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 Studios; CBS Media Ventures; CBS-branded streaming services, including CBS All Access, which will be rebranded as Paramount+ in March 2021, and CBSN; CBS Sports Network; and CBS Television Stations), Cable Networks (premium and basic cable networks, including Showtime, BET, Nickelodeon, MTV, Comedy Central, Paramount Network, and Smithsonian Channel, among others; streaming services, including Pluto TV and Showtime OTT; ViacomCBS Networks International, including Channel 5, Telefe and Network 10) and Filmed Entertainment (Paramount Pictures, Paramount Players, Paramount Animation, Paramount Television Studios and Miramax). 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. 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. Discontinued Operations —On November 25, 2020, we entered into an agreement to sell our publishing business, Simon & Schuster, to Penguin Random House LLC (“Penguin Random House”), a wholly owned subsidiary of Bertelsmann SE & Co. KGaA, for $2.175 billion in cash. As a result, Simon & Schuster has been presented as a discontinued operation in our consolidated financial statements for all periods presented (see Note 3). 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 of investee companies, net of tax” on the Consolidated Statements of Operations. Reclassifications —Certain amounts reported for prior years have been reclassified to conform to the current year’s presentation. 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. The coronavirus disease (“COVID-19”) pandemic has negatively impacted the macroeconomic environment in the United States and globally, as well as our business, financial condition and results of operations. Due to the evolving and uncertain nature of COVID-19, it is reasonably possible that it could materially impact our estimates, particularly those that require consideration of forecasted financial information. These estimates relate to certain accounts including, but not limited to, receivables, programming and other inventory, deferred income tax assets, finite and indefinite lived intangible assets, including goodwill and FCC licenses, and other long-lived assets. The magnitude of the impact will depend on numerous evolving factors that we may not be able to accurately predict or control, including the duration and extent of the pandemic, the impact of federal, state, local and foreign governmental actions, consumer behavior in response to the pandemic and such governmental actions, and the economic and operating conditions that we may face in the aftermath of COVID-19. 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, 2020 and 2019, we had restricted cash of $135 million and $202 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 produce and acquire rights to programming to exhibit on our broadcast and cable networks, on our broadcast television stations, direct to consumers through our streaming services, and in theaters. We also produce programming for third parties. Costs for internally-produced and acquired programming inventory, including prepayments for such costs, are recorded within the non-current portion of “Programming and other inventory” on the Consolidated Balance Sheet. Prepayments for the rights to air sporting and other live events that are expected to be expensed over the next 12 months are classified within the current portion of “Programming and other inventory” on the Consolidated Balance Sheet. 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 and amortized over the projected life of each television program or feature film. Costs incurred to acquire television series and feature film programming rights, including advances, are capitalized when the license period has begun and the program is accepted and available for airing and amortized over the shorter of the license period or the period in which an economic benefit is expected to be derived. For internally-produced television programs and feature films that are predominantly monetized on an individual basis, we use an individual-film-forecast computation method to amortize capitalized production costs and to accrue estimated liabilities for participations and residuals 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 of capitalized production costs and expensing of participations and residual costs. For television programming, our estimate of Ultimate Revenues includes revenues to be earned within 10 years from the delivery of the first episode, or, if still in production, 5 years from the delivery of the most recent episode, if later. These estimates are based on the past performance of similar television programs in a market, the performance in the initial markets and future firm commitments to license programs. 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 television and 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. 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. For programming that is predominantly monetized as part of a film group, which includes our acquired programming rights and certain internally-produced television programs, capitalized costs are amortized based on an estimate of the timing of our usage of and benefit from such programming. 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 and amortized 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. We test a film group or individual television program or feature film for impairment when events or circumstances indicate that its fair value may be less than its unamortized cost. If the carrying value of a film group or individual television program or feature film exceeds the estimated fair value, an impairment charge will then be recorded in the amount of the difference. In addition, unamortized costs for internally-produced or acquired programming that have been substantively abandoned are written off. 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 group may not be recoverable. Recoverability of these asset groups is determined by comparing the forecasted undiscounted cash flows expected to be generated by these asset groups 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 assets. Investments —Investments over which we have a significant influence, without a controlling interest, are accounted for under the equity method. Equity investments for which we have no significant influence are measured at fair value where a readily determinable fair value exists. Equity 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 “Net gains (losses) from investments” in the Consolidated Statements of Operations. 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, 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 6). 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. Other assets and liabilities, including television and film 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 when the hedged items are recognized. 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” 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 streaming services (“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 (“reverse compensation”); and subscription fees for our streaming subscription offerings, including CBS All Access (to be rebranded as Paramount+ in March 2021) , Showtime Networks’ premium subscription streaming service (“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 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 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. Revenue Allowances —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 $64 million and $58 million at December 31, 2020 and 2019, respectively, are recorded in “Other current liabilities” on the Consolidated Balance Sheets. Reserves for accounts receivable reflect our expected credit losses, which are estimated based on historical experience, as well as current and expected economic conditions and industry trends. Our allowance for doubtful accounts was $85 million and $80 million at December 31, 2020 and 2019, respectively. The provision for doubtful accounts charged to expense was $32 million in 2020, $25 million in 2019 and $24 million in 2018. 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 within “Deferred revenues” and “Other liabilities” on the Consolidated Balance Sheets. 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 (the “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 arrangements, co-production costs are initially capitalized as programming inventory and amortized over the estimated economic life of the program. In such arrangements where we have distribution rights, all proceeds generated from such distribution are recorded as revenues and any participation profits due to third party collaborators are recorded as participation expenses. In co-production arrangements where third party collaborators have distribution rights, our net participating profits are recorded as revenues. Amounts attributable to transactions arising from collaborative arrangements between participants were not material to the consolidated financial statements for any period presented. Leases —We have operating leases primarily for office space, equipment, satellite transponders and studio facilities and finance leases for satellite transponders and equipment. We determine that a contract contains a lease if we obtain substantially all of the economic benefits of, and the right to direct the use of, an asset identified in the contract. For leases with terms greater than 12 months, we record a right-of-use asset and a lease liability representing the present value of future lease payments. The discount rate used to measure the lease asset and liability is determined at the beginning of the lease term using the rate implicit in the lease, if readily determinable, or our collateralized incremental borrowing rate. For those contracts that include fixed rental payments for both the use of the asset (“lease costs”) as well as for other occupancy or service costs relating to the asset (“non-lease costs”), we generally include both the lease costs and non-lease costs in the measurement of the lease asset and liability. We also own buildings and production facilities where we lease space to lessees. Our leases generally have remaining terms ranging from one Advertising —Advertising costs are expensed as incurred. We incurred total advertising expenses of $1.31 billion in 2020, $1.67 billion in 2019 and $1.39 billion in 2018. Interest —Costs associated with the refinancing or issuance of debt, as well as debt discounts or premiums, are recorded as interest over the term of the related debt. We may enter into interest rate exchange agreements; the amount to be paid or received under such agreements is accrued and recognized over the life of the agreement as an adjustment to interest expense. Income Taxes —The provision for income taxes includes federal, state, local, and foreign taxes. Deferred tax assets and liabilities are recognized for the estimated future tax effects of temporary differences between the financial statement carrying amounts and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which the temporary differences are expected to be reversed. We evaluate the realizability of deferred tax assets and establish a valuation allowance when it is more likely than not that all or a portion of deferred tax assets will not be realized. Deferred tax assets and deferred tax liabilities are classified as noncurrent on the Consolidated Balance Sheets. For tax positions taken in a previously filed |
