SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Trade Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts represents the Company’s best estimate of probable credit losses in its existing trade accounts receivable. The Company determines the allowance based upon a review of both specific accounts for collection and the age of the accounts receivable portfolio.

Inventories

Inventories are valued at the lower of cost or net realizable value. Cost, which includes direct materials, labor and overhead, is generally determined using the first in, first out (FIFO) method. The estimated net realizable value is based on assumptions for future demand and related pricing. Adjustments to the cost basis of the Company’s inventory are made for excess and obsolete items based on usage, orders and technological obsolescence. If actual market conditions are less favorable than those projected by management, reductions in the value of inventory may be required.

Inventories consisted of the following:

Goodwill and Other Intangible Assets

Goodwill, representing the excess of purchase price over the net asset value of companies acquired, and indefinite-lived intangible assets are not amortized, but are reviewed for impairment annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that an asset might be impaired. The annual evaluation for goodwill and indefinite-lived intangible assets are generally based on an assessment of qualitative and quantitative factors to determine whether it is more likely than not that the fair value of the asset is less than its carrying amount.

Other intangible assets include indefinite-lived assets and assets subject to amortization. Where applicable, amortization is charged on a straight-line basis over the expected period of benefit. The straight-line method of amortization reflects an appropriate allocation of the cost of the intangible assets to earnings in proportion to the amount of economic benefits obtained by the Company in each reporting period. The Company assesses the initial acquisition of intangible assets in accordance with the provisions of ASC 805 "Business Combinations" and the continued accounting for previously recognized intangible assets and goodwill in accordance with the provisions of ASC 350 "Intangible - Goodwill and Other" and ASC 360 "Property, Plant and Equipment".

Other intangible assets consisted of the following:

Revenue Recognition

Revenue is recognized when title to a product has transferred and any significant customer obligations have been fulfilled. Standard shipping terms are generally FOB shipping point in most countries and, accordingly, title and risk of loss transfers upon shipment. In countries where title cannot legally transfer before delivery, the Company defers revenue recognition until delivery has occurred. The Company generally maintains the right to accept or reject a product return in its terms and conditions and also maintains appropriate accruals for outstanding credits. Shipping and handling costs charged to customers are included in total net sales and the associated expense is recorded in cost of sales for all periods presented. Other than a few small software applications, the Company does not sell software products without the related hardware instrument as the software is embedded in the instrument. The Company’s products typically require no significant production, modification or customization of the hardware or software that is essential to the functionality of the products. To the extent the Company’s solutions have a post-shipment obligation, revenue is deferred until the obligation has been completed. The Company defers product revenue where installation is required, unless such installation is deemed perfunctory. The Company also sometimes enters into certain arrangements that require the separate delivery of multiple goods and/or services. These deliverables are accounted for separately if the deliverables have standalone value and the performance of undelivered items is probable and within the Company's control. The allocation of revenue between the separate deliverables is typically based on the relative selling price at the time of the sale in accordance with a number of factors including service technician billing rates, time to install and geographic location.

Further, certain products are also sold through indirect distribution channels whereby the distributor assumes any further obligations to the customer upon title transfer. Revenue is recognized on these products upon transfer of title and risk of loss to its distributors. Distributor discounts are offset against revenue at the time such revenue is recognized.

Service revenue not under contract is recognized upon the completion of the service performed. Spare parts sold on a stand-alone basis are recognized upon title and risk of loss transfer which is generally at the time of shipment. Revenues from service contracts are recognized ratably over the contract period. These contracts represent an obligation to perform repair and other services including regulatory compliance qualification, calibration, certification and preventative maintenance on a customer’s pre-defined equipment over the contract period. Service contracts are separately priced and payment is typically received from the customer at the beginning of the contract period.

Warranty

The Company generally offers one-year warranties on most of its products. Product warranties are recorded at the time revenue is recognized. While the Company engages in extensive product quality programs and processes, its warranty obligations are affected by product failure rates, material usage and service costs incurred in correcting a product failure.

Employee Termination Benefits

In situations where contractual termination benefits exist, the Company records accruals for employee termination benefits when it is probable that a liability has been incurred and the amount of the liability is reasonably estimable. All other employee termination arrangements are recognized and measured at their fair value at the communication date unless the employee is required to render additional service beyond the legal notification period, in which case the liability is recognized ratably over the future service period.

Share-Based Compensation

The Company recognizes share-based compensation expense within selling, general and administrative in the consolidated statements of operations and other comprehensive income with a corresponding offset to additional paid-in capital in the consolidated balance sheet. The Company recorded $3.6 million and $7.2 million of share-based compensation expense for the three and six months ended June 30, 2016, respectively, compared to $3.5 million and $7.0 million for the corresponding periods in 2015.

Research and Development

Research and development costs primarily consist of salaries, consulting and other costs. The Company expenses these costs as incurred.

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, to ASC 606 "Revenue from Contracts with Customers." ASU 2014-09 provides authoritative guidance clarifying the principles for recognizing revenue and developing a common revenue standard for U.S. GAAP. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised 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 and services. Additionally, the guidance requires improved disclosure to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. The guidance becomes effective for the Company for the year beginning January 1, 2018. We are currently evaluating the impact the adoption of this guidance will have on the Company's consolidated results of operations, financial position, and disclosures.

In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers," which amends ASU 2014-09. The ASU provides guidance for assessing collectability, presentation of sales taxes, noncash considerations, and completed contract modifications at transition. The guidance becomes effective for the Company for the year beginning January 1, 2018. We are currently evaluating the impact the adoption of this guidance will have on the Company's consolidated results of operations, financial position, and disclosures.

In May 2016, the FASB issued ASU 2016-10, "Revenue from Contracts with Customers," which amends ASU 2014-09. The ASU provides guidance for identifying performance obligations as they pertain to immaterial promised goods or services, shipping and handling activities, and identifying when promises represent performance obligations. The guidance becomes effective for the Company for the year beginning January 1, 2018. We are currently evaluating the impact the adoption of this guidance will have on the Company's consolidated results of operations, financial position, and disclosures.

In March 2016, the FASB issued ASU 2016-09, to ASC 718 "Compensation - Stock Compensation." The guidance allows for the simplification related to several aspects of the accounting for share-based payment transactions, including income tax consequences, the accounting for forfeitures, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance can be applied either on a retrospective or prospective basis and becomes effective for annual periods beginning after December 15, 2016. We are currently evaluating the impact the adoption of this guidance will have on the Company's consolidated results of operations, financial position, and disclosures.

In February 2016, the FASB issued ASU 2016-02 to ASC 842 "Leases." The accounting guidance primarily requires lessees to recognize most leases on their balance sheet as a right to use asset and a lease liability, with the exception of short term leases. A lessee will continue to recognize lease expense on a straight-line basis for leases classified as operating leases. The guidance becomes effective for fiscal years beginning after December 15, 2018 and must be applied on a retrospective basis with early adoption permitted. The Company is currently evaluating the impact of this guidance on our financial statements and the timing of adoption.

In November 2015, the FASB issued ASU 2015-17, to ASC 740 "Income Taxes." The guidance simplifies the balance sheet classification of deferred taxes. The new guidance requires that all deferred tax balances be presented as non-current. This change, which can be early adopted, conforms U.S. GAAP to IFRS. The guidance becomes effective for the Company for the year beginning January 1, 2017. The adoption of this guidance would have reduced current assets and increased non-current assets by approximately $70.9 million and reduced current liabilities and increased non-current liabilities by approximately $22.9 million on the Company's consolidated balance sheet at June 30, 2016.

In May 2015, the FASB issued ASU 2015-07, to ASC 820 "Fair Value Measurements." ASU 2015-07 removes the requirement to categorize investments using the net asset value per share method within the fair value hierarchy. The Company will adopt the guidance in the fourth quarter of 2016, which will have an immaterial impact on the consolidated financial statements.
