ex ante

Before the fact

Ex ante means beforehand or based on forecasts rather than actual results.

The Latin phrase appears in economics, finance, and law to describe analysis or expectations formed before an event occurs: Ex ante, the investment looked promising.

It contrasts with ex post, which refers to assessment after the fact.
