Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization | 1. Organization BXP is a fully integrated, self-administered and self-managed REIT. BXP is the sole general partner of BPLP, its operating partnership, and at March 31, 2025, owned an approximate 89.6% (89.7% at December 31, 2024) general and limited partnership interest in BPLP. Unless stated otherwise or the context requires, the “Company” refers to BXP and its subsidiaries, including BPLP and its consolidated subsidiaries. Partnership interests in BPLP include: •common units of partnership interest (also referred to as “OP Units”) and •long term incentive units of partnership interest (also referred to as “LTIP Units”) Unless specifically noted otherwise, all references to OP Units exclude units held by BXP. A holder of an OP Unit may present the OP Unit to BPLP for redemption at any time (subject to covenants agreed upon at the time of issuance of OP Units to particular holders that may restrict such redemption right for a period of time, generally one year from issuance). Upon presentation of an OP Unit for redemption, BPLP is obligated to redeem the OP Unit for cash equal to the value of a share of common stock of BXP (“Common Stock”). In lieu of such cash redemption, BXP may elect to acquire the OP Unit for one share of Common Stock. Because the number of shares of Common Stock outstanding at all times equals the number of OP Units that BXP owns, one share of Common Stock is generally the economic equivalent of one OP Unit, and the quarterly distribution that may be paid to the holder of an OP Unit equals the quarterly dividend that may be paid to the holder of a share of Common Stock. The Company uses LTIP Units as a form of time-based, restricted equity compensation and as a form of performance-based equity compensation for employees, and it has previously granted LTIP Units in the form of (1) 2012 outperformance plan awards (“2012 OPP Units”) and (2) 2013 - 2025 multi-year, long-term incentive program awards (also referred to as “MYLTIP Units”), each of which, upon the satisfaction of certain performance-based and time-based vesting conditions, is convertible into one OP Unit. The three-year measurement periods for the 2012 OPP Units and the 2013 - 2022 MYLTIP Units have ended and BXP’s total stockholder return (“TSR”) was sufficient for employees to earn and therefore become eligible to vest in a portion of the awards. Unless and until they are earned, the rights, preferences and privileges of the 2023 - 2025 MYLTIP Units differ from other LTIP Units granted to employees (including the 2012 OPP Units and the 2013 - 2022 MYLTIP Units, which have been earned). Therefore, unless specifically noted otherwise, all references to LTIP Units exclude the 2023 - 2025 MYLTIP Units. LTIP Units (including the earned 2012 OPP Units and the earned 2013 - 2022 MYLTIP Units), whether vested or not, receive the same quarterly per unit distributions as OP Units, which equal per share dividends on Common Stock (See Notes 9 and 13). Properties At March 31, 2025, the Company owned or had joint venture interests in a portfolio of 185 commercial real estate properties (the “Properties”) aggregating approximately 53.4 million net rentable square feet of primarily office properties, including nine properties under construction/redevelopment totaling approximately 3.0 million net rentable square feet. At March 31, 2025, the Properties consisted of: •162 office properties (including six properties under construction/redevelopment); •14 retail properties (including one property under construction); •eight residential properties (including two properties under construction); and •one hotel.
