The primary focus of its investment strategy is to preserve capital and meet liquidity requirements. The Company's investment policy limits the amount of credit exposure with any one financial institution or commercial issuer. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company is exposed to credit risk in the event of default by the financial institutions holding its cash and cash equivalents to the extent recorded in the balance sheets. While the Company has not experienced any losses in such accounts and the Company has historically maintained its cash in multiple financial institutions, the recent failure of Silicon Valley Bank (“SVB”), at which the Company held cash and cash equivalents in multiple accounts, exposed the Company to limited credit risk prior to the completion by the Federal Deposit Insurance Corporation (“FDIC”) of the resolution of SVB in a manner that fully protected all depositors.</span></div>Concentrations of credit risk with respect to accounts receivable are primarily limited to certain customers to which the Company makes substantial sales. The Company's customer base consists of a large number of geographically dispersed customers diversified across several industries.
