Summary of Significant Accounting Policies	Jun. 30, 2017
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The condensed consolidated financial statements include the financial position and results of operations of the Company and its consolidated subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for the fair presentation of the financial condition and results of operations for the interim periods presented. The accompanying condensed consolidated financial statements were prepared in accordance with the requirements for interim financial information. Accordingly, these interim financial statements have not been audited and exclude certain disclosures required for annual financial statements. Also, the operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These interim financial statements should be read in conjunction with the audited consolidated financial statements of the Company included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed. Such estimates are based on management’s historical experience and best judgment after considering past, current and expected events and economic conditions. Actual results could differ from management’s estimates. Significant Accounting Policies The accompanying condensed consolidated financial statements were prepared on the basis of the accounting principles described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Recent Accounting Pronouncements On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued a new standard that provides a single, comprehensive model for recognizing revenue from contracts with customers. While the new standard does not supersede the guidance on accounting for leases, it could change the way the Company recognizes revenue from construction and development contracts with third party customers. The new standard will be effective for the Company on January 1, 2018. The Company plans to adopt the new standard using the full retrospective method. A substantial portion of the Company's revenue consists of rental revenues from leasing arrangements, such as base rent, which is specifically excluded from the revenue guidance. Non-lease components, such as tenant reimbursements for common area maintenance, will be subject to the revenue guidance. Management is currently evaluating the potential impact of the new revenue standard on the Company’s consolidated financial statements. The Company does not expect the new standard to have a material impact on the measure and recognition of gains and losses on the sale of properties. On February 25, 2016, the FASB issued a new lease standard that requires lessees to recognize most leases in their balance sheets as lease liabilities with corresponding right-of-use assets. The new standard also makes targeted changes to lessor accounting. The new standard will be effective for the Company on January 1, 2019 and requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application with an option to use certain transition relief. Management is currently evaluating the potential impact of the new lease standard on the Company’s consolidated financial statements. On March 30, 2016, the FASB issued new guidance that will change the accounting for certain aspects of share-based payments to employees. Entities will be required to recognize the income tax effects of awards in the income statement when the awards vest or are settled, and allows the Company to account for forfeitures as they occur. The new guidance became effective for the Company on January 1, 2017. The Company adopted the guidance on January 1, 2017 and it did not have a material impact on the Company’s consolidated financial statements. On August 26, 2016, the FASB issued new guidance that addresses eight classification issues related to the statement of cash flows. Early adoption is permitted, including adoption in an interim period. This guidance should be applied retrospectively to each period presented. This new guidance will be effective for the Company on January 1, 2018. Management is currently evaluating the potential impact of the new guidance on the Company’s consolidated financial statements. On February 22, 2017, the FASB issued new guidance that clarifies the scope and application of guidance on sales or transfers of nonfinancial assets and in substance nonfinancial assets to customers, including partial sales. The new guidance applies to all nonfinancial assets, including real estate, and defines an in substance nonfinancial asset. The new guidance will be effective for the Company on January 1, 2018, with early adoption permitted. Management is currently evaluating the potential impact of the new revenue standard on the Company’s consolidated financial statements.

Segment Reporting [Abstract]

Segments

Net operating income (segment revenues minus segment expenses) is the measure used by the Company’s chief operating decision-maker to assess segment performance. Net operating income is not a measure of operating income or cash flows from operating activities as measured by GAAP and is not indicative of cash available to fund cash needs. As a result, net operating income should not be considered an alternative to cash flows as a measure of liquidity. Not all companies calculate net operating income in the same manner. The Company considers net operating income to be an appropriate supplemental measure to net income because it assists both investors and management in understanding the core operations of the Company’s real estate and construction businesses.

Net operating income of the Company’s reportable segments for the three and six months ended June 30, 2017 and 2016 was as follows (in thousands):

Equity Method Investment	Equity Method Investment City Center On February 25, 2016, the Company acquired a 37% interest in Durham City Center II, LLC (“City Center”) for purposes of developing a 22-story mixed use tower in Durham, North Carolina. As of June 30, 2017 and December 31, 2016, the Company has invested $11.0 million and $10.3 million, respectively, in City Center. The Company has agreed to guarantee 37% of the construction loan for City Center; however, the loan is collateralized by 100% of the assets of City Center. As of June 30, 2017, $10.8 million has been drawn against the construction loan, of which $5.5 million is attributable to the Company's portion of the loan. As of June 30, 2017 and December 31, 2016, the difference between the carrying value of the Company’s initial investment in City Center and the amount of underlying equity was immaterial. For the three and six months ended June 30, 2017 and 2016, City Center did not have any operating activity, and therefore the Company did not receive any dividends or allocated income. Based on the terms of City Center’s operating agreement, the Company has concluded that City Center is a variable interest entity, and that the Company holds a variable interest. The Company does not have the power to direct the activities of the project that most significantly impact its performance. Accordingly, the Company is not the project’s primary beneficiary and, therefore, does not consolidate City Center in its consolidated financial statements.

Receivables [Abstract]
Notes Receivable	Notes Receivable Point Street Apartments On October 15, 2015, the Company agreed to invest up to $28.2 million in the Point Street Apartments project in the Harbor Point area of Baltimore, Maryland. Point Street Apartments is an estimated $92 million development project with plans for a 17-story building comprised of 289 residential units and 18,000 square feet of street-level retail space. Beatty Development Group (“BDG”) is the developer of the project and has engaged the Company to serve as construction general contractor. Point Street Apartments is scheduled to open in the fourth quarter of 2017; however, management can provide no assurances that Point Street Apartments will open on the anticipated timeline or be completed at the anticipated cost. BDG secured a senior construction loan of up to $67.0 million to fund the development and construction of Point Street Apartments on November 10, 2016. The Company has agreed to guarantee $25.0 million of the senior construction loan in exchange for the option to purchase up to an 88% controlling interest in Point Street Apartments upon completion of the project as follows: (i) an option to purchase a 79% indirect interest in Point Street Apartments for $27.3 million, exercisable within one year from the project’s completion (the “First Option”) and (ii) provided that the Company has exercised the First Option, an option to purchase an additional 9% indirect interest in Point Street Apartments for $3.1 million, exercisable within 27 months from the project’s completion (the “Second Option”). The Company currently has a $2.1 million letter of credit for the guarantee of the senior construction loan. The Company’s investment in the Point Street Apartments project is in the form of a loan pursuant to which BDG may borrow up to $28.2 million (the “BDG loan”). Interest on the BDG loan accrues at 8.0% per annum and matures on the earliest of: (i) November 1, 2018, which may be extended by BDG under two one-year extension options, (ii) the maturity date or earlier termination of the senior construction loan or (iii) the date the Company exercises the Second Option as described further below. In the event the Company exercises the First Option, BDG is required to pay down the outstanding BDG loan in full, with the difference between the BDG loan and $28.2 million applied to the senior construction loan. In the event the Company exercises the Second Option, BDG is required to simultaneously repay any remaining amounts outstanding under the BDG loan, with any excess proceeds received from the exercise of the Second Option applied against the senior construction loan. In the event the Company does not exercise either the First Option or the Second Option, the interest rate on the BDG loan will automatically be reduced to the interest rate on the senior construction loan for the remaining term of the BDG loan. As of June 30, 2017 and December 31, 2016, the Company had funded $21.5 million and $20.6 million, respectively, under the BDG loan. During the three months ended June 30, 2017 and 2016, the Company recognized $0.4 million and $0.3 million, respectively, of interest income on the BDG loan. During the six months ended June 30, 2017 and 2016, the Company recognized $0.8 million and $0.4 million, respectively, of interest income on the BDG loan. BDG is current on the BDG loan. Management has concluded that this entity is a VIE. Because BDG is the developer of Point Street Apartments, the Company does not have the power to direct the activities of the project that most significantly impact its performance, nor is the Company the party most closely associated with the project. Therefore, the Company is not the project's primary beneficiary and does not consolidate the project in its consolidated financial statements. Annapolis Junction On April 21, 2016, the Company entered into a note receivable with a maximum balance of $48.1 million in connection with the Annapolis Junction residential component of the Annapolis Junction Town Center project in Maryland (“Annapolis Junction”). Annapolis Junction is an estimated $102.0 million mixed-use development project with plans for 416 residential units, 17,000 square feet of retail space and a 150-room hotel. Annapolis Junction Apartments Owner, LLC (“AJAO”) is the developer of the residential component and has engaged the Company to serve as construction general contractor for the residential component. Annapolis Junction is scheduled to open in the third quarter of 2017; however, management can provide no assurances that Annapolis Junction will open on the anticipated timeline or at the anticipated cost. AJAO secured a senior construction loan of up to $60.0 million to fund the development and construction of Annapolis Junction's residential component on September 30, 2016. The Company has agreed to guarantee up to $25.0 million of the senior construction loan in exchange for the option to purchase up to an 88% controlling interest in Annapolis Junction upon completion of the project as follows: (i) an option to purchase an 80% indirect interest in Annapolis Junction's residential component for the lesser of the seller’s budgeted or actual cost, exercisable within one year from the project’s completion (the “First Option”) and (ii) provided that the Company has exercised the First Option, an option to purchase an additional 8% indirect interest in Annapolis Junction for the lesser of the seller’s actual or budgeted cost, exercisable within 27 months from the project’s completion (the “Second Option”). The Company’s investment in the Annapolis Junction project is in the form of a loan under which AJAO may borrow up to $48.1 million, including a $6.0 million interest reserve (the “AJAO loan”). Interest on the AJAO loan accrues at 10.0% per annum and matures on the earliest of: (i) December 21, 2020, which may be extended by AJAO under two one-year extension options, (ii) the maturity date or earlier termination of the senior construction loan or (iii) the date the Company exercises the Second Option as described further below. In the event that the Company exercises the First Option, AJAO is required to simultaneously pay down both the senior construction loan and the AJAO loan by 80%, at which time the interest rate on the AJAO loan will automatically be reduced to the interest rate on the senior construction loan. In the event the Company exercises the Second Option, AJAO is required to simultaneously repay any remaining amounts outstanding under the AJAO loan, with any excess proceeds received from the exercise of the Second Option applied against the remaining balance of the senior construction loan. In the event that the Company does not exercise either the First Option or the Second Option, the interest rate on the AJAO loan will automatically be reduced to the interest rate on the senior construction loan for the remaining term of the AJAO loan. As of June 30, 2017 and December 31, 2016, the Company had funded $40.9 million and $38.9 million, respectively, on the AJAO loan. During the three months ended June 30, 2017 and 2016, the Company recognized $1.0 million and $0.5 million, respectively, of interest income on the AJAO loan. During the six months ended June 30, 2017 and 2016, the Company recognized $2.0 and $0.5 million, respectively, of interest income on the AJAO loan. AJAO is current on the AJAO loan. Management has concluded that this entity is a VIE. Because AJAO is the developer of Annapolis Junction, the Company does not have the power to direct the activities of the project that most significantly impact its performance, nor is the Company the party most closely associated with the project. Therefore, the Company is not the project's primary beneficiary and does not consolidate the project in its consolidated financial statements. Decatur On May 15, 2017, the Company invested in the development of a $34 million Whole Foods anchored center located in Decatur, Georgia. The Company's investment is in the form of a mezzanine loan of up to $21.8 million to the developer, North Decatur Square Holdings, LLC ("NDSH"). The mezzanine loan bears interest at an annual rate of 15%. The note matures on the earliest of (i) May 15, 2022, (ii) the maturity of the senior construction loan, (iii) the sale of NDSH or (iv) the sale of the center. NDSH is current on this loan. As of June 30, 2017, the Company had funded $10.8 million on this loan. During the three months ended June 30, 2017, the Company recognized $0.2 million of interest income on this loan.

Derivative Financial Instruments

The Company may enter into interest rate derivative contracts to manage exposure to interest rate risks. The Company does not use derivative financial instruments for trading or speculative purposes. Derivative financial instruments are recognized at fair value and presented within other assets and liabilities in the condensed consolidated balance sheets. Gains and losses resulting from changes in the fair value of derivatives that are neither designated nor qualify as hedging instruments are recognized within the change in fair value of interest rate derivatives in the condensed consolidated statements of income. For derivatives that qualify as cash flow hedges, the effective portion of the gain or loss is reported as a component of other comprehensive loss and reclassified into earnings in the periods during which the hedged forecasted transaction affects earnings.

On February 1, 2017, the North Point Center Note 5 was paid in full, which terminated the interest rate swap agreement associated with the note. The loss on the interest rate swap agreement was not significant.

Equity [Abstract]
Equity	Equity Stockholders’ Equity On May 4, 2016, the Company commenced an at-the-market continuous equity offering program (the “ATM Program”) through which the Company could, from time to time, issue and sell shares of its common stock having an aggregate offering price of up to $75.0 million. During the six months ended June 30, 2017, the Company issued and sold an aggregate of 450,690 shares of common stock at a weighted average price of $14.08 per share under the ATM Program, receiving net proceeds, after offering costs and commissions, of $6.2 million. On May 12, 2017, the Company completed an underwritten public offering of 6.9 million shares of common stock at a public offering price of $13.00 per share, which resulted in net proceeds after offering costs and commissions of $85.3 million. As of June 30, 2017 and December 31, 2016, the Company’s authorized capital was 500 million shares of common stock and 100 million shares of preferred stock. The Company had 44,932,241 and 37,490,361 shares of common stock issued and outstanding as of June 30, 2017 and December 31, 2016, respectively. No shares of preferred stock were issued and outstanding as of June 30, 2017 or December 31, 2016. Redeemable Noncontrolling Interests The noncontrolling interest holder of Johns Hopkins Village has the option to redeem the 20% noncontrolling interest in that entity (the "Put Option"). Currently, the Put Option may be redeemed for $2.0 million in cash or the equivalent amount in Class A units of limited partnership interest in the Operating Partnership ("Class A Units"), which is in the holder's control. Upon the first anniversary of the certificate of occupancy, which is expected to occur in August 2017, the Put Option may be settled for the fair value of the 20% noncontrolling interest in Johns Hopkins Village, as determined by appraised value. Because the method of the Put Option's redemption is outside of the Company's control, it has been included in temporary equity. If the Put Option is exercised for redemption in the form of Class A Units, the noncontrolling interest will be reclassed into permanent equity. Noncontrolling Interests As of June 30, 2017 and December 31, 2016, the Company held a 71.6% and 68.1% interest, respectively, in the Operating Partnership. The Company is the primary beneficiary of the Operating Partnership as it has the power to direct the activities of the Operating Partnership and the rights to absorb 71.6% of the net income of the Operating Partnership. As the primary beneficiary, the Company consolidates the financial position and results of operations of the Operating Partnership. Noncontrolling interests in the Company represent units of limited partnership interest in the Operating Partnership not held by the Company. The Company's financial position and results of operations are the same as those of the Operating Partnership. The noncontrolling interest for the consolidated entities under development or construction (see Note 1) was zero as of June 30, 2017 and December 31, 2016. As of June 30, 2017, there were 16,570,512 Class A Units not held by the Company. As partial consideration for the acquisition of Columbus Village, the Operating Partnership issued 1,000,000 Class B Units on July 10, 2015 and issued 275,000 Class C Units on January 10, 2017. The Class B Units were automatically converted to Class A Units on July 10, 2017. Subject to the occurrence of certain events, the Class C Units will not earn or accrue distributions until January 10, 2018, at which time they automatically will convert into Class A Units. On January 10, 2017, the Operating Partnership issued 68,691 Class A Units to acquire the remaining 20% interest in the Town Center Phase VI project. Common Stock Dividends and Class A Unit Distributions On January 5, 2017, the Company paid cash dividends of $6.7 million to common stockholders and the Operating Partnership paid cash distributions of $3.0 million to holders of Class A Units. On April 6, 2017, the Company paid cash dividends of $7.2 million to common stockholders and the Operating Partnership paid cash distributions of $3.2 million to holders of Class A Units.

As of June 30, 2017, there were 1,085,610 shares available for issuance under the Amended Plan. During the six months ended June 30, 2017, the Company granted an aggregate of 112,097 shares of restricted stock to employees and non-employee directors with a weighted average grant date fair value of $14.05 per share. Employee restricted stock awards generally vest over a period of two years: one-third immediately on the grant date and the remaining two-thirds in equal amounts on the first two anniversaries following the grant date, subject to continued service to the Company. Non-employee director restricted stock awards vest either immediately upon grant or over a period of one year, subject to continued service to the Company. During the six months ended June 30, 2017, the Company issued performance-based awards in the form of restricted stock units to certain employees. The performance period for these awards is three years, with a required two-year service period immediately following the expiration of the performance period.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Fair value measurements are based on assumptions that market participants would use in pricing an asset or a liability. The hierarchy for inputs used in measuring fair value is as follows:

Level 1—quoted prices in active markets for identical assets or liabilities

Level 2—observable inputs other than quoted prices in active markets for identical assets and liabilities

Level 3—unobservable inputs

Except as disclosed below, the carrying amounts of the Company’s financial instruments approximate their fair value. Financial assets and liabilities whose fair values are measured on a recurring basis using Level 2 inputs consist of interest rate swaps and caps. The Company measures the fair values of these assets and liabilities based on prices provided by independent market participants that are based on observable inputs using market-based valuation techniques.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. For disclosure purposes, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.

The fair value of the Company’s long term debt is sensitive to fluctuations in interest rates. Discounted cash flow analysis based on Level 2 inputs is generally used to estimate the fair value of the Company’s long term debt. Considerable judgment is used to estimate the fair value of financial instruments. The estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments.

The carrying amounts and fair values of the Company’s financial instruments, all of which are based on Level 2 inputs, as of June 30, 2017 and December 31, 2016, were as follows (in thousands):



	June 30, 2017				December 31, 2016

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings The Company is from time to time involved in various disputes, lawsuits, warranty claims, environmental and other matters arising in the ordinary course of business. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters. The Company currently is a party to various legal proceedings. Management accrues a liability for litigation if an unfavorable outcome is determined to be probable and the amount of loss can be reasonably estimated. If an unfavorable outcome is determined to be probable and a range of loss can be reasonably estimated, management accrues the best estimate within the range; however, if no amount within the range is a better estimate than any other, the minimum amount within the range is accrued. Legal fees related to litigation are expensed as incurred. Management does not believe that the ultimate outcome of these matters, either individually or in the aggregate, could have a material adverse effect on the Company’s financial position or results of operations; however, litigation is subject to inherent uncertainties. Under the Company’s leases, tenants are typically obligated to indemnify the Company from and against all liabilities, costs and expenses imposed upon or asserted against it as owner of the properties due to certain matters relating to the operation of the properties by the tenant. Commitments The Company has a bonding line of credit for its general contracting construction business and is contingently liable under performance and payment bonds, bonds for cancellation of mechanics liens and defect bonds. Such bonds collectively totaled $43.0 million and $40.5 million as of June 30, 2017 and December 31, 2016, respectively. The Operating Partnership has entered into standby letters of credit using the available capacity under the senior unsecured credit facility.

Letters of credit generally are available for draw down in the event the Company does not perform. As of June 30, 2017 and December 31, 2016, the Operating Partnership had total outstanding letters of credit of $4.1 million and $4.1 million, respectively. The amounts outstanding at June 30, 2017 and December 31, 2016 include $2.0 million relating to construction projects and a $2.1 million letter of credit related to the guarantee on the Point Street Apartments senior construction loan.

Summary of Significant Accounting Policies (Policies)	Jun. 30, 2017
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The condensed consolidated financial statements include the financial position and results of operations of the Company and its consolidated subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for the fair presentation of the financial condition and results of operations for the interim periods presented. The accompanying condensed consolidated financial statements were prepared in accordance with the requirements for interim financial information. Accordingly, these interim financial statements have not been audited and exclude certain disclosures required for annual financial statements. Also, the operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These interim financial statements should be read in conjunction with the audited consolidated financial statements of the Company included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed. Such estimates are based on management’s historical experience and best judgment after considering past, current and expected events and economic conditions. Actual results could differ from management’s estimates.
Significant Accounting Policies	Significant Accounting Policies The accompanying condensed consolidated financial statements were prepared on the basis of the accounting principles described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.
Recent Accounting Pronouncements	Recent Accounting Pronouncements On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued a new standard that provides a single, comprehensive model for recognizing revenue from contracts with customers. While the new standard does not supersede the guidance on accounting for leases, it could change the way the Company recognizes revenue from construction and development contracts with third party customers. The new standard will be effective for the Company on January 1, 2018. The Company plans to adopt the new standard using the full retrospective method. A substantial portion of the Company's revenue consists of rental revenues from leasing arrangements, such as base rent, which is specifically excluded from the revenue guidance. Non-lease components, such as tenant reimbursements for common area maintenance, will be subject to the revenue guidance. Management is currently evaluating the potential impact of the new revenue standard on the Company’s consolidated financial statements. The Company does not expect the new standard to have a material impact on the measure and recognition of gains and losses on the sale of properties. On February 25, 2016, the FASB issued a new lease standard that requires lessees to recognize most leases in their balance sheets as lease liabilities with corresponding right-of-use assets. The new standard also makes targeted changes to lessor accounting. The new standard will be effective for the Company on January 1, 2019 and requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application with an option to use certain transition relief. Management is currently evaluating the potential impact of the new lease standard on the Company’s consolidated financial statements. On March 30, 2016, the FASB issued new guidance that will change the accounting for certain aspects of share-based payments to employees. Entities will be required to recognize the income tax effects of awards in the income statement when the awards vest or are settled, and allows the Company to account for forfeitures as they occur. The new guidance became effective for the Company on January 1, 2017. The Company adopted the guidance on January 1, 2017 and it did not have a material impact on the Company’s consolidated financial statements. On August 26, 2016, the FASB issued new guidance that addresses eight classification issues related to the statement of cash flows. Early adoption is permitted, including adoption in an interim period. This guidance should be applied retrospectively to each period presented. This new guidance will be effective for the Company on January 1, 2018. Management is currently evaluating the potential impact of the new guidance on the Company’s consolidated financial statements. On February 22, 2017, the FASB issued new guidance that clarifies the scope and application of guidance on sales or transfers of nonfinancial assets and in substance nonfinancial assets to customers, including partial sales. The new guidance applies to all nonfinancial assets, including real estate, and defines an in substance nonfinancial asset. The new guidance will be effective for the Company on January 1, 2018, with early adoption permitted. Management is currently evaluating the potential impact of the new revenue standard on the Company’s consolidated financial statements.
Derivative Financial Instruments	Derivative Financial Instruments The Company may enter into interest rate derivative contracts to manage exposure to interest rate risks. The Company does not use derivative financial instruments for trading or speculative purposes. Derivative financial instruments are recognized at fair value and presented within other assets and liabilities in the condensed consolidated balance sheets. Gains and losses resulting from changes in the fair value of derivatives that are neither designated nor qualify as hedging instruments are recognized within the change in fair value of interest rate derivatives in the condensed consolidated statements of income. For derivatives that qualify as cash flow hedges, the effective portion of the gain or loss is reported as a component of other comprehensive loss and reclassified into earnings in the periods during which the hedged forecasted transaction affects earnings.
Fair Value of Financial Instruments	Fair value measurements are based on assumptions that market participants would use in pricing an asset or a liability. The hierarchy for inputs used in measuring fair value is as follows: Level 1—quoted prices in active markets for identical assets or liabilities Level 2—observable inputs other than quoted prices in active markets for identical assets and liabilities Level 3—unobservable inputs Except as disclosed below, the carrying amounts of the Company’s financial instruments approximate their fair value. Financial assets and liabilities whose fair values are measured on a recurring basis using Level 2 inputs consist of interest rate swaps and caps. The Company measures the fair values of these assets and liabilities based on prices provided by independent market participants that are based on observable inputs using market-based valuation techniques. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. For disclosure purposes, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. The fair value of the Company’s long term debt is sensitive to fluctuations in interest rates. Discounted cash flow analysis based on Level 2 inputs is generally used to estimate the fair value of the Company’s long term debt. Considerable judgment is used to estimate the fair value of financial instruments. The estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments.
Legal Proceedings	Legal Proceedings The Company is from time to time involved in various disputes, lawsuits, warranty claims, environmental and other matters arising in the ordinary course of business. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters. The Company currently is a party to various legal proceedings. Management accrues a liability for litigation if an unfavorable outcome is determined to be probable and the amount of loss can be reasonably estimated. If an unfavorable outcome is determined to be probable and a range of loss can be reasonably estimated, management accrues the best estimate within the range; however, if no amount within the range is a better estimate than any other, the minimum amount within the range is accrued. Legal fees related to litigation are expensed as incurred. Management does not believe that the ultimate outcome of these matters, either individually or in the aggregate, could have a material adverse effect on the Company’s financial position or results of operations; however, litigation is subject to inherent uncertainties. Under the Company’s leases, tenants are typically obligated to indemnify the Company from and against all liabilities, costs and expenses imposed upon or asserted against it as owner of the properties due to certain matters relating to the operation of the properties by the tenant.
