NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1. Organization, Basis of Presentation and Summary of Significant Accounting Policies

Organization

Acadia Realty Trust and subsidiaries (collectively, the “Company”) is a fully-integrated equity real estate investment trust (“REIT”) focused on the ownership, acquisition, development, and management of retail properties located primarily in high-barrier-to-entry, supply-constrained, densely-populated metropolitan areas in the United States.

All of the Company’s assets are held by, and all of its operations are conducted through, Acadia Realty Limited Partnership (the “Operating Partnership”) and entities in which the Operating Partnership owns an interest. As of March 31, 2018 and December 31, 2017, the Company controlled approximately 94% and 95%, respectively, of the Operating Partnership as the sole general partner and is entitled to share, in proportion to its percentage interest, in the cash distributions and profits and losses of the Operating Partnership. The limited partners primarily represent entities or individuals that contributed their interests in certain properties or entities to the Operating Partnership in exchange for common or preferred units of limited partnership interest (“Common OP Units” or “Preferred OP Units”) and employees who have been awarded restricted Common OP Units (“LTIP Units”) as long-term incentive compensation (Note 13). Limited partners holding Common OP and LTIP Units are generally entitled to exchange their units on a one-for-one basis for common shares of beneficial interest of the Company (“Common Shares”). This structure is referred to as an umbrella partnership REIT or “UPREIT.”

As of March 31, 2018, the Company has ownership interests in 118 properties within its core portfolio, which consist of those properties either 100% owned, or partially owned through joint venture interests, by the Operating Partnership, or subsidiaries thereof, not including those properties owned through its funds (“Core Portfolio”). The Company also has ownership interests in 57 properties within its opportunity funds, Acadia Strategic Opportunity Fund II, LLC (“Fund II”), Acadia Strategic Opportunity Fund III LLC (“Fund III”), Acadia Strategic Opportunity Fund IV LLC (“Fund IV”), and Acadia Strategic Opportunity Fund V LLC (“Fund V”). Acadia Strategic Opportunity Fund I, LP (“Fund I,” together with Funds II, III, IV, and V, the “Funds”) was liquidated in 2015. The 175 Core Portfolio and Fund properties primarily consist of street and urban retail, and suburban shopping centers. In addition, the Company, together with the investors in the Funds, invest in operating companies through Acadia Mervyn Investors I, LLC (“Mervyns I,” which was liquidated in 2018), Acadia Mervyn Investors II, LLC (“Mervyns II”) and Fund II, all on a non-recourse basis. The Company consolidates the Funds as it has (i) the power to direct the activities that most significantly impact the Funds’ economic performance, (ii) is obligated to absorb the Funds’ losses and (iii) has the right to receive benefits from the Funds that could potentially be significant.

The Operating Partnership is the sole general partner or managing member of the Funds and Mervyns I and II and earns fees or priority distributions for asset management, property management, construction, development, leasing, and legal services. Cash flows from the Funds and Mervyns I and II are distributed pro-rata to their respective partners and members (including the Operating Partnership) until each receives a certain cumulative return (“Preferred Return”) and the return of all capital contributions. Thereafter, remaining cash flow is distributed 20% to the Operating Partnership (“Promote”) and 80% to the partners or members (including the Operating Partnership). All transactions between the Funds and the Operating Partnership have been eliminated in consolidation.

The following table summarizes the general terms and Operating Partnership’s equity interests in the Funds and Mervyns II (dollars in millions):

Entity	Formation Date	Operating Partnership Share of Capital	Capital Called as of March 31, 2018		Unfunded Commitment		Equity Interest Held By Operating Partnership (a)	Preferred Return	Total Distributions as of March 31, 2018 (b)
Fund II and Mervyns II	6/2004	28.33%	$	347.1	$	—	28.33%	8%	$	131.6
Fund III	5/2007	24.54%	411.5		38.5		24.54%	6%	551.9
Fund IV	5/2012	23.12%	412.7		117.3		23.12%	6%	131.5
Fund V	8/2016	20.10%	45.8		474.2		20.10%	6%	—

__________

(a) Amount represents the current economic ownership at March 31, 2018, which could differ from the stated legal ownership based upon the cumulative preferred returns of the respective fund.

(b) Represents the total for the Funds, including the Operating Partnership and noncontrolling interests’ shares.

Basis of Presentation

Segments

At March 31, 2018, the Company had three reportable operating segments: Core Portfolio, Funds and Structured Financing. The Company’s chief operating decision maker may review operational and financial data on a property basis and does not differentiate properties on a geographical basis for purposes of allocating resources or capital. Each property is considered a separate operating segment; however, each property on a stand-alone basis represents less than 10% of revenues, profit or loss, and assets of the combined reported operating segment and meets the majority of the aggregations criteria under the applicable standard.

Principles of Consolidation

The consolidated financial statements include the consolidated accounts of the Company and its investments in partnerships and limited liability companies in which the Company has control in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810 “Consolidation” (“ASC Topic 810”). The ownership interests of other investors in these entities are recorded as noncontrolling interests. All significant intercompany balances and transactions have been eliminated in consolidation. Investments in entities for which the Company has the ability to exercise significant influence over, but does not have financial or operating control, are accounted for using the equity method of accounting. Accordingly, the Company’s share of the earnings (or losses) of these entities are included in consolidated net income.

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. Operating results for the interim periods presented are not necessarily indicative of the results that may be expected for the full fiscal year. The information furnished in the accompanying consolidated financial statements reflects all adjustments that, in the opinion of management, are necessary for a fair presentation of the aforementioned consolidated financial statements for the interim periods. Such adjustments consisted of normal recurring items.

These consolidated financial statements should be read in conjunction with the Company’s 2017 Annual Report on Form 10-K, as filed with the SEC on February 27, 2018.

Use of Estimates

GAAP requires the Company’s management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The most significant assumptions and estimates relate to the valuation of real estate, depreciable lives, revenue recognition and the collectability of notes receivable and rents receivable. Application of these estimates and assumptions requires the exercise of judgment as to future uncertainties and, as a result, actual results could differ from these estimates.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update(“ASU”) No. 2014-09, Revenue from Contracts with Customers. ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 does not apply to the Company’s lease revenues, but will apply to reimbursed tenant costs. Additionally, this guidance modifies disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued ASU 2015-14, which defers the effective date of ASU 2014-09 for all entities by one year, until years beginning in 2018, with early adoption permitted but not before 2017. Entities may adopt ASU 2014-09 using either a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or a modified retrospective approach with the cumulative effect, recognized at the date of adoption. Substantially all of the Company’s revenue is derived from its leases and therefore falls outside of the scope of this guidance. The Company implemented the standard using the modified retrospective approach; however, there was no cumulative effect required to be recognized in retained earnings at the date of application. With respect to its fee-derived revenue, the Company had no changes to the timing of the Company’s revenue recognition. However, the recognition of gains on sales of properties may be impacted prospectively under limited circumstances under which collectability may not be reasonably assured or if the Company has continuing involvement with a sold property.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows – Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 provides guidance on certain specific cash flow issues, including, but not limited to, debt prepayment or extinguishment costs, contingent consideration payments made after a business combination and distributions received from equity method investees. ASU 2016-15 is effective for periods beginning after December 15, 2017, with early adoption permitted and shall be applied retrospectively where practicable. The Company adopted ASU 2016-15 effective January 1, 2018 and elected the “cumulative distribution approach” whereby distributions received from equity method investments would be classified as cash flows from operations to the extent of equity earnings and then as cash flows from investing activities thereafter. Upon the adoption, the Company reclassified $7.3 million of its cash inflows from investing activities to cash flows from operating activities in its historical presentation of cash flows related to its equity method investments for the three months ended March 31, 2017.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 is effective for public business entities in fiscal years beginning after December 15, 2017, with early adoption permitted. The Company adopted this guidance effective January 1, 2018. Upon the adoption, the Company reclassified $1.0 million of its cash inflows from operating activities to change in cash and restricted cash in its historical presentation of cash flows for the three months ended March 31, 2017.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations – Clarifying the Definition of a Business. ASU 2017-01 clarifies that to be considered a business, the elements must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output. The new standard illustrates the circumstances under which real estate with in-place leases would be considered a business and provides guidance for the identification of assets and liabilities in purchase accounting. ASU 2017-01 is effective for periods beginning after December 15, 2017 and has been adopted by the Company effective January 1, 2018. It is expected that the new standard will reduce the number of future real estate acquisitions that will be accounted for as business combinations and, therefore, reduce the amount of acquisition costs that will be expensed. Accordingly, the Company capitalized $0.1 million of acquisition costs during the three months ended March 31, 2018 and expensed $0.3 million of acquisition costs during the three months ended March 31, 2017.

In January 2017, the FASB issued ASU No. 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments – Equity Method and Joint Ventures (Topic 323). ASU 2017-03 amends certain SEC guidance in the FASB Accounting Standards Codification in response to SEC staff announcements made during 2016 Emerging Issues Task Force (“EITF”) meetings which addressed (i) the additional qualitative disclosures that a registrant is expected to provide when it cannot reasonably estimate the impact that ASUs 2014-09, 2016-02 and 2016-13 will have in applying the guidance in Staff Accounting Bulletin Topic 11.M and (ii) guidance in ASC 323 related to the amendments made by ASU 2014-01 regarding use of the proportional amortization method in accounting for investments in qualified affordable housing projects (announcement made at the November 17, 2016, EITF meeting). The Company adopted 2017-03 effective January 1, 2018. The adoption of ASU 2017-03 did not have a material impact on the Company’s consolidated financial statements.

In February 2017, the FASB issued ASU 2017-05, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets, which amends the guidance on nonfinancial assets in ASC 610-20. The amendments clarify that (i) a financial asset is within the scope of ASC 610-20 if it meets the definition of an in substance nonfinancial asset and may include nonfinancial assets transferred within a legal entity to a counter-party, (ii) an entity should identify each distinct nonfinancial asset or in substance nonfinancial asset promised to a counter-party and de-recognize each asset when a counter-party obtains control of it, and (iii) an entity should allocate consideration to each distinct asset by applying the guidance in ASC 606 on allocating the transaction price to performance obligations. Further, ASU 2017-05 provides guidance on accounting for partial sales of nonfinancial assets. The amendments are effective at the same time as the amendments in ASU 2014-09. The Company adopted ASU 2017-05 effective January 1, 2018. The adoption of ASU 2017-05 did not have a material impact on the Company's consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, which clarifies the scope of modification accounting with respect to changes to the terms or conditions of a share-based payment award. Modification accounting would not apply if a change to an award does not affect the total current fair value (or other applicable measurement), vesting conditions, or the classification of the award. For all entities, ASU 2017-09 is effective prospectively for awards modified in fiscal years beginning after December 15, 2017. The Company adopted ASU 2017-09 effective January 1, 2018. The adoption of ASU 2017-09 did not have a material impact on the Company's consolidated financial statements because the Company has not had significant modifications of its awards.

In August 2017, the Financial Accounting Standards Board issued ASU 2017-12, Derivatives and Hedging:Targeted Improvements to Accounting for Hedging Activities. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, with early adoption, including adoption in an interim period, permitted. The Company early adopted ASU 2017-12 effective January 1, 2018 and the adoption of ASU 2017-12 did not have a material impact on the Company's consolidated financial statements.

In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118, which allowed public companies to record provisional amounts in earnings for the year ended December 31, 2017 due to the complexities involved in accounting for the enactment of the Tax Cuts and Jobs Act. ASU 2018-05 was effective upon issuance. The Company recognized the estimated income tax effects of the Tax Cuts and Jobs Act in its 2017 Consolidated Financial Statements in accordance with SEC Staff Accounting Bulletin No. 118.

Recently Issued Accounting Pronouncements

In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. These amendments provide financial statement preparers with an option to reclassify stranded tax effects within accumulated other comprehensive income to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recorded. This guidance is effective for fiscal years beginning after December 15, 2018, and interim periods therein. Early adoption is permitted. We are currently assessing the impact this guidance will have on our consolidated financial statements.

Core Portfolio

Acquisition of Unconsolidated Investment

On January 4, 2017, an entity in which the Company owns a 20% noncontrolling interest (the “Renaissance Portfolio”), acquired a 6,200 square foot property in Alexandria, Virginia referred to as (“907 King Street”) for $3.0 million. The Renaissance Portfolio is now a 213,000 square-foot portfolio of 18 mixed-use properties, 16 of which are located in Georgetown, Washington D.C. and two of which are located in Alexandria, Virginia.

Brandywine Portfolio, Market Square and Town Center

The Company owns an interest in an approximately one million square foot retail portfolio (the “Brandywine Portfolio” joint venture) located in Wilmington, Delaware, which includes two properties referred to as “Market Square” and “Town Center.” Prior to the second quarter of 2016, the Company had a controlling interest in the Brandywine Portfolio, and it was therefore consolidated within the Company’s financial statements. During April 2016, the arrangement with the partners of the Brandywine Portfolio was modified to change the legal ownership from a partnership to a tenancy-in-common interest, as well as to provide certain participating rights to the outside partners. As a result of these modifications, the Company de-consolidated the Brandywine Portfolio and accounted for its interest under the equity method of accounting effective May 1, 2016. Furthermore, as the owners of the Brandywine Portfolio had consistent ownership interests before and after the modification and the underlying net assets were unchanged, the Company reflected the change from consolidation to equity method based upon its historical cost. The Brandywine Portfolio and Market Square ventures do not include the property held by Brandywine Holdings, an entity consolidated by the Company.

Additionally, in April 2016, the Company repaid the outstanding balance of $140.0 million of non-recourse debt collateralized by the Brandywine Portfolio and provided a note receivable collateralized by the partners’ tenancy-in-common interest in the Brandywine Portfolio for their proportionate share of the repayment. On May 1, 2017, the Company exchanged $16.0 million of the $153.4 million notes receivable (the “Brandywine Notes Receivable”) (Note 3) plus accrued interest of $0.3 million for one of the partner’s 38.89% tenancy-in-common interests in Market Square. The Company already had a 22.22% interest in Market Square and continued to apply the equity method of accounting for its aggregate 61.11% noncontrolling interest in Market Square and its 22.22% interest in Town Center through November 16, 2017. The incremental investment in Market Square was recorded at $16.3 million and the excess of this amount over the venture’s book value associated with this interest, or $9.8 million, was being amortized over the remaining depreciable lives of the venture’s assets through November 16, 2017. On November 16, 2017, the Company exchanged an additional $16.0 million of Brandywine Notes Receivable plus accrued interest of $0.6 million for the remaining 38.89% interest in Market Square, thereby obtaining a 100% controlling interest in the property. The exchange was deemed to be a business combination and as a result, the property was consolidated and a gain on change of control of $5.6 million was recorded (Note 2).

On November 16, 2017, the Company exchanged $60.7 million of the Brandywine Notes Receivable plus accrued interest of $0.9 million for one of the partner’s 38.89% tenancy-in-common interests in Town Center. The incremental investment in Town Center was recorded at $61.6 million and the excess of this amount over the venture’s book value associated with this interest, or $34.5 million, will be amortized over the remaining depreciable lives of the venture’s assets. The Company previously had a 22.22% interest in Town Center which then became 61.11% following the November 2017 transaction.

On March 28, 2018, the Company exchanged $22.0 million of its Brandywine Notes Receivable plus accrued interest of $0.3 million for one of the partner’s 14.11% tenancy-in-common interests in Town Center. The incremental investment in Town Center was recorded at $22.3 million and the excess of this amount over the venture’s book value associated with this interest, or $12.7 million, will be amortized over the remaining depreciable lives of the venture’s assets. The Company continues to apply the equity method of accounting for its aggregate 75.22% noncontrolling interest in Town Center after the March 2018 transaction.

At March 31, 2018, $38.7 million of the Brandywine Note Receivable remains outstanding (Note 3), which is collateralized by the remaining 24.78% undivided interest in Town Center.

Fund Investments

Mervyn’s I & II

In 2017, Mervyn’s I and Mervyn’s II received a total of $1.1 million in distributions from certain investments. The Company had already reduced the carrying amount of these investments to zero, and consequently the entire amount received has been reflected as equity in earnings and gains of unconsolidated affiliates in the consolidated statements of income.

Albertson’s

“Other” includes Fund II’s cost method investment in Albertson’s supermarkets among other investments. In 2017, the Company received $2.4 million in distributions from Albertson’s and reduced the carrying amount of its investment in Albertson’s to zero, reflecting the remaining $2.0 million as equity in earnings and gains of unconsolidated affiliates in the consolidated statements of income.

On June 30, 2017, Fund IV completed the disposition of 1701 Belmont Avenue, for $5.6 million less $2.9 million debt repayments for net proceeds of $2.7 million, resulting in a gain on disposition of $3.3 million at the property level, of which the Fund’s share was $3.3 million, which is included in equity in earnings and gains from unconsolidated affiliates in the consolidated statements of income. The Operating Partnership’s proportionate share of the gain was $0.8 million, net of noncontrolling interests.

On October 3 and December 21, 2017, Fund IV’s Broughton Street Portfolio venture sold a total of five properties for aggregate proceeds of $11.0 million resulting in a net gain of $1.2 million at the property level, of which the Fund’s share was $0.6 million, which is included in equity in earnings and gains from unconsolidated affiliates in the consolidated financial statements.

(b) Includes $520.2 million and $504.0 million, respectively, of variable-rate debt that has been fixed with interest rate swap agreements as of the periods presented.

(c) Includes $143.8 million and $141.1 million, respectively, of variable-rate debt that is subject to interest cap agreements.

Credit Facility

On February 20, 2018, the Company entered into a $500.0 million senior unsecured credit facility (the “Credit Facility”), comprised of a $150.0 million senior unsecured revolving credit facility (the “Revolver”), and a $350.0 million senior unsecured term loan (the “Term Loan”). The Credit Facility refinanced the Company’s existing $300.0 million credit facility (comprised of the $150.0 million Core unsecured revolving line of credit and the $150.0 million term loan), $150.0 million in Core unsecured term loans and repaid a $40.4 million mortgage secured by its 664 North Michigan Property. The Revolver and Term Loans mature on March 31, 2022 and March 31, 2023, respectively.

Mortgages Payable

During the three months endedMarch 31, 2018, the Company obtained two new non-recourse Fund mortgages totaling $39.8 million with a weighted-average interest rate of LIBOR + 2.17% collateralized by two properties and maturing in 2021. The Company entered into interest rate swap contracts to effectively fix the variable portion of the interest rates of one of these obligations with a notional value of $16.9 million at an interest rate of 2.41%. During the three months endedMarch 31, 2018, the Company repaid one Core mortgage in full, which had a total balance of $40.4 million and a weighted-average interest rate of LIBOR + 1.65%, and made scheduled principal payments of $1.9 million. At March 31, 2018 and December 31, 2017, the Company’s mortgages were collateralized by 43 and 42 properties, respectively, and the related tenant leases. Certain loans are cross-collateralized and contain cross-default provisions. The loan agreements contain customary representations, covenants and events of default. Certain loan agreements require the Company to comply with affirmative and negative covenants, including the maintenance of debt service coverage and leverage ratios. A portion of the Company’s variable-rate mortgage debt has been effectively fixed through certain cash flow hedge transactions (Note 8).

The mortgage loan related to Brandywine Holdings in the Company’s Core Portfolio amounted to $26.3 million and was in default at March 31, 2018 and December 31, 2017. This loan bears interest at 6.00%, excluding default interest of 5%, and is collateralized by a property, in which the Company holds a 22% controlling interest. In April 2017, the lender on this mortgage initiated a lawsuit against the Company for the full balance of the principal, accrued interest as well as penalties and fees aggregating approximately $32.9 million. The Company’s management believes that the mortgage is not recourse to the Company and that the suit is without merit.

Unsecured Notes Payable

Unsecured notes payable for which total availability was $65.5 million and $70.3 million at March 31, 2018 and December 31, 2017, respectively, are comprised of the following:

• As discussed above, the Core unsecured term loans totaling $300.0 million were refinanced in February 2018, into one $350.0 million term loan with an interest rate of LIBOR+1.25% and maturing in March 2023. The outstanding balance of the Core term loans was $350.0 million and $300.0 million, respectively, at March 31, 2018 and December 31, 2017. The Company entered into an interest rate swap contract to effectively fix the variable portion of the interest rate with a notional value of $50.0 million at an interest rate of 2.80%.

• Fund II has a $40.0 million term loan secured by the real estate assets of City Point Phase II and guaranteed by the Company and the Operating Partnership. The outstanding balance of the Fund II term loan was $31.5 million at each of March 31, 2018 and December 31, 2017. Total availability was $8.5 million, at each of March 31, 2018 and December 31, 2017.

• At Fund IV there are a $41.8 million bridge facility and a $21.5 million subscription line. The outstanding balance of the Fund IV bridge facility was $40.8 million at each of March 31, 2018 and December 31, 2017. Total availability was $1.0 million at each of March 31, 2018 and December 31, 2017. The outstanding balance of the Fund IV subscription line was $0.0 million and total available credit was $14.1 million at each of March 31, 2018 and December 31, 2017, reflecting letters of credit of $7.4 million.

• Fund V has a $150.0 million subscription line collateralized by Fund V’s unfunded capital commitments and guaranteed by the Operating Partnership. The outstanding balance and total available credit of the Fund V subscription line was $108.1 million and $41.9 million, respectively at March 31, 2018. The outstanding balance and total available credit of the Fund V subscription line was $103.3 million and $46.7 million, respectively at December 31, 2017.

8. Financial Instruments and Fair Value Measurements

The fair value of an asset is defined as the exit price, which is the amount that would either be received when an asset is sold or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The guidance establishes a three-tier fair value hierarchy based on the inputs used in measuring fair value. These tiers are: Level 1, for which quoted market prices for identical instruments are available in active markets, such as money market funds, equity securities, and U.S. Treasury securities; Level 2, for which there are inputs other than quoted prices included within Level 1 that are observable for the instrument, such as certain derivative instruments including interest rate caps and interest rate swaps; and Level 3, for financial instruments or other assets/liabilities that do not fall into Level 1 or Level 2 and for which little or no market data exists, therefore requiring the Company to develop its own assumptions.

Items Measured at Fair Value on a Recurring Basis

The methods and assumptions described below were used to estimate the fair value of each class of financial instrument. For significant Level 3 items, the Company has also provided the unobservable inputs along with their weighted-average ranges.

Money Market Funds — The Company has money market funds, which are included in Cash and cash equivalents in the consolidated financial statements, are comprised of government securities and/or U.S. Treasury bills. These funds were classified as Level 1 as we used quoted prices from active markets to determine their fair values.

Derivative Assets — The Company has derivative assets, which are included in Other assets, net in the consolidated financial statements, are comprised of interest rate swaps and caps. The derivative instruments were measured at fair value using readily observable market inputs, such as quotations on interest rates, and were classified as Level 2 as these instruments are custom, over-the-counter contracts with various bank counterparties that are not traded in an active market. See “Derivative Financial Instruments,” below.

Derivative Liabilities — The Company has derivative liabilities, which are included in Accounts payable and other liabilities in the consolidated financial statements, are comprised of interest rate swaps and caps. These derivative instruments were measured at fair value using readily observable market inputs, such as quotations on interest rates, and were classified as Level 2 because they are custom, over-the-counter contracts with various bank counterparties that are not traded in an active market. See “Derivative Financial Instruments,” below.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

The Company did not have any transfers into or out of Level 1, Level 2, and Level 3 measurements during the three months endedMarch 31, 2018 or 2017.

The following table presents the Company’s fair value hierarchy for those assets and liabilities measured at fair value on a recurring basis (in thousands):

	March 31, 2018						December 31, 2017
	Level 1		Level 2		Level 3		Level 1		Level 2		Level 3

Derivative financial instruments	—		9,958		—		—		4,402		—
Liabilities
Derivative financial instruments	—		1,238		—		—		1,467		—

In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

Items Measured at Fair Value on a Nonrecurring Basis (Including Impairment Charges)

The Company did not record any impairment charges during the three months endedMarch 31, 2018 or 2017.

All of the Company’s derivative instruments have been designated as cash flow hedges and hedge the future cash outflows on variable-rate debt (Note 7). It is estimated that approximately $1.1 million included in accumulated other comprehensive (loss) income related to derivatives will be reclassified to interest expense in the 2018 results of operation. As of March 31, 2018 and December 31, 2017, no derivatives were designated as fair value hedges or hedges of net investments in foreign operations. Additionally, the Company does not use derivatives for trading or speculative purposes and currently does not have any derivatives that are not designated hedges.

Risk Management Objective of Using Derivatives

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of its debt funding and, from time to time, through the use of derivative financial instruments. The Company enters into derivative financial instruments to manage exposures that result in the receipt or payment of future known and uncertain cash amounts, the values of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s investments and borrowings.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

The Company is exposed to credit risk in the event of non-performance by the counterparties to the Swaps if the derivative position has a positive balance. The Company believes it mitigates its credit risk by entering into Swaps with major financial institutions. The Company continually monitors and actively manages interest costs on its variable-rate debt portfolio and may enter into additional interest rate swap positions or other derivative interest rate instruments based on market conditions. The Company has not entered, and does not plan to enter, into any derivative financial instruments for trading or speculative purposes.

The following table presents the location in the financial statements of the income (losses) recognized related to the Company’s cash flow hedges (in thousands):

Credit Risk-Related Contingent Features

The Company has agreements with each of its Swap counterparties that contain a provision whereby if the Company defaults on certain of its unsecured indebtedness the Company could also be declared in default on its swaps, resulting in an acceleration of payment under the swaps.

Other Financial Instruments

The Company’s other financial instruments had the following carrying values and fair values as of the dates shown (dollars in thousands):

__________

(a) The Company determined the estimated fair value of these financial instruments using a discounted cash flow model with rates that take into account the credit of the borrower or tenant, where applicable, and interest rate risk. The Company also considered the value of the underlying collateral, taking into account the quality of the collateral, the credit quality of the borrower, the time until maturity and the current market interest rate environment.

(b) Represents Fund II’s cost-method investment in Albertson’s supermarkets (Note 4).

(c) The Company determined the estimated fair value of the unsecured notes payable and unsecured line of credit using quoted market prices in an open market with limited trading volume where available. In cases where there was no trading volume, the Company determined the estimated fair value using a discounted cash flow model using a rate that reflects the average yield of similar market participants.

The Company’s cash and cash equivalents, restricted cash, accounts receivable, accounts payable and certain financial instruments included in other assets and other liabilities had fair values that approximated their carrying values at March 31, 2018.

9. Commitments and Contingencies

The Company is involved in various matters of litigation arising in the normal course of business. While the Company is unable to predict with certainty the amounts involved, the Company’s management and counsel are of the opinion that, when such litigation is resolved, the Company’s resulting liability, if any, will not have a significant effect on the Company’s consolidated financial position, results of operations, or liquidity. The Company's policy is to accrue legal expenses as they are incurred.

Commitments and Guaranties

In conjunction with the development and expansion of various properties, the Company has entered into agreements with general contractors for the construction or development of properties aggregating approximately $87.1 million and $92.2 million as of March 31, 2018 and December 31, 2017, respectively.

At each of March 31, 2018 and December 31, 2017, the Company had letters of credit outstanding of $19.7 million. The Company has not recorded any obligation associated with these letters of credit. The majority of the letters of credit are collateral for existing indebtedness and other obligations of the Company.

Preferred OP Units

There were no issuances of Preferred OP Units during the three months endedMarch 31, 2018.

In 1999 the Operating Partnership issued 1,580 Series A Preferred OP Units in connection with the acquisition of a property, which have a stated value of $1,000 per unit, and are entitled to a preferred quarterly distribution of the greater of (i) $22.50 (9% annually) per Series A Preferred OP Unit or (ii) the quarterly distribution attributable to a Series A Preferred OP Unit if such unit was converted into a Common OP Unit. Through March 31, 2018, 1,392 Series A Preferred OP Units were converted into 185,600 Common OP Units and then into Common Shares. The 188 remaining Series A Preferred OP Units are currently convertible into Common OP Units based on the stated value divided by $7.50. Either the Company or the holders can currently call for the conversion of the Series A Preferred OP Units at the lesser of $7.50 or the market price of the Common Shares as of the conversion date.

During 2016, the Operating Partnership issued 442,478 Common OP Units and 141,593 Series C Preferred OP Units to a third party to acquire Gotham Plaza (Note 4). The Series C Preferred OP Units have a value of $100.00 per unit and are entitled to a preferred quarterly distribution of $0.9375 per unit and are convertible into Common OP Units at a rate based on the share price at the time of conversion. If the share price is below $28.80 on the conversion date, each Series C Preferred OP Unit will be convertible into 3.4722 Common OP Units. If the share price is between $28.80 and $35.20 on the conversion date, each Series C Preferred OP Unit will be convertible into a number of Common OP Units equal to $100.00 divided by the closing share price. If the share price is above $35.20 on the conversion date, each Series C Preferred OP Unit will be convertible into 2.8409 Common OP Units. The Series C Preferred OP Units have a mandatory conversion date of December 31, 2025, at which time all units that have not been converted will automatically be converted into Common OP Units based on the same calculations. Through March 31, 2018, 5,000 Series C Preferred OP Units were converted into 17,165 Common OP Units and then into Common Shares.

11. Leases

Operating Leases

The Company is engaged in the operation of shopping centers and other retail properties that are either owned or, with respect to certain shopping centers, operated under long-term ground leases that expire at various dates through June 20, 2066, with renewal options. Space in the shopping centers is leased to tenants pursuant to agreements that provide for terms ranging generally from one month to ninety-nine years and generally provide for additional rents based on certain operating expenses as well as tenants’ sales volumes.

The Company leases land at seven of its shopping centers, which are accounted for as operating leases and generally provide the Company with renewal options. Ground rent expense was $0.4 million and $0.8 million (including capitalized ground rent at a property under development of $0.2 million and $0.1 million) for the three months endedMarch 31, 2018 and 2017, respectively. The leases terminate at various dates between 2020 and 2066. These leases provide the Company with options to renew for additional terms aggregating from 25 to 71 years. The Company also leases space for its corporate office. Office rent expense under this lease was $0.2 million for each of the three months endedMarch 31, 2018 and 2017.

Capital Lease

During 2016, the Company entered into a 49-year master lease at 991 Madison Avenue, which is accounted for as a capital lease. During each of the three months endedMarch 31, 2018 and 2017, payments for this lease totaled $0.6 million. The lease was initially valued at $76.6 million, which represents the total discounted payments to be made under the lease. The property under the capital lease is included in Note 2.

Lease Obligations

The scheduled future minimum (i) rental revenues from rental properties under the terms of all non-cancelable tenant leases, assuming no new or renegotiated leases or option extensions for such premises and (ii) rental payments under the terms of all non-cancelable operating and capital leases in which the Company is the lessee, principally for office space and ground leases, as of March 31, 2018, are summarized as follows (in thousands):

Year Ending December 31,	Minimum Rental Revenues		Minimum Rental Payments
2018 (Remainder)	$	125,069	$	4,546
2019	169,873		4,565
2020	155,238		4,256
2021	135,874		4,364
2022	116,972		4,400
Thereafter	527,122		183,911
Total	$	1,230,148	$	206,042

A ground lease expiring during 2078 provides the Company with an option to purchase the underlying land during 2031. If the Company does not exercise the option, the rents that will be due are based on future values and as such are not determinable at this time. Accordingly, the above table does not include rents for this lease beyond 2031.

During the three months endedMarch 31, 2018 and 2017, no single tenant collectively comprised more than 10% of the Company’s consolidated total revenues.

12. Segment Reporting

The Company has three reportable segments: Core Portfolio, Funds and Structured Financing. The Company’s Core Portfolio consists primarily of high-quality retail properties located primarily in high-barrier-to-entry, densely-populated metropolitan areas with a long-term investment horizon. The Company’s Funds hold primarily retail real estate in which the Company co-invests with high-quality institutional investors. The Company’s Structured Financing segment consists of earnings and expenses related to notes and mortgages receivable which are held within the Core Portfolio or the Funds (Note 3). Fees earned by the Company as the general partner or managing member of the Funds are eliminated in the Company’s consolidated financial statements and are not presented in the Company’s segments.

13. Share Incentive and Other Compensation

Share Incentive Plan

The Second Amended and Restated 2006 Incentive Plan (the “Share Incentive Plan”) authorizes the Company to issue options, Restricted Shares, LTIP Units and other securities (collectively “Awards”) to, among others, the Company’s officers, trustees and employees. At March 31, 2018 a total of 1,223,815 shares remained available to be issued under the Share Incentive Plan.

Restricted Shares and LTIP Units

During the three months endedMarch 31, 2018, the Company issued 381,821 LTIP Units and 5,768 Restricted Share Units to employees of the Company pursuant to the Share Incentive Plan. These awards were measured at their fair value on the grant date, based on a valuation provided by an independent third-party appraiser incorporating the following factors:

• A portion of these annual equity award is granted in performance-based Restricted Share Units or LTIP Units that may be earned based on the Company’s attainment of specified relative total shareholder returns (“Relative TSR”) hurdles.

• In the event the Relative TSR percentile falls between the 25th percentile and the 50th percentile, Relative TSR vesting percentage is determined using a straight line linear interpolation between 50% and 100% and in the event that the Relative TSR percentile falls between the 50th percentile and 75th percentile, the Relative TSR vesting percentage is determined using a straight line linear interpolation between 100% and 200%.

• Two-thirds (2/3) of the performance-based LTIP Units will vest based on the Company’s total shareholder return (“TSR”) for the three-year forward-looking performance period ending December 31, 2020 relative to the constituents of the SNL U.S. REIT Retail Shopping Center Index and one-third (1/3) on the Company’s TSR for the three-year forward-looking performance period as compared to the constituents of the SNL U.S. REIT Retail Index (both on a non-weighted basis).

• If the Company’s performance fails to achieve the aforementioned hurdles at the culmination of the three-year performance period, all performance-based shares will be forfeited. Any earned performance-based shares vest 60% at the end of the performance period, with the remaining 40% of shares vesting ratably over the next two years.

The total value of the above Restricted Share Units and LTIP Units as of the grant date was $10.6 million. Total long-term incentive compensation expense, including the expense related to the Share Incentive Plan, was $2.2 million and $1.9 million for the three months endedMarch 31, 2018 and 2017, respectively and is recorded in General and Administrative on the Consolidated Statements of Income.

In addition, members of the Board of Trustees (the “Board”) have been issued shares and units under the Share Incentive Plan. During 2017, the Company issued 11,814 Restricted Shares and 11,105 LTIP Units to Trustees of the Company in connection with Trustee fees. Vesting with respect to 3,864 of the Restricted Shares and 5,805 of the LTIP Units will be on the first anniversary of the date of issuance and 7,950 of the Restricted Shares and 5,300 of the LTIP Units vest over three years with 33% vesting on each of the next three anniversaries of the issuance date. The Restricted Shares do not carry voting rights or other rights of Common Shares until vesting and may not be transferred, assigned or pledged until the recipients have a vested non-forfeitable right to such shares. Dividends are not paid currently on unvested Restricted Shares, but are paid cumulatively from the issuance date through the applicable vesting date of such Restricted Shares. Total trustee fee expense, including the expense related to the Share Incentive Plan, was $0.3 million for each of the three months endedMarch 31, 2018 and 2017, respectively.

In 2009, the Company adopted the Long Term Investment Alignment Program (the “Program”) pursuant to which the Company may grant awards to employees, entitling them to receive up to 25% of any potential future payments of Promote to the Operating Partnership from Funds III and IV. The Company has granted such awards to employees representing 25% of the potential Promote payments from Fund III to the Operating Partnership and 22.8% of the potential Promote payments from Fund IV to the Operating Partnership. Payments to senior executives under the Program require further Board approval at the time any potential payments are due pursuant to these grants. Compensation relating to these awards will be recognized in each reporting period in which Board approval is granted.

As payments to other employees are not subject to further Board approval, compensation relating to these awards will be recorded based on the estimated fair value at each reporting period in accordance with ASC Topic 718, Compensation– Stock Compensation. The awards in connection with Fund IV were determined to have no intrinsic value as of March 31, 2018.

As of March 31, 2018, there was $21.0 million of total unrecognized compensation cost related to unvested share-based compensation arrangements granted under the Share Incentive Plan. That cost is expected to be recognized over a weighted-average period of 1.9 years. The total fair value of Restricted Shares that vested for each of the three months endedMarch 31, 2018 and the year ended December 31, 2017, was $0.7 million. The total fair value of LTIP Units that vested during the three months endedMarch 31, 2018 and the year ended December 31, 2017, was $8.8 million and $7.3 million, respectively.

Other Plans

On a combined basis, the Company incurred a total of $0.1 million related to the following employee benefit plans for each of the three months endedMarch 31, 2018 and 2017, respectively:

Employee Share Purchase Plan

The Acadia Realty Trust Employee Share Purchase Plan (the “Purchase Plan”), allows eligible employees of the Company to purchase Common Shares through payroll deductions. The Purchase Plan provides for employees to purchase Common Shares on a quarterly basis at a 15% discount to the closing price of the Company’s Common Shares on either the first day or the last day of the quarter, whichever is lower. A participant may not purchase more the $25,000 in Common Shares per year. Compensation expense will be recognized by the Company to the extent of the above discount to the closing price of the Common Shares with respect to the applicable quarter. A total of 943 and 841 Common Shares were purchased by employees under the Purchase Plan., for each of the three months endedMarch 31, 2018 and 2017, respectively.

Deferred Share Plan

During May of 2006, the Company adopted a Trustee Deferral and Distribution Election, under which the participating Trustees earn deferred compensation.

Employee 401(k) Plan

The Company maintains a 401(k) plan for employees under which the Company currently matches 50% of a plan participant’s contribution up to 6% of the employee’s annual salary. A plan participant may contribute up to a maximum of 15% of their compensation, up to $18,000, for the year ending December 31, 2018.

14. Earnings Per Common Share

Basic earnings per Common Share is computed by dividing net income attributable to Common Shareholders by the weighted average Common Shares outstanding (Note 10, Note 15). During the periods presented, the Company had unvested LTIP Units which provide for non-forfeitable rights to dividend equivalent payments. Accordingly, these unvested LTIP Units are considered participating securities and are included in the computation of basic earnings per Common Share pursuant to the two-class method.

Diluted earnings per Common Share reflects the potential dilution of the conversion of obligations and the assumed exercises of securities including the effects of restricted share units (“Restricted Share Units”) issued under the Company’s Share Incentive Plans (Note 13). The effect of such shares is excluded from the calculation of earnings per share when anti-dilutive as indicated in the table below.

The effect of the conversion of Common OP Units is not reflected in the computation of basic and diluted earnings per share, as they are exchangeable for Common Shares on a one-for-one basis. The income allocable to such units is allocated on this same basis and reflected as noncontrolling interests in the accompanying consolidated financial statements. As such, the assumed conversion of these units would have no net impact on the determination of diluted earnings per share.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

OVERVIEW

As of March 31, 2018, there were 175 properties, which we own or have an ownership interest in, within our Core Portfolio and Funds. Our Core Portfolio consists of those properties either 100% owned, or partially owned through joint venture interests by the Operating Partnership, or subsidiaries thereof, not including those properties owned through our Funds. These properties primarily consist of street and urban retail, and dense suburban shopping centers. A summary of our wholly-owned and partially-owned retail properties and their physical occupancies at March 31, 2018 is as follows:

	Number of Properties		Operating Properties
	Development	Operating	GLA	Occupancy
Core Portfolio:
Chicago Metro	2	33	697,139	91.0	%

The majority of our operating income is derived from rental revenues from operating properties, including expense recoveries from tenants, offset by operating and overhead expenses. As our RCP Venture invests in operating companies, the Operating Partnership invests through a taxable REIT subsidiary (“TRS”).

Our primary business objective is to acquire and manage commercial retail properties that will provide cash for distributions to shareholders while also creating the potential for capital appreciation to enhance investor returns. We focus on the following fundamentals to achieve this objective:

• Own and operate a Core Portfolio of high-quality retail properties located primarily in high-barrier-to-entry, densely-populated metropolitan areas and create value through accretive development and re-tenanting activities coupled with the acquisition of high-quality assets that have the long-term potential to outperform the asset class as part of our Core asset recycling and acquisition initiative.

• Generate additional external growth through an opportunistic yet disciplined acquisition program within our Funds. We target transactions with high inherent opportunity for the creation of additional value through:

◦ value-add investments in street retail properties, located in established and “next generation” submarkets, with re-tenanting or repositioning opportunities,

41

◦ opportunistic acquisitions of well-located real-estate anchored by distressed retailers, and

◦ other opportunistic acquisitions which may include high-yield acquisitions and purchases of distressed debt.

Some of these investments historically have also included, and may in the future include, joint ventures with private equity investors for the purpose of making investments in operating retailers with significant embedded value in their real estate assets.

• Maintain a strong and flexible balance sheet through conservative financial practices while ensuring access to sufficient capital to fund future growth.

SIGNIFICANT DEVELOPMENTS DURING THE THREE MONTHS ENDED MARCH 31, 2018

Investments

During the three months endedMarch 31, 2018, within our Fund portfolio we invested in one new property as follows (Note 2):

• On February 21, 2018, Fund V acquired a consolidated suburban shopping center in Trussville, Alabama for $45.2 million referred to as “Trussville.”

In addition, we converted a portion of an existing note receivable (Note 3) into an interest in the underlying real estate collateral as follows:

• On March 28, 2018, we exchanged a total of $22.0 million of our Brandywine Note Receivable plus accrued interest of $0.3 million for an incremental 14.11% undivided interest in Town Center (Note 4).

Dispositions of Real Estate

During the three months endedMarch 31, 2018, within our Funds we sold two properties for an aggregate sales price of $8.0 million as follows (Note 4):

• On January 18, 2018, Fund IV sold two unconsolidated properties for aggregate proceeds of $8.0 million and recognized a loss of $0.4 million at the property level, of which both Fund IV and our pro-rata share was $0.

Financings

During the three months endedMarch 31, 2018, we obtained aggregate new financing of $89.8 million including (Note 7):

• We obtained an aggregate of $39.8 million in financings with two new non-recourse mortgages for Fund V.

• We obtained a new $500.0 million Core Credit Facility comprised of a $150.0 million senior unsecured revolving credit facility and a $350.0 million senior unsecured term loan and refinanced our existing $300.0 million credit facility (comprised of the $150.0 million Core unsecured revolving line of credit and the $150.0 million term loan) and $150.0 million in term loans.

We utilized proceeds from the new term loan to repay one Core mortgage in the amount of $40.4 million.

Structured Financing

During the three months endedMarch 31, 2018 (Note 3) we entered into the following structured financing transactions:

• On March 28, 2018, we exchanged a total of $22.0 million of our Core Brandywine Note Receivable plus accrued interest of $0.3 million for an incremental 14.11% undivided interest in Town Center (Note 4).

• On January 24, 2018, we received full payment on a $26.0 million Core note receivable plus $0.2 million interest thereon.

• On March 16, 2018, we funded an additional $2.8 million on an existing Core $15.0 million note receivable.

42

Share Repurchase Plan

In February 2018, our board of trustees elected to terminate the existing repurchase program and authorized a new common share repurchase program under which we may repurchase, from time to time, up to a maximum of $200.0 million of our common shares (Note 10). Through March 31, 2018, the Company repurchased 1,304,194 shares for $32.0 million. Additional shares were repurchased subsequent to March 31, 2018 as discussed in Note 15.

RESULTS OF OPERATIONS

Core Portfolio

The results of operations for our Core Portfolio segment are depicted in the table above under the headings labeled “Core.” Segment net income attributable to Acadia for our Core Portfolio increased by $2.0 million for the three months ended March 31, 2018 compared to the prior year period as a result of the changes as further described below.

Revenues from our Core Portfolio decreased by$2.8 millionfor thethree months ended March 31, 2018compared to the prior year period due primarily to real estate tax income of $1.8 million in 2017as a result of a real estate tax reassessment for certain properties in 2017 as well as a decline in occupancy due to tenant bankruptcies in 2018.

Property operating, other operating expenses and real estate taxes for our Core Portfolio decreased by$2.0 millionfor thethree months ended March 31, 2018compared to the prior year period primarily duean increased real estate tax reassessment in 2017 for certain properties of $2.4 million.

43

Funds

The results of operations for our Funds segment are depicted in the table above under the headings labeled “Funds.” Segment net income attributable to Acadia for the Funds decreased by $4.6 million for the three months ended March 31, 2018 compared to the prior year period as a result of the changes described below.

Revenues from the Funds increased by$3.9 millionfor thethree months ended March 31, 2018compared to the prior year period primarily due to a $6.4 million increase from Fund property acquisitions in 2017 and 2018 anda $1.7 million increase from development projects being placed in service during 2017. These increases were offset by a decrease of $4.3 million related to property sales in 2017.

Depreciation and amortization for the Funds increased by$5.0 millionfor thethree months ended March 31, 2018compared to the prior year period primarily due to a $4.1 million increase from Fund property acquisitions in 2017 and 2018 andas well as $1.8 million from development projects being placed in service during 2017. These increases were offset by a decrease of $1.5 million for property sales in 2017.

Property operating, other operating expenses and real estate taxes for the Funds increased by$2.3 millionfor thethree months ended March 31, 2018compared to the prior year period primarily due to a $2.6 millionincrease from the development projects being placed in service during 2017and a $1.0 million increase from Fund property acquisitions in 2017 and 2018. These increases were offset by a decrease of $1.3 million for property sales in 2017.

Equity in earnings of unconsolidated affiliates for the Funds decreased by $11.8 million for the three months ended March 31, 2018 compared to the prior year period primarily due to the Fund’s proportionate share of $11.5 million in aggregate gains from the sales of Arundel Plaza and 2819 Kennedy Boulevard during the prior year period.

Interest expense for the Funds increased $5.1 million for the three months ended March 31, 2018 compared to the prior year period due to $3.7 million less interest capitalized during 2018 and a $1.3 million increase related to higher average outstanding rates and borrowings in 2018.

Net income attributable to noncontrolling interests in the Funds decreased by $15.6 million for the three months ended March 31, 2018 compared to the prior year period due to the noncontrolling interests’ share of the variances discussed above.

Structured Financing

The results of operations for our Structured Financing segment are depicted in the table above under the headings labeled “SF.” Net income for Structured Financing decreased by $5.3 million for the three months ended March 31, 2018 compared to the prior year period primarily due to the recognition of additional interest of $2.5 million during the prior year period on the repayment of a note (Note 3) along with, $1.8 million from the conversion of a portion of a note receivable into increased ownership in the real estate (Note 4) and loan payoffs during 2017 and 2018.

Unallocated

The Company does not allocate general and administrative expense and income taxes to its reportable segments. These unallocated amounts are depicted in the table above under the headings labeled“Total.”

SUPPLEMENTAL FINANCIAL MEASURES

Net Property Operating Income

The following discussion of net property operating income (“NOI”) and rent spreads on new and renewal leases includes the activity from both our consolidated and our pro-rata share of unconsolidated properties within our Core Portfolio. Our Funds invest primarily in properties that typically require significant leasing and development. Given that the Funds are finite-life investment vehicles, these properties are sold following stabilization. For these reasons, we believe NOI and rent spreads are not meaningful measures for our Fund investments.

NOI represents property revenues less property expenses. We consider NOI and rent spreads on new and renewal leases for our Core Portfolio to be appropriate supplemental disclosures of portfolio operating performance due to their widespread acceptance and use within the REIT investor and analyst communities. NOI and rent spreads on new and renewal leases are presented to assist investors in analyzing our property performance, however, our method of calculating these may be different from methods used by other REITs and, accordingly, may not be comparable to such other REITs.

A reconciliation of consolidated operating income to net operating income - Core Portfolio follows (in thousands):

Rent Spreads on Core Portfolio New and Renewal Leases

The following table summarizes rent spreads on both a cash basis and straight-line basis for new and renewal leases based on leases executed within our Core Portfolio for the three months endedMarch 31, 2018. Cash basis represents a comparison of rent most recently paid on the previous lease as compared to the initial rent paid on the new lease. Straight-line basis represents a comparison of rents as adjusted for contractual escalations, abated rent and lease incentives for the same comparable leases.

(a) The average cost per square foot includes tenant improvement costs, leasing commissions and tenant allowances.

Funds from Operations

We consider funds from operations (“FFO”) as defined by the National Association of Real Estate Investment Trusts (“NAREIT”) to be an appropriate supplemental disclosure of operating performance for an equity REIT due to its widespread acceptance and use within the REIT and analyst communities. FFO is presented to assist investors in analyzing our performance. It is helpful as it excludes various items included in net income that are not indicative of the operating performance, such as gains (losses) from sales of depreciated property, depreciation and amortization, and impairment of depreciable real estate. Our method of calculating FFO may be different from methods used by other REITs and, accordingly, may not be comparable to such other REITs. FFO does not represent cash generated from operations as defined by generally accepted accounting principles (“GAAP”) and is not indicative of cash available to fund all cash needs, including distributions. It should not be considered as an alternative to net income for the purpose of evaluating our performance or to cash flows as a measure of liquidity. Consistent with the NAREIT definition, we define FFO as net income (computed in accordance with GAAP), excluding gains (losses) from sales of depreciated property and impairment of depreciable real estate, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. A reconciliation of net income attributable to Acadia to FFO follows (dollars in thousands, except per share amounts):

LIQUIDITY AND CAPITAL RESOURCES

Uses of Liquidity and Cash Requirements

Our principal uses of liquidity are (i) distributions to our shareholders and OP unit holders, (ii) investments which include the funding of our capital committed to the Funds and property acquisitions and development/re-tenanting activities within our Core Portfolio, (iii) distributions to our Fund investors, (iv) debt service and loan repayments and (v) share repurchases.

Distributions

In order to qualify as a REIT for Federal income tax purposes, we must currently distribute at least 90% of our taxable income to our shareholders. During the three months endedMarch 31, 2018, we paid dividends and distributions on our Common Shares, Common OP Units and Preferred OP Units totaling $22.6 million.

Investments in Real Estate

As of March 31, 2018, our consolidated outstanding mortgage and notes payable aggregated $1,467.7 million, excluding unamortized premium of $0.8 million and unamortized loan costs of $13.3 million, and were collateralized by 43 properties and related tenant leases. Interest rates on our outstanding indebtedness ranged from 1.00% to 6.00% with maturities that ranged from April 15, 2018, to August 23, 2042. Taking into consideration $529.6 million of notional principal under variable to fixed-rate swap agreements currently in effect, $915.5 million of the portfolio debt, or 62.4%, was fixed at a 3.77% weighted-average interest rate and $552.2 million, or 37.6% was floating at a 3.71% weighted average interest rate as of March 31, 2018. Our variable-rate debt includes $143.8 million of debt subject to interest rate caps.

There is $47.8 million of debt maturing in 2018 at a weighted-average interest rate of 5.44%; there is $4.6 million of scheduled principal amortization due in 2018; and our share of scheduled remaining 2018 principal payments and maturities on our unconsolidated debt was $7.6 million at March 31, 2018. In addition, $208.0 million of our total consolidated debt and $1.0 million of our pro-rata share of unconsolidated debt will come due in 2019. As it relates to the maturing debt in 2018 and 2019, we may not have sufficient cash on hand to repay such indebtedness, and, therefore, we expect to refinance at least a portion of this indebtedness or select other alternatives based on market conditions as these loans mature; however, there can be no assurance that we will be able to obtain financing at acceptable terms.

A mortgage loan in the Company’s Core Portfolio for $26.3 million was in default at March 31, 2018 and December 31, 2017 (Note 7). In April 2017, the lender on this mortgage initiated a lawsuit against the Company for the full balance of the principal, accrued interest as well as penalties and fees aggregating approximately $32.9 million. The Company’s management believes that the mortgage is not recourse to the Company and that the suit is without merit.

Share Repurchases

The Company repurchased $32.0 million, or 1,304,194 shares, pursuant to its new share repurchase program during the three months endedMarch 31, 2018. During April 2018, the Company repurchased additional shares under this program as discussed in Note 15.

Sources of Liquidity

Our primary sources of capital for funding our liquidity needs include (i) the issuance of both public equity and OP Units, (ii) the issuance of both secured and unsecured debt, (iii) unfunded capital commitments from noncontrolling interests within our Funds, (iv) future sales of existing properties, (v) repayments of structured financing investments, and (vi) cash on hand and future cash flow from operating activities. Our cash on hand in our consolidated subsidiaries at March 31, 2018 totaled $39.3 million. Our remaining sources of liquidity are described further below.

Issuance of Equity

We have an at-the-market (“ATM”) equity issuance program which provides us an efficient and low-cost vehicle for raising public equity to fund our capital needs. Through this program, we have been able to effectively “match-fund” the required equity for our Core Portfolio and Fund acquisitions through the issuance of Common Shares over extended periods employing a price averaging strategy. In addition, from time to time, we have issued and intend to continue to issue, equity in follow-on offerings separate from our ATM program. Net proceeds raised through our ATM program and follow-on offerings are primarily used for acquisitions, both for our Core Portfolio and our pro-rata share of Fund acquisitions, and for general corporate purposes. There were no issuances of equity under the ATM program during the three months endedMarch 31, 2018.

Fund Capital

During the three months endedMarch 31, 2018, there were no noncontrolling interest capital contributions to our Funds. At March 31, 2018, unfunded capital commitments from noncontrolling interests within our Funds III, IV and V were $29.1 million, $90.2 million and $378.9 million, respectively.

Asset Sales

As previously discussed, during the three months endedMarch 31, 2018, within our Fund portfolio we sold two unconsolidated properties for an aggregate sales price of $8.0 million for which Fund IV received $4.3 million net of funds used to repay the associated debt (Note 2, Note 4).

Structured Financing Repayments

During the three months endedMarch 31, 2018, we received total collections on a note receivable of $26.0 million (Note 3). There are no scheduled principal collections for the remainder of 2018.

Financing and Debt

As of March 31, 2018, we had $189.2 million of additional capacity under existing revolving debt facilities. In addition, at that date within our Core and Fund portfolios, we had 71 unleveraged consolidated properties with an aggregate carrying value of approximately $1.6 billion and 17 unleveraged unconsolidated properties for which our share of the carrying value was $142.4 million, although there can be no assurance that we would be able to obtain financing for these properties at favorable terms, if at all.

HISTORICAL CASH FLOW

The following table compares the historical cash flow for the three months endedMarch 31, 2018 with the cash flow for the three months endedMarch 31, 2017 (in millions):

	Three Months Ended March 31,
	2018			2017			Variance
Net cash provided by operating activities	$	22.9		$	24.5		$	(1.6	)
Net cash used in investing activities	(26.3		)	(39.3		)	13.0
Net cash used in financing activities	(30.5		)	(8.2		)	(22.3		)
Decrease in cash and restricted cash	$	(33.9	)	$	(23.0	)	$	(10.9	)

Operating Activities

Our operating activities provided $1.6 million less cash during the three months endedMarch 31, 2018 as compared to the three months endedMarch 31, 2017, primarily due to a reduction in the current year in interest income following the monetization of structured finance investments, partially offset by cash flows from the 2017 and 2018 Fund acquisitions.

Investing Activities

During the three months endedMarch 31, 2018 as compared to the three months endedMarch 31, 2017, our investing activities used $13.0 million less cash, primarily due to (i) $26.0 million more cash received from repayments of notes receivable, (ii) $8.9 million less cash used for development and property improvement costs, (iii) $13.5 million more cash received from return of capital from unconsolidated affiliates, and (iv) $1.3 million less cash used for investments and advances to unconsolidated investments. These items were partially offset by (i) $25.1 million less cash received from disposition of properties, including unconsolidated affiliates, (ii) $9.7 million more cash used for the acquisition of real estate, and (iii) $2.8 million more cash used for the issuance of notes receivable.

Financing Activities

Our financing activities used $22.3 million more cash during the three months endedMarch 31, 2018 as compared to the three months endedMarch 31, 2017, primarily from (i) $32.0 million more cash used from the repurchase of Common Shares, and (ii) a decrease in cash of $20.3 million from capital contributions from noncontrolling interests. These items were partially offset by (i) an increase of $15.6 million of cash provided from net borrowings, (ii) a decrease of $11.7 million in cash paid for dividends to common shareholders, and (iii) a decrease of $3.8 million in cash distributions to noncontrolling interests.

CONTRACTUAL OBLIGATIONS

The following table summarizes: (i) principal and interest obligations under mortgage and other notes, (ii) rents due under non-cancelable operating and capital leases, which includes ground leases at seven of our properties and the lease for our corporate office and (iii) construction commitments as of March 31, 2018 (in millions):

	Payments Due by Period
Contractual Obligations	Total		Less than 1 Year		1 to 3 Years		3 to 5 Years		More than 5 Years
Principal obligations on debt	$	1,467.7	$	71.4	$	769.4	$	457.4	$	169.5
Interest obligations on debt	229.3		62.9		91.1		48.3		27.0
Lease obligations (a)	206.0		4.5		8.8		8.8		183.9
Construction commitments (b)	87.1		87.1		—		—		—
Total	$	1,990.1	$	225.9	$	869.3	$	514.5	$	380.4

__________

(a) A ground lease expiring during 2078 provides the Company with an option to purchase the underlying land during 2031. If we do not exercise the option, the rents that will be due are based on future values and as such are not determinable at this time. Accordingly, the above table does not include rents for this lease beyond 2031.

(b) In conjunction with the development of our Core Portfolio and Fund properties, we have entered into construction commitments with general contractors. We intend to fund these requirements with existing liquidity.

OFF-BALANCE SHEET ARRANGEMENTS

We have the following investments made through joint ventures for the purpose of investing in operating properties. We account for these investments using the equity method of accounting. As such, our financial statements reflect our investment and our share of income and loss from, but not the individual assets and liabilities, of these joint ventures.

See Note 4 in the Notes to Consolidated Financial Statements, for a discussion of our unconsolidated investments. The Operating Partnership’s pro-rata share of unconsolidated non-recourse debt related to those investments is as follows (dollars in millions):

	Operating Partnership Ownership Percentage		Operating Partnership Pro-rata Share of Mortgage Debt
Investment					Interest Rate at March 31, 2018		Maturity Date
230/240 W. Broughton	11.6	%	$	1.2	4.67	%	May 2018
Promenade at Manassas	22.8	%	5.7		3.37	%	November 2018

Georgetown Portfolio	50.0	%	8.4		4.72	%	December 2027
Total			$	163.3

(a) Our unconsolidated affiliate is a party to an interest rate LIBOR swap with a notional value of $20.3 million, which effectively fixes the interest rate at 3.49% and matures in June 2023.

CRITICAL ACCOUNTING POLICIES

Management’s discussion and analysis of financial condition and results of operations is based upon our Consolidated Financial Statements, which have been prepared in accordance with U.S. GAAP. The preparation of these Consolidated Financial Statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. We base our estimates on historical experience and assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe there have been no material changes to the items that we disclosed as our critical accounting policies under Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in our 2017 Form 10-K.

Recently Issued Accounting Pronouncements

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Information as of March 31, 2018

Our primary market risk exposure is to changes in interest rates related to our mortgage and other debt. See Note 7 in the Notes to Consolidated Financial Statements, for certain quantitative details related to our mortgage and other debt.

Currently, we manage our exposure to fluctuations in interest rates primarily through the use of fixed-rate debt and interest rate swap and cap agreements. As of March 31, 2018, we had total mortgage and other notes payable of $1,467.7 million, excluding the unamortized premium of $0.8 million and unamortized loan costs of $13.3 million, of which $915.5 million, or 62.4% was fixed-rate, inclusive of debt with rates fixed through the use of derivative financial instruments, and $552.2 million, or 37.6%, was variable-rate based upon LIBOR or Prime rates plus certain spreads. As of March 31, 2018, we were party to 26 interest rate swap and four interest rate cap agreements to hedge our exposure to changes in interest rates with respect to $529.6 million and $143.8 million of LIBOR-based variable-rate debt, respectively.

The following table sets forth information as of March 31, 2018 concerning our long-term debt obligations, including principal cash flows by scheduled maturity and weighted average interest rates of maturing amounts (dollars in millions):

Core Consolidated Mortgage and Other Debt

Year	Scheduled Amortization		Maturities		Total		Weighted-Average Interest Rate

52

In 2018, $52.4 million of our total consolidated debt and $7.6 million of our pro-rata share of unconsolidated outstanding debt will become due. In addition, $208.0 million of our total consolidated debt and $1.0 million of our pro-rata share of unconsolidated debt will become due in 2019. As we intend on refinancing some or all of such debt at the then-existing market interest rates, which may be greater than the current interest rate, our interest expense would increase by approximately $2.6 million annually if the interest rate on the refinanced debt increased by 100 basis points. After giving effect to noncontrolling interests, our share of this increase would be $0.6 million. Interest expense on our variable-rate debt of $552.2 million, net of variable to fixed-rate swap agreements currently in effect, as of March 31, 2018, would increase $5.4 million if LIBOR increased by 100 basis points. After giving effect to noncontrolling interests, our share of this increase would be $1.1 million. We may seek additional variable-rate financing if and when pricing and other commercial and financial terms warrant. As such, we would consider hedging against the interest rate risk related to such additional variable-rate debt through interest rate swaps and protection agreements, or other means.

Based on our outstanding debt balances as of March 31, 2018, the fair value of our total consolidated outstanding debt would decrease by approximately $15.0 million if interest rates increase by 1%. Conversely, if interest rates decrease by 1%, the fair value of our total outstanding debt would increase by approximately $16.3 million.

As of March 31, 2018, and December 31, 2017, we had consolidated notes receivable of $109.0 million and $153.8 million, respectively. We determined the estimated fair value of our notes receivable by discounting future cash receipts utilizing a discount rate equivalent to the rate at which similar notes receivable would be originated under conditions then existing.

Based on our outstanding notes receivable balances as of March 31, 2018, the fair value of our total outstanding notes receivable would decrease by approximately $1.7 million if interest rates increase by 1%. Conversely, if interest rates decrease by 1%, the fair value of our total outstanding notes receivable would increase by approximately $1.8 million.

Summarized Information as of December 31, 2017

As of December 31, 2017, we had total mortgage and other notes payable of $1,438.4 million, excluding the unamortized premium of $0.9 million and unamortized loan costs of $14.8 million, of which $899.7 million, or 62.5% was fixed-rate, inclusive of interest rate swaps, and $538.7 million, or 37.5%, was variable-rate based upon LIBOR plus certain spreads. As of December 31, 2017, we were party to 27 interest rate swap and four interest rate cap agreements to hedge our exposure to changes in interest rates with respect to $504.0 million and $141.1 million of LIBOR-based variable-rate debt, respectively.

Interest expense on our variable-rate debt of $538.7 million as of December 31, 2017, would have increased $5.4 million if LIBOR increased by 100 basis points. Based on our outstanding debt balances as of December 31, 2017, the fair value of our total outstanding debt would have decreased by approximately $15.9 million if interest rates increased by 1%. Conversely, if interest rates decreased by 1%, the fair value of our total outstanding debt would have increased by approximately $17.3 million.

Changes in Market Risk Exposures from December 31, 2017 to March 31, 2018

Our interest rate risk exposure from December 31, 2017, to March 31, 2018, has increased on an absolute basis, as the $538.7 million of variable-rate debt as of December 31, 2017, has increased to $552.2 million as of March 31, 2018. As a percentage of our overall debt, our interest rate risk exposure has decreased as our variable-rate debt accounted for 37.5% of our consolidated debt as of December 31, 2017, and decreased to 37.6% as of March 31, 2018.

ITEM 4. CONTROLS AND PROCEDURES.

Disclosure Controls and Procedures

Our disclosure controls and procedures include internal controls and other procedures designed to provide reasonable assurance that information required to be disclosed in this and other reports filed under the Exchange Act, is recorded, processed, summarized, and reported within the required time periods specified in the SEC’s rules and forms; and that such information is accumulated and communicated to management, including our chief executive officer and chief financial officer, to allow timely decisions regarding required disclosures. It should be noted that no system of controls can provide complete assurance of achieving a company’s objectives and that future events may impact the effectiveness of a system of controls. Our chief executive officer and chief financial officer, after conducting an evaluation, together with members of our management, of the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2018, have concluded that our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) were effective as of March 31, 2018, at a reasonable level of assurance.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

We are involved in various matters of litigation arising in the normal course of business. While we are unable to predict with certainty the outcome of any particular matter, Management is of the opinion that, when such litigation is resolved, our resulting exposure to loss contingencies, if any, will not have a significant effect on our consolidated financial position, results of operations, or liquidity.

ITEM 1A. RISK FACTORS.

The most significant risk factors applicable to us are described in Item 1A. of our 2017 Form 10-K. There have been no material changes to those previously-disclosed risk factors.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS.

As previously disclosed in the Company’s Annual Report on 10-K, on February 20, 2018, the Company revised its share repurchase program. The new share repurchase program authorizes management, at its discretion, to repurchase up to $200.0 million of its outstanding Common Shares. The program may be discontinued or extended at any time. The Company repurchased shares during the three months endedMarch 31, 2018 as follows:

Period	(a) Total Number of Shares (or Units) Purchased	(b) Average Price Paid per Share (or Unit)		(c) Total Number of Shares (or Units) Purchased as Part of Publicly Announced Plans or Programs	(d) Maximum Number (or Approximated Dollar Value) of Shares (or Units) that May Yet Be Purchased Under the Plans or Programs

Organization, Basis of Presentation and Summary of Significant Accounting Policies

Organization

Acadia Realty Trust and subsidiaries (collectively, the “Company”) is a fully-integrated equity real estate investment trust (“REIT”) focused on the ownership, acquisition, development, and management of retail properties located primarily in high-barrier-to-entry, supply-constrained, densely-populated metropolitan areas in the United States.

All of the Company’s assets are held by, and all of its operations are conducted through, Acadia Realty Limited Partnership (the “Operating Partnership”) and entities in which the Operating Partnership owns an interest. As of March 31, 2018 and December 31, 2017, the Company controlled approximately 94% and 95%, respectively, of the Operating Partnership as the sole general partner and is entitled to share, in proportion to its percentage interest, in the cash distributions and profits and losses of the Operating Partnership. The limited partners primarily represent entities or individuals that contributed their interests in certain properties or entities to the Operating Partnership in exchange for common or preferred units of limited partnership interest (“Common OP Units” or “Preferred OP Units”) and employees who have been awarded restricted Common OP Units (“LTIP Units”) as long-term incentive compensation (Note 13). Limited partners holding Common OP and LTIP Units are generally entitled to exchange their units on a one-for-one basis for common shares of beneficial interest of the Company (“Common Shares”). This structure is referred to as an umbrella partnership REIT or “UPREIT.”

As of March 31, 2018, the Company has ownership interests in 118 properties within its core portfolio, which consist of those properties either 100% owned, or partially owned through joint venture interests, by the Operating Partnership, or subsidiaries thereof, not including those properties owned through its funds (“Core Portfolio”). The Company also has ownership interests in 57 properties within its opportunity funds, Acadia Strategic Opportunity Fund II, LLC (“Fund II”), Acadia Strategic Opportunity Fund III LLC (“Fund III”), Acadia Strategic Opportunity Fund IV LLC (“Fund IV”), and Acadia Strategic Opportunity Fund V LLC (“Fund V”). Acadia Strategic Opportunity Fund I, LP (“Fund I,” together with Funds II, III, IV, and V, the “Funds”) was liquidated in 2015. The 175 Core Portfolio and Fund properties primarily consist of street and urban retail, and suburban shopping centers. In addition, the Company, together with the investors in the Funds, invest in operating companies through Acadia Mervyn Investors I, LLC (“Mervyns I,” which was liquidated in 2018), Acadia Mervyn Investors II, LLC (“Mervyns II”) and Fund II, all on a non-recourse basis. The Company consolidates the Funds as it has (i) the power to direct the activities that most significantly impact the Funds’ economic performance, (ii) is obligated to absorb the Funds’ losses and (iii) has the right to receive benefits from the Funds that could potentially be significant.

The Operating Partnership is the sole general partner or managing member of the Funds and Mervyns I and II and earns fees or priority distributions for asset management, property management, construction, development, leasing, and legal services. Cash flows from the Funds and Mervyns I and II are distributed pro-rata to their respective partners and members (including the Operating Partnership) until each receives a certain cumulative return (“Preferred Return”) and the return of all capital contributions. Thereafter, remaining cash flow is distributed 20% to the Operating Partnership (“Promote”) and 80% to the partners or members (including the Operating Partnership). All transactions between the Funds and the Operating Partnership have been eliminated in consolidation.

The following table summarizes the general terms and Operating Partnership’s equity interests in the Funds and Mervyns II (dollars in millions):

Entity	Formation Date	Operating Partnership Share of Capital	Capital Called as of March 31, 2018		Unfunded Commitment		Equity Interest Held By Operating Partnership (a)	Preferred Return	Total Distributions as of March 31, 2018 (b)
Fund II and Mervyns II	6/2004	28.33%	$	347.1	$	—	28.33%	8%	$	131.6
Fund III	5/2007	24.54%	411.5		38.5		24.54%	6%	551.9
Fund IV	5/2012	23.12%	412.7		117.3		23.12%	6%	131.5
Fund V	8/2016	20.10%	45.8		474.2		20.10%	6%	—

__________

(a) Amount represents the current economic ownership at March 31, 2018, which could differ from the stated legal ownership based upon the cumulative preferred returns of the respective fund.

(b) Represents the total for the Funds, including the Operating Partnership and noncontrolling interests’ shares.

Basis of Presentation

Segments

At March 31, 2018, the Company had three reportable operating segments: Core Portfolio, Funds and Structured Financing. The Company’s chief operating decision maker may review operational and financial data on a property basis and does not differentiate properties on a geographical basis for purposes of allocating resources or capital. Each property is considered a separate operating segment; however, each property on a stand-alone basis represents less than 10% of revenues, profit or loss, and assets of the combined reported operating segment and meets the majority of the aggregations criteria under the applicable standard.

Principles of Consolidation

The consolidated financial statements include the consolidated accounts of the Company and its investments in partnerships and limited liability companies in which the Company has control in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810 “Consolidation” (“ASC Topic 810”). The ownership interests of other investors in these entities are recorded as noncontrolling interests. All significant intercompany balances and transactions have been eliminated in consolidation. Investments in entities for which the Company has the ability to exercise significant influence over, but does not have financial or operating control, are accounted for using the equity method of accounting. Accordingly, the Company’s share of the earnings (or losses) of these entities are included in consolidated net income.

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. Operating results for the interim periods presented are not necessarily indicative of the results that may be expected for the full fiscal year. The information furnished in the accompanying consolidated financial statements reflects all adjustments that, in the opinion of management, are necessary for a fair presentation of the aforementioned consolidated financial statements for the interim periods. Such adjustments consisted of normal recurring items.

These consolidated financial statements should be read in conjunction with the Company’s 2017 Annual Report on Form 10-K, as filed with the SEC on February 27, 2018.

Use of Estimates

GAAP requires the Company’s management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The most significant assumptions and estimates relate to the valuation of real estate, depreciable lives, revenue recognition and the collectability of notes receivable and rents receivable. Application of these estimates and assumptions requires the exercise of judgment as to future uncertainties and, as a result, actual results could differ from these estimates.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update(“ASU”) No. 2014-09, Revenue from Contracts with Customers. ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 does not apply to the Company’s lease revenues, but will apply to reimbursed tenant costs. Additionally, this guidance modifies disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued ASU 2015-14, which defers the effective date of ASU 2014-09 for all entities by one year, until years beginning in 2018, with early adoption permitted but not before 2017. Entities may adopt ASU 2014-09 using either a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or a modified retrospective approach with the cumulative effect, recognized at the date of adoption. Substantially all of the Company’s revenue is derived from its leases and therefore falls outside of the scope of this guidance. The Company implemented the standard using the modified retrospective approach; however, there was no cumulative effect required to be recognized in retained earnings at the date of application. With respect to its fee-derived revenue, the Company had no changes to the timing of the Company’s revenue recognition. However, the recognition of gains on sales of properties may be impacted prospectively under limited circumstances under which collectability may not be reasonably assured or if the Company has continuing involvement with a sold property. 

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows – Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 provides guidance on certain specific cash flow issues, including, but not limited to, debt prepayment or extinguishment costs, contingent consideration payments made after a business combination and distributions received from equity method investees. ASU 2016-15 is effective for periods beginning after December 15, 2017, with early adoption permitted and shall be applied retrospectively where practicable. The Company adopted ASU 2016-15 effective January 1, 2018 and elected the “cumulative distribution approach” whereby distributions received from equity method investments would be classified as cash flows from operations to the extent of equity earnings and then as cash flows from investing activities thereafter. Upon the adoption, the Company reclassified $7.3 million of its cash inflows from investing activities to cash flows from operating activities in its historical presentation of cash flows related to its equity method investments for the three months ended March 31, 2017.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 is effective for public business entities in fiscal years beginning after December 15, 2017, with early adoption permitted. The Company adopted this guidance effective January 1, 2018. Upon the adoption, the Company reclassified $1.0 million of its cash inflows from operating activities to change in cash and restricted cash in its historical presentation of cash flows for the three months ended March 31, 2017.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations – Clarifying the Definition of a Business. ASU 2017-01 clarifies that to be considered a business, the elements must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output. The new standard illustrates the circumstances under which real estate with in-place leases would be considered a business and provides guidance for the identification of assets and liabilities in purchase accounting. ASU 2017-01 is effective for periods beginning after December 15, 2017 and has been adopted by the Company effective January 1, 2018. It is expected that the new standard will reduce the number of future real estate acquisitions that will be accounted for as business combinations and, therefore, reduce the amount of acquisition costs that will be expensed. Accordingly, the Company capitalized $0.1 million of acquisition costs during the three months ended March 31, 2018 and expensed $0.3 million of acquisition costs during the three months ended March 31, 2017.

In January 2017, the FASB issued ASU No. 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments – Equity Method and Joint Ventures (Topic 323). ASU 2017-03 amends certain SEC guidance in the FASB Accounting Standards Codification in response to SEC staff announcements made during 2016 Emerging Issues Task Force (“EITF”) meetings which addressed (i) the additional qualitative disclosures that a registrant is expected to provide when it cannot reasonably estimate the impact that ASUs 2014-09, 2016-02 and 2016-13 will have in applying the guidance in Staff Accounting Bulletin Topic 11.M and (ii) guidance in ASC 323 related to the amendments made by ASU 2014-01 regarding use of the proportional amortization method in accounting for investments in qualified affordable housing projects (announcement made at the November 17, 2016, EITF meeting). The Company adopted 2017-03 effective January 1, 2018. The adoption of ASU 2017-03 did not have a material impact on the Company’s consolidated financial statements.

In February 2017, the FASB issued ASU 2017-05, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets, which amends the guidance on nonfinancial assets in ASC 610-20. The amendments clarify that (i) a financial asset is within the scope of ASC 610-20 if it meets the definition of an in substance nonfinancial asset and may include nonfinancial assets transferred within a legal entity to a counter-party, (ii) an entity should identify each distinct nonfinancial asset or in substance nonfinancial asset promised to a counter-party and de-recognize each asset when a counter-party obtains control of it, and (iii) an entity should allocate consideration to each distinct asset by applying the guidance in ASC 606 on allocating the transaction price to performance obligations. Further, ASU 2017-05 provides guidance on accounting for partial sales of nonfinancial assets. The amendments are effective at the same time as the amendments in ASU 2014-09. The Company adopted ASU 2017-05 effective January 1, 2018. The adoption of ASU 2017-05 did not have a material impact on the Company's consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, which clarifies the scope of modification accounting with respect to changes to the terms or conditions of a share-based payment award. Modification accounting would not apply if a change to an award does not affect the total current fair value (or other applicable measurement), vesting conditions, or the classification of the award. For all entities, ASU 2017-09 is effective prospectively for awards modified in fiscal years beginning after December 15, 2017. The Company adopted ASU 2017-09 effective January 1, 2018. The adoption of ASU 2017-09 did not have a material impact on the Company's consolidated financial statements because the Company has not had significant modifications of its awards.

In August 2017, the Financial Accounting Standards Board issued ASU 2017-12, Derivatives and Hedging:Targeted Improvements to Accounting for Hedging Activities. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, with early adoption, including adoption in an interim period, permitted. The Company early adopted ASU 2017-12 effective January 1, 2018 and the adoption of ASU 2017-12 did not have a material impact on the Company's consolidated financial statements.

In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118, which allowed public companies to record provisional amounts in earnings for the year ended December 31, 2017 due to the complexities involved in accounting for the enactment of the Tax Cuts and Jobs Act. ASU 2018-05 was effective upon issuance. The Company recognized the estimated income tax effects of the Tax Cuts and Jobs Act in its 2017 Consolidated Financial Statements in accordance with SEC Staff Accounting Bulletin No. 118.

Recently Issued Accounting Pronouncements

In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. These amendments provide financial statement preparers with an option to reclassify stranded tax effects within accumulated other comprehensive income to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recorded. This guidance is effective for fiscal years beginning after December 15, 2018, and interim periods therein. Early adoption is permitted. We are currently assessing the impact this guidance will have on our consolidated financial statements.

(d) Represents a variable interest entity.

(e) The Company is entitled to a 15% return on its cumulative capital contribution which was $15.7 million and $15.4 million at March 31, 2018 and December 31, 2017, respectively.

Core Portfolio

Acquisition of Unconsolidated Investment

On January 4, 2017, an entity in which the Company owns a 20% noncontrolling interest (the “Renaissance Portfolio”), acquired a 6,200 square foot property in Alexandria, Virginia referred to as (“907 King Street”) for $3.0 million. The Renaissance Portfolio is now a 213,000 square-foot portfolio of 18 mixed-use properties, 16 of which are located in Georgetown, Washington D.C. and two of which are located in Alexandria, Virginia.

Brandywine Portfolio, Market Square and Town Center

The Company owns an interest in an approximately one million square foot retail portfolio (the “Brandywine Portfolio” joint venture) located in Wilmington, Delaware, which includes two properties referred to as “Market Square” and “Town Center.” Prior to the second quarter of 2016, the Company had a controlling interest in the Brandywine Portfolio, and it was therefore consolidated within the Company’s financial statements. During April 2016, the arrangement with the partners of the Brandywine Portfolio was modified to change the legal ownership from a partnership to a tenancy-in-common interest, as well as to provide certain participating rights to the outside partners. As a result of these modifications, the Company de-consolidated the Brandywine Portfolio and accounted for its interest under the equity method of accounting effective May 1, 2016. Furthermore, as the owners of the Brandywine Portfolio had consistent ownership interests before and after the modification and the underlying net assets were unchanged, the Company reflected the change from consolidation to equity method based upon its historical cost. The Brandywine Portfolio and Market Square ventures do not include the property held by Brandywine Holdings, an entity consolidated by the Company.

Additionally, in April 2016, the Company repaid the outstanding balance of $140.0 million of non-recourse debt collateralized by the Brandywine Portfolio and provided a note receivable collateralized by the partners’ tenancy-in-common interest in the Brandywine Portfolio for their proportionate share of the repayment. On May 1, 2017, the Company exchanged $16.0 million of the $153.4 million notes receivable (the “Brandywine Notes Receivable”) (Note 3) plus accrued interest of $0.3 million for one of the partner’s 38.89% tenancy-in-common interests in Market Square. The Company already had a 22.22% interest in Market Square and continued to apply the equity method of accounting for its aggregate 61.11% noncontrolling interest in Market Square and its 22.22% interest in Town Center through November 16, 2017. The incremental investment in Market Square was recorded at $16.3 million and the excess of this amount over the venture’s book value associated with this interest, or $9.8 million, was being amortized over the remaining depreciable lives of the venture’s assets through November 16, 2017. On November 16, 2017, the Company exchanged an additional $16.0 million of Brandywine Notes Receivable plus accrued interest of $0.6 million for the remaining 38.89% interest in Market Square, thereby obtaining a 100% controlling interest in the property. The exchange was deemed to be a business combination and as a result, the property was consolidated and a gain on change of control of $5.6 million was recorded (Note 2).

On November 16, 2017, the Company exchanged $60.7 million of the Brandywine Notes Receivable plus accrued interest of $0.9 million for one of the partner’s 38.89% tenancy-in-common interests in Town Center. The incremental investment in Town Center was recorded at $61.6 million and the excess of this amount over the venture’s book value associated with this interest, or $34.5 million, will be amortized over the remaining depreciable lives of the venture’s assets. The Company previously had a 22.22% interest in Town Center which then became 61.11% following the November 2017 transaction.

On March 28, 2018, the Company exchanged $22.0 million of its Brandywine Notes Receivable plus accrued interest of $0.3 million for one of the partner’s 14.11% tenancy-in-common interests in Town Center. The incremental investment in Town Center was recorded at $22.3 million and the excess of this amount over the venture’s book value associated with this interest, or $12.7 million, will be amortized over the remaining depreciable lives of the venture’s assets. The Company continues to apply the equity method of accounting for its aggregate 75.22% noncontrolling interest in Town Center after the March 2018 transaction.

At March 31, 2018, $38.7 million of the Brandywine Note Receivable remains outstanding (Note 3), which is collateralized by the remaining 24.78% undivided interest in Town Center.

Fund Investments

Mervyn’s I & II

In 2017, Mervyn’s I and Mervyn’s II received a total of $1.1 million in distributions from certain investments. The Company had already reduced the carrying amount of these investments to zero, and consequently the entire amount received has been reflected as equity in earnings and gains of unconsolidated affiliates in the consolidated statements of income.

Albertson’s

“Other” includes Fund II’s cost method investment in Albertson’s supermarkets among other investments. In 2017, the Company received $2.4 million in distributions from Albertson’s and reduced the carrying amount of its investment in Albertson’s to zero, reflecting the remaining $2.0 million as equity in earnings and gains of unconsolidated affiliates in the consolidated statements of income.

2018 Dispositions of Unconsolidated Investments

On January 18, 2018, Fund IV’s Broughton Street Portfolio venture sold two properties for aggregate proceeds of $8.0 million, resulting in a net loss of $0.4 million at the property level of which the Fund’s share and the Operating Partnership’s proportionate share of the loss was zero. At March 31, 2018, the Broughton Street portfolio had 16 remaining properties.

2017 Dispositions of Unconsolidated Investments

On January 31, 2017, Fund IV completed the disposition of 2819 Kennedy Boulevard, for $19.0 million less $8.4 million debt repayment for net proceeds of $10.6 million, resulting in a gain on disposition of $6.3 million at the property level, of which the Fund’s share was $6.2 million, which is included in equity in earnings and gains from unconsolidated affiliates in the consolidated statements of income. The Operating Partnership’s proportionate share of the gain was $1.4 million, net of noncontrolling interests.

(c) Includes $143.8 million and $141.1 million, respectively, of variable-rate debt that is subject to interest cap agreements.

Credit Facility

On February 20, 2018, the Company entered into a $500.0 million senior unsecured credit facility (the “Credit Facility”), comprised of a $150.0 million senior unsecured revolving credit facility (the “Revolver”), and a $350.0 million senior unsecured term loan (the “Term Loan”). The Credit Facility refinanced the Company’s existing $300.0 million credit facility (comprised of the $150.0 million Core unsecured revolving line of credit and the $150.0 million term loan), $150.0 million in Core unsecured term loans and repaid a $40.4 million mortgage secured by its 664 North Michigan Property. The Revolver and Term Loans mature on March 31, 2022 and March 31, 2023, respectively.

Mortgages Payable

During the three months endedMarch 31, 2018, the Company obtained two new non-recourse Fund mortgages totaling $39.8 million with a weighted-average interest rate of LIBOR + 2.17% collateralized by two properties and maturing in 2021. The Company entered into interest rate swap contracts to effectively fix the variable portion of the interest rates of one of these obligations with a notional value of $16.9 million at an interest rate of 2.41%. During the three months endedMarch 31, 2018, the Company repaid one Core mortgage in full, which had a total balance of $40.4 million and a weighted-average interest rate of LIBOR + 1.65%, and made scheduled principal payments of $1.9 million. At March 31, 2018 and December 31, 2017, the Company’s mortgages were collateralized by 43 and 42 properties, respectively, and the related tenant leases. Certain loans are cross-collateralized and contain cross-default provisions. The loan agreements contain customary representations, covenants and events of default. Certain loan agreements require the Company to comply with affirmative and negative covenants, including the maintenance of debt service coverage and leverage ratios. A portion of the Company’s variable-rate mortgage debt has been effectively fixed through certain cash flow hedge transactions (Note 8).

The mortgage loan related to Brandywine Holdings in the Company’s Core Portfolio amounted to $26.3 million and was in default at March 31, 2018 and December 31, 2017. This loan bears interest at 6.00%, excluding default interest of 5%, and is collateralized by a property, in which the Company holds a 22% controlling interest. In April 2017, the lender on this mortgage initiated a lawsuit against the Company for the full balance of the principal, accrued interest as well as penalties and fees aggregating approximately $32.9 million. The Company’s management believes that the mortgage is not recourse to the Company and that the suit is without merit.

Unsecured Notes Payable

The Company entered into an interest rate swap contract to effectively fix the variable portion of the interest rate with a notional value of $50.0 million at an interest rate of 2.80%.

• Fund II has a $40.0 million term loan secured by the real estate assets of City Point Phase II and guaranteed by the Company and the Operating Partnership.

Financial Instruments and Fair Value Measurements

Fair Value Disclosures [Abstract]

Financial Instruments and Fair Value Measurements

Financial Instruments and Fair Value Measurements

The fair value of an asset is defined as the exit price, which is the amount that would either be received when an asset is sold or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The guidance establishes a three-tier fair value hierarchy based on the inputs used in measuring fair value. These tiers are: Level 1, for which quoted market prices for identical instruments are available in active markets, such as money market funds, equity securities, and U.S. Treasury securities; Level 2, for which there are inputs other than quoted prices included within Level 1 that are observable for the instrument, such as certain derivative instruments including interest rate caps and interest rate swaps; and Level 3, for financial instruments or other assets/liabilities that do not fall into Level 1 or Level 2 and for which little or no market data exists, therefore requiring the Company to develop its own assumptions.

Items Measured at Fair Value on a Recurring Basis

The methods and assumptions described below were used to estimate the fair value of each class of financial instrument. For significant Level 3 items, the Company has also provided the unobservable inputs along with their weighted-average ranges.

Money Market Funds — The Company has money market funds, which are included in Cash and cash equivalents in the consolidated financial statements, are comprised of government securities and/or U.S. Treasury bills. These funds were classified as Level 1 as we used quoted prices from active markets to determine their fair values.

Derivative Assets — The Company has derivative assets, which are included in Other assets, net in the consolidated financial statements, are comprised of interest rate swaps and caps. The derivative instruments were measured at fair value using readily observable market inputs, such as quotations on interest rates, and were classified as Level 2 as these instruments are custom, over-the-counter contracts with various bank counterparties that are not traded in an active market. See “Derivative Financial Instruments,” below.

Derivative Liabilities — The Company has derivative liabilities, which are included in Accounts payable and other liabilities in the consolidated financial statements, are comprised of interest rate swaps and caps. These derivative instruments were measured at fair value using readily observable market inputs, such as quotations on interest rates, and were classified as Level 2 because they are custom, over-the-counter contracts with various bank counterparties that are not traded in an active market. See “Derivative Financial Instruments,” below.

The Company did not have any transfers into or out of Level 1, Level 2, and Level 3 measurements during the three months endedMarch 31, 2018 or 2017.

The following table presents the Company’s fair value hierarchy for those assets and liabilities measured at fair value on a recurring basis (in thousands):

	March 31, 2018						December 31, 2017
	Level 1		Level 2		Level 3		Level 1		Level 2		Level 3
Assets
Money Market Funds	$	105	$	—	$	—	$	3	$	—	$	—
Derivative financial instruments	—		9,958		—		—		4,402		—
Liabilities
Derivative financial instruments	—		1,238		—		—		1,467		—

In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

All of the Company’s derivative instruments have been designated as cash flow hedges and hedge the future cash outflows on variable-rate debt (Note 7). It is estimated that approximately $1.1 million included in accumulated other comprehensive (loss) income related to derivatives will be reclassified to interest expense in the 2018 results of operation. As of March 31, 2018 and December 31, 2017, no derivatives were designated as fair value hedges or hedges of net investments in foreign operations. Additionally, the Company does not use derivatives for trading or speculative purposes and currently does not have any derivatives that are not designated hedges.

Risk Management Objective of Using Derivatives

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of its debt funding and, from time to time, through the use of derivative financial instruments. The Company enters into derivative financial instruments to manage exposures that result in the receipt or payment of future known and uncertain cash amounts, the values of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s investments and borrowings.

The Company is exposed to credit risk in the event of non-performance by the counterparties to the Swaps if the derivative position has a positive balance. The Company believes it mitigates its credit risk by entering into Swaps with major financial institutions. The Company continually monitors and actively manages interest costs on its variable-rate debt portfolio and may enter into additional interest rate swap positions or other derivative interest rate instruments based on market conditions. The Company has not entered, and does not plan to enter, into any derivative financial instruments for trading or speculative purposes.

The following table presents the location in the financial statements of the income (losses) recognized related to the Company’s cash flow hedges (in thousands):

	Three Months Ended March 31,

Amount of loss related to the effective portion subsequently reclassified to earnings	—		—
Amount of gain (loss) related to the ineffective portion and amount excluded from effectiveness testing	—		—

Credit Risk-Related Contingent Features

The Company has agreements with each of its Swap counterparties that contain a provision whereby if the Company defaults on certain of its unsecured indebtedness the Company could also be declared in default on its swaps, resulting in an acceleration of payment under the swaps.

Other Financial Instruments

The Company’s other financial instruments had the following carrying values and fair values as of the dates shown (dollars in thousands):

__________

(a) The Company determined the estimated fair value of these financial instruments using a discounted cash flow model with rates that take into account the credit of the borrower or tenant, where applicable, and interest rate risk. The Company also considered the value of the underlying collateral, taking into account the quality of the collateral, the credit quality of the borrower, the time until maturity and the current market interest rate environment.

(b) Represents Fund II’s cost-method investment in Albertson’s supermarkets (Note 4).

(c) The Company determined the estimated fair value of the unsecured notes payable and unsecured line of credit using quoted market prices in an open market with limited trading volume where available. In cases where there was no trading volume, the Company determined the estimated fair value using a discounted cash flow model using a rate that reflects the average yield of similar market participants.

The Company’s cash and cash equivalents, restricted cash, accounts receivable, accounts payable and certain financial instruments included in other assets and other liabilities had fair values that approximated their carrying values at March 31, 2018.

(a) Noncontrolling interests in the Operating Partnership are comprised of (i) the limited partners’ 3,328,873 Common OP Units at March 31, 2018 and December 31, 2017; (ii) 188 Series A Preferred OP Units at March 31, 2018 and December 31, 2017; (iii) 136,593 Series C Preferred OP Units at March 31, 2018 and December 31, 2017; and (iv) 2,619,872 and 2,274,147 LTIP units as of at March 31, 2018 and December 31, 2017, respectively, as discussed in Share Incentive Plan (Note 13). Distributions declared for Preferred OP Units are reflected in net income in the table above.

(b) Noncontrolling interests in partially-owned affiliates comprise third-party interests in Funds II, III, IV and V, and Mervyns I and II, and six other subsidiaries.

(c) Adjustment reflects the difference between the fair value of the consideration received or paid and the book value of the Common Shares, Common OP Units, Preferred OP Units, and LTIP Units involving changes in ownership (the “Rebalancing”).

Preferred OP Units

There were no issuances of Preferred OP Units during the three months endedMarch 31, 2018.

In 1999 the Operating Partnership issued 1,580 Series A Preferred OP Units in connection with the acquisition of a property, which have a stated value of $1,000 per unit, and are entitled to a preferred quarterly distribution of the greater of (i) $22.50 (9% annually) per Series A Preferred OP Unit or (ii) the quarterly distribution attributable to a Series A Preferred OP Unit if such unit was converted into a Common OP Unit. Through March 31, 2018, 1,392 Series A Preferred OP Units were converted into 185,600 Common OP Units and then into Common Shares. The 188 remaining Series A Preferred OP Units are currently convertible into Common OP Units based on the stated value divided by $7.50. Either the Company or the holders can currently call for the conversion of the Series A Preferred OP Units at the lesser of $7.50 or the market price of the Common Shares as of the conversion date.

During 2016, the Operating Partnership issued 442,478 Common OP Units and 141,593 Series C Preferred OP Units to a third party to acquire Gotham Plaza (Note 4). The Series C Preferred OP Units have a value of $100.00 per unit and are entitled to a preferred quarterly distribution of $0.9375 per unit and are convertible into Common OP Units at a rate based on the share price at the time of conversion. If the share price is below $28.80 on the conversion date, each Series C Preferred OP Unit will be convertible into 3.4722 Common OP Units. If the share price is between $28.80 and $35.20 on the conversion date, each Series C Preferred OP Unit will be convertible into a number of Common OP Units equal to $100.00 divided by the closing share price. If the share price is above $35.20 on the conversion date, each Series C Preferred OP Unit will be convertible into 2.8409 Common OP Units. The Series C Preferred OP Units have a mandatory conversion date of December 31, 2025, at which time all units that have not been converted will automatically be converted into Common OP Units based on the same calculations. Through March 31, 2018, 5,000 Series C Preferred OP Units were converted into 17,165 Common OP Units and then into Common Shares.

Leases

Operating Leases

The Company is engaged in the operation of shopping centers and other retail properties that are either owned or, with respect to certain shopping centers, operated under long-term ground leases that expire at various dates through June 20, 2066, with renewal options. Space in the shopping centers is leased to tenants pursuant to agreements that provide for terms ranging generally from one month to ninety-nine years and generally provide for additional rents based on certain operating expenses as well as tenants’ sales volumes.

The Company leases land at seven of its shopping centers, which are accounted for as operating leases and generally provide the Company with renewal options. Ground rent expense was $0.4 million and $0.8 million (including capitalized ground rent at a property under development of $0.2 million and $0.1 million) for the three months endedMarch 31, 2018 and 2017, respectively. The leases terminate at various dates between 2020 and 2066. These leases provide the Company with options to renew for additional terms aggregating from 25 to 71 years. The Company also leases space for its corporate office. Office rent expense under this lease was $0.2 million for each of the three months endedMarch 31, 2018 and 2017.

Capital Lease

During 2016, the Company entered into a 49-year master lease at 991 Madison Avenue, which is accounted for as a capital lease. During each of the three months endedMarch 31, 2018 and 2017, payments for this lease totaled $0.6 million. The lease was initially valued at $76.6 million, which represents the total discounted payments to be made under the lease. The property under the capital lease is included in Note 2.

Lease Obligations

The scheduled future minimum (i) rental revenues from rental properties under the terms of all non-cancelable tenant leases, assuming no new or renegotiated leases or option extensions for such premises and (ii) rental payments under the terms of all non-cancelable operating and capital leases in which the Company is the lessee, principally for office space and ground leases, as of March 31, 2018, are summarized as follows (in thousands):

Year Ending December 31,	Minimum Rental Revenues		Minimum Rental Payments
2018 (Remainder)	$	125,069	$	4,546
2019	169,873		4,565
2020	155,238		4,256
2021	135,874		4,364
2022	116,972		4,400
Thereafter	527,122		183,911
Total	$	1,230,148	$	206,042

A ground lease expiring during 2078 provides the Company with an option to purchase the underlying land during 2031. If the Company does not exercise the option, the rents that will be due are based on future values and as such are not determinable at this time. Accordingly, the above table does not include rents for this lease beyond 2031.

During the three months endedMarch 31, 2018 and 2017, no single tenant collectively comprised more than 10% of the Company’s consolidated total revenues.

The Company has three reportable segments: Core Portfolio, Funds and Structured Financing. The Company’s Core Portfolio consists primarily of high-quality retail properties located primarily in high-barrier-to-entry, densely-populated metropolitan areas with a long-term investment horizon. The Company’s Funds hold primarily retail real estate in which the Company co-invests with high-quality institutional investors. The Company’s Structured Financing segment consists of earnings and expenses related to notes and mortgages receivable which are held within the Core Portfolio or the Funds (Note 3). Fees earned by the Company as the general partner or managing member of the Funds are eliminated in the Company’s consolidated financial statements and are not presented in the Company’s segments.

Share Incentive and Other Compensation

Share Incentive and Other Compensation

Share Incentive and Other Compensation

Share Incentive Plan

The Second Amended and Restated 2006 Incentive Plan (the “Share Incentive Plan”) authorizes the Company to issue options, Restricted Shares, LTIP Units and other securities (collectively “Awards”) to, among others, the Company’s officers, trustees and employees. At March 31, 2018 a total of 1,223,815 shares remained available to be issued under the Share Incentive Plan.

Restricted Shares and LTIP Units

During the three months endedMarch 31, 2018, the Company issued 381,821 LTIP Units and 5,768 Restricted Share Units to employees of the Company pursuant to the Share Incentive Plan. These awards were measured at their fair value on the grant date, based on a valuation provided by an independent third-party appraiser incorporating the following factors:

• A portion of these annual equity award is granted in performance-based Restricted Share Units or LTIP Units that may be earned based on the Company’s attainment of specified relative total shareholder returns (“Relative TSR”) hurdles.

• In the event the Relative TSR percentile falls between the 25th percentile and the 50th percentile, Relative TSR vesting percentage is determined using a straight line linear interpolation between 50% and 100% and in the event that the Relative TSR percentile falls between the 50th percentile and 75th percentile, the Relative TSR vesting percentage is determined using a straight line linear interpolation between 100% and 200%.

• Two-thirds (2/3) of the performance-based LTIP Units will vest based on the Company’s total shareholder return (“TSR”) for the three-year forward-looking performance period ending December 31, 2020 relative to the constituents of the SNL U.S. REIT Retail Shopping Center Index and one-third (1/3) on the Company’s TSR for the three-year forward-looking performance period as compared to the constituents of the SNL U.S. REIT Retail Index (both on a non-weighted basis).

• If the Company’s performance fails to achieve the aforementioned hurdles at the culmination of the three-year performance period, all performance-based shares will be forfeited. Any earned performance-based shares vest 60% at the end of the performance period, with the remaining 40% of shares vesting ratably over the next two years.

The total value of the above Restricted Share Units and LTIP Units as of the grant date was $10.6 million. Total long-term incentive compensation expense, including the expense related to the Share Incentive Plan, was $2.2 million and $1.9 million for the three months endedMarch 31, 2018 and 2017, respectively and is recorded in General and Administrative on the Consolidated Statements of Income.

In addition, members of the Board of Trustees (the “Board”) have been issued shares and units under the Share Incentive Plan. During 2017, the Company issued 11,814 Restricted Shares and 11,105 LTIP Units to Trustees of the Company in connection with Trustee fees. Vesting with respect to 3,864 of the Restricted Shares and 5,805 of the LTIP Units will be on the first anniversary of the date of issuance and 7,950 of the Restricted Shares and 5,300 of the LTIP Units vest over three years with 33% vesting on each of the next three anniversaries of the issuance date. The Restricted Shares do not carry voting rights or other rights of Common Shares until vesting and may not be transferred, assigned or pledged until the recipients have a vested non-forfeitable right to such shares. Dividends are not paid currently on unvested Restricted Shares, but are paid cumulatively from the issuance date through the applicable vesting date of such Restricted Shares. Total trustee fee expense, including the expense related to the Share Incentive Plan, was $0.3 million for each of the three months endedMarch 31, 2018 and 2017, respectively.

In 2009, the Company adopted the Long Term Investment Alignment Program (the “Program”) pursuant to which the Company may grant awards to employees, entitling them to receive up to 25% of any potential future payments of Promote to the Operating Partnership from Funds III and IV. The Company has granted such awards to employees representing 25% of the potential Promote payments from Fund III to the Operating Partnership and 22.8% of the potential Promote payments from Fund IV to the Operating Partnership. Payments to senior executives under the Program require further Board approval at the time any potential payments are due pursuant to these grants. Compensation relating to these awards will be recognized in each reporting period in which Board approval is granted.

As payments to other employees are not subject to further Board approval, compensation relating to these awards will be recorded based on the estimated fair value at each reporting period in accordance with ASC Topic 718, Compensation– Stock Compensation. The awards in connection with Fund IV were determined to have no intrinsic value as of March 31, 2018.

Compensation expense of $0 million and $0.3 million was recognized for the three months endedMarch 31, 2018 and 2017, respectively, related to the Program in connection with Fund III.

A summary of the status of the Company’s unvested Restricted Shares and LTIP Units is presented below:

The weighted-average grant date fair value for Restricted Shares and LTIP Units granted for the three months endedMarch 31, 2018 and the year ended December 31, 2017 were $27.26 and $31.69, respectively. As of March 31, 2018, there was $21.0 million of total unrecognized compensation cost related to unvested share-based compensation arrangements granted under the Share Incentive Plan. That cost is expected to be recognized over a weighted-average period of 1.9 years. The total fair value of Restricted Shares that vested for each of the three months endedMarch 31, 2018 and the year ended December 31, 2017, was $0.7 million. The total fair value of LTIP Units that vested during the three months endedMarch 31, 2018 and the year ended December 31, 2017, was $8.8 million and $7.3 million, respectively.

Other Plans

On a combined basis, the Company incurred a total of $0.1 million related to the following employee benefit plans for each of the three months endedMarch 31, 2018 and 2017, respectively:

Employee Share Purchase Plan

The Acadia Realty Trust Employee Share Purchase Plan (the “Purchase Plan”), allows eligible employees of the Company to purchase Common Shares through payroll deductions. The Purchase Plan provides for employees to purchase Common Shares on a quarterly basis at a 15% discount to the closing price of the Company’s Common Shares on either the first day or the last day of the quarter, whichever is lower. A participant may not purchase more the $25,000 in Common Shares per year. Compensation expense will be recognized by the Company to the extent of the above discount to the closing price of the Common Shares with respect to the applicable quarter. A total of 943 and 841 Common Shares were purchased by employees under the Purchase Plan., for each of the three months endedMarch 31, 2018 and 2017, respectively.

Deferred Share Plan

During May of 2006, the Company adopted a Trustee Deferral and Distribution Election, under which the participating Trustees earn deferred compensation.

Employee 401(k) Plan

The Company maintains a 401(k) plan for employees under which the Company currently matches 50% of a plan participant’s contribution up to 6% of the employee’s annual salary. A plan participant may contribute up to a maximum of 15% of their compensation, up to $18,000, for the year ending December 31, 2018.

Earnings Per Common Share

Mar. 31, 2018

Earnings Per Share [Abstract]

Earnings Per Common Share

Earnings Per Common Share

Basic earnings per Common Share is computed by dividing net income attributable to Common Shareholders by the weighted average Common Shares outstanding (Note 10, Note 15). During the periods presented, the Company had unvested LTIP Units which provide for non-forfeitable rights to dividend equivalent payments. Accordingly, these unvested LTIP Units are considered participating securities and are included in the computation of basic earnings per Common Share pursuant to the two-class method.

Diluted earnings per Common Share reflects the potential dilution of the conversion of obligations and the assumed exercises of securities including the effects of restricted share units (“Restricted Share Units”) issued under the Company’s Share Incentive Plans (Note 13). The effect of such shares is excluded from the calculation of earnings per share when anti-dilutive as indicated in the table below.

The effect of the conversion of Common OP Units is not reflected in the computation of basic and diluted earnings per share, as they are exchangeable for Common Shares on a one-for-one basis. The income allocable to such units is allocated on this same basis and reflected as noncontrolling interests in the accompanying consolidated financial statements. As such, the assumed conversion of these units would have no net impact on the determination of diluted earnings per share.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Segments

Segments

At March 31, 2018, the Company had three reportable operating segments: Core Portfolio, Funds and Structured Financing. The Company’s chief operating decision maker may review operational and financial data on a property basis and does not differentiate properties on a geographical basis for purposes of allocating resources or capital. Each property is considered a separate operating segment; however, each property on a stand-alone basis represents less than 10% of revenues, profit or loss, and assets of the combined reported operating segment and meets the majority of the aggregations criteria under the applicable standard.

Principles of Consolidation

Principles of Consolidation

The consolidated financial statements include the consolidated accounts of the Company and its investments in partnerships and limited liability companies in which the Company has control in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810 “Consolidation” (“ASC Topic 810”). The ownership interests of other investors in these entities are recorded as noncontrolling interests. All significant intercompany balances and transactions have been eliminated in consolidation. Investments in entities for which the Company has the ability to exercise significant influence over, but does not have financial or operating control, are accounted for using the equity method of accounting. Accordingly, the Company’s share of the earnings (or losses) of these entities are included in consolidated net income.

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. Operating results for the interim periods presented are not necessarily indicative of the results that may be expected for the full fiscal year. The information furnished in the accompanying consolidated financial statements reflects all adjustments that, in the opinion of management, are necessary for a fair presentation of the aforementioned consolidated financial statements for the interim periods. Such adjustments consisted of normal recurring items.

These consolidated financial statements should be read in conjunction with the Company’s 2017 Annual Report on Form 10-K, as filed with the SEC on February 27, 2018.

Use of Estimates

Use of Estimates

GAAP requires the Company’s management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The most significant assumptions and estimates relate to the valuation of real estate, depreciable lives, revenue recognition and the collectability of notes receivable and rents receivable. Application of these estimates and assumptions requires the exercise of judgment as to future uncertainties and, as a result, actual results could differ from these estimates.

Recently Issued Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update(“ASU”) No. 2014-09, Revenue from Contracts with Customers. ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 does not apply to the Company’s lease revenues, but will apply to reimbursed tenant costs. Additionally, this guidance modifies disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued ASU 2015-14, which defers the effective date of ASU 2014-09 for all entities by one year, until years beginning in 2018, with early adoption permitted but not before 2017. Entities may adopt ASU 2014-09 using either a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or a modified retrospective approach with the cumulative effect, recognized at the date of adoption. Substantially all of the Company’s revenue is derived from its leases and therefore falls outside of the scope of this guidance. The Company implemented the standard using the modified retrospective approach; however, there was no cumulative effect required to be recognized in retained earnings at the date of application. With respect to its fee-derived revenue, the Company had no changes to the timing of the Company’s revenue recognition. However, the recognition of gains on sales of properties may be impacted prospectively under limited circumstances under which collectability may not be reasonably assured or if the Company has continuing involvement with a sold property. 

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows – Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 provides guidance on certain specific cash flow issues, including, but not limited to, debt prepayment or extinguishment costs, contingent consideration payments made after a business combination and distributions received from equity method investees. ASU 2016-15 is effective for periods beginning after December 15, 2017, with early adoption permitted and shall be applied retrospectively where practicable. The Company adopted ASU 2016-15 effective January 1, 2018 and elected the “cumulative distribution approach” whereby distributions received from equity method investments would be classified as cash flows from operations to the extent of equity earnings and then as cash flows from investing activities thereafter. Upon the adoption, the Company reclassified $7.3 million of its cash inflows from investing activities to cash flows from operating activities in its historical presentation of cash flows related to its equity method investments for the three months ended March 31, 2017.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 is effective for public business entities in fiscal years beginning after December 15, 2017, with early adoption permitted. The Company adopted this guidance effective January 1, 2018. Upon the adoption, the Company reclassified $1.0 million of its cash inflows from operating activities to change in cash and restricted cash in its historical presentation of cash flows for the three months ended March 31, 2017.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations – Clarifying the Definition of a Business. ASU 2017-01 clarifies that to be considered a business, the elements must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output. The new standard illustrates the circumstances under which real estate with in-place leases would be considered a business and provides guidance for the identification of assets and liabilities in purchase accounting. ASU 2017-01 is effective for periods beginning after December 15, 2017 and has been adopted by the Company effective January 1, 2018. It is expected that the new standard will reduce the number of future real estate acquisitions that will be accounted for as business combinations and, therefore, reduce the amount of acquisition costs that will be expensed. Accordingly, the Company capitalized $0.1 million of acquisition costs during the three months ended March 31, 2018 and expensed $0.3 million of acquisition costs during the three months ended March 31, 2017.

In January 2017, the FASB issued ASU No. 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments – Equity Method and Joint Ventures (Topic 323). ASU 2017-03 amends certain SEC guidance in the FASB Accounting Standards Codification in response to SEC staff announcements made during 2016 Emerging Issues Task Force (“EITF”) meetings which addressed (i) the additional qualitative disclosures that a registrant is expected to provide when it cannot reasonably estimate the impact that ASUs 2014-09, 2016-02 and 2016-13 will have in applying the guidance in Staff Accounting Bulletin Topic 11.M and (ii) guidance in ASC 323 related to the amendments made by ASU 2014-01 regarding use of the proportional amortization method in accounting for investments in qualified affordable housing projects (announcement made at the November 17, 2016, EITF meeting). The Company adopted 2017-03 effective January 1, 2018. The adoption of ASU 2017-03 did not have a material impact on the Company’s consolidated financial statements.

In February 2017, the FASB issued ASU 2017-05, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets, which amends the guidance on nonfinancial assets in ASC 610-20. The amendments clarify that (i) a financial asset is within the scope of ASC 610-20 if it meets the definition of an in substance nonfinancial asset and may include nonfinancial assets transferred within a legal entity to a counter-party, (ii) an entity should identify each distinct nonfinancial asset or in substance nonfinancial asset promised to a counter-party and de-recognize each asset when a counter-party obtains control of it, and (iii) an entity should allocate consideration to each distinct asset by applying the guidance in ASC 606 on allocating the transaction price to performance obligations. Further, ASU 2017-05 provides guidance on accounting for partial sales of nonfinancial assets. The amendments are effective at the same time as the amendments in ASU 2014-09. The Company adopted ASU 2017-05 effective January 1, 2018. The adoption of ASU 2017-05 did not have a material impact on the Company's consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, which clarifies the scope of modification accounting with respect to changes to the terms or conditions of a share-based payment award. Modification accounting would not apply if a change to an award does not affect the total current fair value (or other applicable measurement), vesting conditions, or the classification of the award. For all entities, ASU 2017-09 is effective prospectively for awards modified in fiscal years beginning after December 15, 2017. The Company adopted ASU 2017-09 effective January 1, 2018. The adoption of ASU 2017-09 did not have a material impact on the Company's consolidated financial statements because the Company has not had significant modifications of its awards.

In August 2017, the Financial Accounting Standards Board issued ASU 2017-12, Derivatives and Hedging:Targeted Improvements to Accounting for Hedging Activities. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, with early adoption, including adoption in an interim period, permitted. The Company early adopted ASU 2017-12 effective January 1, 2018 and the adoption of ASU 2017-12 did not have a material impact on the Company's consolidated financial statements.

In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118, which allowed public companies to record provisional amounts in earnings for the year ended December 31, 2017 due to the complexities involved in accounting for the enactment of the Tax Cuts and Jobs Act. ASU 2018-05 was effective upon issuance. The Company recognized the estimated income tax effects of the Tax Cuts and Jobs Act in its 2017 Consolidated Financial Statements in accordance with SEC Staff Accounting Bulletin No. 118.

Recently Issued Accounting Pronouncements

In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. These amendments provide financial statement preparers with an option to reclassify stranded tax effects within accumulated other comprehensive income to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recorded. This guidance is effective for fiscal years beginning after December 15, 2018, and interim periods therein. Early adoption is permitted. We are currently assessing the impact this guidance will have on our consolidated financial statements.
