Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Partnership and Financial Statement Presentation	The Partnership and Financial Statement Presentation
	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 serves as an operating partnership subsidiary for Lexington. 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. As of March 31, 2015, Lexington, through Lex LP-1 Trust, a wholly-owned subsidiary, and the General Partner, owned approximately 95.0% of the outstanding units of the Partnership.
	The Partnership owns a diversified portfolio of equity and debt investments in single-tenant properties and land. As of March 31, 2015, the Partnership had equity ownership interests in 42 consolidated properties located in 25 states. A majority of the real properties in which the Partnership had an interest and all land interests 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.
	The assets and credit of a subsidiary of the Partnership are not available to satisfy the debt and the other obligations of any other person, including any other subsidiary of the Partnership or any other affiliate.
	Basis of Presentation and Consolidation. The Partnership's unaudited condensed consolidated financial statements are prepared on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles (“GAAP”). The financial statements reflect the accounts of the 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.
	The financial statements contained in this Quarterly Report on Form 10-Q for the three months ended March 31, 2015 (this “Quarterly Report”) have been prepared by the Partnership in accordance with GAAP for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all information and footnotes required by GAAP for complete financial statements. However, in the opinion of management, the interim financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results of the periods presented. The results of operations for the three months ended March 31, 2015 and 2014, are not necessarily indicative of the results that may be expected for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the Partnership's audited consolidated financial statements and notes thereto included in the Partnership's Form 10-K for the year ended December 31, 2014 filed with the SEC on February 26, 2015 (“Annual Report”).
	Earnings Per Unit. Net income per unit is computed by dividing net income 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 shares of beneficial interests of Lexington, 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 mandatorily redeemable by the Partnership. As of March 31, 2015, Lexington's common shares had a closing price of $9.83 per share. The estimated fair value of these units was $37,875, 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 $14,358 ($0.20 per weighted-average unit) and $13,543 ($0.20 per weighted-average unit) to its partners during the three months ended March 31, 2015 and 2014, respectively. Certain units owned indirectly by Lexington are entitled to aggregate annual 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 unaudited condensed 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 current economic environment. The current 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 counterparty credit risk.
	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 unaudited condensed 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.
	Reclassifications. Certain amounts included in prior years' financial statements have been reclassified to conform to the current year presentation, including certain statements of operations captions, including activities for properties sold, which are presented in discontinued operations.
	Co-borrower Debt. In February 2013, the FASB issued Accounting Standards Update 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. The Partnership early adopted this new guidance in 2013 retrospectively (see note 6).
	Recently Issued Accounting Guidance. In April 2014, the FASB issued Accounting Standards Update No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which changes the criteria for reporting discontinued operations and improves financial statement disclosures. Under this guidance, only disposals representing a strategic shift in operations that have a major effect on an organization's operations and financial results should be presented as discontinued operations. The Partnership adopted this guidance effective January 1, 2015. The implementation of this guidance did not have a material impact on the Partnership's financial position, results of operations or cash flows.
	In May 2014, the FASB issued Accounting Standards Update No. 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 new guidance is effective for reporting periods beginning after December 15, 2016. The Partnership is currently evaluating the impact of the adoption of the new guidance on its unaudited condensed consolidated financial statements.
	In February 2015, the FASB issued Accounting Standards Update 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 is effective in the first quarter of 2016 and early adoption is allowed. The Partnership is currently evaluating the impact of the adoption of this new guidance on its unaudited condensed consolidated financial statements.
	In April 2015, the FASB issued Accounting Standards Update 2015-03, “Simplifying the Presentation of Debt Issuance Costs”, which requires that debt issuance costs be presented on the balance sheet as a direct deduction from the carrying amount of the related debt liability. The guidance is effective in the first quarter of 2016 and requires retrospective application. The Partnership is currently evaluating the impact of the adoption of this new guidance on its unaudited condensed consolidated financial statements.

	As of March 31, 2015 and December 31, 2014, the Partnership's loans receivable were comprised of mortgage loans on real estate.
	The following is a summary of the Partnership's loans receivable as of March 31, 2015 and December 31, 2014:
			Loan carrying-value(1)

	-1	Loan carrying value includes accrued interest and is net of origination costs and loan losses, if any.
	-2	Borrowers are in default and the Partnership commenced foreclosure proceedings. The tenant at the office property constituting the collateral terminated its lease. The Partnership recognized a loan loss of $13,939 during 2013. During the three months ended March 31, 2015 and 2014, the Partnership recognized $0 and $425 of interest income relating to the impaired loan, respectively, and the loan had an average recorded investment value of $12,510 and $12,561, respectively. At March 31, 2015, the impaired loan receivable had a contractual unpaid balance of $29,455.
	-3	The Partnership recorded a $2,500 loan loss in the fourth quarter of 2014 as the Partnership determined it was probable that it would not collect the amount owed at maturity. During the three months ended March 31, 2015, the Partnership recognized $14 of interest income relating to the impaired loan and the loan had an average recorded investment of $3,303. At March 31, 2015, the impaired loan receivable had a contractual unpaid balance of $6,083. See note 11.
	The Partnership had two types of financing receivables: loans receivable and a capitalized financing lease. The Partnership determined that its financing receivables operated within one portfolio segment as they are within the same industry and use the same impairment methodology. The Partnership's loans receivable are secured by commercial real estate assets and the capitalized financing lease, for a commercial property located in Greenville, South Carolina, was sold in December 2014. In addition, the Partnership assesses all financing receivables for impairment, when warranted, based on an individual analysis of each receivable.
	The Partnership'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 Partnership uses credit quality indicators to monitor financing receivables such as quality of collateral, the underlying tenant's credit rating and collection experience.

	Liabilities
	Debt (Level 3)		$	504,490		$	509,445		$	465,318		$	470,281
	The Partnership estimates the fair values of its loans receivable 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 Partnership's debt is estimated by using a discounted cash flow analysis, based upon estimates of market interest rates.
	Fair values cannot be determined with precision, may not be substantiated by comparison to quoted prices in active markets and may not be realized upon sale. Additionally, there are inherent uncertainties in any fair value measurement technique, and changes in the underlying assumptions used, including discount rates, liquidity risks and estimates of future cash flows, could significantly affect the fair value measurement amounts.
	Cash Equivalents, Restricted Cash, Accounts Receivable and Accounts Payable. The Partnership 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.

Mortgages and Notes Payable and Co-Borrower Debt	Mortgages and Notes Payable and Co-Borrower Debt
	The Partnership had outstanding mortgages and notes payable of $328,514 and $328,351 as of March 31, 2015 and December 31, 2014, respectively. Interest rates, including imputed rates, ranged from 4.1% to 6.5% at March 31, 2015, 4.7% to 6.5% at December 31, 2014 and the mortgages and notes payable mature between 2016 and 2027. The weighted-average interest rate at March 31, 2015 and December 31, 2014 was approximately 4.9% and 5.0%, respectively.
	Lexington, and the Partnership as co-borrower, have a $400,000 unsecured revolving credit facility with KeyBank National Association (“KeyBank”), as agent. The unsecured revolving credit facility matures in February 2017 but can be extended until February 2018 at Lexington’s option. The unsecured revolving credit facility bears interest at LIBOR plus 0.95% to 1.725% (1.15% as of March 31, 2015). At March 31, 2015, the unsecured revolving credit facility had $93,000 outstanding, outstanding letters of credit of $12,144 and availability of $294,856, subject to covenant compliance.
	Lexington, and the Partnership as co-borrower, have a five-year $250,000 unsecured term loan facility from KeyBank, as agent. The unsecured term loan matures in February 2018, may be prepaid without penalty and requires regular payments of interest only at interest rates ranging from LIBOR plus 1.10% to 2.10% (1.35% as of March 31, 2015). As of March 31, 2015, interest rate swap agreements were entered into to fix the LIBOR component at a weighted-average rate of 1.09% through February 2018 on the $250,000 of outstanding LIBOR-based borrowings.
	Lexington, and the Partnership as co-borrower, have a $255,000 unsecured term loan from Wells Fargo Bank, National Association (“Wells Fargo”), as agent. The term loan matures in January 2019. The term loan requires regular payments of interest only at interest rates ranging from LIBOR plus 1.50% to 2.25% (1.75% as of March 31, 2015). Lexington may prepay any outstanding borrowings under the term loan facility at a premium through January 12, 2016 and at par thereafter. Interest rate swap agreements were entered into to fix the LIBOR component at a weighted-average rate of 1.42% through January 2019 on the $255,000 of outstanding LIBOR-based borrowings.
	Lexington was in compliance with all applicable financial covenants contained in its corporate level debt agreements at March 31, 2015.
	In accordance with the guidance of ASU 2013-04, the Partnership, as it is a co-borrower with Lexington, recognizes a proportion of the outstanding amounts of the above mentioned term loans and revolving credit facility as co-borrower debt in the accompanying unaudited condensed consolidated balances sheets. In accordance with the Partnership’s partnership agreement, the Partnership is allocated a portion of these debts based on gross rental revenues, which represents its agreed to obligation. The Partnership's allocated co-borrower debt was $175,976 and $136,967 as of March 31, 2015 and December 31, 2014, respectively. Changes in co-borrower debt are recognized in partners’ capital in the accompanying unaudited condensed consolidated statements of changes in partners’ capital.
	Mortgages payable and secured loans are generally collateralized by real estate and the related leases. Certain mortgages payable have yield maintenance or defeasance requirements relating to any prepayments. In addition, certain mortgages are cross-collateralized and cross-defaulted.

Risks and Uncertainties [Abstract]
Concentration of Risk	Concentration of Risk
	Subject to the terms of the partnership agreement, the Partnership seeks to reduce its operating and leasing risks through the geographic diversification of its properties, tenant industry diversification, avoidance of dependency on a single asset and the creditworthiness of its tenants. For the three months ended March 31, 2015 and 2014, the following tenants represented greater than 10% of rental revenues from continuing operations:
		2015		2014
	LG-39 Ground Tenant LLC	14.7	%	16.1	%
	FC-Canal Ground Tenant LLC	12.6	%	13.8	%
	AL-Stone Ground Tenant LLC	11.5	%	12.6	%
	The Partnership net leases these individual land parcels to the tenants under non-cancellable 99-year leases. The improvements on these parcels are owned by the tenants under the Partnership leases and currently consist of three high-rise hotels located in New York, NY. The hotels are known as the Element New York Times Square West, the Sheraton Tribeca New York Hotel and the DoubleTree by Hilton Hotel New York City - Financial District, respectively.
	Cash and cash equivalent balances at certain institutions may exceed insurable amounts. The Partnership believes it mitigates this risk by investing in or through major financial institutions.

In addition, the Partnership had outstanding net advances owed to Lexington of $18,076 and $3,061 as of March 31, 2015 and December 31, 2014, respectively. The advances are payable on demand. Lexington earned distributions of $13,735 and $12,966 during the three months ended March 31, 2015 and 2014, respectively.
	The Partnership was allocated interest expense by Lexington, in accordance with the partnership agreement, relating to certain lending facilities of $3,015 and $2,017 for the three months ended March 31, 2015 and 2014, respectively.
	Lexington, on behalf of the General Partner, pays for certain general administrative and other costs on behalf of the Partnership from time to time. These costs are reimbursable by the Partnership. These costs were approximately $2,062 and $2,130 for the three months ended March 31, 2015 and 2014, respectively.
	A Lexington affiliate provides property management services for certain Partnership properties. The Partnership recognized property operating expenses of $289 and $271 for the three months ended March 31, 2015 and 2014, respectively, for aggregate fees and reimbursements charged by the affiliate.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies
	In addition to the commitments and contingencies disclosed elsewhere, the Partnership has the following commitments and contingencies.
	The Partnership 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. During 2014, the Partnership commenced the expansion of the Byhalia, Mississippi property for an estimated cost of $15,300. The Partnership, 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 Partnership and Lexington are parties to a funding agreement under which each party may be required to fund distributions made on account of OP units or dividends made on account of Lexington common shares. Pursuant to the funding agreement, the parties agreed that, if the Partnership does not have sufficient cash available to make a quarterly distribution to its limited partners in an amount equal to whichever is applicable of (1) a specified distribution set forth in its partnership agreement or (2) the cash dividend payable with respect to a whole or fractional Lexington common share into which the partnership's common units would be converted if they were redeemed for Lexington common shares in accordance with the partnership agreement, Lexington will fund the shortfall. Payments under the agreement will be made in the form of loans to the Partnership and will bear interest at prevailing rates as determined by Lexington in its discretion but no less than the applicable federal rate. The Partnership's right to receive these loans will expire if no OP units remain outstanding and all such loans were repaid. No amounts have been advanced under this agreement.
	In May 2014, the Partnership guaranteed $250,000 aggregate principal amount of 4.40% Senior Notes due 2024 (“2024 Senior Notes”) issued by Lexington at an issuance price of 99.883% of the principal amount and in June 2013, the Partnership guaranteed $250,000 aggregate principal amount of 4.25% Senior Notes due 2023 (“ 2023 Senior Notes”) issued by Lexington at an issuance price of 99.026% of the principal amount, collectively the Senior Notes. The Senior Notes are unsecured and pay interest semi-annually in arrears. Lexington may redeem the Senior Notes at its option at any time prior to maturity in whole or in part by paying the principal amount of the notes being redeemed plus a premium.
	During 2010, the Partnership guaranteed $115,000 aggregate principal amount of 6.00% Convertible Guaranteed Notes due 2030 (“Guaranteed Notes”) issued by Lexington. The Guaranteed Notes pay interest semi-annually in arrears and mature in January 2030. The holders of the Guaranteed Notes may require Lexington to repurchase their notes in January 2017, January 2020 and January 2025 for cash equal to 100% of the notes to be repurchased, plus any accrued and unpaid interest. The Guaranteed Notes are convertible by the holders under certain circumstances for cash, Lexington common shares or a combination of cash and common shares at Lexington's election. As of March 31, 2015, $15,628 original principal amount of Guaranteed Notes were outstanding.
	From time to time, the Partnership is directly or indirectly involved in legal proceedings arising in the ordinary course of the Partnership's business. The Partnership 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 Partnership's business, financial condition and results of operations.

The_Partnership_and_Financial_1

The Partnership and Financial Statement Presentation (Policies)	3 Months Ended
	Mar. 31, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation. The Partnership's unaudited condensed consolidated financial statements are prepared on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles (“GAAP”). The financial statements reflect the accounts of the 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.
	The financial statements contained in this Quarterly Report on Form 10-Q for the three months ended March 31, 2015 (this “Quarterly Report”) have been prepared by the Partnership in accordance with GAAP for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all information and footnotes required by GAAP for complete financial statements. However, in the opinion of management, the interim financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results of the periods presented. The results of operations for the three months ended March 31, 2015 and 2014, are not necessarily indicative of the results that may be expected for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the Partnership's audited consolidated financial statements and notes thereto included in the Partnership's Form 10-K for the year ended December 31, 2014 filed with the SEC on February 26, 2015 (“Annual Report”).
Earnings Per Unit	Earnings Per Unit. Net income per unit is computed by dividing net income by the weighted-average number of units outstanding during the period. There are no potential dilutive securities.
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 shares of beneficial interests of Lexington, 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 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; 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 unaudited condensed 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 current economic environment. The current 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 counterparty credit risk.
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 unaudited condensed 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.
Reclassifications	Reclassifications. Certain amounts included in prior years' financial statements have been reclassified to conform to the current year presentation, including certain statements of operations captions, including activities for properties sold, which are presented in discontinued operations.
Co-borrower Debt	Co-borrower Debt. In February 2013, the FASB issued Accounting Standards Update 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. The Partnership early adopted this new guidance in 2013 retrospectively (see note 6).
Recently Issued Accounting Guidance	Recently Issued Accounting Guidance. In April 2014, the FASB issued Accounting Standards Update No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which changes the criteria for reporting discontinued operations and improves financial statement disclosures. Under this guidance, only disposals representing a strategic shift in operations that have a major effect on an organization's operations and financial results should be presented as discontinued operations. The Partnership adopted this guidance effective January 1, 2015. The implementation of this guidance did not have a material impact on the Partnership's financial position, results of operations or cash flows.
	In May 2014, the FASB issued Accounting Standards Update No. 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 new guidance is effective for reporting periods beginning after December 15, 2016. The Partnership is currently evaluating the impact of the adoption of the new guidance on its unaudited condensed consolidated financial statements.
	In February 2015, the FASB issued Accounting Standards Update 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 is effective in the first quarter of 2016 and early adoption is allowed. The Partnership is currently evaluating the impact of the adoption of this new guidance on its unaudited condensed consolidated financial statements.
	In April 2015, the FASB issued Accounting Standards Update 2015-03, “Simplifying the Presentation of Debt Issuance Costs”, which requires that debt issuance costs be presented on the balance sheet as a direct deduction from the carrying amount of the related debt liability. The guidance is effective in the first quarter of 2016 and requires retrospective application. The Partnership is currently evaluating the impact of the adoption of this new guidance on its unaudited condensed consolidated financial statements.
