WHITESTONE REIT AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2017

(Unaudited)

The use of the words “we,” “us,” “our,” “Company” or “Whitestone” refers to Whitestone REIT and our consolidated subsidiaries, except where the context otherwise requires.

1.  INTERIM FINANCIAL STATEMENTS

The consolidated financial statements included in this report are unaudited; however, amounts presented in the consolidated balance sheet as of December 31, 2016 are derived from our audited consolidated financial statements as of that date.  The unaudited financial statements as of and for the period ended March 31, 2017 have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information on a basis consistent with the annual audited consolidated financial statements and with the instructions to Form 10-Q.

The consolidated financial statements presented herein reflect all adjustments which, in the opinion of management, are necessary for a fair presentation of the financial position of Whitestone and our subsidiaries as of March 31, 2017, and the results of operations for the three month periods ended March 31, 2017 and 2016, the consolidated statements of changes in equity for the three month period ended March 31, 2017 and cash flows for the three month periods ended March 31, 2017 and 2016.  All of these adjustments are of a normal recurring nature.  The results of operations for the interim periods are not necessarily indicative of the results expected for a full year.  The statements should be read in conjunction with the audited consolidated financial statements and the notes thereto which are included in our Annual Report on Form 10-K for the year ended December 31, 2016.

Business.  Whitestone was formed as a real estate investment trust (“REIT”) 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 REIT formed for the sole purpose of the reorganization and the conversion of each of the 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”), 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 March 31, 2017 and December 31, 2016, Whitestone owned or held a majority interest in 69 commercial properties in and around Austin, Chicago, Dallas-Fort Worth, Houston, Phoenix and San Antonio.

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 March 31, 2017 and December 31, 2016, 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. We also consolidate a variable interest entity (“VIE”) when we are determined to be the primary beneficiary. Determination of the primary beneficiary is based on whether an entity has (1) the power to direct activities that most significantly impact the economic performance of the VIE and (2) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Our determination of the primary beneficiary considers all relationships between us and the VIE, including management and other contractual agreements. See Note 6 for additional disclosure on our VIE.

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 period. 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.

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.

WHITESTONE REIT AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2017

(Unaudited)

Use of Estimates.   The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities as of 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 period amounts in the accompanying consolidated financial statements in order to be consistent with the current period presentation. 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 (See Note 7), 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. As a result, these amounts are reported in the consolidated statements of cash flows under cash flows from financing activities as change in restricted cash.

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.

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 (loss) and subsequently reclassified into earnings in the period that the hedged transaction affects earnings. Any ineffective portion of a cash flow hedges' 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 March 31, 2017, we consider our cash flow hedges to be highly effective.

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 three months ended March 31, 2017, approximately $72,000 and $29,000 in interest expense and real estate taxes, respectively, were capitalized, and for the three months ended March 31, 2016, approximately $27,000 and $16,000 in interest expense and real estate taxes, respectively, were capitalized.

Real Estate Held for Sale and Discontinued Operations. We consider a commercial property to be held for sale when it meets all of the criteria established under ASC 205, “Presentation of Financial Statements.” For commercial properties classified as held for sale, assets and liabilities are presented separately for all periods presented.

WHITESTONE REIT AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2017

(Unaudited)

In accordance with ASC 205,a discontinued operation may include a component of an entity or a group of components of an entity. A disposal of a component of an entity or a group of components of an entity is reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results when the component of an entity or group of components of an entity is classified as held for sale, disposed of by sale or disposed of other than by sale, respectively. In addition, ASC 205 requires us to provide additional disclosures about both discontinued operations and the disposal of an individually significant component of an entity that does not meet the criteria for a discontinued operation.

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 2008 Long-Term Equity Incentive Ownership Plan (the “2008 Plan”).  The vast majority of the 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 $2,451,000 and $2,025,000 in share-based compensation for the three months ended March 31, 2017 and 2016, respectively.

Noncontrolling Interests.  Noncontrolling interests is 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, subsidiaries are reported at the consolidated amount, including both the amount attributable to Whitestone and noncontrolling interests.  The consolidated statement of changes in equity is included for quarterly financial statements, including beginning balances, activity for the period and ending balances for shareholders' equity, noncontrolling interests and total equity.

See our Annual Report on Form 10-K for the year ended December 31, 2016 for further discussion on significant accounting policies.

Recent Accounting Pronouncements.  In February 2016, the FASB issued guidance requiring lessees to recognize a lease liability and a right-of-use asset for all leases. Lessor accounting will remain largely unchanged with the exception of changes related to costs which qualify as initial direct costs. The guidance will also require new qualitative and quantitative disclosures to help financial statement users better understand the timing, amount and uncertainty of cash flows arising from leases. This guidance will be effective for reporting periods beginning on or after December 15, 2018, with early adoption permitted. We are currently evaluating the impact of this guidance and its impact on our consolidated financial statements.

In March 2016, the FASB issued guidance simplifying the accounting for share-based payment transactions, including the income tax consequences, balance sheet classification of awards and the classification on the statement of cash flows. We have adopted this guidance as of January 1, 2017. The main provision regarding excess tax benefits did not have an impact on our consolidated financial statements due to our status as a REIT for taxation purposes. We have elected to continue estimating the number of shares expected to vest in order to determine compensation cost, and we will continue to classify cash paid by us for employee taxes when common shares were repurchased to cover minimum statutory requirements as financing activity.

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 will become effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We are currently evaluating the impact of this guidance and its impact on our consolidated financial statements.

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 disposals) of assets or businesses. This guidance will become effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years.

⁽⁶⁾  Promissory note includes an interest rate swap that fixed the interest rate at 5.72% for the duration of the term. As part of our acquisition of Paradise Plaza in August 2012, we recorded a discount on the note of $1.3 million, which amortizes into interest expense over the life of the loan and results in an imputed interest rate of 4.13%.

⁽⁷⁾  Unsecured line of credit includes certain Pillarstone Properties.

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, 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 “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 “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 “Term Loans”) to January 29, 2021 from November 7, 2019.

Borrowings under the 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. The applicable margin for Adjusted LIBOR borrowings ranges from 1.40% to 1.95% for the Revolver and 1.35% to 2.25% for the 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.

We serve as the guarantor for funds borrowed by the Operating Partnership under the Facility. The 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 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.

The Facility includes an accordion feature that will allow the Operating Partnership to increase the borrowing capacity to $700 million, upon the satisfaction of certain conditions. As of March 31, 2017, $397.6 million was drawn on the Facility, and our remaining borrowing capacity was $102.4 million. Proceeds from the Facility were used for general corporate purposes, including property acquisitions, debt repayment, capital expenditures, the expansion, redevelopment and retenanting of properties in our portfolio and working capital. We intend to use the additional proceeds from the Facility for general corporate purposes, including property acquisitions, debt repayment, capital expenditure, the expansion, redevelopment and re-tenanting of properties in our portfolio and working capital.

On December 8, 2016, in connection with the Contribution, the Operating Partnership entered into the Second Amendment to the Facility and Reaffirmation of Guaranties (the “Second Amendment”) with Pillarstone, 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 Facility) and Guarantors under the Facility and their respective Pillarstone Properties were each permitted to remain an Eligible Property (as defined in the Facility) and be included in the Borrowing Base (as defined in the Facility) under the Facility.

As of March 31, 2017, Pillarstone accounted for approximately $15.5 million of the total amount drawn on the Facility.

As of March 31, 2017, our $158.4 million in secured debt was collateralized by 19 properties with a carrying value of $189.0 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.  As of March 31, 2017, we were in compliance with all loan covenants.

On November 19, 2015, we, through our Operating Partnership, entered into an interest rate swap with Bank of Montreal that fixed the LIBOR portion of Term Loan 3 under the Facility at 1.725%.

See Note 7 for additional information regarding the Facility. The swap began on November 30, 2015 and will mature on October 28, 2022. We have designated the interest rate swap as a cash flow hedge with the effective portion of the changes in fair value to be recorded in comprehensive income (loss) and subsequently reclassified into earnings in the period that the hedged transaction affects earnings. The ineffective portion of the change in fair value, if any, will be recognized directly in earnings.

⁽¹⁾  There was no ineffective portion of our interest rate swaps to recognize in earnings for the three months ended March 31, 2017 and 2016.

9.  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 common shares and the net income attributable to noncontrolling 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 common shares and the net income attributable to noncontrolling interests by the weighted average number of common shares including any dilutive unvested restricted common shares.

Certain of our performance-based restricted common shares are considered participating securities that require the use of the two-class method for the computation of basic and diluted earnings per share.  During the three months ended March 31, 2017 and 2016, 1,099,827 and 491,023 OP units, respectively, were excluded from the calculation of diluted earnings per share because their effect would be anti-dilutive.

For the three months ended March 31, 2017 and 2016, distributions of $95,000 and $155,000, respectively, were made to holders of certain restricted common shares, $4,000 and $0, respectively, of which were charged against earnings. See Note 12 for information related to restricted common shares under the 2008 Plan.

10. INCOME TAXES

With the exception of our taxable REIT subsidiaries, federal income taxes are generally not provided because we intend to and believe we qualify as a REIT under the provisions of the Internal Revenue Code (the “Code”) and because we have distributed and intend to continue to distribute all of our taxable income to our shareholders.  As a REIT, we must distribute at least 90% of our REIT 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 (including any applicable alternative minimum tax) on our taxable income at regular corporate tax rates.

Income earned by our taxable REIT subsidiary, Whitestone Davenport TRS LLC (“Davenport TRS”), is subject to federal income tax. For the three months ended March 31, 2016, we recognized $45,000 in income tax expense related to Davenport TRS taxable year. Davenport TRS was dissolved in the fourth quarter of 2016.

We are subject to the Texas Margin Tax, which is computed by applying the applicable tax rate (0.75% 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” applies to the Texas Margin Tax.  For the three months ended March 31, 2017 and 2016, we recognized approximately $79,000 and $114,000 in margin tax provision, respectively.

11.  EQUITY

Common Shares

Under our declaration of trust, as amended, we have authority to 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.

Actual sales will depend on a variety of factors to be 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 will be 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 2015 equity distribution agreements or terminate the 2015 equity distribution agreements. During the three months ended March 31, 2017, we sold 390,726 common shares under the 2015 equity distribution agreements, with net proceeds to us of approximately $5.3 million. In connection with such sales, we paid compensation of approximately $0.1 million to the sales agents. We did not sell any common shares under the 2015 equity distribution agreements during the three months ended March 31, 2016.

Operating Partnership Units

Substantially all of our business is conducted through our Operating Partnership.  We are the sole general partner of the Operating Partnership.  As of March 31, 2017, we owned a 96.4% 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 holders of Whitestone common shares.  As of March 31, 2017 and December 31, 2016, there were 30,845,917 and 30,450,377 OP units outstanding, respectively.  We owned 29,750,636 and 29,347,741 OP units as of March 31, 2017 and December 31, 2016, respectively. The balance of the OP units is owned by third parties, including certain members of our board of trustees.  Our weighted average share ownership in the Operating Partnership was approximately 96.4% and 98.2% for the three months ended March 31, 2017 and 2016, respectively. During the three months ended March 31, 2017 and 2016, 7,355 and 12,101 OP units, respectively, were redeemed for an equal number of common shares.

Distributions

12.  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 common shares and/or OP 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 51 of our employees. The modified time-based shares will vest 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. If the performance targets are not met prior to December 31, 2018, any unvested performance-based restricted common shares and restricted common share units will be forfeited.

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.

A summary of the share-based incentive plan activity as of and for the three months ended March 31, 2017 is as follows:

	Shares		Weighted Average Grant Date Fair Value
Non-vested at January 1, 2017	2,044,334		$	14.48
Granted	23,200		13.91
Vested	(102,448	)	14.63

	Shares Granted			Shares Vested
	Non-Vested Shares Issued	Weighted Average Grant-Date Fair Value		Vested Shares		Total Vest-Date Fair Value
						(in thousands)
Three Months Ended March 31, 2017	23,200	$	13.91	(102,448	)	$	1,499

Year Ended December 31, 2014	2,058,930	14.40		(133,774	)	1,721

Total compensation recognized in earnings for share-based payments was $2,451,000 and $2,025,000 for the three months ended March 31, 2017 and 2016, respectively.

Based on our current financial projections, we expect approximately 82%of the unvested awards to vest over the next24months. As ofMarch 31, 2017, there was approximately $3.2 million in unrecognized compensation cost related to outstanding non-vested performance-based shares, which are expected to vest over a period of 24 months and approximately $5.4 million in unrecognized compensation cost related to outstanding non-vested time-based shares, which are expected to be recognized over a period of approximately 12 months beginning on April 1, 2017.

We expect to record approximately $8.6 millionin non-cash share-based compensation expense in 2017 and$2.5 millionsubsequent to 2017. The unrecognized share-based compensation cost is expected to vest over a weighted average period of16months.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.

13. GRANTS TO TRUSTEES

On December 21, 2016, each of our four independent trustees and one trustee emeritus was granted 1,500 common shares, which vested immediately. The 7,500 common shares granted to our trustees had a grant date fair value of $14.07 per share. On December 21, 2016, two of our independent trustees elected to receive a total of 3,128 common shares with a grant date fair value of $14.07 in lieu of cash for board fees. The fair values of the shares granted were determined using quoted prices available on the date of grant.

14. SEGMENT INFORMATION

Historically, our management has not differentiated results of operations by property type or location and, therefore, does not present segment information.

15. REAL ESTATE

Property acquisitions. On September 30, 2016, we acquired La Mirada and Seville, properties that meet our Community Centered Property™ strategy, for 621,053 OP units and $60.7 million in cash and net prorations. The OP units are redeemable for cash or, at our option, Whitestone REIT common shares on a one-for-one basis, subject to certain restrictions. La Mirada, a 147,209 square foot property, was 90% leased at the time of purchase. Seville, a 90,042 square foot property, was 88% leased at the time of purchase. Both properties are located in Scottsdale, Arizona.

Development properties. As of March 31, 2017, we had substantially completed construction at our Pinnacle of Scottsdale Phase II property. As of March 31, 2017, we had incurred approximately $4.5 million in construction costs, including approximately $0.5 million in previously capitalized interest and real estate taxes. The 27,063 square foot Community Centered Property was 44% leased as of March 31, 2017 and is located in Scottsdale, Arizona, and adjacent to Pinnacle of Scottsdale.

On December 31, 2016, we had substantially completed construction at our Shops at Starwood Phase III property. As of March 31, 2017, we had incurred approximately $7.6 million in construction costs, including approximately $0.8 million in previously capitalized interest and real estate taxes. The 35,351 square foot Community Centered Property was 50% leased as of March 31, 2017 and is located in Frisco, Texas, a northern suburb of Dallas, Texas, and adjacent to Shops at Starwood.

Property dispositions. On March 3, 2016, we completed the sale of Brookhill, located in Houston, Texas, for $3.1 million. This disposition was pursuant to our strategy of recycling capital by disposing of non-core properties, primarily properties that we owned at the time our current management team assumed the management of the Company, that do not fit our Community Centered Property™ strategy. We recorded a gain on sale of $1.9 million. The sale was structured as a like-kind exchange within the meaning of Section 1031 of the Code and sales proceeds were deposited into a Section 1031 exchange escrow account with a qualified intermediary and subsequently distributed for general corporate purposes. We have not included Brookhill in discontinued operations as it did not meet the definition of discontinued operations.

On February 17, 2016, we completed the sale of approximately 0.5 acres of our 4.5 acre Pinnacle Phase II development parcel, located in Scottsdale, Arizona, for $1.1 million. We recorded a gain on sale of $1.0 million.

16. SUBSEQUENT EVENTS

Pending Acquisitions

On April 19, 2017, we announced the pending acquisitions of two retail centers located at BLVD Place in Houston, Texas and Eldorado Plaza in McKinney, Texas, respectively, each of which is a property that meets our Community Centered Property™ strategy, for an aggregate purchase price of $204.6 million in cash. On May 3, 2017, we acquired Eldorado Plaza. Pursuant to the purchase agreement governing the acquisition of BLVD Place, we expect the closing of BLVD Place to occur in May 2017.

The closing of BLVD Place is not subject to a financing condition. We funded the purchase price of Eldorado Plaza and related transaction expenses through a combination of net proceeds from the April Offering (as defined below) and borrowings under our Facility. We expect to fund the purchase price of the acquisition of BLVD Place and related transaction expenses through a combination of net proceeds from the April Offering (as defined below), and $80 million of asset level mortgage financing (the “BLVD Financing”). We are currently negotiating the terms of the BLVD Financing with potential lenders, however we have not yet entered into a binding commitment letter or definitive loan documents and there can be no assurance that we will obtain the BLVD Financing on the terms we anticipate or at all. The consummation of the BLVD Place acquisition is not contingent on obtaining the BLVD Financing and, in the event we do not obtain the BLVD Financing, we expect to fund the purchase price of the BLVD Place acquisition through a combination of net proceeds from the April Offering, as discussed below, and borrowings under our Facility. In addition, pursuant to the purchase agreements governing the acquisition of BLVD Place, the closing of BLVD Place is subject to the satisfaction or waiver of certain customary closing conditions. There can be no assurance that the closing of the acquisition of BLVD Place will occur in accordance with the anticipated timeline or at all. See “Risk Factors - There can be no assurance that the acquisition of BLVD Place will be consummated or that the BLVD Financing will be obtained in accordance with the anticipated timing or at all.”

April Offering

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 purchase price of $12.48 per share (the “April Offering”). Total net proceeds from the April 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 intends to use the net proceeds from the April Offering initially to repay a portion of outstanding indebtedness under the Facility, which amounts will then become available for future borrowings, including the funding of a portion of the purchase price of the acquisitions of Eldorado Plaza and BLVD Place or for general corporate purposes.

Item 2.  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 unaudited consolidated financial statements and the notes thereto included in this Quarterly Report on Form 10-Q (the “Report”), and the consolidated financial statements and the notes thereto and “Management's Discussion and Analysis of Financial Condition and Results of Operations” contained in our Annual Report on Form 10-K for the year ended December 31, 2016.  For more detailed information regarding the basis of presentation for the following information, you should read the notes to the unaudited consolidated financial statements included in this Report.

This Report contains forward-looking statements within the meaning of the federal securities laws, including discussion and analysis of our financial condition, pending acquisitions and the impact of such acquisitions on our financial condition and results of operations, 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 are 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 Report.  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 Report include:

• the imposition of federal taxes if we fail to qualify as a 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 in Texas, Arizona or Illinois;

• increases in interest rates and operating costs;

• availability and terms of capital and financing, both to fund our operations 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 ability to successfully finance and complete our pending acquisitions and related development projects and, if completed, the ability of such newly acquired and new development properties to perform as we expect;

• our inability to renew tenant leases or obtain new tenant leases 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; and

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

The forward-looking statements should be read in light of these factors and the factors identified in the “Risk Factors” sections of our Annual Report on Form 10-K for the year ended December 31, 2016, as previously filed with the Securities and Exchange Commission (“SEC”) and of this Report below.

Overview

We are a fully-integrated real estate company that primarily owns, manages, and redevelops high quality retail properties, which we refer to as Community Centered Properties™. Our properties are located in attractive and affluent neighborhoods within high growth markets located primarily in the Sunbelt, such as Austin, Dallas-Fort Worth, Houston, Phoenix and San Antonio. We believe that gaining critical mass within these target markets, combined with our local market intelligence, existing platform, access to capital and broad network of industry relationships, gives us a competitive advantage and allows us to generate long-term return opportunities and added value for our shareholders.

23

In October 2006, our current management team joined the Company and adopted a strategic plan to acquire, redevelop, own and operate Community Centered Properties^TM.  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, medical, educational and financial services, and entertainment.  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.  We employ and develop a diverse group of associates who understand the needs of our multicultural communities and tenants.

We serve as the general partner of Whitestone REIT Operating Partnership, L.P. (the “Operating Partnership”), 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 March 31, 2017, we owned or had a majority interest in 69 commercial properties consisting of:

Consolidated Operating Portfolio

• 47 wholly-owned properties that meet our Community Centered Properties™ strategy containing approximately 4.4 million square feet of gross leasable area (“GLA”) and having a total carrying amount (net of accumulated depreciation) of $695.7 million; and

• as a result of the Contribution (as defined below), a majority interest in 14 consolidated properties that do not meet our Community Centered Properties™ strategy containing approximately 1.5 million square feet of GLA and having a total carrying amount (net of accumulated depreciation) of $60.3 million; and

Redevelopment, New Acquisitions Portfolio

• four retail properties that meet our Community Centered Properties™ strategy containing approximately 0.2 million square feet of GLA and having a total carrying value (net of accumulated depreciation) of $50.7 million; and

• four parcels of land held for future development having a total carrying value of $5.2 million.

As of March 31, 2017, we had an aggregate of 1,555 tenants.  We have a diversified tenant base with our largest tenant comprising only 3.0% of our annualized rental revenues for the three months ended March 31, 2017.  Lease terms for our properties range from less than one year for smaller tenants to over 15 years for larger tenants.  Our leases generally include minimum monthly lease payments and tenant reimbursements for payment of taxes, insurance and maintenance.  We completed 91 new and renewal leases during the three months ended March 31, 2017, totaling 220,293 square feet and approximately $16.3 million in total lease value.  This compares to 122 new and renewal leases totaling 285,202 square feet and approximately $16.1 million in total lease value during the same period in 2016.

We employed 103 full-time employees as of March 31, 2017.  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.

Pending Acquisitions

On April 19, 2017, we announced the pending acquisitions of two retail centers located at BLVD Place in Houston, Texas and Eldorado Plaza in McKinney, Texas, respectively, each of which is a property that meets our Community Centered Property™ strategy, for an aggregate purchase price of $204.6 million in cash. On May 3, 2017, we acquired Eldorado Plaza. Pursuant to the purchase agreement governing the acquisition of BLVD Place, we expect the closing of BLVD Place to occur in May 2017. BLVD Place contains 216,944 square feet of leasable space and is approximately 99% leased. In addition, included in the purchase of BLVD Place is approximately 1.43 acres of developable land that will give the Company the ability to build an estimated 136,930 square feet of additional leasable space, based on current plans. Eldorado Plaza contains 221,577 square feet of leasable space and is approximately 97% leased. Included in the purchase price of Eldorado Plaza is an option to purchase approximately 1.86 acres of developable land that will give us the ability to build an estimated 24,000 square feet of additional leasable space, based on current plans.

24

The closing of the acquisition of BLVD Place is not subject to a financing condition. We funded the purchase price of the acquisition of Eldorado Plaza and related transaction expenses through borrowings under our Facility. We expect to fund the purchase price of BLVD Place and related transaction expenses with a combination of net proceeds from the April Offering (as defined below) and $80 million of asset level mortgage financing (the “BLVD Financing”). We are currently negotiating the terms of the BLVD Financing with potential lenders, however we have not yet entered into a binding commitment letter or definitive loan documents and there can be no assurance that we will obtain the BLVD Financing on the terms we anticipate or at all. The consummation of the BLVD Place acquisition is not contingent on obtaining the BLVD Financing and, in the event we do not obtain the BLVD Financing, we expect to fund the purchase price of the BLVD Place acquisition through a combination of net proceeds from the April Offering, as discussed below, and borrowings under our Facility (as defined below). In addition, pursuant to the purchase agreements governing the acquisition of BLVD Place, the closing of BLVD Place is subject to the satisfaction or waiver of certain customary closing conditions. There can be no assurance that the closing of the acquisition of BLVD Place will occur in accordance with the anticipated timeline or at all. See “Risk Factors- There can be no assurance that the acquisition of BLVD Place will be consummated or that the BLVD Financing will be obtained in accordance with the anticipated timing or at all.”

April Offering

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 purchase price of $12.48 per share (the “April Offering”). Total net proceeds from the April 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 intends to use the net proceeds from the April Offering initially to repay a portion of outstanding indebtedness under the Facility, which amounts will then become available for future borrowings, including the funding of a portion of the purchase price of the acquisitions of Eldorado Plaza and BLVD Place or for general corporate purposes.

Eldorado Plaza Acquisition

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 from borrowings under our Facility. 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.

How We Derive Our Revenue

Substantially all of our revenue is derived from rents received from leases at our properties. We had rental income and tenant reimbursements of approximately $28.3 million and $25.4 million for the three months ended March 31, 2017 and 2016, respectively.

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 two 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 2017.

25

Scheduled Lease Expirations

We tend to lease space to smaller businesses that desire shorter term leases. As of March 31, 2017, approximately 28% of our GLA was subject to leases that expire prior to December 31, 2018.  Over the last two years, we have renewed leases covering approximately 77% of the square footage subject to expiring 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 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, Dispositions and Development

We seek to acquire commercial properties in high-growth markets. Our acquisition targets are properties that fit our Community Centered Properties^TM strategy.  We define Community Centered Properties^TM as visibly located properties in established or developing, culturally diverse neighborhoods in our target markets, primarily in and around Austin, Dallas-Fort Worth, Houston, Phoenix and San Antonio.  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, medical, educational and financial services and entertainment.  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.

On December 8, 2016, we, through our Operating Partnership, entered into a Contribution Agreement (the “Contribution Agreement”) with Pillarstone Capital REIT Operating Partnership LP (“Pillarstone," "Pillarstone OP" or the "Consolidated Partnership") 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 for aggregate consideration of approximately $84 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 2014 Facility (See Note 7 (Debt) 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 March 31, 2017, we owned approximately 81.4% of the total outstanding Pillarstone OP Units. Accordingly, we account for Pillarstone OP as a VIE and fully consolidate in our consolidated balance sheets and related consolidated statement of operations and comprehensive income.

Property acquisitions. On September 30, 2016, we acquired La Mirada and Seville, properties that meet our Community Centered Property™ strategy, for 621,053 OP units and $60.7 million in cash and net prorations. The OP units are redeemable for cash or, at our option, Whitestone REIT common shares on a one-for-one basis, subject to certain restrictions. La Mirada, a 147,209 square foot property, was 90% leased at the time of purchase. Seville, a 90,042 square foot property, was 88% leased at the time of purchase. Both properties are located in Scottsdale, Arizona.

Development properties. As of March 31, 2017, we had substantially completed construction at our Pinnacle of Scottsdale Phase II property. As of March 31, 2017, we had incurred approximately $4.5 million in construction costs, including approximately $0.5 million in previously capitalized interest and real estate taxes. The 27,063 square foot Community Centered Property was 44% leased as of March 31, 2017 and is located in Scottsdale, Arizona, and adjacent to Pinnacle of Scottsdale.

On December 31, 2016, we had substantially completed construction at our Shops at Starwood Phase III property. As of March 31, 2017, we had incurred approximately $7.6 million in construction costs, including approximately $0.8 million in previously capitalized interest and real estate taxes. The 35,351 square foot Community Centered Property was 50% leased as of March 31, 2017 and is located in Frisco, Texas, a northern suburb of Dallas, Texas, and adjacent to Shops at Starwood.

Property revenues. We had rental income and tenant reimbursements of approximately $28,267,000 for the three months ended March 31, 2017 as compared to $25,435,000 for the three months ended March 31, 2016, an increase of $2,832,000, or 11%. The three months ended March 31, 2017 included $1,790,000 in increased revenues from Non-Same Store operations and $23,000 in increased revenues from our Consolidated Partnership. 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. Same Store revenues increased $1,019,000 for the three months ended March 31, 2017 as compared to the same period in the prior year. We define “Same Stores” as properties that have been owned for the entire period being compared. For purposes of comparing the three months ended March 31, 2017 to the three months ended March 31, 2016, Same Stores include properties owned during the entire period from January 1, 2016 to March 31, 2017. Same Store revenue increased $204,000 for the three months ended March 31, 2017 as compared to the three months ended March 31, 2016 as the result of an increase in the average leased square feet to 3,834,000 from 3,798,000. The Same Store average revenue per leased square foot increased $0.85 for the three months ended March 31, 2017 to $23.40 per leased square foot as compared to the average revenue per leased square foot of $22.55 for the three months ended March 31, 2016, resulting in an increase of Same Store revenues of $815,000.

Property expenses.  Our property expenses were approximately $9,414,000 for the three months ended March 31, 2017 as compared to $8,148,000 for the three months ended March 31, 2016, an increase of $1,266,000, or 16%.  The primary components of property expenses are detailed in the table below (in thousands, except percentages):

Real estate taxes.  Real estate taxes increased approximately $566,000, or 17%, during the three months ended March 31, 2017 as compared to the same period in 2016. The real estate tax increase was comprised of increases of $358,000, $125,000 and $83,000 in our Same Store, Consolidated Partnership and Non-Same Store properties, respectively. The increase in Same Store real estate tax expense was primarily attributable to increased assessments with tax authorities in our Texas markets resulting in larger expenses paid for 2016 taxes. Many of the tax assessments on our properties are still under protest for 2016, and we expect to achieve further reductions through the litigation process. 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 expenses increased approximately $140,000, or 13%, during the three months ended March 31, 2017 as compared to the same period in 2016. The utility expense increase was comprised of $53,000, $47,000 and $40,000 in our Non-Same Store, Consolidated Partnership and Same Store properties, respectively. The majority of the Same Store increase was from increased electricity costs in our Houston market.

Contract services.  Contract services expenses increased approximately $212,000, or 15%, during the three months ended March 31, 2017 as compared to the same period in 2016. The contract services increase was comprised of $102,000, $60,000 and $50,000 in our Non-Same Store, Consolidated Partnership and Same Store properties, respectively.

Repairs and maintenance. Repairs and maintenance expenses increased approximately $171,000, or 18%, during the three months ended March 31, 2017 as compared to the same period in 2016. The repairs and maintenance increase was comprised of increases of $126,000 in Same Store properties and $51,000 in our Non-Same Store properties, offset by a decrease of $6,000 in our Consolidated Partnership properties. The Same Store properties increase was primarily comprised of recoverable painting, landscaping and roofing costs.

Bad debt.  Bad debt expenses increased approximately $235,000, or 63%, during the three months ended March 31, 2017 as compared to the same period in 2016. The bad debt expense increase was comprised of $180,000, $36,000 and $19,000 in our Same Store, Non-Same Store and Consolidated Partnership properties, respectively. The $180,000 increase in Same Store bad debt was primarily from a large tenant that vacated their space in our Arizona region.

Labor and other.  Labor and other expenses decreased approximately $58,000, or 6%, during the three months ended March 31, 2017 as compared to the same period in 2016.

Other expenses.  Our other expenses were approximately $17,192,000 for the three months ended March 31, 2017, as compared to $14,935,000 for the three months ended March 31, 2016, an increase of $2,257,000, or 15%.  The primary components of other expenses are detailed in the table below (in thousands, except percentages):

	Three Months Ended

Total other expenses	$	17,192		$	14,935		$	2,257		15	%

General and administrative. General and administrative expenses increased approximately $1,333,000, or 28%, for the three months ended March 31, 2017 as compared to the same period in 2016. The increase was comprised of $426,000 in increased share-based compensation expense, $220,000 in increased salaries and benefits, $188,000 in increased legal fees, $184,000 in increased other professional fees, $119,000 in increased accounting fees and $196,000 in increased other expenses.

Total compensation recognized in earnings for share-based payments was $2,451,000 and $2,025,000 for the three months ended March 31, 2017 and 2016, respectively.

Based on our current financial projections, we expect approximately 82%of the unvested awards to vest over the next24months. As ofMarch 31, 2017, there was approximately $3.2 million in unrecognized compensation cost related to outstanding non-vested performance-based shares, which are expected to vest over a period of 24 months and approximately $5.4 million in unrecognized compensation cost related to outstanding non-vested time-based shares, which are expected to be recognized over a period of approximately 12 months beginning on April 1, 2017.

We expect to record approximately $8.6 millionin non-cash share-based compensation expense in 2017 and$2.5 millionsubsequent to 2017. The unrecognized share-based compensation cost is expected to vest over a weighted average period of16months.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.

Depreciation and amortization. Depreciation and amortization increased $616,000, or 11%, for the three months ended March 31, 2017 as compared to the same period in 2016. Depreciation for improvements to Same Store properties increased $261,000 for the three months ended March 31, 2017 as compared to the same period in 2016. Depreciation for Non-Same Store properties increased $270,000 and depreciation for Consolidated Partnership properties increased $74,000. Lease commission amortization and depreciation of corporate assets increased $11,000 for the three months ended March 31, 2017 as compared to the same period in 2016.

Interest expense. Interest expense increased approximately $349,000, or 7%, for the three months ended March 31, 2017 as compared to the same period in 2016. The increase in interest expense is comprised of approximately $426,000 in increased interest expense resulting from a $47,766,000 increase in our average notes payable balance offset by a $72,000 decrease in interest expense resulting from a decrease in the average effective interest rate on our average notes payable from 3.57% to 3.51% and a decrease in amortized loan fees included in interest expense of $5,000.

Interest, dividend and other investment income. Interest, dividend and other investment income increased approximately $41,000, or 42%, for the three months ended March 31, 2017 as compared to the same period in 2016. The increase in interest, dividend and other investment income for the three months ended March 31, 2017 as compared to the same period in 2016 is comprised of approximately $42,000 in increased interest income and was offset by a $1,000 decrease in dividend income.

Reconciliation of Non-GAAP Financial Measures

Funds From Operations (“FFO”)

The National Association of Real Estate Investment Trusts (“NAREIT”) defines FFO as net income (loss) available to common shareholders computed in accordance with U.S. GAAP, excluding gains or losses from sales of operating real estate assets, impairment charges on properties held for investment and extraordinary items, plus depreciation and amortization of operating properties, including our share of unconsolidated real estate joint ventures and partnerships.  We calculate FFO in a manner consistent with the NAREIT definition.

Management uses FFO as a supplemental measure to conduct and evaluate our business because there are certain limitations associated with using U.S. GAAP net income (loss) alone as the primary measure of our operating performance. Historical cost accounting for real estate assets in accordance with U.S. 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 U.S. 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, non-cash share-based compensation expense, rent support agreement payments received from sellers on acquired assets 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.

Below are the calculations of FFO and FFO Core and the reconciliations to net income, which we believe is the most comparable U.S. GAAP financial measure (in thousands):

Property Net Operating Income (“NOI”)

Management believes that NOI is a useful measure of our property operating performance and is useful to securities analysts in estimating the relative net asset values of REITs. 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 and gain or loss on sale or disposition of assets, 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 reconciliations to net income, which we believe is the most comparable U.S. GAAP financial measure (in thousands):

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 three months ended March 31, 2017, our cash provided from operating activities was $883,000 and our total distributions were $8,766,000.  Therefore, we had distributions in excess of cash flow from operations of approximately $7,883,000. We anticipate that cash flows from operating activities and our borrowing capacity under our unsecured revolving credit facility will provide adequate capital for our 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.

37

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 properties 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 continue acquiring such additional properties that meet our Community Centered Property™ strategy through equity issuances and debt financing. For example, on April 19, 2017, we announced the acquisitions of Eldorado Plaza and BLVD Place and, on April 25, 2017, we completed the April Offering. On May 3, 2017, we acquired Eldorado Plaza. We funded the purchase price of Eldorado Plaza and related transaction expenses with borrowings under our Facility. We expect to fund the purchase price of the acquisition of BLVD Place and related transaction expenses through a combination of net proceeds from the April Offering and the BLVD Financing. We expect to obtain the BLVD Financing and close the acquisition of BLVD Place in May 2017. Included in the purchase of Eldorado Plaza is approximately 1.86 acres of developable land that will give us the ability to build an estimated 24,000 square feet of additional leasable space for an estimated cost to acquire and develop the land parcel of approximately $4.0 million, based on current plans. Further, included in the purchase of BLVD Place is an option to purchase approximately 1.43 acres of developable land. We currently intend to develop a six-story, 137,000 square foot mixed-use building, which we refer to as the BLVD Phase II-B development, on the developable land at BLVD Place, for an estimated cost to acquire and develop the land parcel of $55.0 million, including the $10.0 million of the aggregate purchase price of BLVD Place allocated to the acquisition of the land parcel. Construction of the BLVD Phase II-B development is expected to begin shortly after the closing of the BLVD Place acquisition and is expected to take approximately 18 months to complete.

As discussed in Note 11 (Equity) to the accompanying consolidated financial statements, on June 4, 2015, we entered into the 2015 equity distribution agreements.  Pursuant to the terms and conditions of the 2015 equity distribution agreements, we can issue and sell up to an aggregate of $50 million of our common shares into the existing trading market at current market prices or at negotiated prices through the placement agents over a period of time and from time to time. During the three months ended March 31, 2017, we sold 390,726 common shares under the 2015 equity distribution agreements, with net proceeds to us of approximately $5.3 million. In connection with such sales, we paid compensation of approximately $0.1 million to the sales agents. We had not sold any common shares under the 2015 equity distribution agreements as of March 31, 2016. We have used and anticipate using net proceeds from common shares issued pursuant to the 2015 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.

Our capital structure includes non-recourse mortgage debt that we have assumed or originated on certain properties. We may hedge the future cash flows of certain variable rate debt transactions principally through interest rate swaps with major financial institutions. See Note 8 (Derivatives and Hedging Activities) to the accompanying consolidated financial statements for a description of our current cash flow hedges.

As discussed in Note 2 (Summary of Significant Accounting Policies) to the accompanying consolidated financial statements, pursuant to the terms of our $15.1 million4.99% Note, due January 6, 2024 (see Note 7 (Debt) 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 $6,503,000 as of March 31, 2017, as compared to $4,168,000 on December 31, 2016.  The increase of $2,335,000 was primarily the result of the following:

Sources of Cash

• Cash flow from operations of $883,000 for the three months ended March 31, 2017;

38

• Proceeds of $11,000,000 from the Facility;

• Net proceeds of $5,334,000 from issuance of common shares;

Uses of Cash

• Payment of distributions to common shareholders and OP unit holders of $8,766,000;

• Additions to real estate of $4,556,000;

• Change in restricted cash of $100,000;

• Repurchase of common shares of $591,000; and

• Payments of notes payable of $869,000.

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

As part of our acquisition of Paradise Plaza in August 2012, we recorded a discount on the note of $1.3 million, which amortizes into interest expense over the life of the loan and results in an imputed interest rate of 4.13%.

⁽⁷⁾  Unsecured line of credit includes certain Pillarstone Properties.

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, 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 “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 “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 “Term Loans”) to January 29, 2021 from November 7, 2019.

Borrowings under the 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. The applicable margin for Adjusted LIBOR borrowings ranges from 1.40% to 1.95% for the Revolver and 1.35% to 2.25% for the 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.

We serve as the guarantor for funds borrowed by the Operating Partnership under the Facility. The 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 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.

The Facility includes an accordion feature that will allow the Operating Partnership to increase the borrowing capacity to $700 million, upon the satisfaction of certain conditions. As of March 31, 2017, $397.6 million was drawn on the Facility, and our remaining borrowing capacity was $102.4 million. Proceeds from the Facility were used for general corporate purposes, including property acquisitions, debt repayment, capital expenditures, the expansion, redevelopment and retenanting of properties in our portfolio and working capital. We intend to use the additional proceeds from the Facility for general corporate purposes, including property acquisitions, debt repayment, capital expenditure, the expansion, redevelopment and re-tenanting of properties in our portfolio and working capital.

40

On December 8, 2016, in connection with the Contribution, the Operating Partnership entered into the Second Amendment to the Facility and Reaffirmation of Guaranties (the “Second Amendment”) with Pillarstone, 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 Facility) and Guarantors under the Facility and their respective Pillarstone Properties were each permitted to remain an Eligible Property (as defined in the Facility) and be included in the Borrowing Base (as defined in the Facility) under the Facility. In addition, on December 8, 2016, Pillarstone entered into the Limited Guarantee (the “Limited Guarantee”) with the Agent, pursuant to which Pillarstone agreed to be joined as a party to the 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 March 31, 2017, Pillarstone accounted for approximately $15.5 million of the total amount drawn on the Facility.

As of March 31, 2017, our $158.4 million in secured debt was collateralized by 19 properties with a carrying value of $189.0 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.  As of March 31, 2017, we were in compliance with all loan covenants.

Scheduled maturities of our outstanding debt as of March 31, 2017 were as follows (in thousands):

Year	Amount Due
2017	$	10,562
2018	12,136
2019	205,649
2020	82,827
2021	51,918
Thereafter	193,727
Total	$	556,819

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 that 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 the markets on which we focus 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.

Contractual Obligations

During the three months ended March 31, 2017, there were no material changes outside of the ordinary course of business to the information regarding specified contractual obligations contained in our Annual Report on Form 10-K for the year ended December 31, 2016.

41

Distributions

The following table summarizes the cash distributions paid or payable to holders of our common shares and noncontrolling OP units during each quarter during 2016 and the three months ended March 31, 2017 (in thousands, except per share data):

Total	$	1.1400	$	31,911	$	1.1400	$	729	$	32,640

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.

Income earned by our taxable REIT subsidiary, Whitestone Davenport TRS LLC (“Davenport TRS”), is subject to federal income tax. For the three months ended 2016, we recognized $45,000 in income tax expense related to Davenport TRS taxable year. Davenport TRS was dissolved in the fourth quarter of 2016.

Environmental Matters

Our properties are subject to environmental laws and regulations adopted by various governmental authorities in the jurisdictions in which our operations are conducted. From our inception, we have incurred no significant environmental costs, accrued liabilities or expenditures to mitigate or eliminate future environmental contamination.

Off-Balance Sheet Arrangements

We had no significant off-balance sheet arrangements as of March 31, 2017 and December 31, 2016.

Item 3.  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 March 31, 2017, $359.2 million, or approximately 65% 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 of our fixed interest rate debt, it does not impact net income to shareholders or cash flows. Our total outstanding fixed interest rate debt had an average effective interest rate as of March 31, 2017 of approximately 3.84% per annum with scheduled maturities ranging from 2017 to 2024 (see Note 7 (Debt) to the accompanying consolidated financial statements for further detail). Holding other variables constant, a 1% increase or decrease in interest rates would cause a $13.7 million decline or increase, respectively, in the fair value for our fixed rate debt.

Variable Interest Rate Debt

As of March 31, 2017, $197.6 million, or approximately 35% of our outstanding debt, was subject to floating interest rates of LIBOR plus 1.40% to 1.95% and not currently subject to a hedge. The impact of a 1% increase or decrease in interest rates on our non-hedged variable rate debt would result in a decrease or increase of annual net income of approximately $2.0 million, respectively.

42

Item 4.  Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

The management of Whitestone REIT, under the supervision and with the participation of our principal executive and financial officers, has evaluated the effectiveness of our disclosure controls and procedures in ensuring that the information required to be disclosed in our filings under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, including ensuring that such information is accumulated and communicated to Whitestone REIT's management, as appropriate, to allow timely decisions regarding required disclosure. Based on such evaluation, our principal executive and financial officers have concluded that such disclosure controls and procedures were effective as of March 31, 2017 (the end of the period covered by this Report).

Changes in Internal Control Over Financial Reporting

During the three months ended March 31, 2017, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

43

PART II. OTHER INFORMATION

Item 1. Legal Proceedings.

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 or liquidity.

Item 1A. Risk Factors.

Other than the addition of the risk factors below, there have been no material changes from the risk factors disclosed in the “Risk Factors” section of Whitestone’s Annual Report on Form 10-K for the year ended December 31, 2016.

There can be no assurance that the acquisition of BLVD Place will be consummated or that the BLVD Financing will be obtained in accordance with the anticipated timing or at all.

Although we expect to obtain the BLVD Financing and close the acquisition of BLVD Place in May 2017, there can be no assurance that the BLVD Financing will obtained or that the acquisition of BLVD Place will be completed in accordance with the anticipated timing or at all or on the terms or in the manner currently anticipated. We currently expect to fund the purchase price of the acquisition of BLVD Place and related transaction expenses through a combination of net proceeds from the April Offering and the BLVD Financing. However, we have not yet entered into a binding commitment letter or definitive loan documents with respect to the BLVD Financing and there can be no assurance that we will obtain the BLVD Financing on the terms we anticipate or at all. The consummation of the BLVD Place acquisition is not contingent on obtaining the BLVD Financing and, in the event we do not obtain the BLVD Financing, we expect to fund the purchase price of the BLVD Place acquisition through a combination of net proceeds from the April Offering and borrowings under our Facility.

In addition, the acquisition of BLVD Place is subject to customary closing conditions which may not be satisfied or waived, in which case we will not be obligated to complete the acquisition of BLVD Place and, in certain circumstances, the sellers may retain our earnest money deposits on the acquisition of BLVD Place. Further, under certain circumstances specified in the purchase agreements governing the acquisition of BLVD Place, we may terminate such purchase agreements.

The price of our common shares may decline to the extent that the current market price of our common shares reflects a market assumption that the acquisition of BLVD Place will be consummated and that we will realize certain anticipated benefits of the acquisition of BLVD Place.

The acquisitions of Eldorado Plaza and BLVD Place may not achieve their intended benefits.

There can be no assurance that we will be able to successfully realize the expected benefits of the acquisitions of Eldorado Plaza and BLVD Place. Our ability to realize the anticipated benefits of the acquisitions of Eldorado Plaza and BLVD Place will depend, in part, on our ability to integrate Eldorado Plaza and BLVD Place with our existing business. Integrating Eldorado Plaza and BLVD Place and leveraging our existing property management platform to service these new properties and tenants will require significant time and focus from our management team and may divert attention from the day-to-day operations of the combined business, which could delay the achievement of our broader strategic objectives. In addition, the integration of these new properties into our existing business may result in material unanticipated problems, expenses and liabilities as a result of a number of factors, including:

• market conditions in the submarkets in which Eldorado Plaza and BLVD Place are located may result in higher than expected vacancy rates and lower than expected rental rates;

• Eldorado Plaza and BLVD Place may be subject to reassessment, which may result in higher than expected tax payments;

• we may have underestimated the costs to make any necessary improvements to Eldorado Plaza and BLVD Place; and

• we may encounter unanticipated problems, expenses and liabilities in connection with the development of the land parcels included in Eldorado Plaza and BLVD Place and, as a result, may be unable to realize the rental revenues expected to be received from the developable GLA on the timelines or at the rates we anticipate, if at all.

44

Many of these risks will be outside of our control and any one of them could result in increased costs, decreases in the amount of expected revenue, lower than projected unlevered internal rates of return and diversion of our management team’s time and energy, which could adversely affect our business, financial condition, results of operations and/or cash flows.

We will increase our concentration of properties in the Houston and Dallas metropolitan areas as a result of the acquisitions of Eldorado Plaza and BLVD Place, which could have an adverse effect on our operations if the Houston or Dallas market is adversely affected by economic or other conditions.

As a result of the acquisition of Eldorado Plaza and BLVD Place, we will increase our concentration of properties in the Houston and Dallas areas. A majority of our assets and revenues are currently derived from properties located in the Houston and Phoenix metropolitan areas. As of December 31, 2016, on a pro forma basis giving effect to the acquisition of Eldorado Plaza and BLVD Place, approximately 29% of our wholly-owned GLA and 29% of our retail NOI would have been located in Houston, approximately 46% of our wholly-owned GLA and 42% of our retail NOI would have been located in Phoenix and approximately 11% of our wholly-owned GLA and 13% of our retail NOI would have been located in Dallas. Our results of operations are directly affected by our ability to attract financially sound commercial tenants. A significant economic downturn in Houston, including as a result of the recent or future significant decline in oil prices, Dallas or the 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 the Houston, Dallas or Phoenix metropolitan area experiences 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 and Dallas 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 and Dallas tenants.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

(a) During the period covered by this Form 10-Q, we did not sell any equity securities that were not registered under the Securities Act of 1933, as amended.

(b) Not applicable.

(c) Issuer Purchases of Equity Securities

During the three months ended March 31, 2017, certain of our employees tendered owned common shares to satisfy the tax withholding on the lapse of certain restrictions on restricted common shares issued under the 2008 Plan. The following table summarizes all of these repurchases during the three months ended March 31, 2017.

Period	Total Number of Shares Purchased (1)	Average Price Paid for Shares		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs	Maximum Number of Shares that May Yet be Purchased Under the Plans or Programs
January 1, 2017 through January 31, 2017	—	$	—	N/A	N/A
February 1, 2017 through February 28, 2017	—	—		N/A	N/A
March 1, 2017 through March 31, 2017	42,534	13.84		N/A	N/A
Total	42,534	$	13.84

⁽¹⁾    The number of shares purchased represents common shares held by employees who tendered owned common shares to satisfy the tax withholding on the lapse of certain restrictions on restricted common shares issued under the 2008 Plan. With respect to these shares, the price paid per share is based on the fair market value at the time of tender.

Interim Financial Statements

INTERIM FINANCIAL STATEMENTS

The consolidated financial statements included in this report are unaudited; however, amounts presented in the consolidated balance sheet as of December 31, 2016 are derived from our audited consolidated financial statements as of that date.  The unaudited financial statements as of and for the period ended March 31, 2017 have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information on a basis consistent with the annual audited consolidated financial statements and with the instructions to Form 10-Q.

The consolidated financial statements presented herein reflect all adjustments which, in the opinion of management, are necessary for a fair presentation of the financial position of Whitestone and our subsidiaries as of March 31, 2017, and the results of operations for the three month periods ended March 31, 2017 and 2016, the consolidated statements of changes in equity for the three month period ended March 31, 2017 and cash flows for the three month periods ended March 31, 2017 and 2016.  All of these adjustments are of a normal recurring nature.  The results of operations for the interim periods are not necessarily indicative of the results expected for a full year.  The statements should be read in conjunction with the audited consolidated financial statements and the notes thereto which are included in our Annual Report on Form 10-K for the year ended December 31, 2016.

Business.  Whitestone was formed as a real estate investment trust (“REIT”) 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 REIT formed for the sole purpose of the reorganization and the conversion of each of the 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”), 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 March 31, 2017 and December 31, 2016, Whitestone owned or held a majority interest in 69 commercial properties in and around Austin, Chicago, Dallas-Fort Worth, Houston, Phoenix and San Antonio.

Summary of Significant Accounting Policies

Accounting Policies [Abstract]

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 March 31, 2017 and December 31, 2016, 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. We also consolidate a variable interest entity (“VIE”) when we are determined to be the primary beneficiary. Determination of the primary beneficiary is based on whether an entity has (1) the power to direct activities that most significantly impact the economic performance of the VIE and (2) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Our determination of the primary beneficiary considers all relationships between us and the VIE, including management and other contractual agreements. See Note 6 for additional disclosure on our VIE.

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 period. 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.

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. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities as of 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 period amounts in the accompanying consolidated financial statements in order to be consistent with the current period presentation. 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 (See Note 7), 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. As a result, these amounts are reported in the consolidated statements of cash flows under cash flows from financing activities as change in restricted cash.

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.

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 (loss) and subsequently reclassified into earnings in the period that the hedged transaction affects earnings. Any ineffective portion of a cash flow hedges' 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 March 31, 2017, we consider our cash flow hedges to be highly effective.

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 three months ended March 31, 2017, approximately $72,000 and $29,000 in interest expense and real estate taxes, respectively, were capitalized, and for the three months ended March 31, 2016, approximately $27,000 and $16,000 in interest expense and real estate taxes, respectively, were capitalized.

Real Estate Held for Sale and Discontinued Operations. We consider a commercial property to be held for sale when it meets all of the criteria established under ASC 205, “Presentation of Financial Statements.” For commercial properties classified as held for sale, assets and liabilities are presented separately for all periods presented.

In accordance with ASC 205,a discontinued operation may include a component of an entity or a group of components of an entity. A disposal of a component of an entity or a group of components of an entity is reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results when the component of an entity or group of components of an entity is classified as held for sale, disposed of by sale or disposed of other than by sale, respectively. In addition, ASC 205 requires us to provide additional disclosures about both discontinued operations and the disposal of an individually significant component of an entity that does not meet the criteria for a discontinued operation.

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 2008 Long-Term Equity Incentive Ownership Plan (the “2008 Plan”).  The vast majority of the 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 $2,451,000 and $2,025,000 in share-based compensation for the three months ended March 31, 2017 and 2016, respectively.

Noncontrolling Interests.  Noncontrolling interests is 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, subsidiaries are reported at the consolidated amount, including both the amount attributable to Whitestone and noncontrolling interests.  The consolidated statement of changes in equity is included for quarterly financial statements, including beginning balances, activity for the period and ending balances for shareholders' equity, noncontrolling interests and total equity.

See our Annual Report on Form 10-K for the year ended December 31, 2016 for further discussion on significant accounting policies.

Recent Accounting Pronouncements.  In February 2016, the FASB issued guidance requiring lessees to recognize a lease liability and a right-of-use asset for all leases. Lessor accounting will remain largely unchanged with the exception of changes related to costs which qualify as initial direct costs. The guidance will also require new qualitative and quantitative disclosures to help financial statement users better understand the timing, amount and uncertainty of cash flows arising from leases. This guidance will be effective for reporting periods beginning on or after December 15, 2018, with early adoption permitted. We are currently evaluating the impact of this guidance and its impact on our consolidated financial statements.

In March 2016, the FASB issued guidance simplifying the accounting for share-based payment transactions, including the income tax consequences, balance sheet classification of awards and the classification on the statement of cash flows. We have adopted this guidance as of January 1, 2017. The main provision regarding excess tax benefits did not have an impact on our consolidated financial statements due to our status as a REIT for taxation purposes. We have elected to continue estimating the number of shares expected to vest in order to determine compensation cost, and we will continue to classify cash paid by us for employee taxes when common shares were repurchased to cover minimum statutory requirements as financing activity.

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 will become effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We are currently evaluating the impact of this guidance and its impact on our consolidated financial statements.

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 disposals) of assets or businesses. This guidance will become effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We are currently evaluating the impact of this guidance and its impact on our consolidated financial statements.

In February 2017, the FASB issued guidance clarifying the scope of asset derecognition guidance, adds guidance for partial sales of nonfinancial assets and clarifies recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. This guidance will become effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We are currently evaluating the impact of this guidance and its impact on our consolidated financial statements.

VARIABLE INTEREST ENTITIES

On December 8, 2016, we, through our Operating Partnership, entered into a Contribution Agreement (the “Contribution Agreement”) with Pillarstone Capital REIT Operating Partnership LP (“Pillarstone,” “Pillarstone OP” or the “Consolidated Partnership”) 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 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 2014 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, on December 8, 2016, the Operating Partnership entered into an OP Unit Purchase Agreement (the “OP Unit Purchase Agreement”) with Pillarstone REIT and Pillarstone OP 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 OP 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 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.

As of March 31, 2017, 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. We have determined that we are the primary beneficiary of Pillarstone OP, through our power to direct the activities of Pillarstone OP, additional working capital required by Pillarstone OP under the OP Unit Purchase Agreement and our obligation to absorb losses and receive benefits based on our ownership percentage. Accordingly, we account for Pillarstone OP as a VIE and fully consolidate in our consolidated financial statements.

• 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 “Term Loans”) to January 29, 2021 from November 7, 2019.

Borrowings under the 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. The applicable margin for Adjusted LIBOR borrowings ranges from 1.40% to 1.95% for the Revolver and 1.35% to 2.25% for the 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.

We serve as the guarantor for funds borrowed by the Operating Partnership under the Facility. The 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 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.

The Facility includes an accordion feature that will allow the Operating Partnership to increase the borrowing capacity to $700 million, upon the satisfaction of certain conditions. As of March 31, 2017, $397.6 million was drawn on the Facility, and our remaining borrowing capacity was $102.4 million. Proceeds from the Facility were used for general corporate purposes, including property acquisitions, debt repayment, capital expenditures, the expansion, redevelopment and retenanting of properties in our portfolio and working capital. We intend to use the additional proceeds from the Facility for general corporate purposes, including property acquisitions, debt repayment, capital expenditure, the expansion, redevelopment and re-tenanting of properties in our portfolio and working capital.

On December 8, 2016, in connection with the Contribution, the Operating Partnership entered into the Second Amendment to the Facility and Reaffirmation of Guaranties (the “Second Amendment”) with Pillarstone, 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 Facility) and Guarantors under the Facility and their respective Pillarstone Properties were each permitted to remain an Eligible Property (as defined in the Facility) and be included in the Borrowing Base (as defined in the Facility) under the Facility. In addition, on December 8, 2016, Pillarstone entered into the Limited Guarantee (the “Limited Guarantee”) with the Agent, pursuant to which Pillarstone agreed to be joined as a party to the 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 March 31, 2017, Pillarstone accounted for approximately $15.5 million of the total amount drawn on the Facility.

As of March 31, 2017, our $158.4 million in secured debt was collateralized by 19 properties with a carrying value of $189.0 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.  As of March 31, 2017, we were in compliance with all loan covenants.

Scheduled maturities of our outstanding debt as of March 31, 2017 were as follows (in thousands):

Earnings (Loss) 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 common shares and the net income attributable to noncontrolling 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 common shares and the net income attributable to noncontrolling interests by the weighted average number of common shares including any dilutive unvested restricted common shares.

Certain of our performance-based restricted common shares are considered participating securities that require the use of the two-class method for the computation of basic and diluted earnings per share.  During the three months ended March 31, 2017 and 2016, 1,099,827 and 491,023 OP units, respectively, were excluded from the calculation of diluted earnings per share because their effect would be anti-dilutive.

For the three months ended March 31, 2017 and 2016, distributions of $95,000 and $155,000, respectively, were made to holders of certain restricted common shares, $4,000 and $0, respectively, of which were charged against earnings. See Note 12 for information related to restricted common shares under the 2008 Plan.

Income Taxes

INCOME TAXES

With the exception of our taxable REIT subsidiaries, federal income taxes are generally not provided because we intend to and believe we qualify as a REIT under the provisions of the Internal Revenue Code (the “Code”) and because we have distributed and intend to continue to distribute all of our taxable income to our shareholders.  As a REIT, we must distribute at least 90% of our REIT 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 (including any applicable alternative minimum tax) on our taxable income at regular corporate tax rates.

Income earned by our taxable REIT subsidiary, Whitestone Davenport TRS LLC (“Davenport TRS”), is subject to federal income tax. For the three months ended March 31, 2016, we recognized $45,000 in income tax expense related to Davenport TRS taxable year. Davenport TRS was dissolved in the fourth quarter of 2016.

We are subject to the Texas Margin Tax, which is computed by applying the applicable tax rate (0.75% 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” applies to the Texas Margin Tax.  For the three months ended March 31, 2017 and 2016, we recognized approximately $79,000 and $114,000 in margin tax provision, respectively.

Common Shares

Under our declaration of trust, as amended, we have authority to 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.

Equity Offerings

On June 4, 2015, we entered into six amended and restated equity distribution agreements for an at-the-market equity distribution program (the “2015 equity distribution agreements”). Pursuant to the terms and conditions of the 2015 equity distribution agreements, we can issue and sell up to an aggregate of $50 million of our common shares. Actual sales will depend on a variety of factors to be 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 will be 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 2015 equity distribution agreements or terminate the 2015 equity distribution agreements. During the three months ended March 31, 2017, we sold 390,726 common shares under the 2015 equity distribution agreements, with net proceeds to us of approximately $5.3 million. In connection with such sales, we paid compensation of approximately $0.1 million to the sales agents. We did not sell any common shares under the 2015 equity distribution agreements during the three months ended March 31, 2016.

Operating Partnership Units

Substantially all of our business is conducted through our Operating Partnership.  We are the sole general partner of the Operating Partnership.  As of March 31, 2017, we owned a 96.4% 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 holders of Whitestone common shares.  As of March 31, 2017 and December 31, 2016, there were 30,845,917 and 30,450,377 OP units outstanding, respectively.  We owned 29,750,636 and 29,347,741 OP units as of March 31, 2017 and December 31, 2016, respectively. The balance of the OP units is owned by third parties, including certain members of our board of trustees.  Our weighted average share ownership in the Operating Partnership was approximately 96.4% and 98.2% for the three months ended March 31, 2017 and 2016, respectively. During the three months ended March 31, 2017 and 2016, 7,355 and 12,101 OP units, respectively, were redeemed for an equal number of common shares.

Employee 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 common shares and/or OP 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 51 of our employees. The modified time-based shares will vest 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. If the performance targets are not met prior to December 31, 2018, any unvested performance-based restricted common shares and restricted common share units will be forfeited.

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.

A summary of the share-based incentive plan activity as of and for the three months ended March 31, 2017 is as follows:

	Shares		Weighted Average Grant Date Fair Value

Total compensation recognized in earnings for share-based payments was $2,451,000 and $2,025,000 for the three months ended March 31, 2017 and 2016, respectively.

Based on our current financial projections, we expect approximately 82%of the unvested awards to vest over the next24months. As ofMarch 31, 2017, there was approximately $3.2 million in unrecognized compensation cost related to outstanding non-vested performance-based shares, which are expected to vest over a period of 24 months and approximately $5.4 million in unrecognized compensation cost related to outstanding non-vested time-based shares, which are expected to be recognized over a period of approximately 12 months beginning on April 1, 2017.

We expect to record approximately $8.6 millionin non-cash share-based compensation expense in 2017 and$2.5 millionsubsequent to 2017. The unrecognized share-based compensation cost is expected to vest over a weighted average period of16months.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.

Property acquisitions. On September 30, 2016, we acquired La Mirada and Seville, properties that meet our Community Centered Property™ strategy, for 621,053 OP units and $60.7 million in cash and net prorations. The OP units are redeemable for cash or, at our option, Whitestone REIT common shares on a one-for-one basis, subject to certain restrictions. La Mirada, a 147,209 square foot property, was 90% leased at the time of purchase. Seville, a 90,042 square foot property, was 88% leased at the time of purchase. Both properties are located in Scottsdale, Arizona.

Development properties. As of March 31, 2017, we had substantially completed construction at our Pinnacle of Scottsdale Phase II property. As of March 31, 2017, we had incurred approximately $4.5 million in construction costs, including approximately $0.5 million in previously capitalized interest and real estate taxes. The 27,063 square foot Community Centered Property was 44% leased as of March 31, 2017 and is located in Scottsdale, Arizona, and adjacent to Pinnacle of Scottsdale.

On December 31, 2016, we had substantially completed construction at our Shops at Starwood Phase III property. As of March 31, 2017, we had incurred approximately $7.6 million in construction costs, including approximately $0.8 million in previously capitalized interest and real estate taxes. The 35,351 square foot Community Centered Property was 50% leased as of March 31, 2017 and is located in Frisco, Texas, a northern suburb of Dallas, Texas, and adjacent to Shops at Starwood.

Property dispositions. On March 3, 2016, we completed the sale of Brookhill, located in Houston, Texas, for $3.1 million. This disposition was pursuant to our strategy of recycling capital by disposing of non-core properties, primarily properties that we owned at the time our current management team assumed the management of the Company, that do not fit our Community Centered Property™ strategy. We recorded a gain on sale of $1.9 million. The sale was structured as a like-kind exchange within the meaning of Section 1031 of the Code and sales proceeds were deposited into a Section 1031 exchange escrow account with a qualified intermediary and subsequently distributed for general corporate purposes. We have not included Brookhill in discontinued operations as it did not meet the definition of discontinued operations.

On February 17, 2016, we completed the sale of approximately 0.5 acres of our 4.5 acre Pinnacle Phase II development parcel, located in Scottsdale, Arizona, for $1.1 million. We recorded a gain on sale of $1.0 million.

SUBSEQUENT EVENTS

Pending Acquisitions

On April 19, 2017, we announced the pending acquisitions of two retail centers located at BLVD Place in Houston, Texas and Eldorado Plaza in McKinney, Texas, respectively, each of which is a property that meets our Community Centered Property™ strategy, for an aggregate purchase price of $204.6 million in cash. On May 3, 2017, we acquired Eldorado Plaza. Pursuant to the purchase agreement governing the acquisition of BLVD Place, we expect the closing of BLVD Place to occur in May 2017.

The closing of BLVD Place is not subject to a financing condition. We funded the purchase price of Eldorado Plaza and related transaction expenses through a combination of net proceeds from the April Offering (as defined below) and borrowings under our Facility. We expect to fund the purchase price of the acquisition of BLVD Place and related transaction expenses through a combination of net proceeds from the April Offering (as defined below), and $80 million of asset level mortgage financing (the “BLVD Financing”). We are currently negotiating the terms of the BLVD Financing with potential lenders, however we have not yet entered into a binding commitment letter or definitive loan documents and there can be no assurance that we will obtain the BLVD Financing on the terms we anticipate or at all. The consummation of the BLVD Place acquisition is not contingent on obtaining the BLVD Financing and, in the event we do not obtain the BLVD Financing, we expect to fund the purchase price of the BLVD Place acquisition through a combination of net proceeds from the April Offering, as discussed below, and borrowings under our Facility. In addition, pursuant to the purchase agreements governing the acquisition of BLVD Place, the closing of BLVD Place is subject to the satisfaction or waiver of certain customary closing conditions. There can be no assurance that the closing of the acquisition of BLVD Place will occur in accordance with the anticipated timeline or at all. See “Risk Factors - There can be no assurance that the acquisition of BLVD Place will be consummated or that the BLVD Financing will be obtained in accordance with the anticipated timing or at all.”

April Offering

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 purchase price of $12.48 per share (the “April Offering”). Total net proceeds from the April 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 intends to use the net proceeds from the April Offering initially to repay a portion of outstanding indebtedness under the Facility, which amounts will then become available for future borrowings, including the funding of a portion of the purchase price of the acquisitions of Eldorado Plaza and BLVD Place or for general corporate purposes.

Eldorado Plaza Acquisition

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 from borrowings under our Facility. 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.

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 March 31, 2017 and December 31, 2016, 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. We also consolidate a variable interest entity (“VIE”) when we are determined to be the primary beneficiary. Determination of the primary beneficiary is based on whether an entity has (1) the power to direct activities that most significantly impact the economic performance of the VIE and (2) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Our determination of the primary beneficiary considers all relationships between us and the VIE, including management and other contractual agreements. See Note 6 for additional disclosure on our VIE.

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 period. 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.

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. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities as of 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 period amounts in the accompanying consolidated financial statements in order to be consistent with the current period presentation. These reclassifications had no effect on net income, total assets, total liabilities or equity.

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.

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 (See Note 7), 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. As a result, these amounts are reported in the consolidated statements of cash flows under cash flows from financing activities as change in restricted cash.

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 (loss) and subsequently reclassified into earnings in the period that the hedged transaction affects earnings. Any ineffective portion of a cash flow hedges' 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 March 31, 2017, we consider our cash flow hedges to be highly effective.

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. For the three months ended March 31, 2017, approximately $72,000 and $29,000 in interest expense and real estate taxes, respectively, were capitalized, and for the three months ended March 31, 2016, approximately $27,000 and $16,000 in interest expense and real estate taxes, respectively, were capitalized.

Real Estate Held for Sale and Discontinued Operations

Real Estate Held for Sale and Discontinued Operations. We consider a commercial property to be held for sale when it meets all of the criteria established under ASC 205, “Presentation of Financial Statements.” For commercial properties classified as held for sale, assets and liabilities are presented separately for all periods presented.

In accordance with ASC 205,a discontinued operation may include a component of an entity or a group of components of an entity. A disposal of a component of an entity or a group of components of an entity is reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results when the component of an entity or group of components of an entity is classified as held for sale, disposed of by sale or disposed of other than by sale, respectively. In addition, ASC 205 requires us to provide additional disclosures about both discontinued operations and the disposal of an individually significant component of an entity that does not meet the criteria for a discontinued operation.

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 2008 Long-Term Equity Incentive Ownership Plan (the “2008 Plan”).  The vast majority of the 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 $2,451,000 and $2,025,000 in share-based compensation for the three months ended March 31, 2017 and 2016, respectively.

Noncontrolling Interests

Noncontrolling Interests.  Noncontrolling interests is 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, subsidiaries are reported at the consolidated amount, including both the amount attributable to Whitestone and noncontrolling interests.  The consolidated statement of changes in equity is included for quarterly financial statements, including beginning balances, activity for the period and ending balances for shareholders' equity, noncontrolling interests and total equity.

Recent Accounting Pronouncements

Recent Accounting Pronouncements.  In February 2016, the FASB issued guidance requiring lessees to recognize a lease liability and a right-of-use asset for all leases. Lessor accounting will remain largely unchanged with the exception of changes related to costs which qualify as initial direct costs. The guidance will also require new qualitative and quantitative disclosures to help financial statement users better understand the timing, amount and uncertainty of cash flows arising from leases. This guidance will be effective for reporting periods beginning on or after December 15, 2018, with early adoption permitted. We are currently evaluating the impact of this guidance and its impact on our consolidated financial statements.

In March 2016, the FASB issued guidance simplifying the accounting for share-based payment transactions, including the income tax consequences, balance sheet classification of awards and the classification on the statement of cash flows. We have adopted this guidance as of January 1, 2017. The main provision regarding excess tax benefits did not have an impact on our consolidated financial statements due to our status as a REIT for taxation purposes. We have elected to continue estimating the number of shares expected to vest in order to determine compensation cost, and we will continue to classify cash paid by us for employee taxes when common shares were repurchased to cover minimum statutory requirements as financing activity.

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 will become effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We are currently evaluating the impact of this guidance and its impact on our consolidated financial statements.

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 disposals) of assets or businesses. This guidance will become effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We are currently evaluating the impact of this guidance and its impact on our consolidated financial statements.

In February 2017, the FASB issued guidance clarifying the scope of asset derecognition guidance, adds guidance for partial sales of nonfinancial assets and clarifies recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. This guidance will become effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We are currently evaluating the impact of this guidance and its impact on our consolidated financial statements.
