Towers Watson will have tremendous global reach and service breadth to meet the growing needs of the world’s largest multinational corporations. As we provide more value for our clients, we in turn create value for our people and our shareholders.”

Mark Mactas, Chief Executive Officer of Towers Perrin, said, “This is an important transaction for our respective organizations that positions us well for a future of accelerated growth and higher levels of profitability. The fit between our firms is excellent, starting with a deep commitment to client service and shared values of integrity, professionalism and respect. Our service lines and geographic strengths are also highly complementary, which creates great opportunities for growth. We couldn’t be more excited about this combination, which will change the landscape of our industry.”

Towers Watson, which is expected to have annual revenues in excess of $3 billion, will benefit from the scale of the combined companies and anticipates approximately $80 million in pretax annual synergies. While significant savings are expected during the first two years following completion of the transaction, it is anticipated that full realization of synergies will take three years and cost approximately $80 million. Towers Watson will also have significant non-cash expenses during the first two years following completion of the transaction. The transaction is expected to be accretive to diluted earnings per share within three years following the consummation of the transaction.

Strategic & Financial Benefits of the Transaction

• Strengthened Organizational Capabilities: Towers Watson will be stronger than the sum of its parts, positioned for industry leadership long into the future and a more effective competitor that can provide additional services to our existing and prospective clients.
• Expanded Global Presence with Geographically Diverse Revenue Base: The combination will expand our global footprint to optimize service, global reach, and seamless delivery for our clients. Towers Watson will operate within four geographic regions: North America, EMEA (Europe, Middle East and Africa), Asia-Pacific, and Latin America.
• Enhanced Products and Services: Towers Watson will focus its operations on three segments: Benefits, Talent and Rewards, and Risk and Financial Services. These will build on existing thought leadership and research, and will be supported by a more comprehensive set of services, from strategic advice to solutions and implementation.

We believe that these benefits will lead to:

• Increased Growth and Revenue: For our shareholders, we expect to deliver economies of scale, diversification of our current businesses, and increased growth and investment potential.
• Greater Depth of Talent for Our Clients: We expect to provide broader solutions and a deeper talent pool across a wider geographic footprint.
