Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The Company’s fiscal quarters end on the Sunday closest to the last day of each calendar quarter. For convenience, the fiscal quarters of each year are referred to as ending on March 31, June 30, September 30 and December 31. The first fiscal quarter of 2020 began on December 30, 2019 and ended on March 29, 2020; the second and third fiscal quarters of 2020 ended on June 28, 2020 and September 27, 2020, respectively. The first fiscal quarter of 2019 began on December 31, 2018 and ended on March 31, 2019; the second and third fiscal quarters of 2019 ended on June 30, 2019 and September 29, 2019, respectively. The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries that are consolidated in accordance with U.S. GAAP. All intercompany balances and transactions have been eliminated. The preparation of financial statements in conformity with U.S. GAAP requires the Company’s management to make assumptions and estimates that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities, if any, at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates are made in the calculation and assessment of the following: impairment of goodwill, other intangible assets and tangible assets; income taxes; allowance for doubtful accounts and notes receivables; lease accounting estimates; contingencies; and stock-based compensation. On an ongoing basis, the Company evaluates its estimates based on historical experience, current conditions and various other assumptions that are believed to be reasonable under the circumstances. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Actual results could differ from those estimates. Risks and Uncertainties The Company was subject to risks and uncertainties as a result of the rapidly spreading outbreak of a novel strain of coronavirus, designated “COVID-19.” The extent of the continued impact of the COVID-19 pandemic on the Company's business is highly uncertain and difficult to predict, as measures taken in response to and the effect of the pandemic has varied and continues to vary by state and municipalities within states. Assessments of the success of measures taken and the timing of any further restrictions, or lifting of such restrictions, is rapidly evolving. The Company first began to experience impacts from COVID-19 in March 2020, as federal, state and local governments began to react to the public health crisis by encouraging “social distancing” and requiring, in varying degrees, restaurant dine-in limitations and other restrictions that largely limited the restaurants of the Company's franchisees and its company-operated restaurants to take-out and delivery sales. Many international restaurants were temporarily closed for at least a part of March as well as a result of government restrictions put in place in various countries. Subsequent to imposition, government-imposed dine-in restrictions were relaxed in many of the locations in which the Company operates, although dining room capacity continues to be limited to 50% or less at most restaurants. Additionally, economies worldwide also have been negatively impacted by the COVID-19 pandemic, which possibly could cause a domestic and/or global economic recession. The Company has taken several actions to mitigate the effects of the COVID-19 pandemic on its operations and its franchisees, as follows: (i) drew down $220 million from its revolving credit facility, leaving available remaining borrowing under the facility of approximately $2 million; (ii) terminated repurchases of common stock for the foreseeable future; (iii) the Company's Board of Directors decided not to declare a dividend for the second, third and fourth quarters of 2020; (iv) voluntarily increased the interest reserve for securitized debt from the required $16.4 million (one quarter of estimated interest) to $32.8 million; (v) reduced discretionary costs, limited new hiring and reduced the use of independent contractors; (vi) temporarily furloughed certain team members across various functional groups at its restaurant support centers; (vii) deferred franchisee payment of royalty, advertising and other fees, and lease obligations for up to two months on a case-by-case basis; (viii) deferred franchisee remodel and development obligations for up to 15 months; (ix) engaged a national real estate firm to assist franchisees with landlord discussions regarding rent deferrals, abatements and other modifications to lease agreements; (x) negotiated deferrals and abatements for properties on which the Company was lessee and (xi) hired external consultants to work with franchisees in assessing their financial health and to better understand performance variability. The severity of the continued impact of the COVID-19 pandemic on the Company's business will depend on a number of factors, including, but not limited to, how long the pandemic will last, whether/when recurrences of the virus may arise, what restrictions on in-restaurant dining may be enacted or re-enacted, the timing and extent of customer re-engagement with the Company's brands and, in general, what the short- and long-term impact on consumer discretionary spending the COVID-19 pandemic might have on the Company and the restaurant industry as a whole, all of which are uncertain and cannot be predicted. The Company's future results of operations and liquidity could adversely be impacted by the length of time dine-in restrictions are in place and the success of any initiatives or programs that the Company may undertake to address financial and operational challenges faced by itself and its franchisees. As such, the extent to which the COVID-19 pandemic may continue to materially impact the Company's financial condition, liquidity, or results of operations is highly uncertain. Reclassifications Certain 2019 amounts previously reported have been reclassified to conform to the presentation requirements of a newly adopted accounting standard on the measurement of current expected credit losses (See Note 3). Amounts reported in 2019 have not been restated.
