 2016 Senior Secured Notes
On June 24, 2016, the Company issued two series of senior secured notes with an aggregate total principal balance of $115.0 million at a blended interest rate of 4.55%. Series A carries a principal balance of $28.8 million and bears an interest rate of 4.38% over a twelve-year term, with the principal payment due on June 15, 2028. Series B carries a principal balance of $86.3 million and bears an interest rate of 4.58% over a 20-year term. Series B is interest only for the first five years, with $1.9 million principal payments paid semiannually thereafter. The proceeds of the senior secured notes were primarily used to refinance the previously outstanding long-term tax exempt bonds, which were subject to an early redemption option at 103%, plus accrued interest, as a result of the U.S. IPO. As part of the refinancing of the long-term debt, the Company paid a prepayment penalty of $3.2 million and wrote off the remaining $2.2 million in capitalized loan fees related to the tax exempt bonds, which were recorded as additional interest expense in the second quarter of 2016. The senior secured notes are collateralized by a security interest in the Company’s equity interest in its subsidiaries, including all payments representing profits and qualifying distributions. Debt issuance costs as of both December 31, 2019 and December 31, 2018 were $0.6 million.
The senior secured notes require the Company to maintain a debt service coverage ratio of consolidated EBITDA to consolidated debt service of at least 1.10 to 1.00. Consolidated EBITDA is calculated as net income plus depreciation, taxes, interest and other non-cash charges net of non-cash income. Consolidated debt service is calculated as interest expense, principal payments, and dividend or stock repurchases. The senior secured notes also contain a provision limiting the payment of dividends if the Company falls below a debt service ratio of 1.25. However, for the quarter ending June 30, 2021 through the quarter ending March 31, 2024, the ratio drops to 1.20. As of December 31, 2019, the Company was in compliance with its financial debt covenants.
Eagletail Loans
In May 2017, the Company acquired Eagletail Water Company ("Eagletail"). As part of the acquisition, the Company assumed two unsecured loans held by Eagletail. These loans are payable to the Water Infrastructure Finance Authority of Arizona ("WIFA") and Harquahala Valley Community Benefits Foundation ("Harquahala"). The WIFA loan bears an interest rate of 1.20% over a 20-year term, while the Harquahala loan bears an interest rate of 4.65% over a 15-year term. The Company paid off the WIFA loan in March 2019.
In 2017, the Company entered into a second loan payable to WIFA ("2017 WIFA"), and no borrowings were made until 2018. The 2017 WIFA loan bears an interest rate of 4.60% over a 20-year term. The original loan amount was approximately $175,000, of which approximately $157,000 was forgiven.
Revolving Credit Line
On April 20, 2018, the Company entered into an agreement with MidFirst Bank, a federally chartered savings association, for a two-year revolving line of credit up to $8.0 million, set to expire on April 30, 2020. The credit facility bears an interest rate of LIBOR plus 2.25%. Unamortized debt issuance costs as of December 31, 2019 and December 31, 2018 were $49,000 and $137,000, respectively. In April 2019, the Company signed an amendment which extends the maturity of the line of credit to April 30, 2022 and modifies the debt service coverage ratio to match the ratio required by the senior secured notes discussed above; all other terms remain unchanged. As of December 31, 2019, we had no outstanding borrowings under this credit line.

The revolving credit line requires the Company to maintain a debt service coverage ratio of consolidated EBITDA to consolidated debt service of at least 1.10 to 1.00. The revolving credit line also contains a provision limiting the payment of dividends if the Company falls below a debt service ratio of 1.25. As of December 31, 2019, the Company was in compliance with its financial debt covenant.
