Debt instrument description of variable interest rate |  |  | On April 30, 2020, the Credit Agreement was amended to include an incremental DDTL of $20.5 million (the “Incremental DDTL”) that is available to draw upon before March 31, 2021, and matures on April 29, 2021, for a total credit facility of $150.5 million. As of and for the nine months ended November 1, 2020, no amount of the Incremental DDTL was funded. The loan covenants were also amended to allow for greater flexibility during the Company’s peak borrowing periods in fiscal 2020. The interest rate applicable to the Revolver or DDTL will be a fixed rate for a one-, two-, three- or six-month interest period equal to LIBOR (with a 1% floor) for such interest period plus a margin of 225 to 300 basis points, based upon the Company’s rent adjusted leverage ratio (effective rate of 3.5% for the Revolver and the DDTL at November 1, 2020). The interest rate applicable to the Incremental DDTL will also be a fixed rate over the aforementioned interest periods equal to LIBOR (with a 1% floor) for such interest period plus a margin of 275 to 350 basis points.
