Shipping and handling fees billed to customers are included in net sales. Revenues for gift certificate sales and store credits are recognized upon redemption. Prior to recognition as a sale, gift certificates are recorded as accrued liabilities on the balance sheet. Based on historical redemption rates, gift certificates and store credits, not subject to unclaimed property laws, are recorded as income. Gift certificates and store credits outstanding and subject to unclaimed property laws are maintained as accrued liabilities until remitted in accordance with local ordinances. Sales of consignment merchandise are recognized at such time as the merchandise is sold and are recorded on a gross basis because the Company is the primary obligor of the transaction, has general latitude on setting the price, has discretion as to the suppliers, is involved in the selection of the product and has inventory loss risk. Sales are reported net of returns and sales taxes. The Company generally gives its customers the right to return merchandise purchased by them within 10 to 90 days, depending on the product sold and records a provision at the time of sale for the effect of the estimated returns. Revenues for repair services are recognized when the service is delivered to and accepted by the customer. Revenue related to the Company’s purchases of gold and other precious metals from our customers are recognized when the Company delivers the goods, and receives and accepts an offer from a refiner to purchase the gold and other precious metal. </div>falsefalsefalsenonnum:textBlockItemTypenaDisclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue.

Several installment sales plans are offered to the Mayors credit card holders which vary as to repayment terms and finance charges assessed. Finance charges on Mayors’ consumer credit receivables, when applicable, accrue at rates ranging from 7.9% to 18% per annum. Finance charges on Mayors consumer credit accounts are not significant. The Company maintains allowances for doubtful accounts associated with the accounts receivable recorded on the balance sheet for estimated losses resulting from the inability of its customers to make required payments. The allowance is determined based on a combination of factors including, but not limited to, the length of time that the receivables are past due, the Company’s knowledge of the customer, economic and market conditions and historical write-off experiences. The Company classifies a receivable account as past due if a required payment amount has not been received within the allotted time frame (generally 30 days), after which internal collection efforts commence. Once all internal collection efforts have been exhausted and management has reviewed the account, the account is put on nonaccrual status and may be sent for external collection or legal action. Upon the suspension of the accrual of interest, interest income is recognized to the extent cash payments received exceed the balance of the principal amount owed on the account. After all collection efforts have been exhausted, including internal and external collection efforts, an account is written off. The Company guarantees a portion of its private label credit card sales to its credit card vendor. The Company maintains a liability associated with these outstanding amounts. Similar to the allowance for doubtful accounts, the liability related to these guaranteed sales amounts are based on a combination of factors including the length of time the receivables are past due to the Company’s credit card vendor, the Company’s knowledge of the customer, economic and market conditions and historical write-off experiences of similar credits.

The amendments in this standard require that all non-owner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The Company adopted this guidance effective for the fiscal year ended March 30, 2013, and applied the recommendation retrospectively for fiscal years ended March 31, 2012, and March 26, 2011.
