  1. Michael A. Lawless's transaction reports restate only vehicles that traded; the 2025 ownership statement (3.61M) plus the 226.7K net shares acquired since is used instead.
  2. Marvin Slosman's own ownership statement (13D, Apr 24, 2026) plus the 21.0K net shares acquired since reports fewer shares than the transaction reports; the statement is used.
  3. Reported at 3.50% on Oct 29, 2025, under the 5% line, so no further filing is required.
