Summary of Significant Accounting Policies	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business ® ® ® 3D 3D Principles of Consolidation Revenue Recognition, Product Warranty and Extended Warranty Contracts Cash and Cash Equivalents Income Taxes Accounts Receivable and Related Allowance for Doubtful Accounts Inventories Service inventory is typically used to provide a temporary replacement product to a customer covered by a premium warranty when the customer’s unit requires service or repair and as training equipment. Service inventory is available for sale; however, management does not expect service inventory to be sold within 12 months and, as such, classifies this inventory as a long-term asset. Service inventory that we utilize for training or repairs which we deem as no longer available for sale is transferred to fixed assets at the lower of cost or net realizable value and depreciated over its remaining useful life, typically three years. We transferred $3.0 million of service inventory to “Property and Equipment” in 2015. Reserve for Excess and Obsolete Inventory— Property and Equipment Machinery, equipment and software 2 to 5 years Furniture and fixtures 3 to 10 years Leasehold improvements are amortized on a straight-line basis over the lesser of the life of the asset or the remaining term of the lease. Depreciation expense was $9,238, $6,171 and $5,825 in 2015, 2014 and 2013, respectively. Accelerated methods of depreciation are used for income tax purposes in contrast to book purposes, and as a result, appropriate provisions are made for the related deferred income taxes. Business Combinations Goodwill and Intangibles Each period, and for any of our reporting units, we can elect to perform a qualitative assessment to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. If we believe, as a result of our qualitative assessment, that it is not more likely than not that the fair value of a reporting unit containing goodwill is less than its carrying amount, then the first and second steps of the quantitative goodwill impairment test are unnecessary. If we elect to bypass the qualitative assessment option, or if the qualitative assessment was performed and resulted in the Company being unable to conclude that it is not more likely than not that the fair value of a reporting unit containing goodwill is greater than its carrying amount, we will perform the two-step quantitative goodwill impairment test. We perform the first step of the two-step quantitative goodwill impairment test by calculating the fair value of the reporting unit using a discounted cash flow method and market approach method, and then comparing the respective fair value with the carrying amount of the reporting unit. If the carrying amount of the reporting unit exceeds its fair value, we perform the second step of the quantitative goodwill impairment test to measure the amount of the impairment loss, if any. Management has concluded there was no goodwill impairment for the years ended December 31, 2015, 2014 and 2013. Other intangible assets principally include patents, existing product technology and customer relationships that arose in connection with our acquisitions. Other intangible assets are recorded at fair value at the date of acquisition and are amortized over their estimated useful lives of 3 to 20 years. As of December 31, 2015, there were no indefinite-lived intangible assets. Product technology and patents are recorded at cost. Amortization is computed using the straight-line method over the lives of the product technology and patents of 7 to 20 years. The remaining weighted-average amortization period for all our intangible assets is nine years. Long-Lived Assets Research and Development Reserve for Warranties Income Taxes We recognize tax benefits related to uncertain tax positions only if it is more likely than not that the tax position will be sustained upon examination by taxing authorities. For those positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. In the ordinary course of business, we are examined by various federal, state, and foreign tax authorities. We regularly assess the potential outcomes of these examinations and any future examinations for the current or prior years in determining the adequacy of our provision for income taxes. Earnings Per Share (EPS) Earnings Per Share Accounting for Stock-Based Compensation Stock Compensation Plans We measure and record compensation expense using the applicable accounting guidance for share-based payments related to stock options, restricted stock, and performance-based awards granted to our directors and employees. The fair value of stock options, including performance awards, without a market condition is estimated, at the date of grant, using the Black-Scholes option-pricing model. The fair value of restricted stock awards and stock options with a market condition is estimated, at the date of grant, using the Monte Carlo Simulation model. The Black-Scholes and Monte Carlo Simulation valuation models incorporate assumptions as to stock price volatility, the expected life of options or awards, a risk-free interest rate and dividend yield. In valuing our stock options, significant judgment is required in determining the expected volatility of our common stock and the expected life that individuals will hold their stock options prior to exercising. Expected volatility for stock options is based on the historical and implied volatility of our own common stock while the volatility for our restricted stock units with a market condition is based on the historical volatility of our own stock and the stock of companies within our defined peer group. The expected life of stock options is derived from the historical actual term of option grants and an estimate of future exercises during the remaining contractual period of the option. While volatility and estimated life are assumptions that do not bear the risk of change subsequent to the grant date of stock options, these assumptions may be difficult to measure as they represent future expectations based on historical experience. Further, our expected volatility and expected life may change in the future, which could substantially change the grant-date fair value of future awards of stock options and, ultimately, the expense we record. The fair value of restricted stock, including performance awards, without a market condition is estimated using the current market price of our common stock on the date of grant. Additionally, in calculating compensation expense for these awards, we are also required to estimate the extent to which awards will be forfeited prior to vesting. Many factors are considered when estimating expected forfeitures, including types of awards, employee class and historical experience. To the extent actual results or updated estimates of forfeiture differ from current estimates, such amounts are recorded as a cumulative adjustment to the previously recorded amounts. We expense stock-based compensation for stock options, restricted stock awards, and performance awards over the requisite service period. For awards with only a service condition, we expense stock-based compensation, adjusted for estimated forfeitures, using the straight-line method over the requisite service period for the entire award. For awards with both performance and service conditions, we expense the stock-based compensation, adjusted for estimated forfeitures, on a straight-line basis over the requisite service period for each separately vesting portion of the award, taking into account the probability that we will satisfy the performance conditions. Furthermore, we expense awards with a market condition over the three-year vesting period regardless of the value that the award recipients ultimately receive. Excess tax benefits are credited to common stock when the deduction reduces cash taxes payable. When we have tax deductions in excess of the compensation cost, they are classified as financing cash inflows in the Consolidated Statements of Cash Flows. Concentration of Credit Risk Estimates Impact of Recently Issued Accounting Standards In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory, which changes the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. ASU 2015-11 defines net realizable value as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The new guidance must be applied on a prospective basis and is effective for fiscal years beginning after December 15, 2015, and interim periods within those years, with early adoption permitted. We do not believe the implementation of this standard will have a material impact on our consolidated financial statements. In May 2014, the FASB issued an amendment to its accounting guidance related to revenue recognition. The amendment was the result of a joint project between the FASB and the International Accounting Standards Board (“IASB”) to clarify the principles for recognizing revenue and to develop common revenue standards for U.S. GAAP and International Financial Reporting Standards. To meet those objectives, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers: Topic 606 (“ASU 2014-09”). ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the FASB issued ASU 2015-14, Revenue from contracts with customers (Topic 606): Deferral of the Effective Date, deferring the effective date of ASU 2014-09 by one year. With this deferral, the new standard is effective for us on January 1, 2018. The standard permits the use of either the retrospective or cumulative effective transition method. We are evaluating the impact of adopting this standard on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting. Reclassifications Inventories

SHORT-TERM INVESTMENTS Short-term investments of $43.0 million and $65.0 million at December 31, 2015 and 2014, respectively, were comprised of six-month U.S. Treasury Bills that mature through April 14, 2016. The interest rate on the U.S. Treasury Bills is less than one percent. The investments are classified as held-to-maturity and recorded at cost plus accrued interest, which approximates fair value. The fair value of the U.S. Treasury Bills at December 31, 2015 and 2014 were classed as Level 1 as they are traded with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis.

We use several contract manufacturers and suppliers to provide manufacturing services for our products. In the normal course of business, to reduce manufacturing lead times and ensure adequate component availability, we enter into agreements with these manufacturers and suppliers to purchase sufficient inventory based on our forecast demand. At September 26, 2105, we had purchase commitments with suppliers for inventory that we no longer expected to utilize through the product lifecycle and for warranty commitments. Consequently, we recorded a $5.9 million write-down of excess inventory and a $2.0 million loss on purchase commitments in the third quarter of 2015. The aggregate of $7.9 million is included within the consolidated statement of cash flows for the year ended December 31, 2015 under the caption “Write-down of inventories”.

Goodwill

Goodwill	12 Months Ended

Goodwill	6. GOODWILL Our goodwill at December 31, 2015 and 2014 is related to our previous acquisitions. We evaluate each reporting unit’s fair value as compared to its carrying value on December 31 of each year or more frequently if events or changes in circumstances indicate that the carrying value may exceed the fair value. We first performed a qualitative assessment to determine whether it was necessary to perform the two-step goodwill impairment test. We concluded a quantitative goodwill impairment test, or step 1, was necessary. The fair value of the reporting units was measured using a discounted cash flow model incorporating discount rates commensurate with the risks involved for each reporting unit and a market approach. The key assumptions used in the discounted cash flow model include discount rates, growth rates, cash flow projections and terminal value rates. These rates are susceptible to change and require significant management judgment. The market approach relies on an analysis of publicly-traded companies similar to us and derives a range of revenue and profit multiples. The publicly-traded companies used in the market approach were selected based on our defined peer group. The resulting multiples were then applied to each reporting unit to determine fair value. Impairments to goodwill are charged against earnings in the period the impairment is identified. We have two reporting units for which goodwill was tested on December 31, 2015: the Americas Region, and the Europe/Africa Region, as shown in the table below. As of December 31, 2015 and 2014, we did not have any goodwill that was identified as impaired. The increase in goodwill in 2015 reflected the acquisitions completed in 2015, partially offset by changes in foreign exchange rates. The decrease in goodwill in 2014 related to changes in foreign exchange rates, partially offset by goodwill resulting from an acquisition completed in 2014.

Line of Credit	9. LINE OF CREDIT On July 11, 2006, we entered into a loan agreement providing for an available line of credit of $30.0 million, which was most recently amended on March 15, 2012. Loans under the Amended and Restated Loan Agreement, as amended, bear interest at the rate of LIBOR plus a fixed percentage between 1.50% and 2.00%. The Amended and Restated Loan Agreement required us to maintain a minimum cash balance of $25 million and tangible net worth measured at the end of each of our fiscal quarters. The term of the Amended and Restated Loan Agreement, as amended, expired on March 31, 2015. We did not extend the loan agreement and we did not draw on this line of credit in 2015, 2014 or 2013.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Measurements	10. FAIR VALUE MEASUREMENTS The guidance on fair value measurements and disclosures defines fair value, establishes a framework for measuring fair value, and requires enhanced disclosures about assets and liabilities measured at fair value. Fair value is defined as the price at which an asset could be exchanged in a current transaction between knowledgeable, willing parties. A liability’s fair value is defined as the amount that would be paid to transfer the liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are used to determine fair value. These models employ valuation techniques that involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity. Assets and liabilities recorded at fair value on a recurring basis in our consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, defined by the guidance on fair value measurements, are directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities and are as follows: Level 1 - Valuation is based upon quoted market price for identical instruments traded in active markets. Level 2 - Valuation is based on quoted market prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 - Valuation is generated from model-based techniques that use significant assumptions not observable in the market. Valuation techniques include use of discounted cash flow models and similar techniques. Fair Value on a Recurring Basis Assets and liabilities measured at fair value on a recurring basis are categorized in the tables below based upon the lowest level of significant input to the valuations: Years ended December 31, 2015 Level 1 Level 2 Level 3 Assets: Short-term investments (1) $ 42,994 $ — $ — Total $ 42,994 $ — $ — Liabilities: Contingent consideration (2) $ — $ — $ 2,695 Total $ — $ — $ 2,695 Years ended December 31, 2014 Level 1 Level 2 Level 3 Assets: Short-term investments (1) $ 64,995 $ — $ — Total $ 64,995 $ — $ — Liabilities: Contingent consideration (2) $ — $ — $ 600 Total $ — $ — $ 600 (1) Short-term investments in the accompanying consolidated balance sheets are six-month U.S. Treasury Bills. The fair values of these assets are based on Level 1 inputs in the fair value hierarchy. (2) Contingent consideration liability represents arrangements to pay the former owners of certain companies we acquired. The undiscounted maximum payment under the arrangements was $7.9 million at the end of fiscal 2015, based on future revenues, gross profits and certain milestones. We estimated the fair value of the contingent consideration using a Monte Carlo Simulation, which is based on significant inputs, primarily forecasted future results of the acquired businesses, not observable in the market, and thus represents a Level 3 measure. Contingent consideration liability is included in Other long-term liabilities on our consolidated balance sheets.

The favorable tax rate ruling requires us to maintain a certain level of manufacturing operations in Switzerland. The aggregate dollar effect of this favorable tax rate was approximately $2.7 million, or $0.16 per share, in the year ended December 31, 2015, $1.9 million, or $0.11 per share, in the year ended December 31, 2014, and $1.5 million, or $0.09 per share, in the year ended December 31, 2013. Our domestic entities had deferred income tax assets in the amount of $5.2 million as of December 31, 2015 and December 31, 2014. At December 31, 2015 and 2014, our foreign subsidiaries had deferred tax assets primarily relating to net operating losses, some of which expire in the next 1 to 18 years and others which can be carried forward indefinitely, of $6.6 million and $9.2 million, respectively. The valuation allowance for deferred tax assets as of December 31, 2015 and 2014 was $0.8 million and $1.8 million, respectively. The net decrease in the total valuation allowance for each of years ended December 31, 2015, 2014 and 2013, was $1.0 million, $5.0 million and $0.2 million, respectively. During the year ended December 31, 2014, we identified certain immaterial errors related to deferred tax assets and the related valuation allowance. As a result, we decreased deferred tax assets and the related valuation allowance by $4.7 million each to correct the gross-up error. The above table has been adjusted to reflect this adjustment. We believe this error was not material to the consolidated financial statements of any prior interim or annual periods and that the correction of the error was not material to the 2014 consolidated financial statements. The valuation allowance as of December 31, 2015 and 2014 was primarily related to foreign net operating loss carryforwards that, in the judgment of management, were not more likely than not to be realized. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the periods in which those temporary differences are deductible. Management considers the scheduled reversal of deferred tax liabilities (including the impact of available carryback and carryforward periods), projected taxable income, and tax-planning strategies in making this assessment. In 2014, certain foreign subsidiaries, which had previously generated losses, established a pattern of profitability which resulted in the Company concluding that the valuation allowance should be reversed based on the assessment previously described. As a result, in 2014, we recorded a $4.5 million discrete tax adjustment. The remaining changes impacting the valuation allowance for the year ended December 31, 2014 related to changes in foreign currency. We have not recognized any U.S. tax expense on undistributed international earnings, as we intend to reinvest the earnings outside the U.S. for the foreseeable future. Our net undistributed international earnings were approximately $119.5 million and $106.2 million at December 31, 2015 and 2014, respectively. Significant judgment is required in determining our worldwide provision for income taxes. In the ordinary course of a global business, there are many transactions for which the ultimate tax outcome is uncertain. We review our tax contingencies on a regular basis and make appropriate accruals as necessary. As of December 31, 2015 and 2014, our unrecognized tax benefits totaled $0.3 million, which includes approximately $0.03 million of interest and penalties. We estimate that the unrecognized tax benefits will not change significantly within the next year. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: Years ended December 31, 2015 2014 2013 Balance at January 1, $ 265 $ 265 $ 265 Additions based on tax positions related to the current year — — — Additions for tax positions of prior years — — — Reductions for tax positions of prior years — — — Settlements — — — Balance at December 31, $ 265 $ 265 $ 265 We file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. The table below summarizes the open tax years and ongoing tax examinations in major jurisdictions as of December 31, 2015: Jurisdiction Open Years Examination United States - Federal Income Tax 2012-2015 N/A United States - various states 2011-2015 N/A Germany 2010-2015 2010-2012 Switzerland 2014-2015 N/A Singapore 2011-2015 N/A We recognize accrued interest and penalties related to unrecognized tax benefits in income tax expense. The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $0.3 million. We do not currently anticipate that the total amount of unrecognized tax benefits will result in material changes to our financial position. We are subject to income taxes at the federal, state and foreign country level. Our tax returns are subject to examination at the U.S. federal level from 2011 forward and at the state level subject to a three to four year statute of limitations. In September 2013, the U.S. Internal Revenue Service issued new regulations for capitalizing and deducting costs incurred to acquire, produce, or improve tangible property. We adopted these new regulations as of January 1, 2014, and it did not have a material effect on our consolidated financial statements.

Stock Compensation Plans	14. STOCK COMPENSATION PLANS We have three compensation plans that provide for the granting of stock options and other share-based awards to key employees and non-employee members of the Board of Directors. The 2004 Equity Incentive Plan (“2004 Plan”), the 2009 Equity Incentive Plan (“2009 Plan”), and the 2014 Equity Incentive Plan (“2014 Plan”) provide for granting options, restricted stock, restricted stock units or stock appreciation rights to employees and non-employee directors. We were authorized to grant awards for up to 1,750,000 shares of common stock under the 2004 Plan, of which 69,587 options are outstanding at December 31, 2015 at exercise prices between $13.04 and $24.36. We were also authorized to grant awards for up to 1,781,546 shares of common stock under the 2009 Plan, as well as any shares underlying awards outstanding under the 2004 Plan as of the effective date of the 2009 Plan that thereafter terminated or expired unexercised or were canceled, forfeited or lapsed for any reason. There are 677,869 options outstanding at December 31, 2015 under the 2009 Plan at exercise prices between $24.30 and $57.54. The options outstanding under the 2004 Plan and the 2009 Plan have a 10-year term (7 years on grants beginning in 2010) and vest over a 3-year period. In May 2014, our shareholders approved the 2014 Plan authorizing us to grant awards for up to 1,974,543 shares of common stock, as well as any shares underlying awards outstanding under the 2004 Plan and 2009 Plan as of the effective date of the 2014 Plan that thereafter terminate or expire unexercised or are canceled, forfeited or lapse for any reason. There are 339,452 options outstanding at December 31, 2015 under the 2014 Plan at exercise prices between $29.98 and $62.63. The options outstanding under the 2014 Plan have a 7-year term and generally vest over a 3-year period. We will not make any further grants under the 2004 Plan or the 2009 Plan. Beginning in 2013, upon election to the Board, each non-employee director receives an initial equity grant of shares of restricted common stock with a value equal to $100,000, calculated using the closing share price on the date of the non-employee director’s election to the Board. The initial restricted stock grant vests on the third anniversary of the grant date, subject to the non-employee director’s continued membership on the Board. Annually, the non-employee directors are granted restricted shares equal to 50% of their compensation on the first business day following the annual meeting of shareholders, calculated using the closing price of our common stock on that day. The shares of restricted stock vest on the day prior to the following year’s annual meeting date, subject to a non-employee director’s continued membership on the Board. We record compensation cost associated with our restricted stock unit grants on a straight-line basis over the vesting term. Annually, upon approval by our Compensation Committee, we grant stock options and restricted stock units to certain employees. We also grant stock options to certain new employees throughout the year. These awards are non-performance-based subject only to time-based vesting, and vest in three equal annual installments beginning one year after the grant date. The related stock-based compensation is recognized over the requisite service period. In 2015, we began granting performance-based stock options and restricted stock units to certain executives. These awards vest in three equal annual installments beginning one year after the grant date if the applicable performance goals or strategic objectives are achieved. The related stock-based compensation expense is recognized over the requisite service period, taking into account the probability that we will satisfy the performance goals or strategic objectives. In addition to certain strategic objectives, the awards to be issued under the 2015 performance-based stock options and restricted stock unit grant are determined based on (1) our achievement of specified revenue and EPS targets, and (2) our total shareholder return (TSR) relative to the TSR attained by companies within our defined peer group. Due to the TSR presence in certain performance-based grants, the fair value of these awards is determined using the Monte Carlo Simulation valuation model. We expense these market condition awards over the three-year vesting period regardless of the value that the award recipients ultimately receive. Monte Carlo Simulation valuation models incorporate assumptions as to stock price volatility, the expected life of options or awards, a risk-free interest rate and dividend yield. The weighted average fair value of the stock options and restricted stock units that were granted in 2015 and valued based on the Monte Carlo Simulation valuation model was $19.97 and $44.45, respectively. The assumptions used to estimate the fair value of the performance-based stock options and restricted stock units granted in 2015 under the Monte Carlo Simulation model are as follows: Years Ended December 31, 2015 2014 2013 Risk-free interest rate 0.95% - 1.48 % — — Expected dividend yield 0 % — — Expected option life 4 years — — Expected volatility 44.5 % — — Weighted-average expected volatility 44.5 % — — For stock options granted using the Black-Scholes option-pricing model, we used the following assumptions: Years Ended December 31, 2015 2014 2013 Risk-free interest rate 0.80% - 1.21 % 0.95% - 1.32 % 0.55% - 1.03 % Expected dividend yield 0 % 0 % 0 % Expected option life 3 years 3-4 years 4 years Expected volatility 42.3% - 48.5 % 42.5% - 45.4 % 46.1% - 48.4 % Weighted-average expected volatility 43.5 % 42.6 % 48.2 % Historical information was the primary basis for the selection of the expected dividend yield, expected volatility and the expected lives of the options. The risk-free interest rate was based on yields of U.S. zero coupon issues and U.S. Treasury issues, with a term equal to the expected life of the option being valued. A summary of stock option activity and weighted average exercise prices follows: Options Weighted- Weighted-Average Aggregate Intrinsic Outstanding at January 1, 2015 898,429 $ 44.40 Granted 528,005 55.21 Forfeited (181,063 ) 55.68 Exercised (66,786 ) 33.11 Outstanding at December 31, 2015 1,178,585 $ 48.14 4.2 $ 1,382 Options exercisable at December 31, 2015 566,428 $ 42.14 2.4 $ 1,382 The weighted-average grant-date fair value of the stock options granted during the years ended December 31, 2015, 2014 and 2013 were $15.08, $19.38 and $14.41, respectively. The aggregate intrinsic value of stock options exercised during the years ended December 31, 2015, 2014 and 2013 was $1.7 million, $2.2 million and $3.7 million, respectively. The total fair value of stock options using the Black-Scholes option pricing model vested during the years ended December 31, 2015, 2014 and 2013 was $3.9 million, $3.7 million and $3.3 million, respectively. The following table summarizes the restricted stock activity and weighted average grant-date fair values for the year ended December 31, 2015: Shares Weighted-Average Non-vested at January 1, 2015 13,955 $ 43.57 Granted 16,892 43.26 Forfeited (1,582 ) 46.15 Vested (13,349 ) 42.99 Non-vested at December 31, 2015 15,916 $ 43.47 We recorded total stock-based compensation expense associated with our stock incentive plans of $4,306, $4,678 and $4,409 in 2015, 2014 and 2013, respectively. As of December 31, 2015, there was $7.0 million in total unrecognized stock-based compensation expense related to non-vested stock-based compensation arrangements. The expense is expected to be recognized over a weighted average period of 1.7 years.

Earnings Per Share

Earnings Per Share	12 Months Ended
	Dec. 31, 2015
Earnings Per Share	15. EARNINGS PER SHARE Basic earnings per share is computed by dividing net income by the weighted average number of shares outstanding. Diluted earnings per share is computed by also considering the impact of potential common stock on both net income and the weighted average number of shares outstanding. Our potential common stock consists of employee and director stock options, restricted stock, restricted stock units and performance-based awards. Our potential common stock is excluded from the basic earnings per share calculation and is included in the diluted earnings per share calculation when doing so would not be anti-dilutive. Performance-based awards are included in the computation of diluted earnings per share only to the extent that the underlying performance conditions (and any applicable market condition) (i) are satisfied as of the end of the reporting period or (ii) would be considered satisfied if the end of the reporting period were the end of the related contingency period and the result would be dilutive under the treasury stock method.

Business Combinations	18. BUSINESS COMBINATIONS In February 2015, we completed the acquisition of ARAS 360 Technologies Inc. (“ARAS”) for a purchase price of $7.7 million, paid with cash on hand, subject to certain additional post-closing adjustments, and up to an additional $4.0 million in contingent consideration that may be earned over a two-year period. ARAS, a privately-held business headquartered in Canada, produces a full suite of accident and crime reconstruction software tools that offer advanced graphics, analytical tools, and the ability to work with large point cloud data. The acquisition is expected to complement our portfolio within the public safety market. In March 2015, we completed the acquisition of kubit GmbH for a purchase price of $4.5 million, paid with cash on hand, subject to certain additional post-closing adjustments, and up to an additional $3.3 million in contingent consideration that may be earned over a three-year period. The acquisition also included substantially all of the assets of kubit GmbH’s U.S. distributor kubit USA, Inc. (collectively “kubit”). Kubit, a privately-held business with operating facilities in Germany and the United States, develops software for surveying and as-built documentation. The acquisition is expected to complement our portfolio of software products, specifically in the building information modeling/ construction information management market. The acquisition of each of ARAS and kubit constitutes a business combination as defined by the FASB Accounting Standards Codification (“ASC”) Topic 805, Business Combinations. Accordingly, the assets acquired and liabilities assumed were recorded at their fair values on the date of acquisition. Following is a summary of our allocation of the purchase price to the fair values of the assets acquired and liabilities assumed as of the date of each acquisition: ARAS kubit Tangible assets acquired: Accounts receivable $ 294 $ 136 Other assets — $ 246 Total assets acquired 294 382 Liabilities assumed: Accounts payable and accrued liabilities 27 182 Other liabilities 219 489 Total liabilities assumed 246 671 Intangible assets Trade name 509 658 Non-competition agreement 540 272 Technology 2,052 945 Customer relationship 2,250 696 Total intangible assets 5,351 2,571 Net assets acquired 5,399 2,282 Deferred tax liability (1,385 ) (674 ) Goodwill 4,964 3,805 Contingent consideration (1,338 ) (987 ) Purchase price, net of cash acquired and post-closing adjustments $ 7,640 $ 4,426 The goodwill arising from the acquisitions consists largely of the expected synergies from combining operations as well as the value of the workforce. Intangible assets acquired with ARAS and kubit will be amortized over a weighted-average life of about 8 years. The intangible assets and goodwill of ARAS were assigned to the Americas reporting unit and the kubit intangible assets and goodwill were mainly assigned to the Europe/Africa reporting unit. The goodwill value is not expected to be tax deductible. Acquisition and integration costs are not included as components of consideration transferred, but are recorded as expense in the period in which such costs are incurred. To date, we have incurred approximately $0.2 million in acquisition and integration costs for each of the ARAS and kubit acquisitions. We have not furnished pro forma financial information related to our acquisitions of ARAS and kubit because such information is not material individually or in the aggregate to our overall financial results.

Inventories	Inventories Service inventory is typically used to provide a temporary replacement product to a customer covered by a premium warranty when the customer’s unit requires service or repair and as training equipment. Service inventory is available for sale; however, management does not expect service inventory to be sold within 12 months and, as such, classifies this inventory as a long-term asset. Service inventory that we utilize for training or repairs which we deem as no longer available for sale is transferred to fixed assets at the lower of cost or net realizable value and depreciated over its remaining useful life, typically three years. We transferred $3.0 million of service inventory to “Property and Equipment” in 2015.

Property and Equipment	Property and Equipment Machinery, equipment and software 2 to 5 years Furniture and fixtures 3 to 10 years Leasehold improvements are amortized on a straight-line basis over the lesser of the life of the asset or the remaining term of the lease. Depreciation expense was $9,238, $6,171 and $5,825 in 2015, 2014 and 2013, respectively. Accelerated methods of depreciation are used for income tax purposes in contrast to book purposes, and as a result, appropriate provisions are made for the related deferred income taxes.
Goodwill and Intangibles	Goodwill and Intangibles Each period, and for any of our reporting units, we can elect to perform a qualitative assessment to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. If we believe, as a result of our qualitative assessment, that it is not more likely than not that the fair value of a reporting unit containing goodwill is less than its carrying amount, then the first and second steps of the quantitative goodwill impairment test are unnecessary. If we elect to bypass the qualitative assessment option, or if the qualitative assessment was performed and resulted in the Company being unable to conclude that it is not more likely than not that the fair value of a reporting unit containing goodwill is greater than its carrying amount, we will perform the two-step quantitative goodwill impairment test. We perform the first step of the two-step quantitative goodwill impairment test by calculating the fair value of the reporting unit using a discounted cash flow method and market approach method, and then comparing the respective fair value with the carrying amount of the reporting unit. If the carrying amount of the reporting unit exceeds its fair value, we perform the second step of the quantitative goodwill impairment test to measure the amount of the impairment loss, if any. Management has concluded there was no goodwill impairment for the years ended December 31, 2015, 2014 and 2013. Other intangible assets principally include patents, existing product technology and customer relationships that arose in connection with our acquisitions. Other intangible assets are recorded at fair value at the date of acquisition and are amortized over their estimated useful lives of 3 to 20 years. As of December 31, 2015, there were no indefinite-lived intangible assets. Product technology and patents are recorded at cost. Amortization is computed using the straight-line method over the lives of the product technology and patents of 7 to 20 years. The remaining weighted-average amortization period for all our intangible assets is nine years.

Income Taxes	Income Taxes We recognize tax benefits related to uncertain tax positions only if it is more likely than not that the tax position will be sustained upon examination by taxing authorities. For those positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. In the ordinary course of business, we are examined by various federal, state, and foreign tax authorities. We regularly assess the potential outcomes of these examinations and any future examinations for the current or prior years in determining the adequacy of our provision for income taxes.
Earnings Per Share	Earnings Per Share (EPS) Earnings Per Share
Accounting for Stock-Based Compensation	Accounting for Stock-Based Compensation Stock Compensation Plans We measure and record compensation expense using the applicable accounting guidance for share-based payments related to stock options, restricted stock, and performance-based awards granted to our directors and employees. The fair value of stock options, including performance awards, without a market condition is estimated, at the date of grant, using the Black-Scholes option-pricing model. The fair value of restricted stock awards and stock options with a market condition is estimated, at the date of grant, using the Monte Carlo Simulation model. The Black-Scholes and Monte Carlo Simulation valuation models incorporate assumptions as to stock price volatility, the expected life of options or awards, a risk-free interest rate and dividend yield. In valuing our stock options, significant judgment is required in determining the expected volatility of our common stock and the expected life that individuals will hold their stock options prior to exercising. Expected volatility for stock options is based on the historical and implied volatility of our own common stock while the volatility for our restricted stock units with a market condition is based on the historical volatility of our own stock and the stock of companies within our defined peer group. The expected life of stock options is derived from the historical actual term of option grants and an estimate of future exercises during the remaining contractual period of the option. While volatility and estimated life are assumptions that do not bear the risk of change subsequent to the grant date of stock options, these assumptions may be difficult to measure as they represent future expectations based on historical experience. Further, our expected volatility and expected life may change in the future, which could substantially change the grant-date fair value of future awards of stock options and, ultimately, the expense we record. The fair value of restricted stock, including performance awards, without a market condition is estimated using the current market price of our common stock on the date of grant. Additionally, in calculating compensation expense for these awards, we are also required to estimate the extent to which awards will be forfeited prior to vesting. Many factors are considered when estimating expected forfeitures, including types of awards, employee class and historical experience. To the extent actual results or updated estimates of forfeiture differ from current estimates, such amounts are recorded as a cumulative adjustment to the previously recorded amounts. We expense stock-based compensation for stock options, restricted stock awards, and performance awards over the requisite service period. For awards with only a service condition, we expense stock-based compensation, adjusted for estimated forfeitures, using the straight-line method over the requisite service period for the entire award. For awards with both performance and service conditions, we expense the stock-based compensation, adjusted for estimated forfeitures, on a straight-line basis over the requisite service period for each separately vesting portion of the award, taking into account the probability that we will satisfy the performance conditions. Furthermore, we expense awards with a market condition over the three-year vesting period regardless of the value that the award recipients ultimately receive. Excess tax benefits are credited to common stock when the deduction reduces cash taxes payable. When we have tax deductions in excess of the compensation cost, they are classified as financing cash inflows in the Consolidated Statements of Cash Flows.

Impact of Recently Issued Accounting Standards	Impact of Recently Issued Accounting Standards In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory, which changes the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. ASU 2015-11 defines net realizable value as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The new guidance must be applied on a prospective basis and is effective for fiscal years beginning after December 15, 2015, and interim periods within those years, with early adoption permitted. We do not believe the implementation of this standard will have a material impact on our consolidated financial statements. In May 2014, the FASB issued an amendment to its accounting guidance related to revenue recognition. The amendment was the result of a joint project between the FASB and the International Accounting Standards Board (“IASB”) to clarify the principles for recognizing revenue and to develop common revenue standards for U.S. GAAP and International Financial Reporting Standards. To meet those objectives, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers: Topic 606 (“ASU 2014-09”). ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the FASB issued ASU 2015-14, Revenue from contracts with customers (Topic 606): Deferral of the Effective Date, deferring the effective date of ASU 2014-09 by one year. With this deferral, the new standard is effective for us on January 1, 2018. The standard permits the use of either the retrospective or cumulative effective transition method. We are evaluating the impact of adopting this standard on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.

The undiscounted maximum payment under the arrangements was $7.9 million at the end of fiscal 2015, based on future revenues, gross profits and certain milestones. We estimated the fair value of the contingent consideration using a Monte Carlo Simulation, which is based on significant inputs, primarily forecasted future results of the acquired businesses, not observable in the market, and thus represents a Level 3 measure. Contingent consideration liability is included in Other long-term liabilities on our consolidated balance sheets.

[1]	Short-term investments in the accompanying consolidated balance sheets are six-month U.S. Treasury Bills. The fair values of these assets are based on Level 1 inputs in the fair value hierarchy.
[2]	Contingent consideration liability represents arrangements to pay the former owners of certain companies we acquired. The undiscounted maximum payment under the arrangements was $7.9 million at the end of fiscal 2015, based on future revenues, gross profits and certain milestones. We estimated the fair value of the contingent consideration using a Monte Carlo Simulation, which is based on significant inputs, primarily forecasted future results of the acquired businesses, not observable in the market, and thus represents a Level 3 measure. Contingent consideration liability is included in Other long-term liabilities on our consolidated balance sheets.
