The Company evaluates these estimates and assumptions on an ongoing basis based on current and historical developments, market conditions, industry trends and other information that the Company believes to be reasonable under the circumstances. The Company can make no assurance that actual results will conform to its estimates and assumptions; reported results of operations may be materially affected by changes in these estimates and assumptions.</span></div>While the Company did not incur significant operational or financial disruptions during the three months ended March 31, 2020, as a result of the COVID-19 pandemic, the Company may reevaluate certain of these estimates and assumptions in future periods which could result in material changes to its results of operations including, but not limited to, higher losses and loss adjustment expenses, lower premium volume, asset impairment charges, declines in investment valuations, reductions in audit premium estimates, deferred tax valuation allowances and increases in the allowance for expected credit losses related to available-for-sale securities, premiums receivable and reinsurance receivables. The extent to which the COVID-19 pandemic impacts the Company's business, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted. These factors include, but are not limited to, the duration, spread, severity, reemergence or mutation of the COVID-19 pandemic, the effects of the COVID-19 pandemic on the Company's insureds, the loss environment, the healthcare industry, the labor market and Lloyd's, the actions and stimulus measures taken by governments and governmental agencies, and to what extent normal economic and operating conditions can resume. Even after the COVID-19 pandemic has subsided, the Company may experience an impact to its business as a result of any economic recession tha
