12.Concentration of Credit Risk

Credit risk is the risk of loss from amounts owed by the financial counterparties. Credit risk can occur at multiple levels; as a result of broad economic conditions, challenges within specific sectors of the economy, or from issues affecting individual companies. Financial instruments that potentially subject the Company to credit risk consist of cash and accounts receivable.

The Company maintains cash with major financial institutions. The Company’s cash consists of bank deposits held with banks that, at times, exceed federally insured limits. The cash and cash equivalents also include short-term treasury bills with original maturities of three months or less. As of March 31,2023, the Company held deposits of $5,305, approximately $5,198 of which held by First Republic Bank (“FRB”). The Company’s deposits at FRB are largely uninsured. On May 1, 2023, JP Morgan Chase Bank (“JPM”) agreed to acquire all the assets and liabilities of FRB. Consequently, all depositors of FRB will become the depositors of JPM. Deposits at JPM are largely uninsured. The Company also invested in U.S. treasury bills in the amount of $37,663. The

Company limits its credit risk by dealing with counterparties that are considered to be of high credit quality and by performing periodic evaluations of the relative credit standing of these financial institutions.

Management periodically monitors the creditworthiness of its customers and believes that it has adequately provided for exposure to potential credit loss.
