Description of Business	DESCRIPTION OF BUSINESS FARO Technologies, Inc. and its subsidiaries (collectively “FARO,” the “Company,” “us,” “we” or “our”) design, develop, manufacture, market and support software driven, three-dimensional (3D) measurement, imaging and realization systems. We sell the majority of our products through a direct sales force across a broad number of customers in a range of manufacturing, industrial, architecture, surveying, building information modeling, construction, public safety forensics, cultural heritage and other applications. Our FaroArm^®, FARO Laser ScanArm^®, FARO Gage, FARO Laser Tracker^TM, FARO Cobalt Array Imager, and their companion CAM2^® software, provide for Computer-Aided Design, or CAD, based inspection and/or factory-level statistical process control and high-density surveying.

Principles of Consolidation	PRINCIPLES OF CONSOLIDATION Our condensed consolidated financial statements include the accounts of FARO Technologies, Inc. and its subsidiaries, all of which are wholly owned. All intercompany transactions and balances have been eliminated. The financial statements of our foreign subsidiaries are translated into U.S. dollars using exchange rates in effect at period-end for assets and liabilities and average exchange rates during each reporting period for results of operations. Adjustments resulting from financial statement translations are reflected as a separate component of accumulated other comprehensive income. Foreign currency transaction gains and losses are included in income.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The condensed consolidated financial statements and notes thereto are unaudited. These statements include all normal recurring accruals and adjustments considered necessary by management for their fair presentation in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. The condensed consolidated results of operations for the three months and nine months ended September 30, 2016 are not necessarily indicative of results that may be expected for the year ending December 31, 2016 or any future interim period. The information included in this Quarterly Report on Form 10-Q, including the interim condensed consolidated financial statements and the accompanying notes, should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015. The accompanying December 31, 2015 condensed consolidated balance sheet has been derived from those audited consolidated financial statements. Prior to January 1, 2016, we used a 4-4-5 fiscal quarter end for interim financial reporting. Effective January 1, 2016, we transitioned to calendar quarters for interim financial reporting. As such, September 30, 2016 is the end of our third quarter of fiscal year 2016 instead of October 1, 2016. We believe this change had minimal impact on the presentation of the comparative periods in this Quarterly Report on Form 10-Q and will not impact the presentation of our future annual consolidated financial statements in our Annual Report on Form 10-K.

Accounting Changes and Error Corrections [Abstract]
Impact of Recently Issued Accounting Pronouncements	IMPACT OF RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), which clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows. ASU 2016-15 is effective for annual periods beginning after December 15, 2017, and interim periods therein. Early adoption is permitted. We do not expect the adoption of this guidance will have a material impact on our consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers: (Topic 606) (“ASU 2014-09”), amending its accounting guidance related to revenue recognition. Under this ASU and subsequently issued amendments, 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. Additional disclosures are required to provide 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. The ASU and subsequently issued amendments to the revenue recognition accounting guidance are effective for us on January 1, 2018 and permit the use of either the retrospective or cumulative effective transition method. We have not yet selected a transition method nor have we determined the effect of the revenue recognition accounting guidance on our ongoing financial reporting. In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), which is intended to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods therein (our fiscal year 2017). Early application is permitted. We are evaluating the impact of adopting this standard on our consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”), which is intended to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements to enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. ASU 2016-02 must be applied on a modified retrospective basis and is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. We are evaluating the impact of adopting this standard on our consolidated financial statements and related disclosures. In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16”), which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Instead, acquirers must recognize measurement-period adjustments during the period in which the amounts are determined. We adopted ASU 2015-16 effective as of January 1, 2016. The implementation of this standard did not have an impact on our consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory (“ASU 2015-11”), 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, 2016, 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.

Stock-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based Compensation

STOCK-BASED COMPENSATION

Stock-based compensation expense reflects the fair value of stock-based awards measured at the grant date and is recognized over the requisite service period.

We have three compensation plans that provide for the granting of stock options and other share-based awards to key employees and 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 directors. There are awards still outstanding under the 2004 Plan and 2009 Plan; however, we will not make any further grants under either of those plans.

Annually, we grant restricted stock to our directors. These director awards are granted the day following our Annual Meeting of Shareholders during the second quarter of each fiscal year and vest the day before our Annual Meeting of Shareholders in the following year, subject to a director’s continued membership on the board. The fair value of these awards is determined by using the current market price of our common stock on the grant date.

Annually, upon approval by our Compensation Committee, we grant stock options and restricted stock units to certain employees. We also grant stock options and restricted stock units to certain new employees throughout the year. Prior to 2016, these awards vested in three equal annual installments beginning one year after the grant date. The fair value of these stock-based awards is determined by using (a) the current market price of our common stock on the grant date in the case of restricted stock units or (b) the Black-Scholes option valuation model in the case of stock options.

In 2015, we granted performance-based stock options and restricted stock units to certain executives. These awards vest in three annual installments beginning one year after the grant date if the applicable performance measures 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 measures or strategic objectives. In addition to certain strategic objectives, the performance-based stock options and restricted stock units granted in 2015 are earned and vest based upon (1) our achievement of specified revenue and earnings per share 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 the award recipients ultimately receive. In February 2016, our Compensation Committee determined the number of performance-based stock options and restricted stock units that were earned for the 2015 performance period. Based on the performance and strategic objectives achieved in 2015, 7,225 stock options and 226 restricted stock units were earned and vested and 23,328 stock options and 677 restricted stock units were determined to be unearned, as the required metrics were not achieved.

We did not grant performance-based stock options and restricted stock units to our employees during the nine months ended September 30, 2016. Instead, our annual grant in March 2016 consisted of stock options and restricted stock units that are subject to only time-based vesting. The number of stock options and/or restricted stock units granted was based on the employee’s individual objectives, performance against operational metrics assigned to the employee and overall contribution over the last year. The restricted stock unit awards vest in full on the three-year anniversary of the grant date. The stock options vest in three equal annual installments beginning one year after the grant date. The fair value of these stock-based awards is determined by using (a) the current market price of our common stock on the grant date in the case of restricted stock units or (b) the Black-Scholes option valuation model in the case of stock options.

In May 2016, we granted an aggregate of 18,615 restricted stock units to certain non-executive key employees as a retention incentive in recognition of the significant efforts required from such employees to assist us in executing our initiatives in 2016 to reorganize our business around certain vertical markets, modernize our sales process to improve the efficiency of our sales organization, accelerate and maintain a consistent schedule of new product introductions, and harmonize our global functions to improve effectiveness. These restricted stock unit awards vest in full on the three-year anniversary of the grant date. The fair value of these restricted stock units is determined by using the current market price of our common stock on the grant date.

The Black-Scholes option valuation model incorporates assumptions as to stock price volatility, the expected life of options or awards, a risk-free interest rate and dividend yield. The weighted-average grant-date fair value of the stock options that were granted during the nine months ended September 30, 2016 and September 26, 2015 and valued using the Black-Scholes option valuation model was $12.42 and $16.33 per option, respectively. For stock options granted during the nine months ended September 30, 2016 and September 26, 2015 valued using the Black-Scholes option valuation model, we used the following assumptions:



	Nine Months Ended
	September 30, 2016		September 26, 2015
Risk-free interest rate	1.06% - 1.21%		0.80% - 1.09%
Expected dividend yield	—	%	—	%
Expected option life	4 years		3 years
Expected volatility	46.7% - 47.0%		42.3% - 48.5%
Weighted-average expected volatility	46.7	%	43.1	%

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 the 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.

There were no market condition awards granted during the nine months ended September 30, 2016 and, as such, the Monte Carlo Simulation valuation model was not used to determine the fair value of the stock options and restricted stock units granted in the first, second or third quarter of 2016. In 2015, we granted performance-based stock options and restricted stock units which included the presence of a market condition and were valued using the Monte Carlo Simulation model. This valuation model incorporates assumptions as to stock price volatility, the expected life of options or awards, a risk-free interest rate and dividend yield. The assumptions used to estimate the fair value of the performance-based stock options and restricted stock units granted during the nine months ended September 26, 2015 and valued under the Monte Carlo Simulation model were as follows:



	Nine Months Ended
	September 30, 2016		September 26, 2015
Risk-free interest rate	—	%	0.95% - 1.48%
Expected dividend yield	—	%	—	%
Expected option life	—		4 years
Expected volatility	—	%	44.5	%

Inventory Disclosure [Abstract]

Inventories

INVENTORIES

Inventories are stated at the lower of cost or net realizable value using the first-in first-out (FIFO) method. Shipping and handling costs are classified as a component of cost of sales in the consolidated statements of operations. Sales demonstration inventory is comprised of measuring, imaging and realization devices utilized by sales representatives to present our products to customers. We expect sales demonstration inventory to be held by our sales representatives for up to three years, at which time it would be refurbished and transferred to finished goods as used equipment, stated at the lower of cost or net realizable value. Management expects these refurbished units to remain in finished goods inventory and to be sold within twelve months at prices that may produce reduced gross margins. Sales demonstration inventory is classified as inventory, as it is available for sale and any required refurbishment prior to sale is minimal.

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.

Inventories consist of the following:



	As of September 30, 2016		As of December 31, 2015
Raw materials	$	34,508	$	28,190
Finished goods	20,698		17,381

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

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. In 2015, we granted performance-based stock options and restricted stock units. These 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) (a) are satisfied as of the end of the reporting period or (b) 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. For the three and nine months ended September 30, 2016 there were approximately 1,002,856 and 1,042,366, respectively, additional shares issuable upon exercise of anti-dilutive options and contingent vesting of performance-based awards, which were excluded from the dilutive calculations. The effect of 1,199,397 and 797,844 additional shares were not included in the dilutive calculations for the three and nine months ended September 26, 2015, respectively.

A reconciliation of the number of common shares used in the calculation of basic and diluted earnings per share (“EPS”) is presented below:

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES For the three months ended September 30, 2016, we recorded income tax benefit of $0.1 million compared with $0.2 million for the three months ended September 26, 2015. Our effective tax rate was a 5.9% benefit for the three months ended September 30, 2016 compared with a 16.6% benefit in the prior year period. This decrease of $0.1 million in income tax benefit and the change in our effective rate was due to the increase in pretax income during the third quarter of 2016 compared with a pretax loss in the same period of 2015 and the geographical mix shift in pretax income expected for the full year 2016. Income tax expense increased by $0.5 million to $1.4 million for the nine months ended September 30, 2016 from $0.9 million for the nine months ended September 26, 2015. Our effective tax rate decreased by 3.8 percentage points to 15.6% for the nine months ended September 30, 2016 from 19.4% for the same prior year period. Our effective tax rate continued to be lower than the statutory tax rate in the United States, mainly due to our global footprint in foreign jurisdictions with lower tax rates. However, our effective tax rate could be impacted positively or negatively by geographic changes in the manufacturing or sales of our products and the resulting effect on taxable income in each jurisdiction.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

FAIR VALUE OF FINANCIAL INSTRUMENTS

Our financial instruments include cash and cash equivalents, short-term investments, accounts receivable, customer deposits, accounts payable and accrued liabilities. The carrying amounts of such financial instruments approximate their fair value due to the short-term nature of these instruments.

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:



	As of September 30, 2016
	Level 1		Level 2		Level 3
Assets:
Short-term investments (1)	$	31,957	$	—	$	—
Total	$	31,957	$	—	$	—
Liabilities:
Contingent consideration (2)	$	—	$	—	$	2,322
Total	$	—	$	—	$	2,322
	As of December 31, 2015

Total	$	42,994	$	—	$	—
Liabilities:
Contingent consideration (2)	$	—	$	—	$	2,695
Total	$	—	$	—	$	2,695


(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, 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. For the three and nine months ended September 30, 2016, we paid $0.3 million and $0.4 million, respectively, as part of these arrangements. The remaining change in the fair value of the contingent consideration from December 31, 2015 to September 30, 2016 is related to changes in foreign currency.

BUSINESS COMBINATIONS

In August 2016, we acquired Laser Projection Technologies, Inc. (“LPT”) for a purchase price, net of cash acquired, of $17.1 million, paid with cash on hand, subject to certain additional post-closing adjustments. LPT, located in Londonderry, New Hampshire, specializes in laser projection and measurement systems used throughout manufacturing environments around the globe to maximize productivity and efficiency. The acquisition enhances our portfolio of 3D measurement solutions and supports our long-term strategy to expand our presence in key markets, which complement our existing product lines.

In July 2016, we acquired BuildIT Software & Solutions Ltd. (“BuildIT”) for a purchase price, net of cash acquired, of $3.8 million, paid with cash on hand, subject to certain additional post-closing adjustments. BuildIT, a software solutions business located in Montreal, Canada, specializes in process-configurable 3D metrology software solutions with hardware agnostic interfaces. The addition of BuildIT enhances our metrology portfolio, providing customers greater software options to use in a variety of applications to reduce inspection and assembly times and increase productivity.

The acquisitions of BuildIT and LPT constitute business combinations 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. The following preliminary purchase price allocations are based on the information that was available to make estimates of the fair value and may change as further information becomes available and additional analyses are completed. While we believe such information provided a reasonable basis for estimating the fair values, we may obtain more information and evidence during the measurement period that may result in changes to the estimated fair value amounts. The measurement period ends on the earlier of one year after the acquisition date or the date we received the information about the facts and circumstances that existed at the acquisition date. Subsequent adjustments, if necessary, will be recognized during the period in which the amounts are determined. These refinements include: (1) changes in the estimated fair value of certain intangible assets acquired; and (2) changes in deferred tax assets and liabilities related to the fair value estimates.

Following is a summary of our preliminary allocations of the purchase price to the fair values of the assets acquired and liabilities assumed as of the date of each acquisition:



	BuildIT			LPT
Accounts receivable	$	237		$	54
Inventory	—			322
Other assets	36			248
Deferred income tax assets	—			1,112
Intangible assets (1)	1,381			5,224
Goodwill (2)	3,042			11,922
Accounts payable and accrued liabilities	(95		)	(697		)
Other liabilities	(485		)	(1,086		)
Deferred income tax liability	(304		)	—

Total purchase price, net of cash acquired	$	3,812		$	17,099


(1)	Intangible assets acquired with BuildIT and LPT will be amortized over their weighted-average lives of about 7 to 10 years.


(2)	The goodwill arising from the acquisitions consists largely of the expected synergies from combining operations as well as the value of the workforce. 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 $0.7 million in acquisition and integration costs for the BuildIT and LPT acquisitions.

Pro forma results of operations for BuildIT and LPT have not been presented because the effects of these acquisitions, individually and in aggregate, were not material to our consolidated results of operations.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Principles of Consolidation (Policies)	9 Months Ended
Principles of Consolidation (Policies)	Sep. 30, 2016
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation Policy	Our condensed consolidated financial statements include the accounts of FARO Technologies, Inc. and its subsidiaries, all of which are wholly owned. All intercompany transactions and balances have been eliminated.
Foreign Currency Translations Policy	The financial statements of our foreign subsidiaries are translated into U.S. dollars using exchange rates in effect at period-end for assets and liabilities and average exchange rates during each reporting period for results of operations. Adjustments resulting from financial statement translations are reflected as a separate component of accumulated other comprehensive income. Foreign currency transaction gains and losses are included in income.
Basis of Accounting Policy	These statements include all normal recurring accruals and adjustments considered necessary by management for their fair presentation in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”).
Use of Estimates Policy	Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.
Reclassification Policy	During the third quarter of 2016, we reclassified certain service costs that were previously classified as product costs. This reclassification did not have a material impact on either the current or prior year periods. As such, the prior year amounts have not been reclassified in our condensed consolidated financial statements.
New Accounting Pronouncements Policy	In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), which clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows. ASU 2016-15 is effective for annual periods beginning after December 15, 2017, and interim periods therein. Early adoption is permitted. We do not expect the adoption of this guidance will have a material impact on our consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers: (Topic 606) (“ASU 2014-09”), amending its accounting guidance related to revenue recognition. Under this ASU and subsequently issued amendments, 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. Additional disclosures are required to provide 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. The ASU and subsequently issued amendments to the revenue recognition accounting guidance are effective for us on January 1, 2018 and permit the use of either the retrospective or cumulative effective transition method. We have not yet selected a transition method nor have we determined the effect of the revenue recognition accounting guidance on our ongoing financial reporting. In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), which is intended to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods therein (our fiscal year 2017). Early application is permitted. We are evaluating the impact of adopting this standard on our consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”), which is intended to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements to enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. ASU 2016-02 must be applied on a modified retrospective basis and is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. We are evaluating the impact of adopting this standard on our consolidated financial statements and related disclosures. In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16”), which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Instead, acquirers must recognize measurement-period adjustments during the period in which the amounts are determined. We adopted ASU 2015-16 effective as of January 1, 2016. The implementation of this standard did not have an impact on our consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory (“ASU 2015-11”), 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, 2016, 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.
Cash and Cash Equivalents Policy	We consider cash on hand and all short-term, highly liquid investments that have maturities of three months or less at the time of purchase to be cash and cash equivalents.
Inventory Policy	Inventories are stated at the lower of cost or net realizable value using the first-in first-out (FIFO) method. Shipping and handling costs are classified as a component of cost of sales in the consolidated statements of operations. Sales demonstration inventory is comprised of measuring, imaging and realization devices utilized by sales representatives to present our products to customers. We expect sales demonstration inventory to be held by our sales representatives for up to three years, at which time it would be refurbished and transferred to finished goods as used equipment, stated at the lower of cost or net realizable value. Management expects these refurbished units to remain in finished goods inventory and to be sold within twelve months at prices that may produce reduced gross margins. Sales demonstration inventory is classified as inventory, as it is available for sale and any required refurbishment prior to sale is minimal.

- Definition

Disclosure of accounting policy for cash and cash equivalents, including the policy for determining which items are treated as cash equivalents. Other information that may be disclosed includes (1) the nature of any restrictions on the entity's use of its cash and cash equivalents, (2) whether the entity's cash and cash equivalents are insured or expose the entity to credit risk, (3) the classification of any negative balance accounts (overdrafts), and (4) the carrying basis of cash equivalents (for example, at cost) and whether the carrying amount of cash equivalents approximates fair value.

Business Combinations [Abstract]

Schedule of Purchase Price Allocation to the Fair Values of Assets Acquired and Liabilities Assumed

Following is a summary of our preliminary allocations of the purchase price to the fair values of the assets acquired and liabilities assumed as of the date of each acquisition:



	BuildIT			LPT
Accounts receivable	$	237		$	54
Inventory	—			322
Other assets	36			248
Deferred income tax assets	—			1,112
Intangible assets (1)	1,381			5,224
Goodwill (2)	3,042			11,922
Accounts payable and accrued liabilities	(95		)	(697		)
Other liabilities	(485		)	(1,086		)
Deferred income tax liability	(304		)	—

Total purchase price, net of cash acquired	$	3,812		$	17,099


(1)	Intangible assets acquired with BuildIT and LPT will be amortized over their weighted-average lives of about 7 to 10 years.


(2)	The goodwill arising from the acquisitions consists largely of the expected synergies from combining operations as well as the value of the workforce. The goodwill value is not expected to be tax deductible.
