Start bowling financial arrangements (9)
I believe the answer is:
rollovers
'financial arrangements' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'start bowling' is the wordplay.
I cannot quite see how this works, but
'bowling' could be 'over' (cricket term) and 'over' is found within the answer.
The remaining letters 'rolls' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for rollovers that I've seen before include "They make for a bigger pool" , "extensions to prize fund" .)
