ITEM 1A. RISK FACTORS. The following risk factors should be read carefully when evaluating the Company's business and the forward-looking statements contained in this report and other statements the Company or its representatives make from time to time. Any of the following risks could materially and adversely affect the Company's business, operating results, financial condition and the actual outcome of matters as to which forward-looking statements are made in this report. If we do not successfully execute our strategic operating plan, or if our strategic operating plan is unsuccessful, our business, operating results and financial condition could be materially and adversely affected. We have announced several strategic plans in recent years, including several revenue-generating initiatives and plans to optimize our revenue, such as our plans to add capacity, including international expansion and new or increased service to mid-size airports, and initiatives and plans to optimize and control our costs. We also continue to explore opportunities to enhance our segmentation, including the introduction of Polaris, Basic Economy and United Premium Plus, and are implementing many programs and policies to improve the customer experience at all points in air travel. In developing our strategic operating plan, we make certain assumptions, including, but not limited to, those related to customer demand, competition, market consolidation, the availability of aircraft and the global economy. Actual economic, market and other conditions may be different from our assumptions. In 2019, our capacity growth was lower than planned due to the grounding of Boeing 737 MAX aircraft, among other factors, which adversely impacted our ability to execute our strategic operating plans. If we do not successfully execute our strategic operating plan, or if actual results vary significantly from our assumptions, our business, operating results and financial condition could be materially and adversely impacted. Unfavorable economic and political conditions, in the United States and globally, may have a material adverse effect on our business, operating results and financial condition. The Company's business and operating results are significantly impacted by U.S. and global economic and political conditions. The airline industry is highly cyclical, and the level of demand for air travel is correlated to the strength of the U.S. and global economies. Robust demand for the Company's air transportation services depends largely on favorable economic conditions, including the strength of the domestic and foreign economies, low unemployment levels, strong consumer confidence levels and the availability of consumer and business credit. Air transportation is often a discretionary purchase that leisure travelers may limit or eliminate during difficult economic times. Short-haul travelers, in particular, have the option to replace air travel with surface travel. In addition, during periods of unfavorable economic conditions, business travelers historically have reduced the volume of their travel, either due to cost-saving initiatives, the replacement of travel with alternatives such as videoconferencing, or as a result of decreased business activity requiring travel. During such periods, the Company's business and operating results may be adversely affected due to significant declines in industry passenger demand, particularly with respect to the Company's business and premium cabin travelers, and a reduction in fare levels. As a global business with operations outside of the United States from which it derives significant operating revenues, volatile conditions in certain international regions may have a negative impact on the Company's operating results and its ability to achieve its business objectives. The Company's international operations are a vital part of its worldwide airline network. Political disruptions and instability in certain regions can negatively impact the demand and network availability for air travel. Additionally, any deterioration in global trade relations, such as increased tariffs or other trade barriers, could result in a decrease in the demand for international air travel. Stagnant or weakening global economic conditions either in the United States or in other geographic regions may have a material adverse effect on the Company's revenues, operating results and liquidity. The global airline industry is highly competitive and susceptible to price discounting and changes in capacity, which could have a material adverse effect on our business, operating results and financial condition. The airline industry is highly competitive, marked by significant competition with respect to routes, fares, schedules (both timing and frequency), services, products, customer service and frequent flyer programs. Consolidation in the airline industry, the rise of well-funded government sponsored international carriers, changes in international alliances and the creation of immunized JBAs have altered and are expected to continue to alter the competitive landscape in the industry, resulting in the formation of airlines and alliances with increased financial resources, more extensive global networks and services and competitive cost structures. Airlines also compete by increasing or decreasing their capacity, including route systems and the number of destinations served. Several of the Company's domestic and international competitors have increased their international capacity by including service to some destinations that the Company currently serves, causing overlap in destinations served, and therefore, increasing competition for those destinations. This increased competition in both domestic and international markets may have a material adverse effect on the Company's business, operating results and financial condition. The Company's U.S. operations are subject to competition from traditional network carriers, national point-to-point carriers, and discount carriers, including low-cost carriers and ultra-low-cost carriers. Such carriers may have lower costs and provide service at lower fares to destinations also served by the Company. The significant presence of low-cost carriers and ultra-low-cost carriers, which engage in substantial price discounting, may diminish our ability to achieve sustained profitability on domestic and international routes. Our ability to compete in the domestic market effectively depends, in part, on our ability to maintain a competitive cost structure. If we cannot maintain our costs at a competitive level, then our business, operating results and financial condition could be materially and adversely affected. Our international operations are subject to competition from both foreign and domestic carriers. Competition is significant from government subsidized competitors from certain Middle East countries. These carriers have large numbers of international widebody aircraft on order and are increasing service to the U.S. from their hubs in the Middle East. The government support provided to these carriers has allowed them to grow quickly, reinvest in their product, invest in other airlines and expand their global presence. We also face competition from foreign carriers operating under "fifth freedom" rights permitted under international treaties that allow certain carriers to provide service to and from stopover points between their home country and ultimate destination, including points in the United States, in competition with service provided by us. Through alliance and other marketing and codesharing agreements with foreign carriers, U.S. carriers have increased their ability to sell international transportation, such as services to and beyond traditional global gateway cities. Similarly, foreign carriers have obtained increased access to interior U.S. passenger traffic beyond traditional U.S. gateway cities through these relationships. In addition, several JBAs among U.S. and foreign carriers have received grants of antitrust immunity allowing the participating carriers to coordinate schedules, pricing, sales and inventory. If we are not able to continue participating in these types of alliance and other marketing and codesharing agreements in the future, our business, operating results and financial condition could be materially and adversely affected. High and/or volatile fuel prices or significant disruptions in the supply of aircraft fuel could have a material adverse impact on the Company's strategic plans, operating results, financial condition and liquidity. Aircraft fuel is critical to the Company's operations and is one of our largest operating expenses. During the year ended December 31, 2019, the Company's fuel expense was approximately $9.0 billion. The timely and adequate supply of fuel to meet operational demand depends on the continued availability of reliable fuel supply sources, as well as related service and delivery infrastructure. Although the Company has some ability to cover short-term fuel supply and infrastructure disruptions at some major demand locations, it depends significantly on the continued performance of its vendors and service providers to maintain supply integrity. Consequently, the Company can neither predict nor guarantee the continued timely availability of aircraft fuel throughout the Company's system. Aircraft fuel has historically been the Company's most volatile operating expense due to the highly unpredictable nature of market prices for fuel. The Company generally sources fuel at prevailing market prices. Market prices for aircraft fuel have historically fluctuated substantially in short periods of time and continue to be highly volatile due to a dependence on a multitude of unpredictable factors beyond the Company's control. These factors include changes in global crude oil prices, the balance between aircraft fuel supply and demand, natural disasters, prevailing inventory levels and fuel production and transportation infrastructure. Prices of fuel are also impacted by indirect factors, such as geopolitical events, economic growth indicators, fiscal/monetary policies, fuel tax policies, changes in regulations, environmental concerns and financial investments in energy markets. Both actual changes in these factors, as well as changes in related market expectations, can potentially drive rapid changes in fuel prices in short periods of time. Given the highly competitive nature of the airline industry, the Company may not be able to increase its fares and fees sufficiently to offset the full impact of increases in fuel prices, especially if these increases are significant, rapid and sustained. Further, any such fare or fee increase may not be sustainable, may reduce the general demand for air travel and may also eventually impact the Company's strategic growth and investment plans for the future. In addition, decreases in fuel prices for an extended period of time may result in increased industry capacity, increased competitive actions for market share and lower fares or surcharges. If fuel prices were to then subsequently rise quickly, there may be a lag between the rise in fuel prices and any improvement of the revenue environment. To protect against increases in the market prices of fuel, the Company may hedge a portion of its future fuel requirements. The Company does not currently hedge its future fuel requirements. However, to the extent the Company decides to start a hedging program, such hedging program may not be successful in mitigating higher fuel costs, and any price protection provided may be limited due to the choice of hedging instruments and market conditions, including breakdown of correlation between hedging instrument and market price of aircraft fuel and failure of hedge counterparties. To the extent that the Company decides to hedge a portion of its future fuel requirements and uses hedge contracts that have the potential to create an obligation to pay upon settlement if fuel prices decline significantly, such hedge contracts may limit the Company's ability to benefit fully from lower fuel prices in the future. If fuel prices decline significantly from the levels existing at the time the Company enters into a hedge contract, the Company may be required to post collateral (margin) beyond certain thresholds. There can be no assurance that the Company's hedging arrangements, if any, will provide any particular level of protection against rises in fuel prices or that its counterparties will be able to perform under the Company's hedging arrangements. Additionally, deterioration in the Company's financial condition could negatively affect its ability to enter into new hedge contracts in the future. The Company relies heavily on technology and automated systems to operate its business and any significant failure or disruption of the technology or these systems could materially harm its business. The Company depends on automated systems and technology to operate its business, including, but not limited to, computerized airline reservation systems, demand prediction software, flight operations systems, revenue management systems, accounting systems, technical and business operations systems, telecommunication systems and commercial websites and applications, including www.united.com and the United Airlines app. United's website and other automated systems must be able to accommodate a high volume of traffic, maintain secure information and deliver important flight and schedule information, as well as process critical financial transactions. These systems could suffer substantial or repeated disruptions due to various events, some of which are beyond the Company's control, including natural disasters, power failures, terrorist attacks, equipment or software failures or cyber security attacks. We have initiatives in place to prevent disruptions and disaster recovery plans, and we continue to invest in improvements to these initiatives and plans; however, these measures may not be adequate to prevent or mitigate disruptions. Substantial or repeated systems failures or disruptions, including failures or disruptions related to the Company's complex integration of systems, could reduce the attractiveness of the Company's services versus those of its competitors, materially impair its ability to market its services and operate its flights, result in the unauthorized release of confidential or otherwise protected information, result in increased costs, lost revenue and the loss or compromise of important data, and may adversely affect the Company's business, operating results and financial condition. The Company's business relies extensively on third-party service providers, including certain technology providers. Failure of these parties to perform as expected, or interruptions in the Company's relationships with these providers or their provision of services to the Company, could have a material adverse effect on the Company's business, operating results and financial condition. The Company has engaged third-party service providers to perform a large number of functions that are integral to its business, including regional operations, operation of customer service call centers, distribution and sale of airline seat inventory, provision of information technology infrastructure and services, transmitting or uploading of data, provision of aircraft maintenance and repairs, provision of various utilities, performance of aircraft fueling operations and catering services, among other vital functions and services. The Company does not directly control these third-party service providers, although generally it does enter into agreements that define expected service performance and compliance requirements, such as compliance with legal requirements, including anti-corruption laws; however, there can be no assurance that our third-party service providers will adhere to these requirements. Any of these third-party service providers, however, may materially fail to meet its service performance commitments to the Company or may suffer disruptions to its systems that could impact its services. For example, failures in certain third-party technology or communications systems may cause flight delays or cancellations. The failure of any of the Company's third-party service providers to perform its service obligations adequately, or other interruptions of services, may reduce the Company's revenues and increase its expenses, prevent the Company from operating its flights and providing other services to its customers or result in adverse publicity or harm to our brand. We may also be subject to consequences from any illegal conduct of our third-party service providers, including for their failure to comply with anti-corruption laws, such as the U.S. Foreign Corrupt Practices Act. In addition, the Company's business and financial performance could be materially harmed if its customers believe that its services are unreliable or unsatisfactory. The Company may also have disagreements with such providers or such contracts may be terminated or may not be extended or renewed. For example, the number of flight reservations booked through third-party GDSs or online travel agents ("OTAs") may be adversely affected by disruptions in the business relationships between the Company and these suppliers. Such disruptions, including a failure to agree upon acceptable contract terms when contracts expire or otherwise become subject to renegotiation, may cause the Company's flight information to be limited or unavailable for display by the affected GDS or OTA operator, significantly increase fees for both the Company and GDS/OTA users and impair the Company's relationships with its customers and travel agencies. Any such disruptions or contract terminations may adversely impact our operations and financial results. If we are not able to negotiate or renew agreements with third-party service providers, or if we renew existing agreements on less favorable terms, our operations and financial results may be adversely affected. The Company could experience adverse publicity, harm to its brand, reduced travel demand and potential tort liability as a result of an accident, catastrophe or incident involving its aircraft or its operations, the aircraft or operations of its regional carriers, the aircraft or operations of its codeshare partners, or the aircraft or operations of another airline, which may result in a material adverse effect on the Company's business, operating results and financial condition. An accident, catastrophe or incident involving an aircraft that the Company operates, or an aircraft that is operated by a codeshare partner, one of the Company's regional carriers or another airline, or an incident involving the Company's operations, or the operations of a codeshare partner, one of the Company's regional carriers or of another airline, could have a material adverse effect on the Company if such accident, catastrophe or incident created a public perception that the Company's operations, or the operations of its codeshare partners or regional carriers, are not safe or reliable, or are less safe or reliable than other airlines. Additionally, any accident, catastrophe or incident involving an aircraft type that is operated by the Company, its codeshare partners or regional carriers could have a material adverse effect on the Company if such accident, catastrophe or incident creates a public perception that such aircraft type was not safe or reliable. Such public perception could, in turn, result in adverse publicity for the Company, cause harm to the Company's brand and reduce travel demand on the Company's flights, or the flights of its codeshare partners or regional carriers. In addition, any such accident, catastrophe or incident involving the Company, its regional carriers or its codeshare partners could expose the Company to significant tort liability. Although the Company currently maintains liability insurance in amounts and of the type the Company believes to be consistent with industry practice to cover damages arising from any such accident, catastrophe or incident, and the Company's codeshare partners and regional carriers carry similar insurance and generally indemnify the Company for their operations, if the Company's liability exceeds the applicable policy limits or the ability of another carrier to indemnify it, the Company could incur substantial losses from an accident, catastrophe or incident which may result in a material adverse effect on the Company's operating results and financial condition. Terrorist attacks, international hostilities or other security events, or the fear of terrorist attacks or hostilities, even if not made directly on the airline industry, could negatively affect the Company and the airline industry. Terrorist attacks or international hostilities, even if not made on or targeted directly at the airline industry, or the fear of or the precautions taken in anticipation of such attacks (including elevated national threat warnings, travel restrictions, selective cancellation or redirection of flights and new security regulations) could materially and adversely affect the Company and the airline industry. Security events pose a significant risk to our passenger and cargo operations. These events could include acts of violence in public areas that we cannot control. The Company's financial resources may not be sufficient to absorb the adverse effects of any future terrorist attacks, international hostilities or other security events. Any such events could have a material adverse impact on the Company's financial condition, liquidity and operating results. Increasing privacy and data security obligations or a significant data breach may adversely affect the Company's business. In our regular business operations, we collect, transmit, process and store sensitive data, including personal information of our customers and employees such as payment processing information and information of our business partners. The Company depends on the ability to use information we collect to provide our services and operate our business. The Company must manage increasing legislative, regulatory and consumer focus on privacy issues and data security. For example, in May 2018, the EU's General Data Protection Regulation became effective, which imposes significant privacy and data security requirements, as well as potential for substantial penalties for non-compliance. Recent penalties imposed by regulators have resulted in substantial adverse financial consequences to those companies. Also, some of the Company's commercial partners, such as credit card companies, have imposed data security standards that the Company must meet. These standards continue to evolve. The Company will continue its efforts to meet its privacy and data security obligations; however, it is possible that certain new obligations or customer expectations may be difficult to meet and could increase the Company's costs. Additionally, the Company must manage evolving cybersecurity risks. Our network systems and storage applications, and those systems and storage and other business applications maintained by our third-party providers, may be subject to attempts to gain unauthorized access, breach, malfeasance or other system disruptions. In some cases, it is difficult to anticipate or to detect immediately such incidents and the damage caused thereby. In addition, as attacks by cybercriminals become more sophisticated, frequent and intense, the costs of proactive defense measures may increase. While we continually work to safeguard our internal network systems, including through risk assessments, system monitoring, information security policies and employee awareness and training, and review and validate our third-party security standards, there is no assurance that such actions will be sufficient to prevent cyber-attacks or data breaches. The loss, disclosure, misappropriation of or access to customers', employees' or business partners' information or the Company's failure to meet its obligations could result in legal claims or proceedings, penalties and remediation costs. A significant data breach or the Company's failure to meet its obligations may adversely affect the Company's reputation, relationships with our business partners, business, operating results and financial condition. The mandatory grounding of our Boeing 737 MAX 9 aircraft may have a material adverse effect on our business, operating results and financial condition. On March 13, 2019, the Federal Aviation Administration issued an emergency order prohibiting the operation of Boeing 737 MAX series aircraft by U.S. certificated operators (the "FAA Order"). As a result, the Company grounded all 14 Boeing 737 MAX 9 aircraft in its fleet and Boeing also suspended deliveries of new Boeing 737 MAX series aircraft. The Company does not know whether, on what conditions or when the MAX grounding will end. The long-term operational and financial impact of this grounding is uncertain and could negatively affect the Company based on a number of factors, including, among others, the period of time the aircraft are unavailable, the availability of replacement aircraft, to the extent needed, and the circumstances of any reintroduction of the grounded aircraft to service. In 2019, the grounding affected the delivery of 16 Boeing 737 MAX aircraft that were scheduled for delivery and were not delivered, and it is also expected to affect the timing of future Boeing 737 MAX aircraft deliveries, including the 28 Boeing 737 MAX aircraft that the Company planned to take delivery in 2020. The extent of the delay of future deliveries is expected to be impacted by the length of time the FAA Order remains in place, Boeing's production rate and the pace at which Boeing can deliver aircraft following the lifting of the FAA Order, among other factors. The Company continues to make adjustments to its flight schedule and operations, including substituting replacement aircraft on routes originally intended to be flown by Boeing 737 MAX aircraft. The grounding has impacted the Company's ability to implement its strategic growth strategy, reducing the Company's scheduled capacity from its planned capacity, and has resulted in increased costs as well as lower operating revenue. The Company has had discussions with Boeing regarding compensation from Boeing for the Company's financial damages related to the grounding of the airline's Boeing 737 MAX aircraft; however, the parties have not agreed to any settlement, and the amount, nature and timing of any settlement with Boeing remains uncertain. Disruptions to our regional network and United Express flights provided by third-party regional carriers could adversely affect our business, operating results and financial condition. The Company has contractual relationships with various regional carriers to provide regional aircraft service branded as United Express. These regional operations are an extension of the Company's mainline network and complement the Company's operations by carrying traffic that connects to mainline service and allows flights to smaller cities that cannot be provided economically with mainline aircraft. The Company's business and operations are dependent on its regional flight network, with regional capacity accounting for approximately 11% of the Company's total capacity for the year ended December 31, 2019. Although the Company has agreements with its regional carriers that include contractually agreed performance metrics, each regional carrier is a separately certificated commercial air carrier and the Company does not control the operations of these carriers. A number of factors may impact the Company's regional network, including weather-related effects and seasonality. In addition, the decrease in qualified pilots driven by changes to federal regulations has adversely impacted and could continue to affect the Company's regional flying. For example, the FAA's expansion of minimum pilot qualification standards, including a requirement that a pilot have at least 1,500 total flight hours, as well as the FAA's revised pilot flight and duty time requirements under Part 117 of the Federal Aviation Regulations, have contributed to a smaller supply of pilots available to regional carriers. The decrease in qualified pilots resulting from the regulations as well as factors including a decreased student pilot population and a shrinking U.S. military from which to hire qualified pilots, could adversely impact the Company's operations and financial condition, and could also require the Company to reduce regional carrier flying. If a significant disruption occurs to the Company's regional network or flights or if one or more of the regional carriers with which the Company has relationships is unable to perform their obligations over an extended period of time, there could be a material adverse effect on the Company's business, operating results and financial condition. Current or future litigation and regulatory actions, or failure to comply with the terms of any settlement, order or arrangement relating to these actions, could have a material adverse impact on the Company. From time to time, we are subject to litigation and other legal and regulatory proceedings relating to our business or investigations or other actions by governmental agencies, including as described in Part I, Item 3, Legal Proceedings, of this report. No assurances can be given that the results of these or new matters will be favorable to us. An adverse resolution of lawsuits, arbitrations, investigations or other proceedings or actions could have a material adverse effect on our financial condition and operating results, including as a result of non-monetary remedies, and could also result in adverse publicity. Defending ourselves in these matters may be time-consuming, expensive and disruptive to normal business operations and may result in significant expense and a diversion of management's time and attention from the operation of our business, which could impede our ability to achieve our business objectives. Additionally, any amount that we may be required to pay to satisfy a judgment, settlement, fine or penalty may not be covered by insurance. If we fail to comply with the terms contained in any settlement, order or agreement with a governmental authority relating to these matters, we could be subject to criminal or civil penalties, which could have a material adverse impact on the Company. Under our charter and certain indemnification agreements that we have entered into (and may in the future enter into) with our officers, directors and certain third parties, we could be required to indemnify and advance expenses to them in connection with their involvement in certain actions, suits, investigations and other proceedings. There can be no assurance that any of these payments will not be material. Our significant investments in other airlines, including in other parts of the world, and the commercial relationships that we have with those carriers may not produce the returns or results we expect. An important part of our strategy to expand our global network includes making significant investments in airlines both domestically and in other parts of the world and expanding our commercial relationships with these carriers. For example, in January 2019, we completed the acquisition of a 49.9% interest in ManaAir LLC, which, as of immediately following the closing of that investment, owns 100% of the equity interests in ExpressJet Airlines LLC, a domestic regional airline. We also have minority equity interests in CommutAir and Republic Airways Holdings Inc. See Note 9 to the financial statements included in Part II, Item 8 of this report for additional information regarding our investments in regional airlines. We also have significant investments in Latin American airlines, including significant investments in Avianca Holdings, S.A. ("AVH") and BRW Aviation LLC ("BRW"), an affiliate of Synergy Aerospace Corporation and the majority shareholder of AVH, and an equity investment in Azul. See Note 8 and Note 9 to the financial statements included in Part II, Item 8 of this report for additional information regarding our investments in AVH and Azul, respectively. See also the additional risks with respect to our investment in AVH described in this Part I, Item 1A. Risk Factors. We expect to continue exploring similar non-controlling investments in, and entering into JBAs, commercial agreements, loan transactions and strategic alliances with, other carriers as part of our regional and global business strategy. These transactions and relationships involve significant challenges and risks, and we face competition in forming and maintaining these relationships, since there are a limited number of potential arrangements and other airlines are looking to enter into similar relationships. We are dependent on these other carriers for significant aspects of our network in the regions in which they operate. While we work closely with these carriers, each is a separately certificated commercial air carrier, and we do not have control over their operations, strategy, management or business methods. And not only are these airlines subject to a number of the same risks as our business, which are described elsewhere in this Part I, Item 1A. Risk Factors, including competitive pressures on pricing, demand and capacity, changes in aircraft fuel pricing, and the impact of global and local political and economic conditions on operations and customer travel patterns, among others, they are also subject to their own distinct financial and operational risks. As a result of these and other factors, we may not realize a satisfactory return on our investment, and we may not receive repayment of any invested or loaned funds. Further, these investments may not generate the revenue or operational synergies we expect, and they may distract management focus from our operations or other strategic options. Finally, our reliance on these other carriers in the regions in which they operate may negatively impact our regional and global operations and results if those carriers are impacted by general business risks or perform below our expectations or needs. Any one or more of these events could have a material adverse effect on our operating results or financial condition. We may also be subject to consequences from any illegal conduct of JBA partners, including for failure to comply with anti-corruption laws such as the U.S. Foreign Corrupt Practices Act. Furthermore, our relationships with these carriers may be subject to the laws and regulations of non-U.S. jurisdictions in which these carriers are located or conduct business. In addition, any political or regulatory change in these jurisdictions that negatively impacts or prohibits our arrangements with these carriers could have an adverse effect on our operating results or financial condition. To the extent that the operations of any of these carriers are disrupted over an extended period of time or their actions subject us to the consequences of failure to comply with laws and regulations, our operating results may be adversely affected. Our significant investments in AVH and its affiliates, and the commercial relationships that we have with Avianca may not produce the returns or results we expect. In November 2018, as part of our global network strategy, United entered into a revenue-sharing JBA with Avianca, a subsidiary of AVH, Copa and several of their respective affiliates, subject to regulatory approval. Concurrently with this transaction, United, as lender, entered into a Term Loan Agreement (the "BRW Term Loan Agreement") with, among others, BRW Aviation Holding LLC ("BRW Holding") and BRW, as guarantor and borrower, respectively. Pursuant to the BRW Term Loan Agreement, United provided to BRW a $456 million term loan (the "BRW Term Loan"), secured by a pledge of BRW's equity, as well as BRW's 516 million common shares of AVH (which are eligible to be converted into the same number of preferred shares, which maybe be deposited with the depositary for AVH's American Depositary Receipts ("ADRs"), the class of AVH securities that trades on the New York Stock Exchange (the "NYSE"), in exchange for 64.5 million ADRs) (such shares and equity, collectively, the "BRW Loan Collateral"). BRW is currently in default under the BRW Term Loan Agreement. In order to protect the value of its collateral, on May 24, 2019, United began to exercise certain remedies available to it under the terms of the BRW Term Loan Agreement and related documents. In connection with the delivery by United of a notice of default to BRW, Kingsland Holdings Limited ("Kingsland"), AVH's largest minority shareholder, was granted, in accordance with the agreements related to the BRW Term Loan Agreement, authority to manage BRW, which remains the majority shareholder of AVH. After a hearing on September 26, 2019, a New York state court granted Kingsland summary judgment authorizing it to foreclose on the BRW Loan Collateral under the BRW Term Loan Agreement. Kingsland is continuing with the foreclosure process, which is expected to result in a judicially supervised sale of the BRW Loan Collateral. The New York state court also granted Kingsland's motion for a preliminary injunction that, among other things, enjoins BRW Holding from interfering with Kingsland's ability to exercise voting and other rights in certain equity interests in BRW. These rulings are intermediate steps in the judicial foreclosure process in New York and are subject to appeal. The repayment of the BRW Term Loan is dependent on this judicial foreclosure process and there is no assurance that a judicial foreclosure sale will be completed, or, if completed, will result in the full satisfaction of all of the obligations under the BRW Term Loan. Our ability to enforce a deficiency judgment against BRW in the event that the proceeds from the sale of the BRW Loan Collateral in the judicial foreclosure are insufficient to repay the full amount of the BRW Term Loan may be limited. Any of these circumstances may lead to a loss or delay in the repayment of the BRW Term Loan. Further, the amount we receive from the foreclosure sale of the BRW Loan Collateral may be inadequate to fully pay the amounts owed to us by BRW and our costs incurred to foreclose, repossess and sell the property. In November 2019, United entered into a senior secured convertible term loan agreement (the "AVH Convertible Loan Agreement") with, among others, AVH, as borrower, for the provision by the lenders thereunder (including United) to AVH of convertible term loans for general corporate purposes. In December 2019, United provided such a convertible term loan to AVH under the Convertible Loan Agreement in the aggregate amount of $150 million (the "AVH Convertible Loan"). See Note 8 to the financial statements included in Part II, Item 8 of this report for additional information regarding our investments in AVH and its affiliates. These transactions and relationships involve significant challenges and risks, particularly given AVH's recent debt restructuring and the judicial foreclosure process to which the repayment of the BRW Term Loan is subject. While AVH has successfully carried out its debt restructuring plan to date, there is no guarantee that such debt restructuring plan will improve AVH's long-term financial condition, United's exposure to which has increased with the completion of the AVH Convertible Loan. While we work closely with Avianca in connection with the JBA, and have supported AVH by providing capital in the form of the AVH Convertible Loan, Avianca is a separately certificated commercial air carrier, and we do not have control over its or AVH's operations, strategy, management or business methods. Avianca is also subject to a number of the same risks as our business, which are described in this Part I, Item 1A, Risk Factors, including competitive pressures on pricing, demand and capacity, changes in aircraft fuel pricing, and the impact of global and local political and economic conditions on operations and customer travel patterns, among others, as well as to its own distinct financial and operational risks. In addition, the value of the BRW Loan Collateral and the collateral securing the AVH Convertible Loan is subject to market and other conditions. Changes in the aviation market may adversely affect the value of the BRW Loan Collateral and the collateral securing the AVH Convertible Loan and thereby lower the value to be derived from a foreclosure or other exercise of remedies with respect to the BRW Term Loan Agreement or the AVH Convertible Loan. As a result of these and other factors, including delays in foreclosure proceedings, we may not receive full repayment of our BRW Term Loan or our AVH Convertible Loan, and we may be unable to realize the full value of the BRW Loan Collateral or the collateral securing the AVH Convertible Loan. As a consequence, we may not realize a satisfactory return on our invested or loaned funds with respect to AVH and its affiliates. Further, these investments may not generate the revenue or operational synergies we expect, and they may distract management focus from our operations or other strategic options. Finally, our reliance on Avianca in the region in which it operates may negatively impact our global operations and results if AVH does not successfully recover from its debt restructuring or is otherwise impacted by general business risks or performs below our expectations or needs. Any one or more of these events could have a material adverse effect on our operating results or financial condition. The airline industry may undergo further change with respect to alliances and JBAs or due to consolidations, any of which could have a material adverse effect on the Company. The Company faces, and may continue to face, strong competition from other carriers due to the modification of alliances and formation of new JBAs. Carriers may improve their competitive positions through airline alliances, slot swaps and/or JBAs. Certain types of airline JBAs further competition by allowing multiple airlines to coordinate routes, pool revenues and costs, and enjoy other mutual benefits, achieving many of the benefits of consolidation. Open Skies agreements, including the longstanding agreements between the United States and each of the EU, Canada, Japan, Korea, New Zealand, Australia, Colombia and Panama, as well as the more recent agreements between the United States and each of Mexico and Brazil, may also give rise to better integration opportunities among international carriers. Movement of airlines between current global airline alliances could reduce joint network coverage for members of such alliances while also creating opportunities for JBAs and bilateral alliances that did not exist before such realignment. Further airline and airline alliance consolidations or reorganizations could occur in the future. The Company routinely engages in analyses and discussions regarding its own strategic position, including current and potential alliances, asset acquisitions and divestitures and may have future discussions with other airlines regarding strategic activities. If other airlines participate in such activities, those airlines may significantly improve their cost structures or revenue generation capabilities, thereby potentially making them stronger competitors of the Company and potentially impairing the Company's ability to realize expected benefits from its own strategic relationships. Orders for new aircraft typically must be placed years in advance of scheduled deliveries, and changes in the Company's network strategy over time or other factors outside of the Company's control may make aircraft on order less economic for the Company, result in costs related to modification or termination of aircraft orders or cause the Company to enter into orders for new aircraft on less favorable terms. The Company's orders for new aircraft are typically made years in advance of actual delivery of such aircraft, and the financial commitment required for purchases of new aircraft is substantial. At December 31, 2019, the Company had firm commitments to purchase 304 new aircraft from The Boeing Company ("Boeing"), Airbus S.A.S ("Airbus") and Embraer S.A. ("Embraer"), as well as related agreements with engine manufacturers, maintenance providers and others. As of December 31, 2019, the Company's commitments relating to the acquisition of aircraft and related spare engines, aircraft improvements and other related obligations aggregated to a total of $26.7 billion. Subsequent to the Company placing an order for new aircraft, the Company's network strategy may change. As a result, the Company's preference for a particular aircraft that it has ordered, often years in advance, may be decreased or eliminated. If the Company were to modify or terminate any of its existing aircraft order commitments, it may be responsible for material liabilities to its counterparties arising from any such modification. Additionally, the Company may have a need for additional aircraft that are not available under its existing orders. In such cases, the Company may seek to acquire aircraft from other sources, such as through lease arrangements, which may result in higher costs or less favorable terms, or through the purchase or lease of used aircraft. The Company may not be able to acquire such aircraft when needed on favorable terms or at all. The imposition of new tariffs, or any increase in existing tariffs, on the importation of commercial aircraft that the Company orders may result in higher costs. For example, in October 2019, the United States imposed tariffs on certain imports from the EU, including a customs duty at an ad valorem rate of 10% on new commercial aircraft, which rate, in February 2020, was increased to 15%. These tariffs apply to certain new Airbus aircraft that we have on order. While the scope and rate of these tariffs are subject to change, if and to the extent these tariffs are imposed on us, they could increase the effective cost of, among other things, new Airbus aircraft. A majority of the Company's aircraft and certain parts are sourced from single suppliers; therefore, the Company would be materially and adversely affected if it were unable to obtain timely deliveries, additional equipment or support from any of these suppliers. The Company currently sources the majority of its aircraft and many related aircraft parts from Boeing. In addition, our aircraft suppliers are dependent on other suppliers for certain other aircraft parts. Therefore, if the Company is unable to acquire additional aircraft from Boeing, or if Boeing fails to make timely deliveries of aircraft or to provide adequate support for its products, the Company's operations could be materially and adversely affected. The Company is also dependent on a limited number of suppliers for aircraft engines and certain other aircraft parts and could, therefore, also be materially and adversely affected in the event of the unavailability of these engines and other parts. Union disputes, employee strikes or slowdowns, and other labor-related disruptions could adversely affect the Company's operations and could result in increased costs that impair its financial performance. United is a highly unionized company. As of December 31, 2019, the Company and its subsidiaries had approximately 96,000 active employees, of whom approximately 84% were represented by various U.S. labor organizations. See Part I, Item 1. Business-Employees, of this report for additional information on our represented employee groups and collective bargaining agreements. There is a risk that unions or individual employees might pursue judicial or arbitral claims arising out of changes implemented as a result of the Company entering into collective bargaining agreements with its represented employee groups. There is also a possibility that employees or unions could engage in job actions such as slowdowns, work-to-rule campaigns, sick-outs or other actions designed to disrupt the Company's normal operations, in an attempt to pressure the Company in collective bargaining negotiations. Although the RLA makes such actions unlawful until the parties have been lawfully released to self-help, and the Company can seek injunctive relief against premature self-help, such actions can cause significant harm even if ultimately enjoined. Similarly, if the operations of our third-party regional carriers, ground handlers or other vendors are impacted by labor-related disruptions, our operations could be adversely affected. In addition, collective bargaining agreements with the Company's represented employee groups increase the Company's labor costs, which increase could be material. An outbreak of disease or similar public health threat, such as the coronavirus, could have a material adverse impact on the Company's business, operating results and financial condition. An outbreak of disease or similar public health threat, or fear of such an event, that affects travel demand, travel behavior, or travel restrictions could have a material adverse impact on the Company's business, financial condition and operating results. In addition, outbreaks of disease could result in increased government restrictions and regulation, including quarantines of our personnel or an inability to access facilities or our aircraft, which could adversely affect our operations. In December 2019, a novel strain of coronavirus ("COVID-19") was reported in Wuhan, China. The World Health Organization has declared COVID-19 to constitute a "Public Health Emergency of International Concern." On January 30, 2020, the U.S. Department of State issued a Level 4 "do not travel" advisory for China. The U.S. government has also implemented enhanced screenings, quarantine requirements and travel restrictions in connection with the COVID-19 outbreak. The Company has suspended its flights between the United States and each of Beijing, Chengdu, Shanghai and Hong Kong through April 24, 2020. These routes represented approximately 5% of the Company's 2020 planned capacity and the Company's other trans-Pacific routes represented an additional 10% of the Company's 2020 planned capacity. As of the date of this report, the Company is experiencing an approximately 100% decline in near-term demand to China and an approximately 75% decline in near-term demand on the rest of the Company's trans-Pacific routes. The extent of the impact of the COVID-19 on the Company's operational and financial performance will depend on future developments, including the duration and spread of the outbreak and related travel advisories and restrictions and the impact of the COVID-19 on overall demand for air travel, all of which are highly uncertain and cannot be predicted. If traffic on the Company's trans-Pacific routes were to remain at these levels for an extended period, and/or routes in other parts of the Company's network begin to see significant declines in demand, our results of operations for full year 2020 may be materially adversely affected. If we experience changes in, or are unable to retain, our senior management team or other key employees, our operating results could be adversely affected. Much of our future success depends on the continued availability of skilled personnel with industry experience and knowledge, including our senior management team and other key employees. If we are unable to attract and retain talented, highly qualified senior management and other key employees, or if we are unable to effectively provide for the succession of senior management, our business may be adversely affected. Extended interruptions or disruptions in service at major airports where we operate could have a material adverse impact on our operations. The airline industry is heavily dependent on business models that concentrate operations in major airports in the United States and throughout the world. An extended interruption or disruption at an airport where we have significant operations could have a material impact on our business, financial condition and results of operation. We operate principally through our domestic hubs in at Newark, Chicago O'Hare, Denver, Houston Bush, LAX, Guam, SFO and Washington Dulles. Substantially all of our flights either originate in or fly into one of these locations. A significant interruption or disruption in service at one of our hubs or other airports where we have a significant presence resulting from ATC delays, weather conditions, natural disasters, growth constraints, relations with third-party service providers, failure of computer systems, disruptions to government agencies or personnel (including as a result of government shutdowns), disruptions at airport facilities or other key facilities used by us to manage our operations, labor relations, power supplies, fuel supplies, terrorist activities, international hostilities or otherwise could result in the cancellation or delay of a significant portion of our flights and, as a result, could have a material impact on our business, operating results and financial condition. We have minimal control over the operation, quality or maintenance of these services or whether vendors will improve or continue to provide services that are essential to our business. The airline industry is subject to extensive government regulation, which imposes significant costs and may adversely impact our business, operating results and financial condition. Airlines are subject to extensive regulatory and legal oversight. Compliance with U.S. and international regulations imposes significant costs and may have adverse effects on the Company. Laws, regulations, taxes and airport rates and charges, both domestically and internationally, have been proposed from time to time that could significantly increase the cost of airline operations or reduce airline revenue. The airline industry is heavily taxed and additional taxation could negatively impact our business. United provides air transportation under certificates of public convenience and necessity issued by the DOT. If the DOT altered, amended, modified, suspended or revoked these certificates, it could have a material adverse effect on the Company's business. The DOT also regulates consumer protection and, through its investigations or rulemaking authority, could impose restrictions that materially impact the Company's business. The FAA regulates the safety of United's operations. United operates pursuant to an air carrier operating certificate issued by the FAA. The FAA's regulations include stringent pilot flight and duty time requirements under Part 117 of the Federal Aviation Regulations, as well as minimum qualifications for air carrier first officers. These regulations have caused mainline airlines to hire regional pilots, while simultaneously significantly reducing the pool of new pilots from which regional carriers themselves can hire. Although this is an industry issue, it directly affects the Company and has required it to reduce regional partner flying, as several regional partners have experienced difficulty flying their schedules due to reduced pilot availability. From time to time, the FAA also issues orders, airworthiness directives and other regulations relating to the maintenance and operation of aircraft that require material expenditures or operational restrictions by the Company. These FAA orders and directives have resulted in the temporary grounding of an entire aircraft type if the FAA identifies design, manufacturing, maintenance or other issues requiring immediate corrective action (including the FAA Order grounding Boeing 737 MAX aircraft). These FAA directives or requirements could have a material adverse effect on the Company. In 2018, the U.S. Congress approved a five-year reauthorization for the FAA, which encompasses significant aviation tax and policy-related issues. The law includes a range of policy changes related to airline customer service and aviation safety which are ongoing and, depending on how they are implemented, could impact our operations and costs. Additionally, the U.S. Congress may consider legislation related to aviation safety as well as environmental issues which could impact the Company and the airline industry. The Company's operations may also be adversely impacted due to the existing antiquated ATC system utilized by the U.S. government and regulated by the FAA. During peak travel periods in certain markets, the current ATC system's inability to handle demand has led to short-term capacity constraints imposed by government agencies and resulted in delays and disruptions of air traffic. In addition, the current system will not be able to effectively handle projected future air traffic growth. The outdated technologies also cause the ATC to be less resilient in the event of a failure, causing flight cancellations and delays. Imposition of these ATC constraints on a long-term basis may have a material adverse effect on the Company's operations. Failure to update the ATC system in a timely manner and the substantial funding requirements of a modernized ATC system that may be imposed on air carriers may have an adverse impact on the Company's financial condition or operating results. Access to landing and take-off rights, or "slots," at several major U.S. airports and many foreign airports served by the Company are, or recently have been, subject to government regulation. Certain of the Company's major hubs are among the most congested airports in the United States and have been or could be the subject of regulatory action that might limit the number of flights and/or increase costs of operations at certain times or throughout the day. The FAA may limit the Company's airport access by limiting the number of departure and arrival slots at high density traffic airports, which could affect the Company's ownership and transfer rights, and local airport authorities may have the ability to control access to certain facilities or the cost of access to their facilities, which could have an adverse effect on the Company's business. The FAA historically has taken actions with respect to airlines' slot holdings that airlines have challenged; if the FAA were to take actions that adversely affect the Company's slot holdings, the Company could incur substantial costs to preserve its slots or may lose slots. If slots are eliminated at an airport, or if the number of hours of operation governed by slots is reduced at an airport, the lack of controls on take-offs and landings could result in greater congestion both at the affected airport or in the regional airspace (e.g., the New York City metropolitan region airspace) and could significantly impact the Company's operations. Further, the Company's operating costs at airports, including the Company's major hubs, may increase significantly because of capital improvements at such airports that the Company may be required to fund, directly or indirectly. Such costs could be imposed by the relevant airport authority without the Company's approval and may have a material adverse effect on the Company's financial condition. The ability of carriers to operate flights on international routes between the United States and other countries is highly regulated. Applicable arrangements between the United States and foreign governments may be amended from time to time, government policies with respect to airport operations may be revised, and the availability of appropriate slots or facilities may change. The Company currently operates a number of flights on international routes under government arrangements, regulations or policies that designate the number of carriers permitted to operate on such routes, the capacity of the carriers providing services on such routes, the airports at which carriers may operate international flights, or the number of carriers allowed access to particular airports. Any limitations, additions or modifications to such arrangements, regulations or policies could have a material adverse effect on the Company's financial condition and operating results. Additionally, a change in law, regulation or policy for any of the Company's international routes, such as Open Skies, could have a material adverse impact on the Company's financial condition and operating results and could result in the impairment of material amounts of related tangible and intangible assets. In addition, competition from revenue-sharing JBAs and other alliance arrangements by and among other airlines could impair the value of the Company's business and assets on the Open Skies routes. The Company's plans to enter into or expand U.S. antitrust immunized alliances and JBAs on various international routes are subject to receipt of approvals from applicable U.S. federal authorities and obtaining other applicable foreign government clearances or satisfying the necessary applicable regulatory requirements. There can be no assurance that such approvals and clearances will be granted or will continue in effect upon further regulatory review or that changes in regulatory requirements or standards can be satisfied. See Part I, Item 1. Business-Industry Regulation, of this report for additional information on government regulation impacting the Company. We are subject to many forms of environmental regulation and liability and risks associated with climate change, and may incur substantial costs as a result. Many aspects of the Company's operations are subject to increasingly stringent federal, state, local and international laws protecting the environment, including those relating to emissions to the air, water discharges, safe drinking water and the use and management of hazardous materials and wastes. Compliance with existing and future environmental laws and regulations can require significant expenditures and violations can lead to significant fines and penalties. In addition, from time to time we are identified as a responsible party for environmental investigation and remediation costs under applicable environmental laws due to the disposal of hazardous substances generated by our operations. We could also be subject to environmental liability claims from various parties, including airport authorities, related to our operations at our owned or leased premises or the off-site disposal of waste generated at our facilities. We may incur substantial costs as a result of changes in weather patterns due to climate change. Increases in the frequency, severity or duration of severe weather events such as thunderstorms, hurricanes, flooding, typhoons, tornados and other severe weather events could result in increases in delays and cancellations, turbulence-related injuries and fuel consumption to avoid such weather, any of which could result in significant loss of revenue and higher costs. To mitigate climate change risks, CORSIA has been developed by ICAO, a UN specialized agency. CORSIA is intended to create a single global market-based measure to achieve carbon-neutral growth for international aviation after 2020 through airline purchases of carbon offset credits. Certain CORSIA program details remain to be developed and could potentially be affected by political developments in participating countries or the results of the pilot phase of the program, and thus the impact of CORSIA cannot be fully predicted. However, CORSIA is expected to result in increased operating costs for airlines that operate internationally, including the Company. In addition to CORSIA, the EPA has begun preliminary work to adopt its own aircraft engine GHG emission standards, which were expected to be aligned with recent ICAO carbon dioxide emission standards. The timing of any U.S. EPA aircraft engine GHG emission standards is currently unknown, but some jurisdictions in which United operates have adopted or are considering GHG emission reduction initiatives, which could impact various aspects of the Company's business. The precise nature of future requirements and their applicability to the Company are difficult to predict, but the financial impact to the Company and the aviation industry would likely be adverse and could be significant. See Part I, Item 1. Business-Industry Regulation-Environmental Regulation, of this report for additional information on environmental regulation impacting the Company. The United Kingdom's withdrawal from the EU may adversely impact our operations in the United Kingdom and elsewhere. In June 2016, United Kingdom ("UK") voters approved an advisory referendum for the UK to exit the EU. The UK parliament voted in favor of allowing the government to commence negotiations to determine the future terms of the UK's relationship with the EU, including the terms of trade between the UK and the EU and other nations. On January 31, 2020, the UK withdrew from the EU, and started a transition period that will potentially run through December 31, 2020. The nature and terms of the UK's relationship with the EU after the transition period remain uncertain. In connection with a UK exit from the EU, we could face new challenges in our operations, such as instability in global financial and foreign exchange markets. This instability could result in market volatility, including in the value of the British pound and European euro, additional travel restrictions on passengers traveling between the UK and other EU countries, changes to the legal status of EU-resident employees, legal uncertainty and divergent national laws and regulations. At this time, we cannot predict the impact that the UK's exit from the EU will have on our business generally and our UK and European operations more specifically, and no assurance can be given that our operating results, financial condition and prospects would not be adversely impacted by the result. The Company's operating results fluctuate due to seasonality and other factors associated with the airline industry, many of which are beyond the Company's control. Due to greater demand for air travel during the spring and summer months, revenues in the airline industry in the second and third quarters of the year are generally stronger than revenues in the first and fourth quarters of the year, which are periods of lower travel demand. The Company's operating results generally reflect this seasonality, but have also been impacted by numerous other factors that are not necessarily seasonal, including, among others, extreme or severe weather, outbreaks of disease or pandemics, ATC congestion, geological events, political instability, terrorism, natural disasters, changes in the competitive environment due to industry consolidation, tax obligations, general economic conditions and other factors. As a result, the Company's quarterly operating results are not necessarily indicative of operating results for an entire year and historical operating results in a quarterly or annual period are not necessarily indicative of future operating results. Increases in insurance costs or inadequate insurance coverage may materially and adversely impact our business, operating results and financial condition. The Company could be exposed to significant liability or loss if its property or operations were to be affected by a natural catastrophe or other event, including aircraft accidents. The Company maintains insurance policies, including, but not limited to, terrorism, aviation hull and liability, workers' compensation and property and business interruption insurance, but we are not fully insured against all potential hazards and risks incident to our business. If the Company is unable to obtain sufficient insurance with acceptable terms, the costs of such insurance increase materially, or if the coverage obtained is insufficient relative to actual liability or losses that the Company experiences, whether due to insurance market conditions, policy limitations and exclusions or otherwise, our operating results and financial condition could be materially and adversely affected. The Company has a significant amount of financial leverage from fixed obligations, and insufficient liquidity may have a material adverse effect on the Company's financial condition and business. The Company has a significant amount of financial leverage from fixed obligations, including aircraft lease and debt financings, leases of airport property and other facilities, and other material cash obligations. In addition, the Company has substantial noncancelable commitments for capital expenditures, including for the acquisition of new aircraft and related spare engines. Although the Company's cash flows from operations and its available capital, including the proceeds from financing transactions, have been sufficient to meet these obligations and commitments to date, the Company's future liquidity could be negatively affected by the risk factors discussed in this report. If the Company's liquidity is materially diminished, the Company might not be able to timely pay its leases and debts or comply with certain operating and financial covenants under its financing and credit card processing agreements or with other material provisions of its contractual obligations. The Company's substantial level of indebtedness and non-investment grade credit rating, as well as market conditions and the availability of assets as collateral for loans or other indebtedness, may make it difficult for the Company to raise additional capital if needed to meet its liquidity needs on acceptable terms, or at all. In addition, as of December 31, 2019, the Company had $3.4 billion in variable rate indebtedness, all or a portion of which uses London interbank offered rates ("LIBOR") as a benchmark for establishing applicable rates. As announced in July 2017, LIBOR is expected to be phased out by the end of 2021. Although many of our LIBOR-based obligations provide for alternative methods of calculating the interest rate payable if LIBOR is not reported, the extent and manner of any future changes with respect to methods of calculating LIBOR or replacing LIBOR with another benchmark are unknown and impossible to predict at this time and, as such, may result in interest rates that are materially higher than current interest rates. If interest rates applicable to the Company's variable interest indebtedness increase, the Company's interest expense will also increase, which could make it difficult for the Company to make interest payments and fund other fixed costs and, in turn, adversely impact our cash flow available for general corporate purposes. See Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations, of this report for additional information regarding the Company's liquidity. Agreements governing our debt include financial and other covenants. Failure to comply with these covenants could result in events of default. Our financing agreements include various financial and other covenants. Certain of these covenants require UAL or United, as applicable, to maintain minimum liquidity and/or minimum collateral coverage ratios. UAL's or United's ability to comply with these covenants may be affected by events beyond its control, including the overall industry revenue environment, the level of fuel costs and the appraised value of the collateral. In addition, our financing agreements contain other negative covenants customary for such financings. These covenants are subject to important exceptions and qualifications. If we fail to comply with these covenants and are unable to remedy or obtain a waiver or amendment, an event of default would result. If an event of default were to occur, the lenders could, among other things, declare outstanding amounts immediately due and payable. In addition, an event of default or declaration of acceleration under one financing agreement could also result in an event of default under other of our financing agreements due to cross-default and cross-acceleration provisions. The acceleration of significant amounts of debt could require us to renegotiate, repay or refinance the obligations under our financing arrangements. The Company may never realize the full value of its intangible assets or its long-lived assets causing it to record impairments that may negatively affect its financial condition and operating results. In accordance with applicable accounting standards, the Company is required to test its indefinite-lived intangible assets for impairment on an annual basis, or more frequently where there is an indication of impairment. In addition, the Company is required to test certain of its other assets for impairment where there is any indication that an asset may be impaired. The Company may be required to recognize losses in the future due to, among other factors, extreme fuel price volatility, tight credit markets, government regulatory changes, decline in the fair values of certain tangible or intangible assets, such as aircraft, route authorities, airport slots and frequent flyer database, unfavorable trends in historical or forecasted results of operations and cash flows and an uncertain economic environment, as well as other uncertainties. For example, in 2019 and 2018, the Company recorded impairment charges of $90 million and $206 million, respectively, associated with its Hong Kong routes, resulting in the full impairment of these assets. The Company can provide no assurance that a material impairment loss of tangible or intangible assets will not occur in a future period. The value of the Company's aircraft could be impacted in future periods by changes in supply and demand for these aircraft. Such changes in supply and demand for certain aircraft types could result from the grounding of aircraft. An impairment loss could have a material adverse effect on the Company's financial condition and operating results. Any damage to our reputation or brand image could adversely affect our business or financial results. We operate in a public-facing industry and maintaining a good reputation is critical to our business. The Company's reputation or brand image could be adversely impacted by any failure to maintain satisfactory practices for all of our operations and activities, any failure to achieve and/or make progress toward our environmental and sustainability goals, public pressure from investors or policy groups to change our policies, customer perceptions of our advertising campaigns, sponsorship arrangements or marketing programs, customer perceptions of our use of social media, or customer perceptions of statements made by us, our employees and executives, agents or other third parties. Damage to our reputation or brand image or loss of customer confidence in our services could adversely affect our business and financial results, as well as require additional resources to rebuild our reputation.

ITEM 1A. RISK FACTORS. The following risk factors should be read carefully when evaluating the Company's business and the forward-looking statements contained in this report and other statements the Company or its representatives make from time to time. Any of the following risks could materially and adversely affect the Company's business, operating results, financial condition and the actual outcome of matters as to which forward-looking statements are made in this report. If we do not successfully execute our strategic operating plan, or if our strategic operating plan is unsuccessful, our business, operating results and financial condition could be materially and adversely affected. We have announced several strategic plans in recent years, including several revenue-generating initiatives and plans to optimize our revenue, such as our plans to add capacity, including international expansion and new or increased service to mid-size airports, and initiatives and plans to optimize and control our costs. We also continue to explore opportunities to enhance our segmentation, including the introduction of Polaris, Basic Economy and United Premium Plus, and are implementing many programs and policies to improve the customer experience at all points in air travel. In developing our strategic operating plan, we make certain assumptions including, but not limited to, those related to customer demand, competition, market consolidation and the global economy. Actual economic, market and other conditions may be different from our assumptions and we may not be able to successfully execute our strategic operating plan. If we do not successfully execute our strategic operating plan, or if actual results vary significantly from our assumptions, our business, operating results and financial condition could be materially and adversely impacted. Unfavorable economic and political conditions, in the United States and globally, may have a material adverse effect on our business, operating results and financial condition. The Company's business and operating results are significantly impacted by U.S. and global economic and political conditions. The airline industry is highly cyclical, and the level of demand for air travel is correlated to the strength of the U.S. and global economies. Robust demand for the Company's air transportation services depends largely on favorable economic conditions, including the strength of the domestic and foreign economies, low unemployment levels, strong consumer confidence levels and the availability of consumer and business credit. Air transportation is often a discretionary purchase that leisure travelers may limit or eliminate during difficult economic times. Short-haul travelers, in particular, have the option to replace air travel with surface travel. In addition, during periods of unfavorable economic conditions, business travelers historically have reduced the volume of their travel, either due to cost-saving initiatives, the replacement of travel with alternatives such as videoconferencing, or as a result of decreased business activity requiring travel. During such periods, the Company's business and operating results may be adversely affected due to significant declines in industry passenger demand, particularly with respect to the Company's business and premium cabin travelers, and a reduction in fare levels. As a global business with operations outside of the United States from which it derives significant operating revenues, volatile conditions in certain international regions may have a negative impact on the Company's operating results and its ability to achieve its business objectives. The Company's international operations are a vital part of its worldwide airline network. Political disruptions and instability in certain regions can negatively impact the demand and network availability for air travel. Stagnant or weakening global economic conditions either in the United States or in other geographic regions may have a material adverse effect on the Company's revenues, operating results and liquidity. The global airline industry is highly competitive and susceptible to price discounting and changes in capacity, which could have a material adverse effect on our business, operating results and financial condition. The airline industry is highly competitive, marked by significant competition with respect to routes, fares, schedules (both timing and frequency), services, products, customer service and frequent flyer programs. Consolidation in the airline industry, the rise of well-funded government sponsored international carriers, changes in international alliances and the creation of immunized JBAs have altered and are expected to continue to alter the competitive landscape in the industry, resulting in the formation of airlines and alliances with increased financial resources, more extensive global networks and services and competitive cost structures. Airlines also compete by increasing or decreasing their capacity, including route systems and the number of destinations served. Several of the Company's domestic and international competitors have increased their international capacity by including service to some destinations that the Company currently serves, causing overlap in destinations served and therefore increasing competition for those destinations. This increased competition in both domestic and international markets may have a material adverse effect on the Company's business, operating results and financial condition. The Company's U.S. operations are subject to competition from traditional network carriers, national point-to-point carriers, and discount carriers, including low-cost carriers and ultra-low-cost carriers. Such carriers may have lower costs and provide service at lower fares to destinations also served by the Company. The significant presence of low-cost carriers, which engage in substantial price discounting, may diminish our ability to achieve sustained profitability on domestic and international routes. Our ability to compete in the domestic market effectively depends, in part, on our ability to maintain a competitive cost structure. If we cannot maintain our costs at a competitive level, then our business, financial condition and operating results could be materially and adversely affected. Our international operations are subject to competition from both foreign and domestic carriers. Competition is significant from government subsidized competitors from certain Middle East countries. These carriers have large numbers of international widebody aircraft on order and are increasing service to the U.S. from their hubs in the Middle East. The government support provided to these carriers has allowed them to grow quickly, reinvest in their product, invest in other airlines and expand their global presence. Through alliance and other marketing and codesharing agreements with foreign carriers, U.S. carriers have increased their ability to sell international transportation, such as services to and beyond traditional European and Asian gateway cities. Similarly, foreign carriers have obtained increased access to interior U.S. passenger traffic beyond traditional U.S. gateway cities through these relationships. In addition, several JBAs among U.S. and foreign carriers have received grants of antitrust immunity allowing the participating carriers to coordinate schedules, pricing, sales and inventory. If we are not able to continue participating in these types of alliance and other marketing and codesharing agreements in the future, our business, financial condition and operating results could be materially and adversely affected. High and/or volatile fuel prices or significant disruptions in the supply of aircraft fuel could have a material adverse impact on the Company's strategic plans, operating results, financial condition and liquidity. Aircraft fuel is critical to the Company's operations and is our single largest operating expense. During the year ended December 31, 2018, the Company's fuel expense was $9.3 billion. The timely and adequate supply of fuel to meet operational demand depends on the continued availability of reliable fuel supply sources, as well as related service and delivery infrastructure. Although the Company has some ability to cover short-term fuel supply and infrastructure disruptions at some major demand locations, it depends significantly on the continued performance of its vendors and service providers to maintain supply integrity. Consequently, the Company can neither predict nor guarantee the continued timely availability of aircraft fuel throughout the Company's system. Aircraft fuel has historically been the Company's most volatile operating expense due to the highly unpredictable nature of market prices for fuel. The Company generally sources fuel at prevailing market prices. Market prices for aircraft fuel have historically fluctuated substantially in short periods of time and continue to be highly volatile due to a dependence on a multitude of unpredictable factors beyond the Company's control. These factors include changes in global crude oil prices, the balance between aircraft fuel supply and demand, natural disasters, prevailing inventory levels and fuel production and transportation infrastructure. Prices of fuel are also impacted by indirect factors, such as geopolitical events, economic growth indicators, fiscal/monetary policies, fuel tax policies, changes in regulations, environmental concerns and financial investments in energy markets. Both actual changes in these factors, as well as changes in market expectations of these factors, can potentially drive rapid changes in fuel price levels in short periods of time. Given the highly competitive nature of the airline industry, the Company may not be able to increase its fares and fees sufficiently to offset the full impact of increases in fuel prices, especially if these increases are significant, rapid and sustained. Further, any such fare or fee increase may not be sustainable, may reduce the general demand for air travel and may also eventually impact the Company's strategic growth and investment plans for the future. In addition, decreases in fuel prices for an extended period of time may result in increased industry capacity, increased competitive actions for market share and lower fares or surcharges in general. If fuel prices were to then subsequently rise quickly, there may be a lag between the rise in fuel prices and any improvement of the revenue environment. To protect against increases in the market prices of fuel, the Company may hedge a portion of its future fuel requirements. The Company does not currently hedge its future fuel requirements. However, to the extent the Company decides to start a hedging program, such hedging program may not be successful in mitigating higher fuel costs, and any price protection provided may be limited due to choice of hedging instruments and market conditions, including breakdown of correlation between hedging instrument and market price of aircraft fuel and failure of hedge counterparties. To the extent that the Company decides to hedge a portion of its future fuel requirements and uses hedge contracts that have the potential to create an obligation to pay upon settlement if fuel prices decline significantly, such hedge contracts may limit the Company's ability to benefit fully from lower fuel costs in the future. If fuel prices decline significantly from the levels existing at the time the Company enters into a hedge contract, the Company may be required to post collateral (margin) beyond certain thresholds. There can be no assurance that the Company's hedging arrangements, if any, will provide any particular level of protection against rises in fuel prices or that its counterparties will be able to perform under the Company's hedging arrangements. Additionally, deterioration in the Company's financial condition could negatively affect its ability to enter into new hedge contracts in the future. The Company relies heavily on technology and automated systems to operate its business and any significant failure or disruption of the technology or these systems could materially harm its business. The Company depends on automated systems and technology to operate its business, including, but not limited to, computerized airline reservation systems, demand prediction software, flight operations systems, revenue management systems, accounting systems, technical and business operations systems, telecommunication systems and commercial websites and applications, including www.united.com and the United Airlines app. United's website and other automated systems must be able to accommodate a high volume of traffic, maintain secure information and deliver important flight and schedule information, as well as process critical financial transactions. These systems could suffer substantial or repeated disruptions due to various events, some of which are beyond the Company's control, including natural disasters, power failures, terrorist attacks, equipment or software failures, computer viruses or cyber security attacks. Substantial or repeated systems failures or disruptions, including failures or disruptions related to the Company's complex integration of systems, could reduce the attractiveness of the Company's services versus those of its competitors, materially impair its ability to market its services and operate its flights, result in the unauthorized release of confidential or otherwise protected information, result in increased costs, lost revenue and the loss or compromise of important data, and may adversely affect the Company's business, operating results and financial condition. The Company's business relies extensively on third-party service providers, including certain technology providers. Failure of these parties to perform as expected, or interruptions in the Company's relationships with these providers or their provision of services to the Company, could have an adverse effect on the Company's business, operating results and financial condition. The Company has engaged third-party service providers to perform a large number of functions that are integral to its business, including regional operations, operation of customer service call centers, distribution and sale of airline seat inventory, provision of information technology infrastructure and services, transmitting or uploading of data, provision of aircraft maintenance and repairs, provision of various utilities, performance of aircraft fueling operations and catering services, among other vital functions and services. The Company does not directly control these third-party service providers, although it does enter into agreements that define expected service performance. Any of these third-party service providers, however, may materially fail to meet its service performance commitments to the Company or may suffer disruptions to its systems that could impact its services. For example, failures in certain third-party technology or communications systems may cause flight delays or cancellations. The failure of any of the Company's third-party service providers to perform its service obligations adequately, or other interruptions of services, may reduce the Company's revenues and increase its expenses, prevent the Company from operating its flights and providing other services to its customers or result in adverse publicity or harm to its brand. In addition, the Company's business and financial performance could be materially harmed if its customers believe that its services are unreliable or unsatisfactory. The Company may also have disagreements with such providers or such contracts may be terminated or may not be extended or renewed. For example, the number of flight reservations booked through third-party GDSs or online travel agents ("OTAs") may be adversely affected by disruptions in the business relationships between the Company and these suppliers. Such disruptions, including a failure to agree upon acceptable contract terms when contracts expire or otherwise become subject to renegotiation, may cause the Company's flight information to be limited or unavailable for display by the affected GDS or OTA operator, significantly increase fees for both the Company and GDS/OTA users and impair the Company's relationships with its customers and travel agencies. Any such disruptions or contract terminations may adversely impact our operations and financial results. If we are not able to negotiate or renew agreements with third-party service providers, or if we renew existing agreements on less favorable terms, our operations and financial results may be adversely affected. The Company could experience adverse publicity, harm to its brand, reduced travel demand and potential tort liability as a result of an accident, catastrophe or incident involving its aircraft or its operations, the aircraft or operations of its regional carriers, the aircraft or operations of its codeshare partners, or the aircraft or operations of another airline, which may result in a material adverse effect on the Company's business, operating results and financial condition. An accident, catastrophe or incident involving an aircraft that the Company operates, or an aircraft that is operated by a codeshare partner, one of the Company's regional carriers or another airline, or an incident involving the Company's operations, or the operations of a codeshare partner, one of the Company's regional carriers or of another airline, could have a material adverse effect on the Company if such accident, catastrophe or incident created a public perception that the Company's operations, or the operations of its codeshare partners or regional carriers, are not safe or reliable, or are less safe or reliable than other airlines. Such public perception could, in turn, result in adverse publicity for the Company, cause harm to the Company's brand and reduce travel demand on the Company's flights, or the flights of its codeshare partners or regional carriers. In addition, any such accident, catastrophe or incident involving the Company, its regional carriers or its codeshare partners could expose the Company to significant tort liability. Although the Company currently maintains liability insurance in amounts and of the type the Company believes to be consistent with industry practice to cover damages arising from any such accident, catastrophe or incident, and the Company's codeshare partners and regional carriers carry similar insurance and generally indemnify the Company for their operations, if the Company's liability exceeds the applicable policy limits or the ability of another carrier to indemnify it, the Company could incur substantial losses from an accident, catastrophe or incident which may result in a material adverse effect on the Company's operating results and financial condition. Terrorist attacks, international hostilities or other security events, or the fear of terrorist attacks or hostilities, even if not made directly on the airline industry, could negatively affect the Company and the airline industry. Terrorist attacks or international hostilities, even if not made on or targeted directly at the airline industry, or the fear of or the precautions taken in anticipation of such attacks (including elevated national threat warnings, travel restrictions, selective cancellation or redirection of flights and new security regulations) could materially and adversely affect the Company and the airline industry. Security events pose a significant risk to our passenger and cargo operations. These events could include acts of violence in public areas that we cannot control. The Company's financial resources may not be sufficient to absorb the adverse effects of any future terrorist attacks, international hostilities or other security events. Any such events could have a material adverse impact on the Company's financial condition, liquidity and operating results. Increasing privacy and data security obligations or a significant data breach may adversely affect the Company's business. The Company is subject to increasing legislative, regulatory and customer focus on privacy issues and data security. Also, a number of the Company's commercial partners, including credit card companies, have imposed data security standards that the Company must meet. These standards continue to evolve. The Company will continue its efforts to meet its privacy and data security obligations; however, it is possible that certain new obligations may be difficult to meet and could increase the Company's costs. Additionally, the Company must manage evolving cybersecurity risks. Our network systems and storage applications, and those systems and storage and other business applications maintained by our third-party providers, may be subject to attempts to gain unauthorized access, breach, malfeasance or other system disruptions. In some cases, it is difficult to anticipate or to detect immediately such incidents and the damage caused thereby. While we continually work to safeguard our internal network systems and validate the security of our third-party providers, including through information security policies and employee awareness and training, there is no assurance that such actions will be sufficient to prevent cyber-attacks or security breaches. The loss, disclosure, misappropriation of or access to customers', employees' or business partners' information or the Company's failure to meet its obligations could result in legal claims or proceedings, penalties and remediation costs. A significant data breach or the Company's failure to meet its obligations may adversely affect the Company's reputation, business, operating results and financial condition. Disruptions to our regional network and United Express flights provided by third-party regional carriers could adversely affect our business, operating results and financial condition. The Company has contractual relationships with various regional carriers to provide regional aircraft service branded as United Express. These regional operations are an extension of the Company's mainline network and complement the Company's operations by carrying traffic that connects to mainline service and allows flights to smaller cities that cannot be provided economically with mainline aircraft. The Company's business and operations are dependent on its regional flight network, with regional capacity accounting for approximately 11% of the Company's total capacity for the year ended December 31, 2018. Although the Company has agreements with its regional carriers that include contractually agreed performance metrics, each regional carrier is a separately certificated commercial air carrier and the Company does not control the operations of these carriers. A number of factors may impact the Company's regional network, including weather-related effects and seasonality. In addition, the decrease in qualified pilots driven by changes to federal regulations has adversely impacted and could continue to affect the Company's regional flying. For example, the FAA's expansion of minimum pilot qualification standards, including a requirement that a pilot have at least 1,500 total flight hours, as well as the FAA's revised pilot flight and duty time requirements under Part 117 of the Federal Aviation Regulations, have contributed to a smaller supply of pilots available to regional carriers. The decrease in qualified pilots resulting from the regulations as well as factors including a decreased student pilot population and a shrinking U.S. military from which to hire qualified pilots, could adversely impact the Company's operations and financial condition, and could also require the Company to reduce regional carrier flying. If a significant disruption occurs to the Company's regional network or flights or if one or more of the regional carriers with which the Company has relationships is unable to perform their obligations over an extended period of time, there could be a material adverse effect on the Company's business, financial condition and operating results. Current or future litigation and regulatory actions, or failure to comply with the terms of any settlement, order or arrangement relating to these actions, could have a material adverse impact on the Company. From time to time, we are subject to litigation and other legal and regulatory proceedings relating to our business or investigations or other actions by governmental agencies, including as described in Part I, Item 3, Legal Proceedings, of this report. No assurances can be given that the results of these or new matters will be favorable to us. An adverse resolution of lawsuits, arbitrations, investigations or other proceedings or actions could have a material adverse effect on our financial condition and operating results, including as a result of non-monetary remedies, and could also result in adverse publicity. Defending ourselves in these matters may be time-consuming, expensive and disruptive to normal business operations and may result in significant expense and a diversion of management's time and attention from the operation of our business, which could impede our ability to achieve our business objectives. Additionally, any amount that we may be required to pay to satisfy a judgment, settlement, fine or penalty may not be covered by insurance. If we fail to comply with the terms contained in any settlement, order or agreement with a governmental authority relating to these matters, we could be subject to criminal or civil penalties, which could have a material adverse impact on the Company. Under our charter and certain indemnification agreements that we have entered into (and may in the future enter into) with our officers, directors and certain third parties, we could be required to indemnify and advance expenses to them in connection with their involvement in certain actions, suits, investigations and other proceedings. There can be no assurance that any of these payments will not be material. Our significant investments in other airlines, including in other parts of the world, and the commercial relationships that we have with those carriers may not produce the returns or results we expect. An important part of our strategy to expand our global network includes making significant investments in airlines in other parts of the world and expanding our commercial relationships with these carriers. For example, in November 2018, United entered into a revenue-sharing joint business agreement with Avianca, Copa and several of their respective affiliates, subject to regulatory approval. Concurrently with this transaction, United advanced a loan of $456 million to affiliates of Synergy Aerospace Corporation ("Synergy"), the majority shareholder of Avianca Holdings S.A. ("AVH"), the parent company of Avianca, and entered into certain other related agreements, including a put arrangement with Avianca's significant minority shareholder, Kingsland Holdings Limited ("Kingsland"). The loan is secured by a pledge of Synergy's equity and Synergy's shares of AVH stock, and the loan and other agreements contain several provisions whereby the Company may acquire AVH stock. We also have an equity investment in Azul. See Note 9 to the financial statements included in Part II, Item 8 of this report for additional information regarding our investments in Avianca and Azul. We also have investments in several domestic regional airlines. In January 2019, we completed the acquisition of a 49.9% interest in ManaAir LLC, which, as of immediately following the closing of that investment, owns 100% of the equity interests in ExpressJet Airlines, Inc., a domestic regional airline. We also have minority equity interests in CommutAir and Republic Airways Holdings, Inc. See Note 9 to the financial statements included in Part II, Item 8 of this report for additional information regarding our investments in regional airlines. We expect to continue exploring similar non-controlling investments in, and entering into JBAs, commercial agreements, loan transactions and strategic alliances with, other carriers as part of our regional and global business strategy. These transactions and relationships involve significant challenges and risks. We are dependent on these other carriers for significant aspects of our network in the regions in which they operate. While we work closely with these carriers, each is a separately certificated commercial air carrier and we do not have control over their operations, strategy, management or business methods. These airlines also are subject to a number of the same risks as our business, which are described in this Item 1A., Risk Factors, including competitive pressures on pricing, demand and capacity; changes in aircraft fuel pricing; and the impact of global and local political and economic conditions on operations and customer travel patterns, among others. As a result of these and other factors, we may not realize a satisfactory return on our investment, and we may not receive repayment of any invested or loaned funds. Further, these investments may not generate the revenue or operational synergies we expect, and they may distract management focus from our operations or other strategic options. Finally, our reliance on these other carriers in the regions in which they operate may negatively impact our regional and global operations and results if those carriers are impacted by general business risks or perform below our expectations or needs. Any one or more of these events could have a material adverse effect on our operating results or financial condition. We may also be subject to consequences from any improper behavior of JBA partners, including for failure to comply with anti-corruption laws such as the U.S. Foreign Corrupt Practices Act. Furthermore, our relationships with these carriers may be subject to the laws and regulations of non-U.S. jurisdictions in which these carriers are located or conduct business. Any political or regulatory change in these jurisdictions that negatively impact or prohibit our arrangements with these carriers could have an adverse effect on our operating results or financial condition. To the extent that the operations of any of these carriers are disrupted over an extended period of time or their actions subject us to the consequences of failure to comply with laws and regulations, our operating results may be adversely affected. The airline industry may undergo further change with respect to alliances and JBAs or due to consolidations, any of which could have a material adverse effect on the Company. The Company faces and may continue to face strong competition from other carriers due to the modification of alliances and formation of new JBAs. Carriers may improve their competitive positions through airline alliances, slot swaps and/or JBAs. Certain types of airline JBAs further competition by allowing multiple airlines to coordinate routes, pool revenues and costs, and enjoy other mutual benefits, achieving many of the benefits of consolidation. Open Skies agreements, including the longstanding agreements between the United States and each of the EU, Canada, Japan, Korea, New Zealand, Australia, Colombia and Panama, as well as the more recent agreements between the United States and each of Mexico and Brazil, may also give rise to better integration opportunities among international carriers. Movement of airlines between current global airline alliances could reduce joint network coverage for members of such alliances while also creating opportunities for JBAs and bilateral alliances that did not exist before such realignment. Further airline and airline alliance consolidations or reorganizations could occur in the future. The Company routinely engages in analyses and discussions regarding its own strategic position, including current and potential alliances, asset acquisitions and divestitures and may have future discussions with other airlines regarding strategic activities. If other airlines participate in such activities, those airlines may significantly improve their cost structures or revenue generation capabilities, thereby potentially making them stronger competitors of the Company and potentially impairing the Company's ability to realize expected benefits from its own strategic relationships. Orders for new aircraft typically must be placed years in advance of scheduled deliveries, and changes in the Company's network strategy over time may make aircraft on order less economic for the Company, result in costs related to modification or termination of aircraft orders or cause the Company to enter into orders for new aircraft on less favorable terms. The Company's orders for new aircraft are typically made years in advance of actual delivery of such aircraft, and the financial commitment required for purchases of new aircraft is substantial. At December 31, 2018, the Company had firm commitments to purchase 273 new aircraft from The Boeing Company ("Boeing"), Airbus S.A.S ("Airbus") and Embraer S.A. ("Embraer"), as well as related agreements with engine manufacturers, maintenance providers and others. As of December 31, 2018, the Company's commitments relating to the acquisition of aircraft and related spare engines, aircraft improvements and other related obligations aggregated to a total of $24.7 billion. Subsequent to the Company placing an order for new aircraft, the Company's network strategy may change. As a result, the Company's preference for a particular aircraft that it has ordered, often years in advance, may be decreased or eliminated. If the Company were to modify or terminate any of its existing aircraft order commitments, it may be responsible for material liabilities to its counterparties arising from any such change. Additionally, the Company may have a need for additional aircraft that are not available under its existing orders. In such cases, the Company may seek to acquire aircraft from other sources, such as through lease arrangements, which may result in higher costs or less favorable terms, or through the purchase or lease of used aircraft. The Company may not be able to acquire such aircraft when needed on favorable terms or at all. A majority of the Company's aircraft and certain parts are sourced from single suppliers; therefore, the Company would be materially and adversely affected if it were unable to obtain additional equipment or support from any of these suppliers. The Company currently sources the majority of its aircraft and many related aircraft parts from Boeing. In addition, our aircraft suppliers are dependent on other suppliers for certain other aircraft parts. Therefore, if the Company was unable to acquire additional aircraft from Boeing, or if Boeing was unable or unwilling to make timely deliveries of aircraft or to provide adequate support for its products, the Company's operations could be materially and adversely affected. The Company is also dependent on a limited number of suppliers for aircraft engines and certain other aircraft parts and could therefore also be materially and adversely affected in the event of the unavailability of these engines and other parts. Union disputes, employee strikes or slowdowns, and other labor-related disruptions could adversely affect the Company's operations and could result in increased costs that impair its financial performance. United is a highly unionized company. As of December 31, 2018, the Company and its subsidiaries had approximately 92,000 active employees, of whom approximately 83% were represented by various U.S. labor organizations. There is a risk that unions or individual employees might pursue judicial or arbitral claims arising out of changes implemented as a result of the Company entering into collective bargaining agreements with its represented employee groups. There is also a possibility that employees or unions could engage in job actions such as slowdowns, work-to-rule campaigns, sick-outs or other actions designed to disrupt the Company's normal operations, in an attempt to pressure the Company in collective bargaining negotiations. Although the RLA makes such actions unlawful until the parties have been lawfully released to self-help, and the Company can seek injunctive relief against premature self-help, such actions can cause significant harm even if ultimately enjoined. In addition, collective bargaining agreements with the Company's represented employee groups increase the Company's labor costs, which increase could be material for any applicable reporting period. An outbreak of a disease or similar public health threat could have a material adverse impact on the Company's business, operating results and financial condition. An outbreak of a disease or similar public health threat that affects travel demand, travel behavior, or travel restrictions could have a material adverse impact on the Company's business, financial condition and operating results. If we experience changes in, or are unable to retain, our senior management team or other key employees, our operating results could be adversely affected. Much of our future success depends on the continued availability of skilled personnel with industry experience and knowledge, including our senior management team and other key employees. If we are unable to attract and retain talented, highly qualified senior management and other key employees, or if we are unable to effectively provide for the succession of senior management, our business may be adversely affected. Extended interruptions or disruptions in service at major airports where we operate could have a material adverse impact on our operations. The airline industry is heavily dependent on business models that concentrate operations in major airports in the United States and throughout the world. An extended interruption or disruption at an airport where we have significant operations could have a material impact on our business, financial condition and results of operation. We operate principally through our domestic hubs in at Newark, Chicago O'Hare, Denver, Houston Bush, LAX, Guam, SFO and Washington Dulles. Substantially all of our flights either originate in or fly into one of these locations. A significant interruption or disruption in service at one of our hubs or other airports where we have a significant presence resulting from ATC delays, weather conditions, natural disasters, growth constraints, relations with third-party service providers, failure of computer systems, disruptions to government agencies or personnel, disruptions at airport facilities or other key facilities used by us to manage our operations, labor relations, power supplies, fuel supplies, terrorist activities, international hostilities or otherwise could result in the cancellation or delay of a significant portion of our flights and, as a result, could have a material impact on our business, operating results and financial condition. We have minimal control over the operation, quality or maintenance of these services or whether vendors will improve or continue to provide services that are essential to our business. The airline industry is subject to extensive government regulation, which imposes significant costs and may adversely impact our business, operating results and financial condition. Airlines are subject to extensive regulatory and legal oversight. Compliance with U.S. and international regulations imposes significant costs and may have adverse effects on the Company. Laws, regulations, taxes and airport rates and charges, both domestically and internationally, have been proposed from time to time that could significantly increase the cost of airline operations or reduce airline revenue. United provides air transportation under certificates of public convenience and necessity issued by the DOT. If the DOT altered, amended, modified, suspended or revoked these certificates, it could have a material adverse effect on the Company's business. The FAA regulates the safety of United's operations. United operates pursuant to an air carrier operating certificate issued by the FAA. The FAA's regulations include stringent pilot flight and duty time requirements under Part 117 of the Federal Aviation Regulations, as well as minimum qualifications for air carrier first officers. These regulations have caused mainline airlines to hire regional pilots, while simultaneously significantly reducing the pool of new pilots from which regional carriers themselves can hire. Although this is an industry issue, it directly affects the Company and has required it to reduce regional partner flying, as several regional partners have experienced difficulty flying their schedules due to reduced pilot availability. From time to time, the FAA also issues orders, airworthiness directives and other regulations relating to the maintenance and operation of aircraft that require material expenditures or operational restrictions by the Company. These FAA orders and directives could include the temporary grounding of an entire aircraft type if the FAA identifies design, manufacturing, maintenance or other issues requiring immediate corrective action. These FAA directives or requirements could have a material adverse effect on the Company. In 2018, the U.S. Congress approved a five-year reauthorization for the FAA, which encompasses significant aviation tax and policy-related issues. The law includes a range of policy changes related to airline customer service and aviation safety which, depending on how they are implemented, could impact our operations and costs. Additionally, the U.S. Congress may fail to continue to fund the operations of one or more federal government agencies which could negatively impact the Company and the airline industry. The Company's operations may also be adversely impacted due to the existing antiquated ATC system utilized by the U.S. government and regulated by the FAA. During peak travel periods in certain markets, the current ATC system's inability to handle demand has led to short-term capacity constraints imposed by government agencies and resulted in delays and disruptions of air traffic. In addition, the current system will not be able to effectively handle projected future air traffic growth. The outdated technologies also cause the ATC to be less resilient in the event of a failure, causing flight cancellations and delays. Imposition of these ATC constraints on a long-term basis may have a material adverse effect on the Company's operations. Failure to update the ATC system in a timely manner, and the substantial funding requirements of a modernized ATC system that may be imposed on air carriers may have an adverse impact on the Company's financial condition or operating results. Access to landing and take-off rights, or "slots," at several major U.S. airports and many foreign airports served by the Company are, or recently have been, subject to government regulation. Certain of the Company's major hubs are among the most congested airports in the United States and have been or could be the subject of regulatory action that might limit the number of flights and/or increase costs of operations at certain times or throughout the day. The FAA may limit the Company's airport access by limiting the number of departure and arrival slots at high density traffic airports, which could affect the Company's ownership and transfer rights, and local airport authorities may have the ability to control access to certain facilities or the cost of access to their facilities, which could have an adverse effect on the Company's business. The FAA historically has taken actions with respect to airlines' slot holdings that airlines have challenged; if the FAA were to take actions that adversely affect the Company's slot holdings, the Company could incur substantial costs to preserve its slots or may lose slots. If slots are eliminated at an airport, or if the number of hours of operation governed by slots is reduced at an airport, the lack of controls on takeoffs and landings could result in greater congestion both at the affected airport or in the regional airspace (e.g., the New York City metropolitan region airspace) and could significantly impact the Company's operations. Further, the Company's operating costs at airports, including the Company's major hubs, may increase significantly because of capital improvements at such airports that the Company may be required to fund, directly or indirectly. Such costs could be imposed by the relevant airport authority without the Company's approval and may have a material adverse effect on the Company's financial condition. The ability of carriers to operate flights on international routes between the United States and other countries is highly regulated. Applicable arrangements between the United States and foreign governments may be amended from time to time, government policies with respect to airport operations may be revised, and the availability of appropriate slots or facilities may change. The Company currently operates a number of flights on international routes under government arrangements, regulations or policies that designate the number of carriers permitted to operate on such routes, the capacity of the carriers providing services on such routes, the airports at which carriers may operate international flights, or the number of carriers allowed access to particular airports. Any limitations, additions or modifications to such arrangements, regulations or policies could have a material adverse effect on the Company's financial condition and operating results. Additionally, a change in law, regulation or policy for any of the Company's international routes, such as Open Skies, could have a material adverse impact on the Company's financial condition and operating results and could result in the impairment of material amounts of related tangible and intangible assets. In addition, competition from revenue-sharing JBAs and other alliance arrangements by and among other airlines could impair the value of the Company's business and assets on the Open Skies routes. The Company's plans to enter into or expand U.S. antitrust immunized alliances and JBAs on various international routes are subject to receipt of approvals from applicable U.S. federal authorities and obtaining other applicable foreign government clearances or satisfying the necessary applicable regulatory requirements. There can be no assurance that such approvals and clearances will be granted or will continue in effect upon further regulatory review or that changes in regulatory requirements or standards can be satisfied. See Part I, Item 1, Business-Industry Regulation, of this report for additional information on government regulation impacting the Company. We are subject to many forms of environmental regulation and liability and risks associated with climate change, and may incur substantial costs as a result. Many aspects of the Company's operations are subject to increasingly stringent federal, state, local and international laws protecting the environment, including those relating to emissions to the air, water discharges, safe drinking water and the use and management of hazardous materials and wastes. Compliance with existing and future environmental laws and regulations can require significant expenditures and violations can lead to significant fines and penalties. In addition, from time to time we are identified as a responsible party for environmental investigation and remediation costs under applicable environmental laws due to the disposal of hazardous substances generated by our operations. We could also be subject to environmental liability claims from various parties, including airport authorities, related to our operations at our leased premises or the off-site disposal of waste generated at our facilities. We may incur substantial costs as a result of changes in weather patterns due to climate change. Increases in the frequency, severity or duration of severe weather events such as thunderstorms, hurricanes, flooding, typhoons, tornados and other severe weather events could result in increases in delays and cancellations, turbulence-related injuries and fuel consumption to avoid such weather, any of which could result in significant loss of revenue and higher costs. To address climate change risks, CORSIA has been developed by ICAO, a UN specialized agency. CORSIA is intended to create a single global market-based measure to achieve carbon-neutral growth for international aviation after 2020 through airline purchases of carbon offset credits. Certain CORSIA program details remain to be developed and could potentially be affected by political developments in participating countries or the results of the pilot phase of the program, and thus the impact of CORSIA cannot be fully predicted. However, CORSIA is expected to increase operating costs for airlines that operate internationally. In addition to CORSIA, the EPA had begun preliminary work to adopt its own aircraft engine GHG emission standards which were expected to be aligned with recent ICAO carbon dioxide emission standards. The timing of any U.S. EPA aircraft engine GHG emission standards is currently unknown, but some jurisdictions in which United operates have adopted or are considering GHG emission reduction initiatives, which could impact various aspects of the Company's business. The precise nature of future requirements and their applicability to the Company are difficult to predict, but the financial impact to the Company and the aviation industry would likely be adverse and could be significant. See Part I, Item 1, Business-Industry Regulation-Environmental Regulation, of this report for additional information on environmental regulation impacting the Company. The United Kingdom's withdrawal from the EU may adversely impact our operations in the United Kingdom and elsewhere. In June 2016, United Kingdom ("UK") voters approved an advisory referendum for the UK to exit the EU. The UK parliament voted in favor of allowing the government to commence negotiations to determine the future terms of the UK's relationship with the EU, including the terms of trade between the UK and the EU and other nations. The timing of the proposed exit is currently scheduled for March 29, 2019, with a transition period potentially running through December 2020. A withdrawal plan was presented to the UK parliament in January 2019 and rejected, creating further uncertainty in negotiations and the process of withdrawal. Depending on the outcome of these negotiations, we could face new challenges in our operations, such as instability in global financial and foreign exchange markets. This instability could include volatility in the value of the British pound and European euro, additional travel restrictions on passengers traveling between the UK and other EU countries, changes to the legal status of EU-resident employees, legal uncertainty and potentially divergent national laws and regulations. At this time, we cannot predict the impact that an actual exit from the EU will have on our business generally and our UK and European operations more specifically, and no assurance can be given that our operating results, financial condition and prospects would not be adversely impacted by the result. The Company's operating results fluctuate due to seasonality and other factors associated with the airline industry, many of which are beyond the Company's control. Due to greater demand for air travel during the spring and summer months, revenues in the airline industry in the second and third quarters of the year are generally stronger than revenues in the first and fourth quarters of the year, which are periods of lower travel demand. The Company's operating results generally reflect this seasonality, but have also been impacted by numerous other factors that are not necessarily seasonal, including, among others, extreme or severe weather, outbreaks of disease or pandemics, ATC congestion, geological events, political instability, terrorism, natural disasters, changes in the competitive environment due to industry consolidation, tax obligations, general economic conditions and other factors. As a result, the Company's quarterly operating results are not necessarily indicative of operating results for an entire year and historical operating results in a quarterly or annual period are not necessarily indicative of future operating results. Increases in insurance costs or inadequate insurance coverage may materially and adversely impact our business, operating results and financial condition. The Company could be exposed to significant liability or loss if its property or operations were to be affected by a natural catastrophe or other event, including aircraft accidents. The Company maintains insurance policies, including, but not limited to, terrorism, aviation hull and liability, workers' compensation and property and business interruption insurance, but we are not fully insured against all potential hazards and risks incident to our business. If the Company is unable to obtain sufficient insurance with acceptable terms, the costs of such insurance increase materially, or if the coverage obtained is insufficient relative to actual liability or losses that the Company experiences, whether due to insurance market conditions, policy limitations and exclusions or otherwise, its operating results and financial condition could be materially and adversely affected. The Company has a significant amount of financial leverage from fixed obligations, and insufficient liquidity may have a material adverse effect on the Company's financial condition and business. The Company has a significant amount of financial leverage from fixed obligations, including aircraft lease and debt financings, leases of airport property and other facilities, and other material cash obligations. In addition, the Company has substantial noncancelable commitments for capital expenditures, including for the acquisition of new aircraft and related spare engines. Although the Company's cash flows from operations and its available capital, including the proceeds from financing transactions, have been sufficient to meet these obligations and commitments to date, the Company's future liquidity could be negatively affected by the risk factors discussed in this report. If the Company's liquidity is materially diminished, the Company might not be able to timely pay its leases and debts or comply with certain operating and financial covenants under its financing and credit card processing agreements or with other material provisions of its contractual obligations. The Company's substantial level of indebtedness and non-investment grade credit rating, as well as market conditions and the availability of assets as collateral for loans or other indebtedness, may make it difficult for the Company to raise additional capital if needed to meet its liquidity needs on acceptable terms, or at all. In addition, our variable rate indebtedness may use London interbank offered rates ("LIBOR") as a benchmark for establishing the rate. As announced in July 2017, LIBOR is expected to be phased out by the end of 2021. Uncertainty as to the nature of alternative reference rates and as to potential changes or other reforms to LIBOR may adversely impact the availability and cost of borrowings. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, of this report for additional information regarding the Company's liquidity. Agreements governing our debt include financial and other covenants. Failure to comply with these covenants could result in events of default. Our financing agreements include various financial and other covenants. Certain of these covenants require UAL or United, as applicable, to maintain minimum liquidity and/or minimum collateral coverage ratios. UAL's or United's ability to comply with these covenants may be affected by events beyond its control, including the overall industry revenue environment, the level of fuel costs and the appraised value of the collateral. In addition, our financing agreements contain other negative covenants customary for such financings. These covenants are subject to important exceptions and qualifications. If we fail to comply with these covenants and are unable to remedy or obtain a waiver or amendment, an event of default would result. If an event of default were to occur, the lenders could, among other things, declare outstanding amounts due and payable. In addition, an event of default or declaration of acceleration under one financing agreement could also result in an event of default under other of our financing agreements due to cross-default and cross-acceleration provisions. The acceleration of significant amounts of debt could require us to renegotiate, repay or refinance the obligations under our financing arrangements. The Company may never realize the full value of its intangible assets or its long-lived assets causing it to record impairments that may negatively affect its financial condition and operating results. In accordance with applicable accounting standards, the Company is required to test its indefinite-lived intangible assets for impairment on an annual basis, or more frequently where there is an indication of impairment. In addition, the Company is required to test certain of its other assets for impairment where there is any indication that an asset may be impaired. The Company may be required to recognize losses in the future due to, among other factors, extreme fuel price volatility, tight credit markets, government regulatory changes, decline in the fair values of certain tangible or intangible assets, such as aircraft, route authorities, airport slots and frequent flyer database, unfavorable trends in historical or forecasted results of operations and cash flows and an uncertain economic environment, as well as other uncertainties. The Company can provide no assurance that a material impairment loss of tangible or intangible assets will not occur in a future period. The value of the Company's aircraft could be impacted in future periods by changes in supply and demand for these aircraft. Such changes in supply and demand for certain aircraft types could result from grounding of aircraft by the Company or other carriers. An impairment loss could have a material adverse effect on the Company's financial condition and operating results. ITEM 1B.

ITEM 1A. RISK FACTORS. The following risk factors should be read carefully when evaluating the Company's business and the forward-looking statements contained in this report and other statements the Company or its representatives make from time to time. Any of the following risks could materially and adversely affect the Company's business, operating results, financial condition and the actual outcome of matters as to which forward-looking statements are made in this report. If we do not successfully execute our strategic operating plan, or if our strategic operating plan is unsuccessful, our business, operating results and financial condition could be materially and adversely affected. We have announced several strategic plans in recent years, including several revenue-generating initiatives and plans to optimize our revenue, such as our plans to add capacity, including international expansion and new or increased service to mid-size airports, and initiatives and plans to optimize and control our costs. We also continue to explore opportunities to enhance our segmentation, including the introduction of Polaris, Basic Economy and United Premium Plus, and are implementing many programs and policies to improve the customer experience at all points in air travel. In developing our strategic operating plan, we make certain assumptions, including, but not limited to, those related to customer demand, competition, market consolidation, the availability of aircraft and the global economy. Actual economic, market and other conditions may be different from our assumptions. In 2019, our capacity growth was lower than planned due to the grounding of Boeing 737 MAX aircraft, among other factors, which adversely impacted our ability to execute our strategic operating plans. If we do not successfully execute our strategic operating plan, or if actual results vary significantly from our assumptions, our business, operating results and financial condition could be materially and adversely impacted. Unfavorable economic and political conditions, in the United States and globally, may have a material adverse effect on our business, operating results and financial condition. The Company's business and operating results are significantly impacted by U.S. and global economic and political conditions. The airline industry is highly cyclical, and the level of demand for air travel is correlated to the strength of the U.S. and global economies. Robust demand for the Company's air transportation services depends largely on favorable economic conditions, including the strength of the domestic and foreign economies, low unemployment levels, strong consumer confidence levels and the availability of consumer and business credit. Air transportation is often a discretionary purchase that leisure travelers may limit or eliminate during difficult economic times. Short-haul travelers, in particular, have the option to replace air travel with surface travel. In addition, during periods of unfavorable economic conditions, business travelers historically have reduced the volume of their travel, either due to cost-saving initiatives, the replacement of travel with alternatives such as videoconferencing, or as a result of decreased business activity requiring travel. During such periods, the Company's business and operating results may be adversely affected due to significant declines in industry passenger demand, particularly with respect to the Company's business and premium cabin travelers, and a reduction in fare levels. As a global business with operations outside of the United States from which it derives significant operating revenues, volatile conditions in certain international regions may have a negative impact on the Company's operating results and its ability to achieve its business objectives. The Company's international operations are a vital part of its worldwide airline network. Political disruptions and instability in certain regions can negatively impact the demand and network availability for air travel. Additionally, any deterioration in global trade relations, such as increased tariffs or other trade barriers, could result in a decrease in the demand for international air travel. Stagnant or weakening global economic conditions either in the United States or in other geographic regions may have a material adverse effect on the Company's revenues, operating results and liquidity. The global airline industry is highly competitive and susceptible to price discounting and changes in capacity, which could have a material adverse effect on our business, operating results and financial condition. The airline industry is highly competitive, marked by significant competition with respect to routes, fares, schedules (both timing and frequency), services, products, customer service and frequent flyer programs. Consolidation in the airline industry, the rise of well-funded government sponsored international carriers, changes in international alliances and the creation of immunized JBAs have altered and are expected to continue to alter the competitive landscape in the industry, resulting in the formation of airlines and alliances with increased financial resources, more extensive global networks and services and competitive cost structures. Airlines also compete by increasing or decreasing their capacity, including route systems and the number of destinations served. Several of the Company's domestic and international competitors have increased their international capacity by including service to some destinations that the Company currently serves, causing overlap in destinations served, and therefore, increasing competition for those destinations. This increased competition in both domestic and international markets may have a material adverse effect on the Company's business, operating results and financial condition. The Company's U.S. operations are subject to competition from traditional network carriers, national point-to-point carriers, and discount carriers, including low-cost carriers and ultra-low-cost carriers. Such carriers may have lower costs and provide service at lower fares to destinations also served by the Company. The significant presence of low-cost carriers and ultra-low-cost carriers, which engage in substantial price discounting, may diminish our ability to achieve sustained profitability on domestic and international routes. Our ability to compete in the domestic market effectively depends, in part, on our ability to maintain a competitive cost structure. If we cannot maintain our costs at a competitive level, then our business, operating results and financial condition could be materially and adversely affected. Our international operations are subject to competition from both foreign and domestic carriers. Competition is significant from government subsidized competitors from certain Middle East countries. These carriers have large numbers of international widebody aircraft on order and are increasing service to the U.S. from their hubs in the Middle East. The government support provided to these carriers has allowed them to grow quickly, reinvest in their product, invest in other airlines and expand their global presence. We also face competition from foreign carriers operating under "fifth freedom" rights permitted under international treaties that allow certain carriers to provide service to and from stopover points between their home country and ultimate destination, including points in the United States, in competition with service provided by us. Through alliance and other marketing and codesharing agreements with foreign carriers, U.S. carriers have increased their ability to sell international transportation, such as services to and beyond traditional global gateway cities. Similarly, foreign carriers have obtained increased access to interior U.S. passenger traffic beyond traditional U.S. gateway cities through these relationships. In addition, several JBAs among U.S. and foreign carriers have received grants of antitrust immunity allowing the participating carriers to coordinate schedules, pricing, sales and inventory. If we are not able to continue participating in these types of alliance and other marketing and codesharing agreements in the future, our business, operating results and financial condition could be materially and adversely affected. High and/or volatile fuel prices or significant disruptions in the supply of aircraft fuel could have a material adverse impact on the Company's strategic plans, operating results, financial condition and liquidity. Aircraft fuel is critical to the Company's operations and is one of our largest operating expenses. During the year ended December 31, 2019, the Company's fuel expense was approximately $9.0 billion. The timely and adequate supply of fuel to meet operational demand depends on the continued availability of reliable fuel supply sources, as well as related service and delivery infrastructure. Although the Company has some ability to cover short-term fuel supply and infrastructure disruptions at some major demand locations, it depends significantly on the continued performance of its vendors and service providers to maintain supply integrity. Consequently, the Company can neither predict nor guarantee the continued timely availability of aircraft fuel throughout the Company's system. Aircraft fuel has historically been the Company's most volatile operating expense due to the highly unpredictable nature of market prices for fuel. The Company generally sources fuel at prevailing market prices. Market prices for aircraft fuel have historically fluctuated substantially in short periods of time and continue to be highly volatile due to a dependence on a multitude of unpredictable factors beyond the Company's control. These factors include changes in global crude oil prices, the balance between aircraft fuel supply and demand, natural disasters, prevailing inventory levels and fuel production and transportation infrastructure. Prices of fuel are also impacted by indirect factors, such as geopolitical events, economic growth indicators, fiscal/monetary policies, fuel tax policies, changes in regulations, environmental concerns and financial investments in energy markets. Both actual changes in these factors, as well as changes in related market expectations, can potentially drive rapid changes in fuel prices in short periods of time. Given the highly competitive nature of the airline industry, the Company may not be able to increase its fares and fees sufficiently to offset the full impact of increases in fuel prices, especially if these increases are significant, rapid and sustained. Further, any such fare or fee increase may not be sustainable, may reduce the general demand for air travel and may also eventually impact the Company's strategic growth and investment plans for the future. In addition, decreases in fuel prices for an extended period of time may result in increased industry capacity, increased competitive actions for market share and lower fares or surcharges. If fuel prices were to then subsequently rise quickly, there may be a lag between the rise in fuel prices and any improvement of the revenue environment. To protect against increases in the market prices of fuel, the Company may hedge a portion of its future fuel requirements. The Company does not currently hedge its future fuel requirements. However, to the extent the Company decides to start a hedging program, such hedging program may not be successful in mitigating higher fuel costs, and any price protection provided may be limited due to the choice of hedging instruments and market conditions, including breakdown of correlation between hedging instrument and market price of aircraft fuel and failure of hedge counterparties. To the extent that the Company decides to hedge a portion of its future fuel requirements and uses hedge contracts that have the potential to create an obligation to pay upon settlement if fuel prices decline significantly, such hedge contracts may limit the Company's ability to benefit fully from lower fuel prices in the future. If fuel prices decline significantly from the levels existing at the time the Company enters into a hedge contract, the Company may be required to post collateral (margin) beyond certain thresholds. There can be no assurance that the Company's hedging arrangements, if any, will provide any particular level of protection against rises in fuel prices or that its counterparties will be able to perform under the Company's hedging arrangements. Additionally, deterioration in the Company's financial condition could negatively affect its ability to enter into new hedge contracts in the future. The Company relies heavily on technology and automated systems to operate its business and any significant failure or disruption of the technology or these systems could materially harm its business. The Company depends on automated systems and technology to operate its business, including, but not limited to, computerized airline reservation systems, demand prediction software, flight operations systems, revenue management systems, accounting systems, technical and business operations systems, telecommunication systems and commercial websites and applications, including www.united.com and the United Airlines app. United's website and other automated systems must be able to accommodate a high volume of traffic, maintain secure information and deliver important flight and schedule information, as well as process critical financial transactions. These systems could suffer substantial or repeated disruptions due to various events, some of which are beyond the Company's control, including natural disasters, power failures, terrorist attacks, equipment or software failures or cyber security attacks. We have initiatives in place to prevent disruptions and disaster recovery plans, and we continue to invest in improvements to these initiatives and plans; however, these measures may not be adequate to prevent or mitigate disruptions. Substantial or repeated systems failures or disruptions, including failures or disruptions related to the Company's complex integration of systems, could reduce the attractiveness of the Company's services versus those of its competitors, materially impair its ability to market its services and operate its flights, result in the unauthorized release of confidential or otherwise protected information, result in increased costs, lost revenue and the loss or compromise of important data, and may adversely affect the Company's business, operating results and financial condition. The Company's business relies extensively on third-party service providers, including certain technology providers. Failure of these parties to perform as expected, or interruptions in the Company's relationships with these providers or their provision of services to the Company, could have a material adverse effect on the Company's business, operating results and financial condition. The Company has engaged third-party service providers to perform a large number of functions that are integral to its business, including regional operations, operation of customer service call centers, distribution and sale of airline seat inventory, provision of information technology infrastructure and services, transmitting or uploading of data, provision of aircraft maintenance and repairs, provision of various utilities, performance of aircraft fueling operations and catering services, among other vital functions and services. The Company does not directly control these third-party service providers, although generally it does enter into agreements that define expected service performance and compliance requirements, such as compliance with legal requirements, including anti-corruption laws; however, there can be no assurance that our third-party service providers will adhere to these requirements. Any of these third-party service providers, however, may materially fail to meet its service performance commitments to the Company or may suffer disruptions to its systems that could impact its services. For example, failures in certain third-party technology or communications systems may cause flight delays or cancellations. The failure of any of the Company's third-party service providers to perform its service obligations adequately, or other interruptions of services, may reduce the Company's revenues and increase its expenses, prevent the Company from operating its flights and providing other services to its customers or result in adverse publicity or harm to our brand. We may also be subject to consequences from any illegal conduct of our third-party service providers, including for their failure to comply with anti-corruption laws, such as the U.S. Foreign Corrupt Practices Act. In addition, the Company's business and financial performance could be materially harmed if its customers believe that its services are unreliable or unsatisfactory. The Company may also have disagreements with such providers or such contracts may be terminated or may not be extended or renewed. For example, the number of flight reservations booked through third-party GDSs or online travel agents ("OTAs") may be adversely affected by disruptions in the business relationships between the Company and these suppliers. Such disruptions, including a failure to agree upon acceptable contract terms when contracts expire or otherwise become subject to renegotiation, may cause the Company's flight information to be limited or unavailable for display by the affected GDS or OTA operator, significantly increase fees for both the Company and GDS/OTA users and impair the Company's relationships with its customers and travel agencies. Any such disruptions or contract terminations may adversely impact our operations and financial results. If we are not able to negotiate or renew agreements with third-party service providers, or if we renew existing agreements on less favorable terms, our operations and financial results may be adversely affected. The Company could experience adverse publicity, harm to its brand, reduced travel demand and potential tort liability as a result of an accident, catastrophe or incident involving its aircraft or its operations, the aircraft or operations of its regional carriers, the aircraft or operations of its codeshare partners, or the aircraft or operations of another airline, which may result in a material adverse effect on the Company's business, operating results and financial condition. An accident, catastrophe or incident involving an aircraft that the Company operates, or an aircraft that is operated by a codeshare partner, one of the Company's regional carriers or another airline, or an incident involving the Company's operations, or the operations of a codeshare partner, one of the Company's regional carriers or of another airline, could have a material adverse effect on the Company if such accident, catastrophe or incident created a public perception that the Company's operations, or the operations of its codeshare partners or regional carriers, are not safe or reliable, or are less safe or reliable than other airlines. Additionally, any accident, catastrophe or incident involving an aircraft type that is operated by the Company, its codeshare partners or regional carriers could have a material adverse effect on the Company if such accident, catastrophe or incident creates a public perception that such aircraft type was not safe or reliable. Such public perception could, in turn, result in adverse publicity for the Company, cause harm to the Company's brand and reduce travel demand on the Company's flights, or the flights of its codeshare partners or regional carriers. In addition, any such accident, catastrophe or incident involving the Company, its regional carriers or its codeshare partners could expose the Company to significant tort liability. Although the Company currently maintains liability insurance in amounts and of the type the Company believes to be consistent with industry practice to cover damages arising from any such accident, catastrophe or incident, and the Company's codeshare partners and regional carriers carry similar insurance and generally indemnify the Company for their operations, if the Company's liability exceeds the applicable policy limits or the ability of another carrier to indemnify it, the Company could incur substantial losses from an accident, catastrophe or incident which may result in a material adverse effect on the Company's operating results and financial condition. Terrorist attacks, international hostilities or other security events, or the fear of terrorist attacks or hostilities, even if not made directly on the airline industry, could negatively affect the Company and the airline industry. Terrorist attacks or international hostilities, even if not made on or targeted directly at the airline industry, or the fear of or the precautions taken in anticipation of such attacks (including elevated national threat warnings, travel restrictions, selective cancellation or redirection of flights and new security regulations) could materially and adversely affect the Company and the airline industry. Security events pose a significant risk to our passenger and cargo operations. These events could include acts of violence in public areas that we cannot control. The Company's financial resources may not be sufficient to absorb the adverse effects of any future terrorist attacks, international hostilities or other security events. Any such events could have a material adverse impact on the Company's financial condition, liquidity and operating results. Increasing privacy and data security obligations or a significant data breach may adversely affect the Company's business. In our regular business operations, we collect, transmit, process and store sensitive data, including personal information of our customers and employees such as payment processing information and information of our business partners. The Company depends on the ability to use information we collect to provide our services and operate our business. The Company must manage increasing legislative, regulatory and consumer focus on privacy issues and data security. For example, in May 2018, the EU's General Data Protection Regulation became effective, which imposes significant privacy and data security requirements, as well as potential for substantial penalties for non-compliance. Recent penalties imposed by regulators have resulted in substantial adverse financial consequences to those companies. Also, some of the Company's commercial partners, such as credit card companies, have imposed data security standards that the Company must meet. These standards continue to evolve. The Company will continue its efforts to meet its privacy and data security obligations; however, it is possible that certain new obligations or customer expectations may be difficult to meet and could increase the Company's costs. Additionally, the Company must manage evolving cybersecurity risks. Our network systems and storage applications, and those systems and storage and other business applications maintained by our third-party providers, may be subject to attempts to gain unauthorized access, breach, malfeasance or other system disruptions. In some cases, it is difficult to anticipate or to detect immediately such incidents and the damage caused thereby. In addition, as attacks by cybercriminals become more sophisticated, frequent and intense, the costs of proactive defense measures may increase. While we continually work to safeguard our internal network systems, including through risk assessments, system monitoring, information security policies and employee awareness and training, and review and validate our third-party security standards, there is no assurance that such actions will be sufficient to prevent cyber-attacks or data breaches. The loss, disclosure, misappropriation of or access to customers', employees' or business partners' information or the Company's failure to meet its obligations could result in legal claims or proceedings, penalties and remediation costs. A significant data breach or the Company's failure to meet its obligations may adversely affect the Company's reputation, relationships with our business partners, business, operating results and financial condition. The mandatory grounding of our Boeing 737 MAX 9 aircraft may have a material adverse effect on our business, operating results and financial condition. On March 13, 2019, the Federal Aviation Administration issued an emergency order prohibiting the operation of Boeing 737 MAX series aircraft by U.S. certificated operators (the "FAA Order"). As a result, the Company grounded all 14 Boeing 737 MAX 9 aircraft in its fleet and Boeing also suspended deliveries of new Boeing 737 MAX series aircraft. The Company does not know whether, on what conditions or when the MAX grounding will end. The long-term operational and financial impact of this grounding is uncertain and could negatively affect the Company based on a number of factors, including, among others, the period of time the aircraft are unavailable, the availability of replacement aircraft, to the extent needed, and the circumstances of any reintroduction of the grounded aircraft to service. In 2019, the grounding affected the delivery of 16 Boeing 737 MAX aircraft that were scheduled for delivery and were not delivered, and it is also expected to affect the timing of future Boeing 737 MAX aircraft deliveries, including the 28 Boeing 737 MAX aircraft that the Company planned to take delivery in 2020. The extent of the delay of future deliveries is expected to be impacted by the length of time the FAA Order remains in place, Boeing's production rate and the pace at which Boeing can deliver aircraft following the lifting of the FAA Order, among other factors. The Company continues to make adjustments to its flight schedule and operations, including substituting replacement aircraft on routes originally intended to be flown by Boeing 737 MAX aircraft. The grounding has impacted the Company's ability to implement its strategic growth strategy, reducing the Company's scheduled capacity from its planned capacity, and has resulted in increased costs as well as lower operating revenue. The Company has had discussions with Boeing regarding compensation from Boeing for the Company's financial damages related to the grounding of the airline's Boeing 737 MAX aircraft; however, the parties have not agreed to any settlement, and the amount, nature and timing of any settlement with Boeing remains uncertain. Disruptions to our regional network and United Express flights provided by third-party regional carriers could adversely affect our business, operating results and financial condition. The Company has contractual relationships with various regional carriers to provide regional aircraft service branded as United Express. These regional operations are an extension of the Company's mainline network and complement the Company's operations by carrying traffic that connects to mainline service and allows flights to smaller cities that cannot be provided economically with mainline aircraft. The Company's business and operations are dependent on its regional flight network, with regional capacity accounting for approximately 11% of the Company's total capacity for the year ended December 31, 2019. Although the Company has agreements with its regional carriers that include contractually agreed performance metrics, each regional carrier is a separately certificated commercial air carrier and the Company does not control the operations of these carriers. A number of factors may impact the Company's regional network, including weather-related effects and seasonality. In addition, the decrease in qualified pilots driven by changes to federal regulations has adversely impacted and could continue to affect the Company's regional flying. For example, the FAA's expansion of minimum pilot qualification standards, including a requirement that a pilot have at least 1,500 total flight hours, as well as the FAA's revised pilot flight and duty time requirements under Part 117 of the Federal Aviation Regulations, have contributed to a smaller supply of pilots available to regional carriers. The decrease in qualified pilots resulting from the regulations as well as factors including a decreased student pilot population and a shrinking U.S. military from which to hire qualified pilots, could adversely impact the Company's operations and financial condition, and could also require the Company to reduce regional carrier flying. If a significant disruption occurs to the Company's regional network or flights or if one or more of the regional carriers with which the Company has relationships is unable to perform their obligations over an extended period of time, there could be a material adverse effect on the Company's business, operating results and financial condition. Current or future litigation and regulatory actions, or failure to comply with the terms of any settlement, order or arrangement relating to these actions, could have a material adverse impact on the Company. From time to time, we are subject to litigation and other legal and regulatory proceedings relating to our business or investigations or other actions by governmental agencies, including as described in Part I, Item 3, Legal Proceedings, of this report. No assurances can be given that the results of these or new matters will be favorable to us. An adverse resolution of lawsuits, arbitrations, investigations or other proceedings or actions could have a material adverse effect on our financial condition and operating results, including as a result of non-monetary remedies, and could also result in adverse publicity. Defending ourselves in these matters may be time-consuming, expensive and disruptive to normal business operations and may result in significant expense and a diversion of management's time and attention from the operation of our business, which could impede our ability to achieve our business objectives. Additionally, any amount that we may be required to pay to satisfy a judgment, settlement, fine or penalty may not be covered by insurance. If we fail to comply with the terms contained in any settlement, order or agreement with a governmental authority relating to these matters, we could be subject to criminal or civil penalties, which could have a material adverse impact on the Company. Under our charter and certain indemnification agreements that we have entered into (and may in the future enter into) with our officers, directors and certain third parties, we could be required to indemnify and advance expenses to them in connection with their involvement in certain actions, suits, investigations and other proceedings. There can be no assurance that any of these payments will not be material. Our significant investments in other airlines, including in other parts of the world, and the commercial relationships that we have with those carriers may not produce the returns or results we expect. An important part of our strategy to expand our global network includes making significant investments in airlines both domestically and in other parts of the world and expanding our commercial relationships with these carriers. For example, in January 2019, we completed the acquisition of a 49.9% interest in ManaAir LLC, which, as of immediately following the closing of that investment, owns 100% of the equity interests in ExpressJet Airlines LLC, a domestic regional airline. We also have minority equity interests in CommutAir and Republic Airways Holdings Inc. See Note 9 to the financial statements included in Part II, Item 8 of this report for additional information regarding our investments in regional airlines. We also have significant investments in Latin American airlines, including significant investments in Avianca Holdings, S.A. ("AVH") and BRW Aviation LLC ("BRW"), an affiliate of Synergy Aerospace Corporation and the majority shareholder of AVH, and an equity investment in Azul. See Note 8 and Note 9 to the financial statements included in Part II, Item 8 of this report for additional information regarding our investments in AVH and Azul, respectively. See also the additional risks with respect to our investment in AVH described in this Part I, Item 1A. Risk Factors. We expect to continue exploring similar non-controlling investments in, and entering into JBAs, commercial agreements, loan transactions and strategic alliances with, other carriers as part of our regional and global business strategy. These transactions and relationships involve significant challenges and risks, and we face competition in forming and maintaining these relationships, since there are a limited number of potential arrangements and other airlines are looking to enter into similar relationships. We are dependent on these other carriers for significant aspects of our network in the regions in which they operate. While we work closely with these carriers, each is a separately certificated commercial air carrier, and we do not have control over their operations, strategy, management or business methods. And not only are these airlines subject to a number of the same risks as our business, which are described elsewhere in this Part I, Item 1A. Risk Factors, including competitive pressures on pricing, demand and capacity, changes in aircraft fuel pricing, and the impact of global and local political and economic conditions on operations and customer travel patterns, among others, they are also subject to their own distinct financial and operational risks. As a result of these and other factors, we may not realize a satisfactory return on our investment, and we may not receive repayment of any invested or loaned funds. Further, these investments may not generate the revenue or operational synergies we expect, and they may distract management focus from our operations or other strategic options. Finally, our reliance on these other carriers in the regions in which they operate may negatively impact our regional and global operations and results if those carriers are impacted by general business risks or perform below our expectations or needs. Any one or more of these events could have a material adverse effect on our operating results or financial condition. We may also be subject to consequences from any illegal conduct of JBA partners, including for failure to comply with anti-corruption laws such as the U.S. Foreign Corrupt Practices Act. Furthermore, our relationships with these carriers may be subject to the laws and regulations of non-U.S. jurisdictions in which these carriers are located or conduct business. In addition, any political or regulatory change in these jurisdictions that negatively impacts or prohibits our arrangements with these carriers could have an adverse effect on our operating results or financial condition. To the extent that the operations of any of these carriers are disrupted over an extended period of time or their actions subject us to the consequences of failure to comply with laws and regulations, our operating results may be adversely affected. Our significant investments in AVH and its affiliates, and the commercial relationships that we have with Avianca may not produce the returns or results we expect. In November 2018, as part of our global network strategy, United entered into a revenue-sharing JBA with Avianca, a subsidiary of AVH, Copa and several of their respective affiliates, subject to regulatory approval. Concurrently with this transaction, United, as lender, entered into a Term Loan Agreement (the "BRW Term Loan Agreement") with, among others, BRW Aviation Holding LLC ("BRW Holding") and BRW, as guarantor and borrower, respectively. Pursuant to the BRW Term Loan Agreement, United provided to BRW a $456 million term loan (the "BRW Term Loan"), secured by a pledge of BRW's equity, as well as BRW's 516 million common shares of AVH (which are eligible to be converted into the same number of preferred shares, which maybe be deposited with the depositary for AVH's American Depositary Receipts ("ADRs"), the class of AVH securities that trades on the New York Stock Exchange (the "NYSE"), in exchange for 64.5 million ADRs) (such shares and equity, collectively, the "BRW Loan Collateral"). BRW is currently in default under the BRW Term Loan Agreement. In order to protect the value of its collateral, on May 24, 2019, United began to exercise certain remedies available to it under the terms of the BRW Term Loan Agreement and related documents. In connection with the delivery by United of a notice of default to BRW, Kingsland Holdings Limited ("Kingsland"), AVH's largest minority shareholder, was granted, in accordance with the agreements related to the BRW Term Loan Agreement, authority to manage BRW, which remains the majority shareholder of AVH. After a hearing on September 26, 2019, a New York state court granted Kingsland summary judgment authorizing it to foreclose on the BRW Loan Collateral under the BRW Term Loan Agreement. Kingsland is continuing with the foreclosure process, which is expected to result in a judicially supervised sale of the BRW Loan Collateral. The New York state court also granted Kingsland's motion for a preliminary injunction that, among other things, enjoins BRW Holding from interfering with Kingsland's ability to exercise voting and other rights in certain equity interests in BRW. These rulings are intermediate steps in the judicial foreclosure process in New York and are subject to appeal. The repayment of the BRW Term Loan is dependent on this judicial foreclosure process and there is no assurance that a judicial foreclosure sale will be completed, or, if completed, will result in the full satisfaction of all of the obligations under the BRW Term Loan. Our ability to enforce a deficiency judgment against BRW in the event that the proceeds from the sale of the BRW Loan Collateral in the judicial foreclosure are insufficient to repay the full amount of the BRW Term Loan may be limited. Any of these circumstances may lead to a loss or delay in the repayment of the BRW Term Loan. Further, the amount we receive from the foreclosure sale of the BRW Loan Collateral may be inadequate to fully pay the amounts owed to us by BRW and our costs incurred to foreclose, repossess and sell the property. In November 2019, United entered into a senior secured convertible term loan agreement (the "AVH Convertible Loan Agreement") with, among others, AVH, as borrower, for the provision by the lenders thereunder (including United) to AVH of convertible term loans for general corporate purposes. In December 2019, United provided such a convertible term loan to AVH under the Convertible Loan Agreement in the aggregate amount of $150 million (the "AVH Convertible Loan"). See Note 8 to the financial statements included in Part II, Item 8 of this report for additional information regarding our investments in AVH and its affiliates. These transactions and relationships involve significant challenges and risks, particularly given AVH's recent debt restructuring and the judicial foreclosure process to which the repayment of the BRW Term Loan is subject. While AVH has successfully carried out its debt restructuring plan to date, there is no guarantee that such debt restructuring plan will improve AVH's long-term financial condition, United's exposure to which has increased with the completion of the AVH Convertible Loan. While we work closely with Avianca in connection with the JBA, and have supported AVH by providing capital in the form of the AVH Convertible Loan, Avianca is a separately certificated commercial air carrier, and we do not have control over its or AVH's operations, strategy, management or business methods. Avianca is also subject to a number of the same risks as our business, which are described in this Part I, Item 1A, Risk Factors, including competitive pressures on pricing, demand and capacity, changes in aircraft fuel pricing, and the impact of global and local political and economic conditions on operations and customer travel patterns, among others, as well as to its own distinct financial and operational risks. In addition, the value of the BRW Loan Collateral and the collateral securing the AVH Convertible Loan is subject to market and other conditions. Changes in the aviation market may adversely affect the value of the BRW Loan Collateral and the collateral securing the AVH Convertible Loan and thereby lower the value to be derived from a foreclosure or other exercise of remedies with respect to the BRW Term Loan Agreement or the AVH Convertible Loan. As a result of these and other factors, including delays in foreclosure proceedings, we may not receive full repayment of our BRW Term Loan or our AVH Convertible Loan, and we may be unable to realize the full value of the BRW Loan Collateral or the collateral securing the AVH Convertible Loan. As a consequence, we may not realize a satisfactory return on our invested or loaned funds with respect to AVH and its affiliates. Further, these investments may not generate the revenue or operational synergies we expect, and they may distract management focus from our operations or other strategic options. Finally, our reliance on Avianca in the region in which it operates may negatively impact our global operations and results if AVH does not successfully recover from its debt restructuring or is otherwise impacted by general business risks or performs below our expectations or needs. Any one or more of these events could have a material adverse effect on our operating results or financial condition. The airline industry may undergo further change with respect to alliances and JBAs or due to consolidations, any of which could have a material adverse effect on the Company. The Company faces, and may continue to face, strong competition from other carriers due to the modification of alliances and formation of new JBAs. Carriers may improve their competitive positions through airline alliances, slot swaps and/or JBAs. Certain types of airline JBAs further competition by allowing multiple airlines to coordinate routes, pool revenues and costs, and enjoy other mutual benefits, achieving many of the benefits of consolidation. Open Skies agreements, including the longstanding agreements between the United States and each of the EU, Canada, Japan, Korea, New Zealand, Australia, Colombia and Panama, as well as the more recent agreements between the United States and each of Mexico and Brazil, may also give rise to better integration opportunities among international carriers. Movement of airlines between current global airline alliances could reduce joint network coverage for members of such alliances while also creating opportunities for JBAs and bilateral alliances that did not exist before such realignment. Further airline and airline alliance consolidations or reorganizations could occur in the future. The Company routinely engages in analyses and discussions regarding its own strategic position, including current and potential alliances, asset acquisitions and divestitures and may have future discussions with other airlines regarding strategic activities. If other airlines participate in such activities, those airlines may significantly improve their cost structures or revenue generation capabilities, thereby potentially making them stronger competitors of the Company and potentially impairing the Company's ability to realize expected benefits from its own strategic relationships. Orders for new aircraft typically must be placed years in advance of scheduled deliveries, and changes in the Company's network strategy over time or other factors outside of the Company's control may make aircraft on order less economic for the Company, result in costs related to modification or termination of aircraft orders or cause the Company to enter into orders for new aircraft on less favorable terms. The Company's orders for new aircraft are typically made years in advance of actual delivery of such aircraft, and the financial commitment required for purchases of new aircraft is substantial. At December 31, 2019, the Company had firm commitments to purchase 304 new aircraft from The Boeing Company ("Boeing"), Airbus S.A.S ("Airbus") and Embraer S.A. ("Embraer"), as well as related agreements with engine manufacturers, maintenance providers and others. As of December 31, 2019, the Company's commitments relating to the acquisition of aircraft and related spare engines, aircraft improvements and other related obligations aggregated to a total of $26.7 billion. Subsequent to the Company placing an order for new aircraft, the Company's network strategy may change. As a result, the Company's preference for a particular aircraft that it has ordered, often years in advance, may be decreased or eliminated. If the Company were to modify or terminate any of its existing aircraft order commitments, it may be responsible for material liabilities to its counterparties arising from any such modification. Additionally, the Company may have a need for additional aircraft that are not available under its existing orders. In such cases, the Company may seek to acquire aircraft from other sources, such as through lease arrangements, which may result in higher costs or less favorable terms, or through the purchase or lease of used aircraft. The Company may not be able to acquire such aircraft when needed on favorable terms or at all. The imposition of new tariffs, or any increase in existing tariffs, on the importation of commercial aircraft that the Company orders may result in higher costs. For example, in October 2019, the United States imposed tariffs on certain imports from the EU, including a customs duty at an ad valorem rate of 10% on new commercial aircraft, which rate, in February 2020, was increased to 15%. These tariffs apply to certain new Airbus aircraft that we have on order. While the scope and rate of these tariffs are subject to change, if and to the extent these tariffs are imposed on us, they could increase the effective cost of, among other things, new Airbus aircraft. A majority of the Company's aircraft and certain parts are sourced from single suppliers; therefore, the Company would be materially and adversely affected if it were unable to obtain timely deliveries, additional equipment or support from any of these suppliers. The Company currently sources the majority of its aircraft and many related aircraft parts from Boeing. In addition, our aircraft suppliers are dependent on other suppliers for certain other aircraft parts. Therefore, if the Company is unable to acquire additional aircraft from Boeing, or if Boeing fails to make timely deliveries of aircraft or to provide adequate support for its products, the Company's operations could be materially and adversely affected. The Company is also dependent on a limited number of suppliers for aircraft engines and certain other aircraft parts and could, therefore, also be materially and adversely affected in the event of the unavailability of these engines and other parts. Union disputes, employee strikes or slowdowns, and other labor-related disruptions could adversely affect the Company's operations and could result in increased costs that impair its financial performance. United is a highly unionized company. As of December 31, 2019, the Company and its subsidiaries had approximately 96,000 active employees, of whom approximately 84% were represented by various U.S. labor organizations. See Part I, Item 1. Business-Employees, of this report for additional information on our represented employee groups and collective bargaining agreements. There is a risk that unions or individual employees might pursue judicial or arbitral claims arising out of changes implemented as a result of the Company entering into collective bargaining agreements with its represented employee groups. There is also a possibility that employees or unions could engage in job actions such as slowdowns, work-to-rule campaigns, sick-outs or other actions designed to disrupt the Company's normal operations, in an attempt to pressure the Company in collective bargaining negotiations. Although the RLA makes such actions unlawful until the parties have been lawfully released to self-help, and the Company can seek injunctive relief against premature self-help, such actions can cause significant harm even if ultimately enjoined. Similarly, if the operations of our third-party regional carriers, ground handlers or other vendors are impacted by labor-related disruptions, our operations could be adversely affected. In addition, collective bargaining agreements with the Company's represented employee groups increase the Company's labor costs, which increase could be material. An outbreak of disease or similar public health threat, such as the coronavirus, could have a material adverse impact on the Company's business, operating results and financial condition. An outbreak of disease or similar public health threat, or fear of such an event, that affects travel demand, travel behavior, or travel restrictions could have a material adverse impact on the Company's business, financial condition and operating results. In addition, outbreaks of disease could result in increased government restrictions and regulation, including quarantines of our personnel or an inability to access facilities or our aircraft, which could adversely affect our operations. In December 2019, a novel strain of coronavirus ("COVID-19") was reported in Wuhan, China. The World Health Organization has declared COVID-19 to constitute a "Public Health Emergency of International Concern." On January 30, 2020, the U.S. Department of State issued a Level 4 "do not travel" advisory for China. The U.S. government has also implemented enhanced screenings, quarantine requirements and travel restrictions in connection with the COVID-19 outbreak. The Company has suspended its flights between the United States and each of Beijing, Chengdu, Shanghai and Hong Kong through April 24, 2020. These routes represented approximately 5% of the Company's 2020 planned capacity and the Company's other trans-Pacific routes represented an additional 10% of the Company's 2020 planned capacity. As of the date of this report, the Company is experiencing an approximately 100% decline in near-term demand to China and an approximately 75% decline in near-term demand on the rest of the Company's trans-Pacific routes. The extent of the impact of the COVID-19 on the Company's operational and financial performance will depend on future developments, including the duration and spread of the outbreak and related travel advisories and restrictions and the impact of the COVID-19 on overall demand for air travel, all of which are highly uncertain and cannot be predicted. If traffic on the Company's trans-Pacific routes were to remain at these levels for an extended period, and/or routes in other parts of the Company's network begin to see significant declines in demand, our results of operations for full year 2020 may be materially adversely affected. If we experience changes in, or are unable to retain, our senior management team or other key employees, our operating results could be adversely affected. Much of our future success depends on the continued availability of skilled personnel with industry experience and knowledge, including our senior management team and other key employees. If we are unable to attract and retain talented, highly qualified senior management and other key employees, or if we are unable to effectively provide for the succession of senior management, our business may be adversely affected. Extended interruptions or disruptions in service at major airports where we operate could have a material adverse impact on our operations. The airline industry is heavily dependent on business models that concentrate operations in major airports in the United States and throughout the world. An extended interruption or disruption at an airport where we have significant operations could have a material impact on our business, financial condition and results of operation. We operate principally through our domestic hubs in at Newark, Chicago O'Hare, Denver, Houston Bush, LAX, Guam, SFO and Washington Dulles. Substantially all of our flights either originate in or fly into one of these locations. A significant interruption or disruption in service at one of our hubs or other airports where we have a significant presence resulting from ATC delays, weather conditions, natural disasters, growth constraints, relations with third-party service providers, failure of computer systems, disruptions to government agencies or personnel (including as a result of government shutdowns), disruptions at airport facilities or other key facilities used by us to manage our operations, labor relations, power supplies, fuel supplies, terrorist activities, international hostilities or otherwise could result in the cancellation or delay of a significant portion of our flights and, as a result, could have a material impact on our business, operating results and financial condition. We have minimal control over the operation, quality or maintenance of these services or whether vendors will improve or continue to provide services that are essential to our business. The airline industry is subject to extensive government regulation, which imposes significant costs and may adversely impact our business, operating results and financial condition. Airlines are subject to extensive regulatory and legal oversight. Compliance with U.S. and international regulations imposes significant costs and may have adverse effects on the Company. Laws, regulations, taxes and airport rates and charges, both domestically and internationally, have been proposed from time to time that could significantly increase the cost of airline operations or reduce airline revenue. The airline industry is heavily taxed and additional taxation could negatively impact our business. United provides air transportation under certificates of public convenience and necessity issued by the DOT. If the DOT altered, amended, modified, suspended or revoked these certificates, it could have a material adverse effect on the Company's business. The DOT also regulates consumer protection and, through its investigations or rulemaking authority, could impose restrictions that materially impact the Company's business. The FAA regulates the safety of United's operations. United operates pursuant to an air carrier operating certificate issued by the FAA. The FAA's regulations include stringent pilot flight and duty time requirements under Part 117 of the Federal Aviation Regulations, as well as minimum qualifications for air carrier first officers. These regulations have caused mainline airlines to hire regional pilots, while simultaneously significantly reducing the pool of new pilots from which regional carriers themselves can hire. Although this is an industry issue, it directly affects the Company and has required it to reduce regional partner flying, as several regional partners have experienced difficulty flying their schedules due to reduced pilot availability. From time to time, the FAA also issues orders, airworthiness directives and other regulations relating to the maintenance and operation of aircraft that require material expenditures or operational restrictions by the Company. These FAA orders and directives have resulted in the temporary grounding of an entire aircraft type if the FAA identifies design, manufacturing, maintenance or other issues requiring immediate corrective action (including the FAA Order grounding Boeing 737 MAX aircraft). These FAA directives or requirements could have a material adverse effect on the Company. In 2018, the U.S. Congress approved a five-year reauthorization for the FAA, which encompasses significant aviation tax and policy-related issues. The law includes a range of policy changes related to airline customer service and aviation safety which are ongoing and, depending on how they are implemented, could impact our operations and costs. Additionally, the U.S. Congress may consider legislation related to aviation safety as well as environmental issues which could impact the Company and the airline industry. The Company's operations may also be adversely impacted due to the existing antiquated ATC system utilized by the U.S. government and regulated by the FAA. During peak travel periods in certain markets, the current ATC system's inability to handle demand has led to short-term capacity constraints imposed by government agencies and resulted in delays and disruptions of air traffic. In addition, the current system will not be able to effectively handle projected future air traffic growth. The outdated technologies also cause the ATC to be less resilient in the event of a failure, causing flight cancellations and delays. Imposition of these ATC constraints on a long-term basis may have a material adverse effect on the Company's operations. Failure to update the ATC system in a timely manner and the substantial funding requirements of a modernized ATC system that may be imposed on air carriers may have an adverse impact on the Company's financial condition or operating results. Access to landing and take-off rights, or "slots," at several major U.S. airports and many foreign airports served by the Company are, or recently have been, subject to government regulation. Certain of the Company's major hubs are among the most congested airports in the United States and have been or could be the subject of regulatory action that might limit the number of flights and/or increase costs of operations at certain times or throughout the day. The FAA may limit the Company's airport access by limiting the number of departure and arrival slots at high density traffic airports, which could affect the Company's ownership and transfer rights, and local airport authorities may have the ability to control access to certain facilities or the cost of access to their facilities, which could have an adverse effect on the Company's business. The FAA historically has taken actions with respect to airlines' slot holdings that airlines have challenged; if the FAA were to take actions that adversely affect the Company's slot holdings, the Company could incur substantial costs to preserve its slots or may lose slots. If slots are eliminated at an airport, or if the number of hours of operation governed by slots is reduced at an airport, the lack of controls on take-offs and landings could result in greater congestion both at the affected airport or in the regional airspace (e.g., the New York City metropolitan region airspace) and could significantly impact the Company's operations. Further, the Company's operating costs at airports, including the Company's major hubs, may increase significantly because of capital improvements at such airports that the Company may be required to fund, directly or indirectly. Such costs could be imposed by the relevant airport authority without the Company's approval and may have a material adverse effect on the Company's financial condition. The ability of carriers to operate flights on international routes between the United States and other countries is highly regulated. Applicable arrangements between the United States and foreign governments may be amended from time to time, government policies with respect to airport operations may be revised, and the availability of appropriate slots or facilities may change. The Company currently operates a number of flights on international routes under government arrangements, regulations or policies that designate the number of carriers permitted to operate on such routes, the capacity of the carriers providing services on such routes, the airports at which carriers may operate international flights, or the number of carriers allowed access to particular airports. Any limitations, additions or modifications to such arrangements, regulations or policies could have a material adverse effect on the Company's financial condition and operating results. Additionally, a change in law, regulation or policy for any of the Company's international routes, such as Open Skies, could have a material adverse impact on the Company's financial condition and operating results and could result in the impairment of material amounts of related tangible and intangible assets. In addition, competition from revenue-sharing JBAs and other alliance arrangements by and among other airlines could impair the value of the Company's business and assets on the Open Skies routes. The Company's plans to enter into or expand U.S. antitrust immunized alliances and JBAs on various international routes are subject to receipt of approvals from applicable U.S. federal authorities and obtaining other applicable foreign government clearances or satisfying the necessary applicable regulatory requirements. There can be no assurance that such approvals and clearances will be granted or will continue in effect upon further regulatory review or that changes in regulatory requirements or standards can be satisfied. See Part I, Item 1. Business-Industry Regulation, of this report for additional information on government regulation impacting the Company. We are subject to many forms of environmental regulation and liability and risks associated with climate change, and may incur substantial costs as a result. Many aspects of the Company's operations are subject to increasingly stringent federal, state, local and international laws protecting the environment, including those relating to emissions to the air, water discharges, safe drinking water and the use and management of hazardous materials and wastes. Compliance with existing and future environmental laws and regulations can require significant expenditures and violations can lead to significant fines and penalties. In addition, from time to time we are identified as a responsible party for environmental investigation and remediation costs under applicable environmental laws due to the disposal of hazardous substances generated by our operations. We could also be subject to environmental liability claims from various parties, including airport authorities, related to our operations at our owned or leased premises or the off-site disposal of waste generated at our facilities. We may incur substantial costs as a result of changes in weather patterns due to climate change. Increases in the frequency, severity or duration of severe weather events such as thunderstorms, hurricanes, flooding, typhoons, tornados and other severe weather events could result in increases in delays and cancellations, turbulence-related injuries and fuel consumption to avoid such weather, any of which could result in significant loss of revenue and higher costs. To mitigate climate change risks, CORSIA has been developed by ICAO, a UN specialized agency. CORSIA is intended to create a single global market-based measure to achieve carbon-neutral growth for international aviation after 2020 through airline purchases of carbon offset credits. Certain CORSIA program details remain to be developed and could potentially be affected by political developments in participating countries or the results of the pilot phase of the program, and thus the impact of CORSIA cannot be fully predicted. However, CORSIA is expected to result in increased operating costs for airlines that operate internationally, including the Company. In addition to CORSIA, the EPA has begun preliminary work to adopt its own aircraft engine GHG emission standards, which were expected to be aligned with recent ICAO carbon dioxide emission standards. The timing of any U.S. EPA aircraft engine GHG emission standards is currently unknown, but some jurisdictions in which United operates have adopted or are considering GHG emission reduction initiatives, which could impact various aspects of the Company's business. The precise nature of future requirements and their applicability to the Company are difficult to predict, but the financial impact to the Company and the aviation industry would likely be adverse and could be significant. See Part I, Item 1. Business-Industry Regulation-Environmental Regulation, of this report for additional information on environmental regulation impacting the Company. The United Kingdom's withdrawal from the EU may adversely impact our operations in the United Kingdom and elsewhere. In June 2016, United Kingdom ("UK") voters approved an advisory referendum for the UK to exit the EU. The UK parliament voted in favor of allowing the government to commence negotiations to determine the future terms of the UK's relationship with the EU, including the terms of trade between the UK and the EU and other nations. On January 31, 2020, the UK withdrew from the EU, and started a transition period that will potentially run through December 31, 2020. The nature and terms of the UK's relationship with the EU after the transition period remain uncertain. In connection with a UK exit from the EU, we could face new challenges in our operations, such as instability in global financial and foreign exchange markets. This instability could result in market volatility, including in the value of the British pound and European euro, additional travel restrictions on passengers traveling between the UK and other EU countries, changes to the legal status of EU-resident employees, legal uncertainty and divergent national laws and regulations. At this time, we cannot predict the impact that the UK's exit from the EU will have on our business generally and our UK and European operations more specifically, and no assurance can be given that our operating results, financial condition and prospects would not be adversely impacted by the result. The Company's operating results fluctuate due to seasonality and other factors associated with the airline industry, many of which are beyond the Company's control. Due to greater demand for air travel during the spring and summer months, revenues in the airline industry in the second and third quarters of the year are generally stronger than revenues in the first and fourth quarters of the year, which are periods of lower travel demand. The Company's operating results generally reflect this seasonality, but have also been impacted by numerous other factors that are not necessarily seasonal, including, among others, extreme or severe weather, outbreaks of disease or pandemics, ATC congestion, geological events, political instability, terrorism, natural disasters, changes in the competitive environment due to industry consolidation, tax obligations, general economic conditions and other factors. As a result, the Company's quarterly operating results are not necessarily indicative of operating results for an entire year and historical operating results in a quarterly or annual period are not necessarily indicative of future operating results. Increases in insurance costs or inadequate insurance coverage may materially and adversely impact our business, operating results and financial condition. The Company could be exposed to significant liability or loss if its property or operations were to be affected by a natural catastrophe or other event, including aircraft accidents. The Company maintains insurance policies, including, but not limited to, terrorism, aviation hull and liability, workers' compensation and property and business interruption insurance, but we are not fully insured against all potential hazards and risks incident to our business. If the Company is unable to obtain sufficient insurance with acceptable terms, the costs of such insurance increase materially, or if the coverage obtained is insufficient relative to actual liability or losses that the Company experiences, whether due to insurance market conditions, policy limitations and exclusions or otherwise, our operating results and financial condition could be materially and adversely affected. The Company has a significant amount of financial leverage from fixed obligations, and insufficient liquidity may have a material adverse effect on the Company's financial condition and business. The Company has a significant amount of financial leverage from fixed obligations, including aircraft lease and debt financings, leases of airport property and other facilities, and other material cash obligations. In addition, the Company has substantial noncancelable commitments for capital expenditures, including for the acquisition of new aircraft and related spare engines. Although the Company's cash flows from operations and its available capital, including the proceeds from financing transactions, have been sufficient to meet these obligations and commitments to date, the Company's future liquidity could be negatively affected by the risk factors discussed in this report. If the Company's liquidity is materially diminished, the Company might not be able to timely pay its leases and debts or comply with certain operating and financial covenants under its financing and credit card processing agreements or with other material provisions of its contractual obligations. The Company's substantial level of indebtedness and non-investment grade credit rating, as well as market conditions and the availability of assets as collateral for loans or other indebtedness, may make it difficult for the Company to raise additional capital if needed to meet its liquidity needs on acceptable terms, or at all. In addition, as of December 31, 2019, the Company had $3.4 billion in variable rate indebtedness, all or a portion of which uses London interbank offered rates ("LIBOR") as a benchmark for establishing applicable rates. As announced in July 2017, LIBOR is expected to be phased out by the end of 2021. Although many of our LIBOR-based obligations provide for alternative methods of calculating the interest rate payable if LIBOR is not reported, the extent and manner of any future changes with respect to methods of calculating LIBOR or replacing LIBOR with another benchmark are unknown and impossible to predict at this time and, as such, may result in interest rates that are materially higher than current interest rates. If interest rates applicable to the Company's variable interest indebtedness increase, the Company's interest expense will also increase, which could make it difficult for the Company to make interest payments and fund other fixed costs and, in turn, adversely impact our cash flow available for general corporate purposes. See Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations, of this report for additional information regarding the Company's liquidity. Agreements governing our debt include financial and other covenants. Failure to comply with these covenants could result in events of default. Our financing agreements include various financial and other covenants. Certain of these covenants require UAL or United, as applicable, to maintain minimum liquidity and/or minimum collateral coverage ratios. UAL's or United's ability to comply with these covenants may be affected by events beyond its control, including the overall industry revenue environment, the level of fuel costs and the appraised value of the collateral. In addition, our financing agreements contain other negative covenants customary for such financings. These covenants are subject to important exceptions and qualifications. If we fail to comply with these covenants and are unable to remedy or obtain a waiver or amendment, an event of default would result. If an event of default were to occur, the lenders could, among other things, declare outstanding amounts immediately due and payable. In addition, an event of default or declaration of acceleration under one financing agreement could also result in an event of default under other of our financing agreements due to cross-default and cross-acceleration provisions. The acceleration of significant amounts of debt could require us to renegotiate, repay or refinance the obligations under our financing arrangements. The Company may never realize the full value of its intangible assets or its long-lived assets causing it to record impairments that may negatively affect its financial condition and operating results. In accordance with applicable accounting standards, the Company is required to test its indefinite-lived intangible assets for impairment on an annual basis, or more frequently where there is an indication of impairment. In addition, the Company is required to test certain of its other assets for impairment where there is any indication that an asset may be impaired. The Company may be required to recognize losses in the future due to, among other factors, extreme fuel price volatility, tight credit markets, government regulatory changes, decline in the fair values of certain tangible or intangible assets, such as aircraft, route authorities, airport slots and frequent flyer database, unfavorable trends in historical or forecasted results of operations and cash flows and an uncertain economic environment, as well as other uncertainties. For example, in 2019 and 2018, the Company recorded impairment charges of $90 million and $206 million, respectively, associated with its Hong Kong routes, resulting in the full impairment of these assets. The Company can provide no assurance that a material impairment loss of tangible or intangible assets will not occur in a future period. The value of the Company's aircraft could be impacted in future periods by changes in supply and demand for these aircraft. Such changes in supply and demand for certain aircraft types could result from the grounding of aircraft. An impairment loss could have a material adverse effect on the Company's financial condition and operating results. Any damage to our reputation or brand image could adversely affect our business or financial results. We operate in a public-facing industry and maintaining a good reputation is critical to our business. The Company's reputation or brand image could be adversely impacted by any failure to maintain satisfactory practices for all of our operations and activities, any failure to achieve and/or make progress toward our environmental and sustainability goals, public pressure from investors or policy groups to change our policies, customer perceptions of our advertising campaigns, sponsorship arrangements or marketing programs, customer perceptions of our use of social media, or customer perceptions of statements made by us, our employees and executives, agents or other third parties. Damage to our reputation or brand image or loss of customer confidence in our services could adversely affect our business and financial results, as well as require additional resources to rebuild our reputation. ITEM 1B.
