Subsequent Events [Abstract] |
Subsequent Events | 16. Subsequent Events On January 4, 2023, BPLP entered into the 2023 Unsecured Term Loan, which provided for a single borrowing of up to $1.2 billion. Under the credit agreement, BPLP may, at any time prior to the maturity date, increase total commitments by up to an additional $300.0 million in aggregate principal amount by increasing the existing 2023 Unsecured Term Loan or incurring one or more additional term loans, in each case, subject to syndication of the increase and other conditions. The 2023 Unsecured Term Loan matures on May 16, 2024, with one 12-month extension option, subject to customary conditions. Upon entry into the credit agreement, BPLP exercised its option to draw $1.2 billion under the 2023 Unsecured Term Loan, a portion of which was used to repay in full the 2022 Unsecured Term Loan, which was scheduled to mature on May 16, 2023 (see Note 7). At BPLP’s option, loans under the 2023 Unsecured Term Loan will bear interest at a rate per annum equal to (1) a base rate equal to the greatest of (a) the Federal Funds rate plus 1/2 of 1%, (b) the administrative agent’s prime rate, (c) Term SOFR for a one-month period plus 1.00%, and (d) 1.00%, in each case, plus a margin ranging from 0 to 60 basis points based on BPLP’s credit rating; or (2) a rate equal to adjusted Term SOFR with a one-month period plus a margin ranging from 75 to 160 basis points based on BPLP’s credit rating. Based on BPLP’s credit rating upon entry into the credit agreement, the base rate margin is 0 basis points and the Term SOFR margin is 0.85%. The 2023 Unsecured Term Loan currently bears interest at a rate equal to adjusted Term SOFR plus 0.85%. On January 5, 2023, the Company commenced the development of 290 Binney Street, an approximately 566,000 net rentable square feet laboratory/life sciences project in Cambridge, Massachusetts. Concurrent with the commencement of this project, the Company began demolition of the existing Kendall Center Blue Parking Garage to support the development of this project. 290 Binney Street is 100% pre-leased to AstraZeneca (See Note 3). On January 30, 2023, the Company commenced the redevelopment of 300 Binney Street at Kendall Center in Cambridge, Massachusetts. 300 Binney Street consisted of an approximately 195,000 net rentable square foot premier workplace that is being redeveloped into approximately 240,000 net rentable square feet of laboratory/life sciences space. The project is 100% pre-leased to a life sciences organization. On January 31, 2023, the Company acquired a 50% interest in a joint venture that owns 13100 and 13150 Worldgate Drive located in Herndon, Virginia for a gross purchase price of approximately $17.0 million. The acquisition was completed with available cash. 13100 and 13150 Worldgate Drive consists of two vacant office buildings aggregating approximately 350,000 rentable square feet and a 1,200-space structured parking deck situated on a 10-acre site. The joint venture intends to redevelop the property for residential use. There can be no assurance that the joint venture will commence the development on the terms currently contemplated or at all. On January 25, 2023, BXP’s Compensation Committee approved the 2023 Multi-Year Long-Term Incentive Program (the “2023 MYLTIP”) awards under the 2021 Plan to certain executive officers of BXP. Earned awards will range from zero to a maximum of 322,053 LTIP Units depending on BXP’s relative and absolute TSR performance, with a target of approximately 161,026 LTIP Units. Under ASC 718, the 2023 MYLTIP awards have an aggregate value of approximately $13.1 million. On February 3, 2023 and February 7, 2023, BXP issued an aggregate of 64,731 shares of restricted common stock and BPLP issued an aggregate of 401,543 LTIP Units under the 2021 Plan to certain employees of BXP. On February 3, 2023, the measurement period for the Company’s 2020 MYLTIP awards ended and, based on BXP.’s relative TSR performance, the final payout was determined to be 50% of target, or an aggregate of approximately $3.8 million (after giving effect to employee separations). As a result, an aggregate of 152,460 2020 MYLTIP Units that had been previously granted were automatically forfeited.
