Acquisitions and Dispositions

2015

Acquisitions

The Company completed each of the transactions described below with unaffiliated third parties in arms’ length transactions.

On July 7, 2015, the Company acquired a 0.8 acre parcel of land located at 2100 Market Street in Philadelphia, Pennsylvania for $18.8 million. The Company funded $16.8 million of the purchase price with available corporate funds and the remaining $2.0 million of the purchase price was deferred until the earlier of the commencement of development or 24 months from settlement. The Company accounted for this transaction as an asset acquisition and capitalized a nominal amount of acquisition related costs and other costs as part of land inventory on its consolidated balance sheet. In connection with the purchase agreement, if certain land parcels adjacent to 2100 Market Street are acquired from unaffiliated third parties, the Company may be required to pay additional consideration to the seller of 2100 Market Street. The unaffiliated third parties are not party to this transaction and any land parcels acquired will be acquired in arm’s length transactions. The amount of additional consideration, if any, payable to the seller of 2100 Market Street cannot be determined at this time. The Company has not yet determined the timing and cost of construction for the project as of December 31, 2015.

On June 22, 2015, through a series of transactions with International Business Machines ("IBM"), the Company acquired the remaining 50.0% interest in Broadmoor Austin Associates, consisting of seven office buildings and the 66.0 acre underlying land parcel located in Austin, Texas, for an aggregate purchase price of $211.4 million. The aggregate purchase price includes the carrying amount of our investment in Broadmoor Austin Associates of $66.3 million. The office buildings contain 1,112,236 net rentable square feet of office space and were 100.0% occupied as of June 22, 2015. The Company funded the cost of the acquisition with an aggregate cash payment of $143.8 million, consisting of $81.0 million from available corporate funds and $62.8 million previously held in escrow related to a Section 1031 like-kind exchange. Part of the cash payment was used at closing to repay, at no repayment penalty, the remaining $51.2 million of secured debt. The Company incurred $0.2 million of acquisition related costs that are classified within general and administrative expenses.

The Company previously accounted for its 50.0% non-controlling interest in Broadmoor Austin Associates under the equity method of accounting. As a result of acquiring IBM's remaining 50.0% common interest in Broadmoor Austin Associates, the Company obtained control of Broadmoor Austin Associates and the Company's existing investment balance was remeasured based on the fair value of the underlying properties acquired and the existing distribution provisions under the relevant partnership agreement. As a result, the Company recorded a $0.8 million gain on remeasurement.

The Company has treated its acquisition of the 50.0% ownership interest in Broadmoor Austin Associates as a business combination and allocated the purchase price to the tangible and intangible assets and liabilities. The Company utilized a number of sources in making estimates of fair values for purposes of allocating the purchase price to tangible and intangibles assets acquired and intangible liabilities assumed. The purchase price has been allocated as follows (in thousands):

For the year ended December 31, 2014, $0.2 million of acquisition related costs are included as if the transaction occurred January 1, 2014.

On April 6, 2015, the Company acquired a 0.8 acre parcel of land, located at 25 M Street Southeast, Washington, D.C. for $20.3 million. The Company funded the cost of this acquisition with available corporate funds. The Company capitalized $0.3 million of acquisition related costs and these costs are included as part of land inventory on the Company's consolidated balance sheet. On May 12, 2015, the Company subsequently contributed the land parcel into a newly formed real estate venture known as 25 M Street Holdings, LLC (“25 M Street”), a joint venture between the Company and Jaco 25 M Investors, LLC (“Akridge”), an unaffiliated third party, with the intent to construct a 271,000 square foot Class A office property. The Company holds a 95.0% ownership interest in 25 M Street and Akridge contributed $1.0 million in cash for its 5.0% ownership interest in 25 M Street. The $1.0 million contribution from Akridge was distributed to the Company during 2015. 25 M Street is consolidated within the Company's financial statements. See Note 4, "Investment in Unconsolidated Real Estate Ventures," for further information. As of December 31, 2015, 25 M Street had not finalized development plans and total development costs, or received committed debt financing.

On April 2, 2015, the Company acquired, from an unaffiliated third party, a property located at 618 Market Street in Philadelphia, Pennsylvania, comprised of a 330-space parking garage and 14,404 net rentable square feet for $19.4 million. Although the property is currently fully operational, the Company intends to either redevelop the existing property or demolish and fully develop the property. As of December 31, 2015, we had not yet begun any such development or redevelopment plans. The purchase price includes contingent consideration, recorded at fair value and payable to the seller upon commencement of development, totaling $1.6 million, and cash of $17.8 million.

The Company has treated the acquisition of 618 Market Street as a business combination and allocated the purchase price to the tangible and intangible assets. The Company utilized a number of sources in making estimates of fair values for purposes of allocating the purchase price to tangible and intangible assets acquired. The Company allocated $19.2 million to building, land and improvements and $0.2 million to intangible assets.

The fair value of contingent consideration was determined using a probability weighted discounted cash flow model. The significant inputs to the discounted cash flow model were the discount rate and weighted probability scenarios. As the inputs are unobservable, the Company determined the inputs used to value this liability falls within Level 3 for fair value reporting. As of December 31, 2015, there was no significant changes to the inputs and the liability remains within Level 3 for fair value reporting.

During the fourth quarter of 2015, significant provisions were agreed upon by both the Company and Och Ziff Real Estate and, as a result, the Company determined that the sale of the portfolio was probable and classified these properties as held for sale in accordance with applicable accounting standards for long lived assets. At such date, the carrying value of the properties exceeded the fair value less the anticipated costs of sale. As a result, the Company recognized an impairment loss totaling approximately $45.4 million during the year ended December 31, 2015. The fair value measurement was based on the pricing in the purchase and sale agreement. As the significant inputs to the model are unobservable, the Company determined that the value determined for these real estate investments fall within Level 3 for fair value reporting.

At such date, the carrying value of the properties exceeded the fair value less the anticipated costs of sale. As a result, the Company recognized an impairment loss totaling approximately $0.3 million during the year ended December 31, 2015.

The sales of our equity interests and the fee interests in the properties referenced above do not represent a strategic shift that has a major effect on the Company's operations and financial results. As a result, the operating results of these properties remain classified within continuing operations for all periods presented. See Note 21, "Subsequent Events," for further information regarding these dispositions.

Held for Use Impairment

As of December 31, 2015, the Company evaluated the recoverability of the carrying value of its properties under the undiscounted cash flow model. Based on the analysis, it was determined that due to deteriorating operating results, increased market vacancy and a reduction in management’s intended hold period, the Company would not recover the carrying value of three properties located in our Metropolitan D.C. segment. Accordingly, the Company recorded an impairment charge of $27.5 million at December 31, 2015 reducing the aggregate carrying values of these properties from $40.4 million to their estimated fair values of $12.9 million. The Company determined these impairments based on a discounted cash flow analysis, using a hold period of 10 years and residual capitalization rates and discount rates of 8.0%. The results were compared to indicative pricing in the market. The assumptions used to determine fair value are Level 3 inputs, respectively, in accordance with the fair value hierarchy established by Accounting Standards Codification (ASC) Topic 820, "Fair Value Measurements and Disclosures.”

On June 19, 2013, the Company acquired the remaining ownership interest in the real estate venture known as “Six Tower Bridge” that it did not then already own. See Note 4, “Investments in Unconsolidated Real Estate Ventures,” for further discussion.

Cira Centre

On November 19, 2013, the Company acquired a 0.8 acre land parcel underlying Cira Centre in Philadelphia, Pennsylvania for $24.6 million. The purchase terminates a long term ground lease agreement entered into during the development of Cira Centre. The Company has accounted for the transaction as an asset acquisition. Prior to the acquisition date, the Company recorded ground rent expense on a straight-line basis, resulting in accrued rent liability of $12.1 million. The accounting guidance for leases requires that an asset purchased which was previously subject to an operating lease cannot result in a gain, accordingly, the basis of the acquired land was reduced by the accrued rent liability and no income was recognized at acquisition. The Company capitalized $1.4 million of acquisition related costs as part of the basis in the operating land.

Three Logan Square

On April 25, 2013, the Company exercised its purchase option under the long term ground lease agreement it held through its acquisition of Three Logan Square on August 5, 2010 and acquired the 1.8 acre land parcel underlying Three Logan Square in Philadelphia, Pennsylvania for $20.8 million. The Company has accounted for the transaction as an asset acquisition. A portion of the original purchase price of Three Logan Square was allocated to a below market ground lease intangible asset. As the sum of the purchase price of the land plus the $4.3 million remaining unamortized balance for the intangible asset approximates the fair value of the land as unencumbered by the ground lease, the remaining intangible asset balance was reclassified to land upon exercise of the purchase option. The Company funded the cost of the acquisition with available corporate funds and capitalized $0.1 million of acquisition related costs as part of the basis in the operating land.
