CME GROUP INC. 8-K Report, Corporate Update (Dec 4, 2008)

Filed December 4, 2008For Securities:CME

Summary

This 8-K filing from CME Group Inc. announces the furnishing of its third quarter 2008 financial statements, previously filed in its Form 10-Q on November 10, 2008, in XBRL (Extensible Business Reporting Language) format as Exhibit 100. This XBRL data is intended for technology testing purposes and is explicitly stated as unaudited. Investors are strongly advised to rely on the official, previously filed financial statements and not on the XBRL-formatted data for making investment decisions. The filing also includes associated XBRL taxonomy files. Importantly, the information furnished in this 8-K, including the XBRL data, is not considered 'filed' under Section 18 of the Securities Exchange Act of 1934. This means it does not carry the same legal liability as formally filed documents and will not be incorporated into other registration statements. The primary purpose appears to be a technical demonstration of XBRL capabilities.
