What is the calculation for goodwill in Topmaker's purchase of Rainer's common shares using the equity method?

Goodwill in Topmaker's purchase of Rainer's common shares using the equity method is calculated as $60 million. This is derived from the purchase price of $300 million minus the acquired equity in Rainer's net assets and the attributable difference between fair and book value of net identifiable assets.

The calculation of goodwill for Topmaker's purchase of Rainer's common shares using the equity method is as follows: The purchase price is $300 million. The acquired equity in the book value of Rainer's net assets is 15% of $1,340 million, which equals $201 million. The excess purchase price is then $99 million. From this, the attributable difference between fair and book value of net identifiable assets (specifically plant and equipment) is 15% of $260 million, amounting to $39 million. Therefore, the goodwill is calculated as $99 million minus $39 million, resulting in $60 million.
