Under U.S. GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are obtained from independent sources and can be validated by a third party, whereas unobservable inputs reflect assumptions regarding what a third party would use in pricing an asset or liability. The fair value hierarchy consists of three levels based on the reliability of inputs, as follows:

The Company evaluates assets and liabilities subject to fair value measurements on a recurring and non-recurring basis to determine the appropriate level to classify them for each reporting period. This determination requires significant judgments to be made by management of the Company. The financial instruments identified as subject to fair value measurements on a recurring basis are cash and cash equivalents, notes receivable, trade accounts receivable, and trade accounts payable. All financial instruments are reflected in the condensed consolidated balance sheets at carrying value, which approximates fair value due to the short-term nature of these financial instruments.

Assets that are measured at fair value on a non-recurring basis include property and equipment, leasehold improvements, and intangible assets comprising patents, license rights, and trademarks. These items are recognized at fair value when they are considered to be impaired. For the three and nine months ended March 31, 2022 and 2021, no impairment was recorded.

As of March 31, 2022, the Company’s management determined that its expectations of future taxable income in upcoming tax years, including estimated growth rates applied to future expected taxable income that includes significant management estimates and assumptions, would continue to be sufficient to result in full utilization of the Company’s remaining federal net operating loss carryforwards and certain of the deferred tax assets prior to any statutory expiration. As a result, the Company’s management determined that sufficient positive evidence existed as of March 31, 2022, to conclude that it is more likely than not deferred tax assets of approximately $5.87 million remain realizable. Conversely, the Company’s management further determined that sufficient negative evidence continued to exist to conclude it was uncertain that the Company would have sufficient future taxable income to utilize certain of its deferred tax assets. Therefore, the Company continued to maintain a valuation allowance against the deferred tax assets relating to certain state net operating loss carryforwards from the Company’s e-commerce subsidiary due to the timing uncertainty of when it will generate positive taxable income to utilize the associated deferred tax assets. In addition, a valuation allowance remains against certain deferred tax assets relating to operating loss carryforwards relating to the Company’s dormant subsidiary located in Hong Kong.

The Company’s total operating lease cost was approximately $193,000 and $192,000 for the three months ended March 31, 2022 and 2021, respectively. The Company’s total operating lease cost was approximately $596,000 and $473,000 for the nine months ended March 31, 2022 and 2021, respectively.
