SEC Chair Supports Rules on Public Company Cybersecurity Disclosures

Today [July 26], the Commission is considering adopting final rules regarding cybersecurity disclosures by public companies. I am pleased to support these rules because they will enhance and standardize disclosures to investors with regard to public companies’ cybersecurity practices as well as material cybersecurity incidents.

Increasingly, cybersecurity risks and incidents are a fact of modern life. When material incidents occur, they can have a range of consequences—including financial, operational, legal, or reputational.

Currently, many public companies provide cybersecurity disclosure to investors. I think companies and investors alike, however, would benefit if this disclosure were made in a more consistent, comparable, and decision-useful way.

Thus, this adoption will enhance public companies’ cybersecurity disclosure in two ways.

First, the rules will require periodic disclosures regarding companies’ risk management, strategy, and governance with respect to cybersecurity risks. This will help investors more effectively assess these risks and make informed investment decisions.

Second, the rules will require disclosure of material cybersecurity incidents. Many public companies already do this, but it’s not done consistently.[1] Thus, today’s final rule will require that if public companies determine that they have experienced a material cybersecurity incident, they must disclose it in a Form 8-K filing. Companies will be required to do so within four business days, consistent with other Form 8-K reporting requirements. To be clear, the disclosure obligation will arise only after the company determines a cybersecurity incident was material, not simply after the incident has occurred.[2]

Congress recognized the benefits to investors of current reporting in enacting the Sarbanes-Oxley Act of 2002.[3] Through the Act, Congress required companies to “disclose to the public on a rapid and current basis such additional information concerning material changes in the financial condition or operations of the issuer… as the Commission determines … is necessary or useful for the protection of investors and in the public interest.”[4]

In 2004, implementing Congress’s mandate, the Commission adopted rules expanding current reporting on a range of matters.[5] Today’s rules will add material cybersecurity incidents to the list of current reporting requirements.

The rules will include limited delays for disclosures of material cybersecurity incidents that the U.S. Attorney General determines could pose a substantial risk to national security or public safety. Further, the adopting release provides that if the Attorney General indicates that further delay is necessary, the Commission will consider additional requests for delay and may grant such relief through possible exemptive orders.

In response to public comment, today’s adopting release streamlines required disclosures for both periodic and incident reporting. For example, the final rules will require issuers to disclose only an incident’s material impacts, nature, scope, and timing, whereas the proposal would have required additional details, not explicitly limited by materiality.

In considering today’s cyber-related disclosure rules, I am guided by the concept of materiality. Our markets depend on a basic bargain: Investors get to decide which risks to take so long as companies raising money from the public make full, fair, and truthful disclosure. Thus, if an issuer has a material cyber incident, then under today’s final rules, the issuer will need to disclose material information about that material incident.

Whether a company loses a factory in a fire—or millions of files in a cybersecurity incident—it may be material to investors.

Over the generations, our disclosure regime has evolved to meet investors’ needs in changing times. Today’s adoption marks only the latest step in that long tradition.

Through helping to ensure that companies disclose material cybersecurity information, today’s rules will benefit investors, companies, and the markets connecting them.

However, staff have observed that this has not resulted in sufficiently consistent, comparable, and decision useful disclosures.

[3] The Commission created Form 8-K in 1936 as the form to be used by companies to file “current” reports when specific extraordinary corporate events occur. The Commission has amended Form 8-K several times in the last four decades to change the 8-K format and timing and the events that would require reporting. For example, refer to the discussion in the 2002 proposing release for what became the 2004 adoption expanding Form 8-K requirements.
