3.00% Senior Convertible Notes due 2025 On June 2, 2020, in an effort to refinance our debt structure, we issued $175.0 million in aggregate principal amount of 3.00% Convertible Senior Notes due 2025 (the “Notes”), including the initial purchasers’ exercise in full of their option to purchase an additional $25.0 million principal amount of the Notes, between the Company and U.S. Bank National Association, as trustee (the “Trustee”), in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The net proceeds from the issuance of the Notes were $169.8 million after deducting transaction costs. We used net proceeds from the issuance of the Notes to repay a portion of our indebtedness under the Credit Agreement, dated October 1, 2019, by and among the Company, the lenders and issuing banks party thereto and Barclays Bank PLC, as administrative agent (the “Existing Facility”). The Notes are senior, unsecured obligations and will accrue interest payable semiannually in arrears on June 1 and December 1 of each year, beginning on December 1, 2020, at a rate of 3.00% per year. The Notes will mature on June 1, 2025, unless earlier converted, redeemed, or repurchased. The Notes are convertible into cash, shares of Common Stock or a combination of cash and shares of Common Stock, at the Company’s election. The conversion rate will initially be 26.7271 shares of our Common Stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $37.42 per share of our Common Stock). As of June 30, 2021, the carrying amount of the equity component, net of taxes and transaction costs was $14.4 million. The interest expense recognized related to the Notes for the three and nine months ended June 30, 2021 was as follows (dollars in thousands):
|  | Three Months Ended June 30, |  |  | Nine Months Ended June 30, |
|  | 2021 |  |  | 2020 |  |  | 2021 |  |  | 2020 |
Contractual interest expense |  | $ | 1,308 |  |  | $ | 431 |  |  | $ | 3,924 |  |  | $ | 431 |
Amortization of debt discount |  |  | 886 |  |  |  | 276 |  |  |  | 2,617 |  |  |  | 276 |
Amortization of issuance costs |  |  | 223 |  |  |  | 70 |  |  |  | 658 |  |  |  | 70 |
Total interest expense related to the Notes |  | $ | 2,417 |  |  | $ | 777 |  |  | $ | 7,199 |  |  | $ | 777 |
The conditional conversion feature of the Notes was triggered during the nine months ended June 30, 2021, and the Notes were convertible during the fiscal quarter ended June 30, 2021, with no Notes being converted. Whether any of the Notes will be convertible in future quarters will depend on the satisfaction of one or more of the conversion conditions in the future. If one or more holders elect to convert their Notes at a time when any such Notes are convertible, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity. Senior Credit Facilities On June 12, 2020 (the “Financing Closing Date”), in connection with our effort to refinance our existing indebtedness, we entered into a Credit Agreement, by and among the Borrower, the lenders and issuing banks party thereto and Wells Fargo Bank, N.A., as administrative agent (the “Credit Agreement”), consisting of a four-year senior secured term loan facility in the aggregate principal amount of $125.0 million (the “Term Loan Facility”). The net proceeds from the issuance of the Term Loan Facility were $123.0 million, which together with proceeds from the Convertible Senior Notes was intended to pay in full all indebtedness under the Existing Facility, and paid fees and expenses in connection with the Senior Credit Facilities. We also entered into a senior secured first-lien revolving credit facility in an aggregate principal amount of $50.0 million (the “Revolving Facility” and, together with the Term Loan Facility, the “Senior Credit Facilities”), which shall be drawn on in the event that our working capital and other cash needs are not supported by our operating cash flow. As of June 30, 2021, there were no amounts outstanding under the Revolving Facility. On December 17, 2020 (the “Amendment No. 1 Effective Date”), we entered into Amendment No. 1 to the Credit Agreement (the “Amendment”). The Amendment extended the scheduled maturity date of the revolving credit and term facilities from June 12, 2024 to April 1, 2025. The Amendment was accounted for as a debt modification, and therefore, $0.5 million of the refinancing fees paid directly to lender were recorded as deferred debt issuance costs, and $0.1 million of the refinancing fees paid to third parties were expensed in the period. The Amendment, among other things, revised certain interest rates in the Credit Agreement. Following delivery of a compliance certificate for the first full fiscal quarter after the Amendment No. 1 Effective Date, the applicable margins for the revolving credit and term facilities is subject to a pricing grid based upon the net total leverage ratio as follows (i) if the net total leverage ratio is greater than 3.00 to 1.00, the applicable margin is LIBOR plus 3.00% or ABR plus 2.00%; (ii) if the net total leverage ratio is less than or equal to 3.00 to 1.00 but greater than 2.50 to 1.00, the applicable margin is LIBOR plus 2.75% or ABR plus 1.75%; (iii) if the net total leverage ratio is less than or equal to 2.50 to 1.00 but greater than 2.00 to 1.00, the applicable margin is LIBOR plus 2.50% or ABR plus 1.50%; (iv) if the net total leverage ratio is less than or equal to 2.00 to 1.00 but greater than 1.50 to 1.00, the applicable margin is LIBOR plus 2.25% or ABR plus 1.25%; and (v) if the net total leverage ratio is less than or equal to 1.50 to 1.00, the applicable margin is LIBOR plus 2.20% or ABR plus 1.00%. As a result of the Amendment, the applicable LIBOR floor was reduced from 0.50% to 0.00%. From the Amendment No. 1 Effective Date until the fiscal quarter ended December 31, 2020, the interest rate was LIBOR plus 2.50%. For the three months ended March 31, 2021, the interest rate was LIBOR plus 2.25%. For the three months ended June 30, 2021, the interest rate was LIBOR plus 2.25%. Total interest expense relating to the Senior Credit Facilities for the three months ended June 30, 2021 and 2020 was $0.8 million and $0.3 million, respectively, and $3.2 million and $0.3 million for the nine months ended June 30, 2021 and 2020, respectively, reflecting the coupon and accretion of the discount. In addition, the quarterly commitment fee required to be paid based on the unused portion of the revolving facility is subject to a pricing grid based upon the net total leverage ratio as follows (i) if the net total leverage ratio is greater than 3.00 to 1.00, the unused line fee is 0.500%; (ii) if the net total leverage ratio is less than or equal to 3.00 to 1.00 but greater than 2.50 to 1.00, the unused line fee is 0.450%; (iii) if the net total leverage ratio is less than or equal to 2.50 to 1.00 but greater than 2.00 to 1.00, the unused line fee is 0.400%; (iv) if the net total leverage ratio is less than or equal to 2.00 to 1.00 but greater than 1.50 to 1.00, the unused line fee is 0.350%; and (v) if the net total leverage ratio is less than or equal to 1.50 to 1.00, the unused line fee is 0.300%. The Amendment also revised the amount by which we are obligated to make quarterly principal payments. Through the fiscal quarter ending December 31, 2022, we are obligated to make quarterly principal payments in an aggregate amount equal to 1.25% of the original principal amount of the Term Loan Facility. From the fiscal quarter ending March 31, 2023 and for each fiscal quarter thereafter, we are obligated to make quarterly principal payments in an aggregate amount equal to 2.50% of the original principal amount of the Term Loan Facility, with the balance payable at the maturity date thereof. The Credit Agreement contains certain affirmative and negative covenants customary for financings of this type that, among other things, limit our and our subsidiaries’ ability to incur additional indebtedness or liens, to dispose of assets, to make certain fundamental changes, to designate subsidiaries as unrestricted, to make certain investments, to prepay certain indebtedness and to pay dividends, or to make other distributions or redemptions/repurchases, in respect of our and our subsidiaries’ equity interests. In addition, the Credit Agreement contains financial covenants, each tested quarterly, (1) a net secured leveraged ratio of not greater than 3.25 to 1.00; (2) a net total leverage ratio of not greater than 4.25 to 1.00; and (3) minimum liquidity of at least $75 million. The Credit Agreement also contains events of default customary for financings of this type, including certain customary change of control events. As of June 30, 2021, we were in compliance with all Credit Agreement covenants.
