     RESTRICTED SECURITIES AVAILABLE FOR SALE

Restricted securities available for sale consist of amounts held in trusts related to VSC Re.  We determine the appropriate classification of our investments in debt securities at the time of purchase and reevaluate such determinations at each balance sheet date.  Debt securities for which we do not have the intent or ability to hold to maturity are classified as available for sale, and stated at fair value with unrealized gains and losses, net of income taxes included in the determination of comprehensive income and reported as a component of shareholders’ equity.

Restricted securities available for sale consist of the following:
