Concentrations of Credit Risk

11.   Concentrations
         of Credit Risk Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, accounts and trade receivables, and leases and mortgages receivable.  The Company maintains its cash and cash equivalents, including a money market account, at a large bank. At June 30, 2016, bank deposits exceeded Federal Deposit Insurance Corporation limits by approximately $3,400,000. Concentrations of credit risk with respect to trade receivables are limited due to a large customer base.  Also, based on the Company’s credit evaluation, trade receivables are often collateralized by the equipment sold. Sales to one customer accounted for approximately 12% of the Company’s revenues for fiscal 2016. Accounts and trade notes receivable due from two customers accounted for 18% and 15%, respectively, of the Company’s accounts and trade notes receivable at June 30, 2016.
