Organization And Summary Of Significant Accounting Policies | |
ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: BUSINESS: Aehr Test Systems (the Company) was incorporated in California in May 1977 and primarily designs, engineers and manufactures test and burn-in equipment used in the semiconductor industry. The Companys principal products are the Advanced Burn-In and Test System, or ABTS, the FOX full wafer contact parallel test and burn-in systems, the MAX burn-in system, WaferPak full wafer contactor, the DiePak carrier and test fixtures. LIQUIDITY: Since inception, the Company has incurred substantial cumulative losses and negative cash flows from operations. In recent years, the Company has recognized significantly lower sales levels compared to the net sales of the years immediately preceding fiscal 2009, as a result of a major customer filing bankruptcy and a slowdown in the semiconductor manufacturing industry. In response to the low levels of net sales, the Company took significant steps to minimize expense levels and to increase the likelihood that it will have sufficient cash to support operations during the slow business periods. Those steps included reductions in headcount, reduced compensation for officers and other salaried employees, Company-wide shutdowns and lower fees paid to the Board of Directors, among other spending cuts. The Company will continue to explore methods to reduce its costs as necessary. In March 2013, the Company sold 1,158,000 shares of its common stock in a private placement transaction with certain Directors and Officers of the Company and other accredited investors. The purchase price per share of the common stock sold in the private placement was $1.00, resulting in gross proceeds to the Company of $1,158,000, before offering expenses. The net proceeds after offering expenses were $1,138,000. In November 2014, the Company sold 1,065,000 shares of its common stock in a private placement transaction with certain Directors and Officers of the Company and other accredited investors. The purchase price per share of the common stock sold in the private placement was $2.431, resulting in gross proceeds to the Company of $2,589,000, before offering expenses. The net proceeds after offering expenses were $2,574,000. In August 2011, the Company entered into a working capital credit facility agreement with Silicon Valley Bank allowing the Company to borrow up to $1.5 million based upon qualified U.S. based and foreign customer receivables, and export-related inventory. In May 2012, the credit agreement was amended to increase the borrowing limit to $2.0 million. In September 2012, the credit agreement was amended to increase the borrowing limit to $2.5 million. On April 10, 2015, the Company terminated the working capital credit facility agreement with Silicon Valley Bank and 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 Companys 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. The Company received $3.8 million in net proceeds from the issuance of the Convertible Notes in fiscal 2015. In fiscal 2016 the Company drew $2.0 million against the Credit Facility. Refer to Note 9, CONVERTIBLE NOTES AND LINE OF CREDIT, for further discussion of the Credit Facility and the Convertible Notes. During fiscal 2016, 2015 and 2014, the Company experienced negative cash flow from operating activities. The Company anticipates that the existing cash balance together with income from operations, collections of existing accounts receivable, revenue from our existing backlog of products, the sale of inventory on hand, and deposits and down payments against significant orders will be adequate to meet its short-term working capital and capital equipment requirements. The Company extended the maturity date of the Convertible Notes to April 10, 2019 which improves our ability to meet current liabilities for fiscal 2017. Refer to Note 16, SUBSEQUENT EVENTS. Depending on its rate of growth and profitability, and its ability to obtain significant orders with down payments, the Company may require additional equity or debt financing to meet its working capital requirements or capital equipment needs. There can be no assurance that additional financing will be available when required, or if available, that such financing can be obtained on terms satisfactory to the Company. CONSOLIDATION AND EQUITY INVESTMENTS: 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. Equity investments in which the Company holds an equity interest less than 20 percent and over which the Company does not have significant influence are accounted for using the cost method. Dividends received from investees accounted for using the cost method are included in other (expense) income, net on the Consolidated Statements of Operations. FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS: Assets and liabilities of the Companys foreign subsidiaries and a branch office are translated into U.S. Dollars from their functional currencies of Japanese Yen, Euros 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 equity (deficit). 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 12 for the detail of foreign exchange transaction gains and losses for all periods presented. USE OF ESTIMATES: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 Companys consolidated financial statements include allowance for doubtful accounts, valuation of inventory at the lower of cost or market, and warranty reserves. CASH EQUIVALENTS AND INVESTMENTS: Cash equivalents consist of money market instruments purchased with an original maturity of three months or less. These investments are reported at fair value. FAIR VALUE OF FINANCIAL INSTRUMENTS AND MEASUREMENT: The Companys 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 entitys 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 Companys financial assets measured at fair value on a recurring basis as of May 31, 2016 (in thousands): Balance as of May 31, 2016 Level 1 Level 2 Level 3 Money market funds $ 1 $ 1 $ $ Certificate of deposit 50 50 Assets $ 51 $ 1 $ 50 $ The following table summarizes the Companys financial assets measured at fair value on a recurring basis as of May 31, 2015 (in thousands): Balance as of May 31, 2015 Level 1 Level 2 Level 3 Money market funds $ 4,650 $ 4,650 $ $ Certificate of deposit 50 50 Assets $ 4,700 $ 4,650 $ 50 $ There were no financial liabilities measured at fair value as of May 31, 2016 and 2015. There were no transfers between Level 1 and Level 2 fair value measurements during the fiscal year ended May 31, 2016 and 2015. Financial instruments include cash, cash equivalents, receivables, accounts payable and certain other accrued liabilities. The fair value of cash, cash equivalents, receivables, accounts payable and certain other accrued expenses are valued at their carrying value, which approximates fair value due to their short maturities. 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. ACCOUNTS RECEIVABLE AND 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. 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. No significant adjustments to the allowance for doubtful accounts were recorded during the years ended May 31, 2016, 2015 or 2014. CONCENTRATION OF CREDIT RISK: The Company sells its products primarily to semiconductor manufacturers in North America, Asia, and Europe. As of May 31, 2016, approximately 7%, 68% and 25% of gross accounts receivable were from customers located in Asia, Europe and North America, respectively. As of May 31, 2015, approximately 70%, 3% and 27% of gross accounts receivable were from customers located in Asia, Europe and North America, respectively. One customer accounted for 67% of gross accounts receivable as of May 31, 2016. Two customers accounted for 41% and 32% of gross accounts receivable as of May 31, 2015. Two customers accounted for 47% and 32% of net sales in fiscal 2016. Two customers accounted for 45% and 11% of net sales in fiscal 2015. 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. The Companys cash and cash equivalents are generally deposited with major financial institutions in the United States, Japan, Germany and Taiwan. The Company invests its excess cash in money market funds. The money market funds bear the risk associated with each fund. The money market funds have variable interest rates. The Company has not experienced any material losses on its money market funds or short-term cash deposits. CONCENTRATION OF SUPPLY RISK: The Company relies on subcontractors to manufacture many of the components and subassemblies used in its products. Quality or performance failures of the Companys products or changes in its manufacturers financial or business condition could disrupt the Companys 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 Companys 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. INVENTORIES: Inventories include material, labor and overhead, and are stated at the lower of cost (first-in, first-out method) or market. Provisions for excess, obsolete and unusable inventories are made after managements evaluation of future demand and market conditions. The Company adjusts inventory balances to approximate the lower of its manufacturing costs or market 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 product revenue in the period the revision is made. PROPERTY AND EQUIPMENT: 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: Furniture and fixtures . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .2 to 6 years Machinery and equipment. . . . . . . . . . . . . . . . . . . . . . . . . . . . .3 to 6 years Test equipment. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 to 6 years 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 are 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. The Company has adopted this guidance effective with the first quarter of fiscal 2012. During the first quarter of fiscal 2013, the Company entered into an agreement with a customer to develop a next generation system. 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 vendors 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. 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 licensees report related to its usage of the licensed intellectual property or upon payment by the licensee. The Companys 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 Companys distributors do not generally carry inventories of the Companys products. Instead, the distributors place orders with the Company at or about the time they receive orders from their customers. The Companys shipment terms to our distributors do not provide for credits or rights of return. Because the Companys 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 Companys arrangements do not include vendor consideration. PRODUCT DEVELOPMENT COSTS AND CAPITALIZED SOFTWARE: 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 Companys 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 2016, 2015 and 2014. IMPAIRMENT OF LONG-LIVED ASSETS: 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 assets carrying value to determine if a write-down is required. ADVERTISING COSTS: The Company expenses all advertising costs as incurred and the amounts were not material for all periods presented. SHIPPING AND HANDLING OF PRODUCTS: 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. 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. A full valuation allowance was established against all deferred tax assets, as management determined that it is more likely than not that deferred tax assets will not be realized, as of May 31, 2016 and 2015. 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 Companys 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. 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 cost for stock options and ESPP purchase rights are 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 employees 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 Companys employee stock options have characteristics significantly different from those of publicly traded options. All of the Companys stock-based compensation is accounted for as an equity instrument. The following table summarizes compensation costs related to the Companys stock-based compensation for the years ended May 31, 2016, 2015 and 2014 (in thousands, except per share data): Year Ended May 31, 2016 2015 2014 Stock-based compensation in the form of stock options, RSUs, and ESPP purchase rights, included in: Cost of sales $ 87 $ 70 $ 43 Selling, general and administrative 723 726 643 Research and development 206 201 167 Net effect on net (loss) income $ 1,016 $ 997 $ 853 Effect on net (loss) income per share: Basic $ 0.08 $ 0.08 $ 0.08 Diluted $ 0.08 $ 0.08 $ 0.07 During fiscal 2016, 2015 and fiscal 2014, the Company recorded stock-based compensation related to stock options and restricted stock units of $894,000, $857,000 and $723,000, respectively. As of May 31, 2016, the total compensation cost related to unvested stock-based awards under the Companys 1996 Stock Option Plan and 2006 Equity Incentive Plan, but not yet recognized, was $1,102,000 which is net of estimated forfeitures of $3,000. This cost will be amortized on a straight-line basis over a weighted average period of approximately 2.1 years. During fiscal 2016, 2015 and fiscal 2014, the Company recorded stock-based compensation related to its ESPP of $122,000, $140,000 and $130,000, respectively. As of May 31, 2016, 2015 and 2014, stock-based compensation costs of $0, $20,000 and $24,000, respectively, were capitalized as part of inventory. As of May 31, 2016, the total compensation cost related to purchase rights under the ESPP but not yet recognized was $138,000. This cost will be amortized on a straight-line basis over a weighted average period of approximately 1.2 years. Valuation Assumptions 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. Expected Term. The Companys expected term represents the period that the Companys 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. Expected 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 years, which matches the expected term of most of the option grants, to estimate expected volatility. Volatility for each of the ESPPs 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 cost recorded. Dividends. The Company has never paid any cash dividends on its common stock and does not anticipate paying any cash dividends in the foreseeable future. Consequently, the Company uses an expected dividend yield of zero in the Black-Scholes option valuation method. 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. Estimated Forfeitures. When estimating forfeitures, the Company considers voluntary termination behavior as well as analysis of actual option forfeitures. Fair Value. The fair values of the Companys stock options granted to employees shares in fiscal 2016, 2015 and 2014 were estimated using the following weighted average assumptions in the Black-Scholes option valuation method: Year Ended May 31, 2016 2015 2014 Option plan shares Expected term (in years) 4 4 4 Volatility 0.86 0.90 0.95 Expected dividend $ 0.00 $ 0.00 $ 0.00 Risk-free interest rates 1.21 % 1.20 % 1.39 % Weighted-average grant date fair value $ 1.31 $ 1.52 $ 1.09 The fair value of our ESPP purchase rights for the fiscal 2016, 2015 and 2014 was estimated using the following weighted-average assumptions: Year End May 31, 2016 2015 2014 Employee stock purchase plan shares Expected term (in years) 0.5 2.0 0.5 2.0 0.5 2.0 Volatility 0.64 0.74 0.55 0.83 0.86 1.00 Expected dividend $ 0.00 $ 0.00 $ 0.00 Risk-free interest rates 0.40%0.76% 0.04%0.55% 0.04%0.44% Weighted-average grant date fair value $ 0.80 $ 1.43 $ 1.34 During the fiscal years ended May 31, 2016, 2015 and 2014, ESPP purchase rights of 304,000, 222,000, and 172,000 shares, respectively, were granted. Total ESPP shares issued during the fiscal years ended May 31, 2016, 2015, and 2014 were 86,000, 87,000, and 120,000 shares, respectively. As of May 31, 2016 there were 182,000 ESPP shares available for issuance. EARNINGS PER SHARE (EPS): 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, and employee stock purchase plan shares) outstanding during the period using the treasury stock method. The following table presents the computation of basic and diluted net (loss) income per share attributable to Aehr Test Systems common shareholders (in thousands, except per share data): Year Ended May 31, 2016 2015 2014 Numerator: Net (loss) income $ (6,785 ) $ (6,647 ) $ 422 Denominator for basic net (loss) income per share: Weighted-average shares outstanding 13,091 12,047 10,877 Shares used in basic net (loss) income per share calculation 13,091 12,047 10,877 Effect of dilutive securities 1,012 Denominator for diluted net (loss) income per share 13,091 12,047 11,889 Basic net (loss) income per share $ (0.52 ) $ (0.55 ) $ 0.04 Diluted net (loss) income per share $ (0.52 ) $ (0.55 ) $ 0.04 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 Companys common stock for the period, as the effect would be anti-dilutive. In the fiscal years ended May 31, 2016 and 2015, 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 these periods are the same. Stock options to purchase 3,201,000, 3,686,000, and 301,000 shares of common stock were outstanding on May 31, 2016, 2015 and 2014, respectively, but were not included in the computation of diluted net (loss) income per share, because the inclusion of such shares would be anti-dilutive. ESPP rights to purchase 304,000, 175,000 and 131,000 ESPP shares were outstanding on May 31, 2016, 2015 and 2014, respectively, but were not included in the computation of diluted net (loss) income per share, because the inclusion of such shares would be anti-dilutive. RSUs for 35,000 shares were outstanding at May 31, 2016 but not included in the computation of diluted net (loss) income per share, because the inclusion of such shares would be anti-dilutive. The shares convertible under the Convertible Notes outstanding at May 31, 2016 were not included in the computation of diluted net (loss) income per share, because the inclusion of such shares would be anti-dilutive. COMPREHENSIVE (LOSS) INCOME: Comprehensive (loss) income generally represents all changes in shareholders equity (deficit) except those resulting from investments or contributions by shareholders. Unrealized gains and losses on foreign currency translation adjustments are included in the Companys components of comprehensive (loss) income, which are excluded from net (loss) income. Comprehensive (loss) income is included in the statements of shareholders equity (deficit) and comprehensive (loss) income. RECLASSIFICATION Certain reclassifications have been made to the consolidated financial statements to conform to the current period presentation. These reclassifications did not result in any change in previously reported net loss, total assets or shareholders equity (deficit). RECENT ACCOUNTING PRONOUNCEMENTS: In May 2014, as part of its ongoing efforts to assist in the convergence of US GAAP and International Financial Reporting Standards (IFRS), the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606). The new guidance 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 US GAAP. The underlying principle of the new standard is that a business or other organization will recognize revenue to reflect 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 ASU provides alternative methods of initial adoption and will become effective for us 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 (ASU 2015-14). ii) clarify the application of the principal versus agent guidance (ASU 2016-08). and iii) clarify the guidance on inconsequential and perfunctory promises and licensing (ASU 2016-10). In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606) Narrow-Scope Improvements and Practical Expedients, to address certain narrow aspects of the guidance including collectibility criterion, collection of sales taxes from customers, noncash consideration, contract |

Product Warranties | 5. 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 Companys 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 Companys 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. Following is a summary of changes in the Companys liability for product warranties during the fiscal years ended May 31, 2016 and 2015 (in thousands): May 31, 2016 2015 Balance at the beginning of the year $ 137 $ 223 Accruals for warranties issued during the year 334 150 Settlement made during the year (in cash or in kind) (316 ) (236 ) Balance at the end of the year $ 155 $ 137 The accrued warranty balance is included in accrued expenses on the consolidated balance sheets. |

INCOME TAXES: Domestic and foreign components of (loss) income before income tax (expense) benefit are as follows (in thousands): Year Ended May 31, 2016 2015 2014 Domestic $ (6,794 ) $ (6,871 ) $ 438 Foreign 19 258 (31 ) $ (6,775 ) $ (6,613 ) $ 407 The income tax (expense) benefit consists of the following (in thousands): Year Ended May 31, 2016 2015 2014 Federal income taxes: Current $ $ $ Deferred State income taxes: Current 3 (19 ) (30 ) Deferred Foreign income taxes: Current (13 ) (15 ) 45 Deferred $ (10 ) $ (34 ) $ 15 The Companys effective tax rate differs from the U.S. federal statutory tax rate, as follows: Year Ended May 31, 2016 2015 2014 U.S. federal statutory tax rate 34.0 % 34.0 % 34.0 % State taxes, net of federal tax effect (0.2 ) 4.7 Foreign rate differential 0.2 1.4 (11.9 ) Stock-based compensation (3.8 ) (2.2 ) 34.5 Research and development credit 2.1 1.1 (20.5 ) Change in valuation allowance (32.5 ) (34.4 ) (45.8 ) Other (0.2 ) (0.2 ) 1.3 Effective tax rate (0.2 )% (0.5 )% (3.7 )% The components of the net deferred tax assets are as follows (in thousands): Year Ended May 31, 2016 2015 Net operating losses $ 16,643 $ 15,063 Credit carryforwards 4,430 3,946 Inventory reserves 1,064 1,429 Reserves and accruals 1,606 2,809 Other 885 960 24,628 24,207 Less: Valuation allowance (24,628 ) (24,207 ) Net deferred tax assets $ $ The valuation allowance increased by $421,000 during fiscal 2016, increased by $2,223,000 during fiscal 2015, and decreased by $206,000 during fiscal 2014. As of May 31, 2016 and 2015, the Company concluded that it is more likely than not that the deferred tax assets will not be realized and therefore provided a full valuation allowance against the deferred tax assets. The Company will continue to evaluate the need for a valuation allowance against its deferred tax assets on a quarterly basis. At May 31, 2016, the Company had federal and state net operating loss carryforwards of $45,272,000 and $31,110,000, respectively. The federal and state net operating loss carryforwards will begin to expire in 2024 and began expiring in 2015, respectively. At May 31, 2016, the Company also had federal and state research and development tax credit carryforwards of $1,769,000 and $4,894,000, respectively. The federal credit carryforward will begin to expire in 2019, and the California credit will carryforward indefinitely. These carryforwards may be subject to certain limitations on annual utilization in case of a change in ownership, as defined by tax law. The Company also has alternative minimum tax credit carryforwards of $91,000 for federal tax purposes and $34,000 for state purposes. The credits may be used to offset regular tax and do not expire. The Company has made no provision for U.S. income taxes on undistributed earnings of certain foreign subsidiaries because it is the Companys 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. Determination of the amount of unrecognized deferred income tax liability related to these earnings is not practicable. Foreign net operating loss carryforwards of $848,000 are available to reduce future foreign taxable income. The foreign net operating losses will begin to expire in 2018. 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. The aggregate changes in the balance of gross unrecognized tax benefits are as follows (in thousands): Beginning balance as of May 31, 2013 $ 1,007 Decreases related to prior year tax positions Decreases related to lapse of statute of limitations (34 ) Balance at May 31, 2014 $ 973 Decreases related to prior year tax positions Decreases related to lapse of statute of limitations (54 ) Balance at May 31, 2015 $ 919 Decreases related to prior year tax positions (124 ) Decreases related to lapse of statute of limitations (6 ) Balance at May 31, 2016 $ 789 The ending balance of $789,000 of unrecognized tax benefits as of May 31, 2016, if recognized, would not impact the effective tax rate. Although the Company files U.S. federal, various state, and foreign tax returns, the Companys 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. |

CONVERTIBLE NOTES AND LINE OF CREDIT | 9. CONVERTIBLE NOTES AND LINE OF CREDIT: 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 Companys 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. Refer to Note 16, SUBSEQUENT EVENTS. 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 represent an effective interest rate of 4.3%, were offset against the loan balance and are amortized over the life of loan. During fiscal years ended May 31, 2016 and 2015, $177,000 and $31,000, respectively, of amortization costs were recognized as interest expense. The conversion price for the Convertible Notes is $2.30 per share of the Companys common stock and is subject to adjustment upon the occurrence of certain specified events (as adjusted, the Conversion Price). 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. Advances under the Credit Facility must be supported by outstanding valid purchase orders at least equal to the amount of the requested drawdown plus the principal amount of all outstanding 5.0% Notes as defined under the Purchase Agreement. Advances will bear interest at an annual rate of 5.0%. Each advance under the Credit Facility and any accrued and unpaid interest thereon must be repaid within 90 days from the date on which such advance is made. Unless paid in full at maturity, amounts owing under the credit facility may be converted by the holder into Convertible Notes. Advances under the Credit Facility may be prepaid without any prepayment premium or penalty and may be reborrowed (unless converted into Convertible Notes). The Companys obligations under the Purchase Agreement are secured by substantially all of the assets of the Company. During fiscal 2016, the Company borrowed $2,000,000 against the credit facility. During fiscal 2016, $900,000 of the borrowing was converted into Convertible Notes upon maturity. As of May 31, 2016 and 2015, the Company had a balance of $1,100,000 and zero against the Credit Facility, respectively. The balance available to borrow under the Credit Facility as of May 31, 2016 was zero. Upon maturity in July 2016, the $1,100,000 balance of the Credit Facility was converted into Convertible Notes. The May 31, 2016 balance was reclassified to Convertible Notes with the amendment of the Purchase Agreement. Refer to Note 16, SUBSEQUENT EVENTS.

CAPITAL STOCK | 10. CAPITAL STOCK: STOCK OPTIONS: In October 1996, the Companys Board of Directors approved the 1996 Stock Option Plan (the Stock Plan), which provided for granting of incentive and non-qualified stock options to our employees and directors. The Stock Plan provides that qualified options be granted at an exercise price equal to the fair market value at the date of grant, as determined by the Board of Directors (85% of fair market value in the case of non-statutory options and purchase rights and 110% of fair market value in certain circumstances). Options generally expire within five years from date of grant. Most options become exercisable in increments over a four-year period from the date of grant. In October 2006, the Companys 2006 Equity Incentive Plan and 2006 Employee Stock Purchase Plan (2006 Plans) were approved by the shareholders, which provide for granting of incentive stock options, nonstatutory stock options, restricted stock, restricted stock units, stock appreciation rights, performance units, performance shares and other stock or cash awards as the Companys Board of Directors may determine. A total of 5,450,000 shares of common stock have been reserved for issuance under the Companys 2006 Equity Incentive Plan. Options granted under the 2006 Equity Incentive Plan are generally for periods not to exceed ten years (five years if the option is granted to a 10% stockholder) and are granted at the fair market value of the stock at the date of grant as determined by the Board of Directors. The 2006 Plans respectively replace the Companys Amended and Restated 1996 Stock Option Plan, which would otherwise have expired in 2006; and the Companys 1997 Employee Stock Purchase Plan, which would have otherwise expired in 2007. As of May 31, 2016, out of the 5,083,000 shares authorized for grant under the 2006 Equity Incentive Plan, approximately 3,201,000 shares were outstanding.

Employee Benefit Plans | |
EMPLOYEE BENEFIT PLANS | 11. EMPLOYEE BENEFIT PLANS: EMPLOYEE STOCK OWNERSHIP PLAN: 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 Companys 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 Plan). The stock bonus plan was converted to an employee stock ownership plan (ESOP) to enable the Plan to better comply with changes in the law regarding Company stock. Individuals 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 $60,000 per year were authorized for the plan during fiscal 2016, 2015 and 2014. The contribution amounts are recorded as compensation expense, in the period authorized and included in accrued expenses, in the period authorized. Contributions of 25,000 shares were made to the ESOP during fiscal 2016 for fiscal 2015. Contributions of 26,548 shares were made to the ESOP during fiscal 2015 for fiscal 2014. Contributions of 41,666 shares were made to the ESOP during fiscal 2014 for fiscal 2013. The contribution for fiscal 2016 will be made in fiscal 2017. Shares held in the ESOP are included in the EPS calculation. 401(K) PLAN: The Company maintains a defined contribution savings plan (the 401(k) Plan) 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 2016, 2015 and 2014. EMPLOYEE STOCK PURCHASE PLAN: In October 2006, the Companys shareholders approved the 2006 Employee Stock Purchase Plan, or 2006 Purchase Plan. The 2006 Purchase Plan replaced the 1997 Employee Stock Purchase Plan which would have otherwise expired in 2007. A total of 1,150,000 shares of the Companys common stock were reserved for issuance under the 2006 Purchase Plan. The 2006 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. The first exercise date under the 2006 Purchase Plan was April 1, 2007. 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 2006 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 Companys common stock at either the first day of an offering period or the last day of the purchase period. If a participants 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 2006 Purchase Plan. The maximum number of shares a participant may purchase during a single purchase period is 3,000 shares. For the years ended May 31, 2016, 2015 and 2014, approximately 86,000, 87,000 and 120,000 shares of common stock, respectively, were issued under the plans. To date, 968,000 shares have been issued under the 2006 Purchase Plan. |

Commitments and Contingencies Disclosure [Abstract] | |
COMMITMENTS AND CONTINGENCIES | 15. COMMITMENTS AND CONTINGENCIES: COMMITMENTS The Company leases most of its manufacturing and office space under operating leases. The Company entered into non-cancelable operating lease agreements for its United States manufacturing and office facilities and maintains equipment under non-cancelable operating leases in Germany. The Companys principal administrative and production facilities are located in Fremont, California, in a 51,289 square foot building. The Companys lease was renewed in November, 2014 and expires in June 2018. The Company has an option to extend the lease for an additional three year period at rates to be determined. The Companys facility in Japan is located in a 418 square foot office in Tokyo under a cancellable lease which expires in June 2019. The Company also maintains a 1,585 square foot warehouse in Yamanashi under a lease which expires in November 2016. The Company leases a sales and support office in Utting, Germany. The lease, which began February 1, 1992 and expires on January 31, 2018, contains an automatic twelve months renewal, at rates to be determined, if no notice is given prior to six months from expiry. Under the lease agreements, the Company is responsible for payments of utilities, taxes and insurance. Minimum annual rentals payments under non-cancellable operating leases in each of the next five fiscal years and thereafter are as follows (in thousands): Years Ending May 31, 2017 $ 488 2018 485 2019 39 2020 2021 Thereafter Total $ 1,012 Rental expense for the years ended May 31, 2016, 2015 and 2014 was $499,000, $554,000 and $562,000, respectively. At May 31, 2016 and 2015, the Company had a $50,000 certificate of deposit 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. PURCHASE OBLIGATIONS 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, 2016, the Company had $554,000 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. CONTINGENCIES The Company is, from time to time, 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 Companys consolidated financial position, results of operations or cash flows. In the normal course of business to facilitate sales of its products, the Company indemnifies other parties, including customers, with respect to certain matters. The Company has agreed to hold the other party harmless 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 Companys bylaws contain similar indemnification obligations to the Companys agents. 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 Companys operating results, financial position or cash flows. |

1. ORGANIZATION AND SUMMARY O25
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 12 Months Ended |
May 31, 2016 | |
Accounting Policies [Abstract] | |
BUSINESS: | BUSINESS: Aehr Test Systems (the Company) was incorporated in California in May 1977 and primarily designs, engineers and manufactures test and burn-in equipment used in the semiconductor industry. The Companys principal products are the Advanced Burn-In and Test System, or ABTS, the FOX full wafer contact parallel test and burn-in systems, the MAX burn-in system, WaferPak full wafer contactor, the DiePak carrier and test fixtures. |
LIQUIDITY: | LIQUIDITY: Since inception, the Company has incurred substantial cumulative losses and negative cash flows from operations. In recent years, the Company has recognized significantly lower sales levels compared to the net sales of the years immediately preceding fiscal 2009, as a result of a major customer filing bankruptcy and a slowdown in the semiconductor manufacturing industry. In response to the low levels of net sales, the Company took significant steps to minimize expense levels and to increase the likelihood that it will have sufficient cash to support operations during the slow business periods. Those steps included reductions in headcount, reduced compensation for officers and other salaried employees, Company-wide shutdowns and lower fees paid to the Board of Directors, among other spending cuts. The Company will continue to explore methods to reduce its costs as necessary. In March 2013, the Company sold 1,158,000 shares of its common stock in a private placement transaction with certain Directors and Officers of the Company and other accredited investors. The purchase price per share of the common stock sold in the private placement was $1.00, resulting in gross proceeds to the Company of $1,158,000, before offering expenses. The net proceeds after offering expenses were $1,138,000. In November 2014, the Company sold 1,065,000 shares of its common stock in a private placement transaction with certain Directors and Officers of the Company and other accredited investors. The purchase price per share of the common stock sold in the private placement was $2.431, resulting in gross proceeds to the Company of $2,589,000, before offering expenses. The net proceeds after offering expenses were $2,574,000. In August 2011, the Company entered into a working capital credit facility agreement with Silicon Valley Bank allowing the Company to borrow up to $1.5 million based upon qualified U.S. based and foreign customer receivables, and export-related inventory. In May 2012, the credit agreement was amended to increase the borrowing limit to $2.0 million. In September 2012, the credit agreement was amended to increase the borrowing limit to $2.5 million. On April 10, 2015, the Company terminated the working capital credit facility agreement with Silicon Valley Bank and 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 Companys 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. The Company received $3.8 million in net proceeds from the issuance of the Convertible Notes in fiscal 2015. In fiscal 2016 the Company drew $2.0 million against the Credit Facility. Refer to Note 9, CONVERTIBLE NOTES AND LINE OF CREDIT, for further discussion of the Credit Facility and the Convertible Notes. During fiscal 2016, 2015 and 2014, the Company experienced negative cash flow from operating activities. The Company anticipates that the existing cash balance together with income from operations, collections of existing accounts receivable, revenue from our existing backlog of products, the sale of inventory on hand, and deposits and down payments against significant orders will be adequate to meet its short-term working capital and capital equipment requirements. The Company extended the maturity date of the Convertible Notes to April 10, 2019 which improves our ability to meet current liabilities for fiscal 2017. Refer to Note 16, SUBSEQUENT EVENTS. Depending on its rate of growth and profitability, and its ability to obtain significant orders with down payments, the Company may require additional equity or debt financing to meet its working capital requirements or capital equipment needs. There can be no assurance that additional financing will be available when required, or if available, that such financing can be obtained on terms satisfactory to the Company. |
CONSOLIDATION AND EQUITY INVESTMENTS: | CONSOLIDATION AND EQUITY INVESTMENTS: 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. Equity investments in which the Company holds an equity interest less than 20 percent and over which the Company does not have significant influence are accounted for using the cost method. Dividends received from investees accounted for using the cost method are included in other (expense) income, net on the Consolidated Statements of Operations. |
FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS: | FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS: Assets and liabilities of the Companys foreign subsidiaries and a branch office are translated into U.S. Dollars from their functional currencies of Japanese Yen, Euros 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 equity (deficit). 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 12 for the detail of foreign exchange transaction gains and losses for all periods presented. |
USE OF ESTIMATES: | USE OF ESTIMATES: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 Companys consolidated financial statements include allowance for doubtful accounts, valuation of inventory at the lower of cost or market, and warranty reserves. |
CASH EQUIVALENTS AND INVESTMENTS: | CASH EQUIVALENTS AND INVESTMENTS: Cash equivalents consist of money market instruments purchased with an original maturity of three months or less. These investments are reported at fair value. |
FAIR VALUE OF FINANCIAL INSTRUMENTS AND MEASUREMENT: | FAIR VALUE OF FINANCIAL INSTRUMENTS AND MEASUREMENT: The Companys 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 entitys 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 Companys financial assets measured at fair value on a recurring basis as of May 31, 2016 (in thousands): Balance as of May 31, 2016 Level 1 Level 2 Level 3 Money market funds $ 1 $ 1 $ $ Certificate of deposit 50 50 Assets $ 51 $ 1 $ 50 $ The following table summarizes the Companys financial assets measured at fair value on a recurring basis as of May 31, 2015 (in thousands): Balance as of May 31, 2015 Level 1 Level 2 Level 3 Money market funds $ 4,650 $ 4,650 $ $ Certificate of deposit 50 50 Assets $ 4,700 $ 4,650 $ 50 $ There were no financial liabilities measured at fair value as of May 31, 2016 and 2015. There were no transfers between Level 1 and Level 2 fair value measurements during the fiscal year ended May 31, 2016 and 2015. Financial instruments include cash, cash equivalents, receivables, accounts payable and certain other accrued liabilities. The fair value of cash, cash equivalents, receivables, accounts payable and certain other accrued expenses are valued at their carrying value, which approximates fair value due to their short maturities. 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. |
ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS: | ACCOUNTS RECEIVABLE AND 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. 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. No significant adjustments to the allowance for doubtful accounts were recorded during the years ended May 31, 2016, 2015 or 2014. |
CONCENTRATION OF CREDIT RISK: | CONCENTRATION OF CREDIT RISK: The Company sells its products primarily to semiconductor manufacturers in North America, Asia, and Europe. As of May 31, 2016, approximately 7%, 68% and 25% of gross accounts receivable were from customers located in Asia, Europe and North America, respectively. As of May 31, 2015, approximately 70%, 3% and 27% of gross accounts receivable were from customers located in Asia, Europe and North America, respectively. One customer accounted for 67% of gross accounts receivable as of May 31, 2016. Two customers accounted for 41% and 32% of gross accounts receivable as of May 31, 2015. Two customers accounted for 47% and 32% of net sales in fiscal 2016. Two customers accounted for 45% and 11% of net sales in fiscal 2015. 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. The Companys cash and cash equivalents are generally deposited with major financial institutions in the United States, Japan, Germany and Taiwan. The Company invests its excess cash in money market funds. The money market funds bear the risk associated with each fund. The money market funds have variable interest rates. The Company has not experienced any material losses on its money market funds or short-term cash deposits. |
CONCENTRATION OF SUPPLY RISK: | CONCENTRATION OF SUPPLY RISK: The Company relies on subcontractors to manufacture many of the components and subassemblies used in its products. Quality or performance failures of the Companys products or changes in its manufacturers financial or business condition could disrupt the Companys 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 Companys 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. |
INVENTORIES: | INVENTORIES: Inventories include material, labor and overhead, and are stated at the lower of cost (first-in, first-out method) or market. Provisions for excess, obsolete and unusable inventories are made after managements evaluation of future demand and market conditions. The Company adjusts inventory balances to approximate the lower of its manufacturing costs or market 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 product revenue in the period the revision is made. |
PROPERTY AND EQUIPMENT: | PROPERTY AND EQUIPMENT: 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: Furniture and fixtures . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .2 to 6 years Machinery and equipment. . . . . . . . . . . . . . . . . . . . . . . . . . . . .3 to 6 years Test equipment. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 to 6 years |
REVENUE RECOGNITION: | 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 are 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. The Company has adopted this guidance effective with the first quarter of fiscal 2012. During the first quarter of fiscal 2013, the Company entered into an agreement with a customer to develop a next generation system. 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 vendors 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. 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 licensees report related to its usage of the licensed intellectual property or upon payment by the licensee. The Companys 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 Companys distributors do not generally carry inventories of the Companys products. Instead, the distributors place orders with the Company at or about the time they receive orders from their customers. The Companys shipment terms to our distributors do not provide for credits or rights of return. Because the Companys 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 Companys arrangements do not include vendor consideration. |
PRODUCT DEVELOPMENT COSTS AND CAPITALIZED SOFTWARE: | PRODUCT DEVELOPMENT COSTS AND CAPITALIZED SOFTWARE: 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 Companys 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 2016, 2015 and 2014. |
IMPAIRMENT OF LONG-LIVED ASSETS: | IMPAIRMENT OF LONG-LIVED ASSETS: 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 assets carrying value to determine if a write-down is required. |
ADVERTISING COSTS: | ADVERTISING COSTS: The Company expenses all advertising costs as incurred and the amounts were not material for all periods presented. |
SHIPPING AND HANDLING OF PRODUCTS: | SHIPPING AND HANDLING OF PRODUCTS: 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. |
INCOME TAXES: | 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. A full valuation allowance was established against all deferred tax assets, as management determined that it is more likely than not that deferred tax assets will not be realized, as of May 31, 2016 and 2015. 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 Companys 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. |
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 cost for stock options and ESPP purchase rights are 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 employees 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 Companys employee stock options have characteristics significantly different from those of publicly traded options. All of the Companys stock-based compensation is accounted for as an equity instrument. The following table summarizes compensation costs related to the Companys stock-based compensation for the years ended May 31, 2016, 2015 and 2014 (in thousands, except per share data): Year Ended May 31, 2016 2015 2014 Stock-based compensation in the form of stock options, RSUs, and ESPP purchase rights, included in: Cost of sales $ 87 $ 70 $ 43 Selling, general and administrative 723 726 643 Research and development 206 201 167 Net effect on net (loss) income $ 1,016 $ 997 $ 853 Effect on net (loss) income per share: Basic $ 0.08 $ 0.08 $ 0.08 Diluted $ 0.08 $ 0.08 $ 0.07 During fiscal 2016, 2015 and fiscal 2014, the Company recorded stock-based compensation related to stock options and restricted stock units of $894,000, $857,000 and $723,000, respectively. As of May 31, 2016, the total compensation cost related to unvested stock-based awards under the Companys 1996 Stock Option Plan and 2006 Equity Incentive Plan, but not yet recognized, was $1,102,000 which is net of estimated forfeitures of $3,000. This cost will be amortized on a straight-line basis over a weighted average period of approximately 2.1 years. During fiscal 2016, 2015 and fiscal 2014, the Company recorded stock-based compensation related to its ESPP of $122,000, $140,000 and $130,000, respectively. As of May 31, 2016, 2015 and 2014, stock-based compensation costs of $0, $20,000 and $24,000, respectively, were capitalized as part of inventory. As of May 31, 2016, the total compensation cost related to purchase rights under the ESPP but not yet recognized was $138,000. This cost will be amortized on a straight-line basis over a weighted average period of approximately 1.2 years. Valuation Assumptions 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. Expected Term. The Companys expected term represents the period that the Companys 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. Expected 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 years, which matches the expected term of most of the option grants, to estimate expected volatility. Volatility for each of the ESPPs 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 cost recorded. Dividends. The Company has never paid any cash dividends on its common stock and does not anticipate paying any cash dividends in the foreseeable future. Consequently, the Company uses an expected dividend yield of zero in the Black-Scholes option valuation method. 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. Estimated Forfeitures. When estimating forfeitures, the Company considers voluntary termination behavior as well as analysis of actual option forfeitures. Fair Value. The fair values of the Companys stock options granted to employees shares in fiscal 2016, 2015 and 2014 were estimated using the following weighted average assumptions in the Black-Scholes option valuation method: Year Ended May 31, 2016 2015 2014 Option plan shares Expected term (in years) 4 4 4 Volatility 0.86 0.90 0.95 Expected dividend $0.00 $0.00 $0.00 Risk-free interest rates 1.21% 1.20% 1.39% Weighted-average grant date fair value $1.31 $1.52 $1.09 The fair value of our ESPP purchase rights for the fiscal 2016, 2015 and 2014 was estimated using the following weighted-average assumptions: Year End May 31, 2016 2015 2014 Employee stock purchase plan shares Expected term (in years) 0.5 2.0 0.5 2.0 0.5 2.0 Volatility 0.64 0.74 0.55 0.83 0.86 1.00 Expected dividend $ 0.00 $ 0.00 $ 0.00 Risk-free interest rates 0.40%0.76% 0.04%0.55% 0.04%0.44% Weighted-average grant date fair value $ 0.80 $ 1.43 $ 1.34 During the fiscal years ended May 31, 2016, 2015 and 2014, ESPP purchase rights of 304,000, 222,000, and 172,000 shares, respectively, were granted. Total ESPP shares issued during the fiscal years ended May 31, 2016, 2015, and 2014 were 86,000, 87,000, and 120,000 shares, respectively. As of May 31, 2016 there were 182,000 ESPP shares available for issuance. |
EARNINGS PER SHARE (“EPS”): | 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, and employee stock purchase plan shares) outstanding during the period using the treasury stock method. The following table presents the computation of basic and diluted net (loss) income per share attributable to Aehr Test Systems common shareholders (in thousands, except per share data): Year Ended May 31, 2016 2015 2014 Numerator: Net (loss) income $ (6,785 ) $ (6,647 ) $ 422 Denominator for basic net (loss) income per share: Weighted-average shares outstanding 13,091 12,047 10,877 Shares used in basic net (loss) income per share calculation 13,091 12,047 10,877 Effect of dilutive securities 1,012 Denominator for diluted net (loss) income per share 13,091 12,047 11,889 Basic net (loss) income per share $ (0.52 ) $ (0.55 ) $ 0.04 Diluted net (loss) income per share $ (0.52 ) $ (0.55 ) $ 0.04 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 Companys common stock for the period, as the effect would be anti-dilutive. In the fiscal years ended May 31, 2016 and 2015, 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 these periods are the same. Stock options to purchase 3,201,000, 3,686,000, and 301,000 shares of common stock were outstanding on May 31, 2016, 2015 and 2014, respectively, but were not included in the computation of diluted net (loss) income per share, because the inclusion of such shares would be anti-dilutive. ESPP rights to purchase 304,000, 175,000 and 131,000 ESPP shares were outstanding on May 31, 2016, 2015 and 2014, respectively, but were not included in the computation of diluted net (loss) income per share, because the inclusion of such shares would be anti-dilutive. RSUs for 35,000 shares were outstanding at May 31, 2016 but not included in the computation of diluted net (loss) income per share, because the inclusion of such shares would be anti-dilutive. The shares convertible under the Convertible Notes outstanding at May 31, 2016 were not included in the computation of diluted net (loss) income per share, because the inclusion of such shares would be anti-dilutive. |
COMPREHENSIVE (LOSS) INCOME: | COMPREHENSIVE (LOSS) INCOME: Comprehensive (loss) income generally represents all changes in shareholders equity (deficit) except those resulting from investments or contributions by shareholders. Unrealized gains and losses on foreign currency translation adjustments are included in the Companys components of comprehensive (loss) income, which are excluded from net (loss) income. Comprehensive (loss) income is included in the statements of shareholders equity (deficit) and comprehensive (loss) income. |
RECLASSIFICATION: | RECLASSIFICATION Certain reclassifications have been made to the consolidated financial statements to conform to the current period presentation. These reclassifications did not result in any change in previously reported net loss, total assets or shareholders equity (deficit). |
RECENT ACCOUNTING PRONOUNCEMENTS: | RECENT ACCOUNTING PRONOUNCEMENTS: In May 2014, as part of its ongoing efforts to assist in the convergence of US GAAP and International Financial Reporting Standards (IFRS), the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606). The new guidance 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 US GAAP. The underlying principle of the new standard is that a business or other organization will recognize revenue to reflect 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 ASU provides alternative methods of initial adoption and will become effective for us 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 (ASU 2015-14). ii) clarify the application of the principal versus agent guidance (ASU 2016-08). and iii) clarify the guidance on inconsequential and perfunctory promises and licensing (ASU 2016-10). In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606) Narrow-Scope Improvements and Practical Expedients, 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. The Company is currently evaluating the impact of adopting this new guidance on its consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Going Concern. This standard requires management to evaluate the conditions or events that raise substantial doubt about the entitys ability to continue as a going concern and whether or not it is probable that the entity will be unable to meet its obligations as they become due within one year after the date the financial statements are issued. The new standard will apply to all entities and will be effective for us in the fiscal year 2017, with early adoption permitted. The Company is currently evaluating the impact of adopting this new guidance on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, Interest Imputation of Interest. This standard requires management to simplify the presentation of debt issuance costs by presenting the costs related to obtaining a debt liability as a direct deduction from that debt liability. The debt issuance costs, or discount, is amortized over the life of the debt liability. The new standard is effective for us in fiscal 2017, with early adoption permitted. The Company has adopted this update for the fiscal year ended May 31, 2015. Refer to Note 9 of Notes to Consolidated Financial Statements, CONVERTIBLE NOTES AND LINE OF CREDIT for further discussion of the Credit Facility and Convertible Notes. In July 2015, the FASB issued ASU No. 2015-11, Inventory. This standard 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. This new standard will be effective for us in the fiscal year 2018, with early adoption permitted. The Company is currently evaluating the impact of adopting this new guidance on its consolidated financial statements. In August 2015, the FASB issued ASU No. 2015-15, Imputation of Interest. This standard clarifies ASU 2015-03, Debt Issuance Costs discussed above, in which an entity may defer and present debt issuance costs for line of credit arrangements as an asset and subsequently amortize the costs over the term of the line of credit agreement regardless of whether any amounts are outstanding. The Company is currently evaluating the impact of adopting this new guidance on its consolidated financial statements. In November 2015, FASB issued ASU No. 2015-17, Income Taxes. This standard simplifies the presentation of deferred income taxes to be classified as noncurrent in the consolidated balance sheet. This new standard will be effective for us in the fiscal year 2018, with early adoption permitted. The Company is currently evaluating the impact of adopting this new guidance on its consolidated financial statements. In February 2016, FASB issued ASU No. 2016-02, Leases. This standard 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 the 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 January 2016, FASB issued ASU No. 2016-01, 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. ASU 2016-01 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 March 2016, FASB released ASU 2016-09, Compensation - Stock Compensation. The standard 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 accounting standard will be effective for the Company beginning the first quarter of fiscal 2018, and early adoption is permitted. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements. |
