State Street yesterday said that federal regulators had subpoenaed additional trading information from some of its units, Reuters reports.

State Street – a custodian of $9.4 trillion, manager of $1.4 trillion and calculator of the bulk of mutual fund prices quoted in newspapers – said it has already cooperated with the SEC and the Department of Labor.

The financial services giant did not disclose what specific information or which units had been contacted. The Securities and Exchange Commission, along with about 15 states, are investigating market timing and late trading.
