[1] During the quarter ended September 30, 2017, KFC refranchising gains related primarily to the sale of restaurants in the Netherlands and Australia. These gains were partially offset by a loss recorded related to our planned refranchising of KFC Turkey, which was classified as held-for-sale during the quarter ended September 30, 2017. While the sales price we expect to receive for KFC Turkey exceeds the carrying value of the restaurants being sold, this pending transaction would represent a substantially complete liquidation of our KFC Turkey foreign entity. Accordingly, we are required to include accumulated translation losses associated with our KFC Turkey business within our held-for-sale impairment evaluations. As such, we recorded a $51 million non-cash charge within Refranchising (gain) loss that represents the excess of the book value of our KFC Turkey business, which included the accumulated translation losses and a proportionate amount of the KFC Turkey goodwill balance, over the expected sales price.

[2] During the quarter ended September 30, 2017, we recorded a $25 million Refranchising loss related to executing a master franchising agreement that consolidated our existing Pizza Hut Korea franchise base under a single master franchisee. This loss included writing off $12 million of accumulated translation losses as this transaction resulted in a substantially complete liquidation of our Pizza Hut Korea foreign entity.

[3] Net refranchising gains for Taco Bell Division for both the quarter and year to date ended September 30, 2017, relate to refranchising Taco Bell restaurants in the U.S.

[4] Represents depreciation reductions arising from KFC restaurants we offered to sell. See Note 5.

[5] Represents costs associated with the KFC U.S. Acceleration Agreement and the Pizza Hut U.S. Transformation Agreement. See Note 5.

[6] Amounts include charges associated with YUM's Strategic Transformation Initiatives of $4 million and $15 million for the quarter and year to date ended September 30, 2017, respectively, and $30 million and $34 million, respectively, for the quarter and year to date ended September 30, 2016. Year to date 2017 amounts also include non-cash charges associated with share-based compensation of $18 million. See Note 5.
