Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In addition to the commitments and contingencies disclosed elsewhere and previously disclosed, the Company has the following commitments and contingencies. The Company is obligated under certain tenant leases, 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 are repaid. No amounts have been advanced under this agreement. From time to time, the Company is directly and indirectly involved in legal proceedings arising in the ordinary course of business. Management believes, based on currently available information, and after consultation with legal counsel, that although the outcomes of those normal course proceedings are uncertain, the results of such proceedings, in the aggregate, will not have a material adverse effect on the Company's business, financial condition and results of operations, except for the following: Cummins Inc. v. Lexington Columbus (Jackson Street) L.P. and Wells Fargo Bank, N.A. (State of Indiana, County of Bartholomew, in the Bartholomew Superior Court). On October 25, 2018, Cummins Inc., the tenant in the Columbus, Indiana office building, filed a complaint for declaratory relief against Lexington Columbus (Jackson Street) L.P., the Company's property owner subsidiary, and Wells Fargo Bank, N.A., the trustee for the noteholders with a security interest in the office building. Under the subject lease, Cummins Inc.’s tenancy extends through July 31, 2024, with options to further extend for additional time periods. Despite failing to timely exercise a purchase option for the office building that was expressly due by July 15, 2018, where time was of the essence, Cummins Inc. has asked the court for a declaration that it is entitled to purchase the building at the option price and to terminate the lease effective July 31, 2019. Cummins Inc. does not dispute that it failed to comply with the requirements of the purchase option, but alleges that it is entitled to relief under several equitable theories. Lexington Columbus (Jackson Street) L.P. filed a motion to dismiss the complaint on January 8, 2019. A hearing on the motion to dismiss is scheduled for May 16, 2019. The Company believes that Indiana law supports the Company's right to retain ownership of the building and intends to vigorously defend this claim.
