To estimate future cash flows, we make certain assumptions about expected future operating performance, such as revenue growth, operating margins, risk-adjusted discount rates, and future economic and market conditions. If the long-lived assets of a restaurant are not recoverable based upon estimated future, undiscounted cash flows, we write the assets down to their fair value.
For assets identified as held for sale, we use the market approach and consider proceeds from similar asset sales. We assess impairment of restaurant-level assets based on the operating cash flows of the restaurant, expected proceeds from the sale of assets and our plans for restaurant closings.
