On July 17, 2017, the EDGAR system was upgraded to Release 17.2 and no longer supports the 2015 US GAAP financial reporting taxonomy, the 2013 COUNTRY taxonomy, the 2014 CURRENCY taxonomy, or the 2015 EXCH taxonomy.

Please see https://www.sec.gov/info/edgar/edgartaxonomies.shtml for a complete listing of supported standard taxonomies.

The staff 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. On March 6, 2017, the EDGAR system was upgraded to Release 17.0.3 and now supports the 2017 US GAAP, 2017 COUNTRY, 2017 CURRENCY, 2017 EXCH, and 2017 NAICS taxonomies.
