Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes. Our overall effective tax rate for the three months ended March 31, 2015 and 2014 was 30.7% and 27.4%, respectively, which resulted in a provision for income taxes of $2.3 million and $1.1 million, respectively. The increase in the effective income tax rate for the first quarter of 2015, when compared to the first quarter of 2014, was due primarily to the increased profit of our U.S. operations, which are generally taxed at a higher rate than our foreign operations.

The entire disclosure for income taxes.
