Debt Disclosure [Abstract] |
Revolving Line of Credit | REVOLVING LINE OF CREDIT On November 16, 2015, we entered into a $300.0 million Credit Agreement (the “Credit Facility”) with the various lenders party thereto and Wells Fargo Bank, National Association, as Administrative Agent. The Credit Facility provides for a revolving credit line of 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 December 31, 2017, our interest rate was 4.75% under the prime rate option or approximately 2.78% under the 30-day LIBOR option. The Credit Facility is secured by substantially all 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 December 31, 2017, we were in compliance with those covenants. As of December 31, 2017, we had no outstanding borrowings and had unused borrowing capacity of $299.5 million under the Credit Facility. In addition, as of December 31, 2017, we had one outstanding letter of credit for $0.5 million in favor of a client contract. The letter of credit guarantees our performance under the contract and expires in 2018. We paid interest of $804,000 in 2017, $1.9 million in 2016, and $223,000 in 2015.
