Bear with me but here are some calculations based on the last 10K and recent PR's.
Since May 9th we have had contracts signed for 77 units. I'll call that about a month and a half of R&R work. So annualized that comes to 616 units.
According to their website the price breaks down like this:
$500 unit cost
$25 activation fee
$40 monthly recurring monitoring fee
Using 2005 figures the total operating expense was $3,022,448
So to cover ALL of the operating expenses for a year we would need to sell 3008 units. Now that's just for the first year, then the year after that they only need to sell 1571 units to break even because of the monthly recurring monitoring fee. And likewise they only need to sell 820 units the third year (assuming that all contracts stay in place that long).
According to the company website quantity discounts are available so my assumptions may be a little hokey, but it also states that contracts are either 24 or 36 months long.
Bottomline, if we add another two sales companies like R&R we could be talking about profitability within two years. And that doesn't even take into account the Karta deal that is pending.
