CY2020	us-gaap	Use Of Estimates UseOfEstimates	The preparation of consolidated financial statements in conformity with U.S. Generally Accepted Accounting Principles (U.S. GAAP) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company’s results are affected by economic, political, legislative, regulatory and legal actions. Economic conditions, such as recessionary trends, inflation, interest and monetary exchange rates, government fiscal policies, government policies surrounding the containment of COVID-19 and changes in the prices of raw materials, can have a significant effect on operations. These factors and other events could cause actual results to differ from management's estimates.

Derivatives are recorded at fair value on the consolidated balance sheet, and gains and losses are recorded as adjustments to income or other comprehensive income, as appropriate. For derivative financial instruments that are designated as a hedge, unrealized gains and losses related to the effective portion are either recognized in income immediately to offset the realized gain or loss on the hedged item, or are deferred and reported as a component of other comprehensive income (loss) in shareholders' equity and subsequently recognized in net income when the hedged item affects net income.
