BOSTON, Mass.--(BUSINESS WIRE)--Oct. 30, 2003--State Street Corporation (NYSE: STT), the world's leading specialist in meeting the needs of institutional investors, and DST Systems, a developer of proprietary software systems for shareholder accounting and recordkeeping services, today mark the 30 year anniversary of the formation of Boston Financial Data Services (BFDS).

Co-founded in 1973, BFDS is a leading provider of automated shareholder recordkeeping for mutual fund management companies. Over the past 30 years, BFDS has built its position as the largest mutual fund transfer agent in the United States, and today employs nearly 2,600 individuals and serves a client base of over 21 million shareholder accounts.

"State Street applauds BFDS' 30 years of growth, expansion and recognition as an established leader in the financial services marketplace," said Jay Hooley, executive vice president of State Street Corporation. "With the demand for quality shareholder services becoming more and more critical as investment products become increasingly complex, our clients value the unique relationship we have developed with BFDS.
