Significant items subject to such estimates include the allowance for doubtful accounts based on the assessment of the collectability of customer accounts, the operating right-of-use assets and the associated lease liabilities, deferred revenues associated with unsatisfied performance obligations, accrued liability for potential refund requests, the valuation of the Convertible Notes, stock-based compensation and the related valuation of equity awards, income tax uncertainties, and the expected consideration to be received from contracts with customers. These estimates and assumptions are based on management's best estimates and judgment. Management regularly evaluates its estimates and assumptions using historical experience and other factors, including contractual terms and statutory limits; however, actual results could differ from these estimates and could have an adverse effect on the Company's financial statements.</p>

The extent of the impact of the COVID-19 pandemic on the Company's business is highly uncertain and difficult to predict, and the full extent and duration of the impact of the COVID 19 pandemic on our business, our operations, and the global economy as a whole is not yet known. While the Company’s test volumes as well as overall average selling prices increased in the year ended December 31, 2020 compared to the year ended December 31, 2019, the Company cannot predict the potential nature, magnitude and duration of the effects of the COVID-19 pandemic on the macroeconomic environment.</p><p style="background-color:#ffffff;font-family:'Times New Roman','Times','serif';font-size:10pt;padding-bottom:12pt;text-align:justify;text-indent:36pt;margin:0pt;">Financial instruments that potentially subject the Company to credit risk consist of cash, accounts receivable and investments. The Company limits its exposure to credit loss by placing its cash in financial institutions with high credit ratings. The Company's cash may consist of deposits held with banks that may at times exceed federally insured limits. The Company performs evaluations of the relative credit standing of these financial institutions and limits the amount of credit exposure with any one institution.</p><p style="background-color:#ffffff;font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">The Company performs evaluations of financial conditions for insurance carriers, patients, clinics and laboratory partners and generally does not require collateral to support credit sales. For the years ended December 31, 2020, 2019, and 2018, there were no customers exceeding 10% of total revenues on an individual basis. As of December 31, 2020 and 2019, there were no customers with an outstanding balance exceeding 10% of net accounts receivable.</p>
