[1] See the Little Sheep Acquisition and Impairment section as well as the Refranchising (Gain) Loss section of Note 4 for further discussion. (b)Refranchising related impairment results from writing down the assets of restaurants or restaurant groups offered for refranchising, including certain instances where a decision has been made to refranchise restaurants that are deemed to be impaired. The fair value measurements used in our impairment evaluations were based on estimates of the sales prices we anticipated receiving from a buyer for the restaurant or restaurant groups (Level 3) or actual bids received from potential buyers (Level 2).
