Mortgages taken back by a developer in order to facilitate sales may initially be assets used in an active business, but will become investments if retained for more than a short period.
Substantial amounts of cash and deposits in excess of those required for use of the business and that are retained on a permanent basis, will not be considered to be funds used in the business.
The only receivables considered to be assets used in an active business are trade accounts receivable that arise from sales in the course of the corporation's active business.
