The full extent to which the COVID-19 pandemic will directly or indirectly have a negative material impact on the Company's financial condition, liquidity, or results of operations, is highly uncertain and difficult to predict. More specifically, the demand for the Company's products has been, and continues to be, affected by social distancing guidelines, newly implemented dental practice safety protocols which reduce patient traffic, and patient reluctance to seek dental care. At this time, it is uncertain how long these impacts will continue. </span></div><div style="text-align:justify;text-indent:18pt"><span><br/></span></div><div style="text-align:justify;text-indent:16.2pt"><span style="color:#222222;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">During the year the Company's business was impacted by COVID-19.

Many of these measures have been eased during the second half of the year as demand for the Company's products has improved. The Company continues to monitor the COVID-19 pandemic and may need to reduce operations in the event of a resurgence of COVID-19 or in the event of actions from governmental authorities to combat a resurgence. The Company believes it will be able to generate sufficient liquidity to satisfy its obligations and remain in compliance with the Company's existing debt covenants for the next twelve months.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify;text-indent:16.2pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">At December 31, 2020, the Company's liquidity includes $438 million of cash and has access to a $700 million 2018 Credit Facility as well as other short-term credit facilities of approximately $400 million. (See Note 13, Financing Arrangements). At December 31, 2020, the Company is in compliance with all of its debt covenants and expects to remain in compliance with all covenants for the next twelve months. However, if recovery from the pandemic takes longer than currently estimated, the Company may not be able to comply with its debt covenants and may have to seek covenant waivers. Inability to obtain debt covenant waivers may lead to default and acceleration of all of its outstanding debt, which could have a material adverse effect on liquidity.</span></div>
