Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Global Net Lease, Inc. (the "Company"), formerly known as American Realty Capital Global Trust, Inc., incorporated on July 13, 2011, is a Maryland corporation that elected and qualified to be taxed as a real estate investment trust ("REIT") for U.S. federal income tax purposes beginning with the taxable year ended December 31, 2013. The Company operated as a non-traded REIT through June 1, 2015. On June 2, 2015 (the "Listing Date"), the Company listed its Common Stock (the "Listing") on the New York Stock Exchange ("NYSE") under the symbol "GNL". The Company was formed to primarily acquire a diversified portfolio of commercial properties, with an emphasis on sale-leaseback transactions involving single tenant net-leased commercial properties. As of September 30, 2016, the Company owned 326 properties consisting of 18.6 million rentable square feet, which were 100% leased, with a weighted average remaining lease term of 10.5 years. Based on original purchase price, 60.2% of the Company's properties are located in the U.S. and the Commonwealth of Puerto Rico and 39.8% are located in Europe. The Company may also originate or acquire first mortgage loans secured by real estate. As of September 30, 2016, the Company has not invested in any mezzanine loans, preferred equity or securitized loans. On June 30, 2014, the Company completed its initial public offering ("IPO") after selling 172.3 million shares of common stock, $0.01 par value per share ("Common Stock"), at a price of $10.00 per share, subject to certain volume and other discounts. In addition, the Company issued an additional 1.1 million shares pursuant to its dividend reinvestment program (the "DRIP"). On April 7, 2015, in anticipation of the Listing, the Company announced the suspension of the DRIP. On May 7, 2015, the Company filed a post-effective amendment to its registration statement on Form S-11 (File No. 001-37390) (as amended, the "Registration Statement") to deregister the unsold shares registered under the Registration Statement. In connection with the Listing, the Company offered to purchase up to 11.9 million shares of its Common Stock at a price of $10.50 per share (the “Tender Offer”). As a result of the Tender Offer, on July 6, 2015, the Company purchased approximately 11.9 million shares of its Common Stock at a price of $10.50 per share, for an aggregate amount of $125.0 million, excluding fees and expenses relating to the Tender Offer and including fractional shares repurchased thereafter. Substantially all of the Company's business is conducted through Global Net Lease Operating Partnership, L.P. (the "OP"), a Delaware limited partnership. At Listing, the OP had issued 1,809,678 units of limited partnership interests ("OP Units") to limited partners other than the Company, of which 1,461,753 OP Units were issued to Global Net Lease Advisors, LLC (the "Advisor"), 347,903 OP Units were issued to Moor Park Capital Partners LLP (the "Service Provider"), and 22 OP Units were issued to Global Net Lease Special Limited Partner, LLC (the "Special Limited Partner") (see Note 10 — Related Party Transactions). In accordance with the limited partnership agreement of the OP, a holder of OP Units has the right to convert OP Units, at the Company's option, for a corresponding number of shares of the Company's Common Stock or the cash value of those corresponding shares. The remaining rights of the limited partner interests are limited and do not include the ability to replace the general partner or to approve the sale, purchase or refinancing of the OP's assets. Subsequent to the Listing, all OP Units issued to the Advisor were transferred to individual investors. On September 2, 2016, 1,264,148 of the OP Units were converted into Common Stock, of which 916,231 were issued to individual investors, 347,903 were issued to the Service Provider, and 14 were issued to the Special Limited Partner. The Company had 545,530 of OP Units outstanding as of September 30, 2016. The Company has no direct employees. The Company has retained the Advisor to manage the Company's affairs on a day-to-day basis. The properties are managed and leased by Global Net Lease Properties, LLC (the "Property Manager"). The Advisor, Property Manager and Special Limited Partner are under common control with the parent of AR Capital Global Holdings, LLC (the "Sponsor"), as a result of which they are related parties. These related parties receive compensation and fees for various services provided to the Company. The Advisor has entered into a service provider agreement with the Service Provider, pursuant to which the Service Provider provides, subject to the Advisor's oversight, certain real estate related services, as well as sourcing and structuring of investment opportunities, performance of due diligence, and arranging debt financing and equity investment syndicates, solely with respect to investments in Europe. The Company and American Realty Capital Global Trust II, Inc. ("Global II"), an affiliate of the Sponsor, have entered into an agreement and plan of merger, dated as of August 8, 2016, as it may be amended from time to time ("the Merger Agreement). Pursuant to the Merger Agreement, Global II will merge with and into a direct wholly owned subsidiary of the Company (the "Merger Sub"), at which time the separate existence of Global II will cease and the Company will be the parent of the Merger Sub (the "Merger"). In addition, pursuant to the Merger Agreement, American Realty Capital Global II Operating Partnership, L.P., a Delaware limited partnership and the operating partnership of Global II (the "Global II OP"), will merge with the OP, with the OP being the surviving entity (the "Partnership Merger" and together with the Merger, the "Mergers"). Pursuant to the Merger Agreement, each outstanding share of Global II's common stock, including restricted shares of common stock, par value $0.01 per share ("Global II Common Stock"), other than shares owned by the Company, any subsidiary of the Company or any wholly owned subsidiary of Global II, will be converted into the right to receive 2.27 shares of Common Stock of the Company (the "Merger Consideration"). In addition, in connection with the Partnership Merger, each outstanding unit of limited partnership interest, including the Class B Units (as defined in Note 10 — Related Party Transactions), of the Global II OP will be converted into the right to receive 2.27 shares of the Company's Common Stock. Based on the closing price of the Company's Common Stock on October 31, 2016 of $7.41 and the number of shares of outstanding Global II Common Stock on September 30, 2016, the aggregate value of the Merger Consideration to be received by Global II stockholders would be approximately $212.6 million. The completion of the Mergers are subject to various conditions, including, among other things, the approval of the Mergers and the other transactions contemplated by the Merger Agreement by the affirmative vote of a majority of the votes of the Company’s stockholders cast at a meeting of the Company’s common stockholders, a quorum being present, and the approval of the Merger and the other transactions contemplated by the Merger Agreement by Global II’s common stockholders holding a majority of the outstanding shares of Global II Common Stock. The Merger Agreement also includes certain termination rights for both the Company and Global II and provides that, in connection with the termination of the Merger Agreement, under specified circumstances, the Company or Global II may be required to pay to the other party reasonable out-of-pocket transaction expenses up to an aggregate amount of $5.0 million. If Global II, or the Company in certain circumstances, terminates the Merger Agreement, Global II would be required to pay the Company a termination fee equal to $6.0 million. The Company and Global II each were sponsored, directly or indirectly, by the Sponsor. The Sponsor and its affiliates provide investment and advisory services to the Company and Global II pursuant to written advisory agreements. In connection with, and subject to the terms and conditions of, the Merger Agreement, the Sponsor and its affiliates will have the vesting of certain of their restricted interests in Global II and the Global II OP accelerated.
