if a change in group structure (control -> no control, vice versa) happens within the financial year, how do we adjust for this for a consolidated SFP question? Most questions I see are disposals / acquisitions either at the year end or prior years, none are in the financial year.
In the SFP you are unlikely to see a full disposal as the subsidiary that has been disposed of will no longer be consolidated and so the assets/liabilities will no longer need to be included in the SFP. So the question would be a bit uneventful.
The only thing you would really need to do is to include the group profit/loss in the group retained earnings.
