Description of Business	Description of Business FLEETCOR Technologies, Inc. (the "Company", "we", "us" and "our") is a leading global provider of digital payment solutions that enables businesses to control purchases and make payments more effectively and efficiently. Since its incorporation in 2000, FLEETCOR has continued to deliver on its mission: to provide businesses with “a better way to pay”. FLEETCOR has been a member of the S&P 500 since 2018 and trades on the New York Stock Exchange under the ticker FLT. FLEETCOR’s vision is that every payment is digital, every purchase is controlled, and every related decision is informed. Digital payments are faster and more secure than paper-based methods such as checks, and provide timely and detailed data which can be utilized to effectively reduce unauthorized purchases and fraud, automate data entry and reporting, and eliminate reimbursement processes. Combining this payment data with analytical tools delivers insights, which managers can use to better run their businesses. The Company's wide range of digitized solutions generally provides control, reporting, and automation benefits over the payment methods businesses often used, such as cash, paper checks, general purpose credit cards, as well as employee pay and reclaim processes. Our Corporate Payments solutions, which simplify and automate payments, are designed to help businesses streamline the back-office operations associated with making outgoing payments. Companies can save time, cut costs, and manage B2B payment processing more efficiently with our suite of Corporate Payment solutions, including accounts payable (AP) automation, virtual cards, cross-border payments, purchasing and T&E cards. Our Expense Management solutions can help control and monitor employee spending and includes Fuel, Tolls, and Lodging. These solutions are purpose-built to provide customers with greater control and visibility of employee spending when compared with less specialized payment methods, such as cash or general-purpose credit cards. The Company also provides several other payments solutions, including Gift and other B2B payment solutions. Our proprietary processing and card management solutions provide customers with capabilities including: customizable user-level controls, detailed transaction reporting, programmable alerts, configurable networks, contract price validation and audit, and tax management and reporting. Our customers can use these data, controls and tools to combat fraud and employee misuse, streamline expense administration and potentially lower their operating costs. We utilize both proprietary and third-party payment acceptance networks to deliver our solutions. In our proprietary networks, which tend to be geographically distinct, transactions are processed on systems operated by us, and only at select participating merchants with whom we’ve contracted directly for acceptance. Third-party networks are operated by independent parties, and tend to be more broadly accepted, which is the primary benefit compared with our proprietary networks. Mastercard and VISA are our primary third-party network partners in North America and Europe, respectively. We actively market and sell our solutions to current and prospective customers leveraging a multi-channel approach. This go-to-market strategy includes direct sales forces, comprehensive digital channels, and strategic partner relationships. Our capabilities are also offered through indirect sales channels (e.g., major oil companies and fuel marketers for Fuel, and retail establishments for Tolls) and on a branded or “white label” basis, indirectly through a broad range of resellers and partners across Fuel, Lodging, and Corporate Payments. In doing so, we leverage their sales networks to expand our reach into new customer segments, new industry verticals, and new geographies faster and at a significantly lower cost. The Company has three reportable segments, North America, International, and Brazil. The Company reports these three segments as they reflect how we organize and manage our global employee base, manage operating performance, contemplate the differing regulatory environments across geographies, and help us isolate the impact of foreign exchange fluctuations on our financial results.
