Note 6. Comprehensive Income

Comprehensive income was $9.5 million for the three months ended March 31, 2012, compared to $6.5 million for the three months ended March 31, 2011. The difference between net income as reported and comprehensive income was due to changes in unrealized gains and losses, net of tax.
