Within 24 hours of that conclusion, submit a written notification to the Commission, made on a good faith, best efforts basis, that describes the SCI event and the systems affected and, to the extent available, your assessment of the market participants potentially affected, the potential impact on the market, and the steps you have taken, are taking or plan to take.

A notification incident is the subset of computer-security incidents that has materially disrupted or degraded, or is reasonably likely to materially disrupt or degrade, your ability to serve customers, a business line, or an operation whose failure would threaten the financial stability of the United States, so a computer-security incident that falls short of that threshold does not by itself start this clock.
