Accounting Policies [Abstract]
Organization	Organization Company Organization and Operations The Company operates as a self-administered and self-managed REIT that seeks to generate and deliver sustainable and attractive returns for stockholders by investing primarily in and managing a portfolio of single-tenant, operationally essential real estate throughout the U.S. that is generally leased on a long-term, triple-net basis to tenants operating within predominantly retail, but also office and industrial property types. Single tenant, operationally essential real estate generally refers to free-standing, commercial real estate facilities where tenants conduct activities that are essential to the generation of their sales and profits. The Company’s operations are generally carried out through the Operating Partnership. OP Holdings, one of the Corporation's wholly-owned subsidiaries, is the sole general partner and owns 1.0% of the Operating Partnership. The Corporation and a wholly-owned subsidiary are the only limited partners and together own the remaining 99.0% of the Operating Partnership. As of March 31, 2016 , our undepreciated investment in real estate and loans totaled approximately $8.25 billion , representing investments in 2,610 properties, including properties securing mortgage loans made by the Company. Of this amount, 98.8% consisted of our $8.15 billion investment in real estate, representing ownership of 2,467 properties, and the remaining 1.2% consisted of $101.6 million in commercial mortgage and other loans receivable, primarily secured by the remaining 143 properties or other related assets.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Accounting and Principles of Consolidation The accompanying unaudited consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the SEC. In the opinion of management, the unaudited consolidated financial statements include the normal, recurring adjustments necessary for a fair statement of the information required to be set forth therein. The results for interim periods are not necessarily indicative of the results for the entire year. Certain information and note disclosures, normally included in financial statements prepared in accordance with GAAP, have been condensed or omitted from these statements pursuant to SEC rules and regulations and, accordingly, these financial statements should be read in conjunction with the Company’s audited consolidated financial statements as filed with the SEC in its Annual Report on Form 10-K for the year ended December 31, 2015 . The unaudited consolidated financial statements include the accounts of the Corporation and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The Company has formed numerous special purpose entities to acquire and hold real estate encumbered by indebtedness (see Note 4). As a result, the majority of the Company’s consolidated assets are held in these wholly-owned special purpose entities. Each special purpose entity is a separate legal entity and is the sole owner of its assets and responsible for its liabilities. The assets of these special purpose entities are not available to pay, or otherwise satisfy obligations to, the creditors of any affiliate or owner of another entity unless the special purpose entities have expressly agreed and are permitted under their governing documents. At March 31, 2016 and December 31, 2015 , net assets totaling $4.38 billion and $4.57 billion , respectively, were held, and net liabilities totaling $3.07 billion and $3.19 billion , respectively, were owed by these special purpose entities and are included in the accompanying consolidated balance sheets. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Although management believes its estimates are reasonable, actual results could differ from those estimates. Segment Reporting The Company views its operations as one segment, which consists of net leasing operations. The Company has no other reportable segments. Allowance for Doubtful Accounts The Company provided for reserves for uncollectible amounts related to its rent and other tenant receivables totaling $11.8 million and $11.5 million at March 31, 2016 and December 31, 2015 , respectively, against accounts receivable balances of $26.9 million and $26.3 million , respectively. Receivables are recorded within deferred costs and other assets, net in the accompanying consolidated balance sheets. The Company established a reserve for losses of $9.9 million and $12.2 million at March 31, 2016 and December 31, 2015 , respectively, against deferred rental revenue receivables of $70.8 million and $68.0 million , respectively. Deferred rental revenue receivables are recorded within deferred costs and other assets, net in the accompanying consolidated balance sheets. Restricted Cash and Escrow Deposits Restricted cash and deposits in escrow, classified within deferred costs and other assets, net in the accompanying consolidated balance sheets consisted of the following (in thousands): March 31, December 31, Collateral deposits (1) $ 13,903 $ 14,475 Tenant improvements, repairs, and leasing commissions (2) 8,708 8,362 Master Trust Release (3) 42,670 12,091 1031 Exchange proceeds, net 2 39,869 Loan impounds (4) 1,054 1,025 Other (5) 1,178 1,823 $ 67,515 $ 77,645 (1) Funds held in reserve by lenders which can be applied at their discretion to the repayment of debt (any funds remaining on deposit after the debt is paid in full are released to the borrower). (2) Deposits held as additional collateral support by lenders to fund tenant improvements, repairs and leasing commissions incurred to secure a new tenant. (3) Proceeds from the sale of assets pledged as collateral under the Spirit Master Funding Program, which are held on deposit until a qualifying substitution is made or the funds are applied as prepayment of principal. (4) Funds held in lender controlled accounts generally used to meet future debt service or certain property operating expenses. (5) Funds held in lender controlled accounts released after scheduled debt service requirements are met. Income Taxes The Company has elected to be taxed as a REIT under the Code. As a REIT, the Company generally will not be subject to federal income tax provided it continues to satisfy certain tests concerning the Company’s sources of income, the nature of its assets, the amounts distributed to its stockholders, and the ownership of Company stock. Management believes the Company has qualified and will continue to qualify as a REIT and therefore, no provision has been made for federal income taxes in the accompanying consolidated financial statements. Even if the Company qualifies for taxation as a REIT, it may be subject to state and local income and franchise taxes, and to federal income tax and excise tax on its undistributed income. Franchise taxes are included in general and administrative expenses on the accompanying consolidated statements of operations. Taxable income from non-REIT activities managed through the Company’s taxable REIT subsidiaries are subject to federal, state, and local taxes, which are not material. Reclassifications Certain reclassifications have been made to prior period balances to conform to the current period presentation. New Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB or the SEC that are adopted by the Company as of the specified effective date. Unless otherwise discussed, these new accounting pronouncements entail technical corrections to existing guidance or affect guidance related to specialized industries or entities and therefore will have minimal, if any, impact on the Company's financial position or results of operations upon adoption. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which supersedes the existing guidance for lease accounting, Leases (Topic 840) . ASU 2016-02 requires lessees to recognize leases on their balance sheets, and leaves lessor accounting largely unchanged. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early application is permitted for all entities. ASU 2016-02 requires a modified retrospective approach for all leases existing at, or entered into after, the date of initial application, with an option to elect to use certain transition relief. The Company is currently evaluating the impact of this ASU on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting , which simplifies many aspects of accounting for share-based payment transactions under ASC Topic 718, Compensation - Stock Compensation , including income tax consequences, classification of awards as either equity or liability, forfeiture rate calculations and classification on the statement of cash flows. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted for all entities. The Company is currently evaluating the impact of this ASU on its consolidated financial statements.

Investments in and Advances to Affiliates, Schedule of Investments [Abstract]
Investments	Investments Real Estate Investments As of March 31, 2016 , the Company's gross investment in real estate properties and loans totaled approximately $8.25 billion , representing investments in 2,610 properties, including 143 properties securing mortgage loans. The gross investment is comprised of land, buildings, lease intangible assets and lease intangible liabilities, as adjusted for any impairment, and the carrying amount of loans receivable, real estate assets held under direct financing leases and real estate assets held for sale. The portfolio is geographically dispersed throughout 49 states with only one state, Texas, with a real estate investment of 12.0% , accounting for more than 10.0% of the total dollar amount of the Company’s real estate investment portfolio. The properties that the Company owns are leased to tenants under long-term operating leases that typically include one or more renewal options. The leases are generally triple-net, which provides that the lessee is responsible for the payment of all property operating expenses, including property taxes, maintenance and repairs, and insurance costs. Therefore, the Company is generally not responsible for repairs or other capital expenditures related to its properties, unless the property is not subject to a triple-net lease agreement or becomes vacant. Generally, the Company's single-tenant leases contain contractual provisions increasing the rental revenue over the term of the lease at specified dates by: (1) a fixed amount or (2) increases in CPI over a specified period (typically subject to ceilings) or (b) a fixed percentage. During the three months ended March 31, 2016 , the Company had the following real estate and loan activity, net of accumulated depreciation and amortization: Number of Properties Dollar Amount of Investments Owned (4) Financed Total Owned Financed Total (In Thousands) Gross balance, December 31, 2015 2,485 144 2,629 $ 8,199,571 $ 104,003 $ 8,303,574 Acquisitions/improvements (1) (3) 15 — 15 76,010 — 76,010 Dispositions of real estate (2) (3) (33 ) — (33 ) (113,471 ) — (113,471 ) Principal payments and payoffs — (1 ) (1 ) — (2,121 ) (2,121 ) (Impairments)/recoveries — — — (12,452 ) 324 (12,128 ) Write-off of gross lease intangibles — — — (1,771 ) — (1,771 ) Loan premium amortization and other — — — (30 ) (604 ) (634 ) Gross balance, March 31, 2016 2,467 143 2,610 $ 8,147,857 $ 101,602 $ 8,249,459 Accumulated depreciation and amortization (1,116,106 ) — (1,116,106 ) Other non-real estate assets held for sale 1,700 — 1,700 Net balance, March 31, 2016 $ 7,033,451 $ 101,602 $ 7,135,053 (1) Includes investments of $3.1 million in revenue producing capitalized expenditures, as well as $0.4 million of non-revenue producing capitalized maintenance expenditures. Capitalized maintenance expenditures are not included in the Company's investment in real estate disclosed elsewhere. (2) The total accumulated depreciation and amortization associated with dispositions of real estate was $17.3 million . (3) During the three months ended March 31, 2016 , pursuant to 1031 Exchanges, the Company sold 4 properties for $21.0 million . Of this amount, and including $39.9 million of 2015 proceeds, $60.9 million was used to partially fund 10 property acquisitions. (4) At March 31, 2016 and December 31, 2015 , 31 and 36 , respectively, of the Company's properties were vacant and in the Company’s possession; of these vacant properties, 9 and 12 , respectively, were held for sale.

In addition, the future minimum rentals do not include any contingent rentals based on a percentage of the lessees' gross sales or lease escalations based on future changes in the CPI or other stipulated reference rate. Certain of the Company’s leases contain purchase options. Most of these options are at or above fair market value at the time the option is exercisable, and none of these purchase options represent bargain purchase options.

(3) Represents the weighted average maturity based on the outstanding principal balance as of March 31, 2016 . (4) Variable-rate notes are predominantly hedged with interest rate swaps (see Note 5). (5) The Company records deferred financing costs for its 2015 Credit Facility in deferred costs and other assets, net on its consolidated balance sheets. (6) At the end of the first quarter 2016, the Company borrowed $24.0 million on short notice incurring interest charges at a higher base rate (prime rate) plus an applicable margin. These borrowings were repaid within 5 business days. Revolving Credit Facilities 2015 Credit Facility On March 31, 2015, the Operating Partnership entered into the Credit Agreement that established a new $600.0 million unsecured credit facility and terminated its secured $400.0 million 2013 Credit Facility. The 2015 Credit Facility matures on March 31, 2019 (extendable at the Operating Partnership's option to March 31, 2020, subject to satisfaction of certain requirements) and includes an accordion feature to increase the committed facility size to up to $1.0 billion , subject to satisfying certain requirements and obtaining additional lender commitments. The 2015 Credit Facility includes a $50.0 million sublimit for swingline loans and up to $60.0 million available for issuances of letters of credit. Swingline loans and letters of credit reduce availability under the 2015 Credit Facility on a dollar-for-dollar basis. On November 3, 2015, the Company entered into a first amendment to the Credit Agreement. The amendment conforms certain of the terms and covenants to those in the Term Loan Agreement, including limiting the requirement of subsidiary guaranties to material subsidiaries (as defined) meeting certain conditions. At March 31, 2016 , there were no subsidiaries meeting this requirement. Borrowings bear interest at either a specified base rate or LIBOR plus an applicable margin, at the Operating Partnership's option. As of March 31, 2016 , the 2015 Credit Facility bore interest at LIBOR plus 1.70% based on the Company's leverage and incurred non-utilization fees of 0.25% per annum. Per the amendment, the Operating Partnership’s election to change the grid pricing from leverage based to credit rating based pricing will initially require at least two credit ratings of BBB- or better from S&P or Fitch or Baa3 or better from Moody’s. Upon such an event, the 2015 Credit Facility will bear interest at a rate equal to LIBOR plus 0.875% to 1.55% per annum or a specified base rate plus 0.0% to 0.55% and requires a facility fee in an amount equal to the aggregate revolving credit commitments (whether or not utilized) multiplied by a rate equal to 0.125% to 0.30% per annum, in each case depending on the Corporation's credit rating. The Operating Partnership may voluntarily prepay the 2015 Credit Facility, in whole or in part, at any time, without premium or penalty, but subject to applicable LIBOR breakage fees, if any. Payment of the 2015 Credit Facility is unconditionally guaranteed by the Corporation and material subsidiaries that meet certain conditions (as defined in the Credit Agreement). The 2015 Credit Facility is full recourse to the Operating Partnership and the aforementioned guarantors. As a result of entering into the 2015 Credit Facility, the Company incurred origination costs of $3.9 million . These deferred financing costs are being amortized to interest expense over the remaining initial term of the 2015 Credit Facility. As of March 31, 2016 and December 31, 2015 , the unamortized deferred financing costs relating to the 2015 Credit Facility were $2.9 million and $3.2 million , respectively, and recorded in deferred costs and other assets, net on the accompanying consolidated balance sheets. As of March 31, 2016 , $24.0 million of borrowings were outstanding, $8.3 million of letters of credit were issued and $567.7 million of borrowing capacity was available under the 2015 Credit Facility. The Operating Partnership's ability to borrow under the 2015 Credit Facility is subject to ongoing compliance with a number of customary financial covenants and other customary affirmative and negative covenants. As of March 31, 2016 , the Corporation and the Operating Partnership were in compliance with these financial covenants. 2013 Credit Facility On March 31, 2015, the secured 2013 Credit Facility was terminated and its outstanding borrowings were repaid with proceeds from the 2015 Credit Facility. Properties securing this facility became unencumbered upon its termination. The 2013 Credit Facility's borrowing margin was LIBOR plus 2.50% based on the Company's leverage, with an unused fee of 0.35% . Upon terminating the 2013 Credit Facility, the Company recognized debt extinguishment costs of $2.0 million , resulting from the write-off of unamortized deferred financing costs. Line of Credit A special purpose entity indirectly owned by the Corporation had access to a $40.0 million secured revolving line of credit, which expired on March 27, 2016. Term Loan On November 3, 2015, the Company entered into a Term Loan Agreement among the Operating Partnership, as borrower, the Company as guarantor and the lenders that are parties thereto. The Term Loan Agreement provides for a $325.0 million senior unsecured term facility that has an initial maturity date of November 2, 2018, which may be extended at the Company's option pursuant to two one-year extension options, subject to the satisfaction of certain conditions and payment of an extension fee. In addition, an accordion feature allows the facility to be increased to up to $600.0 million , subject to obtaining additional lender commitments. During the fourth quarter of 2015, upon obtaining additional lender commitments, the Company increased the term facility from $325.0 million to $370.0 million . Borrowings may be repaid without premium or penalty, and may be reborrowed within 30 days up to the then available loan commitment. Borrowings bear interest at either a specified base rate or LIBOR plus a margin, at the Operating Partnership’s option. As of March 31, 2016 , the Term Loan bore interest at LIBOR plus 1.60% . Initially, borrowings under the Term Loan bear interest at either LIBOR plus 1.35% to 1.80% per annum or a specified base rate plus 0.35% to 0.80% per annum. Initially, the applicable margin is determined based upon the Corporation’s leverage ratio. If the Corporation obtains at least two credit ratings on its senior unsecured long-term indebtedness of BBB- from S&P or Fitch, Inc. or Baa3 from Moody's, the Operating Partnership may make an irrevocable election to have the margin based upon the Corporation's credit ratings, in which case borrowings under the Term Loan will bear interest at either LIBOR plus 0.90% to 1.75% per annum or a specified base rate plus 0.0% to 0.75% per annum, in each case depending on the Corporation’s credit ratings. The Operating Partnership may voluntarily prepay the Term Loan, in whole or in part, at any time, without premium or penalty, but subject to applicable LIBOR breakage fees. Payment of the Term Loan is unconditionally guaranteed by the Corporation and, under certain circumstances, by one or more material subsidiaries (as defined in the Term Loan Agreement) of the Corporation. The obligations of the Corporation and any guarantor under the Term Loan are full recourse to the Corporation and each guarantor. As a result of entering into the Term Loan, the Company incurred origination costs of $2.3 million . These deferred financing costs are being amortized to interest expense over the remaining initial term of the Term Loan. As of March 31, 2016 and December 31, 2015 , the unamortized deferred financing costs relating to the Term Loan were $2.0 million and $2.1 million , respectively, and recorded net against the principal balance of the Term Loan on the accompanying consolidated balance sheets. As of March 31, 2016 , $334.0 million of borrowings were outstanding and $36.0 million of borrowing capacity was available under the Term Loan. The Operating Partnership's ability to borrow under the Term Loan is subject to ongoing compliance with a number of customary financial covenants and other customary affirmative and negative covenants. The Corporation has unconditionally guaranteed all obligations of the Operating Partnership under the Term Loan Agreement. As of March 31, 2016 , the Corporation and the Operating Partnership were in compliance with these financial covenants. Master Trust Notes The Company has access to an asset-backed securitization platform, the Spirit Master Funding Program, to raise capital through the issuance of non-recourse net-lease mortgage notes collateralized by commercial real estate, net-leases and mortgage loans. The Spirit Master Funding Program consists of two separate securitization trusts, Master Trust 2013 and Master Trust 2014, each of which have one or multiple bankruptcy-remote, special purpose entities as issuers or co-issuers of the notes. Each issuer is an indirect wholly-owned special purpose entity of the Corporation. The Master Trust Notes are summarized below: Stated Rates (1) Maturity March 31, December 31, (in Years) (in Thousands) Series 2014-1 Class A1 5.1 % 4.2 $ 62,312 $ 65,027 Series 2014-1 Class A2 5.4 % 4.3 253,300 253,300 Series 2014-2 5.8 % 5.0 228,845 229,674 Series 2014-3 5.7 % 6.0 312,164 312,276 Series 2014-4 Class A1 3.5 % 3.8 150,000 150,000 Series 2014-4 Class A2 4.6 % 13.8 360,000 360,000 Total Master Trust 2014 notes 5.1 % 7.2 1,366,621 1,370,277 Series 2013-1 Class A 3.9 % 2.7 125,000 125,000 Series 2013-2 Class A 5.3 % 7.7 195,732 196,817 Total Master Trust 2013 notes 4.7 % 5.8 320,732 321,817 Total Master Trust Notes 1,687,353 1,692,094 Debt discount, net (21,890 ) (22,909 ) Deferred financing costs, net (18,644 ) (19,345 ) Total Master Trust Notes, net $ 1,646,819 $ 1,649,840 (1) Represents the individual series stated interest rate as of March 31, 2016 and the weighted average stated rate of the total Master Trust Notes, based on the collective series outstanding principal balances as of March 31, 2016 . As of March 31, 2016 , the Master Trust 2014 notes were secured by 929 owned and financed properties issued by five indirect wholly-owned subsidiaries of the Corporation. The notes issued under Master Trust 2014 are cross-collateralized by the assets of all issuers within this trust. As of March 31, 2016 , the Master Trust 2013 notes were secured by 307 owned and financed properties issued by a single indirect wholly-owned subsidiary of the Corporation. CMBS As of March 31, 2016 , indirect wholly-owned special purpose entity subsidiaries of the Corporation were borrowers under 133 fixed and 8 variable-rate non-recourse loans, excluding the defaulted loans, which have been securitized into CMBS and are secured by the borrowers' respective leased properties and related assets. The stated interest rates as of March 31, 2016 for the fixed-rate notes, excluding the defaulted loans, ranged from 3.90% to 6.62% with a weighted average stated interest rate of 5.81% , and the weighted average stated interest rate for the variable-rate notes was 3.84% . As of March 31, 2016 , these fixed and variable-rate loans were secured by 377 and 83 properties, respectively. The Company entered into interest rate swaps that effectively fixed the interest rates at approximately 5.14% on the variable-rate loans (see Note 5). As of March 31, 2016 and December 31, 2015 , the unamortized deferred financing costs associated with the CMBS loans were $5.3 million and $5.5 million , respectively, and recorded net against the principal balance of the mortgages and notes payable on the accompanying consolidated balance sheets. The deferred financing costs are being amortized to interest expense over the term of the respective loans. As of March 31, 2016 , certain borrowers were in default under the loan agreements relating to four separate CMBS fixed-rate loans where the eight properties securing the respective loans were no longer generating sufficient revenue to pay the scheduled debt service. The default interest rate on these loans was between 9.67% and 10.88% . Each defaulted borrower is a bankruptcy remote special purpose entity and the sole owner of the collateral securing the loan obligations. As of March 31, 2016 , the aggregate principal balance under the defaulted CMBS loans was $69.1 million , which includes $9.5 million of interest added to principal. In addition, approximately $12.5 million of lender controlled restricted cash is being held in connection with these loans that may be applied to reduce amounts owed. Convertible Notes In May 2014, the Corporation issued $402.5 million aggregate principal amount of 2.875% convertible notes due in 2019 and $345.0 million aggregate principal amount of 3.75% convertible notes due in 2021. Interest on the Convertible Notes is payable semiannually in arrears on May 15 and November 15 of each year. The 2019 Notes will mature on May 15, 2019 and the 2021 Notes will mature on May 15, 2021 . The Convertible Notes are convertible only during certain periods and, subject to certain circumstances, into cash, shares of the Corporation's common stock, or a combination thereof. The initial conversion rate applicable to each series is 76.3636 per $1,000 principal note (equivalent to an initial conversion price of $13.10 per share of common stock, representing a 22.5% premium above the public offering price of the common stock offered concurrently at the time the Convertible Notes were issued). Earlier conversion may be triggered if shares of the Corporation's common stock trades higher than the established thresholds, if the Convertible Notes trade below established thresholds, or certain corporate events occur. In connection with the issuance of the Convertible Notes, the Company recorded a discount of $56.7 million , which represents the estimated value of the embedded conversion feature for each of the Convertible Notes. The discount is being amortized to interest expense using the effective interest method over the term of each of the 2019 Notes and 2021 Notes. As of March 31, 2016 and December 31, 2015 , the unamortized discount was $40.5 million and $42.7 million , respectively. The discount is shown net against the aggregate outstanding principal balance of the Convertible Notes on the accompanying consolidated balance sheets. The equity component of the conversion feature is recorded in capital in excess of par value in the accompanying consolidated balance sheets, net of financing transaction costs. In connection with the offering, the Company also incurred $19.6 million in deferred financing costs. This amount has been allocated on a pro-rata basis to each of the Convertible Notes and is being amortized to interest expense over the term of each note. As of March 31, 2016 and December 31, 2015 , the unamortized deferred financing costs relating to the Convertible Notes were $13.9 million and $14.7 million , respectively, and recorded net against the Convertible Notes principal balance on the accompanying consolidated balance sheets. Debt Extinguishment During the three months ended March 31, 2016 , the Company extinguished a total of $103.8 million aggregate principal amount of senior mortgage indebtedness with a weighted average contractual interest rate of 6.72% . As a result of these transactions, the Company recognized a net loss on debt extinguishment of approximately $5.3 million . During the three months ended March 31, 2015 , the Company extinguished a total of $162.8 million aggregate principal amount of senior mortgage indebtedness with a weighted average contractual interest rate of 5.76% and terminated the 2013 Credit Facility. As a result of these transactions, the Company recognized a net loss on debt extinguishment of approximately $1.2 million .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative and Hedging Activities	Derivative and Hedging Activities The Company uses interest rate derivative contracts to manage its exposure to changes in interest rates on its variable rate debt. These derivatives are considered cash flow hedges and are recorded on a gross basis at fair value. Assessments of hedge effectiveness are performed quarterly using regression analysis and the measurement of hedge ineffectiveness is based on the hypothetical derivative method. The effective portion of changes in fair value are recorded in AOCL and subsequently reclassified to earnings when the hedged transactions affect earnings. The ineffective portion is recorded immediately in earnings in general and administrative expenses. The Company is exposed to credit risk in the event of non-performance by its derivative counterparties. The Company evaluates counterparty credit risk through monitoring the creditworthiness of counterparties, which includes review of debt ratings and financial performance. To mitigate its credit risk, the Company enters into agreements with counterparties it considers credit-worthy, such as large financial institutions with favorable credit ratings. As of March 31, 2016 and December 31, 2015 , there were no termination events or events of default related to the interest rate swaps. The following table summarizes the notional amount and fair value of the Company’s derivative instruments (dollars in thousands): Fair Value of Liability Derivatives Designated as Hedging Instruments Balance Sheet Location Notional Fixed Interest Effective Maturity March 31, December 31, Interest Rate Swaps (1) Accounts payable, accrued expenses and other liabilities $ 61,758 5.14 % 01/02/14 12/13/18 $ (1,585 ) $ (934 ) $ (1,585 ) $ (934 ) (1) Represents a tranche of eight individual interest rate swap agreements with notional amounts ranging from $7.6 million to $7.9 million . The payment terms, stated interest rate, effective date, and maturity date of these swaps are consistent with the terms of the debt. The following tables provide information about the amounts recorded in AOCL, as well as the loss recorded in operations, when reclassified out of AOCL or recognized in earnings immediately, for the three months ended March 31, 2016 and 2015 , respectively (in thousands): Amount of Loss Recognized in AOCL on Derivative (Effective Portion) Three Months Ended Derivatives in Cash Flow Hedging Relationships 2016 2015 Interest rate swaps $ (856 ) $ (852 ) Amount of Loss Reclassified from AOCL into Operations (Effective Portion) Three Months Ended Location of Loss Reclassified from AOCL into Operations 2016 2015 Interest expense $ (235 ) $ (317 ) Amount of Loss Recognized in Operations on Derivative (Ineffective Portion) Three Months Ended Location of Loss Recognized in Operations on Derivatives 2016 2015 General and administrative expense $ — $ (4 ) Approximately $0.8 million of the remaining balance in AOCL is estimated to be reclassified as an increase to interest expense during the next twelve months.

The net proceeds were used to fund acquisitions, repay borrowings under the Revolving Credit Facilities and for general corporate purposes. As of March 31, 2016 , $89.3 million in gross proceeds capacity remained available under the ATM Program. Stock Repurchase Program In February 2016, the Company's Board of Directors approved a stock repurchase program, which authorizes the Company to purchase up to $200.0 million of its common stock in the open market or through private transactions from time to time over the next 18 months. The stock repurchase program does not obligate the Company to repurchase any specific number of shares and may be suspended at any time at the Company's discretion. The Company intends to fund any repurchases with the net proceeds from asset sales, cash flows from operations, existing cash on the balance sheet and other sources. During the three months ended March 31, 2016 , no stock was repurchased under the stock repurchase program. Repurchase of Shares of Common Stock During the three months ended March 31, 2016 , portions of awards of restricted common stock and performance share awards granted to certain of the Company's officers and other employees vested. The vesting of these awards, granted pursuant to the Incentive Award Plan, resulted in federal and state income tax liabilities for the recipients. As permitted by the terms of the Incentive Award Plan and the award grants, certain executive officers and employees elected to surrender 0.1 million shares of common stock valued at $0.7 million , solely to pay the associated minimum statutory tax withholdings during the three months ended March 31, 2016 . The Company records its repurchased shares of common stock using the cost method. Shares repurchased are considered retired under Maryland law and the cost of the stock repurchased is recorded as a reduction to common stock and accumulated deficit on the consolidated balance sheets.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company is periodically subject to claims or litigation in the ordinary course of business, including claims generated from business conducted by tenants on real estate owned by the Company. In these instances, the Company is typically indemnified by the tenant against any losses that might be suffered, and the Company and/or the tenant are typically insured against such claims. On September 8, 2015, Haggen Holdings, LLC and a number of its affiliates, including Haggen Operations Holdings, LLC, (collectively, the "Debtors") filed petitions for bankruptcy protection under Chapter 11 of the U.S. Bankruptcy Code in the U.S. Bankruptcy Court for the District of Delaware. At the time of the filing, Haggen Operations Holdings, LLC leased 20 properties on a triple net basis from a subsidiary of the Company under a master lease with initial monthly rents of $1.4 million and an initial lease expiration date of February 28, 2035. Haggen Holdings, LLC is the guarantor of the tenant’s obligations under that master lease. A subsidiary of the Company and the debtors entered into a settlement agreement whereby the subsidiary consented to the partial assumption and partial rejection of the master lease permitting (a) the assumption of nine stores subject to the lease and their assignment to three unaffiliated grocery operators with winning bids in an auction of the respective leaseholds, (b) the rejection of the leasehold with respect to six of the stores and their return to the Company's possession, and (c) the assumption and continued operation by the tenant of five of the stores. Under the settlement agreement, the subsidiary of the Company received an unsecured stipulated damages claim for $21.0 million against each of Haggen Operations Holdings, LLC and Haggen Holdings, LLC, as well as certain agreed upon fees, expenses and cure payments in the bankruptcy. The court approved the settlement agreement in an order entered November 25, 2015. The bankruptcy proceeding remains ongoing, and there is no guaranty that the claims will be paid or otherwise satisfied in full. As of March 31, 2016 , there were no outstanding claims against the Company that are expected to have a material adverse effect on the Company’s financial position, results of operations or cash flows. As of March 31, 2016 , the Company had commitments totaling $30.1 million , of which $3.0 million relates to future acquisitions with the remainder to fund improvements on properties the Company currently owns. Commitments related to acquisitions contain standard cancellation clauses contingent on the results of due diligence. Of the $30.1 million of total commitments, $29.8 million is expected to be funded during fiscal year 2016 . In addition, the Company is contingently liable for $5.7 million of debt owed by one of its tenants and is indemnified by that tenant for any payments the Company may be required to make on such debt. The Company estimates future costs for known environmental remediation requirements when it is probable that the Company has incurred a liability and the related costs can be reasonably estimated. The Company considers various factors when estimating its environmental liabilities, and adjustments are made when additional information becomes available that affects the estimated costs to study or remediate any environmental issues. When only a wide range of estimated amounts can be reasonably established and no other amount within the range is better than another, the low end of the range is recorded in the consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Recurring Fair Value Measurements The Company’s assets and liabilities that are required to be measured at fair value in the accompanying consolidated financial statements are summarized below. The following table sets forth the Company’s financial liabilities that were accounted for at fair value on a recurring basis (in thousands): Fair Value Hierarchy Level Fair Value Level 1 Level 2 Level 3 March 31, 2016 Derivatives: Interest rate swaps financial liabilities $ (1,585 ) $ — $ (1,585 ) $ — December 31, 2015 Derivatives: Interest rate swaps financial liabilities $ (934 ) $ — $ (934 ) $ — The interest rate swaps are measured using a market approach, using prices obtained from a nationally recognized pricing service and pricing models with market observable inputs such as interest rates and volatilities. These measurements are classified as Level 2 of the fair value hierarchy. Nonrecurring Fair Value Measurements Fair value measurement of an asset on a nonrecurring basis occurs when events or changes in circumstances related to an asset indicate that the carrying amount of the asset is no longer recoverable. The following table sets forth the Company’s assets that were accounted for at fair value on a nonrecurring basis (in thousands): Fair Value Hierarchy Level Impairment Charges (1) Description Fair Value Dispositions Level 1 Level 2 Level 3 March 31, 2016 Long-lived assets held and used $ 6,329 $ — $ — $ — $ 6,329 $ (7,235 ) Lease intangible assets 1,723 — — — 1,723 (1,267 ) Other assets — — — — — 324 Long-lived assets held for sale 21,874 — — — 21,874 (3,953 ) $ (12,131 ) December 31, 2015 Long-lived assets held and used $ 60,298 $ (3,207 ) $ — $ — $ 63,505 $ (51,002 ) Lease intangible assets 3,843 — — — 3,843 (3,825 ) Other assets — — — — — (324 ) Long-lived assets held for sale 15,957 (33,563 ) — — 49,520 (14,617 ) $ (69,768 ) (1) Impairment charges are presented for the three months ended March 31, 2016 and for the year ended December 31, 2015 . The fair values of impaired real estate and intangible assets were determined by using the following information, depending on availability, in order of preference: signed purchase and sale agreements or letters of intent; recently quoted bid or ask prices, or market prices for comparable properties; estimates of cash flow, which consider, among other things, contractual and forecasted rental revenues, leasing assumptions, and expenses based upon market conditions; and expectations for the use of the real estate. Based on these inputs, the Company determined that its valuation of the impaired real estate and intangible assets falls within Level 3 of the fair value hierarchy. Estimated Fair Value of Financial Instruments Financial assets and liabilities for which the carrying values approximate their fair values include cash and cash equivalents, restricted cash and escrow deposits, and accounts receivable and payable. Generally, these assets and liabilities are short-term in duration and are recorded at cost, which approximates fair value, on the accompanying consolidated balance sheets. In addition to the disclosures for assets and liabilities required to be measured at fair value at the balance sheet date, companies are required to disclose the estimated fair values of all financial instruments, even if they are not carried at their fair values. The fair values of financial instruments are estimates based upon market conditions and perceived risks at March 31, 2016 and December 31, 2015 . These estimates require management’s judgment and may not be indicative of the future fair values of the assets and liabilities. The estimated fair values of the loans receivable, Revolving Credit Facilities, Term Loan, Convertible Notes and the fixed-rate mortgages and notes payable have been derived based on market quotes for comparable instruments or discounted cash flow analyses using estimates of the amount and timing of future cash flows, market rates and credit spreads. The loans receivable, Revolving Credit Facilities, Term Loan, Convertible Notes and mortgages and notes payable were measured using a market approach from nationally recognized financial institutions with market observable inputs such as interest rates and credit analytics. These measurements are classified as Level 2 of the fair value hierarchy. The following table discloses fair value information for these financial instruments (in thousands): March 31, 2016 December 31, 2015 Carrying Value Estimated Fair Value Carrying Value Estimated Fair Value Loans receivable, net $ 101,602 $ 107,284 $ 104,003 $ 110,019 Revolving Credit Facilities 24,000 24,430 — — Term Loan, net (1) 332,019 334,206 322,902 338,366 Mortgages and notes payable, net (1) 2,969,893 3,151,982 3,079,787 3,220,239 Convertible Notes, net (1) 693,173 751,519 690,098 713,095 (1) The carrying value of the debt instruments are net of unamortized deferred financing costs and certain debt discounts/premiums.

Incentive Award Plan	Incentive Award Plan As of March 31, 2016 , 0.8 million shares remained available for award under the Incentive Award Plan. On March 30, 2016, the Company's Board of Directors adopted, subject to stockholder approval, an amendment and restatement of the Incentive Award Plan, which would increase the number of shares of common stock reserved for issuance thereunder by 5,500,000 shares. Restricted Shares of Common Stock During the three months ended March 31, 2016 , the Company granted 0.4 million restricted shares under the Incentive Award Plan to certain executive officers and employees. The Company recorded $3.8 million in deferred compensation associated with these grants, which will be recognized in expense over the service period of the awards. As of March 31, 2016 , there were approximately 0.8 million unvested restricted shares outstanding. Performance Share Awards During the three months ended March 31, 2016 , the Board of Directors or committee thereof approved an initial target grant of 310,706 performance shares to executive officers of the Company. The performance period of this grant runs from January 1, 2016 through December 31, 2018. Potential shares of the Corporation's common stock that each participant is eligible to receive is based on the initial target number of shares granted multiplied by a percentage range between 0% and 250% . Grant date fair value was calculated using the Monte Carlo simulation model, which incorporated stock price correlation, projected dividend yields and other variables over the time horizons matching the performance periods. Stock-based compensation expense associated with unvested performance share awards is recognized on a straight-line basis over the minimum required service period, which is generally three years. Based on the grant date fair value, the Corporation expects to recognize $5.0 million in compensation expense on a straight-line basis over the requisite service period associated with this market-based grant. Approximately $0.3 million and $0.2 million in dividend rights have been accrued for non-vested performance share awards outstanding as of March 31, 2016 and December 31, 2015 , respectively. For outstanding non-vested awards at March 31, 2016 , 0.6 million shares would have been released based on the Corporation's TSR relative to the specified peer groups through that date. During the three months ended March 31, 2016 , 53,533 shares were released at target in connection with qualifying terminations of participants. Stock-based Compensation Expense For the three months ended March 31, 2016 and 2015 , the Company recognized $2.3 million and $3.8 million , respectively, in stock-based compensation expense, which is included in general and administrative expenses in the accompanying consolidated statements of operations. As of March 31, 2016 , the remaining unamortized stock-based compensation expense, including amounts relating to the performance share awards, totaled $15.2 million , including $7.4 million related to restricted stock awards and $7.8 million related to performance share awards, which is recognized as the greater of the amount amortized on a straight-line basis over the service period of each applicable award or the amount vested over the vesting periods.

Earnings Per Share [Abstract]
Income Per Share	Income Per Share Income per share has been computed using the two-class method. Income per common share under the two-class method is computed by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted average number of shares of common stock outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both shares of common stock and participating securities based on the weighted average shares outstanding during the period. Classification of the Company's unvested restricted stock, which contain rights to receive nonforfeitable dividends, are deemed participating securities under the two-class method. Under the two-class method, earnings attributable to unvested restricted shares are deducted from income from continuing operations in the computation of net income attributable to common stockholders. The table below is a reconciliation of the numerator and denominator used in the computation of basic and diluted net income per share computed using the two-class method (dollars in thousands): Three Months Ended 2016 2015 Basic and diluted income: Income from continuing operations $ 13,441 $ 13,761 Gain on disposition of assets 12,562 11,336 Less: income attributable to unvested restricted stock (127 ) (209 ) Income used in basic and diluted income per share from continuing operations 25,876 24,888 Income from discontinued operations — 227 Net income attributable to common stockholders used in basic and diluted income per share $ 25,876 $ 25,115 Basic weighted average shares of common stock outstanding: Weighted average shares of common stock outstanding 442,033,226 412,195,685 Less: unvested weighted average shares of restricted stock (667,299 ) (1,177,790 ) Weighted average shares of common stock outstanding used in basic income per share 441,365,927 411,017,895 Net income per share attributable to common stockholders—basic $ 0.06 $ 0.06 Diluted weighted average shares of common stock outstanding: (1) Unvested performance shares — 598,015 Stock options 2,480 6,524 Weighted average shares of common stock outstanding used in diluted income per share 441,368,407 411,622,434 Net income per share attributable to common stockholders—diluted $ 0.06 $ 0.06 Potentially dilutive shares of common stock Unvested shares of restricted stock 67,709 457,283 Total 67,709 457,283 (1) Assumes the most dilutive issuance of potentially issuable shares between the two-class and treasury stock method unless the result would be anti-dilutive. The Corporation intends to satisfy its exchange obligation for the principal amount of the Convertible Notes to the note holders entirely in cash, therefore, the "if-converted" method does not apply and the treasury stock method is being used. As the Corporation's stock price is below the conversion price, there are no potentially dilutive shares associated with the Convertible Notes.

Accounting Policies [Abstract]
Basis of Accounting	Basis of Accounting and Principles of Consolidation The accompanying unaudited consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the SEC. In the opinion of management, the unaudited consolidated financial statements include the normal, recurring adjustments necessary for a fair statement of the information required to be set forth therein. The results for interim periods are not necessarily indicative of the results for the entire year. Certain information and note disclosures, normally included in financial statements prepared in accordance with GAAP, have been condensed or omitted from these statements pursuant to SEC rules and regulations and, accordingly, these financial statements should be read in conjunction with the Company’s audited consolidated financial statements as filed with the SEC in its Annual Report on Form 10-K for the year ended December 31, 2015 .
Consolidation	The unaudited consolidated financial statements include the accounts of the Corporation and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Special Purpose Entities	The Company has formed numerous special purpose entities to acquire and hold real estate encumbered by indebtedness (see Note 4). As a result, the majority of the Company’s consolidated assets are held in these wholly-owned special purpose entities. Each special purpose entity is a separate legal entity and is the sole owner of its assets and responsible for its liabilities. The assets of these special purpose entities are not available to pay, or otherwise satisfy obligations to, the creditors of any affiliate or owner of another entity unless the special purpose entities have expressly agreed and are permitted under their governing documents.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Although management believes its estimates are reasonable, actual results could differ from those estimates.
Segment Reporting	Segment Reporting The Company views its operations as one segment, which consists of net leasing operations. The Company has no other reportable segments.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The Company provided for reserves for uncollectible amounts related to its rent and other tenant receivables totaling $11.8 million and $11.5 million at March 31, 2016 and December 31, 2015 , respectively, against accounts receivable balances of $26.9 million and $26.3 million , respectively. Receivables are recorded within deferred costs and other assets, net in the accompanying consolidated balance sheets. The Company established a reserve for losses of $9.9 million and $12.2 million at March 31, 2016 and December 31, 2015 , respectively, against deferred rental revenue receivables of $70.8 million and $68.0 million , respectively. Deferred rental revenue receivables are recorded within deferred costs and other assets, net in the accompanying consolidated balance sheets.
Income Taxes	Income Taxes The Company has elected to be taxed as a REIT under the Code. As a REIT, the Company generally will not be subject to federal income tax provided it continues to satisfy certain tests concerning the Company’s sources of income, the nature of its assets, the amounts distributed to its stockholders, and the ownership of Company stock. Management believes the Company has qualified and will continue to qualify as a REIT and therefore, no provision has been made for federal income taxes in the accompanying consolidated financial statements. Even if the Company qualifies for taxation as a REIT, it may be subject to state and local income and franchise taxes, and to federal income tax and excise tax on its undistributed income. Franchise taxes are included in general and administrative expenses on the accompanying consolidated statements of operations. Taxable income from non-REIT activities managed through the Company’s taxable REIT subsidiaries are subject to federal, state, and local taxes, which are not material.
Reclassifications	Reclassifications Certain reclassifications have been made to prior period balances to conform to the current period presentation.
New Accounting Pronouncements	New Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB or the SEC that are adopted by the Company as of the specified effective date. Unless otherwise discussed, these new accounting pronouncements entail technical corrections to existing guidance or affect guidance related to specialized industries or entities and therefore will have minimal, if any, impact on the Company's financial position or results of operations upon adoption. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which supersedes the existing guidance for lease accounting, Leases (Topic 840) . ASU 2016-02 requires lessees to recognize leases on their balance sheets, and leaves lessor accounting largely unchanged. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early application is permitted for all entities. ASU 2016-02 requires a modified retrospective approach for all leases existing at, or entered into after, the date of initial application, with an option to elect to use certain transition relief. The Company is currently evaluating the impact of this ASU on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting , which simplifies many aspects of accounting for share-based payment transactions under ASC Topic 718, Compensation - Stock Compensation , including income tax consequences, classification of awards as either equity or liability, forfeiture rate calculations and classification on the statement of cash flows. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted for all entities. The Company is currently evaluating the impact of this ASU on its consolidated financial statements.
