Commitments and Contingencies

Environmental Matters

Substantially all of the Company's properties and land were subject to Phase I Environmental Assessments and when appropriate Phase II Environmental Assessments (collectively, the “Environmental Assessments”) obtained in contemplation of their acquisition by the Company or obtained by predecessor owners prior to the sale of the property or land to the Company. The Environmental Assessments did not reveal, nor is the Company aware of, any non-compliance with environmental laws, environmental liability or other environmental claim that the Company believes would likely have a material adverse effect on the Company.

Other

As of September 30, 2017, the Company had letter of credit obligations of $6.3 million.

As of September 30, 2017, the Company had 24 buildings under development. These buildings are expected to contain, when completed, a total of 5.9 million square feet of leasable space and represent an anticipated aggregate investment of $560.8 million. At September 30, 2017, development in progress totaled $395.1 million. In addition, as of September 30, 2017, the Company had invested $14.4 million in deferred leasing costs related to these development buildings.

As of September 30, 2017, the Company was committed to $8.3 million in improvements on certain buildings and land parcels.

As of September 30, 2017, the Company was committed to $35.6 million in future land acquisitions. The Company expects to complete these purchases during the year ended December 31, 2017.

As of September 30, 2017, the Company was obligated to pay for tenant improvements not yet completed for a maximum of $26.7 million.

Unconsolidated joint ventures in which the Company holds an interest, and in another case an unrelated third party, have engaged the Company as the developer of certain development properties pursuant to development agreements. The Company agrees, in consideration for a development fee, to be responsible for all aspects of the development of the properties (and, in certain instances, related infrastructure) and to guarantee the timely lien-free completion of construction of the properties and the payment, subject to certain exceptions, of any cost overruns incurred in the development of the properties.

The Company is currently developing four properties for its unconsolidated joint ventures which represent an anticipated aggregate investment by the joint ventures of $976.9 million.

As of September 30, 2017, the Company was also committed to approximately $170.1 million in costs related to its agreement to develop, on a fee basis, an office building and infrastructure improvements for American Water Works in Camden, New Jersey. As of September 30, 2017, $71.8 million of these costs had been incurred.

The Company maintains cash and cash equivalents at financial institutions. The combined account balances at each institution typically exceed FDIC insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company believes the risk is not significant.
