Our revolving credit facility as of December 29, 2018, had a net aggregate availability of $300 million. The credit facility is for general corporate purposes, to meet our seasonal working capital requirements and to repurchase our stock. The credit agreement provides the lenders with a collateral security interest in substantially all of our assets and those of our subsidiaries and requires us to comply with, among other things, a maximum leverage ratio and a minimum interest coverage ratio. Under the terms of the credit agreement we pay a variable rate of interest and a commitment fee based on our leverage ratio. We were in compliance with all financial covenants as of December 29, 2018.

The following tables summarizes our borrowings under the credit facility ($ in thousands):

In February 2019, we amended our revolving credit facility (Credit Agreement, as amended) to increase our net aggregate availability from $300 million to $450 million. We maintained the accordion feature which allows us to increase the amount of the credit facility from $450 million to $600 million, subject to Lenders’ approval. The Credit Agreement, as amended, matures in February 2024. There were no other significant changes to the credit facility’s terms and conditions.
