REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

American Realty Capital Properties, Inc.

We have audited the accompanying consolidated balance sheets of American Realty Capital Properties, Inc. (a Maryland corporation) and subsidiaries (the “Company”) as of December 31, 2012 and 2011, and the related consolidated statements of operations and comprehensive loss, changes in equity, and cash flows for each of the two years in the period ended December 31, 2012 and for the period from December 2, 2010 (date of inception) to December 31, 2010. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of American Realty Capital Properties, Inc. and subsidiaries as of December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the two years in the period ended December 31, 2012 and for the period from December 2, 2010 (date of inception) to December 31, 2010 in conformity with accounting principles generally accepted in the United States of America.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2012

Note 1 — Organization

American Realty Capital Properties, Inc. (the “Company”), is a Maryland corporation incorporated on December 2, 2010 that qualified as a real estate investment trust for U.S. federal income tax purposes beginning in the year ended December 31, 2011. On September 6, 2011, the Company completed its initial public offering (the “IPO”) and its shares of common stock began trading on the NASDAQ Capital Market ("NASDAQ") under the symbol “ARCP” on September 7, 2011.

The Company acquires, owns and operates single-tenant, freestanding commercial real estate properties. The Company has acquired a combination of long-term and medium-term leases and intends to continue to acquire properties with approximately 70% long-term leases and 30% medium-term leases, with an average remaining lease term of 10 to 12 years. The Company considers properties that are leased on a “medium-term” basis to mean properties originally leased long-term (ten years or longer) that currently have a primary remaining lease duration of generally three to eight years, on average. The Company expects this investment strategy to develop growth potential from below market leases. Additionally, the Company owns a portfolio that uniquely combines a portfolio of properties with stable income from high credit quality tenants, with properties that have substantial growth opportunities.

On February 28, 2013, the Company merged with American Realty Capital Trust III, Inc., a Maryland Corporation ("ARCT III"), (see Note 2 — Merger Agreement ).

Prior to the Merger (as defined below) and continuing following the consummation of the Merger, substantially all of the Company's business was and continues to be conducted through ARC Properties Operating Partnership, L.P. (the “OP”), a Delaware limited partnership. The Company is the sole general partner and holder of 99.1% of the equity interest in the OP as of December 31, 2012. ARC Real Estate Partners, LLC (the "Contributor") and certain unaffiliated investors are limited partners and owners of 0.2% and 0.7%, respectively, of the equity interest in the OP. After holding units of limited partner interests in the OP (“OP Units”) for a period of one year, holders of OP Units have the right to convert OP Units for the cash value of a corresponding number of shares of the Company's common stock or, at the option of the OP, a corresponding number of shares of the Company's common stock, as allowed by the limited partnership agreement of the OP. All holders of units of equity ownership in the ARCT III operating partnership converted such units into the same class of equity ownership in the OP immediately upon consummation of the Merger. 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.

The Company has retained ARC Properties Advisors, LLC (the “Manager”), a wholly owned subsidiary of the Sponsor, to manage its affairs on a day to day basis and, as a result, is generally externally managed. Prior to the Merger, the Company had no employees. In connection with the Merger, the Company internalized certain functions performed for it by the Sponsor and its affiliates prior to the Merger, including acquisition, accounting and portfolio management services and, as a result, the Company currently employs individuals performing such functions. ARCT III was externally managed by American Realty Capital Advisors III, LLC (the “ARCT III Advisor”). These affiliated parties, including the Manager, the Sponsor and Realty Capital Securities, LLC (“RCS” or the “Dealer Manager”), an entity which is under common ownership with the Sponsor, have performed services for the Company and ARCT III, in exchange for which they have received compensation, fees and expense reimbursements, and will continue to receive compensation, fees and expense reimbursements for providing on-going investment oversight and management services to the Company.

Formation Transactions

At the completion of the Company's IPO, the Contributor , an affiliate of the Sponsor, contributed to the OP its indirect ownership interests in certain assets of ARC Income Properties, LLC and ARC Income Properties III, LLC (the “Contributed Companies”). Assets contributed included (1) 59 properties that are presently leased to RBS Citizens Bank, N.A. and Citizens Bank of Pennsylvania, or collectively, Citizens Bank, one property presently leased to Community Bank, N.A, or Community Bank, and one property leased to Home Depot U.S.A., Inc., or Home Depot, and (2) two vacant properties. Additionally, the OP assumed certain liabilities of the Contributed Companies, including $30.6 million of unsecured notes payable and $96.2 million of mortgage notes secured by the contributed properties.

Because the contribution was from an affiliate of the Sponsor and deemed to be a transaction between entities under common control, the assets and liabilities were recorded by the Company at the Contributor's carrying amount, or book value, at the time of the contribution. The assets and liabilities of the Contributed Companies are summarized as follows (amounts in thousands):

(2)$82.6 million of mortgage notes payable were refinanced with a new $51.5 million revolving credit facility and the remaining balance was repaid from the proceeds of the Company's IPO concurrently with closing of the IPO.

Note 2— Merger Agreement

On December 14, 2012, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with ARCT III and certain subsidiaries of each company. The Merger Agreement provided for the merger of ARCT III with and into a subsidiary of the Company (the “Merger”). The Merger was consummated on February 28, 2013.

Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, each outstanding share of common stock of ARCT III was converted into the right to receive (i) 0.95 of a share of the Company's common stock, (the "Exchange Ratio") or (ii) $12.00 in cash. In addition, each outstanding unit of equity ownership of 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 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 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 Exchange Ratio, resulting in an additional 140.7 million shares of the Company's common stock outstanding after the exchange.

Upon the consummation of the Merger, American Realty Capital III Special Limited Partnership, LLC, the holder of the special limited partner interest in the American Realty Capital Operating Partnership III (the "ARCT III OP"), was entitled to subordinated distributions of net sales proceeds from ARCT III OP which resulted in the issuance of units of limited partner interests in the ARCT III OP, when after applying the Exchange Ratio, resulting in the issuance of an additional 7.3 million OP Units. The parties have agreed that such OP Units will be subject to a minimum one-year holding period before being exchangeable into the Company's common stock.

Upon consummation of the Merger, the vesting of the shares of the Company's and ARCT III's outstanding restricted stock was accelerated.

In connection with the Merger, the Company also had entered into an agreement with the Sponsor and its affiliates to internalize certain functions performed by them prior to the Merger, at no cost to the Company, including acquisition, accounting and portfolio management services (the “Internalization”). In connection with the Internalization, (i) the Company and its Sponsor terminated the acquisition and capital services agreement dated September 6, 2011, between the parties, which eliminated acquisition and financing fees payable by the Company and (ii) the Manager reduced asset management fees from an annualized 0.50% of the unadjusted book value of all of the Company's assets to 0.50% for up to $3.0 billion of unadjusted book value of assets and 0.40% of unadjusted book value of assets greater than $3.0 billion. In addition, the Company paid $4.1 million for certain furniture, fixtures, equipment, and $1.7 million for other assets and certain costs associated with the Merger. The Company and the Manager are considered entities under common control, as such, the assets acquired from the Manager were recorded by the Company at their carryover basis.

Accounting Treatment of the Merger

The Company and ARCT III, to the Merger date, were considered to be entities under common control. Both entities' advisors were wholly owned subsidiaries of the Sponsor. The Sponsor and its related parties have significant ownership interests in the Company and had significant ownership of ARCT III through the ownership of shares of common stock and other equity interests. In addition, the advisors of both entities were contractually eligible to charge potential fees for their services to both of the companies including asset management fees, incentive fees and other fees and continue to charge fees to the Company. Due to the significance of these fees, the advisors and ultimately the Sponsor is 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 qualifies them as affiliated companies under common control in accordance with generally accepted accounting principals 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 Merger date. In addition, U.S. GAAP requires that we present historical financial information as if the entities were combined for each period presented, therefore all financial statements including the notes thereto are presented combining ARCP and ARCT III historical financial information.

New Credit Facility

On February 14, 2013, ARCT III, through ARCT III OP, its operating partnership, entered into an unsecured credit facility (the "New Credit Facility"), with Wells Fargo Bank, National Association, as administrative agent, RBS Citizens, N.A. and Regions Bank, as syndication agents, and Capital One, N.A. and JP Morgan Chase Bank, N.A., as documentation agents.

Additionally, upon consummation of the Merger, the Company's senior secured revolving credit facility with RBS (the "RBS Facility") of up to $150.0 million was paid off in full and terminated. ARCT III terminated the Senior Facility (as defined in Note 5 - Credit Facilities) agreement with RBS simultaneous with entering into the New Credit Facility.

See Note 5 — Credit Facilities for further description of the New Credit Facility and repayments and terminations of facilities upon the consummation of the Merger.

Note 3 — Summary of Significant Accounting Policies

Basis of Accounting

The accompanying consolidated financial statements are prepared on the accrual basis of accounting in accordance with U.S. GAAP.

Principles of Consolidation and Basis of Presentation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. In determining whether the Company has a controlling financial interest in a joint venture and the requirement to consolidate the accounts of that entity, management considers factors such as ownership interest, authority to make decisions and contractual and substantive participating rights of the other partners or members as well as whether the entity is a variable interest entity for which the Company is the primary beneficiary.

Reclassification

Certain reclassifications have been made to the previously issued historical consolidated financial statements of the Company and ARCT III to conform to this consolidated presentation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Management makes significant estimates regarding revenue recognition, to record investments in real estate, real estate taxes, and derivative financial instruments and hedging activities, as applicable.

Formation Transactions

Upon the effectiveness of the IPO, the Company acquired certain properties from affiliated entities of the Company and, as such, the Company was no longer considered to be in the development stage. The contribution of the properties from affiliates in the initial formation of the Company was accounted for as a reorganization of entities under common control and therefore all assets and liabilities related to the contributed properties were accounted for on the carryover basis of accounting whereby the real estate investments were contributed at amortized cost and all assets and liabilities of the predecessor entities became assets and liabilities of the Company.

Real Estate Investments

The Company records acquired real estate at cost and makes assessments as to the useful lives of depreciable assets. The Company considers the period of future benefit of the asset to determine the appropriate useful lives. Depreciation is computed using a straight-line method over the estimated useful life of 40 years for buildings, five to 15 years for building fixtures and improvements and the remaining lease term for acquired intangible lease assets.

Impairment of Long Lived Assets

Operations related to properties that have been sold or properties that are intended to be sold are presented as discontinued operations in the statement of operations for all periods presented, and properties intended to be sold are designated as “held for sale” on the accompanying consolidated balance sheets.

When circumstances indicate the carrying value of a property may not be recoverable, the Company reviews the asset for impairment. This review is based on an estimate of the future undiscounted cash flows, excluding interest charges, expected to result from the property’s use and eventual disposition. These estimates consider factors such as expected future operating income, market and other applicable trends and residual value, as well as the effects of leasing demand, competition and other factors. If impairment exists, due to the inability to recover the carrying value of a property, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair value of the property for properties to be held and used.

For properties held for sale, the impairment loss is the adjustment to fair value less estimated cost to dispose of the asset. These assessments have a direct impact on net income because recording an impairment loss results in an immediate negative adjustment to net income. At December 31, 2012, and 2011, the Company had one and two, respectively, vacant properties classified as properties held for sale. See Note 17 — Discontinued Operations and Properties Held for Sale.

Allocation of Purchase Price of Acquired Assets

The Company allocates the purchase price of acquired properties to tangible and identifiable intangible assets acquired based on their respective fair values. Tangible assets include land, buildings, equipment and tenant improvements on an as-if vacant basis. The Company utilizes various estimates, processes and information to determine the as-if vacant property value. Estimates of value are made using customary methods, including data from appraisals, comparable sales, discounted cash flow analysis and other methods. Identifiable intangible assets include amounts allocated to acquire leases for above- and below-market lease rates, the value of in-place leases, and the value of customer relationships.

Amounts allocated to land, buildings, equipment and fixtures are based on cost segregation studies performed by independent third-parties or on the Company's analysis of comparable properties in its portfolio. Depreciation is computed using the straight-line method over the estimated lives of forty years for buildings, five to ten years for building equipment and fixtures, and the shorter of the useful life or the remaining lease term for tenant improvements.

The aggregate value of intangible assets related to in-place leases is primarily the difference between the property valued with existing in-place leases adjusted to market rental rates and the property valued as if vacant. Factors considered by the Company in its analysis of the in-place lease intangibles include an estimate of carrying costs during the expected lease-up period for each property, taking into account current market conditions and costs to execute similar leases. In estimating carrying costs, the Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up period, which typically ranges from six to 18 months. The Company also estimates costs to execute similar leases including leasing commissions, legal and other related expenses.

AMERICAN REALTY CAPITAL PROPERTIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2012

Above-market and below-market in-place lease values for owned properties are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between the contractual amounts to be paid pursuant to the in-place leases and management's estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. The capitalized above-market lease intangibles are amortized as a decrease to rental income over the remaining term of the lease. The capitalized below-market lease values will be amortized as an increase to rental income over the remaining term and any fixed rate renewal periods provided within the respective leases. In determining the amortization period for below-market lease intangibles, the Company initially will consider, and periodically evaluate on a quarterly basis, the likelihood that a lessee will execute the renewal option. The likelihood that a lessee will execute the renewal option is determined by taking into consideration the tenant's payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area in which the property is located.

The aggregate value of intangibles assets related to customer relationships is measured based on the Company's evaluation of the specific characteristics of each tenant's lease and the Company's overall relationship with the tenant. Characteristics considered by the Company in determining these values include the nature and extent of the Company's existing business relationships with the tenant, growth prospects for developing new business with the tenant, the tenant's credit quality and expectations of lease renewals, among other factors.

The value of in-place leases is amortized to expense over the initial term of the respective leases, which range primarily from 2 to 20 years. The value of customer relationship intangibles is amortized to expense over the initial term and any renewal periods in the respective leases, but in no event does the amortization period for intangible assets exceed the remaining depreciable life of the building. If a tenant terminates its lease, the unamortized portion of the in-place lease value and customer relationship intangibles is charged to expense.

In making estimates of fair values for purposes of allocating purchase price, the Company utilizes a number of sources, including independent appraisals that may be obtained in connection with the acquisition or financing of the respective property and other market data. The Company also considers information obtained about each property as a result of its pre-acquisition due diligence, as well as subsequent marketing and leasing activities, in estimating the fair value of the tangible and intangible assets acquired and intangible liabilities assumed.

Intangible lease assets of the Company consist of the following as of December 31, 2012 and 2011 (amounts in thousands):

	December 31,
	2012			2011
In-place leases, gross	$	210,959		$	21,777

Cash and Cash Equivalents

Cash and cash equivalents include cash in bank accounts as well as investments in highly-liquid money market funds with original maturities of three months or less.

The Company deposits cash with high quality financial institutions. These deposits are guaranteed by the Federal Deposit Insurance Company (“FDIC”) up to an insurance limit. At December 31, 2012 and 2011, the Company had deposits of $156.9 million and $19.3 million, respectively, of which $154.8 million and $18.5 million were in excess of the amount insured by the FDIC. Although the Company bears risk to amounts in excess of those insured by the FDIC, it does not anticipate any losses as a result.

Restricted Cash

Restricted cash primarily consists of reserves related to lease expirations as well as maintenance, structural, and debt service reserves.

Deferred Costs, Net

Deferred costs, net consists of deferred financing costs net of accumulated amortization, deferred leasing costs net of accumulated amortization and deferred offering costs.

Deferred financing costs represent commitment fees, legal fees, and other costs associated with obtaining commitments for financing. These costs are amortized over the terms of the respective financing agreements using the effective interest method. Unamortized deferred financing costs are expensed when the associated debt is refinanced or repaid before maturity. Costs incurred in seeking financial transactions that do not close are expensed in the period in which it is determined the financing will not close. At December 31, 2012 and 2011, the Company had $15.1 million and $3.1 million, respectively, of deferred financing costs net of accumulated amortization.

Deferred leasing costs, consisting primarily of lease commissions and payments made to assume existing leases, are deferred and amortized over the term of the lease. At December 31, 2012 and 2011, the Company had $0.2 million and $0.3 million, respectively, of deferred leasing costs, net of accumulated amortization.

Deferred offering costs represent professional fees, fees paid to various regulatory agencies, and other costs incurred in connection with registering to sell shares of the Company's common stock. As of December 31, 2012, the Company had $0.1 million of deferred offering costs related to the Company's $500.0 million universal shelf and resale registration statements filed with the SEC in August 2012. As of December 31, 2011, the Company had no deferred offering costs.

Share Repurchase Program

ARCT III's board of directors had adopted a Share Repurchase Program (“SRP”) that enabled stockholders to sell their shares to ARCT III in limited circumstances. The SRP permitted investors to sell their shares back to ARCT III after they had held them for at least one year, subject to the significant conditions and limitations described below.

AMERICAN REALTY CAPITAL PROPERTIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2012

The purchase price per share depended on the length of time investors had held such shares as follows: after one year from the purchase date — the lower of $9.25 or 92.5% of the amount they actually paid for each share; after two years from the purchase date —the lower of $9.50 or 95.0% of the amount they actually paid for each share; after three years from the purchase date — the lower of $9.75 or 97.5% of the amount they actually paid for each share; and after four years from the purchase date — the lower of $10.00 or 100% of the amount they actually paid for each share.

ARCT III was only authorized to repurchase shares pursuant to the SRP up to the value of shares issued under the DRIP and limited the amount spent to repurchase shares in a given quarter to the value of the shares issued under the DRIP in that same quarter.

When a stockholder requested repurchases and the repurchases were approved by ARCT III’s board of directors, it reclassified such obligation from equity to a liability based on the settlement value of the obligation. The following table reflects the number of shares repurchased for the years ended December 31, 2012 and 2011. There were no repurchases requested or fulfilled during the period from October 15, 2010 (“ARCT III's date of inception”) to December 31, 2010.

Year ended December 31,	Number of Requests	Number of Shares	Average Price per Share
2011	1	2,375	$	10.00
2012	73	179,104	9.93
Cumulative repurchase requests as of December 31, 2012 (1)	74	181,479	$	9.93

_____________________________

(1) Includes unfulfilled repurchase requests for 35,180 shares at a average price per share of $9.86, which were approved for repurchase as of December 31, 2012.

Upon the Merger the SRP was terminated.

Distribution Reinvestment Plan

Pursuant to the ARCT III distribution reinvestment plan or ("DRIP"), stockholders could have elected to reinvest distributions by purchasing shares of ARCT III common stock in lieu of receiving cash.  No dealer manager fees or selling commissions were paid with respect to shares purchased pursuant to the DRIP.  Participants purchasing shares pursuant to the DRIP had the same rights and were treated in the same manner as if such shares were issued pursuant to ARCT III's initial public offering (the "ARCT III IPO"). Shares issued under the DRIP were recorded within stockholders’ equity in the accompanying consolidated balance sheets in the period distributions were declared. During the years ended December 31, 2012 and 2011, ARCT III issued 2.7 million and 27,169 shares of common stock, respectively, with a value of $26.8 million and $0.3 million, respectively, in each case with a par value per share of $0.01, pursuant to the DRIP. Upon the Merger, the DRIP was terminated.

Derivative Instruments

The Company may use derivative financial instruments to hedge all or a portion of the interest rate risk associated with its borrowings. Certain of the techniques used to hedge exposure to interest rate fluctuations may also be used to protect against declines in the market value of assets that result from general trends in debt markets. The principal objective of such agreements 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 records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

13

AMERICAN REALTY CAPITAL PROPERTIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2012

The accounting for subsequent changes in the fair value of these derivatives depends on whether each has been designed and qualifies for hedge accounting treatment. If the Company elects not to apply hedge accounting treatment, any changes in the fair value of these derivative instruments is recognized immediately in gains (losses) on derivative instruments in the consolidated statement of operations. If the derivative is designated and qualifies for hedge accounting treatment the change in the estimated fair value of the derivative is recorded in other comprehensive income (loss) to the extent that it is effective. Any ineffective portion of a derivative's change in fair value will be immediately recognized in earnings.

Revenue Recognition

Upon the acquisition of real estate, certain properties will have leases where minimum rent payments increase during the term of the lease. The Company will record rental revenue for the full term of each lease on a straight-line basis. When the Company acquires a property, the term of existing leases is considered to commence as of the acquisition date for the purposes of this calculation. Cost recoveries from tenants are included in tenant reimbursement income in the period the related costs are incurred, as applicable.

The Company's revenues, which are derived primarily from rental income, include rents that each tenant pays in accordance with the terms of each lease reported on a straight-line basis over the initial term of the lease. Since many of the leases provide for rental increases at specified intervals, straight-line basis accounting requires the Company to record a receivable, and include in revenues, unbilled rent receivables that the Company will only receive if the tenant makes all rent payments required through the expiration of the initial term of the lease. The Company defers the revenue related to lease payments received from tenants in advance of their due dates.

The Company continually reviews receivables related to rent and unbilled rent receivables and determines collectability by taking into consideration the tenant's payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area in which the property is located. In the event that the collectability of a receivable is in doubt, the Company will record an increase in the allowance for uncollectible accounts or record a direct write-off of the receivable in the consolidated statements of operations and comprehensive loss. As of December 31, 2012 and 2011, the Company determined that there was no allowance for uncollectible accounts necessary.

Offering and Related Costs

Offering and related costs include costs incurred in connection with the Company's issuance of common stock. These costs include, but are not limited to, (i) legal, accounting, printing, mailing and filing fees; (ii) escrow related fees, and (iii) reimbursement to the Dealer Manager for amounts they paid to reimburse the bonified due diligence expenses of broker-dealers.

Share-Based Compensation

The Company has a stock-based incentive award plan for its affiliated Manager, non-executive directors, officers, other employees and independent contractors who are providing services to the Company, as applicable, and a non-executive director restricted share plan, which are accounted for under the guidance for share-based payments. The expense for such awards is included in general and administrative expenses and is recognized over the vesting period or when the requirements for exercise of the award have been met. See Note 12 — Share-Based Compensation for additional information on these plans.

Income Taxes

Each of the Company and ARCT III qualified as REITs under Sections 856 through 860 of the Internal Revenue Code (the “Code”) commencing with the taxable year ended December 31, 2011. Being qualified for taxation as a REIT, each of the Company and ARCT III generally will not be subject to federal corporate income tax to the extent it distributes its REIT taxable income to its stockholders, and so long as it distributes at least 90% of its REIT taxable income. REITs are subject to a number of other organizational and operational requirements. Each of the Company and ARCT III may still be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed income.

Per Share Data

Income (loss) per basic share of common stock is calculated by dividing net income (loss) less dividends on unvested restricted stock and dividends on preferred shares by the weighted-average number of shares of common stock issued and outstanding during such period. Diluted income (loss) per share of common stock considers the effect of potentially dilutive shares of common stock outstanding during the period.

Reportable Segments

The Company has determined that it has one reportable segment, with activities related to investing in real estate. The Company's investments in real estate generate rental revenue and other income through the leasing of properties, which comprised 100% of its total consolidated revenues. Although the Company's investments in real estate will be geographically diversified throughout the United States, management evaluates operating performance on an individual property level. The Company's properties have been aggregated into one reportable segment.

Recent Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board (the “FASB”) issued guidance that expands the existing disclosure requirements for fair value measurements, primarily for Level 3 measurements, which are measurements based on unobservable inputs such as the Company’s own data. This guidance is largely consistent with current fair value measurement principles with few exceptions that do not result in a change in general practice. The guidance was applied prospectively and was effective for interim and annual reporting periods ending after December 15, 2011. The adoption of this guidance did not have a material impact on the Company’s financial position or results of operations as the guidance relates only to disclosure requirements.

In June 2011, the FASB issued guidance requiring entities to present items of net income and other comprehensive income either in one continuous statement – referred to as the statement of comprehensive income – or in two separate, but consecutive, statements of net income and other comprehensive income. The new guidance does not change which components of comprehensive income are recognized in net income or other comprehensive income, or when an item of other comprehensive income must be reclassified to net income. In December 2011, the FASB deferred certain provisions of this guidance related to the presentation of certain reclassification adjustments out of accumulated other comprehensive income, by component in both the statement and the statement where the reclassification is presented. This guidance was applied prospectively and was effective for interim and annual reporting periods ended after December 15, 2011. The adoption of this guidance did not have a material impact on the Company’s financial position or results of operations but changed the location of the presentation of other comprehensive income to more closely associate the disclosure with net income.

In September 2011, the FASB issued guidance that allows entities to perform a qualitative analysis as the first step in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If it is determined that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then a quantitative analysis for impairment is not required. The guidance was effective for interim and annual impairment tests for fiscal periods beginning after December 15, 2011. The adoption of this guidance did not have a material impact on the Company's financial position or results of operations.

In December 2011, the FASB issued guidance which contains new disclosure requirements regarding the nature of and entity's rights of offset and related arrangements associated with its financial instruments and derivative instruments. The new disclosures are designed to make financial statements prepared under U.S. GAAP more comparable to those prepared under International Financial Reporting Standards and will give the financial statement users information about both gross and net exposures. The guidance is effective for interim and annual reporting periods beginning on or after January 1, 2013. The adoption of this guidance is not expected to have a material impact on the Company's financial position or results of operations.

In July 2012, the FASB issued revised guidance intended to simplify how an entity tests indefinite-lived intangible assets for impairment. The amendments will allow an entity first to assess qualitative factors to determine whether it is necessary to perform a quantitative impairment test. An entity will no longer be required to calculate the fair value of an indefinite-lived intangible asset and perform the quantitative test unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The amendments are effective for annual and interim indefinite-lived intangible asset impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption was permitted. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations, or cash flows.

In February 2013, the FASB issued guidance which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The guidance is effective for annual and interim periods beginning after December 15, 2012 with early adoption permitted. The adoption of this guidance, which is related to disclosure only, did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

December 31, 2012

In February 2013, the FASB issued new accounting guidance clarifying the accounting and disclosure requirements for obligations resulting from joint and several liability arrangements for which the total amount under the arrangement is fixed at the reporting date. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2013. The Company does not expect the adoption of this guidance to have a material impact on the Company's consolidated financial position, results of operations or cash flows.

Note 5 — Credit Facilities

On September 7, 2011, the Company obtained a senior secured revolving credit facility with RBS of up to $150.0 million subject to providing qualified collateral, among other conditions. The proceeds of advances made under the credit agreement may have been used to finance the acquisition of net leased, investment or non-investment grade leased properties and for other permitted corporate purposes. Up to $10.0 million of the facility was available for letters of credit. The credit agreement had a term of 36 months and a maturity date of September 7, 2014, and could have been be extended at the Company's option for an additional 24 months.

Any advance made under the credit facility bore floating interest at per annum rates equal to the one-month London Interbank Offered Rate (“LIBOR”) plus 2.15% to 2.90% depending on the Company's loan to value ratio as specified in the credit agreement. In the event of a default, the lender had the right to terminate its obligations under the credit agreement, including the funding of future advances, and to accelerate the payment on any unpaid principal amounts outstanding. The credit facility required a fee of 0.15% on the unused balance if amounts outstanding under the facility are 50% or more of the total facility amount and 0.25% on the unused balance if amounts outstanding under the facility were less than 50% of the total facility amount.

As of December 31, 2012, there was $124.6 million outstanding on this facility, which bore an interest rate of 3.11%, collateralized by 114 properties. At December 31, 2012, there was $20.4 million available to the Company for future borrowings. At December 31, 2011, there was $42.4 million outstanding on this facility with an interest rate of 3.17%, collateralized by 59 properties. In conjunction with the Merger the credit facility was repaid in full and terminated.

On July 20, 2012, ARCT III, through ARCT III OP, entered into a senior revolving credit facility (the “Senior Facility”) in the amount of $100.0 million with RBS. The Senior Facility had a term of 36 months and a maturity date in July 2015, and could have been extended for an additional 12 months. ARCT III had the option, based upon its corporate leverage, to draw loans under the Senior Facility priced at either: (a) LIBOR, plus an applicable margin that ranges from 2.10% to 3.50%; or (b) the Base Rate, plus an applicable margin that ranges from 2.50% to 3.00%. Base Rate is defined in the Senior Facility agreement as the greater of (i) the fluctuating annual rate of interest announced from time to time by RBS as its “prime rate” or (ii) 1.0% above the federal funds effective rate. The Senior Facility included an unused fee per annum of 0.25% and 0.15%, if the unused balance of the Senior Facility exceeded or was less than 50% of the available facility, respectively.

The Senior Facility provided for monthly interest payments, with all principal outstanding being due on the maturity date. Borrowings under the Senior Facility were permitted to be prepaid from time to time and at any time, in whole or in part, without premium or penalty, subject to reimbursement of certain costs and expenses. In the event of a default, each lender had the right to terminate its obligations under the Senior Facility, and to accelerate the payment on any unpaid principal amount of all outstanding loans. ARCT III had guaranteed the obligations under the Senior Facility. The Senior Facility required ARCT III to meet certain financial covenants, including the maintenance of certain financial ratios (such as specified debt to equity and debt service coverage ratios) as well as the maintenance of a minimum net worth. As of December 31, 2012, ARCT III was in compliance with the debt covenants under the Senior Facility agreement.

As of December 31, 2012, ARCT III had no outstanding borrowings under the Senior Facility. ARCT III incurred $0.1 million in unused fees during the year ended December 31, 2012.

December 31, 2012

On February 14, 2013, simultaneous with ARCT III entering into the New Credit Facility, ARCT III terminated the Senior Facility agreement with RBS.

The Company’s sources of financing generally require financial covenants, as well as restrictions on corporate guarantees, the maintenance of certain financial ratios (such as specified debt to equity and debt service coverage ratios) as well as the maintenance of a minimum net worth. At December 31, 2012 and 2011, the Company was in compliance with the debt covenants under the RBS Facility agreement.

New Credit Facility

On February14, 2013, ARCT III, entered into the New Credit Facility with Wells Fargo Bank, National Association, as administrative agent, RBS and Regions Bank, as syndication agents, and Capital One, N.A. and JP Morgan Chase Bank, N.A., as documentation agents. Since that date the facility has been augmented to increase the commitments of certain lenders and add Bank of America N.A., Barclays Bank PLC, TD Bank N.A., U.S. Bank N.A., Union Bank N.A., UBS AG, Comerica Bank and First Tennessee Bank, as lenders.

These additional commitments increased the facility to $1.45 billion. The New Credit Facility has an accordion feature, which if exercised in full, the aggregate commitments (comprised of revolving, term loan and delayed draw commitments) under the credit agreement would be $2.5 billion, subject to borrowing base availability.

The New Credit Facility contains a $810.0 million term loan facility and a $640.0 million revolving credit facility. Loans under the New Credit Facility are priced at a floating interest rate of LIBOR plus 1.60% to 2.20%, based upon the Company’s current leverage. To the extent that the Company receives an investment grade credit rating as determined by a major credit rating agency, at the Company's election, advances under the New Credit Facility will be priced at their applicable rate plus 0.90% to 1.75% and term loans will be priced at a floating interest rate of LIBOR plus 1.15% to 2.00%, based upon the Company’s then current investment grade credit rating. The Company may also make fixed rate borrowings under the New Credit Facility.

The New Credit Facility provides for monthly interest payments. In the event of a default, each lender has the right to terminate its obligations under the credit facility, and to accelerate the payment on any unpaid principal amount of all outstanding loans. The Company has guaranteed the obligations under the credit facility. The revolving credit facility will terminate on February 14, 2017, unless extended, to which the term loan facility will terminate on February 14, 2018. The Company may prepay borrowings under the New Credit Facility and, to the extent that borrowings are unused under the revolving credit facility and the term loan facility, the Company incurs an unused fee of 0.15% to 0.25% per annum on the unused amount depending on the unused balance as a percentage of the total facility and the type of funding. The New Credit Facility also requires the Company to maintain certain property available for collateral as a condition to funding.

As of December 31, 2012 and 2011, the Company was in compliance with the debt covenants under the mortgage loan agreements.

Note 7 — Investment Securities

At December 31, 2012, the Company had investments in redeemable preferred stock and senior notes, accounted for as debt securities, with a fair value of $41.7 million. These investments were considered available-for-sale securities and therefore increases or decreases in the fair value of these investments are recorded in accumulated other comprehensive income as a component of equity on the consolidated balance sheet unless the securities are considered to be permanently impaired at which time the losses are reclassified to expense.

The following table details the unrealized gains and losses on investment securities as of December 31, 2012. The Company did not have any such investments as of December 31, 2011 (amounts in thousands):

	December 31, 2012
	Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
Investment securities	$	41,747	$	223	$	(316	)	$	41,654

The Company’s preferred stock investments were redeemable at the respective issuer’s option after five years from issuance. The senior notes had a weighted-average maturity of 29.6 years and a weighted-average interest rate of 5.7% as of December 31, 2012. These investments were sold in February 2013.

Note 8 — 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.

20

AMERICAN REALTY CAPITAL PROPERTIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2012

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 rare.

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 December 31, 2012, 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. The Company’s interest rate cap derivative measured at fair value on a recurring basis as of December 31, 2012 was zero and was classified in Level 2 of the fair value hierarchy.

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.

The Company's preferred units, senior note investments and common stock are in active markets and therefore, due to the availability of quoted market prices in active markets, classified these investments as Level 1 in the fair value hierarchy.

The following table presents information about the Company’s assets and liabilities (including derivatives that are presented net) measured at fair value on a recurring basis as of December 31, 2012 and 2011, aggregated by the level in the fair value hierarchy within which those instruments fall (amounts in thousands):

	Quoted Prices in Active Markets Level 1		Significant Other Observable Inputs Level 2			Significant Unobservable Inputs Level 3		Total

December 31, 2011
Interest rate swap	$	—	$	(98	)	$	—	$	(98	)

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 of the fair value hierarchy during the year ended December 31, 2012.

The Company is required to disclose the fair value of financial instruments for which it is practicable to estimate that value. The fair value of short-term financial instruments such as cash and cash equivalents, due to affiliates and accounts payable approximate their carrying value on the accompanying consolidated balance sheets due to their short-term nature.

The fair value of mortgage notes payable are obtained by calculating the present value at current market rates. The terms of the RBS Facility and the Company's level ratio are considered commensurate with the market, as such the outstanding balance on the facility approximates fair value.

Note 9 — 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 caps 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 caps designated as cash flow hedges involve the receipt of variable-rate amounts if interest rates rise above the cap 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. Such derivatives are used to hedge the variable cash flows associated with forecasted 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 $1.5 million will be reclassified from other comprehensive income as an increase to interest expense.

As of December 31, 2012 , 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	Balance Sheet Location	Number of Instruments	Notional Amount
Interest Rate Swaps	Derivatives, at fair value	7	$	152,590

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 December 31, 2012, the fair value of the derivatives in a net liability position, including accrued interest but excluding any adjustment for nonperformance risk related to these agreements was $4.1 million. As of December 31, 2012, 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 $4.1 million at December 31, 2012.

Note 10 — Convertible Preferred Stock

The table above excludes 140.7 million shares of common stock that was issued to the share holders of ARCT III's common stock in conjunction with the Merger.

The consolidated financial statements are presented as if the Merger had occurred prior to December 31, 2012, resulting in total common stock issued and outstanding of 179.2 million shares, including restricted shares of 0.3 million. Such calculation of the Company's common stock issued and outstanding at December 31, 2012 is based on the combination of 11.2 million shares of the Company's common stock issued and outstanding prior to the Merger, and 168.0 million shares of the Company's common stock based upon the Exchange Ratio applied on 176.9 million shares of ARCT III common stock upon consummation of the Merger, pursuant to the Merger Agreement, if all ARCT III shares were converted to Company stock.

Upon the closing of the Merger, 29.2 million shares of the then outstanding shares of ARCT III's common stock were paid in cash at $12.00 per share, which equals 27.7 million shares of the Company's common stock after the application of the Exchange Ratio. In addition, upon closing of the Merger, 148.1 million shares of ARCT III's common stock were converted to shares of Company's common stock at the Exchange Ratio, resulting in an additional 140.7 million shares of the Company's common stock outstanding after the exchange.

The Company's board of directors has authorized, and the Company began paying, dividends since October 2011 on the fifteenth day of each month to stockholders of record on the eight day of such month. Since October 2011, the board of directors of the Company has authorized the following increases in the Company's dividend.

Note 12 — Share-Based Compensation

Equity Plan

The Company has adopted the American Realty Capital Properties, Inc. Equity Plan (the “Equity Plan”), which provides for the grant of stock options, restricted shares of common stock, restricted stock units, dividend equivalent rights and other equity-based awards to the Manager, non-executive directors, officers and other employees and independent contractors, including employees or directors of the Manager and its affiliates who are providing services to the Company.

The Company 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 Manager in connection with the IPO. All such awards of shares will vest ratably on a quarterly or annual basis over a three-year period beginning on the first anniversary of the date of grant and shall provide for “distribution equivalents” with respect to this restricted stock, whether or not vested, at the same time and in the same amounts as dividends are paid to the stockholders.

In February 2013, the Company granted 325,000 restricted shares of common stock to the Manager and certain employees. These shares did not vest upon the consummation of the Merger but will vest ratably over a three-year period and shall provide for “distribution equivalents” with respect to this restricted stock, whether or not vested, at the same time and in the same amounts as dividends are paid to the stockholders.

Director Stock Plan

The Company has adopted the American Realty Capital Properties, Inc. Non-Executive Director Stock Plan (the "Director Stock Plan"), which provides for the grant of restricted shares of common stock to each of the Company's three independent directors, each of whom is a non-executive director. Awards of restricted stock will vest ratably over a five-year period following the first anniversary of the date of grant in increments of 20.0% per annum, subject to the director’s continued service on the board of directors, and shall 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 December 31, 2012, a total of 99,000 shares of common stock are reserved for issuance under the Director Stock Plan.

The fair value of restricted common stock awards under the Equity Plan and Director Stock Plan is determined on the grant date using the closing stock price on NASDAQ that day. The fair value of restricted common stock under the Equity Plan and Director Stock Plan is updated at the end of each quarter based on the quarter end closing stock price through the final vesting date.

Restricted Share Plan

ARCT III had an employee and director incentive restricted share plan (the “RSP”), which provided for the automatic grant of 3,000 restricted shares of common stock to each of its independent directors, without any further action by ARCT III’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 first anniversary of the date of grant in increments of 20.0% per annum. The RSP provided ARCT III with the ability to grant awards of restricted shares to its directors, officers and employees (if ARCT III ever had employees), employees of ARCT III's Advisor and its affiliates, employees of entities that provided services to ARCT III, directors of the ARCT III Advisor or of entities that provided services to ARCT III, certain consultants to ARCT III and the ARCT III Advisor and its affiliates or to entities that provided services to ARCT III.

The following tables detail the restricted shares activity within the Equity Plan, Director Stock Plan and RSP during the years ended December 31, 2012 and 2011:

For the years ended December 31, 2012 and 2011, compensation expense for restricted shares was $1.2 million and $0.2 million, respectively. There was $0.1 million compensation expense for restricted shares for the year ended December 31, 2010.

Stock Option Plan

ARCT III had a stock option plan (the “Stock Option Plan”) which authorized the grant of nonqualified stock options to its independent directors, officers, advisors, consultants and other personnel, subject to the absolute discretion of its board of directors and the applicable limitations of the Stock Option Plan. The exercise price for all stock options granted under the Stock Option Plan were fixed at $10.00 per share until the ARCT III IPO terminated, and thereafter the exercise price for stock options granted to the independent directors were equal to the fair market value of a share on the last business day preceding the annual meeting of stockholders. A total of 0.5 million shares had been authorized and reserved for issuance under the Stock Option Plan. As of December 31, 2012 and 2011, no stock options were issued under the Stock Option Plan. The Stock Option Plan was terminated in February 2013.

Multi-Year Performance Plan

Upon consummation of the Merger, the Company entered into the 2013 Advisor Multi-Year Outperformance Agreement (the “OPP”) with the Manager, whereby the Manager will be able to potentially earn compensation upon the attainment of stockholder value creation targets.

Under the OPP, the manager was granted 8,241,101 long term incentive plan units ("LTIP Units") of the OP, which will be earned or forfeited based on the Company's total return to stockholders (including both share price appreciation and common stock distributions) ("Total Return"), for the three year period consisting of:

• Absolute Component: 4.0% of any excess Total Return attained above an absolute hurdle of 7.0% for each annual measurement period, non-compounded, 14.0% for the interim measurement period and 21.0% for the full performance period; and

• Relative Component: 4.0% of any excess Total Return attained above the Total Return for the performance period of a peer group comprised of the following companies: CapLease, Inc.; EPR Properties; Getty Realty Corporation; Lexington Realty Trust; National Retail Properties, Inc.; and Realty Income Corporation.

The award will be funded ("OPP Pool") up to a maximum award opportunity equal to 5% of the Company's equity market capitalization at the Merger date of $2.1 billion (the "OPP Cap"). Awards under the OPP are dependent on achieving an annual hurdle, that commenced December 11, 2012, an interim (two-year) hurdle and then the aforementioned three-year hurdle ending on December 31, 2015.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2012

In order to further ensure that the interests of the Manager are aligned with the Company's investors, the Relative Component is subject to a ratable sliding scale factor as follows:

• 100.0% will be earned if the Company attains a median Total Return of at least 6.0% for each annual measurement period, non-compounded, at least 12.0% for the interim measurement period, and at least 18.0% for the full performance period;

• 50.0% will be earned if the Company attains a median Total Return of at least 0.0% for each measurement period;

• 0.0% will be earned if the Company attains a median Total Return of less than 0.0% for each measurement period; and

• A percentage from 50.0% to 100.0% calculated by linear interpolation will be earned if the Company's median Total Return is between 0.0% and th percentage set for each measurement period.

For each year during the performance period a portion of the OPP Cap equal to a maximum of up to 1.25% of the Company's equity market capitalization of $2.1 billion will be “locked-in” based upon the attainment of the performance hurdles set forth above for each annual measurement period. In addition, a portion of the OPP Cap equal to a maximum of up to 3.0% of the Company's equity market capitalization will be “locked-in” based upon the attainment of the performance hurdles set forth above for the interim measurement period, which if achieved, will supersede and negate any prior “locked-in” portion based upon annual performance through December 31, 2013 and 2014 (i.e., a maximum award opportunity equal to a maximum of up to 3.0% of the Company's equity market capitalization may be “locked-in” through December 31. 2014).

Following the performance period, the Absolute Component and the Relative Component will be calculated separately and then added together to determine the aggregate award earned under the OPP, which will be the lesser of the sum of the two components and the OPP Cap. The OPP Pool will be used to determine the number of LTIP units that vest. Any unvested LTIP units will be immediately forfeited on December 31, 2015. At March 31, 2013, 100% of the pool has been allocated.

The Manager will be entitled to convert 33.3% of the LTIP units earned into OP Units on each of December 31, 2015, 2016 and 2017 and within 30 days following such date. In addition, the OPP provides for accelerated earning and vesting of LTIP Units and redemption of vested LTIP Units for cash if the Manager is terminated or if the Company experiences a change in control. The Manager will be entitled to receive a tax gross-up in the event that any amounts paid to it under the OPP constitute “parachute payments” as defined in Section 280G of the Internal Revenue Code of 1986, as amended (the "Code").

The fair value of the LTIP Units granted are being amortized over the performance period. The Company did not incur expenses for the OPP during the years ended December 31, 2012 and 2011, respectively.

Other Share-Based Compensation

ARCT III was permitted to issue common stock in lieu of cash to pay fees earned by its directors, at the respective director's election. There were no restrictions on the shares issued since these payments in lieu of cash relate to fees earned for services performed.

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:

Since the announcement of the Merger Agreement on December 17, 2012, Randell Quaal filed a putative class action lawsuit filed on January 19, 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 lawsuit alleges, among other things, that the board of ARCT III breached its fiduciary duties in connection with the transactions contemplated under the 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 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.

The Company maintains directors and officers liability insurance which the Company believes should provide coverage to the Company and its officers and directors for most or all of any costs, settlements or judgments resulting from the lawsuit.

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.

Each of the Company and ARCT III paid the Manager and the ARCT III Advisor, as applicable, an acquisition fee equal to 1.0% of the contract purchase price (including assumed indebtedness) of each property the Company or ARCT III, as applicable, acquired. The acquisition fee was payable in cash at the closing of each acquisition. In conjunction with the Merger, it was agreed that these fees would no longer be paid to either party. Acquisition fees are recorded in acquisition related costs in the consolidated statement of operations.

Each of the Company and ARCT III paid the Manager and the ARCT III Advisor, as applicable, a financing fee equal to 0.75% of the amount available under any secured mortgage financing or refinancing that the Company or ARCT III, as applicable, obtained and used for the acquisition of properties that was arranged by the Manager or ARCT III Advisor, as applicable. The financing coordination fee was payable in cash at the closing of each financing. In conjunction with the Merger, it was agreed that these fees would no longer be paid to either party. Financing fees are recorded in deferred costs on the consolidated balance sheet and amortized to interest expense over the term of the related debt.

The Company paid the Manager an annual base management fee equal to 0.50% per annum of the average unadjusted book value of the Company's real estate assets, calculated and payable monthly in advance, provided that the full amount of the distributions declared by the Company for the six immediately preceding months was equal to or greater than certain net income thresholds related to our operations. Our Manager waived such portion of its management fee in excess of such thresholds. The management fee is payable in cash. In conjunction with the Merger, the base management fee was reduced to 0.40% per annum for the unadjusted book value of assets over $3.0 billion. Management fees, if accrued are recorded in Operating fees to affiliates in the consolidated statements of operations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2012

Until July 1, 2012, ARCT III paid the ARCT III Advisor an asset management fee of 0.75% per annum of the cost of its assets (cost includes the purchase price, acquisition expenses, capital expenditures and other customarily capitalized costs, but excludes acquisition fees) plus costs and expenses incurred by the ARCT III Advisor in providing asset management services; provided, however, that the asset management fee was reduced by any amounts payable to ARCT III's property manager as an oversight fee, such that the aggregate of the asset management fee and the oversight fee did not exceed 0.75% per annum of the cost of ARCT III's assets plus costs and expenses incurred by the ARCT III Advisor in providing asset management services. Prior to July 1, 2012, this fee was payable in monthly installments at the discretion of ARCT III's board of directors in cash, common stock or restricted stock grants, or any combination thereof. Asset management fees, if accrued are recorded in Operating fees to affiliates in the consolidated statements of operations.

Effective July 1, 2012, the payment of asset management fees in monthly installments in cash, shares or restricted stock grants, or any combination thereof to the ARCT III Advisor was eliminated. Instead, ARCT III issued (subject to periodic approval by its board of directors) to the ARCT III Advisor performance-based restricted partnership units of the ARCT III OP designated as “Class B units,” which were intended to be profits interests and to vest, and no longer be subject to forfeiture, at such time as: (x) the value of the ARCT III OP’s assets plus all distributions made equal 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”); and among other potential events, a liquidity event accrued.

The ARCT III Advisor received distributions on unvested Class B units equal to the distribution rate received on ARCT III common stock. Such distributions on issued Class B units were included as general and administrative expense in the consolidated statement of operations until the performance condition is considered probable to occur. 145,022 Class B units were approved by ARCT III's board of directors as of December 31, 2012. During January and February 2013, ARCT III's board of directors approved, and ARCT III issued, 603,599 Class B units to the ARCT III Advisor for its asset management services provided. As of December 31, 2012, ARCT III did not consider achievement of the performance condition to be probable as the shareholder vote for the Merger, which would allow vesting of these Class B Units, was not completed. The performance condition related to these Class B units was satisfied upon the completion of the Merger and expense of $9.9 million was recorded at that time. The Class B units then converted to ARCT III OP units which converted to 711,190 OP Units after the application of the Exchange Ratio. These expenses were recorded in Merger and other transaction related in the consolidated statement of operations.

The Company may be required to pay the Manager a quarterly incentive fee, calculated based on 20 percent of the excess Company annualized core earnings (as defined in the management agreement with the Manager) over the weighted average number of shares multiplied by the weighted average price per share of common stock. One half of each quarterly installment of the incentive fee will be payable in shares of common stock. The remainder of the incentive fee will be payable in cash. No such incentive fees have been paid to the Manager since inception.

ARCT III paid an affiliate of the Sponsor, unless it contracted with a third party, a property management fee of up to 2% of gross revenues from ARCT III's stand-alone single-tenant net leased properties and 4% of gross revenues from its multi-tenant properties, plus, in each case, market-based leasing commissions applicable to the geographic location of the property.  ARCT III also reimbursed the affiliate for property level expenses.  If ARCT III contracted directly with third parties for such services, it paid them customary market fees and paid the affiliated property manager, an oversight fee of up to 1.0% of the gross revenues of the property managed. Property management fees are recorded in Operating fees to affiliates in the consolidated statement of operations.

In order to facilitate the smooth transition of property management services following the consummation of the Merger, the Company, the OP and the Sponsor agreed that the Property Management and Leasing Agreement will be extended for a 60 day period following the consummation of the Merger for which the Company paid the Sponsor $2.3 million. These fees were recorded in Merger and transaction related in the consolidated statement of operations.

The Company is required to reimburse the Manager for all out-of-pocket costs actually incurred by the Manager, including without limitation, legal fees and expenses, due diligence fees and expenses, other third party fees and expenses, costs of appraisals, travel expenses, nonrefundable option payments and deposits on properties not acquired, accounting fees and expenses, title insurance premiums and other closing costs, personnel costs and miscellaneous expenses relating to the selection, acquisition and due diligence of properties. The Company's reimbursement obligation is not subject to any dollar limitation. Expenses will be reimbursed in cash on a monthly basis following the end of each month. However, the Company will not reimburse the Manager for the salaries and other compensation of its personnel. Reimbursements are recorded based on the related activity to which the expense relates.

The Company entered into an Asset Purchase and Sale Agreement with the Sponsor pursuant to which, concurrently with the closing of the Merger and in connection with the internalization by the Company of certain property level management and accounting activities, the Sponsor sold to the OP certain furniture, fixtures, equipment and other assets used by the Sponsor in connection with managing the property level business and operations and accounting functions of the Company and the OP, and included at the cost of such assets, for an aggregate price of $5.8 million, which includes the reimbursement of certain costs and expenses incurred by the Sponsor in connection with the Merger.

On February 28, 2013, the OP entered into a Contribution and Exchange Agreement (the "Contribution and Exchange Agreement") with the ARCT III OP and American Realty Capital III Special Limited Partnership, LLC, the holder of the special limited partner interest in the ARCT III OP (the "Special Limited Partner"). The Special Limited Partner was entitled to receive certain distributions from the ARCT III 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 III OP). The Merger constituted an "investment liquidity event," as a result of which the Special Limited Partner, in connection with management's successful attainment of the 6.0% performance hurdle and the return to ARCT III's stockholders of approximately $557.3 million in addition to their initial investment, was entitled to receive a subordinated distribution of net sales proceeds from the ARCT III OP equal to approximately $98.4 million. Pursuant to the Contribution and Exchange Agreement, the Special Limited Partner contributed its interest in the ARCT III OP, inclusive of the subordinated distribution proceeds received, to the ARCT III OP in exchange for 7.6 million ARCT III OP Units. Upon consummation of the Merger, these ARCT III OP Units were immediately converted to 7.3 million OP Units after application of the Exchange Ratio. In conjunction with the Merger Agreement, the Special Limited Partner agreed to a minimum one year holding period for these OP units before converting them to shares of Company common stock.

Investment by Affiliate

In connection with the Merger agreement, the Special Limited Partner invested $0.8 million in exchange for 56,797 ARCP OP Units after the effect of the exchange ratio.

Note 15 — Economic Dependency

Under various agreements, the Company has engaged or will engage the Manager and its affiliates to provide certain services that are essential to the Company, including asset management services, supervision of the management and leasing of properties owned by the Company, asset acquisition and disposition decisions, the sale of shares of the Company’s common stock, as well as other administrative responsibilities for the Company including accounting services and investor relations. 

As a result of these relationships, the Company is dependent upon the Manager, the Sponsor and their affiliates. In the event that these companies were unable to provide the Company with the respective services, the Company would be required to find alternative providers of these services. As a result of the Merger with ARCT III, the Company internalized certain accounting and property acquisition services previously performed by the Manager and its affiliates. The Company may from time to time engage the Manager for legal, information technology or other support services for which it will pay market rates.

Note 17 — Discontinued Operations and Properties Held for Sale

The Company separately classifies properties held for sale in the accompanying consolidated balance sheets and operating results for those properties as discontinued operations in the accompanying consolidated statements of operations and comprehensive loss. In the normal course of business, changes in the market may compel the Company to decide to classify a property as held for sale or reclassify a property that is designated as held for sale back to held for investment. In these situations, the property is transferred to held for sale or back to held for investment at the lesser of fair value or depreciated cost. As of December 31, 2012 and 2011, the Company held one and two vacant properties, respectively, which were classified as held for sale on the accompanying respective consolidated balance sheets.

On July 1, 2012, the Company sold one of the vacant properties, which was located in Havertown, PA, for net proceeds of $0.6 million and recorded a loss on held for sale properties of $0.5 million.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Accounting

The accompanying consolidated financial statements are prepared on the accrual basis of accounting in accordance with U.S. GAAP.

Principles of Consolidation and Basis of Presentation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. In determining whether the Company has a controlling financial interest in a joint venture and the requirement to consolidate the accounts of that entity, management considers factors such as ownership interest, authority to make decisions and contractual and substantive participating rights of the other partners or members as well as whether the entity is a variable interest entity for which the Company is the primary beneficiary.

Reclassification

Certain reclassifications have been made to the previously issued historical consolidated financial statements of the Company and ARCT III to conform to this consolidated presentation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Management makes significant estimates regarding revenue recognition, to record investments in real estate, real estate taxes, and derivative financial instruments and hedging activities, as applicable.

Formation Transactions

Upon the effectiveness of the IPO, the Company acquired certain properties from affiliated entities of the Company and, as such, the Company was no longer considered to be in the development stage. The contribution of the properties from affiliates in the initial formation of the Company was accounted for as a reorganization of entities under common control and therefore all assets and liabilities related to the contributed properties were accounted for on the carryover basis of accounting whereby the real estate investments were contributed at amortized cost and all assets and liabilities of the predecessor entities became assets and liabilities of the Company.

Real Estate Investments

The Company records acquired real estate at cost and makes assessments as to the useful lives of depreciable assets. The Company considers the period of future benefit of the asset to determine the appropriate useful lives. Depreciation is computed using a straight-line method over the estimated useful life of 40 years for buildings, five to 15 years for building fixtures and improvements and the remaining lease term for acquired intangible lease assets.

Impairment of Long Lived Assets

Operations related to properties that have been sold or properties that are intended to be sold are presented as discontinued operations in the statement of operations for all periods presented, and properties intended to be sold are designated as “held for sale” on the accompanying consolidated balance sheets.

When circumstances indicate the carrying value of a property may not be recoverable, the Company reviews the asset for impairment. This review is based on an estimate of the future undiscounted cash flows, excluding interest charges, expected to result from the property’s use and eventual disposition. These estimates consider factors such as expected future operating income, market and other applicable trends and residual value, as well as the effects of leasing demand, competition and other factors. If impairment exists, due to the inability to recover the carrying value of a property, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair value of the property for properties to be held and used.

For properties held for sale, the impairment loss is the adjustment to fair value less estimated cost to dispose of the asset. These assessments have a direct impact on net income because recording an impairment loss results in an immediate negative adjustment to net income. At December 31, 2012, and 2011, the Company had one and two, respectively, vacant properties classified as properties held for sale. See Note 17 — Discontinued Operations and Properties Held for Sale.

Allocation of Purchase Price of Acquired Assets

The Company allocates the purchase price of acquired properties to tangible and identifiable intangible assets acquired based on their respective fair values. Tangible assets include land, buildings, equipment and tenant improvements on an as-if vacant basis. The Company utilizes various estimates, processes and information to determine the as-if vacant property value. Estimates of value are made using customary methods, including data from appraisals, comparable sales, discounted cash flow analysis and other methods. Identifiable intangible assets include amounts allocated to acquire leases for above- and below-market lease rates, the value of in-place leases, and the value of customer relationships.

Amounts allocated to land, buildings, equipment and fixtures are based on cost segregation studies performed by independent third-parties or on the Company's analysis of comparable properties in its portfolio. Depreciation is computed using the straight-line method over the estimated lives of forty years for buildings, five to ten years for building equipment and fixtures, and the shorter of the useful life or the remaining lease term for tenant improvements.

The aggregate value of intangible assets related to in-place leases is primarily the difference between the property valued with existing in-place leases adjusted to market rental rates and the property valued as if vacant. Factors considered by the Company in its analysis of the in-place lease intangibles include an estimate of carrying costs during the expected lease-up period for each property, taking into account current market conditions and costs to execute similar leases. In estimating carrying costs, the Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up period, which typically ranges from six to 18 months. The Company also estimates costs to execute similar leases including leasing commissions, legal and other related expenses.

Above-market and below-market in-place lease values for owned properties are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between the contractual amounts to be paid pursuant to the in-place leases and management's estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. The capitalized above-market lease intangibles are amortized as a decrease to rental income over the remaining term of the lease. The capitalized below-market lease values will be amortized as an increase to rental income over the remaining term and any fixed rate renewal periods provided within the respective leases. In determining the amortization period for below-market lease intangibles, the Company initially will consider, and periodically evaluate on a quarterly basis, the likelihood that a lessee will execute the renewal option. The likelihood that a lessee will execute the renewal option is determined by taking into consideration the tenant's payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area in which the property is located.

The aggregate value of intangibles assets related to customer relationships is measured based on the Company's evaluation of the specific characteristics of each tenant's lease and the Company's overall relationship with the tenant. Characteristics considered by the Company in determining these values include the nature and extent of the Company's existing business relationships with the tenant, growth prospects for developing new business with the tenant, the tenant's credit quality and expectations of lease renewals, among other factors.

The value of in-place leases is amortized to expense over the initial term of the respective leases, which range primarily from 2 to 20 years. The value of customer relationship intangibles is amortized to expense over the initial term and any renewal periods in the respective leases, but in no event does the amortization period for intangible assets exceed the remaining depreciable life of the building. If a tenant terminates its lease, the unamortized portion of the in-place lease value and customer relationship intangibles is charged to expense.

In making estimates of fair values for purposes of allocating purchase price, the Company utilizes a number of sources, including independent appraisals that may be obtained in connection with the acquisition or financing of the respective property and other market data. The Company also considers information obtained about each property as a result of its pre-acquisition due diligence, as well as subsequent marketing and leasing activities, in estimating the fair value of the tangible and intangible assets acquired and intangible liabilities assumed.

Intangible lease assets of the Company consist of the following as of December 31, 2012 and 2011 (amounts in thousands):

	December 31,
	2012			2011
In-place leases, gross	$	210,959		$	21,777
Accumulated amortization on in-place leases	(11,183		)	(3,282		)
In-place leases, net of accumulated amortization	199,776			18,495
Above market leases, gross	1,264			—
Accumulated amortization on above market leases	(116		)	—
Above market leases, net of accumulated amortization	1,148			—
Total intangible lease assets, net	$	200,924		$	18,495

The following table provides the weighted-average amortization period as of December 31, 2012 for intangible lease assets and the projected amortization expense and adjustments of rental income for the next five years of the Company (amounts in thousands):

	Weighted-Average Amortization Period in Years	2013		2014		2015		2016		2017
In-place leases:
Total to be included in amortization expense	11.9	$	19,265	$	19,234	$	18,855	$	18,586	$	18,049
Above market leases:
Total to be included in rental income	5.0	$	252	$	252	$	252	$	252	$	122
Total intangible lease assets	11.9

Cash and Cash Equivalents

Cash and cash equivalents include cash in bank accounts as well as investments in highly-liquid money market funds with original maturities of three months or less.

The Company deposits cash with high quality financial institutions. These deposits are guaranteed by the Federal Deposit Insurance Company (“FDIC”) up to an insurance limit. At December 31, 2012 and 2011, the Company had deposits of $156.9 million and $19.3 million, respectively, of which $154.8 million and $18.5 million were in excess of the amount insured by the FDIC. Although the Company bears risk to amounts in excess of those insured by the FDIC, it does not anticipate any losses as a result.

Restricted Cash

Restricted cash primarily consists of reserves related to lease expirations as well as maintenance, structural, and debt service reserves.

Deferred Costs, Net

Deferred costs, net consists of deferred financing costs net of accumulated amortization, deferred leasing costs net of accumulated amortization and deferred offering costs.

Deferred financing costs represent commitment fees, legal fees, and other costs associated with obtaining commitments for financing. These costs are amortized over the terms of the respective financing agreements using the effective interest method. Unamortized deferred financing costs are expensed when the associated debt is refinanced or repaid before maturity. Costs incurred in seeking financial transactions that do not close are expensed in the period in which it is determined the financing will not close. At December 31, 2012 and 2011, the Company had $15.1 million and $3.1 million, respectively, of deferred financing costs net of accumulated amortization.

Deferred leasing costs, consisting primarily of lease commissions and payments made to assume existing leases, are deferred and amortized over the term of the lease. At December 31, 2012 and 2011, the Company had $0.2 million and $0.3 million, respectively, of deferred leasing costs, net of accumulated amortization.

Deferred offering costs represent professional fees, fees paid to various regulatory agencies, and other costs incurred in connection with registering to sell shares of the Company's common stock. As of December 31, 2012, the Company had $0.1 million of deferred offering costs related to the Company's $500.0 million universal shelf and resale registration statements filed with the SEC in August 2012. As of December 31, 2011, the Company had no deferred offering costs.

Share Repurchase Program

ARCT III's board of directors had adopted a Share Repurchase Program (“SRP”) that enabled stockholders to sell their shares to ARCT III in limited circumstances. The SRP permitted investors to sell their shares back to ARCT III after they had held them for at least one year, subject to the significant conditions and limitations described below.

The purchase price per share depended on the length of time investors had held such shares as follows: after one year from the purchase date — the lower of $9.25 or 92.5% of the amount they actually paid for each share; after two years from the purchase date —the lower of $9.50 or 95.0% of the amount they actually paid for each share; after three years from the purchase date — the lower of $9.75 or 97.5% of the amount they actually paid for each share; and after four years from the purchase date — the lower of $10.00 or 100% of the amount they actually paid for each share.

ARCT III was only authorized to repurchase shares pursuant to the SRP up to the value of shares issued under the DRIP and limited the amount spent to repurchase shares in a given quarter to the value of the shares issued under the DRIP in that same quarter.

When a stockholder requested repurchases and the repurchases were approved by ARCT III’s board of directors, it reclassified such obligation from equity to a liability based on the settlement value of the obligation. The following table reflects the number of shares repurchased for the years ended December 31, 2012 and 2011. There were no repurchases requested or fulfilled during the period from October 15, 2010 (“ARCT III's date of inception”) to December 31, 2010.

Year ended December 31,	Number of Requests	Number of Shares	Average Price per Share
2011	1	2,375	$	10.00
2012	73	179,104	9.93
Cumulative repurchase requests as of December 31, 2012 (1)	74	181,479	$	9.93

_____________________________

(1) Includes unfulfilled repurchase requests for 35,180 shares at a average price per share of $9.86, which were approved for repurchase as of December 31, 2012.

Upon the Merger the SRP was terminated.

Distribution Reinvestment Plan

Pursuant to the ARCT III distribution reinvestment plan or ("DRIP"), stockholders could have elected to reinvest distributions by purchasing shares of ARCT III common stock in lieu of receiving cash.  No dealer manager fees or selling commissions were paid with respect to shares purchased pursuant to the DRIP.  Participants purchasing shares pursuant to the DRIP had the same rights and were treated in the same manner as if such shares were issued pursuant to ARCT III's initial public offering (the "ARCT III IPO"). Shares issued under the DRIP were recorded within stockholders’ equity in the accompanying consolidated balance sheets in the period distributions were declared. During the years ended December 31, 2012 and 2011, ARCT III issued 2.7 million and 27,169 shares of common stock, respectively, with a value of $26.8 million and $0.3 million, respectively, in each case with a par value per share of $0.01, pursuant to the DRIP. Upon the Merger, the DRIP was terminated.

Derivative Instruments

The Company may use derivative financial instruments to hedge all or a portion of the interest rate risk associated with its borrowings. Certain of the techniques used to hedge exposure to interest rate fluctuations may also be used to protect against declines in the market value of assets that result from general trends in debt markets. The principal objective of such agreements 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 records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

The accounting for subsequent changes in the fair value of these derivatives depends on whether each has been designed and qualifies for hedge accounting treatment. If the Company elects not to apply hedge accounting treatment, any changes in the fair value of these derivative instruments is recognized immediately in gains (losses) on derivative instruments in the consolidated statement of operations. If the derivative is designated and qualifies for hedge accounting treatment the change in the estimated fair value of the derivative is recorded in other comprehensive income (loss) to the extent that it is effective. Any ineffective portion of a derivative's change in fair value will be immediately recognized in earnings.

Revenue Recognition

Upon the acquisition of real estate, certain properties will have leases where minimum rent payments increase during the term of the lease. The Company will record rental revenue for the full term of each lease on a straight-line basis. When the Company acquires a property, the term of existing leases is considered to commence as of the acquisition date for the purposes of this calculation. Cost recoveries from tenants are included in tenant reimbursement income in the period the related costs are incurred, as applicable.

The Company's revenues, which are derived primarily from rental income, include rents that each tenant pays in accordance with the terms of each lease reported on a straight-line basis over the initial term of the lease. Since many of the leases provide for rental increases at specified intervals, straight-line basis accounting requires the Company to record a receivable, and include in revenues, unbilled rent receivables that the Company will only receive if the tenant makes all rent payments required through the expiration of the initial term of the lease. The Company defers the revenue related to lease payments received from tenants in advance of their due dates.

The Company continually reviews receivables related to rent and unbilled rent receivables and determines collectability by taking into consideration the tenant's payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area in which the property is located. In the event that the collectability of a receivable is in doubt, the Company will record an increase in the allowance for uncollectible accounts or record a direct write-off of the receivable in the consolidated statements of operations and comprehensive loss. As of December 31, 2012 and 2011, the Company determined that there was no allowance for uncollectible accounts necessary.

Offering and Related Costs

Offering and related costs include costs incurred in connection with the Company's issuance of common stock. These costs include, but are not limited to, (i) legal, accounting, printing, mailing and filing fees; (ii) escrow related fees, and (iii) reimbursement to the Dealer Manager for amounts they paid to reimburse the bonified due diligence expenses of broker-dealers.

Share-Based Compensation

The Company has a stock-based incentive award plan for its affiliated Manager, non-executive directors, officers, other employees and independent contractors who are providing services to the Company, as applicable, and a non-executive director restricted share plan, which are accounted for under the guidance for share-based payments. The expense for such awards is included in general and administrative expenses and is recognized over the vesting period or when the requirements for exercise of the award have been met. See Note 12 — Share-Based Compensation for additional information on these plans.

Income Taxes

Each of the Company and ARCT III qualified as REITs under Sections 856 through 860 of the Internal Revenue Code (the “Code”) commencing with the taxable year ended December 31, 2011. Being qualified for taxation as a REIT, each of the Company and ARCT III generally will not be subject to federal corporate income tax to the extent it distributes its REIT taxable income to its stockholders, and so long as it distributes at least 90% of its REIT taxable income. REITs are subject to a number of other organizational and operational requirements. Each of the Company and ARCT III may still be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed income.

Per Share Data

Income (loss) per basic share of common stock is calculated by dividing net income (loss) less dividends on unvested restricted stock and dividends on preferred shares by the weighted-average number of shares of common stock issued and outstanding during such period. Diluted income (loss) per share of common stock considers the effect of potentially dilutive shares of common stock outstanding during the period.

Reportable Segments

The Company has determined that it has one reportable segment, with activities related to investing in real estate. The Company's investments in real estate generate rental revenue and other income through the leasing of properties, which comprised 100% of its total consolidated revenues. Although the Company's investments in real estate will be geographically diversified throughout the United States, management evaluates operating performance on an individual property level. The Company's properties have been aggregated into one reportable segment.

Recent Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board (the “FASB”) issued guidance that expands the existing disclosure requirements for fair value measurements, primarily for Level 3 measurements, which are measurements based on unobservable inputs such as the Company’s own data. This guidance is largely consistent with current fair value measurement principles with few exceptions that do not result in a change in general practice. The guidance was applied prospectively and was effective for interim and annual reporting periods ending after December 15, 2011. The adoption of this guidance did not have a material impact on the Company’s financial position or results of operations as the guidance relates only to disclosure requirements.

In June 2011, the FASB issued guidance requiring entities to present items of net income and other comprehensive income either in one continuous statement – referred to as the statement of comprehensive income – or in two separate, but consecutive, statements of net income and other comprehensive income. The new guidance does not change which components of comprehensive income are recognized in net income or other comprehensive income, or when an item of other comprehensive income must be reclassified to net income. In December 2011, the FASB deferred certain provisions of this guidance related to the presentation of certain reclassification adjustments out of accumulated other comprehensive income, by component in both the statement and the statement where the reclassification is presented. This guidance was applied prospectively and was effective for interim and annual reporting periods ended after December 15, 2011. The adoption of this guidance did not have a material impact on the Company’s financial position or results of operations but changed the location of the presentation of other comprehensive income to more closely associate the disclosure with net income.

In September 2011, the FASB issued guidance that allows entities to perform a qualitative analysis as the first step in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If it is determined that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then a quantitative analysis for impairment is not required. The guidance was effective for interim and annual impairment tests for fiscal periods beginning after December 15, 2011. The adoption of this guidance did not have a material impact on the Company's financial position or results of operations.

In December 2011, the FASB issued guidance which contains new disclosure requirements regarding the nature of and entity's rights of offset and related arrangements associated with its financial instruments and derivative instruments. The new disclosures are designed to make financial statements prepared under U.S. GAAP more comparable to those prepared under International Financial Reporting Standards and will give the financial statement users information about both gross and net exposures. The guidance is effective for interim and annual reporting periods beginning on or after January 1, 2013. The adoption of this guidance is not expected to have a material impact on the Company's financial position or results of operations.

In July 2012, the FASB issued revised guidance intended to simplify how an entity tests indefinite-lived intangible assets for impairment. The amendments will allow an entity first to assess qualitative factors to determine whether it is necessary to perform a quantitative impairment test. An entity will no longer be required to calculate the fair value of an indefinite-lived intangible asset and perform the quantitative test unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The amendments are effective for annual and interim indefinite-lived intangible asset impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption was permitted. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations, or cash flows.

In February 2013, the FASB issued guidance which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The guidance is effective for annual and interim periods beginning after December 15, 2012 with early adoption permitted. The adoption of this guidance, which is related to disclosure only, did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

In February 2013, the FASB issued new accounting guidance clarifying the accounting and disclosure requirements for obligations resulting from joint and several liability arrangements for which the total amount under the arrangement is fixed at the reporting date. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2013. The Company does not expect the adoption of this guidance to have a material impact on the Company's consolidated financial position, results of operations or cash flows.

Merger Agreement

Merger Agreement [Abstract]

Mergers, Acquisitions and Dispositions Disclosures [Text Block]

— Merger Agreement

On December 14, 2012, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with ARCT III and certain subsidiaries of each company. The Merger Agreement provided for the merger of ARCT III with and into a subsidiary of the Company (the “Merger”). The Merger was consummated on February 28, 2013.

Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, each outstanding share of common stock of ARCT III was converted into the right to receive (i) 0.95 of a share of the Company's common stock, (the "Exchange Ratio") or (ii) $12.00 in cash. In addition, each outstanding unit of equity ownership of 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 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 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 Exchange Ratio, resulting in an additional 140.7 million shares of the Company's common stock outstanding after the exchange.

Upon the consummation of the Merger, American Realty Capital III Special Limited Partnership, LLC, the holder of the special limited partner interest in the American Realty Capital Operating Partnership III (the "ARCT III OP"), was entitled to subordinated distributions of net sales proceeds from ARCT III OP which resulted in the issuance of units of limited partner interests in the ARCT III OP, when after applying the Exchange Ratio, resulting in the issuance of an additional 7.3 million OP Units. The parties have agreed that such OP Units will be subject to a minimum one-year holding period before being exchangeable into the Company's common stock.

Upon consummation of the Merger, the vesting of the shares of the Company's and ARCT III's outstanding restricted stock was accelerated.

In connection with the Merger, the Company also had entered into an agreement with the Sponsor and its affiliates to internalize certain functions performed by them prior to the Merger, at no cost to the Company, including acquisition, accounting and portfolio management services (the “Internalization”). In connection with the Internalization, (i) the Company and its Sponsor terminated the acquisition and capital services agreement dated September 6, 2011, between the parties, which eliminated acquisition and financing fees payable by the Company and (ii) the Manager reduced asset management fees from an annualized 0.50% of the unadjusted book value of all of the Company's assets to 0.50% for up to $3.0 billion of unadjusted book value of assets and 0.40% of unadjusted book value of assets greater than $3.0 billion. In addition, the Company paid $4.1 million for certain furniture, fixtures, equipment, and $1.7 million for other assets and certain costs associated with the Merger. The Company and the Manager are considered entities under common control, as such, the assets acquired from the Manager were recorded by the Company at their carryover basis.

Accounting Treatment of the Merger

The Company and ARCT III, to the Merger date, were considered to be entities under common control. Both entities' advisors were wholly owned subsidiaries of the Sponsor. The Sponsor and its related parties have significant ownership interests in the Company and had significant ownership of ARCT III through the ownership of shares of common stock and other equity interests. In addition, the advisors of both entities were contractually eligible to charge potential fees for their services to both of the companies including asset management fees, incentive fees and other fees and continue to charge fees to the Company. Due to the significance of these fees, the advisors and ultimately the Sponsor is 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 qualifies them as affiliated companies under common control in accordance with generally accepted accounting principals 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 Merger date. In addition, U.S. GAAP requires that we present historical financial information as if the entities were combined for each period presented, therefore all financial statements including the notes thereto are presented combining ARCP and ARCT III historical financial information.

New Credit Facility

On February 14, 2013, ARCT III, through ARCT III OP, its operating partnership, entered into an unsecured credit facility (the "New Credit Facility"), with Wells Fargo Bank, National Association, as administrative agent, RBS Citizens, N.A. and Regions Bank, as syndication agents, and Capital One, N.A. and JP Morgan Chase Bank, N.A., as documentation agents.

Additionally, upon consummation of the Merger, the Company's senior secured revolving credit facility with RBS (the "RBS Facility") of up to $150.0 million was paid off in full and terminated. ARCT III terminated the Senior Facility (as defined in Note 5 - Credit Facilities) agreement with RBS simultaneous with entering into the New Credit Facility.

See Note 5 — Credit Facilities for further description of the New Credit Facility and repayments and terminations of facilities upon the consummation of the Merger.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization

American Realty Capital Properties, Inc. (the “Company”), is a Maryland corporation incorporated on December 2, 2010 that qualified as a real estate investment trust for U.S. federal income tax purposes beginning in the year ended December 31, 2011. On September 6, 2011, the Company completed its initial public offering (the “IPO”) and its shares of common stock began trading on the NASDAQ Capital Market ("NASDAQ") under the symbol “ARCP” on September 7, 2011.

The Company acquires, owns and operates single-tenant, freestanding commercial real estate properties. The Company has acquired a combination of long-term and medium-term leases and intends to continue to acquire properties with approximately 70% long-term leases and 30% medium-term leases, with an average remaining lease term of 10 to 12 years. The Company considers properties that are leased on a “medium-term” basis to mean properties originally leased long-term (ten years or longer) that currently have a primary remaining lease duration of generally three to eight years, on average. The Company expects this investment strategy to develop growth potential from below market leases. Additionally, the Company owns a portfolio that uniquely combines a portfolio of properties with stable income from high credit quality tenants, with properties that have substantial growth opportunities.

On February 28, 2013, the Company merged with American Realty Capital Trust III, Inc., a Maryland Corporation ("ARCT III"), (see Note 2 — Merger Agreement ).

Prior to the Merger (as defined below) and continuing following the consummation of the Merger, substantially all of the Company's business was and continues to be conducted through ARC Properties Operating Partnership, L.P. (the “OP”), a Delaware limited partnership. The Company is the sole general partner and holder of 99.1% of the equity interest in the OP as of December 31, 2012. ARC Real Estate Partners, LLC (the "Contributor") and certain unaffiliated investors are limited partners and owners of 0.2% and 0.7%, respectively, of the equity interest in the OP. After holding units of limited partner interests in the OP (“OP Units”) for a period of one year, holders of OP Units have the right to convert OP Units for the cash value of a corresponding number of shares of the Company's common stock or, at the option of the OP, a corresponding number of shares of the Company's common stock, as allowed by the limited partnership agreement of the OP. All holders of units of equity ownership in the ARCT III operating partnership converted such units into the same class of equity ownership in the OP immediately upon consummation of the Merger. 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.

The Company has retained ARC Properties Advisors, LLC (the “Manager”), a wholly owned subsidiary of the Sponsor, to manage its affairs on a day to day basis and, as a result, is generally externally managed. Prior to the Merger, the Company had no employees. In connection with the Merger, the Company internalized certain functions performed for it by the Sponsor and its affiliates prior to the Merger, including acquisition, accounting and portfolio management services and, as a result, the Company currently employs individuals performing such functions. ARCT III was externally managed by American Realty Capital Advisors III, LLC (the “ARCT III Advisor”). These affiliated parties, including the Manager, the Sponsor and Realty Capital Securities, LLC (“RCS” or the “Dealer Manager”), an entity which is under common ownership with the Sponsor, have performed services for the Company and ARCT III, in exchange for which they have received compensation, fees and expense reimbursements, and will continue to receive compensation, fees and expense reimbursements for providing on-going investment oversight and management services to the Company.

Formation Transactions

At the completion of the Company's IPO, the Contributor , an affiliate of the Sponsor, contributed to the OP its indirect ownership interests in certain assets of ARC Income Properties, LLC and ARC Income Properties III, LLC (the “Contributed Companies”). Assets contributed included (1) 59 properties that are presently leased to RBS Citizens Bank, N.A. and Citizens Bank of Pennsylvania, or collectively, Citizens Bank, one property presently leased to Community Bank, N.A, or Community Bank, and one property leased to Home Depot U.S.A., Inc., or Home Depot, and (2) two vacant properties. Additionally, the OP assumed certain liabilities of the Contributed Companies, including $30.6 million of unsecured notes payable and $96.2 million of mortgage notes secured by the contributed properties.

Because the contribution was from an affiliate of the Sponsor and deemed to be a transaction between entities under common control, the assets and liabilities were recorded by the Company at the Contributor's carrying amount, or book value, at the time of the contribution. The assets and liabilities of the Contributed Companies are summarized as follows (amounts in thousands):

Assets and liabilities of Contributed Companies, at carryover basis:
Real estate investments, net of accumulated depreciation and amortization of $13,453	$	108,759
Other assets	2,402
Notes payable(1)	(30,626		)
Mortgage notes payable(2)	(96,472		)
Other liabilities	(834		)
Net assets (liabilities) of Contributed Companies	$	(16,771	)

______________________________________________

(1)Notes payable were repaid from the proceeds of the Company's IPO concurrently with closing.

(2)$82.6 million of mortgage notes payable were refinanced with a new $51.5 million revolving credit facility and the remaining balance was repaid from the proceeds of the Company's IPO concurrently with closing of the IPO.

Common Stock

Common Stock

On August 1, 2012, the Company 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 March 31, 2013, we had issued 2.1 million shares of common stock through a follow on offering and pursuant to the ATM (as defined below) offering under the $500.0 million universal shelf registration statement. No preferred stock, debt or equity-linked security had been issued under the $500.0 million universal shelf registration statement. The resale registration statement, as amended, registers the resale of up to 1,882,248 shares of common stock issued in connection with any future conversion of certain currently outstanding restricted shares, convertible preferred stock or limited partnership interests in the OP. As of March 31, 2013, no common stock had been issued under the resale registration statement.

On March 14, 2013, the Company filed a universal automatic shelf registration statement and achieved well-known seasoned issuer (“WKSI”) status. The Company intends to maintain both the $500.0 million universal shelf registration statement and the WKSI universal automatic shelf registration statement.

In January 2013, the Company 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 an aggregate offering proceeds of up to $60.0 million. The shares will be issued pursuant to the Company's $500.0 million universal shelf registration statement.

The following are the Company's public equity offerings of common stock (dollar amounts in millions) since inception through March 31, 2013:

Type of offering	Closing Date	Number of Shares	Gross Proceeds
IPO	September 7, 2011	5,574,131	$	67.4
Follow on offering	November 2, 2011	1,497,924	15.8
Underwriters' over allotment	November 7, 2011	74,979	0.8
Follow on offering	June 18, 2012	3,250,000	30.3
Underwriters' over allotment	July 9, 2012	487,500	4.6
Follow on offering	January 29, 2013	2,070,000	26.7
ATM	January 1 - March 31, 2013	61,000	0.8
Total		13,015,534	$	146.4

The table above excludes 140.7 million shares of common stock that was issued to the share holders of ARCT III's common stock in conjunction with the Merger.

The consolidated financial statements are presented as if the Merger had occurred prior to December 31, 2012, resulting in total common stock issued and outstanding of 179.2 million shares, including restricted shares of 0.3 million. Such calculation of the Company's common stock issued and outstanding at December 31, 2012 is based on the combination of 11.2 million shares of the Company's common stock issued and outstanding prior to the Merger, and 168.0 million shares of the Company's common stock based upon the Exchange Ratio applied on 176.9 million shares of ARCT III common stock upon consummation of the Merger, pursuant to the Merger Agreement, if all ARCT III shares were converted to Company stock.

Upon the closing of the Merger, 29.2 million shares of the then outstanding shares of ARCT III's common stock were paid in cash at $12.00 per share, which equals 27.7 million shares of the Company's common stock after the application of the Exchange Ratio. In addition, upon closing of the Merger, 148.1 million shares of ARCT III's common stock were converted to shares of Company's common stock at the Exchange Ratio, resulting in an additional 140.7 million shares of the Company's common stock outstanding after the exchange.

The Company's board of directors has authorized, and the Company began paying, dividends since October 2011 on the fifteenth day of each month to stockholders of record on the eight day of such month. Since October 2011, the board of directors of the Company has authorized the following increases in the Company's dividend.

Equity Plan

The Company has adopted the American Realty Capital Properties, Inc. Equity Plan (the “Equity Plan”), which provides for the grant of stock options, restricted shares of common stock, restricted stock units, dividend equivalent rights and other equity-based awards to the Manager, non-executive directors, officers and other employees and independent contractors, including employees or directors of the Manager and its affiliates who are providing services to the Company.

The Company 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 Manager in connection with the IPO. All such awards of shares will vest ratably on a quarterly or annual basis over a three-year period beginning on the first anniversary of the date of grant and shall provide for “distribution equivalents” with respect to this restricted stock, whether or not vested, at the same time and in the same amounts as dividends are paid to the stockholders.

In February 2013, the Company granted 325,000 restricted shares of common stock to the Manager and certain employees. These shares did not vest upon the consummation of the Merger but will vest ratably over a three-year period and shall provide for “distribution equivalents” with respect to this restricted stock, whether or not vested, at the same time and in the same amounts as dividends are paid to the stockholders.

Non-Executive Director Stock Plan (the "Director Stock Plan"), which provides for the grant of restricted shares of common stock to each of the Company's three independent directors, each of whom is a non-executive director. Awards of restricted stock will vest ratably over a five-year period following the first anniversary of the date of grant in increments of 20.0% per annum, subject to the director’s continued service on the board of directors, and shall 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 December 31, 2012, a total of 99,000 shares of common stock are reserved for issuance under the Director Stock Plan.

The fair value of restricted common stock awards under the Equity Plan and Director Stock Plan is determined on the grant date using the closing stock price on NASDAQ that day. The fair value of restricted common stock under the Equity Plan and Director Stock Plan is updated at the end of each quarter based on the quarter end closing stock price through the final vesting date.

Restricted Share Plan

ARCT III had an employee and director incentive restricted share plan (the “RSP”), which provided for the automatic grant of 3,000 restricted shares of common stock to each of its independent directors, without any further action by ARCT III’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 first anniversary of the date of grant in increments of 20.0% per annum. The RSP provided ARCT III with the ability to grant awards of restricted shares to its directors, officers and employees (if ARCT III ever had employees), employees of ARCT III's Advisor and its affiliates, employees of entities that provided services to ARCT III, directors of the ARCT III Advisor or of entities that provided services to ARCT III, certain consultants to ARCT III and the ARCT III Advisor and its affiliates or to entities that provided services to ARCT III.

The following tables detail the restricted shares activity within the Equity Plan, Director Stock Plan and RSP during the years ended December 31, 2012 and 2011:

In connection with the Merger, each share of restricted stock outstanding as of immediately prior to the effective date of the Merger became fully vested.

For the years ended December 31, 2012 and 2011, compensation expense for restricted shares was $1.2 million and $0.2 million, respectively. There was $0.1 million compensation expense for restricted shares for the year ended December 31, 2010.

Stock Option Plan

ARCT III had a stock option plan (the “Stock Option Plan”) which authorized the grant of nonqualified stock options to its independent directors, officers, advisors, consultants and other personnel, subject to the absolute discretion of its board of directors and the applicable limitations of the Stock Option Plan. The exercise price for all stock options granted under the Stock Option Plan were fixed at $10.00 per share until the ARCT III IPO terminated, and thereafter the exercise price for stock options granted to the independent directors were equal to the fair market value of a share on the last business day preceding the annual meeting of stockholders. A total of 0.5 million shares had been authorized and reserved for issuance under the Stock Option Plan. As of December 31, 2012 and 2011, no stock options were issued under the Stock Option Plan. The Stock Option Plan was terminated in February 2013.

Multi-Year Performance Plan

Upon consummation of the Merger, the Company entered into the 2013 Advisor Multi-Year Outperformance Agreement (the “OPP”) with the Manager, whereby the Manager will be able to potentially earn compensation upon the attainment of stockholder value creation targets.

Under the OPP, the manager was granted 8,241,101 long term incentive plan units ("LTIP Units") of the OP, which will be earned or forfeited based on the Company's total return to stockholders (including both share price appreciation and common stock distributions) ("Total Return"), for the three year period consisting of:

• Absolute Component: 4.0% of any excess Total Return attained above an absolute hurdle of 7.0% for each annual measurement period, non-compounded, 14.0% for the interim measurement period and 21.0% for the full performance period; and

• Relative Component: 4.0% of any excess Total Return attained above the Total Return for the performance period of a peer group comprised of the following companies: CapLease, Inc.; EPR Properties; Getty Realty Corporation; Lexington Realty Trust; National Retail Properties, Inc.; and Realty Income Corporation.

The award will be funded ("OPP Pool") up to a maximum award opportunity equal to 5% of the Company's equity market capitalization at the Merger date of $2.1 billion (the "OPP Cap"). Awards under the OPP are dependent on achieving an annual hurdle, that commenced December 11, 2012, an interim (two-year) hurdle and then the aforementioned three-year hurdle ending on December 31, 2015.

In order to further ensure that the interests of the Manager are aligned with the Company's investors, the Relative Component is subject to a ratable sliding scale factor as follows:

• 100.0% will be earned if the Company attains a median Total Return of at least 6.0% for each annual measurement period, non-compounded, at least 12.0% for the interim measurement period, and at least 18.0% for the full performance period;

• 50.0% will be earned if the Company attains a median Total Return of at least 0.0% for each measurement period;

• 0.0% will be earned if the Company attains a median Total Return of less than 0.0% for each measurement period; and

• A percentage from 50.0% to 100.0% calculated by linear interpolation will be earned if the Company's median Total Return is between 0.0% and th percentage set for each measurement period.

For each year during the performance period a portion of the OPP Cap equal to a maximum of up to 1.25% of the Company's equity market capitalization of $2.1 billion will be “locked-in” based upon the attainment of the performance hurdles set forth above for each annual measurement period. In addition, a portion of the OPP Cap equal to a maximum of up to 3.0% of the Company's equity market capitalization will be “locked-in” based upon the attainment of the performance hurdles set forth above for the interim measurement period, which if achieved, will supersede and negate any prior “locked-in” portion based upon annual performance through December 31, 2013 and 2014 (i.e., a maximum award opportunity equal to a maximum of up to 3.0% of the Company's equity market capitalization may be “locked-in” through December 31. 2014).

Following the performance period, the Absolute Component and the Relative Component will be calculated separately and then added together to determine the aggregate award earned under the OPP, which will be the lesser of the sum of the two components and the OPP Cap. The OPP Pool will be used to determine the number of LTIP units that vest. Any unvested LTIP units will be immediately forfeited on December 31, 2015. At March 31, 2013, 100% of the pool has been allocated.

The Manager will be entitled to convert 33.3% of the LTIP units earned into OP Units on each of December 31, 2015, 2016 and 2017 and within 30 days following such date. In addition, the OPP provides for accelerated earning and vesting of LTIP Units and redemption of vested LTIP Units for cash if the Manager is terminated or if the Company experiences a change in control. The Manager will be entitled to receive a tax gross-up in the event that any amounts paid to it under the OPP constitute “parachute payments” as defined in Section 280G of the Internal Revenue Code of 1986, as amended (the "Code").

The fair value of the LTIP Units granted are being amortized over the performance period. The Company did not incur expenses for the OPP during the years ended December 31, 2012 and 2011, respectively.

Other Share-Based Compensation

ARCT III was permitted to issue common stock in lieu of cash to pay fees earned by its directors, at the respective director's election. There were no restrictions on the shares issued since these payments in lieu of cash relate to fees earned for services performed. The following table reflects the shares of ARCT III common stock issued to directors in lieu of cash compensation (dollar amounts in thousands):

Senior Secured Revolving Credit Facility

12 Months Ended

Dec. 31, 2012

Line of Credit Facility [Abstract]

Senor Secured Revolving Credit Facility [Text Block]

Credit Facilities

On September 7, 2011, the Company obtained a senior secured revolving credit facility with RBS of up to $150.0 million subject to providing qualified collateral, among other conditions. The proceeds of advances made under the credit agreement may have been used to finance the acquisition of net leased, investment or non-investment grade leased properties and for other permitted corporate purposes. Up to $10.0 million of the facility was available for letters of credit. The credit agreement had a term of 36 months and a maturity date of September 7, 2014, and could have been be extended at the Company's option for an additional 24 months.

Any advance made under the credit facility bore floating interest at per annum rates equal to the one-month London Interbank Offered Rate (“LIBOR”) plus 2.15% to 2.90% depending on the Company's loan to value ratio as specified in the credit agreement. In the event of a default, the lender had the right to terminate its obligations under the credit agreement, including the funding of future advances, and to accelerate the payment on any unpaid principal amounts outstanding. The credit facility required a fee of 0.15% on the unused balance if amounts outstanding under the facility are 50% or more of the total facility amount and 0.25% on the unused balance if amounts outstanding under the facility were less than 50% of the total facility amount.

As of December 31, 2012, there was $124.6 million outstanding on this facility, which bore an interest rate of 3.11%, collateralized by 114 properties. At December 31, 2012, there was $20.4 million available to the Company for future borrowings. At December 31, 2011, there was $42.4 million outstanding on this facility with an interest rate of 3.17%, collateralized by 59 properties. In conjunction with the Merger the credit facility was repaid in full and terminated.

On July 20, 2012, ARCT III, through ARCT III OP, entered into a senior revolving credit facility (the “Senior Facility”) in the amount of $100.0 million with RBS. The Senior Facility had a term of 36 months and a maturity date in July 2015, and could have been extended for an additional 12 months. ARCT III had the option, based upon its corporate leverage, to draw loans under the Senior Facility priced at either: (a) LIBOR, plus an applicable margin that ranges from 2.10% to 3.50%; or (b) the Base Rate, plus an applicable margin that ranges from 2.50% to 3.00%. Base Rate is defined in the Senior Facility agreement as the greater of (i) the fluctuating annual rate of interest announced from time to time by RBS as its “prime rate” or (ii) 1.0% above the federal funds effective rate. The Senior Facility included an unused fee per annum of 0.25% and 0.15%, if the unused balance of the Senior Facility exceeded or was less than 50% of the available facility, respectively.

The Senior Facility provided for monthly interest payments, with all principal outstanding being due on the maturity date. Borrowings under the Senior Facility were permitted to be prepaid from time to time and at any time, in whole or in part, without premium or penalty, subject to reimbursement of certain costs and expenses. In the event of a default, each lender had the right to terminate its obligations under the Senior Facility, and to accelerate the payment on any unpaid principal amount of all outstanding loans. ARCT III had guaranteed the obligations under the Senior Facility. The Senior Facility required ARCT III to meet certain financial covenants, including the maintenance of certain financial ratios (such as specified debt to equity and debt service coverage ratios) as well as the maintenance of a minimum net worth. As of December 31, 2012, ARCT III was in compliance with the debt covenants under the Senior Facility agreement.

As of December 31, 2012, ARCT III had no outstanding borrowings under the Senior Facility. ARCT III incurred $0.1 million in unused fees during the year ended December 31, 2012.

On February 14, 2013, simultaneous with ARCT III entering into the New Credit Facility, ARCT III terminated the Senior Facility agreement with RBS.

The Company’s sources of financing generally require financial covenants, as well as restrictions on corporate guarantees, the maintenance of certain financial ratios (such as specified debt to equity and debt service coverage ratios) as well as the maintenance of a minimum net worth. At December 31, 2012 and 2011, the Company was in compliance with the debt covenants under the RBS Facility agreement.

New Credit Facility

On February14, 2013, ARCT III, entered into the New Credit Facility with Wells Fargo Bank, National Association, as administrative agent, RBS and Regions Bank, as syndication agents, and Capital One, N.A. and JP Morgan Chase Bank, N.A., as documentation agents. Since that date the facility has been augmented to increase the commitments of certain lenders and add Bank of America N.A., Barclays Bank PLC, TD Bank N.A., U.S. Bank N.A., Union Bank N.A., UBS AG, Comerica Bank and First Tennessee Bank, as lenders.

These additional commitments increased the facility to $1.45 billion. The New Credit Facility has an accordion feature, which if exercised in full, the aggregate commitments (comprised of revolving, term loan and delayed draw commitments) under the credit agreement would be $2.5 billion, subject to borrowing base availability.

The New Credit Facility contains a $810.0 million term loan facility and a $640.0 million revolving credit facility. Loans under the New Credit Facility are priced at a floating interest rate of LIBOR plus 1.60% to 2.20%, based upon the Company’s current leverage. To the extent that the Company receives an investment grade credit rating as determined by a major credit rating agency, at the Company's election, advances under the New Credit Facility will be priced at their applicable rate plus 0.90% to 1.75% and term loans will be priced at a floating interest rate of LIBOR plus 1.15% to 2.00%, based upon the Company’s then current investment grade credit rating. The Company may also make fixed rate borrowings under the New Credit Facility.

The New Credit Facility provides for monthly interest payments. In the event of a default, each lender has the right to terminate its obligations under the credit facility, and to accelerate the payment on any unpaid principal amount of all outstanding loans. The Company has guaranteed the obligations under the credit facility. The revolving credit facility will terminate on February 14, 2017, unless extended, to which the term loan facility will terminate on February 14, 2018. The Company may prepay borrowings under the New Credit Facility and, to the extent that borrowings are unused under the revolving credit facility and the term loan facility, the Company incurs an unused fee of 0.15% to 0.25% per annum on the unused amount depending on the unused balance as a percentage of the total facility and the type of funding. The New Credit Facility also requires the Company to maintain certain property available for collateral as a condition to funding.

Discontinued Operations and Properties Held for Sale

The Company separately classifies properties held for sale in the accompanying consolidated balance sheets and operating results for those properties as discontinued operations in the accompanying consolidated statements of operations and comprehensive loss. In the normal course of business, changes in the market may compel the Company to decide to classify a property as held for sale or reclassify a property that is designated as held for sale back to held for investment. In these situations, the property is transferred to held for sale or back to held for investment at the lesser of fair value or depreciated cost. As of December 31, 2012 and 2011, the Company held one and two vacant properties, respectively, which were classified as held for sale on the accompanying respective consolidated balance sheets.

On July 1, 2012, the Company sold one of the vacant properties, which was located in Havertown, PA, for net proceeds of $0.6 million and recorded a loss on held for sale properties of $0.5 million. Additionally, in 2012, the Company recorded an impairment on assets held for sale of $0.1 million on its remaining property classified as held for sale.

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:

Since the announcement of the Merger Agreement on December 17, 2012, Randell Quaal filed a putative class action lawsuit filed on January 19, 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 lawsuit alleges, among other things, that the board of ARCT III breached its fiduciary duties in connection with the transactions contemplated under the 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 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.

The Company maintains directors and officers liability insurance which the Company believes should provide coverage to the Company and its officers and directors for most or all of any costs, settlements or judgments resulting from the lawsuit.

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.

Derivatives and Hedging Activities

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

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 caps 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 caps designated as cash flow hedges involve the receipt of variable-rate amounts if interest rates rise above the cap 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. Such derivatives are used to hedge the variable cash flows associated with forecasted 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 $1.5 million will be reclassified from other comprehensive income as an increase to interest expense.

As of December 31, 2012 , 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	Balance Sheet Location	Number of Instruments	Notional Amount
Interest Rate Swaps	Derivatives, at fair value	7	$	152,590

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 December 31, 2012, the fair value of the derivatives in a net liability position, including accrued interest but excluding any adjustment for nonperformance risk related to these agreements was $4.1 million. As of December 31, 2012, 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 $4.1 million at December 31, 2012.

Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure [Text Block]

Investment Securities

At December 31, 2012, the Company had investments in redeemable preferred stock and senior notes, accounted for as debt securities, with a fair value of $41.7 million. These investments were considered available-for-sale securities and therefore increases or decreases in the fair value of these investments are recorded in accumulated other comprehensive income as a component of equity on the consolidated balance sheet unless the securities are considered to be permanently impaired at which time the losses are reclassified to expense.

The following table details the unrealized gains and losses on investment securities as of December 31, 2012. The Company did not have any such investments as of December 31, 2011 (amounts in thousands):

	December 31, 2012
	Cost		Gross Unrealized Gains		Gross Unrealized Losses			Fair Value
Investment securities	$	41,747	$	223	$	(316	)	$	41,654

The Company’s preferred stock investments were redeemable at the respective issuer’s option after five years from issuance. The senior notes had a weighted-average maturity of 29.6 years and a weighted-average interest rate of 5.7% as of December 31, 2012. These investments were sold in February 2013.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

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 rare.

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 December 31, 2012, 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. The Company’s interest rate cap derivative measured at fair value on a recurring basis as of December 31, 2012 was zero and was classified in Level 2 of the fair value hierarchy.

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.

The Company's preferred units, senior note investments and common stock are in active markets and therefore, due to the availability of quoted market prices in active markets, classified these investments as Level 1 in the fair value hierarchy.

The following table presents information about the Company’s assets and liabilities (including derivatives that are presented net) measured at fair value on a recurring basis as of December 31, 2012 and 2011, aggregated by the level in the fair value hierarchy within which those instruments fall (amounts in thousands):

	Quoted Prices in Active Markets Level 1		Significant Other Observable Inputs Level 2			Significant Unobservable Inputs Level 3		Total
December 31, 2012
Investment securities	$	41,654	$	—		$	—	$	41,654

December 31, 2011
Interest rate swap	$	—	$	(98	)	$	—	$	(98	)

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 of the fair value hierarchy during the year ended December 31, 2012.

The Company is required to disclose the fair value of financial instruments for which it is practicable to estimate that value. The fair value of short-term financial instruments such as cash and cash equivalents, due to affiliates and accounts payable approximate their carrying value on the accompanying consolidated balance sheets due to their short-term nature.

The fair values of the Company’s financial instruments that are not reported at fair value on the consolidated balance sheets are reported below (amounts in thousands):

		Carrying Amount at		Fair Value at		Carrying Amount at		Fair Value at
	Level	December 31, 2012		December 31, 2012		December 31, 2011		December 31, 2011
Mortgage notes payable	3	$	265,118	$	271,056	$	35,320	$	35,686
Senior secured revolving credit facility	3	$	124,604	$	124,604	$	42,407	$	42,407

The fair value of mortgage notes payable are obtained by calculating the present value at current market rates. The terms of the RBS Facility and the Company's level ratio are considered commensurate with the market, as such the outstanding balance on the facility approximates fair value.

Accounting Policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

Basis of Accounting

The accompanying consolidated financial statements are prepared on the accrual basis of accounting in accordance with U.S. GAAP.

Deferred Charges, Policy [Policy Text Block]

Deferred Costs, Net

Deferred costs, net consists of deferred financing costs net of accumulated amortization, deferred leasing costs net of accumulated amortization and deferred offering costs.

Deferred financing costs represent commitment fees, legal fees, and other costs associated with obtaining commitments for financing. These costs are amortized over the terms of the respective financing agreements using the effective interest method. Unamortized deferred financing costs are expensed when the associated debt is refinanced or repaid before maturity. Costs incurred in seeking financial transactions that do not close are expensed in the period in which it is determined the financing will not close. At December 31, 2012 and 2011, the Company had $15.1 million and $3.1 million, respectively, of deferred financing costs net of accumulated amortization.

Deferred leasing costs, consisting primarily of lease commissions and payments made to assume existing leases, are deferred and amortized over the term of the lease. At December 31, 2012 and 2011, the Company had $0.2 million and $0.3 million, respectively, of deferred leasing costs, net of accumulated amortization.

Deferred offering costs represent professional fees, fees paid to various regulatory agencies, and other costs incurred in connection with registering to sell shares of the Company's common stock. As of December 31, 2012, the Company had $0.1 million of deferred offering costs related to the Company's $500.0 million universal shelf and resale registration statements filed with the SEC in August 2012. As of December 31, 2011, the Company had no deferred offering costs.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board (the “FASB”) issued guidance that expands the existing disclosure requirements for fair value measurements, primarily for Level 3 measurements, which are measurements based on unobservable inputs such as the Company’s own data. This guidance is largely consistent with current fair value measurement principles with few exceptions that do not result in a change in general practice. The guidance was applied prospectively and was effective for interim and annual reporting periods ending after December 15, 2011. The adoption of this guidance did not have a material impact on the Company’s financial position or results of operations as the guidance relates only to disclosure requirements.

In June 2011, the FASB issued guidance requiring entities to present items of net income and other comprehensive income either in one continuous statement – referred to as the statement of comprehensive income – or in two separate, but consecutive, statements of net income and other comprehensive income. The new guidance does not change which components of comprehensive income are recognized in net income or other comprehensive income, or when an item of other comprehensive income must be reclassified to net income. In December 2011, the FASB deferred certain provisions of this guidance related to the presentation of certain reclassification adjustments out of accumulated other comprehensive income, by component in both the statement and the statement where the reclassification is presented. This guidance was applied prospectively and was effective for interim and annual reporting periods ended after December 15, 2011. The adoption of this guidance did not have a material impact on the Company’s financial position or results of operations but changed the location of the presentation of other comprehensive income to more closely associate the disclosure with net income.

In September 2011, the FASB issued guidance that allows entities to perform a qualitative analysis as the first step in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If it is determined that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then a quantitative analysis for impairment is not required. The guidance was effective for interim and annual impairment tests for fiscal periods beginning after December 15, 2011. The adoption of this guidance did not have a material impact on the Company's financial position or results of operations.

In December 2011, the FASB issued guidance which contains new disclosure requirements regarding the nature of and entity's rights of offset and related arrangements associated with its financial instruments and derivative instruments. The new disclosures are designed to make financial statements prepared under U.S. GAAP more comparable to those prepared under International Financial Reporting Standards and will give the financial statement users information about both gross and net exposures. The guidance is effective for interim and annual reporting periods beginning on or after January 1, 2013. The adoption of this guidance is not expected to have a material impact on the Company's financial position or results of operations.

In July 2012, the FASB issued revised guidance intended to simplify how an entity tests indefinite-lived intangible assets for impairment. The amendments will allow an entity first to assess qualitative factors to determine whether it is necessary to perform a quantitative impairment test. An entity will no longer be required to calculate the fair value of an indefinite-lived intangible asset and perform the quantitative test unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The amendments are effective for annual and interim indefinite-lived intangible asset impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption was permitted. The adoption of this guidance did not have a material impact on the Company's consolidated financial position, results of operations, or cash flows.

In February 2013, the FASB issued guidance which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The guidance is effective for annual and interim periods beginning after December 15, 2012 with early adoption permitted. The adoption of this guidance, which is related to disclosure only, did not have a material impact on the Company's consolidated financial position, results of operations or cash flows.

Principles of Consolidation and Basis of Presentation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. In determining whether the Company has a controlling financial interest in a joint venture and the requirement to consolidate the accounts of that entity, management considers factors such as ownership interest, authority to make decisions and contractual and substantive participating rights of the other partners or members as well as whether the entity is a variable interest entity for which the Company is the primary beneficiary.

Reclassification, Policy [Policy Text Block]

Reclassification

Certain reclassifications have been made to the previously issued historical consolidated financial statements of the Company and ARCT III to conform to this consolidated presentation.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Management makes significant estimates regarding revenue recognition, to record investments in real estate, real estate taxes, and derivative financial instruments and hedging activities, as applicable.

Development Stage Company [Policy Text Block]

Formation Transactions

Upon the effectiveness of the IPO, the Company acquired certain properties from affiliated entities of the Company and, as such, the Company was no longer considered to be in the development stage. The contribution of the properties from affiliates in the initial formation of the Company was accounted for as a reorganization of entities under common control and therefore all assets and liabilities related to the contributed properties were accounted for on the carryover basis of accounting whereby the real estate investments were contributed at amortized cost and all assets and liabilities of the predecessor entities became assets and liabilities of the Company.

Real Estate, Policy [Policy Text Block]

Real Estate Investments

The Company records acquired real estate at cost and makes assessments as to the useful lives of depreciable assets. The Company considers the period of future benefit of the asset to determine the appropriate useful lives. Depreciation is computed using a straight-line method over the estimated useful life of 40 years for buildings, five to 15 years for building fixtures and improvements and the remaining lease term for acquired intangible lease assets.

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

Impairment of Long Lived Assets

Operations related to properties that have been sold or properties that are intended to be sold are presented as discontinued operations in the statement of operations for all periods presented, and properties intended to be sold are designated as “held for sale” on the accompanying consolidated balance sheets.

When circumstances indicate the carrying value of a property may not be recoverable, the Company reviews the asset for impairment. This review is based on an estimate of the future undiscounted cash flows, excluding interest charges, expected to result from the property’s use and eventual disposition. These estimates consider factors such as expected future operating income, market and other applicable trends and residual value, as well as the effects of leasing demand, competition and other factors. If impairment exists, due to the inability to recover the carrying value of a property, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair value of the property for properties to be held and used.

For properties held for sale, the impairment loss is the adjustment to fair value less estimated cost to dispose of the asset. These assessments have a direct impact on net income because recording an impairment loss results in an immediate negative adjustment to net income. At December 31, 2012, and 2011, the Company had one and two, respectively, vacant properties classified as properties held for sale. See Note 17 — Discontinued Operations and Properties Held for Sale.

Allocation of Purchase Price of Acquired Assets [Policy Text Block]

Allocation of Purchase Price of Acquired Assets

The Company allocates the purchase price of acquired properties to tangible and identifiable intangible assets acquired based on their respective fair values. Tangible assets include land, buildings, equipment and tenant improvements on an as-if vacant basis. The Company utilizes various estimates, processes and information to determine the as-if vacant property value. Estimates of value are made using customary methods, including data from appraisals, comparable sales, discounted cash flow analysis and other methods. Identifiable intangible assets include amounts allocated to acquire leases for above- and below-market lease rates, the value of in-place leases, and the value of customer relationships.

Amounts allocated to land, buildings, equipment and fixtures are based on cost segregation studies performed by independent third-parties or on the Company's analysis of comparable properties in its portfolio. Depreciation is computed using the straight-line method over the estimated lives of forty years for buildings, five to ten years for building equipment and fixtures, and the shorter of the useful life or the remaining lease term for tenant improvements.

The aggregate value of intangible assets related to in-place leases is primarily the difference between the property valued with existing in-place leases adjusted to market rental rates and the property valued as if vacant. Factors considered by the Company in its analysis of the in-place lease intangibles include an estimate of carrying costs during the expected lease-up period for each property, taking into account current market conditions and costs to execute similar leases. In estimating carrying costs, the Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up period, which typically ranges from six to 18 months. The Company also estimates costs to execute similar leases including leasing commissions, legal and other related expenses.

Above-market and below-market in-place lease values for owned properties are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between the contractual amounts to be paid pursuant to the in-place leases and management's estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. The capitalized above-market lease intangibles are amortized as a decrease to rental income over the remaining term of the lease. The capitalized below-market lease values will be amortized as an increase to rental income over the remaining term and any fixed rate renewal periods provided within the respective leases. In determining the amortization period for below-market lease intangibles, the Company initially will consider, and periodically evaluate on a quarterly basis, the likelihood that a lessee will execute the renewal option. The likelihood that a lessee will execute the renewal option is determined by taking into consideration the tenant's payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area in which the property is located.

The aggregate value of intangibles assets related to customer relationships is measured based on the Company's evaluation of the specific characteristics of each tenant's lease and the Company's overall relationship with the tenant. Characteristics considered by the Company in determining these values include the nature and extent of the Company's existing business relationships with the tenant, growth prospects for developing new business with the tenant, the tenant's credit quality and expectations of lease renewals, among other factors.

The value of in-place leases is amortized to expense over the initial term of the respective leases, which range primarily from 2 to 20 years. The value of customer relationship intangibles is amortized to expense over the initial term and any renewal periods in the respective leases, but in no event does the amortization period for intangible assets exceed the remaining depreciable life of the building. If a tenant terminates its lease, the unamortized portion of the in-place lease value and customer relationship intangibles is charged to expense.

In making estimates of fair values for purposes of allocating purchase price, the Company utilizes a number of sources, including independent appraisals that may be obtained in connection with the acquisition or financing of the respective property and other market data. The Company also considers information obtained about each property as a result of its pre-acquisition due diligence, as well as subsequent marketing and leasing activities, in estimating the fair value of the tangible and intangible assets acquired and intangible liabilities assumed.

Intangible lease assets of the Company consist of the following as of December 31, 2012 and 2011 (amounts in thousands):

	December 31,
	2012			2011
In-place leases, gross	$	210,959		$	21,777

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

Cash and cash equivalents include cash in bank accounts as well as investments in highly-liquid money market funds with original maturities of three months or less.

The Company deposits cash with high quality financial institutions. These deposits are guaranteed by the Federal Deposit Insurance Company (“FDIC”) up to an insurance limit. At December 31, 2012 and 2011, the Company had deposits of $156.9 million and $19.3 million, respectively, of which $154.8 million and $18.5 million were in excess of the amount insured by the FDIC. Although the Company bears risk to amounts in excess of those insured by the FDIC, it does not anticipate any losses as a result.

Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]

Restricted Cash

Restricted cash primarily consists of reserves related to lease expirations as well as maintenance, structural, and debt service reserves.

Derivatives, Policy [Policy Text Block]

Derivative Instruments

The Company may use derivative financial instruments to hedge all or a portion of the interest rate risk associated with its borrowings. Certain of the techniques used to hedge exposure to interest rate fluctuations may also be used to protect against declines in the market value of assets that result from general trends in debt markets. The principal objective of such agreements 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 records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

The accounting for subsequent changes in the fair value of these derivatives depends on whether each has been designed and qualifies for hedge accounting treatment. If the Company elects not to apply hedge accounting treatment, any changes in the fair value of these derivative instruments is recognized immediately in gains (losses) on derivative instruments in the consolidated statement of operations. If the derivative is designated and qualifies for hedge accounting treatment the change in the estimated fair value of the derivative is recorded in other comprehensive income (loss) to the extent that it is effective. Any ineffective portion of a derivative's change in fair value will be immediately recognized in earnings.

Revenue Recognition, Policy [Policy Text Block]

Revenue Recognition

Upon the acquisition of real estate, certain properties will have leases where minimum rent payments increase during the term of the lease. The Company will record rental revenue for the full term of each lease on a straight-line basis. When the Company acquires a property, the term of existing leases is considered to commence as of the acquisition date for the purposes of this calculation. Cost recoveries from tenants are included in tenant reimbursement income in the period the related costs are incurred, as applicable.

The Company's revenues, which are derived primarily from rental income, include rents that each tenant pays in accordance with the terms of each lease reported on a straight-line basis over the initial term of the lease. Since many of the leases provide for rental increases at specified intervals, straight-line basis accounting requires the Company to record a receivable, and include in revenues, unbilled rent receivables that the Company will only receive if the tenant makes all rent payments required through the expiration of the initial term of the lease. The Company defers the revenue related to lease payments received from tenants in advance of their due dates.

The Company continually reviews receivables related to rent and unbilled rent receivables and determines collectability by taking into consideration the tenant's payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area in which the property is located. In the event that the collectability of a receivable is in doubt, the Company will record an increase in the allowance for uncollectible accounts or record a direct write-off of the receivable in the consolidated statements of operations and comprehensive loss. As of December 31, 2012 and 2011, the Company determined that there was no allowance for uncollectible accounts necessary.

Offering and Related Costs Policy [Policy Text Block]

Offering and Related Costs

Offering and related costs include costs incurred in connection with the Company's issuance of common stock. These costs include, but are not limited to, (i) legal, accounting, printing, mailing and filing fees; (ii) escrow related fees, and (iii) reimbursement to the Dealer Manager for amounts they paid to reimburse the bonified due diligence expenses of broker-dealers.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Share-Based Compensation

The Company has a stock-based incentive award plan for its affiliated Manager, non-executive directors, officers, other employees and independent contractors who are providing services to the Company, as applicable, and a non-executive director restricted share plan, which are accounted for under the guidance for share-based payments. The expense for such awards is included in general and administrative expenses and is recognized over the vesting period or when the requirements for exercise of the award have been met. See Note 12 — Share-Based Compensation for additional information on these plans.

Income Tax, Policy [Policy Text Block]

Income Taxes

Each of the Company and ARCT III qualified as REITs under Sections 856 through 860 of the Internal Revenue Code (the “Code”) commencing with the taxable year ended December 31, 2011. Being qualified for taxation as a REIT, each of the Company and ARCT III generally will not be subject to federal corporate income tax to the extent it distributes its REIT taxable income to its stockholders, and so long as it distributes at least 90% of its REIT taxable income. REITs are subject to a number of other organizational and operational requirements. Each of the Company and ARCT III may still be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed income.

Earnings Per Share, Policy [Policy Text Block]

Per Share Data

Income (loss) per basic share of common stock is calculated by dividing net income (loss) less dividends on unvested restricted stock and dividends on preferred shares by the weighted-average number of shares of common stock issued and outstanding during such period. Diluted income (loss) per share of common stock considers the effect of potentially dilutive shares of common stock outstanding during the period.

Segment Reporting, Policy [Policy Text Block]

Reportable Segments

The Company has determined that it has one reportable segment, with activities related to investing in real estate. The Company's investments in real estate generate rental revenue and other income through the leasing of properties, which comprised 100% of its total consolidated revenues. Although the Company's investments in real estate will be geographically diversified throughout the United States, management evaluates operating performance on an individual property level. The Company's properties have been aggregated into one reportable segment.

Share Repurchase Program [Policy Text Block]

Share Repurchase Program

ARCT III's board of directors had adopted a Share Repurchase Program (“SRP”) that enabled stockholders to sell their shares to ARCT III in limited circumstances. The SRP permitted investors to sell their shares back to ARCT III after they had held them for at least one year, subject to the significant conditions and limitations described below.

The purchase price per share depended on the length of time investors had held such shares as follows: after one year from the purchase date — the lower of $9.25 or 92.5% of the amount they actually paid for each share; after two years from the purchase date —the lower of $9.50 or 95.0% of the amount they actually paid for each share; after three years from the purchase date — the lower of $9.75 or 97.5% of the amount they actually paid for each share; and after four years from the purchase date — the lower of $10.00 or 100% of the amount they actually paid for each share.

ARCT III was only authorized to repurchase shares pursuant to the SRP up to the value of shares issued under the DRIP and limited the amount spent to repurchase shares in a given quarter to the value of the shares issued under the DRIP in that same quarter.

When a stockholder requested repurchases and the repurchases were approved by ARCT III’s board of directors, it reclassified such obligation from equity to a liability based on the settlement value of the obligation. The following table reflects the number of shares repurchased for the years ended December 31, 2012 and 2011. There were no repurchases requested or fulfilled during the period from October 15, 2010 (“ARCT III's date of inception”) to December 31, 2010.

Year ended December 31,	Number of Requests	Number of Shares	Average Price per Share
2011	1	2,375	$	10.00
2012	73	179,104	9.93
Cumulative repurchase requests as of December 31, 2012 (1)	74	181,479	$	9.93

_____________________________

(1) Includes unfulfilled repurchase requests for 35,180 shares at a average price per share of $9.86, which were approved for repurchase as of December 31, 2012.

Upon the Merger the SRP was terminated.

Distribution reinvestment Plan, policy [Policy Text Block]

Distribution Reinvestment Plan

Pursuant to the ARCT III distribution reinvestment plan or ("DRIP"), stockholders could have elected to reinvest distributions by purchasing shares of ARCT III common stock in lieu of receiving cash.  No dealer manager fees or selling commissions were paid with respect to shares purchased pursuant to the DRIP.  Participants purchasing shares pursuant to the DRIP had the same rights and were treated in the same manner as if such shares were issued pursuant to ARCT III's initial public offering (the "ARCT III IPO"). Shares issued under the DRIP were recorded within stockholders’ equity in the accompanying consolidated balance sheets in the period distributions were declared. During the years ended December 31, 2012 and 2011, ARCT III issued 2.7 million and 27,169 shares of common stock, respectively, with a value of $26.8 million and $0.3 million, respectively, in each case with a par value per share of $0.01, pursuant to the DRIP. Upon the Merger, the DRIP was terminated.

Fees Paid in Connection with Common Stock Offerings

RCS received selling commissions of 6% of the gross offering proceeds from the sale of the Company’s common stock in the IPO. In addition, RCS received dealer manager fees of 2% of the gross offering proceeds before reallowance to participating broker-dealers in the IPO.

RCS received a selling commission of up to 7% of gross offering proceeds before reallowance of commissions earned by participating broker-dealers in the ARCT III IPO. In addition, RCS received up to 3% of the gross proceeds from the sale of common stock, before reallowance to participating broker-dealers, as a dealer-manager fee in the ARCT III IPO.

Fees Paid in Connection With the Operations of the Company

Each of the Company and ARCT III paid the Manager and the ARCT III Advisor, as applicable, an acquisition fee equal to 1.0% of the contract purchase price (including assumed indebtedness) of each property the Company or ARCT III, as applicable, acquired. The acquisition fee was payable in cash at the closing of each acquisition. In conjunction with the Merger, it was agreed that these fees would no longer be paid to either party. Acquisition fees are recorded in acquisition related costs in the consolidated statement of operations.

Each of the Company and ARCT III paid the Manager and the ARCT III Advisor, as applicable, a financing fee equal to 0.75% of the amount available under any secured mortgage financing or refinancing that the Company or ARCT III, as applicable, obtained and used for the acquisition of properties that was arranged by the Manager or ARCT III Advisor, as applicable. The financing coordination fee was payable in cash at the closing of each financing. In conjunction with the Merger, it was agreed that these fees would no longer be paid to either party. Financing fees are recorded in deferred costs on the consolidated balance sheet and amortized to interest expense over the term of the related debt.

The Company paid the Manager an annual base management fee equal to 0.50% per annum of the average unadjusted book value of the Company's real estate assets, calculated and payable monthly in advance, provided that the full amount of the distributions declared by the Company for the six immediately preceding months was equal to or greater than certain net income thresholds related to our operations. Our Manager waived such portion of its management fee in excess of such thresholds. The management fee is payable in cash. In conjunction with the Merger, the base management fee was reduced to 0.40% per annum for the unadjusted book value of assets over $3.0 billion. Management fees, if accrued are recorded in Operating fees to affiliates in the consolidated statements of operations.

Until July 1, 2012, ARCT III paid the ARCT III Advisor an asset management fee of 0.75% per annum of the cost of its assets (cost includes the purchase price, acquisition expenses, capital expenditures and other customarily capitalized costs, but excludes acquisition fees) plus costs and expenses incurred by the ARCT III Advisor in providing asset management services; provided, however, that the asset management fee was reduced by any amounts payable to ARCT III's property manager as an oversight fee, such that the aggregate of the asset management fee and the oversight fee did not exceed 0.75% per annum of the cost of ARCT III's assets plus costs and expenses incurred by the ARCT III Advisor in providing asset management services. Prior to July 1, 2012, this fee was payable in monthly installments at the discretion of ARCT III's board of directors in cash, common stock or restricted stock grants, or any combination thereof. Asset management fees, if accrued are recorded in Operating fees to affiliates in the consolidated statements of operations.

Effective July 1, 2012, the payment of asset management fees in monthly installments in cash, shares or restricted stock grants, or any combination thereof to the ARCT III Advisor was eliminated. Instead, ARCT III issued (subject to periodic approval by its board of directors) to the ARCT III Advisor performance-based restricted partnership units of the ARCT III OP designated as “Class B units,” which were intended to be profits interests and to vest, and no longer be subject to forfeiture, at such time as: (x) the value of the ARCT III OP’s assets plus all distributions made equal 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”); and among other potential events, a liquidity event accrued.

The ARCT III Advisor received distributions on unvested Class B units equal to the distribution rate received on ARCT III common stock. Such distributions on issued Class B units were included as general and administrative expense in the consolidated statement of operations until the performance condition is considered probable to occur. 145,022 Class B units were approved by ARCT III's board of directors as of December 31, 2012. During January and February 2013, ARCT III's board of directors approved, and ARCT III issued, 603,599 Class B units to the ARCT III Advisor for its asset management services provided. As of December 31, 2012, ARCT III did not consider achievement of the performance condition to be probable as the shareholder vote for the Merger, which would allow vesting of these Class B Units, was not completed. The performance condition related to these Class B units was satisfied upon the completion of the Merger and expense of $9.9 million was recorded at that time. The Class B units then converted to ARCT III OP units which converted to 711,190 OP Units after the application of the Exchange Ratio. These expenses were recorded in Merger and other transaction related in the consolidated statement of operations.

The Company may be required to pay the Manager a quarterly incentive fee, calculated based on 20 percent of the excess Company annualized core earnings (as defined in the management agreement with the Manager) over the weighted average number of shares multiplied by the weighted average price per share of common stock. One half of each quarterly installment of the incentive fee will be payable in shares of common stock. The remainder of the incentive fee will be payable in cash. No such incentive fees have been paid to the Manager since inception.

ARCT III paid an affiliate of the Sponsor, unless it contracted with a third party, a property management fee of up to 2% of gross revenues from ARCT III's stand-alone single-tenant net leased properties and 4% of gross revenues from its multi-tenant properties, plus, in each case, market-based leasing commissions applicable to the geographic location of the property.  ARCT III also reimbursed the affiliate for property level expenses.  If ARCT III contracted directly with third parties for such services, it paid them customary market fees and paid the affiliated property manager, an oversight fee of up to 1.0% of the gross revenues of the property managed. Property management fees are recorded in Operating fees to affiliates in the consolidated statement of operations.

In order to facilitate the smooth transition of property management services following the consummation of the Merger, the Company, the OP and the Sponsor agreed that the Property Management and Leasing Agreement will be extended for a 60 day period following the consummation of the Merger for which the Company paid the Sponsor $2.3 million. These fees were recorded in Merger and transaction related in the consolidated statement of operations.

The Company is required to reimburse the Manager for all out-of-pocket costs actually incurred by the Manager, including without limitation, legal fees and expenses, due diligence fees and expenses, other third party fees and expenses, costs of appraisals, travel expenses, nonrefundable option payments and deposits on properties not acquired, accounting fees and expenses, title insurance premiums and other closing costs, personnel costs and miscellaneous expenses relating to the selection, acquisition and due diligence of properties. The Company's reimbursement obligation is not subject to any dollar limitation. Expenses will be reimbursed in cash on a monthly basis following the end of each month. However, the Company will not reimburse the Manager for the salaries and other compensation of its personnel. Reimbursements are recorded based on the related activity to which the expense relates.

The following table details amounts incurred by the Company or ARCT III and contractually due to the Sponsor, ARCT III Advisor or the Manager and forgiven in connection with the operations related services described above (amounts in thousands):

Under an administrative support agreement between the Company and the Sponsor, the Sponsor was to pay or reimburse the Company for its general administrative expenses, including, without limitation, legal fees, audit fees, board of directors fees, insurance, marketing and investor relation fees, until September 6, 2012, which was one year after the closing of the IPO, to the extent the amount of certain net earnings from operations thresholds, as specified in the agreement, were less than the amount of the distributions declared by the Company during this one-year period. To the extent these amounts were paid by the Sponsor, they would not be subject to reimbursement by the Company. These costs are presented net in the accompanying consolidated statements of operations and comprehensive loss.

The ARCT III Advisor provided expense support to ARCT III from time to time to assist ARCT III with operating cash flow, distributions or other operational purposes.

This amount was fully accrued as of December 31, 2012 and was paid in February 2013 in conjunction with the consummation of the merger.

ARCT III entered into an agreement with an affiliate, ARC Advisory Services, LLC, to provide support services including legal, accounting, marketing, human resources and information technology, among other services, until the earlier of the Merger closing date or one year for $0.2 million pursuant to this contract. This amount was fully accrued as of December 31, 2012 and was paid in February 2013 in conjunction with the consummation of the merger.

ARCT III entered into an agreement with affiliates RCS and ARC Advisory Services, LLC, to provide financial advisory and information agent services related to the proxy solicitation seeking approval of the Merger by ARCT III's stockholders which services are expected to be provided in the fourth and first quarters of 2012 and 2013, respectively. Services to be provided include facilitation of the preparation, distribution and accumulation and tabulation of proxy materials, stockholder, analyst and financial advisor communications and consultation on materials and communications made to the public and regulatory agencies regarding the Merger. ARCT III has agreed to pay $0.6 million pursuant to this contract. As of December 31, 2012, ARCT III has incurred $0.1 million of expenses pursuant to this agreement, which includes amounts for services provided as of that date.

The Company entered into an Asset Purchase and Sale Agreement with the Sponsor pursuant to which, concurrently with the closing of the Merger and in connection with the internalization by the Company of certain property level management and accounting activities, the Sponsor sold to the OP certain furniture, fixtures, equipment and other assets used by the Sponsor in connection with managing the property level business and operations and accounting functions of the Company and the OP, and included at the cost of such assets, for an aggregate price of $5.8 million, which includes the reimbursement of certain costs and expenses incurred by the Sponsor in connection with the Merger.

On February 28, 2013, the OP entered into a Contribution and Exchange Agreement (the "Contribution and Exchange Agreement") with the ARCT III OP and American Realty Capital III Special Limited Partnership, LLC, the holder of the special limited partner interest in the ARCT III OP (the "Special Limited Partner"). The Special Limited Partner was entitled to receive certain distributions from the ARCT III 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 III OP). The Merger constituted an "investment liquidity event," as a result of which the Special Limited Partner, in connection with management's successful attainment of the 6.0% performance hurdle and the return to ARCT III's stockholders of approximately $557.3 million in addition to their initial investment, was entitled to receive a subordinated distribution of net sales proceeds from the ARCT III OP equal to approximately $98.4 million.
