Recent Accounting Pronouncements

In March 2013, the Financial Accounting Standards Board (“FASB”) issued guidance on a parent company’s accounting for the cumulative translation adjustment upon derecognition of a subsidiary or group of assets within a foreign entity. This new guidance requires that the parent release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The amendments became effective for the Company beginning January 1, 2014. The Company adopted this guidance and the adoption did not have any impact on the Company's financial statements.
