Comprehensive Income and Accumulated Other Comprehensive Income | Note 6. Comprehensive Income and Accumulated Other Comprehensive Income Comprehensive income was $16.2 million for the three months ended September 30, 2016, compared to $19.2 million for the three months ended September 30, 2015. Comprehensive income was $62.8 million for the nine months ended September 30, 2016, compared to $47.9 million for the same period in 2015. The difference between net income as reported and comprehensive income was due to changes in unrealized gains and losses, net of tax on available-for-sale securities. Comprehensive income includes net income plus unrealized gains (losses) on our available-for-sale investment securities, net of tax. In reporting comprehensive income on a net basis in the statement of income, we used a 35 percent tax rate. The following table illustrates the changes in the balance of each component of accumulated other comprehensive income for each period presented in the interim financial statements.

The effects of reclassifications out of accumulated other comprehensive income by the respective line items of net income are presented in the following table.
