# Finance Variance Analysis
## Purpose
Explain a variance — actual vs. plan, actual vs. prior period, or actual vs. forecast — with decomposition (volume / price / mix / FX / timing), driver attribution, run-rate impact, and management-voice commentary. The deliverable supports management review, board reporting, MD&A drafting, and forecast-revision decisions.

- Produces the variance bridge, decomposition, and commentary; does not revise the forecast (handoff to finance-forecast-update once available) and does not produce SEC disclosure language (handoff to finance-disclosure-language for MD&A drafting).
- Operates on closed actuals — does not opine on whether close-cycle accruals are correctly stated (handoff to finance-reconciliation if a balance is suspect).
- Does not score the forecast process itself; this is a backward-looking analysis.
## Inputs
- Actual results for the period (revenue, gross profit, opex, EBITDA, or the line items in scope)
- Plan / budget figures for the same period (with version identifier — AOP, latest forecast, prior year)
- Prior-period actuals for the same line items (period-over-period basis)
- Source identifiers and timestamps for each data set (system, report, run timestamp)
- Volume, price, and mix detail at the SKU / customer / segment grain where available
- FX rates (period actuals, plan rates) for multi-currency entities
- Materiality threshold for driver call-outs (per firm policy — typically the lower of $X o
