- Outside pay
- Not shown
- Trades disclosed
- 81
- Took office
- May 2021
Assets disclosed: on the 2025 termination filing. The values on Nelson’s latest financial disclosure to the Office of Government Ethics, added up as ranges, because the form gives ranges and never exact values.
Outside pay: shown for the current administration only. What the latest form reports was paid to the official to the dollar, outside the public salary, which is set by law.
Trades disclosed: Mar 2021 to Dec 2023. Transactions on 278-T reports and annual reports, which include a spouse’s and dependent children’s.
Took office: no leaving date on record.
Outside pay is kept for the current administration only. The Office of Government Ethics drops officials from its public portal after they leave, and by law it destroys most reports six years after they are filed. We saved some earlier reports before they went, but no complete set for any earlier administration survives, and a partial record shown as if it were whole would mislead.
Start date: the cabinet record.

Estimated volume
$3.0M
The forms give each trade as a range of dollars. This adds the low end of every range, so the real volume is at least this and could be much more.
Net worth
Reported as ranges, so no single net worth
- Disclosed assets
- $2.7M to $12M
- Disclosed liabilities
- None disclosed
A net worth for Clarence W. Nelson cannot be computed from this filing: values are given as ranges, some items carry no value, and a home kept for personal use is not reported.
- Disclosed assets:
- as ranges on 31 line items, plus 3 without a dollar value
- Disclosed liabilities:
- none reported on this filing
These are the lower and upper bounds of the ranges on the filing, not a market valuation. Assets and liabilities are shown separately and are never netted into a net worth. How these bands are read
Kept since Aug 28, 2026. Federal law generally requires a filing to be destroyed six years after it was received, unless it is needed in an ongoing investigation.
Disclosures: Office of Government Ethics, read through Oct 24, 2026. Latest filing: 2025 termination filing.
