8.	Bank Credit Arrangements

In March 2016, the Company entered into a $60,000 five-year term loan with a commercial bank. The term loan requires quarterly principal and interest payments, with interest at a variable rate tied to LIBOR, and a balloon principal payment due March 31, 2021. The required principal payments on the term loan for each of the remaining fiscal years are as follows: remainder of fiscal 2019 – $4,125, fiscal 2020 – $6,000, and fiscal 2021 – $39,000. In light of the term loan’s interest being determined on a variable rate basis, the fair value of the term loan at December 31, 2018 approximates the current carrying value reflected in the accompanying Condensed Consolidated Balance Sheet.

In order to limit exposure to volatility in the LIBOR interest rate, the Company and the commercial bank also entered into an interest rate swap that effectively converts the variable interest rate on the term loan to a fixed rate of 2.76%. With an initial notional balance of $60,000, the interest rate swap was established with critical terms identical to those of the term loan, including: (i) notional reduction amounts and dates; (ii) LIBOR settlement rates; (iii) rate reset dates; and (iv) term/maturity. Due to this, the interest rate swap has been designated as an effective cash flow hedge, with changes in fair value reflected as a separate component of other comprehensive income in the accompanying Condensed Consolidated Statements of Comprehensive Income. At December 31, 2018 and September 30, 2018, the fair value of the interest rate swap was $1,145 and $1,722, respectively, and is reflected as a non-current asset in the accompanying Condensed Consolidated Balance Sheets. This fair value was determined by information provided by the counterparty, and is considered a Level 2 input within the fair value hierarchy of valuation techniques.

In addition, the Company maintains a $30,000 revolving credit facility with a commercial bank, which expires March 31, 2021. There were no borrowings outstanding on this credit facility at December 31, 2018 or September 30, 2018.

The term loan and the revolving credit facility are collateralized by the business assets of the Company’s U.S. subsidiaries and require compliance with financial covenants that limit the amount of debt obligations and require a minimum level of coverage of fixed charges, as defined in the borrowing agreement. As of December 31, 2018, the Company is in compliance with all covenants. The Company is also required to maintain a compensating cash balance with the bank in the amount of $1,000, and is in compliance with this requirement.
