Context These are derivative phantom stock units tied to Cabot’s supplemental 401(k) plan and are slated to be settled when Mr. Keohane retires or leaves the company — they are not immediately tradable common shares. Awards like this are compensation-related and should be viewed differently from open‑market purchases or sales; they do not by themselves indicate a buy/sell signal.
