1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
\u00a0
BUSINESS:
\u00a0
Aehr Test Systems (the \u201cCompany\u201d) was incorporated in California in May 1977 and primarily designs, engineers and manufactures test and burn-in equipment used in the semiconductor industry. The Company\u2019s principal products are the FOX-XP, FOX-NP, and FOX-CP wafer contact parallel test and burn-in systems, the WaferPak full wafer contactor, the DiePak carrier, the WaferPak aligner, the DiePak autoloader, and test fixtures.
\u00a0
CONSOLIDATION:
\u00a0
The consolidated financial statements include the accounts of the Company and both its wholly-owned and majority-owned foreign subsidiaries. Intercompany accounts and transactions have been eliminated.
\u00a0
FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS:
\u00a0
Assets and liabilities of the Company\u2019s foreign subsidiaries and a branch office are translated into U.S. Dollars from their functional currencies of Euros, Philippines Peso and New Taiwan Dollars using the exchange rate in effect at the balance sheet date. Additionally, their net sales and expenses are translated using exchange rates approximating average rates prevailing during the fiscal year. Translation adjustments that arise from translating their financial statements from their local currencies to U.S. Dollars are accumulated and reflected as a separate component of shareholders\u2019 equity.
\u00a0
Transaction gains and losses that arise from exchange rate changes denominated in currencies other than the local currency are included in the Consolidated Statements of Operations as incurred. See Note 15, \u201cOther (Expense) Income, Net\u201d for the detail of foreign exchange transaction gains and losses for all periods presented.
\u00a0
USE OF ESTIMATES:
\u00a0
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (\u201cGAAP\u201d) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates in the Company\u2019s consolidated financial statements include allowance for doubtful accounts, valuation of inventory at the lower of cost or net realizable value, and warranty reserves.
\u00a0
RECLASSIFICATIONS:
\u00a0
Certain reclassifications have been made to the previous year consolidated financial statements to conform to the current period presentation. The reclassifications had no impact on net income (loss), total assets, total liabilities, or shareholders\u2019 equity.
\u00a0
CASH EQUIVALENTS:
\u00a0
Cash equivalents consist of money market instruments purchased with an original maturity of three months or less. These investments are reported at fair value.
\u00a0
ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS:
\u00a0
Accounts receivable are derived from the sale of products throughout the world to semiconductor manufacturers, semiconductor contract assemblers, electronics manufacturers and burn-in and test service companies. Accounts receivable are recorded at the invoiced amount and are not interest bearing. The Company maintains an allowance for doubtful accounts to reserve for potentially uncollectible trade receivables. The Company also reviews its trade receivables by aging category to identify specific customers with known disputes or collection issues. The Company exercises judgment when determining the adequacy of these reserves as the Company evaluates historical bad debt trends, general economic conditions in the United States and internationally, and changes in customer financial conditions. Uncollectible receivables are recorded as bad debt expense when all efforts to collect have been exhausted and recoveries are recognized when they are received. During the fiscal year ended May 31, 2023, the Company recorded bad debt expense of $24,000. No significant adjustments to the allowance for doubtful accounts were recorded during the fiscal years ended May 31, 2022 or 2021.
\u00a0
CONCENTRATION OF CREDIT RISK:
\u00a0
The Company sells its products primarily to semiconductor manufacturers in North America, Asia, and Europe. As of May 31, 2023, approximately 17% and 83% of gross accounts receivable were from customers located in North America and Asia, respectively. As of May 31, 2022, approximately 20% and 80% of gross accounts receivable were from customers located in North America and Asia, respectively. Two customers accounted for 82% and 17% of gross accounts receivable as of May 31, 2023. Three customers accounted for 68%, 18% and 11% of gross accounts receivable as of May 31, 2022. Two customers accounted for 79% and 10% of net sales in fiscal 2023, respectively. One customer accounted for 82% of net sales in fiscal 2022. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company uses letter of credit terms for some of its international customers.
\u00a0
The Company\u2019s cash and cash equivalents are generally deposited with major financial institutions in the United States, Philippines, Germany and Taiwan. The Company invests its excess cash in money market funds and U.S. Treasury securities. The money market funds bear the risk associated with each fund. The money market funds have variable interest rates. The Company\u2019s cash and investment balances held at banks and brokerage firms may at time exceed federally insured levels. The Company has not experienced any material losses on its money market funds or short-term cash deposits.
\u00a0
CONCENTRATION OF SUPPLY RISK:
\u00a0
The Company relies on subcontractors to manufacture many of the components and subassemblies used in its products. Quality or performance failures of the Company\u2019s products or changes in its manufacturers\u2019 financial or business condition could disrupt the Company\u2019s ability to supply quality products to its customers and thereby have a material and adverse effect on its business and operating results. Some of the components and technologies used in the Company\u2019s products are purchased and licensed from a single source or a limited number of sources. The loss of any of these suppliers may cause the Company to incur additional transition costs, result in delays in the manufacturing and delivery of its products, or cause it to carry excess or obsolete inventory and could cause it to redesign its products.
\u00a0
INVENTORIES:
\u00a0
Inventories include material, labor and overhead, and are stated at the lower of cost (first-in, first-out method) or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less costs of completion, disposal and transportation. Provisions for excess, obsolete and unusable inventories are made after management\u2019s evaluation of future demand and market conditions. The Company adjusts inventory balances to approximate the lower of its manufacturing costs or net realizable value. If actual future demand or market conditions become less favorable than those projected by management, additional inventory write-downs may be required, and would be reflected in cost of sales in the period the revision is made. During fiscal 2023, 2022 and 2021 the Company recognized a provision for inventory reserves of $569,000, $1,031,000, and $176,000, respectively.
\u00a0
PROPERTY AND EQUIPMENT:
\u00a0
Property and equipment are stated at cost less accumulated depreciation and amortization. Major improvements are capitalized, while repairs and maintenance are expensed as incurred. Leasehold improvements are amortized over the lesser of their estimated useful lives or the term of the related lease. Furniture and fixtures, machinery and equipment, and test equipment are depreciated on a straight-line basis over their estimated useful lives. The ranges of estimated useful lives are generally as follows:
\u00a0
Furniture and fixtures\u00a0\u00a0\u00a0 | 2 to 6 years |
Machinery and equipment | 3 to 6 years |
Test equipment\u00a0\u00a0 | 4 to 6 years |
\u00a0\u00a0
REVENUE RECOGNITION:
\u00a0
The Company recognizes revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services by following a five-step process: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price, and (5) recognize revenue when or as the Company satisfies a performance obligation, as further described below.
\u00a0
Performance obligations include sales of systems, contactors, spare parts, and services, as well as installation and training services included in customer contracts.
\u00a0
A contract\u2019s transaction price is allocated to each distinct performance obligation. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. The Company generally does not grant return privileges, except for defective products during the warranty period.
\u00a0
For contracts that contain multiple performance obligations, the Company allocates the transaction price to the performance obligations on a relative standalone selling price basis. Standalone selling prices are based on multiple factors including, but not limited to, historical discounting trends for products and services and pricing practices in different geographies.
\u00a0
Revenue for systems and spares are recognized at a point in time, which is generally upon shipment or delivery. Revenue from services is recognized over time as services are completed or ratably over the contractual period of generally one year or less.
\u00a0
The Company has elected the practical expedient to not assess whether a contract has a significant financing component as the Company\u2019s standard payment terms are less than one year.
\u00a0
We sell our products primarily through a direct sales force. In certain international markets, we sell our products through independent distributors.
\u00a0
Transfer of control is evidenced upon passage of title and risk of loss to the customer unless we are required to provide additional services.
\u00a0
PRODUCT DEVELOPMENT COSTS AND CAPITALIZED SOFTWARE:
\u00a0
Costs incurred in the research and development of new products or systems are charged to operations as incurred. Costs incurred in the development of software programs for the Company\u2019s products are charged to operations as incurred until technological feasibility of the software has been established. Generally, technological feasibility is established when the software module performs its primary functions described in its original specifications, contains features required for it to be usable in a production environment, is completely documented and the related hardware portion of the product is complete. After technological feasibility is established, any additional costs are capitalized. Capitalization of software costs ceases when the software is substantially complete and is ready for its intended use. Capitalized costs are amortized over the estimated life of the related software product using the greater of the units of sales or straight-line methods over ten years. No system software development costs were capitalized or amortized in fiscal 2023, 2022 and 2021.
\u00a0
IMPAIRMENT OF LONG-LIVED ASSETS:
\u00a0
In the event that facts and circumstances indicate that the carrying value of assets may be impaired, an evaluation of recoverability would be performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset would be compared to the asset\u2019s carrying value to determine if a write-down is required.
\u00a0
ADVERTISING COSTS:
\u00a0
The Company expenses all advertising costs as incurred and the amounts were not material for all periods presented.
\u00a0
SHIPPING AND HANDLING OF PRODUCTS:
\u00a0
Amounts billed to customers for shipping and handling of products are included in net sales. Costs incurred related to shipping and handling of products are included in cost of sales.
\u00a0
INCOME TAXES:
\u00a0
Income taxes are accounted for under the asset-and-liability method as required by Financial Accounting Standards Board (\u201cFASB\u201d) Accounting Standards Codification (\u201cASC\u201d) Topic 740, Income Taxes (\u201cASC 740\u201d). Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period corresponding to the enactment date. Under ASC 740, a valuation allowance is required when it is more likely than not all or some portion of the deferred tax assets will not be realized through generating sufficient future taxable income.
\u00a0
As of May 31, 2023 the Company maintained a full valuation allowance against its deferred tax assets. We will continue to assess whether sufficient future taxable income will be generated to permit the use of deferred tax assets, and will reverse all or a portion of the allowance when there is sufficient evidence to support the reversal. Based upon our prior two fiscal years of profitability,\u00a0the outlook for\u00a0the next fiscal\u00a0year, and absent any additional objective negative evidence, the Company anticipates adjusting the current valuation allowance position in fiscal 2024.
\u00a0
FASB ASC Subtopic 740-10, Accounting for Uncertainty of Income Taxes, (\u201cASC 740-10\u201d) defines the criterion an individual tax position must meet for any part of the benefit of the tax position to be recognized in financial statements prepared in conformity with GAAP. The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not such tax position will be sustained on examination by the taxing authorities, based solely on the technical merits of the respective tax position. The tax benefits recognized in the financial statements from such a tax position should be measured based on the largest benefit having a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority. In accordance with the disclosure requirements of ASC 740-10, the Company\u2019s policy on income statement classification of interest and penalties related to income tax obligations is to include such items as part of income taxes.
\u00a0
COMPREHENSIVE INCOME (LOSS):
\u00a0
Comprehensive income (loss) generally represents all changes in shareholders\u2019 equity except those resulting from investments or contributions by shareholders. Unrealized gains and losses from available-for-sale securities and on foreign currency translation adjustments are included in the Company\u2019s components of comprehensive income (loss), which are excluded from net income (loss). In fiscal 2021, the Company recognized a gain of $2,401,000 related to the completed liquidation of ATS-Japan, a majority owned subsidiary, which is deducted from net income (loss) when calculating comprehensive income (loss). Refer to Note 18, \u201cDissolution of Aehr Test Systems Japan,\u201d for a further discussion of the transaction. Comprehensive income (loss) is included in the statements of comprehensive income (loss).
\u00a0
RECENT ACCOUNTING PRONOUNCEMENTS:
\u00a0
Accounting Standards Not Yet Adopted
\u00a0
In June 2016, the FASB issued Accounting Standard Update (\u201cASU\u201d) 2016-13, Financial Instruments \u2013 Credit Losses (Topic 326), that requires measurement and recognition of expected credit losses for financial assets held based on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Due to a subsequent ASU in November 2019, the accounting standard will be effective for the Company beginning in the first quarter of fiscal 2024 on a modified retrospective basis. The Company does not expect a material impact of this accounting standard on its consolidated financial statements.

The Company recognizes revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services by following a five-step process: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price, and (5) recognize revenue when or as the Company satisfies a performance obligation, as further described below.
\u00a0
Performance obligations include sales of systems, contactors, spare parts, and services, as well as installation and training services included in customer contracts.
\u00a0
A contract\u2019s transaction price is allocated to each distinct performance obligation. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. The Company generally does not grant return privileges, except for defective products during the warranty period.
\u00a0
For contracts that contain multiple performance obligations, the Company allocates the transaction price to the performance obligations on a relative standalone selling price basis. Standalone selling prices are based on multiple factors including, but not limited to, historical discounting trends for products and services and pricing practices in different geographies.
\u00a0
Revenue for systems and spares are recognized at a point in time, which is generally upon shipment or delivery. Revenue from services is recognized over time as services are completed or ratably over the contractual period of generally one year or less.
\u00a0
The Company has elected the practical expedient to not assess whether a contract has a significant financing component as the Company\u2019s standard payment terms are less than one year.
\u00a0
We sell our products primarily through a direct sales force. In certain international markets, we sell our products through independent distributors.
\u00a0
Transfer of control is evidenced upon passage of title and risk of loss to the customer unless we are required to provide additional services.

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period corresponding to the enactment date. Under ASC 740, a valuation allowance is required when it is more likely than not all or some portion of the deferred tax assets will not be realized through generating sufficient future taxable income.
\u00a0
As of May 31, 2023 the Company maintained a full valuation allowance against its deferred tax assets. We will continue to assess whether sufficient future taxable income will be generated to permit the use of deferred tax assets, and will reverse all or a portion of the allowance when there is sufficient evidence to support the reversal.

FASB ASC Subtopic 740-10, Accounting for Uncertainty of Income Taxes, (\u201cASC 740-10\u201d) defines the criterion an individual tax position must meet for any part of the benefit of the tax position to be recognized in financial statements prepared in conformity with GAAP. The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not such tax position will be sustained on examination by the taxing authorities, based solely on the technical merits of the respective tax position. The tax benefits recognized in the financial statements from such a tax position should be measured based on the largest benefit having a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority. In accordance with the disclosure requirements of ASC 740-10, the Company\u2019s policy on income statement classification of interest and penalties related to income tax obligations is to include such items as part of income taxes.

Contract balances\u00a0\u00a0\u00a0
\u00a0
A receivable is recognized in the period the Company delivers goods or provides services or when the Company\u2019s right to consideration is unconditional. The Company usually does not record contract assets because the Company has an unconditional right to payment upon satisfaction of the performance obligation, and therefore, a receivable is more commonly recorded than a contract asset.
\u00a0
Contract liabilities include payments received in advance of performance under a contract and are satisfied as the associated revenue is recognized. Contract liabilities are reported on the consolidated balance sheets at the end of each reporting period as a component of deferred revenue. Contract liabilities as of May 31, 2023 and 2022 were $2,853,000 and $2,484,000, respectively. \u00a0During the fiscal years ended May 31, 2023 and 2022, the Company recognized $2,179,000 and $189,000 of revenues that were included in contract liabilities as of May 31, 2022 and 2021, respectively.
\u00a0
Remaining performance obligations
\u00a0
On May 31, 2023, the Company had $163,000 of remaining performance obligations, exclusive of customer deposits, which were comprised of deferred service contracts and extended warranty contracts not yet delivered. The Company expects to recognize approximately 81% of its remaining performance obligations as revenue in fiscal 2024, and an additional 19% in fiscal 2025 and thereafter. The foregoing excludes the value of other remaining performance obligations as they have original durations of one year or less, and also excludes information about variable consideration allocated entirely to a wholly unsatisfied performance obligation.
\u00a0
Costs to obtain or fulfill a contract
\u00a0
The Company generally expenses sales commissions when incurred as a component of selling, general and administrative expense as the amortization period is typically less than one year. Additionally, the majority of the Company\u2019s cost of fulfillment as a manufacturer of products is classified as inventory and fixed assets, which are accounted for under the respective guidance for those asset types. Other costs of contract fulfillment are immaterial due to the nature of the Company\u2019s products and their respective manufacturing process.

3. EARNINGS PER SHARE (\u201cEPS\u201d):
\u00a0
Basic EPS is determined using the weighted average number of common shares outstanding during the period. Diluted EPS is determined using the weighted average number of common shares and potential common shares (representing the dilutive effect of stock options, restricted shares, restricted shares units, or RSUs, and ESPP shares) outstanding during the period using the treasury stock method.

For the purpose of computing diluted earnings per share, weighted average potential common shares do not include stock options with an exercise price greater than the average fair value of the Company\u2019s common stock for the period, as the effect would be anti-dilutive. Stock options to purchase 5,000 and 64,000 shares of common stock were outstanding as of May 31, 2023 and 2022, respectively, but were not included in the computation of diluted earnings per share, because the inclusion of such shares would be anti-dilutive. Stock options to purchase 2,766,000 shares of common stock were outstanding on May 31, 2021 but were not included in the computation of diluted net loss per share, because the inclusion of such shares would be anti-dilutive.\u00a0 ESPP rights to purchase 239,000 ESPP shares and RSUs for 132,000 shares were outstanding on May 31, 2021 but were not included in the computation of diluted net loss per share, because the inclusion of such shares would be anti-dilutive.

5. FAIR VALUE OF FINANCIAL INSTRUMENTS:
\u00a0
The Company\u2019s financial instruments are measured at fair value consistent with authoritative guidance. This authoritative guidance defines fair value, establishes a framework for using fair value to measure assets and liabilities, and disclosures required related to fair value measurements.
\u00a0
The guidance establishes a fair value hierarchy based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity\u2019s pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels:
\u00a0
Level 1 - instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets.
\u00a0
Level 2 - instrument valuations are obtained from readily-available pricing sources for comparable instruments.
\u00a0
Level 3 - instrument valuations are obtained without observable market values and require a high level of judgment to determine the fair value.
\u00a0
The following table summarizes the Company\u2019s financial assets measured at fair value on a recurring basis as of May 31, 2023 (in thousands):

The valuation allowance decreased by $1,121,000 during fiscal 2023, decreased by $278,000 during fiscal 2022, and increased by $2,438,000 during fiscal 2021. As of May 31, 2023 and 2022, the Company provided a full valuation allowance against the deferred tax assets as it\u00a0did not have enough objective evidence as required by GAAP to reverse its full valuation allowance. The Company will continue to evaluate the need for a valuation allowance against its deferred tax assets on a quarterly basis.
\u00a0
At May 31, 2023 and 2022, the Company has federal net operating loss carryforwards of approximately $46,967,000 and $61,068,000 respectively, to reduce future taxable income. A portion of the federal net operating losses will begin to expire in 2024. Federal net operating losses of $14,425,000 will carryforward indefinitely and would be subject to an 80% taxable income limitation in the year utilized. At May 31, 2023 and 2022, the Company has state net operating loss carryforwards of $30,203,000 and $30,043,000, respectively, to reduce future taxable income. The state net operating loss carryforwards will begin to expire in 2028.
\u00a0
At May 31, 2023 and 2022, the Company has federal research and development credit carryforwards of approximately $2,923,000 and $2,362,000, respectively, to offset future tax liability. The federal credit carryforwards began to expire in 2022. At May 31, 2023 and 2022, the Company has state research and development credit carryforwards of approximately $6,623,000 and $6,152,000 respectively, to offset future tax liability. The state credit carryforwards are not subject to expiration. The Company also has alternative minimum tax credit carryforwards of $34,000 for state purposes. The credits may be used to offset regular tax and do not expire.
\u00a0
Internal Revenue Code of 1986, as amended (\u201cIRC\u201d) Section 382 (\u201c\u00a7382\u201d) limits the use of NOL and tax credit carryforwards in certain situations where changes occur in the stock ownership of a company. In general, if we experience a greater than 50% aggregate change in ownership over a three-year period, we are subject to an annual limitation under IRC \u00a7382 on the utilization of the Company\u2019s pre-change NOL carryforwards. California and other states have similar laws. The annual limitation generally is determined by multiplying the value of the Company\u2019s stock at the time of such ownership change (subject to certain adjustments) by the applicable long-term exempt rate. Such limitations may result in expiration of a portion of the NOL carryforwards before utilization.
\u00a0
The Company has made no provision for U.S. income taxes on undistributed earnings of certain foreign subsidiaries because it is the Company\u2019s intention to permanently reinvest such earnings in its foreign subsidiaries. If such earnings were distributed, the Company would be subject to additional U.S. income tax expense.

The Company maintains liabilities for uncertain tax positions. These liabilities involve considerable judgment and estimation and are continuously monitored by management based on the best information available.

As of May 31, 2023 and 2022, the Company has not recorded interest and penalties associated with its unrecognized tax benefits. The Company\u2019s unrecognized gross tax benefits would not reduce the annual effective tax rate if recognized because it has recorded a full valuation allowance on its deferred tax assets. The Company does not foresee any material changes to the gross unrecognized tax benefit within the next twelve months. The Company\u2019s policy is to recognize interest and penalties in income tax expense.
\u00a0
The Company\u2019s federal and state income tax returns are subject to possible examination by the taxing authorities until the expiration of the related statutes of limitations on those tax returns. In general, the federal income tax returns have a three-year statute of limitations, and the state income tax returns have a four-year statute of limitations. The Company\u2019s foreign income tax returns are also subject to examination by the foreign tax authorities with the longest statute of limitations period of four-year.

10. LEASES
\u00a0
The Company leases its manufacturing and office space under operating leases. The principal administrative and production facility is located in Fremont, California, in a 51,289 square foot building. The Company entered into a non-cancelable operating lease agreement for its United States manufacturing and office facility, which was renewed in December 2022 and expires in September 2030. The Company leases a 492 square foot sales and support office in Utting, Germany. The lease, which began on February 1, 1992 and expires on January 31, 2025, contains an automatic twelve months renewal, at rates to be determined, if no notice is given prior to six months from expiration. The Company leases a facility in the Philippines located in a 2,713 square foot building in Clark Freeport Zone, Pampanga. The lease, which began on January 1, 2021 and expires on December 31, 2025, contains an option to renew for another three years at rates stipulated in the contract, notice for renewal is given six months from expiration. Under the lease agreements, the Company is responsible for payments of utilities, taxes and insurance.
\u00a0
The Company has only operating leases for real estate including corporate offices, warehouse space and certain equipment. A lease with an initial term of 12 months or less is generally not recorded on the consolidated balance sheets, unless the arrangement includes an option to purchase the underlying asset, or renew the arrangement that the Company is reasonably certain to exercise (short-term leases). The Company recognizes lease expense on a straight-line basis over the lease term for short-term leases that the Company does not record on its balance sheets. The Company\u2019s operating leases have remaining lease terms of one year to seven years.
\u00a0
The Company determines whether an arrangement is or contains a lease based on the unique facts and circumstances present at the inception of the arrangement. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company utilizes the appropriate incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term at an amount equal to the lease payments in a similar economic environment. Certain adjustments to the right-of-use asset may be required for items such as initial direct costs paid or incentives received.
\u00a0
In December 2022, the Company amended its lease agreement to extend the lease term of an existing office facility located in the United States, which is considered a lease modification not accounted for as a separate contract. The total commitments, net of tenant incentives expected to be received, under the modified lease are $8.6 million. The modified lease expires in fiscal 2031 and contains an option to further extend the lease. The lease modification resulted in an increase in the Company\u2019s operating lease right-of-use assets and operating lease liabilities of $5.9 million each.
\u00a0

11. BORROWING AND FINANCING ARRANGEMENTS:
\u00a0
On January 16, 2020, the Company entered into a Loan and Security Agreement (the \u201cLoan Agreement\u201d) with Silicon Valley Bank (\u201cSVB\u201d). Pursuant to the Loan Agreement, the Company may borrow up to (a) the lesser of (i) the revolving line of $4.0 million or (ii) the amount available under the borrowing base under a revolving line of credit which is collateralized by all the Company\u2019s assets except intellectual property. The borrowing base is 80% of eligible accounts, as determined by SVB from the Company\u2019s most recent borrowing base statement; provided, however, SVB has the right to decrease the foregoing percentage in its good faith business judgment to mitigate the impact of certain events or conditions, which may adversely affect the collateral or its value. Subject to an event of default, the principal amount outstanding under the revolving line of credit will accrue interest at a floating per annum rate equal to the greater of (a) the prime rate plus an additional percentage of up to 1%, which additional percentage depends on the Company\u2019s adjusted quick ratio, and (b) 4.75%. Interest is payable monthly on the last calendar day of each month and the outstanding principal amount, the unpaid interest and all other obligations are due on the maturity date, which is 364 days from the effective date of January 13, 2020.
\u00a0
On January 14, 2021, the Company entered into the First Amendment to Loan and Security Agreement (the \u201cAmendment\u201d) with SVB. The Amendment, among other things, extended the Revolving Line Maturity Date to July 14, 2021; provided, however, that if the Company achieved specified operating metrics on a consolidated basis on or prior to May 31, 2021 the Amended Revolving Line Maturity Date would be extended to January 13, 2022.
\u00a0
On January 11, 2022, the Company entered into the Second Amendment to the Loan and Security Agreement (the \u201cSecond Amendment\u201d) with SVB. The Second Amendment, among other things, (A) increased the available amount of the line up to the lesser of (i) $10 million or (ii) the available amount under the borrowing base, under a revolving line of credit, (B) allowed for borrowing up to $3 million of the available balance based upon eligible customer purchase orders, (C) reduced the interest rate for account advances under the line to the greater of (a) prime rate plus an additional percentage up to 1.0%, which additional percentage depends on the Company\u2019s adjusted quick ratio, and (b) 3.25%, reduces the interest rate for purchase order advances under the line to the greater of (a) prime rate plus an additional percentage up to 1.5%, which additional percentage depends on the Company\u2019s adjusted quick ratio, and (b) 3.75%, and (D) extended the maturity date to January 13, 2023.
\u00a0
On January 10, 2023, the Company entered into the Third Amendment to the Loan and Security Agreement (the \u201cThird Amendment\u201d) with SVB. The Third Amendment, among other things, extends the Revolving Line Maturity Date to January 13, 2024, provided, however, that (i) if the Company submits a fiscal year 2024 plan of record that is generally acceptable to SVB, and (ii) the minimum net liquidity at the end of November 30, 2023 is at least $20.0 million, the Amended Revolving Line Maturity Date would be extended to January 13, 2025.
\u00a0
As of May 31, 2023 the Company had not drawn against the credit facility and was in compliance with all covenants related to obligations to meet reporting requirements. The balance available to borrow under the line as of May 31, 2023 was $8,004,000. There are no financial covenants in the agreement.

STOCK-BASED COMPENSATION:
\u00a0
Stock-based compensation expense consists of expenses for stock options, restricted stock units (\u201cRSUs\u201d), performance RSUs, or PRSUs, restricted shares, performance restricted shares and employee stock purchase plan, or ESPP, purchase rights. Stock-based compensation expense for stock options and ESPP purchase rights is measured at each grant date, based on the fair value of the award using the Black-Scholes option valuation model, and is recognized as expense over the employee\u2019s requisite service period. This model was developed for use in estimating the value of publicly traded options that have no vesting restrictions and are fully transferable. The Company\u2019s employee stock options have characteristics significantly different from those of publicly traded options. For RSUs, PRSUs, restricted shares and performance restricted shares, stock-based compensation expense is based on the fair value of the Company\u2019s common stock at the grant date, and is recognized as expense over the employee\u2019s requisite service period. All of the Company\u2019s stock-based compensation is accounted for as equity instruments.

As of the years ended May 31, 2023, 2022 and 2021, stock-based compensation totaling $120,000, $83,000 and $0, respectively, was capitalized as part of inventory.
\u00a0
During fiscal 2023, 2022 and 2021, the Company recorded stock-based compensation related to stock options, RSUs, PRSUs, performance restricted shares and restricted shares of $1,988,000, $2,071,000 and $993,000, respectively. For PRSUs and performance restricted shares, the Company evaluates compensation expense quarterly and recognizes expense for performance-based awards only if it determines it is probable that performance criteria for the awards will be met.
\u00a0
As of May 31, 2023, the total compensation expense related to unvested stock-based awards under the Company\u2019s 2016 Equity Incentive Plan, but not yet recognized, was $3,102,000 which is net of estimated forfeitures of $8,000. This expense will be amortized on a straight-line basis over a weighted average period of approximately 2.3 years.
\u00a0
During fiscal 2023, 2022 and 2021, the Company recorded stock-based compensation related to its ESPP of $760,000, $935,000 and $108,000, respectively.
\u00a0
As of May 31, 2023, the total compensation expense related to purchase rights under the ESPP but not yet recognized was $715,000. This expense will be amortized on a straight-line basis over a weighted average period of approximately 1.1 years.
\u00a0
Valuation Assumptions
\u00a0
Valuation and Amortization Method. The Company estimates the fair value of stock options granted using the Black-Scholes option valuation method and a single option award approach. The fair value under the single option approach is amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period.
\u00a0
Expected Term. The Company\u2019s expected term represents the period that the Company\u2019s stock-based awards are expected to be outstanding and was determined based on historical experience, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior as evidenced by changes to the terms of its stock-based awards.
\u00a0
Volatility. Volatility is a measure of the amounts by which a financial variable such as stock price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. The Company uses the historical volatility for the past five to six years, based on weighted average of the expected term of option grants, to estimate expected volatility. Volatility for each of the ESPP\u2019s four time periods of six months, twelve months, eighteen months, and twenty-four months is calculated separately and included in the overall stock-based compensation expense recorded.
\u00a0
Risk-Free Interest Rate. The Company bases the risk-free interest rate used in the Black-Scholes option valuation method on the implied yield in effect at the time of option grant on U.S. Treasury zero-coupon issues with a remaining term equivalent to the expected term of the stock awards including the ESPP.
\u00a0\u00a0
Fair Value. The fair values of the Company\u2019s stock options granted to employees in fiscal 2023, 2022 and 2021 were estimated using the following weighted average assumptions in the Black-Scholes option valuation method:

EQUITY INCENTIVE PLAN:
\u00a0
In October 2006, the Company\u2019s 2006 Equity Incentive Plan was approved by the shareholders, which provides for granting of incentive stock options, non-statutory stock options, restricted shares, RSUs, stock appreciation rights, PRSUs, performance restricted shares and other stock or cash awards as the Company\u2019s Board of Directors may determine.
\u00a0
In October 2016, the Company\u2019s 2016 Equity Incentive Plan was approved by the Company\u2019s shareholders. The 2016 Equity Incentive Plan replaced our 2006 Equity Incentive Plan, which was scheduled to expire in October 2016, and will continue in effect until 2026. The exercise price of each stock option equals the market value of the Company's common stock on the date of grant. Options typically vest over four years, subject to the grantee\u2019s continued service with the Company through the scheduled vesting date, and expire in seven years from the grant date. A total of 4,848,000 shares of common stock have been reserved for issuance under the Company\u2019s 2016 Equity Incentive Plan, which includes 2,248,000 shares that remained available for issuance under the 2006 Equity Incentive Plan. Full value awards, which are equity awards other than options, stock appreciation rights or other awards that are based solely on an increase in value of the shares following the grant date, when granted or forfeited will be counted as two times the number of shares added or deducted to the remaining available shares for issuance under 2016 Equity Incentive Plan. See the Company\u2019s Registration Statement on Form S-8 filed with the Securities and Exchange Commission on November 16, 2021 for further information regarding the 2016 Equity Incentive Plan.

In October 2006, the Company\u2019s shareholders approved the 2006 Employee Stock Purchase Plan. In October 2016, the Company\u2019s shareholders approved the Company\u2019s Amended and Restated 2006 Employee Stock Purchase Plan (the \u201cPurchase Plan\u201d), which amended and restated the 2006 Employee Stock Purchase Plan. The Purchase Plan extended the term of the 2006 Employee Stock Purchase Plan indefinitely. See the Company\u2019s Registration Statements on Form S-8 filed with the Securities and Exchange Commission on November 18, 2020 and November 16, 2022 for further information regarding the Purchase Plan. The Purchase Plan has consecutive, overlapping, twenty-four month offering periods. Each twenty-four-month offering period includes four six-month purchase periods. The offering periods generally begin on the first trading day on or after April 1 and October 1 each year. All employees who work a minimum of 20 hours per week and are customarily employed by the Company (or an affiliate thereof) for at least five months per calendar year are eligible to participate. Under the Purchase Plan, shares are purchased through employee payroll deductions at exercise prices equal to 85% of the lesser of the fair market value of the Company\u2019s common stock at either the first day of an offering period or the last day of the purchase period. If a participant\u2019s rights to purchase stock under all employee stock purchase plans of the Company accrue at a rate which exceeds $25,000 worth of stock for a calendar year, such participant may not be granted an option to purchase stock under the Purchase Plan. The maximum number of shares a participant may purchase during a single purchase period is 3,000 shares. In October 2022, the Company\u2019s shareholders approved an amendment to the Purchase Plan to increase the number of shares authorized for issuance thereunder by an additional 350,000 shares of the Company\u2019s common stock. After such amendment, a total of 2,550,000 shares of the Company\u2019s common stock have been authorized for issuance under the Purchase Plan. During the fiscal years ended May 31, 2023, 2022 and 2021, ESPP purchase rights of 77,000, 101,000, and 279,000 shares, respectively, were granted. For the fiscal years ended May 31, 2023, 2022 and 2021, approximately 211,000, 178,000 and 147,000 shares of common stock, respectively, were issued under the Purchase Plan. As of May 31, 2023, a total of 2,152,000 shares have been issued under the Purchase Plan, and 398,000 ESPP shares remain available for issuance.

14. EMPLOYEE BENEFIT PLANS:
\u00a0
EMPLOYEE STOCK OWNERSHIP PLAN:
\u00a0
The Company has a non-contributory, trusteed employee stock ownership plan for full-time employees who have completed three consecutive months of service and for part-time employees who have completed one year of service and have attained an age of 21. The Company can contribute either shares of the Company\u2019s stock or cash to the plan. The contribution is determined annually by the Company and cannot exceed 15% of the annual aggregate salaries of those employees eligible for participation in the plan. On May 31, 2007, the Company converted the Aehr Test Systems Employee Stock Bonus Plan into the Aehr Test Systems Employee Stock Ownership Plan (the \u201cPlan\u201d). The stock bonus plan was converted to an employee stock ownership plan (\u201cESOP\u201d) to enable the Plan to better comply with changes in the law regarding Company stock. Individuals\u2019 account balances vest at a rate of 20% per year commencing upon completion of two years of service. Non-vested balances, which are forfeited following termination of employment, are allocated to the remaining employees in the Plan. Under the Plan provisions, each employee who reaches age fifty-five (55) and has been a participant in the Plan for ten years will be offered an election each year to direct the transfer of up to 25% of his/her ESOP account to the employee self-directed account in the Savings and Retirement Plan. For anyone who met the above prerequisites, the first election to diversify holdings was offered after May 31, 2008. In the sixth year, employees will be able to diversify up to 50% of their ESOP accounts. Contributions of $300,000 were authorized for the plan during fiscal 2023, $250,000 for 2022 and $60,000 for 2021. The contribution amounts are recorded as compensation expense in the period authorized and included in accrued expenses in the period authorized. Contributions of 29,832 shares were made to the ESOP during fiscal 2023 for fiscal 2022. Contributions of 26,666 shares were made to the ESOP during fiscal 2022 for fiscal 2021. Contributions of 36,000 shares were made to the ESOP during fiscal 2021 for fiscal 2020. The contribution for fiscal 2023 will be made in fiscal 2024. Shares held in the ESOP are included in the EPS calculation.
\u00a0
401(K) PLAN:
\u00a0
The Company maintains a defined contribution savings plan (the \u201c401(k) Plan\u201d) to provide retirement income to all qualified employees of the Company. The 401(k) Plan is intended to be qualified under Section 401(k) of the Internal Revenue Code of 1986, as amended. The 401(k) Plan is funded by voluntary pre-tax contributions from employees. Contributions are invested, as directed by the participant, in investment funds available under the 401(k) Plan. The Company is not required to make, and did not make, any contributions to the 401(k) Plan during fiscal 2023, 2022 and 2021.

16. PRODUCT WARRANTIES:
\u00a0
The Company provides for the estimated cost of product warranties at the time revenues are recognized on the products shipped. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its component suppliers, the Company\u2019s warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. Should actual product failure rates, material usage or service delivery costs differ from the Company\u2019s estimates, revisions to the estimated warranty liability would be required.
\u00a0
The standard warranty period is one year for systems and ninety days for parts and service.

COMMITMENTS
\u00a0
As of May 31, 2023 and 2022, the Company had restricted money market funds of $150,000 and $80,000, respectively, held by a financial institution, representing a security deposit for its United States manufacturing and office space lease. This amount is included in other assets on the consolidated balance sheets.
\u00a0
PURCHASE OBLIGATIONS
\u00a0
The Company has purchase obligations to certain suppliers. In some cases, the products the Company purchases are unique and have provisions against cancellation of the order. At May 31, 2023, the Company had $26,318,000 of purchase obligations which are due within the following 12 months. This amount does not include contractual obligations recorded on the consolidated balance sheets as liabilities.
\u00a0
CONTINGENCIES
\u00a0
The Company may, from time to time, be involved in legal proceedings arising in the ordinary course of business. While there can be no assurances as to the ultimate outcome of any litigation involving the Company, management does not believe any pending legal proceedings will result in judgment or settlement that will have a material adverse effect on the Company\u2019s consolidated financial position, results of operations or cash flows.
\u00a0
In the normal course of business to facilitate sales of its products, the Company indemnifies other parties, including customers, with respect to certain matters, for example, including against losses arising from a breach of representations or covenants, or from intellectual property infringement or other claims. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. In addition, the Company has entered into indemnification agreements with its officers and directors, and the Company\u2019s bylaws contain similar indemnification obligations to the Company\u2019s agents.
\u00a0
It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. To date, payments made by the Company under these agreements have not had a material impact on the Company\u2019s operating results, financial position or cash flow.
