The conditions outlined in
CIRD40520 do not require the transferor
and transferee company to have been members of the same group at
the time of the transfer. It is sufficient that they became members
subsequently.
As a result the degrouping rules can in principle apply to
cases where the transfer of the asset did not take place on
tax-neutral terms. Instead:
The degrouping calculation will not lead to any adjustment since the transferee company will be deemed to have realised the asset and reacquired it at the price already deemed to have been paid for it for the purposes of Schedule 29, namely market value.
If, as one would expect, the price agreed between the parties was market value then the consequences are as for cases within (a). It is in theory possible that the price was not market value but in practice that is highly unlikely. In the absence of exceptional circumstances you should accept that such transactions have taken place at market value.
These cases are on all fours with those where the transfer was given tax-neutral treatment under the group rules.
