Business: Merrill Lynch & Co. Inc., Accelerated Return Notes linked to the Nikkei 225 Index (Index Symbol NKY), due 8/6/2008, and issued at $10 per unit. The notes will receive no payments before maturity, are not redeemable prior to maturity, and make no guarantee of the return of principal at maturity. At maturity the holder will receive a payment based on the percentage change in the Nikkei 225 Index, starting value 17,875.75 as of 5/31/2007. If the Index has increased, the maturity payment will be based on triple the percentage increase in the Nikkei 225 Index, not to exceed $12.685 per note. If the index has decreased, the holder will receive a payment based on the full percentage of decrease in the Index. As a result, the maturity payment may be less, and possibly significantly less, than the $10 offering price. See page PS-4 of the prospectus for further information on the calculation of the maturity payment and see page PS-5 for hypothetical examples of the maturity payment. The accelerated return notes are Medium Term Notes, Series C which are senior unsecured debt securities issued by Merrill Lynch & Co. Inc. and rank equally with all of their other unsecured and unsubordinated debt.
