Talking Points for Chubb Managers

The following talking points are for use in meetings with members of your team to discuss the transaction with ACE Limited and the underlying rationale. We are also providing separate Employee Q&As on the transaction and on compensation and benefits. In addition, in the near future, ACE and Chubb will file a joint proxy statement/prospectus with the SEC. This document will provide extensive information about the transaction to shareholders of both companies in advance of their votes on the transaction. This proxy statement will be a publicly available document.


    As you know, Chubb has agreed to be acquired by ACE Limited for a premium of approximately 30% based on the closing price of Chubb and ACE shares on June 30th. This creates as of that date about $7 billion in increased value for Chubb shareholders, including employee shareholders.


    This is a compelling transaction that will combine two very successful companies with exceptional strengths in product, distribution, customer segments and underwriting cultures. We are convinced that the combined company will have enhanced growth and earnings power that Chubb could not achieve on its own.


    The combination of Chubb with ACE will better enable us to compete in the elite group of global P&C insurers – with greater financial strength, a stronger global presence, a wider range of product offerings and the critical scale to invest in the business. The combined company will have opportunities to grow in ways that might not otherwise be available to us as separate companies. As a combined enterprise, we will also have increased financial and talent resources, data and insight that, paired with our respective skills and experience, will drive profitable new growth opportunities in more markets around the world.


    As a combined company, we will have increased data and insight that, paired with our respective skills and experience, will drive profitable new growth opportunities in both developed and developing markets around the world.


    At a time when competitive conditions in our industry are changing and size and breadth are increasingly important to long-term success, this combination will elevate the two companies into an elite group of global P&C insurers – with a larger, stronger balance sheet, a stronger global presence, a wider range of product offerings and greater resources to invest in people, technology, products and distribution. We will also have a product mix that is less sensitive to the P&C pricing cycle.



    Importantly, the combined company will adopt the Chubb name – a clear indication of ACE’s respect for the Chubb brand and the attributes of quality and outstanding service it represents.


    In addition, after the transaction closes, our current Warren, New Jersey location will house a substantial portion of the headquarters function of the combined company’s North American Division.


    The transaction is expected to close in the first quarter of 2016. It will require approval by ACE and Chubb shareholders, as well as approval by various regulators.


    This transaction was not the result of a process initiated by our Board of Directors to sell Chubb. Rather, ACE approached us with a proposal that resulted in a substantial premium to our shareholders in a transaction that has a strong business and strategic logic. The Board evaluated the proposal thoroughly, with the assistance of outside financial advisors. The Board concluded that the proposed acquisition was in the best long-term interests of Chubb’s shareholders and its other constituencies and, consistent with the Board’s fiduciary duties, the Board approved the transaction.


    Chubb and ACE’s strengths in many areas complement each other, without significant overlap. Even where there is overlap in a particular market area, often we are focused on different segments within that market area. We believe that the complementary nature of our businesses will provide the combined company with greater growth opportunities, which in turn could lead to additional career opportunities in the combined organization.


    Of course, the transaction also contemplates the achievement of cost synergies in order to make the economics of the deal work. We will work with ACE in putting together an integration team with members from both companies which will develop an integration process, and that will take some time. Nevertheless, it is important to recognize that Chubb and ACE are each meritocracies and, to the extent that jobs overlap, it is our intention that the best people will be chosen to fill these jobs.


    We are committed to maintaining regular communication with all employees as we proceed toward the closing and the integration process plays out. We also are committed to ensuring that any employees that are impacted by the transaction are treated fairly.


    ACE’s CEO Evan Greenberg will be Chairman and CEO of the combined company. John Finnegan will be Executive Vice Chairman for External Affairs of North America and will assist with the integration and external matters.


    An integration team will be formed with representatives of senior management of both companies which in turn will determine the best organizational structure for the company going forward.


    You might receive inquiries from shareholders, analysts or reporters. It is essential that you not engage with them in any way. Direct any shareholder or analyst inquiries to Glenn Montgomery and any media inquiries to Mark Greenberg.



    Until the completion of the transaction, it’s business as usual, and both Chubb and ACE will continue to operate as separate and competing companies.


    During this transition period, it is especially important that we continue delivering the same level of service to our producers and policyholders for which Chubb is renowned.
