Income Taxes [Abstract]
Income Taxes	10. Income Taxes The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. The Internal Revenue Service (the "IRS") has completed examinations of the Company's U.S. income tax returns or the statute of limitations has passed on returns for the years through 2009. The Company's 2011 U.S. income tax return is currently under examination by the IRS. Under the provisions of the ASC Subtopic 740-10-25, Income Taxes - Recognition, the Company had an unrecognized tax benefit of $0.5 million as of March 31, 2014. The Company's effective tax rate was 42.3% for the three months ended March 31, 2014 compared to 21.5% for the three months ended March 31, 2013. The increase in the effective rate is primarily due to the expiration of the research and development tax credit, which has not been re-enacted by Congress for 2014. In addition to the research and development tax credit and U.S. domestic production deduction, the difference between the Company's federal statutory rate of 35% and the effective tax rate relates primarily to state income taxes, net of the federal benefit, and permanent non-deductible items such as non-deductible executive compensation, 50% of meals and entertainment expenses, and transaction costs. As of March 31, 2014, the Company's net current deferred tax asset was $0.1 million and its net non-current deferred tax liability was $9.7 million. Generally, deferred tax assets are related to stock compensation, accruals and net operating losses of acquired companies. Deferred tax liabilities relate to goodwill, intangibles, fixed asset depreciation, and prepaid expenses. Net current deferred tax assets are recorded in "Other current assets" and net non-current deferred tax liabilities are recorded in "Other non-current liabilities" on the Condensed Consolidated Balance Sheet as of March 31, 2014.
