On March 9, 2015, the EDGAR system was upgraded to Release 15.0.3 and now supports the US GAAP 2015 and 2015 EXCH taxonomies. The 2015 US GAAP financial reporting taxonomy reflects the same taxonomy that FASB made available on its website on December 18, 2014. The 2015 EXCH taxonomy reflects the same taxonomy the staff posted for public comment on September 2, 2014. The staff does not anticipate that the removal of the 2013 US GAAP financial reporting taxonomy and the 2013 EXCH taxonomy will occur before June 2015.
Please see http://www.sec.gov/info/edgar/edgartaxonomies.shtml for a complete listing of supported standard taxonomies.
The staff strongly encourages companies to use the most recent version of taxonomy releases for their XBRL exhibits to take advantage of the most up-to-date tags related to new accounting standards and other improvements. The staff suggests that filers consider transitioning to the 2015 taxonomies for the earliest reporting period that ends after March 9, 2015, but not for reporting periods that end before March 9, 2015.
