Derivative Instruments and Hedging Activities Disclosure [Text Block]	10. Hedge Accounting and Hedging Programs We recognize all derivative instruments as either assets or liabilities in our Consolidated Balance Sheets and measure them at fair value. Gains and losses resulting from changes in fair value are accounted for depending on the use of the derivative and whether it is designated and qualifies for hedge accounting. We evaluate hedge effectiveness on our hedges that are designated and qualify for hedge accounting at the inception of the hedge prospectively, as well as retrospectively, and record any ineffective portion of the hedging instruments along with the time value of purchased contracts in the same line item of the income statement as the item being hedged on our Consolidated Statements of Income. Our hedging policy establishes maximum limits for each counterparty to mitigate any concentration of risk. Balance Sheet Hedging Hedges of Foreign Currency Assets and Liabilities We hedge our net recognized foreign currency denominated assets and liabilities with foreign exchange forward contracts to reduce the risk that the value of these assets and liabilities will be adversely affected by changes in exchange rates. These contracts hedge assets and liabilities that are denominated in foreign currencies and are carried at fair value as either assets or liabilities on the Consolidated Balance Sheets with changes in the fair value recorded to Net Foreign Currency Transaction Gain (Loss) in our Consolidated Statements of Income. These contracts do not March 31, 2021 December 31, 2020 not Cash Flow Hedging Hedges of Forecasted Foreign Currency Transactions In countries outside the U.S., we transact business in U.S. dollars and in various other currencies.

Fair Value Disclosures [Text Block]	11. Estimates of fair value for financial assets and financial liabilities are based on the framework established in the accounting guidance for fair value measurements. The framework defines fair value, provides guidance for measuring fair value and requires certain disclosures. The framework discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow) and the cost approach (cost to replace the service capacity of an asset or replacement cost). The framework utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three three • Level 1: • Level 2: not • Level 3: Our population of assets and liabilities subject to fair value measurements at March 31, 2021 Fair Value Level 1 Level 2 Level 3 Assets: Foreign currency forward exchange contracts $ 3.4 $ — $ 3.4 $ — Total Assets $ 3.4 $ — $ 3.4 $ — Liabilities: Foreign currency forward exchange contracts $ 17.5 $ — $ 17.5 $ — Total Liabilities $ 17.5 $ — $ 17.5 $ — Our population of assets and liabilities subject to fair value measurements at December 31, 2020 Fair Value Level 1 Level 2 Level 3 Assets: Foreign currency forward exchange contracts $ 3.0 $ — $ 3.0 $ — Total Assets $ 3.0 $ — $ 3.0 $ — Liabilities: Foreign currency forward exchange contracts $ 25.5 $ — $ 25.5 $ — Contingent consideration 1.8 — — 1.8 Total Liabilities $ 27.3 $ — $ 25.5 $ 1.8 Our foreign currency forward exchange contracts are valued using observable Level 2 10.

Actual results may may The carrying amounts reported in the Consolidated Balance Sheets for Cash and Cash Equivalents, Restricted Cash, Accounts Receivable, Other Current Assets, Accounts Payable and Other Current Liabilities approximate fair value due to their short-term nature. The fair value and carrying value of total debt, including current portion, were $320.3 million and $308.3 million, respectively, as of March 31, 2021 December 31, 2020 2
