Work out how much your current shares have cost you, then divide that by the new number of shares you will have in TRIP, that will be your new break-even share price.
If you had 10,000 CPH shares @ 0.20 = $2,000
New TRIP holdings = 10,000 x 0.395 = 3,950 shares
$2,000 / 3,950 shares = $0.50c to break even, or your new "entry" price.
EDIT: Give or take 2 cents as conversion rates. Also not taking into consideration brokerage costs.
