State Street Global Advisors to Acquire Bank of Ireland Asset Management

State Street Global Advisors (SSgA), the investment management business of State Street Corporation (NYSE: STT), announced today that it has agreed to acquire Bank of Ireland Asset Management (BIAM) for consideration of approximately €57 million inclusive of estimated net assets of the business of €14 million.

Pending regulatory approvals and other closing conditions, the transaction is expected to close in the first quarter of 2011 or earlier. State Street expects the transaction to be slightly accretive to 2011 earnings, excluding one-time costs. Upon closing of the transaction, the BIAM operation in Dublin will transition to State Street Global Advisors Ireland Limited.

With approximately €26 billion in assets under management among more than 500 clients as of September 30, 2010, BIAM is a recognized leader in the Irish market offering a broad range of investment solutions to institutional investors and intermediaries including global fundamental equities, fixed income, cash, asset allocation, property and balanced funds. Upon closing of the transaction, more than 120 employees of BIAM are expected to join SSgA in Dublin.

"This acquisition enables SSgA to expand its range of investment capabilities to include active fundamental management,” said Scott Powers, president and chief executive officer of State Street Global Advisors. "As our clients look for more solutions-driven investment management strategies that span the risk spectrum, the addition of this team and capabilities will enhance our ability to deliver on these needs. Like SSgA, Bank of Ireland Asset Management’s investment philosophy is rooted in a disciplined, team-based approach and has a strong track record of excellent performance. We look forward to building on this track record and extending its capabilities to our global client base.”

With this acquisition, SSgA will add Dublin as its 10^th global investment center from which investment teams manage client assets. SSgA offers a broad range of investment solutions covering every major asset class, capitalization range, region and style.

Chris Johns, currently the interim chief executive officer and chief investment officer of BIAM will be named SSgA chief investment officer for fundamental active equity and will report to Rick Lacaille, SSgA’s global chief investment officer.

• changes in law or regulation that may adversely affect our clients’ or our counterparties’ business activities and the products or services that we sell, including additional or increased taxes or assessments, capital adequacy requirements and changes that expose us to risks related to compliance;
• financial market disruptions and the economic recession, whether in the U.S. or internationally, and monetary and other governmental actions, including regulation, taxes and fees, designed to address or otherwise be responsive to such disruptions and recession, including actions taken in the U.S. and internationally to address the financial and economic disruptions that began in 2007;
• increases in the volatility of, or declines in the levels of, our net interest revenue, changes in the composition of the assets on our consolidated balance sheet and the possibility that we may be required to change the manner in which we fund those assets;

• the liquidity of the U.S. and international securities markets, particularly the markets for fixed-income securities, and the liquidity requirements of our clients;
• the credit quality, credit agency ratings, and fair values of the securities in our investment securities portfolio, a deterioration or downgrade of which could lead to other-than-temporary impairment of the respective securities and the recognition of an impairment loss in our consolidated statement of income;
