On March 9, 2020, the EDGAR system was upgraded to Release 20.1.1 and now supports the 2020 U.S. GAAP, 2020 SEC Reporting (SRT), 2020 Countries (Country), 2020 Currencies (Currency), 2020 Exchanges (EXCH), and 2020 Standard Industrial Classification (SIC) taxonomies. The 2020 U.S. GAAP financial reporting taxonomy and the 2020 SEC Reporting Taxonomy reflect the same taxonomies that FASB made available on its website on December 20, 2019. The 2020 Country, 2020 Currency and 2020 EXCH, and 2020 SIC taxonomies reflect the same taxonomies the staff posted for public comment on September 9, 2019. Refer to the Release Notes for SEC Taxonomies 2020 for details of the changes (https://xbrl.sec.gov/doc/releasenotes-2020.pdf).

The EDGAR system no longer supports the 2013 and 2012 INVEST taxonomies. The staff does not anticipate that the removals of the 2018 U.S. GAAP, 2018 SRT, 2016 Country, 2017 Currency, or 2018 EXCH taxonomies will occur before June 2020.

Please see https://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 2020 taxonomies for the earliest reporting period that ends after March 9, 2020, but not for reporting periods that end before March 9, 2020.
