Successor in interest — preserving the carrier track record.

The carrier premium map can show a beautiful combined tier position, but it assumes the acquired appointment carries its history into the combined entity — and the carrier's default assumption is the opposite. Left alone, a carrier rebases an acquired appointment to zero, which can erase the very tier position and loss-ratio history the synergy depended on. Successor-in-interest provisions are how a buyer preserves what the map promised, and the time to negotiate them is before the notices go out.

§ 01 · The default rebaseWhat the carrier does by default.

The carrier's default posture on a change of control is to rebase: zero out the volume track record, discard the 3-year loss-ratio lookback, restart tier qualification, and withhold or reserve the transition-year contingency. The financial impact is concrete — a carrier paying 12% contingency under a Tier-3 position drops the acquired appointment back to Tier 1, so a $400K seller-era contingency line can underperform by $100K–$200K in Year 1 absent a successor-in-interest provision. That's the gap between the combined tier position the premium map modeled and what the carrier will actually pay if the buyer does nothing — which is why the map's tier-jump synergy is conditional on preserving the history, not automatic. The map sizes the prize; successor-in-interest is what secures it.

§ 02 · Three continuity asksWhat preserves the record.

The three continuity asks are what a buyer negotiates to convert the default rebase into a preserved track record. Volume continuity means the premium written under the seller counts toward the acquirer's tier position, so the combined book qualifies at the higher tier rather than restarting. Loss-ratio continuity means the seller's loss-ratio history transfers cleanly, so a clean history isn't discarded. And contingency continuity means the pre-close earnings pay as scheduled, and the post-close period runs against the combined track record. For the top 3–5 carriers by premium and contingency — the ones that move the map the most — a buyer adds an explicit tier-lock for the transition year, guaranteeing the tier position while the combined book establishes its own record. These asks are what make the tier-jump synergy the premium map showed actually materialize. The operational transfer that runs alongside is in carrier appointment transfer.

§ 03 · Trade-offers and "start fresh"Winning the asks, or inverting them.

A buyer wins successor-in-interest by offering the carrier something in return. Standard trade-offers: a direct underwriting review of the acquirer (financial statements, principal bios, E&O evidence), a 12–24 month written-premium commitment, a loss-ratio commitment (often tied to the 60% gate), and relationship continuity (key staff retained through the first renewal cycle). The carrier grants continuity because the acquirer is demonstrating it's a good risk and a committed partner. There's also an inverse provision — "start fresh" — used when the seller's loss-ratio history would drag the inherited contingency toward zero. Here the acquirer asks the carrier to discard the history and treat the appointment as new, restarting the 3-year clock. It's winnable in three scenarios: a single concentrated account drove a loss-ratio trap, the seller's contingency history is weak so the combined-book math is stronger from scratch, or the carrier's relationship manager is signaling heavier continuation conditions than a fresh start would carry. The choice between asking for continuity and asking to start fresh depends on whether the seller's history helps or hurts — which the loss-run lookback reveals, as covered in the three-year lookback.

§ 04 · The pre-LOI leverage windowAnd the six-step checklist.

The decisive insight is timing: a buyer's leverage to win successor-in-interest is highest before the change-of-control notices are sent, and it collapses sharply post-LOI once the carrier knows the deal is happening regardless. The change-of-control clause severity spectrum frames the negotiation — a termination right (unilateral, full stop), a consent right (the acquirer must be approved), or a passive notification requirement — and the buyer's leverage depends partly on which applies. A six-step pre-LOI carrier checklist captures the window: pull every agreement for carriers above 5% of premium or contingency; identify the top 3–5 must-win continuity targets; identify the "start fresh" candidates; make preliminary relationship-manager calls without disclosing the specific deal; price the clean-reset downside into the valuation model; and structure the LOI with a 90-day diligence window to leave negotiating room. Run that checklist pre-LOI, and the buyer either preserves the track record or knows to price its loss — which is the difference between a premium map that delivers and one that overstated the synergy. The code-architecture decision that depends on the successor-in-interest outcome is in agency-code architecture.
