	Real Estate

	As of June 30, 2014, and December 31, 2013, the cost basis and accumulated depreciation and amortization related to our consolidated real estate properties and related lease intangibles were as follows (in thousands):


							Lease Intangibles
							Assets						Liabilities
										Acquired Above-Market Leases			Acquired Below-Market Leases
			Buildings and Improvements				Other Lease Intangibles
	as of June 30, 2014
	Cost		$	2,266,807			$	296,182		$	19,171		$	(72,839	)

	Less: accumulated depreciation and amortization		(622,719		)		(174,401		)	(13,942		)	51,521

	Net		$	1,644,088			$	121,781		$	5,229		$	(21,318	)




							Lease Intangibles
							Assets						Liabilities
										Acquired Above-Market Leases			Acquired Below-Market Leases
			Buildings and Improvements				Other Lease Intangibles
	as of December 31, 2013
	Cost		$	2,255,384			$	305,233		$	19,264		$	(76,750	)

	Less: accumulated depreciation and amortization		(586,585		)		(177,088		)	(13,045		)	52,180

	Net		$	1,668,799			$	128,145		$	6,219		$	(24,570	)


	We amortize the value of in-place leases, in-place tenant improvements and in-place leasing commissions to expense over the initial term of the respective leases. The tenant relationship values are amortized to expense over the tenants’ respective initial lease terms and any anticipated renewal periods, but in no event does the amortization period for intangible assets or liabilities exceed the remaining depreciable life of the building. Should a tenant terminate its lease, the unamortized portion of the acquired lease intangibles related to that tenant would be charged to expense. The estimated remaining average useful lives for acquired lease intangibles range from an ending date of July 2014 to an ending date of November 2025. Anticipated amortization associated with the acquired lease intangibles for each of the following five years is as follows (in thousands):


	July - December 2014	$	6,386

	2015	$	9,305

	2016	$	6,362

	2017	$	3,816

	2018	$	3,025


	Impairment of Real Estate Related Assets

	For our consolidated real estate assets, we monitor events and changes in circumstances indicating that the carrying amounts of the real estate assets may not be recoverable. When such events or changes in circumstances are present, we assess potential impairment by comparing estimated future undiscounted cash flows expected to be generated over the life of the asset including its eventual disposition, to the carrying amount of the asset. In the event that the carrying amount exceeds the estimated future undiscounted cash flows and also exceeds the fair value of the asset, we recognize an impairment loss to adjust the carrying amount of the asset to its estimated fair value. Our process to estimate the fair value of an asset involves using third-party broker valuation estimates, bona fide purchase offers or the expected sales price of an executed sales agreement, which would be considered Level 1 or Level 2 assumptions within the fair value hierarchy. To the extent that this type of third-party information is unavailable, we estimate projected cash flows and a risk-adjusted rate of return that we believe would be used by a third-party market participant in estimating the fair value of an asset. This is considered a Level 3 assumption within the fair value hierarchy. These projected cash flows are prepared internally by the Company’s asset management professionals and are updated quarterly to reflect in place and projected leasing activity, market revenue and expense growth rates, market capitalization rates, discount rates, and changes in economic and other relevant conditions. The Company’s Chief Financial Officer, Chief Investment Officer and Chief Accounting Officer review these projected cash flows to assure that the valuation is prepared using reasonable inputs and assumptions which are consistent with market data or with assumptions that would be used by a third party market participant and assume the highest and best use of the real estate investment. For the six months ended June 30, 2014 and 2013, we recorded non-cash impairment charges of approximately $8.2 million and $4.9 million, respectively, related to the impairment of consolidated real estate assets. The impairment losses recorded were primarily related to assets assessed for impairment due to changes in management's estimates of the intended hold periods.

For our unconsolidated real estate assets, at each reporting date we compare the estimated fair value of our investment to the carrying amount. An impairment charge is recorded to the extent the fair value of our investment is less than the carrying amount and the decline in value is determined to be other than a temporary decline. We had no impairment charges related to our investments in unconsolidated entities for the six months ended June 30, 2014 or 2013.

In evaluating our investments for impairment, management makes several estimates and assumptions, including, but not limited to, the projected date of disposition and sales price for each property, the estimated future cash flows of each property during our estimated ownership period, and for unconsolidated investments, the estimated future distributions from the investment. A change in these estimates and assumptions could result in understating or overstating the carrying amount of our investments which could be material to our financial statements.

We undergo continuous evaluations of property level performance, credit market conditions and financing options. If our assumptions regarding the cash flows expected to result from the use and eventual disposition of our properties decrease or our expected hold periods decrease, we may incur future impairment charges on our real estate related assets. In addition, we may incur impairment charges on assets classified as held for sale in the future if the carrying amount of the asset upon classification as held for sale exceeds the estimated fair value, less costs to sell.

Revenue Recognition

We recognize rental income generated from all leases of consolidated real estate assets on a straight-line basis over the terms of the respective leases, including the effect of rent holidays, if any. The total net increase to rental revenues due to straight-line rent adjustments for the three months ended June 30, 2014 and 2013, was approximately $1.4 million and $2.1 million, respectively, and includes amounts recognized in discontinued operations. The total net increase to rental revenues due to straight-line rent adjustments for the six months ended June 30, 2014 and 2013, was approximately $2.9 million and $5.0 million, respectively, and includes amounts recognized in discontinued operations. As discussed above, our rental revenue also includes amortization of acquired above- and below-market leases. The total net increase to rental revenues due to the amortization of acquired above- and below-market leases for the three months ended June 30, 2014 and 2013, was approximately $1.1 million and $2.3 million, respectively, and includes amounts recognized in discontinued operations. The total net increase to rental revenues due to the amortization of acquired above- and below-market leases for the six months ended June 30, 2014 and 2013, was approximately $2.3 million and $4.6 million, respectively, and includes amounts recognized in discontinued operations. Revenues relating to lease termination fees are recognized on a straight-line basis amortized from the time that a tenant’s right to occupy the leased space is modified through the end of the revised lease term. For the three months ended June 30, 2014 and 2013, we recognized lease termination fees of approximately $0.7 million and $0.2 million, which includes amounts recognized in discontinued operations. For the six months ended June 30, 2014 and 2013, we recognized lease termination fees of approximately $0.9 million, and $0.3 million which includes amounts recognized in discontinued operations.

Income Taxes

We have elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), and have qualified as a REIT since the year ended December 31, 2004. To qualify as a REIT, we must meet a number of organizational and operational requirements, including a requirement that we distribute at least 90% of our REIT taxable income (excluding net capital gains) to our stockholders. As a REIT, we generally will not be subject to federal income tax at the corporate level (except to the extent we distribute less than 100% of our taxable income and/or net taxable capital gains). We generate certain of our taxable income through various taxable REIT subsidiary (“TRS”) entities. The taxable income of our TRS entities is subject to applicable federal, state, and local income and margin taxes.

As of June 30, 2014, we have deferred tax liabilities of approximately $0.9 million and deferred tax assets, net of related valuation allowances, of less than $0.1 million related to various state taxing jurisdictions. At December 31, 2013, we had deferred tax liabilities of approximately $1.3 million and deferred tax assets, net of related valuation allowances, of less than $0.1 million related to various state taxing jurisdictions.

We recognize in our financial statements the impact of our tax return positions if it is more likely than not that the tax position will be sustained upon examination (defined as a greater than fifty percent likelihood of being sustained upon audit, based on the technical merits of the tax position). Tax positions that meet the more likely than not threshold are measured at the largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement. We recognize the tax implications of the portion of a tax position that does not meet the more likely than not threshold together with the accrued interest and penalties in the financial statements as a component of the provision for income taxes.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]	'

	New Accounting Pronouncements

	In February 2013 the Financial Accounting Standards Board (“FASB”) issued updated guidance for the measurement and disclosure of obligations. The guidance requires an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance in the update also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. This guidance is effective for the first interim or annual period beginning on or after December 15, 2013. The adoption of this guidance did not have a material impact on our financial statements or disclosures.

	In April 2014 the FASB issued guidance that changes the criteria for reporting a discontinued operation. Under the new guidance, only a disposal of a component that represents a major strategic shift of an organization qualifies for discontinued operations reporting. The guidance also requires expanded disclosures about discontinued operations and new disclosures in regards to individually significant disposals that do not qualify for discontinued operations reporting. This guidance is effective for the first interim or annual period beginning on or after December 15, 2014. Early adoption is permitted, but only for disposals that have not been reported in previously-issued financial statements. We are currently evaluating the impact this guidance will have on our financial statements when adopted.

	In May 2014, the FASB issued guidance to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP and International Financial Reporting Standards. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2016. We are currently evaluating the impact this guidance will have on our financial statements when adopted.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair value, as defined by GAAP, is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the fair value hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the fair value hierarchy) has been established.

Financial Instruments not Reported at Fair Value

Financial instruments held at June 30, 2014, and December 31, 2013, but not measured at fair value on a recurring basis include cash and cash equivalents, restricted cash, accounts receivable, notes payable, accounts payable, payables to related parties, accrued liabilities and other liabilities. With the exception of notes payable, the financial statement carrying amounts of these items approximate their fair values due to their short-term nature. Estimated fair values for notes payable have been determined using recent trading activity and/or bid-ask spreads and are classified as Level 2 in the fair value hierarchy. Carrying amounts and the related estimated fair value of our notes payable as of June 30, 2014, and December 31, 2013, are as follows (in thousands):

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Impairment of Real Estate Related Assets

We have recorded non-cash impairment charges related to a reduction in the fair value of certain of our assets. The inputs used to calculate the fair value of these assets included projected cash flows and a risk-adjusted rate of return that we estimated would be used by a market participant in valuing these assets or by obtaining third-party broker valuation estimates, bona fide purchase offers, or the expected sales price of an executed sales agreement.

During the six months ended June 30, 2014, we recorded impairment losses of approximately $8.2 million. The following table summarizes those assets which were measured at fair value and impaired during 2014 (in thousands):

	Our notes payable was approximately $1.5 billion in principal amount at June 30, 2014. As of June 30, 2014, all of our outstanding debt is fixed rate debt, with the exception of our construction loan for Two BriarLake Plaza which has an outstanding balance of approximately $32.6 million. At June 30, 2014, the stated annual interest rates on our notes payable, excluding mezzanine financing, ranged from 3.04% to 6.22%. Included in our notes payable balance, we also have an approximately $14.8 million property-related mezzanine loan with a stated annual interest rate at June 30, 2014, of 9.80%. The effective weighted average annual interest rate for all of our borrowings is approximately 5.65%.

	Our loan agreements generally require us to comply with certain reporting and financial covenants. As of June 30, 2014, we believe we were in compliance with the covenants under each of our loan agreements, and our notes payable had maturity dates that range from January 2015 to August 2021.

	Credit Facility

	Through our operating partnership, Tier OP, we have a secured credit agreement providing for borrowings under a revolving line of credit of up to $260.0 million, based on meeting certain financial thresholds. Subject to lender approval, certain conditions, and payment of certain activation fees to the agent and lenders, this may be increased up to $500.0 million in the aggregate. The facility matures on June 20, 2017, and may be extended for an additional one-year term and an additional six-month term. The annual interest rate on the credit facility is equal to either, at our election, (1) the “base rate” (calculated as the greatest of (i) the agent’s “prime rate”; (ii) 0.5% above the Federal Funds Effective Rate; or (iii) LIBOR for an interest period of one month plus 1.0%) plus 1.35% or (2) LIBOR plus 2.35%. All amounts owed under the credit facility are guaranteed by us and certain subsidiaries of Tier OP. Draws under the credit facility are secured by a perfected first priority lien and security interest in a collateral pool consisting of six properties owned by certain of our subsidiaries. As of June 30, 2014, borrowings capacity under the facility was limited based on certain financial thresholds to approximately $206.6 million and there were no borrowings outstanding.

	Limited Partnership Units

	At June 30, 2014, Tier OP had 432,586 units of limited partnership interest held by third parties. These units of limited partnership interest are convertible into an equal number of shares of our common stock.

	Series A Convertible Preferred Stock

	On September 4, 2012, we issued 10,000 shares of Series A participating, voting, convertible preferred stock (the “Series A Convertible Preferred Stock”) to Behringer Harvard REIT I Services Holdings, LLC. Management estimated the fair value of the shares to be approximately $2.7 million at the date of issuance. The maximum redemption value of the Series A Convertible Preferred Stock at June 30, 2014, is not greater than the fair value of these shares estimated at the date of issuance. Therefore, no adjustment to the book value of these shares has been recorded subsequent to their issuance.

	Stock Plans

	Our 2005 Incentive Award Plan allows for equity-based incentive awards to be granted to our Employees and Key Personnel (as defined in the plan) as detailed below:

	Stock options. As of June 30, 2014, we had outstanding options held by our independent directors to purchase 75,000 shares of our common stock at a weighted average exercise price of $6.69 per share. These options have a maximum term of 10 years and were exercisable one year after the date of grant. The options were anti-dilutive to earnings per share for each period presented.

	Restricted stock units. As of June 30, 2014, we had 73,122 restricted stock units outstanding, held by our independent directors. We issued 35,715 restricted stock units on June 18, 2014 with a grant price of $4.20 per unit. These units vest on July 19, 2015. We issued 37,407 restricted stock units on June 21, 2013 with a grant price of $4.01 per unit. These units vest on July 22, 2014. Subsequent to the vesting, the restricted stock units will be converted to an equivalent number of shares of common stock upon the earlier to occur of the following events or dates: (i) separation from service for any reason other than cause; (ii) a change in control of the Company; (iii) death; or (iv) specific dates chosen by the independent directors that range from June 2015 to June 2019. Expense is measured at the grant date based on the estimated fair value of the award and is recognized over the vesting period. The restricted units were anti-dilutive to earnings per share for each period presented.

	Restricted stock. As of June 30, 2014, we had 711,376 shares of restricted stock outstanding, held by employees. Restrictions on these shares lapse in 25% increments annually over the four-year period following the grant date. Compensation cost is measured at the grant date, based on the estimated fair value of the award and is recognized as expense over the service period based on a tiered lapse schedule and estimated forfeiture rates. The restricted stock was anti-dilutive to earnings per share for each period presented. The following is a summary of the number of shares of restricted stock outstanding as of June 30, 2014 and 2013:

	As of June 30, 2014, we had commitments of approximately $56.6 million for future tenant improvements, leasing commissions and completing renovations at a recently disposed property.

	We have Employment Agreements (collectively, the “Employment Agreements”) with each of the following executive officers: Scott W. Fordham, our Chief Executive Officer and President; Dallas E. Lucas, our Chief Financial Officer; William J. Reister, our Chief Investment Officer and Executive Vice President; Telisa Webb Schelin, our Senior Vice President - Legal, General Counsel and Secretary; and James E. Sharp, our Chief Accounting Officer. The term of each Employment Agreement ends on May 31, 2017, provided that the term will automatically continue for an additional one year period unless either party provides 60 days written notice of non-renewal prior to the expiration of the initial term. The agreements provide for lump sum payments and an immediate lapse of restrictions on compensation received under the long-term incentive plan upon termination of employment without cause. As a result, in the event the Company terminated all of these agreements as of June 30, 2014, we would recognize approximately $9.1 million in compensation expense (without regard to any potential reductions required under the Employment Agreements for amounts in excess of thresholds set forth in Section 280G of the Code).

	We are subject, from time to time, to various legal proceedings and claims that arise in the ordinary course of business. While the resolution of these matters cannot be predicted with certainty, management believes, based on currently available information, that the final outcome of such matters, individually or in the aggregate, will not have a material adverse effect on our results of operations or financial condition.

	On each of September 17 and November 28, 2012, lawsuits seeking class action status were filed in the United States District Court for the Northern District of Texas (Dallas Division). On January 4, 2013, these two lawsuits were consolidated by the Court. The plaintiffs purported to file the suit individually and on behalf of all others similarly situated, referred to herein as “Plaintiffs.”
	Plaintiffs named us, Behringer Harvard Holdings, LLC, our previous sponsor, as well as the directors at the time of the allegations: Robert M. Behringer, Robert S. Aisner, Ronald Witten, Charles G. Dannis and Steven W. Partridge (individually a “Director” and collectively the “Directors”) and Scott W. Fordham, the Company’s Chief Executive Officer and President, and James E. Sharp, the Company’s Chief Accounting Officer (collectively, the “Officers”), as defendants. In the amended complaint filed on February 1, 2013, the Officers were dismissed from the consolidated suit.
	Plaintiffs alleged that (1) the Directors each individually breached various fiduciary duties purportedly owed to Plaintiffs, (2) the Directors violated Sections 14(a) and (e) and Rules 14a-9 and 14e-2(b) of and under federal securities law and (3) the defendants were unjustly enriched by the purported failures to provide complete and accurate disclosure regarding, among other things, the value of our common stock and the source of funds used to pay distributions.
	On March 27, 2014, the United States District Court for the Northern District of Texas granted the motion to dismiss the lawsuit with prejudice from which no appeal was taken.

	We amortize the value of in-place leases, in-place tenant improvements and in-place leasing commissions to expense over the initial term of the respective leases. The tenant relationship values are amortized to expense over the tenants’ respective initial lease terms and any anticipated renewal periods, but in no event does the amortization period for intangible assets or liabilities exceed the remaining depreciable life of the building. Should a tenant terminate its lease, the unamortized portion of the acquired lease intangibles related to that tenant would be charged to expense. The estimated remaining average useful lives for acquired lease intangibles range from an ending date of July 2014 to an ending date of November 2025. Anticipated amortization associated with the acquired lease intangibles for each of the following five years is as follows (in thousands):

Impairment of Real Estate Related Assets	'
	Impairment of Real Estate Related Assets

	For our consolidated real estate assets, we monitor events and changes in circumstances indicating that the carrying amounts of the real estate assets may not be recoverable. When such events or changes in circumstances are present, we assess potential impairment by comparing estimated future undiscounted cash flows expected to be generated over the life of the asset including its eventual disposition, to the carrying amount of the asset. In the event that the carrying amount exceeds the estimated future undiscounted cash flows and also exceeds the fair value of the asset, we recognize an impairment loss to adjust the carrying amount of the asset to its estimated fair value. Our process to estimate the fair value of an asset involves using third-party broker valuation estimates, bona fide purchase offers or the expected sales price of an executed sales agreement, which would be considered Level 1 or Level 2 assumptions within the fair value hierarchy. To the extent that this type of third-party information is unavailable, we estimate projected cash flows and a risk-adjusted rate of return that we believe would be used by a third-party market participant in estimating the fair value of an asset. This is considered a Level 3 assumption within the fair value hierarchy. These projected cash flows are prepared internally by the Company’s asset management professionals and are updated quarterly to reflect in place and projected leasing activity, market revenue and expense growth rates, market capitalization rates, discount rates, and changes in economic and other relevant conditions. The Company’s Chief Financial Officer, Chief Investment Officer and Chief Accounting Officer review these projected cash flows to assure that the valuation is prepared using reasonable inputs and assumptions which are consistent with market data or with assumptions that would be used by a third party market participant and assume the highest and best use of the real estate investment. For the six months ended June 30, 2014 and 2013, we recorded non-cash impairment charges of approximately $8.2 million and $4.9 million, respectively, related to the impairment of consolidated real estate assets. The impairment losses recorded were primarily related to assets assessed for impairment due to changes in management's estimates of the intended hold periods.

	For our unconsolidated real estate assets, at each reporting date we compare the estimated fair value of our investment to the carrying amount. An impairment charge is recorded to the extent the fair value of our investment is less than the carrying amount and the decline in value is determined to be other than a temporary decline. We had no impairment charges related to our investments in unconsolidated entities for the six months ended June 30, 2014 or 2013.

	In evaluating our investments for impairment, management makes several estimates and assumptions, including, but not limited to, the projected date of disposition and sales price for each property, the estimated future cash flows of each property during our estimated ownership period, and for unconsolidated investments, the estimated future distributions from the investment. A change in these estimates and assumptions could result in understating or overstating the carrying amount of our investments which could be material to our financial statements.

	We undergo continuous evaluations of property level performance, credit market conditions and financing options. If our assumptions regarding the cash flows expected to result from the use and eventual disposition of our properties decrease or our expected hold periods decrease, we may incur future impairment charges on our real estate related assets. In addition, we may incur impairment charges on assets classified as held for sale in the future if the carrying amount of the asset upon classification as held for sale exceeds the estimated fair value, less costs to sell.

Revenue Recognition	'
	Revenue Recognition

	We recognize rental income generated from all leases of consolidated real estate assets on a straight-line basis over the terms of the respective leases, including the effect of rent holidays, if any. The total net increase to rental revenues due to straight-line rent adjustments for the three months ended June 30, 2014 and 2013, was approximately $1.4 million and $2.1 million, respectively, and includes amounts recognized in discontinued operations. The total net increase to rental revenues due to straight-line rent adjustments for the six months ended June 30, 2014 and 2013, was approximately $2.9 million and $5.0 million, respectively, and includes amounts recognized in discontinued operations. As discussed above, our rental revenue also includes amortization of acquired above- and below-market leases. The total net increase to rental revenues due to the amortization of acquired above- and below-market leases for the three months ended June 30, 2014 and 2013, was approximately $1.1 million and $2.3 million, respectively, and includes amounts recognized in discontinued operations. The total net increase to rental revenues due to the amortization of acquired above- and below-market leases for the six months ended June 30, 2014 and 2013, was approximately $2.3 million and $4.6 million, respectively, and includes amounts recognized in discontinued operations. Revenues relating to lease termination fees are recognized on a straight-line basis amortized from the time that a tenant’s right to occupy the leased space is modified through the end of the revised lease term. For the three months ended June 30, 2014 and 2013, we recognized lease termination fees of approximately $0.7 million and $0.2 million, which includes amounts recognized in discontinued operations. For the six months ended June 30, 2014 and 2013, we recognized lease termination fees of approximately $0.9 million, and $0.3 million which includes amounts recognized in discontinued operations.
Income Taxes	'
	Income Taxes

	We have elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), and have qualified as a REIT since the year ended December 31, 2004. To qualify as a REIT, we must meet a number of organizational and operational requirements, including a requirement that we distribute at least 90% of our REIT taxable income (excluding net capital gains) to our stockholders. As a REIT, we generally will not be subject to federal income tax at the corporate level (except to the extent we distribute less than 100% of our taxable income and/or net taxable capital gains). We generate certain of our taxable income through various taxable REIT subsidiary (“TRS”) entities. The taxable income of our TRS entities is subject to applicable federal, state, and local income and margin taxes.

	As of June 30, 2014, we have deferred tax liabilities of approximately $0.9 million and deferred tax assets, net of related valuation allowances, of less than $0.1 million related to various state taxing jurisdictions. At December 31, 2013, we had deferred tax liabilities of approximately $1.3 million and deferred tax assets, net of related valuation allowances, of less than $0.1 million related to various state taxing jurisdictions.

	We recognize in our financial statements the impact of our tax return positions if it is more likely than not that the tax position will be sustained upon examination (defined as a greater than fifty percent likelihood of being sustained upon audit, based on the technical merits of the tax position). Tax positions that meet the more likely than not threshold are measured at the largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement. We recognize the tax implications of the portion of a tax position that does not meet the more likely than not threshold together with the accrued interest and penalties in the financial statements as a component of the provision for income taxes.
