Sample case

A synthetic trade checked against synthetic firm policy. The people and the company are invented.

Case 9: Amendment replaces a flagged trade

Vice President files an amendment (Form 4/A) for a $3,000 sale

In this sample, an earlier version of the filing reported a much larger trade before it was corrected. A system that reads every version would still flag it. Counting only the latest record is the right behavior.

Reasons for concern

Amendments can change what was first reported, so the earlier version has to be accounted for.

What could explain it

At $3,000, the trade is under the $3,000,000 single-trade limit for this role.
Replaced filings are kept on record but left out of the totals, so an earlier version does not drive the result.

Answer key

Clear

Set when the scenario was designed. A rules-based reference investigation reaches it from the evidence.

FindingThe investigation's outcome. Clear means nothing to follow up, flag means an analyst should look, escalate means it needs urgent review.

Exculpatory factorsA fact from the filing that explains a trade innocently, such as tax withholding or an option exercise. Each one applies to a single transaction line, never to the whole filing.

Claims checkOne factual sentence pulled out of the draft so it can be checked on its own.

Process auditA check, done in code, of how the investigation got to its finding: whether it gathered all the evidence, cited only real tool calls and claimed only supported exemptions.
