Under ASU 2011-10, when a parent ceases to have a controlling financial interest in a subsidiary that is in substance real estate as a result of default on the subsidiary’s nonrecourse debt, the reporting entity would continue to include the real estate, debt and results of the subsidiary’s operations in its consolidated financial statements until legal title to the real estate is transferred to legally satisfy the debt.

Adoption is not anticipated to have a significant effect on our earnings or financial position but may result in certain additional disclosures. ASU 2012-02– Intangibles-Goodwill and Other will be effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The amendment provides entities with the option to make a qualitative assessment about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it should perform a quantitative impairment test, which is equivalent to the impairment testing requirements for other long-lived assets.
