description: "FDIC deposit-insurance assessment rate calculator (12 CFR 327): looks up the base assessment rate for a supplied composite CAMELS + financial-ratio score against a caller-supplied rate schedule, then applies the unsecured-debt and brokered-deposit adjustments and floors/caps the result to a caller-supplied statutory range. The rate schedule is caller-supplied policy input, not hardcoded, so a future FDIC rate-schedule update (including a pending assessments rulemaking) is a policy_parameters change, not a kernel change. Does not compute the composite CAMELS score itself."
