Why is Yiu Sun Lee on the disclosure list?

What does “salary paid” include?
What the employer paid in the calendar year, so it can include overtime, retroactive pay, vacation payouts, severance or a partial year. Taxable benefits are listed separately. How the lists work
What do the comparisons mean?
Ranks and shares are among people on the same year’s list only: those with the same title, those at the same employer, or everyone listed. People paid under $100,000 are not on the list, so they are not counted.
How do I report a mistake or ask for a record to be removed?
