The preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. The Company evaluates on an ongoing basis its assumptions, including those related to contingencies, Fair values of financial instruments, inventory write-offs, as well as in estimates used in applying the revenue recognition policy. The Company's management believes that the estimates, judgments, and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the unaudited condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Treasury shares represents ordinary shares repurchased by the Company that are no longer outstanding and are held by the Company. Treasury shares is accounted for under the cost method. Under this method, repurchase of ordinary shares was recorded as treasury shares at historical purchase price. At retirement, the ordinary shares account is charged only for the aggregate par value of the shares. The treasury shares have no rights.

The Company’s lease accounting policy until December 31, 2021, prior to the adoption of the new lease standard - ASC-842

The Company leases real estate and cars for use in its operations, which are classified as operating leases. Rental expense for the three and six months ended June 30, 2021 were $106 and $204, respectively.

The lease expenses are recognized on a straight-line basis over the expected lease term and is included in the operating expenses in the Company’s condensed consolidated statements of operations.

The Company’s lease accounting policy from January 1, 2022, following the adoption of the new lease standard

The Company adopted the new lease standard and all the related amendments on a prospective basis as of January 1, 2022 and used the effective date as the Company’s date of initial application. Consequently, historical financial information was not updated, and the disclosures required under the new standard are not provided for dates and periods before January 1, 2022.

Rental expense for the three and six months ended June 30, 2022 were $158 and $262, respectively.

The new lease standard provides a number of optional practical expedients in transition. The Company elected the ‘package of practical expedients,’ which permits the Company not to reassess its prior conclusions regarding lease identification, lease classification and initial direct costs under the new standard. The Company has also elected the practical expedient pertaining to the use of hindsight.

Operating lease ROU assets represent the right to use the leased asset for the lease term and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most leases do not provide an implicit rate, the Company use an incremental borrowing rate based on the information available at the adoption date in determining the present value of future payments.

The new lease standard also provides practical expedients for an entity’s ongoing accounting. The Company elected the short-term lease recognition exemption for all leases with a term shorter than 12 months. This means, for those leases, The Company does not recognize ROU assets or lease liabilities, including not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition The Company also elected to apply the practical expedient to not separate lease and non-lease components for its real-estate leases.

Regarding leases denominated in a foreign currency, the related ROU assets are remeasured using the exchange rate in effect at the date of initial recognition; the related lease liabilities are remeasured using the exchange rate in effect at the end of the reporting period.

Certain of the Company’s lease agreements include rental payments based on changes in the CPI. Lease liabilities are not remeasured as a result of changes in the CPI; instead, changes in the CPI are treated as variable lease payments and recognized in the period in which the related obligation was incurred. The Company includes these variable payments in the initial measurement of the lease right-of-use asset and lease liability. On the effective date, the Company included, in the initial measurement of the ROU asset and lease liability, the lease payments based on the then-current CPI.

In lease agreements that include extension options, the lease term includes the options to extend the lease, only to the extent it is reasonably certain that the Company will exercise such extension options.

The application of ASC 842 has resulted in the recognition of approximately $1,046 ROU assets and lease liabilities on the Company’s balance sheet as of the effective date, and in the requirement to provide significant new disclosures regarding the Company’s leasing activities and to enable users of financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. However, the adoption of this standard does not have a significant impact on the Company’s consolidated statements of comprehensive loss and consolidated statements of cash flows. See note 7 for further discussion.

Sublease

In October 2021, the Company entered a sublease agreement for its offices in the USA. The Company applies the guidelines in ASC-842 regarding subleases, which states that the classification should be based on the underlying asset being subleased and concluded that the sublease is an operating lease where the Company is the Lessor.

The sublease income is recognized on a straight-line basis over the expected lease term and is included in the operating expenses in the Company’s condensed consolidated statements of operations.

Fair value measurements are classified and disclosed in one of the following three categories:

Level 1 – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2 – Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The following table represents the fair value hierarchy for the Company's financial assets and liabilities measured at fair value on a recurring basis as of:

As of June 30, 2022, and December 31, 2021, the fair values of the Company's cash, cash equivalents, short and long-term deposits, trade receivables, trade payables, long-term loan and restricted cash approximated the carrying values of these instruments presented in the Company's consolidated balance sheets because of their nature.

As an emerging growth company, the Jumpstart Our Business Startup Act (“JOBS Act”) allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. The Company has elected to use this extended transition period under the JOBS Act. The adoption dates discussed below reflect this election.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the existing incurred loss impairment model with an expected credit loss model and requires a

financial asset measured at amortized cost to be presented at the net amount expected to be collected. The guidance will be effective for the Company beginning January 1, 2023, and interim periods therein. Early adoption is permitted. The Company is currently evaluating the effect that ASU 2016-13 will have on its consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04 “Reference Rate Reform (Topic 848)—Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The guidance applies only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. This guidance is effective for all entities as of March 12, 2020, through December 31, 2022.

The Company's exposure to reference rate reform is due to royalties payments the Company is obligated to pay for research and development grants received from the Government of Israel (see note 8b). As of the date of these condensed consolidated financial statements, the Israeli Innovation Authority ("IIA") has not determined an alternative benchmark rate to the LIBOR. However, the Company will consider this guidance as future modifications are made.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (“Topic 740”): Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. ASU No. 2019-12 is effective for the Company for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The adoption of this guidance will not have a significant impact on the Company’s consolidated financial statements.

In November 2021, the FASB issued ASU 2021-10, “Government Assistance (Topic 832): Disclosures by Business Entities About Government Assistance.” ASU 2021-10 requires disclosures about transactions with a government that have been accounted for by a grant or contribution accounting model to increase transparency about the types of transactions, the accounting for the transactions, and the effect on the financial statements. The ASU is an annual disclosure effective for fiscal years beginning after December 15, 2021 and will be applied on a prospective basis. The Company is currently evaluating the impact this new standard will have on the consolidated financial statements and related disclosures but does not believe there will be a material impact.

In June 2020 the FASB issued Accounting Standards Update ("ASU") 2020-06, "Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity" ("ASU 2020-06"). ASU 2020-06 simplifies the accounting for certain convertible instruments, amends guidance on derivative scope exceptions for contracts in an entity's own equity and modifies the guidance on diluted earnings per share calculations as a result of these changes. ASU 2020-06 will be effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating the effect of this standard on its consolidated financial statements.
