What Is SEC Form CB/A?

SEC Form CB/A is an amendment to the Tender Offer/Rights Offering Notification Form that updates a previously filed SEC Form CB. It is used in transactions conducted under Securities Act Rules 801 or 802, or certain Exchange Act cross-border tender offer provisions.

This form is typically furnished when a filer needs to revise, supplement, or correct disclosures in the original Form CB submission during an ongoing rights offering, exchange offer, or tender offer involving a foreign private issuer with limited U.S. ownership. As with the initial submission, Form CB/A is furnished to provide notice and related information to U.S. security holders and regulators.

Form CB/A helps maintain an accurate public record for cross-border transaction materials furnished under the applicable exemption or rule. Filers may also track related submissions and amendments through Form CB/A amendments alongside other deal-related filings.

Key elements typically found in SEC Form CB/A include:

  • Name of the subject company and transaction parties
  • Rule provision(s) relied upon (e.g., Rule 801, Rule 802, or applicable Exchange Act provision)
  • Amendment number and description of changes from the prior filing
  • Cross-border ownership and eligibility statements (as applicable)
  • Exhibits and transaction documents furnished with the amendment
  • Signature and authorization details

SEC Form CB/A Filing Deadlines

SEC Form CB/A is filed on an event-driven basis when amendments or updates are needed to the information previously furnished on Form CB. Timing depends on when changes occur during the related rights offering, exchange offer, or tender offer process.
