17.Commitments and Contingencies

Insurance

We maintain general liability insurance with limits of $100.0 million per occurrence and in the aggregate, and property and rental value insurance coverage with limits of $1.0 billion per occurrence, with sub-limits for certain perils such as floods and earthquakes on each of our properties. We also maintain coverage, through our wholly owned captive insurance subsidiary, for a portion of the first loss on the above limits and for both conventional terrorist acts and for nuclear, biological, chemical or radiological terrorism events with limits of $2.0 billion per occurrence. These policies are partially reinsured by third-party insurance providers.

We will continue to monitor the state of the insurance market, and the scope and costs of coverage for acts of terrorism. We cannot anticipate what coverage will be available on commercially reasonable terms in the future. We are responsible for deductibles and losses in excess of the insurance coverage, which could be material.

Our debt, consisting of mortgage loans secured by our properties, a revolving credit facility and term loans, contains customary covenants requiring adequate insurance coverage. Although we believe that we currently have adequate insurance coverage, we may not be able to obtain an equivalent amount of coverage at a reasonable cost in the future. If lenders insist on greater coverage than we can obtain, it could adversely affect our ability to finance or refinance our properties.

Construction Commitments

As of June 30, 2025, we had one asset under construction, Valen (formerly 2000 South Bell Street), and are building a new amenity hub at 2011 Crystal Drive that together, based on our current plans and estimates, require an additional $35.2 million to complete, which we anticipate will be primarily expended over the next year. These capital expenditures are generally due as the work is performed, and we expect to finance them primarily with debt proceeds.

Environmental Matters

Most of our assets have been subject, at some point, to environmental assessments that are intended to evaluate the environmental condition of the subject and surrounding assets. These environmental assessments generally have included a historical review, a public records review, a visual inspection of the site and surrounding assets, visual or historical evidence of underground storage tanks and other features, and the preparation and issuance of a written report. Soil, soil vapor and/or groundwater subsurface testing is conducted at our assets, when necessary, to further investigate any conditions identified by the initial assessment that could reasonably be expected to pose a material concern to the property or result in us incurring material environmental liabilities as a result of redevelopment. The tests may not, however, have included extensive sampling or subsurface investigations. In each case where the environmental assessments have identified conditions requiring remedial actions required by law, we have initiated appropriate actions. The environmental assessments have not revealed any material environmental contamination that we believe would have a material adverse effect on our overall business, financial condition or results of operations, or that have not been anticipated and remediated during site redevelopment as required by law. Nevertheless, there can be no assurance that the identification of new areas of contamination, changes in the extent or known scope of contamination, the discovery of additional sites or changes in cleanup requirements would not result in significant cost to us. Environmental liabilities totaled $17.5 million as of June 30, 2025 and December 31, 2024, and are included in "Other liabilities, net" in our balance sheets.

Legal Proceedings

In November 2023, the District of Columbia filed a lawsuit in the Superior Court of the District of Columbia against RealPage, Inc., a provider of revenue management systems, numerous multifamily rental companies, and 14 owners and/or operators of multifamily housing in the District of Columbia, including JBG Associates, L.L.C., one of our subsidiaries, alleging that the defendants violated the District of Columbia Antitrust Act by unlawfully agreeing to use RealPage, Inc. revenue management systems and sharing sensitive data. While we intend to vigorously defend against this lawsuit, given the current stage of the District of Columbia’s lawsuit, we are unable to predict the outcome or estimate the amount of loss, if any, that may result from the lawsuit. While we do not believe that these proceedings will have a material adverse effect

on our financial condition, we cannot give assurance that the proceedings will not have a material effect on our results of operations or cash flows in the event of a negative outcome.

There are various other legal actions arising in the ordinary course of business. In our opinion, the outcome of such matters is not expected to have a material adverse effect on our financial position, results of operations or cash flows. Our accrual for loss contingencies relating to unresolved legal matters was included in "Other liabilities, net" in the balance sheets. Actual losses may differ materially from amounts recorded and the ultimate outcome of these legal proceedings is generally not yet determinable.

Other

As of June 30, 2025, we had committed tenant-related obligations totaling $34.1 million ($33.9 million related to our consolidated entities and $173,000 related to our unconsolidated real estate ventures at our share). The timing and amounts of payments for tenant-related obligations are uncertain and may only be due upon satisfactory performance of certain conditions.

From time to time, we (or ventures in which we have an ownership interest) have agreed, and may in the future agree with respect to unconsolidated real estate ventures, to (i) guarantee portions of the principal, interest and other amounts in connection with borrowings, (ii) provide customary environmental indemnifications and nonrecourse carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy) in connection with borrowings, or (iii) provide guarantees to lenders and other third parties for the completion and stabilization of development projects. We customarily have agreements with our outside venture partners whereby the partners agree to reimburse the real estate venture or us for their share of any payments made under certain of these guarantees. At times, we also have agreements with certain of our outside venture partners whereby we agree to either indemnify the partners and/or the associated ventures with respect to certain contingent liabilities associated with operating assets or to reimburse our partner for its share of any payments made by them under certain guarantees. Guarantees (excluding environmental) customarily terminate either upon the satisfaction of specified circumstances or repayment of the underlying debt. Amounts that we may be required to pay in future periods in relation to guarantees associated with budget overruns or operating losses are not estimable. As of June 30, 2025, we had no principal payment guarantees related to our unconsolidated real estate ventures.

As of June 30, 2025, we had additional capital commitments totaling $7.2 million related to our investments in real estate-focused technology companies.

​

Additionally, with respect to borrowings of our consolidated entities, we may agree to (i) guarantee portions of the principal, interest and other amounts, (ii) provide customary environmental indemnifications and nonrecourse carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy) or (iii) provide guarantees to lenders, tenants and other third parties for the completion and stabilization of development projects. As of June 30, 2025, we had no debt principal payment guarantees related to our consolidated real estate assets.
