Receivables [Abstract]
Receivables	Note 9. Receivables We invoice customers based on a billing schedule as established in our contracts.

Foreign sales are at times secured by irrevocable letters of credit or bank guarantees. Accounts receivable are reported net of an allowance for doubtful accounts of $2,828 and $2,208 at May 2, 2020 and April 27, 2019, respectively. Included in accounts receivable as of May 2, 2020 and April 27, 2019 was $687 and $440, respectively, of retainage on construction-type contracts, all of which is expected to be collected within one year. In some contracts with customers, we agree to installment payments exceeding 12 months. The present value of these contracts is recorded as a receivable as the revenue is recognized in accordance with GAAP, 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, including accrued interest and current maturities, was $4,633 and $3,514 as of May 2, 2020 and April 27, 2019, respectively. Contract receivables bearing annual interest rates of 5.0 to 9.0 percent are due in varying annual installments through August 2024.
