In December 2011, we amended our $15.0 million line of credit agreement with Wells Fargo Bank, N.A. to extend the maturity date to December 1, 2013. Interest on the line of credit is LIBOR plus 1.5 percent. The line of credit is secured by substantially all of our assets and includes certain financial covenants. At December 31, 2011, we had no outstanding borrowings under this agreement and we were in compliance with all of the financial covenants.
