R. R. Donnelley & Sons Company (Nasdaq:RRD) announced today that it has been the first to support a mutual fund client by executing a live XBRL filing on its behalf. The documents were submitted under the "Interactive Data for Mutual Fund Risk/Return Summary" rule (Release No. 33-9006) using RR 2010 as the base taxonomy. The filing, on December 17, 2010, was for Russell Investments, a global financial services firm that serves institutional investors, financial advisers and individuals in more than 40 countries. It included Form 485BPOS with XBRL exhibit 101.

"In 2006 RR Donnelley was the first to file for a mutual fund under the voluntary XBRL filing program and we are proud to meet our clients' needs with this continuing innovation," stated John Paloian, the company's Chief Operating Officer. "The platform we've developed and the expertise we offer helps our clients achieve their compliance goals in financial centers around the world."

RR Donnelley's suite of XBRL services includes Risk/Return Summary, DFN and BFN template creation, EDGAR filings, tag guidance, project management, general ledger integration, technical consultation and more.

"Even as we integrate the exceptional resources and talent brought to RR Donnelley through our acquisition of Bowne & Co., we continue our pattern of leadership and innovation," said Daniel Knotts, RR Donnelley Group President.
