What is Ex Post?
Definition and Purpose
Ex Post, derived from Latin meaning “after the fact,” refers to activities or observations made retrospectively, after an event or phenomenon has occurred. It is used to analyze past data, assess outcomes, or conduct evaluations once actual results are available. In accounting and finance, Ex Post analysis helps to review financial performance, evaluate investment decisions, or assess the effectiveness of policies based on historical data.
Key Points to Understand
- Retrospective Analysis: Ex Post analysis involves examining events or data after they have occurred, contrasting with Ex Ante analysis which is done before events.
- Evaluation Tool: It is a critical tool in assessing the accuracy of forecasts, financial performance, and decision-making processes based on actual outcomes.
- Application: Commonly used in economic studies, financial reporting, risk management, and academic research to draw conclusions from historical data.
