Satisfied to receive six - final bonus (8)
I believe the answer is:
dividend
'bonus' is the definition.
(dividend is a kind of bonus)
'satisfied to receive six final' is the wordplay.
'satisfied' becomes 'did' (doing is a kind of satisfying).
'to receive' means one lot of letters goes inside another.
'six' becomes 'vi' (roman numeral).
'final' becomes 'end' ('end' can be a synonym of 'final'**).
'did' placed around 'vi' is 'divid'.
'divid'+'end'='DIVIDEND'
(Other definitions for dividend that I've seen before include "Benefit from investment" , "Share of profit" , "Part of profits paid to shareholder" , "Return of profit" , "Part of profits distributed to shareholders" .)
