Do we lose the cumulative bonus if we reduce the sum assured amount while renewing

[>take]

I do not even wish to change the company from whom I have bought the mediclaim policy. I had not taken a floater policy . I had taken individual mediclaim for my family within a single policy. I now wish to take a floater policy and so I asked my agent to reduce the sum assured while renewing so that the premium becomes less and so that I can take a floater policy. My agent says that if I reduce the sum assured while renewing I will lose the cumulative bonus. Is he right ?

Pls. let me know.

Can you please post scan copy of the statement what you agent is agreeing OR broucher of the policy OR any website link, that cought throw light on this?
