EXPLANATORY NOTE
This filing combines the reports on Form 10-Q for the quarterly period ended September 30, 2017,March 31, 2018, of Apartment Investment and Management Company, or Aimco, and AIMCO Properties, L.P., or the Aimco Operating Partnership. Where it is important to distinguish between the two entities, we refer to them specifically. Otherwise, references to “we,” “us” or “our” mean, collectively, Aimco, the Aimco Operating Partnership and their consolidated entities.
Aimco, a Maryland corporation, is a self-administered and self-managed real estate investment trust, or REIT. Aimco, through wholly-owned subsidiaries, is the general and special limited partner of, and as of September 30, 2017,March 31, 2018, owned a 95.5%95.4% ownership interest in the common partnership units of, the Aimco Operating Partnership. The remaining 4.5%4.6% interest is owned by limited partners. As the sole general partner of the Aimco Operating Partnership, Aimco has exclusive control of the Aimco Operating Partnership’s day-to-day management.
The Aimco Operating Partnership holds all of Aimco’s assets and manages the daily operations of Aimco’s business. Pursuant to the Aimco Operating Partnership agreement, Aimco is required to contribute to the Aimco Operating Partnership any assets, which it may acquire including all proceeds from the offerings of its securities. In exchange for the contribution of these assets, Aimco receives additional interests in the Aimco Operating Partnership with similar terms (e.g., if Aimco contributes proceeds of a stock offering, Aimco receives partnership units with terms substantially similar to the stock issued by Aimco).
We believe combining the periodic reports of Aimco and the Aimco Operating Partnership into this single report provides the following benefits:
We present our business as a whole, in the same manner our management views and operates the business;
We eliminate duplicative disclosure and provide a more streamlined and readable presentation because a substantial portion of the disclosures apply to both Aimco and the Aimco Operating Partnership; and
We save time and cost through the preparation of a single combined report rather than two separate reports.
We operate Aimco and the Aimco Operating Partnership as one enterprise, the management of Aimco directs the management and operations of the Aimco Operating Partnership, and the members of the Board of Directors of Aimco are identical to those of the Aimco Operating Partnership.
We believe it is important to understand the few differences between Aimco and the Aimco Operating Partnership in the context of how Aimco and the Aimco Operating Partnership operate as a consolidated company. Aimco has no assets or liabilities other than its investment in the Aimco Operating Partnership. Also, Aimco is a corporation that issues publicly traded equity from time to time, whereas the Aimco Operating Partnership is a partnership that has no publicly traded equity. Except for the net proceeds from stock offerings by Aimco, which are contributed to the Aimco Operating Partnership in exchange for additional limited partnership interests (of a similar type and in an amount equal to the shares of stock sold in the offering), the Aimco Operating Partnership generates all remaining capital required by its business. These sources include the Aimco Operating Partnership’s working capital, net cash provided by operating activities, borrowings under its revolving credit facility, the issuance of debt and equity securities, including additional partnership units, and proceeds received from the sale of apartment communities.
Equity, partners’ capital and noncontrolling interests are the main areas of difference between the condensed consolidated financial statements of Aimco and those of the Aimco Operating Partnership. Interests in the Aimco Operating Partnership held by entities other than Aimco, which we refer to as OP Units, are classified within partners’ capital in the Aimco Operating Partnership’s financial statements and as noncontrolling interests in Aimco’s financial statements.
To help investors understand the differences between Aimco and the Aimco Operating Partnership, this report provides: separate condensed consolidated financial statements for Aimco and the Aimco Operating Partnership; a single set of condensed consolidated notes to such financial statements that includes separate discussions of each entity’s stockholders’ equity or partners’ capital, as applicable; and a combined Management’s Discussion and Analysis of Financial Condition and Results of Operations section that includes discrete information related to each entity, where appropriate.
This report also includes separate Part I, Item 4. Controls and Procedures sections and separate Exhibits 31 and 32 certifications for Aimco and the Aimco Operating Partnership in order to establish that the requisite certifications have been made and that Aimco and the Aimco Operating Partnership are both compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and 18 U.S.C. §1350.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2017March 31, 2018
(Unaudited)

Note 1 — Organization
Apartment Investment and Management Company, or Aimco, is a Maryland corporation incorporated on January 10, 1994. Aimco is a self-administered and self-managed real estate investment trust, or REIT. AIMCO Properties, L.P., or the Aimco Operating Partnership, is a Delaware limited partnership formed on May 16, 1994, to conduct our business, which is focused on the ownership, management, redevelopment and limited development of quality apartment communities located in some of the largest markets in the United States.
Aimco, through its wholly-owned subsidiaries, AIMCO-GP, Inc. and AIMCO-LP Trust, owns a majority of the ownership interests in the Aimco Operating Partnership. Aimco conducts all of its business and owns all of its assets through the Aimco Operating Partnership. Interests in the Aimco Operating Partnership that are held by limited partners other than Aimco are referred to as OP Units. OP Units include common partnership units, and high performance partnership units, which we refer to as common OP Units, as well as partnership preferred units, which we refer to as preferred OP Units. As of September 30, 2017,March 31, 2018, after eliminations for units held by consolidated subsidiaries, the Aimco Operating Partnership had 164,459,517164,881,653 common partnership units and equivalents outstanding. As of September 30, 2017,March 31, 2018, Aimco owned 157,023,314157,326,117 of the common partnership units (95.5%(95.4% of the common partnership units and equivalents)units) of the Aimco Operating Partnership and Aimco had outstanding an equal number of shares of its Class A Common Stock, which we refer to as Common Stock.
Except as the context otherwise requires, “we,” “our” and “us” refer to Aimco, the Aimco Operating Partnership and their consolidated subsidiaries, collectively.
As of September 30, 2017,March 31, 2018, we owned an equity interest in 141134 apartment communities with 39,18437,228 apartment homes in our real estateReal Estate portfolio. Our Real Estate portfolio which comprises our reportable segment, is diversified by both price point and geography and consists primarily of market rate apartment communities in which we own a substantial interest. We consolidated 137130 of these apartment communities with 39,04237,086 apartment homes.homes and these communities comprise our reportable segment.
As of September 30, 2017,March 31, 2018, we also ownedheld nominal ownership positions in partnerships holdingthat own 46 low-income housing tax credit apartment communities with 6,898 apartment homes. We provide services to these partnerships and receive fees and other payments in return. Our relationship with these partnerships is different than real estate ownership and is better described as an asset management business, or Asset Management. In accordance with accounting principles generally accepted in the United States of America, or GAAP, we are required to consolidate partnerships owning an aggregate of 39 apartment communities with 6,211 apartment homes.
In April 2018, we announced the planned sale of our Asset Management business, as well as the sale of four affordable communities included in our Real Estate portfolio.
Note 2 — Basis of Presentation and Summary of Significant Accounting Policies
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with such rules and regulations, although management believes the disclosures are adequate to prevent the information presented from being misleading. In the opinion of management, all adjustments (consisting of normal recurring items) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2017,March 31, 2018, are not necessarily indicative of the results that may be expected for the year ending December 31, 2017.2018.
The balance sheets of Aimco and the Aimco Operating Partnership at December 31, 2016,2017, have been derived from their respective audited financial statements at that date, but do not include all of the information and disclosures required by GAAP for complete financial statements. For further information, refer to the financial statements and notes thereto included in Aimco’s and the Aimco Operating Partnership’s combined Annual Report on Form 10-K for the year ended December 31, 2016.2017. Except where indicated, the footnotes refer to both Aimco and the Aimco Operating Partnership.
Effective in 2017, we modified our condensed consolidated balance sheets to present the assets and liabilities of consolidated partnerships served by our Asset Management business separately from those amounts relating to our Real Estate portfolio. We have similarly modified our condensed consolidated statements of operations to present separately the rental and other property

revenues and property operating expenses of consolidated partnerships served by our Asset Management business. We have reclassified these items in the condensed consolidated balance sheets as of December 31, 2016, and in the condensed consolidated statements of operations for the three and nine months ended September 30, 2016, to conform to the current presentation. These reclassifications had no effect on previously reported total assets, total liabilities or net income amounts.
Principles of Consolidation
Aimco’s accompanying condensed consolidated financial statements include the accounts of Aimco, the Aimco Operating Partnership, and their consolidated subsidiaries. The Aimco Operating Partnership’s condensed consolidated financial statements include the accounts of the Aimco Operating Partnership and its consolidated subsidiaries, including partnerships served by our Asset Management business (see note Note 8). All significant intercompany balances and transactions have been eliminated in consolidation.
Interests in the Aimco Operating Partnership that are held by limited partners other than Aimco are reflected in Aimco’s accompanying condensed consolidated balance sheets as noncontrolling interests in the Aimco Operating Partnership. Interests in partnerships consolidated by the Aimco Operating Partnership that are held by third parties are reflected in our accompanying condensed consolidated balance sheets as noncontrolling interests in consolidated real estate partnerships.
Temporary Equity and Partners’ Capital
The following table presents a reconciliation of the Aimco Operating Partnership’s Preferredpreferred OP Units from December 31, 20162017 to September 30, 2017.March 31, 2018. The Preferredpreferred OP Units may be redeemed at the holders’ option (as further discussed in Note 5), and are therefore are presented within temporary equity in Aimco’s condensed consolidated balance sheets and within temporary capital in the Aimco Operating Partnership’s condensed consolidated balance sheets (in thousands).

Use of Estimates
The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts included in the financial statements and accompanying notes thereto. Actual results could differ from those estimates.
Accounting Pronouncements Adopted in the Current Year
Effective April 1, 2017, we elected to adopt early the new accounting standard that revised the GAAP definition of a business. Under the new standard we expect apartment communities will no longer be considered businesses in most acquisitions and dispositions. Under the new standard, transaction costs incurred related to the acquisition of real estate operations will be capitalized as a cost of the acquisition. Additionally, we will no longer allocate goodwill to apartment communities for purposes of calculating gains or losses upon sale. We have applied the new standard prospectively to transactions occurring after April 1, 2017. This standard did not have a significant effect on our financial condition or results of operations.
Effective January 1, 2017, we adopted a new standard issued by the Financial Accounting Standards Board, or FASB, that simplifies the accounting for the income tax consequences of intercompany transfers of assets. Previously, the recognition within the statement of operations of income tax expense or benefit resulting from an intercompany transfer of assets did not occur until the assets affect GAAP income or loss, for example, through depreciation, impairment or upon the sale of the asset to a third party. Under the new standard, an entity recognizes the income tax expense or benefit from an intercompany transfer of assets when the transfer occurs. We have applied this change on a modified retrospective basis and recorded a cumulative effect adjustment to retained earnings of $65.7 million as of January 1, 2017, representing accumulated unrecognized tax expense from intercompany transfers between the Aimco Operating Partnership and TRS entities. Such amounts were included in other assets within our consolidated balance sheets at December 31, 2016.
Also effective January 1, 2017, we adopted guidance that simplifies the accounting for share-based compensation. Under prior practice, tax benefits in excess of those associated with compensation cost recognized in accordance with GAAP, or windfalls, were recorded in equity and tax deficiencies were recorded in equity until previous windfalls had been recouped and then recognized

in earnings. Under the new guidance, all of the tax effects related to share-based compensation are recognized through earnings. This guidance is applied to all windfalls and tax deficiencies resulting from settlements occurring after January 1, 2017. The new guidance also requires windfalls to be recorded in the period the related transaction triggering tax consequences, such as an exercise of stock options or vesting of restricted shares, occurs. This change in timing of recognition has been applied on a modified retrospective basis. We did not record a cumulative effect adjustment to opening retained earnings on the date of adoption as there were no accumulated windfalls recorded in equity. Compared to prior periods, we may experience incremental volatility in income tax benefit or expense resulting from the recognition in earnings of windfall benefits or deficiencies upon the exercise of stock options and vesting of restricted shares.
Recent Accounting PronouncementsIncome Taxes
As discussed in Note 29 to the consolidated financial statements in Item 8 of our Form 10-K for the year ended December 31, 2016, the FASB issued new standards that affect2017, we have not completed our accounting for revenuethe tax effects of the enactment of the Tax Cuts and Jobs Act in late December 2017. During the three months ended March 31, 2018, we recognized a measurement period adjustment to reduce by $11.3 million an estimated valuation allowance recognized as of December 31, 2017. During the three months ended March 31, 2018, we also recognized an offsetting valuation allowance resulting from contracts with customers and that arean intercompany transfer of assets related to the Asset Management business. These adjustments had no net effect on our results of operations or effective for us ontax rate.
Accounting Pronouncements Adopted in the Current Year
Effective January 1, 2018. The FASB also issued2018, we adopted a new standard onissued by the Financial Accounting Standards Board, or FASB, that affects accounting for revenue. Under this new standard, revenue is generally recognized when an entity has transferred control of goods or services to a customer for an amount reflecting the consideration to which the entity expects to be entitled for such exchange. In evaluating the contracts we enter into in the ordinary course of business, substantially all of our revenue is generated by lease agreements, which will continue to be subject to existing GAAP until 2019, when we will adopt the new lease accounting which isstandard.
The new revenue standard also introduced new guidance for accounting for other income, including how we measure gains or losses on the sale of real estate. We adopted the new standard using the modified retrospective transition method effective for Aimco on January 1, 2019,2018, with early adoption permitted.no effect on our results of operations or financial position.
Effective January 1, 2018, we also adopted new standards issued by the FASB that affect the presentation and disclosure of the statements of cash flows. We are now required to present combined inflows and outflows of cash, cash equivalents, and restricted cash in the consolidated statement of cash flows. Previously our consolidated statements of cash flows presented transfers between restricted and unrestricted cash accounts as operating, financing, and investing cash activities depending upon the required or intended purpose for the restricted funds. The new guidance also requires debt prepayment and other extinguishment related payments to be classified as financing activities. We previously classified such payments as operating activities. We have substantially completedrevised our evaluationcondensed consolidated statements of these standardscash flows for the three months ended March 31, 2017 to conform to this

presentation, and do not expect our adoption will have a significantthe effect onof the timing or amount of revenue or lease income we recognize on an ongoing basis. However,revisions to net cash flows from operating and investing activities as previously reported for three months ended March 31, 2017 are summarized in circumstances where we are a lessee, primarily in a limited population of ground leases and leases of corporate office space, we will be required to recognize right of use assets and related lease liabilities within our consolidated balance sheets. We expect the timing and amount of expense for these leases will remain unchanged unless modified prior to their contractual termination dates.following table (in thousands):

Note 3 — Significant Transactions, Dispositions of Apartment Communities and Assets Held for Sale
Reacquisition of Limited Partner Interest in Palazzo Joint Venture and Term Loan
On June 30, 2017, we reacquired for $451.5 million, the 47% noncontrolling limited partner interest in the Palazzo joint venture, which owns three communities with a total of 1,382 apartment homes located in Los Angeles, California. We assumed $140.5 million of the noncontrolling interest partner’s share of existing non-recourse property-level debt and paid $311.0 million in cash consideration, which was funded by short-term borrowings we expect to repay using proceeds from apartment community sales. We now own all of the interests in the Palazzo joint venture and its underlying apartment communities. Prior to the transaction, we consolidated into our financial statements the joint venture and underlying apartment communities, therefore this transaction has been accounted for as an equity transaction. In accordance with GAAP, we recognized the $155.6 million of consideration paid in excess of the noncontrolling interest balance as a reduction of additional paid-in capital within Aimco’s equity and the Aimco Operating Partnership’s partners capital.
On June 30, 2017, we entered into a second amended and restated senior secured credit agreement, or the Credit Agreement. The Credit Agreement continues our existing $600.0 million revolving loan facility with consistent terms and provides for a $250.0 million term loan, which we used to fund a portion of the Palazzo reacquisition. The term loan matures on June 30, 2018, includes a one-year extension option, subject to the satisfaction of customary conditions, and currently bears interest at 30-day LIBOR plus 1.35%. We paid lender and other fees of $1.0 million in connection with the term loan, which have been deferred and will be recognized as additional interest over the duration of the term loan.
DispositionsAcquisition of Apartment Communities
During the ninethree months ended September 30, 2017, partnerships served byMarch 31, 2018, we purchased for $160.0 million Bent Tree Apartments, a 748-apartment home community in Fairfax County, Virginia. The purchase price, plus $1.0 million of capitalized transaction costs, was allocated as follows: $47.0 million to land; $113.0 million to buildings and improvements; and $1.0 million to other items.
Subsequent to March 31, 2018, we entered into a transaction to acquire six apartment communities in the Asset Management businessPhiladelphia area for a stated purchase price of $445.0 million. The portfolio includes 1,006 existing apartment homes, 110 apartment homes under construction, and 185,000 square feet of office and retail space. The acquisition will be funded initially through taking title subject to $290.0 million of non-recourse property debt, issuance of $90.0 million in common OP Units valued in the transaction at their estimated net asset value per unit (approximately 1.7 million common OP Units), and payment of $65.0 million in cash. In accordance with GAAP, the portion of the purchase price attributed to the common OP Units issued will be valued at the closing price of Aimco’s common stock on the dates of issuance.
On May 1, 2018, we completed the acquisition of four of the six apartment communities including 665 apartment homes and 153,000 square feet of office and retail space. We anticipate the acquisition of the fifth apartment community during the summer of 2018 and the acquisition of the final apartment community upon completion of construction, expected in the first half of 2019.
Dispositions of Apartment Communities and Assets Held for Sale
During the three months ended March 31, 2018, we sold twothree apartment communities with a total of 252513 apartment homes for a gain on disposition of $50.6 million, net of income tax, and gross proceeds of $71.9 million resulting in gains$64.6 million in net proceeds to us. Two of $2.6these communities are located in southern Virginia and one is located in suburban Maryland.
During the three months ended March 31, 2018, we sold our interests in the entities owning the La Jolla Cove property in settlement of legal actions filed in 2014 by a group of disappointed buyers who had hoped to acquire the property. We provided seller financing with a stated value of $48.6 million and related tax expensereceived net cash proceeds of $0.9 million.approximately $5.0 million in the sale.
We are currentlyIn addition to the apartment communities we sold during the periods presented, from time to time we may be marketing for sale certain apartment communities that are inconsistent with our long-term investment strategy. Additionally, the consolidated partnerships served by our Asset Management business periodically evaluates for sale certain of their apartment communities. At the end of each reporting period, we evaluate whether any consolidated apartmentsuch communities meet the criteria to be classified as held for sale. As of September 30, 2017,March 31, 2018, no apartment communities were classified as held for sale.
Napico Disposition
In 2012,April 2018, we soldentered into a binding agreement to sell for $590.0 million our Asset Management business and four affordable communities included in our Real Estate portfolio. We expect to close this transaction during the Napico business. The transaction was primarily seller-financed,third quarter of 2018. After payment of closing costs and repayment of property level debt encumbering the associated notes were scheduledHunters Point apartment communities, net proceeds are expected to be repaid from the operation and liquidation of the Napico business and were collateralized by the buyer’s interests in the portfolio. In 2016, the buyer paid the two seller-financed notes in full. At that time we maintained continuing involvement related to preexisting guarantees of property-level debt for two communities. In accordance with GAAP, we deferred recognition of the sale of these communities until the guarantees were released. In September 2017, the owner refinanced the final mortgage, resulting

in the release of our remaining guarantee, which allowed us to transfer our nominal general partner interest in the property to the buyer.
Accordingly, we reduced other assets and accrued liabilities and other by $34.5 million and $38.4 million, respectively, and recognized a gain of $7.1 million, net of tax, in other, net on our condensed consolidated statement of operations for the three and nine months ended September 30, 2017.approximately $512.0 million.
Note 4 — Commitments and Contingencies
Commitments
In connection with our redevelopment, development and capital improvement activities, we have entered into various construction-related contracts and we have made commitments to complete redevelopment of certain apartment communities, pursuant to financing or other arrangements. As of September 30, 2017,March 31, 2018, our commitments related to these capital activities totaled approximately $96.2$160.0 million, most of which we expect to incur during the next 12 months.
We enter into certain commitments for future purchases of goods and services in connection with the operations of our apartment communities. Those commitments generally have terms of one year or less and reflect expenditure levels comparable to our historical expenditures.

Tax Credit Arrangements
For various consolidated partnerships served by our Asset Management business, we are required to manage the partnerships and related apartment communities in compliance with various laws, regulations and contractual provisions that apply to historic and low-income housing tax credit syndication arrangements. In some instances, noncompliance with applicable requirements could result in projected tax benefits not being realized by the limited partners in these partnerships and would require a refund or reduction of investor capital contributions, which are reported as deferred income in our condensed consolidated balance sheets, until such time as our obligation to deliver tax benefits is relieved. The remaining compliance periods forIn connection with the tax credit syndication arrangements range from less than one year to eight years. We do not anticipate that any material refunds or reductionsexpected third quarter sale of investor capital contributionsour Asset Management business, this obligation will be required in connection with these arrangements.assumed by the purchaser.
Income Taxes
In 2014, the Internal Revenue Service initiated an audit of the Aimco Operating Partnership’s 2011 and 2012 tax years. We do not believe the audit will have any material effect on our unrecognized tax benefits, financial condition or results of operations.
Legal Matters
In addition to the matters described below, we are a party to various legal actions and administrative proceedings arising in the ordinary course of business, some of which are covered by our general liability insurance program, and none of which we expect to have a material adverse effect on our consolidated financial condition, results of operations or cash flows.
Limited Partnerships
In connection with our acquisitions of interests in real estate partnerships, we are sometimes subject to legal actions, including allegations that such activities may involve breaches of fiduciary duties to the partners of such real estate partnerships or violations of the relevant partnership agreements. We may incur costs in connection with the defense or settlement of such litigation. We believe that we comply with our fiduciary obligations and relevant partnership agreements. Although the outcome of any litigation is uncertain, we do not expect any such legal actions to have a material adverse effect on our consolidated financial condition, results of operations or cash flows.
La Jolla Cove Litigation
We are a defendant in a lawsuit filed by a group of disappointed buyers that contend we interfered with their allegedly superior right to acquire the La Jolla Cove property. The case, pending in state court in California, is in fact discovery at this stage. The case is set for jury trial in February 2018.  Although the outcome of this litigation is uncertain, we do not believe its resolution will have a material adverse effect on our consolidated financial condition, results of operations, or cash flows.
Environmental
Various federal, state and local laws subject apartment community owners or operators to liability for management, and the costs of removal or remediation, of certain potentially hazardous materials that may be present in the land or buildings of an apartment community. Such laws often impose liability without regard to fault or whether the owner or operator knew of, or was

responsible for, the presence of such materials. The presence of, or the failure to manage or remediate properly, these materials may adversely affect occupancy at such apartment communities as well as the ability to sell or finance such apartment communities. In addition, governmental agencies may bring claims for costs associated with investigation and remediation actions. Moreover, private plaintiffs may potentially make claims for investigation and remediation costs they incur or for personal injury, disease, disability or other infirmities related to the alleged presence of hazardous materials. In addition to potential environmental liabilities or costs associated with our current apartment communities, we may also be responsible for such liabilities or costs associated with communities we acquire or manage in the future, or apartment communities we no longer own or operate.
We are engaged in discussions with the Environmental Protection Agency, or EPA, and the Indiana Department of Environmental Management, or IDEM, regarding contaminated groundwater in a residential area in the vicinity of an Indiana apartment community that has not been owned by us since 2008. The contamination allegedly derives from a dry cleaner that operated on our former property, prior to our ownership. We have undertaken a voluntary remediation of the dry cleaner contamination under IDEM’s oversight, and in previous years accrued our share of the then-estimated cleanup and abatement costs. In 2016, EPA listed our former community and a number of residential communities in the vicinity on the National Priorities List, or NPL (i.e. as a Superfund site), and IDEM has formally sought to terminate us from the voluntary remediation program. We continue discussions with both agencies on potential long-term solutions. We have filed a formal appeal of the EPA listing and the IDEM termination of us from the voluntary remediation program. Although the outcome of these processes are uncertain, we do not expect their resolution to have a material adverse effect on our consolidated financial condition, results of operations or cash flows.
We also have been contacted by regulators and the current owner of a property in Lake Tahoe, California, regarding environmental issues allegedly stemming from the historic operation of a dry cleaner. An entity owned by us was the former general partner of a now-dissolved partnership that previously owned a site that was used for dry cleaning. That entity and the current property owner have been remediating the dry cleaner site since 2009, under the oversight of the Lahontan Regional Water Quality Control Board, or Lahontan. In 2016,May 2017, Lahontan sent us, the current property owner, andissued a former operator of the dry cleaner drafts of a proposedfinal cleanup and abatement order that if entered as drafted, would have required all threenames four potentially-responsible parties, acknowledges that there may be additional responsible parties, and requires the named parties to perform additional groundwater investigation and corrective actions with respect to onsite and offsite contamination. After review of comments from us, Lahontan issued a final order in May 2017. The final order adds one more potentially-responsible party, acknowledges that there may be additional responsible parties, and narrows (as compared to earlier drafts) the scope of work. We are appealing the final order while simultaneously complying with it. Although the outcome of this process is uncertain, we do not expect its resolution to have a material adverse effect on our consolidated financial condition, results of operations or cash flows.
We have determined that our legal obligations to remove or remediate certain potentially hazardous materials may be conditional asset retirement obligations, as defined in GAAP. Except in limited circumstances where the asset retirement activities are expected to be performed in connection with a planned construction project or apartment community casualty, we believe that the fair value of our asset retirement obligations cannot be reasonably estimated due to significant uncertainties in the timing and manner of settlement of those obligations. Asset retirement obligations that are reasonably estimable as of September 30, 2017,March 31, 2018, are immaterial to our consolidated financial condition, results of operations and cash flows.

Note 5 — Earnings per Share and Unit
Aimco and the Aimco Operating Partnership calculate basic earnings per common share and basic earnings per common unit based on the weighted average number of shares of Common Stock and common partnership units and participating securities outstanding, and calculate diluted earnings per share and diluted earnings per unit taking into consideration dilutive common stock and common partnership unit equivalents and dilutive convertible securities outstanding during the period.
Our common stock and common partnership unit equivalents include options to purchase shares of Common Stock, which, if exercised, would result in Aimco’s issuance of additional shares and the Aimco Operating Partnership’s issuance to Aimco of additional common partnership units equal to the number of shares purchased under the options. These equivalents also include unvested total shareholder return-basedstockholder return, or TSR, restricted stock and unit awards that do not meet the definition of participating securities, which would result in an increase in the number of common shares and common partnership units outstanding equal to the number of shares that vest. The effect of 0.1 million and 0.5 million of these securities was dilutive for the three and nine months ended September 30,March 31, 2018 and 2017, respectively, and 2016, and accordingly has beenis included in the denominator for calculating diluted earnings per share and unit during these periods. For the three months ended March 31, 2018, 0.2 million potential shares and 0.3 million potential units were not dilutive and have been excluded from the denominator for calculating dilutive earnings per share and per unit, respectively, for the period.
Our time-based restricted stock awards receive dividends similar to shares of Common Stock and common partnership units prior to vesting and our TSR long-term incentive partnership units receive a percentage of the distributions paid to common partnership units prior to vesting. These dividends and distributions are not forfeited inif the event that the restricted stock does notawards fail to vest. Therefore, the unvested shares and units related to these awards are participating securities. The effect of participating securities is included in basic and diluted earnings per share and unit computations using the two-class method of allocating distributed and undistributed earnings.earnings when the two-class method is more dilutive than the treasury method. There were 0.3 million and 0.2 million unvested participating sharessecurities at March 31, 2018 and units at September 30, 2017, and 2016.

respectively.
The Aimco Operating Partnership has various classes of preferred OP Units, which may be redeemed at the holders’ option. The Aimco Operating Partnership may redeem these units for cash, or at its option, shares of Common Stock. As of September 30, 2017,March 31, 2018, these preferred OP Units were potentially redeemable for approximately 2.32.5 million shares of Common Stock (based on the period end market price), or cash. The Aimco Operating Partnership has a redemption policy that requires cash settlement of redemption requests for the preferred OP Units, subject to limited exceptions. Accordingly, we have excluded these securities from earnings per share and unit computations and we expect to exclude them in future periods.
Note 6 — Fair Value Measurements
Recurring Fair Value Measurements
We measure at fair value on a recurring basis our investments in the securitization trust that holds certain of our property debt, which we classify as available for sale or AFS,(or AFS) debt securities, and our interest rate swaps, both of which are classified within Level 2 of the GAAP fair value hierarchy.
Our investments in debt securities classified as AFS are presented within other assets in the accompanying condensed consolidated balance sheets. We hold several positions in the securitization trust that pay interest currently and we also hold the first loss position in the securitization trust, which accrues interest over the term of the investment. We are accreting the discount to the $100.9 million face value of the investments into interest income using the effective interest method over the remaining term of the investments, which, as of September 30, 2017,March 31, 2018, was approximately 3.73.2 years. Our amortized cost basis for these investments, which represents the original cost adjusted for interest accretion less interest payments received, was $76.4$79.1 million and $72.5$77.7 million at September 30, 2017March 31, 2018 and December 31, 2016,2017, respectively. We estimated the fair value of these investments to be $79.9$83.6 million and $76.1$82.8 million at September 30, 2017March 31, 2018 and December 31, 2016,2017, respectively.
We estimate the fair value of these investments using an income and market approach with primarily with observable inputs, including yields and other information regarding similar types of investments, and adjusted for certain unobservable inputs specific to these investments. The fair value of the positions that pay interest currently typically moves in an inverse relationship with movements in interest rates. The fair value of the first loss position is primarily correlated to collateral quality and demand for similar subordinate commercial mortgage-backed securities.
Certain consolidated partnerships served by our Asset Management business have entered into interest rate swap agreements, which limit exposure to interest rate fluctuationsrisk on the partnerships’ variable-rate debt by effectively converting the interest on variable-rate debtfrom a variable rate to a fixed rate. We estimate the fair value of interest rate swaps using an income approach with primarily observable inputs, including information regarding the hedged variable cash flows and forward yield curves relating to the variable interest rates on which the hedged cash flows are based.

The following table sets forth a summary of the changes in fair value of these interest rate swaps (in thousands):

Realized losses on derecognitionAs of March 31, 2018 and December 31, 2017, the interest rate swaps included in earnings represents previously unrealized losses related to an interest rate swap to which the partnership owning the final Napico property was a party. Upon derecognition of the assets and liabilities related to the final property, we also wrote off the accumulated other comprehensive income related to this swap, which was included in the gain on derecognition included in other, net on our condensed consolidated statement of operations for the three and nine months ended September 30, 2017. Please refer to Note 3 for further discussion.
As of September 30, 2017 and December 31, 2016, the remaining interest rate swaps, exclusive of the derecognized Napico interest rate swap, had aggregate notional amounts of $22.1$21.8 million and $22.4$22.0 million, respectively. As of September 30, 2017,March 31, 2018, these swaps had a weighted average remaining term of 6.25.7 years. We have designated these interest rate swaps as cash flow hedges. The fair value of these swaps is presented within accrued liabilities and other (Asset Management) in our condensed consolidated balance sheets, and

we recognize any changes in the fair value as an adjustment of accumulated other comprehensive loss within equity and partners’ capital to the extent of their effectiveness.
If the forward rates at September 30, 2017March 31, 2018, remain constant, we estimate that during the next 12 months, we would reclassify into earnings approximately $0.5$0.4 million of the unrealized losses in accumulated other comprehensive loss into earnings.loss. If market interest rates increase above the 3.26% weighted average fixed rate under these interest rate swaps, the consolidated partnerships will benefit from net cash payments due from the counterpartiescounterparty to the interest rate swaps.
In connection with the anticipated third quarter sale of the Asset Management business, these obligations will be assumed by the purchaser.
Fair Value Disclosures
We believe that the carrying values of the consolidated amounts of cash and cash equivalents, receivables and payables approximatesapproximate their fair valuevalues at September 30, 2017March 31, 2018, and December 31, 2016,2017, due to their relatively short-term nature and high probability of realization. The estimated faircarrying value of the total indebtedness associated with our Real Estate portfolio was approximately $4.2 billion and $3.7 billion at September 30, 2017 and December 31, 2016, respectively, as compared to carrying amounts of $4.2 billion and $3.6 billion, respectively. The carrying values of the non-recourse property debt of the consolidated partnerships served by our Asset Management business approximated its estimated fair value at September 30, 2017March 31, 2018 and December 31, 2016.2017. We estimate the fair value of our consolidated debt using an income and market approach, including comparison of the contractual terms to observable and unobservable inputs such as market interest rate risk spreads, contractual interest rates, remaining periods to maturity, collateral quality and loan to value ratios on similarly encumbered assetsapartment communities within our portfolio. We classify the fair value of debt within Level 3 of the GAAP valuation hierarchy based on the significance of certain of the unobservable inputs used to estimate theirits fair values.value.
Note 7 — Business Segments
In 2017, we revised the information regularly reviewed by ourOur chief executive officer, who is our chief operating decision maker, to assess our operating performance. Apartment communities are classified as either part of our Real Estate portfolio or those owned through partnerships served by our Asset Management business.
Our Real Estate portfolio consisted of 141 apartment communities with 39,184 apartment homes at September 30, 2017. This portfolio is diversified by both price point and geography and consists primarily of market rate apartment communities.
Our chief operating decision maker, uses proportionate property net operating income to assess the operating performance of our apartment communities. Proportionate property net operating income reflectsis defined as our share of rental and other property revenuesrevenue less directour share of property operating expenses, including real estate taxes, for consolidated apartment communities we own and manage. Beginning in 2018, we exclude from rental and other property revenues the amount of utilities cost reimbursed by residents and reflect such amount as a reduction of the related utility expense within property operating expenses in our evaluation of segment results. In our condensed consolidated statements of operations, utility reimbursements are included in rental and other property revenues, in accordance with GAAP. The tables below have been revised to conform to this presentation.
Apartment communities are classified as either part of our Real Estate portfolio or those owned through partnerships served by our Asset Management business. As of September 30, 2017,March 31, 2018, for segment performance evaluation, our Real Estate segment included 137130 consolidated apartment communities with 39,04237,086 apartment homes and excluded four apartment communities with 142 apartment homes that we neither manage nor consolidate.
As discussed in Note 1, as of September 30, 2017,March 31, 2018, through our Asset Management business we also ownedheld nominal ownership positions in consolidated partnerships for which we provide asset management services. These partnershipsthat own 46 low-income housing tax credit apartment communities with 6,898 apartment homes. Neither the results of operations nor the assets of these partnerships and apartment communities are quantitatively material; therefore, we have one reportable segment, Real Estate. The results of operations for the three and nine months ended September 30, 2016, and the segment assets as of December 31, 2016, shown below have been revised to reflect the change in our reportable segments.

The following tables present the revenues, net operating income and income before gain on dispositions of our Real Estate segment on a proportionate basis (excluding amounts related to apartment communities sold)sold as of March 31, 2018) for the three and nine months ended September 30,March 31, 2018 and 2017 and 2016 (in thousands):

Note 8 — Variable Interest Entities
Aimco consolidates the Aimco Operating Partnership, which isGenerally, a variable interest entity, or VIE, for which Aimco is the primary beneficiary. Aimco, through the Aimco Operating Partnership, consolidates all VIEs for which we are the primary beneficiary. Generally, a VIE, is a legal entity in which the equity investors do not have the characteristics of a controlling financial interest or the equity investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support. A limited partnership is considered a VIE when the majority of the limited partners unrelated to the general partner possess neither the right to remove the general partner without cause, nor certain rights to participate in the decisions that most significantly affect the financial results of the partnership. In determining whether we are the primary beneficiary of a VIE, we consider qualitative and quantitative factors, including, but not limited to: which activities most significantly impact the VIE’s economic performance and which party controls such activities; the amount and characteristics of our investment; the obligation or likelihood for us or other investors to provide financial support; and the similarity with and significance to our business activities and the business activities of the other investors. Significant judgments related to these determinations include estimates about the current and future fair values and performance of real estate held by these VIEs and general market conditions.
Aimco consolidates the Aimco Operating Partnership, which is a VIE for which Aimco is the primary beneficiary. Aimco, through the Aimco Operating Partnership, consolidates all VIEs for which the Aimco Operating Partnership is the primary beneficiary.
All of the VIEs we consolidate own interests in one or more apartment communities. VIEs that own apartment communities we classify as part of our Real Estate segment are typically structured to generate a return for their partners through the operation and ultimate sale of the communities. We are the primary beneficiary in the limited partnerships in which we are the sole decision maker and have a substantial economic interest.
All of theCertain partnerships served by our Asset Management business own interests in low-income housing tax credit apartment communities that are structured to provide for the pass-through of tax credits and tax deductions to their partners and are VIEs. We hold a nominal ownership position in these partnerships, generally one percent or less. As general partner in these partnerships, we are the sole decision maker and we receive fees and other payments in return for the asset management and other services we provide and thus share in the economics of the partnerships, and as such, we are the primary beneficiary of these partnerships. The table below summarizes information regarding VIEs consolidated by the Aimco Operating Partnership:

Forward Looking Statements
The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking statements in certain circumstances. Certain information included in this Quarterly Report contains or may contain information that is forward-looking, within the meaning of the federal securities laws, including, without limitation, statements regarding: our ability to maintain current or meet projected occupancy, rental rate and property operating results; the effect of acquisitions, dispositions, redevelopments and developments; our ability to meet budgeted costs and timelines, and achieve budgeted rental rates related to our redevelopment and development investments; expectations regarding sales of our apartment communities and the use of proceeds thereof; and our ability to comply with debt covenants, including financial coverage ratios.
Actual results may differ materially from those described in these forward-looking statements and, in addition, will be affected by a variety of risks and factors, some of which are beyond our control, including, without limitation:
Real estate and operating risks, including fluctuations in real estate values and the general economic climate in the markets in which we operate and competition for residents in such markets; national and local economic conditions, including the pace of job growth and the level of unemployment; the amount, location and quality of competitive new housing supply; the timing of acquisitions, dispositions, redevelopments and developments; and changes in operating costs, including energy costs;
Financing risks, including the availability and cost of capital markets financing andmarkets’ financing; the risk that our cash flows from operations may be insufficient to meet required payments of principal and interestinterest; and the risk that our earnings may not be sufficient to maintain compliance with debt covenants;
Insurance risks, including the cost of insurance, and natural disasters and severe weather such as hurricanes; and
Legal and regulatory risks, including costs associated with prosecuting or defending claims and any adverse outcomes; the terms of governmental regulations that affect us and interpretations of those regulations; and possible environmental liabilities, including costs, fines or penalties that may be incurred due to necessary remediation of contamination of apartment communities presently or previously owned by us.
In addition, our current and continuing qualification as a real estate investment trust involves the application of highly technical and complex provisions of the Internal Revenue Code and depends on our ability to meet the various requirements imposed by the Internal Revenue Code, through actual operating results, distribution levels and diversity of stock ownership.
Readers should carefully review our financial statements and the notes thereto, as well as the section entitled “Risk Factors” described in Item 1A of Apartment Investment and Management Company’s and AIMCO Properties, L.P.’s combined Annual Report on Form 10-K for the year ended December 31, 2016,2017, and the other documents we file from time to time with the Securities and Exchange Commission.

Executive Overview
Aimco and the Aimco Operating Partnership
We are focused on the ownership, management, redevelopment and limited development of quality apartment communities located in some of the largest markets in the United States. Our business activities are defined by a commitment to our core values of integrity, respect, collaboration, performance and a focus on our customers. These values and our corporate mission, “to consistently provide quality apartment homes in a respectful environment delivered by a team of people who care,” shape our culture. In all our interactions with residents, team members, business partners, lenders and equity holders, we aim to be the best owner and operator of apartment communities and an outstanding corporate citizen.
Our principal financial objective is to provide predictable and attractive returns to our equity holders. We measure our total return using growth in Economic Income and our current return using Adjusted Funds From Operations, (eachor AFFO, and our long-term total return using Economic Income. We also use Pro forma Funds From Operations, or Pro forma FFO, as a measure of which are defined under the Non-GAAP Measures heading below).operational performance. Our business plan to achieve this principal financial objective is to:
operate our portfolio of desirable apartment homes with valued amenities, with a high level of focus on customer selection and customer satisfaction and in an efficient manner that realizes the benefits of our corporate systemsproduces predictable and local management expertise;growing Free Cash Flow;

improve our portfolio of apartment communities, which is diversified both by geography and price point and which averages “B/B+” in quality (defined under the Portfolio Management heading below) by selling apartment communities with lower projected free cash flow returnsFree Cash Flow internal rates of return and investing the proceeds from such sales in prospects with higher projected free cash flow returns than expected from the communities sold, such as property upgrades,through capital enhancements, redevelopment, development, and selective acquisitions;
acquisitions with greater land value, higher expected rent growth, and projected Free Cash Flow internal rates of return in excess of those expected from communities sold;
use low levels of financial leverage, primarily in the form of non-recourse, long-dated, fixed-rate property debt and perpetual preferred equity, a combination which reduces our refunding and re-pricing risk and which provides a hedge against increases in interest rates; and
emphasizefocus intentionally on a collaborative respectful, and performance-orientedproductive culture with high team engagement.based on respect for others and personal responsibility.
Our business is organized around our strategic five areas of strategic focus: property operations; redevelopment/development;operational excellence; redevelopment; portfolio management; balance sheet; and team and culture.
The results from the execution of our business plan during the three months ended September 30, 2017,March 31, 2018, are further described below.
Net income attributable to common stockholders per common share increased by $0.04$0.45 in the three months ended September 30, 2017,March 31, 2018, as compared to the same period in 2016, primarily2017, due to increased contributionhigher gains on sale of apartment communities and a higher tax benefit resulting from property net operating income more fully described below, partially offset by higher depreciation expense.an intercompany transfer of assets related to the Asset Management business.

Property Operations
We own and operate a portfolio of market rate apartment communities, diversified by both geography and price point.point, which we refer to as our Real Estate portfolio. At September 30, 2017,March 31, 2018, our Real Estate portfolio included 141 predominantly market rate included 134 apartment communities with 39,18437,228 apartment homes in which we held an average ownership of approximately 99%. This portfolio was divided about two thirds by value to our “Same Store” portfolio of stabilized apartment communities and about one third by value to “Other Real Estate,” which includes recently acquired communities and communities under redevelopment or development whose long-term financial contribution is not yet stabilized.
Our property operations team delivered solid results for our Real Estate portfolio for the three months ended September 30, 2017.March 31, 2018. Highlights for the quarter include:
Same Store net operating income increased year-over-year by 4.5%, consisting of revenue growth of 2.8% and expense reduction of 1.1%; and2.7% for the three months ended March 31, 2018 compared to 2017;
Same Store rent increases on renewals and new leases averaged 4.5%4.9% and 1.4%0.4%, respectively, for a weighted average increase of 3.0%2.7%; and
Average daily occupancy of .96.3%, 30 basis points higher than the same period in 2017.

Redevelopment/DevelopmentRedevelopment
Redevelopment/Development is ourOur second line of business. Within our Real Estate portfolio, we invest inbusiness is the redevelopment of apartment communities, whenwhere we believe the investment will yield risk-adjusted returns in excess of those expected from the apartment communities sold in paired trades to fund the redevelopment.
We have undertaken a range of redevelopments, including those in which buildings or exteriors are renovated without the need to vacate apartment homes; those in which significant renovation of apartment homes may be accomplished upon lease expiration and turnover; and those in which an entire building or community is vacated. We execute our redevelopments using a phased approach, in which we renovate portions of an apartment community in stages. Redevelopment work may include seeking entitlements from local governments, which enhance the value of our existing portfolio by increasing density, that is, the right to add apartment homes to a site. We expect to create value equal to 25% to 35% of our incremental investment in redevelopment.
by repositioning communities within our portfolio. We favor redevelopment because it permits adjustmentmeasure the rate and quality of the scope and timingfinancial returns by net asset value creation, an important component of spending to align with changing market conditions.
Economic Income, our primary measure of long-term financial performance. We also undertake ground-up development when warranted by risk-adjusted investment returns, either directly in connection with the redevelopment of an existing apartment community or, on a more limited basis, at a new location. In such cases,When

DuringWe invest to earn risk-adjusted returns in excess of those expected from the three months ended September 30, 2017,apartment communities sold in paired trades to fund the redevelopment or development. Of these two activities, we invested $33.3 million primarily in our ongoing redevelopmentsfavor redevelopment because it permits adjustment of the scope and continuedtiming of spending to lease redeveloped apartment homes at a pace consistentalign with our expectations.changing market conditions and customer preferences.
During the three months ended September 30, 2017,March 31, 2018, we completed construction on the third tower of Park Towne Placeinvested $46.8 million in redevelopment and development. In Center City, Philadelphia. As of September 30, 2017, this tower was 74% leased at rates consistent with underwriting. We expect this tower to be more than 90% leased by year-end, as are the first two towers redeveloped at the community.
In the past three years,Philadelphia, we have leased more than 1,100 redeveloped apartment homes in Center City, Philadelphia. Basedcontinued construction on these results, we decided to proceed with a $40.0 million redevelopment of the fourth and final tower atof Park Towne Place. De-leasingInitial move-ins have occurred and at the end of April, 31% of the tower was pre-leased.
Construction is underway, on plan and construction is scheduled to commence by year end.
In 2014, we acquired Eastpointe, a “C” property located in Boulder, Colorado. The site is two miles from the new Google campus and is across the street from Ball Aerospace’s Technology Campus and Foothills Hospital. Building in Boulder is highly regulated and new supply is limited, notwithstanding higher enrollmenton budget at the University of Colorado and increased employment generally. Over the past two years, we have planned and entitled a newParc Mosaic, our $117.0 million, 226 apartment home community to be known as Parc Mosaic. De-leasingbeing developed on the site of our former Eastpointe is now underway and construction ofcommunity in Boulder, Colorado. We expect Parc Mosaic is scheduled to commence by year end.will be available for occupancy in the summer of 2019.
Inclusive of these two new projects, ourOur total estimated net investment in redevelopment/developmentour current redevelopments and developments is $710.4$432.8 million with a projected weighted average net operating income yield on these investments of 6.1%, assuming untrended rents. Of this total, $481.4$279.0 million has been funded. 2018 funding needs for our remaining redevelopment and development investment will be satisfied with proceeds from our planned sale of the Asset Management business and Hunters Point communities, discussed below.
During the three months ended September 30, 2017,March 31, 2018, we leased 27859 apartment homes at our redevelopment and acquisition communities.
In measuring lease-up exposure related to redevelopment activities, we consider: (a) apartments that have been de-leased in preparation for construction; (b) apartments currently under construction; and (c) apartments for which construction is complete and the apartment home is ready for occupancy. In each case, lease-up exposure is measured as the number of homes to be leased for the apartment community to achieve 95% occupancy.
As of September 30, 2017,March 31, 2018, our exposure to lease-up exposure at active redevelopment and development projects includedwas approximately 360527 apartment homes. Of these, 231 related to apartments that have been or will be de-leased for redevelopmenthomes, of which 201 were in the finalfourth tower atof Park Towne Place 33 related to apartment homes under construction, and 103 related to homes for which construction is complete and the homes are available for occupancy.215 were being constructed at Parc Mosaic.

Portfolio Management
Our portfolio strategy seeks predictable rent growth from a portfolio of apartment communities that is diversified across “A,” “B”“B,” and “C+” price points, averaging “B/B+” in quality, and that is also diversified across some of the largest markets in the United States.

U.S. We measure the quality of apartment communities in our Real Estate portfolio based on average rents of our apartment homes compared to local market average rents as reported by a third-party provider of commercial real estate performance and analysis. Under this rating system, we classify as “A” quality apartment communities those earning rents greater than 125% of the local market average,average; as “B” quality apartment communities those earning rents between 90% and 125% of the local market average; as “C+” quality apartment communities are those earning rents greater than $1,100 per month, but lower than 90% of the local market average; and as “C” quality apartment communities are those earning rents less than $1,100 per month and lower than 90% of the local market average. We classify as “B/B+” quality a portfolio that on average earns rents between 100% and 125% of the local market average rents where the portfolio is located. Although some companies and analysts within the multifamily real estate industry use apartment community quality ratings of “A,” “B” and “C,” some of which are tied to the local market rent averages, the metrics used to classify apartment community quality as well as the timingperiod for which the local market rents are calculated may vary from company to company. Accordingly, our rating system for measuring apartment community quality is neither broadly nor consistently used in the multifamily real estate industry.
As part of our portfolio strategy, we seek to sell each year up to 10% of the apartment communities in our portfolio annually and to reinvest the proceeds from such sales in accretive uses such as property upgrades, redevelopment of communities in its current portfolio,capital enhancements, redevelopments, occasional development, of new communities, and selective acquisitions with projected Free Cash Flow internal rates of apartment communities withreturn higher projected free cash flow returns than expected from the communities sold to fund the activity.being sold. Through this disciplined approach to capital recycling, we have significantly increased the quality and expected growth rate of itsour portfolio.

This increase is due to year-over-year growth in Same Store revenue as well as our second quarter 2017 reacquisition of the 47% limited partnership interest in the Palazzo joint venture,communities, lease-up of redevelopment and acquisition apartment communities,properties, and the sale of apartment communities with average monthly revenues per Aimco apartment home lower than those of the retained portfolio.

Balance Sheet and LiquidityApartment Community Acquisitions
We targetevaluate potential acquisitions with an eye for unique and opportunistic investments and fund acquisitions pursuant to our strict paired trade discipline.
During the three months ended March 31, 2018, we purchased for $160.0 million Bent Tree Apartments, a 748-apartment home community in Fairfax County, Virginia. Bent Tree is a “B” quality community located in a market we know well from our ownership of two nearby communities built by the same developer. Further, we believe the same business plan used at these communities will produce greater than market rate net leverageoperating income growth for Bent Tree. The community is expected to achieve a 5.6% year one net operating income capitalization rate. Before consideration of $3.8 billion. Our leverage is currently above this targetcapital enhancement opportunities, new lease rents are 4% higher than expiring leases, as compared to new lease rents that have decreased elsewhere in northern Virginia. We funded the secondacquisition with bank borrowings pending the expected third quarter reacquisitionsale of the 47% limited partner interest in the Palazzo joint venture was temporarily funded with debt. We are on track with plansour Asset Management business, described below.
Subsequent to sellMarch 31, 2018, we entered into a transaction to acquire six apartment communities in the Philadelphia area for a stated purchase price of $445.0 million. The portfolio includes 1,006 existing apartment homes, 110 apartment homes under construction, and 185,000 square feet of office and retail space. This “A” quality portfolio is located primarily in the Center City and University City submarkets of Philadelphia. We anticipate that our operation of the five operating communities will generate a year one net operating income yield of 5.3%, and for all six communities, average revenue per apartment home of $2,200 and a ten-year expected free cash flow internal rate of return of about 8%.
The $445.0 million acquisition will be funded initially through taking title subject to $290.0 million of non-recourse property debt, issuance of $90.0 million in common OP Units valued in the transaction at their estimated net asset value per unit (approximately 1.7 million common OP Units), and payment of $65.0 million in cash funded from bank borrowings. The ultimate paired trade funding includes the sale of Chestnut Hill Village, located in north Philadelphia, and the sale of the Asset Management business, described below.
On May 1, 2018, we completed the acquisition of four of the six apartments communities including 665 apartment homes and 153,000 square feet of office and retail space. We anticipate the acquisition of the fifth apartment community during the summer of 2018 and the acquisition of the final apartment community upon completion of construction, expected in the first half of 2019.
Apartment Community Dispositions
During the three months ended March 31, 2018, we sold three apartment communities with 513 apartment homes for a gain of $50.6 million, net of income tax, and gross proceeds of $71.9 million resulting in $64.6 million in net proceeds to us. Two of these communities are located in southern Virginia Maryland, and New Jerseyone is located in suburban Maryland. Proceeds from these sales were used to repay outstanding borrowings on our revolving credit facility, effectively funding the equity portion of the Palazzo reacquisition as well as our 2017 redevelopment and development activities.
During the three months ended March 31, 2018, we sold our interests in the entities owning the La Jolla Cove property in settlement of legal actions filed in 2014 by a group of disappointed buyers who had hoped to acquire the property. We provided seller financing with a stated value of $48.6 million and received net cash proceeds of approximately $5.0 million in the sale.
In April 2018, we entered into a binding agreement to sell for $590.0 million our Asset Management business and the four Hunters Point affordable communities. We expect to close this transaction during the third quarter of 2018. After payment of closing costs and repayment of property level debt encumbering the Hunters Point apartment communities, net proceeds are expected to be approximately $512.0 million, which we plan to use to: repay the borrowings on our credit facility used to fund our acquisition of Bent Tree Apartments and the acquisition of the apartment communities in the Philadelphia portfolio; reduce our overall leverage; fund 2018 redevelopment; and redeem Aimco’s Class A Cumulative Preferred Stock, which is callable in second quarter 2019. Taken together, these transactions are expected to reduce leverage to our $3.8 billion target.AFFO by $0.03 per share and $0.04 per share in 2018 and 2019, respectively, before becoming accretive in 2021.

Balance Sheet
Our leverage includes our share of long-term, non-recourse property debt secured byencumbering apartment communities in our Real Estate portfolio, our one-year term loan, outstanding borrowings under our revolving credit facility, and outstanding preferred equity. In our calculation of leverage, we exclude non-recourse property debt obligations of consolidated partnerships served by our Asset Management business, as these are not our obligations and they have limited effect on the amount of fees and other amounts we expect to receive in our role as asset manager for these partnerships.
Our leverage strategy seeks to increase financial returns while using leverage with appropriate caution. We limit risk through balance sheet structure, employing low leverage, primarily non-recourse and long-dated property debt; build financial flexibility by maintaining ample unused and available credit as well as holding properties with substantial value unencumbered by property debt; and use partners’ capital when it enhances financial returns or reduces investment risk.
We target the ratio of Proportionate Debt and Preferred Equity to Adjusted EBITDA to be below 7.0x and we target the ratio of Adjusted EBITDA to Adjusted Interest Expense and Preferred Dividends to be greater than 2.5x. We also focus on the ratios of Proportionate Debt to Adjusted EBITDA and Adjusted EBITDA to Adjusted Interest Expense.
Proportionate Debt, Adjusted EBITDA and Adjusted Interest Expense, as used in these ratios, are non-GAAP financial measures, which are further discussed and reconciled under the Non-GAAP Measures Leverage Ratios heading. Preferred Equity represents

Aimco’s preferred stock and the Aimco Operating Partnership’s preferred OP Units. Our leverage ratios for the three months ended September 30, 2017March 31, 2018, are presented below:
Three Months Ended September 30, 2017
Proportionate Debt to Adjusted EBITDA6.9x 6.8x
Proportionate Debt and Preferred Equity to Adjusted EBITDA7.3x 7.2x
Adjusted EBITDA to Adjusted Interest Expense3.4x 3.6x
Adjusted EBITDA to Adjusted Interest Expense and Preferred Dividends3.1x 3.2x
We calculate Adjusted EBITDA and Adjusted Interest Expense used in our leverage ratios based on the most recent three month amounts, annualized. We expectOur leverage ratios have been calculated on a pro forma basis to reflect the acquisition of Bent Tree Apartments and the disposition of three apartment communities during the period as if the transactions had closed on January 1, 2018. As used in the ratios above, Preferred Equity represents Aimco’s preferred stock and the Aimco Operating Partnership’s preferred OP Units.
Future improvement in leverage metrics is expected from earnings growth, primarily due to increasing contributionthe repayment of bank borrowings and property level debt with the proceeds from redevelopment apartment communitiesour expected third quarter sale of the Asset Management business and reduction in debt balances due to regularly scheduled debt amortization and apartment community sales, partially offset by the loss of earnings from soldHunters Point communities. We also expect that these activities will reduceto use the proceeds from this sale to redeem Aimco’s Class A Cumulative Preferred Stock, which is callable in second quarter 2019. We expect our Proportionate Debt to Adjusted EBITDA and Proportionate Debt and Preferred Equity to Adjusted EBITDA ratios to decrease by year-endthe end of 2018 to approximately 6.2x6.3x and 6.6x,6.7x, respectively.
During the three months ended September 30, 2017,March 31, 2018, we closed or rate locked fivetwo non-recourse, fixed-rate property loans totaling $297.3$242.0 million. OnThese loans have 10-year terms and a weighted average basis, these loans have a 9.6 year term and an interest rate of 3.43%3.48%, 125126 basis points more thanabove the corresponding Treasurytreasury rates at the time of pricing.
The net effect of 20172018 fixed-rate property debt refinancing activities has been to lower our weighted average fixed interest ratesrate by aboutnearly 10 basis points since December 31, 2017, to 4.75%4.55%, generatingreducing prospective annual interest savings of approximatelyexpense by more than $3.0 million.
We also closed two non-recourse, variable-rate property loans totaling $118.6 million. These loans each have a five-year term and bear interest at 30-day LIBOR plus 1.25%. The five-year terms fill a hole in our laddered maturities and, taken together with the planned repayment of the variable term loan, reduce our exposure to increasing short-term interest rates to less than 7% of our leverage.
Our liquidity consists of cash balances and available capacity on our revolving line of credit. As of September 30, 2017,March 31, 2018, we had on hand $600.0 million in cash and restricted cash plus available capacity on our revolving line of credit.
We also manage our financial flexibility by maintaining an investment grade rating and holding apartment communities that are unencumbered by property debt. At March 31, 2018, we held unencumbered apartment communities with an estimated fair value of approximately $1.8 billion, an increase of approximately12% from December 31, 2016.$2.0 billion.
Two credit rating agencies rate our creditworthiness using different methodologies and ratios for assessing our credit, and both have rated our credit and outlook as BBB- (stable), an investment grade rating. Although some of the ratios they use are similar to those we use to measure our leverage, there are differences in our methods of calculation and therefore our leverage ratios disclosed above may not be indicative of the ratios that may be calculated by these agencies.
For additional information regarding our leverage, please see the discussion under the Liquidity and Capital Resources heading.

Team and Culture
Our team and culture is the keyare keys to our success. Our emphasisintentional focus on a collaborative respectful, and performance-orientedproductive culture based on respect for others and personal responsibility is what enablesreinforced by a preference for promotion from within. We focus on succession planning and talent development to produce a strong, stable team that is the continuing transformationenduring foundation of the Aimco business.our success. In April 2017, Aimco was2018, we were recognized by the Denver Post as a Top Work Place. We are one ofPlace for the sixth consecutive year, an accomplishment shared with only a dozen Coloradoseven other companies of all sizes who have earned this designation for five consecutive years.in Colorado.
Key Financial Indicators
The key financial indicators that we use in managing our business and in evaluating our operating performance are Economic Income, our measure of long-term total return, and Adjusted Funds From Operations, our measure of current return. In addition to these indicators, we evaluate our operating performance and financial condition using: Pro forma Funds From Operations;FFO; Free Cash Flow, or FCF, capitalization rate; net operating income, or NOI, capitalization rate;FCF; same store property net operating results;income; proportionate property net operating income; average revenue per Aimcoeffective apartment home; financial coverageleverage ratios; and net leverage. Certain of these financial indicators are non-GAAP financial measures, which are defined, further described, and for certain of the measures, reconciled to comparable GAAP-based measures, under the Non-GAAP Measures heading.
Results of Operations
Because our operating results depend primarily on income from our apartment communities, the supply of and demand for apartments influences our operating results. Additionally, the level of expenses required to operate and maintain our apartment communities and the pace and price at which we redevelop, acquire and dispose of our apartment communities affect our operating results.
The following discussion and analysis of the results of our operations and financial condition should be read in conjunction with the accompanying condensed consolidated financial statements in Item 1.

Three and Nine Months Ended September 30, 2017March 31, 2018 compared to September 30, 2016March 31, 2017
Net income attributable to Aimco increased by $4.1 million and decreased by $214.6$70.1 million during the three and nine months ended September 30, 2017, respectively,March 31, 2018 as compared to the September 30, 2016 comparable periods.2017. Net income attributable to the Aimco Operating Partnership increased by $4.8 million and decreased by $224.4$73.3 million during the three and nine months ended September 30, 2017, respectively,March 31, 2018 as compared to the September 30, 2016 comparable periods.2017. The increase in income for Aimco and the Aimco Operating Partnership for the three months ended was due primarily to a variety of factors, including improved operating results. The decrease in income for Aimco and$50.3 million gain on the Aimco Operating Partnership for the nine months ended was primarily due to lower gains on disposition of real estate.estate and a $32.4 million increase in tax benefit resulting from an intercompany transfer of assets related to the Asset Management business.
The following paragraphs discuss these and other items affecting the results of operations of Aimco and the Aimco Operating Partnership in more detail.
Property Operations
As described under the preceding Executive Overview heading, our Real Estate segment consists primarily of market rate apartment communities in which we hold a substantial equity ownership interest.
We use proportionate property net operating income to assess the operating performance of our apartment communities.Real Estate Portfolio. Proportionate property net operating income reflects our share of rental and other property revenues less direct property operating expenses, including real estate taxes, for consolidated apartment communities we manage. Accordingly, the results of operations of our Real Estate segment discussed below are presented on a proportionate basis and exclude the results of four apartment communities with 142 apartment homes that we neither manage nor consolidate.
Additionally, we evaluate the revenue and expense performance of our segment as adjusted for utility reimbursements. Nearly two-thirds of our utility costs are reimbursed by residents. These reimbursements are included in rental and other property revenues in our condensed consolidated statements of operations prepared in accordance with GAAP, but beginning in 2018, our segment results below reflect utility reimbursements as a reduction of the corresponding expense.
We do not include property management revenues, offsite costs associated with property management or casualty-related amounts in our assessment of segment performance. Accordingly, these items are not allocated to our segment results discussed below.
Refer to Note 7 ofin the condensed consolidated financial statements in Item 1 for further discussion regarding our reportable segment,segments, including a reconciliation of these proportionate amounts to the corresponding amounts in our condensed consolidated statements of operations.

Real Estate Proportionate Property Net Operating Income
We classify apartment communities within our Real Estate segment as Same Store and those Outside ofOther Real Estate. Same Store. Same Store apartment communities are those that have reached a stabilized level of operations as of January 1, 2016the beginning of a two-year comparable period and maintained it throughout the current and comparable prior periods, and are not expected to be sold within 12 months.

For the three months ended September 30, 2017, asMarch 31, 2018 compared to the three months ended September 30, 2016,2017, our Real Estate segment’s proportionate property net operating income increased $16.8$11.6 million, or 11.9%8.2%.
Same Store proportionate property net operating income increased by $4.6$2.8 million, or 4.5%2.7%. This increase was primarily attributable to a $4.1$3.6 million, or 2.8%2.6%, increase in rental and other property revenues due to higher average monthly revenues (approximately $50($42 per Aimco apartment home), comprised primarily of increases in rental rates and a 20 basis point increase in average daily occupancy. Rental rates on renewals transacted duringrates.

For the nine months ended September 30, 2017, as compared to the nine months ended September 30, 2016, our Real Estate segment’s proportionate property net operating income increased $39.7 million, or 9.5%
Same Store proportionate property net operating income increased by $13.6 million, or 4.6%. This increase was primarily attributable to a $14.0 million, or 3.3%, increase in rental and other property revenues due to higher average revenues (approximately $62 per effective home), comprised primarily of increases in rental rates, partially offset by a 10 basis point decrease in average daily occupancy. Rental rates on renewals transacted during the nine months ended September 30, 2017 were 4.6% higher than expiring lease rates, and new lease rates were 0.9% higher than expiring lease rates, resulting in a weighted average increase of 2.7%. The increase in Same Store rental and other property revenues was partially offset by a $0.4 million, or 0.3%, increase in property operating expenses, primarily due to increases in real estate taxes, utility costs and repairs and maintenance, partially offset by lower personnel and insurance expenses. During the nine months ended September 30, 2017, as compared to 2016, controllable operating expenses, which exclude utility costs, real estate taxes and insurance, decreased by $0.8 million, or 1.3%.
The proportionate property net operating income of our communities Outside of Same Store increased by $26.1 million, or 22.0%, due to:
our completion of the lease-up of Indigo and One Canal earlier in 2017, which contributed to $15.2 million of incremental property net operating income compared to the same period in 2016;
redevelopment leasing activities during the last 12 months, which included 930 apartment homes and helped contribute to incremental redevelopment related property net operating income of $3.2 million during the nine months ended September 30, 2017 as compared to the same period in 2016; and
higher property net operating income of $7.7 million from other communities Outside of Same Store, including the effect of our increased ownership interest in the Palazzo communities as described above.
Non-Segment Real Estate Operations
Operating income amounts not attributed to our Real Estate segment include offsite costs associated with property management, casualty losses, and the results of apartment communities sold, reported in consolidated amounts, which we do not allocate to our Real Estate segment for purposes of evaluating segment performance (see Note 7 to the condensed consolidated financial statements in Item 1).
For the three months ended September 30, 2017,March 31, 2018, casualty losses totaled $2.8$1.1 million and included several large claims primarily related to hurricane damage.water and winter storm damage, partially offset by recovery from insurance carriers for insured losses in excess of policy limits. For the three months ended September 30, 2016,March 31, 2017, casualty losses totaled $2.9$1.9 million and included oneseveral large claimclaims primarily related to fire damage and two large claims related to water damage resulting from damaged pipes.heavy rains in California.
ForNet operating income decreased for the ninethree months ended September 30, 2017, casualty losses totaled $7.1 million asMarch 31, 2018 compared to $5.62017, by $6.5 million for the nine months ended September 30, 2016. The increase was primarily due to casualty losses from Hurricane Irma.
Apartmentapartment communities previously in our Real Estate portfolio that were sold by Decemberas of March 31, 2016, generated net operating income of $3.5 million and $16.9 million, during the three and nine months ended September 30, 2016, respectively.2018.

Asset Management Results
We hold a nominal ownership position in certain consolidated partnerships that own apartment communities that qualify for low-income housing tax credits and are structured to provide for the pass-through of tax credits and tax deductions to their partners. In this role, we provide asset management and other services to these partnerships and receive fees and other payments in return.
In accordance with GAAP, we consolidate most of these partnerships and their underlying apartment communities. Our share of the partnerships’ net operating income, less interest expense and other amounts, was approximately 95% (inclusive of unconsolidated communities) at September 30, 2017, and represents income generated by the partnerships that is currently available to pay fees and other amounts due to us under the contractual agreements.
The operating results of the partnerships served by our Asset Management business and their underlying apartment communities were comparable for the three and nine months ended September 30, 2017, as compared to the three and nine months ended September 30, 2016.
We are also generally responsible for ensuring the underlying apartment communities comply with the requirements to earn low-income housing tax credits. We recognize income associated with the delivery of tax credits and tax deductions delivered to the partners.
For the three and nine months ended September 30, 2017, as compared to the three and nine months ended September 30, 2016, tax credit and transaction revenues decreased by $2.1 million and $9.7 million, respectively. We recognized lower tax credit income, the majority of which was due to our 2016 acquisition of an investor limited partner’s interest in one of the tax credit partnerships (and their rights to undelivered tax credits) prior to the end of the tax credit delivery period. Following the purchase, we generate tax benefits in our results of operations, which largely offsets the tax credit income we otherwise would have recognized. The remainder of the decrease in tax credit income is due to the delivery of the final tax credits for various apartment communities during 2016. Transaction revenues decreased due to a $3.6 million fee earned during the nine months ended September 30, 2016 for assisting a third party property owner with respect to a property we previously owned.
We expect the contribution to our net income from asset management activities to decline in future years as we continue to deliver the final tax credits for these communities and, as part of our plan to exit the Asset Management business, the partnerships sell the underlying apartment communities.
Depreciation and Amortization
For the three and nine months ended September 30, 2017,March 31, 2018 compared to the three and nine months ended September 30, 2016,2017, depreciation and amortization increased $7.7$5.4 million, or 9.0%6.2%, and $23.5 million, or 9.6%, respectively, primarily due to amountsrenovated apartment homes placed in service after thetheir completion, of apartment homes in our Park Towne Place and The Sterling redevelopments, the completion of our One Canal development, our acquisition of Indigo and other capital additions, partially offset by decreases associated with apartment communities sold.
General and Administrative Expenses
For the three and nine months ended September 30, 2017, compared to the three and nine months ended September 30, 2016, general and administrative expenses decreased $1.1 million, or 9.3%, and $3.9 million, or 11.1%, respectively, primarily due to lower compensation costs, professional services and corporate offsite costs.
Other Expenses, net
Other expenses, net includes franchise taxes, costs associated with our risk management activities, partnership administration expenses and certain non-recurring items.
For the three months ended September 30, 2017, compared to the three months ended September 30, 2016, other expenses increased by $0.8 million, primarily due to higher legal costs.
For the nine months ended September 30, 2017, as compared to the nine months ended September 30, 2016, other expenses decreased by $1.8 million, primarily due to the 2016 recognition of estimated environmental clean-up and abatement costs associated with a matter further discussed in Note 4 to the condensed consolidated financial statements in Item 1, partially offset by higher legal costs.

Interest Expense
For the three months ended September 30, 2017, asMarch 31, 2018 compared to the three months ended September 30, 2016,2017, interest expense, which includes the amortization of debt issuance costs, increaseddecreased by $1.3$0.1 million, or 2.6%. The increase was primarily due to higher amounts outstanding on corporate borrowings (including our term loan and incremental line borrowings used to fund the reacquisition of the Palazzo limited partner interests), partially offset by lower average outstanding balances on non-recourse property debt for our Real Estate apartment communities, due to principal amortization and balance repayments and refinancing property loans at lower rates.
For the nine months ended September 30, 2017, as compared to the nine months ended September 30, 2016, interest expense decreased $0.5 million, or 0.3%0.2%. The decrease was primarily due to lower average outstanding balances on non-recourse property debt for our Real Estate apartment communities, due toresulting from principal amortization, balanceprincipal repayments and refinancing property loans at lower rates, partiallylargely offset by loans placed later in 2016 on acquired apartment communities, higher amounts outstanding on corporate borrowings (as described above) and a decrease in capitalized interest associated with our redevelopment and development activities.
Other, net
Other, net includes our equity inused to fund the income or loss2018 acquisition of unconsolidated real estate partnerships, and the results of operations related to the Napico business, which we accounted for under the profit sharing method until September 2017.
For the three and nine months ended September 30, 2017, as compared to the three and nine months ended September 30, 2016, net income of the Napico business increased by $7.1 million and $2.5 million, respectively. As discussed in Note 3 of the condensed consolidated financial statements in Item 1, in September 2017, we derecognized the assets and liabilities related to this property, resulting in a gain.Bent Tree Apartments.
Income Tax Benefit
Certain of our operations, including property management and risk management, are conducted through TRS entities. Additionally, some of our apartment communities are owned through TRS entities.
Our income tax benefit calculated in accordance with GAAP includes: (a) historic tax credits that offset income tax obligations of our TRS entities; (b) income taxes associated with the income or loss of our TRS entities, for which the taxes consequences have been realized in earlier periods or will be realized in future periods; and (c)(b) low income housing tax credits that offset REIT taxable income, primarily from retained capital gains.gains; and (c) historic tax credits that offset income tax obligations of our TRS entities. Income taxes related to these items (before gains on dispositions) are included in income tax benefit in our condensed consolidated statements of operations.
Income tax benefit for the periods presented also reflects GAAP taxes associated with income and gains related to the Napico business, which was deconsolidated at the end of September 2017.
For the three months ended September 30, 2017,March 31, 2018 compared to the three months ended September 30, 2016,2017, income tax benefit increased by $1.4 million. In 2017, we had$32.4 million, primarily due to a tax benefit recognized in connection with an intercompany transfer of assets related to the Asset Management business. This tax benefit is offset slightly by lower historic tax credits associated withgenerated through the redevelopment of certain apartment communities. Notwithstanding these lower historic tax credits, our income tax benefit increased, primarily due to higher operating losses recognized by our TRS entities and higher tax benefits associated with low-income tax credits from our September 2016 acquisition of the limited partner interests in a tax credit partnership. Additionally, in 2017 we recognized higher tax expense than in 2016 due to our derecognition of the final community in the Napico business.
For the nine months ended September 30, 2017, as compared to the nine months ended September 30, 2016, income tax benefit decreased by $1.6 million. Income tax benefit decreased primarily due to lower historic tax credits associated with the redevelopment of certain apartment communities, including the timing of final certification on one redevelopment in 2016. This was partially offset by higher tax benefits associated with low-income tax credits from the 2016 acquisition described above.
Gain on Dispositions of Real Estate, NetInclusive of Related Income Tax
Real Estate
During the three months ended March 31, 2018, we sold three apartment communities with 513 apartment homes for a gain of $50.6 million, net of income tax, and gross proceeds of $71.9 million, resulting in $64.6 million in net proceeds to us. We did not sell any apartment communities from our Real Estate portfolio during the ninethree months ended September 30, 2017, though we sold a commercial property resulting in a small gain. During the nine months ended September 30, 2016, we sold three apartment communities for gross proceeds of $301.9 million, resulting in net proceeds of $299.0 million and net gain on dispositions of real estate of $222.7 million.

March 31, 2017.
Asset Management
Consolidated partnerships served by our Asset Management business did not sell any apartment communities during the three months ended September 30, 2017. During the nine months ended September 30, 2017, consolidated partnerships sold two apartment communities for gross proceeds of $10.9 million, resulting in a gain on disposition of real estate of $2.6 million and related tax expense of $0.9 million.
March 31, 2018. During the three and nine months ended September 30, 2016,March 31, 2017, a consolidated partnership served by our Asset Management business sold an apartment community with 52 apartment homes for a gain of $0.6 million and gross proceeds of $27.5$2.4 million, resulting in $0.4 million in net proceeds of $10.3 million after repayment of property-level debt, payment of transaction costs and distribution of proceeds to noncontrolling interests, and net gain on dispositions of $14.5 million.proceeds.
Noncontrolling Interests in Consolidated Real Estate Partnerships
Noncontrolling interests in consolidated real estate partnerships reflects the results of our consolidated real estate partnerships allocated to the owners who are not affiliated with Aimco. The amounts of income or loss of our consolidated real estate partnerships that we allocate to the owners not affiliated with Aimco include their share of property management fees, interest on notes and other amounts that we charge to these partnerships.
For the three months ended September 30,March 31, 2018 and 2017, and 2016, we allocated net lossincome of $0.2$6.2 million and net income of $12.5$1.0 million, respectively, to noncontrolling interests in consolidated real estate partnerships, representing a decrease of $12.7 million. For the nine months ended September 30, 2017 and 2016, we allocated net income of $1.5 million and $22.1 million, respectively, to noncontrolling interests in consolidated real estate partnerships, representing a decrease of $20.6 million.

The amountsamount of net income allocated to noncontrolling interests related to our Real Estate segmentwas driven by two primary factors: the operations of the consolidated apartment communities and Asset Management business ingains on the aggregate decreased by $11.9 million and $12.5 million during the three and nine months ended September 30, 2017, respectively, primarily due to a decrease in the amountssale of gain we recognized on dispositions of real estate during these periods.apartment communities with noncontrolling interest holders, as further discussed below.
The amountsamount of net income allocated to noncontrolling interests relatedresulting from operations of the consolidated apartment communities was $0.1 million and $1.0 million for the three months ended March 31, 2018 and 2017, respectively. The decrease is primarily due to the Napico business decreased by $0.8 million and $8.1 million during the three and nine months ended September 30, 2017 respectively. As partreacquisition of our ongoing plan to simplify our business, during 2012 we soldlimited partner’s interests in the Napico business. In 2016, we received final payment of the seller financing and we met the requirements to recognizePalazzo joint venture.

In 2017, the current owner of the Napico business refinanced the final property, for which we previously provided a debt guaranty, allowing usapartment communities allocated to derecognize the assets and liabilities related to this property and resulting in a gain.
Net Income Attributable to Aimco Preferred Stockholders and the Aimco Operating Partnership’s Preferred Unitholders
Net income attributable to Aimco Preferred Stockholders decreased by $2.2noncontrolling interests totaled $6.1 million and $3.4 million during the three and nine months ended September 30, 2017, respectively, as compared to the same periods in 2016. Net income attributed to the Aimco Operating Partnership’s Preferred Unitholders decreased by $2.1 million and $2.8 million, respectively, during these periods. The decreases were primarily due to Aimco’s redemption of its Class Z Preferred Stock on July 29, 2016. In connection with the redemption we wrote off previously deferred issuance costs of $1.3 million. Additionally, the $0.7 million excess of redemption value over the carrying amount, was reflected in net income attributable to Aimco Preferred Stockholders and Aimco Operating Partnership’s Preferred Unitholders for the three and nine months ended September 30, 2016.March 31, 2018, and there was no such allocation for the three months ended March 31, 2017.
Critical Accounting Policies and Estimates
We prepare our condensed consolidated financial statements in accordance with GAAP, which requires us to make estimates and assumptions. We believe that the critical accounting policies that involve our more significant judgments and estimates used in the preparation of our condensed consolidated financial statements relate to the impairment of long-lived assets and capitalized costs.
Our critical accounting policies are described in more detail in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, of Aimco’s and the Aimco Operating Partnership’s combined Annual Report on Form 10-K for the year ended December 31, 2016.2017. There have been no significant changes in our critical accounting policies from those reported in our Form 10-K and we believe that the related judgments and assessments have been consistently applied and produce financial information that fairly depicts the results of operations for all periods presented.

Non-GAAP Measures
Various of the key financial indicators we use in managing our business and in evaluating our financial condition and operating performance are non-GAAP measures. Key non-GAAP measures we use are defined and described below, and for those non-

GAAPnon-GAAP measures used or disclosed within this quarterly report, reconciliations of the non-GAAP measures to the most comparable financial measure computed in accordance with GAAP are provided.
Funds fromFrom Operations, or FFO, Pro forma Funds From OperationsFFO and Adjusted Funds From OperationsAFFO are non-GAAP financial measures, which are defined and further described below under the Funds From Operations, Pro Forma Funds From Operations and Adjusted Funds From Operations heading.

Free Cash Flow, or FCF, as calculated for our retained portfolio, represents an apartment community’s property net operating income, or NOI, less spending for capital replacements, which represents our estimation of the capital additions made to replace capital assets consumed during our ownership period (further discussed under the Funds From Operations, Pro Forma Funds From Operations and Adjusted Funds From Operations heading and the Liquidity and Capital Resources headings)heading). FCFFree Cash Flow margin represents an apartment community’s net operating incomeNOI less $1,200 per apartment home of assumed annual capital replacement spending, as a percentage of the apartment community’s rental and other property revenues. Capital replacement spending represents a measure of the cost of capital asset usage during the period; therefore, we believe that FCFFree Cash Flow is useful to investors as a supplemental measure of apartment community performance because it takes into consideration costs incurred during the period to replace capital assets that have been consumed during our ownership.
We use Economic Income as our measure of total return. Economic Income represents stockholder value creation as measured by the change in estimated net asset value per share plus cash dividends per share. We believe Economic Income is important to investors as it represents a measure of the total return we have earned for our stockholders. We report and reconcile our Economic Income annually. Readers should refer to the section entitled “Management’sManagement’s Discussion and Analysis of Financial Condition and Results of Operations”Operations described in Item 7A7 of our Annual Report on Form 10-K for the year ended December 31, 2016,2017, for more information about Economic Income.
Funds From Operations, Pro Forma Funds From Operations and Adjusted Funds From Operations
Funds From Operations, or FFO is a non-GAAP financial measure that we believe, when considered with the financial statements determined in accordance with GAAP, is helpful to investors in understanding our performance because it captures features particular to real estate performance by recognizing that real estate generally appreciates over time or maintains residual value to a much greater extent than do other depreciable assets such as machinery, computers or other personal property. The National Association of Real Estate Investment Trusts, or NAREIT, defines FFO as net income or loss computed in accordance with GAAP, excluding gains from sales of, and impairment losses recognized with respect to, depreciable property, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. Adjustments for unconsolidated partnerships and joint ventures are calculated on the same basis to determine FFO. We calculate FFO attributable to Aimco common stockholders (diluted) by subtracting, if dilutive, redemption or repurchase related preferred stock issuance costs and dividends on preferred stock, and adding back dividends/distributions on dilutive preferred securities and premiums or discounts on preferred stock redemptions or repurchases.stock.
In addition to FFO, we compute Pro forma FFO and Adjusted FFO, or AFFO, which are also non-GAAP financial measures that we believe are helpful to investors in understanding our performance. Pro forma FFO represents FFO attributable to Aimco common stockholders (diluted), excluding preferred equity redemption-related amounts (adjusted for noncontrolling interests).and certain litigation costs. Preferred equity redemption-related amounts (gains or losses) are items that periodically affect our operating results and we exclude these items from our calculation of Pro forma FFO because such amounts are not representative of our operating performance. We are engaged in litigation with Airbnb to protect our property right to select our residents and their neighbors. Due to the unpredictable nature of these cases and associated legal costs, we exclude such costs from Pro forma FFO.
AFFO represents Pro forma FFO reduced by Capital Replacements, (also adjusted for noncontrolling interests), which represents our estimation of the capital additions made to replace capital assets consumed during our ownership period. When we make capital additions at an apartment community, we evaluate whether the additions enhanceextend the value, profitability or useful life of an asset as compared to its condition at the time we purchased the apartment community. We classify as Capital Improvements those capital additions that meet these criteria and we classify as Capital Replacements those that do not. AFFO is a key financial indicator that we use to evaluate our operational performance and is one of the factors that we use to determine the amounts of our dividend payments.
FFO, Pro forma FFO and AFFO should not be considered alternatives to net income, as determined in accordance with GAAP, as indications of our performance. Although we use these non-GAAP measures for comparability in assessing our performance compared to other REITs, not all REITs compute these same measures, and those who do may not compute them in the same manner. Additionally, our computation of AFFO is subject to our definition of Capital Replacement spending. Accordingly, there can be no assurance that our basis for computing these non-GAAP measures is comparable with that of other REITs.

For the three and nine months ended September 30,March 31, 2018 and 2017, and 2016, Aimco’s FFO, Pro forma FFO and AFFO are calculated as follows (in thousands):

We announced in April 2018, the planned sale of this business. Upon completion of the anticipated sale, the related taxes will be reflected within our statement of operations within gain on dispositions of real estate, inclusive of related income tax. Accordingly, we have excluded the benefit related to the reorganization from FFO.

Refer to the Liquidity and Capital Resources section for further information regarding our capital investing activities, including Capital Replacements.
The Aimco Operating Partnership does not separately compute or report FFO, Pro forma FFO or AFFO. However, based on Aimco’s method for allocation of such amounts to noncontrolling interests in the Aimco Operating Partnership, as well as limited differences between the amounts of net income attributable to Aimco’s common stockholders and the Aimco Operating Partnership’s unit holders during the periods presented, FFO, Pro forma FFO and AFFO amounts on a per unit basis for the Aimco Operating Partnership would be expected to be substantially the same as the corresponding per share amounts for Aimco.
Leverage Ratios
As discussed under the Balance Sheet and Liquidity heading, as part of our leverage strategy, weWe target the ratio of Proportionate Debt and Preferred Equity to Adjusted EBITDA to be below 7.0x and we target the ratio of Adjusted EBITDA to Adjusted Interest Expense and Preferred Dividends to be greater than 2.5x. We believe these ratios are important measures as they are commonly used by investors and analysts to assess the relative financial risk associated with balance sheets of companies within the same industry, and they are believed to be similar to measures used by rating agencies to assess entity credit quality.
We calculate our leverage ratios based on the most recent three month amounts, annualized.

Proportionate Debt, as used in our leverage ratios, is a non-GAAP measure and includes our share of the long-term, non-recourse property debt secured by apartment communities in the Real Estate portfolio, our one-year term loan, and outstanding borrowings under our revolving credit facility, reduced by our share of the cash and restricted cash of our consolidated and unconsolidated partnerships owning communities in our Real Estate portfolio, and also by our investment in the subordinate

tranches of a securitization trust that holds certain of our property debt (essentially, an investment in our own non-recourse property loans).
In our Proportionate Debt computation, we increase our recorded debt by unamortized debt issue costs because these amounts represent cash expended in earlier periods and do not reduce our contractual obligations, and we reduce our recorded debt by the amounts of cash and restricted cash on-hand (such restricted cash amounts being primarily restricted under the terms of our property debt agreements), assuming these amounts would be used to reduce our outstanding leverage. We further reduce our recorded debt by the value of our investment in a securitization trust that holds certain of our property debt, as our payments of principal and interest associated with such property debt will ultimately repay our investments in the trust.
We exclude from our leverage the non-recourse property debt obligations of consolidated partnerships served by our Asset Management business. The non-recourse property debt obligations of these partnerships are not our obligations and have limited effect on the amount of fees and other payments we expect to receive. Additionally, in April 2018, we announced the planned third quarter 2018 sale of the Asset Management business.
We believe Proportionate Debt is useful to investors as it is a measure of our net exposure to debt obligations. Proportionate Debt, as used in our leverage ratios, is calculated as set forth in the table below.
Preferred Equity, as used in our leverage ratios, represents the redemption amounts for Aimco’s preferred stock and the Aimco Operating Partnership’s preferred OP Units. Preferred Equity, although perpetual in nature, is another component of our overall leverage.
Adjusted EBITDA is a non-GAAP performance measure. We believe Adjusted EBITDA provides investors relevant and useful information because it allows investors to view income from our operations on an unleveraged basis, before the effects of taxes, depreciation and amortization, gains or losses on sales of and impairment losses related to real estate, and various other items described below.
Adjusted EBITDA represents Aimco’s share of the consolidated amount of our net income, adjusted to exclude the effect of the following items for the reasons set forth below:
Adjusted Interest Expense, defined below, to allow investors to compare a measure of our earnings before the effects of our indebtedness with that of other companies in the real estate industry;
preferred dividends, to allow investors to compare a measure of our performance before the effects of our capital structure (including indebtedness) with that of other companies in the real estate industry;
income taxes, to allow investors to measure our performance independent of income taxes, which may vary significantly from other companies within our industry due to leverage and tax planning strategies, among other considerations;factors;
depreciation and amortization, gains or losses on dispositions and impairment losses related to real estate, for similar reasons to those set forth in our discussion of FFO, Pro forma FFO and AFFO in the preceding section; and
other items, including gains on dispositions of non-depreciable assets, as these are items that periodically affect our operations but that are not necessarily representative of our ability to service our debt obligation.obligations.
While Adjusted EBITDA is a relevant measure of performance and is commonly used in leverage ratios, it does not represent net income as defined by GAAP, and should not be considered as an alternative to net income in evaluating our performance.  Further, our definition and computation of Adjusted EBITDA may not be comparable to similar measures reported by other companies.
Adjusted Interest Expense, as calculated in our leverage ratios, is a non-GAAP measure that we believe is meaningful for investors and analysts as it presents our share of current recurring interest requirements associated with leverage. Our calculation of Adjusted Interest Expense is set forth in the table below. Adjusted Interest Expense represents our proportionate share of interest expense on non-recourse property debt encumbering apartment communities in the Real Estate portfolio and interest expense on our term loan and revolving credit facility borrowings. We exclude from our calculation of Adjusted Interest Expense:
debt prepayment penalties, which are items that, from time to time, affect our operating results but are not representative of our scheduled interest obligations;
the amortization of debt issue costs, as these amounts have been expended in previous periods and are not representative of our current or prospective debt service requirements; and

the income we receive on our investment in the securitization trust that holds certain of our property debt, as this income is being generated indirectly from interest we pay with respect to property debt held by the trust.

Preferred Dividends represents the preferred dividends paid on Aimco’s preferred stock and the preferred distributions paid on the Aimco Operating Partnership’s preferred OP Units, exclusive of preferred equity redemption related amounts. We add Preferred Dividends to Adjusted Interest Expense for a more complete picture of the interest and dividend requirements of our leverage, inclusive of perpetual preferred equity.

Liquidity and Capital Resources
Liquidity
Liquidity is the ability to meet present and future financial obligations. Our primary source of liquidity is cash flow from our operations. Additional sources are proceeds from sales of apartment communities, proceeds from refinancings of existing property debt, borrowings under new property debt, borrowings under our Credit Agreement, as defined below, including our revolving credit facility and proceeds from equity offerings.
Our principal uses for liquidity include normal operating activities, payments of principal and interest on outstanding property debt, capital expenditures, dividends paid to stockholders, distributions paid to noncontrolling interest partners and acquisitions of apartment communities. We use our cash and cash equivalents and our cash provided by operating activities to meet short-term liquidity needs. In the event that our cash and cash equivalents and cash provided by operating activities are not sufficient to cover our short-term liquidity needs, we have additional means, such as short-term borrowing availability and proceeds from apartment community sales and refinancings. We may use our revolving credit facility for working capital and other short-term purposes, such as funding investments on an interim basis. We expect to meet our long-term liquidity requirements, such as debt maturities, redevelopment spending and apartment community acquisitions, through long-term borrowings (primarily non-recourse), the issuance of equity securities (including OP Units), the sale of apartment communities and cash generated from operations.
As of September 30, 2017,March 31, 2018, our primary sources of liquidity were as follows:
$38.851.9 million in cash and cash equivalents;
$47.639.0 million of restricted cash, which consists primarily of escrows related to resident security deposits and reserves and escrows held by lenders for capital additions, property taxes and insurance; and
$231.8509.1 million of available capacity to borrow under our revolving credit facility (which is more fully described below), after consideration of outstanding borrowings of $356.2$78.6 million and $12.0$12.3 million of letters of credit backed by the facility.
At September 30, 2017,March 31, 2018, we also held unencumbered apartment communities with an estimated fair market value of approximately $1.8 billion, an increase of approximately 12% from December 31, 2016.$2.0 billion. Each of the amounts presented above exclude amounts attributable to partnerships served by our Asset Management business.


Leverage and Capital Resources
The availability of credit and its related effect on the overall economy may affect our liquidity and future financing activities, both through changes in interest rates and access to financing. Currently, interest rates are low compared to historical levels and many lenders are active in the market. However, any adverse changes in the lending environment could negatively affect our liquidity. We believe we have mitigated much of this exposure by reducing our short and intermediate term maturity risk through refinancing such loans with long-dated, fixed-rate property debt. However, if property financing options become unavailable for our further debt needs, we may consider alternative sources of liquidity, such as reductions in capital spending or proceeds from apartment community dispositions.
Two credit rating agencies rate our creditworthiness and both have rated our credit and outlook as BBB- (stable), an investment grade rating. Our investment grade rating would be useful in accessing capital through the sale of bonds in private or public transactions. However, our intention and historical practice has been to raise debt capital in the form of property-level, non-recourse, long-dated, fixed-rate, amortizing debt, the cost of which is generally less than that of recourse debt and the terms of which also provide for greater balance sheet safety.
As of September 30, 2017,March 31, 2018, approximately 81.1%87.0% of our leverage consisted of property-level, non-recourse, long-dated, amortizing debt. Approximately 97.7%94.6% of this property-level debt is fixed-rate, which provides a hedge against increases in interest rates, capitalization rates and inflation. The weighted average maturity of our property-level debt was 7.17.4 years.
For property-level debt encumbering the communities in our Real Estate portfolio, $116.5$35.5 million of our unpaid principal balances mature during the remainder of 2017,2018, and on average, 9.3%12.6% of our unpaid principal balance will mature each year from 20182019 through 2020.2021.
While our primary source of leverage is property-level, non-recourse, long-dated, fixed-rate, amortizing debt, we have a Senior Secured Credit Agreement with a syndicate of financial institutions, which we refer to as our Credit Agreement. Our Credit Agreement provides for $600.0 million of revolving loan commitments. As of September 30, 2017,March 31, 2018, we had $356.2$78.6 million of outstanding borrowings under the Credit Agreementour revolving loan commitments, representing 1.8% of our total leverage. The Credit Agreement provides us with an option to expand the aggregate loan commitments, subject to customary conditions, by up to $200.0 million.
On June 30, 2017, we amended theThe Credit Agreement to providealso provides for a $250.0 million term loan to fund partially our reacquisition of limited partner interests in the Palazzo joint venture.loan. The term loan represents 5.9% of our total leverage as of March 31, 2018, matures on June 30, 2018, has a one-year extension option and bears interest at 30-day LIBOR plus 135 basis points.
As of September 30, 2017,March 31, 2018, our outstanding perpetual preferred equity represented approximately 5.2%5.3% of our total leverage. Our preferred securities are perpetual in nature; however, for illustrative purposes, we compute the weighted average maturity of our total leverage assuming a 40-year maturity for our preferred securities.
The combination of non-recourse property-level debt, borrowings under our Credit Agreement and perpetual preferred equity that comprises the majority of our total leverage, reduces our refunding and re-pricing risk. The weighted average maturity for our total leverage described above was 8.28.7 years as of September 30, 2017.March 31, 2018.
Under the Credit Agreement, we have agreed to maintain a Fixed Charge Coverage ratio of 1.40x, as well as comply with other covenants customary for similar revolving credit arrangements. For the trailing twelve month period ended September 30, 2017,March 31, 2018, our Fixed Charge Coverage ratio was 1.99x,2.02x, compared to a ratio of 1.96x for the trailing twelve month period ended September 30, 2016.March 31, 2017. We expect to remain in compliance with this covenant during the next 12 months.
Changes in Cash, and Cash Equivalents and Restricted Cash
The following discussion relates to changes in consolidated cash, and cash equivalents and restricted cash due to operating, investing and financing activities, which are presented in our condensed consolidated statements of cash flows included in Item 1 of this report.
Operating Activities
For the ninethree months ended September 30, 2017,March 31, 2018, net cash provided by operating activities was $285.0$81.3 million. Our operating cash flow is affected primarily by rental rates, occupancy levels and operating expenses related to our portfolio of apartment communities. Cash provided by operating activities for the ninethree months ended September 30, 2017,March 31, 2018, increased by $8.6$7.7 million as compared to the nine months ended September 30, 2016,2017, due to improved operating results of our Same Store communities and increased contribution from our redevelopment and lease-up communities, partially offset by lower net operating income associated with apartment communities sold in 2016.2017.

Investing Activities
For the ninethree months ended September 30, 2017,March 31, 2018, net cash used in investing activities of $274.1$171.6 million consisted primarily of the Bent Tree Apartments acquisition and capital expenditures.expenditures, partially offset by proceeds from the disposition of apartment communities. Capital expenditures totaled $266.6$75.6 million and $259.3$82.2 million during the ninethree months ended September 30,March 31, 2018 and 2017, and 2016, respectively. We generally fund capital expenditures with cash provided by operating activities and cash proceeds from apartment community sales.

Further information about the Bent Tree Apartments acquisition and three apartment community sales completed during the three months ended March 31, 2018 is included in Note 3 to the condensed consolidated financial statements in Item 1.
Capital additions for our Real Estate segment totaled $76.7 million and $70.1 million during the three months ended March 31, 2018 and 2017, respectively. We generally fund capital additions with cash provided by operating activities and cash proceeds from sales of apartment communities.
We categorize capital spending for communities in our Real Estate portfolio broadly into six primary categories:
capital replacements, which represent capital additions made to replace the consumed portion of acquired capital assets;apartment communities consumed during our period of ownership;
capital improvements, which are non-redevelopmentrepresent capital additions that are made to enhancereplace the value, profitability or useful lifeportion of anacquired apartment community from its original purchase condition;communities consumed prior to our period of ownership;
property upgrades,capital enhancements, which may include kitchen and bath remodeling, energy conservation projects and investments in longer-lived materials designed to reduce turnover costs and maintenance, all of which are generally lesser in scope than redevelopment additions and do not significantly disrupt property operations;
redevelopment additions, which represent capital additions intended to enhance the value of anthe apartment community through the ability to generate higher average rental revenues,rates, and may include costs related to entitlement, which enhance the value of a community through increased density, and costs related to renovation of exteriors, common areas or apartment homes;
development additions, which represent construction and related capitalized costs associated with development of apartment communities; and
casualty capital additions, which represent construction and related capitalized costs incurred in connection with the restoration of an assetapartment community after a casualty event such as a severe snow storm, hurricane, tornado, flood or fire.
We exclude from these measures the amounts of capital spending related to apartment communities sold or classified as held for sale at the end of the period, as well as amounts expended by consolidated partnerships served by our Asset Management business as such amounts generally do not affect the amount of cash flow we expect to receive from the operation and ultimate disposition of these communities. We have also excluded from these measures indirect capitalized costs which are allocated later in the year to apartment communities with capital additions, and their related capital spending categories.

A summary of the capital spending for these categories, along with a reconciliation of the total for these categories to the capital expenditures reported in the accompanying condensed consolidated statements of cash flowflows for the ninethree months ended September 30,March 31, 2018 and 2017, and 2016, are presented below (dollars in(in thousands):

Redevelopment/Redevelopment and Development
Information regarding our redevelopment and development communitiesWe execute redevelopments using a range of approaches. We prefer to limit risk by executing redevelopments using a phased approach, in which we renovate an apartment community in stages. Smaller phases provide us the flexibility to maintain current earnings while aligning the timing of the completed apartment homes with market demand. The following table summarizes value-creating investments related to redevelopments of this nature at September 30, 2017, is presented belowMarch 31, 2018 (dollars in millions):

(1)Redevelopments provide us with the flexibility to align the timing of completed apartment homes with market demand. As such, expected occupancy stabilization and expected NOI stabilization dates may change as market conditions evolve.
(2)This phase of redevelopment encompasses common areas, amenity improvements and the creation of a new retail space.
(3)In response to market conditions, we slowed redevelopment activities and extended the estimated time for completion.
(4)This phase of the redevelopment encompasses common areas and security system upgrades.

We also undertake ground-up development when warranted by risk-adjusted investment returns, either directly or in connection with the redevelopment of an existing apartment community or, on a more limited basis, at a new location. When smaller redevelopment phases are not possible, we may engage in redevelopment activities where an entire building or community is vacated. The following table summarizes our value-creating investments related to these developments and redevelopments at March 31, 2018 (dollars in millions):

Net investment represents the total actual or estimated investment, net of tax and other credits earned as a direct result of our redevelopment or development of the community. For phased redevelopments, potential net investment relates to the current phase of the redevelopment.
Net Operating IncomeStabilized Occupancy represents the period in which we expect to achieve stabilized occupancy generally greater than 90%.
NOI Stabilization represents the period in which we expect the communities to achieve stabilized rents and operating costs, generally five quarters after occupancy stabilization.
During the ninethree months ended September 30, 2017,March 31, 2018, we invested $121.2$46.8 million in ongoing redevelopment and development projects.
During the nine months ended September 30, 2017, we completed construction of the third tower at Park Towne Place in Center City, Philadelphia. As of September 30, 2017 this tower was 74% leased at rates consistent with underwriting. We expect this tower to be more than 90% leased by year-end, as are the first two towers redeveloped at the community.
Also indevelopment. In Center City, Philadelphia, during the nine months ended September 30, 2017, we completed redevelopment and the lease-up of the 534 apartment homes at The Sterling and substantially completed the reconfiguration of the second floor commercial space, upgrades to the third and fourth floor commercial space and upgrades to residential common areas.
In the past three years, we have leased more than 1,100 redeveloped apartment homes in Center City, Philadelphia. Basedcontinued construction on these results, we decided to proceed with a $40.0 million redevelopment of the fourth and final tower atof Park Towne Place. De-leasingInitial move-ins have occurred and at the end of April, 31% of the fourth tower was pre-leased.
Construction is underway, on plan and construction on this tower is scheduled to commence by year end.
In addition to the redevelopments described above, during the nine months ended September 30, 2017 we continued redevelopment of three ongoing projects in Los Angeles and San Jose, California and Lombard, Illinois and commenced redevelopmentsbudget at four apartment communities in Miami, Minneapolis, and Los Angeles, which are summarized in the table above.
In 2014, we acquired Eastpointe, a “C” property located in Boulder, Colorado. Over the past two years, we have planned and entitled a newParc Mosaic, our $117.0 million, 226 apartment home community to be known as Parc Mosaic. De-leasingbeing developed on the site of our former Eastpointe is underway and construction ofcommunity in Boulder, Colorado. We expect Parc Mosaic is scheduled to commence by year end.will be available for occupancy in the summer of 2019.

Inclusive of the redevelopment and development projects discussed above, during the nine months ended September 30, 2017 we expanded our redevelopment and development pipeline by $223.1 million. TheOur total estimated net investment for thesein redevelopment and development communities is $710.4$432.8 million with a projected weighted average net operating income yield on these investments of 6.1%, assuming untrended rents. Of this total, $481.4$279.0 million has been funded. We expect to fund the remaining redevelopment and development investment with proceeds from our planned sale of the Asset Management business and Hunters Point communities.
During the three months ended March 31, 2018, we leased 59 apartment homes at our redevelopment communities. As of March 31, 2018, our exposure to lease-up at active redevelopment and development projects was approximately 527 apartment homes, of which 201 were in the fourth tower of Park Towne Place and 215 were being constructed at Parc Mosaic.
We expect our total development and redevelopment spending to range from $150$120 million to $170$200 million for the year ending December 31, 2017.2018.
Financing Activities
For the ninethree months ended September 30, 2017,March 31, 2018, net cash used inprovided by financing activities of $16.4$86.8 million was primarily attributed to proceeds from non-recourse property debt and net borrowings on our reacquisition of the limited partner interests in the Palazzo joint venture,revolving credit facility, partially offset by dividends paid to common security holders, distributions paid to noncontrolling interests and principal payments on property loans, mostly offset by proceeds from the term loan, net borrowings on our revolving credit facility and proceeds from non-recourse property debt.loans.
Net borrowings on our revolving credit facility primarily relate to the timing of apartment community acquisitions and dispositions and of property debt financing activities and apartment community dispositions planned during 2017, as well as the timing of our reacquisition of the limited partner interests in the Palazzo joint venture. activities.
Proceeds from non-recourse property debt borrowings during the period consisted of the closing of sixtwo fixed-rate, amortizing, non-recourse property loans totaling $162.2$242.0 million. OnThese loans have 10-year terms and a weighted average basis, these loans have a term of 9.3 years and an interest rate of 3.6%3.48%, 129126 basis points more than the corresponding Treasury rate at the time of pricing. The net effect of 2018 fixed-rate property debt refinancing activities has been to lower our weighted average fixed interest rate by nearly 10 basis points since December 31, 2017, to 4.55%, reducing prospective interest expense by more than $3.0 million.
Proceeds from non-recourse property debt borrowing during the period also included the closing of two non-recourse, variable-rate property loans totaling $118.6 million. These loans each have a five-year term and bear interest at 30-day LIBOR plus 1.25%.

The five-year terms fill a hole in our laddered maturities and, taken together with the planned repayment of the variable term loan, reduce our exposure to increasing short-term interest rates to less than 7% of our leverage.
We like the discipline of financing our investments in real estate through the use of fixed-rate, amortizing, non-recourse property debt, as the amortization gradually reduces our leverage and reduces our refunding risk, and the fixed-rate provides a hedge against increases in interest rates.rates, and the non-recourse feature avoids entity risk.
Principal payments on property loans during the period totaled $250.7$206.3 million, consisting of scheduled principal amortization of $64.3$20.4 million and repayments of $186.4$185.9 million.
Net cash used in financing activities also includes $191.3$73.7 million of payments to equity holders, as further detailed in the table below.

ITEM 3.Quantitative and Qualitative Disclosures About Market Risk
As of September 30, 2017,March 31, 2018, on a consolidated basis, we had approximately $83.1$201.3 million of variable-rate property debt outstanding, and $606.2$328.6 million of variable-rate borrowings under our Credit Agreement.Agreement, including a $250.0 million term loan that matures on June 30, 2018 and has a one-year extension option. We estimate that an increasea change in 30-day LIBOR of 100 basis points with constant credit risk spreads would result in our net income, the amount ofreduce or increase net income attributable to Aimco common stockholders and the amount of net income attributable to the Aimco Operating Partnership’s common unitholders being reduced by approximately $6.7$5.1 million on an annual basis. We estimate that a decrease in 30-day LIBOR of 100 basis points would increase the amounts of our net income by a similar amount.
At September 30, 2017, weMarch 31, 2018, our Real Estate segment had approximately $133.6$90.9 million in cash and cash equivalents and restricted cash, a portion of which bearbears interest at variable rates, andwhich may partially mitigate the effect of an increaseoffset somewhat a change in variable rates on our variable-rate debt discussed above.
We estimate the fair value for debt instruments as described in Note 6 to the condensed consolidated financial statements in Item 1. The estimated fair value of total indebtedness associated with the Real Estate portfolio was approximately $4.2 billion at September 30, 2017, inclusive of a $62.3 million mark-to-market liability. Theapproximated its carrying value of non-recourse property debt of the partnerships served by our Asset Management business approximated its estimated fair value at September 30, 2017 and DecemberMarch 31, 2016. The mark-to-market liability increased by $4.7 million as compared to the mark-to-market liability at December 31, 2016.2018.
If market rates for consolidated fixed-rate debt in our Real Estate segment were higher by 100 basis points with constant credit risk spreads, the estimated fair value of consolidated debt discussed above would decrease from $4.4$4.0 billion in the aggregate to $4.3$3.9 billion. If market rates for consolidated debt discussed above were lower by 100 basis points with constant credit risk spreads, the estimated fair value of consolidated fixed-rate debt would increase from $4.4$4.0 billion in the aggregate to $4.6$4.1 billion.
