Methodology + sources

Vital Signs Score
Composite of five pillar sub-scores, each 0–100. Weights: Liquidity 20%, Securities 15%, Capitalization 25%, Asset Quality 25%, Reserves 15%. Pillars with no available metrics are dropped from the denominator (renormalised). See functions/src/vitalSignsScore.ts for exact formula and sub-score band anchors.
Pillar status
Strong ≥ 80, Stable ≥ 60, Watch ≥ 40, Risk < 40. Bands are scoring buckets, NOT regulatory thresholds.
Watch Items
Per-pillar rule trips with severity (Risk / Watch / Info) assigned by how far the metric breaches its threshold. Top-3 panel ranks across pillars: severity dominates, magnitude breaks ties.
Adjusted NPL
Noncurrent loans minus government-guaranteed nonaccrual (sourced from FFIEC Schedule RC-N Memorandum item 2). Strips out exposure with implicit US government backing, the same formula used by the Loan Restructuring Watch builder.
True Loss Coverage Ratio
ALLL ÷ (Adjusted NPL + Performing Mods). Surfaces under-reservation that conventional ALLL/NPL hides when banks aggressively modify rather than charge off.
Past-due 30-89 / 90+ PD
Bank-wide totals from FFIEC Schedule RC-N (30-89 days past due and 90+ days past due still accruing) divided by total loans and leases (net of unearned income). Score bands: 30-89 PD Good 0.3% / Bad 3.0%; 90+ PD Good 0.1% / Bad 2.0%.
Source data
FFIEC Call Report Schedules RC, RC-A, RC-B, RC-E, RC-M, RC-N, RC-R, RI, and RI-B Pt I/II via CallReport_Financials + CallReport_FdicData (Visbanking nightly ingest).

Five-pillar framework follows industry-standard bank-health analytical conventions. Composite scoring, Watch Item rules, and per-quarter URL surface are Visbanking's own work.
