I'm not going to be able to define and describe "profit" in anything less than 30,000 words so the following is just a note to help you get a bit of a handle on what you're looking at.
The profit for the 6 months, referred to most often as the statutory profit, is probably best discerned from the "Income Statement" on Page 2 where the "profit" is presented at $411.2m. In an overview form that is the number you should consider as the profit.

The difference between that number ($411.2m) and the cash surplus or the "net increase in cash and cash equivalents" ($28.7m) is due to the fact that some cash was spent on items that oughtn't be considered as having an impact on profit.

A rough reconciliation is as follows:


I hope this helps a little.
