Debt financing	$ 8,600,000
Line of credit	$ 1,000,000
Subsequent events, description	The debt is comprised of a $5,100,000 mortgage note that bears interest at a fixed rate of 3.50% per annum (with a 10-year term and 25-year amortization schedule) and a $3,500,000 note that bears interest at a fixed rate of 3.50% per annum (with a 7-year term and amortization schedule). The line of credit bears interest at a variable rate equal to the one (1) month LIBOR plus 2.15% per annum. The proceeds were used to repay all bank debt outstanding at the time of closing (see Note 11) and to provide some additional working capital. We were required by a bank debt covenant (before the debt refinancing discussed above) to maintain at least $2 million of otherwise unrestricted cash, cash equivalents and short-term investments. Under the new debt, we are required to hold $1.4 million in escrow (a non-current asset), which reduces the effective availability of our liquid assets for operational needs by that amount.
