Subsequent Events [Abstract]
Subsequent Events	Subsequent Events NLOP Spin-Off On November 1, 2023, we completed the Spin-Off of 59 office properties into NLOP, as described in further detail in Note 1. The Spin-Off was accomplished via a pro rata dividend of one NLOP common share for every 15 shares of WPC common stock outstanding. Following the closing of the Spin-Off, NLOP operates as a separate publicly-traded REIT, for which we serve as advisor pursuant to the NLOP Advisory Agreements executed in connection with the Spin-Off, as described below in further detail. Pursuant to the NLOP Advisory Agreements, which we entered into on November 1, 2023, we provide NLOP with strategic management services, including asset management, property disposition support, and various related services. NLOP will pay us an asset management fee of approximately $7.5 million annually, which will be proportionately reduced following the disposition of a portfolio property. In addition, NLOP will reimburse us a base administrative amount of approximately $4.0 million annually, for certain administrative services, including day-to-day management services, investor relations, accounting, tax, legal, and other administrative matters. On October 31, 2023, we entered into a Separation and Distribution Agreement, which set forth the various individual transactions to be consummated that comprised the Separation and the Distribution, including the assets transferred to and liabilities assumed by NLOP. On October 31, 2023, we also entered into a Tax Matters Agreement, which governs the respective rights, responsibilities, and obligations of us and NLOP after the Distribution, with respect to tax liabilities and benefits, the preparation and filing of tax returns, the control of audits and other tax proceedings, tax covenants, tax indemnification, cooperation, and information sharing. In September 2023, NLOP entered into a new $455 million debt facility (Note 11), which was executed by NLOP and funded upon the closing of the Spin-Off on November 1, 2023. Approximately $350 million of this amount (net of transaction expenses) was retained by us in connection with the Spin-Off. In connection with the Spin-Off, we have incurred approximately $61.6 million in total costs, comprised of (i) $10.0 million of advisory fees, which is included in Merger and other expenses on our consolidated statements of income ($4.9 million of such fees were recognized during 2022 and $5.1 million were recognized during the nine months ended September 30, 2023); and (ii) $51.6 million of additional Spin-Off related costs, which were reimbursed to us by NLOP in connection with the Spin-Off.
