In theory if everyone held the same shares and took the full allocation there is no impact, however it isn't a pro-rata issue. So it will depend person to person(those with a smaller holding now have greater potential to benefit, those that do not take the full benefit will be worse off).
What is more important is if you think the funds will be invested and utilised in the business for it to grow.
TGR has a great record of growth, and I am confident that they will use these funds to accelerate shareholder returns for 2017 onwards.
There will be a small dip, however upward trajectory we have been enjoying will continue !
