There is detailed guidance at
BIM38260 onwards.
A company may avail itself of a number of different types of
professional and financial services (whether bought in or
undertaken by the company's own staff) in the course of making or
defending a takeover bid. The costs may be charged under a number
of different heads in the accounts. For example:
Even where bid defence costs are identified separately in the
annual report it is still worth considering whether everything has
been included.
You should critically examine claims that the costs are
deductible in the light of the legal principles at
BIM42101 - BIM42105 (trading companies)
and CTM08350 (investment companies).
You will need to undertake detailed and comprehensive fact
gathering, and the application of the legal principles to the
particular facts can be complex.
