The effective interest rate for three months ended March 31, 2019 was 3.88% inclusive of approximately a 0.25% benefit of treasury locks. Based on quoted prices the fair value of the senior notes due in 2027 was $400.3 million at March 31, 2019.

In 2015, the Company issued $300 million in aggregate principal amount of 4.7% Senior Unsecured Notes due in 2025. The interest rate on these senior notes may be increased by 0.25% each time a credit rating applicable to the notes is downgraded. Conversely, such increases would be reversed should the credit rating be subsequently upgraded. The maximum rate is 6.7%. The effective interest rate for the three months ended March 31, 2019 was 4.83%. Based on quoted prices, the fair value of the notes due in 2025 was $314.1 million at March 31, 2019.

The Company has a revolving credit facility (the “Facility”) that allows up to $700 million of borrowings. The Facility matures in June 2021. The interest rate for the Facility at March 31, 2019 was LIBOR + 1.25%. The interest rate ranges from LIBOR + 0.875% to a maximum of LIBOR + 1.875%, depending on the Company’s leverage ratio.

The Facility contains financial and other covenants, including, but not limited to, restrictions on the incurrence of debt and the granting of liens, as well as the maintenance of an interest coverage ratio and a leverage ratio. In accordance with the terms of the Facility, we are required to maintain a minimum interest coverage ratio of 3.50 (based on the ratio of EBITDA, as defined in the Facility Agreement, to interest expense) and may not exceed a maximum leverage ratio of 3.50 (based on the ratio of total debt to EBITDA) throughout the term of the Facility. In addition, the Facility contains other terms and conditions such as customary representations and warranties, additional covenants and customary events of default.

As of March 31, 2019, total borrowings under the Facility were $414.0 million, which approximates fair value due to its revolving nature. The Facility permits us to issue letters of credit up to an aggregate amount of $40 million. Outstanding letters of credit reduce the amount available for borrowing under our Facility. As of March 31, 2019, there were no outstanding letters of credit under the Facility, resulting in undrawn availability under the Facility as of March 31, 2019 of $286.0 million. The weighted average interest rate for the Facility was 4.17% for the three months ended March 31, 2019.

In 2016, we entered into a €60 million term loan. The loan has two tranches of which the first tranche for €25 million has a rate of Euribor +1.2% and a final maturity date of June 30, 2023, and a second tranche for €35 million has a rate of Euribor +1.25% with a final maturity date of June 30, 2024. The loans are payable in annual installments that began on June 30, 2017, for the first tranche, and beginning on June 30, 2019, for the second. There is a zero percent floor on the Euribor. Amounts outstanding under this loan at March 31, 2019 were $59.4 million which approximates fair value under the market approach.
