The Securities and Exchange Commission (“SEC”) adopted changes to Rule 35d-1 of the Investment Company Act of 1940 (“Names Rule”) on September 20, 2023.
Adopted in 2001, Rule 35d-1 under the Investment Company Act of 1940 was created to address concerns that fund names could mislead investors about the nature of a fund’s investments. The rule introduced the “80% investment policy”, requiring funds with names suggesting a particular focus (e.g., “Bond Fund,” “Tech Fund”) to invest at least 80% of their assets in the type of investments suggested by their name.
Over time, fund names began to include broader or more thematic terms (e.g., “ESG,” “Sustainable,”), which weren’t clearly covered by the original rule. The SEC recognized that investor expectations had evolved, and that a fund name could still be misleading even if they technically complied with the 2001 rule.
The SEC adopted amendments to modernize the rule and expand its scope to include names suggesting:
These changes aim to enhance transparency and investor protection by ensuring that fund names more accurately reflect their actual holdings and strategies.

A fund must adopt a policy to invest at least 80% of its assets in the type of investment suggested by its name. This now includes names that imply:
Funds must review their portfolio holdings at least quarterly to ensure compliance with the 80% policy. If a fund falls below the threshold, it must return to compliance within 90 days (for the majority of instances, e.g., portfolio drift).
A fund with an 80 percent investment policy is required to define the terms used in its name, including the criteria the fund uses to select the investments that the term describes. The rule requires that any terms used in the fund’s name that suggest an investment focus, or that the fund’s distributions are tax-exempt, must be consistent with those terms’ plain English meaning or established industry use.
Funds must maintain written records for at least six years (first two years easily accessible), including:
Whether an investment is part of the 80% basket and the rationale. The basket’s value as a percentage of total assets.
Documenting each investment included in the 80% and the basis for inclusion.
Records of when the 80% threshold is no longer met due to market drift, including the date and reason.
Documentation of the date and justification for any non-standard departure from the 80% policy.
Copies of any notices sent regarding changes to the 80% policy.
Funds must provide 60 days’ advance notice to shareholders before changing their 80% investment policy. Requirements include:
Unlisted closed-end funds and Business Development Companies (“BDCs”) cannot change their 80% policy without a majority shareholder vote, unless:
UITs must comply with the 80% investment policy only at the time of initial deposit. They are required to adopt a fundamental 80% policy but are exempt from ongoing monitoring, temporary departure provisions, and extended record-keeping beyond the initial deposit.
