New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards Intangibles In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which removes the requirement to compare the implied fair value of goodwill with its carrying amount as part of step 2 of the goodwill impairment test. As a result, an impairment charge will be recorded based on the excess of a reporting unit's carrying amount over its fair value. ASU 2017-04 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The Company does not expect an impact to the consolidated financial statements from the adoption of ASU 2017-04. Income Taxes In October 2016, the FASB issued ASU 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.” The goal of this update is to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. ASU 2016-16 is effective for fiscal years beginning after December 15, 2017, including interim periods within those annual reporting periods. The Company anticipates ASU 2016-16 will have a material impact on the consolidated balance sheet, primarily resulting in additional deferred tax assets and a related reduction in prepaid assets, but little to no impact on the consolidated statements of income and cash flows. Lease Accounting In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The Company anticipates ASU 2016-02 will have a material impact on the consolidated balance sheet. The impact of ASU 2016-02 is non-cash in nature, as such, it will not affect the Company’s cash flows. The Company is currently evaluating the impact of ASU 2016-02 on the consolidated statement of income. Revenue Recognition In May 2014, the FASB issued guidance codified in Accounting Standards Codification ("ASC") 606, "Revenue Recognition - Revenue from Contracts with Customers," which amends the guidance in former ASC 605, "Revenue Recognition." The core principle of the standard is to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration expected to be received for those goods or services. The standard also calls for additional disclosures around the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company will adopt the standard effective January 1, 2018. The standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption ("modified retrospective method"). The Company currently expects to apply the modified retrospective method upon adoption. The Company does not believe the standard will impact its recognition of revenue from Company-operated restaurants or its recognition of royalties from restaurants operated by franchisees or licensed to affiliates and developmental licensees, which are based on a percent of sales. While we continue to assess the potential impacts to other less significant revenue transactions, we currently expect the standard will change the way initial fees from franchisees for new restaurant openings or new franchise terms are recognized. The Company's current accounting policy is to recognize initial franchise fees when a new restaurant opens or at the start of a new franchise term. In accordance with the new guidance, the initial franchise services are not distinct from the continuing rights or services offered during the term of the franchise agreement, and will therefore be treated as a single performance obligation. As such, initial fees received will likely be recognized over the franchise term. Although the standard will impact the manner in which we record revenue from initial fees, we do not anticipate this impact to be material to the Company’s consolidated statement of income. The cumulative catch-up adjustment to be recorded as deferred revenue upon adoption is expected to be approximately 2% of the Company's consolidated long-term liabilities. No impact to the Company's consolidated statement of cash flows is expected as the initial fees will continue to be collected upon the restaurant opening date or the beginning of a new franchise term.
