Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	Summary of Significant Accounting Policies
	Basis of Presentation and Principles of Consolidation
	The accompanying financial statements are prepared following U.S. generally accepted accounting principles ("GAAP") and the requirements of the Securities and Exchange Commission ("SEC").
	The consolidated financial statements include the accounts of Parkway Properties, Inc. ("Parkway" or "the Company"), its wholly-owned subsidiaries and joint ventures in which the Company has a controlling interest.  The other partners' equity interests in the consolidated joint ventures are reflected as noncontrolling interests in the consolidated financial statements.  Parkway also consolidates subsidiaries where the entity is a variable interest entity ("VIE") and Parkway is the primary beneficiary and has the power to direct the activities of the VIE and has the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE.  At December 31, 2012 and 2011, Parkway did not have any VIEs that required consolidation.  All significant intercompany transactions and accounts have been eliminated in the accompanying financial statements.
	The Company also consolidates certain joint ventures where it exercises significant control over major operating and management decisions, or where the Company is the sole general partner and the limited partners do not possess kick-out rights or other substantive participating rights.  The equity method of accounting is used for those joint ventures that do not meet the criteria for consolidation and where Parkway exercises significant influence but does not control these joint ventures.
	As of September 30, 2013, the results of operations for four of the Company's properties were classified as discontinued operations due to the disposal of these properties during the nine months ended September 30, 2013. The results of operations for these four properties were not previously classified as discontinued operations for the year ended December 31, 2012 as the four properties did not meet the criteria for held for sale accounting as of December 31, 2012.
	As a result of these dispositions, the consolidated statements of operations and comprehensive loss and consolidated statements of cash flows have been revised to reclassify the results of operations for these properties from continuing operations to discontinued operations. Additionally, Note A (Revenue Recognition), Note G, Note M, and Note N have been revised to reflect the reclassification to discontinued operations.
	Business
	The Company's operations are exclusively in the real estate industry, principally the operation, leasing, acquisition and ownership of office buildings.
	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, the 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.  Although the Company believes the assumptions and estimates made are reasonable and appropriate, as discussed in the applicable sections throughout these consolidated 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 the Company's future operating results.  The Company's most significant estimates relate to impairments on real estate and other assets and purchase price allocations.
	Real Estate Properties
	Real estate properties are carried at cost less accumulated depreciation.  Cost includes the carrying amount of the Company's investment plus any additional consideration paid, liabilities assumed, and improvements made subsequent to acquisition. Depreciation of buildings and building improvements is computed using the straight-line method over the estimated useful lives of the assets.  Depreciation of tenant improvements, including personal property, is computed using the straight-line method over the lesser of useful life or the term of the lease involved.  Maintenance and repair expenses are charged to expense as incurred.
	Balances of major classes of depreciable assets (in thousands) and their respective estimated useful lives are:
			31-Dec			31-Dec
	Asset Category	Estimated Useful Life	2012			2011
	Land	Non-depreciable	$	159,039		$	116,598
	Buildings and garages	40 years	1,369,493			801,619
	Building improvements	7 to 40 years	65,328			53,909
	Tenant improvements	Lesser of useful life or term of lease	168,706			111,934

	Depreciation expense, including amounts recorded in discontinued operations, related to these assets of $50.7 million, $76.5 million, and $67.4 million was recognized in 2012, 2011 and 2010, respectively.
	The Company evaluates its real estate assets upon occurrence of significant adverse changes in its operations to assess whether any impairment indicators are present that affect the recovery of the carrying amount.  The carrying amount includes the net book value of tangible and intangible assets and liabilities.  Real estate assets are classified as held for sale or held and used.  Parkway records assets held for sale at the lower of carrying amount or fair value less cost to sell.  With respect to assets classified as held and used, Parkway recognizes an impairment loss if the carrying amount is not recoverable and exceeds the sum of undiscounted future cash flows expected to result from the use and eventual disposition of the asset.  The cash flow and fair value estimates are based on assumptions about employing the asset for its remaining useful life.  Factors considered in projecting future cash flows include, but are not limited to:  existing leases, future leasing and terminations, market rental rates, capital improvements, tenant improvements, leasing commissions, inflation and other known variables.  This market information is considered a Level 3 input as defined by Accounting Standards Certification ("ASC") 820, "Fair Value Measurements and Disclosures," ("ASC 820").  Upon impairment, Parkway recognizes an impairment loss to reduce the carrying value of the real estate asset to the estimate of its fair value.  During the year ended December 31, 2012, the impairment loss of $5.7 million related to an asset included in continuing operations and $3.5 million related to discontinued operations.
	The Company recognizes gains and losses from sales of real estate upon the realization at closing of the transfer of rights of ownership to the purchaser, receipt from the purchaser of an adequate cash down payment and adequate continuing investment by the purchaser.
	The Company classifies certain assets as held for sale based on management having the authority and intent of entering into commitments for sale transactions to close in the next twelve months.  The Company considers an office property as held for sale once it has executed a contract for sale, allowed the buyer to complete its due diligence review and received a substantial non-refundable deposit.  Until a buyer has completed its due diligence review of the asset, necessary approvals have been received and substantive conditions to the buyer's obligation to perform have been satisfied, the Company does not consider a sale to be probable.  When the Company identifies an asset as held for sale, it estimates the net realizable value of such asset and discontinues recording depreciation on the asset.  The Company records assets held for sale at the lower of carrying amount or fair value less cost to sell.
	Land available for sale, which consists of 12 acres of land in New Orleans, Louisiana, is carried at cost and is subject to evaluation for impairment.
	Purchase Price Allocation
	Parkway allocates the purchase price of real estate to tangible and intangible assets and liabilities based on fair values.  Tangible assets consist of land, building, garage, building improvements and tenant improvements.  Intangible assets and liabilities consist of the value of above and below market leases, lease costs, the value of in-place leases, customer relationships and any value attributable to above or below market debt assumed with the acquisition.
	The Company may engage independent third-party appraisers to perform the valuations used to determine the fair value of these identifiable tangible and intangible assets.  These valuations and appraisals use commonly employed valuation techniques, such as discounted cash flow analyses. Factors considered in these analyses include an estimate of carrying costs during hypothetical expected lease-up periods considering current market conditions and costs to execute similar leases. Parkway also considers information obtained about each property as a result of its pre-acquisition due diligence, marketing and leasing activities in estimating the fair value of the tangible and intangible assets acquired. In estimating carrying costs, the Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods depending on specific local market conditions and depending on the type of property acquired. Additionally, Parkway estimates costs to execute similar leases including leasing commissions, legal and other related expenses to the extent that such costs are not already incurred in connection with a new lease origination as part of the transaction.
	The fair value of above or below market in-place lease values is the present value of the difference between the contractual amount to be paid pursuant to the in-place lease and the estimated current market lease rate expected over the remaining non-cancelable life of the lease.  The capitalized above market lease values are amortized as a reduction of rental income over the remaining term of the respective leases. The capitalized below market lease values are amortized as an increase to rental income over the remaining term of the respective leases.  Total amortization for above and below market leases, excluding amounts classified as discontinued operations, was a net reduction of rental income of $5.1 million and $3.0 million for the years ended December 31, 2012 and 2011, respectively, and a net increase of rental income of $163,000 for the year ended December 31, 2010.
	As of December 31, 2012, amortization of above and below market leases is projected as a net decrease to rental income as follows for the next five years (in thousands):
		Amount
	2013	$	(2,986	)
	2014	(1,057		)
	2015	(439		)
	2016	(409		)
	2017	(674		)
	The fair value of customer relationships represents the quantifiable benefits related to developing a relationship with the current customer.  Examples of these benefits would be growth prospects for developing new business with the existing customer, the ability to attract similar customers to the building, the customer's credit quality and expectations of lease renewals (including those existing under the terms of the lease agreement), among other factors.  Management believes that there would typically be little value associated with customer relationships that is in excess of the value of the in-place lease and their typical renewal rates.  Any value assigned to customer relationships is amortized over the remaining terms of the respective leases plus any expected renewal periods as a lease cost amortization expense.  Currently, the Company has no value assigned to customer relationships.
	The fair value of at market in-place leases is the present value associated with re-leasing the in-place lease as if the property was vacant.  Factors to be considered include estimates of carrying costs during hypothetical expected lease-up periods considering current market conditions and costs to execute similar leases.  In estimating carrying costs, the Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods.  The value of at market in-place leases is amortized as a lease cost amortization expense over the expected life of the lease.  Total amortization expense for the value of in-place leases, excluding amounts classified as discontinued operations, was $15.9 million, $12.3 million, and $5.2 million for the years ended December 31, 2012, 2011 and 2010, respectively.
	As of December 31, 2012, amortization expense for the value of in-place leases is projected as follows for the next five years (in thousands):
		Amount
	2013	$	20,898
	2014	16,201
	2015	13,656
	2016	11,530
	2017	7,850
	A separate component of the fair value of in-place leases is identified for the lease costs.  The fair value of lease costs represents the estimated commissions and legal fees paid in connection with the current leases in place.  Lease costs are amortized over the non-cancelable terms of the respective leases as lease cost amortization expense.
	In no event does the amortization period for intangible assets exceed the remaining depreciable life of the building. Should a customer terminate its lease, the unamortized portion of the tenant improvement, in-place lease value, lease cost and customer relationship intangibles would be charged to expense.  Additionally, the unamortized portion of above market in-place leases would be recorded as a reduction to rental income and the below market in-place lease value would be recorded as an increase to rental income.
	Goodwill
	During 2011, the Company early adopted Accounting Standards Updated ("ASU") 2011-8, which allows an entity to first assess the qualitative factors in determining when a two-step quantitative goodwill impairment test is necessary.  If an entity determines, based on qualitative factors, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the entity would then be required to calculate the fair value of the reporting entity.  The Company acquired goodwill in 2011 when it closed on the agreement with Eola Capital, LLC and related entities ("Eola") in which Eola contributed its property management company to Parkway.  During 2012, the company evaluated certain qualitative factors and determined that it was necessary to apply the two-step quantitative impairment test.  During this process the Company determined that the management contracts related to its goodwill were impaired due to the fair value of these management contracts being estimated at $19.0 million as compared to the carrying amount of $46.1 million.  Next, the Company computed the fair value of the assets and liabilities associated with management contracts and determined that the associated goodwill was impaired.  During the year ended December 31, 2012, the Company recorded a $42.0 million non-cash impairment loss, net of deferred tax liability, associated with the Company's investment in management contracts and goodwill.  The Company's strategy related to the third-party management business has changed since the acquisition of these contracts.  When they were acquired, the Company's strategy was to grow the third-party business and continue to add management contracts in Parkway's various markets.  While the Company still views the cash flow from this business as positive and the additional management contracts gives Parkway scale and critical mass in some of its key markets, the Company is no longer actively seeking to grow this portion of the business.  Given this change in strategy, the Company determined that its management contracts and associated goodwill was impaired and recorded a $42.0 million non-cash impairment charge, net of deferred tax liability, during the fourth quarter of 2012.
	Allowance for Doubtful Accounts
	Accounts receivable are reduced by an allowance for amounts that the Company estimates to be uncollectible.  The receivable balance is comprised primarily of rent and expense reimbursement income due from the customers.  Management evaluates the adequacy of the allowance for doubtful accounts considering such factors as the credit quality of the customers, delinquency of payment, historical trends and current economic conditions.  The Company provides an allowance for doubtful accounts for customer balances that are over 90 days past due and for specific customer receivables for which collection is considered doubtful.
	Cash Equivalents
	The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.
	Noncontrolling Interest
	Noncontrolling Interest – Real Estate Partnerships
	At December 31, 2012 and 2011, the Company had an interest in one and two joint ventures, respectively, whose operations are included in its consolidated financial statements.  These joint ventures were originally structured such that the Company would own a 25% and 30% interest in Parkway Properties Office Fund, LP ("Fund I") and Parkway Properties Office Fund II, LP ("Fund II"), respectively.
	Parkway serves as the general partner of Fund II and provides asset management, property management, leasing and construction management services to the fund, for which it is paid market-based fees.  Cash is distributed from Fund II pro rata to each partner until a 9% annual cumulative preferred return is received and invested capital is returned.  Thereafter, 56% will be distributed to Parkway's partner in Fund II, Teacher Retirement System of Texas ("TRST") and 44% to Parkway.  The term of Fund II is seven years from the date the fund was fully invested, or until February 2019, with provisions to extend the term for two additional one-year periods at the Company's discretion.
	The Company previously entered into an agreement to sell its interest in 13 office properties totaling 2.7 million square feet owned by Parkway Properties Office Fund, L.P. ("Fund I") to its existing partner in the fund for a gross sales price of $344.3 million.  As of July 1, 2012, the Company had completed the sale of all 13 Fund I assets.
	Noncontrolling interest in real estate partnerships represents the other partners' proportionate share of equity in the partnerships discussed above at December 31, 2012 and 2011.  Income is allocated to noncontrolling interest based on the weighted average percentage ownership during the year.
	Revenue Recognition
	Revenue from real estate rentals is recognized on a straight-line basis over the terms of the respective leases.  The cumulative difference between lease revenue recognized under this method and contractual lease payment terms is recorded as straight-line rent receivable on the accompanying balance sheets.  The straight-line rent adjustment increased revenue by $15.3 million, $6.1 million and $1.2 million in 2012, 2011 and 2010, respectively.
	When the Company is the owner of the customer improvements, the leased space is ready for its intended use when the customer improvements are substantially completed. In limited instances, when the customer is the owner of the customer improvements, straight-line rent is recognized when the customer takes possession of the unimproved space.
The leases also typically provide for customer reimbursement of a portion of common area maintenance and other operating expenses.  Property operating cost recoveries from customers ("expense reimbursements") are recognized as revenue in the period in which the expenses are incurred.  The computation of expense reimbursements is dependent on the provisions of individual customer leases.  Most customers make monthly fixed payments of estimated expense reimbursements.  The Company makes adjustments, positive or negative, to expense reimbursement income quarterly to adjust the recorded amounts to the Company's best estimate of the final property operating costs based on the most recent quarterly budget.  After the end of the calendar year, the Company computes each customer's final expense reimbursements and issues a bill or credit for the difference between the actual amount and the amounts billed monthly during the year.
Management company income represents market-based fees earned from providing management, construction, leasing, brokerage and acquisition services to third parties. Management fee income is computed and recorded monthly in accordance with the terms set forth in the stand alone management service agreements. Leasing and brokerage commissions, as well as salary and administrative fees, are recognized pursuant to the terms of the stand-alone agreements at the time underlying leases are signed, which is the point at which the earnings process is complete and collection of the fees is reasonably assured. Fees relating to the purchase or sale of property are recognized when the earnings process is complete and collection of the fees is reasonably assured, which usually occurs at closing. All fees on Company-owned properties and consolidated joint ventures are eliminated in consolidation.  The Company recognizes its share of fees earned from unconsolidated joint ventures in management company income.
Amortization
Debt origination costs are deferred and amortized using a method that approximates the effective interest method over the term of the loan.  Leasing costs are deferred and amortized using the straight-line method over the term of the respective lease.
Early Extinguishment of Debt
When outstanding debt is extinguished, the Company records any prepayment premium and unamortized loan costs to interest expense.
Derivative Financial Instruments
The Company recognizes all derivative instruments on the balance sheet at their fair value.  Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income (loss), depending on whether a derivative is designated as part of a hedge transaction and, if it is, the type of hedge transaction.  The ineffective portion of the hedge, if any, is immediately recognized in earnings.
Share-Based and Long-Term Compensation
Effective May 1, 2010, the stockholders of the Company approved Parkway's 2010 Omnibus Equity Incentive Plan (the "2010 Equity Plan") that authorized the grant of up to 600,000 equity based awards to employees and directors of the Company.   The 2010 Equity Plan replaced the Company's 2003 Equity Incentive Plan and the 2001 Non-Employee Directors Equity Compensation Plan.  At present, it is Parkway's intention to grant restricted shares and/or deferred incentive share units instead of stock options although the 2010 Equity Plan authorizes various forms of incentive awards, including options.  The 2010 Equity Plan has a ten-year term.
On May 12, 2011, the Board of Directors approved Parkway's 2011 Employee Inducement Award Plan that authorized the grant of up to 149,573 restricted shares and/or deferred incentive share units to employees and directors of the Company in connection with the combination with Eola.  The Plan shall continue in effect until the earlier of (a) its termination by the Board or (b) the date on which all of the shares of stock available for issuance under the Plan have been issued; provided that awards outstanding on that date shall survive in accordance with their terms.
Compensation expense, including estimated forfeitures, for service-based awards is recognized over the expected vesting period.  The total compensation expense for the long-term equity incentive awards is based upon the fair value of the shares on the grant date, adjusted for estimated forfeitures.  Time-based restricted shares and deferred incentive share units are valued based on the New York Stock Exchange closing market price of Parkway common shares (NYSE:  PKY) as of the date of grant.  The grant date fair value for awards that are subject to market conditions is determined using a simulation pricing model developed to specifically accommodate the unique features of the awards.
Restricted shares and deferred incentive share units are forfeited if an employee leaves the Company before the vesting date, except in the case of the employee's death or permanent disability or upon termination following a change of control. Shares and/or units that are forfeited become available for future grant under the 2010 Equity Plan.
The Company also adopted a long-term cash incentive that was designed to reward significant outperformance over the three year period which began July 1, 2010.  The total compensation expense for the long-term cash incentive awards is based upon the estimated fair value of the award on the grant date and adjusted as necessary each reporting period.  The long-term cash incentive awards are accounted for as a liability-classified award on the Company's 2012 and 2011 consolidated balance sheets.  The grant date and quarterly fair value estimates for awards that are subject to a market condition are determined using a simulation pricing model developed to specifically accommodate the unique features of the awards.
Income Taxes
The Company elected to be taxed as a REIT under the Internal Revenue Code, commencing with its taxable year ended December 31, 1997.  To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement that it currently distribute at least 90% of its adjusted taxable income to its stockholders.  It is management's current intention to adhere to these requirements and maintain the Company's REIT status, and the Company was in compliance with all REIT requirements at December 31, 2012.  As a REIT, the Company generally will not be subject to corporate level federal income tax on taxable income it distributes currently to its stockholders.  If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years.  Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed taxable income. In addition, taxable income from non-REIT activities managed through TRSs is subject to federal, state and local income taxes.
Effective May 18, 2011, the Company acquired the Eola management company and contributed the entity into a taxable REIT subsidiary ("TRS") wholly-owned by the operating partnership.  In connection with the purchase of the Eola management company, the TRS recorded a deferred income tax liability of $14.8 million.  At December 31, 2012, the Company carried a deferred tax liability of $2.0 million, as compared to a balance of $14.3 million at December 31, 2011.  The balance was reduced during the fourth quarter of 2012 as a result of the reduction in the value of the Company's management contracts to $19.0 million.  The TRS pays income taxes at the federal and state level.
Net Loss Per Common Share
Basic earnings per share ("EPS") is computed by dividing loss attributable to common stockholders by the weighted-average number of common shares outstanding for the year.  In arriving at net loss attributable to common stockholders, preferred stock dividends are deducted.  Diluted EPS reflects the potential dilution that could occur if share equivalents such as employee stock options, restricted shares and deferred incentive share units were exercised or converted into common stock that then shared in the earnings of Parkway.
The computation of diluted EPS is as follows:
	Year Ended December 31
	2012			2011			2010
	(in thousands, except per share data)
Numerator:
Basic and diluted net loss
attributable to common stockholders	$	(51,249	)	$	(136,955	)	$	(8,943	)
Denominator:
Basic and diluted weighted average shares	31,542			21,497			21,421
Diluted net loss per share attributable to
common stockholders	$	(1.62	)	$	(6.37	)	$	(0.42	)
The computation of diluted EPS for 2012, 2011 and 2010 did not include the effect of employee stock options, deferred incentive share units and restricted shares because their inclusion would have been anti-dilutive.
Reclassifications
Certain reclassifications have been made in the 2011 and 2010 consolidated financial statements to conform to the 2012 classifications with no impact on previously reported net income or equity.
Subsequent Events
The Company has evaluated all subsequent events through the issuance date of the consolidated financial statements.
Recent Accounting Pronouncements
In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-4, "Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS", which change the wording used to describe the requirements in U.S. GAAP for measuring fair value, changes certain fair value measurement principles and enhances disclosure requirements for fair value measurements.  The FASB does not intend for ASU 2011-4to result in a change in the application of the requirements in ASC 820.  The requirements of ASU 2011-4 will be effective prospectively for interim and annual periods beginning after December 15, 2011.  At March 31, 2012, the Company had implemented ASU 2011-4.
In June 2011, the FASB issued ASU 2011-5, "Comprehensive Income", which modifies reporting requirements for comprehensive income in order to increase the prominence of items reported in other comprehensive income in the financial statements.  ASU 2011-5 requires presentation of either a single continuous statement of comprehensive income or two separate, but consecutive statements in which the first statement presents net income and its components followed by a second statement that presents total other comprehensive income, the components of other comprehensive income, and total comprehensive income. The requirements of ASU 2011-5 will be effective for interim and annual periods beginning after December 15, 2011.  At March 31, 2012, the Company had implemented ASU 2011-5.

	In connection with the previous sale of One Park Ten, the Company had seller-financed a $1.5 million note receivable that bore interest at 7.3% per annum on an interest-only basis through maturity in June 2012.  On April 2, 2012, the borrower repaid the note receivable and all accrued interest in full.
	On April 10, 2012, the Company transferred its rights, title and interest in the B participation piece (the "B piece") of a first mortgage secured by an 844,000 square foot office building in Dallas, Texas known as 2100 Ross.  The B piece was purchased at an original cost of $6.9 million in November 2007.  The B piece was originated by Wachovia Bank, N.A., a Wells Fargo Company, and had a face value of $10.0 million, a stated coupon rate of 6.1% and a scheduled maturity in May 2012.  During 2011, the Company recorded a non-cash impairment loss on the mortgage loan in the amount of $9.2 million, thereby reducing its investment in the mortgage loan to Zero.  Under the terms of the transfer, the Company is entitled to certain payments if the transferee is successful in obtaining ownership of 2100 Ross.  During the third quarter of 2012, the transferee successfully obtained ownership of 2100 Ross and as a result the Company received a $500,000 payment, which is classified as recovery of losses on a mortgage loan receivable on the Company's Consolidated Statements of Operations and Comprehensive Income.

	Management Contracts
	During the second quarter of 2011, as part of the Company's combination with Eola, Parkway purchased the management contracts associated with Eola's property management business.  At the purchase date, the contracts were valued by an independent appraiser at $51.8 million.  The value of the management contracts is based on the sum of the present value of future cash flows attributable to the management contracts, in addition to the value of tax savings as a result of the amortization of intangible assets.
	During 2012, the Company evaluated certain qualitative factors and determined that it was necessary to apply the two-step quantitative impairment test under ASU 2011-8.  During this process the Company determined that the management contracts were impaired due to the fair value of the management contracts being estimated at $19.0 million as compared to the carrying amount of $46.1 million.  As a result, the Company recorded a $42.0 million non-cash impairment loss, net of deferred tax liability, associated with the Company's investment in management contracts and goodwill.  The Company's strategy related to the third-party management business has changed since the acquisition of these contracts.  When the contracts were acquired, the Company's strategy was to grow the third-party business and continue to add management contracts in Parkway's various markets.  While the Company still views the cash flow from this business as positive and the additional management contracts gives Parkway scale and critical mass in some of its key markets, the Company is no longer actively seeking to grow this portion of the business.  Given this change in strategy and as a result of the decrease in cash flow from the management company due to management contracts terminated during 2012, the Company determined that its management contracts and associated goodwill was impaired and recorded a $42.0 million non-cash impairment charge, net of deferred tax liability, during the fourth quarter of 2012.
	At December 31, 2012, the Company carried a deferred tax liability of $2.0 million.  The balance was reduced during the fourth quarter of 2012 from the initial $14.8 million as a result of the reduction in the value of the Company's management contracts to $19.0 million, which will be amortized over their remaining useful life of 2.7 years.

On February 10, 2012, Fund II entered into an interest rate swap with the lender of the loan secured by Hayden Ferry II in Phoenix, Arizona, for a $50 million notional amount that fixes LIBOR at 1.5% through January 25, 2018, which when combined with the applicable spread ranging from 250 to 350 basis points equates to a total interest rate ranging from 4.0% to 5.0% over the term of the loan. The Company designated the swap as a cash flow hedge of the variable interest payments associated with the mortgage loan.
On May 31, 2012, in connection with the sale of the Pinnacle at Jackson Place ("the Pinnacle"), the buyer assumed the interest rate swap, which had a notional amount of $23.5 million and fixed the interest rate on a portion of the debt secured by the Pinnacle at 5.8%.
On September 28, 2012, the Company executed two floating-to-fixed interest rate swaps for a notional amount totaling $125.0 million, associated with its term loan that fixes LIBOR at 0.7% for five years, which resulted in an initial all-in interest rate of 2.2%. The interest rate swaps were effective October 1, 2012 and mature September 28, 2017.
On December 31, 2012, in connection with the purchase of NASCAR Plaza in Charlotte, North Carolina, the Company assumed an interest rate swap for a $30.0 million notional amount that fixes LIBOR at 2.3% through February 1, 2016.
The Company designated these swaps as cash flow hedges of the variable interest payments associated with the mortgage loans.

	Fund II, a $750.0 million discretionary fund, was formed on May 14, 2008 and was fully invested at February 10, 2012.  Fund II was structured such that TRST as a 70% investor and Parkway as a 30% investor in the fund, with an original target capital structure of approximately $375.0 million of equity capital and $375.0 million of non-recourse, fixed-rate first mortgage debt. Fund II acquired 13 properties totaling 4.2 million square feet in Atlanta, Charlotte, Phoenix, Jacksonville, Orlando, Tampa and Philadelphia.  In August 2012, Fund II increased its investment capacity by $20.0 million to purchase Hayden Ferry III, IV and V, a 2,500 space parking garage, a 21,000 square foot office property and a vacant parcel of development land, all adjacent to Hayden Ferry I and Hayden Ferry II in Phoenix.
	Parkway serves as the general partner of Fund II and provides asset management, property management, leasing and construction management services to the fund, for which it is paid market-based fees.  Cash is distributed by Fund II pro rata to each partner until a 9% annual cumulative preferred return is received and invested capital is returned.  Thereafter, 56% will be distributed to TRST and 44% to Parkway.  The term of Fund II is seven years from the date the fund was fully invested, or until February 2019, with provisions to extend the term for two additional one-year periods at the Company's discretion.
	The Company entered into an agreement to sell 13 office properties, totaling 2.7 million square feet, owned by Fund I to its existing partner in the fund for a gross sales price of $344.3 million, of which $97.4 million was Parkway's share.  As of December 31, 2011, the Company had completed the sale of nine of these 13 assets.  As of July 1, 2012, the Company had completed the sale of the remaining four Fund I assets.  The Company received approximately $14.2 million in net proceeds from the sales of the Fund I assets, and the proceeds were used to reduce amounts outstanding under its credit facilities.  Upon sale, the buyer assumed a total of $292.0 million in mortgage loans, of which $82.4 million was Parkway's share.

	During 2012, the Company completed its previously disclosed dispositions as part of its strategic objective of becoming a leading owner of high-quality office assets in higher growth markets in the Sunbelt region of the United States.  As previously disclosed, the Company entered into an agreement to sell its interest in 13 office properties totaling 2.7 million square feet owned by Parkway Properties Office Fund, L.P. ("Fund I") to its existing partner in the fund for a gross sales price of $344.3 million.  As of December 31, 2011, Parkway had completed the sale of 9 of these 13 assets.  During the year ended December 31, 2012, the Company completed the sale of the remaining four Fund I assets totaling 770,000 square feet.  Accordingly, income from all Fund I properties has been classified as discontinued operations for all current and prior periods.  These Fund I assets were secured by a total of $292.0 million in mortgage loans, of which $82.4 million was Parkway's share, with a weighted average interest rate of 5.6% that were assumed by the buyer upon closing.  Parkway received net proceeds from the sales of the Fund I assets of $14.2 million, which were used to reduce amounts outstanding under the Company's credit facilities.
	Additionally, during the year ended December 31, 2012, the Company completed the sale of the 15 properties included in its strategic sale of a portfolio of non-core assets, for a gross sales price of $147.7 million and generating net proceeds to Parkway of approximately $94.3 million, with the buyer assuming $41.7 million in mortgage loans upon sale, of which $31.9 million was Parkway's share.  The 15 assets that were sold include five assets in Richmond, four assets in Memphis, and six assets in Jackson. Income from these non-core assets has been classified as discontinued operations for all current and prior periods.

("Fund II") for a gross sales price of $168.8 million.  Parkway received approximately $14.8 million in net proceeds from these sales, which were used to reduce amounts outstanding under the Company's revolving credit facility and to fund subsequent acquisitions.  In connection with the sale of 111 East Wacker, the buyer assumed a $147.9 million mortgage loan upon sale.  Income from 111 East Wacker, the Wink building, Sugar Grove and Falls Pointe has been classified as discontinued operations for all current and prior periods.
	At December 31, 2012, assets that were reported in discontinued operations and were sold in 2013 represented four properties: Atrium at Stoneridge, totaling 108,000 square feet and located in Columbia, South Carolina, that was sold on March 20, 2013; Waterstone and Meridian, totaling 190,000 square feet and located in Atlanta, Georgia, that were sold on July 10, 2013; and Bank of America Plaza, a 436,000 square foot office property located in Nashville, Tennessee that was sold on July 17, 2013.

Income Tax Disclosure [Abstract]	'
Income Taxes	'
	Income Taxes
	The Company elected to be taxed as a REIT under the Internal Revenue Code, commencing with its taxable year ended December 31, 1997.  To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement that it currently distribute at least 90% of its adjusted taxable income to its stockholders.  It is management's current intention to adhere to these requirements and maintain the Company's REIT status, and the Company was in compliance with all REIT requirements at December 31, 2012.  As a REIT, the Company generally will not be subject to corporate level federal income tax on taxable income it distributes currently to its stockholders.  If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years.  Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed taxable income. In addition, taxable income from non-REIT activities managed through TRSs is subject to federal, state and local income taxes.
	In January 1998, the Company completed its reorganization into an UPREIT structure under which substantially all of the Company's real estate assets are owned by an operating partnership, Parkway Properties LP.  Presently, substantially all interests in the Operating Partnership are owned by the Company and a wholly-owned subsidiary.  At December 31, 2012, the Company had estimated net operating loss ("NOL") carry forwards for federal income tax purposes of $160.7 million which expire at various dates beginning in 2018 through 2032. The utilization of these NOLs can cause the Company to incur a small alternative minimum tax liability.
	The Company's income differs for income tax and financial reporting purposes principally because real estate owned has a different basis for tax and financial reporting purposes, producing different gains upon disposition and different amounts of annual depreciation.
	The following reconciles GAAP net loss to taxable income (loss) for the years ending December 31, 2012, 2011 and 2010 (in thousands):

	The Company has elected to treat certain consolidated subsidiaries as taxable REIT subsidiaries, which are tax paying entities for income tax purposes and are taxed separately from the Company.  Taxable REIT subsidiaries may participate in non-real estate related activities and/or perform non-customary services for tenants and are subject to federal and state income tax at regular corporate tax rates.  On May 18, 2011, in connection with the combination of the Eola management company, the Company contributed the management company to a TRS wholly owned by the operating partnership.
	In connection with the purchase accounting for the management company, the Company recorded an initial deferred tax liability of $14.8 million representing differences between the tax basis and GAAP basis of the acquired assets and liabilities (primarily related to the management company contracts) multiplied by the effective tax rate.  The Company was required to record these deferred tax liabilities as a result of the Management Company becoming a C corporation at the time it was acquired. The Company's net deferred tax liabilities as of December 31, 2012 and 2011 were $2.0 million and $14.3 million, respectively.
	The components of income tax expense (benefit) for the years ended December 31, 2012, 2011, and 2010 are as follows (in thousands):

	In addition to the tax expense (benefit) represented above, the Company incurred an additional tax benefit of $11.4 million associated with the non-cash impairment loss on management contracts and goodwill.  This additional tax benefit is classified as part of the impairment loss on management contracts and goodwill on the Company's Consolidated Statements of Operations and Comprehensive Loss. The income tax expense (benefit) for the years ended December 31, 2012, 2011, and 2010 is all from continuing operations.
	Consolidated income (loss) subject to tax consists of pretax income or loss of taxable REIT subsidiaries.  For the year ended December 31, 2012, the Company had consolidated losses subject to tax of $41.8 million and during the year ended December 31, 2011, the Company had consolidated income subject to tax of $12.5 million.  The reconciliation of income tax attributable to continuing operations computed at the U.S. statutory rate to income tax benefit is shown below (in thousands):

	Total income tax expense (benefit)	$	261		58.9	%		$	56			0.5	%
	The Company accounts for uncertainties in income tax law in accordance with FASB ASC Topic 740.  Under FASB ASC Topic 740, tax positions shall initially be recognized in the financial statements when it is more likely than not the position will be sustained upon examination by the tax authorities.  Such tax positions shall initially and subsequently be measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority assuming full knowledge of the position and relevant facts.  The Company believes that it has appropriate support for the income tax positions taken and to be taken on its tax returns and that its accruals for tax liabilities are adequate for all open tax years based on an assessment of many factors including past experience and interpretations of tax laws applied to the facts of each matter. Federal and state tax returns are open from 2008 and forward for the Company and open from 2011 and forward for the taxable REIT subsidiary formed as a result of the combination with Eola.

	Share-Based and Long-Term Compensation Plans
	Effective May 1, 2010, the stockholders of the Company approved Parkway's 2010 Omnibus Equity Incentive Plan (the "2010 Equity Plan") that authorized the grant of up to 600,000 equity based awards to employees and directors of the Company.   The 2010 Equity Plan has a ten-year term.
	Compensation expense, including estimated forfeitures, for service-based awards is recognized over the expected vesting period.  The total compensation expense for the long-term equity incentive awards is based upon the fair value of the shares on the grant date, adjusted for estimated forfeitures.  Time-based restricted shares and deferred incentive share units are valued based on the New York Stock Exchange closing market price of Parkway common shares (NYSE:  PKY) as of the date of grant.  The grant date fair value for awards that are subject to market conditions is determined using a simulation pricing model developed to specifically accommodate the unique features of the awards.
	Restricted shares and deferred incentive share units are forfeited if an employee leaves the Company before the vesting date except in the case of the employee's death or permanent disability or upon termination following a change of control. Shares and/or units that are forfeited become available for future grant under the 2010 Equity Plan.
	On February 14, 2012, 21,900 long-term equity incentive awards were granted to officers of the Company.  The long-term equity incentive awards were valued at $222,000 which equates to an average price per share of $10.15 and are time-based awards.  These shares are accounted for as equity-classified awards.
	The time-based awards will vest ratably over four years from the date the shares are granted.  The market condition awards are contingent on the Company meeting goals for compounded annual total return to stockholders ("TRTS") over the three year period beginning July 1, 2010.  The market condition goals are based upon (i) the Company's absolute compounded annual TRS; and (ii) the Company's absolute compounded annual TRTS relative to the compounded annual return of the MSCI US REIT ("RMS") Index calculated on a gross basis, as follows:
		Threshold		Target		Maximum
	Absolute Return Goal	10%		12%		14%
	Relative Return Goal	RMS + 100 bps		RMS + 200 bps		RMS + 300 bps
	With respect to the absolute return goal, 15% of the award is earned if the Company achieves threshold performance and a cumulative 60% is earned for target performance.  With respect to the relative return goal, 20% of the award is earned if the Company achieves threshold performance and a cumulative 55% is earned for target performance.  In each case, 100% of the award is earned if the Company achieves maximum performance or better. To the extent actually earned, the market condition awards will vest 50% on each of July 15, 2013 and 2014.
	The Company also adopted a long-term cash incentive that was designed to reward significant outperformance over the three year period beginning July 1, 2010.  The performance goals for actual payment under the long-term cash incentive will require the Company to (i) achieve an absolute compounded annual TRTS that exceeds 14% AND (ii) achieve an absolute compounded annual TRS that exceeds the compounded annual return of the RMS by at least 500 basis points.  Notwithstanding the above goals, in the event the Company achieves an absolute compounded annual TRTS that exceeds 19%, then the Company must achieve an absolute compounded annual TRTS that exceeds the compounded annual return of the RMS by at least 600 basis points.  The aggregate amount of the cash incentive earned would increase with corresponding increases in the absolute compounded annual TRTS achieved by the Company.  There will be a cap on the aggregate cash incentive earned in the amount of $7.1 million. Achievement of the maximum cash incentive would equate to an absolute compounded annual TRS that approximates 23%, provided that the absolute compounded annual TRS exceeds the compounded annual return of the RMS by at least 600 basis points.  The total compensation expense for the long-term cash incentive awards is based upon the estimated fair value of the award on the grant date and adjustment as necessary each reporting period.  The long-term cash incentive awards are accounted for as a liability-classified award on the Company's 2012 and 2011 consolidated balance sheets.  The grant date and quarterly fair value estimates for awards that are subject to a market condition are determined using a simulation pricing model developed to specifically accommodate the unique features of the awards.
	At December 31, 2012, a total of 281,233 shares of restricted stock have been granted to officers of the Company.  The shares are valued at $2.3 million, which equates to an average price per share of $8.34.  The value, including estimated forfeitures, of restricted shares that vest based on service conditions will be amortized to compensation expense ratably over the vesting period for each grant of stock.  At December 31, 2012, a total of 17,760 deferred incentive share units have been granted to employees of the Company.  The deferred incentive share units are valued at $455,000, which equates to an average price per share of $25.61, and the units vest four years from grant date.  Total compensation expense related to the restricted stock and deferred incentive units of $432,000, $1.3 million and $1.3 million was recognized in 2012, 2011 and 2010, respectively.  Total compensation expense related to nonvested awards not yet recognized was $1.1 million at December 31, 2012.  The weighted average period over which this expense is expected to be recognized is approximately 1.5 years.

The Company declared dividends of $2.00 per share for the Series D Preferred stock for each of the three years 2012, 2011 and 2010.
The Company's shares of Series D preferred stock are listed on the New York Stock Exchange and trade under the symbol "PKY PrD".
On May 3, 2012, the Company entered into a Securities Purchase Agreement (the "Purchase Agreement"), by and among the Company and TPG Pantera.  Pursuant to the terms of the Purchase Agreement on June 5, 2012, the Company issued to TPG Pantera 4.3 million shares, or approximately $48.4 million, of common stock and approximately 13.5 million shares, with an initial liquidation value of $151.6 million, of newly-created, non-voting Series E Cumulative Redeemable Convertible Preferred Stock, par value $0.001 per share (the "Series E Preferred Stock").  The Company received proceeds of approximately $200.0 million and incurred approximately $13.9 million, which were recorded as a reduction to proceeds received.  During the year ended December 31, 2012, the Company issued an additional 6,666 shares of Series E Preferred Stock and 11,733 shares of common stock to TPG Pantera in lieu of director's fees pursuant to the agreements entered into with TPG Pantera at the closing under the Purchase Agreement and paid approximately $5.0 million and $1.0 million in dividends on common stock and Series E Preferred Stock, respectively, to TPG Pantera.

	Fair Values of Financial Instruments
	FASB Accounting Standards Codification ("ASC") 820, "Fair Value Measurements and Disclosures" ("ASC 820"), defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 also provides guidance for using fair value to measure financial assets and liabilities.  The Codification requires disclosure of the level within the fair value hierarchy in which the fair value measurements fall, including measurements using quoted prices in active markets for identical assets or liabilities (Level 1), quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active (Level 2), and significant valuation assumptions that are not readily observable in the market (Level 3).

	The methods and assumptions used to estimate fair value for each class of financial asset or liability are discussed below:
	Cash and cash equivalents:  The carrying amounts for cash and cash equivalents approximate fair value.
	Mortgage notes payable:  The fair value of mortgage notes payable is estimated using discounted cash flow analysis, based on the Company's current incremental borrowing rates for similar types of borrowing arrangements.  This information is considered a Level 2 input as defined by ASC 820.
	Notes payable to banks:  The fair value of the Company's notes payable to banks is estimated by discounting expected cash flows at current market rates.  This information is considered a Level 2 input as defined by ASC 820.
	Interest rate swap agreements:  The fair value of the interest rate swaps is determined by estimating the expected cash flows over the life of the swap using the mid-market rate and price environment as of the last trading day of the reporting period.  This information is considered a Level 2 input as defined by ASC 820.

	Acquisitions
	On January 17, 2013, the Company purchased Tower Place 200, a 260,000 square foot office tower located in the Buckhead submarket of Atlanta, Georgia, for a gross purchase price of $56.3 million.  The purchase of Tower Place 200 was financed with borrowings on our unsecured credit facilities.
	On March 7, 2013, the Company purchased two office complexes totaling 1.0 million square feet located in the Deerwood submarket of Jacksonville, Florida (the "Deerwood Portfolio") for a gross purchase price of $130.0 million.  The purchase of these properties was financed with a mortgage loan secured by the properties in the aggregate amount of $84.5 million and borrowings under the Company's senior unsecured revolving credit facility. The mortgage loan has a maturity date of April 1, 2023 and a fixed interest rate of 3.9%.
	On March 25, 2013, the Company purchased its co-investor's 70% interest in three office properties totaling 788,000 square feet located in the Westshore submarket of Tampa, Florida ("Tampa Fund II Assets").  The Tampa Fund II Assets were owned by Parkway Properties Office Fund II, L.P. ("Fund II").  The Company's purchase price for its co-investor's 70% interest in the Tampa Fund II Assets was $97.5 million.  Simultaneously with closing, the Company assumed $40.7 million of existing mortgage indebtedness that is secured by the properties, which represents its co-investor's 70% share of the approximately $58.1 million of existing mortgage indebtedness.  The three office properties include Corporate Center IV at International Plaza, Cypress Center I, II and III, and The Pointe. The Tampa Fund II Assets' office properties and associated mortgage loans were previously included in the Company's consolidated balance sheets and statements of operations and comprehensive income (loss).  Therefore, the Company's purchase of its co-investor's share in these office properties will not impact the Company's overall financial position.
	On April 26, 2013, the Company entered into a purchase and sale agreement to acquire Lincoln Place, a 140,000 square foot office building located in the South Beach submarket of Miami, Florida.  Lincoln Place is comprised of 111,000 square feet of office space and 29,000 square feet of retail space on the ground floor, with a five-story garage adjacent to the property. The property is currently 100% leased to LNR Corporation through June 2021 with no renewal or early termination option. Parkway is under contract to acquire Lincoln Place in exchange for the assumption of the existing secured first mortgage, which has a current outstanding balance of approximately $49.6 million, a fixed interest rate of 5.9% and a maturity date of June 11, 2016, and the issuance of 900,000 shares of operating partnership units. Based on Parkway's closing stock price of $18.06 per share on November 1, 2013, the implied purchase price would be approximately $65.9 million.
	On June 3, 2013, the Company purchased an approximate 75% equity method interest in the US Airways Building, a 225,000 square foot office property located in the Tempe submarket of Phoenix, Arizona, for a purchase price of $41.8 million, which is accounted for as an unconsolidated joint venture on the Company's consolidated balance sheets at June 30, 2013.  At closing, an affiliate of the Company issued a $13.9 million mortgage loan to the buyer, a wholly owned subsidiary, and an affiliate of US Airways, which is secured by the building. The mortgage loan carries a fixed interest rate of 3.0% and matures in December 2016. This nine-story Class A office building is adjacent to Parkway's Hayden Ferry Lakeside and Tempe Gateway assets and shares a parking garage with Tempe Gateway.  The property is the headquarters for US Airways, which has leased 100% of the building through April 2024.  US Airways has a termination option on December 31, 2016 or December 31, 2021 with 12 months prior notice.  US Airways is also the owner of the remaining approximate 25% in the building.  The Company accounts for its investment in the US Airways Building under the equity method of accounting.

The Company received $40.8 million in net proceeds from the sale, which was used to reduce amounts outstanding under the Company's revolving credit facilities.
	Financing Activity
	On February 21, 2013, we obtained an $80.0 million first mortgage secured by Phoenix Tower, a 629,000 square foot office property located in the Greenway Plaza submarket of Houston, Texas.  The mortgage loan bears interest at a fixed rate of 3.9% and matures on March 1, 2023.  Payments of interest only are due on the loan for two years, after which the principal amount of the loan begins amortizing over a 25-year period until maturity.  The loan is pre-payable after March 1, 2015, but any such prepayment is subject to a yield maintenance premium.  The agreement governing the mortgage loan contains customary rights of the lender to accelerate the loan upon, among other things, a payment default or if certain representations and warranties made by the borrower are untrue.
	On March 7, 2013, simultaneously with the purchase of the Deerwood Portfolio, we obtained an $84.5 million first mortgage, which is secured by the office properties in the portfolio.  The mortgage bears interest at a fixed rate of 3.9% and matures on April 1, 2023.  Payments of interest only are due on the loan for three years, after which the principal amount of the loan begins amortizing over a 30-year period until maturity.  The loan is pre-payable after May 1, 2015, but any such prepayment is subject to a yield maintenance premium.  The agreement governing the mortgage contains customary rights of the lender to accelerate the loan upon, among other things, a payment default or if certain representations and warranties made by the borrower are untrue.
	On March 25, 2013, simultaneously with the purchase of our co-investor's interest of the Tampa Fund II Assets, we assumed $40.7 million of existing first mortgages that are secured by the properties, which represents our co-investor's 70% share of the approximately $58.1 million of the existing first mortgages.
	On March 25, 2013, we completed an underwritten public offering of 11.0 million shares of our common stock, plus an additional 1.65 million shares of our common stock issued and sold pursuant to the exercise of the underwriters' option to purchase additional shares in full, at the public offering price of $17.25 per share.  The net proceeds from the offering, after deducting the underwriting discount and offering expenses, were approximately $209.0 million.  We used the net proceeds of the stock offering to redeem in full all of our outstanding Series D preferred stock and will use remaining net proceeds to fund potential acquisition opportunities, to repay amounts outstanding from time to time under our senior unsecured revolving credit facility and/or for general corporate purposes.
	On April 25, 2013, we redeemed all of our outstanding Series D preferred stock using proceeds from our March 2013 underwritten public offering of common stock.  We paid $136.3 million to redeem the preferred shares and incurred a charge during the second quarter of approximately $6.6 million, which represents the difference between the costs associated with the issuances, including the price at which such shares were paid, and the redemption price.
	On May 31, 2013, we modified the existing $22.5 million first mortgage secured by Corporate Center Four at International Plaza ("Corporate Center Four"), a 250,000 square foot office property located in the Westshore submarket of Tampa, Florida. The modified first mortgage carries a principal balance of $36.0 million, a weighted average fixed interest rate of 4.6%, an initial 24-month interest only period and a maturity date of April 8, 2019. In conjunction with the modification, we executed a floating-to-fixed interest rate swap fixing the interest rate on the additional $13.5 million in loan proceeds at 3.3%.
	On June 12, 2013, we repaid two first mortgages totaling $55.0 million which were secured by Cypress Center, a 286,000 square foot office complex in Tampa, Florida, and NASCAR Plaza, a 394,000 square foot office property in Charlotte, North Carolina. The two mortgages had a weighted average interest rate of 3.6% and were scheduled to mature in 2016. We repaid the mortgage loans using proceeds from our $120.0 million unsecured term loan.
	On June 28, 2013, we modified the existing mortgage secured by Hayden Ferry II, a 299,000 square foot office property located in the Tempe submarket of Phoenix, Arizona.  The loan modification eliminates quarterly principal payments of $625,000.  As a result of the modification, loan payments are now interest-only through February 2015.  The mortgage bears interest at LIBOR plus an applicable spread which ranges from 250 to 350 basis points.  We entered into a floating-to-fixed interest rate swap which fixed LIBOR on the original loan at 1.5% through January 2018.  Effective August 1, 2013, we entered into a second floating-to-fixed interest rate swap which fixes LIBOR at 1.7% through January 2018 on the additional notional amount associated with the loan modification.  This loan is cross-defaulted with Hayden Ferry I, IV and V.
	Pursuant to the terms of that certain Agreement and Plan of Merger, dated as of September 4, 2013 (the “Merger Agreement”), by and among Parkway Properties, Inc. (the “Company”), Parkway Properties LP (“Parkway LP”), PKY Masters, LP, a wholly owned subsidiary of Parkway LP (“Merger Sub”), Thomas Properties Group, Inc. (“TPGI”) and Thomas Properties Group, L.P. (“TPG LP”), the Company and the Company’s general partner, Parkway Properties General Partners Inc. (the “General Partner”), entered into Amendment No. 1 (“Amendment No. 1”) to the Second Amended and Restated Agreement of Limited Partnership of Parkway Properties LP (the “Partnership Agreement”) effective as of December 19, 2013.
	On December 19, 2013, the Company completed the merger transactions contemplated by the Merger Agreement, pursuant to which TPGI merged with and into the Company, with the Company continuing as the surviving corporation (the “Parent Merger”), and TPG LP merged with and into Merger Sub, with TPG LP continuing as the surviving entity and an indirect wholly owned subsidiary of Parkway LP (the “Partnership Merger” and, together with the Parent Merger, the “Mergers”). Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Parent Merger, each outstanding share of common stock, par value $0.01 per share, of TPGI (“TPGI Common Stock”) was converted into the right to receive 0.3822 (the “Exchange Ratio”) shares of the Company’s common stock, par value $0.001 per share (“Parkway Common Stock”), with cash paid in lieu of fractional shares, and each share of TPGI limited voting stock, par value $0.01 per share (“TPGI Limited Voting Stock”), was converted into the right to receive a number of shares of newly created Company limited voting stock, par value $0.001 per share (“Parkway Limited Voting Stock”), equal to the Exchange Ratio. Similarly, at the effective time of the Partnership Merger, which occurred immediately prior to the Parent Merger, each outstanding limited partnership interest in TPG LP (“TPG LP Units”), including long term incentive units, was converted into the right to receive a number of limited partnership units in Parkway LP (the “Parkway LP Units”) equal to the Exchange Ratio. The Company issued 18,362,513 shares of Parkway Common Stock as consideration in the Parent Merger and Parkway LP issued 4,537,110 Parkway LP Units in the Partnership Merger. Based on the closing price of the Company’s common stock on December 19, 2013 as reported on the New York Stock Exchange, the aggregate value of the merger consideration paid or payable to former holders of TPGI Common Stock was approximately $331.4 million, and the aggregate value of Parkway LP Units, which are convertible into Parkway’s common stock, issued to former holders of TPG LP Units was approximately $81.9 million.
	In connection with the completion of the Mergers, on December 19, 2013, subsidiaries of the Company assumed three mortgages secured by the CityWestPlace properties.
	Two subsidiaries of the Company assumed two nonrecourse mortgage loans secured by CityWestPlace I and II and CityWestPlace III and IV. CityWestPlace is an approximately 1.4 million square foot office complex in Houston, Texas. The mortgage secured by CityWestPlace I and II, with a principal amount of approximately $117.7 million, bears interest at a rate of 6.16% and matures on July 6, 2016. The mortgage requires monthly payments of principal and interest and may not be prepaid prior to 90 days prior to the maturity date except that the mortgage may be defeased pursuant to customary defeasance procedures. The mortgage is nonrecourse to the Company except that Parkway LP has guaranteed to the lender the payment of certain amounts to be paid in connection with the recently executed Statoil Oil Services lease. The mortgage secured by CityWestPlace III and IV, for a principal amount of approximately $93.5 million, bears interest at a rate of 5.03% and matures on March 5, 2020. The mortgage requires monthly payments of principal and interest and may be prepaid with a prepayment fee equal to the greater of 1% of the amount prepaid or a yield maintenance based calculation, provided no prepayment fee is due during the last 60 days prior to maturity. Parkway LP has executed a guaranty of certain customary exceptions to non-recourse liability.

Segment Reporting [Abstract]	'
Segment Information	'
	Segment Information
	Parkway's primary business is the ownership and operation of office properties. The Company accounts for each office property or groups of related office properties as an individual operating segment.  Parkway has aggregated its individual operating segments into a single reporting segment due to the fact that the individual operating segments have similar operating and economic characteristics.
	The Company believes that the individual operating segments exhibit similar economic characteristics such as being leased by the square foot, sharing the same primary operating expenses and ancillary revenue opportunities and being cyclical in the economic performance based on current supply and demand conditions.  The individual operating segments are also similar in that revenues are derived from the leasing of office space to customers and each office property is managed and operated consistently in accordance with Parkway's standard operating procedures.  The range and type of customer uses of our properties is similar throughout our portfolio regardless of location or class of building and the needs and priorities of our customers do not vary from building to building.  Therefore, Parkway's management responsibilities do not vary from location to location based on the size of the building, geographic location or class.
	The following reflects net income (loss) attributable to common stockholders for office properties and total consolidated entities for the years ending December 31, 2012, 2011 and 2010.  Amounts presented as "Unallocated and Other" represent primarily income and expense associated with providing management services, corporate general and administration expense, interest expense on unsecured credit facility and preferred dividends.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2012
Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation and Principles of Consolidation
	The accompanying financial statements are prepared following U.S. generally accepted accounting principles ("GAAP") and the requirements of the Securities and Exchange Commission ("SEC").
	The consolidated financial statements include the accounts of Parkway Properties, Inc. ("Parkway" or "the Company"), its wholly-owned subsidiaries and joint ventures in which the Company has a controlling interest.  The other partners' equity interests in the consolidated joint ventures are reflected as noncontrolling interests in the consolidated financial statements.  Parkway also consolidates subsidiaries where the entity is a variable interest entity ("VIE") and Parkway is the primary beneficiary and has the power to direct the activities of the VIE and has the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE.  At December 31, 2012 and 2011, Parkway did not have any VIEs that required consolidation.  All significant intercompany transactions and accounts have been eliminated in the accompanying financial statements.
	The Company also consolidates certain joint ventures where it exercises significant control over major operating and management decisions, or where the Company is the sole general partner and the limited partners do not possess kick-out rights or other substantive participating rights.  The equity method of accounting is used for those joint ventures that do not meet the criteria for consolidation and where Parkway exercises significant influence but does not control these joint ventures.
Business	'
	Business
	The Company's operations are exclusively in the real estate industry, principally the operation, leasing, acquisition and ownership of office buildings.
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, the 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.  Although the Company believes the assumptions and estimates made are reasonable and appropriate, as discussed in the applicable sections throughout these consolidated 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 the Company's future operating results.  The Company's most significant estimates relate to impairments on real estate and other assets and purchase price allocations.
Real Estate Properties	'
	Real Estate Properties
	Real estate properties are carried at cost less accumulated depreciation.  Cost includes the carrying amount of the Company's investment plus any additional consideration paid, liabilities assumed, and improvements made subsequent to acquisition. Depreciation of buildings and building improvements is computed using the straight-line method over the estimated useful lives of the assets.  Depreciation of tenant improvements, including personal property, is computed using the straight-line method over the lesser of useful life or the term of the lease involved.  Maintenance and repair expenses are charged to expense as incurred.
	Balances of major classes of depreciable assets (in thousands) and their respective estimated useful lives are:
			31-Dec		31-Dec
	Asset Category	Estimated Useful Life	2012		2011
	Land	Non-depreciable	$	159,039	$	116,598
	Buildings and garages	40 years	1,369,493		801,619
	Building improvements	7 to 40 years	65,328		53,909

	Depreciation expense, including amounts recorded in discontinued operations, related to these assets of $50.7 million, $76.5 million, and $67.4 million was recognized in 2012, 2011 and 2010, respectively.
	The Company evaluates its real estate assets upon occurrence of significant adverse changes in its operations to assess whether any impairment indicators are present that affect the recovery of the carrying amount.  The carrying amount includes the net book value of tangible and intangible assets and liabilities.  Real estate assets are classified as held for sale or held and used.  Parkway records assets held for sale at the lower of carrying amount or fair value less cost to sell.  With respect to assets classified as held and used, Parkway recognizes an impairment loss if the carrying amount is not recoverable and exceeds the sum of undiscounted future cash flows expected to result from the use and eventual disposition of the asset.  The cash flow and fair value estimates are based on assumptions about employing the asset for its remaining useful life.  Factors considered in projecting future cash flows include, but are not limited to:  existing leases, future leasing and terminations, market rental rates, capital improvements, tenant improvements, leasing commissions, inflation and other known variables.  This market information is considered a Level 3 input as defined by Accounting Standards Certification ("ASC") 820, "Fair Value Measurements and Disclosures," ("ASC 820").  Upon impairment, Parkway recognizes an impairment loss to reduce the carrying value of the real estate asset to the estimate of its fair value.  During the year ended December 31, 2012, the impairment loss of $5.7 million related to an asset included in continuing operations and $3.5 million related to discontinued operations.
	The Company recognizes gains and losses from sales of real estate upon the realization at closing of the transfer of rights of ownership to the purchaser, receipt from the purchaser of an adequate cash down payment and adequate continuing investment by the purchaser.
	The Company classifies certain assets as held for sale based on management having the authority and intent of entering into commitments for sale transactions to close in the next twelve months.  The Company considers an office property as held for sale once it has executed a contract for sale, allowed the buyer to complete its due diligence review and received a substantial non-refundable deposit.  Until a buyer has completed its due diligence review of the asset, necessary approvals have been received and substantive conditions to the buyer's obligation to perform have been satisfied, the Company does not consider a sale to be probable.  When the Company identifies an asset as held for sale, it estimates the net realizable value of such asset and discontinues recording depreciation on the asset.  The Company records assets held for sale at the lower of carrying amount or fair value less cost to sell.
	Land available for sale, which consists of 12 acres of land in New Orleans, Louisiana, is carried at cost and is subject to evaluation for impairment.
Purchase Price Allocation	'
	Purchase Price Allocation
	Parkway allocates the purchase price of real estate to tangible and intangible assets and liabilities based on fair values.  Tangible assets consist of land, building, garage, building improvements and tenant improvements.  Intangible assets and liabilities consist of the value of above and below market leases, lease costs, the value of in-place leases, customer relationships and any value attributable to above or below market debt assumed with the acquisition.
	The Company may engage independent third-party appraisers to perform the valuations used to determine the fair value of these identifiable tangible and intangible assets.  These valuations and appraisals use commonly employed valuation techniques, such as discounted cash flow analyses. Factors considered in these analyses include an estimate of carrying costs during hypothetical expected lease-up periods considering current market conditions and costs to execute similar leases. Parkway also considers information obtained about each property as a result of its pre-acquisition due diligence, marketing and leasing activities in estimating the fair value of the tangible and intangible assets acquired. In estimating carrying costs, the Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods depending on specific local market conditions and depending on the type of property acquired. Additionally, Parkway estimates costs to execute similar leases including leasing commissions, legal and other related expenses to the extent that such costs are not already incurred in connection with a new lease origination as part of the transaction.
	The fair value of above or below market in-place lease values is the present value of the difference between the contractual amount to be paid pursuant to the in-place lease and the estimated current market lease rate expected over the remaining non-cancelable life of the lease.  The capitalized above market lease values are amortized as a reduction of rental income over the remaining term of the respective leases. The capitalized below market lease values are amortized as an increase to rental income over the remaining term of the respective leases.  Total amortization for above and below market leases, excluding amounts classified as discontinued operations, was a net reduction of rental income of $5.1 million and $3.0 million for the years ended December 31, 2012 and 2011, respectively, and a net increase of rental income of $163,000 for the year ended December 31, 2010.
	As of December 31, 2012, amortization of above and below market leases is projected as a net decrease to rental income as follows for the next five years (in thousands):
		Amount
	2013	$	(2,986	)
	2014	(1,057		)
	2015	(439		)
	2016	(409		)
	2017	(674		)
	The fair value of customer relationships represents the quantifiable benefits related to developing a relationship with the current customer.  Examples of these benefits would be growth prospects for developing new business with the existing customer, the ability to attract similar customers to the building, the customer's credit quality and expectations of lease renewals (including those existing under the terms of the lease agreement), among other factors.  Management believes that there would typically be little value associated with customer relationships that is in excess of the value of the in-place lease and their typical renewal rates.  Any value assigned to customer relationships is amortized over the remaining terms of the respective leases plus any expected renewal periods as a lease cost amortization expense.  Currently, the Company has no value assigned to customer relationships.
	The fair value of at market in-place leases is the present value associated with re-leasing the in-place lease as if the property was vacant.  Factors to be considered include estimates of carrying costs during hypothetical expected lease-up periods considering current market conditions and costs to execute similar leases.  In estimating carrying costs, the Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods.  The value of at market in-place leases is amortized as a lease cost amortization expense over the expected life of the lease.  Total amortization expense for the value of in-place leases, excluding amounts classified as discontinued operations, was $15.9 million, $12.3 million, and $5.2 million for the years ended December 31, 2012, 2011 and 2010, respectively.
	As of December 31, 2012, amortization expense for the value of in-place leases is projected as follows for the next five years (in thousands):
		Amount
	2013	$	20,898
	2014	16,201
	2015	13,656
	2016	11,530
	2017	7,850
	A separate component of the fair value of in-place leases is identified for the lease costs.  The fair value of lease costs represents the estimated commissions and legal fees paid in connection with the current leases in place.  Lease costs are amortized over the non-cancelable terms of the respective leases as lease cost amortization expense.
	In no event does the amortization period for intangible assets exceed the remaining depreciable life of the building. Should a customer terminate its lease, the unamortized portion of the tenant improvement, in-place lease value, lease cost and customer relationship intangibles would be charged to expense.  Additionally, the unamortized portion of above market in-place leases would be recorded as a reduction to rental income and the below market in-place lease value would be recorded as an increase to rental income.
Goodwill	'
	Goodwill
	During 2011, the Company early adopted Accounting Standards Updated ("ASU") 2011-8, which allows an entity to first assess the qualitative factors in determining when a two-step quantitative goodwill impairment test is necessary.  If an entity determines, based on qualitative factors, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the entity would then be required to calculate the fair value of the reporting entity.  The Company acquired goodwill in 2011 when it closed on the agreement with Eola Capital, LLC and related entities ("Eola") in which Eola contributed its property management company to Parkway.  During 2012, the company evaluated certain qualitative factors and determined that it was necessary to apply the two-step quantitative impairment test.  During this process the Company determined that the management contracts related to its goodwill were impaired due to the fair value of these management contracts being estimated at $19.0 million as compared to the carrying amount of $46.1 million.  Next, the Company computed the fair value of the assets and liabilities associated with management contracts and determined that the associated goodwill was impaired.  During the year ended December 31, 2012, the Company recorded a $42.0 million non-cash impairment loss, net of deferred tax liability, associated with the Company's investment in management contracts and goodwill.  The Company's strategy related to the third-party management business has changed since the acquisition of these contracts.  When they were acquired, the Company's strategy was to grow the third-party business and continue to add management contracts in Parkway's various markets.  While the Company still views the cash flow from this business as positive and the additional management contracts gives Parkway scale and critical mass in some of its key markets, the Company is no longer actively seeking to grow this portion of the business.
Allowance for Doubtful Accounts	'
	Allowance for Doubtful Accounts
	Accounts receivable are reduced by an allowance for amounts that the Company estimates to be uncollectible.  The receivable balance is comprised primarily of rent and expense reimbursement income due from the customers.  Management evaluates the adequacy of the allowance for doubtful accounts considering such factors as the credit quality of the customers, delinquency of payment, historical trends and current economic conditions.  The Company provides an allowance for doubtful accounts for customer balances that are over 90 days past due and for specific customer receivables for which collection is considered doubtful.
Cash Equivalents	'
	Cash Equivalents
	The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.
Noncontrolling Interest	'
	Noncontrolling Interest
	Noncontrolling Interest – Real Estate Partnerships
	At December 31, 2012 and 2011, the Company had an interest in one and two joint ventures, respectively, whose operations are included in its consolidated financial statements.  These joint ventures were originally structured such that the Company would own a 25% and 30% interest in Parkway Properties Office Fund, LP ("Fund I") and Parkway Properties Office Fund II, LP ("Fund II"), respectively.
	Parkway serves as the general partner of Fund II and provides asset management, property management, leasing and construction management services to the fund, for which it is paid market-based fees.  Cash is distributed from Fund II pro rata to each partner until a 9% annual cumulative preferred return is received and invested capital is returned.  Thereafter, 56% will be distributed to Parkway's partner in Fund II, Teacher Retirement System of Texas ("TRST") and 44% to Parkway.  The term of Fund II is seven years from the date the fund was fully invested, or until February 2019, with provisions to extend the term for two additional one-year periods at the Company's discretion.
	The Company previously entered into an agreement to sell its interest in 13 office properties totaling 2.7 million square feet owned by Parkway Properties Office Fund, L.P. ("Fund I") to its existing partner in the fund for a gross sales price of $344.3 million.  As of July 1, 2012, the Company had completed the sale of all 13 Fund I assets.
	Noncontrolling interest in real estate partnerships represents the other partners' proportionate share of equity in the partnerships discussed above at December 31, 2012 and 2011.  Income is allocated to noncontrolling interest based on the weighted average percentage ownership during the year.
Revenue Recognition	'
	Revenue Recognition
	Revenue from real estate rentals is recognized on a straight-line basis over the terms of the respective leases.  The cumulative difference between lease revenue recognized under this method and contractual lease payment terms is recorded as straight-line rent receivable on the accompanying balance sheets.  The straight-line rent adjustment increased revenue by $15.3 million, $6.1 million and $1.2 million in 2012, 2011 and 2010, respectively.
	When the Company is the owner of the customer improvements, the leased space is ready for its intended use when the customer improvements are substantially completed. In limited instances, when the customer is the owner of the customer improvements, straight-line rent is recognized when the customer takes possession of the unimproved space.
	The leases also typically provide for customer reimbursement of a portion of common area maintenance and other operating expenses.  Property operating cost recoveries from customers ("expense reimbursements") are recognized as revenue in the period in which the expenses are incurred.  The computation of expense reimbursements is dependent on the provisions of individual customer leases.  Most customers make monthly fixed payments of estimated expense reimbursements.  The Company makes adjustments, positive or negative, to expense reimbursement income quarterly to adjust the recorded amounts to the Company's best estimate of the final property operating costs based on the most recent quarterly budget.  After the end of the calendar year, the Company computes each customer's final expense reimbursements and issues a bill or credit for the difference between the actual amount and the amounts billed monthly during the year.
	Management company income represents market-based fees earned from providing management, construction, leasing, brokerage and acquisition services to third parties. Management fee income is computed and recorded monthly in accordance with the terms set forth in the stand alone management service agreements. Leasing and brokerage commissions, as well as salary and administrative fees, are recognized pursuant to the terms of the stand-alone agreements at the time underlying leases are signed, which is the point at which the earnings process is complete and collection of the fees is reasonably assured. Fees relating to the purchase or sale of property are recognized when the earnings process is complete and collection of the fees is reasonably assured, which usually occurs at closing. All fees on Company-owned properties and consolidated joint ventures are eliminated in consolidation.  The Company recognizes its share of fees earned from unconsolidated joint ventures in management company income.
Amortization	'
	Amortization
	Debt origination costs are deferred and amortized using a method that approximates the effective interest method over the term of the loan.  Leasing costs are deferred and amortized using the straight-line method over the term of the respective lease.
Early Extinguishment of Debt	'
	Early Extinguishment of Debt
	When outstanding debt is extinguished, the Company records any prepayment premium and unamortized loan costs to interest expense.
Derivative Financial Instruments	'
	Derivative Financial Instruments
	The Company recognizes all derivative instruments on the balance sheet at their fair value.  Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income (loss), depending on whether a derivative is designated as part of a hedge transaction and, if it is, the type of hedge transaction.  The ineffective portion of the hedge, if any, is immediately recognized in earnings.
Share-Based and Long-Term Compensation	'
	Share-Based and Long-Term Compensation
	Effective May 1, 2010, the stockholders of the Company approved Parkway's 2010 Omnibus Equity Incentive Plan (the "2010 Equity Plan") that authorized the grant of up to 600,000 equity based awards to employees and directors of the Company.   The 2010 Equity Plan replaced the Company's 2003 Equity Incentive Plan and the 2001 Non-Employee Directors Equity Compensation Plan.  At present, it is Parkway's intention to grant restricted shares and/or deferred incentive share units instead of stock options although the 2010 Equity Plan authorizes various forms of incentive awards, including options.  The 2010 Equity Plan has a ten-year term.
	On May 12, 2011, the Board of Directors approved Parkway's 2011 Employee Inducement Award Plan that authorized the grant of up to 149,573 restricted shares and/or deferred incentive share units to employees and directors of the Company in connection with the combination with Eola.  The Plan shall continue in effect until the earlier of (a) its termination by the Board or (b) the date on which all of the shares of stock available for issuance under the Plan have been issued; provided that awards outstanding on that date shall survive in accordance with their terms.
	Compensation expense, including estimated forfeitures, for service-based awards is recognized over the expected vesting period.  The total compensation expense for the long-term equity incentive awards is based upon the fair value of the shares on the grant date, adjusted for estimated forfeitures.  Time-based restricted shares and deferred incentive share units are valued based on the New York Stock Exchange closing market price of Parkway common shares (NYSE:  PKY) as of the date of grant.  The grant date fair value for awards that are subject to market conditions is determined using a simulation pricing model developed to specifically accommodate the unique features of the awards.
	Restricted shares and deferred incentive share units are forfeited if an employee leaves the Company before the vesting date, except in the case of the employee's death or permanent disability or upon termination following a change of control. Shares and/or units that are forfeited become available for future grant under the 2010 Equity Plan.
	The Company also adopted a long-term cash incentive that was designed to reward significant outperformance over the three year period which began July 1, 2010.  The total compensation expense for the long-term cash incentive awards is based upon the estimated fair value of the award on the grant date and adjusted as necessary each reporting period.  The long-term cash incentive awards are accounted for as a liability-classified award on the Company's 2012 and 2011 consolidated balance sheets.  The grant date and quarterly fair value estimates for awards that are subject to a market condition are determined using a simulation pricing model developed to specifically accommodate the unique features of the awards.
Income Taxes	'
	Income Taxes
	The Company elected to be taxed as a REIT under the Internal Revenue Code, commencing with its taxable year ended December 31, 1997.  To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement that it currently distribute at least 90% of its adjusted taxable income to its stockholders.  It is management's current intention to adhere to these requirements and maintain the Company's REIT status, and the Company was in compliance with all REIT requirements at December 31, 2012.  As a REIT, the Company generally will not be subject to corporate level federal income tax on taxable income it distributes currently to its stockholders.  If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years.  Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed taxable income. In addition, taxable income from non-REIT activities managed through TRSs is subject to federal, state and local income taxes.
	Effective May 18, 2011, the Company acquired the Eola management company and contributed the entity into a taxable REIT subsidiary ("TRS") wholly-owned by the operating partnership.  In connection with the purchase of the Eola management company, the TRS recorded a deferred income tax liability of $14.8 million.  At December 31, 2012, the Company carried a deferred tax liability of $2.0 million, as compared to a balance of $14.3 million at December 31, 2011.  The balance was reduced during the fourth quarter of 2012 as a result of the reduction in the value of the Company's management contracts to $19.0 million.  The TRS pays income taxes at the federal and state level.
Net Loss Per Common Share	'
	Net Loss Per Common Share
	Basic earnings per share ("EPS") is computed by dividing loss attributable to common stockholders by the weighted-average number of common shares outstanding for the year.  In arriving at net loss attributable to common stockholders, preferred stock dividends are deducted.  Diluted EPS reflects the potential dilution that could occur if share equivalents such as employee stock options, restricted shares and deferred incentive share units were exercised or converted into common stock that then shared in the earnings of Parkway.

	Recent Accounting Pronouncements
	In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-4, "Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS", which change the wording used to describe the requirements in U.S. GAAP for measuring fair value, changes certain fair value measurement principles and enhances disclosure requirements for fair value measurements.  The FASB does not intend for ASU 2011-4to result in a change in the application of the requirements in ASC 820.  The requirements of ASU 2011-4 will be effective prospectively for interim and annual periods beginning after December 15, 2011.  At March 31, 2012, the Company had implemented ASU 2011-4.
	In June 2011, the FASB issued ASU 2011-5, "Comprehensive Income", which modifies reporting requirements for comprehensive income in order to increase the prominence of items reported in other comprehensive income in the financial statements.  ASU 2011-5 requires presentation of either a single continuous statement of comprehensive income or two separate, but consecutive statements in which the first statement presents net income and its components followed by a second statement that presents total other comprehensive income, the components of other comprehensive income, and total comprehensive income. The requirements of ASU 2011-5 will be effective for interim and annual periods beginning after December 15, 2011.  At March 31, 2012, the Company had implemented ASU 2011-5.

The interest rate on the credit facilities is based on LIBOR plus 160 to 235 basis points, depending upon overall Company leverage as defined in the loan agreements for the Company's credit facility, with the current rate set at 160 basis points. Additionally, the Company pays fees on the unused portion of the credit facilities ranging between 25 and 35 basis points based upon usage of the aggregate commitment, with the current rate set at 25 basis points.

[2]

The interest rate on the term loan is based on LIBOR plus an applicable margin of 1.5% to 2.3% depending on overall Company leverage (with the current rate set at 1.5%). On September 28, 2012, the Company executed two floating-to-fixed interest rate swaps totaling $125 million, locking LIBOR at 0.7% for five years which is effective October 1, 2012.

[1]

For balance sheet purposes, the Company has reclassified these mortgages totaling $254.4 million to Liabilities Related to Assets Held for Sale at December 31, 2011.

[2]

The mortgage loans secured by these properties have variable interest rates that have been fixed by interest rate swap agreements.

[3]

The Company assumed the existing loan on NASCAR Plaza upon acquisition in December 2012. The note bears interest at a stated interest rate of 4.7% and has been marked-to-market for GAAP purposes.

[4]

Effective December 31, 2012 the Company assumed the mortgage secured by NASCAR Plaza and also the swap associated with this mortgage. The notional amount of the swap is $30 million which fixes LIBOR at 2.3%, which resulted in an all-in interest rate of 3.4%. The interest rate swap matures on FebruaryB 1, 2016.

[5]

The Hayden Ferry II mortgage provides for quarterly payments of $625,000 through February 2015 with payments based on a 25 year amortization thereafter until maturity. Additionally, the mortgage bears interest at LIBOR plus the applicable spread which ranges between 250 and 350 basis points. Fund II entered into an interest rate swap that fixed the LIBOR rate associated with this loan at 1.5% through January 25, 2018. This loan is cross-defaulted with Hayden Ferry I.

[1]

The mortgage loans secured by these properties have variable interest rates that have been fixed by interest rate swap agreements.

[2]

The Company assumed the existing loan on NASCAR Plaza upon acquisition in December 2012. The note bears interest at a stated interest rate of 4.7% and has been marked-to-market for GAAP purposes.

[3]

Effective December 31, 2012 the Company assumed the mortgage secured by NASCAR Plaza and also the swap associated with this mortgage. The notional amount of the swap is $30 million which fixes LIBOR at 2.3%, which resulted in an all-in interest rate of 3.4%. The interest rate swap matures on FebruaryB 1, 2016.

[4]

The Hayden Ferry II mortgage provides for quarterly payments of $625,000 through February 2015 with payments based on a 25 year amortization thereafter until maturity. Additionally, the mortgage bears interest at LIBOR plus the applicable spread which ranges between 250 and 350 basis points. Fund II entered into an interest rate swap that fixed the LIBOR rate associated with this loan at 1.5% through January 25, 2018. This loan is cross-defaulted with Hayden Ferry I.
