In addition, the amendment requires the achievement of a Specified Event (as described above) by no later than May 31, 2023 (as such date may be extended under the Credit Agreement, but no later than August 31, 2023 without consent from lenders under the Term Loan Credit Agreement). For additional information, see the Company's Report on Form 8-K dated March 8, 2023 and filed with the SEC on March 9, 2023.During the 52 weeks ended April 29, 2023, we incurred debt issuance costs totaling $431 related to the March 2023 Term Loan Credit Agreement amendment.

The Term Loans accrue interest at a rate equal to 11.25%, payable quarterly. All interest on the Term Loan prior to the July 29, 2023 was paid in cash. During the 13 weeks ended October 28, 2023, all interest on the Term Loan was incurred in kind as permitted under the July 2023 Term Loan Amendment. The Term Loans do not amortize prior to maturity. 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.
