Income Tax	3 Months Ended
Mar. 31, 2016
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Primarily due to the cumulative losses that the Company has incurred over the past three years, the Company has determined that there is insufficient positive evidence to conclude that it is more likely than not that it will be able to utilize its deferred tax assets to offset future taxable income. Therefore, substantially all deferred tax assets are currently subject to a tax valuation allowance. However, sufficient evidence may become available in future periods regarding the utilization of deferred tax assets that would lead to the reduction of all or a portion of the valuation allowance resulting in a decrease to income tax expense for the period in which the reduction is recorded. Although the Company is in this full tax valuation allowance position, a tax expense of $0.1 million for both the three months ended March 31, 2016 and 2015 was primarily due to state taxes and reserves for uncertain tax positions. 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, 2016, the Company is subject to U.S. Federal income tax examinations for the years 2012 through 2014 and income tax examinations from various other jurisdictions for the years 2006 through 2014. The Company is also subject to an examination by the Canada Revenue Authority ("CRA") for the years 2006 through 2010. The CRA examination was completed during May 2013 and resulted in proposed adjustments which amount to $1.3 million of additional tax for the 2008 and 2009 tax years. The Company did not agree with these adjustments and filed a request with Competent Authority programs in both the U.S. and Canada in October 2013. The Competent Authority program assists taxpayers with respect to matters covered in the mutual agreement procedure provisions of tax treaties. In the fourth quarter of 2015, Competent Authority completed their review and communicated to the Company that they proposed to assess a tax on the 2009 tax year only.A formal letter of disposition from Competent Authority is expected to be received in 2016. The Company plans to accept the proposal and recorded an expense of approximately $0.8 million in Canada in the fourth quarter of 2015 and expects to realize a related benefit of $0.5 million in the U.S. Earnings from the Company’s foreign subsidiary 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. During the first quarter of 2016, as the result of a small acquisition, the Company recorded $1.3 million of tax deductible goodwill that may result in a tax benefit in future periods.
