D I S C O V E R Y C O M M U N I C A T I O N S D I S C O V E R Y C O M M U N I C A T I O N S DEAR SHAREHOLDERS, Discovery launched in 1985 as a single channel with a singular mission: to tell stories that entertain, inspire and ignite curiosity. From that mission grew a purpose-driven company, which — 30 years later — is the leader in global entertainment, reaching 3 billion cumulative viewers around the world with the ﬁ nest brands, programs and storytellers. As we’ve grown, we’ve evolved. At a time when viewing habits are changing rapidly, we’re reaching record audiences in more countries, on more platforms and across more screens than ever before. Still, the heart of Discovery Communications is and always will be our content, powered by stories of the planet that we search out, capture and bring to the world. Compelling, on-brand programming drove Discovery’s growth in 2015. In the U.S., Discovery Channel, Investigation Discovery, Velocity and OWN garnered record viewership, and propelled Discovery’s U.S. portfolio to more than 11% market share. This led to a strong year in distribution and advertising revenue in the U.S. Internationally, our female lifestyle brands drove 10% audience growth. Reaching the 3 billion viewers mark worldwide in 2015 was both a historic milestone and a bright signal that we continue our growth. Our global distribution platform paved the way for Discovery Channel to debut RACING EXTINCTION, a ﬁ lm spotlighting the plight of endangered species, to the network’s global footprint of 500 million homes. While staying focused on satisfying curiosity and entertaining viewers with high-quality content through our global brands, Discovery also focused on diversiﬁ ed genres in 2015, most notably a new European sports strategy with Eurosport and the international expansion of Discovery Kids. In addition to taking full ownership of Eurosport in 2015, Discovery and Eurosport acquired all European TV and multiplatform broadcast rights to the 2018-2024 Olympic Games. This game-changing deal strengthens our position as the leader in sports across the continent. In Latin America, our investment in kids’ content continued to drive growth where, for the sixth year in a row, Discovery Kids was the #1 pay-TV network in Brazil. Our genre expansion positions us to win in a multiplatform world with viewers, distributors and advertisers. Proving the power of our brands, we executed strong renewals with distribution partners around the world in 2015. Among these successes were a favorable renewal with Comcast in the U.S., key deals and new partnerships in Norway, France, Singapore and Poland, and a new multiplatform deal with Verizon's Go90 and Hulu in the U.S. 2 0 1 5 A N N U A L R E P O R T Discovery’s multiplatform strategy produced new off erings this year including the launch of Discovery GO, our ﬁ rst TV Everywhere platform in the U.S.; Discovery Kids Play, the company’s ﬁ rst TV Everywhere off ering in Latin America; free-to-air channels in emerging markets such as Turkey and the Middle East; and the continued growth of the company’s direct-to-consumer business in Europe with Eurosport Player and Dplay. Investing in strong, must-have IP remains an integral part of our future success and our evolution as a company. In 2015, we took a stake in Lionsgate Entertainment which, along with our ownership of production companies All3Media and Raw, will strengthen our global content pipeline. We also launched Discovery VR, our ﬁ rst virtual reality product, which continues our long-standing tradition of leveraging technology to innovate our storytelling. While the world is changing, we are changing with it. Discovery’s unique model — an unmatched global distribution platform; world-class brands; and cost-eff ective IP in popular genres with universal appeal — sets us apart. This advantage propels our ability to create multiplatform connections with viewers, advertisers and affi liates and monetize our content as consumption grows across all screens. Our content compelling and our brands never stronger, Discovery has entered 2016 with real business momentum. Looking ahead, we will drive shareholder value by creating content that attracts new audiences and fulﬁ lls our mission as a purpose-driven company. We remain committed to creating programs that unite, ignite and inspire our viewers … and we will indeed go wherever the story takes us. David M. Zaslav Robert J.

Our strategyis to maximize the distribution, ratings and profit potential of each of our branded networks. In addition to growing distribution and advertising revenues forour branded networks, we are extending content distribution across new platforms, including brand-aligned websites, web-native networks, on-line streaming,mobile devices, video on demand (“VOD”) and broadband channels, which provide promotional platforms for our television content and serve as additionaloutlets for advertising and distribution revenue. Audience ratings are a key driver in generating advertising revenue and creating demand on the part of cabletelevision operators, direct-to-home ("DTH") satellite operators, telecommunication service providers, and other content distributors who deliver our contentto their customers.Our content spans genres including survival, exploration, sports, lifestyle, general entertainment, heroes, adventure, crime and investigation, health andkids.

Our U.S. Networks segmentprincipally consists of national television networks. Our U.S. Networks segment owns and operates ten national television networks, including fullydistributed television networks such as Discovery Channel, TLC and Animal Planet. Discovery Channel, TLC and Animal Planet collectively generated 67%of U.S. Networks’ total revenue. In addition, this segment holds an equity method interest in OWN: Oprah Winfrey Network ("OWN").U.S. Networks generates revenues from fees charged to distributors of our television networks’ first run content, which include cable, DTH satellite andtelecommunication service providers, referred to as affiliate fees; fees from digital distributors for licensed content that was previously distributed on ourtelevision networks, referred to as digital distribution revenue; fees from advertising sold on our television networks and websites; fees from providing salesrepresentation and network distribution services and content to equity method investee networks; and revenue from licensing our brands for consumerproducts.7Typically, our television networks are aired pursuant to multi-year carriage agreements that provide for the level of carriage that our networks willreceive and for annual graduated rate increases. Carriage of our networks depends on package inclusion, such as whether networks are on the more widelydistributed, broader packages or lesser-distributed, specialized packages, also referred to as digital tiers. In December 2015, we announced our firstauthenticated U.S. TV Everywhere product, Discovery GO, that is available to certain subscribers. Discovery GO connects viewers with live and on-demandaccess to award-winning shows and series from nine U.S. networks in the Discovery portfolio: Discovery Channel, TLC, Animal Planet, ID, Science Channel,Velocity, Destination America, American Heroes Channel ("AHC") and Discovery Life.Advertising revenue is based on the price received for available advertising spots and is dependent upon a number of factors including the number ofsubscribers to our channels, viewership demographics, the popularity of our programming, and our ability to sell commercial time over a portfolio ofchannels. In the U.S., advertising time is sold in the upfront and scatter markets. In the upfront market, advertisers buy advertising time for upcoming seasonsand, by committing to purchase in advance, lock in the advertising rates they will pay for the upcoming year. Many upfront advertising commitments includeoptions whereby advertisers may reduce purchase commitments. In the scatter market, advertisers buy advertising closer to the time when the commercialswill be run, which often results in a pricing premium compared to the upfront rates. The mix of upfront and scatter market advertising time sold is based uponthe economic conditions at the time that upfront sales take place impacting the sell-out levels management is willing or able to obtain. The demand in thescatter market then impacts the pricing achieved for our remaining advertising inventory. Scatter market pricing can vary from upfront pricing and can bevolatile.In addition to the global networks described in the overview section above, we operate networks in the U.S. that utilize the following brands:•Discovery Family Channel reached approximately 67 million subscribers in the U.S. as of December 31, 2015.•Discovery Family Channel provides enriching, cool, relevant, family-friendly entertainment experiences that children and parents can enjoytogether, including animated and live-action series, as well as specials, game shows, and family-favorite movies.•On September 23, 2014, we purchased from Hasbro an additional 10% ownership interest in Discovery Family Channel(formerly known as the HubNetwork), which was previously a 50% owned equity method investee, for $64 million. As a result, we now have a controlling financial interest inDiscovery Family Channel and account for it as a consolidated subsidiary.

Our International Networks segment principally consists of national and pan-regionaltelevision networks. This segment generates revenue from operations in virtually every pay-TV market in the world through an infrastructure that includesoperational centers in London, Warsaw, Milan, Singapore and Miami. Global brands include Discovery Channel, Animal Planet, TLC, ID, Science Channeland Turbo (known as Velocity in the U.S.), along with brands exclusive to International Networks, including Eurosport, Real Time, DMAX and DiscoveryKids. International Networks has a large international distribution platform for its 36 networks, with as many as 14 networks distributed across more than 220countries and territories around the world. Including all acquisitions through December 31, 2015, International Networks operated over 380 uniquedistribution feeds in over 40 languages with channel feeds customized according to language needs and advertising sales opportunities. InternationalNetworks also has free-to-air networks in Europe and the Middle East and broadcast networks in the Nordic countries, which we refer to as the Nordics andcontinues to pursue further international expansion. The penetration and growth rates of pay-TV services vary across the 220 countries and territoriesdepending on the dominance of different television platforms in local markets. While pay-TV services have greater penetration in certain markets, free-to-airor broadcast television is dominant in others. International Networks pursues distribution across all television platforms based on the specific dynamics oflocal markets and relevant commercial agreements. In addition to the global networks described in the overview section above, we operate networksinternationally that utilize the following brands:•Eurosport is a leading sports entertainment group with the following brands: Eurosport, Eurosport 2 and Eurosportnews, reaching viewers acrossEurope and Asia.•Viewing subscribers reached by each brand as of December 31, 2015 were as follows: Eurosport: 161 million; Eurosport 2: 72 million; andEurosportnews: 11 million.•Eurosport telecasts sporting events with pan-regional appeal and its events focus on winter sports, cycling and tennis, including the Tour de Francecycling tournament and the French and U.S. Open tennis tournaments.•In 2015, we committed to acquire the exclusive broadcast rights across all media platforms throughout Europe for the four Olympic Games between2018 and 2024 for €1.3 billion ($1.5 billion as of December 31, 2015). The broadcast rights exclude the U.K. and France for the Olympic Games in2018 and 2020, and exclude Russia. In addition to free-to-air broadcasts for the Olympic Games, many of these events are set to air on Eurosport'schannels. On February 2, 2016, we announced that we will sub-license from the BBC exclusive pay-TV rights in the U.K. to the 2018 and 2020Olympic Games.•Eurosport and Eurosport 2 are simulcast in HD.10•Eurosport also operates the Eurosport Player, an over-the-top direct-to-consumer platform designed for mobile environments.•As of December 31, 2015, DMAX reached approximately 85 million viewers through free-to-air networks, according to internal estimates.•DMAX is a men’s lifestyle channel in Asia and Europe.•Discovery Kids reached approximately 102 million viewers, according to internal estimates, as of December 31, 2015.•Discovery Kids is a leading children's network in Latin America and Asia.Our International Networks segment also owns and operates the following regional television networks, which reached the following number ofsubscribers and viewers via pay and free-to-air or broadcast networks, respectively as of December 31, 2015: Television Service InternationalSubscribers/Viewers(millions) SBS Nordic Broadcast Networks(a) Broadcast 30 Quest Free-to-air 26 Giallo Free-to-air 25 Frisbee Free-to-air 25 Focus Free-to-air 25 K2 Free-to-air 25 DeeJay TV Free-to-air 25 Discovery Max Free-to-air 19 Discovery World Pay 18 Discovery HD World Pay 19 Shed Pay 12 Discovery History Pay 13 Discovery en Espanol (U.S.) Pay 7 Discovery Familia (U.S.) Pay 6 (a) Number of subscribers corresponds to the sum of the subscribers to each of the SBS Nordic broadcast networks in Sweden, Norway, Finland and Denmark subject toretransmission agreements with pay television providers.Similar to U.S. Networks, a significant source of revenue for International Networks relates to fees charged to operators who distribute our linearnetworks. Such operators primarily include cable and DTH satellite service providers. International television markets vary in their stages of development.Some markets, such as the U.K., are more advanced digital television markets, while11others remain in the analog environment with varying degrees of investment from operators to expand channel capacity or convert to digital technologies.Common practice in some markets results in long-term contractual distribution relationships, while customers in other markets renew contracts annually.Distribution revenue for our International Networks segment is largely dependent on the number of subscribers that receive our networks or content, the ratesnegotiated in the distributor agreements, and the market demand for the content that we provide.The other significant source of revenue for International Networks relates to advertising sold on our television networks, similar to U.S. Networks.Advertising revenue is dependent upon a number of factors, including the development of pay and free-to-air television markets, the number of subscribers toand viewers of our channels, viewership demographics, the popularity of our programming, and our ability to sell commercial time over a group of channels.In certain markets, our advertising sales business operates with in-house sales teams, while we rely on external sales representation services in other markets.In developing television markets, we expect that advertising revenue growth will result from continued subscriber growth, our localization strategy, and theshift of advertising spending from traditional broadcast networks to channels in the multi-channel environment. In relatively mature markets, such as WesternEurope, we anticipate that growth in advertising revenue will come from increasing viewership and advertising pricing on our existing television networks,launching new services and through acquisitions.During 2015, distribution, advertising and other revenues were 53%, 44% and 3%, respectively, of total net revenues for this segment. While theCompany has traditionally operated cable networks, an increasing portion of the Company's international ad revenue is generated by free-to-air or broadcastnetworks. Pay-TV networks and free-to-air or broadcast networks, which include the SBS networks, generated 47% and 49% of International Networks' 2015advertising revenue, respectively. Radio networks generated 4% of International Networks' 2015 advertising revenue.On December 21, 2012, we acquired a 20% ownership interest in Eurosport, which includes both Eurosport International and Eurosport France, whichwas accounted for as an equity method investment. On May 30, 2014, we acquired a controlling 31% interest in Eurosport International for €259 million($351 million) and committed to acquire a similar controlling interest in Eurosport France upon resolution of certain regulatory matters. The outstandingregulatory matters in France were subsequently resolved, and on March 31, 2015, we completed our acquisition of an additional 31% equity interest inEurosport France for €36 million ($38 million), giving us a 51% stake in Eurosport. (See Note 3 to the accompanying consolidated financial statements.) OnOctober 1, 2015, we acquired the remaining 49% of Eurosport for €491 million ($548 million). (See Note 11 to the accompanying consolidated financialstatements.)On April 9, 2013, we acquired the television and radio operations of SBS Nordic from Prosiebensat.1 Media AG for cash of approximately €1.4 billion($1.8 billion), including closing purchase price adjustments. As of the year ended December 31, 2015, we recorded a pre-tax loss of $12 million on the sale ofour radio businesses in Northern Europe to Bauer Media Group ("Bauer") for total consideration, net of cash disposed, of €60 million ($67 million), whichincludes €54 million ($61 million) of net cash received at closing on June 30, 2015 and €6 million ($6 million) for the fair value of contingent consideration.We determined that the disposal did not meet the definition of a discontinued operation because it does not represent a strategic shift that has a significantimpact on our operations and consolidated financial results. (See Note 3 to the accompanying consolidated financial statements.)On October 7, 2015, we recorded a pretax loss of $5 million for the contribution of our Russian business to a joint venture (the “New Russian Business”) witha Russian media company, National Media Group ("NMG"). We now hold a 20% interest in the New Russian Business, which was established to comply withchanges in Russian legislation limiting foreign ownership. We no longer consolidate the contributed Russian business, which was a component of ourInternational Networks operating segment and we will account for our ownership interest in the New Russian Business as an equity method investment. (SeeNote 3 to the accompanying consolidated financial statements.)In 2015, we acquired a 100% equity interest in several other unrelated businesses for total cash and contingent consideration of $91 million, net of cashacquired. The acquisitions included a free-to-air network in Italy, cable networks in Denmark, a free-to-air network in Turkey and a pay-TV sports channel inAsia. (See Note 3 to the accompanying consolidated financial statements.) All acquired businesses are components of our International Networks operatingsegment.On January 10, 2013, we purchased an additional 30% ownership interest in Discovery Japan, which was previously a 50% owned equity methodinvestee. As a result, we now have a controlling financial interest in Discovery Japan and account for it as a consolidated subsidiary. We recognized a $92million gain upon consolidation for the difference in the carrying value and the fair value of the previously held equity interest. (See Note 3 to theaccompanying consolidated financial statements.)Acquisitions are included in our operating results upon their acquisition date and dispositions are excluded from our operating results following theirdisposition date. (See Note 3 to the accompanying consolidated financial statements.)Effective January 1, 2015, we realigned our International Networks management reporting structure into the following regions: Northern Europe, whichincludes primarily the Nordics and U.K.; Southern Europe, which primarily includes Italy and12Spain; Central and Eastern Europe, the Middle East, and Africa (“CEEMEA”), which has been expanded to include Germany; Latin America; Asia-Pacific;and Eurosport. Previously, International Networks’ regional operations reporting structure was segregated into the following regions: Western Europe, whichincluded the U.K. and western European countries; Nordics; CEEMEA; Latin America; Asia-Pacific; and Eurosport. This realignment did not impact ourconsolidated financial statements other than to change the regions in which we describe our operating results for the International Networks segment.EDUCATION AND OTHEREducation and Other generated revenues of $173 million during 2015, which represented 3% of our total consolidated revenues. Education iscomprised of curriculum-based product and service offerings and generates revenues primarily from subscriptions charged to K-12 schools for access to anonline suite of curriculum-based VOD tools, professional development services, digital textbooks and, to a lesser extent, student assessments and publicationof hard copy curriculum-based content. Other is comprised of production studios that develop content for our networks and other television service providersthroughout the world. Our wholly owned production studios provide services to our U.S. Networks and International Networks segments at cost. The revenuesand offsetting expenses associated with these inter-segment production services are not reflected in the results of operations for Education and Other as theyhave been eliminated within the Production Studios operating segment.On November 12, 2015, the Company acquired 5 million shares, or 3.4%, of Lions Gate Entertainment Corp. ("Lionsgate"), an entertainment companyinvolved in the production of movies and television, for $195 million. (See Note 4 to the accompanying consolidated financial statements.)On September 23, 2014, the Company acquired a 50% equity method ownership interest in All3Media, a production studio company, with an enterprisevalue of £556 million ($912 million) as of December 31, 2015 for a cash payment of approximately £90 million ($147 million). All3Media recapitalized itsdebt structure to effect the transaction. (See Note 4 to the accompanying consolidated financial statements.)On February 28, 2014, we acquired Raw TV Limited, a factual entertainment production company in the U.K., to improve the sourcing of content forour networks. (See Note 3 to the accompanying consolidated financial statements.)On November 1, 2013, we acquired an education business in the U.K. to complement our existing service offerings and expand our operationsinternationally. (See Note 3 to the accompanying consolidated financial statements.)Our production studios are an operating segment that has been combined with our Education segment. Neither of these operating segments meet thequantitative thresholds for reporting as a separate reportable segment and are aggregated for reporting purposes to reconcile reporting segments toconsolidated results.CONTENT DEVELOPMENTOur content development strategy is designed to increase viewership, maintain innovation and quality leadership, and provide value for our networkdistributors and advertising customers. Our content is sourced from a wide range of third-party producers, which include some of the world’s leadingnonfiction production companies as well as independent producers, and wholly owned production studios.Our production arrangements fall into three categories: produced, coproduced and licensed. Produced content includes content that we engage thirdparties or wholly owned production studios to develop and produce. We retain editorial control and own most or all of the rights, in exchange for paying alldevelopment and production costs. Coproduced content refers to program rights on which we have collaborated with third parties to finance and developeither because at times world-wide rights are not available for acquisition or we save costs by collaborating with third parties. Licensed content is comprisedof films or series that have been produced by third parties. Payments for sports rights made in advance of the event are recognized as prepaid content licenseassets.International Networks maximizes the use of content from our U.S. Networks. Much of our content tends to be culturally neutral and maintains itsrelevance for an extended period of time. As a result, a significant amount of our content translates well across international borders and is made even moreaccessible through extensive use of dubbing and subtitles in local languages. Our content can be re-edited and updated in a cost-effective manner to providetopical versions of subject matter that can be utilized around the world. International Networks executes a localization strategy by offering content from U.S.Networks, customized content and localized schedules via our distribution feeds. While our International Networks segment maximizes the use of contentfrom U.S. Networks, we also develop local content that is tailored to individual market preferences and license the rights to air films, television series andsporting events from third-party producers.Our largest single cost is content expense, which includes content amortization, content impairments and production costs. We amortize the cost ofcapitalized content rights based on the proportion that the current year's estimated revenues bear to the13estimated remaining total lifetime revenues, which normally results in an accelerated amortization method over the estimated useful lives. However, certainnetworks also utilize a straight-line method of amortization over the estimated useful lives of the content. Content is amortized primarily over periods ofthree to four years. The costs for multi-year sports programming arrangements are expensed when the event is broadcast based on the estimated relative valueof each season in the arrangement. Content assets are reviewed for impairment when impairment indicators are present, such as low viewership or limitedexpected use. Impairment losses are recorded for content asset carrying value in excess of net realizable value.REVENUESWe generate revenues principally from fees charged to operators who distribute our network content, which primarily include cable, DTH satellite,telecommunication and digital service providers and advertising sold on our networks and websites. Other transactions include curriculum-based productsand services, affiliate and advertising sales representation services, production of content, content licenses and the licensing of our brands for consumerproducts. During 2015, distribution, advertising and other revenues were 48%, 47% and 5%, respectively, of consolidated revenues. No individual customerrepresented more than 10% of our total consolidated revenues for 2015, 2014 or 2013.DistributionDistribution revenue includes fees charged for the right to view Discovery's network branded content made available to customers through a variety ofdistribution platforms and viewing devices. The largest component of distribution revenue is comprised of linear distribution services for rights to ournetworks from cable, DTH satellite and telecommunication service providers. We have contracts with distributors representing most cable and satelliteservice providers around the world, including the largest operators in the U.S. and major international distributors. Typically, our television networks areaired pursuant to multi-year carriage agreements that provide for the level of carriage that Discovery’s networks will receive, and, if applicable, for scheduledgraduated annual rate increases. Carriage of our networks depends upon package inclusion, such as whether networks are on the more widely distributed,broader packages or lesser-distributed, specialized packages. Distribution revenues are largely dependent on the rates negotiated in the agreements, thenumber of subscribers that receive our networks or content, and the market demand for the content that we provide. We have provided distributors launchincentives, in the form of cash payments or free periods, to carry our networks.In the U.S., approximately 95% of distribution revenues come from the top 10 distributors, with whom we have agreements that expire at various timesfrom 2016 through 2021. Outside of the U.S., approximately 45% of distribution revenue comes from the top 10 distributors. Distribution fees are typicallycollected ratably throughout the year. International television markets vary in their stages of development. Some, notably the U.K., are more advanced digitalmulti-channel television markets, while others operate in the analog environment with varying degrees of investment from distributors in expanding channelcapacity or converting to digital.Distribution revenue also includes fees charged for bulk content arrangements and other subscription services for episodic content. These digitaldistribution agreements are impacted by the quantity, as well as the quality, of the content Discovery provides.AdvertisingOur advertising revenue consists of consumer advertising, which is sold primarily on a national basis in the U.S. and on a pan-regional or local-language feed basis outside the U.S. Advertising contracts generally have a term of one year or less.In the U.S., we sell advertising time in the upfront and scatter markets. In the upfront market, advertisers buy advertising time for the upcoming seasonand by purchasing in advance often receive discounted rates. In the scatter market, advertisers buy advertising time close to the time when the commercialswill be run and often pay a premium. The mix between the upfront and scatter markets is based upon a number of factors, such as pricing, demand foradvertising time and economic conditions. Outside the U.S., advertisers typically buy advertising closer to the time when the commercials will be run. Indeveloping pay television markets, we expect advertising revenue growth will result from subscriber growth, our localization strategy, and the shift ofadvertising spending from broadcast to pay television. In mature markets, such as the U.S. and Western Europe, high proportions of market penetration anddistribution are unlikely to drive rapid revenue growth. Instead, growth in advertising sales comes from increasing viewership and pricing and launching newservices, either in pay-TV, broadcast, or free-to-air television environments.Advertising revenue is dependent upon a number of factors, including the stage of development of television markets, the popularity of free-to-airtelevision, the number of subscribers to our channels, viewership demographics, the popularity of our content and our ability to sell commercial time over agroup of channels. Revenue from advertising is subject to seasonality, market-based variations and general economic conditions. Advertising revenue istypically highest in the second and fourth14quarters. In some cases, advertising sales are subject to ratings guarantees that require us to provide additional advertising time if the guaranteed audiencelevels are not achieved.We also generate revenue from the sale of advertising on our websites on a stand-alone basis and as part of advertising packages with our televisionnetworks.OtherWe also generate income associated with curriculum-based products and services, the licensing of our brands for consumer products and third-partycontent sales, and content production from our production studios.COMPETITIONProviding television content across various distribution platforms is a highly competitive business worldwide. We experience competition for thedevelopment and acquisition of content, distribution of our content, sale of commercial time on our networks and viewership. Our networks compete withother production studios, other television networks, and the internet for the acquisition of content and creative talent such as writers, producers and directors.Our ability to produce and acquire popular content is an important competitive factor for the distribution of our networks, attracting viewers and the sale ofadvertising. Our success in securing popular content and creative talent depends on various factors such as the number of competitors providing content thattargets the same genre and audience, the distribution of our networks, viewership, and the production, marketing and advertising support we provide.Our networks compete with other television networks, including broadcast, cable and local, for the distribution of our content and fees charged to cabletelevision operators, DTH satellite service providers, and other distributors that carry our network content. Our ability to secure distribution agreements isnecessary to ensure the retention of our audiences. Our contractual agreements with distributors are renewed or renegotiated from time to time in the ordinarycourse of business. Growth in the number of networks distributed, consolidation and other market conditions in the cable and satellite distribution industry,and increased popularity of other platforms may adversely affect our ability to obtain and maintain contractual terms for the distribution of our content thatare as favorable as those currently in place. The ability to secure distribution agreements is dependent upon the production, acquisition and packaging oforiginal content, viewership, the marketing and advertising support and incentives provided to distributors, the product offering across a series of networkswithin a region, and the prices charged for carriage.Our networks and websites compete for the sale of advertising with other television networks, including broadcast, cable and local networks, online andmobile outlets, radio content and print media. Our success in selling advertising is a function of the size and demographics of our audiences, quantitative andqualitative characteristics of the audience of each network, the perceived quality of the network and of the particular content, the brand appeal of the networkand ratings as determined by third-party research companies, prices charged for advertising and overall advertiser demand in the marketplace.Our networks and websites also compete for their target audiences with all forms of content and other media provided to viewers, including broadcast,cable and local networks, pay-per-view and VOD services, DVDs, online activities and other forms of news, information and entertainment.Our education business competes with other providers of curriculum-based products and services to schools. Our production studios compete with otherproduction and media companies for talent.INTELLECTUAL PROPERTYOur intellectual property assets include copyrights in television content, trademarks in brands, names and logos, websites, and licenses of intellectualproperty rights from third parties.We are fundamentally a content company and the protection of our brands and content is of primary importance. To protect our intellectual propertyassets, we rely upon a combination of copyright, trademark, unfair competition, trade secret and Internet/domain name statutes and laws, and contractprovisions. However, there can be no assurance of the degree to which these measures will be successful. Moreover, effective intellectual property protectionmay be either unavailable or limited in certain foreign territories. Policing unauthorized use of our products and services and related intellectual property isdifficult and costly. We seek to limit unauthorized use of our intellectual property through a combination of approaches. However, the steps taken to preventthe infringement of our intellectual property by unauthorized third parties may not work.Third parties may challenge the validity or scope of our intellectual property from time to time, and the success of any such challenges could result inthe limitation or loss of intellectual property rights. Irrespective of their validity, such claims may result in substantial costs and diversion of resources whichcould have an adverse effect on our operations. In addition, piracy, which15encompasses the theft of our signal, and unauthorized use of our content, in the digital environment continues to present a threat to revenues from productsand services based on our intellectual property.REGULATORY MATTERSOur businesses are subject to and affected by regulations of U.S. federal, state and local government authorities, and our international operations aresubject to laws and regulations of the countries and international bodies, such as the European Union, in which we operate. Content networks, such as thoseowned by us, are regulated by the Federal Communications Commission (“FCC”) in certain respects if they are affiliated with a cable television operator.Other FCC regulations, although imposed on cable television operators and direct broadcast satellite ("DBS") operators, affect content networks indirectly.The rules, regulations, policies and procedures affecting our businesses are constantly subject to change. These descriptions are summary in nature and do notpurport to describe all present and proposed laws and regulations affecting our businesses.Program AccessThe FCC’s program access rules prevent a satellite or cable content vendor in which a cable operator has an “attributable” ownership interest fromdiscriminating against unaffiliated multichannel video programming distributors (“MVPDs”), such as cable and DBS operators, in the rates, terms andconditions for the sale or delivery of content. These rules also permit MVPDs to initiate complaints to the FCC against content networks if an MVPD claims itis unable to obtain rights to carry the content network on nondiscriminatory rates, terms or conditions. The FCC allowed a previous blanket prohibition onexclusive arrangements with cable operators to expire in October 2012, but will consider case-by-case complaints that exclusive contracts between cableoperators and cable-affiliated programmers significantly hinder or prevent an unaffiliated MVPD from providing satellite or cable programming.“Must-Carry”/Retransmission ConsentThe Cable Television Consumer Protection and Competition Act of 1992 (the “Act”) imposes “must-carry” regulations on cable systems, requiringthem to carry the signals of most local broadcast television stations in their market. DBS systems are also subject to their own must-carry rules. The FCC’simplementation of “must-carry” obligations requires cable operators and DBS providers to give broadcasters preferential access to channel space. Thisreduces the amount of channel space that is available for carriage of our networks by cable and DBS operators. The Act also established retransmissionconsent, which refers to a broadcaster’s right to require MVPDs, such as cable and satellite operators, to obtain the broadcaster's consent before distributingthe broadcaster's signal to the MVPDs' subscribers. Broadcasters have traditionally used the resulting leverage from demand for their must-have broadcastcontent to obtain carriage for their affiliated networks. Increasingly, broadcasters are additionally seeking substantial monetary compensation for grantingcarriage rights for their must-have broadcast content. Such increased financial demands on distributors reduce the content funds available for independentprogrammers not affiliated with broadcasters, such as us.Closed Captioning and Advertising RestrictionsCertain of our networks must provide closed-captioning of content. Our content and websites intended primarily for children 12 years of age and undermust comply with certain limits on advertising, and commercials embedded in our networks’ content stream adhere to certain standards for ensuring thatthose commercials are not transmitted at louder volumes than our program material. The 21st Century Communications and Video Accessibility Act of 2010requires us to provide closed captioning on certain IP-delivered video content that we offer.Obscenity RestrictionsNetwork distributors are prohibited from transmitting obscene content, and our affiliation agreements generally require us to refrain from includingsuch content on our networks.Violent ProgrammingIn 2007, the FCC issued a report on violence in programing that recommended Congress prohibit the availability of violent programming, includingcable programming, during hours when children are likely to be watching. Recent events have led to a renewed interest by some members of Congress in thealleged effects of violent programming, which could lead to a renewal of interest in limiting the availability of such programming or prohibiting it.Regulation of the InternetWe operate several websites that we use to distribute information about our programs and to offer consumers the opportunity to purchase consumerproducts and services. Internet services are now subject to regulation in the U.S. relating to the privacy and16security of personally identifiable user information and acquisition of personal information from children under 13, including the federal Children's OnlinePrivacy Protection Act and the federal Controlling the Assault of Non-Solicited Pornography and Marketing Act. In addition, a majority of states haveenacted laws that impose data security and security breach obligations. Additional federal and state laws and regulations may be adopted with respect to theInternet or other on-line services, covering such issues as user privacy, child safety, data security, advertising, pricing, content, copyrights and trademarks,access by persons with disabilities, distribution, taxation and characteristics and quality of products and services. In addition, to the extent we offer productsand services to on-line consumers outside the U.S., the laws and regulations of foreign jurisdictions, including, without limitation, consumer protection,privacy, advertising, data retention, intellectual property, and content limitations, may impose additional compliance obligations on us.Foreign Laws and RegulationsThe foreign jurisdictions in which our networks are offered have, in varying degrees, laws and regulations governing our businesses.EMPLOYEESAs of December 31, 2015, we had approximately 7,000 employees, including full-time and part-time employees of our wholly owned subsidiaries andconsolidated ventures.AVAILABLE INFORMATIONAll of our filings with the U.S. Securities and Exchange Commission (the “SEC”), including reports on Form 10-K, Form 10-Q and Form 8-K, and allamendments to such filings are available free of charge at the investor relations section of our website, www.discoverycommunications.com, as soon asreasonably practicable after such material is filed with, or furnished to, the SEC.

Risk Factors.Investing in our securities involves risk. In addition to the other information contained in this report, you should consider the following risk factorsbefore investing in our securities.Consolidation among cable and satellite providers, both domestically and internationally, could have an adverse effect on our revenue andprofitability.Consolidation among cable and satellite operators has given the largest operators considerable leverage in their relationships with programmers,including us. In the U.S., approximately 95% of our distribution revenues come from the top 10 distributors. We currently have agreements in place with themajor U.S. cable and satellite operators which expire at various times through 2021. Some of our largest distributors are combining and have gained, or maygain, market power, which could affect our ability to maximize the value of our content through those platforms. In addition, many of the countries andterritories in which we distribute our networks also have a small number of dominant distributors. Continued consolidation within the industry could reducethe number of distributors to carry our programming, subject our affiliate fee revenue to greater volume discounts, and further increase the negotiatingleverage of the cable and satellite television system operators which could have an adverse effect on our financial condition or results of operations.There has been a shift in consumer behavior as a result of technological innovations and changes in the distribution of content, which may affect ourviewership and the profitability of our business in unpredictable ways.Technology and business models in our industry continue to evolve rapidly. Consumer behavior related to changes in content distribution andtechnological innovation affect our economic model and viewership in ways that are not entirely predictable.17Consumers are increasingly viewing content on a time-delayed or on-demand basis from traditional distributors and from connected apps and websitesand on a wide variety of screens, such as televisions, tablets, mobile phones and other devices. Additionally, devices that allow users to view televisionprograms on a time-shifted basis and technologies that enable users to fast-forward or skip programming, including commercials, such as DVRs and portabledigital devices and systems that enable users to store or make portable copies of content may affect the attractiveness of our offerings to advertisers and couldtherefore adversely affect our revenues. There is increased demand for short-form, user-generated and interactive content, which have different economicmodels than our traditional content offerings. Digital downloads, rights lockers, rentals and subscription services are competing for consumer preferenceswith each other and with traditional physical distribution of DVDs and Blu-ray discs. Each distribution model has different risks and economic consequencesfor us, so the rapid evolution of consumer preferences may have an economic impact that is not completely predictable. Distribution windows are alsoevolving, potentially affecting revenues from other windows. If we cannot ensure that our distribution methods and content are responsive to our targetaudiences, our business could be adversely affected.The success of our business depends on the acceptance of our entertainment content by our U.S. and foreign viewers, which may be unpredictable andvolatile.The production and distribution of entertainment content are inherently risky businesses because the revenue we derive and our ability to distribute ourcontent depend primarily on consumer tastes and preferences that often change in unpredictable ways. Our success depends on our ability to consistentlycreate and acquire content that meets the changing preferences of viewers in general, in special interest groups, in specific demographic categories and invarious international marketplaces. The commercial success of our content also depends upon the quality and acceptance of competing content available inthe applicable marketplace. Other factors, including the availability of alternative forms of entertainment and leisure time activities, general economicconditions, piracy, and growing competition for consumer discretionary spending may also affect the audience for our content. Audience sizes for our medianetworks are critical factors affecting both the volume and pricing of advertising revenue that we receive, and the extent of distribution and the license feeswe receive under agreements with our distributors. Consequently, reduced public acceptance of our entertainment content may decrease our audience shareand adversely affect our results of operations.We face cybersecurity and similar risks, which could result in the disclosure of confidential information, disruption of our programming services,damage to our brands and reputation, legal exposure and financial losses.Our on-line, mobile and app offerings, as well as our internal systems, involve the storage and transmission of proprietary information, and we and ourpartners rely on various technology systems in connection with the production and distribution of our programming. Our systems may be breached due toemployee error, computer malware, viruses, hacking and phishing attacks, or otherwise. Additionally, outside parties may attempt to fraudulently induceemployees or users to disclose sensitive or confidential information in order to gain access to data. Because the techniques used to obtain unauthorizedaccess, disable or degrade service, or sabotage systems change frequently and often are not recognized until launched against a target, we may be unable toanticipate these techniques or to implement adequate preventative measures. Any such breach or unauthorized access could result in a loss of our proprietaryinformation, which may include user data, a disruption of our services or a reduction of the revenues we are able to generate from such services, damage to ourbrands and reputation, a loss of confidence in the security of our offerings and services, and significant legal and financial exposure, each of which couldpotentially have an adverse effect on our business.Our businesses operate in highly competitive industries.The entertainment and media programming industries in which we operate are highly competitive. We compete with other programming networks fordistribution, viewers and advertising. We also compete for viewers with other forms of media entertainment, such as home video, movies, periodicals, on-lineand mobile activities. In particular, websites and search engines have seen significant advertising growth, a portion of which is derived from traditional cablenetwork and satellite advertisers. Businesses, including ours, that offer multiple services, or that may be vertically integrated and offer both video distributionand programming content, may face closer regulatory review from the competition authorities in the countries in which we currently have operations. If ourdistributors have to pay higher rates to holders of sports broadcasting rights, it might be difficult for us to negotiate higher rates for distribution of ournetworks. Our on-line businesses compete for users and advertising in the broad and diverse market of free and subscription Internet-delivered services. Ourcommerce business competes against a wide range of competitive retailers selling similar products. Our curriculum-based video business and digital textbookbusiness compete with other providers of education products to schools. The ability for our businesses to compete successfully depends on a number offactors, including our ability to consistently supply high quality and popular content, access our niche viewership with appealing category-specific content,adapt to new technologies and distribution platforms and achieve widespread distribution. There can be no assurance that we will be able to competesuccessfully in the future against existing or new competitors, or that increasing competition will not have a material adverse effect on our business, financialcondition or results of operations.18Failure to renew, renewal with less favorable terms, or termination of our affiliation agreements may cause a decline in our revenue.Because our networks are licensed on a wholesale basis to distributors, such as cable and satellite operators, which in turn distribute them to consumers,we are dependent upon the maintenance of affiliation agreements with these operators. These affiliation agreements generally provide for the level of carriageour networks will receive, such as channel placement and programming package inclusion (widely distributed, broader programming packages compared tolesser distributed, specialized programming packages) and for payment of a license fee to us based on the number of subscribers that receive our networks.While the number of subscribers associated with our networks impacts our ability to generate advertising revenue, these per subscriber payments alsorepresent a significant portion of our revenue. Our affiliation agreements generally have a limited term which varies by market and distributor, and there canbe no assurance that these affiliation agreements will be renewed in the future, or renewed on terms that are favorable to us. A reduction in the license feesthat we receive per subscriber or in the number of subscribers for which we are paid, including as a result of a loss or reduction in carriage for our networks,could adversely affect our distribution revenue. Such a loss or reduction in carriage could also decrease the potential audience for our programs therebyadversely affecting our advertising revenue. In addition, our affiliation agreements are complex and individually negotiated. If we were to disagree with oneof our counterparties on the interpretation of an affiliation agreement, our relationship with that counterparty could be damaged and our business could benegatively affected.Interpretation of some terms of our distribution agreements may have an adverse effect on the distribution payments we receive under thoseagreements.Some of our distribution agreements contain “most favored nation” clauses. These clauses typically provide that if we enter into an agreement withanother distributor which contains certain more favorable terms, we must offer some of those terms to our existing distributors. We have entered into a numberof distribution agreements with terms that differ in some respects from those contained in other agreements. While we believe that we have appropriatelycomplied with the most favored nation clauses included in our distribution agreements, these agreements are complex and other parties could reach adifferent conclusion that, if correct, could have an adverse effect on our financial condition or results of operations.We are subject to risks related to our international operations.We have operations through which we distribute programming outside the United States. As a result, our business is subject to certain risks inherent ininternational business, many of which are beyond our control. These risks include:•laws and policies affecting trade and taxes, including laws and policies relating to the repatriation of funds and withholding taxes, and changes inthese laws;•changes in local regulatory requirements, including restrictions on content, imposition of local content quotas and restrictions on foreignownership;•differing degrees of protection for intellectual property and varying attitudes towards the piracy of intellectual property;•significant fluctuations in foreign currency value;•currency exchange controls;•the instability of foreign economies and governments;•war and acts of terrorism;•anti-corruption laws and regulations such as the Foreign Corrupt Practices Act and the U.K. Bribery Act that impose stringent requirements on howwe conduct our foreign operations and changes in these laws and regulations;•foreign privacy and data protection laws and regulation and changes in these laws; and•shifting consumer preferences regarding the viewing of video programming.Events or developments related to these and other risks associated with international trade could adversely affect our revenues from non-U.S. sources, whichcould have a material adverse effect on our business, financial condition, operating results, liquidity and prospects.Furthermore, some foreign markets where we and our partners operate may be more adversely affected by current economic conditions than the U.S. We alsomay incur substantial expense as a result of changes, including the imposition of new restrictions, in the existing economic or political environment in theregions where we do business. Acts of terrorism, hostilities, or financial, political, economic or other uncertainties could lead to a reduction in revenue or lossof investment, which could adversely affect our results of operations.Global economic conditions may have an adverse effect on our business.Our business is significantly affected by prevailing economic conditions and by disruptions to financial markets. We derive19substantial revenues from advertisers, and these expenditures are sensitive to general economic conditions and consumer buying patterns. Financialinstability or a general decline in economic conditions in the U.S. and other countries where our networks are distributed could adversely affect advertisingrates and volume, resulting in a decrease in our advertising revenues.Decreases in consumer discretionary spending in the U.S. and other countries where our networks are distributed may affect cable television and othervideo service subscriptions, in particular with respect to digital service tiers on which certain of our programming networks are carried. This could lead to adecrease in the number of subscribers receiving our programming from multi-channel video programming distributors, which could have a negative impacton our viewing subscribers and affiliation fee revenues. Similarly, a decrease in viewing subscribers would also have a negative impact on the number ofviewers actually watching the programs on our programming networks, which could also impact the rates we are able to charge advertisers.Economic conditions affect a number of aspects of our businesses worldwide and impact the businesses of our partners who purchase advertising on ournetworks and might reduce their spending on advertising. Economic conditions can also negatively affect the ability of those with whom we do business tosatisfy their obligations to us. The general worsening of current global economic conditions could adversely affect our business, financial condition or resultsof operations, and the worsening of economic conditions in certain parts of the world, specifically, could impact the expansion and success of our businessesin such areas.Domestic and foreign laws and regulations could adversely impact our operation results.Programming services like ours, and the distributors of our services, including cable operators, satellite operators and other multi-channel videoprogramming distributors, are regulated by U.S. federal laws and regulations issued and administered by various federal agencies, including the FCC, as wellas by state and local governments, in ways that affect the daily conduct of our video content business. See the discussion under “Business – RegulatoryMatters” above. The U.S. Congress, the FCC and the courts currently have under consideration, and may adopt or interpret in the future, new laws, regulationsand policies regarding a wide variety of matters that could, directly or indirectly, affect the operations of our U.S. media properties or modify the terms underwhich we offer our services and operate. For example, any changes to the laws and regulations that govern the services or signals that are carried by cabletelevision operators or our other distributors may result in less capacity for other content services, such as our networks, which could adversely affect ourrevenue.Similarly, the foreign jurisdictions in which our networks are offered have, in varying degrees, laws and regulations governing our businesses.Programming businesses are subject to regulation on a country-by-country basis. Changes in regulations imposed by foreign governments could alsoadversely affect our business, results of operations and ability to expand our operations beyond their current scope.Financial markets are subject to volatility and disruptions that may affect our ability to obtain or increase the cost of financing our operations and ourability to meet our other obligations.Increased volatility and disruptions in the U.S. and global financial and equity markets may make it more difficult for us to obtain financing for ouroperations or investments or increase the cost of obtaining financing. Our borrowing costs can be affected by short and long-term debt ratings assigned byindependent rating agencies which are based, in significant part, on our performance as measured by credit metrics such as interest coverage and leverageratios. A low rating could increase our cost of borrowing or make it more difficult for us to obtain future financing. Unforeseeable changes in foreigncurrencies could negatively impact our results of operations and calculations of interest coverage and leverage ratios.Foreign exchange rate fluctuations may adversely affect our operating results and financial conditions.We have significant operations in a number of foreign jurisdictions and certain of our operations are conducted and certain of our debt obligations aredenominated in foreign currencies. As a result, there is exposure to foreign currency risk as the Company enters into transactions and makes investmentsdenominated in multiple currencies. The value of these currencies fluctuates relative to the U.S. dollar. Our consolidated financial statements aredenominated in U.S. dollars, and to prepare those financial statements we must translate the amounts of the assets, liabilities, net sales, other revenues andexpenses of our operations outside of the U.S. from local currencies into U.S. dollars using exchange rates for the current period. As we have expanded ourinternational operations, our exposure to exchange rate fluctuations has increased. This increased exposure could have an adverse effect on our reportedresults of operations and net asset balances. There is no assurance that downward trending currencies will rebound or that stable currencies will remainunchanged in any period or for any specific market.Our inability to successfully acquire and integrate other businesses, assets, products or technologies could harm our operating results.Our success may depend on opportunities to buy other businesses or technologies that could complement, enhance or expand our current business orproducts or that might otherwise offer us growth opportunities. We have acquired, and have made strategic investments in, a number of companies (includingthrough joint ventures) in the past, and we expect to make additional20acquisitions and strategic investments in the future. Such transactions may result in dilutive issuances of our equity securities, use of our cash resources, andincurrence of debt and amortization expenses related to intangible assets. Any acquisitions and strategic investments that we are able to identify andcomplete may be accompanied by a number of risks, including:•the difficulty of assimilating the operations and personnel of acquired companies into our operations;•the potential disruption of our ongoing business and distraction of management;•the incurrence of additional operating losses and operating expenses of the businesses we acquired or in which we invested;•the difficulty of integrating acquired technology and rights into our services and unanticipated expenses related to such integration;•the failure to successfully further develop an acquired business or technology and any resulting impairment of amounts currently capitalized asintangible assets;•the failure of strategic investments to perform as expected or to meet financial projections;•the potential for patent and trademark infringement and data privacy and security claims against the acquired companies, or companies in which wehave invested;•litigation or other claims in connection with acquisitions, acquired companies, or companies in which we have invested;•the impairment or loss of relationships with customers and partners of the companies we acquired or in which we invested or with our customers andpartners as a result of the integration of acquired operations;•the impairment of relationships with, or failure to retain, employees of acquired companies or our existing employees as a result of integration ofnew personnel;•our lack of, or limitations on our, control over the operations of our joint venture companies;•the difficulty of integrating operations, systems, and controls as a result of cultural, regulatory, systems, and operational differences;•in the case of foreign acquisitions and investments, the impact of particular economic, tax, currency, political, legal and regulatory risks associatedwith specific countries; and•the impact of known potential liabilities or liabilities that may be unknown, including as a result of inadequate internal controls, associated with thecompanies we acquired or in which we invested.Our failure to be successful in addressing these risks or other problems encountered in connection with our past or future acquisitions and strategicinvestments could cause us to fail to realize the anticipated benefits of such acquisitions or investments, incur unanticipated liabilities, and harm ourbusiness generally.Our equity method investments' financial performance may differ from current estimates.We have equity investments in certain entities and the accounting treatment applied for these investments varies depending on a number of factors,including, but not limited to, our percentage ownership and the level of influence or control we have over the relevant entity. Any losses experienced bythese entities could adversely impact our results of operations and the value of our investment. In addition, if these entities were to fail and cease operations,we may lose the entire value of our investment and the stream of any shared profits. Some of our ventures may require additional uncommitted funding.We have a significant amount of debt and may incur significant amounts of additional debt, which could adversely affect our financial health and ourability to react to changes in our business.As of December 31, 2015, we had approximately $7.7 billion of consolidated debt, including capital leases. Our substantial level of indebtednessincreases the possibility that we may be unable to generate cash sufficient to pay when due the principal of, interest on, or other amounts associated with ourindebtedness. In addition, we have the ability to draw down our revolving credit facility in the ordinary course, which would have the effect of increasing ourindebtedness. We are also permitted, subject to certain restrictions under our existing indebtedness, to obtain additional long-term debt and working capitallines of credit to meet future financing needs. This would have the effect of increasing our total leverage.Our substantial leverage could have significant negative consequences on our financial condition and results of operations, including:•impairing our ability to meet one or more of the financial ratio covenants contained in our debt agreements or to generate cash sufficient to payinterest or principal, which could result in an acceleration of some or all of our outstanding debt in the event that an uncured default occurs;21•increasing our vulnerability to general adverse economic and market conditions;•limiting our ability to obtain additional debt or equity financing;•requiring the dedication of a substantial portion of our cash flow from operations to service our debt, thereby reducing the amount of cash flowavailable for other purposes;•requiring us to sell debt or equity securities or to sell some of our core assets, possibly on unfavorable terms, to meet payment obligations;•limiting our flexibility in planning for, or reacting to, changes in our business and the markets in which we compete; and•placing us at a possible competitive disadvantage with less leveraged competitors and competitors that may have better access to capital resources.Our ability to incur debt and the use of our funds could be limited by the restrictive covenants in the loan agreement for our revolving credit facility.The loan agreement for our revolving credit facility contains restrictive covenants, as well as requirements to comply with certain leverage and otherfinancial maintenance tests. These covenants and requirements could limit our ability to take various actions, including incurring additional debt,guaranteeing indebtedness and engaging in various types of transactions, including mergers, acquisitions and sales of assets. These covenants could place usat a disadvantage compared to some of our competitors, who may have fewer restrictive covenants and may not be required to operate under these restrictions.Further, these covenants could have an adverse effect on our business by limiting our ability to take advantage of financing, mergers and acquisitions orother opportunities.Theft of our content, including digital copyright theft and other unauthorized exhibitions of our content, may decrease revenue received from ourprogramming and adversely affect our businesses and profitability.The success of our business depends in part on our ability to maintain the intellectual property rights to our entertainment content. We arefundamentally a content company, and piracy of our brands, television networks, digital content and other intellectual property has the potential tosignificantly and adversely affect us. Piracy is particularly prevalent in many parts of the world that lack copyright and other protections similar to existinglaw in the U.S. It is also made easier by technological advances allowing the conversion of content into digital formats, which facilitates the creation,transmission and sharing of high-quality unauthorized copies. Unauthorized distribution of copyrighted material over the Internet is a threat to copyrightowners’ ability to protect and exploit their property. The proliferation of unauthorized use of our content may have an adverse effect on our business andprofitability because it reduces the revenue that we potentially could receive from the legitimate sale and distribution of our content. Litigation may benecessary to enforce our intellectual property rights, protect trade secrets or to determine the validity or scope of proprietary rights claimed by others.The loss of key personnel or talent could disrupt our business and adversely affect our revenue.Our business depends upon the continued efforts, abilities and expertise of our corporate and divisional executive teams and entertainmentpersonalities. We employ or contract with entertainment personalities who may have loyal audiences. These individuals are important to audienceendorsement of our programs and other content. There can be no assurance that these individuals will remain with us or retain their current audiences. If wefail to retain key individuals or if our entertainment personalities lose their current audience base, our operations could be adversely affected.As a holding company, we could be unable to obtain cash in amounts sufficient to meet our financial obligations or other commitments.Our ability to meet our financial obligations and other contractual commitments will depend upon our ability to access cash. We are a holdingcompany, and our sources of cash include our available cash balances, net cash from the operating activities of our subsidiaries, any dividends and interestwe may receive from our investments, availability under our credit facility or any credit facilities that we may obtain in the future and proceeds from any assetsales we may undertake in the future. The ability of our operating subsidiaries, including Discovery Communications, LLC, to pay dividends or to makeother payments or advances to us will depend on their individual operating results and any statutory, regulatory or contractual restrictions, includingrestrictions under our credit facility, to which they may be or may become subject. We are required to accrue and pay U.S. taxes for repatriation of certain cashbalances held by foreign corporations. However, we intend to permanently reinvest these funds outside of the U.S. and our current plans do not demonstrate aneed to repatriate them to fund our U.S. operations.22We have directors in common with those of Liberty Media Corporation (“Liberty Media”), Liberty Global plc (“Liberty Global”), Liberty InteractiveCorporation (“Liberty Interactive”) and Liberty Broadband Corporation ("Liberty Broadband"), which may result in the diversion of businessopportunities or other potential conflicts.Liberty Media, Liberty Global, Liberty Interactive and Liberty Broadband (together, the "Liberty Entities") own interests in various U.S. andinternational companies that have subsidiaries that own or operate domestic or foreign content services that may compete with the content services we offer.We have no rights in respect of U.S. or international content opportunities developed by or presented to the subsidiaries of any Liberty Entities, and thepursuit of these opportunities by such subsidiaries may adversely affect our interests and those of our stockholders. Because we and the Liberty Entities haveoverlapping directors, the pursuit of business opportunities may serve to intensify the conflicts of interest or appearance of conflicts of interest faced by therespective management teams. Our charter provides that none of our directors or officers will be liable to us or any of our subsidiaries for breach of anyfiduciary duty by reason of the fact that such individual directs a corporate opportunity to another person or entity (including any Liberty Entities), for whichsuch individual serves as a director or officer, or does not refer or communicate information regarding such corporate opportunity to us or any of oursubsidiaries, unless (x) such opportunity was expressly offered to such individual solely in his or her capacity as a director or officer of us or any of oursubsidiaries and (y) such opportunity relates to a line of business in which we or any of our subsidiaries is then directly engaged.We have directors that are also related persons of Advance/Newhouse Programming Partnership ("Advance/Newhouse") and that overlap with those ofthe Liberty Entities, which may lead to conflicting interests for those tasked with the fiduciary duties of our board.Our ten-person board of directors includes three designees of Advance/Newhouse, including Robert J. Miron, who was the Chairman ofAdvance/Newhouse until December 31, 2010, and Steven A. Miron, the Chief Executive Officer of Advance/Newhouse. In addition, our board of directorsincludes two persons who are currently members of the board of directors of Liberty Media, three persons who are currently members of the board of directorsof Liberty Global, two persons who are currently members of the board of directors of Liberty Interactive and two persons who are currently members of theboard of directors of Liberty Broadband. John C. Malone is the Chairman of the boards of all of the Liberty Entities. The parent company ofAdvance/Newhouse and the Liberty entities own interests in a range of media, communications and entertainment businesses.Advance/Newhouse will elect three directors annually for so long as it owns a specified minimum amount of our Series A convertible preferred stock.The Advance/Newhouse Series A convertible preferred stock, which votes with our common stock on all matters other than the election of directors,represents approximately 25% of the voting power of our outstanding shares. The Series A convertible preferred stock also grants Advance/Newhouseconsent rights over a range of our corporate actions, including fundamental changes to our business, the issuance of additional capital stock, mergers andbusiness combinations and certain acquisitions and dispositions.None of the Liberty Entities own any interest in us. Mr. Malone beneficially owns stock of Liberty Media representing approximately 47% of theaggregate voting power of its outstanding stock, owns shares representing approximately 25% of the aggregate voting power of Liberty Global, sharesrepresenting approximately 36% of the aggregate voting power of Liberty Interactive, shares representing approximately 46% of the aggregate voting powerof Liberty Broadband and shares representing approximately 21% of the aggregate voting power (other than with respect to the election of the common stockdirectors) of our outstanding stock. Mr. Malone controls approximately 29% of our aggregate voting power relating to the election of our seven commonstock directors, assuming that the preferred stock owned by Advance/Newhouse has not been converted into shares of our common stock. Our directors whoare also directors of the Liberty Entities own stock and stock incentives of the Liberty Entities and own our stock and stock incentives.These ownership interests and/or business positions could create, or appear to create, potential conflicts of interest when these individuals are facedwith decisions that could have different implications for us, Advance/Newhouse and/or the Liberty Entities. For example, there may be the potential for aconflict of interest when we, on the one hand, or Advance/Newhouse and/or one or more of the Liberty Entities, on the other hand, look at acquisitions andother corporate opportunities that may be suitable for the other.The members of our board of directors have fiduciary duties to us and our stockholders. Likewise, those persons who serve in similar capacities atAdvance/Newhouse or a Liberty Entity have fiduciary duties to those companies. Therefore, such persons may have conflicts of interest or the appearance ofconflicts of interest with respect to matters involving or affecting both respective companies, and there can be no assurance that the terms of any transactionswill be as favorable to us or our subsidiaries as would be the case in the absence of a conflict of interest.It may be difficult for a third party to acquire us, even if such acquisition would be beneficial to our stockholders.Certain provisions of our charter and bylaws may discourage, delay or prevent a change in control that a stockholder may consider favorable. Theseprovisions include the following:23•authorizing a capital structure with multiple series of common stock: a Series B that entitles the holders to ten votes per share, a Series A that entitlesthe holders to one vote per share and a Series C that, except as otherwise required by applicable law, entitles the holders to no voting rights;•authorizing the Series A convertible preferred stock with special voting rights, which prohibits us from taking any of the following actions, amongothers, without the prior approval of the holders of a majority of the outstanding shares of such stock:•increasing the number of members of the Board of Directors above ten;•making any material amendment to our charter or by-laws;•engaging in a merger, consolidation or other business combination with any other entity; and•appointing or removing our Chairman of the Board or our Chief Executive Officer;•authorizing the issuance of “blank check” preferred stock, which could be issued by our Board of Directors to increase the number of outstandingshares and thwart a takeover attempt;•classifying our common stock directors with staggered three-year terms and having three directors elected by the holders of the Series A convertiblepreferred stock, which may lengthen the time required to gain control of our Board of Directors;•limiting who may call special meetings of stockholders;•prohibiting stockholder action by written consent (subject to certain exceptions), thereby requiring stockholder action to be taken at a meeting ofthe stockholders;•establishing advance notice requirements for nominations of candidates for election to our Board of Directors or for proposing matters that can beacted upon by stockholders at stockholder meetings;•requiring stockholder approval by holders of at least 80% of our voting power or the approval by at least 75% of our Board of Directors with respectto certain extraordinary matters, such as a merger or consolidation, a sale of all or substantially all of our assets or an amendment to our charter;•requiring the consent of the holders of at least 75% of the outstanding Series B common stock (voting as a separate class) to certain sharedistributions and other corporate actions in which the voting power of the Series B common stock would be diluted by, for example, issuing shareshaving multiple votes per share as a dividend to holders of Series A common stock; and•the existence of authorized and unissued stock which would allow our Board of Directors to issue shares to persons friendly to current management,thereby protecting the continuity of our management, or which could be used to dilute the stock ownership of persons seeking to obtain control ofus.We have also adopted a shareholder rights plan in order to encourage anyone seeking to acquire us to negotiate with our Board of Directors prior toattempting a takeover. While the plan is designed to guard against coercive or unfair tactics to gain control of us, the plan may have the effect of makingmore difficult or delaying any attempts by others to obtain control of us.Holders of any single series of our common stock may not have any remedies if any action by our directors or officers has an adverse effect on only thatseries of common stock.Principles of Delaware law and the provisions of our charter may protect decisions of our Board of Directors that have a disparate impact upon holdersof any single series of our common stock. Under Delaware law, the Board of Directors has a duty to act with due care and in the best interests of all of ourstockholders, including the holders of all series of our common stock. Principles of Delaware law established in cases involving differing treatment ofmultiple classes or series of stock provide that a board of directors owes an equal duty to all common stockholders regardless of class or series and does nothave separate or additional duties to any group of stockholders. As a result, in some circumstances, our directors may be required to make a decision that isadverse to the holders of one series of common stock.

Our portfolio of networks includes prominent television brands such asDiscovery Channel, our most widely distributed global brand, TLC, Animal Planet, Investigation Discovery and Velocity (known as Turbo outside of theU.S.). In 2014, we took a controlling interest in Eurosport, a leading sports entertainment pay-TV programmer across Europe and Asia and in 2015, weacquired an additional 49% of and now own 100% of Eurosport. We also develop and sell curriculum-based education products and services and operateproduction studios.Our objectives are to invest in content for our networks to build viewership, optimize distribution revenue, capture advertising sales and create orreposition branded channels and businesses that can sustain long-term growth and occupy a desired content niche with strong consumer appeal. Our strategyis to maximize the distribution, ratings and profit potential of each of our branded networks. In addition to growing distribution and advertising revenues forour branded networks, we are extending content distribution across new platforms, including brand-aligned websites, web-native networks, on-line streaming,mobile devices, VOD and broadband channels, which provide promotional platforms for our television content and serve as additional outlets for advertisingand distribution revenue. Audience ratings are a key driver in generating advertising revenue and creating demand on the part of cable television operators,DTHsatellite operators, telecommunication service providers, and other content distributors, that deliver our content to their customers.Our content spans genres including survival, exploration, sports, lifestyle, general entertainment, heroes, adventure, crime and investigation, health andkids. We have an extensive library of content and own rights to much of our content and footage, which enables us to exploit our library to launch brands andservices into new markets quickly. Our content can be re-edited and updated in a cost-effective manner to provide topical versions of subject matter that canbe utilized around the world. Substantially all of our content is produced in HD format.Although the Company utilizes certain brands and content globally, we classify our operations in two reportable segments: U.S. Networks, consistingprincipally of domestic television networks and websites, and International Networks, consisting primarily of international television networks and websites;and two combined operating segments referred to as Education and Other, consisting principally of curriculum-based product and service offerings andproduction studios.

Excluding the impact offoreign currency fluctuations, the acquisition of Eurosport and the effect of the consolidation of Discovery Family, distribution revenue increased 7% as aresult of increases of 7% at our U.S. Networks segment and 7% at our International Networks segment. For U.S. Networks, excluding the effect of theconsolidation of Discovery Family, distribution revenue increased primarily due to annual contractual rate increases and, to a lesser extent, increases indigital distribution revenue, partially offset by slight declines in subscribers. The increase in our International Networks' distribution revenue, excluding theimpact of foreign currency and the acquisition of Eurosport, was mostly due to increases in affiliate rates and subscribers, in equivalent amounts, in LatinAmerica, and, a lesser extent, to increases in subscribers in CEEMEA and digital distribution revenue.34Advertising revenue is dependent upon a number of factors, including the stage of development of television markets, the number of subscribers to ourchannels, viewership demographics, the popularity of our content, our ability to sell commercial time over a group of channels, market demand, the mix ofsales of commercial time between the upfront and scatter markets, and economic conditions. These factors impact the pricing and volume of our advertisinginventory. Excluding the impact of foreign currency fluctuations, the acquisition of Eurosport, the effect of the consolidation of Discovery Family, and thedisposition of the Company's radio business, advertising revenue increased 6%, primarily due to increases of 11% at our International Networks segment and,to a lesser extent, increases of 2% at our U.S. Networks segment. The increase at our International Networks segment was mostly driven by pricing and, to alesser extent, ratings in Southern Europe and pricing, volume, and to a lesser extent, ratings in Latin America. Southern Europe and Latin Americacontributed to the increase in equivalent amounts. The increases were also, to a lesser extent, due to pricing in Northern Europe. These increases werepartially offset by decreases due to changes in regulations involving advertising sales operations in Russia, as further described in Item 1, "Business" in thisAnnual Report on Form 10-K. U.S. Networks' advertising revenue increased due to increases in pricing, partially offset by lower audience delivery.Excluding the impact of foreign currency fluctuations, the acquisition of Eurosport, the effect of the consolidation of Discovery Family, and thedisposition of the Company's radio business, other revenue increased 4%. This increase was primarily due to an increase at our Education and Other segmentsdue to increased productions and, to a lesser extent, an increase at our International Networks segment as result of increased program sales. These increaseswere offset by a decrease at our U.S. Networks segment primarily due to the absence of representation service fees for Discovery Family, which have beeneliminated since the Company began to consolidate Discovery Family.Costs of RevenuesExcluding the impact of foreign currency fluctuations, the acquisitions of Eurosport, the effect of the consolidation of Discovery Family, and thedisposition of the Company's radio business, costs of revenues increased 11% as result of increases of 12% at our International Networks segment and 7% atour U.S. Networks segment. The increases in costs of revenues were mostly due to our commitment to increased spending for content on our networks, whichincreased content amortization, and, to a lesser extent, increases in content impairments that were not included in restructuring and other charges. Excludingthe impact of foreign currency fluctuations, the acquisition of Eurosport and the effect of the consolidation of Discovery Family, content amortization was$1,458 million and $1,336 million for the years ended December 31, 2015 and December 31, 2014, respectively. Content amortization rates on our networkshave been slightly accelerating.Selling, General and AdministrativeSelling, general and administrative expenses consist principally of employee costs, marketing costs, research costs, occupancy and back office supportfees. Excluding the impact of foreign currency fluctuations, the acquisition of Eurosport, the consolidation of Discovery Family, and the disposition of theCompany's radio business, selling, general and administrative expenses increased 3% for the year ended December 31, 2015. The increase was primarily dueto an increase in selling, general and administrative expense at our International Networks segment of 10% mostly due to increased personnel and associatedsupport costs and, to a lesser extent, increased marketing costs. The increase was also, to a lesser extent, due to slight increases at our U.S. Network segmentdue to an increase in research and, to a lesser extent, marketing costs. These increases were partially offset by a decrease in our equity-based compensationexpense.Depreciation and AmortizationDepreciation and amortization expense includes depreciation of fixed assets and amortization of finite-lived intangible assets. Excluding the impact offoreign currency fluctuations, business combinations and dispositions, depreciation and amortization remained consistent for the year ended December 31,2015.Restructuring and Other ChargesRestructuring and other charges decreased $40 million. The decrease was primarily due to a decrease in content impairments resulting from the post-acquisition rebranding of The Hub Network to Discovery Family in 2014 (See Note 6 and Note 15 to the accompanying consolidated financial statements.)Loss (Gain) on DispositionLoss on dispositions comprised $12 million for the sale of the SBS Radio business and $5 million for the contribution of the Russian business to a jointventure for the year ended December 31, 2015. Gain on disposition comprised $31 million for the sale of HowStuffWorks for the year ended December 31,2014. (See Note 3 to the accompanying consolidated financial statements.)35Interest ExpenseInterest expense remained consistent for the year ended December 31, 2015 as compared to the year ended December 31, 2014.Income from Equity Investees, NetIncome from our equity method investees declined $22 million, mostly due to losses at All3Media related to the amortization of intangible assets forthe step up in the fair value of assets acquired from the investment following its acquisition on September 23, 2014, interest expense for the recapitalizationof debt for the transaction and losses on derivative instruments. The decline was also, to a lesser extent, due to the change in accounting for Discovery Familyfrom an equity method investment to a consolidated subsidiary, as well as decreased income at various other equity method investees.Other Expense, NetThe table below presents the details of other expense, net (in millions). Year Ended December 31, 2015 2014Foreign currency losses, net $(103) $(22)Gain on derivative instruments 5 1Remeasurement gain on previously held equity interest 2 29Other expense, net (1) (17)Total other expense, net $(97) $(9)Other expense, net increased $88 million in 2015. The increase was primarily due to foreign currency losses related to revaluation of our 1.90% euro-dominated senior notes due March 19, 2027, which expose Discovery to fluctuations in euro exchange rates, as well as the revaluation of monetary assets inVenezuela, due to changes in the bolivar exchange rate used to remeasure revenue and monetary asset balances (as further discussed in Item 7A, "Quantitativeand Qualitative Disclosures about Market Risk" in this Annual Report on Form 10-K). The increase was further attributable to a decrease in remeasurementgain related to the acquisition of a controlling interest in Eurosport on May 30, 2014 of $29 million, and Eurosport France on March 31, 2015 of $2 million(See Note 3 to the accompanying consolidated financial statements). These increases were slightly offset by the attribution expense related to the put rightheld by TF1, the holder of the remaining interests in Eurosport and Eurosport France, as a component of other expense, net in 2014, for which there is nosimilar expense in the 2015.Income TaxesThe following table reconciles the Company's effective income tax rate to the U.S. federal statutory income tax rate. Year Ended December 31, 2015 2014U.S. federal statutory income tax rate 35 % 35 %State and local income taxes, net of federal tax benefit 2 % 2 %Effect of foreign operations 1 % 2 %Domestic production activity deductions (3)% (3)%Change in uncertain tax positions (1)% (1)%Other, net (1)% — %Effective income tax rate 33 % 35 %Income tax expense was $511 million and $610 million and the effective tax rate was 33% and 35% for 2015 and 2014, respectively. The net 2%decrease in the effective tax rate was attributable to a decrease in unrecognized tax benefits as a result of multiple audit resolutions and the lapse of thestatute of limitations in foreign and domestic jurisdictions, favorable impact to deferred taxes due to various enacted foreign legislative changes and theallocation and taxation of income among multiple foreign and domestic jurisdictions.36Segment Results of Operations – 2015 vs. 2014We evaluate the operating performance of our operating segments based on financial measures such as revenues and Adjusted OIBDA. Adjusted OIBDAis defined as operating income excluding: (i) mark-to-market equity-based compensation, (ii) depreciation and amortization, (iii) amortization of deferredlaunch incentives, (iv) restructuring and other charges, (v) certain impairment charges, (vi) gains and losses on business and asset dispositions, and (vii)certain inter-segment eliminations related to production studios. We use this measure to assess the operating results and performance of our segments, performanalytical comparisons, identify strategies to improve performance, and allocate resources to each segment. We believe Adjusted OIBDA is relevant toinvestors because it allows them to analyze the operating performance of each segment using the same metric management uses. We exclude mark-to-marketequity-based compensation, restructuring and other charges, certain impairment charges, and gains and losses on business and asset dispositions from thecalculation of Adjusted OIBDA due to their volatility. We also exclude the depreciation of fixed assets and amortization of intangible assets and deferredlaunch incentives as these amounts do not represent cash payments in the current reporting period. Additionally, certain corporate expenses and inter-segment eliminations related to production studios are excluded from segment results to enable executive management to evaluate segment performancebased upon the decisions of segment executives. Adjusted OIBDA should be considered in addition to, but not a substitute for, operating income, net incomeand other measures of financial performance reported in accordance with U.S. generally accepted accounting principles (“GAAP”).Additional financial information for our segments and geographical areas in which we do business is discussed in Note 21 to the accompanyingconsolidated financial statements included in Item 8, “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K.The table below presents the calculation of total Adjusted OIBDA (in millions).

Changes in stock price are a key driver of fair value estimates used in the attribution of expense for SARs and unit awards. (See Note 13 to theaccompanying consolidated financial statements.)41RESULTS OF OPERATIONS – 2014 vs. 2013Items Impacting ComparabilityOn May 30, 2014, we acquired a controlling interest in Eurosport, and on April 9, 2013, we acquired SBS Nordic (see Note 3 to the accompanyingconsolidated financial statements). We included the operations of Eurosport and SBS Nordic ("Newly Acquired Businesses") in our consolidated financialstatements as of their respective acquisition dates. As a result, Newly Acquired Businesses have impacted the comparability of our results of operationsbetween 2014 and 2013. Accordingly, to assist the reader in understanding the changes in our results of operations, the following tables present thecalculation of comparative adjusted operating income before depreciation and amortization ("Adjusted OIBDA") excluding the Newly Acquired Businesses,as reported within our consolidated financial statements (in millions). The comparability of the results of the U.S. Networks segment was not impacted bythese acquisitions. The column Newly Acquired Businesses for the year ended December 31, 2014 consists of the operating results of Eurosport since itsacquisition on May 30, 2014 and the results of SBS Nordic for the three months ended March 31, 2014. Newly Acquired Businesses do not include DiscoveryFamily, which was acquired on September 23, 2014, the eight days of SBS Nordic's results from April 1, 2013 through April 9, 2013 or other, less significant,acquisitions made during 2014, because their results did not materially impact the comparability of operations, except as otherwise noted within this Item.Adjusted OIBDA is defined and a reconciliation to operating income is presented below in "Segment Results of Operations – 2014 vs. 2013."ConsolidatedYear Ended December 31, 2014 2014 2014 2013 Total CompanyAs Reported NewlyAcquiredBusinesses Total CompanyEx-Acquisitions Total CompanyAs Reported % Change Ex-AcquisitionsRevenues: Distribution$2,842 $244 $2,598 $2,536 2% Advertising3,089 197 2,892 2,739 6% Other334 68 266 260 2%Total Revenues$6,265 $509 $5,756 $5,535 4% Adjusted OIBDA$2,491 $87 $2,404 $2,402 —%International NetworksYear Ended December 31, 2014 2014 2014 2013 InternationalNetworks AsReported NewlyAcquiredBusinesses InternationalNetworks Ex-Acquisitions InternationalNetworksAs Reported % Change Ex-AcquisitionsRevenues: Distribution$1,553 $244 $1,309 $1,242 5 % Advertising1,483 197 1,286 1,162 11 % Other121 68 53 55 (4)%Total Revenues$3,157 $509 $2,648 $2,459 8 % Adjusted OIBDA$1,124 $87 $1,037 $949 9 %42Consolidated Results of Operations – 2014 vs. 2013Our consolidated results of operations for 2014 and 2013 were as follows (in millions). The discussion of our results that follows reflects ourmanagement reporting structure for International Networks prior to January 1, 2015. Effective January 1, 2015, we realigned our International Networksmanagement reporting structure into the following regions: Northern Europe, which includes primarily the Nordic countries, which we refer to as the Nordics,and U.K.; Southern Europe, which primarily includes Italy and Spain; Central and Eastern Europe, the Middle East, and Africa (“CEEMEA”), which has beenexpanded to include Germany; Latin America; Asia-Pacific; and Eurosport. Previously, International Networks’ regional operations reporting structure wassegregated into the following regions: Western Europe, which included the U.K. and western European countries; Nordics; CEEMEA; Latin America; Asia-Pacific; and Eurosport. This realignment did not impact our consolidated financial statements other than to change the regions in which we describe ouroperating results for the International Networks segment from January 1, 2015.

Excluding the impact offoreign currency fluctuations, Newly Acquired Businesses and the effects of the consolidation of Discovery Family, distribution revenue increased 3% as aresult of an increase of 9% at our International Networks segment, partially offset by a decrease of 2% at our U.S. Networks segment. The increase in ourInternational Networks' distribution revenue, excluding the impact of foreign currency and Newly Acquired Businesses, was mostly attributable to revenuegrowth in Latin America and, to a lesser extent, to growth in CEEMEA. The revenue growth in Latin America was due to increases in subscribers and affiliaterates and in CEEMEA was due to increases in subscribers. For U.S. Networks, excluding declines in digital distribution resulting from lower contentdeliveries offset by an increase due to the consolidation of Discovery Family (see Note 3 to the accompanying consolidated financial statements),distribution revenue increased by 6% primarily due to contractual rate increases. Digital distribution revenue, which is earned under agreements to licenseprograms, is recognized when the content has been delivered and is available for use by the customer. Digital distribution revenue is therefore prone tofluctuations based on the timing and volume of content deliveries.43Advertising revenue is dependent upon a number of factors, including the stage of development of television markets, the number of subscribers to ourchannels, viewership demographics, the popularity of our content, our ability to sell commercial time over a group of channels, and the mix of sales ofcommercial time between the upfront and scatter markets, which is based upon a number of factors, such as pricing, demand for advertising time andeconomic conditions. Excluding the impact of foreign currency fluctuations and Newly Acquired Businesses, advertising revenue increased 7% as a result ofincreases of 14% at our International Networks segment and 2% at our U.S. Networks segment. For our International Networks segment, the increase wasmostly due to pricing and ratings increases on our free-to-air networks in Western Europe and, to a lesser extent, pricing increases in the Nordics and volumeincreases in Latin America. For our U.S. Networks segment, the increase was mostly due to increases in pricing and to a lesser extent, the volume ofcommercial units sold, partially offset by lower audience delivery.Excluding the impacts of foreign currency fluctuations and Newly Acquired Businesses, other revenue increased 2%. The increase was primarily due toan increase in revenue at our Education and Other segments due to other business combinations in late 2013 and early 2014, offset by a decrease inrepresentation fees at U.S. Networks.Costs of RevenuesExcluding the impact of foreign currency fluctuations, Newly Acquired Businesses, the effect of the consolidation of Discovery Family and digitaldistribution, costs of revenues increased 10%. The increase was the result of increases of 12% at our International Networks segment, 6% at our U.S. Networkssegment and 20% at our Education and Other segments. The increase in costs of revenues at our International Networks segment was primarily attributable toincreased investment in content acquired from U.S. Networks and locally acquired content, and to a lesser extent, an increase in sales commissions. Theincrease in costs of revenues at our U.S. Networks segment was primarily attributable to an increase in content expense due to additional spending on contentin current and recent periods. These increases were partially offset by decreases in sales commissions.Selling, General and AdministrativeSelling, general and administrative expenses consist principally of employee costs, marketing costs, research costs, occupancy and back office supportfees. Excluding the impact of foreign currency fluctuations and Newly Acquired Businesses, selling, general and administrative expenses decreased 3%. Thedecrease in selling, general and administrative expenses was primarily due to a decrease in equity-based compensation expense and, to a lesser extent, adecrease in marketing expenses. These decreases were partially offset by increases in personnel costs and, to a lesser extent, various other items. The decreasein equity-based compensation expense was due to decreases in our share price.Depreciation and AmortizationDepreciation and amortization expense includes depreciation of fixed assets and amortization of finite-lived intangible assets. Depreciation andamortization expense increased $53 million. The increase was mostly attributable to amortization of intangible assets of businesses acquired during 2014.(See Note 3 to the accompanying consolidated financial statements.)Restructuring and Other ChargesRestructuring and other charges increased $74 million in 2014. The increase was mostly related to content impairments resulting from the postacquisition rebranding of The Hub Network to Discovery Family, and the cancellation of certain high profile series due to legal circumstances pertaining tothe associated talent, and, to a lesser extent, employee terminations associated with the integration of recent acquisitions. (See Note 6 and Note 15 to theaccompanying consolidated financial statements.)Gain on dispositionGain on disposition was $31 million for the sale of HSW and $19 million for the sale of Petfinder for the years ended December 31, 2014 and 2013,respectively. (See Note 3 to the accompanying consolidated financial statements.)Interest ExpenseInterest expense increased $22 million due to an increase in outstanding debt.44Income from Equity Investees, NetIncome from our equity method investees increased $5 million in 2014, due to improved operating results at OWN offset by losses at All3Media relatedto economic hedges that did not receive hedge accounting and the amortization of intangibles for the step up in the fair value of assets acquired.Other Income (Expense), Net The table below presents the details of other income (expense), net (in millions).

The decrease was primarily due to a reduction in remeasurement gains recognized relatedto the acquisition of former equity method investees (see Note 3 of the accompanying consolidated financial statements) and foreign currency losses in 2014,offset by derivative losses related to the acquisition of SBS on April 9, 2013 for which there is no similar item in the current period. The changes in foreigncurrency are primarily driven by the revaluation of monetary assets and liabilities in the Nordic region and Venezuela and, to a lesser extent, Russia.Income TaxesThe following table reconciles the Company's effective income tax rate to the U.S. federal statutory income tax rate. Year Ended December 31, 2014 2013U.S. federal statutory income tax rate 35 % 35 %State and local income taxes, net of federal tax benefit 2 % 3 %Effect of foreign operations 2 % 2 %Domestic production activity deductions (3)% (2)%Change in uncertain tax positions (1)% — %Remeasurement gain on previously held equity interest — % (2)%Other, net — % 2 %Effective income tax rate 35 % 38 %Income tax expense was $610 million and $659 million and the effective tax rates was 35% and 38% for 2014 and 2013, respectively. The net 3%decrease in the effective tax rate was attributable to several factors, including a decline in other, net driven by nondeductible hedging losses associated withthe acquisition of SBS Nordic on April 9, 2013 and the reduction in net deferred tax assets as a result of the change in tax rate in the United Kingdom in theprior year, for which no similar change took place in the current period. Additionally, the decrease for 2014 included a 1% decrease related to the domesticproduction activities deduction following certain legislative changes in 2013. These decreases were partially offset by an increase of 2% in the 2014 tax ratedue to the $92 million remeasurement gain on the previously held equity interest in Discovery Japan recognized upon consolidation in 2013, which was nottaxable because we intend to defer indefinitely the realization of this gain for tax purposes.45Segment Results of Operations – 2014 vs. 2013The table below presents the calculation of total Adjusted OIBDA (in millions).

Excluding declines in digital distribution resulting from lower content deliveries and an increase due to theconsolidation of Discovery Family, distribution revenue increased by 6% primarily due to contractual rate increases, as the subscriber base for the U.S. paytelevision market has declined slightly. Digital distribution revenue, which is earned under agreements to license selected library titles, is recognized whenthe content has been delivered and is available for use by the customer.Advertising revenue increased 2%. The increase was mostly attributable to increases in pricing and, to a lesser extent, the volume of commercial unitssold, partially offset by lower audience delivery.Other revenue decreased 27%. The decrease was mostly attributable to lower representation fees, which have been eliminated now that DiscoveryFamily has been consolidated, as well as decreases in various other items.Costs of RevenuesExcluding the effect of the consolidation of Discovery Family and digital distribution, costs of revenues increased 6% in 2014. The increase wasprimarily attributable to an increase in content expense due to additional spending on content in current and prior years. These increases were partially offsetby decreases in sales commissions.Selling, General and AdministrativeSelling, general and administrative expenses decreased 4% in 2014. The decrease was primarily attributable to decreases in marketing costs.Adjusted OIBDAAdjusted OIBDA decreased 2% in 2014. Revenue for 2014 was consistent with the prior period as increases in advertising revenue were largely offsetby decreases in digital distribution revenue and other revenue. Higher costs in the current year were primarily due to increased content expense, which waspartially offset by lower marketing costs.47International NetworksThe following table presents, for our International Networks operating segment, revenues by type, certain operating expenses, contra revenue amounts,Adjusted OIBDA, and a reconciliation of Adjusted OIBDA to operating income (in millions).

The increase was mostlyattributable to revenue growth in Latin America, and to a lesser extent, to growth in CEEMEA. The revenue growth in Latin America was due to increases insubscribers and affiliate rates, while in CEEMEA it was due to increases in subscribers. Such growth is consistent with the continued development of the paytelevision markets in those regions.Excluding the impact of foreign currency fluctuations and Newly Acquired Businesses, advertising revenue increased 14%. The increase was mostlydue to pricing and ratings increases on our free-to-air networks in Western Europe and, to a lesser extent, pricing increases in the Nordics and volumeincreases in Latin America.Excluding the impact of foreign currency fluctuations and Newly Acquired Businesses, other revenue was consistent with the prior period.Costs of RevenuesExcluding the impact of foreign currency fluctuations and Newly Acquired Businesses, costs of revenues increased 12%. The increase was primarilyattributable to increased investment in U.S. Networks' and locally acquired content in recent years, and to a lesser extent, an increase in sales commissions.Selling, General and AdministrativeExcluding the impact of foreign currency fluctuations and Newly Acquired Businesses, selling, general and administrative expenses remainedcomparable with the prior year. Cost reductions in marketing were offset by increased personnel costs to support a localization strategy as certain activitiesare transitioned out of regional hubs.Adjusted OIBDAExcluding the impact of foreign currency fluctuations and Newly Acquired Businesses, Adjusted OIBDA increased 16%. The increase was due toincreases in advertising revenue and distribution revenue, partially offset by increased content expense, sales commissions and personnel costs.48Education and OtherThe following table presents, for our Education and Other operating segments, revenue, certain operating expenses, Adjusted OIBDA, and areconciliation of Adjusted OIBDA to operating (loss) income (in millions).

Changes in stock price are a key driver of fair value estimates used in the attribution ofexpense for SARs and unit awards. (See Note 13 to the accompanying consolidated financial statements.)LIQUIDITY AND CAPITAL RESOURCESLiquiditySources of CashHistorically, we have generated a significant amount of cash from operations. During the year ended December 31, 2015, we have funded our workingcapital needs primarily through cash flows from operations. As of December 31, 2015, we had $390 million of cash and cash equivalents on hand.49•Senior NotesAs a public company, we may have access to other sources of capital such as the public bond and equity markets. On March 2, 2015, DiscoveryCommunications, LLC ("DCL"), our wholly-owned subsidiary, issued $300 million principal amount of 3.45% senior notes due March 15,2025. Additionally, on March 19, 2015, DCL issued €600 million principal amount ($637 million, at issuance, based on the exchange rate of$1.06 per euro at March 19, 2015) of 1.90% senior notes due March 19, 2027. All of DCL's outstanding senior notes are fully andunconditionally guaranteed on an unsecured and unsubordinated basis by Discovery and contain certain nonfinancial covenants, events ofdefault and other customary provisions.We maintain an effective Registration Statement on Form S-3 that allows us to conduct registered offerings of securities, including debtsecurities, common stock and preferred stock. Access to sufficient capital from the public market is not assured.•Commercial PaperUnder our commercial paper program and subject to market conditions, DCL may issue unsecured commercial paper notes guaranteed by theCompany from time to time up to an aggregate principal amount outstanding at any given time of $1.0 billion. The maturities of these noteswill vary but may not exceed 397 days. The notes may be issued at a discount or at par, and interest rates will vary based on market conditionsand the credit ratings assigned to the notes at the time of issuance. As of December 31, 2015, we had $93 million of commercial paperborrowings outstanding with a weighted average interest rate of approximately 1.10% and maturities of less than 90 days.•Revolving Credit FacilityDuring the year ended December 31, 2015, we had access to a $1.5 billion revolving credit facility. In February 2016, the Company amendedand restated the revolving credit facility to extend DCL's borrowing capacity to $2.0 billion, extend the maturity date to February 4, 2021 andprovide the option for up to two additional 364-day renewal periods. Borrowing capacity under this agreement is reduced by the outstandingborrowings under the commercial paper program.As of December 31, 2015, the Company had outstanding borrowings under the revolving credit facility of $782 million at a weighted averageinterest rate of 1.55%. Borrowings under the revolving credit facility bear interest at rates that vary based on DCL’s periodic debt ratings. DCLalso has the ability to request an increase of the revolving credit facility up to an aggregate additional $1.0 billion, upon the satisfaction ofcertain conditions. All obligations of DCL and the other borrowers under the revolving credit facility are unsecured and are fully andunconditionally guaranteed by Discovery. Borrowings may be used for general corporate purposes.The credit agreement governing the revolving credit facility (the “Credit Agreement”) contains customary representations, warranties andevents of default, as well as affirmative and negative covenants, including limitations on liens, investments, indebtedness, dispositions, affiliatetransactions, dividends and restricted payments. DCL, its subsidiaries and Discovery are also subject to a limitation on mergers, liquidation anddisposals of all or substantially all of their assets. The Credit Agreement also requires DCL to maintain a consolidated interest coverage ratio (asdefined in the Credit Agreement) of no less than 3:00 to 1:00 and a consolidated leverage ratio (as defined in the Credit Agreement) of no morethan 4:50 to 1:00. As of December 31, 2015, Discovery, DCL and the other borrowers were in compliance with all covenants and there were noevents of default under the Credit Agreement.•Notes ReceivableWe have an outstanding note receivable from OWN, our equity method investee, which totals $384 million including interest. During the yearsended December 31, 2015 and 2014, the Company received net repayments from OWN of $82 million and $56 million, respectively.Borrowings are scheduled for repayment four years after the borrowing date to the extent that OWN has excess cash to repay the borrowings thendue.Uses of CashOur primary uses of cash include the creation and acquisition of new content, business acquisitions, repurchases of our capital stock, income taxes,personnel costs, principal and interest on our outstanding senior notes, and funding for various equity method and other investments.50•Content AcquisitionWe plan to continue to invest significantly in the creation and acquisition of new content. During the year ended December 31, 2015, wecommitted to acquire exclusive broadcast rights across all media platforms throughout Europe for the four Olympic Games between 2018 and2024 for €1.3 billion ($1.5 billion as of December 31, 2015). The broadcast rights exclude the U.K. and France for the Olympic Games in 2018and 2020, and exclude Russia. Additional information regarding contractual commitments to acquire content is set forth in “Commitments andOff-Balance Sheet Arrangements” in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in thisAnnual Report on Form 10-K.•Business Combinations and InvestmentsIn 2015, our uses of cash have included business combinations (see Note 3 to the accompanying consolidated financial statements). Due tobusiness combinations in current and prior years, we also have redeemable equity balances of $241 million, which may require the use of cashin the event holders of noncontrolling interests put their interests to the Company. On March 31, 2015, we acquired from TF1 a controllinginterest in Eurosport France by increasing Discovery's ownership stake from 20% to 51% for cash of approximately €36 million ($38 million).On July 22, 2015, TF1 exercised its right to put the entirety of its remaining 49% noncontrolling interest in Eurosport to the Company for €491million ($551 million as of September 30, 2015). On October 1, 2015, the Company closed the transaction for €491 million ($548 million). (SeeNote 11 to the accompanying consolidated financial statements.) The Company borrowed an additional $525 million under the revolving creditfacility on October 1, 2015 in order to facilitate the transaction.•Equity Method InvestmentsWe have interests in various equity method investees and provide funding to those equity method investees from time to time. As ofDecember 31, 2015, we have outstanding advances to and a note receivable from OWN, our equity method investee, which totals $384 millionincluding interest. We may provide additional funding to our equity method investees, if necessary, and expect to recoup amounts funded. (SeeNote 4 to the accompanying consolidated financial statements.)•Available-for-Sale SecuritiesIn 2015, our uses of cash included the acquisition of 5 million shares of an entertainment company for $195 million. As the shares have areadily determinable fair value and the Company has the intent to retain the investment, the shares are classified as available-for-sale ("AFS")securities. In connection with this transaction, we hedged 50% of the shares with an equity collar for $4 million. (See Note 4 to theaccompanying consolidated financial statements.)•Common Stock Repurchase ProgramUnder the Company's stock repurchase program, management is authorized to purchase shares of the Company's common stock from time totime through open market purchases, privately negotiated transactions at prevailing prices, pursuant to one or more accelerated stock repurchaseagreements, or other derivative arrangements as permitted by securities laws and other legal requirements, and subject to stock price, businessand market conditions and other factors. As of December 31, 2015, the Company had repurchased over the life of the program 3 million and 115million shares of Series A and Series C common stock, respectively, for the aggregate purchase price of $171 million and $5.3 billion,respectively. Over the life of the program, authorization under the stock repurchase program has totaled $7.5 billion. As of December 31, 2015,the Company had remaining authorization of approximately $2.0 billion for future repurchases under the existing stock repurchase program, ofwhich $41 million and $2.0 billion will expire on February 3, 2016 and October 8, 2017, respectively. (See Note 12 to the accompanyingconsolidated financial statements.) We have been funding our stock repurchases through a combination of cash on hand, cash generated byoperations and the issuance of debt. In the future we may also choose to fund our stock repurchase program through borrowings under ourrevolving credit facility and future financing transactions.•Preferred Stock Conversion and RepurchaseWe have an agreement with Advance/Newhouse to repurchase, on a quarterly basis, a number of shares of Series C convertible preferred stockconvertible into 3/7 of the number of shares of Series C common stock purchased under the Company’s stock repurchase program during thethen most recently completed fiscal quarter. The price paid per share is calculated as 99% of the average price paid for the Series C commonshares repurchased by the Company during the applicable fiscal quarter multiplied by the Series C conversion rate. The Advance/Newhouserepurchases are made outside of the Company’s publicly announced stock repurchase program. During 2015, we converted and retired 4 millionshares of our Series C convertible preferred stock under the preferred stock conversion and51repurchase arrangement for an aggregate purchase price of $253 million. Based on the number of shares of Series C common stock purchasedduring the three months ended December 31, 2015, the Company expects Advance/Newhouse to effectively convert and sell to the Company 3million shares of its Series C convertible preferred stock for an aggregate purchase price of $159 million on or about February 22, 2016. (SeeNote 12 to the accompanying consolidated financial statements.)•Income Taxes and InterestWe expect to continue to make payments for income taxes and interest on our outstanding senior notes. During the year ended December 31,2015, we made cash payments of $653 million and $312 million for income taxes and interest on our outstanding debt, respectively.•Equity-Based CompensationWe expect to continue to make payments for vested cash-settled equity awards. Actual amounts expensed and payable for cash-settled awardsare dependent on future fair value calculations which are primarily affected by changes in our stock price or changes in the number of awardsoutstanding. During 2015, we paid $25 million for cash-settled equity awards. As of December 31, 2015, we had accrued liabilities of $54million for outstanding cash-settled equity awards, of which $5 million was classified as current. (See Note 13 to the accompanyingconsolidated financial statements.)•Debt MaturitiesOn March 31, 2015, we redeemed $850 million aggregate principal amount of 3.70% senior notes that had an original maturity date of June 1,2015. The repayments included a payment of $1 million for the original issue discount on the Company’s senior notes and resulted in a pretaxloss on extinguishment of debt of $5 million for make-whole premiums.Cash FlowsChanges in cash and cash equivalents were as follows (in millions). Year Ended December 31, 2015 2014 2013Cash and cash equivalents, beginning of period $367 $408 $1,201Cash provided by operating activities 1,277 1,318 1,285Cash used in investing activities (301) (568) (1,987)Cash used in financing activities (902) (734) (85)Effect of exchange rate changes on cash and cashequivalents (51) (57) (6)Net change in cash and cash equivalents 23 (41) (793)Cash and cash equivalents, end of period $390 $367 $408Operating ActivitiesCash provided by operating activities decreased $41 million for the year ended December 31, 2015 as compared to the year ended December 31, 2014.The decrease was primarily attributable to negative foreign currency fluctuations that impacted the Company's operating performance, increased contentinvestment of $90 million and decreases in working capital of $182 million due to decreases in accounts payable and accruals. These decreases were partiallyoffset by a decrease in cash payments for equity-based compensation of $56 million.Cash provided by operating activities increased $33 million for the year ended December 31, 2014 as compared to the year ended December 31, 2013.The increase was primarily attributable to improved operating results and operating cash flows from acquired businesses partially offset by an increase incontent investment of $257 million and taxes paid of $202 million.Investing ActivitiesCash flows used in investing activities decreased $267 million for the year ended December 31, 2015 as compared to the year ended December 31,2014. The decrease was primarily attributable to a decrease in cash paid for business combinations, net of cash acquired of $292 million and a decrease ininvestments in equity method investees of $116 million. These decreases were partially offset by an increase in investments in available-for-sale and costmethod investments of $208 million.52Cash flows used in investing activities decreased $1.4 billion for the year ended December 31, 2014 as compared to the year ended December 31, 2013.The decrease was primarily attributable to decreases in cash paid for business combinations of $1.5 billion, net of cash acquired (see Note 3 to theaccompanying consolidated financial statements) and a decrease in realized losses for derivatives used to economically hedge business combinations of $55million (see Note 10 to the accompanying consolidated financial statements), partially offset by an increase in investments in and advances tounconsolidated equity method investees of $149 million for the investment in a 50% ownership interest in All3Media, a production studio company during2014 (see Note 4 to the accompanying consolidated financial statements).Financing ActivitiesCash flows used in financing activities increased $168 million for the year ended December 31, 2015 as compared to the year ended December 31,2014. The increase was primarily due to the purchase of TF1's 49% noncontrolling interest in Eurosport for $548 million, an increase in net repayments ofcommercial paper of $365 million, an increase in cash distributions to redeemable noncontrolling interests of $40 million and payments on hedginginstruments for derivatives in connection with the effective portion of our interest rate contracts of $29 million (see Note 10 to the accompanyingconsolidated financial statements). These increases were partially offset by increased borrowings under the revolving credit facility of $318 million and adecrease in the repurchases of stock of $471 million.Cash flows used in financing activities increased $649 million for the year ended December 31, 2014 as compared to the year ended December 31,2013. The increase in cash used was primarily due to a reduction in the proceeds from borrowings on an aggregated, net basis from senior notes, commercialpaper and the revolving credit facility of $516 million during 2014 as compared to 2013, as well as an increase in share repurchases of $117 million.Capital ResourcesAs of December 31, 2015, capital resources were comprised of the following (in millions).

There were $782 million in borrowings under the revolving credit facility outstanding as of December 31, 2015.(b) Interest on senior notes is paid annually or semi-annually. Our senior notes outstanding as of December 31, 2015 had interest rates that ranged from 1.90% to 6.35% andwill mature between 2019 and 2043.We expect that our cash balance, cash generated from operations and availability under our revolving credit facility will be sufficient to fund our cashneeds for the next twelve months. Our borrowing costs and access to the capital markets can be affected by short and long-term debt ratings assigned byindependent rating agencies which are based, in part, on our performance as measured by credit metrics, such as interest coverage and leverage ratios.As of December 31, 2015, we held $95 million of our $390 million of cash and cash equivalents in our foreign subsidiaries. We intend to permanentlyreinvest these funds outside of the U.S. Our current plans do not demonstrate a need to repatriate them to the U.S. However, if these funds are needed in theU.S., we would be required to accrue and pay U.S. taxes to repatriate them. The determination of the amount of unrecognized U.S. deferred income taxliability with respect to these undistributed foreign earnings is not practicable.Additional information regarding the changes in our outstanding indebtedness and the significant terms and provisions of our revolving credit facilityand outstanding indebtedness is discussed in Note 9 to the accompanying consolidated financial statements included in Item 8, “Financial Statements andSupplementary Data” in this Annual Report on Form 10-K.53COMMITMENTS AND OFF-BALANCE SHEET ARRANGEMENTSObligationsAs of December 31, 2015, our significant contractual obligations, including related payments due by period, were as follows (in millions). Payments Due by Period Total Less than 1 Year 1-3 Years 3-5 Years More than 5 YearsLong-term debt: Principal payments $6,784 $— $— $1,800 $4,984Interest payments 4,178 301 602 541 2,734Capital lease obligations: Principal payments 142 33 35 42 32Interest payments 33 6 10 10 7Operating lease obligations 281 72 117 79 13Purchase obligations: Content 3,375 768 771 815 1,021Other 1,224 302 477 297 148Total $16,017 $1,482 $2,012 $3,584 $8,939The above table does not include certain long-term obligations as the timing or the amount of the payments cannot be predicted. For example, as ofDecember 31, 2015, we have recorded $241 million for redeemable equity (see Note 11 to the accompanying consolidated financial statements), although weare unable to predict reasonably the ultimate amount or timing of any payment. The current portion of the liability for cash-settled equity-basedcompensation awards was $5 million as of December 31, 2015. Additionally, reserves for unrecognized tax benefits have been excluded from the above tablebecause we are unable to predict reasonably the ultimate amount or timing of settlement. Our unrecognized tax benefits totaled $173 million as ofDecember 31, 2015.The above table also does not include DCL's revolving credit facility that, during the year ended December 31, 2015, allowed DCL and certaindesignated foreign subsidiaries of DCL to borrow up to $1.5 billion, including a $750 million sublimit for multi-currency borrowings, a $100 millionsublimit for the issuance of standby letters of credit and a $50 million sublimit for swingline loans. Borrowing capacity under this agreement is reduced bythe outstanding borrowings under the commercial paper program discussed below. DCL also had the ability to request an increase of the revolving creditfacility up to an aggregate additional $1.0 billion, upon the satisfaction of certain conditions. As of December 31, 2015, the revolving credit facilityagreement provided for a maturity date of June 20, 2019. In February 2016, the Company amended and restated the revolving credit facility to extend DCL'sborrowing capacity up to $2.0 billion, to eliminate the multi-currency borrowing sublimit, to extend the maturity date to February 4, 2021 and to provide theoption to request up to two additional 364-day renewal periods.Lastly, such funding obligations include funding commitments to equity method investees.Long-term DebtPrincipal payments on long-term debt reflect the repayment of our outstanding senior notes, at face value, assuming repayment will occur uponmaturity. Interest payments on our outstanding senior notes are projected based on their contractual rate and maturity.Capital Lease ObligationsWe acquire satellite transponders and other equipment through multi-year capital lease arrangements. Principal payments on capital lease obligationsreflect amounts due under our capital lease agreements. Interest payments on our outstanding capital lease obligations are based on the stated or implied ratein our capital lease agreements.Operating Lease ObligationsWe obtain office space and equipment under multi-year lease arrangements. Most operating leases are not cancelable prior to their expiration. Paymentsfor operating leases represent the amounts due under the agreements assuming the agreements are not canceled prior to their expiration.54Purchase ObligationsContent purchase obligations include commitments and liabilities associated with third-party producers and sports associations for content that airs onour television networks. Production contracts generally require: purchase of a specified number of episodes; payments over the term of the license; andinclude both programs that have been delivered and are available for airing and programs that have not yet been produced or sporting events that have notyet taken place. If the content is ultimately never produced, our commitments expire without obligation. The commitments disclosed above exclude contentliabilities recognized on the consolidated balance sheet. We expect to enter into additional production contracts and content licenses to meet our futurecontent needs.Other purchase obligations include agreements with certain vendors and suppliers for the purchase of goods and services whereby the underlyingagreements are enforceable, legally binding and specify all significant terms. Significant purchase obligations include transmission services, television ratingservices, marketing research, employment contracts, equipment purchases, and information technology and other services. The Company has contracts thatdo not require the purchase of fixed or minimum quantities and generally may be terminated with a 30-day to 60-day advance notice without penalty, and arenot included in the table above past the 30-day to 60-day advance notice period. Amounts related to employment contracts include base compensation anddo not include compensation contingent on future events.Put RightsThe Company has granted put rights related to an equity method investment and certain consolidated subsidiaries. Harpo has the right to require theCompany to purchase all or part of its interest in OWN for fair value during a 90-day window every two and a half years commencing January 1, 2016. Noamounts have been recorded by the Company for the Harpo put right. (See Note 4 to the accompanying consolidated financial statements.) Hasbro andJ:COM have the right to require the Company to purchase their remaining noncontrolling interests in Discovery Family and Discovery Japan, respectively.The Company recorded the value of the put rights for Discovery Family and Discovery Japan as a component of redeemable equity in the amounts of $214million and $26 million, respectively. On July 22, 2015, TF1 exercised its right to put the entirety of its remaining 49% noncontrolling interest in Eurosportto the Company for €491 million ($551 million as of the date redemption became mandatory). The transaction closed on October 1, 2015 for $548 million.(See Note 11 to the accompanying consolidated financial statements.)Off-Balance Sheet ArrangementsWe have no material off-balance sheet arrangements (as defined in Item 303(a)(4) of Regulation S-K) that have or are reasonably likely to have a currentor future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures orcapital resources.RELATED PARTY TRANSACTIONSIn the ordinary course of business we enter into transactions with related parties, primarily our equity method investees and Liberty Media and LibertyGlobal. Information regarding transactions and amounts with related parties is discussed in Note 19 to the accompanying consolidated financial statementsincluded in Item 8, “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K.NEW ACCOUNTING AND REPORTING PRONOUNCEMENTSWe adopted certain accounting and reporting standards during 2015. Information regarding our adoption of new accounting and reporting standards isdiscussed in Note 2 to the accompanying consolidated financial statements included in Item 8, “Financial Statements and Supplementary Data” in thisAnnual Report on Form 10-K.CRITICAL ACCOUNTING POLICIES AND ESTIMATESOur consolidated financial statements are prepared in accordance with GAAP, which requires management to make estimates, judgments andassumptions that affect the amounts reported in the consolidated financial statements included in this Annual Report on Form 10-K and accompanying notes.Management considers an accounting policy to be critical if it is important to reporting our financial condition and results of operations, and if it requiressignificant judgment and estimates on the part of management in its application. The development and selection of these critical accounting policies havebeen determined by management and the related disclosures have been reviewed with the Audit Committee of the Board of Directors of the Company. Weconsider policies relating to the following matters to be critical accounting policies:•Revenue recognition;55•Goodwill and intangible assets;•Income taxes;•Content rights;•Equity-based compensation; and•Equity method investments.With respect to our goodwill accounting policy, we clarify the following:Goodwill is allocated to our reporting units, which are our operating segments or one level below our operating segments. Reporting units aredetermined by the discrete financial information available for the component and whether it is regularly reviewed by segment management. For goodwillimpairment testing purposes, we aggregate certain components or reporting units based on an evaluation of the facts and circumstances, including the natureof products and services, the nature of production processes, the extent of shared assets and resources and similar financial performance. The extent ofeconomic similarities between reporting units impacts the aggregation of these components into a reporting unit. We evaluate goodwill for impairmentannually as of November 30 or earlier upon the occurrence of substantive unfavorable changes in economic conditions, industry trends, costs, cash flows, orongoing declines in market capitalization. If we believe that as a result of our qualitative assessment it is more likely than not that the fair value of a reportingunit is greater than its carrying amount, a quantitative impairment test is not required. Prior to the aggregation of certain reporting units in 2015, ourreporting units were as follows: U.S. Networks, Northern Europe, Southern Europe, CEEMEA, Eurosport, Latin America, Asia-Pacific, Education, Raw, betty,and U.S. Studios.During 2015, we determined that our Northern Europe, Southern Europe, CEEMEA and Eurosport reporting units met the aggregation criteria and weaggregated them into one reporting unit, Europe. In the aggregation assessment, we considered various factors including the nature of the components'operations and the extent to which the components share assets. In 2015 there were significant operational and back-office integration activities with respectto recently acquired businesses such as Eurosport and SBS Nordic, as well as changes in management reporting. European components share content anduplink facilities as well as certain management personnel, and back-office support functions. Investment in research and development projects and theinvestment in the pan-European Olympics rights deal support the growth of all European components. Recently acquired businesses have been integratedinto the European advertising and affiliate sales functions, which determine the selling strategies and revenue growth of the European businesses in theaggregate. We performed a goodwill impairment test on each reporting unit prior to aggregation. No impairments were identified.During 2015, we determined that our production studios, Raw, betty and U.S. Studios, reporting units met the aggregation criteria and we aggregatedthem into one reporting unit. In 2015, the Studios businesses were realigned under a new, single management team to unify strategy. In the aggregationassessment, we considered various factors including the nature of the components' operations, the similarity of operating margins by production genre andthe management structure of the components. Studios components are managed by the studios group executing a broader strategy, operate in a similarmanner, and have similar products and customers. We performed a goodwill impairment test on each reporting unit prior to aggregation. No impairments wereidentified.As a result of the European and Studios aggregations, we reduced the number of our reporting units from eleven to six.For 2015, we performed qualitative assessments prior to aggregation for all but three of our reporting units. Each of these reporting units had a fair valuethat exceeded its respective carrying value by at least 45% as of the date of the last quantitative impairment assessment. Our qualitative assessment included,but was not limited to, consideration of the results of our most recent quantitative impairment test, macroeconomic conditions, industry and marketconditions, cost factors, cash flows, changes in key personnel and our share price. Based on this assessment, we determined that it was more likely than notthat the fair value of those reporting units exceeded their carrying values.We performed a quantitative goodwill impairment assessment for our remaining three reporting units, Eurosport, Raw, and betty, which had aggregategoodwill of $763 million as of November 30, 2015. The first step of the assessment required the comparison of the fair value of a reporting unit with itscarrying amount, including goodwill. In performing the first step, we determined the fair value of these reporting units by using a combination of adiscounted cash flow (“DCF”) analyses and market-based valuation methodologies. Determining fair value requires the Company to make judgments aboutappropriate discount rates, perpetual growth rates, relevant comparable company earnings multiples and the amount and timing of expected future cash flows.The cash flows employed in the DCF analysis are based on the reporting unit's budget, long-term business plan, and recent operating performance. Discountrate assumptions are based on an assessment of the risk inherent in the future cash flows of the respective reporting unit and market conditions. In assessingthe reasonableness of the determined fair values, we also evaluated the results against other value indicators, such as comparable analyst estimates and valuesobserved in market transactions. The fair value of the reporting units exceeded the respective carrying value by 8% to 26%. The reporting unit with fair valuein excess of56carrying value of less than 10% related to a recent acquisition, Eurosport, which was not integrated into another reporting unit prior to this quantitativeassessment. Subsequent to this quantitative impairment assessment, the business was aggregated as a component of the Europe reporting unit. Significantassumptions used in the discounted cash flow analysis included discount rates that ranged from 9% to 15% and long-term growth rates that ranged from 2%to 3.5%.Given the inherent uncertainty in determining the assumptions underlying a DCF analysis, actual results may differ from those used in our valuations.For an in depth discussion of each of our significant accounting policies, including our critical accounting policies and further information regardingestimates and assumptions involved in their application, see Note 2 to the accompanying consolidated financial statements included in Item 8, “FinancialStatements and Supplementary Data” in this Annual Report on Form 10-K.ITEM 7A. Quantitative and Qualitative Disclosures about Market Risk.Our financial position, earnings and cash flows are exposed to market risks and can be affected by, among other things, economic conditions, interestrate changes, foreign currency fluctuations, and changes in the market values of investments. We have established policies, procedures and internal processesgoverning our management of market risks and the use of financial instruments to manage our exposure to such risks.Interest RatesWe are exposed to the impact of interest rate changes primarily through our potential borrowing activities. During the year ended December 31, 2015,we had access to a $1.5 billion revolving credit facility and a commercial paper program with outstanding borrowings of $782 million and $93 million,respectively, as of December 31, 2015. The interest rate on borrowings under the revolving credit facility is variable based on an underlying index and DCL'sthen-current credit rating for its publicly traded debt. In February 2016, the Company amended and restated the revolving credit facility to extend DCL'sborrowing capacity to $2.0 billion, extend the maturity date to February 4, 2021 and add the ability to request up to two additional 364-day renewal periods.As of December 31, 2015, we had outstanding debt book balance of $6.8 billion under various public senior notes with fixed interest rates.Our current objectives in managing exposure to interest rate changes are to limit the impact of interest rates on earnings and cash flows. To achievethese objectives, we may enter into variable interest rate swaps, effectively converting fixed rate borrowings to variable rate borrowings indexed to LIBOR, inorder to reduce the amount of interest paid. As of December 31, 2015 we have no outstanding interest rate swaps.As of December 31, 2015, the fair value of our outstanding public senior notes was $6.6 billion. The fair value of our long-term debt may vary as aresult of market conditions and other factors. A change in market interest rates will impact the fair market value of our fixed rate debt. The potential change infair value of these senior notes from an adverse 100 basis-point change in quoted interest rates across all maturities, often referred to as a parallel shift in theyield curve, would be approximately $542 million as of December 31, 2015.Foreign Currency Exchange RatesWe transact business globally and are subject to risks associated with changing foreign currency exchange rates. Market risk refers to the risk of lossarising from adverse changes in foreign currency exchange rates. The risk of loss can be assessed from the perspective of adverse changes in fair values, cashflows and future earnings. Through December 31, 2015, our International Networks segment is divided into the following five regions: Northern Europe,CEEMEA, Southern Europe, Latin America and Asia-Pacific. Cash is primarily managed from five global locations with net earnings reinvested locally andworking capital requirements met from existing liquid funds. To the extent such funds are not sufficient to meet working capital requirements, draw downs inthe appropriate local currency are available from intercompany borrowings or drawdowns from our revolving credit facility. The earnings of certaininternational operations are expected to be reinvested in those businesses indefinitely. Consequently, we do not hedge our investment in the net assets ofthose foreign operations.The functional currency of most of our international subsidiaries is the local currency. We are exposed to foreign currency risk to the extent that weenter into transactions denominated in currencies other than our subsidiaries’ respective functional currencies ("non-functional currency risk"). Suchtransactions include affiliate and ad sales arrangements, content arrangements, equipment and other vendor purchases and intercompany transactions.Changes in exchange rates with respect to amounts recorded in our consolidated balance sheets related to these items will result in unrealized foreigncurrency transaction gains and losses based upon period-end exchange rates. We also record realized foreign currency transaction gains and losses uponsettlement of the57transactions. Moreover, we will experience fluctuations in our revenues, costs and expenses solely as a result of changes in foreign currency exchange rates.We also are exposed to unfavorable and potentially volatile fluctuations of the U.S. dollar, which is our reporting currency, against the currencies of ouroperating subsidiaries when their respective financial statements are translated into U.S. dollars for inclusion in our consolidated financial statements.Cumulative translation adjustments are recorded in accumulated other comprehensive (loss) income as a separate component of equity. Any increase ordecrease in the value of the U.S. dollar against any foreign functional currency of one of our operating subsidiaries will cause us to experience unrealizedforeign currency translation gains (losses) with respect to amounts already invested in such foreign currencies. Accordingly, we may experience a negativeimpact on our net income, other comprehensive income and equity with respect to our holdings solely as a result of changes in foreign currency.We have operations in Venezuela and, as a result, hold monetary assets denominated in Venezuelan bolivars ("BsF"). Companies operating inVenezuela are required to obtain Venezuelan government approval to exchange BsF into U.S. dollars, and our ability to repatriate cash generated inVenezuela at the official exchange rate is uncertain. In 2014 we applied a devalued exchange rate of 10.7 BsF per U.S. dollar, as established by an alternativecurrency exchange mechanism known as Sistema Complementario de Administracion de Divisas ("SICAD I"), in remeasuring BsF denominated monetaryassets. As of December 31, 2014, we held approximately $30 million in BsF denominated monetary assets, principally in cash and accounts receivable. InFebruary 2015, the Venezuelan government created a new open market foreign exchange system, referred to as "SIMADI" which allowed for trading bolivarsat prices set by the market and merged SICAD I with SICAD II (the “SICAD” exchange mechanism). Beginning April 1, 2015, we applied a devalued SICADexchange rate to remeasure revenue and monetary asset balances. Based upon facts and circumstances, the devalued SICAD rate was the most probablesettlement rate for our transactions. As of December 31, 2015, the Company no longer believes it can successfully convert BsF at the devalued SICAD rateand remeasured BsF denominated monetary assets at the SIMADI exchange rate. The SIMADI rate on December 31, 2015 was 199.5 BsF per U.S. dollar. Thechanges in the BsF exchange rate used by the Company resulted in a foreign currency remeasurement loss of $40 million for BsF denominated monetaryassets during the year ended December 31, 2015; BsF denominated assets total $3 million as of December 31, 2015.In addition to the Venezuelan bolivar, the Company has foreign currency exposure related to other currencies such as the Euro, the British pound,currencies in the Nordics, the Brazilian real, the Japanese yen and the Russian ruble. We may enter into spot, forward and option contracts that change invalue as foreign currency exchange rates change to hedge certain exposures associated with affiliate revenue, the cost for producing or acquiring content,certain intercompany transactions or in connection with forecasted business combinations. These contracts hedge forecasted foreign currency transactions inorder to mitigate fluctuations in our earnings and cash flows associated with changes in foreign currency exchange rates. Our objective in managing exposureto foreign currency fluctuations is to reduce volatility of earnings and cash flows. The net market value of our foreign currency derivative instruments held atDecember 31, 2015 was an asset value of $19 million. Most of our non-functional currency risks related to our revenue, operating expenses and capitalexpenditures that were not hedged as of December 31, 2015. We generally do not hedge against the risk that we may incur non-cash losses upon thetranslation of the financial statements of our subsidiaries and affiliates into U.S. dollars.DerivativesWe may use derivative financial instruments to modify our exposure to market risks from changes in interest rates, foreign currency exchange rates andthe fair value of investments classified as available-for-sale securities. We do not use derivative financial instruments unless there is an underlying exposure.While derivatives are used to mitigate cash flow risk and the risk of declines in fair value, they also limit potential economic benefits to our business in theevent of positive shifts in foreign currency exchange rates, interest rates and market values. We do not hold or enter into financial instruments for speculativetrading purposes.Market Values of InvestmentsIn addition to derivatives, we had investments in entities accounted for using the equity method, available-for-sale securities and other highly liquidinstruments, such as mutual funds, that are accounted for at fair value. The carrying values of investments in equity method investees, available-for-salesecurities and mutual funds were $567 million, $162 million and $149 million, respectively, at December 31, 2015. Investments in mutual funds includeboth fixed rate and floating rate interest earning securities that carry a degree of interest rate risk. Fixed rate securities may have their fair market valueadversely impacted due to a rise in interest rates, while floating rate securities may produce less income than predicted if interest rates fall. Due in part tothese factors, our income from such investments may decrease in the future.58ITEM 8.

(the “Company”) is responsible for establishing and maintaining adequate internal control overfinancial reporting, as such term is defined in Rule 13a-15(f) and Rule 15d-15(f) of the Securities Exchange Act of 1934, as amended. The Company’sinternal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail,accurately and fairly reflect the transactions and disposition of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded asnecessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and provide reasonable assurance thatreceipts and expenditures of the Company are being made only in accordance with authorizations of management and the directors of the Company; and(iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets thatcould have a material effect on the consolidated financial statements.Internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparationof financial statements prepared for external purposes in accordance with generally accepted accounting principles. Because of the inherent limitations inany internal control, no matter how well designed, internal control over financial reporting may not prevent or detect misstatements. Also, projections of anyevaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degreeof compliance with the policies or procedures may deteriorate.The Company’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, conducted an evaluation of theeffectiveness of the Company’s system of internal control over financial reporting as of December 31, 2015 based on the framework set forth in InternalControl – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on its evaluation,management concluded that, as of December 31, 2015, the Company’s internal control over financial reporting was effective at a reasonable assurance levelbased on the specified criteria.The effectiveness of the Company’s internal control over financial reporting as of December 31, 2015 has been audited byPricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report in Item 8 of Part II of this Annual Report on Form 10-K under the caption “Report of Independent Registered Public Accounting Firm.”60REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Board of Directors andStockholders of Discovery Communications, Inc.:In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of comprehensive income, of equityand of cash flows present fairly, in all material respects, the financial position of Discovery Communications, Inc. and its subsidiaries at December 31, 2015and 2014, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2015, in conformity withaccounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effectiveinternal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework (2013) issued bythe Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements,for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting,included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on thesefinancial statements and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordancewith the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtainreasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reportingwas maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts anddisclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overallfinancial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financialreporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on theassessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits providea reasonable basis for our opinions.A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reportingand the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal controlover financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairlyreflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permitpreparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are beingmade only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention ortimely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation ofeffectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliancewith the policies or procedures may deteriorate./s/ PricewaterhouseCoopers LLPMcLean, VirginiaFebruary 18, 201661DISCOVERY COMMUNICATIONS, INC.CONSOLIDATED BALANCE SHEETS(in millions, except par value) December 31, 2015 2014ASSETS Current assets: Cash and cash equivalents $390 $367Receivables, net 1,479 1,433Content rights, net 313 329Deferred income taxes 68 87Prepaid expenses and other current assets 346 275Total current assets 2,596 2,491Noncurrent content rights, net 2,030 1,973Property and equipment, net 488 554Goodwill 8,164 8,236Intangible assets, net 1,730 1,971Equity method investments 567 644Other noncurrent assets 289 101Total assets $15,864 $15,970LIABILITIES AND EQUITY Current liabilities: Accounts payable $282 $225Accrued liabilities 988 1,094Deferred revenues 190 178Current portion of debt 119 1,107Total current liabilities 1,579 2,604Noncurrent portion of debt 7,616 6,002Deferred income taxes 556 588Other noncurrent liabilities 421 425Total liabilities 10,172 9,619Commitments and contingencies (See Note 20.)

DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATIONDescription of BusinessDiscovery Communications, Inc. (“Discovery” or the “Company”) is a global media company that provides content across multiple distributionplatforms, including pay-TV, free-to-air and broadcast television, websites, digital distribution arrangements and content licensing agreements. TheCompany also develops and sells curriculum-based education products and services and operates production studios. The Company classifies its operationsin two reportable segments: U.S. Networks, consisting principally of domestic television networks and websites, and International Networks, consistingprincipally of international television networks and websites; and two combined operating segments referred to as Education and Other, consistingprincipally of curriculum-based product and service offerings and production studios. Financial information for Discovery’s reportable segments is discussedin Note 21.Basis of PresentationThe consolidated financial statements include the accounts of Discovery and its majority-owned subsidiaries in which a controlling interest ismaintained. For each non-wholly owned subsidiary, the Company evaluates its ownership and other interests to determine whether it should consolidate theentity or account for its ownership interest as an investment. As part of its evaluation, the Company makes judgments in determining whether the entity is avariable interest entity ("VIE") and, if so, whether it is the primary beneficiary of the VIE and is thus required to consolidate the entity. (See Note 4.) Inter-company accounts and transactions between consolidated entities have been eliminated in consolidation.NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIESAccounting and Reporting Pronouncements AdoptedAccounting for Fees Paid in a Cloud Computing ArrangementIn April 2015, the Financial Accounting Standards Board ("FASB") issued explicit guidance on the recognition of fees paid by a customerfor cloud computing arrangements as either the acquisition of a software license or a service contract. The Company adopted this guidance effective October1, 2015, and there was no material effect on the consolidated financial statements.Presentation of Debt Issuance CostsIn April 2015, the FASB issued guidance requiring all debt issuance costs to be presented in the balance sheet as a direct deduction from the carryingvalue of the debt instead of being presented as an asset on the balance sheet. The Company retrospectively adopted the new guidance effective April 1, 2015and reclassified its unamortized debt issuance costs related to the Company's debt from other noncurrent assets to noncurrent portion of debt on theconsolidated balance sheets for all periods presented. The balance of unamortized debt issuance costs reclassified as of December 31, 2014 was $44 million.(See Note 9.)Reporting Discontinued OperationsIn April 2014, the FASB issued guidance that changes the criteria for reporting discontinued operations and requires additional disclosures aboutdiscontinued operations and disposals of components of an entity that do not qualify for discontinued operations reporting. Under the new pronouncement,disposal of a component of an entity representing a strategic shift with a major effect on its operations and financial results is a discontinued operation. TheCompany adopted the new guidance on July 1, 2014.The component of an entity that has been disposed or meets the criteria to be classified as held for sale and is presented as a discontinued operationmust represent a strategic shift that has or will have a major effect on the Company's operations and financial results. The results of operations of a componentclassified as discontinued operations, as well as any gain or loss on the disposal transaction, are aggregated for presentation apart from continuing operatingresults of the Company in the consolidated statements of operations for all periods presented. If a discontinued operation is classified as held for sale, theassets and liabilities of the discontinued operation will be presented separately in the statement of financial position for all periods presented. Cash flowsfrom discontinued operations are combined with continuing operations on the consolidated statements of cash flow.Presentation of Unrecognized Tax BenefitsIn July 2013, the FASB issued guidance stating that a liability related to an unrecognized tax benefit should be presented as a reduction to a deferredtax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carry forward to the extent such deferred tax asset is available at the reportingdate to settle any additional income taxes that would result from the67DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSdisallowance of a tax position. The Company prospectively adopted the new guidance effective January 1, 2014. As of December 31, 2014, there were nounrecognized tax benefits reducing deferred tax assets on the consolidated balance sheet.Accounting and Reporting Pronouncements Not Yet AdoptedRecognition and Measurement of Financial InstrumentsIn January 2016, the FASB issued guidance regarding the classification and measurement of financial instruments, which significantly revises theclassification and measurement of investments in equity securities. This standard supersedes the guidance to classify equity securities with readilydeterminable fair values into different categories and requires equity securities to be measured at fair value with changes in the fair value recognized throughnet income. An entity's equity investments that are accounted for under the equity method of accounting or result in consolidation of an investee are notincluded within the scope of this update. The new standard will be effective for reporting periods after December 15, 2017. The Company is currentlyevaluating the impact that the pronouncement will have on the consolidated financial statements.Balance Sheet Classification of Deferred TaxesIn November 2015, the FASB issued guidance to simplify the presentation of deferred income taxes, which removes the requirement to separate deferred taxliabilities and assets into current and noncurrent amounts and instead requires all such amounts be classified as noncurrent on the Company's consolidatedbalance sheets. The new requirement will be effective for financial statements issued for annual periods beginning after December 15, 2016 and can beadopted on either a retrospective or prospective basis. The Company is currently evaluating the impact that the pronouncement will have on the consolidatedfinancial statements.Business ConsolidationIn February 2015, the FASB issued guidance that amends the analysis that a reporting entity performs to determine whether it should consolidatecertain legal entities. The changes in this guidance include how related parties and de facto agents are considered in the primary beneficiary determinationand the analysis for determining whether a fee paid to a decision maker or service provider is a variable interest. The new standard is effective for reportingperiods beginning after December 15, 2015 and can be adopted either retrospectively or using a modified retrospective approach by recording a cumulative-effect adjustment to stockholders' equity as of the beginning of the fiscal year of adoption. Early adoption is permitted. The Company is currently evaluatingthe impact that the pronouncement will have on the consolidated financial statements.Presentation of Financial Statements - Going ConcernIn August 2014, the FASB issued guidance requiring management to perform interim and annual assessments regarding conditions or events that raisesubstantial doubt about the Company's ability to continue as a going concern and to provide related disclosures, if applicable. The new standard will beeffective for reporting periods beginning after December 15, 2016, with early adoption permitted. The adoption of this standard is not expected to have amaterial effect on the Company's consolidated financial statements.Revenue from Contracts with CustomersIn May 2014, the FASB issued guidance which applies a single, comprehensive revenue recognition model for all contracts with customers. Thisstandard contains principles with respect to the measurement of revenue and timing of recognition. The Company will recognize revenue to reflect thetransfer of goods or services to customers at an amount that it expects to be entitled to receive in exchange for those goods or services. In August 2015, theFASB deferred the pronouncement's effective date to annual reporting periods beginning after December 15, 2017. However, reporting entities may choose toadopt the standard as of the original effective date of annual reporting periods beginning after December 15, 2016. The Company is required to apply the newrevenue standard beginning in the first interim period within the year of adoption. The Company is currently evaluating the impact that the pronouncementwill have on the consolidated financial statements.Use of EstimatesThe preparation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires management to makeestimates, judgments and assumptions that affect the amounts and disclosures reported in the consolidated financial statements and accompanying notes.Management continually re-evaluates its estimates, judgments and assumptions and management’s evaluations could change. These estimates are sometimescomplex, sensitive to changes in assumptions and require fair value determinations using Level 3 fair value measurements. Actual results may differmaterially from those estimates.Estimates inherent in the preparation of the consolidated financial statements include accounting for asset impairments, revenue recognition,allowances for doubtful accounts, content rights, depreciation and amortization, business combinations,68DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSequity-based compensation, income taxes, other financial instruments, contingencies, and the determination of whether the Company is the primarybeneficiary of entities in which it holds variable interests.ConsolidationThe Company has ownership and other interests in various entities, including corporations, partnerships, and limited liability companies. For each suchentity, the Company evaluates its ownership and other interests to determine whether it should consolidate the entity or account for its ownership interest asan investment. As part of its evaluation, the Company initially determines whether the entity is a VIE and, if so, whether it is the primary beneficiary of theVIE. An entity is generally a VIE if it meets any of the following criteria: (i) the entity has insufficient equity to finance its activities without additionalsubordinated financial support from other parties, (ii) the equity investors cannot make significant decisions about the entity’s operations, or (iii) the votingrights of some investors are not proportional to their obligations to absorb the expected losses of the entity or receive the expected returns of the entity andsubstantially all of the entity’s activities involve or are conducted on behalf of the investor with disproportionately few voting rights. The Companyconsolidates VIEs for which it is the primary beneficiary, regardless of its ownership or voting interests. The primary beneficiary is the party involved withthe VIE that (i) has the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, and (ii) has the obligation toabsorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant tothe VIE. Upon inception of a variable interest or the occurrence of a reconsideration event, the Company makes judgments in determining whether entities inwhich it invests are VIEs. If so, the Company makes judgments to determine whether it is the primary beneficiary and is thus required to consolidate theentity.If it is concluded that an entity is not a VIE, then the Company considers its proportional voting interests in the entity. The Company consolidatesmajority-owned subsidiaries in which a controlling financial interest is maintained. A controlling financial interest is determined by majority ownership andthe absence of significant third-party participating rights.Ownership interests in entities for which the Company has significant influence that are not consolidated under the Company’s consolidation policyare accounted for as equity method investments. Related party transactions between the Company and its equity method investees have not been eliminated.(See Note 19.)InvestmentsThe Company holds investments in equity method and cost method investees and other marketable securities.Investments in equity method investees are those for which the Company has the ability to exercise significant influence but does not control and isnot the primary beneficiary. Significant influence typically exists if the Company has a 20% to 50% ownership interest in the venture unless persuasiveevidence to the contrary exists. Under this method of accounting, the Company records its proportionate share of the net earnings or losses of equity methodinvestees and a corresponding increase or decrease to the investment balances. Cash payments to equity method investees such as additional investments,loans and advances and expenses incurred on behalf of investees, as well as payments from equity method investees such as dividends, distributions andrepayments of loans and advances are recorded as adjustments to investment balances. The Company evaluates its equity method investments for impairmentwhenever events or changes in circumstances indicate that the carrying amounts of such investments may not be recoverable. (See "Asset ImpairmentAnalysis" below.)Investments in entities or other securities in which the Company has no control or significant influence and is not the primary beneficiary areaccounted for at fair value or cost. Investments in equity securities with readily determinable fair values are accounted for at fair value, based on quotedmarket prices, and classified as either trading securities or available-for-sale securities. For investments classified as trading securities, which includesecurities held in a separate trust in connection with the Company’s deferred compensation plan, unrealized and realized gains and losses related to theinvestment and corresponding liability are recorded in earnings as a component of other (expense) income, net, on the consolidated statements of operations.For investments classified as available-for-sale securities, which include investments in common stock, unrealized gains and losses are recorded net ofincome taxes in other comprehensive (loss) income until the security is sold or considered impaired. If declines in the value of available-for-sale securities aredetermined to be other-than-temporary, a loss is recorded in earnings in the current period as a component of other (expense) income, net on the consolidatedstatements of operations. Impairments are determined based on, among other factors, the length of time the fair value of the investment has been less than thecarrying value, future business prospects for the investee, and information regarding market and industry trends for the investee’s business, if available. Forpurposes of computing realized gains and losses, the Company determines cost on a specific identification basis. Cost method investments are recorded at thelower of cost or fair value. If declines in the value of cost method investments are determined to be other-than-temporary, a loss is recorded in earnings in thecurrent period as a component of other (expense) income, net on the consolidated statements of operations.69DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSForeign CurrencyThe reporting currency of the Company is the U.S. dollar. The functional currency of most of the Company’s international subsidiaries is the localcurrency. Assets and liabilities, including inter-company balances for which settlement is anticipated in the foreseeable future, denominated in foreigncurrencies are translated at exchange rates in effect at the balance sheet date. Foreign currency equity balances are translated at historical rates. Revenues andexpenses denominated in foreign currencies are translated at average exchange rates for the respective periods. Foreign currency translation adjustments arerecorded in accumulated other comprehensive income.Transactions denominated in currencies other than subsidiaries’ functional currencies are recorded based on exchange rates at the time suchtransactions arise. Changes in exchange rates with respect to amounts recorded in the consolidated balance sheets related to these items will result inunrealized foreign currency transaction gains and losses based upon period-end exchange rates. The Company also records realized foreign currencytransaction gains and losses upon settlement of the transactions. Foreign currency transaction gains and losses are included in other (expense) income, netand totaled a loss of $103 million, a loss of $22 million, and a gain of $23 million for 2015, 2014 and 2013, respectively.With the exception of certain material transactions, the cash flows from the Company's operations in foreign countries are translated at the weightedaverage rate for the applicable period in the consolidated statements of cash flows. The impacts of material transactions generally are recorded at theapplicable spot rates in the consolidated statements of operations and cash flows. The effects of exchange rates on cash balances held in foreign currencies areseparately reported in the Company's consolidated statements of cash flows.Cash and Cash EquivalentsCash and cash equivalents include cash on hand and highly liquid investments with original maturities of ninety days or less.ReceivablesReceivables include amounts billed and currently due from customers and are presented net of an estimate for uncollectible accounts. The Companyevaluates outstanding receivables to assess collectability. In performing this evaluation, the Company analyzes market trends, economic conditions, theaging of receivables and customer specific risks. Using this information, the Company reserves an amount that it estimates may not be collected. TheCompany does not require collateral with respect to trade receivables.Content RightsContent rights principally consist of television series, specials and sporting events. Content aired on the Company’s television networks is sourcedfrom a wide range of third-party producers, wholly owned and equity method investee production studios and sports associations. Content is classified eitheras produced, coproduced or licensed. The Company owns most or all of the rights to produced content. The Company collaborates with third parties tofinance and develop coproduced content, and it retains significant rights to exploit the programs. Licensed content is comprised of films or series that havebeen previously produced by third parties and the Company retains limited airing rights over a contractual term. Prepaid licensed content includes advancepayments for rights to air sporting events that will take place in the future and advance payments for acquired films and television series.Costs of produced and coproduced content consist of development costs, acquired production costs, direct production costs, certain productionoverhead costs and participation costs. Costs incurred for produced and coproduced content are capitalized if the Company has previously generatedrevenues from similar content in established markets and the content will be used and revenues will be generated for a period of at least one year. TheCompany’s coproduction arrangements generally provide for the sharing of production costs. The Company records its costs, but does not record the costsborne by the other party as the Company does not share any associated economics of exploitation. Program licenses typically have fixed terms and requirepayments during the term of the license. The cost of licensed content is capitalized when the license period for the programs has commenced and theprograms are available for air or the Company has paid for the programs. The Company pays in advance of delivery for television series, specials, films andsports rights. Payments made in advance of when the right to air the content is received are recognized as in-production produced or coproduced content orprepaid licensed content. Content distribution, advertising, marketing, general and administrative costs are expensed as incurred.Content amortization expense for each period is recognized based on the revenue forecast model, which approximates the proportion that estimateddistribution and advertising revenues for the current period represent in relation to the estimated remaining total lifetime revenues. The Company annually,or on an as needed basis, prepares analyses to support its content amortization expense by network and by region. Critical assumptions used in determiningcontent amortization include: 1) the70DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSapplication of a quantitative revenue forecast model based the adequacy of a network's historical data, 2) determining the appropriate historical periods toutilize and the relative weighting of those historical periods in the revenue forecast model, and 3) assessing the accuracy of the Company's revenue forecasts.The Company then considers the appropriate application of the quantitative assessment given forecasted content use, and expected content investment andmarket trends. Content use and future revenues may differ from estimates based on changes in expectations related to market acceptance, network affiliate feerates, advertising demand, the number of cable and satellite television subscribers receiving the Company’s networks, and program usage. Accordingly, theCompany continually reviews revenue estimates and planned usage and revises its assumptions if necessary. As part of the Company's annual assessment ofthe revenue forecast model, the Company compares the calculated amortization rates to those that have been utilized during the year. If the calculated ratesdo not deviate materially from the applied amortization rates, no adjustment is recorded for the current year amortization expense. The Company allocatesthe cost of multi-year sports programming arrangements over the contract period to each event or season based on the estimated relative value of each eventor season.The result of the revenue forecast model is either an accelerated method or a straight-line amortization method over the estimated useful lives ofprimarily three to four years for produced, coproduced and licensed content. Amortization of capitalized costs for produced and coproduced content beginswhen a program has been aired. Amortization of capitalized costs for licensed content commences when the license period begins and the program isavailable for use. Amortization of sports rights takes place when the content airs.Capitalized content costs are stated at the lower of cost less accumulated amortization or net realizable value. The Company periodically evaluates thenet realizable value of content by considering expected future revenue generation. Estimates of future revenues consider historical airing patterns and futureplans for airing content, including any changes in strategy. Given the significant estimates and judgments involved, actual demand or market conditions maybe less favorable than those projected, requiring a write-down to net realizable value. Development costs for programs that the Company has determined willnot be produced, are fully expensed in the period the determination is made.All produced and coproduced content is classified as long-term. The portion of the unamortized licensed content balance, including prepaid sportsrights, that will be amortized within one year is classified as a current asset.Property and EquipmentProperty and equipment are stated at cost less accumulated depreciation and impairments. The cost of property and equipment acquired under capitallease arrangements represents the lesser of the present value of the minimum lease payments or the fair value of the leased asset as of the inception of thelease. The Company leases fixed assets and software. Capitalized software costs are for internal use. Capitalization of software costs occurs during theapplication development stage. Software costs incurred during the preliminary project and post implementation stages are expensed as incurred. Repairs andmaintenance expenditures that do not enhance the use or extend the life of property and equipment are expensed as incurred.Depreciation for most property and equipment is recognized using the straight-line method over the estimated useful lives of the assets, which is 15 to39 years for buildings, three to five years for broadcast equipment, two to five years for capitalized software costs and three to five years for office equipment,furniture, fixtures and other property and equipment. Assets acquired under capital lease arrangements and leasehold improvements are amortized using thestraight-line method over the lesser of the estimated useful lives of the assets or the terms of the related leases, which is one to 15 years. Depreciationcommences when property or equipment is ready for its intended use.Asset Impairment AnalysisGoodwill and Indefinite-lived Intangible AssetsGoodwill is allocated to the Company's reporting units, which are its operating segments or one level below its operating segments. The Companyevaluates goodwill and other indefinite-lived intangible assets for impairment annually as of November 30 and earlier upon the occurrence of substantivechanges in circumstances, such as a significant deterioration in economic conditions, industry changes, increases in costs, declining cash flows, or asignificant, ongoing decline in market capitalization. If the Company believes that as a result of its qualitative assessment it is more likely than not that thefair value of a reporting unit or other indefinite-lived intangible asset is greater than its carrying amount, the quantitative impairment test is not required.Following a qualitative assessment indicating that it is not more likely than not that the fair value of the reporting unit exceeds its carrying amount,goodwill impairment is determined using a two-step quantitative process. The first step of the process is to compare the fair value of a reporting unit with itscarrying amount, including goodwill. In performing the first step, the Company determines the fair value of a reporting unit by using a combination of adiscounted cash flow (“DCF”) analysis and, if71DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSpossible, market-based valuation methodologies. Determining fair value requires the Company to make judgments about appropriate discount rates,perpetual growth rates, relevant comparable company earnings multiples and the amount and timing of expected future cash flows. The cash flows employedin the DCF analysis are based on the Company’s budget, long-term business plan, and recent operating performance. Discount rate assumptions are based onan assessment of the risk inherent in future cash flows of the respective reporting unit and market conditions. In assessing the reasonableness of its determinedfair values, the Company may also evaluate its results against other value indicators, such as comparable company public trading values, research analystestimates and values observed in market transactions.If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired and the second step of the quantitativeimpairment test is not necessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the quantitative goodwill impairment testis required to be performed to measure the amount of impairment loss, if any. The second step of the quantitative goodwill impairment test compares theimplied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. The implied fair value of goodwill is determined in the samemanner as the amount of goodwill recognized in a business combination. In other words, the estimated fair value of the reporting unit’s identifiable net assetsexcluding goodwill is compared to the fair value of the reporting unit as if the reporting unit had been acquired in a business combination and the fair valueof the reporting unit was the purchase price paid. If the carrying amount of the reporting unit’s goodwill exceeds the implied fair value of that goodwill, animpairment loss is recognized in an amount equal to that excess.Following a qualitative assessment indicating that it is not more likely than not that the fair value of the indefinite lived intangible asset exceeds itscarrying amount, impairment of other intangible assets not subject to amortization involves a comparison of the estimated fair value of the intangible assetwith its carrying value. If the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.The estimates of fair value of intangible assets not subject to amortization are determined using a DCF valuation analysis, a market-based valuation analysis,or both. Determining fair value requires the exercise of judgment about appropriate discount rates, perpetual growth rates and the amount and timing ofexpected future cash flows.Long-lived AssetsLong-lived assets such as amortizing trademarks, customer lists, other intangible assets, and property and equipment are not required to be tested forimpairment annually. Instead, long-lived assets are tested for impairment whenever circumstances indicate that the carrying amount of the asset may not berecoverable, such as when the disposal of such assets is likely or there is an adverse change in the market involving the business employing the related assets.If an impairment analysis is required, the impairment test employed is based on whether the Company’s intent is to hold the asset for continued use or to holdthe asset for sale. If the intent is to hold the asset for continued use, the impairment test first requires a comparison of undiscounted future cash flows to thecarrying value of the asset. If the carrying value of the asset exceeds the undiscounted cash flows, the asset would not be deemed to be recoverable.Impairment would then be measured as the excess of the asset’s carrying value over its fair value. Fair value is typically determined by discounting the futurecash flows associated with that asset. If the intent is to hold the asset for sale and certain other criteria are met, the impairment test involves comparing theasset’s carrying value to its fair value less costs to sell. To the extent the carrying value is greater than the asset’s fair value less costs to sell, an impairmentloss is recognized in an amount equal to the difference. Significant judgments used for long-lived asset impairment assessments include identifying theappropriate asset groupings and primary assets within those groupings, determining whether events or circumstances indicate that the carrying amount of theasset may not be recoverable, determining the future cash flows for the assets involved and determining the proper discount rate to be applied in determiningfair value.Equity Method InvestmentsEquity method investments are reviewed for indicators of other-than-temporary impairment on a quarterly basis. An equity method investment iswritten down to fair value if there is evidence of a loss in value which is other-than-temporary. The Company may estimate the fair value of its equity methodinvestments by considering recent investee equity transactions, discounted cash flow analysis, recent operating results, comparable public companyoperating cash flow multiples and in certain situations, balance sheet liquidation values. If the fair value of the investment has dropped below the carryingamount, management considers several factors when determining whether an other-than-temporary decline has occurred, such as: the length of the time andthe extent to which the estimated fair value or market value has been below the carrying value, the financial condition and the near-term prospects of theinvestee, the intent and ability of the Company to retain its investment in the investee for a period of time sufficient to allow for any anticipated recovery inmarket value and general market conditions. The estimation of fair value and whether an other-than-temporary impairment has occurred requires theapplication of significant judgment and future results may vary from current assumptions. (See Note 4.)72DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSDerivative InstrumentsThe Company uses derivative financial instruments from time to time to modify its exposure to market risks from changes in interest rates, foreigncurrency exchange rates and the fair value of investments classified as available-for-sale securities. The Company may designate derivative instruments ascash flow hedges or fair value hedges, as appropriate. The Company records all derivative instruments at fair value on a gross basis. For those derivativeinstruments designated as cash flow hedges that qualify for hedge accounting, gains or losses on the effective portion of derivative instruments are initiallyrecorded in accumulated other comprehensive loss on the consolidated balance sheets and reclassified to the same account on the consolidated statements ofoperations in which the hedged item is recognized on the consolidated statements of operations. For those derivative instruments designated as fair valuehedges that qualify for hedge accounting, the changes in the fair value of the derivative instruments, including offsetting changes in fair value of the hedgeditems and amounts excluded from the assessment of effectiveness are recorded in other (expense) income, net. The Company may also enter into derivativeinstruments that are not designated as hedges and do not qualify for hedge accounting. These contracts are intended to mitigate economic exposures of theCompany. The changes in fair value of derivatives not designated as hedges and the ineffective portion of derivatives designated as hedging instruments areimmediately recorded in other (expense) income, net.Treasury StockWhen stock is acquired for purposes other than formal or constructive retirement, the purchase price of the acquired stock is recorded in a separatetreasury stock account, which is separately reported as a reduction of equity.When stock is retired or purchased for constructive retirement, the purchase price is initially recorded as a reduction to the par value of the sharesrepurchased, with any excess purchase price over par value recorded as a reduction to additional paid-in capital related to the series of shares repurchased andany remainder excess purchase price recorded as a reduction to retained earnings. If the purchase price exceeds the amounts allocated to par value andadditional paid-in capital related to the series of shares repurchased and retained earnings, the remainder is allocated to additional paid-in capital related toother series of shares.Revenue RecognitionThe Company generates revenues principally from (i) fees charged to distributors of its network content, which include cable, direct-to-home ("DTH")satellite, telecommunications and digital service providers, (ii) advertising sold on its television networks and websites, (iii) transactions for curriculum-based products and services, (iv) production studios content development and services, (v) affiliate and advertising sales representation services and (vi) thelicensing of the Company's brands for consumer products.Revenue is recognized when persuasive evidence of a sales arrangement exists, services are rendered or delivery occurs, the sales price is fixed ordeterminable and collectability is reasonably assured. Revenues do not include taxes collected from customers on behalf of taxing authorities such as salestax and value-added tax. However, certain revenues include taxes that customers pay to taxing authorities on the Company’s behalf, such as foreignwithholding tax. Revenue recognition for each source of revenue is also based on the following policies.DistributionCable operators, DTH satellite and telecommunications service providers typically pay a per-subscriber fee for the right to distribute the Company’sprogramming under the terms of distribution contracts. The majority of the Company’s distribution fees are collected monthly throughout the year anddistribution revenue is recognized over the term of the contracts based on contracted programming rates and reported subscriber levels. The amount ofdistribution fees due to the Company are reported by distributors based on actual subscriber levels. Such information is generally not received until after theclose of the reporting period. In these cases, the Company estimates the number of subscribers receiving the Company’s programming. Historical adjustmentsto recorded estimates have not been material.Distribution revenues are recognized net of incentives the Company provides to operators in exchange for carrying its networks. Incentives includecash payments to operators (“launch incentives”). Launch incentives are capitalized as assets upon launch of the Company’s network by the operator and areamortized on a straight-line basis as a reduction of revenue over the term of the contract, including free periods. In instances where the distribution agreementis extended prior to the expiration of the original term, the Company evaluates the economics of the extended term and, if it is determined that the launchasset continues to benefit the Company over the extended term, then the Company will adjust the amortization period of the remaining launch incentivesaccordingly. Other incentives are recognized as a reduction of revenue as incurred. Amortization of launch incentives was $16 million, $11 million and $18million for 2015, 2014 and 2013, respectively.73DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSRevenues associated with digital distribution arrangements are recognized when the Company transfers control of the content and the rights todistribute the content to the customer. If multiple programs are included in the arrangement, the Company allocates the fee to each program based on itsrelative fair value.AdvertisingAdvertising revenues are principally generated from the sale of bundled commercial time on television networks and websites. Advertising revenues arerecognized net of agency commissions in the period advertising spots are aired. A substantial portion of the advertising contracts in the U.S. guarantee theadvertiser a minimum audience level that either the program in which their advertisements are aired or the advertisement will reach. Revenues are recognizedfor the actual audience level delivered. The Company provides the advertiser with additional advertising spots in future periods if the guaranteed audiencelevel is not delivered. Revenues are deferred for any shortfall in the guaranteed audience level until the guaranteed audience level is delivered or the rightsassociated with the guarantee lapse. Audience guarantees are initially developed internally based on planned programming, historical audience levels, thesuccess of pilot programs, and market trends. In the U.S., actual audience and delivery information is published by independent ratings services. In certaininstances, the independent ratings information is not received until after the close of the reporting period. In these cases, reported advertising revenue andrelated deferred revenue are based upon the Company’s estimates of the audience level delivered. Historical adjustments to recorded estimates have not beenmaterial.Advertising revenues from online properties are recognized as impressions are delivered or the services are performed.OtherRevenue for curriculum-based services is recognized ratably over the contract term as service is provided. Royalties from brand licensing arrangementsare earned as products are sold by the licensee. Revenue from the production studios segment is recognized when the content is delivered and available forairing by the customer.Deferred RevenueDeferred revenue primarily consists of cash received for television advertising for which the advertising spots have not yet fully delivered the ratingsguaranteed, product licensing arrangements and advanced billings to subscribers for access to the Company’s curriculum-based streaming services. Theamounts classified as current are expected to be earned within the next year.Equity-Based Compensation ExpenseThe Company has incentive plans under which unit awards, stock appreciation rights (“SARs”), performance based restricted stock units (“PRSUs”),service based restricted stock units (“RSUs”) and stock options are issued.The Company measures the cost of employee services received in exchange for SARs and unit awards based on the fair value of the award lessestimated forfeitures. Because certain SARs and all unit awards are cash-settled, the Company remeasures the fair value of these awards each reporting perioduntil settlement. Compensation expense, including changes in fair value, for SARs and unit awards is recognized during the vesting period in proportion tothe requisite service that has been rendered as of the reporting date. For awards with graded vesting, the Company measures fair value and recordscompensation expense separately for each vesting tranche.Compensation expense for stock options is attributed to expense over the vesting period based on the fair value on the date of grant less estimatedforfeitures. Compensation expense for stock options is recognized ratably during the vesting period.The fair values of SARs, unit awards and stock options are estimated using the Black-Scholes option-pricing model. Because the Black-Scholes option-pricing model requires the use of subjective assumptions, changes in these assumptions can materially affect the fair value of awards. For SARs and unitawards the expected term is the period from the grant date to the end of the contractual term of the award unless the terms of the award allow for cash-settlement automatically on the date the awards vest, in which case the vesting date is used. For stock options the simplified method is utilized to calculatethe expected term, since the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expectedterm. The simplified method considers the period from the date of grant through the mid-point between the vesting date and the end of the contractual term ofthe award. Expected volatility is based on a combination of implied volatilities from traded options on the Company’s common stock and historical realizedvolatility of the Company’s common stock. The dividend yield is assumed to be zero because the Company has no history of paying cash dividends and nopresent intention to pay dividends. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term equal to the expected termof the award.Vesting for certain PRSUs is subject to satisfying objective operating performance conditions, while vesting for other PRSUs is based on theachievement of a combination of objective and subjective operating performance conditions. Compensation expense for PRSUs that vest based on achievingobjective operating performance conditions is measured based on the fair value of the Company’s Series A and C common stock on the date of grant lessestimated forfeitures. Compensation expense for PRSUs that vest, based on achieving subjective operating performance conditions or in situations where theexecutive is able to withhold taxes74DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSin excess of the minimum statutory requirement, is remeasured at the fair value of the Company’s Series A and Series C common stock, as applicable, lessestimated forfeitures each reporting period until the date of conversion. Compensation expense for all PRSUs is recognized ratably, following a gradedvesting pattern during the vesting period only when it is probable that the operating performance conditions will be achieved. The Company records acumulative adjustment to compensation expense for PRSUs if there is a change in the determination of whether or not it is probable the operatingperformance conditions will be achieved.The Company measures the cost of employee services received in exchange for RSUs based on the fair value of the Company’s Series A common stockon the date of grant less estimated forfeitures. Compensation expense for RSUs is recognized ratably during the vesting period.When recording compensation cost for equity-based awards, the Company is required to estimate the number of awards granted that are expected to beforfeited. In estimating forfeitures, the Company considers historical and expected forfeiture rates and anticipated events. On an ongoing basis, the Companyadjusts compensation expense based on actual forfeitures and revises the forfeiture rate as necessary.The Employee Stock Purchase Plan (the “DESPP”) enables eligible employees to purchase shares of the Company’s common stock through payrolldeductions or other permitted means. The Company recognizes the fair value of the discount associated with shares purchased under the plan as equity-basedcompensation expense.Equity-based compensation expense is recorded as a component of selling, general and administrative expense. The Company classifies the intrinsicvalue of SARs and unit awards that are vested or will become vested within one year as a current liability.Excess tax benefits realized from the exercise of stock options and vested RSUs, PRSUs and the DESPP are reported as cash inflows from financingactivities rather than as a reduction of taxes paid in cash flows from operating activities on the consolidated statements of cash flows.Advertising CostsAdvertising costs are expensed as promotional services are delivered. Advertising costs paid to third parties totaled $148 million, $145 million and$156 million for 2015, 2014 and 2013, respectively.Income TaxesIncome taxes are recorded using the asset and liability method of accounting for income taxes. Deferred income taxes reflect the net tax effect oftemporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.Deferred taxes are measured using rates the Company expects to apply to taxable income in years in which those temporary differences are expected toreverse. A valuation allowance is provided for deferred tax assets if it is more likely than not such assets will be unrealized.From time to time, the Company engages in transactions in which the tax consequences may be uncertain. Significant judgment is required in assessingand estimating the tax consequences of these transactions. The Company prepares and files tax returns based on its interpretation of tax laws and regulations.In the normal course of business, the Company's tax returns are subject to examination by various taxing authorities. Such examinations may result in futuretax and interest assessments by these taxing authorities.In determining the Company's tax provision for financial reporting purposes, the Company establishes a reserve for uncertain tax positions unless theCompany determines that such positions are more likely than not to be sustained upon examination based on their technical merits, including the resolutionof any appeals or litigations processes. There is considerable judgment involved in determining whether positions taken on the Company's tax returns aremore likely than not to be sustained. The Company adjusts its tax reserve estimates periodically because of ongoing examinations by, and settlements with,various taxing authorities, as well as changes in tax laws, regulations and interpretations.Concentrations RiskCustomersThe Company has long-term contracts with distributors around the world. For the U.S. Networks segment, approximately 95% of distribution revenuecomes from the top 10 distributors in the U.S. For the International Networks segment, approximately 45% of distribution revenue comes from the top 10distributors outside the U.S. Agreements in place with the major cable and satellite operators in the U.S. expire at various times beginning in 2016 through2021. Although the Company seeks to renew its agreements with its distributors, a delay in securing a renewal that results in a service disruption, a failure tosecure a renewal or a75DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSrenewal on less favorable terms may have a material adverse effect on the Company’s financial condition and results of operations. Not only could theCompany experience a reduction in distribution revenue, but it could also experience a reduction in advertising revenue, as viewership is impacted byaffiliate subscriber levels.No individual customer accounted for more than 10% of total consolidated revenues for 2015, 2014 and 2013. As of December 31, 2015 and 2014, theCompany’s trade receivables do not represent a significant concentration of credit risk as the customers and markets in which the Company operates arevaried and dispersed across many geographic areas.Financial InstitutionsCash and cash equivalents are maintained with several financial institutions. The Company has deposits held with banks that exceed the amount ofinsurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions of reputablecredit and, therefore, bear minimal credit risk. Additionally, the Company has cash and cash equivalents held by its foreign subsidiaries that would result inU.S. tax consequences should the Company decide it needs to repatriate these funds to the U.S.Lender CounterpartiesThere is a risk that the counterparties associated with the Company’s revolving credit facility will not be available to fund as obligated under the termsof the facility and that the Company may, at the time of such unavailability to fund, have limited or no access to the commercial paper market. If fundingunder the revolving credit facility is unavailable, the Company may have to acquire a replacement credit facility from different counterparties at a higher costor may be unable to find a suitable replacement. Typically, the Company seeks to manage such risks from its revolving credit facility by contracting withexperienced large financial institutions and monitoring the credit quality of its lenders. As of December 31, 2015, the Company did not anticipatenonperformance by any of its counterparties.NOTE 3. ACQUISITIONS AND DISPOSITIONSAcquisitionsEurosportOn December 21, 2012, the Company acquired a 20% equity method investment in Eurosport, which includes both Eurosport International andEurosport France.

The New Russian Business was established to comply with changes in Russian legislation that limit foreign ownership. No cashconsideration was exchanged in the transaction. NMG contributed a free-to-air ("FTA") license which enables advertising for the New Russian Business. Aspart of the transaction, Discovery obtained a 20% ownership interest, which is accounted for under the equity method of accounting. The loss on contributionof the Russian business included $15 million of goodwill allocated to the transaction based on the relative fair values of the Russian business disposed ofand the portion of the reporting unit that was retained. Although Discovery no longer consolidates the Russian business, Discovery earns revenue byproviding content and brands to the New Russian Business under long-term licensing arrangements. The Russian business was included in the InternationalNetworks reportable segment; the licensing arrangements are reported as distribution revenue in the International Networks reportable segment. (See Note21.)RadioOn June 30, 2015, Discovery sold its radio businesses in Northern Europe to Bauer Media Group ("Bauer") for total consideration, net of cash disposedof €60 million ($67 million), which includes €54 million ($61 million) of net cash received at closing and €6 million ($6 million) for the fair value ofcontingent consideration. The final amount of contingent consideration payable, up to a maximum of €18 million ($19 million), will be based on 2015financial results of the radio business, which have not yet been finalized, and is subject to a dispute resolution process under the purchase agreement.Discovery recorded a pretax loss of $12 million upon completion of the sale, which includes adjustments to the fair value of contingent considerationreceivable and working capital adjustments. The loss on the disposal of the radio business includes $26 million of goodwill allocated to the transactionbased on the relative fair values of the radio business disposed of and the portion of the reporting unit that was retained.The Company determined that the disposal did not meet the definition of a discontinued operation because it did not represent a strategic shift that hada significant impact on the Company's operations and consolidated financial results. The income before income taxes impact of the Company's radiobusinesses was zero and losses of $5 million and $9 million for the years ended December 31, 2015, 2014 and 2013, respectively.

(See Note 14.)Equity Method InvestmentsIn the normal course of business, the Company makes investments that support its underlying business strategy and enable it to enter new markets anddevelop programming. All equity method investees are privately owned. The carrying values of the Company’s equity method investments are consistentwith its ownership in the underlying net assets of the investees, except for OWN because the Company has recorded losses in excess of its ownership interest.Certain of the Company's equity method investments are VIEs, for which the Company is not the primary beneficiary. As of December 31, 2015, theCompany’s estimated risk of loss for all its VIEs including the investment carrying values, unfunded contractual commitments, and guarantees made onbehalf of VIEs was approximately $433 million. The Company's estimated risk of loss excludes the non-contractual future funding of VIEs. The aggregatecarrying values of these VIE equity method investments were $423 million and $461 million as of December 31, 2015 and 2014, respectively. The Companyrecognized its portion of net income and losses generated by VIEs of $30 million in income, $45 million in income and $10 million in losses for 2015, 2014and 2013, respectively, in income from equity investees, net on the consolidated statements of operations.OWNOWN is a pay-TV network and website that provides adult lifestyle content, which is focused on self-discovery, self-improvement and entertainment.Since the initial equity was not sufficient to fund OWN's activities without additional subordinated financial support in the form of a note receivable held bythe Company, OWN is a VIE. While the Company and Harpo, Inc. ("Harpo") are partners who share equally in voting control, power is not shared becauseHarpo holds operational rights related to programming and marketing, as well as selection and retention of key management, that significantly impact OWN’seconomic performance. Accordingly, the Company has determined that it is not the primary beneficiary of OWN and accounts for81DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSits investment in OWN using the equity method. However, the Company provides OWN content licenses and services, such as distribution, sales andadministrative support, for a fee and has provided OWN funding. (See Note 19.)The Company's combined advances to and note receivable from OWN, including accrued interest, were $384 million and $457 million as ofDecember 31, 2015 and December 31, 2014, respectively. On April 30, 2015, Oprah Winfrey agreed to extend her exclusivity agreement with OWN and thenote receivable agreement was modified to reduce its interest rate, compounded annually, from 7.5% to 5.0%, retroactive to January 1, 2014. During 2015,the Company received net repayments of $82 million from OWN, accrued interest on the note receivable of $23 million and reduced the note receivable by$14 million for the change in interest rate. During 2014, the Company received net repayments of $56 million from OWN and accrued interest on the notereceivable of $33 million.The note receivable is secured by the net assets of OWN. While the Company has no further funding commitments, the Company will provideadditional funding to OWN, if necessary, and expects to recoup amounts funded. There can be no event of default on the borrowing until 2023. However,borrowings are scheduled for repayment four years after the borrowing date to the extent that OWN has excess cash to repay the borrowings then due.Following such repayment, OWN’s subsequent cash distributions will be shared equally between the Company and Harpo. OWN began repaying amountsowed to the Company during 2013.In accordance with the venture agreement, losses generated by OWN are allocated to both investors based on their proportionate ownership interests.However, the Company has recorded its portion of OWN’s losses based upon accounting policies for equity method investments. Prior to the contribution ofthe Discovery Health network to OWN at its launch, the Company had recognized $104 million, or 100%, of OWN’s net losses. During the three monthsended March 31, 2012, accumulated operating losses at OWN exceeded the equity contributed to OWN, and Discovery began again to record 100% ofOWN’s net losses. Although OWN has become profitable, the Company will record 100% of any net losses to the extent they occur resulting from OWN'soperations as long as Discovery has provided all funding to OWN and OWN’s accumulated losses continue to exceed the equity contributed. All of OWN'snet income has been and will continue to be recorded by the Company until the Company recovers losses absorbed in excess of the Company's equityownership interest.The carrying value of the Company’s investment in OWN of $373 million and $424 million as of December 31, 2015 and December 31, 2014,respectively, includes the Company's note receivable and accumulated investment losses. The Company monitors the financial results of OWN along withother relevant business information to assess the recoverability of the OWN note receivable. There has been no impairment of the OWN note receivable.Harpo has the right to require the Company to purchase all or part of Harpo’s interest in OWN at fair market value up to a maximum put amount duringa 90-day window every two and a half years commencing January 1, 2016. The maximum put amount ranges from $100 million on the first put exercise dateup to a cumulative cap of $400 million on the fifth put exercise date. The Company has not recorded amounts for the put right because the fair value of thisput right was zero as of December 31, 2015 and December 31, 2014.Other Equity Method InvestmentsOn September 23, 2014, the Company acquired a 50% equity method ownership interest in All3Media, a production studio company, for a cashpayment of £90 million ($147 million) and with an enterprise value of £556 million ($912 million). All3Media recapitalized its debt structure to effect thetransaction. All3Media is not a VIE.On March 31, 2015 and May 30, 2014, the Company acquired from TF1 a controlling interest in each of its Eurosport France and EurosportInternational equity method investments, respectively, by increasing its ownership stake from 20% to 51%. As a result, the Company changed its accountingfor Eurosport France and Eurosport International from equity method investments to consolidated subsidiaries as of their respective acquisition dates. (SeeNote 3.) On October 1, 2015, the Company acquired the remaining 49% of Eurosport upon TF1's exercise of its right to put. (See Note 11.)On September 23, 2014, the Company acquired an additional 10% ownership interest in Discovery Family and obtained a controlling financial interest.The purchase increased the Company's interest from 50% to 60%. As a result, the Company changed its accounting for Discovery Family from an equitymethod investment to a consolidated subsidiary. (See Note 3.)Available-for-Sale SecuritiesOn November 12, 2015, the Company acquired 5 million shares, or 3.4%, of Lions Gate Entertainment Corp. ("Lionsgate"), an entertainment company, for$195 million. Lionsgate operates in the motion picture production and distribution, television programming and syndication, home entertainment, familyentertainment and digital distribution businesses. As the shares have a readily determinable fair value and the Company has the intent to retain theinvestment, the shares are classified as available-for-sale ("AFS") securities.82DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSIn connection with this transaction, the Company hedged 50% of the shares with an equity collar (the “Lionsgate Collar”). When the share price of Lionsgateis within the boundaries of the collar, the Company records the gains or losses on the Lionsgate AFS securities as a component of other comprehensive (loss)income. When the share price of the Lionsgate AFS is outside the boundaries of the collar, the Company records the gain or loss for the change in the fairvalue of the hedged portion of Lionsgate that is outside the boundaries of the collar as a component of other (expense) income to offset to the gain/ loss fromthe change in intrinsic value of the associated fair value hedge. For the year ended December 31, 2015, the Company recorded a temporary unrealized loss of$33 million related to this investment, of which $31 million was recorded as a component of other comprehensive (loss) income and $2 million was recordedas a component of other (expense) income. The Company has pledged to the derivative counterparty 2.5 million shares as collateral for the Lionsgate Collarthrough the maturity dates of the Lionsgate Collar; the counterparty to the Lionsgate Collar has the right to re-use all of the pledged shares and collectdividends. (See Note 10.)The components of the Company's available-for-sale investments, which are included in other non-current assets, are summarized in the table below.

The Company's cost method investments as of December 31, 2014 primarily included an educational website.83DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSNOTE 5. FAIR VALUE MEASUREMENTSFair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between marketparticipants. Assets and liabilities carried at fair value are classified in the following three categories: Level 1–Quoted prices for identical instruments in active markets.Level 2–Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments inmarkets that are not active; and model-derived valuations in which all significant inputs and significantvalue drivers are observable in active markets.Level 3–Valuations derived from techniques in which one or more significant inputs are unobservable.The table below presents assets and liabilities measured at fair value on a recurring basis (in millions).

The fair value of Level 1 trading securities was determined by reference to the quoted market price per unit in active markets multipliedby the number of units held without consideration of transaction costs. The fair value of the related deferred compensation plan liability was determinedbased on the fair value of the related investments elected by employees.Available-for-sale securities represent equity investments in highly liquid instruments. The fair value of Level 1 available-for-sale securities wasdetermined by reference to the quoted market price per unit in active markets multiplied by the number of units held without consideration of transactioncosts. (See Note 4).Derivative financial instruments are comprised of foreign exchange contracts used by the Company to modify exposure to market risks from foreignexchange, interest rate contracts used to modify exposure to market risks from interest rates for forecasted issuances of debt and fair value hedges to modifyexposure to AFS securities. (See Note 10.) The fair value of Level 2 derivative financial instruments was determined using a market-based approach. As ofDecember 31, 2014, TF1 had the conditional right to require the Company to purchase its remaining shares in Eurosport France at various dates shouldDiscovery complete its planned acquisition of a controlling interest in Eurosport France. The fair value measurement was determined through the use of aMonte Carlo simulation model. The Monte Carlo model simulates the various sources of uncertainty impacting the value of a financial instrument and usesthose simulations to develop an estimated fair value for the instrument. The valuation methodology for the TF1 put for Eurosport France was based onunobservable estimates and judgments, and therefore represented a Level 3 fair value measurement. (See Note 3.)In addition to the financial instruments listed in the tables above, the Company has other financial instruments, including cash deposits, accountsreceivable, accounts payable, commercial paper, borrowings under the revolving credit facility, capital leases and senior notes. The carrying values for suchfinancial instruments, other than senior notes, each approximated their fair values as of December 31, 2015 and December 31, 2014. The estimated fair valueof the Company’s outstanding senior notes using quoted prices from over the counter markets, considered Level 2 inputs, was $6.6 billion and $7.2 billion asof December 31, 2015 and 2014, respectively.NOTE 6.

Thisassessment included, but was not limited to, consideration of the results of the Company's most recent quantitative impairment test, macroeconomicconditions, industry and market conditions, cost factors, cash flows, changes in key personnel and the Company's share price. Based on this assessment, theCompany determined that it was more likely than not that the fair value of those reporting units exceeded their carrying values. Therefore, no goodwillimpairment was recorded during 2015. The Company performed a quantitative goodwill impairment assessment for the remaining three reporting units. Theestimated fair value of each reporting unit exceeded its carrying value and, therefore, no impairment was recorded. The fair values of the reporting units weredetermined using a combination of DCF and market-based valuation models. Cash flows were determined based on Company estimates of future operatingresults and discounted using an internal rate of return based on an assessment of the risk inherent in future cash flows of the respective reporting unit.During the fourth quarter of 2014, the Company performed a qualitative goodwill impairment assessment for all reporting units, and determined that itwas more likely than not that the fair value of those reporting units exceeded their carrying values.During the fourth quarter of 2013, the Company performed a quantitative goodwill impairment assessment for all reporting units. Due to the period oftime elapsed since the last quantitative impairment test in 2010, the Company elected to proceed to the first step of the quantitative goodwill impairment testfor all reporting units. The estimated fair value of each reporting unit exceeded its carrying value and, therefore, no impairment was recorded. The fair valuesof the reporting units were determined using DCF and market-based valuation models. The market-based valuation models utilized multiples of earningsbefore interest, taxes, depreciation and amortization (“EBITDA”). Both the DCF and market-based models resulted in substantially similar fair values. Cashflows were determined based on Company estimates of future operating results and discounted using an internal rate of return based on an assessment of therisk inherent in future cash flows of the respective reporting unit.88DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSNOTE 9.

In contemplation of the issuance of the 2015 USD Notes, the Company terminated and settled allinterest rate forward contracts with its counterparties, which were designated as cash flow hedges used to hedge the pricing of the 2015 USD Notes. (See Note10.)DCL has the option to redeem some or all of the senior notes at any time prior to their maturity by paying a make-whole premium, if the redemptiondate is prior to three months from the maturity date or by paying their principal amount on or after such date, plus, in each case, accrued and unpaid interest,if any, through the date of repurchase. All of DCL's outstanding senior notes are fully and unconditionally guaranteed on an unsecured and unsubordinatedbasis by Discovery and contain certain nonfinancial covenants, events of default and other customary provisions. The Company and DCL were incompliance with all covenants and customary provisions under DCL's outstanding senior notes, and there were no events of default as of December 31, 2015.On March 31, 2015, the Company redeemed $850 million aggregate principal amount of its 3.70% senior notes that had an original maturity of June 1,2015. The repayment included a payment of $1 million for the original issue discount on the 3.70% senior notes and resulted in a pretax loss onextinguishment of debt of $5 million for make-whole premiums.

Borrowing capacity under this agreement is reduced by the outstanding borrowings under the commercial paperprogram discussed below. DCL also had the ability to request an increase of the revolving credit facility up to an aggregate additional $1.0 billion, upon thesatisfaction of certain conditions. As of December 31, 2015, the revolving credit facility agreement provided for a maturity date of June 20, 2019. In February2016, the Company amended and restated the revolving credit facility to extend DCL's borrowing capacity up to $2.0 billion, to eliminate the multi-currencyborrowing sublimit, to extend the maturity date to February 4, 2021 and to provide the option to request up to two additional 364-day renewal periods.As of December 31, 2015, the Company had outstanding borrowings under the revolving credit facility of $782 million at a weighted average interestrate of 1.55%, of which $207 million was denominated in foreign currencies. As of December 31, 2014, the Company had outstanding borrowings under therevolving credit facility of $38 million at a weighted average interest rate of 1.98%. The interest rate on borrowings under the revolving credit facility isvariable based on DCL's then-current credit ratings for its publicly traded debt and changes in financial index rates. For dollar-denominated borrowings, theinterest rate is based, at the Company's option, on either adjusted LIBOR plus a margin, or an alternate base rate plus a margin. For borrowings denominatedin foreign currencies, the interest rate is based on adjusted LIBOR, plus a margin. The current margins are 1.10% and 0.10%, respectively, per annum foradjusted LIBOR and alternate base rate borrowings. A monthly facility fee is charged based on the total capacity of the facility, and interest is charged basedon the amount borrowed on the facility. The current facility fee rate is 0.15% per annum and subject to change based on DCL's then-current credit ratings. Allobligations of DCL and the other borrowers under the revolving credit facility are unsecured and are fully and unconditionally guaranteed by Discovery.The credit agreement governing the revolving credit facility contains customary representations, warranties and events of default, as well as affirmativeand negative covenants.

The Company does not enter into or hold derivative financial instruments for speculativetrading purposes.The Company designates foreign currency forward contracts as cash flow hedges to mitigate foreign currency risk arising from third-party revenue andinter-company licensing agreements. The Company also designates interest rate contracts used to hedge the pricing for certain senior notes as cash flowhedges. Gains and losses on the effective portion of designated cash flow hedges are initially recorded in accumulated other comprehensive loss on theconsolidated balance sheets and reclassified into the statements of operations in the same line item in which the hedged item is recorded in the same period asthe hedged item affects earnings. If it becomes probable that a forecasted transaction will not occur, any related gains and losses recorded in accumulatedother comprehensive loss on the consolidated balance sheets are reclassified to other (expense) income, net on the consolidated statements of operations inthat period.90DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSDuring the three months ended March 31, 2015, the Company terminated and settled its interest rate cash flow hedges following the pricing of the 2015USD Notes. The total notional value of the interest rate forward contracts at the termination date was $490 million, which exceeded the $300 millionprincipal amount of the 2015 USD Notes. (See Note 9.) Of the $40 million pretax loss recorded in accumulated other comprehensive loss at the terminationdate, $29 million was an effective cash flow hedge that will be amortized as an adjustment to interest expense over the ten year term of the 2015 USD Notesconsistent with amortization of the debt discount. The remaining hedge ineffectiveness of $11 million was reclassified into other (expense) income, net onthe consolidated statements of operations during the three months ended March 31, 2015, because the forecasted borrowing transaction was no longerprobable.The Company designates derivative instruments used to mitigate the risk of changes in the fair value of its AFS investments as fair value hedges. OnNovember 12, 2015 the Company entered into the Lionsgate Collar, designed to mitigate the risk of market fluctuations with respect to 50% of the Lionsgateshares held by the Company. (See Note 4.) The collar, which qualifies for hedge accounting, settles in three tranches starting in 2019 and ending in 2022.Gains and losses from the Lionsgate Collar, including any ineffective portion and amounts excluded from the assessment of effectiveness, and the offsettingchanges in fair value of the AFS investment outside the boundaries of the collar are recorded in other (expense) income, net on the consolidated statement ofoperations.The Company may also enter into derivative instruments that are not designated as hedges and do not qualify for hedge accounting. During the threemonths ended September 30, 2015, the Company entered into foreign exchange forward contracts and a zero-cost collar in connection with the purchase ofTF1's mandatorily redeemable noncontrolling interest in Eurosport that closed on October 1, 2015. (See Note 11.) These derivatives, which economicallyhedged the Company's exposure to fluctuations in foreign currency exchange rates, did not qualify for hedge accounting. Realized and unrealized gains andlosses on contracts that do not qualify for hedge accounting are reflected in other (expense) income, net on the consolidated statements of operations.The Company records all unsettled derivative contracts at their gross fair values on the consolidated balance sheets. (See Note 5.) There were noamounts eligible to be offset under master netting agreements as of December 31, 2015 and December 31, 2014.The cash flows from the effective portion of derivative instruments used as hedges are classified in the consolidated statements of cash flows in the samesection as the cash flows from the hedged item. For example, the cash paid to settle the effective portion of interest rate derivatives intended to hedge thepricing of the 2015 USD Notes during the year ended December 31, 2015 is reported as a financing activity in the consolidated statements of cash flowsconsistent with the classification of cash proceeds from borrowings of debt, net of discount. The cash flows from the ineffective portion of derivativeinstruments used as hedges and derivative contracts not designated as hedges are reported as investing activities in the consolidated statements of cash flows.The following table summarizes the notional amount and fair value of the Company's derivative positions (in millions).

REDEEMABLE NONCONTROLLING INTERESTSRedeemable noncontrolling interests reflected as of the balance sheet date are the greater of the noncontrolling interest balances adjusted forcomprehensive income items and distributions or the redemption values remeasured at the period end foreign exchange rates (i.e., the "floor"). Adjustments tothe carrying amount of redeemable noncontrolling interests to redemption value as a result of changes in exchange rates are reflected in currency translationadjustments, a component of other comprehensive (loss) income; however, such currency translation adjustments to redemption value are allocated toDiscovery stockholders only. Redeemable noncontrolling interest adjustments of redemption value to the floor are reflected in retained earnings.

On July 22, 2015, TF1 exercised itsright to put the entirety of its remaining 49% noncontrolling interest in Eurosport to the Company for €491 million ($551 million as of the date redemptionbecame mandatory, and $548 million on October 1, 2015 when the transaction closed). The difference between the carrying amount of the redeemablenoncontrolling interest and its fair value at the date of exercise resulted in a €25 million ($28 million) adjustment to retained earnings, recognized as acomponent of redeemable noncontrolling interest adjustments to redemption value on the consolidated statements of equity. Upon acquisition of TF1'snoncontrolling interest, the Company adjusted the accumulated other comprehensive income balance of $61 million attributable to TF1 and allocated it toDiscovery stockholders.In connection with the acquisition of a controlling interest in Discovery Family on September 23, 2014, the Company recognized $238 million forHasbro's redeemable noncontrolling interest in Discovery Family. Hasbro has the right to put the entirety of its remaining 40% non-controlling interest to theCompany for one year after December 31, 2021, or in the event a Discovery performance obligation related to Discovery Family is not met. Embedded in theredeemable noncontrolling interest is also a Discovery call right that is exercisable for one year after December 31, 2021. Upon the exercise of the put or calloptions, the price to be paid for the redeemable noncontrolling interest is a function of the then-current fair market value of the redeemable noncontrollinginterest, to which certain discounts and floor values may apply in specified situations depending upon the party exercising the put or call and the basis forthe exercise of the put or call. As Hasbro's put right is outside the control of the Company, Hasbro's 40% noncontrolling interest is presented as redeemablenoncontrolling interest outside of permanent equity on the Company's consolidated balance sheet.In connection with the acquisition of SBS Nordic on April 9, 2013, the Company recognized $6 million redeemable noncontrolling interest for the fairvalue of a noncontrolling interest in one of its Danish subsidiaries. On November 19, 2014, the Company purchased the noncontrolling interest for $1million. The difference between the consideration transferred and the recorded value of the previous redeemable noncontrolling interest was recorded toadditional paid-in capital.In connection with the acquisition of a controlling interest in Discovery Japan on January 10, 2013, J:COM obtained the right to put all, but not lessthan all, of its 20% noncontrolling interest to Discovery at any time for cash.

PRSUs represent the contingent right to receive shares of the Company’s Series Aand C common stock, substantially all of which vest over three to four years based on continuous service and whether the Company achieves certainoperating performance targets. The performance targets for substantially all PRSUs are cumulative measures of the Company’s adjusted operating incomebefore depreciation and amortization (as defined in Note 21), free cash flows and revenues over a three year period. The number of PRSUs that vestprincipally range from 0% to 100% based on a sliding scale where achieving or exceeding the performance target will result in 100% of the PRSUs vestingand achieving less than 80% of the target will result in no portion of the PRSUs vesting. Additionally, for certain PRSUs the Company’s CompensationCommittee has discretion in determining the final amount of100DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSunits that vest, but may not increase the amount of any PRSU award above 100%. Upon vesting, each PRSU becomes convertible into one share of theCompany’s Series A or Series C common stock as applicable. Holders of PRSUs do not receive payments of dividends in the event the Company pays a cashdividend until such PRSUs are converted into shares of the Company’s common stock.The Company records compensation expense for PRSUs ratably over the graded vesting service period once it is probable that the performance targetswill be achieved. In any period in which the Company determines that achievement of the performance targets is not probable, the Company ceases recordingcompensation expense and all previously recognized compensation expense for the award is reversed.Compensation expense is separately recorded for each vesting tranche of PRSUs for a particular grant. For certain PRSUs, the Company measures thefair value and related compensation cost based on the closing price of the Company’s Series A or C common stock on the grant date. For PRSUs for which theCompany’s Compensation Committee has discretion in determining the final amount of units that vest or in situations where the executive is able towithhold taxes in excess of the minimum statutory requirement, compensation cost is remeasured at each reporting date based on the closing price of theCompany’s Series A or Series C common stock.As of December 31, 2015, unrecognized compensation cost, net of expected forfeitures, related to PRSUs was $28 million, which is expected to berecognized over a weighted-average period of 1.1 years based on the Company’s current assessment of the PRSUs that will vest, which may differ from actualresults.SARsThe table below presents SAR award activity (in millions, except years and weighted-average grant price).

Cash-settled SARs entitle the holder to receive a cash payment for the amount bywhich the price of the Company’s Series A or Series C common stock exceeds the base price established on the grant date. Cash-settled SARs are granted witha base price equal to or greater than the closing market price of the Company’s Series A or Series C common stock on the date of grant. Stock-settled SARsentitle the holder to shares of Series A or Series C common stock in accordance with the award agreement terms.The fair value of outstanding SARs is estimated using the Black-Scholes option-pricing model. The weighted-average assumptions used to determinethe fair value of outstanding SARs were as follows.

The Company made cashpayments of $11 million, $29 million and $11 million to settle exercised SARs during 2015, 2014 and 2013, respectively. As of December 31, 2015, therewas $4 million of unrecognized compensation cost, net of estimated forfeitures, related to SARs, which is expected to be recognized over a weighted-averageperiod of 0.9 years.101DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSUnit AwardsUnit awards represent the contingent right to receive a cash payment for the amount by which the vesting price exceeds the grant price. Because unitawards are cash-settled, the Company remeasures the fair value and compensation expense of outstanding unit awards each reporting date until settlement.During the year ended December 31, 2015, the Company made cash payments of $14 million to settle all 1.2 million remaining unit awards, which had aweighted-average grant price of $20.59.Employee Stock Purchase PlanThe DESPP enables eligible employees to purchase shares of the Company’s common stock through payroll deductions or other permitted means.Unless otherwise determined by the Company’s Compensation Committee, the purchase price for shares offered under the DESPP is 85% of the closing priceof the Company’s Series A common stock on the purchase date. The Company recognizes the fair value of the discount associated with shares purchased inselling, general and administrative expense on the consolidated statement of operations. The Company’s Board of Directors has authorized 9 million sharesof the Company’s common stock to be issued under the DESPP. During the years ended December 31, 2015, 2014 and 2013 the Company issued 208thousand, 191 thousand and 141 thousand shares under the DESPP, respectively, and received cash totaling $5 million, $6 million and $5 million,respectively.NOTE 14. RETIREMENT SAVINGS PLANSThe Company has defined contribution and other savings plans for the benefit of its employees that meet eligibility requirements. Eligible employeesmay contribute a portion of their compensation to the plans, which may be subject to certain statutory limitations. For these plans, the Company also makescontributions including discretionary contributions, subject to plan provisions, which vest immediately. The Company made total contributions of $36million, $33 million and $28 million during 2015, 2014 and 2013, respectively. The Company's contributions were recorded in selling, general andadministrative expense in the consolidated statements of operations.The Company’s savings plans include a deferred compensation plan through which members of the Company’s executive team in the U.S. may elect todefer up to 50% of their eligible compensation. The amounts deferred are invested in various mutual funds at the direction of the executive, which are used tofinance payment of the deferred compensation obligation. Distributions from the deferred compensation plan are made upon termination or other events asspecified in the plan. The Company has established a separate trust to hold the investments that finance the deferred compensation obligation. The accountsof the separate trust are included in the Company’s consolidated financial statements. The investments are included in prepaid expenses and other currentassets and the deferred compensation obligation is included in accrued liabilities in the consolidated balance sheets. The values of the investments anddeferred compensation obligation are recorded at fair value. Changes in the fair value of the investments are offset by changes in the fair value of the deferredcompensation obligation. (See Note 5.)NOTE 15.

For the year ended December 31, 2015, increases in unrecognized tax benefits related to the uncertainty of allocation andtaxation of income among multiple jurisdictions was offset by the movements of tax positions as a result of multiple audit resolutions and lapse of statutes oflimitations.The Company and its subsidiaries file income tax returns in the U.S. and various state and foreign jurisdictions. The Company is currently underexamination by the IRS for its 2009 and 2012 to 2014 consolidated federal income tax returns. The Company does not anticipate any material adjustments.With few exceptions, the Company is no longer subject to audit by any jurisdiction for years prior to 2006. Adjustments that arose from the completion ofaudits for certain tax years have been included in the change in uncertain tax positions in the Company's effective tax rate reconciliation table above.It is reasonably possible that the total amount of unrecognized tax benefits related to certain of the Company's uncertain tax positions could decreaseby as much as $76 million within the next twelve months as a result of ongoing audits, lapses of statutes of limitations or regulatory developments.As of December 31, 2015, 2014 and 2013, the Company had accrued approximately $20 million, $17 million and $11 million, respectively, of totalinterest and penalties payable related to unrecognized tax benefits. The Company recognizes interest and penalties related to unrecognized tax benefits as acomponent of income tax expense.NOTE 17.

Leases are not cancelableprior to their expiration.Content purchase commitments are associated with third-party producers and sports associations for content that airs on the television networks.Production contracts generally require: purchase of a specified number of episodes; payments over the term of the license; and include both programs thathave been delivered and are available for airing and programs that have not yet been produced or sporting events that have not yet taken place. If the contentis ultimately never produced, the Company's commitments expire without obligation. The commitments disclosed above exclude content liabilitiesrecognized on the consolidated balance sheet.Other purchase obligations include agreements with certain vendors and suppliers for the purchase of goods and services whereby the underlyingagreements are enforceable, legally binding and specify all significant terms. Significant purchase obligations include transmission services, television ratingservices, marketing research, employment contracts, equipment purchases, and information technology and other services. Some of these contracts do notrequire the purchase of fixed or minimum quantities and generally may be terminated with a 30-day to 60-day advance notice without penalty, and are notincluded in the table above past the 30-day to 60-day advance notice period. Amounts related to employment contracts include base compensation and donot include compensation contingent on future events.Although the Company had limited funding commitments to equity method investees as of December 31, 2015, the Company may provideuncommitted additional funding to its equity method investments in the future.

(See Note 11.)Legal MattersThe Company is party to various other lawsuits and claims in the ordinary course of business, including claims related to employees, vendors, otherbusiness partners or patent issues. However, a determination as to the amount of the accrual required for such contingencies is highly subjective and requiresjudgment about future events. Although the outcome of these matters cannot be predicted with certainty and the impact of the final resolution of thesematters on the Company's results of operations in a111DISCOVERY COMMUNICATIONS, INC.NOTES TO CONSOLIDATED FINANCIAL STATEMENTSparticular subsequent reporting period is not known, management does not believe that the resolution of these other matters will have a material adverseeffect on the Company's consolidated financial position, future results of operations or cash flows.GuaranteesThere were no guarantees recorded as of December 31, 2015 and December 31, 2014.The Company may provide or receive indemnities intended to allocate business transaction risks.

Inter-segment transactions primarily include the purchase of advertising and content betweensegments.The Company evaluates the operating performance of its segments based on financial measures such as revenues and adjusted operating income beforedepreciation and amortization (“Adjusted OIBDA”). Adjusted OIBDA is defined as operating income excluding: (i) mark-to-market equity-basedcompensation, (ii) depreciation and amortization, (iii) amortization of deferred launch incentives, (iv) restructuring and other charges, (v) certain impairmentcharges, (vi) gains and losses on business and asset dispositions, and (vii) certain inter-segment eliminations related to production studios. The Companyuses this measure to assess the operating results and performance of its segments, perform analytical comparisons, identify strategies to improve performanceand allocate resources to each segment. The Company believes Adjusted OIBDA is relevant to investors because it allows them to analyze the operatingperformance of each segment using the same metric management uses. The Company excludes mark-to-market equity-based compensation, restructuring andother charges, certain impairment charges, and gains and losses on business and asset dispositions from the calculation of Adjusted OIBDA due to theirvolatility. The Company also excludes depreciation of fixed assets, amortization of intangible assets and deferred launch incentives, as these amounts do notrepresent cash payments in the current reporting period. Certain corporate expenses are excluded from segment results to enable executive management toevaluate segment performance based upon the decisions of segment executives. Adjusted OIBDA should be considered in addition to, but not a substitute for,operating income, net income and other measures of financial performance reported in accordance with GAAP.
