Unless the context otherwise requires, the use of the terms "Best Buy," "we," "us" and "our" in these Notes to Consolidated Financial Statements refers to Best Buy Co., Inc. and, as applicable, its consolidated subsidiaries.

Our purpose is to enrich lives through technology. We have two reportable segments: Domestic and International. The Domestic segment is comprised of the operations, including our Best Buy Health business, in all states, districts and territories of the U.S. under various brand names including Best Buy, Best Buy Business, Best Buy Express, Best Buy Health, CST, Geek Squad, GreatCall, Lively, Magnolia and Pacific Kitchen and Home and the domain names bestbuy.com and greatcall.com. The International segment is comprised of all operations in Canada and Mexico under the brand names Best Buy, Best Buy Express, Best Buy Mobile, Geek Squad and the domain names bestbuy.ca and bestbuy.com.mx.

During the third quarter of fiscal 2021 we made the decision to exit our operations in Mexico. In fiscal 2020 we acquired all of the outstanding shares of Critical Signal Technologies, Inc. (“CST”) and the predictive healthcare technology business of BioSensics, LLC (“BioSensics”). In fiscal 2019 we acquired all of the outstanding shares of GreatCall, Inc. (“GreatCall”). Refer to Note 2, Restructuring, and Note 3, Acquisitions, for additional information.

In March 2020 the World Health Organization declared the outbreak of novel coronavirus disease ("COVID-19") as a pandemic. Except where otherwise directed by state and local authorities, we made the decision for the health and safety of our customers and employees to move our stores to a contactless, curbside-only operating model in the fiscal first quarter. We also temporarily suspended in-home delivery, repair and consultation services. At the beginning of the fiscal second quarter, we started welcoming customers back into our stores by offering an in-store consultation service to customers, by appointment only. On June 15, 2020, we began allowing customers to shop without an appointment at more than 800 stores across the U.S. As of June 22, 2020, almost all of our stores were open for shopping. We continue to offer contactless curbside pick-up and in-store consultations for customers who prefer to shop that way.

In light of the uncertainty surrounding the impact of COVID-19 and to maximize liquidity, we executed a short-term draw on the full amount of our $1.25 billion five year senior unsecured revolving credit facility (the “Facility”) on March 19, 2020, that remained outstanding until July 27, 2020, when the amounts we had borrowed under the Facility were repaid in full. See Note 8, Debt, for additional information on the Facility. In March 2020 we also announced the temporary suspension of all share repurchases which we resumed in November 2020.

In the first quarter of fiscal 2021 we concluded that the COVID-19 pandemic’s impact on our store operations was a triggering event to review for potential impairments of our store assets. As a result of this analysis, we recorded an immaterial asset impairment charge for a small number of stores within Selling, general and administrative (“SG&A”) expenses. We also completed a review for potential impairments of our goodwill in the first quarter of fiscal 2021, concluding that no impairment had occurred. A similar conclusion was reached upon completion of our annual goodwill impairment review during the fourth quarter of fiscal 2021.

On March 27, 2020, in response to the COVID-19 pandemic, the U.S. Congress enacted the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”), which among other things, contains provisions for deferral of the employer portion of social security taxes incurred through the end of calendar 2020 and an employee retention credit, a refundable payroll credit for 50% of wages and health benefits paid to employees not providing services due to the COVID-19 pandemic. As a result of the CARES Act, we deferred $142 million of qualified payroll taxes in fiscal 2021 and claimed the employee retention credit, which was treated as a government subsidy to offset related operating expenses. Based on our analysis of the CARES Act, we reduced our SG&A expenses in fiscal 2021 by $81 million for employee retention credits.

The COVID-19 pandemic remains an evolving situation. The extent of the impact of COVID-19 on our business and financial results will depend on future developments, including the duration of the outbreak within the markets in which we operate and the related impact on consumer confidence and spending, all of which are highly uncertain.

The consolidated financial statements include the accounts of Best Buy Co., Inc. and its consolidated subsidiaries. All intercompany balances and transactions are eliminated upon consolidation.

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 consolidated financial statements. Other than as disclosed in Note 2, Restructuring, no such events were identified for the reported periods that would have materially affected our financial condition, results of operations, liquidity or other factors had they been recorded during fiscal 2021, fiscal 2020 or fiscal 2019.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. ("GAAP") requires us to make estimates and assumptions. These estimates and assumptions affect the reported amounts in the consolidated financial statements, as well as the disclosure of contingent liabilities. Future results could be materially affected if actual results were to differ from these estimates and assumptions.

Fiscal Year

Our fiscal year ends on the Saturday nearest the end of January. Fiscal 2021, fiscal 2020 and fiscal 2019 included 52 weeks.

Adopted Accounting Pronouncements

In the first quarter of fiscal 2021 we prospectively adopted the following Accounting Standards Updates ("ASUs") issued by the Financial Accounting Standards Board, all of which had an immaterial impact on our results of operations, cash flows and financial position.

ASU 2016-13, Measurement of Credit Losses on Financial Instruments

ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment

ASU 2018-13, Fair Value Measurement - Disclosure Framework (Topic 820)

ASU 2018-15, Intangibles-Goodwill and Other - Internal Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract

Segment Information

Our business is organized into two reportable segments: Domestic (which is comprised of all states, districts and territories of the U.S.) and International (which is comprised of all operations in Canada and Mexico). Our chief operating decision maker ("CODM") is our Chief Executive Officer. Our CODM has ultimate responsibility for enterprise decisions, including determining resource allocation for, and monitoring the performance of, the consolidated enterprise, the Domestic reportable segment and the International reportable segment.

Our CODM relies on internal management reporting that analyzes enterprise results to the net earnings level and reportable segment results to the operating income level. We aggregate our Best Buy Domestic and Best Buy Health operating segments into one Domestic reportable segment. We also aggregate our Canada and Mexico businesses into one International operating segment, which represents the International reportable segment.

Business Combinations

We account for business combinations under the acquisition method of accounting. This method requires the recording of acquired assets and assumed liabilities at their acquisition date fair values. The excess of the purchase price over the fair value of assets acquired and liabilities assumed is recorded as goodwill. Results of operations related to business combinations are included prospectively beginning with the date of acquisition and transaction costs related to business combinations are recorded within SG&A.

Cash, Cash Equivalents and Restricted Cash

Cash primarily consists of cash on hand and bank deposits. Cash equivalents consist of money market funds, commercial paper, corporate bonds and time deposits with an original maturity of three months or less when purchased. The amounts of cash equivalents as of January 30, 2021, and February 1, 2020, were $3,559 million and $1,668 million, respectively, and the weighted-average interest rates were 0.6% and 1.8%, respectively.

Cash, cash equivalents and restricted cash reported on our Consolidated Balance Sheets is reconciled to the total shown on our Consolidated Statements of Cash Flows as follows ($ in millions):

-

	January 30, 2021		February 1, 2020		February 2, 2019
Cash and cash equivalents	$	5,494	$	2,229	$	1,980
Restricted cash included in Other current assets		131		126		204
Total cash, cash equivalents and restricted cash	$	5,625	$	2,355	$	2,184

Amounts included in restricted cash are primarily restricted to use for workers' compensation and general liability insurance claims.

Receivables

Receivables consist primarily of amounts due from vendors for various vendor funding programs, banks for customer credit card and debit card transactions and mobile phone network operators for device sales and commissions. Receivables are stated at their carrying values, net of a reserve for expected credit losses, which is primarily based on historical collection trends. Our allowances for uncollectible receivables were $38 million and $24 million as of January 30, 2021, and February 1, 2020, respectively. We had $88 million and $32 million of write-offs in fiscal 2021 and fiscal 2020, respectively.

Merchandise Inventories

Merchandise inventories are recorded at the lower of cost or net realizable value. The weighted average method is used to determine the cost of inventory which includes costs of in-bound freight to move inventory into our distribution centers. Also included in the cost of inventory are certain vendor allowances. Costs associated with storing and transporting merchandise inventories to our retail stores are expensed as incurred and included in cost of sales.

Our inventory valuation also reflects markdown adjustments for the excess of the cost over the net recovery we expect to realize from the ultimate disposition of inventory, including consideration of any rights we may have to return inventory to vendors for a refund, and establishes a new cost basis. Subsequent changes in facts or circumstances do not result in the reversal of previously recorded markdown adjustments or an increase in the newly established cost basis.

Our inventory valuation reflects adjustments for physical inventory losses (resulting from, for example, theft). Physical inventory is maintained through a combination of full location counts (typically once per year) and more regular cycle counts.

Property and Equipment

Property and equipment is recorded at cost. We depreciate property and equipment to its residual value using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are depreciated over the shorter of their estimated useful lives or the period from the date the assets are placed in service to the end of the lease term, which includes optional renewal periods if they are reasonably certain. Accelerated depreciation methods are generally used for income tax purposes.

When property is retired or otherwise disposed of, the cost and accumulated depreciation are removed from our Consolidated Balance Sheets and any resulting gain or loss is reflected on our Consolidated Statements of Earnings.

Repairs and maintenance costs are expensed as incurred. Major renewals or replacements that substantially extend the useful life of an asset are capitalized and depreciated.

Costs associated with the acquisition or development of software for internal use are capitalized and amortized over the expected useful life of the software, generally from two years to five years. A subsequent addition, modification or upgrade to internal-use software is capitalized to the extent that it enhances the software's functionality. Capitalized software is included in Fixtures and equipment on our Consolidated Balance Sheets. Software maintenance and training costs are expensed in the period incurred. The costs of developing software for sale to customers is expensed as incurred until technological feasibility is established, which generally leads to expensing substantially all costs.

Estimated useful lives by major asset category are as follows (in years):



Asset Category	Useful Life
Buildings	5-35
Leasehold improvements	2-10
Fixtures and equipment	2-15

Impairment of Long-Lived Assets

Long-lived assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. When evaluating long-lived assets with impairment indicators for potential impairment, we first compare the carrying value of the asset to its estimated undiscounted future cash flows. If the sum of the estimated undiscounted future cash flows is less than the carrying value of the asset, we calculate an impairment loss. The impairment loss calculation compares the carrying value of the asset to its estimated fair value, which is typically based on estimated discounted future cash flows. We recognize an impairment loss if the amount of the asset's carrying value exceeds the asset's estimated fair value.

We evaluate locations for triggering events on a quarterly basis. For store locations, our primary indicator that asset carrying values may not be recoverable is negative store operating income for the most recent 12-month period. We also monitor other factors when evaluating store locations for impairment, including significant changes in the manner of use or expected life of the assets or significant changes in our business strategies.

When reviewing long-lived assets for impairment, we group long-lived assets with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. For example, long-lived assets deployed at store locations are reviewed for impairment at the individual store level, which involves comparing the net carrying value of all assets to the net cash flow projections for each store. In addition, we conduct separate impairment reviews at other levels as appropriate, for example, to evaluate potential impairment of assets shared by several areas of operations, such as information technology systems.

Leases

The majority of our lease obligations are real estate operating leases used in our retail and distribution operations. Our finance leases are primarily equipment-related. For any lease with an initial term in excess of 12 months, the related lease assets and liabilities are recognized on our Consolidated Balance Sheets as either operating or finance leases at the inception of an agreement where it is determined that a lease exists. We have lease agreements that contain both lease and non-lease components. For lease agreements entered into or reassessed after the adoption of Accounting Standard’s Codification 842, Leases, in fiscal 2020, we have elected to combine lease and non-lease components for all classes of assets. Leases with an initial term of 12 months or less are not recorded on our Consolidated Balance Sheets; we recognize lease expense for these leases on a straight-line basis over the lease term.

Operating lease assets represent the right to use an underlying asset for the lease term and operating lease liabilities represent the obligation to make lease payments arising from the lease. These assets and liabilities are recognized based on the present value of future payments over the lease term at the commencement date. We estimate the incremental borrowing rate for each lease based on an evaluation of our credit ratings and the prevailing market rates for collateralized debt in a similar economic environment with similar payment terms and maturity dates commensurate with the terms of the lease. Our operating leases also typically require payment of real estate taxes, common area maintenance and insurance. These components comprise the majority of our variable lease cost and are excluded from the present value of our lease obligations. In instances where they are fixed, they are included due to our election to combine lease and non-lease components. Operating lease assets also include prepaid lease payments and initial direct costs and are reduced by lease incentives. Our lease terms generally do not include options to extend or terminate the lease unless it is reasonably certain that the option will be exercised. Fixed payments may contain predetermined fixed rent escalations. We recognize the related rent expense on a straight-line basis from the commencement date to the end of the lease term.

Goodwill and Intangible Assets

Goodwill

Goodwill is the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. We test goodwill for impairment annually in the fiscal fourth quarter or whenever events or circumstances indicate the carrying value may not be recoverable. We monitor the existence of potential impairment indicators throughout the fiscal year. We test for goodwill impairment at the reporting unit level. Reporting units are determined by identifying components of operating segments which constitute businesses for which discrete financial information is available and is regularly reviewed by segment management. No components were aggregated in arriving at our reporting units. We have goodwill in two reporting units – Best Buy Domestic and Best Buy Health – with carrying values of $444 million and $542 million, respectively, as of January 30, 2021.

Our detailed impairment testing involves comparing the fair value of each reporting unit with its carrying value, including goodwill. Fair value reflects the price a potential market participant would be willing to pay for the reporting unit in an arms-length transaction and typically requires analysis of discounted cash flows and other market information, such as trading multiples and other observable metrics. If the fair value of a reporting unit exceeds its carrying value, then it is concluded that no goodwill impairment has occurred. If the carrying value of a reporting unit exceeds its fair value, we recognize an impairment loss in an amount equal to the excess, not to exceed the total amount of goodwill allocated to that reporting unit.

Intangible Assets

Our valuation of identifiable intangible assets acquired is based on information and assumptions available to us at the time of acquisition, using income and market approaches to determine fair value, as appropriate.

We amortize our definite-lived intangible assets over the estimated useful life of the asset. We review these assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets might not be recoverable and monitor for the existence of potential impairment indicators throughout the fiscal year. We record an impairment loss for any portion of the carrying value that is not recoverable.

Derivatives

Net Investment Hedges

We use 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. The contracts have terms of up to 12 months. For a net investment hedge, we recognize changes in the fair value of the derivative as a component of foreign currency translation within other comprehensive income to offset a portion of the change in translated value of the net investment being hedged, until the investment is sold or liquidated. We limit recognition in net earnings of amounts previously recorded in other comprehensive income to circumstances such as complete or substantially complete liquidation of the net investment in the hedged foreign operation. We report the gains and losses, if any, related to the amount excluded from the assessment of hedge effectiveness in net earnings.

Interest Rate Swaps

We utilized "receive fixed-rate, pay variable-rate" interest rate swaps to mitigate the effect of interest rate fluctuations on our $650 million principal amount of notes due March 15, 2021 (“2021 Notes”) prior to their retirement in December 2020, and on our $500 million principal amount of notes due October 1, 2028 (“2028 Notes”). Our interest rate swap contracts are considered perfect hedges because the critical terms and notional amounts match those of our fixed-rate debt being hedged and are, therefore, accounted for as fair value hedges using the shortcut method. Under the shortcut method, we recognize the change in the fair value of the derivatives with an offsetting change to the carrying value of the debt. Accordingly, there is no impact on our Consolidated Statements of Earnings from the fair value of the derivatives.

Derivatives Not Designated as Hedging Instruments

We use foreign currency forward contracts to manage the impact of fluctuations in foreign currency exchange rates relative to recognized receivable and payable balances denominated in non-functional currencies. The contracts generally have terms of up to 12 months. These derivative instruments are not designated in hedging relationships and, therefore, we record gains and losses on these contracts directly to our Consolidated Statements of Earnings.

Fair Value

Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. To measure fair value, we use a three-tier valuation hierarchy based upon observable and non-observable inputs:

Level 1 — Unadjusted quoted prices that are available in active markets for identical assets or liabilities at the measurement date.

Level 2 — Significant other observable inputs available at the measurement date, other than quoted prices included in Level 1, either directly or indirectly, including:

• Quoted prices for similar assets or liabilities in active markets;

• Quoted prices for identical or similar assets or liabilities in non-active markets;

• Inputs other than quoted prices that are observable for the asset or liability; and

• Inputs that are derived principally from or corroborated by other observable market data.

Level 3 — Significant unobservable inputs that cannot be corroborated by observable market data and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions.

The fair value hierarchy requires the use of observable market data when available. In instances where the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability.

Assets and liabilities that are measured at fair value on a nonrecurring basis relate primarily to our tangible fixed assets, goodwill and other intangible assets, which are remeasured when the derived fair value is below carrying value on our Consolidated Balance Sheets. For these assets, we do not periodically adjust carrying value to fair value, except in the event of impairment. When we determine that impairment has occurred, the carrying value of the asset is reduced to fair value and the difference is recorded within SG&A and Restructuring charges on our Consolidated Statements of Earnings for non-restructuring and restructuring charges, respectively.

Fair value remeasurements are based on significant unobservable inputs (Level 3). Fixed asset fair values are primarily derived using a discounted cash flow (“DCF”) model to estimate the present value of net cash flows that the asset or asset group was expected to generate. The key inputs to the DCF model generally include our forecasts of net cash generated from revenue, expenses and other significant cash outflows, such as capital expenditures, as well as an appropriate discount rate.

Insurance

We are self-insured for certain losses related to workers' compensation, medical and general liability claims; however, we obtain third-party excess insurance coverage to limit our exposure to certain claims. Some of these self-insured losses are managed through a wholly-owned insurance captive. Liabilities associated with these losses include estimates of both claims filed and losses incurred but not yet reported. We utilize valuations provided by qualified, independent third-party actuaries as well as internal insurance and risk expertise. Our self-insured liabilities included on our Consolidated Balance Sheets were as follows ($ in millions):



	January 30, 2021		February 1, 2020
Accrued liabilities	$	101	$	75
Long-term liabilities		45		46
Total	$	146	$	121

Income Taxes

We account for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. We record a valuation allowance to reduce the carrying amounts of deferred tax assets if it is more likely than not that such assets will not be realized.

In determining our provision for income taxes, we use an annual effective income tax rate based on annual income, permanent differences between book and tax income and statutory income tax rates. The effective income tax rate also reflects our assessment of the ultimate outcome of tax audits. We adjust our annual effective income tax rate as additional information on outcomes or events becomes available. Discrete events, such as audit settlements or changes in tax laws, are recognized in the period in which they occur.

Our income tax returns are periodically audited by U.S. federal, state and local and foreign taxing authorities. At any one time, multiple tax years are subject to audit by the various taxing authorities. In evaluating the exposures associated with our various tax filing positions, we may record a liability for such exposures. A number of years may elapse before a particular matter, for which we have established a liability, is audited and fully resolved or clarified. We adjust our liability for unrecognized tax benefits and income tax provisions in the period in which an uncertain tax position is effectively settled, the statute of limitations expires for the relevant taxing authority to examine the tax position or when more information becomes available. We include our liability for unrecognized tax benefits, including accrued penalties and interest, in Long-term liabilities on our Consolidated Balance Sheets and in Income tax expense on our Consolidated Statements of Earnings.

Accrued Liabilities

The major components of accrued liabilities are sales tax liabilities, advertising accruals, sales return reserves, customer deposits and insurance liabilities.

Long-Term Liabilities

The major components of long-term liabilities are unrecognized tax benefits, income tax liabilities and self-insurance reserves.

Foreign Currency

Foreign currency denominated assets and liabilities are translated into U.S. dollars using the exchange rates in effect at our Consolidated Balance Sheet dates. For operations reported on a one-month lag, we use the exchange rates in effect one month prior to our Consolidated Balance Sheet dates. Results of operations and cash flows are translated using the average exchange rates throughout the periods. The effect of exchange rate fluctuations on the translation of assets and liabilities is included as a component of shareholders' equity in accumulated other comprehensive income. Gains and losses from foreign currency transactions, which are included in SG&A, have not been significant in any period presented.

Revenue Recognition

We generate revenue from the sale of products and services, both as a principal and as an agent. Revenue is recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the transaction price consideration that we expect to receive in exchange for those goods or services. Our revenue excludes sales and usage-based taxes collected and is reported net of sales refunds, which includes an estimate of future returns and contract cancellations based on historical refund rates, with a corresponding reduction to cost of sales. We defer the revenue associated with any unsatisfied performance obligation until the obligation is satisfied, i.e., when control of a product is transferred to the customer or a service is completed.

Product Revenue

Product revenue is recognized when the customer takes physical control, either in our stores or at their home. Any fees charged to customers for delivery are a component of the transaction price and are recognized when delivery has been completed. We use delivery information at an individual contract level to determine when to recognize revenue for delivered products and any related delivery fee revenue.

In most cases, we are the principal to product contracts as we have control of the physical products prior to transfer to the customer. Accordingly, revenue is recognized on a gross basis. For certain sales, primarily activation-based software licenses and third-party stored-value cards, we are the sales agent providing access to the content and recognize commission revenue net of amounts due to third parties who fulfill the performance obligation. For these sales, control passes upon providing access of the content to the customer.

Warranty obligations associated with the sale of our exclusive brands products are assurance-type warranties that are a guarantee of the product’s intended functionality and, therefore, do not represent a distinct performance obligation within the context of the contract.

Services - When we are the principal

We recognize revenue for services, such as installation, set-up, software troubleshooting, product repair, consultation and educational classes once the service is completed, as this is when the customer has the ability to direct the use of and obtain the benefits of the service or serviced product. Payment terms are typically at the point of sale, but may also occur upon completion of the service. Our service contracts are primarily with retail customers and merchandise vendors (for factory warranty repairs).

For technical support membership contracts (for example, our Total Tech Support offering), we are responsible for fulfilling the support services to customers. These contracts have terms ranging from one month to three years and typically contain several performance obligations. Payment for the membership contracts is due at the start of the contract period. We have determined that our contracts do not include a significant financing component. The primary purpose of our payment terms is to provide customers with a simplified method of purchasing our services, not to provide customers with financing. For performance obligations provided over time, we recognize revenue on a usage basis, an input method of measuring progress over the related contract term. This method is derived by analysis of historical utilization patterns as this depicts when customers use the services and, accordingly, when delivery of the performance obligation occurs. There is judgment in (1) determining the level at which we apply a portfolio approach to these contracts; (2) measuring the relative standalone selling price for performance obligations within these contracts to the extent that they are only bundled and sold to customers with other performance obligations, or alternatively, using a cost-plus margin approach; and (3) assessing the pattern of delivery across multiple portfolios of customers, including estimating current and future usage patterns. When insufficient history is available to estimate usage, we generally recognize revenue ratably over the life of the contract.

Services - When we are the agent

On behalf of third-party underwriters, we sell various hardware protection plans to customers that provide extended warranty coverage on their device purchases. Such plans have terms ranging from one month to five years. Payment is due at the point of sale. Third-party underwriters assume the risk associated with the coverage and are primarily responsible for fulfillment. We record the net commissions (the amount charged to the customer less the premiums remitted to the underwriter) as revenue at a point in time when the corresponding product revenue is recognized. In addition, in some cases we are eligible to receive profit-sharing payments, a form of variable consideration, which are dependent upon the financial performance of the underwriter’s protection plan portfolio. We do not share in any losses of the portfolio. We record any profit share as revenue once the uncertainty associated with the portfolio period, which is calendar-year based, is no longer constrained using the expected value method. This typically occurs during our fiscal fourth quarter, with payment of the profit share occurring in the subsequent fiscal year. Service and commission revenues earned from the sale of extended warranties represented approximately 2% of revenue in fiscal 2021, fiscal 2020 and fiscal 2019.

We earn commissions from mobile network carriers to sell service contracts on their platforms. Revenue is recognized when control passes at a point in time upon sale of the contract and activation of the customer on the provider’s platform. The time between when we activate the service with the customer and when we receive payment from the content provider is generally within 30 to 60 days, which is after control has passed. Activation commissions are subject to repayment to the carrier primarily in the event of customer cancellation for specified time periods after the sale. Commission revenue from mobile network carriers is reported net of the expected cancellations, which we estimate based on historical cancellation rates.

Credit Card Revenue

We offer promotional financing and credit cards issued by third-party banks that manage and directly extend credit to our customers. Approximately 25% of revenue in fiscal 2021, fiscal 2020 and fiscal 2019 was transacted using one of our branded cards. We provide a license to our brand and marketing services, and we facilitate credit applications in our stores and online. The banks are the sole owners of the accounts receivable generated under the program and, accordingly, we do not hold any customer receivables related to these programs and act as an agent in the financing transactions with customers. We are eligible to receive a profit share from certain of our banking partners based on the annual performance of their corresponding portfolio, and we receive quarterly payments based on forecasts of full-year performance. This is a form of variable consideration. We record such profit share as revenue over time using the most likely amount method, which reflects the amount earned each quarter when it is determined that the likelihood of a significant revenue reversal is not probable, which is typically quarterly. Profit-share payments occur quarterly, shortly after the end of each program quarter.

Best Buy Gift Cards

We sell Best Buy gift cards to our customers in our retail stores, online and through select third parties. Our gift cards do not expire. We recognize revenue from gift cards when the card is redeemed by the customer. We also recognize revenue for the portion of gift card values that is not expected to be redeemed ("breakage"). We estimate breakage based on historical patterns and other factors, such as laws and regulations applicable to each jurisdiction. We recognize breakage revenue using a method that is consistent with customer redemption patterns. Typically, over 90% of gift card redemptions (and therefore recognition of over 90% of gift card breakage revenue) occur within one year of issuance. There is judgment in assessing (1) the level at which we group gift cards for analysis of breakage rates, (2) redemption patterns, and (3) the ultimate value of gift cards which we do not expect to be redeemed. Gift card breakage income was $33 million, $35 million and $34 million in fiscal 2021, fiscal 2020 and fiscal 2019, respectively.

Sales Incentives

We frequently offer sales incentives that entitle our customers to receive a gift card at the time of purchase or an instant savings coupon that can be redeemed towards a future purchase. For sales incentives issued to customers that are only earned in conjunction with the purchase of products or services, the sales incentives represent an option that is a material right and, accordingly, is a performance obligation in the contract. The revenue allocated to these sales incentives is deferred as a contract liability and is based on the cards that are projected to be redeemed. We recognize revenue for this performance obligation when it is redeemed by the customer or when it is not expected to be redeemed. There is judgment in determining (1) the level at which we group incentives based on similar redemption patterns, (2) future redemption patterns, and (3) the ultimate number of incentives that we do not expect to be redeemed.

We also issue coupons that are not earned in conjunction with a purchase of a product or service, typically as part of targeted marketing activities. This is not a performance obligation, but is recognized as a reduction of the transaction price when redeemed by the customer.

Customer Loyalty Programs

We have customer loyalty programs which allow members to earn points for each purchase completed with us or when using our co-branded credit cards. Points earned enable members to receive a certificate that may be redeemed on future purchases. Depending on the customer's membership level within our loyalty program, certificate expirations typically range from 2 to 6 months from the date of issuance. Our loyalty programs represent customer options that provide a material right and, accordingly, are performance obligations for each applicable contract. The relative standalone selling price of points earned by our loyalty program members is deferred and included in Deferred revenue on our Consolidated Balance Sheets based on the percentage of points that are projected to be redeemed. We recognize revenue for this performance obligation over time when a certificate is estimated to be redeemed by the customer. There is inherent judgment in estimating the value of our customer loyalty programs as they are susceptible to factors outside of our influence, particularly customer redemption activity. However, we have significant experience in estimating the amount and timing of redemptions of certificates, based primarily on historical data.

Cost of Sales and Selling, General and Administrative Expenses

The following tables illustrate the primary costs classified in each major expense category.

Cost of Sales

Cost of products sold, including:

Freight expenses associated with moving merchandise inventories from our vendors to our distribution centers

Vendor allowances that are not a reimbursement of specific, incremental and identifiable costs

Cash discounts on payments to merchandise vendors

Physical inventory losses

Markdowns

Vendor Allowances

We receive funds from our merchandise vendors through a variety of programs and arrangements for product advertising and product placement, primarily in the form of allowances based on purchases or sales volumes. We recognize allowances based on purchases and sales as a reduction of cost of sales when the associated inventory is sold. Allowances for advertising and placement are recognized as a reduction of cost of sales ratably over the corresponding performance period. Funds that are determined to be a reimbursement of specific, incremental and identifiable costs incurred to sell a vendor's products are recorded as an offset to the related expense when incurred.

Advertising costs, which are included in SG&A, are expensed over the period in which the advertisement is customer-facing. Advertising costs consist primarily of digital and television advertisements, as well as support costs. Advertising expenses were $819 million, $840 million and $777 million in fiscal 2021, fiscal 2020 and fiscal 2019, respectively.

We apply the fair value recognition provisions of accounting guidance as they relate to our stock-based compensation, which requires us to recognize expense for the fair value of our stock-based compensation awards. Compensation expense is recognized over the period in which services are required. It is recognized on a straight-line basis, except where there are performance awards that vest on a graded basis, in which case the expense for these awards is front-loaded or recognized on a graded-attribution basis.
