The standard update provides that a liability related to an unrecognized tax benefit should be offset against same jurisdiction deferred tax assets for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. This guidance is effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013.

In March 2013, FASB issued ASU 2013-05, “Foreign Currency Matters (Topic 830); Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.” This guidance 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 business within a foreign entity. ASU No. 2013-05 is effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013. We will adopt this guidance beginning with our fiscal quarter ending December 31, 2014. We currently are reviewing the provisions of ASU No. 2013-05 but do not expect it to have an effect on our consolidated financial statements as we currently do not intend to sell any foreign entities for which we hold a controlling financial interest.
