On 1 January four years ago, Freddie acquired 80% of the shares of Mercury for $500,000. Mercury had share capital of $100,000 (nominal $1 each) and had reserves of $200,000. No shares have been issued since acquisition. At acquisition, the fair value of the net assets was $320,000. The fair value adjustment related to inventory, that was sold immediately after the acquisition.
Goodwill has been tested for impairment at each year end since acquisition. No goodwill has been impaired since then. It is the group’s policy to value the non-controlling interest at fair value which at acquisition was $103,000.
