At home leaders of company under review suffer (5)
I believe the answer is:
incur
'suffer' is the definition.
(I've seen this before)
'at home leaders of company under review' is the wordplay.
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'leaders of' suggests taking the first letters.
The first letters of 'company under review' is 'cur'.
'in'+'cur'='INCUR'
(Other definitions for incur that I've seen before include "Arouse" , "Assume" , "Bring on oneself, say costs" , "Become subject to (eg, taxes)" , "Bring something unpleasant on oneself (5)" .)
