1. Basis of Presentation

Novanta Inc. and its subsidiaries (collectively referred to as the “Company”, “we”, “us”, “our”) is a global supplier of core technology solutions that give healthcare and advanced industrial original equipment manufacturers (“OEMs”) a competitive advantage. We combine deep proprietary technology expertise and competencies in photonics, vision and precision motion with a proven ability to solve complex technical challenges. This enables Novanta to engineer core components and sub-systems that deliver extreme precision and performance, tailored to our customers' demanding applications.

The accompanying unaudited interim consolidated financial statements have been prepared in U.S. dollars and pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”), the instructions to Form 10-Q and the provisions of Regulation S-X pertaining to interim financial statements. Accordingly, certain information and footnote disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The interim consolidated financial statements and notes included in this report should be read in conjunction with the financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. In the opinion of management, these interim consolidated financial statements include all adjustments and accruals of a normal and recurring nature necessary to fairly state the results of the interim periods presented. The results for interim periods are not necessarily indicative of results to be expected for the full year or for any future periods.

Prior to January 10, 2017, the Company had an approximately 41% ownership interest in Laser Quantum Limited (“Laser Quantum”), a privately held company located in the United Kingdom, which was accounted for under the equity method of accounting. On January 10, 2017, the Company acquired an additional approximately 35% of the outstanding shares of Laser Quantum. As a result of this transaction, the Company’s ownership position in Laser Quantum increased from approximately 41% to approximately 76%. Since January 10, 2017, Laser Quantum has been consolidated in the Company’s consolidated financial statements.

The Company’s unaudited interim financial statements are prepared for each quarterly period ending on the Friday closest to the end of the calendar quarter, with the exception of the fourth quarter which always ends on December 31.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. The Company evaluates its estimates based on historical experience, current conditions and various other assumptions that it believes are reasonable under the circumstances. Estimates and assumptions are reviewed on an on-going basis and the effects of revisions are reflected in the period in which they are deemed to be necessary. Actual results could differ significantly from those estimates.

Recent Accounting Pronouncements

Presentation of Net Periodic Pension Cost

In March 2017, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2017-07, “Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,” which requires employers that offer or maintain defined benefit plans to disaggregate the service component from the other components of net benefit cost and provides guidance on the presentation of the service component and the other components of net benefit cost in the statement of operations. The new standard is effective for public companies for annual periods beginning after December 15, 2017. The Company expects to adopt the new standard in the first quarter of 2018 and expects to report its net periodic pension cost related to its frozen U.K. pension plan in Other income/(expense) in the consolidated statement of operations upon adoption.

Goodwill Impairment

NOVANTA INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

AS OF MARCH 31, 2017

(Unaudited)

In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which simplifies the accounting for goodwill impairment. The amendment in ASU 2017-04 removes Step-two of the goodwill impairment test, which requires a hypothetical purchase price allocation. ASU 2017-04 will become effective prospectively for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption p ermitted. The Company is currently evaluating the impact of the new standard on our consolidated financial statements.

Statement of Cash Flows Classification of Certain Cash Receipts and Cash Payments

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” The standard further clarifies the classification in the cash flow statement of the following items: (i) debt prepayment or debt extinguishment costs; (ii) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (iii) contingent consideration payments made after a business combination; (iv) proceeds from the settlement of insurance claims; (v) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (vi) distributions received from equity method investees; (vii) beneficial interests in securitization transactions; and (viii) separately identifiable cash flows and application of the predominance principle. ASU 2016-15 will become effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. ASU 2016-15 should be applied using a retrospective transition method for each period presented. The Company adopted ASU 2016-15 during the first quarter of 2017. The adoption of ASU 2016-15 resulted in ($2.4) million of payments of contingent considerations being reported as cash used in financing activities on the Company’s consolidated statements of cash flows for the three months ended March 31, 2017.

Leases

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which provides comprehensive lease accounting guidance. The standard requires entities to recognize lease assets and liabilities on the balance sheet and to disclose key information about leasing arrangements. ASU 2016-02 will become effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of the new standard on our consolidated financial statements.

Revenue from Contracts with Customers

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which provides guidance for revenue recognition. ASU 2014-09 supersedes the revenue recognition requirements in ASC 605, “Revenue Recognition” (Topic 605), and requires entities to recognize revenue in a way that depicts the transfer of goods or services to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 will be effective for annual and interim reporting periods beginning after December 15, 2016. Early adoption is not permitted. Upon adoption, an entity may apply the new guidance either retrospectively to each prior reporting period presented or retrospectively only to customer contracts not yet completed as of the date of adoption with the cumulative effect of initially applying the standard recognized in beginning retained earnings at the date of the initial application. In August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers – Deferral of the Effective Date,” which defers the effective date of ASU 2014-09 by one year, with the option of early adoption as of the original effective date. The amendment in ASU 2015-14 will result in ASU 2014-09 being effective for annual and interim reporting periods beginning after December 15, 2017. The Company has identified various revenue streams that could be impacted by Topic 606 and has started to review individual customer contracts related to these various revenue streams to determine if any material differences exist between Topic 605 and Topic 606.  The Company will adopt Topic 606 in the first quarter of 2018 and has preliminarily concluded that it will use the modified retrospective method upon adoption.

2. Business Combinations

ThingMagic

On January 10, 2017, the Company acquired from Trimble Inc. certain assets and liabilities that constituted the business of ThingMagic, a Woburn, Massachusetts-based provider of ultra-high frequency (“UHF”) radio frequency identification (“RFID”) modules and finished RFID readers to OEMs in the medical and advanced industrial markets, for a total purchase price of $19.2 million, subject to customary working capital adjustments. The acquisition was financed with cash on hand and a $12.0 million draw-down on our revolving credit facility. The Company expects that the addition of ThingMagic will broaden its portfolio of RFID

(Unaudited)

soluti ons, while providing the resources to address the growing need for improvements in workflow solutions, patient safety, anti-counterfeiting, and asset tracking in a medical environment. ThingMagic is included in the Company’s Vision reportable segment.

The acquisition of ThingMagic has been accounted for as a business combination. The allocation of the purchase price is based upon a valuation of assets and liabilities acquired. Assets acquired and liabilities assumed have been recorded at their estimated fair values as of the acquisition date. The fair values of intangible assets were based on valuations using an income approach, with estimates and assumptions provided by management of ThingMagic and the Company. The process for estimating the fair values of identifiable intangible assets requires the use of significant estimates and assumptions, including estimating future cash flows and developing appropriate discount rates. The excess of the purchase price over the tangible assets, identifiable intangible assets and assumed liabilities was recorded as goodwill. The Company’s estimates and assumptions in determining the estimated fair values of certain assets and liabilities are subject to change within the measurement period (up to one year from the acquisition date) as a result of additional information obtained with regards to facts and circumstances that existed as of the acquisition date. The purchase price allocation is preliminary as the Company is in the process of collecting additional information for the valuation of inventory and intangible assets.

Based upon a preliminary valuation, the total purchase price was allocated as follows (in thousands):

The fair value of intangible assets is comprised of the following (dollar amounts in thousands):

The purchase price allocation resulted in $7.3 million of identifiable intangible assets and $10.0 million of goodwill. As the ThingMagic acquisition is treated as an acquisition of assets for income tax purposes, the goodwill acquired is expected to be fully deductible. Intangible assets are being amortized over their weighted average useful lives primarily based upon the pattern in which anticipated economic benefits from such assets are expected to be realized. The goodwill recorded represents the anticipated incremental value of future cash flows potentially attributable to: (i) ThingMagic’s ability to grow its business with existing and new customers, including leveraging the Company’s customer base, (ii) cost synergies in combining the research and development capabilities from ThingMagic with the existing RFID capabilities within Novanta, and (iii) cost improvements due to the integration of ThingMagic operations into the Company’s existing infrastructure.

The operating results of ThingMagic were included in the Company’s results of operations beginning on January 10, 2017. ThingMagic contributed revenues of $1.9 million and a loss from continuing operations before income taxes of $0.3 million for the three months ended March 31, 2017. Operating loss from continuing operations before income taxes for the three months ended

NOVANTA INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

AS OF MARCH 31, 2017

(Unaudited)

March 31, 2017 included amortization of inventory fair value adjustments and amortization of purchased intangible assets of $0.6 million.

The pro forma financial information reflecting the operating results of ThingMagic, as if it had been acquired as of January 1, 2016, would not differ materially from the operating results of the Company as reported for the year ended December 31, 2016.

Laser Quantum Limited

On January 10, 2017, the Company acquired an additional approximately 35% of the outstanding shares of Laser Quantum, a Manchester, United Kingdom-based provider of solid state continuous wave lasers, femtosecond lasers, and optical light engines to OEMs in the medical market, for £25.5 million ($31.1 million) in cash consideration. The purchase price was financed with cash on hand and a $30.0 million draw-down on our revolving credit facility. By establishing control through a majority equity ownership, the Company expects to broaden its technology capability in photonics solutions for medical applications, particularly within the growing DNA sequencing market, while providing key enabling photonics-based technologies for instrumentation and life science applications such as biomedical imaging, cell sorting, and ophthalmology. Laser Quantum is included in the Company’s Photonics reportable segment.

As a result of this transaction, the Company’s ownership position in Laser Quantum increased from approximately 41% to approximately 76%. In connection with the purchase price allocation under the business combination rules, the Company recognized a nontaxable gain of $26.4 million in the consolidated statements of operations for the three months ended March 31, 2017. The gain represented the excess fair value of the Company’s previously-held equity interest in Laser Quantum over its carrying value.

The fair value of the approximately 41% equity interest previously held by the Company before the acquisition and the fair value of the approximately 24% noncontrolling interest (“NCI”) held by the remaining shareholders of Laser Quantum after the acquisition were determined using a combination of the discounted cash flow method (an income approach), the guideline public company method (a market approach), and the subject company transaction method (a market approach). The subject company transaction method was based on the purchase price paid by the Company for the acquisition of the additional approximately 35% of the outstanding shares, while giving consideration to the control and/or minority nature of the subject equity interests.

In addition, the Company and the remaining shareholders of Laser Quantum entered into a call and put option for the purchase and sale in 2020 of all remaining Laser Quantum shares held by the other shareholders, subject to certain conditions. The purchase price for the remaining shares will be based on a multiple of Laser Quantum’s EBITDA for the twelve months ending December 31, 2019, as defined in the call and put option agreement.

The acquisition of Laser Quantum has been accounted for as a business combination. The allocation of the purchase price is based upon a valuation of assets and liabilities acquired. Assets acquired and liabilities assumed have been recorded at their estimated fair values as of the acquisition date. The fair values of intangible assets were based on valuations using an income approach, with estimates and assumptions provided by management of Laser Quantum and the Company. The process for estimating the fair values of identifiable intangible assets requires the use of significant estimates and assumptions, including estimating future cash flows and developing appropriate discount rates. The excess of the purchase price over the tangible assets, identifiable intangible assets and assumed liabilities was recorded as goodwill. The Company’s estimates and assumptions in determining the estimated fair values of certain assets and liabilities are subject to change within the measurement period (up to one year from the acquisition date) as a result of additional information to be obtained with regards to facts and circumstances that existed as of the acquisition date. The purchase price allocation is preliminary as the Company is in the process of collecting additional information for the valuation of inventory, intangible assets, deferred tax liabilities, and unrecognized tax benefits.

Based upon a preliminary valuation, the total purchase price was allocated as follows (in thousands):

8

The fair value of intangible assets is comprised of the following (dollar amounts in thousands):

The purchase price allocation resulted in $39.0 million of identifiable intangible assets and $31.5 million of goodwill. As the Laser Quantum acquisition is an acquisition of outstanding common shares, none of the resulting goodwill is deductible for tax purposes. Intangible assets are being amortized over their weighted average useful lives primarily based upon the pattern in which anticipated economic benefits from such assets are expected to be realized. The goodwill recorded represents the anticipated incremental value of future cash flow potential attributable to: (i) Laser Quantum’s ability to grow its business with existing and new customers, including leveraging the Company’s broader customer base, and (ii) cost improvements due to expansion in scale.

The operating results of Laser Quantum were included in the Company’s results of operations beginning on January 10, 2017. Laser Quantum contributed revenues of $7.2 million and income from continuing operations before income taxes of $0.1 million for the three months ended March 31, 2017. Operating income from continuing operations before income taxes for the three months ended March 31, 2017 included $2.1 million expenses associated with the amortization of inventory fair value step-up and purchased intangible assets.

The pro forma information for all periods presented below includes the effects of business combination accounting resulting from the acquisition of Laser Quantum, including amortization of inventory fair value adjustments, amortization of intangible assets, interest expense on borrowings in connection with the acquisition, elimination of the gain from business acquisition and income from equity method investment, and the related tax effects as though the acquisition had been consummated as of January 1, 2016. The pro forma financial information is presented for comparative purposes only and is not necessarily indicative of the results of operations that actually would have been achieved if the acquisition had taken place on January 1, 2016.

3. Discontinued Operations and Divestitures

In July 2014, the Company completed the sale of certain assets and liabilities of its Scientific Lasers business for approximately $6.5 million in cash, net of working capital adjustments.  In accordance with the purchase and sale agreement, $1.5 million of the sales proceeds was held in escrow until January 2016. In January 2016, the $1.5 million escrow was released to the Company in full and is reported as cash flow from investing activities of discontinued operations.

4. Accumulated Other Comprehensive Income (Loss)

Changes in accumulated other comprehensive income (loss) was as follows (in thousands):

5. Earnings per Share

Basic earnings per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. For diluted earnings per common share, the denominator also includes the dilutive effect of outstanding restricted stock units, stock options and total shareholder return performance restricted stock units determined using the treasury stock method. Dilutive effects of contingently issuable shares are included in the weighted average dilutive share calculation using the

treasury stock method when the contingencies have been resolved. For periods in which net losses are generated, the dilutive potential common shares are excluded from the calculation of diluted earnings per share as the effect would be anti-dilutive.

The following table sets forth the computation of basic and diluted earnings per share (in thousands, except per share amounts):

Common Share Repurchases

During the three months ended March 31, 2017, the Company repurchased 14,000 shares in the open market for an aggregate purchase price of $0.4 million at an average price of $26.41 per share.

6. Fair Value Measurements

ASC 820, “Fair Value Measurements,” establishes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the third is considered unobservable:

The Company’s cash equivalents are investments in money market accounts, which represent the only asset the Company measures at fair value on a recurring basis. The Company determines the fair value of cash equivalents using a market approach based on quoted prices in active markets. The fair values of cash, accounts receivable, income taxes receivable, accounts payable, income taxes payable and accrued expenses and other current liabilities (excluding contingent considerations) approximate their carrying values because of their short-term nature.

Contingent consideration

On December 18, 2015, the Company acquired all assets and certain liabilities of Skyetek. Under the purchase and sale agreement for the Skyetek acquisition, the owners of Skyetek are eligible to receive contingent consideration based on the achievement of certain sales order commitment targets from October 2015 through June 2017. The undiscounted range of possible contingent consideration is zero to $0.3 million. If such targets are achieved, the contingent consideration will be payable in 2017. The Company recognized an estimated fair value of $0.2 million as part of the purchase price as of the acquisition date. Subsequent changes in the estimated fair value of this contingent liability will be recorded in the consolidated statement of operations in restructuring, acquisition and divestiture related costs until the liability is fully settled. There have been no changes to the fair value of the contingent consideration since the acquisition date.

On November 11, 2015, the Company acquired Lincoln Laser. Under the purchase and sale agreement for the Lincoln Laser acquisition, the shareholders of Lincoln Laser are eligible to receive contingent consideration based on the achievement of certain revenue targets for fiscal year 2016. The estimated fair value of the contingent consideration of $2.3 million was determined based on the Monte Carlo valuation method and was recorded as part of the purchase price as of the acquisition date. Based on Lincoln Laser’s fiscal year 2016 revenue results, the fair value of the contingent consideration for Lincoln Laser was adjusted to $1.4 million as of December 31, 2016. The Company paid $1.4 million as final settlement of the contingent consideration during the three months ended March 31, 2017.

On February 19, 2015, the Company acquired Applimotion. Under the purchase and sale agreement for the Applimotion acquisition, the former shareholders of Applimotion are eligible to receive contingent consideration based on the achievement of certain revenue targets for fiscal years 2015 to 2017. The undiscounted range of contingent considerations is zero to $4.0 million. If such targets are achieved, the contingent consideration will be payable in cash in two installments in 2017 and 2018, respectively. The estimated fair value of the contingent consideration of $1.0 million was determined based on the Monte Carlo valuation method and was recorded as part of the purchase price as of the acquisition date. Subsequent changes in the estimated fair value of this contingent liability are recorded in the consolidated statement of operations in restructuring, acquisition and divestiture related costs until the liability is fully settled. Under the Monte Carlo valuation method, the fair value of the contingent consideration for Applimotion was $3.6 million as of December 31, 2016. Based on Applimotion’s revenue performance for 2015 and 2016, the Company paid $1.2 million contingent consideration during the three months ended March 31, 2017. The estimated fair value of the remaining contingent consideration of $2.4 million is reported as a current liability in accrued expenses and other current liabilities on the consolidated balance sheet as of March 31, 2017. The second installment of the contingent consideration will be payable in the first quarter of 2018.

The following table summarizes the fair values of our financial assets and liabilities as of March 31, 2017 (in thousands):

7. Goodwill and Intangible Assets

Goodwill

Goodwill is recorded when the consideration for a business combination exceeds the fair value of net tangible and identifiable intangible assets acquired. The Company tests its goodwill balances annually for impairment as of the beginning of the second quarter or more frequently if indicators are present or changes in circumstances suggest that impairment may exist. The Company performed its last annual goodwill impairment test at the beginning of the second quarter of 2016 and noted no impairment of goodwill. Implied fair value of all reporting units exceeded their carrying values by at least 20%.

The following table summarizes changes in goodwill during the three months ended March 31, 2017 (in thousands):

9. Debt

Debt consisted of the following (in thousands):

Senior Credit Facilities

On May 19, 2016, the Company entered into the second amended and restated credit agreement (the “Second Amended and Restated Credit Agreement”) with new and existing lenders for an aggregate credit facility of $300.0 million, consisting of a $75.0 million, 5-year term loan facility due in quarterly installments of $1.9 million beginning in July 2016 and a $225.0 million, 5-year revolving credit facility (collectively, the “Senior Credit Facilities”). The Senior Credit Facilities mature in May 2021. Quarterly installments due in the next twelve months under the term loan amount to $7.5 million and are classified as a current liability on the consolidated balance sheet. The increase in the amount outstanding under the Company’s revolving credit facility in the three months ended March 31, 2017 was related to additional borrowings to fund the Laser Quantum and ThingMagic acquisitions.

The Company is required to satisfy certain financial and non-financial covenants under the Second Amended and Restated Credit Agreement. The Company was in compliance with these covenants as of March 31, 2017.

Liens

The Company’s obligations under the Senior Credit Facilities are secured on a senior basis by a lien on substantially all of the assets of the Company and its material United States (“U.S.”) and United Kingdom (“U.K.”) subsidiaries and guaranteed by the Company and its material U.S. and U.K. subsidiaries. The Second Amended and Restated Credit Agreement also contains customary events of default.

Fair Value of Debt

As of March 31, 2017 and December 31, 2016, the outstanding balance of the Company’s debt approximated its fair value based on current rates available to the Company for debt of the same maturity.

10. Share-based Compensation

The table below summarizes share-based compensation expense recorded in income from continuing operations in the consolidated statements of operations (in thousands):

NOVANTA INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

AS OF MARCH 31, 2017

(Unaudited)

The expense recorded during each of the three-month periods ended March 31, 2017 and April 1, 2016, respectively, included $0.5 million related to deferred stock units granted to the members of the Company’s Board of Directors.

Service-based Restricted Stock Units and Deferred Stock Units

The Company’s restricted stock units (“RSUs”) have been issued with vesting periods of three, four, and five years and vest based solely on service conditions. Accordingly, the Company recognizes compensation expense on a straight-line basis over the requisite service period. The Company reduces the compensation expense by an estimated forfeiture rate which is based on anticipated forfeitures and actual experience.

Deferred stock units (“DSUs”) are granted solely to the members of the Company’s Board of Directors, and have been issued as fully vested and non-forfeitable awards upon grant. The compensation expense associated with the DSUs is recognized in full on the respective date of grant.

The table below summarizes activities relating to RSUs and DSUs issued and outstanding under the Company’s Amended and Restated 2010 Incentive Plan during the three months ended March 31, 2017:

The total fair value of RSUs and DSUs that vested during the three months ended March 31, 2017 was $4.7 million based on the market price of the underlying stock on the date of vesting.

Performance-based Awards

The Company granted two types of performance-based awards to certain members of the executive management team: non-GAAP EPS performance-based restricted stock units (“EPS-PSUs”) and relative total shareholder return performance-based restricted stock units (“TSR-PSUs”). Both types of performance-based restricted stock units generally cliff vest on the first day following the end of the three-year performance period.

The number of common shares to be issued upon settlement following vesting of the EPS-PSUs is determined based on the Company’s cumulative non-GAAP EPS over the three-year performance period against the target established by the Company’s Board of Directors at the time of grant and will be in the range of zero to 200% of the target number of shares. The Company recognizes the related compensation expense ratably over the performance period based on the number of shares that are deemed probable of vesting at the end of the three-year performance cycle. This probability assessment is performed quarterly and the cumulative effect of a change in the estimated compensation expense, if any, is recognized in the consolidated statement of operations in the period in which such determination is made.  

The number of shares to be issued upon settlement following vesting of the TSR-PSUs is determined based on the relative market performance of the Company’s common stock compared to the Russell 2000 Index over the three-year performance period using a payout formula established by the Company’s Board of Directors at the time of grant and will be in the range of zero to 200% of the target number of shares. The Company recognizes the related compensation expense based on the fair value of the TSR-PSUs, determined using the Monte-Carlo valuation model as of the date of grant, on a straight-line basis from the grant date to the end of the three-year performance period. Compensation expense will not be affected by the number of TSR-PSUs that will actually vest at the end of the three-year performance period.

AS OF MARCH 31, 2017

(Unaudited)

The table below summarizes the activities relating to the performance-based awards issued and outstanding under the Company’s Amended and Restated 2010 Incentive Plan during the three months ended March 31, 2017 :

The fair value of the TSR-PSUs at the date of grant was estimated using the Monte-Carlo valuation model with the following assumptions:

Stock Options

The fair value of stock options is estimated using the Black-Scholes valuation model. Key input assumptions include the expected option term, the expected volatility of the common stock over the expected term of the options, the risk-free interest rate, and the expected dividend yield. Compensation expense related to stock options is recognized in the consolidated statement of operations on a straight-line basis over the vesting period. No stock options were granted during the three months ended March 31, 2017.

11. Income Taxes

The Company determines its estimated annual effective tax rate at the end of each interim period based on full-year forecasted pre-tax income and facts known at that time. The estimated annual effective tax rate is applied to the year-to-date pre-tax income at the end of each interim period. The tax effect of significant unusual items is reflected in the period in which they occur. Since the Company is incorporated in Canada, it is required to use Canada’s statutory tax rate of 29.0% in the determination of the estimated annual effective tax rate.

The Company’s effective tax rate on income from continuing operations of 3.1% for the three months ended March 31, 2017 differs from the Canadian statutory tax rate of 29.0% primarily due to the mix of income earned in jurisdictions with varying tax rates, the impact associated with establishing control over Laser Quantum upon the acquisition of an additional 35% of Laser Quantum’s outstanding shares, losses in jurisdictions with a full valuation allowance, and other discrete items for the period.  The Company reported a nontaxable gain of $26.4 million on its previously-held Laser Quantum equity interest and wrote off $1.4 million of Laser Quantum related deferred tax liability, which had a combined 24.5% favorable impact on our effective tax rate for the three months ended March 31, 2017.

The Company’s effective tax rate on income from continuing operations of 14.5% for the three months ended April 1, 2016 differed from the Canadian statutory rate of 27.0% primarily due to the mix of income earned in jurisdictions with varying tax rates, losses in jurisdictions with a full valuation allowance, the Laser Quantum dividend distribution and the impact of other discrete items for the period. The Company received a tax free cash dividend of $2.3 million from Laser Quantum, which had an 18.9% favorable impact on our effective tax rate for the three months ended April 1, 2016.

2016 Restructuring

We substantially completed the 2016 restructuring program during the second quarter of 2016. As of March 31, 2017, the Company incurred cumulative costs related to this restructuring plan totaling $6.2 million.

2011 Restructuring

In November 2011, the Company announced a strategic initiative (“2011 restructuring”), which aimed to consolidate operations to reduce the Company’s cost structure and improve operational efficiency. As part of this initiative, the Company eliminated facilities through the consolidation of certain manufacturing, sales and distribution facilities and the exit of Semiconductor Systems and Laser Systems businesses. The Company substantially completed the 2011 restructuring program by the end of 2013. In March 2016, the Company sold its previously exited Laser Systems facility located in Orlando, Florida for cash at the net carrying value of $3.5 million.
