Our investments and a portion of our cash equivalents are managed by professional portfolio managers operating under documented investment guidelines. Our portfolio managers must obtain our prior approval before selling investments where the loss position of those investments exceeds certain levels. Our investments consist primarily of investment-grade debt securities with a maximum maturity of </font><font style="font-family:Arial;font-size:10pt;">10</font><font style="font-family:Arial;font-size:10pt;"> years and an average duration of </font><font style="font-family:Arial;font-size:10pt;">three</font><font style="font-family:Arial;font-size:10pt;"> years or less. Restricted investments are invested principally in certificates of deposit and U.S. treasury securities. Concentration of credit risk with respect to accounts receivable is limited because our payors consist principally of the governments of each state in which our health plan subsidiaries operate.</font></div></div>
