Commitments and Contingencies

Litigation and Claims

In the normal course of business, we are subject to legal actions and other claims. We record losses for specific legal proceedings and claims when we determine that a loss is probable and the amount of loss can be reasonably estimated. Management believes that it is reasonably possible that we could incur losses pursuant to such claims but do not believe such losses would materially affect our financial position, liquidity or our results of operations. Our assessment of the potential outcomes of these matters involves significant judgment and is subject to change based on future developments.

Environmental

We are subject to various Federal, state and local environmental regulations related to our property ownership and operation. We have performed environmental assessments of our properties, the results of which have not revealed any environmental liability that we believe would have a materially adverse effect on our financial position, operations or liquidity.

In connection with a lease and subsequent sale in 2008 and 2010 of three properties in Dayton, New Jersey, we agreed to provide certain environmental indemnifications limited to $19 million in the aggregate. We have insurance coverage in place to mitigate much of any potential future losses that may result from these indemnification agreements.

Tax Incremental Financing Obligation

In August 2010, Anne Arundel County, Maryland issued $30 million in tax incremental financing bonds to third-party investors in order to finance public improvements needed in connection with our project known as National Business Park North. The real estate taxes on increases in assessed value of a development district encompassing National Business Park North are to be transferred to a special fund pledged to the repayment of the bonds. We recognized a $995,000 liability through March 31, 2018 representing our estimated obligation to fund through a special tax any future shortfalls between debt service on the bonds and real estate taxes available to repay the bonds.

Operating Leases

We are obligated as lessee under operating leases (mostly ground leases) with various expiration dates extending to the year 2100. Future minimum rental payments due under the terms of these operating leases as of March 31, 2018 follow (in thousands):



Year Ending December 31,
2018 (1)	$	961
2019	1,267
2020	1,260
2021	1,264
2022	1,151
Thereafter	84,611

Capital Lease

On May 25, 2017, we entered into a ground lease on land under development in Washington, DC for our Stevens Investors, LLC joint venture. The lease has a 99-year term, and we possess an option to purchase the property for one dollar (estimated to occur between 2019 and 2020). Upon inception of the lease, we recorded a $16.1 million capital lease liability on our consolidated balance sheets based on the present value of the future minimum rental payments. Future minimum rental payments due under the term of this lease as of March 31, 2018 follow (in thousands):



Year Ending December 31,
2018 (1)	$	11,628
2020	135
2022	75
Total minimum rental payments	11,838

•	new development and redevelopment obligations of $64.8 million;


•	capital expenditures for operating properties of $45.9 million;


•	third party construction and development of $14.3 million; and


•	other obligations of $2.5 million.
