In June 2019, the Company refinanced its senior unsecured credit facility (“the Facility”), increasing borrowing capacity from $700 million to $1 billion. The Facility matures in June 2024. The current interest rate for the Facility is LIBOR + 1.0%. The interest rate ranges from LIBOR + 0.875% to a maximum of LIBOR + 1.50%, depending upon the better of the Company’s leverage ratio or the credit rating. As of March 31, 2020, total borrowings under the Facility were $693 million, which approximates fair value. The Facility agreement permits us to issue letters of credit up to an aggregate amount of $50 million. Outstanding letters of credit reduce the amount available for borrowing under the Facility. As of March 31, 2020, there were no issued letters of credit under the Facility, resulting in undrawn availability under the Facility of $307 million. The weighted average interest rate for the Facility was 2.88% for the three months ended March 31, 2020.

The Facility agreement contains financial and other covenants, including, but not limited to customary restrictions on the incurrence of debt by our subsidiaries and the granting of liens, as well as the maintenance of an interest coverage ratio and a leverage ratio. As defined in the Facility agreement, we are required to maintain a minimum interest coverage ratio of 3.50 (based on the ratio of EBITDA to interest expense) and may not exceed a maximum leverage ratio of 3.75 (based on the ratio of total debt to EBITDA) with a step up to 4.25 allowed following certain acquisitions. In addition, the Facility agreement contains other customary terms and conditions such as representations and warranties, additional covenants and events of default.

In 2017, the Company issued $400 million in aggregate principal amount of 3.95% Senior Unsecured Notes due in 2027. The interest rate on these senior notes may be increased 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 5.95%. The effective interest rate for three months ended March 31, 2020 was 3.87% inclusive of approximately a 0.25% benefit of treasury locks. Based on quoted prices the fair value of the senior unsecured notes due in 2027 was $408.3 million at March 31, 2020.

In January 2020 we used $49.9 million to repay and terminate the Euro term loan.

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, 2020 was 4.83%. Based on quoted prices, the fair value of these notes was $346.0 million at March 31, 2020.
