The commercial credit agreement provides for (i) an October 1, 2015 maturity date; (ii) interest rate provisions such that the margin on loans bears interest at the reference rate minus 0.25% or LIBOR plus 1.50%; and (iii) financial covenants requiring a minimum quick ratio, tangible net worth and net profit after tax. We are in compliance with all loan covenants at August 31, 2012. We do not currently have any outstanding loan balance under the commercial credit agreement.
