SF1 unit price has been lower than 50% of the unit price at the time of the offering (or under BTC0.0005) for the past four months and below BTC0.003 for the past 3 months, last price was BTC0.00015 so BTC0.00045 represents 3 times the latest price (this is also mentioned in the consultation poll announcement).
Not all SF1 unit holders have been holding SF1 units since the offering time, some transactions have been registered below BTC0.0001 per unit so for some unit holders getting BTC0.00045 per unit is a very good deal.
There are legal limitations to the number of shareholders and there is a cost for processing each shareholder's application, hence the minimum threshold to convert units into shares. However, trading will resume as of October 8th 12 noon time EST, anyone with an insufficient amount of units may buy more then.
If, following the results of the poll, we decided to make an offer, we will motivate it in more details then. It is just a consultation for now.
