Accounting Policies [Abstract]
Organization	Note 1 — Organization
	American Realty Capital Properties, Inc. (the “General Partner” or “ARCP”) is a self-managed Maryland corporation incorporated on December 2, 2010 that qualified as a real estate investment trust (“REIT”) for U.S. federal income tax purposes beginning in the taxable year ended December 31, 2011. On September 6, 2011, the Company completed its initial public offering (the “IPO”). The Company’s common stock trades on the NASDAQ Global Select Market (“NASDAQ”) under the symbol “ARCP.”
	ARCP is the general partner of ARC Properties Operating Partnership, L.P. (together with its subsidiaries, the “Operating Partnership” or the “OP”), a Delaware limited partnership, which was formed on January 13, 2011 to conduct the business of acquiring, owning and operating single-tenant, freestanding commercial real estate properties. The Operating Partnership is the entity through which substantially all of the General Partner’s operations are conducted. Together, the General Partner, with the Operating Partnership and their consolidated subsidiaries are known as the “Company.” The term the “Company” refers to the General Partner and the Operating Partnership collectively.
	The actions of the Operating Partnership and its relationship with ARCP are governed by that certain Third Amended and Restated Agreement of Limited Partnership (the “LPA”), effective as of January 3, 2014, as amended. The General Partner does not have any significant assets other than its investment in the Operating Partnership. Therefore, the assets and liabilities of the General Partner and the Operating Partnership are substantially the same. Additionally, pursuant to the LPA, all administrative expenses and expenses associated with the formation and continuity of existence and operation of the General Partner incurred by the General Partner on the Operating Partnership’s behalf shall be treated as expenses of the Operating Partnership. Further, when the General Partner issues any equity instrument that has been approved by the General Partner’s board of directors to date, the LPA requires the Operating Partnership to issue the General Partner equity instruments with substantially similar terms, to protect the integrity of the Company’s umbrella partnership REIT structure, pursuant to which each holder of interests in the Operating Partnership has a proportionate economic interest in the Operating Partnership reflecting its capital contributions thereto. The LPA also provides that the Operating Partnership issue debt that mirrors debt issued by ARCP. The LPA will be amended to provide for the issuance of any additional class of equivalent equity instruments to the extent the General Partner’s board of directors authorizes the issuance of any new class of equity securities.
	The Company operates through two business segments, Real Estate Investment (“REI”) and private capital management, Cole Capital (“Cole Capital”), as further discussed in Note 6 — Segment Reporting. Substantially all of the Company’s REI segment is conducted through the OP. ARCP is the sole general partner and holder of 97.3% of the common equity interests in the OP as of September 30, 2014. As of September 30, 2014, certain affiliates of ARCP and certain unaffiliated investors are limited partners and owners of 1.7% and 1.0%, respectively, of the common equity interests in the OP. Under the LPA, after holding units of limited partner interests in the OP (“OP Units”) for a period of one year, unless otherwise consented to by ARCP, holders of OP Units have the right to redeem the OP Units for the cash value of a corresponding number of shares of ARCP’s common stock or, at the option of ARCP, a corresponding number of shares of ARCP’s common stock. The remaining rights of the holders of OP Units are limited, however, and do not include the ability to replace the general partner or to approve the sale, purchase or refinancing of the OP’s assets. Substantially all of Cole Capital’s business segment is conducted through Cole Capital Advisors, Inc. (“CCA”), an Arizona corporation and a wholly owned subsidiary of the OP. CCA is treated as a taxable REIT subsidiary (“TRS”) under Section 856 of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”).
	Prior to January 8, 2014, ARC Properties Advisors, LLC (the “Former Manager”), a wholly owned subsidiary of AR Capital, LLC (“ARC”), managed the Company’s affairs on a day-to-day basis, with the exception of certain acquisition, accounting and portfolio management services performed by employees of the Company. In August 2013, the Company’s board of directors determined that it was in its best interest and the best interest of its stockholders to become self-managed, and the Company completed its transition to self-management on January 8, 2014. In connection with becoming self-managed, ARCP terminated the management agreement with its Former Manager and ARCP and the OP entered into employment and incentive compensation arrangements with ARCP executives. See Note 20 — Related Party Transactions and Arrangements for further discussion.
	The Company has advanced its investment objectives by not only growing its net lease portfolio through granular, self-originated acquisitions, but also through strategic mergers and acquisitions. See Note 3 — Mergers and Acquisitions for further discussion.

Accounting Changes and Error Corrections [Abstract]
Restatement of Previously Issued Consolidated Financial Statements	Note 2 — Restatement of Previously Issued Consolidated Financial Statements
	The Company has restated its consolidated balance sheets as of September 30, 2013 and December 31, 2013 and its consolidated statements of operations and consolidated statements of comprehensive loss for the three and nine months ended September 30, 2013. In addition, the Company has restated its consolidated statements of changes in equity and consolidated statement of cash flows for the nine months ended September 30, 2013 along with certain restated notes to such consolidated financial statements. As disclosed in Note 3 — Mergers and Acquisitions, the financial statements have been recast in applying the carryover basis of accounting to include the effects of the Company’s merger with American Realty Capital Trust IV, Inc. (“ARCT IV”). As it pertains to Note 2 and the disclosures contained herein, the use of the reference to the “Company” means “ARCP” only when describing the restatement of the consolidated financial statements as of and for the period ended September 30, 2013.
	The Company determined that the restatement was necessary after an investigation was conducted by the Audit Committee of the Company’s Board of Directors (the “Audit Committee”) with the assistance of independent counsel and forensic accountants. The Audit Committee initiated the investigation in response to concerns regarding accounting practices and other matters that were first reported to it on September 7, 2014. The restatement corrects errors that were identified as a result of the investigation, as well as certain other errors that were identified by the Company. The Company has determined that it would be appropriate to correct such errors.
	Year ended December 31, 2013
	Corrections to the Company’s financial statements for the year ended December 31, 2013 are detailed within Amendment No. 2 to the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2013 filed with the U.S. Securities and Exchange Commission (“SEC”) (the “Amended 10-K”). The corrections relate primarily to bonus accruals, real estate impairments, goodwill, merger and acquisition costs, transfer tax accrual and non-controlling interests.
	Nine months Ended September 30, 2013 Error Corrections
	Merger and Other Non-routine Transaction Related
	In light of the findings of the investigation conducted by the Audit Committee, the Company performed an internal review of all acquisition, merger and other non-routine transaction related expenses. The work resulted in the identification of the following errors:
		•		The Company identified $13.0 million of management fees that were improperly classified as merger and other non-routine transaction related expenses. Such amounts have been properly classified as operating fees to affiliates in the nine months ended September 30, 2013. No such expenses were identified in the three months ended September 30, 2013.
		•		Upon consummation of the Company’s merger with American Realty Capital Trust III, Inc. (“ARCT III”) (Note 3 —Mergers and Acquisitions), the OP entered into an agreement with an affiliate to acquire certain furniture, fixtures, equipment (“FF&E”) and other assets. The Company originally capitalized $4.1 million of FF&E costs and expensed $1.7 million of FF&E costs in the nine months ended September 30, 2013. The Company has concluded that there was no evidence of the receipt and it could not support the value of the FF&E. As such, the Company has expensed the amount originally capitalized and recognized the expense in merger and other non-routine transaction related expense for the nine months ended September 30, 2013. See Note 20 — Related Party Transactions and Arrangements for further discussion. No such expenses were identified in the three months ended September 30, 2013.
		•		The Company improperly classified $0.3 million and $6.1 million of expenses as “merger-related” for the three and nine months ending September 2013, respectively. As such, the amounts have been reclassified from merger and other non-routine transaction related expenses to general and administrative expenses.
		•		The Company identified $1.2 million and $2.2 million of expenses that were improperly classified as merger and other transaction related expenses that should have been capitalized as deferred financing costs and amortized accordingly for the three and nine months ended September 30, 2013, respectively. As such, an adjustment to properly record and amortize the deferred financing costs has been made.
		•		The Company has determined that it should have recorded a controlling interest tax liability totaling $1.1 million upon consummation of the mergers with ARCT III. The accrual and corresponding merger and other non-routine transaction related expense are recorded for the nine months ended September 30, 2013. No such expenses were identified in the three months ended September 30, 2013.
		•		The Company identified net amounts of $167,000 and $254,000 of merger and other non-routine transaction related expenses that were recorded in the incorrect period. As such, the Company has decreased merger and other non-routine transaction related expenses by these amounts in the three and nine months ended September 30, 2013, respectively.
	The Company has updated the caption from “merger and other transaction related” to “merger and other non-routine transactions” to appropriately include non-recurring costs that may not have been incurred solely for a merger transaction. See Note 4 — Summary of Significant Accounting Policies for a further breakout of the merger costs and other one-time costs.
	Management Fees to Affiliate
	The Company identified $0.5 million of operating fees to an affiliate that was improperly recorded in the nine months ended September 30, 2013. Therefore, the Company decreased operating fees to affiliate by this amount for the nine months ended September 30, 2013. No such expenses were identified in the three months ended September 30, 2013.
	General and Administrative
	The Company originally reported $7.2 million and $11.5 million during the three and nine months ended September 30, 2013, respectively, in equity-based compensation in its own line item, however it now reports such compensation as general and administrative expenses.
	Impairment of Real Estate
	The Company originally believed that the risk of impairment of its real estate and related assets was mitigated by the fact that substantially all of the Company’s real estate portfolio had been acquired in 2012 and 2013. As a result, the Company had failed to monitor events and changes in circumstances that could indicate that the carrying amount of its real estate and related assets may not be recoverable. The Company performed a detailed analysis of the portfolio in connection with the restatement and noted certain properties with impairment indicators. The Company assessed the recoverability of the carrying amounts as of the date in which the impairment indicators existed. Based on this assessment, the Company noted one property with a carrying amount in excess of the fair value of its expected undiscounted cash flows as of September 30, 2013. As a result, the Company reduced the carrying amount of the real estate and related net assets to their estimated fair values by recognizing an impairment loss of $2.1 million for the three and nine months ended September 30, 2013.
	Net Loss Attributable to Non-Controlling Interests
	The original calculation of the net loss attributable to non-controlling interest holders for the three and nine months ended September 30, 2013 excluded expenses that were improperly recorded at the Company’s level. These expenses were incurred by the OP, and therefore should have been included in the Company’s determination of the net loss attributable to its non-controlling interest holders. In addition, the net loss attributable to the non-controlling interest holders has been adjusted to reflect the impact of the cumulative restatement adjustments discussed and presented herein. As a result, the 2013 restated consolidated financial statements reflect an increase of $2.9 million and $6.7 million for net loss attributable to non-controlling interest holders and corresponding decreases in net loss attributable to stockholders during the three and nine months ended September 30, 2013, respectively.
	Due to Affiliates
	Amounts due to affiliates of the Company of $6.1 million, previously reported in accounts payable and accrued expenses, are now reported on a separate line item on the consolidated restated balance sheet as of September 30, 2013.
	Other Changes
	Along with restating the consolidated financial statements to correct the errors discussed above, the Company recorded adjustments for certain previously identified immaterial accounting errors related to the three and nine months ended September 30, 2013 that arose in the normal course of business. In connection with the original financial statement issuance, the Company assessed the impact of these immaterial errors and concluded that they were not material, individually or in the aggregate, to the consolidated unaudited financial statements for the nine months ended September 30, 2013. However, in conjunction with the restatement, the Company determined that it would be appropriate to correct such errors.
	The Company also recorded certain reclassifications to conform the presentation of its restated consolidated statement of operations for the three and nine months ended September 30, 2013 to the current period classification and maintain comparability.

Business Combinations [Abstract]
Mergers and Acquisitions	Note 3 — Mergers and Acquisitions
	Mergers and Significant Acquisitions
	American Realty Capital Trust III, Inc. Merger
	On December 14, 2012, the Company entered into an Agreement and Plan of Merger (the “ARCT III Merger Agreement”) with ARCT III and certain subsidiaries of each company. The ARCT III Merger Agreement provided for the merger of ARCT III with and into a subsidiary of the Company (the “ARCT III Merger”). The ARCT III Merger was consummated on February 28, 2013.
	Pursuant to the terms and subject to the conditions set forth in the ARCT III Merger Agreement, each outstanding share of common stock of ARCT III, including restricted shares which became vested, was converted into the right to receive (i) 0.95 of a share of ARCP’s common stock (the “ARCT III Exchange Ratio”) or (ii) $12.00 in cash. In addition, each outstanding unit of equity ownership of ARCT III’s operating partnership (the “ARCT III OP”) was converted into the right to receive 0.95 of the same class of unit of equity ownership in the OP.
	Upon the closing of the ARCT III Merger on February 28, 2013, the Company paid an aggregate of $350 million in cash for 29.2 million shares that elected cash consideration, or 16.5% of the then outstanding shares of ARCT III’s common stock (which is equivalent to 27.7 million shares of ARCP’s common stock based on the ARCT III Exchange Ratio). In addition, 140.7 million shares of ARCP’s common stock were issued in exchange for 148.1 million shares of ARCT III’s common stock adjusted for the ARCT III Exchange Ratio. In accordance with the LPA, the OP issued a corresponding number of General Partner OP Units to ARCP when ARCP issued common stock to former common stockholders of ARCT III.
	Upon the consummation of the ARCT III Merger, American Realty Capital Trust III Special Limited Partner, LLC (the “ARCT III Special Limited Partner”), the holder of the special limited partner interest in the ARCT III OP, was entitled to subordinated distributions of net sales proceeds from the ARCT III OP which resulted in the issuance of units of limited partner interests in the ARCT III OP which, when after applying the ARCT III Exchange Ratio, resulted in the issuance of an additional 7.3 million OP Units to affiliates of the Company’s Former Manager. The parties had agreed that such OP Units would be subject to a minimum one-year holding period from the date of issuance before being redeemable by the holder for cash or, at the option of ARCP, common stock of ARCP.
	Also in connection with the ARCT III Merger, the Company entered into an agreement with ARC and its affiliates to internalize certain functions performed by them prior to the ARCT III Merger, reduce certain fees paid to affiliates and pay certain merger related fees. See Note 20 — Related Party Transactions and Arrangements.
	Accounting Treatment for the ARCT III Merger
	The Company and ARCT III, from inception to the ARCT III Merger Date, were considered to be entities under common control. Both entities’ advisors were wholly owned subsidiaries of ARC. ARC and its related parties had significant ownership interests in the Company and ARCT III through the ownership of shares of common stock and other equity interests. In addition, the advisors of the Company and ARCT III were contractually eligible to receive potential fees for their services to both of the companies including asset management fees, incentive fees and other fees and continued to receive fees from the Operating Partnership, on behalf of ARCP, prior to ARCP’s transition to self-management. Due to the significance of these fees, the advisors and ultimately ARC were determined to have a significant economic interest in both companies in addition to having the power to direct the significant activities of the companies through advisory/management agreements, which qualified them as affiliated companies under common control in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The acquisition of an entity under common control is accounted for on the carryover basis of accounting, whereby the assets and liabilities of the companies are recorded upon the merger on the same basis as they were carried by the companies on the ARCT III Merger Date. In addition, U.S. GAAP requires the Company to present historical financial information for all periods that entities were under common control. Therefore, the accompanying consolidated financial statements including the notes thereto are presented as if the ARCT III Merger had occurred at inception.
	CapLease, Inc. Merger
	On May 28, 2013, the Company entered into an Agreement and Plan of Merger (the “CapLease Merger Agreement”) with CapLease, a Maryland corporation, and certain subsidiaries of each company. The CapLease Merger Agreement provided for the merger of CapLease with and into a subsidiary of the Company (the “CapLease Merger”).
	On November 5, 2013, the Company completed the CapLease Merger. Pursuant to the terms of the CapLease Merger Agreement, each outstanding share of common stock of CapLease, other than shares owned by the Company, CapLease or any of their respective wholly owned subsidiaries, was converted into the right to receive $8.50. Each outstanding share of preferred stock of CapLease, other than shares owned by the Company, CapLease or any of their respective wholly owned subsidiaries, was converted into the right to receive an amount in cash equal to the sum of $25.00 plus all accrued and unpaid dividends on such shares of preferred stock. In addition, in connection with the merger of Caplease, LP with and into the OP, each outstanding unit of equity ownership of CapLease’s operating partnership, other than units owned by CapLease, the OP, or any other of their respective wholly owned subsidiaries, was converted into the right to receive $8.50. Shares of CapLease’s outstanding restricted stock was accelerated and became fully vested, and restricted stock and any outstanding performance shares were fully earned and received $8.50 per share. In total, cash consideration of $920.7 million was paid to CapLease’s common and preferred shareholders.
	Accounting Treatment for the CapLease Merger
	The CapLease Merger has been accounted for under the acquisition method of accounting under U.S. GAAP. Under the acquisition method of accounting, the assets acquired and liabilities assumed from CapLease have been recorded as of the acquisition date at their respective fair values. Any excess of purchase price over the fair values is recorded as goodwill. Results of operations for CapLease are included in the Company’s consolidated financial statements from the date of acquisition.
	American Realty Capital Trust IV, Inc. Merger
	On July 1, 2013, the Company entered into an Agreement and Plan of Merger, as amended on October 6, 2013 and October 11, 2013 (the “ARCT IV Merger Agreement”), with ARCT IV, and certain subsidiaries of each company. The ARCT IV Merger Agreement provided for the merger of ARCT IV with and into a subsidiary of the OP (the “ARCT IV Merger”). The ARCT IV Merger was consummated on January 3, 2014 (the “ARCT IV Merger Date”).
	Pursuant to the terms of the ARCT IV Merger Agreement, as amended, each outstanding share of common stock of ARCT IV, including unvested restricted shares that vested in conjunction with the ARCT IV Merger, was exchanged for (i) $9.00 in cash, (ii) 0.5190 of a share of ARCP’s common stock (the “ARCT IV Exchange Ratio”) and (iii) 0.5937 of a share of a new series of preferred stock designated as the 6.70% Series F Cumulative Redeemable Preferred Stock (“Series F Preferred Stock”) and each outstanding unit of ARCT IV’s operating partnership (each, an “ARCT IV OP Unit”), other than ARCT IV OP Units held by American Realty Capital Trust IV Special Limited Partner, LLC (the “ARCT IV Special Limited Partner”), and American Realty Capital Advisors IV, LLC (the “ARCT IV Advisor”) was exchanged for (i) $9.00 in cash, (ii) 0.5190 of a Limited Partner OP Unit and (iii) 0.5937 of a Limited Partner OP Unit designated as Series F Preferred Units (“Limited Partner Series F OP Units”). In total, the Operating Partnership, on ARCP’s behalf, paid $651.4 million in cash, ARCP issued 36.9 million shares of common stock and 42.2 million shares of Series F Preferred Stock to the former ARCT IV shareholders, and the Operating Partnership issued 0.7 million units of Limited Partner Series F OP units and 0.6 million Limited Partner OP Units to the former ARCT IV OP Unit holders in connection with the consummation of the ARCT IV Merger. In addition, each outstanding ARCT IV Class B Unit (as defined below) and each outstanding ARCT IV OP Unit held by the ARCT IV Special Limited Partner and the ARCT IV Advisor was converted into 2.3961 Limited Partner OP Units, resulting in the Company issuing 1.2 million Limited Partner OP Units. In accordance with the LPA, the OP issued a corresponding number of General Partner OP Units and Series F Preferred Units to ARCP when shares of ARCP’s common stock and Series F Preferred Stock were issued to former common stockholders of ARCT IV, respectively.
	On January 3, 2014, the OP entered into a Contribution and Exchange Agreement (the “ARCT IV Contribution and Exchange Agreement”) with the ARCT IV OP, the ARCT IV Special Limited Partner and ARC Real Estate Partners, LLC (“ARC Real Estate”), an entity under common ownership with the Former Manager. The ARCT IV Special Limited Partner was entitled to receive certain distributions from the ARCT IV OP, including the subordinated distribution of net sales proceeds resulting from an “investment liquidity event” (as defined in the agreement of limited partnership of the ARCT IV OP). The ARCT IV Merger constituted an “investment liquidity event,” as a result of which the ARCT IV Special Limited Partner, in connection with management’s successful attainment of the 6.0% performance hurdle and the return to ARCT IV’s stockholders of approximately $358.3 million in addition to their initial investment, was entitled to receive a subordinated distribution of net sales proceeds from the ARCT IV OP equal to approximately $63.2 million. Pursuant to the ARCT IV Contribution and Exchange Agreement, the ARCT IV Special Limited Partner contributed its interest in the ARCT IV OP, inclusive of the subordinated distribution proceeds received, to the ARCT IV OP in exchange for 2.8 million equity units of the ARCT IV OP, based on a price per share of $22.50. The fair value of these units at date of issuance was $78.2 million and has been included in merger and other non-routine transactions in the accompanying consolidated statement of operations for the nine months ended September 30, 2014. Upon consummation of the ARCT IV Merger, these equity units were immediately converted to 6.7 million Limited Partner OP Units after application of the exchange ratio of 2.3961 per ARCT IV OP Unit. In conjunction with the ARCT IV Merger Agreement, the ARCT IV Special Limited Partner agreed to a minimum two-year holding period for these Limited Partner OP Units before being redeemable by the holder for cash or, at the option of the General Partner, the common stock of ARCP.
	In addition, as part of the ARCT IV Contribution and Exchange Agreement, ARC Real Estate Partners, LLC, contributed $750,000 in cash to the ARCT IV OP, effective prior to the consummation of the ARCT IV Merger, in exchange for ARCT IV OP Units. Upon the consummation of the ARCT IV Merger, these equity units converted at an exchange ratio of 2.3961 Limited Partner OP Units per ARCT IV OP Unit, resulting in the Operating Partnership issuing 0.1 million Limited Partner OP Units to ARC Real Estate Partners, LLC.
	Accounting Treatment for the ARCT IV Merger
	The Company and ARCT IV, from inception to the ARCT IV Merger Date, were considered to be entities under common control. Both entities’ advisors were wholly owned subsidiaries of ARC. ARC and its related parties had ownership interests in the Company and ARCT IV through the ownership of shares of common stock, OP Units and other equity interests. In addition, the advisors of both entities were contractually eligible to receive potential fees for their services to both of the companies including asset management fees, incentive fees and other fees and had continued to receive fees from the OP prior to ARCP’s transition to self-management. Due to the significance of these fees, the advisors and ultimately ARC were determined to have a significant economic interest in both companies in addition to having the power to direct the activities of the companies through advisory/management agreements, which qualified them as affiliated companies under common control in accordance with U.S. GAAP. The acquisition of an entity under common control is accounted for on the carryover basis of accounting, whereby the assets and liabilities of the companies are recorded upon the merger on the same basis as they were carried by the companies on the ARCT IV Merger Date. In addition, U.S. GAAP requires the Company to present historical financial information for all periods that entities were under common control. Therefore, the accompanying consolidated financial statements including the notes thereto are presented as if the ARCT IV Merger, including the impact of the equity transactions entered into to consummate the merger, had occurred at inception.
	Fortress Portfolio Acquisition
	On July 24, 2013, ARC and another related entity, on behalf of the Company and certain other entities sponsored directly or indirectly by ARC, entered into a purchase and sale agreement with affiliates of funds managed by Fortress Investment Group LLC (“Fortress”) for the purchase of 196 properties owned by Fortress, for an aggregate contract purchase price of $972.5 million, subject to adjustments set forth in the purchase and sale agreement and exclusive of closing costs, which were allocated to the Company based on the pro rata fair value of the properties acquired by the Company relative to the fair value of all 196 properties to be acquired from Fortress. Of the 196 properties, 120 properties were allocated to the Company (the “Fortress Portfolio”). On October 1, 2013, the Company closed on 41 of the 120 properties with a total purchase price of $200.3 million, exclusive of closing costs. During quarter ended March 31, 2014, the Company closed the acquisition of the remaining 79 properties in the Fortress Portfolio on January 8, 2014, for an aggregate contract purchase price of $400.9 million, exclusive of closing costs. The total purchase price of the Fortress Portfolio was $601.2 million, exclusive of closing costs.
	Cole Real Estate Investments, Inc. Merger
	On October 22, 2013, ARCP entered into an agreement and plan of merger (the “Cole Merger Agreement”) with Cole Real Estate Investments, Inc. (“Cole”), a Maryland corporation, and a wholly owned subsidiary of the Company. The Cole Merger Agreement provided for the merger of Cole with and into a wholly owned subsidiary of the Company (the “Cole Merger”). The Operating Partnership consummated the Cole Merger on February 7, 2014 (the “Cole Acquisition Date”).
	Pursuant to the terms of the Cole Merger Agreement, each share of common stock of Cole issued and outstanding immediately prior to the effectiveness of the Cole Merger, including unvested restricted stock units and performance stock units that vested in conjunction with the Cole Merger, other than shares owned by the Company, any subsidiary of the Company or any wholly owned subsidiary of Cole, was converted into the right to receive either (i) 1.0929 shares of ARCP’s common stock (the “Stock Consideration”) or (ii) $13.82 in cash (the “Cash Consideration” and together with the Stock Consideration, the “Merger Consideration”). Approximately 98% of all outstanding Cole shareholders received Stock Consideration and approximately 2% of outstanding Cole shareholders elected to receive Cash Consideration, pursuant to the terms of the Cole Merger Agreement, resulting in ARCP issuing approximately 520.8 million shares of common stock and paying $181.8 million in cash to Cole’s shareholders based on their elections. In accordance with the LPA, the Operating Partnership issued a corresponding number of General Partner OP Units to ARCP when shares of ARCP’s common stock were issued to former common stockholders of Cole.
	In addition, ARCP issued approximately 2.8 million shares of common stock, in the aggregate, to certain executives of Cole pursuant to letter agreements entered into between the Company and such individuals, concurrently with the execution of the Cole Merger Agreement, as previously disclosed by the Company. Additionally, effective as of the Cole Acquisition Date, ARCP issued, but has not yet allocated, 365,321 shares with dividend equivalent rights commensurate with ARCP’s common stock. In accordance with the LPA, the Operating Partnership issued a corresponding number of General Partner OP Units to ARCP when shares of ARCP’s common stock were issued to former executives of Cole.
	Accounting Treatment for the Cole Merger
	The Cole Merger has been accounted for under the acquisition method of accounting under U.S. GAAP. Under the acquisition method of accounting, the assets acquired and liabilities assumed from Cole have been recorded as of the acquisition date at their respective fair values. Any excess of purchase price over the fair values is recorded as goodwill. Results of operations for Cole are included in the Company’s consolidated financial statements subsequent to the Cole Acquisition Date.
	Inland Portfolio Acquisition
	On August 8, 2013, ARC and another related entity, on behalf of the Company and certain other entities sponsored directly or indirectly by ARC, entered into a purchase and sale agreement with Inland American Real Estate Trust, Inc. (“Inland”) for the purchase of the equity interests of 67 companies owned by Inland for an aggregate contract purchase price of approximately $2.3 billion, subject to adjustments set forth in the purchase and sale agreement and exclusive of closing costs. Of the 67 companies, the equity interests of 10 companies (the “Inland Portfolio”) were allocated to the Company for a purchase price of approximately $501.0 million, subject to adjustments set forth in the purchase and sale agreement and exclusive of closing costs, which were allocated to the Company based on the pro rata fair value of the Inland Portfolio relative to the fair value of all 67 companies to be acquired from Inland by the Operating Partnership, on the Company’s behalf, and the other entities sponsored directly or indirectly by ARC. The Inland Portfolio is comprised of 33 properties. As of September 30, 2014, the Company had closed on 32 of the 33 properties for a total purchase price of $288.2 million, exclusive of closing costs. The Company will not close on the remaining one property.
	Cole Credit Property Trust, Inc. Merger
	On March 17, 2014, the Company and a wholly owned subsidiary entered into an Agreement and Plan of Merger (the “CCPT Merger Agreement”) with Cole Credit Property Trust, Inc., a Maryland corporation (“CCPT”). The CCPT Merger Agreement provided for the merger of CCPT with and into a subsidiary of the Company (the “CCPT Merger”). The Company consummated the CCPT Merger on May 19, 2014 (the “CCPT Acquisition Date”). The estimated fair value of the consideration transferred at the CCPT Acquisition Date totaled approximately $73.2 million, which was paid in cash.
	Pursuant to the CCPT Merger Agreement, the Company commenced a cash tender offer to purchase all of the outstanding shares of common stock of CCPT (the “CCPT Common Stock”) (other than shares owned by CCPT, the Company or any subsidiary of the Company), upon the terms and subject to the conditions set forth in the Offer to Purchase, dated March 31, 2014, and the related Letter of Transmittal (together with any amendments or supplements to the foregoing, the “Offer”), at a price of $7.25 per share (the “Offer Price”), net to the seller in cash, without interest, less any applicable withholding tax. On May 19, 2014, the Company accepted for payment and paid for all shares of CCPT Common Stock that were validly tendered in the Offer. As of the expiration of the Offer, a total of 7,735,069 shares of CCPT Common Stock were validly tendered and not withdrawn, representing approximately 77% of the shares of CCPT Common Stock outstanding.
	Immediately following the acceptance for payment and payment for the shares of CCPT Common Stock that were validly tendered in the Offer, the Company exercised its option (the “Top-Up Option”), granted pursuant to the CCPT Merger Agreement, to purchase, at a price per share equal to the Offer Price, 13,457,874 newly issued shares of CCPT Common Stock (collectively, the “Top-Up Shares”). The Top-Up Shares, taken together with the shares of CCPT Common Stock owned, directly or indirectly, by the Company and its subsidiaries immediately following the acceptance for payment and payment for the shares of CCPT Common Stock that were validly tendered in the Offer, constituted one share more than 90% of the outstanding shares of CCPT Common Stock (after giving effect to the issuance of all shares subject to the Top-Up Option), the applicable threshold required to effect a short-form merger under applicable Maryland law without stockholder approval.
	Following the consummation of the Offer and the exercise of the Top-Up Option, in accordance with the CCPT Merger Agreement, the Company completed its acquisition of CCPT by effecting of a short-form merger under Maryland law, pursuant to which CCPT was merged with and into a subsidiary of the Company, with the subsidiary surviving the merger as a wholly owned subsidiary of the Company. The CCPT Merger became effective following the filing of the Articles of Merger with the State Department of Assessments and Taxation of Maryland and the filing of the Certificate of Merger with the Secretary of State of the State of Delaware with an effective date of May 19, 2014 (the “Effective Time”).
	At the Effective Time, each share of CCPT Common Stock not purchased in the Offer (other than shares held by the CCPT, the Company or any subsidiary of the Company, which were automatically canceled and retired and ceased to exist) was converted into the right to receive an amount, in cash and without interest, equal to the Offer Price.
	Accounting Treatment for the CCPT Merger
	The CCPT Merger has been accounted for under the acquisition method of accounting under U.S. GAAP. Under the acquisition method of accounting, the assets acquired and liabilities assumed from CCPT have been recorded as of the acquisition date at their respective fair values. Any excess of purchase price over the fair values is recorded as goodwill. Results of operations for CCPT are included in the Company’s consolidated financial statements subsequent to the CCPT Acquisition Date.
	Red Lobster Portfolio Acquisition
	On May 15, 2014, the Operating Partnership, through a wholly owned subsidiary, entered into a master purchase agreement to acquire over 500 properties, substantially all of which are operating as Red Lobster® restaurants (the “Red Lobster Portfolio”) from a third party. The transaction was structured as a sale-leaseback in which the Operating Partnership agreed to purchase the Red Lobster Portfolio and would immediately lease the portfolio back to the third party pursuant to the terms of multiple master leases (the “Master Leases”). The overall sale-leaseback transaction consisted of 522 Red Lobster® restaurants and 20 other branded restaurant properties for a purchase price of $1.7 billion. The Company closed the Red Lobster Portfolio acquisition in the third quarter of 2014.
	Abandoned Spin-off of Multi-Tenant Shopping Center Portfolio
	On March 13, 2014, the Company announced its intention to spin off its multi-tenant shopping center business (“MT Spin-off”) into a publicly traded REIT, American Realty Capital Centers, Inc., which was expected to operate under the name “ARCenters” and to trade on the NASDAQ Global Market under the symbol “ARCM.” The OP was expected to retain 25% ownership of ARCM. The spin-off was expected to be effectuated through a pro rata taxable special distribution of one share of ARCM common stock for every 10 shares of the Company’s common stock and every 10 OP Units held by third parties in the OP. On April 4, 2014, ARCM filed a Registration Statement on Form 10 to register ARCM’s common stock, par value $0.01 per share, pursuant to Section 12(b) of the Exchange Act so that, upon consummation of the spin-off, shares of ARCM received by holders of the Company’s common stock, or OP Units, as applicable, could freely trade their newly received ARCM common stock. ARCM was expected to be externally managed by the Company. On May 21, 2014, the Company announced that it had reassessed its plans for the multi-tenant shopping center portfolio and entered into a letter of intent to sell such portfolio to Blackstone, expecting to finalize pertinent documentation related thereto within 30 days of such date. The properties included in such sale were the same properties that would have been spun off into ARCM and, consequently, the Company abandoned its proposed spin-off at such time. On June 11, 2014, indirect subsidiaries of the Company entered into an Agreement of Purchase and Sale with BRE DDR Retail Holdings III LLC, an entity indirectly jointly owned by affiliates of Blackstone Real Estate Partners VII L.P. and DDR Corp., pursuant to which the parties definitively documented the sale of the Company’s multi-tenant shopping center portfolio. The properties to be sold pursuant to such agreement were the same properties that the Company had previously intended to spin off into an externally managed, NASDAQ traded REIT, American Realty Capital Centers, Inc. In light of the Company’s entry into such agreement, it abandoned its previously contemplated spin-off.

Summary of Significant Accounting Policies	9 Months Ended

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 4 — Summary of Significant Accounting Policies
	The consolidated financial statements of the Company included herein include the accounts of ARCP and its consolidated subsidiaries, including the Operating Partnership. All intercompany amounts have been eliminated. The financial statements were prepared in conformity with U.S. GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The information furnished includes all adjustments and accruals of a normal recurring nature, which, in the opinion of management, are necessary for a fair presentation of results for the interim periods. The results of operations for the three and nine months ended September 30, 2014 are not necessarily indicative of the results for the entire year or any subsequent interim period.
	These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2013 of the Company, which are included in the Amended 10-K. There have been no significant changes to these policies during the nine months ended September 30, 2014, other than the updates described below.
	Principles of Consolidation and Basis of Presentation
	The consolidated financial statements include the accounts of the Company, consolidated joint venture arrangements and its subsidiaries. The portions of the consolidated joint venture arrangements not owned by the Company are presented as non-controlling interests. In addition, as described in Note 1 — Organization, certain affiliates and non-affiliated third parties have been issued OP Units. Holders of OP Units are considered to be non-controlling interest holders in the OP and their ownership interest is reflected as equity in the consolidated balance sheets. In addition, a portion of the earnings and losses of the OP are allocated to non-controlling interest holders based on their respective ownership percentages. Upon conversion of OP Units to common stock, any difference between the fair value of common shares issued and the carrying value of the OP Units converted is recorded as a component of equity. As of September 30, 2014 and December 31, 2013, there were 24,690,496 and 9,591,173 OP Units outstanding, respectively. In addition, as discussed in Note 3 —Mergers and Acquisitions, the historical information of ARCT III and ARCT IV has been presented as if the mergers had occurred as of the beginning of the earliest period presented.
	The Company evaluates its relationships and investments to determine if it has variable interests. A variable interest is an investment or other interest that will absorb portions of an entity’s expected losses or receive portions of the entity’s expected residual returns. The Company’s evaluation includes consideration of the qualitative and quantitative significance of fees it earns from certain of its relationships and investments. If the Company determines that it has a variable interest in an entity, it evaluates whether such interest is in a variable interest entity (“VIE”). A VIE is broadly defined as an entity where either (1) the equity investors as a group, if any, lack the power through voting or similar rights to direct the activities of an entity that most significantly impact the entity’s economic performance or (2) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support.
	A variable interest holder is considered to be the primary beneficiary of a VIE if it has the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and has the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to the VIE. The Company qualitatively assesses whether it is (or is not) the primary beneficiary of a VIE. Consideration of various factors include, but are not limited to, the Company’s ability to direct the activities that most significantly impact the entity’s economic performance, its form of ownership interest, its representation on the entity’s governing body, the size and seniority of its investment, its ability and the rights of other investors to participate in policy making decisions and to replace the manager of and/or liquidate the entity. The Company consolidates any VIEs when it is determined to be the primary beneficiary of the VIE’s operations and the difference between consolidating the VIE and accounting for it on the equity method would be material to the Company’s financial statements.
	The Company continually evaluates the need to consolidate joint ventures and the managed investment programs based on standards set forth in GAAP as described above.
	Investment in Unconsolidated Entities
	Investment in Unconsolidated Joint Ventures
	Investment in unconsolidated joint ventures as of September 30, 2014 consisted of the Company’s interest in six joint ventures that owned six properties (the “Unconsolidated Joint Ventures”). As of September 30, 2014, the Company owned aggregate equity investments of $96.4 million in the Unconsolidated Joint Ventures. The Company accounts for the Unconsolidated Joint Ventures using the equity method of accounting as the Company has the ability to exercise significant influence, but not control, over operating and financial policies of these investments. The equity method of accounting requires the investment to be initially recorded at cost and subsequently adjusted for the Company’s share of equity in the joint ventures’ earnings and distributions. The Company records its proportionate share of net income from the Unconsolidated Joint Ventures within the Other income, net line item in the consolidated statement of operations. During the three and nine months ended September 30, 2014, the Company recognized $0.2 million and $1.6 million, respectively, of net income from the Unconsolidated Joint Ventures. The Company did not recognize any net income from the Unconsolidated Joint Ventures during the three and nine months ended September 30, 2013.
	Investment in Managed REITs
	As of September 30, 2014, the Company owned aggregate equity investments of $4.4 million in the following publicly registered, non-traded REITs: Cole Credit Property Trust IV, Inc. (“CCPT IV”); Cole Corporate Income Trust, Inc. (“CCIT”); Cole Real Estate Income Strategy (Daily NAV), Inc. (“INAV”); Cole Office & Industrial REIT (CCIT II), Inc. (“CCIT II”); and Cole Credit Property Trust V, Inc. (“CCPT V,” and collectively with CCPT IV, CCIT, INAV and CCIT II, the “Managed REITs”). Prior to the CCPT Acquisition Date, CCPT was a Managed REIT and accounted for using the equity method. As of the CCPT Acquisition Date, the Company had an approximate $5,000 equity investment in CCPT. The Company accounts for these investments using the equity method of accounting which requires the investment to be initially recorded at cost and subsequently adjusted for the Company’s share of equity in the respective Managed REIT’s earnings and distributions. The Company records its proportionate share of net income from the Managed REITs within the Other income, net line item in the consolidated statement of operations. During the three and nine months ended September 30, 2014, the Company recognized $0.4 million of net income and $1.4 million of net loss, respectively, from the Managed REITs. The Company did not recognize any net income from the Managed REITs during the three and nine months ended September 30, 2013.
	Leasehold Improvements and Property and Equipment
	The Company leases its office facilities under operating leases. Leasehold improvements related to these are recorded at cost less accumulated amortization. Leasehold improvements are amortized over the lesser of the estimated useful life or remaining lease term.
	Property and equipment, which primarily include office furniture, fixtures and equipment and computer hardware and software, are stated at cost less accumulated depreciation. Property and equipment are depreciated on a straight-line method over the estimated useful lives of the assets, which range from five to seven years. The Company reassesses the useful lives of its property and equipment and adjusts the future monthly depreciation expense based on the new useful life, as applicable. If the Company disposes of an asset, the asset and related accumulated depreciation are written off upon disposal.
	Impairments
	Investment in Unconsolidated Entities
	The Company is required to determine whether an event or change in circumstances has occurred that may have a significant adverse effect on the fair value of any of its investment in the unconsolidated entities. If an event or change in circumstance has occurred, the Company is required to evaluate its investment in the unconsolidated entity for potential impairment and determine if the carrying amount of its investment exceeds its fair value. An impairment charge is recorded when an impairment is deemed to be other-than-temporary. To determine whether an impairment is other-than-temporary, the Company considers whether it has the ability and intent to hold the investment until the carrying amount is fully recovered. The evaluation of an investment in an unconsolidated entity for potential impairment requires the Company’s management to exercise significant judgment and to make certain assumptions. The use of different judgments and assumptions could result in different conclusions. No impairments of unconsolidated entities were identified during the nine months ended September 30, 2014.
	Leasehold Improvements and Property and Equipment
	Leasehold improvements and property and equipment are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. If this review indicates that the carrying amount of the asset is not recoverable, the Company records an impairment loss, measured at fair value by estimated discounted cash flows or market appraisals. The evaluation of an investment in a property for potential impairment requires the Company’s management to exercise significant judgment and to make certain assumptions. The use of different judgments and assumptions could result in different conclusions. The Company identified properties during the three and nine months ended September 30, 2014 and 2013 with impairment indicators for which the undiscounted future cash flows expected as a result of the use and eventual disposition of the real estate and related assets was less than the carrying amount of each respective properties, as discussed in Note 11 — Fair Value of Financial Instruments.
	In addition to the properties discussed in Note 11 — Fair Value of Financial Instruments, as of September 30, 2014, the Company noted potential impairment indicators at certain properties with an aggregate carrying value of $145.5 million. However, the Company’s estimate of undiscounted cash flows indicated that such carrying amounts were expected to be recovered as of September 30, 2014. Nonetheless, it is reasonably possible that the estimate of undiscounted cash flows may change in the near term, which will result in the need to record an impairment loss to reduce such assets to fair value. Any such impairment losses may have a material impact on the Company’s assets and stockholder’s equity, operating and net loss and comprehensive loss. The evaluation of properties for potential impairment requires the Company’s management to exercise significant judgment and to make certain assumptions. The use of different judgments and assumptions could result in different conclusions.
	Goodwill
	In the case of a business combination, after identifying all tangible and intangible assets and liabilities, the excess consideration paid over the fair value of the assets and liabilities acquired and assumed, respectively, represents goodwill. Goodwill that arose as a result of the Company’s mergers and acquisitions was recorded in the Company’s consolidated financial statements.
	In the event the Company disposes of a property that constitutes a business under U.S. GAAP from a reporting unit with goodwill, the Company will allocate a portion of the reporting unit’s goodwill to that business in determining the gain or loss on the disposal of the business. The amount of goodwill allocated to the business will be based on the relative fair value of the business to the fair value of the reporting unit. The REI segment and Cole Capital each comprise one reporting unit.
	The Company will evaluate goodwill for impairment annually or more frequently when an event occurs or circumstances change that indicate the carrying value, by reporting unit, may not be recoverable. The Company’s annual testing date is during the fourth quarter. The Company will test goodwill for impairment by first comparing the book value of net assets to the fair value of each reporting unit. If the fair value is determined to be less than the book value or if qualitative factors indicate that it is more likely than not that goodwill is impaired, a second step is performed to compute the amount of impairment as the difference between the estimated fair value of goodwill and the carrying value. The Company will estimate the fair value of the reporting units using discounted cash flows and relevant competitor multiples. The evaluation of goodwill for potential impairment requires the Company’s management to exercise significant judgment and to make certain assumptions. The use of different judgments and assumptions could result in different conclusions. In conjunction with the disposition of the Multi-Tenant Portfolio, as defined in Note 22 — Property Dispositions, the Company evaluated the remaining portion of goodwill assigned to the REI segment for impairment. The fair value of the REI segment was determined to be greater than the book value of its net assets. As such, no goodwill impairment was recorded during the nine months ended September 30, 2014.
	Subsequent to September 30, 2014, the Company noted potential impairment indicators of goodwill such that it is reasonably possible that the estimate of the fair value of each reporting unit may change in the near term, which will result in the need to record an impairment loss to reduce goodwill to fair value. Any such impairment losses may have a material impact on the Company’s assets and stockholder’s equity, operating and net loss and comprehensive loss.
	The following summarizes the Company’s goodwill activity during the nine months ended September 30, 2014 by segment (in thousands):
			REI Segment			Cole Capital			Consolidated
	Balance as of January 1, 2014		$	92,789		$	—		$	92,789
	Cole Merger (1)			1,654,085			558,835			2,212,920
	Goodwill allocated to dispositions (2)			(209,259	)		—			(209,259	)
	Balance as of September 30, 2014		$	1,537,615		$	558,835		$	2,096,450
	-1	Goodwill recognized from the Cole Merger was assigned to the REI segment and Cole Capital based on the excess consideration paid over the fair value of the assets and liabilities acquired and assumed in each segment. Refer to Note 5 — Acquisitions of CapLease, Cole and CCPT for further discussion.
	-2	Goodwill allocated to the cost basis of properties sold or classified as held for sale is included in loss on held for sale assets and disposition of properties, net, in the consolidated statement of operations.
	Program Development Costs
	The Company pays for organization, registration and offering expenses associated with the sale of common stock of the Managed REITs. The reimbursement of these expenses by the Managed REITs is limited to a certain percentage of the proceeds raised from their offerings, in accordance with their respective advisory agreements and charters. Such expenses paid by the Company on behalf of the Managed REITs in excess of these limits that are expected to be collected are recorded as program development costs. The Company assesses the collectability of the program development costs, considering the offering period and historical and forecasted sales of shares under the Managed REITs’ respective offerings and reserves for any balances considered not collectible. No reserves were recorded as of September 30, 2014, as the Company expects to be reimbursed for all of the program development costs by the Managed REITs as additional proceeds from their respective offerings are raised. Program development costs are included in deferred costs and other assets, net in the accompanying consolidated balance sheets.
	Acquisition Related Expenses and Merger and Other Non-routine Transaction Related Expenses
	All direct costs incurred as a result of a business combination are classified as acquisition costs or merger and other non-routine transaction costs and expensed as incurred. In addition, indirect costs, such as internal salaries, that are tracked and documented in a manner that clearly indicate that the activities driving the cost directly relate to activities necessary to complete, or effect, a business combination are classified as acquisition related expenses. Similar costs incurred in relation to mergers with entities under common control (which are not accounted for as acquisitions) are included in the caption “merger and other non-routine transactions.” Acquisition related expenses include legal and other transaction related costs incurred in connection with self-originated acquisitions including purchases of portfolios. Other non-routine transaction costs are also presented within the line item merger and other non-routine transactions in the consolidated statements of operations.
	Merger and other non-routine transaction related expenses include the following costs (amounts in thousands):
			Three Months Ended September 30,						Nine Months Ended September 30,
			2014			2013			2014			2013
						(As Corrected)						(As Corrected)

	Due from Affiliates
	The Company receives or may be entitled to receive compensation and reimbursement for services primarily relating to the Managed REITs’ offerings and the investment, management, financing and disposition of their respective assets. Refer to Note 20 — Related Party Transactions and Arrangements for further explanation.
	Reportable Segments
	The Company has concluded that it has two reportable segments as it has organized its operations into two segments for management and internal financial reporting purposes, REI and Cole Capital. The identification and aggregation of reportable segments requires the Company’s management to exercise certain judgments. Refer to Note 6 — Segment Reporting for further information.
	Revenue Recognition - Cole Capital
	Revenue consists of securities sales commissions and dealer manager fees, real estate acquisition fees, property management fees, advisory fees, asset management fees and performance fees for services relating to the Managed REITs’ offerings and the investment and management of their respective assets, in accordance with the respective advisory and dealer manager agreements. The Company records revenue related to acquisition fees, securities sales commissions and dealer manager fees upon completion of a transaction and advisory, asset and property management fees as services are performed. The Company is also reimbursed for certain costs incurred in providing these services. Securities sales commission and dealer manager reimbursements are recorded as revenue as the expenses are incurred. Other reimbursements are recorded as revenue when reimbursements are reasonably assured.
Income Taxes
ARCP currently qualifies and has elected to be taxed as a REIT for federal income tax purposes under Sections 856 through 860 of the Internal Revenue Code. As a REIT, except as discussed below, ARCP generally is not subject to federal income tax on taxable income that it distributes to its stockholders so long as it distributes at least 90% of its annual taxable income (computed without regard to the dividends paid deduction and excluding net capital gains). REITs are subject to a number of other organizational and operational requirements. Even if ARCP maintains its qualification for taxation as a REIT, it may be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed income.
The Operating Partnership is classified as a partnership for federal income tax purposes. As a partnership, the Operating Partnership is not a taxable entity for federal income tax purposes. Instead, each partner in the Operating Partnership is required to take into account its allocable share of the Operating Partnership’s income, gains, losses, deductions, and credits for each taxable year. However, the Operating Partnership may be subject to certain state and local taxes on its income and property.
As of September 30, 2014, the Operating Partnership, ARCP, ARCT III and ARCT IV had no material uncertain income tax positions. The tax years subsequent to and including the fiscal year ended December 31, 2010 remain open to examination by the major taxing jurisdictions to which the Operating Partnership, ARCP, ARCT III and ARCT IV are subject.
Under the LPA, the Operating Partnership is to conduct business in such a manner as to permit ARCP at all times to qualify as a REIT.
The Company conducts substantially all of its Cole Capital business operations through a TRS. A TRS is a subsidiary of a REIT that is subject to corporate federal, state and local income taxes, as applicable. The Company’s use of a TRS enables it to engage in certain business activities while complying with the REIT qualification requirements and to retain any income generated by these businesses for reinvestment without the requirement to distribute those earnings. The Company conducts all of its business in the United States, and as a result, it files income tax returns in the U.S. federal jurisdiction and various state and local jurisdictions. Certain of The Company’s inter-company transactions that have been eliminated in consolidation for financial accounting purposes are also subject to taxation.
The Company provides for income taxes in accordance with current authoritative accounting and tax guidance. The tax expense or benefit related to significant, unusual or extraordinary items is recognized in the quarter in which those items occur. In addition, the effect of changes in enacted tax laws, rates or tax status is recognized in the quarter in which the change occurs. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained or the tax environment changes.
In conjunction with the acquisition of the Red Lobster Portfolio, the Company entered into a reverse section 1031 like-kind exchange agreement with a third party intermediary. The exchange agreement is for a maximum of 180 days and allows the Company, for tax purposes, to defer gains on the sale of other properties sold within this period. Until the earlier of termination of the exchange agreements or 180 days after the first acquisition date, the third party intermediary is the legal owner of each property, although the Company controls the activities that most significantly impact each property and retains all of the economic benefits and risks associated with each property. Each property is held by the third party intermediary in a variable interest entity for which the Company is the primary beneficiary. Accordingly, the Company consolidates these properties and their operations even during the period they are held by the third party intermediary. As of September 30, 2014, 541 Red Lobster properties acquired in July and September of 2014 were held by the third party intermediary. The Company has consolidated each of these properties since the date of acquisition.
Repurchase Agreements
In certain circumstances, the Company may obtain financing through a repurchase agreement. The Company evaluates the initial transfer of a financial instrument and the related repurchase agreement for sale accounting treatment. In instances where the Company maintains effective control over the transferred securities, the Company accounts for the transaction as a secured borrowing, and accordingly, both the securities and related repurchase agreement payable are recorded separately in the accompanying consolidated balance sheets in investment securities, at fair value and other debt, net, respectively. In instances where the Company does not maintain effective control over the transferred securities, the Company accounts for the transaction as a sale of securities for proceeds consisting of cash and a forward purchase contract.
Recent Accounting Pronouncements
In April 2014, the U.S. Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update, 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 (“ASU 2014-08”), which amends the reporting requirements for discontinued operations by updating the definition of a discontinued operation to be a component of an entity that represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results, resulting in fewer disposals that qualify for discontinued operations reporting yet the pronouncement also requires expanded disclosures for discontinued operations. The Company adopted ASU 2014-08 effective January 1, 2014. Beginning with the first quarter of 2014, the results of operations for all properties sold and properties classified as held for sale that do not meet the criteria to qualify as a discontinued operation and were not previously reported in discontinued operations in the Amended 10-K for the year ended December 31, 2013 are presented within income from continuing operations on the accompanying consolidated statements of income.
In May 2014, FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which supersedes the revenue recognition requirements in Revenue Recognition (Topic 605), and requires an entity to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and is to be applied retrospectively, with early application not permitted. The Company is currently evaluating the impact of the new standard on its financial statements.
In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”), which requires management to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. ASU 2014-15 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, with early application permitted. The Company does not believe ASU 2014-15, when effective, will have a material impact on the Company’s consolidated unaudited financial statements because the Company currently does not have any conditions that give rise to substantial doubt about its ability to continue as a going concern.
In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis (“ASU 2015-02”), which eliminates the deferral of FAS 167 and makes changes to both the variable interest model and the voting model. These changes will require re-evaluation of certain entities for consolidation and will require the Company to revise its documentation regarding the consolidation or deconsolidation of such entities. ASU 2015-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, and is to be applied retrospectively, with early adoption permitted. The Company is currently evaluating the impact of the new standard on its financial statements.

Business Combinations [Abstract]
Acquisitions of CapLease, Cole and CCPT	Note 5 — Acquisitions of CapLease, Cole and CCPT
	CapLease Acquisition
	On November 5, 2013 (the “CapLease Acquisition Date”), the Company completed the CapLease Merger, an acquisition of a real estate investment trust that primarily owned and managed a diversified portfolio of single tenant commercial real estate properties subject to long-term leases, the majority of which were net leases, to high credit quality tenants, by acquiring 100% of the outstanding common stock and voting interests of CapLease. The acquisition was accounted for using the acquisition method of accounting in accordance with ASC 805, Business Combinations. The Company’s consolidated financial statements include the results of operations of CapLease subsequent to the CapLease Acquisition Date.
	The purchase price includes a cash payment of $920.7 million, which was funded by the Company through additional borrowings under its revolving credit facility and the credit facility assumed from CapLease. See Note 13 — Other Debt and Note 14 — Credit Facilities.
	The purchase price allocation for the CapLease Merger is considered preliminary, and additional adjustments may be recorded during the measurement period in accordance with U.S. GAAP. The purchase price allocation will be finalized as the Company receives additional information relevant to the acquisition, including a final valuation of the assets purchased and liabilities assumed.
	The preliminary purchase price for the acquisition was allocated to assets acquired and liabilities assumed based on their estimated fair value. The following table summarizes the revised estimated fair values of the assets acquired and liabilities assumed at the CapLease Acquisition Date (in thousands):

	Management is in the process of further evaluating the purchase price accounting. The fair value of real estate investments and below-market leases have been estimated by the Company with the assistance of third-party valuation firms. Based on a preliminary analysis received to-date, the estimated fair value of these assets and liabilities total $2.0 billion and $57.1 million, respectively. The recorded values represent the estimated fair values related to such assets and liabilities. Upon completion of the analysis, including a review of the appraisals and assessment of current market rates, changes to the estimated fair values may result. Such post-closing adjustments are customary in nature in accordance with ASC 805, Business Combinations.
	The ascribed value of the non-controlling interest has been estimated based on the fair value at the acquisition date of the percentage ownership of The Woodlands, Texas development activity not held by the Company. See Note 7 — Real Estate Investments for further information on this development project.
	The fair value of the remaining CapLease assets and liabilities have been calculated in accordance with the Company’s policy on purchase price allocation, as disclosed in the Amended 10-K for the year ended December 31, 2013.
	Goodwill of approximately $92.8 million has been preliminarily assigned to the REI segment. The goodwill recognized is attributed to the enhancement of the Company’s year-round rental revenue stream, expected synergies and the assembled work force at CapLease.
	The pro forma consolidated statements of operations in Note 7 — Real Estate Investments are presented as if CapLease had been included in the consolidated results of the Company for the nine months ended September 30, 2014 and 2013.
	Cole Acquisition
	On February 7, 2014, the Company completed its acquisition of Cole, as discussed in Note 3 — Mergers and Acquisitions. The Company accounted for the Cole Merger as a business combination under the acquisition method of accounting. Therefore, the Company’s consolidated financial statements include the results of operations of Cole subsequent to the Cole Acquisition Date.
	Fair Value of Consideration Transferred
	The Company is in the process of gathering certain additional information in order to finalize its assessment of the fair value of the consideration transferred; thus, the fair values of currently recorded assets and liabilities are subject to change. The estimated fair value of the consideration transferred at the Cole Acquisition Date totaled approximately $7.5 billion and consisted of the following (in thousands):
			As of Cole Acquisition
			Date (Preliminary)
	Estimated Fair Value of Consideration Transferred:
	Cash		$	181,775
	Common stock			7,285,868
	Total consideration transferred		$	7,467,643
	The fair value of the 520.8 million shares of ARCP’s common stock issued, excluding those common shares transferred to former Cole executives, was determined based on the closing market price of ARCP’s common stock on the Cole Acquisition Date. In accordance with the LPA, the Operating Partnership issued a corresponding number of General Partner OP Units to ARCP when shares of ARCP’s common stock were issued to former stockholders of Cole.
	Allocation of Consideration
	The consideration transferred pursuant to the Cole Merger Agreement was allocated to the assets acquired and liabilities assumed for the REI segment and Cole Capital, based upon their preliminary estimated fair values as of the Cole Acquisition Date. The Company is in the process of gathering certain additional information in order to finalize its assessment of the fair value of certain intangible assets; thus, the provisional measurements of intangible assets and goodwill are subject to change. Such post-closing adjustments are customary in nature in accordance with ASC 805, Business Combinations. The measurement periods recorded for the period from the Cole Acquisition Date to September 30, 2014 are presented consolidated and by segments in the tables below.

The fair value of real estate investments, including acquired lease intangibles, and below-market lease liabilities allocated to the REI segment have been estimated by the Company with the assistance of a third party valuation firm. Based on a preliminary analysis received to date, the estimated fair value of these assets and liabilities total $9.0 billion and $212.4 million, respectively. The recorded values represent the estimated fair values related to such assets and liabilities. Upon completion of the analysis, including a review of the appraisals and assessment of current market rates, changes to the estimated fair values may result.
The intangible assets acquired primarily consist of management and advisory contracts that the Company has with the Managed REITs and are subject to an estimated useful life of approximately four years. The Company recorded $62.3 million of amortization expense for the period from the Cole Acquisition Date to September 30, 2014. The estimated amortization expense for the remainder of the year ending December 31, 2014 is $24.3 million. The estimated amortization expense for each of the years ending December 31, 2015, 2016 and 2017 is $96.3 million and the estimated amortization expense for the year ending December 31, 2018 is $9.8 million.
Subsequent to September 30, 2014, the Company noted potential impairment indicators of intangible assets acquired in the Cole Merger such that it is reasonably possible that the estimate of the fair value of such intangible assets may change in the near term, which will result in the need to record an impairment loss to reduce the intangible assets to fair value. Any such impairment losses may have a material impact on the Company’s assets and stockholder’s equity, operating and net loss and comprehensive loss.
Goodwill of approximately $1.7 billion has been preliminarily assigned to the REI segment. The goodwill recognized is attributed to the enhancement of the Company’s year-round rental revenue stream, realized and expected synergies, the impact of the merger on lowering the Company’s cost of capital, as well as the benefits of critical mass, improved portfolio diversification and enhanced access to capital markets. Goodwill of approximately $558.8 million has been preliminarily assigned to Cole Capital. The goodwill is primarily supported by management’s belief that Cole Capital brings an established management platform with numerous strategic benefits including growth from new income streams and the ability to offer new products. None of the goodwill is expected to be deductible for income tax purposes.
The fair value of the remaining Cole assets and liabilities have been calculated in accordance with the Company’s policy on purchase price allocation, as disclosed in the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2013.
The amounts of revenue and net income related to Cole property acquisitions and Cole Capital included in the accompanying consolidated statements of operations from the Cole Acquisition Date to the period ended September 30, 2014 was $625.8 million and $68.9 million respectively.
The pro forma consolidated statements of operations in Note 7 — Real Estate Investments are presented as if Cole had been included in the consolidated results of the Company for the entire periods ended September 30, 2014 and 2013.
CCPT Acquisition
On May 19, 2014, the Company completed its acquisition of CCPT, as discussed in Note 3 — Mergers and Acquisitions. The Company accounted for the CCPT Merger as a business combination under the acquisition method of accounting. Therefore, the Company’s consolidated financial statements include the results of operations of CCPT subsequent to the CCPT Acquisition Date.
Fair Value of Consideration Transferred
The Company is in the process of gathering certain additional information in order to finalize its assessment of the fair value of the consideration transferred; thus, the fair values of currently recorded assets and liabilities are subject to change. The estimated fair value of the consideration transferred at the CCPT Acquisition Date totaled approximately $73.2 million, which was paid in cash. The acquisition was funded by the Company through additional borrowings under its revolving credit facility.
Allocation of Consideration
The consideration transferred pursuant to the CCPT Merger Agreement was allocated to the assets acquired and liabilities assumed based upon their preliminary estimated fair values as of the CCPT Acquisition Date. The Company is in the process of gathering certain additional information in order to finalize its assessment of the fair value of certain intangible assets; thus, the provisional measurements of intangible assets and goodwill are subject to change. Such post-closing adjustments are customary in nature in accordance with ASC 805, Business Combinations. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed by segment at the CCPT Acquisition Date (in thousands):

	The Company operates under two segments, REI and Cole Capital.
	REI – Through its REI segment, the Company acquires, owns and operates primarily single-tenant, freestanding commercial real estate properties primarily subject to net leases with high credit quality tenants. As of September 30, 2014, the Company owned 4,714 properties comprising 113.8 million square feet of single- and multi-tenant retail and commercial space located in 49 states and Canada, which include properties owned through consolidated joint ventures. The rentable space at these properties was 99.2% leased with a weighted average remaining lease term of 11.50 years. In addition, as of September 30, 2014, the Company owned 10 commercial mortgage-backed securities (“CMBS”), 14 loans held for investment and, through the Unconsolidated Joint Ventures, had interests in six properties comprising 1.6 million rentable square feet of commercial and retail space.
	Cole Capital – Cole Capital is contractually responsible for managing the Managed REITs’ affairs on a day-to-day basis, identifying and making acquisitions and investments on the Managed REITs’ behalf and recommending to each of the Managed REIT’s respective board of directors an approach for providing investors with liquidity. Cole Capital serves as the dealer manager and distributes shares of common stock for certain Managed REITs and advises them regarding offerings, manages relationships with participating broker-dealers and financial advisors and provides assistance in connection with compliance matters relating to the offerings. Cole Capital receives compensation and reimbursement for services relating to the Managed REITs’ offerings and the investment, management, financing and disposition of their respective assets, as applicable. Cole Capital also develops new REIT offerings, including obtaining regulatory approvals from the SEC, the Financial Industry Regulatory Authority, Inc. (“FINRA”) and various blue sky jurisdictions for such offerings.
	On September 30, 2014, the Company entered into a definitive equity purchase agreement (the “Purchase Agreement”), to sell Cole Capital to RCAP, and, in conjunction with the sale agreement, entered into sub-advisory agreements to provide acquisition and property management services to Cole Capital subsequent to the closing of the transaction. These agreements were subsequently terminated by RCAP on November 3, 2014 as a result of the Audit Committee investigation into the Company. On December 4, 2014, a settlement agreement was reached as discussed within Note 24 — Subsequent Events.

During the nine months ended September 30, 2014, the Company completed 4 development projects.
	Prior to the CapLease Acquisition Date, CapLease entered into an agreement with a major Texas-based developer to develop a 150,000 square foot speculative office building in The Woodlands, Texas, adjacent to and part of the same development as an existing office building owned by CapLease since 2012. Costs of the project, which are budgeted to be $34.0 million, are scheduled to be funded by equity contributions from the Company and its developer partner, and $17.0 million of advances during the construction period under a development loan entered into with Amegy Bank. All equity contributions are scheduled to be borne as follows: the Company, 90%; and the developer, 10%; except for cost overruns, which will be borne 50% by each. Because the Company has a controlling financial interest in the investment, the Company consolidates the investment for financial accounting purposes. The Company has an option to purchase, and the developer the option to sell to the Company, in each case at fair market value, the developer’s interest in the project upon (i) substantial completion of the project and (ii) leases being entered into for 95% of the square footage of the project. Construction activity and funding of the project commenced during the quarter ended September 30, 2013 and was expected to be completed during the second half of 2014. As of September 30, 2014, the Company had a total investment of $23.8 million, including capitalized interest of $69,000, and estimated remaining investment of $10.2 million related to the development project.
	Tenant Concentration
	As of September 30, 2014, there was one tenant exceeding 10% of consolidated annualized rental income. As of September 30, 2013, there were no tenants exceeding 10% of consolidated annualized rental income. Annualized rental income for net leases is rental income as of the period reported, which includes the effect of tenant concessions such as free rent, as applicable.
	Geographic Concentration
	As of September 30, 2014, properties located in Texas represented 12.6% of consolidated annualized rental income determined on a straight-line basis. There were no geographic concentrations exceeding 10% of consolidated annualized rental income at September 30, 2013.

Loans Held for Investment	Note 9 — Loans Held for Investment
	During the nine months ended September 30, 2014, in connection with the Cole Merger, the Company acquired two mortgage notes receivable, each of which is secured by an office building. The mortgage notes had a fair value of $72.3 million as of the Cole Acquisition Date. As of December 31, 2013, the Company owned 12 loans held for investment, which were acquired in connection with the CapLease Merger and consist predominantly of mortgage loans on properties subject to leases to investment grade tenants. The loans had a fair value of $26.5 million at the CapLease Merger Date. At September 30, 2014, the Company owned 14 loans held for investment, which had a carrying value of $97.0 million and carried interest rates ranging from 5.28% to 7.24%. As of December 31, 2013, the two loans held for investment had a carrying value of $26.3 million and carried interest rates ranging from 5.28% to 7.24%. The fair value adjustment is being amortized to interest expense in the consolidated statements of operations over the term of the loan, using the effective interest method.
	The Company’s loan portfolio is comprised primarily of fully amortizing or nearly fully amortizing first mortgage loans on commercial real estate leased to a single tenant. Therefore, the Company’s monitoring of the credit quality of its loans held for investment is focused primarily on an analysis of the tenant, including review of tenant credit ratings (including changes in ratings) and other measures of tenant credit quality, trends in the tenant’s industry and general economic conditions and an analysis of measures of collateral coverage, such as an estimate of the loan’s loan-to-value (“LTV”) ratio (principal amount outstanding divided by estimated value of the property) and its remaining term until maturity. As of September 30, 2014 and December 31, 2013, the Company had no reserve for loan loss.

Fair_Value_of_Financial_Instru

Fair Value of Financial Instruments	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 11 — Fair Value of Financial Instruments
	The Company determines fair value based on quoted prices when available or through the use of alternative approaches, such as discounting the expected cash flows using market interest rates commensurate with the credit quality and duration of the investment. The guidance defines three levels of inputs that may be used to measure fair value:
	Level 1 — Quoted prices in active markets for identical assets and liabilities that the reporting entity has the ability to access at the measurement date.
	Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset and liability or can be corroborated with observable market data for substantially the entire contractual term of the asset or liability.
	Level 3 — Unobservable inputs that reflect the entity’s own assumptions about the assumptions that market participants would use in the pricing of the asset or liability and are consequently not based on market activity, but rather through particular valuation techniques.
	The determination of where an asset or liability falls in the hierarchy requires significant judgment and considers factors specific to the asset or liability. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company evaluates its hierarchy disclosures each quarter and depending on various factors, it is possible that an asset or liability may be classified differently from quarter to quarter. However, the Company expects that changes in classifications between levels will be infrequent.
	Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with those derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. However, as of September 30, 2014, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of the Company’s derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.
	During the three and nine months ended September 30, 2014, real estate assets with a carrying amount of $5.1 million related to five properties and real estate assets with a carrying amount of $8.2 million related to nine properties, respectively, were deemed to be impaired and their carrying amounts were reduced to their estimated fair values, resulting in impairment charges of $2.3 million and $3.9 million, respectively, which are included in impairment of real estate on the consolidated statements of operations for the three and nine months ended September 30, 2014. During the three and nine months ended September 30, 2013, real estate assets with a carrying amount of $2.6 million related to one property were deemed to be impaired and their carrying amounts were reduced to their estimated fair values, resulting in impairment charges of $2.1 million, which is included in impairment of real estate on the consolidated statements of operations for the three and nine months ended September 30, 2013. During the year ended December 31, 2013, real estate assets with carrying amounts of $4.5 million related to two properties were deemed to be impaired and their carrying amounts were reduced to their estimated fair value, resulting in an impairment charge of $3.3 million.
	The Company’s estimated fair values of its real estate assets were primarily based upon an income approach utilizing a present value technique to discount the expected cash flows using market participant assumptions for market rent and terminal values, which are considered to be Level 3 inputs, or based upon recent comparable sales transactions, which are considered to be Level 2 inputs. The aggregate fair value of impaired real estate assets as of September 30, 2014 and December 31, 2013 was $2.8 million, and $1.2 million, respectively.
	The following tables present information about the Company’s assets and liabilities (including derivatives that are presented net) measured at fair value on a recurring basis as of September 30, 2014 and December 31, 2013, aggregated by the level in the fair value hierarchy within which those instruments fall (in thousands):

	CMBS — The fair values of the Company’s CMBS are valued using broker quotations, collateral values, subordination levels and liquidity of the individual securities.
	Derivatives — The valuation of derivative instruments is determined using a discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, as well as observable market-based inputs, including interest rate curves and implied volatilities. In addition, credit valuation adjustments are incorporated into the fair values to account for the Company’s potential nonperformance risk and the performance risk of the counterparties.
	Series D Preferred Stock embedded derivative — The valuation of this derivative instrument was determined using a binomial option pricing model. Key inputs in the model include the expected term, risk-free interest rate, volatility and dividend yield.
	The fair value of short-term financial instruments such as cash and cash equivalents, restricted cash, due to affiliates and accounts payable approximate their carrying value on the accompanying consolidated balance sheets due to their short-term nature and are classified as Level 1 under the fair value hierarchy.
	A review of the fair value hierarchy classification is conducted on a quarterly basis. Changes in the type of inputs may result in a reclassification for certain assets. There were no transfers between Level 1 and Level 2 or Level 3 of the fair value hierarchy during the nine months ended September 30, 2014.
	The following is a reconciliation of the changes in instruments with Level 3 inputs in the fair value hierarchy for the nine months ended September 30, 2014 (in thousands):

Loans held for investment — The fair value of the Company’s fixed-rate loan portfolio is estimated with a discounted cash flow analysis, utilizing scheduled cash flows and discount rates estimated by management to approximate those that a willing buyer and seller might use.
Credit facilities — Management believes that the stated interest rates (which float based on short-term interest rates) approximate market rates. As such, the fair values of these obligations are estimated to be equal to the outstanding principal amounts.
Convertible notes, mortgage notes payable and secured term loan — The fair value of mortgages payable on real estate investments and the secured term loan is estimated by an independent third party using a discounted cash flow analysis, based on management’s estimates of market interest rates.
Trust preferred notes — The fair value of the Company’s other long-term debt is estimated using a discounted cash flow analysis, based on management’s estimates of market interest rates.

	During the three and nine months ended September 30, 2014, the Company paid off $173.3 million and $1.0 billion, respectively, of mortgage notes payable, including notes that were subject to interest rate swap agreements. In connection with the debt repayments, the Company paid prepayment fees totaling $3.0 million and $35.9 million for the three and nine months ended September 30, 2014, respectively, which are included in Extinguishment of debt, net in the accompanying consolidated statements of operations. In addition, the Company paid $0.1 million and $10.2 million during the three and nine months ended September 30, 2014 for the settlement of interest rate swaps that were associated with certain mortgage notes, which approximated the fair value of the interest rate swaps. The Company wrote off the deferred financing costs and premiums and discounts associated with these mortgages, which resulted in a gain of $1.9 million and $18.9 million during the three and nine months ended September 30, 2014, respectively, which is included in Extinguishment of debt, net in the accompanying consolidated statements of operations.

The Notes are guaranteed by the Company. The OP may redeem all or a part of any series of the Notes at any time at its option at the redemption prices set forth in the indenture governing the Notes, plus accrued and unpaid interest on the principal amount of the Notes of such series being redeemed to, but excluding, the applicable redemption date. With respect to the 2019 Notes and the 2024 Notes, if such Notes are redeemed on or after January 6, 2019 with respect to the 2019 Notes, or November 6, 2023 with respect to the 2024 Notes, the redemption price will equal 100% of the principal amount of the Notes of the applicable series to be redeemed, plus accrued and unpaid interest on the amount being redeemed to, but excluding, the applicable redemption date. In conjunction with this corporate bond offering, aggregate discounts totaling $4.2 million were recorded. As of September 30, 2014, the unamortized net discount totaled $3.7 million.
	On September 12, 2014, the OP commenced an offer to exchange the 2017 Notes, 2019 Notes and 2024 Notes for new $1.3 billion aggregate principal amount of 2.00% senior notes due 2017 (the “Exchange 2017 Notes”), new $750.0 million aggregate principal amount of 3.00% senior notes due 2019 (the “Exchange 2019 Notes”) and new $500.0 million aggregate principal amount of 4.60% senior notes due 2024 (the “Exchange 2024 Notes,” and, together with the Exchange 2017 Notes and Exchange 2019 Notes, the “Exchange Notes”). The terms of the Exchange Notes are substantially similar to the terms of the Notes except that the Exchange Notes are registered under the Securities Act of 1933 and are freely transferable. The exchange offer closed on October 16, 2014, with 100% of the Notes exchanged for Exchanged Notes.
	Convertible Senior Note Offering
	Effective July 29, 2013, the Operating Partnership issued to the General Partner $300.0 million of the 3.0% Convertible Senior Notes due 2018 and issued an additional $10.0 million of such notes on August 1, 2013 (collectively, the “Original 2018 Notes”). Effective December 10, 2013, the Company issued an additional $287.5 million through a reopening of the Original 2018 Notes indenture agreement (the “Reopened 2018 Notes,” together with the Original 2018 Notes, the “2018 Notes”). The 2018 Notes mature on August 1, 2018. Such issuances were identical to ARCP’s registered issuances of the same amount of notes to various purchasers in a public offering. The fair value of the Original 2018 Notes and Reopened 2018 Notes was determined at issuance to be $299.6 million and $282.1 million, respectively, resulting in a debt discount of $10.4 million and $5.4 million, respectively, with an offset recorded for the General Partner to additional paid-in capital and for the Operating Partnership to partners’ equity, both representing the equity component of the notes for the conversion options. The discount is being amortized to interest expense over the expected lives of the 2018 Notes. As of September 30, 2014, the carrying value of the Original 2018 Notes and Reopened 2018 Notes was $302.1 million and $283.0 million, respectively. In connection with any permissible conversion election made by the holders of the identical convertible notes issued by ARCP, the General Partner may elect to convert the 2018 Notes into cash, General Partner OP Units or a combination thereof, in limited circumstances prior to February 1, 2018 and may convert the 2018 Notes at any time into such consideration on or after February 1, 2018. The initial conversion rate is 59.805 General Partner OP Units per $1,000 principal amount of 2018 Notes.
	Effective December 10, 2013, the Operating Partnership issued to the General Partner $402.5 million of 3.75% Convertible Senior Notes due 2020 (the “2020 Notes”). The 2020 Notes mature on December 15, 2020. Such issuance was identical to ARCP’s registered issuance of the same amount of notes to various purchasers in a public offering. The fair value of the 2020 Notes was determined at issuance to be $389.7 million, resulting in a debt discount of $12.8 million with an offset recorded recorded for the General Partner to additional paid-in capital and for the Operating Partnership to partners’ equity, both representing the equity component of the notes for the conversion options. The discount is being amortized to interest expense over the expected life of the 2020 Notes. As of September 30, 2014, the carrying value of the 2020 Notes was $391.2 million. In connection with any permissible conversion election made by the holders of the identical convertible notes issued by ARCP, the General Partner may elect to convert the 2020 Notes into cash, General OP Units or a combination thereof, in limited circumstances prior to June 15, 2020 and may convert the 2020 Notes at any time into such consideration on or after June 15, 2020. The initial conversion rate is 66.0262 General Partner OP Units per $1,000 principal amount of 2020 Notes.
	The remaining unamortized discount for the 2018 Notes and 2020 Notes totaled $23.7 million as of September 30, 2014.
	Secured Term Loan
	As part of the CapLease Merger, the Company assumed a secured term loan with KBC Bank, N.V. with a principal balance of $59.8 million and a fair value of $60.7 million at the CapLease Acquisition Date. The Company recorded a premium of $0.8 million upon the assumption of the term loan in Other debt, net on the consolidated balance sheet. The interest coupon on the loan is fixed at 5.81% annually until the loan matures in January 2018. The loan is non-recourse to the Company, subject to limited non-recourse exceptions. The secured term loan provides for monthly payments of both principal and interest. During the nine months ended September 30, 2014, the Company made principal payments of $10.2 million. The scheduled principal repayments subsequent to September 30, 2014 are $2.7 million for the period October 1, 2014 through December 31, 2014 and $11.9 million, $12.5 million, $7.7 million and $13.3 million for the years ended December 31, 2015, 2016, 2017 and 2018, respectively. The premium is being amortized to interest expense on the consolidated statements of operations over the life of the secured term loan. As of September 30, 2014, the unamortized premium is $0.6 million. As of September 30, 2014, the carrying value of the secured term loan was $48.6 million, which is included in other debt, net in the accompanying consolidated balance sheets.
	Amounts related to the secured term loan as of September 30, 2014 were as follows (in thousands):

Credit_Facilities

Credit Facilities	9 Months Ended
	Sep. 30, 2014
Text Block [Abstract]
Credit Facilities	Note 14 — Credit Facilities
	Senior Unsecured Credit Facility
	The General Partner, as guarantor, and the OP, as borrower, are parties to an unsecured credit facility with Wells Fargo, National Association, as administrative agent and other lenders party thereto (the “Credit Facility”).
	On June 30, 2014, the General Partner, as guarantor, and the OP, as borrower, entered into an amended and restated credit agreement (the “Agreement”), which increased the available borrowings, extended the term and decreased the interest rates associated with the Credit Facility, prior to the execution of the Agreement. The Company accepted commitments from 20 financial institutions totaling $4.7 billion for the Credit Facility. The Credit Facility is comprised of a $1.2 billion term loan facility (with a delayed draw component equal to $200.0 million), a $3.3 billion dollar-denominated revolving credit facility and a $250.0 million multi-currency revolving facility (all of which can be borrowed in dollars, at the Company’s discretion). The Credit Facility includes an accordion feature, which, if exercised in full, allows the Company to increase the aggregate commitments under the Credit Facility to $6.0 billion, subject to the receipt of such additional commitments and the satisfaction of certain customary conditions. Subsequent to the Agreement date, the Company accepted an additional $50.0 million commitment on the revolving credit facility from one of the original 20 financial institutions, bringing the total Credit Facility commitments to $4.7 billion.
	The revolving credit facility generally bears interest at an annual rate of LIBOR plus from 1.00% to 1.80% or Base Rate plus 0.00% to 0.80% (based upon ARCP’s then current credit rating). “Base Rate” is defined as the highest of the prime rate, the federal funds rate plus 0.50% or a floating rate based on one month LIBOR, determined on a daily basis. The term loan facility generally bears interest at an annual rate of LIBOR plus 1.15% to 2.05%, or Base Rate plus 0.15% to 1.05% (based upon ARCP’s then current credit rating). The Loans will initially be priced with an applicable margin of 1.35% in the case of LIBOR revolving loans and 1.60% in the case of LIBOR term loans. In addition, the Agreement provides the flexibility for interest rate auctions, pursuant to which, at the Company’s election, the Company may request that lenders make competitive bids to provide revolving loans, which competitive bids may be at pricing levels that differ from the foregoing interest rates.
	The Agreement provides for monthly interest payments under the Credit Facility. In the event of default, at the election of the majority of the lenders (or automatically upon a bankruptcy event of default with respect to the OP or the Company), the commitments of the lenders under the Credit Facility terminate, and payment of any unpaid amounts in respect of the Credit Facility is accelerated. The revolving credit facility and the term loan facility both terminate on June 30, 2018, in each case, unless extended in accordance with the terms of the Agreement. The Agreement provides for a one-year extension option with respect to each of the revolving credit facility and the term loan facility, exercisable at the Company’s election and subject to certain customary conditions, as well as certain customary “amend and extend” provisions. At any time, upon timely notice by the OP and subject to any breakage fees, the OP may prepay borrowings under the Credit Facility (subject to certain limitations applicable to the prepayment of any loans obtained through an interest rate auction, as described above). The OP incurs a fee equal to 0.15% to 0.25% per annum (based upon ARCP’s then current credit rating) multiplied by the commitments (whether or not utilized) in respect of the dollar revolving credit facility and the multi-currency credit facility. The OP incurs an unused fee of 0.25% per annum on the unused amount of the delayed draw term loan commitments. In addition, the OP incurs customary administrative agent, letter of credit issuance, letter of credit fronting, extension and other fees.
	The Credit Facility requires restrictions on corporate guarantees, as well as the maintenance of financial covenants, including the maintenance of certain financial ratios (such as specified debt to equity and debt service coverage ratios) and the maintenance of a minimum net worth. At September 30, 2014, the OP was in compliance with the debt covenants under the Credit Facility.
	In connection with the Agreement, the Company expensed $3.9 million of unamortized deferred financing costs incurred in connection with the original Credit Facility, which is included in interest expense, net in the accompanying consolidated unaudited statements of operations.
	As of September 30, 2014, the outstanding balance on the Credit Facility was $4.3 billion, of which $3.3 billion bore a floating interest rate of 1.50% at September 30, 2014. The remaining outstanding balance on the Credit Facility of $1.0 billion is fixed through the use of derivative instruments used to hedge interest rate volatility. Including the spread, which can vary based on ARCP’s credit rating, the interest rate on this portion was 2.84% at September 30, 2014. At September 30, 2014, a maximum of $391.0 million was available to the OP for future borrowings, subject to borrowing availability. The credit facility matures on June 30, 2018.
	Subsequent to September 30, 2014, the Company repaid $1.21 billion outstanding on the revolving credit facility with proceeds from the sale of the Multi-Tenant Portfolio (defined below). See Note 22 — Property Dispositions for further discussion and Note 24 — Subsequent Events.
	Repayment of Previous Credit Facilities
	As part of the ARCT IV Merger, the Company assumed a $800.0 million senior unsecured credit facility with various lenders, with Regions Bank acting as the administrative agent (the “ARCT IV Credit Facility”). As of the date of the ARCT IV Merger, there was $760.0 million outstanding under the ARCT IV Credit Facility, which consisted of a $300.0 million term loan facility and $460.0 million under the revolving credit facility. In connection with the ARCT IV Merger, the Company prepaid all of its loans pursuant to, and terminated all commitments available under, the ARCT IV Credit Facility.
	As part of the CapLease Merger, the Company assumed an unsecured credit facility with Wells Fargo, National Association, which had commitments of up to $150.0 million. In February 2014, such credit facility was amended and certain modifications were made to the terms of the agreement (the “CapLease Credit Facility”). On June 6, 2014, the Company repaid the outstanding balance of $150.0 million and terminated the credit facility agreement. No prepayment premium or penalty was paid in connection with the termination of the CapLease Credit Facility.
	On February 28, 2013, the Company repaid all of the outstanding borrowings under its previous senior secured revolving credit facility in the amount of $124.6 million and the credit agreement for such facility was terminated. The average interest rate on the borrowings during the period the balance was outstanding was 3.11%. On February 14, 2013, simultaneous with entering into the Credit Facility, the Company terminated its then effective unsecured credit facility agreement, which had been unused.

Derivatives_and_Hedging_Activi

Derivatives and Hedging Activities	9 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Note 15 — Derivatives and Hedging Activities
	Risk Management Objective of Using Derivatives
	The Company may use derivative financial instruments, including interest rate swaps, caps, options, floors and other interest rate derivative contracts, to hedge all or a portion of the interest rate risk associated with its borrowings. The principal objective of such arrangements is to minimize the risks and/or costs associated with the Company’s operating and financial structure as well as to hedge specific anticipated transactions. The Company does not intend to utilize derivatives for speculative or other purposes other than interest rate risk management. The use of derivative financial instruments carries certain risks, including the risk that the counterparties to these contractual arrangements are not able to perform under the agreements. To mitigate this risk, the Company only enters into derivative financial instruments with counterparties with high credit ratings and with major financial institutions with which the Company and its affiliates may also have other financial relationships. The Company does not anticipate that any of the counterparties will fail to meet their obligations.
	Cash Flow Hedges of Interest Rate Risk
	The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps and collars as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Interest rate collars designated as cash flow hedges involve the receipt of variable-rate amounts if interest rates rise above the cap strike rate on the contract and payments of variable-rate amounts if interest rates fall below the floor strike rate on the contract.
	The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the nine months ended September 30, 2014, such derivatives were used to hedge the variable cash flows associated with variable-rate debt. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings.
	Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate debt. During the next 12 months, the Company estimates that an additional $10.3 million will be reclassified from other comprehensive income as an increase to interest expense.
	As of September 30, 2014, the Company had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk (dollar amounts in thousands):
	Interest Rate Derivative	Number of				Notional Amount
		Instruments
	Interest rate swaps		18			$	1,249,188
	The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the consolidated balance sheets as of September 30, 2014 and December 31, 2013 (in thousands):

	In January 2014, the Company entered into an interest rate lock agreement with a notional amount of $250.0 million (the “Treasury Lock Agreement”). The Treasury Lock Agreement, which had an original maturity date of February 12, 2014, was entered into to hedge part of the Company’s interest rate exposure associated with the variability in future cash flows attributable to changes in the ten-year U.S. treasury rates related to the planned issuance of debt securities in conjunction with the Cole Merger. In connection with the Company’s bond offering in February 2014, the Company settled the Treasury Lock Agreement, which was accounted for as cash flow hedge, for $3.9 million, which was recorded to other comprehensive loss and will be amortized into earnings over the ten year term of the Treasury Lock. The Company amortized $0.1 million and $0.2 million into interest expense for the three and nine months ended September 30, 2014, respectively, related to the Treasury Lock.
	Derivatives Not Designated as Hedging Instruments
	Derivatives not designated as hedges are not speculative and are used to manage the Company’s exposure to interest rate movements and other identified risks but do not meet the requirements to be classified as hedging instruments. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings and were approximately a loss of $17.5 million and a loss of $10.4 million for the three and nine months ended September 30, 2014, respectively. The Company recorded a loss of $38.7 million and $69.8 million for the three and nine months ended September 30, 2013 relating to the contingent value rights.
	As of September 30, 2014, the Company had the following outstanding interest rate derivatives that were not designated as qualifying hedging relationships (dollar amounts in thousands):
	Interest Rate Derivative	Number of Instruments				Notional Amount
	Interest rate swaps		4			$	144,800

	Credit-risk-related Contingent Features
	The Company has agreements with each of its derivative counterparties that contain a provision where, if the Company either defaults or is capable of being declared in default on any of its indebtedness, then the Company could also be declared in default on its derivative obligations.
	As of September 30, 2014, the fair value of the interest rate derivatives in a net liability position, including accrued interest but excluding any adjustment for nonperformance risk related to these agreements, was $7.7 million. As of September 30, 2014, the Company has not posted any collateral related to these agreements and was not in breach of any agreement provisions. If the Company had breached any of these provisions, it could have been required to settle its obligations under the agreements at their aggregate termination value of $7.7 million at September 30, 2014.

	Litigation
	In the ordinary course of business, the Company may become subject to litigation or claims. There are no material legal proceedings pending or known to be contemplated against the Company, except as follows:
	ARCT III Litigation Matters
	After the announcement of the ARCT III Merger Agreement on December 17, 2012, Randell Quaal filed a putative class action lawsuit filed on January 30, 2013 against the Company, the OP, ARCT III, ARCT III OP, the members of the board of directors of ARCT III and certain subsidiaries of the Company in the Supreme Court of the State of New York. The plaintiff alleges, among other things, that the board of ARCT III breached its fiduciary duties in connection with the transactions contemplated under the ARCT III Merger Agreement. In February 2013, the parties agreed to a memorandum of understanding regarding settlement of all claims asserted on behalf of the alleged class of ARCT III stockholders. In connection with the settlement contemplated by that memorandum of understanding, the class action and all claims asserted therein will be dismissed, subject to court approval. The proposed settlement terms required ARCT III to make certain additional disclosures related to the ARCT III Merger, which were included in a Current Report on Form 8-K filed by ARCT III with the SEC on February 21, 2013. The memorandum of understanding also added that the parties will enter into a stipulation of settlement, which will be subject to customary conditions, including confirmatory discovery and court approval following notice to ARCT III’s stockholders. If the parties enter into a stipulation of settlement, a hearing will be scheduled at which the court will consider the fairness, reasonableness and adequacy of the settlement. There can be no assurance that the parties will ultimately enter into a stipulation of settlement, that the court will approve any proposed settlement, or that any eventual settlement will be under the same terms as those contemplated by the memorandum of understanding, therefore any losses that may be incurred to settle this matter are not determinable.
	CapLease Litigation Matters
	Since the announcement of the CapLease Merger Agreement on May 28, 2013, the following lawsuits have been filed:
	On May 28, 2013, Jacquelyn Mizani filed a putative class action lawsuit in the Supreme Court for the State of New York against the Company, the OP, Safari Acquisition LLC, CapLease, CapLease LP, CLF OP General Partner, LLC and the members of the CapLease board of directors (the “Mizani Action”). The complaint alleges, among other things, that the merger agreement at issue was the product of breaches of fiduciary duty by the CapLease directors because the proposed merger transaction (the “CapLease Transaction”) purportedly does not provide for full and fair value for the CapLease shareholders, the CapLease Transaction allegedly was not the result of a competitive bidding process, the merger agreement allegedly contains coercive deal protection measures and the merger agreement and the CapLease Transaction purportedly were approved as a result of improper self-dealing by certain defendants who would receive certain alleged employment compensation benefits and continued employment pursuant to the merger agreement. The complaint also alleges that CapLease, the Company, the OP and Safari Acquisition LLC aided and abetted the CapLease directors’ alleged breaches of fiduciary duty.
	On July 3, 2013, Fred Carach filed a putative class action and derivative lawsuit in the Supreme Court for the State of New York against the Company, the OP, Safari Acquisition LLC, CapLease, CapLease LP, CLF OP General Partner, LLC and the members of the CapLease board of directors (the “Carach Action”). The complaint alleges, among other things, that the merger agreement was the product of breaches of fiduciary duty by the CapLease directors because the merger purportedly does not provide for full and fair value for the CapLease shareholders, the CapLease Transaction allegedly was not the result of a competitive bidding process, the merger agreement allegedly contains coercive deal protection measures and the merger agreement and the CapLease Transaction purportedly were approved as a result of improper self-dealing by certain defendants who would receive certain alleged employment compensation benefits and continued employment pursuant to the merger agreement. The complaint also alleges that with respect to the Registration Statement and draft joint proxy statement issued in connection with the proposed CapLease Transaction on July 2, 2013, that disclosures made therein were insufficient or otherwise improper. The complaint also alleges that CapLease LP, CLF OP General Partner, LLC, the Company, the OP and Safari Acquisition LLC aided and abetted the CapLease directors’ alleged breaches of fiduciary duty.
	On June 25, 2013, Dewey Tarver filed a putative class action and derivative lawsuit in the Circuit Court for Baltimore City against the Company, the OP, Safari Acquisition LLC, CapLease, CapLease LP, CLF OP General Partner, LLC and the members of the CapLease board of directors (the “Tarver Action”). The complaint alleges, among other things, that the merger agreement was the product of breaches of fiduciary duty by the CapLease directors because the CapLease Transaction purportedly does not provide for full and fair value for the CapLease shareholders, the CapLease Transaction allegedly was not the result of a competitive bidding process, the merger agreement allegedly contains coercive deal protection measures and the merger agreement and the CapLease Transaction purportedly were approved as a result of improper self-dealing by certain defendants who would receive certain alleged employment compensation benefits and continued employment pursuant to the merger agreement. The complaint also alleges that CapLease, CapLease LP, CLF OP General Partner, LLC, the Company, the OP and Safari Acquisition, LLC aided and abetted the CapLease directors’ alleged breaches of fiduciary duty.
	Counsel who filed each of these three cases reached an agreement with each other as to who will serve as lead plaintiff and lead plaintiffs’ counsel in the cases and where they will be prosecuted. Thus, on August 9, 2013, counsel in the Tarver Action filed a motion for stay in the Baltimore Court, informing the court that they had agreed to join and participate in the prosecution of the Mizani and Carach Actions in the New York Court. The Defendants consented to the stay of the Tarver Action in the Baltimore Court, and on September 5, 2013, Judge Pamela J. White issued an order granting that stay. Consequently, there has been no subsequent activity in the Baltimore Court in the Tarver Action. Also on August 9, 2013, all counsel involved in the Mizani and Carach Actions filed a joint stipulation in the New York Court, reflecting agreement among all parties that the Mizani and Carach Actions should be consolidated (jointly, “the Consolidated Actions”) and setting out a schedule for early motion practice in response to the complaints filed (the “Consolidation Stipulation”). Pursuant to the Consolidation Stipulation, an amended complaint was also filed in the New York court on August 9, 2013 and was designated as the operative complaint in the Consolidated Actions (“Operative Complaint”). Pursuant to the Consolidation Stipulation, all Defendants filed a motion to dismiss all claims asserted in the Operative Complaint on September 23, 2013. Plaintiffs’ response was due on or before November 7, 2013. On November 7, 2013, Plaintiffs filed a motion seeking leave to file a second amended complaint, which the Defendants opposed. On March 24, 2014, Plaintiffs’ counsel in the Consolidated Actions dismissed those claims without prejudice. Consequently, only the Tarver Action currently remains pending among these cases, although it remains stayed.
	On October 8, 2013, John Poling filed a putative class action lawsuit in the Circuit Court for Baltimore City against the Company, the OP, Safari Acquisition LLC, CapLease, CapLease LP, CLF OP General Partner, LLC and the members of the CapLease board of directors (the “Poling Action”). The complaint alleges that the merger agreement breaches the terms of the CapLease 8.375% Series B Cumulative Redeemable Preferred Stock (“Series B”) and the terms of the 7.25% Series C Cumulative Redeemable Preferred Stock (“Series C”) and is in violation of the Series B Articles Supplementary and the Series C Articles Supplementary. The Complaint alleges claims for breach of contract and breach of fiduciary duty against the CapLease entities and the CapLease board of directors. The complaint also alleges that the Company, the OP and Safari Acquisition, LLC aided and abetted CapLease and the CapLease directors’ alleged breach of contract and breach of fiduciary duty.
	On November 13, 2013, all counsel involved in the Poling Action filed a joint stipulation, reflecting agreement among all parties concerning a schedule for early motion practice in response to the complaint filed (the “Scheduling Stipulation”). Pursuant to the Scheduling Stipulation, all Defendants filed a motion to dismiss all claims asserted in the Operative Complaint on December 20, 2013. Plaintiff has filed an opposition to that motion, which remains pending.
	Cole Litigation Matters
	Three putative class action and/or derivative lawsuits, which were filed in March and April 2013, assert claims for breach of fiduciary duty, abuse of control, corporate waste, unjust enrichment, aiding and abetting breach of fiduciary duty and other claims relating to the merger between a wholly owned subsidiary of Cole and Cole Holdings Corporation, pursuant to which Cole became a self-managed REIT. On October 22, 2013, the Circuit Court for Baltimore City granted all defendants’ motion to dismiss with prejudice the action pending before the court, but the plaintiffs appealed that dismissal. On July 31, 2014, plaintiffs dismissed the pending appeal based on an agreement by defendants to reimburse plaintiffs in the amount of $100,000. The other two lawsuits, which also purport to assert shareholder class action claims under the Securities Act of 1933, as amended (the “Securities Act”), are pending in the United States District Court for the District of Arizona. Defendants filed a motion to dismiss both complaints on January 10, 2014. Subsequently, both of those lawsuits have been stayed by the Court pursuant to a joint request made by all parties pending final approval of the consolidated Baltimore Cole Merger Actions described below.
	To date, eleven lawsuits have been filed in connection with the Cole Merger. Two of these suits - Wunsch v. Cole, et al. (“Wunsch”), No. 13-CV-2186, and Sobon v. Cole, et al. (“Sobon”) - were filed as putative class actions on October 25, 2013 and November 18, 2013, respectively, in the U.S. District Court for the District of Arizona. Between October 30, 2013 and November 14, 2013, eight other putative stockholder class action or derivative lawsuits were filed in the Circuit Court for Baltimore City, Maryland, captioned as: (i) Operman v. Cole, et al. (“Operman”); (ii) Branham v. Cole, et al. (“Branham”); (iii) Wilfong v. Cole, et al. (“Wilfong”); (iv) Polage v. Cole, et al. (“Polage”); (v) Corwin v. Cole, et al. (“Corwin”); (vi) Green v. Cole, et al. (“Green”); (vii) Flynn v. Cole, et al. (“Flynn”) and (viii) Morgan v. Cole, et al. (“Morgan”). All of these lawsuits name the Company, Cole and Cole’s board of directors as defendants; Wunsch, Sobon, Branham, Wilfong, Flynn, Green, Morgan and Polage also name CREInvestments, LLC, a Maryland limited liability company and a wholly-owned subsidiary of the Cole, as a defendant. All of the named plaintiffs claim to be Cole stockholders and purport to represent all holders of Cole’s stock. Each complaint generally alleges that the individual defendants breached fiduciary duties owed to plaintiff and the other public stockholders of Cole in connection with the Cole Merger, and that certain entity defendants aided and abetted those breaches. The breach of fiduciary duty claims asserted include claims that the Cole Merger did not provide for full and fair value for the Cole shareholders, that the Cole Merger was the product of an “inadequate sale process,” that the Cole Merger Agreement contained coercive deal protection measures and that the Cole Merger Agreement and the Cole Merger were approved as a result of or in a manner which facilitates improper self-dealing by certain defendants. In addition, the Flynn, Corwin, Green, Wilfong, Polage and Branham lawsuits claim that the individual defendants breached their duty of candor to shareholders and the Branham and Polage lawsuits assert claims derivatively against the individual defendants for their alleged breach of fiduciary duties owed to Cole. The Polage lawsuit also asserts derivative claims for waste of corporate assets and unjust enrichment. The Wunsch and Sobon lawsuits also assert claims against Cole and the individual defendants under Section 14(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), based on allegations that the proxy materials omitted to disclose allegedly material information, and a claim against the individual defendants under Section 20(a) of the Exchange Act based on the same allegations. Among other remedies, the complaints seek unspecified money damages, costs and attorneys’ fees.
	In January 2014, the parties to the eight lawsuits filed in the Circuit Court for Baltimore City, Maryland (the “consolidated Baltimore Cole Merger Actions”) entered into a memorandum of understanding regarding settlement of all claims asserted on behalf of the alleged class of Cole stockholders. In connection with the settlement contemplated by that memorandum of understanding, the class action and all claims asserted therein would be dismissed, subject to court approval. The proposed settlement terms required Cole to make certain additional disclosures related to the Cole Merger, which were included in a Current Report on Form 8-K filed by Cole with the SEC on January 14, 2014. The memorandum of understanding also contemplated that the parties would enter into a stipulation of settlement, subject to customary conditions, including confirmatory discovery and court approval following notice to Cole’s stockholders. The Sobon lawsuit was voluntarily dismissed on February 3, 2014.
	On August 14, 2014, the parties in the consolidated Baltimore Merger Actions executed a Stipulation and Release and Agreement of Compromise and Settlement (the “Settlement Stipulation”). The parties in the consolidated Baltimore Merger Actions submitted the Settlement Stipulation, along with related filings, for approval by the Maryland court on August 18, 2014. On August 25, 2014, the Baltimore Circuit Court entered an Order on Preliminary Approval of Derivative and Class Action Settlement and Class Action Certification and scheduled a final settlement hearing in the consolidated Baltimore Merger Actions.
	On December 27, 2013, Realistic Partners filed a putative class action lawsuit against the Company and the members of its board of directors in the Supreme Court for the State of New York. Cole was later added as a defendant also. The plaintiff alleges, among other things, that the board of the Company breached its fiduciary duties in connection with the transactions contemplated under the Cole Merger Agreement and that Cole aided and abetted those breaches. In January 2014, the parties entered into a memorandum of understanding regarding settlement of all claims asserted on behalf of the alleged class of the Company’s stockholders. In connection with the settlement contemplated by that memorandum of understanding, the class action and all claims asserted therein will be dismissed, subject to court approval. The proposed settlement terms required the Company to make certain additional disclosures related to the Cole Merger, which were included in a Current Report on Form 8-K filed by the Company with the SEC on January 17, 2014. The memorandum of understanding also contemplated that the parties will enter into a stipulation of settlement, which will be subject to customary conditions, including confirmatory discovery and court approval following notice to the Company’s stockholders. If the parties enter into a stipulation of settlement, a hearing will be scheduled at which the court will consider the fairness, reasonableness and adequacy of the settlement. There can be no assurance that the parties will ultimately enter into a stipulation of settlement, that the court will approve any proposed settlement, or that any eventual settlement will be under the same terms as those contemplated by the memorandum of understanding, therefore any losses that may be incurred to settle this matter are not determinable.
	Contractual Lease Obligations

	Purchase Commitments
	Cole Capital enters into purchase and sale agreements and deposits funds into escrow towards the purchase of such acquisitions, some of which are expected to be assigned to one of the Managed REITs at or prior to the closing of the respective acquisition. As of September 30, 2014, the Company was a party to 70 purchase and sale agreements with unaffiliated third-party sellers to purchase a 100% interest in 303 properties, subject to meeting certain criteria, for an aggregate purchase price of $1.2 billion, exclusive of closing costs. As of September 30, 2014, the Company had $36.9 million of property escrow deposits held by escrow agents in connection with these future property acquisitions, which may be forfeited if the transactions are not completed under certain circumstances. The Company will be reimbursed by the assigned Managed REIT for amounts escrowed when it acquires a property.
	Environmental Matters
	In connection with the ownership and operation of real estate, the Company may potentially be liable for costs and damages related to environmental matters. The Company has not been notified by any governmental authority of any non-compliance, liability or other claim, and is not aware of any other environmental condition, in each case, that it believes will have a material adverse effect on the results of operations.

Equity [Abstract]
Preferred and Common Stock and OP Units	Note 18 — Preferred and Common Stock and OP Units
	Series D and Series E Preferred Stock and OP Units
	On September 12, 2013, the General Partner’s board of directors unanimously approved the issuance of Series D Cumulative Convertible Preferred Stock (“Series D Preferred Stock”) and the issuance of Series E Cumulative Preferred Stock (“Series E Preferred Stock”). Concurrently, the Operating Partnership was approved to issue to the General Partner Series D Cumulative Convertible Preferred Units (“Series D Preferred Units”) and Series E Cumulative Preferred Units (“Series E Preferred Units”), if applicable.
	On September 15, 2013, the General Partner entered into definitive purchase agreements pursuant to which it agreed to issue Series D Preferred Stock and common stock to certain institutional holders, necessitating that the Operating Partnership concurrently issue to the General Partner Series D Preferred Units and General Partner OP Units, promptly following the close of the CapLease Merger. Pursuant to the definitive purchase agreements, the General Partner issued approximately 21.7 million shares of Series D Preferred Stock and 15.1 million shares of ARCP common stock, for gross proceeds of $288.0 million and $186.0 million, respectively, on November 8, 2013. The Operating Partnership concurrently issued 21.7 million Series D Preferred Units and 15.1 million General Partner OP Units to the General Partner. The Series D Preferred Stock and Series D Preferred Units pay dividends at the rate of 5.81% per annum on their face amount of $13.59 per share (equivalent to $0.79 per share on an annualized basis). The Company redeemed all outstanding Series D Preferred Stock and Units on September 2, 2014 (the “Redemption Date”) for $316.1 million in cash.
	As the holders of Series D Preferred Stock were entitled to receive liquidation preferences that other equity holders were not entitled to, the Company classified the Series D Preferred Stock as temporary equity. At the date of issuance, the fair value of the Series D Preferred Stock was $269.3 million.
	Prior to redemption, the General Partner had concluded that the conversion option qualified as a derivative and should be bifurcated from the host instrument. At issuance, the conversion option had a fair value of $18.7 million. As of December 31, 2013, the fair value of the conversion option was $16.7 million. The Company recorded losses of $18.8 million and $13.6 million upon redemption of the conversion option in gain (loss) on derivative instruments, net in the consolidated statements of operations for the three and nine months ended September 30, 2014, respectively.
	As of September 30, 2014, there were no issued shares of Series D Preferred Stock and no authorized and issued shares of Series E Preferred Stock. Therefore, no equivalent units were issued and outstanding at the Operating Partnership.
	Series F Preferred Stock and Series F Preferred Units
	On October 6, 2013, in connection with the modification to the ARCT IV Merger, the General Partner’s board of directors unanimously approved the issuance of Series F Preferred Stock. Upon consummation of the ARCT IV Merger on January 3, 2014, 42.2 million shares of Series F Preferred Stock were issued to ARCT IV shareholders, resulting in the Operating Partnership concurrently issuing 42.2 million General Partner Series F Preferred Units to the General Partner, and 0.7 million Limited Partner Series F Preferred Units were issued to the ARCT IV OP Unit holders. Subsequent to original issuance and through September 30, 2014, 0.6 million Limited Partner Series F Preferred Units were converted into an equivalent number of the General Partner’s Series F Preferred Stock. Concurrently, 0.6 million General Partner Series F Preferred Units were issued to the General Partner. As of September 30, 2014, there were 42.8 million shares of Series F Preferred Stock and 0.1 million Series F OP Units issued and outstanding.
	The Series F Preferred Units contain the same terms as the Series F Preferred Stock. Therefore, the Series F Preferred Stock/Units will pay cumulative cash dividends at the rate of 6.70% per annum on their liquidation preference of $25.00 per share/unit (equivalent to $1.675 per share/unit on an annual basis). The Series F Preferred Stock is not redeemable by the Company before the fifth anniversary of the date on which such Series F Preferred Stock is issued (the “Initial Redemption Date”), except under circumstances intended to preserve the General Partner’s status as a real estate investment trust for federal and/or state income tax purposes and except upon the occurrence of a change of control. On and after the Initial Redemption Date, the Company may, at its option, redeem shares of the Series F Preferred Stock, in whole or from time to time in part, at a redemption price of $25.00 per share plus, subject to exceptions, any accrued and unpaid dividends thereon to the date fixed for redemption. The shares of Series F Preferred Stock have no stated maturity, are not subject to any sinking fund or mandatory redemption and will remain outstanding indefinitely unless the Company redeems or otherwise repurchases them or they become convertible and are converted into General Partner’s common stock or General Partner OP Units (or, if applicable, alternative consideration). The Series F Preferred Stock of the General Partner trades on the NASDAQ under the symbol “ARCPP.”
	Increases in Authorized Common Stock
	On December 9, 2013, the Company filed articles of amendment to its charter to increase the number of authorized shares of common stock to 1.5 billion shares.
	Offerings
	On August 1, 2012, the General Partner filed a $500.0 million universal shelf registration statement and a resale registration statement with the SEC. Each registration statement became effective on August 17, 2012. As of September 30, 2014, the General Partner had issued 2.1 million shares of common stock and no preferred stock, debt or equity-linked security had been issued under the universal shelf registration statement. Concurrently with the General Partner’s issuance of the $2.1 million shares of common stock referenced above, the Operating Partnership issued 2.1 million General Partner OP Units to the General Partner. The resale registration statement, as amended, registers the resale of up to 1,882,248 shares of ARCP’s common stock issued in connection with any future conversion of certain currently outstanding restricted shares, preferred stock or Limited Partner OP Units.
	In January 2013, the General Partner commenced its “at the market” equity offering program (“ATM”) in which it may from time to time offer and sell shares of its common stock having aggregate offering proceeds of up to $60.0 million. The shares will be issued pursuant to the General Partner’s universal shelf registration statement. For each share of common stock the General Partner sells under the ATM, the Operating Partnership will issue a corresponding General Partner OP Unit to the General Partner.
	On March 14, 2013, the General Partner filed a universal automatic shelf registration statement that was automatically declared effective and achieved well-known seasoned issuer (“WKSI”) status. As a result of the delayed filing of certain of our periodic reports with the SEC, the General Partner is not currently eligible to use a shelf registration statement for the offer and sale of our securities.
	On May 28, 2014, the General Partner closed on a public offering of 138.0 million shares of ARCP common stock at a price of $12.00 per share. The net proceeds to ARCP were approximately $1.59 billion after deducting underwriting discounts, commissions and offering-related expenses, which include a $2.0 million structuring fee paid to RCS. Concurrently, the Operating Partnership issued the General Partner 138.0 million General Partner OP Units.
	Dividends
	In October 2011, the Company began paying dividends on the 15th day of each month to stockholders/unitholders of record on the eighth day of such month. On October 23, 2013, the board of directors of ARCP authorized an annualized dividend per share of $1.00, which became effective February 7, 2014. The per share/unit annualized dividend of $1.00 reflects an increase of $0.06 per share from an annualized dividend of $0.94 per share. The annualized dividend rate at September 30, 2014 was $1.00 per share.
	Common Stock Repurchases
	On August 20, 2013, the Company’s board of directors reauthorized its $250.0 million share repurchase program, which was originally authorized in February 2013. During the nine months ended September 30, 2014, the Company did not repurchase any shares of common stock under the share repurchase program.
	Upon the closing of the ARCT III Merger, on February 28, 2013, 29.2 million shares, or 16.5% of the then-outstanding shares of ARCT III’s common stock, were paid in cash at $12.00 per share, which is equivalent to 27.7 million shares of the Company’s common stock based on the ARCT III Exchange Ratio. In addition, 148.1 million shares of ARCT III’s common stock were converted to shares of the Company’s common stock at the ARCT III Exchange Ratio, resulting in an additional 140.7 million shares of the Company’s common stock outstanding after the exchange.

Equity-based Compensation	9 Months Ended
	Sep. 30, 2014
Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity-based Compensation	Note 19 — Equity-based Compensation
	Equity Plan
	The General Partner has adopted the American Realty Capital Properties, Inc. Equity Plan (the “Equity Plan”), which provides for the grant of stock options, stock appreciation rights, restricted shares of common stock, restricted stock units, dividend equivalent rights and other stock-based awards to the General Partner’s and its affiliates’ non-executive directors, officers and other employees and advisors or consultants who are providing services to the General Partner or its affiliates. For each share awarded under the Equity Plan, the Operating Partnership issues a General Partner OP Unit to the General Partner with identical terms.
	The General Partner authorized and reserved a total number of shares equal to 10.0% of the total number of issued and outstanding shares of common stock (on a fully diluted basis assuming the redemption of all OP Units for shares of common stock) to be issued at any time under the Equity Plan for equity incentive awards excluding an initial grant of 167,400 shares to the Former Manager in connection with the IPO, all of which were vested as of September 30, 2014. As of September 30, 2014, the General Partner has awarded 6,834,695 shares under the Equity Plan and the Operating Partnership has issued 6,834,695 General Partner OP Units to the General Partner underlying such shares issued under the Equity Plan. In the first quarter of 2014, the Company issued 282,854 shares to its non-executive directors pursuant to the Equity Plan. Upon issuance, the documentation provided for accelerated vesting of shares upon voluntary resignation of the independent directors. As a result, the Company determined there was no required service period and $3.6 million has been recorded as expense during the nine months ended September 30, 2014. However, based upon the findings of the Audit Committee and the Company in connection with the recent review of the Company’s previously filed financial statements, the Company subsequently modified such awards to provide that voluntary resignation would not accelerate the vesting of such awards.
	The fair value of restricted common stock awards awarded to employees under the Equity Plan is generally determined on the grant date using the closing stock price on NASDAQ that day and is expensed over the requisite service period. The fair value of restricted common stock awarded to non-employees under the Equity Plan is measured based upon the fair value of goods or services received or the equity instruments granted, whichever is more reliably determinable and is typically expensed in full at the date of grant.
	Director Stock Plan
	The General Partner has adopted a Non-Executive Director Stock Plan (the “Director Stock Plan”), which provides for the grant of restricted shares of common stock to each of the General Partner’s non-executive directors. Awards of restricted stock will vest in accordance with the award agreements, which generally provide for ratable vesting over a five-year period following the date of grant. The awards of restricted stock provide for “distribution equivalents” with respect to this restricted stock, whether or not vested, at the same time and in the same amounts as distributions are paid to the stockholders. At September 30, 2014, a total of 99,000 shares of common stock are reserved for issuance under the Director Stock Plan. As of September 30, 2014, the General Partner has awarded 45,000 shares under the Director Stock Plan and the Operating Partnership has issued 45,000 General Partner OP Units to the General Partner in connection with the Director Stock Plan.
	The fair value of restricted common stock awards, as well as the underlying General Partner OP Units, under the Director Stock Plan is determined on the grant date using the closing stock price on NASDAQ that day.
	ARCT IV Restricted Share Plan
	ARCT IV had an employee and director incentive restricted share plan (the “RSP”), which provided for the automatic grant of 1,333 restricted shares of common stock to each of its independent directors without any further action by ARCT IV’s board of directors or its stockholders on the date of initial election to the board of directors and on the date of each annual stockholder’s meeting thereafter. Restricted stock issued to independent directors vested over a five-year period following the date of grant in increments of 20% per annum. The RSP provided ARCT IV with the ability to grant awards of restricted shares to its directors, officers and employees (if ARCT IV ever had employees), employees of the ARCT IV Advisor and its affiliates, employees of entities that provided services to ARCT IV, directors of the ARCT IV Advisor or of entities that provided services to ARCT IV, certain consultants to ARCT IV and the ARCT IV Advisor and its affiliates or to entities that provided services to ARCT IV.
	Immediately prior to the effective time of the ARCT IV Merger, each then-outstanding share of ARCT IV restricted stock fully vested. All shares of ARCT IV common stock then-outstanding as a result of the full vesting of shares of ARCT IV restricted stock, and the satisfaction of any applicable withholding taxes, received shares of the Company’s common stock and additional consideration pursuant to the terms of the ARCT IV Merger Agreement based on the ARCT IV Exchange Ratio. Concurrently, for each share of ARCP common stock or Series F Preferred Stock issued, the Operating Partnership issued a General Partner OP Unit or General Partner Series F Preferred Unit to the General Partner, respectively.
	The following table details the restricted shares activity within the Equity Plan and Director Stock Plan during the nine months ended September 30, 2014:
			Equity Plan								Director Stock Plan
			Shares of				Weighted-Average				Shares of				Weighted-Average
			Restricted Common				Issue Price				Restricted Common				Issue Price

	Unvested, September 30, 2014			5,803,494			$	13.38				—			$	—
	For the three and nine months ended September 30, 2014, compensation expense, excluding Outperformance Bonus expense related to the OPP, for restricted shares was $2.8 million and $23.2 million, respectively, which is recorded in general and administrative on the consolidated statement of operations.
	Compensation expense for the nine months ended September 30, 2014 includes $11.4 million of compensation expense recorded for 0.8 million restricted shares granted to affiliates.
	Multi-Year Outperformance Plan
	Upon consummation of the ARCT III Merger, the Company entered into the 2013 Advisor Multi-Year Outperformance Agreement (the “OPP”) with the Former Manager, whereby the Former Manager was able to potentially earn compensation upon the attainment of stockholder value creation targets.
	Under the OPP, the Company’s Former Manager was granted 8,241,101 long-term incentive plan units of the OP (“LTIP Units”), which could be earned or forfeited based on the General Partner’s total return to stockholders (including both share price appreciation and common stock distributions) (“Total Return”), for the three-year period that commenced on December 11, 2012.
	Pursuant to previous authorization of the General Partner’s board of directors, as a result of the termination of the Management Agreement, all 8,241,101 LTIP Units became fully earned, vested and convertible into OP Units upon the consummation of the Company’s transition to self-management on January 8, 2014 and were converted to OP Units on such date. During the nine months ended September 30, 2014, the Operating Partnership recorded expenses of $1.6 million for the LTIP Units under the OPP, which is recorded in general and administrative in the accompanying consolidated statements of operations. As of September 30, 2014, all LTIP Units under the OPP were earned and $93.9 million of the expense has been allocated to the non-controlling interest on the consolidated balance sheet.
	New Multi-Year Outperformance Plan
	On October 3, 2013, the General Partner approved a multi-year outperformance plan (the “New OPP”), which became effective upon the General Partner’s transition to self-management, which occurred on January 8, 2014. Under the New OPP, individual agreements were entered into between the General Partner and the participants selected by the General Partner’s board of directors (the “Participants”) that set forth the Participant’s participation percentage in the New OPP and the number of LTIP Units of the OP subject to the award (“OPP Agreements”). Under the New OPP and the OPP Agreements, the Participants are eligible to earn performance-based bonus awards equal to the Participant’s participation percentage of a pool that is funded up to a maximum award opportunity (the “New OPP Cap”) of approximately 5% of the General Partner’s equity market capitalization at the time of the approval of the New OPP (“the Initial Market Cap”).
	After the Audit Committee’s and the General Partner’s review of the OPP, such parties have determined that the Compensation Committee’s intention in respect of the OPP was that the maximum award pool opportunity should have been $120.0 million. In October 2013, the Compensation Committee approved an aggregate award pool to be measured by the General Partner’s market capitalization as of the date of such approval; however, the OPP was definitively documented to measure market capitalization on a pro forma basis as of the General Partner’s transition to self-management (including the pro forma impact of various transactions expected to be consummated prior to the General Partner’s transition to self-management on January 8, 2014), which was calculated in December 2013.
	Subject to the New OPP Cap, the pool will equal an amount to be determined based on the General Partner’s level of achievement of total return to stockholders, including both share price appreciation and common stock distributions (“Total Return”), as measured against an absolute hurdle and against a peer group of companies for a three-year performance period that commenced on October 1, 2013 (the “Performance Period”), with valuation dates on which a portion of the LTIP Units up to a specified amount of the New OPP Cap could be earned on the last day of each 12-month period during the Performance Period (each an “Annual Period”) and the initial 24-month period of the Performance Period (the “Interim Period”), as follows:
					Performance				Annual Period				Interim Period
					Period
	Absolute Component: 4% of any excess Total Return attained above an absolute hurdle measured from the beginning of such period:					21%				7%				14%
	Relative Component: 4% of any excess Total Return attained above the median Total Return for the performance period of the Peer Group(1), subject to a ratable sliding scale factor as follows based on achievement of cumulative Total Return measured from the beginning of such period:
	•		100% will be earned if cumulative Total Return achieved is at least:			18%				6%				12%
	•		50% will be earned if a cumulative Total Return achieved is:			0%				0%				0%
	•		0% will be earned if cumulative Total Return achieved is less than:			0%				0%				0%
	•		a percentage from 50% to 100% calculated by linear interpolation will be earned if cumulative Total Return achieved is if between:			0% - 18%				0% - 6%				0% - 12%
	-1	The “Peer Group” is comprised of the following companies: EPR Properties; Getty Realty Corporation; Lexington Realty Trust; National Retail Properties, Inc.; Realty Income Corporation; and Spirit Realty Capital, Inc.
	The New OPP provides for early calculation and vesting of the award in the event of a change in control of the General Partner, prior to the end of the Performance Period. The Participants are entitled to receive a tax gross-up in the event that any amounts paid to the Participant under the New OPP constitute “parachute payments” as defined in Section 280G of the Code. The LTIP Units granted under the New OPP represent units of equity ownership in the OP that are structured as a profits interest therein. Subject to the Participant’s continued service through each vesting date, one-third of any earned LTIP Units will vest on October 1, 2016, October 1, 2017 and October 1, 2018, respectively. The Participants are entitled to receive distributions on their LTIP Units to the extent provided for in the LPA, as amended from time to time. During the three and nine months ended September 30, 2014, the Company recorded expenses of $2.7 million and $8.0 million, respectively, for the New OPP, which is recorded in equity-based compensation and included with general and administrative expense on the consolidated statement of operations. As of September 30, 2014, the Company had recorded a total payable for distributions on LTIP units related to the OPP and the New OPP of $6.9 million.

The ARCT III Advisor received distributions on unvested ARCT III Class B units equal to the distribution rate received on ARCT III common stock. In 2012, the ARCT III board of directors approved the issuance of 145,022 ARCT III Class B units to the ARCT III Advisor for asset management services it provided. In 2013, the ARCT III board of directors approved issuance of an additional 603,599 ARCT III Class B units to the ARCT III Advisor for asset management services it provided.

In connection with the asset management services provided by the ARCT IV Advisor, ARCT IV issued (subject to periodic approval by ARCT IV’s board of directors) to the ARCT IV Advisor performance-based restricted partnership units of the ARCT IV OP designated as “ARCT IV Class B Units,” which were intended to be profit interests and to vest, and no longer be subject to forfeiture, at such time as: (x) the value of the ARCT IV OP’s assets plus all distributions that equaled or exceeded the total amount of capital contributed by investors plus a 6.0% cumulative, pre-tax, non-compounded annual return thereon (the “economic hurdle”); (y) any one of the following occurs: (1) the termination of the advisory agreement by an affirmative vote of a majority of the Company’s independent directors without cause; (2) a listing; or (3) another liquidity event; and (z) the ARCT IV Advisor was still providing advisory services to ARCT IV.
The calculation of the ARCT IV asset management fees was equal to: (i) 0.1875% of the cost of ARCT IV’s assets; divided by (ii) the value of one share of ARCT IV common stock as of the last day of such calendar quarter. When approved by the board of directors, the ARCT IV Class B Units were issued to the ARCT IV Advisor quarterly in arrears pursuant to the terms of the ARCT IV OP agreement. During the year ended December 31, 2013, ARCT IV’s board of directors approved the issuance of 492,483 ARCT IV Class B Units to the ARCT IV Advisor in connection with this arrangement. As of December 31, 2013, ARCT IV did not consider achievement of the performance condition to be probable and no expense was recorded at that time. The ARCT IV Advisor received distributions on unvested ARCT IV Class B Units equal to the distribution rate received on the ARCT IV common stock. The performance condition related to the 498,857 ARCT IV Class B Units, which includes units issued for the period of January 1, 2014 through the ARCT IV Merger Date, was satisfied upon the completion of the ARCT IV Merger. These ARCT IV Class B Units immediately converted into OP Units at the 2.3961 exchange ratio discussed in Note 3 — Mergers and Acquisitions and the Company recorded an expense of $13.9 million based on the fair value of the ARCT IV Class B Units during the nine months ended September 30, 2014.

Audrain Building
During the year ended December 31, 2013, a wholly owned subsidiary of ARC Real Estate purchased a historic building in Newport, Rhode Island (“Audrain”) with plans to renovate the second floor to serve as offices for certain executives of the Company, and affiliates of the Former Manager. ARC Real Estate requested that invoices relating to the second floor renovation and tenant improvements and all building operating expenses either be reimbursed by the Company to the affiliate of the Former Manager or be paid directly to the contractors and vendors. During the three and nine months ended September 30, 2014, the Company paid $4.7 million and $8.5 million , respectively, for tenant improvements and furniture and fixtures relating to the renovation. These payments were made directly to third parties.
In addition, on October 4, 2013, the Company entered into a lease agreement with the subsidiary of ARC Real Estate for a term of 15 years with annual base rent of $0.4 million requiring monthly payments beginning on that date. As there were tenants occupying the building when it was purchased, these tenants subleased their premises from the Company until their leases terminated. During the three and nine months ended September 30, 2014, the Company incurred and paid $0.1 million and $0.2 million, respectively, for base rent, which was partially offset by $17,000 of rental revenue received from the subtenants during the nine months ended September 30, 2014. No rental revenue was received during the three months ended September 30, 2014.
Subsequent to September 30, 2014, as a result of findings of the investigation conducted by the Audit Committee, the Company terminated the lease agreement and was reimbursed for the tenant improvement and furniture costs incurred by the Company during the nine months ended September 30, 2014 totaling approximately $8.5 million. Reimbursement was made by delivery and retirement of 916,423 OP Units held by an affiliate of the Former Manager. The Company never moved into or occupied the building.
ANST Office Build-out
During the nine months ended September 30, 2014, as a result of the Cole Merger, the Company worked to develop a partnership with ANST to better service clients and shareholders more efficiently, as well as create more career opportunities for the employees. Plans were made to move ANST to part of the Cole Capital office building in 2014. In order to accommodate the ANST employees, the Cole Capital office building was to be remodeled. During the nine months ended September 30, 2014, the Company paid $0.4 million directly to third parties for leasehold improvements and furniture and fixtures relating to the renovation.
Subsequently, ANST never moved into the building. The Company is considering its options with regard to recovery of such payments, although no decisions have been made at this time. No asset has been recognized in the financial statements related to any potential recovery.
Office Rents and New York (405 Park Ave.) Office Build-out
During the three and nine months ended September 30, 2014, the Company paid $0.2 million and $0.5 million, respectively, to an affiliate of the Former Manager for rent related to offices in New York, Pennsylvania and North Carolina where certain of the Company’s employees shared office space with an affiliate of the Former Manager. In addition, during the three and nine months ended September 30, 2014, the Company paid $0.5 million directly to third parties for leasehold improvements and furniture and fixtures for the New York (405 Park Ave.) office.

Net Loss Per Share/Unit	Note 21 — Net Loss Per Share/Unit
	Net Loss Per Share
	The General Partner’s unvested shares of restricted stock contain non-forfeitable rights to dividends and are considered to be participating securities in accordance with GAAP and, therefore, are included in the computation of earnings per share under the two-class method. Under the two-class computation method, net losses are not allocated to participating securities unless the holder of the security has a contractual obligation to share in the losses. The unvested restricted stock is not allocated losses as the awards do not have a contractual obligation to share in losses of ARCP. The two-class method is an earnings allocation formula that determines earnings per share for each class of common shares and participating securities according to dividends declared (or accumulated) and participation rights in undistributed earnings.
	The following is a summary of the basic and diluted net loss per share computation for ARCP for the three and nine months ended September 30, 2014 and 2013 (dollar amounts in thousands, except for share and per share data):

Discontinued Operations and Disposal Groups [Abstract]
Property Dispositions	Note 22 — Property Dispositions
	During the nine months ended September 30, 2014, the Company disposed of 29 single-tenant properties and one multi-tenant property for an aggregate gross sales price of $158.6 million (the “2014 Property Dispositions”). There were no properties disposed of during the nine months ended September 30, 2013. No disposition fees were paid to affiliates in connection with the sale of the 2014 Property Dispositions and the Company has no continuing involvement with these properties. As of September 30, 2014, 71 properties were classified as held for sale.
	On June 11, 2014, the OP, through indirect subsidiaries, entered into an agreement of purchase and sale with BRE DDR Retail Holdings III LLC (the “Purchaser”), a joint venture between Blackstone and DDR Corp., by which the Purchaser agreed to purchase 67 multi-tenant properties and nine single-tenant properties and the adjacent land and related properties. The properties to be sold pursuant to such agreement were the same properties that the Company had previously intended to spin off into an externally managed, NASDAQ-traded REIT, American Realty Capital Centers, Inc. In light of the Company’s entry into such agreement, it abandoned its previously contemplated spin-off. On October 17, 2014, the Company completed the final sale of a portfolio consisting of 64 multi-tenant properties and seven single-tenant properties (the “Multi-Tenant Portfolio”) to the Purchaser, as discussed in Note 24 — Subsequent Events.
	The Company has classified and accounted for the Multi-Tenant Portfolio’s assets and liabilities as held for sale as of September 30, 2014. As the sale does not represent a change in strategic direction for the Company and will not have a significant effect on the operations or financial results of the Company, the operating results of the Multi-Tenant Portfolio are not classified as discontinued operations for any periods presented. However, the Company has determined that the Multi-Tenant Portfolio is an individually significant component of the Company. As of December 31, 2013, the Company classified one property as held for sale, which has been presented as discontinued operations on the Company’s consolidated statements of operations.
	The following table summarizes the operating income from continued operations of the Multi-Tenant Portfolio for the three and nine months ended September 30, 2014 and 2013 (in thousands):

	On September 30, 2014, the Company entered into the Purchase Agreement to sell Cole Capital to RCAP , and, in conjunction with the sale agreement, entered into sub-advisory agreements to provide acquisition and property management services to Cole Capital subsequent to the closing of the transaction. Subsequent to September 30, 2014, the Purchase Agreement and sub-advisory agreements were terminated by RCAP as discussed within Note 24 — Subsequent Events. The Company has included the Cole Capital segment in continuing operations as the sale of Cole Capital is not deemed probable within one year as evidenced by the significant changes to the plan that were made.

Income_Taxes

Income Taxes	9 Months Ended
	Sep. 30, 2014
Income Tax Disclosure [Abstract]
Income Taxes	Note 23 — Income Taxes
	As a REIT, the General Partner generally is not subject to federal income tax, with the exception of its TRS. However, the General Partner, including its TRS, and the Operating Partnership are still subject to certain state and local income taxes in the various jurisdictions in which they operate.
	Based on the above, Cole Capital’s business, substantially all of which is conducted through a TRS, recognized a provision for federal and state income taxes of $1.1 million and a benefit of $12.6 million for the three and nine months ended September 30, 2014, respectively, which is included in other income, net in the accompanying consolidated statement of operations. No provision or benefit for income taxes was recognized for the three and nine months ended September 30, 2013 as the Company did not commence operations for Cole Capital until the Cole Acquisition Date. The difference in the benefit from income taxes reflected in the consolidated statements of operations as compared to the benefit calculated at the statutory federal income tax rate is primarily attributable to various permanent differences and state and local income taxes.
	The REI segment recognized state income and franchise tax expense of $2.0 million and $5.9 million during the three and nine months ended September 30, 2014, respectively, and $0.1 million and $0.4 million during the three and nine months ended September 30, 2013, respectively, which are included in other income, net in the accompanying consolidated statements of operations.
	The Company had no unrecognized tax benefits as of or during the nine months ended September 30, 2014 and 2013. Any interest and penalties related to unrecognized tax benefits would be recognized within the provision for income taxes in the accompanying consolidated statements of operations. The Company files income tax returns in the U.S. federal jurisdiction, as well as various state jurisdictions, and is subject to routine examinations by the respective tax authorities. With few exceptions, the Company is no longer subject to federal or state examinations by tax authorities for years before 2010.

	Executive Leadership Changes and Audit Committee Investigation
	On September 30, 2014, the Company issued a press release announcing that, effective October 1, 2014, as previously communicated through its stockholder letters, David S. Kay would become Chief Executive Officer of the Company and Lisa E. Beeson would become the Company’s President. Nicholas S. Schorsch, who had served as the Company’s Chief Executive Officer, would remain the Company’s Executive Chairman.
	On October 29, 2014, the Company filed a Current Report on Form 8-K with the SEC disclosing the Company’s conclusion that the previously issued consolidated financial statements and other financial information contained in the Company’s Annual Report for the fiscal year ended December 31, 2013 and the Quarterly Reports on Form 10-Q for the fiscal periods ended March 31, 2014 and June 30, 2014, and the Company’s earnings releases and other financial communications for these periods, should no longer be relied upon. Results of the investigation are further discussed within Note 2 — Restatement of Previously Issued Consolidated Financial Statements.
	On October 28, 2014, Brian S. Block and Lisa Pavelka McAlister, the Company’s Executive Vice President, Chief Financial Officer, Treasurer and Secretary and Senior Vice President and Chief Accounting Officer, respectively, each resigned from the Company. The Company’s board of directors appointed Michael Sodo to serve as the Company’s Chief Financial Officer and Gavin Brandon to serve as the Company’s Chief Accounting Officer.
	On December 12, 2014, Nicholas S. Schorsch resigned as Executive Chairman and a director of the Company. He also resigned from all other employment and board positions that he held at the Company and its subsidiaries and certain Company-related entities (including the non-traded real estate investment trusts sponsored or managed by the Company or its affiliates).
	On December 15, 2014, David S. Kay resigned as Chief Executive Officer (“CEO”) and a director of the Company and as CEO of the OP. Lisa E. Beeson also resigned as President and Chief Operating Officer of the Company and the Partnership. In addition, each of them resigned from any other employment or board positions held with the Company, its subsidiaries and certain Company-related entities (including the non-traded real estate investment trusts sponsored or managed by the Company or its affiliates).
	Effective December 15, 2014, William G. Stanley, who had been serving as the Company’s Lead Independent Director, became the Company’s Interim Chief Executive Officer and Interim Chairman of the Company’s board of directors simultaneously resigning from his role as Lead Independent Director. Mr. Stanley will lead the Company until permanent replacements are named. The Compensation Committee of the Company’s board of directors has commenced a search for a new Chief Executive Officer and a new Chairman of the Company’s board of directors.
	Unconsummated Sale of Cole Capital to RCAP
	On October 1, 2014, the Company announced that it had entered into the Purchase Agreement, pursuant to which RCAP would acquire Cole Capital, the Company’s private capital management business, for at least $700.0 million. As part of the transaction, the Company would be entitled to an earn-out of up to an additional $130.0 million based upon Cole Capital’s 2015 EBITDA.
	On November 3, 2014, the Company received notice from RCAP purporting to terminate the Agreement.
	On December 4, 2014, the Company issued a press release announcing that it had entered into a settlement agreement with RCAP that resolved their dispute relating to the Agreement. The settlement, in which the Company received $60.0 million, resolved litigation brought by the Company in the Delaware Court of Chancery to enforce its rights under the Agreement.
	The settlement included: $42.7 million in cash paid by RCAP to the Company; a $15.3 million unsecured note issued by RCAP to the Company; and a release of the Company from its obligation to pay $2.0 million to RCAP or its affiliates relating to another matter described in the press release. The $42.7 million in cash included a $10.0 million payment already delivered to the Company by RCAP in connection with the Agreement. The two-year unsecured note bears interest at an 8.0% interest rate per annum. In addition, the Company and RCAP have agreed to terminate, unwind or otherwise discontinue all agreements, arrangements and understandings between the two parties and any of their respective subsidiaries.
	Multi-tenant Shopping Center Portfolio Sale
	On October 17, 2014, the Company completed the sale of its Multi-Tenant Portfolio for $1.9 billion to the Joint Venture Blackstone and DDR. Additionally, the Company entered into a letter of intent with an unrelated third party to sell five multi-tenant properties for $52.8 million bringing total sale proceeds to $2.0 billion. The transaction aimed to simplify the Company’s business model, allowing it to focus solely on its single-tenant, net lease investments. The disposition to Blackstone and DDR provided $1.3 billion of net proceeds, of which $1.2 billion were used to reduce the Company’s leverage by paying down the Company’s line of credit. In connection with the sale, $542.8 million of secured mortgage debt was either repaid or assumed by the Purchaser, providing the Company with $1.3 billion in net proceeds and a loss on sale of $261.1 million, which includes the write-off of $195.5 million of goodwill allocated to the cost basis of the Multi-Tenant Portfolio.
	Line of Credit, Agreements, and Waivers
	The Company has substantial amounts of indebtedness outstanding upon which it relies for funding of future capital needs. As discussed within Note 14 — Credit Facilities, at September 30, 2014, the Credit Facility had commitments of $4.3 billion. As of September 30, 2014, a maximum of $391.0 million was available to the OP for future borrowings, subject to borrowing availability.
	On November 12, 2014, the Company entered into a consent, waiver and amendment (“the Amendment”) with its lenders under its unsecured credit facility for an extension regarding the delivery of its third quarter 2014 financial statements and certain other financial deliverables until the earlier of five days following the date the Company files with the SEC its third quarter 2014 10-Q and January 5, 2015. The Amendment allowed the Company to remain compliant with its borrowing obligations under its Credit Facility as its external auditors completed their review of the Company’s previously filed 2013 and 2014 financial statements. As part of the Amendment, in order to better align the size of the facility with anticipated future usage, the Company elected to reduce the maximum amount of indebtedness from $4.65 billion to $4.0 billion. Additionally, until the 2013 and 2014 financial statements are filed with the SEC, the maximum principal amount of indebtedness outstanding under the Credit Facility was temporarily reduced thereunder to $3.6 billion.
	On December 23, 2014, the Company and the OP, as the borrower, entered into a Consent and Waiver Agreement (the “Consent and Waiver”) with respect to Amended Credit Agreement. The Consent and Waiver, among other things, (i) provided for a further extension regarding the delivery of the Company’s third quarter 2014 financial statements and certain other financial deliverables that the Company agreed to provide under the Amendment, until the earlier of: March 2, 2015; and 45 days following the receipt of a notice of breach or default from the applicable trustee or the requisite percentage of holders under the Company’s and the OP’s respective indentures, (ii) provided an extension from the lenders for the delivery of the Company’s full-year 2014 audited financial statements until the earlier of: the fifth day after the date that the Company files its Annual Report on Form 10-K with the SEC for the fiscal year ended December 31, 2014; and March 31, 2015, (iii) permanently reduced the maximum amount of indebtedness under the Credit Agreement to $3.6 billion, including the reduction of commitments under the Company’s revolving facilities and the elimination of the $25 million swingline facility, (iv) provided that until the date that all required financial deliverables have been delivered, no further loans or letters of credit would be requested under the Amended Credit Agreement by the Company, other than in accordance with the cash flow forecast provided by the Company to the Lenders thereunder, that neither the Company nor the OP would pay any dividends on, or make any other Restricted Payment (as defined in the Credit Agreement) on, its respective common equity and (v) provided that the Company would provide additional financial and other information to the Lenders from time to time. In connection with the Amendment and Consent and Waiver, the Company agreed to pay certain customary fees to the consenting Lenders and agreed to reimburse certain customary expenses of the arrangers. On February 20, 2015, we entered into a third consent (the “Third Consent”) to confirm that certain revisions to the required financial deliverables were agreed with the Lenders.
	Agreement in Principle with Senior Noteholder Group; Convertible Notes
	On January 22, 2015, the Company announced that it had entered into an agreement in principle with an ad hoc group of holders (the “Senior Noteholder Group”), which the Company had been advised then represented a majority of the aggregate principal amounts outstanding of each of the 2.00% senior notes due 2017, the 3.00% senior notes due 2019 and the 4.60% senior notes due 2024, which, in each case, were issued by the OP, of which the Company is the sole general partner, and guaranteed by us under an Indenture, dated February 6, 2014 (the “Indenture”), by and among the OP, U.S. Bank National Association, as trustee, and the guarantors named therein. Pursuant to such agreement, the Senior Noteholder Group agreed not to issue a notice of default, prior to March 3, 2015, for the Company’s failure to timely deliver this quarterly report on Form 10-Q containing financial information required to be included therein in respect of the OP, which is required to be delivered pursuant to the terms of the Indenture. In exchange, the Company agreed to sign a confidentiality agreement with the Senior Noteholder Group’s counsel and pay reasonable and documented fees and out-of-pocket expenses of such counsel up to $300,000. Furthermore, the parties agreed that in the event a notice of default related to our failure to timely deliver such this quarterly report on Form 10-Q is issued by the senior noteholders on or after March 3, 2015, the 60-day cure period set forth in the Indenture will be reduced by one day for each day after January 19, 2015 that such notice of default is given. Such agreement was subsequently definitively documented and a supplement to the Indenture was entered into on February 9, 2015. The agreement was reached after the ad hoc group organized recently and directed counsel to the Senior Noteholder Group to engage in discussions with the Company regarding the terms of a possible resolution in response to our failure to timely deliver such third quarter 2014 financial information regarding the OP.
	In addition, the Company announced on January 22, 2015 that it received at its Phoenix, Arizona corporate office notice (the “Notice”) from the trustee under the indentures (the “Convertible Indentures”) governing each of the 3.00% convertible senior notes due 2018 issued by us on July 29, 2013 and the 3.75% convertible senior notes due 2020 issued by the Company on December 10, 2013 (collectively, the “Convertible Notes”) of the Company’s failure to timely deliver our Third Quarter 10-Q, which was required to be delivered pursuant to the terms of the Convertible Indentures. Subsequent to the Company’s announcement, the Company learned that it also received the Notice on January 16, 2015, at an address in New York City that was formerly the Company’s principal place of business. Pursuant to the terms of the Convertible Indentures, the Company has 60 days following its receipt of a notice of default to deliver the required financial statements, after which such failure would become an event of default under each of the Convertible Indentures. The filing of this quarterly report on Form 10-Q will cure such default.
	Non-Compliance Associated with the Company’s and the Partnership’s Filings
	The federal securities laws require companies subject to the Exchange Act to disclose information on an ongoing basis. These laws include deadlines for public companies based on the category of the filer as well as type of form filed.
	The Company is classified as a Large Accelerated Filer. The deadlines associated with our filing category are as follows:
		•		The Company’s Annual Report on Form 10-K must be submitted within 60 days of the Company’s fiscal year end; and
		•		The Company’s Quarterly Report on Form 10-Q must be submitted within 40 days of the Company’s fiscal quarter end.
		•		The Partnership is a non-accelerated filer and its filing deadlines are 90 and 45 days, respectively.
	In light of the non-reliance on the Company’s and the Partnership’s financial statements and the ongoing Audit Committee investigation, such deadlines with the SEC were not met with respect to the Company’s or the Partnership’s Quarterly Report on Form 10-Q for the three months ended September 30, 2014.
	On November 12, 2014, the Company received a notification letter (the “Letter”) from the NASDAQ Listing Qualifications Department (“NASDAQ”) stating that because the Company had not yet filed its Quarterly Report on Form 10-Q for the period ended September 30, 2014 (the “Third Quarter 10-Q”) with the SEC, it was not in compliance with the continued listing requirements under NASDAQ Listing Rule 5250(c)(1). The Company also received, and has cooperated with, a letter (the “NASDAQ Information Request”) from NASDAQ requesting certain information relating to the matters described in the Current Report on Form 8-K filed October 29, 2014.
	Pursuant to the Letter, the Company was required to submit a plan to NASDAQ to regain compliance with the applicable NASDAQ Listing Rule within 60 days of November 12, 2014. We complied and submitted a plan. After review of the Company’s plan for regaining compliance, NASDAQ granted the Company an extension until April 15, 2015 to deliver our Third Quarter 10-Q and any other delinquent filings to regain compliance with the listing rule.
	Dividend Policy
	As of December 24, 2014, the Company determined that, until it has delivered its 2013 financial statements, 2014 financial statements and related compliance certificates, neither it nor its subsidiary, the OP, will pay any dividends on, or make any other Restricted Payment (as defined in the Amended Credit Agreement) on, its respective common equity. Following the delivery of its financial statements, the Company will reevaluate a reinstatement of its dividend at a rate that is in line with its industry peers.
	Cole Litigation Matters
	The defendants in the consolidated Baltimore Merger Actions, which were filed by Cole stockholders challenging the Cole Merger, mailed a Notice of Pendency of Derivative and Class Action (the “Class Notice”) to the Cole stockholders on October 7, 2014, following the court’s preliminary approval of the parties’ Settlement Stipulation. On December 3, 2014, the parties in the consolidated Baltimore Merger Actions executed an Amended Stipulation and Release and Agreement of Compromise and Settlement (the “Amended Stipulation”) modifying the Stipulation. A final settlement hearing in the consolidated Baltimore Merger Actions was held on December 12, 2014, and on January 13, 2015, the Baltimore Circuit Court issued an order approving the settlement pursuant to the terms of the Amended Stipulation. Two objectors have since filed a notice of appeal of the settlement order. Following court approval of the settlement of the consolidated Baltimore Merger Actions, the Wunsch case was dismissed voluntarily on January 21, 2015.
	Regulatory Investigations and Litigation Relating to the Audit Committee Investigation
	On October 29, 2014, the Company filed a Current Report on Form 8-K (the “October 29 8-K”) reporting that the Audit Committee had concluded that the previously-issued audited consolidated financial statements and other financial information contained in the original filing of the Company’s Annual Report on Form 10-K for the year ended December 31, 2013, the previously issued unaudited financial statements and other financial information contained in the Company’s Quarterly Reports on Form 10-Q for the fiscal periods ended March 31, 2014 and June 30, 2014, and the Company’s earnings releases and other financial communications for these periods should no longer be relied upon. Prior to that filing, the Audit Committee previewed for the SEC the information contained in that filing. Subsequent to the filing, the SEC provided notice that it had commenced a formal investigation and issued subpoenas calling for the production of documents. In addition, the United States Attorney’s Office for the Southern District of New York contacted counsel for the Audit Committee and counsel for the Company with respect to this matter, and the Secretary of the Commonwealth of Massachusetts issued a subpoena calling for the production of various documents. The Audit Committee and the Company are cooperating with these regulators in their investigations.
	As discussed below, the Company and certain of its current and former directors and officers have been named as defendants in a number of lawsuits filed in response to the October 29 8-K, including class action, derivative actions, and individual actions under the federal securities laws and state common and corporate laws in both federal and state courts in New York and Maryland.
	Between October 30, 2014 and January 20, 2015, the Company and its current and former officers and directors, among others, were named as defendants in ten putative securities class action complaints in the United States District Court for the Southern District of New York (the “SDNY Actions”): Ciraulu v. American Realty Capital, Inc., et al., No. 14-cv-8659 (AKH); Priever v. American Realty Capital Properties, Inc., et al., No. 14-cv-8668 (AKH); Rubinstein v. American Realty Capital Properties, Inc., et al., No. 14-cv-8669 (AKH); Patton v. American Realty Capital Properties, Inc., et al., No. 14-cv-8671 (AKH); Edwards v. American Realty Capital Properties, Inc., et al., No. 14-cv-8721 (AKH); Harris v. American Realty Capital Properties, Inc., et al., No. 14-cv-8740 (AKH); Abadi v. American Realty Capital Properties, Inc., et al., No. 14-cv-9006 (AKH); City of Tampa General Employees Retirement Fund v. American Realty Capital Properties, Inc., et al., No. 14-cv-10134 (AKH); Teachers Insurance and Annuity Association of America v. American Realty Capital Properties, Inc., et al., No. 15-cv-0421 (AKH); and New York City Employees Retirement System v. American Realty Capital Properties, Inc., et al., No. 15-cv-0422 (AKH). At a February 10, 2015 status conference, the court consolidated the SDNY Actions, appointed a lead plaintiff, and set a deadline of April 10, 2015 for the defendants to respond to the consolidated class action complaint, namely, the complaint filed in Teachers Insurance and Annuity Association of America v. American Realty Capital Properties, Inc., et al., No. 15-cv-0421 (AKH). The consolidated class action complaint asserts claims for violations of Sections 11, 12(a)(2) and 15 of the Securities Act of 1933 and Sections 10(b), 14(a) and 20(a) of the Securities Exchange Act of 1934 and Rules 10b-5 and 14a-9 promulgated thereunder, arising out of allegedly false and misleading statements in connection with the purchase or sale of the Company’s securities. The proposed class period runs from May 6, 2013 to October 29, 2014.
	In addition, on November 25, 2014, the Company and certain of its current and former officers and directors were named as defendants in a putative securities class action filed in the Circuit Court for Baltimore County, Maryland, captioned Wunsch v. American Realty Capital Properties, Inc., et al., No. 03-C-14-012816 (the “Maryland Securities Action,” and together with the SDNY Actions, the “Securities Actions”). On December 23, 2014, the Company removed the Maryland Securities Action to the United States District Court for the District of Maryland (Northern Division), under the caption Wunsch v. American Realty Capital Properties, Inc., et al., No. 14-cv-4007 (ELH), and seeks to transfer the action to the United States District Court for the Southern District of New York. The Maryland Securities Action asserts claims for violations of Sections 11 and 15 of the Securities Act of 1933, arising out of allegedly false and misleading statements made in connection with the Company’s securities issued in connection with the Cole Merger. The Company is not yet required to respond to this complaint.
	Between November 17, 2014 and February 2, 2015, six shareholder derivative actions, purportedly in the name and for the benefit of the Company, were filed against certain of the Company’s current and former officers and directors, amongst others, in the United States District Court for the Southern District of New York (the “SDNY Derivative Actions”): Michelle Graham Turner 1995 Revocable Trust v. Schorsch, et al., No. 14-cv-9140 (AKH); Froehner v. Schorsch, et al., No. 14-cv-9444 (AKH); Serafin v. Schorsch, et al., No. 14-cv-9672 (AKH); Hopkins v. Schorsch, et al., No. 15-cv-262 (AKH); Appolito v. Schorsch, et al., No. 15-cv-644 (AKH); and The Joel and Robin Staadecker Living Trust v. Schorsch, et al., No. 15-cv-768 (AKH). In addition, between December 30, 2014 and January 16, 2015, the Company and certain of its current and former officers and directors were named as defendants in two shareholder derivative actions filed in the Circuit Court for Baltimore City, Maryland (the “Maryland Derivative Actions”): Meloche v. Schorsch, et al., No. 24-C-14-008210 and Botifoll v. Schorsch, et al., No. 24-C-15-000245. In addition, on January 29, 2015, the Company and certain of its current directors, amongst others, were named as defendants in a shareholder derivative action filed in the Supreme Court of the State of New York, captioned Fran Kosky Roth IRA v. Rendell, et al., No. 15-650269 (the “New York Derivative Action,” and together with the SDNY Derivative Actions and the Maryland Derivative Actions, the “Derivative Actions”). On February 9, 2015 and February 20, 2015, three plaintiffs who filed SDNY Derivative Actions—Appolito, Hopkins and The Joel and Robin Staadecker Living Trust—voluntarily dismissed their actions without prejudice. The Derivative Actions seek money damages and other relief on behalf of the Company for, among other things, alleged breaches of fiduciary duty, abuse of control, gross mismanagement and unjust enrichment in connection with the alleged conduct underlying the claims asserted in the Securities Actions and negligence and breach of contract. At a February 10, 2015 status conference, the court consolidated the SDNY Derivative Actions and directed the plaintiffs to file a consolidated amended complaint by March 10, 2015. The court set a deadline of April 3 for the defendants to respond to the consolidated complaint. On February 18, 2015, the parties to the New York Derivative Action entered into a stipulation setting a deadline of April 20, 2015 for the Company and defendants to respond to the complaint in that action. The Company and defendants are not yet required to respond to the complaints in the Maryland Derivative Actions.
	On December 18, 2014, a former employee, Lisa McAlister, filed a defamation action against the Company and certain of its former officers and directors in the Supreme Court for the State of New York, captioned McAlister v. American Realty Capital Properties, Inc., et al., No. 14-162499. The complaint sought, among other things, compensatory and punitive damages and alleged that the October 29 8-K falsely blamed plaintiff for improper accounting and financial reporting practices. On January 26, 2015, the Company and the other defendants filed motions to dismiss plaintiff’s complaint. Subsequently, Ms. McAlister dismissed this action without prejudice.
	On January 7, 2015, Ms. McAlister also filed a complaint, No. 2-4173-15-016, with the Occupational Safety and Health Administration of the United States Department of Labor. The complaint sought, among other things, compensatory and punitive damages and asserted claims for wrongful termination of employment for allegedly reporting concerns relating to alleged improper accounting practices by the Company. Ms. McAlister has withdrawn the complaint without prejudice.
	On January 15, 2015, the Company and certain of its former directors and officers were named as defendants in an individual securities fraud action filed in the United States District Court for the Southern District of New York, captioned Jet Capital Master Fund, L.P. v. American Realty Capital Properties, Inc., et al., No. 15-cv-307 (AKH) (the “Jet Capital Action”). The Jet Capital Action seeks money damages and asserts claims for alleged violations of Sections 10(b), 18 and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder, as well as common law fraud under New York law in connection with the purchase of the Company’s securities. The court set a deadline of April 10 for the defendants to respond to the complaint.
	On February 20, 2015, the Company, certain of its current and former directors and officers, and ARC Properties Operating Partnership L.P. (and others) were named as defendants in an individual securities fraud action filed in the United States District Court for the Southern District of New York, captioned Twin Securities, Inc. v.

The Company and defendants are not yet required to respond to the complaint in the Twin Securities Action.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2014
Accounting Policies [Abstract]
Basis of Accounting, Principles of Consolidation and Basis of Presentation	The consolidated financial statements of the Company included herein include the accounts of ARCP and its consolidated subsidiaries, including the Operating Partnership. All intercompany amounts have been eliminated. The financial statements were prepared in conformity with U.S. GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The information furnished includes all adjustments and accruals of a normal recurring nature, which, in the opinion of management, are necessary for a fair presentation of results for the interim periods. The results of operations for the three and nine months ended September 30, 2014 are not necessarily indicative of the results for the entire year or any subsequent interim period.
	These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2013 of the Company, which are included in the Amended 10-K. There have been no significant changes to these policies during the nine months ended September 30, 2014, other than the updates described below.
	Principles of Consolidation and Basis of Presentation
	The consolidated financial statements include the accounts of the Company, consolidated joint venture arrangements and its subsidiaries. The portions of the consolidated joint venture arrangements not owned by the Company are presented as non-controlling interests. In addition, as described in Note 1 — Organization, certain affiliates and non-affiliated third parties have been issued OP Units. Holders of OP Units are considered to be non-controlling interest holders in the OP and their ownership interest is reflected as equity in the consolidated balance sheets. In addition, a portion of the earnings and losses of the OP are allocated to non-controlling interest holders based on their respective ownership percentages. Upon conversion of OP Units to common stock, any difference between the fair value of common shares issued and the carrying value of the OP Units converted is recorded as a component of equity. As of September 30, 2014 and December 31, 2013, there were 24,690,496 and 9,591,173 OP Units outstanding, respectively. In addition, as discussed in Note 3 —Mergers and Acquisitions, the historical information of ARCT III and ARCT IV has been presented as if the mergers had occurred as of the beginning of the earliest period presented.
	The Company evaluates its relationships and investments to determine if it has variable interests. A variable interest is an investment or other interest that will absorb portions of an entity’s expected losses or receive portions of the entity’s expected residual returns. The Company’s evaluation includes consideration of the qualitative and quantitative significance of fees it earns from certain of its relationships and investments. If the Company determines that it has a variable interest in an entity, it evaluates whether such interest is in a variable interest entity (“VIE”). A VIE is broadly defined as an entity where either (1) the equity investors as a group, if any, lack the power through voting or similar rights to direct the activities of an entity that most significantly impact the entity’s economic performance or (2) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support.
	A variable interest holder is considered to be the primary beneficiary of a VIE if it has the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and has the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to the VIE. The Company qualitatively assesses whether it is (or is not) the primary beneficiary of a VIE. Consideration of various factors include, but are not limited to, the Company’s ability to direct the activities that most significantly impact the entity’s economic performance, its form of ownership interest, its representation on the entity’s governing body, the size and seniority of its investment, its ability and the rights of other investors to participate in policy making decisions and to replace the manager of and/or liquidate the entity. The Company consolidates any VIEs when it is determined to be the primary beneficiary of the VIE’s operations and the difference between consolidating the VIE and accounting for it on the equity method would be material to the Company’s financial statements.
	The Company continually evaluates the need to consolidate joint ventures and the managed investment programs based on standards set forth in GAAP as described above.
Investment in Unconsolidated Entities	Investment in Unconsolidated Entities
	Investment in Unconsolidated Joint Ventures
	Investment in unconsolidated joint ventures as of September 30, 2014 consisted of the Company’s interest in six joint ventures that owned six properties (the “Unconsolidated Joint Ventures”). As of September 30, 2014, the Company owned aggregate equity investments of $96.4 million in the Unconsolidated Joint Ventures. The Company accounts for the Unconsolidated Joint Ventures using the equity method of accounting as the Company has the ability to exercise significant influence, but not control, over operating and financial policies of these investments. The equity method of accounting requires the investment to be initially recorded at cost and subsequently adjusted for the Company’s share of equity in the joint ventures’ earnings and distributions. The Company records its proportionate share of net income from the Unconsolidated Joint Ventures within the Other income, net line item in the consolidated statement of operations. During the three and nine months ended September 30, 2014, the Company recognized $0.2 million and $1.6 million, respectively, of net income from the Unconsolidated Joint Ventures. The Company did not recognize any net income from the Unconsolidated Joint Ventures during the three and nine months ended September 30, 2013.
	Investment in Managed REITs
	As of September 30, 2014, the Company owned aggregate equity investments of $4.4 million in the following publicly registered, non-traded REITs: Cole Credit Property Trust IV, Inc. (“CCPT IV”); Cole Corporate Income Trust, Inc. (“CCIT”); Cole Real Estate Income Strategy (Daily NAV), Inc. (“INAV”); Cole Office & Industrial REIT (CCIT II), Inc. (“CCIT II”); and Cole Credit Property Trust V, Inc. (“CCPT V,” and collectively with CCPT IV, CCIT, INAV and CCIT II, the “Managed REITs”). Prior to the CCPT Acquisition Date, CCPT was a Managed REIT and accounted for using the equity method. As of the CCPT Acquisition Date, the Company had an approximate $5,000 equity investment in CCPT. The Company accounts for these investments using the equity method of accounting which requires the investment to be initially recorded at cost and subsequently adjusted for the Company’s share of equity in the respective Managed REIT’s earnings and distributions. The Company records its proportionate share of net income from the Managed REITs within the Other income, net line item in the consolidated statement of operations. During the three and nine months ended September 30, 2014, the Company recognized $0.4 million of net income and $1.4 million of net loss, respectively, from the Managed REITs. The Company did not recognize any net income from the Managed REITs during the three and nine months ended September 30, 2013.
Leasehold Improvements and Property and Equipment	Leasehold Improvements and Property and Equipment
	The Company leases its office facilities under operating leases. Leasehold improvements related to these are recorded at cost less accumulated amortization. Leasehold improvements are amortized over the lesser of the estimated useful life or remaining lease term.
	Property and equipment, which primarily include office furniture, fixtures and equipment and computer hardware and software, are stated at cost less accumulated depreciation. Property and equipment are depreciated on a straight-line method over the estimated useful lives of the assets, which range from five to seven years. The Company reassesses the useful lives of its property and equipment and adjusts the future monthly depreciation expense based on the new useful life, as applicable. If the Company disposes of an asset, the asset and related accumulated depreciation are written off upon disposal.
	Investment in Unconsolidated Entities
	The Company is required to determine whether an event or change in circumstances has occurred that may have a significant adverse effect on the fair value of any of its investment in the unconsolidated entities. If an event or change in circumstance has occurred, the Company is required to evaluate its investment in the unconsolidated entity for potential impairment and determine if the carrying amount of its investment exceeds its fair value. An impairment charge is recorded when an impairment is deemed to be other-than-temporary. To determine whether an impairment is other-than-temporary, the Company considers whether it has the ability and intent to hold the investment until the carrying amount is fully recovered. The evaluation of an investment in an unconsolidated entity for potential impairment requires the Company’s management to exercise significant judgment and to make certain assumptions. The use of different judgments and assumptions could result in different conclusions. No impairments of unconsolidated entities were identified during the nine months ended September 30, 2014.
	Leasehold Improvements and Property and Equipment
	Leasehold improvements and property and equipment are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. If this review indicates that the carrying amount of the asset is not recoverable, the Company records an impairment loss, measured at fair value by estimated discounted cash flows or market appraisals. The evaluation of an investment in a property for potential impairment requires the Company’s management to exercise significant judgment and to make certain assumptions. The use of different judgments and assumptions could result in different conclusions. The Company identified properties during the three and nine months ended September 30, 2014 and 2013 with impairment indicators for which the undiscounted future cash flows expected as a result of the use and eventual disposition of the real estate and related assets was less than the carrying amount of each respective properties, as discussed in Note 11 — Fair Value of Financial Instruments.
	In addition to the properties discussed in Note 11 — Fair Value of Financial Instruments, as of September 30, 2014, the Company noted potential impairment indicators at certain properties with an aggregate carrying value of $145.5 million. However, the Company’s estimate of undiscounted cash flows indicated that such carrying amounts were expected to be recovered as of September 30, 2014. Nonetheless, it is reasonably possible that the estimate of undiscounted cash flows may change in the near term, which will result in the need to record an impairment loss to reduce such assets to fair value. Any such impairment losses may have a material impact on the Company’s assets and stockholder’s equity, operating and net loss and comprehensive loss. The evaluation of properties for potential impairment requires the Company’s management to exercise significant judgment and to make certain assumptions. The use of different judgments and assumptions could result in different conclusions.

No impairments of unconsolidated entities were identified during the nine months ended September 30, 2014.
Goodwill	Goodwill
	In the case of a business combination, after identifying all tangible and intangible assets and liabilities, the excess consideration paid over the fair value of the assets and liabilities acquired and assumed, respectively, represents goodwill. Goodwill that arose as a result of the Company’s mergers and acquisitions was recorded in the Company’s consolidated financial statements.
	In the event the Company disposes of a property that constitutes a business under U.S. GAAP from a reporting unit with goodwill, the Company will allocate a portion of the reporting unit’s goodwill to that business in determining the gain or loss on the disposal of the business. The amount of goodwill allocated to the business will be based on the relative fair value of the business to the fair value of the reporting unit. The REI segment and Cole Capital each comprise one reporting unit.
	The Company will evaluate goodwill for impairment annually or more frequently when an event occurs or circumstances change that indicate the carrying value, by reporting unit, may not be recoverable. The Company’s annual testing date is during the fourth quarter. The Company will test goodwill for impairment by first comparing the book value of net assets to the fair value of each reporting unit. If the fair value is determined to be less than the book value or if qualitative factors indicate that it is more likely than not that goodwill is impaired, a second step is performed to compute the amount of impairment as the difference between the estimated fair value of goodwill and the carrying value. The Company will estimate the fair value of the reporting units using discounted cash flows and relevant competitor multiples. The evaluation of goodwill for potential impairment requires the Company’s management to exercise significant judgment and to make certain assumptions. The use of different judgments and assumptions could result in different conclusions. In conjunction with the disposition of the Multi-Tenant Portfolio, as defined in Note 22 — Property Dispositions, the Company evaluated the remaining portion of goodwill assigned to the REI segment for impairment. The fair value of the REI segment was determined to be greater than the book value of its net assets. As such, no goodwill impairment was recorded during the nine months ended September 30, 2014.
	Subsequent to September 30, 2014, the Company noted potential impairment indicators of goodwill such that it is reasonably possible that the estimate of the fair value of each reporting unit may change in the near term, which will result in the need to record an impairment loss to reduce goodwill to fair value. Any such impairment losses may have a material impact on the Company’s assets and stockholder’s equity, operating and net loss and comprehensive loss.
	The following summarizes the Company’s goodwill activity during the nine months ended September 30, 2014 by segment (in thousands):
			REI Segment			Cole Capital			Consolidated
	Balance as of January 1, 2014		$	92,789		$	—		$	92,789
	Cole Merger (1)			1,654,085			558,835			2,212,920
	Goodwill allocated to dispositions (2)			(209,259	)		—			(209,259	)
	Balance as of September 30, 2014		$	1,537,615		$	558,835		$	2,096,450
	-1	Goodwill recognized from the Cole Merger was assigned to the REI segment and Cole Capital based on the excess consideration paid over the fair value of the assets and liabilities acquired and assumed in each segment. Refer to Note 5 — Acquisitions of CapLease, Cole and CCPT for further discussion.
	-2	Goodwill allocated to the cost basis of properties sold or classified as held for sale is included in loss on held for sale assets and disposition of properties, net, in the consolidated statement of operations.
Program Development Costs	Program Development Costs
	The Company pays for organization, registration and offering expenses associated with the sale of common stock of the Managed REITs. The reimbursement of these expenses by the Managed REITs is limited to a certain percentage of the proceeds raised from their offerings, in accordance with their respective advisory agreements and charters. Such expenses paid by the Company on behalf of the Managed REITs in excess of these limits that are expected to be collected are recorded as program development costs. The Company assesses the collectability of the program development costs, considering the offering period and historical and forecasted sales of shares under the Managed REITs’ respective offerings and reserves for any balances considered not collectible. No reserves were recorded as of September 30, 2014, as the Company expects to be reimbursed for all of the program development costs by the Managed REITs as additional proceeds from their respective offerings are raised. Program development costs are included in deferred costs and other assets, net in the accompanying consolidated balance sheets.
Acquisition Related Expenses and Merger and Other Non-routine Transaction Related Expenses	Acquisition Related Expenses and Merger and Other Non-routine Transaction Related Expenses
	All direct costs incurred as a result of a business combination are classified as acquisition costs or merger and other non-routine transaction costs and expensed as incurred. In addition, indirect costs, such as internal salaries, that are tracked and documented in a manner that clearly indicate that the activities driving the cost directly relate to activities necessary to complete, or effect, a business combination are classified as acquisition related expenses. Similar costs incurred in relation to mergers with entities under common control (which are not accounted for as acquisitions) are included in the caption “merger and other non-routine transactions.” Acquisition related expenses include legal and other transaction related costs incurred in connection with self-originated acquisitions including purchases of portfolios. Other non-routine transaction costs are also presented within the line item merger and other non-routine transactions in the consolidated statements of operations.
	Merger and other non-routine transaction related expenses include the following costs (amounts in thousands):

Due from Affiliates	Due from Affiliates
	The Company receives or may be entitled to receive compensation and reimbursement for services primarily relating to the Managed REITs’ offerings and the investment, management, financing and disposition of their respective assets. Refer to Note 20 — Related Party Transactions and Arrangements for further explanation.
Reportable Segments	Reportable Segments
	The Company has concluded that it has two reportable segments as it has organized its operations into two segments for management and internal financial reporting purposes, REI and Cole Capital. The identification and aggregation of reportable segments requires the Company’s management to exercise certain judgments. Refer to Note 6 — Segment Reporting for further information.
Revenue Recognition - Cole Capital	Revenue Recognition - Cole Capital
	Revenue consists of securities sales commissions and dealer manager fees, real estate acquisition fees, property management fees, advisory fees, asset management fees and performance fees for services relating to the Managed REITs’ offerings and the investment and management of their respective assets, in accordance with the respective advisory and dealer manager agreements. The Company records revenue related to acquisition fees, securities sales commissions and dealer manager fees upon completion of a transaction and advisory, asset and property management fees as services are performed. The Company is also reimbursed for certain costs incurred in providing these services. Securities sales commission and dealer manager reimbursements are recorded as revenue as the expenses are incurred. Other reimbursements are recorded as revenue when reimbursements are reasonably assured.
Income Taxes	Income Taxes
	ARCP currently qualifies and has elected to be taxed as a REIT for federal income tax purposes under Sections 856 through 860 of the Internal Revenue Code. As a REIT, except as discussed below, ARCP generally is not subject to federal income tax on taxable income that it distributes to its stockholders so long as it distributes at least 90% of its annual taxable income (computed without regard to the dividends paid deduction and excluding net capital gains). REITs are subject to a number of other organizational and operational requirements. Even if ARCP maintains its qualification for taxation as a REIT, it may be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed income.
	The Operating Partnership is classified as a partnership for federal income tax purposes. As a partnership, the Operating Partnership is not a taxable entity for federal income tax purposes. Instead, each partner in the Operating Partnership is required to take into account its allocable share of the Operating Partnership’s income, gains, losses, deductions, and credits for each taxable year. However, the Operating Partnership may be subject to certain state and local taxes on its income and property.
	As of September 30, 2014, the Operating Partnership, ARCP, ARCT III and ARCT IV had no material uncertain income tax positions. The tax years subsequent to and including the fiscal year ended December 31, 2010 remain open to examination by the major taxing jurisdictions to which the Operating Partnership, ARCP, ARCT III and ARCT IV are subject.
	Under the LPA, the Operating Partnership is to conduct business in such a manner as to permit ARCP at all times to qualify as a REIT.
	The Company conducts substantially all of its Cole Capital business operations through a TRS. A TRS is a subsidiary of a REIT that is subject to corporate federal, state and local income taxes, as applicable. The Company’s use of a TRS enables it to engage in certain business activities while complying with the REIT qualification requirements and to retain any income generated by these businesses for reinvestment without the requirement to distribute those earnings. The Company conducts all of its business in the United States, and as a result, it files income tax returns in the U.S. federal jurisdiction and various state and local jurisdictions. Certain of The Company’s inter-company transactions that have been eliminated in consolidation for financial accounting purposes are also subject to taxation.
	The Company provides for income taxes in accordance with current authoritative accounting and tax guidance. The tax expense or benefit related to significant, unusual or extraordinary items is recognized in the quarter in which those items occur. In addition, the effect of changes in enacted tax laws, rates or tax status is recognized in the quarter in which the change occurs. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained or the tax environment changes.
	In conjunction with the acquisition of the Red Lobster Portfolio, the Company entered into a reverse section 1031 like-kind exchange agreement with a third party intermediary. The exchange agreement is for a maximum of 180 days and allows the Company, for tax purposes, to defer gains on the sale of other properties sold within this period. Until the earlier of termination of the exchange agreements or 180 days after the first acquisition date, the third party intermediary is the legal owner of each property, although the Company controls the activities that most significantly impact each property and retains all of the economic benefits and risks associated with each property. Each property is held by the third party intermediary in a variable interest entity for which the Company is the primary beneficiary. Accordingly, the Company consolidates these properties and their operations even during the period they are held by the third party intermediary. As of September 30, 2014, 541 Red Lobster properties acquired in July and September of 2014 were held by the third party intermediary. The Company has consolidated each of these properties since the date of acquisition.
Repurchase Agreements	Repurchase Agreements
	In certain circumstances, the Company may obtain financing through a repurchase agreement. The Company evaluates the initial transfer of a financial instrument and the related repurchase agreement for sale accounting treatment. In instances where the Company maintains effective control over the transferred securities, the Company accounts for the transaction as a secured borrowing, and accordingly, both the securities and related repurchase agreement payable are recorded separately in the accompanying consolidated balance sheets in investment securities, at fair value and other debt, net, respectively. In instances where the Company does not maintain effective control over the transferred securities, the Company accounts for the transaction as a sale of securities for proceeds consisting of cash and a forward purchase contract.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In April 2014, the U.S. Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update, 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 (“ASU 2014-08”), which amends the reporting requirements for discontinued operations by updating the definition of a discontinued operation to be a component of an entity that represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results, resulting in fewer disposals that qualify for discontinued operations reporting yet the pronouncement also requires expanded disclosures for discontinued operations. The Company adopted ASU 2014-08 effective January 1, 2014. Beginning with the first quarter of 2014, the results of operations for all properties sold and properties classified as held for sale that do not meet the criteria to qualify as a discontinued operation and were not previously reported in discontinued operations in the Amended 10-K for the year ended December 31, 2013 are presented within income from continuing operations on the accompanying consolidated statements of income.
	In May 2014, FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which supersedes the revenue recognition requirements in Revenue Recognition (Topic 605), and requires an entity to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and is to be applied retrospectively, with early application not permitted. The Company is currently evaluating the impact of the new standard on its financial statements.
	In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”), which requires management to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. ASU 2014-15 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, with early application permitted. The Company does not believe ASU 2014-15, when effective, will have a material impact on the Company’s consolidated unaudited financial statements because the Company currently does not have any conditions that give rise to substantial doubt about its ability to continue as a going concern.
	In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis (“ASU 2015-02”), which eliminates the deferral of FAS 167 and makes changes to both the variable interest model and the voting model. These changes will require re-evaluation of certain entities for consolidation and will require the Company to revise its documentation regarding the consolidation or deconsolidation of such entities. ASU 2015-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, and is to be applied retrospectively, with early adoption permitted. The Company is currently evaluating the impact of the new standard on its financial statements.
