Multi-Agent Handoff Drops Mid-Term Endorsement Before Renewal-Pricing Agent Runs

Issue: A Policy-Servicing Agent’s Free-Text Confirmation of a Processed Mid-Term Endorsement (a Risk-Increasing Property Addition, a Removed Discount Condition) Is Not Captured in the Structured Risk-Profile Schema Passed to the Renewal-Pricing Agent, Which Prices the Renewal off the Stale, Pre-Endorsement Risk Profile

Frequency: Occasional

Symptoms

• The renewal prices off the insured value as it stood before a policyholder added a $45,000 detached workshop mid-term, even though the servicing agent’s own confirmation notes record the endorsement, the dollar increase, and the effective date
• Base coverage limit, prior-term premium, and claims history – the inputs the risk-profile schema was designed around – flow into the renewal-pricing agent correctly every time; a mid-term insured-value bump fails specifically because that schema was built to refresh at renewal, not to absorb events that happen between renewals
• The renewal-pricing agent computes a mathematically consistent premium from what it received – it isn’t miscalculating, it’s calculating against a risk profile that stopped being current the day the workshop was added
• The gap is invisible at renewal time because nothing looks wrong: the policy simply renews, at a premium that happens to be lower than the risk it now covers actually warrants
• The mismatch only becomes visible when a claim touches the endorsed risk directly – at which point the underpriced exposure has already been carried for a full renewal term

Root Cause The policy-servicing agent’s endorsement confirmation is written as a narrative update to the policy file – what changed, by how much, effective when – while the renewal-pricing agent consumes a risk-profile schema designed around the standard renewal-cycle refresh, not around mid-cycle events. Because the pricing schema has no field representing “risk profile as of an interim endorsement date,” the renewal-pricing agent has no way to distinguish a policy that was endorsed mid-term from one that wasn’t; both look identical from inside the schema it’s actually reading.

Example

Policyholder adds a detached workshop structure to their property mid-term; policy-servicing agent processes the endorsement, increases the insured value accordingly, and confirms in free-text notes: "Endorsement processed -- detached workshop added, insured value increased $45,000 effective March 15"
Policy-servicing agent hands off renewal-pricing inputs to the renewal-pricing agent using the standard structured schema: base coverage limit, prior-term premium, claims history -- no field exists for "mid-term insured-value change from endorsement"
Renewal-pricing agent prices the renewal using the original, pre-endorsement insured value, since the endorsement was never represented in the structured fields it received
Policy renews underpriced relative to its actual current risk exposure, discovered only when a claim involving the detached workshop arises and a coverage review finds the renewal premium never reflected the added structure

Key Statistics

Contributing Factors

• The renewal-pricing risk-profile schema has no field for a mid-term endorsement that changed the risk profile after the original policy was bound
• No check runs before renewal pricing to compare the policy’s mid-term servicing history against the structured pricing inputs for an unrepresented endorsement
• Endorsements processed outside the standard renewal-cycle refresh are especially likely to fall outside the schema, since the schema was built around the standard renewal-cycle data refresh rather than mid-term events

Mitigation Strategies

1. Mid-Term Risk-Change Field in Pricing Schema: Add a structured “mid-term risk-profile change” field to the policy-servicing-to-renewal-pricing handoff schema that the policy-servicing agent is required to populate whenever it processes an endorsement that changes the insured risk profile
2. Pre-Pricing Endorsement Reconciliation Check: Before pricing the renewal, require a check that compares the policy’s mid-term servicing history against the structured pricing inputs and flags any endorsement not represented in the schema
3. Human Underwriter Review Gate for Flagged Mid-Term Changes: Route any renewal with a populated mid-term risk-change field to human underwriter review before the renewal premium is finalized, rather than allowing the renewal-pricing agent to resolve it automatically
4. Servicing-to-Pricing Traceability Log: Maintain a log linking each renewal-pricing calculation to the mid-term servicing history it was derived from, so a missing endorsement can be caught by audit before the renewal is issued

Metrics

• Rate of renewal-pricing calculations later found, on review, to omit a mid-term endorsement present in the policy’s servicing history
• Rate of pricing handoffs with a populated “mid-term risk-profile change” field versus handoffs where a downstream audit found an endorsement that should have been populated but wasn’t
• Average time between renewal issuance and endorsement-gap detection, when gaps occur

Alerts

• A renewal is priced and issued with a mid-term endorsement present in the servicing history but absent from the structured pricing inputs → P1
• A claim involves a risk that was added via a mid-term endorsement never reflected in the policy’s renewal pricing → P1
• Rate of renewals requiring post-issuance correction for missed mid-term endorsements exceeds the defined threshold for a rolling window → P2
