NOTES 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 (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”) 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, 2021 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, 2021. 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.
The Company (as defined below) has been impacted by the outbreak of the novel coronavirus, known as COVID-19, which has spread throughout the world. Due to the impact of the COVID-19 pandemic on customers and customers’ customers, the Company experienced a drop in customer orders and revenues during the fiscal year ended May 31, 2021 and in the last quarter of fiscal year ended May 31, 2020. In response, the Company implemented cost reduction initiatives to mitigate operating losses, including mandatory vacation days, shutdown days, and executive staff pay reductions. The Company eliminated all cost reduction initiatives in the last quarter of the fiscal year ended May 31, 2021.
The Company will continue to monitor the situation. As of the date of this report, the Company cannot predict with certainty the potential effects the COVID-19 pandemic may have on the Company’s business and its operating results. While the overall environment remains uncertain, the Company continues to invest in priority areas with the objective of driving profitable growth over the long term.
PRINCIPLES OF CONSOLIDATION. The condensed consolidated financial statements include the accounts of Aehr Test Systems and its subsidiaries (collectively, the "Company"). On November 18, 2020, the Company established a wholly owned new subsidiary, Aehr Test Systems Philippines, which is in full operation as of March 31, 2021. All significant intercompany balances have been eliminated in consolidation. The liquidation of Aehr Test Systems Japan K.K. (“ATS-Japan”), the Company’s majority owned subsidiary, was completed on July 31, 2020 and noncontrolling interest was eliminated. See Note 16.
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.
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, 2021. There have been no significant changes in the Company’s significant accounting policies during the three months ended August 31, 2021.
2. RECENT ACCOUNTING PRONOUNCEMENTS
Accounting Standards Adopted
Income Taxes
On December 18, 2019, the FASB issued Accounting Standards Update ASU 2019-12 on Simplifying the Accounting for Income Taxes. The board decided to remove the exception to the incremental approach for intra-period tax allocation when there is a loss from continuing operations and income or gain from other items (for example discontinued operations or other comprehensive income). There are also provisions related to state taxes and calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2020. The Company has adopted ASU 2019-12 in the quarter ended August 31, 2021 with no material impact.
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 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.
The Company sells its products primarily through a direct sales force. In certain international markets, the Company sells its products through independent distributors. The Company considers revenue to be earned when all of the following criteria are met:
|
·
|
The Company has a contract with a customer that creates enforceable rights and obligations,
|
|
|
|
|
·
|
Promised performance obligations are identified,
|
|
|
|
|
·
|
The transaction price, or the amount we expect to receive, is determinable and
|
|
|
|
|
·
|
The Company has satisfied the performance obligations to the customer.
|
Transfer of control is evidenced upon passage of title and risk of loss to the customer unless we are required to provide additional services.

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, 2021 and May 31, 2021 were $3,429,000 and $288,000, respectively. During the three months ended August 31, 2021, the Company recognized $109,000 of revenues that were included in contract liabilities as of May 31, 2021.
Remaining performance obligations
On August 31, 2021, the Company had $258,000 of remaining performance obligations, which were comprised of deferred service contracts and extended warranty contracts not yet delivered. The Company expects to recognize approximately 29% of its remaining performance obligations as revenue in fiscal 2022, and an additional 71% in fiscal 2023 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 per share attributable to Aehr Test Systems common shareholders (in thousands, except per share data):

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’s common stock for the period, as the effect would be anti-dilutive. Stock options to purchase 112,000 shares of common stock were outstanding for the three months ending August 31, 2021, but were not included in the computation of diluted net income per share, because the inclusion of such shares would be anti-dilutive. Stock options to purchase 2,594,000 shares of common stock were outstanding for the three months ending 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.
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 financial liabilities measured at fair value as of August 31, 2021 and May 31, 2021.
There were no transfers between Level 1 and Level 2 fair value measurements during the three months ended August 31, 2021.
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, 2021 and May 31, 2021, 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, 2021 and 2020 (in thousands):

10. INCOME TAXES
The Company is subject to U.S federal and state and foreign income taxes as a corporation. The Company’s tax provision and the resulting effective tax rate for the interim period is determined based upon its estimated annual effective tax rate adjusted for the effect of discrete items arising in that quarter. The Company recorded a provision for income tax of $23,000 for the three months ended August 31, 2021 which consisted primarily of foreign withholding taxes and foreign income taxes. For the three months ended August 31, 2020 the Company recorded a $215,000 tax benefit related to the dissolution of its Japan subsidiary. See Note 16.
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.
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 6 months to 4 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 2.1 years at August 31, 2021 and the weighted-average discount rate was 5.43%.
The Company’s operating lease cost was $192,000 and $186,000 for the three months ended August 31, 2021 and 2020, 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.
On January 14, 2021, the Company entered into the First Amendment to Loan and Security Agreement (the “Amendment”) with Silicon Valley Bank. The Amendment, among other things, extends the Revolving Line Maturity Date to July 14, 2021; provided, however, that if the Company achieves specified operating metrics on a consolidated basis on or prior to May 31, 2021 the Amended Revolving Line Maturity Date is extended to January 13, 2022. As of August 31, 2021, the Revolving Line Maturity Date has been extended to January 13, 2022.
At August 31, 2021, the Company had no balance outstanding 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, 2021 was $1,707,000. 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 $1,678,789 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. On June 12, 2021, the Company received confirmation from SVB that on June 4, 2021, the Small Business Administration approved the Company’s PPP Loan forgiveness application for the entire PPP Loan balance of $1,678,789 and interest totaling $18,933, and the Company recognized a gain on loan forgiveness of $1,697,722.
14. STOCK-BASED COMPENSATION
Stock-based compensation expense consists of expenses for stock options, RSUs and 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’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 and is recognized as expense over the employee’s requisite service period. All of the Company’s stock-based compensation is accounted for as an equity instrument. See Note 11 in the Company’s Annual Report on Form 10-K for fiscal 2021 filed on August 27, 2021 for further information regarding the 2016 Equity Incentive Plan (the “2016 Plan”) and the ESPP.

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 six 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 expense 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 months ended August 31, 2021 and 2020 were estimated using the following weighted average assumptions in the Black-Scholes option valuation model:
