BASIS OF PRESENTATION

Description of Business

Cousins Properties Incorporated (“Cousins”), a Georgia corporation, is a self-administered and self-managed real estate investment trust (“REIT”). Through December 31, 2014, Cousins Real Estate Corporation (“CREC”) was a taxable entity wholly-owned by and consolidated with Cousins. CREC owned, developed, and managed its own real estate portfolio and performed certain real estate related services for other parties. On December 31, 2014, CREC merged into Cousins and coincident with this merger, Cousins formed Cousins TRS Services LLC ("CTRS"), a new taxable entity wholly-owned by Cousins. Upon formation, CTRS received a capital contribution of some of the real estate assets and contracts that were previously owned by CREC. CTRS owns and manages its own real estate portfolio and performs certain real estate related services for other parties. Cousins, CREC, CTRS and their subsidiaries are included in the condensed consolidated financial statements and are hereinafter referred to collectively as the "Company."

The Company develops, acquires, leases, manages, and owns primarily Class A office properties and opportunistic mixed-use properties in Sunbelt markets with a focus on Georgia, Texas, and North Carolina. Cousins has elected to be taxed as a real estate investment trust (“REIT”) and intends to, among other things, distribute 90% of its net taxable income to stockholders, thereby eliminating any liability for federal income taxes under current law. Therefore, the results included herein do not include a federal income tax provision for Cousins.

Basis of Presentation

The condensed consolidated financial statements are unaudited and were prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission (“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 the Company's financial position as of September 30, 2015 and the results of operations for the three and nine months ended September 30, 2015 and 2014. The results of operations for the three and nine months ended September 30, 2015 are not necessarily indicative of 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 condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K/A for the year ended December 31, 2014. The accounting policies employed are substantially the same as those shown in note 2 to the consolidated financial statements included in such Form 10-K/A.

For the three and nine months ended September 30, 2015 and 2014, there were no items of other comprehensive income. Therefore, no presentation of comprehensive income is required.

The Company evaluates all partnerships, joint ventures and other arrangements with variable interests to determine if the entity or arrangement qualifies as a variable interest entity (“VIE”), as defined in the Financial Accounting Standards Board's ("FASB") Accounting Standards Codification ("ASC"). If the entity or arrangement qualifies as a VIE and the Company is determined to be the primary beneficiary, the Company is required to consolidate the assets, liabilities, and results of operations of the VIE.

In July 2015, the Company acquired land and transferred it to a special purpose entity to facilitate a potential Section 1031 exchange under the Internal Revenue Code. To realize the tax deferral available under the Section 1031 exchange, the Company must complete the Section 1031 exchange, and take title to the to-be-exchanged land within 180 days of the acquisition date. The Company has determined that this entity is a VIE, and the Company is the primary beneficiary. Therefore, the Company consolidates this entity. As of September 30, 2015, this VIE had total assets of $34.1 million, no significant liabilities, and no significant cash flows.

Certain prior year amounts have been reclassified for consistency with the current period presentation. In the first quarter of 2015, the Company concluded that certain liabilities associated with variable stock-based compensation should be classified as other liabilities. Previously, these items had been classified as accounts payable and accrued expenses. This change in classification does not affect the previously reported Condensed Consolidated Statement of Cash Flows or Condensed Consolidated Statement of Operations for any period.

Recent Accounting Pronouncements

In February 2015, the FASB issued ASC 2015-02 "Consolidation (Topic 810): Amendments to the Consolidation Analysis." All legal entities are subject to reevaluation under the revised consolidation model. The amendment modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities or voting interest entities. It also eliminates the presumption that a general partner should consolidate a limited partnership. The guidance is effective for public entities with periods beginning after December 15, 2015 with early adoption permitted. The Company expects to adopt this guidance effective January 1, 2016 and is currently assessing the potential impact of adopting the new guidance.

In April 2015, the FASB issued ASU 2015-03, "Simplifying the Presentation of Debt Issuance Costs," which will require companies to present debt issuance costs as a direct deduction from the related debt rather than as an asset. These costs will continue to be amortized into interest expense. The guidance is effective for periods beginning after December 15, 2015 with early adoption permitted. The Company expects to adopt this guidance effective January 1, 2016, and the Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

In April 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. The Company expects to adopt this guidance effective January 1, 2018 and is currently assessing the potential impact of adopting the new guidance.
