Shares will remain exactly as they are now. Any new shares purchased going forward (if any) will be RIG shares.
Does this mean that if a person has 200 BFLS shares today, they would have 200 shares of 'BFLSSC' (or whatever it will be called) when the conversion to ASIC is done?
(For reference I'm using this:
https://bitcointalk.org/index.php?topic=89902.msg1455088#msg1455088)
i.e. a 200-share FPGA Single is converted to a 433-share SC Single (200/433 is the $600/$1300 price ratio). That is, the conversion would distribute
200 shares to the current shareholders and
233 shares to Inaba.
