The U.S. Securities and Exchange Commission (the “SEC” or “Commission”) issued interpretive guidance last week relating to disclosure of cybersecurity risks and incidents amid increasing cybersecurity threats from cybercriminals, nation-states, competitors and “hacktivists,” and a host of significant breaches that have come to light in the last year (including one involving the SEC’s EDGAR system). The SEC’s guidance is to some extent a repetition of guidance issued in 2011 by the Commission’s Division of Corporation Finance (“2011 Staff Guidance”) which enhances its authoritativeness, but there are also some new and noteworthy substantive points.
