Financial Instruments and Credit Risk Concentrations: |
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 forty-nine tenants, of which one tenant accounted for 17.17% and another tenant accounted for 14.00% of rental income during the nine months ended April 30, 2015. 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 April 30, 2015 and July 31, 2014 provided by a tenant as a security deposit.
