Revolving Line of Credit

(5) Revolving Line of Credit

On November 16, 2015, we entered into a $300.0 million Credit Agreement with various lender parties and Wells Fargo Bank, National Association, as Administrative Agent (the “Credit Facility”). The Credit Facility provides for a revolving credit line up to $300.0 million, including a $10.0 million sublimit for letters of credit. The Credit Facility matures on November 16, 2020. Borrowings under the Credit Facility may be used for general corporate purposes, including working capital requirements, acquisitions and share repurchases.

Borrowings under the Credit Facility bear interest at a rate of either (1) Wells Fargo Bank’s prime rate (subject to certain higher rate determinations) plus a margin of 0.25% to 1.00% or (2) the 30, 60, 90 or 180 day LIBOR rate plus a margin of 1.25% to 2.00%. As of June 30, 2017, the interest rates were 4.50% under the Wells Fargo Bank's prime rate and 2.37% under a 30-day LIBOR contract. The Credit Facility is secured by substantially all of our assets. The Credit Facility requires us to maintain certain financial ratios and other financial conditions and prohibits us from making certain investments, advances, cash dividends or loans, and limits incurrence of additional indebtedness and liens. As of June 30, 2017, we were in compliance with those covenants.

As of June 30, 2017, we had no outstanding borrowings and two outstanding letters of credit totaling $2.2 million. Available borrowing capacity under the Credit Facility was $297.8 million.
