Sale Leaseback Transaction, Other Information	In the event that E&S exercises the option to repurchase the property sooner than the end of the 5-year term, the difference between the carrying balance of the debt and the repurchase cost would be recorded as a prepayment premium or discount on the payoff of the debt balance. The cash payment required to repurchase the property on December 31, 2012 was $3,028 consisting of $3,153 repurchase price under the agreement less a credit for the $125 security deposit. Accordingly, if the Company had exercised its option to repurchase the property on December 31, 2013, it would have recorded a prepayment premium of approximately 7% in the amount of $210 over the $2,818 carrying balance of the debt.
