[3] Our operating results for the year to date ended September 30, 2022, continue to reflect royalty revenues from and expenses to support the Russian operations for Pizza Hut prior to the date of transfer and for KFC for the entire quarter and year to date (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 have reclassed such net operating profits from the Division segment results in which they were earned to Corporate and unallocated Other income (expense). As a result, we reclassed net operating profits of $18 million and $44 million from KFC and Pizza Hut Other income (expense) to Unallocated Other (income) expense during the quarter and year to date ended September 30, 2022, respectively.Additionally, we have incurred certain expenses related to the transfer of the businesses and other one-time costs related to our exit from Russia which we have recorded within Corporate and unallocated. As a result of these other costs and expenses we have incurred, we recorded charges of $1 million to Corporate and unallocated G&A expenses and less than $1 million to Unallocated Franchise and property expenses during the quarter ended September 30, 2022. During the year to date ended September 30, 2022, we recorded charges of $3 million to Corporate and unallocated G&A expenses and $4 million to Unallocated Franchise and property expenses.
