Leases | NOTE 6 —Leases The Company adopted ASU 2016-02 on January 1, 2022. The Company elected to use “the effective date” method where the comparative reporting periods is unchanged from legacy US GAAP. The Company elected the package of practical expedients to not reassess the classifications of existing leases and to not reassess if initial direct costs qualify for capitalization. The Company identified and continued to classify six leases as operating leases at January 1, 2022. All of the Company’s leases are for office space. The Company has elected the practical expedient to not separate lease components from non-lease components for all leases. At adoption of ASC 842, the Company determined the fair value of the lease liability for each of the four operating leases (excluding the short-term leases) as the net present value of future lease payments using the Company’s incremental borrowing rate of 8.5%. The incremental borrowing rate was determined by management as the interest rate that the Company would pay for a loan with a repayment stream that is the same as the lease payment stream and for a loan that is secured by the underlying lease assets. The Company determined that the incremental rate was 8.5% for all four leases at January 1, 2022. An ROU asset that represents the Company’s right to use the leased asset, was established at adoption for the same amount as the lease liability. Per ASC 842, ROU assets were reduced by $142 with the derecognition of deferred lease liabilities from December 31, 2021. One of the Company’s ROU assets is part of an asset group that had indicators of impairment (sublease income that is significantly less than the head lease obligation) as of December 31, 2021 and accordingly subject to an impairment analysis under ASC 360 at that time. At December 31, 2021 the amount of leasehold improvements and other recorded assets related to the asset group were not significant and as a result no impairment was required prior to adoption of ASC 842; however, had the recorded assets of the group at December 31, 2021 been significant an impairment charge would have been required. Upon adoption of ASC 842 and the recording of the ROU asset within this asset group, the Company reassessed impairment under ASC 360. As a result of this assessment, it was determined that as of the adoption date the fair value of the asset group was less than the recorded carrying value upon adoption and an impairment related to the ROU asset of $978 was required. Since all impairment conditions and events were present at December 31, 2021 as well as the adoption date, the Company recognized the impairment of $978 as an adjustment to beginning of the year retained earnings upon the adoption date. The Company entered into a sublease for the above property in September 2021 that had sublease income that was significantly less than the head lease payments. This sublease is for 13 months which, at the option of the subtenant, can be extended for 12 additional months. In determining the fair value of the ROU asset, the Company assumed that the subtenant will extend the lease because the sublease payments are less than market value. The Company determined that the fair value of the ROU asset as the sum of the sublease payments for the 25 months of the sublease. The Company is amortizing this ROU asset as sublease payments are received. On August 31, 2022, the Company entered into an agreement with the landlord to cancel the head lease for $260 in consideration paid by the Company to the landlord. On August 31, 2022 the Company derecognized the remaining lease liability and ROU asset. This resulted in a $730 gain on the termination of the lease. The sublease was terminated when the head lease was terminated. The Company elected the practical expedient for short-term leases for two leases that had terms of one year or less. ROU assets and lease liabilities were not established for these two short-term leases and rent payments are recorded as rent expense. On January 1, 2022 the Company began recording all lease payments as the payment of lease interest expense and a reduction of the lease liability for the four leases that are not short-term. ROU assets are amortized over the life of the Company’s lease. The following table shows the activity of the ROU assets and lease liability for the year ended on December 31, 2022: Summary of Activity of ROU Assets and Lease Liability

In connection with leases, for the year ended December 31, 2022, the Company recognized $398 for the amortization of ROU assets, $97 for interest expense on lease liabilities, and no rent expense that was included in Cost of Revenues. Variable lease payments, including reimbursements to the landlord for property taxes and operating expenses, of approximately $143 and short-term rent payments of $11 were included in rent expense for the year ended December 31, 2022, and were offset by $80 in sublease income. The Company does not have any lease extension or termination options on any lease. There are no residual value guarantees in any lease. The weighted average remaining lease term of the operating leases is approximately 0.2 years. The weighted average of the discount rate for both the discount rate used to calculate the lease liabilities and the remaining balance of the lease payments for each lease as of December 31, 2022 is 8.5%.
