Why it Matters?
The extended reporting period is the mechanism protecting professionals who retire, change carriers, or close a practice, and the purchase decision is time-limited, typically requiring election within thirty to sixty days of expiration. Missing that window leaves prior work uninsured with no remedy. The distinction that confuses insureds is that it extends reporting, not coverage, so conduct after expiration is never covered.
