Accounting Policies [Abstract]
Basis of Accounting	The accompanying unaudited consolidated financial statements of Choice Hotels International, Inc. and subsidiaries (together the "Company") have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). These unaudited consolidated financial statements include all adjustments that are necessary, in the opinion of management, to fairly present the Company's financial position and results of operations. Except as otherwise disclosed, all adjustments are of a normal recurring nature. Certain information and footnote disclosures normally included in financial statements presented in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been omitted. The Company believes the disclosures made are adequate to make the information presented not misleading. The consolidated financial statements should be read in conjunction with the consolidated financial statements for the year ended December 31, 2016 and notes thereto included in the Company’s Annual Report on Form 10-K, filed with the SEC on February 27, 2017 (the "10-K"). Interim results are not necessarily indicative of the entire year results. All inter-company transactions and balances between Choice Hotels International, Inc. and its subsidiaries have been eliminated in consolidation. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures 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 those estimates.
Recently Adopted Accounting Guidance and Future Adoption of Recently Announced Accounting Guidance	Recently Adopted Accounting Guidance In October 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-17, Consolidation (Topic 810) - Interests Held through Related Parties That Are under Common Control ("ASU No. 2016-17"). ASU No. 2016-17 alters the primary beneficiary assessment a reporting entity must perform as part of consolidation analysis to determine whether it should consolidate certain types of legal entities. Under legacy GAAP, indirect interests held through related parties under common control were to be considered in their entirety by the reporting entity in performing the primary beneficiary assessment. ASU No. 2016-17 revises the guidance such that indirect interests held through related parties under common control are considered on a proportionate basis in performing the primary beneficiary assessment. The Company adopted this ASU on January 1, 2017, and it did not have an impact on the Company's consolidated financial statements. Future Adoption of Recently Announced Accounting Guidance In May 2014, the FASB issued ASU No. 2014-09, Revenue From Contracts with Customers (Topic 606) ("ASU No. 2014-09") and issued subsequent amendments to the initial guidance at various points of 2015 and 2016 within ASU No. 2015-14, ASU No. 2016-08, ASU No. 2016-10, ASU No. 2016-12, and ASU No. 2016-20 (these ASUs collectively referred to as "Topic 606"). Topic 606 impacts virtually all aspects of an entity's revenue recognition and supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, as well as most industry-specific guidance. Topic 606 significantly enhances comparability of revenue recognition practices across entities and industries by providing a principles-based, comprehensive framework for addressing revenue recognition issues. In order for a provider of promised goods or services to recognize as revenue the consideration that it expects to receive in exchange for the promised goods or services, the provider should apply the following five steps: (1) identify the contract with a customer(s); (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. Topic 606 also specifies the accounting for some costs to obtain or fulfill a contract with a customer and provides enhanced disclosure requirements. Topic 606 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The guidance permits the retrospective or modified retrospective method when adopting Topic 606. The Company intends to adopt the standard in the annual period beginning January 1, 2018, and has not yet determined the method of adoption. The Company's evaluation is still preliminary for all areas below. The Company has determined royalties earned in exchange for a license to brand intellectual property on franchise agreements will be recognized in revenue over time typically after the occurrence of a completed stay, which is consistent with current practice. We are continuing to evaluate the services we provide as part of the franchise agreement, including the Choice Privileges loyalty program and other programs we operate as part of the marketing and reservation system. The Company has determined initial and relicensing fees earned upon execution of a franchise agreement will be recognized as revenue ratably as services are provided over the enforceable period of the franchise license arrangement. This represents a change from current practice, whereby the Company typically will recognize revenue for initial and relicensing fees in full in the period of agreement execution. Similarly, the Company has determined sales commissions paid upon the execution of a franchise agreement will be recognized as expense ratably over the same period as revenues are recognized. This also represents a change, as the Company’s current practice is typically to recognize expense for sales commissions in full in the period of agreement execution. The Company is in the process of finalizing the periods of recognition and calculating the expected impacts for this revision. Additionally, the Company will no longer defer revenue or expenses or record assets and liabilities when system fee revenues exceed expenses in the current period or vice versa. As a result, the Company anticipates net income or loss may be generated, which will represent a change from current practice. The Company believes the timing of recognition for profits from the sale of real estate assets will be accelerated under Topic 606, resulting from the removal of real estate specific guidance. The Company is in the process of calculating the expected impact of this revision. We continue to evaluate the accounting for other Company revenue streams for impacts as a result of adopting the standard. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU No. 2016-02"). ASU No. 2016-02 requires lessees to recognize most leases on their balance sheet by recording a liability for its lease obligation and an asset for its right to use the underlying asset as of the lease commencement date. The standard requires entities to determine whether an arrangement contains a lease or a service agreement as the accounting treatment is significantly different between the two arrangements. The standard also requires the lessee to evaluate whether a lease is a financing lease or an operating lease as the accounting and presentation guidance between the two are different. ASU No. 2016-02 also modifies the classification criteria and accounting for sales-type and direct financing leases for lessors. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the potential impact that ASU No. 2016-02 will have on the financial statements and disclosures. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) ("ASU No. 2016-13"), which will require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The guidance is effective for annual reporting periods beginning after December 15, 2019 and interim periods within those fiscal years. The Company is currently assessing the potential impact that ASU No. 2016-13 will have on its consolidated financial position or results of operations. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments ("ASU No. 2016-15"). ASU No. 2016-15 provides additional guidance on eight specific cash flow issues, such as the classification of debt prepayments or extinguishment costs, contingent consideration payments made after a business combination, and distributions received from equity method investees. The guidance is effective for annual reporting periods beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the potential impact that ASU No. 2016-15 will have on the financial statements and disclosures. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740) - Intra-Entity Transfers of Assets Other Than Inventory ("ASU No. 2016-16"). ASU No. 2016-16 provides guidance on recognition of current income tax consequences for intercompany asset transfers (other than inventory) at the time of transfer. This represents a change from current GAAP, where the consolidated tax consequences of intercompany asset transfers are deferred from the time of transfer to a future period. The guidance is effective for annual reporting periods beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption at the beginning of an annual period is permitted. The Company is currently assessing the potential impact that ASU No. 2016-16 will have on the financial statements and disclosures. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230) Restricted Cash ("ASU 2016-18"). ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The guidance is effective for public business entities for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The Company is currently assessing the potential impact that ASU No. 2016-18 will have on the financial statements and disclosures. In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment ("ASU No. 2017-04"). ASU 2017-04 eliminates the two-step process that required identification of potential impairment and a separate measure of the actual impairment. The annual assessment of goodwill impairment will be determined by using the difference between the carrying amount and the fair value of the reporting unit. The guidance is effective for public business entities for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The Company is currently assessing the potential impact that ASU No. 2017-04 will have on the financial statements and disclosures. In February 2017, the FASB issued ASU No. 2017-05, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets ("ASU No. 2017-05"). This ASU clarifies the scope and accounting of a financial asset that meets the definition of an “in-substance nonfinancial asset” and defines the term “in-substance nonfinancial asset.” This ASU also adds guidance for partial sales of nonfinancial assets. ASU 2017-05 will be effective for fiscal years beginning after December 15, 2017, including interim reporting periods within that reporting period. The Company is assessing the potential impact that ASU 2017-05 will have on the financial statements and disclosures. In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation: Scope of Modification Accounting, which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award changes as a result of the change in terms or conditions. ASU 2017-09 will be applied prospectively to awards modified on or after the adoption date. The standard is effective for the Company’s financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of this ASU will have on the financial statements and disclosures.
