A group’s equity interest in a subsidiary increases when the parent, the subsidiary itself, or another subsidiary of the parent, purchases some or all of the shares held by a minority interest. When an accretion of equity interest is evidenced by a cash transaction and provided the price has been established at fair value, the accretion should be treated as an acquisition of additional equity interest, for which the acquisition principles prescribed in MASB ED #, Business Combinations should be applied. For example, a subsidiary’s repurchase of its own shares in the open market would normally satisfy the conditions for this treatment because a share repurchase would normally be in cash and the repurchase price would have been established at its fair market value. In other instances, the fair value condition would also be satisfied if the shares have been independently valued by professional valuers. In applying the acquisition principles for the increase in stake, the identifiable assets and liabilities acquired should be adjusted to their fair value, with the resulting difference being attributed to goodwill or negative goodwill. However, fair value adjustment is not required if the difference between fair value and book value is not material.
