Concentration of Credit Risk
7. CONCENTRATION OF CREDIT RISK

The Company maintains its cash balances primarily at one financial institution in a partially insured checking account that does not provide for interest. Instead, the account earns credits which offset banking fees.

Accounts receivable are financial instruments that also expose the Company to concentration of credit risk. The large number of customers comprising the Company’s customer base and their dispersion across different geographic areas limits such exposure. In addition, the Company routinely assesses the financial strength of its customers and maintains an allowance for doubtful accounts that management believes will adequately provide for credit losses.
