5.	Long-Term Debt

We have a $30.0 million revolving credit facility which expires in June 2017. Borrowings under the facility are on an unsecured basis with interest rates ranging from LIBOR plus 65 basis points to LIBOR plus 250 basis points based upon the achievement of certain benchmarks related to the ratio of funded debt to EBITDA, as defined by our credit agreement. The interest rate at December 31, 2016 was LIBOR plus 65 basis points (1.42%). There were no borrowings under the facility as of December 31, 2016. As of December 31, 2016, we had two outstanding letters of credit for approximately $1.0 million in the aggregate which were issued to secure ordinary course of business transactions. Net of these letters of credit, we had approximately $29.0 million available under the facility at December 31, 2016. The credit agreement also contains covenants, the most restrictive of which pertain to net worth and the ratio of debt to EBITDA. As of December 31, 2016, we were in compliance with all financial covenants contained in the revolving credit facility.
