Business and Basis of Presentation	12 Months Ended
	Dec. 31, 2015
Basis of Presentation	Note 1: Business and Basis of Presentation We are a global media and technology company with two primary businesses, Comcast Cable and NBCUniversal.

Accounting Policies

Accounting Policies	12 Months Ended
	Dec. 31, 2015
Accounting Policies	Note 2: Accounting Policies Our consolidated financial statements are prepared in accordance with GAAP, which requires us to select accounting policies, including in certain cases industry-specific policies, and make estimates that affect the reported amount of assets, liabilities, revenue and expenses, and the related disclosure of contingent assets and contingent liabilities. Actual results could differ from these estimates. We believe that the judgments and related estimates for the followin g items are critical in the preparation of our consolidated financial statements: valuation and impairment testing of cable franchise rights (see Note 9) film and television costs (see Note 6) In addition, the following accounting policies are specific to the industries in which we operate: capitalization and amortization of film and television costs (see Note 6) installation revenue and costs for connecting customers to our cable systems (see revenue recognition below and Note 8) In formation on our other accounting policies and methods that are used in the preparation of our consolidated financial statements are included, where applicable, in their respective footnotes that follow. Below is a discussion of accounting policies and met hods used in our consolidated financial statements that are not presented within other footnotes. Revenue Recognition Cable Communications Segment Our Cable Communications segment generates revenue primarily from subscriptions to our video, high-speed Inte rnet and voice services (“cable services”) and from the sale of advertising. We recognize revenue from cable services as each service is provided. Customers are typically billed in advance on a monthly basis based on the services and features they receive and the type of equipment they use. Since installation revenue obtained from the connection of customers to our cable systems is less than the related direct selling costs, we recognize revenue as connections are completed. We manage credit risk by screeni ng applicants through the use of internal customer information, identification verification tools and credit bureau data. If a customer’s account is delinquent, various measures are used to collect outstanding amounts, including termination of the customer ’s cable services. As part of our distribution agreements with cable networks, we generally receive an allocation of scheduled advertising time on cable networks that our Spotlight business sells to local, regional and national advertisers. We recognize a dvertising revenue when the advertising is aired or viewed. In most cases, the available advertising units are sold by our sales force. In some cases, we work with representation firms as an extension of our sales force to sell a portion of the advertising units allocated to us. We also represent the advertising sales efforts of other multichannel video providers in some markets. Since we are acting as the principal in these arrangements, we record the advertising that is sold in revenue and the fees paid t o representation firms and multichannel video providers in other operating and administrative expenses. Revenue earned from other sources, such as our home security and automation services, is recognized when services are provided or events occur. Under the terms of our cable franchise agreements, we are generally required to pay to the cable franchising authority an amount based on our gross video revenue. We normally pass these fees through to our cable services customers and classify the fees as a comp onent of revenue with the corresponding costs included in other operating and administrative expenses. Cable Networks and Broadcast Television Segments Our Cable Networks segment generates revenue primarily from the distribution of our cable network progra mming to multichannel video providers, from the sale of advertising on our cable networks and related digital media properties, from the licensing of our owned programming through various distribution platforms, from the sale of our owned programming throu gh digital distribution services such as iTunes, and from the programming our cable production studio sells to third-party networks and subscription video on demand services. Our Broadcast Television segment generates revenue primarily from the sale of adv ertising on our broadcast networks, owned local broadcast television stations and related digital media properties, from the licensing of our owned programming through various distribution platforms, including to cable and broadcast networks, from the fees received under retransmission consent agreements and from the programming our broadcast television production studio sells to third-party networks and subscription video on demand services. We recognize revenue from distributors as programming is provided , generally under multiyear distribution agreements. From time to time, the distribution agreements expire while programming continues to be provided to the distributor based on interim arrangements while the parties negotiate new contract terms. Revenue r ecognition is generally limited to current payments being made by the distributor, typically under the prior contract terms, until a new contract is negotiated, sometimes with effective dates that affect prior periods. Differences between actual amounts de termined upon resolution of negotiations and amounts recorded during these interim arrangements are recorded in the period of resolution. Advertising revenue for our Cable Networks and Broadcast Television segments is recognized in the period in which comm ercials are aired or viewed. In some instances, we guarantee audience ratings for the commercials. To the extent there is a shortfall in the ratings that were guaranteed, a portion of the revenue is deferred until the shortfall is settled, primarily by pro viding additional advertising units. We recognize revenue from the licensing of our owned programming and programming produced by our studios for third parties when the content is available for use by the licensee, and when certain other conditions are met . When license fees include advertising time, we recognize the component of revenue associated with the advertisements when they are aired or viewed. Filmed Entertainment Segment Our Filmed Entertainment segment generates revenue primarily from the worldwide distribution of our produced and acquired films for exhibition in movie theaters, from the licensing of our owned and acquired films through various distribution platforms, and from the sale of our owned and acquired films on standard-definition video discs and Blu-ray discs (together, “DVDs”) and through digital distribution services. Our Filmed Entertainment segment also generates revenue from producing and licensing live stage plays, from the distribution of filmed entertainment produced by thi rd parties, and from Fandango, our movie ticketing and entertainment business. We recognize revenue from the distribution of films to movie theaters when the films are exhibited. We recognize revenue from the licensing of a film when the film is available for use by the licensee, and when certain other conditions are met. We recognize revenue from DVD sales, net of estimated returns and customer incentives, on the date that DVDs are delivered to and made available for sale by retailers. Theme Parks Segment Our Theme Parks segment generates revenue primarily from ticket sales and guest spending at our Universal theme parks in Orlando, Florida; Hollywood, California; and, as of November 2015, Osaka, Japan, as well as from licensing and other fees. We recogni ze revenue from advance theme park ticket sales when the tickets are used. For annual passes, we recognize revenue on a straight-line basis over the period following the activation date. Cable Communications Programming Expenses Cable Commu nications programming expenses are the fees we pay to license the programming we distribute to our video customers. Programming is generally acquired under multiyear distribution agreements, with rates typically based on the number of customers that receiv e the programming, channel positioning and the extent of distribution. From time to time, these contracts expire and programming continues to be provided under interim arrangements while the parties negotiate new contract terms, sometimes with effective da tes that affect prior periods. While payments are typically made under the prior contract’s terms, the amount of programming expenses recorded during these interim arrangements is based on our estimates of the ultimate contract terms expected to be negotia ted. Differences between actual amounts determined upon resolution of negotiations and amounts recorded during these interim arrangements are recorded in the period of resolution. When our Cable Communications segment receives incentives from cable networ ks for the licensing of their programming, we defer a portion of these incentives, which are included in other current and noncurrent liabilities, and recognize them over the term of the contract as a reduction to programming expenses. Advertising Expense s Advertising costs are expensed as incurred. Cash Equivalents The carrying amounts of our cash equivalents approximate their fair values. Our cash equivalents consist primarily of money market funds and U.S. government obligations, as well as commercial paper and certificates of deposit with maturities of three months or less when purchased. Derivative Financial Instruments We use derivative financial instruments to manage our exposure to the risks associated with fluctuations in interest rates, foreign e xchange rates and equity prices. Our objective is to manage the financial and operational exposure arising from these risks by offsetting gains and losses on the underlying exposures with gains and losses on the derivatives used to economically hedge them. Our derivative financial instruments are recorded in our consolidated balance sheet at fair value. The impact of our derivative financial instruments on our consolidated financial statements was not material for all periods presented. Asset Retirement Ob ligations Certain of our cable franchise agreements and lease agreements contain provisions requiring us to restore facilities or remove property in the event that the franchise or lease agreement is not renewed. We expect to continually renew our cable fr anchise agreements and therefore cannot reasonably estimate any liabilities associated with such agreements. A remote possibility exists that franchise agreements could be terminated unexpectedly, which could result in us incurring significant expense in c omplying with restoration or removal provisions. We do not have any significant liabilities related to asset retirements recorded in our consolidated financial statements

Recent Accounting Pronouncement

Recent Accounting Pronouncements	12 Months Ended
	Dec. 31, 2015
Recent Accounting Pronouncements	Note 3: Recent Accounting Pronouncements Revenue Recognition In May 2014, the Financial Accounting Standards Board (“ FASB ”) updated the accounting guidance related to revenue re cognition. The updated accounting guidance provides a single, contract-based revenue recognition model to help improve financial reporting by providing clearer guidance on when an entity should recognize revenue, and by reducing the number of standards to which an entity has to refer. In July 2015, the FASB voted to defer the effective date by one year to December 15, 2017 for annual reporting periods beginning after that date. The updated accounting guidance provides companies with alternative methods of a doption . We are currently in the process of determining the impact that the updated accounting guidance will have on our consolidated financial statements and our method of adoption. Consolidations In February 2015, the FASB updated the accounting guidance related to consolidation under the variable interest entity and voting interest entity models. The updated accounting guidance modifies the consolidation guidance for VIEs, limited partnerships and similar legal entities. The updated guidance is effective for us as of January 1, 2016. The updated accounting guidance provides companies with alternative methods of adoption. We do not expect t he updated accounting guidance to have a material impact on our consolidated financial statements. Debt Issuance Costs In April 2015, the FASB updated the accounting guidance related to the balance sheet presentation of debt issuance costs. The updated accounting guidance requires that debt issuance costs be presented as a direct deduction from the associated debt obligation. We ha ve adopted this guidance as of December 31, 2015 and as a result we have reclassified unamortized debt issuance costs of $153 million as of December 31, 2014 from other noncurrent assets to a reduction of long-term debt on our consolidated balance sheet. A s of December 31, 2015 , unamortized debt issuance costs included in long-term debt was $176 million. Deferred Income Taxes In November 2015, the FASB updated the accounting guidance related to the balance sheet presentation of deferred taxes. The upda ted accounting guidance requires that all deferred tax liabilities and assets be classified as noncurrent in a classified balance sheet. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and p resented as a single amount is not affected by the amendments in this update. We have adopted this guidance prospectively as of December 31, 2015. Therefore, prior periods have not been adjusted to reflect this adoption. If we had retrospectively adopted t his guidance, $195 million of current deferred tax assets would have been reclassified from current assets to long-term liabilities as of December 31, 2014.

Significant Transactions

Significant Transactions	Note 5: Significant Transactions 2015 Universal Studios Japan O n November 13, 2015, NBCUniversal acquire d a 51% economic interest in Universal Studios Japan for $1.5 billion. The acquisition was funded through cash on hand and borrowings under our commercial paper program. Universal Studios Japan is a VIE based on the governance structure and we consolidate Universal Studios Japan as we have the power to direct activities that most significantly impact its economic performance. There are no liquidi ty arrangements, guarantees, or other financial commitments between us and Universal Studios Japan, and therefore our maximum risk of financial loss is NBCUniversal’s 51% interest. Universal Studios Japan’s results of operations are reported in our Theme P arks segment following the acquisition date. Preliminary Allocation of Purchase Price Due to the limited amount of time since the date of acquisition, the assets and liabilities of Universal Studios Japan were recorded at their historical carrying value. We will adjust these amounts to fair value as valuations are completed and we obtain information necessary to complete the analyses, but no later than one year from the acquisition date. The 49% noncontrolling interest in Universal Studios Japan is recorde d in the equity section of our consolidated financial statements and has been recorded based on the total value of Universal Studios Japan implied in the transaction. For purposes of this preliminary allocation, the excess of the total value implied in the transaction over the historical carrying value has b een recorded as goodwill. The table below presents the preliminary allocation of the purchase price to the assets and liabilities of Universal Studios Japan. Preliminary Allocation of Purchase Price (in millions) Property and equipment (see Note 8) $ 642 Intangible assets (see Note 9) 57 Working capital (24) Debt (see Note 10) (3,271) Other noncurrent assets and liabilities 162 Identifiable net assets (liabilities) acquired (2,434) Noncontrolling interest (1,440) Goodwill (see Note 9) 5,373 Cash consideration transferred $ 1,499 Actual and Unaudited Pro Forma Results Our consolidated revenue and net income attributable to Comcast Corporation f or the year ende d December 31, 2015 included $ 169 million and $ 18 million, respectively, from the acquisition of Universal Studios Japan. The following unaudited pro forma information has been presented as if the acquisition occurred on January 1, 2014. This information is based on historical results of operations and is subject to change as valuations are completed and additional analysis is obtained. In addition, the unaudited pro forma accounting adjustments are not necessarily indicative of what our results would hav e been had we operated Universal Studios Japan si nce January 1, 2014. No pro forma adjustments have been made for our transaction-related expenses. Year ended December 31 (in millions except per share amounts) 2015 2014 Revenue $ 75,563 $ 69,860 Net income $ 8,640 $ 8,758 Net income attributable to Comcast Corporation $ 8,278 $ 8,463 Basic earnings per common share attributable to Comcast Corporation shareholders $ 3.33 $ 3.28 Diluted earnings per common share attributable to Comcast Corporation shareholders $ 3.29 $ 3.23 Time Warner Cable Merger and Related Divestiture Transactions On April 24, 2015, we and Time Warner Cable Inc. terminated our planned merger, and we terminated our related agreement with Charter Communications, Inc. to spin off, exchange and sell certain cable systems. In connection with these proposed transactions, we incurred incremental transaction-related expenses of $198 million and $237 million in 2015 and 2014, respectively. The transaction-related expenses are reflected primarily in other operating and administrative expenses, with $20 million recorded in depreciation and amortization expenses associated with the write-off of certain capitalized costs in 2015. 2013 NBCUniversal Redemption Transaction On March 19, 2013, we acquired General Electric Company’s (“GE”) 49% common equity interest in NBCUniversal Holdings that we did not already own for app roximately $16.7 billion (the “NBCUniversal redemption t ransaction”). In addition to th e NBCUniversal redemption transaction, NBCUniversal purchased from GE certain properties NBCUniversal occupies at 30 Rockefeller Plaza in New York City and CNBC’s headquarters in Englewood Cliffs, New Jersey for $1.4 billion. The total consideration for th ese transactions consisted of $11.4 billion of cash on hand; $4 billion of senior debt securities issued by NBCUniversal Enterprise, Inc. (“NBCUniversal Enterprise”), a holding company that we control and consolid ate following the close of the NBCUniversal redemption t ransaction whose principal assets are its interests in NBCUniversal Holdings; $750 million of cash funded through our commercial paper program; $1.25 billion of borrowings under NBCUniversal Enterprise’s credit facility, which replaced NBCUniv ersal’s credit facility; and $725 million aggregate liquidation preference of Series A cumulative preferred stock of NBCUniversal Enterprise. See Note 20 for additional information on our cross-guarantee structure. Because we maintained control of NB CUniversal Holdings, the difference between the consideration transferred and the recorded value of GE’s 49% redeemable noncontrolling common equity interest, and the related tax impacts, were recorded to additional paid-in capital. The NBCUniversal Enterp rise preferred stock pays dividends at a fixed rate of 5.25% per annum. The holders have the right to cause NBCUniversal Enterprise to redeem their shares at a price equal to the liquidation preference plus accrued but unpaid dividends for a 30 day period beginning on March 19, 2020 and thereafter on every third anniversary of such date (each such date, a “put date”). Shares of preferred stock can be called for redemption by NBCUniversal Enterprise at a price equal to the liquidation preference plus accrued but unpaid dividends one year following each put date applicable to such shares . Because certain of these redemption provisions are outside of our control, the NBCUniversal Enterprise preferred stock is presented outside of equity under the caption “redeemable noncontrolling interests and redeemable subsidiary preferred stock” in our consolidated balance sheet. Its initial value was based on the liquidation preference of the preferred stock and is adjusted for accrued but unpaid dividends. As of December 31, 2015 and 2014 , the fair value of the NBCUniversal Enterprise redeemable subsidiary preferred stock was $ 758 million and $ 751 million, respectively. The estimated fair values are based on Level 2 inputs that use pri cing models whose inputs are derived primarily from or corroborated by observable market data through correlation or other means for substantially the full term of the financial instrument.

Significant Transactions	Note 4 : Significant Transactions 2015 Universal Studios Japan On November 13, 2015, we acquired a 51% economic interest in Universal Studios Japan for $1.5 billion. The acquisition was funded through cash on hand and borrowings under our commercial paper program. Universal Studios Japan is a VIE based on the governance structure and we consolidate Universal Studio s Japan as we have the power to direct activities that most significantly impact its economic performance. There are no liquidity arrangements, guarantees, or other financial commitments between us and Universal Studios Japan, and therefore our maximum ris k of financial loss is our 51% interest. Universal Studios Japan’s results of operations are reported in our Theme Parks segment following the acquisition date. Preliminary Allocation of Purchase Price Due to the limited amount of time since the date of a cquisition, the assets and liabilities of Universal Studios Japan were recorded at their historical carrying value. We will adjust these amounts to fair value as valuations are completed and we obtain information necessary to complete the analyses, but no later than one year from the acquisition date. The 49% noncontrolling interest in Universal Studios Japan is recorded in the equity section of our consolidated financial statements and has been recorded based on the total value of Universal Studios Japan i mplied in the transaction. For purposes of this preliminary allocation, the excess of the total value implied in the transaction over the historical carrying value has been recorded as goodwill. The table below presents the preliminary allocation of the purchase price to the assets and liabilities of Universal Studios Japan. Preliminary Allocation of Purchase Price (in millions) Property and equipment (see Note 8) $ 642 Intangible assets (see Note 9) 57 Working capital (24) Debt (see Note 10) (3,271) Other noncurrent assets and liabilities and other 162 Identifiable net assets (liabilities) acquired (2,434) Noncontrolling interest (1,440) Goodwill (see Note 9) 5,373 Cash consideration transferred $ 1,499 Actual and Unaudited Pro Forma Results Our consolidated revenue and net income attributable to NBCUniversal for the year ended December 31, 2015 included $ 169 million and $ 18 million, respectively, from the acquisition of Universal Studios Japan. The following unaudited pro forma information has been presented as if the acquisition occurred on January 1, 2014. This information is based on historical results of operations and is subject to change as valuations are completed and additional analysis is obtained. In addition, the unaudited pro forma accounting adjustments are not necessarily indicative of what our results would have been had we operated Universal Studios Japan si nce January 1, 2014. No pro forma adjustments have been made for our transaction-related expenses. Year ended December 31 (in millions) 2015 2014 Revenue $ 29,514 $ 26,513 Net income $ 3,851 $ 3,463 Net income attributable to NBCUniversal $ 3,529 $ 3,198 2013 Redemption Transaction On March 19, 2013, Comcast acquired General Electric Company’s (“GE”) 49% common equity interest in NBCUniversal Holdings that it did not already own for approximately $16.7 billion (the “redemption transaction”). In addition to the redemption transaction, we purchased from GE certain properties we occupy at 30 Rockefeller Plaza in New York City and CNBC’s headquart ers in Englewood Cliffs, New Jersey for $1.4 billion. The total consideration for these transactions consisted of $11.4 billion of cash on hand (of which we funded $4.6 billion); $4 billion of senior debt securities issued by NBCUniversal Enterprise, Inc. (“NBCUniversal Enterprise”), a holding company whose principal assets are its interests in NBCUniversal Holdings; $750 million of cash funded through Comcast’s commercial paper program; $1.25 billion of borrowings under NBCUniversal Enterprise’s credit fa cility, which replaced our credit facility; and $725 million aggregate liquidation preference of Series A cumulative preferred stock of NBCUniversal Enterprise. Following the close of the redemption transaction, Comcast owns 96% of NBCUniversal Holdings’ common units and NBCUniversal Enterprise owns the rema ining 4%. NBCUniversal Enterprise is now a consolidated subsidiary of Comcast, but we do not have any ownership interests in NBCUniversal Enterprise. NBCUniversal Enterprise also owns all of NBCUniversal Holdings’ preferred units with a $9.4 billion aggreg ate liquidation preference. NBCUniversal Holdings is required to make quarterly payments to NBCUniversal Enterprise at an initial rate of 8.25% per annum on the $9.4 billion aggregate liquidation preference of the preferred units. On March 1, 2018, and the reafter on every fifth anniversary of such date, this rate will reset to 7.44% plus the yield on actively traded United States Treasury securities having a 5 year maturity. NBCUniversal Holdings has the right to redeem all of the preferred units during the 30 day period beginning on March 1, 2018, and NBCUniversal Enterprise has the right to cause NBCUniversal Holdings to redeem 15% of its preferred units during the 30 day period beginning on March 19, 2020. The price and units in a redemption initiated by either party will be based on the liquidation preference plus accrued but unpaid dividends and adjusted, in the case of an exercise of NBCUniversal Enterprise’s right, to the extent the equity value of NBCUniversal Holdings is less than the liquidation pre ference. Our cash flows are, and will continue to be, the primary source of funding for the required payments and for any future redemption of the NBCUniversal Holdings preferred units.

Related Party Transactions	Note 5 : Related Party Transactions In the ordinary course of our business, we enter into transactions with Comcast. We generate revenue from Comcast primarily from the distribution of our cable network programming and, to a lesser extent, the sale of advertising and our owned programming, and we incur expenses primarily related to advertising and various support services provided by Comcast to us. In 2013, as part of the Comcast cash management process , we and Comcast entered into revolving credit agreement s under which we can borrow up to $3 billion from Comcast and Comcast can borrow up to $3 billion from us. Amounts owed by us to Comcast under the revolving credit agreement, including accrued interest, are presented under the caption “note payable to Comcast” in our consolidated balance sheet . The revolving credit agreements bear interest at floating rates equal to the interest rate under the Comcast and Comcast Cable Communications, LLC revolving credit facility (the “Comcast revolving cred it facility”). The interest rate on the Comcast revolving credit facility consists of a base rate plus a borrowing margin that is determined based on Comcast’s credit rating. As of December 31, 2015 , the borrowing margin for London Interbank Offered Rate-based borrowings was 1.00% . In addition, Comcast is the counterparty to one of our contractual obligations. As of both December 31, 2015 and 2014 , the carrying value of the liability associated with this contractual obligation was $ 383 million. The following tables present transactions with Comcast and its consolidated subsidiaries that are included in our consolidated financial statements. Consolidated Balance Sheet December 31 (in millions) 2015 2014 Transactions with Comcast and Consolidated Subsidiaries Receivables, net $ 239 $ 229 Accounts payable and accrued expenses related to trade creditors $ 68 $ 47 Accrued expenses and other current liabilities $ 51 $ 8 Note payable to Comcast $ 1,750 $ 865 Other noncurrent liabilities $ 383 $ 383 Consolidated Statement of Income Year ended December 31 (in millions) 2015 2014 2013 Transactions with Comcast and Consolidated Subsidiaries Revenue $ 1,349 $ 1,315 $ 1,262 Operating costs and expenses $ (246) $ (162) $ (190) Other income (expense) $ (37) $ (43) $ - Distributions to NBCUniversal Holdings In addition to the transactions presented in the table above, we make distributions to NBCUniversal Holdings on a periodic basis to enable its owners to meet their obligations to pay taxes on taxable income generated by our businesses. We also make quarterly distributions to NBCUniversal Holdings to enable it to make its required quarterly payments to N BCUniversal Enterprise at an initial annual rate of 8.25% on the $9.4 billion aggregate liquidation preference of its preferred units. These distributions are presented under the caption “distributions to member” in our consolidated statement of cash flows . Following the close of the redemption t ransaction, none of these distributions to NBCUniversal Holdings are attributable to GE. In connection with the redemption t ransaction, we also made a distribution of $3.2 billion to NBCUniversal Holdings to fund a portion of the redemption t ransaction. This distribution is presented separately in our consolidated statement of cash flows. Transactions with GE Following the close of the redemption t ransaction and the subsequent sale of NBCUniversal Enterprise’s p referred stock and senior notes by GE to unaffiliated third parties in March 2013, we no longer consider GE to be a related party. In February 2013, Comcast closed an agreement with GE, General Electric Capital Corporation (“GECC”) and LIN TV under which, among other things, we purchased a note held by Station Venture Holdings, LLC (“Station Venture”) from GECC for $602 million, which effectively settled a liability of $482 million that had been recorded in the allocation of purchase price associated with C omcast’s acquisition of a controlling interest in NBCUniversal Holdings in 2011 (the “joint venture transaction”) . Due to the related party nature of this transaction, the excess of the purchase price of the Station Venture note over the recorded amount of the liability was recorded to member’s capital. Other than the Station Venture transaction and dividend paymen ts to GE that are included i n our consolidated statement of changes in equity and our consolidated statement of cash flows, the amounts related t o our transactions with GE and its consolidated subsidiaries that occu rred prior to the close of the redemption t ransaction were not material.

Through 2018 , we expect to amortize a pproximately 87% of unamort ized film and television costs for our released productions , excluding amounts allocated to acquired libraries. As of December 31, 2015 , acquired film and television libraries, which are included within the “released, less amortization” captions in the table above, had remaining unamortized costs of $ 449 million. These costs are generally amortized over a period not to exceed 20 years, and approximately 49% of these costs are expected t o be amortized through 2018 . Capitalization of Film and Television Costs We capitalize film and television production costs, including direct costs, production overhead, print costs, development costs and interest. We amortize capitalized film and tele vision production costs, including acquired libraries, and accrue costs associated with participation and residual payments to programming and production expenses. We generally record the amortization and the accrued costs using the individual film forecas t computation method, which amortizes such costs in the same ratio as the associated ultimate revenue. Estimates of ultimate revenue and total costs are based on anticipated release patterns, public acceptance and historical results for similar productio ns. Unamortized film and television costs, including acquired film and television libraries, are stated at the lower of unamortized cost or fair value. We do not capitalize costs related to the distribution of a film in movie theaters or the licensing or s ale of a film or television production, which are primarily costs associated with the marketing and distribution of film and television programming. In determining the estimated lives and method of amortization of acquired film and television libraries, w e generally use the method and the life that most closely follow the undiscounted cash flows over the estimated life of the asset. Upon the occurrence of an event or a change in circumstance that was known or knowable as of the balance sheet date and that indicates the fair value of a film is less than its unamortized costs, we determine the fair value of the film and record an impairment charge for the amount by which the unamortized capitalized costs exceed the film’s fair value. We enter into cofinanc ing arrangements with third parties to jointly finance or distribute certain of our film productions. Cofinancing arrangements can take various forms, but in most cases involve the grant of an economic interest in a film to an investor. The number of inves tors and the terms of these arrangements can vary, although investors generally assume full risk for the portion of the film acquired in these arrangements. We account for the proceeds received from a third-party investor under these arrangements as a redu ction to our capitalized film costs. In these arrangements, the investor owns an undivided copyright interest in the film, and therefore in each period we record either a charge or a benefit to programming and production expenses to reflect the estimate of the third-party investor’s interest in the profit or loss of the film. The estimate of the third-party investor’s interest in the profit or loss of a film is determined using the ratio of actual revenue earned to date to the ultimate revenue expected to b e recognized over the film’s useful life. We capitalize the costs of programming content that we license but do not own, including rights to multiyear, live-event sports programming, at the earlier of when payments are made for the programming or when the license period begins and the content is available for use. We amortize capitalized programming costs as the associated programs are broadcast. We amortize multiyear, live-event sports programming rights using the ratio of the current period revenue to the estimated ultimate revenue or under the terms of the contract. Acquired programming costs are recorded at the lower of unamortized cost or net realizable value on a program by program, package, channel or daypart basis. A daypart is an aggregation of p rograms broadcast during a particular time of day or programs of a similar type. Programming acquired by our Cable Networks segment is primarily tested on a channel basis for impairment, whereas programming acquired by our Broadcast Television segment is t ested on a daypart basis. If we determine that the estimates of future cash flows are insufficient or if there is no plan to broadcast certain programming, we recognize an impairment charge to programming and production expenses.

For AFS securities, we record unrealized gains or losses resulting from changes in fair value between measurement da tes as a component of other comprehensive income (loss), except when we consider declines in value to be other than temporary. For trading securities, we record unrealized gains or losses resulting from changes in fair value between measurement dates as a component of investment income (loss), net. We recognize realized gains and losses associated with our fair value method investments using the specific identification method. We classify the cash f lows related to purchases of and proceeds from the sale of trading securities based on the nature of the securities and the purpose for which they were acquired. Prepaid Forward Sale Agreements December 31 (in millions) 2014 Assets: Fair value equity securities held as collateral $ 523 Liabilities: Obligations under prepaid forward sale agreements $ 119 Derivative component of prepaid forward sale agreements 356 Total liabilities $ 475 During 2015 , we settled our remaining obligations under our prepaid forward sale agreements by delivering equity securities. As of December 31, 2015 , we have no remaining liabilities related to these obligations. As of December 31, 2014 , the majority of our fair value method investments were equity securities that we accounted for as trading securities and were held as collateral related to our obligations under prepaid forward sale agreements. As of December 31, 2014 , the carrying value of our remaining prepaid forward sale obligations approximated their fair value. The estimated fair values were based on Level 2 inputs that use pricing models whose inputs were derived primarily from or corroborated by observable market data through correla tion or other means for substantially the full term of the financial instrument. The derivative component of the prepaid forward sale agreements were equity derivative financial instruments embedded in the related contracts, which we used to manage our exp osure to and benefits from price fluctuations in the common stock of the related investments. For these derivative financial instruments, we separated the derivative component from the host contract and recorded in each period the change in its value to in vestment income (loss), net. Li berty Media In October 2013, Liberty Media Corporation (“Liberty Media”) redeemed 6.3 million shares of Liberty Media Series A common stock (“Liberty stock”) that had been held by us as collateral under certain of our prepaid forward sale agreements in exchange for all of the equity of a subsidiary of Liberty Media. The fair value of the Liberty stock at the date of the close of the transaction was $937 million. The assets of the subsidiary of Liberty Media included cash of $4 17 million, Liberty Media’s interests in one of NBCUniversal’s contractual obligations and a wholly owned operating subsidiary, Leisure Arts, Inc. Following the close of this transaction, we now consolidate the subsidiary transferred to us, and the liabili ty associated with NBCUniversal’s contractual obligation is eliminated in consolidation. Clearwire LLC In July 2013, in connection with Sprint Communications, Inc.’s (“Sprint”) acquisition of Clearwire Corporation (“ Clearwire ”), Sprint acquired our investment of 89 million Class A shares of Clearwire for $443 million. As a result, we recognized a pretax gain of $443 million in our consolidated statement of income, which represented the recognition of cumulative unrealized gain s previously recorded in accumulated other comprehensive income (loss). Equity Method We use the equity method to account for investments in which we have the ability to exercise significant influence over the investee’s operating and financial policies or where we hold significant partnership or LLC interests. Equity method investments are recorded at cost and are adjusted to recognize ( 1 ) our proportionate share of the investee’s net income or loss after the date of investment, ( 2 ) amortization of the rec orded investment that exceeds our share of the book value of the investee’s net assets, ( 3 ) additional contributions made and dividends received , and ( 4 ) impairments resulting from other-than-temporary declines in fair value. For some investments, we recor d our share of the investee’s net income or loss one quarter in arrears due to the timing of our receipt of such information. Gains or losses on the sale of equity method investments are recorded to other income (expense), net. If an equity method investee were to issue additional securities that would change our proportionate share of the entity, we would recognize the change, if any, as a gain or loss in our consolidated statement of income. The Weather Channel In June and December 2015, TWCC Holding Cor p. (“The Weather Channel”) recorded impairment charges related to goodwill. During 2015, we recorded expenses of $333 million that represent NBCUniversal’s proportionate share of these impairment charges, in equity in net income (losses) of investees, net in our consolidated statement of income. On January 29 , 2016, IBM acquired The Weather Channel’s product and technology businesses. The Weather Channel cable network was not acquired and, following the close of the transaction, licenses weather forecast data and analytics from IBM. In June 2013, we received a distribution from The Weather Channel of $152 million, of which $128 million was recorded as a return of our investment in The Weather Channel and included in other investing activities in our consol idated statement of cash flows. Hulu In July 2013, we entered into an agreement to provide capital contributions totaling $247 million to Hulu , LLC (“ Hulu ”), which we had previously accounted for as a cost method investment. This represented an agree ment to provide our first capital contribution to Hulu since we acquired our interest in it as part of our acquisition of a controlling interest in NBCUniversal Holdings in 2011 (the “ NBCUniversal transaction”) ; therefore , we began to apply the equity meth od of accounting for this investment. The change in the method of accounting for this investment required us to recognize our proportionate share of Hulu’s accumulated losses from the date of the NBCUniversal transaction through July 2013. In 2015, 2014 an d 2013, we recognized our proportionate share of losses of $ 106 million, $20 million and $142 million, respectively, related to our investment in Hulu . Cost Method We use the cost method to account for investments not accounted for under the fair value method or the equity method . Vox and BuzzFeed In September 2015, NBCUniversal made an additional investment in Vox Media, Inc. (“ Vox Media”) and acquired an interest in BuzzFeed , Inc. (“ BuzzFeed ”) for $200 million each in cash. Vox Media is a digital media company comprised of eight distinct brands. BuzzFeed is a global media company that produces and distributes original news, entertainment and v ideos. AirT ouch We hold two series of preferred stock of Verizon Americas, Inc., formerly known as AirTouch Communications, Inc. (“ AirTouch ”), a subsidiary of Verizon Communications Inc. , which are redeemable in April 2020. As of both December 31, 2015 and 2014 , t he estimated fair value of the AirTouch preferred stock was $ 1.7 billion . The dividend and redemption activity of the AirTouch preferred stock determines the dividend and redemption payments associated with substantially a ll of the preferred shares issued by one of our consolidated subsidiaries, which is a VIE. The subsidiary has three series of preferred stock outstanding with an aggregate redemption value of $ 1.75 billion. Substantially all of the AirTo uch preferred stock is redeemable in April 2020 at a redemption value of $ 1.65 billion. As of both December 31, 2015 and 2014 , the two series of redeemable subsidiary preferred shares were recorded at $ 1.6 bill ion, and those amounts are included in other noncurrent liabilities. As of both December 31, 2015 and 2014 , the liability related to the redeemable subsidiary preferred shares had an aggregate estimated fair value of $ 1.7 billion. The estimated fair values of the AirTouch preferred stock and redeemable subsidiary preferred shares are based on Level 2 inputs that use pricing models whose inputs are derived primarily from or corroborated by observable market data through correlation or other means for substantially the full term of the financial instrument. The one nonredeemable series of subsidiary preferred shares was recorded at $ 100 million as of both December 31, 2015 and 2014 , and those amounts are included in noncontrolling interests in our consolidated balance sheet. The carrying amount of the nonredeemable subsidiary preferred stock approximates its fair value. Impairment Testing of Investments We review our investment portf olio each reporting period to determine whether there are identified events or circumstances that would indicate there is a decline in the fair value that would be considered other than temporary. For our nonpublic investments, if there are no identified e vents or circumstances that would have a significant adverse effect on the fair value of the investment, then the fair value is not estimated. If an investment is deemed to have experienced an other-than-temporary decline below its cost basis, we reduce th e carrying amount of the investment to its quoted or estimated fair value, as applicable, and establish a new cost basis for the investment. For our AFS and cost method investments, we record the impairment to investment income (loss), net. For our equity method investments, we record the impairment to other income (expense), net. In 2013, we recorded $249 million of impairment charges to our equity method investments, which primarily related to a regional sports cable network based in Houston, Texas.

Equity method investments are recorded at cost and are adjusted to recognize ( 1 ) our proportionate share of the investee’s net income or loss after the date of investment, ( 2 ) amortization of the recorded investment that exceeds our share of the book value of the invest ee’s net assets, ( 3 ) additional contributions made and dividends received, and ( 4 ) impairments resulting from other-than-temporary declines in fair value. Gains or losses on the sale of equity method investments are recorded to other income (expense), net. If an equity method investee were to issue additional securities that would change our proportionate share of the entity, we would recognize the change, if any, as a gain or loss in our consolidated statement of income. The Weather Channel In June and Dec ember 2015, TWCC Holding Corp. (“The Weather Channel”) recorded impairment charges related to goodwill. During 2015, we recorded expenses of $333 million that represent our proportionate share of these impairment charges in equity in net income (losses) of investees, net in our consolidated statement of income . On January 29 , 2016, IBM acquired The Weather Channel’s product and technology b usinesses. The Weather Channel cable network was not acquired and, following the close of the transaction, licenses wea ther foreca st data and analytics from IBM. In June 2013, we received a distribution from The Weather Channel of $152 million, of which $128 million was recorded as a return of our investment in The Weather Channel and included in other investing activities in our consolidated statement of cash flows. Hulu In July 2013, we entered into an agreement to provide capital contributions totaling $247 million to Hulu, LLC (“Hulu”), which we had previously accounted for as a cost method investment. This represented an agreement to provide our first capital contribution to Hulu since Comcast acquired its interest in Hulu as part of the joint venture transaction; therefore , we began to apply the equity method of accounting for this investment. The change in the method of accounting for this investment required us to recognize our proportionate share of Hulu’s accumulated losses from the date of the j oint v enture transaction through July 2013. In 2015, 2014 and 2013, we rec ognized our proportionate share of losses of $ 106 million, $20 million and $142 million, respectively, related to our investment in Hulu.

In September 2015, we made an additional investment in Vox Media, Inc. (“ Vox Media”) and acquired an interest in BuzzFeed , Inc. (“ BuzzFeed ”) for $200 million each in cash. Vox Media is a digital media company comprised of eight distinct brands. BuzzFeed is a global media company that produces and distributes original news, entertainment and videos. Impairment Testing of Inve stments We review our investment portfolio each reporting period to determine whether there are identified events or circumstances that would indicate there is a decline in the fair value that would be considered other than temporary.

(b) Acquisitions in 2015 in our Theme Parks segment related to the Universal Studios Japan transaction (s ee Note 5 for additional information). We assess the recoverability of our goodwill annually, or more frequently whenever events or substantive changes in circumstances indicate that the carrying amount of a reporting unit may exceed its fair value. We test goodwill for impairment at the reporting unit level. To determine our reporting units, we evaluate the components one level be low the segment level and we aggregate the components if they have similar economic characteristics. As a result of this assessment, our reporting units are the same as our five reportable segments. We evaluate the determination of our reporting units used to test for impairment periodically or whenever events or substantive changes in circumstances occur. The assessment of recoverability may first consider qualitative factors to determine whether the existence of events or circumstances leads to a determin ation that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. A quantitative assessment is performed if the qualitative assessment results in a more-likely-than-not determination or if a qualitative assessm ent is not performed. The quantitative assessment considers if the carrying amount of a reporting unit exceeds its fair value, in which case an impairment charge is recorded to the extent the carrying amount of the reporting unit’s goodwill exceeds its imp lied fair value.

Our c able franchise rights represent the values we attributed to agreements with state and local authorities that allow access to homes and businesses in cable service areas acquired in business combinations . We do not amortize our cable franchise rights because we have determined that they meet the definition of indefinite-lived intangible assets since there are no legal, regulatory, contractual, competitive, economic or other factors which limit the period over which these rights will contribute to our cash flows. We reassess this determination periodically or whenever events or substantive changes in circumstances occur. Costs we incur in negotiating and renewing cable franchise agreements are included in o ther intangible assets and are generally amortized on a straight-line basis over the term of the franchise agreement. We assess the recoverability of our cable franchise rights and other indefinite-lived intangible assets annually, or more frequently whene ver events or substantive changes in circumstances indicate that the assets might be impaired. Our three Cable Communications divisions represent the unit of account we use to test for impairment for our cable franchise rights. We evaluate the unit of acco unt used to test for impairment of our cable franchise rights and other indefinite-lived intangible assets periodically or whenever events or substantive changes in circumstances occur to ensure impairment testing is performed at an appropriate level. The assessment of recoverability may first consider qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount . A quantitative assessment is performed if the qualitative assessment results in a more - likely - than - not determination or if a qualitative assessment is not performed. When performing a quantitative assessment, we estimate the fair value of our cable franchise rights and other indefinite-lived intangibl e assets primarily based on a discounted cash flow analysis that involves significant judgment . When analyzing the fair values indicated under the discounted cash flow models, we also consider multiples of operating income before depreciation and amortizat ion generated by the underlying assets, current market transactions, and profitability informatio n. If the fair value of our cable franchise rights or other indefinite-lived intangible assets were less than the carrying amount, we would recognize an impair ment charge for the difference between the estimated fair value and the carrying value of the assets. Unless presented separately, the impairment charge is included as a component of amortization expense. We did not recognize any material impairment charge s in any of the periods presented.

Our finite-lived intangible assets are amortized primarily on a straight-line basis over their estimated useful life or the term of the associated agreement. We capitalize direct development costs associated with internal-use software, including external dire ct costs of material and services and payroll costs for employees devoting time to these software projects. We also capitalize costs associated with the purchase of software licenses. We include these costs in other intangible assets and generally amortize them on a straight-line basis over a period not to exceed five years. We expense maintenance and training costs, as well as costs incurred during the preliminary stage of a project, as they are incurred. We capitalize initial operating system software costs and amor tize them over the life of the associated hardware. We evaluate the recoverability of our finite-lived intangible assets whenever events or substantive changes in circumstances indicate that the carrying amount may not be recoverable.

The estimated fair value of debt for which there are no quoted market prices is based on Level 2 inputs that use interest rates available to us for debt with similar terms and remaining maturities. Debt Principal Maturities (in millions) Weighted-Average Interest Rate as of December 31, 2015 2016 2.87 % $ 1,163 2017 3.45 % $ 120 2018 2.79 % $ 127 2019 3.05 % $ 226 2020 3.77 % $ 4,657 Thereafter 4.78 % $ 6,213 Term Loans As a result of the Universal Studios Japan transaction, we consolidated ¥400 billion of term loans having a final maturity of November 2020. In accordance with acquisition accounting, these debt securities were recorded at fair value as of the acquisition date. These term loans contain financial and operating covenants and are secured by the assets of Universal Studios Japan and the equity interests of the investors. We do not guarantee these term loans and they are otherwise nonrecourse to us . Debt Repayments In April 2015, we repaid at maturity $1 billion aggregate principal amount of 3.65% senior notes due 2015. Cross-Guarantee Structure W e, Comcast and a 100% owned ca ble holding company subsidiary of Comcast ( “ CCCL Parent ”) fully and unconditionally guarantee each other’s debt securities. As of Decemb er 31, 2015 , we guaranteed $35.1 billion of outstanding debt securities of Comcast and CCCL Parent . We also fully and unconditionally guarantee the Comcast revolving credit fa cility, of which no amounts were outstanding as of December 31, 2015 . We do not, however, guarantee the obligations of NBCUniversal Enterprise with respect to its $4 billion aggregate principal amount of senior notes, $1.35 billion revolving credit fac ility and associated commercial paper program, or $725 million liquidation preference of Series A cumulativ e preferred stock.

Fair Value Measurements	Note 11: Fair Value Measurements The accounting guidance related to financial assets and financial liabilities (“financial instruments”) establishes a hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques (market approach, income approach and cost approach). The levels of the hierarchy are described below. Level 1: Consists of financial instruments whose values are based on quoted market prices for identical financial instruments in an active market. Level 2: Consists of financial instruments that are valued using models or other valuation methodologies. These models use inputs that are observable either directly or indirectly. Level 2 inputs include (1) quoted prices for similar assets or liabilities in active markets, (2) quoted prices for identical or similar assets or liabilities in markets that are not active, (3) pricing models whose inputs are observable for substantially the full term of the financial instrument and (4) pricing models whose inputs are derived primarily from or corroborated by observable market data through correlation or other means for substantially the full term of the financial instrument. Level 3: Consists of financial instruments whose values are determined using pricing models that use significant inputs that are primarily unobservable, discounted cash flow methodologies or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of financial instruments and their classification within the fair value hierarchy. Financial instruments are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. There have been no changes in the classification of any financial instruments within the fair value hierarchy in the periods presented. Our financial instruments that are accounted for at fair value on a recurring basis are presented in the table below. Recurring Fair Value Measurements Fair Value as of December 31, 2015 Fair Value as of December 31, 2014 (in millions) Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets Trading securities $ 22 $ - $ - $ 22 $ 523 $ - $ - $ 523 Available-for-sale securities - 123 10 133 1 121 10 132 Interest rate swap agreements - 53 - 53 - 84 - 84 Other - 5 12 17 - 64 7 71 Total $ 22 $ 181 $ 22 $ 225 $ 524 $ 269 $ 17 $ 810 Liabilities Derivative component of prepaid forward sale agreements and indexed debt instruments $ - $ 5 $ - $ 5 $ - $ 361 $ - $ 361 Contractual obligation - - - - - - 883 883 Contingent consideration - - - - - - 644 644 Other - 86 - 86 - 8 - 8 Total $ - $ 91 $ - $ 91 $ - $ 369 $ 1,527 $ 1,896 Contractual Obligation As a result of the acquisition of the Universal Orlando theme park in 2011, we assumed a contractual obligation that involves an interest held by a third party in the revenue of certain theme parks. The arrangement provides the counterparty with the right to periodic payments associated with current period revenue and, beginning in 2017, the option to require NBCUniversal to purchase the interest for cash in an amount based on a contractually specified formula. The arrangement was recognized at fair value a t the time of the acquisition and the fair value has been adjusted periodically since the acquisition with the expectation that the arrangement would be settled in 2017, or shortly thereafter. It has a current carrying value of $1.1 billion and adjustments to fair value, as well as the periodic payments, have been presented in other income (expense), net in our consolidated statement of income. As a result of the continuing process of obtaining additional information and revising estimates, including in 20 15 the estimated impact on the arrangement of the Universal Studios Japan transaction and the planned development of a theme park in China, we no longer expect the settlement of the arrangement in 2017, or shortly thereafter. Accordingly, in the fourth quarter of 2015, we concluded that we should no longer adjust the arrangement to fair value and it is no longer presented in the recurring fair value measurements table. We also concluded that the amounts that are payable based on current period revenue sh ould be presented in other operating and administrative expenses. We believe these changes are preferable because they better reflect the economic substance of the arrangement as a revenue participation similar to those that exist in our film and televisio n agreements. The change in our method of accounting coupled with the change in likelihood of the settlement result in the method being applied prospectively, similar to a change in estimate. See Note 18 for the treatment of this change in method in our se gment reporting presentation. Contingent Consideration In June 2015, we settled a contingent consideration liability related to the acquisition of NBCUniversal, which was based upon future net tax benefits realized by us that would affect future payments to GE, for a payment of $ 450 million, which is included as a financing activity in our consolidated statement of cash flows. The settlement resulted in a gain of $ 240 million, which was recor ded to other income (expense), net in our consolidated statement of income. Nonrecurring Fair Value Measure ment s We have assets and liabilities that are required to be recorded at fair value on a nonrecurring basis when certain circumstances occur. In the case of film, television or stage play production costs, when an event or change in circumstance occurs that may indicate that the fair value of a production is less than its unamortized costs, we determine the fair value of the production and record an adjustment for the amount by which the unamortized capitalized costs exceed the production’s fair value. The estimated fair value of a production is based on Level 3 inputs that primarily use an analysis of future expected cash flows. A djustments to capitalized film and stage play production costs of $ 42 million, $ 26 million and $ 167 million were recorded in 2015 , 2014 and 2013 , respectively.

Postretirement Benefit Plans We sponsor various benefit plans that provide postretirement benefits to eligible employees based on years of service. The Comcast Postretirement Healthcare Stipend Program (the “stipend plan”) provides an annual stipend for reimbursement of healthcare costs to each eligible employee based on years of service. Under the stipend plan, we are not exposed to the increasing costs of healthcare because the benefits are fixed at a predetermined amount. NBCUniversal’s postretirement medical and life insurance plans provide continuous coverage to employees eligible to receiv e such benefits. A small number of eligible employees also participate in legacy plans of acquired companies. All of our postretirement benefit plans are un funded and substantially all of our postretirement benefit obligations are recorded to noncurrent l iabilities. The expense we recognize for our postretirement benefit plans is determined using certain assumptions, including the discount rate. Pension Plans NBCUniversal NBCUniversal sponsor s various qualified and nonqualified defined benefit plans for do mestic employees for which future benefits have been frozen since the beginning of 2013, therefore we did not recognize service costs related to our pension plans for the periods presented. The expense we recognize for our defined benefit plans is determin ed using certain assumptions, including the discount rate and the expected long-term rate of return on plan assets. We recognize the funded or unfunded status of our defined benefit plans as an asset or liability in our consolidated balance sheet and recog nize changes in the funded status in the year in which the changes occur in accumulated other comprehensive income (loss). In addition to the defined benefit plans it sponsors, NBCUniversal is also obligated to reimburse GE for future benefit payments to t hose participants who were vested in the supplemental pension plan sponsored by GE at the time of the NBCUniversal transaction in 2011. In September 2015, we settled all of our obligations related to the termination in December 2013 of the NBCUniversal qua lified pension plan. In connection with this final settlement, we fully funded the plan with an additional contribution of $ 20 million and recorded expense s of $ 27 mill ion in other operating and administrative expenses . Other In August 2013, we settled all of our obligations related to the termination in February 2012 of the qualified pension plan that provided benefits to former employees of a company we acquired as part of the AT&T Broadband transaction in 2002 . In connection with this final settlement, we fully funded the plan with an additional contribution of $55 million and recorded expenses of $74 million in other operating and adm inistrative expenses, which was previously recorded in accumulated other comprehensive income (loss) . Other Employee Benefits Deferred Compensation Plans We maintain unfunded, nonqualified deferred compensation plans for certain members of management and n onemployee directors (each, a “participant”). The amount of compensation deferred by each participant is based on participant elections. Participant accounts, except for those in the NBCUniversal plan, are credited with income primarily based on a fixed an nual rate. Participants in the NBCUniversal plan designate one or more valuation funds, independently established funds or indices that are used to determine the amount of investment gain or loss in the participant’s account. Participants are eligible to r eceive distributions from their account based on elected deferral periods that are consistent with the plans and applicable tax law. The table below presents the benefit obligation and interest expense for our deferred compensation plans. Year ended December 31 (in millions) 2015 2014 2013 Benefit obligation $ 2,038 $ 1,774 $ 1,434 Interest expense $ 171 $ 149 $ 128 We have purchased life insurance policies to recover a portion of the future payments related to our deferred compensation plans. As of December 31, 2015 and 2014 , the cash surrender value of these policies, which is recorded to other noncurrent assets, was $ 658 million and $ 628 million , respectively . Retirement Investment Plans We sponsor several 401(k) defined contribution retirement plans that allow eligible employees to contribute a portion of their compensati on through payroll deductions in accordance with specified plan guidelines. We make contributions to the plans that include matching a percentage of the employees’ contributions up to certain limits. In 2015 , 2014 and 2013 , expenses related to th ese plans totaled $ 416 million, $379 million and $324 million, respectively. Split-Dollar Life Insurance Agreements Pursuant to pre-existing contractual obligations, we have collateral assignment split-dollar life insurance agreements wi th select key current and former employees that require us to incur certain insurance-related costs. Under some of these agreements, our obligation to provide benefits to the employees extends beyond retirement. The table below presents the benefit obliga tion and expenses related to our split-dollar life insurance agreements . Year ended December 31 (in millions) 2015 2014 2013 Benefit obligation $ 233 $ 217 $ 212 Other operating and administrative expenses $ 67 $ 52 $ 50 Multiemployer Benefit Plans We participate in various multiemployer benefit plans, including pension and postretirement benefit plans, that cover some of our employees and temporary employees who are represented by labor unions. We also participate in other multiemployer benefit plans that provide health and welfare and retirement savings benefits to active and retired participants. We make p eriodic contributions to these plans in accordance with the terms of applicable collective bargaining agreements and laws but do not sponsor or administer these plans. We do not participate in any multiemployer benefit plans for which we consider our contr ibutions to be individually significant, and the largest plans in which we participate are funded at a level of 80% or greater. In 2015 , 2014 and 2013 , the total contributions we made to mult iemployer pension plans were $ 77 million, $58 million and $59 mi llion, respectively. In 2015 , 2014 and 2013 , the total contributions we made to multiemployer postretirement and other benefit plans were $ 119 million, $ 125 million and $ 98 million, respectively. If we cease to be obligated to make contributions or were to otherwise withdraw from participation in any of these plans, applicable law would require us to fund our allocable share of the unfunded vested benefits, which is known as a withdrawal liability. In addition, actions taken by other participating employers may lead to adverse changes in the financial condition of one of these plans, which could result in an increase in our withdrawal liability. Severance Benefits We prov ide severance benefits to certain former employees. A liability is recorded when payment is probable, the amount is reasonably estimable, and the obligation relates to rights that have vested or accumulated. In 2015 , 2014 and 2013 , we recorded severance costs of $ 181 million, $152 million and $160 million, respectively.

This reclassification became effective as of the close of business on December 11, 2015, at which time our Class A Special common stock was no longer outstanding and ceased trading on the NA SDAQ under the symbol CMCSK and instead became listed on the NASDAQ under the symbol CMCSA. There was no impact on basic and diluted EPS or the carrying value of total common stock as presented in our consolidated balance sheet because it was a one-for-one stock exchange. Common Stock In the aggregate, holders of our Class A common stock have 66 2 / 3 % of the voting power of our common stock and holders of our Class B common stock have 33 1 / 3 % of the voting power of our common stock. Each share of our Class B common stock is entitled to 15 votes. The number of votes held by each share of our Class A common stock depends on the number of shares of Class A and Class B common stock outstanding at any given time. The 33 1 / 3 % aggregate voting power of our Class B c ommon stock cannot be diluted by additional issuances of any other class of common stock.

In 2015 , 2014 and 2013 , we recor ded increases to additional paid-in capital of $ 311 million, $ 299 million and $ 244 million, respectively, which were the result of tax benefits associated with our share- based compensation plans. Stock Options and Restricted Share Units As of December 31, 2015, unless otherwise stated (in millions, except per share data) Stock Options RSUs Awards granted during 2015 18 9 Weighted-average exercise price of awards granted during 2015 $ 59.39 Stock options outstanding and nonvested RSUs 94 23 Weighted-average exercise price of stock options outstanding $ 36.63 Weighted-average fair value at grant date of nonvested RSUs $ 44.19 As of December 31, 2015 , substantially all of our stock options outstanding were net settled stock options. Net settled stock options, as opposed to stock options exercised with a cash payment, result in fewer shares being issued and no cash proceeds being received by us when the options are exercised. O ur share-based compensation primarily consists of awards of RSUs and stock options to certain employees and directors as part of our approach to long-term incentive compensation. Awards generally vest over a period of 5 years and in the case of stock optio ns, have a 10 year term. Additionally, through our employee stock purchase plans, employees are able to purchase shares of Comcast common stock at a discount through payroll deductions. The cost associated with our share-based compensation is based on an a ward’s estimated fair value at the date of grant and is recognized over the period in which any related services are provided. RSUs are valued based on the closing price of our common stock on the date of grant and are discounted for the lack of dividends, if any, during the vesting period. We use the Black-Scholes option pricing model to estimate the fair value of stock option awards. The table below presents the weighted-average fair value on the date of grant of RSUs and stock options awarded under our v arious plans and the related weighted-average valuation assumptions. Year ended December 31 2015 2014 2013 RSUs fair value $ 58.81 $ 47.91 $ 38.28 Stock options fair value $ 11.78 $ 11.11 $ 8.80 Stock Option Valuation Assumptions: Dividend yield 1.7 % 1.8 % 1.9 % Expected volatility 23.0 % 24.0 % 25.0 % Risk-free interest rate 1.6 % 2.2 % 1.3 % Expected option life (in years) 6.0 6.5 7.0

Recognized Share-Based Compensation Expense Year ended December 31 (in millions) 2015 2014 2013 Restricted share units $ 78 $ 69 $ 42 Stock options 10 16 15 Employee stock purchase plans 6 6 5 Total $ 94 $ 91 $ 62 As of December 31, 2015 , we had unrecognized pretax compensation expense of $ 150 million related to nonvested Comcast restricted share units (“RSUs”) and unrecognized pretax compensation expense of $21 million related to nonvested Comcast stock options that will be recognized over a weighted-average period of approximately 1.8 years and 2.0 years, respectively. Comcast maintains share-based compensation plans that prima rily consist of awards of RSUs and stock options to certain employees and directors as part of its approach to long-term incentive compensation. Awards generally vest over a period of 5 years and in the case of stock options, have a 10 year term. Additiona lly, through its employee stock purchase plans, employees are able to purchase shares of Comcast common stock at a discount through payroll deductions. Certain of our employees participate in these plans and the expense associated with their participation is settled in cash with Comcast. The cost associated with Comcast’s share-based compensation is based on an award’s estimated fair value at the date of grant and is recognized over the period in which any related services are provided. RSUs are valued base d on the closing price of Comcast common stock on the date of grant and are discounted for the lack of dividends, if any, during the vesting period. Comcast uses the Black-Scholes option pricing model to estimate the fair value of stock option awards. The table below presents the weighted-average fair value on the date of grant of RSUs and stock options awarded under Comcast’s various plans to employees of NBCUniversal and the related weighted-average valuation assumptions. Year ended December 31 2015 2014 2013 RSUs fair value $ 59.37 $ 48.04 $ 37.79 Stock options fair value $ 11.79 $ 11.09 $ 8.86 Stock Option Valuation Assumptions: Dividend yield 1.7 % 1.8 % 1.9 % Expected volatility 23.0 % 24.0 % 25.2 % Risk-free interest rate 1.6 % 2.2 % 1.3 % Expected option life (in years) 6.0 6.5 7.0

Income Taxes	Note 15: Income Taxes Components of Income Tax Expense Year ended December 31 (in millions) 2015 2014 2013 Current Expense (Benefit): Federal $ 3,210 $ 2,392 $ 3,183 State 570 174 581 Foreign 221 142 200 4,001 2,708 3,964 Deferred Expense (Benefit): Federal 890 1,000 (76) State 66 173 108 Foreign 2 (8) (16) 958 1,165 16 Income tax expense $ 4,959 $ 3,873 $ 3,980 Our income tax expense differs from the federal statutory amount because of the effect of the items detailed in the table below. Year ended December 31 (in millions) 2015 2014 2013 Federal tax at statutory rate $ 4,680 $ 4,363 $ 3,890 State income taxes, net of federal benefit 326 329 319 Foreign income taxes, net of federal credit 13 - 15 Nontaxable income attributable to noncontrolling interests (69) (62) (103) Adjustments to uncertain and effectively settled tax positions, net 15 (408) 58 Accrued interest on uncertain and effectively settled tax positions, net 73 (235) 114 Other (79) (114) (313) Income tax expense $ 4,959 $ 3,873 $ 3,980 We base our provision for income taxes on our current period income, changes in our deferred income tax assets and liabilities, income tax rates, changes in estimates of our uncertain tax positions, and tax planning opportunities available in the jurisdictions in which we operate. We recognize deferred tax assets and liabilities when there are temporary differences between the financial reporting basis and tax basis of our assets and liabilities and for the expected benefits of using net operating loss carryforwards . When a change in the tax rate or tax law has an impact on deferred taxes, we apply the change based on the years in which the temporary differences are expected to reverse. We record the change in our consolidated financial statements i n the period of enactment. The determination of the income tax consequences of a business combination includes identifying the tax basis of assets and liabilities acquired and any contingencies associated with uncertain tax positions assumed or resulting from the business combination. Deferred tax assets and liabilities related to temporary differences of an acquired entity are recorded as of the date of the business combination and are based on our estimate of the ultimate tax basis that will be accepted by the various tax authorities. We record liabilities for contingencies associated with prior tax returns filed by the acquired entity based on criteria set forth in the appropriate accounting guidance. We adjust the deferred tax accounts and the liabiliti es periodically to reflect any revised estimated tax basis and any estimated settlements with the various tax authorities. The effects of these adjustments are recorded to income tax expense. From time to time, we engage in transactions in which the tax co nsequences may be subject to uncertainty. In these cases, we evaluate our tax positions using the recognition threshold and the measurement attribute in accordance with the accounting guidance related to uncertain tax positions. Examples of these transacti ons include business acquisitions and dispositions , including consideration paid or received in connection with these transactions, certain financing transactions , and the allocation of inc ome among state and local tax jurisdictions . Significant judgment i s required in assessing and estimating the tax consequences of these transactions. We determine whether it is more likely than not that a tax position will be sustained on examination, including the resolution of any related appeals or litigation processes , based on the technical merits of the position. A tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to be recognized in our consolidated financial statements. We classify interest and pen alties, if any, associated with our uncertain tax positions as a component of income tax expense. NBCUniversal For U.S. federal income tax purposes, NBCUniversal Holdings is treated as a partnership and NBCUniversal is disregarded as an entity separate fro m NBCUniversal Holdings. Accordingly, neither NBCUniversal Holdings nor NBCUniversal and its subsidiaries incur any material current or deferred domestic income taxes. Following the close of the NBCUniversal r edemption t ransaction in March 2013, the taxabl e income of NBCUniversal Holdings and NBCUniversal is allocable entirely to us. We are indemnified by GE for any income tax liability attributable to the NBCUniversal contributed businesses for periods prior to the close of the NBCUniversal transaction in January 2011 and also for any income tax liability attributable to NBCUniversal Enterprise for periods prior to the date of the NBCUniversal r edemption t ransaction. We ha ve indemnified GE for any income tax liability attributable to the businesses we cont ributed to NBCUniversal for periods prior to the close of the NBCUniversal transaction . Current and deferred foreign income taxes are incurred by NBCUniversal’s foreign subsidiaries. In 2015 , 2014 and 2013 , NBCUniversal had foreign income before taxes of $704 million, $385 million and $524 million, respectively, on which foreign income tax expense was recorded. We recorded U.S. income tax expense on our allocable share of NBCUniversal’s income before domestic and foreign taxes, which was reduced b y a U.S. tax credit equal to our allocable share of NBCUniversal’s foreign income tax expense. Components of Net Deferred Tax Liability December 31 (in millions) 2015 2014 Deferred Tax Assets: Net operating loss carryforwards $ 551 $ 448 Differences between book and tax basis of long-term debt 115 116 Differences between book and tax basis of investments 101 - Nondeductible accruals and other 3,589 3,383 Less: Valuation allowance 342 375 4,014 3,572 Deferred Tax Liabilities: Differences between book and tax basis of property and equipment and intangible assets 36,392 35,112 Differences between book and tax basis of investments - 186 Differences between book and tax basis of indexed debt securities 457 534 Differences between book and tax basis of foreign subsidiaries and undistributed foreign earnings 731 504 37,580 36,336 Net deferred tax liability $ 33,566 $ 32,764 Changes in our net deferred tax liabilit y in 2015 that were not recorded as deferred income tax expense are primarily related to decreases of $ 28 m illion associated with items included in other comprehensive income (loss) and decreases of $132 million related to acquisitions made in 2015. Our net deferred tax liability includes $ 23 billion related to cable franchise rights that will remain unchanged unless we recognize an impairment or dispose of a cable franchise. As of December 31, 2015 , we had federal net operating loss carryforwards of $ 135 million and various state net operating loss carryforwards that expire in periods through 203 5 . As of December 31, 2015 , we also had foreign net operating loss carryforwards of $ 700 million th at are related to the foreign operations of NBCUniversal, the majority of which expire in periods through 202 5 . The determination of the realization of the state and foreign net operating loss carryforwards is dependent on our subsidiaries’ taxable income or loss, apportionment percentages, and state and foreign laws that can change from year to year and impact the amount of such carryforwards. We recognize a valuation allowance if we determine it is more likely than not that some portion, or all, of a defe rred tax asset will not be realized. As of December 31, 2015 and 2014 , our valuation allowance was primarily related to state and foreign ne t operating loss carryforwards. Uncertain Tax Positions Our uncertain tax positions as of December 31, 2015 totaled $ 1.1 billion, which exclude the federal benefits on state tax positions that were recorded as deferred income taxes . I nclud ed in our uncertain tax positions was $220 million related to tax positions of NBCUniversal a nd NBCUniversal Enterprise for which we have been indemnified by GE. If we were to recognize the tax benefit for our uncertain tax positions in the future, $ 592 m illion would impact our effective tax rate and the remaining amount would increase our deferre d income tax liability. The amount and timing of the recognition of any such tax benefit is dependent on the completion of examinations of our tax filings by the various tax authorities and the expiration of statutes of limitations. In 2014, we reduced our accruals for uncertain tax positions and the related accrued interest on these tax positions and, as a result, our income tax expense decreased by $759 million. It is reasonably possible that certain tax contests could be resolved within the next 12 month s that may result in a decrease in our effective tax rate.

As of December 31, 2015 and 2014 , $49 million and $44 million, respectivel y, of these amounts were related to tax positions of NBCUniversal and NBCUniversal Enterprise for which we have been indemnified by GE. During 2015, the IRS completed its examination of our income tax returns for the year 2013. Various states are examinin g our tax returns, with most of the periods relating to tax years 2000 and forward . The tax years of our state tax returns currently under examination vary by state.

Man y of NBCUniversal’s employees, including writers, directors, actors, technical and production personnel, and others, as well as some of its on-air and creative talent, are covered by collective bargaining agreements or works councils. As of December 31, 2015 , the total number of NBCUniversal full-time, part-time and hourly employees on its payroll covered by collective bargaining agreements was 7,500 full-time equivalent employees. Of this total, approximately 10 % o f these full-time equivalent employees were covered by collective bargaining agreements that have expired or are scheduled to expire during 2016 . W e, through Comcast Spectacor, have employment agreements with both players and coaches of the Philadelphia Flyers . Certain of these employment agreements, which provide for payments that are guaranteed regardless of employee injury or termination, are covered by disability insurance if certain conditions are met. The table below summarizes our minimum annual p rogramming and talent commitments and our minimum annual rental commitments for office space , equipment and transponder service agreements under operating leases. Programming and talent commitments include acquired film and television programming, includin g U.S. television rights to the Olympic Games through 2032, Sunday Night Football on NBC through the 2022-23 season, NASCAR on the NBC Sports Network through 2024 and other programming commitments, as well as various contracts with creative talent and employme nt agreements.

Year ended December 31 (in millions) 2015 2014 2013 Rental expense $ 608 $ 580 $ 616 Contingencies Antitrust Cases We are defendants in two purported class actions originally filed in December 2003 in the United States District Courts for the District of Massachusetts and the Eastern District of Pennsylvania. The potential class in the Massachusetts case, which has been transferred to the Eastern District of Pennsylvania, is our customer base in the “Boston Cluster” area, and the potential class in the Pennsylvania case is our customer base in the “Philadelphia and Chicago Clusters,” as those terms are defined in the complaints. In each case, the plaintiffs allege that certain customer exchange transactions with other cable providers resulted in unlawful horizontal market restraints in those areas and seek damages under antitrust statute s, including treble damages. Classes of Chicago Cluster and Philadelphia Cluster customers were certified in October 2007 and January 2010, respectively. We appealed the class certification in the Philadelphia Cluster case to the Third Circuit Court of Ap peals, which affirmed the class certification in August 2011. In June 2012, the U.S. Supreme Court granted our petition to review the Third Circuit Court of Appeals’ ruling and in March 2013, the Supreme Court ruled that the class had been improperly certi fied and reversed the judgment of the Third Circuit. In August 2013, the plaintiffs in the Philadelphia Cluster case moved to certify a new, smaller class, which we opposed in January 2014. In April 2014, the District Court granted our unopposed motion to de-certify the Chicago Cluster class and the plaint iffs’ unopposed motion to amend the Pennsylvania case so as to dismiss claims relating to the Chicago C luster. In April 2014, lead counsel for the Boston Cluster cases withdrew, and in June 2014, new couns el requested the Boston Cluster cases be transferred to the federal court in Boston or permission to leave to amend the complaints . The District Court denied the request and dismissed the Boston Cluster case s . In December 2014, the District Court granted preliminary approval to a settl ement of the Philadelphia C luster case, and in September 2015, the District Court granted final approval of the settlement . The settlement of the Philadelphia C luster case did not have a material effect on our results of ope rations, cash flows or financial position. In addition, we are the defendant in putative class ac tions filed in federal district courts throughout the country. Twenty-three actions were consolidated by the Judicial Panel on Multidistrict Litigatio n in the United States District Court for the Eastern District of Pennsylvania for pre-trial proceedings. In a consolidated complaint filed in November 2009 on behalf of all plaintiffs in the multidistrict litigation, the plaintiffs allege that we improper ly “tie” the rental of set-top boxes to the provision of premium cable services in violation of Section 1 of the Sherman Antitrust Act, various state antitrust laws and unfair/deceptive trade practices acts. The West Virginia Attorney General also filed a complaint in West Virginia state court in July 2009 alleging that we improperly “tie” the rental of set-top boxes to the provision of digital cable services in violation of the West Virginia Antitrust Act and the West Virginia Consumer Credit and Protectio n Act. The Attorney General also alleges a claim for unjust enrichment/restitution. We removed the case to the United States District Court for West Virginia, and it was subsequently transferred to the United States District Court for the Eastern District of Pennsylvania and consolidated with the multidistrict litigation . In July 2011, we moved to compel arbitration of most of the plaintiffs’ claims and to stay the remai ning claims pending arbitration . A comprehensive settlement agreement for all 23 cases t hat had been submitted to the District Court for preliminary approval in June 2013 was withdrawn in October 2014, and we refiled our motion to compel arbitration . The parties submitted a settlement for the claims of current and former customers who receive d service in the states of California, Washington and West Virginia in September 2015. In November 2015, the District Court did not approve the settlement, and the plaintiffs then appealed the decision to the Third Circuit Court of Appeals. We do not expect these cases to have a material effect on our results of operations, cash flows or financial position. Other We are a defendant in several unrelated lawsuits claiming infringement of various patents relating to various aspects of our busin esses. In certain of these cases other industry participants are also defendants, and also in certain of these cases we expect that any potential liability would be in part or in whole the responsibility of our equipment and technology vendors under applic able contractual indemnification provisions. We are also subject to other legal proceedings and claims that arise in the ordinary course of our business. While the amount of ultimate liability with respect to such actions is not expected to materially affe ct our results of operations, cash flows or financial position, any litigation resulting from any such legal proceedings or claims could be time-consuming and injure our reputation.

For each of 2015 , 2014 and 2013 , 2.8 % of Cable Communications revenue was derived from franchise and other regulatory fees. (b) Beginning in 2014, Fandango, our movie ticketing and entertainment business that was previously presented in our Cable Networks segment, is now presen ted in the Filmed Entertainment segment to reflect the change in our management reporting presentation. Due to immateriality, prior period amounts have not been adjusted. (c) The revenue and operating costs and expenses associated with our broadcast of t he 201 5 Super Bowl were reported in our Broadcast Television segment . The revenue and operating costs and expenses associated with our broadcast of the 2014 Sochi Olympics were reported in our Cable Networks and Broadcast Television segments. (d) As discl osed in Note 11, we changed our method of accounting for a contractual obligation that involves an interest in the revenue of certain theme parks. As a result of the change, beginning in the fourth quarter of 2015, amounts payable based on current period r evenue are presented in operating costs and expenses. Amounts paid through the third quarter of 2015 were included in other income (expense), net in our consolidated statement of income. For segment reporting purposes, we have adjusted periods prior to the fourth quarter of 2015 to reflect management reporting presentation for this expense on a consistent basis for all periods in the Theme Parks segment, which resulted in an offsetting adjustment in NBCUniversal Eliminations. Therefore, we have reduced our Theme Parks segment operating income before depreciation and amortization and operating income by $63 million, $72 million and $61 million in 2015, 2014 and 2013, respectively, while corresponding amounts have been reflected in NBCUniversal E liminations to reconcile to consolidated operating income. ( e ) NBCUniversal Headquarters and Other activities include costs associated with overhead, allocations , personnel costs and headquarter initiatives . ( f ) Included in Eliminations are transactions that our segmen ts enter into with one another. The most common types of transactions are the following: • our Cable Networks and Broadcast Television segments generate revenue by selling programming to our Cable Communications segment, which represents a substantial maj ority of the revenue elimination amount • our Cable Communications segment generates revenue by selling advertising and by selling the use of satellite feeds to our Cable Networks segment • our Filmed Entertainment and Broadcast Television segments gener ate revenue by licensing content to our Cable Networks segment • our Cable Communications segment receives incentives offered by our Cable Networks segment in connection with its distribution of the Cable Networks’ content that are recorded as a reduction to programming expenses ( g ) Revenue from custo mers located outside of the United States , primarily in Europe and Asia, in 2015 , 2014 and 2013 was $ 5.8 billion, $ 4.4 billion and $ 4.8 billion, respectively . No single customer accounted for a significant amount of revenue in any period. ( h ) We use operating income (loss) before depreciation and amortization, excluding impairment charges related to fixed and intangible assets and gains or losses from the sale of assets, if any, as the measure of profit or loss for our operating segments. This measure eliminates the significant level of noncash depreciation and amortization expense that results from the capital-intensive nature of certain of our businesses and from intangible assets recognized in business combinations. Additionally, i t is unaffected by our capital structure or investment activities. We use this measure to evaluate our consolidated operating performance and the operating pe rformance of our operating segments and to allocate resources and capital to our operating segments. It is also a significant performance measure in our annual incentive compensation programs. We believe that this measure is useful to investors because it is one of the bases for comparing our operating performance with that of other companies in our industries, although our measure may not be directly comparable to similar measures used by other companies. This measure should not be considered a substitute for operating income (loss), net income (loss) attributable to Comcast Corporation, net cash provided by operating activities, or other measures of performance or liquidity we have reported in accordance with GAAP.

Accounting Policies (Policy)

Accounting Policies (Policy)	12 Months Ended
	Dec. 31, 2015
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements include all entities in which we have a controlling voting interest and variable interest entities (“VIEs”) required to be consolidated in accordance with generall y accepted accounting principles in the United States (“GAAP”).
Foreign Currency Translation	We translate assets and liabilities of our foreign operations where the functional currency is the local currency, primarily the euro, British pound, and Japanese yen , into U.S. dollars at the exchange rate as of the balance sheet date and translate revenue and expenses using average monthly exchange rates. The related translation adjustments are recorded as a component of accumulated othe r comprehensive income (loss). Any foreign currency t ransaction gains and losses are included in our consolidated statement of income .
Cash Equivalents	Cash Equivalents The carrying amounts of our cash equivalents approximate their fair values. Our cash equivalents consist primarily of money market funds and U.S. government obligations, as well as commercial paper and certificates of deposit with maturities of three months or less when purchased.
Use of Estimates	Our consolidated financial statements are prepared in accordance with GAAP, which requires us to select accounting policies, including in certain cases industry-specific policies, and make estimates that affect the reported amount of assets, liabilities, revenue and expenses, and the related disclosure of contingent assets and contingent liabilities. Actual results could differ from these estimates. We believe that the judgments and related estimates for the followin g items are critical in the preparation of our consolidated financial statements: valuation and impairment testing of cable franchise rights (see Note 9) film and television costs (see Note 6) In addition, the following accounting policies are specific to the industries in which we operate: capitalization and amortization of film and television costs (see Note 6) installation revenue and costs for connecting customers to our cable systems (see revenue recognition below and Note 8) In formation on our other accounting policies and methods that are used in the preparation of our consolidated financial statements are included, where applicable, in their respective footnotes that follow. Below is a discussion of accounting policies and met hods used in our consolidated financial statements that are not presented within other footnotes.
Film And Television Costs	Capitalization of Film and Television Costs We capitalize film and television production costs, including direct costs, production overhead, print costs, development costs and interest. We amortize capitalized film and tele vision production costs, including acquired libraries, and accrue costs associated with participation and residual payments to programming and production expenses. We generally record the amortization and the accrued costs using the individual film forecas t computation method, which amortizes such costs in the same ratio as the associated ultimate revenue. Estimates of ultimate revenue and total costs are based on anticipated release patterns, public acceptance and historical results for similar productio ns. Unamortized film and television costs, including acquired film and television libraries, are stated at the lower of unamortized cost or fair value. We do not capitalize costs related to the distribution of a film in movie theaters or the licensing or s ale of a film or television production, which are primarily costs associated with the marketing and distribution of film and television programming. In determining the estimated lives and method of amortization of acquired film and television libraries, w e generally use the method and the life that most closely follow the undiscounted cash flows over the estimated life of the asset. Upon the occurrence of an event or a change in circumstance that was known or knowable as of the balance sheet date and that indicates the fair value of a film is less than its unamortized costs, we determine the fair value of the film and record an impairment charge for the amount by which the unamortized capitalized costs exceed the film’s fair value. We enter into cofinanc ing arrangements with third parties to jointly finance or distribute certain of our film productions. Cofinancing arrangements can take various forms, but in most cases involve the grant of an economic interest in a film to an investor. The number of inves tors and the terms of these arrangements can vary, although investors generally assume full risk for the portion of the film acquired in these arrangements. We account for the proceeds received from a third-party investor under these arrangements as a redu ction to our capitalized film costs. In these arrangements, the investor owns an undivided copyright interest in the film, and therefore in each period we record either a charge or a benefit to programming and production expenses to reflect the estimate of the third-party investor’s interest in the profit or loss of the film. The estimate of the third-party investor’s interest in the profit or loss of a film is determined using the ratio of actual revenue earned to date to the ultimate revenue expected to b e recognized over the film’s useful life. We capitalize the costs of programming content that we license but do not own, including rights to multiyear, live-event sports programming, at the earlier of when payments are made for the programming or when the license period begins and the content is available for use. We amortize capitalized programming costs as the associated programs are broadcast. We amortize multiyear, live-event sports programming rights using the ratio of the current period revenue to the estimated ultimate revenue or under the terms of the contract. Acquired programming costs are recorded at the lower of unamortized cost or net realizable value on a program by program, package, channel or daypart basis. A daypart is an aggregation of p rograms broadcast during a particular time of day or programs of a similar type. Programming acquired by our Cable Networks segment is primarily tested on a channel basis for impairment, whereas programming acquired by our Broadcast Television segment is t ested on a daypart basis. If we determine that the estimates of future cash flows are insufficient or if there is no plan to broadcast certain programming, we recognize an impairment charge to programming and production expenses.
Investments	Fair Value Method We classify publicly traded investments that are not accounted for under the equity method as available-for-sale (“AFS”) or trading securities and record them at fair value. For AFS securities, we record unrealized gains or losses resulting from changes in fair value between measurement da tes as a component of other comprehensive income (loss), except when we consider declines in value to be other than temporary. For trading securities, we record unrealized gains or losses resulting from changes in fair value between measurement dates as a component of investment income (loss), net. We recognize realized gains and losses associated with our fair value method investments using the specific identification method. We classify the cash f lows related to purchases of and proceeds from the sale of trading securities based on the nature of the securities and the purpose for which they were acquired. Equity Method We use the equity method to account for investments in which we have the ability to exercise significant influence over the investee’s operating and financial policies or where we hold significant partnership or LLC interests. Equity method investments are recorded at cost and are adjusted to recognize ( 1 ) our proportionate share of the investee’s net income or loss after the date of investment, ( 2 ) amortization of the rec orded investment that exceeds our share of the book value of the investee’s net assets, ( 3 ) additional contributions made and dividends received , and ( 4 ) impairments resulting from other-than-temporary declines in fair value. For some investments, we recor d our share of the investee’s net income or loss one quarter in arrears due to the timing of our receipt of such information. Gains or losses on the sale of equity method investments are recorded to other income (expense), net. If an equity method investee were to issue additional securities that would change our proportionate share of the entity, we would recognize the change, if any, as a gain or loss in our consolidated statement of income. Cost Method We use the cost method to account for investments not accounted for under the fair value method or the equity method . Impairment Testing of Investments We review our investment portf olio each reporting period to determine whether there are identified events or circumstances that would indicate there is a decline in the fair value that would be considered other than temporary. For our nonpublic investments, if there are no identified e vents or circumstances that would have a significant adverse effect on the fair value of the investment, then the fair value is not estimated. If an investment is deemed to have experienced an other-than-temporary decline below its cost basis, we reduce th e carrying amount of the investment to its quoted or estimated fair value, as applicable, and establish a new cost basis for the investment. For our AFS and cost method investments, we record the impairment to investment income (loss), net. For our equity method investments, we record the impairment to other income (expense), net.
Property and Equipment	Property and equipment are stated at cost. We capitalize improvements that extend asset lives and expense repairs and maintenance costs as incurred. We record depreciation using the straight-line method over the asset’s estimated useful life. For assets that are sold or retired, we remove the applicable cost and accumulated depreciation and, unless the gain or loss on disposition is presented separately, we recognize it as a component of depreciation expense. In accordance with accounting guidance relate d to cable television companies, we capitalize the costs associated with the construction of and improvements to our cable transmission and distribution facilities , costs associated with acquiring and deploying new customer premise equipment, and costs asso ciated with installation of our services. Costs capitalized include all direct costs for labor and materials, as well as various indirect costs. All costs incurred in connection with subsequent disconnects and reconnects are expensed as they are incurred. We evaluate the recoverability of our property and equipment whenever events or substantive changes in circumstances indicate that the carrying amount may not be recoverable. The evaluation is based on the cash flows generated by the underlying asset grou ps, including estimated future operating results, trends or other determinants of fair value. If the total of the expected future undiscounted cash flows were less than the carrying amount of the asset group, we would recognize an impairment charge to the extent the carrying amount of the asset group exceed ed its estimated fair value. Unless presented separately, the impairment charge is included as a component of depreciation expense.
Goodwill and Intangible Assets	We assess the recoverability of our goodwill annually, or more frequently whenever events or substantive changes in circumstances indicate that the carrying amount of a reporting unit may exceed its fair value. We test goodwill for impairment at the reporting unit level. To determine our reporting units, we evaluate the components one level be low the segment level and we aggregate the components if they have similar economic characteristics. As a result of this assessment, our reporting units are the same as our five reportable segments. We evaluate the determination of our reporting units used to test for impairment periodically or whenever events or substantive changes in circumstances occur. The assessment of recoverability may first consider qualitative factors to determine whether the existence of events or circumstances leads to a determin ation that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. A quantitative assessment is performed if the qualitative assessment results in a more-likely-than-not determination or if a qualitative assessm ent is not performed. The quantitative assessment considers if the carrying amount of a reporting unit exceeds its fair value, in which case an impairment charge is recorded to the extent the carrying amount of the reporting unit’s goodwill exceeds its imp lied fair value. Unless presented separately, the impairment charge is included as a component of amortization expense. Indefinite-Lived Intangible Assets Indefinite-lived intangible assets consist primarily of our cable franchise rights, as well as trade names and FCC licenses. Our c able franchise rights represent the values we attributed to agreements with state and local authorities that allow access to homes and businesses in cable service areas acquired in business combinations . We do not amortize our cable franchise rights because we have determined that they meet the definition of indefinite-lived intangible assets since there are no legal, regulatory, contractual, competitive, economic or other factors which limit the period over which these rights will contribute to our cash flows. We reassess this determination periodically or whenever events or substantive changes in circumstances occur. Costs we incur in negotiating and renewing cable franchise agreements are included in o ther intangible assets and are generally amortized on a straight-line basis over the term of the franchise agreement. We assess the recoverability of our cable franchise rights and other indefinite-lived intangible assets annually, or more frequently whene ver events or substantive changes in circumstances indicate that the assets might be impaired. Our three Cable Communications divisions represent the unit of account we use to test for impairment for our cable franchise rights. We evaluate the unit of acco unt used to test for impairment of our cable franchise rights and other indefinite-lived intangible assets periodically or whenever events or substantive changes in circumstances occur to ensure impairment testing is performed at an appropriate level. The assessment of recoverability may first consider qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount . A quantitative assessment is performed if the qualitative assessment results in a more - likely - than - not determination or if a qualitative assessment is not performed. When performing a quantitative assessment, we estimate the fair value of our cable franchise rights and other indefinite-lived intangibl e assets primarily based on a discounted cash flow analysis that involves significant judgment . When analyzing the fair values indicated under the discounted cash flow models, we also consider multiples of operating income before depreciation and amortizat ion generated by the underlying assets, current market transactions, and profitability informatio n. If the fair value of our cable franchise rights or other indefinite-lived intangible assets were less than the carrying amount, we would recognize an impair ment charge for the difference between the estimated fair value and the carrying value of the assets. Unless presented separately, the impairment charge is included as a component of amortization expense. We did not recognize any material impairment charge s in any of the periods presented. Finite-Lived Intangible Assets Finite-lived intangible assets are subject to amortization and consist primarily of customer relationships acquired in business combinations, software, cable franchise renewal cost s, contractual operating rights and intellect ual property rights . Our finite-lived intangible assets are amortized primarily on a straight-line basis over their estimated useful life or the term of the associated agreement. We capitalize direct development costs associated with internal-use software, including external dire ct costs of material and services and payroll costs for employees devoting time to these software projects. We also capitalize costs associated with the purchase of software licenses. We include these costs in other intangible assets and generally amortize them on a straight-line basis over a period not to exceed five years. We expense maintenance and training costs, as well as costs incurred during the preliminary stage of a project, as they are incurred. We capitalize initial operating system software costs and amor tize them over the life of the associated hardware. We evaluate the recoverability of our finite-lived intangible assets whenever events or substantive changes in circumstances indicate that the carrying amount may not be recoverable. The evaluation is ba sed on the cash flows generated by the underlying asset groups, including estimated future operating results, trends or other determinants of fair value. If the total of the expected future undiscounted cash flows were less than the carrying amount of the asset group, we would recognize an impairment charge to the extent the carrying amount of the asset group exceed ed its estimated fair value. Unless presented separately, the impairment charge is included as a component of amortization expense.
Asset Retirement Obligations	Asset Retirement Ob ligations Certain of our cable franchise agreements and lease agreements contain provisions requiring us to restore facilities or remove property in the event that the franchise or lease agreement is not renewed. We expect to continually renew our cable fr anchise agreements and therefore cannot reasonably estimate any liabilities associated with such agreements. A remote possibility exists that franchise agreements could be terminated unexpectedly, which could result in us incurring significant expense in c omplying with restoration or removal provisions. We do not have any significant liabilities related to asset retirements recorded in our consolidated financial statements .
Revenue Recognition	Revenue Recognition Cable Communications Segment Our Cable Communications segment generates revenue primarily from subscriptions to our video, high-speed Inte rnet and voice services (“cable services”) and from the sale of advertising. We recognize revenue from cable services as each service is provided. Customers are typically billed in advance on a monthly basis based on the services and features they receive and the type of equipment they use. Since installation revenue obtained from the connection of customers to our cable systems is less than the related direct selling costs, we recognize revenue as connections are completed. We manage credit risk by screeni ng applicants through the use of internal customer information, identification verification tools and credit bureau data. If a customer’s account is delinquent, various measures are used to collect outstanding amounts, including termination of the customer ’s cable services. As part of our distribution agreements with cable networks, we generally receive an allocation of scheduled advertising time on cable networks that our Spotlight business sells to local, regional and national advertisers. We recognize a dvertising revenue when the advertising is aired or viewed. In most cases, the available advertising units are sold by our sales force. In some cases, we work with representation firms as an extension of our sales force to sell a portion of the advertising units allocated to us. We also represent the advertising sales efforts of other multichannel video providers in some markets. Since we are acting as the principal in these arrangements, we record the advertising that is sold in revenue and the fees paid t o representation firms and multichannel video providers in other operating and administrative expenses. Revenue earned from other sources, such as our home security and automation services, is recognized when services are provided or events occur. Under the terms of our cable franchise agreements, we are generally required to pay to the cable franchising authority an amount based on our gross video revenue. We normally pass these fees through to our cable services customers and classify the fees as a comp onent of revenue with the corresponding costs included in other operating and administrative expenses. Cable Networks and Broadcast Television Segments Our Cable Networks segment generates revenue primarily from the distribution of our cable network progra mming to multichannel video providers, from the sale of advertising on our cable networks and related digital media properties, from the licensing of our owned programming through various distribution platforms, from the sale of our owned programming throu gh digital distribution services such as iTunes, and from the programming our cable production studio sells to third-party networks and subscription video on demand services. Our Broadcast Television segment generates revenue primarily from the sale of adv ertising on our broadcast networks, owned local broadcast television stations and related digital media properties, from the licensing of our owned programming through various distribution platforms, including to cable and broadcast networks, from the fees received under retransmission consent agreements and from the programming our broadcast television production studio sells to third-party networks and subscription video on demand services. We recognize revenue from distributors as programming is provided , generally under multiyear distribution agreements. From time to time, the distribution agreements expire while programming continues to be provided to the distributor based on interim arrangements while the parties negotiate new contract terms. Revenue r ecognition is generally limited to current payments being made by the distributor, typically under the prior contract terms, until a new contract is negotiated, sometimes with effective dates that affect prior periods. Differences between actual amounts de termined upon resolution of negotiations and amounts recorded during these interim arrangements are recorded in the period of resolution. Advertising revenue for our Cable Networks and Broadcast Television segments is recognized in the period in which comm ercials are aired or viewed. In some instances, we guarantee audience ratings for the commercials. To the extent there is a shortfall in the ratings that were guaranteed, a portion of the revenue is deferred until the shortfall is settled, primarily by pro viding additional advertising units. We recognize revenue from the licensing of our owned programming and programming produced by our studios for third parties when the content is available for use by the licensee, and when certain other conditions are met . When license fees include advertising time, we recognize the component of revenue associated with the advertisements when they are aired or viewed. Filmed Entertainment Segment Our Filmed Entertainment segment generates revenue primarily from the worldwide distribution of our produced and acquired films for exhibition in movie theaters, from the licensing of our owned and acquired films through various distribution platforms, and from the sale of our owned and acquired films on standard-definition video discs and Blu-ray discs (together, “DVDs”) and through digital distribution services. Our Filmed Entertainment segment also generates revenue from producing and licensing live stage plays, from the distribution of filmed entertainment produced by thi rd parties, and from Fandango, our movie ticketing and entertainment business. We recognize revenue from the distribution of films to movie theaters when the films are exhibited. We recognize revenue from the licensing of a film when the film is available for use by the licensee, and when certain other conditions are met. We recognize revenue from DVD sales, net of estimated returns and customer incentives, on the date that DVDs are delivered to and made available for sale by retailers. Theme Parks Segment Our Theme Parks segment generates revenue primarily from ticket sales and guest spending at our Universal theme parks in Orlando, Florida; Hollywood, California; and, as of November 2015, Osaka, Japan, as well as from licensing and other fees. We recogni ze revenue from advance theme park ticket sales when the tickets are used. For annual passes, we recognize revenue on a straight-line basis over the period following the activation date.
Cable Communications Programming Expenses	Cable Communications Programming Expenses Cable Commu nications programming expenses are the fees we pay to license the programming we distribute to our video customers. Programming is generally acquired under multiyear distribution agreements, with rates typically based on the number of customers that receiv e the programming, channel positioning and the extent of distribution. From time to time, these contracts expire and programming continues to be provided under interim arrangements while the parties negotiate new contract terms, sometimes with effective da tes that affect prior periods. While payments are typically made under the prior contract’s terms, the amount of programming expenses recorded during these interim arrangements is based on our estimates of the ultimate contract terms expected to be negotia ted. Differences between actual amounts determined upon resolution of negotiations and amounts recorded during these interim arrangements are recorded in the period of resolution. When our Cable Communications segment receives incentives from cable networ ks for the licensing of their programming, we defer a portion of these incentives, which are included in other current and noncurrent liabilities, and recognize them over the term of the contract as a reduction to programming expenses.
Advertising Expenses	Advertising Expense s Advertising costs are expensed as incurred.
Share-Based Compensation	As of December 31, 2015 , substantially all of our stock options outstanding were net settled stock options. Net settled stock options, as opposed to stock options exercised with a cash payment, result in fewer shares being issued and no cash proceeds being received by us when the options are exercised. O ur share-based compensation primarily consists of awards of RSUs and stock options to certain employees and directors as part of our approach to long-term incentive compensation. Awards generally vest over a period of 5 years and in the case of stock optio ns, have a 10 year term. Additionally, through our employee stock purchase plans, employees are able to purchase shares of Comcast common stock at a discount through payroll deductions. The cost associated with our share-based compensation is based on an a ward’s estimated fair value at the date of grant and is recognized over the period in which any related services are provided. RSUs are valued based on the closing price of our common stock on the date of grant and are discounted for the lack of dividends, if any, during the vesting period. We use the Black-Scholes option pricing model to estimate the fair value of stock option awards. The table below presents the weighted-average fair value on the date of grant of RSUs and stock options awarded under our v arious plans and the related weighted-average valuation assumptions.
Postretirement and Pension Benefits	All of our postretirement benefit plans are un funded and substantially all of our postretirement benefit obligations are recorded to noncurrent l iabilities. The expense we recognize for our postretirement benefit plans is determined using certain assumptions, including the discount rate. NBCUniversal NBCUniversal sponsor s various qualified and nonqualified defined benefit plans for do mestic employees for which future benefits have been frozen since the beginning of 2013, therefore we did not recognize service costs related to our pension plans for the periods presented. The expense we recognize for our defined benefit plans is determin ed using certain assumptions, including the discount rate and the expected long-term rate of return on plan assets. We recognize the funded or unfunded status of our defined benefit plans as an asset or liability in our consolidated balance sheet and recog nize changes in the funded status in the year in which the changes occur in accumulated other comprehensive income (loss). In addition to the defined benefit plans it sponsors, NBCUniversal is also obligated to reimburse GE for future benefit payments to t hose participants who were vested in the supplemental pension plan sponsored by GE at the time of the NBCUniversal transaction in 2011.
Income Taxes	We base our provision for income taxes on our current period income, changes in our deferred income tax assets and liabilities, income tax rates, changes in estimates of our uncertain tax positions, and tax planning opportunities available in the jurisdictions in which we operate. We recognize deferred tax assets and liabilities when there are temporary differences between the financial reporting basis and tax basis of our assets and liabilities and for the expected benefits of using net operating loss carryforwards . When a change in the tax rate or tax law has an impact on deferred taxes, we apply the change based on the years in which the temporary differences are expected to reverse. We record the change in our consolidated financial statements i n the period of enactment. The determination of the income tax consequences of a business combination includes identifying the tax basis of assets and liabilities acquired and any contingencies associated with uncertain tax positions assumed or resulting from the business combination. Deferred tax assets and liabilities related to temporary differences of an acquired entity are recorded as of the date of the business combination and are based on our estimate of the ultimate tax basis that will be accepted by the various tax authorities. We record liabilities for contingencies associated with prior tax returns filed by the acquired entity based on criteria set forth in the appropriate accounting guidance. We adjust the deferred tax accounts and the liabiliti es periodically to reflect any revised estimated tax basis and any estimated settlements with the various tax authorities. The effects of these adjustments are recorded to income tax expense. From time to time, we engage in transactions in which the tax co nsequences may be subject to uncertainty. In these cases, we evaluate our tax positions using the recognition threshold and the measurement attribute in accordance with the accounting guidance related to uncertain tax positions. Examples of these transacti ons include business acquisitions and dispositions , including consideration paid or received in connection with these transactions, certain financing transactions , and the allocation of inc ome among state and local tax jurisdictions . Significant judgment i s required in assessing and estimating the tax consequences of these transactions. We determine whether it is more likely than not that a tax position will be sustained on examination, including the resolution of any related appeals or litigation processes , based on the technical merits of the position. A tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to be recognized in our consolidated financial statements. We classify interest and pen alties, if any, associated with our uncertain tax positions as a component of income tax expense.
Derivative Financial Instruments	Derivative Financial Instruments We use derivative financial instruments to manage our exposure to the risks associated with fluctuations in interest rates, foreign e xchange rates and equity prices. Our objective is to manage the financial and operational exposure arising from these risks by offsetting gains and losses on the underlying exposures with gains and losses on the derivatives used to economically hedge them. Our derivative financial instruments are recorded in our consolidated balance sheet at fair value. The impact of our derivative financial instruments on our consolidated financial statements was not material for all periods presented. The derivative component of the prepaid forward sale agreements were equity derivative financial instruments embedded in the related contracts, which we used to manage our exp osure to and benefits from price fluctuations in the common stock of the related investments. For these derivative financial instruments, we separated the derivative component from the host contract and recorded in each period the change in its value to in vestment income (loss), net.
Earnings Per Share Policy	Diluted earnings per common share attributable to Comcast Corporation shareholders (“diluted EPS”) considers the impact of potentially dilutive securities using the treasury stock method. Our potentially dilutive securities include potential common shares related to our stock options and our res tricted share units (“RSUs”). Diluted EPS excludes the impact of potential common shares related to our stock options in periods in which the combination of the option exercise price and the associated unrecognized compensation expense is greater than the average market price of our common stock . The amount of potential common shares related to our share-based compensation plans that were excluded from dilu ted EPS because their effect would have been antidilutive was not material for 2015 , 2014 and 2013 .
Fair Value Of Financial Instruments	The accounting guidance related to financial assets and financial liabilities (“financial instruments”) establishes a hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques (market approach, income approach and cost approach). The levels of the hierarchy are described below. Level 1: Consists of financial instruments whose values are based on quoted market prices for identical financial instruments in an active market. Level 2: Consists of financial instruments that are valued using models or other valuation methodologies. These models use inputs that are observable either directly or indirectly. Level 2 inputs include (1) quoted prices for similar assets or liabilities in active markets, (2) quoted prices for identical or similar assets or liabilities in markets that are not active, (3) pricing models whose inputs are observable for substantially the full term of the financial instrument and (4) pricing models whose inputs are derived primarily from or corroborated by observable market data through correlation or other means for substantially the full term of the financial instrument. Level 3: Consists of financial instruments whose values are determined using pricing models that use significant inputs that are primarily unobservable, discounted cash flow methodologies or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of financial instruments and their classification within the fair value hierarchy. Financial instruments are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. There have been no changes in the classification of any financial instruments within the fair value hierarchy in the periods presented. Our financial instruments that are accounted for at fair value on a recurring basis are presented in the table below.
NBCUniversal Media LLC [Member]
Basis of Presentation	The accompanying consolidated financial statements include all entities in which we have a controlling voting interest and variable interest entities (“VIEs”) require d to be consolidated in accordance with generally accepted accounting principles in the United States (“GAAP”). Transactions between NBCUniversal and both Comcast and Comcast’s consolidated subsidiaries are reflected in these consolidated financial stateme nts and disclosed as related party transactions when material.
Foreign Currency Translation	We translate assets and liabilities of our foreign operations where the functional currency is the local currency, primarily the euro, British pound , and Japanese yen, into U.S. dollars at the e xchange rate as of the balance sheet date and translate revenue and expenses using average monthly exchange rates . The related translation adjustments are recorded as a component of accumulated other comprehensive income (loss). Any foreign currency transa ction gains and losses are included in our consolidated statement of income.
Cash Equivalents	Cash Equivalents The carrying amounts of our cash equivalents approximate their fair values. Our cash equivalents consist primarily of money market funds and U.S. government obligations, as well as commercial paper and certificates of deposit with maturities of three months or less when purchased.
Use of Estimates	Our consolidated financial statements are prepared in accordance with GAAP, which requires us to select accounting policies, including in certain cases industry-specific policies, and make estimates that affect the reported amount of assets, liabilities, revenue and expenses, and the related disclosure of contingent assets and contingent liabilities. Actual results could differ from these estimates. We believe that the judgments and related estimates for the followin g items are critical in the preparation of our consolidated financial statements: revenue recognition (see below) film and television costs (see Note 6 ) goodwill and intangible assets (see Note 9 ) In addition, the following accounting policies are specific to the industries in which we operate: capitalization and amortization of film and television costs (see Note 6 ) Information on our other accounting policies and methods that are used in the preparation of our consolidated financial statements are included, where applicable, in their respective footnotes that follow. Below is a discussion of accounting policies and methods used in our consolidated financial statements that are not presented within other footnotes.
Film And Television Costs	Capitalization of Film and Television Costs We capitalize film and television production costs, including direct costs, production overhead, print costs, development costs and interest. We amortize capitalized film and tele vision production costs, including acquired libraries, and accrue costs associated with participation and residual payments to programming and production expense s . We generally record the amortization and the accrued costs using the individual film forecas t computation method, which amortizes such costs in the same ratio as the associated ultimate revenue. Estimates of ultimate revenue and total costs are based on anticipated release patterns, public acceptance and historical results for similar productions . Unamortized film and television costs, including acquired film and television libraries, are stated at the lower of unamortized cost or fair value. We do not capitalize costs related to the distrib ution of a film in movie theaters or the licensing or sal e of a film or television production, which are primarily costs associated with the marketing and distribution of film and television programming. In determining the estimated lives and method of amortization of acquired film and television libraries, we generally use the method and the life that most closely follow the undiscounted cash flows over the estimated life of the asset. Upon the occurrence of an event or a change in circumstance that was known or knowable as of the balance sheet date and that i ndicates the fair value of a film is less than its unamortized costs, we determine the fair value of the film and record an impairment charge for the amount by which the unamortized capitalized costs exceed the film’s fair value. We enter into cofinancin g arrangements with third parties to jointly finance or distribute certain of our film productions. Cofinancing arrangements can take various forms, but in most cases involve the grant of an economic interest in a film to an investor. The number of investo rs and the terms of these arrangements can vary, although investors generally assume full risk for the portion of the film acquired in these arrangements. We account for the proceeds received from a third-party investor under these arrangements as a reduct ion to our capitalized film costs. In these arrangements, the investor owns an undivided copyright interest in the film, and therefore in each period we record either a charge or a benefit to programming and production expenses to reflect the estimate of t he third-party investor’s interest in the profit or loss of the film. The estimate of the third-party investor’s interest in the profit or loss of a film is determined using the ratio of actual revenue earned to date to the ultimate revenue expected to be recognized over the film’s useful life. We capitalize the costs of programming content that we license but do not own, including rights to multiyear , live-event sports programming, at the earlier of when payments are made for the programming or when the li cense period begins and the content is available for use. We amortize capitalized programming costs as the associated programs are broadcast. We amortize multiyear, live-event sports programming rights using the ratio of the current period revenue to the estimated u ltimate r evenue or under the terms of the contract . Acquired programming costs are recorded at the lower of unamortized cost or net realizable value on a program by program, package, channel or daypart basis. A daypart is an aggregation of programs broadc ast during a particular time of day or progr ams of a similar type. P rogramming acquired by our Cable Networks segment is primarily tested on a channel basis for impairment, whereas programming acquired by our Broadcast Television segment is tested on a daypart basis. If we determine that the estimates of future cash flows are insufficient or if there is no plan to broadcast certain programming, we recognize an impairment charge to programming and production expense s .
Investments	Equity Method We use the equity method to account for investments in which we have the ability to exercise significant influence over the investee’s operating and financial policies or where we hold significant partnership or LLC interests . Equity method investments are recorded at cost and are adjusted to recognize ( 1 ) our proportionate share of the investee’s net income or loss after the date of investment, ( 2 ) amortization of the recorded investment that exceeds our share of the book value of the invest ee’s net assets, ( 3 ) additional contributions made and dividends received, and ( 4 ) impairments resulting from other-than-temporary declines in fair value. Gains or losses on the sale of equity method investments are recorded to other income (expense), net. If an equity method investee were to issue additional securities that would change our proportionate share of the entity, we would recognize the change, if any, as a gain or loss in our consolidated statement of income. Cost Method We use the cost method to account for investments not accounted for under the fair value method or the equity method. Impairment Testing of Inve stments We review our investment portfolio each reporting period to determine whether there are identified events or circumstances that would indicate there is a decline in the fair value that would be considered other than temporary. For our nonpublic inv estments, if there are no identified events or circumstances that would have a significant adverse effect on the fair value of the investment, then the fair value is not estimated. If an investment is deemed to have experienced an other-than-temporary decl ine below its cost basis, we reduce the carrying amount of the investment to its quoted or estimated fair value, as applicable, and establish a new cost basis for the investment. For our available-for-sale securities and cost method investments, we record the impairment to investme nt income (loss), net. For our equity method investments, we record the impairment to other income (expense), net.
Property and Equipment	Property and equipment are stated at cost. We capitalize improvements that extend asset lives and expense repairs and maintenance costs as incurred. We record depreciation using the straight-line method over the asset’s estimated useful life. For assets that are sold or retired, we remove the applicable cost and accumulated depreciation and, unless the gain or loss on disposition is presented separately, we recognize it as a component of depreciation expense. We evaluate the recoverability of our propert y and equipment whenever events or substantive changes in circumstances indicate that the carrying amount may not be recoverable. The evaluation is based on the cash flows generated by the underlying asset groups, including estimated future operating resul ts, trends or other determinants of fair value. If the total of the expected future undiscounted cash flows were less than the carrying amount of the asset group, we would recognize an impairment charge to the extent the carrying amount of the asset group exceeded its estimated fair value. Unless presented separately, the impairment charge is included as a component of depreciation expense.
Goodwill and Intangible Assets	We assess the recoverability of our goodwill annually, or more frequently whenever events or substantive changes in circumstances indicate that the carrying amount of a reporting unit may exceed its fair value. We test goodwill for impairment at the reporting unit level. To determine our reporting units, we evaluate the components one l evel below the segment level and we aggregate the components if they have similar economic characteristics. As a result of this assessment, our reporting units are the same as our four reportable segments. We evaluate the determination of our reporting uni ts used to test for impairment periodically or whenever events or substantive changes in circumstances occur. The assessment of recoverability may first consider qualitative factors to determine whether the existence of events or circumstances leads to a d etermination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. A quantitative assessment is performed if the qualitative assessment results in a more-likely-than-not determination or if a qualitative assessment is not performed. The quantitative assessment considers if the carrying amount of a reporting unit exceeds its fair value, in which case an impairment charge is recorded to the extent the carrying amount of the reporting unit’s goodwill exceeds its implied fair value. Unless presented separately, the impairment charge is included as a component of amortization expense. Indefinite-Lived Intangible Assets Indefinite-lived intangible assets consist of trade names and FCC licenses. We assess the recoverability of our indefinite-lived intangible assets annually, or more frequently whenever events or substantive changes in circumstances indicate that the assets might be impaired. We evaluate the unit of account used to test for impairm ent of our indefinite-lived intangible assets periodically or whenever events or substantive changes in circumstances occur to ensure impairment testing is performed at an appropriate level. The assessment of recoverability may first consider qualitative f actors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount. A quantitative assessment is performed if the qualitati ve assessment results in a more-likely-than- not dete rmination or if a qualitative assessment is not performed. When performing a quantitative assessment, we estimate the fair value of our indefinite-lived intangible assets primarily based on a discounted cash flow analysis that involves significant judgment . When analyzing the fair values indicated under the discounted cash flow models, we also consider multiples of operating income before depreciation and amortization generated by the underlying assets, current market transactions, and profitability informa tion. If the fair value of our indefinite-lived intangible assets were less than the carrying amount, we would recognize an impairment charge for the difference betw een the estimated fair value and t he carrying value of the assets . Unless presented separat ely, the impairment charge is included as a component of amortization expense. We did not recognize any material impairment charges in any of the periods presented . F inite-Lived Intangible Assets Finite-lived intangible assets are subject to amortization and consist primarily of customer relationships acquired in business combinations, intellectual property rights and software. Our finite-lived intangible assets are amortized primarily on a straight-line basis over their estimated useful life or the term of t he associated agreement. We capitalize direct development costs associated with internal-use software, including external direct costs of material and services and payroll costs for employees devoting time to these software projects. We also capitalize cos ts associated with the purchase of software licenses. We include these costs in intangible assets and generally amortize them on a straight-line basis over a period not to exceed five years. We expense maintenance and training costs, as well as costs incurred during the preliminary stage of a project, as they are incurred. We capitalize initial operating system software costs and amortize them over the life of the associated hardware. We evaluate the recoverability of our finite-lived intangible assets whenever events or substantive changes in circumstances indicate that the carrying amount may not be recoverable. The evaluation is based on the cash flows generated by the underlying asset groups, including estimated future operating results, trends or other determinant s of fair value. If the total of the expected future undiscounted cash flows were less than the carrying amount of the asset group, we would recognize an impairment charge to the extent the carrying amount of the asset group exceed ed its estimated fair val ue. Unless presented separately, the impairment charge is included as a component of amortization expense.
Revenue Recognition	Revenue R ecognition Cable Networks and Broadcast Television Segments Our Cable Networks segment generates revenue primarily from the distribution of our cable network programming to multichannel video providers, from the sale of advertising on our cable networks an d related digital media properties, from the licensing of our owned programming through various distribution platforms, from the sale of our owned programming through digital distribution services such as iTunes, and from the programming our cable producti on studio sells to third-party networks and subscription video on demand services. Our Broadcast Television segment generates revenue primarily from the sale of advertising on our broadcast networks, owned local broadcast television stations and related di gital media properties, from the licensing of our owned programming through various distribution platforms, including to cable and broadcast networks, from the fees received under retransmission consent agreements and from the programming our broadcast tel evision production studio sells to third-party networks and subscription video on demand services. We recognize revenue from distributors as programming is provided, generally under multiyear distribution agreements. From time to time, the distribution agr eements expire while programming continues to be provided to the distributor based on interim arrangements while the parties negotiate new contract terms. Revenue recognition is generally limited to current payments being made by the distributor, typically under the prior contract terms, until a new contract is negotiated, sometimes with effective dates that affect prior periods. Differences between actual amounts determined upon resolution of negotiations and amounts recorded during these interim arrangeme nts are recorded in the period of resolution. Advertising revenue for our Cable Networks and Broadcast Television segments is recognized in the period in which commercials are aired or viewed. In some instances, we guarantee audience ratings for the commer cials. To the extent there is a shortfall in the ratings that were guaranteed, a portion of the revenue is deferred until the shortfall is settled, primarily by providing additional advertising units. We recognize revenue from the licensing of our owned pr ogramming and programming produced by our studios for third parties when the content is available for use by the licensee, and when certain other conditions are met. When license fees include advertising time, we recognize the component of revenue associat ed with the advertisements when they are aired or viewed. Filmed Entertainment Segment Our Filmed Entertainment segment generates revenue primarily from the worldwide distribution of our produced and acquired films for exhibition in movie theaters, from the licensing of our owned and acquired films through various distribution platforms, and from the sale of our owned and acquired films on standard-definition video discs and Blu-ray discs (together, “DVDs”) and through digital distribution services. Our F ilmed Entertainment segment also generates revenue from producing and licensing live stage plays, from the distribution of filmed entertainment produced by third parties, and from Fandango, our movie ticketing and entertainment business. We recognize reven ue from the distribution of films to movie theaters when the films are exhibited. We recognize revenue from the licensing of a film when the film is available for use by the licensee, and when certain other conditions are met. We recognize revenue from DVD sales, net of estimated returns and customer incentives, on the date that DVDs are delivered to and made available for sale by retailers. Theme Parks Segment Our Theme Parks segment generates revenue primarily from ticket sales and guest spending at our Universal theme parks in Orlando, Florida; Hollywood, California; and, as of November 2015, Osaka, Japan, as well as from licensing and other fees. We recognize revenue from advance theme park ticket sales when the tickets are used. For annual passes, we recognize revenue on a straight-line basis over the period following the activation date.
Advertising Expenses	Advertising Expenses Advertising costs are expensed as incurred.
Share-Based Compensation	Comcast maintains share-based compensation plans that prima rily consist of awards of RSUs and stock options to certain employees and directors as part of its approach to long-term incentive compensation. Awards generally vest over a period of 5 years and in the case of stock options, have a 10 year term. Additiona lly, through its employee stock purchase plans, employees are able to purchase shares of Comcast common stock at a discount through payroll deductions. Certain of our employees participate in these plans and the expense associated with their participation is settled in cash with Comcast. The cost associated with Comcast’s share-based compensation is based on an award’s estimated fair value at the date of grant and is recognized over the period in which any related services are provided. RSUs are valued base d on the closing price of Comcast common stock on the date of grant and are discounted for the lack of dividends, if any, during the vesting period. Comcast uses the Black-Scholes option pricing model to estimate the fair value of stock option awards.
Postretirement and Pension Benefits	All of our postretirement benefit plans are unfunded and substantially all of our postretirement benefit obligations are r ecorded to noncurrent liabilities. The expense we recognize for our postretirement benefit plans is determined using certain assumptions, including the discount rate . Pension Plans We sponsor various qualified and nonqualified defined benefit plans for dom estic employees for which future benefits have been frozen since the beginning of 2013, therefore we did not recognize service costs related to our pension plans for the periods presented . The expense we recognize for our defined benefit plans is determined using certain assumptions, including the discount rate and the expected long-term rate of return on plan assets. We recognize the funded or unfunded status of our defined benefit plans as an asset or liability in our consolidated balance sheet and recognize changes in the funded status in the year in whi ch the changes occur in accumulated other comprehensive income (loss). In addition to the defined benefit plans we sponsor, we are also obligated to reimburse GE for future benefit payments to those participants who were vested in the supplemental pension plan sponsored by GE at the time of the joint venture transaction .
Derivative Financial Instruments	Derivative Financial Instruments We use derivative fin ancial instruments to manage our exposure to the risks associated with fluctuations in foreign exchange rates and interest rates. Our objective is to manage the financial and operational exposure arising from these risks by offsetting gains and losses on t he underlying exposures with gains and losses on the derivatives used to economically hedge them. Our derivative financial instruments are recorded in our consolidated balance sheet at fair value. The impact of our derivative financial instruments on our c onsolidated financial statements was not material for all periods presented.
Fair Value Of Financial Instruments	The accounting guidance related to financial assets and financial liabilities (“financial instruments”) establishes a hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques (market approach, income approach and cost approach). Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of financial instruments and their clas sification within the fair value hierarchy. Our financial instruments that are accounted for at fair value on a recurring basis were not material for all periods presented
