Accounting Policies [Abstract] |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 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:

The Company recognized amortization expense associated with the above intangible assets of $1.5 million and $1.6 million for the three months ended September 30, 2015 and 2014, respectively and $4.7 million and $4.8 million for the nine months ended September 30, 2015 and 2014, respectively. The annual aggregate amortization expense based on the current balance of other intangible assets is estimated at $6.2 million for 2015, $6.1 million for 2016, $5.7 million for 2017, $5.5 million for 2018, $5.2 million for 2019 and $4.9 million for 2020. Purchased intangible amortization was $1.3 million, $0.9 million after tax, and $1.5 million, $1.0 million after tax, for the three months ended September 30, 2015 and 2014, respectively and $4.2 million, $2.9 million after tax, and $4.2 million, $2.8 million after tax, for the nine months ended September 30, 2015 and 2014, respectively. In addition to the above amortization, the Company recorded amortization expense associated with capitalized software of $6.2 million and $5.5 million for the three months ended September 30, 2015 and 2014, respectively and $18.1 million and $16.7 million for the nine months ended September 30, 2015 and 2014, respectively. 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, such as customer acceptance, 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. Estimated 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 $3.4 million and $10.3 million of share-based compensation expense for the three and nine months ended September 30, 2015, respectively, compared to $3.3 million and $9.8 million for the corresponding periods in 2014. Research and Development Research and development costs primarily consist of salaries, consulting and other costs. The Company expenses these costs as incurred.
