We established a working capital credit facility with a bank in

October

2003

and in the past, renewed the line periodically with the last renewal on

June

27,

2014

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.
