The complaint charges BankUnited and certain of its officers and directors with violations of the Securities Exchange Act of 1934. The complaint alleges that during the Class Period, defendants made materially false and misleading statements regarding the Company including that: (a) the true risk associated with investing in the Company, given its undisclosed lack of underwriting standards; (b) the Company's true exposure to losses related to its sale of billions of dollars of pay-option arms, which were sold to unqualified borrowers at rates that were allowed to be set at artificially low levels; (c) BankUnited had adopted inadequate appraisal process and procedures, the purpose and effect of which was to qualify borrowers for over-valued mortgages; and (d) other illegal and improper practices related to the purchase and sale of subprime and nonprime mortgages. When the true impaired condition of the Company was ultimately made known to investors, shares of the Company collapsed and shareholders were damaged.

If you wish to serve as lead plaintiff in this class action lawsuit, you must move the Court no later than November 17, 2008. Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member.
