Just in time for the pending Securities and Exchange Commission mandate, an updated version of the digital dictionary companies will need to tag their financial statements in XBRL has been published.

XBRL US, the non-profit group responsible for maintaining the U.S. Generally Accepted Accounting Principles Taxonomies under contract with the SEC, has posted the 2009 release of the taxonomies.

The new release reflects industry changes and pronouncements by the Financial Accounting Standards Board incorporated since the 2008 release. The taxonomies will be updated annually.

Under the SEC’s XBRL mandate, roughly 500 of the largest domestic public companies—those with a worldwide public float of $5 billion or higher—must start submitting XBRL-formatted financial statements with their June 15, 2009, quarter. All other large accelerated filers must comply starting with their June 15, 2010, fiscal quarter, and all other public companies and foreign private issuers will comply starting with their June 15, 2011, fiscal quarter.

FASB pronouncements incorporated since the 2008 release include FAS No. 141 (R), Business Combinations; FAS No. 160, Non-controlling Interests in Consolidated Financial Statements—an amendment of ARB No. 51; FAS No. 161, Disclosures about Derivative Instruments and Hedging Activities—an amendment of FASB Statement No. 133; and FAS No. 163, Accounting for Financial Guarantee Insurance Contracts, an interpretation of FASB Statement No. 60.
