Comprehensive Income and Accumulated Other Comprehensive Income

Note 7. Comprehensive Income and Accumulated Other Comprehensive Income

Comprehensive income was $10.3 million for the three months ended March 31, 2018, compared to $14.5 million for the three months ended March 31, 2017.  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 debt securities.

Comprehensive income includes net income plus unrealized gains (losses) on our available-for-sale debt securities, net of tax. In reporting comprehensive income on a net basis in the statements of comprehensive income, we used a 21 percent tax rate in 2018 and a 35 percent tax rate in 2017. 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.

	Three Months Ended March 31,
	2018			2017
	(in thousands)
Beginning balance	$	3,612		$	(492	)
Other comprehensive income (loss) before    reclassification		(5,634	)		978
Amounts reclassified from accumulated other    comprehensive income		(214	)		(26	)
Net current period other comprehensive    income (loss)		(5,848	)		952
Ending balance	$	(2,236	)	$	460

The sale or other-than-temporary impairment of an available-for-sale security results in amounts being reclassified from accumulated other comprehensive income to current period net income. The effects of reclassifications out of accumulated other comprehensive income by the respective line items of net income are presented in the following table.
