Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Guarantees	Commitments, Contingencies and Guarantees Legal Proceedings From time to time, we are party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of our business. Excluding ordinary, routine litigation incidental to our business, we are not currently a party to any legal proceedings that we believe would reasonably be expected to have a materially adverse effect on our business, financial condition or results of operations. The Landmark Residences (Formerly Barrington Plaza) In May 2023, we used a state law, the Ellis Act, to begin moving tenants out of the buildings in order to complete fire and life safety retrofits. We are appealing a ruling by a trial court in Santa Monica that the Ellis Act wasn’t the proper avenue for removing those tenants. We do not expect the ruling to have a meaningful impact on the anticipated timing, cost, or ultimate plans for The Landmark Residences property, and continue to coordinate with the City of Los Angeles to comply with its order to sprinkler The Landmark Residences property and to complete other fire life safety work. We are currently in litigation with the insurance providers in 2020 for The Landmark Residences to recover certain costs associated with reconstruction. Concentration of Risk Tenant Receivables We are subject to credit risk with respect to our tenant receivables and deferred rent receivables related to our tenant leases. Our tenants' ability to honor the terms of their respective leases remains dependent upon economic, regulatory and social factors. We seek to minimize our credit risk from our tenant leases by (i) targeting smaller, more affluent office tenants, from a diverse mix of industries, (ii) performing credit evaluations of prospective tenants and (iii) obtaining security deposits or letters of credit from our tenants. For each of the nine month periods ended September 30, 2025 and 2024, no tenant accounted for more than 10% of our total revenues. Geographic Risk All of our properties, including our consolidated JVs' properties, are located in Los Angeles County, California and Honolulu, Hawaii, and we are therefore susceptible to adverse economic and regulatory developments, as well as natural disasters, in those markets. Derivative Counterparty Credit Risk We are subject to credit risk with respect to our derivative counterparties. We do not post or receive collateral with respect to our derivative transactions. Our derivative contracts do not provide for right of offset between derivative contracts. See Note 10 for the details of our derivative contracts. We seek to minimize our credit risk by entering into agreements with a variety of counterparties with investment grade ratings. Cash Balances We have significant cash balances invested in a variety of short-term money market funds that are intended to preserve principal value and maintain a high degree of liquidity while providing current income. These investments are not insured against loss of principal and there is no guarantee that our investments in these funds will be redeemable at par value. We also have significant cash balances in bank accounts with high quality financial institutions with investment grade ratings. Interest bearing bank accounts at each U.S. banking institution are insured by the FDIC up to $250 thousand. Asset Retirement Obligations Conditional asset retirement obligations represent a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement is conditional on a future event that may or may not be within our control. A liability for a conditional asset retirement obligation must be recorded if the fair value of the obligation can be reasonably estimated. Environmental site assessments have identified thirty-three buildings in our Total Portfolio which contain asbestos, and would have to be removed in compliance with applicable environmental regulations if these properties are demolished or undergo major renovations. As of September 30, 2025, the obligations to remove the asbestos from properties which are currently undergoing major renovations, or that we plan to renovate in the future, are not material to our consolidated financial statements. As of September 30, 2025, the obligations to remove the asbestos from our other properties have indeterminable settlement dates, and we are unable to reasonably estimate the fair value of the associated conditional asset retirement obligations. Contractual Commitments As of September 30, 2025, we had an aggregate remaining contractual commitment for development projects, repositioning projects, capital expenditure projects and tenant improvements of approximately $287.4 million. Loan Guarantees In November 2023, we signed a guarantee for the $175.0 million consolidated JV loan which guarantees the portion of the loan principal that would need to be paid down to meet the minimum debt yield in the loan agreement. The loan matures in April 2029. The guarantee will remain in effect until either the guarantee obligation or the loan is paid in full. As of September 30, 2025, we estimate the risk of loss for this guarantee to be low. See Note 8 for more information regarding our debt.
