Variable Interest Entity [Line Items]
The Company	The Company Lexington Realty Trust (together with its consolidated subsidiaries, except when the context only applies to the parent entity, the “Company”) is a Maryland statutory real estate investment trust (“REIT”) that owns a diversified portfolio of equity and debt investments in single-tenant commercial properties. As of December 31, 2016 , the Company had equity ownership interests in approximately 195 consolidated properties located in 40 states. The properties in which the Company has an interest are primarily net-leased to tenants in various industries. 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 from which it was previously precluded 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, which are single purpose entities, (2) an operating partnership, Lepercq Corporate Income Fund L.P. (“LCIF”), 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, (3) a wholly-owned TRS, Lexington Realty Advisors, Inc. (“LRA”), and (4) investments in joint ventures. References to “OP Units” refer to units of limited partner interests in LCIF. 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 interest 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. Each property owner subsidiary is a separate legal entity that maintains separate books and records. The assets and credit of each property owner subsidiary with a property subject to a mortgage loan are not available to creditors to satisfy the debt and other obligations of any other person, including any other property owner subsidiary or any other affiliate. Consolidated entities that are not property owner subsidiaries do not directly own any of the assets of a property owner subsidiary (or the general partner, member or managing member of such property owner subsidiary), but merely hold partnership, membership or beneficial interest therein, which interests are subordinate to the claims of such property owner subsidiary's (or its general partner's, member's or managing member's) creditors.

The Company	The Partnership Lepercq Corporate Income Fund L.P. (together with its consolidated subsidiaries, except when the context only applies to the parent entity, the “Partnership”) was organized in 1986 as a limited partnership under the Delaware Revised Uniform Limited Partnership Act. The Partnership's sole general partner, Lex GP-1 Trust (the “General Partner”), is a wholly-owned subsidiary of Lexington Realty Trust (“Lexington”). The Partnership is an operating partnership subsidiary of Lexington. As of December 31, 2016 , Lexington, through Lex LP-1 Trust, a wholly-owned subsidiary, and the General Partner owned approximately 96.0% of the outstanding units of the Partnership. As of December 31, 2016 , the Partnership had equity ownership interests in 33 consolidated real estate properties located in 22 states. The properties in which the Partnership has an interest are primarily net-leased to tenants in various industries. On December 30, 2013, another operating partnership subsidiary of Lexington, Lepercq Corporate Income Fund II L.P. (“LCIF II”) was merged with and into the Partnership, with the Partnership as the surviving entity. In connection with the merger of LCIF II with and into the Partnership, former LCIF II partners representing 170,193 limited partner interests (“OP Units”) elected or were deemed to elect to receive an aggregate amount of $1,962 in cash for the repurchase of such OP units. A majority of the real properties in which the Partnership had an interest are generally subject to net leases or similar leases where the tenant pays 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 operating expenses. Property owner subsidiaries are landlords under leases for properties in which the Partnership has an interest and/or borrows under loan agreements secured by properties in which the Partnership has an interest and lender subsidiaries are lenders under loan agreements where the Partnership made an investment in a loan asset, but in all cases are separate and distinct legal entities. The assets and credit of a property owner subsidiary or lender subsidiary are not available to satisfy the debt and other obligations of any other person, including any other property owner subsidiary or lender subsidiary or any other affiliate.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Consolidation. The Company's 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, partnerships and joint ventures which it controls (i) through voting rights or similar rights or (ii) 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. On January 1, 2016, the Company adopted Accounting Standards Update (“ASU”) 2015-02 (Topic 810), Amendments to the Consolidation Analysis, modifying the analysis it must perform to determine whether it should consolidate certain types of legal entities. The guidance does not amend the existing disclosure requirements for VIEs or voting interest model entities. The adoption of this guidance had no impact on consolidated entities included in the Company's consolidated financial statements as all entities previously consolidated are still consolidated and all entities previously not consolidated are still not consolidated. However, under the revised guidance, the Company determined that certain of its affiliated limited partnerships and similar entities are now considered, by definition, VIEs. These entities were determined to be VIEs as the unaffiliated partners/members did not have simple majority substantive kick-out rights or participating rights. The Company determined that it was the primary beneficiary of certain VIEs as it has a controlling financial interest in these entities. LCIF, which continues to be consolidated and in which the Company has an approximate 96% interest, was determined to be a VIE under this new guidance. See the consolidated financial statements of LCIF included within this Annual Report. The Company has a joint venture limited partnership with a developer which is a consolidated VIE. The joint venture is developing an office campus in Lake Jackson, Texas. The Company currently has a 100% interest in the joint venture; however, the developer has certain protective rights, and, upon project completion, the developer will be credited with a notional capital account for a profit interest and certain cost savings. During 2016, the joint venture completed three of four buildings. As of December 31, 2016 and December 31, 2015 , the joint venture had $55,960 and $62,353 , respectively, in real estate under construction. The assets of each VIE are only available to satisfy such VIE's respective liabilities. As of December 31, 2016 , the VIEs' mortgages and notes payable were non-recourse to the Company. Below is a summary of selected financial data of consolidated VIEs for which the Company is the primary beneficiary included in the Consolidated Balance Sheets as of December 31, 2016 and December 31, 2015 : December 31, 2016 December 31, 2015 Real estate, net $ 778,265 $ 1,072,463 Total assets $ 899,801 $ 1,192,944 Mortgages and notes payable, net $ 364,099 $ 431,599 Total liabilities $ 395,332 $ 448,057 Earnings Per Share . Basic net income (loss) per share is computed by dividing net income (loss) reduced by preferred dividends and amounts allocated to certain non-vested share-based payment awards, if applicable, by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share amounts are similarly computed but include the effect, when dilutive, of in-the-money common share options and non-vested common shares, OP units and put options of certain convertible securities. 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 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 economic environment. The 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, 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, valuation of derivative financial instruments, valuation of compensation plans 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 ("FASB") Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures ("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. Revenue Recognition. The Company recognizes lease revenue on a straight-line basis over the term of the lease unless another systematic and rational basis is more representative of the time pattern in which the use benefit is derived from the leased property. Revenue is recognized on a contractual basis for leases with escalations tied to a consumer price index with no floor. Renewal options in leases with rental terms that are lower than those in the primary term are excluded from the calculation of straight-line rent if the renewals are not reasonably assured. If the Company funds tenant improvements and the improvements are deemed to be owned by the Company, revenue recognition will commence when the improvements are substantially completed and possession or control of the space is turned over to the tenant. If the Company determines that the tenant allowances are lease incentives, the Company commences revenue recognition when possession or control of the space is turned over to the tenant for tenant work to begin. The lease incentive is recorded as a deferred expense and amortized as a reduction of revenue on a straight-line basis over the respective lease term. The Company recognizes lease termination fees as rental revenue in the period received and writes off unamortized lease-related intangible and other lease-related account balances, provided there are no further Company obligations under the lease. Otherwise, such fees and balances are recognized on a straight-line basis over the remaining obligation period with the termination payments being recorded as a component of rent receivable-deferred on the Consolidated Balance Sheets. Gains on sales of real estate are recognized based upon the specific timing of the sale as measured against various criteria related to the terms of the transactions and any continuing involvement associated with the properties. If the sales criteria are not met, the gain is deferred and the finance, installment or cost recovery method, as appropriate, is applied until the sales criteria are met. To the extent the Company sells a property and retains a partial ownership interest in the property, the Company recognizes gain to the extent of the third-party ownership interest. Purchase Accounting and Acquisition of Real Estate. The fair value of the real estate acquired, which includes the impact of fair value adjustments for assumed mortgage debt related to property acquisitions, is allocated to the acquired tangible assets, consisting of land, building and improvements and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, other value of in-place leases and value of tenant relationships, based in each case on their fair values. Acquisition costs are expensed as incurred and are included in property operating expense in the accompanying Consolidated Statement of Operations. The fair value of the tangible assets of an acquired property (which includes land, building and improvements and fixtures and equipment) is determined by valuing the property as if it were vacant. The “as-if-vacant” value is then allocated to land and building and improvements based on management's determination of relative fair values of these assets. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and other operating expenses and estimates of lost rental revenue during the expected lease-up periods based on current market demand. Management also estimates costs to execute similar leases including leasing commissions. In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market lease values are recorded based on the difference between the current in-place lease rent and management's estimate of current market rents. Below-market lease intangibles are recorded as part of deferred revenue and amortized into rental revenue over the non-cancelable periods and bargain renewal periods of the respective leases. Above-market leases are recorded as part of intangible assets and amortized as a direct charge against rental revenue over the non-cancelable portion of the respective leases. The aggregate value of other acquired intangible assets, consisting of in-place leases and tenant relationship values, is measured by the excess of (1) the purchase price paid for a property over (2) the estimated fair value of the property as if vacant, determined as set forth above. This aggregate value is allocated between in-place lease values and tenant relationship values based on management's evaluation of the specific characteristics of each tenant's lease. The value of in-place leases is amortized to expense over the remaining non-cancelable periods and any bargain renewal periods of the respective leases. The value of tenant relationships is amortized to expense over the applicable lease term plus expected renewal periods. Depreciation is determined by the straight-line method over the remaining estimated economic useful lives of the properties. The Company generally depreciates its real estate assets over periods ranging up to 40 years. Impairment of Real Estate. The Company evaluates the carrying value of all tangible and intangible real estate assets held for investment for possible impairment when an event or change in circumstance has occurred that indicates its carrying value may not be recoverable. The evaluation includes estimating and reviewing anticipated future undiscounted cash flows to be derived from the asset. If such cash flows are less than the asset's carrying value, an impairment charge is recognized to the extent by which the asset's carrying value exceeds its estimated fair value, which may be below the balance of any non-recourse financing. Estimating future cash flows and fair values is highly subjective and such estimates could differ materially from actual results. Investments in Non-Consolidated Entities . The Company accounts for its investments in 50% or less owned entities under the equity method, unless consolidation is required. If the Company's investment in the entity is insignificant and the Company has no influence over the control of the entity then the entity is accounted for under the cost method. Impairment of Equity Method Investments. The Company assesses whether there are indicators that the value of its equity method investments may be impaired. An impairment charge is recognized only if the Company determines that a decline in the value of the investment below its carrying value is other-than-temporary. The assessment of impairment is highly subjective and involves the application of significant assumptions and judgments about the Company's intent and ability to recover its investment given the nature and operations of the underlying investment, including the level of the Company's involvement therein, among other factors. To the extent an impairment is deemed to be other-than-temporary, the loss is measured as the excess of the carrying amount of the investment over the estimated fair value of the investment. Loans Receivable. Loans held for investment are intended to be held to maturity and, accordingly, are carried at cost, net of unamortized loan origination costs and fees, loan purchase discounts, and net of an allowance for loan losses when such loan is deemed to be impaired. Loan origination costs and fees and loan purchase discounts are amortized over the term of the loan. The Company considers a loan impaired when, based upon current information and events, it is probable that it will be unable to collect all amounts due for both principal and interest according to the contractual terms of the loan agreement. Significant judgments are required in determining whether impairment has occurred. The Company performs an impairment analysis by comparing either the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's observable current market price or the fair value of the underlying collateral to the net carrying value of the loan, which may result in an allowance and corresponding loan loss charge. Interest income is recorded on a cash basis for impaired loans. 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 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 provide 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. Properties Held For Sale. Assets and liabilities of properties that meet various held for sale criteria, including whether it is probable that a sale will occur within 12 months, are presented separately in the Consolidated Balance Sheets. Commencing January 1, 2015, the operating results of these properties are reflected as discontinued operations in the Consolidated Statements of Operations only if the sale of these assets represents a strategic shift in operations, if not, the operating results are included in continuing operations. Properties classified as held for sale are carried at the lower of net carrying value or estimated fair value less costs to sell and depreciation and amortization are no longer recognized. Properties that do not meet the held for sale criteria are accounted for as operating properties. Deferred Expenses. Deferred expenses consist primarily of revolving line of credit debt and leasing costs. Debt costs are amortized using the straight-line method, which approximates the interest method, over the terms of the debt instruments and leasing costs are amortized over the term of the related lease. Derivative Financial Instruments . The Company accounts for its interest rate swap agreements in accordance with FASB ASC Topic 815, Derivatives and Hedging ("Topic 815"). In accordance with Topic 815, these agreements are carried on the balance sheet at their respective fair values, as an asset if fair value is positive, or as a liability if fair value is negative. If the interest rate swap is designated as a cash flow hedge, the effective portion of the interest rate swap's change in fair value is reported as a component of other comprehensive income (loss); the ineffective portion, if any, is recognized in earnings as an increase or decrease to interest expense. Upon entering into hedging transactions, the Company documents the relationship between the interest rate swap agreement and the hedged item. The Company also documents its risk-management policies, including objectives and strategies, as they relate to its hedging activities. The Company assesses, both at inception of a hedge and on an ongoing basis, whether or not the hedge is highly effective. The Company will discontinue hedge accounting on a prospective basis with changes in the estimated fair value reflected in earnings when (1) it is determined that the derivative is no longer effective in offsetting cash flows of a hedged item (including forecasted transactions), (2) it is no longer probable that the forecasted transaction will occur or (3) it is determined that designating the derivative as an interest rate swap is no longer appropriate. The Company does and may continue to utilize interest rate swap and cap agreements to manage interest rate risk, but does not anticipate entering into derivative transactions for speculative trading purposes. Stock Compensation. The Company maintains an equity participation plan. Non-vested share grants generally vest either based upon (1) time, (2) performance and/or (3) market conditions. Options granted under the plan in 2010 vested over a five -year period and expire ten years from the date of grant. Options granted under the plan in 2008 vested upon attainment of certain market performance measures and expire ten years from the date of grant. All share-based payments to employees, including grants of employee stock options, are recognized in the Consolidated Statements of Operations based on their fair values. Tax Status. The Company has made an election to qualify, and believes it is operating so as to qualify, as a REIT for federal income tax purposes. Accordingly, the Company generally 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 Sections 856 through 860 of the Code. The Company is permitted to participate in certain activities from which it was previously precluded 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 under the Code. As such, the Company is subject to federal and state income taxes on the income from these activities. Income taxes, primarily related to the Company's taxable REIT subsidiaries, are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. Cash and Cash Equivalents. The Company considers all highly liquid instruments with maturities of three months or less from the date of purchase to be cash equivalents. Restricted Cash. Restricted cash is comprised primarily of cash balances held in escrow with lenders. Environmental Matters. Under various federal, state and local environmental laws, statutes, ordinances, rules and regulations, an owner of real property may be liable for the costs of removal or remediation of certain hazardous or toxic substances at, on, in or under such property as well as certain other potential costs relating to hazardous or toxic substances. These liabilities may include government fines, penalties and damages for injuries to persons and adjacent property. Such laws often impose liability without regard to whether the owner knew of, or was responsible for, the presence or disposal of such substances. Although most of the tenants of properties in which the Company has an interest are primarily responsible for any environmental damage and claims related to the leased premises, in the event of the bankruptcy or inability of the tenant of such premises to satisfy any obligations with respect to such environmental liability, or if the tenant is not responsible, the Company's property owner subsidiary may be required to satisfy any such obligations, should they exist. In addition, the property owner subsidiary, as the owner of such a property, may be held directly liable for any such damages or claims irrespective of the provisions of any lease. As of December 31, 2016 , the Company was not aware of any environmental matter relating to any of its investments that would have a material impact on the consolidated financial statements. Segment Reporting. The Company operates generally in one industry segment, single-tenant real estate assets. Reclassifications . Certain amounts included in prior years' financial statements have been reclassified to conform to the current year's presentation. The Company adopted ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, on January 1, 2016. ASU 2015-03 amended presentation guidance by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Prior to the issuance of ASU 2015-03, debt issuance costs were presented as an asset in the balance sheet. As shown in the table below and pursuant to the guidance in ASU 2015-03, the Company has reclassified unamortized debt issuance costs associated with certain debt obligations in the Company's previously reported consolidated balance sheet as of December 31, 2015 as follows: As previously reported December 31, 2015 Reclassifications As adjusted December 31, 2015 Deferred expenses, net $ 63,832 $ (21,832 ) $ 42,000 Mortgages and notes payable, net 882,952 (10,309 ) 872,643 Term loans payable, net 505,000 (4,924 ) 500,076 Senior notes payable, net 497,947 (4,421 ) 493,526 Convertible guaranteed notes payable, net 12,180 (54 ) 12,126 Trust preferred securities, net 129,120 (2,124 ) 126,996 Recently Issued Accounting Guidance . In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the guidance for revenue recognition to eliminate the industry-specific revenue recognition guidance and replace it with a principle based approach for determining revenue recognition. Leases are specifically excluded from this ASU and will be governed by the applicable lease codifications; however, this update may have implications in certain variable payment terms included in lease agreements and in sale and leaseback transactions. The effective date of the new guidance was updated by ASU 2015-14 and is effective for reporting periods beginning after December 15, 2017. The Company will adopt ASU 2014-09 effective January 1, 2018 and anticipates using the modified retrospective with cumulative-effective transition method. The Company is identifying applicable revenue streams and continues to evaluate the impact of the adoption of the new guidance on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize a right of use asset and related lease liability for those leases classified as operating leases at the commencement date that have lease terms of more than 12 months. The accounting applied to lessors under this new guidance is largely unchanged from prior guidance. Lessors in most cases will continue to record operating leases as operating leases and recognize lease income from those leases generally on a straight-line basis over the lease term. The ASU is expected to result in the recognition of a right-to-use asset and related liability to account for our future obligations under our ground lease arrangements for which the Company is the lessee. As of December 31, 2016 , the remaining contractual payments under the Company's ground lease agreements aggregated $53,863 . Additionally, the new ASU will require that the Company capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. ASU 2016-02 will be effective for fiscal years beginning after December 15, 2018, and interim periods within those years, and requires a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements; with early adoption permitted. The Company continues to evaluate the impact of the adoption of the new guidance on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation-Improvements to Employee Share-Based Payment Accounting (Topic 718), which involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period; with early adoption permitted. The Company does not believe this guidance will have a material impact on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Statements, which requires more timely recognition of credit losses associated with financial assets. The ASU is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years; however, early adoption is permitted for fiscal years beginning after December 15, 2018. The Company is currently evaluating the impact of the adoption of the new guidance on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those years; with early adoption permitted. The Company does not believe this guidance will have a material impact on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which clarifies guidance on the classification and presentation of changes in restricted cash. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted, and will be applied retrospectively to all periods presented. Upon adoption, restricted cash balances will be included along with cash and cash equivalents as of the end of the period and beginning of period, respectively, in the Company's consolidated statement of cash flows for all periods presented. Upon adoption, separate line items showing changes in restricted cash balances will be eliminated from the Company's consolidated statement of cash flows. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which clarifies the definition of a business when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The Company expects that acquisitions of real estate or in-substance real estate will not meet the revised definition of a business and thus will be treated as asset acquisitions. In February 2017, the FASB issued ASU 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Topic 610-20), which requires that all entities account for the derecognition of a business in accordance with ASC 810, including instances in which the business is considered in-substance real estate. The ASU is effective for annual periods, and interim periods therein, beginning after December 15, 2017. Early application is permitted. The Company is currently evaluating the impact of the adoption of the new guidance on its consolidated financial statements.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Consolidation. The Partnership's 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 Partnership and its consolidated subsidiaries. The Partnership consolidates its wholly-owned subsidiaries, partnerships and joint ventures which it controls (i) through voting rights or similar rights or (ii) by means other than voting rights if the Partnership is the primary beneficiary of a variable interest entity (“VIE”). Entities which the Partnership does not control and entities which are VIEs in which the Partnership is not the primary beneficiary are accounted for under appropriate GAAP. Earnings Per Unit . Net income (loss) per unit is computed by dividing net income (loss) by the weighted-average number of units outstanding during the period. There are no potential dilutive securities. Unit Redemptions . The Partnership's limited partner units that are issued and outstanding, other than those held by Lexington, are currently redeemable at certain times, only at the option of the holders, for Lexington shares of beneficial interests, par value $0.0001 per share classified as common stock (“common shares”), on a one to approximately 1.13 basis, subject to future adjustments. These units are not otherwise mandatorily redeemable by the Partnership. As of December 31, 2016 , Lexington's common shares had a closing price of $10.80 per share. The estimated fair value of these units was $40,734 , assuming all outstanding limited partner units not held by Lexington were redeemed on such date. Allocation of Overhead Expenses . The Partnership does not pay a fee to the General Partner for the day-to-day management of the Partnership. Certain expenses incurred by the General Partner and its affiliates, including Lexington, such as corporate-level interest, amortization of deferred loan costs, payroll and general and administrative expenses are allocated to the Partnership and reimbursed to the General Partner in accordance with the Partnership's partnership agreement. The allocation is based upon gross rental revenues. Distributions; Allocations of Income and Loss . As provided in the Partnership's partnership agreement, distributions and income and loss for financial reporting purposes are allocated to the partners based on their ownership of units. Special allocation rules included in the partnership agreement affect the allocation of taxable income and loss. The Partnership paid or accrued gross distributions of $66,815 ( $0.80 per weighted average unit), $60,846 ( $0.84 per weighted-average unit) and $56,178 ( $0.82 per weighted-average unit) to its partners during the years ended December 31, 2016 , 2015 and 2014 , respectively. Certain units owned indirectly by Lexington are entitled to distributions of $3.25 per unit. Use of Estimates. The Partnership 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 consolidated financial statements in conformity with GAAP. These estimates and assumptions are based on management's best estimates and judgment. The Partnership evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the economic environment. The economic environment has increased the degree of uncertainty inherent in these estimates and assumptions. The Partnership adjusts such estimates when facts and circumstances dictate. The most significant estimates made include the recoverability of accounts receivable, 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 and the useful lives of long-lived assets. Actual results could differ materially from those estimates. Fair Value Measurements. The Partnership follows the guidance in the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures ("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 Partnership 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 counter-party credit risk. Revenue Recognition. The Partnership recognizes lease revenue on a straight-line basis over the term of the lease unless another systematic and rational basis is more representative of the time pattern in which the use benefit is derived from the leased property. Revenue is recognized on a contractual basis for leases with escalations tied to a consumer price index with no floor. Renewal options in leases with rental terms that are lower than those in the primary term are excluded from the calculation of straight-line rent if the renewals are not reasonably assured. If the Partnership funds tenant improvements and the improvements are deemed to be owned by the Partnership, revenue recognition will commence when the improvements are substantially completed and possession or control of the space is turned over to the tenant. If the Partnership determines that the tenant allowances are lease incentives, the Partnership commences revenue recognition when possession or control of the space is turned over to the tenant for tenant work to begin. The lease incentive is recorded as a deferred expense and amortized as a reduction of revenue on a straight-line basis over the respective lease term. The Partnership recognizes lease termination fees as rental revenue in the period received and writes off unamortized lease-related intangible and other lease-related account balances, provided there are no further Partnership obligations under the lease. Otherwise, such fees and balances are recognized on a straight-line basis over the remaining obligation period with the termination payments being recorded as a component of rent receivable-deferred on the Consolidated Balance Sheets. Gains on sales of real estate are recognized based upon the specific timing of the sale as measured against various criteria related to the terms of the transactions and any continuing involvement associated with the properties. If the sales criteria are not met, the gain is deferred and the finance, installment or cost recovery method, as appropriate, is applied until the sales criteria are met. To the extent the Partnership sells a property and retains a partial ownership interest in the property, the Partnership recognizes gain to the extent of the third-party ownership interest. Purchase Accounting and Acquisition of Real Estate. The fair value of the real estate acquired, which includes the impact of fair value adjustments for assumed mortgage debt related to property acquisitions, is allocated to the acquired tangible assets, consisting of land, building and improvements and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, other value of in-place leases and value of tenant relationships, based in each case on their fair values. Acquisition costs are expensed as incurred and are included in property operating expense in the accompanying Consolidated Statement of Operations. The fair value of the tangible assets of an acquired property (which includes land, building and improvements and fixtures and equipment) is determined by valuing the property as if it were vacant. The “as-if-vacant” value is then allocated to land and building and improvements based on management's determination of relative fair values of these assets. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and other operating expenses and estimates of lost rental revenue during the expected lease-up periods based on current market demand. The Partnership also estimates costs to execute similar leases including leasing commissions. In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market lease values are recorded based on the difference between the current in-place lease rent and the Partnership's estimate of current market rents. Below-market lease intangibles are recorded as part of deferred revenue and amortized into rental revenue over the non-cancelable periods and bargain renewal periods of the respective leases. Above-market leases are recorded as part of intangible assets and amortized as a direct charge against rental revenue over the non-cancelable portion of the respective leases. The aggregate value of other acquired intangible assets, consisting of in-place leases and tenant relationship values, is measured by the excess of (1) the purchase price paid for a property over (2) the estimated fair value of the property as if vacant, determined as set forth above. This aggregate value is allocated between in-place lease values and tenant relationship values based on management's evaluation of the specific characteristics of each tenant's lease. The value of in-place leases is amortized to expense over the remaining non-cancelable periods and any bargain renewal periods of the respective leases. The value of tenant relationships are amortized to expense over the applicable lease term plus expected renewal periods. Depreciation is determined by the straight-line method over the remaining estimated economic useful lives of the properties. The Partnership generally depreciates its real estate assets over periods ranging up to 40 years. Impairment of Real Estate. The Partnership evaluates the carrying value of all tangible and intangible real estate assets held for investment for possible impairment when an event or change in circumstance has occurred that indicates its carrying value may not be recoverable. The evaluation includes estimating and reviewing anticipated future undiscounted cash flows to be derived from the asset. If such cash flows are less than the asset's carrying value, an impairment charge is recognized to the extent by which the asset's carrying value exceeds the estimated fair value, which may be below the balance of any non-recourse financing. Estimating future cash flows and fair values is highly subjective and such estimates could differ materially from actual results. Investments in Non-Consolidated Entities . The Partnership accounts for its investments in 50% or less owned entities under the equity method, unless consolidation is required. If the Partnership's investment in the entity is insignificant and the Partnership has no influence over the control of the entity then the entity is accounted for under the cost method. Impairment of Equity Method Investments. The Partnership assesses whether there are indicators that the value of its equity method investments may be impaired. An impairment charge is recognized only if the Partnership determines that a decline in the value of the investment below its carrying value is other-than-temporary. The assessment of impairment is highly subjective and involves the application of significant assumptions and judgments about the Partnership's intent and ability to recover its investment given the nature and operations of the underlying investment, among other factors. To the extent an impairment is deemed to be other-than-temporary, the loss is measured as the excess of the carrying amount of the investment over the estimated fair value of the investment. Properties Held For Sale. Assets and liabilities of properties that meet various held for sale criteria, including whether it is probable that a sale will occur within 12 months, are presented separately in the Consolidated Balance Sheets. Commencing January 1, 2015, the operating results of these properties are reflected as discontinued operations in the Consolidated Statements of Operations only if the sale of these assets represents a strategic shift in operations, if not, the operating results are included in continuing operations. Properties classified as held for sale are carried at the lower of net carrying value or estimated fair value less costs to sell and depreciation and amortization are no longer recognized. Properties that do not meet the held for sale criteria are accounted for as operating properties. Acquisition, Development and Construction Arrangements. The Partnership evaluates loans receivable where the Partnership participates in residual profits through loan provisions or other contracts to ascertain whether the Partnership has the same risks and rewards as an owner or a joint venture partner. Where the Partnership concludes that such arrangements are more appropriately treated as an investment in real estate, the Partnership reflects such loan receivable as an equity investment in real estate under construction in the Consolidated Balance Sheets. In these cases, no interest income is recorded on the loan receivable and the Partnership records capitalized interest during the construction period. In arrangements where the Partnership engages a developer to construct a property or provide funds to a tenant to develop a property, the Partnership will capitalize the funds provided to the developer/tenant and internal costs of interest and real estate taxes, if applicable, during the construction period. Deferred Expenses. Deferred expenses consist primarily of leasing costs, which are amortized over the term of the related lease. Income Taxes. Because the Partnership is a limited partnership, taxable income or loss of the Partnership is reported in the income tax returns of its partners. Accordingly, no provision for income taxes is made in the Consolidated Financial Statements of the Partnership. However, the Partnership is required to pay certain state and local entity level taxes which are expensed as incurred. The Partnership does not have any unrecognized tax benefits or any additional tax liabilities as of December 31, 2016 and 2015 . Cash and Cash Equivalents. The Partnership considers all highly liquid instruments with maturities of three months or less from the date of purchase to be cash equivalents. Restricted Cash. Restricted cash is comprised primarily of cash balances held in escrow with lenders. Co-borrower Debt. In February 2013, the FASB issued Accounting Standards Update (“ASU”) 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date (“ASU 2013-04”), requiring recognition of such obligations as the sum of (a) the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and (b) any additional amount the reporting entity expects to pay on behalf of its co-obligors. Environmental Matters. Under various federal, state and local environmental laws, statutes, ordinances, rules and regulations, an owner of real property may be liable for the costs of removal or remediation of certain hazardous or toxic substances at, on, in or under such property as well as certain other potential costs relating to hazardous or toxic substances. These liabilities may include government fines, penalties and damages for injuries to persons and adjacent property. Such laws often impose liability without regard to whether the owner knew of, or was responsible for, the presence or disposal of such substances. Although most of the tenants of properties in which the Partnership has an interest are primarily responsible for any environmental damage and claims related to the leased premises, in the event of the bankruptcy or inability of the tenant of such premises to satisfy any obligations with respect to such environmental liability, or if the tenant is not responsible, the Partnership's property owner subsidiary may be required to satisfy any such obligations, should they exist. In addition, the property owner subsidiary, as the owner of such a property, may be held directly liable for any such damages or claims irrespective of the provisions of any lease. As of December 31, 2016 , the Partnership was not aware of any environmental matter relating to any of its investments that would have a material impact on the consolidated financial statements. Segment Reporting. The Partnership operates generally in one industry segment, single-tenant real estate assets. Reclassifications . Certain amounts included in prior years' financial statements have been reclassified to conform to the current year's presentation. The Partnership adopted ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs on January 1, 2016. ASU 2015-03 amended presentation guidance by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Prior to the issuance of ASU 2015-03, debt issuance costs were presented as an asset in the balance sheet. As shown in the table below, pursuant to the guidance in ASU 2015-03, the Partnership has reclassified unamortized debt issuance costs associated with certain debt obligations in the Partnership's previously reported Consolidated Balance Sheet as of December 31, 2015 as follows: As previously reported December 31, 2015 Reclassifications As adjusted December 31, 2015 Deferred expenses, net $ 14,352 $ (5,893 ) $ 8,459 Mortgages and notes payable, net 437,492 (5,893 ) 431,599 Recently Issued Accounting Guidance. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the guidance for revenue recognition to eliminate the industry-specific revenue recognition guidance and replace it with a principle based approach for determining revenue recognition. The effective date of the new guidance was updated by ASU 2015-14 and is effective for reporting periods beginning after December 15, 2017. The Partnership will adopt ASU 2014-09 effective January 1, 2018 and anticipates using the modified retrospective with cumulative-effective transition method. The Partnership is identifying applicable revenue streams and continues to evaluate the impact of the adoption of the new guidance on its consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810) - Amendments to the Consolidation Analysis,” which provides guidance on the consolidation evaluation for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. In accordance with the guidance, all legal entities are subject to reevaluation under the revised consolidation model. The guidance was effective in the first quarter of fiscal 2016. The adoption of this guidance did not have an impact on the Partnership. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize a right of use asset and related lease liability for those leases classified as operating leases at the commencement date and have lease terms of more than 12 months. The accounting applied to lessors under this new guidance is largely unchanged from prior guidance. Lessors in most cases will continue to record operating leases as operating leases and recognize lease income from these leases generally on a straight-line basis over the lease term. The ASU is expected to result in the recognition of a right-to-use asset and related liability to account for our future obligations under our ground lease arrangements for which the Partnership is the lessee. As of December 31, 2016 , the remaining contractual payments under the Partnership's ground lease agreements aggregated $3,810 . Additionally, the new ASU will require that the Partnership capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, and requires a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early adoption is permitted. The Partnership continues to evaluate the impact of the adoption of the new guidance on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those years; however early adoption is permitted. The Partnership does not believe this guidance will have a material impact on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which clarifies guidance on the classification and presentation of changes in restricted cash. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted, and will be applied retrospectively to all periods presented. Upon adoption, restricted cash balances will be included along with cash and cash equivalents as of the end of the period and beginning of period, respectively, in the Partnership's consolidated statement of cash flows for all periods presented. Upon adoption, separate line items showing changes in restricted cash balances will be eliminated from the Partnership's consolidated statement of cash flows. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which clarifies the definition of a business when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The Partnership expects that acquisitions of real estate or in-substance real estate will not meet the revised definition of a business and thus will be treated as asset acquisitions. In February 2017, the FASB issued ASU 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Topic 610-20), which requires that all entities account for the derecognition of a business in accordance with ASC 810, including instances in which the business is considered in-substance real estate. The ASU is effective for annual periods, and interim periods therein, beginning after December 15, 2017. Early application is permitted. The Partnership is currently evaluating the impact of the adoption of the new guidance on its consolidated financial statements.

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 each of the years in the three-year period ended December 31, 2016 : 2016 2015 2014 BASIC Income from continuing operations attributable to common shareholders $ 89,109 $ 103,418 $ 37,652 Income from discontinued operations attributable to common shareholders — 1,682 48,672 Net income attributable to common shareholders $ 89,109 $ 105,100 $ 86,324 Weighted-average number of common shares outstanding 233,633,058 233,455,056 228,966,253 Income per common share: Income from continuing operations $ 0.38 $ 0.44 $ 0.17 Income from discontinued operations — 0.01 0.21 Net income attributable to common shareholders $ 0.38 $ 0.45 $ 0.38 2016 2015 2014 DILUTED: Income from continuing operations attributable to common shareholders $ 89,109 $ 103,418 $ 37,652 Impact of assumed conversions (159 ) — — Income from continuing operations attributable to common shareholders 88,950 103,418 37,652 Income from discontinued operations attributable to common shareholders — 1,682 48,672 Impact of assumed conversions: — — — Income from discontinued operations attributable to common shareholders — 1,682 48,672 Net income attributable to common shareholders $ 88,950 $ 105,100 $ 86,324 Weighted-average common shares outstanding - basic 233,633,058 233,455,056 228,966,253 Effect of dilutive securities: Share options 230,352 296,719 470,455 Operating Partnership Units 3,815,621 — — Weighted-average common shares outstanding - diluted 237,679,031 233,751,775 229,436,708 Income per common share: Income from continuing operations $ 0.37 $ 0.44 $ 0.17 Income from discontinued operations — 0.01 0.21 Net income attributable to common shareholders $ 0.37 $ 0.45 $ 0.38 For per common share amounts, all incremental shares are considered anti-dilutive for periods that have a loss from continuing operations attributable to common shareholders. In addition, other common share equivalents may be anti-dilutive in certain periods.

Loans Receivable, Net [Abstract]
Loans Receivable	Loans Receivable As of December 31, 2016 and 2015 , the Company's loans receivable were comprised primarily of mortgage loans on real estate. The following is a summary of our loans receivable as of December 31, 2016 and 2015 : Loan carrying value (1) Loan 12/31/2016 12/31/2015 Interest Rate Maturity Date Kennewick, WA (2) $ 85,709 $ 85,505 9.00 % 05/2022 Oklahoma City, OK (3) 8,501 8,501 11.50 % 03/2016 Other (4) — 1,865 8.00 % 2021-2022 $ 94,210 $ 95,871 (1) Loan carrying value includes accrued interest and is net of origination costs. (2) Loan provides for a current pay rate of 8.75% , an accrual rate of 9% and a balloon of $87,245 at maturity. This loan was in covenant default as of December 31, 2016 . (3) In 2015, the Company loaned a tenant-in-common $8,420 . The loan is secured by the tenant-in-common's interest in an office property in which the Company has a 40% interest. The loan was in monetary default as of December 31, 2016 and the Company is exercising its remedies. (4) In 2016, the Company received $1,583 in full satisfaction of these loans and recognized a $41 impairment charge. As of December 31, 2016 , the Company had one type of financing receivable, loans receivable secured by interests in commercial real estate. The Company determined that its financing receivables operated within one portfolio segment as they were both within the same industry and use the same impairment methodology. In addition, the Company assesses all financing receivables for impairment, when warranted, based on an individual analysis of each receivable. The Company had a capitalized financing lease for a property located in Greenville, South Carolina, which was sold in 2014 for net proceeds of $11,491 . The Company's financing receivables operate within one class of financing receivables as these assets (1) are collateralized by commercial real estate and (2) 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 December 31, 2016 , the financing receivables were performing as anticipated and there were no significant delinquent amounts outstanding, other than the maturity default of the borrower of the Oklahoma City, Oklahoma loan, for which the Company believes its collateral is sufficient to recover the full amount of the receivable. During 2015, the Company acquired the office property collateral from the borrowers in Westmont, Illinois and Southfield, Michigan on two loans receivable that were impaired. In 2014, the Company recognized a $2,500 loan loss on the loan receivable collateralized by the Southfield, Michigan property. Also in 2015 and 2014, the Company recognized aggregate interest income relating to these impaired loans of $14 and $1,752 , respectively. The Company sold the Westmont, Illinois property in 2016.

Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items]
Fair Value Measurements	Fair Value Measurements The following tables present the Company's assets and liabilities measured at fair value on a recurring and non-recurring basis as of December 31, 2016 and 2015 , aggregated by the level in the fair value hierarchy within which those measurements fall: Fair Value Measurements Using Description 2016 (Level 1) (Level 2) (Level 3) Interest rate swap assets $ 44 $ — $ 44 $ — Impaired real estate assets* $ 15,801 $ — $ — $ 15,801 Interest rate swap liabilities $ (1,077 ) $ — $ (1,077 ) $ — *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 December 31, 2016 and 2015 : As of December 31, 2016 As of December 31, 2015 Carrying Amount Fair Value Carrying Amount Fair Value Assets Loans Receivable $ 94,210 $ 94,911 $ 95,871 $ 103,014 Liabilities Debt $ 1,860,598 $ 1,814,824 $ 2,182,367 $ 2,164,571 The majority of the inputs used to value the Company's interest rate swap assets (liabilities) 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 swap assets (liabilities) 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 December 31, 2016 and 2015 , the Company determined that the credit valuation adjustment relative to the overall interest rate swap assets (liabilities) is not significant. As a result, all interest rate swap assets (liabilities) have been classified in Level 2 of the fair value hierarchy. The Company estimates the fair value of its real estate assets, including non-consolidated 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 sale offers 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 utilizing Level 3 inputs by using an estimated discounted cash flow analysis 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 primarily estimated utilizing Level 3 inputs by using a discounted cash flow analysis, based upon estimates of market interest rates. The Company determines the fair value of its Senior Notes and 6.00% Convertible Guaranteed Notes using market prices. The inputs used in determining the fair value of these notes are categorized as Level 1 due to the fact that the Company uses quoted market rates to value these instruments. However, the inputs used in determining the fair value could be categorized as Level 2 if trading volumes are low. 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and 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 did not incur any ineffectiveness during 2016 , 2015 and 2014 . 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 rates on $505,000 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. During 2015, the Company extended the maturity date of the $505,000 of LIBOR indexed variable rate unsecured term loans to August 2020 ( $250,000 ) and January 2021 ( $255,000 ). The extension of these term loans had no impact on the effectiveness of the corresponding cash flow hedges. Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on the aggregate $505,000 term loans. During the next 12 months, the Company estimates that an additional $1,462 will be reclassified as an increase to interest expense if the swaps remain outstanding. As of December 31, 2016 , 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 10 $505,000 The table below presents the fair value of the Company's derivative financial instruments as well as their classification on the Consolidated Balance Sheets as of December 31, 2016 and 2015 .

As of December 31, 2016 , the Company had not posted any collateral related to the agreements.

Equity	Equity Shareholders' Equity: During 2016 , 2015 and 2014 , the Company issued 577,823 , 2,266,191 and 2,600,795 common shares, respectively, under its direct share purchase plan, which includes a dividend reinvestment component, raising net proceeds of approximately $4,115 , $20,797 and $25,813 respectively. During 2013, the Company implemented, and in 2016, the Company updated, its At-The-Market offering program under which the Company may issue up to $125,000 in common shares over the term of this program. During 2016, the Company issued 976,109 common shares under this program and generated aggregate gross proceeds of $10,498 . No shares were sold under this program in 2015 or 2014. The proceeds from these issuances were primarily used for general working capital, to fund investments and retire indebtedness. The Company had 1,935,400 shares of Series C Cumulative Convertible Preferred Stock (“Series C Preferred”), outstanding at December 31, 2016 . The shares have a dividend of $3.25 per share per annum, have a liquidation preference of $96,770 , and the Company, if certain common share prices are achieved, can force conversion into common shares of the Company. As of December 31, 2016 , each share is currently convertible into 2.4339 common shares. This conversion ratio may increase over time if the Company's common share dividend exceeds certain quarterly thresholds. If certain fundamental changes occur, holders may require the Company, in certain circumstances, to repurchase all or part of their shares of Series C Preferred. In addition, upon the occurrence of certain fundamental changes, the Company will, under certain circumstances, increase the conversion rate by a number of additional common shares or, in lieu thereof, may in certain circumstances elect to adjust the conversion rate upon the shares of Series C Preferred becoming convertible into shares of the public acquiring or surviving company. The Company may, at the Company's option, cause shares of Series C Preferred to be automatically converted into that number of common shares that are issuable at the then prevailing conversion rate. The Company may exercise its conversion right only if, at certain times, the closing price of the Company's common shares equals or exceeds 125% of the then prevailing conversion price of the Series C Preferred. Investors in shares of Series C Preferred generally have no voting rights, but will have limited voting rights if the Company fails to pay dividends for six or more quarters and under certain other circumstances. Upon conversion, the Company may choose to deliver the conversion value to investors in cash, common shares, or a combination of cash and common shares. During 2016 , 2015 and 2014 , the Company issued 1,084,835 , 860,730 and 37,678 of its common shares, respectively, to certain employees and trustees. Typically, trustee share grants vest immediately. Employee share grants generally vest ratably, on anniversaries of the grant date, however, in certain situations vesting is cliff-based after a specific number of years and/or subject to meeting certain performance criteria (see note 15). In July 2015, the Company's Board of Trustees authorized the repurchase of up to 10,000,000 common shares. This share repurchase program has no expiration date. During 2016 and 2015, the Company repurchased 1,184,113 and 2,216,799 common shares, respectively, at an average gross price of $7.56 and $8.29 , respectively, per common share under this share repurchase program. Accumulated other comprehensive loss as of December 31, 2016 and 2015 represented $(1,033) and $(1,939) , respectively, of unrealized gain on interest rate swaps, net.

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 2014, in connection with the merger of LCIF II with and into LCIF, former LCIF II partners representing 170,193 OP units elected or were deemed to elect to receive $1,962 in aggregate cash for such OP units. During 2016 , 2015 and 2014 , 48,549 , 32,780 and 29,086 common shares, respectively, were issued by the Company, in connection with OP unit redemptions, for an aggregate value of $210 , $165 and $148 , respectively. As of December 31, 2016 , there were approximately 3,350,000 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.

Employee Benefits and Share-based Compensation [Abstract]
Benefit Plans	Benefit Plans The Company maintains an equity award plan pursuant to which qualified and non-qualified options may be issued. No common share options were issued in 2016 , 2015 and 2014 . The Company granted 1,248,501 , 1,265,500 and 2,000,000 common share options on December 31, 2010 (“2010 options”), January 8, 2010 (“2009 options”) and December 31, 2008 (“2008 options”), respectively, at an exercise price of $7.95 , $6.39 and $5.60 , respectively. The 2010 options (1) vested 20% annually on each December 31, 2011 through 2015 and (2) terminate on the earlier of (x) six months of termination of service with the Company and (y) December 31, 2020. The 2009 options (1) vested 20% annually on each December 31, 2010 through 2014 and (2) terminate on the earlier of (x) six months of termination of service with the Company and (y) December 31, 2019. The 2008 options (1) vested 50% following a 20 -day trading period where the average closing price of a common share of the Company on the New York Stock Exchange (“NYSE”) was $8.00 or higher and vested 50% following a 20 -day trading period where the average closing price of a common share of the Company on the NYSE was $10.00 or higher, and (2) terminate on the earlier of (x) termination of service with the Company or (y) December 31, 2018. As a result of the share dividends paid in 2009, each of the 2008 options is exchangeable for approximately 1.13 common shares at an exercise price of $4.97 per common share. The Company engaged third parties to value the options as of each option's respective grant date. The third parties determined the value to be $2,422 and $2,771 for the 2010 options and 2009 options, respectively, using the Black-Scholes model and $2,480 for the 2008 options using the Monte Carlo model. The options are considered equity awards as they are settled through the issuance of common shares. As such, the options were valued as of the grant date and do not require subsequent remeasurement. There were several assumptions used to fair value the options including the expected volatility in the Company's common share price based upon the fluctuation in the Company's historical common share price. The more significant assumptions underlying the determination of fair value for options granted were as follows: 2010 Options 2009 Options 2008 Options Weighted-average fair value of options granted $ 1.94 $ 2.19 $ 1.24 Weighted-average risk-free interest rate 2.54 % 3.29 % 1.33 % Weighted-average expected option lives (in years) 6.50 6.70 3.60 Weighted-average expected volatility 49.00 % 59.08 % 59.94 % Weighted-average expected dividend yield 7.40 % 6.26 % 14.40 % The Company recognized compensation expense relating to these options over an average of 5.0 years for the 2010 options and 2009 options and 3.6 years for the 2008 options. The Company recognized $480 and $1,038 in compensation expense in 2015 and 2014 , respectively. All deferred compensation costs relating to the outstanding options were fully amortized by December 31, 2015. The intrinsic value of an option is the amount by which the market value of the underlying common share at the date the option is exercised exceeds the exercise price of the option. No options were exercised in 2015 and the total intrinsic value of options exercised for the years ended December 31, 2016 and 2014 were $2,856 and $2,780 , respectively. Share option activity during the years indicated is as follows: Number of Shares Weighted-Average Exercise Price Per Share Balance at December 31, 2013 1,955,701 $ 6.95 Exercised (594,791 ) 6.71 Forfeited (10,500 ) 7.46 Balance at December 31, 2014 and 2015 1,350,410 7.05 Exercised (944,169 ) 7.17 Balance at December 31, 2016 406,241 $ 6.78 As of December 31, 2016 , the aggregate intrinsic value of options that were outstanding and exercisable was $1,632 .

Dividends will not be paid on these grants until earned. Once the performance criteria are met and the actual number of shares earned is determined, such shares vest immediately. (2) The fair value of grants was determined at the grant date using a Monte Carlo simulation model. (3) The shares vest ratably over a three -year service period. (4) Annual grant and shares vested upon grant. As of December 31, 2016 , of the remaining 3,151,310 non-vested shares, 1,693,855 are subject to time-based vesting and 1,457,455 are subject to performance-based vesting. At December 31, 2016 , there are 2,344,136 awards available for grant. The Company has $11,128 in unrecognized compensation costs relating to the non-vested shares that will be charged to compensation expense over an average of approximately 2.8 years. The Company has established a trust for certain officers in which vested common shares granted for the benefit of the officers are deposited. The officers exert no control over the common shares in the trust and the common shares are available to the general creditors of the Company. As of December 31, 2016 and 2015 , there were 427,531 common shares in the trust. The Company sponsors a 401(k) retirement savings plan covering all eligible employees. The Company makes a discretionary matching contribution on a portion of employee participant salaries and, based on its profitability, may make an additional discretionary contribution at each fiscal year end to all eligible employees. These discretionary contributions are subject to vesting under a schedule providing for 25% annual vesting starting with the first year of employment and 100% vesting after four years of employment. Approximately $357 , $333 and $299 of contributions are applicable to 2016 , 2015 and 2014 , respectively. During 2016 , 2015 and 2014 , the Company recognized $8,415 , $8,201 and $7,550 , respectively, in expense relating to scheduled vesting and issuance of common share grants.

Income taxes have been provided for on the asset and liability method. Under the asset and liability method, deferred income taxes are recognized for the temporary differences between the financial reporting basis and the tax basis of assets and liabilities.

The Company is obligated under certain tenant leases, including its proportionate share for leases for non-consolidated entities, 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. The Company and LCIF are parties to a funding agreement under which the Company may be required to fund distributions made on account of LCIF's OP units. Pursuant to the funding agreement, the parties agreed that, if LCIF does not have sufficient cash available to make a quarterly distribution to its limited partners in an amount in accordance with the partnership agreement, Lexington will fund the shortfall. Payments under the agreement will be made in the form of loans to LCIF and will bear interest at prevailing rates as determined by the Company in its discretion but, no less than the applicable federal rate. LCIF's right to receive these loans will expire if no OP units remain outstanding and all such loans repaid. No amounts have been advanced under this agreement. From time to time, the Company is directly or 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. GSMSC II 2006-GG6 Bridgewater Hills Corporate Center, LLC v. Lexington Realty Trust (Supreme Court of the State of New York, County of New York-Index No. 653117/2015) On September 16, 2015, GSMSC II 2006-GG6 Bridgewater Hills Corporate Center, LLC commenced an action as lender against the Company based on a limited guaranty of recourse obligations executed by a predecessor entity of the Company in connection with a mortgage loan secured by a property owner subsidiary's commercial property in Bridgewater, New Jersey. The property owner subsidiary defaulted due to non-payment after the sole tenant vacated at the end of the lease term. The lender currently seeks approximately $9,200 in order to satisfy the outstanding amount of the loan after offset for the lender's asserted value of the property it obtained in foreclosure, plus interest, reasonable attorney’s fees and other costs and disbursements related thereto. The Company had not recorded any liability relating to this litigation as of December 31, 2016 as the Company believes that a loss contingency is "reasonably possible" (as defined by FASB ASC 450-20-20) but not "probable" (as defined by FASB ASC 450-20-20). The lender claims that the Company's limited guaranty was triggered due to the merger of Newkirk Realty Trust, Inc. and Lexington Corporate Properties Trust on December 31, 2006, arguing that it constituted an event of default because it was a transfer that was not permitted by the loan agreement. The limited guaranty provides that the guarantor's liability for the guaranteed obligations shall not exceed $10,000 , which the Company believes is its maximum exposure to loss. The Company intends to vigorously defend the lender’s claim. The Company filed a motion to dismiss, which was generally denied. The Company is currently conducting discovery, with document production required to be completed by March 31, 2017 , fact depositions to be completed by August 28, 2017 and expert dispositions to be completed by October 31, 2017 . Other . Four of the Company's executive officers have employment contracts and are entitled to severance benefits upon termination by the Company without cause or termination by the executive officer with good reason, in each case, as defined in the employment contract. In addition, the Company's other two executive officers and certain other members of the Company's senior management are entitled to severance benefits upon the same events.

Summary of Significant Accoun32

Summary of Significant Accounting Policies (Policies)	12 Months Ended

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation. The Company's 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, partnerships and joint ventures which it controls (i) through voting rights or similar rights or (ii) 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.
Variable Interest Entity	On January 1, 2016, the Company adopted Accounting Standards Update (“ASU”) 2015-02 (Topic 810), Amendments to the Consolidation Analysis, modifying the analysis it must perform to determine whether it should consolidate certain types of legal entities. The guidance does not amend the existing disclosure requirements for VIEs or voting interest model entities. The adoption of this guidance had no impact on consolidated entities included in the Company's consolidated financial statements as all entities previously consolidated are still consolidated and all entities previously not consolidated are still not consolidated. However, under the revised guidance, the Company determined that certain of its affiliated limited partnerships and similar entities are now considered, by definition, VIEs. These entities were determined to be VIEs as the unaffiliated partners/members did not have simple majority substantive kick-out rights or participating rights. The Company determined that it was the primary beneficiary of certain VIEs as it has a controlling financial interest in these entities. LCIF, which continues to be consolidated and in which the Company has an approximate 96% interest, was determined to be a VIE under this new guidance.
Earnings Per Share	Earnings Per Share . Basic net income (loss) per share is computed by dividing net income (loss) reduced by preferred dividends and amounts allocated to certain non-vested share-based payment awards, if applicable, by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share amounts are similarly computed but include the effect, when dilutive, of in-the-money common share options and non-vested common shares, OP units and put options of certain convertible securities
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 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 economic environment. The 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, 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, valuation of derivative financial instruments, valuation of compensation plans 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 ("FASB") Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures ("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.
Revenue Recognition	Revenue Recognition. The Company recognizes lease revenue on a straight-line basis over the term of the lease unless another systematic and rational basis is more representative of the time pattern in which the use benefit is derived from the leased property. Revenue is recognized on a contractual basis for leases with escalations tied to a consumer price index with no floor. Renewal options in leases with rental terms that are lower than those in the primary term are excluded from the calculation of straight-line rent if the renewals are not reasonably assured. If the Company funds tenant improvements and the improvements are deemed to be owned by the Company, revenue recognition will commence when the improvements are substantially completed and possession or control of the space is turned over to the tenant. If the Company determines that the tenant allowances are lease incentives, the Company commences revenue recognition when possession or control of the space is turned over to the tenant for tenant work to begin. The lease incentive is recorded as a deferred expense and amortized as a reduction of revenue on a straight-line basis over the respective lease term. The Company recognizes lease termination fees as rental revenue in the period received and writes off unamortized lease-related intangible and other lease-related account balances, provided there are no further Company obligations under the lease. Otherwise, such fees and balances are recognized on a straight-line basis over the remaining obligation period with the termination payments being recorded as a component of rent receivable-deferred on the Consolidated Balance Sheets. Gains on sales of real estate are recognized based upon the specific timing of the sale as measured against various criteria related to the terms of the transactions and any continuing involvement associated with the properties. If the sales criteria are not met, the gain is deferred and the finance, installment or cost recovery method, as appropriate, is applied until the sales criteria are met. To the extent the Company sells a property and retains a partial ownership interest in the property, the Company recognizes gain to the extent of the third-party ownership interest.
Purchase Accounting and Acquisition of Real Estate	Purchase Accounting and Acquisition of Real Estate. The fair value of the real estate acquired, which includes the impact of fair value adjustments for assumed mortgage debt related to property acquisitions, is allocated to the acquired tangible assets, consisting of land, building and improvements and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, other value of in-place leases and value of tenant relationships, based in each case on their fair values. Acquisition costs are expensed as incurred and are included in property operating expense in the accompanying Consolidated Statement of Operations. The fair value of the tangible assets of an acquired property (which includes land, building and improvements and fixtures and equipment) is determined by valuing the property as if it were vacant. The “as-if-vacant” value is then allocated to land and building and improvements based on management's determination of relative fair values of these assets. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and other operating expenses and estimates of lost rental revenue during the expected lease-up periods based on current market demand. Management also estimates costs to execute similar leases including leasing commissions. In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market lease values are recorded based on the difference between the current in-place lease rent and management's estimate of current market rents. Below-market lease intangibles are recorded as part of deferred revenue and amortized into rental revenue over the non-cancelable periods and bargain renewal periods of the respective leases. Above-market leases are recorded as part of intangible assets and amortized as a direct charge against rental revenue over the non-cancelable portion of the respective leases. The aggregate value of other acquired intangible assets, consisting of in-place leases and tenant relationship values, is measured by the excess of (1) the purchase price paid for a property over (2) the estimated fair value of the property as if vacant, determined as set forth above. This aggregate value is allocated between in-place lease values and tenant relationship values based on management's evaluation of the specific characteristics of each tenant's lease. The value of in-place leases is amortized to expense over the remaining non-cancelable periods and any bargain renewal periods of the respective leases. The value of tenant relationships is amortized to expense over the applicable lease term plus expected renewal periods. Depreciation is determined by the straight-line method over the remaining estimated economic useful lives of the properties. The Company generally depreciates its real estate assets over periods ranging up to 40 years.
Impairment of Real Estate	Impairment of Real Estate. The Company evaluates the carrying value of all tangible and intangible real estate assets held for investment for possible impairment when an event or change in circumstance has occurred that indicates its carrying value may not be recoverable. The evaluation includes estimating and reviewing anticipated future undiscounted cash flows to be derived from the asset. If such cash flows are less than the asset's carrying value, an impairment charge is recognized to the extent by which the asset's carrying value exceeds its estimated fair value, which may be below the balance of any non-recourse financing. Estimating future cash flows and fair values is highly subjective and such estimates could differ materially from actual results.
Investment in Non-Consolidated Entities	Investments in Non-Consolidated Entities . The Company accounts for its investments in 50% or less owned entities under the equity method, unless consolidation is required. If the Company's investment in the entity is insignificant and the Company has no influence over the control of the entity then the entity is accounted for under the cost method.
Impairment of Equity Method Investments	Impairment of Equity Method Investments. The Company assesses whether there are indicators that the value of its equity method investments may be impaired. An impairment charge is recognized only if the Company determines that a decline in the value of the investment below its carrying value is other-than-temporary. The assessment of impairment is highly subjective and involves the application of significant assumptions and judgments about the Company's intent and ability to recover its investment given the nature and operations of the underlying investment, including the level of the Company's involvement therein, among other factors. To the extent an impairment is deemed to be other-than-temporary, the loss is measured as the excess of the carrying amount of the investment over the estimated fair value of the investment.
Loans Receivable	Loans Receivable. Loans held for investment are intended to be held to maturity and, accordingly, are carried at cost, net of unamortized loan origination costs and fees, loan purchase discounts, and net of an allowance for loan losses when such loan is deemed to be impaired. Loan origination costs and fees and loan purchase discounts are amortized over the term of the loan. The Company considers a loan impaired when, based upon current information and events, it is probable that it will be unable to collect all amounts due for both principal and interest according to the contractual terms of the loan agreement. Significant judgments are required in determining whether impairment has occurred. The Company performs an impairment analysis by comparing either the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's observable current market price or the fair value of the underlying collateral to the net carrying value of the loan, which may result in an allowance and corresponding loan loss charge. Interest income is recorded on a cash basis for impaired loans.
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 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 provide 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.
Properties Held For Sale	Properties Held For Sale. Assets and liabilities of properties that meet various held for sale criteria, including whether it is probable that a sale will occur within 12 months, are presented separately in the Consolidated Balance Sheets. Commencing January 1, 2015, the operating results of these properties are reflected as discontinued operations in the Consolidated Statements of Operations only if the sale of these assets represents a strategic shift in operations, if not, the operating results are included in continuing operations. Properties classified as held for sale are carried at the lower of net carrying value or estimated fair value less costs to sell and depreciation and amortization are no longer recognized. Properties that do not meet the held for sale criteria are accounted for as operating properties.
Deferred Expenses	Deferred Expenses. Deferred expenses consist primarily of revolving line of credit debt and leasing costs. Debt costs are amortized using the straight-line method, which approximates the interest method, over the terms of the debt instruments and leasing costs are amortized over the term of the related lease.
Derivative Financial Instruments	Derivative Financial Instruments . The Company accounts for its interest rate swap agreements in accordance with FASB ASC Topic 815, Derivatives and Hedging ("Topic 815"). In accordance with Topic 815, these agreements are carried on the balance sheet at their respective fair values, as an asset if fair value is positive, or as a liability if fair value is negative. If the interest rate swap is designated as a cash flow hedge, the effective portion of the interest rate swap's change in fair value is reported as a component of other comprehensive income (loss); the ineffective portion, if any, is recognized in earnings as an increase or decrease to interest expense. Upon entering into hedging transactions, the Company documents the relationship between the interest rate swap agreement and the hedged item. The Company also documents its risk-management policies, including objectives and strategies, as they relate to its hedging activities. The Company assesses, both at inception of a hedge and on an ongoing basis, whether or not the hedge is highly effective. The Company will discontinue hedge accounting on a prospective basis with changes in the estimated fair value reflected in earnings when (1) it is determined that the derivative is no longer effective in offsetting cash flows of a hedged item (including forecasted transactions), (2) it is no longer probable that the forecasted transaction will occur or (3) it is determined that designating the derivative as an interest rate swap is no longer appropriate. The Company does and may continue to utilize interest rate swap and cap agreements to manage interest rate risk, but does not anticipate entering into derivative transactions for speculative trading purposes.
Stock Compensation	Stock Compensation. The Company maintains an equity participation plan. Non-vested share grants generally vest either based upon (1) time, (2) performance and/or (3) market conditions. Options granted under the plan in 2010 vested over a five -year period and expire ten years from the date of grant. Options granted under the plan in 2008 vested upon attainment of certain market performance measures and expire ten years from the date of grant. All share-based payments to employees, including grants of employee stock options, are recognized in the Consolidated Statements of Operations based on their fair values.
Tax Status	Tax Status. The Company has made an election to qualify, and believes it is operating so as to qualify, as a REIT for federal income tax purposes. Accordingly, the Company generally 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 Sections 856 through 860 of the Code. The Company is permitted to participate in certain activities from which it was previously precluded 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 under the Code. As such, the Company is subject to federal and state income taxes on the income from these activities. Income taxes, primarily related to the Company's taxable REIT subsidiaries, are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled.
Cash and Cash Equivalents	Cash and Cash Equivalents. The Company considers all highly liquid instruments with maturities of three months or less from the date of purchase to be cash equivalents.
Restricted Cash	Restricted Cash. Restricted cash is comprised primarily of cash balances held in escrow with lenders.
Environmental Matters	Environmental Matters. Under various federal, state and local environmental laws, statutes, ordinances, rules and regulations, an owner of real property may be liable for the costs of removal or remediation of certain hazardous or toxic substances at, on, in or under such property as well as certain other potential costs relating to hazardous or toxic substances. These liabilities may include government fines, penalties and damages for injuries to persons and adjacent property. Such laws often impose liability without regard to whether the owner knew of, or was responsible for, the presence or disposal of such substances. Although most of the tenants of properties in which the Company has an interest are primarily responsible for any environmental damage and claims related to the leased premises, in the event of the bankruptcy or inability of the tenant of such premises to satisfy any obligations with respect to such environmental liability, or if the tenant is not responsible, the Company's property owner subsidiary may be required to satisfy any such obligations, should they exist. In addition, the property owner subsidiary, as the owner of such a property, may be held directly liable for any such damages or claims irrespective of the provisions of any lease.
Segment Reporting	Segment Reporting. The Company operates generally in one industry segment, single-tenant real estate assets.
Reclassification	Reclassifications . Certain amounts included in prior years' financial statements have been reclassified to conform to the current year's presentation.
Recently Issued Accounting Guidance	Recently Issued Accounting Guidance . In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the guidance for revenue recognition to eliminate the industry-specific revenue recognition guidance and replace it with a principle based approach for determining revenue recognition. Leases are specifically excluded from this ASU and will be governed by the applicable lease codifications; however, this update may have implications in certain variable payment terms included in lease agreements and in sale and leaseback transactions. The effective date of the new guidance was updated by ASU 2015-14 and is effective for reporting periods beginning after December 15, 2017. The Company will adopt ASU 2014-09 effective January 1, 2018 and anticipates using the modified retrospective with cumulative-effective transition method. The Company is identifying applicable revenue streams and continues to evaluate the impact of the adoption of the new guidance on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize a right of use asset and related lease liability for those leases classified as operating leases at the commencement date that have lease terms of more than 12 months. The accounting applied to lessors under this new guidance is largely unchanged from prior guidance. Lessors in most cases will continue to record operating leases as operating leases and recognize lease income from those leases generally on a straight-line basis over the lease term. The ASU is expected to result in the recognition of a right-to-use asset and related liability to account for our future obligations under our ground lease arrangements for which the Company is the lessee. As of December 31, 2016 , the remaining contractual payments under the Company's ground lease agreements aggregated $53,863 . Additionally, the new ASU will require that the Company capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. ASU 2016-02 will be effective for fiscal years beginning after December 15, 2018, and interim periods within those years, and requires a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements; with early adoption permitted. The Company continues to evaluate the impact of the adoption of the new guidance on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation-Improvements to Employee Share-Based Payment Accounting (Topic 718), which involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period; with early adoption permitted. The Company does not believe this guidance will have a material impact on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Statements, which requires more timely recognition of credit losses associated with financial assets. The ASU is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years; however, early adoption is permitted for fiscal years beginning after December 15, 2018. The Company is currently evaluating the impact of the adoption of the new guidance on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those years; with early adoption permitted. The Company does not believe this guidance will have a material impact on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which clarifies guidance on the classification and presentation of changes in restricted cash. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted, and will be applied retrospectively to all periods presented. Upon adoption, restricted cash balances will be included along with cash and cash equivalents as of the end of the period and beginning of period, respectively, in the Company's consolidated statement of cash flows for all periods presented. Upon adoption, separate line items showing changes in restricted cash balances will be eliminated from the Company's consolidated statement of cash flows. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which clarifies the definition of a business when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The Company expects that acquisitions of real estate or in-substance real estate will not meet the revised definition of a business and thus will be treated as asset acquisitions. In February 2017, the FASB issued ASU 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Topic 610-20), which requires that all entities account for the derecognition of a business in accordance with ASC 810, including instances in which the business is considered in-substance real estate. The ASU is effective for annual periods, and interim periods therein, beginning after December 15, 2017. Early application is permitted. The Company is currently evaluating the impact of the adoption of the new guidance on its consolidated financial statements.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation. The Partnership's 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 Partnership and its consolidated subsidiaries. The Partnership consolidates its wholly-owned subsidiaries, partnerships and joint ventures which it controls (i) through voting rights or similar rights or (ii) by means other than voting rights if the Partnership is the primary beneficiary of a variable interest entity (“VIE”). Entities which the Partnership does not control and entities which are VIEs in which the Partnership is not the primary beneficiary are accounted for under appropriate GAAP.
Earnings Per Share	Earnings Per Unit . Net income (loss) per unit is computed by dividing net income (loss) by the weighted-average number of units outstanding during the period. There are no potential dilutive securities.
Partners' Capital, Unit Redemptions	Unit Redemptions . The Partnership's limited partner units that are issued and outstanding, other than those held by Lexington, are currently redeemable at certain times, only at the option of the holders, for Lexington shares of beneficial interests, par value $0.0001 per share classified as common stock (“common shares”), on a one to approximately 1.13 basis, subject to future adjustments. These units are not otherwise mandatorily redeemable by the Partnership.
Allocation of Overhead Expenses	Allocation of Overhead Expenses . The Partnership does not pay a fee to the General Partner for the day-to-day management of the Partnership. Certain expenses incurred by the General Partner and its affiliates, including Lexington, such as corporate-level interest, amortization of deferred loan costs, payroll and general and administrative expenses are allocated to the Partnership and reimbursed to the General Partner in accordance with the Partnership's partnership agreement. The allocation is based upon gross rental revenues.
Distributions And Allocations Of Income And Loss	Distributions; Allocations of Income and Loss . As provided in the Partnership's partnership agreement, distributions and income and loss for financial reporting purposes are allocated to the partners based on their ownership of units. Special allocation rules included in the partnership agreement affect the allocation of taxable income and loss.
Use of Estimates	Use of Estimates. The Partnership 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 consolidated financial statements in conformity with GAAP. These estimates and assumptions are based on management's best estimates and judgment. The Partnership evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the economic environment. The economic environment has increased the degree of uncertainty inherent in these estimates and assumptions. The Partnership adjusts such estimates when facts and circumstances dictate. The most significant estimates made include the recoverability of accounts receivable, 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 and the useful lives of long-lived assets. Actual results could differ materially from those estimates.
Fair Value Measurements	Fair Value Measurements. The Partnership follows the guidance in the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures ("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 Partnership 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 counter-party credit risk.
Revenue Recognition	Revenue Recognition. The Partnership recognizes lease revenue on a straight-line basis over the term of the lease unless another systematic and rational basis is more representative of the time pattern in which the use benefit is derived from the leased property. Revenue is recognized on a contractual basis for leases with escalations tied to a consumer price index with no floor. Renewal options in leases with rental terms that are lower than those in the primary term are excluded from the calculation of straight-line rent if the renewals are not reasonably assured. If the Partnership funds tenant improvements and the improvements are deemed to be owned by the Partnership, revenue recognition will commence when the improvements are substantially completed and possession or control of the space is turned over to the tenant. If the Partnership determines that the tenant allowances are lease incentives, the Partnership commences revenue recognition when possession or control of the space is turned over to the tenant for tenant work to begin. The lease incentive is recorded as a deferred expense and amortized as a reduction of revenue on a straight-line basis over the respective lease term. The Partnership recognizes lease termination fees as rental revenue in the period received and writes off unamortized lease-related intangible and other lease-related account balances, provided there are no further Partnership obligations under the lease. Otherwise, such fees and balances are recognized on a straight-line basis over the remaining obligation period with the termination payments being recorded as a component of rent receivable-deferred on the Consolidated Balance Sheets. Gains on sales of real estate are recognized based upon the specific timing of the sale as measured against various criteria related to the terms of the transactions and any continuing involvement associated with the properties. If the sales criteria are not met, the gain is deferred and the finance, installment or cost recovery method, as appropriate, is applied until the sales criteria are met. To the extent the Partnership sells a property and retains a partial ownership interest in the property, the Partnership recognizes gain to the extent of the third-party ownership interest.
Purchase Accounting and Acquisition of Real Estate	Purchase Accounting and Acquisition of Real Estate. The fair value of the real estate acquired, which includes the impact of fair value adjustments for assumed mortgage debt related to property acquisitions, is allocated to the acquired tangible assets, consisting of land, building and improvements and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, other value of in-place leases and value of tenant relationships, based in each case on their fair values. Acquisition costs are expensed as incurred and are included in property operating expense in the accompanying Consolidated Statement of Operations. The fair value of the tangible assets of an acquired property (which includes land, building and improvements and fixtures and equipment) is determined by valuing the property as if it were vacant. The “as-if-vacant” value is then allocated to land and building and improvements based on management's determination of relative fair values of these assets. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and other operating expenses and estimates of lost rental revenue during the expected lease-up periods based on current market demand. The Partnership also estimates costs to execute similar leases including leasing commissions. In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market lease values are recorded based on the difference between the current in-place lease rent and the Partnership's estimate of current market rents. Below-market lease intangibles are recorded as part of deferred revenue and amortized into rental revenue over the non-cancelable periods and bargain renewal periods of the respective leases. Above-market leases are recorded as part of intangible assets and amortized as a direct charge against rental revenue over the non-cancelable portion of the respective leases. The aggregate value of other acquired intangible assets, consisting of in-place leases and tenant relationship values, is measured by the excess of (1) the purchase price paid for a property over (2) the estimated fair value of the property as if vacant, determined as set forth above. This aggregate value is allocated between in-place lease values and tenant relationship values based on management's evaluation of the specific characteristics of each tenant's lease. The value of in-place leases is amortized to expense over the remaining non-cancelable periods and any bargain renewal periods of the respective leases. The value of tenant relationships are amortized to expense over the applicable lease term plus expected renewal periods. Depreciation is determined by the straight-line method over the remaining estimated economic useful lives of the properties. The Partnership generally depreciates its real estate assets over periods ranging up to 40 years.
Impairment of Real Estate	Impairment of Real Estate. The Partnership evaluates the carrying value of all tangible and intangible real estate assets held for investment for possible impairment when an event or change in circumstance has occurred that indicates its carrying value may not be recoverable. The evaluation includes estimating and reviewing anticipated future undiscounted cash flows to be derived from the asset. If such cash flows are less than the asset's carrying value, an impairment charge is recognized to the extent by which the asset's carrying value exceeds the estimated fair value, which may be below the balance of any non-recourse financing. Estimating future cash flows and fair values is highly subjective and such estimates could differ materially from actual results.
Investment in Non-Consolidated Entities	Investments in Non-Consolidated Entities . The Partnership accounts for its investments in 50% or less owned entities under the equity method, unless consolidation is required. If the Partnership's investment in the entity is insignificant and the Partnership has no influence over the control of the entity then the entity is accounted for under the cost method.
Impairment of Equity Method Investments	Impairment of Equity Method Investments. The Partnership assesses whether there are indicators that the value of its equity method investments may be impaired. An impairment charge is recognized only if the Partnership determines that a decline in the value of the investment below its carrying value is other-than-temporary. The assessment of impairment is highly subjective and involves the application of significant assumptions and judgments about the Partnership's intent and ability to recover its investment given the nature and operations of the underlying investment, among other factors. To the extent an impairment is deemed to be other-than-temporary, the loss is measured as the excess of the carrying amount of the investment over the estimated fair value of the investment.
Acquisition, Development and Construction Arrangements	Acquisition, Development and Construction Arrangements. The Partnership evaluates loans receivable where the Partnership participates in residual profits through loan provisions or other contracts to ascertain whether the Partnership has the same risks and rewards as an owner or a joint venture partner. Where the Partnership concludes that such arrangements are more appropriately treated as an investment in real estate, the Partnership reflects such loan receivable as an equity investment in real estate under construction in the Consolidated Balance Sheets. In these cases, no interest income is recorded on the loan receivable and the Partnership records capitalized interest during the construction period. In arrangements where the Partnership engages a developer to construct a property or provide funds to a tenant to develop a property, the Partnership will capitalize the funds provided to the developer/tenant and internal costs of interest and real estate taxes, if applicable, during the construction period.
Properties Held For Sale	Properties Held For Sale. Assets and liabilities of properties that meet various held for sale criteria, including whether it is probable that a sale will occur within 12 months, are presented separately in the Consolidated Balance Sheets. Commencing January 1, 2015, the operating results of these properties are reflected as discontinued operations in the Consolidated Statements of Operations only if the sale of these assets represents a strategic shift in operations, if not, the operating results are included in continuing operations. Properties classified as held for sale are carried at the lower of net carrying value or estimated fair value less costs to sell and depreciation and amortization are no longer recognized. Properties that do not meet the held for sale criteria are accounted for as operating properties.
Deferred Expenses	Deferred Expenses. Deferred expenses consist primarily of leasing costs, which are amortized over the term of the related lease.
Tax Status	Income Taxes. Because the Partnership is a limited partnership, taxable income or loss of the Partnership is reported in the income tax returns of its partners. Accordingly, no provision for income taxes is made in the Consolidated Financial Statements of the Partnership. However, the Partnership is required to pay certain state and local entity level taxes which are expensed as incurred.
Cash and Cash Equivalents	Cash and Cash Equivalents. The Partnership considers all highly liquid instruments with maturities of three months or less from the date of purchase to be cash equivalents.
Restricted Cash	Restricted Cash. Restricted cash is comprised primarily of cash balances held in escrow with lenders.
Co-borrower Debt	Co-borrower Debt. In February 2013, the FASB issued Accounting Standards Update (“ASU”) 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date (“ASU 2013-04”), requiring recognition of such obligations as the sum of (a) the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and (b) any additional amount the reporting entity expects to pay on behalf of its co-obligors.
Environmental Matters	Environmental Matters. Under various federal, state and local environmental laws, statutes, ordinances, rules and regulations, an owner of real property may be liable for the costs of removal or remediation of certain hazardous or toxic substances at, on, in or under such property as well as certain other potential costs relating to hazardous or toxic substances. These liabilities may include government fines, penalties and damages for injuries to persons and adjacent property. Such laws often impose liability without regard to whether the owner knew of, or was responsible for, the presence or disposal of such substances. Although most of the tenants of properties in which the Partnership has an interest are primarily responsible for any environmental damage and claims related to the leased premises, in the event of the bankruptcy or inability of the tenant of such premises to satisfy any obligations with respect to such environmental liability, or if the tenant is not responsible, the Partnership's property owner subsidiary may be required to satisfy any such obligations, should they exist. In addition, the property owner subsidiary, as the owner of such a property, may be held directly liable for any such damages or claims irrespective of the provisions of any lease. As of December 31, 2016 , the Partnership was not aware of any environmental matter relating to any of its investments that would have a material impact on the consolidated financial statements.
Segment Reporting	Segment Reporting. The Partnership operates generally in one industry segment, single-tenant real estate assets.
Reclassification	Reclassifications . Certain amounts included in prior years' financial statements have been reclassified to conform to the current year's presentation.
Recently Issued Accounting Guidance	Recently Issued Accounting Guidance. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the guidance for revenue recognition to eliminate the industry-specific revenue recognition guidance and replace it with a principle based approach for determining revenue recognition. The effective date of the new guidance was updated by ASU 2015-14 and is effective for reporting periods beginning after December 15, 2017. The Partnership will adopt ASU 2014-09 effective January 1, 2018 and anticipates using the modified retrospective with cumulative-effective transition method. The Partnership is identifying applicable revenue streams and continues to evaluate the impact of the adoption of the new guidance on its consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810) - Amendments to the Consolidation Analysis,” which provides guidance on the consolidation evaluation for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. In accordance with the guidance, all legal entities are subject to reevaluation under the revised consolidation model. The guidance was effective in the first quarter of fiscal 2016. The adoption of this guidance did not have an impact on the Partnership. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize a right of use asset and related lease liability for those leases classified as operating leases at the commencement date and have lease terms of more than 12 months. The accounting applied to lessors under this new guidance is largely unchanged from prior guidance. Lessors in most cases will continue to record operating leases as operating leases and recognize lease income from these leases generally on a straight-line basis over the lease term. The ASU is expected to result in the recognition of a right-to-use asset and related liability to account for our future obligations under our ground lease arrangements for which the Partnership is the lessee. As of December 31, 2016 , the remaining contractual payments under the Partnership's ground lease agreements aggregated $3,810 . Additionally, the new ASU will require that the Partnership capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, and requires a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early adoption is permitted. The Partnership continues to evaluate the impact of the adoption of the new guidance on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those years; however early adoption is permitted. The Partnership does not believe this guidance will have a material impact on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which clarifies guidance on the classification and presentation of changes in restricted cash. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted, and will be applied retrospectively to all periods presented. Upon adoption, restricted cash balances will be included along with cash and cash equivalents as of the end of the period and beginning of period, respectively, in the Partnership's consolidated statement of cash flows for all periods presented. Upon adoption, separate line items showing changes in restricted cash balances will be eliminated from the Partnership's consolidated statement of cash flows. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which clarifies the definition of a business when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The Partnership expects that acquisitions of real estate or in-substance real estate will not meet the revised definition of a business and thus will be treated as asset acquisitions. In February 2017, the FASB issued ASU 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Topic 610-20), which requires that all entities account for the derecognition of a business in accordance with ASC 810, including instances in which the business is considered in-substance real estate. The ASU is effective for annual periods, and interim periods therein, beginning after December 15, 2017. Early application is permitted. The Partnership is currently evaluating the impact of the adoption of the new guidance on its consolidated financial statements.
