[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 Mexico market-wide 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.
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.
