In UK, there are tax breaks for investors but not the tax break on strategic incentives along the lines that exists in India. The role of a corporate treasurer is to ensure that the money is available all the time and deployed correctly. The shareholders frown upon the corporate spending a lot of time and effort in managing the financial resources.

In general a corporate playing short-term investment games to boost returns is not liked by the investor. It will probably happen here too.

I don't think that the regulations would allow for a large corpus to be invested in equities but the pension money is very reliable, sensible money coming into equities that can rally in this long term.
