CHICAGO, April 27 -- R.R. Donnelley & Sons Company announced today that the company will appoint Thomas J. Quinlan, III as its interim Chief Financial Officer, effective May 11, 2006. Mr. Quinlan will replace Glenn R. Richter, who will become Chief Administrative Officer of Nuveen Investments. Mr. Richter will remain with RR Donnelley to complete the first quarter financial reporting requirements and to ensure an orderly transition. RR Donnelley intends to name a permanent Chief Financial Officer following an appropriate process. Mr. Quinlan, who also will continue as Executive Vice President, Operations, has been with RR Donnelley and its predecessor companies since 2000, serving in executive management positions in finance and operations, including EVP, Treasurer from December 2000 until December 2002. Mr. Quinlan has been primarily responsible for the integration of RR Donnelley and Moore Wallace and the earlier integration of Moore Corporation Limited and Wallace Computer Services. He served previously in senior finance positions at World Color Press and Walter Industries. He holds an MBA in finance from St. John's University and a Bachelor of Science in finance from Pace University. "Tom Quinlan is a seasoned financial executive who is intimately familiar with our business and who brings fine leadership skills to this new role," said Mark A. Angelson, RR Donnelley's Chief Executive Officer. "I wish Glenn Richter well as he pursues his new opportunity." The company expects its first quarter 2006 non-GAAP earnings per fully diluted share will be $0.55 to $0.57 and also reaffirms its previously announced earnings guidance for the full year of 2006. The company will discuss its first quarter results on its scheduled earnings conference call on May 2. The company believes that certain non-GAAP measures, when presented in conjunction with comparable GAAP (Generally Accepted Accounting Principles) measures, are useful because that information is an appropriate measure for evaluating the company's operating performance. Internally, the company uses this non-GAAP information as an indicator of business performance, and evaluates management's effectiveness with specific reference to these indicators. These measures should be considered in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. Non-GAAP net earnings exclude restructuring and impairment charges and the results of discontinued operations in the first quarter of 2006. A reconciliation of GAAP net earnings per fully diluted share to non-GAAP net earnings per fully diluted share for these adjustments is presented in the attached table.
