Where Does The Next Dividend Come From?, page-26

I cannot find any reference to the interim dividend being called special. In their chart it is just an interim dividend. So I dont agree with those that assert it as recorded as special.

I have seen the bar chart but the special dividends is solid grey and they were years ago. the shaded with diagonal lines is the anticipated final dividend for 2015.

I dont really know or follow how it got defined as special as its not that way in the latest reports.

If someone can give me an actual reference - date of announcement and name then I will look into it further.
