“The 2012 Taxonomy contains updates for accounting standards and other improvements since the 2011 Taxonomy as used by issuers filing with the U.S. Securities and Exchange Commission (SEC). The Financial Accounting Standards Board issued proposed improvements to the taxonomy in the fall of 2011, allowing users of the taxonomy to provide feedback on the updates and the opportunity to become familiar with and to incorporate new element names for their filings. We encourage users to read the release notes and other provided guidance and supporting documents, which contain the details of these changes.”
