                                     PART I
                                     ------

ITEM 1.  BUSINESS
         --------

         MERRILL LYNCH PREFERRED CAPITAL TRUST I

         Merrill  Lynch  Preferred  Capital Trust I (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 November 20, 1996, which was  subsequently  amended by
an amended and restated  declaration of trust dated as of December 11, 1996. The
Trust  exists  for the  exclusive  purposes  of (i)  issuing  trust  securities,
consisting of 7-3/4% 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  7-3/4%  Partnership   Preferred
Securities  (the  "Partnership  Preferred  Securities")  issued by Merrill Lynch
Preferred Funding I, L.P. (the "Partnership"),  and (iii) engaging in only those
other activities necessary or incidental thereto.

         MERRILL LYNCH PREFERRED FUNDING I, 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 November 20, 1996, which was  subsequently  amended by
an amended and restated  agreement  of limited  partnership  dated  December 17,
1996.  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 I", "Merrill Lynch Preferred Funding I, 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 December 11, 1996, of

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 December 17, 1996 and
payable  quarterly  in  arrears  on each  March 30,  June 30,  September  30 and
December 30,  commencing  December 30, 1996,  at an annual rate of 7-3/4% 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 7-3/4%.
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 November 20, 1996,  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 November  20,  1996,  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 December 17, 1996,  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
         -------------------------------------------

NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION AND PURPOSE

Merrill Lynch  Preferred  Capital Trust I (the "Trust") is a statutory  business
trust  formed  under the laws of the State of Delaware on November  20, 1996 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 I, 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.

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  11,340,208  7  3/4%  Partnership  Preferred  Securities,  $25
liquidation  preference per security.  The interest payment dates and redemption
provisions of the Partnership Preferred  Securities,  which are redeemable after
December  30,  2006  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 11,000,000 7 3/4% Trust Preferred  Securities,  $25 liquidation
amount per  security  in a public  offering  on  December  17,  1996.  The Trust
Preferred  Securities are redeemable on or after December 30, 2006 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 340,208 7 3/4% Trust Common Securities,  $25 liquidation amount
per security,  to the Company on December 17, 1996. The Trust Common  Securities
are  redeemable  on or after  December  30, 2006 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 I

We have audited the accompanying  balance sheets of Merrill Lynch Preferred
Capital Trust I (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 three years ended December 31, 1999.  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 audits.

We conducted  our audits 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 audits provide 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 three
years ended December 31, 1999 in conformity with generally  accepted  accounting
principles.

MERRILL LYNCH PREFERRED FUNDING I, L.P.
NOTES TO FINANCIAL STATEMENTS
December 31, 1999
--------------------------------------------------------------------------------


1. ORGANIZATION AND PURPOSE

Merrill Lynch Preferred  Funding I, L.P. (the  "Partnership")  is a limited
partnership   that  was  formed  under  the  Delaware  Revised  Uniform  Limited
Partnership  Act on November 20, 1996 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 I (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

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 3/4%  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 December 30, 2006, 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 11,340,208 7 3/4% Partnership Preferred  Securities,  $25
liquidation  preference  per  security,  to the  Trust  on  December  17,  1996.
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 December 30, 2006 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 I, L.P.

We have audited the accompanying  balance sheets of Merrill Lynch Preferred
Funding I, 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  three  years  ended  December  31,  1999.  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 audits.

We conducted  our audits 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 audits provide 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
December 25, 1998,  and the results of its operations and its cash flows for the
three years  ended  December  31, 1999 in  conformity  with  generally  accepted
accounting principles.
