SFAS No. 160
In December 2007, the FASB issued FASB Statement No. 160, Non-controlling Interests in Consolidated Financial Statements, an amendment of ARB No. 51 (SFAS 160), that establishes new accounting and reporting standards for the non-controlling interest in a subsidiary and for the deconsolidation of a subsidiary. SFAS 160 requires the recognition of a non-controlling interest (minority interest) as equity in the consolidated financial statements and separate from the parents equity. The amount of net income attributable to the non-controlling interest will be included in consolidated net income on the face of the income statement. Certain changes in a parents ownership interest are to be accounted for as equity transactions and when a subsidiary is deconsolidated, any non-controlling equity investment in the former subsidiary is to be initially measured at fair value. SFAS 160 also includes expanded disclosure requirements regarding the interests of the parent and its non-controlling interest and is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. Our income statement and balance sheet disclosure will be changed by the application of SFAS 160, due to the reclassification of minority interest.
