Competition

        We face competition for the acquisition of properties from a variety of investors, including domestic and foreign corporations and real estate companies, financial institutions, insurance companies, pension funds, investment funds, other REITs and individuals, many of which have significant advantages over us, including a larger, more diverse group of properties and greater financial (including access to debt on more favorable terms) and other resources than we have.

Our Structure

        Nine employees, including Patrick J. Callan, Jr., our president and chief executive officer, Lawrence G. Ricketts, Jr., our executive vice president and chief operating officer, Justin Clair, a vice president, Benjamin Bolanos, a vice president, Karen Dunleavy, vice president-financial and fivefour other employees, devote all of their business time to us. Our other executive, administrative, legal, accounting and clerical personnel provide their services to us on a part-time basis, which services generally are provided pursuant to the compensation and services agreement described below.

        We entered into a compensation and services agreement with Majestic Property Management Corp. effective as of January 1, 2007. Majestic Property is wholly-ownedwholly owned by our vice chairman of the board and it provides compensation to certain of our executive officers. Pursuant to this agreement, we pay fees to Majestic Property and Majestic Property providesfor providing us with the services of all affiliated executive, administrative, legal, accounting, clerical and clericalproperty management personnel, that we use on a part time basis, as well as property managementacquisition, sale and lease consulting and brokerage services, property acquisition, salesconsulting services with respect to mortgage financings and leasing and mortgage brokerage services. The feesconstruction supervisory services (collectively, the "Services").The amount we pay Majestic Property are negotiatedfor the Services is approved each year by usthe compensation and/or audit committees of our board of directors, and Majestic Property in consultation with our audit and compensation committees, and are approved by these committees and ourthe independent directors.

        In 2017,2018, pursuant to the compensation and services agreement, we paid Majestic Property a fee of approximately $2.7 million plus $216,000 for our share of all direct office expenses, including rent, telephone, postage, computer services, supplies and internet usage. Included in the $2.7 million fee is $1,154,000$1.2 million for property management services—the feeamount for the property management services is based on 1.5% and 2.0% of the rental payments (including tenant reimbursements) actually received by us from net lease tenants and operating lease tenants, respectively. Property management fees areWe do not paid topay Majestic Property with respect to properties managed by third parties. Based on our portfolio of properties at December 31, 2017,2018, we estimate that the property management fee in 20182019 will be approximately $1,190,000.$1.2 million.

        We believe that the compensation and services agreement allows us to benefit from (i) access to, and from the services of, a group of senior executives with significant knowledge and experience in the real estate industry and our company, (ii) other individuals who perform services on our behalf, and (iii) general economies of scale. If not for this agreement, we believe that a company of our size would not have access to the skills and expertise of these executives at the cost that we have incurred and will incur in the future. For a description of the background of our management, please see the information under the heading "Executive Officers" in Part I of this Annual Report. See Note 12 to our consolidated financial statements for information regarding equity awards to individuals performing services on our behalf pursuant to the compensation and services agreement.

Item 1A.    Risk Factors.

        Set forth below is a discussion of certain risks affecting our business. The categorization of risks set forth below is meant to help you better understand the risks facing our business and is not intended to limit your consideration of the possible effects of these risks to the listed categories. Any adverse effects arising from the realization of any of the risks discussed, including our financial condition and results of operations, may, and likely will, adversely affect many aspects of our business. In addition to the other

information contained or incorporated by reference in this Form 10-K, readers should carefully consider the following risk factors:

Risks Related to Our Business

Approximately 40.2% of our 2018 contractual rental income is derived from tenants operating in the retail industry and the failure of those tenants to pay rent would significantly reduce our revenues.

        Approximately 40.2% of our 2018 contractual rental income is derived from retail tenants, including 9.0% from tenants engaged in retail furniture (i.e., Haverty Furniture accounts for 7.1% of

Table of Contents

2018 contractual rental income) and 3.6% from tenants engaged in office supply activities (i.e., Office Depot accounts for 3.6% of 2018 contractual rental income).

        Various factors could cause our retail tenants to close their locations, including difficult economic conditions and e-commerce competition. The failure of our retail tenants to meet their lease obligations, including rent payment obligations, due to these and other factors, may make it difficult for us to satisfy our operating and debt service requirements, make capital expenditures and pay dividends.

If we are unable to re-rent properties upon the expiration of our leases or if our tenants default or seek bankruptcy protection, our rental income will be reduced and we would incur additional costs.

        Substantially all of our rental income is derived from rent paid by our tenants. From 20182019 through 2020,2021, leases with respect to 33 tenants that account for 8.8%8.1% of our 20182019 contractual rental income, expire, and from 2022 through 2023, leases with respect to 45 tenants that account for 31.9% of our 2019 contractual rental income, expire. If our tenants, and in particular, our significant tenants, (i) do not renew their leases upon the expiration of same, (ii) default on their obligations or (iii) seek rent relief, lease renegotiation or other accommodations, our revenues could decline and, in certain cases, co-tenancy provisions may be triggered possibly allowing other tenants at the same property to reduce their rental payments or terminate their leases. At the same time, we would remain responsible for the payment of the mortgage obligations with respect to the related properties and would become responsible for the operating expenses related to these properties, including, among other things, real estate taxes, maintenance and insurance. We estimate that the aggregate carrying expense (including mortgage interest expense) in 2019 for properties and tenants facing significant challenges (i.e., our assisted living facility in Round Rock, Texas, a property tenanted by Kmart in Clemmons, North Carolina, and a vacant retail property in Crystal Lake, Illinois), is approximately $1.7 million, but may exceed such sum. In addition, we may incur expenses in enforcing our rights as landlord. Even if we find replacement tenants (which we may be constrained in accomplishing with respect to our assisted living facility in Round Rock, Texas by competing facilities in such market and regulatory requirements mandating that such facilities be operated by specially licensed operators) or renegotiatere-negotiate leases with current tenants, the terms of the new or renegotiated leases, including the cost of required renovations or concessions to tenants, or the expense of the reconfiguration of a tenant's space, may be less favorable than current lease terms and could reduce the amount of cash available to meet expenses and pay dividends. If tenants facing financial difficulties default on their obligation to pay rent or do not renew their leases at lease expiration, our results of operations and financial condition may be adversely affected. See "Item 7. Management's Discussion and Analysis of Financial Condition or Results of Operations—Other DevelopmentsChallenges Facing Certain Tenants and Properties."".

Approximately 22.9%Traditional retail tenants account for 36.6% of our 20182019 contractual rental income is derived from five tenants. The default, financial distress or failure of any of these tenants could significantly reduce our revenues.

        Haverty Furniture, LA Fitness, Northern Tool, Office Depot and Ferguson Enterprises account for approximately 7.1%, 4.5%, 4.2%, 3.6% and 3.5%, respectively, of our 2018 contractual rental income. The default, financial distress or bankruptcy of any of these tenants could cause interruptions in the receipt of, or the loss of, a significant amount of rental income and would require us to pay operating expenses (including real estate taxes) currently paid by the tenant. This could also result in the vacancy of the property or properties occupied by the defaulting tenant, which would significantly reduce our rental revenues and net income until the re-rental of the property or properties, and could decrease the ultimate sale value of the property.

Competitioncompetition that traditional retailsuch tenants face from e-commerce retail sales could adversely affect our business.

        Approximately 36.6% of our 2019 contractual rental income is derived from retail tenants, including 8.8% from tenants engaged in retail furniture (i.e., Haverty Furniture accounts for 7.0% of 2019 contractual rental income) and 3.1% from tenants engaged in office supply activities (i.e., Office Depot accounts for 3.1% of 2019 contractual rental income). Our retail tenants face increasing competition from e-commerce retailers. These retailers may be able to provide customers with better pricing and the ease and comfort of shopping from their home or office. E-commerce sales have been obtaining an increasing percentage of retail sales over the past few years and this trend is expected to continue. The continued growth of e-commerce sales could decrease the need for traditional retail outlets and reduce retailers' space and property requirements. This could adversely impact our ability to rent space at our retail properties and increase competition for retail tenants thereby reducing the rent we would receive at these properties and adversely affect our results of operations and financial condition.

Table of Contents

Approximately 22.7% of our 2019 contractual rental income is derived from five tenants. The default, financial distress or failure of any of these tenants could significantly reduce our revenues.

        Haverty Furniture, LA Fitness, Northern Tool, L-3 Technologies and Ferguson Enterprises account for approximately 7.0%, 4.5%, 4.1%, 3.8% and 3.4%, respectively, of our 2019 contractual rental income. The default, financial distress or bankruptcy of any of these tenants could cause interruptions in the receipt of, or the loss of, a significant amount of rental income and would require us to pay operating expenses (including real estate taxes) currently paid by the tenant. This could also result in the vacancy of the property or properties occupied by the defaulting tenant, which would significantly reduce our rental revenues and net income until the re-rental of the property or properties, and could decrease the ultimate sale value of the property.

If we are unable to refinance our mortgage loans at maturity, we may be forced to sell properties at disadvantageous terms, which would result in the loss of revenues and in a decline in the value of our portfolio.

        We had, as of December 31, 2017, $392.52018, $423.1 million in mortgage debt outstanding, all of which is non-recourse (subject to standard carve-outs) and our ratio of mortgage debt to total assets was 53.3%54.2%. OurAs of December 31, 2018, our Manahawkin, New Jersey joint venturesventure had $35.0$23.9 million in total mortgage indebtedness (all of which is non-recourse, subject to standard carve-outs). The risks associated with our mortgage debt and(including the Manahawkin, New Jersey mortgage debt of our joint ventures includedebt), includes the risk that cash flow from properties securing the indebtedness and our available cash and cash equivalents will be insufficient to meet required payments of principal and interest.

        Generally, only a portion of the principal of our mortgage indebtedness will be repaid prior to or at maturity and we do not plan to retain sufficient cash to repay such indebtedness at maturity. Accordingly, to meet these obligations if they cannot be refinanced at maturity, we will have to use funds available under our credit facility, if any, and our available cash and cash equivalents to pay our mortgage debt or seek to raise funds through the financing of unencumbered properties, sale of properties or the issuance of additional equity. From 20182019 through 2022,2023, approximately $111.4$139.3 million of our mortgage debt matures—specifically, $20.4 million in 2018, $14.6$16.0 million in 2019, $11.9$13.8 million in 2020, $20.7$22.7 million in 2021, and $43.8$45.8 million in 2022. With respect to our joint ventures, approximately $14.2 million of mortgage debt matures from 2018 through 2022—specifically, $4.32022 and $41.0 million in 2018, $877,000 in 2019, $911,000 in 2020, $948,000 in 2021, and $7.2 million in 2022.2023. If we (or our joint ventures) are unsuccessful in refinancing or extending existing mortgage indebtedness or financing unencumbered properties, selling properties on favorable terms or raising additional equity, our cash flow (or the cash flow of a joint venture) will not be sufficient to repay all maturing mortgage debt when payments become due, and we (or athis joint venture) may be forced to dispose of properties on disadvantageous terms or convey properties secured by mortgages to the mortgagees, which would lower our revenues and the value of our portfolio.

        We may find that the value of a property could be less than the mortgage secured by such property. We may also have to decide whether we should refinance or pay off a mortgage on a property at which the mortgage matures prior to lease expiration and the tenant may not renew the lease. In these types of situations, after evaluating various factors, including among other things, the tenant's competitive position in the applicable submarket, our and our tenant's estimates of its prospects, consideration of alternative uses and opportunities to re-purpose or re-let the property, we may seek to renegotiate the terms of the mortgage, or to the extent that the loan is non-recourse and the terms of the mortgage cannot be satisfactorily renegotiated, forfeit the property by conveying it to the mortgagee and writing off our investment.

Declines in the value of our properties could result in impairment charges.

        If we are presented with indications of an impairment in the value of a particular property or group of properties, we will be required to evaluate any such property or properties. If we determine that any of our properties at which indicators of impairment exist have a fair market value below the net book

Table of Contents

value of such property, we will be required to recognize an impairment charge for the difference between the fair value and the book value during the quarter in which we make such determination; such impairment charges may then increase in subsequent quarters. This evaluation may lead us to write off any straight-line rent receivable and lease intangible balances recorded with respect to such property. In addition, we may incur losses from time to time if we dispose of properties for sales prices that are less than our book value.

Table of Contents

The concentration of our properties in certain states may make our revenues and the value of our portfolio vulnerable to adverse changes in local economic conditions.

        Many of the properties we own are located in the same or a limited number of geographic regions. Approximately 40.7%39.5% of our 20182019 contractual rental income will beis derived from properties located in five states—New York (8.7%), Texas (11.9%(8.6%), South Carolina (8.3%), New York (7.9%(8.4%), Pennsylvania (6.4%(7.8%) and North Carolina (6.2%). At December 31, 2017, approximately 43.1% of the net book value of our real estate investments was located in five states—Texas (11.3%), South Carolina (9.6%), Pennsylvania (9.3%), Tennessee (7.2%) and Maryland (5.7%(6.0%). As a result, a decline in the economic conditions in these states or in regions where our properties may be concentrated in the future, may have an adverse effect on the rental and occupancy rates for, and the property values of, these properties, which could lead to a reduction of our rental income and/or impairment charges.

Our portfolio of properties is concentrated in the industrial and retail real estate sectors, and our business would be adversely affected by an economic downturn in either of such sectors.

        Approximately 36.6% and 46.1% of our 2019 contractual rental income is derived from retail and industrial tenants, respectively, and we are vulnerable to economic declines that negatively impact these sectors of the economy, which could have an adverse effect on our results of operations, liquidity and financial condition.

If our credit facility is not renewed, interest rates increase or credit markets tighten, it may be more difficult for us to secure financing, which may limit our ability to finance or refinance our real estate properties, reduce the number of properties we can acquire, sell certain properties, and decrease our stock price.

        Our credit facility expires December 31, 2019. Among other things, we depend on the facility to allow us to acquire properties on an accelerated basis (thereby potentially making our offer to purchase a property more attractive than offers from competitors), without the delays that may be associated with traditional mortgage financing. We can provide no assurance that such facility will be renewed or that if renewed, that the terms thereof will not be less favorable that the terms of the current facility. If this facility is not renewed on terms acceptable to us, our liquidity and capital resource position may be adversely impacted.

        An increase in interest rates could reduce the amount investors are willing to pay for our common stock. Because REIT stocks are often perceived as high-yield investments, investors may perceive less relative benefit to owning REIT stocks as interest rates and the yield on government treasuries and other bonds increase.

        Increases in interest rates or reduced access to credit markets may make it difficult for us to obtain financing, refinance mortgage debt, limit the mortgage debt available on properties we wish to acquire and limit the properties we can acquire. Even in the event that we are able to secure mortgage debt on, or otherwise finance our real estate properties, due to increased costs associated with securing financing and other factors beyond our control, we may be unable to refinance the entire outstanding loan balance or be subject to unfavorable terms (such as higher loan fees, interest rates and periodic payments) if we do refinance the loan balance. In addition, an increase in interest rates could decrease the amount third parties are willing to pay for our assets, thereby limiting our ability to reposition our portfolio promptly in response to changes in economic or other conditions.

Table of Contents

        While interest rates have been at historically low levels the past several years, they have recently been increasing and become increasingly volatile. AtDuring the three years ended December 29, 2017 and February 28,31, 2018, the interest rate on the 10-year treasury note was 2.40% and 2.87%, respectively.ranged from 1.37% to 3.24%. If we are required to refinance mortgage debt that matures over the next several years at higher interest rates than such mortgage debt currently bears, the funds available for dividends may be reduced. The following table sets forth, as of December 31, 2017,2018, the principal balance of the mortgage payments due at maturity on our properties and the weighted average interest rate thereon (dollars in thousands):

        We manage a substantial portion of our exposure to interest rate risk by accessing debt with staggered maturities, obtaining fixed rate mortgage debt and through the use of interest rate swap agreements. However, no amount of hedging activity can fully insulate us from the risks associated with changes in interest rates. Swap agreements involve risk, including that counterparties may fail to honor

Table of Contents

their obligations under these arrangements, and that these arrangements may cause us to pay higher interest rates on our debt obligations than would otherwise be the case. Failure to hedge effectively against interest rate risk could adversely affect our results of operations and financial condition.

If our borrowings increase, the risk of default on our repayment obligations and our debt service requirements will also increase.

        The terms of our revolving credit facility limit our ability to incur indebtedness, including limiting the total indebtedness that we may incur to an amount equal to 70% of the total value (as defined in the credit facility) of our properties. (At December 31, 2018, such total indebtedness was 49.4% of the total value of our properties). Increased leverage could result in increased risk of default on our payment obligations related to borrowings and in an increase in debt service requirements, which could reduce our net income and the amount of cash available to meet expenses and to pay dividends.

If a significant number of our tenants default or fail to renew expiring leases, or we take impairment charges against our properties, a breach of our revolving credit facility could occur.

        Our revolving credit facility includes covenants that require us to maintain certain financial ratios and comply with other requirements. If our tenants default under their leases with us or fail to renew expiring leases, generally accepted accounting principles may require us to recognize impairment charges against our properties, and our financial position could be adversely affected causing us to be in breach of the financial covenants contained in our credit facility.

        Failure to meet interest and other payment obligations under our revolving credit facility or a breach by us of the covenants to maintain the financial ratios would place us in default under our credit facility, and, if the banks called a default and required us to repay the full amount outstanding under the credit facility, we might be required to rapidly dispose of our properties, which could have an adverse impact on the amounts we receive on such disposition. If we are unable to dispose of our properties in a timely fashion to the satisfaction of the banks, the banks could foreclose on that portion of our collateral pledged to the banks, which could result in the disposition of our properties at below

Table of Contents

market values. The disposition of our properties at below our carrying value would adversely affect our net income, reduce our stockholders' equity and adversely affect our ability to pay dividends.

The re-development of a multi-tenant community shopping center located in Manahawkin, New Jersey owned by an unconsolidated joint venture may be unsuccessful or fail to meet our expectations.

        An unconsolidated joint venture in which we are a 50% partner is re-developing a multi-tenant community shopping center located in Manahawkin, New Jersey, and which we refer to as the Manahawkin Property. We anticipate that this project will be completed in stages through 2022 and that our share of the capital expenditures required in connection therewith may range from $10 million to $15 million. This re-development project may be unsuccessful or fail to meet our expectations due to a variety of risks and uncertainties including:

•

the joint venture's inability to obtain all necessary zoning and other required governmental permits and authorizations on a timely basis,



•

a decrease in cash flow from the property as the joint venture relocates tenants or choose not to renew leases at the property,



•

occupancy rates and rents at the re-developed property may not meet the expected levels and could be insufficient to make the property profitable,



•

the inability to complete the project on schedule, or at all, as a result of factors, many of which are beyond the joint venture's control, including weather, labor conditions and material shortages,



•

development and construction costs of the project may exceed the joint venture's estimates,



•

we or our joint venture partner may not have sufficient resources to fund the project, and



•

fluctuations in local and regional economic conditions due to the time lag between commencement and completion of the project.

        See"Item 2. Properties" and "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" for further information about the Manahawkin Property.

Certain of our net leases and our ground leases require us to pay property related expenses that are not the obligations of our tenants.

        Under the terms of substantially all of our net leases, in addition to satisfying their rent obligations, our tenants are responsible for the payment of real estate taxes, insurance and ordinary maintenance and repairs. However, under the provisions of certain net and ground leases, we are required to pay some expenses, such as the costs of environmental liabilities, roof and structural repairs, insurance premiums, certain non-structural repairs and maintenance. If our properties incur significant expenses that must be paid by us under the terms of our leases, our business, financial condition and results of operations will be adversely affected and the amount of cash available to meet expenses and pay dividends may be reduced.

Uninsured and underinsured losses may affect the revenues generated by, the value of, and the return from a property affected by a casualty or other claim.

        Most all of our tenants obtain, for our benefit, comprehensive insurance covering our properties in amounts that are intended to be sufficient to provide for the replacement of the improvements at each property. However, the amount of insurance coverage maintained for any property may be insufficient (i) to pay the full replacement cost of the improvements at the property following a casualty event or (ii) if coverage is provided pursuant to a blanket policy and the tenant's other properties are subject to

Table of Contents

insurance claims. In addition, the rent loss coverage under the policy may not extend for the full period

Table of Contents

of time that a tenant may be entitled to a rent abatement as a result of, or that may be required to complete restoration following, a casualty event In addition, there are certain types of losses, such as those arising from earthquakes, floods, hurricanes and terrorist attacks, that may be uninsurable or that may not be economically insurable. Changes in zoning, building codes and ordinances, environmental considerations and other factors also may make it impossible or impracticable for us to use insurance proceeds to replace damaged or destroyed improvements at a property. If restoration is not or cannot be completed to the extent, or within the period of time, specified in certain of our leases, the tenant may have the right to terminate the lease. If any of these or similar events occur, it may reduce our revenues, the value of, or our return from, an affected property.

Our revenues and the value of our portfolio are affected by a number of factors that affect investments in real estate generally.

        We are subject to the general risks of investing in real estate. These include adverse changes in economic conditions and local conditions such as changing demographics, retailing trends and traffic patterns, declines in the rental rates, changes in the supply and price of quality properties and the market supply and demand of competing properties, the impact of environmental laws, security concerns, prepayment penalties applicable under mortgage financings, changes in tax, zoning, building code, fire safety and other laws and regulations, the type of insurance coverage available in the market, and changes in the type, capacity and sophistication of building systems. Approximately 40.2% and 37.1% of our 2018 contractual rental income is from retail and industrial tenants, respectively, and we are vulnerable to economic declines that negatively impact these sectors of the economy, which could have an adverse effect on our results of operations, liquidity and financial condition.

Our revenues and the value of our portfolio are affected by a number of factors that affect investments in leased real estate generally.

        We are subject to the general risks of investing in leased real estate. These include the non-performance of lease obligations by tenants, leasehold improvements that will be costly or difficult to remove should it become necessary to re-rent the leased space for other uses, covenants in certain retail leases that limit the types of tenants to which available space can be rented (which may limit demand or reduce the rents realized on re-renting), rights of termination ofto terminate leases due to co-tenancy provisions(i.e., a tenant's right to reduce their rent or terminate their lease if certain key tenants vacate a property), events of casualty or condemnation affecting the leased space or the property or due to interruption of the tenant's quiet enjoyment of the leased premises, and obligations of a landlord to restore the leased premises or the property following events of casualty or condemnation.condemnation, adverse changes in economic conditions and local conditions (e.g., changing demographics, retailing trends and traffic patterns), declines in rental rates, changes in the supply and price of quality properties and the market supply and demand of competing properties, the impact of environmental laws, security concerns, prepayment penalties applicable under mortgage financings, changes in tax, zoning, building code, fire safety and other laws and regulations, the type of insurance coverage available, and changes in the type, capacity and sophistication of building systems. The occurrence of any of these events could adversely impact our results of operations, liquidity and financial condition.

Real estate investments are relatively illiquid and their values may decline.

        Real estate investments are relatively illiquid. Therefore, we will be limited in our ability to reconfigure our real estate portfolio in response to economic changes. We may encounter difficulty in disposing of properties when tenants vacate either at the expiration of the applicable lease or otherwise. If we decide to sell any of our properties, our ability to sell these properties and the prices we receive on their sale may be affected by many factors, including the number of potential buyers, the number of competing properties on the market and other market conditions, as well as whether the property is leased and if it is leased, the terms of the lease. As a result, we may be unable to sell our properties for an extended period of time without incurring a loss, which would adversely affect our results of operations, liquidity and financial condition.

Table of Contents

We have been, and in the future will be, subject to significant competition and we may not be able to compete successfully for investments.

        We have been, and in the future will be, subject to significant competition for attractive investment opportunities from other real estate investors, many of which have greater financial resources than us, including publicly-traded REITs, non-traded REITs, insurance companies, commercial and investment banking firms, private institutional funds, hedge funds, private equity funds and other investors. We may not be able to compete successfully for investments. If we pay higher prices for investments, our returns may be lower and the value of our assets may not increase or may decrease significantly below

the amount we paid for such assets. If such events occur, we may experience lower returns on our investments.

We cannot assure you of our ability to pay dividends in the future.

        We intend to pay quarterly dividends and to make distributions to our stockholders in amounts such that all or substantially all of our ordinary taxable income in each year is distributed. This, along with other factors, will enable us to qualify for the tax benefits accorded to a REIT under the Internal Revenue Code of 1986, as amended, which we refer to as the "Code".Code. We have not established a minimum dividend payment level and our ability to pay dividends may be adversely affected by the risk factors described in this Annual Report on Form 10-K. All distributions will be made at the discretion of our board of directors and will depend on our earnings (including taxable income), our financial condition, maintenance of our REIT status and such other factors as our board of directors may deem relevant from time to time.

If we reduce our dividend, the market value of our common stock may decline.

        The level of our common stock dividend is established by our board of directors from time to time based on a variety of factors, including our cash available for distribution, funds from operations, adjusted funds from operations and maintenance of our REIT status. Various factors could cause our board of directors to decrease our dividend level, including insufficient income to cover our dividends, tenant defaults or bankruptcies resulting in a material reduction in our funds from operations or a material loss resulting from an adverse change in the value of one or more of our properties. If our board of directors determines to reduce our common stock dividend, the market value of our common stock could be adversely affected.

Our current and future investments in joint ventures could be adversely affected by the lack of sole decision making authority, reliance on joint venture partners' financial condition or insurance coverage, disputes that may arise between our joint venture partners and us and our reliance on one significant joint venture partner.

        A number of properties in which we have an interest are owned through consolidated and unconsolidated joint ventures. We may continue to acquire properties through joint ventures and/or contribute some of our properties to joint ventures. Investments in joint ventures may, under certain circumstances, involve risks not present when a third party is not involved, including the possibility that joint venture partners might file for bankruptcy protection, fail to fund their share of required capital contributions or obtain insurance coverage pursuant to a blanket policy as a result of which claims with respect to other properties covered by such policy and in which we have no interest could reduce or eliminate the coverage available with respect to the joint venture properties. Further, joint venture partners may have conflicting business interests or goals, and as a result there is the potential risk of impasses on decisions, such as a sale and the timing thereof. Any disputes that may arise between joint venture partners and us may result in litigation or arbitration that would increase our expenses and prevent our officers and/or directors from focusing their time and effort on our business. Consequently, actions by or disputes with joint venture partners might result in subjecting properties owned by the joint venture to additional risk. With respect to our (i) consolidated joint ventures, we own, with two

joint venture partners and their respective affiliates, five properties that account for 5.1%5.4% of 20182019 contractual rental income, (and we own one property, of which our share of the annual base rent in 2018 is $1.4 million, with one of these joint venture partners through an unconsolidated joint venture), and (ii) unconsolidated joint ventures, we own, with onetwo joint venture partnerpartners and itstheir affiliates, threefour properties which account for our $326,000$1.5 million share of 20182019 base rent payable. We may be adversely affected if we are unable to maintain a satisfactory working relationship with these joint venture partners or if any of these partners becomes financially distressed.

Compliance with environmental regulations and associated costs could adversely affect our results of operations and liquidity.

        Under various federal, state and local laws, ordinances and regulations, an owner or operator of real property may be required to investigate and clean up hazardous or toxic substances or petroleum product releases at the property and may be held liable to a governmental entity or to third parties for property damage and for investigation and cleanup costs incurred in connection with contamination. The cost of investigation, remediation or removal of hazardous or toxic substances may be substantial, and the presence of such substances, or the failure to properly remediate a property, may adversely affect our ability to sell or rent the property or to borrow money using the property as collateral. In connection with our ownership, operation and management of real properties, we may be considered an owner or operator of the properties and, therefore, potentially liable for removal or remediation costs, as well as certain other related costs, including governmental fines and liability for injuries to persons and property, not only with respect to properties we own now or may acquire, but also with respect to properties we have owned in the past.

        We cannot provide any assurance that existing environmental studies with respect to any of our properties reveal all potential environmental liabilities, that any prior owner of a property did not create any material environmental condition not known to us, or that a material environmental condition does not otherwise exist, or may not exist in the future, as to any one or more of our properties. If a material environmental condition does in fact exist, or exists in the future, the remediation costs could have a material adverse impact upon our results of operations, liquidity and financial condition.

Compliance with the Americans with Disabilities Act could be costly.

        Under the Americans with Disabilities Act of 1990, all public accommodations must meet Federal requirements for access and use by disabled persons. A determination that our properties do not comply with the Americans with Disabilities Act could result in liability for both governmental fines and damages. If we are required to make unanticipated major modifications to any of our properties to comply with the Americans with Disabilities Act, which are determined not to be the responsibility of our tenants, we could incur unanticipated expenses that could have an adverse impact upon our results of operations, liquidity and financial condition.

Our senior management and other key personnel are critical to our business and our future success depends on our ability to retain them.

        We depend on the services of Matthew J. Gould, chairman of our board of directors, Fredric H. Gould, vice chairman of our board of directors, Patrick J. Callan, Jr., our president and chief executive officer, Lawrence G. Ricketts, Jr., our executive vice president and chief operating officer, David W. Kalish, our senior vice president and chief financial officer and Karen Dunleavy, our vice president—financial, and other members of our senior management to carry out our business and investment strategies. Only three of our most senior executive officers, Messrs. Callan and Ricketts, and Ms. Dunleavy, devote all of their business time to us. The remainder of our senior management provides services to us on a part-time, as-needed basis. The loss of the services of any of our senior management or other key

personnel, the inability or failure of the members of senior management providing services to us on a part-time basis to devote sufficient time or attention to our activities or our inability to recruit and retain qualified personnel in the future, could impair our ability to carry out our business and investment strategies.

Our transactions with affiliated entities involve conflicts of interest.

        From time to time we have entered into transactions with persons and entities affiliated with us and with certain of our officers and directors. Such transactions involve a potential conflict of interest, and entail a risk that we could have obtained more favorable terms if we had entered into such transaction with an unaffiliated third party. Our policy for transactions with affiliates is to have these transactions approved by our audit committee. We entered into a compensation and services agreement with Majestic Property effective as of January 1, 2007. Majestic Property is wholly-owned by the vice chairman of our board of directors and it provides compensation to certain of our part-time senior executive officers and other individuals performing services on our behalf. Pursuant to the compensation and services agreement, we pay an annual fee to Majestic Property which provides us with the services of all affiliated executive, administrative, legal, accounting and clerical personnel that we use on a part time basis, as well as property management services, property acquisition, sales and leasing and mortgage brokerage services. In 2017,2018, pursuant to the compensation and services agreement, we paid Majestic Property a fee of $2.7 million and an additional $216,000 for our share of all direct office expenses, including rent, telephone, postage, computer services, supplies, and internet usage. We also obtain our property insurance in conjunction with Gould Investors L.P., our affiliate, and in 2017,2018, reimbursed Gould Investors $790,000$912,000 for our share of the insurance premiums paid by Gould Investors. Gould Investors beneficially owns approximately 9.5%9.2% of our outstanding common stock and certain of our senior executive officers are also executive officers of the managing general partner of Gould Investors. See Note 1211 of our consolidated financial statements for information regarding equity awards to individuals performing services on our behalf pursuant to the compensation and services agreement.

The failure of any bank in which we deposit our funds could have an adverse impact on our financial condition.

        We have diversified our cash and cash equivalents between several banking institutions in an attempt to minimize exposure to any one of these entities. However, the Federal Deposit Insurance Corporation only insures accounts in amounts up to $250,000 per depositor per insured bank. We currently have cash and cash equivalents deposited in certain financial institutions significantly in excess of federally insured levels. If any of the banking institutions in which we have deposited funds ultimately fails, we may lose our deposits over $250,000. The loss of our deposits may have an adverse effect on our financial condition.

Breaches of information technology systems could materially harm our business and reputation.

        We collect and retain on information technology systems, certain financial, personal and other sensitive information provided by third parties, including tenants, vendors and employees. We also rely on information technology systems for the collection and distribution of funds. There can be no assurance that we will be able to prevent unauthorized access to sensitive information or the unauthorized distribution of funds. Any loss of this information or unauthorized distribution of funds as a result of a breach of information technology systems may result in loss of funds to which we are entitled, legal liability and costs (including damages and penalties), as well as damage to our reputation, that could materially and adversely affect our business.

We are dependent on third party software for our billing and financial reporting processes.

        We are dependent on third party software, and in particular Yardi's property management software, for generating tenant invoices and financial reports. If the software fails (including a failure resulting from such parties unwillingness or inability to maintain or upgrade the functionality of the software), our ability to bill tenants and prepare financial reports could be impaired which would adversely affect our business.

The potential phasing out of LIBOR after 2021 may affect our financial results.

        The authority regulating LIBOR has announced that it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. It is not possible to predict the effect of these changes or the establishment of alternative reference rates. Any changes in the manner in which LIBOR is calculated or the implementation of an alternative rate to succeed LIBOR, may result in a sudden or prolonged increase or decrease in the reported LIBOR rates. If that were to occur, the levels of interest payments we incur and interest payments we receive may change. In addition, although certain of our LIBOR based obligations and investments provide for alternative methods of calculating the interest rate if LIBOR is not reported, uncertainty as to the extent and manner of future changes may result in interest rates and/or payments that are higher than, lower than or that do not otherwise correlate over time with the interest rates and/or payments that would have been made on our obligations if LIBOR rate was available in its current form.
