Recently Adopted Accounting Pronouncements

In March 2013, the FASB issued updated authoritative guidance to resolve the diversity in practice about whether FASB Account Standards Codification (“ASC”) Subtopic 810-10, Consolidation—Overall, or ASC Subtopic 830-30, Foreign Currency Matters—Translation of Financial Statements, applies to the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) within a foreign entity. In addition, this guidance resolves the diversity in practice for the treatment of business combinations achieved in stages (sometimes also referred to as step acquisitions) involving a foreign entity.
