(11) CONCENTRATION OF CREDIT RISK Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of marketable securities. The Company maintains its investments in four difference brokerage accounts, all of which are insured by Securities Investor Protection Corporation (SIPC). The limits of this insurance are up to $100,000 for the total amount of cash on deposit with each Broker, and up to $500,000 for the total amount of securities held by each Broker. Each of these brokerage houses is well known in the industry and management does not believe that these securities bear any risk of loss over and above the basic risk that a security bears through the normal activity of the securities markets. However, as at December 31, 2005, the fair market value of securities in excess of the SIPC insured limit is $57,246,006, while there is no cash on deposit in excess of the insured limit.
