The Securities and Exchange Commission (the Commission) is adopting revisions to the Electronic Data Gathering, Analysis, and Retrieval System (EDGAR) Filer Manual and related rules to reflect updates to the EDGAR system. The updates are being made primarily to support the 2015 US GAAP financial reporting and 2015 EXCH taxonomies; add new form types for registration of Security-based swap data repositories (SDR); revise the Form ID Application Confirmation screen; remove references to the Paper Form ID; and revise Item 1 on submission form type MA-A. The EDGAR system was upgraded to support the new 2015 taxonomies and revised MA-A form functionalities on March 9, 2015. The EDGAR system is scheduled to be upgraded to support the other functionalities on April 13, 2015.
