State Street Corporation is a provider of financial services to institutional investors including investment servicing, investment management, and investment research and trading.

According to a press release dated December 19, 2009, the Complaint charges State Street and certain of the Company’s executive officers with violations of federal securities laws. The Complaint alleges that throughout the Class Period, Defendants made false and/or misleading statements, as well as failed to disclose material adverse facts about the Company's business, operations and prospects. Specifically, Defendants made false and/or misleading statements and/or failed to disclose: (1) that the Company set up a scheme to substantially mark up foreign currency trades; (2) that such scheme caused State Street’s clients to overpay for such trades; (3) that the scheme allowed the Company to reap illegal profits; (4) that, as a result, the Company’s financial results were materially inflated; (5) that the Company's financial results were not prepared in accordance with Generally Accepted Accounting Principles; and (6), that the Company lacked adequate internal and financial controls.

On October 20, 2009, California Attorney General Edmund G. Brown Jr. announced that he had filed suit against State Street alleging the Company committed “unconscionable fraud” against California's two largest pension funds – California Public Employees’ Retirement System (“CalPERS”) and California State Teachers’ Retirement System (“CalSTRS”) – and “illegally overcharged CalPERS and CalSTRS for the costs of executing foreign currency trades since 2001.”

On this news, shares of State Street declined $4.41 per share, nearly 8.5%, to close on October 20, 2009, at $47.84 per share, on unusually heavy volume.
