gross potential revenue, page-8

In commercial real estate term a safe profit is capitalised at 8%, but one with a uncertain income flow but with further growth in say (Europe etc) the capitalisation may be 20% (particularly on a business) that equates to a PE ratio of 5

PE of 5? lol. ASX200 average PE is over 12 and most of these are low-growth companies. Fast growth young companies often trade at PEs of 30+. I used a conservative 20 which is reasonable for ISN and it's growth profile.

Regardless the price of $75 m is after fully developed with US approvals in place and sales rolling in and with potential in new markets like Europe.

Yeah with a PE of 5...lol. I can guarantee you if ISN turned around and said they had $25mill in sales, it would not be on a marketcap of $75mill.
