Note 7.  Bank Line of Credit

As of December 31, 2015, we have access to a $100 million bank revolving line of credit with a $25 million letter of credit sublimit that expires on November 3, 2020. As of December 31, 2015, a total of $98.2 million available under the facility due to $1.8 million outstanding letters of credit, which reduce the availability for letters of credit to $23.2 million.  We had no borrowings outstanding on our line of credit as of December 31, 2015. Bonds with a fair value of $109.0 million were pledged as collateral on the line at December 31, 2015. The securities pledged as collateral have no trading restrictions and are reported as available-for-sale securities in the Statements of Financial Position as of December 31, 2015.  The banks require compliance with certain covenants, which include leverage ratios, for our line of credit.  We are in compliance with all covenants at December 31, 2015.
