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 September 30, 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 September 30, 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 52 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 170 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 or invested 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 September 30, 2018		Unfunded Commitment		Equity Interest Held By Operating Partnership^(a)			Preferred Return			Total Distributions as of September 30, 2018 ^(b)
Fund II and Mervyns II ^(c)	6/2004		28.33	%	$	347.1	$	—		28.33	%		8	%	$	146.6
Fund III	5/2007		24.54	%		423.9		26.1		24.54	%		6	%		551.9
Fund IV	5/2012		23.12	%		420.8		109.2		23.12	%		6	%		147.4
Fund V	8/2016		20.10	%		85.1		434.9		20.10	%		6	%		—

(a)	Amount represents the current economic ownership at September 30, 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.

(c)	During April 2018, a distribution of $15.0 million was made to the Fund II investors, including $4.3 million to the Operating Partnership. This amount remains subject to re-contribution to Fund II until April 2021.

Basis of Presentation

Segments

At September 30, 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 aggregation criteria under the applicable standard.

Principles of Consolidation

The interim 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 interim 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 interim 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 interim consolidated 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 does apply to certain 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. 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 effective January 1, 2018, 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 revenue recognition. However, the recognition of gains on dispositions of properties may be impacted prospectively in 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. The Company adopted ASU 2016-15 effective January 1, 2018 and elected the “cumulative distribution approach” whereby distributions received from equity method investments are classified as cash flows from operations to the extent of equity earnings and then as cash flows from investing activities thereafter. Accordingly, the Company has reclassified $6.3 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 nine months ended September 30, 2017.

In November 2016, the FASB issued ASU No. 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. The Company adopted this guidance effective January 1, 2018. Accordingly, the Company has reclassified $3.5 million of its cash inflows from operating activities and $0.1 million of its cash outflows from financing activities to change in cash and restricted cash in its historical presentation of cash flows for the nine months ended September 30, 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 $0.2 million of acquisition costs during the nine months ended September 30, 2018 and expensed $0.9 million of acquisition costs during the nine months ended September 30, 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 No. 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 No. 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 FASB issued ASU No. 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 No. 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

Lease Accounting

In February 2016, the FASB issued ASU No. 2016-02, Leases. ASU 2016-02 outlines a new model for accounting by lessees, whereby their rights and obligations under substantially all leases, existing and new, will be capitalized and recorded on the balance sheet. For lessors, however, the accounting remains largely unchanged from the current model, with the distinction between operating, sales-type and direct-financing leases retained, but updated to align with certain changes to the lessee model and the new revenue recognition standard discussed above. Under the new guidance, contract consideration will be allocated to its lease components (such as the lease of our retail properties) and non-lease components (such as maintenance). For us as a lessor, any non-lease components will be accounted for under ASC Topic 606, Revenue from Contracts with Customers, unless the Company elects a lessor practical expedient to not separate the nonlease components from the associated lease component (see discussion below). The new guidance also includes a definition of initial direct costs that is narrower than the prior definition in current GAAP (Topic 840, Leases). This will result in a change to the accounting for our internal leasing costs, which will be expensed as incurred, as opposed to being capitalized and deferred. Commissions subsequent to successful lease execution will continue to be capitalized. ASU 2016-02 is effective for the Company beginning January 1, 2019 and will require extensive quantitative and qualitative disclosures.

ASU 2016-02 initially provided for one retrospective transition method; however, a second transition method was later added with ASU 2018-11 as described below. To ease the transition, the new lease accounting guidance permits companies to utilize certain practical expedients in their implementation of the new standard:

•

A package of three practical expedients that must be elected together for all leases and includes: (i) not reassessing expired or existing contracts as to whether they are or contain leases; (ii) not reassessing lease classification of existing leases and (iii) not reassessing the amount of capitalized initial direct costs for existing leases;

•

ASU 2016-02 also includes a practical expedient to use hindsight in determining the lease term or assessing purchase options for existing leases and in assessing impairment of right of use assets;

•

ASU 2018-01, Land Easements Practical Expedient for Transition to Topic 842 added a transition practical expedient to not reassess existing or expired land easement agreements not previously accounted for as leases; and

•

A new practical expedient under ASU 2018-11, described below.

In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases. These amendments provide minor clarifications and corrections to ASU 2016-02, Leases (Topic 842).

In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements. The amendments in this Update provide entities with an additional optional transition method to adopt ASU 2016-02. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity’s reporting under this additional transition method for the comparative periods presented in the financial statements in which it adopts the new leases standard would continue to be in accordance with current GAAP (Topic 840, Leases). The amendments in this Update also provide lessors with a practical expedient, by class of underlying asset, to make a policy election to not separate non-lease components from the associated lease component and, instead, to account for those components as a single component if the non-lease components otherwise would be accounted for under the new revenue guidance (Topic 606). Conditions are required to elect the practical expedient, and if met, the single component will be accounted for under either under Topic 842 or Topic 606 depending on which component(s) are predominant. The lessor practical expedient to not separate nonlease components from the associated component must be elected for all existing and new leases.

The Company will adopt ASU No. 2016-02 (as amended by subsequent ASUs) effective January 1, 2019 utilizing the new transition method described in ASU 2018-11 and will avail itself of all the available practical expedients described above except it will not use hindsight in determining the lease term or assessing purchase options for existing leases and in assessing impairment of right of use assets. As lessor, the Company expects that post-adoption substantially all existing leases will have no change in the timing of revenue recognition until their expiration or termination. For common area maintenance income, currently reported within expense reimbursements, while this will be considered a nonlease component within the scope of Topic 606 for new leases, we expect to elect the lessor practical expedient to not separate maintenance from the associated lease for all existing and new leases and to account for the combined component as a single lease component. The Company is still evaluating the effect of electing this lessor practical expedient on the presentation within the statement of income. The timing of revenue recognition is expected to be the same for the majority of the Company’s new leases as compared to similar existing leases. After adoption, the Company will no longer capitalize a significant portion of internal leasing costs that were previously capitalized (the Company capitalized $1.4 million and $1.3 million of internal leasing costs during the nine months ended September 30, 2018 and the year ended December 31, 2017, respectively).

As a lessee, the Company is party to several equipment, ground, and office leases with future payment obligations aggregating approximately $204.0 million at September 30, 2018 for which the Company expects to record right-of-use assets and lease liabilities at the present value of the remaining minimum rental payments upon adoption of ASU 2016-02. As lessee, the Company will apply the following practical expedients in the implementation ASU 2016-02: (i) to not separate non-lease components from the associated lease component as described above and (ii) to not apply the right-of-use recognition requirements to short-term leases.
