The guidance requires that a parent deconsolidate a subsidiary or derecognize a group of assets that is a business if the parent ceases to have a controlling financial interest in that group of assets, and resolves the diversity in practice for the treatment of business combinations achieved in stages involving a foreign entity. The guidance is effective for annual and interim reporting periods beginning after December 15, 2013.
