Restricted Cash	NOTE C – RESTRICTED CASH As required by the original mortgage loan entered into with Fifth Third Bank (the “Bank”) on July 11, 2008, $500,000 was deposited into an interest-bearing account from which principal and interest payments are made. This mortgage loan has since been extended to July 2016. As extended, the new loan called for a restricted cash balance of $400,000 to be funded annually for principal and interest payments (see NOTE K). The balance in the restricted cash account was held as additional collateral by the Bank and was not available for operations. This loan was settled in full in December 2015 and the balance of restricted cash at December 31, 2015, is zero. During May 2014, we entered into a $10.0 million project loan facility with the Bank (see NOTE K). Per the agreement, we deposited, from the loan proceeds, $500,000 into a restricted bank account to cover principal and interest payments. This account balance was also pledged as additional security for the loan. This loan was amended in 2015 to have a maturity date of December 17, 2015. This loan was satisfied in full before the maturity date in December 2015 and the balance in this account at December 31, 2015, is zero.
