Yes, this is incorrect. Binder B incepted on 1 April 2004. So business will be written in that calendar year from 1 April to 31 Dec. So, this MUST be, on average, written in mid-August. You would not have scored marks for any other approach.
For subsequent years, we take note of the fact that the binding authorities are renewable annually. So business will be written throughout the year, and on average, will be written on 1 July.
So the solution is not inconsistent, it just shows that it's important to take note of the detail in the question.
This was a difficult question, but, put simply, we calculate the investment return by applying 4.5% of (net cashflow during the year/2 + claims reserve at the start of the year + UPR at the start of the year).
For a full description of this solution, I urge you again to use the ASET. I'm sure you'll find it very useful.
Good luck!
