Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The condensed consolidated financial statements consist of financial and operating data of DTAG and DTAC, which are both S corporations. Since DTAC and DTAG are flow-through entities for federal income tax purposes, there is no federal income tax expense related to the income of DTAC and DTAG, other than for two of DTAG’s C corporation subsidiaries, one of which is wholly owned with the other majority owned. The taxable income flows through to our shareholders who are responsible for paying the associated taxes. The Company recognizes deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of its assets and liabilities recorded in jurisdictions that either do not recognize the Company's S corporation status and/or assess a tax on the Company's operations at the entity level. The Company's policy is to record a valuation allowance against its deferred tax assets to reduce the net carrying value to an amount that management believes is more likely than not to be realized. As of June 30, 2013, our deferred tax assets and liabilities are immaterial to the financial statements. Although most states follow the federal recognition of S corporation status, some states do impose an entity level tax on that income; therefore, the tax expense is adjusted accordingly. We did not have an income tax liability as of June 30, 2013. Our income tax liability was $0.2 million as of December 31, 2012. At June 30, 2013 and December 31, 2012, the Company had no unrecognized tax benefits. The Company recognizes accrued interest and penalties, if applicable, related to unrecognized tax benefits in income tax expense. The Company had not accrued any amounts related to the payment of interest and penalties as of June 30, 2013 and December 31, 2012.
