Financial Instruments and Credit Risk Concentrations Disclosure [Text Block]

4.	Financial Instruments and Credit Risk Concentrations:
	Financial instruments that are potentially subject to concentrations of credit risk consist principally of marketable securities, cash and cash equivalents and receivables. Marketable securities and cash and cash equivalents are placed with multiple financial institutions and multiple instruments to minimize risk. No assurance can be made that such financial institutions and instruments will minimize all such risk.
	The Company derives rental income from fifty tenants, of which one tenant accounted for 19.29% and another tenant accounted for 15.60% of rental income during the six months ended January 31, 2013. No other tenant accounted for more than 10% of rental income during the same period.
	The Company has one irrevocable Letter of Credit totaling $230,000 at January 31, 2013 and July 31, 2012 provided by one tenant as a security deposit.
