The Company’s Senior Credit Facility matures on May 8, 2020 and provides a $600 million revolver, an amortizing term loan and a $450 million expansion option, subject to certain conditions. Borrowings are subject to a pricing grid, which can result in increases or decreases to the borrowing spread, depending on the Company’s leverage ratio, ranging from 1.00% to 2.25% in the case of loans bearing interest at LIBOR and from 0.00% to 1.25% in the case of loans bearing interest at the base rate. As of May 31, 2018, the borrowing spread on LIBOR based borrowings was 2.00% (aggregating to a 4.00% variable rate borrowing cost on the outstanding term loan balance). In addition, a non-use fee is payable quarterly on the average unused credit line under the revolver ranging from 0.15% to 0.35% per annum. As of May 31, 2018, the unused credit line under the revolver was $598.3 million, of which $146.1 million was available for borrowing. Quarterly term loan principal payments of $3.8 million began on June 30, 2016, increased to $7.5 million starting on June 30, 2017 and extend through March 31, 2020, with the remaining principal due at maturity. The Senior Credit Facility, which is secured by substantially all of the Company’s domestic personal property assets, also contains customary limits and restrictions concerning investments, sales of assets, liens on assets, dividends and other payments. The two financial covenants included in the Senior Credit Facility agreement are a maximum leverage ratio of 3.75:1 and a minimum interest coverage ratio of 3.5:1. The Company was in compliance with all financial covenants at May 31, 2018.

Subsequent to quarter-end (June 22, 2018) and pursuant to the provisions of the Senior Credit Facility, the Company reduced the borrowing capacity on the revolver from $600 million to $300 million. The amount available for borrowing under the revolver was not impacted by the June 2018 reduction in borrowing capacity. This reduction in borrowing capacity is expected to reduce the non-use fee on the average unused credit line under the revolver. The Company estimates a charge of $1.0 million in the fourth quarter of fiscal 2018 for the write-off of deferred financing costs associated with the reduced borrowing capacity.

On April 16, 2012, the Company issued $300 million of 5.625% Senior Notes due 2022 (the “Senior Notes”), of which $287.6 million remains outstanding. The Senior Notes require no principal installments prior to their June 15, 2022 maturity, require semiannual interest payments in December and June of each year and contain certain financial and non-financial covenants. The Senior Notes include a call feature that allows the Company to repurchase them anytime on or after June 15, 2017 at stated redemption prices (ranging from 100.0% to 102.8%), plus accrued and unpaid interest. The Company repurchased $0.5 million of Senior Notes at a redemption price of 103% in the three months ended May 31, 2017. The Company was in compliance with all the terms of the Senior Notes at May 31, 2018.
