Income Tax Disclosure [Abstract]
Income Taxes	The Company accounts for income taxes using the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. Deferred tax assets are reduced by a valuation allowance if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Management continues to review the level of the valuation allowance on a quarterly basis. There can be no assurance that the Company's future operations will produce sufficient earnings to allow for the deferred tax asset to be fully utilized. The Company currently maintains a full valuation allowance against net deferred tax assets. Each year the Company files income tax returns in the various national, state and local income taxing jurisdictions in which it operates. These tax returns are subject to examination and possible challenge by the taxing authorities. Positions challenged by the taxing authorities may be settled or appealed by the Company. As a result, there is an uncertainty in income taxes recognized in the Company's consolidated financial statements in accordance with ASC Topic 740. The Company applies this guidance by defining criteria that an individual income tax position must meet for any part of the benefit of that position to be recognized in an enterprise's financial statements and provides guidance on measurement, de-recognition, classification, accounting for interest and penalties, accounting in interim periods, disclosure, and transition. Other long-term liabilities related to income tax contingencies were $0 as of February 28, 2021 and $0 as of May 31, 2020. Interest and penalties associated with uncertain tax positions are recognized as components of the "Provision for income taxes." The liability for payment of interest and penalties was $0 as of February 28, 2021 and May 31, 2020. Several tax years are subject to examination by major tax jurisdictions. In the United States, federal tax years ended May 31, 2017 and after are subject to examination. Effective Tax Rate The effective tax rate was (0.1%) and (15.4%) for the three and nine months ended February 28, 2021 respectively. The effective tax rate on consolidated net income for the three and nine months ended February 28, 2021 and February 29, 2020 differs from the federal statutory tax rate primarily due to changes in the deferred tax valuation allowance, tax benefit recorded related to the bargain purchase gain and the impact of certain expenses not being deductible for income tax reporting purposes.

The Company accounts for income taxes using the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. Deferred tax assets are reduced by a valuation allowance if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Management continues to review the level of the valuation allowance on a quarterly basis. There can be no assurance that the Company's future operations will produce sufficient earnings to allow for the deferred tax asset to be fully utilized. The Company currently maintains a full valuation allowance against net deferred tax assets.

Each year the Company files income tax returns in the various national, state and local income taxing jurisdictions in which it operates. These tax returns are subject to examination and possible challenge by the taxing authorities. Positions challenged by the taxing authorities may be settled or appealed by the Company. As a result, there is an uncertainty in income taxes recognized in the Company's consolidated financial statements in accordance with ASC Topic 740. The Company applies this guidance by defining criteria that an individual income tax position must meet for any part of the benefit of that position to be recognized in an enterprise's financial statements and provides guidance on measurement, de-recognition, classification, accounting for interest and penalties, accounting in interim periods, disclosure, and transition.

Other long-term liabilities related to income tax contingencies were $0 as of February 28, 2021 and $0 as of May 31, 2020. Interest and penalties associated with uncertain tax positions are recognized as components of the "Provision for income taxes." The liability for payment of interest and penalties was $0 as of February 28, 2021 and May 31, 2020.

Several tax years are subject to examination by major tax jurisdictions. In the United States, federal tax years ended May 31, 2017 and after are subject to examination.

Effective Tax Rate

The effective tax rate on consolidated net income for the three and nine months ended February 28, 2021 and February 29, 2020 differs from the federal statutory tax rate primarily due to changes in the deferred tax valuation allowance, tax benefit recorded related to the bargain purchase gain and the impact of certain expenses not being deductible for income tax reporting purposes.
