Segment Reporting [Abstract]

Segment Reporting

14.Segment Reporting

Operating segments are components of an enterprise that engage in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker ("CODM") in deciding how to allocate resources and assess performance. Our Chief Executive Officer ("CEO") has been identified as the CODM.

The Company views its operations, makes decisions regarding how to allocate resources and manages its business as one operating segment and one reportable segment. Our CODM evaluates financial information on a consolidated basis. As a result, the required financial segment information can be found in the consolidated condensed financial statements of the Company disclosed herein.

The following table represents the Company’s total revenue by geographic area (based on the location of the customer):

Concentrations of Credit Risk and Significant Customers

Financial instruments that subject the Company to significant concentrations of credit risk primarily consist of cash and cash equivalents, marketable securities and accounts receivable. Per the Company’s investment policy, cash equivalents and marketable securities are invested in financial instruments with high credit ratings and credit exposure to any one issue, issuer (with the exception of U.S. Treasury obligations) and type of instrument is limited. At September 30, 2023 and December 31, 2022, the Company had no investments associated with foreign exchange contracts, options contracts or other foreign hedging arrangements.

Concentration of credit risk with respect to accounts receivable is limited to customers to whom the Company makes significant sales. While a reserve for the potential write-off of accounts receivable is maintained, the Company has not written off any significant accounts to date. To control credit risk, the Company performs regular credit evaluations of its customers’ financial condition.

There was no revenue from customers that represented 10% or more of the Company's total revenue for the three and nine months ended September 30, 2023 and 2022.

No accounts receivable balance from a specific customer represented 10% or more of the Company's total trade accounts receivable at September 30, 2023. Significant accounts receivable balances representing 10% or more of the Company's accounts receivable and royalties at December 31, 2022 came from our accounts receivable balance outstanding with Purolite, an Ecolab Inc. company, which was 12.7% of our total trade accounts receivable balance.
