A year-over-year increase or decrease in disclosed pay can include overtime, a retroactive payment, a vacation payout or severance, not only a change in base pay, rate, or role — the Sunshine List discloses total salary paid that year, not a pay rate. This list is ranked by the dollar increase, not by the percentage shown.
