Summary

The Accelerated Return Notes^SM Linked to the Dow Jones BRIC 50 Index^SM due December , 2008 (the “Notes”) are senior, unsecured debt securities of Merrill Lynch & Co., Inc. that provide a leveraged return for investors, subject to a cap, if the level of the Dow Jones BRIC 50 Index^SM (Bloomberg Symbol “BRIC50D <Index>“) (the “Index”) increases moderately from the Starting Value of the Index, determined on the Pricing Date, to the Ending Value of the Index, determined on the Calculation Days (as defined in product supplement ARN-1) shortly prior to the maturity date of the Notes. Investors must be willing to forego interest payments on the Notes and willing to accept a return that is capped or a repayment that is less, and potentially significantly less, than the original public offering price of the Notes.

Hypothetical Payout Profile

Hypothetical Payments at Maturity

Examples

Set forth below are three examples of payment at maturity calculations, assuming a hypothetical Starting Value of 595.88, the level of the Index on September 6, 2007 and a Capped Value of $12.00, the midpoint of the range of $11.80 and $12.20.

Example 1—The hypothetical Ending Value is 80% of the hypothetical Starting Value:

Hypothetical Starting Value: 595.88

Hypothetical Ending Value: 476.70

Payment at maturity (per unit) = $8.00

Example 2—The hypothetical Ending Value is 103% of the hypothetical Starting Value:

Hypothetical Starting Value: 595.88

Hypothetical Ending Value: 613.76

Payment at maturity (per unit) = $10.90

Example 3—The hypothetical Ending Value is 120% of the hypothetical Starting Value:

Hypothetical Starting Value: 595.88

Hypothetical Ending Value: 715.06

Payment at maturity (per unit) = $12.00 (Payment at maturity cannot be greater than the Capped Value)

The following table illustrates, for a hypothetical Starting Value of 595.88 and a range of hypothetical Ending Values of the Index:

The table below assumes a Capped Value of $12.00, the midpoint of the range of $11.80 and $12.20.

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 Starting Value, Ending Value, Capped Value and 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.

Investor Considerations

Other Provisions

We may deliver the Notes against payment therefor in New York, New York on a date that is greater than 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.

The Index

All disclosure contained in this term sheet regarding the Index, including, without limitation, its make-up, method of calculation and changes in its components has been derived from publicly available sources. The information reflects the policies of Dow Jones as stated in these sources and these policies are subject to change at the discretion of Dow Jones. ML&Co. and MLPF&S have not independently verified the accuracy or completeness of that information.

Index Basics

The Index was introduced by Dow Jones in June 2006. The stocks underlying the Index (the “Underlying Stocks”) are selected, as described below, from the stocks included in the DJGI country indexes for Brazil, Russia, India and from the H shares, U.S. listed shares and ADRs included in the Dow Jones China Offshore Index. These country indexes cover approximately 95% of the underlying float-adjusted market capitalization of these markets. Stocks are selected from these country indexes for inclusion in the Index on the basis of size and liquidity, and with the objective of optimizing the factors of greatest importance in an investable index: liquidity, turnover rate, transaction costs and tracking error against the broad-market benchmark.

Input Data

Index values are rounded to two decimal places and divisors are rounded to six decimal places. Any values derived by the Index calculation engine from a corporate action used for the divisor adjustments and Index computations are rounded to six decimal places.

Index Construction

Stocks are selected within each country based on size and liquidity rankings, subject to buffers, and then are aggregated to create the Index. The Index selection universe for the Index comprises all H shares, U.S.-listed shares and ADRs in the DJ China Offshore Index, and all components of the Dow Jones Brazil, Russia and India DJGI Indexes.

In the China offshore market and in the Brazil, Russia and India markets, eligible securities are screened for liquidity. Any security that had more than 10 non-trading days over the past quarter is excluded, unless the lack of trading is due to a situation that is deemed to be temporary. The remaining companies are then ranked by float-adjusted market capitalization to represent more accurately the investable size of each security. Stocks in the top 95% of the underlying float-adjusted market capitalization are then selected as components of the underlying indexes that form the universe for the Index, skipping stocks that fall in the bottom 1% of the universe by float-adjusted market capitalization and in the bottom 0.01% of the universe by turnover.

The selection of the initial Underlying Stocks includes the following steps:

Periodic Review

The Index undergoes an annual review process in September, which includes the following steps:

The Underlying Stocks are also reviewed quarterly to coincide with the review of the DJGI. The weighting of each Underlying Stock is capped at 10% of the Index’s total market capitalization at each quarterly update, if necessary.

Changes in the Underlying Stocks as a result of the annual review are announced after the close of trading on the second Friday in September and take effect at the open of trading on the next business day following the third Friday in September. Changes to an Underlying Stock’s shares, free-float factors and 10%-cap factors as a result of the quarterly updates are implemented after the closing values have been established on the third Friday in March, June, September and December, and are effective at the open of the next trading day.

The changes in the Underlying Stocks resulting from the annual review are implemented after the official closing values have been established on the third Friday in September and are effective at the open of the next trading day. Changes to an Underlying Stock’s shares, free-float factors and 10%-cap factors as a result of the quarterly updates are implemented after the closing values have been established on the third Friday in March, June, September and December, and are effective at the open of the next trading day.

Index Maintenance

In addition to the scheduled annual review, the Index is reviewed on an ongoing basis. A change to the Index composition and a related weight adjustment is necessary whenever there is an extraordinary event (e.g. delisting, bankruptcy, merger, takeover, etc.) involving an Underlying Stock. In these cases, each event is accounted for as soon as it is effective. Such changes in the Underlying Stocks are announced, whenever possible, two days prior to their implementation. Divisor adjustments are made using the formulas and procedures set forth by Dow Jones. The current Index divisors are updated daily and are available at the Dow Jones Indexes website.

In the event that an Underlying Stock’s primary-market listing is moved to an ineligible exchange, the company will be removed from the Index.

A selection list is created at the end of each month and upon a listing of any eligible large IPO. The selection list comprises the top 30 companies (10 for Russia) in the DJ China Index and the Brazil, Russia and India country indexes based on float-adjusted market capitalization. The list indicates possible changes in the composition of the Index at the next annual review and is used to determine replacements for stocks that are removed from the Index due to mergers, financial distress or similar extraordinary events.

Any company that is removed from the DJ China Offshore Index or the Brazil, Russia or India DJGI Index that is also an Underlying Stock of the Index is automatically removed from the Index at that time.

If an Underlying Stock is restructured into two or more new companies, the largest new company in terms of market capitalization will be included in the Index immediately after the close of trading on the day of the restructuring becomes effective, provided it otherwise would be eligible for Index membership. If the restructuring involves an Underlying Stock spinning off a portion of its business to form a new company or companies, the parent company, if otherwise eligible for Index membership, generally will be retained in the Index until the next annual review. However, there may be situations where a spinoff, due to its size, may be retained in the Index instead of the legally surviving parent company.

If an Underlying Stock company merges with another company, whether Underlying Stock or non-component, its Index membership will be assumed by the new company immediately after the close of trading on the effective date of the merger, providing the new company also qualifies for the Index. If both companies are current Underlying Stocks, the top-ranked non-component from the most current selection list will fill the vacancy created by the merger.

If an Underlying Stock company is taken over by another Underlying Stock company, the former will be removed from the Index immediately after the close of trading on the day the takeover becomes effective. The replacement will be the highest ranked non-component from the most recent available selection list. If an Underlying Stock company is taken over by a non-component company, the acquiring company will replace its position in the Index, provided the acquiring company meets all eligibility criteria. Otherwise, the highest ranking non-component from the most recent available selection list will be selected as the replacement.

If an Underlying Stock is delisted by its primary market or is in bankruptcy proceedings, it will be removed from the Index immediately. It will be replaced by the highest-ranking non-component from the most recent available selection list.

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 by the discussion under the section entitled “United States Federal Income Taxation” in the accompanying product supplement ARN-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 pre-paid cash-settled forward contract linked to the level of the 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 pre-paid cash-settled forward contracts linked to the level of the Index, upon the receipt of cash on the maturity date of the Notes, a U.S. Holder (as defined in the accompanying product supplement ARN-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 pre-paid cash-settled forward contracts linked to the level of the 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.

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 ARN-1.

Experts

The consolidated financial statements, the related financial statement schedule, and management’s report on the effectiveness of internal control over financial reporting incorporated in this term sheet by reference from ML&Co.’s Annual Report on Form 10-K for the year ended December 29, 2006 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, and the three-month and six-month periods ended June 29, 2007 and June 30, 2006 which are 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 included in ML&Co.’s Quarterly Reports on Form 10-Q for the quarters ended March 30, 2007 and June 29, 2007 (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 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.
