The Clearance Rules Impact Analysis feature allows you to test how your clearance rules perform using existing alerts. This tool lets you assess the effectiveness of current rules, explore potential changes with draft versions, and evaluate the overall risk associated with your rule set, enhancing your ability to prevent financial crimes effectively.
Running a Clearance Rules Impact Analysis
1. Navigate to the Clearance Rules Interface:
Go to Screening → Clearance rules.
Choose either Person or Transaction Screening tabs at the top of the page.
Scroll to the Impact analyses section at the bottom of the page. Click on an existing analysis to view it or +New analysis to start a new one.
2. Set Up Your Analysis:
When starting a new analysis, provide a name (required) and a description (optional).
Click Save to proceed to the analysis details page where you can manage general information, see previous runs, and start new tests.
3. Define Sample Data for the Test:
Choose the alerts you want to test:
Select alerts generated within a specific timeframe (e.g., from 2024-01-01 to 2024-03-01), or
Choose a set number of the most recent alerts (e.g., the last 1000 alerts), or
Use the same set of alerts from the last run for consistency.
Decide if you want to include FILTERED alerts (those already affected by existing Clearance rules).
Optionally, leave a note for audit purposes, detailing any significant changes or focuses in this test.
4. Start the Test:
Review the list of clearance rules that will be included in the test, shown at the bottom right of the page. This includes all active, inactive, current, historic, and draft versions of rules.
Click Start run to begin the test, which will operate in the background. You can close the window and return later to check the progress.
5. Check Test Status and Results:
The status of the test will be updated in the runs section of the page. Once it shows “Finished”, click View to access the results.
Interpreting the Results
After you have run your analysis, the results provide valuable insights into how your clearance rules are performing. Here’s how to interpret the data presented on the Clearance Rule Analysis page.
General statistics
Initial Alerts: The total number of alerts tested in this run.
Alerts Cleared Previously: Shows the total number and percentage of alerts that were already auto-resolved by the rules before this test. If you chose to exclude FILTERED alerts, this will show as 0.
Alerts Cleared in Current Analysis: Indicates how many and what percentage of alerts are cleared by the current set of rules being tested.
Alerts Remaining: The number and percentage of alerts left for manual review after applying the tested rules.
Impact analysis results
The Impact Analysis table at the bottom of the results page offers a detailed view of the performance of each Clearance rule.
💡 Alerts vs. Hits A Screening Alert encompasses a collection of hits, where each hit represents a potential match identified within the Alert.
Alerts Affected: Refers to alerts where at least one hit is resolved by the rules. This doesn't mean the entire alert is resolved if other hits remain unaffected.
Hits Cleared: Specifies the number of hits within those alerts that were effectively cleared by the rules.

Examples of hits that the rule cleared.
Analysis of hits cleared solely by each rule, meaning those not influenced by any other clearance rule in the test.
Impact on alerts marked with non-final (e.g. Pending) or final-true positive (e.g. Closed as True Positive) statuses, ensuring rules do not overly clear high-risk hits.
