On October 30, 2013, in connection with the announced organizational realignment to consolidate activities within and across units, and reduce operating costs to mitigate core service revenue declines and cost inflation, the Company determined that, effective January 1, 2014, the position of President, North America, would be divided into two separate roles:  Executive Vice President, General Manager, Records and Information Management and Executive Vice President, General Manager, Data Management. Harry Ebbighausen will cease serving as President, North America as of such date. Effective January 1, 2014, Mr. Ebbighausen will begin serving in the newly created executive position of Executive Vice President, General Manager, Emerging Businesses to provide a more discrete focus on the identification, evaluation and launch of new businesses related to the Company’s core activities.

Beginning January 1, 2014, John Tomovcsik, who currently serves as the Company’s Executive Vice President and Chief Operating Officer, North America and has been with the Company for more than 27 years, will assume the position of Executive Vice President, General Manager, Records and Information Management.
