Line Of Credit Facility [Abstract] |
Line of Credit | 5. Line of Credit On September 1, 2011, the Company executed a new agreement with its consortium of lenders that increased the size of the line of credit facility (the “Line”) from $140,000,000 to $150,000,000. The pricing of the Line, which expires on November 30, 2014, is 300 basis points above 30-day LIBOR (4.00% at March 31, 2013 and March 31, 2012) with a 1% floor on LIBOR. Pledged as collateral for this credit facility are all of the assets of the Company. The outstanding amount of the credit facility was approximately $125,500,000 and $112,000,000 as of March 31, 2013 and March 31, 2012, respectively. The amount available under the line of credit was approximately $24,500,000 and $38,000,000 as of March 31, 2013 and March 31, 2012, respectively. The facility requires compliance with certain financial ratios and covenants and satisfaction of specified financial tests, including maintenance of asset quality and performance tests. Dividends do not require consent in writing by the agent and majority lenders under the new facility as long as the Company is in compliance with a net income covenant. As of March 31, 2013, the Company was in full compliance with all debt covenants.
