Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business YUM! Brands, Inc. and its Subsidiaries (collectively referred to herein as “YUM” or the “Company”) comprise the worldwide operations of KFC, Pizza Hut and Taco Bell (collectively the “Concepts”). YUM has over 45,000 units of which 60% are located outside the U.S. in more than 135 countries and territories. YUM was created as an independent, publicly-owned company on October 6, 1997 via a tax-free distribution by our former parent, PepsiCo, Inc., of our Common Stock to its shareholders. References to YUM throughout these Consolidated Financial Statements are made using the first person notations of “we,” “us” or “our.” Through our widely-recognized Concepts, we develop, operate or franchise a system of both traditional and non-traditional quick service restaurants. The terms "franchise" or "franchisee" within these Consolidated Financial Statements are meant to describe third parties that operate units under either franchise or license agreements. Each Concept has proprietary menu items and emphasizes the preparation of food with high quality ingredients as well as unique recipes and special seasonings to provide appealing, convenient, tasty and attractive food at competitive prices. Our traditional restaurants feature dine-in, carryout and, in some instances, drive-thru or delivery service. Non-traditional units include express units and kiosks which have a more limited menu and operate in non-traditional locations like malls, airports, gasoline service stations, train stations, subways, convenience stores, stadiums, amusement parks and colleges, where a full-scale traditional outlet would not be practical or efficient. We also operate multibrand units, where two or more of our Concepts are operated in a single unit. As of December 31, 2017 , YUM consisted of three operating segments: • The KFC Division which includes our worldwide operations of the KFC concept • The Pizza Hut Division which includes our worldwide operations of the Pizza Hut concept • The Taco Bell Division which includes our worldwide operations of the Taco Bell concept On October 31, 2016 (the “Distribution Date”), we completed the spin-off of our China business (the "Separation") into an independent, publicly-traded company under the name of Yum China Holdings, Inc. (“Yum China”). On the Distribution Date, we distributed to each of our shareholders of record as of the close of business on October 19, 2016 (the “Record Date”) one share of Yum China common stock for each share of our Common Stock held as of the Record Date. The distribution was structured to be a tax free distribution to our U.S. shareholders for federal income tax purposes in the U.S. Yum China’s common stock trades on the New York Stock Exchange under the symbol “YUMC.” After the distribution, we do not beneficially own any shares of Yum China common stock.

Summary of Significant Accounti

Summary of Significant Accounting Policies	Dec. 31, 2017
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Our preparation of the accompanying Consolidated Financial Statements in conformity with Generally Accepted Accounting Principles in the United States of America (“GAAP”) requires us to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Principles of Consolidation and Basis of Preparation. Intercompany accounts and transactions have been eliminated in consolidation. We consolidate entities in which we have a controlling financial interest, the usual condition of which is ownership of a majority voting interest. We also consider for consolidation an entity, in which we have certain interests, where the controlling financial interest may be achieved through arrangements that do not involve voting interests. Such an entity, known as a variable interest entity (“VIE”), is required to be consolidated by its primary beneficiary. The primary beneficiary is the entity that possesses the power to direct the activities of the VIE that most significantly impact its economic performance and has the obligation to absorb losses or the right to receive benefits from the VIE that are significant to it. Our most significant variable interests are in entities that operate restaurants under our Concepts’ franchise and license arrangements. We do not have an equity interest in any of our franchisee businesses. Additionally, we do not typically provide significant financial support such as loans or guarantees to our franchisees. However, we do have variable interests in certain franchisees through real estate lease arrangements to which we are a party. At the end of 2017 , YUM has future lease payments due from franchisees, on a nominal basis, of approximately $725 million , and we are contingently liable on certain other lease agreements that have been assigned to franchisees. See the Lease Guarantees and Franchise Loan Pool and Equipment Guarantees sections in Note 20. As our franchise and license arrangements provide our franchisee entities the power to direct the activities that most significantly impact their economic performance, we do not consider ourselves the primary beneficiary of any such entity that might otherwise be considered a VIE. See Note 20 for additional information on our entity that operates a franchise lending program that is a VIE in which we have a variable interest but for which we are not the primary beneficiary and thus do not consolidate. We participate in various advertising cooperatives with our franchisees established to collect and administer funds contributed for use in advertising and promotional programs designed to increase sales and enhance the reputation of the Company and its franchise owners. Contributions to the advertising cooperatives are required for both Company-owned and franchise restaurants and are generally based on a percentage of restaurant sales. We maintain certain variable interests in these cooperatives. As the cooperatives are required to spend all funds collected on advertising and promotional programs, total equity at risk is not sufficient to permit the cooperatives to finance their activities without additional subordinated financial support. Therefore, these cooperatives are VIEs. As a result of our voting rights, we consolidate certain of these cooperatives for which we are the primary beneficiary. Advertising cooperative assets, consisting primarily of cash received from the Company and franchisees and accounts receivable from franchisees, can only be used to settle obligations of the respective cooperative. Advertising cooperative liabilities represent the corresponding obligation arising from the receipt of the contributions to purchase advertising and promotional programs for which creditors do not have recourse to the general credit of the Company as the primary beneficiary. Therefore, we report all assets and liabilities of these advertising cooperatives that we consolidate as Advertising cooperative assets, restricted and Advertising cooperative liabilities in the Consolidated Balance Sheet. As the contributions to these cooperatives are designated and segregated for advertising, we act as an agent for the franchisees with regard to these contributions. Thus, we do not reflect franchisee contributions to these cooperatives in our Consolidated Statements of Income or Consolidated Statements of Cash Flows. Fiscal Year. Our fiscal years have historically ended on the last Saturday in December and, as a result, a 53 rd week was added every five or six years. The first three quarters of each fiscal year consisted of 12 weeks and the fourth quarter consisted of 16 weeks in fiscal years with 52 weeks and 17 weeks in fiscal years with 53 weeks. Our U.S. subsidiaries and certain international subsidiaries operated on similar fiscal calendars. Our remaining international subsidiaries operated on a monthly calendar, and thus never had a 53 rd week, with two months in the first quarter, three months in the second and third quarters and four months in the fourth quarter. Certain international subsidiaries within our KFC, Pizza Hut and Taco Bell divisions have historically closed approximately one month or one period earlier to facilitate consolidated reporting. Fiscal year 2016 included 53 weeks for our U.S. businesses and for our international subsidiaries that reported on a period calendar. The 53 rd week added $76 million to Total revenues and $28 million to Operating Profit in our 2016 Consolidated Statement of Income. On January 27, 2017, YUM’s Board of Directors approved a change in the Company's fiscal year from a year ending on the last Saturday of December to a year beginning on January 1 and ending December 31 of each year, commencing with the year ending December 31, 2017. In connection with this change, the Company moved from a 52-week periodic fiscal calendar with three 12-week interim quarters and a 16-week fourth quarter to a monthly reporting calendar with each quarter comprised of three months. Our U.S. subsidiaries continue to report on a period calendar as described above. Concurrent with the change in the Company's fiscal year, we also eliminated the one month or one period reporting lags of our international subsidiaries. As a result of removing these reporting lags, each international subsidiary operates either on a monthly calendar consistent with the Company’s new calendar or on a periodic calendar consistent with our U.S. subsidiaries. We believe this change in our international subsidiary reporting calendars and the resulting elimination of reporting lags is preferable because a more current reporting calendar allows the Consolidated Financial Statements to more consistently and more timely reflect the impact of current events, economic conditions and global trends. The change to the Company’s fiscal year and removal of the international reporting lags is effective in 2017. We have applied this change in accounting principle retrospectively to all prior financial periods presented and the impact of this change is summarized in Note 5. The impact of the change in accounting principle on the current period Consolidated Financial Statements is similar to the impact on the prior period results discussed in Note 5. Foreign Currency. The functional currency of our foreign entities is the currency of the primary economic environment in which the entity operates. Functional currency determinations are made based upon a number of economic factors, including but not limited to cash flows and financing transactions. The operations, assets and liabilities of our entities outside the U.S. are initially measured using the functional currency of that entity. Income and expense accounts for our operations of these foreign entities are then translated into U.S. dollars at the average exchange rates prevailing during the period. Assets and liabilities of these foreign entities are then translated into U.S. dollars at exchange rates in effect at the balance sheet date. As of December 31, 2017 , net cumulative translation adjustment losses of $174 million are recorded in Accumulated other comprehensive loss ("AOCI") in the Consolidated Balance Sheet. The majority of our foreign currency net asset exposure is in countries where we have Company-owned restaurants. As we manage and share resources at the individual brand level within a country, cumulative translation adjustments are recorded and tracked at the foreign-entity level that represents the operations of our individual brands within that country. Translation adjustments recorded in AOCI are subsequently recognized as income or expense generally only upon sale of the related investment in a foreign entity, or upon a sale of assets and liabilities within a foreign entity that represents a complete or substantially complete liquidation of that foreign entity. For purposes of determining whether a sale or complete or substantially complete liquidation of an investment in a foreign entity has occurred, we consider those same foreign entities for which we record and track cumulative translation adjustments. Gains and losses arising from the impact of foreign currency exchange rate fluctuations on transactions in foreign currency are included in Other (income) expense in our Consolidated Statements of Income. Reclassifications. We have reclassified certain items in the Consolidated Financial Statements for prior periods to be comparable with the classification for the fiscal year ended December 31, 2017 . These reclassifications had no effect on previously reported Net Income, as restated. Franchise Operations. We execute store-level franchise agreements for units operated by third parties which set out the terms of our arrangement with the franchisee. Our franchise agreements typically require the franchisee to pay an initial, non-refundable fee upon an individual store opening and continuing fees based upon a percentage of sales. Subject to our approval and their payment of a renewal fee, a franchisee may generally renew the franchise agreement upon its expiration. Additionally, we execute master franchise agreements in certain regions that transfer administrative and development obligations and sub-franchising rights to a franchisee in exchange for reduced franchise fees. The internal costs we incur to provide support services to our franchisees are charged to General and administrative expenses (“G&A”) as incurred. Certain direct costs of our franchise operations are charged to Franchise and license expenses. These costs include provisions for estimated uncollectible fees, rent or depreciation expense associated with restaurants we lease or sublease to franchisees, franchise marketing funding, amortization expense for franchise-related intangible assets, value added taxes on royalties and certain other direct incremental franchise support costs. Revenue Recognition. Revenues from Company-owned restaurants are recognized when payment is tendered at the time of sale. The Company presents sales net of sales-related taxes. Income from our franchisees includes initial fees, continuing fees, renewal fees and rental income from restaurants we lease or sublease to them. We recognize initial fees received from a franchisee as revenue when we have performed substantially all initial services required by the franchise agreement, which is generally upon the opening of a store. We recognize continuing fees, which are based upon a percentage of franchisee sales as those sales occur and rental income is recognized as it is earned. We recognize renewal fees when a renewal agreement with a franchisee becomes effective. While the majority of our franchise agreements are entered into with terms and conditions consistent with those at a prevailing market rate, there are instances when we enter into franchise agreements with terms that are not at market rates (for example, below-market continuing fees) for a specified period of time. We recognize the estimated value of terms in franchise agreements entered into concurrently with a refranchising transaction that are not consistent with market terms as part of the upfront Refranchising (gain) loss and amortize that amount into Franchise and license fees and income over the period such terms are in effect. The value of terms that are not considered to be at market within franchise agreements is estimated based upon the difference between the present value of the cash expected to be received under the franchise agreement and the present value of the cash that would have been expected to be received under a franchise agreement with terms substantially consistent with market. Direct Marketing Costs. To the extent we participate in advertising cooperatives, we expense our contributions as incurred which are based on a percentage of sales. We charge direct marketing costs incurred outside of a cooperative to expense ratably in relation to revenues over the year in which incurred and, in the case of advertising production costs, in the year the advertisement is first shown. Deferred direct marketing costs, which are classified as prepaid expenses, consist of media and related advertising production costs which will generally be used for the first time in the next fiscal year and have historically not been significant. Our advertising expenses were $245 million , $260 million and $253 million in 2017 , 2016 and 2015 , respectively. We report the majority of our direct marketing costs in Occupancy and other operating expenses as they are incurred as a percentage of sales by Company-owned restaurants. Advertising incurred on behalf of franchised restaurants is recorded within Franchise and license expenses, including $25 million related to the Pizza Hut U.S. Transformation Agreement and $20 million related to the KFC U.S. Acceleration Agreement in 2017. See Note 5 for further discussion of these agreements. Research and Development Expenses. Research and development expenses, which we expense as incurred, are reported in G&A. Research and development expenses were $22 million , $24 million and $23 million in 2017 , 2016 and 2015 , respectively. Share-Based Employee Compensation. We recognize ongoing share-based payments to employees, including grants of employee stock options and stock appreciation rights (“SARs”), in the Consolidated Financial Statements as compensation cost over the service period based on their fair value on the date of grant. This compensation cost is recognized over the service period on a straight-line basis, net of an assumed forfeiture rate, for awards that actually vest. We present this compensation cost consistent with the other compensation costs for the employee recipient in either Payroll and employee benefits or G&A. See Note 16 for further discussion of our share-based compensation plans. Legal Costs. Settlement costs are accrued when they are deemed probable and reasonably estimable. Anticipated legal fees related to self-insured workers' compensation, employment practices liability, general liability, automobile liability, product liability and property losses (collectively, "property and casualty losses") are accrued when deemed probable and reasonably estimable. Legal fees not related to self-insured property and casualty losses are recognized as incurred. See Note 20 for further discussion of our legal proceedings. Impairment or Disposal of Property, Plant and Equipment. Property, plant and equipment (“PP&E”) is tested for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. The assets are not recoverable if their carrying value is less than the undiscounted cash flows we expect to generate from such assets. If the assets are not deemed to be recoverable, impairment is measured based on the excess of their carrying value over their fair value. For purposes of impairment testing for our restaurants, we have concluded that an individual restaurant is the lowest level of independent cash flows unless it is more likely than not that we will refranchise restaurants as a group. We review our long-lived assets of such individual restaurants (primarily PP&E and allocated intangible assets subject to amortization) semi-annually for impairment, or whenever events or changes in circumstances indicate that the carrying amount of a restaurant may not be recoverable. We use two consecutive years of operating losses as our primary indicator of potential impairment for our semi-annual impairment testing of these restaurant assets. We evaluate the recoverability of these restaurant assets by comparing the estimated undiscounted future cash flows, which are based on our entity-specific assumptions, to the carrying value of such assets. For restaurant assets that are not deemed to be recoverable, we write-down an impaired restaurant to its estimated fair value, which becomes its new cost basis. Fair value is an estimate of the price a franchisee would pay for the restaurant and its related assets and is determined by discounting the estimated future after-tax cash flows of the restaurant, which include a deduction for royalties we would receive under a franchise agreement with terms substantially at market. The after-tax cash flows incorporate reasonable assumptions we believe a franchisee would make such as sales growth and margin improvement. The discount rate used in the fair value calculation is our estimate of the required rate of return that a franchisee would expect to receive when purchasing a similar restaurant and the related long-lived assets. The discount rate incorporates rates of returns for historical refranchising market transactions and is commensurate with the risks and uncertainty inherent in the forecasted cash flows. In executing our refranchising initiatives, we most often offer groups of restaurants for sale. When we believe it is more likely than not a restaurant or groups of restaurants will be refranchised for a price less than their carrying value, but do not believe the restaurant(s) have met the criteria to be classified as held for sale, we review the restaurants for impairment. We evaluate the recoverability of these restaurant assets by comparing estimated sales proceeds plus holding period cash flows, if any, to the carrying value of the restaurant or group of restaurants. For restaurant assets that are not deemed to be recoverable, we recognize impairment for any excess of carrying value over the fair value of the restaurants, which is based on the expected net sales proceeds. To the extent ongoing agreements to be entered into with the franchisee simultaneous with the refranchising are expected to contain terms, such as royalty rates, not at prevailing market rates, we consider the off-market terms in our impairment evaluation. We recognize any such impairment charges in Refranchising (gain) loss. Refranchising (gain) loss includes the gains or losses from the sales of our restaurants to new and existing franchisees, including any impairment charges discussed above, and associated termination, relocation or retention costs associated with store-level employees of refranchised stores or employees of restaurant-support centers which we have closed due to refranchising. We recognize gains on restaurant refranchisings when the sale transaction closes and control of the restaurant operations have transferred to the franchisee. When we decide to close a restaurant, it is reviewed for impairment and depreciable lives are adjusted based on the expected disposal date. Other costs incurred when closing a restaurant such as costs of disposing of the assets as well as other facility-related expenses from previously closed stores are generally expensed as incurred. Additionally, at the date we cease using a property under an operating lease, we record a liability for the net present value of any remaining lease obligations, net of estimated sublease income, if any. Any costs recorded upon store closure as well as any subsequent adjustments to liabilities for remaining lease obligations as a result of lease termination or changes in estimates of sublease income are recorded in Closures and impairment (income) expenses. To the extent we sell assets, primarily land, associated with a closed store, any gain or loss upon that sale is also recorded in Closures and impairment (income) expenses. Considerable management judgment is necessary to estimate future cash flows, including cash flows from continuing use, terminal value, sublease income and refranchising proceeds. Accordingly, actual results could vary significantly from our estimates. Guarantees. We recognize, at inception of a guarantee, a liability for the fair value of certain obligations undertaken. The majority of our guarantees are issued as a result of assigning our interest in obligations under operating leases as a condition to the refranchising of certain Company restaurants. We recognize a liability for the fair value of such lease guarantees upon refranchising and upon subsequent renewals of such leases when we remain contingently liable. The related expense and any subsequent changes are included in Refranchising (gain) loss. Any expense and subsequent changes in the guarantees for other franchise support guarantees not associated with a refranchising transaction are included in Franchise and license expense. Income Taxes. We record deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases as well as operating loss, capital loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those differences or carryforwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in our Income tax provision in the period that includes the enactment date. Additionally, in determining the need for recording a valuation allowance against the carrying amount of deferred tax assets, we consider the amount of taxable income and periods over which it must be earned, actual levels of past taxable income and known trends and events or transactions that are expected to affect future levels of taxable income. Where we determine that it is more likely than not that all or a portion of an asset will not be realized, we record a valuation allowance. We recognize the benefit of positions taken or expected to be taken in our tax returns in our income tax provision when it is more likely than not (i.e. a likelihood of more than fifty percent) that the position would be sustained upon examination by tax authorities. A recognized tax position is then measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon settlement. We evaluate these amounts on a quarterly basis to ensure that they have been appropriately adjusted for audit settlements and other events we believe may impact the outcome. Changes in judgment that result in subsequent recognition, derecognition or a change in measurement of a tax position taken in a prior annual period (including any related interest and penalties) are recognized as a discrete item in the interim period in which the change occurs. We recognize accrued interest and penalties related to unrecognized tax benefits as components of our income tax provision. We do not record a deferred tax liability for unremitted earnings of our foreign subsidiaries (except for the U.S. tax provided for as part of the Tax Act enacted on December 22, 2017, see Note 18) to the extent that the earnings meet the indefinite reversal criteria. This criteria is met if the foreign subsidiary has invested, or will invest, the earnings indefinitely. The decision as to the amount of unremitted earnings that we intend to maintain in non-U.S. subsidiaries considers items including, but not limited to, forecasts and budgets of financial needs of cash for working capital, liquidity plans and expected cash requirements in the U.S. See Note 18 for a further discussion of our income taxes. Fair Value Measurements. Fair value is the price we would receive to sell an asset or pay to transfer a liability (exit price) in an orderly transaction between market participants. For those assets and liabilities we record or disclose at fair value, we determine fair value based upon the quoted market price, if available. If a quoted market price is not available for identical assets, we determine fair value based upon the quoted market price of similar assets or the present value of expected future cash flows considering the risks involved, including counterparty performance risk if appropriate, and using discount rates appropriate for the duration. The fair values are assigned a level within the fair value hierarchy, depending on the source of the inputs into the calculation. Level 1 Inputs based upon quoted prices in active markets for identical assets. Level 2 Inputs other than quoted prices included within Level 1 that are observable for the asset, either directly or indirectly. Level 3 Inputs that are unobservable for the asset. Cash and Cash Equivalents. Cash equivalents represent funds we have temporarily invested (with original maturities not exceeding three months), including short-term, highly liquid debt securities. Cash and overdraft balances that meet the criteria for right of setoff are presented net on our Consolidated Balance Sheet. Receivables. The Company’s receivables are primarily generated from ongoing business relationships with our franchisees as a result of franchise and lease agreements. Trade receivables consisting of royalties from franchisees, including Yum China, are generally due within 30 days of the period in which the corresponding sales occur and are classified as Accounts and notes receivable, net on our Consolidated Balance Sheet. Yum China is our largest franchisee and we recorded franchise fee revenues of approximately $260 million from Yum China in 2017. Our provision for uncollectible franchisee receivable balances is based upon pre-defined aging criteria or upon the occurrence of other events that indicate that we may not collect the balance due. Additionally, we monitor the financial condition of our franchisees and record provisions for estimated losses on receivables when we believe it probable that our franchisees will be unable to make their required payments. While we use the best information available in making our determination, the ultimate recovery of recorded receivables is also dependent upon future economic events and other conditions that may be beyond our control. We recorded $5 million , less than $1 million and $6 million in net provisions within Franchise and license expenses in 2017 , 2016 and 2015 , respectively, related to uncollectible franchise and license trade receivables.Trade receivables that are ultimately deemed to be uncollectible, and for which collection efforts have been exhausted, are written off against the allowance for doubtful accounts. 2017 2016 Accounts and notes receivable $ 419 $ 384 Allowance for doubtful accounts (19 ) (14 ) Accounts and notes receivable, net $ 400 $ 370 Our financing receivables primarily consist of notes receivables and direct financing leases with franchisees which we enter into from time-to-time. As these receivables primarily relate to our ongoing business agreements with franchisees, we consider such receivables to have similar risk characteristics and evaluate them as one collective portfolio segment and class for determining the allowance for doubtful accounts. We monitor the financial condition of our franchisees and record provisions for estimated losses on receivables when we believe it is probable that our franchisees will be unable to make their required payments. Balances of notes receivable and direct financing leases due within one year are included in Accounts and notes receivable, net while amounts due beyond one year are included in Other assets. Amounts included in Other assets totaled $38 million and $29 million (net of an allowance of $2 million ) at December 31, 2017 and December 31, 2016 , respectively. Financing receivables that are ultimately deemed to be uncollectible, and for which collection efforts have been exhausted, are written off against the allowance for doubtful accounts. Interest income recorded on financing receivables has historically been insignificant. Inventories. We value our inventories at the lower of cost (computed on the first-in, first-out method) or market. Property, Plant and Equipment. We state PP&E at cost less accumulated depreciation and amortization. We calculate depreciation and amortization on a straight-line basis over the estimated useful lives of the assets as follows: 5 to 25 years for buildings and leasehold improvements, 3 to 20 years for machinery and equipment and 3 to 7 years for capitalized software costs. We suspend depreciation and amortization on assets that are held for sale. Leases and Leasehold Improvements. The Company leases land, buildings or both for certain of its restaurants and restaurant support centers worldwide. The length of our lease terms, which vary by country and often include renewal options, are an important factor in determining the appropriate accounting for leases including the initial classification of the lease as capital or operating and the timing of recognition of rent expense over the duration of the lease. We include renewal option periods in determining the term of our leases when failure to renew the lease would impose a penalty on the Company in such an amount that a renewal appears to be reasonably assured at the inception of the lease. The primary penalty to which we are subject is the economic detriment associated with the existence of leasehold improvements which might be impaired if we choose not to continue the use of the leased property. Leasehold improvements are amortized over the shorter of their estimated useful lives or the lease term. We generally do not receive leasehold improvement incentives upon opening a store that is subject to a lease. We expense rent associated with leased land or buildings while a restaurant is being constructed whether rent is paid or we are subject to a rent holiday. Additionally, certain of the Company's operating leases contain predetermined fixed escalations of the minimum rent during the lease term. For leases with fixed escalating payments and/or rent holidays, we record rent expense on a straight-line basis over the lease term, including any option periods considered in the determination of that lease term. Contingent rentals are based on sales levels in excess of stipulated amounts, and thus are not considered minimum lease payments and are included in rent expense when attainment of the contingency is considered probable (e.g. when Company sales occur). Internal Development Costs and Abandoned Site Costs. We capitalize direct costs associated with the site acquisition and construction of a Company unit on that site, including direct internal payroll and payroll-related costs. Only those site-specific costs incurred subsequent to the time that the site acquisition is considered probable are capitalized. If we subsequently make a determination that it is probable a site for which internal development costs have been capitalized will not be acquired or developed, any previously capitalized internal development costs are expensed and included in G&A. Goodwill and Intangible Assets. From time-to-time, the Company acquires restaurants from one of our Concept’s franchisees or acquires another business. Goodwill from these acquisitions represents the excess of the cost of a business acquired over the net of the amounts assigned to assets acquired, including identifiable intangible assets and liabilities assumed. Goodwill is not amortized and has been assigned to reporting units for purposes of impairment testing. Our reporting units are our business units (which are aligned based on geography) in our KFC, Pizza Hut and Taco Bell Divisions. We evaluate goodwill for impairment on an annual basis or more often if an event occurs or circumstances change that ind

Discontinued Operations and Disposal Groups [Abstract]
Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Discontinued Operations As discussed in Note 1, on October 31, 2016, the Company completed the Separation of our China business. In connection with the Separation, the Company and Yum China entered into a Separation and Distribution Agreement as well as various other agreements that provide a framework for the relationships between the parties, including among others a Tax Matters Agreement, an Employee Matters Agreement, a Transition Services Agreement and a Master License Agreement. These agreements provided for the allocation between the Company and Yum China of assets, employees, liabilities and obligations (including investments, property, employee benefits and tax-related assets and liabilities) attributable to periods prior to, at and after the Separation and govern certain relationships between the Company and Yum China after the Separation. For all the periods prior to the Separation, the financial results of Yum China are presented as Income from discontinued operations, net of tax in the Consolidated Statements of Income and Cash flows from discontinued operations in our Consolidated Statements of Cash Flows. The financial results of Yum China presented in discontinued operations reflect the results of the former China Division, an operating segment of the Company until the Separation, adjusted for the inclusion of certain G&A, non-cash impairment charges, refranchising gains, interest and income taxes that were previously not allocated to but were related to the former China Division's historical results of operations. Additionally, these financial results reflect a deduction for royalties on sales of KFC and Pizza Hut Company-owned stores in China that prior to the Separation were paid, pursuant to an intercompany franchise agreement, by an entity of Yum China to a Company entity. This royalty expense was not reflected in our China Division results that were presented prior to the Separation, as it was then an intercompany transaction that was eliminated in consolidation, but has been reflected in our Company's discontinued operations as such royalty arrangement continued pursuant to the Master License Agreement. Additionally, our China Division results that were presented prior to the Separation have been adjusted to exclude the portion of the royalties paid by third-party franchisees in China that have historically and continue to be remitted to a Company entity. These adjustments to our previously presented China Division results in determining Income from discontinued operations, net of tax were offset by adjustments to our KFC and Pizza Hut Divisions' results such that there was no impact on total reported Net Income. The following table presents the financial results of the Company’s discontinued operations: 2016 (a) 2015 Company sales $ 5,667 $ 6,789 Franchise and license fees and income 109 120 Company restaurant expenses (4,766 ) (5,913 ) G&A expenses (b) (406 ) (405 ) Franchise and license expenses (45 ) (48 ) Closures and impairment expenses (57 ) (64 ) Refranchising gain 12 13 Other income (c) 49 27 Interest income, net 8 7 Income from discontinued operations before income taxes 571 526 Income tax benefit (provision) (d) 65 (164 ) Income from discontinued operations - including noncontrolling interests 636 362 (Income) loss from discontinued operations - noncontrolling interests (11 ) (5 ) Income from discontinued operations, net of tax $ 625 $ 357 (a) Includes Yum China financial results from January 1, 2016 to October 31, 2016. (b) Includes costs incurred to execute the Separation of $68 million and $9 million for 2016 and 2015, respectively. Such costs primarily relate to transaction advisors, legal and other consulting fees. (c) Primarily relates to equity income from KFC franchisees in which Yum China owns a minority interest. (d) During 2016, we recorded a tax benefit of $233 million related to previously recorded losses associated with our Little Sheep business. The tax benefit associated with these losses was able to be recognized as a result of legal entity restructuring completed in anticipation of the Separation. Cash inflows from Yum China to the Company in 2017 and 2016, subsequent to the Separation, related to the Master License Agreement was $217 million and $16 million

Items Affecting Comparability Of Net Income And Cash Flows Disclosure [Abstract]
Items Affecting Comparability of Net Income and Cash Flows	Items Affecting Comparability of Net Income and Cash Flows Tax Cuts and Jobs Act of 2017 (“Tax Act”) We recognized $434 million in our 2017 Income tax provision as a result of the December 22, 2017 enactment of the Tax Act. See Note 18 for a discussion of the charge. Refranchising (Gain) Loss The Refranchising (gain) loss by reportable segment is presented below. Given the size and volatility of refranchising initiatives, our chief operating decision maker ("CODM") does not consider the impact of Refranchising (gain) loss when assessing segment performance. As such, we do not allocate such gains and losses to our segments for performance reporting purposes. During the years ended December 31, 2017, 2016 and 2015, we refranchised 1,470 , 432 and 270 restaurants, respectively. We received $1,773 million , $370 million and $213 million in pre-tax proceeds in 2017, 2016 and 2015, respectively, related to these transactions. A summary of Refranchising (gain) loss is as follows: Refranchising (gain) loss 2017 2016 2015 KFC Division (a) $ (581 ) $ (44 ) $ 32 Pizza Hut Division (a) (16 ) (48 ) 56 Taco Bell Division (486 ) (71 ) (65 ) Worldwide $ (1,083 ) $ (163 ) $ 23 (a) In 2010, we refranchised our then-remaining Company-operated restaurants in Mexico. To the extent we owned it, we did not sell the real estate related to certain of these restaurants, instead leasing it to the franchisee. During 2015, we sold the real estate for approximately $58 million . While these proceeds exceeded the book value of the real estate, the sale represented a substantial liquidation of our Mexican foreign entities under GAAP. As such, the accumulated translation losses associated with our Mexican business were included in our loss on the sale. We recorded charges of $80 million representing the excess of the sum of the book value of the real estate and other related assets and our accumulated translation losses over the sales price. Consistent with the classification of the original Mexico market-wide refranchising transaction, these charges were classified as Refranchising (gain) loss. Refranchising losses of $40 million were associated with both the KFC and Pizza Hut Divisions. We continue to earn U.S. dollar-denominated franchise fees, most of which are sales-based royalties, under our existing franchise contracts with our Mexico franchisee. As a result of classifying restaurant and related assets as held-for-sale and ceasing depreciation expense as well as recording any related write-downs to fair value, depreciation expense was reduced versus what would have otherwise been recorded by $10 million during the year ended December 31, 2017. Our CODM does not consider the impact of these depreciation reductions, which were recorded within Occupancy and other operating expenses when assessing segment performance. These depreciation reductions were not allocated to the Division segments resulting in depreciation expense continuing to be recorded within our Divisional results at the rate at which it was prior to the held-for-sale classification. YUM's Strategic Transformation Initiatives In October 2016, we announced our strategic transformation plans to drive global expansion of the KFC, Pizza Hut and Taco Bell brands ("YUM's Strategic Transformation Initiatives") following the then anticipated separation of our China business on October 31, 2016. Major features of the Company’s strategic transformation plans involve being more focused on the development of our three brands, increasing our franchise ownership and creating a leaner, more efficient cost structure. We incurred pre-tax costs of $23 million and $67 million related to our Strategic Transformation Initiatives in 2017 and 2016, respectively. In 2017, these costs were primarily recorded in G&A and included contract termination costs and relocation and severance costs for restaurant-support center employees. In 2016, these costs were primarily recorded in G&A and included restaurant-support center employee severance costs, charges associated with a voluntary retirement program offered to certain U.S. restaurant-support center employees, consulting costs incurred to facilitate YUM's Strategic Transformation Initiatives, and losses associated with our sale of Corporate aircraft upon our decision to no longer own aircraft. YUM's Strategic Transformation Initiatives represent the continuation of YUM's transformation of its operating model and capital structure following the Separation and recapitalization of YUM. Due to the scope of the initiatives as well as their significance, our CODM does not consider the associated cost when assessing segment performance. As such, these costs are not being allocated to any of our segment operating results for performance reporting purposes. Modifications of Share-based Compensation Awards In connection with the Separation, we modified certain share-based compensation awards held as part of our Executive Income Deferral ("EID") Plan in phantom shares of YUM Common Stock to provide one phantom Yum China share-based award for each outstanding phantom YUM share-based award. These Yum China awards may now be settled in cash, as opposed to stock, which requires recognition of the fair value of these awards within G&A in our Consolidated Income Statement. During 2017 and 2016, we recorded G&A charges related to these awards of $18 million and $30 million , respectively. Given these charges were a direct result of the Separation, our CODM does not consider their impact when assessing segment performance. As such, these costs are not being allocated to any of our segment operating results for performance reporting purposes. Pizza Hut U.S. Transformation Agreement In May 2017, we reached an agreement with Pizza Hut U.S. franchisees that will improve brand marketing alignment, accelerate enhancements in operations and technology and includes a permanent commitment to incremental advertising and digital and technology contributions by franchisees. In connection with this agreement, we anticipate investing approximately $90 million to upgrade restaurant equipment to improve operations, fund improvements in restaurant technology and enhance digital and e-commerce capabilities. We currently expect the majority of this investment will be split between 2017 and 2018. During 2017, we recorded pre-tax charges of $31 million , primarily within Franchise and license expenses or G&A, and capitalized $8 million of costs primarily related to digital and e-commerce initiatives. Due to their unique and long-term brand-building nature, our CODM does not consider the impact of these investments when assessing segment performance. As such, these investments are not being allocated to the Pizza Hut Division segment operating results for performance reporting purposes. In addition to the investments above, we have agreed to fund $37.5 million of incremental system advertising dollars from the second half of 2017 through 2018. During 2017, we incurred $25 million in related incremental system advertising expense. These advertising amounts were recorded primarily in Franchise and license expenses and are included in Pizza Hut's segment operating results. KFC U.S. Acceleration Agreement During 2015, we reached an agreement with our KFC U.S. franchisees that gave us brand marketing control as well as an accelerated path to expanded menu offerings, improved assets and enhanced customer experience. In connection with this agreement we anticipate investing a total of approximately $130 million from 2015 through 2018 primarily to fund new back-of house equipment for franchisees and to provide incentives to accelerate franchisee store remodels. We recorded pre-tax charges for the portion of these investments made in 2017, 2016 and 2015 of $17 million , $26 million and $72 million , respectively. These amounts were recorded primarily as Franchise and license expenses. These payments constitute a significant portion of the approximately $140 million asset for incentive payments made to franchisees which we will establish upon adoption of the new revenue recognition standard in 2018 (see Note 2). Due to their size and unique long-term brand building nature, our CODM does not consider the impact of these investments when assessing segment performance. As such, these charges are not being allocated to the KFC Division segment operating results for performance reporting purposes. In addition to the investments above, we agreed to fund $60 million of incremental system advertising. During 2017, 2016 and 2015, we incurred $20 million , $20 million and $10 million in incremental system advertising expense, respectively, with the remaining funding of approximately $10 million to occur in 2018. The incremental system advertising amounts recorded were primarily in Franchise and license expenses and are included in the KFC Division segment operating results. Items Impacting Other Pension (Income) Expense During the fourth quarter of 2016, the Company allowed certain former employees with deferred vested balances in the YUM Retirement Plan ("the Plan") an opportunity to voluntarily elect an early payout of their pension benefits. As a result of settlement payments made of approximately $205 million related to this program, all of which were funded from existing Plan assets, we recorded a settlement charge of $24 million to Other pension (income) expense. Due to the size and non-recurring nature of the program, our CODM does not consider the impact of these charges when assessing performance so they were not allocated to any of our segment operating results for performance reporting purposes. During the first quarter of 2017, as a result of the completion of a pension data review and reconciliation, we recorded a non-cash, out-of-year charge of $22 million to Other pension (income) expense to adjust our historical U.S. pension liability related to our deferred vested participants. Our CODM does not consider the impact of this charge when assessing segment performance given the number of years over which it accumulated. As such, this cost is not being allocated to any of our segment operating results for performance reporting purposes. See Note 15 for further discussion of our pension plans.

Remaining lease obligations for closed stores were not material at December 31, 2017 or December 31, 2016. Impact of Change in Reporting Calendar As discussed in Note 2, we have changed our fiscal year from a year ending on the last Saturday of December to a year beginning on January 1 and ending on December 31 of each year commencing with the year ending December 31, 2017. We also removed the monthly or period reporting lags certain of our international subsidiaries historically used to report results. The impacts on our Consolidated Financial Statements of retrospectively applying these changes are included below: 2016 As Previously Reported Adjustments After Change in Reporting Calendar Total revenues $ 6,366 $ (10 ) $ 6,356 Operating Profit 1,625 25 (a) 1,650 (b) Income from continuing operations 994 24 1,018 Income from discontinued operations, net of tax 625 — 625 Net Income $ 1,619 $ 24 1,643 Diluted EPS from continuing operations $ 2.48 $ 0.06 $ 2.54 Diluted EPS from discontinued operations 1.56 — 1.56 Diluted EPS $ 4.04 $ 0.06 $ 4.10 2015 As Previously Reported Adjustments After Change in Reporting Calendar Total revenues $ 6,440 $ (22 ) $ 6,418 Operating Profit 1,402 (8 ) 1,394 (b) Income from continuing operations 936 (10 ) 926 Income from discontinued operations, net of tax 357 — 357 Net Income $ 1,293 $ (10 ) $ 1,283 Diluted EPS from continuing operations $ 2.11 $ (0.02 ) $ 2.09 Diluted EPS from discontinued operations 0.81 — 0.81 Diluted EPS $ 2.92 $ (0.02 ) $ 2.90 (a) Primarily represents gains of $24 million related to the refranchising of certain international restaurants which occurred in December 2016. (b) Amount does not reconcile to our Consolidated Statements of Income for the year ended December 31, 2016 and December 31, 2015 due to the impact of retrospectively adopting a new accounting standard on Benefit Costs of $32 million and $40 million , respectively. See Note 2. In 2016, the impact on our Consolidated Statement of Cash Flows was a decrease in cash provided by operating activities of $39 million , a decrease in cash used in investing activities of $20 million and a decrease in cash used in financing activities of $16 million . In 2015, the impact on our Consolidated Statement of Cash Flows was an increase in cash used in investing activities of $10 million and a decrease in cash used in financing activities of $16 million . There was no impact to cash provided by operating activities. Our Shareholders' Equity, as of December 31, 2014, increased $9 million

("TBC") completed a securitization transaction and issued $800 million of its Series 2016-1 3.832% Fixed Rate Senior Secured Notes, Class A-2-I (the “Class A-2-I Notes”), $500 million of its Series 2016-1 4.377% Fixed Rate Senior Secured Notes, Class A-2-II (the “Class A-2-II Notes”) and $1.0 billion of its Series 2016-1 4.970% Fixed Rate Senior Secured Notes, Class A-2-III (the “Class A-2-III Notes” and, together with the Class A-2-I Notes and the Class A-2-II Notes, the “Class A-2 Notes”). In connection with the issuance of the Class A-2 Notes, the Issuer also entered into a revolving financing facility of Series 2016-1 Senior Notes, Class A-1 (the “Variable Funding Notes”), which allowed for the borrowing of up to $100 million and the issuance of up to $50 million in letters of credit. The Class A-2 Notes and the Variable Funding Notes are referred to collectively as the “Securitization Notes”. The Class A-2 Notes were issued under a Base Indenture, dated as of May 11, 2016 (the “Base Indenture”), and the related Series 2016-1 Supplement thereto, dated as of May 11, 2016 (the “Series 2016-1 Supplement”). The Base Indenture and the Series 2016-1 Supplement (collectively, the “Indenture”) allow the Issuer to issue additional series of notes. On October 16, 2017, the Issuer terminated the Variable Funding Notes. The Securitization Notes were issued in a transaction pursuant to which certain of TBC’s domestic assets, consisting principally of franchise-related agreements and domestic intellectual property, were contributed to the Issuer and the Issuer’s special purpose, wholly-owned subsidiaries (the “Guarantors”, and collectively with the Issuer, the "Securitization Entities") to secure the Securitization Notes. The Securitization Notes are secured by substantially all of the assets of the Securitization Entities, and include a lien on all existing and future U.S. Taco Bell franchise and license agreements and the royalties payable thereunder, existing and future U.S. Taco Bell intellectual property, certain transaction accounts and a pledge of the equity interests in asset-owning Securitization Entities. The remaining U.S. Taco Bell assets that were excluded from the transfers to the Securitization Entities continue to be held by Taco Bell of America, LLC, a limited liability company ("TBA") and TBC. The Securitization Notes are not guaranteed by the remaining U.S. Taco Bell assets, the Company, or any other subsidiary of the Company. Payments of interest and principal on the Securitization Notes are made from the royalty fees paid pursuant to the franchise and license agreements with all U.S. Taco Bell restaurants, including both company and franchise operated restaurants. Interest on and principal payments of the Class A-2 Notes are due on a quarterly basis. In general, no amortization of principal of the Class A-2 Notes is required prior to their anticipated repayment dates unless as of any quarterly measurement date the consolidated leverage ratio (the ratio of total debt to Net Cash Flow (as defined in the Indenture)) for the preceding four fiscal quarters of either the Company and its subsidiaries or the Issuer and its subsidiaries exceeds 5.0:1, in which case amortization payments of 1% per year of the outstanding principal as of the closing of the Securitization Notes is required. As of the most recent quarterly measurement date the consolidated leverage ratio exceeded 5.0:1 and, as a result, amortization payments are required. The legal final maturity date of the Notes is in May 2046, but the anticipated repayment dates of the Class A-2-I Notes, the Class A-2-II Notes and the Class A-2-III Notes will be 4 , 7 and 10 years, respectively (the “Anticipated Repayment Dates”) from the date of issuance. If the Issuer has not repaid or refinanced a series of Class A-2 Notes prior to its respective Anticipated Repayment Dates, rapid amortization of principal on all Securitization Notes will occur and additional interest will accrue on the Class A-2 Notes, as stated in the Indenture. The Company paid debt issuance costs of $31 million in connection with the 2016 issuance of the Securitization Notes. The debt issuance costs are being amortized to Interest expense, net through the Anticipated Repayment Dates of the Securitization Notes utilizing the effective interest rate method. As of December 31, 2017, the effective interest rates, including the amortization of debt issuance costs, were 4.18% , 4.59% , and 5.14% for the Class A-2-I Notes, Class A-2-II Notes and Class A-2-III Notes, respectively. During 2017, $2 million of unamortized debt issuance costs were recognized within Interest expense, net due to the termination of the Variable Funding Notes. The Securitization Notes are subject to a series of covenants and restrictions customary for transactions of this type, including (i) that the Issuer maintains specified reserve accounts to be available to make required interest payments in respect of the Securitization Notes, (ii) provisions relating to optional and mandatory prepayments and the related payment of specified amounts, including specified make-whole payments in the case of the Class A-2 Notes under certain circumstances, (iii) certain indemnification payments relating to taxes, enforcement costs and other customary items and (iv) covenants relating to recordkeeping, access to information and similar matters. The Securitization Notes are also subject to rapid amortization events provided for in the Indenture, including events tied to failure to maintain a stated debt service coverage ratio (as defined in the Indenture) of at least 1.1:1 , gross domestic sales for branded restaurants being below certain levels on certain measurement dates, a manager termination event, an event of default and the failure to repay or refinance the Class A-2 Notes on the Anticipated Repayment Date (subject to limited cure rights). The Securitization Notes are also subject to certain customary events of default, including events relating to non-payment of required interest or principal due on the Securitization Notes, failure to comply with covenants within certain time frames, certain bankruptcy events, breaches of specified representations and warranties, failure of security interests to be effective, certain judgments and failure of the Securitization Entities to maintain a stated debt service coverage ratio . As of December 31, 2017, we were in compliance with all of our debt covenant requirements and were not subject to any rapid amortization events . In accordance with the Indenture, certain cash accounts have been established with the Indenture trustee for the benefit of the note holders, and are restricted in their use. The Indenture requires a certain amount of securitization cash flow collections to be allocated on a weekly basis and maintained in a cash reserve account. As of December 31, 2017, the Company had restricted cash of $60 million primarily related to required interest reserves included in Prepaid expenses and other current assets on the Consolidated Balance Sheets. Once the required obligations are satisfied, there are no further restrictions, including payment of dividends, on the cash flows of the Securitization Entities. Additional cash reserves are required if any of the rapid amortization events occur, as noted above, or in the event that as of any quarterly measurement date the Securitization Entities fail to maintain a debt service coverage ratio (or the ratio of Net Cash Flow to all debt service payments for the preceding four fiscal quarters) of at least 1.75:1 . The amount of weekly securitization cash flow collections that exceed the required weekly allocations is generally remitted to the Company. During the quarter ended December 31, 2017, the Securitization Entities maintained a debt service coverage ratio significantly in excess of the 1.75:1 requirement . Credit Facilities and Subsidiary Senior Unsecured Notes On June 16, 2016, KFC Holding Co., Pizza Hut Holdings, LLC, a limited liability company, and TBA, each of which is a wholly-owned subsidiary of the Company, as co-borrowers (the "Borrowers"), entered into a credit agreement providing for senior secured credit facilities consisting of a $500 million Term Loan A facility (the “Term Loan A Facility"), a $2.0 billion Term Loan B facility (the “Term Loan B Facility”) and a $1.0 billion revolving facility (the “Revolving Facility”), each of which may be increased subject to certain conditions. The Term Loan A Facility, the Term Loan B Facility, and the Revolving Facility are collectively referred to as the "Credit Agreement". There are no outstanding borrowings under the Revolving Facility and $4 million of letters of credit outstanding as of December 31, 2017. The Term Loan A Facility was originally subject to quarterly amortization payments beginning one full fiscal quarter after the first anniversary of the closing date , in an amount equal to 1.25% of the initial principal amount of the facility, in each of the second and third years of the facility; in an amount equal to 1.875% of the initial principal amount of the facility, in the fourth year of the facility; and in an amount equal to 3.75% of the initial principal amount of the facility, in the fifth year of the facility, with the balance payable at maturity on the fifth anniversary of the closing date. (Subsequently, this amortization schedule was delayed by approximately one year and the maturity date was extended to June 7, 2022 as a result of the Term Loan A repricing in 2017. See below.) The Term Loan B Facility is subject to quarterly amortization payments in an amount equal to 0.25% of the initial principal amount of the facility, with the balance payable at maturity on the seventh anniversary of the closing date. On March 21, 2017, the Borrowers completed the repricing of the then existing $1.99 billion under the Term Loan B Facility pursuant to an amendment to the Credit Agreement. The amendment reduces the interest rate applicable to the Term Loan B Facility by 75 basis points to LIBOR plus 2.00% or Base Rate plus 1.00% , at the Borrower’s election, with an additional rate stepdown to LIBOR plus 1.75% or Base Rate plus 0.75% in the event the secured net leverage ratio (as defined in the Credit Agreement) is less than 1 to 1. As a result of repricing the Term Loan B Facility, $192 million in principal was assigned to new lenders or existing lenders electing to increase their holdings in the loan. The maturity date and all other material provisions under the Credit Agreement remained unchanged as a result of this amendment. On June 7, 2017, the Borrowers completed the repricing of the existing $500 million under the Term Loan A Facility and $1 billion under the Revolving Facility pursuant to an amendment to the Credit Agreement. The amendment reduced the interest rate applicable to the Term Loan A Facility and for borrowings under the Revolving Facility by 75 basis points. Subsequent to the repricing the interest rate ranges from 1.25% to 1.75% plus LIBOR or from 0.25% to 0.75% plus the Base Rate, at the Borrower’s election, based upon the total net leverage ratio of the Borrowers and the Specified Guarantors (as defined in the Credit Agreement). As a result of repricing the Term Loan A Facility, $146 million in principal was assigned to new lenders or existing lenders electing to increase their holdings in the loan. There was no change in lender participation in the Revolving Facility. The maturity date for the Term Loan A Facility and the Revolving Facility has been extended to June 7, 2022. Amortization payments on the Term Loan A Facility will begin one full fiscal quarter after the first anniversary of the amendment effective date, which delays the original amortization schedule by approximately one year. All other material provisions under the Credit Agreement remained unchanged. The Credit Agreement is unconditionally guaranteed by the Company and certain of the Borrowers’ principal domestic subsidiaries and excludes Taco Bell Funding LLC and its special purpose, wholly-owned subsidiaries (see above). The Credit Agreement is also secured by first priority liens on substantially all assets of the Borrowers and each subsidiary guarantor, excluding the stock of certain subsidiaries and certain real property, and subject to other customary exceptions. The Credit Agreement is subject to certain mandatory prepayments, including an amount equal to 50% of excess cash flow (as defined in the Credit Agreement) on an annual basis and the proceeds of certain asset sales, casualty events and issuances of indebtedness, subject to customary exceptions and reinvestment rights. The Credit Agreement includes two financial maintenance covenants which require the Borrowers to maintain a total leverage ratio (defined as the ratio of Consolidated Total Debt to Consolidated EBITDA (as these terms are defined in the Credit Agreement)) of 5.0:1 or less and a fixed charge coverage ratio (defined as the ratio of EBITDA minus capital expenditures to fixed charges (inclusive of rental expense and scheduled amortization)) of at least 1.5:1 , each as of the last day of each fiscal quarter. The Credit Agreement includes other affirmative and negative covenants and events of default that are customary for facilities of this type. The Credit Agreement contains, among other things, limitations on certain additional indebtedness and liens, and certain other transactions specified in the agreement. We were in compliance with all debt covenants as of December 31, 2017 . On June 16, 2016, the Borrowers issued $1.05 billion aggregate principal amount of 5.00% Senior Unsecured Notes due 2024 and $1.05 billion aggregate principal amount of 5.25% Senior Unsecured Notes due 2026 (together, the “Subsidiary Senior Unsecured Notes”). Interest on each series of Subsidiary Senior Unsecured Notes is payable semi-annually in arrears on June 1 and December 1, beginning on December 1, 2016. Additionally, on June 15, 2017, the Borrowers issued $750 million aggregate principal amount of 4.75% Senior Notes due June 1, 2027 (the “2027 Notes”). Interest on the 2027 Notes is payable semi-annually in arrears on June 1 and December 1, beginning on December 1, 2017. The Subsidiary Senior Unsecured Notes are guaranteed on a senior unsecured basis by (i) the Company, (ii) the Specified Guarantors and (iii) by each of the Borrower's and the Specified Guarantors’ domestic subsidiaries that guarantees the Borrower's obligations under the Credit Agreement, except for any of the Company’s foreign subsidiaries. The indenture governing the Subsidiary Senior Unsecured Notes contains covenants and events of default that are customary for debt securities of this type. We were in compliance with all debt covenants as of December 31, 2017 . During 2016, the Company paid debt issuance costs of $56 million in connection with the issuance of the Credit Agreement and the Subsidiary Senior Unsecured Notes. During 2017, $32 million of fees related to the repricing of the Term Loan A, Term Loan B and Revolving Facilities and the issuance of the 2027 Notes were capitalized as debt issuance costs. The debt issuance costs are being amortized to Interest expense, net through the contractual maturity of the agreements utilizing the effective interest rate method. We classify these deferred costs on our Consolidated Balance Sheet as a reduction in the related debt when borrowings are outstanding or within Other assets if borrowings are not outstanding. Additionally, $8 million of fees and unamortized debt issuance costs were recognized within Interest expense, net due to the repricings in the year ended December 31, 2017. As of December 31, 2017, the effective interest rates, including the amortization of debt issuance costs and the impact of the interest rate swaps on Term Loan B Facility (See Note 13), were 5.16% , 5.39% , 4.90% , 3.24% , and 3.82% for the Subsidiary Senior Unsecured Notes due 2024, the Subsidiary Senior Unsecured Notes due 2026, the Subsidiary Senior Unsecured Notes due 2027, the Term Loan A Facility, and the Term Loan B Facility, respectively. YUM Senior Unsecured Notes The majority of our remaining long-term debt primarily comprises YUM Senior Unsecured Notes with varying maturity dates from 2019 through 2043 and stated interest rates ranging from 3.75% to 6.88% . The YUM Senior Unsecured Notes represent senior, unsecured obligations and rank equally in right of payment with all of our existing and future unsecured unsubordinated indebtedness. Our YUM Senior Unsecured Notes contain cross-default provisions whereby the acceleration of the maturity of any of our indebtedness in a principal amount in excess of $50 million will constitute a default under the YUM Senior Unsecured Notes unless such indebtedness is discharged, or the acceleration of the maturity of that indebtedness is annulled, within 30 days after notice. The following table summarizes all YUM Senior Unsecured Notes issued that remain outstanding at December 31, 2017 : Interest Rate Issuance Date (a) Maturity Date Principal Amount (in millions) Stated Effective (b) October 2007 March 2018 $ 325 6.25 % 6.36 % October 2007 November 2037 325 6.88 % 7.45 % August 2009 September 2019 250 5.30 % 5.59 % August 2010 November 2020 350 3.88 % 4.01 % August 2011 November 2021 350 3.75 % 3.88 % October 2013 November 2023 325 3.88 % 4.01 % October 2013 November 2043 275 5.35 % 5.42 % (a) Interest payments commenced approximately six months after issuance date and are payable semi-annually thereafter.

Leases [Abstract]
Leases	Leases At December 31, 2017 , we operated 1,481 restaurants, leasing the underlying land and/or building in approximately 900 of those restaurants with the vast majority of our commitments expiring within 20 years from the inception of the lease. In addition, the Company leases or subleases approximately 900 units to franchisees, principally in the U.S., United Kingdom, Germany, Australia and France. We also lease office space for headquarters and support functions, as well as certain office and restaurant equipment. We do not consider any of these individual leases material to our operations. Most leases require us to pay related executory costs, which include property taxes, maintenance and insurance. Future minimum commitments and amounts to be received as lessor or sublessor under non cancelable leases are set forth below: Commitments Lease Receivables Capital Operating Direct Financing Operating 2018 $ 13 $ 124 $ 5 $ 64 2019 13 111 4 58 2020 12 87 4 51 2021 11 75 3 47 2022 11 67 3 44 Thereafter 76 435 24 415 $ 136 $ 899 $ 43 $ 679 At December 31, 2017 and December 31, 2016 , the present value of minimum payments under capital leases was $105 million and $120 million , respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Derivative Instruments We use derivative instruments to manage certain of our market risks related to fluctuations in interest rates and foreign currency exchange rates. Interest Rate Swaps We have entered into interest rate swaps with the objective of reducing our exposure to interest rate risk for our variable-rate debt interest payments related to $1.55 billion of our Term Loan B Facility, resulting in a fixed rate of 3.92% on the swapped portion of the Term Loan B Facility. These interest rate swaps will expire in July 2021 and the notional amount, maturity date and variable rate of these swaps match those of the related debt. These interest rate swaps are designated cash flow hedges as the changes in the future cash flows of the swaps are expected to offset changes in interest payments on the related variable-rate debt. There were no other interest rate swaps outstanding as of December 31, 2017. The effective portion of gains or losses on the interest rate swaps is reported as a component of AOCI and reclassified into Interest expense, net in our Consolidated Statement of Income in the same period or periods during which the related hedged interest payments affect earnings. Gains or losses on the swaps representing hedge ineffectiveness are recognized in current earnings. As of December 31, 2017, the swaps were highly effective cash flow hedges and no ineffectiveness has been recorded. Foreign Currency Contracts We have entered into foreign currency forward and swap contracts with the objective of reducing our exposure to earnings volatility arising from foreign currency fluctuations associated with certain foreign currency denominated intercompany receivables and payables. The notional amount, maturity date, and currency of these contracts match those of the underlying intercompany receivables or payables. Our foreign currency contracts are designated cash flow hedges as the future cash flows of the contracts are expected to offset changes in intercompany receivables and payables due to foreign currency exchange rate fluctuations. The effective portion of gains or losses on the foreign currency contracts is reported as a component of AOCI. Amounts are reclassified from AOCI each quarter to offset foreign currency transaction gains or losses recorded within Other (income) expense when the related intercompany receivables and payables affect earnings due to their functional currency remeasurements. Gains or losses on the foreign currency contracts representing hedge ineffectiveness are recognized in current earnings. As of December 31, 2017, all foreign currency contracts outstanding have been highly effective cash flow hedges and no ineffectiveness has been recorded. As of December 31, 2017 and December 31, 2016, foreign currency forward and swap contracts outstanding had total notional amounts of $456 million and $437 million , respectively. As of December 31, 2017, we have foreign currency forward and swap contracts with durations expiring as early as February 2018 and as late as 2020. As a result of the use of derivative instruments, the Company is exposed to risk that the counterparties will fail to meet their contractual obligations. To mitigate the counterparty credit risk, we only enter into contracts with carefully selected major financial institutions based upon their credit ratings and other factors, and continually assess the creditworthiness of counterparties. At December 31, 2017, all of the counterparties to our interest rate swaps and foreign currency contracts had investment grade ratings according to the three major ratings agencies. To date, all counterparties have performed in accordance with their contractual obligations.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	Fair Value Disclosures As of December 31, 2017 the carrying values of cash and cash equivalents, restricted cash, short-term investments, accounts receivable, and accounts payable approximated their fair values because of the short-term nature of these instruments. The fair value of notes receivable net of allowances and lease guarantees less subsequent amortization approximates their carrying value. The following table presents the carrying value and estimated fair value of the Company’s debt obligations: 12/31/2017 12/31/2016 Carrying Value Fair Value (Level 2) Carrying Value Fair Value (Level 2) Debt obligations Securitization Notes (a) $ 2,271 $ 2,367 $ 2,294 $ 2,315 Subsidiary Senior Unsecured Notes (b) 2,850 2,983 2,100 2,175 Term Loan A Facility (b) 500 503 500 501 Term Loan B Facility (b) 1,975 1,990 1,990 2,016 YUM Senior Unsecured Notes (b) 2,200 2,277 2,200 2,216 (a) We estimated the fair value of the Securitization Notes by obtaining broker quotes from two separate brokerage firms that are knowledgeable about the Company’s Securitization Notes and, at times, trade these notes. The markets in which the Securitization Notes trade are not considered active markets. (b) We estimated the fair value of the YUM and Subsidiary Senior Unsecured Notes, Term Loan A Facility, and Term Loan B Facility using market quotes and calculations based on market rates. Recurring Fair Value Measurements The Company has interest rate swaps, foreign currency forwards and swaps accounted for as cash flow hedges and other investments, all of which are required to be measured at fair value on a recurring basis (See Note 13 for discussion regarding derivative instruments). The following table presents fair values for those assets and liabilities measured at fair value on a recurring basis and the level within the fair value hierarchy in which the measurements fall. No transfers among the levels within the fair value hierarchy occurred during the years ended December 31, 2017 or December 31, 2016. Fair Value Level 2017 2016 Consolidated Balance Sheet Interest Rate Swaps - Liability 2 $ — $ 3 Accounts payable and other current liabilities Interest Rate Swaps - Asset 2 9 — Prepaid expenses and other current assets Interest Rate Swaps - Asset 2 40 47 Other assets Foreign Currency Contracts - Liability 2 46 — Other Liabilities and deferred credits Foreign Currency Contracts - Asset 2 5 6 Prepaid expenses and other current assets Foreign Currency Contracts - Asset 2 — 10 Other assets Other Investments 1 29 24 Other assets The fair value of the Company’s foreign currency forwards and swaps and interest rate swaps were determined based on the present value of expected future cash flows considering the risks involved, including nonperformance risk, and using discount rates appropriate for the duration based upon observable inputs. The other investments include investments in mutual funds, which are used to offset fluctuations in deferred compensation liabilities that employees have chosen to invest in phantom shares of a Stock Index Fund or Bond Index Fund. The other investments are classified as trading securities in Other assets in our Consolidated Balance Sheet and their fair value is determined based on the closing market prices of the respective mutual funds as of December 31, 2017 and December 31, 2016. Non-Recurring Fair Value Measurements The following table presents expense recognized from all non-recurring fair value measurements during the years ended December 31, 2017 and December 31, 2016. These amounts exclude fair value measurements made for assets that were subsequently dispo sed of prior to those respective year end dates. The remaining net book value of restaurant assets measured at fair value during the years ended December 31, 2017 and December 31, 2016 is insignificant. 2017 2016 Aircraft impairment (a) $ — $ 3 Restaurant-level impairment (b) 2 9 Total $ 2 $ 12 (a) During 2016, we made the decision to dispose of a corporate aircraft.

Retirement Benefits [Abstract]
Retiree Medical Benefits	Pension, Retiree Medical and Retiree Savings Plans U.S. Pension Plans We sponsor qualified and supplemental (non-qualified) noncontributory defined benefit plans covering certain full-time salaried and hourly U.S. employees. The qualified plan meets the requirements of certain sections of the Internal Revenue Code and provides benefits to a broad group of employees with restrictions on discriminating in favor of highly compensated employees with regard to coverage, benefits and contributions. The supplemental plans provide additional benefits to certain employees. We fund our supplemental plans as benefits are paid. The most significant of our U.S. plans is the YUM Retirement Plan (the “Plan”), which is a qualified plan. Our funding policy with respect to the Plan is to contribute amounts necessary to satisfy minimum pension funding requirements, including requirements of the Pension Protection Act of 2006, plus additional amounts from time-to-time as are determined to be necessary to improve the Plan’s funded status. We do not expect to make any significant contributions to the Plan in 2018. Our two significant U.S. plans were previously amended such that any salaried employee hired or rehired by YUM after September 30, 2001 is not eligible to participate in those plans. During the fourth quarter of 2016, the Company allowed certain former employees with deferred vested balances in the Plan an opportunity to voluntarily elect an early payout of their benefits. See Note 5 for details. We do not anticipate any plan assets being returned to the Company during 2018 for any U.S. plans. Obligation and Funded Status at Measurement Date: The following chart summarizes the balance sheet impact, as well as benefit obligations, assets, and funded status associated with our two significant U.S. pension plans. The actuarial valuations for all plans reflect measurement dates coinciding with our fiscal year end. 2017 2016 Change in benefit obligation: Benefit obligation at beginning of year $ 993 $ 1,134 Service cost 10 17 Interest cost 41 54 Plan amendments 2 4 Curtailments (2 ) (4 ) Special termination benefits 2 3 Benefits paid (76 ) (26 ) Settlement payments (a) (73 ) (260 ) Actuarial (gain) loss 115 77 Administrative expense (5 ) (6 ) Benefit obligation at end of year $ 1,007 $ 993 Change in plan assets: Fair value of plan assets at beginning of year $ 837 $ 1,004 Actual return on plan assets 129 87 Employer contributions 52 38 Settlement payments (a) (73 ) (260 ) Benefits paid (76 ) (26 ) Administrative expenses (5 ) (6 ) Fair value of plan assets at end of year $ 864 $ 837 Funded status at end of year $ (143 ) $ (156 ) (a) For discussion of the settlement payments made in connection with the deferred vested program in 2016, see Note 5.

Weighted-average assumptions used to determine benefit obligations at the measurement dates: 2017 2016 Discount rate 3.90 % 4.60 % Rate of compensation increase 3.75 % 3.75 % Weighted-average assumptions used to determine the net periodic benefit cost for fiscal years: 2017 (a) 2016 2015 Discount rate 4.53 % 4.90 % 4.30 % Long-term rate of return on plan assets 6.06 % 6.75 % 6.75 % Rate of compensation increase 3.75 % 3.75 % 3.75 % (a) Reflects a weighted average due to interim remeasurements in 2017. Our estimated long-term rate of return on plan assets represents the weighted-average of expected future returns on the asset categories included in our target investment allocation based primarily on the historical returns for each asset category and future growth expectations. Plan Assets The fair values of our pension plan assets at December 31, 2017 and December 31, 2016 by asset category and level within the fair value hierarchy are as follows: 2017 2016 Level 1: Cash $ 3 $ 2 Cash Equivalents (a) 12 12 Fixed Income Securities - U.S. Corporate (b) 177 172 Equity Securities – U.S. Large cap (b) 257 244 Equity Securities – U.S. Mid cap (b) 43 41 Equity Securities – U.S. Small cap (b) 43 43 Equity Securities – Non-U.S. (b) 87 83 Level 2: Fixed Income Securities – U.S. Corporate (c) 86 76 Fixed Income Securities – U.S. Government and Government Agencies (d) 177 152 Fixed Income Securities – Other (d) 35 31 Total fair value of plan assets (e) $ 920 $ 856 (a) Short-term investments in money market funds. (b) Securities held in common trusts. (c) Investments held directly by the Plan. (d) Includes securities held in common trusts and investments held directly by the Plan. (e) 2017 and 2016 exclude net unsettled trade payables of $56 million and $19 million , respectively. Our primary objectives regarding the investment strategy for the Plan’s assets are to reduce interest rate and market risk and to provide adequate liquidity to meet immediate and future payment requirements. To achieve these objectives, we are using a combination of active and passive investment strategies. The Plan's equity securities, currently targeted to be 50% of our investment mix, consist primarily of low-cost index funds focused on achieving long-term capital appreciation. The Plan diversifies its equity risk by investing in several different U.S. and foreign market index funds. Investing in these index funds provides the Plan with the adequate liquidity required to fund benefit payments and plan expenses. The fixed income asset allocation, currently targeted to be 50% of our mix, is actively managed and consists of long-duration fixed income securities that help to reduce exposure to interest rate variation and to better correlate asset maturities with obligations. The fair values of all pension plan assets are determined based on closing market prices or net asset values. A mutual fund held as an investment by the Plan includes shares of Common Stock valued at $0.3 million at both December 31, 2017 and December 31, 2016 (less than 1% of total plan assets in each instance). Benefit Payments The benefits expected to be paid in each of the next five years and in the aggregate for the five years thereafter are set forth below: Year ended: 2018 $ 65 2019 37 2020 39 2021 42 2022 44 2023 - 2027 257 Expected benefit payments are estimated based on the same assumptions used to measure our benefit obligation on the measurement date and include benefits attributable to estimated future employee service. International Pension Plans We also sponsor various defined benefit plans covering certain of our non-U.S. employees, the most significant of which are in the UK. Both of our UK plans have previously been frozen such that they are closed to new participants and existing participants can no longer earn future service credits. At the end of 2017 and 2016, the projected benefit obligations of these UK plans totaled $287 million and $261 million , respectively and plan assets totaled $358 million and $305 million , respectively. These plans were both in a net overfunded position at the end of 2017 and 2016 and related expense amounts recorded in each of 2017, 2016 and 2015 were not significant. The funding rules for our pension plans outside of the U.S. vary from country to country and depend on many factors including discount rates, performance of plan assets, local laws and regulations. We do not plan to make significant contributions to either of our UK plans in 2018. Retiree Medical Benefits Our post-retirement plan provides health care benefits, principally to U.S. salaried retirees and their dependents, and includes retiree cost-sharing provisions. This plan was previously amended such that any salaried employee hired or rehired by YUM after September 30, 2001 is not eligible to participate in this plan. Employees hired prior to September 30, 2001 are eligible for benefits if they meet age and service requirements and qualify for retirement benefits. We fund our post-retirement plan as benefits are paid. At the end of both 2017 and 2016 , the accumulated post-retirement benefit obligation was $55 million . Actuarial gains of $8 million and $10 million were recognized in AOCI at the end of 2017 and 2016 , respectively. The net periodic benefit cost recorded was $2 million in 2017 and $3 million in both 2016 and 2015 , the majority of which is interest cost on the accumulated post-retirement benefit obligation. The weighted-average assumptions used to determine benefit obligations and net periodic benefit cost for the post-retirement medical plan are identical to those as shown for the U.S. pension plans. Our assumed heath care cost trend rates for the following year as of 2017 and 2016 are 6.3% and 6.6% , respectively, with expected ultimate trend rates of 4.5% reached in 2038. There is a cap on our medical liability for certain retirees. The cap for Medicare-eligible retirees was reached in 2000 and the cap for non-Medicare eligible retirees was reached in 2014; with the cap, our annual cost per retiree will not increase. A one-percentage-point increase or decrease in assumed health care cost trend rates would have no impact on total service and interest cost or on the post-retirement benefit obligation. The benefits expected to be paid in each of the next five years are approximately $5 million and in aggregate for the five years thereafter are $17 million . Retiree Savings Plan We sponsor a contributory plan to provide retirement benefits under the provisions of Section 401(k) of the Internal Revenue Code (the “401(k) Plan”) for eligible U.S. salaried and hourly employees. Participants are able to elect to contribute up to 75% of eligible compensation on a pre-tax basis. Participants may allocate their contributions to one or any combination of multiple investment options or a self-managed account within the 401(k) Plan. We match 100% of the participant’s contribution to the 401(k) Plan up to 6% of eligible compensation. We recognized as compensation expense our total matching contribution of $13 million in 2017 , $14 million in 2016 and $13 million in 2015

Share-based and Deferred Compen

Share-based and Deferred Compensation Plans	Dec. 31, 2017
Compensation Related Costs [Abstract]
Share-based and Deferred Compensation Plans	Share-based and Deferred Compensation Plans Overview At year end 2017, we had one stock award plan in effect: the YUM! Brands, Inc. Long-Term Incentive Plan (the “LTIP”). Under the LTIP, the exercise price of stock options and SARs granted must be equal to or greater than the average market price or the ending market price of the Company’s stock on the date of grant. Potential awards to employees and non-employee directors under the LTIP include stock options, incentive stock options, SARs, restricted stock, restricted stock units (“RSUs”), performance restricted stock units, performance share units (“PSUs”) and performance units. We have issued only stock options, SARs, RSUs and PSUs under the LTIP. While awards under the LTIP can have varying vesting provisions and exercise periods, outstanding awards under the LTIP vest in periods ranging from immediate to five years. Stock options and SARs expire ten years after grant. At year end 2017 , approximately 28 million shares were available for future share-based compensation grants under the LTIP. Our EID Plan allows participants to defer receipt of a portion of their annual salary and all or a portion of their incentive compensation. As defined by the EID Plan, we credit the amounts deferred with earnings based on the investment options selected by the participants. These investment options are limited to cash, phantom shares of our Common Stock, phantom shares of a Stock Index Fund and phantom shares of a Bond Index Fund. Investments in cash and phantom shares of both index funds will be distributed in cash at a date as elected by the employee and therefore are classified as a liability on our Consolidated Balance Sheets. We recognize compensation expense for the appreciation or the depreciation, if any, of investments in cash and both of the index funds. Deferrals into the phantom shares of our Common Stock will be distributed in shares of our Common Stock, under the LTIP, at a date as elected by the employee and therefore are classified in Common Stock on our Consolidated Balance Sheets. We do not recognize compensation expense for the appreciation or the depreciation, if any, of investments in phantom shares of our Common Stock. Our EID plan also allows certain participants to defer incentive compensation to purchase phantom shares of our Common Stock and receive a 33% Company match on the amount deferred. Deferrals receiving a match are similar to a RSU award in that participants will generally forfeit both the match and incentive compensation amounts deferred if they voluntarily separate from employment during a vesting period that is two years from the date of deferral. We expense the intrinsic value of the match and the incentive compensation over the requisite service period which includes the vesting period. Historically, the Company has repurchased shares on the open market in excess of the amount necessary to satisfy award exercises and expects to continue to do so in 2018. In connection with the Separation of our China business in the prior year, under the provisions of our LTIP, employee stock options, SARs, RSUs and PSUs were adjusted to maintain the pre-spin intrinsic value of the awards. Depending on the tax laws of the country of employment, awards were modified using either the shareholder method or the employer method. Share issuances for Yum China awards held by YUM employees will be satisfied by Yum China. Share issuances for YUM awards held by Yum China employees are being satisfied by YUM. Share-based compensation as recorded in Income from continuing operations is based on the amortization of the fair value for both YUM and Yum China awards held by YUM employees. The shareholder method was based on the premise that employees holding YUM awards prior to the Separation should receive an equal number of awards of both YUM and Yum China. For stock options and SARs, exercise prices of these post-Separation YUM and Yum China awards were established that, on a combined basis, maintained the intrinsic value on the YUM award prior to the Separation. The exercise prices provided for an initial intrinsic value in each of the post-Separation YUM and YUM China awards that was proportionate to the market value of the two companies on November 1, 2016. For RSUs and PSUs modified under the shareholder method, each YUM award was modified into one YUM award and one Yum China award. Under the employer method, employees holding YUM awards prior to the Separation had their awards converted into awards of the company that they worked for subsequent to the Separation. For stock options and SARs modified under the employer method, the exercise prices of the awards were modified to maintain the pre-Separation intrinsic value of the awards in relation to the post-Separation stock price of the applicable company . For RSUs and PSUs modified under the employer method, the number of awards was modified to maintain the pre-Separation intrinsic value of the awards in relation to the post-Separation stock price of the applicable company . The modifications to the outstanding equity awards resulted in an insignificant amount of additional compensation expense in the year ended December 31, 2016. Investments in phantom shares of our Common Stock held within our EID Plan by employees that remained with YUM post-Separation that were converted into phantom investments in Yum China at Separation under the shareholder method are allowed to be transferred into cash, phantom shares of a Stock Index Fund and phantom shares of a Bond Index Fund within the EID Plan. As such, distributions of current investments in phantom shares of Yum China may now be settled in cash, as opposed to stock, at a date as elected by the employee and, therefore, are classified as a liability and remeasured to fair value at each reporting period in our Consolidated Balance Sheet. During 2017 and 2016, we recorded $18 million and $30 million , respectively, within G&A related to these awards (See Note 5). Award Valuation We estimated the fair value of each stock option and SAR award as of the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions: 2017 2016 2015 Risk-free interest rate 1.9 % 1.4 % 1.3 % Expected term (years) 6.4 years 6.4 years 6.4 years Expected volatility 22.9 % 27.0 % 26.9 % Expected dividend yield 1.8 % 2.6 % 2.2 % We believe it is appropriate to group our stock option and SAR awards into two homogeneous groups when estimating expected term. These groups consist of grants made primarily to restaurant-level employees, which cliff-vest after 4 years and expire 10 years after grant, and grants made to executives, which typically have a graded vesting schedule of 25% per year over 4 years and expire 10 years after grant. We use a single weighted-average term for our awards that have a graded vesting schedule. Based on analysis of our historical exercise and post-vesting termination behavior, we have determined that our restaurant-level employees and our executives exercised the awards on average after 5 years and 6.5 years, respectively. When determining expected volatility, we consider both historical volatility of our stock as well as implied volatility associated with our publicly traded options. The expected dividend yield is based on the annual dividend yield at the time of grant. The fair values of RSU awards are based on the closing price of our Common Stock on the date of grant. The fair values of PSU awards with market-based conditions have been valued based on the outcome of a Monte Carlo simulation. Award Activity Stock Options and SARs Shares (in thousands) Weighted-Average Exercise Price Weighted- Average Remaining Contractual Term (years) Aggregate Intrinsic Value (in millions) Outstanding at the beginning of the year 21,242 $ 40.78 Granted 2,879 67.93 Exercised (4,269 ) 36.45 Forfeited or expired (1,567 ) 54.98 Outstanding at the end of the year 18,285 (a) 44.85 5.42 $ 672 Exercisable at the end of the year 11,971 $ 38.07 4.00 $ 521 (a) Outstanding awards include 943 options and 17,342 SARs with weighted average exercise prices of $36.63 and $45.30 , respectively. Outstanding awards represent YUM awards held by employees of both YUM and Yum China. The weighted-average grant-date fair value of stock options and SARs granted during 2017 , 2016 and 2015 was $14.08 , $14.40 and $15.95 , respectively. The total intrinsic value of stock options and SARs exercised during the years ended December 31, 2017 , December 31, 2016 and December 31, 2015 , was $154 million , $263 million and $153 million , respectively. As of December 31, 2017 , $55 million of unrecognized compensation cost related to unvested stock options and SARs, which will be reduced by any forfeitures that occur, is expected to be recognized over a remaining weighted-average period of approximately 1.8 years. This reflects unrecognized cost for both YUM and Yum China awards held by YUM employees. The total fair value at grant date of awards for both YUM and Yum China awards held by YUM employees that vested during 2017 , 2016 and 2015 was $33 million , $41 million and $42 million , respectively. RSUs and PSUs As of December 31, 2017 , there was $20 million of unrecognized compensation cost related to 1.0 million unvested RSUs and PSUs. The total fair value at grant date of awards that vested during 2017, 2016 and 2015 was $10 million , $7 million and $11 million , respectively. Impact on Net Income The components of share-based compensation expense and the related income tax benefits are shown in the following table: 2017 2016 2015 Options and SARs $ 30 $ 38 $ 41 Restricted Stock Units 26 38 3 Performance Share Units 9 4 2 Total Share-based Compensation Expense $ 65 (a) $ 80 (b) $ 46 Deferred Tax Benefit recognized $ 22 (c) $ 26 $ 15 EID compensation expense not share-based $ 12 $ 5 $ 1 (a) Includes $18 million due to appreciation in the market price of Yum China's stock.

(c) Deferred tax benefit recognized does not reflect the impact of the Tax Act. See Note 18. Cash received from stock option exercises for 2017 , 2016 and 2015 , was $12 million , $5 million and $12 million , respectively. Tax benefits realized on our tax returns from tax deductions associated with share-based compensation for 2017 , 2016 and 2015 totaled $153 million , $109 million and $62 million , respectively.

This item includes local taxes, withholding taxes, and shareholder-level taxes, net of foreign tax credits. The favorable impact is primarily attributable to a majority of our income being earned outside of the U.S. where tax rates are generally lower than the U.S. rate. In 2015, this benefit was positively impacted by the repatriation of current year foreign earnings as we recognized excess foreign tax credits, resulting from the related effective foreign tax rate being higher than the U.S. federal statutory rate. Adjustments to reserves and prior years. This item includes: (1) changes in tax reserves, including interest thereon, established for potential exposure we may incur if a taxing authority takes a position on a matter contrary to our position; and (2) the effects of reconciling income tax amounts recorded in our Consolidated Statements of Income to amounts reflected on our tax returns, including any adjustments to the Consolidated Balance Sheets. The impact of certain effects or changes may offset items reflected in the 'Statutory rate differential attributable to foreign operations' line. In 2016, this item was favorably impacted by the resolution of uncertain tax positions in the U.S. Share-based payments. 2017 includes a $117 million tax benefit related to the excess tax benefits from share-based payments. These excess benefits were largely associated with deferred compensation payouts to recently retired employees. See Note 2 for discussion related to the adoption of a new accounting standard for share based payments in 2017. Change in valuation allowances. This item relates to changes for deferred tax assets generated or utilized during the current year and changes in our judgment regarding the likelihood of using deferred tax assets that existed at the beginning of the year. The impact of certain changes may offset items reflected in the 'Statutory rate differential attributable to foreign operations' line. In 2017, $34 million of net tax expense was driven by valuation allowances recorded against deferred tax assets generated in the current year. This amount excludes a valuation allowance of $189 million related to the Tax Act. In 2016, $3 million of net tax benefit was driven by $14 million in net tax expense for valuation allowances recorded against deferred tax assets generated in the current year and $17 million in net tax benefit for valuation allowances resulting from a change in judgment regarding the future use of certain deferred tax assets that existed at the beginning of the year. In 2015, $41 million of net tax expense was driven by $17 million for valuation allowances recorded against deferred tax assets generated in the current year and $24 million in net tax expense resulting from a change in judgment regarding the future use of certain deferred tax assets that existed at the beginning of the year. Other. This item primarily includes the impact of permanent differences related to current year earnings as well as U.S. tax credits and deductions. In 2017, this item was primarily driven by the favorable impact of certain international refranchising gains. Tax Act Enactment. On December 22, 2017, the U.S. government enacted comprehensive Federal tax legislation commonly referred to as the Tax Cuts and Jobs Act of 2017 (the "Tax Act"). The Tax Act significantly modifies the U.S. corporate income tax system by, among other things, reducing the federal income tax rate from 35% to 21% , limiting certain deductions, including limiting the deductibility of interest expense to 30% of U.S. Earnings Before Interest, Taxes, Depreciation and Amortization, imposing a mandatory one-time deemed repatriation tax on accumulated foreign earnings and creating a territorial tax system that changes the manner in which future foreign earnings are subject to U.S. tax. On December 22, 2017, the SEC staff issued Staff Accounting Bulletin 118 that allows us to record provisional amounts related to the impacts of the Tax Act during a measurement period not to extend beyond one year of the enactment date. We currently are analyzing the Tax Act and have made reasonable estimates of the effects on our Consolidated Financial Statements and tax disclosures, including the amount of the deemed repatriation tax and changes to our existing deferred tax balances. The deemed repatriation tax is based on our accumulated foreign earnings and profits that we previously deferred from U.S. income taxes. We recorded an estimated amount for our repatriation tax liability of $170 million as of December 31, 2017. In addition, we remeasured certain net deferred tax assets and liabilities based on the tax rates at which they are expected to reverse in the future. The estimated amount recorded related to the remeasurement of these balances was a net expense of $75 million . Lastly, we recorded a valuation allowance of $189 million on our remaining foreign tax credit carryforwards which are unlikely to be realized under the U.S. territorial tax system. The estimated total impact upon enactment of the Tax Act is $434 million . We consider the key estimates on the deemed repatriation tax, net deferred tax remeasurement and the impact on our foreign tax credit carryforwards to be incomplete due to our continuing analysis of final year-end data and tax positions. Our analysis could affect the measurement of these balances and give rise to new deferred and other tax assets and liabilities. Since the Tax Act was passed late in the fourth quarter of 2017, and further guidance and accounting interpretation is expected over the next 12 months, our review is still pending. We expect to complete our analysis of the amounts recorded upon enactment of the Tax Act within the measurement period of one year. The details of 2017 and 2016 deferred tax assets (liabilities) are set forth below: 2017 2016 Operating losses $ 216 $ 172 Capital losses 4 184 Tax credit carryforwards 311 284 Employee benefits 94 185 Share-based compensation 58 100 Self-insured casualty claims 7 32 Lease-related liabilities 51 65 Various liabilities 51 56 Property, plant and equipment 24 37 Deferred income and other 31 32 Gross deferred tax assets 847 1,147 Deferred tax asset valuation allowances (421 ) (195 ) Net deferred tax assets $ 426 $ 952 Intangible assets, including goodwill $ (69 ) $ (107 ) Property, plant and equipment (18 ) (46 ) Deemed repatriation tax (170 ) — Other (36 ) (34 ) Gross deferred tax liabilities $ (293 ) $ (187 ) Net deferred tax assets (liabilities) $ 133 $ 765 Reported in Consolidated Balance Sheets as: Deferred income taxes $ 139 $ 772 Other liabilities and deferred credits (6 ) (7 ) $ 133 $ 765 As of December 31, 2017, we had approximately $3.2 billion of unremitted foreign earnings. We have historically reinvested all the unremitted earnings of our foreign subsidiaries and affiliates, and therefore have not recognized any U.S. deferred tax liability on these earnings. However, upon the enactment of the Tax Act, the unremitted earnings of our foreign subsidiaries and affiliates are subject to U.S. tax due to the mandatory deemed repatriation tax on accumulated foreign earnings provision. As a result, we recognized a one-time income tax expense of $170 million . Our intent is to indefinitely reinvest our unremitted earnings outside the U.S. and our current plans do not demonstrate a need to repatriate these amounts to fund our U.S. operations. Thus, for our investments in foreign subsidiaries where the carrying values for financial reporting exceed the tax basis, we have not provided taxes, other than U.S. federal taxes, for the portion of the excess that we believe is permanently invested, as we have the ability and intent to indefinitely postpone these basis differences from reversing with a tax consequence. However, if these funds were repatriated, we would be required to accrue and pay applicable income taxes (if any) and withholding taxes payable to various countries. A determination of the deferred tax liability on this amount is not practicable. At December 31, 2017 , the Company has foreign operating and capital loss carryforwards of $0.5 billion and U.S. state operating loss and tax credit carryforwards of $1.1 billion and U.S. federal tax credit carryforwards of $0.3 billion . A valuation allowance of $434 million has been recorded against the carryforwards that are not likely to be realized. These losses are being carried forward in jurisdictions where we are permitted to use tax losses from prior periods to reduce future taxable income and will expire as follows: Year of Expiration 2018 2019-2022 2023-2036 Indefinitely Total Foreign $ 9 $ 46 $ 85 $ 376 $ 516 U.S. state — 61 1,012 — 1,073 U.S. federal — 67 238 — 305 $ 9 $ 174 $ 1,335 $ 376 $ 1,894 We recognize the benefit of positions taken or expected to be taken in tax returns in the Consolidated Financial Statements when it is more likely than not that the position would be sustained upon examination by tax authorities. A recognized tax position is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon settlement. The Company had $100 million and $91 million of unrecognized tax benefits at December 31, 2017 and December 31, 2016 , respectively, $10 million and $87 million of which are temporary in nature and if recognized, would not impact the effective income tax rate. A reconciliation of the beginning and ending amount of unrecognized tax benefits follows: 2017 2016 Beginning of Year $ 91 $ 98 Additions on tax positions - current year 3 — Additions for tax positions - prior years 8 1 Reductions for tax positions - prior years — (5 ) Reductions for settlements (1 ) (1 ) Reductions due to statute expiration (1 ) (2 ) Foreign currency translation adjustment — — End of Year $ 100 $ 91 The Company believes its unrecognized tax benefits will not materially increase or decrease in the next 12 months. The Company’s income tax returns are subject to examination in the U.S. federal jurisdiction and numerous U.S. state and foreign jurisdictions. The Company has settled audits with the IRS through fiscal year 2010. Our operations in certain foreign jurisdictions remain subject to examination for tax years as far back as 2006, some of which years are currently under audit by local tax authorities. The accrued interest and penalties related to income taxes at December 31, 2017 and December 31, 2016 are set forth below: 2017 2016 Accrued interest and penalties $ 14 $ 9 During 2017 , 2016 and 2015 , a net expense of $5 million , a net benefit of $4 million and a net expense of $5 million , respectively, for interest and penalties was recognized in our Consolidated Statements of Income as components of its Income tax provision.

Contingencies

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Lease Guarantees As a result of having assigned our interest in obligations under real estate leases as a condition to the refranchising of certain Company-owned restaurants, and guaranteeing certain other leases, we are frequently contingently liable on lease agreements. These leases have varying terms, the latest of which expires in 2065. As of December 31, 2017 , the potential amount of undiscounted payments we could be required to make in the event of non-payment by the primary lessee was approximately $600 million . The present value of these potential payments discounted at our pre-tax cost of debt at December 31, 2017 was approximately $500 million . Our franchisees are the primary lessees under the vast majority of these leases. We generally have cross-default provisions with these franchisees that would put them in default of their franchise agreement in the event of non-payment under the lease. We believe these cross-default provisions significantly reduce the risk that we will be required to make payments under these leases. Accordingly, the liability recorded for our probable exposure under such leases at December 31, 2017 and December 31, 2016 was not material. Franchise Loan Pool and Equipment Guarantees We have agreed to provide financial support, if required, to a variable interest entity that operates a franchisee lending program used primarily to assist franchisees in the development of new restaurants or the upgrade of existing restaurants and, to a lesser extent, in connection with the Company’s refranchising programs in the U.S. We have determined that we are not required to consolidate this entity as we share the power to direct this entity’s lending activity with other parties. We have provided guarantees of 20% of the outstanding loans of the franchisee loan program. As such, at December 31, 2017 our guarantee exposure under this program is $3 million based on total loans outstanding of $15 million . In addition to the guarantees described above, YUM has agreed to provide guarantees of up to $43 million on behalf of franchisees for several financing programs related to equipment purchases and refranchising. At December 31, 2017 , our guarantee exposure under these financing programs is $10 million based on total loans outstanding of $31 million . Insurance Programs We are self-insured for a substantial portion of our current and prior years’ coverage including property and casualty losses. To mitigate the cost of our exposures for certain property and casualty losses, we self-insure the risks of loss up to defined maximum per occurrence retentions on a line-by-line basis. The Company then purchases insurance coverage, up to a certain limit, for losses that exceed the self-insurance per occurrence retention. The insurers’ maximum aggregate loss limits are significantly above our actuarially determined probable losses; therefore, we believe the likelihood of losses exceeding the insurers’ maximum aggregate loss limits is remote. The following table summarizes the 2017 and 2016 activity related to our net self-insured property and casualty reserves as of December 31, 2017 . Beginning Balance Expense Payments Ending Balance 2017 Activity $ 98 27 (41 ) $ 84 2016 Activity $ 102 42 (46 ) $ 98 Due to the inherent volatility of actuarially determined property and casualty loss estimates, it is reasonably possible that we could experience changes in estimated losses which could be material to our growth in quarterly and annual Net Income. We believe that we have recorded reserves for property and casualty losses at a level which has substantially mitigated the potential negative impact of adverse developments and/or volatility. In the U.S. and in certain other countries, we are also self-insured for healthcare claims and long-term disability for eligible participating employees subject to certain deductibles and limitations. We have accounted for our retained liabilities for property and casualty losses, healthcare and long-term disability claims, including reported and incurred but not reported claims, based on information provided by independent actuaries. Legal Proceedings We are subject to various claims and contingencies related to lawsuits, real estate, environmental and other matters arising in the normal course of business. An accrual is recorded with respect to claims or contingencies for which a loss is determined to be probable and reasonably estimable.

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2017
Accounting Policies [Abstract]
Principles of Consolidation and Basis of Preparation	Principles of Consolidation and Basis of Preparation. Intercompany accounts and transactions have been eliminated in consolidation. We consolidate entities in which we have a controlling financial interest, the usual condition of which is ownership of a majority voting interest. We also consider for consolidation an entity, in which we have certain interests, where the controlling financial interest may be achieved through arrangements that do not involve voting interests. Such an entity, known as a variable interest entity (“VIE”), is required to be consolidated by its primary beneficiary. The primary beneficiary is the entity that possesses the power to direct the activities of the VIE that most significantly impact its economic performance and has the obligation to absorb losses or the right to receive benefits from the VIE that are significant to it. Our most significant variable interests are in entities that operate restaurants under our Concepts’ franchise and license arrangements. We do not have an equity interest in any of our franchisee businesses. Additionally, we do not typically provide significant financial support such as loans or guarantees to our franchisees. However, we do have variable interests in certain franchisees through real estate lease arrangements to which we are a party. At the end of 2017 , YUM has future lease payments due from franchisees, on a nominal basis, of approximately $725 million , and we are contingently liable on certain other lease agreements that have been assigned to franchisees. See the Lease Guarantees and Franchise Loan Pool and Equipment Guarantees sections in Note 20. As our franchise and license arrangements provide our franchisee entities the power to direct the activities that most significantly impact their economic performance, we do not consider ourselves the primary beneficiary of any such entity that might otherwise be considered a VIE. See Note 20 for additional information on our entity that operates a franchise lending program that is a VIE in which we have a variable interest but for which we are not the primary beneficiary and thus do not consolidate.
Fiscal Year	Fiscal Year. Our fiscal years have historically ended on the last Saturday in December and, as a result, a 53 rd week was added every five or six years. The first three quarters of each fiscal year consisted of 12 weeks and the fourth quarter consisted of 16 weeks in fiscal years with 52 weeks and 17 weeks in fiscal years with 53 weeks. Our U.S. subsidiaries and certain international subsidiaries operated on similar fiscal calendars. Our remaining international subsidiaries operated on a monthly calendar, and thus never had a 53 rd week, with two months in the first quarter, three months in the second and third quarters and four months in the fourth quarter. Certain international subsidiaries within our KFC, Pizza Hut and Taco Bell divisions have historically closed approximately one month or one period earlier to facilitate consolidated reporting. Fiscal year 2016 included 53 weeks for our U.S. businesses and for our international subsidiaries that reported on a period calendar. The 53 rd week added $76 million to Total revenues and $28 million to Operating Profit in our 2016 Consolidated Statement of Income. On January 27, 2017, YUM’s Board of Directors approved a change in the Company's fiscal year from a year ending on the last Saturday of December to a year beginning on January 1 and ending December 31 of each year, commencing with the year ending December 31, 2017. In connection with this change, the Company moved from a 52-week periodic fiscal calendar with three 12-week interim quarters and a 16-week fourth quarter to a monthly reporting calendar with each quarter comprised of three months. Our U.S. subsidiaries continue to report on a period calendar as described above. Concurrent with the change in the Company's fiscal year, we also eliminated the one month or one period reporting lags of our international subsidiaries. As a result of removing these reporting lags, each international subsidiary operates either on a monthly calendar consistent with the Company’s new calendar or on a periodic calendar consistent with our U.S. subsidiaries. We believe this change in our international subsidiary reporting calendars and the resulting elimination of reporting lags is preferable because a more current reporting calendar allows the Consolidated Financial Statements to more consistently and more timely reflect the impact of current events, economic conditions and global trends.
Foreign Currency	Foreign Currency. The functional currency of our foreign entities is the currency of the primary economic environment in which the entity operates. Functional currency determinations are made based upon a number of economic factors, including but not limited to cash flows and financing transactions. The operations, assets and liabilities of our entities outside the U.S. are initially measured using the functional currency of that entity. Income and expense accounts for our operations of these foreign entities are then translated into U.S. dollars at the average exchange rates prevailing during the period. Assets and liabilities of these foreign entities are then translated into U.S. dollars at exchange rates in effect at the balance sheet date. As of December 31, 2017 , net cumulative translation adjustment losses of $174 million are recorded in Accumulated other comprehensive loss ("AOCI") in the Consolidated Balance Sheet. The majority of our foreign currency net asset exposure is in countries where we have Company-owned restaurants. As we manage and share resources at the individual brand level within a country, cumulative translation adjustments are recorded and tracked at the foreign-entity level that represents the operations of our individual brands within that country. Translation adjustments recorded in AOCI are subsequently recognized as income or expense generally only upon sale of the related investment in a foreign entity, or upon a sale of assets and liabilities within a foreign entity that represents a complete or substantially complete liquidation of that foreign entity. For purposes of determining whether a sale or complete or substantially complete liquidation of an investment in a foreign entity has occurred, we consider those same foreign entities for which we record and track cumulative translation adjustments.
Reclassifications	Reclassifications. We have reclassified certain items in the Consolidated Financial Statements for prior periods to be comparable with the classification for the fiscal year ended December 31, 2017
Franchise and License Operations	Franchise Operations. We execute store-level franchise agreements for units operated by third parties which set out the terms of our arrangement with the franchisee. Our franchise agreements typically require the franchisee to pay an initial, non-refundable fee upon an individual store opening and continuing fees based upon a percentage of sales. Subject to our approval and their payment of a renewal fee, a franchisee may generally renew the franchise agreement upon its expiration. Additionally, we execute master franchise agreements in certain regions that transfer administrative and development obligations and sub-franchising rights to a franchisee in exchange for reduced franchise fees.
Revenue Recognition	Revenue Recognition. Revenues from Company-owned restaurants are recognized when payment is tendered at the time of sale. The Company presents sales net of sales-related taxes. Income from our franchisees includes initial fees, continuing fees, renewal fees and rental income from restaurants we lease or sublease to them. We recognize initial fees received from a franchisee as revenue when we have performed substantially all initial services required by the franchise agreement, which is generally upon the opening of a store. We recognize continuing fees, which are based upon a percentage of franchisee sales as those sales occur and rental income is recognized as it is earned. We recognize renewal fees when a renewal agreement with a franchisee becomes effective.
Direct Marketing Costs	Direct Marketing Costs. To the extent we participate in advertising cooperatives, we expense our contributions as incurred which are based on a percentage of sales. We charge direct marketing costs incurred outside of a cooperative to expense ratably in relation to revenues over the year in which incurred and, in the case of advertising production costs, in the year the advertisement is first shown. Deferred direct marketing costs, which are classified as prepaid expenses, consist of media and related advertising production costs which will generally be used for the first time in the next fiscal year and have historically not been significant. Our advertising expenses were $245 million , $260 million and $253 million in 2017 , 2016 and 2015 , respectively. We report the majority of our direct marketing costs in Occupancy and other operating expenses as they are incurred as a percentage of sales by Company-owned restaurants. Advertising incurred on behalf of franchised restaurants is recorded within Franchise and license expenses, including $25 million related to the Pizza Hut U.S. Transformation Agreement and $20 million
Research and Development Expenses	Research and Development Expenses. Research and development expenses, which we expense as incurred, are reported in G&A. Research and development expenses were $22 million , $24 million and $23 million in 2017 , 2016 and 2015 , respectively.
Share-Based Employee Compensation	Share-Based Employee Compensation. We recognize ongoing share-based payments to employees, including grants of employee stock options and stock appreciation rights (“SARs”), in the Consolidated Financial Statements as compensation cost over the service period based on their fair value on the date of grant. This compensation cost is recognized over the service period on a straight-line basis, net of an assumed forfeiture rate, for awards that actually vest. We present this compensation cost consistent with the other compensation costs for the employee recipient in either Payroll and employee benefits or G&A. See Note 16 for further discussion of our share-based compensation plans.
Legal Costs	Legal Costs. Settlement costs are accrued when they are deemed probable and reasonably estimable. Anticipated legal fees related to self-insured workers' compensation, employment practices liability, general liability, automobile liability, product liability and property losses (collectively, "property and casualty losses") are accrued when deemed probable and reasonably estimable. Legal fees not related to self-insured property and casualty losses are recognized as incurred. See Note 20 for further discussion of our legal proceedings.
Impairment or Disposal of Property, Plant and Equipment	Impairment or Disposal of Property, Plant and Equipment. Property, plant and equipment (“PP&E”) is tested for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. The assets are not recoverable if their carrying value is less than the undiscounted cash flows we expect to generate from such assets. If the assets are not deemed to be recoverable, impairment is measured based on the excess of their carrying value over their fair value. For purposes of impairment testing for our restaurants, we have concluded that an individual restaurant is the lowest level of independent cash flows unless it is more likely than not that we will refranchise restaurants as a group. We review our long-lived assets of such individual restaurants (primarily PP&E and allocated intangible assets subject to amortization) semi-annually for impairment, or whenever events or changes in circumstances indicate that the carrying amount of a restaurant may not be recoverable. We use two consecutive years of operating losses as our primary indicator of potential impairment for our semi-annual impairment testing of these restaurant assets. We evaluate the recoverability of these restaurant assets by comparing the estimated undiscounted future cash flows, which are based on our entity-specific assumptions, to the carrying value of such assets. For restaurant assets that are not deemed to be recoverable, we write-down an impaired restaurant to its estimated fair value, which becomes its new cost basis. Fair value is an estimate of the price a franchisee would pay for the restaurant and its related assets and is determined by discounting the estimated future after-tax cash flows of the restaurant, which include a deduction for royalties we would receive under a franchise agreement with terms substantially at market. The after-tax cash flows incorporate reasonable assumptions we believe a franchisee would make such as sales growth and margin improvement. The discount rate used in the fair value calculation is our estimate of the required rate of return that a franchisee would expect to receive when purchasing a similar restaurant and the related long-lived assets. The discount rate incorporates rates of returns for historical refranchising market transactions and is commensurate with the risks and uncertainty inherent in the forecasted cash flows. In executing our refranchising initiatives, we most often offer groups of restaurants for sale. When we believe it is more likely than not a restaurant or groups of restaurants will be refranchised for a price less than their carrying value, but do not believe the restaurant(s) have met the criteria to be classified as held for sale, we review the restaurants for impairment. We evaluate the recoverability of these restaurant assets by comparing estimated sales proceeds plus holding period cash flows, if any, to the carrying value of the restaurant or group of restaurants. For restaurant assets that are not deemed to be recoverable, we recognize impairment for any excess of carrying value over the fair value of the restaurants, which is based on the expected net sales proceeds. To the extent ongoing agreements to be entered into with the franchisee simultaneous with the refranchising are expected to contain terms, such as royalty rates, not at prevailing market rates, we consider the off-market terms in our impairment evaluation. We recognize any such impairment charges in Refranchising (gain) loss. Refranchising (gain) loss includes the gains or losses from the sales of our restaurants to new and existing franchisees, including any impairment charges discussed above, and associated termination, relocation or retention costs associated with store-level employees of refranchised stores or employees of restaurant-support centers which we have closed due to refranchising. We recognize gains on restaurant refranchisings when the sale transaction closes and control of the restaurant operations have transferred to the franchisee. When we decide to close a restaurant, it is reviewed for impairment and depreciable lives are adjusted based on the expected disposal date. Other costs incurred when closing a restaurant such as costs of disposing of the assets as well as other facility-related expenses from previously closed stores are generally expensed as incurred. Additionally, at the date we cease using a property under an operating lease, we record a liability for the net present value of any remaining lease obligations, net of estimated sublease income, if any. Any costs recorded upon store closure as well as any subsequent adjustments to liabilities for remaining lease obligations as a result of lease termination or changes in estimates of sublease income are recorded in Closures and impairment (income) expenses. To the extent we sell assets, primarily land, associated with a closed store, any gain or loss upon that sale is also recorded in Closures and impairment (income) expenses. Considerable management judgment is necessary to estimate future cash flows, including cash flows from continuing use, terminal value, sublease income and refranchising proceeds. Accordingly, actual results could vary significantly from our estimates.
Guarantees	Guarantees. We recognize, at inception of a guarantee, a liability for the fair value of certain obligations undertaken. The majority of our guarantees are issued as a result of assigning our interest in obligations under operating leases as a condition to the refranchising of certain Company restaurants. We recognize a liability for the fair value of such lease guarantees upon refranchising and upon subsequent renewals of such leases when we remain contingently liable. The related expense and any subsequent changes are included in Refranchising (gain) loss. Any expense and subsequent changes in the guarantees for other franchise support guarantees not associated with a refranchising transaction are included in Franchise and license expense.
Income Taxes	Income Taxes. We record deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases as well as operating loss, capital loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those differences or carryforwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in our Income tax provision in the period that includes the enactment date. Additionally, in determining the need for recording a valuation allowance against the carrying amount of deferred tax assets, we consider the amount of taxable income and periods over which it must be earned, actual levels of past taxable income and known trends and events or transactions that are expected to affect future levels of taxable income. Where we determine that it is more likely than not that all or a portion of an asset will not be realized, we record a valuation allowance. We recognize the benefit of positions taken or expected to be taken in our tax returns in our income tax provision when it is more likely than not (i.e. a likelihood of more than fifty percent) that the position would be sustained upon examination by tax authorities. A recognized tax position is then measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon settlement. We evaluate these amounts on a quarterly basis to ensure that they have been appropriately adjusted for audit settlements and other events we believe may impact the outcome. Changes in judgment that result in subsequent recognition, derecognition or a change in measurement of a tax position taken in a prior annual period (including any related interest and penalties) are recognized as a discrete item in the interim period in which the change occurs. We recognize accrued interest and penalties related to unrecognized tax benefits as components of our income tax provision. We do not record a deferred tax liability for unremitted earnings of our foreign subsidiaries (except for the U.S. tax provided for as part of the Tax Act enacted on December 22, 2017, see Note 18) to the extent that the earnings meet the indefinite reversal criteria. This criteria is met if the foreign subsidiary has invested, or will invest, the earnings indefinitely. The decision as to the amount of unremitted earnings that we intend to maintain in non-U.S. subsidiaries considers items including, but not limited to, forecasts and budgets of financial needs of cash for working capital, liquidity plans and expected cash requirements in the U.S. See Note 18 for a further discussion of our income taxes.
Fair Value Measurements	Fair Value Measurements. Fair value is the price we would receive to sell an asset or pay to transfer a liability (exit price) in an orderly transaction between market participants. For those assets and liabilities we record or disclose at fair value, we determine fair value based upon the quoted market price, if available. If a quoted market price is not available for identical assets, we determine fair value based upon the quoted market price of similar assets or the present value of expected future cash flows considering the risks involved, including counterparty performance risk if appropriate, and using discount rates appropriate for the duration. The fair values are assigned a level within the fair value hierarchy, depending on the source of the inputs into the calculation. Level 1 Inputs based upon quoted prices in active markets for identical assets. Level 2 Inputs other than quoted prices included within Level 1 that are observable for the asset, either directly or indirectly. Level 3 Inputs that are unobservable for the asset.
Cash and Cash Equivalents	Cash and Cash Equivalents. Cash equivalents represent funds we have temporarily invested (with original maturities not exceeding three months), including short-term, highly liquid debt securities.
Receivables	Receivables. The Company’s receivables are primarily generated from ongoing business relationships with our franchisees as a result of franchise and lease agreements. Trade receivables consisting of royalties from franchisees, including Yum China, are generally due within 30 days of the period in which the corresponding sales occur and are classified as Accounts and notes receivable, net on our Consolidated Balance Sheet. Yum China is our largest franchisee and we recorded franchise fee revenues of approximately $260 million from Yum China in 2017. Our provision for uncollectible franchisee receivable balances is based upon pre-defined aging criteria or upon the occurrence of other events that indicate that we may not collect the balance due. Additionally, we monitor the financial condition of our franchisees and record provisions for estimated losses on receivables when we believe it probable that our franchisees will be unable to make their required payments. While we use the best information available in making our determination, the ultimate recovery of recorded receivables is also dependent upon future economic events and other conditions that may be beyond our control. We recorded $5 million , less than $1 million and $6 million in net provisions within Franchise and license expenses in 2017 , 2016 and 2015 , respectively, related to uncollectible franchise and license trade receivables.Trade receivables that are ultimately deemed to be uncollectible, and for which collection efforts have been exhausted, are written off against the allowance for doubtful accounts. 2017 2016 Accounts and notes receivable $ 419 $ 384 Allowance for doubtful accounts (19 ) (14 ) Accounts and notes receivable, net $ 400 $ 370 Our financing receivables primarily consist of notes receivables and direct financing leases with franchisees which we enter into from time-to-time. As these receivables primarily relate to our ongoing business agreements with franchisees, we consider such receivables to have similar risk characteristics and evaluate them as one collective portfolio segment and class for determining the allowance for doubtful accounts. We monitor the financial condition of our franchisees and record provisions for estimated losses on receivables when we believe it is probable that our franchisees will be unable to make their required payments. Balances of notes receivable and direct financing leases due within one year are included in Accounts and notes receivable, net while amounts due beyond one year are included in Other assets. Amounts included in Other assets totaled $38 million and $29 million (net of an allowance of $2 million ) at December 31, 2017 and December 31, 2016
Inventories	Inventories. We value our inventories at the lower of cost (computed on the first-in, first-out method) or market.
Property, Plant and Equipment	Property, Plant and Equipment. We state PP&E at cost less accumulated depreciation and amortization. We calculate depreciation and amortization on a straight-line basis over the estimated useful lives of the assets as follows: 5 to 25 years for buildings and leasehold improvements, 3 to 20 years for machinery and equipment and 3 to 7
Leases and Leasehold Improvements	Leases and Leasehold Improvements. The Company leases land, buildings or both for certain of its restaurants and restaurant support centers worldwide. The length of our lease terms, which vary by country and often include renewal options, are an important factor in determining the appropriate accounting for leases including the initial classification of the lease as capital or operating and the timing of recognition of rent expense over the duration of the lease. We include renewal option periods in determining the term of our leases when failure to renew the lease would impose a penalty on the Company in such an amount that a renewal appears to be reasonably assured at the inception of the lease. The primary penalty to which we are subject is the economic detriment associated with the existence of leasehold improvements which might be impaired if we choose not to continue the use of the leased property. Leasehold improvements are amortized over the shorter of their estimated useful lives or the lease term. We generally do not receive leasehold improvement incentives upon opening a store that is subject to a lease. We expense rent associated with leased land or buildings while a restaurant is being constructed whether rent is paid or we are subject to a rent holiday. Additionally, certain of the Company's operating leases contain predetermined fixed escalations of the minimum rent during the lease term. For leases with fixed escalating payments and/or rent holidays, we record rent expense on a straight-line basis over the lease term, including any option periods considered in the determination of that lease term. Contingent rentals are based on sales levels in excess of stipulated amounts, and thus are not considered minimum lease payments and are included in rent expense when attainment of the contingency is considered probable (e.g. when Company sales occur).
Internal Development Costs and Abandoned Site Costs	Internal Development Costs and Abandoned Site Costs. We capitalize direct costs associated with the site acquisition and construction of a Company unit on that site, including direct internal payroll and payroll-related costs. Only those site-specific costs incurred subsequent to the time that the site acquisition is considered probable are capitalized. If we subsequently make a determination that it is probable a site for which internal development costs have been capitalized will not be acquired or developed, any previously capitalized internal development costs are expensed and included in G&A.
Goodwill and Intangible Assets	Goodwill and Intangible Assets. From time-to-time, the Company acquires restaurants from one of our Concept’s franchisees or acquires another business. Goodwill from these acquisitions represents the excess of the cost of a business acquired over the net of the amounts assigned to assets acquired, including identifiable intangible assets and liabilities assumed. Goodwill is not amortized and has been assigned to reporting units for purposes of impairment testing. Our reporting units are our business units (which are aligned based on geography) in our KFC, Pizza Hut and Taco Bell Divisions. We evaluate goodwill for impairment on an annual basis or more often if an event occurs or circumstances change that indicate impairment might exist. We have selected the beginning of our fourth quarter as the date on which to perform our ongoing annual impairment test for goodwill. We may elect to perform a qualitative assessment for our reporting units to determine whether it is more likely than not that the fair value of the reporting unit is greater than its carrying value. If a qualitative assessment is not performed, or if as a result of a qualitative assessment it is not more likely than not that the fair value of a reporting unit exceeds its carrying value, then the reporting unit’s fair value is compared to its carrying value. Fair value is the price a willing buyer would pay for a reporting unit, and is generally estimated using discounted expected future after-tax cash flows from Company-owned restaurant operations and franchise royalties. The discount rate is our estimate of the required rate of return that a third-party buyer would expect to receive when purchasing a business from us that constitutes a reporting unit. We believe the discount rate is commensurate with the risks and uncertainty inherent in the forecasted cash flows. If the carrying value of a reporting unit exceeds its fair value, goodwill is written down to its implied fair value. If we record goodwill upon acquisition of a restaurant(s) from a franchisee and such restaurant(s) is then sold within two years of acquisition, the goodwill associated with the acquired restaurant(s) is written off in its entirety. If the restaurant is refranchised two years or more subsequent to its acquisition, we include goodwill in the carrying amount of the restaurants disposed of based on the relative fair values of the portion of the reporting unit disposed of in the refranchising and the portion of the reporting unit that will be retained. The fair value of the portion of the reporting unit disposed of in a refranchising is determined by reference to the discounted value of the future cash flows expected to be generated by the restaurant and retained by the franchisee, which includes a deduction for the anticipated, future royalties the franchisee will pay us associated with the franchise agreement entered into simultaneously with the refranchising transition. The fair value of the reporting unit retained is based on the price a willing buyer would pay for the reporting unit and includes the value of franchise agreements. Appropriate adjustments are made if a franchise agreement includes terms that are determined to not be at prevailing market rates. As such, the fair value of the reporting unit retained can include expected cash flows from future royalties from those restaurants currently being refranchised, future royalties from existing franchise businesses and company restaurant operations. As a result, the percentage of a reporting unit’s goodwill that will be written off in a refranchising transaction will be less than the percentage of the reporting unit’s Company-owned restaurants that are refranchised in that transaction and goodwill can be allocated to a reporting unit with only franchise restaurants.
Derivative Financial Instruments	Derivative Financial Instruments. We use derivative instruments primarily to hedge interest rate and foreign currency risks. These derivative contracts are entered into with financial institutions. We do not use derivative instruments for trading purposes and we have procedures in place to monitor and control their use. We record all derivative instruments on our Consolidated Balance Sheet at fair value. For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative instrument is reported as a component of AOCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Any ineffective portion of the gain or loss on the derivative instrument for a cash flow hedge is recorded in the results of operations immediately. For derivative instruments not designated as hedging instruments, the gain or loss is recognized in the results of operations immediately.
Common Stock Share Repurchases	Common Stock Share Repurchases. From time-to-time, we repurchase shares of our Common Stock under share repurchase programs authorized by our Board of Directors. Shares repurchased constitute authorized, but unissued shares under the North Carolina laws under which we are incorporated. Additionally, our Common Stock has no par or stated value. Accordingly, we record the full value of share repurchases, or other deductions to Common Stock such as shares cancelled upon employee share-based award exercises, upon the trade date, against Common Stock on our Consolidated Balance Sheet except when to do so would result in a negative balance in such Common Stock account. In such instances, on a period basis, we record the cost of any further share repurchases, or other deductions to Common Stock such as shares cancelled upon employee share-based award exercises, as an addition to Accumulated deficit. Due to the large number of share repurchases of our stock over the past several years, our Common Stock balance is frequently zero at the end of any period. Accordingly, $1,915 million , $5,399 million and $1,124 million in share repurchases in 2017 , 2016 and 2015 , respectively, and $20 million
Pension and Post-retirement Medical Benefits	Pension and Post-retirement Medical Benefits. We measure and recognize the overfunded or underfunded status of our pension and post-retirement plans as an asset or liability in our Consolidated Balance Sheet as of our fiscal year end. The funded status represents the difference between the projected benefit obligations and the fair value of plan assets, which is calculated on a plan-by-plan basis. The projected benefit obligation and related funded status are determined using assumptions as of the end of each year. The projected benefit obligation is the present value of benefits earned to date by plan participants, including the effect of future salary increases, as applicable. The difference between the projected benefit obligations and the fair value of plan assets that has not previously been recognized in our Consolidated Statement of Income is recorded as a component of AOCI. The net periodic benefit costs associated with the Company's defined benefit pension and post-retirement medical plans are determined using assumptions regarding the projected benefit obligation and, for funded plans, the market-related value of plan assets as of the beginning of each year, or remeasurement period, it applicable. We record the service cost component of net periodic benefit costs in G&A. Non-service cost components are recorded in Other pension (income) expense. We have elected to use a market-related value of plan assets to calculate the expected return on assets, net of administrative and investment fees paid from plan assets, in net periodic benefit costs. We recognize differences in the fair value versus the market-related value of plan assets evenly over five years. For each individual plan we amortize into pension expense the net amounts in AOCI, as adjusted for the difference between the fair value and market-related value of plan assets, to the extent that such amounts exceed 10% of the greater of a plan’s projected benefit obligation or market-related value of assets, over the remaining service period of active participants in the plan or, for plans with no active participants, over the expected average life expectancy of the inactive participants in the plan. We record a curtailment when an event occurs that significantly reduces the expected years of future service or eliminates the accrual of defined benefits for the future services of a significant number of employees. We record a curtailment gain when the employees who are entitled to the benefits terminate their employment; we record a curtailment loss when it becomes probable a loss will occur.

Refranchising (gain) loss [Member]
Facility Actions [Line Items]
Facility Actions	Refranchising (Gain) Loss The Refranchising (gain) loss by reportable segment is presented below. Given the size and volatility of refranchising initiatives, our chief operating decision maker ("CODM") does not consider the impact of Refranchising (gain) loss when assessing segment performance. As such, we do not allocate such gains and losses to our segments for performance reporting purposes. During the years ended December 31, 2017, 2016 and 2015, we refranchised 1,470 , 432 and 270 restaurants, respectively. We received $1,773 million , $370 million and $213 million in pre-tax proceeds in 2017, 2016 and 2015, respectively, related to these transactions. A summary of Refranchising (gain) loss is as follows: Refranchising (gain) loss 2017 2016 2015 KFC Division (a) $ (581 ) $ (44 ) $ 32 Pizza Hut Division (a) (16 ) (48 ) 56 Taco Bell Division (486 ) (71 ) (65 ) Worldwide $ (1,083 ) $ (163 ) $ 23 (a) In 2010, we refranchised our then-remaining Company-operated restaurants in Mexico. To the extent we owned it, we did not sell the real estate related to certain of these restaurants, instead leasing it to the franchisee. During 2015, we sold the real estate for approximately $58 million . While these proceeds exceeded the book value of the real estate, the sale represented a substantial liquidation of our Mexican foreign entities under GAAP. As such, the accumulated translation losses associated with our Mexican business were included in our loss on the sale. We recorded charges of $80 million representing the excess of the sum of the book value of the real estate and other related assets and our accumulated translation losses over the sales price. Consistent with the classification of the original Mexico market-wide refranchising transaction, these charges were classified as Refranchising (gain) loss. Refranchising losses of $40 million were associated with both the KFC and Pizza Hut Divisions. We continue to earn U.S. dollar-denominated franchise fees, most of which are sales-based royalties, under our existing franchise contracts with our Mexico franchisee. As a result of classifying restaurant and related assets as held-for-sale and ceasing depreciation expense as well as recording any related write-downs to fair value, depreciation expense was reduced versus what would have otherwise been recorded by $10 million during the year ended December 31, 2017. Our CODM does not consider the impact of these depreciation reductions, which were recorded within Occupancy and other operating expenses when assessing segment performance. These depreciation reductions were not allocated to the Division segments resulting in depreciation expense continuing to be recorded within our Divisional results at the rate at which it was prior to the held-for-sale classification.

[2]	In 2010, we refranchised our then-remaining Company-operated restaurants in Mexico. To the extent we owned it, we did not sell the real estate related to certain of these restaurants, instead leasing it to the franchisee. During 2015, we sold the real estate for approximately $58 million . While these proceeds exceeded the book value of the real estate, the sale represented a substantial liquidation of our Mexican foreign entities under GAAP. As such, the accumulated translation losses associated with our Mexican business were included in our loss on the sale. We recorded charges of $80 million representing the excess of the sum of the book value of the real estate and other related assets and our accumulated translation losses over the sales price. Consistent with the classification of the original Mexico market-wide refranchising transaction, these charges were classified as Refranchising (gain) loss. Refranchising losses of $40 million

Operating Profit	[14]																			$ 1,650		$ 1,394

[1]	Store closure (income) costs include the net gain or loss on sales of real estate on which we formerly operated a Company-owned restaurant that was closed, lease reserves established when we cease using a property under an operating lease and subsequent adjustments to those reserves and other facility-related expenses from previously closed stores. Remaining lease obligations for closed stores were not material at December 31, 2017 or December 31, 2016.
[2]	In 2010, we refranchised our then-remaining Company-operated restaurants in Mexico. To the extent we owned it, we did not sell the real estate related to certain of these restaurants, instead leasing it to the franchisee. During 2015, we sold the real estate for approximately $58 million . While these proceeds exceeded the book value of the real estate, the sale represented a substantial liquidation of our Mexican foreign entities under GAAP. As such, the accumulated translation losses associated with our Mexican business were included in our loss on the sale. We recorded charges of $80 million representing the excess of the sum of the book value of the real estate and other related assets and our accumulated translation losses over the sales price. Consistent with the classification of the original Mexico market-wide refranchising transaction, these charges were classified as Refranchising (gain) loss. Refranchising losses of $40 million
[3]	For discussion of the settlement payments made in connection with the deferred vested program in 2016, see Note 5.
[4]	Settlement losses result when benefit payments exceed the sum of the service cost and interest cost within a plan during the year. These losses were recorded in Other pension (income) expense.

[7]	Includes net gains from refranchising initiatives of $54 million , $21 million and $88 million in the second, third and fourth quarters, respectively, costs associated with YUM’s Strategic Transformation Initiatives of $4 million , $30 million and $33 million in the second, third and fourth quarters, respectively, a non-cash charge primarily associated with the modification of share-based compensation awards in connection with the Separation of $30 million in the fourth quarter and costs associated with KFC U.S. Acceleration Agreement of $9 million , $8 million and $9 million in the first, second and fourth quarters, respectively. See Note 5.

[11]	Includes Yum China financial results from January 1, 2016 to October 31, 2016.

[1]	Restaurant-level impairment charges are recorded in Closures and impairment (income) expenses and resulted primarily from our semi-annual impairment evaluation of long-lived assets of individual restaurants that were being operated at the time of impairment and had not been offered for refranchising. The fair value measurements used in these impairment evaluations were based on discounted cash flow estimates using unobservable inputs (Level 3).
[2]	During 2016, we made the decision to dispose of a corporate aircraft. The loss associated with this then planned sale reflected the shortfall of the expected proceeds, less any selling costs, over the carrying value of the aircraft. The expected proceeds were based on actual bids received from potential buyers for similar assets (Level 2).
[3]	We estimated the fair value of the YUM and Subsidiary Senior Unsecured Notes, Term Loan A Facility, and Term Loan B Facility using market quotes and calculations based on market rates.
[4]	We estimated the fair value of the Securitization Notes by obtaining broker quotes from two separate brokerage firms that are knowledgeable about the Company’s Securitization Notes and, at times, trade these notes. The markets in which the Securitization Notes trade are not considered active markets.
