through 2013 to updatechange the Company’s position on income sourcing in various states. These positions were also taken on 2014 and future filings, and will be taken going forward.unless guidance or rules changed. In 2016, adjustments were made to the Company's position on income sourcing in various states due to updated guidance from state taxing authorities.

NOTE 7.8. EMPLOYEE BENEFIT PLANS
 
Four defined-benefit and five defined-contribution retirement plans cover various employee groups of Alaska and Horizon. Following the acquisition of Virgin America on December 14, 2016, there is a sixth defined contribution plan which covers the Virgin America employee groups. The defined-benefit plans provide benefits based on an employee’s term of service and average compensation for a specified period of time before retirement. The qualified defined-benefit pension plans are closed to new entrants.
 
Accounting standards require recognition of the overfunded or underfunded status of an entity’s defined-benefit pension and other postretirement plan as an asset or liability in the consolidated financial statements and requires recognition of the funded status in AOCL.
 
Qualified Defined-Benefit Pension Plans

The Company’s pension plans are funded as required by the Employee Retirement Income Security Act of 1974 (ERISA).1974. The defined-benefit plan assets consist primarily of marketable equity and fixed-income securities. The Company uses a December 31 measurement date for these plans.

The discount rate wasrates are determined using current rates earned on high-quality, long-term bonds with maturities that correspond with the estimated cash distributions from the pension plans. At December 31, 20152016, the Company selected discount rates for each of the plans using a pool of higher-yielding bonds estimated to be more reflective of settlement rates, as management has taken steps to ultimately terminate or settle plans that are frozen and move toward freezing benefits in active plans in the future. In determining the expected return on plan assets, the Company assesses the current level of expected returns on risk-free investments (primarily government bonds), the historical level of the risk premium associated with the other asset classes in which the portfolio is invested and the expectations for future returns of each asset class. The expected return for each asset class is then weighted based on the target asset allocation to develop the expected long-term rate of return on assets assumption for the portfolio.

Plan assets are invested in common commingled trust funds invested in equity and fixed income securities and in certain real estate assets. The target and actual asset allocation of the funds in the qualified defined-benefit plans, by asset category, isare as follows: 
2015 2014Target 2016 2015

The Company’s investment policy focuses on achieving maximum returns at a reasonable risk for pension assets over a full market cycle. In 2015, the Company separated the management of plan assets for the defined-benefit plan that covers the Company's non-union, management participants. This plan has been closed to new participants for several yearssince 2003 and benefits were frozen effective January 1, 2014. These assets have a higher allocation to fixed income securities than the other plans. The Company uses a fund manager and invests in various asset classes to diversify risk.

Target allocations for the primary asset classes based on current funded status are approximately: 
Domestic equities:21% - 33%
Non-U.S. equities:7% - 17%
Fixed income:48% - 67%
Real estate:0% - 8%
The Company determines the strategic allocation between equities, fixed income and real estate based on current funded status and other characteristics of the plans. As the funded status improves, the Company increases the fixed income allocation of the portfolio and decreases the equity allocation. Actual asset allocations are reviewed regularly and periodically rebalanced as appropriate.
As of December 31, 20152016, all assets other than real estate were invested in common commingled trust funds.  The Company uses the net asset values of these funds to determine fair value as allowed using the practical expediency method outlined in the accounting standards. Fair value estimates for real estate are calculated using the present value of expected future cash flows based on independent appraisals, local market conditions and current and projected operating performance.

Certain investments were previously misclassified in the fair value hierarchy disclosure in 2015 based on the Company's interpretation of relevant guidance.  Upon further evaluation, investments in common commingled trusts were determined to


have a readily determinable fair value and are now disclosed within the fair value hierarchy. Additionally, investments in the real estate limited partnership are measured at net asset value per share as a practical expedient and excluded from the fair value hierarchy.  These changes in disclosure do not have a material impact on the financial statements and are consistent with presentation of amounts as of December 31, 2016 as shown below.

In 2015, the Company recognized a settlement charge of $14 million related to lump sum settlements offered to terminated, vested plan participants. The result was a reduction in the projected benefit obligation of $62 million. The settlement charge reflects the remaining unamortized actuarial loss in AOCL associated with the settled obligation.

There are no current statutory funding requirements for the Company’s plans in 20162017, nor does the Company expect to contribute to the qualified defined-benefit pension plans during 20162017.

Nonqualified Defined-Benefit Pension Plan
 
Alaska also maintains an unfunded, noncontributory defined-benefit plan for certain elected officers. This plan uses a December 31 measurement date. The assumptions used to determine benefit obligations and the net period benefit cost for the nonqualified defined-benefit pension plan are similar to those used to calculate the qualified defined-benefit pension plan. The plan's unfunded status, PBO and accumulated benefit obligation isare immaterial. The net pension expense in prior year and expected future expense is also immaterial.



Postretirement Medical Benefits
 
The Company allows certain retirees to continue their medical, dental and vision benefits by paying all or a portion of the active employee plan premium until eligible for Medicare, currently age 65. This results in a subsidy to retirees, because the premiums received by the Company are less than the actual cost of the retirees’ claims. The accumulated postretirement benefit obligation (APBO) for this subsidy is unfunded. The accumulated postretirement benefit obligation was $64$76 million and $81$64 million at December 31, 20152016 and 2014,2015 respectively. The net periodic benefit cost was not material to the statement of operations.in 2016 or 2015.

During 2014, the Company made changes to the postretirement medical benefits for non-union personnel and certain labor groups to sunset the postretirement medical benefits effective in 2015. As a result of these changes, the Company recognized a partial curtailment gain of $25 million in 2014. The curtailment gain included $5 million associated with an embedded sick leave subsidy. This subsidy was used to establish a new compensated absence liability. The net impact of the curtailment gain of $20 million is included in special items in the income statement.

Defined-Contribution Plans
 

62




The defined-contribution plans are deferred compensation plans under section 401(k) of the Internal Revenue Code. All of these plans require Company contributions. Total expense for the defined-contribution plans was $6067 million, $60 million and $54 million in 2016, 2015, and $44 million in 2015, 2014, and 2013, respectively..  
 
The Company also has a noncontributory, unfunded defined-contribution plan for certain elected officers of the Company who are ineligible for the nonqualified defined-benefit pension plan. Amounts recorded as liabilities under the plan are not material to the consolidated balance sheetsheets at December 31, 20152016 and 2014.2015.

Pilot Long-term Disability Benefits

Alaska maintains a long-term disability plan for its pilots. The long-term disability plan does not have a service requirement. Therefore, the liability is calculated based on estimated future benefit payments associated with pilots that were assumed to be disabled on a long-term basis as of December 31, 20152016 and does not include any assumptions for future disability. The liability includes the discounted expected future benefit payments and medical costs.  The total liability was $1925 million and $1619 million, which was recorded net of a prefunded trust account of $23 million and $2 million, and included in long-term other liabilities on the consolidated balance sheets as of December 31, 20152016 and December 31, 2014,2015, respectively.

Employee Incentive-Pay Plans
 
Alaska and Horizon haveThe Company has employee incentive plans that pay employees based on certain financial and operational metrics. These metrics are set and approved annually by the Compensation Committee of the Board of Directors. The aggregate expense under these plans in 20152016, 2015 and 2014 was 2014$127 million and 2013 was, $120 million, and $116 million, and $105 million, respectively.. The Air Group plans are summarized below:below.
 
Performance-Based Pay (PBP)("PBP") is a program that rewards allthe majority of Air Group employees.  The program is based on four separate metrics related to Air Group profitability, safety, achievement of unit-cost goals and employee engagement as measured by customer satisfaction.

The Operational Performance Rewards Program entitles allthe majority of Air Group employees to quarterly payouts of up to $300 per person if certain operational and customer service objectives are met.

Virgin America operated three similar plans, including a traditional profit sharing plan, through 2016. The impact of these plans was immaterial for the period from the date of acquisition through December 31, 2016. Starting January 1, 2017 all employees will participate in the Air Group plans described above.

Capacity Purchase Agreements (CPAs)("CPAs")
 
At December 31, 20152016, Alaska had CPAs with three carriers, including the Company's wholly-owned subsidiary, Horizon. Horizon sells 100% of its capacity under a CPA with Alaska. In addition, Alaska has a CPACPAs with PenAirSkyWest Airlines, Inc ("SkyWest") to fly certain routes in the Lower 48 and Canada and with Peninsula Airways, Inc ("PenAir") to fly certain routes in the state of Alaska. Under these agreements, Alaska pays the carriers an amount which is based on a determination of their cost of operating those flights and other factors intended to approximate market rates for those services. Future payments (excluding Horizon) are based on minimum levels of flying by the third-party carriers, which could differ materially due to variable payments based on actual levels of flying and certain costs associated with operating flights such as fuel.

DuringAircraft Maintenance Deposits

The Company is contractually required to make maintenance deposit payments to aircraft lessors, which represent maintenance reserves made solely to collateralize the second quarter Alaska signedlessor for future maintenance events should the Company not perform required maintenance. Under most leases, the lease agreements provide that maintenance reserves are reimbursable upon completion of the major maintenance event in an amendmentamount equal to the CPA with SkyWest to removelesser of (i) the eight CRJ-700 aircraft out of regional operations and replace them with eight E175 aircraft. Six of these CRJ-700 aircraft are leasedamount qualified for reimbursement from maintenance reserves held by the lessor associated with the specific major maintenance event or (ii) the qualifying costs related to the specific major maintenance event.

Aircraft Maintenance and Parts Management

The E175 aircraft will be introduced into service throughout 2016, at which time the CRJ-700 aircraft will be removed from service. The CPA with SkyWest is a service contract that, in accordance with GAAP, includes embedded leases relatedagreement transfers certain risks to the third-party service provider. There


are minimum payments under this agreement, which are reflected in the table above. Accordingly, payments could differ materially based on actual aircraft operated under the agreement.utilization.

Contingencies
 
The Company is a party to routine litigation matters incidental to its business and with respect to which no material liability is expected. Liabilities for litigation related contingencies are recorded when a loss is determined to be probable and estimable.

In 2015, three flight attendants filed a class action lawsuit seeking to represent all Virgin America flight attendants for damages based on alleged violations of California and City of San Francisco wage and hour laws.  Plaintiffs received class certification in November 2016. Virgin America filed a motion for summary judgment seeking to dismiss all claims on various federal preemption grounds.  In January 2017, the Court denied in part and granted in part Virgin America’s motion.  Virgin America believes the claims in this case are without factual and legal merit and intends to defend this lawsuit through, among other strategies, filing a motion for reconsideration of the Court’s certification decision and denial of summary judgment and, if necessary, a motion for certification of interlocutory appeal to the U.S. Court of Appeals for the Ninth Circuit.

Management believes the ultimate disposition of these matters is not likely to materially affect the Company's financial position or results of operations. This forward-looking statement is based on management's current understanding of the relevant law and facts, and it is subject to various contingencies, including the potential costs and risks associated with litigation and the actions of arbitrators, judges and juries.

NOTE 10.11. SPECIAL ITEMS

Special Mileage Plan Revenue

In the third quarter of 2013,2016, the Company modifiedrecognized special items of $117 million for merger-related costs associated with its Affinity Card Agreement (Agreement) with Bankacquisition of America Corporation (BAC), through whichVirgin America. Costs classified as merger-related are directly attributable to merger activities. $39 million of these costs were not deductible under U.S. federal tax law, as discussed in Note 7. The Company also recognized a special tax expense of $17 million representing the Company sells miles and other itemsimpact of adjustments to BAC and the Company's loyalty program members accrue frequent flyer miles basedposition on purchases using credit cards issued by BAC. As a result of the execution of the Agreement, consideration received as part of this agreement is subject to Accounting Standards Update 2009-13, "Multiple-Deliverable Revenue Arrangements - a consensus of the FASB Emerging Issues Task Force" (ASU 2009-13).

The Company followed the rollforward transition approach of ASU 2009-13, which required that the Company's existing deferred revenue balance be adjusted to reflect the value, on a relative selling price basis, of any undelivered element remaining at the date of contract modification as if the Company had been applying ASU 2009-13 since inception of the Agreement. The relative selling price of the undelivered element (air transportation) is 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 Special mileage plan revenue. The amount recorded for the year ended December 31, 2013 was $192 million.

Also during 2013, as part of the Company's ongoing evaluation of Mileage Plan program assumptions, the Company performed a statistical analysis of historical data, which refined its estimate of the amount of breakageincome sourcing in the mileage population. This new refinement enables the Company to better identify historical differences between certain of its mileage breakage estimates and the amounts that have actually been experienced. As a result, the Company increased its estimate of the number of frequent flyer miles expected to expire unused from 12% to 17.4%. Included in the Special mileage plan revenue item above is $44 million of additional revenue related to the effect of the change on the deferred revenue balance.

Stock Awards
 
Restricted Stock Units (RSUs)("RSUs") are awarded to eligible employees and entitle the grantee to receive shares of common stock at the end of the vest period. The fair value of the RSUs is based on the stock price on the date of grant. The RSUs “cliff vest” after three years, or the period from the date of grant to the employee’s retirement eligibility, and expense is recognized accordingly. Performance Share Units (PSUs) are awarded to certain executives to receive shares of common stock if specific performance goals and market conditions are achieved. There are several tranches of PSUs which vest when performance goals and market conditions are met.

The Company’s management, with the participation of the Principal Executive Officer and Principal Financial Officer, conducted an evaluation of the effectiveness of the Company’s disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of the end of the period covered by this report. Based on that evaluation, the Principal Executive Officer and Principal Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this report.
 
CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING
 
ThereExcept as noted below, there have been no changes in the Company’s internal controls over financial reporting during the fourth quarter of 20152016 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.reporting except as noted below.

In the fourth quarter of 2016, the Company acquired Virgin America (see Note 2). As permitted by Securities and Exchange Commission Staff interpretive guidance for newly acquired businesses, management excluded Virgin America from its annual evaluation of internal control over financial reporting as of December 31, 2016. We have begun the process of assessing Virgin America’s internal controls over financial reporting and plan to incorporate Virgin America in our evaluation of internal controls over financial reporting in 2017. As of December 31, 2016, Virgin America’s total assets represented approximately 33% of the Company’s consolidated assets, and revenue represented approximately 2% of the Company’s consolidated operating revenues as of and for the year ended December 31, 2016.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
 
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the 2013 framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO Framework). Management's assessment of internal control over financial reporting as of December 31, 2016 excluded internal control over financial reporting related to Virgin America, acquired December 14, 2016, which represented approximately 33% of consolidated total assets and 2% of consolidated operating revenues as of and for the year ended December 31, 2016. Based on our evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 20152016.
 
We intend to regularly review and evaluate the design and effectiveness of our disclosure controls and procedures and internal control over financial reporting on an ongoing basis and to improve these controls and procedures over time and to correct any deficiencies that we may discover in the future. While we believe the present design of our disclosure controls and procedures and internal control over financial reporting are effective, future events affecting our business may cause us to modify our controls and procedures.
 
The Company's independent registered public accounting firm has issued an attestation report regarding its assessment of the effectiveness of the Company's internal control over financial reporting as of December 31, 20152016.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and ShareholdersStockholders
Alaska Air Group, Inc.:
We have audited Alaska Air Group, Inc.’s (the Company) internal control over financial reporting as of December 31, 2015,2016, based on criteria established in Internal Control - Integrated Framework (2013)(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Alaska Air Group, Inc.’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 Report on Internal Control over Financial Reporting (included in Item 9A). 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, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included 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, Alaska Air Group, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015,2016, based on criteria established in Internal Control - Integrated Framework(2013) (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
Alaska Air Group, Inc. acquired Virgin America Inc. (Virgin America) during 2016, and management excluded from its assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2016, Virgin America’s internal control over financial reporting associated with total assets that represented approximately 33% of the Company’s consolidated assets, and revenue that represented approximately 2% of the Company’s consolidated operating revenues included in the consolidated financial statements of the Company and subsidiaries as of and for the year ended December 31, 2016. Our audit of internal control over financial reporting of Alaska Air Group, Inc. also excluded an evaluation of the internal control over financial reporting of Virgin America.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Alaska Air Group, Inc. and subsidiaries as of December 31, 20152016 and 2014,2015, and the related consolidated statements of operations, comprehensive operations, shareholders’ equity, and cash flows for each of the years in the three-yearthree‑year period ended December 31, 2015,2016, and our report dated February 11, 201628, 2017 expressed an unqualified opinion on those consolidated financial statements.
