Carrier appointment durability — the tenure signal.

Carrier appointments are not all equal, and tenure is the most direct way to tell them apart. A 20-year appointment has earned the carrier's trust through a full commercial cycle; a 2-year appointment hasn't. The implications are tangible — long-tenured agencies receive better underwriting treatment, priority quote turnaround, and deeper conversations about appetite changes, and tenure correlates with earned authority: binding scope, contingency tier eligibility, and specialty product access all expand as carriers extend more latitude to agencies they've watched perform. Buying a long-tenured book is buying that accumulated latitude alongside the book itself.

§ 01 · The distributionAnchor, middle, recent.

Tenure in a typical book isn't uniform — three clusters emerge. Anchor appointments are the top three to five carriers, usually the longest-tenured at 10 to 25 years; they define the agency's operating model and underwriting culture. Middle-tier appointments run 5 to 15 years, added during the growth phase — solid but not yet at anchor status. Recent appointments are the last one to five years, added for market changes, client needs, or new producers — operational but unproven. The anchor-middle-recent shape is normal; what buyers scrutinize is its silhouette. A book whose top carriers are all under five years is a very different asset than one with deep anchors, and a book with no recent appointments at all may signal that the agency has stopped investing in carrier expansion — a forward-looking concern even when the current profile looks healthy.

§ 02 · Quantifying the signalThree metrics.

The three together give a defensible tenure profile, and they map onto a valuation band. Deep-tenure books — 12+ year weighted average, anchors all 15+ — trade at the top of the comparable range; mixed-tenure books — 8 to 12 year average, anchors mostly 10+ — at the middle, with standard diligence; shallow-tenure books — under 8 years, or some anchors under five — trade at the bottom or require additional seller support, typically earnouts, extended transition periods, or specific producer-retention commitments. The bands compound with other signals: a shallow-tenure book with rising loss ratios is a different deal than a shallow-tenure book with clean ratios and a clear strategic-expansion narrative.

§ 03 · When short tenure is fineThree explanations.

Short tenure is a flag, not automatically a problem, and three contexts resolve it. Recent expansion — entering a new line of business, a new region, or onboarding a specialty producer — accumulates short-tenured appointments by design, and the strategic logic matters more than the tenure math. Carrier consolidation periodically resets the clock: an appointment migrated from a recently acquired carrier to the acquiring group's paper shows as short-tenured even though the underlying relationship is much older. And deliberate refresh — sophisticated agencies rotating relationships to refresh appetite, consolidate volume, or exit underperformers — can create apparent tenure weakness that actually reflects active portfolio management. The diligence test is simple: does the short tenure have an explainable business reason? When it does, the flag is resolved; when it doesn't, the flag stands.

§ 04 · Tenure predicts consent riskWork the short ones first.

This is the counter-intuitive move that the tenure profile unlocks. The instinct is to sequence consent outreach by premium size, but the risk isn't concentrated there — it's concentrated in the relationships the acquiring entity hasn't yet earned. A long-tenured anchor has institutional weight that the change of control doesn't easily disturb; a recent appointment may not have enough performance history for the carrier to extend the same latitude to a new owner. Reading the tenure distribution before the consent process tells the buyer exactly where to spend the scarce senior-relationship capital, and it's the difference between a clean transfer and a re-qualification that quietly narrows the book on day one.
