The COVID-19 pandemic negatively impacted the global economy, disrupted global supply chains and created significant volatility and disruption of global financial markets. In response, many countries implemented business closures and restrictions, stay-at-home and social distancing ordinances and similar measures to combat the pandemic, which significantly impacted global business and dramatically reduced demand for dental products and certain medical products in the second quarter of 2020. Demand increased in the second half of 2020 and continued throughout 2021 resulting in growth over the prior year.</span></p><p style="margin-bottom: 0; background: #FFFFFF"><span style="font-family: 'Times New Roman', 'serif'; font-size: 11.00pt"> </span></p><p style="margin-bottom: 0; background: #FFFFFF"><span style="color: #000000; font-family: 'Times New Roman', 'serif'; font-size: 11.00pt; background: #FFFFFF">Our consolidated financial statements reflect estimates and assumptions made by us that affect, among other things, our goodwill, long-lived asset and definite-lived intangible asset valuation; inventory valuation; equity investment valuation; assessment of the annual effective tax rate; valuation of deferred income taxes and income tax contingencies; the allowance for doubtful accounts; hedging activity; supplier rebates; measurement of compensation cost for certain share-based performance awards and cash bonus plans; and pension plan assumptions. Due to the significant uncertainty surrounding the future impact of COVID-19, our judgments regarding estimates and impairments could change in the future and may result in a material adverse effect on our financial condition and liquidity. However, the extent of the potential impact cannot be reasonably estimated at this time.</span></p>
