What this means
2 of the 12 banks under $100B in assets with a branch in Plymouth County are above a regulatory CRE concentration threshold, and together they hold 2.2% of the county deposits this report covers. Another 1 carries commercial real estate above 300% of capital without meeting the three-year growth test, which is why the broader share is 19%. 3 more sit within one quarter of a threshold.
Coverage is 60%: the rest of the deposits in Plymouth County sit in banks above the $100B threshold, which this report does not evaluate. Concentration is exposure, not loss. A bank above a threshold is one the 2006 interagency guidance expects to hold more capital and document its underwriting, not one that has lost money. We tested whether counties in the top quartile of this score went on to deteriorate faster over the following eight quarters, and found no relationship. The backtest is published in full.
Concentration measures exposure, not loss. This is a map of exposure, not a forecast: our published backtest found no relationship between a county's score and subsequent deterioration.
