Accumulated Other Comprehensive Loss
Accumulated Other Comprehensive Loss
 
Accumulated other comprehensive loss consists of the actuarial loss on the defined benefit pension plan, net of tax, and unrealized gains on available-for-sale marketable securities, as reported within the Consolidated Statement of Stockholders’ Equity. Changes in accumulated other comprehensive loss were reported as “Other comprehensive (loss) income, net” within the Consolidated Statements of Comprehensive Income. There were no reclassification adjustments, which represent realized gains or losses on the sales of available-for-sale marketable securities included in net income, for the three- and six-month periods ended June 30, 2015, compared to gains of $124,000 and $172,000 for the three- and six-month periods ended June 30, 2014, respectively.

The following table summarizes the components of other comprehensive (loss) income for the three- and six-month periods presented:
