7. | SHORT-TERM BORROWINGS
We established a working capital credit facility with a bank in October 2003 and in the past, renewed the line periodically, with a maximum principal availability of $1.25 million based on qualified receivables. Since we have not borrowed under the bank line of credit in the past five years and did not expect to need to do so in the foreseeable future, when the line of credit expired on June 30, 2016, we did not renew the bank line for an additional period.
