Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the ordinary course of business, the Company is involved in various pending or threatened legal actions, arbitration proceedings, claims, subpoenas, and matters relating to compliance with laws and regulations (collectively, legal proceedings). Based on our current knowledge, management presently does not believe that the liabilities arising from these legal proceedings will have a material adverse effect on our consolidated financial condition, results of operations or cash flows. However, it is possible that the ultimate resolution of these legal proceedings could have a material adverse effect on our results of operations and financial condition for any particular period. Shareholder Class Action and Derivative Lawsuits On June 14, 2017, a shareholder filed a class action complaint in the United States District Court for the Northern District of Georgia against the Company and certain of its officers and directors on behalf of all persons who purchased or otherwise acquired the Company’s stock between February 5, 2016 and May 2, 2017. On October 13, 2017, the shareholder filed an amended complaint asserting claims on behalf of a putative class of all persons who purchased or otherwise acquired the Company's common stock between February 4, 2016 and May 3, 2017. The complaint alleges that the defendants made false or misleading statements regarding fee charges and the reasons for its earnings and growth in certain press releases and other public statements in violation of the federal securities laws. Plaintiff seeks class certification, unspecified monetary damages, costs, and attorneys’ fees. The Company disputes the allegations in the complaint and intends to vigorously defend against the claims. On July 10, 2017, a shareholder derivative complaint was filed against the Company and certain of the Company’s directors and officers in the United States District Court for the Northern District of Georgia seeking recovery on behalf of the Company. The derivative complaint alleges that the defendants issued a false and misleading proxy statement in violation of the federal securities laws; that defendants breached their fiduciary duties by causing or permitting the Company to make allegedly false and misleading public statements concerning the Company’s fee charges, and financial and business prospects; and that certain defendants breached their fiduciary duties through allegedly improper sales of stock. The complaint seeks unspecified monetary damages on behalf of the Company, corporate governance reforms, disgorgement of profits, benefits and compensation by the defendants, restitution, costs, and attorneys’ and experts’ fees. On September 20, 2018, the court entered an order deferring the case pending a ruling on the parties’ anticipated motions for summary judgment in the putative shareholder class action, or until otherwise agreed to by the parties. On January 9, 2019, a similar shareholder derivative complaint was filed in the Superior Court of Gwinnett County, Georgia, which is stayed pending a ruling on the parties' anticipated motions for summary judgment in the putative shareholder class action, or until otherwise agreed by the parties. The defendants dispute the allegations in the derivative complaints and intend to vigorously defend against the claims. On February 1, 2019, Schultz Transfer Systems, Inc. filed a complaint against Fleetcor Technologies Operating Company, LLC (“Fleetcor LLC”) in the United States District Court for the Northern District of Georgia. The plaintiff alleges that it is a Fleetcor LLC customer and member of the Fuelman program, and that Fleetcor LLC overcharged the plaintiff for fees and fuel through the Fuelman program. Based on these allegations, the plaintiff asserts claims for breach of contract, breach of the covenant of good faith and fair dealing, fraud, fraudulent concealment, money had and received, and unjust enrichment. The plaintiff seeks to represent a class defined as all persons, including corporate entities, who were enrolled in the Fuelman program between June 2016 and the present. On April 1, 2019, the Company filed a motion to compel arbitration and to dismiss the case, which is pending with the court. The Company disputes the allegations in the complaint and intends to vigorously defend against these claims. Estimating an amount or range of possible losses resulting from litigation proceedings is inherently difficult and requires an extensive degree of judgment, particularly where the matters involve indeterminate claims for monetary damages, and are in the stages of the proceedings where key factual and legal issues have not been resolved. For these reasons, we are currently unable to predict the ultimate timing or outcome of, or reasonably estimate the possible losses or a range of possible losses resulting from the matters described above.
