Income Tax

Primarily due to the cumulative losses that the Company recorded over the past three years, in 2012, the Company determined that it was more likely than not that it will not be able to utilize its deferred tax assets to offset future taxable income. Therefore, substantially all deferred tax assets are subject to a tax valuation allowance until the Company can establish that the recoverability of its deferred tax assets is more likely than not to be realized. Due to the full tax valuation allowance, no federal income tax benefit was recorded for the three months ended March 31, 2013.

The Company and its subsidiaries are subject to U.S. Federal income tax as well as income tax of multiple state and foreign jurisdictions. As of March 31, 2013, the Company is subject to U.S. Federal income tax examinations for the years 2009 through 2011 and income tax examinations from various other jurisdictions for the years 2006 through 2011. The Company is currently under examination by the Canada Revenue Authority for the years 2006 through 2010 and the Company is complying with the information requests and procedural requirements of the examination.

Earnings from the Company’s foreign subsidiaries are considered to be indefinitely reinvested. A distribution of these non-U.S. earnings in the form of dividends or otherwise would subject the Company to both U.S. Federal and state income taxes, as adjusted for foreign tax credits.
