Subsequent Events [Abstract] |
Subsequent Events | 18. Subsequent Events On January 18, 2022, a joint venture in which the Company has a 50% interest, commenced the redevelopment of 651 Gateway located in South San Francisco, California. 651 Gateway is an approximately 293,000 net rentable square foot office building that will be converted to life sciences space. The project is expected to be completed in late 2023. On January 28, 2022 and February 1, 2022, Boston Properties, Inc. issued an aggregate of 33,091 shares of restricted common stock and Boston Properties Limited Partnership issued an aggregate of 249,873 LTIP Units under the 2021 Plan to certain employees of Boston Properties, Inc. On February 1, 2022, Boston Properties, Inc.’s Compensation Committee approved the 2022 Multi-Year Long-Term Incentive Program (the “2022 MYLTIP”) awards under the 2021 Plan to certain officers and employees of Boston Properties, Inc. Earned awards will range from zero to a maximum of 254,061 LTIP Units depending on Boston Properties, Inc.’s relative and absolute TSR performance with a target of approximately 127,031 LTIP Units. Under ASC 718, the 2022 MYLTIP awards have an aggregate value of approximately $17.3 million. On February 2, 2022, a joint venture in which the Company has a 55% interest recommenced the development of Platform 16, a Class A office project located in San Jose, California, that is expected to be approximately 1.1 million square feet upon completion. The first phase of the development project will include the construction of an approximately 390,000 square foot Class A creative office building and a below-grade parking garage, which are expected to be completed in early 2025. On February 4, 2022, the measurement period for the Company’s 2019 MYLTIP awards ended and, based on Boston Properties, Inc.’s relative TSR performance, the final payout was determined to be 69.0% of target, or an aggregate of approximately $8.6 million (after giving effect to employee separations). As a result, an aggregate of 144,043 2019 MYLTIP Units that had been previously granted were automatically forfeited.
