Hi stlamc,
Assuming that TIX is priced fairly by the market based on a dividend yield alone (overly simplistic I know) you could assume that this increase in dividend should re-price the share to $2.47 to keep the yield the same:
18.6c @ $2.30 SP = 8.08% yield
20.0c @ 8.08 yield = $2.47 SP
Cheers
John
