[1] Store closure (income) costs include the net gain or loss on sales of real estate on which we formerly operated a Company-owned 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. Remaining lease obligations for closed stores were not material at December 26, 2015 or December 27, 2014.

[2] In 2010 we refranchised our then-remaining Company-operated restaurants in Mexico. To the extent we owned it, we did not sell the real estate related to certain of these restaurants, instead leasing it to the franchisee. During 2015, we sold the real estate for approximately $58 million. While these proceeds exceeded the book value of the real estate, the sale represented a substantial liquidation of our Mexican foreign entities under GAAP. As such, the accumulated translation losses associated with our Mexican business were included in our loss on the sale. We recorded charges of $80 million representing the excess of the sum of the book value of the real estate and other related assets and our accumulated translation losses over the sales price. Consistent with the classification of the original market refranchising transaction, these charges were classified as Refranchising (gain) loss. Refranchising losses of $40 million were associated with both the KFC and Pizza Hut Divisions.Our KFC and Pizza Hut Divisions earned approximately $2 million and $1 million, respectively, of rental income in 2015 and $3 million and $1 million, respectively, of rental income in 2014 related to this real estate that transferred to the buyer subsequent to the sale of the real estate. We continue to earn U.S. dollar-denominated franchise fees, most of which are sales-based royalties, under our existing franchise contracts with our Mexico franchisee.

[3] China Accumulated impairment losses represent Little Sheep impairment, of which $160 million was recorded in 2014. See Note 4.

[4] During 2015 we recognized charges of $16 million within Refranchising (gain) loss associated with the refranchising of our company-owned Pizza Hut restaurants in Korea. While additional gains or losses may occur as the refranchising plans move forward, such amounts are not expected to be material at this time.
