	Organization
	Inland American Real Estate Trust, Inc. (the “Company”) was formed on October 4, 2004 (inception) to acquire and manage a diversified portfolio of commercial real estate, primarily retail, office, industrial, multi-family (both conventional and student housing), and lodging properties, located in the United States. On March 12, 2014, the Company began the process of becoming fully self-managed by terminating its business management agreement, hiring all of its business manager's employees, and acquiring the assets of its business manager necessary to perform the functions previously performed by the business manager. The Company is executing on a long-term portfolio strategy to focus specifically on the retail, lodging, and student housing asset classes.
	The accompanying 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) and limited partnerships (LPs). The effects of all significant intercompany transactions have been eliminated.
	Each property is owned by a separate legal entity which maintains its own books and financial records and each entity's assets are not available to satisfy the liabilities of other affiliated entities, except as otherwise disclosed in Debt Note 8.
	At March 31, 2014, the Company owned a portfolio of 272 properties, in which the operating activity is reflected in continuing operations on the consolidated statements of operations and comprehensive income for the three months ended March 31, 2014 and 2013. Additionally, at March 31, 2014, the Company classified ten properties as held for sale, in which the operating activity is reflected in discontinued operations on the consolidated statements of operations and comprehensive income for the three months ended March 31, 2014 and 2013. Comparatively, at March 31, 2013, the Company owned 759 properties, and there were no properties classified as held for sale.
	The breakdown by segment of the 272 owned properties at March 31, 2014 is as follows:
	Segment	Property Count	Square Feet / Rooms / Beds
	Retail	117	16,885,919	Square feet

	Summary of Significant Accounting Policies
	Discontinued Operations
	In April 2014, the FASB issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which includes amendments that change the requirements for reporting discontinued operations and require additional disclosures about discontinued operations. Under the new guidance, only disposals representing a strategic shift that has (or will have) a major effect on the entity’s results and operations would qualify as discontinued operations. In addition, the ASU 2014-08 expands the disclosure requirements for disposals that meet the definition of a discontinued operation and requires entities to disclose information about disposals of individually significant components that do not meet the definition of discontinued operations.  ASU 2014-08 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2014. The Company has elected to early adopt ASU 2014-08, effective January 1, 2014. For the quarter ended March 31, 2014, the operations reflected in discontinued operations are only related to the net lease assets that were classified as held for sale at December 31, 2013. All other asset disposals are now included as a component of income from continuing operations.
	Refer to the Company’s 2013 Form 10-K for a summary of significant accounting policies.

	Consolidated Entities
	The Company has ownership interests of 67% in various limited liability companies which own nine shopping centers. These nine shopping centers are considered held for sale as of March 31, 2014. The assets and liabilities associated with these nine shopping centers are classified separately as held for sale on the consolidated balance sheets for the most recent reporting period. The operations for the periods presented are classified on the consolidated statements of operations and comprehensive income as discontinued operations for all periods presented. These entities are considered variable interest entities (“VIEs”) as defined in ASC 810, and the Company is considered the primary beneficiary of each of these entities. Therefore, these entities are consolidated by the Company. The entities' agreements contain put/call provisions which grant the right to the outside owners and the Company to require these entities to redeem the ownership interests of the outside owners during future periods. Because the outside ownership interests are subject to a put/call arrangement requiring settlement for a fixed amount, these entities are treated as 100% owned subsidiaries by the Company with the amount of $47,762 as of March 31, 2014 reflected as a financing and included within other liabilities classified as held for sale in the accompanying consolidated financial statements. Interest expense is recorded on these liabilities in an amount generally equal to the preferred return due to the outside owners as provided in the entities' agreements.
	During the fourth quarter 2013, the Company entered into two joint ventures to each develop a lodging property. The Company has ownership interests of 75% in each joint venture. These entities are considered VIEs as defined in FASB ASC 810. The Company determined that it has the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, as well as the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. As such, the Company has a controlling financial interest and is considered the primary beneficiary of each of these entities. Therefore, these entities are consolidated by the Company.
	For the VIEs where the Company is the primary beneficiary, the following are the liabilities of the consolidated VIEs which are not recourse to the Company, and the assets that can be used only to settle those obligations.

	Transactions with Related Parties
	On March 12, 2014, the Company entered into a series of agreements and amendments to existing agreements with affiliates of The Inland Group, Inc. (the "Inland Group") pursuant to which the Company began the process of becoming entirely self-managed (collectively, the "Self-Management Transactions"). On March 12, 2014, as part of the Self-Management Transactions, the Company; the Company's business manager, Inland American Business Manager & Advisor, Inc. (the “Business Manager”); Inland American Lodging Advisor, Inc. a wholly owned subsidiary of the Business Manager ("ILodge"); the Company's property managers, Inland American Industrial Management LLC (“Inland Industrial”), Inland American Office Management LLC (“Inland Office”) and Inland American Retail Management LLC (“Inland Retail”); their parent, Inland American Holdco Management LLC (“Holdco” and collectively with Inland Industrial, Inland Office and Inland Retail, the “Property Managers”); and Eagle I Financial Corp. ("Eagle"), entered into a Master Modification Agreement (the “Master Modification Agreement”) pursuant to which the Company agreed with the Business Manager to terminate the management agreement with the Business Manager, hire all of the Business Manager’s employees and acquired the assets or rights necessary to conduct the functions previously performed for the Company by the Business Manager. The Company also hired certain Property Manager employees and assumed responsibility for performing significant property management activities. The Company assumed certain limited liabilities of the Business Manager and the Property Managers, including accrued liabilities for employee holiday, sick and vacation time for those Business Manager, ILodge and Property Manager employees who became employees of the Company and liabilities arising after the closing of the Master Modification Agreement under leases and contracts assigned to the Company. The Company did not assume, and the Business Manager is obligated to indemnify the Company against, any liabilities related to the pre-closing operations of the Business Manager. Eagle, an indirect wholly owned subsidiary of the Inland Group, has guaranteed the Business Manager’s indemnity and other obligations under the Master Modification Agreement. The Company did not pay an internalization fee or self-management fee in connection with the Master Modification Agreement but reimbursed the Business Manager and Property Managers for specified transaction related expenses and employee payroll costs. The Company entered into a consulting agreement with Inland Group affiliates for a term of three months at $200 per month, which the Company has the right to extend month-to-month if consulting services are still required.
	Concurrently, as part of the Self-Management Transactions, the Company entered into an Asset Acquisition Agreement (the "Asset Acquisition Agreement") with the Property Managers and Eagle, pursuant to which the Company has agreed to terminate the management agreements with the Property Managers at the end of 2014, hire the remaining Property Manager employees and acquire the assets or rights necessary to conduct the remaining functions performed for the Company by the Property Managers. The Company agreed to assume certain limited liabilities, including accrued liabilities for employee holiday, sick and vacation time for Property Manager employees that become Company employees and liabilities arising after the closing of the Asset Acquisition Agreement under leases and other contracts that the Company decides to assume in the transaction. The Company will not assume any liabilities related to the pre-closing operations of the Property Managers, and it will not pay an internalization fee or self-management fee in connection with the Asset Acquisition Agreement. The Asset Acquisition Agreement contains termination rights and closing conditions for both the Company and the Property Managers, and the Company expect to consummate the transactions contemplated thereby on December 31, 2014.
	Also on March 12, 2014, as part of the Self-Management Transactions, the Company entered into separate Amended and Restated Master Management Agreements (collectively, the “Amended Property Management Agreements”) with each of the Property Managers (excluding Holdco), pursuant to which the Property Managers will continue to provide property management services to the Company through December 31, 2014, other than the property-level accounting, lease administration, leasing, marketing and construction functions that we began performing pursuant to the Master Modification Agreement.
	The following table summarizes the Company’s related party transactions for the three months ended March 31, 2014 and 2013.

	(a)	In connection with the closing of the Master Modification Agreement and termination of the business management agreement, on March 31, 2014, the Company reimbursed the Business Manager for compensation and other ordinary course out-of-pocket expenses, which totaled approximately $3,401. In addition, the Company reimbursed the Property Managers approximately $249 for compensation and out-of-pocket expenses incurred between January 1, 2014 and closing for the Property Manager employees the Company hired at closing to approximate the economics as though the Company had hired such employees on January 1, 2014. These costs are reflected in general and administrative reimbursements above.
	In addition, the Company has directly retained affiliates of the Business Manager to provide the information technology, investor services and other back-office services that were provided to the Company through the Business Manager prior to the termination of the business management agreement. The terms of these service agreements remain the same in all material respects and are generally terminable without penalty by either party upon 60 days’ notice. These costs are reflected in general and administrative reimbursements above.
	Unpaid amounts as of March 31, 2014 and December 31, 2013 are included in accounts payable and accrued expenses on the consolidated balance sheets.
	(b)	The Company pays Inland Investment Advisors, Inc., a related party of the Business Manager, to purchase and monitor its investment in marketable securities.
	(c)	As part of the Self-Management Transactions, select property management fees charged to the Company were reduced effective January 1, 2014 to reflect, among other things, the hiring of the Property Manager employees and the services that were no longer being performed by the Property Managers. The Amended Property Management Agreements reduced the property management fees charged in respect of most of the Company’s multi-tenant retail properties from 4.50% of gross income generated by the applicable property to 3.50% for the first six months of 2014 and to 3.25% for the last six months of 2014, and reduced fees charged in respect of the Company’s multi-tenant office properties from 3.75% of gross income generated by the applicable property to 3.50% for the first six months of 2014 and to 3.25% for the last six months of 2014. The Company also agreed to assume responsibility for the compensation-related expenses of the Property Manager employees hired by the Company effective March 1, 2014.
	For the three months ended March 31, 2013, the property managers, entities owned principally by individuals who were related parties of the Business Manager, were entitled to receive property management fees by property type, as follows: (i) for any bank branch facility (office or retail), 2.50% of the gross income generated by the property; (ii) for any multi-tenant industrial property, 4.00% of the gross income generated by the property; (iii) for any multi-family property, 3.75% of the gross income generated by the property; (iv) for any multi-tenant office property, 3.75% of the gross income generated by the property; (v) for any multi-tenant retail property, 4.50% of the gross income generated by the property; (vi) for any single-tenant industrial property, 2.25% of the gross income generated by the property; (vii) for any single-tenant office property, 2.90% of the gross income generated by the property; and (viii) for any single-tenant retail property, 2.90% of the gross income generated by the property.
	In addition to these fees, the property managers receive reimbursements of payroll costs for property level employees. The Company reimbursed or will reimburse the property managers and other affiliates $2,391 and $3,007 for the three months ended March 31, 2014 and 2013, respectively.
	(d)	In connection with the closing of the Master Modification Agreement and termination of the business management agreement, the Company paid a business management fee for January 2014, which totaled approximately $3,333. The Company did not pay a business management fee for February or March 2014. Pursuant to the letter agreement dated May 4, 2012, the business management fee shall be reduced for investigation costs exclusive of legal fees incurred in conjunction with the SEC matter. During the three months ended March 31, 2014, the Company incurred $739 of investigation costs, resulting in a business management fee expense of $2,594 for the three months ended March 31, 2014. Pursuant to the March 12, 2014 self-management transactions, the May 4, 2012 letter agreement by the Business Manager has been terminated.
	The Company incurred a business management fee $9,972 for the three months ended March 31, 2013. After the Company’s stockholders received a non-cumulative, non-compounded return of 5.00% per annum on their “invested capital,” the Company paid its Business Manager an annual business management fee of up to 1.00% of the “average invested assets,” payable quarterly in an amount equal to 0.25% of the average invested assets as of the last day of the immediately preceding quarter. For the three months ended March 31, 2013, average invested assets were $11,423,146. The business management fee was equal to 0.09% of average invested assets for the three months ended March 31, 2013, respectively.
	(e)	The Company pays a related party of the Business Manager 0.2% of the principal amount of each loan placed for the Company. Such costs are capitalized as loan fees and amortized over the respective loan term.
	As of March 31, 2014 and December 31, 2013, the Company had deposited $376 and $376, respectively, in Inland Bank and Trust, a subsidiary of Inland Bancorp, Inc., an affiliate of The Inland Real Estate Group, Inc.
	The Company is party to an agreement with an LLC formed as an insurance association captive (the “Captive”), which is wholly-owned by the Company and three related parties, Inland Real Estate Corporation (“IRC”), Inland Diversified Real Estate Trust, Inc., and Inland Real Estate Income Trust, Inc., and a third party, Retail Properties of America ("RPAI"). The Company paid insurance premiums of $3,210 and $3,175 for the three months ended March 31, 2014 and 2013, respectively.
	In addition, the Company held 899,820 shares of IRC valued at $9,493 as of March 31, 2014. As of December 31, 2013, the Company held 899,820 shares of IRC valued at $9,466.

	Investment in Marketable Securities
	Investment in marketable securities of $253,026 and $242,819 at March 31, 2014 and December 31, 2013, respectively, consists primarily of preferred and common stock investments in other REITs and certain real estate related bonds which are classified as available-for-sale securities and recorded at fair value. The cost basis net of impairments of available-for-sale securities was $171,128 and $171,450 as of March 31, 2014 and December 31, 2013, respectively.
	Unrealized holding gains and losses on available-for-sale securities are excluded from earnings and reported as a separate component of comprehensive income until realized. The Company has net accumulated other comprehensive income related to its marketable securities portfolio of $81,898 and $71,369, which includes gross unrealized losses of $1,657 and $3,189 related to its marketable securities as of March 31, 2014 and December 31, 2013, respectively. Securities with gross unrealized losses have a related fair value of $13,783 as of March 31, 2014.
	The Company’s policy for assessing recoverability of its available-for-sale securities is to record a charge against net earnings when the Company determines that a decline in the fair value of a security drops below the cost basis and believes that decline to be other-than-temporary. Factors in the assessment of other-than-temporary impairment include determining whether (1) the Company has the ability and intent to hold the security until it recovers, and (2) the length of time and degree to which the security’s price has declined. No impairment to available-for-sale securities was recorded for the three months ended March 31, 2014 and 2013.
	Dividend income is recognized when earned. During the three months ended March 31, 2014 and 2013, dividend income of $3,200 and $4,595, respectively, was recognized and is included in interest and dividend income on the consolidated statements of operations and comprehensive income.

	The Company is negotiating refinancing debt maturing in 2014 with various lenders at terms that will allow us to pay comparable interest rates. It is anticipated that the Company will be able to repay, refinance or extend the debt maturing in 2014, and the Company believes it has adequate sources of funds to meet short term cash needs related to these refinancings. Of the total outstanding debt for all years, approximately $242,037 is recourse to the Company.
	Some of the mortgage loans require compliance with certain covenants, such as debt coverage service ratios, investment restrictions and distribution limitations. As of March 31, 2014, the Company was in compliance with all mortgage loan requirements except five loans with a carrying value of $105,910; none of which are cross collateralized with any other mortgage loans or recourse to the Company. The stated maturities of the mortgage loans in default are reflected as follows: $12,100 in 2011, $20,115 in 2016, and $73,695 in 2017.
	Line of Credit
	In 2013, the Company entered into a credit agreement with KeyBank National Association, JP Morgan Chase Bank National Association and other financial institutions to provide for a senior unsecured credit facility in the aggregate amount of $500,000. The credit facility consists of a $300,000 senior unsecured revolving line of credit and the total outstanding term loan is $200,000. The Company's accordion feature is $800,000. The senior unsecured revolving line of credit matures on May 7, 2016 and the unsecured term loan matures on May 7, 2017. The Company has a one year extension option on the revolver which it may exercise as long as there is no existing default, it is in compliance with all covenants, a 60-day notice has been provided and it pays an extension fee equal to 0.20% of the commitment amount being extended.
	As of March 31, 2014, management believes the Company was in compliance with all of the covenants and default provisions under the credit agreement. As of March 31, 2014, the interest rates of the revolving line of credit and unsecured term loan were 1.60% and 1.66%, respectively. Upon closing the credit agreement, the Company borrowed the full amount of the term loan which remains outstanding as of March 31, 2014.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Fair Value Measurements
	In accordance with ASC 820, Fair Value Measurement and Disclosures, the Company defines fair value based on the price that would be received upon sale of an asset or the exit price that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company uses a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value. The fair value hierarchy consists of three broad levels, which are described below:
	•	Level 1 - Quoted prices in active markets for identical assets or liabilities that the entity has the ability to access.
	•	Level 2 - Observable inputs, other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.
	•	Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.
	The Company has estimated the fair value of its financial and non-financial instruments using available market information and valuation methodologies the Company believes to be appropriate for these purposes. Considerable judgment and a high degree of subjectivity are involved in developing these estimates and, accordingly, they are not necessarily indicative of amounts that would be realized upon disposition.
	Recurring Measurements
	For assets and liabilities measured at fair value on a recurring basis, quantitative disclosure of the fair value for each major category of assets and liabilities is presented below:
			Fair Value Measurements at March 31, 2014

	Derivative interest rate instruments		$	—			$	(458	)		$	—
	Total liabilities		$	—			$	(458	)		$	—
	Level 1
	At March 31, 2014 and December 31, 2013, the fair value of the available for sale real estate equity securities have been valued based upon quoted market prices for the same or similar issues when current quoted market prices are available. Unrealized gains or losses on investment are reflected in unrealized gain (loss) on investment securities in comprehensive income on the consolidated statements of operations and comprehensive income.
	Level 2
	To calculate the fair value of the real estate related bonds and the derivative interest rate instruments, the Company primarily uses quoted prices for similar securities and contracts. For the real estate related bonds, the Company reviews price histories for similar market transactions. For the derivative interest rate instruments, the Company uses inputs based on data that is observed in the forward yield curve which is widely observable in the marketplace.  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 which utilizes Level 3 inputs, such as estimates of current credit spreads. However, as of March 31, 2014 and December 31, 2013, the Company has assessed that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. As of March 31, 2014 and December 31, 2013, the Company had entered into interest rate swap agreements with a notional value of $106,790 and $60,044 , respectively.
	Level 3
	At March 31, 2014 and December 31, 2013, the Company had no level three recurring fair value measurements.
	Non-Recurring Measurements
	The following table summarizes activity for the Company’s assets measured at fair value on a non-recurring basis. The Company recognized certain impairment charges to reflect the investments at their fair values for the three months ended March 31, 2014 and 2013. The asset groups that were reflected at fair value through this evaluation are:

	During the three months ended March 31, 2014, the Company identified certain properties which may have a reduction in the expected holding period and reviewed the probability of these assets' dispositions. The Company’s estimated fair value relating to the investment properties’ impairment analysis was based on a comparison of letters of intent or purchase contracts, broker opinions of value and ten-year discounted cash flow models, which includes contractual inflows and outflows over a specific holding period. The cash flows consist of unobservable inputs such as contractual revenues and forecasted revenues and expenses. These unobservable inputs are based on market conditions and the Company’s expected growth rates. For those properties impaired during the three months ended March 31, 2014, the Company estimated fair value using letters of intent and purchase contracts.During the three months ended March 31, 2013, capitalization rates ranging from 6.75% to 10.00% and discount rates ranging from 8.50% to 11.50% were utilized in the model and are based upon observable rates that the Company believes to be within a reasonable range of current market rates.
	For the three months ended March 31, 2014 and 2013, the Company recorded an impairment of investment properties of $9,839 and $9,456, respectively. Certain properties have been disposed and were impaired prior to disposition and the related impairment charge of $0 and $4,476 are included in discontinued operations for the three months ended March 31, 2014 and 2013, respectively.

	Income Taxes
	The Company has elected and has operated so as to qualify to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended, commencing with the tax year ended December 31, 2005. So long as it qualifies as a REIT, the Company generally will not be subject to federal income tax on taxable income that is distributed to stockholders. A REIT is subject to a number of organizational and operational requirements including a requirement that it currently distribute at least 90% of its REIT taxable income (subject to certain adjustments) to its stockholders (the “90% Distribution Test”). If the Company fails to qualify as a REIT in any taxable year, without the benefit of certain relief provisions, the Company will be subject to federal and state 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 federal income and excise taxes on its undistributed income. In addition, the Company owns substantially all of the outstanding stock of a subsidiary REIT, MB REIT (Florida), Inc. (“MB REIT”), which the Company consolidates for financial reporting purposes but which is treated as a separate REIT for federal income tax purposes.
	The Company has identified certain distribution and stockholder reimbursement practices that may have caused certain dividends to be treated as preferential dividends, which cannot be used to satisfy the 90% Distribution Requirement. The Company has also identified the ownership of certain assets that may have violated a REIT qualification requirement that prohibits a REIT from owning "securities" of any one issuer in excess of 5% of the REIT's total assets at the end of any calendar quarter (the "5% Securities Test"). In order to provide greater certainty with respect to the Company's qualification as a REIT for federal income tax purposes, management concluded that it was in the best interest of the Company and its stockholders to request closing agreements from the Internal Revenue Service ("IRS") for both the Company and MB REIT with respect to such matters. Accordingly, on October 31, 2012, MB REIT filed a request for a closing agreement with the IRS. Additionally, the Company filed a separate request for a closing agreement on its own behalf on March 7, 2013.
	The Company identified certain aspects of the calculation of certain dividends on MB REIT's preferred stock and also aspects of the operation of certain "set aside" provisions with respect to accrued but unpaid dividends on certain classes of MB REIT's preferred stock that may have caused certain dividends to be treated as preferential dividends. In the case of the Company, management identified certain aspects of the operation of the Company's dividend reinvestment plan and distribution procedures and also certain reimbursements of stockholder expenses that may have caused certain dividends to be treated as preferential dividends. If these practices resulted in preferential dividends, the Company and MB REIT would not have satisfied the 90% Distribution Requirement and thus may not have qualified as REITs, which would result in substantial corporate tax liability for the years in which the Company or MB REIT failed to qualify as a REIT.
	In addition, the Company and MB REIT made certain overnight investments in bank commercial paper. While the Internal Revenue Code does not provide a specific definition of “cash item”, the Company believes that overnight commercial paper should be treated as a “cash item”, which is not treated as a “security” for purposes of the 5% Securities Test. If treated as a "security", the bank commercial paper would appear to have represented more than 5% of the Company's and MB REIT's total assets at the end of certain calendar quarters. In the event this commercial paper is treated as a "security", the Company anticipates that it would be required to pay corporate income tax on the income earned with respect to the portion of the commercial paper that violated the 5% Securities Test.
	The Company can provide no assurance that the IRS will accept the Company's or MB REIT's closing agreement requests. Even if the IRS accepts those requests, the Company and MB REIT may be required to pay a penalty. The Company cannot predict whether such a penalty would be imposed or, if so, the amount of the penalty. The Company believes that (i) the IRS will enter into closing agreements with the Company and MB REIT and (ii) the business manager may be liable, in whole or in part, for any penalty imposed in connection with those closing agreements. As noted above, the Company can provide no assurance that the IRS will enter into closing agreements with the Company and MB REIT or that the Company and MB REIT will not be liable for any penalty imposed in connection with those closing agreements. Management believes based on the currently available information, that such penalty, if any, will not have a material adverse effect on the financial statements of the Company.
	The Company has elected to treat certain of its consolidated subsidiaries, and may in the future elect to treat newly formed subsidiaries, as taxable REIT subsidiaries pursuant to the Internal Revenue Code. Taxable REIT subsidiaries may participate in non-real estate related activities and/or perform non-customary services for tenants and are subject to federal and state income tax at regular corporate tax rates. The Company's hotels are leased to certain of the Company's taxable REIT subsidiaries. Lease revenue from these taxable REIT subsidiaries and its wholly-owned subsidiaries is eliminated in consolidation. For the three months ended March 31, 2014 and 2013, an income tax expense of $2,221 and $2,030 was included on the consolidated statements of operations and comprehensive income.

	The Company's long-term portfolio strategy is to focus on three asset classes - retail, lodging, and student housing. During the three months ended March 31, 2014, the Company has continued to execute on this strategy by disposing of 223 non-strategic assets as well as classifying ten non-strategic assets as held for sale.  In 2013, the Company restated their business segments. Net operating income for the three months ended March 31, 2013 has been restated to reflect these changes in business segments. All non-strategic assets have been included in the non-core segment. The non-core segment includes office properties, industrial properties, bank branches, retail single tenant properties, and conventional multi-family properties. The Company has concentrated its efforts on driving portfolio growth in the multi-tenant retail, student housing and lodging segments to enhance the long-term value of each segment's portfolio and respective platforms. For its non-core properties, the Company strives to improve individual property performance to increase each property’s value. The Company evaluates segment performance primarily based on net operating income. Net operating income of the segments exclude interest expense, depreciation and amortization, general and administrative expenses, net income of noncontrolling interest and other investment income from corporate investments. The non-segmented assets primarily include the Company’s cash and cash equivalents, investment in marketable securities, construction in progress, investment in unconsolidated entities and notes receivable.
	For the three months ended March 31, 2014, approximately 14% of the Company’s rental revenue, included in the non-core segment, was generated by three properties leased to AT&T, Inc. As a result of the concentration of revenue generated from these properties, if AT&T were to cease paying rent or fulfilling its other monetary obligations, the Company could have significantly reduced rental revenues or higher expenses until the defaults were cured or the properties were leased to a new tenant or tenants.
	The following table summarizes net property operations income by segment as of and for the three months ended March 31, 2014.

	Certain leases and operating agreements within the lodging segment require the Company to reserve funds relating to replacements and renewals of the hotels' furniture, fixtures and equipment. As of March 31, 2014 the Company has funded $77,013 in reserves for future improvements. This amount is included in restricted cash and escrows on the consolidated balance sheet as of March 31, 2014.
	The SEC is conducting a non-public, formal, fact-finding investigation ("SEC Investigation") to determine whether there have been violations of certain provisions of the federal securities laws regarding the Company's business manager fees, property management fees, transactions with its affiliates, timing and amount of distributions paid to its investors, determination of property impairments, and any decision regarding whether it might become a self-administered REIT. The Company has not been accused of any wrongdoing by the SEC. The Company has also been informed by the SEC that the existence of this investigation does not mean that the SEC has concluded that anyone has broken the law or that the SEC has a negative opinion of any person, entity, or security. The Company has been cooperating fully with the SEC.
	The Company cannot reasonably estimate the timing of the investigation, nor can it predict whether or not the investigation might have a material adverse effect on its business.
	The Company also received related demands (“Derivative Demands”) by stockholders to conduct investigations regarding claims that the officers, the board of directors, the former business manager, and affiliates of the former business manager (the “Inland American Parties”) breached its fiduciary duties to Company in connection with the matters that the Company disclosed are subject to the SEC Investigation. The first Derivative Demand claims that the Inland American Parties (i) falsely reported the value of its common stock until September 2010; (ii) caused it to purchase shares of common stock from stockholders at prices in excess of its value; and (iii) disguised returns of capital paid to stockholders as REIT income, resulting in the payment of fees to the former business manager for which it was not entitled. The three stockholders in that demand contend that legal proceedings should seek recovery of damages in an unspecified amount allegedly sustained by it. The second Derivative Demand by another shareholder makes similar claims and further alleges that the Inland American Parties (i) caused it to engage in transactions that unduly favored related parties, (ii) falsely disclosed the timing and amount of distributions, and (iii) falsely disclosed whether the Company might become a self-administered REIT. The Company also received a letter from another stockholder that fully adopts and joins in the first Derivative Demand, but makes no additional demands on the Company to perform investigation or pursue claims.
	Upon receiving the first of the Derivative Demands, the full board of directors responded by authorizing the independent directors to investigate the claims contained in the first Derivative Demand, any subsequent stockholder demands, as well as any other matters the independent directors see fit to investigate, including matters related to the SEC Investigation. Pursuant to this authority, the independent directors have formed a special litigation committee that is comprised solely of independent directors to review and evaluate the matters referred by the full Board to the independent directors, and to recommend to the full Board any further action as is appropriate. The special litigation committee is investigating these claims with the assistance of independent legal counsel and will make a recommendation to the Board of Directors after the committee has completed its investigation.
	On March 21, 2013, counsel for the stockholders who made the first Derivative Demand filed a derivative lawsuit in the Circuit Court of Cook County, Illinois, on behalf of the Company. The case has been stayed pending completion of the special litigation committee's investigation. The Company cannot predict the timing of the special litigation committee investigation or the Derivative Demands, nor can the Company predict whether or not the special litigation committee investigation or Derivative Demands might have a material adverse impact on its business.
	On April 26, 2013, two stockholders of the Company filed a putative class action in the United States District Court for the Northern District of Illinois against the Company, and current members and one former member of its board of directors ("the Defendants"). The complaint sought damages on behalf of plaintiffs and similarly situated individuals who purchased additional shares in the Company pursuant to the Company's Distribution Reinvestment Plan ("DRP") on or after March 30, 2009. Plaintiffs allege that the Defendants breached its fiduciary duties to plaintiffs and to members of the putative class by inflating the yearly estimated share price announced by the Company and by selling shares in the DRP to plaintiffs and members of the putative class at those allegedly inflated prices. On November 18, 2013, the class action was dismissed with prejudice for failing to state a claim that would entitle the plaintiffs to relief. The Court disagreed with the plaintiffs' allegations, noting in its memorandum opinion and order that the Company’s public disclosures fully described the manner in which the board estimated share value for the Company’s stock sold through the DRP. The Court entered judgment in favor of the Defendants. The plaintiffs appealed the judgment. As of February 26, 2014, the parties entered into a settlement agreement whereby the plaintiffs agreed to dismiss their appeal in exchange for a cash settlement from the Company. The Company believes that the amount of the settlement is not material and is less than the amount the Defendants would have incurred in defending the appeal.

	In accordance with GAAP, the Company classifies properties as held for sale when certain criteria are met. On the day that the criteria are met, the Company suspends depreciation on the properties held for sale, including depreciation for tenant improvements and additions, as well as the amortization of acquired in-place leases. The assets and liabilities associated with those investment properties that are held for sale are classified separately on the consolidated balance sheets for the most recent reporting period and recorded at the lesser of the carrying value or fair value less costs to sell. At September 30, 2013, these assets were recorded at their carrying value. The operations for the periods presented are classified on the consolidated statements of operations and comprehensive income as discontinued operations for all periods presented.
	On August 8, 2013, we entered into a purchase agreement to sell our net lease assets, consisting of 294 retail, office, and industrial properties in an all-cash transaction valued at approximately $2.3 billion. In accordance with the terms of the purchase agreement, the buyer elected to “kick-out” of the transaction 13 properties valued at approximately $180.1 million, leaving the remaining properties to be classified as held for sale. Excluding the “kicked out” properties, the transaction is valued at approximately $2.1 billion. Of these remaining properties, the Company has sold 271, with the remaining ten properties meeting the criteria to be classified as held for sale as of March 31, 2014. As of March 31, 2013, there were no properties classified as held for sale.

	On May 1, 2014, the Company announced the final results of its modified "Dutch Auction" tender offer ("Offer") for the purchase price of up to $350,000 in value of shares of its common stock, which expired on April 25, 2014. In accordance with rules promulgated by the Securities and Exchange Commission, the Company had the option to increase the number of shares accepted for payment in the Offer by up to 2% of the outstanding shares without amending or extending the Offer. To avoid any proration to the stockholders that tendered shares, the Company decided to increase the number of shares accepted for payment in the Offer. The Company accepted for purchase 60,665,233.238 shares of its common stock at a purchase price (without brokerage commissions) of $6.50 per share, for an aggregate cost of approximately $394,300, excluding fees and expenses relating to the tender offer and paid by the Company. The tendering stockholders also received monthly distributions in respect of their shares during the time they were stockholders. The 60,665,233.238 shares accepted for purchase in the Offer represent approximately 6.61% of the Company’s currently issued and outstanding shares of common stock. Tendering stockholders are not entitled to any distributions with a record date after the expiration date of the Offer. Subsequent to the final purchase of approved Offer shares, the final number of shares repurchased, allowing for corrections, was 60,663,070.430 on April 30, 2014.
	The Company's paying agent will promptly issue payment for shares validly tendered and accepted for purchase in accordance with the terms and conditions of the Offer. Shares tendered and not accepted for purchase will be returned promptly to stockholders. As a result of the settlement of the Offer, the Company has approximately 856,491,123 shares outstanding as of May 8, 2014.
	On May 8, 2014, the Company disposed of nine non-core net lease assets for a gross disposition price of $98,300. These assets were classified as held for sale as of March 31, 2014. These assets represent the final transaction between the Company and the purchaser of the net lease portfolio transaction sale. In addition, the purchaser terminated the purchase agreement solely with respect to the equity interests in a subsidiary owning a net lease asset with a disposal price of $228,400, and in connection with such termination, purchaser paid to the Company $10,000 of the deposit posted into escrow. The purchaser has no material relationship with the Company and the sale is not an affiliated transaction. As of March 31, 2014, the assets and liabilities relating to this asset continue to be classified as held for sale while the operations have been reclassified as continuing operations in accordance with ASC 205. This asset will be re-measured during second quarter 2014.

	(a)	In connection with the closing of the Master Modification Agreement and termination of the business management agreement, on March 31, 2014, the Company reimbursed the Business Manager for compensation and other ordinary course out-of-pocket expenses, which totaled approximately $3,401. In addition, the Company reimbursed the Property Managers approximately $249 for compensation and out-of-pocket expenses incurred between January 1, 2014 and closing for the Property Manager employees the Company hired at closing to approximate the economics as though the Company had hired such employees on January 1, 2014. These costs are reflected in general and administrative reimbursements above.
	In addition, the Company has directly retained affiliates of the Business Manager to provide the information technology, investor services and other back-office services that were provided to the Company through the Business Manager prior to the termination of the business management agreement. The terms of these service agreements remain the same in all material respects and are generally terminable without penalty by either party upon 60 days’ notice. These costs are reflected in general and administrative reimbursements above.
	Unpaid amounts as of March 31, 2014 and December 31, 2013 are included in accounts payable and accrued expenses on the consolidated balance sheets.
	(b)	The Company pays Inland Investment Advisors, Inc., a related party of the Business Manager, to purchase and monitor its investment in marketable securities.
	(c)	As part of the Self-Management Transactions, select property management fees charged to the Company were reduced effective January 1, 2014 to reflect, among other things, the hiring of the Property Manager employees and the services that were no longer being performed by the Property Managers. The Amended Property Management Agreements reduced the property management fees charged in respect of most of the Company’s multi-tenant retail properties from 4.50% of gross income generated by the applicable property to 3.50% for the first six months of 2014 and to 3.25% for the last six months of 2014, and reduced fees charged in respect of the Company’s multi-tenant office properties from 3.75% of gross income generated by the applicable property to 3.50% for the first six months of 2014 and to 3.25% for the last six months of 2014. The Company also agreed to assume responsibility for the compensation-related expenses of the Property Manager employees hired by the Company effective March 1, 2014.
	For the three months ended March 31, 2013, the property managers, entities owned principally by individuals who were related parties of the Business Manager, were entitled to receive property management fees by property type, as follows: (i) for any bank branch facility (office or retail), 2.50% of the gross income generated by the property; (ii) for any multi-tenant industrial property, 4.00% of the gross income generated by the property; (iii) for any multi-family property, 3.75% of the gross income generated by the property; (iv) for any multi-tenant office property, 3.75% of the gross income generated by the property; (v) for any multi-tenant retail property, 4.50% of the gross income generated by the property; (vi) for any single-tenant industrial property, 2.25% of the gross income generated by the property; (vii) for any single-tenant office property, 2.90% of the gross income generated by the property; and (viii) for any single-tenant retail property, 2.90% of the gross income generated by the property.
	In addition to these fees, the property managers receive reimbursements of payroll costs for property level employees. The Company reimbursed or will reimburse the property managers and other affiliates $2,391 and $3,007 for the three months ended March 31, 2014 and 2013, respectively.
	(d)	In connection with the closing of the Master Modification Agreement and termination of the business management agreement, the Company paid a business management fee for January 2014, which totaled approximately $3,333. The Company did not pay a business management fee for February or March 2014. Pursuant to the letter agreement dated May 4, 2012, the business management fee shall be reduced for investigation costs exclusive of legal fees incurred in conjunction with the SEC matter. During the three months ended March 31, 2014, the Company incurred $739 of investigation costs, resulting in a business management fee expense of $2,594 for the three months ended March 31, 2014. Pursuant to the March 12, 2014 self-management transactions, the May 4, 2012 letter agreement by the Business Manager has been terminated.
	The Company incurred a business management fee $9,972 for the three months ended March 31, 2013. After the Company’s stockholders received a non-cumulative, non-compounded return of 5.00% per annum on their “invested capital,” the Company paid its Business Manager an annual business management fee of up to 1.00% of the “average invested assets,” payable quarterly in an amount equal to 0.25% of the average invested assets as of the last day of the immediately preceding quarter. For the three months ended March 31, 2013, average invested assets were $11,423,146. The business management fee was equal to 0.09% of average invested assets for the three months ended March 31, 2013, respectively.
	(e)	The Company pays a related party of the Business Manager 0.2% of the principal amount of each loan placed for the Company. Such costs are capitalized as loan fees and amortized over the respective loan term.
