A unit of Prudential Financial sued State Street subsidiaries for over $80 million in losses ascribed to "undisclosed, highly leveraged" investments by State Street that included subprime mortgages. Prudential has said that State Street's management of the funds named in the lawsuit misrepresented their investment strategy and exposed them to undue risk.
What is Prudential's role? Prudential said the losses were suffered in accounts held by 28,000 individuals in 165 retirement plans it markets. These accounts held funds that were managed by State Street, of course a Boston bank and money manager. Prudential, a big insurer, has said that it will reimburse its clients for the $80 million they lost. Prudential said it had placed their clients in these two State Street Funds -- the Intermediate Bond Fund and the Government Credit Bond Fund -- and that the Boston money manager had marketed as investments that would provide "stable, predictable returns" in line with an index of U.S. government and corporate bonds.
What happened? Instead of that, the lawsuit alleges that State Street changed its investment strategy over the summer without notification and devoted a large portion of the funds' investments into financial instruments that included asset-based securities that over-whelmingly derived their value from home-equity loans, mortgage-backed securities swaps, derivatives and other exotic fare. The suit said that the bank recently informed Prudential it held a position in a synthetic index whose returns are linked to 20 subprime U.S. mortgage pools.
State Street has denied any wrongdoing and vows to vigorously fight, blaming the market. Let's see what happens.
