Noncontrolling Interest [Abstract] |
Noncontrolling Interest Disclosure [Text Block] | 9. Noncontrolling Interests Noncontrolling interests relate to the interests in BPLP not owned by BXP and interests in consolidated property partnerships not wholly-owned by the Company. As of September 30, 2025, the noncontrolling interests in BPLP consisted of the following:
OP Units |  | LTIP Units (1) |  | 2023 MYLTIP Units |  | 2024 MYLTIP Units |  | 2025 MYLTIP Units
15,696,776 |  | 2,702,590 |  | 322,053 |  | 330,479 |  | 354,940
__________ (1)Includes 655,534 LTIP Units earned by employees under the Company’s multi-year long-term incentive awards granted between 2012 and 2022 (i.e., 2012 OPP and 2013 - 2022 MYLTIP awards). Noncontrolling Interest—Common Units During the nine months ended September 30, 2025, 143,823 OP Units were presented by the holders for redemption (including an aggregate of 37,944 OP Units issued upon conversion of LTIP Units, 2012 OPP Units and MYLTIP Units) and were redeemed by BXP in exchange for an equal number of shares of Common Stock. At September 30, 2025, BPLP had outstanding the 2023 - 2025 MYLTIP Units. Prior to the end of the respective three-year performance period for each plan, holders of MYLTIP Units are entitled to receive per unit distributions equal to one-tenth (10%) of the regular quarterly distributions payable on an OP Unit, but will not be entitled to receive any special distributions. After the three-year performance period for each plan has ended, (1) the number of MYLTIP Units, both vested and unvested, that MYLTIP award recipients have earned, if any, based on the establishment of a performance pool, will be entitled to receive distributions in an amount per unit equal to distributions, both regular and special, payable on an OP Unit and (2) with respect to the 2023 - 2025 MYLTIP Units, the Company will make a “catch-up” cash payment on the MYLTIP Units that are ultimately earned in an amount equal to the regular and special dividends, if any, declared during the performance period on a number of shares of Common Stock equal to the number of 2023 - 2025 MYLTIP Units that are earned, less the distributions actually paid during the performance period on all of the awarded 2023 - 2025 MYLTIP Units. On January 31, 2025, the three-year measurement period for the Company’s 2022 MYLTIP awards ended and, based on BXP’s absolute and relative TSR performance, the final payout was determined to be 59% of target, or an aggregate of approximately $5.4 million (after giving effect to employee separations). As a result, an aggregate of 177,919 2022 MYLTIP Units that had been previously granted were automatically forfeited. The following table presents BPLP’s distributions on the OP Units and LTIP Units and MYLTIP Units paid or declared in 2025 and during the nine months ended September 30, 2024:
Record Date |  | Payment Date |  | Distributions per OP Unit and LTIP Unit |  | Distributions per MYLTIP Unit
September 30, 2025 |  | October 31, 2025 |  | $0.70 |  |  | $0.070 |
June 30, 2025 |  | July 31, 2025 |  | $0.98 |  |  | $0.098 |
March 31, 2025 |  | April 30, 2025 |  | $0.98 |  |  | $0.098 |
December 31, 2024 |  | January 30, 2025 |  | $0.98 |  |  | $0.098 |
September 30, 2024 |  | October 31, 2024 |  | $0.98 |  |  | $0.098 |
June 28, 2024 |  | July 31, 2024 |  | $0.98 |  |  | $0.098 |
March 28, 2024 |  | April 30, 2024 |  | $0.98 |  |  | $0.098 |
December 29, 2023 |  | January 30, 2024 |  | $0.98 |  |  | $0.098 |
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 must redeem the OP Unit for cash equal to the then value of a share of Common Stock of BXP. BXP may, in its sole discretion, elect to assume and satisfy the redemption obligation by paying either cash or issuing one share of Common Stock. Based on the last reported price of a share of Common Stock on the New York Stock Exchange of $74.34 per share on September 30, 2025, the value of the OP Units (other than OP Units owned by BXP), and LTIP Units (including the 2012 OPP Units and 2013 - 2022 MYLTIP Units), assuming in each case that all conditions had been met for the conversion thereof, had all of such units been redeemed at September 30, 2025 was approximately $1.4 billion. Noncontrolling Interests—Property Partnerships The noncontrolling interests in property partnerships consist of the outside equity interests in ventures that are consolidated with the financial results of the Company because the Company exercises control over the entities that own the properties. The equity interests in these ventures that are not owned by the Company, totaling approximately $2.0 billion and $1.9 billion at September 30, 2025 and December 31, 2024, respectively, are included in Noncontrolling Interests—Property Partnerships on the accompanying Consolidated Balance Sheets. On August 27, 2025, the Company acquired its partner’s 45% ownership interest in the consolidated entity that is developing the 343 Madison Avenue project located in New York City, New York for approximately $43.5 million of cash. The acquisition price is equal to the partner’s aggregate unreturned capital contributions to the joint venture and as a result there was no gain on sale recognized in stockholders’ equity for BXP or partners’ capital for BPLP other than transaction costs. Prior to the acquisition, the Company had a 55% ownership interest in the joint venture (See Note 3).
