Basis of Presentation and Summary of Significant Accounting Policies | 1 ) BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business —ViacomCBS Inc. is comprised of the following segments: TV Entertainment (CBS Television Network, CBS Television Studios, CBS Television Distribution, CBS Interactive, CBS Sports Network, CBS Television Stations and CBS-branded streaming services), Cable Networks (Showtime Networks, Nickelodeon, MTV, BET, Comedy Central, Paramount Network, Nick Jr., VH1, TV Land, CMT, Pop TV, Smithsonian Networks, ViacomCBS Networks International, Network 10, Channel 5, Telefe and Pluto TV), Filmed Entertainment (Paramount Pictures, Paramount Players, Paramount Animation and Paramount Television Studios); and Publishing (Simon & Schuster). References to “ViacomCBS”, the “Company”, “we”, “us” and “our” refer to ViacomCBS Inc. and its consolidated subsidiaries, unless the context otherwise requires. Merger with Viacom Inc. —On December 4, 2019, Viacom Inc. (“Viacom”) merged with and into CBS Corporation (“CBS”), with CBS continuing as the surviving company (the “Merger”). At the effective time of the Merger (the “Effective Time”), the combined company changed its name to ViacomCBS Inc. (“ViacomCBS”). At the Effective Time, (1) each share of Viacom Class A Common Stock issued and outstanding immediately prior to the Effective Time, other than shares held directly by Viacom as treasury shares or held by CBS, was converted automatically into 0.59625 shares of ViacomCBS Class A Common Stock, and (2) each share of Viacom Class B Common Stock issued and outstanding immediately prior to the Effective Time, other than shares held directly by Viacom as treasury shares or held by CBS, was converted automatically into 0.59625 shares of ViacomCBS Class B Common Stock (together with ViacomCBS Class A Common Stock, the “ViacomCBS Common Stock”). At the Effective Time, each share of CBS Class A Common Stock and each share of CBS Class B Common Stock (together with CBS Class A Common Stock, the “CBS Common Stock”) issued and outstanding immediately prior to the Effective Time, remained an issued and outstanding share of ViacomCBS Class A Common Stock and ViacomCBS Class B Common Stock, respectively, and was not affected by the Merger. Following the Merger, the CBS Common Stock was delisted from the New York Stock Exchange and the Viacom Common Stock ceased trading on the Nasdaq Stock Market LLC (“Nasdaq”). On December 5, 2019, ViacomCBS Class A Common Stock and ViacomCBS Class B Common Stock were listed on Nasdaq and began trading under the ticker symbols VIACA and VIAC, respectively. Change in Reporting Entity — The Merger has been accounted for as a transaction between entities under common control as National Amusements, Inc. (“NAI”) was the controlling stockholder of each of CBS and Viacom (and remains the controlling stockholder of ViacomCBS). Upon the closing of the Merger, the net assets of Viacom were combined with those of CBS at their historical carrying amounts and the companies have been presented on a combined basis for all periods presented in the consolidated financial statements. This presentation constitutes a change in reporting entity. The following table provides the impact of the change in reporting entity on our results of operations for periods prior to the Merger. Period from January 1 Year Ended December 31, to December 4, 2019 2018 2017 Net earnings from continuing operations attributable to ViacomCBS $ 1,353 $ 1,463 $ 1,959 Net earnings per common share from continuing operations attributable to ViacomCBS: Basic $ .44 $ .35 $ 1.85 Diluted $ .45 $ .37 $ 1.83 Other comprehensive income (loss) $ (148 ) $ (202 ) $ 190 Discontinued Operations —On November 16, 2017, we completed the disposition of CBS Radio Inc. (“CBS Radio”) through a split-off. CBS Radio has been presented as a discontinued operation in our consolidated financial statements (see Note 18 ). Also included in discontinued operations are liabilities associated with indemnification obligations for leases primarily associated with the previously discontinued operations of Famous Players Inc. Principles of Consolidation —The consolidated financial statements include the accounts of ViacomCBS, its subsidiaries in which a controlling interest is maintained and variable interest entities (“VIEs”) where we are considered the primary beneficiary, after the elimination of intercompany accounts and transactions. Controlling interest is determined by majority ownership interest and the absence of substantive third party participating rights. Investments over which we have a significant influence, without a controlling interest, are accounted for under the equity method. Our proportionate share of net earnings or loss of the entity is recorded in “Equity in earnings (loss) of investee companies, net of tax” on the Consolidated Statements of Operations. Use of Estimates —The preparation of our financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities as of the date of the financial statements, and the reported amount of revenues and expenses during the periods presented. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may vary from these estimates under different assumptions or conditions. Business Combinations —We generally account for business combinations using the acquisition method of accounting. Under the acquisition method, once control is obtained of a business, 100% of the assets, liabilities and certain contingent liabilities acquired, as well as amounts attributed to noncontrolling interests, are recorded at fair value. Any transaction costs are expensed as incurred. The Merger was accounted for as a transaction between entities under common control as NAI was the controlling stockholder of each of CBS and Viacom. Cash and Cash Equivalents —Cash and cash equivalents consist of cash on hand and highly liquid investments with maturities of three months or less at the date of purchase, including money market funds, commercial paper and bank time deposits. At December 31, 2019 and 2018 , we had restricted cash of $202 million and $120 million , respectively, consisting of amounts held in grantor trusts related to agreements with former executives. Restricted cash is included within “Other current assets” and “Other assets” on the Consolidated Balance Sheets. Programming Inventory —We acquire rights to programming and produce programming to exhibit on our broadcast and cable networks, on our broadcast television stations, direct to consumers through our digital streaming services, and in theaters. We also produce programming for third parties. Internally-Produced Programming —Costs incurred to produce television programs and feature films (which include direct production costs, production overhead, acquisition costs and development costs) are capitalized when incurred. We use an individual-film-forecast-computation method to amortize capitalized production costs and to accrue estimated liabilities for residuals and participations over the applicable title’s life cycle based upon the ratio of current period revenues to estimated remaining total gross revenues to be earned (“Ultimate Revenues”) for each title. The estimate of Ultimate Revenues impacts the timing of amortization and accrual of residuals and participations. For television programming, Ultimate Revenue estimates are initially limited to the amount of revenue contracted for each episode in the initial market and estimates of revenue from a secondary market where we can demonstrate a history of earning such revenue in that market. Television programming costs and participation costs incurred in excess of such amounts are expensed as incurred on an episode by episode basis. Estimates for additional secondary market revenues such as domestic and foreign syndication and home entertainment are included in the estimated lifetime revenues once it can be demonstrated that a program can be successfully licensed in such secondary market. For each television program, management bases these estimates on the performance in the initial markets, the existence of future firm commitments to sell and the past performance of similar television programs. Television programming costs incurred subsequent to the establishment of the secondary market are initially capitalized and amortized, and estimated liabilities for participations are accrued, based on the proportion that current period revenues bear to the estimated remaining total lifetime revenues. For feature films, our estimate of Ultimate Revenues includes revenues from all sources that are estimated to be earned within 10 years from the date of a film’s initial theatrical release. Prior to the release of feature films, we estimate Ultimate Revenues based on the historical performance of similar content and pre-release market research (including test market screenings), as well as factors relating to the specific film, including the expected number of theaters and markets in which the original content will be released, the genre of the original content and the past box office performance of the lead actors and actresses. Upon a film’s initial release, we update our estimate of Ultimate Revenues based on actual and expected future performance. Our estimates of revenues from succeeding windows and markets are revised based on historical relationships to theatrical performance and an analysis of current market trends. For acquired film libraries, our estimate of Ultimate Revenues is for a period within 20 years from the date of acquisition. Ultimate Revenue estimates are periodically reviewed and adjustments, if any, will result in changes to inventory amortization rates and estimated accruals for residuals and participations. An impairment charge is recorded if the fair value of a television program or feature film falls below the unamortized production costs. Film development costs that have not been set for production are expensed within three years unless they are abandoned earlier, in which case these projects are written down to their estimated fair value in the period the decision to abandon the project is determined. Acquired Programming Rights —Costs incurred in acquiring program rights, including advances, are capitalized when the license period has begun and the program is accepted and available for airing. These costs are amortized over the shorter of the license period or the period in which an economic benefit is expected to be derived based on the timing of our usage of and benefit from such programming. The net realizable value of acquired programming rights is regularly evaluated by us either by title or on a daypart basis, which is defined as an aggregation of programs broadcast during a particular time of day or an aggregation of programs of a similar type based on the specific demographic targeted by each respective program or program service. Net realizable value is determined by estimating advertising revenues to be derived from the future airing of the programming and allocating affiliate revenue to the programming, each as applicable. An impairment charge is recorded if our estimates of future cash flows are below the carrying amount of the programming or if programming is abandoned. The costs of programming rights licensed under multi-year sports programming agreements are capitalized if the rights payments are made before the related economic benefit has been received. These costs are expensed over the period in which an economic benefit is expected to be derived based on the relative value of the events broadcast by us during a period. The relative value for an event is determined based on the revenues generated for that event in relation to the estimated total revenues over the remaining term of the sports programming agreement. The estimated economic benefit for acquired programming, including revenue projections for multi-year sports programming, are periodically reviewed. Adjustments, if any, will result in changes to amortization rates and could result in future net realizable value adjustments. Television and feature film programming and production costs, including inventory amortization, development costs, residuals and participations and impairment charges, if any, are included within “Operating expenses” in the Consolidated Statements of Operations. Property and Equipment —Property and equipment is stated at cost. Depreciation is calculated using the straight-line method over estimated useful lives as follows: Buildings and building improvements 10 to 40 years Leasehold improvements Shorter of lease term or useful life Equipment and other (including finance leases) 3 to 20 years Costs associated with repairs and maintenance of property and equipment are expensed as incurred. Impairment of Long-Lived Assets —The Company assesses long-lived assets and intangible assets, other than goodwill and intangible assets with indefinite lives, for impairment whenever there is an indication that the carrying amount of the asset may not be recoverable. Recoverability of these assets is determined by comparing the forecasted undiscounted cash flows expected to be generated by these assets to their net carrying value. If the carrying value is not recoverable, the amount of impairment charge, if any, is measured by the difference between the net carrying value and the estimated fair value of the asset. Investments —Investments over which we have a significant influence, without a controlling interest, are accounted for under the equity method. Investments for which we have no significant influence are measured at fair value where a readily determinable fair value exists. Investments that do not have a readily determinable fair value are measured at cost less impairment, if any, and adjusted for observable price changes. Gains and losses resulting from changes in the fair value of equity investments are recorded in the Consolidated Statements of Operations. Prior to the adoption of new Financial Accounting Standards Board (“FASB”) guidance in 2018, we recorded unrealized gains and losses on publicly traded equity investments in other comprehensive income. We monitor our investments for impairment and reduce the carrying value of the investment if we determine that an impairment charge is required based on qualitative and quantitative information. Our investments are included in “Other assets” on the Consolidated Balance Sheets. Goodwill and Intangible Assets —Goodwill is allocated to various reporting units, which are at or one level below our operating segments. Intangible assets with finite lives, which primarily consist of trade names, licenses, and customer agreements are generally amortized using the straight-line method over their estimated useful lives, which range from 4 to 40 years. Goodwill and other intangible assets with indefinite lives, which consist primarily of FCC licenses in the U.S. and broadcast licenses in Australia, are not amortized but are tested for impairment on an annual basis and between annual tests if events occur or circumstances change that would more likely than not reduce the fair value below its carrying amount. If the carrying value of goodwill or the indefinite-lived intangible asset exceeds its fair value, an impairment charge is recognized (see Note 4 ). Guarantees —At the inception of a guarantee, we recognize a liability for the fair value of an obligation assumed by issuing the guarantee. The related liability is subsequently reduced as utilized or extinguished and increased if there is a probable loss associated with the guarantee which exceeds the value of the recorded liability. Treasury Stock —Treasury stock is accounted for using the cost method. Retirements of treasury stock are reflected as a reduction to additional paid-in capital. Fair Value Measurements —Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The framework for measuring fair value provides a hierarchy that prioritizes the inputs to valuation techniques used in measuring fair value. Level 1 is based on publicly quoted prices for the asset or liability in active markets. Level 2 is based on inputs that are observable other than quoted market prices in active markets, such as quoted prices for the asset or liability in inactive markets or quoted prices for similar assets or liabilities. Level 3 is based on unobservable inputs reflecting our own assumptions about the assumptions that market participants would use in pricing the asset or liability. Certain assets and liabilities, including foreign currency hedges and deferred compensation liabilities, are measured and recorded at fair value on a recurring basis. Film and television production costs, goodwill, intangible assets, and equity method investments are recorded at fair value only if an impairment charge is recognized. Impairment charges, if applicable, are determined using discounted cash flows, which is a Level 3 valuation technique. Derivative Financial Instruments —Derivative financial instruments are recorded on the Consolidated Balance Sheets as assets or liabilities and measured at fair value. For derivatives designated as hedges of the fair value of assets or liabilities, the changes in fair value of both the derivatives and the hedged items are recorded in “Other items, net” in the Consolidated Statements of Operations. For derivatives designated as cash flow hedges, the effective portion of the changes in fair value of the derivatives is recorded in “Accumulated other comprehensive loss ” on the Consolidated Balance Sheets and subsequently recognized in net earnings. Pension and Postretirement Benefits —The service cost component of net benefit cost for our pension and postretirement benefits is recorded on the same line items in the Consolidated Statements of Operations as other compensation costs of the related employees. All of the other components of net benefit cost are presented separately from the service cost component and below the subtotal of operating income in “Other items, net” or “Pension settlement charge” in the Consolidated Statements of Operations. Other Liabilities —Other liabilities consist primarily of the noncurrent portion of residual liabilities of previously disposed businesses, long-term income tax liabilities, deferred compensation and other employee benefit accruals. Revenues Revenue is recognized when control of a good or service is transferred to a customer. Control is considered to be transferred when the customer has the ability to direct the use of and obtain substantially all of the remaining benefits of that good or service. Advertising Revenues —Advertising revenues are recognized when the advertising spots are aired on television or displayed on digital platforms. Advertising spots are typically sold as part of advertising campaigns consisting of multiple commercial units. If a contract includes a guarantee to deliver a targeted audience rating or number of impressions, the delivery of the advertising spots that achieve the guarantee represents the performance obligation to be satisfied over time and revenues are recognized based on the proportion of the audience rating or impressions delivered to the total guaranteed in the contract. Audience ratings and impressions are determined based on data provided by independent third-party companies. To the extent the amounts billed exceed the amount of revenue recognized, such excess is deferred until the guaranteed audience ratings or impressions are delivered. For contracts that do not include impressions guarantees, the individual advertising spots are the performance obligation and consideration is allocated among the individual advertising spots based on relative standalone selling price. Advertising contracts, which are generally short-term, are billed monthly, with payments due shortly after the invoice date. Advertising revenues are generated by the TV Entertainment and Cable Networks segments. Affiliate Revenues —Affiliate revenues primarily consist of fees received from multichannel video programming distributors (“MVPDs”) and third-party live television digital streaming offerings (“virtual MVPDs”) for carriage of our cable networks (“cable affiliate fees”) and television stations (“retransmission fees”); fees from television stations affiliated with the CBS Television Network (“station affiliation fees”); and subscription fees for our digital streaming subscription offerings, including CBS All Access , the Showtime streaming subscription offering (“Showtime OTT”) and BET+. Costs incurred for advertising, marketing and other services provided to us by cable, satellite and other distributors that are in exchange for a distinct service are recorded as expenses. If a distinct service is not received, such costs are recorded as a reduction to revenues. The performance obligation for our affiliate agreements is a license to our programming provided through the continuous delivery of live linear feeds and, for agreements with MVPDs and subscribers to our digital streaming services, also includes a license to programming for video-on-demand viewing. Affiliate revenues are recognized over the term of the agreement as we satisfy our performance obligation by continuously providing our customer with the right to use our programming. For agreements that provide for a variable fee, revenues are determined each month based on an agreed upon contractual rate applied to the number of subscribers to our customer’s service. For agreements that provide for a fixed fee, revenues are recognized based on the relative fair value of the content provided over the term of the agreement. These agreements primarily include agreements with television stations affiliated with the CBS Television Network (“network affiliates”) for which fair value is determined based on the fair value of the network affiliate’s service and the value of our programming. For affiliate revenues, payments are generally due monthly. Affiliate revenues are generated by the TV Entertainment and Cable Networks segments. Content Licensing Revenues —Content licensing revenues are generated from the licensing of exhibition rights for our internally-produced television and film programming to television stations, cable networks and subscription streaming services; licensing of our content for distribution on transactional video-on-demand services; the distribution of our content through DVD and Blu-ray disc sales to wholesale and retail partners; the use of our trademarks and brands for consumer products, recreation and live events; and fees from the distribution of third-party programming. For licenses of exhibition rights for internally-produced programming, each individual episode or film delivered represents a separate performance obligation and revenues are recognized when the episode or film is made available to the licensee for exhibition and the license period has begun. For license agreements that include delivery of content on one or more dates for a fixed fee, consideration is allocated based on the relative standalone selling price of each episode or film. Estimation of standalone selling prices requires judgment, which can impact the timing of recognizing revenues. Agreements to license programming are often long term, with collection terms ranging from one to five years. When payment is due from a customer more than one year before or after revenue is recognized, we consider the contract to contain a significant financing component and the transaction price is adjusted for the effects of the time value of money. We do not adjust the transaction price for the time value of money if payment is expected within one year of recognizing revenues. We also license our programming to distributors of transactional video-on-demand and similar services. Under these arrangements, our performance obligation is the delivery of our content to such distributors who then license our content to the end customer. Our revenues are determined each month based on a contractual rate applied to the number of licenses to the distributors’ end customers. Similarly, revenues earned from electronic sell-through services are recognized as each program is downloaded by the end customer. Revenues associated with the licensing of our brands for consumer products, recreation and live events are generally determined based on contractual royalty rates applied to sales reported by the licensees. For consumer products and recreation arrangements that include minimum guaranteed consideration, revenue is recognized as sales occur by the licensee, if the sales-based consideration is expected to exceed the minimum guarantee, or ratably if it is not expected to exceed the minimum guarantee. For live events, we recognize revenue when the event is held. Revenues from the sales of DVDs and Blu-ray discs to wholesalers and retailers are recognized upon the later of the physical delivery to the customer or the date that any sales restrictions on the retailers are lifted. We earn revenues from the distribution of content on behalf of third parties. We also have arrangements for the distribution or sale of our content by third parties. Under such arrangements, we determine whether revenues should be recognized based on the gross amount of consideration received from the customer or the net amount of revenue we retain after payment to the third party producer or distributor, based on an assessment of which party controls the good or service being transferred. Content licensing revenues are generated by the TV Entertainment , Cable Networks and Filmed Entertainment segments. Theatrical Revenues —Theatrical revenue is earned from the theatrical distribution of our films during the exhibition period. Under these arrangements, revenues are recognized based on sales to the end customer. Theatrical revenues are generated by the Filmed Entertainment segment. Publishing —Publishing revenues are recognized when merchandise is shipped or electronically delivered to the consumer. Payments for publishing revenues are due shortly after shipment or electronic delivery. Revenue Allowances —Print books, DVDs and Blu-ray discs are generally sold with a right of return. We record a provision for sales returns and allowances at the time of sale based upon an estimate of future returns, rebates and other incentives. In determining this provision, we consider sources of qualitative and quantitative evidence including forecast sales data, customers’ rights of return, sales levels for units already shipped, historical return rates for similar products, current economic trends, the competitive environment, promotions and our sales strategies. Reserves for sales returns and allowances of $153 million and $186 million at December 31, 2019 and 2018 , respectively, are recorded in “Other current liabilities” on the Consolidated Balance Sheets. Reserves for accounts receivable are estimated based on historical bad debt experience, the aging of accounts receivable, industry trends and economic indicators, as well as recent payment history for specific customers. Our allowance for doubtful accounts was $86 million at both December 31, 2019 and 2018 . The provision for doubtful accounts charged to expense was $26 million in each of the years 2019 and 2018 , and $31 million in 2017 . Noncurrent Accounts Receivables —Included in “Other assets” on the Consolidated Balance Sheets are noncurrent accounts receivables of $2.11 billion and $1.84 billion at December 31, 2019 and 2018 , respectively. Noncurrent accounts receivables primarily relate to revenues recognized under long-term television licensing arrangements. Television license fee revenues are recognized at the beginning of the license period in which programs are made available to the licensee for exhibition, while the related cash is generally collected over the term of the license period. Contract Liabilities —A contract liability is recorded when consideration is received from a customer prior to fully satisfying a performance obligation in a contract. Our contract liabilities primarily consist of cash received related to advertising arrangements for which the required audience rating or impressions have not been delivered; consumer products arrangements with minimum guarantees; and television licensing arrangements under which the content has not yet been made available to the customer. These contract liabilities will be recognized as revenues when control of the related product or service is transferred to the customer. Contract liabilities are included in “Deferred revenues” and “Other liabilities” on the Consolidated Balance Sheets and were $910 million and $745 million at December 31, 2019 and December 31, 2018 , respectively. The change in contract liabilities for the year ended December 31, 2019 primarily reflects cash payments received during the period for which the performance obligation was not satisfied prior to the end of the period partially offset by $501 million of revenues recognized that were included in deferred revenues at December 31, 2018 . For the year ended December 31, 2018 , we recognized revenues of $560 million that were included in deferred revenues at December 31, 2017 . Unrecognized Revenues Under Contract —As of December 31, 2019 , unrecognized revenues attributable to unsatisfied performance obligations under our long-term contracts was $7.72 billion , of which $4.27 billion is expected to be recognized in 2020 , $1.93 billion in 2021 , $1.04 billion in 2022 , and $478 million thereafter. These amounts only include contracts subject to a guaranteed fixed amount or the guaranteed minimum under variable contracts, primarily consisting of television and film licensing contracts and affiliate arrangements that are subject to a fixed or guaranteed minimum fee. Such amounts change on a regular basis as we renew existing agreements or enter into new agreements. Unrecognized revenues under contract disclosed above do not include (i) contracts with an original expected term of one year or less, mainly consisting of our advertising contracts (ii) contracts for which variable consideration is determined based on the customer’s subsequent sale or usage, mainly consisting of affiliate agreements and (iii) long-term licensing agreements for multiple programs for which our right to invoice corresponds with the value of the programs provided to the customer. Performance Obligations Satisfied in Previous Periods —Under certain licensing arrangements, the amount and timing of our revenue recognition is determined based on our licensees’ subsequent sale to its end customers. As a result, under such arrangements, which primarily include licensing of our content to distributors of transactional video-on-demand and electronic sell-through services, we often satisfy our performance obligation of delivery of our content in advance of revenue recognition. During the years ended December 31, 2019 and 2018 , we recognized revenues of approximately $235 million and $172 million , respectively in our Filmed Entertainment segment for such performance obligations satisfied, or partially satisfied, in a prior period. Collaborative Arrangements —Collaborative arrangements primarily consist of joint efforts with third parties to produce and distribute programming such as television series and live sporting events, including the agreement between us and Turner Broadcasting System, Inc. to telecast the NCAA Division I Men’s Basketball Championship (“NCAA Tournament”), which runs through 2032. In connection with this agreement for the NCAA Tournament, advertisements aired on the CBS Television Network are recorded as revenues and our share of the program rights fees and other operating costs are recorded as operating expenses. We also enter into collaborative arrangements with other studios to jointly finance and distribute film and television programming, under which each partner is responsible for distribution of the program in specific territories or distribution windows. Under these arra |
