New Accounting Standards

In April 2015, the FASB amended its existing accounting standards for the presentation of debt issuance costs in the statement of financial position. The amendments generally require that the issuance costs related to a recognized debt obligation be presented as a deduction from the carrying amount of the debt obligation, with the associated amortization recognized as a component of interest expense. The amendments were effective for beginning February 1, 2016 on a retrospective basis; the Company adopted the standard for issuance costs incurred related to its revolving line of credit. The adoption resulted in the reclassification of $84,000 from prepaid expenses and other current assets to current portion of long-term debt, $125,000 from other accrued liabilities to current portion of long-term debt and $69,000 from other assets to long-term debt to as of January 31, 2016. The adoption resulted in the reclassification of $84,000 from prepaid expenses and other current assets to current portion of long-term debt, $125,000 from other accrued liabilities to current portion of long-term debt and $110,000 from other assets to long-term debt as of July 31, 2015.
