Bank One Corporation provides services such as personal and corporate banking, business loans, investments, and credit cards.

The Complaint alleges that Defendants violated Sections 11 and 15 of the Securities Act of 1933; Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and Rule 10b-5 promulgated thereunder; and Section 206 of the Investment Advisers Act of 1940. The Complaint charges that, throughout the Class Period, Defendants failed to disclose that they improperly allowed certain hedge funds, such as Canary, to engage in "late trading" and "timing" of the Funds' securities. Late trades are trades received after 4:00 p.m. EST that are filled based on that day's net asset value, as opposed to being filled based on the next day's net asset value, which is the proper procedure under SEC regulations. Late trading allows favored investors to make use of market-moving information that only becomes available after 4:00 p.m. and has been compared to betting on a horse race that already has been run. Timing is excessive, arbitrage trading undertaken to turn a quick profit and which ordinary investors are told that the funds police. Late trading and timing injure ordinary mutual fund investors - who are not allowed to engage in such practices - and are acknowledged as improper practices by the Funds. In return for receiving extra fees from Canary and other favored investors, Bank One and its subsidiaries allowed and facilitated Canary's timing and late trading activities, to the detriment of class members, who paid, dollar for dollar, for Canary's improper profits. These practices were undisclosed in the prospectuses of the Funds, which falsely represented that the Funds actively police against timing and represented that post-4:00 p.m. EST trades will be priced based on the next day's net asset value and that premature redemptions will be assessed a charge.

In March 2004, by the Order from the Judicial Panel on Multidistrict Litigation, the case was transferred from the U.S. District Court for the Southern District of New York to the U.S. District Court for the District of Maryland.

According to the docket dated November 5, 2007, discovery proceeded in the multi-district mutual funds litigation. Simultaneously, some of the Defendants have been involved in settlement discussions with the Plaintiffs. This settlement process has been impacted by parallel regulatory proceedings occurring at the SEC. Nevertheless, the court has been advised that several settlements have been agreed upon in principle. Additionally, numerous individuals and firms have been voluntarily dismissed by Plaintiffs throughout 2005 and 2006. On June 11, 2007, the over-seeing judges issued a scheduling order calling for completion of discovery by March 28, 2008.
