NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)





Note A  Basis of Presentation



The accompanying unaudited consolidated financial statements of Angeles Partners XI (the "Partnership" or "Registrant") have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-QSB and Item 310(b) of Regulation S-B.  Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.  In the opinion of Angeles Realty Corporation II (the "Managing General Partner"), all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.  Operating results for the three month period ended March 31, 2006, are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2006. For further information, refer to the consolidated financial statements and footnotes thereto included in the Partnership's Annual Report on Form 10-KSB for the fiscal year ended December 31, 2005. The Managing General Partner is an affiliate of Apartment Investment and Management Company ("AIMCO"), a publicly traded real estate investment trust.



Recent Accounting Pronouncement



In May 2005, the Financial Accounting Standards Board issued SFAS No. 154 Accounting Changes and Error Corrections, which replaces APB Opinion No. 20 and SFAS No. 3, and changes the requirements for the accounting for and reporting of a change in accounting principle. This statement is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. The Partnership adopted SFAS No. 154 effective January 1, 2006. The adoption of SFAS No. 154 did not have a material effect on the Partnerships consolidated financial condition or results of operations.



Note B  Transactions with Affiliated Parties



The Partnership has no employees and depends on the Managing General Partner and its affiliates for the management and administration of all Partnership activities. The Partnership Agreement provides for (i) certain payments to affiliates for services and (ii) reimbursement of certain expenses incurred by affiliates on behalf of the Partnership.



Affiliates of the Managing General Partner receive 5% of gross receipts from the Partnership's property as compensation for providing property management services. The Partnership paid to such affiliates approximately $116,000 and $113,000 for the three months ended March 31, 2006 and 2005, respectively, which is included in operating expenses.



Affiliates of the Managing General Partner charged the Partnership for reimbursement of accountable administrative expenses amounting to approximately $88,000 and $86,000 for the three months ended March 31, 2006 and 2005, respectively, which are included in general and administrative expenses and investment property. The portion of these reimbursements included in investment property for the three months ended March 31, 2006 and 2005 are fees related to construction management services provided by an affiliate of the Managing General Partner of approximately $50,000 and $52,000, respectively. Approximately $27,000 of the accountable administrative expenses are payable to the Managing General Partner and are included in due to affiliates at March 31, 2006. This amount was repaid subsequent to March 31, 2006 from amounts released from a restricted escrow (see Note C).













The Partnership Agreement provides for a fee equal to 7.5% of "net cash flow from operations", as defined in the Partnership Agreement, to be paid to the Managing General Partner for executive and administrative management services. One half of this fee is to be accrued and not paid unless the limited partners have received distributions equal to a 5% cumulative annual return on their adjusted capital investment as defined in the Partnership Agreement. This return criteria has not been met.  During the three months ended March 31, 2006 and 2005 no fees were earned or paid. At March 31, 2006, the Partnership has accrued approximately $21,000 of Partnership management fees, representing one half of the fees earned in 2000, 2001 and 2002 which are included in due to affiliates. This amount will remain accrued until the criteria for payment has been met.



During the three months ended March 31, 2005, an affiliate of the Managing General Partner advanced to the Partnership approximately $78,000 to cover capital improvements at Fox Run Apartments. Additionally, during the remainder of 2005, an affiliate of the Managing General Partner advanced to the Partnership approximately $1,210,000. There were no advances from the Managing General Partner during the three months ended March 31, 2006. Interest was charged at prime plus 2% (9.75% at March 31, 2006) and was approximately $31,000 and $1,000 for the three months ended March 31, 2006 and 2005, respectively. Total advances and accrued interest of approximately $1,371,000 remain unpaid at March 31, 2006 and are included in due to affiliates. Approximately $319,000 of outstanding advances and accrued interest were repaid subsequent to March 31, 2006 from amounts released from a restricted escrow (see Note C).



The Partnership insures its property up to certain limits through coverage provided by AIMCO which is generally self-insured for a portion of losses and liabilities related to workers compensation, property casualty, general liability and vehicle liability. The Partnership insures its property above the AIMCO limits through insurance policies obtained by AIMCO from insurers unaffiliated with the Managing General Partner.  During the three months ended March 31, 2006, the Partnership was charged by AIMCO and its affiliates approximately $145,000 for hazard insurance coverage and fees associated with policy claims administration.  Additional charges will be incurred by the Partnership during 2006 as other insurance policies renew later in the year. The Partnership was charged by AIMCO and its affiliates approximately $104,000 for insurance coverage and fees associated with policy claims administration during the year ended December 31, 2005.



Note C  Subsequent Event



In connection with the December 2001 refinancing of Fox Run Apartments, $625,000 of the net proceeds were placed in a restricted escrow account held by the mortgage lender.  These funds were to be held until the property reached 95% average annual occupancy and maintained that level for three consecutive months. This criteria was met subsequent to March 31, 2006, and the Partnership received $625,000 in funds which were used to fund operations at the property and to partially repay the amount due to affiliates (see Note B).



Note D - 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 captioned Heller v. Insignia Financial Group (the "Heller action") was filed against the same defendants that are named in the Nuanes action. 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 28, 2002, the trial court granted defendants motion to strike the complaint.  Plaintiffs took an appeal from this order.



On January 8, 2003, the parties filed a Stipulation of Settlement in proposed settlement of the Nuanes action and the Heller action. 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 ("Objector") filed an appeal (the Appeal) seeking to vacate and/or reverse the order approving the settlement and entering judgment thereto. On May 4, 2004, the Objector filed a second appeal challenging the courts use of a referee and its order requiring Objector to pay those fees.



On March 21, 2005, the Court of Appeals issued opinions in both pending appeals.  With regard to the settlement and judgment entered thereto, the Court of Appeals vacated the trial courts order and remanded to the trial court for further findings on the basis that the state of the record is insufficient to permit meaningful appellate review.  The matter was transferred back to the trial court on June 21, 2005.  With regard to the second appeal, the Court of Appeals reversed the order requiring the Objector to pay referee fees. With respect to the related Heller appeal, on July 28, 2005, the Court of Appeals reversed the trial courts order striking the first amended complaint.



On August 18, 2005, Objector and his counsel filed a motion to disqualify the trial court based on a peremptory challenge and filed a motion to disqualify for cause on October 17, 2005, both of which were ultimately denied and/or struck by the trial court.  On or about October 13, 2005 Objector filed a motion to intervene and on or about October 19, 2005 filed both a motion to take discovery relating to the adequacy of plaintiffs as derivative representatives and a motion to dissolve the anti-suit injunction in connection with settlement.  On November 14, 2005, Plaintiffs filed a Motion For Further Findings pursuant to the remand ordered by the Court of Appeals. Defendants joined in that motion.  On February 3, 2006, the Court held a hearing on the various matters pending before it and has ordered additional briefing from the parties and Objector.  The parties and Objector submitted one final round of briefing to the Court and the matter has been submitted for the Courts decision.



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.













AIMCO Properties L.P. and NHP Management Company, both affiliates of the Managing General Partner, are defendants in a lawsuit alleging that they willfully violated the Fair Labor Standards Act (FLSA) by failing to pay maintenance workers overtime

for all hours worked in excess of forty per week. The complaint, filed in the United States District Court for the District of Columbia, attempts to bring a collective action under the FLSA and seeks to certify state subclasses in California, Maryland, and the District of Columbia. Specifically, the plaintiffs contend that AIMCO Properties L.P. and NHP Management Company failed to compensate maintenance workers for time that they were required to be "on-call". Additionally, the complaint alleges AIMCO Properties L.P. and NHP Management Company failed to comply with the FLSA in compensating maintenance workers for time that they worked in excess of 40 hours in a week.   In June 2005 the Court conditionally certified the collective action on both the on-call and overtime issues, which allows the plaintiffs to provide notice of the collective action to all non-exempt maintenance workers from August 7, 2000 through the present.  Notices have been sent out to all current and former hourly maintenance workers. Although 1,049 individuals opted-in to the class the defendants will be challenging the eligibility and timeliness of some. Defendants will have the opportunity to move to decertify the collective action with briefing that commences in August.  Because the court denied plaintiffs motion to certify state subclasses, on September 26, 2005, the plaintiffs filed a class action with the same allegations in the Superior Court of California (Contra Costa County), and on November 5, 2005 in Montgomery County Maryland Circuit Court.  The California case has been stayed, while discovery in the Maryland case proceeds. Although the outcome of any litigation is uncertain, AIMCO Properties, L.P. does not believe that the ultimate outcome will have a material adverse effect on its consolidated financial condition or results of operations. 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.



The Partnership is unaware of any other pending or outstanding litigation matters involving it or its investment property that are not of a routine nature arising in the ordinary course of business.



Environmental



Various Federal, state and local laws subject property owners or operators to liability for management, and the costs of removal or remediation, of certain hazardous substances present on a property.  Such laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the release or presence of the hazardous substances.  The presence of, or the failure to manage or remedy properly, hazardous substances may adversely affect occupancy at affected apartment communities and the ability to sell or finance affected properties.  In addition to the costs associated with investigation and remediation actions brought by government agencies, and potential fines or penalties imposed by such agencies in connection therewith, the presence of hazardous substances on a property could result in claims by private plaintiffs for personal injury, disease, disability or other infirmities.  Various laws also impose liability for the cost of removal, remediation or disposal of hazardous substances through a licensed disposal or treatment facility.  Anyone who arranges for the disposal or treatment of hazardous substances is potentially liable under such laws.  These laws often impose liability whether or not the person arranging for the disposal ever owned or operated the disposal facility.  In connection with the ownership, operation and management of its property, the Partnership could potentially be liable for environmental liabilities or costs associated with its property.











Mold



The Partnership is aware of lawsuits against owners and managers of multifamily properties asserting claims of personal injury and property damage caused by the presence of mold, some of which have resulted in substantial monetary judgments or settlements.  The Partnership has only limited insurance coverage for property damage loss claims arising from the presence of mold and for personal injury claims related to mold exposure.  Affiliates of the Managing General Partner have implemented a national policy and procedures to prevent or eliminate mold from its properties and the Managing General Partner believes that these measures will minimize the effects that mold could have on residents.  To date, the Partnership has not incurred any material costs or liabilities relating to claims of mold exposure or to abate mold conditions.  Because the law regarding mold is unsettled and subject to change the Managing General Partner can make no assurance that liabilities resulting from the presence of or exposure to mold will not have a material adverse effect on the Partnerships consolidated financial condition or results of operations.













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; financing risks, including the risk that cash flows from operations may be insufficient to meet required payments of principal and interest; real estate risks, including variations of real estate values and the general economic climate in local markets and competition for tenants in such markets; litigation, including costs associated with prosecuting and defending claims and any adverse outcomes,and possible environmental liabilities. 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.



The Partnership's investment property consists of one apartment complex.  The following table sets forth the average occupancy of the property for the three months ended March 31, 2006 and 2005:



|                       |                   |     
|---------------------- | ----------------- | ----
|                       | Average Occupancy
|Property               | 2006              | 2005
|                       |                   |     
|Fox Run Apartments     | 96%               | 92% 
|Plainsboro, New Jersey |                   |     



The Managing General Partner attributes the increase in average occupancy at Fox Run Apartments to improvement in economic conditions in the local market and increased marketing efforts.



The Partnerships financial results depend upon a number of factors including the ability to attract and maintain tenants at the investment property, interest rates on mortgage loans, costs incurred to operate the investment property, general economic conditions and weather. As part of the ongoing business plan of the Partnership, the Managing General Partner monitors the rental market environment of its investment property to assess the feasibility of increasing rents, maintaining or increasing occupancy levels and protecting the Partnership from increases in expenses. As part of this plan, the Managing General Partner attempts to protect the Partnership from the burden of inflation-related increases in expenses by increasing rents and maintaining a high overall occupancy level. However, the Managing General Partner may use rental concessions and rental rate reductions to offset softening market conditions; accordingly, there is no guarantee that the Managing General Partner will be able to sustain such a plan. Further, a number of factors that are outside the control of the Partnership such as the local economic climate and weather can adversely or positively affect the Partnerships financial results.



Results of Operations



The Partnerships net income for the three months ended March 31, 2006 was approximately $224,000 compared to net income of approximately $55,000 for the corresponding period in 2005. Net income increased for the three months ended March 31, 2006 due to an increase in total revenues and a decrease in total expenses. Total revenues increased largely due to an increase in rental income. Rental income increased due to increases in occupancy and the average rental rate and a decrease in bad debt expense at the Partnerships investment property.















Total expenses decreased due to decreases in property tax and operating expenses, partially offset by an increase in interest and depreciation expenses. Property tax expense decreased due to a decrease in the property tax rate during the second quarter of 2005.  Operating expense decreased primarily due to a decrease in maintenance expense partially offset by increases in property and administrative expenses. Maintenance expense decreased due to decreases in heating, venting, and air conditioning parts and supplies, electrical and plumbing supplies and interior building improvements.  Property expense increased primarily due to increases in utilities. Administrative expense increased due to increases in resident eviction costs and business  licenses and permits. Interest expense increased for the three months ended March 31, 2006 as a result of an increase in interest on advances from an affiliate of the Managing General Partner, partially offset by a decrease in interest expense on the mortgage encumbering the investment property due to scheduled principal payments which reduced the carrying balance of the mortgage. Depreciation expense increased as a result of property improvements and replacements placed into service over the past twelve months.



Included in general and administrative expenses are the New Jersey Partnership tax, the cost of services included in the management reimbursements to the Managing General Partner as allowed under the Partnership Agreement and costs associated with the quarterly and annual communications with investors and regulatory agencies and the annual audit required by the Partnership Agreement.



Liquidity and Capital Resources



At March 31, 2006 the Partnership had cash and cash equivalents of approximately $133,000 compared to approximately $79,000 at March 31, 2005. Cash and cash equivalents decreased approximately $155,000 since December 31, 2005 due to approximately $515,000 and $273,000 of cash used in investing and financing activities, respectively, partially offset by approximately $633,000 of cash provided by operating activities. Cash used in investing activities consisted of property improvements and replacements.  Cash used in financing activities consisted of principal payments on the mortgage encumbering the Partnerships property. The Partnership invests its working capital reserves in interest-bearing accounts.



The sufficiency of existing liquid assets to meet future liquidity and capital expenditure requirements is directly related to the level of capital expenditures required at the property to adequately maintain the physical assets and other operating needs of the Partnership and to comply with federal, state, and local legal and regulatory requirements. The Managing General Partner monitors developments in the area of legal and regulatory compliance.  For example, the Sarbanes-Oxley Act of 2002 mandates or suggests additional compliance measures with regard to governance, disclosure, audit and other areas. In light of these changes, the Partnership expects that it will incur higher expenses related to compliance.



During the three months ended March 31, 2006, the Partnership completed approximately $453,000 of capital improvements at Fox Run Apartments, primarily consisting of floor covering, water heater and appliance replacements. These improvements were funded from operating cash flow. The Partnership regularly evaluates the capital improvement needs of the property. While the Partnership has no material commitments for property improvements and replacements, certain routine capital expenditures are anticipated during 2006. Such capital expenditures will depend on the physical condition of the property as well as anticipated cash flow generated by the property. To the extent that capital improvements are completed, the Partnerships distributable cash flow, if any, may be adversely affected at least in the short term.



Subsequent to March 31, 2006, the Partnership received $625,000 in restricted escrow funds from the mortgage lender as a result of average occupancy benchmarks being achieved.















The Partnerships assets are thought to be generally sufficient for any near term needs (exclusive of capital improvements) of the Partnership. The mortgage indebtedness encumbering Fox Run Apartments of approximately $30,927,000 is being amortized over 20 years and matures in December 2021, at which time it is scheduled to be fully amortized.



The Partnership made no distributions for the three months ended March 31, 2006 and 2005. Future cash distributions will depend on the levels of net cash generated from operations, the timing of the sale of the property and/or refinancing. The Partnerships cash available for distribution is reviewed on a monthly basis. In light of the amounts accrued and payable to affiliates of the Managing General Partner at March 31, 2006, there can be no assurance that the Partnership will generate sufficient funds from operations, after planned capital improvement expenditures, to permit any distributions to its partners in 2006 or subsequent periods.



Other



In addition to its indirect ownership of the general partner interests in the Partnership, AIMCO and its affiliates owned 28,381 limited partnership units (the "Units") in the Partnership representing 71.62% of the outstanding Units at March 31, 2006.  A number of these Units were acquired pursuant to tender offers made by AIMCO or its affiliates.  It is possible that AIMCO or its affiliates will acquire additional Units in exchange for cash or a combination of cash and units in AIMCO Properties, L.P, the operating partnership of AIMCO, either through private purchases or tender offers. Pursuant to the Partnership Agreement, unitholders holding a majority of the Units are entitled to take action with respect to a variety of matters that include, but are not limited to, voting on certain amendments to the Partnership Agreement and voting to remove the Managing General Partner. As a result of its ownership of 71.62% of the outstanding Units, AIMCO and its affiliates are in a position to control all voting decisions with respect to the Partnership. 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.



Critical Accounting Policies and Estimates



The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States, which require the Partnership to make estimates and assumptions.  The Partnership believes that of its significant accounting policies, the following may involve a higher degree of judgment and complexity.



Impairment of Long-Lived Asset



Investment property is recorded at cost, less accumulated depreciation, unless the carrying amount of the asset is not recoverable.  If events or circumstances indicate that the carrying amount of the property may not be recoverable, the Partnership will make an assessment of its recoverability by comparing the carrying amount to the Partnerships estimate of the undiscounted future cash flows, excluding interest charges, of the property.   If the carrying amount exceeds the aggregate undiscounted future cash flows, the Partnership would recognize an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property.















Real property investment is subject to varying degrees of risk.  Several factors may adversely affect the economic performance and value of the Partnerships investment property.  These factors include, but are not limited to, general economic climate; competition from other apartment communities and other housing options; local conditions, such as loss of jobs or an increase in the supply of apartments that might adversely affect apartment occupancy or rental rates; changes in governmental regulations and the related cost of compliance; increases in operating costs (including real estate taxes) due to inflation and other factors, which may not be offset by increased rents; and changes in tax laws and housing laws, including the enactment of rent control laws or other laws regulating multi-family housing.  Any adverse changes in these factors could cause impairment of the Partnerships asset.



Revenue Recognition



The Partnership generally leases apartment units for twelve-month terms or less.  The Partnership will offer rental concessions during particularly slow months or in response to heavy competition from other similar complexes in the area.  Rental income attributable to leases, net of any concessions, is recognized on a straight-line basis over the term of the lease.  The Partnership evaluates all accounts receivable from residents and establishes an allowance, after the application of security deposits, for accounts greater than 30 days past due on current tenants and all receivables due from former tenants.



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 captioned Heller v. Insignia Financial Group (the "Heller action") was filed against the same defendants that are named in the Nuanes action. 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 28, 2002, the trial court granted defendants motion to strike the complaint.  Plaintiffs took an appeal from this order.



On January 8, 2003, the parties filed a Stipulation of Settlement in proposed settlement of the Nuanes action and the Heller action. 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 ("Objector") filed an appeal (the Appeal) seeking to vacate and/or reverse the order approving the settlement and entering judgment thereto. On May 4, 2004, the Objector filed a second appeal challenging the courts use of a referee and its order requiring Objector to pay those fees.



On March 21, 2005, the Court of Appeals issued opinions in both pending appeals.  With regard to the settlement and judgment entered thereto, the Court of Appeals vacated the trial courts order and remanded to the trial court for further findings on the basis that the state of the record is insufficient to permit meaningful appellate review.  The matter was transferred back to the trial court on June 21, 2005.  With regard to the second appeal, the Court of Appeals reversed the order requiring the Objector to pay referee fees. With respect to the related Heller appeal, on July 28, 2005, the Court of Appeals reversed the trial courts order striking the first amended complaint.



On August 18, 2005, Objector and his counsel filed a motion to disqualify the trial court based on a peremptory challenge and filed a motion to disqualify for cause on October 17, 2005, both of which were ultimately denied and/or struck by the trial court.  On or about October 13, 2005 Objector filed a motion to intervene and on or about October 19, 2005 filed both a motion to take discovery relating to the adequacy of plaintiffs as derivative representatives and a motion to dissolve the anti-suit injunction in connection with settlement.  On November 14, 2005, Plaintiffs filed a Motion For Further Findings pursuant to the remand ordered by the Court of Appeals. Defendants joined in that motion.  On February 3, 2006, the Court held a hearing on the various matters pending before it and has ordered additional briefing from the parties and Objector.  The parties and Objector submitted one final round of briefing to the Court and the matter has been submitted for the Courts decision.













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.



AIMCO Properties L.P. and NHP Management Company, both affiliates of the Managing General Partner, are defendants in a lawsuit alleging that they willfully violated the Fair Labor Standards Act (FLSA) by failing to pay maintenance workers overtime for all hours worked in excess of forty per week. The complaint, filed in the United States District Court for the District of Columbia, attempts to bring a collective action under the FLSA and seeks to certify state subclasses in California, Maryland, and the District of Columbia. Specifically, the plaintiffs contend that AIMCO Properties L.P. and NHP Management Company failed to compensate maintenance workers for time that they were required to be "on-call". Additionally, the complaint alleges AIMCO Properties L.P. and NHP Management Company failed to comply with the FLSA in compensating maintenance workers for time that they worked in excess of 40 hours in a week.   In June 2005 the Court conditionally certified the collective action on both the on-call and overtime issues, which allows the plaintiffs to provide notice of the collective action to all non-exempt maintenance workers from August 7, 2000 through the present.  Notices have been sent out to all current and former hourly maintenance workers. Although 1,049 individuals opted-in to the class the defendants will be challenging the eligibility and timeliness of some. Defendants will have the opportunity to move to decertify the collective action with briefing that commences in August.  Because the court denied plaintiffs motion to certify state subclasses, on September 26, 2005, the plaintiffs filed a class action with the same allegations in the Superior Court of California (Contra Costa County), and on November 5, 2005 in Montgomery County Maryland Circuit Court.  The California case has been stayed, while discovery in the Maryland case proceeds. Although the outcome of any litigation is uncertain, AIMCO Properties, L.P. does not believe that the ultimate outcome will have a material adverse effect on its consolidated financial condition or results of operations. 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.
