The document discusses the benefits and requirements of XBRL (eXtensible Business Reporting Language) filing for public companies. It notes that the SEC now requires public companies to tag financial reports with XBRL by 2011. There are three main options for companies to file in XBRL: outsource tagging, use independent software, or integrate a software solution. The document recommends an integrated software solution as it can automate tagging, reduce filing time by 30%, and provide long term benefits by linking tags to source data and facilitating reporting across systems.
