Andrew Brown is the group accountant for P Ltd. P Ltd owns 60% of A Ltd which owns 70% of B Ltd. He has just completed the preparation of the consolidated financial statements of the group, and is discussing issues raised by the auditors. The auditors have raised concerns about the accounting for a dividend paid by B Ltd to A Ltd in the current period. They argue that further consolidation adjustments are necessary to avoid double-counting the non-controlling interest's share of equity. Andrew has asked for your advice concerning the effect of the payment of such a dividend on the determination of the non-controlling interest share of equity. Write a report to Andrew explaining the non-controlling interests that exist within the group, and how the calculation of their interests is affected by payment of dividends within the group.
