Wolters Kluwer Announces New Single Brand for U.S.-Based Legal Publishing, Workflow Solutions Businesses

(AMSTERDAM AND NEW YORK, January 17, 2006) – Wolters Kluwer announced today that its leading legal and compliance businesses Aspen Publishers, CCH, Kluwer Law International and Loislaw, are aligning under the new brand name Wolters Kluwer Law & Business in serving the legal professional, legal academic, hospital and business compliance markets.

Effective January 17, 2006, Aspen, CCH (law and business compliance products), Kluwer Law International and Loislaw will begin to go to market aligned with a new Wolters Kluwer Law & Business brand name and logo. The well-known names of each of these businesses will also continue to exist, representing product lines offered by Wolters Kluwer Law & Business.

New Brand Builds on Integrated Solutions Strategy

The new Wolters Kluwer Law & Business identity represents the next logical step in maximizing the capabilities of Wolters Kluwer’s prominent legal and compliance businesses serving the legal, professional and education markets. The units having been working together closely since 2004, focused on meeting the legal and business compliance needs of professionals in specialty areas.

“Our customers have already seen some of the benefits of our ability to leverage our rich content resources and product and technology investments across these businesses to focus completely on their needs,” said Robert Becker, CEO of Wolters Kluwer Law & Business. “By working together with a sharp focus on best serving legal and business compliance professionals, Aspen and CCH launched a series of very popular integrated online libraries in 2004 and 2005. Now, as we completely align our businesses under the single Wolters Kluwer Law & Business banner, we can further these types of integrated initiatives across our key markets and in new, promising niche practice areas where we can add distinct value for our customers.”

Along with the unified identity will be adoption of a single new logo, replacing the separate logos and word marks used previously by the different businesses. The new logo clearly identifies Law & Business as part of Wolters Kluwer, a leading multinational information services company serving professionals worldwide.

Business Names Retained as Product Lines

Aspen , CCH, Kluwer Law International and Loislaw will continue to exist as product brands offered by Wolters Kluwer Law & Business. As such, the law and business compliance products from CCH INCORPORATED, for example, will continue to carry the CCH name as a product name, but the product will be offered by Wolters Kluwer Law & Business.

CCH products that serve tax and accounting professionals will carry the name CCH, a Wolters Kluwer business — the new identity adopted by Wolters Kluwer for its business serving the tax and accounting markets.

Transitioning to New Brand Identity

“As we move ahead, legal and compliance professionals will come to know Wolters Kluwer Law & Business as the single source for in-depth, premiere specialized content and workflow solutions,” said Becker.

Wolters Kluwer Law & Business expects the full transition to the new name to be complete in 2007.

Wolters Kluwer Law & Business has over 1,000 employees and is based in New York City and Riverwoods, Ill. Other locations include Cambridge, Mass., Van Buren, Ark. and The Hague (Netherlands).
