Concentration of Credit Risk	15. Concentration of Credit Risk Financial instruments that potentially subject the Company to credit risk consist principally of cash and accounts receivable. For the three and six month periods ended June 30, 2023 and 2022, all service revenue was from one customer.

15. Concentration of Credit Risk

Financial instruments that potentially subject the Company to credit risk consist principally of cash and accounts receivable.

For the three and six month periods ended June 30, 2023 and 2022, all service revenue was from one customer. For the three and six month period ended June 30, 2023, there was no grant revenue and for the three and six month period ended June 30, 2022, all grant revenue was from one grantor.

The cash balance identified in the balance sheet is held in an account with a financial institution and insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000. At times, cash maintained on deposit may be in excess of FDIC limits.

In early March 2020, there was a global outbreak of COVID-19 that has resulted in significant changes in the global economy. While the Company has not experienced any disruptions to its business operations to date, these changes, including a potential economic downturn, and any potential resulting direct or indirect negative impact to the Company cannot be determined, however they could have a prospective material impact to the Company’s business, cash flows and liquidity.
