During the three months endedJune 30, 2016, the Company repurchased 97,500 shares of its common stock at a cost of $3.6 million. All shares repurchased under this program were retired, which resulted in a reduction of $1.0 million in paid-in capital and a reduction of $2.6 million in retained earnings.

The accumulated other comprehensive loss balance at June 30, 2016 and December 31, 2015, and the activity during the six months endedJune 30, 2016, consists of foreign currency translation adjustments.
