All adjustments were comprised of normal recurring adjustments, except as noted in these Notes to Condensed Consolidated Financial Statements. During the third quarter of fiscal 2021, we made the decision to exit our operations in Mexico. All stores in Mexico were closed as of the end of the first quarter of fiscal 2022, and our International segment is now comprised of operations in Canada. Refer to Note&#160;2, Restructuring, for additional information. In order to align our fiscal reporting periods and comply with statutory filing requirements, we consolidate the financial results of our Mexico operations on a one-month lag. Our policy is to accelerate recording the effect of events occurring in the lag period that significantly affect our condensed consolidated financial statements. No such events were identified for the reported periods. Historically, we have generated a large proportion of our revenue and earnings in the fiscal fourth quarter, which includes the majority of the holiday shopping season in the U.S., Canada and Mexico. Due to the seasonal nature of our business, interim results are not necessarily indicative of results for the entire fiscal year. The interim financial statements and the related notes included in this Quarterly Report on Form&#160;10-Q should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form&#160;10-K for the fiscal year ended January 30, 2021. The first nine months of fiscal 2022 and fiscal 2021 included 39 weeks. In preparing the accompanying condensed consolidated financial statements, we evaluated the period from October 30, 2021, through the date the financial statements were issued for material subsequent events requiring recognition or disclosure.

Mexico Exit and Strategic Realignment In March 2020 the World Health Organization declared the outbreak of novel coronavirus disease (&#x201c;COVID-19&#x201d;) as a pandemic. The COVID-19 pandemic has had significant impacts on, for example, the economic conditions of the markets in which we operate, customer shopping behaviors, the role of technology in peoples&#x2019; lives and the way we meet their needs. In light of these changes, we are adapting our Building the New Blue Strategy to ensure that our focus and resources are closely aligned with the opportunities we see in front of us. As a result, in the third quarter of fiscal 2021, we made the decision to exit our operations in Mexico and began taking other actions to more broadly align our organizational structure in support of our strategy.   Charges incurred in our International segment primarily related to our decision to exit our operations in Mexico. All remaining stores in Mexico were closed in the first quarter of fiscal 2022 and we do not expect to incur material future restructuring charges related to the exit.  Charges incurred in our Domestic segment primarily related to actions taken to align our organizational structure in support of our strategy. During the nine months ended October 30, 2021, we recorded a $44 million credit primarily due to a reduction in expected termination benefits resulting from adjustments to previously planned organizational changes and higher-than-expected employee retention.  As we continue to evolve our Building the New Blue Strategy, it is possible that we will incur material future restructuring costs, but we are unable to forecast the timing and magnitude of such costs. All charges incurred related to the exit from Mexico and strategic realignment described above were from continuing operations and were presented as follows ($ in millions):                                                           Statement ofThree Months Ended October 30, 2021 Nine Months Ended October 30, 2021 Earnings LocationDomestic International Total Domestic International TotalInventory markdownsCost of sales$ -  $ -  $ -  $ -  $ (6)  $ (6) Asset impairmentsRestructuring charges  -    (1)    (1)    -    6&#160;    6&#160; Termination benefitsRestructuring charges  -    -    -    (44)    (1)    (45)   $ -  $ (1)  $ (1)  $ (44)  $ (1)  $ (45)                                                      Statement ofThree and Nine Months Ended October 31, 2020 Earnings LocationDomestic International TotalInventory markdownsCost of sales$ -  $ 36&#160;  $ 36&#160; Asset impairmentsRestructuring charges  10&#160;    48&#160;    58&#160; Termination benefitsRestructuring charges  36&#160;    18&#160;    54&#160;       $ 46&#160;  $ 102&#160;  $ 148&#160;                                    Statement ofCumulative Amount as of October 30, 2021 Earnings LocationDomestic International TotalInventory markdownsCost of sales$ -  $ 17&#160;  $ 17&#160; Asset impairments(1)Restructuring charges  10&#160;    63&#160;    73&#160; Termination benefitsRestructuring charges  79&#160;    19&#160;    98&#160; Currency translation adjustmentRestructuring charges  -    39&#160;    39&#160; Other(2)Restructuring charges  -    5&#160;    5&#160;       $ 89&#160;  $ 143&#160;  $ 232&#160; (1)Remaining net carrying value approximates fair value and was immaterial as of October 30, 2021.(2)Other charges are primarily comprised of contract termination costs.

Fair Value Measurements Fair value measurements are reported in one of three levels based on the lowest level of significant input used: Level 1 (unadjusted quoted prices in active markets); Level 2 (observable market inputs, other than quoted prices included in Level 1); and Level 3 (unobservable inputs that cannot be corroborated by observable market data). Recurring Fair Value Measurements Financial assets and liabilities accounted for at fair value were as follows ($ in millions):                                              Fair Value at  Balance Sheet Location(1)Fair Value Hierarchy October 30, 2021 January 30, 2021 October 31, 2020Assets                  Money market funds(2) Cash and cash equivalentsLevel 1  $ 313&#160;  $ 1,575&#160;  $ 4,119&#160; Time deposits(3) Cash and cash equivalentsLevel 2    625&#160;    865&#160;    84&#160; Time deposits(3) Short-term investments  Level 2    -    -    545&#160; Time deposits(3) Other current assets  Level 2    -    65&#160;    100&#160; Interest rate swap derivative instruments(4) Other current assets  Level 2    -    -    7&#160; Interest rate swap derivative instruments(4) Other assets  Level 2    58&#160;    91&#160;    95&#160; Marketable securities that fund deferred compensation(5)Other assets  Level 1    54&#160;    53&#160;    51&#160; (1)Balance sheet location is determined by length to maturity.(2)Valued at quoted market prices in active markets.(3)Valued at face value plus accrued interest, which approximates fair value.(4)Valued using readily observable market inputs. These instruments are custom, over-the-counter contracts with various bank counterparties that are not traded on an active market. See Note 5, Derivative Instruments, for additional information.(5)Valued using select mutual fund performance that trade with sufficient frequency and volume to obtain pricing information on an ongoing basis.  Fair Value of Financial Instruments The fair values of cash, receivables, accounts payable and other payables approximated their carrying values because of the short-term nature of these instruments. If these instruments were measured at fair value in the financial statements, they would be classified as Level 1 in the fair value hierarchy. Fair values for other investments held at cost are not readily available, but we estimate that the carrying values for these investments approximate their fair values. Long-term debt is presented at carrying value on our Condensed Consolidated Balance Sheets. If our long-term debt were recorded at fair value, it would be classified as Level 2 in the fair value hierarchy. Long-term debt balances were as follows ($&#160;in&#160;millions):                                                             October 30, 2021 January 30, 2021 October 31, 2020     Fair Value Carrying Value Fair Value Carrying Value Fair Value Carrying ValueLong-term debt(1)$ 1,257  $ 1,208  $ 1,331&#160;  $ 1,241&#160;  $ 1,954  $ 1,902 (1)Excludes debt discounts, issuance costs and finance lease obligations. </us-gaap:FairValueDisclosuresTextBlock>

Derivative Instruments We manage our economic and transaction exposure to certain risks by using foreign exchange forward contracts to hedge against the effect of Canadian dollar exchange rate fluctuations on a portion of our net investment in our Canadian operations. We also use interest rate swaps to mitigate the effect of interest rate fluctuations on our $650 million principal amount of notes due March 15, 2021 (&#x201c;2021 Notes&#x201d;), prior to their retirement in December 2020, and on our $500 million principal amount of notes due October&#160;1,&#160;2028 (&#x201c;2028 Notes&#x201d;). In addition, we use foreign currency forward contracts not designated as hedging instruments to manage the impact of fluctuations in foreign currency exchange rates relative to recognized receivable and payable balances denominated in non-functional currencies. Our derivative instruments designated as net investment hedges and interest rate swaps are recorded on our Condensed Consolidated Balance Sheets at fair value. See Note 4, Fair Value Measurements, for gross fair values of our outstanding derivative instruments and corresponding fair value classifications.

Debt Short-Term Debt U.S. Revolving Credit Facility On May 18, 2021, we entered into a $1.25 billion five year senior unsecured revolving credit facility agreement (the &#x201c;Five-Year Facility Agreement&#x201d;) with a syndicate of banks. The Five-Year Facility Agreement replaced the previous $1.25 billion senior unsecured revolving credit facility (the &#x201c;Previous Facility&#x201d;) with a syndicate of banks, which was originally scheduled to expire in April 2023, but was terminated on May 18, 2021. The Five-Year Facility Agreement permits borrowings of up to $1.25 billion and expires in May 2026. There were no borrowings outstanding under the Five-Year Facility Agreement as of October 30, 2021, or the Previous Facility as of January 30, 2021, and October 31, 2020.

On August&#160;24, 2021, we announced our plan to repurchase more than $2.5 billion of shares in fiscal 2022.
