Organization and Basis of Presentation	'
	Organization and Basis of Presentation
	Retail Properties of America, Inc. (the Company) was formed on March 5, 2003 to own and operate high quality, strategically located shopping centers in the United States.
	All share amounts and dollar amounts in this Quarterly Report are stated in thousands with the exception of per share amounts and per square foot amounts.
	The Company has elected to be taxed as a real estate investment trust (REIT) under the Internal Revenue Code of 1986, as amended (the Code). The Company believes it qualifies for taxation as a REIT and, as such, the Company generally will not be subject to U.S. federal income tax on taxable income that is distributed to shareholders. If the Company fails to qualify as a REIT in any taxable year, the Company will be subject to U.S. federal income tax on its taxable income at regular corporate tax rates. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income, property or net worth and U.S. federal income and excise taxes on its undistributed income. The Company has one wholly-owned subsidiary that has jointly elected to be treated as a taxable REIT subsidiary (TRS) for U.S. federal income tax purposes. A TRS is taxed on its taxable income at regular corporate tax rates. The income tax expense incurred as a result of the TRS did not have a material impact on the Company’s accompanying condensed consolidated financial statements.
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. For example, significant estimates and assumptions have been made with respect to useful lives of assets, capitalization of development and leasing costs, fair value measurements, provision for impairment, including estimates of holding periods, capitalization rates and discount rates (where applicable), provision for income taxes, recoverable amounts of receivables, deferred taxes and initial valuations and related amortization periods of deferred costs and intangibles, particularly with respect to property acquisitions. Actual results could differ from those estimates.
	The accompanying condensed consolidated financial statements include the accounts of the Company, as well as all wholly-owned subsidiaries and consolidated joint venture investments. Wholly-owned subsidiaries generally consist of limited liability companies (LLCs), limited partnerships (LPs) and statutory trusts.
	The Company’s property ownership as of June 30, 2014 is summarized below:


		Wholly-owned	Consolidated
			Joint Ventures (a)
	Operating properties (b)	233	—

	Development properties	2	1


	(a)	The Company has a 50% ownership interest in one LLC.

	(b)	Excludes one wholly-owned property classified as held for sale as of June 30, 2014.
	Noncontrolling interest is the portion of equity in a consolidated subsidiary not attributable, directly or indirectly, to the Company. In the condensed consolidated statements of operations and other comprehensive income, revenues, expenses and net income or loss from less-than-wholly-owned consolidated subsidiaries are reported at the consolidated amounts, including both the amounts attributable to common shareholders and noncontrolling interests. Condensed consolidated statements of equity are included in the quarterly financial statements, including beginning balances, activity for the period and ending balances for total shareholders’ equity, noncontrolling interests and total equity. Noncontrolling interests are adjusted for additional contributions from and distributions to noncontrolling interest holders, as well as the noncontrolling interest holders’ share of the net income or loss of each respective entity, as applicable. As of June 30, 2014, the Company is the controlling member in one less-than-wholly-owned consolidated entity.
	The Company evaluates the classification and presentation of noncontrolling interests associated with its consolidated joint venture investments on an ongoing basis as facts and circumstances necessitate. No adjustment to the carrying value of the noncontrolling interests in the Company’s consolidated joint venture investments was made during the six months ended June 30, 2014 and 2013.

	Summary of Significant Accounting Policies
	Refer to the Company’s 2013 Annual Report on Form 10-K for a summary of the Company’s significant accounting policies. Except as disclosed below, there have been no changes to the Company’s significant accounting policies in the six months ended June 30, 2014.
	Recent Accounting Pronouncements
	Effective January 1, 2014, companies are required to present unrecognized tax benefits as a reduction to deferred tax assets when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. To the extent none of these are available at the reporting date, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The adoption of this pronouncement did not have any effect on the Company’s condensed consolidated financial statements.
	Effective January 1, 2015, with early adoption permitted effective January 1, 2014, the definition of discontinued operations has been revised to limit what qualifies for this classification and presentation to disposals of components of a company that represent strategic shifts that have, or will have, a major effect on a company’s operations and financial results. Required expanded disclosures for disposals or disposal groups that qualify for discontinued operations are intended to provide users of financial statements with enhanced information about the assets, liabilities, revenues and expenses of such discontinued operations. In addition, in accordance with this pronouncement, companies are required to disclose the pretax profit or loss of an individually significant component that does not qualify for discontinued operations treatment. While the threshold for a disposal or disposal group to qualify for discontinued operations treatment has been revised, this pronouncement retains the held for sale classification and presentation concepts of previous authoritative literature. Accordingly, under this pronouncement, a disposal or disposal group may qualify for held for sale classification but not meet the threshold for discontinued operations treatment. The Company has elected to early adopt this pronouncement effective January 1, 2014. The adoption, which is applied prospectively, is anticipated to substantially reduce the number of the Company’s transactions, going forward, that qualify for discontinued operations as compared to historical results. Upon adoption of this pronouncement effective January 1, 2014, the investment properties that were sold or held for sale during 2014, except for Riverpark Phase IIA, which qualified for discontinued operations treatment under the previous standard, did not qualify for discontinued operations and, as such, are reflected in continuing operations on the condensed consolidated statements of operations and other comprehensive income.
	Effective January 1, 2016, with early adoption permitted effective January 1, 2014, companies that grant their employees share-based payments in which the terms of the award provide that a performance target which affects vesting could be achieved after the requisite service period will be required to treat that feature as a performance condition. The Company has elected to early adopt this pronouncement effective January 1, 2014. The adoption of this pronouncement did not have any effect on the Company’s condensed consolidated financial statements.
	Effective January 1, 2017, companies will be required to apply a five-step model in accounting for revenue arising from contracts with customers. The core principle of the revised revenue model is that a company recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Lease contracts will be excluded from this revenue recognition criteria; however, the sale of real estate will be required to follow the new model. Expanded quantitative and qualitative disclosures regarding revenue recognition will be required for contracts that are subject to this guidance. The Company does not expect the adoption will have a material effect on its consolidated financial statements, however it will continue to evaluate this assessment until the guidance becomes effective.

	Acquisitions
	The Company acquired seven properties and one outparcel at an existing consolidated multi-tenant retail operating property during the six months ended June 30, 2014, as summarized below.
	On June 23, 2014, the Company paid $6,369 using available cash on hand to acquire an 8,500 square foot single-user outparcel at Southlake Town Square, one of the Company’s existing consolidated multi-tenant retail operating properties, located in Southlake, Texas.
	As discussed in Note 10, on June 5, 2014, the Company dissolved its joint venture arrangement with its partner in MS Inland Fund, LLC (MS Inland) by acquiring its partner’s 80% ownership interest in the six multi-tenant retail properties owned by the joint venture (collectively, the MS Inland acquisitions). The six properties had, at acquisition, a combined fair value of $292,500, with the Company’s partner’s interest valued at $234,000. The Company paid total cash consideration of approximately $120,600, using available cash on hand and proceeds from its unsecured revolving line of credit, before transaction costs and prorations and after assumption of the joint venture’s in-place mortgage financing on those properties of $141,698 at a weighted average interest rate of 4.79%. The properties acquired have a combined total gross leasable area of 1,194,800 square feet. The Company accounted for this transaction as a business combination achieved in stages and recognized a gain on change in control of investment properties of $24,158 in the second quarter of 2014 as a result of remeasuring the carrying value of its 20% interest in the six acquired properties to fair value. Such gain is presented as “Gain on change in control of investment properties” in the accompanying condensed consolidated statements of operations and other comprehensive income. Refer to Note 10 for additional transaction details.
	On February 27, 2014, the Company acquired a 100% interest in Heritage Square, a 53,100 square foot multi-tenant retail property located in Issaquah, Washington, for a purchase price of $18,022 using proceeds from its unsecured revolving line of credit. In addition, on February 27, 2014, the Company paid $10,350 using available cash on hand to acquire the fee interest in Bed Bath & Beyond Plaza, one of the Company’s existing consolidated multi-tenant retail operating properties located in Miami, Florida that was previously subject to a ground lease with a third party. The Company did not acquire any properties during the six months ended June 30, 2013.
	The following table summarizes the acquisition date fair values, before prorations, the Company recorded in conjunction with the acquisitions discussed above:


	Land		$	112,804

	Net assets acquired (b)		$	185,543


	(a)	Includes mortgage premium of $4,787.

	(b)	Net assets attributable to the MS Inland acquisitions are presented at 100%.
	Transaction costs, which were not material, were expensed as incurred and included within “General and administrative expenses” in the accompanying condensed consolidated statements of operations and other comprehensive income. In conjunction with the Bed Bath & Beyond Plaza transaction, the Company reversed a straight-line ground rent liability of $4,258, which is presented in “Gain on extinguishment of other liabilities” in the accompanying condensed consolidated statements of operations and other comprehensive income.

	(a)	Aggregate proceeds are net of transaction costs and exclude $11 of condemnation proceeds, which did not result in any additional gain recognition.

	(b)	The terms of the disposition of Beachway Plaza and Cornerstone Plaza were negotiated as a single transaction.

	(c)	The Company repaid the $30,124 mortgage payable prior to the disposition of the property.

	(d)	The Company repaid the $6,435 mortgage payable prior to the disposition of the property.
	During the year ended December 31, 2013, the Company sold 20 properties, four of which were sold during the six months ended June 30, 2013. The dispositions and certain additional transactions, including earnouts and pad sales, resulted in aggregate proceeds, net of transaction costs, of $38,961 with aggregate gains of $9,587 during the six months ended June 30, 2013.
	As of June 30, 2014, the Company had entered into a contract to sell Greenwich Center, a 182,600 square foot multi-tenant retail property located in Phillipsburg, New Jersey. This property qualified for held for sale accounting treatment upon meeting all applicable GAAP criteria on or prior to June 30, 2014, at which time depreciation and amortization were ceased. As such, the assets and liabilities associated with this property are separately classified as held for sale in the condensed consolidated balance sheet as of June 30, 2014. However, the anticipated disposition of Greenwich Center did not qualify for discontinued operations treatment due to the Company’s early adoption of the revised discontinued operations pronouncement, and, therefore, the operations for all periods presented continue to be classified within continuing operations in the condensed consolidated statements of operations and other comprehensive income. Riverpark Phase IIA, which was sold on March 11, 2014, was classified as held for sale as of December 31, 2013.
	The following table presents the assets and liabilities associated with the held for sale properties:

	(a)	Includes $8,230 and $8,337 of variable rate mortgage debt that was swapped to a fixed rate as of June 30, 2014 and December 31, 2013, respectively, and excludes mortgages payable of $14,475 and $6,435 associated with investment properties classified as held for sale as of June 30, 2014 and December 31, 2013, respectively. The fixed rate mortgages had interest rates ranging from 3.35% to 8.00% and 3.50% to 8.00% as of June 30, 2014 and December 31, 2013, respectively.

	(b)	The variable rate construction loan bears interest at a floating rate of London Interbank Offered Rate (LIBOR) plus 2.25%.
	Mortgages Payable
	During the six months ended June 30, 2014, the Company made mortgages payable repayments in the total amount of $81,106 (excluding scheduled principal payments of $7,983 related to amortizing loans). The loans repaid during the six months ended June 30, 2014 had fixed interest rates with a weighted average interest rate of 6.16%. In addition, during the six months ended June 30, 2014, as part of the MS Inland acquisitions, the Company assumed the joint venture’s in-place mortgage financing on the acquired properties of $141,698 at a weighted average interest rate of 4.79%.
	The majority of the Company’s mortgages payable require monthly payments of principal and interest, as well as reserves for real estate taxes and certain other costs. The Company’s properties and the related tenant leases are pledged as collateral for the fixed rate mortgages payable while a consolidated joint venture property and the related tenant leases are pledged as collateral for the variable rate construction loan. Although the mortgage loans obtained by the Company are generally non-recourse, occasionally, the Company may guarantee all or a portion of the debt on a full-recourse basis. As of June 30, 2014, the Company had guaranteed $7,763 of the outstanding mortgage and construction loans with maturity dates ranging from November 2, 2014 through September 30, 2016 (see Note 15). At times, the Company has borrowed funds financed as part of a cross-collateralized package, with cross-default provisions, in order to enhance the financial benefits of a transaction. In those circumstances, one or more of the properties may secure the debt of another of the Company’s properties. As of June 30, 2014, the most significant cross-collateralized mortgage loan was the IW JV 2009, LLC mortgage in the amount of $478,974, which is cross-collateralized by 55 properties.

	On May 13, 2013, the Company entered into its third amended and restated unsecured credit agreement with a syndicate of financial institutions led by KeyBank National Association and Wells Fargo Securities LLC to provide for an unsecured credit facility aggregating to $1,000,000. The third amended and restated credit facility consists of a $550,000 unsecured revolving line of credit and a $450,000 unsecured term loan (collectively, the credit facility). The Company has the ability to increase available borrowings up to $1,450,000 in certain circumstances. The Company has a one year extension option on the unsecured revolving line of credit, which it may exercise as long as it is in compliance with the terms of the unsecured credit agreement and it pays an extension fee equal to 0.15% of the commitment amount being extended.
	The credit facility is currently priced on a leverage grid at a rate of LIBOR plus a margin ranging from 1.50% to 2.05%, plus a quarterly unused fee ranging from 0.25% to 0.30% depending on the undrawn amount, for the unsecured revolving line of credit and LIBOR plus a margin ranging from 1.45% to 2.00% for the unsecured term loan. On January 27, 2014, the Company received an investment grade credit rating. In accordance with the unsecured credit agreement, the Company may elect to convert to an investment grade pricing grid. Upon making such an election and depending on the Company’s credit rating, the interest rate for the unsecured revolving line of credit would equal LIBOR plus a margin ranging from 0.90% to 1.70%, plus a facility fee ranging from 0.15% to 0.35%, and for the unsecured term loan, LIBOR plus a margin ranging from 1.05% to 2.05%.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

The Company’s objective in using interest rate derivatives is to manage its exposure to interest rate movements and add stability to interest expense. To accomplish this objective, the Company uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed rate payments over the life of the agreement without exchange of the underlying notional amount.

The Company utilizes two interest rate swaps to hedge the variable cash flows associated with variable rate debt. The effective portion of changes in the fair value of derivatives that are designated and that qualify as cash flow hedges is recorded in “Accumulated other comprehensive loss” and is subsequently reclassified to interest expense as interest payments are made on the Company’s variable rate debt. Over the next 12 months, the Company estimates that an additional $1,063 will be reclassified as an increase to interest expense. The ineffective portion of the change in fair value of derivatives is recognized directly in earnings.

The following table summarizes the Company’s interest rate swaps that were designated as cash flow hedges of interest rate risk:

	(a)	The MS Inland joint venture was formed with a large state pension fund; the Company was the managing member of the venture and earned fees for providing property management and leasing services. The Company had the ability to exercise significant influence, but did not have financial or operating control over this joint venture, and as a result the Company accounted for its investment pursuant to the equity method of accounting. On June 5, 2014, the Company dissolved its joint venture arrangement with its partner in MS Inland through the acquisition of the six properties owned by the joint venture.

	(b)	Oak Property & Casualty LLC (the Captive) is an insurance association owned by the Company and four other unaffiliated parties. The Captive was formed to insure/reimburse the members’ deductible obligations for property and general liability insurance claims subject to certain limitations. The Company entered into the Captive to stabilize insurance costs, manage exposures and recoup expenses through the function of the Captive. It has been determined that the Captive is a variable interest entity, but because the Company does not hold the power to most significantly impact the Captive’s performance, the Company is not considered the primary beneficiary. Accordingly, the Company’s investment in the Captive is accounted for pursuant to the equity method of accounting. The Company’s risk of loss is limited to its investment and the Company is not required to fund additional capital to the Captive.
	Under the equity method of accounting, the Company’s net equity investment in each unconsolidated joint venture is reflected in the accompanying condensed consolidated balance sheets and the Company’s share of net income or loss from each unconsolidated joint venture is reflected in the accompanying condensed consolidated statements of operations and other comprehensive income. Distributions from these investments that are related to income from operations are included as operating activities and distributions that are related to capital transactions are included as investing activities in the accompanying condensed consolidated statements of cash flows.
	Combined condensed financial information of the Company’s joint ventures (at 100%) for the periods attributable to the Company’s ownership is summarized as follows:

(a)	On October 1, 2013, the Company dissolved its joint venture arrangement with its partner in RC Inland L.P. (RioCan).

(b)	During 2013, the Company dissolved its joint venture arrangement with its partner in Hampton Retail Colorado, L.L.C. (Hampton).

(c)	On June 5, 2014, the Company dissolved its joint venture arrangement with its partner in MS Inland.

(d)	Included within “(Loss) income from discontinued operations” are the following: property-level operating results attributable to the five properties the Company acquired from its RioCan unconsolidated joint venture on October 1, 2013; all property-level operating results attributable to the Hampton unconsolidated joint venture; and, the property-level operating results recognized by the Company’s MS Inland unconsolidated joint venture related to a property sold to the Company’s RioCan unconsolidated joint venture. The property-level operating results for the entire portfolio of properties held by the Company’s MS Inland unconsolidated joint venture are presented within “(Loss) income from continuing operations” above given that the Company’s acquisition of its partner’s entire 80% interest in all of the properties was a transaction among partners rather than at the venture level. The property-level operating results of the eight RioCan properties in which the Company’s partner acquired the Company’s 20% interest are presented within “(Loss) income from continuing operations” above given the continuity of the controlling financial interest before and after the dissolution transaction.

(a)	On June 5, 2014, the Company dissolved its joint venture arrangement with its partner in MS Inland.

(b)	During the three and six months ended June 30, 2013, Hampton determined that the carrying value of certain of its assets was not recoverable and, accordingly, recorded property level impairment charges in the amounts of $64 and $298, of which the Company’s share was $62 and$286, respectively. The joint venture’s estimate of fair value relating to these impairment assessments was based upon bona fide purchase offers. During 2013, the Company dissolved its joint venture arrangement with its partner in Hampton.

(c)	On October 1, 2013, the Company dissolved its joint venture arrangement with its partner in RioCan.
In addition to the Company’s share of net income (loss) for each unconsolidated joint venture, amortization of basis differences is recorded within “Equity in loss of unconsolidated joint ventures, net” in the condensed consolidated statements of operations and other comprehensive income. Such basis differences resulted from the differences between the Company’s historical cost net book values and the fair values of investment properties contributed to its unconsolidated joint ventures and are amortized over the depreciable lives of the joint ventures’ real estate assets and liabilities. The Company recorded amortization of $45 and $14, which was accretive to net income, related to these differences during the three months ended June 30, 2014 and 2013, respectively. The Company recorded amortization of $115 and $23, which was accretive to net income, related to these differences during the six months ended June 30, 2014 and 2013, respectively.
The Company’s investments in unconsolidated joint ventures are reviewed for potential impairment, in addition to impairment evaluations of the individual assets underlying these investments, whenever events or changes in circumstances warrant such an evaluation. To determine whether impairment, if any, is other-than-temporary, the Company considers whether it has the ability and intent to hold the investment until the carrying value is fully recovered. As a result of such evaluations, impairment charges of $134 and $1,834 were recorded during the three and six months ended June 30, 2013, respectively, to write down the carrying value of the Company’s investment in Hampton. The Company’s Hampton joint venture arrangement was dissolved during the year ended December 31, 2013. No impairment charges to the Company’s investments in unconsolidated joint ventures were considered necessary during the six months ended June 30, 2014.
Acquisitions
On June 5, 2014, the Company dissolved its joint venture arrangement with its partner in MS Inland by acquiring its partner’s 80% ownership interest in the six multi-tenant retail properties owned by the joint venture (see Note 3). The six properties had, at acquisition, a combined fair value of $292,500, with the Company’s partner’s interest valued at $234,000. The Company paid total cash consideration of approximately $120,600 before transaction costs and prorations and after assumption of the joint venture’s in-place mortgage financing on those properties of $141,698 at a weighted average interest rate of 4.79%. The Company accounted for this transaction as a business combination achieved in stages and recognized a gain on change in control of investment properties of $24,158 in the second quarter of 2014 as a result of remeasuring the carrying value of its 20% interest in the six acquired properties to fair value. The following table summarizes the calculation of the gain on change in control of investment properties recognized in conjunction with the transaction discussed above:


Fair value of the net assets acquired at 100%		$	150,802


Fair value of the net assets acquired at 20%		30,160

Impairment or Disposal of Tangible Assets Disclosure [Abstract]

Provision for Impairment of Investment Properties

As of June 30, 2014, the Company identified certain indicators of impairment for eight of its properties, one of which was classified as held for sale as of June 30, 2014. Such indicators included a low occupancy rate, difficulty in leasing space and related cost of re-leasing, financially troubled tenants or reduced anticipated holding periods. The Company performed individual cash flow analyses for this population of properties as of June 30, 2014 and recorded an impairment charge to write down the carrying value of its investment in one property to its estimated fair value. For the remaining six properties, the Company determined that the projected undiscounted cash flows based upon the estimated holding period for each asset exceeded its respective carrying value by a weighted average of 22%. In addition, on March 31, 2014, the Company recorded an impairment charge to write down the carrying value of its investment in one additional property, which was sold on April 1, 2014.

The investment property impairment charges recorded by the Company during the six months ended June 30, 2014 are summarized below:

	Fair Value of Financial Instruments
	The following table presents the carrying value and estimated fair value of the Company’s financial instruments.

	The carrying values of mortgages payable, net and unsecured notes payable in the table above are included in the condensed consolidated balance sheets under the indicated captions. The carrying value of the credit facility is comprised of the “Unsecured term loan” and the “Unsecured revolving line of credit” and the carrying value of the derivative liability is included in “Other liabilities” in the condensed consolidated balance sheets.
	Recurring Fair Value Measurements
	The following table presents the Company’s financial instruments, which are measured at fair value on a recurring basis, by the level in the fair value hierarchy within which those measurements fall. Methods and assumptions used to estimate the fair value of these instruments are described after the table.


		Level 1			Level 2			Level 3			Total
	June 30, 2014
	Derivative liability	$	—		$	892		$	—		$	892


	December 31, 2013
	Derivative liability	$	—		$	751		$	—		$	751

	Derivative liability: The fair value of the derivative liability is determined using a discounted cash flow analysis on the expected future cash flows of each derivative. This analysis utilizes observable market data including forward yield curves and implied volatilities to determine the market’s expectation of the future cash flows of the variable component. The fixed and variable components of the derivative are then discounted using calculated discount factors developed based on the LIBOR swap rate and are aggregated to arrive at a single valuation for the period. The Company also incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of June 30, 2014 and December 31, 2013, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation. As a result, the Company has determined that its derivative valuations in their entirety are classified within Level 2 of the fair value hierarchy. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered any applicable credit enhancements. The Company’s derivative instruments are further described in Note 9.
	Nonrecurring Fair Value Measurements
	The following table presents the Company’s assets measured on a nonrecurring basis at June 30, 2014 and December 31, 2013, aggregated by the level within the fair value hierarchy in which those measurements fall. The table includes information related to properties remeasured to fair value during the six months ended June 30, 2014 and year ended December 31, 2013, except for those properties sold prior to June 30, 2014 and December 31, 2013, respectively. Methods and assumptions used to estimate the fair value of these assets are described after the table.

The estimated fair value of Aon Hewitt East Campus of $18,000 was based upon a bona fide purchase offer received by the Company from an unaffiliated third party (a Level 3 input). A change in the Company’s estimated holding period was the primary driver of the impairment charges recorded to the Company’s investments in Four Peaks Plaza and Lake Mead Crossing. The estimated fair values of Four Peaks Plaza and Lake Mead Crossing of $14,000 and $43,000, respectively, were determined using the income approach. The income approach involves discounting the estimated income stream and reversion (presumed sale) value for a property over an estimated holding period to a present value at a risk-adjusted rate. Discount rates, growth assumptions and terminal capitalization rates utilized in this approach are derived from property-specific information, market transactions and other financial and industry data. The terminal capitalization rate and discount rate are significant inputs to this valuation. The following are the key Level 3 inputs used in estimating the fair value of Four Peaks Plaza and Lake Mead Crossing as of December 31, 2013.


			2013
			Low	High
	Rental growth rates		Varies (i)	Varies (i)
	Operating expense growth rates		3.27%	3.56%
	Discount rates		7.29%	8.45%
	Terminal capitalization rates		6.79%	8.49%

	(i)	Since cash flow models are established at the tenant level, projected rental revenue growth rates fluctuate over the course of the estimated holding period based upon the timing of lease rollover, amount of available space and other property and space-specific factors.
	Fair Value Disclosures
	The following table presents the Company’s financial liabilities, which are measured at fair value for disclosure purposes, by the level in the fair value hierarchy within which they fall. Methods and assumptions used to estimate the fair value of these instruments are described after the table.

Mortgages payable, net: The Company estimates the fair value of its mortgages payable by discounting the future cash flows of each instrument at rates currently offered to the Company by its lenders for similar debt instruments of comparable maturities. The rates used are not directly observable in the marketplace and judgment is used in determining the appropriate rate for each of the Company’s individual mortgages payable based upon the specific terms of the agreement, including the term to maturity, the quality and nature of the underlying property, and its leverage ratio. The rates used range from 2.4% to 6.2% and 2.4% to 5.6% at June 30, 2014 and December 31, 2013, respectively.
Unsecured notes payable: The Company estimates the fair value of its unsecured notes payable by discounting the future cash flows at rates currently offered to the Company by its lenders for comparable instruments. The rates are not directly observable in the marketplace and judgment is used in determining the appropriate rates. The Company used a weighted average discount rate of 4.24% as of June 30, 2014.
Credit facility: The Company estimates the fair value of its credit facility by discounting the future cash flows related to the credit spreads at rates currently offered to the Company by its lenders for comparable facilities. The rates used are not directly observable in the marketplace and judgment is used in determining the appropriate rates. The Company used discount rates of 1.35% and 1.40% for the unsecured term loan and unsecured revolving line of credit, respectively, as of both June 30, 2014 and December 31, 2013.
There were no transfers of liabilities between the levels of the fair value hierarchy during the six months ended June 30, 2014.

	Litigation
	As previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013, in 2012, certain shareholders of the Company filed putative class action lawsuits against the Company and certain of its officers and directors.
	On June 10, 2014, the U.S. District Court in the Northern District of Illinois (the Court) dismissed four of the five lawsuits with prejudice and entered judgment in favor of the Company and its officers and directors. The plaintiffs did not file a timely appeal in these four cases and, consequently, they are now closed. The Court dismissed the fifth lawsuit without prejudice and granted the plaintiff in that case permission to file an amended complaint. The amended complaint does not name the Company or its officers and directors as defendants.
	The Company is subject, from time to time, to various legal proceedings and claims that arise in the ordinary course of business. While the resolution of such matters cannot be predicted with certainty, management believes, based on currently available information, that the final outcome of such matters will not have a material effect on the financial statements of the Company.

	Recent Accounting Pronouncements
	Effective January 1, 2014, companies are required to present unrecognized tax benefits as a reduction to deferred tax assets when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. To the extent none of these are available at the reporting date, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The adoption of this pronouncement did not have any effect on the Company’s condensed consolidated financial statements.
	Effective January 1, 2015, with early adoption permitted effective January 1, 2014, the definition of discontinued operations has been revised to limit what qualifies for this classification and presentation to disposals of components of a company that represent strategic shifts that have, or will have, a major effect on a company’s operations and financial results. Required expanded disclosures for disposals or disposal groups that qualify for discontinued operations are intended to provide users of financial statements with enhanced information about the assets, liabilities, revenues and expenses of such discontinued operations. In addition, in accordance with this pronouncement, companies are required to disclose the pretax profit or loss of an individually significant component that does not qualify for discontinued operations treatment. While the threshold for a disposal or disposal group to qualify for discontinued operations treatment has been revised, this pronouncement retains the held for sale classification and presentation concepts of previous authoritative literature. Accordingly, under this pronouncement, a disposal or disposal group may qualify for held for sale classification but not meet the threshold for discontinued operations treatment. The Company has elected to early adopt this pronouncement effective January 1, 2014. The adoption, which is applied prospectively, is anticipated to substantially reduce the number of the Company’s transactions, going forward, that qualify for discontinued operations as compared to historical results. Upon adoption of this pronouncement effective January 1, 2014, the investment properties that were sold or held for sale during 2014, except for Riverpark Phase IIA, which qualified for discontinued operations treatment under the previous standard, did not qualify for discontinued operations and, as such, are reflected in continuing operations on the condensed consolidated statements of operations and other comprehensive income.
	Effective January 1, 2016, with early adoption permitted effective January 1, 2014, companies that grant their employees share-based payments in which the terms of the award provide that a performance target which affects vesting could be achieved after the requisite service period will be required to treat that feature as a performance condition. The Company has elected to early adopt this pronouncement effective January 1, 2014. The adoption of this pronouncement did not have any effect on the Company’s condensed consolidated financial statements.
	Effective January 1, 2017, companies will be required to apply a five-step model in accounting for revenue arising from contracts with customers. The core principle of the revised revenue model is that a company recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Lease contracts will be excluded from this revenue recognition criteria; however, the sale of real estate will be required to follow the new model. Expanded quantitative and qualitative disclosures regarding revenue recognition will be required for contracts that are subject to this guidance. The Company does not expect the adoption will have a material effect on its consolidated financial statements, however it will continue to evaluate this assessment until the guidance becomes effective.

	(a)	The MS Inland joint venture was formed with a large state pension fund; the Company was the managing member of the venture and earned fees for providing property management and leasing services. The Company had the ability to exercise significant influence, but did not have financial or operating control over this joint venture, and as a result the Company accounted for its investment pursuant to the equity method of accounting. On June 5, 2014, the Company dissolved its joint venture arrangement with its partner in MS Inland through the acquisition of the six properties owned by the joint venture.

	(b)	Oak Property & Casualty LLC (the Captive) is an insurance association owned by the Company and four other unaffiliated parties. The Captive was formed to insure/reimburse the members’ deductible obligations for property and general liability insurance claims subject to certain limitations. The Company entered into the Captive to stabilize insurance costs, manage exposures and recoup expenses through the function of the Captive. It has been determined that the Captive is a variable interest entity, but because the Company does not hold the power to most significantly impact the Captive’s performance, the Company is not considered the primary beneficiary. Accordingly, the Company’s investment in the Captive is accounted for pursuant to the equity method of accounting. The Company’s risk of loss is limited to its investment and the Company is not required to fund additional capital to the Captive.

(a)	On October 1, 2013, the Company dissolved its joint venture arrangement with its partner in RC Inland L.P. (RioCan).

(b)	During 2013, the Company dissolved its joint venture arrangement with its partner in Hampton Retail Colorado, L.L.C. (Hampton).

(c)	On June 5, 2014, the Company dissolved its joint venture arrangement with its partner in MS Inland.

(d)	Included within “(Loss) income from discontinued operations” are the following: property-level operating results attributable to the five properties the Company acquired from its RioCan unconsolidated joint venture on October 1, 2013; all property-level operating results attributable to the Hampton unconsolidated joint venture; and, the property-level operating results recognized by the Company’s MS Inland unconsolidated joint venture related to a property sold to the Company’s RioCan unconsolidated joint venture. The property-level operating results for the entire portfolio of properties held by the Company’s MS Inland unconsolidated joint venture are presented within “(Loss) income from continuing operations” above given that the Company’s acquisition of its partner’s entire 80% interest in all of the properties was a transaction among partners rather than at the venture level. The property-level operating results of the eight RioCan properties in which the Company’s partner acquired the Company’s 20% interest are presented within “(Loss) income from continuing operations” above given the continuity of the controlling financial interest before and after the dissolution transaction.

	(a)	Includes impairment charges to write down the carrying value of the Company’s Gloucester Town Center investment property to estimated fair value. The estimated fair value of Gloucester Town Center of $10,500 was based upon a bona fide purchase offer received by the Company from an unaffiliated third party (a Level 3 input).

	(b)	Includes impairment charges to write down the carrying value of the Company’s Aon Hewitt East Campus, Four Peaks Plaza and Lake Mead Crossing investment properties to estimated fair value. The estimated fair value of Aon Hewitt East Campus of $18,000 was based upon a bona fide purchase offer received by the Company from an unaffiliated third party (a Level 3 input). A change in the Company’s estimated holding period was the primary driver of the impairment charges recorded to the Company’s investments in Four Peaks Plaza and Lake Mead Crossing. The estimated fair values of Four Peaks Plaza and Lake Mead Crossing of $14,000 and $43,000, respectively, were determined using the income approach. The income approach involves discounting the estimated income stream and reversion (presumed sale) value for a property over an estimated holding period to a present value at a risk-adjusted rate. Discount rates, growth assumptions and terminal capitalization rates utilized in this approach are derived from property-specific information, market transactions and other financial and industry data. The terminal capitalization rate and discount rate are significant inputs to this valuation. The following are the key Level 3 inputs used in estimating the fair value of Four Peaks Plaza and Lake Mead Crossing as of December 31, 2013.


			2013
			Low	High
	Rental growth rates		Varies (i)	Varies (i)
	Operating expense growth rates		3.27%	3.56%
	Discount rates		7.29%	8.45%
	Terminal capitalization rates		6.79%	8.49%

	(i)	Since cash flow models are established at the tenant level, projected rental revenue growth rates fluctuate over the course of the estimated holding period based upon the timing of lease rollover, amount of available space and other property and space-specific factors.

The MS Inland joint venture was formed with a large state pension fund; the Company was the managing member of the venture and earned fees for providing property management and leasing services. The Company had the ability to exercise significant influence, but did not have financial or operating control over this joint venture, and as a result the Company accounted for its investment pursuant to the equity method of accounting. On June 5, 2014, the Company dissolved its joint venture arrangement with its partner in MS Inland through the acquisition of the six properties owned by the joint venture.

[2]

Oak PropertyB & CasualtyB LLC (the Captive) is an insurance association owned by the Company and four other unaffiliated parties. The Captive was formed to insure/reimburse the membersb deductible obligations for property and general liability insurance claims subject to certain limitations. The Company entered into the Captive to stabilize insurance costs, manage exposures and recoup expenses through the function of the Captive. It has been determined that the Captive is a variable interest entity, but because the Company does not hold the power to most significantly impact the Captivebs performance, the Company is not considered the primary beneficiary. Accordingly, the Companybs investment in the Captive is accounted for pursuant to the equity method of accounting. The Companybs risk of loss is limited to its investment and the Company is not required to fund additional capital to the Captive.

[3]

On June 5, 2014, the Company dissolved its joint venture arrangement with its partner in MS Inland.

[4]

During the three and six months ended JuneB 30, 2013, Hampton determined that the carrying value of certain of its assets was not recoverable and, accordingly, recorded property level impairment charges in the amounts of $64 and $298, of which the Companybs share was $62 and$286, respectively. The joint venturebs estimate of fair value relating to these impairment assessments was based upon bona fide purchase offers. During 2013, the Company dissolved its joint venture arrangement with its partner in Hampton.

[5]

On October 1, 2013, the Company dissolved its joint venture arrangement with its partner in RioCan.

Includes impairment charges to write down the carrying value of the Companybs Gloucester Town Center investment property to estimated fair value. The estimated fair value of Gloucester Town Center of $10,500 was based upon a bona fide purchase offer received by the Company from an unaffiliated third party (a Level 3 input).

[2]

Includes impairment charges to write down the carrying value of the Companybs Aon Hewitt East Campus, Four Peaks Plaza and Lake Mead Crossing investment properties to estimated fair value. The estimated fair value of Aon Hewitt East Campus of $18,000 was based upon a bona fide purchase offer received by the Company from an unaffiliated third party (a Level 3 input). A change in the Companybs estimated holding period was the primary driver of the impairment charges recorded to the Companybs investments in Four Peaks Plaza and Lake Mead Crossing. The estimated fair values of Four Peaks Plaza and Lake Mead Crossing of $14,000 and $43,000, respectively, were determined using the income approach. The income approach involves discounting the estimated income stream and reversion (presumed sale) value for a property over an estimated holding period to a present value at a risk-adjusted rate. Discount rates, growth assumptions and terminal capitalization rates utilized in this approach are derived from property-specific information, market transactions and other financial and industry data. The terminal capitalization rate and discount rate are significant inputs to this valuation. The following are the key Level 3 inputs used in estimating the fair value of Four Peaks Plaza and Lake Mead Crossing as of December 31, 2013. 2013 LowB HighRental growth ratesB Varies (i)B Varies (i)Operating expense growth ratesB 3.27%B 3.56%Discount ratesB 7.29%B 8.45%Terminal capitalization ratesB 6.79%B 8.49%(i)Since cash flow models are established at the tenant level, projected rental revenue growth rates fluctuate over the course of the estimated holding period based upon the timing of lease rollover, amount of available space and other property and space-specific factors.
