Management reviews and analyzes business results excluding the effect of foreign currency translation, impairment and other charges and gains, as well as material regulatory and other income tax impacts, and bases incentive compensation plans on these results because the Company believes this better represents underlying business trends. Comparable sales and comparable guest counts are compared to the same period in the prior year and represent sales and transactions, respectively, at all restaurants, whether owned and operated by the Company or by franchisees, in operation at least thirteen months, including those temporarily closed. Some of the reasons restaurants may be temporarily closed include reimaging or remodeling, rebuilding, road construction, natural disasters, pandemics and acts of war, terrorism or other hostilities. Comparable sales exclude the impact of currency translation and the sales of any market considered hyperinflationary (generally identified as those markets whose cumulative inflation rate over a three-year period exceeds 100%), which management believes more accurately reflects the underlying business trends. Comparable sales are driven by changes in guest counts and average check, the latter of which is affected by changes in pricing and product mix. Systemwide sales include sales at all restaurants, whether owned and operated by the Company or by franchisees. Systemwide sales to loyalty members are comprised of all sales to customers who self-identify as a loyalty member when transacting with both Company-owned and operated and franchised restaurants. Systemwide sales to loyalty members are measured across 70 markets with loyalty programs. Systemwide sales to loyalty members represents an aggregation of the prior four quarters of sales to loyalty members active in the last 90 days of the respective quarter. While franchised sales are not recorded as revenues by the Company, management believes the information is important in understanding the Company's financial performance because these sales are the basis on which the Company calculates and records franchised revenues and are indicative of the financial health of the franchisee base. The Company's revenues consist of sales by Company-owned and operated restaurants and fees from franchised restaurants operated by conventional franchisees, developmental licensees and affiliates. Changes in Systemwide sales are primarily driven by comparable sales and net restaurant unit expansion. Free cash flow, defined as cash provided by operations less capital expenditures, and free cash flow conversion rate, defined as free cash flow divided by net income, are measures reviewed by management in order to evaluate the Company’s ability to convert net profits into cash resources, after reinvesting in the core business, that can be used to pursue opportunities to enhance shareholder value.
