On an ongoing basis, the Company evaluates its estimates, including those related to marketable investments, allowances for credit losses, standalone selling prices used to allocate revenue to performance obligations which are not directly observable, the amount of variable consideration included in the transaction price, warranty reserve, valuation of inventories, useful lives of property and equipment, operating and finance lease right-of-use (“ROU”) assets and liabilities, income taxes, contingent consideration and other contingencies, among others. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other data. Actual results could differ from those estimates.</span></div>

The majority of the Company’s cash is held by one financial institution in the U.S. in excess of federally insured limits. The Company maintained investments in money market funds that were not federally insured during the year ended December 31, 2020 and held cash in foreign entities of approximately $17.4 million and $17.3 million at December 31, 2020 and 2019, respectively, which was not federally insured. </span></div>The Company’s revenue has been derived from sales of its products in the United States and international markets. The Company uses both its own salesforce and independent distributors to sell its products. Concentrations of credit risk with respect to accounts receivable are limited due to the large number of entities comprising the Company’s customer base. The Company performs ongoing credit evaluations of its customers, including its distributors, does not require collateral, and maintains allowances for potential credit losses on customer accounts when deemed necessary.
