Statement mapping

Define the ratio before dividing

Choose a model and name the fields, period and balance basis. A ratio label can hide different numerators, denominators and accounting choices.

Do not let the label choose the inputs

Debt can mean total liabilities, interest-bearing debt, net debt or another bounded measure. Return can be accounting income, cash flow or market value change. NYU Stern’s financial definitions illustrates why the basis and rationale must accompany a ratio. Industry context and accounting policy can change what a comparison means.

Zero is not a rounding problem. A zero denominator produces an undefined state. A negative denominator stays visible and requires interpretation rather than silent coercion.
