Concentration of Risks

Concentration of Risks

Financial instruments that potentially expose the Company to concentrations of credit risk consist principally of cash and cash equivalents, short-term investments and accounts receivable. Cash is invested in accordance with the Company’s investment policy, which includes guidelines intended to minimize and diversify credit risk. Most of the Company’s investments are not federally insured. The Company has credit risk related to the collectability of its accounts receivable. The Company performs initial and ongoing evaluations of its customers’ credit history or financial position and generally extends credit on account without collateral. Additionally, the Company evaluates collectability risk over the life of its receivables in order to establish an appropriate reserve for certain receivables that may become uncollectible in future periods. The Company has not experienced significant credit losses to date. During the three and six months ended June 30, 2021 and 2020, the Company had no customers that individually represented more than 10% of total revenue. The Company had no customers that represented more than 10% of total accounts receivable as of June 30, 2021 or December 31, 2020.

The Company is also subject to supply chain risks related to the outsourcing of the manufacturing and production of its instruments to sole suppliers. Although there are a limited number of manufacturers for instruments of this type, the Company believes that other suppliers could provide similar products on comparable terms. Similarly, the Company sources certain raw materials used in the manufacture of consumables from sole suppliers. The impact of the COVID-19 global pandemic has not had a significant impact on the Company’s ability to source raw materials or its instruments to date. However, a change in or loss of suppliers could cause a delay in manufacturing and a possible loss of sales, which would adversely affect operating results. Should COVID-19 (or a variant thereof) continue to impact the global economy at the same or heightened levels during future periods, or if certain geographies where the Company’s key suppliers or manufacturing facilities are located are more severely impacted than others, this could negatively impact the Company’s ability to manufacture new products, fulfill customer orders, and collect from customers, which could adversely affect future operating results.
