Ann: Proposed return of 42 cents per share to shareholders, page-62

I plucked a number because it was an "example" with nice simple round numbers to keep it "simple".

The time this has taken to return the money to us is because a tax ruling was required to allow the company to return capital. This is portion is not considered profit by the tax office.

Capital return is a tax free portion, hence your cost base lowers by this amount.

You have been given an answer and if you are struggling with it get professional tax advice.
