Introduction
Most CECL implementations technically comply with the standard but fail a more important test: they cannot explain why the reserve moves. This session reframes CECL as a structured decision system rather than a black-box output. We will walk through four pillars that determine whether a CECL framework is strong, auditable, and strategically useful:
- The right inputs (what data matters)
- The right granularity (when aggregation destroys information)
- The right structure (why discounted cash flow is superior)
- The right conditional logic (assumptions that respond to credit attributes & macroeconomic influence)
