                                     PART I

ITEM 1. Business

      Merrill Lynch Preferred Capital Trust IV

      Merrill Lynch Preferred Capital Trust IV (the "Trust") is a statutory
business trust formed under the Delaware Business Trust Act, as amended,
pursuant to a declaration of trust and the filing of a certificate of trust with
the Secretary of State on December 19, 1997, which was subsequently amended by
an amended and restated declaration of trust dated as of June 16, 1998. The
Trust exists for the exclusive purposes of (i) issuing trust securities,
consisting of 7.12% Trust Originated Preferred Securities (the "TOPrS") and
trust common securities (the "Trust Common Securities"), representing undivided
beneficial ownership interests in the assets of the Trust, (ii) investing the
gross proceeds of the trust securities in 7.12% Partnership Preferred Securities
(the "Partnership Preferred Securities") issued by Merrill Lynch Preferred
Funding IV, L.P. (the "Partnership"), and (iii) engaging in only those other
activities necessary or incidental thereto.

      Merrill Lynch Preferred Funding IV, L.P.

      The Partnership is a limited partnership formed under the Delaware Revised
Uniform Limited Partnership Act, as amended, pursuant to an agreement of limited
partnership and the filing of a certificate of limited partnership with the
Secretary of State on December 19, 1997, which was subsequently amended by an
amended and restated agreement of limited partnership dated June 19, 1998.
Merrill Lynch & Co., Inc. (the "Company") is the sole general partner of the
Partnership. The Partnership is managed by the general partner and exists for
the exclusive purposes of (i) issuing its partnership interests, consisting of
the Company's general partner interest and the Partnership Preferred Securities,
(ii) investing the proceeds thereof in certain eligible securities of the
Company and wholly owned subsidiaries of the Company (the "Affiliate Investment
Instruments") and certain eligible debt securities, and (iii) engaging in only
those other activities necessary or incidental thereto.

      The information set forth under the headings "Merrill Lynch Preferred
Capital Trust IV", "Merrill Lynch Preferred Funding IV, L.P.", "Description of
the Trust Preferred Securities", "Description of the Trust Guarantee",
"Description of the Partnership Preferred Securities", "Description of the
Partnership Guarantee", and "Use of Proceeds" in the Prospectus dated June 16,
1998 of the Trust and the Partnership is incorporated by reference herein.

ITEM 2. Properties

      Not Applicable.

ITEM 3. Legal Proceedings

      The Registrants know of no material legal proceedings involving the Trust,
the Partnership or the assets of either of them.

ITEM 4. Submission of Matters to a Vote of Security Holders

      No matter was submitted to a vote of holders of any securities of the
Trust or the Partnership during the fiscal year covered by this report.

                                     PART II

ITEM 5. Market for Registrants' Common Equity and Related Stockholder Matters

      (a) There is no established public market for the Trust Common Securities
or the general partnership interest in the Partnership.


                                       1
<PAGE>

      (b) All of the Trust Common Securities and the entire general partnership
interest in the Partnership are owned of record and beneficially by the Company.

      (c) The Company, as holder of the Trust Common Securities, is entitled to
receive cumulative cash distributions accumulating from June 19, 1998 and
payable quarterly in arrears on each March 30, June 30, September 30 and
December 30, commencing September 30, 1998, at an annual rate of 7.12% of the
liquidation amount per annum. Distributions not paid on the scheduled payment
date will accumulate and compound quarterly at a rate per annum equal to 7.12%.
The certificate of limited partnership of the Partnership does not require any
regular periodic distributions to be made to the general partner; however, to
the extent that aggregate payments to the Partnership on the Affiliate
Investment Instruments and on certain eligible debt securities exceed
distributions accumulated or payable with respect to the Partnership Preferred
Securities, the Partnership may at times have excess funds which shall be
allocated to and may, in the general partner's sole discretion, be distributed
to the general partner.

ITEM 6. Selected Financial Data

      The Registrant's activities are limited to issuing securities and
investing the proceeds as described in ITEM 1. -- Business, above. Accordingly,
the financial statements included herein in response to ITEM 8. -- Financial
Statements and Supplementary Data are incorporated by reference in response to
this item.

ITEM 7. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

      The Registrant's activities are limited to issuing securities and
investing the proceeds as described in ITEM 1. -- Business above. Since the
Trust was organized on December 19, 1997, its activities, as specified in its
declaration of trust, have been limited to the issuance of the TOPrS and the
Trust Common Securities, the investing of the proceeds in the Partnership
Preferred Securities, and the payment of distributions on the TOPrS and the
Trust Common Securities in accordance with their terms. Since the Partnership
was organized on December 19, 1997, its activities, as specified in its
agreement of limited partnership, have been limited to the issuance of the
Partnership Preferred Securities, the receipt of a capital contribution from the
Company, as general partner, the investment of the proceeds in Affiliate
Investment Instruments and certain eligible debt securities, and the payment of
distributions on the Partnership Preferred Securities.

      As the millennium approaches, Merrill Lynch has undertaken initiatives to
address the Year 2000 problem (the "Y2K problem"). The Y2K problem is the result
of a widespread programming technique that causes computer systems to identify a
date based on the last two numbers of a year, with the assumption that the first
two numbers of the year are "19". As a result, the year 2000 would be stored as
"00," causing computers to incorrectly interpret the year as 1900. Left
uncorrected, the Y2K problem may cause information technology systems (e.g.,
computer databases) and non-information technology systems (e.g., elevators) to
produce incorrect data or cease operating completely. The Trust and the
Partnership have no independent operations and are dependent upon Merrill Lynch.
The Y2K problem, and the steps Merrill Lynch has taken to address this problem,
are more fully discussed in the Merrill Lynch & Co., Inc. Annual Report on Form
10-K for the fiscal year ended December 25, 1998 filed with the Securities and
Exchange Commission.

ITEM 7A. Quantitative and Qualitative Disclosure about Market Risk

      On June 19, 1998, the Trust invested the gross proceeds from the sale of
the Trust Common Securities and the TOPrS in the Partnership Preferred
Securities (the "Trust Assets"). The Partnership, in turn, invested the proceeds
from the sale of the Partnership Preferred Securities and a capital contribution
from ML & Co. in certain Affiliate Investment Instruments and eligible
securities (the "Partnership Assets"). To the extent the Partnership has funds
available from the Partnership Assets, the general partner of the Partnership
may declare distributions to the Trust, as holder of the Partnership Preferred
Securities. The Trust's ability to pay distributions to the holders of the TOPrS
is dependent on its receipt of distributions on the Trust Assets from the
Partnership. Therefore, upon the receipt by the Partnership of payments from the
Partnership Assets and the distribution thereof to the Trust, the Trust will
pass through such payments to the holders of the TOPrS.

1.    ORGANIZATION AND PURPOSE

      Merrill Lynch Preferred Capital Trust IV (the "Trust") is a statutory
      business trust formed on December 19, 1997 under the laws of the State of
      Delaware for the exclusive purposes of (i) issuing the Trust Originated
      Preferred Securities (the "Trust Preferred Securities") and the Trust
      Common Securities (together with the Trust Preferred Securities, the
      "Trust Securities") representing undivided beneficial ownership interests
      in the assets of the Trust, (ii) purchasing Partnership Preferred
      Securities (the "Partnership Preferred Securities") representing the
      limited partnership interests of Merrill Lynch Preferred Funding IV, L.P.
      (the "Partnership") with the proceeds from the sale of the Trust
      Securities, and (iii) engaging in only those other activities necessary or
      incidental thereto. The Trust has a perpetual existence, subject to
      certain termination events as provided in the Declaration of Trust under
      which it was formed.

      Merrill Lynch & Co., Inc. (the "Company") has paid compensation to the
      underwriters of the offering of the Trust Preferred Securities. The
      Company also has agreed to pay all fees and expenses related to the
      organization and operations of the Trust (including any taxes, duties,
      assessments or governmental charges of whatever nature (other than
      withholding taxes) imposed by the United States or any other domestic
      taxing authority upon the Trust) and be responsible for all debts and
      other obligations of the Trust (other than with respect to the Trust
      Securities). The Company has agreed to indemnify the trustees and certain
      other persons.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      BASIS OF PRESENTATION

      The financial statements are presented in accordance with U.S. generally
      accepted accounting principles, which require management to make estimates
      that affect reported amounts and disclosure of contingencies in the
      financial statements. Actual results could differ from those estimates.

      INVESTMENT

      The investment in Partnership Preferred Securities represents a limited
      partnership interest in the Partnership and is recorded at cost. As of
      year end, the fair value of the investment approximates its carrying
      value. Income on the Partnership Preferred Securities is accrued when
      earned.

      INCOME TAXES

      The Trust does not incur any income tax liabilities. Such liabilities are
      incurred directly by the security holders.

3.    INVESTMENT IN PARTNERSHIP PREFERRED SECURITIES

      The Trust holds 16,494,880 7.12% Partnership Preferred Securities, $25
      liquidation preference per security. The interest payment dates and
      redemption provisions of the Partnership Preferred Securities, which are
      redeemable on or after June 30, 2008 at the option of the Partnership,
      correspond to the distribution payment dates and redemption provisions of
      the Trust Preferred Securities. Upon any redemption of the Partnership
      Preferred Securities, the Trust Preferred Securities will be redeemed. The
      Company has guaranteed, on a subordinated basis, the payment of
      distributions by the Partnership on the Partnership Preferred Securities
      if, as, and when declared out of funds legally available and payments upon
      liquidation of the Partnership or the redemption of the Partnership
      Preferred Securities to the extent of funds legally available.

4.    STOCKHOLDERS' EQUITY

      TRUST PREFERRED SECURITIES

      The Trust issued 16,000,000 7.12% Trust Preferred Securities, $25
      liquidation amount per security, in a public offering on June 19, 1998.
      The Trust Preferred Securities are redeemable on or after June 30, 2008 at
      the option of the Trust, in whole or in part, at a redemption price equal
      to $25 per security. Distributions on the Trust Preferred Securities are
      cumulative from the date of original issue and are payable quarterly if,
      as, and when the Trust has funds available for payment. Holders of the
      Trust Preferred Securities have limited voting rights and are not entitled
      to vote to appoint, remove or replace, or to increase or decrease the
      number of, trustees, which voting rights are vested exclusively in the
      holder of the Trust Common Securities. Under certain circumstances, the
      Trust Preferred Securities have preferential rights to payment relative to
      the Trust Common Securities.

      The Company has guaranteed, on a subordinated basis, the payment in full
      of all distributions and other payments on the Trust Preferred Securities
      to the extent that the Trust has funds legally available. This guarantee
      and the partnership distribution guarantee are subordinated to all other
      liabilities of the Company and rank equally with the most senior preferred
      stock of the Company.

      Trust, in whole or in part, at a redemption price equal to $25 per
      security.

MERRILL LYNCH PREFERRED FUNDING IV, L.P.
NOTES TO FINANCIAL STATEMENTS
DECEMBER 25, 1998
--------------------------------------------------------------------------------

1.    ORGANIZATION AND PURPOSE

      Merrill Lynch Preferred Funding IV, L.P. (the "Partnership") is a limited
      partnership that was formed under the Delaware Revised Uniform Limited
      Partnership Act on December 19, 1997 for the exclusive purposes of
      purchasing certain eligible debt instruments of Merrill Lynch & Co., Inc.
      (the "Company") and wholly owned subsidiaries of the Company with the
      proceeds from the sale of Partnership Preferred Securities (the
      "Partnership Preferred Securities") to Merrill Lynch Preferred Capital
      Trust IV (the "Trust") and a capital contribution from the Company in
      exchange for the general partnership interest in the Partnership
      (collectively, the "Partnership Proceeds").

      The Company serves as the sole general partner of the Partnership. The
      Company, in its capacity as General Partner of the Partnership, has agreed
      to pay all fees and expenses related to the organization and operations of
      the Partnership (including any taxes, duties, assessments or government
      charges of whatever nature (other than withholding taxes) imposed by the
      United States or any other domestic taxing authority upon the Partnership)
      and be responsible for all debts and other obligations of the Partnership
      (other than with respect to the Partnership Preferred Securities). The
      Company has agreed to indemnify certain officers and agents of the
      Partnership.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      BASIS OF PRESENTATION

      The financial statements are presented in accordance with U.S. generally
      accepted accounting principles, which require management to make estimates
      that affect reported amounts and disclosure of contingencies in the
      financial statements. Actual results could differ from those estimates.

      INVESTMENTS

      The Partnership's investment in affiliate debentures is recorded at cost,
      and its investment in U.S. Treasury bills is classified as
      available-for-sale and recorded at accreted cost, which approximates fair
      value.

      INCOME TAXES

      The Partnership does not incur any income tax liabilities. Such
      liabilities are incurred directly by the partners.

3.    INVESTMENT IN AFFILIATE DEBENTURES

      The Partnership holds debentures of the Company and a wholly owned
      subsidiary of the Company. The debentures have a term of approximately 20
      years and bear interest at 7.12% per annum. The interest payment dates and
      redemption provisions of the debentures, which are redeemable at the
      option of the Company and its subsidiary on or after June 30, 2008,
      correspond to the distribution payment dates and redemption provisions of
      the Partnership Preferred Securities. Interest and redemption payments on
      the subsidiary debenture are guaranteed by the Company on a subordinated
      basis.

4.    PARTNERS' CAPITAL

      The Partnership issued 16,494,880 7.12% Partnership Preferred Securities,
      $25 liquidation preference per security, to the Trust on June 19, 1998.
      Distributions on the Partnership Preferred Securities are cumulative from
      the date of original issue and are payable quarterly if, as, and when
      declared by the general partner. The Partnership Preferred Securities are
      redeemable on or after June 30, 2008 at the option of the Partnership, at
      a redemption price equal to $25 per security. Except as provided in the
      Limited Partnership Agreement and Partnership Preferred Securities
      Guarantee Agreement, and as otherwise provided by law, the holders of the
      Partnership Preferred Securities have no voting rights.

      The Company has guaranteed the payment of distributions by the Partnership
      on the Partnership Preferred Securities if, as, and when declared out of
      funds legally available and payments upon liquidation of the Partnership
      or the redemption of the Partnership Preferred Securities to the extent of
      funds legally available. This guarantee is subordinated to all other
      liabilities of the Company and ranks equally with the most senior
      preferred stock of the Company.
