Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s corporate structure requires the filing of two separate consolidated U.S. Federal income tax returns and one Canadian income tax return which include Lynden US, Earthstone, and Lynden Corp. As such, taxable income of Earthstone cannot be offset by tax attributes, including net operating losses, of Lynden US, nor can taxable income of Lynden US be offset by tax attributes of Earthstone. Earthstone and Lynden US record a tax provision, respectively, for their share of the book income or loss of EEH, net of the non-controlling interest. As EEH is treated as a partnership for U.S. Federal income tax purposes, it is not subject to income tax at the federal level and only recognizes the Texas Margin Tax. As of March 31, 2021 and December 31, 2020, a current liability of $0.9 million and $0.6 million, respectively, is included in Other current liabilities in the Condensed Consolidated Balance Sheets. The amounts represent the 2020 Texas Margin Tax payable in June 2021. The additional $0.3 million recorded in 2021 is IRM’s 2020 Texas Margin Tax liability acquired in the IRM Acquisition. During the three months ended March 31, 2021, the Company recorded income tax expense of approximately $0.3 million which included (1) a deferred income tax benefit for Lynden US of $0.2 million as a result of its share of the distributable income from EEH, (2) no net income tax benefit for Earthstone as the $1.2 million income tax benefit resulting from its share of the distributable loss from EEH had a full valuation allowance recorded against it as future realization of the net deferred tax asset cannot be assured and (3) deferred income tax benefit of $0.1 million related to the Texas Margin Tax. Lynden Corp incurred no material income or loss, or related income tax expense or benefit, for the three months ended March 31, 2021. During the three months ended March 31, 2020, the Company recorded income tax expense of approximately $1.1 million which included (1) income tax expense for Lynden US of $0.7 million as a result of its share of the distributable income from EEH, (2) deferred income tax expense for Earthstone of $2.9 million as a result of its share of the distributable income from EEH, which was used to reduce the valuation allowance recorded against its deferred tax asset which was previously recorded as future realization of the net deferred tax asset cannot be assured and (3) deferred income tax expense of $0.4 million related to the Texas Margin Tax. Lynden Corp incurred no material income or loss, or related income tax expense or benefit, for the three months ended March 31, 2020.
