Actual amounts could differ from those estimated amounts. The severity, magnitude and duration, as well as the economic consequences of the coronavirus diseases 2019 (“COVID-19”) pandemic, are uncertain, rapidly changing, and difficult to predict. Therefore, the Company’s accounting estimates and assumptions may change over time in response to COVID-19 and may change materially in future periods.</span>The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted on March 27, 2020 in the U.S., and includes several provisions related to employment and income taxes, including provisions for the deferral of the employer portion of social security taxes through December 31, 2020. On December 27, 2020, the U.S. government enacted the Consolidated Appropriations Act, 2021, which enhances and expands certain provisions of the CARES Act. These legislative acts are not expected to have a material impact on the Company’s consolidated financial results.

During 2021, sales to the Company’s ten largest customers, including group purchasing organizations (“GPOs”), accounted for approximately 51% of its total consolidated revenues and approximately 32% of total trade accounts receivable at March 31, 2021. Sales to the Company’s largest customer, CVS Health Corporation (“CVS”), accounted for approximately 21% of its total consolidated revenues in 2021 and comprised approximately 19% of total trade accounts receivable at March 31, 2021. As a result, the Company’s sales and credit concentration is significant. The Company has agreements with GPOs, each of which functions as a purchasing agent on behalf of member hospitals, pharmacies and other healthcare providers, as well as with government entities and agencies. The accounts receivables balances are with individual members of the GPOs, and therefore no significant concentration of credit risk exists. A material default in payment, a material reduction in purchases from these or any other large customers, or the loss of a large customer or customer groups could have a material adverse impact on the Company’s financial condition, results of operations, and liquidity. In addition, trade receivables are subject to concentrations of credit risk with customers in the institutional, retail, and healthcare provider sectors, which can be affected by a downturn in the economy and changes in reimbursement policies. This credit risk is mitigated by the size and diversity of the Company’s customer base as well as its geographic dispersion.</span>
