Income Taxes	10. Income Taxes The Company has determined its interim tax provision projecting an estimated annual effective tax rate. For the three- and six-months ended June 30, 2013, the Company recorded income tax expense of $0.1 million and $0.3 million, respectively, yielding an effective tax rate of 0.4% and 0.9%, respectively. The effective tax rate differs from the U.S. statutory rate of 34% in the periods ended June 30, 2013 and 2012, primarily due to the impact of recording a valuation allowance against the benefits of the current period’s loss. The Company has a valuation allowance of $12.7 million as of June 30, 2013 on the deferred tax assets generated for federal, state and foreign net operating losses where it is not more likely than not that the deferred tax assets will be utilized. In evaluating the Company’s ability to realize its deferred income tax assets, the Company considers all available positive and negative evidence, including operating results, ongoing tax planning, and forecasts of future taxable income on a jurisdiction by jurisdiction basis. The valuation allowance as of June 30, 2013 relates primarily to domestic net operating loss and credit carryforwards that will reduce the provision for income taxes if and when recognized. In general, it is the practice and intention of the Company to reinvest the earnings of its non-U.S. subsidiaries in those operations. As of June 30, 2013, the Company has not made a provision for U.S. or additional foreign withholding taxes for financial reporting over the tax basis of investments in foreign subsidiaries that are essentially permanent in duration, if any exists. Generally, such amounts become subject to U.S. taxation upon the remittance of dividends and under certain other circumstances. It is not practicable to estimate the amount of deferred tax liability related to investments in these foreign subsidiaries.
