Background	'
	1.Business and Background
	CarMax, Inc. (“we,” “our,” “us,” “CarMax” and “the company”), including its wholly owned subsidiaries, is the largest retailer of used vehicles in the United States.  We operate in two reportable segments:  CarMax Sales Operations and CarMax Auto Finance (“CAF”).  Our CarMax Sales Operations segment consists of all aspects of our auto merchandising and service operations, excluding financing provided by CAF.  Our CAF segment consists solely of our own finance operation that provides vehicle financing through CarMax superstores.
	We were the first used vehicle retailer to offer a large selection of high quality used vehicles at low, no-haggle prices using a customer-friendly sales process in an attractive, modern sales facility.  We provide customers with a full range of related products and services, including the appraisal and purchase of vehicles directly from consumers; the financing of vehicle purchases through CAF and third-party financing providers; the sale of extended service plans (“ESP”) and guaranteed asset protection (“GAP”); and vehicle repair service.  Vehicles purchased through the appraisal process that do not meet our retail standards are sold to licensed dealers through on-site wholesale auctions.  At select locations we also sell new vehicles under franchise agreements.

Summary Of Significant Accounting Policies [Abstract]	'
Summary Of Significant Accounting Policies	'
	2.Summary of Significant Accounting Policies
	(A)  Basis of Presentation and Use of Estimates
	The consolidated financial statements include the accounts of CarMax and our wholly owned subsidiaries.  All significant intercompany balances and transactions have been eliminated in consolidation.  The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities.  Actual results could differ from those estimates.  Certain prior year amounts have been reclassified to conform to the current year’s presentation.  Amounts and percentages may not total due to rounding.
	(B)  Cash and Cash Equivalents
	Cash equivalents of $607.0 million as of February 28, 2014, and $430.3 million as of February 28, 2013, consisted of highly liquid investments with original maturities of three months or less.
	(C)  Restricted Cash from Collections on Auto Loan Receivables
	Cash accounts totaling $259.3 million as of February 28, 2014, and $224.3 million as of February 28, 2013, consisted of collections of principal and interest payments on securitized auto loan receivables that are restricted for payment to the securitization investors pursuant to the applicable securitization agreements.
	(D)  Marketable Securities
	The Company classifies all marketable securities as available-for-sale.  These securities consisted exclusively of variable-rate demand notes reported at fair value with unrealized gains and losses, net of taxes, excluded from net income and shown separately as a component of accumulated other comprehensive loss within shareholders' equity.  There were no marketable securities available-for-sale as of February 28, 2014 and 2013.
	Proceeds from the sales of marketable securities available-for-sale were $0.5 million and $30.3 million in fiscal 2014 and 2013, respectively.  There were no related gains or losses during fiscal 2014 and fiscal 2013.
	(E)  Accounts Receivable, Net
	Accounts receivable, net of an allowance for doubtful accounts, includes certain amounts due from third-party finance providers and customers and other miscellaneous receivables.  The allowance for doubtful accounts is estimated based on historical experience and trends.
	(F)  Securitizations
	We maintain a revolving securitization program composed of two warehouse facilities (“warehouse facilities”) that we use to fund auto loan receivables originated by CAF until we elect to fund them through a term securitization or alternative funding arrangement.  We sell the auto loan receivables to a wholly owned, bankruptcy-remote, special purpose entity that transfers an undivided percentage ownership interest in the receivables, but not the receivables themselves, to entities formed by third-party investors.  These entities issue asset-backed commercial paper or utilize other funding sources supported by the transferred receivables, and the proceeds are used to finance the securitized receivables.
	We typically use term securitizations to provide long-term funding for most of the auto loan receivables initially securitized through the warehouse facilities.  In these transactions, a pool of auto loan receivables is sold to a bankruptcy-remote, special purpose entity that, in turn, transfers the receivables to a special purpose securitization trust.  The securitization trust issues asset-backed securities, secured or otherwise supported by the transferred receivables, and the proceeds from the sale of the asset-backed securities are used to finance the securitized receivables.
	We are required to evaluate term securitization trusts for consolidation.  In our capacity as servicer, we have the power to direct the activities of the trusts that most significantly impact the economic performance of the trusts.  In addition, we have the obligation to absorb losses (subject to limitations) and the rights to receive any returns of the trusts, which could be significant.  Accordingly, we are the primary beneficiary of the trusts and are required to consolidate them.
	We recognize transfers of auto loan receivables into the warehouse facilities and term securitizations (“securitization vehicles”) as secured borrowings, which result in recording the auto loan receivables and the related non-recourse notes payable to the investors on our consolidated balance sheets.
	The securitized receivables can only be used as collateral to settle obligations of the securitization vehicles.  The securitization vehicles and investors have no recourse to our assets beyond the securitized receivables, the amounts on deposit in reserve accounts and the restricted cash from collections on auto loan receivables.  We have not provided financial or other support to the securitization vehicles that was not previously contractually required, and there are no additional arrangements, guarantees or other commitments that could require us to provide financial support to the securitization vehicles.
	See Notes 4 and 11 for additional information on auto loan receivables and non-recourse notes payable.
	(G)  Fair Value of Financial Instruments
	Due to the short-term nature and/or variable rates associated with these financial instruments, the carrying value of our cash and cash equivalents, restricted cash, accounts receivable, money market securities, accounts payable, short-term debt and long-term debt approximates fair value.  Our derivative instruments and mutual funds are recorded at fair value.  Auto loan receivables are presented net of an allowance for estimated loan losses.  See Note 6 for additional information on fair value measurements.
	(H)  Inventory
	Inventory is primarily comprised of vehicles held for sale or currently undergoing reconditioning and is stated at the lower of cost or market.  Vehicle inventory cost is determined by specific identification.  Parts and labor used to recondition vehicles, as well as transportation and other incremental expenses associated with acquiring and reconditioning vehicles, are included in inventory.
	(I)  Auto Loan Receivables, Net
	Auto loan receivables include amounts due from customers related to retail vehicle sales financed through CAF.  The receivables are presented net of an allowance for estimated loan losses.  The allowance for loan losses represents an estimate of the amount of net losses inherent in our portfolio of managed receivables as of the applicable reporting date and anticipated to occur during the following 12 months.  The allowance is primarily based on the credit quality of the underlying receivables, historical loss trends and forecasted forward loss curves.  We also take into account recent trends in delinquencies and losses, recovery rates and the economic environment.  The provision for loan losses is the periodic expense of maintaining an adequate allowance.
	An account is considered delinquent when the related customer fails to make a substantial portion of a scheduled payment on or before the due date.  In general, accounts are charged-off on the last business day of the month during which the earliest of the following occurs:  the receivable is 120 days or more delinquent as of the last business day of the month, the related vehicle is repossessed and liquidated, or the receivable is otherwise deemed uncollectible.  For purposes of determining impairment, auto loans are evaluated collectively, as they represent a large group of smaller-balance homogeneous loans, and therefore, are not individually evaluated for impairment.  See Note 4 for additional information on auto loan receivables.
	Interest income and expenses related to auto loans are included in CAF income.  Interest income on auto loan receivables is recognized when earned based on contractual loan terms.  All loans continue to accrue interest until repayment or charge-off.  Direct costs associated with loan originations are not considered material, and thus, are expensed as incurred.  See Note 3 for additional information on CAF income.
	(J)  Property and Equipment
	Property and equipment is stated at cost less accumulated depreciation and amortization.  Depreciation and amortization are calculated using the straight-line method over the shorter of the asset’s estimated useful life or the lease term, if applicable.  Property held under capital lease is stated at the lesser of the present value of the future minimum lease payments at the inception of the lease or fair value.  Amortization of capital lease assets is computed on a straight-line basis over the shorter of the initial lease term or the estimated useful life of the asset and is included in depreciation expense.  Costs incurred during new store construction are capitalized as construction-in-progress and reclassified to the appropriate fixed asset categories when the store is completed.
	Estimated Useful Lives
		Life
	Buildings		25 years
	Capital lease		20 years
	Leasehold improvements		15 years
	Furniture, fixtures and equipment		3 – 15 years
	We review long-lived assets for impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable.  We recognize impairment when the sum of undiscounted estimated future cash flows expected to result from the use of the asset is less than the carrying value of the asset.  We recognized an impairment of  $0.1 million in fiscal 2014 and $0.2 million in fiscal 2012 related to assets within land held for sale. There was no impairment of long-lived assets in fiscal 2013.  See Note 7 for additional information on property and equipment.
	(K)  Other Assets
	Goodwill and Intangible Assets.  Goodwill and other intangibles had a carrying value of $10.1 million as of February 28, 2014 and February 28, 2013.  We review goodwill and intangible assets for impairment annually or when circumstances indicate the carrying amount may not be recoverable.  No impairment of goodwill or intangible assets resulted from our annual impairment tests in fiscal 2014, fiscal 2013 or fiscal 2012.
	Restricted Cash on Deposit in Reserve Accounts.  The restricted cash on deposit in reserve accounts is for the benefit of holders of non-recourse notes payable, and these funds are not expected to be available to the company or its creditors.  In the event that the cash generated by the securitized receivables in a given period was insufficient to pay the interest, principal and other required payments, the balances on deposit in the reserve accounts would be used to pay those amounts.  Restricted cash on deposit in reserve accounts was $32.5 million as of February 28, 2014, and $41.3 million as of February 28, 2013.
	Restricted Investments.  Restricted investments includes money market securities primarily held to satisfy certain insurance program requirements, as well as mutual funds held in a rabbi trust established to fund informally our executive deferred compensation plan.  Restricted investments totaled $40.2 million as of February 28, 2014, and $35.0 million as of February 28, 2013.
	(L)  Finance Lease Obligations
	We generally account for sale-leaseback transactions as financings.  Accordingly, we record certain of the assets subject to these transactions on our consolidated balance sheets in property and equipment and the related sales proceeds as finance lease obligations.  Depreciation is recognized on the assets over 25 years.  Payments on the leases are recognized as interest expense and a reduction of the obligations.  See Notes 11 and 15 for additional information on finance lease obligations.
	(M)  Other Accrued Expenses
	As of February 28, 2014 and February 28, 2013, accrued expenses and other current liabilities included accrued compensation and benefits of $120.7 million and $103.4 million, respectively; loss reserves for general liability and workers’ compensation insurance of $29.7 million and $26.6 million, respectively; and the current portion of cancellation reserves. See Note 8 for additional information on cancellation reserves.
	(N)  Defined Benefit Plan Obligations
	The recognized funded status of defined benefit retirement plan obligations is included both in accrued expenses and other current liabilities and in other liabilities.  The current portion represents benefits expected to be paid from our benefit restoration plan over the next 12 months.  The defined benefit retirement plan obligations are determined by independent actuaries using a number of assumptions provided by CarMax.  Key assumptions used in measuring the plan obligations include the discount rate, rate of return on plan assets and mortality rate.  See Note 10 for additional information on our benefit plans.
	(O)  Insurance Liabilities
	Insurance liabilities are included in accrued expenses and other current liabilities.  We use a combination of insurance and self-insurance for a number of risks including workers’ compensation, general liability and employee-related health care costs, a portion of which is paid by associates.  Estimated insurance liabilities are determined by considering historical claims experience, demographic factors and other actuarial assumptions.
	(P)  Revenue Recognition
	We recognize revenue when the earnings process is complete, generally either at the time of sale to a customer or upon delivery to a customer.  As part of our customer service strategy, we guarantee the retail vehicles we sell with a 5‑day, money-back guarantee.  We record a reserve for estimated returns based on historical experience and trends.
	We sell ESPs and GAP on behalf of unrelated third parties to customers who purchase a vehicle.  The ESPs we offer on all used vehicles provide coverage up to 72 months (subject to mileage limitations), while GAP covers the customer for the term of their finance contract. We recognize commission revenue at the time of sale, net of a reserve for estimated customer cancellations.  Periodically, we may receive additional commissions based upon the level of underwriting profits of the third parties who administer the products.  These additional commissions are recognized as revenue when received.  The reserve for cancellations is evaluated for each product, and is based on forecasted forward cancellation curves utilizing historical experience, recent trends and credit mix of the customer base.  Our risk related to customer cancellations is limited to the commissions that we receive.  Cancellations fluctuate depending on the volume of ESP and GAP sales, customer financing default or prepayment rates, and shifts in customer behavior related to changes in the coverage or term of the product.  The current portion of estimated cancellation reserves is recognized as a component of other accrued expenses with the remaining amount recognized in other liabilities.  See Note 8 for additional information on cancellation reserves.
	Customers applying for financing who are not approved by CAF may be evaluated by other financial institutions.  Depending on the credit profile of the customer, third-party finance providers generally either pay us or are paid a fixed, pre-negotiated fee per contract.  We recognize these fees at the time of sale.
	We collect sales taxes and other taxes from customers on behalf of governmental authorities at the time of sale.  These taxes are accounted for on a net basis and are not included in net sales and operating revenues or cost of sales.
	(Q)  Cost of Sales
	Cost of sales includes the cost to acquire vehicles and the reconditioning and transportation costs associated with preparing the vehicles for resale.  It also includes payroll, fringe benefits and parts and repair costs associated with reconditioning and vehicle repair services.  The gross profit earned by our service department for used vehicle reconditioning service is a reduction of cost of sales.  We maintain a reserve to eliminate the internal profit on vehicles that have not been sold.
	(R)  Selling, General and Administrative Expenses
	Selling, general and administrative (“SG&A”) expenses primarily include compensation and benefits, other than payroll related to reconditioning and vehicle repair services; depreciation, rent and other occupancy costs; advertising; and IT expenses, insurance, bad debt, travel, preopening and relocation costs, charitable contributions and other administrative expenses.
	(S)  Advertising Expenses
	Advertising costs are expensed as incurred and substantially all are included in SG&A expenses.  Total advertising expenses were $114.6 million in fiscal 2014, $108.2 million in fiscal 2013 and $100.3 million in fiscal 2012.
	(T)  Store Opening Expenses
	Costs related to store openings, including preopening costs, are expensed as incurred and are included in SG&A expenses.
	(U)  Share-Based Compensation
	Share-based compensation represents the cost related to share-based awards granted to employees and non-employee directors.  We measure share-based compensation cost at the grant date, based on the estimated fair value of the award, and we recognize the cost on a straight-line basis (net of estimated forfeitures) over the grantee’s requisite service period, which is generally the vesting period of the award.  We estimate the fair value of stock options using a binomial valuation model.  Key assumptions used in estimating the fair value of options are dividend yield, expected volatility, risk-free interest rate and expected term.  The fair value of restricted stock is based on the volume-weighted average market value on the date of the grant.  The fair value of stock-settled restricted stock units is determined using a Monte-Carlo simulation based on the expected market price of our common stock on the vesting date and the expected number of converted common shares.  Cash-settled restricted stock units are liability awards with fair value measurement based on the market price of CarMax common stock as of the end of each reporting period.  Share-based compensation expense is recorded in either cost of sales, CAF income or SG&A expenses based on the recipients’ respective function.
We record deferred tax assets for awards that result in deductions on our income tax returns, based on the amount of compensation expense recognized and the statutory tax rate in the jurisdiction in which we will receive a deduction.  Differences between the deferred tax assets recognized for financial reporting purposes and the actual tax deduction reported on the income tax return are recorded in capital in excess of par value (if the tax deduction exceeds the deferred tax asset) or in the consolidated statements of earnings (if the deferred tax asset exceeds the tax deduction and no capital in excess of par value exists from previous awards).  See Note 12 for additional information on stock-based compensation.
(V)  Derivative Instruments and Hedging Activities
We enter into derivative instruments to manage exposures that arise from business activities that result in the future known receipt or payment of uncertain cash amounts, the values of which are impacted by interest rates.  We recognize the derivatives at fair value as either current assets or current liabilities on the consolidated balance sheets, and where applicable, such contracts covered by master netting agreements are reported net.  Gross positive fair values are netted with gross negative fair values by counterparty.  The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting.  We may enter into derivative contracts that are intended to economically hedge certain risks, even though hedge accounting may not apply or we do not elect to apply hedge accounting.  See Note 5 for additional information on derivative instruments and hedging activities.
(W)  Income Taxes
We file a consolidated federal income tax return for a majority of our subsidiaries.  Certain subsidiaries are required to file separate partnership or corporate federal income tax returns.  Deferred income taxes reflect the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and the amounts recognized for income tax purposes, measured by applying currently enacted tax laws.  A deferred tax asset is recognized if it is more likely than not that a benefit will be realized.  Changes in tax laws and tax rates are reflected in the income tax provision in the period in which the changes are enacted.
We recognize tax liabilities when, despite our belief that our tax return positions are supportable, we believe that certain positions may not be fully sustained upon review by tax authorities.  Benefits from tax positions are measured at the highest tax benefit that is greater than 50% likely of being realized upon settlement.  The current portion of these tax liabilities is included in accrued income taxes and any noncurrent portion is included in other liabilities.  To the extent that the final tax outcome of these matters is different from the amounts recorded, the differences impact income tax expense in the period in which the determination is made.  Interest and penalties related to income tax matters are included in SG&A expenses.  See Note 9 for additional information on income taxes.
(X)  Net Earnings Per Share
Basic net earnings per share is computed by dividing net earnings available for basic common shares by the weighted average number of shares of common stock outstanding.  Diluted net earnings per share is computed by dividing net earnings available for diluted common shares by the sum of the weighted average number of shares of common stock outstanding and dilutive potential common stock.  For periods with outstanding participating securities, diluted net earnings per share reflects the more dilutive of the “if-converted” treasury stock method or the two-class method.  For periods with no outstanding participating securities, diluted net earnings per share is calculated using the “if-converted” treasury stock method.  See Note 13 for additional information on net earnings per share.
(Y)  Recent Accounting Pronouncements
In December 2011, the Financial Accounting Standards Board (“FASB”) issued an accounting pronouncement related to offsetting of assets and liabilities on the balance sheet (FASB ASC Topic 210).  The amendments require additional disclosures related to offsetting either in accordance with U.S. GAAP or master netting arrangements.  In January 2013, an update was issued to clarify the scope applies to derivatives.  The provisions of this pronouncement and update are effective for fiscal years, and interim periods within those years, beginning after January 1, 2013.  We adopted this pronouncement for our fiscal year beginning March 1, 2013, and there was no effect on our consolidated financial statements.
In July 2012, the FASB issued an accounting pronouncement related to intangibles – goodwill and other (FASB ASC Topic 350), which permits companies to first consider qualitative factors as a basis for assessing impairment and determining the necessity of a detailed impairment test of indefinite-lived intangible assets.  The provisions of this pronouncement are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012.  We adopted this pronouncement for our fiscal year beginning March 1, 2013, and there was no effect on our consolidated financial statements.
In February 2013, the FASB issued an accounting pronouncement related to comprehensive income (FASB ASC Topic 220), requiring improved disclosures of reclassifications out of accumulated other comprehensive income.  The provisions of the pronouncement require an entity to report the amounts reclassified, in their entirety, out of accumulated other comprehensive income and the effect on the respective line items in net income.  For amounts not reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference the amounts to other related disclosures.  This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012.  We adopted this pronouncement for our fiscal year beginning March 1, 2013, and there was no effect on our consolidated financial statements. The required disclosures have been adopted in Note 14.
In February 2013, the FASB issued an accounting pronouncement related to liabilities (FASB ASC Topic 405).  The amendments provide guidance on the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements, including debt arrangements, other contractual obligations, and settled litigation and judicial rulings.  This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013.  We will adopt this pronouncement for our fiscal year beginning March 1, 2014.  We do not expect this pronouncement to have a material effect on our consolidated financial statements.
In July 2013, the FASB issued an accounting pronouncement related to derivatives and hedging (FASB ASC Topic 815), which allows the use of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a benchmark interest rate for hedge accounting purposes in addition to interest rates on direct Treasury obligations of the United States government and LIBOR.  In addition, the guidance removes the restriction on using different benchmark rates for similar hedges.  The pronouncement became effective on a prospective basis for qualifying new or designated hedging relationships entered into on or after July 17, 2013.  It did not have a material effect on our consolidated financial statements.
In July 2013, the FASB issued an accounting pronouncement related to income taxes (FASB ASC Topic 740), which provides guidance regarding the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar loss or a tax credit carryforward exists.  Under certain circumstances, unrecognized tax benefits should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward.  This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, with early adoption permitted.  We will adopt this pronouncement for our fiscal year beginning March 1, 2014.  We do not expect this pronouncement to have a material effect on our consolidated financial statements.

	3.CarMax Auto Finance
	CAF provides financing to qualified customers purchasing vehicles at CarMax.  CAF provides us the opportunity to capture additional sales, profits and cash flows while managing our reliance on third-party finance sources.  Management regularly analyzes CAF's operating results by assessing profitability, the performance of the auto loan receivables including trends in credit losses and delinquencies, and CAF direct expenses.  This information is used to assess CAF's performance and make operating decisions including resource allocation.  In addition, except for auto loan receivables, which are disclosed in Note 4, CAF assets are not separately reported nor do we allocate assets to CAF because such allocation would not be useful to management in making operating decisions.
	We typically use securitizations to fund loans originated by CAF, as discussed in Note 2(F).  CAF income primarily reflects the interest and fee income generated by the auto loan receivables less the interest expense associated with the debt issued to fund these receivables, a provision for estimated loan losses and direct CAF expenses.
	CAF income does not include any allocation of indirect costs.  We present this information on a direct basis to avoid making arbitrary decisions regarding the indirect benefits or costs that could be attributed to CAF.  Examples of indirect costs not allocated to CAF include retail store expenses and corporate expenses such as human resources, administrative services, marketing, information systems, accounting, legal, treasury and executive payroll.

	Auto loan receivables include amounts due from customers related to retail vehicle sales financed through CAF and are presented net of an allowance for estimated loan losses.  We use warehouse facilities to fund auto loan receivables originated by CAF until we elect to fund them through a term securitization or alternative funding arrangement.  The majority of the auto loan receivables serve as collateral for the related non-recourse notes payable of $7.25 billion as of February 28, 2014, and $5.86 billion as of February 28, 2013.  See Notes 2(F) and 11 for additional information on securitizations and non-recourse notes payable.

	Credit Quality.  When customers apply for financing, CAF’s proprietary scoring models rely on the customers’ credit history and certain application information to evaluate and rank their risk.  Credit histories are obtained from credit bureau reporting agencies and include information such as number, age, type of and payment history for prior or existing credit accounts.  The application information that is used includes income, collateral value and down payment.  The scoring models yield credit grades that represent the relative likelihood of repayment.  Customers assigned a grade of “A” are determined to have the highest probability of repayment, and customers assigned a lower grade are determined to have a lower probability of repayment.  For loans that are approved, the credit grade influences the terms of the agreement, such as the required loan-to-value ratio and interest rate.
	CAF uses a combination of the initial credit grades and historical performance to monitor the credit quality of the auto loan receivables on an ongoing basis.  We validate the accuracy of the scoring models periodically.  Loan performance is reviewed on a recurring basis to identify whether the assigned grades adequately reflect the customers’ likelihood of repayment.

Derivative Instruments And Hedging Activities	'
	5.Derivative Instruments and Hedging Activities
	Risk Management Objective of Using Derivatives.  We are exposed to certain risks arising from both our business operations and economic conditions, particularly with regard to future issuances of fixed-rate debt and existing and future issuances of floating-rate debt.  Primary exposures include LIBOR and other rates used as benchmarks in our securitizations.  We enter into derivative instruments to manage exposures that arise from business activities that result in the future known receipt or payment of uncertain cash amounts, the values of which are impacted by interest rates.  Our derivative instruments are used to manage differences in the amount of our known or expected cash receipts and our known or expected cash payments principally related to the funding of our auto loan receivables.
	We do not anticipate significant market risk from derivatives as they are predominantly used to match funding costs to the use of the funding.  However, disruptions in the credit or interest rate markets could impact the effectiveness of our hedging strategies.
	Credit risk is the exposure to nonperformance of another party to an agreement.  We mitigate credit risk by dealing with highly rated bank counterparties.
	Designated Cash Flow Hedges.  Our objectives in using interest rate derivatives are to add stability to CAF’s interest expense, to manage our exposure to interest rate movements and to better match funding costs to the interest received on the fixed-rate receivables being securitized.  To accomplish these objectives, we primarily use interest rate swaps that involve the receipt of variable amounts from a counterparty in exchange for our making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.  These interest rate swaps are designated as cash flow hedges of forecasted interest payments in anticipation of permanent funding in the term securitization market.
	For derivatives that are designated and qualify as cash flow hedges, the effective portion of changes in the fair value is initially recorded in accumulated other comprehensive loss (“AOCL”) and is subsequently reclassified into CAF income in the period that the hedged forecasted transaction affects earnings.  The ineffective portion of the change in fair value of the derivatives is recognized directly in CAF income.  Amounts reported in AOCL related to derivatives will be reclassified to CAF income as interest expense is incurred on our future issuances of fixed-rate debt.  During the next 12 months, we estimate that an additional $9.3 million will be reclassified as a decrease to CAF income.
	As of February 28, 2014 and 2013, we had interest rate swaps outstanding with a combined notional amount of $869.0 million and $750.0 million, respectively that were designated as cash flow hedges of interest rate risk.
	Non-designated Hedges.  Derivative instruments not designated as accounting hedges are not speculative.  These instruments are used to limit risk for investors in the warehouse facilities.  Changes in the fair value of derivatives not designated as accounting hedges are recorded directly in CAF income.
	As of February 28, 2014,  we had no derivatives or interest rate caps that were not designated as accounting hedges.  As of February 28, 2013, we had interest rate caps outstanding with offsetting (asset and liability) notional amounts of $615.5 million that were not designated as accounting hedges.

Fair Value Measurements [Abstract]	'
Fair Value Measurements	'
	6.Fair value measurements
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market or, if none exists, the most advantageous market, for the specific asset or liability at the measurement date (referred to as the “exit price”).  The fair value should be based on assumptions that market participants would use, including a consideration of nonperformance risk.
	We assess the inputs used to measure fair value using the three-tier hierarchy.  The hierarchy indicates the extent to which inputs used in measuring fair value are observable in the market.
	Level 1Inputs include unadjusted quoted prices in active markets for identical assets or liabilities that we can access at the measurement date.
	Level 2Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets in active markets, quoted prices from identical or similar assets in inactive markets and observable inputs such as interest rates and yield curves.
	Level 3Inputs that are significant to the measurement that are not observable in the market and include management's judgments about the assumptions market participants would use in pricing the asset or liability (including assumptions about risk).
	Our fair value processes include controls that are designed to ensure that fair values are appropriate.  Such controls include model validation, review of key model inputs, analysis of period-over-period fluctuations and reviews by senior management.
	Valuation Methodologies
	Money Market Securities.  Money market securities are cash equivalents, which are included in either cash and cash equivalents or other assets, and consist of highly liquid investments with original maturities of three months or less.  We use quoted market prices for identical assets to measure fair value.  Therefore, all money market securities are classified as Level 1.
	Mutual Fund Investments.  Mutual fund investments consist of publicly traded mutual funds that primarily include diversified investments in large-, mid- and small-cap domestic and international companies.  The investments, which are included in other assets, are held in a rabbi trust established to fund informally our executive deferred compensation plan.  We use quoted active market prices for identical assets to measure fair value.  Therefore, all mutual fund investments are classified as Level 1.
	Derivative Instruments.  The fair values of our derivative instruments are included in either other current assets or accounts payable.  As described in Note 5, as part of our risk management strategy, we utilize derivative instruments to manage differences in the amount of our known or expected cash receipts and our known or expected cash payments principally related to the funding of our auto loan receivables.  Our derivatives are not exchange-traded and are over-the-counter customized derivative instruments.  All of our derivative exposures are with highly rated bank counterparties.
	We measure derivative fair values assuming that the unit of account is an individual derivative instrument and that derivatives are sold or transferred on a stand-alone basis.  We estimate the fair value of our derivatives using quotes determined by the derivative counterparties and third-party valuation services.  Quotes from third-party valuation services and quotes received from bank counterparties project future cash flows and discount the future amounts to a present value using market-based expectations for interest rates and the contractual terms of the derivative instruments.  The models do not require significant judgment and model inputs can typically be observed in a liquid market; however, because the models include inputs other than quoted prices in active markets, all derivatives are classified as Level 2.
	Our derivative fair value measurements consider assumptions about counterparty and our own nonperformance risk.  We monitor counterparty and our own nonperformance risk and, in the event that we determine that a party is unlikely to perform under terms of the contract, we would adjust the derivative fair value to reflect the nonperformance risk.

Cancellation Reserves [Abstract]	'
Cancellation Reserves	'
	8. CANCELLATION RESERVES
	We recognize commission revenue for ESPs and GAP products at the time of sale, net of a reserve for estimated contract cancellations.  Cancellations of these services may result from early termination by the customer, or default or prepayment on the finance contract.  The reserve for cancellations is evaluated for each product, and is based on forecasted forward cancellation curves utilizing historical experience, recent trends and credit mix of the customer base.
	Cancellation Reserves
		As of February 28
	(In millions)		2014		2013
	Balance as of beginning of year	$	32.7	$	28.5
	Cancellations		-36.9		-27.5
	Provision for future cancellations		76.7		31.7
	Balance as of end of year	$	72.5	$	32.7
	Cancellations fluctuate depending on the volume of ESP and GAP sales, customer financing default or prepayment rates, and shifts in customer behavior related to changes in the coverage or term of the product.  The current portion of estimated cancellation reserves is recognized as a component of other accrued expenses with the remaining amount recognized in other liabilities.
	Correction of Error
	In the fourth quarter of fiscal 2014, the company reviewed the assumptions used in developing its cancellation reserves for ESP and GAP products and incorporated additional data into a more sophisticated model as part of our evaluation of the cancellation rates.  This additional data included changes in the product and administration of the product by the company and changes in the credit mix of the customer base.  The data was previously available, but had not been considered in our evaluation of the reserve balances.  Based on our evaluation using a more sophisticated model, we determined that this additional data should have been considered in our previous assessments of cancellation reserves.  We corrected this accounting error by increasing the cancellation reserves and reducing other sales and revenue.  Fiscal 2014 net earnings were reduced by $11.9 million (net of tax of $7.6 million), or $0.05 per share, pertaining to fiscal 2013 and fiscal 2012.  The out of period error was not material to fiscal 2014 or any previously reported interim or annual period.

	(A)  Retirement Benefit Plans
	Effective December 31, 2008, we froze both of our noncontributory defined benefit plans: our pension plan (the “pension plan”) and our unfunded, nonqualified plan (the “restoration plan”), which restores retirement benefits for certain associates who are affected by Internal Revenue Code limitations on benefits provided under the pension plan.  No additional benefits have accrued under these plans since that date.  In connection with benefits earned prior to December 31, 2008, we have a continuing obligation to fund the pension plan and will continue to recognize net periodic pension expense for both plans.  We use a fiscal year end measurement date for both the pension plan and the restoration plan.

	(3)Includes debt securities of U.S. and foreign governments, their agencies and corporations, and diverse investments in mortgage-backed securities and banks; approximately 90% of securities relate to U.S. entities and 10% of securities relate to non-U.S. entities as of February 28, 2014 (85% and 15%, respectively, as of February 28, 2013).
	(4)Includes pooled funds representing short-term instruments that include governments, their agencies and corporations and large-, mid- and small-cap companies primarily from the U.S. bank sector; nearly 100% of securities relate to U.S. entities as of February 28, 2014 (nearly 100%  as of February 28, 2013).
	Plan Assets.  Our pension plan assets are held in trust and management sets the investment policies and strategies.  Long-term strategic investment objectives include asset preservation and appropriately balancing risk and return.  We oversee the investment allocation process, which includes selecting investment managers, setting long-term strategic targets and monitoring asset allocations and performance.  Target allocations for plan assets are guidelines, not limitations, and occasionally plan fiduciaries may approve allocations above or below the targets.  We target allocating 75% of plan assets to equity and equity-related instruments and 25% to fixed income securities.  Equity securities are currently composed of mutual funds that include highly diversified investments in large-, mid- and small-cap companies located in the United States and internationally.  The fixed income securities are currently composed of mutual funds that include investments in debt securities, mortgage-backed securities, corporate bonds and other debt obligations primarily in the United States.  We do not expect any plan assets to be returned to us during fiscal 2015.  Plan assets also include collective funds, which are public investment vehicles with the underlying assets representing high quality, short-term instruments that include securities of governments, their agencies and corporations and large, mid, and small cap companies located in the United States and internationally.
	The fair values of the plan’s assets are provided by the plan’s trustee and the investment managers.  Within the fair value hierarchy (see Note 6), the mutual funds are classified as Level 1 as quoted active market prices for identical assets are used to measure fair value.  The collective funds are public investment vehicles valued using a net asset value (“NAV”) provided by the plan’s trustee as a practical expedient for measuring the fair value.  The NAV is based on the underlying net assets owned by the fund divided by the number of shares outstanding.  The NAV’s unit price is quoted on a private market that was not active.  However, the NAV is based on the fair value of the underlying securities within the fund, which were traded on an active market and valued at the closing price reported on the active market on which those individual securities are traded.  The collective funds may be liquidated with minimal restrictions and are classified as Level 2.
	Funding Policy.  For the pension plan, we contribute amounts sufficient to meet minimum funding requirements as set forth in the employee benefit and tax laws, plus any additional amounts as we may determine to be appropriate.  We expect to contribute $4.2 million to the pension plan in fiscal 2015.  For the non-funded restoration plan, we contribute an amount equal to the benefit payments.

Expected rate of return on plan assets	7.75	%		7.75	%		7.75	%		―			―			―
(1)For the restoration plan, the discount rate presented is applied to the pre-2004 annuity amounts.  A rate of 4.50% is assumed for post-2004 lump sum amounts paid from the plan for fiscal 2014 and fiscal 2013.  For fiscal 2012 and prior years, a rate of 5.00% was assumed for post-2004 lump sum amounts paid from the plan.
Assumptions.  Underlying both the calculation of the PBO and the net pension expense are actuarial calculations of each plan’s liability.  These calculations use participant-specific information such as salary, age and years of service, as well as certain assumptions, the most significant being the discount rate, rate of return on plan assets and mortality rate.  We evaluate these assumptions at least once a year and make changes as necessary.
The discount rate used for retirement benefit plan accounting reflects the yields available on high-quality, fixed income debt instruments.  For our plans, we review high quality corporate bond indices in addition to a hypothetical portfolio of corporate bonds with maturities that approximate the expected timing of the anticipated benefit payments.
To determine the expected long-term return on plan assets, we consider the current and anticipated asset allocations, as well as historical and estimated returns on various categories of plan assets.  We apply the estimated rate of return to a market-related value of assets, which reduces the underlying variability in the asset values.  The use of expected long-term rates of return on pension plan assets could result in recognized asset returns that are greater or less than the actual returns of those pension plan assets in any given year.  Over time, however, the expected long-term returns are anticipated to approximate the actual long-term returns, and therefore, result in a pattern of income and expense recognition that more closely matches the pattern of the services provided by the employees.  Differences between actual and expected returns, which are a component of unrecognized actuarial gains/losses, are recognized over the average life expectancy of all plan participants.
Given the frozen status of the pension and benefit restoration plans, the rate of compensation increases is not applicable for periods subsequent to December 31, 2008.  Mortality rate assumptions are based on the life expectancy of the population and were updated in fiscal 2011 to account for increases in life expectancy.
(B)  Retirement Savings 401(k) Plan
We sponsor a 401(k) plan for all associates meeting certain eligibility criteria.  In conjunction with the pension plan curtailments, enhancements were made to the 401(k) plan effective January 1, 2009.  The enhancements increased the maximum salary contribution for eligible associates and increased our matching contribution.  Additionally, an annual company-funded contribution regardless of associate participation was implemented, as well as an additional company-funded contribution to those associates meeting certain age and service requirements.  The total cost for company contributions was $25.0 million in fiscal 2014, $23.1 million in fiscal 2013 and $20.9 million in fiscal 2012.
(C)  Retirement Restoration Plan
Effective January 1, 2009, we replaced the frozen restoration plan with a new non-qualified retirement plan for certain senior executives who are affected by Internal Revenue Code limitations on benefits provided under the Retirement Savings 401(k) Plan.  Under this plan, these associates may continue to defer portions of their compensation for retirement savings.  We match the associates’ contributions at the same rate provided under the 401(k) plan, and also provide the annual company-funded contribution made regardless of associate participation, as well as the additional company-funded contribution to the associates meeting the same age and service requirements.  This plan is unfunded with lump sum payments to be made upon the associate’s retirement.  The total cost for this plan was $1.1 million in fiscal 2014, $0.4 million in fiscal 2013 and $0.5 million in fiscal 2012.
(D)  Executive Deferred Compensation Plan
Effective January 1, 2011, we established an unfunded nonqualified deferred compensation plan to permit certain eligible key associates to defer receipt of a portion of their compensation to a future date.  This plan also includes a restorative company contribution designed to compensate the plan participants for any loss of company contributions under the Retirement Savings 401(k) Plan and the Retirement Restoration Plan due to a reduction in their eligible compensation resulting from deferrals into the Executive Deferred Compensation Plan.  The total cost for this plan was $0.6 million in fiscal 2014, $0.4 million in fiscal 2013 and was not material in fiscal 2012.

	Revolving Credit Facility.  Our $700 million unsecured revolving credit facility (the “credit facility”) expires in August 2016.  Borrowings under the credit facility are available for working capital and general corporate purposes.  Borrowings accrue interest at variable rates based on LIBOR, the federal funds rate, or the prime rate, depending on the type of borrowing, and we pay a commitment fee on the unused portions of the available funds.  As of February 28, 2014, the remaining capacity of the credit facility was fully available to us.
	The weighted average interest rate on outstanding short-term and long-term debt was 1.5% in fiscal 2014 and 1.8% in fiscal 2013 and 1.6% in fiscal 2012.
	We capitalize interest in connection with the construction of certain facilities.  There was no capitalized interest in fiscal 2014, fiscal 2013 or fiscal 2012.
	Finance and Capital Lease Obligations.  Finance and capital lease obligations relate primarily to superstores subject to sale-leaseback transactions that did not qualify for sale accounting, and therefore, are accounted for as financings.  The leases were structured at varying interest rates and generally have initial lease terms ranging from 15 to 20 years with payments made monthly.  Payments on the leases are recognized as interest expense and a reduction of the obligations.  We have not entered into any sale-leaseback transactions since fiscal 2009.  See Note 15 for information on future minimum lease obligations.
	Non-Recourse Notes Payable.  The non-recourse notes payable relate to auto loan receivables funded through term securitizations and our warehouse facilities.  The timing of principal payments on the non-recourse notes payable is based on principal collections, net of losses, on the securitized auto loan receivables.  The current portion of non-recourse notes payable represents principal payments that are due to be distributed in the following period.
	As of February 28, 2014, $6.37 billion of non-recourse notes payable was outstanding related to term securitizations.  These notes payable accrue interest at fixed rates and have scheduled maturities through August 2020, but may mature earlier or later, depending upon the repayment rate of the underlying auto loan receivables.
	As of February 28, 2014, $879.0 million of non-recourse notes payable was outstanding related to our warehouse facilities.  The combined warehouse facility limit is $1.8 billion, and unused warehouse capacity totaled $921.0 million.  During the third quarter of fiscal 2014, we increased the limit of our $900 million warehouse facility that was scheduled to expire in February 2014 to $1 billion, and during the fourth quarter of fiscal 2014, we renewed the facility for an additional 364 day term. Of the combined warehouse facility limit, $800 million will expire in August 2014 and $1 billion will expire in February 2015.  The notes payable outstanding related to our warehouse facilities do not have scheduled maturities, instead the principal payments depend upon the repayment rate of the underlying auto loan receivables.  The return requirements of investors could fluctuate significantly depending on market conditions.  Therefore, at renewal, the cost, structure and capacity of the facilities could change.  These changes could have a significant impact on our funding costs.
	See Notes 2(F) and 4 for additional information on the related securitized auto loan receivables.
	Financial Covenants. The credit facility agreement contains representations and warranties, conditions and covenants.  We must also meet financial covenants in conjunction with certain of the sale-leaseback transactions.  Our securitization agreements contain representations and warranties, financial covenants and performance triggers.  As of February 28, 2014, we were in compliance with all financial covenants and our securitized receivables were in compliance with the related performance triggers.

	12.Stock and Stock-Based Incentive Plans
	(A) Preferred Stock
	Under the terms of our Articles of Incorporation, the board of directors may determine the rights, preferences and terms of our authorized but unissued shares of preferred stock.  We have authorized 20,000,000 shares of preferred stock, $20 par value.  In 2002, we created a series of preferred stock designated as “Cumulative Participating Preferred Stock, Series A” in connection with the shareholder rights plan adopted by the company.  The number of shares constituting such series is 300,000.  The shareholders rights plan expired in 2012, and no shares of such Series A Cumulative Participating Preferred Stock or any other preferred stock are currently outstanding.
	(B) Share Repurchase Program
	In fiscal 2013, our board of directors authorized the repurchase of up to $800 million of our common stock.  Of the total authorized, $300 million was scheduled to expire on December 31, 2013, with the remaining $500 million scheduled to expire on December 31, 2014.  Purchases may be made in the open market or privately negotiated transactions at management’s discretion and the timing and amount of repurchases are determined based on share price, market conditions, legal requirements and other factors.  Shares repurchased are deemed authorized but unissued shares of common stock.
	During fiscal 2014, we repurchased 6,859,518 shares of common stock at an average purchase price of $44.61 per share.  During fiscal 2013, we repurchased 5,762,000 shares of common stock at an average purchase price of $36.77 per share.  As of February 28, 2014,  $282.1 million was available for repurchase under the authorizations.  Subsequent to the end of fiscal 2014, in March 2014, our board of directors authorized the repurchase of up to an additional $1 billion of our common stock through December 31, 2015.
	(C) Stock Incentive Plans
	We maintain long-term incentive plans for management, key employees and the nonemployee members of our board of directors.  The plans allow for the granting of equity-based compensation awards, including nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock awards, stock- and cash-settled restricted stock units, stock grants or a combination of awards.  To date, we have not awarded any incentive stock options.
	As of February 28, 2014, a total of 50,200,000 shares of our common stock had been authorized to be issued under the long-term incentive plans.  The number of unissued common shares reserved for future grants under the long-term incentive plans was 10,637,303 as of that date.
	Prior to fiscal 2007, the majority of associates who received share-based compensation awards primarily received nonqualified stock options.  From fiscal 2007 through fiscal 2009, these associates primarily received restricted stock instead of stock options, and beginning in fiscal 2010, these associates primarily receive cash-settled restricted stock units instead of restricted stock awards.  Senior management and other key associates receive awards of nonqualified stock options and, starting in fiscal 2010, stock-settled restricted stock units.  Nonemployee directors receive awards of nonqualified stock options and stock grants.
	Nonqualified Stock Options.  Nonqualified stock options are awards that allow the recipient to purchase shares of our common stock at a fixed price.  Stock options are granted at an exercise price equal to the fair market value of our common stock on the grant date.  The stock options generally vest annually in equal amounts over periods of one to four years.  These options are subject to forfeiture and expire no later than ten years after the date of the grant.
	Cash-Settled Restricted Stock Units.  Also referred to as restricted stock units, or RSUs, these are awards that entitle the holder to a cash payment equal to the fair market value of a share of our common stock for each unit granted.  Conversion generally occurs at the end of a three-year vesting period.  However, the cash payment per RSU will not be greater than 200% or less than 75% of the fair market value of a share of our common stock on the grant date.  RSUs are liability awards that are subject to forfeiture and do not have voting rights.
	Stock-Settled Restricted Stock Units.  Also referred to as market stock units, or MSUs, these are awards to eligible key associates that are converted into between zero and two shares of common stock for each unit granted.  Conversion generally occurs at the end of a three-year vesting period.  The conversion ratio is calculated by dividing the average closing price of our stock during the final forty trading days of the three-year vesting period by our stock price on the grant date, with the resulting quotient capped at two.  This quotient is then multiplied by the number of MSUs granted to yield the number of shares awarded.  MSUs are subject to forfeiture and do not have voting rights.
	Restricted Stock.  Restricted stock awards are awards of our common stock that are subject to specified restrictions and a risk of forfeiture.  The restrictions typically lapse three years from the grant date.  Participants holding restricted stock are entitled to vote on matters submitted to holders of our common stock for a vote.  No restricted stock awards have been granted since fiscal 2009, and no awards were outstanding during fiscal 2014 and 2013.  We realized related tax benefits of $10.9 million in fiscal 2012 from the vesting of restricted stock.

	Share-based compensation expense, before income taxes		$	67,670		$	63,174	$	49,104
	We recognize compensation expense for stock options,  MSUs and restricted stock on a straight-line basis (net of estimated forfeitures) over the requisite service period, which is generally the vesting period of the award.  The variable expense associated with RSUs is recognized over their vesting period (net of estimated forfeitures) and is calculated based on the volume-weighted average price of our common stock on the last trading day of each reporting period.  The total costs for matching contributions for our employee stock purchase plan are included in share-based compensation expense.  There were no capitalized share-based compensation costs as of the end of fiscal 2014, fiscal 2013 or fiscal 2012.

	For stock options, the fair value of each award is estimated as of the date of grant using a binomial valuation model.  In computing the value of the option, the binomial model considers characteristics of fair-value option pricing that are not available for consideration under a closed-form valuation model (for example, the Black-Scholes model), such as the contractual term of the option, the probability that the option will be exercised prior to the end of its contractual life and the probability of termination or retirement of the option holder.  For this reason, we believe that the binomial model provides a fair value that is more representative of actual experience and future expected experience than the value calculated using a closed-form model.  Estimates of fair value are not intended to predict actual future events or the value ultimately realized by the recipients of share-based awards.
	The weighted average fair value per share at the date of grant for options granted was $15.59 in fiscal 2014, $12.67 in fiscal 2013 and $13.80 in fiscal 2012.  The unrecognized compensation costs related to nonvested options totaled $32.6 million as of February 28, 2014.  These costs are expected to be recognized on a straight-line basis over a weighted average period of 2.0 years.

We granted 237,660 MSUs in fiscal 2014,  348,551 MSUs in fiscal 2013 and 299,102 MSUs in fiscal 2012.  The weighted average fair value per MSU at the date of grant was $52.02 in fiscal 2014, $40.33 in fiscal 2013 and $45.48 in fiscal 2012.  The fair values were determined using a Monte-Carlo simulation and were based on the expected market price of our common stock on the vesting date and the expected number of converted common shares.  We realized related tax benefits of $7.9 million during fiscal 2014, from the vesting of market stock units.  The unrecognized compensation costs related to nonvested MSUs totaled $13.4 million as of February 28, 2014.  These costs are expected to be recognized on a straight-line basis over a weighted average period of 1.0 years.
(E) Employee Stock Purchase Plan
We sponsor an employee stock purchase plan for all associates meeting certain eligibility criteria.  Associate contributions are limited to 10% of eligible compensation, up to a maximum of $7,500 per year.  For each $1.00 contributed to the plan by associates, we match $0.15.  We have authorized up to 8,000,000 shares of common stock for the employee stock purchase plan.  Shares are acquired through open-market purchases.
As of February 28, 2014, a total of 3,724,673 shares remained available under the plan.  Shares purchased in the open market on behalf of associates totaled 188,797 during fiscal 2014,  251,667 during fiscal 2013 and 260,927 during fiscal 2012.  The average price per share for purchases under the plan was $47.35 in fiscal 2014, $32.05 in fiscal 2013 and $30.02 in fiscal 2012.  The total costs for matching contributions are included in share-based compensation expense.

	Nonvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and should be included in the computation of net earnings per share pursuant to the two-class method as discussed in Note 2(X).  Our restricted stock awards are considered participating securities because they contain nonforfeitable rights to dividends and are included in the computation of net earnings per share pursuant to the two-class method.  Nonvested MSUs do not receive nonforfeitable dividend equivalent rights, and therefore, are not considered participating securities.  RSUs are nonparticipating, non-equity instruments, and therefore, are excluded from net earnings per share calculations.  There were no outstanding participating securities during fiscal 2014 and 2013.

	15.Lease Commitments
	Our leases primarily consist of land or land and building leases related to CarMax superstore locations.  Our lease obligations are based upon contractual minimum rates.  Most leases provide that we pay taxes, maintenance, insurance and operating expenses applicable to the premises.  The initial term of most real property leases will expire within the next 20 years; however, most of the leases have options providing for renewal periods of 5 to 20 years at terms similar to the initial terms.  For finance and capital leases, a portion of the periodic lease payments is recognized as interest expense and the remainder reduces the obligations.  For operating leases, rent is recognized on a straight-line basis over the lease term, including scheduled rent increases and rent holidays.  Rent expense for all operating leases was $43.6 million in fiscal 2014, $42.8 million in fiscal 2013 and $42.3 million in fiscal 2012.  See Note 11 for additional information on finance and capital lease obligations.

	(A) Litigation
	On April 2, 2008, Mr. John Fowler filed a putative class action lawsuit against CarMax Auto Superstores California, LLC and CarMax Auto Superstores West Coast, Inc. in the Superior Court of California, County of Los Angeles.  Subsequently, two other lawsuits, Leena Areso et al. v. CarMax Auto Superstores California, LLC and Justin Weaver v. CarMax Auto Superstores California, LLC, were consolidated as part of the Fowler case.  The allegations in the consolidated case involved: (1) failure to provide meal and rest breaks or compensation in lieu thereof; (2) failure to pay wages of terminated or resigned employees related to meal and rest breaks and overtime; (3) failure to pay overtime; (4) failure to comply with itemized employee wage statement provisions; (5) unfair competition; and (6) California’s Labor Code Private Attorney General Act.  The putative class consisted of sales consultants, sales managers, and other hourly employees who worked for the company in California from April 2, 2004, to the present.  On May 12, 2009, the court dismissed all of the class claims with respect to the sales manager putative class.  On June 16, 2009, the court dismissed all claims related to the failure to comply with the itemized employee wage statement provisions.  The court also granted CarMax's motion for summary adjudication with regard to CarMax's alleged failure to pay overtime to the sales consultant putative class.  The plaintiffs appealed the court's ruling regarding the sales consultant overtime claim.  On May 20, 2011, the California Court of Appeal affirmed the ruling in favor of CarMax.  The plaintiffs filed a Petition of Review with the California Supreme Court, which was denied.  As a result, the plaintiffs’ overtime claims are no longer a part of the lawsuit.
	The claims currently remaining in the lawsuit regarding the sales consultant putative class are: (1) failure to provide meal and rest breaks or compensation in lieu thereof; (2) failure to pay wages of terminated or resigned employees related to meal and rest breaks; (3) unfair competition; and (4) California’s Labor Code Private Attorney General Act.  On June 16, 2009, the court entered a stay of these claims pending the outcome of a California Supreme Court case involving unrelated third parties but related legal issues.  Subsequently, CarMax moved to lift the stay and compel the plaintiffs’ remaining claims into arbitration on an individual basis, which the court granted on November 21, 2011.  The plaintiffs appealed the court’s ruling to the California Court of Appeal.  On March 26, 2013, the California Court of Appeal reversed the trial court’s order granting CarMax’s motion to compel arbitration.  On October 8, 2013, CarMax filed a petition for a writ of certiorari seeking review in the United States Supreme Court.  On February 24, 2014, the United States Supreme Court granted CarMax's petition for certiorari, vacated the California Court of Appeal decision and remanded the case to the California Court of Appeal for further consideration. The Fowler lawsuit seeks compensatory and special damages, wages, interest, civil and statutory penalties, restitution, injunctive relief and the recovery of attorneys’ fees.  We are unable to make a reasonable estimate of the amount or range of loss that could result from an unfavorable outcome in these matters.
	We are involved in various other legal proceedings in the normal course of business.  Based upon our evaluation of information currently available, we believe that the ultimate resolution of any such proceedings will not have a material adverse effect, either individually or in the aggregate, on our financial condition, results of operations or cash flows.
	(B) Gain Contingency
	The Company is a class member in a consolidated and settled class action lawsuit (In Re Toyota Motor Corp. Unintended Acceleration Marketing, Sales Practices, and Products Liability Litig., Case No. 10-2151 (C.D. Cal.), consolidated as of April 9, 2010) against Toyota Motor Corp. and Toyota Motor Sales, USA, Inc. (collectively, “Toyota”) related to the economic loss associated with certain Toyota vehicles equipped with electronic throttle controls systems and the potential unintended acceleration of these vehicles.  On April 3, 2014, the claims administrator in this matter provided notice to the Company that the Company may recover approximately $20 million (net of attorney’s fees and expenses) as its share of the settlement proceeds in the third calendar quarter of 2014.  The estimated recovery: (1) may be reduced to the extent that the total claims made exceed the settlement pool; (2) is subject to final approval of supporting documentation; and (3) remains subject to the entry of a final approval order from the district court judge.  We will recognize these proceeds when funds are received from the claims administrator.
	(C) Other Matters
	In accordance with the terms of real estate lease agreements, we generally agree to indemnify the lessor from certain liabilities arising as a result of the use of the leased premises, including environmental liabilities and repairs to leased property upon termination of the lease.  Additionally, in accordance with the terms of agreements entered into for the sale of properties, we generally agree to indemnify the buyer from certain liabilities and costs arising subsequent to the date of the sale, including environmental liabilities and liabilities resulting from the breach of representations or warranties made in accordance with the agreements.  We do not have any known material environmental commitments, contingencies or other indemnification issues arising from these arrangements.
	As part of our customer service strategy, we guarantee the used vehicles we retail with at least a 30-day limited warranty.  A vehicle in need of repair within this period will be repaired free of charge.  As a result, each vehicle sold has an implied liability associated with it.  Accordingly, based on historical trends, we record a provision for estimated future repairs during the guarantee period for each vehicle sold.  The liability for this guarantee was $5.7 million as of February 28, 2014, and $4.6 million as of February 29, 2013, and is included in accrued expenses and other current liabilities.

Summary Of Significant Accounting Policies (Policy)	12 Months Ended
	Feb. 28, 2014
Summary Of Significant Accounting Policies [Abstract]	'
Basis Of Presentation And Use Of Estimates	'
	(A)  Basis of Presentation and Use of Estimates
	The consolidated financial statements include the accounts of CarMax and our wholly owned subsidiaries.  All significant intercompany balances and transactions have been eliminated in consolidation.  The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities.  Actual results could differ from those estimates.  Certain prior year amounts have been reclassified to conform to the current year’s presentation.  Amounts and percentages may not total due to rounding.
Cash And Cash Equivalents	'
	(B)  Cash and Cash Equivalents
	Cash equivalents of $607.0 million as of February 28, 2014, and $430.3 million as of February 28, 2013, consisted of highly liquid investments with original maturities of three months or less.
Restricted Cash From Collections On Auto Loan Receivables	'
	(C)  Restricted Cash from Collections on Auto Loan Receivables
	Cash accounts totaling $259.3 million as of February 28, 2014, and $224.3 million as of February 28, 2013, consisted of collections of principal and interest payments on securitized auto loan receivables that are restricted for payment to the securitization investors pursuant to the applicable securitization agreements.
Marketable Securities	'
	(D)  Marketable Securities
	The Company classifies all marketable securities as available-for-sale.  These securities consisted exclusively of variable-rate demand notes reported at fair value with unrealized gains and losses, net of taxes, excluded from net income and shown separately as a component of accumulated other comprehensive loss within shareholders' equity.  There were no marketable securities available-for-sale as of February 28, 2014 and 2013.
	Proceeds from the sales of marketable securities available-for-sale were $0.5 million and $30.3 million in fiscal 2014 and 2013, respectively.  There were no related gains or losses during fiscal 2014 and fiscal 2013.
Accounts Receivable, Net	'
	(E)  Accounts Receivable, Net
	Accounts receivable, net of an allowance for doubtful accounts, includes certain amounts due from third-party finance providers and customers and other miscellaneous receivables.  The allowance for doubtful accounts is estimated based on historical experience and trends.
Securitizations	'
	(F)  Securitizations
	We maintain a revolving securitization program composed of two warehouse facilities (“warehouse facilities”) that we use to fund auto loan receivables originated by CAF until we elect to fund them through a term securitization or alternative funding arrangement.  We sell the auto loan receivables to a wholly owned, bankruptcy-remote, special purpose entity that transfers an undivided percentage ownership interest in the receivables, but not the receivables themselves, to entities formed by third-party investors.  These entities issue asset-backed commercial paper or utilize other funding sources supported by the transferred receivables, and the proceeds are used to finance the securitized receivables.
	We typically use term securitizations to provide long-term funding for most of the auto loan receivables initially securitized through the warehouse facilities.  In these transactions, a pool of auto loan receivables is sold to a bankruptcy-remote, special purpose entity that, in turn, transfers the receivables to a special purpose securitization trust.  The securitization trust issues asset-backed securities, secured or otherwise supported by the transferred receivables, and the proceeds from the sale of the asset-backed securities are used to finance the securitized receivables.
	We are required to evaluate term securitization trusts for consolidation.  In our capacity as servicer, we have the power to direct the activities of the trusts that most significantly impact the economic performance of the trusts.  In addition, we have the obligation to absorb losses (subject to limitations) and the rights to receive any returns of the trusts, which could be significant.  Accordingly, we are the primary beneficiary of the trusts and are required to consolidate them.
	We recognize transfers of auto loan receivables into the warehouse facilities and term securitizations (“securitization vehicles”) as secured borrowings, which result in recording the auto loan receivables and the related non-recourse notes payable to the investors on our consolidated balance sheets.
	The securitized receivables can only be used as collateral to settle obligations of the securitization vehicles.  The securitization vehicles and investors have no recourse to our assets beyond the securitized receivables, the amounts on deposit in reserve accounts and the restricted cash from collections on auto loan receivables.  We have not provided financial or other support to the securitization vehicles that was not previously contractually required, and there are no additional arrangements, guarantees or other commitments that could require us to provide financial support to the securitization vehicles.
	See Notes 4 and 11 for additional information on auto loan receivables and non-recourse notes payable.
Fair Value Of Financial Instruments	'
	(G)  Fair Value of Financial Instruments
	Due to the short-term nature and/or variable rates associated with these financial instruments, the carrying value of our cash and cash equivalents, restricted cash, accounts receivable, money market securities, accounts payable, short-term debt and long-term debt approximates fair value.  Our derivative instruments and mutual funds are recorded at fair value.  Auto loan receivables are presented net of an allowance for estimated loan losses.  See Note 6 for additional information on fair value measurements.
Inventory	'
	(H)  Inventory
	Inventory is primarily comprised of vehicles held for sale or currently undergoing reconditioning and is stated at the lower of cost or market.  Vehicle inventory cost is determined by specific identification.  Parts and labor used to recondition vehicles, as well as transportation and other incremental expenses associated with acquiring and reconditioning vehicles, are included in inventory.
Auto Loan Receivables, Net	'
	(I)  Auto Loan Receivables, Net
	Auto loan receivables include amounts due from customers related to retail vehicle sales financed through CAF.  The receivables are presented net of an allowance for estimated loan losses.  The allowance for loan losses represents an estimate of the amount of net losses inherent in our portfolio of managed receivables as of the applicable reporting date and anticipated to occur during the following 12 months.  The allowance is primarily based on the credit quality of the underlying receivables, historical loss trends and forecasted forward loss curves.  We also take into account recent trends in delinquencies and losses, recovery rates and the economic environment.  The provision for loan losses is the periodic expense of maintaining an adequate allowance.
	An account is considered delinquent when the related customer fails to make a substantial portion of a scheduled payment on or before the due date.  In general, accounts are charged-off on the last business day of the month during which the earliest of the following occurs:  the receivable is 120 days or more delinquent as of the last business day of the month, the related vehicle is repossessed and liquidated, or the receivable is otherwise deemed uncollectible.  For purposes of determining impairment, auto loans are evaluated collectively, as they represent a large group of smaller-balance homogeneous loans, and therefore, are not individually evaluated for impairment.  See Note 4 for additional information on auto loan receivables.
	Interest income and expenses related to auto loans are included in CAF income.  Interest income on auto loan receivables is recognized when earned based on contractual loan terms.  All loans continue to accrue interest until repayment or charge-off.  Direct costs associated with loan originations are not considered material, and thus, are expensed as incurred.  See Note 3 for additional information on CAF income.
Property And Equipment	'
	(J)  Property and Equipment
	Property and equipment is stated at cost less accumulated depreciation and amortization.  Depreciation and amortization are calculated using the straight-line method over the shorter of the asset’s estimated useful life or the lease term, if applicable.  Property held under capital lease is stated at the lesser of the present value of the future minimum lease payments at the inception of the lease or fair value.  Amortization of capital lease assets is computed on a straight-line basis over the shorter of the initial lease term or the estimated useful life of the asset and is included in depreciation expense.  Costs incurred during new store construction are capitalized as construction-in-progress and reclassified to the appropriate fixed asset categories when the store is completed.
	Estimated Useful Lives
		Life
	Buildings		25 years
	Capital lease		20 years
	Leasehold improvements		15 years
	Furniture, fixtures and equipment		3 – 15 years
	We review long-lived assets for impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable.  We recognize impairment when the sum of undiscounted estimated future cash flows expected to result from the use of the asset is less than the carrying value of the asset.  We recognized an impairment of  $0.1 million in fiscal 2014 and $0.2 million in fiscal 2012 related to assets within land held for sale. There was no impairment of long-lived assets in fiscal 2013.  See Note 7 for additional information on property and equipment.
Goodwill and Intangible Assets	'
	Goodwill and Intangible Assets.  Goodwill and other intangibles had a carrying value of $10.1 million as of February 28, 2014 and February 28, 2013.  We review goodwill and intangible assets for impairment annually or when circumstances indicate the carrying amount may not be recoverable.  No impairment of goodwill or intangible assets resulted from our annual impairment tests in fiscal 2014, fiscal 2013 or fiscal 2012.
Other Assets Restricted	'
	Restricted Cash on Deposit in Reserve Accounts.  The restricted cash on deposit in reserve accounts is for the benefit of holders of non-recourse notes payable, and these funds are not expected to be available to the company or its creditors.  In the event that the cash generated by the securitized receivables in a given period was insufficient to pay the interest, principal and other required payments, the balances on deposit in the reserve accounts would be used to pay those amounts.  Restricted cash on deposit in reserve accounts was $32.5 million as of February 28, 2014, and $41.3 million as of February 28, 2013.
	Restricted Investments.  Restricted investments includes money market securities primarily held to satisfy certain insurance program requirements, as well as mutual funds held in a rabbi trust established to fund informally our executive deferred compensation plan.  Restricted investments totaled $40.2 million as of February 28, 2014, and $35.0 million as of February 28, 2013.
Finance Lease Obligations	'
	(L)  Finance Lease Obligations
	We generally account for sale-leaseback transactions as financings.  Accordingly, we record certain of the assets subject to these transactions on our consolidated balance sheets in property and equipment and the related sales proceeds as finance lease obligations.  Depreciation is recognized on the assets over 25 years.  Payments on the leases are recognized as interest expense and a reduction of the obligations.  See Notes 11 and 15 for additional information on finance lease obligations.
Other Accrued Expenses	'
	(M)  Other Accrued Expenses
	As of February 28, 2014 and February 28, 2013, accrued expenses and other current liabilities included accrued compensation and benefits of $120.7 million and $103.4 million, respectively; loss reserves for general liability and workers’ compensation insurance of $29.7 million and $26.6 million, respectively; and the current portion of cancellation reserves. See Note 8 for additional information on cancellation reserves.
Defined Benefit Plan Obligations	'
	(N)  Defined Benefit Plan Obligations
	The recognized funded status of defined benefit retirement plan obligations is included both in accrued expenses and other current liabilities and in other liabilities.  The current portion represents benefits expected to be paid from our benefit restoration plan over the next 12 months.  The defined benefit retirement plan obligations are determined by independent actuaries using a number of assumptions provided by CarMax.  Key assumptions used in measuring the plan obligations include the discount rate, rate of return on plan assets and mortality rate.  See Note 10 for additional information on our benefit plans.
Insurance Liabilities	'
	(O)  Insurance Liabilities
	Insurance liabilities are included in accrued expenses and other current liabilities.  We use a combination of insurance and self-insurance for a number of risks including workers’ compensation, general liability and employee-related health care costs, a portion of which is paid by associates.  Estimated insurance liabilities are determined by considering historical claims experience, demographic factors and other actuarial assumptions.
Revenue Recognition	'
	(P)  Revenue Recognition
	We recognize revenue when the earnings process is complete, generally either at the time of sale to a customer or upon delivery to a customer.  As part of our customer service strategy, we guarantee the retail vehicles we sell with a 5‑day, money-back guarantee.  We record a reserve for estimated returns based on historical experience and trends.
	We sell ESPs and GAP on behalf of unrelated third parties to customers who purchase a vehicle.  The ESPs we offer on all used vehicles provide coverage up to 72 months (subject to mileage limitations), while GAP covers the customer for the term of their finance contract. We recognize commission revenue at the time of sale, net of a reserve for estimated customer cancellations.  Periodically, we may receive additional commissions based upon the level of underwriting profits of the third parties who administer the products.  These additional commissions are recognized as revenue when received.  The reserve for cancellations is evaluated for each product, and is based on forecasted forward cancellation curves utilizing historical experience, recent trends and credit mix of the customer base.  Our risk related to customer cancellations is limited to the commissions that we receive.  Cancellations fluctuate depending on the volume of ESP and GAP sales, customer financing default or prepayment rates, and shifts in customer behavior related to changes in the coverage or term of the product.  The current portion of estimated cancellation reserves is recognized as a component of other accrued expenses with the remaining amount recognized in other liabilities.  See Note 8 for additional information on cancellation reserves.
	Customers applying for financing who are not approved by CAF may be evaluated by other financial institutions.  Depending on the credit profile of the customer, third-party finance providers generally either pay us or are paid a fixed, pre-negotiated fee per contract.  We recognize these fees at the time of sale.
	We collect sales taxes and other taxes from customers on behalf of governmental authorities at the time of sale.  These taxes are accounted for on a net basis and are not included in net sales and operating revenues or cost of sales.
Cost Of Sales	'
	(Q)  Cost of Sales
	Cost of sales includes the cost to acquire vehicles and the reconditioning and transportation costs associated with preparing the vehicles for resale.  It also includes payroll, fringe benefits and parts and repair costs associated with reconditioning and vehicle repair services.  The gross profit earned by our service department for used vehicle reconditioning service is a reduction of cost of sales.  We maintain a reserve to eliminate the internal profit on vehicles that have not been sold.
Selling, General And Administrative Expenses	'
	(R)  Selling, General and Administrative Expenses
	Selling, general and administrative (“SG&A”) expenses primarily include compensation and benefits, other than payroll related to reconditioning and vehicle repair services; depreciation, rent and other occupancy costs; advertising; and IT expenses, insurance, bad debt, travel, preopening and relocation costs, charitable contributions and other administrative expenses.
Advertising Expenses	'
	(S)  Advertising Expenses
	Advertising costs are expensed as incurred and substantially all are included in SG&A expenses.  Total advertising expenses were $114.6 million in fiscal 2014, $108.2 million in fiscal 2013 and $100.3 million in fiscal 2012.
Store Opening Expenses	'
	(T)  Store Opening Expenses
	Costs related to store openings, including preopening costs, are expensed as incurred and are included in SG&A expenses.
Share-Based Compensation	'
	(U)  Share-Based Compensation
	Share-based compensation represents the cost related to share-based awards granted to employees and non-employee directors.  We measure share-based compensation cost at the grant date, based on the estimated fair value of the award, and we recognize the cost on a straight-line basis (net of estimated forfeitures) over the grantee’s requisite service period, which is generally the vesting period of the award.  We estimate the fair value of stock options using a binomial valuation model.  Key assumptions used in estimating the fair value of options are dividend yield, expected volatility, risk-free interest rate and expected term.  The fair value of restricted stock is based on the volume-weighted average market value on the date of the grant.  The fair value of stock-settled restricted stock units is determined using a Monte-Carlo simulation based on the expected market price of our common stock on the vesting date and the expected number of converted common shares.  Cash-settled restricted stock units are liability awards with fair value measurement based on the market price of CarMax common stock as of the end of each reporting period.  Share-based compensation expense is recorded in either cost of sales, CAF income or SG&A expenses based on the recipients’ respective function.
	We record deferred tax assets for awards that result in deductions on our income tax returns, based on the amount of compensation expense recognized and the statutory tax rate in the jurisdiction in which we will receive a deduction.  Differences between the deferred tax assets recognized for financial reporting purposes and the actual tax deduction reported on the income tax return are recorded in capital in excess of par value (if the tax deduction exceeds the deferred tax asset) or in the consolidated statements of earnings (if the deferred tax asset exceeds the tax deduction and no capital in excess of par value exists from previous awards).  See Note 12 for additional information on stock-based compensation.
Derivative Instruments And Hedging Activities	'
	(V)  Derivative Instruments and Hedging Activities
	We enter into derivative instruments to manage exposures that arise from business activities that result in the future known receipt or payment of uncertain cash amounts, the values of which are impacted by interest rates.  We recognize the derivatives at fair value as either current assets or current liabilities on the consolidated balance sheets, and where applicable, such contracts covered by master netting agreements are reported net.  Gross positive fair values are netted with gross negative fair values by counterparty.  The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting.  We may enter into derivative contracts that are intended to economically hedge certain risks, even though hedge accounting may not apply or we do not elect to apply hedge accounting.  See Note 5 for additional information on derivative instruments and hedging activities.
Income Taxes	'
	(W)  Income Taxes
	We file a consolidated federal income tax return for a majority of our subsidiaries.  Certain subsidiaries are required to file separate partnership or corporate federal income tax returns.  Deferred income taxes reflect the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and the amounts recognized for income tax purposes, measured by applying currently enacted tax laws.  A deferred tax asset is recognized if it is more likely than not that a benefit will be realized.  Changes in tax laws and tax rates are reflected in the income tax provision in the period in which the changes are enacted.
	We recognize tax liabilities when, despite our belief that our tax return positions are supportable, we believe that certain positions may not be fully sustained upon review by tax authorities.  Benefits from tax positions are measured at the highest tax benefit that is greater than 50% likely of being realized upon settlement.  The current portion of these tax liabilities is included in accrued income taxes and any noncurrent portion is included in other liabilities.  To the extent that the final tax outcome of these matters is different from the amounts recorded, the differences impact income tax expense in the period in which the determination is made.  Interest and penalties related to income tax matters are included in SG&A expenses.  See Note 9 for additional information on income taxes.
Net Earnings Per Share	'
	(X)  Net Earnings Per Share
	Basic net earnings per share is computed by dividing net earnings available for basic common shares by the weighted average number of shares of common stock outstanding.  Diluted net earnings per share is computed by dividing net earnings available for diluted common shares by the sum of the weighted average number of shares of common stock outstanding and dilutive potential common stock.  For periods with outstanding participating securities, diluted net earnings per share reflects the more dilutive of the “if-converted” treasury stock method or the two-class method.  For periods with no outstanding participating securities, diluted net earnings per share is calculated using the “if-converted” treasury stock method.  See Note 13 for additional information on net earnings per share.
Recent Accounting Pronouncements	'
	(Y)  Recent Accounting Pronouncements
	In December 2011, the Financial Accounting Standards Board (“FASB”) issued an accounting pronouncement related to offsetting of assets and liabilities on the balance sheet (FASB ASC Topic 210).  The amendments require additional disclosures related to offsetting either in accordance with U.S. GAAP or master netting arrangements.  In January 2013, an update was issued to clarify the scope applies to derivatives.  The provisions of this pronouncement and update are effective for fiscal years, and interim periods within those years, beginning after January 1, 2013.  We adopted this pronouncement for our fiscal year beginning March 1, 2013, and there was no effect on our consolidated financial statements.
	In July 2012, the FASB issued an accounting pronouncement related to intangibles – goodwill and other (FASB ASC Topic 350), which permits companies to first consider qualitative factors as a basis for assessing impairment and determining the necessity of a detailed impairment test of indefinite-lived intangible assets.  The provisions of this pronouncement are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012.  We adopted this pronouncement for our fiscal year beginning March 1, 2013, and there was no effect on our consolidated financial statements.
	In February 2013, the FASB issued an accounting pronouncement related to comprehensive income (FASB ASC Topic 220), requiring improved disclosures of reclassifications out of accumulated other comprehensive income.  The provisions of the pronouncement require an entity to report the amounts reclassified, in their entirety, out of accumulated other comprehensive income and the effect on the respective line items in net income.  For amounts not reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference the amounts to other related disclosures.  This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012.  We adopted this pronouncement for our fiscal year beginning March 1, 2013, and there was no effect on our consolidated financial statements. The required disclosures have been adopted in Note 14.
	In February 2013, the FASB issued an accounting pronouncement related to liabilities (FASB ASC Topic 405).  The amendments provide guidance on the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements, including debt arrangements, other contractual obligations, and settled litigation and judicial rulings.  This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013.  We will adopt this pronouncement for our fiscal year beginning March 1, 2014.  We do not expect this pronouncement to have a material effect on our consolidated financial statements.
	In July 2013, the FASB issued an accounting pronouncement related to derivatives and hedging (FASB ASC Topic 815), which allows the use of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a benchmark interest rate for hedge accounting purposes in addition to interest rates on direct Treasury obligations of the United States government and LIBOR.  In addition, the guidance removes the restriction on using different benchmark rates for similar hedges.  The pronouncement became effective on a prospective basis for qualifying new or designated hedging relationships entered into on or after July 17, 2013.  It did not have a material effect on our consolidated financial statements.
	In July 2013, the FASB issued an accounting pronouncement related to income taxes (FASB ASC Topic 740), which provides guidance regarding the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar loss or a tax credit carryforward exists.  Under certain circumstances, unrecognized tax benefits should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward.  This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, with early adoption permitted.  We will adopt this pronouncement for our fiscal year beginning March 1, 2014.  We do not expect this pronouncement to have a material effect on our consolidated financial statements.
