Account incorporating information on company’s latest operation (6)
I believe the answer is:
agency
'operation' is the definition.
(thesaurus)
'account incorporating information on company's latest' is the wordplay.
'account' becomes 'ac' (abbreviation).
'incorporating' is an insertion indicator.
'information' becomes 'gen' (gen can informally mean information).
'on' means one lot of letters go next to another.
'latest' says to take the final letters.
The last letter of 'company' is 'y'.
'ac' enclosing 'gen' is 'agenc'.
'agenc'+'y'='AGENCY'
(Other definitions for agency that I've seen before include "Bureau; instrumentality" , "Business that works on behalf of another" , "Government unit - business providing services" , "Bureau finding jobs etc" , "Government office" .)
