Bank line of credit

As of September 30, 2019, we have access to a $100 million bank revolving line of credit with a $25 million letter of credit sublimit that expires on October 30, 2023. As of September 30, 2019, a total of $99.1 million remains available under the facility due to $0.9 million outstanding letters of credit, which reduce the availability for letters of credit to $24.1 million. We had no borrowings outstanding on our line of credit as of September 30, 2019. Investments with a fair value of $109.8 million were pledged as collateral on the line at September 30, 2019. The investments pledged as collateral have no trading restrictions and are reported as cash and cash equivalents and available-for-sale securities in the Statements of Financial Position as of September 30, 2019. The banks require compliance with certain covenants, which include leverage ratios and debt restrictions, for our line of credit. We are in compliance with all covenants at September 30, 2019.

Term loan credit facility

In 2016, we entered into a credit agreement for a $100 million senior secured draw term loan credit facility ("Credit Facility") for the acquisition of real property and construction of an office building that will serve as part of our principal headquarters. On January 1, 2019, the Credit Facility converted to a fully-amortized term loan with monthly payments of principal and interest at a fixed rate of 4.35% over a period of 28 years. Investments with a fair value of $112.0 million were pledged as collateral for the facility and are reported as cash and cash equivalents and available-for-sale securities in the Statements of Financial Position as of September 30, 2019. The bank requires compliance with certain covenants, which include leverage ratios, debt restrictions and minimum net worth, for our Credit Facility. We are in compliance with all covenants at September 30, 2019.

The remaining unpaid balance from the Credit Facility is reported at carrying value on our Statements of Financial Position, net of unamortized loan origination and commitment fees. See Note 5, "Fair Value" for the estimated fair value of these borrowings.
