As of April 2, 2021, we had cash and cash equivalents of $25.4 million. This amount represents cash on hand in business checking accounts with BMO.
We do not engage in trading activities and do not participate in foreign currency transactions.
We are subject to interest rate risk in connection with our Term A Loan and borrowings, if any, under our revolving credit facility and delayed draw term loan, each of which bears interest at variable rates. As of April 2, 2021, $82.5 million was outstanding under our Term A Loan, $26.3 million was outstanding under our delayed draw term loan, no borrowed amounts were outstanding and $2.7 million in letters of credit were issued under the revolving credit facility. Each of our Term A Loan, revolving credit facility and delayed draw term loan mature as of June 26, 2024 and are governed by our credit agreement, as amended.
Pursuant to the Fourth Amendment, (as described in Part I, Item 1, Note 13, “Subsequent Events,” of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q), borrowings under the credit agreement bear interest at all times other than during the initial covenant relief period granted by the Third Amendment, at either a Base Rate or LIBOR, each as defined in the credit agreement,, at our option, and, in each case, plus an applicable margin, which applicable margin will range from 0.125% to 1.25% with respect to Base Rate borrowings and 1.125% to 2.25% with respect to LIBOR borrowings, depending on our consolidated leverage ratio; provided that LIBOR cannot be less than 0.00%. We will also pay a commitment fee for the unused portion of the revolving credit facility and the delayed draw term loan facility, which ranges from 0.15% to 0.40% per annum depending on our consolidated leverage ratio, and fees on the face amount of any letters of credit outstanding under the revolving credit facility, which range from 0.84% to 1.688% per annum, in each case, depending on whether such letter of credit is a performance or financial letter of credit and the Leverage Ratio.
The Term A Loan amortizes quarterly in installments of $2.5 million beginning with the fiscal quarter ending September 27, 2019, with a final payment of all then remaining principal and interest due on the maturity date of June 26, 2024, subject to certain prepayment obligations based on our excess cash flow. Each borrowing under our delayed draw term loan will amortize quarterly in an amount equal to 2.5% of the aggregate outstanding borrowings under the delayed draw term loan, beginning with the first full fiscal quarter ending after the initial borrowing date, with a final payment of all then remaining principal and interest due on the maturity date of June 26, 2024, subject to certain prepayment obligations based on our excess cash flow.
On January 31, 2019, we entered into an interest swap agreement for $35.0 million notional amount. The interest swap agreement was designated as a cash flow hedge to fix the variable interest rate on a portion of the outstanding principal amount under our prior term loan facility. The interest swap fixed rate is 2.47% and the amortization is quarterly in an amount equal to 10% annually. The interest swap agreement expires on January 31, 2022.
Based upon the amount of our outstanding indebtedness as of April 2, 2021, a one percentage point increase in the effective interest rate would change our annual interest expense by approximately $1.1 million in 2021.
Risk Related to Potential LIBOR Transition
All of our $108.8 million of debt outstanding under our credit agreement as of April 2, 2021 bears interest at a floating rate that uses LIBOR as the applicable reference rate to calculate the interest. The Chief Executive of the U.K. Financial Conduct Authority (the “FCA”), which regulates the London Interbank Offered Rate, or LIBOR, has announced that the FCA will no longer persuade or compel banks to submit rates for the calculation of LIBOR after 2021. However, for U.S dollar LIBOR, it appears that the relevant date may be deferred to June 30, 2023 for certain tenors (including overnight and one, three, six and 12 months), at which time the LIBOR administrator has indicated that it intends to cease publication of U.S. dollar LIBOR. Despite this potential deferral, the LIBOR administrator has advised that no new contracts using U.S. dollar LIBOR should be entered into after December 31, 2021. These actions indicate that the continuation of U.S. LIBOR on the current basis cannot and will not be guaranteed after June 30, 2023. Moreover, it is possible that U.S. LIBOR will be discontinued or modified prior to June 30, 2023. The U.S. Federal
