Banking Review / Deal Surface / 2026-05-29
The DealCard decision instrument begins by articulating PRC Proximate Residents Catchment accretion, upon minting a specific merger scenario.
PRC Bridge
EASTERN + Them: HARBORONE
507,387 Me-only PRC + 0 Me PRC in co-trade regions + 0 Them accretion in co-trade regions + 0 Them-only accretion = 507,387 merged PRC
SMARTMARKETS VALUE PROP
Mint-ready: for any next-deal Them-target;
PRC accretion: normalized drill down into trade regions, compass subregions, fit + fill-in readout;
Regulator: density read out;
Due Diligence prep: branch fit motions;
First steps into: site network lifecycle/pruner (eg mint MatchMaker for Me vs All-Them);
If you want, designed to wire into your team decision workflow;
Based on current FFIEC branches; census residents.
SLIDE 2 / CO-TRADE MINI REPORT
Co-trade regions, ordered by Them accretion PRC:
(none @ this exhibit slice — geographic complementarity)
Them-only trade regions:
(none @ this exhibit slice)
SLIDE 3 / PRC LEARNINGS
The usual question: where do these networks overlap?
The Smartmarkets question: what resident catchment does the combined network accrete?
PRC is precomputed before the dealcard starts.
A merger changes ownership of sites whose proximate catchment was already settled.
The bridge is intentionally boring: reassemble ownership of already-attributed residents.

OPB METHODOLOGY
ORR is the change-control rail for this Explainer — one FFIEC stack per cvr_cycle_id, one narrative pin per pre-close deal.
Deal teams should recognize these TRNSFM markings; OPB foots them at the Explainer cut plane for client-side audit.
Me = slice @ pin. Them = merged standalone @ pin. Post-close absorption is a lineage assumption only.
PRC bridge reads Smartmarkets LIBRARY at pin-replayed org_keys — same accretion instrument as forward minted DealCard, just with a past-tense exemplary cut.
See Prompt Chip for the production mint on your next deal. This Review Explainer trains the bridge — not production mint (you will not be able to mint this deal card; Them is already rolled under).
