Safe Harbors for Delaying Disclosure of Inside Information

Inside information must generally be disclosed to the public as soon as reasonably practicable. Hong Kong law recognizes narrow circumstances in which immediate disclosure could prejudice legitimate corporate interests, but confidentiality is central to the delay.

The legal starting point

Part XIVA of the Securities and Futures Ordinance establishes the disclosure duty for a listed corporation. The safe harbors in section 307D are limited categories, including information relating to an incomplete proposal or negotiation, a decision or information subject to a system of confidentiality, and trade secrets. The facts and applicable statutory conditions must fit the relevant category.

Confidentiality must be maintained

A delay is not a blanket exemption. The corporation must take reasonable precautions to preserve confidentiality, and the information must not have been disclosed in a way that defeats the safe harbor. If the company learns that confidentiality has been breached, it must disclose the information as soon as reasonably practicable under the statutory framework.

Practical controls while disclosure is delayed

• Limit access to people who need the information and keep an insider list or equivalent record.
• Use confidentiality obligations and secure information channels.
• Monitor market rumors, unusual trading and potential leaks.
• Set an owner and review date for the decision to delay disclosure.
• Prepare an announcement so the company can respond promptly if confidentiality is lost.

What a safe harbor does not permit

It does not allow a company to delay because an announcement would be embarrassing, the share price might fall or management would prefer to wait. The delay must fit the statute and confidentiality must be protected. Listing Rules may also impose announcement or trading-halt requirements in particular circumstances.

The disclosure duty is the starting point

Part XIVA of the SFO requires a listed corporation to disclose inside information to the public as soon as reasonably practicable after the information has come to its knowledge. The information must be disclosed in a manner that provides equal, timely and effective access. A corporation should have procedures for escalation, verification, drafting and publication so that senior management can act quickly when information becomes specific and price-sensitive.

Safe harbour 1: disclosure prohibited by law or court order

Section 307D(1) provides a safe harbour where disclosure is prohibited by an enactment or would breach a court order. This is not the same as a confidentiality clause in a commercial contract; a contract cannot ordinarily override the statutory disclosure obligation. Identify the actual legal prohibition and its scope. If only part of the information is protected, assess whether the remaining inside information must still be disclosed.

Safe harbour 2: confidentiality plus a specified situation

For the other statutory safe harbour, the corporation must take reasonable precautions to preserve confidentiality, confidentiality must in fact be preserved, and at least one specified situation must apply. These situations include incomplete negotiations or proposals, information that is a trade secret, and circumstances concerning the provision of liquidity by a person under an agreement with the corporation. All required elements must be satisfied; a confidential label alone is not enough.

Reasonable precautions in practice

Restrict access to a need-to-know group, use project codes, keep insider lists, secure documents and electronic folders, monitor trading and rumors, remind insiders of confidentiality, and record each disclosure to advisers or counterparties. Share information externally only where the recipient needs it for corporate duties and is bound by confidentiality. These steps support the confidentiality condition but do not independently create a safe harbour if no statutory category applies.

Confidentiality lost: disclose promptly

If confidentiality is no longer preserved, the corporation generally must disclose as soon as reasonably practicable after becoming aware of the leak, subject to the statutory conditions and any protection for a failure despite reasonable monitoring and prompt publication. Rumors, unusual price movements or unauthorized circulation may require urgent reassessment. Do not wait for a convenient announcement window once the safe-harbour condition fails.

Decision-making and records

The board or designated disclosure committee should record when the information became specific, when it was assessed as inside information, which safe harbour is relied on, the supporting facts, confidentiality controls and review triggers. Set an expiry or reassessment time; negotiations evolve and a proposal may cease to be incomplete. Maintain a draft announcement so publication can happen quickly if circumstances change.

Safe harbour is not a general delay option

A corporation cannot delay because it wants to control the share price, wait for a press release, obtain more favorable financing or avoid embarrassment. If the conditions fail, the normal disclosure duty applies. A listed issuer should separately comply with the Listing Rules and consider whether trading suspension or other steps are needed while information is disseminated.

Exam checklist

Define inside information, state the “as soon as reasonably practicable” rule, identify the exact section 307D safe harbour, test each required condition, maintain confidentiality, and explain the response when confidentiality is lost. Distinguish a legal prohibition from contractual secrecy and from incomplete negotiations.

Meet the confidentiality condition continuously

The statutory safe harbour is not a permanent permission to keep information confidential. An issuer must take reasonable precautions to preserve confidentiality while relying on a qualifying ground, and it must disclose as soon as reasonably practicable if confidentiality is no longer preserved. Leaks, unusual trading, press enquiries that reveal the information, or circulation beyond the permitted group may require immediate reassessment.

Use a named deal team, restricted distribution lists, access controls, confidentiality undertakings and a record of who received the information. Those measures support the reasonable-precautions condition, but no single measure guarantees that confidentiality is preserved. The issuer should monitor market activity and rumours in context and escalate credible signs of leakage.

Document the reason for delay

The board or delegated decision-maker should record when the information became inside information, the statutory ground relied on, why immediate disclosure would be inappropriate under that ground, the precautions adopted and the next review time. For incomplete negotiations, for example, premature disclosure may prejudice the outcome; the record should explain the concrete risk and not just say “deal is sensitive.”

A decision log should be updated when facts change: negotiations become more certain, a counterparty withdraws, a regulatory condition is met, or the information reaches a new group. If the ground ceases to apply, the safe harbour ends. Disclosure should then be prepared without avoidable delay, with consistent information to the market.

Exam takeaway

First establish that the information is inside information. Then test a specific section 307D category and continued confidentiality. Once confidentiality is lost, the company must disclose as soon as reasonably practicable.
