AEHR TEST SYSTEMS
NOTESNOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)
 
1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCCOUNTING POLICIES
 
    The accompanying financial information has been prepared by Aehr Test Systems, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission or SEC.(the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (GAAP)(“GAAP”) have been condensed or omitted pursuant to such rules and regulations.
 
    In the opinion of management, the unaudited condensed consolidated financial statements for the interim periods presented have been prepared on a basis consistent with the May 31, 20172020 audited consolidated financial statements and reflect all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the condensed consolidated financial position and results of operations as of and for such periods indicated. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended May 31, 2017.2020. Results for the interim periods presented herein are not necessarily indicative of results which may be reported for any other interim period or for the entire fiscal year.
 
    PRINCIPLES OF CONSOLIDATION. The condensed consolidated financial statements include the accounts of Aehr Test Systems and its subsidiaries (collectively, the "Company"). All significant intercompany balances have been eliminated in consolidation. For the Company’sCompany's majority owned subsidiary, Aehr Test Systems Japan K.K., the noncontrolling interest of the portion the Company does not own was reflected on the Condensed Consolidated Balance Sheets in Shareholders’Sharholders' Equity and in the Condensed Consolidated Statements of Operations.
 
    ACCOUNTING ESTIMATES. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. Estimates are used to account for sales and revenue allowances, the allowance for doubtful accounts, inventory valuations, income taxes, stock-based compensation expenses, and product warranties, among others. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances. Actual results could differ materially from those estimates.
 
    REVENUE RECOGNITION. The Company recognizes revenue upon the shipment of products or the performance of services when: (1) persuasive evidence of the arrangement exists; (2) goods or services have been delivered; (3) the price is fixed or determinable; and (4) collectibility is reasonably assured. When a sales agreement involves multiple deliverables, such as extended support provisions, training to be supplied after delivery of the systems, and test programs specific to customers’ routine applications, the multiple deliverables are evaluated to determine the unit of accounting. Judgment is required to properly identify the accounting units of multiple element transactions and the manner in which revenue is allocated among the accounting units. Judgments made, or changes to judgments made, may significantly affect the timing or amount of revenue recognition.
    Revenue related to the multiple elements is allocated to each unit of accounting using the relative selling price hierarchy. Consistent with accounting guidance, the selling price is based upon vendor specific objective evidence (VSOE). If VSOE is not available, third party evidence (TPE) is used to establish the selling price. In the absence of VSOE or TPE, estimated selling price is used.

    During the first quarter of fiscal 2013, the Company entered into an agreement with a customer to develop a next generation system, and the Company shipped the first system in July 2016. The project identifies multiple milestones with values assigned to each. The consideration earned upon achieving the milestone is required to meet the following conditions prior to recognition: (i) the value is commensurate with the vendor’s performance to meet the milestone, (ii) it relates solely to past performance, (iii) and it is reasonable relative to all of the deliverables and payment terms within the arrangement. Revenue is recognized for the milestone upon acceptance by the customer.
    The Company recognizes revenue in certain circumstances before physical delivery has occurred. In these arrangements, among other things, risk of ownership has passed to the customer, the customer has made a written fixed commitment to purchase the products, the customer has requested the products be held for future delivery as scheduled and designated by them, and no additional performance obligations exist by the Company. For these transactions, the products are segregated from inventory and normal billing and credit terms granted.
    Sales tax collected from customers is not included in net sales but rather recorded as a liability due to the respective taxing authorities. Provisions for the estimated future cost of warranty and installation are recorded at the time the products are shipped.
    Royalty-based revenue related to licensing income from performance test boards and burn-in boards is recognized upon the earlier of the receipt by the Company of the licensee’s report related to its usage of the licensed intellectual property or upon payment by the licensee.
    The Company’s terms of sales with distributors are generally FOB shipping point with payment due within 60 days. All products go through in-house testing and verification of specifications before shipment. Apart from warranty reserves, credits issued have not been material as a percentage of net sales. The Company’s distributors do not generally carry inventories of the Company’s products. Instead, the distributors place orders with the Company at or about the time they receive orders from their customers. The Company’s shipment terms to our distributors do not provide for credits or rights of return. Because the Company’s distributors do not generally carry inventories of our products, they do not have rights to price protection or to return products. At the time the Company ships products to the distributors, the price is fixed. Subsequent to the issuance of the invoice, there are no discounts or special terms. The Company does not give the buyer the right to return the product or to receive future price concessions. The Company’s arrangements do not include vendor consideration.
    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES. The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the year ended May 31, 2017.2020. There have been no significant changes in ourthe Company’s significant accounting policies during the sixthree months ended August 31, 2020.
2. RECENT ACCOUNTING PRONOUNCEMENTS
Accounting Standards Not Yet Adopted
    Financial Instruments
    In June 2016, the FASB issued an accounting standard update (“ASU”) 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 30, 2017.2019, the accounting standard will be effective for the Company beginning in the first quarter of fiscal 2024 on a modified retrospective basis, and early adoption in fiscal 2021 is permitted.The Company does not expect a material impact of this accounting standard on its consolidated financial statements. 

3. REVENUE
Revenue recognition
    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.
    Performance obligations include sales of systems, contactors, spare parts, and services, as well as installation and training services included in customer contracts.
    A contract’s 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.
    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.
    Revenue for systems and spares is 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.
    The Company has elected the practical expedient to not assess whether a contract has a significant financing component as the Company’s standard payment terms are less than one year.
Disaggregation of revenue
    The following tables show revenues by major product categories. Within each product category, contract terms, conditions and economic factors affecting the nature, amount, timing and uncertainty around revenue recognition and cash flow are substantially similar.
    The Company’s revenues by product category are as follows (in thousands):

Contract balances
    A receivable is recognized in the period the Company delivers goods or provides services or when the Company’s 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.

    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 Condensed Consolidated Balance Sheets at the end of each reporting period as a component of deferred revenue. Contract liabilities as of August 31, 2020 and May 31, 2020 were $406,000 and $192,000, respectively. During the three months ended August 31, 2020, the Company recognized $79,000 of revenues that were included in contract liabilities as of May 31, 2020.
Remaining performance obligations
    On August 31, 2020, the Company had $128,000 of remaining performance obligations, which were comprised of deferred service contracts and extended warranty contracts not yet delivered. The Company expects to recognize approximately 66% of its remaining performance obligations as revenue in fiscal 2021, and an additional 34% in fiscal 2022 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.
Costs to obtain or fulfill a contract
    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’s 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’s products and their respective manufacturing process.
4. EARNINGS PER SHARE
    Basic earnings per share is determined using the weighted average number of common shares outstanding during the period. Diluted earnings per share is determined using the weighted average number of common shares and potential common shares (representing the dilutive effect of stock options, restricted stock units (“RSUs”), and Amended and Restated 2006 Employee Stock Purchase Plan (“ESPP”) shares) outstanding during the period using the treasury stock method.
    The following table presents the computation of basic and diluted net income (loss) per share attributable to Aehr Test Systems common shareholders (in thousands, except per share data):

    For the purpose of computing diluted earnings per share, the weighted average number of potential common shares does not include stock options with an exercise price greater than the average fair value of the Company’s common stock for the period, as the effect would be anti-dilutive. Stock options to purchase 2,594,000 shares of common stock were outstanding as of August 31, 2020, but were not included in the computation of diluted net income per share, because the inclusion of such shares would be anti-dilutive. In the three months ended August 31, 2019, potential common shares were not included in the calculation of diluted net loss per share as the effect would be anti-dilutive. As such, the numerator and the denominator used in computing both basic and diluted net loss per share for these periods are the same. Stock options to purchase 3,434,000 shares of common stock, RSUs for 20,000 shares and ESPP rights to purchase 297,000 ESPP shares were outstanding as of August 31, 2019, 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
    The Company’s 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.
    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’s pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels:
Level 1 - instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets.
Level 2 - instrument valuations are obtained from readily-available pricing sources for comparable instruments.
Level 3 - instrument valuations are obtained without observable market values and require a high level of judgment to determine the fair value.
    The following table summarizes the Company’s financial assets measured at fair value on a recurring basis as of August 31, 2020 (in thousands):

    There were no financial liabilities measured at fair value as of August 31, 2020 and May 31, 2020.
    There were no transfers between Level 1 and Level 2 fair value measurements during the three months ended August 31, 2020.
    The carrying amounts of financial instruments including cash, cash equivalents, receivables, accounts payable and certain other accrued liabilities, approximate fair value due to their short maturities.
6. ACCOUNTS RECEIVABLE, NET
Accounts receivable represent customer trade receivables. As of August 31, 2020 and May 31, 2020, there was no allowance for doubtful accounts. 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. The Company’s allowance for doubtful accounts is based upon historical experience and review of trade receivables by aging category to identify specific customers with known disputes or collection issues. Uncollectible receivables are recorded as bad debt expense when all efforts to collect have been exhausted and recoveries are recognized when they are received.

8. PRODUCT WARRANTIES
    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’s 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’s estimates, revisions to the estimated warranty liability would be required.
    The standard warranty period is one year for systems and ninety days for parts and service.
    The following is a summary of changes in the Company's liability for product warranties during the three months ended August 31, 2020 and 2019 (in thousands):

10. INCOME TAXES
    Income taxes have been provided using the liability method whereby deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and net operating loss and tax credit carryforwards measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse or the carryforwards are utilized. Valuation allowances are established when it is determined that it is more likely than not that such assets will not be realized.
    Since fiscal 2009, a full valuation allowance was established against all deferred tax assets, as management determined that it is more likely than not that certain deferred tax assets will not be realized.

The Company accounts for uncertain tax positions consistent with authoritative guidance. The guidance prescribes a “more likely than not” recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company does not expect any material change in its unrecognized tax benefits over the next twelve months. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income taxes.
    On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was passed into law. The CARES Act includes several significant business tax provisions including modification to the taxable income limitation for utilization of net operating losses (“NOLs”) incurred in 2018, 2019 and 2020 and the ability to carry back NOLs from those years for a period of up to five years, an increase to the limitation on deductibility of certain business interest expense, bonus depreciation for purchases of qualified improvement property and special deductions on certain corporate charitable contributions. The Company is currently analyzing the impact of these changes and therefore an estimate of the impact to income taxes is not yet available.
    On June 29, 2020, the Assembly Bill 85 (AB 85) was signed into law as part of the California 2020 Budget Act, which temporarily suspends the use of California net operating losses and imposes a cap on the amount of business incentive tax credits that companies can utilize against their net income for tax years 2020, 2021, and 2022. The Company analyzed the provisions of AB 85 and determined there was no impact on its provision for income taxes for the current period and will continue to evaluate the impact, if any, AB 85 may have on the Company’s condensed consolidated financial statements and disclosures.
11. LEASES
    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 condensed consolidated balance sheet, 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 sheet. The Company’s operating leases have remaining lease terms of 1 month to 3 years.
    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.
    The weighted-average remaining lease term for the Company’s operating leases was 2.9 years at August 31, 2020 and the weighted-average discount rate was 5.49%.
    The Company’s operating lease cost was $186,000 and $183,000 for the three months ended August 31, 2020 and 2019, respectively.

12. BORROWING AND FINANCING ARRANGEMENTS:
    On January 16, 2020, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with Silicon Valley Bank (“SVB”). 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 minus (b) the outstanding principal balance of any advances, under a revolving line of credit which is collateralized by all the Company’s assets except intellectual property. The borrowing base is 80% of eligible accounts, as determined by SVB from the Company’s 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’s 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. At August 31, 2020, 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 at August 31, 2020 was $159,000. There are no financial covenants in the agreement.

13. LONG-TERM DEBT:
    On April 23, 2020, the Company obtained the Paycheck Protection Program Loan (the “PPP Loan”) in the aggregate amount of $1,679,000 from SVB. The PPP Loan was evidenced by a promissory note dated April 23, 2020 (the “Note”) that matures on April 23, 2022 and bears interest at a rate of 1% per annum, payable monthly commencing on November 23, 2020. The PPP Loan proceeds were used for payroll, health care benefits, rent and utilities.
    Under the terms of the CARES Act, PPP loan recipients can apply for and be granted forgiveness for all or a portion of loans granted under the PPP. Such forgiveness will be determined, subject to limitations, based on the use of loan proceeds for payment of payroll costs, covered rent and mortgage obligations, and covered utility payments incurred by the Company. The Company intends to apply for forgiveness of the PPP Loan with respect to these covered expenses. No assurance can be given that the Company will obtain forgiveness of the amount due under the loan in whole or in part.
14. STOCK-BASED COMPENSATION
 
    Stock-based compensation expense consists of expenses for stock options, restricted stock units, or RSUs and employee stock purchase plan, or ESPP purchase rights. Stock-based compensation costexpense for stock options and ESPP purchase rights areis 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’s 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’s employee stock options have characteristics significantly different from those of publicly traded options. For RSUs, stock-based compensation cost is based on the fair value of the Company’s common stock at the grant date. All of the Company’s stock-based compensation is accounted for as an equity instrument. See NotesNote 11 and 12 in the Company’s Annual Report on Form 10-K for fiscal 20172020 filed on August 29, 201728, 2020 for further information regarding the 2016 Equity Incentive Plan (the “2016 Plan”) and the Amended and Restated 2006 ESPP.

 
    The following table summarizes the stock-based compensation expense related to the Company’s stock-based incentive plans for the three and six months ended November 30, 2017August 31, 2020 and 20162019 (in thousands):

    As of November 30, 2017August 31, 2020, and 2016,August 31, 2019, there were no stock-based compensation costsexpenses capitalized as part of inventory.
 
    During the three months ended November 30, 2017August 31, 2020 and 2016,2019, the Company recorded stock-based compensation expenses related to stock options and RSUs of $207,000$245,000 and $185,000,$150,000, respectively. During the six months ended November 30, 2017 and 2016, the Company recorded stock-based compensation related to stock options and RSUs of $408,000 and $464,000, respectively.

 
    As of November 30, 2017,August 31, 2020, the total compensation costexpense related to unvested stock-based awards under the Company’s 2016 Equity Incentive Plans,Plan, but not yet recognized, was approximately $1,316,000,$1,434,000, which is net of estimated forfeitures of $3,000.$4,000. This costexpense will be amortized on a straight-line basis over a weighted average period of approximately 2.52.9 years.
 
    During the three months ended November 30, 2017August 31, 2020 and 2016,2019, the Company recorded stock-based compensation expense related to the ESPP of $157,000$25,000 and $30,000,$49,000, respectively. During the six months ended November 30, 2017 and 2016, the Company recorded stock-based compensation related to the ESPP of $172,000 and $70,000, respectively. The increase in the three and six months ended November 30, 2017 is primarily due to employees increasing their ESPP elections during the current ESPP purchase period.
 
    As of November 30, 2017,August 31, 2020, the total compensation costexpense related to purchase rights under the ESPP but not yet recognized was approximately $49,000.$34,000. This costexpense will be amortized on a straight-line basis over a weighted average period of approximately 0.30.7 years.
 
Valuation Assumptions
 
    Valuation and Amortization Method. The Company estimates the fair value of stock options granted using the Black-Scholes option valuation model 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.
 
    Expected Term. The Company’s expected term represents the period that the Company’s 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.
 
    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 four or five years, which matches the expected term of most of the option grants, to estimate expected volatility. Volatility for each of the ESPP’s 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 costexpense recorded.

 
    Risk-Free Interest Rate. The Company bases the risk-free interest rate used in the Black-Scholes option valuation model 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.
 
    Fair Value. The fair value of the Company’s stock options granted to employees for the three and six months ended November 30, 2017August 31, 2020 and 20162019 were estimated using the following weighted average assumptions in the Black-Scholes option valuation model:

3. EARNINGS PER SHARE
    Basic earnings per share is determined using the weighted average number of common shares outstanding during the period. Diluted earnings per share is determined using the weighted average number of common shares and potential common shares (representing the dilutive effect of stock options, RSUs and ESPP shares) outstanding during the period using the treasury stock method.
    The following table presents the computation of basic and diluted net income (loss) per share attributable to the Company’s common shareholders (in thousands, except per share data):

    For the purpose of computing diluted earnings per share, the weighted average number of potential common shares does not include stock options with an exercise price greater than the average fair value of the Company’s common stock for the period, as the effect would be anti-dilutive. Stock options to purchase 263,000 shares of common stock were outstanding as of November 30, 2017 but were not included in the computation of diluted net income per share, because the inclusion of such shares would be anti-dilutive. In the three and six months ended November 30, 2016, potential common shares have not been included in the calculation of diluted net loss per share as the effect would be anti-dilutive. As such, the numerator and the denominator used in computing both basic and diluted net loss per share for this period are the same. Stock options to purchase 3,229,000 shares of common stock, RSUs for 72,000 shares and ESPP rights to purchase 246,000 ESPP shares were outstanding as of November 30, 2016, but were not included in the computation of diluted net loss per share, because the inclusion of such shares would be anti-dilutive. The 2,657,000 shares convertible under the convertible notes outstanding at November 30, 2017 and 2016 were not included in the computation of diluted net income (loss) per share, because the inclusion of such shares would be anti-dilutive.

    The unrealized loss as of November 30, 2017 is not considered other-than-temporary.
5. FAIR VALUE OF FINANCIAL INSTRUMENTS
    The Company’s 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.
    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’s pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels:
Level 1 - instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets.
Level 2 - instrument valuations are obtained from readily-available pricing sources for comparable instruments.
Level 3 - instrument valuations are obtained without observable market values and require a high level of judgment to determine the fair value.

    There were no transfers between Level 1 and Level 2 fair value measurements during the three and six months ended November 30, 2017.
    The carrying amounts of financial instruments including cash, cash equivalents, receivables, accounts payable and certain other accrued liabilities, approximate fair value due to their short maturities. Based on the borrowing rates currently available to the Company for loans with similar terms, the carrying value of the debt approximates the fair value.
    The Company has, at times, invested in debt and equity of private companies, and may do so again in the future, as part of its business strategy.
6. ACCOUNTS RECEIVABLE, NET
    Accounts receivable represent customer trade receivables and is presented net of allowances for doubtful accounts of $47,000 at November 30, 2017 and $61,000 at May 31, 2017. 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. The Company’s allowance for doubtful accounts is based upon historical experience and review of trade receivables by aging category to identify specific customers with known disputes or collection issues. Uncollectible receivables are recorded as bad debt expense when all efforts to collect have been exhausted and recoveries are recognized when they are received.

 16. DISSOLUTION OF AEHR TEST SYSTEMS JAPAN
 
    
9. PRODUCT WARRANTIESOn July 31, 2020, the Company completed the liquidation of Aehr Test Systems Japan K.K. (“ATS-Japan”), a majority owned subsidiary. Accordingly, the Company deconsolidated ATS-Japan and recognized an aggregate net gain of $2,401,000 for the period ended August 31, 2020. The net gain was mainly due to cumulative translation adjustment reclassified into earnings of $2,186,000 and the residual income tax effect in connection with the cumulative translation adjustment released into income tax benefits of $215,000.
 
 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’s 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’s estimates, revisions to the estimated warranty liability would be required.
    The standard warranty period is one year for systems and ninety days for parts and service.
    The following is a summary of changes in the Company's liability for product warranties during the three and six months ended November 30, 2017 and 2016 (in thousands):

11. INCOME TAXES
    Income taxes have been provided using the liability method whereby deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and net operating loss and tax credit carryforwards measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse or the carryforwards are utilized. Valuation allowances are established when it is determined that it is more likely than not that such assets will not be realized.
    Since fiscal 2009, a full valuation allowance was established against all deferred tax assets as management determined that it is more likely than not that certain deferred tax assets will not be realized.
    The Company accounts for uncertain tax positions consistent with authoritative guidance. The guidance prescribes a “more likely than not” recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company does not expect any material change in its unrecognized tax benefits over the next twelve months. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income taxes.

    Although the Company files U.S. federal, various state, and foreign tax returns, the Company’s only major tax jurisdictions are the United States, California, Germany and Japan. Tax years 1997 - 2016 remain subject to examination by the appropriate governmental agencies due to tax loss carryovers from those years.
   On December 22, 2017, the "Tax Cuts and Jobs Act" was signed into law, significantly impacting several sections of the Internal Revenue Code. The Company is currently analyzing the impact of these changes and therefore an estimate of the impact to income taxes is not yet available.

13. LONG-TERM DEBT
    On April 10, 2015, the Company entered into a Convertible Note Purchase and Credit Facility Agreement (the “Purchase Agreement”) with QVT Fund LP and Quintessence Fund L.P. (the “Purchasers”) providing for (a) the Company’s sale to the Purchasers of $4,110,000 in aggregate principal amount of 9.0% Convertible Secured Notes due 2017 (the “Convertible Notes”) and (b) a secured revolving loan facility (the “Credit Facility”) in an aggregate principal amount of up to $2,000,000. On August 22, 2016 the Purchase Agreement was amended to extend the maturity date of the Convertible Notes to April 10, 2019, decrease the conversion price from $2.65 per share to $2.30 per share, decrease the forced conversion price from $7.50 per share to $6.51 per share, and allow for additional equity awards.
    The Convertible Notes bear interest at an annual rate of 9.0% and will mature on April 10, 2019 unless repurchased or converted prior to that date. Interest is payable quarterly on March 1, June 1, September 1 and December 1 of each year. Debt issuance costs of $356,000, which were accreted over the term of the original loan using the effective interest rate method, were offset against the loan balance.
    The conversion price for the Convertible Notes is $2.30 per share and is subject to adjustment upon the occurrence of certain specified events. Holders may convert all or any part of the principal amount of their Convertible Notes in integrals of $10,000 at any time prior to the maturity date. Upon conversion, the Company will deliver shares of its common stock to the holder of Convertible Notes electing such conversion. The Company may not redeem the Convertible Notes prior to maturity.
    The maximum amount of $2,000,000 drawn against the Credit Facility has been converted to Convertible Notes, and at November 30, 2017 there was no remaining balance available to be drawn on the Credit Facility.
    The Company’s obligations under the Purchase Agreement are secured by substantially all of the assets of the Company.

14. RECENT ACCOUNTING PRONOUNCEMENTS
    In May 2014, as part of its ongoing efforts to assist in the convergence of GAAP and International Financial Reporting Standards (“IFRS”), the Financial Accounting Standards Board (“FASB”) issued an accounting standard update related to revenue from contracts with customers. This standard sets forth a new five-step revenue recognition model which replaces the prior revenue recognition guidance in its entirety and is intended to eliminate numerous industry-specific pieces of revenue recognition guidance that have historically existed in GAAP. The underlying principle of the new standard is that a business or other organization will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. The standard also requires more detailed disclosures and provides additional guidance for transactions that were not addressed completely in the prior accounting guidance. The standard provides alternative methods of initial adoption and will become effective for the Company beginning in the first quarter of fiscal 2019. The FASB has issued several updates to the standard which i) defer the original effective date from January 1, 2017 to January 1, 2018, while allowing for early adoption as of January 1, 2017. ii) clarify the application of the principal versus agent guidance. and iii) clarify the guidance on inconsequential and perfunctory promises and licensing. In May 2016, the FASB issued an update to address certain narrow aspects of the guidance including collectibility criterion, collection of sales taxes from customers, noncash consideration, contract modifications and completed contracts. This issuance does not change the core principle of the guidance in the initial topic issued in May 2014. In December 2016, the FASB issued updated guidance regarding revenue from contracts with customers. Some topics that could impact the Company include corrections and improvements around the following: contract costs impairment testing, disclosure of remaining performance obligations and prior period obligations, contract modifications, and contract asset versus receivable. The Company is currently evaluating the impact of adopting this new guidance on its consolidated financial statements.
    In July 2015, the FASB issued an accounting standard update that requires management to measure inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company adopted this new standard in fiscal year 2018. The adoption of this guidance does not have a significant impact on the Company’s consolidated financial statements.
    In November 2015, the FASB issued an accounting standard update related to deferred tax assets and liabilities. This standard simplifies the presentation of deferred income taxes to be classified as noncurrent in the consolidated balance sheet. The Company adopted this new standard in fiscal year 2018. The adoption of this guidance does not have a significant impact on the Company’s consolidated financial statements.
    In January 2016, the FASB issued an accounting standard update related to recognition and measurement of financial assets and financial liabilities. This standard changes accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. In addition, it clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. This standard is effective for us in fiscal year 2020. Early adoption is permitted. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements.
    In February 2016, the FASB issued authoritative guidance related to leases. This guidance requires management to present all leases greater than one year on the balance sheet as a liability to make payments and an asset as the right to use the underlying asset for the lease term. This new standard will be effective for us in fiscal year 2020, with early adoption permitted. The Company is currently evaluating the impact of adopting this new guidance on its consolidated financial statements.
    In March 2016, the FASB released an accounting standard update that simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, forfeitures, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted this new standard in fiscal year 2018. The adoption of this guidance does not have a significant impact on the Company’s consolidated financial statements.

    In June 2016, the FASB issued an accounting standard update 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 collectibility of the reported amount. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2021 on a modified retrospective basis, and early adoption in fiscal 2020 is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.
    In August 2016, the FASB issued authoritative guidance related to the classification of certain cash receipts and cash payments on the statement of cash flows. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2019 on a retrospective basis, and early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated statements of cash flows.
    In October 2016, the FASB issued an accounting standard update that requires recognition of the income tax consequences of intra-entity transfers of assets (other than inventory) at the transaction date. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2019 on a modified retrospective basis, and early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.
    In November 2016, the FASB issued authoritative guidance related to statements of cash flows. This guidance clarifies that amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of period total amounts shown on the statement of cash flows. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2019 on a retrospective basis, and early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES
 
     Our discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements,which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, assumptions and judgements, including those related to customer programs and incentives, product returns, bad debts, inventories, income taxes, financing operations, warranty obligations, and long-term service contracts. Our estimates are derived from historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Those results form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. For a discussion of the critical accounting policies, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates” in our Annual Report on Form 10-K for the fiscal year ended May 31, 2017.2020.

OFF-BALANCE SHEET ARRANGEMENTS

OVERVIEW OF CONTRACTUAL OBLIGATIONS

Item 3. QUANTITATIVEQUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS
 
    We had no holdings of derivative financial or commodity instruments as of November 30, 2017August 31, 2020 or May 31, 2017.2020.
 
    We are exposed to financial market risks, including changes in interest rates and foreign currency exchange rates. We only invest our short-term excess cash in government-backed securities with maturities of 18 months or less. We do not use any financial instruments for speculative or trading purposes. Fluctuations in interest rates would not have a material effect on our financial position, results of operations or cash flows.
 
    A majority of our revenue and capital spending is transacted in U.S. Dollars. We, however, enter into transactions in other currencies, primarily Euros and Japanese Yen.currencies. Since the price is determined at the time a purchase order is accepted, we are exposed to the risks of fluctuations in the foreign currency-U.S. Dollar exchange rates during the lengthy period from purchase order to ultimate payment. This exchange rate risk is partially offset to the extent that our subsidiaries incur expenses payable in their local currency. To date, we have not invested in instruments designed to hedge currency risks. In addition, our subsidiaries typically carry debt or other obligations due to us that may be denominated in either their local currency or U.S. Dollars. Since our subsidiaries’ financial statements are based in their local currency and our condensed consolidated financial statements are based in U.S. Dollars, we and our subsidiaries recognize foreign exchange gains or losses in any period in which the value of the local currency rises or falls in relation to the U.S. Dollar. A 10% decrease in the value of the subsidiaries’ local currency as compared with the U.S. Dollar would not be expected to result in a significant change to our net income or loss. There have been no material changes in our risk exposure since the end of the last fiscal year, nor are any material changes to our risk exposure anticipated.
 

Item 4. CONTROLSCONTROLS AND PROCEDURES
 
    EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES. Our management evaluated, with the participation of our Chief Executive Officer and our Chief Financial Officer, the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures are effective to ensure that information we are required to disclose in reports that we file or submit under the Securities and Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to management as appropriate to allow for timely decisions regarding required disclosure.

  
    CHANGES IN INTERNAL CONTROLS OVER FINANCIAL REPORTING. There was no change in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, that occurred during the period covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
 
INHERENT LIMITATIONS OF INTERNAL CONTROLS. Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within us have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving our stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
