Rule 405 Of The Securities Act Of 1933

Rule 405 of the Securities Act of 1933 provides the definition of an “accredited investor” that is used throughout federal securities law, most notably in Regulation D’s private placement exemptions. Understanding this rule is essential for anyone involved in raising capital privately, investing in start‑ups, or advising companies on compliance matters. The following article breaks down the rule’s origins, its substantive requirements, how it interacts with other exemptions, and what practitioners need to know to apply it correctly in today’s market.

Introduction

Rule 405 is a definitional provision tucked into the Securities Act of 1933 that determines who qualifies as an accredited investor. Although it does not impose substantive obligations on its own, the rule’s definition triggers the availability of several exemptions from registration, most famously those found in Regulation D (Rules 506(b) and 506(c)). Because the accredited investor status gates access to private capital markets, Rule 405 indirectly shapes fundraising strategies, investor eligibility, and the overall flow of capital to non‑public companies.

What Is Rule 405?

Rule 405 is located in 17 C.F.R. § 230.405. It reads, in part:

“Accredited investor means any person who comes within any of the following categories, or who the issuer reasonably believes comes within any of the following categories at the time of the sale of securities…”.

The rule does not create a standalone exemption; instead, it supplies the definition that other rules reference when they limit participation to accredited investors. By establishing clear thresholds—primarily based on income, net worth, or professional status—Rule 405 aims to protect less sophisticated investors while allowing capital formation among those deemed able to bear the economic risks of unregistered securities.

Why the Definition Matters

• Exemption eligibility: Many private placement exemptions (e.g., Rule 506(b) and 506(c) of Regulation D) are available only if all purchasers are accredited investors or if the offering includes a limited number of non‑accredited investors who receive specific disclosures.
• Liability shield: If an issuer relies on an exemption that requires accredited investor status, a mistaken belief about a purchaser’s qualification can jeopardize the exemption and expose the issuer to registration requirements and potential liability.
• Market efficiency: By providing a bright‑line test, Rule 405 reduces transaction costs associated with verifying investor sophistication on a case‑by‑case basis.

Key Definitions Under Rule 405

Rule 405 enumerates thirteen categories of accredited investors. The most commonly relied upon are:

1. Natural persons with income exceeding $200,000 (or $300,000 jointly with a spouse) in each of the two most recent years and a reasonable expectation of reaching the same level in the current year.
2. Natural persons with net worth over $1,000,000, either individually or jointly with a spouse, excluding the value of the primary residence.
3. Entities with total assets in excess of $5,000,000 (e.g., corporations, partnerships, LLCs, trusts) not formed for the specific purpose of acquiring the securities offered.
4. Directors, executive officers, or general partners of the issuer selling the securities.
5. Certain “knowledgeable employees” of private funds (as defined in Rule 3c‑5 under the Investment Company Act).
6. Family offices that manage at least $5,000,000 in assets and employ at least one person with accredited investor status.
7. “Spousal equivalents” who pool finances to meet the income or net worth test.

The rule also includes categories for banks, insurance companies, registered investment advisers, and certain government bodies, but the individual‑investor thresholds above are the ones most frequently encountered in practice.

How Rule 405 Fits Into Regulation D

Regulation D provides three primary exemptions from registration: Rules 504, 505 (now largely obsolete), and 506. Rule 506 is split into two sub‑rules:

• Rule 506(b): Allows an unlimited amount of capital to be raised from an unlimited number of accredited investors and up to 35 non‑accredited investors who must receive certain disclosure documents.
• Rule 506(c): Permits general solicitation and advertising, but all purchasers must be accredited investors, and the issuer must take reasonable steps to verify their accredited status.

Because Rule 506(c) hinges entirely on the accredited investor definition, Rule 405 becomes the gatekeeper for any offering that wishes to advertise publicly. Even under Rule 506(b), issuers often prefer to limit offerings to accredited investors to avoid the disclosure obligations tied to non‑accredited participants.

The “Reasonable Belief” Standard

Rule 405 includes a safe harbor: an issuer may rely on a reasonable belief that a purchaser is accredited if it obtains certain verification documents (e.g., tax returns, W‑2s, brokerage statements, or a written confirmation from a registered broker‑dealer, attorney, or CPA). This standard acknowledges that obtaining absolute proof can be burdensome while still requiring a meaningful effort to confirm eligibility.

The Accredited Investor Test in Detail

Income Test

• Individual: $200,000+ gross income for each of the last two years.
• Joint with spouse: $300,000+ gross income for each of the last two years.
• Expectation: The individual must reasonably expect to meet the same threshold in the current year.

Net Worth Test - Calculation: Total assets minus total liabilities.

• Exclusion: The value of the primary residence is not counted (a change introduced by the Dodd‑Frank Act in 2010).
• Threshold: $1,000,000+ net worth, either individually or jointly with a spouse.

Entity Test - Asset threshold: $5,000,000+ in total assets.

• Purpose limitation: The entity must not have been formed solely to acquire the securities being offered.

Professional Knowledge Test - Positions: Directors, executive officers, or general partners of the issuer.

• Knowledgeable employees: Employees of a private fund who participate in investment activities and meet certain experience criteria (often used in venture capital and hedge fund contexts).

Limitations and Exclusions

Limitations and Exclusions

The accredited investor definition, while expansive, contains critical limitations designed to prevent circumvention. Most notably, the $1 million net worth threshold explicitly excludes the equity value of the investor’s primary residence. This exclusion, mandated by the Dodd-Frank Act, requires lenders to subtract any mortgage debt exceeding the home’s fair market value from the net worth calculation, a provision often overlooked in informal assessments.

Furthermore, the “entity formed solely to acquire the securities” restriction prevents sponsors from pooling capital from otherwise non-accredited individuals into a shell entity to meet the $5 million asset test. The SEC looks through such structures, requiring the entity to have a pre-existing, legitimate business purpose independent of the offering.

For the professional knowledge test, eligibility is strictly tied to the issuer’s own directors, executive officers, or general partners. The “knowledgeable employee” provision for private funds is narrowly construed; mere employment is insufficient. Employees must have substantive involvement in investment decision-making and typically must have performed such functions for at least 12 months, as outlined in SEC guidance.

The spousal equivalent provision allows income and net worth to be combined, but it requires a genuine, ongoing spousal relationship. The SEC has cautioned against using informal cohabitation or recent marriages solely to meet thresholds, expecting documentation that demonstrates a shared financial life.

Finally, the “reasonable belief” safe harbor under Rule 405 is not a shield for negligence. Issuers must undertake verification steps proportional to the investor’s circumstances. Relying solely on a self-certified questionnaire without reviewing underlying documentation—such as tax returns for the income test or third-party valuations for the net worth test—fails to meet the “reasonable steps” standard and can trigger liability for non-compliance.

Conclusion

The accredited investor framework serves as the cornerstone of private market capital formation, balancing the SEC’s mission of investor protection with the need for efficient capital raising. Its evolution—from the original income and net worth benchmarks to the incorporation of professional knowledge and entity-based tests—reflects a regulatory recognition that sophistication can derive from sources beyond mere wealth. The nuanced limitations and verification requirements underscore that the definition is not a mere checkbox but a substantive gatekeeper. As private markets grow in scale and complexity, the accredited investor standard will continue to adapt, ensuring that the exemptions under Regulation D remain accessible to legitimate capital formation while maintaining a critical barrier against the indiscriminate solicitation of unsophisticated investors.
