you get 1 vlassic share for every 10 you have of cpb. if you have 100 cpb shares, that means you get 10 vlassic shares. ir at cpb said vlassic priced at 22. so, if you have 10 shares at 22 that vulue is 220 dollars.
that (small ) amount is about the difference of what the cpb shares versus cpb when issued shares are currently priced, if you had 100 shares and lets say you paid 55 per share for them.
so, the when issued price must be the post spinn off price.
