NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Basis of Presentation

These unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted in these interim statements. Accordingly, these condensed consolidated financial statements are to be read in conjunction with the financial statements and notes included in the Company's Annual Report on Form 10-K for its fiscal year ended March 28, 2015. These interim statements include all adjustments (consisting of only normal recurring adjustments and accruals) necessary for a fair presentation of results for the interim periods presented. The results for interim periods are not necessarily indicative of the results of operations for the entire year.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of commitments and contingencies at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results may differ from those estimates.

Management believes that the estimates used are reasonable. Significant estimates made by management include: revenue recognition; inventory valuation; product warranty reserves; allowance for doubtful accounts; accrued restructuring costs; share-based compensation; income taxes including the valuation of deferred tax assets; fair value measurements; valuation of cost method equity investments; valuation of long-lived assets; valuation of goodwill; and valuation of acquired technology.

There have been no significant changes to the Company's significant accounting policies from those presented in Note 2 “Summary of Significant Accounting Policies” to the consolidated financial statements included in the Company's Annual Report on Form 10-K for its fiscal year ended March 28, 2015. All references to years or quarters relate to fiscal years or fiscal quarters unless otherwise noted.

In the first quarter of 2016, certain prior period amounts were revised to conform to current year presentation. Please see Note 7 "Trade Accounts Receivable" and Note 10 "Accrued Current Liabilities & Other Liabilities".

2. Recent Accounting Pronouncements

In June 2014, the FASB issued ASU No. 2014-12, "Compensation - Stock Compensation (Topic 718)." ASU No. 2014-12 addresses accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. ASU 2014-12 indicates that, in such situations, the performance target should be treated as a performance condition and, accordingly, the performance target should not be reflected in estimating the grant-date fair value of the award. Instead, compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. We do not expect the adoption of ASU 2014-12 to have a material effect on our financial position, results of operations or cash flows.

In April 2015, the FASB issued ASU 2015-05, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40).” ASU 2015-05 provides guidance regarding the accounting for a customer's fees paid in a cloud computing arrangement, specifically about whether a cloud computing arrangement includes a software license, and if so, how to account for the software license. ASU 2015-05 is effective for public companies' annual periods, including interim periods, beginning after December 15, 2015. Early adoption is permitted. We do not expect the adoption of ASU 2015-05 to have a material effect on our financial position, results of operations or cash flows.

In July 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-11, “Simplifying the Measurement of Inventory (Topic 330).” ASU 2015-11 simplifies the accounting for the valuation of all inventory not accounted for using the last-in, first-out (“LIFO”) method by prescribing inventory be valued at the lower of cost and net realizable value. ASU 2015-11 is effective for public companies' annual periods, including interim periods within those fiscal years, beginning after December 15, 2016 on a prospective basis. Early adoption is permitted. We do not expect the adoption of ASU 2015-11 to have a material effect on our financial position, results of operations or cash flows.

7

In August 2015, the FASB issued ASU No. 2015-14, which defers the effective date of ASU No. 2014-09 "Revenue from Contracts with Customers" one year to interim and annual reporting periods beginning after December 15, 2017. This guidance may be adopted retrospectively or under a modified retrospective method where the cumulative effect is recognized at the date of initial application. The Company is currently evaluating the impact of adopting this guidance on its Consolidated Financial Statements and disclosures included within Notes to Consolidated Financial Statements.

3. Share-Based Compensation

The Company recognizes expense related to the fair value of its share-based compensation awards using the Black-Scholes model to estimate the fair value of awards on the date of grant, except for unvested restricted stock unit awards which are valued at the fair value of the Company's stock on the date of award. The Company recognizes compensation expense for all share-based compensation awards on a straight-line basis over the requisite service period of the award.

Stock-settled stock appreciation rights (SARs) grant the right to receive shares of the Company's stock equivalent to the increase in stock value of a specified number of shares over a specified period of time, divided by the stock price at the time of exercise. Similar to options, SARs are measured at the fair value of the award on the grant date and the expense is recognized on a straight-line basis over the requisite service period of the award.

The Company granted a total of 703,700 restricted stock units (RSUs), 467,000 SARs, and zero stock options during the first two quarters of 2016. The Company granted 513,700 RSUs and 260,000 SARs, and zero stock options during the first two quarters of 2015.

Share-based compensation expense was included in the Company’s Condensed Consolidated Statements of Operations as follows:

	Fiscal quarter ended				Two fiscal quarters ended
(In thousands)	Sep 26, 2015		Sep 27, 2014		Sep 26, 2015		Sep 27, 2014
Cost of sales	$	114	$	151	$	243	$	320
Selling, general and administrative	746		602		1,461		1,467

Total share-based compensation expense	$	1,066	$	1,033	$	2,129	$	2,363

No share-based compensation costs were capitalized in the first two quarters of 2016. As of September 26, 2015, the Company had $9.1 million of total unrecognized share-based compensation costs, net of estimated forfeitures, which are expected to be recognized over a weighted average period of 2.2 years. The amounts shown in the table above for the fiscal quarter ended September 26, 2015 and two fiscal quarters ended September 26, 2015, do not include $173 thousand and $497 thousand, respectively, in expense related to acquisitions. Refer to Note 5 "Business Acquisitions" for discussion of stock amounts considered compensation related to acquisitions.

4. Fair Value Measurements

Financial Assets Measured at Fair Value

ASC Topic 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include the following:

• Level 1, defined as observable inputs such as quoted prices in active markets for identical assets or liabilities;

• Level 2, defined as inputs that are observable either directly or indirectly such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and other inputs that can be corroborated by observable market data; and

• Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The Company’s fair value hierarchy for its financial assets measured at fair value on a recurring basis as of September 26, 2015 and March 28, 2015 was as follows (in thousands):

Net unrealized holding gains and losses on current available-for-sale securities included in accumulated other comprehensive loss were insignificant as of September 26, 2015 and March 28, 2015.

Investments with underlying maturities within one year at September 26, 2015, including cash equivalents, totaled $29.2 million.

5. Business Acquisitions

Fiscal 2015

On January 15, 2015, the Company acquired all of the outstanding shares of Wuhan Topwin Optoelectronics Technology Co., Ltd. (Topwin), a Chinese manufacturer of laser-based systems and as of March 28, 2015 the company performed a preliminary determination and allocation of purchase price to the identifiable acquired assets and liabilities. In the first quarter of 2016, the Company finalized the determination of purchase price, including the valuation of total consideration and the related contractual adjustments to working capital, and valuation of acquired assets and assumed liabilities. Analysis supporting the purchase price allocation included a valuation of assets and liabilities as of the closing date, an analysis of intangible assets and a detailed review of the opening balance sheet to determine other significant adjustments required to recognize assets and liabilities at fair value. Consideration was comprised of $7.6 million in cash and 748,944 shares of ESI common stock issuable over a three year period, valued at approximately $2.9 million as of the acquisition date. Of the $2.9 million in equity, one-half, or 374,472 shares, is contingent-based consideration and one-half, or 374,472 shares, is non-contingent and will be issued over a three year period beginning June 30, 2015. The contingent consideration is based on future performance of Topwin, as evaluated against targets for net income for each year over a three year period. One-third of the contingent shares will be issued after each year if the target is met for that year; however failing to meet stated targets will result in none of the contingent shares being issued for that year. As of the acquisition date, the fair value of the contingent consideration was estimated to be $0.4 million and of the 374,472 shares of non-contingent consideration was estimated to be $2.5 million. The fair value of the non-contingent and contingent shares was determined based on the estimated share price as of the issuance date derived through Monte Carlo simulation, discounted back to the acquisition date. The value of the contingent shares included consideration of the estimated probability of attainment of the net income targets. Additionally, the Company will issue, on the same terms described above, approximately 513,328 shares valued at $2.0 million, which, together

10

with cash amounts of $0.2 million, is treated as compensation to a Principal in the Company who was also a former shareholder of Topwin. Compensation expense will be recognized over the Principal's term of employment or related service period required by the purchase agreement through December 31, 2017. In the first two quarters of fiscal 2016, we have recognized approximately $0.5 million in compensation expense related to this agreement, comprised primarily of share-based compensation.

The total purchase price of approximately $10.5 million, net of cash acquired, was allocated to the underlying assets acquired and liabilities assumed based on their fair values, as shown in the following table:

(In thousands)
Accounts receivable	$	454
Inventory	544
Prepaid expense and other current assets	295
Property, plant and equipment	23
Acquired intangibles	3,618
Goodwill	7,445
Accounts payable and other accrued liabilities	(1,859		)
Total purchase price, net of cash acquired	$	10,520

The acquisition is expected to enable the Company to gain entry into the low total-cost-of-ownership solutions market in China and the goodwill of approximately $7.4 million recognized as a result of the acquisition was assigned to the Topwin reporting unit. The premium paid over the fair value of the individual assets acquired and liabilities assumed reflects the Company’s view that this acquisition was the result of a competitive bid process and has provided the Company with innovative design and manufacturing capabilities for laser-based manufacturing solutions across a variety of complementary applications, together with direct access to local China market, supply chain and opto-electronics knowledge center. None of the goodwill is expected to be deductible for tax purposes.

As a result of the acquisition, the Company recorded approximately $4.9 million of identifiable assets, including $3.6 million of identifiable intangible assets, and $1.9 million of identifiable liabilities. The acquired intangible assets consist primarily of $3.5 million of developed technology and will be amortized over their useful lives, which range from one to ten years.

In the first two quarters of 2016, the Company incurred approximately $0.2 million in acquisition-related costs. In 2015, the Company incurred approximately $0.8 million in acquisition-related costs which were included in Selling, general and administrative expenses in the Consolidated Statements of Operations. The operating results of this acquisition are included in the Company’s results of operations since the date of acquisition. Pro forma financial information has not been provided for the acquisition of Topwin as it was not material to the Company’s operations and overall financial position.

Product warranty accrual, ending	$	4,451		$	3,152		$	4,451		$	3,152

12

Net warranty charges incurred include labor charges and costs of replacement parts for system repairs under warranty. These costs are recorded net of any estimated cost recoveries resulting from either successful repair of damaged parts or from warranties offered by the Company’s suppliers for defective components. The provision for warranty charges reflects the estimate of future anticipated net warranty costs to be incurred for all products under warranty at quarter end and is recorded to cost of sales. Of the total of $4.5 million in product warranty accrual at September 26, 2015, $1.2 million is non-current and is included in Other liabilities on the Condensed Consolidated Balance Sheets.

12. Deferred Revenue

Generally, revenue is recognized upon fulfillment of acceptance criteria at the Company's factory and transfer of risk and title. Revenue is deferred whenever title transfer is pending, risk has not transferred, and/or acceptance criteria have not yet been fulfilled. Deferred revenue occurrences include sales to Japanese customers, shipments of substantially new products and shipments with custom specifications and acceptance criteria. In sales involving multiple element arrangements, the relative selling price of any undelivered elements, including installation services, is deferred until the elements are delivered and acceptance criteria are met. Revenue related to maintenance and service contracts is deferred and recognized ratably over the duration of the contracts.

The following is a reconciliation of the changes in deferred revenue:

	Fiscal quarter ended						Two fiscal quarters ended
(In thousands)	Sep 26, 2015			Sep 27, 2014			Sep 26, 2015			Sep 27, 2014

Deferred revenue, ending	$	12,662		$	16,440		$	12,662		$	16,440

13. Commitments & Contingencies

On March 20, 2015, the Company entered into a loan and security agreement ("Loan Agreement") with Silicon Valley Bank, as lender. The Loan Agreement provides for a senior secured asset-based revolving credit facility (the “Credit Facility”) with up to $30 million available on a revolving basis, including a $15 million sublimit for letters of credit. The credit agreement expires March 20, 2018. At September 26, 2015, we had no revolving loans or letters of credit outstanding under our Credit Facility, we were in compliance with all covenants, and were not in default under the Loan Agreement. The commitment fee on the amount of unused credit was 0.3 percent.

We mitigate credit risk by transacting with highly rated counterparties for foreign exchange contracts, letters of credit and other transactions where counterparty risk is a factor. We have evaluated the non-performance risks associated with our lenders and other parties and believe them to be insignificant. From time to time we may be party to litigation arising in the normal course of business. Currently we are not party to any litigation we believe would have a material adverse effect on our financial position, results of operations, or cash flows.

14. Loss Per Share

The following is a reconciliation of weighted average shares outstanding used in the calculation of basic and diluted earnings per share:

	Fiscal quarter ended						Two fiscal quarters ended
(In thousands, except per share data)	Sep 26, 2015			Sep 27, 2014			Sep 26, 2015			Sep 27, 2014
Net loss	$	(3,260	)	$	(6,243	)	$	(9,624	)	$	(14,494	)
Weighted average shares used for basic earnings per share	31,384			30,552			31,280			30,452
Weighted average shares used for diluted earnings per share	31,384			30,552			31,280			30,452
Net loss per share:
Net loss — basic	$	(0.10	)	$	(0.20	)	$	(0.31	)	$	(0.48	)
Net loss — diluted	$	(0.10	)	$	(0.20	)	$	(0.31	)	$	(0.48	)

13

Awards of stock options, SARs and unvested RSUs representing an additional 3.7 million and 2.8 million shares of stock for the second quarter of 2016 and 2015, respectively, were not included in the calculation of diluted net earnings per share because their effect would have been antidilutive.

15. Segment and Geographic Information

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is our Chief Executive Officer. Prior to the fourth quarter of 2015, we operated in one segment, high-technology manufacturing equipment, which was comprised of products that were classified in three groups: interconnect and micromachining, semiconductor and component. As a result of changes in our go-to-market strategies, common customer characteristics, and information utilized to manage our business, we realigned our products into two segments. Since the fourth quarter 2015 the Company has operated in two segments, Component Processing and Micromachining.

Net sales by segment were as follows:

	Fiscal quarter ended				Two fiscal quarters ended
(In thousands)	Sep 26, 2015		Sep 27, 2014		Sep 26, 2015		Sep 27, 2014

16. Restructuring and Cost Management Plans

In March 2015, as a part of the plan to streamline its manufacturing and development activities, the Company initiated a restructuring plan to close the assembly plant and development center located in Chelmsford, Massachusetts. The estimated completion date of the plan is the end of fiscal 2016. See the Company's Form 10-K for the year ended March 28, 2015 for additional information related to restructuring and cost management plans.

Net restructuring costs of $0.7 million in the first two quarters of 2016 included severance and wind-up costs. These costs relate to the restructuring plan described above and our previously disclosed action to close our Beijing facility. At September 26, 2015 and March 28, 2015, the amount of unpaid restructuring costs included in accrued liabilities was $1.6 million and $2.0 million, respectively.

The following table presents the amounts related to restructuring costs payable (in thousands):

17. Shareholders’ Equity

Share Repurchase Program

In December 2011, the Board of Directors authorized a share repurchase program totaling $20.0 million to acquire shares of our outstanding common stock. The repurchases are to be made at management’s discretion in the open market or in privately negotiated transactions in compliance with applicable securities laws and other legal requirements and are subject to market conditions, share price and other factors.

The Company did not repurchase any shares during the first two quarters of 2016. In the first two quarters of 2015 the Company repurchased 207,738 shares for $1.5 million under this authorization at an average price of $7.01 per share, calculated inclusive of commissions and fees.

There is no fixed completion date for the repurchase program.

Dividends

In February 2015, the Board of Directors suspended the quarterly dividend which was adopted by the Company in December 2011. The Company paid dividends in the first three quarters of 2015 under the 2011 dividend policy in the aggregate amount of $0.24 per share.

Overview of Business

Electro Scientific Industries, Inc. and its subsidiaries (ESI) is a leading supplier of innovative laser-based manufacturing solutions for the microtechnology industry. ESI's integrated solutions allow industrial designers and process engineers to control the power of laser light to transform materials in ways that differentiate their consumer electronics, wearable devices, semiconductor circuits and high-precision components for market advantage. ESI’s laser-based manufacturing solutions feature the micro-machining industry’s highest precision and speed, and target the lowest total cost of ownership. Founded in 1944, ESI is headquartered in Portland, Oregon, with global operations from the Pacific Northwest to the Pacific Rim.

Laser microfabrication is comprised of a set of precise micron-level processes, including drilling, scribing, dicing, singulation, cutting, ablating, trimming, and precision marking on multiple types of materials. These processes require application-specific laser systems that are able to meet our customers’ exacting performance and productivity requirements. Our laser-based systems are utilized in the production of consumer electronics, flexible and rigid printed circuit boards, semiconductor devices, advanced semiconductor packaging, electronic sensors, touch-panel glass, flat panel liquid crystal displays (LCDs) and other high value components and devices to enable functionality, increase performance and improve production yields.

Additionally, we produce high-capacity test and inspection equipment that is critical to the quality control process during the production of multilayer ceramic capacitors (MLCCs). Our equipment ensures that each component meets the electrical and physical tolerances required to perform properly.

Historically and during much of fiscal 2015 we operated in one segment, high technology manufacturing equipment, which was comprised of products classified into three groups: interconnect and micromachining, semiconductor, and component test. As a result of changes in our go-to-market strategies, common customer characteristics, and information

15

utilized to manage our business, during the fourth quarter of 2015 we realigned our products into two segments: Component Processing (CP) and Micromachining (MM). Included within Component Processing are Interconnect Products (IP), Semiconductor Products (SP), and Component Test Products (CTP), which are sold primarily to manufacturers of electronic components to drill, cut, trim, ablate, test and mark features that improve the yield or functionality of the component. Micromachining Products (MP) are sold primarily to manufacturers of end devices across multiple industries and are used to drill, cut, or mark features on a variety of materials, generally on the casing or external surfaces of the end device. ESI does not maintain or monitor operating expenses or assets at the segment level.

Summary of Sequential Quarterly Results

The financial results of the second quarter of 2016 ended September 26, 2015, reflected sequential growth in orders, sales and earnings. Total order volume for the second quarter of 2016 increased to $51.5 million from $41.9 million in the first quarter, primarily driven by application wins in the MM segment, strength in the flex market and inclusion of a legacy memory repair order. Net sales increased to $46.5 million from $43.1 million in the first quarter of 2016 which ended June 27, 2015.

CP segment sales decreased to $32.8 million in second quarter of 2016 from $38.3 million in the prior quarter. The decrease relates to higher sales of Semiconductor and Component Test products in the prior quarter that did not recur at the same level in the current quarter, primarily due to timing of orders for wafer processing and wafer trim systems, lower service revenue, and customers' near term capital budget reductions for MLCC systems. Sales remained relatively flat for Interconnect products. Sales in the MM segment grew substantially to $13.7 million in the second quarter of 2016 compared to $4.8 million in the first quarter, fueled primarily by an application win for the Lumen series micromachining platform.

Total shipments were $44.0 million in the second quarter of 2016 compared to $46.2 million in the first quarter of 2016.

Gross profit was $18.4 million in the second quarter of 2016 compared to a gross profit of $15.4 million in the first quarter of 2016. This increase was primarily due to increased sales and production volumes, combined with gross margin improvement. Gross margin was 39.6% on net sales of $46.5 million in the second quarter of 2016 compared to a gross margin of 35.7% on net sales of $43.1 million in the first quarter of 2016. The gross margin improvement was primarily driven by more beneficial product mix, lower material costs, decreases in service repair expenses, and improved warranty cost.

Net operating expense of $21.4 million in the second quarter of 2016decreased slightly from $21.5 million in the first quarter of 2016, the result of cost savings efforts largely offset by $0.6 million in restructuring charges incurred in the second quarter. Research, development, and engineering (RD&E) decreased $0.4 million primarily due to headcount reductions. Selling, general and administrative (SG&A) expenses decreased $0.1 million primarily due to cost savings efforts.

Operating loss was $3.0 million in the second quarter of 2016 compared to an operating loss of $6.1 million in the first quarter of 2016, a decrease of $3.1 million. The decrease in operating loss was principally due to higher sales volumes and improved gross margins, combined with lower operating expenses.

Provision for income taxes was $0.2 million in the second quarter of 2016 compared to a provision of $0.3 million in the first quarter of 2016.

Net loss was $3.3 million in the second quarter of 2016 compared to a net loss of $6.4 million in the first quarter of 2016.

Net sales for the second quarter of 2016increased$3.6 million or 8.4% from net sales for the second quarter of 2015. Sales in the CP and MM segments increased by 1.2% and 30.7% respectively.

CP segment sales for the second quarter of 2016increased$0.4 million compared to the second quarter of 2015. The increase in CP segment sales was driven by increased demand for our flex via drilling products, including the new GemStone product, partially offset by lower sales for wafer trim, repair activity, and MLCC systems.

MM segment sales for the second quarter of 2016increased$3.2 million compared to the second quarter of 2015. The increase was driven by an application win for our new Lumen series platform.

Gross Profit	$	18,421		39.6	%	$	14,765		34.5	%

Gross profit was $18.4 million for the second quarter of 2016, an increase of $3.7 million compared to the second quarter of 2015. The gross profit increase was principally due to higher sales volume. Gross margins were 39.6% and 34.5% for the second quarters of 2016 and 2015, respectively. The higher gross margin is due primarily to beneficial changes in sales mix, the positive impact of higher volumes and lower manufacturing costs.

Gross margin for the CP segment increased slightly from 40.5% to 40.9% on slight volume increases. MM segment gross margins increased from 19.4% to 39.9% due to significant volume and mix improvements, driven principally by increased sales of the Lumen series platform, as well as general reductions in manufacturing expenses and decreased repair costs. Additionally, fixed costs are allocated between segments based on annual business levels as projected at the beginning of each year, resulting in lower costs allocated to the MM segment in the second quarter 2016 compared to the second quarter of 2015.

	$	21,448	46.2	%	$	20,323	47.5	%

Selling, General and Administrative

Selling, general and administrative (SG&A) expenses primarily consist of labor and other employee-related expenses including share-based compensation expense, travel expenses, professional fees, sales commissions and facilities costs.

SG&A expenses for the second quarter of 2016increased$0.6 million compared to the second quarter of 2015. This increase was attributable to increases in variable pay, stock compensation and Topwin-related expenses in the second quarter of 2016.

Research, Development and Engineering

Research, development and engineering (RD&E) expenses are primarily comprised of labor and other employee-related expenses, professional fees, project materials costs, equipment costs and facilities costs. RD&E expenses for the second quarter of 2016decreased$0.1 million compared to the second quarter of 2015. This decrease was primarily due to labor cost reductions.

Acquisition and Integration Costs

Acquisition and integration costs consisted mainly of consulting, travel and legal expenses associated with the acquisition and integration of Topwin Optoelectronics, which was acquired in January 2015.

Restructuring Costs

Restructuring costs of $0.6 million consisted primarily of expenses associated with actions to reduce labor cost and transition resources to Asia. We anticipate the restructuring activities to conclude in the third quarter of 2016 and we expect to incur approximately $1.5 million to $2.0 million of restructuring costs primarily associated with consolidation of our facilities.

Interest and other income, net, consists primarily of net interest income and expense, market gains and losses on assets held in employees’ deferred compensation accounts, realized and unrealized foreign exchange gains and losses, bank charges and investment management fees. Net interest and other income was $6 thousand in the second quarter of 2016 compared to expense of $244 thousand in second quarter of 2015. The improvement was primarily due to foreign exchange losses in the second quarter of 2015, which did not repeat.

The provision for income taxes for the second quarter of 2016 was $0.2 million on the pretax loss of $3.0 million, an effective tax rate of (7.9)% resulting primarily from foreign taxes. For the second quarter of 2015, the provision for income taxes was $0.4 million on pretax loss of $5.8 million, an effective rate of (7.6)%. The negative tax rate is driven by income tax in foreign jurisdictions, despite pretax losses for the Company as a whole.

Net sales for the first two quarters of 2016increased$11.7 million or 15.0% from net sales for the first two quarters of 2015. Sales in CP increased by $8.4 million or 13.4% and MP increased by $3.3 million or 21.6%.

The increase in CP sales for the first two quarters of 2016 compared to the first two quarters of 2015 was primarily due to a $9.8 million improvement in Interconnect sales resulting from higher demand for our flex products. This increase was partially offset by lower sales of circuit trim systems.

The increase in MP sales for the first two quarters of 2016 compared to the first two quarters of 2015 was primarily driven by increased sales volume for new applications of our Lumen series platform.

Gross profit was $33.8 million for the first two quarters of 2016 and increased$6.7 million compared to the first two quarters of 2015. Gross profit improved primarily due to overall increased sales volume, favorable product mix and favorable repair activity. Gross margins for the CP segment decreased slightly from 41.0% to 38.7% on higher warranty costs. MM segment gross margins increased from 15.6% to 38.5% due to significant volume and mix improvements, driven principally by increased sales of the Lumen series platform, as well as general reductions in manufacturing expenses and decreased repair costs. Additionally, fixed costs are allocated between segments based on annual business levels as projected at the beginning of each year, resulting in lower costs allocated to the MM segment in the first two quarters of 2016 compared to the first two quarters2015.

	$	42,926	47.9	%	$	41,621	53.4	%

Selling, General and Administrative

Selling, general and administrative (SG&A) expenses primarily consist of labor and other employee-related expenses including share-based compensation expense, travel expenses, professional fees, sales commissions and facilities costs.

SG&A expenses for the first two quarters of 2016increased$1.1 million compared to the first two quarters of 2015. This change was attributable to increases in variable pay, stock compensation and Topwin-related expenses in 2016 as compared to 2015, somewhat mitigated by cost savings efforts in other areas such as professional services and consulting.

Research, Development and Engineering

Research, development and engineering (RD&E) expenses are primarily comprised of labor and other employee-related expenses, professional fees, project materials costs, equipment costs and facilities costs. RD&E expenses for the first two quarters of 2016decreased$0.6 million compared to the first two quarters of 2015. This decrease was primarily due to labor cost reductions.

Acquisition and Integration Costs

Acquisition and integration costs consisted mainly of consulting, legal and travel expenses associated with the acquisition and integration of Topwin Optoelectronics, which was acquired in January 2015.

Restructuring Costs

Restructuring costs consisted primarily of expenses associated with severance costs related to further efforts to shift resources to Asia and lower overall costs. We anticipate the restructuring activities to conclude in the third quarter of 2016 and we expect to incur approximately $1.5 million to $2.0 million of restructuring costs primarily associated with consolidation of our facilities.

Interest and other income, net, consists primarily of interest income and expense, market gains and losses on assets held in employees’ deferred compensation accounts, realized and unrealized foreign exchange gains and losses, bank charges and investment management fees. Net interest and other expense was negligible for the first two quarters of 2016 compared to net interest and other expense of $0.2 million in the first two quarters of 2015. This improvement was primarily due to foreign exchange losses in 2015 which did not repeat, partially offset by increased market losses on assets held in deferred compensation accounts in 2016.

For the first two quarters of 2015, the income tax benefit was $0.3 million on pretax loss of $14.8 million, an effective rate of 1.8%. The provision for taxes in 2016 relates to income taxes arising in foreign jurisdictions and the net income tax benefit in 2015 was driven by a favorable tax assessment related to the legal settlement with All Ring.

Net loss	$	(9,624	)	(10.7	)%	$	(14,494	)	(18.6	)%

Net loss for the first two quarters of 2016 was $9.6 million, or $0.31 per basic and diluted share, compared to net loss of $14.5 million, or $0.48 per basic and diluted share for the first two quarters of 2015.

Financial Condition and Liquidity

At September 26, 2015, our principal sources of liquidity were cash and cash equivalents of $43.6 million, short-term investments of $16.6 million and current accounts receivable of $49.1 million. At September 26, 2015, we had a current ratio of 3.40 and had no outstanding debt. Working capital of $122.4 million decreased $2.2 million compared to the March 28, 2015 balance of $124.6 million, substantially impacted by operating losses in the first two quarters of 2016.

In February 2015, the Board of Directors suspended the quarterly dividend which was adopted by the Company in December 2011. The Company paid dividends in the first three quarters of 2015 under the 2011 dividend policy in the aggregate amount of $0.24 per share. The Company did not pay any dividends in the first two quarter of 2016.

Sources and Uses of Cash

Net cash provided by operating activities of $4.5 million for the two quarters endedSeptember 26, 2015 was a result of $9.6 million of net loss, or $2.2 million in losses after adjusting for non-cash items, more than offset by cash flow improvements related to changes in working capital. Significant changes in working capital in the first two quarters of 2016 consisted of a $9.8 million increase in accounts payable driven by normalization of timing of inventory receipts and extension of payment terms with certain vendors, somewhat offset by a $6.8 million increase in accounts receivable driven by higher shipments, and a $1.4 million increase in inventories.

Net cash used in investing activities of $11.8 million was primarily the result of $10.0 million of net purchases of investments and $2.2 million of capital expenditures for purchases of property, plant and equipment (PP&E). Accounts payable balance includes $0.2 million for amounts owed on PP&E purchases as of September 26, 2015.

22

For the first two quarters of 2016, net cash provided by financing activities of $0.1 million related to issuances from employee stock plans, net of payments of associated withholding taxes.

We believe that our existing cash, cash equivalents and short-term investments are adequate to fund our operations and contractual obligations for at least the next twelve months.

Item 1A. Risk Factors

The statements contained in this report that are not statements of historical fact, including without limitation statements containing the words “believes,” “expects” and similar words, constitute forward-looking statements that are subject to a number of risks and uncertainties. From time to time, we may make other forward-looking statements. Investors are cautioned that such forward-looking statements are subject to an inherent risk that actual results may differ materially. The following information highlights some of the factors that could cause actual results to differ materially from the results expressed or implied by our forward-looking statements. Forward-looking statements should be considered in light of these factors. Factors that may result in such variances include, but are not limited to, the following:

Risks Related to Our Competition and Customers

Volatility of Our Customers’ Industries

Our business is dependent upon the capital expenditures of manufacturers of microelectronics, semiconductors, computers, wireless communications and other electronic products. The capital equipment market for microelectronics, semiconductor, and consumer electronics manufacturers has historically been characterized by sudden and severe cyclical variations in product supply and demand due to a number of factors including capacity utilization, timing of customers’ new product introductions and demand for their products, inventory levels relative to demand and access to affordable capital. The timing, severity and duration of these market cycles are difficult or impossible to predict. As a result, business levels can vary significantly from quarter to quarter or year to year. Significant volatility in investment cycles in the market for

23

microelectronics, PCB's and semiconductors used in electronic devices or in the market for consumer electronics reduce demand for our products and may materially and adversely affect our business, financial condition and results of operations. The degree of the impact of any downturn on our business depends on a number of factors, including: the strength of the global economies, particularly those of Asia and the United States; the overall level of demand for consumer electronics products; the stability of global financial systems; and the overall health of the microelectronics, semiconductor, and consumer electronics industries.

Expansion into New Markets

Our future success depends in large part on our successful penetration of new markets adjacent to our existing markets and of the Chinese market for lower cost systems. These markets are new to us and our success is dependent on our displacing entrenched competitors who are familiar with these markets and are known to customers. There is no assurance that we will be successful in penetrating these new markets significantly or at all. If we fail to successfully penetrate these markets our business, financial condition and results of operations could be materially and adversely affected.

Highly Competitive Markets

We face substantial competition from established competitors throughout the world, some of which have greater financial, engineering, manufacturing and marketing resources than we do. Those competitors with greater resources may, in addition to other things, be able to better withstand periodic downturns, compete more effectively on the basis of price and technology, or more quickly develop enhancements to, and new generations of, products that compete with the products we manufacture and market. New companies may enter the markets in which we compete, or industry consolidation may occur, further increasing competition in those markets. We have also experienced new entrants to our markets offering aggressive price and payments terms in an attempt to gain market share. Some competitors, particularly in China, also develop low cost products employing processes or technology developed by us. We believe that to be competitive we must continue to expend significant financial resources in order to, among other things, invest in new product development and enhancements. We may not be able to compete successfully in the future and increased competition may result in price reductions, reduced profit margins and loss of market share.

Revenues are Largely Dependent on Few Customers

We depend on a few significant customers for a large portion of our revenues. In 2015, our top ten customers accounted for approximately 40% of total net sales. We anticipate that sales of our products to a relatively small number of customers will continue to account for a significant portion of our revenues. Consolidation between customers, changes in technologies or solutions used by customers, changes in products manufactured by customers or in end-user demand for those products, selection of suppliers other than us, customer bankruptcies or customer departures from their respective industries all may result in even fewer customers accounting for a high percentage of our revenue and reduced demand from any single major customer. Also, business levels with several of our top customers are dependent on our winning new designs and features each product cycle, and there is no guarantee of future business based on past design wins. Furthermore, none of our customers have any long-term obligation to continue to buy our products or services and may therefore delay, reduce or cease ordering our products or services at any time. The cancellation, reduction or deferral of purchases of our products by even a single customer could significantly reduce our revenues in any particular quarter. For example, revenues from Apple, Inc. decreased from $27 million in 2014 to $15 million in 2015. If we were to lose any of our significant customers or suffer a material reduction in their purchase orders, revenue could decline and our business, financial condition and results of operations could be materially and adversely affected.

Increased Price Pressure

We have experienced and continue to experience pricing pressure in the sale of our products, from both competitors and customers. Pricing pressures typically have become more intense during cyclical downturns when competitors seek to maintain or increase market share, reduce inventory or introduce more technologically advanced products or lower cost products. In addition, we may agree to pricing concessions or extended payment terms with our customers in connection with volume orders or to improve cost of ownership in highly competitive applications. Our business, financial condition, margins or results of operations may be materially and adversely affected by competitive pressure and intense price-based competition.

Revenues are Largely Based on the Sale of a Small Number of Product Units

We derive a substantial portion of our revenue from the sale of a relatively small number of products. Accordingly, our revenues, margins and other operating results could fluctuate significantly from quarter to quarter depending upon a variety of factors in addition to those described above, including:

• changes in the timing of orders and terms or acceptance of product shipments by our customers;

• changes in the mix of products and services that we sell;

• timing and market acceptance of our new product introductions; and

24

• delays or problems in the planned introduction of new products, or in the performance of any such products following delivery to customers.

As a result of these risks, we believe that quarter-to-quarter comparisons of our revenue and operating results may not be meaningful, and that these comparisons may not be an accurate indicator of our future performance.

Risks Related to Our Supply Chain and Production

Variability of Production Capacity

To meet rapidly changing demand in the industries we serve, we must effectively manage our resources and production capacity. During periods of decreasing demand for our products, we must be able to appropriately align our cost structure with prevailing market conditions and effectively manage our supply chain. Our ability to rapidly and effectively reduce our cost structure in response to such downturns is limited by the fixed nature of many of our expenses in the near term and by our need to continue our investment in next-generation product technology and to support and service our products. Conversely, when upturns occur in the markets we serve, we may have difficulty rapidly and effectively increasing our manufacturing capacity or procuring sufficient materials to meet sudden increases in customer demand that could result in the loss of business to our competitors and harm to our relationships with our customers. If we are not able to timely and appropriately adapt to changes in our business environment, our business, financial condition or results of operations may be materially and adversely affected.

Reliance on Critical Suppliers

We use a wide range of components from numerous suppliers in the manufacture of our products, including custom electronic, laser, optical and mechanical components. We generally do not have guaranteed supply arrangements with our suppliers. We seek to reduce the risk of production and service interruptions and shortages of key parts by selecting and qualifying alternative suppliers for key parts, monitoring the financial stability of key suppliers and maintaining appropriate inventories of key parts. Although we make reasonable efforts to ensure that parts are available from multiple suppliers, some key parts are available only from a single supplier or a limited group of suppliers in the short term. In addition, some of the lasers we use in our products are difficult to manufacture, and as a result we may not receive an adequate supply of lasers in a timely fashion to fill orders. Operations at our suppliers’ facilities are subject to disruption or discontinuation for a variety of reasons, including changes in business relationships, competitive factors, financial difficulties, work stoppages, fire, natural disasters or other causes. Any such disruption or discontinuation to our suppliers’ operations could interrupt or reduce our manufacturing activities and delay delivery of our products, any or all of which could materially and adversely affect our results of operations. In addition, when markets recover from economic downturns, there is a heightened risk that one or more of our suppliers may not be able to meet our increased demand requirements, adversely impacting our ability to fulfill orders and win business with our customers.

Utilization of Contract Manufacturers

We have arrangements with contract manufacturers to complete the manufacturing of certain of our product subcomponents. Any significant interruption in our contract manufacturers’ ability to provide manufacturing services to us as a result of contractual disputes with us or another party, labor disruptions, financial difficulties, natural disasters, delay or interruption in the receipt of inventory, customer prioritization or other causes could result in reduced manufacturing capabilities or delayed deliveries for certain of our products, any or all of which could materially and adversely affect our results of operations.

Charges for Excess or Obsolete Inventory

One factor on which we compete is the ability to ship products on schedules required by customers. In order to facilitate timely shipping, management forecasts demand, both in type and amount of products, and these forecasts are used to determine inventory to be purchased. We also order materials based on our technology roadmap, which represents management’s assessment of technology that will be utilized in new products that we develop. Certain types of inventory, including lasers and optical equipment, are particularly expensive and may only be used in the production of a single type of product. If actual demand is lower than forecast with respect to the type or amount of products actually ordered, or both, our inventory levels may increase. As a result, there is a risk that we may have to incur material accounting charges for excess and obsolete inventory if inventory cannot be used, which would negatively affect our financial results. Also, if we alter our technology or product development strategy, we may have inventory that may not be usable under the new strategy, which may also result in material accounting charges. For example, during 2015, we recorded approximately $1.0 million of charges in cost of sales for inventory written-off associated with discontinued products.

Uncertainties Resulting from Conflict Minerals Regulation

25

On August 22, 2012, the SEC adopted a new rule requiring disclosures of specified minerals, known as conflict minerals, that are necessary to the functionality or production of products manufactured or contracted to be manufactured by companies filing public reports. The rule requires a disclosure report to be filed annually with the SEC and this report will require companies to perform due diligence, disclose, and report whether such minerals originate from the Democratic Republic of Congo or an adjoining country. The new rule could affect sourcing at competitive prices and availability in sufficient quantities of certain minerals used in the manufacture of our products, including tantalum, tin, gold, and tungsten. The number of suppliers who provide conflict-free minerals may be limited. In addition, there may be material costs associated with complying with the disclosure requirements, such as costs related to determining the source of certain minerals used in our products, as well as costs of possible changes to products, processes, or sources of supply as a consequence of such verification activities. Since our supply chain is complex, we may not be able to sufficiently verify the origins of the relevant minerals used in our products through the due diligence procedures that we implement, which may harm our reputation. In addition, we may encounter challenges to satisfy those customers who require that all of the components of our products be certified as conflict-free, which could place us at a competitive disadvantage if we are unable to do so.

Risks Related to Our Organization

Operating a Global Business

International shipments accounted for 86% of net shipments in 2015, with 76% of our net shipments to customers in Asia. We expect that international shipments will continue to represent a significant percentage of net sales in the future. We also have significant foreign operations, including manufacturing facilities in Singapore and China, research and development facilities in Canada, France and Taiwan, and sales and service offices in various countries. Under our globalization strategy, we intend to increase our foreign operations in the future. Our non-U.S. sales, purchases and operations are subject to risks inherent in conducting business abroad, many of which are outside our control, including the following:

• periodic local or geographic economic downturns and unstable political conditions;

• price and currency exchange controls;

• fluctuation in the relative values of currencies;

• difficulty in repatriating money, whether as a result of tax laws or otherwise;

• difficulties protecting intellectual property;

• compliance with labor laws and other laws governing employees;

• local labor disputes;

• shipping delays and disruptions;

• unexpected changes in trading policies, regulatory requirements, tariffs and other barriers; and

• difficulties in managing a global enterprise, including staffing, collecting accounts receivable, and managing suppliers, distributors and representatives.

Our business and operating results could also be impacted, directly or indirectly, by natural disasters, outbreaks of infectious disease, military action, international conflicts, terrorist activities, civil unrest and associated political instability. Many of our facilities, including our Portland, Oregon headquarters, are in areas with known earthquake risk. Some of these events or circumstances may also result in heightened security concerns with respect to domestic and international travel and commerce, which may further affect our business and operating results. In particular, due to these uncertainties, we are subject to the following additional risks:

• future tightening of immigration controls may adversely affect the residence status of non-U.S. engineers and other key technical employees in our U.S. facilities or our ability to hire new non-U.S. employees in such facilities;

• more frequent instances of shipping delays;

• demand for our products may not increase or may decrease; and

• our customers or suppliers may experience financial difficulties or cease operations.

Implementation and Modification of Globalization Strategy

We are continuing to implement and expand our globalization strategy in which we are moving certain operational resources and capabilities to different countries in Asia to be closer to many of our significant customers to reduce costs and to develop low cost follow-on solutions to our products. As part of this strategy we acquired Topwin, a Chinese manufacturer of laser-based systems, in January 2015 to gain entry into the low-cost solutions market in China.

We believe this strategy will enhance customer relationships, improve our responsiveness, reduce our manufacturing costs for certain products and allow us to compete with low cost competitors who develop systems employing processes developed by us. We opened a manufacturing facility in Singapore in the fourth quarter of 2010, which manufactures certain IP, MP, SP and CTP products and is now our primary system manufacturing facility.

26

Our globalization strategy is subject to a variety of complexities and risks, many of which may divert a substantial amount of management’s time. These risks include:

• challenges in designing facilities that can be scaled for future expansion, replicating current processes and bringing new facilities up to full operation;

• unpredictable costs, redundancy costs and cost overruns for developing facilities and acquiring equipment;

• building local management teams, technical personnel and other staff for functions that we have not previously conducted outside of the United States;

• technical obstacles such as poor production or process yield and loss of quality control during the ramp of a new facility;

• re-qualifications and other procedures that may be required by our customers;

• our ability to bring up local suppliers to meet our quality and cycle-time needs;

• our ability to reduce costs in the United States as we add costs elsewhere;

• rapidly changing business conditions that may require plans to be changed or abandoned before they are fully implemented; and

• challenges posed by distance and by differences in language and culture.

These and other factors could delay the continuing development, expansion and implementation of our strategy, as well as impair our gross margins, delay shipments and deliveries, cause us to lose sales, require us to write off investments already made, damage our reputation and harm our business, financial condition and results of operations. If we decide to change our globalization strategy, we may incur charges for certain costs incurred.

Acquisitions and Divestitures

We may make acquisitions of, or significant investments in, other businesses with complementary products, services or technologies, such as our June 2012 acquisition of Eolite Systems, our May 2013 acquisition of the Semiconductor Systems business from GSI Group, Inc. and our January 2015 acquisition of Topwin. Acquisitions involve numerous risks, many of which are unpredictable and beyond our control, including:

• difficulties and increased costs in connection with integration of personnel, operations, technologies and products of the acquired businesses;

• difficulties in implementation of our enterprise resource planning (ERP) system into the acquired company’s operations;

• diversion of management’s attention from other operational matters;

• the potential loss of key employees of the acquired company;

• lack of synergy or inability to realize expected synergies resulting from the acquisition;

• the inability to successfully enter new markets expected to result from the acquisition;

• acquired assets becoming impaired as a result of technological advancements or worse-than-expected performance by the acquired company;

• difficulties establishing satisfactory internal controls and accounting practices at the acquired company;

• risks related to the culture, language, and local practices of the acquired company;

• risks and uncertainties relating to the performance of the combined company following the transaction; and

• acquiring unanticipated liabilities for which we will not be indemnified.

Furthermore, the accounting for an acquisition could result in significant charges resulting from amortization or write-off of intangible assets and goodwill we acquire. Our inability to effectively manage these risks could result in our inability to realize the anticipated benefits of an acquisition on a timely basis, or at all, and materially and adversely affect our business, financial condition and results of operations. In addition, all acquisition transaction costs must be expensed as incurred rather than capitalized, which may have a material adverse effect on our results of operations.

The means by which we finance an acquisition may also significantly affect our business or the value of the shares of our common stock. If we issue common stock to pay for an acquisition, the ownership percentage of our existing shareholders will be diluted and the value of the shares held by our existing shareholders could be reduced. If we use cash on hand to pay for an acquisition, the payment could significantly reduce the cash that would be available to fund our operations or to use for other purposes. If we borrow funds in connection with an acquisition, we would be required to use cash to service the debt and to comply with financial and other covenants.

Hiring and Retention of Personnel

Our continued success depends in part upon the services of our key managerial, financial and technical personnel. The loss of key personnel, or our inability to attract, assimilate and retain qualified personnel, could result in the loss of customers,

27

inhibit our ability to operate and grow our business and otherwise have a material adverse effect on our business and results of operations. We have previously had to, and may in the future have to, impose salary reductions on employees during economic downturns in an effort to maintain our financial position. On several occasions in recent years executives and other employees have received limited or no annual bonuses due to our financial performance relative to the performance parameters in our annual bonus plans. These events may have an adverse effect on employee loyalty and may make it more difficult for us to attract and retain key personnel. Competition for qualified personnel in the industries and locations in which we compete for talent is intense, and we may not be successful in attracting and retaining qualified personnel. We may incur significant costs in our efforts to recruit and retain key personnel, which could affect our financial position and results of operations.

Risks Related to Technology

Markets Characterized by Rapid Technological Change

The markets for our products are characterized by rapid technological change and innovation, frequent new product introductions, changes in customer requirements and evolving industry standards. Our future performance will depend on the successful development, introduction and market acceptance of new and enhanced products that address technological changes and the requirements of current and potential customers. The development of new, technologically advanced products is a complex and uncertain process, requiring high levels of innovation and highly skilled engineering and development personnel, as well as the accurate anticipation of technological and market trends. We cannot assure you that we will be able to identify, develop, manufacture, market or support new or enhanced products successfully, if at all, or on a timely basis. The introduction by us or by our competitors of new or enhanced products, or alternative technologies, may cause our customers to defer, change or cancel orders for our existing products or cease purchasing our products altogether. Further, we cannot assure that our new products will gain timely market acceptance or that we will be able to respond effectively to product announcements by competitors, technology changes or emerging industry standards. If we are unable to develop new or enhanced products to address product or technology changes or new industry standards on a timely basis or at all, or if our new or enhanced products are not accepted by the market, or if our customers adopt alternative technologies, our business, financial condition and results of operations may be adversely affected.

Need to Invest in Research and Development

Our industry is characterized by the need for continued investment in research and development. Because of intense competition in the industries in which we compete, if we were to fail to invest sufficiently in research and development, our products could become less attractive to our current and potential customers or obsolete, and our business and financial condition could be materially and adversely affected. As a result of our need to maintain our spending levels in this area, our operating results could be materially harmed if our net sales decline. In addition, as a result of our emphasis on research and development and technological innovation, our operating costs may increase in the future, and research and development expenses may increase as a percentage of total operating expenses and as a percentage of net sales.

Need to Broaden our Marketing and Channel Capability

The laser microfabrication industry is comprised of broad set of markets and applications and represents significant opportunities for growth. In order to access these opportunities; we need to broaden our approach from customer centric to market based. This will require the hiring, development, and application of new marketing capability and channel access. Our ability to successfully access and compete in these broader markets will be partially dependent on our development of these new skills and capabilities. Our inability to do so would harm our business and adversely affect our revenues and profitability.

Products are Highly Complex

Our products are highly complex, and our extensive product development, manufacturing and testing processes may not be adequate to detect all defects, errors, failures and quality issues that could impact customer satisfaction or result in claims against us. As a result, we may have to replace certain components or provide remediation in response to the discovery of defects in products after they are shipped. The occurrence of any defects, errors, failures or quality issues could result in cancellation of orders, product returns, diversion of our resources, legal actions by our customers and other losses to us or to our customers. These occurrences could also result in the loss of, or delay in, market acceptance of our products, loss of sales and increased expenses and warranty costs, which would harm our business and adversely affect our revenues and profitability.

Risks Related to Legal Matters

Protection of Proprietary Rights – Generally

28

Our success depends significantly upon the protection of our proprietary rights. We attempt to protect our proprietary rights through patents, copyrights, trademarks, maintenance of trade secrets and other measures, including entering into confidentiality agreements. We incur substantial costs to obtain and maintain patents and to defend our intellectual property rights. We rely upon the laws of the United States and foreign countries where we develop, manufacture or sell our products to protect our proprietary rights. We may not be successful in protecting these proprietary rights, these rights may not provide the competitive advantages that we expect, or other parties may challenge, invalidate or circumvent these rights.

Protection of Proprietary Rights – Foreign Jurisdictions

Our efforts to protect our intellectual property may be less effective in some foreign countries where intellectual property rights are not as well protected as in the United States. Many United States companies have encountered substantial problems in protecting their proprietary rights against infringement in foreign countries. If we fail to adequately protect our intellectual property in these countries, it could be easier for our competitors to sell competing products in foreign countries, which could result in reduced sales and gross margins.

Intellectual Property Infringement Claims

Several of our competitors hold patents covering a variety of technologies, applications and methods of use similar to some of those used in our products. While we attempt in our designs to avoid patent infringement, from time to time we and our customers have received correspondence from our competitors claiming that some of our products, as used by our customers, may be infringing one or more of these patents. Competitors or others have in the past and may in the future assert infringement claims against our customers or us with respect to current or future products or uses, and these assertions may result in costly litigation or require us to obtain a license to use intellectual property rights of others. If claims of infringement are asserted against our customers, those customers may seek indemnification from us for damages or expenses they incur.

If we become subject to infringement claims, we will evaluate our position and consider the available alternatives, which may include seeking licenses to use the technology in question or defending our position. These licenses, however, may not be available on satisfactory terms or at all. If we are not able to negotiate the necessary licenses on commercially reasonable terms or successfully defend our position, our financial condition and results of operations could be materially and adversely affected.

We also defend our patent and intellectual property portfolio. We initiated litigation in 2014 against Humo Laboratory, LTD. in Japan and against Eo Technics Co., Ltd., in South Korea in May 2014 for infringement of key patents. There is no assurance that this litigation will be successful, and we may incur significant legal fees to prosecute these claims.

Tax Audits and Changes in Tax Law

We are periodically under audit by United States and foreign tax authorities and may have exposure to additional tax liabilities as a result. Significant judgment is required in determining our provision for income and other tax liabilities. Although we believe our tax estimates are reasonable, the final outcome of tax audits and the impact of changes in tax laws or the interpretation of tax laws could result in material differences from what is reflected in historical income tax accruals. If additional taxes are assessed as a result of an examination, a material effect on our financial results, tax positions or cash flows could occur in the period or periods in which the determination is made.

We currently benefit from a tax incentive program in Singapore pursuant to which we pay no Singapore income tax with respect to our manufacturing income. The incentive commenced on July 1, 2006 and will continue through June 30, 2016 assuming we are able to satisfy applicable requirements. The Company has failed to meet certain of the associated requirements in the past, however has obtained a waiver for certain periods. There is no assurance we will be able to satisfy these requirements and failure to meet such requirements may lead to reduction in future or past tax benefits. The Company believes that it is more likely than not the Company will continue to receive the associated tax incentives and there is no indication that past benefits received would be rescinded.

Legal Proceedings

From time to time we are subject to various legal proceedings, including breach of contract claims and claims that involve possible infringement of patent or other intellectual property rights of third parties or by third parties. It is inherently difficult to assess the outcome of litigation matters, and there can be no assurance that we will prevail in any litigation. Any litigation could result in substantial cost and diversion of management’s attention, which by itself could have a material adverse effect on our financial condition and results of operations. Further, adverse determinations in such litigation could result in loss of our property rights, subject us to significant liabilities, require us to seek licenses from others or prevent us from manufacturing or selling our products, any of which could materially adversely affect our business, financial condition, results of operations or cash flows.

29

Provisions Restricting Our Acquisition

Our articles of incorporation and bylaws contain provisions that could make it harder for a third party to acquire us without the consent of our Board of Directors. In addition, the Oregon Control Share Act and the Oregon Business Combination Act limit the ability of parties who acquire a significant amount of voting stock to exercise control over us. These provisions may have the effect of lengthening the time required for a person to acquire control of us through a proxy contest or the election of a majority of our Board of Directors, may deter efforts to obtain control of us and may make it more difficult for a third party to acquire us without negotiation. These provisions may apply even if the offer may be considered beneficial by our shareholders.

Risks Related to Financial Matters

Liquidity

We may require greater working capital to operate than similar size businesses in many other industries. At September 26, 2015, we had working capital of $122.4 million, including $60.2 million in cash and short-term investments. Our operating cash flows were negative for most quarters from September 2013 through March 2015. In the quarter ended September 26, 2015 we had positive operating cash flows of $2.2 million. If revenues were to grow, we would expect increased working capital needs for receivables and inventory. While we have a credit facility in place, the level of availability and cost are based on maintaining certain levels of qualified receivables and domestic cash. As a result, if either of these balances decreases sufficiently, our ability to access the facility may be limited or costs may be higher. In addition, if we fail to meet the covenants in our credit facility, including the tangible net worth covenant, the facility may not be available to us. If we were to require additional financing, there is no assurance it would be available on terms that are acceptable to us or at all. In addition, if we were to obtain financing by selling stock or convertible securities, the ownership of existing shareholders would be diluted. Our ability to obtain financing by selling stock or convertible securities could be negatively affected by the fact that we are currently ineligible to use a Form S-3 Registration Statement. If we were to require additional financing and were unable to do so on acceptable terms or at all, our business and our ability to continue operations could be materially and adversely affected.

Unfavorable Currency Exchange Rate Fluctuations

Currency exchange rate fluctuations could have an adverse effect on our sales and results of operations and we could experience losses with respect to forward exchange contracts into which we may enter. Unfavorable currency fluctuations could require us to increase prices to foreign customers, which could result in lower net sales by us to those customers. Alternatively, if we do not adjust the prices for our products in response to unfavorable currency fluctuations, our results of operations could be materially and adversely affected. In addition, some of our foreign sales are denominated in the currency of the country in which these products are sold and the currency we receive in payment for such sales could be less valuable at the time of receipt as a result of exchange rate fluctuations. From time to time, we enter into forward exchange contracts to hedge the value of accounts receivable primarily denominated in euros and other currencies. However, we cannot be certain that our efforts will be adequate to protect us against significant currency fluctuations or that such efforts will not expose us to additional exchange rate risks, which could adversely affect our results of operations.

Fluctuations in Effective Tax Rate

As a global company, we are subject to taxation in the United States and numerous foreign jurisdictions. Our effective tax rate is subject to fluctuation from one period to the next because the income tax rates for each year are a function of many factors, including: (a) taxable income levels and the effects of a mix of profits (losses) earned by ESI and our subsidiaries in numerous tax jurisdictions with a broad range of income tax rates; (b) our ability to utilize deferred tax assets; (c) taxes, refunds, interest or penalties resulting from tax audits; (d) the magnitude of various credits and deductions as a percentage of total taxable income; (e) the ability to maintain our Pioneer Status in Singapore; and (f) changes in tax laws or the interpretation of such tax laws. In addition, we currently have a valuation allowance against domestic tax assets as a result of historic losses recorded in the United States. Changes in the mix of these items may cause our effective tax rate to fluctuate between periods, which could have a material adverse effect on our financial position and results of operations.

Impairment of Goodwill, Intangible and Long-Lived Assets

We held a net total of $8.2 million in acquired intangible assets and $7.4 million in goodwill at September 26, 2015. We review our acquired intangible assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. In the fourth quarter of 2015 we realigned our products into two segments as a result of changes in our go-to-market strategies, common customer characteristics, and information utilized to manage our business. This reorganization required the Company to reassign its reported goodwill to the new reporting units based on the relative fair value of the respective reporting units.

30

We performed a review of our acquired definite-lived intangible assets in the fourth quarter of 2015, including a review for impairment based on certain triggering events and no significant impairments of intangible assets were identified.

The carrying value of goodwill by reporting unit prior to March 28, 2015 was approximately $7.4 million for Topwin, $6.3 million for Component Processing and $1.6 million for Micromachining. We performed our annual goodwill impairment analysis based on the carrying value of the reorganized reporting units. Carrying value was determined based on the Company's allocation of assets and liabilities to the reporting units using reasonable assumptions. We impaired $7.9 million of goodwill as of March 28, 2015, based on our analysis at the reporting unit level, which represented the goodwill associated with Component Processing and Micromachining. We will test for impairment of goodwill at the reporting unit level at least annually or between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value below the carrying value of the reporting unit. Should the performance of our Topwin reporting unit not meet our expectations, further impairment to goodwill may be triggered.

In addition, certain of our long-lived assets such as machinery and equipment may experience impairment in their value as a result of such events as the introduction of new products, changes in technology or changes in customer demand patterns. We depreciate our machinery and equipment at levels we believe are adequate; however, there can be no assurance that there will not be a future impairment that may have a material impact on our business, financial condition and results of operations.

Stock Price Volatility

The market price of our common stock has fluctuated widely. During the second quarter of 2016, our stock price fluctuated between a high of $5.28 per share and a low of $4.21 per share, and subsequent to the end of the fiscal quarter and prior to October 30, 2015 has been as low as $4.53. Consequently, the current market price of our common stock may not be indicative of future market prices, and we may be unable to sustain or increase the value of an investment in our common stock. Factors affecting our stock price, many of which are outside of our control, may include:

• variations in operating results from quarter to quarter;

• changes in earnings estimates by analysts or our failure to meet analysts’ expectations;

• changes in the market price per share of our public company customers;

• market conditions in the consumer electronics, semiconductor and other industries into which we sell products;

• general economic conditions;

• political changes, hostilities or natural disasters;

• low trading volume of our common stock;

• change in our dividend policy;

• the number of analysts covering our common stock;

• being added or removed from market indices;

• policies of institutional investors restricting or prohibiting investments in stock with a market price below certain thresholds;

• stock price volatility based on one or a few investors buying or selling a large number of shares over days or weeks, due to relatively low volumes of trading in our stock; and

• the number of firms making a market in our common stock.

In addition, the stock market has experienced significant price and volume fluctuations in recent years. These fluctuations have particularly affected the market prices of the securities of high-technology companies like ours. These market fluctuations could adversely affect the market price of our common stock.

Impairment of Investments

Our investment portfolio is primarily comprised of commercial paper, debt securities issued by U.S. governmental agencies and municipal debt securities. These investments are intended to be highly liquid and low risk. If the markets for these securities were to deteriorate for any reason, including as a result of a downgrade in the credit rating of U.S. government securities, the liquidity and value of these investments could be negatively affected, which could result in impairment charges. Any such impairment charges may have a material impact on our financial condition and results of operations.

If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results or prevent fraud and our stock price may be adversely affected.

Effective internal controls are necessary for us to provide reliable financial reports and effectively prevent fraud. If we cannot provide reliable financial reports or prevent fraud, our operating results could be harmed.

In connection with our 2015 audit we identified material weaknesses in our internal control over financial reporting related to the accounting and disclosure of complex, judgmental accounting matters and non-routine transactions. The matters

31

involving internal controls and procedures that our management considered to be material weaknesses included the risk assessment and certain process and review level controls associated with complex and non-routine transactions affecting goodwill, disclosures related to the Topwin acquisition, disclosures related to operating segments, presentation of service revenue and associated cost of sales on the statements of operations.

The Company is in the process of identifying and implementing certain changes in our internal controls to address the material weaknesses. Specifically, the Company is documenting, implementing, and assessing necessary changes in the risk assessment process and in the design of the controls and identifying additional procedures and expertise required to ensure effective management and technical review of significant, complex, and non-routine transactions.

Management believes that it will identify and implement additional controls that will remediate the material weaknesses discussed above. However, no assurance can be given that these changes will remediate the material weaknesses until such time that the controls have operated for a sufficient period of time and their operating effectiveness has been tested.

The requirements of Section 404 of the Sarbanes-Oxley Act are ongoing and also apply to future years. We expect that our internal control over financial reporting will continue to evolve as our business develops. Although we are committed to continue to improve our internal control processes and we will continue to diligently and vigorously review our internal control over financial reporting in order to ensure compliance with the Section 404 requirements, any control system, regardless of how well designed, operated and evaluated, can provide only reasonable, not absolute, assurance that its objectives will be met. Therefore, we cannot be certain that in the future additional material weaknesses or significant deficiencies will not exist or otherwise be discovered. If our efforts to remediate the weaknesses identified are not successful or if other deficiencies occur, these weaknesses or deficiencies could result in misstatements of our results of operations, additional restatements of our consolidated financial statements, a decline in our stock price and investor confidence, or other material effects on our business, reputation, results of operations, financial condition or liquidity.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In June 2014, the FASB issued ASU No. 2014-12, "Compensation - Stock Compensation (Topic 718)." ASU No. 2014-12 addresses accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. ASU 2014-12 indicates that, in such situations, the performance target should be treated as a performance condition and, accordingly, the performance target should not be reflected in estimating the grant-date fair value of the award. Instead, compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. We do not expect the adoption of ASU 2014-12 to have a material effect on our financial position, results of operations or cash flows.

In April 2015, the FASB issued ASU 2015-05, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40).” ASU 2015-05 provides guidance regarding the accounting for a customer's fees paid in a cloud computing arrangement, specifically about whether a cloud computing arrangement includes a software license, and if so, how to account for the software license. ASU 2015-05 is effective for public companies' annual periods, including interim periods, beginning after December 15, 2015. Early adoption is permitted. We do not expect the adoption of ASU 2015-05 to have a material effect on our financial position, results of operations or cash flows.

In July 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-11, “Simplifying the Measurement of Inventory (Topic 330).” ASU 2015-11 simplifies the accounting for the valuation of all inventory not accounted for using the last-in, first-out (“LIFO”) method by prescribing inventory be valued at the lower of cost and net realizable value. ASU 2015-11 is effective for public companies' annual periods, including interim periods within those fiscal years, beginning after December 15, 2016 on a prospective basis. Early adoption is permitted. We do not expect the adoption of ASU 2015-11 to have a material effect on our financial position, results of operations or cash flows.

In August 2015, the FASB issued ASU No. 2015-14, which defers the effective date of ASU No. 2014-09 "Revenue from Contracts with Customers" one year to interim and annual reporting periods beginning after December 15, 2017. This guidance may be adopted retrospectively or under a modified retrospective method where the cumulative effect is recognized at the date of initial application. The Company is currently evaluating the impact of adopting this guidance on its Consolidated Financial Statements and disclosures included within Notes to Consolidated Financial Statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

The Company

Basis of Presentation

These unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted in these interim statements. Accordingly, these condensed consolidated financial statements are to be read in conjunction with the financial statements and notes included in the Company's Annual Report on Form 10-K for its fiscal year ended March 28, 2015. These interim statements include all adjustments (consisting of only normal recurring adjustments and accruals) necessary for a fair presentation of results for the interim periods presented. The results for interim periods are not necessarily indicative of the results of operations for the entire year.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of commitments and contingencies at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results may differ from those estimates.

Management believes that the estimates used are reasonable. Significant estimates made by management include: revenue recognition; inventory valuation; product warranty reserves; allowance for doubtful accounts; accrued restructuring costs; share-based compensation; income taxes including the valuation of deferred tax assets; fair value measurements; valuation of cost method equity investments; valuation of long-lived assets; valuation of goodwill; and valuation of acquired technology.

There have been no significant changes to the Company's significant accounting policies from those presented in Note 2 “Summary of Significant Accounting Policies” to the consolidated financial statements included in the Company's Annual Report on Form 10-K for its fiscal year ended March 28, 2015. All references to years or quarters relate to fiscal years or fiscal quarters unless otherwise noted.

In the first quarter of 2016, certain prior period amounts were revised to conform to current year presentation. Please see Note 7 "Trade Accounts Receivable" and Note 10 "Accrued Current Liabilities & Other Liabilities".

16. Restructuring and Cost Management Plans

In March 2015, as a part of the plan to streamline its manufacturing and development activities, the Company initiated a restructuring plan to close the assembly plant and development center located in Chelmsford, Massachusetts. The estimated completion date of the plan is the end of fiscal 2016. See the Company's Form 10-K for the year ended March 28, 2015 for additional information related to restructuring and cost management plans.

Net restructuring costs of $0.7 million in the first two quarters of 2016 included severance and wind-up costs. These costs relate to the restructuring plan described above and our previously disclosed action to close our Beijing facility. At September 26, 2015 and March 28, 2015, the amount of unpaid restructuring costs included in accrued liabilities was $1.6 million and $2.0 million, respectively.

The following table presents the amounts related to restructuring costs payable (in thousands):

13. Commitments & Contingencies

On March 20, 2015, the Company entered into a loan and security agreement ("Loan Agreement") with Silicon Valley Bank, as lender. The Loan Agreement provides for a senior secured asset-based revolving credit facility (the “Credit Facility”) with up to $30 million available on a revolving basis, including a $15 million sublimit for letters of credit. The credit agreement expires March 20, 2018. At September 26, 2015, we had no revolving loans or letters of credit outstanding under our Credit Facility, we were in compliance with all covenants, and were not in default under the Loan Agreement. The commitment fee on the amount of unused credit was 0.3 percent.

We mitigate credit risk by transacting with highly rated counterparties for foreign exchange contracts, letters of credit and other transactions where counterparty risk is a factor. We have evaluated the non-performance risks associated with our lenders and other parties and believe them to be insignificant. From time to time we may be party to litigation arising in the normal course of business. Currently we are not party to any litigation we believe would have a material adverse effect on our financial position, results of operations, or cash flows.

Business Acquisitions

Fiscal 2015

On January 15, 2015, the Company acquired all of the outstanding shares of Wuhan Topwin Optoelectronics Technology Co., Ltd. (Topwin), a Chinese manufacturer of laser-based systems and as of March 28, 2015 the company performed a preliminary determination and allocation of purchase price to the identifiable acquired assets and liabilities. In the first quarter of 2016, the Company finalized the determination of purchase price, including the valuation of total consideration and the related contractual adjustments to working capital, and valuation of acquired assets and assumed liabilities. Analysis supporting the purchase price allocation included a valuation of assets and liabilities as of the closing date, an analysis of intangible assets and a detailed review of the opening balance sheet to determine other significant adjustments required to recognize assets and liabilities at fair value. Consideration was comprised of $7.6 million in cash and 748,944 shares of ESI common stock issuable over a three year period, valued at approximately $2.9 million as of the acquisition date. Of the $2.9 million in equity, one-half, or 374,472 shares, is contingent-based consideration and one-half, or 374,472 shares, is non-contingent and will be issued over a three year period beginning June 30, 2015. The contingent consideration is based on future performance of Topwin, as evaluated against targets for net income for each year over a three year period. One-third of the contingent shares will be issued after each year if the target is met for that year; however failing to meet stated targets will result in none of the contingent shares being issued for that year. As of the acquisition date, the fair value of the contingent consideration was estimated to be $0.4 million and of the 374,472 shares of non-contingent consideration was estimated to be $2.5 million. The fair value of the non-contingent and contingent shares was determined based on the estimated share price as of the issuance date derived through Monte Carlo simulation, discounted back to the acquisition date. The value of the contingent shares included consideration of the estimated probability of attainment of the net income targets. Additionally, the Company will issue, on the same terms described above, approximately 513,328 shares valued at $2.0 million, which, together with cash amounts of $0.2 million, is treated as compensation to a Principal in the Company who was also a former shareholder of Topwin. Compensation expense will be recognized over the Principal's term of employment or related service period required by the purchase agreement through December 31, 2017. In the first two quarters of fiscal 2016, we have recognized approximately $0.5 million in compensation expense related to this agreement, comprised primarily of share-based compensation.

The total purchase price of approximately $10.5 million, net of cash acquired, was allocated to the underlying assets acquired and liabilities assumed based on their fair values, as shown in the following table:

(In thousands)
Accounts receivable	$	454
Inventory	544
Prepaid expense and other current assets	295
Property, plant and equipment	23
Acquired intangibles	3,618
Goodwill	7,445
Accounts payable and other accrued liabilities	(1,859		)
Total purchase price, net of cash acquired	$	10,520

The acquisition is expected to enable the Company to gain entry into the low total-cost-of-ownership solutions market in China and the goodwill of approximately $7.4 million recognized as a result of the acquisition was assigned to the Topwin reporting unit. The premium paid over the fair value of the individual assets acquired and liabilities assumed reflects the Company’s view that this acquisition was the result of a competitive bid process and has provided the Company with innovative design and manufacturing capabilities for laser-based manufacturing solutions across a variety of complementary applications, together with direct access to local China market, supply chain and opto-electronics knowledge center. None of the goodwill is expected to be deductible for tax purposes.

As a result of the acquisition, the Company recorded approximately $4.9 million of identifiable assets, including $3.6 million of identifiable intangible assets, and $1.9 million of identifiable liabilities. The acquired intangible assets consist primarily of $3.5 million of developed technology and will be amortized over their useful lives, which range from one to ten years.

In the first two quarters of 2016, the Company incurred approximately $0.2 million in acquisition-related costs. In 2015, the Company incurred approximately $0.8 million in acquisition-related costs which were included in Selling, general and administrative expenses in the Consolidated Statements of Operations. The operating results of this acquisition are included in the Company’s results of operations since the date of acquisition. Pro forma financial information has not been provided for the acquisition of Topwin as it was not material to the Company’s operations and overall financial position.

Fair Value Measurements

Financial Assets Measured at Fair Value

ASC Topic 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include the following:

• Level 1, defined as observable inputs such as quoted prices in active markets for identical assets or liabilities;

• Level 2, defined as inputs that are observable either directly or indirectly such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and other inputs that can be corroborated by observable market data; and

• Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The Company’s fair value hierarchy for its financial assets measured at fair value on a recurring basis as of September 26, 2015 and March 28, 2015 was as follows (in thousands):

Deferred Revenue

Generally, revenue is recognized upon fulfillment of acceptance criteria at the Company's factory and transfer of risk and title. Revenue is deferred whenever title transfer is pending, risk has not transferred, and/or acceptance criteria have not yet been fulfilled. Deferred revenue occurrences include sales to Japanese customers, shipments of substantially new products and shipments with custom specifications and acceptance criteria. In sales involving multiple element arrangements, the relative selling price of any undelivered elements, including installation services, is deferred until the elements are delivered and acceptance criteria are met. Revenue related to maintenance and service contracts is deferred and recognized ratably over the duration of the contracts.

The following is a reconciliation of the changes in deferred revenue:

Segment Reporting [Abstract]

Product and Geographic Information

and Geographic Information

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is our Chief Executive Officer. Prior to the fourth quarter of 2015, we operated in one segment, high-technology manufacturing equipment, which was comprised of products that were classified in three groups: interconnect and micromachining, semiconductor and component. As a result of changes in our go-to-market strategies, common customer characteristics, and information utilized to manage our business, we realigned our products into two segments. Since the fourth quarter 2015 the Company has operated in two segments, Component Processing and Micromachining.

Net sales by segment were as follows:

Share-Based Compensation

Share-Based Compensation

The Company recognizes expense related to the fair value of its share-based compensation awards using the Black-Scholes model to estimate the fair value of awards on the date of grant, except for unvested restricted stock unit awards which are valued at the fair value of the Company's stock on the date of award. The Company recognizes compensation expense for all share-based compensation awards on a straight-line basis over the requisite service period of the award.

Stock-settled stock appreciation rights (SARs) grant the right to receive shares of the Company's stock equivalent to the increase in stock value of a specified number of shares over a specified period of time, divided by the stock price at the time of exercise. Similar to options, SARs are measured at the fair value of the award on the grant date and the expense is recognized on a straight-line basis over the requisite service period of the award.

The Company granted a total of 703,700 restricted stock units (RSUs), 467,000 SARs, and zero stock options during the first two quarters of 2016. The Company granted 513,700 RSUs and 260,000 SARs, and zero stock options during the first two quarters of 2015.

Share-based compensation expense was included in the Company’s Condensed Consolidated Statements of Operations as follows:

	Fiscal quarter ended				Two fiscal quarters ended
(In thousands)	Sep 26, 2015		Sep 27, 2014		Sep 26, 2015		Sep 27, 2014

Total share-based compensation expense	$	1,066	$	1,033	$	2,129	$	2,363

No share-based compensation costs were capitalized in the first two quarters of 2016. As of September 26, 2015, the Company had $9.1 million of total unrecognized share-based compensation costs, net of estimated forfeitures, which are expected to be recognized over a weighted average period of 2.2 years. The amounts shown in the table above for the fiscal quarter ended September 26, 2015 and two fiscal quarters ended September 26, 2015, do not include $173 thousand and $497 thousand, respectively, in expense related to acquisitions.

Earnings Per Share [Abstract]

(Loss) Earnings Per Share

Loss Per Share

The following is a reconciliation of weighted average shares outstanding used in the calculation of basic and diluted earnings per share:

	Fiscal quarter ended						Two fiscal quarters ended
(In thousands, except per share data)	Sep 26, 2015			Sep 27, 2014			Sep 26, 2015			Sep 27, 2014
Net loss	$	(3,260	)	$	(6,243	)	$	(9,624	)	$	(14,494	)
Weighted average shares used for basic earnings per share	31,384			30,552			31,280			30,452
Weighted average shares used for diluted earnings per share	31,384			30,552			31,280			30,452
Net loss per share:
Net loss — basic	$	(0.10	)	$	(0.20	)	$	(0.31	)	$	(0.48	)
Net loss — diluted	$	(0.10	)	$	(0.20	)	$	(0.31	)	$	(0.48	)

Awards of stock options, SARs and unvested RSUs representing an additional 3.7 million and 2.8 million shares of stock for the second quarter of 2016 and 2015, respectively, were not included in the calculation of diluted net earnings per share because their effect would have been antidilutive.
