                                     ------

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.

(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 Registrants'  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 Registrants'  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.

In 1999 Merrill Lynch  completed its efforts to address the Year 2000 issue (the
"Y2K issue"). The Y2K issue was the result of a widespread programming technique
that caused 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 a "00," causing computers to incorrectly
interpret  the year as 1900.  Left  uncorrected,  the Y2K issue may have  caused
serious failures in information  technology systems and other systems. The Trust
and the  Partnership  have no  independent  operations  and are  dependent  upon
Merrill Lynch.  Merrill  Lynch's efforts to address the Y2K issue are more fully
discussed in the Merrill  Lynch & Co.,  Inc.  Annual Report on Form 10-K for the
fiscal year ended  December 31,  1999,  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.

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA
         -------------------------------------------

independent   auditors'  reports  set  forth  on  pages  F-1  through  F-15  are

1. ORGANIZATION AND PURPOSE

Merrill Lynch Preferred Capital Trust IV (the "Trust") is a statutory  business
trust  formed  under the laws of the State of Delaware on December  19, 1997 for
the exclusive  purposes of (i) issuing its preferred and common  securities (the
"Trust Preferred  Securities" and the "Trust Common Securities",  respectively),
(ii) purchasing  partnership  preferred  securities (the "Partnership  Preferred
Securities"),  representing  the limited  partnership  interest of Merrill Lynch
Preferred Funding IV, L.P. (the "Partnership"),  with the proceeds from the sale
of Trust Preferred and Common 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 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 (i) pay all fees and  expenses  related to the  organization  and
operations of the Trust (including  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 Trust) and the offering
of the Trust  Preferred  Securities  and (ii) be  responsible  for all debts and
other  obligations of the Trust (other than with respect to the Trust  Preferred
and Common  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. As such, 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 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 COMMON SECURITIES

The Trust issued  494,880 7.12% Trust Common  Securities,  $25  liquidation
amount  per  security,  to the  Company  on June  19,  1998.  The  Trust  Common
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.

INDEPENDENT AUDITORS' REPORT

To the Trustees of
  Merrill Lynch Preferred Capital Trust IV

We have audited the accompanying  balance sheets of Merrill Lynch Preferred
Capital  Trust IV (the  "Trust") as of December  31, 1999 and December 25, 1998,
and the related statements of earnings, changes in stockholders' equity and cash
flows for the period ended December 31, 1999 and for the period June 19, 1998 to
December 25, 1998.  These  financial  statements are the  responsibility  of the
Trust's  management.  Our  responsibility  is to  express  an  opinion  on these
financial statements based on our audit.

We conducted  our audit in  accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion,  such financial  statements present fairly, in all material
respects,  the financial position of the Trust at December 31, 1999 and December
25, 1998,  and the results of its  operations  and its cash flows for the period
ended December 31, 1999 and for the period June 19, 1998 to December 25, 1998 in
conformity with generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS
December 31, 1999
--------------------------------------------------------------------------------


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  purpose of  purchasing
certain  eligible debt  instruments of Merrill Lynch & Co., Inc. (the "Company")
and wholly owned subsidiaries of the Company with (i) the proceeds from the sale
of its  preferred   securities  (the  "Partnership   Preferred   Securities"),
representing a limited  partner  interest,  to Merrill Lynch  Preferred  Capital
Trust IV (the  "Trust")  and (ii) a capital  contribution  from the  Company in
exchange for the general partnership interest in the Partnership.

The Company,  in its capacity as sole general  partner of the  Partnership,  has
agreed  to (i) pay  all  fees  and  expenses  related  to the  organization  and
operations  of  the  Partnership  (including  taxes,  duties,   assessments,  or
government  charges (other than withholding  taxes) imposed by the United States
or any  other  domestic  taxing  authority  upon  the  Partnership)  and (ii) be
responsible for all debts and other  obligations of the Partnership  (other than
with  respect to the  Partnership  Preferred  Securities).  The Company has also
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. As such, 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.

INDEPENDENT AUDITORS' REPORT

To the General Partner and Limited Partner of
  Merrill Lynch Preferred Funding IV, L.P.

We have audited the accompanying  balance sheets of Merrill Lynch Preferred
Funding IV, L.P.  (the  "Partnership")  as of December 31, 1999 and December 25,
1998, and the related statements of earnings,  changes in partners' capital, and
cash flows for the period  ended  December  31, 1999 and for the period June 19,
1998 to December 25, 1998. These financial  statements are the responsibility of
the  Partnership's  management.  Our  responsibility is to express an opinion on
these financial statements based on our audit.

We conducted  our audit in  accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion,  such financial  statements present fairly, in all material
respects,  the financial  position of the  Partnership at December 31, 1999, and
the results of its  operations  and its cash flows for the period ended December
31, 1999 and for the period June 19,  1998 to  December  25, 1998 in  conformity
with generally accepted accounting principles.
