Amounts are per share and adjusted for stock splits, so early payments appear smaller than the cash paid at the time; a year with an extra or missing ex-date shows as a jump in the annual table. Change compares each regular payment with the previous regular one; payments of at least 2.5 times the recent median are treated as specials.
