PS-3 RISK FACTORS You may not earn a return on your investment You should be aware that if LIBOR is outside of the Range during the applicable Range Period, you will not receive any interest payments on your Notes on the succeeding Interest Payment Date. The possibility exists that LIBOR will be outside of the applicable Range during each and every Range Period, in which case you would not receive any interest payments on your Notes and will only receive the Issue Price of $10,000 per Note at maturity. Therefore, although you have the opportunity to receive a return, you risk a lower return than comparable instruments, or no return at all. As such, the investment may not be suitable for persons unfamiliar with floating rate notes such as those based upon LIBOR, or unwilling or unable to bear the risks associated with an investment in the Notes. Investors should consult their advisers if in any doubt as to the nature of the investment and its suitability for them in the light of their particular circumstances. There may be an uncertain trading market for the Notes While there have been several issuances of ML&Co.'s Medium-Term Notes, Series B, upon issuance, your Notes will not have an established trading market. We cannot assure you that a trading market for your Notes will ever develop or be maintained if developed. The development of a trading market for the Notes will depend on our financial performance and other factors such as the change in the value of LIBOR. If the trading market for the Notes is limited, there may be a limited number of buyers for your Notes if you do not wish to hold your investment until maturity. This may affect the price you receive. UNITED STATES FEDERAL INCOME TAXATION Under the OID Regulations (as defined in the accompanying Prospectus Supplement), the Notes will be treated as providing for stated interest at a single objective rate. As a result, the Notes will constitute variable rate debt instruments, within the meaning of the OID Regulations. In general, under the OID Regulations, all stated interest on the Notes will constitute qualified stated interest. In particular, the amount of qualified stated interest that accrues with respect to a Note during any accrual period will be determined under the rules applicable to fixed rate debt instruments by assuming that the objective rate (i.e., the Interest Rate Basis) is a fixed rate that reflects the yield that is reasonably expected for the Notes. The qualified stated interest allocable to an accrual period will be increased (or decreased) if the interest actually paid during an accrual period exceeds (or is less than) the interest assumed to be paid during the accrual period pursuant to the foregoing rules. Prospective investors should consult the summary describing the principal United States federal income tax consequences of the ownership and disposition of the Notes contained in the section entitled "United States Federal Income Taxation" in the accompanying Prospectus Supplement.
