Organization	Organization Parkway, Inc. (the "Company") was incorporated as a Maryland corporation on June 3, 2016 and was capitalized on June 29, 2016. As of September 30, 2016, the Company’s sole stockholder was Parkway Properties, Inc., a Maryland corporation (“Legacy Parkway”). On April 28, 2016, the board of directors of Cousins Properties Incorporated, a Georgia corporation (“Cousins”), and the board of directors of Legacy Parkway, each approved an Agreement and Plan of Merger, dated as of April 28, 2016 (the “Merger Agreement”). On October 6, 2016, pursuant to the Merger Agreement, Legacy Parkway merged with and into Clinic Sub Inc., with Clinic Sub Inc. continuing as the surviving corporation and a wholly owned subsidiary of Cousins (the “Merger”). Immediately following the effective time of the Merger, in accordance with the Merger Agreement, Cousins separated the portion of its combined businesses relating to the ownership of real properties in Houston, Texas, as well as Legacy Parkway’s fee-based real estate services (the “Third-Party Services Business” and together with the Houston real properties, the “Houston Business”), from the remainder of the combined businesses (the “Separation”). In connection with the Separation, Cousins and Legacy Parkway reorganized the combined businesses through a series of transactions (the “Reorganization”) pursuant to which the Houston Business was transferred to the Company. On October 7, 2016, Cousins completed the Spin-Off of the Company by distributing all of the outstanding shares of common and limited voting stock of the Company to the holders of Cousins common and limited voting preferred stock as of the record date, October 6, 2016 (the “Spin-Off”). Following the Merger and Spin-Off, the Company owns and operates five office assets with 8.7 million rentable square feet (unaudited) in the Galleria, Greenway and Westchase submarkets of Houston, Texas. In addition, the Company operates the Third-Party Services Business through a wholly owned subsidiary, Eola Office Partners, LLC and its wholly owned subsidiaries (collectively, “Eola”), which in total managed and/or leased approximately 4.0 million square feet (unaudited) for primarily third-party owners as of September 30, 2016 . As of September 30, 2016 , the Company had not conducted any business as a separate company other than start-up related activities.

Organization	Organization And Basis Of Presentation Merger and Spin-Off On October 6, 2016, Cousins Properties Incorporated (“Cousins”) and Parkway Properties, Inc. (“Legacy Parkway”) completed a stock-for-stock merger (the “Merger”), followed on October 7, 2016 by a spin-off (the “Spin-Off”) of the combined Houston-based assets of both companies (the “Houston Business”) into a new publicly traded real estate investment trust, Parkway, Inc. (the “Company”). Basis of Presentation The combined financial statements included herein represent the combined accounts and combined operations of the portion of the Houston Business owned and operated by Cousins (“Cousins Houston”). Cousins Houston includes the combined accounts related to the office properties of Greenway Plaza and Post Oak Central, operated prior to the Merger and the Spin-Off through subsidiaries of Cousins as of and for the three months ended September 30, 2016, and certain corporate costs. The assets and liabilities in these combined financial statements represent historical carrying amounts of the following properties: Acquisition Date Number of Office Buildings Total Square Feet Post Oak Central February 7, 2013 3 1,280,000 Greenway Plaza September 9, 2013 10 4,348,000 13 5,628,000 Cousins Houston is a predecessor, as defined in applicable rules and regulations of the Securities and Exchange Commission (the “SEC”), to the Company which commenced operations upon completion of the Spin-Off. The combined financial statements are unaudited and were prepared by Cousins Houston in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and in accordance with the rules and regulations of the SEC. In the opinion of management, these financial statements reflect all adjustments necessary (which adjustments are of a normal and recurring nature) for the fair presentation of Cousins Houston’s financial position as of September 30, 2016 and the results of operations for the three and nine months ended September 30, 2016 and 2015. The results of operations for the three and nine months ended September 30, 2016 are not necessarily indicative of the results expected for the full year. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. These combined financial statements should be read in conjunction with the consolidated financial statements and the notes thereto as of December 31, 2015 and 2014 and for the years ended December 31, 2015 and 2014 and for the period from February 7, 2013 (date of inception) to December 31, 2013 included in the Company's Information Statement dated September 27, 2016. The accounting policies employed are substantially the same as those shown in Note 2 to those financial statements. For the periods presented, there were no items of other comprehensive income. Therefore, no presentation of comprehensive income is required. Allocated Costs The historical financial results for Cousins Houston include certain allocated corporate costs which Cousins Houston believes are reasonable. These costs were incurred by Cousins and estimated to be applicable to Cousins Houston based on proportionate leasable square footage. Such costs do not necessarily reflect what the actual costs would have been if Cousins Houston were operating as an independent, stand-alone public company. Additionally, the historical results for Cousins Houston include transaction costs that were incurred by Cousins related to the Spin-Off. These costs are discussed further in Note 3—Related Party Transactions. Recently Issued Accounting Standards In 2015, the Financial Accounting Standards Board (the “FASB”) voted to defer ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” Under the new guidance, companies will recognize revenue when the seller satisfies a performance obligation, which would be when the buyer takes control of the good or service. This new guidance could result in different amounts of revenue being recognized and could result in revenue being recognized in different reporting periods than under the current guidance. The standard specifically excludes revenue associated with lease contracts. The guidance is effective for periods beginning after December 15, 2017, with early adoption permitted for periods beginning after December 15, 2016. Management is currently assessing the potential impact of adopting the new guidance. In February 2016, the FASB issued ASU 2016-02, “Leases,” which amends the existing standards for lease accounting by requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting and reporting. The new standard will require lessees to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months, and classify such leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method (finance leases) or on a straight-line basis over the term of the lease (operating leases). Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. ASU 2016-02 supersedes previous leasing standards. The guidance is effective for the fiscal years beginning after December 15, 2018 with early adoption permitted.

Basis of Presentation and Consolidation/Significant Accounting Policies	Basis of Presentation Basis of Presentation The accompanying financial statements have been prepared by the Company's management (“management”) in accordance with accounting principles generally accepted in the United States (“GAAP”). In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. For periods presented prior to the date of the Spin-Off, the historical consolidated financial results for the Company reflect charges for certain costs related to the Spin-Off which were incurred directly by the Company, or by Legacy Parkway, on the Company's behalf, and, to the extent such amounts were paid by Legacy Parkway, are reflected as equity contributions. In each case, these charges were allocated to the Company based on an analysis of key metrics such as leasable square feet or personnel hours, and accordingly, the Company believes the allocations are reasonable. Such costs do not necessarily reflect what the actual costs would have been if the Company were operating as an independent, stand-alone public company. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from these estimates and assumptions. Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less to be cash equivalents. Capitalization of Costs Costs related to planning and pre-development are capitalized in Other Assets.
Cousins Houston
Real Estate Properties [Line Items]
Basis of Presentation and Consolidation/Significant Accounting Policies	Significant Accounting Policies Real Estate Assets Cost Capitalization Cousins Houston capitalizes costs related to property and tenant improvements, including allocated costs of Cousins’ personnel working directly on projects. Cousins Houston capitalizes direct leasing costs related to leases that are probable of being executed. These costs include commissions paid to outside brokers, legal costs incurred to negotiate and document a lease agreement, and costs incurred by personnel of Cousins that are based on time spent on successful leases. Cousins Houston allocates these costs to individual tenant leases and amortizes them over the related lease term. Impairment For real estate assets that are considered to be held for sale according to accounting guidance, Cousins Houston records impairment losses if the fair value of the asset net of estimated selling costs is less than the carrying amount. For those long-lived assets that are held and used according to accounting guidance, management reviews each asset for the existence of any indicators of impairment. If indicators of impairment are present, Cousins Houston calculates the expected undiscounted future cash flows to be derived from such assets. If the undiscounted cash flows are less than the carrying amount of the asset, Cousins Houston reduces the asset to its fair value. Acquisition of Operating Properties Cousins Houston records the acquired tangible and intangible assets and assumed liabilities of operating property acquisitions at fair value at the acquisition date. The acquired assets and assumed liabilities for an operating property acquisition generally include but are not limited to: land, buildings and improvements, and identified tangible and intangible assets and liabilities associated with in-place leases, including leasing costs, value of above-market and below-market tenant leases, value of above-market and below-market ground leases, acquired in-place lease values, and tenant relationships, if any. The fair value of land is derived from comparable sales of land within the same submarket and/or region. The fair value of buildings and improvements, tenant improvements, and leasing costs are based upon current market replacement costs and other relevant market rate information. The fair value of the above-market or below-market component of an acquired in-place lease is based upon the present value (calculated using a market discount rate) of the difference between (i) the contractual rents to be paid pursuant to the lease over its remaining term and (ii) management’s estimate of the rents that would be paid using fair market rental rates and rent escalations at the date of acquisition over the remaining term of the lease. The amounts recorded for above-market and below-market leases are included in intangible assets and intangible liabilities, respectively, and are amortized on a straight-line basis into rental property operating revenues over the remaining terms of the applicable leases. The fair value of acquired in-place leases is derived based on management’s assessment of lost revenue and costs incurred for the period required to lease the “assumed vacant” property to the occupancy level when purchased. The amount recorded for acquired in-place leases is included in intangible assets and amortized as an increase to depreciation and amortization expense over the remaining term of the applicable leases. Depreciation and Amortization Real estate assets are stated at depreciated cost less impairment losses, if any. Buildings are depreciated over their estimated useful lives, which range from 30 to 42 years . The life of a particular building depends upon a number of factors including whether the building was developed or acquired and the condition of the building upon acquisition. Furniture, fixtures and equipment are depreciated over their estimated useful lives of five years . Tenant improvements, leasing costs and leasehold improvements are amortized over the term of the applicable leases or the estimated useful life of the assets, whichever is shorter. Cousins Houston accelerates the depreciation of tenant assets if it estimates that the lease term will end prior to the termination date. This acceleration may occur if a tenant files for bankruptcy, vacates its premises or defaults in another manner on its lease. Deferred expenses are amortized over the period of estimated benefit. Cousins Houston uses the straight-line method for all depreciation and amortization. Revenue Recognition Cousins Houston recognizes contractual revenues from leases on a straight-line basis over the term of the respective lease. In addition, leases typically provide for reimbursement of the tenants’ share of real estate taxes, insurance, and other operating expenses to Cousins Houston. Operating expense reimbursements are recognized as the related expenses are incurred. For the three months ended September 30, 2016 and 2015, Cousins Houston recognized $16.8 million and $15.8 million , respectively, in revenues from tenants for reimbursements of operating expenses, and recognized $46.6 million and $45.0 million in the nine months ended September 30, 2016 and 2015, respectively. Cousins Houston makes valuation adjustments to all tenant-related accounts receivable based upon its estimate of the likelihood of collectability. The amount of any valuation adjustment is based on the tenant’s credit and business risk, history of payment, and other factors considered by management. Income Taxes Through October 6, 2016, Cousins Houston’s properties were owned by Cousins, a Georgia corporation which has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”). As a REIT, Cousins is not subject to federal income tax provided it distributes annually its adjusted taxable income, as defined in the Code, to stockholders and meets certain other organizational and operating requirements. Accordingly, the combined financial statements of Cousins Houston do not include a provision for federal income tax. Cash and Cash Equivalents Cash and cash equivalents include cash and highly-liquid money market instruments with maturities of three months or less. Segment Disclosure Cousins Houston is in the business of the ownership, development and management of office real estate. Cousins Houston has aggregated its office operations into one reportable segment. This segment is the aggregation of the aforementioned Cousins Houston office properties as reported to the Chief Operating Decision Maker and is aggregated due to the properties having similar economic and geographic characteristics. Fair Value Measurements Level 1 fair value inputs are quoted prices for identical items in active, liquid and visible markets such as stock exchanges. Level 2 fair value inputs are observable information for similar items in active or inactive markets and appropriately consider counterparty creditworthiness in the valuations. Level 3 fair value inputs reflect Cousins Houston’s best estimate of inputs and assumptions market participants would use in pricing an asset or liability at the measurement date. The inputs are unobservable in the market and significant to the valuation estimate. Cousins Houston has no investments for which fair value is measured on a recurring basis using Level 3 inputs. Note 5 includes fair values of debt measured using Level 2 inputs. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Parkway Houston
Real Estate Properties [Line Items]
Basis of Presentation and Consolidation/Significant Accounting Policies	Basis of Presentation and Consolidation The accompanying combined financial statements include the accounts of Parkway Houston presented on a combined basis as the ownership interests previously were under common control and ownership of Legacy Parkway during the reported periods. All significant intercompany balances and transactions have been eliminated. These combined financial statements are derived from the books and records of Legacy Parkway and were carved out from Legacy Parkway at a carrying value reflective of such historical cost in such Legacy Parkway records. Parkway Houston’s historical financial results reflect charges for certain corporate costs and Parkway Houston believes such charges are reasonable; however, such results do not necessarily reflect what Parkway Houston's expenses would have been had Parkway Houston been operating as an independent, stand-alone public company. Costs of the services that were charged to Parkway Houston were based on either actual costs incurred or a proportion of costs estimated to be applicable to Parkway Houston. The historical combined financial information presented may therefore not be indicative of the results of operations, financial position or cash flows that would have been obtained if Parkway Houston had been an independent, stand-alone public company during the periods presented or of Parkway Houston's future performance as an independent, stand-alone company. Parkway Houston is a predecessor, as defined in applicable rules and regulations for the Securities and Exchange Commission, to the Company, which commenced operations on the date of the Spin-Off. These combined financial statements reflect the consolidation of properties that are wholly owned or properties in which, prior to the Merger, the Separation, the Reorganization and the Spin-off, Legacy Parkway owned less than a 100% interest but that Legacy Parkway controlled. Control of a property is demonstrated by, among other factors, Parkway Houston's ability to refinance debt and sell the property without the consent of any other partner or owner and the inability of any other partner or owner to replace Legacy Parkway. Eola, Phoenix Tower, CityWestPlace and San Felipe Plaza were all wholly owned by Legacy Parkway for all periods presented. Parkway Houston consolidates its Murano residential condominium project which it controls. Parkway Houston’s unaffiliated partner’s interest is reflected on its combined balance sheets under the “Noncontrolling Interests” caption. Parkway Houston’s partner has a stated ownership interest of 27% . Net proceeds from the project will be distributed, to the extent available, based on an order of preferences described in the partnership agreement. Parkway Houston may receive distributions, if any, in excess of its stated 73% ownership interest if certain return thresholds are met. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Although management believes the assumptions and estimates made are reasonable and appropriate, as discussed in the applicable sections throughout these combined financial statements, different assumptions and estimates could materially impact reported results. The current economic environment has increased the degree of uncertainty inherent in these estimates and assumptions; therefore, changes in market conditions could impact Parkway Houston's future operating results. The Company’s most significant estimates relate to impairments on real estate and other assets and purchase price assignments. Actual results may differ from these estimates and assumptions. Recent Accounting Pronouncements Adopted In February 2015, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Updates (“ASU”) No. 2015-02, “Amendments to the Consolidated Analysis.” This update amends consolidation guidance which makes changes to both the variable interest model and the voting model. The new standard specifically eliminates the presumption in the current voting model that a general partner controls a limited partnership or similar entity unless that presumption can be overcome. Generally, only a single limited partner that is able to exercise substantive kick-out rights will consolidate. Parkway Houston adopted this update on January 1, 2016. The new standard must be applied using a modified retrospective approach by recording either a cumulative-effect adjustment to equity as of the beginning of the period of adoption or retrospectively to each period presented. This did not have an impact on Parkway Houston’s financial statements. In April 2015, the FASB issued ASU No. 2015-03, “Simplifying the Presentation of Debt Issuance Costs.” This standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. Parkway Houston adopted this update on January 1, 2016. Retrospective application of the guidance set forth in this update is required and resulted in the classification of the deferred financing costs within the combined balance sheets as a direct deduction from the carrying amount of debt within total liabilities. Not Yet Adopted In 2015, the FASB voted to defer ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” Under the new guidance, companies will recognize revenue when the seller satisfies a performance obligation, which would be when the buyer takes control of the good or service. This new guidance could result in different amounts of revenue being recognized and could result in revenue being recognized in different reporting periods than under the current guidance. The standard specifically excludes revenue associated with lease contracts. The guidance is effective for periods beginning after December 15, 2017, with early adoption permitted for periods beginning after December 15, 2016. Management is currently assessing the potential impact of adopting the new guidance. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). ASU 2016-02 increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 will be effective for Parkway Houston’s fiscal year beginning as early as January 1, 2019 and subsequent interim periods. Management is currently assessing this guidance for future implementation.

Mortgage Notes Payable, Net/Note Payable	Note Payable In September 2013, Cousins Houston entered into a $188.8 million non-recourse mortgage note payable secured by Post Oak Central. The note bears interest at 4.26% , and the maturity date is October 1, 2020. In connection with this note payable, Cousins Houston incurred $1.2 million in loan costs. These costs, net of accumulated amortization of $550,000 and $416,000 at September 30, 2016 and December 31, 2015, respectively, are reflected as a reduction of the loan balance on the accompanying balance sheets. Fair value of debt is calculated by discounting the debt’s remaining contractual cash flows at estimated rates at which similar loans could have been obtained. The estimate of the current market rate is intended to replicate debt of similar maturity and loan-to-value relationship. These fair value calculations are considered to be Level 2 under the guidelines set forth in ASC 820, as Cousins Houston utilizes market rates for similar type loans from third party brokers. At September 30, 2016 and 2015, the fair value of this financial instrument and the related discount rate assumptions are summarized as follows (dollars in thousands): September 30, 2016 December 31, 2015 Carrying value $ 178,471 $ 180,937 Fair value 185,800 186,449 Discount rate assumed in calculating fair value 3.25 % 3.65 %

Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters using the latest information available. Cousins Houston records a liability for litigation if an unfavorable outcome is probable and the amount of loss or range of loss can be reasonably estimated. If an unfavorable outcome is probable and a reasonable estimate of the loss is a range, Cousins Houston accrues the best estimate within the range. If no amount within the range is a better estimate than any other amount, Cousins Houston accrues the minimum amount within the range. If an unfavorable outcome is probable but the amount of the loss cannot be reasonably estimated, Cousins Houston discloses the nature of the litigation and indicates that an estimate of the loss or range of loss cannot be made. If an unfavorable outcome is reasonably possible and the estimated loss is material, Cousins Houston discloses the nature and estimate of the possible loss of the litigation. Cousins Houston does not disclose information with respect to litigation where an unfavorable outcome is considered to be remote or where the estimated loss would not be material.

In connection with the Separation and the Reorganization, on October 6, 2016, the Company and the Operating Partnership, as borrower, entered into a credit agreement providing for (i) a three -year, $100 million senior secured revolving credit facility (the “Revolving Credit Facility”), and (ii) a three -year, $350 million senior secured term loan facility (the “Term Loan” and, together with the Revolving Credit Facility, the “Facilities”), with Bank of America, N.A., as Administrative Agent and the lenders party thereto (collectively, the “Lenders”). The Facilities each have an initial maturity date of October 6, 2019, but are subject in each case to a one -year extension option at the election of the Operating Partnership. The exercise of the extension option requires the payment of an extension fee and the satisfaction of certain other customary conditions. The credit agreement also permits the Operating Partnership to utilize up to $15 million of the Revolving Credit Facility for the issuance of letters of credit. Interest on the Facilities will accrue at a rate based on LIBOR or a base rate, in each case, plus an applicable margin. The Facilities will be prepayable at the election of the borrower (upon not less than three business days’ written notice to the administrative agent) without premium or penalty (other than customary breakage fees), and will not require any scheduled repayments of principal prior to the maturity date. The Facilities are guaranteed pursuant to a Guaranty Agreement entered into on October 6, 2016, by the Company, all wholly owned material subsidiaries of the Operating Partnership that are not otherwise prohibited from guarantying the Facilities, Parkway Properties General Partners, Inc. and Parkway Properties LP. As of October 6, 2016, no amounts had been drawn on the Revolving Credit Facility and the Term Loan was fully funded. In connection with the Separation and Reorganization, the Company contributed approximately $167 million of the proceeds of the Term Loan, directly or indirectly, to Cousins Properties LP, which used such funds to repay certain indebtedness of Cousins and its subsidiaries, including Legacy Parkway’s previously-existing credit facilities. The Operating Partnership has retained the remaining proceeds of the Term Loan as working capital that will be used for the general corporate purposes of the Operating Partnership. In connection with the Spin-Off on October 7, 2016, the Company entered into a Stockholders Agreement with TPG VI Pantera Holdings, L.P. (“TPG Pantera”) and TPG VI Management, LLC (“TPG Management,” and together with TPG Pantera, the “TPG Parties”), in order to establish various arrangements and restrictions with respect to governance of the Company and certain rights with respect to common stock of the Company owned by the TPG Parties.

Basis of Presentation	Basis of Presentation The accompanying financial statements have been prepared by the Company's management (“management”) in accordance with accounting principles generally accepted in the United States (“GAAP”). In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. For periods presented prior to the date of the Spin-Off, the historical consolidated financial results for the Company reflect charges for certain costs related to the Spin-Off which were incurred directly by the Company, or by Legacy Parkway, on the Company's behalf, and, to the extent such amounts were paid by Legacy Parkway, are reflected as equity contributions. In each case, these charges were allocated to the Company based on an analysis of key metrics such as leasable square feet or personnel hours, and accordingly, the Company believes the allocations are reasonable. Such costs do not necessarily reflect what the actual costs would have been if the Company were operating as an independent, stand-alone public company.
Cost Capitalization	Capitalization of Costs Costs related to planning and pre-development are capitalized in Other Assets.
Cash and Cash Equivalents	Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less to be cash equivalents.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from these estimates and assumptions.
Cousins Houston
Real Estate Properties [Line Items]
Basis of Presentation	The combined financial statements included herein represent the combined accounts and combined operations of the portion of the Houston Business owned and operated by Cousins (“Cousins Houston”). Cousins Houston includes the combined accounts related to the office properties of Greenway Plaza and Post Oak Central, operated prior to the Merger and the Spin-Off through subsidiaries of Cousins as of and for the three months ended September 30, 2016, and certain corporate costs. The assets and liabilities in these combined financial statements represent historical carrying amounts of the following properties: Acquisition Date Number of Office Buildings Total Square Feet Post Oak Central February 7, 2013 3 1,280,000 Greenway Plaza September 9, 2013 10 4,348,000 13 5,628,000 Cousins Houston is a predecessor, as defined in applicable rules and regulations of the Securities and Exchange Commission (the “SEC”), to the Company which commenced operations upon completion of the Spin-Off. The combined financial statements are unaudited and were prepared by Cousins Houston in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and in accordance with the rules and regulations of the SEC. In the opinion of management, these financial statements reflect all adjustments necessary (which adjustments are of a normal and recurring nature) for the fair presentation of Cousins Houston’s financial position as of September 30, 2016 and the results of operations for the three and nine months ended September 30, 2016 and 2015. The results of operations for the three and nine months ended September 30, 2016 are not necessarily indicative of the results expected for the full year. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. These combined financial statements should be read in conjunction with the consolidated financial statements and the notes thereto as of December 31, 2015 and 2014 and for the years ended December 31, 2015 and 2014 and for the period from February 7, 2013 (date of inception) to December 31, 2013 included in the Company's Information Statement dated September 27, 2016. The accounting policies employed are substantially the same as those shown in Note 2 to those financial statements. For the periods presented, there were no items of other comprehensive income. Therefore, no presentation of comprehensive income is required.
Cost Capitalization	Cost Capitalization Cousins Houston capitalizes costs related to property and tenant improvements, including allocated costs of Cousins’ personnel working directly on projects. Cousins Houston capitalizes direct leasing costs related to leases that are probable of being executed. These costs include commissions paid to outside brokers, legal costs incurred to negotiate and document a lease agreement, and costs incurred by personnel of Cousins that are based on time spent on successful leases. Cousins Houston allocates these costs to individual tenant leases and amortizes them over the related lease term.
Impairment	Impairment For real estate assets that are considered to be held for sale according to accounting guidance, Cousins Houston records impairment losses if the fair value of the asset net of estimated selling costs is less than the carrying amount. For those long-lived assets that are held and used according to accounting guidance, management reviews each asset for the existence of any indicators of impairment. If indicators of impairment are present, Cousins Houston calculates the expected undiscounted future cash flows to be derived from such assets. If the undiscounted cash flows are less than the carrying amount of the asset, Cousins Houston reduces the asset to its fair value.
Acquisition of Operating Properties	Acquisition of Operating Properties Cousins Houston records the acquired tangible and intangible assets and assumed liabilities of operating property acquisitions at fair value at the acquisition date. The acquired assets and assumed liabilities for an operating property acquisition generally include but are not limited to: land, buildings and improvements, and identified tangible and intangible assets and liabilities associated with in-place leases, including leasing costs, value of above-market and below-market tenant leases, value of above-market and below-market ground leases, acquired in-place lease values, and tenant relationships, if any. The fair value of land is derived from comparable sales of land within the same submarket and/or region. The fair value of buildings and improvements, tenant improvements, and leasing costs are based upon current market replacement costs and other relevant market rate information. The fair value of the above-market or below-market component of an acquired in-place lease is based upon the present value (calculated using a market discount rate) of the difference between (i) the contractual rents to be paid pursuant to the lease over its remaining term and (ii) management’s estimate of the rents that would be paid using fair market rental rates and rent escalations at the date of acquisition over the remaining term of the lease. The amounts recorded for above-market and below-market leases are included in intangible assets and intangible liabilities, respectively, and are amortized on a straight-line basis into rental property operating revenues over the remaining terms of the applicable leases. The fair value of acquired in-place leases is derived based on management’s assessment of lost revenue and costs incurred for the period required to lease the “assumed vacant” property to the occupancy level when purchased. The amount recorded for acquired in-place leases is included in intangible assets and amortized as an increase to depreciation and amortization expense over the remaining term of the applicable leases.
Depreciation and Amortization	Depreciation and Amortization Real estate assets are stated at depreciated cost less impairment losses, if any. Buildings are depreciated over their estimated useful lives, which range from 30 to 42 years . The life of a particular building depends upon a number of factors including whether the building was developed or acquired and the condition of the building upon acquisition. Furniture, fixtures and equipment are depreciated over their estimated useful lives of five years . Tenant improvements, leasing costs and leasehold improvements are amortized over the term of the applicable leases or the estimated useful life of the assets, whichever is shorter. Cousins Houston accelerates the depreciation of tenant assets if it estimates that the lease term will end prior to the termination date. This acceleration may occur if a tenant files for bankruptcy, vacates its premises or defaults in another manner on its lease. Deferred expenses are amortized over the period of estimated benefit. Cousins Houston uses the straight-line method for all depreciation and amortization. Depreciation and Amortization Real estate assets are stated at depreciated cost less impairment losses, if any.

Cousins Houston uses the straight-line method for all depreciation and amortization.
Revenue Recognition	Revenue Recognition Cousins Houston recognizes contractual revenues from leases on a straight-line basis over the term of the respective lease. In addition, leases typically provide for reimbursement of the tenants’ share of real estate taxes, insurance, and other operating expenses to Cousins Houston. Operating expense reimbursements are recognized as the related expenses are incurred. For the three months ended September 30, 2016 and 2015, Cousins Houston recognized $16.8 million and $15.8 million , respectively, in revenues from tenants for reimbursements of operating expenses, and recognized $46.6 million and $45.0 million in the nine months ended September 30, 2016 and 2015, respectively. Cousins Houston makes valuation adjustments to all tenant-related accounts receivable based upon its estimate of the likelihood of collectability. The amount of any valuation adjustment is based on the tenant’s credit and business risk, history of payment, and other factors considered by management.
Income Taxes	Income Taxes Through October 6, 2016, Cousins Houston’s properties were owned by Cousins, a Georgia corporation which has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”). As a REIT, Cousins is not subject to federal income tax provided it distributes annually its adjusted taxable income, as defined in the Code, to stockholders and meets certain other organizational and operating requirements. Accordingly, the combined financial statements of Cousins Houston do not include a provision for federal income tax.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash and highly-liquid money market instruments with maturities of three months or less.
Segment Disclosure	Segment Disclosure Cousins Houston is in the business of the ownership, development and management of office real estate. Cousins Houston has aggregated its office operations into one reportable segment. This segment is the aggregation of the aforementioned Cousins Houston office properties as reported to the Chief Operating Decision Maker and is aggregated due to the properties having similar economic and geographic characteristics.
Fair Value Measurements	Fair Value Measurements Level 1 fair value inputs are quoted prices for identical items in active, liquid and visible markets such as stock exchanges. Level 2 fair value inputs are observable information for similar items in active or inactive markets and appropriately consider counterparty creditworthiness in the valuations. Level 3 fair value inputs reflect Cousins Houston’s best estimate of inputs and assumptions market participants would use in pricing an asset or liability at the measurement date. The inputs are unobservable in the market and significant to the valuation estimate. Cousins Houston has no investments for which fair value is measured on a recurring basis using Level 3 inputs. Note 5 includes fair values of debt measured using Level 2 inputs.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In 2015, the Financial Accounting Standards Board (the “FASB”) voted to defer ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” Under the new guidance, companies will recognize revenue when the seller satisfies a performance obligation, which would be when the buyer takes control of the good or service. This new guidance could result in different amounts of revenue being recognized and could result in revenue being recognized in different reporting periods than under the current guidance. The standard specifically excludes revenue associated with lease contracts. The guidance is effective for periods beginning after December 15, 2017, with early adoption permitted for periods beginning after December 15, 2016. Management is currently assessing the potential impact of adopting the new guidance. In February 2016, the FASB issued ASU 2016-02, “Leases,” which amends the existing standards for lease accounting by requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting and reporting. The new standard will require lessees to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months, and classify such leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method (finance leases) or on a straight-line basis over the term of the lease (operating leases). Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. ASU 2016-02 supersedes previous leasing standards. The guidance is effective for the fiscal years beginning after December 15, 2018 with early adoption permitted. Management is currently assessing the potential impact of adopting the new guidance.
Parkway Houston
Real Estate Properties [Line Items]
Basis of Presentation	The accompanying combined financial statements include the accounts of Parkway Houston presented on a combined basis as the ownership interests previously were under common control and ownership of Legacy Parkway during the reported periods. All significant intercompany balances and transactions have been eliminated. These combined financial statements are derived from the books and records of Legacy Parkway and were carved out from Legacy Parkway at a carrying value reflective of such historical cost in such Legacy Parkway records. Parkway Houston’s historical financial results reflect charges for certain corporate costs and Parkway Houston believes such charges are reasonable; however, such results do not necessarily reflect what Parkway Houston's expenses would have been had Parkway Houston been operating as an independent, stand-alone public company. Costs of the services that were charged to Parkway Houston were based on either actual costs incurred or a proportion of costs estimated to be applicable to Parkway Houston. The historical combined financial information presented may therefore not be indicative of the results of operations, financial position or cash flows that would have been obtained if Parkway Houston had been an independent, stand-alone public company during the periods presented or of Parkway Houston's future performance as an independent, stand-alone company. Parkway Houston is a predecessor, as defined in applicable rules and regulations for the Securities and Exchange Commission, to the Company, which commenced operations on the date of the Spin-Off.
Consolidation	These combined financial statements reflect the consolidation of properties that are wholly owned or properties in which, prior to the Merger, the Separation, the Reorganization and the Spin-off, Legacy Parkway owned less than a 100% interest but that Legacy Parkway controlled. Control of a property is demonstrated by, among other factors, Parkway Houston's ability to refinance debt and sell the property without the consent of any other partner or owner and the inability of any other partner or owner to replace Legacy Parkway.
Use of Estimates	The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Although management believes the assumptions and estimates made are reasonable and appropriate, as discussed in the applicable sections throughout these combined financial statements, different assumptions and estimates could materially impact reported results. The current economic environment has increased the degree of uncertainty inherent in these estimates and assumptions; therefore, changes in market conditions could impact Parkway Houston's future operating results. The Company’s most significant estimates relate to impairments on real estate and other assets and purchase price assignments. Actual results may differ from these estimates and assumptions.
Recently Issued Accounting Standards	Recent Accounting Pronouncements Adopted In February 2015, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Updates (“ASU”) No. 2015-02, “Amendments to the Consolidated Analysis.” This update amends consolidation guidance which makes changes to both the variable interest model and the voting model. The new standard specifically eliminates the presumption in the current voting model that a general partner controls a limited partnership or similar entity unless that presumption can be overcome. Generally, only a single limited partner that is able to exercise substantive kick-out rights will consolidate. Parkway Houston adopted this update on January 1, 2016. The new standard must be applied using a modified retrospective approach by recording either a cumulative-effect adjustment to equity as of the beginning of the period of adoption or retrospectively to each period presented. This did not have an impact on Parkway Houston’s financial statements. In April 2015, the FASB issued ASU No. 2015-03, “Simplifying the Presentation of Debt Issuance Costs.” This standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. Parkway Houston adopted this update on January 1, 2016. Retrospective application of the guidance set forth in this update is required and resulted in the classification of the deferred financing costs within the combined balance sheets as a direct deduction from the carrying amount of debt within total liabilities. Not Yet Adopted In 2015, the FASB voted to defer ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” Under the new guidance, companies will recognize revenue when the seller satisfies a performance obligation, which would be when the buyer takes control of the good or service. This new guidance could result in different amounts of revenue being recognized and could result in revenue being recognized in different reporting periods than under the current guidance. The standard specifically excludes revenue associated with lease contracts. The guidance is effective for periods beginning after December 15, 2017, with early adoption permitted for periods beginning after December 15, 2016. Management is currently assessing the potential impact of adopting the new guidance. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). ASU 2016-02 increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 will be effective for Parkway Houston’s fiscal year beginning as early as January 1, 2019 and subsequent interim periods. Management is currently assessing this guidance for future implementation.
