Cybersecurity Risk Management, Strategy, Governance, and Incident Disclosure
AGENCY: Securities and Exchange Commission.
ACTION: Final rule.
SUMMARY: The Securities and Exchange Commission (“Commission”) is adopting new rules
to enhance and standardize disclosures regarding cybersecurity risk management, strategy,
governance, and incidents by public companies that are subject to the reporting requirements of
the Securities Exchange Act of 1934. Specifically, we are adopting amendments to require
current disclosure about material cybersecurity incidents. We are also adopting rules requiring
periodic disclosures about a registrant’s processes to assess, identify, and manage material
cybersecurity risks, management’s role in assessing and managing material cybersecurity risks,
and the board of directors’ oversight of cybersecurity risks. Lastly, the final rules require the
cybersecurity disclosures to be presented in Inline eXtensible Business Reporting Language
(“Inline XBRL”).

Introduction and Background
On March 9, 2022, the Commission proposed new rules, and rule and form amendments,

to enhance and standardize disclosures regarding cybersecurity risk management, strategy,
governance, and cybersecurity incidents by public companies that are subject to the reporting
requirements of the Exchange Act. 3 The proposal followed on interpretive guidance on the
application of existing disclosure requirements to cybersecurity risk and incidents that the
Commission and staff had issued in prior years.
In particular, in 2011, the Division of Corporation Finance issued interpretive guidance
providing the Division’s views concerning operating companies’ disclosure obligations relating
to cybersecurity (“2011 Staff Guidance”). 4 In that guidance, the staff observed that “[a]lthough
no existing disclosure requirement explicitly refers to cybersecurity risks and cyber incidents, a
number of disclosure requirements may impose an obligation on registrants to disclose such risks
and incidents,” and further that “material information regarding cybersecurity risks and cyber
incidents is required to be disclosed when necessary in order to make other required disclosures,
in light of the circumstances under which they are made, not misleading.” 5 The guidance pointed
specifically to disclosure obligations under 17 CFR 229.503 (Regulation S-K “Item 503(c)”)
(Risk factors) (since moved to 17 CFR 229.105 (Regulation S-K “Item 105”)), 17 CFR 229.303
(Regulation S-K “Item 303”) (Management’s discussion and analysis of financial condition and
results of operations), 17 CFR 229.101 (Regulation S-K “Item 101”) (Description of business),
17 CFR 229.103 (Regulation S-K “Item 103”) (Legal proceedings), and 17 CFR 229.307

(Disclosure controls and procedures), as well as to Accounting Standards Codifications 350-40
(Internal-Use Software), 605-50 (Customer Payments and Incentives), 450-20 (Loss
Contingencies), 275-10 (Risks and Uncertainties), and 855-10 (Subsequent Events). 6
In 2018, “[i]n light of the increasing significance of cybersecurity incidents,” the
Commission issued interpretive guidance to reinforce and expand upon the 2011 Staff Guidance
and also address the importance of cybersecurity policies and procedures, as well as the
application of insider trading prohibitions in the context of cybersecurity (“2018 Interpretive
Release”). 7 In addition to discussing the provisions previously covered in the 2011 Staff
Guidance, the new guidance addressed 17 CFR 229.407 (Regulation S-K “Item 407”) (Corporate
Governance), 17 CFR Part 210 (“Regulation S-X”), and 17 CFR Part 243 (“Regulation FD”). 8
The 2018 Interpretive Release noted that companies can provide current reports on Form 8-K
and Form 6-K to maintain the accuracy and completeness of effective shelf registration
statements, and it also advised companies to consider whether it may be appropriate to
implement restrictions on insider trading during the period following an incident and prior to
disclosure. 9
As noted in the Proposing Release, current disclosure practices are varied. For example,
while some registrants do report material cybersecurity incidents, most typically on Form 10-K,
review of Form 8-K, Form 10-K, and Form 20-F filings by staff in the Division of Corporation
Finance has shown that companies provide different levels of specificity regarding the cause,
scope, impact, and materiality of cybersecurity incidents. Likewise, staff has also observed that,

while the majority of registrants that are disclosing cybersecurity risks appear to be providing
such disclosures in the risk factor section of their annual reports on Form 10-K, the disclosures
are sometimes included with other unrelated disclosures, which makes it more difficult for
investors to locate, interpret, and analyze the information provided. 10
In the Proposing Release, the Commission explained that a number of trends underpinned
investors’ and other capital markets participants’ need for more timely and reliable information
related to registrants’ cybersecurity than was produced following the 2011 Staff Guidance and
the 2018 Interpretive Release. First, an ever-increasing share of economic activity is dependent
on electronic systems, such that disruptions to those systems can have significant effects on
registrants and, in the case of large-scale attacks, systemic effects on the economy as a whole. 11
Second, there has been a substantial rise in the prevalence of cybersecurity incidents, propelled
by several factors: the increase in remote work spurred by the COVID-19 pandemic; the
increasing reliance on third-party service providers for information technology services; and the
rapid monetization of cyberattacks facilitated by ransomware, black markets for stolen data, and
crypto-asset technology. 12 Third, the costs and adverse consequences of cybersecurity incidents
to companies are increasing; such costs include business interruption, lost revenue, ransom
payments, remediation costs, liabilities to affected parties, cybersecurity protection costs, lost
assets, litigation risks, and reputational damage. 13

See infra Section IV.A (noting that current cybersecurity disclosures appear in varying sections of companies’
periodic and current reports and are sometimes included with other unrelated disclosures).

system”).

Since publication of the Proposing Release, these trends have continued apace, with
significant cybersecurity incidents occurring across companies and industries. For example,
threat actors repeatedly and successfully executed attacks on high-profile companies across
multiple critical industries over the course of 2022 and the first quarter of 2023, causing the
Department of Homeland Security’s Cyber Safety Review Board to initiate multiple reviews. 14
Likewise, state actors have perpetrated multiple high-profile attacks, and recent geopolitical
instability has elevated such threats. 15 A recent study by two cybersecurity firms found that 98
percent of organizations use at least one third-party vendor that has experienced a breach in the
last two years. 16 In addition, recent developments in artificial intelligence may exacerbate
cybersecurity threats, as researchers have shown that artificial intelligence systems can be
leveraged to create code used in cyberattacks, including by actors not versed in programming. 17
Overall, evidence suggests companies may be underreporting cybersecurity incidents. 18

Legislatively, we note two significant developments occurred following publication of
the Proposing Release. First, the President signed into law the Cyber Incident Reporting for
Critical Infrastructure Act of 2022 (“CIRCIA”) 19 on March 15, 2022, as part of the Consolidated
Appropriations Act of 2022. 20 The centerpiece of CIRCIA is the reporting obligation placed on
companies in defined critical infrastructure sectors. 21 Once rules are adopted by the
Cybersecurity & Infrastructure Security Agency (“CISA”), these companies will be required to
report covered cyber incidents to CISA within 72 hours of discovery, and report ransom
payments within 24 hours. 22 Importantly, reports made to CISA pursuant to CIRCIA will remain
confidential; while the information contained therein may be shared across Federal agencies for
cybersecurity, investigatory, and law enforcement purposes, the information may not be
disclosed publicly, except in anonymized form. 23 We note that CIRCIA also mandated the
creation of a “Cyber Incident Reporting Council . . . to coordinate, deconflict, and harmonize
Federal incident reporting requirements” (the “CIRC”), of which the Commission is a member. 24
Second, on December 21, 2022, the President signed into law the Quantum Computing
Cybersecurity Preparedness Act, which directs the Federal Government to adopt technology that
is protected from decryption by quantum computing, a developing technology that may increase

Healthcare and Public Health; Information Technology; Nuclear Reactors, Materials, and Waste; Transportation
Systems; Water and Wastewater Systems. Because these sectors encompass some private companies and do not
encompass all public companies, CIRCIA’s reach is both broader and narrower than the set of companies
subject to the rules we are adopting.

computer processing capacity considerably and thereby render existing computer encryption
vulnerable to decryption. 25
We received over 150 comment letters in response to the Proposing Release. 26 The
majority of comments focused on the proposed incident disclosure requirement, although we also
received substantial comment on the proposed risk management, strategy, governance, and board
expertise requirements. In addition, the Commission's Investor Advisory Committee adopted
recommendations (“IAC Recommendation”) with respect to the proposal, stating that it: supports
the proposed incident disclosure requirement; supports the proposed risk management, strategy,
and governance disclosure requirements; recommends the Commission reconsider the proposed
board of directors’ cybersecurity expertise disclosure requirement; suggests requiring companies
to disclose the key factors they used to determine the materiality of a reported cybersecurity

Quantum Computing Cybersecurity Preparedness Act, H.R. 7535, 117th Cong. (2022). More recently, the
White House released a National Cybersecurity Strategy to combat the ongoing risks associated with
cyberattacks. The National Cybersecurity Strategy seeks to rebalance the responsibility for defending against
cyber threats toward companies instead of the general public, and looks to realign incentives to favor long-term
investments in cybersecurity. See Press Release, White House, FACT SHEET: Biden-⁠Harris Administration
Announces National Cybersecurity Strategy (Mar. 2, 2023), available at https://www.whitehouse.gov/briefingroom/statements-releases/2023/03/02/fact-sheet-biden-harris-administration-announces-nationalcybersecurity-strategy/.

The public comments we received are available at https://www.sec.gov/comments/s7-09-22/s70922.htm. On
Mar. 9, 2022, the Commission published the Proposing Release on its website. The comment period for the
Proposing Release was open for 60 days from issuance and publication on SEC.gov and ended on May 9, 2022.
One commenter asserted that the comment period was not sufficient and asked the Commission to extend it by
30 days. See letter from American Chemistry Council (“ACC”). In Oct. 2022, the Commission reopened the
comment period for the Proposing Release and other rulemakings because certain comments on the Proposing
Release and other rulemakings were potentially affected by a technological error in the Commission’s internet
comment form. See Resubmission of Comments and Reopening of Comment Periods for Several Rulemaking
Releases Due to a Technological Error in Receiving Certain Comments, Release No. 33-11117 (Oct. 7, 2022)
[87 FR 63016 (Oct. 18, 2022)] (“Reopening Release”). The Reopening Release was published on the
Commission’s website on Oct. 7, 2022 and in the Federal Register on Oct. 18, 2022, and the comment period
ended on Nov. 1, 2022. A few commenters asserted that the comment period for the reopened rulemakings was
not sufficient and asked the Commission to extend the comment period for those rulemakings. See, e.g., letters
from Attorneys General of the states of Montana et al. (Oct. 24, 2022) and U.S. Chamber of Commerce (Nov. 1,
2022). We have considered all comments received since Mar. 9, 2022 and do not believe an additional
extension of the comment period is necessary.

incident; and suggests extending the proposed 17 CFR 229.106 (Regulation S-K “Item 106”)
disclosure requirements to registration statements. 27
We are making a number of important changes from the Proposing Release in response to
comments received. With respect to incident disclosure, we are narrowing the scope of
disclosure, adding a limited delay for disclosures that would pose a substantial risk to national
security or public safety, requiring certain updated incident disclosure on an amended Form 8-K
instead of Forms 10-Q and 10-K for domestic registrants, and on Form 6-K instead of Form 20-F
for foreign private issuers (“FPIs”), 28 and omitting the proposed aggregation of immaterial
incidents for materiality analyses. We are streamlining the proposed disclosure elements related
to risk management, strategy, and governance, and we are not adopting the proposed requirement
to disclose board cybersecurity expertise. The following table summarizes the requirements we
are adopting, including changes from the Proposing Release, as described more fully in Section
II below: 29

Item

Summary Description of the Disclosure Requirement 30

Regulation S-K Item 106(b) – Registrants must describe their processes, if any, for the
Risk management and
assessment, identification, and management of material risks
strategy
from cybersecurity threats, and describe whether any risks
from cybersecurity threats have materially affected or are
reasonably likely to materially affect their business strategy,
results of operations, or financial condition.
Regulation S-K Item 106(c) –
Governance

Registrants must:
- Describe the board’s oversight of risks from cybersecurity
threats.
- Describe management’s role in assessing and managing
material risks from cybersecurity threats.

Form 8-K Item 1.05 –
Material Cybersecurity
Incidents

Registrants must disclose any cybersecurity incident they
experience that is determined to be material, and describe the
material aspects of its:
- Nature, scope, and timing; and
- Impact or reasonably likely impact.
An Item 1.05 Form 8-K must be filed within four business
days of determining an incident was material. A registrant
may delay filing as described below, if the United States
Attorney General (“Attorney General”) determines immediate
disclosure would pose a substantial risk to national security or
public safety.

Form 20-F

Form 6-K

30

Registrants must amend a prior Item 1.05 Form 8-K to
disclose any information called for in Item 1.05(a) that was
not determined or was unavailable at the time of the initial
Form 8-K filing.
FPIs must:
- Describe the board’s oversight of risks from cybersecurity
threats.
- Describe management’s role in assessing and managing
material risks from cybersecurity threats.
FPIs must furnish on Form 6-K information on material
cybersecurity incidents that they disclose or otherwise

For purposes of this release, the terms “public companies,” “companies,” and “registrants” include issuers that
are business development companies as defined in section 2(a)(48) of the Investment Company Act of 1940,
which are a type of closed-end investment company that is not registered under the Investment Company Act,
but do not include investment companies registered under that Act.

12

publicize in a foreign jurisdiction, to any stock exchange, or to
security holders.
Overall, we remain persuaded that, as detailed in the Proposing Release: under-disclosure
regarding cybersecurity persists despite the Commission’s prior guidance; investors need more
timely and consistent cybersecurity disclosure to make informed investment decisions; and
recent legislative and regulatory developments elsewhere in the Federal Government, including
those developments subsequent to the issuance of the Proposing Release such as CIRCIA 31 and
the Quantum Computing Cybersecurity Preparedness Act, 32 while serving related purposes, will
not effectuate the level of public cybersecurity disclosure needed by investors in public
companies.
II.

Discussion of Final Amendments
A. Disclosure of Cybersecurity Incidents on Current Reports
1. Proposed Amendments
The Commission proposed to amend Form 8-K by adding new Item 1.05 that would

require a registrant to disclose the following information regarding a material cybersecurity
incident, to the extent known at the time of filing:
•

When the incident was discovered and whether it is ongoing;

•

A brief description of the nature and scope of the incident;

•

Whether any data were stolen, altered, accessed, or used for any other unauthorized
purpose;

•

The effect of the incident on the registrant’s operations; and

31

Supra note 19.

32

Supra note 25.

13

•

Whether the registrant has remediated or is currently remediating the incident. 33

The Commission clarified in the Proposing Release that this requirement would not extend to
specific, technical information about the registrant’s planned response to the incident or its
cybersecurity systems, related networks and devices, or potential system vulnerabilities in such
detail as would impede the registrant’s response or remediation of the incident. 34
The Commission proposed to set the filing trigger for Item 1.05 as the date the registrant
determines that a cybersecurity incident is material; as with all other Form 8-K items, the
proposed filing deadline would be four business days after the trigger. 35 To protect against any
inclination on the part of a registrant to delay making a materiality determination with a view
toward prolonging the filing deadline, the Commission proposed adding Instruction 1 to Item
1.05 requiring that “a registrant shall make a materiality determination regarding a cybersecurity
incident as soon as reasonably practicable after discovery of the incident.” 36
The Commission affirmed in the Proposing Release that the materiality standard
registrants should apply in evaluating whether a Form 8-K would be triggered under proposed
Item 1.05 would be consistent with that set out in the numerous cases addressing materiality in
the securities laws, including TSC Industries, Inc. v. Northway, Inc., 37 Basic, Inc. v. Levinson, 38
and Matrixx Initiatives, Inc. v. Siracusano, 39 and likewise with that set forth in 17 CFR 230.405
(“Securities Act Rule 405”) and 17 CFR 240.12b-2 (“Exchange Act Rule 12b-2”). That is,

information is material if “there is a substantial likelihood that a reasonable shareholder would
consider it important” 40 in making an investment decision, or if it would have “significantly
altered the ‘total mix’ of information made available.” 41 “Doubts as to the critical nature” of the
relevant information should be “resolved in favor of those the statute is designed to protect,”
namely investors. 42
The Commission explained that the timely disclosure of the information required by
proposed Item 1.05 would enable investors and other market participants to assess the possible
effects of a material cybersecurity incident on the registrant, including any short- and long-term
financial effects or operational effects, resulting in information useful for their investment
decisions. 43 Aligning the deadline for Item 1.05 with that of the other Form 8-K items would, the
Commission maintained, significantly improve the timeliness of cybersecurity incident
disclosures as well as standardize those disclosures. 44 The Commission did not propose to
provide a reporting delay in cases of ongoing internal or external investigations of cybersecurity
incidents. 45 Nevertheless, the Proposing Release requested comment on whether to allow a delay
in reporting where the Attorney General determines that a delay is in the interest of national
security. 46

2. Comments
Proposed Item 1.05 received a significant amount of feedback from commenters. Some
commenters supported Item 1.05 as proposed, 47 saying that the current level of disclosure on
cybersecurity incidents is inadequate to meet investor needs, and Item 1.05 would remedy this
inadequacy by effectuating the disclosure of decision-useful information. 48 One commenter also
anticipated that Item 1.05 would reduce the risk of insider trading by shortening the time
between discovery of an incident and public disclosure. 49
Other commenters opposed proposed Item 1.05, for several reasons. Some commenters
said that if proposed Item 1.05 were to result in disclosure while an incident is still ongoing, it
would tip off the threat actor and thus make successful neutralization of the incident more
difficult. 50 Commenters also expressed concern that public notice of a vulnerability could draw
attacks from other threat actors who were previously unaware of the vulnerability; and such
attacks could target the disclosing registrant or other companies with the same vulnerability,
particularly if the vulnerability is with a third-party service provider used by multiple

companies. 51 Some of these commenters objected specifically to the requirement in Item 1.05 to
disclose whether remediation has occurred, stating that this information could assist threat actors
in their targeting or invite further targeted attacks, 52 while others more generally stated that the
Item 1.05 disclosure would be overly detailed, such that it would give a road map to threat actors
for planning attacks. 53 One commenter argued that the prospect of possibly having to file an
Item 1.05 Form 8-K could chill threat information sharing within industries, because companies
would fear that any cybersecurity risk information they share could later be used to question their
disclosure decisions. 54
Some of the commenters that disagreed with the level of disclosure required by proposed
Item 1.05 recommended that the Commission narrow the disclosure requirements of the rule.
For example, one such commenter advised dropping the proposed requirement to disclose “when
the incident was discovered,” arguing that this detail may cause confusion, particularly where an
incident was detected some time ago but a significant aspect rendering it material surfaced only
recently. 55 Another commenter opined that “whether the registrant has remediated or is currently
remediating the incident” is duplicative of “whether it is ongoing,” so either of the two could be

eliminated. 56 One commenter contended that a materiality filter should be added to the details
required by Item 1.05, such that companies would have to disclose only details that themselves
are material, rather than immaterial details of a material incident. 57
By contrast, there were also commenters that recommended expanding the disclosure
requirements in the proposed rule. In this regard, some commenters recommended requiring that
registrants disclose asset losses, intellectual property losses, and the value of business lost due to
the incident. 58 Other suggestions included requiring that incidents be quantified as to their
severity and impact via standardized rating systems, and that registrants disclose how they
became aware of the incident, as this may shed light on the effectiveness of a company’s
cybersecurity policies and procedures. 59 Additionally, commenters suggested banning trading by
insiders during the time between the materiality determination and disclosure of the incident. 60
Commenters provided reactions to the application of Item 1.05 to incidents connected
with third-party systems. A number of commenters contended that registrants should be exempt
from having to disclose cybersecurity incidents in third-party systems they use because of their
reduced control over such systems. 61 Similarly, several commenters advocated for a safe harbor
for information disclosed about third-party systems, given registrants’ reduced visibility into
such systems. 62 A few commenters suggested a longer reporting timeframe for third-party

incidents, because the registrant may be dependent on the third party for information (which may
not be provided in a timely manner), and to avoid harm to other companies reliant on the same
third party. 63 Commenters also recommended that Item 1.05 be phased in over a longer period of
time with respect to third-party incidents, to give registrants time to develop information sharing
processes with their third-party service providers. 64
Commenters also requested guidance or otherwise raised concerns where the proposed
requirements might trigger disclosures by third-party service providers. A commenter requested
clarity on whether an incident should be disclosed by the third-party service provider registrant
that owns the affected system or the customer registrant that owns the affected information, or
both. 65 And two commenters argued that third-party service providers should simply pass along
information to their end customers, who would then make their own materiality determination
and disclose accordingly; this should particularly be the case, a commenter said, where an attack
on a third-party data center results in a data breach for an end customer but does not affect the
services the data center provides. 66
The proposed timing of incident disclosure also received a significant level of public
comment. For example, a few commenters said the level of detail required by Item 1.05 is
impractical to produce in the allotted time. 67 Other commenters said that the proposed deadline
would lead to the disclosure of tentative, unclear, or potentially inaccurate information that is not

decision-useful to investors, 68 resulting in the market mispricing the underlying securities. 69
Commenters also argued that Item 1.05 is qualitatively different from all other Form 8-K items
in that the trigger for Item 1.05 is largely outside the company’s control. 70 Some commenters
worried the proposed deadline would lead to disclosure of “false positives,” that is, incidents that
appear material at first but later on with the emergence of more information turn out not to be
material. 71
Commenters suggested a range of alternative reporting deadlines for Item 1.05. A
common suggestion was to modify the measurement date from the determination of materiality
to another point in the lifecycle of the incident when the incident is no longer a threat to the
registrant—commenters variously termed this as “containment,” “remediation,” “mitigation,”
and comparable terms. 72 One commenter recommended conditioning a reporting delay on the
registrant being actively engaged in containing the incident and reasonably believing that
containment can be completed in a timely manner. 73 Similarly, several commenters
recommended that the rule allow for a delay in providing Item 1.05 disclosure based on a
registrant’s assessment of the potential negative consequences of public disclosure, using a

variety of measures they suggested. 74 Another suggestion was to replace the proposed deadline
with an instruction to disclose material incidents “without unreasonable delay.” 75
Some commenters recommended instead increasing the number of days between the
reporting trigger and the reporting deadline. A few commenters recommended adding one
business day to make the deadline five business days; 76 one noted this would result in every
registrant having at least a full calendar week to gather information and prepare the Form 8-K. 77
Another commenter recommended a deadline of 15 business days, along with a cure period to
allow registrants a defined period of time to fix potential reporting mistakes. 78 A few
commenters recommended a 30-day deadline, 79 with their choice of 30 days tending to be a
proxy for some other factor, such as containment or remediation, 80 or state notification
requirements. 81

(stating delay should be permitted where disclosure “would exacerbate injury to the company and/or its
shareholders”); SIFMA (advocating a “‘responsible disclosure’ exception” that applies “where disclosure of a
cyber incident or vulnerability could have a more damaging effect than delayed disclosure”); Wilson Sonsini
(stating “the Commission should allow board members to decide to delay reporting if doing so could cause
material harm to the company”).

of incidents can be contained and mitigated within that time frame [30 days]”).

with data breach disclosure requirements at the state level”); Hunton (“[w]hile state data breach notification
laws vary from state to state, 30 days from the cybersecurity incident is the earliest date any state requires that
notification to affected persons be made”).

21

Several commenters recommended addressing the timing concerns by replacing current
reporting on Form 8-K with periodic reporting on Forms 10-Q and 10-K, to allow additional time
to assess an incident’s impact before reporting to markets. 82 In this vein, one commenter likened
cybersecurity incident disclosure to the disclosure of legal proceedings under Regulation S-K
Item 103. 83
A few commenters recommended instead that the materiality trigger be replaced with a
quantifiable trigger; for example, an incident implicating a specified percentage of revenue, or
the costs of an incident exceeding a specified benchmark, could trigger disclosure. 84 Other
commenters advocated for the disclosure trigger to be tied to any legal obligation that forces a
registrant to notify persons outside the company. 85
Commenters also recommended a number of exceptions to the filing deadline. The most
common recommendation was to include a provision allowing for delayed filing where there is
an active law enforcement investigation or the disclosure otherwise implicates national security
or public safety. 86 A representative comment in this vein advanced a provision whereby
registrants may “delay reporting of a cybersecurity incident that is the subject of a bona fide

investigation by law enforcement,” because such “delay in reporting may not only facilitate such
an investigation, it may be critical to its success.” 87
In calling for a law enforcement delay, associations for industries in critical sectors
emphasized the national security implications of public cybersecurity incident disclosure. For
example, one association explained that disclosure “may alert malicious actors that we have
uncovered their illegal activities in circumstances where our defense and intelligence agencies
wish to keep that information secret.” 88 Likewise, another association pointed out that, in its
industry, companies “are likely to possess some of the nation’s most critical confidential
information, including cybersecurity threat information furnished by government entities, such as
the Federal Bureau of Investigation (FBI), the Department of Homeland Security (DHS), and the
National Security Agency (NSA),” and therefore, disclosure may not be possible. 89
Commenters largely advocated for “a broad law enforcement exception that applies not
only in the interest of national security but also when law enforcement believes disclosure will
hinder their efforts to identify or capture the threat actor.” 90 Many commenters that responded to
the Commission’s request for comment regarding a provision whereby the Attorney General
determines that a delay is in the interest of national security indicated that such a provision
should be more expansive and extend to other law enforcement authorities. 91 One of these
commenters questioned whether the Attorney General would opine on matters “that are under the
ambit of other Federal agencies, such as the Department of Homeland Security, Department of

State and the Department of Defense.” 92 Another commenter pointed out that “the Department
of Justice is not the primary, or even the lead, organization in the Federal Government for
cybersecurity response, rather the Department of Homeland Security’s Cybersecurity and
Infrastructure Security Agency is often the first call that companies make,” while “[f]or defense
contractors, the Department of Defense is likely to have the highest interest in the timing of an
announcement.” 93 For the financial industry specifically, one suggestion was to permit a delay if
the Federal Reserve, Federal Deposit Insurance Corporation, or Office of the Comptroller of the
Currency finds that disclosure would compromise the safety or soundness of the financial
institution or of the financial system as a whole. 94
Some commenters specifically urged that state law enforcement be included within any
delay provision, 95 and one commenter appeared to contemplate inclusion of foreign law
enforcement. 96 A few commenters advocated for a confidential reporting system, whereby a
registrant would initially file a nonpublic report with the Commission while a law enforcement
investigation is ongoing, and then unseal the report upon the investigation’s completion. 97
A number of commenters provided feedback regarding proposed Instruction 1, which
would have directed registrants to make their materiality determination regarding an incident “as

92

See letter from Hunton. This commenter also questioned whether law enforcement would be inclined to
provide a written determination, particularly within four business days, because in its experience with State data
breach laws, “the relevant state and federal law enforcement agencies seldom (if ever) provide written
instructions when the relevant exception comes into play.”

soon as reasonably practicable after discovery of the incident.” Several commenters
recommended removing the instruction altogether as, in their view, it would place unnecessary
pressure on companies to make premature determinations before they have sufficient
information. 98 Other commenters stated that the instruction is too ambiguous for registrants to
ascertain whether they have complied with it. 99 Conversely, one commenter advised the
Commission not to provide further guidance on the meaning of “as soon as reasonably
practicable,” explaining that doing so would interfere with each registrant’s individual
assessment of what is practicable given its specific context, resulting in pressure to move more
quickly than may be appropriate. 100 Another commenter likewise found that “as soon as
reasonably practicable” is a “reasonable approach” that “provides public companies with the
appropriate degree of flexibility to conduct a thorough assessment while ensuring that the
markets get timely and relevant information.” 101 One commenter recommended a safe harbor for
actions and determinations made in good faith to satisfy Instruction 1 that later turn out to be
mistaken. 102
In response to a request for comment in the Proposing Release, several commenters
recommended registrants be permitted to furnish rather than file an Item 1.05 Form 8-K, so that
filers of an Item 1.05 Form 8-K would not be subject to liability under Section 18 of the
Exchange Act. 103 A significant number of commenters also endorsed the proposal to amend 17

CFR 240.13a-11(c) (“Rule 13a-11(c)”) and 17 CFR 240.15d-11(c) (“Rule 15d-11(c)”) under the
Exchange Act to include Item 1.05 in the list of Form 8-K items eligible for a limited safe harbor
from liability under Section 10(b) or 17 CFR 240.10b-5 (“Rule 10b-5”) under the Exchange
Act. 104 Likewise, the proposal to amend General Instruction I.A.3.(b) of Form S-3 and General
Instruction I.A.2 of Form SF-3 to provide that an untimely filing on Form 8-K regarding new
Item 1.05 would not result in loss of Form S-3 or Form SF-3 eligibility received much support. 105
Finally, a number of commenters averred that Item 1.05 would conflict with other
Federal and state cybersecurity reporting or other regulatory regimes. For example, one
commenter stated Item 1.05 would counteract the goals of CIRCIA by requiring public
disclosure of information the act would keep confidential, and went on to assert that CIRCIA
was intended as the primary means for reporting incidents to the Federal Government. 106 Also
related to CIRCIA, a number of commenters urged harmonization of the Commission’s proposal
with forthcoming regulations expected from CISA pursuant to CIRCIA. 107 Several commenters
alleged Item 1.05 would conflict with rules the Department of Health and Human Services
(“HHS”) has adopted pursuant to the Health Insurance Portability and Accountability Act
(“HIPAA”) regarding the reporting of private health information breaches. 108 A few commenters
likewise said Item 1.05 would conflict with the reporting regime set forth in Federal
Communications Commission (“FCC”) regulations for breaches of customer proprietary network

information. 109 Conflicts were also alleged with regulations and programs of the Department of
Defense (“DOD”), 110 Department of Energy (“DOE”), 111 and Department of Homeland Security
(“DHS”). 112 Commenters called for harmonization of Item 1.05 with regulations issued by
Federal banking regulators, 113 as well as with regulations of the Federal Trade Commission
(“FTC”). 114 Some commenters noted the potential interaction between the proposed rules and
state laws. 115 One commenter noted the McCarran-Ferguson Act, which provides that a state law
preempts a Federal statute if the state law was enacted for the purpose of regulating the business
of insurance and the Federal statute does not specifically relate to the business of insurance. 116
3. Final Amendments
Having considered the comments, we remain convinced that investors need timely,
standardized disclosure regarding cybersecurity incidents materially affecting registrants’
businesses, and that the existing regulatory landscape is not yielding consistent and informative
disclosure of cybersecurity incidents from registrants. 117 However, we are revising the proposal

As the Commission has previously stated, markets rely on timely dissemination of information to accurately and
quickly value securities. Additional Form 8-K Disclosure Requirements and Acceleration of Filing Date,
Release No. 33-8400 (Mar. 16, 2004) [69 FR 15593 (Mar. 25, 2004)] (“Additional Form 8-K Disclosure
Release”). Congress recognized that the ongoing dissemination of accurate information by issuers about

27

in two important respects in response to concerns raised by commenters. First, we are narrowing
the amount of information required to be disclosed, to better balance investors’ needs and
registrants’ cybersecurity posture. And second, we are providing for a delay for disclosures that
would pose a substantial risk to national security or public safety, contingent on a written
notification by the Attorney General, who may take into consideration other Federal or other law
enforcement agencies’ findings.
As described above, commenters’ criticisms of Item 1.05 generally arose from two
aspects of the proposal: (1) the scope of disclosure; and (2) the timing of disclosure. With
respect to disclosure scope, we note in particular commenter concerns that the disclosure of
certain details required by proposed Item 1.05 could exacerbate security threats, both for the
registrants’ systems and for systems in the same industry or beyond, and could chill threat
information sharing within industries. We agree that a balancing of concerns consistent with our
statutory authority is necessary in crafting Item 1.05 to avoid empowering threat actors with
actionable information that could harm a registrant and its investors. However, we are not
persuaded, as some commenters suggested, 118 that we should forgo requiring disclosure of the
existence of an incident while it is ongoing to avoid risks, such as the risk of tipping off threat
actors. Some companies already disclose material cybersecurity incidents while they are
ongoing and before they are fully remediated, but the timing, form, and substance of those
disclosures are inconsistent. Several commenters indicated both that investors look for
information regarding registrants’ cybersecurity incidents and that current disclosure levels are
themselves and their securities is essential to the effective operation of the markets, and specifically recognized
the importance of current reporting in this regard by requiring that “[e]ach issuer reporting under Section 13(a)
or 15(d) … 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.” 15 U.S.C. 78m(l).

inadequate to their needs in making investment decisions. 119 In addition, we note below in
Section IV evidence showing that delayed reporting of cybersecurity incidents can result in
mispricing of securities, and that such mispricing can be exploited by threat actors, employees,
related third parties, and others through trades made before an incident becomes public. 120
Accordingly, we believe it is necessary to adopt a requirement for uniform current reporting of
material cybersecurity incidents.
To that end, and to balance investors’ needs with the concerns raised by commenters, we
are streamlining Item 1.05 to focus the disclosure primarily on the impacts of a material
cybersecurity incident, rather than on requiring details regarding the incident itself. The final
rules will require the registrant to “describe the material aspects of the nature, scope, and timing
of the incident, and the material impact or reasonably likely material impact on the registrant,
including its financial condition and results of operations.” We believe this formulation more
precisely focuses the disclosure on what the company determines is the material impact of the
incident, which may vary from incident to incident. The rule’s inclusion of “financial condition
and results of operations” is not exclusive; companies should consider qualitative factors
alongside quantitative factors in assessing the material impact of an incident. 121 By way of
illustration, harm to a company’s reputation, customer or vendor relationships, or
competitiveness may be examples of a material impact on the company. Similarly, the
possibility of litigation or regulatory investigations or actions, including regulatory actions by

the cybersecurity incident, including both quantitative and qualitative factors”).

29

state and Federal Governmental authorities and non-U.S. authorities, may constitute a reasonably
likely material impact on the registrant.
We are not adopting, as proposed, a requirement for disclosure regarding the incident’s
remediation status, whether it is ongoing, and whether data were compromised. While some
incidents may still necessitate, for example, discussion of data theft, asset loss, intellectual
property loss, reputational damage, or business value loss, registrants will make those
determinations as part of their materiality analyses. Further, we are adding an Instruction 4 to
Item 1.05 to provide that a “registrant need not disclose specific or technical information about
its planned response to the incident or its cybersecurity systems, related networks and devices, or
potential system vulnerabilities in such detail as would impede the registrant’s response or
remediation of the incident.” While the Commission provided this assurance in the Proposing
Release, 122 we agree with some commenters that codifying it in the Item 1.05 instructions should
provide added clarity to registrants on the type of disclosure required by Item 1.05.
With respect to commenters’ questions concerning the application of Item 1.05 to
incidents occurring on third-party systems, we are not exempting registrants from providing
disclosures regarding cybersecurity incidents on third-party systems they use, nor are we
providing a safe harbor for information disclosed about third-party systems. While we
appreciate the commenters’ concerns about a registrant’s reduced control over such systems, we
note the centrality of the materiality determination: whether an incident is material is not
contingent on where the relevant electronic systems reside or who owns them. In other words,
we do not believe a reasonable investor would view a significant breach of a registrant’s data as
immaterial merely because the data were housed on a third-party system, especially as

122

Id. at 16595.

30

companies increasingly rely on third-party cloud services that may place their data out of their
immediate control. 123 Instead, as discussed above, materiality turns on how a reasonable investor
would consider the incident’s impact on the registrant.
Depending on the circumstances of an incident that occurs on a third-party system,
disclosure may be required by both the service provider and the customer, or by one but not the
other, or by neither. We appreciate that companies may have reduced visibility into third-party
systems; registrants should disclose based on the information available to them. The final rules
generally do not require that registrants conduct additional inquiries outside of their regular
channels of communication with third-party service providers pursuant to those contracts and in
accordance with registrants’ disclosure controls and procedures. This is consistent with the
Commission’s general rules regarding the disclosure of information that is difficult to obtain. 124
Turning to disclosure timing, we believe that the modifications from the proposed rules
regarding the disclosures called for by Item 1.05 alleviate many of the concerns some
commenters had regarding the proposed disclosure deadline of four business days from the
materiality determination. Because the streamlined disclosure requirements we are adopting are
focused on an incident’s basic identifying details and its material impact or reasonably likely
material impact, the registrant should have the information required to be disclosed under this
rule as part of conducting the materiality determination. For example, most organizations’
materiality analyses will include consideration of the financial impact of a cybersecurity

124

See 17 CFR 230.409 and 17 CFR 240.12b-21, which provide that information need only be disclosed insofar as
it is known or reasonably available to the registrant. Accordingly, we are not providing additional time to
comply with Item 1.05 as it relates to third-party incidents, as requested by some commenters.

31

incident, so information regarding the incident’s impact on the registrant’s financial condition
and results of operations will likely have already been developed when Item 1.05 is triggered. 125
Thus, we believe that the four business day timeframe from the date of a materiality
determination will be workable.
The reformulation of Item 1.05 also addresses the concern among commenters that the
disclosure may be tentative and unclear, resulting in false positives and mispricing in the market.
In the majority of cases, the registrant will likely be unable to determine materiality the same day
the incident is discovered. The registrant will develop information after discovery until it is
sufficient to facilitate a materiality analysis. 126 At that point, we believe investors are best served
knowing, within four business days after the materiality determination, that the incident occurred
and what led management to conclude the incident is material. While it is possible that
occasionally there may be incidents that initially appear material but developments after the
filing of the Item 1.05 Form 8-K reveal to be not material, the alternative of delaying disclosure
beyond the four business day period after a materiality determination has the potential to lead to
far more mispricing and will negatively impact investors making investment and voting
decisions without the benefit of knowing that there is a material cybersecurity incident.
Commenters posited an array of alternative deadlines for the Item 1.05 Form 8-K, as
recounted above. We are not persuaded by commenters’ arguments that disclosure should be
delayed until companies mitigate, contain, remediate, or otherwise diminish the harm of the
incident, because, as discussed above, Item 1.05 does not require disclosure of the types of
125

To the extent any required information is not determined or is unavailable at the time of the required filing,
Instruction 2 to Item 1.05, as adopted, directs the registrant to include a statement to this effect in the Form 8-K
and then file a Form 8-K amendment containing such information within four business days after the registrant,
without unreasonable delay, determines such information or within four business days after such information
becomes available. See infra Section II.B.3.

126

As discussed below, registrants should develop such information without unreasonable delay.

32

details that have the potential to be exploited by threat actors, but rather focuses on the incident’s
material impact or reasonably likely material impact on the registrant. While there may be, as
commenters noted, some residual risk of the disclosure of an incident’s existence tipping off
threat actors, such risk is justified, in our view, by investors’ need for timely information, and
similar risk already exists today with some companies’ current cybersecurity incident disclosure
practices. We are also not persuaded that Item 1.05 is sufficiently different from other Form 8-K
items such that deviating from the form’s four business day deadline following the relevant
trigger would be indicated. While some commenters argued that Item 1.05 is qualitatively
different from all other Form 8-K filings in that its trigger is largely outside the company’s
control, we disagree because other Form 8-K items may also be triggered unexpectedly, such as
Item 4.01 (Changes in Registrant’s Certifying Accountants) and Item 5.02 (Departure of
Directors or Principal Officers). And as compared to those items, the information needed for
Item 1.05 may be further along in development when the filing is triggered, whereas, for
example, a company may have no advance warning that a principal officer is departing.
With respect to the five business day deadline suggested by a few commenters to allow
registrants a full calendar week from the materiality determination to the disclosure, we note that
in the majority of cases registrants will have had additional time leading up to the materiality
determination, such that disclosure becoming due less than a week after discovery should be
uncommon. More generally with respect to the various alternative timing suggestions, we
observe that the Commission adopted the uniform four business day deadline in 2004 to simplify
the previous bifurcated deadlines, and we find commenters have not offered any compelling

33

rationale to return to bifurcated deadlines. 127 Form 8-K provides for current reporting of events
that tend to be material to investor decision-making, and we see no reason to render the reporting
of Item 1.05 less current than other Form 8-K items.
In the Proposing Release, the Commission requested comment on whether to allow
registrants to delay filing an Item 1.05 Form 8-K where the Attorney General determines that a
delay is in the interest of national security. 128 In response to comments, we are adopting a delay
provision in cases where disclosure poses a substantial risk to national security or public safety.
Pursuant to Item 1.05(c), a registrant may delay making an Item 1.05 Form 8-K filing if the
Attorney General determines that the disclosure poses a substantial risk to national security or
public safety and notifies the Commission of such determination in writing. 129 Initially,
disclosure may be delayed for a time period specified by the Attorney General, up to 30 days
following the date when the disclosure was otherwise required to be provided. The delay may be
extended for an additional period of up to 30 days if the Attorney General determines that
disclosure continues to pose a substantial risk to national security or public safety and notifies
the Commission of such determination in writing.
In extraordinary circumstances, disclosure may be delayed for a final additional period of
up to 60 days if the Attorney General determines that disclosure continues to pose a substantial
risk to national security and notifies the Commission of such determination in writing. We are

129

We note that the delay provision we are adopting does not relieve a company’s obligations under Regulation FD
or with respect to the securities laws’ antifraud prohibitions that proscribe certain insider trading, including
Exchange Act Section 10(b). Under Regulation FD, material nonpublic information disclosed to any investor,
for example, through investor outreach activities, would be required to be disclosed publicly, subject to limited
exceptions. See 17 CFR 243.100 et seq.

34

providing for the final additional delay period in recognition that, in extraordinary circumstances,
national security concerns may justify additional delay beyond that warranted by public safety
concerns, due to the relatively more critical nature of national security concerns. Beyond the
final 60-day delay, if the Attorney General indicates that further delay is necessary, the
Commission will consider additional requests for delay and may grant such relief through
Commission exemptive order. 130
We have consulted with the Department of Justice to establish an interagency
communication process to allow for the Attorney General’s determination to be communicated to
the Commission in a timely manner. The Department of Justice will notify the affected
registrant that communication to the Commission has been made, so that the registrant may delay
filing its Form 8-K.
We agree with commenters that a delay is appropriate for the limited instances in which
public disclosure of a cybersecurity incident may cause harm to national security or public
safety. The final rules appropriately balance such security concerns against investors’
informational needs. In particular, the provision’s “substantial risk to national security or public
safety” bases are sufficiently expansive to ensure that significant risks of harm from disclosure
may be protected against, while also ensuring that investors are not denied timely access to
material information. 131 With respect to commenters who recommended that other Federal

130

Any exercise of exemptive authority in these circumstances would need to meet all of the standards of Section
36 of the Exchange Act. Furthermore, Item 1.05 of Form 8-K in no way limits the Commission’s general
exemptive authority under Section 36.

131

The delay provision for substantial risk to national security or public safety is separate from Exchange Act Rule
0-6, which provides for the omission of information that has been classified by an appropriate department or
agency of the Federal Government for the protection of the interest of national defense or foreign policy. If the
information a registrant would otherwise disclose on an Item 1.05 Form 8-K or pursuant to Item 106 of
Regulation S-K or Item 16K of Form 20-F is classified, the registrant should comply with Exchange Act Rule
0-6.

35

agencies and non-Federal law enforcement agencies also be permitted to trigger a delay or who
argued that other agencies may be the primary organization in the Federal Government for the
response, we note that the rule does not preclude any such agency from requesting that the
Attorney General determine that the disclosure poses a substantial risk to national security or
public safety and communicate that determination to the Commission. However, we believe that
designating a single law enforcement agency as the Commission’s point of contact on such
delays is critical to ensuring that the rule is administrable.
Turning to other timing-related issues raised by commenters, we are not adopting
commenters’ suggestion to replace Item 1.05 with periodic reporting of material cybersecurity
incidents on Forms 10-Q and 10-K because such an approach may result in significant variance
as to when investors learn of material cybersecurity incidents. Based on when an incident occurs
during a company’s reporting cycle, the timing between the materiality determination and
reporting on the next Form 10-Q or Form 10-K could vary from a matter of months to a matter of
weeks or less. For example, if two companies experience a similar cybersecurity incident, but
one determines the incident is material early during a quarterly period and the other makes such
determination at the end of the quarterly period, commenters’ suggested approach would have
both companies report the incident around the same time despite the first company having
determined the incident was material weeks or months sooner, which would result in a
significant delay in this information being provided to investors. Such variance would therefore
reduce comparability across registrants and may put certain registrants at a competitive
disadvantage.
We also decline to use a quantifiable trigger for Item 1.05 because some cybersecurity
incidents may be material yet not cross a particular financial threshold. We note above that the

36

material impact of an incident may encompass a range of harms, some quantitative and others
qualitative. A lack of quantifiable harm does not necessarily mean an incident is not material.
For example, an incident that results in significant reputational harm to a registrant may not be
readily quantifiable and therefore may not cross a particular quantitative threshold, but it should
nonetheless be reported if the reputational harm is material. Similarly, whereas a cybersecurity
incident that results in the theft of information may not be deemed material based on quantitative
financial measures alone, it may in fact be material given the impact to the registrant that results
from the scope or nature of harm to individuals, customers, or others, and therefore may need to
be disclosed.
In another change from the proposal, and to respond to commenters’ concerns that the
proposed “as soon as reasonably practicable” language in Instruction 1 could pressure companies
to draw conclusions about incidents with insufficient information, we are revising the instruction
to state that companies must make their materiality determinations “without unreasonable delay.”
As explained in the Proposing Release, the instruction was intended to address any concern that
some registrants may delay making such a determination to avoid a disclosure obligation. 132 We
understand commenter concerns that the proposed instruction could result in undue pressure to
make a materiality determination before a registrant has sufficient information to do so, and we
recognize that a materiality determination necessitates an informed and deliberative process. We
believe the revised language should alleviate this unintended consequence, while providing
registrants notice that, though the determination need not be rushed prematurely, it also cannot
be unreasonably delayed in an effort to avoid timely disclosure. For example, for incidents that

132

Proposing Release at 16596.

37

impact key systems and information, such as those the company considers its “crown jewels,” 133
as well as incidents involving unauthorized access to or exfiltration of large quantities of
particularly important data, a company may not have complete information about the incident but
may know enough about the incident to determine whether the incident was material. In other
words, a company being unable to determine the full extent of an incident because of the nature
of the incident or the company’s systems, or otherwise the need for continued investigation
regarding the incident, should not delay the company from determining materiality. Similarly, if
the materiality determination is to be made by a board committee, intentionally deferring the
committee’s meeting on the materiality determination past the normal time it takes to convene its
members would constitute unreasonable delay. 134 As another example, if a company were to
revise existing incident response policies and procedures in order to support a delayed
materiality determination for or delayed disclosure of an ongoing cybersecurity event, such as by
extending the incident severity assessment deadlines, changing the criteria that would require
reporting an incident to management or committees with responsibility for public disclosures, or
introducing other steps to delay the determination or disclosure, that would constitute
unreasonable delay. In light of the revision to Instruction 1, we find that a safe harbor, as
suggested by some commenters, is unnecessary; adhering to normal internal practices and
disclosure controls and procedures will suffice to demonstrate good faith compliance.
Importantly, we remind registrants, as the Commission did in the Proposing Release, that

133

See National Cybersecurity Alliance, Identify Your “Crown Jewels” (July 1, 2022), available at
https://staysafeonline.org/cybersecurity-for-business/identify-your-crown-jewels/ (explaining that “[c]rown
jewels are the data without which your business would have difficulty operating and/or the information that
could be a high-value target for cybercriminals”).

134

We note that Form 8-K Item 1.05 does not specify whether the materiality determination should be performed
by the board, a board committee, or one or more officers. The company may establish a policy tasking one or
more persons to make the materiality determination. Companies should seek to provide those tasked with the
materiality determination information sufficient to make disclosure decisions.

38

“[d]oubts as to the critical nature” of the relevant information “will be commonplace” and should
“be resolved in favor of those the statute is designed to protect,” namely investors. 135
Revised Instruction 1 should also reassure registrants that they should continue sharing
information with other companies or government actors about emerging threats. Such
information sharing may not necessarily result in an Item 1.05 disclosure obligation. The
obligation to file the Item 1.05 disclosure is triggered once a company has developed information
regarding an incident sufficient to make a materiality determination, and a decision to share
information with other companies or government actors does not in itself necessarily constitute a
determination of materiality. A registrant may alert similarly situated companies as well as
government actors immediately after discovering an incident and before determining materiality,
so long as it does not unreasonably delay its internal processes for determining materiality.
As proposed, we are adding Item 1.05 to the list of Form 8-K items in General Instruction
I.A.3.(b) of Form S-3 , so that the untimely filing of an Item 1.05 Form 8-K will not result in the
loss of Form S-3 eligibility. 136 We note the significant support from commenters regarding this
proposal, and as noted in the Proposing Release, continue to believe that the consequences of the
loss of Form S-3 eligibility would be unduly severe given the circumstances that will surround
Item 1.05 disclosures. Likewise, as supported by many commenters, we are adopting as
proposed amendments to Rules 13a-11(c) and 15d-11(c) under the Exchange Act to include new
Item 1.05 in the list of Form 8-K items eligible for a limited safe harbor from liability under
Section 10(b) or Rule 10b-5 under the Exchange Act. This accords with the view the

135

Proposing Release at 16596 (quoting TSC Indus. v. Northway, 426 U.S. at 448). The Court’s opinion in TSC
Indus. has a nuanced discussion of the balance of considerations in setting a materiality standard. 426 U.S. at
448-450.

136

Because of our decision to exempt asset-backed issuers from the new rules (see infra Section II.G.1), we are not
amending Form SF-3.

39

Commission articulated in 2004 that the safe harbor is appropriate if the triggering event for the
Form 8-K requires management to make a rapid materiality determination. 137
We decline to permit registrants to furnish rather than file the Item 1.05 Form 8-K, as
suggested by some commenters. While we understand commenters’ points that reducing liability
may ease the burden on registrants, we believe that treating Item 1.05 disclosures as filed will
help promote the accuracy and reliability of such disclosures for the benefit of investors. Of the
existing Form 8-K items, only Items 2.02 (Results of Operations and Financial Condition) and
7.01 (Regulation FD Disclosure) are permitted to be furnished rather than filed. The
Commission created exceptions for those two items to allay concerns that do not pertain here.
Specifically, with respect to Item 2.02, the Commission was motivated by concerns that
requiring the information to be filed would discourage registrants from proactively issuing
earnings releases and similar disclosures. 138 Similarly, with respect to Item 7.01, the
Commission decided to allow the disclosure to be furnished to address concerns that, if required
to be filed, the disclosure could be construed as an admission of materiality, which might lead
some registrants to avoid making proactive disclosure. 139 By contrast, Item 1.05 is not a
voluntary disclosure, and it is by definition material because it is not triggered until the registrant
determines the materiality of an incident. It is thus more akin to the Form 8-K items other than
Items 2.02 and 7.01, in that it is a description of a material event that has occurred about which
investors need adequate information. Therefore, the final rules require an Item 1.05 Form 8-K to
be filed.

We are not including a new rule to ban trading by insiders during the materiality
determination time period, as suggested by some commenters. Those with a fiduciary duty or
other relationship of trust and confidence are already prohibited from trading while in possession
of material, nonpublic information. 140 And because we are adopting the four business days from
materiality determination deadline, we agree with the point raised by some commenters that the
risk of insider trading is low given the limited time period between experiencing a material
incident and public disclosure. We also note that we recently adopted amendments to 17 CFR
240.10b5-1 (“Rule 10b5-1”) that added a certification condition for directors and officers
wishing to avail themselves of the rule’s affirmative defense; specifically, if relying on the
amended affirmative defense, directors and officers need to certify in writing, at the time they
adopt the trading plan, that they are unaware of material nonpublic information about the issuer
or its securities, and are adopting the plan in good faith and not as part of a plan or scheme to
evade the insider trading prohibitions. 141 Therefore, given the timing of the incident disclosure
requirement as well as the recently adopted amendments to Rule 10b5-1, we do not find need for
a new rule banning trading by insiders during the time period between the materiality
determination and disclosure.
A number of commenters raised concerns about conflicts with other Federal laws and
regulations. Of the Federal laws and regulations that we reviewed and commenters raised
concerns with, we have identified one conflict, with the FCC’s notification rule for breaches of

140

United States v. O’Hagan, 521 U.S. 642 (1997).

141

See Insider Trading Arrangements and Related Disclosures, Release No. 33-11138 (Dec. 14, 2022) [87 FR
80362 (Dec. 29, 2022)].

41

customer proprietary network information (“CPNI”). 142 Of the remaining Federal laws and
regulations noted by commenters as presenting conflicts, our view is that Item 1.05 neither
directly conflicts with nor impedes the purposes of other such laws and regulations.
The FCC’s rule for notification in the event of breaches of CPNI requires covered entities
to notify the United States Secret Service (“USSS”) and the Federal Bureau of Investigation
(“FBI”) no later than seven business days after reasonable determination of a CPNI breach, and
further directs the entities to refrain from notifying customers or disclosing the breach publicly
until seven business days have passed following the notification to the USSS and FBI. 143 To
accommodate registrants who are subject to this rule and may as a result face conflicting
disclosure timelines, 144 we are adding paragraph (d) to Item 1.05 providing that such registrants
may delay making a Form 8-K disclosure up to the seven business day period following
notification to the USSS and FBI specified in the FCC rule, 145 with written notification to the
Commission. 146

142

47 CFR 64.2011. CPNI is defined in 47 CFR 222(h)(1) as: “(A) information that relates to the quantity,
technical configuration, type, destination, location, and amount of use of a telecommunications service
subscribed to by any customer of a telecommunications carrier, and that is made available to the carrier by the
customer solely by virtue of the carrier-customer relationship; and (B) information contained in the bills
pertaining to telephone exchange service or telephone toll service received by a customer of a carrier; except
that such term does not include subscriber list information.”

143

We note that the FCC recently proposed amending its rule; among other things, the proposal would eliminate
the seven-business day waiting period, potentially eliminating the conflict. Federal Communications
Commission, Data Breach Reporting Requirements, 88 FR 3953 (Jan. 23, 2023).

144

Commission staff consulted with FCC staff about a potential delay provision to address any conflict between
the FCC rule and the Form 8-K reporting requirements.

145

The exception we are creating does not apply to 47 CFR 64.2011(b)(3), which provides that the USSS or FBI
may direct the entity to further delay notification to customers or public disclosure beyond seven business days
if such disclosure “would impede or compromise an ongoing or potential criminal investigation or national
security.” If the USSS or FBI believes that disclosure would result in a substantial risk to national security or
public safety, it may, as explained above, work with the Department of Justice to seek a delay of disclosure.

146

Such notice should be provided through correspondence on EDGAR no later than the date when the disclosure
required by Item 1.05 was otherwise required to be provided.

42

We also considered the conflicts commenters alleged with CIRCIA. Specifically, they
stated that Item 1.05 is at odds with the goals of CIRCIA, and that it may conflict with
forthcoming regulations from CISA. The confidential reporting system established by CIRCIA
serves a different purpose from Item 1.05 and through different means; the former focuses on
facilitating the Federal Government’s preparation for and rapid response to cybersecurity threats,
while the latter focuses on providing material information about public companies to investors in
a timely manner. While CISA has yet to propose regulations to implement CIRCIA, given the
statutory authority, text, and legislative history of CIRCIA, it appears unlikely the regulations
would affect the balance of material information available to investors about public companies,
because the reporting regime CIRCIA establishes is confidential. 147 Nonetheless, the
Commission participates in interagency working groups on cybersecurity regulatory
implementation, and will continue to monitor developments in this area to determine if
modification to Item 1.05 becomes appropriate in light of future developments. 148
We also considered the HIPAA-related conflict alleged by commenters, specifically with
respect to HHS’s rule on Notification in the Case of Breach of Unsecured Protected Health
Information. That rule provides, in the event of a breach of unsecured protected health
information, for the covered entity to provide notification to affected individuals “without
unreasonable delay and in no case later than 60 calendar days after discovery of a breach.” 149 If
the breach involves more than 500 residents of a state or jurisdiction, the rule directs the covered

147

6 U.S.C. 681e.

148

Should a conflict arise in the future with CISA regulations or regulations of another Federal agency, the
Commission can address such conflict via rulemaking or other action at that time.

149

45 CFR 164.404(b). The notification must describe the breach, the types of unsecured protected health
information involved, steps the individuals should take to protect themselves, what the entity is doing to
mitigate harm and remediate, and where the individuals can seek additional information. Id.

entity to also notify prominent media outlets within the same timeframe. 150 The rule further
provides that if a company receives written notice from “a law enforcement official” requesting a
delay and specifying the length of the delay, then the company “shall … delay such notification,
notice, or posting for the time period specified by the official.” 151
We do not view Form 8-K Item 1.05 as implicated by the HHS rule. Importantly, the
HHS rule’s delay provision applies specifically to any “notification, notice, or posting required
under this subpart,” or in other words notice to affected individuals, media, and the Secretary of
HHS. 152 Such notification focuses on the consequences of the breach for the affected individuals;
for example, individuals must be told what types of protected health information were accessed,
and what steps they should take to protect themselves from harm. 153 This is different from the
disclosure required by Item 1.05, which focuses on the consequences for the company that are
material to investors, and whose timing is tied not to discovery but to a materiality
determination. The HHS rule does not expressly preclude the latter type of public disclosure, or
other potential communications companies experiencing a breach may make. Therefore, we
believe that a registrant subject to the HHS rule will not face a conflict in complying with Item
1.05. 154
We also considered the conflicts commenters alleged with regulations and programs of
DOD, DOE, DHS, the Federal banking regulatory agencies, state insurance laws, and
miscellaneous other Federal agencies or laws. We find that, while there may be some overlap of

For the same reason, the Federal Trade Commission’s Health Breach Notification rule, which is similar to
HHS’s rule, does not present a conflict either. See 16 CFR part 318.

44

subject matter, Item 1.05 neither conflicts with nor impedes the purpose of those regulations and
programs. 155 We disagree with one commenter’s assertion that cybersecurity incident disclosure
“falls squarely within the jurisdiction of state insurance commissioners” as state cybersecurity
incident reporting regulations would not pertain to the “business of insurance” as courts have
interpreted the McCarran-Ferguson Act, and the commenter did not note any particular state
insurance laws that would present a conflict. 156 With respect to Federal banking regulatory
agencies specifically, we note that, in the event they believe that the disclosure of a material
cybersecurity incident would threaten the health of the financial system in such a way that results
in a substantial risk to national security or public safety, they may, as explained above, work
with the Department of Justice to seek to delay disclosure.
It would not be practical to further harmonize Item 1.05 with other agencies’
cybersecurity incident reporting regulations, as one commenter suggested, 157 because Item 1.05
serves a different purpose—it is focused on the needs of investors, rather than the needs of
regulatory agencies, affected individuals, or the like. With respect to state insurance and privacy
laws, commenters did not provide any evidence sufficient to alter the Commission’s finding in
the Proposing Release that, to the extent that Item 1.05 would require disclosure in a situation
where state law would excuse or delay notification, we consider prompt reporting of material
cybersecurity incidents to investors critical to investor protection and well-functioning, orderly,
and efficient markets.

155

For example, one commenter alleged conflicts with DHS’s Chemical Facilities Anti-Terrorism Standards
program (“CFATS”) and with the Maritime Transportation Security Act (“MTSA”). See letter from American
Chemistry Council. Both CFATS and MTSA provide for the protection of certain sensitive information, but
neither is implicated by cybersecurity incident disclosure to the Commission.

B. Disclosures about Cybersecurity Incidents in Periodic Reports
1. Proposed Amendments
The Commission proposed to add new Item 106 to Regulation S-K to, among other
things, require updated cybersecurity disclosure in periodic reports. If a registrant previously
provided disclosure regarding one or more cybersecurity incidents pursuant to Item 1.05 of Form
8-K, proposed 17 CFR 229.106(d)(1) (Regulation S-K “Item 106(d)(1)”) would require such
registrant to disclose “any material changes, additions, or updates” on the registrant’s quarterly
report on Form 10-Q or annual report on Form 10-K. 158 In addition, proposed Item 106(d)(1)
would require disclosure of the following information:
•

Any material effect of the incident on the registrant’s operations and financial
condition;

•

Any potential material future impacts on the registrant’s operations and financial
condition;

•

Whether the registrant has remediated or is currently remediating the incident; and

•

Any changes in the registrant’s policies and procedures as a result of the
cybersecurity incident, and how the incident may have informed such changes. 159

The Commission explained that it paired current reporting under Item 1.05 of Form 8-K
with periodic reporting under 17 CFR 229.106(d) (Regulation S-K “Item 106(d)”) to balance
investors’ need for timely disclosure with their need for complete disclosure. 160 When an Item
1.05 Form 8-K becomes due, the Commission noted, a registrant may not possess complete

159

information about the material cybersecurity incident. Accordingly, under the proposed rules, a
registrant would provide the information known at the time of the Form 8-K filing and follow up
in its periodic reports with more complete information as it becomes available, along with any
updates to previously disclosed information.
The Commission also proposed 17 CFR 229.106(d)(2) (Regulation S-K “Item
106(d)(2)”) to require disclosure in a registrant’s next periodic report when, to the extent known
to management, a series of previously undisclosed individually immaterial cybersecurity
incidents become material in the aggregate. 161 The Proposing Release explained that this
requirement may be triggered where, for example, a threat actor engages in a number of smaller
but continuous related cyberattacks against the same company and collectively they become
material. 162 Item 106(d)(2) would require disclosure of essentially the same information required
in proposed Item 1.05 of Form 8-K, as follows:
•

A general description of when the incidents were discovered and whether they are
ongoing;

•

A brief description of the nature and scope of the incidents;

•

Whether any data were stolen or altered in connection with the incidents;

•

The effect of the incidents on the registrant’s operations; and

•

Whether the registrant has remediated or is currently remediating the incidents. 163

2. Comments
Reaction among commenters to proposed Item 106(d)(1) was mixed. Some wrote in
support, noting that updated incident disclosure is needed to avoid previously disclosed
information becoming stale and misleading as more information becomes available, and saying
that updates help investors assess the efficacy of companies’ cybersecurity procedures. 164 Others
took issue with specific aspects of the proposed rule. For example, some commenters stated that
the proposed requirement to disclose “any potential material future impacts” is vague and
difficult to apply, and urged removing or revising it. 165 Similarly, other commenters said that
registrants should not be required to describe progress on remediation, noting that such
information could open them up to more attacks. 166 In the same vein, one commenter suggested
that no updates be required until remediation is sufficiently complete. 167 One commenter said the
requirement to disclose changes in policies and procedures is unnecessary and overly broad, 168
and another commenter said the requirement should be narrowed to “material changes.” 169
More generally, commenters sought clarification on how to differentiate instances where
updates should be included in periodic reports from instances where updates should be filed on
Form 8-K; they found the guidance in the Proposing Release on this point “unclear.” 170 And one

See letter from PWC; accord letter from Deloitte. The Proposing Release stated: “Notwithstanding proposed
Item 106(d)(1), there may be situations where a registrant would need to file an amended Form 8-K to correct
disclosure from the initial Item 1.05 Form 8-K, such as where that disclosure becomes inaccurate or materially
misleading as a result of subsequent developments regarding the incident. For example, if the impact of the
incident is determined after the initial Item 1.05 Form 8-K filing to be significantly more severe than previously
disclosed, an amended Form 8-K may be required.” Proposing Release at 16598.

commenter argued that, regardless of where the update is filed, the incremental availability of
information would make it difficult for companies to determine when the update requirement is
triggered. 171
With respect to proposed Item 106(d)(2), a large number of commenters expressed
concern about the aggregation requirement, saying, for example, that companies experience too
many events to realistically communicate internally upward to senior management, and that
retaining and analyzing data on past events would be too costly. 172 A number of other
commenters relatedly said that, for the aggregation requirement to be workable, companies need
more guidance on the nature, timeframe, and breadth of incidents that should be collated. 173 In
this regard, one supporter of the requirement explained in its request for additional guidance that
“cybersecurity incidents are so unfortunately common that a strict reading of this section could
cause overreporting to the point that it is meaningless for shareholders.” 174
Some commenters suggested revising the rule to cover only “related” incidents. 175
Possible definitions offered for “related” incidents included those “performed by the same
malicious actor or that exploited the same vulnerability,” 176 and those resulting from “attacks on
the same systems, processes or controls of a registrant over a specified period of time.” 177
Suggestions for limiting the time period over which aggregation should occur included the

preceding one year, 178 and the preceding two years. 179 One commenter requested the
Commission clarify that a company’s Item 106(d)(2) disclosure need describe only the aggregate
material impact of the incidents, rather than describing each incident individually; the
commenter was concerned with threat actors becoming informed of a company’s vulnerabilities
through overly detailed disclosure. 180 Another commenter suggested granting registrants
additional time to come into compliance with Item 106(d)(2) after Commission adoption, so that
they can develop system functionality to retain details about immaterial incidents. 181
Commenters also wrote in support of the aggregation requirement. 182 One of these
commenters stated that aggregation is needed especially where an advanced persistent threat
actor 183 seeks to exfiltrate data or intellectual property over time. 184
3. Final Amendments
In response to comments, we are not adopting proposed Item 106(d)(1) and instead are
adopting a new instruction to clarify that updated incident disclosure must be provided in a Form
8-K amendment. Specifically, we are revising proposed Instruction 2 to Item 1.05 of Form 8-K
to direct the registrant to include in its Item 1.05 Form 8-K a statement identifying any

The National Institute of Standards and Technology explains that an advanced persistent threat “is an adversary
or adversarial group that possesses the expertise and resources that allow it to create opportunities to achieve its
objectives by using multiple attack vectors, including cyber, physical, and deception. The APT objectives
include establishing a foothold within the infrastructure of targeted organizations for purposes of exfiltrating
information; undermining or impeding critical aspects of a mission, function, program, or organization; or
positioning itself to carry out these objectives in the future. The APT pursues its objectives repeatedly over an
extended period, adapts to defenders’ efforts to resist it, and is determined to maintain the level of interaction
needed to execute its objectives.” National Institute of Standards and Technology, NIST Special Publication
800-172, Enhanced Security Requirements for Protecting Controlled Unclassified Information (Feb. 2021), at 2.

information called for in Item 1.05(a) that is not determined or is unavailable at the time of the
required filing and then file an amendment to its Form 8-K containing such information within
four business days after the registrant, without unreasonable delay, determines such information
or within four business days after such information becomes available. This change mitigates
commenters’ concerns with Item 106(d)(1). In particular, under the final rules, companies will
not have to distinguish whether information regarding a material cybersecurity incident that was
not determined or was unavailable at the time of the initial Form 8-K filing should be included
on current reports or periodic reports, as the reporting would be in an amended Form 8-K; details
that commenters suggested raised security concerns, such as remediation status, are not required;
and concerns that the proposed rule was vague or overbroad have been addressed by narrowing
the required disclosure to the information required by Item 1.05(a). We also believe that use of a
Form 8-K amendment rather than a periodic report will allow investors to more quickly identify
updates regarding incidents that previously were disclosed.
We appreciate that new information on a reported cybersecurity incident may surface
only in pieces; the final rules, however, do not require updated reporting for all new information.
Rather, Instruction 2 to Item 1.05 directs companies to file an amended Form 8-K with respect to
any information called for in Item 1.05(a) that was not determined or was unavailable at the time
of the initial Form 8-K filing. Other than with respect to such previously undetermined or
unavailable information, the final rules do not separately create or otherwise affect a registrant’s
duty to update its prior statements. We remind registrants, however, that they may have a duty to
correct prior disclosure that the registrant determines was untrue (or omitted a material fact

51

necessary to make the disclosure not misleading) at the time it was made 185 (for example, if the
registrant subsequently discovers contradictory information that existed at the time of the initial
disclosure), or a duty to update disclosure that becomes materially inaccurate after it is made 186
(for example, when the original statement is still being relied on by reasonable investors).
Registrants should consider whether they need to revisit or refresh previous disclosure, including
during the process of investigating a cybersecurity incident. 187
We are not adopting proposed Item 106(d)(2), in response to concerns that the proposed
aggregation requirement was vague or difficult to apply. We are persuaded by commenters that
the proposed requirement might be difficult to differentiate from Item 1.05 disclosure, or by
contrast, could result in the need for extensive internal controls and procedures to monitor all
immaterial events to determine whether they have become collectively material. The intent of
the proposed requirement was to capture the material impacts of related incidents, and prevent
the avoidance of incident disclosure through disaggregation of such related events. However,
upon further reflection, and after review of comments, we believe that the proposed requirement
is not necessary based on the scope of Item 1.05.
To that end, we emphasize that the term “cybersecurity incident” as used in the final rules
is to be construed broadly, as the Commission stated in the Proposing Release. 188 The definition
185

See Backman v. Polaroid Corp., 910 F.2d 10, 16-17 (1st Cir. 1990) (en banc) (finding that the duty to correct
applies “if a disclosure is in fact misleading when made, and the speaker thereafter learns of this”).

186

See id. at 17 (describing the duty to update as potentially applying “if a prior disclosure ‘becomes materially
misleading in light of subsequent events’” (quoting Greenfield v. Heublein, Inc., 742 F.2d 751, 758 (3d Cir.
1984))). But see Higginbotham v. Baxter Intern., Inc., 495 F.3d 753, 760 (7th Cir. 2007) (rejecting duty to
update before next quarterly report); Gallagher v. Abbott Laboratories, 269 F.3d 806, 808-11 (7th Cir. 2001)
(explaining that securities laws do not require continuous disclosure).

187

Relatedly, registrants should be aware of the requirement under Item 106(b)(2) of Regulation S-K to describe
“[w]hether any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents,
have materially affected or are reasonably likely to materially affect the registrant” (emphasis added). See infra
Section II.C.1.c.

Proposing Release at 16601.

of “cybersecurity incident” we are adopting extends to “a series of related unauthorized
occurrences.” 189 This reflects that cyberattacks sometimes compound over time, rather than
present as a discrete event. Accordingly, when a company finds that it has been materially
affected by what may appear as a series of related cyber intrusions, Item 1.05 may be triggered
even if the material impact or reasonably likely material impact could be parceled among the
multiple intrusions to render each by itself immaterial. One example was provided in the
Proposing Release: the same malicious actor engages in a number of smaller but continuous
cyberattacks related in time and form against the same company and collectively, they are either
quantitatively or qualitatively material. 190 Another example is a series of related attacks from
multiple actors exploiting the same vulnerability and collectively impeding the company’s
business materially.
