Gain upon acquisition of Little Sheep															$ 0	[19]	$ 74	[19]

[1] Includes a non-cash charge of $295 million in the third quarter related primarily to the impairment of Little Sheep intangible assets and net U.S. refranchising gains of $17 million, $28 million, $37 million and $9 million in the first, second, third and fourth quarters, respectively. See Note 4 for further discussion.

[2] b)Includes a non-cash gain recognized upon acquisition of Little Sheep of $74 million in the first quarter, refranchising losses associated with the Pizza Hut UK dine-in business of $24 million and $46 million in the first and fourth quarters, respectively, net U.S. refranchising gains of $45 million and $69 million in the first and fourth quarters, respectively and a pension settlement charge of $84 million in the fourth quarter. See Note 4 for further discussion. (c)Includes an after-tax charge of $75 million in the fourth quarter related to the repurchase of Senior Unsecured Notes. See Note 4 for further discussion.

[3] See Note 4 for further details on the acquisition of Little Sheep.

[4] Includes $118 million of premiums and other costs related to the extinguishment of debt. See Losses Related to the Extinguishment of Debt section of Note 4.

[5] Includes property, plant and equipment, net, goodwill, and intangible assets, net.

[6] Includes equity income from investments in unconsolidated affiliates of $26 million, $47 million and $47 million in 2013, 2012 and 2011, respectively, for China.

[7] China includes investments in 4 unconsolidated affiliates totaling $53 million, $72 million and $167 million for 2013, 2012 and 2011, respectively.

[8] We recorded an impairment charge of $222 million to write down Little Sheep's goodwill in 2013. See the Little Sheep Acquisition and Subsequent Impairment section of Note 4 for details.

[9] During the fourth quarter of 2012, we refranchised our remaining 331 Company-owned Pizza Hut dine-in restaurants in the United Kingdom ("UK"). The franchise agreement for these stores allows the franchisee to pay continuing franchise fees in the initial years of the agreement at a reduced rate. We agreed to allow the franchisee to pay these reduced fees in part as consideration for their assumption of lease liabilities related to underperforming stores that we anticipate they will close that were part of the refranchising. We recognize the estimated value of terms in franchise agreements entered into concurrently with a refranchising transaction that are not consistent with market terms as part of the upfront refranchising (gain) loss. Accordingly, upon the closing of this refranchising we recognized a loss of $53 million representing the estimated value of these reduced continuing fees. The associated deferred credit is being amortized into YRI's Franchise and license fees and income through 2016. This upfront loss largely contributed to a $70 million Refranchising loss we recognized during 2012 as a result of this refranchising. Also included in that loss was the write-off of $14 million in goodwill allocated to the Pizza Hut UK reporting unit. The remaining carrying value of goodwill allocated to our Pizza Hut UK business of $87 million, immediately subsequent to the aforementioned write-off, was determined not to be impaired as the fair value of the Pizza Hut UK reporting unit exceeded its carrying amount. For the year ended December 28, 2013, the refranchising of the Pizza Hut UK dine-in restaurants decreased Company sales by 18% and increased Franchise and license fees and income and Operating Profit by 2% and 3%, respectively, for the YRI Division versus 2012.

[10] During 2011, we recorded a $76 million charge in Refranchising (gain) loss as a result of our decision to refranchise or close all of our remaining Company-owned Pizza Hut UK dine-in restaurants, primarily to write down these restaurants' long-lived assets to their then estimated fair value. Impairment charges of Pizza Hut UK long-lived assets incurred as a result of this decision, including the charge mentioned in the previous sentence, reduced depreciation expense versus what would have otherwise been recorded by $13 million and $3 million for the years ended December 29, 2012 and December 31, 2011, respectively. These depreciation reductions were not allocated to the YRI segment resulting in depreciation expense in the YRI segment results continuing to be recorded at the rate which it was prior to the impairment charges being recorded for these restaurants.

[11] 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.

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

[13] 2012 and 2011 include depreciation reductions arising from the impairments of Pizza Hut UK restaurants we sold in 2012 of $13 million and $3 million, respectively. 2012 and 2011 include depreciation reductions arising from the impairment of KFC restaurants we offered to sell of $3 million and $10 million, respectively.

[14] 2013 and 2012 include pension settlement charges of $22 million and $87 million, respectively. 2013, 2012 and 2011 include approximately $5 million, $5 million and $21 million, respectively, of charges relating to U.S. G&A productivity initiatives and realignment of resources.

[15] 2013 represents impairment loss related to Little Sheep. 2011 represents net losses resulting from the LJS and A&W divestitures.

[16] 2012 includes gain upon acquisition of Little Sheep of $74 million.

[17] See Note 4 for further discussion of Refranchising gain (loss).

[18] Primarily includes cash, deferred tax assets and property, plant and equipment, net, related to our office facilities. 2011 includes $300 million of restricted cash related to the 2012 Little Sheep acquisition.

[19] See the Little Sheep Acquisition and Subsequent Impairment section of Note 4 for further discussion.
