Gladstone Commercial Corporation
Notes to Condensed Consolidated Financial Statements (Unaudited)

1. Organization, Basis of Presentation and Significant Accounting Policies

Gladstone Commercial Corporation is a real estate investment trust (“REIT”) that was incorporated under the General Corporation Law of the State of Maryland on February 14, 2003. We focus on acquiring, owning and managing primarily office and industrial properties. On a selective basis, we may make long term industrial and commercial mortgage loans; however, we do not have any mortgage loans currently outstanding. Subject to certain restrictions and limitations, our business is managed by Gladstone Management Corporation, a Delaware corporation ("Adviser"(the "Adviser"), and administrative services are provided by Gladstone Administration, LLC, a Delaware limited liability company ("Administrator"(the "Administrator"), each pursuant to a contractual arrangement with us. Our Adviser and Administrator collectively employ all of our personnel and pay their salaries, benefits, and general expenses directly. Gladstone Commercial Corporation conducts substantially all of its operations through a subsidiary, Gladstone Commercial Limited Partnership, a Delaware limited partnership or the Operating Partnership.(the "Operating Partnership").

All further references herein to “we,” “our,” “us” and “us”the "Company" mean Gladstone Commercial Corporation and its consolidated subsidiaries, except where it is made clear that the term means only Gladstone Commercial Corporation.

Interim Financial Information

Our interim financial statements are prepared in accordance with generally accepted accounting principles ("GAAP") for interim financial information and pursuant to the requirements for reporting on Form 10-Q and in accordance with Article 10 of Regulation S-X. Accordingly, certain disclosures accompanying annual financial statements prepared in accordance with GAAP are omitted. The year-end balance sheet data presented herein was derived from audited financial statements, but does not include all disclosures required by GAAP. In the opinion of our management, all adjustments, consisting solely of normal recurring accruals, necessary for the fair statement of financial statements for the interim period, have been included. The interim financial statements and notes thereto should be read in conjunction with the financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016,2017, as filed with the U.S. Securities and Exchange Commission on February 15, 2017.14, 2018. The results of operations for the three and nine months ended September 30, 2017March 31, 2018 are not necessarily indicative of the results that may be expected for other interim periods or for the full fiscal year.

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 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 periods. Actual results could materially differ from those estimates.

Critical Accounting Policies

In preparation of our financial statements in accordance with GAAP, we apply certain critical accounting policies which require management to make judgments that are subjective in nature to make certain estimates and assumptions. Application of our accounting policies involves the exercise of judgment regarding the use of assumptions as to future uncertainties, and as a result, actual results could materially differ from these estimates. A summary of all of our significant accounting policies is provided in Note 1 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016.2017. There were no material changes to our critical accounting policies during the three and nine months ended September 30, 2017.

Reclassifications

Certain items on condensed consolidated statement of operations and other comprehensive income (loss) for the three and nine months ended September 30, 2016 have been reclassified to conform to the current period's presentation. These reclassifications had no impact on previously-reported equity, net loss attributable to common stockholders, or net change in cash and cash equivalents.March 31, 2018.


Recently Issued Accounting Pronouncements

In May 2014, the FASBFinancial Accounting Standards Board ("FASB") issued guidance regarding the recognition of revenue from contracts with customers. Under this guidance, an entity will recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance also requires improved disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. We adopted this guidance for our annual and interim periods beginning January 1, 2018 and will use the modified retrospective method, under which the cumulative effect of initially applying the guidance is recognized at the date of initial application. Our adoption of this guidance did not have a material impact on our consolidated financial statements. Further, as discussed below, once the new guidance regarding the principles for the recognition measurement, presentation and disclosure of leases goes into effect on January 1, 2019, we expect the new revenue standard will apply to executory costs and other components of revenue due under leases that are deemed to be non-lease components (examples include common area maintenance and provision of utilities), even when the revenue for such activities is not separately stipulated in the lease. Revenue from these non-lease components, which were previously recognized on a straight-line basis under current lease guidance, would be recognized under the new revenue guidance as the related services are delivered. As a result, while theour total revenue recognized over the lease term would not differ under the new guidance, the revenue recognition pattern could be different. We are in the process ofcurrently evaluating the significanceimpact of revenue recognition from the adoption of the difference in the revenue recognition pattern that would result from this change, and adjustments in revenue recognition attributable to non-lease components will take effect in tandem with the new leasinglease standard described below, which is effective January 1, 2019. We will adopt this guidance foron our annual and interim periods beginning January 1, 2018 and expect to use the modified retrospective method, under which the cumulative effect of initially applying the guidance is recognized at the date of initial application.consolidated financial statements.

In February 2016, the FASB issued ASUAccounting Standards Update ("ASU") 2016-02, “Leases: Amendments to the FASB Accounting Standards Codification” (“ASU 2016-02”). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. We are evaluating the adoption of ASU 2016-02, is expectedbut we expect the standard to minimally impact our consolidated financial statements as we currently have four operating ground lease arrangements with terms greater than one year for which we are the lessee, and we don't expect the purchase of properties with ground leases to be crucial to our acquisition strategy. We also expect our general and administrative expense to increase as the new standard requires us to expense indirectnon-incremental leasing costs that were previously capitalized to leasing commissions. ASCASU 2016-02 supersedes the previous leases standard, ASC 840 "Leases." The standard is effective on January 1, 2019, with early adoption permitted and we expect to usepermitted. We will adopt using the modified retrospective method, under which the cumulative effect of initially applying the guidance is recognized at the date of initial application.

In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging issuesIssues Task Force)," which clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows with the objective of reducing the existing diversity in practice related to eight specific cash flow issues. The areas addressed in the new guidance relate to debt prepayment costs, settlement of zero-coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned and bank-owned life insurance policies, distributions received from equity method investments, beneficial interest in securitization transactions and separately identifiable cash flows and application of the predominance principle.

The adoption of this guidance todid not have a material impact on our consolidated financial statements.statements, as we have not historically completed transactions contemplated in this update.

In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)," which requires the statement of cash flows to explain the change during the period in the total of cash, cash equivalents and amounts described as restricted cash or restricted cash equivalents. Under the new guidance, amounts described as restricted cash and restricted cash equivalents will be included with cash and cash equivalents when reconciling the beginning of period and end of periodsperiod total amounts shown on the statement of cash flows. TheWe adopted this guidance is effective for usthe calendar year beginning January 1, 2018, with early adoption permitted.and the standard requires retrospective adoption. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.


In AugustFebruary 2017, the FASB issued ASU 2017-12, "Targeted Improvements2017-05 to Accountingprovide guidance for Hedging Activities" ("ASU 2017-12").recognizing gains and losses from the transfer of nonfinancial assets and in-substance non-financial assets in contracts with non-customers, unless other specific guidance applies. The new standard simplifiesrequires a company to de-recognize nonfinancial assets once it transfers control of a distinct nonfinancial asset or distinct in substance nonfinancial asset. Additionally, when a company transfers its controlling interest in a nonfinancial asset, but retains a noncontrolling ownership interest, the applicationcompany is required to measure any non-controlling interest it receives or retains at fair value. The guidance requires companies to recognize a full gain or loss on the transaction. As a result of hedge accounting and better aligns financial reporting for hedging activities with companies' economic objectives in undertaking those activities. Under the new guidance, all changesthe guidance specific to real estate sales in the fair value of highly effective cash flow hedgesASC 360-20 will be recorded ineliminated, and partial sales of real estate assets will now be subject to the same de-recognition model as all other comprehensive income instead of income.

2. Related-Party Transactions

Gladstone Management and Gladstone Administration

We are externally managed pursuant to contractual arrangements with our Adviser and our Administrator, which collectively employ all of our personnel and pay their salaries, benefits, and general expenses directly. Both our Adviser and Administrator are affiliates of ours, as their parent company is owned and controlled by Mr. David Gladstone, our chairman and chief executive officer. Two of our executive officers, Mr. Gladstone and Mr. Terry Brubaker (our vice chairman and chief operating officer) serve as directors and executive officers of our Adviser and our Administrator. Our president, Mr. Robert Cutlip, is an executive managing director of our Adviser. Mr. Michael LiCalsi, our general counsel and secretary, serves as our Administrator’s president, general counsel and secretary. We have entered into an advisory agreement with our Adviser, as amended from time to time or the Advisory Agreement,(the "Advisory Agreement"), and an administration agreement with our Administrator or the Administration Agreement.(the "Administration Agreement"). The services and fees under the Advisory Agreement and Administration Agreement are described below. As of September 30, 2017March 31, 2018 and December 31, 2016, $2.32017, $2.4 million and $2.1$2.3 million, respectively, were collectively due to our Adviser and Administrator.

Base Management Fee

On July 24, 2015,January 10, 2017, we entered into a Second Amended and Restated Advisory Agreement with the Adviser, effective July 1, 2015. We subsequently entered into a Third Amended and Restated Advisory Agreement with the Adviser on July 12, 2016, effective July 1, 2016, and, as described below, a Fourth Amended and Restated Investment Advisory Agreement with the Adviser, on January 10, 2017, effective as of October 1, 2016. Our entrance into the Advisory Agreement and each subsequent amendment thereof (including the fourth amendment completed in January of the amended Advisory Agreements2017) was approved unanimously by our Board of Directors. Our Board of Directors also reviews and considers renewing the agreement with our AdviserAdvisory Agreement each July. As such, during theDuring its July 2017 meeting, theour Board of Directors reviewed and renewed the Advisory Agreement for anotheran additional year, through August 31, 2018.

As a result ofUnder the July 2015 amendment,Advisory Agreement, the calculation of the annual base management fee equals 1.5% of our adjusted total stockholders’ equity, which is our total stockholders’ equity plus total mezzanine equity (before giving effect to the base management fee and incentive fee), adjusted to exclude the effect of any unrealized gains or losses that do not affect realized net income (including impairment charges) and adjusted for any one-time events and certain non-cash items (the later to occur for a given quarter only upon the approval of our Compensation Committee). The fee is calculated and accrued quarterly as 0.375% per quarter of such adjusted total stockholders’ equity figure. As a result of the July 2016 amendment, the definition of adjusted total stockholders' equity in the calculation of the base management fee and the incentive fee (described below) includes total mezzanine equity. Our Adviser does not charge acquisition or disposition fees when we acquire or dispose of properties, as is common in other externally managed REITs; however, our Adviser may earn fee income from our borrowers, tenants or other sources. Prior to the 2015 amendment, the Advisory Agreement provided for an annual base management fee equal to 2.0% of our common stockholders’ equity, which was our total stockholders’ equity, less the recorded value of any preferred stock and adjusted to exclude the effect of any unrealized gains, losses, or other items that did not affect realized net income (including impairment charges).

For the three and nine months ended September 30,March 31, 2018 and 2017, we recorded a base management fee of $1.3 million and $3.7 million, respectively. For the three and nine months ended September 30, 2016, we recorded a base management fee of $1.1 million and $2.8$1.2 million, respectively.

Incentive Fee

As a result ofPursuant to the July 2015 amendment,Advisory Agreement, the calculation of the incentive fee was revised to rewardrewards the Adviser in circumstances where our quarterly Core FFO (defined at the end of this paragraph), before giving effect to any incentive fee, or pre-incentive fee Core FFO, exceeds 2.0% quarterly, or 8.0% annualized, of adjusted total stockholders’ equity (after giving effect to the base management fee but before giving effect to the incentive fee, and which, as a result of the July 2016 amendment to the Advisory Agreement, now includes total mezzanine equity)fee). We refer to this as the new hurdle rate. The Adviser will receive 15.0% of the amount of our pre-incentive fee Core FFO that exceeds the new hurdle rate. However, in no event shall the incentive fee for a particular quarter exceed by 15.0% (the cap) the average quarterly incentive fee paid by us for the previous four quarters (excluding quarters for which no incentive fee was paid). Core FFO (as defined in the Advisory Agreement) is GAAP net income (loss) available to common stockholders, excluding the incentive fee, depreciation and amortization, any realized and unrealized gains, losses or other non-cash items recorded in net income (loss) available to common stockholders for the period, and one-time events pursuant to changes in GAAP.


The incentive fee prior to the July 2015 amendment rewarded the Adviser in circumstances where our quarterly funds from operations, or FFO, before giving effect to any incentive fee, or pre-incentive fee FFO, exceeded 1.75%, or 7.0% annualized, or the hurdle rate, of common stockholders’ equity. FFO, included any realized capital gains and capital losses, less any distributions paid on preferred stock and Senior Common Stock, but FFO did not include any unrealized capital gains or losses (including impairment charges). The Adviser received 100.0% of the amount of the pre-incentive fee FFO that exceeded the hurdle rate, but was less than 2.1875% of our common stockholders’ equity. The Adviser also received an incentive fee of 20.0% of the amount of our pre-incentive fee FFO that exceeded 2.1875% of common stockholders’ equity.

For the three and nine months ended September 30,March 31, 2018 and 2017, we recorded an incentive fee of $0.6$0.7 million and $1.8 million, respectively. For the three and nine months ended September 30, 2016, we recorded an incentive fee of $0.6 million and $1.8 million, respectively. The Adviser did not waive any portion of the incentive fee for the three and nine months ended September 30, 2017March 31, 2018 or 2016. Waivers are unconditional and cannot be recouped by the Adviser in the future.2017.

Capital Gain Fee

Under the Advisory Agreement, as amended in July 2015, we will pay to the Adviser a capital gains-based incentive fee that will be calculated and payable in arrears as of the end of each fiscal year (or upon termination of the Advisory Agreement). In determining the capital gain fee, we will calculate aggregate realized capital gains and aggregate realized capital losses for the applicable time period. For this purpose, aggregate realized capital gains and losses, if any, equals the realized gain or loss calculated by the difference between the sales price of the property, less any costs to sell the property and the current gross value of the property (which is calculated as the original acquisition price plus any subsequent non-reimbursed capital improvements). At the end of the fiscal year, if this number is positive, then the capital gain fee payable for such time period shall equal 15.0% of such amount. No capital gain fee was recognized during the three and nine months ended September 30, 2017March 31, 2018 or 2016.

On January 10, 2017, we amended and restated the Advisory Agreement by entering into the Fourth Amended and Restated Investment Advisory Agreement between us and the Adviser to revise the calculation of the capital gains fee. Based upon the amendment, the calculation of the capital gains fee is based on the all-in acquisition cost of disposed of properties. The impact of this amendment would not have resulted in a capital gains fee for previously reported periods.2017.

Termination Fee

The Advisory Agreement includes a termination fee whereby, in the event of our termination thereof without cause (with 120 days’ prior written notice and the vote of at least two-thirds of our independent directors), a termination fee would be payable to the Adviser equal to two times the sum of the average annual base management fee and incentive fee earned by the Adviser during the 24-month period prior to such termination. A termination fee is also payable if the Adviser terminates the Advisory Agreement after we have defaulted and applicable cure periods have expired. The Advisory Agreement may also be terminated for cause by us (with 30 days’ prior written notice and the vote of at least two-thirds of our independent directors), with no termination fee payable. Cause is defined in the agreement to include if the Adviser breaches any material provisions thereof, the bankruptcy or insolvency of the Adviser, dissolution of the Adviser and fraud or misappropriation of funds.

Administration Agreement

Under the terms of the Administration Agreement, we pay separately for our allocable portion of the Administrator’s overhead expenses in performing its obligations to us including, but not limited to, rent and our allocable portion of the salaries and benefits expenses of our Administrator’s employees, including, but not limited to, our chief financial officer, treasurer, chief compliance officer, general counsel and secretary (who also serves as our Administrator’s president, general counsel and secretary), and their respective staffs. Our allocable portion of the Administrator’s expenses are generally derived by multiplying our Administrator’s total expenses by the approximate percentage of time the Administrator's employees perform services for us in relation to their time spent performing services for all companies serviced by our Administrator under contractual agreements. For the three and nine months ended September 30,March 31, 2018 and 2017, we recorded an administration fee of $0.3$0.4 million and $1.0 million, respectively, and for the three and nine months ended September 30, 2016, we recorded an administration fee of $0.3 million and $1.1$0.4 million, respectively.

Gladstone Securities

Gladstone Securities, LLC, or ("Gladstone Securities,Securities"), is a privately held broker dealer registered with the Financial Industry Regulatory Authority and insured by the Securities Investor Protection Corporation. Gladstone Securities is an affiliate of ours, as its parent company is owned and controlled by Mr. David Gladstone, our chairman and chief executive officer. Mr. Gladstone also serves on the board of managers of Gladstone Securities.

Mortgage Financing Arrangement Agreement

We entered into an agreement with Gladstone Securities, effective June 18, 2013, for it to act as our non-exclusive agent to assist us with arranging mortgage financing for properties we own.own (the "Financing Arrangement Agreement"). In connection with this engagement, Gladstone Securities will, from time to time, continue to solicit the interest of various commercial real estate lenders or recommend to us third party lenders offering credit products or packages that are responsive to our needs. We pay Gladstone Securities a financing fee in connection with the services it provides to us for securing mortgage financing on any of our properties. The amount of these financing fees, which are payable upon closing of the financing, are based on a percentage of the amount of the mortgage, generally ranging from 0.15% to a maximum of 1.0% of the mortgage obtained. The amount of the financing fees may be reduced or eliminated, as determined by us and Gladstone Securities, after taking into consideration various factors, including, but not limited to, the involvement of any third party brokers and market conditions. We paid financing fees to Gladstone Securities of $0.1 million and $0.2$0.02 million during the three and nine months ended September 30, 2017, respectively, which are included in mortgage notes payable, net, in the consolidated balance sheets, or 0.25% and 0.27%, respectively, of mortgage principal secured. We paid financing fees to Gladstone Securities of $0.1 million and $0.2 million during the three and nine months ended September 30, 2016, respectively,March 31, 2018, which are included in mortgage notes payable, net, in the condensed consolidated balance sheets, or 0.28% and 0.36%, respectively,0.25% of the mortgage principal secured.secured, and did not pay financing fees to Gladstone Securities during the three months ended March 31, 2017. Our Board of Directors renewed the agreementFinancing Arrangement Agreement for an additional year, through August 31, 2018, at its July 2017 meeting.


3. LossEarnings per Share of Common Stock

The following tables set forth the computation of basic and diluted lossearnings per share of common stock for the three and nine months ended September 30, 2017March 31, 2018 and 2016.2017. We computed basic lossearnings per share for the three and nine months ended September 30,March 31, 2018 and 2017 and 2016 using the weighted average number of shares outstanding during the periods. Diluted lossearnings per share for the three and nine months ended September 30,March 31, 2018 and 2017, and 2016, reflects additional shares of common stock, related to our convertible Seniorsenior common stock (the "Senior Common Stock (ifStock"), if the effect would be dilutive),dilutive, that would have been outstanding if dilutive potential shares of common stock had been issued, as well as an adjustment to net income available to common stockholders as applicable to common stockholders that would result from their assumed issuance (dollars in thousands, except per share amounts).

Acquisitions

AcquisitionsWe acquired one property during the ninethree months ended September 30, 2016 were accounted for as business combinations in accordance with Accounting Standards Codification (“ASC”) 805 “Business Combinations” (“ASC 805”), as there was a prior leasing history on the property. The fair value of all assets acquiredMarch 31, 2018, and liabilities assumed were determined in accordance with ASC 805, and all acquisition-related costs were expensed as incurred. Commencing in the fourth quarter of 2016, we early adopted Accounting Standards Update (“ASU”) 2017-01, “Clarifying the Definition of a Business” (“ASU 2017-01”), which narrows the scope of transactions that would be accounted under ASC 805. Under ASU 2017-01, if substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the grouping is not a business, and rather an asset acquisition. Beginning in the fourth quarter 2016, acquisitions have been deemed an asset acquisition when evaluated under the new guidance, and all acquisition-related costs have been capitalized.

We acquired fivezero properties during the ninethree months ended September 30,March 31, 2017, and two properties during the nine months ended September 30, 2016, which areis summarized below (dollars in thousands):

(1)On June 22, 2017,March 9, 2018, we acquired a 60,016127,444 square foot property in Conshohocken, PennsylvaniaVance, Alabama for $15.7$14.3 million. We assumed $11.2 million of mortgage debt in connection with this acquisition. The annualized GAAP rent on the 8.59.8 year lease is $1.7 million. On July 7, 2017, we acquired a 300,000 square foot property in Philadelphia, Pennsylvania for $27.1 million. We issued $14.9 million of mortgage debt with a fixed interest rate of 3.75% in connection with this acquisition. The annualized GAAP rent on the 15.4 year lease is $2.3 million. On July 31, 2017, we acquired a 306,435 square foot three property portfolio located in Maitland, Florida for $51.6 million. We issued $28.8 million of mortgage debt with a fixed interest rate of 3.89% in connection with this acquisition. This portfolio has a weighted average lease term of 8.6 years, and annualized GAAP rent of $6.8$1.1 million.
(2)On May 26, 2016, we acquiredWe accounted for this transaction under ASU 2017-01, "Clarifying the Definition of a 107,062 square foot property in Salt Lake City, Utah for $17.0 million. We borrowed $9.9 million to fund the acquisition. The annualized GAAP rent on the 6.0 year lease is $1.4 million. On September 12, 2016, we acquired a 119,224 square foot property in Fort Lauderdale, Florida for $23.9 million. We borrowed $14.1 million to fund the acquisition. The annualized GAAP rent on the 9.0 year lease is $2.0 million.
(3)We early adopted ASU 2017-01.Business." As a result, we treated our acquisitionsacquisition during the ninethree months ended September 30, 2017March 31, 2018 as an asset acquisitionsacquisition rather than a business combinations.combination. As a result of this treatment, we capitalized $1.2$0.1 million of acquisition costs that would otherwise have been expensed under business combination treatment.

(4)We assumed an interest rate swap in connection with $11.2 million of assumed debt on our Conshohocken, Pennsylvania acquisition, in which we will pay our counterparty a fixed interest rate of 1.80%, and receive a variable interest rate of one month LIBOR from our counterparty. Our interest expense exposure is fixed at 3.55%. The interest rate swap had a fair value of $0.04 million upon the date of assumption, and subsequently increased in value to $0.2 million at September 30, 2017. We have elected to treat this interest rate swap as a cash flow hedge, and all changes in fair market value will be recorded to accumulated other comprehensive income on the condensed consolidated balance sheets.

We determined the fair value of assets acquired and liabilities assumed related to the propertiesproperty acquired during the ninethree months ended September 30, 2017 and 2016March 31, 2018 as follows (dollars in thousands):

Real Estate Dispositions

During the ninethree months ended September 30, 2017,March 31, 2018, we continued to execute our capital recycling program, whereby we sold non-core properties outside of our core markets and redeployed proceeds to fund property acquisitions in our target secondary growth markets, as well as repay outstanding debt. During the ninethree months ended September 30, 2017,March 31, 2018, we sold fourtwo non-core properties located in Franklin, New Jersey, Hazelwood, Missouri, Concord Township, Ohio,Arlington, Texas and Newburyport,Tewksbury, Massachusetts, which are summarized in the table below (dollars in thousands):

Real Estate Held for Sale

At September 30, 2017,March 31, 2018, we did not have any propertieshad one property classified as held for sale.sale, located in South Hadley, Massachusetts. We have identified a prospective buyer for this property, and we are currently negotiating a purchase and sale agreement. At December 31, 2016,2017, we had two properties classified as held for sale, located in Hazelwood, MissouriArlington, Texas and Franklin, New Jersey.Tewksbury, Massachusetts. Both of these properties were sold during the ninethree months ended September 30, 2017.March 31, 2018.

Impairment Charges

We evaluated our portfolio for triggering events to determine if any of our held and used assets were impaired during the ninethree months ended September 30, 2017March 31, 2018 and identified twodid not identify any held and used assets which were impaired during first quarter 2017. We did not identify any impairment on held and used assets during the second or third quarter of 2017. For these properties, during first quarter 2017, we received unsolicited interest from potential buyers, and as a result, we included a sale scenario and shortened our hold period when comparing the undiscounted cash flows against the respective carrying values. Based upon our analysis, we concluded that the undiscounted cash flows for these properties were below their respective carrying values indicating that these assets were impaired as of March 31, 2017, and accordingly, we recorded an impairment charge of $3.7 million during the three months ended March 31, 2017. During the three months ended June 30, 2017, we sold one of these impaired properties to the tenant for a further loss on sale of $1.8 million. During the second quarter of 2017, we became aware of a decline in the tenant's financial results. The tenant expressed interest in acquiring our property as part of their corporate reorganization. Due to the re-tenanting risk of the property if it were to go vacant and as the location was in a non-core market, we executed a sale with this tenant. We sold the other impaired property during the three months ended September 30, 2017, recognizing a gain on sale of $1,000.impaired.

We did not classify any propertiesclassified one property as held for sale at September 30, 2017. During our previous two quarters where we had held for sale activity, weMarch 31, 2018. We performed an analysis of all propertiesthe property classified as held for sale, and compared the fair market value of the asset less selling costs against the carrying value of assets available for sale. We recordeddid not record an impairment charge of $0.3 million during the three months ended June 30, 2017 to reduceMarch 31, 2018, as the fair market value was greater than the carrying value equal to the sales price per the executed purchase and sale agreement, less estimated selling costs.value.

Fair market value for these assetsthis asset was calculated using Level 3 inputs (defined in Note 6 "Mortgage Notes Payable and Credit Facility"), which were determined using comparable asset sale data from the respective asset locations,location as well as sales prices from an executed purchase and sale agreement.negotiations with a prospective buyer. We continue to evaluate our properties on a quarterly basis for changes that could create the need to record impairment. Future impairment losses may result, and could be significant, should market conditions deteriorate in the markets in which we hold our assets or we are unable to secure leases at terms that are favorable to us, which could impact the estimated cash flow of our properties over the period in which we plan to hold our properties. Additionally, changes in management’s decisions to either own and lease long-term or sell a particular asset will have an impact on this analysis.

We recognized $2.0$3.7 million of impairment charges on fivetwo properties during the ninethree months ended September 30, 2016.March 31, 2017. These properties were impaired through our held for sale carrying value analysis, during the three and nine months ended September 30, 2016,March 31, 2017, and we concluded that the fair market value less selling costs was below the carrying value of this property.the respective properties. We have sold fourboth of these properties and one of these properties is classified as a held and used asset during the three and nine monthsyear ended September 30,December 31, 2017.

The fair values for the above held for sale property was calculated using Level 3 inputs which were calculated using an estimated sales price, less estimated costs to sell. The estimated sales price was determined using an executed purchase and sale agreement.

6. Mortgage Note Receivable

On July 25, 2014, we closed a $5.6 million second mortgage development loan for the construction of an 81,371 square foot, build-to-suit transitional care facility located on a major hospital campus in Phoenix, Arizona. Subsequently, on April 14, 2015, we closed an additional $0.3 million interim financing loan for the development of the Phoenix, Arizona property. Construction was completed in July 2015 and we earned 9.0% interest, paid currently in cash, on the loan during construction and through maturity. Prior to completion of the facility, we were granted a right of first offer to purchase the property at fair value. We elected not to purchase the property, and received an exit fee upon maturity of the loan in an amount sufficient for us to earn an internal rate of return of 22.0% on the second mortgage development loan, inclusive of interest earned. The principal balance of the loans and all associated interest income and exit fee revenue was received in January 2016. We did not recognize any interest income or exit fee revenue during the three and nine months ended September 30, 2017. We recognized $0.0 million and $0.4 million in both cash interest income and exit fee revenue during the three and nine months ended September 30, 2016, respectively. We currently have no mortgage notes receivable outstanding.

Interest Rate Cap and Interest Rate Swap Agreements

We have entered into interest rate cap agreements that cap the interest rate on certain of our variable-rate debt and we have assumed anor entered into interest rate swap agreementagreements in which we hedged our exposure to variable interest rates by agreeing to pay fixed interest rates to our respective counterparty. We have adopted the fair value measurement provisions for our financial instruments recorded at fair value. The fair value guidance establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Generally, we will estimate the fair value of our interest rate caps and interest rate swap, in the absence of observable market data, using estimates of value including estimated remaining life, counterparty credit risk, current market yield and interest rate spreads of similar securities as of the measurement date. At September 30, 2017March 31, 2018 and December 31, 2016,2017, our interest rate cap agreements and interest rate swap were valued using Level 2 inputs.

The fair value of all mortgage notes payable outstanding as of September 30, 2017March 31, 2018 was $461.8$440.5 million, as compared to the carrying value stated above of $455.4$442.8 million. The fair value is calculated based on a discounted cash flow analysis, using management’s estimate of market interest rates on long-term debt with comparable terms and loan to value ratios. The fair value was calculated using Level 3 inputs of the hierarchy established by ASC 820, “Fair Value Measurements and Disclosures.”

Credit Facility

InOn August 7, 2013, we procured a senior unsecured revolving credit facility, or theour Revolver with KeyBank National Association (“KeyBank”) (serving as arevolving lender, a letter of credit issuer and an administrative agent). OnIn October 5, 2015, we expanded our Revolver to $85.0 million extended the maturity date one year through August 2018, withand entered into a one-year extension option through August 2019. We alsoTerm Loan whereby we added a $25.0 million, term loan facility, or thefive-year Term Loan which matures in October 2020. The Revolver and the Term Loan are referred to collectively herein as the Credit Facility. The interest rate on the Revolver was also reduced by 25 basis points at each of the leverage tiers and the total maximum commitment under the Credit Facility was increased from $100.0 million to $150.0 million. We also added three new lenders to the bank syndicate, which is now comprised of KeyBank, Comerica Bank, Fifth Third Bank, US Bank and Huntington Bank.

The Term Loan is subject to the same leverage tiers as the Revolver; howeverRevolver, with the interest rate at each leverage tier isbeing five basis points lower. We have the option to repay the Term Loan in full, or in part, at any time without penalty or premium prior to the maturity date. On October 27, 2017, we amended our existing Credit Facility. The Term Loan component of the Credit Facility was increased from $25.0 million, to $75.0 million, with the Revolver commitment remaining at $85.0 million. The Term Loan has a new five-year term, with a maturity date of October 27, 2022, and the Revolver has a new four-year term, with a maturity date of October 27, 2021. The interest rate for the Credit Facility was reduced by 25 basis points at each of the leverage tiers. We entered into interest rate cap agreements on the amended Term Loan, which cap LIBOR at 2.75%. We used the net proceeds of the amended Credit Facility to repay all previously existing borrowings under the Revolver. We incurred fees of approximately $0.9 million in connection with the Credit Facility amendment. The bank syndicate is now comprised of KeyBank, Fifth Third Bank, US Bank National Association and The Huntington National Bank.

As of September 30, 2017,March 31, 2018, there was $69.2$107.7 million outstanding under our Credit Facility at a weighted average interest rate of approximately 3.22%3.60% and $1.0 million outstanding under letters of credit at a weighted average interest rate of 2.00%1.75%. As of September 30, 2017,March 31, 2018, the maximum additional amount we could draw under the Revolver was $34.0$46.3 million. We were in compliance with all covenants under the Credit Facility as of September 30, 2017.March 31, 2018.

The amount outstanding under the Credit Facility approximates fair value as of September 30, 2017.March 31, 2018.

8. Mandatorily Redeemable Term Preferred Stock

In February 2012, we completed a public offering of 1,540,000 shares of 7.125% Series C Cumulative Term Preferred Stock (“Term Preferred Stock”), par value $0.001 per share, at a public offering price of $25.00 per share. Gross proceeds of the offering totaled $38.5 million and net proceeds, after deducting offering expenses borne by us, were $36.7 million. The shares of the Term Preferred Stock had a mandatory redemption date of January 31, 2017. During the year ended December 31, 2016, we redeemed all outstanding shares of the Term Preferred Stock. Accordingly, we wrote-off unamortized offering costs of $0.2 million during the year ended December 31, 2016, which were recorded to interest expense in our condensed consolidated statements of operations and other comprehensive income (loss).

The Term Preferred Stock was recorded as a liability in accordance with ASC 480, “Distinguishing Liabilities from Equity,” which states that mandatorily redeemable financial instruments should be classified as liabilities and therefore the related dividend payments are treated as a component of interest expense in the condensed consolidated statements of operations and other comprehensive income (loss).

Recent Activity

Common Stock Offering

In July 2017, we completed an overnight offering of 1.2 million shares of our common stock, at a public offering price of $20.52 per share. Net proceeds, after deducting underwriter discounts, were $22.7 million. The proceeds from this offering were used to acquire real estate, repay existing indebtedness, and for other general corporate purposes. The offering's underwriters exercised their overallotment option, purchasing an additional 0.2 million shares of our common stock at the public offering price of $20.52 per share. Net proceeds from exercise of the option to purchase additional shares, after deducting underwriter discounts, were $3.4 million. The proceeds from this overallotment were also used to acquire real estate, repay existing indebtedness, and for other general corporate purposes.

Common Stock ATM Program

In February 2016,During the three months ended March 31, 2018, we amendedsold 0.03 million shares of common stock, raising $0.6 million in net proceeds under our common ATM program with Cantor Fitzgerald (the “Common"Common Stock ATM Program”Program"). The amendment increased the amount of shares of common stock that we may offer and sell through Cantor Fitzgerald, to $160.0 million. All other material terms of the Common Stock ATM program remained unchanged. During the nine months ended September 30, 2017, we sold 1.5 million shares of common stock, raising $30.8 million in net proceeds under the Common Stock ATM Program. As of September 30, 2017,March 31, 2018, we had a remaining capacity to sell up to $101.1$85.6 million of common stock under the Common Stock ATM Program.

Series A and B Preferred Stock ATM Programs

In February 2016, we entered into anUnder our open market sales agreement with Cantor Fitzgerald (the “Series A and B Preferred ATM Program”), pursuant to which we may, from time to time, offer to sell (i) shares of our 7.75% Series A Cumulative Redeemable Preferred Stock (“Series A Preferred”), and (ii) shares of our 7.50% Series B Cumulative Redeemable Preferred Stock (“Series B Preferred”), having an aggregate offering price of up to $40.0 million, through Cantor Fitzgerald, acting as sales agent and/or principal. We did not sell any shares of our Series A Preferred or Series B Preferred during the ninethree months ended September 30, 2017.March 31, 2018. As of September 30, 2017,March 31, 2018, we had a remaining capacity to sell up to $37.2 million of preferred stock under the Series A and B Preferred ATM Program.

Mezzanine Equity

The 7.00% Series D Cumulative Redeemable Preferred Stock (“Series D Preferred”), is classified as mezzanine equity in our condensed consolidated balance sheetsheets because it is redeemable at the option of the shareholder upon a change of control of greater than 50% in accordance with ASC 480-10-S99 “Distinguishing Liabilities from Equity,” which requires mezzanine equity classification for preferred stock issuances with redemption features which are outside of the control of the issuer. A change in control of our company, outside of our control, is only possible if a tender offer is accepted by over 90% of our shareholders. All other change in control situations would require input from our Board of Directors. We will periodically evaluate the likelihood that a change of control greater than 50% will take place, and if we deem this probable, we would adjust the Series D Preferred presented in mezzanine equity to their redemption value, with the offset to gain (loss) on extinguishment. We currently believe the likelihood of a change of control greater than 50% is remote.

In June 2016, we entered into anUnder our open market sales agreement with Cantor Fitzgerald (the “Series D Preferred ATM Program”), pursuant to which we may, from time to time, offer to sell shares of our Series D Preferred, having an aggregate offering price of up to $50.0 million, through Cantor Fitzgerald, acting as sales agent and/or principal. During the ninethree months ended September 30, 2017,March 31, 2018, we sold approximately 0.40.04 million shares of our Series D Preferred for net proceeds of $11.2$0.9 million. As of September 30, 2017,March 31, 2018, we had a remaining capacity to sell up to $22.3$19.9 million of Series D Preferred under the Series D Preferred ATM Program.

General

We are an externally-advised real estate investment trust (“REIT”) that was incorporated under the General Corporation Law of the State of Maryland on February 14, 2003. We focus on acquiring, owning, and managing primarily office and industrial properties. On a selective basis, we may make long term industrial and commercial mortgage loans; however, we do not have any mortgage loans currently outstanding. Our properties are geographically diversified and our tenants cover a broad cross section of business sectors and range in size from small to very large private and public companies. We actively communicate with buyout funds, real estate brokers and other third parties to locate properties for potential acquisition or to provide mortgage financing in an effort to build our portfolio. We target secondary growth markets that possess favorable economic growth trends, diversified industries, and growing population and employment.

We have historically entered into, and intend in the future to enter into, purchase agreements primarily for real estate having net leases with remaining terms of approximately 7 to 15 years and built in rental rate increases. Under a net lease, the tenant is required to pay most or all operating, maintenance, repair and insurance costs and real estate taxes with respect to the leased property.

All references to annualized generally accepted accounting principles (“GAAP”) rent are rents that each tenant pays in accordance with the terms of its respective lease reported evenly over the non-cancelable term of the lease.

As of October 31, 2017:May 1, 2018:
 
we owned 9798 properties totaling 11.211.4 million square feet in 24 states;
our occupancy rate was 97.9%99.1%;
the weighted average remaining term of our mortgage debt was 6.66.4 years and the weighted average interest rate was 4.52%4.59%; and
the average remaining lease term of the portfolio was 7.77.4 years.


Business Environment

In the United States, vacancy rates have decreased for both office and industrial properties in most markets, as increased user demand has led to improved conditions. Vacancy rates in many markets have been reduced to levels seen at the peak before the most recent U.S. recession and rental rates have increased in most primary and secondary markets. This condition has led to a rise in construction activity for both office and industrial properties in many markets. Reports from many national research firms reflect that the industrial supply and demand relationship still appears to be in equilibrium, but that office supply and demand in select markets may be moving toward a slight increase in vacancy. Interest rates have been volatile since the beginning of 2016 and although interest rates are still relatively low, lenders have varied on their required spreads over the last several quarters and overall financing costs for fixed rate mortgages appear to be on the rise. At the beginning of the year, several research firm surveys reflected that the current real estate cycle may be peaking from both a volume and price standpoint. 2016The 2017 year-end statistics from national research firms indicate that total investment sales volume was approximately 10%8-10% less than the volume recorded in 2015. That reduction continued through2016. We believe that the second quarter ofQ1 2018 investment volume was lower than Q1 2017 as research firms reportedvolume, based on our market observations; however, industry publications containing this data have not yet been released. These statistics, once confirmed by industry reports, reflect that investment volumesales volumes have dropped for the quarter was nearly 10% less thanpast two years compared to the level for the first six months of 2016.preceding year.

From a more macro-economic perspective, the strength of the global economy and U.S. economy in particular continue to be uncertain with increased volatility due to the 2016 vote last year in the United Kingdom to exit the European Union, the uncertainty of health care and tax reform initiatives in the United States, and an apparent continuing global economic slowdown. In addition,The long-term impact of the recent passage of tax reform in the United States is unknown at this time, although the lowering of the corporate tax rate is generally expected be beneficial. Finally, the continuing uncertainty surrounding the ability of the federal government to address its fiscal condition in both the near and long term as well as other geo-political issues has increased domestic and global instability. These developments could cause interest rates and borrowing costs to rise, which may adversely affect our ability to access both the equity and debt markets and could have an adverse effect on our tenants as well.

We continue to focus on re-leasing vacant space, renewing upcoming lease expirations, re-financing upcoming loan maturities, and acquiring additional properties with associated long-term leases. Currently, we only have one fully vacant building, located in Tewksbury, Massachusetts, as well as a total of two partially vacant buildings. Our Newburyport, Massachusetts property, which was previously fully vacant, was classified as held for sale as of June 30, 2017, and subsequently sold in August 2017.

We have one leasezero leases expiring during the remainder of 2018, six leases expiring in 2017,2019, which accounts for 0.04%3.9% of rental revenue we recognized during the ninethree months ended September 30, 2017March 31, 2018, and one lease12 leases expiring in 2018,2020, which accounts for 0.1%11.3% of rental revenue recognized during the ninethree months ended September 30, 2017.March 31, 2018.

Our available vacant space at September 30, 2017March 31, 2018 represents 2.1%0.9% of our total square footage and the annual carrying costs on the vacant space, including real estate taxes and property operating expenses, are approximately $0.6$0.2 million. We continue to actively seek new tenants for these properties.

Our ability to make new investments is highly dependent upon our ability to procure financing. Our principal sources of financing generally include the issuance of equity securities, long-term mortgage loans secured by properties, borrowings under our $85.0 million senior unsecured revolving credit facility (“Revolver”), with KeyBank National Association (serving as a revolving lender, a letter of credit issuer and an administrative agent), which matures in October 2021, and our $75.0 million term loan facility (“Term Loan”), which matures in October 2022, which we refer to collectively herein as the Credit Facility. While lenders’ credit standards have tightened, we continue to look to national and regional banks, insurance companies and non-bank lenders, in addition to the collateralized mortgage backed securities market, or the CMBS market,(the "CMBS market"), to issue mortgages to finance our real estate activities.

In addition to obtaining funds through borrowing, we have been active in the equity markets during and subsequent to the ninethree months ended September 30, 2017.March 31, 2018. We completed an overnight offering of our common stock, and we have also issued shares of both common stock and Series D Preferred Stock through our at-the-market programs, or ATM Programs, pursuant to our open market sale agreements with Cantor Fitzgerald, discussed in more detail below.

Advisory and Administration Agreements

We are externally managed pursuant to contractual arrangements with our Adviser and our Administrator, which collectively employ all of our personnel and pay their salaries, benefits and general expenses directly. Both our Adviser and Administrator are affiliates of ours, as their parent company is owned and controlled by Mr. David Gladstone, our chairman and chief executive officer. Two of our executive officers, Mr. Gladstone and Mr. Terry Brubaker (our vice chairman and chief operating officer) serve as directors and executive officers of our Adviser and our Administrator. Mr. Michael LiCalsi, our general counsel and secretary, serves as our Administrator’s president, general counsel and secretary. We have entered into an advisory agreement with our Adviser, or the Advisory Agreement,as amended from time to time (the "Advisory Agreement"), and an administration agreement with our Administrator or the Administration Agreement.(the "Administration Agreement"). The services and fees under the Advisory Agreement and Administration Agreement are described below.


Under the terms of the Advisory Agreement, between us and our Adviser, as amended, we are responsible for all expenses incurred for our direct benefit. Examples of these expenses include legal, accounting, interest, directors’ and officers’ insurance, stock transfer services, stockholder-related fees, consulting and related fees. In addition, we are also responsible for all fees charged by third parties that are directly related to our business, which include real estate brokerage fees, mortgage placement fees, lease-up fees and transaction structuring fees (although we may be able to pass all or some of such fees on to our tenants and borrowers).

Base Management Fee

On July 24, 2015,January 10, 2017, we entered into a Second Amended and Restated Advisory Agreement with the Adviser, effective July 1, 2015. We subsequently entered into a Third Amended and Restated Advisory Agreement with the Adviser on July 12, 2016, effective July 1, 2016, and, as described below, a Fourth Amended and Restated Investment Advisory Agreement with the Adviser, on January 10, 2017, effective as of October 1, 2016. Our entrance into the Advisory Agreement and each subsequent amendment thereof (including the fourth amendment completed in January of the amended Advisory Agreements2017) was approved unanimously by our Board of Directors. Our Board of Directors also reviews and considers renewing the agreement with our AdviserAdvisory Agreement each July. As such, duringDuring its July 2017 meeting, theour Board of Directors reviewed and renewed the Advisory Agreement for an additional year, through August 31, 2018.

As a result ofUnder the July 2015 amendment,Advisory Agreement, the calculation of the annual base management fee equals 1.5% of our adjusted total stockholders’ equity, which is our total stockholders’ equity plus total mezzanine equity (before giving effect to the base management fee and incentive fee), adjusted to exclude the effect of any unrealized gains or losses that do not affect realized net income (including impairment charges) and adjusted for any one-time events and certain non-cash items (the later to occur for a given quarter only upon the approval of our Compensation Committee). The fee is calculated and accrued quarterly as 0.375% per quarter of such adjusted total stockholders’ equity figure. As a result of the July 2016 amendment, the definition of adjusted total stockholders’ equity in the calculation of the base management fee and the incentive fee (described below) includes total mezzanine equity. Our Adviser does not charge acquisition or disposition fees when we acquire or dispose of properties as is common in other externally managed REITs; however, our Adviser may earn fee income from our borrowers, tenants or other sources. Prior to the 2015 amendment, our Advisory Agreement provided for an annual base management fee equal to 2.0% of our common stockholders’ equity, which was our total stockholders’ equity, less the recorded value of any preferred stock and adjusted to exclude the effect of any unrealized gains, losses, or other items that did not affect realized net income (including impairment charges).


Incentive Fee

As a result ofPursuant to the 2015 amendment,Advisory Agreement, the calculation of the incentive fee was revised to rewardrewards the Adviser in circumstances where our quarterly Core FFO (defined at the end of this paragraph), before giving effect to any incentive fee, or pre-incentive fee Core FFO, exceeds 2.0% quarterly, or 8.0% annualized, of adjusted total stockholders’ equity (after giving effect to the base management fee but before giving effect to the incentive fee). We refer to this as the new hurdle rate. The Adviser will receive 15.0% of the amount of our pre-incentive fee Core FFO that exceeds the new hurdle rate. However, in no event shall the incentive fee for a particular quarter exceed by 15.0% (the cap) the average quarterly incentive fee paid by us for the previous four quarters (excluding quarters for which no incentive fee was paid). Core FFO (as defined in the Advisory Agreement) is GAAP net income (loss) available to common stockholders, excluding the incentive fee, depreciation and amortization, any realized and unrealized gains, losses or other non-cash items recorded in net income (loss) available to common stockholders for the period, and one-time events pursuant to changes in GAAP.

The incentive fee prior to the July 2015 amendment rewarded the Adviser in circumstances where our quarterly funds from operations, or FFO, before giving effect to any incentive fee, or pre-incentive fee FFO, exceeded 1.75%, or 7.0% annualized, or the hurdle rate, of common stockholders’ equity. FFO included any realized capital gains and capital losses, less any distributions paid on preferred stock and Senior Common Stock (defined herein), but FFO did not include any unrealized capital gains or losses (including impairment charges). The Adviser received 100.0% of the amount of the pre-incentive fee FFO that exceeded the hurdle rate, but was less than 2.1875% of our common stockholders’ equity. The Adviser also received an incentive fee of 20.0% of the amount of our pre-incentive fee FFO that exceeded 2.1875% of common stockholders’ equity.

Capital Gain Fee

Under the Advisory Agreement, as amended in July 2015, we will pay to the Adviser a capital gains-based incentive fee that will be calculated and payable in arrears as of the end of each fiscal year (or upon termination of the Advisory Agreement). In determining the capital gain fee, we will calculate aggregate realized capital gains and aggregate realized capital losses for the applicable time period. For this purpose, aggregate realized capital gains and losses, if any, equals the realized gain or loss calculated by the difference between the sales price of the property, less any costs to sell the property and the current gross value of the property (which is calculated as the original acquisition price plus any subsequent non-reimbursed capital improvements). At the end of the fiscal year, if this number is positive, then the capital gain fee payable for such time period shall equal 15.0% of such amount. No capital gain fee was recognized during the three and nine months ended September 30, 2017March 31, 2018 or 2016.

On January 10, 2017, we amended and restated the Advisory Agreement by entering into the Fourth Amended and Restated Investment Advisory Agreement between us and the Adviser to revise the calculation of the capital gains fee. Based upon the amendment, the calculation of the capital gains fee is based on the all-in acquisition cost of disposed of properties. The impact of this amendment would not have resulted in a capital gains fee for previously reported periods. Our entrance into the Fourth Amended and Restated Investment Advisory Agreement was approved unanimously by our Board of Directors.2017.

Termination Fee

The Advisory Agreement includes a termination fee whereby, in the event of our termination of the agreement without cause (with 120 days’ prior written notice and the vote of at least two-thirds of our independent directors), a termination fee would be payable to the Adviser equal to two times the sum of the average annual base management fee and incentive fee earned by the Adviser during the 24-month period prior to such termination. A termination fee is also payable if the Adviser terminates the agreement after the Company has defaulted and applicable cure periods have expired. The agreement may also be terminated for cause by us (with 30 days’ prior written notice and the vote of at least two-thirds of our independent directors), with no termination fee payable. Cause is defined in the agreement to include if the Adviser breaches any material provisions of the agreement, the bankruptcy or insolvency of the Adviser, dissolution of the Adviser and fraud or misappropriation of funds.


Administration Agreement

Under the terms of the Administration Agreement, we pay separately for our allocable portion of our Administrator’s overhead expenses in performing its obligations to us including, but not limited to, rent and our allocable portion of the salaries and benefits expenses of our Administrator’s employees, including, but not limited to, our chief financial officer, treasurer, chief compliance officer, general counsel and secretary (who also serves as our Administrator’s president, general counsel and secretary), and their respective staffs. As approved by our Board of Directors, effective July 1, 2014, ourOur allocable portion of the Administrator’sAdministrator's expenses are generally derived by multiplying our Administrator’sAdministrator's total expenses by the approximateappropriate percentage of time the Administrator’sAdministrator's employees perform services for us in relation to their time spent performing services for all companies serviced by our Administrator under contractual agreements. We believe that the new methodology of allocating the Administrator’s total expenses by approximate percentage of time services were performed among all companies serviced by our Administrator more closely approximates fees paid to actual services performed.

Critical Accounting Policies and Estimates

The preparation of our financial statements in accordance with GAAP, requires management to make judgments that are subjective in nature in order to make certain estimates and assumptions. Application of these accounting policies involves the exercise of judgment regarding the use of assumptions as to future uncertainties, and as a result, actual results could materially differ from these estimates. A summary of all of our significant accounting policies is provided in Note 1 to our consolidated financial statements in our 2016Annual Report on Form 10-K.10-K for the year ended December 31, 2017, filed by us with the U.S. Securities and Exchange Commission (the "SEC") on February 14, 2018 (our "2017 Form 10-K"). There were no material changes to our critical accounting policies or estimates during the ninethree months ended September 30, 2017.March 31, 2018.

Results of Operations

The weighted average yield on our total portfolio, which was 8.8% and 8.6% as of both September 30,March 31, 2018 and 2017, and 2016,respectively, is calculated by taking the annualized straight-line rents, reflected as rental income on our condensed consolidated statements of operations and other comprehensive income, (loss), of each acquisition since inception as a percentage of the acquisition cost plus subsequent capital improvements. The weighted average yield does not account for the interest expense incurred on the mortgages placed on our properties.

Property operating expenses consist of franchise taxes, property management fees, insurance, ground lease payments, property maintenance and repair expenses paid on behalf of certain of our properties. The decreaseincrease in property operating expenses for same store properties for the three and nine months ended September 30, 2017,March 31, 2018, as compared to the three and nine months ended September 30, 2016,March 31, 2017, is a result of an overall decreaseincrease in property operating expenses incurred at our properties with tenants on base year expense stop leases, offset by an increase in landlord obligated property expenses on our triple net leased properties. The decrease in property operating expenses for same store properties for the nine months ended September 30, 2017, as compared to the nine months ended September 30, 2016 is a result of a decrease in property operating expenses on our properties with base year expense stop leases, offset by an increase in landlord obligated property expenses on our triple net leased properties. The increase in property operating expenses for acquired and disposed of properties for the three and nine months ended September 30, 2017,March 31, 2018, as compared to the three and nine months ended September 30, 2016,March 31, 2017, is primarily a result of increased property operating expenses from properties acquired subsequent to September 30, 2016,March 31, 2017, as a majority of these properties are subject to base year leases, partially offset by an eliminationa reduction of operating expenses from properties sold subsequent to September 30, 2016.March 31, 2017. The increasedecrease in property operating expenses for properties with vacancy during the three and nine months ended September 30, 2017,March 31, 2018, as compared to the three and nine months ended September 30, 2016,March 31, 2017, is due to increaseddecreased property operating expenses from one property which went fullyassociated with three properties where we leased vacant during second quarter 2017, partially offset by executingspace with triple net leases for vacant space for three properties which had partial vacancy during the three and nine months ended September 30, 2017.leases.

The base management fee paid to the Adviser increased for the three and nine months ended September 30, 2017,March 31, 2018, as compared to the three and nine months ended September 30, 2016, because ofMarch 31, 2017, due to the increase in total adjusted stockholders’ equity in the past 12 months. The calculation of the base management fee is described in detail above in “Advisory and Administration Agreements.”

The incentive fee paid to the Adviser increased for the three months ended September 30, 2017March 31, 2018 as compared to the three months ended September 30, 2016, becauseMarch 31, 2017, due to pre-incentive fee Core FFO increasedincreasing faster than the hurdle rate, resulting in a higher incentive fee. The increase in FFO is a result of an increase in total operating revenues, coupled with a decrease in interest expense,partially offset by an increase in total operating expenses. The incentive fee paid to the Adviser decreased for the nine months ended September 30, 2017, as compared to the nine months ended September 30, 2016, because the hurdle rate increased faster than pre-incentive fee FFO, resulting in a lower incentive fee. The increase in the hurdle rate is a result of an increase in total adjusted stockholders’ equity, due to the commonexpenses and preferred shares issued subsequent to September 30, 2016.interest expense. The calculation of the incentive fee is described in detail above in “Advisory and Administration Agreements.”

The administration fee paid to the Administrator decreasedincreased for the three and nine months ended September 30, 2017,March 31, 2018, as compared to the three and nine months ended September 30, 2016,March 31, 2017, due to using a lowergreater share of our administrator’sAdministrator’s resources during the three and nine months ended September 30, 2017.March 31, 2018. The calculation of the administration fee is described in detail above in “Advisory and Administration Agreements.”

General and administrative expenses increased for the three months ended September 30, 2017,March 31, 2018, as compared to the three months ended September 30, 2016,March 31, 2017, primarily as a result of an increase in professional fees and subscription and membership fees, partially offset by a decrease in shareholder related expenses. General and administrative expenses decreased for the nine months ended September 30, 2017, as compared to the nine months ended September 30, 2016, primarily due to a decrease in due diligence expenses that resulted from two asset acquisitions treated as business combinations completed during the nine months ended September 30, 2016, coupled with a decrease in shareholder related expenses, partially offset by an increase in professional fees and subscription and membership fees.

We did not recognize an impairment charge for the three months ended September 30, 2017.March 31, 2018. The impairment charge for the ninethree months ended September 30,March 31, 2017 resulted from an impairment recorded on our Concord Township, Ohio and Newburyport, Massachusetts properties during the first two quartersquarter of 2017, as we determined the carrying value of these properties was unrecoverable through our quarterly impairment testing. Both the Concord Township, Ohio property and the Newburyport, Massachusetts property were sold during the nine monthsyear ended September 30, 2017 for an additional aggregate net loss of $1.8 million. Since the Newburyport, Massachusetts property had been a vacant property with limited releasing prospects, we elected to sell the property to reduce our operating expenses attributable to maintaining a vacant property. The impairment loss for the three and nine months ended September 30, 2016 was from the impairment recorded in connection with two properties during the three months ended September 30, 2016 and impairment charges recorded on five properties during the nine months ended September 30, 2016. Four of the properties impaired during the nine months ended September 30, 2016 have been sold, and one property is currently classified as a held and used asset.

Other Income and Expenses

Interest expense decreasedincreased for the three and nine months ended September 30, 2017,March 31, 2018, as compared to the three and nine months ended September 30, 2016.March 31, 2017. This decreaseincrease was primarily a result of our refinancing of mortgages at lower interest rates and de-leveraging activity, whereby we repaid mortgage notes payable upon maturity using equity and funds from our Revolver, offset by newus issuing or assuming $71.8 million in mortgage debt on properties acquired subsequent to September 30, 2016. While our outstanding mortgage notes payable, net increased from $444.5 million at September 30, 2016 to $450.0 million at September 30, 2017, our weighted average interest rate on mortgage notes payable decreased from 4.71% at September 30, 2016, to 4.52% at September 30, 2017, resulting in interest savings over comparable periods.

Distributions attributable to our 7.125% Series C Cumulative Term Preferred Stock (“Term Preferred Stock”), par value $0.001 per share, decreased for the three and nine months ended September 30, 2017, as compared to the three and nine months ended September 30, 2016, because we redeemedMarch 31, 2017, coupled with an increase in LIBOR, which is the interest rate benchmark for all outstanding shares of our Term Preferred Stockoutstanding variable rate debt, partially offset by our repayment of $65.4 million in August 2016.maturing mortgage debt during and subsequent to the three months ended March 31, 2017.

Gain on sale of real estate, net, for the three months ended September 30, 2017March 31, 2018 is attributable to onetwo non-core industrial assetassets sold during the period. Gain on sale of real estate, net, for the nine months ended September 30, 2017 is attributable to our four non-core office and industrial assets sold during the period. Loss on sale of real estate, net for the three months ended September 30, 2016March 31, 2017 is attributable to one non-core industrial asset sold during the period. Loss


Net Income Available to Common Stockholders

Net income available to common stockholders increased for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, primarily due to the increase in total operating revenues related to asset acquisition activity and leasing vacant space, coupled with a gain on sale of real estate, net, for the nine months ended September 30, 2017 is attributable tofrom selling two non-core industrial assets, sold during the period.

Net Loss Attributable to Common Stockholders

Net loss attributable to common stockholders decreased for both the three and nine months ended September 30, 2017, as compared to the three and nine months ended September 30, 2016, primarily because of the increase in total operating revenues due to asset acquisition activity, coupled with decreased interest expenses due to our refinancing and de-levering activity, as well as capital gains recognized on four property sales, partially offset by an increase in property operating expenses, depreciation and amortization expenses, and base management and incentive fees.

Liquidity and Capital Resources

Overview

Our sources of liquidity include cash flows from operations, cash and cash equivalents, borrowings under our Revolver and issuing additional equity securities. Our available liquidity as of September 30, 2017,March 31, 2018, was $38.3$50.4 million, consisting of $4.3approximately $4.1 million in cash and cash equivalents and an available borrowing capacity of $34.0$46.3 million under our Revolver. Our available borrowing capacity under the Revolver has decreasedincreased to $29.4$48.4 million as of October 31, 2017.May 1, 2018.

Future Capital Needs

We actively seek conservative investments that are likely to produce income to pay distributions to our stockholders. We intend to use the proceeds received from future equity raised and debt capital borrowed to continue to invest in industrial and office real property, make mortgage loans, or pay down outstanding borrowings under our Revolver. Accordingly, to ensure that we are able to effectively execute our business strategy, we routinely review our liquidity requirements and continually evaluate all potential sources of liquidity. Our short-term liquidity needs include proceeds necessary to fund our distributions to stockholders, pay the debt service costs on our existing long-term mortgages, refinancing maturing debt and fund our current operating costs. Our long-term liquidity needs include proceeds necessary to grow and maintain our portfolio of investments.

We believe that our available liquidity is sufficient to fund our distributions to stockholders, pay the debt service costs on our existing long-term mortgages and fund our current operating costs in the near term. We also believe we will be able to refinance our mortgage debt as it matures. Additionally, to satisfy our short-term obligations, we may request credits to our management fees that are issued from our Adviser, although our Adviser is under no obligation to provide any such credits, either in whole or in part. We further believe that our cash flow from operations coupled with the financing capital available to us in the future are sufficient to fund our long-term liquidity needs.


Equity Capital

In July 2017, we completed an overnight offering of 1.2 million shares of our common stock at an offering price of $20.52 per share. Net proceeds, after deducting underwriter discounts, were $22.7 million. The proceeds from this offering were used to acquire real estate, repay existing indebtedness, and for other general corporate purposes. The offering's underwriters exercised their overallotment option, purchasing an additional 0.2 million shares of our common stock at the public offering price of $20.52 per share. Net proceeds from exercise of the option to purchase additional shares, after deducting underwriter discounts, were $3.4 million. The proceeds from this overallotment were used to acquire real estate, repay existing indebtedness, and for other general corporate purposes.

During the ninethree months ended September 30, 2017,March 31, 2018, we raised net proceeds of (i) $30.8$0.6 million of common equity under our Common Stock ATM Program with Cantor Fitzgerald at a grossnet weighted average share price of $21.42,$20.74, and (ii) $11.2$0.9 million under our Series D Preferred ATM Program at a grossnet weighted average share price of $25.54.$24.90. We used these proceeds to pay down outstanding debt and for other general corporate purposes. We did not sell any shares of our Series A Preferred or Series B Preferred pursuant to our Series A and B Preferred ATM Program during the ninethree months ended September 30, 2017.

Subsequent to September 30, 2017 through OctoberMarch 31, 2017, we raised net proceeds of $0.2 million of common equity under our Common Stock ATM Program with Cantor Fitzgerald at a gross weighted average share price of $22.51. We used these proceeds for general corporate purposes. We did not sell any shares of our Series A Preferred, Series B Preferred or Series D Preferred pursuant to our Series A, B and D Preferred ATM Program subsequent to September 30, 2017 through October 31, 2017.2018.

As of October 31, 2017,May 1, 2018, we havehad the ability to raise up to $312.5$293.8 million of additional equity capital through the sale and issuance of securities that are registered under our universal shelf registration statement on Form S-3 (File No. 333-208953), or the Universal Shelf,(the "Universal Shelf"), in one or more future public offerings. Of the $312.5$293.8 million of available capacity under our Universal Shelf, approximately $100.9$85.6 million of common stock is reserved for additional sales under our Common Stock ATM Program, approximately $37.2 million of preferred stock is reserved for additional sales under our Series A and B Preferred ATM Program, and approximately $22.3$18.9 million is reserved for additional sales under our Series D Preferred ATM Program as of October 31, 2017.May 1, 2018. We expect to continue to use our ATM programs as a source of liquidity for the remainder of 2017.2018.

Debt Capital

As of September 30, 2017,March 31, 2018, we had 45 mortgage notes payable in the aggregate principal amount of $455.4$442.8 million, collateralized by a total of 6766 properties with a remaining weighted average maturity of 6.76.4 years. The weighted-average interest rate on the mortgage notes payable as of September 30, 2017March 31, 2018 was 4.52%4.59%.

We continue to see banks and other non-bank lenders willing to issue mortgages. Consequently, we are focused on obtaining mortgages through regional banks, non-bank lenders and the CMBS market.

We have
As of March 31, 2018, we had mortgage debt in the aggregate principal amount of $10.4$36.3 million payable during the remainder of 20172018 and $47.8$47.6 million payable during 2018.2019. The 20172018 principal amounts payable include both amortizing principal payments and onefive balloon principal paymentpayments due in Decemberthe second half of 2017.2018. We anticipate being able to refinance our mortgages that come due during the remainder of 20172018 and 20182019 with a combination of new mortgage debt and the issuance of additional equity securities. In addition, we have raised substantial equity under our ATM programs and plan to continue to use these programs.

Operating Activities

Net cash provided by operating activities during the ninethree months ended September 30, 2017,March 31, 2018, was $34.8$12.6 million, as compared to net cash provided by operating activities of $29.8$10.5 million for the ninethree months ended September 30, 2016.March 31, 2017. This increase was primarily a result of an increase in rental receipts from acquisitions completed subsequent to September 30, 2016, a decrease in interest expense from refinanced and repaid mortgages during the previous 12 months, and a decrease in general and administrative fees from reducing our professional fees. These increases areMarch 31, 2017. This increase is partially offset by an increase in the base management fee, an increase in net property operating expenses, and a reduction in income earned due to the repayment of a mortgage interest receivable held through January 2016.expenses. The majority of cash from operating activities is generated from the rental payments and operating expense recoveries that we receive from our tenants. We utilize this cash to fund our property-level operating expenses and use the excess cash primarily for debt and interest payments on our mortgage notes payable, interest payments on our Revolver and Term Loan, distributions to our stockholders, management fees to our Adviser, Administration fees to our Administrator and other entity-level operating expenses.


Investing Activities

Net cash used in investing activities during the ninethree months ended September 30, 2017,March 31, 2018, was $63.4$4.1 million, which primarily consisted of fiveone property acquisitions,acquisition, coupled with capital improvements performed at certain of our properties, partially offset by proceeds from the sale of four properties,two properties. Net cash provided by investing activities during the three months ended March 31, 2017, was $10.1 million, which primarily consisted of proceeds from the sale of one property, coupled with recovering funds held in escrow from our lender for the mortgages we repaid.

During 2017, we have been executing our capital recycling program, whereby we opportunistically sell properties outside of our core markets, and use proceeds to repay outstanding debt, and fund mission critical property acquisitions located in our target secondary growth markets. During the nine months ended September 30, 2017, we sold four non-core properties and applied the proceeds towards outstanding debt. We will continue to sell non-core properties as reasonable disposition opportunities are available.properties.

Financing Activities

Net cash provided byused in financing activities during the ninethree months ended September 30, 2017,March 31, 2018, was $28.2 million, which primarily consisted of the issuance of $69.9 million of equity and mezzanine equity, coupled with the issuance of $51.2 million of new mortgage debt in connection with property acquisitions, partially offset by the repayment of $57.2 million of mortgage principal, coupled with distributions paid to common, senior common and preferred shareholders. Net cash used in financing activities for the nine months ended September 30, 2016, was $9.0$10.6 million, which primarily consisted of the repayment of $67.1$19.1 million of mortgage principal, coupled with distributions paid to common, senior common and preferred shareholders, partially offset by $56.0an increase in borrowings from our Revolver, the issuance of $1.6 million of equity and mezzanine equity and the issuance of $9.4 million of new mortgage debtdebt.

Credit Facility

InOn August 7 2013, we procured our Revolver with KeyBank (serving as a revolving lender, a letter of credit issuer and an administrative agent). In October 2015, we expanded our Revolver to $85.0 million, and entered into a Term Loan, whereby we added a $25.0 million, five-year Term Loan subject to the same leverage tiers as the Revolver, with the interest rate at each leverage tier being 5 basis points lower. We have the option to repay the Term Loan in full, or in part, at any time without penalty or premium prior to the maturity date. InOn October 27, 2017, we amended our existing Credit Facility. The Term Loan component of the Credit Facility was increased from $25.0 million, to $75.0 million, with the Revolver commitment remaining at $85.0 million. The Term Loan has a new five-year term, with a maturity date of October 27, 2022, and the Revolver has a new four-year term, with a maturity date of October 27, 2021. The interest rate for the Credit Facility was reduced by 25 basis points at each of the leverage tiers. We entered into interest rate cap agreements on the amended Term Loan, which cap LIBOR at 2.75%. We used the net proceeds of the amended Credit Facility to repay all previously existing borrowings under the Revolver. We incurred fees of approximately $0.9 million in connection with the Credit Facility amendment. The bank syndicate is now comprised of KeyBank, Fifth Third Bank, US Bank National Association and The Huntington National Bank.

As of September 30, 2017,March 31, 2018, there was $69.2$107.7 million outstanding under our Credit Facility at a weighted average interest rate of approximately 3.22%3.60% and $1.0 million outstanding under letters of credit at a weighted average interest rate of 2.00%1.75%. As of October 31, 2017,May 1, 2018, the maximum additional amount we could draw under the Revolver and Term Loan was $29.4$48.4 million. We were in compliance with all covenants under the Credit Facility as of September 30, 2017.March 31, 2018.

(2)Interest on debt obligations includes estimated interest on borrowings under our Revolver and Term Loan and mortgage notes payable. The balance and interest rate on our Revolver and Term Loan is variable; thus, the interest payment obligation calculated for purposes of this table was based upon rates and balances as of September 30, 2017.March 31, 2018.
(3)Operating lease obligations represent the ground lease payments due on our four of our properties.
(4)Purchase obligations consist of tenant and capital improvements at five of our properties. These items were recognized on our balance sheet as of September 30, 2017.

Off-Balance Sheet Arrangements

We did not have any material off-balance sheet arrangements as of September 30, 2017.March 31, 2018.

Funds from Operations

The National Association of Real Estate Investment Trusts or NAREIT,("NAREIT"), developed FFOFunds from Operations ("FFO") as a relevant non-GAAP supplemental measure of operating performance of an equity REIT to recognize that income-producing real estate historically has not depreciated on the same basis determined under GAAP. FFO, as defined by NAREIT, is net income (computed in accordance with GAAP), excluding gains or losses from sales of property and impairment losses on property, plus depreciation and amortization of real estate assets, and after adjustments for unconsolidated partnerships and joint ventures.

FFO does not represent cash flows from operating activities in accordance with GAAP, which, unlike FFO, generally reflects all cash effects of transactions and other events in the determination of net income. FFO should not be considered an alternative to net income as an indication of our performance or to cash flows from operations as a measure of liquidity or ability to make distributions. Comparison of FFO, using the NAREIT definition, to similarly titled measures for other REITs may not necessarily be meaningful due to possible differences in the application of the NAREIT definition used by such REITs.

FFO available to common stockholders is FFO adjusted to subtract distributions made to holders of preferred stock and senior common stock. We believe that net income available to common stockholders is the most directly comparable GAAP measure to FFO available to common stockholders.

Basic funds from operations per share or ("Basic FFO per share,share"), and diluted funds from operations per share or ("Diluted FFO per share,share"), is FFO available to common stockholders divided by the number of weighted average shares of common stock outstanding and FFO available to common stockholders divided by the number of weighted average shares of common stock outstanding on a diluted basis, respectively, during a period. We believe that FFO available to common stockholders, Basic FFO per share and Diluted FFO per share are useful to investors because they provide investors with a further context for evaluating our FFO results in the same manner that investors use net income and earnings per share or EPS,("EPS"), in evaluating net income available to common stockholders. In addition, because most REITs provide FFO available to common stockholders, Basic FFO and Diluted FFO per share information to the investment community, we believe these are useful supplemental measures when comparing us to other REITs. We believe that net income is the most directly comparable GAAP measure to FFO, Basic EPS is the most directly comparable GAAP measure to Basic FFO per share, and that Diluted EPS is the most directly comparable GAAP measure to Diluted FFO per share.


The following table provides a reconciliation of our FFO available to common stockholders for the three and nine months ended September 30,March 31, 2018 and 2017, and 2016, respectively, to the most directly comparable GAAP measure, net income available to common stockholders, and a computation of basic and diluted FFO per weighted average share of common stock:

Item 3.Quantitative and Qualitative Disclosures About Market Risk.

Market risk includes risks that arise from changes in interest rates, foreign currency exchange rates, commodity prices, equity prices and other market changes that affect market sensitive instruments. The primary risk that we believe we are and will be exposed to is interest rate risk. Certain of our leases contain escalations based on market indices, and the interest rate on our Credit Facility is variable. Although we seek to mitigate this risk by structuring such provisions of our loans and leases to contain a minimum interest rate or escalation rate, as applicable, these features do not eliminate this risk. To that end, we have entered into derivative contracts to cap interest rates for our variable rate notes payable, and we have assumed anentered into interest rate swapswaps whereby we pay a fixed interest rate of 1.80% to our respective counterparty, and receive one month LIBOR in return. For details regarding our rate cap agreements and our interest rate swap agreementagreements see Note 76Mortgage Notes Payable and Credit Facility of the accompanying condensed consolidated financial statements.

To illustrate the potential impact of changes in interest rates on our net income for the ninethree months ended September 30, 2017,March 31, 2018, we have performed the following analysis, which assumes that our condensed consolidated balance sheet remainssheets remain constant and that no further actions beyond a minimum interest rate or escalation rate are taken to alter our existing interest rate sensitivity.

The following table summarizes the annual impact of a 1%, 2% and 3% increase, and a 1% decrease in the one month LIBOR as of September 30, 2017.March 31, 2018. As of September 30, 2017,March 31, 2018, our effective average LIBOR was 1.24%; thus,1.88%. Given that a 1%, 2% or 3% decrease couldin LIBOR would result in a negative rate, the impact of these fluctuations are not occurpresented below (dollars in thousands).

As of September 30, 2017,March 31, 2018, the fair value of our mortgage debt outstanding was $461.8$440.5 million. Interest rate fluctuations may affect the fair value of our debt instruments. If interest rates on our debt instruments, using rates at September 30, 2017,March 31, 2018, had been one percentage point higher or lower, the fair value of those debt instruments on that date would have decreased or increased by $19.7$17.9 million and $21.2$19.2 million, respectively.

The amount outstanding under the Credit Facility approximates fair value as of September 30, 2017.March 31, 2018.

In the future, we may be exposed to additional effects of interest rate changes, primarily as a result of our Revolver, Term Loan or long-term mortgage debt, which we use to maintain liquidity and fund expansion of our real estate investment portfolio and operations. Our interest rate risk management objectives are to limit the impact of interest rate changes on earnings and cash flows and to lower overall borrowing costs. To achieve these objectives, we will borrow primarily at fixed rates or variable rates with the lowest margins available and, in some cases, with the ability to convert variable rates to fixed rates. We may also enter into derivative financial instruments such as interest rate swaps and caps in order to mitigate the interest rate risk on a related financial instrument. We will not enter into derivative or interest rate transactions for speculative purposes.

In addition to changes in interest rates, the value of our real estate is subject to fluctuations based on changes in local and regional economic conditions and changes in the creditworthiness of lessees and borrowers, all of which may affect our ability to refinance debt, if necessary.


Item 4.Controls and Procedures.

a) Evaluation of Disclosure Controls and Procedures

As of September 30, 2017,March 31, 2018, our management, including our chief executive officer and chief financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures. Based on that evaluation, the chief executive officer and chief financial officer, concluded that our disclosure controls and procedures were effective as of September 30, 2017March 31, 2018 in providing a reasonable level of assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in applicable SEC rules and forms, including providing a reasonable level of assurance that information required to be disclosed by us in such reports is accumulated and communicated to our management, including our chief executive officer and our chief financial officer, as appropriate to allow timely decisions regarding required disclosure. However, in evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated can provide only reasonable assurance of necessarily achieving the desired control objectives, and management was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

b) Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2017March 31, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
