Amendment Description	Restatement of Consolidated Financial Statements This Amendment No. 1 on Form 10-Q/A (this “Form 10-Q/A”) amends and restates certain items noted below in the quarterly report on Form 10-Q of Pillarstone Capital REIT (the “Company”) for the period ended March 31, 2018, as originally filed with the Securities and Exchange Commission (the “SEC”) on May 14, 2018 (the “Original Filing”). This Form 10-Q/A restates the Company's consolidated financial statements and related disclosures for the period ended March 31, 2018 to reflect the correction of an accounting error described below. Background and Effect of Restatement As previously disclosed, on December 8, 2016, the Company and Pillarstone Capital REIT Operating Partnership LP, a subsidiary and the operating partnership of the Company (the “Operating Partnership” or “Pillarstone OP”), entered into a Contribution Agreement (the “Contribution Agreement”) with Whitestone REIT Operating Partnership, L.P. (“Whitestone OP”), a subsidiary and the operating partnership of Whitestone REIT (“Whitestone”), both of which are related parties to the Company and the Operating Partnership. Pursuant to the Contribution Agreement, Whitestone OP contributed to the Operating Partnership all of the equity interests in four of its wholly-owned subsidiaries (the "Subsidiaries"): Whitestone CP Woodland Ph. 2, LLC, a Delaware limited liability company; Whitestone Industrial-Office, LLC, a Texas limited liability company; Whitestone Offices, LLC, a Texas limited liability company; and Whitestone Uptown Tower, LLC, a Delaware limited liability company. The Subsidiaries own 14 real estate assets and, in exchange for this contribution, Whitestone OP received aggregate consideration of approximately $84.0 million, consisting of (i) approximately $18.1 million of Class A units representing limited partnership interests in the Operating Partnership (“OP Units”), issued at a price of $1.331 per OP Unit; and (ii) the assumption of approximately $65.9 million of liabilities by the Operating Partnership (collectively, the “Acquisition”). The Company is the general partner of the Operating Partnership and, immediately after the Acquisition, had an equity ownership interest in the Operating Partnership representing approximately 18.6% and valued at approximately $4.1 million. In connection with the Contribution Agreement, on December 8, 2016, the Company, as the general partner of the Operating Partnership, entered into an Amended and Restated Agreement of Limited Partnership of the Operating Partnership (as amended and restated, the “Limited Partnership Agreement”). Pursuant to the Limited Partnership Agreement, subject to certain protective rights of the limited partners described below, the general partner has responsibility and discretion in the management and control of the Operating Partnership, including the ability to cause the Operating Partnership to enter into certain major transactions including a merger of the Operating Partnership or a sale of substantially all of the assets of the Operating Partnership. The limited partners have no power to remove the general partner without the general partner's consent. In addition, pursuant to the Limited Partnership Agreement, the general partner may not conduct any business other than in connection with the ownership, acquisition and disposition of the Operating Partnership’s interest and management of its business without the consent of a majority of the limited partners other than in connection with certain actions described therein. As such, the Company was deemed to exercise significant influence but not complete control over the Operating Partnership. As of the date of the Acquisition, the Company determined that it was not the primary beneficiary of the Operating Partnership under the variable interest entity (“VIE”) rules prescribed by U.S. generally accepted accounting principles (“U.S. GAAP”), and thus the Company’s investment in the Operating Partnership qualified for usage of the equity method of accounting. In November 2017, the Company and Whitestone each received a comment letter from the Staff (the “Staff”) of the Division of Corporation Finance of the SEC relating to the Company’s and Whitestone’s Annual Reports on Form 10-K for the year ended December 31, 2016. In their letters, the Staff requested that the Company and Whitestone provide them with an analysis to support the determination that the Operating Partnership is a VIE of which Whitestone is the primary beneficiary. In response to the Staff’s comment, Whitestone, on its own behalf and on behalf of the Company, provided the Staff with its analysis of Whitestone’s accounting and financial reporting obligations relating to its interest in the Operating Partnership. After communicating its analysis and conclusions to the Staff and responding to additional questions from the Staff relating to this matter, the Staff did not object to or otherwise take exception to the initial determinations at the time of the consummation of the Acquisition in December 2016 but provided a verbal reminder in that the determination of the primary beneficiary of a VIE should be continually reassessed, and recommended that Whitestone consider pre-clearing future accounting treatment of the Operating Partnership with the Staff of the Office of the Chief Accountant (“OCA”). In connection with the preparation and review of its financial statements for the quarter ended March 31, 2018, Whitestone concluded, in accordance with the Staff’s recommendation, and after consultation with its outside accounting advisors, that it would be prudent to seek pre-clearance from the OCA of Whitestone's proposed treatment of the Operating Partnership in its financial statements for such quarter. Accordingly, in April 2018, Whitestone submitted a letter to the OCA seeking their concurrence with its determinations that Whitestone maintained its status as the primary beneficiary of the Operating Partnership and, accordingly, should continue to consolidate the Operating Partnership in its financial statements for the quarter ended March 31, 2018 in accordance U.S. GAAP. After further correspondence, including telephonic meetings between Whitestone, its advisors and the OCA, the OCA informed Whitestone that it objected to Whitestone’s and the Company’s conclusions that Whitestone was the primary beneficiary of the Operating Partnership since the Acquisition in December 2016 and during the subsequent periods. Whitestone and the Company respectfully disagreed with the OCA’s determination and Whitestone, on its own behalf and on behalf of the Company, made a formal appeal to the Chief Accountant of the SEC in June 2018. In July 2018, Whitestone and its advisory team of accounting and legal professionals met with the Chief Accountant, members of the OCA and Division of Corporate Finance. On July 30, 2018, the Chief Accountant of the SEC informed Whitestone that its formal appeal was denied and that the OCA objected to Whitestone’s and the Company’s presentation of their investments in the Operating Partnership under the VIE accounting guidance since the consummation of the Acquisition in December 2016. As a result, the Company’s management has determined that the Company should not have used the equity method of accounting to present its investment in the Operating Partnership in its audited consolidated financial statements for the years ended December 31, 2016 and December 31, 2017 and unaudited consolidated financial statements for the quarters ended March 31, 2017; June 30, 2017; September 30, 2017 and March 31, 2018 (collectively, the “Prior Period Financial Statements”). After consideration of the OCA’s objection to Whitestone’s original accounting, the Company evaluated its original accounting of the equity method and the materiality of the error quantitatively and qualitatively and concluded that it was material to the Prior Period Financial Statements. The Company revised its original accounting treatment accordingly in the amended filings. The Company determined that it is the primary beneficiary of the Operating Partnership through the Company's power to direct the activities that most significantly impact the Operating Partnership’s economic performance and the Company's right to receive benefits based on its ownership percentage in the Operating Partnership. Accordingly, the Company accounts for the Operating Partnership as a VIE and fully consolidates it in the Company's financial statements. Whitestone OP’s 81.4% interest in the Operating Partnership will be accounted for as a non-controlling interest and is deducted from the Company’s share of net income and equity in the Operating Partnership. Items Amended in This Filing This Form 10-Q/A amends and restates the following indicated parts of the Original Filing: Item 1. Financial Statements Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations Item 4. Controls and Procedures

Accounting Changes and Error Corrections [Abstract]
Restatement of Consolidated Financial Statements	RESTATEMENT OF CONSOLIDATED FINANCIAL STATEMENTS In November 2017, the Company and Whitestone each received a comment letter from the Staff (the “Staff”) of the Division of Corporation Finance of the SEC relating to the Company’s and Whitestone’s Annual Reports on Form 10-K for the year ended December 31, 2016.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 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. In order to conform with U.S. GAAP, management, in preparation of our consolidated financial statements, is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of March 31, 2018 and December 31, 2017 , and the reported amounts of revenues and expenses for the three months ended March 31, 2018 and 2017 . Actual results could differ from those estimates. Significant estimates include fair value of properties acquired, estimated useful lives of properties, allowance for bad debt, impairment, deferred taxes and the related valuation allowance for deferred taxes, and these significant estimates, as well as other estimates and assumptions, may change in the near term. Cash and cash equivalents. We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents as of March 31, 2018 and December 31, 2017 consisted of demand deposits at commercial banks and brokerage accounts. We maintain our cash in bank accounts that are federally insured. Acquired Properties and Acquired Lease Intangibles. We allocate the purchase price of the acquired properties to land, building and improvements, identifiable intangible assets and to the acquired liabilities based on their respective fair values at the time of purchase. Identifiable intangibles include amounts allocated to acquired out-of-market leases, the value of in-place leases and customer relationship value, if any. We determine fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends and specific market and economic conditions that may affect the property. Factors considered by management in our analysis of determining the as-if-vacant property value include an estimate of carrying costs during the expected lease-up periods considering market conditions, and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and estimates of lost rentals at market rates during the expected lease-up periods, tenant demand and other economic conditions. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related expenses. Intangibles related to out-of-market leases and in-place lease value are recorded as acquired lease intangibles and are amortized as an adjustment to rental revenue or amortization expense, as appropriate, over the remaining terms of the underlying leases. Premiums or discounts on acquired out-of-market debt are amortized to interest expense over the remaining term of such debt. Depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of 5 to 39 years for improvements and buildings, respectively. Tenant improvements are depreciated using the straight-line method over the life of the improvement or remaining term of the lease, whichever is shorter. Impairment. We review our properties for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations. We determine whether an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of the property, with the carrying cost of the property. If impairment is indicated, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value. Management has determined that there has been no impairment in the carrying value of our real estate assets as of March 31, 2018 . Accrued Rents and Accounts Receivable. Included in accrued rent and accounts receivable are base rents, tenant reimbursements and receivables attributable to recording rents on a straight-line basis. An allowance for the uncollectible portion of accrued rents and accounts receivable is determined based upon customer credit-worthiness (including expected recovery of our claim with respect to any tenants in bankruptcy), historical bad debt levels, and current economic trends. As of March 31, 2018 and December 31, 2017 , we had an allowance for uncollectible accounts of approximately $579,000 and $539,000 , respectively. For the three months ended March 31, 2018 and 2017 , we had bad debt expense of approximately $40,000 and $70,000 , respectively. Unamortized Lease Commissions and Deferred Legal Costs. Leasing commissions and deferred legal costs are amortized using the straight-line method over the terms of the related lease agreements. Loan costs are amortized on the straight-line method over the terms of the loans, which approximates the interest method. Costs allocated to in-place leases whose terms differ from market terms related to acquired properties are amortized over the remaining life of the respective leases. Prepaids and Other assets . Prepaids and other assets include escrows established pursuant to certain mortgage financing arrangements for real estate taxes and insurance. Noncontrolling Interests. Noncontrolling interests are the portion of equity in a subsidiary not attributable to a parent. The ownership interests not held by the parent are considered noncontrolling interests. Accordingly, we have reported noncontrolling interest in equity on the consolidated balance sheets but separate from Pillarstone’s equity. On the consolidated statements of operations, subsidiaries are reported at the consolidated amount, including both the amount attributable to Pillarstone and noncontrolling interest. Revenue recognition . All leases on our properties are classified as operating leases, and the related rental income is recognized on a straight-line basis over the terms of the related leases. Differences between rental income earned and amounts due per the respective lease agreements are capitalized or charged, as applicable, to accrued rents and accounts receivable. Percentage rents are recognized as rental income when the thresholds upon which they are based have been met. Recoveries from tenants for taxes, insurance, and other operating expenses are recognized as revenues in the period the corresponding costs are incurred. We have established an allowance for doubtful accounts against the portion of tenant accounts receivable which is estimated to be uncollectible. Stock-based compensation . The Company accounts for stock-based compensation in accordance with ASC 718, "Compensation - Stock Compensation," which addresses the accounting for stock-based payment transactions in which an enterprise receives employee services in exchange for (a) equity instruments of the enterprise or (b) liabilities that are based on the fair value of the enterprise’s equity instruments or that may be settled by the issuance of such equity instruments. ASC 718 generally requires that these transactions be accounted for using a fair-value-based method. The Company uses the Black-Scholes option-pricing model to determine the fair-value of stock-based awards. Income taxes . Because we have not elected to be taxed as a REIT for federal income tax purposes, we account for income taxes using the liability method under which deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect for the period in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We are also subject to certain state and local income, excise and franchise taxes. The provision for state and local taxes has been reflected in provision for income taxes in the consolidated statements of operations and has not been separately stated due to its insignificance. The Company evaluates potential uncertain tax positions on an annual basis in conjunction with the board of trustees and its tax accountants. Authoritative literature provides a two-step approach to recognize and measure tax benefits when realization of the benefits is uncertain. The first step is to determine whether the benefit meets the more-likely-than-not condition for recognition and the second step is to determine the amount to be recognized based on the cumulative probability that exceeds 50% . The Company has no uncertain tax positions that required adjustments to our consolidated financial statements in 2018 or 2017. Concentration of Risk. Substantially all of our revenues are obtained from office and warehouse locations in the Dallas-Fort Worth and Houston metropolitan areas. We maintain cash accounts in major U.S. financial institutions. The terms of these deposits are on demand to minimize risk. The balances of these accounts sometimes exceed the federally insured limits, although no losses have been incurred in connection with these deposits. Recent accounting pronouncements . In May 2014, the FASB issued guidance, as amended in subsequent updates, establishing a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance. The standard also requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and also requires certain additional disclosures. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We have adopted this guidance on a modified retrospective basis beginning January 1, 2018, and the adoption of this guidance did not have a material impact on our consolidated financial statements. 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 will adopt this guidance on a modified retrospective basis beginning January 1, 2019, and such adoption will result in certain costs (primarily legal costs related to lease negotiations) being expensed rather than capitalized. We capitalized $4,000 in legal related costs for the three months ended March 31, 2018. In November 2016, the FASB issued guidance requiring that the statement of cash flows explain the change during the period in the total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance effective January 1, 2018, and we have reconciled cash and cash equivalents and restricted cash and restricted cash equivalents on a retrospective basis, whereas under the previous guidance, we reported restricted cash and restricted cash equivalents under cash flows from financing activities. In January 2017, the FASB issued guidance clarifying the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a prospective basis beginning January 1, 2018 and believe the majority of our future acquisitions will qualify as asset acquisitions and the associated transaction costs will be capitalized as opposed to expensed under previous guidance. In February 2017, the FASB issued guidance clarifying the scope of asset derecognition guidance, added guidance for partial sales of nonfinancial assets and clarified recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a modified retrospective basis beginning January 1, 2018, and the adoption of this guidance did not have a material impact on our consolidated financial statements.

Equity Method Investments and Joint Ventures [Abstract]
Variable Interest Entity	VARIABLE INTEREST ENTITY On December 8, 2016, Pillarstone and Pillarstone OP, entered into a Contribution Agreement (the “Contribution Agreement”) with Whitestone REIT Operating Partnership, L.P. (“Whitestone OP”), a subsidiary and the operating partnership of Whitestone REIT (“Whitestone”), both of which are related parties to Pillarstone and Pillarstone OP, pursuant to which Whitestone OP contributed to Pillarstone OP all of the equity interests in four of its wholly-owned subsidiaries, the “Subsidiaries”): Whitestone CP Woodland Ph. 2, LLC, a Delaware limited liability company; Whitestone Industrial-Office, LLC, a Texas limited liability company; Whitestone Offices, LLC, a Texas limited liability company; and Whitestone Uptown Tower, LLC, a Delaware limited liability company (“Uptown Tower”). The Subsidiaries own 14 real estate assets (the “Real Estate Assets” and, together with the Subsidiaries, the “Property”) for aggregate consideration of approximately $84 million , consisting of (i) approximately $18.1 million of Class A units representing limited partnership interests in Pillarstone OP (“OP Units”), issued at a price of $1.331 per OP Unit; and (ii) the assumption of approximately $65.9 million of liabilities by Pillarstone OP. Pillarstone is the general partner of Pillarstone OP and, as a result of the Contribution Agreement, has equity ownership interest in Pillarstone OP totaling approximately 18.6% valued at approximately $4.1 million as of the date of the agreement. In connection with the Contribution Agreement, on December 8, 2016, the Company, as the general partner of Pillarstone OP, entered into an Amended and Restated Agreement of Limited Partnership of Pillarstone OP (as amended and restated, the “Amended and Restated Agreement of Limited Partnership”). Pursuant to the Amended and Restated Agreement of Limited Partnership, subject to certain protective rights of the limited partners described below, the general partner has full, exclusive and complete responsibility and discretion in the management and control of Pillarstone OP, including the ability to cause Pillarstone OP to enter into certain major transactions including a merger of Pillarstone OP or a sale of substantially all of the assets of Pillarstone OP. The limited partners have no power to remove the general partner without the general partner's consent. In addition, pursuant to the Amended and Restated Agreement of Limited Partnership, the general partner may not conduct any business without the consent of a majority of the limited partners other than in connection with certain actions described therein. The Company is deemed to exercise significant influence over Pillarstone OP as it has the power to direct the activities that most significantly impact Pillarstone OP's economic performance and the Company's right to receive benefits based on its ownership percentage in Pillarstone OP. Accordingly, the Company accounts for Pillarstone OP as a VIE. The Amended and Restated Agreement of Limited Partnership designates two classes of units of limited partnership interest in Pillarstone OP: the OP Units and LTIP units. In general, LTIP units are similar to the OP Units and will receive the same quarterly per-unit profit distributions as the OP Units. The rights, privileges, and obligations related to each series of LTIP units will be established at the time the LTIP units are issued. As profits interests, LTIP units initially will not have full parity, on a per-unit basis, with OP Units with respect to liquidating distributions. Upon the occurrence of specified events, LTIP units can over time achieve full parity with the OP Units and therefore accrete to an economic value for the holder equivalent to OP Units. If such parity is achieved, vested LTIP units may be converted on a one -for-one basis into OP Units, which in turn are redeemable by the holder for cash or, at the Company’s election, exchangeable for Common Shares on a one -for-one basis. During the period from December 8, 2016 through December 31, 2016, Pillarstone received a distribution in kind equal to the value of the original investment of $4.1 million . The carrying amounts and classification of certain assets and liabilities for Pillarstone OP in our consolidated balance sheet as of March 31, 2018 and December 31, 2017 consists of the following (in thousands): March 31, 2018 December 31, 2017 Real estate assets, at cost Property $ 83,810 $ 83,141 Accumulated depreciation (3,672 ) (2,934 ) Total real estate assets 80,138 80,207 Cash and cash equivalents 2,361 2,812 Escrows and acquisition deposits 1,133 2,188 Accrued rents and accounts receivable, net of allowance for doubtful accounts 1,400 798 Receivable due from related party 699 1,304 Unamortized lease commissions and deferred legal costs, net 1,238 1,265 Prepaid expenses and other assets 94 150 Total assets $ 87,063 $ 88,724 Liabilities: Notes payable $ 64,013 $ 64,313 Accounts payable and accrued expenses 1,944 3,494 Payable due to related party 885 1,005 Tenants' security deposits 1,262 1,191 Total liabilities $ 68,104 $ 70,003 (1) Excludes approximately $0.3 million in accounts receivable due from Pillarstone that was eliminated in consolidation as of March 31, 2018 and December 31, 2017 .

Summary of Significant Accoun16

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	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. In order to conform with U.S. GAAP, management, in preparation of our consolidated financial statements, is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of March 31, 2018 and December 31, 2017 , and the reported amounts of revenues and expenses for the three months ended March 31, 2018 and 2017 . Actual results could differ from those estimates. Significant estimates include fair value of properties acquired, estimated useful lives of properties, allowance for bad debt, impairment, deferred taxes and the related valuation allowance for deferred taxes, and these significant estimates, as well as other estimates and assumptions, may change in the near term.
Cash and cash equivalents	Cash and cash equivalents. We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents as of March 31, 2018 and December 31, 2017 consisted of demand deposits at commercial banks and brokerage accounts. We maintain our cash in bank accounts that are federally insured.
Acquired Properties and Acquired Lease Intangibles	Acquired Properties and Acquired Lease Intangibles. We allocate the purchase price of the acquired properties to land, building and improvements, identifiable intangible assets and to the acquired liabilities based on their respective fair values at the time of purchase. Identifiable intangibles include amounts allocated to acquired out-of-market leases, the value of in-place leases and customer relationship value, if any. We determine fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends and specific market and economic conditions that may affect the property. Factors considered by management in our analysis of determining the as-if-vacant property value include an estimate of carrying costs during the expected lease-up periods considering market conditions, and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and estimates of lost rentals at market rates during the expected lease-up periods, tenant demand and other economic conditions. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related expenses. Intangibles related to out-of-market leases and in-place lease value are recorded as acquired lease intangibles and are amortized as an adjustment to rental revenue or amortization expense, as appropriate, over the remaining terms of the underlying leases. Premiums or discounts on acquired out-of-market debt are amortized to interest expense over the remaining term of such debt.
Depreciation	Depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of 5 to 39 years for improvements and buildings, respectively. Tenant improvements are depreciated using the straight-line method over the life of the improvement or remaining term of the lease, whichever is shorter.
Impairment	Impairment. We review our properties for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of the assets, including accrued rental income, may not be recoverable through operations. We determine whether an impairment in value has occurred by comparing the estimated future cash flows (undiscounted and without interest charges), including the estimated residual value of the property, with the carrying cost of the property. If impairment is indicated, a loss will be recorded for the amount by which the carrying value of the property exceeds its fair value. Management has determined that there has been no impairment in the carrying value of our real estate assets as of March 31, 2018 .
Accrued Rents and Accounts Receivable	Accrued Rents and Accounts Receivable. Included in accrued rent and accounts receivable are base rents, tenant reimbursements and receivables attributable to recording rents on a straight-line basis. An allowance for the uncollectible portion of accrued rents and accounts receivable is determined based upon customer credit-worthiness (including expected recovery of our claim with respect to any tenants in bankruptcy), historical bad debt levels, and current economic trends.
Unamortized Lease Commissions and Deferred Legal Costs	Unamortized Lease Commissions and Deferred Legal Costs. Leasing commissions and deferred legal costs are amortized using the straight-line method over the terms of the related lease agreements. Loan costs are amortized on the straight-line method over the terms of the loans, which approximates the interest method. Costs allocated to in-place leases whose terms differ from market terms related to acquired properties are amortized over the remaining life of the respective leases.
Prepaids and Other assets	Prepaids and Other assets . Prepaids and other assets include escrows established pursuant to certain mortgage financing arrangements for real estate taxes and insurance.
Noncontrolling Interests	Noncontrolling Interests. Noncontrolling interests are the portion of equity in a subsidiary not attributable to a parent. The ownership interests not held by the parent are considered noncontrolling interests. Accordingly, we have reported noncontrolling interest in equity on the consolidated balance sheets but separate from Pillarstone’s equity. On the consolidated statements of operations, subsidiaries are reported at the consolidated amount, including both the amount attributable to Pillarstone and noncontrolling interest.
Revenue recognition	Revenue recognition . All leases on our properties are classified as operating leases, and the related rental income is recognized on a straight-line basis over the terms of the related leases. Differences between rental income earned and amounts due per the respective lease agreements are capitalized or charged, as applicable, to accrued rents and accounts receivable. Percentage rents are recognized as rental income when the thresholds upon which they are based have been met. Recoveries from tenants for taxes, insurance, and other operating expenses are recognized as revenues in the period the corresponding costs are incurred. We have established an allowance for doubtful accounts against the portion of tenant accounts receivable which is estimated to be uncollectible.
Stock-based compensation	Stock-based compensation . The Company accounts for stock-based compensation in accordance with ASC 718, "Compensation - Stock Compensation," which addresses the accounting for stock-based payment transactions in which an enterprise receives employee services in exchange for (a) equity instruments of the enterprise or (b) liabilities that are based on the fair value of the enterprise’s equity instruments or that may be settled by the issuance of such equity instruments. ASC 718 generally requires that these transactions be accounted for using a fair-value-based method. The Company uses the Black-Scholes option-pricing model to determine the fair-value of stock-based awards.
Income Taxes	Income taxes . Because we have not elected to be taxed as a REIT for federal income tax purposes, we account for income taxes using the liability method under which deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect for the period in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We are also subject to certain state and local income, excise and franchise taxes. The provision for state and local taxes has been reflected in provision for income taxes in the consolidated statements of operations and has not been separately stated due to its insignificance. The Company evaluates potential uncertain tax positions on an annual basis in conjunction with the board of trustees and its tax accountants. Authoritative literature provides a two-step approach to recognize and measure tax benefits when realization of the benefits is uncertain. The first step is to determine whether the benefit meets the more-likely-than-not condition for recognition and the second step is to determine the amount to be recognized based on the cumulative probability that exceeds 50% .
Concentration of Risk	Concentration of Risk. Substantially all of our revenues are obtained from office and warehouse locations in the Dallas-Fort Worth and Houston metropolitan areas. We maintain cash accounts in major U.S. financial institutions. The terms of these deposits are on demand to minimize risk. The balances of these accounts sometimes exceed the federally insured limits, although no losses have been incurred in connection with these deposits.
Recent accounting pronouncements	Recent accounting pronouncements . In May 2014, the FASB issued guidance, as amended in subsequent updates, establishing a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance. The standard also requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and also requires certain additional disclosures. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We have adopted this guidance on a modified retrospective basis beginning January 1, 2018, and the adoption of this guidance did not have a material impact on our consolidated financial statements. 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 will adopt this guidance on a modified retrospective basis beginning January 1, 2019, and such adoption will result in certain costs (primarily legal costs related to lease negotiations) being expensed rather than capitalized. We capitalized $4,000 in legal related costs for the three months ended March 31, 2018. In November 2016, the FASB issued guidance requiring that the statement of cash flows explain the change during the period in the total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance effective January 1, 2018, and we have reconciled cash and cash equivalents and restricted cash and restricted cash equivalents on a retrospective basis, whereas under the previous guidance, we reported restricted cash and restricted cash equivalents under cash flows from financing activities. In January 2017, the FASB issued guidance clarifying the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a prospective basis beginning January 1, 2018 and believe the majority of our future acquisitions will qualify as asset acquisitions and the associated transaction costs will be capitalized as opposed to expensed under previous guidance. In February 2017, the FASB issued guidance clarifying the scope of asset derecognition guidance, added guidance for partial sales of nonfinancial assets and clarified recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. This guidance became effective for the reporting periods beginning on or after December 15, 2017, and interim periods within those fiscal years. We adopted this guidance on a modified retrospective basis beginning January 1, 2018, and the adoption of this guidance did not have a material impact on our consolidated financial statements.
