Context

• The M-code (exercise/conversion) entries reflect conversion/settlement of derivative awards (here, RSUs) into common shares. The matching disposed entry commonly represents shares withheld or surrendered to satisfy tax-withholding obligations upon vesting.
• The A-code entry is a new RSU grant that will vest per the schedule in footnote F4; grants and vesting events reported at $0 are routine compensation events and do not represent open-market purchases or sales.
• These filings are informational for investors; they record compensation-related share movements by an insider and do not by themselves indicate a buy/sell decision in the open market.
