"2006 marked the successful completion of Wolters Kluwer's transformation to deliver sustainable growth and long-term shareholder value. In 2006, Wolters Kluwer continued to achieve strong financial results, consistent with the plans and targets we set for the year. Our revenues grew by 9%, including organic growth of 3%, demonstrating clear momentum behind our efforts to invest in expanding our leading market positions. Electronic product revenues increased significantly, to 43% of total revenues. This growth occurred across all divisions, highlighting the importance of integrated content and software solutions to our overall growth program.

"Wolters Kluwer's operating margins also improved as we realized significant savings resulting from operating efficiencies. This focus on efficiencies is continuing as we actively undertake operational excellence initiatives across the organization.

"With increased free cash flow, we have the financial resources to drive growth as well as return value to our shareholders. Reflecting the strength of these financial results, the company has proposed to increase the dividend by 5% for 2006.

"As we focus on 2007, we will accelerate profitable growth through rigorous execution of our strategy, which includes growing our leading positions, capturing key adjacent markets, exploiting global scale and scope, and continuing to institutionalize operational excellence. This strategy leverages our strength in superior content and technology, deep customer relationships, and market-leading brands.

"Looking forward, I have confidence in our ability to accelerate profitable growth, supporting enhanced shareholder value. It is a very exciting time to be at Wolters Kluwer," said McKinstry.
