Debt
Debt	Note 9. Debt Prior to 2015, we had an unused credit facility with a bank that provided for a line of credit of $10.0 million. The line of credit was secured by marketable securities we had with the bank at that time. This line of credit was never used and there were no outstanding borrowings under this line of credit as of December 31, 2015 and 2014. This line of credit was terminated in January 2015 when we closed our investment account with this institution and moved all of our funds from this bank to a different bank.
