Accounting Policies [Abstract] |
Consolidation, Policy [Policy Text Block] | Principles of Consolidation The consolidated financial statements include the accounts of America’s Car-Mart, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated.
Segment Reporting, Policy [Policy Text Block] | Segment Information Each dealership is an operating segment with its results regularly reviewed by the Company’s chief operating decision maker in an effort to make decisions about resources to be allocated to the segment and to assess its performance. Individual dealerships meet the aggregation criteria for reporting purposes under the current accounting guidance. The Company operates in the Integrated Auto Sales and Finance segment of the used car market, also referred to as the Integrated Auto Sales and Finance industry. In this industry, the nature of the sale and the financing of the transaction, financing processes, the type of customer and the methods used to distribute the Company’s products and services, including the actual servicing of the contracts as well as the regulatory environment in which the Company operates all have similar characteristics. Each of our individual dealerships is similar in nature and only engages in the selling and financing of used vehicles. All individual dealerships have similar operating characteristics. As such, individual dealerships have been aggregated into one reportable segment.
Use of Estimates, Policy [Policy Text Block] | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates. Significant estimates include, but are not limited to, the Company’s allowance for credit losses.
Concentration Risk, Credit Risk, Policy [Policy Text Block] | Concentration of Risk The Company provides financing in connection with the sale of substantially all of its vehicles. These sales are made primarily to customers residing in Alabama, Arkansas, Georgia, Kentucky, Mississippi, Missouri, Oklahoma, Tennessee, and Texas, with approximately 32% of revenues resulting from sales to Arkansas customers. Periodically, the Company maintains cash in financial institutions in excess of the amounts insured by the federal government. The Company’s revolving credit facilities mature in October 2017. The Company expects that these credit facilities will be renewed or refinanced on or before the scheduled maturity dates.
Line of Credit Facility, Dividend Restrictions [Policy Text Block] | Restrictions on Distributions/Dividends The Company’s revolving credit facilities generally restrict distributions by the Company to its shareholders. The distribution limitations under the Credit Facilities allow the Company to repurchase the Company’s stock so long as: either (a) the aggregate amount of such repurchases does not exceed $40 million beginning October 8, 2014 and the sum of borrowing bases combined minus the principal balances of all revolver loans after giving effect to such repurchases is equal to or greater than 30% of the sum of the borrowing bases, or (b) the aggregate amount of such repurchases does not exceed 75% of the consolidated net income of the Company measured on a trailing twelve month basis; provided that immediately before and after giving effect to the stock repurchases, at least 12.5% of the aggregate funds committed under the credit facilities remain available. Thus, the Company is limited in its ability to pay dividends or make other distributions to its shareholders without the consent of the Company’s lenders.
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash Equivalents The Company considers all highly liquid instruments purchased with original maturities of three months or less to be cash equivalents.
Finance, Loans and Leases Receivable, Policy [Policy Text Block] | Finance Receivables, Repossessions and Charge-offs and Allowance for Credit Losses The Company originates installment sale contracts from the sale of used vehicles at its dealerships. These installment sale contracts typically carry interest rates ranging from 14% to 15% using the simple effective interest method including any deferred fees. Contract origination costs are not significant. The installment sale contracts are not pre-computed contracts whereby borrowers are obligated to pay back principal plus the full amount of interest that will accrue over the entire term of the contract. Finance receivables are collateralized by vehicles sold and consist of contractually scheduled payments from installment contracts net of unearned finance charges and an allowance for credit losses. Unearned finance charges represent the balance of interest receivable to be earned over the entire term of the related installment contract, less the earned amount ($2.0 million at April 30, 2015 and $1.8 million at April 30, 2014), and as such, has been reflected as a reduction to the gross contract amount in arriving at the principal balance in finance receivables. An account is considered delinquent when a contractually scheduled payment has not been received by the scheduled payment date. While the Company does not formally place contracts on nonaccrual status, the immaterial amount of interest that may accrue after an account becomes delinquent up until the point of resolution via repossession or write-off, is reserved for against the accrued interest on the Consolidated Balance Sheets. Delinquent contracts are addressed and either made current by the customer, which is the case in most situations, or the vehicle is repossessed or written off if the collateral cannot be recovered quickly. Customer payments are set to match their payday with approximately 73% of payments due on either a weekly or bi-weekly basis. The frequency of the payment due dates combined with the declining value of collateral lead to prompt resolutions on problem accounts. Accounts are delinquent when the customer is one day or more behind on their contractual payments. At April 30, 2015, 5.8% of the Company’s finance receivables balances were 30 days or more past due compared to 4.4% at April 30, 2014. Substantially all of the Company’s automobile contracts involve contracts made to individuals with impaired or limited credit histories, or higher debt-to-income ratios than permitted by traditional lenders. Contracts made with buyers who are restricted in their ability to obtain financing from traditional lenders generally entail a higher risk of delinquency, default and repossession, and higher losses than contracts made with buyers with better credit. The Company strives to keep its delinquency percentages low, and not to repossess vehicles. Accounts two days late are sent a notice in the mail. Accounts three days late are contacted by telephone. Notes from each telephone contact are electronically maintained in the Company’s computer system. If a customer becomes severely delinquent in his or her payments, and management determines that timely collection of future payments is not probable, the Company will take steps to repossess the vehicle. The Company attempts to resolve payment delinquencies amicably prior to repossessing a vehicle. Periodically, the Company enters into contract modifications with its customers to extend or modify the payment terms. The Company only enters into a contract modification or extension if it believes such action will increase the amount of monies the Company will ultimately realize on the customer’s account and will increase the likelihood of the customer being able to pay off the vehicle contract. At the time of modification, the Company expects to collect amounts due including accrued interest at the contractual interest rate for the period of delay. Other than the extension of additional time, concessions are not granted to customers at the time of modifications. Modifications are minor and are made for payday changes, minor vehicle repairs and other reasons. For those vehicles that are repossessed, the majority are returned or surrendered by the customer on a voluntary basis. Other repossessions are performed by Company personnel or third party repossession agents. Depending on the condition of a repossessed vehicle, it is either resold on a retail basis through a Company dealership, or sold for cash on a wholesale basis primarily through physical or online auctions. The Company takes steps to repossess a vehicle when the customer becomes delinquent in his or her payments and management determines that timely collection of future payments is not probable. Accounts are charged-off after the expiration of a statutory notice period for repossessed accounts, or when management determines that the timely collection of future payments is not probable for accounts where the Company has been unable to repossess the vehicle. For accounts with respect to which the vehicle was repossessed, the fair value of the repossessed vehicle is charged as a reduction of the gross finance receivables balance charged-off. On average, accounts are approximately 67 days past due at the time of charge-off. For previously charged-off accounts that are subsequently recovered, the amount of such recovery is credited to the allowance for credit losses. The Company maintains an allowance for credit losses on an aggregate basis, as opposed to a contract-by-contract basis, at an amount it considers sufficient to cover estimated losses inherent in the portfolio at the balance sheet date in the collection of its finance receivables currently outstanding. The Company accrues an estimated loss as it is probable that the entire amount will not be collected and the amount of the loss can be reasonably estimated in the aggregate. The allowance for credit losses is based primarily upon historical credit loss experience, with consideration given to recent credit loss trends and changes in contract characteristics (i.e., average amount financed and term), delinquency levels, collateral values, economic conditions and underwriting and collection practices. The allowance for credit losses is periodically reviewed by management with any changes reflected in current operations. Although it is at least reasonably possible that events or circumstances could occur in the future that are not presently foreseen which could cause actual credit losses to be materially different from the recorded allowance for credit losses, the Company believes that it has given appropriate consideration to all relevant factors and has made reasonable assumptions in determining the allowance for credit losses. The calculation of the allowance for credit losses uses the following primary factors:
| · | The number of units repossessed or charged-off as a percentage of total units financed over specific historical periods of time from one year to five years.
| · | The average net repossession and charge-off loss per unit during the last eighteen months, segregated by the number of months since the contract origination date, and adjusted for the expected future average net charge-off loss per unit. Approximately 50% of the charge-offs that will ultimately occur in the portfolio are expected to occur within 10-11 months following the balance sheet date. The average age of an account at charge-off date is 11 months.
| · | The timing of repossession and charge-off losses relative to the date of sale (i.e., how long it takes for a repossession or charge-off to occur) for repossessions and charge-offs occurring during the last eighteen months.
A point estimate is produced by this analysis which is then supplemented by any positive or negative subjective factors to arrive at an overall reserve amount that management considers to be a reasonable estimate of losses inherent in the portfolio at the balance sheet date that will be realized via actual charge-offs in the future. While challenging economic conditions can negatively impact credit losses, the effectiveness of the execution of internal policies and procedures within the collections area and the competitive environment on the lending side have historically had a more significant effect on collection results than macro-economic issues. An increase to the allowance for credit losses was made in the third quarter of fiscal 2014 which resulted in a $7.7 million charge to the provision for credit losses based on the analysis discussed above and the increased level of charge-offs with the expectation that charge-offs related to a significant extent to increased competition on the lending side will remain elevated. Although the Company saw a decrease in the level of charge-offs as a percentage of average finance receivables for fiscal 2015 compared to fiscal 2014, it is still experiencing elevated credit losses. In most states, the Company offers retail customers who finance their vehicle the option of purchasing a payment protection plan product as an add-on to the installment sale contract. This product contractually obligates the Company to cancel the remaining principal outstanding for any contract where the retail customer has totaled the vehicle, as defined, or the vehicle has been stolen. The Company periodically evaluates anticipated losses to ensure that if anticipated losses exceed deferred payment protection plan revenues, an additional liability is recorded for such difference. No such liability was required at April 30, 2015 or 2014.

The Company periodically evaluates anticipated losses to ensure that if anticipated losses exceed deferred payment protection plan revenues, an additional liability is recorded for such difference. No such liability was required at April 30, 2015 or 2014. Inventory Inventory consists of used vehicles and is valued at the lower of cost or market on a specific identification basis. Vehicle reconditioning costs are capitalized as a component of inventory. Repossessed vehicles and trade-in vehicles are recorded at fair value, which approximates wholesale value. The cost of used vehicles sold is determined using the specific identification method. Goodwill Goodwill reflects the excess of purchase price over the fair value of specifically identified net assets purchased. Goodwill and intangible assets deemed to have indefinite lives are not amortized but are subject to annual impairment tests at the Company’s year-end. The impairment tests are based on the comparison of the fair value of the reporting unit to the carrying value of such unit. If the fair value of the reporting unit falls below its carrying value, the Company performs the second step of the two-step goodwill impairment process to determine the amount, if any, that the goodwill is impaired. The second step involves determining the fair value of the identifiable assets and liabilities and the implied goodwill. The implied goodwill is compared to the carrying value of the goodwill to determine the impairment, if any. There was no impairment of goodwill during fiscal 2015 or fiscal 2014. Property and Equipment Property and equipment are stated at cost. Expenditures for additions, remodels and improvements are capitalized. Costs of repairs and maintenance are expensed as incurred. Leasehold improvements are amortized over the shorter of the estimated life of the improvement or the lease period. The lease period includes the primary lease term plus any extensions that are reasonably assured. Depreciation is computed principally using the straight-line method generally over the following estimated useful lives:
Furniture, fixtures and equipment (years) | 3 | to | 7
Leasehold improvements (years) | 5 | to | 15
Buildings and improvements (years) | 18 | to | 39
Property and equipment are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying values of the impaired assets exceed the fair value of such assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. Cash Overdraft As checks are presented for payment from the Company’s primary disbursement bank account, monies are automatically drawn against cash collections for the day and, if necessary, are drawn against one of its revolving credit facilities. Any cash overdraft balance principally represents outstanding checks, net of any deposits in transit that as of the balance sheet date had not yet been presented for payment. Any cash overdraft balance is reflected in accrued liabilities on the Company’s Consolidated Balance Sheets. Deferred Sales Tax Deferred sales tax represents a sales tax liability of the Company for vehicles sold on an installment basis in the states of Alabama and Texas. Under Alabama and Texas law, for vehicles sold on an installment basis, the related sales tax is due as the payments are collected from the customer, rather than at the time of sale. Deferred sales tax liabilities are reflected in accrued liabilities on the Company’s Consolidated Balance Sheets. Income Taxes Income taxes are accounted for under the liability method. Under this method, deferred income tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates expected to apply in the years in which these differences are expected to be recovered or settled. Occasionally, the Company is audited by taxing authorities. These audits could result in proposed assessments of additional taxes. The Company believes that its tax positions comply in all material respects with applicable tax law. However, tax law is subject to interpretation, and interpretations by taxing authorities could be different from those of the Company, which could result in the imposition of additional taxes. The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company applies this methodology to all tax positions for which the statute of limitations remains open. The Company is subject to income taxes in the U.S. federal jurisdiction and various state jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. With few exceptions, the Company is no longer subject to U.S. federal, state and local income tax examinations by tax authorities for the fiscal years before 2012. In April 2014, the IRS completed the examinations of the Company’s income tax returns for fiscal years 2010 and 2011. The examinations resulted in timing adjustments and a net refund for the years being audited. The Company’s policy is to recognize accrued interest related to unrecognized tax benefits in interest expense and penalties in operating expenses. The Company had no accrued penalties or interest as of April 30, 2015 and 2014, respectively. Revenue Recognition Revenues are generated principally from the sale of used vehicles, which in most cases includes a service contract and a payment protection plan product, and interest income and late fees earned on finance receivables. Revenues are net of taxes collected from customers and remitted to government agencies. Cost of vehicle sales include costs incurred by the Company to prepare the vehicle for sale including license and title costs, gasoline, transport services and repairs. Revenues from the sale of used vehicles are recognized when the sales contract is signed, the customer has taken possession of the vehicle and, if applicable, financing has been approved. Revenues from the sale of vehicles sold at wholesale are recognized at the time the proceeds are received. Revenues from the sale of service contracts are recognized ratably over the expected duration of the product. Service contract revenues are included in sales and the related expenses are included in cost of sales. Payment protection plan revenues are initially deferred and then recognized to income using the “Rule of 78’s” interest method over the life of the contract so that revenues are recognized in proportion to the amount of cancellation protection provided. Payment protection plan revenues are included in sales and related losses are included in cost of sales as incurred. Interest income is recognized on all active finance receivables accounts using the simple effective interest method. Active accounts include all accounts except those that have been paid-off or charged-off. Sales consist of the following for the years ended April 30, 2015, 2014 and 2013:
|  | Years Ended April 30, |
(In thousands) |  | 2015 |  |  | 2014 |  |  | 2013 |
Sales – used autos |  | $ | 416,060 |  |  | $ | 385,672 |  |  | $ | 368,674 |
Wholesales – third party |  |  | 19,961 |  |  |  | 18,886 |  |  |  | 19,718 |
Service contract sales |  |  | 19,758 |  |  |  | 15,833 |  |  |  | 14,594 |
Payment protection plan revenue |  |  | 16,790 |  |  |  | 14,113 |  |  |  | 12,754 |
Total |  | $ | 472,569 |  |  | $ | 434,504 |  |  | $ | 415,740 |
At April 30, 2015 and 2014, finance receivables more than 90 days past due were approximately $2.8 million and $1.2 million, respectively. Late fee revenues totaled approximately $2.2 million, $2.2 million and $2.0 million for the fiscal years ended 2015, 2014 and 2013, respectively. Late fee revenue is recognized when collected and is reflected within Interest and other income on the Consolidated Statements of Operations. Advertising Costs Advertising costs are expensed as incurred and consist principally of radio, television and print media marketing costs. Advertising costs amounted to $3.6 million, $4.2 million and $4.1 million for the years ended April 30, 2015, 2014 and 2013, respectively. Employee Benefit Plans The Company has 401(k) plans for all of its employees meeting certain eligibility requirements. The plans provide for voluntary employee contributions and the Company matches 50% of employee contributions up to a maximum of 4% of each employee’s compensation. The Company contributed approximately $363,000, $329,000, and $290,000 to the plans for the years ended April 30, 2015, 2014 and 2013, respectively. The Company offers employees the right to purchase common shares at a 15% discount from market price under the 2006 Employee Stock Purchase Plan which was approved by shareholders in October 2006. The Company takes a charge to earnings for the 15% discount. Amounts for fiscal years 2015, 2014 and 2013 were not material individually and in the aggregate. A total of 200,000 shares were registered and 159,556 remain available for issuance under this plan at April 30, 2015. Earnings per Share Basic earnings per share are computed by dividing net income attributable to common stockholders by the average number of common shares outstanding during the period. Diluted earnings per share are computed by dividing net income attributable to common stockholders by the average number of common shares outstanding during the period plus dilutive common stock equivalents. The calculation of diluted earnings per share takes into consideration the potentially dilutive effect of common stock equivalents, such as outstanding stock options and non-vested restricted stock, which if exercised or converted into common stock would then share in the earnings of the Company. In computing diluted earnings per share, the Company utilizes the treasury stock method and anti-dilutive securities are excluded. Stock-Based Compensation The Company recognizes the cost of employee services received in exchange for awards of equity instruments, such as stock options and restricted stock, based on the fair value of those awards at the date of grant over the requisite service period. The Company uses the Black-Scholes option pricing model to determine the fair value of stock option awards. The Company may issue either new shares or treasury shares upon exercise of these awards. Stock-based compensation plans, related expenses, and assumptions used in the Black-Scholes option pricing model are more fully described in Note K. Treasury Stock The Company purchased 442,700, 325,598, and 398,548 shares of its common stock to be held as treasury stock for a total cost of $20.0 million, $12.8 million and $17.3 million during the years ended April 30, 2015, 2014 and 2013, respectively. Treasury stock may be used for issuances under the Company’s stock-based compensation plans or for other general corporate purposes. Recent Accounting Pronouncements Occasionally, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies which the Company adopts as of the specified effective date. Unless otherwise discussed, the Company believes the impact of recently issued standards which are not yet effective will not have a material impact on its consolidated financial statements upon adoption.

Treasury stock may be used for issuances under the Company’s stock-based compensation plans or for other general corporate purposes.
New Accounting Pronouncements, Policy [Policy Text Block] | Recent Accounting Pronouncements Occasionally, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies which the Company adopts as of the specified effective date. Unless otherwise discussed, the Company believes the impact of recently issued standards which are not yet effective will not have a material impact on its consolidated financial statements upon adoption. Revenue Recognition. In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes existing revenue recognition guidance. The new guidance in ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for annual and interim periods beginning after December 15, 2016, using one of two retrospective application methods. The Company is currently evaluating the potential effects of the adoption of this update on the consolidated financial statements. Debt Issuance Costs. In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, which amends the current presentation of debt issuance costs in the financial statements. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts, instead of as an asset. The amendments are to be applied retrospectively and are effective for interim and annual periods beginning after December 15, 2015. The adoption of the new guidance is not expected to have a material impact on the Company’s consolidated financial statements.
Reclassification, Policy [Policy Text Block] | Reclassifications The Company has made reclassifications to certain amounts in the accompanying Condensed Consolidated Balance Sheet as of April 30, 2014 to reclassify approximately $4.2 million of deferred service contract revenue from accrued liabilities to deferred service contract revenue. The reclassifications did not have an impact on net income or earnings per share.
