The Company regularly evaluates estimates and assumptions related to allowances for doubtful accounts, inventory valuation and standard cost allocations, valuation of initial right-of-use assets and corresponding lease liabilities, valuation of beneficial conversion features in convertible debt, valuation of the assets and liabilities of discontinued operations, stock-based compensation expense, purchased intangible asset valuations, deferred income tax asset valuation allowances, uncertain tax positions, litigation, other loss contingencies, and impairment of long lived assets.

Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Due to the uncertainty regarding the success of future operations, management has valued the deferred tax asset allowance at 100% Because the Company operates in the State-licensed cannabis industry through the Nevada Subsidiaries, it is subject to the limitations of Internal Revenue Code Section 280E “280E” 280E, no may not 280E.
