BASIS OF PRESENTATION	'
	BASIS OF PRESENTATION
	The condensed consolidated financial statements included herein include the accounts of Cousins Properties Incorporated (“Cousins”) and its consolidated subsidiaries, including Cousins Real Estate Corporation and its subsidiaries (“CREC”). All of the entities included in the condensed consolidated financial statements are hereinafter referred to collectively as the “Company.”
	The Company develops, acquires, leases, manages, and owns primarily Class A office assets 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. CREC operates as a taxable REIT subsidiary and is taxed separately from Cousins as a C-Corporation. Accordingly, if applicable, the Company's statements of operations include a provision for, or benefit from, CREC's income taxes.
	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, 2014 and the results of operations for the three and nine months ended September 30, 2014 and 2013. The results of operations for the three and nine months ended September 30, 2014 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 for the year ended December 31, 2013. 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.
	For the three and nine months ended September 30, 2014 and 2013, 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 August 2014, the Company acquired a building 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, if any, and take title to the to-be-exchanged building 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, 2014, this VIE had total assets of $215.0 million, no significant liabilities, and no significant cash flows.
	In April 2014, the FASB issued new guidance related to the presentation of discontinued operations. Prior to this new guidance, the Company included activity for all assets held for sale and disposals in discontinued operations on the statements of operations. Under the new guidance, only assets held for sale and disposals representing a major strategic shift in operations, such as the disposal of a line of business, a significant geographical area, or a major equity investment, will be presented as discontinued operations. Additionally, the new guidance requires expanded disclosures about discontinued operations that will provide more information about their assets, liabilities, income, and expenses. The guidance is effective for periods beginning after December 15, 2014. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued. The Company adopted this guidance in 2014.
	In May 2014, the FASB issued new guidance related to the accounting for revenue from contracts with customers. 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 it is under the current guidance. The new guidance specifically excludes revenue associated with lease contracts. The guidance is effective for periods beginning after December 15, 2016 and early adoption is prohibited.

	Discontinued Operations
	In April 2014, the FASB issued new guidance related to the presentation of discontinued operations, which changed the accounting criteria for discontinued operations. See footnote 1 for further information. The new guidance applies to assets that are sold or meet the criteria for held for sale after the date of adoption. The Company adopted the new standard in 2014. As a result, two of the Company’s properties that became held for sale in the third quarter of 2014 (777 Main and Mahan Village) that under the previous guidance would have been considered discontinued operations are not considered discontinued operations under the new guidance.
	The following properties met the criteria for discontinued operations presentation prior to the adoption of the new guidance discussed above.  Accordingly, the results of operations of these properties are included in a separate section, discontinued operations, in the statements of operations for all periods presented ($ in thousands):

Subsequent Event
In October 2014, the Company acquired Northpark Town Center, a 1.5 million square foot office asset located in Atlanta, Georgia. The gross purchase price for this property was $348.0 million, before adjustments for customary closing costs and other closing credits. The Company funded the purchase of Northpark Town Center with cash on hand and borrowings under its Credit Facility. As of September 30, 2014, the Company had incurred $385,000 in acquisition and related costs associated with this acquisition, and the Company expects to incur additional acquisition and related costs in the fourth quarter. Due to the limited time since the acquisition date, the initial accounting for this transaction is incomplete and, as such, the Company is unable to provide purchase price allocation disclosures.

								$	671,074			$	630,094
	In the third quarter of 2014, the Mahan Village construction facility's maturity date was extended from September 2014 to January 2015.
	On May 28, 2014, the Company entered into a Third Amended and Restated Credit Agreement (the “New Facility”) under which the Company may borrow up to $500 million if certain conditions are satisfied. The New Facility recast the Company's existing $350 million senior unsecured revolving line of credit, dated February 28, 2012 (the “Existing Facility”) by:
	•	Increasing the size by $150 million to $500 million;
	•	Extending the maturity date from February 28, 2016 to May 28, 2019;
	•	Reducing the per annum variable interest rate spread and other fees; and
	•	Providing for the expansion of the New Facility by an additional $250 million for a total available of $750 million, subject to receipt of additional commitments from lenders and other customary conditions.
	The New Facility contains certain financial covenants that require, among other things, the maintenance of an unencumbered interest coverage ratio of at least 2.00; a fixed charge coverage ratio of at least 1.50; an overall leverage ratio of no more than 60%; and a minimum shareholders’ equity in an amount equal to $1.0 billion, plus a portion of the net cash proceeds from certain equity issuances. The New Facility also contains customary representations and warranties and affirmative and negative covenants, as well as customary events of default. The amounts outstanding under the New Facility may be accelerated upon the occurrence of any events of default.
	The interest rate applicable to the New Facility varies according to the Company’s leverage ratio, and may, at the election of the Company, be determined based on either (1) the current LIBOR plus the applicable spread detailed below, or (2) the greater of Bank of America’s prime rate, the federal funds rate plus 0.50% or the one-month LIBOR plus 1.0% (the “Base Rate”), plus the applicable spread detailed below. Fees on letters of credit issued under the New Facility are payable at an annual rate equal to the spread applicable to loans bearing interest based on LIBOR. The Company also pays an annual facility fee on the total commitments under the New Facility. The pricing spreads and the facility fee under the New Facility are as follows:
	Leverage Ratio		Applicable % Spread for LIBOR Loans		Applicable % Spread for Base Rate Loans		Annual Facility Fee %
	≤ 30%		1.10%		0.10%		0.15%
	> 30% but ≤ 35%		1.10%		0.10%		0.20%
	> 35% but ≤ 40%		1.15%		0.15%		0.20%
	> 40% but ≤ 45%		1.20%		0.20%		0.20%
	> 45% but ≤ 50%		1.20%		0.20%		0.25%
	> 50%		1.45%		0.45%		0.30%
	At September 30, 2014, the Company's spread over LIBOR was 1.10%. The New Facility also provides for alternative pricing spreads and facility fees, which would be available to the Company on any date after the Company obtains an investment grade credit rating.
	Fair Value
	At September 30, 2014 and December 31, 2013, the aggregate estimated fair values of the Company's notes payable were $711.3 million and $654.1 million, respectively, calculated by discounting the debt's remaining contractual cash flows at estimated rates at which similar loans could have been obtained at those respective dates. The estimate of the current market rate, which is the most significant input in the discounted cash flow calculation, 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 as set forth in ASC 820, Fair Value Measurement, as the Company utilizes market rates for similar type loans from third party brokers.
	Other Information
	For the three and nine months ended September 30, 2014 and 2013, interest expense was as follows (in thousands):

	Total interest expense	$	6,817			$	5,149			$	20,954			$	14,325
	The real estate and other assets of The American Cancer Society Center (the “ACS Center”) are restricted under the ACS Center loan agreement in that they are not available to settle debts of the Company. However, provided that the ACS Center loan has not incurred any uncured event of default, as defined in the loan agreement, the cash flows from the ACS Center, after payments of debt service, operating expenses and reserves, are available for distribution to the Company.
	Subsequent Events
	On October 1, 2014, the Company acquired Northpark Town Center as discussed in note 2 and funded the acquisition with cash on hand and with borrowings under its Credit Facility. On October 14, 2014, the Company entered into an $85.0 million mortgage note secured by 816 Congress. This mortgage note has a fixed rate of 3.75% and matures in November 2024. The Company used the proceeds from this mortgage note to reduce amounts outstanding under its Credit Facility. As of October 24, 2014, the amount outstanding under the Company's Credit Facility was $318.2 million.

	Litigation
	The Company is subject to various legal proceedings, claims and administrative proceedings arising in the ordinary course of business, some of which are expected to be covered by liability insurance. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters using the latest information available. The Company 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, the Company accrues the best estimate within the range. If no amount within the range is a better estimate than any other amount, the Company accrues the minimum amount within the range. If an unfavorable outcome is probable but the amount of the loss cannot be reasonably estimated, the Company 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, the Company discloses the nature and estimate of the possible loss of the litigation. The Company 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. Based on current expectations, such matters, both individually and in the aggregate, are not expected to have a material adverse effect on the liquidity, results of operations, business or financial condition of the Company.

	In August 2014, the Company issued 18.0 million shares of common stock, resulting in net proceeds to the Company of $223.4 million, which includes customary legal, accounting, and other expenses. The Company used the proceeds from this offering to acquire Fifth Third Center, a 698,000 square foot Class-A office tower located in the Charlotte, North Carolina central business district.
	In March 2014, the Company issued 8.7 million shares of common stock, resulting in net proceeds to the Company of $98.5 million, which includes customary legal, accounting, and other expenses.

STOCK-BASED COMPENSATION	'
	STOCK-BASED COMPENSATION
	The Company has several types of stock-based compensation - stock options, restricted stock, and restricted stock units (“RSUs”) - which are described in note 13 of notes to consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2013. The expense related to a portion of the stock-based compensation awards is fixed. The expense related to other stock-based compensation awards fluctuates from period to period dependent, in part, on the Company's stock price and stock performance relative to its peers. The Company recorded stock-based compensation expense, net of forfeitures, of $2.3 million for each of the three months ended September 30, 2014 and 2013 and $7.2 million and $5.9 million for the nine months ended September 30, 2014 and 2013, respectively.
	The Company maintains the 2005 Restricted Stock Unit Plan (the “RSU Plan”), which is described in note 13 of notes to consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2013. Under the RSU Plan, the Company made restricted stock grants in 2014 of 137,591 shares to key employees, which vest ratably over a three-year period. In addition, the Company awarded two types of RSUs to key employees based on the following metrics: (1) Total Stockholder Return of the Company, as defined in the RSU Plan, as compared to the companies in the SNL US REIT Office index (“SNL RSUs”), and (2) the ratio of cumulative funds from operations per share to targeted cumulative funds from operations per share (“FFO RSUs”) as defined in the RSU Plan. The performance period for both awards is January 1, 2014 to December 31, 2016, and the targeted units awarded of SNL RSUs and FFO RSUs is 108,751 and 56,405, respectively. The ultimate payout of these awards can range from 0% to 200% of the targeted number of units depending on the achievement of the market and performance metrics described above. Both of these RSUs cliff vest on January 30, 2017 and are dependent upon the attainment of required service, market and performance criteria. The number of RSUs vesting will be determined at that date, and the payout per unit will be equal to the average closing price on each trading day during the 30-day period ending on December 31, 2016. The SNL RSUs are valued using a quarterly Monte Carlo valuation and are expensed over the vesting period. The FFO RSUs are expensed over the vesting period using the fair market value of the Company's stock at the reporting date multiplied by the anticipated number of units to be paid based on the current estimate of what the ratio is expected to be upon vesting.

EARNINGS PER SHARE	'
	EARNINGS PER SHARE
	Net income (loss) per share-basic is calculated as net income (loss) available to common stockholders divided by the weighted average number of common shares outstanding during the period, including nonvested restricted stock which has nonforfeitable dividend rights. Net income (loss) per share-diluted is calculated as net income (loss) available to common stockholders divided by the diluted weighted average number of common shares outstanding during the period. Diluted weighted average number of common shares uses the same weighted average share number as in the basic calculation and adds the potential dilution, if any, that would occur if stock options (or any other contracts to issue common stock) were exercised and resulted in additional common shares outstanding, calculated using the treasury stock method. The numerator is reduced for the effect of preferred dividends in both the basic and diluted net income (loss) per share calculations. Weighted average shares-basic and diluted for the three and nine months ended September 30, 2014 and 2013, respectively, are as follows (in thousands):
		Three Months Ended September 30,		Nine Months Ended September 30,
		2014	2013	2014	2013
	Weighted average shares — basic	209,839	163,426	200,073	128,953
	Dilutive potential common shares — stock options	272	177	252	168
	Weighted average shares — diluted	210,111	163,603	200,325	129,121
	Weighted average anti-dilutive stock options	2,200	2,784	2,200	2,908
	Stock options are dilutive when the average market price of the Company's stock during the period exceeds the option exercise price. In periods where the Company is in a net loss position, the dilutive effect of stock options is not included in the diluted weighted average shares total.
	Anti-dilutive stock options represent stock options which are outstanding but which are not exercisable during the period because the exercise price exceeded the average market value of the Company's stock. These anti-dilutive stock options are not included in the current calculation of dilutive weighted average shares, but could be dilutive in the future.

	REPORTABLE SEGMENTS
	The Company has four reportable segments: Office, Retail, Land, and Other. These reportable segments represent an aggregation of operating segments reported to the chief operating decision maker based on similar economic characteristics that include the type of product and the nature of service. Each segment includes both consolidated operations and joint ventures, where applicable. The Office and Retail segments show the results for that product type. The Land segment includes results of operations for certain land holdings and single-family residential communities. The Other segment includes:
	•	fee income and related expenses for third party owned properties and joint venture properties for which the Company performs management, development and leasing services;
	•	compensation for corporate employees;
	•	general corporate overhead costs, interest expense for consolidated and unconsolidated entities;
	•	income attributable to noncontrolling interests;
	•	income taxes;
	•	depreciation; and
	•	preferred dividends.
	Company management evaluates the performance of its reportable segments in part based on funds from operations available to common stockholders (“FFO”). FFO is a supplemental operating performance measure used in the real estate industry. The Company calculated FFO using the National Association of Real Estate Investment Trusts’ (“NAREIT”) definition of FFO, which is net income (loss) available to common stockholders (computed in accordance with GAAP), excluding extraordinary items, cumulative effect of change in accounting principle and gains on sale or impairment losses on depreciable property, plus depreciation and amortization of real estate assets, and after adjustments for unconsolidated partnerships and joint ventures to reflect FFO on the same basis.
	FFO is used by industry analysts, investors and the Company as a supplemental measure of a REIT’s operating performance. Historical cost accounting for real estate assets implicitly assumes that the value of real estate assets diminishes predictably over time. Since real estate values instead have historically risen or fallen with market conditions, many industry investors and analysts have considered presentation of operating results for real estate companies that use historical cost accounting to be insufficient by themselves. Thus, NAREIT created FFO as a supplemental measure of a REIT’s operating performance that excludes historical cost depreciation, among other items, from GAAP net income. Management believes the use of FFO, combined with the required primary GAAP presentations, has been fundamentally beneficial, improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful. Company management evaluates operating performance in part based on FFO. Additionally, the Company uses FFO, along with other measures, to assess performance in connection with evaluating and granting incentive compensation to its officers and other key employees.
	Segment net income, the balance of the Company’s investment in joint ventures and the amount of capital expenditures are not presented in the following tables. Management does not utilize these measures when analyzing its segments or when making resource allocation decisions, and therefore this information is not provided. FFO is reconciled to net income (loss) on a total Company basis (in thousands):

When reviewing the results of operations for the Company, management analyzes the following revenue and income items net of their related costs:
•	Rental property operations;
•	Land sales; and
•	Gains on sales of investment properties.
These amounts are shown in the segment tables above in the same “net” manner as shown to management. In addition, management reviews the operations of discontinued operations and its share of the operations of its joint ventures in the same manner as the operations of its wholly-owned properties included in the continuing operations. Therefore, the information in the tables above includes the operations of discontinued operations and its share of joint ventures in the same categories as the operations of the properties included in continuing operations. Certain adjustments are required to reconcile the above segment information to the Company’s consolidated revenues.

	In April 2014, the FASB issued new guidance related to the presentation of discontinued operations, which changed the accounting criteria for discontinued operations. See footnote 1 for further information. The new guidance applies to assets that are sold or meet the criteria for held for sale after the date of adoption. The Company adopted the new standard in 2014. As a result, two of the Company’s properties that became held for sale in the third quarter of 2014 (777 Main and Mahan Village) that under the previous guidance would have been considered discontinued operations are not considered discontinued operations under the new guidance.
