[3] Our operating results presented herein reflect revenues from and expenses to support the Russian operations for KFC and Pizza Hut prior to the dates of sale or transfer (see Note 1), within their historical financial statement line items and operating segments. However, given our decision to exit Russia and our pledge to direct any future net profits attributable to Russia subsequent to the date of invasion to humanitarian efforts, we reclassed such net profits and losses subsequent to that date from the Division segment results in which they were earned to Unallocated Other income (expense). As a result, we reclassed net operating losses of $1 million from KFC Division Other income (expense) to Unallocated Other income (expense) during the year to date ended September 30, 2023, and net operating profit of $19 million and $30 million from Divisional Other income (expense) to Unallocated Other income (expense) during the quarter and year to date ended September 30, 2022, respectively. Additionally, we recorded income of $1 million and a charge of $3 million to Unallocated Other income (expense) during the quarter and year to date ended September 30, 2023, respectively, from the sale of our KFC Russia business.Also included in Unallocated Other income (expense) were $1 million in foreign exchange losses attributable to fluctuations in the value of the Russian Ruble during the year to date ended September 30, 2023, and foreign exchange losses of $1 million and foreign exchange gains of $15 million during the quarter and year to date ended September 30, 2022, respectively. Additionally, we recorded expense of $4 million to Corporate and unallocated G&A expenses during the year to date ended September 30, 2023, and income of $1 million and expense of $1 million to Unallocated Franchise and property expenses during the quarter and year to date ended September 30, 2023, respectively, for certain expenses related to the disposition of the businesses and other costs related to our exit from Russia. We recorded similar charges of $1 million and $3 million to Corporate and Unallocated G&A expenses and $1 million and $5 million to Unallocated Franchise and property expenses during the quarter and year to date ended September 30, 2022, respectively.
