(6) Short-Term Borrowings

We have a $50,000,000 Financing and Security Agreement (the “Credit Agreement”) with a bank that expires on October 31, 2014 and is secured by certain of our assets. The Credit Agreement contains a provision to increase the maximum principal amount to $75,000,000 upon lender approval. The maximum interest rate on the Credit Agreement is the daily LIBOR market index rate plus 2.25%. Based upon our financial performance, the interest rate can be reduced. The Credit Agreement contains covenants with respect to our minimum tangible net worth, total liabilities to tangible net worth ratio and cash flow to debt service ratio. We were in compliance with all loan covenants under the Credit Agreement as of December 31, 2012. As of December 31, 2012, there were no borrowings outstanding and $50,000,000 of available borrowings under the Credit Agreement.
