Interest rates The Revolving Facility had an effective interest rate of 2.68% and 5.52% as of December 31, 2015 and 2016, respectively. The Senior Notes carry an interest rate of 6.375%. The Senior Subordinated Notes had an implied rate of 7.00%. On August 11, 2015, we prepaid our Senior Subordinated Notes (see Note 7 "Debt and Liquidity"). This prepayment resulted in accelerated amortization of $4.5 million as the Notes were prepaid at the face value. The accelerated expense was recorded in the predecessor period.
