About these balances

Latest available filing per company, not a reconstructed current portfolio. Matching sequences show the last reported balance with all source rows expandable; grouping alone does not establish account ownership. Do not add unresolved positions together. Filings may omit unchanged positions, and amendments may correct only part of an older disclosure. Jointly reported shares are not necessarily this owner's personal holdings.

F1: Represents units of limited partnership interest in the Issuer earned (i.e., for which the performance-based hurdles have been met) pursuant to BXP, Inc.'s ("BXP's"), the Issuer's sole general partner's, 2023 Multi-Year Long-Term Incentive Program (the "Program").

F2: Conditioned upon minimum allocations to the capital accounts of the LTIP Units for federal income tax purposes, each LTIP Unit may be converted, at the election of the Issuer or the holder, into a common unit of limited partnership interest in the Issuer ("Common OP Unit"). Each Common OP Unit acquired upon conversion of an LTIP Unit may be presented for redemption, at the election of the holder, for cash equal to the then fair market value of a share of BXP's common stock, except that BXP may, at its election, acquire each Common OP Unit so presented for one share of BXP's common stock. LTIP Units have no expiration date.

F3: The LTIP Units earned pursuant to the Program vested in full upon being earned. Each earned LTIP Unit and Common OP Unit acquired upon conversion of such LTIP Unit is subject to an additional post-vesting holding period pursuant to which such LTIP Unit and Common OP Unit generally may not be transferred, and the redemption right associated with the Common OP Unit may not be exercised, until one year after the vesting date.

F4: Reflects the forfeiture of 5,222 LTIP Units originally issued on February 7, 2023 pursuant to the Program that were previously reported as beneficially owned by the Reporting Person, but remained subject to certain performance-based vesting hurdles based on the Issuer's total shareholder return for the period from February 7, 2023 to February 6, 2026.
