The Company [Abstract]
The Company	The Company Lexington Realty Trust (the “Company”) is a self-managed and self-administered Maryland statutory real estate investment trust (“REIT”) that acquires, owns, manages and provides financing for a geographically diversified portfolio of predominately single-tenant office, industrial and retail properties, including build-to-suit transactions. The Company also provides investment advisory and asset management services to investors in the single-tenant area. As of September 30, 2011, the Company had equity interests in approximately 185 consolidated properties in 39 states. The real properties in which the Company has an equity interest are generally subject to net leases or similar leases where the tenant pays all or substantially all of the cost and/or cost increases for real estate taxes, insurance, utilities and ordinary maintenance of the property. However, certain leases provide that the Company's property owner subsidiary is responsible for certain or all operating expenses. The Company believes it has qualified as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). Accordingly, the Company will not be subject to federal income tax, provided that distributions to its shareholders equal at least the amount of its REIT taxable income as defined under the Code. The Company is permitted to participate in certain activities in order to maintain its qualification as a REIT, so long as these activities are conducted in entities which elect to be treated as taxable REIT subsidiaries (“TRS”) under the Code. As such, the TRS will be subject to federal income taxes on the income from these activities. The Company conducts its operations either directly or indirectly through (1) property owner subsidiaries and lender subsidiaries, (2) operating partnerships in which the Company is the sole unit holder of the general partner and the sole unit holder of the limited partner that holds a majority of the limited partner interests (“OP units”), (3) through a wholly-owned TRS or (4) through investments in joint ventures. Property owner subsidiaries are landlords under leases and/or borrowers under loan agreements and lender subsidiaries are lenders under loan agreements, but in all cases are separate and distinct legal entities. The unaudited condensed consolidated financial statements reflect all adjustments, which are, in the opinion of management, necessary to present fairly the financial condition and results of operations for the interim periods. For a more complete understanding of the Company's operations and financial position, reference is made to the consolidated financial statements (including the notes thereto) previously filed with the Securities and Exchange Commission ("SEC") on February 28, 2011 as part of the Company's Annual Report on Form 10-K for the year ended December 31, 2010 (the “Annual Report”).
