[1] During the fourth quarter of 2012, we refranchised our remaining 331 Company-owned Pizza Hut dine-in restaurants in the United Kingdom ("UK"). During the quarter ended March 24, 2012 we recorded a loss of $21 million and a $4 million related income tax benefit due to the then planned refranchising of these restaurants.

[2] In the quarters ended March 23, 2013 and March 24, 2012, U.S. Refranchising (gain) loss primarily relates to gains on the sales of Taco Bell restaurants.

[3] Amounts have not been allocated to any segment for performance reporting purposes.

[4] Includes U.S. refranchising gains of $17 million and $45 million for the quarters ended March 23, 2013 and March 24, 2012, respectively, and a loss of $21 million related to the planned refranchising of our Pizza Hut UK dine-in business for the quarter ended March 24, 2012. See Note 4.

[5] Store closure (income) costs include the net gain or loss on sales of real estate on which we formerly operated a Company restaurant that was closed, lease reserves established when we cease using a property under an operating lease and subsequent adjustments to those reserves and other facility-related expenses from previously closed stores.
