CY2020	us-gaap	Use Of Estimates UseOfEstimates	<p style="font-family: Arial; font-size: 10pt; margin: 0pt; text-align: justify; text-indent: 18pt;"><b>Use of Estimates</b> – In preparing the consolidated financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP"), management must make decisions that impact the reported amounts of assets, liabilities, revenues, expenses and the related disclosures, including disclosures of contingent assets and liabilities. Such decisions include the selection of the appropriate accounting principles to be applied and the assumptions on which to base accounting estimates. Estimates are used in determining, among other items, sales promotions and incentives accruals, inventory valuation, warranty reserves, allowance for doubtful accounts, pension and postretirement accruals, useful lives for intangible assets, and future cash flows associated with impairment testing for goodwill and other long-lived assets. These estimates and assumptions are based on management’s best estimates and judgments. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors that management believes to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. A number of these factors include, among others, economic conditions, credit markets, foreign currency, commodity cost volatility and consumer spending and confidence, all of which have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual amounts could differ significantly from those estimated at the time the consolidated financial statements are prepared. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.</p> <p style="font-family: Arial; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"> </p>

The amount of the liability is based on the trend in the historical ratio of claims to sales, the historical length of time between the sale and resulting warranty claim, new product introductions and other factors. In the event we determine that our current or future product repair and replacement costs exceed our estimates, an adjustment to these reserves would be charged to earnings in the period such determination is made. Warranty terms on machines range from <span style="-sec-ix-hidden:c69525622">one</span> to <span style="-sec-ix-hidden:c69525623">four</span> years. However, the majority of our claims are paid out within the <em style="font: inherit;">first</em> <em style="font: inherit;">six</em> to <em style="font: inherit;">nine</em> months following a sale. The majority of the liability for estimated warranty claims represents amounts to be paid out in the near term for qualified warranty issues, with immaterial amounts reserved to be paid out for older equipment warranty issues. Warranty costs are recorded as a component of Selling and Administrative Expense in the Consolidated Statements of Operations.</p> <p style="font-family: Arial; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"> </p>
