Receivables

Accounts receivable are reported net of an allowance for doubtful accounts of $2,633 and $2,539 at August 2, 2014 and April 26, 2014, respectively.

In connection with certain sales transactions, we have entered into sales contracts with installment payments exceeding six months and sales-type leases. The present value of these contracts and leases is recorded as a receivable as the revenue is recognized in accordance with generally accepted accounting principles, and profit is recognized to the extent the present value is in excess of cost. We generally retain a security interest in the equipment or in the cash flow generated by the equipment until the contract is paid. The present value of long-term contracts and lease receivables, including accrued interest and current maturities, was $11,841 and $13,112 as of August 2, 2014 and April 26, 2014, respectively. Contract and lease receivables bearing annual interest rates of 5.0 to 10.0 percent are due in varying annual installments through July 2022. The face amount of long-term receivables was $13,866 as of August 2, 2014 and $14,892 as of April 26, 2014. Included in accounts receivable as of August 2, 2014 and April 26, 2014 was $2,187 and $2,098, respectively, of retainage on construction-type contracts, all of which is expected to be collected within one year.
