Notes to Financial Statements

Significant Accounting Policies [Text Block]

The accompanying unaudited condensed consolidated financial statements have been prepared on the basis of accounting principles generally accepted in the U.S. (“U.S. GAAP”). The preparation of financial statements in conformity with these accounting principles 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 periods. Significant estimates include acquisition purchase price allocations, the fair value of goodwill, the realization of deferred tax assets and liabilities, acquisition related liabilities, fair value of stock-based compensation for stock options granted, and assets and liabilities for pension and postretirement benefits. Actual results may ultimately differ from those estimates.

The condensed consolidated financial statements as of September 30, 2020 and for the three and nine months ended September 30, 2020 and 2019, in the opinion of management, include all adjustments, consisting of normal recurring items, to present fairly the Company’s financial position, results of operations and cash flows. The operating results for the three and nine months ended September 30, 2020 are not necessarily indicative of the results to be expected for the full year. The condensed consolidated financial statements and related notes as of and for the three and nine months ended September 30, 2020 have been prepared on the same basis as and should be read in conjunction with the annual report on Form 10-K for the year ended December 31, 2019. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules of the SEC. Certain reclassifications, including reflecting operating lease right-of-use assets, net, operating lease liabilities, and acquisition-related liabilities as a separate line item in 2019, have been made within the condensed consolidated statements of cash flows to conform to the respective 2020 presentation. The Company believes the disclosures made are adequate to keep the information presented from being misleading.

Recent Accounting Pronouncements

Accounting Standard	Description	Effective Date	Effect on Consolidated Financial Statements or Other Significant Matters
Financial Instruments—Credit Losses (Topic 326) In June 2016, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13, "Measurement of Credit Losses on Financial Instruments" ("Topic 326")	Topic 326 replaces the current “incurred loss” model for recognizing credit losses with an “expected loss” model referred to as the Current Expected Credit Loss ("CECL") model. Under the CECL model, an entity is required to present certain financial assets carried at amortized cost, such as trade receivables, at the net amount expected to be collected. The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This measurement takes place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the “incurred loss” model required under U.S. GAAP, which delays recognition until it is probable a loss has been incurred.	The Company adopted these amendments on January 1, 2020.	Refer to the accompanying condensed consolidated statements of changes in stockholders' equity for the adjustment of the opening retained earnings and Note 4. Fair Value Measurements for further discussions.
Reference Rate Reform (Topic 848) In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-04, "Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU No. 2020-04").	The amendment in this update provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendment in this update applies only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendment does not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship.	The amendment in this update is effective for all entities as of March 12, 2020 through December 31, 2022.	The Company adopted this amendment on March 12, 2020. There was no impact to the condensed consolidated financial statements as of and for the nine months ended September 30, 2020. The Company continues to monitor the transition of LIBOR to alternative reference rate measures that will likely become effective post December 2021.
