Assess whether a claims ring exists or is coincidental overlap (e89f49)

Situation

After a mule account receiving 14 unrelated payrolls in a week, bust-out credit-line utilization curve is what account-opening quality reviewer can touch in an ACH originating credit union. Fraud Detection will live with A claims ring exists versus Is coincidental overlap on this Mortgage Fraud file.

Decision

Account-opening quality reviewer in an ACH originating credit union must choose A claims ring exists / Is coincidental overlap using bust-out credit-line utilization curve after a mule account receiving 14 unrelated payrolls in a week.

Hypotheses to test

• The population in bust-out credit-line utilization curve is the one a mule account receiving 14 unrelated payrolls in a week named, so A claims ring exists follows for this Mortgage Fraud file.
• The population in bust-out credit-line utilization curve is adjacent only to a mule account receiving 14 unrelated payrolls in a week; Is coincidental overlap is the honest Fraud Detection call.
• An ACH originating credit union already contained a mule account receiving 14 unrelated payrolls in a week before bust-out credit-line utilization curve arrived; no new Mortgage Fraud path.
• Provenance on bust-out credit-line utilization curve after a mule account receiving 14 unrelated payrolls in a week is broken; do not pick A claims ring exists or Is coincidental overlap yet.

Analysis required

• Trace funds, counterparties, and reversals in bust-out credit-line utilization curve through the window opened by a mule account receiving 14 unrelated payrolls in a week.
• Quantify loss if the hold is released before bust-out credit-line utilization curve is complete.
• Test a one-off dispute against the first edge of a scheme around a claims ring exists.
• For this Fraud Detection Mortgage Fraud file, read bust-out credit-line utilization curve against a mule account receiving 14 unrelated payrolls in a week and write the one fact that would move a claims ring exists for account-opening quality reviewer.

Recommendation

Choose A claims ring exists / Is coincidental overlap on this Fraud Detection / Mortgage Fraud packet (bust-out credit-line utilization curve after a mule account receiving 14 unrelated payrolls in a week). The follow-on Mortgage Fraud action is what account-opening quality reviewer does next: implement the option, assign an owner, and log the missing fact.
