(AIG) have reached a definitive agreement under which AIG will acquire American General, creating the leading insurance and financial services organization in the world. Concurrently, American General, AIG, and Prudential plc have reached an agreement that terminated our previously announced merger agreement with Prudential.

Coupled with this growth, we have also created superior value for our shareholders. In joining with AIG, American General's ability to build on these leading positions will be significantly enhanced, which will create even greater opportunity to produce superior returns for shareholders.

As we work toward completing this transaction, the contributions, teamwork, and commitment of our employees will play a key role in our future success.
