Merrill Lynch may make forward-looking statements, including, for example, statements about management expectations, strategic objectives, growth opportunities, business prospects, anticipated financial results, the impact of off balance sheet arrangements, significant contractual obligations, anticipated results of litigation and regulatory investigations and proceedings, and other similar matters. These forward-looking statements are not statements of historical facts and represent only Merrill Lynch’s beliefs regarding future performance, which is inherently uncertain. There are a variety of factors, many of which are beyond Merrill Lynch’s control, which affect its operations, performance, business strategy and results and could cause its actual results and experience to differ materially from the expectations and objectives expressed in any forward-looking statements. These factors include, but are not limited to, financial market volatility, actions and initiatives taken by both current and potential competitors, general economic conditions, the effects of current, pending and future legislation, regulation and regulatory actions, and the other risks and uncertainties detailed in Merrill Lynch’s Annual Report on Form 10-K for the fiscal year ended December 28, 2007 and subsequent reports on Form 10-Q and Form 8-K. Accordingly, readers are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date on which they are made. Merrill Lynch does not undertake to update forward-looking statements to reflect the impact of circumstances or events that arise after the date the forward-looking statements are made. The reader should, however, consult any further disclosures Merrill Lynch may make in its reports on Form 10-K, Form 10-Q and Form 8-K.
