Numerous factors could cause actual future performance, results, and events to differ materially from those indicated in the forward-looking statements, including, among others: global market and general economic conditions, including actual and potential tariffs and periods of heightened inflation, and their effect on our liquidity and financial conditions and those of our tenants; adverse economic or real estate conditions generally, and specifically, in the States of California, Texas, and Washington; risks associated with our investment in real estate assets, which are illiquid, and with trends in the real estate industry; defaults on or non-renewal of leases by tenants; any significant downturn in tenants' businesses, including bankruptcy, lack of liquidity or lack of funding, and the impact labor disruptions or strikes, such as episodic strikes in the media industry, may have on our tenants' businesses; our ability to re-lease property at or above current market rates; reduced demand for office space, including as a result of remote working and flexible working arrangements that allow work from remote locations other than an employer's office premises; costs to comply with government regulations, including environmental remediation; the availability of cash for distribution and debt service, and exposure to risk of default under debt obligations; increases in interest rates and our ability to manage interest rate exposure; changes in interest rates and the availability of financing on attractive terms or at all, which may adversely impact our future interest expense and our ability to pursue development, redevelopment, and acquisition opportunities and refinance existing debt; a decline in real estate asset valuations, which may limit our ability to dispose of assets at attractive prices, or obtain or maintain debt financing, and which may result in write-offs or impairment charges; significant competition, which may decrease the occupancy and rental rates of properties; potential losses that may not be covered by insurance; the ability to successfully complete acquisitions and dispositions on announced terms; the ability to successfully operate acquired, developed, and redeveloped properties; the ability to successfully complete development and redevelopment projects on schedule and within budgeted amounts; delays or refusals in obtaining all necessary zoning, land use, and other required entitlements, governmental permits and authorizations for our development and redevelopment properties; increases in anticipated capital expenditures, tenant improvement, and/or leasing costs; defaults on leases for land on which some of our properties are located; adverse changes to, or enactment or implementations of, tax laws or other applicable laws, regulations, or legislation, as well as business and consumer reactions to such changes; risks associated with joint venture investments, including our lack of sole decision-making authority, our reliance on co-venturers' financial condition, and disputes between us and our co-venturers; environmental uncertainties and risks related to natural disasters; risks associated with climate change and our sustainability strategies, and our ability to achieve our sustainability goals; and our ability to maintain our status as a REIT. These factors are not exhaustive and additional factors could adversely affect our business and financial performance.
