Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us.

- Lee Ehmke participates in a 457(b) Top Hat plan. The contribution for 2024 was $20,348.
- Part I, Line 7
- The Houston Zoo has an Incentive Plan for eligible individuals based on their achievement of organizational goals and individual/department goals aligned with the Zoo's Strategic Plan. The Human Resources Committee of the Board reserves the right to amend, modify, suspend, or terminate the Leadership Incentive Plan, in whole or in part, at any time, for any reason, with or without notice. The CEO retains the discretion to withhold any or all portions of the Plan payout to an eligible employee or employees for performance, disciplinary or other reasons.
Part I's answers as filed. A line not listed was left unanswered; on lines 1a and 3 that means the box was not checked.
