Context

LTIP Units are units of limited partnership issued under the issuer’s equity incentive program. They can convert into common OP units and may be redeemable for cash equal to the fair market value of a share of BXP’s common stock or, at BXP’s election, exchanged for one share of BXP common stock (see footnote F1). LTIP Units have no expiration date.
This is a compensation award (not an insider buy or sell); such grants can reflect routine executive compensation and do not by themselves indicate insider buying or selling sentiment.
