Assessor of insurance risks (7)
I believe the answer is:
actuary
'assessor of insurance risks' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for actuary that I've seen before include "One calculating risk for insurance companies" , "One assessing risk" , "Person using statistics to calculate insurance premiums" , "Statistical expert who advises insurance companies on risk" , "Expert in statistics who calculates insurance probabilities" .)
