NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. BASIS OF PRESENTATION

The accompanying financial information has been prepared by Aehr Test Systems, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC. 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, 2016 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, 2016. Results for the interim periods presented herein are not necessarily indicative of results which may be reported for any other interim period or for the entire fiscal year.

PRINCIPLES OF CONSOLIDATION. The condensed consolidated financial statements include the accounts of Aehr Test Systems and its subsidiaries (collectively, the "Company," "we," "us," and "our"). All significant intercompany balances have been eliminated in consolidation. For our majority owned subsidiary, Aehr Test Systems Japan K.K., we reflected the noncontrolling interest of the portion we do not own on our Condensed Consolidated Balance Sheets in Shareholders’ Equity (Deficit) and in the Condensed Consolidated Statements of Operations.

ACCOUNTING ESTIMATES. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used to account for sales and revenue allowances, the allowance for doubtful accounts, inventory valuations, income taxes, stock-based compensation expenses, and product warranties, among others. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ materially from those estimates.

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, 2016. There have been no changes in our significant accounting policies during the nine months ended February 28, 2017.

2. 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 employee’s requisite service period. This model was developed for use in estimating the value of publicly traded options that have no vesting restrictions and are fully transferable. The Company’s employee stock options have characteristics significantly different from those of publicly traded options. For RSUs, stock-based compensation cost is based on the fair value of the Company’s common stock at the grant date. All of the Company’s stock-based compensation is accounted for as equity instruments. See Notes 10 and 11 in the Company’s Annual Report on Form 10-K for fiscal 2016 filed on August 29, 2016 for further information regarding the 2006 Equity Incentive Plan and the 2006 Employee Stock Purchase Plan.

In October 2016, the Company’s 2016 Equity Incentive Plan and the Amended and Restated Employee Stock Purchase Plan were approved by the Company’s shareholders. The 2016 Equity Incentive Plan replaces our 2006 Equity Incentive Plan, which was scheduled to expire in October 2016, and will continue in effect until 2026. A total of 2,238,467 shares of common stock have been reserved for issuance under the Company’s 2016 Equity Incentive Plan. The Amended and Restated 2006 Employee Stock Purchase Plan extends the term of the ESPP indefinitely. See the Registration Statement on Form S-8 filed on November 14, 2016 for further information regarding the 2016 Equity Incentive Plan and the ESPP.

The following table summarizes the stock-based compensation expense related to the Company’s stock-based incentive plans for the three and nine months ended February 28, 2017 and February 29, 2016 (in thousands):

	Three Months Ended		Nine Months Ended
	Feb. 28,	Feb. 29,	Feb. 28,	Feb. 29,
	2017	2016	2017	2016
Stock-based compensation in the form of employee stock options, RSUs and ESPP purchase rights, included in:
Cost of sales	$22	$20	$69	$62
Selling, general and administrative	187	145	575	569
Research and development	48	48	147	155
Total stock-based compensation	$257	$213	$791	$786

As of February 28, 2017 and February 29, 2016, there were no stock-based compensation costs capitalized as part of inventory.

During the three months ended February 28, 2017 and February 29, 2016, the Company recorded stock-based compensation related to stock options and RSUs of $232,000 and $190,000, respectively. During the nine months ended February 28, 2017 and February 29, 2016, the Company recorded stock-based compensation related to stock options and RSUs of $695,000 and $708,000, respectively.

As of February 28, 2017, the total compensation cost related to unvested stock-based awards under the Company’s 2006 and 2016 Equity Incentive Plans, but not yet recognized, was approximately $1,081,000, 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 2.4 years.

During the three months ended February 28, 2017 and February 29, 2016, the Company recorded stock-based compensation related to the ESPP of $25,000 and $23,000, respectively. During the nine months ended February 28, 2017 and February 29, 2016, the Company recorded stock-based compensation related to the ESPP of $96,000 and $78,000, respectively.

As of February 28, 2017, the total compensation cost related to purchase rights under the ESPP but not yet recognized was approximately $52,000. This cost will be amortized on a straight-line basis over a weighted average period of approximately 0.8 years.

Valuation Assumptions

Valuation and Amortization Method. The Company estimates the fair value of stock options granted using the Black-Scholes option valuation model and a single option award approach. The fair value under the single option approach is amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period.

Expected Term. The Company’s expected term represents the period that the Company’s stock-based awards are expected to be outstanding and was determined based on historical experience, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior as evidenced by changes to the terms of its stock-based awards.

Volatility. Volatility is a measure of the amounts by which a financial variable such as stock price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. The Company uses the historical volatility for the past four or five years, which matches the expected term of most of the option grants, to estimate expected volatility. Volatility for each of the ESPP’s four time periods of six months, twelve months, eighteen months, and twenty-four months is calculated separately and included in the overall stock-based compensation cost 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 February 29, 2016 and nine months ended February 28, 2017 and February 29, 2016 were estimated using the following weighted average assumptions in the Black-Scholes option valuation model:

	Three Months Ended	Nine Months Ended
	Feb. 29,	Feb. 28,	Feb. 29,
	2016	2017	2016

Expected term (in years)	4	4	4
Volatility	0.80	0.81	0.86
Risk-free interest rates	1.23%	1.02%	1.21%
Weighted average grant date fair value	$0.80	$1.09	$1.31

There were no stock options granted to employees for the three months ended February 28, 2017.

During the three and nine months ended February 28, 2017, RSUs were granted for 19,000 and 157,000 shares, respectively. The weighted average market value per share of the RSUs issued for the three and nine months ended February 28, 2017 was $2.46 and $1.78, respectively.

There were no ESPP purchase rights granted during the three and nine months ended February 28, 2017 and February 29, 2016. Total ESPP shares issued during the nine months ended February 28, 2017 and February 29, 2016 were 65,000 and 36,000 shares, respectively. As of February 28, 2017, there were 467,000 ESPP shares available for issuance.

The total intrinsic value of options exercised during the three and nine months ended February 28, 2017 was $154,000 and $564,000, respectively. The total intrinsic value of options exercised during the nine months ended February 29, 2016 was $185,000. There were no options exercised in the three months ended February 29, 2016. The weighted average remaining contractual life of the options exercisable and expected to be exercisable at February 28, 2017 was 3.85 years.

3. EARNINGS PER SHARE

Basic earnings per share is determined using the weighted average number of common shares outstanding during the period. Diluted earnings per share is determined using the weighted average number of common shares and potential common shares (representing the dilutive effect of stock options, RSUs and ESPP shares) outstanding during the period using the treasury stock method.

The following table presents the computation of basic and diluted net loss per share attributable to the Company’s common shareholders (in thousands, except per share data):

	Three Months Ended		Nine Months Ended
	Feb. 28,	Feb. 29,	Feb. 28,	Feb. 29,
	2017	2016	2017	2016

Numerator: Net loss	$(2,651)	$(2,975)	$(4,858)	$(3,729)

Denominator for basic net loss per share:
Weighted-average shares outstanding	16,672	13,164	15,411	13,058

Shares used in basic net loss per share calculation	16,672	13,164	15,411	13,058
Effect of dilutive securities	--	--	--	--

Denominator for diluted net loss per share	16,672	13,164	15,411	13,058

Basic net loss per share	$(0.16)	$(0.23)	$(0.32)	$(0.29)
Diluted net loss per share	$(0.16)	$(0.23)	$(0.32)	$(0.29)

For the purpose of computing diluted earnings per share, the weighted average number of potential common shares does not include stock options with an exercise price greater than the average fair value of the Company’s common stock for the period, as the effect would be anti-dilutive. In the three and nine months ended February 28, 2017 and February 29, 2016, potential common shares have not been included in the calculation of diluted net loss per share as the effect would be anti-dilutive. As such, the numerator and the denominator used in computing both basic and diluted net loss per share for these periods are the same. Stock options to purchase 3,157,000 shares of common stock, RSUs for 34,000 shares and ESPP rights to purchase 253,000 ESPP shares were outstanding as of February 28, 2017 but were not included in the computation of diluted net loss per share, because the inclusion of such shares would be anti-dilutive. Stock options to purchase 3,286,000 shares of common stock and ESPP rights to purchase 131,000 ESPP shares were outstanding as of February 29, 2016 but were not included in the computation of diluted net loss per share, because the inclusion of such shares would be anti-dilutive.

4. FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company’s financial instruments are measured at fair value consistent with authoritative guidance. This authoritative guidance defines fair value, establishes a framework for using fair value to measure assets and liabilities, and disclosures required related to fair value measurements.

The guidance establishes a fair value hierarchy based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels:

Level 1 - instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets.

Level 2 - instrument valuations are obtained from readily-available pricing sources for comparable instruments.

Level 3 - instrument valuations are obtained without observable market values and require a high level of judgment to determine the fair value.

The following table summarizes the Company’s financial assets measured at fair value on a recurring basis as of February 28, 2017 (in thousands):

	Balance as of
	February 28, 2017	Level 1	Level 2	Level 3
Money market funds	$804	$804	$--	$--
Certificate of deposit	50	--	50	--
Assets	$854	$804	$50	$--

The following table summarizes the Company’s 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	$--

There were no financial liabilities measured at fair value as of February 28, 2017 and May 31, 2016.

There were no transfers between Level 1 and Level 2 fair value measurements during the three and nine months ended February 28, 2017 and February 29, 2016.

The carrying amounts of financial instruments including cash, cash equivalents, receivables, accounts payable and certain other accrued liabilities, approximate fair value due to their short maturities. Based on the borrowing rates currently available to the Company for loans with similar terms, the carrying value of the debt approximates the fair value.

The Company has, at times, invested in debt and equity of private companies, and may do so again in the future, as part of its business strategy.

5. ACCOUNTS RECEIVABLE, NET

Accounts receivable represent customer trade receivables and is presented net of allowances for doubtful accounts of $24,000 at February 28, 2017 and $8,000 at May 31, 2016. 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 and nine months ended February 28, 2017 and February 29, 2016 (in thousands):

Balance at the end of the period	$86	$153	$86	$153

The accrued warranty balance is included in accrued expenses on the accompanying condensed consolidated balance sheets.

9. INCOME TAXES

Income taxes have been provided using the liability method whereby deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and net operating loss and tax credit carryforwards measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse or the carryforwards are utilized. Valuation allowances are established when it is determined that it is more likely than not that such assets will not be realized.

Since fiscal 2009, a full valuation allowance was established against all deferred tax assets as management determined that it is more likely than not that certain deferred tax assets will not be realized.

The Company accounts for uncertain tax positions consistent with authoritative guidance. The guidance prescribes a “more likely than not” recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company does not expect any material change in its unrecognized tax benefits over the next twelve months. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income taxes.

Although the Company files U.S. federal, various state, and foreign tax returns, the Company’s only major tax jurisdictions are the United States, California, Germany and Japan. Tax years 1997 - 2016 remain subject to examination by the appropriate governmental agencies due to tax loss carryovers from those years.

11. LONG-TERM DEBT

On April 10, 2015, the Company entered into a Convertible Note Purchase and Credit Facility Agreement (the “Purchase Agreement”) with QVT Fund LP and Quintessence Fund L.P. (the “Purchasers”) providing for (a) the Company’s sale to the Purchasers of $4,110,000 in aggregate principal amount of 9.0% Convertible Secured Notes due 2017 (the “Convertible Notes”) and (b) a secured revolving loan facility (the “Credit Facility”) in an aggregate principal amount of up to $2,000,000. On August 22, 2016 the Purchase Agreement was amended to extend the maturity date of the Convertible Notes to April 10, 2019, decrease the conversion price from $2.65 per share to $2.30 per share, decrease the forced conversion price from $7.50 per share to $6.51 per share, and allow for additional equity awards.

The Convertible Notes bear interest at an annual rate of 9.0% and will mature on April 10, 2019 unless repurchased or converted prior to that date. Interest is payable quarterly on March 1, June 1, September 1 and December 1 of each year. Debt issuance costs of $356,000, which are being accreted over the term of the original loan using the effective interest rate method, were offset against the loan balance. During the three and nine months ended February 28, 2017, $44,000 and $133,000, respectively, of amortization costs were recognized as interest expense. Unamortized debt issuance costs of $15,000 were offset against the loan balance at February 28, 2017.

The conversion price for the Convertible Notes is $2.30 per share and is subject to adjustment upon the occurrence of certain specified events. Holders may convert all or any part of the principal amount of their Convertible Notes in integrals of $10,000 at any time prior to the maturity date. Upon conversion, the Company will deliver shares of its common stock to the holder of Convertible Notes electing such conversion. The Company may not redeem the Convertible Notes prior to maturity.

On April 14, 2016, $900,000 drawn against the Credit Facility was converted to Convertible Notes. On July 17, 2016, $1,100,000 drawn against the Credit Facility was converted to Convertible Notes. At February 28, 2017 there was no remaining balance available on the Credit Facility.

The Company’s obligations under the Purchase Agreement are secured by substantially all of the assets of the Company.

Long-term debt, net of debt issuance costs (in thousands):

	February 28,	May 31,
	2017	2016
Principal	$6,110	$6,110
Unamortized debt issuance costs	(15)	(148)
	$6,095	$5,962

12. EQUITY

On August 8, 2016 the Company issued 200,000 shares of its common stock to Semics Inc., a semiconductor test equipment provider that produces fully automatic wafer probe systems, in consideration for cancellation of an outstanding invoice of $323,000 for capital equipment.

On September 28, 2016, the Company sold 2,721,540 shares of its common stock in a private placement transaction to certain institutional and accredited investors. The purchase price per share of the common stock sold in the private placement was $2.15, resulting in gross proceeds to the Company of $5,851,000, before offering expenses. The net proceeds after offering expenses were $5,299,000.

13. RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, as part of its ongoing efforts to assist in the convergence of GAAP and International Financial Reporting Standards (“IFRS”), the Financial Accounting Standards Board (“FASB”) issued an accounting standards update related to revenue from contracts with customers. This standard sets forth a new five-step revenue recognition model which replaces the prior revenue recognition guidance in its entirety and is intended to eliminate numerous industry-specific pieces of revenue recognition guidance that have historically existed in GAAP. The underlying principle of the new standard is that a business or other organization will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. The standard also requires more detailed disclosures and provides additional guidance for transactions that were not addressed completely in the prior accounting guidance. The standard provides alternative methods of initial adoption and will become effective for the Company beginning in the first quarter of fiscal 2019. The FASB has issued several updates to the standard which i) defer the original effective date from January 1, 2017 to January 1, 2018, while allowing for early adoption as of January 1, 2017. ii) clarify the application of the principal versus agent guidance. and iii) clarify the guidance on inconsequential and perfunctory promises and licensing. In May 2016, the FASB issued an update to address certain narrow aspects of the guidance including collectibility criterion, collection of sales taxes from customers, noncash consideration, contract modifications and completed contracts. This issuance does not change the core principle of the guidance in the initial topic issued in May 2014. In December 2016, the FASB issued updated guidance regarding revenue from contracts with customers. Some topics that could impact the Company include corrections and improvements around the following: contract costs impairment testing, disclosure of remaining performance obligations and prior period obligations, contract modifications, and contract asset versus receivable. The Company is currently evaluating the impact of adopting this new guidance on its consolidated financial statements.

In August 2014, the FASB issued authoritative guidance related to going concern. This guidance requires management to evaluate the conditions or events that raise substantial doubt about the entity’s 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. This guidance will apply to all entities and will be effective for us in 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 July 2015, the FASB issued an accounting standards update that requires management to measure inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This new standard will be effective for us in 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 November 2015, the FASB issued an accounting standards update related to deferred tax assets and liabilities. This standard simplifies the presentation of deferred income taxes to be classified as noncurrent in the consolidated balance sheet. This new standard will be effective for us in 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 January 2016, the FASB issued an accounting standards update related to recognition and measurement of financial assets and financial liabilities. This standard changes accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. In addition, it clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. This standard is effective for us in fiscal year 2020. Early adoption is permitted. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements.

In February 2016, the FASB issued authoritative guidance related to leases. This guidance requires management to present all leases greater than one year on the balance sheet as a liability to make payments and an asset as the right to use the underlying asset for the lease term. This new standard will be effective for us in fiscal year 2020, with early adoption permitted. The Company is currently evaluating the impact of adopting this new guidance on its consolidated financial statements.

In March 2016, the FASB released an accounting standards update that simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, forfeitures, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The 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.

In June 2016, the FASB issued an accounting standard update that requires measurement and recognition of expected credit losses for financial assets held based on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2021 on a modified retrospective basis, and early adoption in fiscal 2020 is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.

In August 2016, the FASB issued authoritative guidance related to the classification of certain cash receipts and cash payments on the statement of cash flows. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2019 on a retrospective basis, and early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated statements of cash flows.

In October 2016, the FASB issued an accounting standard update that requires recognition of the income tax consequences of intra-entity transfers of assets (other than inventory) at the transaction date. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2019 on a modified retrospective basis, and early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.

In November 2016, the FASB issued authoritative guidance related to statements of cash flows. This guidance clarifies that amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of period total amounts shown on the statement of cash flows. The accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2019 on a retrospective basis, and early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.

In December 2016, the FASB issued authoritative guidance related to technical corrections and improvements. This guidance provides minor updates on a variety of codification topics and are not expected to have a significant effect on current accounting practice. Most of these corrections do not have a transition date as they are minor in nature.

OVERVIEW

The Company was founded in 1977 to develop and manufacture burn-in and test equipment for the semiconductor industry. Since its inception, the Company has sold more than 2,500 systems to semiconductor manufacturers, semiconductor contract assemblers and burn-in and test service companies worldwide. The Company’s principal products currently are the Advanced Burn-in and Test System, or ABTS, the FOX full wafer contact parallel test and burn-in system, the MAX burn-in system, WaferPak contactors, the DiePak carrier and test fixtures.

The Company’s net sales consist primarily of sales of systems, WaferPak contactors, test fixtures, die carriers, upgrades and spare parts, revenues from service contracts, and engineering development charges. The Company's selling arrangements may include contractual customer acceptance provisions, which are mostly deemed perfunctory or inconsequential, and installation of the product occurs after shipment and transfer of title.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The Company’s discussion and analysis of its financial condition and results of operations are based upon the Company’s condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these condensed consolidated financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to customer programs and incentives, product returns, bad debts, inventories, income taxes, financing operations, warranty obligations, and long-term service contracts. The Company’s estimates are derived from historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Those results form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. For a discussion of the critical accounting policies, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates” in the Company’s Annual Report on Form 10-K for the fiscal year ended May 31, 2016.

There have been no material changes to our critical accounting policies and estimates during the nine months ended February 28, 2017 compared to those discussed in our Annual Report on Form 10-K for the fiscal year ended May 31, 2016.

THREE MONTHS ENDED FEBRUARY 28, 2017 COMPARED TO THREE MONTHS ENDED FEBRUARY 29, 2016

NET SALES. Net sales increased to $2.7 million for the three months ended February 28, 2017 from $1.7 million for the three months ended February 29, 2016, an increase of 59.9%. The increase in net sales for the three months ended February 28, 2017 resulted primarily from an increase in net sales of the Company’s Test During Burn-in (TDBI) products, partially offset by a decrease in net sales of the Company’s wafer-level products. Net sales of the Company’s TDBI products for the three months ended February 28, 2017 were $2.5 million, and increased approximately $1.7 million from the three months ended February 29, 2016. Net sales of the Company’s wafer-level products for the three months ended February 28, 2017 were $0.1 million, and decreased approximately $0.8 million from the three months ended February 29, 2016.

GROSS PROFIT. Gross profit consists of net sales less cost of sales. Cost of sales consists primarily of the cost of materials, assembly and test costs, and overhead from operations. Gross profit increased to $0.5 million for the three months ended February 28, 2017 from $0.2 million for the three months ended February 29, 2016, an increase of 197.6%. Gross profit margin increased to 18.8% for the three months ended February 28, 2017 from 10.1% for the three months ended February 29, 2016. The lower gross profit margin for the three months ended February 29, 2016 was primarily due to a higher level of inventory reserves recorded and was also impacted by higher unabsorbed overhead charged to cost of goods due to lower manufacturing and revenue levels in the quarter.

SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and administrative, or SG&A, expenses consist primarily of salaries and related costs of employees, commission expenses to independent sales representatives, product promotion and other professional services. SG&A expenses were flat at $1.7 million for the three months ended February 28, 2017 compared with the three months ended February 29, 2016.

RESEARCH AND DEVELOPMENT. Research and development, or R&D, expenses consist primarily of salaries and related costs of employees engaged in ongoing research, design and development activities, costs of engineering materials and supplies, and professional consulting expenses. R&D expenses decreased to $1.2 million for the three months ended February 28, 2017 from $1.3 million for the three months ended February 29, 2016, a decrease of 3.5%. The decrease in R&D expenses was primarily due to a decrease in project expenses.

INTEREST EXPENSE. Interest expenses were $178,000 and $165,000 for the three months ended February 28, 2017 and February 29, 2016, respectively. The increase in interest expense in the three months ended February 28, 2017 was primarily due to higher average borrowings.

OTHER (EXPENSE) INCOME, NET. Other expense, net was $2,000 and $24,000 for the three months ended February 28, 2017 and February 29, 2016, respectively. The change in other expense was due primarily to losses realized in connection with the fluctuation in the value of the dollar compared to foreign currencies during the referenced periods.

INCOME TAX (EXPENSE) BENEFIT. Income tax expense was $2,000 for the three months ended February 28, 2017 compared with income tax benefit of $33,000 for the three months ended February 29, 2016. The income tax benefit in the three months ended February 29, 2016 was due to a reversal of tax liabilities previously established for uncertain tax positions, which were no longer required.

NINE MONTHS ENDED FEBRUARY 28, 2017 COMPARED TO NINE MONTHS ENDED FEBRUARY 29, 2016

NET SALES. Net sales decreased to $12.2 million for the nine months ended February 28, 2017 from $12.9 million for the nine months ended February 29, 2016, a decrease of 5.5%. The decrease in net sales for the nine months ended February 28, 2017 resulted primarily from a decrease in net sales of the Company’s wafer-level products, partially offset by an increase in net sales of the Company’s TDBI products. Net sales of the Company’s wafer-level products for the nine months ended February 28, 2017 were $4.3 million, and decreased approximately $3.9 million from the nine months ended February 29, 2016. Net sales of the Company’s TDBI products for the nine months ended February 28, 2017 were $7.8 million, and increased approximately $3.1 million from the nine months ended February 29, 2016.

GROSS PROFIT. Gross profit decreased to $4.2 million for the nine months ended February 28, 2017 from $5.2 million for the nine months ended February 29, 2016, a decrease of 20.4%. Gross profit margin decreased to 34.2% for the nine months ended February 28, 2017 from 40.5% for the nine months ended February 29, 2016. The higher gross profit margin for the nine months ended February 29, 2016 was primarily the result of the sale of systems which included previously written-down material.

SELLING, GENERAL AND ADMINISTRATIVE. SG&A expenses decreased to $5.1 million for the nine months ended February 28, 2017 from $5.3 million for the nine months ended February 29, 2016, a decrease of 2.0%. The decrease in SG&A expenses was primarily due to the decrease in sales commissions to outside sales representatives.

RESEARCH AND DEVELOPMENT. R&D expenses were flat at $3.3 million for the nine months ended February 28, 2017 compared with the nine months ended February 29, 2016.

INTEREST EXPENSE. Interest expense was $537,000 for the nine months ended February 28, 2017 compared with $437,000 for the nine months ended February 29, 2016. The increase in interest expense in the nine months ended February 28, 2017 was primarily due to higher average borrowings.

OTHER (EXPENSE) INCOME, NET. Other income, net was $38,000 and $7,000 for the nine months ended February 28, 2017 and February 29, 2016, respectively. The change in other income was due primarily to gains realized in connection with the fluctuation in the value of the dollar compared to foreign currencies during the referenced periods.

INCOME TAX (EXPENSE) BENEFIT. Income tax expenses were $36,000 and $11,000 for the nine months ended February 28, 2017 and February 29, 2016, respectively.

LIQUIDITY AND CAPITAL RESOURCES

Net cash used in operating activities was $4.5 million and $4.7 million for the nine months ended February 28, 2017 and February 29, 2016, respectively. For the nine months ended February 28, 2017, net cash used in operating activities was primarily the result of net loss of $4.9 million, as adjusted to exclude the effect of non-cash charge of stock-based compensation expense of $0.8 million. Net cash used in operations was also impacted by an increase in accounts receivable of $1.1 million, partially offset by an increase in accounts payable of $0.7 million. The increase in accounts receivable was primarily due to large shipments toward the end of February 28, 2017. The increase in accounts payable was primarily due to inventory purchases to support future shipments. For the nine months ended February 29, 2016, net cash used in operating activities was primarily the result of net loss of $3.7 million, as adjusted to exclude the effect of non-cash charge of stock-based compensation expense of $0.8 million, as well as a decrease in customer deposits and deferred revenue of $2.6 million and an increase in accounts payable of $1.1 million. The decrease in customer deposits and deferred revenue was primarily due to the shipments of customer orders with down payments. The increase in accounts payable was primarily due to higher expenditures associated with higher revenue.

Net cash used in investing activities was $219,000 and $890,000 for the nine months ended February 28, 2017 and February 29, 2016, respectively. Net cash used in investing activities for the nine months ended February 28, 2017 was due to the purchases of property and equipment. Net cash used in investing activities for the nine months ended February 29, 2016 was due to the purchases of property and equipment for our capital and infrastructure improvement plan to showcase our products and to enhance our manufacturing capabilities in preparation for increased demand.

Financing activities provided cash of $5.8 million and $2.5 million for the nine months ended February 28, 2017 and February 29, 2016, respectively. Net cash provided by financing activities during the nine months ended February 28, 2017 was due primarily to the net proceeds of $5.3 million from the sale of our common stock in a private placement transaction to certain institutional and accredited investors that closed on September 28, 2016 and $0.5 million in proceeds from the issuance of common stock under employee plans. Net cash provided by financing activities during the nine months ended February 29, 2016 was due to $2.0 million borrowing from line of credit and $0.5 million in proceeds from the issuance of common stock under employee plans.

The effect of fluctuation in exchange rates used cash of $22,000 for the nine months ended February 28, 2017 and provided cash of $82,000 for the nine months ended February 29, 2016. The change between cash used and cash provided was due to the fluctuation in the value of the dollar compared to foreign currencies.

As of February 28, 2017 and May 31, 2016, the Company had working capital of $6.5 million and $4.1 million, respectively. Working capital consists of cash and cash equivalents, accounts receivable, inventory and other current assets, less current liabilities.

The Company leases its manufacturing and office space under operating leases. The Company entered into a non-cancelable operating lease agreement for its United States manufacturing and office facilities, which was renewed in November 2014 and expires in June 2018. Under the lease agreement, the Company is responsible for payments of utilities, taxes and insurance.

From time to time, the Company evaluates potential acquisitions of businesses, products or technologies that complement the Company’s business. If consummated, any such transactions may use a portion of the Company’s working capital or require the issuance of equity. The Company has no present understandings, commitments or agreements with respect to any material acquisitions.

The Company anticipates that its 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. On August 22, 2016, the Company extended the maturity date of the Convertible Notes due in 2017 to April 10, 2019 which improves its ability to meet current liabilities for fiscal 2017. On September 28, 2016, the Company sold 2,721,540 shares of its common stock in a private placement transaction resulting in net proceeds after offering expenses of $5,299,000 to the Company. Refer to Note 12, “EQUITY”. Depending on the Company’s 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.

OFF-BALANCE SHEET ARRANGEMENTS

The Company has not entered into any off-balance sheet financing arrangements and has not established any variable interest entities.

OVERVIEW OF CONTRACTUAL OBLIGATIONS

On April 10, 2015, the Company entered into a Convertible Note Purchase and Credit Facility Agreement providing for the Company’s sale of the Convertible Notes and a secured revolving loan facility. On August 22, 2016, the Company entered into an amendment to the Convertible Note Purchase and Credit Facility Agreement and the Convertible Notes to extend the maturity date of the Convertible Notes to April 10, 2019. See Note 11, “LONG-TERM DEBT”, for a description of the Convertible Note Purchase and Credit Facility Agreement and the Convertible Notes.

There have been no additional material changes in the composition, magnitude or other key characteristics of the Company's contractual obligations or other commitments as disclosed in the Company's Annual Report on Form 10-K for the year ended May 31, 2016.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

The Company had no holdings of derivative financial or commodity instruments as of February 28, 2017 or May 31, 2016.

The Company is exposed to financial market risks, including changes in interest rates and foreign currency exchange rates. The Company only invests its short-term excess cash in government-backed securities with maturities of 18 months or less. The Company does not use any financial instruments for speculative or trading purposes. Fluctuations in interest rates would not have a material effect on the Company’s financial position, results of operations or cash flows.

A majority of the Company’s revenue and capital spending is transacted in U.S. Dollars. The Company, however, enters into transactions in other currencies, primarily Euros and Japanese Yen. Since the price is determined at the time a purchase order is accepted, the Company is exposed to the risks of fluctuations in the foreign currency-U.S. Dollar exchange rates during the lengthy period from purchase order to ultimate payment. This exchange rate risk is partially offset to the extent that the Company’s subsidiaries incur expenses payable in their local currency. To date, the Company has not invested in instruments designed to hedge currency risks. In addition, the Company’s subsidiaries typically carry debt or other obligations due to the Company that may be denominated in either their local currency or U.S. Dollars. Since the Company’s subsidiaries’ financial statements are based in their local currency and the Company’s condensed consolidated financial statements are based in U.S. Dollars, the Company’s subsidiaries and the Company recognize foreign exchange gains or losses in any period in which the value of the local currency rises or falls in relation to the U.S. Dollar. A 10% decrease in the value of the subsidiaries’ local currency as compared with the U.S. Dollar would not be expected to result in a significant change to the Company’s net income or loss. There have been no material changes in our risk exposure since the end of the last fiscal year, nor are any material changes to our risk exposure anticipated.

Item 4. CONTROLS AND PROCEDURES

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

CHANGES IN INTERNAL CONTROLS OVER FINANCIAL REPORTING. There was no change in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, that occurred during the period covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

INHERENT LIMITATIONS OF INTERNAL CONTROLS. Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within us have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving our stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II - OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

None.

Item 1A. RISK FACTORS

You should carefully consider the risks described below. These risks are not the only risks that we may face. Additional risks and uncertainties that we are unaware of, or that we currently deem immaterial, also may become important factors that affect us. If any of the following risks occur, our business, financial condition or results of operations could be materially and adversely affected which could cause our actual operating results to differ materially from those indicated or suggested by forward-looking statements made in this Quarterly Report on Form 10-Q and in other documents we filed with the U.S. Securities and Exchange Commission, including without limitation our most recently filed Annual Report on Form 10-K or presented elsewhere by management from time to time.

We generate a large portion of our sales from a small number of customers. If we were to lose one or more of our large customers, operating results could suffer dramatically.

The semiconductor manufacturing industry is highly concentrated, with a relatively small number of large semiconductor manufacturers and contract assemblers accounting for a substantial portion of the purchases of semiconductor equipment. Sales to the Company’s five largest customers accounted for approximately 94%, 79%, and 90% of its net sales in fiscal 2016, 2015 and 2014, respectively. During fiscal 2016, Apple and Texas Instruments accounted for approximately 47% and 32%, respectively, of the Company’s net sales. During fiscal 2015, Texas Instruments and Micronas accounted for approximately 45% and 11%, respectively, of the Company’s net sales. During fiscal 2014, Texas Instruments, Spansion and Micronas accounted for approximately 40%, 30% and 12%, respectively, of the Company’s net sales. No other customers accounted for more than 10% of the Company’s net sales for any of these periods.

We expect that sales of our products to a limited number of customers will continue to account for a high percentage of net sales for the foreseeable future. In addition, sales to particular customers may fluctuate significantly from quarter to quarter. The loss of, reduction or delay in an order, or orders from a significant customer, or a delay in collecting or failure to collect accounts receivable from a significant customer could adversely affect our business, financial condition and operating results.

If we are not able to reduce our operating expenses sufficiently during periods of weak revenue, or if we utilize significant amounts of cash to support operating losses, we may erode our cash resources and may not have sufficient cash to operate our business.

In recent years, in the face of a downturn in our business and a decline in our net sales, we implemented a variety of cost controls and restructured our operations with the goal of reducing our operating costs to position ourselves to more effectively meet the needs of the then weak market for test and burn-in equipment. While we took significant steps to minimize our expense levels and to increase the likelihood that we would have sufficient cash to support operations during the downturn, from fiscal 2009 through fiscal 2016, with the exception of fiscal 2014, we experienced operating losses. 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 11 of Notes to Condensed Consolidated Financial Statements, “LONG-TERM DEBT” for further discussion of the Convertible Notes. Depending on our rate of growth and profitability, and our ability to obtain significant orders with down payments, we may require additional equity or debt financing to meet our 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.

Our common stock may be delisted from The NASDAQ Capital Market if we cannot maintain compliance with NASDAQ’s continued listing requirements.

In order to maintain our listing on The NASDAQ Capital Market, we are required to maintain compliance with NASDAQ’s continued listing requirements. The continued listing requirements include, among others, a minimum bid price of $1.00 per share and any of: (i) a minimum stockholders’ equity of $2.5 million; (ii) a market value of listed securities of at least $35 million; or (iii) net income from continuing operations of $500,000 in the most recently completed fiscal year or in two of the last three fiscal years. There are no assurances that we will be able to sustain long-term compliance with NASDAQ’s continued listing requirements. On April 19, 2016 the Company was notified by NASDAQ that it was no longer in compliance with NASDAQ’s continued listing requirements as we did not have a minimum stockholders’ equity of $2.5 million. On October 3, 2016, the Company was notified by NASDAQ that the Company had regained compliance with NASDAQ’s continued listing requirements. If we fail to maintain compliance with the applicable NASDAQ continued listing requirements, our stock may be delisted.

If we are delisted, we would expect our common stock to be traded in the over-the-counter market, which could make trading our common stock more difficult for investors, potentially leading to declines in our share price and liquidity. Delisting from The NASDAQ Capital Market would also constitute an event of default under our Convertible Notes. In addition, delisting could result in negative publicity and make it more difficult for us to raise additional capital.

We rely on increasing market acceptance for our FOX system, and we may not be successful in attracting new customers or maintaining our existing customers.

A principal element of our business strategy is to increase our presence in the test equipment market through system sales in our FOX wafer-level test and burn-in product family. The market for the FOX systems is in the early stages of development. Market acceptance of the FOX system is subject to a number of risks. Before a customer will incorporate the FOX system into a production line, lengthy qualification and correlation tests must be performed. We anticipate that potential customers may be reluctant to change their procedures in order to transfer burn-in and test functions to the FOX system. Initial purchases are expected to be limited to systems used for these qualifications and for engineering studies. Market acceptance of the FOX system also may be affected by a reluctance of IC manufacturers to rely on relatively small suppliers such as us. As is common with new complex products incorporating leading-edge technologies, we may encounter reliability, design and manufacturing issues as we begin volume production and initial installations of FOX systems at customer sites. The failure of the FOX system to achieve increased market acceptance would have a material adverse effect on our future operating results, long-term prospects and our stock price.

The semiconductor equipment industry is intensely competitive. In each of the markets it serves, the Company faces competition from established competitors and potential new entrants, many of which have greater financial, engineering, manufacturing and marketing resources than the Company.

The Company’s FOX full wafer contact systems face competition from larger systems manufacturers that have significant technological know-how and manufacturing capability. The Company’s ABTS Test During Burn-in (TDBI) systems have faced and are expected to continue to face increasingly severe competition, especially from several regional, low-cost manufacturers and from systems manufacturers that offer higher power dissipation per device under test. Some users of such systems, such as independent test labs, build their own burn-in systems, while others, particularly large IC manufacturers in Asia, acquire burn-in systems from captive or affiliated suppliers. The Company’s WaferPak products are facing and are expected to face increasing competition. Several companies have developed or are developing full-wafer and single-touchdown probe cards.

The Company expects its competitors to continue to improve the performance of their current products and to introduce new products with improved price and performance characteristics. New product introductions by the Company’s competitors or by new market entrants could cause a decline in sales or loss of market acceptance of the Company’s products. The Company has observed price competition in the systems market, particularly with respect to its less advanced products. Increased competitive pressure could also lead to intensified price-based competition, resulting in lower prices which could adversely affect the Company’s operating margins and results. The Company believes that to remain competitive it must invest significant financial resources in new product development and expand its customer service and support worldwide. There can be no assurance that the Company will be able to compete successfully in the future.

We rely on continued market acceptance of our ABTS system and our ability to complete certain enhancements.

Continued market acceptance of the ABTS family, first introduced in fiscal 2008, is subject to a number of risks. It is important that we achieve customer acceptance, customer satisfaction and increased market acceptance as we add new features and enhancements to the ABTS product. To date, the Company has shipped ABTS systems to customers worldwide for use in both reliability and production applications. The Company has recognized a weakening of ABTS product sales last fiscal year. The failure of the ABTS family to increase revenues above current levels would have a material adverse effect on our future operating results.

A substantial portion of our net sales is generated by relatively small volume, high value transactions.

We derive a substantial portion of our net sales from the sale of a relatively small number of systems which typically range in purchase price from approximately $300,000 to well over $1 million per system. As a result, the loss or deferral of a limited number of system sales could have a material adverse effect on our net sales and operating results in a particular period. Most customer purchase orders are subject to cancellation or rescheduling by the customer with limited penalties, and, therefore, backlog at any particular date is not necessarily indicative of actual sales for any succeeding period. From time to time, cancellations and rescheduling of customer orders have occurred, and delays by our suppliers in providing components or subassemblies to us have caused delays in our shipments of our own products. There can be no assurance that we will not be materially adversely affected by future cancellations or rescheduling. For non-standard products where we have not effectively demonstrated the ability to meet specifications in the customer environment, we defer revenue until we have met such customer specifications. Any delay in meeting customer specifications could have a material adverse effect on our operating results. A substantial portion of net sales typically are realized near the end of each quarter. A delay or reduction in shipments near the end of a particular quarter, due, for example, to unanticipated shipment rescheduling, cancellations or deferrals by customers, customer credit issues, unexpected manufacturing difficulties experienced by us or delays in deliveries by suppliers, could cause net sales in a particular quarter to fall significantly below our expectations.

We may experience increased costs associated with new product introductions.

As is common with new complex products incorporating leading-edge technologies, we have encountered reliability, design and manufacturing issues as we began volume production and initial installations of certain products at customer sites. Some of these issues in the past have been related to components and subsystems supplied to us by third parties who have in some cases limited the ability of us to address such issues promptly. This process in the past required and in the future is likely to require us to incur un-reimbursed engineering expenses and to experience larger than anticipated warranty claims which could result in product returns. In the early stages of product development there can be no assurance that we will discover any reliability, design and manufacturing issues or, that if such issues arise, that they can be resolved to the customers’ satisfaction or that the resolution of such problems will not cause us to incur significant development costs or warranty expenses or to lose significant sales opportunities.

Periodic economic and semiconductor industry downturns could negatively affect our business, results of operations and financial condition.

Periodic global economic and semiconductor industry downturns have negatively affected and could continue to negatively affect our business, results of operations, and financial condition. Financial turmoil in the banking system and financial markets has resulted, and may result in the future, in a tightening of the credit markets, disruption in the financial markets and global economy downturn. These events may contribute to significant slowdowns in the industry in which we operate. Difficulties in obtaining capital and deteriorating market conditions can pose the risk that some of our customers may not be able to obtain necessary financing on reasonable terms, which could result in lower sales. Customers with liquidity issues may lead to additional bad debt expense.

Turmoil in the international financial markets has resulted, and may result in the future, in dramatic currency devaluations, stock market declines, restriction of available credit and general financial weakness. In addition, flash memory and other device prices have historically declined, and will likely do so again in the future. These developments may affect us in several ways. The market for semiconductors and semiconductor capital equipment has historically been cyclical, and we expect this to continue in the future. The uncertainty of the semiconductor market may cause some manufacturers in the future to further delay capital spending plans. Economic conditions may also affect the ability of our customers to meet their payment obligations, resulting in cancellations or deferrals of existing orders and limiting additional orders. In addition, some governments have subsidized portions of fabrication facility construction, and financial turmoil may reduce these governments’ willingness to continue such subsidies. Such developments could have a material adverse effect on our business, financial condition and results of operations.

The recent economic conditions and uncertainty about future economic conditions make it challenging for us to forecast our operating results, make business decisions, and identify the risks that may affect our business, financial condition and results of operations. If such conditions recur, and we are not able to timely and appropriately adapt to changes resulting from the difficult macroeconomic environment, our business, financial condition or results of operations may be materially and adversely affected.

We sell our products and services worldwide, and our business is subject to risks inherent in conducting business activities in geographic regions outside of the United States.

Approximately 80%, 64%, and 56% of our net sales for fiscal 2016, 2015 and 2014, respectively, were attributable to sales to customers for delivery outside of the United States. We operate a sales, service and limited manufacturing organization in Germany and sales and service organizations in Japan and Taiwan. We expect that sales of products for delivery outside of the United States will continue to represent a substantial portion of our future net sales. Our future performance will depend, in significant part, upon our ability to continue to compete in foreign markets which in turn will depend, in part, upon a continuation of current trade relations between the United States and foreign countries in which semiconductor manufacturers or assemblers have operations. A change toward more protectionist trade legislation in either the United States or such foreign countries, such as a change in the current tariff structures, export compliance or other trade policies, could adversely affect our ability to sell our products in foreign markets. In addition, we are subject to other risks associated with doing business internationally, including longer receivable collection periods and greater difficulty in accounts receivable collection, the burden of complying with a variety of foreign laws, difficulty in staffing and managing global operations, risks of civil disturbance or other events which may limit or disrupt markets, international exchange restrictions, changing political conditions and monetary policies of foreign governments.

Approximately 97%, 2% and 1% of our net sales for fiscal 2016 were denominated in U.S. Dollars, Euros and Japanese Yen, respectively. Although the percentages of net sales denominated in Euros and Japanese Yen were small in fiscal 2016, they have been larger in the past and could become significant again in the future. A large percentage of net sales to European customers are denominated in U.S. Dollars, but sales to many Japanese customers are denominated in Japanese Yen. Because a substantial portion of our net sales is from sales of products for delivery outside the United States, an increase in the value of the U.S. Dollar relative to foreign currencies would increase the cost of our products compared to products sold by local companies in such markets. In addition, since the price is determined at the time a purchase order is accepted, we are exposed to the risks of fluctuations in the U.S. Dollar exchange rate during the lengthy period from the date a purchase order is received until payment is made. This exchange rate risk is partially offset to the extent our foreign operations incur expenses in the local currency. To date, we have not invested in any instruments designed to hedge currency risks. Our operating results could be adversely affected by fluctuations in the value of the U.S. Dollar relative to other currencies.

Our industry is subject to rapid technological change and our ability to remain competitive depends on our ability to introduce new products in a timely manner.

The semiconductor equipment industry is subject to rapid technological change and new product introductions and enhancements. Our ability to remain competitive depends in part upon our ability to develop new products and to introduce them at competitive prices and on a timely and cost-effective basis. Our success in developing new and enhanced products depends upon a variety of factors, including product selection, timely and efficient completion of product design, timely and efficient implementation of manufacturing and assembly processes, product performance in the field and effective sales and marketing. Because new product development commitments must be made well in advance of sales, new product decisions must anticipate both future demand and the technology that will be available to supply that demand. Furthermore, introductions of new and complex products typically involve a period in which design, engineering and reliability issues are identified and addressed by our suppliers and by us. There can be no assurance that we will be successful in selecting, developing, manufacturing and marketing new products that satisfy market demand. Any such failure would materially and adversely affect our business, financial condition and results of operations.

Because of the complexity of our products, significant delays can occur between a product’s introduction and the commencement of the volume production of such product. We have experienced, from time to time, significant delays in the introduction of, and technical and manufacturing difficulties with, certain of our products and may experience delays and technical and manufacturing difficulties in future introductions or volume production of our new products. Our inability to complete new product development, or to manufacture and ship products in time to meet customer requirements would materially adversely affect our business, financial condition and results of operations.

Our dependence on subcontractors and sole source suppliers may prevent us from delivering our products on a timely basis and expose us to intellectual property infringement.

We rely on subcontractors to manufacture many of the components or subassemblies used in our products. Our FOX and ABTS systems and WaferPak contactors contain several components, including environmental chambers, power supplies, high-density interconnects, wafer contactors, signal distribution substrates, WaferPak Aligners and certain ICs that are currently supplied by only one or a limited number of suppliers. Our reliance on subcontractors and single source suppliers involves a number of significant risks, including the loss of control over the manufacturing process, the potential absence of adequate capacity and reduced control over delivery schedules, manufacturing yields, quality and costs. In the event that any significant subcontractor or single source supplier is unable or unwilling to continue to manufacture subassemblies, components or parts in required volumes, we would have to identify and qualify acceptable replacements. The process of qualifying subcontractors and suppliers could be lengthy, and no assurance can be given that any additional sources would be available to us on a timely basis. Any delay, interruption or termination of a supplier relationship could adversely affect our ability to deliver products, which would harm our operating results.

Our suppliers manufacture components, tooling, and provide engineering services. During this process, our suppliers are allowed access to our intellectual property. While we maintains patents to protect from intellectual property infringement, there can be no assurance that technological information gained in the manufacture of our products will not be used to develop a new product, improve processes or techniques which compete against our products. Litigation may be necessary to enforce or determine the validity and scope of our proprietary rights, and there can be no assurance that our intellectual property rights, if challenged, will be upheld as valid.

Future changes in semiconductor technologies may make our products obsolete.

Future improvements in semiconductor design and manufacturing technology may reduce or eliminate the need for our products. For example, improvements in semiconductor process technology and improvements in conventional test systems, such as reduced cost or increased throughput, may significantly reduce or eliminate the market for one or more of our products. If we are not able to improve our products or develop new products or technologies quickly enough to maintain a competitive position in our markets, our business may decline.

Our stock price may fluctuate.

The price of our common stock has fluctuated in the past and may fluctuate significantly in the future. We believe that factors such as announcements of developments related to our business, fluctuations in our operating results, general conditions in the semiconductor and semiconductor equipment industries as well as the worldwide economy, announcement of technological innovations, new systems or product enhancements by us or our competitors, fluctuations in the level of cooperative development funding, acquisitions, changes in governmental regulations, developments in patents or other intellectual property rights and changes in our relationships with customers and suppliers could cause the price of our common stock to fluctuate substantially. In addition, in recent years the stock market in general, and the market for small capitalization and high technology stocks in particular, have experienced extreme price fluctuations which have often been unrelated to the operating performance of the affected companies. Such fluctuations could adversely affect the market price of our common stock.

We depend on our key personnel and our success depends on our ability to attract and retain talented employees.

Our success depends to a significant extent upon the continued service of Gayn Erickson, our President and Chief Executive Officer, as well as other executive officers and key employees. We do not maintain key person life insurance for our benefit on any of our personnel, and none of our employees are subject to a non-competition agreement with us. The loss of the services of any of our executive officers or a group of key employees could have a material adverse effect on our business, financial condition and operating results. Our future success will depend in significant part upon our ability to attract and retain highly skilled technical, management, sales and marketing personnel. There is a limited number of personnel with the requisite skills to serve in these positions, and it has become increasingly difficult for us to hire such personnel. Competition for such personnel in the semiconductor equipment industry is intense, and there can be no assurance that we will be successful in attracting or retaining such personnel. Changes in management could disrupt our operations and adversely affect our operating results.

We may be subject to litigation relating to intellectual property infringement which would be time-consuming, expensive and a distraction from our business.

If we do not adequately protect our intellectual property, competitors may be able to use our proprietary information to erode our competitive advantage, which could harm our business and operating results. Litigation may be necessary to enforce or determine the validity and scope of our proprietary rights, and there can be no assurance that our intellectual property rights, if challenged, will be upheld as valid. Such litigation could result in substantial costs and diversion of resources and could have a material adverse effect on our operating results, regardless of the outcome of the litigation. In addition, there can be no assurance that any of the patents issued to us will not be challenged, invalidated or circumvented or that the rights granted thereunder will provide competitive advantages to us.

There are no pending claims against us regarding infringement of any patents or other intellectual property rights of others. However, in the future we may receive communications from third parties asserting intellectual property claims against us. Such claims could include assertions that our products infringe, or may infringe, the proprietary rights of third parties, requests for indemnification against such infringement or suggestions that we may be interested in acquiring a license from such third parties. There can be no assurance that any such claim will not result in litigation, which could involve significant expense to us, and, if we are required or deem it appropriate to obtain a license relating to one or more products or technologies, there can be no assurance that we would be able to do so on commercially reasonable terms, or at all.

While we believe we have complied with all applicable environmental laws, our failure to do so could adversely affect our business as a result of having to pay substantial amounts in damages or fees.

Federal, state and local regulations impose various controls on the use, storage, discharge, handling, emission, generation, manufacture and disposal of toxic and other hazardous substances used in our operations. We believe that our activities conform in all material respects to current environmental and land use regulations applicable to our operations and our current facilities, and that we have obtained environmental permits necessary to conduct our business. Nevertheless, failure to comply with current or future regulations could result in substantial fines, suspension of production, alteration of our manufacturing processes or cessation of operations. Such regulations could require us to acquire expensive remediation equipment or to incur substantial expenses to comply with environmental regulations. Any failure to control the use, disposal or storage of or adequately restrict the discharge of, hazardous or toxic substances could subject us to significant liabilities.

If we fail to maintain effective internal control over financial reporting in the future, the accuracy and timing of our financial reporting may be adversely affected.

We are required to comply with Section 404 of the Sarbanes-Oxley Act of 2002. The provisions of the act require, among other things, that we maintain effective internal control over financial reporting and disclosure controls and procedures. Preparing our financial statements involves a number of complex processes, many of which are done manually and are dependent upon individual data input or review. These processes include, but are not limited to, calculating revenue, deferred revenue and inventory costs. While we continue to automate our processes and enhance our review and put in place controls to reduce the likelihood for errors, we expect that for the foreseeable future, many of our processes will remain manually intensive and thus subject to human error.
