Wolters Kluwer 2005 Annual Report publication

Amsterdam (March 27, 2006) – Wolters Kluwer, a leading multinational publisher and information services company, issued today its 2005 Annual Report both in print and online. The publication of the 2005 Annual Report also marks the official launch of the renewed corporate website, www.wolterskluwer.com supporting the new global identity of Wolters Kluwer and its strong brands under one ‘umbrella’ brand.

The 2005 Annual Report www.wolterskluwer.com/2005annualreport and the renewed company website www.wolterskluwer.com represent the new look and feel of Wolters Kluwer and the integration of Wolters Kluwer business units and their common culture of high quality content in context. The new site reflects the diversity of customers, products, services, tools and employees; and showcases Wolters Kluwer’s innovative solutions.

The Company’s strategy focuses on strengthening and transforming Wolters Kluwer in order to deliver sustainable growth and long-term shareholder value. Nancy McKinstry, CEO and Chairman of the Executive Board, commented in the Chairman’s Message, “As we begin 2006 and enter the third and final year of our plan, we are a stronger company. We have better market positions and product portfolios, more disciplined and streamlined operations, and greater capabilities at all levels of the organization. Our strong market positions and superior brands provide the foundation for further growth and increased scale efficiencies as we continue the transformation of Wolters Kluwer. Our vision is to always be The Professional’s First Choice.”

Renewed Corporate Website
Regular visitors of www.wolterskluwer.com will see a distinct difference, as the corporate website has been renewed to reflect Wolters Kluwer’s operational focus and new house style. The site now has a stronger focus on providing customer-oriented information.

Strong international collaboration between leading design, usability and development companies has resulted in a fully refreshed look, feel and functionality for the website. Designed by Landor Associates, an internationally recognized branding and design consultancy, the site was tested for user-friendliness by Jungle Rating, a market leader in the improvement of online channels. Digital spirit, a Wolters Kluwer business that focuses on providing interactive content solutions, and Investis, market-leading specialists in online corporate communications services, together delivered the design and functionality for the website itself.
