SELECT BALANCE SHEET DETAILS Inventory Inventories of $24,000 as of March 31, 2022 were comprised of work in process of $7,000, representing direct labor costs on in-process projects and finished goods of $17,000 net of reserves for obsolete and slow-moving items of $3,000.

Appropriate consideration is given to obsolescence, excessive levels, deterioration and other factors in evaluating net realizable value and required reserve levels. Goodwill The Company annually, or more frequently if events or circumstances indicate a need, tests the carrying amount of goodwill for impairment. The Company performs its annual impairment test in the fourth quarter of each year. In December 2018, the Company adopted the provisions of ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The provisions of ASU 2017-04 eliminate the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit's carrying amount over its fair value. Entities that have reporting units with zero or negative carrying amounts will no longer be required to perform a qualitative assessment assuming they pass the simplified impairment test. The Company continues to have only one reporting unit, Identity Management, which, at March 31, 2022, had a negative carrying amount of approximately $18,961,000. Based on the results of the Company's impairment testing, the Company determined that its goodwill was not impaired as of March 31, 2022 and December 31, 2021 as the fair value of our Identity Management reporting unit exceeded that reporting unit’s carrying value. However, the Company has experienced decreases in its market capitalization and if our market capitalization continues to decrease, future impairment of goodwill may result. Other Assets In conjunction with the LPC Purchase Agreement, the Company issued to Lincoln Park, in May 2021, 1,000,000 shares of Common Stock as consideration for entering into the LPC Purchase Agreement. Pursuant to this issuance, the Company recorded $70,000 as a deferred stock issuance cost. Such deferred stock issuance costs will be recognized as a charge against paid-in capital in proportion to securities sold under the LPC Purchase Agreement. At March 31, 2022, the Company had approximately $70,000 in deferred stock issuance costs included in the caption “Other assets” in its condensed consolidated balance sheets.
