Returns and surrenders (6)
I believe the answer is:
yields
This clue is a double definition.
'returns' is the first definition.
('yield' can be a synonym of 'return')
'surrenders' is the second definition.
(I've seen this before)
'and' is the link.
(Other definitions for yields that I've seen before include "Surrenders the crops" , "Gives in to the crops" , "Crops or dividends" , "financial returns" , "outputs" .)
