Long-term Debt, Description	During the 52 weeks ended April 29, 2023, we incurred debt issuance costs totaling $3,184 related to the Term Loan Credit Agreement. The debt issuance costs have been deferred and are presented as a reduction to the long-term borrowings in the consolidated balance sheets, and subsequently amortized ratably over the term of the Term Loan Facility.The Term Loans accrue interest at a rate equal to 11.25%, payable quarterly. We have the right, through December 31, 2022, to pay all or a portion of the interest on the Term Loans in kind. To date, all interest on the term loan has been paid in cash. The Term Loans do not amortize prior to maturity. Solely to the extent that any Term Loans remain outstanding on June 7, 2023, we paid a fee of 1.5% of the outstanding principal amount of the Term Loans on such date. The Term Loan Credit Agreement does not contain a financial covenant, but otherwise contains representations and warranties, covenants and events of default that are substantially the same as those in the Credit Agreement, including restrictions on the ability of the Company and its subsidiaries to incur additional debt, incur or permit liens on assets, make investments and acquisitions, consolidate or merge with any other company, engage in asset sales and make dividends and distributions. The Term Loan Facility is secured by second-priority liens on all assets securing the obligations under the Credit Agreement, which is all of the assets of the Company and the Guarantors, subject to customary exclusions and limitations set forth in the Term Loan Credit Agreement and the other loan documents executed in connection therewith.The Credit Agreement amendment permitted us to incur the Term Loan Facility and also provides that, upon repayment of the Term Loan Credit Agreement (and, if applicable, any replacement credit facility thereof), we may incur second lien secured debt in an aggregate principal amount not to exceed $75,000
