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:

Raw materials and parts | $ | 125,197 |  |  | $ | 118,790 |
Work-in-progress | 50,546 |  |  | 43,035 |

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 $3.6 million and $2.9 million for the three months ended September 30, 2018 and 2017, respectively and $10.7 million and $7.9 million for the nine months ended September 30, 2018 and 2017, respectively. The annual aggregate amortization expense based on the current balance of other intangible assets is estimated at $14.2 million for 2018, $13.9 million for 2019, $13.5 million for 2020, $12.9 million for 2021, $12.4 million for 2022 and $12.2 million for 2023. Purchased intangible amortization was $3.4 million, $2.5 million after tax, and $2.6 million, $1.7 million after tax, for the three months ended September 30, 2018 and 2017, respectively and $10.0 million, $7.5 million after tax, and $7.2 million, $4.7 million after tax, for the nine months ended September 30, 2018 and 2017, respectively. In addition to the above amortization, the Company recorded amortization expense associated with capitalized software of $8.2 million and $7.7 million for the three months ended September 30, 2018 and 2017, respectively and $24.7 million and $22.9 million for the nine months ended September 30, 2018 and 2017, respectively. Revenue Recognition Product revenue is recognized from contracts with customers when a customer has obtained control of a product. The Company considers control to have transferred upon shipping terms. To the extent the Company’s contracts have a separate performance obligation, revenue related to any post-shipment performance obligation is deferred until completed. Shipping and handling costs charged to customers are included in total net sales and the associated expense is a component of cost of sales. Certain products are also sold through indirect distribution channels whereby the distributor assumes any further obligations to the end customer. Revenue is recognized on these distributor arrangements upon transfer of control to the distributor. Contracts do not contain variable pricing arrangements that are retrospective, except for rebate programs. Rebates are estimated based on expected sales volumes and offset against revenue at the time such revenue is recognized. 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. The provisions for estimated returns and rebates are immaterial to the consolidated financial statements. Certain of the Company’s product arrangements include separate performance obligations, primarily related to installation. Such performance obligations are accounted for separately when the deliverables have stand-alone value and the satisfaction of the undelivered performance obligations is probable and within the Company's control. The allocation of revenue between the performance obligations is based on the observable standalone selling prices at the time of the sale in accordance with a number of factors including service technician billing rates, time to install and geographic location. Software is generally not considered a distinct performance obligation with the exception of a few small software applications. The Company does not usually sell software products without the related hardware instrument as the software is embedded in the product. 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. Service revenue not under contract is recognized upon the completion of the service performed. Revenue from spare parts sold on a stand-alone basis is recognized when control is transferred to the customer, which is generally at the time of shipment or delivery. Revenue from service contracts is recognized ratably over the contract period using a time-based method. 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. 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 $4.3 million and $12.5 million of share-based compensation expense for the three and nine months ended September 30, 2018, respectively, compared to $4.0 million and $11.8 million for the corresponding periods in 2017. 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 On January 1, 2018 the Company retrospectively implemented ASU 2017-07 to ASC 715 "Compensation - Retirement Benefits," which requires the Company to report the non-service cost components of net periodic benefit cost (pension cost) in other charges (income), net. These amounts were previously reported in selling, general, and administrative, cost of sales and research and development in the consolidated statement of operations. Nonservice pension benefits were $1.6 million and $1.2 million for the three months ended September 30, 2018 and 2017, respectively, and $4.7 million and $3.1 million and for the nine months ended September 30, 2018 and 2017, respectively. In February 2016 and July 2018, the FASB issued ASU 2016-02 and ASU 2018-11 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. The Company is currently evaluating the impact of this guidance as well as the election of certain practical expedients available within the ASU. The Company has identified its significant leases by geography and by asset class and made progress in developing accounting policies and future processes to ensure an effective adoption of the new standard. The ASU will be effective beginning the first quarter of 2019 and the Company will adopt using a modified retrospective approach without adjusting comparative periods. In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income". The accounting update provided entities with guidance on how to reclassify certain stranded tax effects from accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act, which was a tax bill enacted by the U.S. government in December 2017. The new guidance is effective for the year beginning January 1, 2019 and the Company is still evaluating the impact on the financial statements.
