Debt Disclosure [Abstract]  
Credit Facilities
Our credit agreement provides for a revolving line of credit up to $400 million that may be used for revolving loans, swingline loans (subject to a sublimit of $5 million), and to request letters of credit, subject to a sublimit of $50 million. The line of credit is available for general corporate purposes, including working capital, capital expenditures and acquisitions. Borrowings are permitted in currencies other than the U.S. Dollar. In September 2017, we extended the term of our credit agreement to September 2022, at which time all outstanding borrowings must be repaid. At June 30, 2018, we had no borrowings under the credit agreement.
At June 30, 2018, we held two letters of credit under our credit agreement totaling $0.7 million. Each of these letters of credit may be called by vendors or customers in the event that we default under the terms of a contract, the probability of which we believe is remote. In addition, two letters of credit totaling $3.0 million, secured with restricted cash balances, are held with another financial institution to cover similar obligations to customers.
Our credit agreement requires us to comply with certain financial covenants and other covenants including a maximum total leverage ratio and a minimum fixed charge coverage ratio. It also includes some restrictions on the payment of dividends where our debt exceeds a certain level. We were in compliance with all covenants as of June 30, 2018 and there are no restrictions on our ability to pay dividends.
Derivative Arrangement
In order to add stability to our interest expense and manage our exposure to interest rate movements, we may enter into derivative arrangements to fix payments on part of an outstanding loan balance. We agree to pay a fixed rate of interest to a financial institution and receive a balance equivalent to the floating rate payable. Our outstanding derivative instruments expired during fiscal year 2017. As this cash flow hedge was considered effective, the gains and losses in the fair value of this derivative instrument were reported in accumulated other comprehensive income (AOCI) in the consolidated statement of comprehensive income.
Interest Payments
During the nine months ended June 30, 2018 and 2017, we made interest payments of less than $0.1 million and $1.9 million, respectively.
