What Is a Qualified Institutional Buyer (QIB)? Criteria Explained

A qualified institutional buyer (QIB) is an institution that the U.S. Securities and Exchange Commission treats as sophisticated enough to buy certain unregistered securities without the protections of the Securities Act of 1933’s registration process. The definition sits in Rule 144A. In its core form, a QIB is an entity that owns and invests on a discretionary basis at least $100 million in securities of issuers it is not affiliated with. Registered broker-dealers face a lower bar of $10 million. QIB status matters because it lets the holder buy, and resell among other QIBs, restricted securities such as private placements.

What the QIB criteria require

The definition combines two tests: the type of entity and the size of its securities portfolio.

Eligible entity types include insurance companies, registered investment companies, business development companies, small business investment companies, employee benefit plans, certain trusts, corporations, partnerships, registered investment advisers, banks, savings and loan associations, and entities owned entirely by QIBs.

The size thresholds depend on the category:

1. Most institutions: at least $100 million in securities of non-affiliated issuers, owned and invested at the entity’s discretion.
2. Registered broker-dealers: at least $10 million in securities of non-affiliated issuers.
3. Banks and savings and loan associations: the $100 million securities test plus an audited net worth of at least $25 million.

The calculation is narrower than total assets. Holdings of affiliated companies do not count, and some instruments are excluded, including bank deposit notes, certificates of deposit and swaps. A firm with $300 million on its balance sheet can still fall short if most of those assets are real estate, cash or stakes in its own subsidiaries.

The 2020 amendments

Before 2020 the list of eligible entity types was fixed, so some investors with more than $100 million in securities were shut out of Rule 144A deals because of their legal form. On August 26, 2020, the SEC amended the QIB and accredited investor definitions to fit together more closely. A new catch-all provision admits any unlisted institution that qualifies as an accredited investor and meets the $100 million test. Such entities may also be formed specifically to buy the securities being offered.

How QIBs function in Rule 144A transactions

Section 5 of the Securities Act generally requires offers and sales of securities to be registered with the SEC unless an exemption applies. Rule 144A, adopted in 1990, is a resale safe harbor from that requirement.

A typical Rule 144A deal follows these steps:

1. The issuer sells securities to one or more initial purchasers, usually investment banks, under a separate exemption such as a private placement. Rule 144A does not cover this first sale.
2. The initial purchasers resell the securities to QIBs, or to buyers they reasonably believe are QIBs. Rule 144A covers this resale.
3. QIBs can then trade the securities among themselves under the same safe harbor.

The resale must also meet several conditions:

• The buyer must be told that the seller may be relying on Rule 144A.
• The securities cannot be the same class as securities listed on a U.S. exchange.
• If the issuer does not file reports with the SEC, holders and prospective buyers can request basic financial information.

Common uses include debt and preferred stock placed by public companies, equity raised by non-reporting companies, and offerings by foreign issuers that want U.S. institutional capital without U.S. reporting obligations. The rule assumes that institutions with research staff and risk management can price these often complex, lightly disclosed securities, and that retail investors should not be exposed to them.

Hypothetical example

A regional insurance company holds $140 million in corporate bonds and Treasury securities from unrelated issuers. It also holds $60 million of stock in its own reinsurance subsidiary. Only the $140 million counts toward the test, and that clears the $100 million threshold. Insurance companies are a listed category, so the insurer qualifies as a QIB.

A manufacturer issues $500 million of unregistered notes to an investment bank, and the bank resells part of the deal to the insurer under Rule 144A. A year later, the insurer can sell those notes to a pension plan that also qualifies as a QIB, with no registration needed.

Now take a small broker-dealer with $12 million in non-affiliated securities. It qualifies under the $10 million dealer test. If it held only $8 million, it would fall short, and it could not participate as a QIB.

Limitations

• Narrow scope: QIB status opens the door to Rule 144A resales. It does not exempt anyone from anti-fraud rules or turn restricted securities into freely tradable public stock.
• Thinner liquidity: The secondary market is limited to QIBs. A buyer looking to exit has a smaller pool of counterparties than in public markets.
• Less disclosure: Rule 144A offerings come with an offering memorandum rather than an SEC-reviewed registration statement. The information burden falls on the buyer.
• Snapshot test: Status depends on current holdings. An institution whose portfolio drops below the threshold loses eligibility for new purchases.

QIB vs. related terms

Accredited investor. This is a broader category that includes individuals who meet income or net worth tests. It governs eligibility for offerings such as Regulation D private placements. Every QIB is effectively an institution of accredited-investor caliber, but most accredited investors are not QIBs.

Rule 144 vs. Rule 144A. Rule 144 sets conditions for the public resale of restricted and control securities, including a holding period, volume limits and the manner of sale. Rule 144A, by contrast, allows immediate resales, but only within the QIB market.

Qualified purchaser. This term comes from the Investment Company Act and determines who can invest in certain private funds. Its thresholds are separate from the QIB test.

FAQs

The Bottom Line

QIB status matters to institutions that want access to private placements and other restricted securities sold through Rule 144A. Qualifying depends on entity type and a narrow count of current non-affiliated holdings, so a large balance sheet alone does not guarantee eligibility. Buyers who qualify gain immediate resale rights within the QIB market but accept thinner liquidity and lighter disclosure than in public markets.
