Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes. Our overall effective tax rate for the three months ended June 30, 2016 and 2015 was 26.1% and 29.7%, respectively, which resulted in a provision for income taxes of $2.6 million and $3.1 million, respectively. Our overall effective tax rate for the six months ended June 30, 2016 and 2015 was 26.2% and 30.1%, respectively, which resulted in a provision for income taxes of $4.1 million and $5.4 million, respectively. The decrease in the effective income tax rate for both periods, when compared to the prior year periods, was due primarily to the reinstatement of the federal research and development credit and a higher mix of earnings from our foreign operations, which are generally taxed at lower rates than our U.S. operations.
