Note 4—Investments
Investments in fixed maturity securities are classified as available-for-sale. The primary objectives of our investment portfolio are to maintain the safety of our invested capital, provide prudent levels of liquidity to accommodate operational and capital needs and maintain an acceptable level of risk. These risks include credit risk, interest rate risk and concentration risk, which are mitigated through the use of various well-established financial institutions as well as an investments portfolio consisting of very liquid and high credit quality instruments.
The following table summarizes our investments, available-for-sale:
