Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation Throughout this report, the terms “our,” “we,” “us,” and the “Company” refers to FleetCor Technologies, Inc. and its subsidiaries. The Company prepared the accompanying interim consolidated financial statements in accordance with Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States (“GAAP”). The unaudited consolidated financial statements reflect all adjustments considered necessary for fair presentation. These adjustments consist primarily of normal recurring accruals and estimates that impact the carrying value of assets and liabilities. Actual results may differ from these estimates. Operating results for the three and six month periods ended June 30, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016. The unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. Foreign Currency Translation Assets and liabilities of foreign subsidiaries are translated into U.S. dollars at the rates of exchange in effect at period-end. The related translation adjustments are made directly to accumulated other comprehensive income. Income and expenses are translated at the average monthly rates of exchange in effect during the period. Gains and losses from foreign currency transactions of these subsidiaries are included in net income. The Company recognized foreign exchange losses of $0.2 million and $0.7 million for the three months ended June 30, 2016 and 2015, respectively. The Company recognized foreign exchange losses of $0.8 million and $2.6 million for the six months ended June 30, 2016 and 2015, respectively, which are recorded within other expense, net in the Unaudited Consolidated Statements of Income. Revision of Previously Issued Financial Statements As discussed in footnote 2 to the Company's 2015 consolidated financial statements, the Company corrected a misstatement and other comprehensive income to properly reflect the translation of certain acquired intangibles. Other comprehensive income for the three and six months ended June 30, 2015 has been revised from our previously reported gain of $6.8 million and loss of $86.2 million, respectively, to be consistent with the presentation in the December 31, 2015 financial statements. The Company does not believe this revision is material to any prior period financial statements. Adoption of New Accounting Standards Going Concern In August 2013, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2014-15 “Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern”, which requires entities to perform interim and annual assessments of the entity’s ability to continue as a going concern within one year of the date of issuance of the entity’s financial statements. This ASU is effective for fiscal years ending after December 15, 2016 and interim periods thereafter, with early adoption permitted. The Company’s adoption of this ASU is not expected to have a material impact on the results of operations, financial condition, or cash flows, as it is disclosure based. Revenue Recognition In May 2014, the FASB issued Accounting Standards Codification ("ASC") 606, “Revenue from Contracts with Customers”, which amends the guidance in former ASC 605, Revenue Recognition. This amended guidance requires revenue to be recognized in an amount that reflects the consideration to which the company expects to be entitled for those goods and services when the performance obligation has been satisfied. This amended guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and related cash flows arising from contracts with customers. In August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers: Deferral of the Effective Date”, which defers the effective date of the new revenue recognition standard by one year. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net)”, which clarifies how an entity should identify the unit of accounting for the principal versus agent evaluation and how it should apply the control principle to certain types of arrangements. In April 2016, the FASB issued ASU 2016-10, "Identifying Performance Obligations and Licensing", which clarifies the accounting for intellectual property licenses and identifying performance obligations. In May 2016, the FASB issued ASU 2016-11, "Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting", which rescinds certain SEC guidance in response to announcements made by the SEC staff at the EITF's March 3, 2016 meeting and ASU 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients", which clarifies the guidance on collectibility, non-cash consideration, the presentation of sales and other similar taxes collected from customers and contract modifications and completed contracts at transition. Additionally, ASU 2016-12 clarifies that entities electing the full retrospective transition method would no longer be required to disclose the effect of the change in accounting principle on the period of adoption; however, entities would still be required to disclose the effects on preadoption periods that were retrospectively adjusted. These ASUs are effective for the Company for reporting periods beginning after December 15, 2017, but permit companies the option to adopt as of the original effective date. The Company is currently evaluating the impact of the provisions of ASC 606. The guidance permits the use of either a retrospective or cumulative effect transition method. The Company anticipates selecting the modified retrospective method during transition and is currently evaluating the impact of the provisions of ASC 605 on the results of operations, financial condition, and cash flows. Simplification of Guidance on Debt Issuance Costs In April 2015, the FASB issued ASU 2015-3, “Interest—Imputation of Interest”, which changes the presentation of debt issuance costs in financial statements as a direct deduction from the related debt liability rather than as an asset. This ASU is effective for us for fiscal years ending after December 15, 2015 and interim periods. Early adoption is permitted. In August 2015, the FASB issued ASU 2015-15, “Interest-Imputation of Interest: Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements”, which is effective immediately. The SEC staff clarified that entities may continue presenting unamortized debt issuance costs for line-of-credit arrangements as an asset. The Company adopted this new guidance on January 1, 2016. As a result of the adoption of this ASU, $0.6 million and $1.5 million of unamortized debt issuance costs were retrospectively adjusted from prepaid expenses and other current assets to the current portion of notes payable and lines of credit and other assets to notes payable and other obligations, less current portion, respectively, in the Company’s Consolidated Balance Sheet as of December 31, 2015. Simplification of Balance Sheet Classification of Deferred Taxes In November 2015, the FASB issued ASU 2015-17, “Balance Sheet Classification of Deferred Taxes”, which requires entities to present deferred tax assets (DTAs) and deferred tax liabilities (DTLs) as noncurrent in a classified balance sheet. It thus simplifies the current guidance, which requires entities to separately present DTAs and DTLs as current or noncurrent in a classified balance sheet. Netting of DTAs and DTLs by tax jurisdiction is still required under the new guidance. This ASU is effective for the Company for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. The Company’s adoption of this ASU is not expected to have a material impact on the results of operations, financial condition, or cash flows. Accounting for Leases In February 2016, the FASB issued ASU 2016-02, “Leases”, which requires lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with the exception of short-term leases. This ASU also requires disclosures to provide additional information about the amounts recorded in the financial statements. This ASU is effective for the Company for annual periods beginning after December 15, 2018 and interim periods therein. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition and requires application of the new guidance for leases that exist or are entered into after the beginning of the earliest comparative period presented. The Company is currently evaluating the impact of this ASU on the results of operations, financial condition, or cash flows. Accounting for Breakage In March 2016, the FASB issued ASU 2016-04, “Liabilities-Extinguishments of Liabilities: Recognition of Breakage for Certain Prepaid Stored-Value Products”, which requires entities that sell prepaid stored value products redeemable for goods, services or cash at third-party merchants to derecognize liabilities related to those products for breakage. This ASU is effective for the Company for reporting periods beginning after December 15, 2017. Early adoption is permitted. The ASU must be adopted using either a modified retrospective approach with a cumulative effect adjustment to retained earnings as of the beginning of the period of adoption or a full retrospective approach. The Company’s adoption of this ASU is not expected to have a material impact on the results of operations, financial condition, or cash flows. Accounting for Employee Share-Based Payment In March 2016, the FASB issued ASU 2016-09, “Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting”, which requires entities to record all tax effects of share-based awards to employees in the income statement when the awards vest or are settled. The ASU also allows an employer to repurchase more of an employee’s shares than currently allowed for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. This ASU is effective for the Company for reporting periods beginning after December15, 2016. Early adoption is permitted, but all of the guidance must be adopted in the same period. The Company expects to early adopt this ASU in the third quarter of 2016, reflecting any adjustments as of January 1, 2016. The adoption of this ASU will result in excess tax benefits being recorded as a reduction of income tax expense and an increase in the number of dilutive shares outstanding at the end of each period, which may result in an increase to diluted earnings per share, depending on the volume of share-based payment award activity during the respective period.
