Fund Distribution and Issuer Transaction Rules

SEC rules governing mutual-fund distribution fees, issuer repurchase safe-harbor conditions, and prearranged insider trading defenses.

Fund Distribution and Issuer Transaction Rules groups three U.S. securities rules that address different transactions: mutual-fund distribution spending, issuer share repurchases, and prearranged trades by people who may later learn material nonpublic information. Similar rule numbers do not make the requirements interchangeable.

Use Rule 12b-1 for a fund’s use of assets for distribution-related expenses. Use SEC Rule 10b-18 for the nonexclusive issuer-repurchase safe harbor. Use SEC Rule 10b5-1 for the MNPI awareness standard and conditional trading-arrangement affirmative defenses.
