A qualified institutional buyer, or QIB, is an institutional investor that the SEC recognizes as sophisticated enough to buy and resell restricted securities without the disclosure protections built into public markets. The core test comes from Rule 144A of the Securities Act of 1933: the institution must own and invest, on a discretionary basis, at least $100 million in securities issued by companies it is not affiliated with.1eCFR. 17 CFR 230.144A – Private Resales of Securities to Institutions Individuals cannot qualify, no matter how wealthy. The designation is reserved for institutions, and it opens the door to a large private market that most investors never touch.
Which Institutions Can Qualify
Meeting the $100 million threshold is necessary but not sufficient. The entity also has to fall into one of the categories Rule 144A lists:
- Insurance companies as defined under the Securities Act
- Registered investment companies and business development companies
- Small Business Investment Companies licensed by the SBA, and Rural Business Investment Companies
- State and local government employee benefit plans
- ERISA plans
- Trust funds whose participants are exclusively government or ERISA benefit plans
- 501(c)(3) organizations, corporations, partnerships, LLCs, and Massachusetts or similar business trusts
- Registered investment advisers
- Any institutional accredited investor not otherwise listed, provided it meets the $100 million threshold
The catch-all category and the explicit inclusion of LLCs and Rural Business Investment Companies came in through SEC amendments in 2020.2U.S. Securities and Exchange Commission. SEC Modernizes the Accredited Investor Definition Before those amendments, LLCs were not named in Rule 144A at all, an odd gap given how common the structure is in investment vehicles.
“Discretionary basis” is not a throwaway phrase. It means the institution, or an authorized fiduciary, holds independent authority to decide what to buy and sell, without direction from the seller of the securities in question.
Broker-Dealers Have a Lower Bar
Registered broker-dealers qualify at $10 million in securities of non-affiliated issuers on a discretionary basis, not $100 million.1eCFR. 17 CFR 230.144A – Private Resales of Securities to Institutions They function as market intermediaries in the 144A market, and the standard threshold would exclude most of them. One caveat: any securities held as part of an unsold allotment from a public offering do not count toward the $10 million.
Banks Face an Extra Test
Banks and savings associations must clear the standard $100 million threshold and also demonstrate an audited net worth of at least $25 million, shown in their most recent annual financial statements.1eCFR. 17 CFR 230.144A – Private Resales of Securities to Institutions The added requirement reflects the regulatory emphasis on stability for depository institutions that hold public deposits.
How the $100 Million Is Measured
The threshold is calculated at the cost of the securities, not their current market value. There is one exception: if the institution reports its holdings at market value in its financial statements and no current cost information has been published, market value is acceptable.1eCFR. 17 CFR 230.144A – Private Resales of Securities to Institutions This distinction matters. A fund sitting on $120 million in securities at market value can fall below $100 million measured at original cost, especially after a long run-up in prices.
Several categories of instruments do not count at all:
- Bank deposit notes and certificates of deposit
- Loan participations
- Repurchase agreements
- Securities subject to a repurchase agreement
- Currency, interest rate, and commodity swaps
An institution can have total assets well above $100 million yet still fail the QIB test because a large share sits in CDs, repos, or swaps. Only securities of unaffiliated issuers, measured at cost and stripped of the excluded instruments, count. Affiliated entities within the same corporate structure may aggregate their holdings to meet the threshold if the aggregation is clearly documented.
QIB Compared to Accredited Investor
The two categories often get confused, but they operate in different tiers. An individual can qualify as an accredited investor with a net worth over $1 million excluding their primary residence, or annual income over $200,000 ($300,000 with a spouse).3U.S. Securities and Exchange Commission. Accredited Investors Entities can qualify with $5 million in investments or assets, depending on structure.
QIB status is limited to institutions and requires $100 million in qualifying securities. That gap has practical consequences: Rule 144A transactions are off-limits to accredited investors who are not also QIBs. A high-net-worth individual can invest in a Regulation D private placement but cannot buy restricted securities in the 144A market.
What QIB Status Allows
Rule 144A provides a safe harbor from the Securities Act’s registration requirements, letting restricted securities be resold to QIBs without a full SEC registration.1eCFR. 17 CFR 230.144A – Private Resales of Securities to Institutions An issuer can raise hundreds of millions of dollars in days rather than the months a registered public offering typically requires.
A typical 144A transaction runs like this: the issuer sells securities to an investment bank, which immediately resells them to QIBs. The QIBs become the end holders. These securities carry a legend noting they have not been registered, but unlike other restricted securities, they can be freely resold among QIBs without any statutory holding period. That is the real value of the designation. It creates a liquid secondary market among institutional investors for securities that would otherwise be locked up.
By comparison, securities sold under Regulation D are subject to Rule 144’s holding period of six months if the issuer is a reporting company, or one year if it does not file reports with the SEC.4U.S. Securities and Exchange Commission. Rule 144 – Selling Restricted and Control Securities The 144A market sidesteps that entirely for QIB-to-QIB trades.
Which Securities Are Eligible
Not every security qualifies. Rule 144A requires that the securities offered not be fungible with a class already listed on a U.S. national securities exchange. A company cannot take its publicly traded common stock and sell additional shares through the 144A market. Eligibility is set at the time of issuance, so if a previously non-fungible class later gets listed, that does not retroactively disqualify it.
In practice, 144A offerings most often involve high-yield corporate bonds, convertible notes, and equity from foreign issuers entering the U.S. market for the first time. Foreign issuers frequently pair a Rule 144A offering with a Regulation S offering to cover investors outside the United States at the same time.
Disclosure the Issuer Owes
Skipping registration is not the same as skipping disclosure. If the issuer does not already file reports with the SEC, it must make certain information available to holders and prospective buyers on request: a brief description of its business, and its most recent audited financial statements, reasonably current (generally within 12 months of the resale for domestic issuers). Most issuers prepare an offering memorandum that pulls this together with risk factors and the terms of the securities.
How Sellers Verify QIB Status
A seller does not have to guarantee that every buyer is a QIB. The rule requires only that the seller “reasonably believes” the buyer qualifies.1eCFR. 17 CFR 230.144A – Private Resales of Securities to Institutions Reasonable belief is usually established through one of three methods:
- A QIB representation letter, in which the buyer formally attests that it meets the $100 million threshold and the entity-type requirements. This is the most common approach.
- Recent financial information, drawn from publicly available annual statements, filings with government agencies or self-regulatory organizations, or a certification from the entity’s chief financial officer.
- Published data in recognized securities manuals for well-known institutions.
The financial information must be dated within 16 months for a domestic entity or 18 months for a foreign entity. A seller has no obligation to independently verify what a buyer provides and can rely on available information showing QIB status even when more recent data exists. What it cannot do is rely on information it knows, or is reckless in not knowing, to be false. If the buyer turns out not to qualify, the safe harbor collapses and both sides face exposure under the Securities Act.
Keeping QIB Status
QIB status is not a one-time certification. Portfolios fluctuate, and if qualifying holdings drop below $100 million at cost, or if the institution loses discretionary authority over its investments, it no longer qualifies. There is no SEC registration or renewal process. Each institution monitors its own eligibility, and sellers verify it at the time of each transaction.
Most institutions handle this through an internal review tied to fiscal year-end reporting. The review typically includes a detailed schedule of qualifying securities, broken out by affiliated versus unaffiliated issuers, measured at cost, and stripped of the excluded instruments. Documenting discretionary investment authority matters too, since a change in governance or advisory arrangements can affect eligibility.
Falling below the threshold does not force an institution to unload what it already owns. It can continue to hold its existing 144A securities. What it cannot do is buy new ones, and any seller that transacts with a former QIB risks losing safe harbor protection. That is why the representation letter matters on every trade, not just the first.
