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 expected credit losses represents the Company's best estimate based on historical information, current information, and reasonable and supportable forecasts of future events and circumstances.

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:


	March 31, 2022		December 31, 2021
Raw materials and parts	$	199,933	$	184,624
Work-in-progress	84,081		76,019
Finished goods	162,476		153,900
	$	446,490	$	414,543

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 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 to be benefited. 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 “Intangibles – Goodwill and Other” and ASC 360 “Property, Plant and Equipment.”

Other intangible assets consisted of the following:


	March 31, 2022						December 31, 2021

The Company recognized amortization expense associated with the above intangible assets of $6.8 million and $4.1 million for the three months ended March 31, 2022 and 2021, respectively. The annual aggregate amortization expense based on the current balance of other intangible assets is estimated at $26.3 million for 2022, $25.3 million for 2023, $23.1 million for 2024, $22.2 million for 2025, $20.0 million for 2026 and $18.6 million for 2027. Purchased intangible amortization was $6.6 million, $5.1 million after tax, and $3.8 million, $2.9 million after tax, for the three months ended March 31, 2022 and 2021, respectively.

In addition to the above amortization, the Company recorded amortization expense associated with capitalized software of $9.7 million and $9.8 million for the three months ended March 31, 2022 and 2021, 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 based upon shipping terms. To the extent the Company’s arrangements 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 related 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 stand-alone 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 generally does not 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.

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 comprehensive income with a corresponding offset to additional paid-in capital in the consolidated balance sheet. The Company recorded $4.5 million and $4.6 million of share-based compensation expense for the three months ended March 31, 2022 and 2021, respectively.

Research and Development

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

Business Combinations and Asset Acquisitions

The Company accounts for business acquisitions under the accounting standards for business combinations utilizing the acquisition method of accounting. The results of each acquisition are included in the Company's consolidated results as of the acquisition date. The purchase price of an acquisition is allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values and any consideration in excess of the net assets acquired is recognized as goodwill. The determination of the values of the acquired assets and assumed liabilities, including goodwill and intangible assets, require significant judgement. Acquisition transaction costs are expensed when incurred.

In circumstances where an acquisition involves a contingent consideration arrangement, the Company recognizes a liability equal to the fair value of the expected contingent payments as of the acquisition date. Subsequent changes in the fair value of the contingent consideration are recorded to other charges (income), net.

Recent Accounting Pronouncements

In March 2020 and January 2021, the FASB issued ASU 2020-04 and ASU 2021-01: Reference Rate Reform, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by the discontinuance of LIBOR or another referenced rate. The guidance may be applied to any applicable contract entered into before December 31, 2022. The Company's interest rate and cross currency swaps, as mentioned in Note 4 to the consolidated financial statements, are governed by International Swaps and Derivatives Association (ISDA) agreements, and the Company will adhere to the ISDA's fallback protocol when LIBOR is discontinued. In addition, the Company renewed the LIBOR-based credit agreement, as discussed further in Note 10 of the Annual Report Form 10-K, which includes a fallback protocol when LIBOR is discontinued. Based on these procedures, when LIBOR is discontinued, the interest rate and cross currency swaps will not require de-designation if certain criteria are met. The Company expects the financial impact of the rate change when LIBOR is discontinued to be immaterial to its financial statements.
