Subsequent Events [Abstract]
Subsequent Events	22. Subsequent Events On February 1, 2024, we, together with our joint venture partner, modified and extended the existing mortgage loan at One Market Plaza, a 1.6 million square-foot two-building trophy asset in San Francisco, California. The existing $975,000,000 loan, which bore interest at a fixed rate of 4.03%, was scheduled to mature on February 6, 2024. In connection with the modification, the loan balance was reduced to $850,000,000, following a $125,000,000 paydown by the joint venture, of which our 49.0% share was $61,250,000. The modified loan bears interest at a fixed rate of 4.08%, matures in February 2027 and has an option to extend for an additional year, subject to certain conditions.
