To this end, the SEC has upgraded three specific technology infrastructure items: the risk/return summary taxonomy, its previewer/viewer and an XBRL validator. The 2010 risk/return summary taxonomy has been updated from its 2008 release primarily with technical changes to enhance the rendering of XBRL-tagged documents. The 2010 taxonomy is accompanied by sample tagged documents, an architecture guide, and a rendering guide. The SEC’s previewer/viewer has been updated to support this new taxonomy and accordingly, mutual funds can now preview how their risk/return submissions will appear.
Lastly, the Edgar system has been updated so that the XBRL validator will now test the risk/return summary XBRL exhibits to ensure compliance with the requirements of the Edgar Filer Manual Chapter 6.
The SEC is now asking mutual funds, filing agents and software vendors to begin the process of tagging their risk/return summary information, submitting test filings to Edgar to validate their documents, and previewing the documents in the previewer to help prepare for the compliance date.
The regulator has also recently been championing the use of XBRL in other areas such as corporate actions and in establishing a single data standard in the mortgage backed securities (MBS) market. Mark Bolgiano, president and CEO of XBRL US, spoke about the idea of XBRL tagging in the asset backed securities (ABS) markets last month.
“XBRL US has developed a prototype dictionary of terms for residential mortgage backed securities (RMBS) which could be a starting point to a broader development of XBRL data in the ABS market,” he explained. Philip Moyer, XBRL US board member and CEO of Edgar Online, has been heading a team at the standards body to develop the XBRL dictionary for mortgage data, which Bolgiano indicated is now ready for use.
