• Footnote summary:
  • LTIP Units are limited partnership interest units issued under BXP, Inc.’s equity incentive programs and are derivative awards (may convert to Common OP Units).
  • Upon conversion, Common OP Units may be redeemed for cash equal to the fair market value of BXP common stock or, at BXP’s election, exchanged for one share of BXP common stock. LTIP Units have no expiration.
  • Vesting: the 3,332 LTIP Units vest on the earlier of May 29, 2027 or BXP’s 2027 annual meeting of stockholders.

Context
This is a standard equity-compensation grant to a director. Such awards are part of executive/director pay and do not by themselves indicate buying or selling pressure in the market. Because these are derivative LTIP Units (with conversion/redemption features), they differ from immediate common-share purchases; their economic value depends on future conversion/redemption terms and BXP’s stock value at conversion.
