As discussed in Note 5, the Company has in place a bank credit agreement that includes a $150 million five-year term loan and a $220 million seven-year term loan. The loans require no amortization and are prepayable without penalty prior to maturity. Under the credit agreement, both term loans bear interest at variable rates plus a margin based on the Company's credit measures. However, following closing on the loans, the Company entered into receive-floating / pay-fixed interest rate swap agreements that convert the variable benchmark rate on both loans to a fixed rate over their full terms to maturity. With the swap agreements in place, the effective interest rate on the $150 million five-year loan and the $220 million seven-year loan were 2.94% and 3.48%, respectively, at March 31, 2018 and 2017. The effective rates will change only if a change in the Company's credit measures results in adjustments to the applicable credit spreads specified in the underlying loan agreement. The $150 million five-year term loan matures in fiscal year 2020, and the $220 million seven-year term loan matures in fiscal year 2022.

In November 2017, the Company filed an undenominated universal shelf registration statement with the U.S. Securities and Exchange Commission to provide for the future issuance of an undefined amount of additional debt or equity securities as determined by the Company and offered in one or more prospectus supplements prior to issuance.
