Concentration of Credit Risk

5. Concentration of Credit Risk

       Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents and the interest rate swap. Although the Company deposits its cash with more than one financial institution, as of June 30, 2012, $39,081 of the cash balance of $56,804 was held at one financial institution. The Company has not experienced any losses on cash and cash equivalent accounts to date, and the Company believes that, based on the credit ratings of these financial institutions, it is not exposed to any significant credit risk related to cash at this time.

       The counterparty to the Company's interest rate swap is a major banking institution with a credit rating of investment grade or better and no collateral is required, and there are no significant risk concentrations. The Company believes the risk of incurring losses on derivative contracts related to credit risk is unlikely.
