Income Tax Disclosure [Abstract]
Income taxes	Income taxes The Company recorded a tax benefit to continuing operations of $1,025,000 for the three and nine months ended September 30, 2016 related to tax rate reductions enacted in the United Kingdom in September 2016 which resulted in a decrease in the Company's deferred tax liability. Intraperiod tax allocation rules require the Company to allocate the provision for income taxes between continuing operations and other categories of earnings, such as discontinued operations. In periods in which the Company has a year-to-date pre-tax loss from continuing operations and pre-tax income in other categories of earnings, such as discontinued operations, the Company must allocate the tax provision to the other categories of earnings, and then record a related tax benefit in continuing operations. During the three and nine months ended September 30, 2016, the Company recognized net losses from both continuing and discontinued operations, and therefore no allocation of income tax was required. During the three and nine months ended September 30, 2015 the Company recognized net income from discontinued operations, and, as a result, recorded income tax expense of $2,520,000 and $15,998,000, respectively, which is included in net income (loss) from discontinued operations in the condensed consolidated statement of operations and comprehensive income (loss). Accordingly, the Company recognized a related income tax benefit of $5,496,000 and $12,428,000 from continuing operations in the condensed consolidated statement of operations and comprehensive income (loss) for the three and nine months ended September 30, 2015, respectively. The remaining $3,535,000 income tax benefit to continuing operations was recognized throughout the remainder of 2015.
