[5] U.S. Refranchising (gain) loss in the years ended December 28, 2013 and December 29, 2012 is primarily due to gains on sales of Taco Bell restaurants. U.S. Refranchising (gain) loss in the year ended December 31, 2011 is primarily due to losses on sales of and offers to refranchise KFCs in the U.S. The non-cash impairment charges that were recorded related to our offers to refranchise these Company-owned KFC restaurants in the U.S. decreased depreciation expense versus what would have otherwise been recorded by $3 million and $10 million in the years ended December 29, 2012 and December 31, 2011, respectively. These depreciation reductions were not allocated to the U.S. segment resulting in depreciation expense in the U.S. segment results continuing to be recorded at the rate at which it was prior to the impairment charges being recorded for these restaurants.
