NOTE 12—CONCENTRATIONS

No individual customer represented more than 10% of the Company’s revenue for the three and six months ended June 30, 2023 or 2022.

The Company maintains its cash and cash equivalents in money market investment accounts with established commercial banks. Such cash deposits periodically exceed the Federal Deposit Insurance Corporation insured limit.

No individual customer represented more than 10% of the Company’s accounts receivable at June 30, 2023. As of December 31, 2022 accounts receivable from one customer totaled approximately 12% of total gross accounts receivable. The entire balance was either current or outstanding for less than 30 days.

The Company currently purchases certain key components of its products from single suppliers. Although there are a limited number of manufacturers of these key components, management believes that other suppliers could provide similar key components on comparable terms. A change in suppliers, however, could cause delays in manufacturing and a possible loss of sales, which could adversely affect the Company’s business, results of operations and financial condition.
