Forward-Looking Statements

The following discussion should be read in conjunction with our audited consolidated financial statements and the notes thereto in this Annual Report on Form 10-K. 

This Annual Report on Form 10-K contains forward-looking statements within the meaning of the federal securities laws, including discussion and analysis of our financial condition, anticipated capital expenditures required to complete projects, amounts of anticipated cash distributions to our shareholders in the future and other matters. These forward-looking statements are not historical facts but reflect the intent, belief or current expectations of our management based on its knowledge and understanding of our business and industry. Forward-looking statements are typically identified by the use of terms such as “may,” “will,” “should,” “potential,” “predicts,” “anticipates,” “expects,” “intends,” “plans,” “believes,” “seeks,” “estimates” or the negative of such terms and variations of these words and similar expressions, although not all forward-looking statements include these words. These statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond our control, are difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements.

Forward-looking statements that were true at the time made may ultimately prove to be incorrect or false. You are cautioned not to place undue reliance on forward-looking statements, which reflect our management’s view only as of the date of this Annual Report on Form 10-K. We undertake no obligation to update or revise forward-looking statements to reflect changed assumptions, the occurrence of unanticipated events or changes to future operating results. Factors that could cause actual results to differ materially from any forward-looking statements made in this Annual Report on Form 10-K include:

• the imposition of federal taxes if we fail to qualify as a real estate investment trust (“REIT”) in any taxable year or forego an opportunity to ensure REIT status;

• uncertainties related to the national economy, the real estate industry in general and in our specific markets;

• legislative or regulatory changes, including changes to laws governing REITs;

• adverse economic or real estate developments or conditions in Texas or Arizona, Houston and Phoenix in particular;

• increases in interest rates, operating costs or general and administrative expenses;

• availability and terms of capital and financing to fund our operations, distributions to shareholders and to refinance our indebtedness as it matures;

• decreases in rental rates or increases in vacancy rates;

• litigation risks;

• lease-up risks, including leasing risks arising from exclusivity and consent provisions in leases with significant tenants;

• our inability to renew tenants or obtain new tenants upon the expiration of existing leases;

• our inability to generate sufficient cash flows due to market conditions, competition, uninsured losses, changes in tax or other applicable laws;

• the need to fund tenant improvements or other capital expenditures out of operating cash flow; and

• the risk that we are unable to raise capital for working capital, acquisitions or other uses on attractive terms or at all.

The forward-looking statements should be read in light of these factors and the factors identified in the “Risk Factors” section of this Annual Report on Form 10-K.

PART I

Item 1.  Business.

General

We are a Maryland REIT engaged in owning and operating commercial properties in culturally diverse markets in major metropolitan areas. Founded in 1998, we changed our state of organization from Texas to Maryland in December 2003.  We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”).

We are internally managed and, as of December 31, 2019, we wholly-owned a real estate portfolio of 58 properties that meet our Community Centered Property^® strategy containing approximately 5.0 million square feet of gross leasable area (“GLA”), located in Texas, Arizona and Illinois.  Our consolidated property portfolio has a gross book value of approximately $1.1 billion and book equity, including noncontrolling interests, of approximately $353 million as of December 31, 2019.

Further, as of December 31, 2019, we, through our equity-method investment in Pillarstone Capital REIT Operating Partnership LP (“Pillarstone” or “Pillarstone OP”), owned a majority interest in 8 properties that do not meet our Community Centered Property^® strategy containing approximately 0.9 million square feet of GLA (the “Pillarstone Properties”). We own 81.4% of the total outstanding units of Pillarstone OP, which we account for using the equity method. We also manage the day-to-day operations of Pillarstone OP. In this Annual Report on Form 10-K, unless otherwise indicated, we do not include the Pillarstone Properties when we refer to our properties.

Our common shares of beneficial interest, par value $0.001 per share, are traded on the New York Stock Exchange (the “NYSE”) under the ticker symbol “WSR.”  Our offices are located at 2600 South Gessner, Suite 500, Houston, Texas 77063.  Our telephone number is (713) 827-9595 and we maintain a website at www.whitestonereit.com. The contents of our website are not incorporated into this filing.

Our Strategy

In October 2006, our current management team joined the Company and adopted a strategic plan to acquire, redevelop, own and operate Community Centered Properties^®. We define Community Centered Properties^® as visibly located properties in established or developing culturally diverse neighborhoods in our target markets. We market, lease and manage our centers to match tenants with the shared needs of the surrounding neighborhood. Those needs may include specialty retail, grocery, restaurants and medical, educational and financial services. Our goal is for each property to become a Whitestone-branded retail community that serves a neighboring five-mile radius around our property. We employ and develop a diverse group of associates who understand the needs of our multicultural communities and tenants.

Our primary business objective is to increase shareholder value by acquiring, owning and operating Community Centered Properties^®. The key elements of our strategy include:

• Strategically Acquiring Properties.

◦ Seeking High Growth Markets. We seek to strategically acquire commercial properties in high-growth markets. Our acquisition targets are located in densely populated, culturally diverse neighborhoods, primarily in and around Austin, Chicago, Dallas-Fort Worth, Houston, Phoenix and San Antonio.

◦ Diversifying Geographically. Our current portfolio is concentrated in Houston and Phoenix. As of December 31, 2019, we wholly-owned 58 commercial properties, including 15 properties in Houston, eight properties in Dallas-Fort Worth, three properties in San Antonio, four properties in Austin, 27 properties in the Scottsdale and Phoenix, Arizona metropolitan areas, and one property in Buffalo Grove, Illinois, a suburb of Chicago.

We believe that continued geographic diversification in markets where we have substantial knowledge and experience will help offset the economic risk from a single market concentration. We intend to continue to focus our expansion efforts on the Austin, Chicago, Dallas-Fort Worth, Houston, Phoenix and San Antonio markets. We believe our management infrastructure and capacity can accommodate substantial growth in those markets. We may also pursue opportunities in other regions that are consistent with our Community Centered Property^® strategy. Markets in which we have developed some knowledge and contacts include

1

Orlando, Florida and Denver, Colorado, both of which have economic, demographic and cultural profiles similar to our Arizona and Texas markets.

◦ Capitalizing on Availability of Reasonably Priced Acquisition Opportunities. We believe that currently and during the next several years there will continue to be excellent opportunities in our target markets to acquire quality properties at historically attractive prices. We intend to acquire assets in off-market transactions negotiated directly with owners or financial institutions holding foreclosed real estate and debt instruments that are either in default or on bank watch lists. Many of these assets may benefit from our Community Centered Property^® strategy and our management team’s experience in turning around distressed properties, portfolios and companies. We have extensive relationships with community banks, attorneys, title companies and others in the real estate industry with whom we regularly work to identify properties for potential acquisition.

• Redeveloping and Re-tenanting Existing Properties. We have substantial experience in repositioning underperforming properties and seek to add value through renovating and re-tenanting our properties to create Whitestone-branded Community Centered Properties^®. We seek to accomplish this by (1) stabilizing occupancy, with per property occupancy goals of 90% or higher; (2) adding leasable square footage to existing structures; (3) developing and building new leasable square footage on excess land; (4) upgrading and renovating existing structures; and (5) investing significant effort in recruiting tenants whose goods and services meet the needs of the surrounding neighborhood.

• Recycling Capital for Greater Returns. We seek to continually upgrade our portfolio by opportunistically selling properties that do not have the potential to meet our Community Centered Property^® strategy and redeploying the sale proceeds into properties that better fit our strategy. Some of our properties that we owned at the time our current management team assumed the management of the Company (the “non-core properties”) may not fit our Community Centered Property^® strategy, and we may look for opportunities to dispose of these properties as we continue to execute our strategy.

• Prudent Management of Capital Structure. Of our 58 properties, we currently have 50 properties that are unencumbered. We may seek to add mortgage indebtedness to existing and newly acquired unencumbered properties to provide additional capital for acquisitions. As a general policy, we intend to maintain a ratio of debt, net of cash, to undepreciated book value of real estate assets, including our proportional share of real estate from our unconsolidated real estate partnership, that is at or less than 60%. As of December 31, 2019, our ratio of debt, net of cash, to undepreciated book value of real estate assets was 56%.

• Investing in People. We believe that our people are the heart of our culture, philosophy and strategy. We continually focus on developing associates who are self-disciplined and motivated and display, at all times, a high degree of character and competence. We provide them with equity incentives to align their interests with those of our shareholders.

Our Structure

Substantially all of our business is conducted through Whitestone REIT Operating Partnership, L.P., a Delaware limited partnership organized in 1998 (the “Operating Partnership”).  We are the sole general partner of the Operating Partnership.  As of December 31, 2019, we owned a 97.9% interest in the Operating Partnership.

As of December 31, 2019, we wholly-owned a real estate portfolio consisting of 58 properties located in three states.  The aggregate occupancy rate of our portfolio was 90% based on GLA as of December 31, 2019.

We are hands-on owners who directly manage the operations and leasing of our properties.  Substantially all of our revenues consist of base rents received under varying term leases.  For the year ended December 31, 2019, our total revenues were approximately $119.3 million.  

Additionally, we, through our equity-method investment in Pillarstone, owned a majority interest in eight properties located in Dallas and Houston, Texas. The aggregate occupancy rate of the Pillarstone properties was 75% based on GLA as of December 31, 2019.

2

Our largest property, BLVD Place (“BLVD”), a retail community purchased on May 26, 2017 and located in Houston, Texas, accounted for 13.4% of our total revenues for the year ended December 31, 2019. BLVD also accounted for 16.9% of our consolidated real estate assets, net of accumulated depreciation, as of the year ended December 31, 2019. Of our 58 properties, 15 and 27 are located in the Houston, Texas and Phoenix, Arizona metropolitan areas, respectively.

Economic Environment

Low interest rates and desire for higher yielding investments with moderate risk has resulted in lower capitalization rates and higher prices for commercial real estate acquisitions. Each of these factors could negatively impact the value of public real estate companies, including ours.  However, the majority of our retail properties are located in densely populated metropolitan areas and are occupied by tenants that generally provide basic necessity-type items and services which have tended to be less affected by economic changes.  Furthermore, a substantial portion of our portfolio is in metropolitan areas in Texas that have been impacted less by the economic slowdown compared to other metropolitan areas.

Competition

All of our properties are located in areas that include competing properties.  The amount of competition in a particular area could impact our ability to acquire additional real estate, sell current real estate, lease space and the amount of rent we are able to charge.  We may be competing with owners, developers and operators, including, but not limited to, real estate investors, other REITs, insurance companies and pension funds.

Should we decide to dispose of a property, we may compete with third-party sellers of similar types of commercial properties for suitable purchasers, which may result in our receiving lower net proceeds from a sale or in our not being able to dispose of such property at a time of our choosing due to the lack of an acceptable return. In operating and managing our properties, we compete for tenants based upon a number of factors including, but not limited to, location, rental rates, security, flexibility, expertise to design space to meet prospective tenants’ needs and the manner in which the property is operated, maintained and marketed. We may be required to provide rent concessions, incur charges for tenant improvements and other inducements, or we may not be able to timely lease vacant space, all of which could adversely impact our results of operations.

Many of our competitors have greater financial and other resources than us and also may have more operating experience. Generally, there are other neighborhood and community retail centers within relatively close proximity to each of our properties. There is, however, no dominant competitor in the Austin, Chicago, Dallas-Fort Worth, Houston, Phoenix and San Antonio metropolitan areas. Our retail tenants also face increasing competition from outlet malls, internet retailers, catalog companies, direct mail and telemarketing.

Compliance with Governmental Regulations

Under various federal and state environmental laws and regulations, as an owner or operator of real estate, we may be required to investigate and clean up certain hazardous or toxic substances, asbestos-containing materials, or petroleum product releases at our properties. We may also be held liable to a governmental entity or to third parties for property damage and for investigation and cleanup costs incurred by those parties in connection with any such contamination. In addition, some environmental laws create a lien on a contaminated site in favor of the government for damages and costs the government incurs in connection with contamination on the site. The presence of contamination or the failure to remediate contamination at any of our properties may adversely affect our ability to sell or lease the properties or to borrow using the properties as collateral. We could also be liable under common law to third parties for damages and injuries resulting from environmental contamination coming from our properties.

We will not purchase any property unless we are generally satisfied with the environmental status of the property. We typically obtain a Phase I environmental site assessment for each new acquisition, which includes a visual survey of the building and the property in an attempt to identify areas of potential environmental concerns, visually observing neighboring properties to assess surface conditions or activities that may have an adverse environmental impact on the property, and contacting local governmental agency personnel and performing a regulatory agency file search in an attempt to determine any known environmental concerns in the immediate vicinity of the property. A Phase I environmental site assessment does not include any sampling or testing of soil, groundwater or building materials from the property.

3

We believe that our properties are in compliance in all material respects with all applicable federal, state and local laws and regulations regarding the handling, discharge and emission of hazardous or toxic substances. Because release of chlorinated solvents can occur as a result of dry cleaning operations, we participate in the Texas Commission on Environmental Quality Dry Cleaner Remediation Program (“DCRP”) with respect to four of our properties that currently or previously had a dry cleaning facility as a tenant. The DCRP administers the Dry Cleaning Remediation fund to assist with remediation of contamination caused by dry cleaning solvents.

We have not been notified by any governmental authority, and are not otherwise aware of any material noncompliance, liability or claim relating to hazardous or toxic substances in connection with any of our present or former properties. Nevertheless, it is possible that the environmental assessments conducted thus far and currently available to us do not reveal all potential environmental liabilities. It is also possible that subsequent investigations will identify material contamination or other adverse conditions, that adverse environmental conditions have arisen subsequent to the performance of the environmental assessments, or that there are material environmental liabilities of which management is unaware.

Under the Americans with Disabilities Act (“ADA”), all places of public accommodation are required to meet certain federal requirements related to access and use by disabled persons. Our properties must comply with the ADA to the extent that they are considered “public accommodations” as defined by the ADA. The ADA may require removal of structural barriers to access by persons with disabilities in public areas of our properties where such removal is readily achievable. We believe that our properties are in substantial compliance with the ADA and that we will not be required to make substantial capital expenditures to address the requirements of the ADA. In addition, we will continue to assess our compliance with the ADA and to make alterations to our properties as required.

Employees

As of December 31, 2019, we had 108 full-time employees.

Item 1A.  Risk Factors.

In addition to the other information contained in this Annual Report on Form 10-K, the following risk factors should be considered carefully in evaluating our business.  Our business, financial condition, results of operations or the trading price of our common shares could be materially adversely affected by any of these risks.  Please note that additional risks not presently known to us or which we currently consider immaterial may also impair our business and operations.

Risks Associated with Real Estate

Market disruptions may significantly and adversely affect our financial condition and results of operations.

World financial markets have, from time to time, experienced significant disruption. While many U.S. real estate markets have generally stabilized since the pervasive and fundamental disruptions associated with the last recession, which resulted in increased unemployment, weakening of tenant financial condition, large-scale business failures and tight credit markets, the financial markets have been volatile recently, and oil prices have declined dramatically over the past year. Our results of operations may be sensitive to changes in overall economic conditions that impact tenants of our properties or tenant leasing practices. Adverse economic conditions affecting tenant income, such as employment levels, business conditions, interest rates, tax rates, fuel and energy costs and other matters, could reduce overall tenant leasing or cause tenants to shift their leasing practices. In addition, periods of economic slowdown or recession, rising interest rates or declining demand for real estate, or the public perception that any of these events may occur, could result in a general decline in rents or an increased incidence of defaults under existing leases. In addition, financial markets may again experience significant and prolonged disruption, including as a result of unanticipated events, or as a result of recent uncertainty regarding legislative and regulatory shifts relating to, among other things, taxation and trade, which we believe is likely to continue as a result of, among other things, the upcoming U.S. election, and which could adversely affect our tenants and our business in general. For example, a general reduction in consumer spending and the level of tenant leasing could adversely affect our ability to maintain our current tenants and gain new tenants, affecting our growth and profitability. Accordingly, if financial and macroeconomic conditions deteriorate, or if financial markets experience significant disruption, it could have a significant adverse effect on our cash flows, profitability, results of operations and the trading price of our common shares.

Real estate property investments are illiquid due to a variety of factors and therefore we may not be able to dispose of properties when appropriate or on favorable terms.

Our strategy includes opportunistically selling properties that do not have the potential to meet our Community Centered Property^® strategy. However, real estate property investments generally cannot be disposed of quickly. In addition, the Code imposes certain restrictions on the ability of a REIT to dispose of properties that are not applicable to other types of real estate companies. Therefore, we may not be able to vary our portfolio in response to economic or other conditions promptly or on favorable terms, which could cause us to incur extended losses, reduce our cash flows and adversely affect distributions to shareholders.

We cannot predict whether we will be able to sell any property for the price or on the terms set by us or whether any price or other terms offered by a prospective purchaser would be acceptable to us. We also cannot predict the length of time needed to find a willing purchaser and to close the sale of a property. To the extent we are unable to sell any properties for our book value, we may be required to take a non-cash impairment charge or loss on the sale, either of which would reduce our net income.

We may be required to expend funds and time to correct defects or to make improvements before a property can be sold. We cannot assure you that we will have funds available to correct those defects or to make those improvements, which may impede our ability to sell a property. Further, we may agree to transfer restrictions that materially restrict us from selling a property for a period of time or impose other restrictions, such as a limitation on the amount of debt that can be placed or repaid on that property. These transfer restrictions could impede our ability to sell a property even if we deem it necessary or appropriate. These facts and any others that would further contribute to the illiquid character of real estate properties and impede our ability to respond to adverse changes in the performance of our properties may have a material adverse effect on our business, financial condition, results of operations, our ability to make distributions to our shareholders and the trading price of our common shares.

5

Our business is dependent upon our tenants successfully operating their businesses, and their failure to do so could have a material adverse effect on our ability to successfully and profitably operate our business.

We depend on our tenants to operate their businesses in a manner that generates revenues sufficient to allow them to meet their obligations to us, including their obligations to pay rent, maintain certain insurance coverage, pay real estate taxes and maintain the properties in a manner so as not to jeopardize their operating licenses or regulatory status. The ability of our tenants to fulfill their obligations under our leases may depend, in part, upon the overall profitability of their operations. Cash flow generated by the businesses of certain tenants may not be sufficient for such tenants to meet their obligations to us. Our financial position could be weakened and our ability to fulfill our obligations under our indebtedness and make distributions to our shareholders could be limited if a number of our tenants were unable to meet their obligations to us or failed to renew or extend their relationships with us as their lease terms expire, or if we were unable to lease or re-lease our properties on economically favorable terms.

Disruption in capital markets could adversely impact acquisition activities and pricing of real estate assets.

Volatility or other disruption in capital markets could adversely affect our access to or the cost of debt and equity capital, which could adversely affect our acquisition and other investment activities. Disruptions could include price volatility or decreased demand in equity markets, rising interest rates, tightening of underwriting standards by lenders and credit rating agencies and the significant inventory of unsold collateralized mortgage backed securities in the market. As a result, we may not be able to obtain favorable equity and debt financing in the future or at all. This may impair our ability to acquire properties at favorable returns or adversely affect our returns on investments in development and re-development projects, which may adversely affect our results of operations and distributions to shareholders. Furthermore, any turmoil in the capital markets could adversely impact the overall amount of capital available to invest in real estate, which may result in price or value decreases of real estate assets.

The value of investments in our common shares will be directly affected by general economic and regulatory factors we cannot control or predict.

Investments in real estate typically involve a high level of risk as the result of factors we cannot control or predict. One of the risks of investing in real estate is the possibility that our properties will not generate income sufficient to meet operating expenses or will generate income and capital appreciation, if any, at rates lower than those anticipated or available through investments in comparable real estate or other investments. The following factors may affect income from properties and yields from investments in properties and are generally outside of our control:

• conditions in financial markets;

• continuing deterioration of the brick-and-mortar retail industry;

• over-building in our markets;

• a reduction in rental income as the result of the inability to maintain occupancy levels;

• adverse changes in applicable tax, real estate, environmental or zoning laws;

• changes in general economic conditions or economic conditions in our markets;

• a taking of any of our properties by eminent domain;

• adverse local conditions (such as changes in real estate zoning laws that may reduce the desirability of real estate in the area);

• acts of God, such as hurricanes, earthquakes or floods, health and safety epidemics, such as the coranavirus outbreak and other uninsured losses;

• changes in supply of or demand for similar or competing properties in an area;

• changes in interest rates and availability of permanent debt capital, which may render the sale of a property difficult or unattractive; and

6

• periods of high interest rates, inflation or tight money supply.

Some or all of these factors may affect our properties, which could adversely affect our operations and ability to make distributions to shareholders.

All of our properties are subject to property taxes that may increase in the future, which could adversely affect our cash flow.

Our properties are subject to property taxes that may increase as property tax rates change and as the properties are assessed or reassessed by taxing authorities. As the owner of the properties we are ultimately responsible for payment of the taxes to the government. If property taxes increase, our tenants may be unable to make the required tax payments, ultimately requiring us to pay the taxes. In addition, we will generally be responsible for property taxes related to any vacant space in our properties.

Our assets may be subject to impairment charges.

We periodically evaluate our real estate investments and other assets for impairment indicators. The judgment regarding the existence of impairment indicators is based on factors such as market conditions, tenant performance and legal structure. If we determine that a significant impairment has occurred, we would be required to make an adjustment to the net carrying value of the asset, which could have a material adverse effect on our results of operations and funds from operations in the period in which the write-off occurs.

Compliance or failure to comply with laws requiring access to our properties by disabled persons could result in substantial cost.

The ADA and other federal, state and local laws generally require public accommodations be made accessible to disabled persons. Noncompliance with these laws could result in the imposition of fines by the government or the award of damages to private litigants. These laws may require us to modify our existing properties, which could require a significant investment of our cash resources that could otherwise be invested in more productive assets. These laws may also restrict renovations by requiring improved access to such buildings by disabled persons or may require us to add other structural features which increase our construction costs. Legislation or regulations adopted in the future may impose further obligations, restrictions or increased compliance costs on us with respect to improved access by disabled persons. We may incur unanticipated expenses that may be material to our financial condition or results of operations to comply with ADA and other federal, state and local laws, or in connection with lawsuits brought by private litigants.

We face intense competition, which may decrease, or prevent increases of, the occupancy and rental rates of our properties.

We compete with a number of developers, owners and operators of commercial real estate, many of whom own properties similar to ours in the same markets in which our properties are located. If our competitors offer space at rental rates below current market rates, or below the rental rates we currently charge our tenants, we may lose existing or potential tenants and we may be pressured to reduce our rental rates below those we currently charge or to offer more substantial rent abatements, tenant improvements, early termination rights or below-market renewal options in order to retain tenants when our tenants’ leases expire. This competitive environment could have a material adverse effect on our ability to lease our properties or any newly developed or acquired property, as well as on the rents charged.

Our acquisition strategy includes acquiring distressed commercial real estate, and we could face significant competition from other investors, REITs, hedge funds, private equity funds and other private real estate investors with greater financial resources and access to capital than us. Therefore, we may not be able to compete successfully for investments. In addition, the number of entities and the amount of purchasers competing for suitable investments may increase, all of which could result in competition for accretive acquisition opportunities and adversely affect our business plan and our ability to maintain our current dividend rate.

Risks Associated with Our Operations

Because a majority of our GLA is in the Houston and Phoenix metropolitan areas, an economic downturn in either area could adversely impact our operations and ability to make distributions to our shareholders.

The majority of our assets and revenues are currently derived from properties located in the Houston and Phoenix metropolitan areas. As of December 31, 2019, 25% and 48% of our GLA was located in Houston and Phoenix, respectively. Our results of operations are directly affected by our ability to attract financially sound commercial tenants. A significant economic downturn in the Houston or Phoenix metropolitan area may adversely impact our ability to locate and retain financially sound tenants, could have an adverse impact on our existing tenants’ revenues, costs and results of operations and may adversely affect their ability to meet their obligations to us. Likewise, we may be required to lower our rental rates to attract desirable tenants in such an environment. Consequently, because of the geographic concentration among our current assets, if either the Houston or Phoenix metropolitan area were to experience an economic downturn, our operations and ability to make distributions to our shareholders could be adversely impacted. In addition, a substantial component of the Houston economy is the oil and gas industry, and the current low prices of oil and natural gas could adversely affect companies in that industry and their employees, which could adversely affect the businesses of our Houston tenants.

We lease our properties to approximately 1,400 tenants and leases for approximately 10% to 20% of our GLA expire annually. Each year we face the risk of non-renewal of a significant percentage of our leases and the cost of re-leasing a significant amount of our available space, and our failure to meet leasing targets and control the cost of re-leasing our properties could adversely affect our rental revenue, operating expenses and results of operations.

Our Community Centered Property^® business model produces shorter term leases to smaller, non-national tenants, and substantially all of our revenues consist of base rents received under these leases. As of December 31, 2019, approximately 28% of the aggregate GLA of our properties is subject to leases that expire prior to December 31, 2021. We are subject to the risk that:

• tenants may choose not to, or may not have the financial resources to, renew these leases;

• we may experience significant costs associated with re-leasing a significant amount of our available space;

• we may experience difficulties and significant time lags re-leasing vacated space, which may cause us to fail to meet our occupancy and average base rent targets and experience increased costs of re-leasing; and

• the terms of any renewal or re-lease may be less favorable than the terms of the current leases.

We routinely seek to renew leases with our existing tenants prior to their expiration and typically begin discussions with tenants as early as 18 months prior to the expiration date of the existing lease. While our early renewal program and other leasing and marketing efforts provide early focus on expiring leases, and have generally been effective in producing lease renewals prior to expiration of the leases at rates comparable to or slightly in excess of the current rates, market conditions, including new supply of properties, and macroeconomic conditions in our markets and nationally could adversely impact our renewal rate and/or the rental rates we are able to negotiate. If any of these risks materialize, our rental revenue, operating expenses and results of operations could be adversely affected.

Many of our tenants are small businesses, which may have a higher risk of bankruptcy or insolvency.

Many of our tenants are small businesses that depend primarily on cash flows from their operations to pay their rent and without other resources could be at a higher risk of bankruptcy or insolvency than larger, national tenants. If tenants are unable to comply with the terms of our leases, we may be forced to modify the leases in ways that are unfavorable to us. Alternatively, the failure of a tenant to perform under a lease could require us to declare a default, repossess the space and find a suitable replacement tenant. There is no assurance that we would be able to lease the space on substantially equivalent or better terms than the prior lease, or at all, or successfully reposition the space for other uses. If one or more of our tenants files for bankruptcy relief, the Bankruptcy Code provides that a debtor has the option to assume or reject the unexpired lease within a certain period of time.

8

Any bankruptcy filing by or relating to one or more of our tenants could bar all efforts by us to collect pre-bankruptcy debts from that tenant or seize its property. A tenant bankruptcy could also delay our efforts to collect past due balances under the lease and could ultimately preclude collection of all or a portion of these sums. It is possible that we may recover substantially less than the full value of any unsecured claims we hold, if any. Furthermore, dealing with a tenant’s bankruptcy or other default may divert management’s attention and cause us to incur substantial legal and other costs. The bankruptcy or insolvency of a number of smaller tenants may have an adverse impact on our business, financial condition and results of operations, our ability to make distributions to our shareholders and the trading price of our common shares.

Uninsured losses relating to real property or excessively expensive premiums for insurance coverage may adversely affect our returns.

We attempt to adequately insure all of our properties to cover casualty losses. However, there are types of losses, generally catastrophic in nature, such as losses due to wars, acts of terrorism, earthquakes, floods, hurricanes, pollution or environmental matters, including as a result of climate change, which are uninsurable or not economically insurable, or may be insured subject to limitations, such as large deductibles or co-payments. Our current geographic concentration in the Houston metropolitan area potentially increases the risk of damage to our portfolio due to hurricanes. Insurance risks associated with potential terrorism acts could sharply increase the premiums we pay for coverage against property and casualty claims. In some instances, we may be required to provide other financial support, either through financial assurances or self-insurance, to cover potential losses. We cannot assure you that we will have adequate coverage for these losses. Also, to the extent we must pay unexpectedly large insurance premiums, we could suffer reduced earnings that would result in less cash to be distributed to shareholders.

Discovery of previously undetected environmentally hazardous conditions may adversely affect our operating results.

Under various federal, state and local environmental laws, ordinances and regulations, a current or previous owner or operator of real property may be liable for the cost of removal or remediation of hazardous or toxic substances on, under or in its property. The costs of removal or remediation could be substantial. These laws often impose liability whether or not the owner or operator knew of, or was responsible for, the presence of any hazardous or toxic substances. Environmental laws also may impose restrictions on the manner in which a property may be used or businesses may be operated, and these restrictions may require substantial expenditures. Environmental laws provide for sanctions in the event of noncompliance and may be enforced by governmental agencies or, in certain circumstances, by private parties. Certain environmental laws and common law principles could be used to impose liability for release of and exposure to hazardous substances, including asbestos containing materials into the air. In addition, third parties may seek recovery from owners or operators of real properties for personal injury or property damage associated with exposure to released hazardous substances. The cost of defending against claims of liability, of compliance with environmental regulatory requirements, of remediating any contaminated property, or of paying personal injury claims could materially adversely affect our business, assets or results of operations and, consequently, amounts available for distributions to our shareholders.

Certain of our properties currently include or have in the past included a dry cleaning facility as a tenant. See “Business - Compliance with Governmental Regulations.”

We may not be successful in consummating suitable acquisitions or investment opportunities, which may impede our growth and adversely affect the trading price of our common shares.

Our ability to expand through acquisitions is integral to our business strategy and requires us to consummate suitable acquisition or investment opportunities that meet our criteria and are compatible with our growth strategy. We may not be successful in consummating acquisitions or investments in properties that meet our acquisition criteria on satisfactory terms or at all. Failure to consummate acquisitions or investment opportunities, the failure of an acquired property to perform as expected, or the failure to integrate successfully any acquired properties without substantial expense, delay or other operational or financial problems, would slow our growth, which could in turn adversely affect the trading price of our common shares.

Our ability to acquire properties on favorable terms may be constrained by the following significant risks:

• competition from other real estate investors with significant capital, including other REITs and institutional investment funds;

• competition from other potential acquirers which may significantly increase the purchase price for a property we acquire, which could reduce our growth prospects;

9

• unsatisfactory results of our due diligence investigations or failure to meet other customary closing conditions;

• the failure of an acquired property to perform as expected; and

• failure to finance an acquisition on favorable terms or at all.

If any of these risks are realized, our business, financial condition and results of operations, our ability to make distributions to our shareholders and the trading price of our common shares may be materially and adversely affected.

Our success depends in part on our ability to execute our Community Centered Property^® strategy.

Our Community Centered Property^® strategy requires intensive management of a large number of small spaces and small tenant relationships. Our success depends in part upon our management’s ability to identify potential Community Centered Properties^® and find and maintain the appropriate tenants to create such a property. Lack of market acceptance of our Community Centered Property^® strategy or our inability to successfully attract and manage a large number of tenant relationships could adversely affect our occupancy rates, operating results and dividend rate.

Our business is significantly influenced by demand for retail space generally, and a decrease in such demand may have a greater adverse effect on our business than if we owned a more diversified real estate portfolio.

Because our portfolio of properties consists primarily of community and neighborhood shopping centers, a decrease in the demand for retail space, due to the economic factors discussed above or otherwise, may have a greater adverse effect on our business and financial condition than if we owned a more diversified real estate portfolio. The market for retail space has been, and could continue to be, adversely affected by weakness in the national, regional and local economies, the adverse financial conditions of some retailing companies, the ongoing consolidation in the retail sector, the excess amount of retail space in a number of markets, health and safety concerns such as the recent coronavirus outbreak and increasing online consumer purchases.

Loss of our key personnel, particularly our senior managers, could threaten our ability to execute our strategy and operate our business successfully.

We are dependent on the experience and knowledge of our key executive personnel, particularly certain of our senior managers who have been instrumental in setting our strategic direction, operating our business, identifying, recruiting and training key personnel and arranging necessary financing. Losing the services of any of these individuals could adversely affect our business until qualified replacements could be found. We also believe that they could not quickly be replaced with managers of equal experience and capabilities and their successors may not be as effective.

Our systems may not be adequate to support our growth, and our failure to successfully oversee our portfolio of properties could adversely affect our results of operations.

We make no assurances that we will be able to adapt our portfolio management, administrative, accounting and operational systems, or hire and retain sufficient operational staff, to support our growth. Our failure to successfully oversee our current portfolio of properties or any future acquisitions or developments could have a material adverse effect on our results of operations and financial condition and our ability to make distributions.

We face risks relating to cybersecurity attacks, loss of confidential information and other business disruptions.

Our business is at risk from and may be impacted by cybersecurity attacks, including attempts to gain unauthorized access to our confidential data and other electronic security breaches. Such cyber-attacks can range from individual attempts to gain unauthorized access to our information technology systems to more sophisticated security threats. We have experienced cyber-attacks, and while to date none of these incidents have been material to our operations, we expect to continue to face such threats in the future. We employ a number of measures to prevent, detect and mitigate these threats, but there is no guarantee such efforts will be successful in preventing future cyber-attacks. In addition, cybersecurity incidents could compromise the confidential information of our tenants, employees and third party vendors that we collect in the ordinary course of our business. Laws and expectations relating to data protection and privacy vary by jurisdiction and continue to evolve, and we believe increased regulation in additional jurisdictions is likely to develop in the future. For example, the California Consumer Privacy Act (CCPA), that went into effect on January 1, 2020, requires covered companies to, among other things, provide new disclosures to California consumers, and afford such consumers new abilities to opt-out of certain sales of personal information. A cyber-attack or our ability or perceived inability to comply with regulations related to

10

cybersecurity and/or data protection and privacy could materially and adversely affect the efficiency of our business operations, which in turn could have a material adverse effect on our reputation, competitiveness and results of operations.

There can be no assurance that we will be able to pay or maintain cash distributions or that distributions will increase over time.

There are many factors that can affect the availability and timing of cash distributions to shareholders. Distributions are based upon our funds from operations, financial condition, cash flows and liquidity, debt service requirements, capital expenditure requirements for our properties and other matters our board of trustees may deem relevant from time to time. If we do not have sufficient cash available for distributions, we may need to fund the shortage out of working capital or borrow to provide funds for such distributions, which would reduce the amount of capital available for real estate investments and increase our future interest costs.

We can give no assurance that we will be able to continue to pay distributions or that distributions will increase over time. In addition, we can give no assurance that rents from our properties will increase, or that future acquisitions of real properties, mortgage loans or our investments in securities will increase our cash available for distributions to shareholders. Our actual results may differ significantly from the assumptions used by our board of trustees in establishing the distribution rate to shareholders. Our inability to make distributions, or to make distributions at expected levels, could result in a decrease in the trading price of our common shares.

Any weaknesses identified in our system of internal controls by us and our independent registered public accounting firm pursuant to Section 404 of the Sarbanes-Oxley Act of 2002 could have an adverse effect on our business.

Section 404 of the Sarbanes-Oxley Act of 2002 requires that public companies evaluate and report on their systems of internal control over financial reporting. In addition, our independent registered public accounting firm must report on management's evaluation of those controls. We may identify deficiencies in our system of internal controls over financial reporting that may require remediation. For example, we identified a material weakness in our internal controls over financial reporting as of December 31, 2018 that resulted in a material misstatement in our previously filed interim unaudited consolidated financial statements and concluded that our internal controls over financial reporting were not effective as of December 31, 2018 and that our disclosure controls and procedures were not effective as of March 31, 2018, June 30, 2018 and September 30, 2018. As a result, we restated our unaudited financial statements for the periods ended March 31, 2018, June 30, 2018 and September 30, 2018 and implemented a remediation plan for our internal controls over financial reporting and our disclosure controls and procedures. Although we believe we have adequately remediated our prior deficiencies, there can be no assurances that we will not identify future deficiencies and that any such future deficiencies may not be material weaknesses that would be required to be reported in future periods. Any deficiencies or material weaknesses could result in significant time and expense to remediate, which could have a material adverse effect on our financial condition, results of operations and ability to make distributions to our shareholders.

Expectations of the Company relating to environmental, social and governance factors may impose additional costs and expose us to new risks.

There is an increasing focus from certain investors, employees and other stakeholders concerning corporate social responsibility (“CSR”), specifically related to environmental, social and governance factors. Some investors may use these factors to guide their investment strategies and, in some cases, may choose not to invest in us if they believe our policies relating to CSR are inadequate. Third-party providers of CSR ratings and reports on companies have increased to meet growing investor demand for measurement of CSR performance. In addition, the criteria by which companies’ CSR practices are assessed may change, which could result in greater expectations of us and cause us to undertake costly initiatives to satisfy such new criteria. Alternatively, if we elect not to or are unable to satisfy such new criteria, investors may conclude that our policies with respect to CSR are inadequate. We may face reputational damage in the event that our CSR procedures or standards do not meet the standards set by various constituencies. Furthermore, if our competitors’ CSR performance is perceived to be greater than ours, potential or current investors may elect to invest with our competitors instead. In addition, in the event that we communicate certain initiatives and goals regarding environmental, social and governance matters, we could fail, or be perceived to fail, in our achievement of such initiatives or goals, or we could be criticized for the scope of such initiatives or goals. If we fail to satisfy the expectations of investors, employees and other stakeholders or our initiatives are not executed as planned, our reputation and financial results could be materially and adversely affected.

Risks Associated with Our Indebtedness and Financing

Current market conditions could adversely affect our ability to refinance existing indebtedness or obtain additional financing for growth on acceptable terms or at all, which could adversely affect our ability to grow, our interest cost and our results of operations.

The United States credit markets have experienced significant dislocations and liquidity disruptions, including the bankruptcy, insolvency or restructuring of certain financial institutions. These circumstances have materially impacted liquidity in the debt markets, making financing terms for borrowers less attractive, and in certain cases have resulted in the unavailability of various types of debt financing. Reductions in our available borrowing capacity, or inability to refinance our revolving credit facility when required or when business conditions warrant, could have a material adverse effect on our business, financial condition and results of operations. In addition, we mortgage many of our properties to secure payment of indebtedness. If we are not successful in refinancing our mortgage debt upon maturity, then the property could be foreclosed upon or transferred to the mortgagee, or we might be forced to dispose of some of our properties upon disadvantageous terms, with a consequent loss of income and asset value. A foreclosure or disadvantageous disposal on one or more of our properties could adversely affect our ability to grow, financial condition, interest cost, results of operations, cash flow and ability to make distributions to our shareholders.

 Furthermore, if prevailing interest rates or other factors at the time of refinancing result in higher interest rates upon refinancing, then the interest expense relating to that refinanced indebtedness would increase. Higher interest rates on newly incurred debt may negatively impact us as well. If interest rates increase, our interest costs and overall costs of capital will increase, which could adversely affect our transaction and development activity, financial condition, results of operation, cash flow, our ability to pay principal and interest on our debt and our ability to make distributions to our shareholders.

Our failure to hedge effectively against interest rate changes may adversely affect results of operations.

We currently have mortgages that bear interest at variable rates and we may incur additional variable rate debt in the future. Accordingly, increases in interest rates on variable rate debt would increase our interest expense, which could reduce net earnings and cash available for payment of our debt obligations and distributions to our shareholders.

We may seek to manage our exposure to interest rate volatility by using interest rate hedging arrangements, such as interest cap agreements and interest rate swap agreements. These agreements involve risks, such as the risk that counterparties may fail to honor their obligations under these arrangements, that these arrangements may not be effective in reducing our exposure to interest rate changes and that a court could rule that such an agreement is not legally enforceable. In the past, we have used derivative financial instruments to hedge interest rate risks related to our variable rate borrowings. We will not use derivatives for speculative or trading purposes and intend only to enter into contracts with major financial institutions based on their credit rating and other factors, but we may choose to change this practice in the future. As of December 31, 2019, we had fixed rate hedges on $274.3 million of our variable rate debt, including $265 million of our unsecured credit facility. We may enter into additional interest rate swap agreements for our variable rate debt not currently subject to hedges, which totaled $109.5 million as of December 31, 2019. Hedging may reduce the overall returns on our investments. Failure to hedge effectively against interest rate changes may materially and adversely affect our results of operations.

We currently have and may incur additional mortgage indebtedness and other borrowings, which may increase our business risks and may adversely affect our ability to make distributions to our shareholders.

If we determine it to be in our best interests, we may, in some instances, acquire real properties by using either existing financing or borrowing new funds. In addition, we may incur or increase our current mortgage debt to obtain funds to acquire additional properties. We may also borrow funds if necessary to satisfy the REIT distribution requirement described above, or otherwise as may be necessary or advisable to ensure that we maintain our qualification as a REIT for federal income tax purposes.

As of December 31, 2019, we had outstanding indebtedness, net of cash, of $630.4 million, including, through our Operating Partnership, $100.0 million aggregate principal amount of the Notes (as defined below) and $374.5 million drawn on the 2019 Facility (as defined below). As of December 31, 2019, our unused borrowing capacity under our 2019 Facility was $140.5 million. Obligations under the Notes and the 2019 Facility are guaranteed by the Company and certain subsidiary guarantors. Our current debt agreements, including the agreements governing the Notes and the 2019 Facility, contain, and any future debt agreements may contain, a number of restrictive and financial covenants that impose significant operating and financial restrictions on us. Such restrictive covenants may significantly limit our ability to:

12

• incur additional debt, including issuing guarantees;

• incur liens;

• make certain investments;

• sell or otherwise dispose of assets;

• make acquisitions;

• engage in mergers or consolidations or certain other “change of control” transactions;

• make distributions to our shareholders;

• engage in restructuring activities;

• engage in certain sale and leaseback transactions; and

• issue or repurchase common shares or other securities.

Such agreements may also require us to satisfy other requirements, including maintaining certain financial ratios and condition tests. Our ability to meet these requirements can be affected by events beyond our control, and we may be unable to meet them. To the extent we fail to meet any such requirements and are in default under our debt obligations, our financial condition may be materially adversely affected. Further, these restrictions may limit our ability to engage in activities that could otherwise benefit us. To the extent that we are unable to engage in activities that support the growth, profitability and competitiveness of our business, our results of operations may be materially adversely affected.

We may also incur mortgage debt on a particular property if we believe the property’s projected cash flow is sufficient to service the mortgage debt. As of December 31, 2019, we had approximately $171.4 million of mortgage debt secured by eight of our properties. If there is a shortfall in cash flow, however, the amount available for distributions to shareholders may be affected. In addition, incurring mortgage debt increases the risk of loss because defaults on such indebtedness may result in loss of property in foreclosure actions initiated by lenders. For tax purposes, a foreclosure of any of our properties would be treated as a sale of the property for a purchase price equal to the outstanding balance of the debt secured by the mortgage. If the outstanding balance of the debt secured by the mortgage exceeds our tax basis in the property, we would recognize taxable income on foreclosure, but would not receive any cash proceeds. We may give lenders full or partial guarantees for mortgage debt incurred by the entities that own our properties. When we give a guaranty on behalf of an entity that owns one of our properties, we will be responsible to the lender for satisfaction of the debt if it is not paid by that entity. If any mortgages contain cross-collateralization or cross-default provisions, there is a risk that more than one property may be affected by a default. If any of our properties are foreclosed upon due to a default, our ability to pay cash distributions to our shareholders may be adversely affected. For more discussion, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources.”

If we set aside insufficient working capital or are unable to secure funds for future tenant improvements, we may be required to defer necessary property improvements, which could adversely impact the quality of our properties and our results of operations.

When tenants do not renew their leases or otherwise vacate their space, it is possible that, in order to attract replacement tenants, we may be required to expend substantial funds for tenant improvements and refurbishments to the vacated space. If we have insufficient working capital reserves, we will have to obtain financing from other sources. Because most of our leases provide for tenant reimbursement of operating expenses, we have not established a permanent reserve for maintenance and repairs for our properties. However, to the extent that we have insufficient funds for such purposes, we may establish reserves for maintenance and repairs of our properties out of cash flow generated by operating properties or out of non-liquidating net sale proceeds. If these reserves or any reserves otherwise established are insufficient to meet our cash needs, we may have to obtain financing from either affiliated or unaffiliated sources to fund our cash requirements. We cannot assure you that sufficient financing will be available or, if available, will be available on economically feasible terms or on terms acceptable to us. Additional borrowing for working capital purposes will increase our interest expense, and therefore our financial condition and our ability to pay cash distributions to our shareholders may be adversely affected. In addition, we may be required to defer necessary improvements to our properties that may cause our properties to suffer from a greater risk of obsolescence or a decline in value, or a greater risk of decreased cash flow as a result of fewer potential tenants being attracted to our properties. If this happens, we may not be able to maintain projected rental rates for affected properties, and our results of operations may be negatively impacted.

13

We have in the past and may continue to structure acquisitions of property in exchange for limited partnership units in our Operating Partnership on terms that could limit our liquidity or our flexibility.

We have in the past and may continue to acquire properties by issuing limited partnership units in our Operating Partnership (“OP units”) in exchange for a property owner contributing property to the Operating Partnership. If we enter into such transactions, in order to induce the contributors of such properties to accept OP units, rather than cash, in exchange for their properties, it may be necessary for us to provide them with additional incentives. For instance, our Operating Partnership’s limited partnership agreement provides that any holder of OP units may redeem such units for cash, or, at our option, common shares on a one-for-one basis. We may, however, enter into additional contractual arrangements with contributors of property under which we would agree to redeem a contributor’s OP units for our common shares or cash, at the option of the contributor, at set times. If the contributor required us to redeem OP units for cash pursuant to such a provision, it would limit our liquidity and thus our ability to use cash to make other investments, satisfy other obligations or pay distributions. Moreover, if we were required to redeem OP units for cash at a time when we did not have sufficient cash to fund the redemption, we might be required to sell one or more properties to raise funds to satisfy this obligation. Furthermore, we might agree that if distributions the contributor received as a limited partner in our Operating Partnership did not provide the contributor with a defined return, then upon redemption of the contributor’s OP units, we would pay the contributor an additional amount necessary to achieve that return. Such a provision could further negatively impact our liquidity and flexibility. Finally, in order to allow a contributor of a property to defer taxable gain on the contribution of property to our Operating Partnership, we might agree not to sell a contributed property for a defined period of time or until the contributor redeemed the contributor’s OP units for cash or our common shares. Such an agreement would prevent us from selling those properties, even if market conditions made such a sale favorable to us.

We may issue preferred shares with a preference in distributions over our common shares, and our ability to issue preferred shares and additional common shares may deter or prevent a sale of our common shares in which you could profit.

Our declaration of trust authorizes our board of trustees to issue up to 400,000,000 common shares and 50,000,000 preferred shares. Our board of trustees may amend our declaration of trust from time to time to increase or decrease the aggregate number of shares or the number of any class or series that we have authority to issue. In addition, our board of trustees may classify or reclassify any unissued common shares or preferred shares and may set the preferences, rights and other terms of the classified or reclassified shares. The terms of preferred shares could include a preference in distributions senior to our common shares. If we authorize and issue preferred shares with a distribution preference senior to our common shares, payment of any distribution preferences of outstanding preferred shares would reduce the amount of funds available for the payment of distributions on our common shares. Further, holders of preferred shares are normally entitled to receive a preference payment in the event we liquidate, dissolve or wind up before any payment is made to our common shareholders, likely reducing the amount our common shareholders would otherwise receive upon such an occurrence. In addition, under certain circumstances, the issuance of preferred shares or a separate class or series of common shares may render more difficult or tend to discourage:

• a merger, tender offer or proxy contest;

• assumption of control by a holder of a large block of our shares; or

• removal of incumbent management.

Changes in how LIBOR is determined, or the potential replacement of LIBOR with an alternative reference rate, may adversely affect our interest expense.

A number of our current debt agreements, including our 2019 Facilities, have an interest rate tied to the London Interbank Offered Rate (“LIBOR”). On July 27, 2017, the United Kingdom Financial Conduct Authority, which regulates LIBOR, announced its intention to stop persuading or compelling banks to submit LIBOR quotations by the end of 2021. We cannot predict the impact of the potential phase out of LIBOR on our debt agreements and interest rates. While some of our current debt agreements provide procedures for determining an alternative base rate in the event that LIBOR is discontinued, not all do so. Regardless, there can be no assurances as to what alternative base rates may be and whether such base rate will be more or less favorable than LIBOR and any other unforeseen impacts of the potential discontinuation of LIBOR. The Company intends to monitor the developments with respect to the potential phasing out of LIBOR after 2021 and work with its lenders to ensure any transition away from LIBOR will have minimal impact on its financial condition, but can provide no assurances regarding the impact of the discontinuation of LIBOR on its financial condition or whether the discontinuation of LIBOR would have a material adverse effect on its results of operations.

Risks Associated with Income Tax Laws

If we fail to qualify as a REIT, our operations and distributions to shareholders would be adversely impacted.

We intend to continue to be organized and to operate so as to qualify as a REIT under the Code. A REIT generally is not taxed at the corporate level on income it currently distributes to its shareholders. Qualification as a REIT involves the application of highly technical and complex rules for which there are only limited judicial or administrative interpretations. The determination of various factual matters and circumstances not entirely within our control may affect our ability to continue to qualify as a REIT. In addition, new legislation, new regulations, administrative interpretations or court decisions could significantly change the tax laws, possibly with retroactive effect, with respect to qualification as a REIT or the federal income tax consequences of such qualification.

If we were to fail to qualify as a REIT in any taxable year:

• we would not be allowed to deduct our distributions to shareholders when computing our taxable income;

• we would be subject to federal income tax on our taxable income at regular corporate rates;

• we would be disqualified from being taxed as a REIT for the four taxable years following the year during which qualification was lost, unless entitled to relief under certain statutory provisions;

• our cash available for distributions to shareholders would be reduced; and

• we may be required to borrow additional funds or sell some of our assets in order to pay corporate tax obligations that we may incur as a result of our disqualification.

We may need to incur additional borrowings to meet the REIT minimum distribution requirement and to avoid excise tax.

In order to maintain our qualification as a REIT, we are required to distribute to our shareholders at least 90% of our annual real estate investment trust taxable income (excluding any net capital gain and before application of the dividends paid deduction). In addition, we are subject to a 4% nondeductible excise tax on the amount, if any, by which certain distributions paid by us with respect to any calendar year are less than the sum of (i) 85% of our ordinary income for that year, (ii) 95% of our net capital gain for that year and (iii) 100% of our undistributed taxable income from prior years. Although we intend to pay distributions to our shareholders in a manner that allows us to meet the 90% distribution requirement and avoid this 4% excise tax, we cannot assure you that we will always be able to do so.

Our income consists almost solely of our share of our Operating Partnership’s income, and the cash available for distribution by us to our shareholders consists of our share of cash distributions made by our Operating Partnership. Because we are the sole general partner of our Operating Partnership, our board of trustees determines the amount of any distributions made by our Operating Partnership. Our board of trustees may consider a number of factors in authorizing distributions, including:

• the amount of cash available for distribution;

• our Operating Partnership’s financial condition;

• our Operating Partnership’s capital expenditure requirements; and

• our annual distribution requirements necessary to maintain our qualification as a REIT.

Differences in timing between the actual receipt of income and actual payment of deductible expenses and the inclusion of income and deduction of expenses when determining our taxable income, as well as the effect of nondeductible capital expenditures and the creation of reserves or required debt amortization payments could require us to borrow funds on a short-term or long-term basis or make taxable distributions to our shareholders of our shares or debt securities to meet the REIT distribution requirement and to avoid the 4% excise tax described above. In these circumstances, we may need to borrow funds to avoid adverse tax consequences even if our management believes that the then prevailing market conditions generally are not favorable for borrowings or that borrowings would not be advisable in the absence of the tax consideration.

If our Operating Partnership were classified as a “publicly traded partnership” taxable as a corporation for federal income tax purposes under the Code, we would cease to qualify as a REIT and would suffer other adverse tax consequences.

We structured our Operating Partnership so that it would be classified as a partnership for federal income tax purposes. In this regard, the Code generally classifies “publicly traded partnerships” (as defined in Section 7704 of the Code) as associations taxable as corporations (rather than as partnerships), unless substantially all of their taxable income consists of specified types of passive income. In order to minimize the risk that the Code would classify our Operating Partnership as a “publicly traded partnership” for tax purposes, we placed certain restrictions on the transfer and/or redemption of partnership units in our Operating Partnership. If the Internal Revenue Service were to assert successfully that our Operating Partnership is a “publicly traded partnership,” and substantially all of its gross income did not consist of the specified types of passive income, the Code would treat our Operating Partnership as an association taxable as a corporation.

In such event, the character of our assets and items of gross income would change and would prevent us from continuing to qualify as a REIT. In addition, the imposition of a corporate tax on our Operating Partnership would reduce our amount of cash available for payment of distributions by us to our shareholders.

Complying with REIT requirements may cause us to forego otherwise attractive opportunities or liquidate otherwise attractive investments.

To qualify as a REIT for federal income tax purposes, we must continually satisfy tests concerning, among other things, the sources of our income, the nature and diversification of our assets, the amounts we distribute to our shareholders and the ownership of our shares. In order to meet these tests, we may be required to forego investments we might otherwise make. Thus, compliance with the REIT requirements may hinder our performance.

In particular, we must ensure that at the end of each calendar quarter, at least 75% of the value of our assets consists of cash, cash items, government securities and qualified real estate assets. The remainder of our investment in securities (other than government securities and qualified real estate assets) generally cannot include more than 10% of the outstanding voting securities of any one issuer or more than 10% of the total value of the outstanding securities of any one issuer. In addition, in general, no more than 5% of the value of our assets (other than government securities and qualified real estate assets) can consist of the securities of any one issuer, and no more than 20% of the value of our total assets can be represented by the securities of one or more taxable REIT subsidiaries. If we fail to comply with these requirements at the end of any calendar quarter, we must correct the failure within 30 days after the end of the calendar quarter or qualify for certain statutory relief provisions to avoid losing our REIT qualification and suffering adverse tax consequences. As a result, we may be required to liquidate otherwise attractive investments. These actions could have the effect of reducing our income and amounts available for distribution to our shareholders.

Dividends payable by REITs do not qualify for the reduced tax rates available for some dividends.

For non-corporate taxpayers the maximum tax rate applicable to “qualified dividend income” paid by regular “C” corporations to U.S. shareholders generally is 20%. Dividends payable by REITs, however, generally are not eligible for the reduced rates on qualified dividend income. Instead, our ordinary dividends generally are taxed at the higher tax rates applicable to ordinary income, the current maximum rate of which is 37%. However, for taxable years prior to 2026, individual stockholders are generally allowed to deduct 20% of the aggregate amount of ordinary dividends distributed by us, subject to certain limitations, which would reduce the maximum marginal effective tax rate for individuals on the receipt of such ordinary dividends to 29.6%.

Complying with REIT requirements may limit our ability to hedge effectively and may cause us to incur tax liabilities.

The REIT provisions of the Code substantially limit our ability to hedge our liabilities. Any income from a hedging transaction that we enter into to manage risk of interest rate changes, price changes or currency fluctuations with respect to borrowings made or to be made to acquire or carry real estate assets does not constitute “gross income” for purposes of the 75% or 95% gross income tests. To the extent that we enter into other types of hedging transactions, the income from those transactions is likely to be treated as non-qualifying income for purposes of both of the gross income tests. As a result of these rules, we may need to limit our use of advantageous hedging techniques or implement those hedges through taxable REIT subsidiaries. This could increase the cost of our hedging activities because any taxable REIT subsidiary that we may form would be subject to tax on gains or expose us to greater risks associated with changes in interest rates than we would otherwise want to bear. In addition, losses in taxable REIT subsidiaries will generally not provide any tax benefit, except for being carried forward against future taxable income in the taxable REIT subsidiaries.

Pursuant to the Tax Protection Agreement, the amount that Pillarstone is required to indemnify the Operating Partnership for certain tax liabilities reduces over the term of the Tax Protection Agreement.

In connection with the Contribution (as defined below), on December 8, 2016, the Operating Partnership entered into a Tax Protection Agreement (the “Tax Protection Agreement”) with Pillarstone Capital REIT (“Pillarstone REIT”), the general partner of Pillarstone, and Pillarstone pursuant to which Pillarstone agreed to indemnify the Operating Partnership for certain tax liabilities resulting from its recognition of income or gain prior to December 8, 2021 (a) if such liabilities result from a transaction involving a direct or indirect taxable disposition of all or a portion of the Pillarstone Properties or (b) if Pillarstone fails to maintain and allocate to the Operating Partnership for taxation purposes minimum levels of liabilities as specified in the Tax Protection Agreement, the result of which causes such recognition of income or gain and the Company incurs taxes that must be paid to maintain its REIT status for federal tax purposes.  However, the Tax Protection Agreement expires on the earlier of (x) December 8, 2021 and (y) the date on which the Operating Partnership disposes of 50% or more of the Pillarstone OP Units (as defined below) issued in connection with the Contribution.  Further, the amount that Pillarstone is required to indemnify the Operating Partnership reduces over the term of the Tax Protection Agreement as follows: on December 8^th of each year, the amount of tax liability recognized by the Operating Partnership during that year that Pillarstone is required to indemnify is reduced by 20 percentage points.  Once the Tax Protection Agreement has expired, the Company could be subject to additional taxes upon the occurrence of certain events that must be paid to maintain its REIT status for federal tax purposes.

Risks Related to Ownership of our Common Shares

Increases in market interest rates may result in a decrease in the value of our common shares.

One of the factors that may influence the price of our common shares will be the dividend distribution rate on the common shares (as a percentage of the price of our common shares) relative to market interest rates. If market interest rates rise, prospective purchasers of shares of our common shares may expect a higher distribution rate. Higher interest rates would not, however, result in more funds being available for distribution and, in fact, would likely increase our borrowing costs and might decrease our funds available for distribution. We therefore may not be able, or we may not choose, to provide a higher distribution rate. As a result, prospective purchasers may decide to purchase other securities rather than our common shares, which would reduce the demand for, and result in a decline in the market price of, our common shares.

Broad market fluctuations could negatively impact the market price of our common shares.

The stock market has experienced extreme price and volume fluctuations that have affected the market price of many companies in industries similar or related to ours and that have been unrelated to these companies’ operating performances. These broad market fluctuations could reduce the market price of our common shares. Furthermore, our operating results and prospects may be below the expectations of public market analysts and investors or may be lower than those of companies with comparable market capitalizations. Either of these factors could lead to a material decline in the market price of our common shares.

Maryland takeover statutes may deter others from seeking to acquire us and prevent shareholders from making a profit in such transactions.

The Maryland General Corporation Law (“MGCL”) contains many provisions, such as the business combination statute and the control share acquisition statute, that are designed to prevent, or have the effect of preventing, someone from acquiring control of us. The business combination statute, subject to limitations, prohibits certain business combinations between us and an “interested shareholder” (defined generally as any person who beneficially owns 10% or more of the voting power of our outstanding voting shares or an affiliate or associate of our Company who, at any time within the two-year period prior to the date in question, was the beneficial owner of 10% or more of the voting power of our then outstanding shares) or an affiliate of an interested shareholder for five years after the most recent date on which the person becomes an interested shareholder and thereafter imposes super-majority voting requirements on these combinations. The control share acquisition statute provides that “control shares” of our Company (defined as shares which, when aggregated with other shares controlled by the shareholder (except solely by virtue of a revocable proxy), entitle the shareholder to exercise one of three increasing ranges of voting power in electing trustees) acquired in a “control share acquisition” (defined as the direct or indirect acquisition of ownership or control of issued and outstanding control shares) have no voting rights except to the extent approved by our shareholders by the affirmative vote of at least two-thirds of all the votes entitled to be cast on the matter, excluding all interested shares.

We are currently subject to the control share acquisition statute, although our board of trustees may amend our Amended and Restated Bylaws, or our bylaws, without shareholder approval, to exempt any acquisition of our shares from the

17

statute. Our board of trustees has adopted a resolution exempting any business combination with any person from the business combination statute. The business combination statute (if our board of trustees revokes the foregoing exemption) and the control share acquisition statute could delay or prevent offers to acquire us and increase the difficulty of consummating any such offers, even if such a transaction would be in our shareholders’ best interest.

The MGCL, the Maryland REIT Law and our organizational documents limit shareholders’ rights to bring claims against our officers and trustees.

The MGCL and the Maryland REIT Law provide that a trustee will not have any liability as a trustee so long as he performs his duties in good faith, in a manner he reasonably believes to be in our best interests, and with the care that an ordinarily prudent person in a like position would use under similar circumstances. In addition, our declaration of trust provides that no trustee or officer will be liable to us or to any shareholder for money damages except to the extent that (a) the trustee or officer actually received an improper benefit or profit in money, property or services, for the amount of the benefit or profit in money, property, or services actually received; or (b) a judgment or the final adjudication adverse to the trustee or officer is entered in a proceeding based on a finding in the proceeding the trustee’s or officer’s action or failure to act was the result of active and deliberate dishonesty and was material to the cause of action adjudicated in the proceeding. Finally, our declaration of trust authorizes our Company to obligate itself, and our bylaws obligate us, to indemnify and advance expenses to our trustees and officers to the maximum extent permitted by Maryland law.

The terms of our employment agreements with our executive officers and severance arrangements with other employees and the terms of certain equity awards granted to our employees may deter others from seeking to acquire us or reduce the price of any such acquisition.

We have entered into employment agreements with our executive officers and severance arrangements with other of our employees, and have granted equity awards to a number of our employees. In certain cases, upon a change of control acquisition of us, such agreements and awards would entitle the officer or employee to severance payments and vesting of otherwise unvested awards. The cost of these payments and the impact of the vesting of such awards could deter a third party from seeking to acquire us or could cause the price payable to shareholders in connection with any such acquisition to be lower than it otherwise may have been. These effects could delay or prevent offers to acquire us and increase the difficulty in consummating any such offers, even if such a transaction would be in our shareholders’ best interests.

Future offerings of debt, which would be senior to our common shares upon liquidation, and/or preferred equity securities that may be senior to our common shares for purposes of distributions or upon liquidation, may adversely affect the market price of our common shares.

In the future, we may attempt to increase our capital resources by making additional offerings of debt or preferred equity securities, including medium-term notes, trust preferred securities, senior or subordinated notes and preferred shares. Upon liquidation, holders of our debt securities and preferred shares and lenders with respect to other borrowings will receive distributions of our available assets prior to the holders of our common shares. Additional equity offerings may dilute the holdings of our existing shareholders or reduce the market price of our common shares, or both. Holders of our common shares are not entitled to preemptive rights or other protections against dilution. Our preferred shares, if issued, could have a preference on liquidating distributions or a preference on distribution payments that could limit our ability to pay distributions to the holders of our common shares. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus, our common shareholders bear the risk of our future offerings reducing the market price of our common shares and diluting their share holdings in us.

Item 2.  Properties.

General

As of December 31, 2019, we wholly-owned 58 commercial properties, including 15 properties in Houston, eight properties in Dallas-Fort Worth, three properties in San Antonio, four properties in Austin, 27 properties in the Scottsdale and Phoenix, Arizona metropolitan areas, and one property in Buffalo Grove, Illinois, a suburb of Chicago.

Our tenants consist of national, regional and local businesses. Our properties generally attract a mix of tenants who provide basic staples, convenience items and services tailored to the specific cultures, needs and preferences of the surrounding community. These types of tenants are the core of our strategy of creating Whitestone-branded Community Centered Properties^®. We also believe daily sales of these basic items are less sensitive to fluctuations in the business cycle than higher priced retail items. Our largest tenant represented only 2.9% of our total revenues for the year ended December 31, 2019.

Substantially all of our revenues consist of base rents received under leases that generally have terms that range from less than one year to 15 years. The following table summarizes certain information relating to our properties as of December 31, 2019:

Commercial Properties	GLA	Average Occupancy as of  12/31/19		Annualized Base Rental Revenue  (in thousands) (1)		Average Annualized Base Rental Revenue Per Sq. Ft. (2)
Whitestone	4,953,571	90	%	$	87,290	$	19.58

⁽¹⁾    Calculated as the tenant’s actual December 31, 2019 base rent (defined as cash base rents including abatements) multiplied by 12.  Excludes vacant space as of December 31, 2019.  Because annualized base rental revenue is not derived from historical results that were accounted for in accordance with GAAP, historical results differ from the annualized amounts. Total abatements for leases in effect as of December 31, 2019 equaled approximately $76,000 for the month ended December 31, 2019.

⁽²⁾    Calculated as annualized base rent divided by GLA leased as of December 31, 2019.  Excludes vacant space as of December 31, 2019.

Our largest property, BLVD Place, a retail community purchased on May 26, 2017 and located in Houston, Texas, accounted for 13.4% of our total revenues for the year ended December 31, 2019. BLVD also accounted for 16.9% of our real estate assets, net of accumulated depreciation, for the year ended December 31, 2019.

As of December 31, 2019, approximately $171.4 million of our total debt of $645.9 million was secured by 8 of our properties with a combined net book value of $270.4 million.

Location of Properties

Of our 58 wholly-owned properties, 15 are located in the greater Houston metropolitan statistical area.  These 15 properties represent 30% of our revenue for the year ended December 31, 2019. An additional 27 of our wholly-owned properties are located in the greater Phoenix metropolitan statistical area and represent 42% of our revenue for the year ended December 31, 2019.

According to the United States Census Bureau, Houston and Phoenix ranked sixth and twelfth, respectively, in the largest United States metropolitan statistical areas as of December 31, 2019. The following table sets forth information about the unemployment rate in Houston, Phoenix and nationally during the last six months of 2019.

Insurance

We believe that we have property and liability insurance with reputable, commercially rated companies.  We also believe that our insurance policies contain commercially reasonable deductibles and limits, adequate to cover our properties.  We expect to maintain this type of insurance coverage and to obtain similar coverage with respect to any additional properties we acquire in the near future.  Further, we have title insurance relating to our properties in an aggregate amount that we believe to be adequate.

Item 3.  Legal Proceedings.

On December 12, 2017, a property owner that owns a land parcel adjacent to a Whitestone property filed suit against Whitestone Pinnacle of Scottsdale - Phase II, LLC (“Whitestone Pinnacle”) alleging breach of contract and resulting in the delay of the construction of the their assisted living facility. In May 2019, the claimant amended their report of damages and seeks approximately $2.7 million in restitution from Whitestone Pinnacle. The Company intends to vigorously defend the matter as it believes that these claims are without merit and that it has substantial legal and factual defenses to the claims and allegations contained in the complaint.

We are a participant in various other legal proceedings and claims that arise in the ordinary course of our business.  These matters are generally covered by insurance.  While the resolution of these matters cannot be predicted with certainty, we believe that the final outcome of these matters will not have a material effect on our financial position, results of operations or cash flows.

Item 4.  Mine Safety Disclosures.

Not applicable.

Item 7.  Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion of our financial condition and results of operations in conjunction with our audited consolidated financial statements and the notes thereto included in this Annual Report on Form 10-K.  For more detailed information regarding the basis of presentation for the following information, you should read the notes to our audited consolidated financial statements included in this Annual Report on Form 10-K.

Overview of Our Company

We are a fully integrated real estate company that owns and operates commercial properties in culturally diverse markets in major metropolitan areas.  Founded in 1998, we are internally managed with a portfolio of commercial properties in Texas, Arizona and Illinois.

In October 2006, our current management team joined the Company and adopted a strategic plan to acquire, redevelop, own and operate Community Centered Properties^®.  We define Community Centered Properties^® as visibly located properties in established or developing culturally diverse neighborhoods in our target markets.  We market, lease, and manage our centers to match tenants with the shared needs of the surrounding neighborhood.  Those needs may include specialty retail, grocery, restaurants and medical, educational and financial services.  Our goal is for each property to become a Whitestone-branded retail community that serves a neighboring five-mile radius around our property.  We employ and develop a diverse group of associates who understand the needs of our multicultural communities and tenants.

As of December 31, 2019, we wholly-owned 58 commercial properties consisting of:

Consolidated Operating Portfolio

• 53 properties that meet our Community Centered Properties^® strategy containing approximately 5.0 million square feet of GLA and having a total carrying amount (net of accumulated depreciation) of $943.6 million; and

Redevelopment, New Acquisitions Portfolio

• five parcels of land held for future development that meet our Community Centered Properties^® strategy having a total carrying amount of $18.4 million.

As of December 31, 2019, we had an aggregate of 1,400 tenants.  We have a diversified tenant base with our largest tenant comprising only 2.9% of our total revenues for the year ended December 31, 2019.  Lease terms for our properties range from less than one year for smaller tenants to more than 15 years for larger tenants.  Our leases generally include minimum monthly lease payments and tenant reimbursements for taxes, insurance and maintenance.  We completed 317 new and renewal leases during 2019, totaling 952,780 square feet and $88.0 million in total lease value.

We employed 108 full-time employees as of December 31, 2019.  As an internally managed REIT, we bear our own expenses of operations, including the salaries, benefits and other compensation of our employees, office expenses, legal, accounting and investor relations expenses and other overhead costs.

Real Estate Partnership

As of December 31, 2019, we, through our investment in Pillarstone OP, owned a majority interest in eight properties that do not meet our Community Centered Property® strategy containing approximately 0.9 million square feet of GLA (the “Pillarstone Properties”). We own 81.4% of the total outstanding units of Pillarstone OP, which we account for using the equity method. We also manage the day-to-day operations of Pillarstone OP.

How We Derive Our Revenue

Substantially all of our revenue is derived from rents received from leases at our properties. We had total revenues of approximately $119,251,000 for the year ended December 31, 2019 as compared to $119,863,000 for the year ended December 31, 2018, a decrease of $612,000, or 1%.

31

Known Trends in Our Operations; Outlook for Future Results

Rental Income

We expect our rental income to increase year-over-year due to the addition of properties and rent increases on renewal leases. The amount of net rental income generated by our properties depends principally on our ability to maintain the occupancy rates of currently leased space and to lease currently available space, newly acquired properties with vacant space, and space available from unscheduled lease terminations. The amount of rental income we generate also depends on our ability to maintain or increase rental rates in our submarkets. Over the past three years, we have seen modest improvement in the overall economy in our markets, which has allowed us to maintain overall occupancy rates, with slight increases in occupancy at certain of our properties, and to recognize modest increases in rental rates. We expect this trend to continue in 2020.

Scheduled Lease Expirations

We tend to lease space to smaller businesses that desire shorter term leases. As of December 31, 2019, approximately 28% of our GLA was subject to leases that expire prior to December 31, 2021.  Over the last three years, we have renewed expiring leases with respect to approximately 80% of our GLA. We routinely seek to renew leases with our existing tenants prior to their expiration and typically begin discussions with tenants as early as 18 months prior to the expiration date of the existing lease. Inasmuch as our early renewal program and other leasing and marketing efforts target these expiring leases, we hope to re-lease most of that space prior to expiration of the leases. In the markets in which we operate, we obtain and analyze market rental rates through review of third-party publications, which provide market and submarket rental rate data and through inquiry of property owners and property management companies as to rental rates being quoted at properties that are located in close proximity to our properties and we believe display similar physical attributes as our nearby properties. We use this data to negotiate leases with new tenants and renew leases with our existing tenants at rates we believe to be competitive in the markets for our individual properties. Due to the short term nature of our leases, and based upon our analysis of market rental rates, we believe that, in the aggregate, our current leases are at market rates. Market conditions, including new supply of properties, and macroeconomic conditions in our markets and nationally affecting tenant income, such as employment levels, business conditions, interest rates, tax rates, fuel and energy costs and other matters, could adversely impact our renewal rate and/or the rental rates we are able to negotiate. We continue to monitor our tenants’ operating performances as well as overall economic trends to evaluate any future negative impact on our renewal rates and rental rates, which could adversely affect our cash flow and ability to make distributions to our shareholders.

Acquisitions

We have continued to successfully grow our GLA through the acquisition of additional properties, and we expect to actively pursue and consummate additional acquisitions in the foreseeable future. We believe that over the next few years we will continue to have excellent opportunities to acquire quality properties at historically attractive prices. We have extensive relationships with community banks, attorneys, title companies and others in the real estate industry, which we believe enables us to take advantage of these market opportunities and maintain an active acquisition pipeline.

Property Acquisitions and Dispositions

We seek to acquire commercial properties in high-growth markets. Our acquisition targets are properties that fit our Community Centered Properties^® strategy.  We define Community Centered Properties^® as visibly located properties in established or developing, culturally diverse neighborhoods in our target markets, primarily in and around Phoenix, Chicago, Dallas, Fort Worth, San Antonio and Houston.  We may acquire properties in other high growth cities in the future. We market, lease and manage our centers to match tenants with the shared needs of the surrounding neighborhood.  Those needs may include specialty retail, grocery, restaurants and medical, educational and financial services.  Our goal is for each property to become a Whitestone-branded business center or retail community that serves a neighboring five-mile radius around our property.

Property Dispositions. We seek to continually upgrade our portfolio by opportunistically selling properties that do not have the potential to meet our Community Centered Property^® strategy and redeploying the sale proceeds into properties that better fit our strategy. Some of our properties that we owned at the time our current management team assumed the management of the Company may not fit our Community Centered Property^® strategy, and we may look for opportunities to dispose of these properties as we continue to execute our strategy. For example, in 2016, we sold three properties in the greater Houston area. In 2018, we sold two properties in the greater Houston area, and Pillarstone OP, through an indirect wholly owned subsidiary, Whitestone Industrial-Office, LLC, sold a portfolio of three properties in the greater Houston area. In 2019,

Pillarstone OP, through an indirect wholly owned subsidiary, Whitestone Industrial-Office, LLC, sold another portfolio of three properties in the greater Houston area.

On December 8, 2016, we, through our Operating Partnership, entered into a Contribution Agreement (the “Contribution Agreement”) with Pillarstone and Pillarstone REIT pursuant to which we contributed all of the equity interests in four of our wholly-owned subsidiaries: Whitestone CP Woodland Ph. 2, LLC, a Delaware limited liability company (“CP Woodland”); Whitestone Industrial-Office, LLC, a Texas limited liability company (“Industrial-Office”); Whitestone Offices, LLC, a Texas limited liability company (“Whitestone Offices”); and Whitestone Uptown Tower, LLC, a Delaware limited liability company (“Uptown Tower”, and together with CP Woodland, Industrial-Office and Whitestone Offices, the “Entities”) that own 14 non-core properties (the “Pillarstone Properties”) that do not fit our Community Centered Property^® strategy, to Pillarstone for aggregate consideration of approximately $84.0 million, consisting of (1) approximately $18.1 million Class A units representing limited partnership interests in Pillarstone (“Pillarstone OP Units”), issued at a price of $1.331 per Pillarstone OP Unit; and (2) the assumption of approximately $65.9 million of liabilities, consisting of (a) approximately $15.5 million of our liability under the 2018 Facility (see Note 9 to the accompanying consolidated financial statements); (b) an approximately $16.3 million promissory note of Uptown Tower under the Loan Agreement, dated as of September 26, 2013, between Uptown Tower, as borrower, and U.S. Bank, National Association, as successor to Morgan Stanley Mortgage Capital Holdings LLC, as lender; and (c) an approximately $34.1 million promissory note (the “Industrial-Office Promissory Note”) of Industrial-Office issued under the Loan Agreement, dated as of November 26, 2013 (the “Industrial-Office Loan Agreement”), between Industrial-Office, as borrower, and Jackson National Life Insurance Company, as lender (collectively, the “Contribution”).

In connection with the Contribution, on December 8, 2016, the Operating Partnership entered into an OP Unit Purchase Agreement (the “OP Unit Purchase Agreement”) with Pillarstone REIT and Pillarstone pursuant to which the Operating Partnership agreed to purchase up to an aggregate of $3.0 million of Pillarstone OP Units at a price of $1.331 per Pillarstone OP Unit over the two-year term of the OP Unit Purchase Agreement on the terms set forth therein. The OP Unit Purchase Agreement contains customary closing conditions and the parties have made certain customary representations, warranties and indemnifications to each other in the OP Unit Purchase Agreement. In addition, pursuant to the OP Unit Purchase Agreement, in the event of a Change of Control (as defined therein) of the Company, Pillarstone shall have the right, but not the obligation, to repurchase the Pillarstone OP Units issued thereunder from the Operating Partnership at their initial issue price of $1.331 per Pillarstone OP Unit.

In connection with the Contribution, (1) with respect to each Pillarstone Property (other than Uptown Tower), Whitestone TRS, Inc., a subsidiary of the Company (“Whitestone TRS”), entered into a Management Agreement with the Entity that owns such Pillarstone Property and (2) with respect to Uptown Tower, Whitestone TRS entered into a Management Agreement with Pillarstone (collectively, the “Management Agreements”). Pursuant to the Management Agreements with respect to each Pillarstone Property (other than Uptown Tower), Whitestone TRS agreed to provide certain property management, leasing and day-to-day advisory and administrative services to such Pillarstone Property in exchange for (x) a monthly property management fee equal to 5.0% of the monthly revenues of such Pillarstone Property and (y) a monthly asset management fee equal to 0.125% of GAV (as defined in each Management Agreement as, generally, the purchase price of the respective Pillarstone Property based upon the purchase price allocations determined pursuant to the Contribution Agreement, excluding all indebtedness, liabilities or claims of any nature) of such Pillarstone Property. Pursuant to the Management Agreement with respect to Uptown Tower, Whitestone TRS agreed to provide certain property management, leasing and day-to-day advisory and administrative services to Pillarstone in exchange for (x) a monthly property management fee equal to 3.0% of the monthly revenues of Uptown Tower and (y) a monthly asset management fee equal to 0.125% of GAV of Uptown Tower.

In connection with the Contribution, on December 8, 2016, the Operating Partnership entered into a Tax Protection Agreement with Pillarstone REIT and Pillarstone pursuant to which Pillarstone agreed to indemnify the Operating Partnership for certain tax liabilities resulting from its recognition of income or gain prior to December 8, 2021 if such liabilities result from a transaction involving a direct or indirect taxable disposition of all or a portion of the Pillarstone Properties or if Pillarstone fails to maintain and allocate to the Operating Partnership for taxation purposes minimum levels of liabilities as specified in the Tax Protection Agreement, the result of which causes such recognition of income or gain and the Company incurs taxes that must be paid to maintain its REIT status for federal tax purposes.

As of December 31, 2019, we owned approximately 81.4% of the total outstanding Pillarstone OP Units, which we account for under the equity method. Additionally, certain of our officers and trustees serve as officers and trustees of Pillarstone REIT. See Note 5 Investment in Real Estate Partnership to the accompanying consolidated financial statements for more information on our accounting treatment of our investment in Pillarstone OP.

Eldorado Plaza, a 221,577 square foot property, was 96% leased at the time of purchase and is located in McKinney, Texas, a suburb of Dallas, Texas.

Hurricane Harvey. In August 2017, Hurricane Harvey impacted the South Texas region, including Houston, Texas. The majority of our Houston properties incurred minor damage and as a result, we recorded approximately $0.5 million in Harvey related repairs recorded in property operation and maintenance expense for the year ended December 31, 2017.

Summary of Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements.  We prepared these financial statements in conformity with GAAP.  The preparation of these financial statements required us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods.  We based our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances.  Our results may differ from these estimates.  Currently, we believe that our accounting policies do not require us to make estimates using assumptions about matters that are highly uncertain.  For a better understanding of our accounting policies, you should read Note 2 to our accompanying consolidated financial statements in conjunction with this “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

We have described below the critical accounting policies that we believe could impact our consolidated financial statements most significantly.

Revenue Recognition.  All leases on our properties are classified as operating leases, and the related rental income is recognized on a straight-line basis over the terms of the related leases.  Differences between rental income earned and amounts due per the respective lease agreements are capitalized or charged, as applicable, to accrued rents and accounts receivable. Percentage rents are recognized as rental income when the thresholds upon which they are based have been met.  Recoveries from tenants for taxes, insurance, and other operating expenses are recognized as revenues in the period the corresponding costs are incurred. We combine lease and nonlease components in lease contracts, which includes combining base rent, recoveries, and percentage rents into a single line item, Rental, within the consolidated statements of operations and comprehensive income. Additionally, we have tenants who pay real estate taxes directly to the taxing authority. We exclude these costs paid directly by the tenant to third parties on our behalf from revenue recognized and the associated property operating expense.

Other property income primarily includes amounts recorded in connection with management fees and lease termination fees. Pillarstone OP pays us management fees for property management, leasing and day-to-day advisory and administrative services. Their obligations are satisfied over time. Pillarstone OP is billed monthly and typically pays quarterly. Revenues are governed by the Management Agreements (as defined in Note 5 to our accompanying consolidated financial statements). Refer to Note 5 to our accompanying consolidated financial statements for additional information regarding the Management Agreements with Pillarstone OP. Additionally, we recognize lease termination fees in the year that the lease is terminated and collection of the fee is probable. Amounts recorded within other property income are accounted for at the point in time when control of the goods or services transfers to the customer and our performance obligation is satisfied.

Profit-sharing Method. In accordance with the Financial Accounting Standards Board’s (“FASB”) guidance applicable to sales of real estate or interests therein, specifically FASB Accounting Standards Codification (“ASC”) 360-20, “Real Estate Sales,” Topic 606, “Revenue from Contracts with Customers” and ASC 610, “Other Income–Gains and Losses from the Derecognition of Nonfinancial Assets,” we did not recognize the sale of assets to Pillarstone OP in the Contribution and accounted for the transaction under the profit-sharing method for the year ended December 31, 2017. We recognized Pillarstone OP’s real estate assets and notes payables in our consolidated balance sheets. Additionally, the profits and losses of Pillarstone OP not attributable to the Company are reported as profit sharing expense. As a result of the adoption of Topic 606 and ASC 610, the Company derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and recognized the Company’s investment in Pillarstone OP under the equity method.

Equity Method. For the years prior to December 31, 2017, Pillarstone OP was accounted for under the profit-sharing method. In accordance with the FASB guidance applicable to sales of real estate or interests therein, specifically FASB ASC 360-20, “Real Estate Sales,” Topic 606, “Revenue from Contracts with Customers” and ASC 610, “Other Income–Gains and Losses from the Derecognition of Nonfinancial Assets,” we adopted Topic 606 and ASC 610 as of January 1, 2018, resulting in the derecognition of the underlying assets and liabilities associated with the Contribution (defined below) as of January 1, 2018 and the recognition of the Company’s investment in Pillarstone OP under the equity method. See Note 5 to our accompanying consolidated financial statements for additional disclosure on Pillarstone OP.

Development Properties.  Land, buildings and improvements are recorded at cost. Expenditures related to the development of real estate are carried at cost which includes capitalized carrying charges and development costs. Carrying charges (interest, real estate taxes, loan fees, and direct and indirect development costs related to buildings under construction), are capitalized as part of construction in progress. The capitalization of such costs ceases when the property, or any completed portion, becomes available for occupancy. For the year ended December 31, 2019, approximately $500,000 and $320,000 in interest expense and real estate taxes, respectively, were capitalized. For the year ended December 31, 2018, approximately

36

$574,000 and $365,000 in interest expense and real estate taxes, respectively, were capitalized. For the year ended December 31, 2017, approximately $439,000 and $277,000 in interest expense and real estate taxes, respectively, were capitalized. 

Acquired Properties and Acquired Lease Intangibles.  We allocate the purchase price of the acquired properties to land, building and improvements, identifiable intangible assets and to the acquired liabilities based on their respective fair values at the time of purchase. Identifiable intangibles include amounts allocated to acquired out-of-market leases, the value of in-place leases and customer relationship value, if any. We determine fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends and specific market and economic conditions that may affect the property. Factors considered by management in our analysis of determining the as-if-vacant property value include an estimate of carrying costs during the expected lease-up periods considering market conditions, and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and estimates of lost rentals at market rates during the expected lease-up periods, tenant demand and other economic conditions. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related expenses. Intangibles related to out-of-market leases and in-place lease value are recorded as acquired lease intangibles and are amortized as an adjustment to rental revenue or amortization expense, as appropriate, over the remaining terms of the underlying leases. Premiums or discounts on acquired out-of-market debt are amortized to interest expense over the remaining term of such debt.

Depreciation.  Depreciation is computed using the straight-line method over the estimated useful lives of 5 to 39 years for improvements and buildings, respectively.  Tenant improvements are depreciated using the straight-line method over the life of the improvement or remaining term of the lease, whichever is shorter.

Impairment.  We review our properties for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations.  We determine whether an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of the property, with the carrying cost of the property.  If impairment is indicated, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value.  Management has determined that there has been no impairment in the carrying value of our real estate assets as of December 31, 2019.

Accrued Rents and Accounts Receivable.  Included in accrued rents and accounts receivable are base rents, tenant reimbursements and receivables attributable to recording rents on a straight-line basis. We review the collectability of charges under our tenant operating leases on a regular basis, taking into consideration changes in factors such as the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area where the property is located. With the adoption of ASC No. 842, Leases (“Topic 842”), as of January 1, 2019 we recognize an adjustment to rental revenue if we deem it probable that the receivable will not be collected. Prior to the adoption of Topic 842, we recognized an allowance for doubtful accounts and bad debt expense of the specific rents receivable. Our review of collectability under our operating leases includes any accrued rental revenues related to the straight-line method of reporting rental revenue. As of December 31, 2019 and 2018, we had an allowance for uncollectible accounts of $11.2 million and $9.7 million, respectively. For the year ending December 31, 2019, we recorded an adjustment to rental revenue in the amount of $1.5 million. For the year ending December 31, 2018 and 2017, we recorded bad debt expense in the amount of $1.4 million and $2.3 million, respectively.

Unamortized Lease Commissions and Loan Costs.  Leasing commissions are amortized using the straight-line method over the terms of the related lease agreements.  Loan costs are amortized on the straight-line method over the terms of the loans, which approximates the interest method.  Costs allocated to in-place leases whose terms differ from market terms related to acquired properties are amortized over the remaining life of the respective leases.

Prepaids and Other Assets.  Prepaids and other assets include escrows established pursuant to certain mortgage financing arrangements for real estate taxes and insurance and acquisition deposits which include earnest money deposits on future acquisitions.

Federal Income Taxes.  We elected to be taxed as a REIT under the Code beginning with our taxable year ended December 31, 1999.  As a REIT, we generally are not subject to federal income tax on income that we distribute to our shareholders.  If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax on our taxable income at regular corporate rates.  We believe that we are organized and operate in such a manner as to qualify to be taxed as a REIT, and we intend to operate so as to remain qualified as a REIT for federal income tax purposes.

37

State Taxes.  We are subject to the Texas Margin Tax which is computed by applying the applicable tax rate (1% for us) to the profit margin, which, generally, will be determined for us as total revenue less a 30% standard deduction.  Although the Texas Margin Tax is not an income tax, FASB ASC 740, “Income Taxes” (“ASC 740”)applies to the Texas Margin Tax.  As of December 31, 2019, 2018 and 2017, we recorded a margin tax provision of $0.4 million, $0.4 million and $0.4 million, respectively.

Fair Value of Financial Instruments.  Our financial instruments consist primarily of cash, cash equivalents, accounts receivable, accounts and notes payable and investments in marketable securities.  The carrying value of cash, cash equivalents, accounts receivable and accounts payable are representative of their respective fair values due to their short-term nature.  The fair value of our long-term debt, consisting of fixed rate secured notes, variable rate secured notes and an unsecured revolving credit facility aggregate to approximately $653.7 million and $618.6 million as compared to the book value of approximately $645.9 million and $619.4 million as of December 31, 2019 and 2018, respectively. The fair value of our long-term debt is estimated on a Level 2 basis (as provided by ASC 820, “Fair Value Measurements and Disclosures”), using a discounted cash flow analysis based on the borrowing rates currently available to us for loans with similar terms and maturities, discounting the future contractual interest and principal payments.

The fair value of our loan guarantee to Pillarstone OP is estimated on a Level 3 basis (as provided by ASC 820, “Fair Value Measurements and Disclosures”), using a probability-weighted discounted cash flow analysis based on a discount rate, discounting the loan balance. The fair value of the loan guarantee is $0.1 million and $0.3 million as compared to the book value of approximately $0.1 million and $0.3 million as of December 31, 2019 and 2018, respectively.

Disclosure about fair value of financial instruments is based on pertinent information available to management as of December 31, 2019 and 2018. Although management is not aware of any factors that would significantly affect the fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since December 31, 2019 and current estimates of fair value may differ significantly from the amounts presented herein.

Derivative Instruments and Hedging Activities. We occasionally utilize derivative financial instruments, principally interest rate swaps, to manage our exposure to fluctuations in interest rates. We have established policies and procedures for risk assessment, and the approval, reporting and monitoring of derivative financial instruments. We recognize our interest rate swaps as cash flow hedges with the effective portion of the changes in fair value recorded in comprehensive income and subsequently reclassified into earnings in the period that the hedged transaction affects earnings. Any ineffective portion of a cash flow hedge’s change in fair value is recorded immediately into earnings. Our cash flow hedges are determined using Level 2 inputs under ASC 820. Level 2 inputs represent quoted prices in active markets for similar assets or liabilities; quoted prices in markets that are not active; and model-derived valuations whose inputs are observable. As of December 31, 2019, we consider our cash flow hedges to be highly effective.

Recent Accounting Pronouncements. In May 2014, the FASB issued guidance, as amended in subsequent updates, establishing a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and superseded most of the existing revenue recognition guidance. The standard also required an entity to recognize revenue to depict the transfer of promised 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 and also required certain additional disclosures. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a modified retrospective basis beginning January 1, 2018 and have derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and have recognized the Company’s investment in Pillarstone OP under the equity method of accounting. The Company made an adjustment which decreased the Company’s accumulated deficit as of January 1, 2018 by $19.1 million. See Note 5 to our accompanying consolidated financial statements for further details.

In February 2016, FASB issued ASU No. 2016-2 which provided the principles for the recognition, measurement, presentation and disclosure of leases. Additional guidance and targeted improvements to Topic 842 were made through the issuance of supplementary ASUs in July 2018, December 2018 and March 2019.

Effective January 1, 2019, we adopted the new lease accounting guidance in Topic 842. As the lessee and lessor, we have elected the package of practical expedients permitted in Topic 842. Accordingly, we have accounted for our existing operating leases as operating leases under the new guidance, without reassessing (a) whether the contract contains a lease under Topic 842, (b) whether classification of the operating lease would be different in accordance with Topic 842, or (c) whether the unamortized initial direct costs before transition adjustments (as of December 31, 2018) would have met the definition of initial direct costs in Topic 842 at lease commencement. Additionally, as the lessee and lessor we will use hindsight in determining the lease term and in assessing impairment of our right-of-use assets. As a result of the adoption of the new lease accounting

38

guidance, as the lessee, we recognized on January 1, 2019 (a) a lease liability of approximately $1.1 million, which represents the present value of the remaining lease payments of approximately $1.2 million discounted using our incremental borrowing rate of 4.5%, and (b) a right-of-use asset of approximately $1.1 million. The adoption of Topic 842 did not have a material impact to our net income and related per share amounts.

Upon adoption of Topic 842, lessees and lessors are required to apply a modified retrospective transition approach. Reporting entities are permitted to choose one of two methods to recognize and measure leases within the scope of Topic 842:

• Apply Topic 842 to each lease that existed at the beginning of the earliest comparative period presented in the financial statements as well as leases that commenced after that date. Under this method, prior comparative periods presented are adjusted. For leases that commenced prior to the beginning of the earliest comparative period presented, a cumulative-effect adjustment is recognized at that date.

• Apply the guidance to each lease that had commenced as of the beginning of the reporting period in which the entity first applies the leases standard with a cumulative-effect adjustment as of that date. Prior comparative periods would not be adjusted under this method.

We have elected an optional transition method that allows entities to initially apply Topic 842 at January 1, 2019, the date of adoption, and to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. As the lessor, we have not assessed unamortized legal costs as part of the package of practical expedients, and we will not make any adjustment to retained earnings at the date of adoption to write off unamortized legal costs. We will continue to amortize unamortized legal costs as of December 31, 2018 over the life of the respective leases. We did not have a cumulative-effect adjustment as of the adoption date. Additionally, the optional transition method does allow us to not have to apply the new standard (including disclosure requirements) to comparative periods presented. Those periods can continue to be presented in accordance with prior generally accepted accounting principles.

Topic 842 requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases and operating leases. Based on our election of the package of practical expedients, our existing commercial leases, where we are the lessor, continue to be accounted for as operating leases under the new standard. However, Topic 842 changed certain requirements regarding the classification of leases that could result in us recognizing certain long-term leases entered into or modified after January 1, 2019 as sales-type leases or finance leases, as opposed to operating leases. We will continue to monitor our leases following the adoption date to ensure that they are classified in accordance with the new lease standards.

We elected a practical expedient which allows lessors to not separate non-lease components from the lease component when the timing and pattern of transfer for the lease components and non-lease components are the same and if the lease component is classified as an operating lease. As a result, we now present all rentals and reimbursements from tenants as a single line item, Rental, within the consolidated statements of operations and comprehensive income.

We review the collectability of charges under our tenant operating leases on a regular basis, taking into consideration changes in factors such as the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area where the property is located. Each tenant is included in one of several portfolios and an allowance is calculated using the calculation methodology for the respective portfolio. With the adoption of Topic 842, we will recognize an adjustment to rental revenue if we deem it probable that the receivable will not be collected. Prior to the adoption of Topic 842, we recognized an allowance for doubtful accounts and bad debt expense of the specific rents receivable. Our review of collectability under our operating leases includes any accrued rental revenues related to the straight-line method of reporting rental revenue.

In November 2016, the FASB issued guidance requiring that the statement of cash flows explain the change during the period in the total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance effective January 1, 2018, and we have reconciled cash and cash equivalents and restricted cash and restricted cash equivalents on a retrospective basis, whereas under the previous guidance, we reported restricted cash and restricted cash equivalents under cash flows from financing activities.    

In January 2017, the FASB issued guidance clarifying the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or dispositions) of

39

assets or businesses. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a prospective basis beginning January 1, 2018 and believe the majority of our future acquisitions will qualify as asset acquisitions and the associated transaction costs will be capitalized as opposed to expensed under previous guidance.

In February 2017, the FASB issued guidance clarifying the scope of asset derecognition guidance, adding guidance for partial sales of nonfinancial assets and clarifying recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a modified retrospective basis beginning January 1, 2018 and have derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and have recognized the Company’s investment in Pillarstone OP under the equity method of accounting. The Company made an adjustment which decreased the Company’s accumulated deficit as of January 1, 2018 by $19.1 million. See Note 5 to our accompanying consolidated financial statements for further details.

Liquidity and Capital Resources

Our short-term liquidity requirements consist primarily of distributions to holders of our common shares and OP units, including those required to maintain our REIT status and satisfy our current quarterly distribution target of $0.2850 per share and OP unit, recurring expenditures, such as repairs and maintenance of our properties, non-recurring expenditures, such as capital improvements and tenant improvements, debt service requirements, and, potentially, acquisitions of additional properties.

During the year ended December 31, 2019, our cash provided from operating activities was $47,748,000 and our total dividends and distributions paid were $46,682,000. Therefore, we had cash flow from operations in excess of distributions of approximately $1,066,000. The 2019 Facility included a $300 million unsecured borrowing capacity under a revolving credit facility, two $50 million term loans and one $100 million term loan. The 2019 Facility also included an accordion feature that allowed the Operating Partnership to increase the borrowing capacity to $700 million, upon the satisfaction of certain conditions. We anticipate that cash flows from operating activities and our borrowing capacity under the 2019 Facility will provide adequate capital for our distributions, working capital requirements, anticipated capital expenditures and scheduled debt payments in the short term. We also believe that cash flows from operating activities and our borrowing capacity will allow us to make all distributions required for us to continue to qualify to be taxed as a REIT for federal income tax purposes.

Our long-term capital requirements consist primarily of maturities under our longer-term debt agreements, development and redevelopment costs, and potential acquisitions. We expect to meet our long-term liquidity requirements with net cash from operations, long-term indebtedness, sales of common shares, issuance of OP units, sales of underperforming and non-core properties and other financing opportunities, including debt financing. We believe we have access to multiple sources of capital to fund our long-term liquidity requirements, including the incurrence of additional debt and the issuance of additional equity. However, our ability to incur additional debt will be dependent on a number of factors, including our degree of leverage, the value of our unencumbered assets and borrowing restrictions that may be imposed by lenders. Our ability to access the equity markets will be dependent on a number of factors as well, including general market conditions for REITs and market perceptions about our Company.

We expect that our rental income will increase as we continue to acquire additional properties, subsequently increasing our cash flows generated from operating activities. We intend to finance the continued acquisition of such additional properties through equity issuances and through debt financing.

Our capital structure includes non-recourse secured debt that we assumed or originated on certain properties. We may hedge the future cash flows of certain debt transactions principally through interest rate swaps with major financial institutions.

As discussed in Note 2 to the accompanying consolidated financial statements, pursuant to the term of our $15.1 million 4.99% Note, due January 6, 2024 (see Note 9 to the accompanying consolidated financial statements), which is collateralized by our Anthem Marketplace property, we were required by the lenders thereunder to establish a cash management account controlled by the lenders to collect all amounts generated by our Anthem Marketplace property in order to collateralize such promissory note. Amounts in the cash management account are classified as restricted cash.

Cash and Cash Equivalents

We had cash and cash equivalents of approximately $15,643,000 at December 31, 2019, as compared to $13,786,000 at December 31, 2018.  The increase of $1,857,000 was primarily the result of the following:

Sources of Cash

• Cash flow from operations of $47,748,000 for the year ended December 31, 2019;

• Proceeds of $100,000,000 from issuance of bonds pursuant to the Note Agreement (as defined below);

• Proceeds from issuance of common shares, net of offering costs of $21,124,000;

• Net cash provided from investing activities of discontinued operations of $594,000;

• Net proceeds from financed receivable due from related party of $5,661,000;

41

Uses of Cash

• Payment of dividends and distributions to common shareholders and OP unit holders of $46,682,000;

• Acquisitions of real estate of $34,804,000;

• Additions to real estate of $13,243,000;

• Payments of loan origination costs of $2,970,000;

• Net payments of $66,700,000 to the 2019 Facility;

• Payments of notes payable of $8,095,000; and

• Repurchase of common shares of $776,000.

We place all cash in short-term, highly liquid investments that we believe provide appropriate safety of principal. 

Equity Offerings

On May 15, 2019, our new universal shelf registration statement on Form S-3 was declared effective by the SEC, allowing us to offer up to $750 million in securities from time to time, including common shares, preferred shares, debt securities, depositary shares and subscription rights.

On May 31, 2019, we entered into nine equity distribution agreements for an at-the-market equity distribution program (the “2019 equity distribution agreements”) providing for the issuance and sale of up to an aggregate of $100 million of the Company’s common shares. Actual sales will depend on a variety of factors determined by us from time to time, including (among others) market conditions, the trading price of our common shares, capital needs and our determinations of the appropriate sources of funding for us, and were made in transactions that will be deemed to be “at the-market” offerings as defined in Rule 415 under the Securities Act. We have no obligation to sell any of our common shares and can at any time suspend offers under the 2019 equity distribution agreements or terminate the 2019 equity distribution agreements. For the year ended December 31, 2019, we sold 1,612,389 common shares under the 2019 equity distribution agreements, with net proceeds to us of approximately $21.2 million. In connection with such sales, we paid compensation of approximately $324,000 to the sales agents.

We have used and anticipate using net proceeds from common shares issued pursuant to the 2019 equity distribution agreements for general corporate purposes, which may include acquisitions of additional properties, the repayment of outstanding indebtedness, capital expenditures, the expansion, redevelopment and/or re-tenanting of properties in our portfolio, working capital and other general purposes.

On April 25, 2017, we completed the sale of 8,018,500 common shares, including 1,018,500 common shares purchased by the underwriters upon exercise of their option to purchase additional common shares, at a public offering price per share of $13.00 (the “April 2017 Offering”). Total net proceeds from the April 2017 Offering, after deducting offering expenses, were approximately $99.9 million, which we contributed to the Operating Partnership in exchange for OP units. The Operating Partnership used the net proceeds from the April 2017 Offering to repay a portion of the 2018 Facility and for general corporate purposes, including funding a portion of the purchase price of BLVD Place and Eldorado Plaza.

On June 4, 2015, we entered into nine amended and restated equity distribution agreements (the “2015 equity distribution agreements”) for an at-the-market distribution program. Pursuant to the terms and conditions of the 2015 equity distribution agreements, we could issue and sell up to an aggregate of $50 million of our common shares pursuant to our Registration Statement on Form S-3 (File No. 333-203727), which expired on April 29, 2018. Actual sales depended on a variety of factors determined by us from time to time, including (among others) market conditions, the trading price of our common shares, capital needs and our determinations of the appropriate sources of funding for us, and were made in transactions that will be deemed to be “at-the-market” offerings as defined in Rule 415 under the Securities Act. We had no obligation to sell any of our common shares, and could at any time suspend offers under the 2015 equity distribution agreements or terminate the 2015 equity distribution agreements. For the year ended December 31, 2018, we did not sell any common shares under the 2015 equity distribution agreements. For the year ended December 31, 2017, we sold 1,324,038 common shares under the 2015 equity distribution agreements, with net proceeds to us of approximately $18.6 million. In connection with such sales, we paid compensation of approximately $0.3 million to the sales agents.

LIBOR is expected to be discontinued after 2021. A number of our current debt agreements have an interest rate tied to LIBOR. Some of these agreements provide procedures for determining an alternative base rate in the event that LIBOR is discontinued, but not all do so. Regardless, there can be no assurances as to what alternative base rates may be and whether such base rate will be more or less favorable than LIBOR and any other unforeseen impacts of the potential discontinuation of LIBOR. The Company intends to monitor the developments with respect to the potential phasing out of LIBOR after 2021 and work with its lenders to ensure any transition away from LIBOR will have minimal impact on its financial condition, but can provide no assurances regarding the impact of the discontinuation of LIBOR.

On March 22, 2019, we, through our Operating Partnership, entered into a Note Purchase and Guarantee Agreement (the “Note Agreement”) together with certain subsidiary guarantors as initial guarantor parties thereto (the “Subsidiary Guarantors”) and The Prudential Insurance Company of America and the various other purchasers named therein (collectively, the “Purchasers”) providing for the issuance and sale of $100 million of senior unsecured notes of the Operating Partnership, of which (i) $50 million are designated as 5.09% Series A Senior Notes due March 22, 2029 (the “Series A Notes”) and (ii) $50 million are designated as 5.17% Series B Senior Notes due March 22, 2029 (the “Series B Notes” and, together with the Series A Notes, the “Notes”) pursuant to a private placement that closed on March 22, 2019 (the “Private Placement”). Obligations under the Notes are unconditionally guaranteed by the Company and by the Subsidiary Guarantors.

The principal of the Series A Notes will begin to amortize on March 22, 2023 with annual principal payments of approximately $7.1 million. The principal of the Series B Notes will begin to amortize on March 22, 2025 with annual principal payments of $10.0 million. The Notes will pay interest quarterly on the 22nd day of March, June, September and December in each year until maturity.

The Operating Partnership may prepay at any time all, or from time to time part of, the Notes, in an amount not less than $1,000,000 in the case of a partial prepayment, at 100% of the principal amount so prepaid, plus a make-whole amount. The make-whole amount is equal to the excess, if any, of the discounted value of the remaining scheduled payments with respect to the Notes being prepaid over the aggregate principal amount of such Notes (as described in the Note Agreement). In addition, in connection with a Change of Control (as defined in the Note Purchase Agreement), the Operating Partnership is required to offer to prepay the Notes at 100% of the principal amount plus accrued and unpaid interest thereon.

The Note Agreement contains representations, warranties, covenants, terms and conditions customary for transactions of this type and substantially similar to the Operating Partnership’s existing senior revolving credit facility, including limitations on liens, incurrence of investments, acquisitions, loans and advances and restrictions on dividends and certain other restricted payments. In addition, the Note Agreement contains certain financial covenants substantially similar to the Operating Partnership’s existing senior revolving credit facility, including the following:

• maximum total indebtedness to total asset value ratio of 0.60 to 1.00;

• maximum secured debt to total asset value ratio of 0.40 to 1.00;

• minimum EBITDA (earnings before interest, taxes, depreciation, amortization or extraordinary items) to fixed charges ratio of 1.50 to 1.00;

• maximum other recourse debt to total asset value ratio of 0.15 to 1.00; and

• maintenance of a minimum tangible net worth (adjusted for accumulated depreciation and amortization) of $372 million plus 75% of the net proceeds from additional equity offerings (as defined therein).

In addition, the Note Agreement contains a financial covenant requiring that maximum unsecured debt not exceed the lesser of (i) an amount equal to 60% of the aggregate unencumbered asset value and (ii) the debt service coverage amount (as described in the Note Agreement). That covenant is substantially similar to the borrowing base concept contained in the Operating Partnership’s existing senior revolving credit facility.

The Note Agreement also contains default provisions, including defaults for non-payment, breach of representations and warranties, insolvency, non-performance of covenants, cross-defaults with other indebtedness and guarantor defaults. The occurrence of an event of default under the Note Agreement could result in the Purchasers accelerating the payment of all obligations under the Notes. The financial and restrictive covenants and default provisions in the Note Agreement are substantially similar to those contained in the Operating Partnership’s existing credit facility.

44

Net proceeds from the Private Placement were used to refinance existing indebtedness. The Notes have not been and will not be registered under the Securities Act of 1933, as amended (the “Securities Act”), and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act. The Notes were sold in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act.

On January 31, 2019, we, through our Operating Partnership, entered into an unsecured credit facility (the “2019 Facility”) with the lenders party thereto, Bank of Montreal, as administrative agent (the “Agent”), SunTrust Robinson Humphrey, as syndication agent, and BMO Capital Markets Corp., U.S. Bank National Association, SunTrust Robinson Humphrey and Regions Capital Markets, as co-lead arrangers and joint book runners. The 2019 Facility amended and restated the 2018 Facility (as defined below).

The 2019 Facility is comprised of the following three tranches:

• $250.0 million unsecured revolving credit facility with a maturity date of January 1, 2023 (the “2019 Revolver”);

• $165.0 million unsecured term loan with a maturity date of January 31, 2024 (“Term Loan A”); and

• $100.0 million unsecured term loan with a maturity date of October 30, 2022 (“Term Loan B” and together with Term Loan A, the “2019 Term Loans”).

Borrowings under the 2019 Facility accrue interest (at the Operating Partnership's option) at a Base Rate or an Adjusted LIBOR plus an applicable margin based upon our then existing leverage. As of December 31, 2019, the interest rate on the 2019 Revolver was 3.35%. The applicable margin for Adjusted LIBOR borrowings ranges from 1.40% to 1.90% for the 2019 Revolver and 1.35% to 1.90% for the 2019 Term Loans. Base Rate means the higher of: (a) the Agent’s prime commercial rate, (b) the sum of (i) the average rate quoted by the Agent by two or more federal funds brokers selected by the Agent for sale to the Agent at face value of federal funds in the secondary market in an amount equal or comparable to the principal amount for which such rate is being determined, plus (ii) 1/2 of 1.00%, and (c) the LIBOR rate for such day plus 1.00%. Adjusted LIBOR means LIBOR divided by one minus the Eurodollar Reserve Percentage. The Eurodollar Reserve Percentage means the maximum reserve percentage at which reserves are imposed by the Board of Governors of the Federal Reserve System on eurocurrency liabilities. Pursuant to the 2019 Facility, in the event of certain circumstances that result in the unavailability of LIBOR, including but not limited to LIBOR no longer being a widely recognized benchmark rate for newly originated dollar loans in the U.S. market, the Operating Partnership and the Agent will establish an alternate interest rate to LIBOR giving due consideration to prevailing market conventions and will amend the 2019 Facility to give effect to such alternate interest rate.

The 2019 Facility includes an accordion feature that will allow the Operating Partnership to increase the borrowing capacity by $200.0 million, upon the satisfaction of certain conditions. As of December 31, 2019, $374.5 million was drawn on the 2019 Facility and our unused borrowing capacity was $140.5 million, assuming that we use the proceeds of the 2019 Facility to acquire properties, or to repay debt on properties, that are eligible to be included in the unsecured borrowing base. The Company used $446.2 million of proceeds from the 2019 Facility to repay amounts outstanding under the 2018 Facility and intends to use the remaining proceeds from the 2019 Facility for general corporate purposes, including property acquisitions, debt repayment, capital expenditures, the expansion, redevelopment and re-tenanting of properties in its portfolio and working capital.

The Company, each direct and indirect material subsidiary of the Operating Partnership and any other subsidiary of the Operating Partnership that is a guarantor under any unsecured ratable debt will serve as a guarantor for funds borrowed by the Operating Partnership under the 2019 Facility. The 2019 Facility contains customary terms and conditions, including, without limitation, customary representations and warranties and affirmative and negative covenants including, without limitation, information reporting requirements, limitations on investments, acquisitions, loans and advances, mergers, consolidations and sales, incurrence of liens, dividends and restricted payments. In addition, the 2019 Facility contains certain financial covenants including the following:

• maximum total indebtedness to total asset value ratio of 0.60 to 1.00;

• maximum secured debt to total asset value ratio of 0.40 to 1.00;

• minimum EBITDA (earnings before interest, taxes, depreciation, amortization or extraordinary items) to fixed charges ratio of 1.50 to 1.00;

45

• maximum other recourse debt to total asset value ratio of 0.15 to 1.00; and

• maintenance of a minimum tangible net worth (adjusted for accumulated depreciation and amortization) of $372 million plus 75% of the net proceeds from additional equity offerings (as defined therein).

We serve as the guarantor for funds borrowed by the Operating Partnership under the 2019 Facility. The 2019 Facility contains customary terms and conditions, including, without limitation, affirmative and negative covenants such as information reporting requirements, maximum secured indebtedness to total asset value, minimum EBITDA (earnings before interest, taxes, depreciation, amortization or extraordinary items) to fixed charges, and maintenance of a minimum net worth. The 2019 Facility also contains customary events of default with customary notice and cure, including, without limitation, nonpayment, breach of covenant, misrepresentation of representations and warranties in a material respect, cross-default to other major indebtedness, change of control, bankruptcy and loss of REIT tax status.

On November 7, 2014, we, through our Operating Partnership, entered into an unsecured revolving credit facility (the “2014 Facility”) with the lenders party thereto, with BMO Capital Markets Corp., Wells Fargo Securities, LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and U.S. Bank, National Association, as co-lead arrangers and joint book runners, and Bank of Montreal, as administrative agent (the “Agent”). The 2014 Facility amended and restated our previous unsecured revolving credit facility. On October 30, 2015, we, through our Operating Partnership, entered into the First Amendment to the 2014 Facility (the “First Amendment”) with the guarantors party thereto, the lenders party thereto and the Agent. We refer to the 2014 Facility, as amended by the First Amendment, as the “2018 Facility.”

Pursuant to the First Amendment, the Company made the following amendments to the 2014 Facility:

• extended the maturity date of the $300 million unsecured revolving credit facility under the 2014 Facility (the “2018 Revolver”) to October 30, 2019 from November 7, 2018;

• converted $100 million of outstanding borrowings under the Revolver to a new $100 million unsecured term loan under the 2014 Facility (“Term Loan 3”) with a maturity date of October 30, 2022;

• extended the maturity date of the first $50 million unsecured term loan under the 2014 Facility (“Term Loan 1”) to October 30, 2020 from February 17, 2017; and

• extended the maturity date of the second $50 million unsecured term loan under the 2014 Facility (“Term Loan 2” and together with Term Loan 1 and Term Loan 3, the “2018 Term Loans”) to January 29, 2021 from November 7, 2019.

Borrowings under the 2018 Facility accrued interest (at the Operating Partnership's option) at a Base Rate or an Adjusted LIBOR plus an applicable margin based upon our then existing leverage. The applicable margin for Adjusted LIBOR borrowings ranged from 1.40% to 1.95% for the 2018 Revolver and 1.35% to 2.25% for the 2018 Term Loans. Base Rate means the higher of: (a) the Agent’s prime commercial rate, (b) the sum of (i) the average rate quoted by the Agent by two or more federal funds brokers selected by the Agent for sale to the Agent at face value of federal funds in the secondary market in an amount equal or comparable to the principal amount for which such rate is being determined, plus (ii) 1/2 of 1.00%, and (c) the LIBOR rate for such day plus 1.00%. Adjusted LIBOR means LIBOR divided by one minus the Eurodollar Reserve Percentage. The Eurodollar Reserve Percentage means the maximum reserve percentage at which reserves are imposed by the Board of Governors of the Federal Reserve System on eurocurrency liabilities.

Proceeds from the 2018 Facility were used for general corporate purposes, including property acquisitions, debt repayment, capital expenditures, the expansion, redevelopment and re-tenanting of properties in our portfolio and working capital.

On May 26, 2017, we, through our subsidiary, Whitestone BLVD Place LLC, a Delaware limited liability company, issued a $80.0 million promissory note to American General Life Insurance Company (the “BLVD Note”). The BLVD Note has a fixed interest rate of 3.72% and a maturity date of June 1, 2027. Proceeds from the BLVD Note were used to fund a portion of the purchase price of the acquisition of BLVD Place (See Note 4 to our accompanying consolidated financial statements).

46

On December 8, 2016, in connection with the Contribution, the Operating Partnership entered into the Second Amendment to the 2018 Facility and Reaffirmation of Guaranties (the “Second Amendment”) with Pillarstone OP, the Company and the other Guarantors party thereto, the lenders party thereto and the Agent. Pursuant to the Second Amendment, following the Contribution, Whitestone Offices, LLC and Whitestone CP Woodland Ph. 2, LLC were permitted to remain Material Subsidiaries (as defined in the 2018 Facility) and Guarantors under the 2018 Facility and their respective Pillarstone Properties were each permitted to remain an Eligible Property (as defined in the 2018 Facility) and be included in the Borrowing Base (as defined in the 2018 Facility) under the 2018 Facility. In addition, on December 8, 2016, Pillarstone OP entered into the Limited Guarantee (the “Limited Guarantee”) with the Agent, pursuant to which Pillarstone OP agreed to be joined as a party to the 2018 Facility to provide a limited guarantee up to the amount of availability generated by the Pillarstone Properties owned by Whitestone Offices, LLC and Whitestone CP Woodland Ph. 2, LLC.

As of December 31, 2019, our $171.4 million in secured debt was collateralized by eight properties with a carrying value of $270.4 million.  Our loans contain restrictions that would require the payment of prepayment penalties for the acceleration of outstanding debt and are secured by deeds of trust on certain of our properties and by assignment of the rents and leases associated with those properties.  In 2018, we were not in compliance with respect to the tangible Net Worth covenant as defined in the 2018 Facility and had received two waivers in 2018. Had we been unable to obtain a waiver or other suitable relief from the lenders under the 2018 Facility, an Event of Default (as defined in the 2018 Facility) would have occurred, permitting the lenders holding a majority of the commitments under the 2018 Facility to, among other things, accelerate the outstanding indebtedness, which would make it immediately due and payable. The 2019 Facility and the Notes contain similar tangible Net Worth covenants that reset at a new threshold and change the definition of Net Worth to add back accumulated depreciation. However, we can make no assurances that we will be in compliance with these covenants or other covenants under the 2019 Facility or the Notes in future periods or, if we are not in compliance, that we will be able to obtain a waiver. As of December 31, 2019, we were in compliance with all loan covenants.

Scheduled maturities of our outstanding debt as of December 31, 2019 were as follows (in thousands):

	Amount Due
Year	(in thousands)
2020	$	10,951
2021	1,611
2022	101,683
2023	137,363
2024	228,573
Thereafter	165,715
Total	$	645,896

Capital Expenditures

We continually evaluate our properties’ performance and value. We may determine it is in our shareholders’ best interest to invest capital in properties we believe have potential for increasing value. We also may have unexpected capital expenditures or improvements for our existing assets. Additionally, we intend to continue investing in similar properties outside of Texas and Arizona in cities with exceptional demographics to diversify market risk, and we may incur significant capital expenditures or make improvements in connection with any properties we may acquire.

47

Contractual Obligations

As of December 31, 2019, we had the following contractual obligations (see Note 9 of our accompanying consolidated financial statements for further discussion regarding the specific terms of our debt):

			Payment due by period (in thousands)
Consolidated Contractual Obligations	Total		Less than 1 year (2020)		1 - 3 years (2021 - 2022)		3 - 5 years (2023 - 2024)		More than 5 years (after 2024)

Total	$	769,662	$	38,504	$	155,522	$	392,710	$	182,926

⁽¹⁾   As of December 31, 2019, we had one loan totaling $109.5 million which bore interest at a floating rate.  The variable interest rate payments are based on LIBOR plus 1.40% to LIBOR plus 1.90%, which reflects our new interest rates under our 2019 Facility.  The information in the table above reflects our projected interest rate obligations for the floating rate payments based on one-month LIBOR as of December 31, 2019, of 1.76%.

⁽²⁾  The unused commitment fees on our unsecured credit facility, payable quarterly, are based on the average daily unused amount of our unsecured credit facility. The fees are 0.20% for facility usage greater than 50% or 0.25% for facility usage less than 50%. The information in the table above reflects our projected obligations for our unsecured credit facility based on our December 31, 2019 balance of $374.5 million.

Distributions

U.S. federal income tax law generally requires that a REIT distribute annually to its shareholders at least 90% of its REIT taxable income, without regard to the deduction for dividends paid and excluding net capital gains, and that it pay tax at regular corporate rates on any taxable income that it does not distribute. We currently, and intend to continue to, accrue distributions quarterly and make distributions in three monthly installments following the end of each quarter. For a discussion of our cash flow as compared to dividends, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources.”

The timing and frequency of our distributions are authorized and declared by our board of trustees in exercise of its business judgment based upon a number of factors, including:

• our funds from operations;

• our debt service requirements;

• our capital expenditure requirements for our properties;

• our taxable income, combined with the annual distribution requirements necessary to maintain REIT qualification;

• requirements of Maryland law;

We define “Same Stores” as properties that have been owned for the entire period being compared. For purposes of comparing the the year ended December 31, 2019 to the the year ended December 31, 2018, Same Stores include properties owned during the entire period from January 1, 2018 to December 31, 2019. We define “Non-Same Stores” as properties acquired since the beginning of the period being compared and properties that have been sold, but not classified as discontinued operations.

Revenues. The primary components of revenue are detailed in the table below (in thousands, except percentages):

	Year Ended December 31,

Total revenue	$	119,251		$	119,863	$	(612	)	(1	)%

⁽¹⁾ The Same Store tenant rent increase of $509,000 resulted from a decrease of $324,000 from the decrease in the average leased square feet to 4,382,812 from 4,399,134, offset by increase of $833,000 from the average rent per leased square foot increasing from $19.56 to $19.75.

⁽²⁾ The Same Store recoveries revenue increase of $1,082,000 is primarily attributable to increases in Same Store real estate taxes and property maintenance costs.

⁽³⁾ Same Store bad debt of $1,461,000 is included as a reduction of revenue for the year ended December 31, 2019. Prior to our adoption of Topic 842 in 2019, we recognized bad debt in total operating expenses. For the year ended December 31, 2018, the Same Store bad debt expense recognized in total operating expenses was $1,466,000. No bad debt expense is recognized in total operating expenses for 2019.

⁽⁴⁾  The decrease in Same Store other revenues is primarily comprised of decreased lease termination fees.

⁽⁵⁾  Non-Same Store total rental revenue for the year ended December 31, 2019 was primarily generated from our acquisition of the Las Colinas Village property on December 6, 2019. Non-Same Store total rental revenue for the year ended December 31, 2018 was generated from the Torrey Square and Bellnott Square properties prior to their sales during 2018. Please refer to Note 4 (Real Estate) to the accompanying consolidated financial statements for more information regarding the property acquisitions and property sales.

⁽⁶⁾  On December 27, 2018, Pillarstone OP, through an indirect wholly owned subsidiary, Whitestone Industrial-Office, LLC, sold a portfolio of three properties. The decrease in management fees is primarily due to less properties under management.

⁽¹⁾  Prior to our adoption of Topic 842 in 2019, we recorded an allowance for bad debt as a component of operating and maintenance expense. Subsequent to the adoption of Topic 842, we included the impact of tenant allowances as a reduction of revenue. Bad debt expense was $1,466,000 for the year ended December 31, 2018, and for the year ended December 31, 2019, we recorded a $1,461,000 reduction to Same Store revenue for tenant rent allowances.

⁽²⁾  Non-Same Store real estate tax expense for the year ended December 31, 2019 resulted from our acquisition of our Las Colinas Village property on December 6, 2019. Non-Same Store real estate tax expense for the year ended December 31, 2018 was incurred from the Torrey Square and Bellnott Square properties prior to their sales during 2018. Please refer to Note 4 (Real Estate) to the accompanying consolidated financial statements for more information regarding the property acquisitions and property sales.

⁽³⁾  Affiliated company rents are spaces that we lease from Pillarstone OP.

⁽⁴⁾  The general and administrative expense decrease was attributable to a $2,534,000 reduction in professional fees and other expenses incurred in connection with our 2018 Annual Meeting of Shareholders and a $275,000 decrease in share-based compensation expense, offset by increases of $812,000 in legal fees, $171,000 of salaries and benefits, net of allocated costs, and $206,000 in other general and administrative expenses. Please refer to Note 17 (Commitments and Contingencies) and Note 15 (Incentive Share Plan) to the accompanying consolidated financial statements for more information regarding legal fees and share-based compensation expense.

Interest, dividend and other investment income (3)	(659		)	(1,055		)	396		(38	)%
Total other expense	$	24,988		$	19,575		$	5,413	28	%

⁽¹⁾  The $1,108,000 increase in interest expense is attributable to an increase in our effective interest rate to 4.02% for the year ended December 31, 2019 as compared to 3.89% for the year ended December 31, 2018, resulting in a $844,000 increase in interest expense, and an increase in our average outstanding notes payable balance of $6,733,000 that resulted in $262,000 in increased interest expense. Amortization of loan fees increased interest expense by $2,000 for the year ended December 31, 2019 as compared to the year ended December 31, 2018.

⁽²⁾  During the year ended December 31, 2019, we received an $0.8 million principal payment in connection with the sale of two retail buildings we completed on November 29, 2016. In 2016, we provided seller-financing for the retail buildings, Webster Pointe and Centre South, and deferred a $1.7 million gain until principal payments on the seller-financed loan are received. The purchaser of the retail buildings sold the Webster Pointe property on November 15, 2019 and paid the entire principal balance of the loan related to Webster Pointe. As of December 31, 2019, we had a total of $2.7 million in deferred gains for seller-financed loans to be recognized upon receipt of principal payments. The $2.7 million in deferred gains includes amounts from the sale for Centre South discussed above and amounts from the sales of Royal Crest and Featherwood discussed below.

On September 24, 2018, we completed the sale of Torrey Square, located in Houston, Texas, for $8.7 million. We recorded a gain on sale of $4.4 million. On February 27, 2018, we completed the sale of Bellnott Square, located in Houston, Texas, for $4.7 million. We recorded a gain on sale of $0.3 million. We have not included Bellnott Square or Torrey Square in discontinued operations as neither property sale meets the definition of discontinued operations. Please refer to Note 4 (Real Estate) to the accompanying consolidated financial statements for more information regarding the property sales.

⁽³⁾  The $396,000 decrease in interest, dividend and other investment income was primarily comprised of a $411,000 decrease in interest income from our financed receivable from Pillarstone OP. As of December 31, 2019, the balance of the financed receivable from Pillarstone OP was paid off, and we do not expect to receive any interest income from financed receivables with Pillarstone OP in 2020.

Equity in earnings of real estate partnership. Our equity in earnings of real estate partnership, which is generated from our 81.4% ownership of Pillarstone OP, increased $6,645,000 from $8,431,000 for the year ended December 31, 2018 to $15,076,000 for the year ended December 31, 2019. Please refer to Note 5 (Investment in Real Estate Partnership) to the accompanying consolidated financial statements for more information regarding our investment in Pillarstone OP.

Gain on sale of property from discontinued operations. During the year ended December 31, 2019, we received a $0.7 million principal payment in connection with the sale of three office buildings we completed on December 31, 2014. In 2014, we provided seller-financing for the office buildings, Zeta, Royal Crest and Featherwood, and deferred a $2.5 million gain until principal payments on the seller-financed loan are received. The purchaser of the office buildings sold Zeta on April 24, 2019 and paid the entire principal balance of the loan related to Zeta. As of December 31, 2019, we had a total of $2.7 million in deferred gains for seller-financed loans to be recognized upon receipt of principal payments. The $2.7 million in deferred gains includes amounts from the sale for Royal Crest and Featherwood discussed above and amounts from the sale of Centre South that was completed in November 2016.

Real estate taxes.  Real estate taxes decreased $1,535,000, or 9%, during the year ended December 31, 2018 as compared to 2017. The $1,535,000 decrease was comprised of increases of $836,000 in Non-Same Store expense, $221,000 in Same Store expense and offset by decrease of $2,592,000 from the derecognition of Pillarstone Properties as a result of the adoption of Topic 606 and ASC 610. We actively work to keep our valuations and resulting taxes low because a majority of these taxes are charged to our tenants through triple net leases, and we strive to keep these charges to our tenants as low as possible.

Utilities.  Utilities decreased $1,044,000, or 19%, during the year ended December 31, 2018 as compared to 2017. The $1,044,000 decrease was comprised of increases of $237,000 in Non-Same Store expense and offset by decreases of $119,000 in our Same Store properties and $1,162,000 from the derecognition of Pillarstone Properties as a result of the adoption of Topic 606 and ASC 610.

Contract services. Contract services decreased $169,000, or 2%, during the year ended December 31, 2018 as compared to 2017. The $169,000 decrease was comprised of increases of $324,000 in Same Store expense and $651,000 in Non-Same Store expense, offset by a decrease of $1,144,000 from the derecognition of Pillarstone Properties as a result of the adoption of Topic 606 and ASC 610.

Repairs and maintenance. Repairs and maintenance decreased $1,152,000, or 23%, during the year ended December 31, 2018 as compared to 2017. The $1,152,000 decrease was comprised of decreases of $259,000 in Same Store expense and $913,000 from the derecognition of Pillarstone Properties as a result of the adoption of Topic 606 and ASC 610, partially offset by an increase of $20,000 in our Non-Same Store properties.

Bad debt.  Bad debt for the year ended December 31, 2018 decreased $965,000, or 41%, as compared to 2017. The $965,000 decrease was comprised of decreases of $506,000 in Same Store expense, $70,000 in our Non-Same Store properties, and $389,000 from the derecognition of Pillarstone Properties as a result of the adoption of Topic 606 and ASC 610.

Labor and other.  Labor and other expenses increased $186,000, or 5%, for year ended December 31, 2018 as compared to 2017. The $186,000 increase was comprised of increases of $861,000 in Non-Same Store expense and $300,000 in Same Store expense, offset by a decrease of $975,000 from the derecognition of Pillarstone Properties as a result of the adoption of Topic 606 and ASC 610.

General and administrative.  General and administrative expenses decreased approximately $668,000 for the year ended December 31, 2018 as compared to 2017. The decrease in general and administrative expenses included decreased share-based compensation expense costs of $3,668,000, decreased acquisition costs of $832,000, and decreased other expenses of $407,000, offset by increased professional fees primarily resulting from a proxy contest at our 2018 annual meeting of shareholders of $2,099,000, increased salaries and benefits, net of allocated costs of $2,080,000, and increased marketing costs of $60,000

Reconciliation of Non-GAAP Financial Measures

Funds From Operations (NAREIT) (“FFO”)

The National Association of Real Estate Investment Trusts (“NAREIT”) defines FFO as net income (loss) available to common shareholders computed in accordance with GAAP, excluding depreciation and amortization related to real estate, gains or losses from the sale of certain real estate assets, gains and losses from change in control, and impairment write-downs of certain real estate assets and investments in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity.  We calculate FFO in a manner consistent with the NAREIT definition and also include adjustments for our unconsolidated real estate partnership.

Management uses FFO as a supplemental measure to conduct and evaluate our business because there are certain limitations associated with using GAAP net income (loss) alone as the primary measure of our operating performance.

Historical cost accounting for real estate assets in accordance with GAAP implicitly assumes that the value of real estate assets diminishes predictably over time.  Because real estate values instead have historically risen or fallen with market conditions, management believes that the presentation of operating results for real estate companies that use historical cost accounting is insufficient by itself.  In addition, securities analysts, investors and other interested parties use FFO as the primary metric for comparing the relative performance of equity REITs.  

FFO should not be considered as an alternative to net income or other measurements under GAAP, as an indicator of our operating performance or to cash flows from operating, investing or financing activities as a measure of liquidity.  FFO does not reflect working capital changes, cash expenditures for capital improvements or principal payments on indebtedness. Although our calculation of FFO is consistent with that of NAREIT, there can be no assurance that FFO presented by us is comparable to similarly titled measures of other REITs.

Funds From Operations Core (“FFO Core”)

Management believes that the computation of FFO in accordance with NAREIT’s definition includes certain items that are not indicative of the results provided by our operating portfolio and affect the comparability of our period-over-period performance. These items include, but are not limited to, legal settlements, proxy contest fees, debt extension costs, non-cash share-based compensation expense, rent support agreement payments received from sellers on acquired assets, management fees from Pillarstone and acquisition costs. Therefore, in addition to FFO, management uses FFO Core, which we define to exclude such items. Management believes that these adjustments are appropriate in determining FFO Core as they are not indicative of the operating performance of our assets. In addition, we believe that FFO Core is a useful supplemental measure for the investing community to use in comparing us to other REITs as many REITs provide some form of adjusted or modified FFO. However, there can be no assurance that FFO Core presented by us is comparable to the adjusted or modified FFO of other REITs.

Property Net Operating Income (“NOI”)

Management believes that NOI is a useful measure of our property operating performance. We define NOI as operating revenues (rental and other revenues) less property and related expenses (property operation and maintenance and real estate taxes). Other REITs may use different methodologies for calculating NOI and, accordingly, our NOI may not be comparable to other REITs. Because NOI excludes general and administrative expenses, depreciation and amortization, involuntary conversion, interest expense, interest income, provision for income taxes, gain or loss on sale or disposition of assets, and our pro rata share of NOI of equity method investments, it provides a performance measure that, when compared year over year, reflects the revenues and expenses directly associated with owning and operating commercial real estate properties and the impact to operations from trends in occupancy rates, rental rates and operating costs, providing perspective not immediately apparent from net income. We use NOI to evaluate our operating performance since NOI allows us to evaluate the impact that factors such as occupancy levels, lease structure, lease rates and tenant base have on our results, margins and returns. In addition, management believes that NOI provides useful information to the investment community about our property and operating performance when compared to other REITs since NOI is generally recognized as a standard measure of property performance in the real estate industry. However, NOI should not be viewed as a measure of our overall financial performance since it does not reflect general and administrative expenses, depreciation and amortization, involuntary conversion, interest expense, interest income, provision for income taxes and gain or loss on sale or disposition of assets, the level of capital expenditures and leasing costs necessary to maintain the operating performance of our properties.

Below is the calculation of NOI and the reconciliation to net income, which we believe is the most comparable GAAP financial measure (in thousands):

Taxes

We elected to be taxed as a REIT under the Code beginning with our taxable year ended December 31, 1999.  As a REIT, we generally are not subject to federal income tax on income that we distribute to our shareholders.  If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax on our taxable income at regular corporate rates.  We believe that we are organized and operate in a manner to qualify and be taxed as a REIT, and we intend to operate so as to remain qualified as a REIT for federal income tax purposes.

Inflation

We anticipate that the majority of our leases will continue to be triple-net leases or otherwise provide that tenants pay for increases in operating expenses and will contain provisions that we believe will mitigate the effect of inflation.  In addition, many of our leases are for terms of less than five years, which allows us to adjust rental rates to reflect inflation and other changing market conditions when the leases expire.  Consequently, increases due to inflation, as well as ad valorem tax rate increases, generally do not have a significant adverse effect upon our operating results.

Off-Balance Sheet Arrangements

Guarantees We may guarantee the debt of a real estate partnership primarily because it allows the real estate partnership to obtain funding at a lower cost than could be obtained otherwise. This results in a higher return for the real estate partnership on its investment, and a higher return on our investment in the real estate partnership. We may receive a fee from the real estate partnership for providing the guarantee. Additionally, when we issue a guarantee, the terms of the real estate partnership’s partnership agreement typically provide that we may receive indemnification from the real estate partnership or have the ability to increase our ownership interest. See Note 5 to the accompanying consolidated financial statements for information related to our guarantees of our real estate partnership’s debt as of December 31, 2019 and 2018.

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk.

Our future income, cash flows and fair value relevant to our financial instruments depend upon prevailing market interest rates. Market risk refers to the risk of loss from adverse changes in market prices and interest rates. Based upon the nature of our operations, we are not subject to foreign exchange rate or commodity price risk. The principal market risk to which we are exposed is the risk related to interest rate fluctuations. Many factors, including governmental monetary and tax policies, domestic and international economic and political considerations, and other factors that are beyond our control contribute to interest rate risk. Our interest rate risk objective is to limit the impact of interest rate fluctuations on earnings and cash flows and to lower our overall borrowing costs. To achieve this objective, we manage our exposure to fluctuations in market interest rates for our borrowings through the use of fixed rate debt instruments to the extent that reasonably favorable rates are obtainable.

All of our financial instruments were entered into for other than trading purposes.

Fixed Interest Rate Debt

As of December 31, 2019, $536.4 million, or approximately 83%, of our outstanding debt was subject to fixed interest rates, which limit the risk of fluctuating interest rates. Though a change in the market interest rates affects the fair market value, it does not impact net income to shareholders or cash flows. Our total outstanding fixed interest rate debt has an average effective interest rate as of December 31, 2019 of approximately 4.1% per annum with expirations ranging from 2020 to 2029 (see Note 9 to our accompanying consolidated financial statements for further detail). Holding other variables constant, a 1% increase or decrease in interest rates would cause a $21.6 million decline or increase, respectively, in the fair value for our fixed rate debt.

Variable Interest Rate Debt

As of December 31, 2019, $109.5 million, or approximately 17%, of our outstanding debt was subject to floating interest rates of LIBOR plus 1.40% to 1.90% and not currently subject to a hedge. The impact of a 1% increase or decrease in interest rates on our floating rate debt would result in a decrease or increase, respectively, of annual net income of approximately $1.1 million.

Item 9A.  Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

In connection with the preparation of this Annual Report on Form 10-K, as of December 31, 2019, an evaluation was performed under the supervision and with the participation of the Company's management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rule 13a-15(e) under the Exchange Act. In performing this evaluation, management reviewed the selection, application and monitoring of our historical accounting policies. Based on that evaluation, the CEO and CFO concluded that as of December 31, 2019, these disclosure controls and procedures were effective and designed to ensure that the information required to be disclosed in our reports filed with the SEC is recorded, processed, summarized and reported on a timely basis.  In designing and evaluating disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.  Management is required to apply judgment in evaluating the cost-benefit relationship of possible controls and procedures. We maintain disclosure controls and procedures that are designed to provide a reasonable assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow for timely decisions regarding required disclosure.

65

Our management, under the supervision and with the participation of our CEO and CFO, carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2018. Based upon that evaluation, and in light of the material weakness in the design and operation of our internal control over financial reporting disclosed below, our CEO and CFO concluded that, as of December 31, 2018, our disclosure controls and procedures were not effective as of December 31, 2018 at the reasonable assurance level referenced above. In designing and evaluating disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. Management is required to apply judgment in evaluating the cost benefit relationship of possible controls and procedures.

Previously Identified Material Weakness

Our management conducted a process to assess the effectiveness of our internal control over financial reporting as of December 31, 2018, based on the criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO. This framework highlights that the control environment sets the tone of the organization, influences the control consciousness of its people, and is the foundation for all other components of internal control over financial reporting.

During the assessment process, we identified the following material weakness as of December 31, 2018 in the Company’s internal controls over financial reporting and disclosure controls and procedures.

• Application of New Accounting Pronouncements, including proper assessment of judgment items in complex accounting transactions - The Company did not have effective controls to ensure the proper application of new accounting pronouncements in its financial statements. After its review of the error and its internal controls over financial reporting and disclosure controls and procedures, the Company determined that it did not appropriately weigh its legal rights in its assessment of the transfer of control criteria under Topic 606 as it pertained to the Contribution.

The material weakness described above contributed to accounting errors that required the restatement of our consolidated financial statements for the first three quarterly periods of the year ended December 31, 2018.

As a result of the material weakness described above, management concluded that, as of December 31, 2018, our internal control over financial reporting was not effective. This material weakness was remediated as of June 30, 2019.

Remediation of Material Weakness in Internal Control over Financial Reporting

We completed and tested the following remediation efforts during the first and second quarters of 2019 with:

• The formation and implementation of a disclosure review committee, including outside technical advisors, the Chief Financial Officer, accounting staff, and other members of management. The committee meets quarterly, at a minimum, to provide guidance and oversight to ensure the proper implementation of the enhanced internal controls regarding the adoption of new accounting pronouncements. The committee met twice and reviewed its work with the Audit Committee prior to filing of the Quarterly Report on Form 10-Q for the three months ended March 31, 2019 and met once and reviewed its work with the Audit Committee prior to the filing of the Quarterly Report on Form 10-Q for the three and six months ended June 30, 2019.

• Enhancements to our internal controls regarding the adoption of new accounting pronouncements, including quarterly review of new accounting pronouncements with the Audit Committee and a discussion of key judgment areas.

• Engagement of outside technical experts to assist the Company in the application and adoption of new accounting pronouncements.

• Completion of training of accounting personnel.

• The hiring of additional qualified accounting staff.

As a result of the implementation of the remediation efforts above and based on our evaluation of our disclosure controls and procedures as of December 31, 2019, our principal executive and principal financial officer concluded that, as of such date, our disclosure controls and procedures were effective.

The Company's independent registered public accounting firm has issued a report on the effectiveness of the Company's internal control over financial reporting, which appears on page F-3 of this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

There have been no significant changes in our internal control over financial reporting during the Company’s quarter ended December 31, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting other than the remediation of material weakness discussed above.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and Shareholders of

Whitestone REIT:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Whitestone REIT and subsidiaries (the “Company”) as of December 31, 2019 and 2018, and the related consolidated statements of operations and comprehensive income, changes in equity, and cash flows for each of the years in the three year period ended December 31, 2019, and the related notes and schedules (collectively referred to as the “Consolidated Financial Statements”). In our opinion, the Consolidated Financial Statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the years in the three year period ended December 31, 2019, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”), and our report dated March 2, 2020, expressed an unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These Consolidated Financial Statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s Consolidated Financial Statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the Consolidated Financial Statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the Consolidated Financial Statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the Consolidated Financial Statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the Consolidated Financial Statements. We believe that our audits provide a reasonable basis for our opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and Shareholders of

Whitestone REIT:

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Whitestone REIT and subsidiaries (the “Company”) as of December 31, 2019, based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). In our opinion, the Company has maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control-Integrated Framework (2013) issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated balance sheets and the related consolidated statements of operations and comprehensive income, changes in equity, and cash flows of the Company, and our report dated March 2, 2020, expressed an unqualified opinion on the Company’s consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

WHITESTONE REIT AND SUBSIDIARIES

Notes to Consolidated Financial Statements

December 31, 2019

1.  DESCRIPTION OF BUSINESS AND NATURE OF OPERATIONS

Whitestone REIT (“Whitestone”) was formed as a real estate investment trust, pursuant to the Texas Real Estate Investment Trust Act on August 20, 1998.  In July 2004, we changed our state of organization from Texas to Maryland pursuant to a merger where we merged directly with and into a Maryland real estate investment trust formed for the sole purpose of the reorganization and the conversion of each of our outstanding common shares of beneficial interest of the Texas entity into 1.42857 common shares of beneficial interest of the Maryland entity.  We serve as the general partner of Whitestone REIT Operating Partnership, L.P. (the “Operating Partnership” or “WROP” or “OP”), which was formed on December 31, 1998 as a Delaware limited partnership.  We currently conduct substantially all of our operations and activities through the Operating Partnership.  As the general partner of the Operating Partnership, we have the exclusive power to manage and conduct the business of the Operating Partnership, subject to certain customary exceptions.  As of December 31, 2019, 2018 and 2017, we owned 58, 57, and 73 commercial properties, respectively, in and around Austin, Chicago, Dallas-Fort Worth, Houston, Phoenix and San Antonio.

As of December 31, 2019, these properties consist of:

Consolidated Operating Portfolio

• 53 wholly-owned properties that meet our Community Centered Properties^® strategy; and

• five parcels of land held for future development.

As of December 31, 2019, we, through our equity-method investment in Pillarstone Capital REIT Operating Partnership LP (“Pillarstone” or “Pillarstone OP”), owned a majority interest in eight properties that do not meet our Community Centered Property® strategy containing approximately 0.9 million square feet of GLA (the “Pillarstone Properties”). We own 81.4% of the total outstanding units of Pillarstone OP, which we account for using the equity method. We also manage the day-to-day operations of Pillarstone OP.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Consolidation.  We are the sole general partner of the Operating Partnership and possess full legal control and authority over the operations of the Operating Partnership.  As of December 31, 2019, 2018 and 2017, we owned a majority of the partnership interests in the Operating Partnership. Consequently, the accompanying consolidated financial statements include the accounts of the Operating Partnership.

Noncontrolling interest in the accompanying consolidated financial statements represents the share of equity and earnings of the Operating Partnership allocable to holders of partnership interests other than us.  Net income or loss is allocated to noncontrolling interests based on the weighted-average percentage ownership of the Operating Partnership during the year.  Issuance of additional common shares of beneficial interest in Whitestone (the “common shares”) and units of limited partnership interest in the Operating Partnership that are convertible into cash or, at our option, common shares on a one-for-one basis (the “OP units”) changes the percentage of ownership interests of both the noncontrolling interests and Whitestone.

Profit-sharing Method. In accordance with the Financial Accounting Standards Board’s (“FASB”) guidance applicable to sales of real estate or interests therein, specifically FASB Accounting Standards Codification (“ASC”) 360-20, “Real Estate Sales,” Topic 606, “Revenue from Contracts with Customers” and ASC 610, “Other Income–Gains and Losses from the Derecognition of Nonfinancial Assets,” we did not recognize the sale of assets to Pillarstone OP in the Contribution (as defined in Note 5) and accounted for the transaction under the profit-sharing method for the year ended December 31, 2017. We recognized Pillarstone OP’s real estate assets and notes payables in our consolidated balance sheets. Additionally, the profits and losses of Pillarstone OP not attributable to the Company are reported as profit sharing expense. As a result of the adoption of Topic 606 and ASC 610, the Company derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and recognized the Company’s investment in Pillarstone OP under the equity method.

Equity Method. For the years prior to December 31, 2017, Pillarstone OP was accounted for under the profit-sharing method. We adopted Topic 606 and ASC 610 as of January 1, 2018, resulting in the derecognition of the underlying assets and

F- 12

WHITESTONE REIT AND SUBSIDIARIES

Notes to Consolidated Financial Statements

December 31, 2019

liabilities associated with the Contribution (defined below) as of January 1, 2018 and the recognition of the Company’s investment in Pillarstone OP under the equity method. See Note 5 for additional disclosure on Pillarstone OP.

As of December 31, 2019, we, through our investment in Pillarstone OP, owned a majority interest in eight properties that do not meet our Community Centered Property® strategy containing approximately 0.9 million square feet of GLA. We own 81.4% of the total outstanding units of Pillarstone OP. We also manage the day-to-day operations of Pillarstone OP. In this Annual Report on Form 10-K, unless otherwise indicated, we do not include the Pillarstone Properties when we refer to our properties.

Basis of Accounting.  Our financial records are maintained on the accrual basis of accounting whereby revenues are recognized when earned and expenses are recorded when incurred.

Use of Estimates.   The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Significant estimates that we use include the estimated fair values of properties acquired, the estimated useful lives for depreciable and amortizable assets and costs, the estimated allowance for doubtful accounts, the estimated fair value of interest rate swaps and the estimates supporting our impairment analysis for the carrying values of our real estate assets.  Actual results could differ from those estimates.

Reclassifications.  We have reclassified certain prior year amounts in the accompanying consolidated financial statements in order to be consistent with the current fiscal year presentation. Other than the effects noted below, these reclassifications had no effect on net income, total assets, total liabilities or equity.

Restricted Cash. We classify all cash pledged as collateral to secure certain obligations and all cash whose use is limited as restricted cash. During 2015, pursuant to the terms of our $15.1 million4.99% Note, due January 6, 2024, which is collateralized by our Anthem Marketplace property, we were required by the lenders thereunder to establish a cash management account controlled by the lenders to collect all amounts generated by our Anthem Marketplace property in order to collateralize such promissory note.

Share-Based Compensation.   From time to time, we award nonvested restricted common share awards or restricted common share unit awards, which may be converted into common shares, to executive officers and employees under our 2018 Long-Term Equity Incentive Ownership Plan (the “2018 Plan”).  Awarded shares and units vest when certain performance conditions are met.  We recognize compensation expense when achievement of the performance conditions is probable based on management’s most recent estimates using the fair value of the shares as of the grant date.  We recognized $6.5 million, $6.8 million and $10.4 million in share-based compensation expense for the years ended December 31, 2019, 2018 and 2017, respectively.  

At our annual meeting of shareholders on May 11, 2017, our shareholders voted to approve the 2018 Plan. The 2018 Plan provides for the issuance of up to 3,433,831 common shares and OP units pursuant to awards under the 2018 Plan. The 2018 Plan became effective on July 30, 2018, which was the day after the 2008 Plan expired.

Noncontrolling Interests.  Noncontrolling interests are the portion of equity in a subsidiary not attributable to a parent.  The ownership interests not held by the parent are considered noncontrolling interests.  Accordingly, we have reported noncontrolling interests in equity on the consolidated balance sheets but separate from Whitestone’s equity.  On the consolidated statements of operations and comprehensive income, subsidiaries are reported at the consolidated amount, including both the amount attributable to Whitestone and noncontrolling interests.  Consolidated statements of changes in equity are included for both quarterly and annual financial statements, including beginning balances, activity for the period and ending balances for shareholders’ equity, noncontrolling interests and total equity.

Revenue Recognition.  All leases on our properties are classified as operating leases, and the related rental income is recognized on a straight-line basis over the terms of the related leases.  Differences between rental income earned and amounts due per the respective lease agreements are capitalized or charged, as applicable, to accrued rents and accounts receivable. Percentage rents are recognized as rental income when the thresholds upon which they are based have been met.  Recoveries from tenants for taxes, insurance, and other operating expenses are recognized as revenues in the period the corresponding costs are incurred. We combine lease and nonlease components in lease contracts, which includes combining base rent,

recoveries, and percentage rents into a single line item, Rental, within the consolidated statements of operations and comprehensive income. Additionally, we have tenants who pay real estate taxes directly to the taxing authority. We exclude these costs paid directly by the tenant to third parties on our behalf from revenue recognized and the associated property operating expense.

Other property income primarily includes amounts recorded in connection with management fees and lease termination fees. Pillarstone OP pays us management fees for property management, leasing and day-to-day advisory and administrative services. Their obligations are satisfied over time. Pillarstone OP is billed monthly and typically pays quarterly. Revenues are governed by the Management Agreements (as defined in Note 5). Refer to Note 5 to our accompanying consolidated financial statements for additional information regarding the Management Agreements with Pillarstone OP. Additionally, we recognize lease termination fees in the year that the lease is terminated and collection of the fee is probable. Amounts recorded within other property income are accounted for at the point in time when control of the goods or services transfers to the customer and our performance obligation is satisfied.

Cash and Cash Equivalents.  We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.  Cash and cash equivalents as of December 31, 2019 and 2018 consisted of demand deposits at commercial banks and brokerage accounts. We may have net book credit balances in our primary disbursement accounts at the end of a reporting period. We classify such credit balances as accounts payable in our consolidated balance sheets as checks presented for payment to these accounts are not payable by our banks under overdraft arrangements, and, therefore, do not represent short-term borrowings.

Marketable Securities. We classify our existing marketable equity securities as available-for-sale in accordance with the Financial Accounting Standards Board’s (“FASB”) Investments-Debt and Equity Securities guidance. These securities are carried at fair value with unrealized gains and losses reported in equity as a component of accumulated other comprehensive income or loss. The fair value of the marketable securities is determined using Level 1 inputs under FASB Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures.” Level 1 inputs represent quoted prices available in an active market for identical investments as of the reporting date. Gains and losses on securities sold are based on the specific identification method, and are reported as a component of interest, dividend and other investment income.

Real Estate

Development Properties.  Land, buildings and improvements are recorded at cost. Expenditures related to the development of real estate are carried at cost which includes capitalized carrying charges and development costs. Carrying charges (interest, real estate taxes, loan fees, and direct and indirect development costs related to buildings under construction) are capitalized as part of construction in progress. The capitalization of such costs ceases when the property, or any completed portion, becomes available for occupancy. For the year ended December 31, 2019, approximately $500,000 and $320,000 in interest expense and real estate taxes, respectively, were capitalized. For the year ended December 31, 2018, approximately $574,000 and $365,000 in interest expense and real estate taxes, respectively, were capitalized. For the year ended December 31, 2017, approximately $439,000 and $277,000 in interest expense and real estate taxes, respectively, were capitalized. 

Acquired Properties and Acquired Lease Intangibles.  We allocate the purchase price of the acquired properties to land, building and improvements, identifiable intangible assets and to the acquired liabilities based on their respective fair values at the time of purchase. Identifiable intangibles include amounts allocated to acquired out-of-market leases, the value of in-place leases and customer relationship value, if any. We determine fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends and specific market and economic conditions that may affect the property. Factors considered by management in our analysis of determining the as-if-vacant property value include an estimate of carrying costs during the expected lease-up periods considering market conditions, and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and estimates of lost rentals at market rates during the expected lease-up periods, tenant demand and other economic conditions. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related expenses. Intangibles related to out-of-market leases and in-place lease value are recorded as acquired lease intangibles and are amortized as an adjustment to rental revenue or amortization expense, as appropriate, over the remaining terms of the underlying leases. Premiums or discounts on acquired out-of-market debt are amortized to interest expense over the remaining term of such debt.

Depreciation.  Depreciation is computed using the straight-line method over the estimated useful lives of 5 to 39 years for improvements and buildings, respectively.  Tenant improvements are depreciated using the straight-line method over the life of the improvement or remaining term of the lease, whichever is shorter.

Impairment.  We review our properties for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations.  We determine whether an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of the property, with the carrying cost of the property.  If impairment is indicated, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value.  Management has determined that there has been no impairment in the carrying value of our real estate assets as of December 31, 2019.

Accrued Rents and Accounts Receivable.  Included in accrued rents and accounts receivable are base rents, tenant reimbursements and receivables attributable to recording rents on a straight-line basis. We review the collectability of charges under our tenant operating leases on a regular basis, taking into consideration changes in factors such as the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area where the property is located. With the adoption of ASC No. 842, Leases (“Topic 842”), as of January 1, 2019 we recognize an adjustment to rental revenue if we deem it probable that the receivable will not be collected. Prior to the adoption of Topic 842, we recognized an allowance for doubtful accounts and bad debt expense of the specific rents receivable. Our review of collectability under our operating leases includes any accrued rental revenues related to the straight-line method of reporting rental revenue. As of December 31, 2019 and 2018, we had an allowance for uncollectible accounts of $11.2 million and $9.7 million, respectively. For the year ending December 31, 2019, we recorded an adjustment to rental revenue in the amount of $1.5 million. For the year ending December 31, 2018 and 2017, we recorded bad debt expense in the amount of $1.4 million and $2.3 million, respectively.

Unamortized Lease Commissions and Loan Costs.  Leasing commissions are amortized using the straight-line method over the terms of the related lease agreements.  Loan costs are amortized on the straight-line method over the terms of the loans, which approximates the interest method.  Costs allocated to in-place leases whose terms differ from market terms related to acquired properties are amortized over the remaining life of the respective leases.

Prepaids and Other Assets.  Prepaids and other assets include escrows established pursuant to certain mortgage financing arrangements for real estate taxes and insurance and acquisition deposits which include earnest money deposits on future acquisitions.

Federal Income Taxes.  We elected to be taxed as a REIT under the Code beginning with our taxable year ended December 31, 1999.  As a REIT, we generally are not subject to federal income tax on income that we distribute to our shareholders.  If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax on our taxable income at regular corporate rates.  We believe that we are organized and operate in such a manner as to qualify to be taxed as a REIT, and we intend to operate so as to remain qualified as a REIT for federal income tax purposes.

State Taxes.  We are subject to the Texas Margin Tax, which is computed by applying the applicable tax rate (1% for us) to the profit margin, which, generally, will be determined for us as total revenue less a 30% standard deduction.  Although the Texas Margin Tax is not considered an income tax, FASB ASC 740, “Income Taxes” (“ASC 740”)applies to the Texas Margin Tax.  As of December 31, 2019, 2018 and 2017, we recorded a margin tax provision of $0.4 million, $0.4 million and $0.4 million, respectively.

Fair Value of Financial Instruments.  Our financial instruments consist primarily of cash, cash equivalents, accounts receivable, accounts and notes payable and investments in marketable securities.  The carrying value of cash, cash equivalents, accounts receivable and accounts payable are representative of their respective fair values due to their short-term nature.  The fair value of our long-term debt, consisting of fixed rate secured notes, variable rate secured notes and an unsecured revolving credit facility aggregate to approximately $653.7 million and $618.6 million as compared to the book value of approximately $645.9 million and $619.4 million as of December 31, 2019 and 2018, respectively. The fair value of our long-term debt is estimated on a Level 2 basis (as provided by ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”)), using a discounted cash flow analysis based on the borrowing rates currently available to us for loans with similar terms and maturities, discounting the future contractual interest and principal payments.

The fair value of our loan guarantee to Pillarstone OP is estimated on a Level 3 basis (as provided by ASC 820, “Fair Value Measurements and Disclosures”), using a probability-weighted discounted cash flow analysis based on a discount rate, discounting the loan balance. The fair value of the loan guarantee is $0.1 million and $0.3 million as compared to the book value of approximately $0.1 million and $0.3 million as of December 31, 2019 and 2018, respectively.

Disclosure about fair value of financial instruments is based on pertinent information available to management as of December 31, 2019 and 2018. Although management is not aware of any factors that would significantly affect the fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since December 31, 2019 and current estimates of fair value may differ significantly from the amounts presented herein.

Derivative Instruments and Hedging Activities. We utilize derivative financial instruments, principally interest rate swaps, to manage our exposure to fluctuations in interest rates. We have established policies and procedures for risk assessment, and the approval, reporting and monitoring of derivative financial instruments. We recognize our interest rate swaps as cash flow hedges with the effective portion of the changes in fair value recorded in comprehensive income and subsequently reclassified into earnings in the period that the hedged transaction affects earnings. Any ineffective portion of a cash flow hedge’s change in fair value is recorded immediately into earnings. Our cash flow hedges are determined using Level 2 inputs under ASC 820. Level 2 inputs represent quoted prices in active markets for similar assets or liabilities; quoted prices in markets that are not active; and model-derived valuations whose inputs are observable. As of December 31, 2019, we consider our cash flow hedges to be highly effective.

Concentration of Risk.  Substantially all of our revenues are obtained from office, warehouse and retail locations in the Austin, Chicago, Dallas-Fort Worth, Houston, Phoenix and San Antonio metropolitan areas. We maintain cash accounts in major U.S. financial institutions. The terms of these deposits are on demand to minimize risk. The balances of these accounts sometimes exceed the federally insured limits, although no losses have been incurred in connection with these deposits.

Recent Accounting Pronouncements. In May 2014, the FASB issued guidance, as amended in subsequent updates, establishing a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and superseded most of the existing revenue recognition guidance. The standard also required an entity to recognize revenue to depict the transfer of promised 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 and also required certain additional disclosures. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a modified retrospective basis beginning January 1, 2018 and have derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and have recognized the Company’s investment in Pillarstone OP under the equity method of accounting. The Company made an adjustment which decreased the Company’s accumulated deficit as of January 1, 2018 by $19.1 million. See Note 5 for further details.

In February 2016, FASB issued ASU No. 2016-2 which provided the principles for the recognition, measurement, presentation and disclosure of leases. Additional guidance and targeted improvements to Topic 842 were made through the issuance of supplementary ASUs in July 2018, December 2018 and March 2019.

Effective January 1, 2019, we adopted the new lease accounting guidance in Topic 842. As the lessee and lessor, we have elected the package of practical expedients permitted in Topic 842. Accordingly, we have accounted for our existing operating leases as operating leases under the new guidance, without reassessing (a) whether the contract contains a lease under Topic 842, (b) whether classification of the operating lease would be different in accordance with Topic 842, or (c) whether the unamortized initial direct costs before transition adjustments (as of December 31, 2018) would have met the definition of initial

F- 16

Notes to Consolidated Financial Statements

December 31, 2019

direct costs in Topic 842 at lease commencement. Additionally, as the lessee and lessor we will use hindsight in determining the lease term and in assessing impairment of our right-of-use assets. As a result of the adoption of the new lease accounting guidance, as the lessee, we recognized on January 1, 2019 (a) a lease liability of approximately $1.1 million, which represents the present value of the remaining lease payments of approximately $1.2 million discounted using our incremental borrowing rate of 4.5%, and (b) a right-of-use asset of approximately $1.1 million. The adoption of Topic 842 did not have a material impact to our net income and related per share amounts.

Upon adoption of Topic 842, lessees and lessors are required to apply a modified retrospective transition approach. Reporting entities are permitted to choose one of two methods to recognize and measure leases within the scope of Topic 842:

• Apply Topic 842 to each lease that existed at the beginning of the earliest comparative period presented in the financial statements as well as leases that commenced after that date. Under this method, prior comparative periods presented are adjusted. For leases that commenced prior to the beginning of the earliest comparative period presented, a cumulative-effect adjustment is recognized at that date.

• Apply the guidance to each lease that had commenced as of the beginning of the reporting period in which the entity first applies the lease standard with a cumulative-effect adjustment as of that date. Prior comparative periods would not be adjusted under this method.

We have elected an optional transition method that allows entities to initially apply Topic 842 at January 1, 2019, the date of adoption, and to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. As the lessor, we have not assessed unamortized legal costs as part of the package of practical expedients, and we will not make any adjustment to retained earnings at the date of adoption to write off unamortized legal costs. We will continue to amortize unamortized legal costs as of December 31, 2018 over the life of the respective leases. We did not have a cumulative-effect adjustment as of the adoption date. Additionally, the optional transition method does allow us to not have to apply the new standard (including disclosure requirements) to comparative periods presented. Those periods can continue to be presented in accordance with prior generally accepted accounting principles.

Topic 842 requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases and operating leases. Based on our election of the package of practical expedients, our existing commercial leases, where we are the lessor, continue to be accounted for as operating leases under the new standard. However, Topic 842 changed certain requirements regarding the classification of leases that could result in us recognizing certain long-term leases entered into or modified after January 1, 2019 as sales-type leases or finance leases, as opposed to operating leases. We will continue to monitor our leases following the adoption date to ensure that they are classified in accordance with the new lease standards.

We elected a practical expedient which allows lessors to not separate non-lease components from the lease component when the timing and pattern of transfer for the lease components and non-lease components are the same and if the lease component is classified as an operating lease. As a result, we now present all rentals and reimbursements from tenants as a single line item, Rental, within the consolidated statements of operations and comprehensive income.

We review the collectability of charges under our tenant operating leases on a regular basis, taking into consideration changes in factors such as the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area where the property is located. Each tenant is included in one of several portfolios and an allowance is calculated using the calculation methodology for the respective portfolio. With the adoption of Topic 842, we will recognize an adjustment to rental revenue if we deem it probable that the receivable will not be collected. Prior to the adoption of Topic 842, we recognized an allowance for doubtful accounts and bad debt expense of the specific rents receivable. Our review of collectability under our operating leases includes any accrued rental revenues related to the straight-line method of reporting rental revenue.

In November 2016, the FASB issued guidance requiring that the statement of cash flows explain the change during the period in the total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within

F- 17

WHITESTONE REIT AND SUBSIDIARIES

Notes to Consolidated Financial Statements

December 31, 2019

those fiscal years. We adopted this guidance effective January 1, 2018, and we have reconciled cash and cash equivalents and restricted cash and restricted cash equivalents on a retrospective basis, whereas under the previous guidance, we reported restricted cash and restricted cash equivalents under cash flows from financing activities.

In January 2017, the FASB issued guidance clarifying the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or dispositions) of assets or businesses. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a prospective basis beginning January 1, 2018 and believe the majority of our future acquisitions will qualify as asset acquisitions and the associated transaction costs will be capitalized as opposed to expensed under previous guidance. For the year ending December 31, 2019, we capitalized $0.1 million in associated transaction costs.

In February 2017, the FASB issued guidance clarifying the scope of asset derecognition guidance, adding guidance for partial sales of nonfinancial assets and clarifying recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a modified retrospective basis beginning January 1, 2018 and have derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and have recognized the Company’s investment in Pillarstone OP under the equity method of accounting. The Company made an adjustment which decreased the Company’s accumulated deficit as of January 1, 2018 by $19.1 million. See Note 5 for further details.

3. MARKETABLE SECURITIES

In January 2018, we sold all of our remaining marketable securities and had no marketable securities as of December 31, 2019.

During the year ended December 31, 2018, available-for-sale securities were sold for total proceeds of $30,000. The gross realized losses on these sales totaled $20,000. For purposes of determining gross realized gains and losses, the cost of securities sold is based on specific identification.

4.  REAL ESTATE

As of December 31, 2019, we owned 58 commercial properties in the Austin, Chicago, Dallas-Fort Worth, Houston, Phoenix and San Antonio areas comprised of approximately 5.0 million square feet of gross leasable area (“GLA”). Five of the 58 commercial properties are land parcels held for future development.

Property Acquisitions. On December 6, 2019, we acquired Las Colinas Village, a property that meets our Community Centered Property^® strategy, for $34.8 million in cash and net prorations. Las Colinas Village, a 104,919 square foot property, was 86% leased at the time of purchase and is located in Irving, Texas. Revenue and net income attributable to Las Colinas of $0.3 million and $0.2 million, respectively, have been included in our results of operations for the year ended December 31, 2019.

On December 29, 2017, we acquired a 1.83 acre parcel of undeveloped land for $0.9 million in cash and net prorations. The undeveloped land parcel is the hard corner at our Eldorado Plaza property.

On May 26, 2017, we acquired BLVD Place, a property that meets our Community Centered Property^® strategy, for $158.0 million, including $80.0 million of asset level mortgage financing and $78.0 million in cash and net prorations. BLVD Place, a 216,944 square foot property, was 99% leased at the time of purchase and is located in Houston, Texas. Included in the purchase of BLVD Place is approximately 1.43 acres of developable land.

On May 3, 2017, we acquired Eldorado Plaza, a property that meets our Community Centered Property^® strategy, for $46.6 million in cash and net prorations. Eldorado Plaza, a 221,577 square foot property, was 96% leased at the time of purchase and is located in McKinney, Texas, a suburb of Dallas, Texas.

December 31, 2019

On November 15, 2019, we received a $0.8 million principal payment in connection with the sale of two retail buildings we completed on November 29, 2016. We recorded a gain on sale of $0.8 million. In 2016, we provided seller-financing for the retail buildings, Webster Pointe and Centre South, and deferred a $1.7 million gain until principal payments on the seller-financed loan are received. The purchaser of the retail buildings sold Webster Pointe on November 15, 2019 and paid the entire principal balance of the loan related to the property. We have not included the gain in discontinued operations as it did not meet the definition of discontinued operations at the date of the sale.

On April 24, 2019, we received a $0.7 million principal payment in connection with the sale of three office buildings we completed on December 31, 2014. We recorded a gain on sale of $0.7 million. In 2014, we provided seller-financing for the office buildings, Zeta, Royal Crest and Featherwood, and deferred a $2.5 million gain until principal payments on the seller-financed loan are received. The purchaser of the office buildings sold Zeta on April 24, 2019 and paid the entire principal balance of the loan related to the property. We have included the gain in discontinued operations as it did meet the definition of discontinued operations at the date of sale.     

Hurricane Harvey. In August 2017, Hurricane Harvey impacted the South Texas region, including Houston, Texas. The majority of our Houston properties incurred minor damage and as a result, we recorded approximately $0.5 million in Harvey related repairs in property operation and maintenance expense for the year ended December 31, 2017.

5. INVESTMENT IN REAL ESTATE PARTNERSHIP

On December 8, 2016, we, through our Operating Partnership, entered into a Contribution Agreement (the “Contribution Agreement”) with Pillarstone OP and Pillarstone Capital REIT (“Pillarstone REIT”) pursuant to which we contributed all of the equity interests in four of our wholly-owned subsidiaries: Whitestone CP Woodland Ph. 2, LLC, a Delaware limited liability company (“CP Woodland”); Whitestone Industrial-Office, LLC, a Texas limited liability company (“Industrial-Office”); Whitestone Offices, LLC, a Texas limited liability company (“Whitestone Offices”); and Whitestone Uptown Tower, LLC, a Delaware limited liability company (“Uptown Tower,” and together with CP Woodland, Industrial-Office and Whitestone Offices, the “Entities”) that own 14 non-core properties that do not fit our Community Centered Property^® strategy (the “Pillarstone Properties”), to Pillarstone OP for aggregate consideration of approximately $84 million, consisting of (1) approximately $18.1 million of Class A units representing limited partnership interests in Pillarstone OP (“Pillarstone OP Units”), issued at a price of $1.331 per Pillarstone OP Unit; and (2) the assumption of approximately $65.9 million of liabilities, consisting of (a) approximately $15.5 million of our liability under the 2018 Facility (as defined in Note 9); (b) an approximately $16.3 million promissory note of Uptown Tower under the Loan Agreement, dated as of September 26, 2013, between Uptown Tower, as borrower, and U.S. Bank, National Association, as successor to Morgan Stanley Mortgage Capital Holdings LLC, as lender; and (c) an approximately $34.1 million promissory note (the “Industrial-Office Promissory Note”) of Industrial-Office issued under the Loan Agreement, dated as of November 26, 2013 (the “Industrial-Office Loan Agreement”), between Industrial-Office, as borrower, and Jackson National Life Insurance Company, as lender (collectively, the “Contribution”).

In connection with the Contribution, (1) with respect to each Pillarstone Property (other than Uptown Tower), Whitestone TRS, Inc., a subsidiary of the Company (“Whitestone TRS”), entered into a Management Agreement with the Entity that owns such Pillarstone Property and (2) with respect to Uptown Tower, Whitestone TRS entered into a Management Agreement with Pillarstone OP (collectively, the “Management Agreements”). Pursuant to the Management Agreements with respect to each Pillarstone Property (other than Uptown Tower), Whitestone TRS agreed to provide certain property management, leasing and day-to-day advisory and administrative services to such Pillarstone Property in exchange for (x) a monthly property management fee equal to 5.0% of the monthly revenues of such Pillarstone Property and (y) a monthly asset management fee equal to 0.125% of GAV (as defined in each Management Agreement as, generally, the purchase price of the respective Pillarstone Property based upon the purchase price allocations determined pursuant to the Contribution Agreement, excluding all indebtedness, liabilities or claims of any nature) of such Pillarstone Property. Pursuant to the Management Agreement with respect to Uptown Tower, Whitestone TRS agreed to provide certain property management, leasing and day-to-day advisory and administrative services to Pillarstone OP in exchange for (x) a monthly property management fee equal to 3.0% of the monthly revenues of Uptown Tower and (y) a monthly asset management fee equal to 0.125% of GAV of Uptown Tower. The initial term of each Management Agreement expired on December 31, 2017, after which each Management Agreement became automatically renewable on a month to month basis; provided that each Management Agreement can be

terminated by either party thereto upon not less than thirty days’ prior written notice to the other party. None of the Management Agreements had been terminated as of December 31, 2019.

In connection with the Contribution, on December 8, 2016, the Operating Partnership entered into a Tax Protection Agreement with Pillarstone REIT and Pillarstone OP pursuant to which Pillarstone OP agreed to indemnify the Operating Partnership for certain tax liabilities resulting from its recognition of income or gain prior to December 8, 2021 if such liabilities result from a transaction involving a direct or indirect taxable disposition of all or a portion of the Pillarstone Properties or if Pillarstone OP fails to maintain and allocate to the Operating Partnership for taxation purposes minimum levels of liabilities as specified in the Tax Protection Agreement, the result of which causes such recognition of income or gain and the Company incurs taxes that must be paid to maintain its REIT status for federal income tax purposes.

As of December 31, 2019, we owned approximately 81.4% of the total outstanding units of Pillarstone OP. Additionally, certain of our officers and trustees serve as officers and trustees of Pillarstone REIT. In connection with the Contribution, in December 2016, we determined that we were the primary beneficiary of Pillarstone OP, through our power to direct the activities of Pillarstone OP, additional working capital required by Pillarstone OP under an OP Unit purchase agreement and our obligation to absorb losses and receive benefits based on our ownership percentage. Accordingly, we accounted for Pillarstone OP as a VIE and fully consolidated it in our consolidated financial statements for the year ended December 31, 2016 and in the subsequent periods.

In November 2017, we received a comment letter from the Staff of the Division of Corporation Finance of the SEC (the “Staff”) relating to our Annual Report on Form 10-K for the year ended December 31, 2016. In their letter, the Staff requested that we provide them with an analysis to support our determination that Pillarstone OP is a VIE of which we are the primary beneficiary and that Pillarstone OP should be consolidated in our financial statements in accordance with GAAP. In response to the Staff’s comment, we provided the Staff with our analysis of our accounting and financial reporting obligations relating to our interest in Pillarstone OP. After communicating our analysis and conclusions to the Staff and responding to additional questions from the Staff relating to this matter, the Staff did not object to or otherwise take exception to our initial determinations at the time of the consummation of the Contribution in December 2016 but provided a verbal reminder that the determination of the primary beneficiary of a VIE should be continually reassessed, noting that the initial terms of the Management Agreements expired in December 2017, and suggesting that we consider pre-clearing future accounting treatment of Pillarstone OP with the Staff of the Office of the Chief Accountant (“OCA”).

In connection with the preparation and review of the Company’s financial statements for the quarter ended March 31, 2018, the Company concluded, after consultation with the Company’s outside advisors, that it would be prudent to seek the pre-clearance from the Staff of the SEC’s Office of the Chief Accountant (“OCA”) of the proposed treatment of Pillarstone OP in the Company’s financial statements for such quarter. Accordingly, in April 2018, the Company submitted a letter to the OCA seeking their concurrence with the Company’s determinations that it maintained its status as the primary beneficiary of Pillarstone OP and, accordingly, should continue to consolidate Pillarstone OP in its financial statements for the quarter ended March 31, 2018 in accordance with GAAP. After further correspondence, including telephonic meetings between the Company, its advisors and the OCA, the OCA informed the Company that it objected to the conclusions that the Company was the primary beneficiary of Pillarstone OP and was required to consolidate it in the Company’s financial statements since the Contribution in December 2016 and during the subsequent periods.

After consideration of the OCA’s objection to the Company’s original accounting, the Company determined that the correct accounting treatment was to apply certain industry specific accounting guidance applicable to real estate transactions, ASC 360-20, the profit sharing method, which required the Company to continue to recognize the underlying assets and liabilities associated with the Contribution in the Company’s financial statements, and revised its accounting treatment accordingly. Management evaluated the quantitative and qualitative materiality of the errors and concluded that the difference between applying ASC 360-20 and the consolidation of Pillarstone OP under the VIE guidance was not material to the financial statements of any period presented through December 31, 2017. As a result, the Company elected to correct them in future financial statements, beginning with the consolidated financial statements as and for the period ended June 30, 2018 and in the accompanying prior period consolidated financial statements included in the Company’s Quarterly Report on Form 10-Q for the period ended June 30, 2018.

On January 1, 2018, the Company adopted ASU 2014-09 (“Topic 606”), as subsequently amended, using the modified retrospective method and applied Topic 606 to those contracts that were not completed as of January 1, 2018. Topic 606 added

a new section, ASC 610, “Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets,” which effectively superseded industry specific accounting guidance applicable to real estate transactions.

As a result of the adoption of Topic 606 and ASC 610, the Company derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and recognized the Company’s investment in Pillarstone OP under the equity method for the periods after December 31, 2017.

Included in 2019 equity in earnings from real estate partnership is a $13.8 million gain related to this sale.

On December 27, 2018, Pillarstone OP, through an indirect wholly owned subsidiary, Whitestone Industrial-Office, LLC, sold a portfolio of three properties in Houston, Texas to an unaffiliated third party for $15.8 million in cash.

8.  LEASES

Effective January 1, 2019, we adopted the new lease accounting guidance in Topic 842. As the lessee and lessor, we have elected the package of practical expedients permitted in Topic 842. See Note 2 for additional disclosure on Topic 842.

As a Lessor. All leases on our properties are classified as noncancelable operating leases, and the related rental income is recognized on a straight-line basis over the terms of the related leases. Differences between rental income earned and amounts due per the respective lease agreements are capitalized or charged, as applicable, to accrued rents and accounts receivable. Percentage rents are recognized as rental income when the thresholds upon which they are based have been met.  Recoveries from tenants for taxes, insurance, and other operating expenses are recognized as revenues in the period the corresponding costs are incurred. We combine lease and nonlease components in lease contracts, which includes combining base rent, recoveries, and percentage rents into a single line item, Rental, within the consolidated statements of operations and comprehensive income.

A summary of minimum future rents to be received (exclusive of renewals, tenant reimbursements, contingent rents, and collectability adjustments under Topic 842) under noncancelable operating leases in existence as of December 31, 2019 is as follows (in thousands):

Years Ended December 31,	Minimum Future Rents(1)
2020	$	83,552
2021	72,507
2022	60,766
2023	48,812
2024	36,988
Thereafter	110,496
Total	$	413,121

⁽¹⁾ These amounts do not reflect future rental revenues from the renewal or replacement of existing leases and exclude reimbursements of operating expenses and rental increases that are not fixed.

As a Lessee. We have office space, automobile, and office machine leases, which qualify as operating leases, with remaining lease terms of one to four years.

The following table summarizes the fixed, future minimum rental payments, excluding variable costs, which are discounted by our weighted average incremental borrowing rates to calculate the lease liabilities for our operating leases in existence as of December 31, 2019 in which we are the lessee (in thousands):

Years Ended December 31,	Minimum Future Rents
2020	$	919
2021	412
2022	50
2023	4
Total undiscounted rental payments	1,385
Less imputed interest	54
Total lease liabilities	$	1,331

For the year ended December 31, 2019, the total lease costs were $952,000. The weighted average remaining lease term for our operating leases was 1.7 years at December 31, 2019. We do not include renewal options in the lease term for calculating the lease liability unless we are reasonably certain we will exercise the option or the lessor has the sole ability to exercise the option. The weighted average incremental borrowing rate was 4.5% at December 31, 2019.

December 31, 2019

LIBOR is expected to be discontinued after 2021. A number of our current debt agreements have an interest rate tied to LIBOR. Some of these agreements provide procedures for determining an alternative base rate in the event that LIBOR is discontinued, but not all do so. Regardless, there can be no assurances as to what alternative base rates may be and whether such base rate will be more or less favorable than LIBOR and any other unforeseen impacts of the potential discontinuation of LIBOR. The Company intends to monitor the developments with respect to the potential phasing out of LIBOR after 2021 and work with its lenders to ensure any transition away from LIBOR will have minimal impact on its financial condition, but can provide no assurances regarding the impact of the discontinuation of LIBOR.

On March 22, 2019, we, through our Operating Partnership, entered into a Note Purchase and Guarantee Agreement (the “Note Agreement”) together with certain subsidiary guarantors as initial guarantor parties thereto (the “Subsidiary Guarantors”) and The Prudential Insurance Company of America and the various other purchasers named therein (collectively, the “Purchasers”) providing for the issuance and sale of $100 million of senior unsecured notes of the Operating Partnership, of which (i) $50 million are designated as 5.09% Series A Senior Notes due March 22, 2029 (the “Series A Notes”) and (ii) $50 million are designated as 5.17% Series B Senior Notes due March 22, 2029 (the “Series B Notes” and, together with the Series A Notes, the “Notes”) pursuant to a private placement that closed on March 22, 2019 (the “Private Placement”). Obligations under the Notes are unconditionally guaranteed by the Company and by the Subsidiary Guarantors.

The principal of the Series A Notes will begin to amortize on March 22, 2023 with annual principal payments of approximately $7.1 million. The principal of the Series B Notes will begin to amortize on March 22, 2025 with annual principal payments of $10.0 million. The Notes will pay interest quarterly on the 22nd day of March, June, September and December in each year until maturity.

The Operating Partnership may prepay at any time all, or from time to time part of, the Notes, in an amount not less than $1,000,000 in the case of a partial prepayment, at 100% of the principal amount so prepaid, plus a make-whole amount. The make-whole amount is equal to the excess, if any, of the discounted value of the remaining scheduled payments with respect to the Notes being prepaid over the aggregate principal amount of such Notes (as described in the Note Agreement). In addition, in connection with a Change of Control (as defined in the Note Purchase Agreement), the Operating Partnership is required to offer to prepay the Notes at 100% of the principal amount plus accrued and unpaid interest thereon.

The Note Agreement contains representations, warranties, covenants, terms and conditions customary for transactions of this type and substantially similar to the Operating Partnership’s existing senior revolving credit facility, including limitations on liens, incurrence of investments, acquisitions, loans and advances and restrictions on dividends and certain other restricted payments. In addition, the Note Agreement contains certain financial covenants substantially similar to the Operating Partnership’s existing senior revolving credit facility, including the following:

• maximum total indebtedness to total asset value ratio of 0.60 to 1.00;

• maximum secured debt to total asset value ratio of 0.40 to 1.00;

• minimum EBITDA (earnings before interest, taxes, depreciation, amortization or extraordinary items) to fixed charges ratio of 1.50 to 1.00;

• maximum other recourse debt to total asset value ratio of 0.15 to 1.00; and

• maintenance of a minimum tangible net worth (adjusted for accumulated depreciation and amortization) of $372 million plus 75% of the net proceeds from additional equity offerings (as defined therein).

In addition, the Note Agreement contains a financial covenant requiring that maximum unsecured debt not exceed the lesser of (i) an amount equal to 60% of the aggregate unencumbered asset value and (ii) the debt service coverage amount (as described in the Note Agreement). That covenant is substantially similar to the borrowing base concept contained in the Operating Partnership’s existing senior revolving credit facility.

The Note Agreement also contains default provisions, including defaults for non-payment, breach of representations and warranties, insolvency, non-performance of covenants, cross-defaults with other indebtedness and guarantor defaults. The occurrence of an event of default under the Note Agreement could result in the Purchasers accelerating the payment of all

obligations under the Notes. The financial and restrictive covenants and default provisions in the Note Agreement are substantially similar to those contained in the Operating Partnership’s existing credit facility.

Net proceeds from the Private Placement were used to refinance existing indebtedness. The Notes have not been and will not be registered under the Securities Act of 1933, as amended (the “Securities Act”), and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act. The Notes were sold in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act.

On January 31, 2019, we, through our Operating Partnership, entered into an unsecured credit facility (the “2019 Facility”) with the lenders party thereto, Bank of Montreal, as administrative agent (the “Agent”), SunTrust Robinson Humphrey, as syndication agent, and BMO Capital Markets Corp., U.S. Bank National Association, SunTrust Robinson Humphrey and Regions Capital Markets, as co-lead arrangers and joint book runners. The 2019 Facility amended and restated the 2018 Facility (as defined below).

The 2019 Facility is comprised of the following three tranches:

• $250.0 million unsecured revolving credit facility with a maturity date of January 1, 2023 (the “2019 Revolver”);

• $165.0 million unsecured term loan with a maturity date of January 31, 2024 (“Term Loan A”); and

• $100.0 million unsecured term loan with a maturity date of October 30, 2022 (“Term Loan B” and together with Term Loan A, the “2019 Term Loans”).

Borrowings under the 2019 Facility accrue interest (at the Operating Partnership's option) at a Base Rate or an Adjusted LIBOR plus an applicable margin based upon our then existing leverage. As of December 31, 2019, the interest rate on the 2019 Revolver was 3.35%. The applicable margin for Adjusted LIBOR borrowings ranges from 1.40% to 1.90% for the 2019 Revolver and 1.35% to 1.90% for the 2019 Term Loans. Base Rate means the higher of: (a) the Agent’s prime commercial rate, (b) the sum of (i) the average rate quoted by the Agent by two or more federal funds brokers selected by the Agent for sale to the Agent at face value of federal funds in the secondary market in an amount equal or comparable to the principal amount for which such rate is being determined, plus (ii) 1/2 of 1.00%, and (c) the LIBOR rate for such day plus 1.00%. Adjusted LIBOR means LIBOR divided by one minus the Eurodollar Reserve Percentage. The Eurodollar Reserve Percentage means the maximum reserve percentage at which reserves are imposed by the Board of Governors of the Federal Reserve System on eurocurrency liabilities. Pursuant to the 2019 Facility, in the event of certain circumstances that result in the unavailability of LIBOR, including but not limited to LIBOR no longer being a widely recognized benchmark rate for newly originated dollar loans in the U.S. market, the Operating Partnership and the Agent will establish an alternate interest rate to LIBOR giving due consideration to prevailing market conventions and will amend the 2019 Facility to give effect to such alternate interest rate.

The 2019 Facility includes an accordion feature that will allow the Operating Partnership to increase the borrowing capacity by $200.0 million, upon the satisfaction of certain conditions. As of December 31, 2019, $374.5 million was drawn on the 2019 Facility and our unused borrowing capacity was $140.5 million, assuming that we use the proceeds of the 2019 Facility to acquire properties, or to repay debt on properties, that are eligible to be included in the unsecured borrowing base. The Company used $446.2 million of proceeds from the 2019 Facility to repay amounts outstanding under the 2018 Facility and intends to use the remaining proceeds from the 2019 Facility for general corporate purposes, including property acquisitions, debt repayment, capital expenditures, the expansion, redevelopment and re-tenanting of properties in its portfolio and working capital.

The Company, each direct and indirect material subsidiary of the Operating Partnership and any other subsidiary of the Operating Partnership that is a guarantor under any unsecured ratable debt will serve as a guarantor for funds borrowed by the Operating Partnership under the 2019 Facility. The 2019 Facility contains customary terms and conditions, including, without limitation, customary representations and warranties and affirmative and negative covenants including, without limitation, information reporting requirements, limitations on investments, acquisitions, loans and advances, mergers, consolidations and sales, incurrence of liens, dividends and restricted payments. In addition, the 2019 Facility contains certain financial covenants including the following:

December 31, 2019

• maximum total indebtedness to total asset value ratio of 0.60 to 1.00;

• maximum secured debt to total asset value ratio of 0.40 to 1.00;

• minimum EBITDA (earnings before interest, taxes, depreciation, amortization or extraordinary items) to fixed charges ratio of 1.50 to 1.00;

• maximum other recourse debt to total asset value ratio of 0.15 to 1.00; and

• maintenance of a minimum tangible net worth (adjusted for accumulated depreciation and amortization) of $372 million plus 75% of the net proceeds from additional equity offerings (as defined therein).

We serve as the guarantor for funds borrowed by the Operating Partnership under the 2019 Facility. The 2019 Facility contains customary terms and conditions, including, without limitation, affirmative and negative covenants such as information reporting requirements, maximum secured indebtedness to total asset value, minimum EBITDA (earnings before interest, taxes, depreciation, amortization or extraordinary items) to fixed charges, and maintenance of a minimum net worth. The 2019 Facility also contains customary events of default with customary notice and cure, including, without limitation, nonpayment, breach of covenant, misrepresentation of representations and warranties in a material respect, cross-default to other major indebtedness, change of control, bankruptcy and loss of REIT tax status.

On November 7, 2014, we, through our Operating Partnership, entered into an unsecured revolving credit facility (the “2014 Facility”) with the lenders party thereto, with BMO Capital Markets Corp., Wells Fargo Securities, LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and U.S. Bank, National Association, as co-lead arrangers and joint book runners, and Bank of Montreal, as administrative agent (the “Agent”). The 2014 Facility amended and restated our previous unsecured revolving credit facility. On October 30, 2015, we, through our Operating Partnership, entered into the First Amendment to the 2014 Facility (the “First Amendment”) with the guarantors party thereto, the lenders party thereto and the Agent. We refer to the 2014 Facility, as amended by the First Amendment, as the “2018 Facility.”

Pursuant to the First Amendment, the Company made the following amendments to the 2014 Facility:

• extended the maturity date of the $300 million unsecured revolving credit facility under the 2014 Facility (the “2018 Revolver”) to October 30, 2019 from November 7, 2018;

• converted $100 million of outstanding borrowings under the Revolver to a new $100 million unsecured term loan under the 2014 Facility (“Term Loan 3”) with a maturity date of October 30, 2022;

• extended the maturity date of the first $50 million unsecured term loan under the 2014 Facility (“Term Loan 1”) to October 30, 2020 from February 17, 2017; and

• extended the maturity date of the second $50 million unsecured term loan under the 2014 Facility (“Term Loan 2” and together with Term Loan 1 and Term Loan 3, the “2018 Term Loans”) to January 29, 2021 from November 7, 2019.

Borrowings under the 2018 Facility accrued interest (at the Operating Partnership's option) at a Base Rate or an Adjusted LIBOR plus an applicable margin based upon our then existing leverage. The applicable margin for Adjusted LIBOR borrowings ranged from 1.40% to 1.95% for the 2018 Revolver and 1.35% to 2.25% for the 2018 Term Loans. Base Rate means the higher of: (a) the Agent’s prime commercial rate, (b) the sum of (i) the average rate quoted by the Agent by two or more federal funds brokers selected by the Agent for sale to the Agent at face value of federal funds in the secondary market in an amount equal or comparable to the principal amount for which such rate is being determined, plus (ii) 1/2 of 1.00%, and (c) the LIBOR rate for such day plus 1.00%. Adjusted LIBOR means LIBOR divided by one minus the Eurodollar Reserve Percentage. The Eurodollar Reserve Percentage means the maximum reserve percentage at which reserves are imposed by the Board of Governors of the Federal Reserve System on eurocurrency liabilities.

Proceeds from the 2018 Facility were used for general corporate purposes, including property acquisitions, debt repayment, capital expenditures, the expansion, redevelopment and re-tenanting of properties in our portfolio and working capital.

On May 26, 2017, we, through our subsidiary, Whitestone BLVD Place LLC, a Delaware limited liability company, issued a $80.0 million promissory note to American General Life Insurance Company (the “BLVD Note”). The BLVD Note has a fixed interest rate of 3.72% and a maturity date of June 1, 2027. Proceeds from the BLVD Note were used to fund a portion of the purchase price of the acquisition of BLVD Place.

As of December 31, 2019, our $171.4 million in secured debt was collateralized by eight properties with a carrying value of $270.4 million.  Our loans contain restrictions that would require the payment of prepayment penalties for the acceleration of outstanding debt and are secured by deeds of trust on certain of our properties and by assignment of the rents and leases associated with those properties.  In 2018, we were not in compliance with respect to the tangible Net Worth covenant as defined in the 2018 Facility and had received two waivers in 2018. Had we been unable to obtain a waiver or other suitable relief from the lenders under the 2018 Facility, an Event of Default (as defined in the 2018 Facility) would have occurred, permitting the lenders holding a majority of the commitments under the 2018 Facility to, among other things, accelerate the outstanding indebtedness, which would make it immediately due and payable. The 2019 Facility and the Notes contain a similar tangible Net Worth covenant that resets at a new threshold and changes the definition of Net Worth to add back accumulated depreciation. However, we can make no assurances that we will be in compliance with these covenants or other covenants under the 2019 Facility or the Notes in future periods or, if we are not in compliance, that we will be able to obtain a waiver. As of December 31, 2019, we were in compliance with all loan covenants.

Scheduled maturities of our outstanding debt as of December 31, 2019 were as follows (in thousands):

11.  EARNINGS PER SHARE

Basic earnings per share for our common shareholders is calculated by dividing income from continuing operations excluding amounts attributable to unvested restricted shares and the net income attributable to non-controlling interests by our weighted-average common shares outstanding during the period.  Diluted earnings per share is computed by dividing the net income attributable to common shareholders excluding amounts attributable to unvested restricted shares and the net income attributable to non-controlling interests by the weighted-average number of common shares including any dilutive unvested restricted shares.

Certain of our performance-based restricted common shares are considered participating securities, which require the use of the two-class method for the computation of basic and diluted earnings per share.   During the years ended December 31, 2019, 2018 and 2017, 924,314, 1,011,268 and 1,088,292 OP units, respectively, were excluded from the calculation of diluted earnings per share because their effect would be anti-dilutive.

For the years ended December 31, 2019, 2018 and 2017, distributions of $41,000, $317,000 and $472,000, respectively, were made to the holders of certain restricted common shares, $0, $16,000, and $16,000 of which were charged against earnings, annually for the years ended December 31, 2019, 2018, and 2017, respectively.  See Note 15 for information related to restricted common shares under the 2008 Plan.

12.  FEDERAL INCOME TAXES

Federal income taxes are not provided because we intend to and believe we qualify as a REIT under the provisions of the Code and because we have distributed and intend to continue to distribute all of our taxable income to our shareholders.  Our shareholders include their proportionate taxable income in their individual tax returns.  As a REIT, we must distribute at least 90% of our real estate investment trust taxable income to our shareholders and meet certain income sources and investment restriction requirements.  In addition, REITs are subject to a number of organizational and operational requirements.  If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax on our taxable income at regular corporate tax rates.

Taxable income differs from net income for financial reporting purposes principally due to differences in the timing of recognition of interest, real estate taxes, depreciation and rental revenue.

The Contribution was unanimously approved and recommended by a special committee of independent Trustees of the Company. See Note 5 for additional disclosure on the Contribution.

Pillarstone OP. For the periods prior to January 1, 2018, Pillarstone OP was accounted for under the profit-sharing method, and related party transactions between the Company and Pillarstone OP were eliminated. As a result of the adoption of Topic 606 and ASC 610 as of January 1, 2018, the Company derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and recognized the Company’s investment in Pillarstone OP under the equity method.

Equity Offerings

On May 31, 2019, we entered into nine equity distribution agreements for an at-the-market equity distribution program (the “2019 equity distribution agreements”) providing for the issuance and sale of up to an aggregate of $100 million of the Company’s common shares pursuant to our Registration Statement on Form S-3 (File No. 333-225007). Actual sales will depend on a variety of factors determined by us from time to time, including (among others) market conditions, the trading price of our common shares, capital needs and our determinations of the appropriate sources of funding for us, and were made in transactions that will be deemed to be “at-the-market” offerings as defined in Rule 415 under the Securities Act. We have no obligation to sell any of our common shares and can at any time suspend offers under the 2019 equity distribution agreements or terminate the 2019 equity distribution agreements. For the year ended December 31, 2019, we sold 1,612,389 common shares under the 2019 equity distribution agreements, with net proceeds to us of approximately $21.2 million. In connection with such sales, we paid compensation of approximately $324,000 to the sales agents.

On April 25, 2017, we completed the sale of 8,018,500 common shares, including 1,018,500 common shares purchased by the underwriters upon exercise of their option to purchase additional common shares, at a public offering price per share of $13.00 (the “April 2017 Offering”). Total net proceeds from the April 2017 Offering, after deducting offering expenses, were approximately $99.9 million, which we contributed to the Operating Partnership in exchange for OP units. The Operating Partnership used the net proceeds from the April 2017 Offering to repay a portion of the 2018 Facility and for general corporate purposes, including funding a portion of the purchase price of BLVD Place and Eldorado Plaza.

On June 4, 2015, we entered into nine amended and restated equity distribution agreements (the “2015 equity distribution agreements”) for an at-the-market distribution program. Pursuant to the terms and conditions of the 2015 equity distribution agreements, we could issue and sell up to an aggregate of $50 million of our common shares pursuant to our Registration Statement on Form S-3 (File No. 333-203727), which expired on April 29, 2018. Actual sales depended on a variety of factors determined by us from time to time, including (among others) market conditions, the trading price of our common shares, capital needs and our determinations of the appropriate sources of funding for us, and were made in transactions that will be deemed to be “at-the-market” offerings as defined in Rule 415 under the Securities Act. We had no obligation to sell any of our common shares, and could at any time suspend offers under the 2015 equity distribution agreements or terminate the 2015 equity distribution agreements. For the year ended December 31, 2019 and 2018, we did not sell any common shares under the 2015 equity distribution agreements. For the year ended December 31, 2017, we sold 1,324,038 common shares under the 2015 equity distribution agreements, with net proceeds to us of approximately $18.6 million. In connection with such sales, we paid compensation of approximately $0.3 million to the sales agents.

Operating Partnership Units

Substantially all of our business is conducted through the Operating Partnership.  We are the sole general partner of the Operating Partnership.  As of December 31, 2019, we owned a 97.9% interest in the Operating Partnership.

Limited partners in the Operating Partnership holding OP units have the right to redeem their OP units for cash or, at our option, common shares at a ratio of one OP unit for one common share.  Distributions to OP unit holders are paid at the same rate per unit as distributions per share to Whitestone common shares.  As of December 31, 2019 and 2018, there were 42,279,849 and 40,585,688 OP units outstanding, respectively.  We owned 41,371,277 and 39,657,207 OP units as of December 31, 2019 and 2018, respectively. The balance of the OP units is owned by third parties, including certain trustees.  Our weighted-average share ownership in the Operating Partnership was approximately 97.7%, 97.5% and 97.0% for the years ended December 31, 2019, 2018 and 2017, respectively. For the years ended December 31, 2019 and 2018, 19,909 and 155,100 OP units, respectively, were redeemed for an equal number of common shares.

15.  INCENTIVE SHARE PLAN

On July 29, 2008, our shareholders approved the 2008 Plan. On December 22, 2010, our board of trustees amended the 2008 Plan to allow for awards in or related to Class B common shares pursuant to the 2008 Plan. On June 27, 2012, our Class B common shares were redesignated as “common shares.” The 2008 Plan, as amended, provides that awards may be made with respect to common shares of Whitestone or OP units, which may be redeemed for cash or, at our option, common shares of Whitestone. The maximum aggregate number of common shares that may be issued under the 2008 Plan is increased upon each issuance of common shares by Whitestone so that at any time the maximum number of common shares that may be issued under the 2008 Plan shall equal 12.5% of the aggregate number of common shares of Whitestone and OP units issued and outstanding (other than shares and/or units issued to or held by Whitestone).

The Compensation Committee of our board of trustees administers the 2008 Plan, except with respect to awards to non-employee trustees, for which the 2008 Plan is administered by our board of trustees.  The Compensation Committee is authorized to grant share options, including both incentive share options and non-qualified share options, as well as share appreciation rights, either with or without a related option. The Compensation Committee is also authorized to grant restricted common shares, restricted common share units, performance awards and other share-based awards. 

On April 2, 2014, the Compensation Committee approved the modification of the vesting provisions with respect to awards of an aggregate of 633,704 restricted common shares and restricted common share units for certain of our employees. The modified time-based shares vested annually in three equal installments. The modified performance-based restricted common shares and restricted common share units were modified to include performance-based vesting based on achievement of certain absolute financial goals, as well as one to two years of time-based vesting post achievement of financial goals. Continued employment is required through the applicable vesting date. Additionally, 2,049,116 restricted performance-based common share units were granted with the same vesting conditions as the modified performance-based grants described above. The performance targets were not met prior to December 31, 2018, any unvested performance-based restricted common shares and restricted common share units were forfeited due to the performance targets not being met.

The Compensation Committee approved the grant of an aggregate of 320,000 and 143,000 time-based restricted common share units on June 30, 2016 and 2015, respectively, to James C. Mastandrea and David K. Holeman.

On September 6, 2017, the Compensation Committee approved the grant of an aggregate of 267,783 performance-based restricted common share units under the 2008 Plan with market-based vesting conditions (the “TSR Units”) to certain of our employees. Vesting is contingent upon achieving Total Shareholder Return relative to the peer group defined in the TSR Unit award agreements over a three-year performance period. At the end of the performance period, the number of common shares awarded for each vested TSR Unit will be 200% based on the Company’s ranking in the peer group (the “TSR Peer Group Ranking”). Continued employment is required through the vesting date. The grant date fair value for each TSR Unit of $12.37 was determined using the Monte Carlo simulation method and is being recognized as share-based compensation expense ratably from the September 30, 2017 grant date to the end of the performance period, December 31, 2019. The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the award grant and calculates the fair value of the award. Expected volatilities utilized in the model were estimated using a historical period consistent with the performance period of approximately three years. The risk-free interest rate was based on the United States Treasury rate for a term commensurate with the expected life of the grant. On January 1, 2020, the remaining unvested 247,978 TSR units that were granted on September 6, 2017 vested at 200% achievement into 495,956 common shares.

On September 6, 2017, the Compensation Committee approved the grant of an aggregate of 965,000 performance-based restricted common share units under the 2008 Plan which only vest immediately prior to the consummation of a Change in Control (as defined in the 2008 Plan) that occurs on or before September 30, 2024 (the “CIC Units”) to certain of our employees. Continued employment is required through the vesting date. If a Change in Control does not occur on or before September 30, 2024, the CIC Units shall be immediately forfeited. The Company considers a Change in Control on or before September 30, 2024 to be improbable, and no expense has been recognized for the CIC Units. If a Change in Control occurs, any outstanding CIC Units would be expensed immediately on the date of the Change in Control using the grant date fair value. The grant date fair value for each CIC Unit of $13.05 was determined based on the Company’s closing share price on the grant date.

At the Company’s annual meeting of shareholders on May 11, 2017, its shareholders voted to approve the 2018 Long-Term Equity Incentive Ownership Plan (the “2018 Plan”). The 2018 Plan provides for the issuance of up to 3,433,831 common shares and OP units pursuant to awards under the 2018 Plan. The 2018 Plan became effective on July 30, 2018, which was the day after the 2008 Plan expired.

The Compensation Committee administers the 2018 Plan, except with respect to awards to non-employee trustees, for which the 2018 Plan is administered by the Board of Trustees.  The Compensation Committee is authorized to grant share options, including both incentive share options and non-qualified share options, as well as share appreciation rights, either with or without a related option. The Compensation Committee is also authorized to grant restricted common shares, restricted common share units, performance awards and other share-based awards

    On December 1, 2018, the Compensation Committee approved the grant of an aggregate of 229,684 TSR Units under the 2018 Plan to certain of our employees. Vesting is contingent upon achieving Total Shareholder Return relative to the peer group defined in the TSR Unit award agreements over a three-year performance period. At the end of the performance period, the number of common shares awarded for each vested TSR Unit will vary from 0% to 200% depending on the Company’s TSR Peer Group Ranking. Continued employment is required through the vesting date. The grant date fair value for each TSR Unit of $14.89 was determined using the Monte Carlo simulation method and is being recognized as share-based compensation expense ratably from the December 1, 2018 grant date to the end of the performance period, December 31, 2020. The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the award grant and calculates the fair value of the award. Expected volatilities utilized in the model were estimated using a historical period consistent with the performance period of approximately three years. The risk-free interest rate was based on the United States Treasury rate for a term commensurate with the expected life of the grant.

On June 30, 2019, the Compensation Committee approved the grant of an aggregate of 405,417 TSR Units and 317,184 time-based restricted common share units under the 2018 Plan to certain of our employees. On September 30, 2019, the Compensation Committee approved the grant of 17,069 time-based restricted common share units under the 2018 Plan to certain of our employees. Vesting of the TSR Units is contingent upon achieving Total Shareholder Return relative to the peer group defined in the TSR Unit award agreements over a three-year performance period. At the end of the performance period, the number of common shares awarded for each vested TSR Unit will vary from 0% to 200% depending on the Company’s

TSR Peer Group Ranking. Continued employment is required through the vesting date. The grant date fair value for each TSR Unit of $8.22 was determined using the Monte Carlo simulation method and is being recognized as share-based compensation expense ratably from the June 30, 2019 grant date to the end of the performance period, December 31, 2021. The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the award grant and calculates the fair value of the award. Expected volatilities utilized in the model were estimated using a historical period consistent with the performance period of approximately three years. The risk-free interest rate was based on the United States Treasury rate for a term commensurate with the expected life of the grant. The time-based restricted common share units have a grant date fair value of $10.63 and $11.69 and vest annually in three equal installments for the June 30, 2019 and September 30, 2019 grants, respectively.

A summary of the share-based incentive plan activity as of and for the year ended December 31, 2019 is as follows:

	Shares		Weighted-Average Grant Date Fair Value (1)
Non-vested at January 1, 2019	1,923,382		$	12.41
Granted	762,630		9.46
Vested	(284,964	)	11.76
Forfeited	(61,116	)	12.62
Non-vested at December 31, 2019	2,339,932		$	11.52
Available for grant at December 31, 2019	1,792,528

⁽¹⁾  The fair value of the shares granted were determined based on observable market transactions occurring near the date of the grants.

A summary of our nonvested and vested shares activity for the years ended December 31, 2019, 2018 and 2017 is presented below:

	Shares Granted			Shares Vested
Year Ended	Non-Vested Shares Issued	Weighted-Average Grant-Date Fair Value		Vested Shares		Total Vest-Date Fair Value
						(in thousands)
Year Ended December 31, 2019	762,630	$	9.46	(284,964	)	$	3,352
Year Ended December 31, 2018	653,472	$	11.07	(560,126	)	$	7,978
Year Ended December 31, 2017	1,354,534	$	12.92	(881,710	)	$	12,829

Total compensation recognized in earnings for share-based payments for the years ended December 31, 2019, 2018 and 2017 was $6.5 million, $6.8 million and $10.4 million, respectively.

Based on our current financial projections, we expect 100% of the unvested awards, exclusive of 895,000 CIC Units, to vest over the next 33 months. As of December 31, 2019, there was approximately $4.2 million in unrecognized compensation cost related to outstanding non-vested TSR Units, which are expected to vest over a period of 24 months and approximately $4.2 million in unrecognized compensation cost related to outstanding non-vested time-based shares, which are expected to be recognized over a period of approximately 33 months beginning on January 1, 2020.

WHITESTONE REIT AND SUBSIDIARIES

December 31, 2019

We expect to record approximately $8.4 million in share-based compensation subsequent to the year ended December 31, 2019. The unrecognized share-based compensation cost is expected to vest over a weighted average period of 23 months. The dilutive impact of the performance-based shares will be included in the denominator of the earnings per share calculation beginning in the period that the performance conditions are expected to be met. The dilutive impact of the TSR Units is based on the Company’s TSR Peer Group Ranking as of the reporting date and weighted according to the number of days outstanding in the period. As of December 31, 2019, the TSR Peer Group Ranking called for 200%, 100%, and 50% attainment of the TSR Units granted in 2017, 2018, and 2019, respectively. The dilutive impact of the CIC Units is based on the probability of a Change in Control. Because the Company considers a Change in Control on or before September 30, 2024 to be improbable, no CIC Units are included in the Company’s dilutive shares.

16. GRANTS TO TRUSTEES

On December 12, 2019, each of our six independent trustees and one trustee emeritus were granted approximately 3,000 common shares, which vest immediately and are prorated based on date appointed. The 19,562 common shares granted to our trustees had a grant fair value of $13.54 per share. On December 12, 2019, two of our independent trustees each elected to receive a total of 3,398 common shares with a grant date fair value of $13.54 in lieu of cash for board fees. The fair value of the shares granted during the year ended December 31, 2019 was determined using quoted prices available on the date of grant.

On December 28, 2018, each of our six independent trustees and one trustee emeritus were granted 3,000 common shares, which vest immediately and are prorated based on date appointed. The 21,000 common shares granted to our trustees had a grant fair value of $12.42 per share. On December 28, 2018, two of our independent trustees each elected to receive a total of 4,186 common shares with a grant date fair value of $12.42 in lieu of cash for board fees. The fair value of the shares granted during the year ended December 31, 2018 was determined using quoted prices available on the date of grant.

On December 12, 2017, each of our six independent trustees and one trustee emeritus were granted approximately 3,000 common shares, which vest immediately and are prorated based on date appointed. The 16,281 common shares granted to our trustees had a grant fair value of $14.46 per share. On December 12, 2017, three of our independent trustees each elected to receive a total of 2,320 common shares with a grant date fair value of $14.46 in lieu of cash for board fees. The fair value of the shares granted during the year ended December 31, 2017 was determined using quoted prices available on the date of grant.

17.  COMMITMENTS AND CONTINGENCIES

We are subject to various legal proceedings and claims that arise in the ordinary course of business.  These matters are generally covered by insurance.  While the resolution of these matters cannot be predicted with certainty, management believes the final outcome of such matters will not have a material adverse effect on our financial position, results of operations, cash flows or liquidity.

On April 16, 2019, a purported shareholder of the Company filed a class action lawsuit in the United States District Court for the Southern District of Texas against the Company, James C. Mastandrea, and David K. Holeman, entitled Clark v. Whitestone REIT, et al., Case 4:19-cv-01379.  A second class action lawsuit was filed but was consolidated into the Clark case. The complaint alleges, among other things, that the Company and the individual defendants violated certain federal securities laws by making materially false and misleading statements in the Company’s Forms 10-Q for the first three quarterly periods of the year ended December 31, 2018 as a result of the accounting errors that required the restatement of our consolidated financial statements for the first three quarterly periods of the year ended December 31, 2018.  The purported class period runs from May 9, 2018 through February 27, 2019. The complaint sought, among other things, compensatory damages in an amount to be proven at trial, plus interest, attorneys’ fees, and costs.  In August 2019, the complainants in these purported class actions withdrew their claims, and the Court issued an order dismissing them with prejudice. On July 17, 2019, the Company received a demand letter from a purported shareholder containing allegations similar to those contained in the purported class actions. Subsequent to the dismissal of the purported class actions, in September 2019, counsel for the purported shareholder withdrew its demand.

On December 12, 2017, a property owner that owns a land parcel adjacent to a Whitestone property filed suit against Whitestone Pinnacle of Scottsdale - Phase II, LLC (“Whitestone Pinnacle”)alleging breach of contract and resulting in the delay of the construction of the their assisted living facility. In May 2019, the claimant amended their report of damages and seeks approximately $2.7 million in restitution from Whitestone Pinnacle. The Company intends to vigorously defend the matter as it believes that these claims are without merit and that it has substantial legal and factual defenses to the claims and allegations contained in the complaint. Based upon the present status of this matter, the Company does not believe it is probable that a loss will be incurred. Accordingly, the Company has not recorded a charge as a result of this action.

Exhibit 3.1.8

WHITESTONE REIT

ARTICLES OF AMENDMENT

THIS IS TO CERTIFY THAT:

FIRST: The declaration of trust (the “Declaration of Trust”) of Whitestone REIT, a Maryland real estate investment trust (the “Trust”), is hereby amended by deleting Section 5.2 of Article V in its entirety and inserting the following:

Section 5.2     Number and Classification. The number of Trustees (hereinafter the “Trustees”) is currently seven (7), but such number may hereafter be increased or decreased pursuant to the Bylaws. Notwithstanding the foregoing, if for any reason any or all of the Trustees cease to be Trustees, such event shall not terminate the Trust or affect the Declaration of Trust or the powers of the remaining Trustees.

The Trustees may increase the number of Trustees and fill any vacancy, whether resulting from an increase in the number of Trustees or otherwise, on the Board of Trustees in the manner provided in the Bylaws. Election of Trustees by shareholders shall require the vote and be in accordance with the procedures set forth in the Bylaws. It shall not be necessary to list in the Declaration of Trust the names and addresses of any Trustees hereinafter elected.

The Trustees (other than any Trustee elected solely by holders of one or more classes or series of Preferred Shares, as hereinafter defined) are currently classified, with respect to the terms for which they severally hold office, into three classes, as nearly equal in number as possible, such that at each annual meeting of shareholders, the successors to the class of Trustees whose term expires at such meeting are elected to hold office for a term expiring at the annual meeting of shareholders held in the third year following the year of their election and until their successors are duly elected and qualify.  The name of each of the current seven Trustees, his or her class and the year in which his or her current term shall expire at the annual meeting of shareholders and upon the election and qualification of his or her successor are:

Trustee	Class	Year in Which Term to Expire
Paul T. Lambert	I	2022
David F. Taylor	I	2022
Donald F. Keating	II	2020
Najeeb A. Khan	II	2020
Nandita V. Berry	III	2021
Jack L. Mahaffey	III	2021
James C. Mastandrea	III	2021

Commencing at the 2020 annual meeting of shareholders, the Trustees (other than any Trustee elected solely by holders of one or more classes or series of Preferred Shares) shall be elected as follows: (i) at the 2020 annual meeting of shareholders, each Trustee who shall be elected to succeed a Trustee with a term expiring at the 2020 annual meeting of shareholders and upon the election and qualification of his successor shall be elected annually and shall serve until the next annual meeting of shareholders and until his or her successor is duly elected and qualifies; (ii) at the 2021 annual meeting of shareholders, each

Trustee who shall be elected to succeed a Trustee with a term expiring at the 2021 annual meeting of shareholders (including, for the avoidance of doubt, those Trustees elected at the 2020 annual meeting of shareholders) and upon the election and qualification of his or her successor shall be elected annually and shall serve until the next annual meeting of shareholders and until his or her successor is duly elected and qualifies; and (iii) at and after the 2022 annual meeting of shareholders, the Trustees shall no longer be classified, with respect to the terms for which they severally hold office, and each Trustee (including, for the avoidance of doubt, those Trustees elected at the 2021 annual meeting of shareholders) shall be elected annually and shall serve until the next annual meeting of shareholders and until his or her successor is duly elected and qualifies.

SECOND: The amendment to the Declaration of Trust as set forth above has been duly advised by the Board of Trustees of the Trust and approved by the shareholders of the Trust as required by law.

THIRD: These Articles of Amendment shall be effective upon filing with the State Department of Assessments and Taxation of Maryland.

FOURTH: The undersigned acknowledges these Articles of Amendment to be the trust act of the Trust and as to all matters or facts required to be verified under oath, the undersigned acknowledges that to the best of his knowledge, information and belief, these matters and facts are true in all material respects and that this statement is made under the penalties for perjury.

[SIGNATURE PAGE FOLLOWS]

IN WITNESS WHEREOF, the Trust has caused these Articles of Amendment to be signed in its name and on its behalf by its Chairman and Chief Executive Officer and attested to by its Secretary on this 20^th day of May, 2019.

EX-4.1

DESCRIPTION OF REGISTRANT’S SECURITIES

REGISTERED PURSUANT TO SECTION 12 OF

THE SECURITIES EXCHANGE ACT OF 1934

The following is a brief description of the common shares Whitestone REIT (the “Company” or “we,” “us” or “our”), which are the Company’s only securities registered pursuant to Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). This description of the terms of our common shares does not purport to be complete and is subject to and qualified in its entirety by reference to the applicable provisions of Maryland law, and the full text of our Articles of Amendment and Restatement, as amended and supplemented (our “declaration of trust”) and our Amended and Restated Bylaws (our “bylaws”).

General

We are organized as a REIT under the laws of the state of Maryland. Rights of our shareholders are governed by Maryland law, including the statute governing real estate investment trusts (“REITs”) formed under the laws of that state, or the Maryland REIT Law, our declaration of trust and our bylaws. The following description of the terms of our shares is not complete but is a summary.

Authorized Shares

Our declaration of trust provides that we may issue up to 400,000,000 common shares of beneficial interest, $0.001 par value per share, and up to 50,000,000 preferred shares of beneficial interest, $0.001 par value per share. In addition, our board of trustees, without any action by our shareholders, may amend our declaration of trust from time to time to increase or decrease the aggregate number of shares or the number of shares of any class or series that we have authority to issue.

Pursuant to Maryland law and our declaration of trust, no shareholder will be liable for any debt, claim, demand, judgment or obligation of any kind of, against or with respect to us by reason of being a shareholder, nor shall any shareholder be subject to any personal liability whatsoever, in tort, contract or otherwise, to any person in connection with our property or affairs by reason of his being a shareholder.

Common Shares

Subject to the preferential rights of any other class or series of shares of beneficial interest and to the provisions of our declaration of trust regarding the restrictions on ownership and transfer of shares of beneficial interest, holders of our common shares are entitled to receive distributions when authorized by our board of trustees and declared by us out of assets legally available for the payment of distributions, and to share ratably in our assets legally available for distribution to our shareholders in the event of our liquidation, dissolution or winding up, after payment of or adequate provision for all of our known debts and liabilities. All of these rights are subject to the preferential rights of any other class or series of our shares and to the provisions of our declaration of trust regarding restrictions on ownership and transfer of our shares.

Subject to the provisions of our declaration of trust regarding restrictions on transfer and ownership of our shares, and except as may otherwise be specified in the terms of any class or series of common shares, each outstanding common share entitles the holder to one vote on all matters submitted to a vote of shareholders, including the election of trustees. There is no cumulative voting in the election of trustees, which means that the holders of our common shares entitled to cast a majority of all the votes entitled to be cast can elect all of the trustees then standing for election, and the holders of the remaining shares will not be able to elect any trustees.

Holders of our common shares have no preference, conversion, exchange, sinking fund or redemption rights, have no preemptive rights to subscribe for any of our securities and generally have no appraisal rights unless our board of trustees determines that appraisal rights apply, with respect to all or any classes or series of shares, to one or more transactions occurring after the date of such determination in connection with which shareholders would otherwise be entitled to exercise appraisal rights.

Power to Reclassify Our Shares

Our declaration of trust authorizes our board of trustees to classify and reclassify any of our unissued common shares and preferred shares into other classes or series of shares. Prior to issuance of classified or reclassified shares of each class or series, our board of trustees is required by Maryland law and by our declaration of trust to designate the class or series to distinguish it from all other classes and series of shares, specify the number of shares to be included in the class or series, and set the terms, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption for each class or series. Thus, our board of trustees could authorize the issuance of common or preferred shares with terms and conditions that could have the effect of delaying, deferring or preventing a transaction or a change in control that might involve a premium price for holders of our common shares or otherwise be in their best interest.

Power to Issue Additional Common Shares and Preferred Shares

Our board of trustees has the power, without shareholder approval, to amend our declaration of trust from time to time to increase the aggregate number of shares or the number of shares of any class or series that we have authority to issue, to issue additional common shares or preferred shares, and to classify or reclassify unissued common or preferred shares and thereafter to cause us to issue such classified or reclassified shares. These actions can be taken without shareholder approval, unless shareholder approval is required by applicable law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded.

Restrictions on Ownership and Transfer

In order for us to qualify as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”), our common shares must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of twelve months or during a proportionate part of a shorter taxable year. Also, not more than 50% of the value of our outstanding common shares may be owned, directly or indirectly, by five or fewer individuals (as defined in the Code to include certain entities such as qualified

pension plans) during the last half of a taxable year. These requirements do not apply to the first year for which an election to be a REIT is made.

Our declaration of trust contains restrictions on the number of our shares that a person may own. Unless otherwise exempted by the board of trustees (as described below), no person or persons acting as a group may acquire or hold, directly or indirectly, more than 9.8% (by value or by number of shares, whichever is more restrictive) of our outstanding common shares.

Our declaration of trust further prohibits (i) any person from owning our shares if that ownership would result in our being “closely held” under Section 856(h) of the Code or otherwise cause us to fail to qualify as a REIT and (ii) any person from transferring our shares if the transfer would result in our shares being beneficially owned by fewer than 100 persons. Any person who acquires or intends to acquire any of our shares that may violate any of these restrictions, or who is the intended transferee of our shares that are transferred to the trust for the charitable beneficiary, as described below, is required to give us immediate written notice or, in the case of a proposed or attempted transaction, 15 days prior written notice and provide us with such information as we may request in order to determine the effect of the transfer on our status as a REIT. The above restrictions will not apply if our board of trustees determines that it is no longer in our best interests to continue to qualify as a REIT.

Our board of trustees may, in its sole discretion, exempt, prospectively or retroactively, a person from the 9.8% ownership limits. However, the board of trustees may not exempt a person unless, among other information, such person submits to the board of trustees information satisfactory to the board of trustees, in its reasonable discretion, demonstrating that (i) such person is not an individual, (ii) no individual would be considered to beneficially own shares in excess of the 9.8% ownership limits by reason of the exemption of such person from the 9.8% ownership limits and (iii) the exemption of such person from the 9.8% ownership limits will not cause us to fail to qualify as a REIT. The person also must agree that any violation or attempted violation of these restrictions will result in the automatic transfer of the shares causing the violation to the trust for the charitable beneficiary, as described below. Our board of trustees may require a ruling from the Internal Revenue Service (“IRS”), or an opinion of counsel in order to determine or ensure our status as a REIT or that compliance is no longer required for REIT qualification.

Any attempted transfer of our shares that, if effective, would result in our shares being beneficially owned by fewer than 100 persons will be null and void, and the proposed transferee will not acquire any rights in the shares. Any attempted transfer of our shares that, if effective, would result in violation of the 9.8% ownership limits discussed above or in our being “closely held” under Section 856(h) of the Code or otherwise failing to qualify as a REIT will cause the number of shares causing the violation (rounded to the nearest whole share) to be automatically transferred to a trust for the exclusive benefit of one or more charitable beneficiaries, and the proposed transferee will not acquire any rights in the shares. The automatic transfer will be deemed to be effective as of the close of business on the Business Day (as defined in the declaration of trust) prior to the date of the transfer. Shares held in the trust for the charitable beneficiary will be issued and outstanding shares. The proposed transferee will not benefit economically from ownership of any shares held in that trust, will have no rights to dividends or other distributions and no rights to vote or other rights attributable to the shares held in that trust. The trustee of the trust for the charitable beneficiary will have all voting rights and rights to dividends or other distributions with respect to shares held in that trust. These rights will be exercised for the exclusive benefit of the charitable beneficiary. Any dividend or other distribution paid prior to our discovery that the shares have been transferred to the trust for the charitable beneficiary will be

paid by the recipient to the trustee upon demand. Any dividend or other distribution authorized but unpaid will be paid when due to the trustee. Any dividend or other distribution paid to the trustee will be held in trust for the charitable beneficiary. Subject to Maryland law, the trustee will have the authority (i) to rescind as void any vote cast by the proposed transferee prior to our discovery that the shares have been transferred to the trust and (ii) to recast the vote in accordance with the desires of the trustee acting for the benefit of the charitable beneficiary. However, if we have already taken irreversible corporate action, then the trustee will not have the authority to rescind and recast the vote.

Within 20 days of receiving notice from us that any of our shares have been transferred to the trust for the charitable beneficiary, the trustee will sell those shares to a person designated by the trustee, whose ownership of the shares will not violate the above ownership limitations. Upon the sale, the interest of the charitable beneficiary in the shares sold will terminate, and the trustee will distribute the net proceeds of the sale to the proposed transferee and to the charitable beneficiary as follows. The proposed transferee will receive the lesser of (i) the price paid by the proposed transferee for the shares or, if the proposed transferee did not give value for the shares in connection with the event causing the shares to be held in the trust (e.g., a gift, devise or other similar transaction), the Market Price (as defined in our declaration of trust) of the shares on the day of the event causing the shares to be held in the trust and (ii) the price received by the trustee from the sale or other disposition of the shares. Any net sale proceeds in excess of the amount payable to the proposed transferee will be paid immediately to the charitable beneficiary. lf, prior to our discovery that shares have been transferred to the trust, the shares are sold by the proposed transferee, then (i) the shares shall be deemed to have been sold on behalf of the trust and (ii) to the extent that the proposed transferee received an amount for the shares that exceeds the amount he was entitled to receive, the excess shall be paid to the trustee upon demand.

In addition, shares held in the trust for the charitable beneficiary will be deemed to have been offered for sale to us, or our designee, at a price per share equal to the lesser of (i) the price per share in the transaction that resulted in the transfer to the trust (or, in the case of a devise or gift, the Market Price at the time of the devise or gift) and (ii) the Market Price on the date we, or our designee, accept the offer. We will have the right to accept the offer until the trustee has sold the shares. Upon a sale to us, the interest of the charitable beneficiary in the shares sold will terminate, and the trustee will distribute the net proceeds of the sale to the proposed transferee.

All certificates evidencing our shares will bear a legend referring to the restrictions described above.

Every owner of more than 5% (or such lower percentage as required by the Code or the regulations promulgated thereunder) of our outstanding shares, within 30 days after the end of each taxable year, is required to give us written notice, stating his, her or its name and address, the number of shares of each class and series of our shares which he, she or it beneficially owns and a description of the manner in which the shares are held. Each such owner shall provide us with such additional information as we may request in order to determine the effect, if any, of his, her or its beneficial ownership on our status as a REIT and to ensure compliance with the ownership limits. In addition, each shareholder shall upon demand be required to provide us with such information as we may request in good faith in order to determine our status as a REIT and to comply with the requirements of any taxing authority or governmental authority or to determine such compliance.

Certain Provisions of Maryland Law and of Our Declaration of Trust and Bylaws

The following is a summary of certain provisions of Maryland law and of our declaration of trust and bylaws and does not purport to be complete and is subject to and qualified in its entirety by reference to Maryland law and our declaration of trust and bylaws, copies of which are exhibits to the registration statement of which this prospectus is a part.

General. Our declaration of trust provides a perpetual existence and permits us to be terminated upon the affirmative vote of the holders of a majority of the outstanding shares entitled to vote and the approval of a majority of the entire board of trustees. Our bylaws require us to conduct annual meetings of our shareholders for the purpose of electing trustees, each of whom will serve for a three-year term, and to transact any other business as may properly come before the shareholders.

Our Board of Trustees. Our declaration of trust provides that the number of our trustees may be determined pursuant to our bylaws, and our bylaws provide that such number may be established, increased or decreased by the board of trustees but may not be fewer than one or more than fifteen. Our board of trustees is currently divided into three classes, with each trustee holding office for three years and until his or her successor is duly elected and qualifies. As described in our Definitive Proxy Statement on Schedule 14A, filed with the SEC on April 4, 2019 (the “2019 Proxy Statement”), on December 18, 2018, the board unanimously deemed it advisable and in the best interests of the Company and our shareholders to amend our declaration of trust to declassify the board on the terms described in the 2019 Proxy Statement (the “Proposed Amendment”), to submit a proposal to our shareholders at our 2019 annual meeting of shareholders to approve the Proposed Amendment and to recommend that shareholders vote in favor of such proposal. As a result, our board of trustees is currently classified into three classes, with each trustee elected for a three-year term. Commencing at our 2020 annual meeting of shareholders, members of our board of trustees will be elected to serve annual terms such that, at and after our 2022 annual meeting of shareholders, our board of trustees will no longer be classified.

Any vacancy may be filled only by the affirmative vote of a majority of the remaining trustees in office, even if the remaining trustees do not constitute a quorum, and any trustee elected to fill a vacancy will serve for the remainder of the full term of the trusteeship in which the vacancy occurred.

The board of trustees is responsible for the management of our business and affairs. We currently have a total of seven members on our board of trustees. Of our seven current trustees, six are considered independent trustees. Each trustee will serve until the annual meeting of shareholders at which his or her three-year term ends and until his or her successor has been duly elected and qualifies. Although the number of trustees may be increased or decreased, a decrease will not have the effect of shortening the term of any incumbent trustee. Any trustee may resign at any time and may be removed for cause by the shareholders upon the affirmative vote of not less than two-thirds of the shares then outstanding and entitled to vote generally in the election of trustees.

Our trustees must perform their duties in good faith and in a manner reasonably believed to be in our best interests. Further, trustees must act with such care as an ordinarily prudent person in a like position would use under similar circumstances, including exercising reasonable inquiry, when taking actions. Our declaration of trust provides that a trustee

may be removed only for cause upon the affirmative vote of not less than two-thirds of the shares then outstanding and entitled to vote generally in the election of trustees. This provision, when coupled with the exclusive power of our board of trustees to fill vacancies on the board of trustees, precludes shareholders from (i) removing incumbent trustees except for cause upon a substantial affirmative vote and (ii) filling the vacancies created by such removal with their own nominees.

Business Combinations. Under Maryland law, “business combinations” between a Maryland REIT and an interested shareholder or an affiliate of an interested shareholder are prohibited for five years after the most recent date on which the interested shareholder becomes an interested shareholder. These business combinations include a merger, consolidation, share exchange or, in circumstances specified in the statute, certain transfers of assets, certain share issuances and transfers, liquidation plans and reclassifications involving interested shareholders and their affiliates. An interested shareholder is defined as:

•any person who beneficially owns 10% or more of the voting power of the trust’s outstanding voting shares; or

•an affiliate or associate of the trust who, at any time within the two-year period prior to the date in question, was the beneficial owner of ten percent or more of the voting power of the then-outstanding shares of the trust.

A person is not an interested shareholder under the statute if the board of trustees of the trust approved in advance the transaction by which the person otherwise would have become an interested shareholder. However, in approving a transaction, the board of trustees may provide that its approval is subject to compliance, at or after the time of approval, with any terms and conditions determined by the board of trustees.

After the five-year prohibition, any business combination between a Maryland REIT and an interested shareholder generally must be recommended by the board of trustees of the trust and approved by the affirmative vote of at least:

•80% of the votes entitled to be cast by holders of the then-outstanding voting shares of the trust; and

•two-thirds of the votes entitled to be cast by holders of voting shares of the trust other than shares held by the interested shareholder with whom or with whose affiliate the business combination is to be effected or shares held by an affiliate or associate of the interested shareholder.

These super-majority vote requirements do not apply if the trust’s common shareholders receive a minimum price, as defined under Maryland law, for their shares in the form of cash or other consideration in the same form as previously paid by the interested shareholder for its shares.

The statute permits various exemptions from its provisions, including business combinations that are exempted by the board of trustees of the trust before the time that the interested shareholder becomes an interested shareholder. Pursuant to the statute, our board of trustees has exempted any business combination involving the Company and any person. Consequently, the five-year prohibition and the super-majority vote requirements will not apply to business combinations between the Company and any person.

Control Share Acquisitions. Maryland law provides that “control shares” of a Maryland REIT acquired in a “control share acquisition” have no voting rights except to the extent approved by a vote of two-thirds of the votes entitled to be cast on

the matter. Shares owned by the acquiror, by officers or by employees who are trustees of the trust are excluded from shares entitled to vote on the matter. “Control shares” are voting shares which, if aggregated with all other shares owned by the acquiror or in respect of which the acquiror is able to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquiror to exercise voting power in electing trustees within one of the following ranges of voting power:

•one-tenth or more but less than one-third;

•one-third or more but less than a majority; or

•a majority or more of all voting power.

Control shares do not include shares the acquiring person is then entitled to vote as a result of having previously obtained shareholder approval. A “control share acquisition” means the acquisition of issued and outstanding control shares, subject to certain exceptions.

A person who has made or proposes to make a control share acquisition may compel the board of trustees of the trust to call a special meeting of shareholders to be held within 50 days of demand to consider the voting rights of the shares. The right to compel the calling of a special meeting is subject to the satisfaction of certain conditions, including an undertaking to pay the expenses of the meeting. If no request for a meeting is made, the trust may itself present the question at any shareholders’ meeting.

If voting rights are not approved at the meeting or if the acquiring person does not deliver an acquiring person statement as required by the statute, then the trust may redeem for fair value any or all of the control shares, except those for which voting rights have previously been approved. The right of the trust to redeem control shares is subject to certain conditions and limitations. Fair value is determined, without regard to the absence of voting rights for the control shares, as of the date of the last control share acquisition by the acquiror or of any meeting of shareholders at which the voting rights of the shares are considered and not approved. If voting rights for control shares are approved at a shareholders meeting and the acquiror becomes entitled to vote a majority of the shares entitled to vote, all other shareholders may exercise appraisal rights. The fair value of the shares as determined for purposes of appraisal rights may not be less than the highest price per share paid by the acquiror in the control share acquisition.

The control share acquisition statute does not apply (i) to shares acquired in a merger, consolidation or share exchange if the trust is a party to the transaction or (ii) to acquisitions approved or exempted by the declaration of trust or bylaws of the trust.

Subtitle 8. Subtitle 8 of Title 3 of the Maryland General Corporation Law permits a Maryland REIT with a class of equity securities registered under the Exchange Act and at least three independent trustees to elect to be subject, by provision in its declaration of trust or bylaws or a resolution of its board of trustees and notwithstanding any contrary provision in the declaration of trust or bylaws, to any or all of five provisions:

•a classified board;

•two-thirds vote requirement for removing a trustee;

•a requirement that the number of trustees be fixed only by vote of the trustees;

•a requirement that a vacancy on the board be filled only by the remaining trustees and for the remainder of the full term of the class in which the vacancy occurred until a successor is elected and qualifies; and

•a majority requirement for the calling of a special meeting of shareholders.

Our bylaws already provide that, except as may be provided by our board of trustees in setting the terms of any class or series of preferred shares, any vacancy on the board of trustees may be filled only by a majority of the remaining trustees, even if the remaining trustees do not constitute a quorum, and any trustee elected to fill a vacancy will serve for the remainder of the full term of the trusteeship in which the vacancy occurred and until a successor is elected and qualifies. Pursuant to Subtitle 8, we have elected to be subject to the remaining provisions described above.

Amendments to Our Declaration of Trust and Bylaws. Our declaration of trust may be amended by a majority of the trustees, without any action by the shareholders (i) to qualify as a REIT under the Code or under the Maryland REIT Law, (ii) in any respect in which the charter of a corporation may be amended under the Maryland General Corporation Law, and (iii) as otherwise provided in our declaration of trust. All other amendments must be declared advisable by our board of trustees and approved by the affirmative vote of holders of a majority of all shares entitled to vote on the matter, except that any amendment to the provisions of our declaration of trust addressing the removal of trustees and certain amendments to our declaration of trust must be approved by the affirmative vote of holders of two-thirds of all shares entitled to vote on the matter. Our board of trustees has the exclusive power to adopt, amend and repeal any provision of our bylaws or to make new bylaws.

Meetings and Special Voting Requirements. An annual meeting of our shareholders will be held each year. Special meetings of shareholders may be called by the chairman of our board of trustees, a majority of our trustees, our chief executive officer or our president and must be called by or at the direction of our chief executive officer upon the written request of shareholders entitled to cast at least a majority of the votes entitled to be cast on any matter that may properly be considered at a meeting of shareholders. Upon receipt of such written request and other required information, our chief executive officer will inform the requesting shareholders of the estimated cost of preparing and mailing a notice, payment for which must be received prior to the mailing of any notice. Our board of trustees must designate a date for the special meeting within ten days of receiving the request, or if it does not, the date will be the 90th day after the record date, and the record date, unless otherwise set by our board of trustees within 30 days of receiving the request, will be the 30th day after the date of delivery of the request. The presence, either in person or by proxy, of shareholders entitled to cast a majority of all votes entitled to be cast will constitute a quorum at any meeting of shareholders. Generally, the affirmative vote of a majority of the votes cast at a meeting at which a quorum is present is sufficient to take shareholder action, except that the approval of shareholders entitled to cast at least two-thirds of the votes entitled to be cast is required remove a trustee or to amend the declaration of trust provisions addressing the removal of trustees and the vote required for certain amendments to our declaration of trust, and the affirmative vote of shareholders entitled to cast at least a majority of the votes entitled to be cast is required for:

•any other amendment of our declaration of trust, except that our board of trustees may amend our declaration of trust without shareholder approval to increase or decrease the aggregate number of our shares or the number of our shares of any class or series that we have the authority to issue, to qualify as a REIT under the Code or the Maryland REIT Law or in any respect in which the charter of a Maryland corporation may be amended without shareholder approval;

•except as permitted by law, any merger, consolidation or sale or other disposition of all or substantially all of our assets (which also requires the approval of our board of trustees); and

•our termination (which also must be approved by action of our board of trustees).

Advance Notice of Trustee Nominations and New Business. Our bylaws provide that with respect to an annual meeting of shareholders, nominations of individuals for election to our board of trustees and the proposal of business to be considered by shareholders may be made only (i) pursuant to our notice of the meeting, (ii) by or at the direction of our board of trustees, or (iii) by a shareholder who is a shareholder of record both at the time of giving the advance notice required by our bylaws and at the time of the meeting, who is entitled to vote at the meeting in the election of each individual so nominated or on any such other business and who has complied with the advance notice procedures of the bylaws. With respect to special meetings of shareholders, only the business specified in our notice of the meeting may be brought before the meeting, unless otherwise provided by law. Nominations of individuals for election to the board of trustees at a special meeting may be made only (i) by or at the direction of the board of trustees or (ii) provided that the meeting has been called in accordance with our bylaws for the purpose of electing trustees, by a shareholder who is a shareholder of record both at the time of giving the advance notice required by our bylaws and at the time of the meeting, who is entitled to vote at the meeting in the election of each individual so nominated and who has complied with the advance notice provisions of the bylaws.

Limited Liability and Indemnification of Trustees, Officers, Employees and Other Agents. Maryland law also permits us to include in our declaration of trust a provision limiting the liability of our trustees and officers to us and our shareholders for money damages, except for liability resulting from (i) actual receipt of an improper benefit or profit in money, property or services or (ii) active and deliberate dishonesty established by a final judgment and that is material to the cause of action. Our declaration of trust contains a provision that eliminates trustees’ and officers’ liability to the maximum extent permitted by Maryland law.

Maryland law permits a Maryland REIT to indemnify and advance expenses to its trustees, officers, employees and agents to the same extent as permitted for directors and officers of Maryland corporations. Maryland law permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made or threatened to be made a party by reason of their service in those or other capacities unless it is established that:

•the act or omission of the trustee or officer was material to the matter giving rise to the proceeding and (i) was committed in bad faith or (ii) was the result of active and deliberate dishonesty;

•the trustee or officer actually received an improper personal benefit in money, property or services; or

•in the case of any criminal proceeding, the trustee or officer had reasonable cause to believe that the act or omission was unlawful.

However, a Maryland REIT may not indemnify for an adverse judgment in a suit by or in the right of the corporation or for a judgment of liability on the basis that personal benefit was improperly received, unless in either case a court orders indemnification and then only for expenses. In addition, Maryland law permits a Maryland REIT to advance reasonable expenses to a director or officer upon the corporation’s receipt of:

•a written affirmation by the trustee or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the corporation; and

•a written undertaking by the trustee or officer or on the director’s or officer’s behalf to repay the amount paid or reimbursed by the corporation if it is ultimately determined that the standard of conduct was not met.

Our declaration of trust authorizes our Company, to the maximum extent permitted by Maryland law, to obligate itself to indemnify any present or former trustee or officer or any individual who, while a trustee or officer and at our request, serves or has served another REIT, corporation, partnership, joint venture, trust, employee benefit plan or other enterprise as a trustee, officer, partner, employee or agent, against any claim or liability arising from that status and to pay or reimburse their reasonable expenses in advance of final disposition of a proceeding. Our bylaws obligate us to provide such indemnification and advance of expenses. Our declaration of trust and bylaws also permit us to indemnify and advance expenses to any person who served our predecessor in any of the capacities described above and any employee or agent of us or our predecessor.

Our Operating Partnership must indemnify us and our trustees and officers from any liability, loss, cost or damage incurred by us and our trustees and officers by reason of anything done or refrained from in connection with our Operating Partnership, except for any liability, loss, cost or damage incurred as a result of fraud, willful misconduct or gross negligence.

In addition, the partnership agreement expressly limits our liability by providing that we shall not be liable or accountable to our Operating Partnership for anything in the absence of fraud, willful misconduct or gross negligence and breaches of the partnership agreement, and we shall not be liable to our Operating Partnership for money damages except (i) for active and deliberate dishonesty established by a final judgment, order or decree of a court of competent jurisdiction or (ii) if the indemnified party received an improper personal benefit in money, property or services.

CERTIFICATION OF CHIEF EXECUTIVE OFFICER PURSUANT TO

AS ADOPTED PURSUANT TO

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

EARNINGS PER SHARE

Basic earnings per share for our common shareholders is calculated by dividing income from continuing operations excluding amounts attributable to unvested restricted shares and the net income attributable to non-controlling interests by our weighted-average common shares outstanding during the period.  Diluted earnings per share is computed by dividing the net income attributable to common shareholders excluding amounts attributable to unvested restricted shares and the net income attributable to non-controlling interests by the weighted-average number of common shares including any dilutive unvested restricted shares.

Certain of our performance-based restricted common shares are considered participating securities, which require the use of the two-class method for the computation of basic and diluted earnings per share.   During the years ended December 31, 2019, 2018 and 2017, 924,314, 1,011,268 and 1,088,292 OP units, respectively, were excluded from the calculation of diluted earnings per share because their effect would be anti-dilutive.

For the years ended December 31, 2019, 2018 and 2017, distributions of $41,000, $317,000 and $472,000, respectively, were made to the holders of certain restricted common shares, $0, $16,000, and $16,000 of which were charged against earnings, annually for the years ended December 31, 2019, 2018, and 2017, respectively.  See Note 15 for information related to restricted common shares under the 2008 Plan.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Incentive Share Plan

INCENTIVE SHARE PLAN

On July 29, 2008, our shareholders approved the 2008 Plan. On December 22, 2010, our board of trustees amended the 2008 Plan to allow for awards in or related to Class B common shares pursuant to the 2008 Plan. On June 27, 2012, our Class B common shares were redesignated as “common shares.” The 2008 Plan, as amended, provides that awards may be made with respect to common shares of Whitestone or OP units, which may be redeemed for cash or, at our option, common shares of Whitestone. The maximum aggregate number of common shares that may be issued under the 2008 Plan is increased upon each issuance of common shares by Whitestone so that at any time the maximum number of common shares that may be issued under the 2008 Plan shall equal 12.5% of the aggregate number of common shares of Whitestone and OP units issued and outstanding (other than shares and/or units issued to or held by Whitestone).

The Compensation Committee of our board of trustees administers the 2008 Plan, except with respect to awards to non-employee trustees, for which the 2008 Plan is administered by our board of trustees.  The Compensation Committee is authorized to grant share options, including both incentive share options and non-qualified share options, as well as share appreciation rights, either with or without a related option. The Compensation Committee is also authorized to grant restricted common shares, restricted common share units, performance awards and other share-based awards. 

On April 2, 2014, the Compensation Committee approved the modification of the vesting provisions with respect to awards of an aggregate of 633,704 restricted common shares and restricted common share units for certain of our employees. The modified time-based shares vested annually in three equal installments. The modified performance-based restricted common shares and restricted common share units were modified to include performance-based vesting based on achievement of certain absolute financial goals, as well as one to two years of time-based vesting post achievement of financial goals. Continued employment is required through the applicable vesting date. Additionally, 2,049,116 restricted performance-based common share units were granted with the same vesting conditions as the modified performance-based grants described above. The performance targets were not met prior to December 31, 2018, any unvested performance-based restricted common shares and restricted common share units were forfeited due to the performance targets not being met.

The Compensation Committee approved the grant of an aggregate of 320,000 and 143,000 time-based restricted common share units on June 30, 2016 and 2015, respectively, to James C. Mastandrea and David K. Holeman.

On September 6, 2017, the Compensation Committee approved the grant of an aggregate of 267,783 performance-based restricted common share units under the 2008 Plan with market-based vesting conditions (the “TSR Units”) to certain of our employees. Vesting is contingent upon achieving Total Shareholder Return relative to the peer group defined in the TSR Unit award agreements over a three-year performance period. At the end of the performance period, the number of common shares awarded for each vested TSR Unit will be 200% based on the Company’s ranking in the peer group (the “TSR Peer Group Ranking”). Continued employment is required through the vesting date. The grant date fair value for each TSR Unit of $12.37 was determined using the Monte Carlo simulation method and is being recognized as share-based compensation expense ratably from the September 30, 2017 grant date to the end of the performance period, December 31, 2019. The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the award grant and calculates the fair value of the award. Expected volatilities utilized in the model were estimated using a historical period consistent with the performance period of approximately three years. The risk-free interest rate was based on the United States Treasury rate for a term commensurate with the expected life of the grant. On January 1, 2020, the remaining unvested 247,978 TSR units that were granted on September 6, 2017 vested at 200% achievement into 495,956 common shares.

On September 6, 2017, the Compensation Committee approved the grant of an aggregate of 965,000 performance-based restricted common share units under the 2008 Plan which only vest immediately prior to the consummation of a Change in Control (as defined in the 2008 Plan) that occurs on or before September 30, 2024 (the “CIC Units”) to certain of our employees. Continued employment is required through the vesting date. If a Change in Control does not occur on or before September 30, 2024, the CIC Units shall be immediately forfeited. The Company considers a Change in Control on or before September 30, 2024 to be improbable, and no expense has been recognized for the CIC Units. If a Change in Control occurs, any outstanding CIC Units would be expensed immediately on the date of the Change in Control using the grant date fair value. The grant date fair value for each CIC Unit of $13.05 was determined based on the Company’s closing share price on the grant date.

At the Company’s annual meeting of shareholders on May 11, 2017, its shareholders voted to approve the 2018 Long-Term Equity Incentive Ownership Plan (the “2018 Plan”). The 2018 Plan provides for the issuance of up to 3,433,831 common shares and OP units pursuant to awards under the 2018 Plan. The 2018 Plan became effective on July 30, 2018, which was the day after the 2008 Plan expired.

The Compensation Committee administers the 2018 Plan, except with respect to awards to non-employee trustees, for which the 2018 Plan is administered by the Board of Trustees.  The Compensation Committee is authorized to grant share options, including both incentive share options and non-qualified share options, as well as share appreciation rights, either with or without a related option. The Compensation Committee is also authorized to grant restricted common shares, restricted common share units, performance awards and other share-based awards

    On December 1, 2018, the Compensation Committee approved the grant of an aggregate of 229,684 TSR Units under the 2018 Plan to certain of our employees. Vesting is contingent upon achieving Total Shareholder Return relative to the peer group defined in the TSR Unit award agreements over a three-year performance period. At the end of the performance period, the number of common shares awarded for each vested TSR Unit will vary from 0% to 200% depending on the Company’s TSR Peer Group Ranking. Continued employment is required through the vesting date. The grant date fair value for each TSR Unit of $14.89 was determined using the Monte Carlo simulation method and is being recognized as share-based compensation expense ratably from the December 1, 2018 grant date to the end of the performance period, December 31, 2020. The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the award grant and calculates the fair value of the award. Expected volatilities utilized in the model were estimated using a historical period consistent with the performance period of approximately three years. The risk-free interest rate was based on the United States Treasury rate for a term commensurate with the expected life of the grant.

On June 30, 2019, the Compensation Committee approved the grant of an aggregate of 405,417 TSR Units and 317,184 time-based restricted common share units under the 2018 Plan to certain of our employees. On September 30, 2019, the Compensation Committee approved the grant of 17,069 time-based restricted common share units under the 2018 Plan to certain of our employees. Vesting of the TSR Units is contingent upon achieving Total Shareholder Return relative to the peer group defined in the TSR Unit award agreements over a three-year performance period. At the end of the performance period, the number of common shares awarded for each vested TSR Unit will vary from 0% to 200% depending on the Company’s TSR Peer Group Ranking. Continued employment is required through the vesting date. The grant date fair value for each TSR Unit of $8.22 was determined using the Monte Carlo simulation method and is being recognized as share-based compensation expense ratably from the June 30, 2019 grant date to the end of the performance period, December 31, 2021. The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the award grant and calculates the fair value of the award. Expected volatilities utilized in the model were estimated using a historical period consistent with the performance period of approximately three years. The risk-free interest rate was based on the United States Treasury rate for a term commensurate with the expected life of the grant. The time-based restricted common share units have a grant date fair value of $10.63 and $11.69 and vest annually in three equal installments for the June 30, 2019 and September 30, 2019 grants, respectively.

A summary of the share-based incentive plan activity as of and for the year ended December 31, 2019 is as follows:

	Shares		Weighted-Average Grant Date Fair Value (1)
Non-vested at January 1, 2019	1,923,382		$	12.41
Granted	762,630		9.46
Vested	(284,964	)	11.76
Forfeited	(61,116	)	12.62
Non-vested at December 31, 2019	2,339,932		$	11.52
Available for grant at December 31, 2019	1,792,528

⁽¹⁾  The fair value of the shares granted were determined based on observable market transactions occurring near the date of the grants.

A summary of our nonvested and vested shares activity for the years ended December 31, 2019, 2018 and 2017 is presented below:

	Shares Granted			Shares Vested
Year Ended	Non-Vested Shares Issued	Weighted-Average Grant-Date Fair Value		Vested Shares		Total Vest-Date Fair Value
						(in thousands)
Year Ended December 31, 2019	762,630	$	9.46	(284,964	)	$	3,352
Year Ended December 31, 2018	653,472	$	11.07	(560,126	)	$	7,978
Year Ended December 31, 2017	1,354,534	$	12.92	(881,710	)	$	12,829

Total compensation recognized in earnings for share-based payments for the years ended December 31, 2019, 2018 and 2017 was $6.5 million, $6.8 million and $10.4 million, respectively.

Based on our current financial projections, we expect 100% of the unvested awards, exclusive of 895,000 CIC Units, to vest over the next 33 months. As of December 31, 2019, there was approximately $4.2 million in unrecognized compensation cost related to outstanding non-vested TSR Units, which are expected to vest over a period of 24 months and approximately $4.2 million in unrecognized compensation cost related to outstanding non-vested time-based shares, which are expected to be recognized over a period of approximately 33 months beginning on January 1, 2020.

We expect to record approximately $8.4 million in share-based compensation subsequent to the year ended December 31, 2019. The unrecognized share-based compensation cost is expected to vest over a weighted average period of 23 months. The dilutive impact of the performance-based shares will be included in the denominator of the earnings per share calculation beginning in the period that the performance conditions are expected to be met. The dilutive impact of the TSR Units is based on the Company’s TSR Peer Group Ranking as of the reporting date and weighted according to the number of days outstanding in the period. As of December 31, 2019, the TSR Peer Group Ranking called for 200%, 100%, and 50% attainment of the TSR Units granted in 2017, 2018, and 2019, respectively. The dilutive impact of the CIC Units is based on the probability of a Change in Control. Because the Company considers a Change in Control on or before September 30, 2024 to be improbable, no CIC Units are included in the Company’s dilutive shares.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2019

Accounting Policies [Abstract]

Basis of Consolidation

Basis of Consolidation.  We are the sole general partner of the Operating Partnership and possess full legal control and authority over the operations of the Operating Partnership.  As of December 31, 2019, 2018 and 2017, we owned a majority of the partnership interests in the Operating Partnership. Consequently, the accompanying consolidated financial statements include the accounts of the Operating Partnership.

Noncontrolling interest in the accompanying consolidated financial statements represents the share of equity and earnings of the Operating Partnership allocable to holders of partnership interests other than us.  Net income or loss is allocated to noncontrolling interests based on the weighted-average percentage ownership of the Operating Partnership during the year.  Issuance of additional common shares of beneficial interest in Whitestone (the “common shares”) and units of limited partnership interest in the Operating Partnership that are convertible into cash or, at our option, common shares on a one-for-one basis (the “OP units”) changes the percentage of ownership interests of both the noncontrolling interests and Whitestone.

Profit-sharing Method

Profit-sharing Method. In accordance with the Financial Accounting Standards Board’s (“FASB”) guidance applicable to sales of real estate or interests therein, specifically FASB Accounting Standards Codification (“ASC”) 360-20, “Real Estate Sales,” Topic 606, “Revenue from Contracts with Customers” and ASC 610, “Other Income–Gains and Losses from the Derecognition of Nonfinancial Assets,” we did not recognize the sale of assets to Pillarstone OP in the Contribution (as defined in Note 5) and accounted for the transaction under the profit-sharing method for the year ended December 31, 2017. We recognized Pillarstone OP’s real estate assets and notes payables in our consolidated balance sheets. Additionally, the profits and losses of Pillarstone OP not attributable to the Company are reported as profit sharing expense. As a result of the adoption of Topic 606 and ASC 610, the Company derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and recognized the Company’s investment in Pillarstone OP under the equity method.

Equity Method

Noncontrolling Interests.  Noncontrolling interests are the portion of equity in a subsidiary not attributable to a parent.  The ownership interests not held by the parent are considered noncontrolling interests.  Accordingly, we have reported noncontrolling interests in equity on the consolidated balance sheets but separate from Whitestone’s equity.  On the consolidated statements of operations and comprehensive income, subsidiaries are reported at the consolidated amount, including both the amount attributable to Whitestone and noncontrolling interests.  Consolidated statements of changes in equity are included for both quarterly and annual financial statements, including beginning balances, activity for the period and ending balances for shareholders’ equity, noncontrolling interests and total equity.

Equity Method. For the years prior to December 31, 2017, Pillarstone OP was accounted for under the profit-sharing method. We adopted Topic 606 and ASC 610 as of January 1, 2018, resulting in the derecognition of the underlying assets and liabilities associated with the Contribution (defined below) as of January 1, 2018 and the recognition of the Company’s investment in Pillarstone OP under the equity method. See Note 5 for additional disclosure on Pillarstone OP.

Basis of Accounting

Basis of Accounting.  Our financial records are maintained on the accrual basis of accounting whereby revenues are recognized when earned and expenses are recorded when incurred.

Use of Estimates

Use of Estimates.   The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Significant estimates that we use include the estimated fair values of properties acquired, the estimated useful lives for depreciable and amortizable assets and costs, the estimated allowance for doubtful accounts, the estimated fair value of interest rate swaps and the estimates supporting our impairment analysis for the carrying values of our real estate assets.  Actual results could differ from those estimates.

Reclassifications

Reclassifications.  We have reclassified certain prior year amounts in the accompanying consolidated financial statements in order to be consistent with the current fiscal year presentation. Other than the effects noted below, these reclassifications had no effect on net income, total assets, total liabilities or equity.

Restricted Cash

Restricted Cash. We classify all cash pledged as collateral to secure certain obligations and all cash whose use is limited as restricted cash. During 2015, pursuant to the terms of our $15.1 million4.99% Note, due January 6, 2024, which is collateralized by our Anthem Marketplace property, we were required by the lenders thereunder to establish a cash management account controlled by the lenders to collect all amounts generated by our Anthem Marketplace property in order to collateralize such promissory note.

Share-Based Compensation

Share-Based Compensation.   From time to time, we award nonvested restricted common share awards or restricted common share unit awards, which may be converted into common shares, to executive officers and employees under our 2018 Long-Term Equity Incentive Ownership Plan (the “2018 Plan”).  Awarded shares and units vest when certain performance conditions are met.  We recognize compensation expense when achievement of the performance conditions is probable based on management’s most recent estimates using the fair value of the shares as of the grant date.

Revenue Recognition

Revenue Recognition.  All leases on our properties are classified as operating leases, and the related rental income is recognized on a straight-line basis over the terms of the related leases.  Differences between rental income earned and amounts due per the respective lease agreements are capitalized or charged, as applicable, to accrued rents and accounts receivable. Percentage rents are recognized as rental income when the thresholds upon which they are based have been met.  Recoveries from tenants for taxes, insurance, and other operating expenses are recognized as revenues in the period the corresponding costs are incurred. We combine lease and nonlease components in lease contracts, which includes combining base rent, recoveries, and percentage rents into a single line item, Rental, within the consolidated statements of operations and comprehensive income. Additionally, we have tenants who pay real estate taxes directly to the taxing authority. We exclude these costs paid directly by the tenant to third parties on our behalf from revenue recognized and the associated property operating expense.

Other property income primarily includes amounts recorded in connection with management fees and lease termination fees. Pillarstone OP pays us management fees for property management, leasing and day-to-day advisory and administrative services. Their obligations are satisfied over time. Pillarstone OP is billed monthly and typically pays quarterly. Revenues are governed by the Management Agreements (as defined in Note 5). Refer to Note 5 to our accompanying consolidated financial statements for additional information regarding the Management Agreements with Pillarstone OP. Additionally, we recognize lease termination fees in the year that the lease is terminated and collection of the fee is probable. Amounts recorded within other property income are accounted for at the point in time when control of the goods or services transfers to the customer and our performance obligation is satisfied.

Cash and Cash Equivalents

Cash and Cash Equivalents.  We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.  Cash and cash equivalents as of December 31, 2019 and 2018 consisted of demand deposits at commercial banks and brokerage accounts. We may have net book credit balances in our primary disbursement accounts at the end of a reporting period. We classify such credit balances as accounts payable in our consolidated balance sheets as checks presented for payment to these accounts are not payable by our banks under overdraft arrangements, and, therefore, do not represent short-term borrowings.

Marketable Securities

Marketable Securities. We classify our existing marketable equity securities as available-for-sale in accordance with the Financial Accounting Standards Board’s (“FASB”) Investments-Debt and Equity Securities guidance. These securities are carried at fair value with unrealized gains and losses reported in equity as a component of accumulated other comprehensive income or loss. The fair value of the marketable securities is determined using Level 1 inputs under FASB Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures.” Level 1 inputs represent quoted prices available in an active market for identical investments as of the reporting date. Gains and losses on securities sold are based on the specific identification method, and are reported as a component of interest, dividend and other investment income.

Development Properties

Development Properties.  Land, buildings and improvements are recorded at cost. Expenditures related to the development of real estate are carried at cost which includes capitalized carrying charges and development costs. Carrying charges (interest, real estate taxes, loan fees, and direct and indirect development costs related to buildings under construction) are capitalized as part of construction in progress. The capitalization of such costs ceases when the property, or any completed portion, becomes available for occupancy.

Acquired Properties and Acquired Lease Intangibles

Acquired Properties and Acquired Lease Intangibles.  We allocate the purchase price of the acquired properties to land, building and improvements, identifiable intangible assets and to the acquired liabilities based on their respective fair values at the time of purchase. Identifiable intangibles include amounts allocated to acquired out-of-market leases, the value of in-place leases and customer relationship value, if any. We determine fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends and specific market and economic conditions that may affect the property. Factors considered by management in our analysis of determining the as-if-vacant property value include an estimate of carrying costs during the expected lease-up periods considering market conditions, and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and estimates of lost rentals at market rates during the expected lease-up periods, tenant demand and other economic conditions. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related expenses. Intangibles related to out-of-market leases and in-place lease value are recorded as acquired lease intangibles and are amortized as an adjustment to rental revenue or amortization expense, as appropriate, over the remaining terms of the underlying leases. Premiums or discounts on acquired out-of-market debt are amortized to interest expense over the remaining term of such debt.

Depreciation

Depreciation.  Depreciation is computed using the straight-line method over the estimated useful lives of 5 to 39 years for improvements and buildings, respectively.  Tenant improvements are depreciated using the straight-line method over the life of the improvement or remaining term of the lease, whichever is shorter.

Impairment

Impairment.  We review our properties for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations.  We determine whether an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of the property, with the carrying cost of the property.  If impairment is indicated, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value.  Management has determined that there has been no impairment in the carrying value of our real estate assets as of December 31, 2019.

Accrued Rents and Accounts Receivable

Accrued Rents and Accounts Receivable.  Included in accrued rents and accounts receivable are base rents, tenant reimbursements and receivables attributable to recording rents on a straight-line basis. We review the collectability of charges under our tenant operating leases on a regular basis, taking into consideration changes in factors such as the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area where the property is located. With the adoption of ASC No. 842, Leases (“Topic 842”), as of January 1, 2019 we recognize an adjustment to rental revenue if we deem it probable that the receivable will not be collected. Prior to the adoption of Topic 842, we recognized an allowance for doubtful accounts and bad debt expense of the specific rents receivable. Our review of collectability under our operating leases includes any accrued rental revenues related to the straight-line method of reporting rental revenue.

Unamortized Lease Commissions and Loan Costs

Unamortized Lease Commissions and Loan Costs.  Leasing commissions are amortized using the straight-line method over the terms of the related lease agreements.  Loan costs are amortized on the straight-line method over the terms of the loans, which approximates the interest method.  Costs allocated to in-place leases whose terms differ from market terms related to acquired properties are amortized over the remaining life of the respective leases.

Prepaids and Other Assets, Policy

Prepaids and Other Assets.  Prepaids and other assets include escrows established pursuant to certain mortgage financing arrangements for real estate taxes and insurance and acquisition deposits which include earnest money deposits on future acquisitions.

Federal Income and State Taxes

Federal Income Taxes.  We elected to be taxed as a REIT under the Code beginning with our taxable year ended December 31, 1999.  As a REIT, we generally are not subject to federal income tax on income that we distribute to our shareholders.  If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax on our taxable income at regular corporate rates.  We believe that we are organized and operate in such a manner as to qualify to be taxed as a REIT, and we intend to operate so as to remain qualified as a REIT for federal income tax purposes.

State Taxes.  We are subject to the Texas Margin Tax, which is computed by applying the applicable tax rate (1% for us) to the profit margin, which, generally, will be determined for us as total revenue less a 30% standard deduction.  Although the Texas Margin Tax is not considered an income tax, FASB ASC 740, “Income Taxes” (“ASC 740”)applies to the Texas Margin Tax.

Fair Value of Financial Instruments

Fair Value of Financial Instruments.  Our financial instruments consist primarily of cash, cash equivalents, accounts receivable, accounts and notes payable and investments in marketable securities.  The carrying value of cash, cash equivalents, accounts receivable and accounts payable are representative of their respective fair values due to their short-term nature.  The fair value of our long-term debt, consisting of fixed rate secured notes, variable rate secured notes and an unsecured revolving credit facility aggregate to approximately $653.7 million and $618.6 million as compared to the book value of approximately $645.9 million and $619.4 million as of December 31, 2019 and 2018, respectively. The fair value of our long-term debt is estimated on a Level 2 basis (as provided by ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”)), using a discounted cash flow analysis based on the borrowing rates currently available to us for loans with similar terms and maturities, discounting the future contractual interest and principal payments.

The fair value of our loan guarantee to Pillarstone OP is estimated on a Level 3 basis (as provided by ASC 820, “Fair Value Measurements and Disclosures”), using a probability-weighted discounted cash flow analysis based on a discount rate, discounting the loan balance. The fair value of the loan guarantee is $0.1 million and $0.3 million as compared to the book value of approximately $0.1 million and $0.3 million as of December 31, 2019 and 2018, respectively.

Disclosure about fair value of financial instruments is based on pertinent information available to management as of December 31, 2019 and 2018. Although management is not aware of any factors that would significantly affect the fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since December 31, 2019 and current estimates of fair value may differ significantly from the amounts presented herein.

Derivative Instruments and Hedging Activities

Derivative Instruments and Hedging Activities. We utilize derivative financial instruments, principally interest rate swaps, to manage our exposure to fluctuations in interest rates. We have established policies and procedures for risk assessment, and the approval, reporting and monitoring of derivative financial instruments. We recognize our interest rate swaps as cash flow hedges with the effective portion of the changes in fair value recorded in comprehensive income and subsequently reclassified into earnings in the period that the hedged transaction affects earnings. Any ineffective portion of a cash flow hedge’s change in fair value is recorded immediately into earnings. Our cash flow hedges are determined using Level 2 inputs under ASC 820. Level 2 inputs represent quoted prices in active markets for similar assets or liabilities; quoted prices in markets that are not active; and model-derived valuations whose inputs are observable. As of December 31, 2019, we consider our cash flow hedges to be highly effective.

Concentration of Risk

Concentration of Risk.  Substantially all of our revenues are obtained from office, warehouse and retail locations in the Austin, Chicago, Dallas-Fort Worth, Houston, Phoenix and San Antonio metropolitan areas. We maintain cash accounts in major U.S. financial institutions. The terms of these deposits are on demand to minimize risk. The balances of these accounts sometimes exceed the federally insured limits, although no losses have been incurred in connection with these deposits.

Recent Accounting Pronouncements

Recent Accounting Pronouncements. In May 2014, the FASB issued guidance, as amended in subsequent updates, establishing a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and superseded most of the existing revenue recognition guidance. The standard also required an entity to recognize revenue to depict the transfer of promised 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 and also required certain additional disclosures. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a modified retrospective basis beginning January 1, 2018 and have derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and have recognized the Company’s investment in Pillarstone OP under the equity method of accounting. The Company made an adjustment which decreased the Company’s accumulated deficit as of January 1, 2018 by $19.1 million. See Note 5 for further details.

In February 2016, FASB issued ASU No. 2016-2 which provided the principles for the recognition, measurement, presentation and disclosure of leases. Additional guidance and targeted improvements to Topic 842 were made through the issuance of supplementary ASUs in July 2018, December 2018 and March 2019.

Effective January 1, 2019, we adopted the new lease accounting guidance in Topic 842. As the lessee and lessor, we have elected the package of practical expedients permitted in Topic 842. Accordingly, we have accounted for our existing operating leases as operating leases under the new guidance, without reassessing (a) whether the contract contains a lease under Topic 842, (b) whether classification of the operating lease would be different in accordance with Topic 842, or (c) whether the unamortized initial direct costs before transition adjustments (as of December 31, 2018) would have met the definition of initial direct costs in Topic 842 at lease commencement. Additionally, as the lessee and lessor we will use hindsight in determining the lease term and in assessing impairment of our right-of-use assets. As a result of the adoption of the new lease accounting guidance, as the lessee, we recognized on January 1, 2019 (a) a lease liability of approximately $1.1 million, which represents the present value of the remaining lease payments of approximately $1.2 million discounted using our incremental borrowing rate of 4.5%, and (b) a right-of-use asset of approximately $1.1 million. The adoption of Topic 842 did not have a material impact to our net income and related per share amounts.

Upon adoption of Topic 842, lessees and lessors are required to apply a modified retrospective transition approach. Reporting entities are permitted to choose one of two methods to recognize and measure leases within the scope of Topic 842:

• Apply Topic 842 to each lease that existed at the beginning of the earliest comparative period presented in the financial statements as well as leases that commenced after that date. Under this method, prior comparative periods presented are adjusted. For leases that commenced prior to the beginning of the earliest comparative period presented, a cumulative-effect adjustment is recognized at that date.

• Apply the guidance to each lease that had commenced as of the beginning of the reporting period in which the entity first applies the lease standard with a cumulative-effect adjustment as of that date. Prior comparative periods would not be adjusted under this method.

We have elected an optional transition method that allows entities to initially apply Topic 842 at January 1, 2019, the date of adoption, and to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. As the lessor, we have not assessed unamortized legal costs as part of the package of practical expedients, and we will not make any adjustment to retained earnings at the date of adoption to write off unamortized legal costs. We will continue to amortize unamortized legal costs as of December 31, 2018 over the life of the respective leases. We did not have a cumulative-effect adjustment as of the adoption date. Additionally, the optional transition method does allow us to not have to apply the new standard (including disclosure requirements) to comparative periods presented. Those periods can continue to be presented in accordance with prior generally accepted accounting principles.

Topic 842 requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases and operating leases. Based on our election of the package of practical expedients, our existing commercial leases, where we are the lessor, continue to be accounted for as operating leases under the new standard. However, Topic 842 changed certain requirements regarding the classification of leases that could result in us recognizing certain long-term leases entered into or modified after January 1, 2019 as sales-type leases or finance leases, as opposed to operating leases. We will continue to monitor our leases following the adoption date to ensure that they are classified in accordance with the new lease standards.

We elected a practical expedient which allows lessors to not separate non-lease components from the lease component when the timing and pattern of transfer for the lease components and non-lease components are the same and if the lease component is classified as an operating lease. As a result, we now present all rentals and reimbursements from tenants as a single line item, Rental, within the consolidated statements of operations and comprehensive income.

We review the collectability of charges under our tenant operating leases on a regular basis, taking into consideration changes in factors such as the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area where the property is located. Each tenant is included in one of several portfolios and an allowance is calculated using the calculation methodology for the respective portfolio. With the adoption of Topic 842, we will recognize an adjustment to rental revenue if we deem it probable that the receivable will not be collected. Prior to the adoption of Topic 842, we recognized an allowance for doubtful accounts and bad debt expense of the specific rents receivable. Our review of collectability under our operating leases includes any accrued rental revenues related to the straight-line method of reporting rental revenue.

In November 2016, the FASB issued guidance requiring that the statement of cash flows explain the change during the period in the total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance effective January 1, 2018, and we have reconciled cash and cash equivalents and restricted cash and restricted cash equivalents on a retrospective basis, whereas under the previous guidance, we reported restricted cash and restricted cash equivalents under cash flows from financing activities.

In January 2017, the FASB issued guidance clarifying the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or dispositions) of assets or businesses. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a prospective basis beginning January 1, 2018 and believe the majority of our future acquisitions will qualify as asset acquisitions and the associated transaction costs will be capitalized as opposed to expensed under previous guidance. For the year ending December 31, 2019, we capitalized $0.1 million in associated transaction costs.

In February 2017, the FASB issued guidance clarifying the scope of asset derecognition guidance, adding guidance for partial sales of nonfinancial assets and clarifying recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a modified retrospective basis beginning January 1, 2018 and have derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and have recognized the Company’s investment in Pillarstone OP under the equity method of accounting. The Company made an adjustment which decreased the Company’s accumulated deficit as of January 1, 2018 by $19.1 million. See Note 5 for further details.

Summary of Significant Accounting Policies

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Consolidation.  We are the sole general partner of the Operating Partnership and possess full legal control and authority over the operations of the Operating Partnership.  As of December 31, 2019, 2018 and 2017, we owned a majority of the partnership interests in the Operating Partnership. Consequently, the accompanying consolidated financial statements include the accounts of the Operating Partnership.

Noncontrolling interest in the accompanying consolidated financial statements represents the share of equity and earnings of the Operating Partnership allocable to holders of partnership interests other than us.  Net income or loss is allocated to noncontrolling interests based on the weighted-average percentage ownership of the Operating Partnership during the year.  Issuance of additional common shares of beneficial interest in Whitestone (the “common shares”) and units of limited partnership interest in the Operating Partnership that are convertible into cash or, at our option, common shares on a one-for-one basis (the “OP units”) changes the percentage of ownership interests of both the noncontrolling interests and Whitestone.

Profit-sharing Method. In accordance with the Financial Accounting Standards Board’s (“FASB”) guidance applicable to sales of real estate or interests therein, specifically FASB Accounting Standards Codification (“ASC”) 360-20, “Real Estate Sales,” Topic 606, “Revenue from Contracts with Customers” and ASC 610, “Other Income–Gains and Losses from the Derecognition of Nonfinancial Assets,” we did not recognize the sale of assets to Pillarstone OP in the Contribution (as defined in Note 5) and accounted for the transaction under the profit-sharing method for the year ended December 31, 2017. We recognized Pillarstone OP’s real estate assets and notes payables in our consolidated balance sheets. Additionally, the profits and losses of Pillarstone OP not attributable to the Company are reported as profit sharing expense. As a result of the adoption of Topic 606 and ASC 610, the Company derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and recognized the Company’s investment in Pillarstone OP under the equity method.

Equity Method. For the years prior to December 31, 2017, Pillarstone OP was accounted for under the profit-sharing method. We adopted Topic 606 and ASC 610 as of January 1, 2018, resulting in the derecognition of the underlying assets and liabilities associated with the Contribution (defined below) as of January 1, 2018 and the recognition of the Company’s investment in Pillarstone OP under the equity method. See Note 5 for additional disclosure on Pillarstone OP.

As of December 31, 2019, we, through our investment in Pillarstone OP, owned a majority interest in eight properties that do not meet our Community Centered Property® strategy containing approximately 0.9 million square feet of GLA. We own 81.4% of the total outstanding units of Pillarstone OP. We also manage the day-to-day operations of Pillarstone OP. In this Annual Report on Form 10-K, unless otherwise indicated, we do not include the Pillarstone Properties when we refer to our properties.

Basis of Accounting.  Our financial records are maintained on the accrual basis of accounting whereby revenues are recognized when earned and expenses are recorded when incurred.

Use of Estimates.   The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Significant estimates that we use include the estimated fair values of properties acquired, the estimated useful lives for depreciable and amortizable assets and costs, the estimated allowance for doubtful accounts, the estimated fair value of interest rate swaps and the estimates supporting our impairment analysis for the carrying values of our real estate assets.  Actual results could differ from those estimates.

Reclassifications.  We have reclassified certain prior year amounts in the accompanying consolidated financial statements in order to be consistent with the current fiscal year presentation. Other than the effects noted below, these reclassifications had no effect on net income, total assets, total liabilities or equity.

Restricted Cash. We classify all cash pledged as collateral to secure certain obligations and all cash whose use is limited as restricted cash. During 2015, pursuant to the terms of our $15.1 million4.99% Note, due January 6, 2024, which is collateralized by our Anthem Marketplace property, we were required by the lenders thereunder to establish a cash management account controlled by the lenders to collect all amounts generated by our Anthem Marketplace property in order to collateralize such promissory note.

Share-Based Compensation.   From time to time, we award nonvested restricted common share awards or restricted common share unit awards, which may be converted into common shares, to executive officers and employees under our 2018 Long-Term Equity Incentive Ownership Plan (the “2018 Plan”).  Awarded shares and units vest when certain performance conditions are met.  We recognize compensation expense when achievement of the performance conditions is probable based on management’s most recent estimates using the fair value of the shares as of the grant date.  We recognized $6.5 million, $6.8 million and $10.4 million in share-based compensation expense for the years ended December 31, 2019, 2018 and 2017, respectively.  

At our annual meeting of shareholders on May 11, 2017, our shareholders voted to approve the 2018 Plan. The 2018 Plan provides for the issuance of up to 3,433,831 common shares and OP units pursuant to awards under the 2018 Plan. The 2018 Plan became effective on July 30, 2018, which was the day after the 2008 Plan expired.

Noncontrolling Interests.  Noncontrolling interests are the portion of equity in a subsidiary not attributable to a parent.  The ownership interests not held by the parent are considered noncontrolling interests.  Accordingly, we have reported noncontrolling interests in equity on the consolidated balance sheets but separate from Whitestone’s equity.  On the consolidated statements of operations and comprehensive income, subsidiaries are reported at the consolidated amount, including both the amount attributable to Whitestone and noncontrolling interests.  Consolidated statements of changes in equity are included for both quarterly and annual financial statements, including beginning balances, activity for the period and ending balances for shareholders’ equity, noncontrolling interests and total equity.

Revenue Recognition.  All leases on our properties are classified as operating leases, and the related rental income is recognized on a straight-line basis over the terms of the related leases.  Differences between rental income earned and amounts due per the respective lease agreements are capitalized or charged, as applicable, to accrued rents and accounts receivable. Percentage rents are recognized as rental income when the thresholds upon which they are based have been met.  Recoveries from tenants for taxes, insurance, and other operating expenses are recognized as revenues in the period the corresponding costs are incurred. We combine lease and nonlease components in lease contracts, which includes combining base rent, recoveries, and percentage rents into a single line item, Rental, within the consolidated statements of operations and comprehensive income. Additionally, we have tenants who pay real estate taxes directly to the taxing authority. We exclude these costs paid directly by the tenant to third parties on our behalf from revenue recognized and the associated property operating expense.

Other property income primarily includes amounts recorded in connection with management fees and lease termination fees. Pillarstone OP pays us management fees for property management, leasing and day-to-day advisory and administrative services. Their obligations are satisfied over time. Pillarstone OP is billed monthly and typically pays quarterly. Revenues are governed by the Management Agreements (as defined in Note 5). Refer to Note 5 to our accompanying consolidated financial statements for additional information regarding the Management Agreements with Pillarstone OP. Additionally, we recognize lease termination fees in the year that the lease is terminated and collection of the fee is probable. Amounts recorded within other property income are accounted for at the point in time when control of the goods or services transfers to the customer and our performance obligation is satisfied.

Cash and Cash Equivalents.  We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.  Cash and cash equivalents as of December 31, 2019 and 2018 consisted of demand deposits at commercial banks and brokerage accounts. We may have net book credit balances in our primary disbursement accounts at the end of a reporting period. We classify such credit balances as accounts payable in our consolidated balance sheets as checks presented for payment to these accounts are not payable by our banks under overdraft arrangements, and, therefore, do not represent short-term borrowings.

Marketable Securities. We classify our existing marketable equity securities as available-for-sale in accordance with the Financial Accounting Standards Board’s (“FASB”) Investments-Debt and Equity Securities guidance. These securities are carried at fair value with unrealized gains and losses reported in equity as a component of accumulated other comprehensive income or loss. The fair value of the marketable securities is determined using Level 1 inputs under FASB Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures.” Level 1 inputs represent quoted prices available in an active market for identical investments as of the reporting date. Gains and losses on securities sold are based on the specific identification method, and are reported as a component of interest, dividend and other investment income.

Real Estate

Development Properties.  Land, buildings and improvements are recorded at cost. Expenditures related to the development of real estate are carried at cost which includes capitalized carrying charges and development costs. Carrying charges (interest, real estate taxes, loan fees, and direct and indirect development costs related to buildings under construction) are capitalized as part of construction in progress. The capitalization of such costs ceases when the property, or any completed portion, becomes available for occupancy. For the year ended December 31, 2019, approximately $500,000 and $320,000 in interest expense and real estate taxes, respectively, were capitalized. For the year ended December 31, 2018, approximately $574,000 and $365,000 in interest expense and real estate taxes, respectively, were capitalized. For the year ended December 31, 2017, approximately $439,000 and $277,000 in interest expense and real estate taxes, respectively, were capitalized. 

Acquired Properties and Acquired Lease Intangibles.  We allocate the purchase price of the acquired properties to land, building and improvements, identifiable intangible assets and to the acquired liabilities based on their respective fair values at the time of purchase. Identifiable intangibles include amounts allocated to acquired out-of-market leases, the value of in-place leases and customer relationship value, if any. We determine fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends and specific market and economic conditions that may affect the property. Factors considered by management in our analysis of determining the as-if-vacant property value include an estimate of carrying costs during the expected lease-up periods considering market conditions, and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and estimates of lost rentals at market rates during the expected lease-up periods, tenant demand and other economic conditions. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related expenses. Intangibles related to out-of-market leases and in-place lease value are recorded as acquired lease intangibles and are amortized as an adjustment to rental revenue or amortization expense, as appropriate, over the remaining terms of the underlying leases. Premiums or discounts on acquired out-of-market debt are amortized to interest expense over the remaining term of such debt.

Depreciation.  Depreciation is computed using the straight-line method over the estimated useful lives of 5 to 39 years for improvements and buildings, respectively.  Tenant improvements are depreciated using the straight-line method over the life of the improvement or remaining term of the lease, whichever is shorter.

Impairment.  We review our properties for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations.  We determine whether an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of the property, with the carrying cost of the property.  If impairment is indicated, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value.  Management has determined that there has been no impairment in the carrying value of our real estate assets as of December 31, 2019.

Accrued Rents and Accounts Receivable.  Included in accrued rents and accounts receivable are base rents, tenant reimbursements and receivables attributable to recording rents on a straight-line basis. We review the collectability of charges under our tenant operating leases on a regular basis, taking into consideration changes in factors such as the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area where the property is located. With the adoption of ASC No. 842, Leases (“Topic 842”), as of January 1, 2019 we recognize an adjustment to rental revenue if we deem it probable that the receivable will not be collected. Prior to the adoption of Topic 842, we recognized an allowance for doubtful accounts and bad debt expense of the specific rents receivable. Our review of collectability under our operating leases includes any accrued rental revenues related to the straight-line method of reporting rental revenue. As of December 31, 2019 and 2018, we had an allowance for uncollectible accounts of $11.2 million and $9.7 million, respectively. For the year ending December 31, 2019, we recorded an adjustment to rental revenue in the amount of $1.5 million. For the year ending December 31, 2018 and 2017, we recorded bad debt expense in the amount of $1.4 million and $2.3 million, respectively.

Unamortized Lease Commissions and Loan Costs.  Leasing commissions are amortized using the straight-line method over the terms of the related lease agreements.  Loan costs are amortized on the straight-line method over the terms of the loans, which approximates the interest method.  Costs allocated to in-place leases whose terms differ from market terms related to acquired properties are amortized over the remaining life of the respective leases.

Prepaids and Other Assets.  Prepaids and other assets include escrows established pursuant to certain mortgage financing arrangements for real estate taxes and insurance and acquisition deposits which include earnest money deposits on future acquisitions.

Federal Income Taxes.  We elected to be taxed as a REIT under the Code beginning with our taxable year ended December 31, 1999.  As a REIT, we generally are not subject to federal income tax on income that we distribute to our shareholders.  If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax on our taxable income at regular corporate rates.  We believe that we are organized and operate in such a manner as to qualify to be taxed as a REIT, and we intend to operate so as to remain qualified as a REIT for federal income tax purposes.

State Taxes.  We are subject to the Texas Margin Tax, which is computed by applying the applicable tax rate (1% for us) to the profit margin, which, generally, will be determined for us as total revenue less a 30% standard deduction.  Although the Texas Margin Tax is not considered an income tax, FASB ASC 740, “Income Taxes” (“ASC 740”)applies to the Texas Margin Tax.  As of December 31, 2019, 2018 and 2017, we recorded a margin tax provision of $0.4 million, $0.4 million and $0.4 million, respectively.

Fair Value of Financial Instruments.  Our financial instruments consist primarily of cash, cash equivalents, accounts receivable, accounts and notes payable and investments in marketable securities.  The carrying value of cash, cash equivalents, accounts receivable and accounts payable are representative of their respective fair values due to their short-term nature.  The fair value of our long-term debt, consisting of fixed rate secured notes, variable rate secured notes and an unsecured revolving credit facility aggregate to approximately $653.7 million and $618.6 million as compared to the book value of approximately $645.9 million and $619.4 million as of December 31, 2019 and 2018, respectively. The fair value of our long-term debt is estimated on a Level 2 basis (as provided by ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”)), using a discounted cash flow analysis based on the borrowing rates currently available to us for loans with similar terms and maturities, discounting the future contractual interest and principal payments.

The fair value of our loan guarantee to Pillarstone OP is estimated on a Level 3 basis (as provided by ASC 820, “Fair Value Measurements and Disclosures”), using a probability-weighted discounted cash flow analysis based on a discount rate, discounting the loan balance. The fair value of the loan guarantee is $0.1 million and $0.3 million as compared to the book value of approximately $0.1 million and $0.3 million as of December 31, 2019 and 2018, respectively.

Disclosure about fair value of financial instruments is based on pertinent information available to management as of December 31, 2019 and 2018. Although management is not aware of any factors that would significantly affect the fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since December 31, 2019 and current estimates of fair value may differ significantly from the amounts presented herein.

Derivative Instruments and Hedging Activities. We utilize derivative financial instruments, principally interest rate swaps, to manage our exposure to fluctuations in interest rates. We have established policies and procedures for risk assessment, and the approval, reporting and monitoring of derivative financial instruments. We recognize our interest rate swaps as cash flow hedges with the effective portion of the changes in fair value recorded in comprehensive income and subsequently reclassified into earnings in the period that the hedged transaction affects earnings. Any ineffective portion of a cash flow hedge’s change in fair value is recorded immediately into earnings. Our cash flow hedges are determined using Level 2 inputs under ASC 820. Level 2 inputs represent quoted prices in active markets for similar assets or liabilities; quoted prices in markets that are not active; and model-derived valuations whose inputs are observable. As of December 31, 2019, we consider our cash flow hedges to be highly effective.

Concentration of Risk.  Substantially all of our revenues are obtained from office, warehouse and retail locations in the Austin, Chicago, Dallas-Fort Worth, Houston, Phoenix and San Antonio metropolitan areas. We maintain cash accounts in major U.S. financial institutions. The terms of these deposits are on demand to minimize risk. The balances of these accounts sometimes exceed the federally insured limits, although no losses have been incurred in connection with these deposits.

Recent Accounting Pronouncements. In May 2014, the FASB issued guidance, as amended in subsequent updates, establishing a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and superseded most of the existing revenue recognition guidance. The standard also required an entity to recognize revenue to depict the transfer of promised 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 and also required certain additional disclosures. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a modified retrospective basis beginning January 1, 2018 and have derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and have recognized the Company’s investment in Pillarstone OP under the equity method of accounting. The Company made an adjustment which decreased the Company’s accumulated deficit as of January 1, 2018 by $19.1 million. See Note 5 for further details.

In February 2016, FASB issued ASU No. 2016-2 which provided the principles for the recognition, measurement, presentation and disclosure of leases. Additional guidance and targeted improvements to Topic 842 were made through the issuance of supplementary ASUs in July 2018, December 2018 and March 2019.

Effective January 1, 2019, we adopted the new lease accounting guidance in Topic 842. As the lessee and lessor, we have elected the package of practical expedients permitted in Topic 842. Accordingly, we have accounted for our existing operating leases as operating leases under the new guidance, without reassessing (a) whether the contract contains a lease under Topic 842, (b) whether classification of the operating lease would be different in accordance with Topic 842, or (c) whether the unamortized initial direct costs before transition adjustments (as of December 31, 2018) would have met the definition of initial direct costs in Topic 842 at lease commencement. Additionally, as the lessee and lessor we will use hindsight in determining the lease term and in assessing impairment of our right-of-use assets. As a result of the adoption of the new lease accounting guidance, as the lessee, we recognized on January 1, 2019 (a) a lease liability of approximately $1.1 million, which represents the present value of the remaining lease payments of approximately $1.2 million discounted using our incremental borrowing rate of 4.5%, and (b) a right-of-use asset of approximately $1.1 million. The adoption of Topic 842 did not have a material impact to our net income and related per share amounts.

Upon adoption of Topic 842, lessees and lessors are required to apply a modified retrospective transition approach. Reporting entities are permitted to choose one of two methods to recognize and measure leases within the scope of Topic 842:

• Apply Topic 842 to each lease that existed at the beginning of the earliest comparative period presented in the financial statements as well as leases that commenced after that date. Under this method, prior comparative periods presented are adjusted. For leases that commenced prior to the beginning of the earliest comparative period presented, a cumulative-effect adjustment is recognized at that date.

• Apply the guidance to each lease that had commenced as of the beginning of the reporting period in which the entity first applies the lease standard with a cumulative-effect adjustment as of that date. Prior comparative periods would not be adjusted under this method.

We have elected an optional transition method that allows entities to initially apply Topic 842 at January 1, 2019, the date of adoption, and to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. As the lessor, we have not assessed unamortized legal costs as part of the package of practical expedients, and we will not make any adjustment to retained earnings at the date of adoption to write off unamortized legal costs. We will continue to amortize unamortized legal costs as of December 31, 2018 over the life of the respective leases. We did not have a cumulative-effect adjustment as of the adoption date. Additionally, the optional transition method does allow us to not have to apply the new standard (including disclosure requirements) to comparative periods presented. Those periods can continue to be presented in accordance with prior generally accepted accounting principles.

Topic 842 requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases and operating leases. Based on our election of the package of practical expedients, our existing commercial leases, where we are the lessor, continue to be accounted for as operating leases under the new standard. However, Topic 842 changed certain requirements regarding the classification of leases that could result in us recognizing certain long-term leases entered into or modified after January 1, 2019 as sales-type leases or finance leases, as opposed to operating leases. We will continue to monitor our leases following the adoption date to ensure that they are classified in accordance with the new lease standards.

We elected a practical expedient which allows lessors to not separate non-lease components from the lease component when the timing and pattern of transfer for the lease components and non-lease components are the same and if the lease component is classified as an operating lease. As a result, we now present all rentals and reimbursements from tenants as a single line item, Rental, within the consolidated statements of operations and comprehensive income.

We review the collectability of charges under our tenant operating leases on a regular basis, taking into consideration changes in factors such as the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area where the property is located. Each tenant is included in one of several portfolios and an allowance is calculated using the calculation methodology for the respective portfolio. With the adoption of Topic 842, we will recognize an adjustment to rental revenue if we deem it probable that the receivable will not be collected. Prior to the adoption of Topic 842, we recognized an allowance for doubtful accounts and bad debt expense of the specific rents receivable. Our review of collectability under our operating leases includes any accrued rental revenues related to the straight-line method of reporting rental revenue.

In November 2016, the FASB issued guidance requiring that the statement of cash flows explain the change during the period in the total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance effective January 1, 2018, and we have reconciled cash and cash equivalents and restricted cash and restricted cash equivalents on a retrospective basis, whereas under the previous guidance, we reported restricted cash and restricted cash equivalents under cash flows from financing activities.

In January 2017, the FASB issued guidance clarifying the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or dispositions) of assets or businesses. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a prospective basis beginning January 1, 2018 and believe the majority of our future acquisitions will qualify as asset acquisitions and the associated transaction costs will be capitalized as opposed to expensed under previous guidance. For the year ending December 31, 2019, we capitalized $0.1 million in associated transaction costs.

In February 2017, the FASB issued guidance clarifying the scope of asset derecognition guidance, adding guidance for partial sales of nonfinancial assets and clarifying recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a modified retrospective basis beginning January 1, 2018 and have derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and have recognized the Company’s investment in Pillarstone OP under the equity method of accounting. The Company made an adjustment which decreased the Company’s accumulated deficit as of January 1, 2018 by $19.1 million. See Note 5 for further details.

Stockholders' Equity Note [Abstract]

Equity

EQUITY

Under our declaration of trust, as amended, we have authority to issue up to 400 million common shares of beneficial interest, $0.001 par value per share, and up to 50 million preferred shares of beneficial interest, $0.001 par value per share.

Equity Offerings

On May 31, 2019, we entered into nine equity distribution agreements for an at-the-market equity distribution program (the “2019 equity distribution agreements”) providing for the issuance and sale of up to an aggregate of $100 million of the Company’s common shares pursuant to our Registration Statement on Form S-3 (File No. 333-225007). Actual sales will depend on a variety of factors determined by us from time to time, including (among others) market conditions, the trading price of our common shares, capital needs and our determinations of the appropriate sources of funding for us, and were made in transactions that will be deemed to be “at-the-market” offerings as defined in Rule 415 under the Securities Act. We have no obligation to sell any of our common shares and can at any time suspend offers under the 2019 equity distribution agreements or terminate the 2019 equity distribution agreements. For the year ended December 31, 2019, we sold 1,612,389 common shares under the 2019 equity distribution agreements, with net proceeds to us of approximately $21.2 million. In connection with such sales, we paid compensation of approximately $324,000 to the sales agents.

On April 25, 2017, we completed the sale of 8,018,500 common shares, including 1,018,500 common shares purchased by the underwriters upon exercise of their option to purchase additional common shares, at a public offering price per share of $13.00 (the “April 2017 Offering”). Total net proceeds from the April 2017 Offering, after deducting offering expenses, were approximately $99.9 million, which we contributed to the Operating Partnership in exchange for OP units. The Operating Partnership used the net proceeds from the April 2017 Offering to repay a portion of the 2018 Facility and for general corporate purposes, including funding a portion of the purchase price of BLVD Place and Eldorado Plaza.

On June 4, 2015, we entered into nine amended and restated equity distribution agreements (the “2015 equity distribution agreements”) for an at-the-market distribution program. Pursuant to the terms and conditions of the 2015 equity distribution agreements, we could issue and sell up to an aggregate of $50 million of our common shares pursuant to our Registration Statement on Form S-3 (File No. 333-203727), which expired on April 29, 2018. Actual sales depended on a variety of factors determined by us from time to time, including (among others) market conditions, the trading price of our common shares, capital needs and our determinations of the appropriate sources of funding for us, and were made in transactions that will be deemed to be “at-the-market” offerings as defined in Rule 415 under the Securities Act. We had no obligation to sell any of our common shares, and could at any time suspend offers under the 2015 equity distribution agreements or terminate the 2015 equity distribution agreements. For the year ended December 31, 2019 and 2018, we did not sell any common shares under the 2015 equity distribution agreements. For the year ended December 31, 2017, we sold 1,324,038 common shares under the 2015 equity distribution agreements, with net proceeds to us of approximately $18.6 million. In connection with such sales, we paid compensation of approximately $0.3 million to the sales agents.

Operating Partnership Units

Substantially all of our business is conducted through the Operating Partnership.  We are the sole general partner of the Operating Partnership.  As of December 31, 2019, we owned a 97.9% interest in the Operating Partnership.

Limited partners in the Operating Partnership holding OP units have the right to redeem their OP units for cash or, at our option, common shares at a ratio of one OP unit for one common share.  Distributions to OP unit holders are paid at the same rate per unit as distributions per share to Whitestone common shares.  As of December 31, 2019 and 2018, there were 42,279,849 and 40,585,688 OP units outstanding, respectively.  We owned 41,371,277 and 39,657,207 OP units as of December 31, 2019 and 2018, respectively. The balance of the OP units is owned by third parties, including certain trustees.  Our weighted-average share ownership in the Operating Partnership was approximately 97.7%, 97.5% and 97.0% for the years ended December 31, 2019, 2018 and 2017, respectively. For the years ended December 31, 2019 and 2018, 19,909 and 155,100 OP units, respectively, were redeemed for an equal number of common shares.

Income Tax Disclosure [Abstract]

Federal Income Taxes

FEDERAL INCOME TAXES

Federal income taxes are not provided because we intend to and believe we qualify as a REIT under the provisions of the Code and because we have distributed and intend to continue to distribute all of our taxable income to our shareholders.  Our shareholders include their proportionate taxable income in their individual tax returns.  As a REIT, we must distribute at least 90% of our real estate investment trust taxable income to our shareholders and meet certain income sources and investment restriction requirements.  In addition, REITs are subject to a number of organizational and operational requirements.  If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax on our taxable income at regular corporate tax rates.

Taxable income differs from net income for financial reporting purposes principally due to differences in the timing of recognition of interest, real estate taxes, depreciation and rental revenue. 

For federal income tax purposes, the cash distributions to shareholders are characterized as follows for the years ended December 31: 

	2019		2018		2017
Ordinary income (unaudited)	28.6	%	39.1	%	15.3	%
Return of capital (unaudited)	19.4	%	26.5	%	84.7	%

LIBOR is expected to be discontinued after 2021. A number of our current debt agreements have an interest rate tied to LIBOR. Some of these agreements provide procedures for determining an alternative base rate in the event that LIBOR is discontinued, but not all do so. Regardless, there can be no assurances as to what alternative base rates may be and whether such base rate will be more or less favorable than LIBOR and any other unforeseen impacts of the potential discontinuation of LIBOR. The Company intends to monitor the developments with respect to the potential phasing out of LIBOR after 2021 and work with its lenders to ensure any transition away from LIBOR will have minimal impact on its financial condition, but can provide no assurances regarding the impact of the discontinuation of LIBOR.

On March 22, 2019, we, through our Operating Partnership, entered into a Note Purchase and Guarantee Agreement (the “Note Agreement”) together with certain subsidiary guarantors as initial guarantor parties thereto (the “Subsidiary Guarantors”) and The Prudential Insurance Company of America and the various other purchasers named therein (collectively, the “Purchasers”) providing for the issuance and sale of $100 million of senior unsecured notes of the Operating Partnership, of which (i) $50 million are designated as 5.09% Series A Senior Notes due March 22, 2029 (the “Series A Notes”) and (ii) $50 million are designated as 5.17% Series B Senior Notes due March 22, 2029 (the “Series B Notes” and, together with the Series A Notes, the “Notes”) pursuant to a private placement that closed on March 22, 2019 (the “Private Placement”). Obligations under the Notes are unconditionally guaranteed by the Company and by the Subsidiary Guarantors.

The principal of the Series A Notes will begin to amortize on March 22, 2023 with annual principal payments of approximately $7.1 million. The principal of the Series B Notes will begin to amortize on March 22, 2025 with annual principal payments of $10.0 million. The Notes will pay interest quarterly on the 22nd day of March, June, September and December in each year until maturity.

The Operating Partnership may prepay at any time all, or from time to time part of, the Notes, in an amount not less than $1,000,000 in the case of a partial prepayment, at 100% of the principal amount so prepaid, plus a make-whole amount. The make-whole amount is equal to the excess, if any, of the discounted value of the remaining scheduled payments with respect to the Notes being prepaid over the aggregate principal amount of such Notes (as described in the Note Agreement). In addition, in connection with a Change of Control (as defined in the Note Purchase Agreement), the Operating Partnership is required to offer to prepay the Notes at 100% of the principal amount plus accrued and unpaid interest thereon.

The Note Agreement contains representations, warranties, covenants, terms and conditions customary for transactions of this type and substantially similar to the Operating Partnership’s existing senior revolving credit facility, including limitations on liens, incurrence of investments, acquisitions, loans and advances and restrictions on dividends and certain other restricted payments. In addition, the Note Agreement contains certain financial covenants substantially similar to the Operating Partnership’s existing senior revolving credit facility, including the following:

• maximum total indebtedness to total asset value ratio of 0.60 to 1.00;

• maximum secured debt to total asset value ratio of 0.40 to 1.00;

• minimum EBITDA (earnings before interest, taxes, depreciation, amortization or extraordinary items) to fixed charges ratio of 1.50 to 1.00;

• maximum other recourse debt to total asset value ratio of 0.15 to 1.00; and

• maintenance of a minimum tangible net worth (adjusted for accumulated depreciation and amortization) of $372 million plus 75% of the net proceeds from additional equity offerings (as defined therein).

In addition, the Note Agreement contains a financial covenant requiring that maximum unsecured debt not exceed the lesser of (i) an amount equal to 60% of the aggregate unencumbered asset value and (ii) the debt service coverage amount (as described in the Note Agreement). That covenant is substantially similar to the borrowing base concept contained in the Operating Partnership’s existing senior revolving credit facility.

The Note Agreement also contains default provisions, including defaults for non-payment, breach of representations and warranties, insolvency, non-performance of covenants, cross-defaults with other indebtedness and guarantor defaults. The occurrence of an event of default under the Note Agreement could result in the Purchasers accelerating the payment of all obligations under the Notes. The financial and restrictive covenants and default provisions in the Note Agreement are substantially similar to those contained in the Operating Partnership’s existing credit facility.

Net proceeds from the Private Placement were used to refinance existing indebtedness. The Notes have not been and will not be registered under the Securities Act of 1933, as amended (the “Securities Act”), and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act. The Notes were sold in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act.

On January 31, 2019, we, through our Operating Partnership, entered into an unsecured credit facility (the “2019 Facility”) with the lenders party thereto, Bank of Montreal, as administrative agent (the “Agent”), SunTrust Robinson Humphrey, as syndication agent, and BMO Capital Markets Corp., U.S. Bank National Association, SunTrust Robinson Humphrey and Regions Capital Markets, as co-lead arrangers and joint book runners. The 2019 Facility amended and restated the 2018 Facility (as defined below).

The 2019 Facility is comprised of the following three tranches:

• $250.0 million unsecured revolving credit facility with a maturity date of January 1, 2023 (the “2019 Revolver”);

• $165.0 million unsecured term loan with a maturity date of January 31, 2024 (“Term Loan A”); and

• $100.0 million unsecured term loan with a maturity date of October 30, 2022 (“Term Loan B” and together with Term Loan A, the “2019 Term Loans”).

Borrowings under the 2019 Facility accrue interest (at the Operating Partnership's option) at a Base Rate or an Adjusted LIBOR plus an applicable margin based upon our then existing leverage. As of December 31, 2019, the interest rate on the 2019 Revolver was 3.35%. The applicable margin for Adjusted LIBOR borrowings ranges from 1.40% to 1.90% for the 2019 Revolver and 1.35% to 1.90% for the 2019 Term Loans. Base Rate means the higher of: (a) the Agent’s prime commercial rate, (b) the sum of (i) the average rate quoted by the Agent by two or more federal funds brokers selected by the Agent for sale to the Agent at face value of federal funds in the secondary market in an amount equal or comparable to the principal amount for which such rate is being determined, plus (ii) 1/2 of 1.00%, and (c) the LIBOR rate for such day plus 1.00%. Adjusted LIBOR means LIBOR divided by one minus the Eurodollar Reserve Percentage. The Eurodollar Reserve Percentage means the maximum reserve percentage at which reserves are imposed by the Board of Governors of the Federal Reserve System on eurocurrency liabilities. Pursuant to the 2019 Facility, in the event of certain circumstances that result in the unavailability of LIBOR, including but not limited to LIBOR no longer being a widely recognized benchmark rate for newly originated dollar loans in the U.S. market, the Operating Partnership and the Agent will establish an alternate interest rate to LIBOR giving due consideration to prevailing market conventions and will amend the 2019 Facility to give effect to such alternate interest rate.

The 2019 Facility includes an accordion feature that will allow the Operating Partnership to increase the borrowing capacity by $200.0 million, upon the satisfaction of certain conditions. As of December 31, 2019, $374.5 million was drawn on the 2019 Facility and our unused borrowing capacity was $140.5 million, assuming that we use the proceeds of the 2019 Facility to acquire properties, or to repay debt on properties, that are eligible to be included in the unsecured borrowing base. The Company used $446.2 million of proceeds from the 2019 Facility to repay amounts outstanding under the 2018 Facility and intends to use the remaining proceeds from the 2019 Facility for general corporate purposes, including property acquisitions, debt repayment, capital expenditures, the expansion, redevelopment and re-tenanting of properties in its portfolio and working capital.

The Company, each direct and indirect material subsidiary of the Operating Partnership and any other subsidiary of the Operating Partnership that is a guarantor under any unsecured ratable debt will serve as a guarantor for funds borrowed by the Operating Partnership under the 2019 Facility. The 2019 Facility contains customary terms and conditions, including, without limitation, customary representations and warranties and affirmative and negative covenants including, without limitation, information reporting requirements, limitations on investments, acquisitions, loans and advances, mergers, consolidations and sales, incurrence of liens, dividends and restricted payments. In addition, the 2019 Facility contains certain financial covenants including the following:

• maximum total indebtedness to total asset value ratio of 0.60 to 1.00;

• maximum secured debt to total asset value ratio of 0.40 to 1.00;

• minimum EBITDA (earnings before interest, taxes, depreciation, amortization or extraordinary items) to fixed charges ratio of 1.50 to 1.00;

• maximum other recourse debt to total asset value ratio of 0.15 to 1.00; and

• maintenance of a minimum tangible net worth (adjusted for accumulated depreciation and amortization) of $372 million plus 75% of the net proceeds from additional equity offerings (as defined therein).

We serve as the guarantor for funds borrowed by the Operating Partnership under the 2019 Facility. The 2019 Facility contains customary terms and conditions, including, without limitation, affirmative and negative covenants such as information reporting requirements, maximum secured indebtedness to total asset value, minimum EBITDA (earnings before interest, taxes, depreciation, amortization or extraordinary items) to fixed charges, and maintenance of a minimum net worth. The 2019 Facility also contains customary events of default with customary notice and cure, including, without limitation, nonpayment, breach of covenant, misrepresentation of representations and warranties in a material respect, cross-default to other major indebtedness, change of control, bankruptcy and loss of REIT tax status.

On November 7, 2014, we, through our Operating Partnership, entered into an unsecured revolving credit facility (the “2014 Facility”) with the lenders party thereto, with BMO Capital Markets Corp., Wells Fargo Securities, LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and U.S. Bank, National Association, as co-lead arrangers and joint book runners, and Bank of Montreal, as administrative agent (the “Agent”). The 2014 Facility amended and restated our previous unsecured revolving credit facility. On October 30, 2015, we, through our Operating Partnership, entered into the First Amendment to the 2014 Facility (the “First Amendment”) with the guarantors party thereto, the lenders party thereto and the Agent. We refer to the 2014 Facility, as amended by the First Amendment, as the “2018 Facility.”

Pursuant to the First Amendment, the Company made the following amendments to the 2014 Facility:

• extended the maturity date of the $300 million unsecured revolving credit facility under the 2014 Facility (the “2018 Revolver”) to October 30, 2019 from November 7, 2018;

• converted $100 million of outstanding borrowings under the Revolver to a new $100 million unsecured term loan under the 2014 Facility (“Term Loan 3”) with a maturity date of October 30, 2022;

• extended the maturity date of the first $50 million unsecured term loan under the 2014 Facility (“Term Loan 1”) to October 30, 2020 from February 17, 2017; and

• extended the maturity date of the second $50 million unsecured term loan under the 2014 Facility (“Term Loan 2” and together with Term Loan 1 and Term Loan 3, the “2018 Term Loans”) to January 29, 2021 from November 7, 2019.

Borrowings under the 2018 Facility accrued interest (at the Operating Partnership's option) at a Base Rate or an Adjusted LIBOR plus an applicable margin based upon our then existing leverage. The applicable margin for Adjusted LIBOR borrowings ranged from 1.40% to 1.95% for the 2018 Revolver and 1.35% to 2.25% for the 2018 Term Loans. Base Rate means the higher of: (a) the Agent’s prime commercial rate, (b) the sum of (i) the average rate quoted by the Agent by two or more federal funds brokers selected by the Agent for sale to the Agent at face value of federal funds in the secondary market in an amount equal or comparable to the principal amount for which such rate is being determined, plus (ii) 1/2 of 1.00%, and (c) the LIBOR rate for such day plus 1.00%. Adjusted LIBOR means LIBOR divided by one minus the Eurodollar Reserve Percentage. The Eurodollar Reserve Percentage means the maximum reserve percentage at which reserves are imposed by the Board of Governors of the Federal Reserve System on eurocurrency liabilities.

Proceeds from the 2018 Facility were used for general corporate purposes, including property acquisitions, debt repayment, capital expenditures, the expansion, redevelopment and re-tenanting of properties in our portfolio and working capital.

On May 26, 2017, we, through our subsidiary, Whitestone BLVD Place LLC, a Delaware limited liability company, issued a $80.0 million promissory note to American General Life Insurance Company (the “BLVD Note”). The BLVD Note has a fixed interest rate of 3.72% and a maturity date of June 1, 2027. Proceeds from the BLVD Note were used to fund a portion of the purchase price of the acquisition of BLVD Place.

As of December 31, 2019, our $171.4 million in secured debt was collateralized by eight properties with a carrying value of $270.4 million.  Our loans contain restrictions that would require the payment of prepayment penalties for the acceleration of outstanding debt and are secured by deeds of trust on certain of our properties and by assignment of the rents and leases associated with those properties.  In 2018, we were not in compliance with respect to the tangible Net Worth covenant as defined in the 2018 Facility and had received two waivers in 2018. Had we been unable to obtain a waiver or other suitable relief from the lenders under the 2018 Facility, an Event of Default (as defined in the 2018 Facility) would have occurred, permitting the lenders holding a majority of the commitments under the 2018 Facility to, among other things, accelerate the outstanding indebtedness, which would make it immediately due and payable. The 2019 Facility and the Notes contain a similar tangible Net Worth covenant that resets at a new threshold and changes the definition of Net Worth to add back accumulated depreciation. However, we can make no assurances that we will be in compliance with these covenants or other covenants under the 2019 Facility or the Notes in future periods or, if we are not in compliance, that we will be able to obtain a waiver. As of December 31, 2019, we were in compliance with all loan covenants.

Scheduled maturities of our outstanding debt as of December 31, 2019 were as follows (in thousands):

⁽¹⁾   As of December 31, 2019, we had one loan totaling $109.5 million which bore interest at a floating rate.  The variable interest rate payments are based on LIBOR plus 1.40% to LIBOR plus 1.90%, which reflects our new interest rates under the 2019 Facility.  The information in the table above reflects our projected interest rate obligations for the floating rate payments based on one-month LIBOR as of December 31, 2019, of 1.76%.

⁽²⁾  The unused commitment fees on the 2019 Facility, payable quarterly, are based on the average daily unused amount of the 2019 Facility. The fees are 0.20% for facility usage greater than 50% or 0.25% for facility usage less than 50%. The information in the table above reflects our projected obligations for the 2019 Facility based on our December 31, 2019 balance of $374.5 million.

On December 8, 2016, we, through our Operating Partnership, entered into a Contribution Agreement (the “Contribution Agreement”) with Pillarstone OP and Pillarstone Capital REIT (“Pillarstone REIT”) pursuant to which we contributed all of the equity interests in four of our wholly-owned subsidiaries: Whitestone CP Woodland Ph. 2, LLC, a Delaware limited liability company (“CP Woodland”); Whitestone Industrial-Office, LLC, a Texas limited liability company (“Industrial-Office”); Whitestone Offices, LLC, a Texas limited liability company (“Whitestone Offices”); and Whitestone Uptown Tower, LLC, a Delaware limited liability company (“Uptown Tower,” and together with CP Woodland, Industrial-Office and Whitestone Offices, the “Entities”) that own 14 non-core properties that do not fit our Community Centered Property^® strategy (the “Pillarstone Properties”), to Pillarstone OP for aggregate consideration of approximately $84 million, consisting of (1) approximately $18.1 million of Class A units representing limited partnership interests in Pillarstone OP (“Pillarstone OP Units”), issued at a price of $1.331 per Pillarstone OP Unit; and (2) the assumption of approximately $65.9 million of liabilities, consisting of (a) approximately $15.5 million of our liability under the 2018 Facility (as defined in Note 9); (b) an approximately $16.3 million promissory note of Uptown Tower under the Loan Agreement, dated as of September 26, 2013, between Uptown Tower, as borrower, and U.S. Bank, National Association, as successor to Morgan Stanley Mortgage Capital Holdings LLC, as lender; and (c) an approximately $34.1 million promissory note (the “Industrial-Office Promissory Note”) of Industrial-Office issued under the Loan Agreement, dated as of November 26, 2013 (the “Industrial-Office Loan Agreement”), between Industrial-Office, as borrower, and Jackson National Life Insurance Company, as lender (collectively, the “Contribution”).

In connection with the Contribution, (1) with respect to each Pillarstone Property (other than Uptown Tower), Whitestone TRS, Inc., a subsidiary of the Company (“Whitestone TRS”), entered into a Management Agreement with the Entity that owns such Pillarstone Property and (2) with respect to Uptown Tower, Whitestone TRS entered into a Management Agreement with Pillarstone OP (collectively, the “Management Agreements”). Pursuant to the Management Agreements with respect to each Pillarstone Property (other than Uptown Tower), Whitestone TRS agreed to provide certain property management, leasing and day-to-day advisory and administrative services to such Pillarstone Property in exchange for (x) a monthly property management fee equal to 5.0% of the monthly revenues of such Pillarstone Property and (y) a monthly asset management fee equal to 0.125% of GAV (as defined in each Management Agreement as, generally, the purchase price of the respective Pillarstone Property based upon the purchase price allocations determined pursuant to the Contribution Agreement, excluding all indebtedness, liabilities or claims of any nature) of such Pillarstone Property. Pursuant to the Management Agreement with respect to Uptown Tower, Whitestone TRS agreed to provide certain property management, leasing and day-to-day advisory and administrative services to Pillarstone OP in exchange for (x) a monthly property management fee equal to 3.0% of the monthly revenues of Uptown Tower and (y) a monthly asset management fee equal to 0.125% of GAV of Uptown Tower. The initial term of each Management Agreement expired on December 31, 2017, after which each Management Agreement became automatically renewable on a month to month basis; provided that each Management Agreement can be terminated by either party thereto upon not less than thirty days’ prior written notice to the other party. None of the Management Agreements had been terminated as of December 31, 2019.

In connection with the Contribution, on December 8, 2016, the Operating Partnership entered into a Tax Protection Agreement with Pillarstone REIT and Pillarstone OP pursuant to which Pillarstone OP agreed to indemnify the Operating Partnership for certain tax liabilities resulting from its recognition of income or gain prior to December 8, 2021 if such liabilities result from a transaction involving a direct or indirect taxable disposition of all or a portion of the Pillarstone Properties or if Pillarstone OP fails to maintain and allocate to the Operating Partnership for taxation purposes minimum levels of liabilities as specified in the Tax Protection Agreement, the result of which causes such recognition of income or gain and the Company incurs taxes that must be paid to maintain its REIT status for federal income tax purposes.

As of December 31, 2019, we owned approximately 81.4% of the total outstanding units of Pillarstone OP. Additionally, certain of our officers and trustees serve as officers and trustees of Pillarstone REIT. In connection with the Contribution, in December 2016, we determined that we were the primary beneficiary of Pillarstone OP, through our power to direct the activities of Pillarstone OP, additional working capital required by Pillarstone OP under an OP Unit purchase agreement and our obligation to absorb losses and receive benefits based on our ownership percentage. Accordingly, we accounted for Pillarstone OP as a VIE and fully consolidated it in our consolidated financial statements for the year ended December 31, 2016 and in the subsequent periods.

In November 2017, we received a comment letter from the Staff of the Division of Corporation Finance of the SEC (the “Staff”) relating to our Annual Report on Form 10-K for the year ended December 31, 2016. In their letter, the Staff requested that we provide them with an analysis to support our determination that Pillarstone OP is a VIE of which we are the primary beneficiary and that Pillarstone OP should be consolidated in our financial statements in accordance with GAAP. In response to the Staff’s comment, we provided the Staff with our analysis of our accounting and financial reporting obligations relating to our interest in Pillarstone OP. After communicating our analysis and conclusions to the Staff and responding to additional questions from the Staff relating to this matter, the Staff did not object to or otherwise take exception to our initial determinations at the time of the consummation of the Contribution in December 2016 but provided a verbal reminder that the determination of the primary beneficiary of a VIE should be continually reassessed, noting that the initial terms of the Management Agreements expired in December 2017, and suggesting that we consider pre-clearing future accounting treatment of Pillarstone OP with the Staff of the Office of the Chief Accountant (“OCA”).

In connection with the preparation and review of the Company’s financial statements for the quarter ended March 31, 2018, the Company concluded, after consultation with the Company’s outside advisors, that it would be prudent to seek the pre-clearance from the Staff of the SEC’s Office of the Chief Accountant (“OCA”) of the proposed treatment of Pillarstone OP in the Company’s financial statements for such quarter. Accordingly, in April 2018, the Company submitted a letter to the OCA seeking their concurrence with the Company’s determinations that it maintained its status as the primary beneficiary of Pillarstone OP and, accordingly, should continue to consolidate Pillarstone OP in its financial statements for the quarter ended March 31, 2018 in accordance with GAAP. After further correspondence, including telephonic meetings between the Company, its advisors and the OCA, the OCA informed the Company that it objected to the conclusions that the Company was the primary beneficiary of Pillarstone OP and was required to consolidate it in the Company’s financial statements since the Contribution in December 2016 and during the subsequent periods.

After consideration of the OCA’s objection to the Company’s original accounting, the Company determined that the correct accounting treatment was to apply certain industry specific accounting guidance applicable to real estate transactions, ASC 360-20, the profit sharing method, which required the Company to continue to recognize the underlying assets and liabilities associated with the Contribution in the Company’s financial statements, and revised its accounting treatment accordingly. Management evaluated the quantitative and qualitative materiality of the errors and concluded that the difference between applying ASC 360-20 and the consolidation of Pillarstone OP under the VIE guidance was not material to the financial statements of any period presented through December 31, 2017. As a result, the Company elected to correct them in future financial statements, beginning with the consolidated financial statements as and for the period ended June 30, 2018 and in the accompanying prior period consolidated financial statements included in the Company’s Quarterly Report on Form 10-Q for the period ended June 30, 2018.

On January 1, 2018, the Company adopted ASU 2014-09 (“Topic 606”), as subsequently amended, using the modified retrospective method and applied Topic 606 to those contracts that were not completed as of January 1, 2018. Topic 606 added a new section, ASC 610, “Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets,” which effectively superseded industry specific accounting guidance applicable to real estate transactions.

As a result of the adoption of Topic 606 and ASC 610, the Company derecognized the underlying assets and liabilities associated with the Contribution as of January 1, 2018 and recognized the Company’s investment in Pillarstone OP under the equity method for the periods after December 31, 2017.

The table below presents the real estate partnership investment in which the Company held an ownership interest (in thousands):

On October 8, 2019, Pillarstone OP, through an indirect wholly owned subsidiary, Whitestone Industrial-Office, LLC, sold a portfolio of three properties in Houston, Texas to an unaffiliated third party for $39.7 million in cash. Pillarstone OP used the net proceeds to make a large distribution to Whitestone of $5.4 million after customary closing deductions, to pay off mortgage debt on the three properties, and pay off the remaining $5.7 million of its $15.5 million loan from Whitestone. Included in 2019 equity in earnings from real estate partnership is a $13.8 million gain related to this sale.

On December 27, 2018, Pillarstone OP, through an indirect wholly owned subsidiary, Whitestone Industrial-Office, LLC, sold a portfolio of three properties in Houston, Texas to an unaffiliated third party for $15.8 million in cash.

Description of Business and Nature of Operations

DESCRIPTION OF BUSINESS AND NATURE OF OPERATIONS

Whitestone REIT (“Whitestone”) was formed as a real estate investment trust, pursuant to the Texas Real Estate Investment Trust Act on August 20, 1998.  In July 2004, we changed our state of organization from Texas to Maryland pursuant to a merger where we merged directly with and into a Maryland real estate investment trust formed for the sole purpose of the reorganization and the conversion of each of our outstanding common shares of beneficial interest of the Texas entity into 1.42857 common shares of beneficial interest of the Maryland entity.  We serve as the general partner of Whitestone REIT Operating Partnership, L.P. (the “Operating Partnership” or “WROP” or “OP”), which was formed on December 31, 1998 as a Delaware limited partnership.  We currently conduct substantially all of our operations and activities through the Operating Partnership.  As the general partner of the Operating Partnership, we have the exclusive power to manage and conduct the business of the Operating Partnership, subject to certain customary exceptions.  As of December 31, 2019, 2018 and 2017, we owned 58, 57, and 73 commercial properties, respectively, in and around Austin, Chicago, Dallas-Fort Worth, Houston, Phoenix and San Antonio.

As of December 31, 2019, these properties consist of:

Consolidated Operating Portfolio

• 53 wholly-owned properties that meet our Community Centered Properties^® strategy; and

• five parcels of land held for future development.

As of December 31, 2019, we, through our equity-method investment in Pillarstone Capital REIT Operating Partnership LP (“Pillarstone” or “Pillarstone OP”), owned a majority interest in eight properties that do not meet our Community Centered Property® strategy containing approximately 0.9 million square feet of GLA (the “Pillarstone Properties”). We own 81.4% of the total outstanding units of Pillarstone OP, which we account for using the equity method. We also manage the day-to-day operations of Pillarstone OP.

COMMITMENTS AND CONTINGENCIES

We are subject to various legal proceedings and claims that arise in the ordinary course of business.  These matters are generally covered by insurance.  While the resolution of these matters cannot be predicted with certainty, management believes the final outcome of such matters will not have a material adverse effect on our financial position, results of operations, cash flows or liquidity.

On April 16, 2019, a purported shareholder of the Company filed a class action lawsuit in the United States District Court for the Southern District of Texas against the Company, James C. Mastandrea, and David K. Holeman, entitled Clark v. Whitestone REIT, et al., Case 4:19-cv-01379.  A second class action lawsuit was filed but was consolidated into the Clark case. The complaint alleges, among other things, that the Company and the individual defendants violated certain federal securities laws by making materially false and misleading statements in the Company’s Forms 10-Q for the first three quarterly periods of the year ended December 31, 2018 as a result of the accounting errors that required the restatement of our consolidated financial statements for the first three quarterly periods of the year ended December 31, 2018.  The purported class period runs from May 9, 2018 through February 27, 2019. The complaint sought, among other things, compensatory damages in an amount to be proven at trial, plus interest, attorneys’ fees, and costs.  In August 2019, the complainants in these purported class actions withdrew their claims, and the Court issued an order dismissing them with prejudice. On July 17, 2019, the Company received a demand letter from a purported shareholder containing allegations similar to those contained in the purported class actions. Subsequent to the dismissal of the purported class actions, in September 2019, counsel for the purported shareholder withdrew its demand.

On December 12, 2017, a property owner that owns a land parcel adjacent to a Whitestone property filed suit against Whitestone Pinnacle of Scottsdale - Phase II, LLC (“Whitestone Pinnacle”)alleging breach of contract and resulting in the delay of the construction of the their assisted living facility. In May 2019, the claimant amended their report of damages and seeks approximately $2.7 million in restitution from Whitestone Pinnacle. The Company intends to vigorously defend the matter as it believes that these claims are without merit and that it has substantial legal and factual defenses to the claims and allegations contained in the complaint. Based upon the present status of this matter, the Company does not believe it is probable that a loss will be incurred. Accordingly, the Company has not recorded a charge as a result of this action.
