LEXINGTON REALTY TRUST AND CONSOLIDATED SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2013 and 2012

(Unaudited and dollars in thousands, except share/unit and per share/unit data)

(1) The Company and Financial Statement Presentation

Lexington Realty Trust (the “Company”) is a self-managed and self-administered Maryland statutory real estate investment trust (“REIT”) that invests in and acquires, owns, finances and manages a geographically diversified portfolio of predominately single-tenant office, industrial and retail properties. The Company also provides investment advisory and asset management services to investors in the single-tenant area. As of June 30, 2013, the Company had equity ownership interests in approximately 215 consolidated properties in 41 states. A majority of the real properties in which the Company has an equity ownership interest are generally subject to net or similar leases where the tenant bears all or substantially all of the cost, including cost increases, for real estate taxes, insurance, utilities and ordinary maintenance of the property. However, certain leases provide that the landlord is responsible for certain or all operating expenses. In addition, we acquire, originate and hold investments in loan assets related to single-tenant real estate.

The Company believes it has qualified as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). Accordingly, the Company will not be subject to federal income tax, provided that distributions to its shareholders equal at least the amount of its REIT taxable income as defined under the Code. The Company is permitted to participate in certain activities in order to maintain its qualification as a REIT, so long as these activities are conducted in entities which elect to be treated as taxable REIT subsidiaries (“TRS”) under the Code. As such, the TRS are subject to federal income taxes on the income from these activities.

The Company conducts its operations either directly or indirectly through (1) property owner subsidiaries and lender subsidiaries, (2) operating partnerships in which the Company is the sole unit holder of the general partner and the sole unit holder of the limited partner that holds a majority of the limited partner interests (“OP units”), (3) a wholly-owned TRS, or (4) investments in joint ventures. Property owner subsidiaries are landlords under leases for properties in which the Company has an interest and/or borrowers under loan agreements secured by properties in which the Company has an investment and lender subsidiaries are lenders under loan agreements where the Company made an investment in a loan asset, but in all cases are separate and distinct legal entities.

Basis of Presentation and Consolidation. The Company's unaudited condensed consolidated financial statements are prepared on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles (“GAAP”). The financial statements reflect the accounts of the Company and its consolidated subsidiaries. The Company consolidates its wholly-owned subsidiaries and its partnerships and joint ventures which it controls (1) through voting rights or similar rights or (2) by means other than voting rights if the Company is the primary beneficiary of a variable interest entity ("VIE"). Entities which the Company does not control and entities which are VIEs in which the Company is not the primary beneficiary are accounted for under appropriate GAAP.

The financial statements contained herein have been prepared by the Company in accordance with GAAP for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all information and footnotes required by GAAP for complete financial statements. However, in the opinion of management, the interim financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results of the periods presented. The results of operations for the three and six months ended June 30, 2013 and 2012, are not necessarily indicative of the results that may be expected for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes thereto included in the Company's Form 10-K for the year ended December 31, 2012 filed with the SEC on February 25, 2013 (“Annual Report”).

Use of Estimates. Management has made a number of significant estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses to prepare these unaudited condensed consolidated financial statements in conformity with GAAP. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. The current economic environment has increased the degree of uncertainty inherent in these estimates and assumptions. Management adjusts such estimates when facts and circumstances dictate. The most significant estimates made include the recoverability of accounts receivable, the allocation of property purchase price to tangible and intangible assets acquired and liabilities assumed, the determination of VIEs and which entities should be consolidated, the

determination of impairment of long-lived assets, loans receivable and equity method investments, the valuation of derivative financial instruments and the useful lives of long-lived assets. Actual results could differ materially from those estimates.

Fair Value Measurements. The Company follows the guidance in the Financial Accounting Standards Board Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures, as amended (“Topic 820”), to determine the fair value of financial and non-financial instruments. Topic 820 defines fair value, establishes a framework for measuring fair value in GAAP and expands disclosures about fair value measurements. Topic 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 - quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities; Level 2 - observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 - unobservable inputs, which are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as considering counterparty credit risk. The Company has formally elected to apply the portfolio exception within Topic 820 with respect to measuring counterparty risk for all of its derivative transactions subject to master netting arrangements.

Acquisition, Development and Construction Arrangements. The Company evaluates loans receivable where the Company participates in residual profits through loan provisions or other contracts to ascertain whether the Company has the same risks and rewards as an owner or a joint venture partner. Where the Company concludes that such arrangements are more appropriately treated as an investment in real estate, the Company reflects such loan receivable as an equity investment in real estate under construction in the unaudited condensed consolidated balance sheets. In these cases, no interest income is recorded on the loan receivable and the Company records capitalized interest during the construction period. In arrangements where the Company engages a developer to construct a property or provides funds to a tenant to develop a property, the Company will capitalize the funds provided to the developer/tenant and internal costs of interest and real estate taxes, if applicable, during the construction period.

Reclassifications. Certain amounts included in the 2012 unaudited condensed consolidated financial statements have been reclassified, primarily relating to discontinued operations, to conform to the 2013 presentation.

Recently Issued Accounting Guidance. In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-02: Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, to improve the transparency of reporting the reclassifications of significant amounts out of accumulated other comprehensive income. This guidance requires entities to present the effects on the line items of net income of significant reclasses from accumulated other comprehensive income, either where net income is presented or in the notes, as well as cross-reference to other disclosures currently required under GAAP for other reclassification items (that are not required under GAAP) to be reclassified directly to net income in their entirety in the same reporting period. The new disclosure requirements are effective for annual reporting periods beginning after December 15, 2012. The new disclosures are required for both interim and annual reporting. The implementation of this guidance did not have an impact on the Company's financial position, results of operations or cash flows.

(2) Earnings Per Share

A significant portion of the Company's non-vested share-based payment awards are considered participating securities and as such, the Company is required to use the two-class method for the computation of basic and diluted earnings per share. Under the two-class computation method, net losses are not allocated to participating securities unless the holder of the security has a contractual obligation to share in the losses. The non-vested share-based payment awards are not allocated losses as the awards do not have a contractual obligation to share in losses of the Company.

(1) The Company’s consolidated partnership, which owns the Long Island City, New York property, provided as of June 30, 2013 for the Company to receive distributions of operating cash flows as follows: (1) a 6.3% priority return on its invested capital up to $25,000, (2) an 11% priority return on its invested capital in excess of $25,000 and (3) approximately 50% of any excess return. Subsequent to June 30, 2013, the Company acquired its joint venture partners’ interest in the partnership.

(2) The Company incurred additional initial costs of $3,825 which are included in “Other assets” in the accompanying unaudited condensed consolidated balance sheet.

(3) The Company incurred leasing costs of $323.

The Company recognized aggregate acquisition expenses of $250 and $380 for the six months ended June 30, 2013 and 2012, respectively, which are included as operating expenses within the Company's unaudited condensed consolidated statements of operations.

The Company is engaged in various forms of build-to-suit development activities. The Company, through lender subsidiaries and property owner subsidiaries, may enter into the following acquisition, development and construction arrangements: (1) lend funds to construct build-to-suit projects subject to a single-tenant lease and agree to purchase the properties upon completion of construction and commencement of a single-tenant lease, (2) hire developers to construct built-to-suit projects on owned properties leased to single tenants, (3) fund the construction of build-to-suit projects on owned properties pursuant to the terms in single-tenant lease agreements or (4) enter into purchase and sale agreements with developers to acquire single-tenant build-to-suit properties upon completion.

(1) At June 30, 2013, the Company's commitment could have been terminated by the Company due to an outstanding contingency, thus costs incurred through June 30, 2013 of $1,191 are recognized as pre-development costs and included in “Other assets” in the accompanying unaudited condensed consolidated balance sheet. Subsequent to June 30, 2013, the termination right expired.

The Company has variable interests in certain developer entities constructing the facilities but is not the primary beneficiary of the entities as the Company does not have a controlling financial interest. As of June 30, 2013 and December 31, 2012, the Company's aggregate investment in development arrangements, excluding the Las Vegas, Nevada property, was $23,099 and $65,122, respectively, and are presented as investments in real estate under construction in the accompanying unaudited condensed consolidated balance sheets. The Company capitalized interest of $1,116 and $1,046 during the six months ended June 30, 2013 and 2012, respectively, relating to build-to-suit activities.

In addition, the Company has committed to acquire, upon its completion, an office property in Omaha, Nebraska for $39,125, which is subject to a net lease that will have a 20-year term upon completion. Construction is expected to be completed in the fourth quarter of 2013. The Company can give no assurances that any of these acquisitions under contract or build-to-suit transactions will be consummated.

On September 1, 2012, the Company, together with an operating partnership subsidiary, acquired the remaining common equity interest in Net Lease Strategic Assets Fund L.P. ("NLS") from Inland American (Net Lease) Sub, LLC that the Company did not already own for a cash payment of $9,438 and the assumption of all outstanding liabilities. Immediately prior to the acquisition, the Company owned 15% of NLS's common equity and 100% of NLS's preferred equity. At the date of acquisition, NLS owned 41 properties totaling 5.8 million square feet in 23 states, plus a 40% tenant-in-common interest in an office property.  The Company's investment in NLS had previously been accounted for under the equity method and is now consolidated.

The Company recognized gross revenues from continuing operations of $21,505 and a net loss of $(3,542) from NLS properties during the six months ended June 30, 2013. The Company recognized $9,306 of equity in earnings relating to NLS during the six months ended June 30, 2012.

The following unaudited condensed consolidated pro forma information is presented as if the Company acquired the remaining equity in NLS on January 1, 2012. The information presented below is not necessarily indicative of what the actual results of operations would have been had the transaction been completed on January 1, 2012, nor does it purport to represent the Company's future operations:

In addition, the Company conveyed certain properties along with the respective escrow deposits in satisfaction of an aggregate $49,509 of non-recourse secured mortgage loans and recognized aggregate net gains on debt satisfaction of $9,250. These dispositions resulted in an aggregate gain on sales of properties of $12,806. During the six months ended June 30, 2012, the Company disposed of its interests in certain properties to unrelated third parties for an aggregate gross disposition price of $74,815 and recognized an aggregate gain on sales of properties of $2,671.

The Company assesses on a regular basis whether there are any indicators that the carrying value of its real estate assets may be impaired. Potential indicators may include an increase in vacancy at a property, tenant reduction in utilization of a property, tenant financial instability and the potential sale of the property in the near future. An asset is determined to be impaired if the asset's carrying value is in excess of its estimated fair value. During the six months ended June 30, 2013 and 2012, the Company recognized $8,735 and $5,690, respectively, of impairment charges in discontinued operations, relating to real estate assets that were disposed below their carrying value.

In addition, the Company recognized an impairment charge of $2,413 in continuing operations during the six months ended June 30, 2013. The Company explored the possible disposition of a non-core retail property and determined that the expected undiscounted cash flows based upon a revised estimated holding period of the property was below the current carrying value. Accordingly, the Company reduced the carrying value of this property to its estimated fair value.

(5) Loans Receivable

As of June 30, 2013 and December 31, 2012, the Company's loans receivable, including accrued interest and net of origination fees and loan loss reserves were comprised primarily of first and second mortgage loans and mezzanine loans on real estate aggregating $88,994 and $72,540, respectively. The loans bear interest, including imputed interest, at rates ranging from 4.6% to 20.0% and mature at various dates through 2022.

The following is a summary of our loans receivable as of June 30, 2013 and December 31, 2012:

	Loan carrying-value(1)
Loan		6/30/2013		12/31/2012		Interest Rate		Maturity Date
Norwalk, CT(2)		$	20,262	$	3,479	7.50	%	11/2014
Homestead, FL(3)		8,646		8,036		7.50	%	08/2014
Schaumburg, IL(4)		21,579		21,885		20.00	%	01/2012
Westmont, IL		26,721		26,902		6.45	%	10/2015
Southfield, MI		6,994		7,364		4.55	%	02/2015
Austin, TX		2,206		2,038		16.00	%	10/2018
Other		2,586		2,836		8.00	%	2021-2022
		$	88,994	$	72,540

(1) Loan carrying value includes accrued interest and is net of origination costs and fee eliminations, if any.

(2) The Company is committed to lend up to $32,600.

(3) The Company is committed to lend up to $10,660.

(4) Loan is in default. The Company has obtained a foreclosure judgment but has not foreclosed as of June 30, 2013. The Company did not record interest income of $1,911 and $2,647 during the six months ended June 30, 2013 and the year ended December 31, 2012, respectively. The Company believes the office property collateral has an estimated fair value in excess of the Company's investment.

The Company has two types of financing receivables: loans receivable and a capitalized financing lease. The Company determined that its financing receivables operate within one portfolio segment as they are within the same industry and use the same impairment methodology. The Company's loans receivable are secured by commercial real estate assets and the capitalized financing lease is for a commercial office property located in Greenville, South Carolina. In addition, the Company assesses all financing receivables for impairment, when warranted, based on an individual analysis of each receivable.

The Company's financing receivables operate within one class of financing receivables as these assets are collateralized by commercial real estate and similar metrics are used to monitor the risk and performance of these assets. The Company's management uses credit quality indicators to monitor financing receivables such as quality of collateral, the underlying tenant's credit rating and collection experience. As of June 30, 2013, the financing receivables were performing as anticipated and there were no significant delinquent amounts outstanding, other than the Schaumburg, Illinois loan as disclosed above.

(6) Fair Value Measurements

The following tables present the Company's assets and liabilities from continuing operations measured at fair value on a recurring and non-recurring basis as of June 30, 2013 and December 31, 2012, aggregated by the level in the fair value hierarchy within which those measurements fall:

	Balance		Fair Value Measurements Using
Description	June 30, 2013		(Level 1)		(Level 2)		(Level 3)
Interest rate swap asset	$	3,912	$	—	$	3,912	$	—
Impaired real estate assets*	$	4,277	$	—	$	—	$	4,277

	Balance			Fair Value Measurements Using
Description	December 31, 2012			(Level 1)		(Level 2)			(Level 3)
Interest rate swap liability	$	(6,556	)	$	—	$	(6,556	)	$	—
Impaired real estate assets*	$	3,327		$	—	$	—		$	3,327

*Represents a non-recurring fair value measurement.

The table below sets forth the carrying amounts and estimated fair values of the Company's financial instruments as of June 30, 2013 and December 31, 2012.

	As of June 30, 2013				As of December 31, 2012
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Assets
Loans Receivable	$	88,994	$	78,375	$	72,540	$	61,734
Liabilities
Debt	$	1,778,305	$	1,766,215	$	1,878,208	$	1,835,157

The majority of the inputs used to value the Company's interest rate swaps fall within Level 2 of the fair value hierarchy, such as observable market interest rate curves; however, the credit valuation associated with the interest rate swaps utilizes Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. As of June 30, 2013 and December 31, 2012, the Company determined that the credit valuation adjustment relative to the overall fair value of the interest rate swaps was not significant. As a result, the interest rate swaps have been classified in Level 2 of the fair value hierarchy.

The Company estimates the fair value of its real estate assets by using income and market valuation techniques. The Company may estimate fair values using market information such as broker opinions of value, recent sales data for similar assets or discounted cash flow models, which primarily rely on Level 3 inputs. The cash flow models include estimated cash inflows and outflows over a specified holding period. These cash flows may include contractual rental revenues, projected future rental revenues and expenses and forecasted tenant improvements and lease commissions based upon market conditions determined through discussion with local real estate professionals, experience the Company has with its other owned properties in such markets and expectations for growth. Capitalization rates and discount rates utilized in these models are estimated by management based upon rates that management believes to be within a reasonable range of current market rates for the respective properties based upon an analysis of factors such as property and tenant quality, geographical location and local supply and demand observations. To the extent the Company under estimates forecasted cash outflows (tenant improvements, lease commissions and operating costs) or over estimates forecasted cash inflows (rental revenue rates), the estimated fair value of its real estate assets could be overstated.

The Company estimates the fair values of its loans receivable by using an estimated discounted cash flow analysis using Level 3 inputs consisting of scheduled cash flows and discount rate estimates to approximate those that a willing buyer and seller might use and/or the estimated value of the underlying collateral. The fair value of the Company's debt is estimated by using a discounted cash flow analysis using Level 3 inputs, based upon estimates of market interest rates.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited and dollars in thousands, except share/unit and per share/unit data)

Fair values cannot be determined with precision, may not be substantiated by comparison to quoted prices in active markets and may not be realized upon sale. Additionally, there are inherent uncertainties in any fair value measurement technique, and changes in the underlying assumptions used, including discount rates, liquidity risks and estimates of future cash flows, could significantly affect the fair value measurement amounts.

Cash Equivalents, Restricted Cash, Accounts Receivable and Accounts Payable. The Company estimates that the fair value of cash equivalents, restricted cash, accounts receivable and accounts payable approximates carrying value due to the relatively short maturity of the instruments.

(7) Investment in and Advances to Non-Consolidated Entities

During 2012, the Company formed two joint ventures in which it has a minority interest. One joint venture acquired a 120,000 square foot retail property in Palm Beach Gardens, Florida for $29,750 which was net leased for an approximate 15-year term. The Company had a 36% interest in the venture and provided a $12,000 non-recourse mortgage loan to the venture which was repaid in full in February 2013. The Company received a distribution of $2,557 in March 2013, a portion of which represented a return of capital reducing the Company's ownership interest to 25%.

The second joint venture, in which the Company has a 15% interest, acquired a 100% economic interest in an inpatient rehabilitation hospital in Humble, Texas for $27,750, which was net leased for an approximate 17-year term. The acquisition was partially funded by a non-recourse mortgage with an original principal amount of $15,260, which bears interest at a fixed rate of 4.7% and matures in May 2017.

Pemlex LLC. In July 2012, the Company sold its interest in Pemlex LLC for $13,218 in connection with a restructuring of Pemlex LLC. In addition, the Company (1) entered into a management agreement with the purchaser that provides for a backstop guaranty to a third party who delivered a letter of credit in the amount of $2,500 as security for "bad boy" acts under the purchaser's third-party acquisition financing and (2) agreed to deliver a replacement letter of credit, if necessary, in the amount of $2,500 to the purchaser's lender during the term of the management agreement. No gain or loss was recognized in the transaction as the investment was sold at its cost basis.

Concord Debt Holdings LLC (“Concord”) and CDH CDO LLC ("CDH CDO"). The Company's investments in Concord and CDH CDO were valued at zero and the Company recognized income on the cash basis. During the six months ended June 30, 2012, the Company received aggregate distributions of $885, which were recorded as equity in earnings of non-consolidated entities. During the second quarter of 2012, the Company sold all of its interest in Concord and CDH CDO for $7,000 in cash.

(8) Debt

The Company had outstanding non-recourse secured mortgages and notes payable of $1,043,934 and $1,415,961 as of June 30, 2013 and December 31, 2012, respectively. Interest rates, including imputed rates on mortgages and notes payable, ranged from 3.6% to 8.5% at June 30, 2013 and December 31, 2012 and the mortgages and notes payables mature between 2013 and 2027 as of June 30, 2013. The weighted-average interest rate at June 30, 2013 and December 31, 2012 was 5.4% and 5.6%, respectively.

In June 2013, the Company issued $250,000 aggregate principal amount of 4.25% Senior Notes due 2023 (“Senior Notes”) at an issuance price of 99.026% of the principal amount. The Senior Notes are unsecured, pay interest semi-annually in arrears and mature in June 2023. The Company may redeem the notes at its option at any time prior to maturity in whole or in part by paying the principal amount of the notes being redeemed plus a premium. The Company issued these Senior Notes at an initial discount of $2,435 which will be recognized as additional interest expense over the term of the Senior Notes. The Senior Notes are rated Baa2 and BBB- by Moody’s Investors Service, Inc. (“Moody’s”) and Standard & Poor’s Rating Services (“S&P”), respectively.

On February 12, 2013, the Company refinanced its $300,000 secured revolving credit facility with a $300,000 unsecured revolving credit facility with KeyBank National Association (“KeyBank”), as agent. The unsecured revolving credit facility matures in February 2017 but can be extended until February 2018 at the Company’s option. The unsecured revolving credit facility bore interest at LIBOR plus 1.50% to 2.05% based on the Company’s leverage ratio, as defined

therein. Since the Company has obtained an investment-grade unsecured debt rating from both Moody’s and S&P, the interest rate under the unsecured revolving credit facility ranges from LIBOR plus 0.95% to 1.725% (1.15% as of June 30, 2013) depending on the Company's unsecured debt rating. In addition, the Company increased its availability under the unsecured revolving credit facility from $300,000 to $400,000. At June 30, 2013, the unsecured revolving credit facility had no amounts outstanding, outstanding letters of credit of $7,644 and availability of $392,356, subject to covenant compliance.

In connection with the refinancing discussed above, the Company also procured a five-year $250,000 unsecured term loan facility from KeyBank, as agent. The unsecured term loan matures in February 2018, required regular payments of interest only at interest rates ranging from LIBOR plus 1.45% to 2.00% dependent on the Company's leverage ratio, as defined therein and can be prepaid without penalty. Since the Company has obtained an investment-grade unsecured debt rating from both Moody’s and S&P, the interest rate under the unsecured term loan ranges from LIBOR plus 1.10% to 2.10% (1.35% as of June 30, 2013) depending on the Company’s unsecured debt rating. As of June 30, 2013, the Company entered into an interest-rate swap agreement to fix LIBOR at 0.73% through February 2018 on the $64,000 of outstanding LIBOR-based borrowings.

During 2012, the Company procured a $255,000 secured term loan from Wells Fargo Bank, National Association (“Wells Fargo”), as agent. The term loan matures in January 2019. The term loan required regular payments of interest only at interest rates ranging from LIBOR plus 2.00% to 2.85% dependent on the Company's leverage ratio, as defined therein. Since the Company has obtained an investment-grade unsecured debt rating from both Moody’s and S&P, the interest rate under the secured term loan ranges from LIBOR plus 1.50% to 2.25% (1.75% as of June 30, 2013) depending on the Company's unsecured debt rating. The Company may prepay any outstanding borrowings under the term loan facility at a premium through January 12, 2016 and at par thereafter. During 2012, the Company entered into interest-rate swap agreements to fix LIBOR at a weighted-average rate of 1.42% through January 2019 on the $255,000 of outstanding LIBOR-based borrowings. The term loan was initially secured by ownership interest pledges by certain subsidiaries that collectively owned a borrowing base of properties. In February 2013, the Company amended the term loan to release the collateral as security.

The unsecured revolving credit facility and the unsecured term loans are subject to financial covenants, which the Company was in compliance with at June 30, 2013.

The Company had $25,000 and $35,551 secured term loans with KeyBank, which were satisfied in January 2012 and the Company recognized debt satisfaction charges of $1,578 as a result of the satisfaction.

During 2010, the Company issued $115,000 aggregate principal amount of 6.00% Convertible Guaranteed Notes due 2030. The notes pay interest semi-annually in arrears and mature in January 2030. The holders of the notes may require the Company to repurchase their notes in January 2017, January 2020 and January 2025 for cash equal to 100% of the notes to be repurchased, plus any accrued and unpaid interest. The Company may not redeem any notes prior to January 2017, except to preserve its REIT status. The notes have a current conversion rate of 146.2412 common shares per one thousand principal amount of the notes, representing a conversion price of approximately $6.84 per common share. The conversion rate is subject to adjustment under certain circumstances, including increases in the Company's dividend rate above a certain threshold and the issuance of stock dividends. The notes are convertible by the holders under certain circumstances for cash, common shares or a combination of cash and common shares at the Company's election. The notes are convertible prior to the close of business on the second business day immediately preceding the stated maturity date, at any time beginning in January 2029 and also upon the occurrence of specified events. During the six months ended June 30, 2013, $42,750 aggregate principal amount of the notes were converted for 6,167,111 common shares and aggregate cash payments of $2,663, plus accrued and unpaid interest resulting in aggregate debt satisfaction charges of $10,633.

During 2007, the Company issued an aggregate $450,000 of its 5.45% Exchangeable Guaranteed Notes due 2027. The Company prepaid $387,850 of the notes prior to 2012 and the remaining $62,150 of notes were repurchased by the Company and satisfied in January 2012 pursuant to a holder repurchase option. This resulted in debt satisfaction charges of $44.

(9) Derivatives and Hedging Activities

Risk Management Objective of Using Derivatives. The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the type, amount, sources, and duration of its debt funding and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company's derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company's known or expected cash receipts and its known or expected cash payments principally related to the Company's investments and borrowings.

Cash Flow Hedges of Interest Rate Risk. The Company's objectives in using interest rate derivatives are to add stability to interest expense, to manage its exposure to interest rate movements and therefore manage its cash outflows as it relates to the underlying debt instruments. To accomplish these objectives, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy relating to certain of its variable rate debt instruments. 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 agreements without exchange of the underlying notional amount.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2013 and 2012

(Unaudited and dollars in thousands, except share/unit and per share/unit data)

The Company has designated the interest-rate swap agreements with its counterparties as cash flow hedges of the risk of variability attributable to changes in the LIBOR swap rate on $319,000 of LIBOR-indexed variable-rate unsecured term loans. Accordingly, changes in the fair value of the swaps are recorded in other comprehensive income (loss) and reclassified to earnings as interest becomes receivable or payable. In January 2012, the Company settled the 2008 interest-rate swap agreement with KeyBank for $3,539. The Company had a credit balance of $1,837 in accumulated other comprehensive income at the settlement date which was amortized into earnings on a straight-line basis through February 2013.

Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on the term loans. During the next 12 months, the Company estimates that an additional $3,316 will be reclassified as an increase to interest expense.

As of June 30, 2013, the Company had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk:

Interest Rate Derivative	Number of Instruments	Notional
Interest Rate Swaps	6	$319,000

The Company's agreements with swap derivative counterparties contain provisions whereby if the Company defaults on the underlying indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default of the swap derivative obligation. As of June 30, 2013, the Company has not posted any collateral related to the agreements.

(10) Concentration of Risk

The Company seeks to reduce its operating and leasing risks through the geographic diversification of its properties, tenant industry diversification, avoidance of dependency on a single asset and the creditworthiness of its tenants. For the six months ended June 30, 2013 and 2012, no single tenant represented greater than 10% of rental revenues.

Cash and cash equivalent balances at certain institutions may exceed insurable amounts. The Company believes it mitigates this risk by investing in or through major financial institutions.

(11) Equity

Shareholders' Equity. During the six months ended June 30, 2013 and 2012, the Company issued 690,873 and 563,639 common shares, respectively, under its direct share purchase plan, raising net proceeds of $7,466 and $4,291, respectively.

During the six months ended June 30, 2013, the Company implemented an At-The-Market offering program under which the Company may issue up to $100,000 in common shares over the term of this program. The Company issued 3,409,927 common shares under this program during the six months ended June 30, 2013 and generated aggregate gross proceeds of $36,884. In addition, in March 2013, the Company issued 23,000,000 common shares in a public offering raising gross proceeds of $258,336. The net proceeds from these offerings of $293,934 were used to repay borrowings under the Company's unsecured revolving credit facility and the balance for general corporate purposes, including acquisitions.

The Company issued 1,325,000 non-vested common shares to certain officers with a grant date fair value of $14,098 during the six months ended June 30, 2013. The non-vested common shares are subject to long-term retention non-vested share agreements and vest from 2018 to 2022 in accordance with the agreements. In addition, the Company issued 37,500 fully vested common shares to the non-management members of the Company's Board of Trustees with a grant date fair value of $399.

During the six months ended June 30, 2013 and 2012, the Company repurchased/redeemed and retired the following shares of its preferred stock:

	Six months ended June 30,
	2013		2012

Noncontrolling Interests. In conjunction with several of the Company's acquisitions in prior years, sellers were issued OP units as a form of consideration. All OP units, other than OP units owned by the Company, are redeemable for common shares at certain times, at the option of the holders, and are generally not otherwise mandatorily redeemable by the Company. The OP units are classified as a component of permanent equity as the Company has determined that the OP units are not redeemable securities as defined by GAAP. Each OP unit is currently redeemable for approximately 1.13 common shares, subject to future adjustments.

During the six months ended June 30, 2013 and 2012, 164,596 and 66,652 common shares, respectively, were issued by the Company, in connection with OP unit redemptions, for an aggregate value of $861 and $353, respectively.

As of June 30, 2013, there were approximately 3,651,000 OP units outstanding other than OP units owned by the Company. All OP units receive distributions in accordance with their respective partnership agreements. To the extent that the Company's dividend per common share is less than the stated distribution per OP unit per the applicable partnership agreement, the distributions per OP unit are reduced by the percentage reduction in the Company's dividend per common share. No OP units have a liquidation preference.

The following discloses the effects of changes in the Company's ownership interests in its noncontrolling interests:

	Net Income Attributable to Shareholders and Transfers from Noncontrolling Interests
	Six Months ended June 30,
	2013		2012

Change from net income attributable to shareholders and transfers from noncontrolling interests	$	4,973	$	8,474

(12) Related Party Transactions

There were no other related party transactions other than those previously disclosed, including in this Quarterly Report on Form 10-Q for the six months ended June 30, 2013 and the audited consolidated financial statements in the Annual Report.

(13) Commitments and Contingencies

In addition to the commitments and contingencies disclosed elsewhere and previously disclosed, the Company has the following commitments and contingencies.

The Company is obligated under certain tenant leases to fund the expansion of the underlying leased properties. The Company, under certain circumstances, may guarantee to tenants the completion of base building improvements and the payment of tenant improvement allowances and lease commissions on behalf of its subsidiaries. As of June 30, 2013, the Company had two outstanding guarantees for (1) the completion of the base building improvements and the payment of a related tenant improvement allowance for an office property in Orlando, Florida, which the unfunded amounts were estimated to be $3,694 and (2) the payment of a tenant improvement allowance of $596 for a property in Allen, Texas.

From time to time, the Company is directly and indirectly involved in legal proceedings arising in the ordinary course of business. Management believes, based on currently available information, and after consultation with legal counsel, that although the outcomes of those normal course proceedings are uncertain, the results of such proceedings, in the aggregate, will not have a material adverse effect on the Company's business, financial condition and results of operations.

(14) Supplemental Disclosure of Statement of Cash Flow Information

In addition to disclosures discussed elsewhere, during the six months ended June 30, 2013 and 2012, the Company paid $48,377 and $49,305, respectively, for interest and $1,235 and $840, respectively, for income taxes.

(15) Subsequent Events

Subsequent to June 30, 2013 and in addition to disclosures elsewhere in the financial statements, the Company:

• converted $12,155 original principal amount of 6.00% Convertible Guaranteed Notes due 2030 for 1,777,562 common shares and a cash payment of $608;

• acquired its joint venture partner's interest in an industrial facility in Long Island City, New York for $8,662; and

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

Introduction

When we use the terms “the Company,” “we,” “us” and “our,” we mean Lexington Realty Trust and all entities owned by us, including non-consolidated entities, except where it is clear that the term means only the parent company. References herein to ‘‘this Quarterly Report” are to this Quarterly Report on Form 10-Q for the three and six months ended June 30, 2013. The result of operations for the three and six months ended June 30, 2013 and 2012 are not necessarily indicative of the results that may be expected for the full year.

The following is a discussion and analysis of our unaudited condensed consolidated financial condition and results of operations for the three and six months ended June 30, 2013 and 2012, and significant factors that could affect our prospective financial condition and results of operations. This discussion should be read together with the accompanying unaudited condensed consolidated financial statements and notes thereto and with our consolidated financial statements and notes thereto included in our most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission, or SEC, on February 25, 2013, which we refer to as our Annual Report. Historical results may not be indicative of future performance.

Forward-Looking Statements. This Quarterly Report, together with other statements and information publicly disseminated by us, contains certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, which we refer to as the Exchange Act. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 and include this statement for purposes of complying with these safe harbor provisions. Forward-looking statements, which are based on certain assumptions and describe our future plans, strategies and expectations, are generally identifiable by use of the words “believes,” “expects,” “intends,” “anticipates,” “estimates,” “projects,” “may,” “plans,” “predicts,” “will,” “will likely result” or similar expressions. Readers should not rely on forward-looking statements since they involve known and unknown risks, uncertainties and other factors which are, in some cases, beyond our control and which could materially affect actual results, performances or achievements. In particular, among the factors that could cause actual results, performances or achievements to differ materially from current expectations, strategies or plans include, among others, those risks discussed below in this "Management's Discussion and Analysis of Financial Condition and Results of Operations," and under the headings “Risk Factors” in this Quarterly Report and “Risk Factors” and “Management's Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report and other periodic reports filed with the SEC. Except as required by law, we undertake no obligation to publicly release the results of any revisions to these forward-looking statements which may be made to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events. Accordingly, there is no assurance that our expectations will be realized.

Overview

General. We are a self-managed and self-administered real estate investment trust, or REIT, formed under the laws of the state of Maryland. We operate primarily in one segment, single-tenant real estate assets, and our primary business is the investment in and the acquisition, ownership, financing and management of a geographically diverse portfolio of single-tenant office, industrial and retail properties. We conduct all of our property operations through property owner subsidiaries and lending operations through lender subsidiaries. A majority of our properties are subject to net or similar leases, where the tenant bears all or substantially all of the costs, including cost increases, for real estate taxes, utilities, insurance and ordinary repairs. In addition, we acquire, originate and hold investments in loan assets related to single-tenant real estate.

As of June 30, 2013, we had equity ownership interests in approximately 215 consolidated real estate properties, located in 41 states and encompassing 40.8 million square feet, 97.9% of which was leased. The properties in which we have an equity interest are leased to tenants in various industries, including finance/insurance, technology, service, automotive and energy.

Our revenues and cash flows are generated predominantly from property rent receipts. As a result, growth in revenues and cash flows is directly correlated to our ability to (1) acquire income producing real estate investments and (2) re-lease properties that are vacant, or may become vacant, at favorable rental rates.

Business Strategy. We continue to implement strategies which we believe will provide shareholders with dividend growth and capital appreciation. We believe that having a strong balance sheet supports these objectives. Since 2008, we believe we have strengthened our balance sheet primarily by (1) repurchasing and retiring our debt and senior securities or by extending their maturity date, (2) obtaining an investment-grade debt rating, (3) financing our properties with non-recourse mortgage debt or corporate credit facilities and term loans at what we believe are favorable rates and using the proceeds to retire higher rate or shorter term debt, (4) issuing equity when market conditions are favorable and (5) selling non-core and underperforming assets.

22

We have used proceeds from non-core and underperforming asset sales and issuances of common shares primarily to repurchase or retire our debt and acquire core assets.

Our core assets consist of general purpose, single-tenant net-leased office and industrial assets, in well-located and growing markets or which are critical to the tenant's business, but may also include other asset types subject to long-term net leases, such as retail facilities, schools and medical facilities. We believe education and health care are growing sectors of the U.S. economy and we have seen demand for build-to-suit transactions involving charter schools, private schools and medical facilities. In addition, we have been evaluating several ground lease investments. A component of our business strategy includes exploring these other asset types when they are subject to long-term leases that will extend the weighted-average lease term of our portfolio. We intend to mitigate residual value risk associated with such assets by acquiring such assets primarily through joint ventures or disposing of such assets when there is sufficient remaining lease term to generate favorable sale prices.

When opportunities arise, we intend to make investments in single-tenant assets, which we believe will generate favorable returns. We seek to grow our portfolio primarily by (1) engaging in, or providing funds to developers who are engaged in, build-to-suit projects for single-tenant corporate users, (2) providing capital to corporations by buying properties and leasing them back to the sellers under net or similar leases, (3) acquiring properties already subject to net or similar leases and (4) making mortgage and mezzanine loans generally secured by single-tenant properties subject to net or similar leases. While we expect to meet our acquisition targets for the year ending December 31, 2013, some investment opportunities are taking longer than expected to go under contract.

Portfolio diversification is central to our investment strategy as we seek to create and maintain an asset base that provides steady, predictable and growing cash flows while being insulated against rising property operating expenses, regional recessions, industry-specific downturns and fluctuations in property values and market rent levels. Regardless of capital market and economic conditions, we intend to stay focused on (1) enhancing operating results, (2) improving portfolio quality, (3) mitigating risks relating to interest rates and the real estate cycle and (4) implementing strategies where our management's skills and real estate expertise can add value. We believe that our business strategy will continue to improve our liquidity and strengthen our overall balance sheet while creating meaningful shareholder value.

Leasing Activity. Re-leasing properties that are currently vacant or as leases expire at favorable effective rates is one of our primary asset management focuses. We stay in close contact with our tenants during the lease term in order to assess their current and future occupancy needs and we maintain relationships with local brokers to determine the depth of the rental market. In addition, we monitor the credit of tenants of properties to stay abreast of any material changes in quality. We monitor tenant credit quality by (1) subscribing to Standard & Poor’s Rating Services, or S&P, and Moody’s Investors Service, Inc., or Moody’s, so that we can monitor changes in the ratings of our rated tenants, (2) reviewing financial statements that are publicly available or that are required to be delivered to us under the applicable lease, (3) monitoring news reports regarding our tenants and their respective businesses and (4) monitoring the timeliness of rent collections.

During the second quarter of 2013, we entered into 24 new leases and lease extensions encompassing 2.1 million square feet. The average U.S. generally accepted accounting principles, or GAAP, base rent on these extended leases was $11.60 per square foot compared to the average GAAP base rent on these leases before extension of $11.82 per square foot. The weighted-average cost of tenant improvements and lease commissions was $19.28 per square foot for new leases and $7.14 per square foot for extended leases.

Critical Accounting Policies

Management's discussion and analysis of financial condition and results of operations is based upon our unaudited condensed consolidated financial statements, which have been prepared in accordance with GAAP. In preparing our unaudited condensed consolidated financial statements in accordance with GAAP and pursuant to the rules and regulations of the SEC, we make assumptions, judgments and estimates that affect the reported amounts of assets, liabilities, revenue, and expenses, and related disclosures of contingent assets and liabilities. We base our assumptions, judgments and estimates on historical experience and various other factors that we believe to be reasonable under the circumstances. Actual results could differ materially from these estimates under different assumptions or conditions. On a regular basis, we evaluate our assumptions, judgments and estimates. Our accounting policies are discussed under (1) Item 7, “Management's Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report, (2) note 2 to our consolidated financial statements contained in our Annual Report and (3) note 1 to our unaudited condensed consolidated financial statements contained in this Quarterly Report. We believe there have been no material changes to the items that we disclosed as our critical accounting policies under Item 7, “Management's Discussion and Analysis of Financial Condition and Results of Operations,” in our Annual Report.

Liquidity and Capital Resources

Cash Flows. We believe that cash flows from operations will continue to provide adequate capital to fund our operating and administrative expenses, regular debt service obligations and all dividend payments in accordance with REIT requirements in both the short-term and long-term. In addition, we anticipate that cash on hand, borrowings under our unsecured credit facility, capital recycling proceeds, issuances of equity, mortgage proceeds and other debt, as well as other alternatives, will provide the necessary capital required by our business.

We generally seek to finance our balance sheet with property specific non-recourse mortgage debt, when appropriate, corporate level debt and equity. At June 30, 2013, we had $59.1 million and $83.0 million of property specific non-recourse mortgage debt due in 2013 and 2014, respectively. We believe we have sufficient sources of liquidity at June 30, 2013 to meet these obligations through cash on hand ($74.3 million), borrowing capacity on our unsecured revolving credit facility ($392.4 million), which expires in 2017, but can be extended by us to 2018, borrowing capacity on our five-year unsecured term loan ($186.0 million) and future cash flows from operations.

The mortgages encumbering the properties in which we have an interest are generally non-recourse to us, such that in situations where we believe it is beneficial to satisfy a mortgage obligation by transferring title of the property to the lender, including through a foreclosure, we may do so. During 2013, our properties in Southington, Connecticut, Suwanee, Georgia and Farmington Hills, Michigan were sold in foreclosure and our property in Indianapolis, Indiana was sold by a deed-in-lieu of foreclosure in satisfaction of the $49.5 million aggregate outstanding non-recourse mortgage loans. In January 2012, our vacant office property in Tulsa, Oklahoma was sold in foreclosure in satisfaction of the $7.1 million outstanding non-recourse mortgage loan.

Cash flows from operations as reported in the unaudited condensed consolidated statements of cash flows increased to $95.2 million for the six months ended June 30, 2013 from $80.9 million for the six months ended June 30, 2012. The increase is primarily related to operating results resulting from acquisitions, offset in part by the sales of properties. The underlying drivers that impact working capital, and therefore cash flows from operations, are the timing of collection of rents, including reimbursements from tenants, the collection of advisory fees, payment of interest on mortgage debt and payment of operating and general and administrative costs. We believe the net-lease structure of the leases encumbering a majority of the properties in which we have an interest mitigates the risks of the timing of cash flows from operations since the payment and timing of operating costs related to the properties are generally borne directly by the tenant. Collection and timing of tenant rents is closely monitored by management as part of our cash management program. The cash flows from operations for the six months ended June 30, 2013, were impacted by yield maintenance penalties and other costs incurred aggregating $12.4 million relating to the satisfaction of non-recourse, secured mortgage notes.

Net cash used in investing activities totaled $111.5 million and $16.9 million during the six months ended June 30, 2013 and 2012, respectively. Cash used in investing activities related primarily to acquisitions of real estate, investments in real estate under construction and loans receivable, capital expenditures and increases in leasing costs, restricted cash and real estate deposits. Cash provided by investing activities related primarily to proceeds from the sale of properties and a non-consolidated entity, distributions from non-consolidated entities in excess of accumulated earnings, release of escrow deposits and restricted cash and principal receipts on loans receivable.

25

Net cash provided by (used in) financing activities totaled $56.6 million and $(77.5) million during the six months ended June 30, 2013 and 2012, respectively. Cash provided by financing activities related primarily to proceeds from our unsecured senior notes, unsecured term loan and revolving credit facility advances, proceeds of mortgages and notes payable, contributions from noncontrolling interests and the net proceeds from the issuance of common shares, net. Cash used in financing activities was primarily attributable to dividend and distribution payments, retirement of debt instruments and preferred shares, principal payments on debt and increases in restricted cash and deferred financing costs.

Dividends. Dividends paid to our common and preferred shareholders increased to $68.2 million in the six months ended June 30, 2013, compared to $51.5 million in the six months ended June 30, 2012. This increase resulted from an increase in our quarterly common share dividend paid in 2013 to $0.15 per common share compared to $0.125 per common share per quarter paid in 2012 and an increase in the number of our outstanding common shares.

UPREIT Structure. As of June 30, 2013, there were 3.7 million units of limited partner interest, or OP units, in our operating partnerships outstanding other than OP units held by us. Assuming all outstanding OP units not held by us were redeemed on such date, the estimated fair value of the OP units was $48.0 million based on the closing price of $11.68 per common share on June 28, 2013 and a redemption factor of approximately 1.13.

Financings. In June 2013, we issued $250.0 million aggregate principal amount of 4.25% Senior Notes due 2023 at an issuance price of 99.026% of the principal amount. The notes are unsecured, pay interest semi-annually in arrears and mature in June 2023. We may redeem the notes at our option at any time prior to maturity in whole or in part by paying the principal amount of the notes being redeemed plus a premium. We recognized an aggregate initial discount of $2.4 million upon issuance of the notes which will be recognized as additional interest expense over the term of the notes. The notes are rated Baa2 and BBB- by Moody’s and S&P, respectively.

On February 12, 2013, we refinanced our $300.0 million secured revolving credit facility with a $300.0 million unsecured revolving credit facility with KeyBank National Association, or KeyBank, as agent. The unsecured revolving credit facility matures in February 2017 but can be extended until February 2018 at our option. The unsecured revolving credit facility bore interest at LIBOR plus 1.50% to 2.05% based on our leverage ratio, as defined therein. Since we have obtained an investment-grade unsecured debt rating from both Moody’s and S&P, the interest rate under the unsecured revolving credit facility ranges from LIBOR plus 0.95% to 1.725% (1.15% as of June 30, 2013) depending on our unsecured debt rating. During the six months ended June 30, 2013, we increased availability under the unsecured revolving credit facility from $300.0 million to $400.0 million. At June 30, 2013, the unsecured revolving credit facility had no amounts outstanding, outstanding letters of credit of $7.6 million and availability of $392.4 million, subject to covenant compliance.

In connection with the refinancing discussed above, we also procured a five-year $250.0 million unsecured term loan facility from KeyBank, as agent. The unsecured term loan matures in February 2018, required regular payments of interest only at interest rates ranging from LIBOR plus 1.45% to 2.00% dependent on our leverage ratio, as defined therein and may be prepaid without penalty. Since we have obtained an investment-grade unsecured debt rating from both Moody’s and S&P, the interest rate under the unsecured term loan ranges from LIBOR plus 1.10% to 2.10% (1.35% as of June 30, 2013) depending on our unsecured debt rating. As of June 30, 2013, we have entered into an interest-rate swap agreement to fix LIBOR at 0.73% through February 2018 on the $64.0 million outstanding. At June 30, 2013, the unsecured term loan had availability of $186.0 million, subject to covenant compliance.

During 2012, we procured a $255.0 million secured term loan from Wells Fargo Bank, National Association, as agent.  The term loan was secured by ownership interest pledges by certain subsidiaries that collectively owned a borrowing base of properties.  The term loan matures in January 2019 and required regular payments of interest only at interest rates that ranged from LIBOR plus 2.00% to 2.85% dependent on our leverage ratio, as defined therein. Since we have obtained an investment-grade unsecured debt rating from both Moody’s and S&P, the interest rate under the term loan ranges from 1.50% to 2.25% (1.75% as of June 30, 2013) depending on our unsecured debt rating. We may prepay outstanding borrowings under the term loan at a premium through January 12, 2016 and at par thereafter. We entered into interest-rate swap agreements to fix LIBOR at a weighted-average rate of 1.42% on the $255.0 million of term loan LIBOR-based debt through January 2019. In February 2013, we amended the term loan to release the collateral as security.

As of June 30, 2013, we were in compliance with the financial covenants contained in the revolving credit facility and term loan agreements.

During the first quarter of 2013, we financed our Lenexa, Kansas property with non-recourse mortgage financing in the aggregate original principal amount of $40.0 million which bears interest at an initial fixed weighted-average rate of 3.70% and matures in 2027.

Common Offering / At-The-Market Offering Program

In March 2013, we issued 23.0 million common shares in a public offering and raised gross proceeds of $258.3 million. In 2013, we implemented an At-The-Market offering program under which we may issue up to $100 million in common shares over the term of the program. We issued 3.4 million common shares under the program generating aggregate gross proceeds of $36.9 million during the six months ended June 30, 2013. We used a portion of the aggregate net proceeds from these offerings of $293.9 million to satisfy the $137.9 million outstanding balance on our unsecured revolving credit facility and the remainder for general corporate purposes, including, without limitation, investments.

Results of Operations

Three months ended June 30, 2013 compared with three months ended June 30, 2012. The increase in total gross revenues in 2013 of $18.6 million was primarily attributable to an increase in rental revenue of $18.3 million and an increase in tenant reimbursements of $0.9 million, offset by a $0.6 million decrease in advisory and incentive fees. Rental revenue increased primarily due to (1) new property acquisition revenue of $17.7 million, including $10.5 million from Net Lease Strategic Assets Fund L.P., or NLS, properties acquired on September 1, 2012 and (2) $0.8 million of increased revenue recognized from our office property in Palo Alto, California due to a lease extension, offset by the net impact of lease extensions entered into at rents below previous rental amounts and new leases entered into. The increase in tenant reimbursements relates to the acquisition of the NLS properties and an increase in reimbursable property operating costs. The decrease in advisory and incentive fees relates to the acquisition of the NLS properties, therefore advisory fees are no longer earned by us.

Depreciation and amortization increased by $7.8 million primarily due to the acquisition of real estate properties.

The increase in property operating expenses of $2.0 million was primarily due to an increase in occupancy and use in certain multi-tenanted properties, the acquisition of NLS and an increase in vacancy at certain properties.

The decrease in interest and amortization expense of $0.8 million was primarily due to a reduction in the average interest rate on our indebtedness, offset by a reduction of $0.3 million in interest capitalized.

The increase in debt satisfaction charges, net of $11.7 million was primarily due to debt defeasance charges and write-offs of deferred loan costs recognized in the three months ended June 30, 2013 relating to the satisfaction of $193.2 million of non-recourse mortgage debt.

The decrease in litigation reserve of $2.8 million relates to our litigation with Deutsche Bank Securities, Inc. and SPCP Group LLC, which was settled in 2012.

The decrease in equity in earnings of non-consolidated entities of $10.1 million was primarily due to (1) a $2.9 million decrease in earnings from NLS due to the consolidation of NLS on September 1, 2012 and (2) $7.2 million recognized on our investments in Concord Debt Holdings LLC, or Concord, and CDH CDO LLC, in 2012, which were sold during the second quarter of 2012.

Discontinued operations represent properties sold or held for sale. The increase in total income from discontinued operations of $11.9 million was primarily due to an increase in gains on sales of properties of $10.1 million, a decrease in loss from discontinued operations of $2.5 million and a decrease in impairment charges of $1.7 million, offset by an increase in debt satisfaction charges, net, of $1.3 million and an increase of $1.2 million in the provision for income taxes primarily due to the sales of properties held by our taxable REIT subsidiary.

The decrease in net loss attributable to common shareholders of $2.5 million was primarily due to the items discussed above and the change in actual preferred dividends and deemed preferred dividends relating to the redemption of preferred shares.

Six months ended June 30, 2013 compared with six months ended June 30, 2012. The increase in total gross revenues in 2013 of $36.7 million is primarily attributable to an increase in rental revenue and tenant reimbursements of $35.9 million and $1.6 million, respectively, offset in part by a decrease in advisory and incentive fees of $0.8 million. The increase in rental revenue was primarily due to (1) new property acquisition revenue of $32.4 million, including $21.0 million from NLS properties and (2) $1.5 million of increased revenue recognized from our office property in Palo Alto, California due to a lease extension, coupled with the net impact of lease extensions entered into at rents below previous rental amounts and new leases entered into. The increase in tenant reimbursements relates to the acquisition of the NLS properties and an increase in reimbursable property operating costs. The decrease in advisory and incentive fees relates to the acquisition of the NLS properties, therefore advisory fees are no longer earned by us.

27

Depreciation and amortization increased $15.5 million primarily due to the acquisition of real estate properties.

The increase in property operating expenses of $4.2 million was primarily due to an increase in occupancy and the NLS acquisition.

The decrease in interest and amortization expense of $1.0 million was primarily due to (1) a reduction in the average interest rate on our indebtedness, (2) retirement of debt which had corresponding debt discount amortization and (3) greater interest capitalized.

The increase in general and administrative expense of $2.2 million was primarily due to an increase in personnel costs, trustee fees and professional fees.

Non-operating income decreased $0.8 million primarily due to the satisfaction of notes receivable resulting in less interest earned and reduced interest income earned on a note receivable currently in default secured by an office property in Schaumburg, Illinois for which we ceased recognizing interest income commencing in the three months ending June 30, 2012.

The decrease in litigation reserve of $2.8 million relates to our litigation with Deutsche Bank Securities, Inc. and SPCP Group LLC, which was settled in 2012.

The increase in debt satisfaction charges, net of $21.1 million was primarily due to (1) an increase of $10.4 million of debt defeasance costs and write-off of deferred financing costs relating to the satisfaction of $338.5 million in secured nonrecourse mortgage debt in 2013 and (2) $10.6 million of debt satisfaction charges recognized upon the conversion in 2013 of $42.8 million 6.00% Convertible Guaranteed Notes due in 2030.

Impairment charges of $2.4 million in 2013 relates to an impairment charge on a retail property owned in Port Chester, New York which we had considered selling and its carrying value was in excess of its estimated fair value.

The decrease in equity in earnings of non-consolidated entities of $17.3 million was primarily due to income of $7.9 million recognized from our interests in Concord and CDH CDO LLC in 2012 and a $9.3 million decrease in earnings from NLS due to the consolidation of NLS on September 1, 2012.

Discontinued operations represent properties sold or held for sale. The increase in total income from discontinued operations of $17.7 million is primarily due to an increase in debt satisfaction gains, net of $7.5 million, a $4.3 million increase in income from discontinued operations and an increase in gains on sales of properties of $10.1 million, offset in part by an increase in impairment charges of $3.0 million and a $1.2 million increase in the provision for income taxes due to the sales of properties held in our taxable REIT subsidiary.

The decrease in net income attributable to noncontrolling interests of $1.4 million was primarily due to a decrease in gain on sales of properties incurred by a non-wholly owned entity.

The increase in net loss attributable to common shareholders of $2.6 million was primarily due to the items discussed above, offset by a net decrease of $1.5 million in actual and deemed dividends and a redemption discount attributable to our preferred stock.

The increase in net income in future periods will be closely tied to the level of acquisitions made by us and leasing activity. Without acquisitions and favorable leasing activity, the sources of growth in net income are limited to index-adjusted rents (such as the consumer price index), reduced interest expense on amortizing mortgages and debt refinancings and by controlling other variable overhead costs. However, there are many factors beyond management's control that could offset these items including, without limitation, increased interest rates, decreased occupancy rates, and tenant monetary defaults and the other risks described in our periodic reports filed with the SEC.

Same-Store Results

Same-store results include all consolidated properties except properties acquired and/or sold in 2013 and 2012. Our historical same-store occupancy was 97.7% at June 30, 2013 compared to 97.9% at June 30, 2012. The following presents our consolidated same-store net operating income, or NOI, for the six months ended June 30, 2013 and 2012 ($000):

	2013			2012
Total base rent	$	141,617		$	142,595
Tenant reimbursements	14,757			14,225
Property operating expenses	(29,603		)	(26,856		)
Same-store NOI	$	126,771		$	129,964

28

The change in our same-store NOI from 2012 to 2013 was a decrease of 2.5%. This was primarily due to an increase in property operating expenses due to the timing of new tenant leases and the establishment of base years for certain tenants.

Funds From Operations

We believe that Funds from Operations, or FFO, which is a non-GAAP measure, is a widely recognized and appropriate measure of the performance of an equity REIT. We believe FFO is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs, many of which present FFO when reporting their results. FFO is intended to exclude GAAP historical cost depreciation and amortization of real estate and related assets, which assumes that the value of real estate diminishes ratably over time. Historically, however, real estate values have risen or fallen with market conditions. As a result, FFO provides a performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, development activities, interest costs and other matters without the inclusion of depreciation and amortization, providing perspective that may not necessarily be apparent from net income.

The National Association of Real Estate Investment Trusts, or NAREIT, defines FFO as “net income (or loss) computed in accordance with GAAP, excluding gains (or losses) from sales of property, plus real estate depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures.” NAREIT clarified its computation of FFO to exclude impairment charges on depreciable real estate owned directly or indirectly. FFO does not represent cash generated from operating activities in accordance with GAAP and is not indicative of cash available to fund cash needs.

We present Reported Company FFO, which differs from FFO because it includes our operating partnership units, our 6.50% Series C Cumulative Convertible Preferred Stock, and our 6.00% Convertible Guaranteed Notes due 2030 because these securities are convertible, at the holder's option, into our common shares. Management believes this is appropriate and relevant to securities analysts, investors and other interested parties because we present Reported Company FFO on a company-wide basis as if all securities that are convertible, at the holder's option, into our common shares, were converted. We also present Company FFO, as adjusted, which adjusts Reported Company FFO for certain items which we believe are nonrecurring and not indicative of the operating results of our real estate portfolio. We believe this is an appropriate presentation as it is frequently requested by security analysts, investors and other interested parties. Since others do not calculate funds from operations in a similar fashion, Reported Company FFO and Company FFO, as adjusted, may not be comparable to similarly titled measures as reported by others. Reported Company FFO and Company FFO, as adjusted, should not be considered as an alternative to net income as an indicator of our operating performance or as an alternative to cash flow as a measure of liquidity.

Off-Balance Sheet Arrangements

As of June 30, 2013, we had investments in various real estate entities with varying structures. The real estate investments owned by these entities are generally financed with non-recourse debt. Non-recourse debt is generally defined as debt whereby the lenders' sole recourse with respect to borrower defaults is limited to the value of the assets collateralized by the debt. The lender generally does not have recourse against any other assets owned by the borrower or any of the members or partners of the borrower, except for certain specified exceptions listed in the particular loan documents. These exceptions generally relate to "bad boy" acts, including fraud and breaches of material representations. We have guaranteed such obligations for certain of our property owner subsidiaries. We have also agreed to indemnify a third-party for any draws on a letter of credit securing similar non-recourse exceptions with respect to an investment we formerly owned but now manage. Upon expiration of such letter of credit, we have agreed to deliver a replacement $2.5 million letter of credit.

In addition, we had $7.6 million in outstanding letters of credit at June 30, 2013.

ITEM 3. QUANTITATIVE AND QUALITATIVE

DISCLOSURES ABOUT MARKET RISK

Our exposure to market risk relates primarily to our variable-rate debt not subject to interest rate swaps and our fixed-rate debt. Our consolidated variable-rate indebtedness was $0 and $35.0 million as of June 30, 2013 and 2012, respectively, which represented 0% and 2.0% of total long-term indebtedness, respectively. During the three months ended June 30, 2013 and 2012, our variable-rate indebtedness had a weighted-average interest rate of 2.0% and 2.7%, respectively. Had the weighted-average interest rate been 100 basis points higher, our interest expense for the three months ended June 30, 2013 and 2012 would have been increased by $343 thousand and $146 thousand, respectively. During the six months ended June 30, 2013 and 2012, our variable interest rate indebtedness had a weighted-average interest rate of 2.0% and 2.7%, respectively. Had the weighted-average interest rate been 100 basis points higher, our interest expense for the six months ended June 30, 2013 and 2012 would have been increased by $447 thousand and $287 thousand, respectively. As of June 30, 2013 and 2012, our consolidated fixed-rate debt was $1.8 billion and $1.7 billion, respectively, which represented 100.0% and 98.0%, respectively, of total long-term indebtedness.

For certain of our financial instruments, fair values are not readily available since there are no active trading markets as characterized by current exchanges between willing parties. Accordingly, we derive or estimate fair values using various valuation techniques, such as computing the present value of estimated future cash flows using discount rates commensurate with the risks involved. However, the determination of estimated cash flows may be subjective and imprecise. Changes in assumptions or estimation methodologies can have a material effect on these estimated fair values. The following fair value was determined using the interest rates that we believe our outstanding fixed-rate debt would warrant as of June 30, 2013 and are indicative of the interest rate environment as of June 30, 2013, and do not take into consideration the effects of subsequent interest rate fluctuations. Accordingly, we estimate that the fair value of our fixed-rate debt was $1.8 billion as of June 30, 2013.

Our interest rate risk objectives are to limit the impact of interest rate fluctuations on earnings and cash flows and to lower our overall borrowing costs. To achieve these objectives, we manage our exposure to fluctuations in market interest rates through the use of fixed-rate debt instruments to the extent that reasonably favorable rates are obtainable with such arrangements. We may enter into derivative financial instruments such as interest rate swaps or caps to mitigate our interest rate risk on a related financial instrument or to effectively lock the interest rate on a portion of our variable-rate debt. As of June 30, 2013, we had six interest rate swap agreements (see note 9 to our unaudited condensed consolidated financial statements contained in this Quarterly Report).

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of such period, our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and that information required to be disclosed by us in reports filed or submitted under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Internal Control Over Financial Reporting. There have been no significant changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fiscal quarter to which this report relates that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the Effectiveness of Controls.Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting objectives because of its inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements may not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk.

Concentration of Risk

6 Months Ended

Jun. 30, 2013

Concentration of Risk [Abstract]

Concentration of Risk

Concentration of Risk

The Company seeks to reduce its operating and leasing risks through the geographic diversification of its properties, tenant industry diversification, avoidance of dependency on a single asset and the creditworthiness of its tenants. For the six months ended June 30, 2013 and 2012, no single tenant represented greater than 10% of rental revenues.

Cash and cash equivalent balances at certain institutions may exceed insurable amounts. The Company believes it mitigates this risk by investing in or through major financial institutions.

(1) The Company’s consolidated partnership, which owns the Long Island City, New York property, provided as of June 30, 2013 for the Company to receive distributions of operating cash flows as follows: (1) a 6.3% priority return on its invested capital up to $25,000, (2) an 11% priority return on its invested capital in excess of $25,000 and (3) approximately 50% of any excess return. Subsequent to June 30, 2013, the Company acquired its joint venture partners’ interest in the partnership.

(2) The Company incurred additional initial costs of $3,825 which are included in “Other assets” in the accompanying unaudited condensed consolidated balance sheet.

(3) The Company incurred leasing costs of $323.

The Company recognized aggregate acquisition expenses of $250 and $380 for the six months ended June 30, 2013 and 2012, respectively, which are included as operating expenses within the Company's unaudited condensed consolidated statements of operations.

The Company is engaged in various forms of build-to-suit development activities. The Company, through lender subsidiaries and property owner subsidiaries, may enter into the following acquisition, development and construction arrangements: (1) lend funds to construct build-to-suit projects subject to a single-tenant lease and agree to purchase the properties upon completion of construction and commencement of a single-tenant lease, (2) hire developers to construct built-to-suit projects on owned properties leased to single tenants, (3) fund the construction of build-to-suit projects on owned properties pursuant to the terms in single-tenant lease agreements or (4) enter into purchase and sale agreements with developers to acquire single-tenant build-to-suit properties upon completion.

As of June 30, 2013, the Company had the following development arrangements outstanding:

Location	Property Type	Square Feet	Expected Maximum Commitment/Contribution ($ millions)		Lease Term (Years)	Estimated Completion Date
Rantoul, IL	Industrial	813,000	$	42.6	20	4Q 13
Bingen, WA	Industrial	124,000	$	18.9	12	2Q 14
Las Vegas, NV(1)	Industrial	180,000	$	29.6	20	3Q 14
Albany, GA	Retail	46,000	$	7.5	15	4Q 13
		1,163,000	$	98.6

(1) At June 30, 2013, the Company's commitment could have been terminated by the Company due to an outstanding contingency, thus costs incurred through June 30, 2013 of $1,191 are recognized as pre-development costs and included in “Other assets” in the accompanying unaudited condensed consolidated balance sheet. Subsequent to June 30, 2013, the termination right expired.

The Company has variable interests in certain developer entities constructing the facilities but is not the primary beneficiary of the entities as the Company does not have a controlling financial interest. As of June 30, 2013 and December 31, 2012, the Company's aggregate investment in development arrangements, excluding the Las Vegas, Nevada property, was $23,099 and $65,122, respectively, and are presented as investments in real estate under construction in the accompanying unaudited condensed consolidated balance sheets. The Company capitalized interest of $1,116 and $1,046 during the six months ended June 30, 2013 and 2012, respectively, relating to build-to-suit activities.

In addition, the Company has committed to acquire, upon its completion, an office property in Omaha, Nebraska for $39,125, which is subject to a net lease that will have a 20-year term upon completion. Construction is expected to be completed in the fourth quarter of 2013. The Company can give no assurances that any of these acquisitions under contract or build-to-suit transactions will be consummated.

On September 1, 2012, the Company, together with an operating partnership subsidiary, acquired the remaining common equity interest in Net Lease Strategic Assets Fund L.P. ("NLS") from Inland American (Net Lease) Sub, LLC that the Company did not already own for a cash payment of $9,438 and the assumption of all outstanding liabilities. Immediately prior to the acquisition, the Company owned 15% of NLS's common equity and 100% of NLS's preferred equity. At the date of acquisition, NLS owned 41 properties totaling 5.8 million square feet in 23 states, plus a 40% tenant-in-common interest in an office property.  The Company's investment in NLS had previously been accounted for under the equity method and is now consolidated.

The Company recognized gross revenues from continuing operations of $21,505 and a net loss of $(3,542) from NLS properties during the six months ended June 30, 2013. The Company recognized $9,306 of equity in earnings relating to NLS during the six months ended June 30, 2012.

The following unaudited condensed consolidated pro forma information is presented as if the Company acquired the remaining equity in NLS on January 1, 2012. The information presented below is not necessarily indicative of what the actual results of operations would have been had the transaction been completed on January 1, 2012, nor does it purport to represent the Company's future operations:

During the six months ended June 30, 2013, the Company implemented an At-The-Market offering program under which the Company may issue up to $100,000 in common shares over the term of this program. The Company issued 3,409,927 common shares under this program during the six months ended June 30, 2013 and generated aggregate gross proceeds of $36,884. In addition, in March 2013, the Company issued 23,000,000 common shares in a public offering raising gross proceeds of $258,336. The net proceeds from these offerings of $293,934 were used to repay borrowings under the Company's unsecured revolving credit facility and the balance for general corporate purposes, including acquisitions.

The Company issued 1,325,000 non-vested common shares to certain officers with a grant date fair value of $14,098 during the six months ended June 30, 2013. The non-vested common shares are subject to long-term retention non-vested share agreements and vest from 2018 to 2022 in accordance with the agreements. In addition, the Company issued 37,500 fully vested common shares to the non-management members of the Company's Board of Trustees with a grant date fair value of $399.

During the six months ended June 30, 2013 and 2012, the Company repurchased/redeemed and retired the following shares of its preferred stock:

(1) Includes accrued and unpaid dividends.

(2) Represents the difference between the redemption/repurchase cost and historical GAAP cost.

Accordingly, net income was adjusted for the deemed dividends/deemed negative dividends to arrive at net loss attributable to common shareholders.

Accumulated other comprehensive income (loss) as of June 30, 2013 and December 31, 2012 represented $3,912 and $(6,224), respectively, of unrealized gain (loss) on interest rate swaps, net.

Noncontrolling Interests. In conjunction with several of the Company's acquisitions in prior years, sellers were issued OP units as a form of consideration. All OP units, other than OP units owned by the Company, are redeemable for common shares at certain times, at the option of the holders, and are generally not otherwise mandatorily redeemable by the Company. The OP units are classified as a component of permanent equity as the Company has determined that the OP units are not redeemable securities as defined by GAAP. Each OP unit is currently redeemable for approximately 1.13 common shares, subject to future adjustments.

During the six months ended June 30, 2013 and 2012, 164,596 and 66,652 common shares, respectively, were issued by the Company, in connection with OP unit redemptions, for an aggregate value of $861 and $353, respectively.

As of June 30, 2013, there were approximately 3,651,000 OP units outstanding other than OP units owned by the Company. All OP units receive distributions in accordance with their respective partnership agreements. To the extent that the Company's dividend per common share is less than the stated distribution per OP unit per the applicable partnership agreement, the distributions per OP unit are reduced by the percentage reduction in the Company's dividend per common share. No OP units have a liquidation preference.

The following discloses the effects of changes in the Company's ownership interests in its noncontrolling interests:

	Net Income Attributable to Shareholders and Transfers from Noncontrolling Interests
	Six Months ended June 30,
	2013		2012
Net income attributable to Lexington Realty Trust shareholders	$	4,112	$	8,121

The Company and Financial Statement Presentation [Abstract]

The Company and Financial Statement Presentation

The Company and Financial Statement Presentation

Lexington Realty Trust (the “Company”) is a self-managed and self-administered Maryland statutory real estate investment trust (“REIT”) that invests in and acquires, owns, finances and manages a geographically diversified portfolio of predominately single-tenant office, industrial and retail properties. The Company also provides investment advisory and asset management services to investors in the single-tenant area. As of June 30, 2013, the Company had equity ownership interests in approximately 215 consolidated properties in 41 states. A majority of the real properties in which the Company has an equity ownership interest are generally subject to net or similar leases where the tenant bears all or substantially all of the cost, including cost increases, for real estate taxes, insurance, utilities and ordinary maintenance of the property. However, certain leases provide that the landlord is responsible for certain or all operating expenses. In addition, we acquire, originate and hold investments in loan assets related to single-tenant real estate.

The Company believes it has qualified as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). Accordingly, the Company will not be subject to federal income tax, provided that distributions to its shareholders equal at least the amount of its REIT taxable income as defined under the Code. The Company is permitted to participate in certain activities in order to maintain its qualification as a REIT, so long as these activities are conducted in entities which elect to be treated as taxable REIT subsidiaries (“TRS”) under the Code. As such, the TRS are subject to federal income taxes on the income from these activities.

The Company conducts its operations either directly or indirectly through (1) property owner subsidiaries and lender subsidiaries, (2) operating partnerships in which the Company is the sole unit holder of the general partner and the sole unit holder of the limited partner that holds a majority of the limited partner interests (“OP units”), (3) a wholly-owned TRS, or (4) investments in joint ventures. Property owner subsidiaries are landlords under leases for properties in which the Company has an interest and/or borrowers under loan agreements secured by properties in which the Company has an investment and lender subsidiaries are lenders under loan agreements where the Company made an investment in a loan asset, but in all cases are separate and distinct legal entities.

Basis of Presentation and Consolidation. The Company's unaudited condensed consolidated financial statements are prepared on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles (“GAAP”). The financial statements reflect the accounts of the Company and its consolidated subsidiaries. The Company consolidates its wholly-owned subsidiaries and its partnerships and joint ventures which it controls (1) through voting rights or similar rights or (2) by means other than voting rights if the Company is the primary beneficiary of a variable interest entity ("VIE"). Entities which the Company does not control and entities which are VIEs in which the Company is not the primary beneficiary are accounted for under appropriate GAAP.

The financial statements contained herein have been prepared by the Company in accordance with GAAP for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all information and footnotes required by GAAP for complete financial statements. However, in the opinion of management, the interim financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results of the periods presented. The results of operations for the three and six months ended June 30, 2013 and 2012, are not necessarily indicative of the results that may be expected for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes thereto included in the Company's Form 10-K for the year ended December 31, 2012 filed with the SEC on February 25, 2013 (“Annual Report”).

Use of Estimates. Management has made a number of significant estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses to prepare these unaudited condensed consolidated financial statements in conformity with GAAP. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. The current economic environment has increased the degree of uncertainty inherent in these estimates and assumptions. Management adjusts such estimates when facts and circumstances dictate. The most significant estimates made include the recoverability of accounts receivable, the allocation of property purchase price to tangible and intangible assets acquired and liabilities assumed, the determination of VIEs and which entities should be consolidated, the determination of impairment of long-lived assets, loans receivable and equity method investments, the valuation of derivative financial instruments and the useful lives of long-lived assets. Actual results could differ materially from those estimates.

Fair Value Measurements. The Company follows the guidance in the Financial Accounting Standards Board Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures, as amended (“Topic 820”), to determine the fair value of financial and non-financial instruments. Topic 820 defines fair value, establishes a framework for measuring fair value in GAAP and expands disclosures about fair value measurements. Topic 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 - quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities; Level 2 - observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 - unobservable inputs, which are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as considering counterparty credit risk. The Company has formally elected to apply the portfolio exception within Topic 820 with respect to measuring counterparty risk for all of its derivative transactions subject to master netting arrangements.

Acquisition, Development and Construction Arrangements. The Company evaluates loans receivable where the Company participates in residual profits through loan provisions or other contracts to ascertain whether the Company has the same risks and rewards as an owner or a joint venture partner. Where the Company concludes that such arrangements are more appropriately treated as an investment in real estate, the Company reflects such loan receivable as an equity investment in real estate under construction in the unaudited condensed consolidated balance sheets. In these cases, no interest income is recorded on the loan receivable and the Company records capitalized interest during the construction period. In arrangements where the Company engages a developer to construct a property or provides funds to a tenant to develop a property, the Company will capitalize the funds provided to the developer/tenant and internal costs of interest and real estate taxes, if applicable, during the construction period.

Reclassifications. Certain amounts included in the 2012 unaudited condensed consolidated financial statements have been reclassified, primarily relating to discontinued operations, to conform to the 2013 presentation.

Recently Issued Accounting Guidance. In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-02: Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, to improve the transparency of reporting the reclassifications of significant amounts out of accumulated other comprehensive income. This guidance requires entities to present the effects on the line items of net income of significant reclasses from accumulated other comprehensive income, either where net income is presented or in the notes, as well as cross-reference to other disclosures currently required under GAAP for other reclassification items (that are not required under GAAP) to be reclassified directly to net income in their entirety in the same reporting period. The new disclosure requirements are effective for annual reporting periods beginning after December 15, 2012. The new disclosures are required for both interim and annual reporting. The implementation of this guidance did not have an impact on the Company's financial position, results of operations or cash flows.

Real Estate and Discontinued Operations

Discontinued Operations and Real Estate Impairment

During the six months ended June 30, 2013, the Company disposed of its interests in certain properties to unrelated third parties for an aggregate gross disposition price of $48,466. In addition, the Company conveyed certain properties along with the respective escrow deposits in satisfaction of an aggregate $49,509 of non-recourse secured mortgage loans and recognized aggregate net gains on debt satisfaction of $9,250. These dispositions resulted in an aggregate gain on sales of properties of $12,806. During the six months ended June 30, 2012, the Company disposed of its interests in certain properties to unrelated third parties for an aggregate gross disposition price of $74,815 and recognized an aggregate gain on sales of properties of $2,671. In addition, the Company conveyed a property in satisfaction of the $7,119 non-recourse secured mortgage loan and recognized a net gain on debt satisfaction of $1,728. As of June 30, 2013 and 2012, the Company had no properties classified as held for sale.

The following presents the operating results for the properties sold for the applicable periods:

	Three months ended June 30,					Six months ended June 30,
	2013		2012			2013		2012
Total gross revenues	$	876	$	4,833		$	2,408	$	10,151
Pre-tax income (loss)	$	10,069	$	(3,015	)	$	14,993	$	(3,872	)

The Company assesses on a regular basis whether there are any indicators that the carrying value of its real estate assets may be impaired. Potential indicators may include an increase in vacancy at a property, tenant reduction in utilization of a property, tenant financial instability and the potential sale of the property in the near future. An asset is determined to be impaired if the asset's carrying value is in excess of its estimated fair value. During the six months ended June 30, 2013 and 2012, the Company recognized $8,735 and $5,690, respectively, of impairment charges in discontinued operations, relating to real estate assets that were disposed below their carrying value.

In addition, the Company recognized an impairment charge of $2,413 in continuing operations during the six months ended June 30, 2013. The Company explored the possible disposition of a non-core retail property and determined that the expected undiscounted cash flows based upon a revised estimated holding period of the property was below the current carrying value. Accordingly, the Company reduced the carrying value of this property to its estimated fair value.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

A significant portion of the Company's non-vested share-based payment awards are considered participating securities and as such, the Company is required to use the two-class method for the computation of basic and diluted earnings per share. Under the two-class computation method, net losses are not allocated to participating securities unless the holder of the security has a contractual obligation to share in the losses. The non-vested share-based payment awards are not allocated losses as the awards do not have a contractual obligation to share in losses of the Company.

The following is a reconciliation of the numerators and denominators of the basic and diluted earnings per share computations for the three and six months ended June 30, 2013 and 2012:

Investment in and Advances to Non Consolidated Entities [Abstract]

Investment in and Advances to Non-Consolidated Entities

Investment in and Advances to Non-Consolidated Entities

During 2012, the Company formed two joint ventures in which it has a minority interest. One joint venture acquired a 120,000 square foot retail property in Palm Beach Gardens, Florida for $29,750 which was net leased for an approximate 15-year term. The Company had a 36% interest in the venture and provided a $12,000 non-recourse mortgage loan to the venture which was repaid in full in February 2013. The Company received a distribution of $2,557 in March 2013, a portion of which represented a return of capital reducing the Company's ownership interest to 25%.

The second joint venture, in which the Company has a 15% interest, acquired a 100% economic interest in an inpatient rehabilitation hospital in Humble, Texas for $27,750, which was net leased for an approximate 17-year term. The acquisition was partially funded by a non-recourse mortgage with an original principal amount of $15,260, which bears interest at a fixed rate of 4.7% and matures in May 2017.

Pemlex LLC. In July 2012, the Company sold its interest in Pemlex LLC for $13,218 in connection with a restructuring of Pemlex LLC. In addition, the Company (1) entered into a management agreement with the purchaser that provides for a backstop guaranty to a third party who delivered a letter of credit in the amount of $2,500 as security for "bad boy" acts under the purchaser's third-party acquisition financing and (2) agreed to deliver a replacement letter of credit, if necessary, in the amount of $2,500 to the purchaser's lender during the term of the management agreement. No gain or loss was recognized in the transaction as the investment was sold at its cost basis.

Concord Debt Holdings LLC (“Concord”) and CDH CDO LLC ("CDH CDO"). The Company's investments in Concord and CDH CDO were valued at zero and the Company recognized income on the cash basis. During the six months ended June 30, 2012, the Company received aggregate distributions of $885, which were recorded as equity in earnings of non-consolidated entities. During the second quarter of 2012, the Company sold all of its interest in Concord and CDH CDO for $7,000 in cash.

The Company and Financial Statement Presentation (Policies)

6 Months Ended

Jun. 30, 2013

The Company and Financial Statement Presentation [Abstract]

Basis of Presentation and Consolidation

Basis of Presentation and Consolidation. The Company's unaudited condensed consolidated financial statements are prepared on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles (“GAAP”). The financial statements reflect the accounts of the Company and its consolidated subsidiaries. The Company consolidates its wholly-owned subsidiaries and its partnerships and joint ventures which it controls (1) through voting rights or similar rights or (2) by means other than voting rights if the Company is the primary beneficiary of a variable interest entity ("VIE"). Entities which the Company does not control and entities which are VIEs in which the Company is not the primary beneficiary are accounted for under appropriate GAAP.

The financial statements contained herein have been prepared by the Company in accordance with GAAP for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all information and footnotes required by GAAP for complete financial statements. However, in the opinion of management, the interim financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results of the periods presented. The results of operations for the three and six months ended June 30, 2013 and 2012, are not necessarily indicative of the results that may be expected for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes thereto included in the Company's Form 10-K for the year ended December 31, 2012 filed with the SEC on February 25, 2013 (“Annual Report”).

Use of Estimates

Use of Estimates. Management has made a number of significant estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses to prepare these unaudited condensed consolidated financial statements in conformity with GAAP. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. The current economic environment has increased the degree of uncertainty inherent in these estimates and assumptions. Management adjusts such estimates when facts and circumstances dictate. The most significant estimates made include the recoverability of accounts receivable, the allocation of property purchase price to tangible and intangible assets acquired and liabilities assumed, the determination of VIEs and which entities should be consolidated, the determination of impairment of long-lived assets, loans receivable and equity method investments, the valuation of derivative financial instruments and the useful lives of long-lived assets. Actual results could differ materially from those estimates.

Fair Value Measurements

Fair Value Measurements. The Company follows the guidance in the Financial Accounting Standards Board Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures, as amended (“Topic 820”), to determine the fair value of financial and non-financial instruments. Topic 820 defines fair value, establishes a framework for measuring fair value in GAAP and expands disclosures about fair value measurements. Topic 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 - quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities; Level 2 - observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 - unobservable inputs, which are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as considering counterparty credit risk. The Company has formally elected to apply the portfolio exception within Topic 820 with respect to measuring counterparty risk for all of its derivative transactions subject to master netting arrangements.

Acquisition, Development and Construction Arrangements

Acquisition, Development and Construction Arrangements. The Company evaluates loans receivable where the Company participates in residual profits through loan provisions or other contracts to ascertain whether the Company has the same risks and rewards as an owner or a joint venture partner. Where the Company concludes that such arrangements are more appropriately treated as an investment in real estate, the Company reflects such loan receivable as an equity investment in real estate under construction in the unaudited condensed consolidated balance sheets. In these cases, no interest income is recorded on the loan receivable and the Company records capitalized interest during the construction period. In arrangements where the Company engages a developer to construct a property or provides funds to a tenant to develop a property, the Company will capitalize the funds provided to the developer/tenant and internal costs of interest and real estate taxes, if applicable, during the construction period.

Reclassifications

Reclassifications. Certain amounts included in the 2012 unaudited condensed consolidated financial statements have been reclassified, primarily relating to discontinued operations, to conform to the 2013 presentation.

Recently Issued Accounting Guidance

Recently Issued Accounting Guidance. In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-02: Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, to improve the transparency of reporting the reclassifications of significant amounts out of accumulated other comprehensive income. This guidance requires entities to present the effects on the line items of net income of significant reclasses from accumulated other comprehensive income, either where net income is presented or in the notes, as well as cross-reference to other disclosures currently required under GAAP for other reclassification items (that are not required under GAAP) to be reclassified directly to net income in their entirety in the same reporting period. The new disclosure requirements are effective for annual reporting periods beginning after December 15, 2012. The new disclosures are required for both interim and annual reporting. The implementation of this guidance did not have an impact on the Company's financial position, results of operations or cash flows.

Fair Value Measurements [Abstract]

Fair Value Disclosures

Fair Value Measurements

The following tables present the Company's assets and liabilities from continuing operations measured at fair value on a recurring and non-recurring basis as of June 30, 2013 and December 31, 2012, aggregated by the level in the fair value hierarchy within which those measurements fall:

	Balance		Fair Value Measurements Using

*Represents a non-recurring fair value measurement.

The table below sets forth the carrying amounts and estimated fair values of the Company's financial instruments as of June 30, 2013 and December 31, 2012.

	As of June 30, 2013				As of December 31, 2012
	Carrying Amount		Fair Value		Carrying Amount		Fair Value

Liabilities
Debt	$	1,778,305	$	1,766,215	$	1,878,208	$	1,835,157

The majority of the inputs used to value the Company's interest rate swaps fall within Level 2 of the fair value hierarchy, such as observable market interest rate curves; however, the credit valuation associated with the interest rate swaps utilizes Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. As of June 30, 2013 and December 31, 2012, the Company determined that the credit valuation adjustment relative to the overall fair value of the interest rate swaps was not significant. As a result, the interest rate swaps have been classified in Level 2 of the fair value hierarchy.

The Company estimates the fair value of its real estate assets by using income and market valuation techniques. The Company may estimate fair values using market information such as broker opinions of value, recent sales data for similar assets or discounted cash flow models, which primarily rely on Level 3 inputs. The cash flow models include estimated cash inflows and outflows over a specified holding period. These cash flows may include contractual rental revenues, projected future rental revenues and expenses and forecasted tenant improvements and lease commissions based upon market conditions determined through discussion with local real estate professionals, experience the Company has with its other owned properties in such markets and expectations for growth. Capitalization rates and discount rates utilized in these models are estimated by management based upon rates that management believes to be within a reasonable range of current market rates for the respective properties based upon an analysis of factors such as property and tenant quality, geographical location and local supply and demand observations. To the extent the Company under estimates forecasted cash outflows (tenant improvements, lease commissions and operating costs) or over estimates forecasted cash inflows (rental revenue rates), the estimated fair value of its real estate assets could be overstated.

The Company estimates the fair values of its loans receivable by using an estimated discounted cash flow analysis using Level 3 inputs consisting of scheduled cash flows and discount rate estimates to approximate those that a willing buyer and seller might use and/or the estimated value of the underlying collateral. The fair value of the Company's debt is estimated by using a discounted cash flow analysis using Level 3 inputs, based upon estimates of market interest rates.

Fair values cannot be determined with precision, may not be substantiated by comparison to quoted prices in active markets and may not be realized upon sale. Additionally, there are inherent uncertainties in any fair value measurement technique, and changes in the underlying assumptions used, including discount rates, liquidity risks and estimates of future cash flows, could significantly affect the fair value measurement amounts.

Cash Equivalents, Restricted Cash, Accounts Receivable and Accounts Payable. The Company estimates that the fair value of cash equivalents, restricted cash, accounts receivable and accounts payable approximates carrying value due to the relatively short maturity of the instruments.

Derivatives Hedging Activities

Derivatives and Hedging Activities

Risk Management Objective of Using Derivatives. The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the type, amount, sources, and duration of its debt funding and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company's derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company's known or expected cash receipts and its known or expected cash payments principally related to the Company's investments and borrowings.

Cash Flow Hedges of Interest Rate Risk. The Company's objectives in using interest rate derivatives are to add stability to interest expense, to manage its exposure to interest rate movements and therefore manage its cash outflows as it relates to the underlying debt instruments. To accomplish these objectives, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy relating to certain of its variable rate debt instruments. 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 agreements without exchange of the underlying notional amount.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings.

The Company has designated the interest-rate swap agreements with its counterparties as cash flow hedges of the risk of variability attributable to changes in the LIBOR swap rate on $319,000 of LIBOR-indexed variable-rate unsecured term loans. Accordingly, changes in the fair value of the swaps are recorded in other comprehensive income (loss) and reclassified to earnings as interest becomes receivable or payable. In January 2012, the Company settled the 2008 interest-rate swap agreement with KeyBank for $3,539. The Company had a credit balance of $1,837 in accumulated other comprehensive income at the settlement date which was amortized into earnings on a straight-line basis through February 2013.

Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on the term loans. During the next 12 months, the Company estimates that an additional $3,316 will be reclassified as an increase to interest expense.

As of June 30, 2013, the Company had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk:

Interest Rate Derivative	Number of Instruments	Notional
Interest Rate Swaps	6	$319,000

The Company's agreements with swap derivative counterparties contain provisions whereby if the Company defaults on the underlying indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default of the swap derivative obligation. As of June 30, 2013, the Company has not posted any collateral related to the agreements.

Loans Receivable

As of June 30, 2013 and December 31, 2012, the Company's loans receivable, including accrued interest and net of origination fees and loan loss reserves were comprised primarily of first and second mortgage loans and mezzanine loans on real estate aggregating $88,994 and $72,540, respectively. The loans bear interest, including imputed interest, at rates ranging from 4.6% to 20.0% and mature at various dates through 2022.

The following is a summary of our loans receivable as of June 30, 2013 and December 31, 2012:

	Loan carrying-value(1)
Loan		6/30/2013		12/31/2012		Interest Rate		Maturity Date
Norwalk, CT(2)		$	20,262	$	3,479	7.50	%	11/2014

Other		2,586		2,836		8.00	%	2021-2022
		$	88,994	$	72,540

(1) Loan carrying value includes accrued interest and is net of origination costs and fee eliminations, if any.

(2) The Company is committed to lend up to $32,600.

(3) The Company is committed to lend up to $10,660.

(4) Loan is in default. The Company has obtained a foreclosure judgment but has not foreclosed as of June 30, 2013. The Company did not record interest income of $1,911 and $2,647 during the six months ended June 30, 2013 and the year ended December 31, 2012, respectively. The Company believes the office property collateral has an estimated fair value in excess of the Company's investment.

The Company has two types of financing receivables: loans receivable and a capitalized financing lease. The Company determined that its financing receivables operate within one portfolio segment as they are within the same industry and use the same impairment methodology. The Company's loans receivable are secured by commercial real estate assets and the capitalized financing lease is for a commercial office property located in Greenville, South Carolina. In addition, the Company assesses all financing receivables for impairment, when warranted, based on an individual analysis of each receivable.

The Company's financing receivables operate within one class of financing receivables as these assets are collateralized by commercial real estate and similar metrics are used to monitor the risk and performance of these assets. The Company's management uses credit quality indicators to monitor financing receivables such as quality of collateral, the underlying tenant's credit rating and collection experience. As of June 30, 2013, the financing receivables were performing as anticipated and there were no significant delinquent amounts outstanding, other than the Schaumburg, Illinois loan as disclosed above.

Debt Disclosure [Abstract]

Debt

The Company had outstanding non-recourse secured mortgages and notes payable of $1,043,934 and $1,415,961 as of June 30, 2013 and December 31, 2012, respectively. Interest rates, including imputed rates on mortgages and notes payable, ranged from 3.6% to 8.5% at June 30, 2013 and December 31, 2012 and the mortgages and notes payables mature between 2013 and 2027 as of June 30, 2013. The weighted-average interest rate at June 30, 2013 and December 31, 2012 was 5.4% and 5.6%, respectively.

In June 2013, the Company issued $250,000 aggregate principal amount of 4.25% Senior Notes due 2023 (“Senior Notes”) at an issuance price of 99.026% of the principal amount. The Senior Notes are unsecured, pay interest semi-annually in arrears and mature in June 2023. The Company may redeem the notes at its option at any time prior to maturity in whole or in part by paying the principal amount of the notes being redeemed plus a premium. The Company issued these Senior Notes at an initial discount of $2,435 which will be recognized as additional interest expense over the term of the Senior Notes. The Senior Notes are rated Baa2 and BBB- by Moody’s Investors Service, Inc. (“Moody’s”) and Standard & Poor’s Rating Services (“S&P”), respectively.

On February 12, 2013, the Company refinanced its $300,000 secured revolving credit facility with a $300,000 unsecured revolving credit facility with KeyBank National Association (“KeyBank”), as agent. The unsecured revolving credit facility matures in February 2017 but can be extended until February 2018 at the Company’s option. The unsecured revolving credit facility bore interest at LIBOR plus 1.50% to 2.05% based on the Company’s leverage ratio, as defined therein. Since the Company has obtained an investment-grade unsecured debt rating from both Moody’s and S&P, the interest rate under the unsecured revolving credit facility ranges from LIBOR plus 0.95% to 1.725% (1.15% as of June 30, 2013) depending on the Company's unsecured debt rating. In addition, the Company increased its availability under the unsecured revolving credit facility from $300,000 to $400,000. At June 30, 2013, the unsecured revolving credit facility had no amounts outstanding, outstanding letters of credit of $7,644 and availability of $392,356, subject to covenant compliance.

In connection with the refinancing discussed above, the Company also procured a five-year $250,000 unsecured term loan facility from KeyBank, as agent. The unsecured term loan matures in February 2018, required regular payments of interest only at interest rates ranging from LIBOR plus 1.45% to 2.00% dependent on the Company's leverage ratio, as defined therein and can be prepaid without penalty. Since the Company has obtained an investment-grade unsecured debt rating from both Moody’s and S&P, the interest rate under the unsecured term loan ranges from LIBOR plus 1.10% to 2.10% (1.35% as of June 30, 2013) depending on the Company’s unsecured debt rating. As of June 30, 2013, the Company entered into an interest-rate swap agreement to fix LIBOR at 0.73% through February 2018 on the $64,000 of outstanding LIBOR-based borrowings.

During 2012, the Company procured a $255,000 secured term loan from Wells Fargo Bank, National Association (“Wells Fargo”), as agent. The term loan matures in January 2019. The term loan required regular payments of interest only at interest rates ranging from LIBOR plus 2.00% to 2.85% dependent on the Company's leverage ratio, as defined therein. Since the Company has obtained an investment-grade unsecured debt rating from both Moody’s and S&P, the interest rate under the secured term loan ranges from LIBOR plus 1.50% to 2.25% (1.75% as of June 30, 2013) depending on the Company's unsecured debt rating. The Company may prepay any outstanding borrowings under the term loan facility at a premium through January 12, 2016 and at par thereafter. During 2012, the Company entered into interest-rate swap agreements to fix LIBOR at a weighted-average rate of 1.42% through January 2019 on the $255,000 of outstanding LIBOR-based borrowings. The term loan was initially secured by ownership interest pledges by certain subsidiaries that collectively owned a borrowing base of properties. In February 2013, the Company amended the term loan to release the collateral as security.

The unsecured revolving credit facility and the unsecured term loans are subject to financial covenants, which the Company was in compliance with at June 30, 2013.

The Company had $25,000 and $35,551 secured term loans with KeyBank, which were satisfied in January 2012 and the Company recognized debt satisfaction charges of $1,578 as a result of the satisfaction.

During 2010, the Company issued $115,000 aggregate principal amount of 6.00% Convertible Guaranteed Notes due 2030. The notes pay interest semi-annually in arrears and mature in January 2030. The holders of the notes may require the Company to repurchase their notes in January 2017, January 2020 and January 2025 for cash equal to 100% of the notes to be repurchased, plus any accrued and unpaid interest. The Company may not redeem any notes prior to January 2017, except to preserve its REIT status. The notes have a current conversion rate of 146.2412 common shares per one thousand principal amount of the notes, representing a conversion price of approximately $6.84 per common share. The conversion rate is subject to adjustment under certain circumstances, including increases in the Company's dividend rate above a certain threshold and the issuance of stock dividends. The notes are convertible by the holders under certain circumstances for cash, common shares or a combination of cash and common shares at the Company's election. The notes are convertible prior to the close of business on the second business day immediately preceding the stated maturity date, at any time beginning in January 2029 and also upon the occurrence of specified events. During the six months ended June 30, 2013, $42,750 aggregate principal amount of the notes were converted for 6,167,111 common shares and aggregate cash payments of $2,663, plus accrued and unpaid interest resulting in aggregate debt satisfaction charges of $10,633.

During 2007, the Company issued an aggregate $450,000 of its 5.45% Exchangeable Guaranteed Notes due 2027. The Company prepaid $387,850 of the notes prior to 2012 and the remaining $62,150 of notes were repurchased by the Company and satisfied in January 2012 pursuant to a holder repurchase option. This resulted in debt satisfaction charges of $44.
