Summary

The Merrill Lynch Long Short Notes^SM Linked to the Consumer Staples Select Sector/Consumer Discretionary Select Sector Long Short Index—Series XVIII due May     , 2009 (the “Notes”) are senior, unsecured debt securities of Merrill Lynch & Co., Inc. (“ML&Co.”) designed for investors seeking exposure to a leveraged long position in the Consumer Staples Select Sector Index and a short position in the Consumer Discretionary Select Sector Index.

The Consumer Staples Select Sector/Consumer Discretionary Select Sector Long Short Index—Series XVIII (the “Composite Index”) will reflect a leveraged long position in the the Consumer Staples Select Sector Index (the “Long Component”) equal to 150% of the initial level of the Composite Index, and a short position in the Consumer Discretionary Select Sector Index (the “Short Component”, and each Long Component or Short Component, an “Index Component”) equal to 50% of the initial level of the Composite Index. The Composite Index will not take into account the dividends paid on any of the stocks included in the Long Component or the Short Component.

Investors will receive a return on their investment if the level of the Composite Index increases from the Starting Value of the Composite Index, determined on the Pricing Date, to the Ending Value of the Composite Index, determined on the Calculation Days shortly prior to the maturity date of the Notes, unless redeemed by us as indicated below. Investors must be willing to forego interest payments on the Notes and be willing to accept a repayment that may be less, and potentially significantly less, than the original public offering price of the Notes.

Terms of the Notes		Determining Payment for the Notes

Hypothetical Payments at Maturity

Examples

Set forth below are six examples of Redemption Amount calculations, assuming:

For each Index Component, the following table sets forth the hypothetical Starting Value, the hypothetical Multiplier and the hypothetical closing level used to calculate the level of the Composite Index and the Redemption Amount in each of the examples below.

Example 1 – The level of each Index Component has increased by 5%:

Example 2 – The level of the Long Component has increased by 5% and the level of the Short Component has increased by 17%:

Example 3 – The level of the Long Component has increased by 5% and the level of the Short Component has decreased by 5%:

Example 4 – The level of the Long Component has decreased by 17% and the level of the Short Component has increased by 5%:

Example 5 – The level of each Index Component has decreased by 5%:

Example 6 – The level of the Long Component has decreased by 5% and the level of the Short Component has decreased by 17%:

The following table illustrates, for the Starting Value of 100 and a range of hypothetical Ending Values:

This table assumes that the closing level of the Composite Index is not equal to or less than 50 on any date before the first scheduled Calculation Day of the Calculation Period. Therefore, the Notes were not subject to early redemption.

                The above figures are for purposes of illustration only. The actual amount received by you and the resulting total and pretax annualized rates of return will depend on the actual Multipliers, the actual Ending Value and the actual term of your investment.

Risk Factors

An investment in the Notes involves significant risks. The following is a list of certain of the risks involved in investing in the Notes. You should carefully review the more detailed explanation of risks relating to the Notes in the “Risk Factors” sections included in the product supplement and MTN prospectus supplement identified below under “Additional Note Terms”. We also urge you to consult your investment, legal, tax, accounting and other advisers before you invest in the Notes.

Additional Risk Factor

MLPF&S, acting as the Index Compilation Agent, will determine the composition the Select Sector Indices after consultation with Standard & Poor’s. The stocks included in each Select Sector Index, including the Consumer Staples Select Sector Index and the Consumer Discretionary Select Sector Index, are selected by MLPF&S (the “Index Compilation Agent”). The Index Compilation Agent, after consultation with Standard & Poor’s (“S&P”), assigns a company’s stock to a particular Select Sector Index on the basis of the company’s sales and earnings composition and the sensitivity of the company’s stock price and business results to the common factors that affect other companies in each Select Sector Index. S&P has sole control over the removal of stocks from the S&P 500 Index and the selection of replacement stocks to be added to the S&P 500 Index. However, S&P plays only a consulting roles in the Select Sector Index assignment of the S&P 500 Index component stocks, which is the sole responsibility of the Index Compilation Agent. The Index Compilation Agent will compile the Select Sector Indices without regard to the Notes. The Index Compilation Agent has no obligation to take the interests of the Note holders into consideration in compiling the Select Sector Indices, including when compiling the Consumer Staples Select Sector Index and the Consumer Discretionary Select Sector Index.

Investor Considerations

Other Provisions

We may deliver the Notes against payment therefor in New York, New York on a date that is in excess of three business days following the Pricing Date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, if the initial settlement on the Notes occurs more than three business days from the Pricing Date, purchasers who wish to trade Notes more than three business days prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

If you place an order to purchase these offered securities, you are consenting to each of MLPF&S and its broker-dealer affiliate First Republic Securities Company, LLC acting as a principal in effecting the transaction for your account. MLPF&S is acting as an underwriter and/or selling agent for this offering and will receive underwriting compensation from the issuer of the securities.

Supplement to the Plan of Distribution

MLPF&S and First Republic Securities Company, LLC, each a broker-dealer subsidiary of ML&Co., are members of the Financial Industry Regulatory Authority, Inc. (formerly the National Association of Securities Dealers, Inc. (the “NASD”)) and will participate in distribution of the Notes. Accordingly, offerings of the Notes will conform to the requirements of NASD Rule 2720.

MLPF&S and First Republic Securities Company, LLC may use this Note Prospectus for offers and sales in secondary market transactions and market-making transactions in the Notes. MLPF&S and First Republic Securities Company, LLC may act as principal or agent in these transactions, and any such sales will be made at prices related to prevailing market prices at the time of the sale.

The Composite Index

The Composite Index is designed to allow investors to participate in the percentage change in the value of a leveraged long position in the Consumer Staples Select Sector Index and a short position in the Consumer Discretionary Select Sector Index, both indices comprising the Composite Index, from the Starting Value to the Ending Value of the Notes. The Index Components are described in the section below. Each Index Component will be assigned a weighting and that weighting will reflect the relative contribution of that Index Component to the level of the Composite Index. The positive weighting of 150% of the initial level of the Composite Index in the Long Component can be viewed as a leveraged long position in the Long Component. The negative weighting of 50% of the initial level of the Composite Index in the Short Component can be viewed as a short position in the Short Component.

The publisher of the Index Components has no obligations relating to the Notes or amounts to be paid to you, including any obligation to take the needs of Merrill Lynch & Co., Inc. or of holders of the Notes into consideration for any reason. The publisher will not receive any of the proceeds of the offering of the Notes and is not responsible for, and has not participated in, the offering of the Notes and is not responsible for, and will not participate in, the determination or calculation of the amount receivable by holders of the Notes. All disclosure contained in this term sheet regarding an Index Component, including with limitation, its make-up, method of calculation and changes in components has been derived from publicly available information prepared by the distributor of the Index Component. Neither Merrill Lynch & Co., Inc. nor MLPF&S have independently verified the accuracy or completeness of that information.

For more information on the Composite Index, please see the section entitled “The Composite Index” in the product supplement LS-1.

If January 23, 2008 were the Pricing Date, for each Index Component, the weighting, closing level, Multiplier and initial Composite Index contribution would be as follows:

While historical information on the Composite Index will not exist before the Pricing Date, the following graph sets forth the hypothetical historical performance of the Composite Index in the period from January 2002 through December 2007, based upon historical levels of each Index Component, the hypothetical Multipliers and a Composite Index level of 100 on January 23, 2008. This hypothetical historical data on the Composite Index is not necessarily indicative of the future performance of the Composite Index or what the value of the Notes may be. Any historical upward or downward trend in the level of the Composite Index during any period set forth below is not an indication that the Composite Index is more or less likely to increase or decrease at any time over the term of the Notes.

The Index Components

The Select Sector Indices

The Select Sector Indices are sub-indices of the S&P 500 Index. Each stock in the S&P 500 Index is allocated to only one Select Sector Index, and the combined companies of the nine Select Sector Indexes represent all of the companies in the S&P 500 Index. The industry indexes are sub-categories within each Select Sector Index and represent a specific industry segment of the overall Select Sector Index. The nine Select Sector Indices, with the approximate percentage of the market capitalization of the S&P 500 Index included in each sector as of December 31, 2007 indicated in parentheses, are: Consumer Discretionary (8.5%); Consumer Staples (10.2%); Energy (12.9%); Financials (17.6%); Health Care (12.0%); Industrials (11.5%); Technology (20.3%); Materials (3.3%); and Utilities (3.6%).

Each Select Sector Index was developed and is maintained in accordance with the following criteria:

Each Select Sector Index is calculated using the same methodology utilized by S&P in calculating the S&P 500 Index, using a base-weighted aggregate methodology. The daily calculation of each Select Sector Index is computed by dividing the total market value of the companies in the Select Sector Index by a number called the index divisor.

The Index Compilation Agent at any time may determine that a Component Stock which has been assigned to one Select Sector Index has undergone such a transformation in the composition of its business that it should be removed from that Select Sector Index and assigned to a different Select Sector Index. In the event that the Index Compilation Agent notifies ISG that a Component Stock’s Select Sector Index assignment should be changed, the AMEX will disseminate notice of the change following its standard procedure for announcing index changes and will implement the change in the affected Select Sector Indexes on a date no less than one week after the initial dissemination of information on the sector change to the maximum extent practicable. It is not anticipated that Component Stocks will change sectors frequently.

Component Stocks removed from and added to the S&P 500 Index will be deleted from and added to the appropriate Select Sector Index on the same schedule used by S&P for additions and deletions from the S&P 500 Index insofar as practicable.

The Long Component — The Consumer Staples Select Sector Index

The Consumer Staples Index (IXR) is a modified market capitalization-based index intended to track the movements of companies that are components of the S&P 500 Index and are involved in the development or production of consumer products.

Any historical upward or downward trend in the level of the Consumer Staples Select Sector Index during any period set forth below is not an indication that the Index is more or less likely to increase or decrease at any time over the term of the Notes. On January 23, 2008, the closing level of the Consumer Staples Select Sector Index was 271.66.

The Short Component — The Consumer Discretionary Select Sector Index

The Consumer Discretionary Select Sector Index (IXY) is a modified market capitalization-based index intended to track the movements of companies that are components of the S&P 500 Index and are involved in the development or production of cyclical products or the transportation industry. Cyclical and transportation products include building materials, retailers, appliances, housewares, air transportation, automotive manufacturing, shipping, and trucking; The Consumer Discretionary Select Sector Index, which serves as the benchmark for the Consumer Discretionary Select Sector SPDR Fund (XLY), was established with a value of 250.00 on June 30, 1998.

The following graph sets forth the historical performance of the Consumer Discretionary Select Sector Index in the period from January 2002 through December 2007. This historical data on the Consumer Discretionary Select Sector Index is not necessarily indicative of the future performance of the Consumer Discretionary Select Sector Index or what the value of the Notes may be.

Certain U.S. Federal Income Taxation Considerations

Set forth below is a summary of certain U.S. federal income tax considerations relating to an investment in the Notes. The following summary is not complete and is qualified in its entirety to the discussion under the section entitled “United States Federal Income Taxation” in the accompanying product supplement LS-1 and MTN prospectus supplement, which you should carefully review prior to investing in the Notes.

General. There are no statutory provisions, regulations, published rulings or judicial decisions addressing or involving the characterization and treatment, for United States federal income tax purposes, of the Notes or securities with terms substantially the same as the Notes. Accordingly, the proper United States federal income tax characterization and treatment of the Notes is uncertain. Pursuant to the terms of the Notes, ML&Co. and every holder of a Note agree (in the absence of an administrative determination, judicial ruling or other authoritative guidance to the contrary) to characterize and treat a Note for all tax purposes as a cash-settled financial contract linked to the level of the Composite Index. Due to the absence of authorities that directly address instruments that are similar to the Notes, significant aspects of the United States federal income tax consequences of an investment in the Notes are not certain, and no assurance can be given that the Internal Revenue Service (the “IRS”) or the courts will agree with the characterization and tax treatment described above. Accordingly, prospective purchasers are urged to consult their own tax advisors regarding the United States federal income tax consequences of an investment in the Notes (including alternative characterizations and tax treatments of the Notes) and with respect to any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

Payment on the Maturity Date. Assuming that the Notes are properly characterized and treated as cash-settled financial contracts linked to the level of the Composite Index, upon the receipt of cash on the maturity date of the Notes, a U.S. Holder (as defined in the accompanying product supplement

LS-1) will recognize gain or loss. The amount of such gain or loss will be the extent to which the amount of the cash received differs from the U.S. Holder’s tax basis in the Note. A U.S. Holder’s tax basis in a Note generally will equal the amount paid by the U.S. Holder to purchase the Note. It is uncertain whether any such gain or loss would be treated as ordinary income or loss or capital gain or loss. Absent a future clarification in current law (by an administrative determination, judicial ruling or otherwise), where required, ML&Co. intends to report any such gain or loss to the IRS in a manner consistent with the treatment of such gain or loss as capital gain or loss. If such gain or loss is treated as capital gain or loss, then any such gain or loss will be long-term capital gain or loss if the U.S. Holder has held the Note for more than one year as of the maturity date.

Sale or Exchange of the Notes. Assuming that the Notes are properly characterized and treated as cash-settled financial contracts linked to the level of the Composite Index, upon a sale or exchange of a Note prior to the maturity date of the Notes, a U.S. Holder will generally recognize capital gain or loss in an amount equal to the difference between the amount realized on such sale or exchange and such U.S. Holder’s tax basis in the Note so sold or exchanged. Any such capital gain or loss will be long-term capital gain or loss if the U.S. Holder has held the Note for more than one year as of the date of such sale or exchange.

Early Redemption of the Notes. Assuming that the Notes are properly characterized and treated as cash-settled financial contracts linked to the level of the Composite Index, upon an early redemption of the Notes, a U.S. Holder will recognize gain or loss. The amount of that gain or loss will be the extent to which the amount of the cash received differs from the U.S. Holder’s tax basis in the Note. Any such gain or loss will be treated as capital gain or loss. Any such capital gain or loss will be short-term or long-term capital gain or loss, depending upon the U.S. Holder’s holding period for the Notes as of the date of such early redemption. The deductibility of capital losses is subject to certain limitations.

Possible Future Tax Law Changes. On December 7, 2007, the IRS released a notice that could possibly affect the taxation of holders of the Notes. According to the notice, the IRS and the U.S. Department of the Treasury (the “Treasury Department”) are actively considering, among other things, whether the holder of an instrument having terms similar (but not identical) to the Notes should be required to accrue either ordinary income or capital gain on a current basis, and they are seeking comments on the subject. It is not possible to determine what guidance they will ultimately issue, if any. It is possible, however, that under such guidance, holders of instruments having terms similar to the Notes will ultimately be required to accrue income currently and this could be applied on a retroactive basis. The IRS and the Treasury Department are also considering other relevant issues, including whether additional gain or loss from such instruments should be treated as ordinary or capital, whether foreign holders of such instruments should be subject to withholding tax on any deemed income accruals, whether the tax treatment of such instruments should vary depending upon whether or not such instruments are traded on a securities exchange, whether such instruments should be treated as indebtedness, whether the tax treatment of such instruments should vary depending upon the nature of the underlying asset, and whether the special “constructive ownership rules” contained in Section 1260 of the Internal Revenue Code of 1986, as amended might be applied to such instruments. Holders are urged to consult their tax advisors concerning the significance, and the potential impact, if any, of the above considerations to their investment in the Notes. ML&Co. intends to continue to treat the Notes for U.S. federal income tax purposes in accordance with the treatment described herein unless and until such time as the Treasury Department and IRS determine that some other treatment is more appropriate.

Circular 230 Legend. The foregoing discussion of United States federal income tax matters contained in this term sheet (a) was not intended or written to be legal or tax advice to any person and was not intended or written to be used, and it cannot be used, by any person for the purpose of avoiding any tax-related penalties that may be imposed on such person, and (b) was written to support the promotion or marketing of the Notes by Merrill Lynch. Each person considering an investment in the Notes should seek advice based on its particular circumstances from an independent tax advisor.

Notwithstanding anything to the contrary contained herein, each prospective investor (and each employee, representative, or other agent of each prospective investor) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the Notes and all materials of any kind that are provided to the prospective investor relating to such tax treatment and tax structure (as such terms are defined in Treasury Regulation Section 1.6011-4). This authorization of tax disclosure is retroactively effective to the commencement of discussions between Merrill Lynch or its representatives and each prospective investor regarding an investment in the Notes.

Prospective purchasers of the Notes should consult their own tax advisors concerning the tax consequences, in light of their particular circumstances, under the laws of the United States and any other taxing jurisdiction, of the purchase, ownership and disposition of the Notes. See the discussion under the section entitled “United States Federal Income Taxation” in the accompanying product supplement LS-1.

Experts

The consolidated financial statements and management’s report on the effectiveness of internal control over financial reporting, included as Exhibit 99.1 in the Current Report on Form 8-K dated November 13, 2007 (“November 13, 2007 Form 8-K”) and the related financial statement schedule included in ML&Co.’s Form 10-K for the year ended December 29, 2006 are incorporated in this term sheet by reference, and have been audited by Deloitte &

Touche LLP, an independent registered public accounting firm, as stated in their reports, which are incorporated herein by reference (which reports (1) express an unqualified opinion on the consolidated financial statements and the related financial statement schedule and include an explanatory paragraph regarding the change in accounting method in 2006 for share-based payments to conform to Statement of Financial Accounting Standard No. 123 (revised 2004), Share-Based Payment, (2) express an unqualified opinion on management’s assessment regarding the effectiveness of internal control over financial reporting, and (3) express an unqualified opinion on the effectiveness of internal control over financial reporting), and have been so incorporated in reliance upon the reports of such firm given upon their authority as experts in accounting and auditing.

With respect to the unaudited condensed consolidated interim financial information for the three-month periods ended March 30, 2007 and March 31, 2006, the three-month and six-month periods ended June 29, 2007 and June 30, 2006, and the three-month and nine-month periods ended September 28, 2007 and September 29, 2006 which is incorporated herein by reference, Deloitte & Touche LLP, an independent registered public accounting firm, have applied limited procedures in accordance with the standards of the Public Company Accounting Oversight Board (United States) for a review of such information. However, as stated in their reports for the quarters ended March 30, 2007, included as Exhibit 99.3 in the November 13, 2007 Form 8-K, June 29, 2007, included as Exhibit 99.2 in the November 13, 2007 Form 8-K, and September 28, 2007 included in ML&Co.’s Quarterly Reports on Form 10-Q (which reports include an explanatory paragraph regarding the adoption of Statement of Financial Accounting Standards No. 157, “Fair Value Measurement”, Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115,” and FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109”) and incorporated by reference herein, they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their reports on such information should be restricted in light of the limited nature of the review procedures applied. Deloitte & Touche LLP are not subject to the liability provisions of Section 11 of the Securities Act of 1933 (the “Act”) for their reports on the unaudited condensed consolidated interim financial information because those reports are not “reports” or a “part” of the registration statement prepared or certified by an accountant within the meaning of Sections 7 and 11 of the Act.
