                        CENTURY PENSION INCOME FUND XXIII

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)


Note A - Basis of Presentation

As of December 31, 1999, Century Pension Income Fund XXIII (the "Partnership" or
"Registrant") adopted the liquidation basis of accounting.

The Partnership's  Nonrecourse  Promissory Notes (the "Notes") were secured by a
deed of trust on all properties owned in fee by the Partnership.  The Notes were
issued in two series.  The "1985 Series Notes", in the original principal amount
of $33,454,000 bear interest at 12% per annum,  and the "1986 Series Notes",  in
the original  principal  amount of  $8,485,000,  bear interest at 10% per annum,
except that portions of the interest  were  deferred,  provided the  Partnership
made minimum interest payments of 5% on the unpaid principal balance.  The Notes
had a balance of principal and deferred interest of approximately $80,000,000 at
their maturity date of February 15, 1999. The  Partnership was unable to satisfy
the Notes at maturity  and as a result,  the  Partnership  was in default on the
Notes.  Fox Capital  Management  Corporation  ("FCMC" or the  "Managing  General
Partner")  contacted the indenture trustee for the Notes regarding this default.
In connection with these conversations, on July 30, 1999 the Partnership entered
into a forbearance  agreement with the indenture  trustee  pursuant to which the
indenture  trustee  agreed not to  exercise  its rights and  remedies  under the
indenture for up to 390 days. In turn, the Partnership  agreed to (a) deliver to
the indenture  trustee for the benefit of the noteholders all of the accumulated
cash  of the  Partnership,  less  certain  reserves  and  anticipated  operating
expenses,  (b) market all of its  properties  for sale, (c) deliver all net cash
proceeds  from any  sales to the  indenture  trustee  until  the Notes are fully
satisfied and (d) comply with the reporting requirements under the indenture. On
March 31, 2003,  the  Partnership  sold the last  remaining  property,  Commerce
Plaza, to an unaffiliated  third party.  The net sales proceeds of approximately
$1,270,000 were delivered to the indenture  trustee to be applied to the amounts
due to the noteholders.

The sale of the Partnership's  last remaining asset did not generate  sufficient
proceeds to pay off the Notes in full. Upon the last payment on the Notes by the
indenture trustee, the Partnership is expected to terminate.

As a result of the  decision  to  liquidate  the  Partnership,  the  Partnership
changed its basis of accounting for its financial  statements to the liquidation
basis of  accounting.  Consequently,  assets have been valued at  estimated  net
realizable  value and liabilities  are presented at their  estimated  settlement
amounts, including estimated costs associated with carrying out the liquidation.
The valuation of assets and liabilities  necessarily requires many estimates and
assumptions  and  there  are  substantial  uncertainties  in  carrying  out  the
liquidation.  The actual  realization  of assets and  settlement of  liabilities
could be higher or lower than amounts  indicated  and is based upon the Managing
General  Partner's  estimates  as of  the  date  of the  consolidated  financial
statements.

Included in liabilities in the statement of net liabilities in liquidation as of
March 31,  2004 is  approximately  $686,000 of costs that the  Managing  General
Partner estimates will be incurred during the period of liquidation based on the
assumption that the liquidation process will be completed by September 30, 2004.
Because the success in  realization  of assets and the settlement of liabilities
is based on the Managing  General  Partner's  best  estimates,  the  liquidation
period may be shorter than projected or it may be extended  beyond the projected
period.

Note B - Transactions with Affiliated Parties

The  Partnership  has no employees  and is  dependent  on the  Managing  General
Partner  and  its  affiliates  for  the  management  and  administration  of all
partnership activities.  The Partnership Agreement provides for certain payments
to affiliates for services and as reimbursement of certain expenses  incurred by
affiliates on behalf of the Partnership.

An  affiliate  of  the  Managing  General  Partner  received   reimbursement  of
accountable  administrative  expenses amounting to approximately $32,000 for the
three months ended March 31, 2003. No such  reimbursements  were paid during the
three months ended March 31, 2004.

Note C - Contingencies

In March 1998, several putative unit holders of limited partnership units of the
Partnership  commenced an action  entitled  Rosalie  Nuanes,  et al. v. Insignia
Financial Group, Inc., et al. (the "Nuanes action") in the Superior Court of the
State of  California  for the  County  of San  Mateo.  The  plaintiffs  named as
defendants,  among others,  the  Partnership,  its Managing  General Partner and
several of their  affiliated  partnerships  and corporate  entities.  The action
purported  to  assert  claims  on  behalf  of a class of  limited  partners  and
derivatively  on behalf  of a number  of  limited  partnerships  (including  the
Partnership)  that are named as nominal  defendants,  challenging,  among  other
things,  the  acquisition  of  interests  in certain  Managing  General  Partner
entities by Insignia Financial Group, Inc.  ("Insignia") and entities that were,
at one  time,  affiliates  of  Insignia;  past  tender  offers  by the  Insignia
affiliates to acquire limited partnership units;  management of the partnerships
by the  Insignia  affiliates;  and the series of  transactions  which  closed on
October 1, 1998 and February 26, 1999 whereby  Insignia and Insignia  Properties
Trust,  respectively,  were merged into AIMCO.  The plaintiffs  sought  monetary
damages and equitable relief, including judicial dissolution of the Partnership.
In addition, during the third quarter of 2001, a complaint (the "Heller action")
was filed  against  the same  defendants  that are named in the  Nuanes  action,
captioned  Heller v.  Insignia  Financial  Group.  On or about  August 6,  2001,
plaintiffs filed a first amended  complaint.  The Heller action was brought as a
purported derivative action, and asserted claims for, among other things, breach
of fiduciary  duty,  unfair  competition,  conversion,  unjust  enrichment,  and
judicial dissolution.

On January 8, 2003,  the parties filed a  Stipulation  of Settlement in proposed
settlement  of the Nuanes  action and the Heller  action.  The  settlement  only
benefits limited partners as of December 20, 2002 in those limited  partnerships
named in the complaint  that are not in the process of being  liquidated or that
have already been  liquidated.  The  Partnership's  limited partners will not be
entitled to any proceeds from the  settlement  since the  Partnership  is in the
process of being liquidated,  but have not compromised any potential claims as a
result of the settlement  and  dismissal.  The  Partnership's  limited  partners
should have received a Notice to  Non-Settling  Persons  during April 2003 which
describes this information in more detail.

On June 13, 2003, the Court granted final approval of the settlement and entered
judgment in both the Nuanes and Heller actions.  On August 12, 2003, an objector
filed an appeal  seeking  to vacate  and/or  reverse  the  order  approving  the
settlement  and  entering  judgment  thereto.  On April 23,  2004,  the Managing
General  Partner  and its  affiliates  filed a response  brief in support of the
settlement  and the  judgment  thereto.  Plaintiffs  have also  filed a brief in
support of the settlement.  Objector is scheduled to file a reply brief no later
than May 13, 2004.

The  Managing  General  Partner  does  not  anticipate  that  any  costs  to the
Partnership,  whether legal or settlement costs,  associated with this case will
be material to the Partnership's overall operations.

Pursuant to a formal order of investigation received by AIMCO on March 29, 2004,
the  Central  Regional  Office of the  United  States  Securities  and  Exchange
Commission is conducting an  investigation  relating to certain  matters.  AIMCO
believes the areas of investigation  include AIMCO's  miscalculated  monthly net
rental  income  figures in third  quarter 2003,  forecasted  guidance,  accounts
payable,  rent concessions,  vendor rebates,  and capitalization of expenses and
payroll.  AIMCO is cooperating  fully.  AIMCO does not believe that the ultimate
outcome  will  have a  material  adverse  effect on its  consolidated  financial
condition or results of  operations  taken as a whole.  Similarly,  the Managing
General Partner does not believe that the ultimate  outcome will have a material
adverse effect on the Partnership's  consolidated financial condition or results
of operations taken as a whole.

ITEM 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

The matters discussed in this report contain certain forward-looking statements,
including, without limitation, statements regarding future financial performance
and the effect of government  regulations.  Actual results may differ materially
from those described in the forward-looking statements and will be affected by a
variety of risks and factors including,  without limitation:  national and local
economic  conditions;  the terms of  governmental  regulations  that  affect the
Registrant and interpretations of those regulations; the competitive environment
in which the Registrant  operates;  litigation,  including costs associated with
defending claims and any adverse  outcomes.  Readers should carefully review the
Registrant's  financial  statements and the notes  thereto,  as well as the risk
factors  described in the documents the Registrant  files from time to time with
the Securities and Exchange Commission.

As of December  31,  1999,  the  Partnership  adopted the  liquidation  basis of
accounting.  The Partnership's  Nonrecourse Promissory Notes (the "Notes") had a
balance of principal and deferred interest of approximately $80,000,000 at their
maturity date of February 15, 1999.  The  Partnership  was unable to satisfy the
Notes at maturity and as a result,  the Partnership was in default on the Notes.
The Managing  General  Partner  contacted  the  indenture  trustee for the Notes
regarding  this default.  In connection  with these  conversations,  on July 30,
1999, the  Partnership  entered into a forbearance  agreement with the indenture
trustee  pursuant to which the  indenture  trustee  agreed not to  exercise  its
rights  and  remedies  under  the  indenture  for up to 390 days.  In turn,  the
Partnership  agreed to (a) deliver to the  indenture  trustee for the benefit of
the  noteholders all of the accumulated  cash of the  Partnership,  less certain
reserves and anticipated  operating  expenses,  (b) market all of its properties
for sale,  (c) deliver  all net cash  proceeds  from any sales to the  indenture
trustee  until the Notes are fully  satisfied  and (d) comply with the reporting
requirements under the indenture.

On March 31, 2003, the Partnership  sold the last remaining  property,  Commerce
Plaza, to an unaffiliated  third party.  The net sales proceeds of approximately
$1,270,000 were delivered to the indenture  trustee to be applied to the amounts
due to the noteholders.

The sale of the Partnership's  last remaining asset did not generate  sufficient
proceeds to pay off the Notes in full. Upon the last payment on the Notes by the
indenture trustee, the Partnership is expected to terminate.

As a result of the  decision  to  liquidate  the  Partnership,  the  Partnership
changed its basis of accounting for its financial  statements to the liquidation
basis of  accounting.  Consequently,  assets have been valued at  estimated  net
realizable  value and liabilities  are presented at their  estimated  settlement
amounts, including estimated costs associated with carrying out the liquidation.
The valuation of assets and liabilities  necessarily requires many estimates and
assumptions  and  there  are  substantial  uncertainties  in  carrying  out  the
liquidation.  The actual  realization  of assets and  settlement of  liabilities
could be higher or lower than amounts  indicated  and is based upon the Managing
General  Partner's  estimates  as of  the  date  of the  consolidated  financial
statements.

Included in liabilities in the statement of net liabilities in liquidation as of
March 31,  2004 is  approximately  $686,000 of costs that the  Managing  General
Partner estimates will be incurred during the period of liquidation based on the
assumption that the liquidation process will be completed by September 30, 2004.
Because the success in  realization  of assets and the settlement of liabilities
is based on the Managing  General  Partner's  best  estimates,  the  liquidation
period may be shorter than projected or it may be extended  beyond the projected
period.

During the three  months  ended March 31,  2004,  net  liabilities  increased by
approximately $388,000. This increase is primarily due to an increase in accrued
interest payable on the Notes and a decrease in cash and cash equivalents.

During the three  months  ended March 31,  2003,  net  liabilities  increased by
approximately  $2,035,000.  This  increase  is  primarily  due to a decrease  in
investment properties and an increase in interest payable on the Notes partially
offset by an increase in cash in the debt trustee escrow  account.  The decrease
in investment  properties and the increase in cash in the debt escrow account is
a result of the sale of Commerce Plaza.

In light of the maturity of the Notes, no distributions were made to the limited
partners for the three month periods ended March 31, 2004 and 2003.

In addition to its indirect  ownership of the Managing  General Partner interest
in the Partnership,  AIMCO owned 108 limited  partnership units (the "Units") in
the Partnership  representing  approximately  0.11% of the outstanding  units at
March 31,  2004.  Affiliates  of the Managing  General  Partner also owned 5,511
(8.24%) of the Partnership's 1985 Nonrecourse Promissory Notes and 1,635 (9.64%)
of the  Partnership's  1986  Nonrecourse  Promissory  Notes at March  31,  2004.
Although  the Managing  General  Partner  owes  fiduciary  duties to the limited
partners of the  Partnership,  the Managing  General Partner also owes fiduciary
duties to AIMCO as its sole stockholder. As a result, the duties of the Managing
General Partner, as managing general partner, to the Partnership and its limited
partners may come into conflict with the duties of the Managing  General Partner
to AIMCO, as its sole stockholder.

ITEM 3.     CONTROLS AND PROCEDURES

(a) Disclosure Controls and Procedures.  The Partnership's management,  with the
participation of the principal executive officer and principal financial officer
of the Managing  General  Partner,  who are the equivalent of the  Partnership's
principal executive officer and principal financial officer,  respectively,  has
evaluated  the  effectiveness  of  the  Partnership's  disclosure  controls  and
procedures (as such term is defined in Rules  13a-15(e) and 15d-15(e)  under the
Securities  Exchange Act of 1934, as amended (the "Exchange Act")) as of the end
of the period covered by this report.  Based on such  evaluation,  the principal
executive  officer  and  principal  financial  officer of the  Managing  General
Partner, who are the equivalent of the Partnership's principal executive officer
and principal  financial officer,  respectively,  have concluded that, as of the
end of such period,  the  Partnership's  disclosure  controls and procedures are
effective.

(b) Internal Control Over Financial  Reporting.  There have not been any changes
in the Partnership's  internal control over financial reporting (as such term is
defined in Rules  13a-15(f)  and  15d-15(f)  under the Exchange  Act) during the
fiscal quarter to which this report relates that have  materially  affected,  or
are reasonably likely to materially affect,  the Partnership's  internal control
over financial reporting.

                           PART II - OTHER INFORMATION


ITEM 1.     LEGAL PROCEEDINGS

In March 1998, several putative unit holders of limited partnership units of the
Partnership  commenced an action  entitled  Rosalie  Nuanes,  et al. v. Insignia
Financial Group, Inc., et al. (the "Nuanes action") in the Superior Court of the
State of  California  for the  County  of San  Mateo.  The  plaintiffs  named as
defendants,  among others,  the  Partnership,  its Managing  General Partner and
several of their  affiliated  partnerships  and corporate  entities.  The action
purported  to  assert  claims  on  behalf  of a class of  limited  partners  and
derivatively  on behalf  of a number  of  limited  partnerships  (including  the
Partnership)  that are named as nominal  defendants,  challenging,  among  other
things,  the  acquisition  of  interests  in certain  Managing  General  Partner
entities by Insignia Financial Group, Inc.  ("Insignia") and entities that were,
at one  time,  affiliates  of  Insignia;  past  tender  offers  by the  Insignia
affiliates to acquire limited partnership units;  management of the partnerships
by the  Insignia  affiliates;  and the series of  transactions  which  closed on
October 1, 1998 and February 26, 1999 whereby  Insignia and Insignia  Properties
Trust,  respectively,  were merged into AIMCO.  The plaintiffs  sought  monetary
damages and equitable relief, including judicial dissolution of the Partnership.
In addition, during the third quarter of 2001, a complaint (the "Heller action")
was filed  against  the same  defendants  that are named in the  Nuanes  action,
captioned  Heller v.  Insignia  Financial  Group.  On or about  August 6,  2001,
plaintiffs filed a first amended  complaint.  The Heller action was brought as a
purported derivative action, and asserted claims for, among other things, breach
of fiduciary  duty,  unfair  competition,  conversion,  unjust  enrichment,  and
judicial dissolution.

On January 8, 2003,  the parties filed a  Stipulation  of Settlement in proposed
settlement  of the Nuanes  action and the Heller  action.  The  settlement  only
benefits limited partners as of December 20, 2002 in those limited  partnerships
named in the complaint  that are not in the process of being  liquidated or that
have already been  liquidated.  The  Partnership's  limited partners will not be
entitled to any proceeds from the  settlement  since the  Partnership  is in the
process of being liquidated,  but have not compromised any potential claims as a
result of the settlement  and  dismissal.  The  Partnership's  limited  partners
should have received a Notice to  Non-Settling  Persons  during April 2003 which
describes this information in more detail.

On June 13, 2003, the Court granted final approval of the settlement and entered
judgment in both the Nuanes and Heller actions.  On August 12, 2003, an objector
filed an appeal  seeking  to vacate  and/or  reverse  the  order  approving  the
settlement  and  entering  judgment  thereto.  On April 23,  2004,  the Managing
General  Partner  and its  affiliates  filed a response  brief in support of the
settlement  and the  judgment  thereto.  Plaintiffs  have also  filed a brief in
support of the settlement.  Objector is scheduled to file a reply brief no later
than May 13, 2004.

The  Managing  General  Partner  does  not  anticipate  that  any  costs  to the
Partnership, whether legal or settlement costs, associated with these cases will
be material to the Partnership's overall operations.

ITEM 2.     EXHIBITS AND REPORTS ON FORM 8-K

            a) Exhibits:

                  Exhibit 3, Agreement of Limited  Partnership,  incorporated by
