A firm wants to takeover T firm, but management of T firm doesn't want to be acquired.

T firm currently has 1000 shares outstanding. T firm is using Poison Pill tactics: If any shareholders reaches 30% ownership, then any other shareholders with 1 share stock have rights to buy additional 2 shares at its 50% market value.

If a bidder reaches 30% ownership, what is the bidder's % ownership after shares dilution?
