Independent Directors Under NASDAQ Listing Standards

Bottom line: Under NASDAQ Listing Rule 5605(a)(2), an Independent Director is a person other than an Executive Officer or employee of the Company or any other individual having a relationship which, in the opinion of the Company's board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Qualifying requires passing two tests: (1) a subjective board determination of no interfering relationship, and (2) an objective "bright-line" test that the director falls into none of the disqualifying categories in Rule 5605(a)(2)(A)–(G). [S1] A majority of the board of every NASDAQ-listed operating company must be independent (Rule 5605(b)(1)), with heightened independence for the audit, compensation, and nominations functions — subject to defined exemptions for controlled companies, foreign private issuers, and certain non-operating issuers. [S1][S2]


1. Definition (Rule 5605(a)(2))

"Independent Director" means a person other than an Executive Officer or employee of the Company or any other individual having a relationship which, in the opinion of the Company's board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. [S1][S3]

Two structural points flow from this text:

  • Affirmative determination required. Independence is not presumed. The board must affirmatively determine that each independent director has no interfering relationship — assessed at initial listing, at least annually thereafter, and upon any change in circumstances. [S1][S3]
  • "Family Member" is defined broadly and is used throughout the disqualification tests: a person's spouse, parents, children, siblings, mothers- and fathers-in-law, sons- and daughters-in-law, brothers- and sisters-in-law, and anyone (other than domestic employees) who shares the person's home. [S1]

2. Eligibility Criteria — Who Qualifies

A director qualifies as independent only if both conditions are met:

(a) Subjective / general test — The director is not an Executive Officer or employee of the Company (or any parent or subsidiary), and the board affirmatively determines there is no relationship that would interfere with the exercise of independent judgment. This is a catch-all that reaches relationships beyond the enumerated bright-line categories. [S1][S3]

(b) Objective / bright-line test — The director falls into none of the disqualifying categories in Rule 5605(a)(2)(A)–(G) below. Most categories carry a three-year look-back — the disqualifying relationship must have ended more than three years before the determination. [S1][S2]


3. Disqualification Criteria — Who Cannot Serve

A director is not independent if any of the following applies now or within the applicable look-back period:

Rule Disqualifying relationship Look-back Threshold / notes
(A) Employment Director is, or was, employed by the Company (or a parent/subsidiary) 3 years
(B) Compensation Director or a Family Member accepted compensation from the Company exceeding $120,000 during any period of 12 consecutive months (this is the direct-compensation threshold, a different test and boundary from the (D) payments-between-entities threshold below) Within prior 3 years Excludes: (i) board/committee fees; (ii) compensation to a Family Member who is a non-executive employee; (iii) tax-qualified retirement plan benefits; (iv) non-discretionary compensation [S1][S4]
(C) Family executive Director is a Family Member of a person who is, or was, employed by the Company as an Executive Officer 3 years
(D) Business relationship Director or Family Member is a partner (other than a limited partner), controlling shareholder, or Executive Officer of an entity that made payments to, or received payments from, the Company exceeding the greater of $200,000 or 5% of the recipient's consolidated gross revenues (this is the entity-payments threshold, a different test and boundary from the (B) $120,000 direct-compensation threshold above) Current or any of past 3 fiscal years Excludes: (i) payments from investments in the Company's securities; (ii) payments under non-discretionary charitable matching programs. Only currently existing business relationships disqualify; historical ones that have ended are no longer disqualifying. [S1][S2]
(E) Compensation-committee interlock Director or Family Member is an Executive Officer of another entity on whose compensation committee any of the Company's Executive Officers serve(d) 3 years
(F) Auditor relationship Director or Family Member is a current partner of the Company's outside auditor, or was a partner/employee of that auditor who worked on the Company's audit 3 years
(G) Investment companies For a registered investment company, a director who is an "interested person" under Section 2(a)(19) of the Investment Company Act of 1940 (other than in the capacity of a board/committee member) Per 1940 Act Applies in lieu of (A)–(F) for investment companies [S1]

Audit-committee "super-independence" (Rule 5605(c) + SEC Rule 10A-3). Audit committee members must satisfy the general independence standard and a heightened standard: they may not accept any consulting, advisory, or other compensatory fee from the issuer (other than for board/committee service), and may not be an affiliated person of the issuer or any subsidiary. NASDAQ additionally bars anyone who participated in preparing the Company's (or a current subsidiary's) financial statements in the past three years, and requires every audit committee member to be able to read and understand financial statements, with at least one member being financially sophisticated. A director who satisfies Rule 10A-3 but not NASDAQ's general standard may serve on the audit committee for up to two years under the exceptional-and-limited-circumstances exception. [S5][S3]


4. Which Companies Must Have Independent Directors

General rule (Rule 5605(b)(1)): A majority of the board of directors of every NASDAQ-listed company must be Independent Directors. This applies uniformly across all three tiers — Nasdaq Global Select, Nasdaq Global, and Nasdaq Capital Markets — because corporate governance requirements are identical across tiers. [S1][S2][S6]

Beyond the majority-independent board, listed companies must maintain:

  • Audit committee (Rule 5605(c)) — at least three members, each an Independent Director who also meets the heightened Rule 10A-3 standard. [S1][S5]
  • Compensation committee (Rule 5605(d)) — at least two members, all Independent Directors (with an additional independence assessment specific to compensation committee service). [S1]
  • Director nominations (Rule 5605(e)) — nominees selected, or recommended, either by a majority of the independent directors or by a nominations committee composed solely of Independent Directors. [S1]
  • Executive sessions — the independent directors must meet in regularly scheduled executive sessions without management present. [S1]

Exemptions and phase-ins

  • Controlled companies (Rule 5615(c)) — a company in which more than 50% of the voting power for the election of directors is held by an individual, a group, or another company is exempt from the majority-independent-board requirement (5605(b)), the independent compensation committee (5605(d)), and the independent nominations requirement (5605(e)). It must still maintain a fully independent audit committee (Rule 10A-3) and hold executive sessions of independent directors. [S7][S8]
  • Foreign private issuers (IM-5615-3) — may follow home-country practice in lieu of the majority-independent-board, independent-compensation-committee, and independent-nominations requirements, but must still satisfy the Rule 10A-3 audit committee requirement (or use a home-country board of auditors meeting the equivalent) and must disclose the home-country practices followed (in the annual report/Form 20-F). [S1][S7]
  • Newly listed companies — receive a phase-in: e.g., a majority-independent board and fully independent committees generally within one year of listing, with graduated committee-member requirements in the interim. [S2]
  • Companies emerging from bankruptcy — may phase in independent nominations and compensation committees under Rule 5615(b). [S2]
  • Asset-backed issuers, certain passive issuers (e.g., unit investment trusts, Portfolio Depositary Receipts), and cooperatives — exempt because they lack a traditional board of directors. [S1]
  • Investment companies — apply the (G) "interested person" test in place of (A)–(F). [S1]

Provenance & limitations

Primary authority is NASDAQ Rule 5605(a)–(e) and its interpretive material (IM-5605, IM-5615 series), with the audit-committee overlay from SEC Rule 10A-3 (17 CFR § 240.10A-3). The dollar thresholds in the disqualification table above are the current figures in the rule text as reflected across the cited primary and practitioner sources. Definitions of "Executive Officer," "Family Member," "controlling shareholder," and "Controlled Company" carry technical meanings in Rule 5605(a) and the IM series; a specific independence determination for a named director should be confirmed against the live rulebook text, since NASDAQ periodically amends these standards.

Worked example

A director who left the Company's payroll 2 years ago is disqualified under (A) — those 2 years of elapsed time fall inside the three-year look-back window, so the look-back is not yet satisfied (2 years elapsed vs the 3-year window are different quantities, both correct). A director who resigned 4 years ago — 4 years of elapsed time now clears that same three-year look-back window — received no >$120,000 payment since (the (B) direct-compensation threshold), has no disqualifying family, business, interlock, or auditor tie, and whom the board affirmatively finds has no interfering relationship — qualifies as independent, though that same director would need to clear the stricter Rule 10A-3 affiliation/compensation tests before joining the audit committee.

Next step for a listing/governance check: (1) run each sitting director through (A)–(G) with the three-year look-back; (2) confirm the board's annual affirmative determination is documented; (3) verify committee composition (3 independent on audit, 2 on compensation); (4) if controlled or an FPI, document the exemption relied on and the required disclosures.

Independent Directors Under NASDAQ Listing Standards

Definition (Rule 5605(a)(2))

An independent director is "a person other than an Executive Officer or employee of the Company or any other individual having a relationship which, in the opinion of the Company's board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director." [S1]

Independence is not merely a checklist exercise. The board must make an affirmative determination that no disqualifying relationship exists. Even if a director clears every bright-line test, the board must still conclude that no other relationship impairs independent judgment. Conversely, stock ownership alone does not preclude a finding of independence. [S1]

"Family Member" — relevant to several disqualifiers — means spouse, parents, children, siblings, mothers- and fathers-in-law, sons- and daughters-in-law, brothers- and sisters-in-law, and anyone (other than domestic employees) who shares the person's home. [S1]


Disqualification Criteria — The Six Bright-Line Tests (Who Cannot Serve)

Under Rule 5605(a)(2)(A)–(F), the following persons shall not be considered independent [S1]:

(A) Employment Relationship

A director who is, or at any time during the past three years was, employed by the Company. (Note: employment as an interim Chair, CEO, or other executive officer for one year or less does not, by itself, disqualify the director after that employment ends.) [S1][S7]

(B) Compensation Over $120,000

A director who accepted (or has a Family Member who accepted) any compensation from the Company in excess of $120,000 during any 12-consecutive-month period within the three years preceding the independence determination. Three categories of compensation are excluded from this calculation [S1]:

Excluded Compensation
Compensation for board or board committee service
Compensation paid to a Family Member who is an employee (other than an Executive Officer) of the Company
Benefits under a tax-qualified retirement plan, or non-discretionary compensation

(C) Family Member of an Executive Officer

A director who is a Family Member of an individual who is, or at any time during the past three years was, employed by the Company as an Executive Officer. [S1]

(D) Significant Business Relationship (Interlocking Commercial Ties)

A director who is (or has a Family Member who is) a partner in, controlling Shareholder, or Executive Officer of, any organization to which the Company made, or from which the Company received, payments for property or services in the current or any of the past three fiscal years that exceed the greater of 5% of the recipient's consolidated gross revenues for that year, or $200,000. Excluded from this test [S1]:

  • Payments arising solely from investments in the Company's securities
  • Payments under non-discretionary charitable contribution matching programs

(E) Interlocking Compensation Committees

A director who is (or has a Family Member who is) employed as an Executive Officer of another entity where, at any time during the past three years, any Executive Officer of the Company served on the compensation committee of that other entity. [S1]

(F) Auditor Relationship

A director who is (or has a Family Member who is) a current partner of the Company's outside auditor, or was a partner or employee of the outside auditor who worked on the Company's audit at any time during the past three years. [S1]

(G) Investment Companies

In lieu of (A)–(F), for an investment company, a director who is an "interested person" as defined in Section 2(a)(19) of the Investment Company Act of 1940 (other than in their capacity as a board/committee member). [S1]


Additional, More Stringent Rules for Committee Service

Committee Additional Independence Requirements
Audit Committee (Rule 5605(c)) Must also satisfy SEC Rule 10A-3(b)(1) criteria — cannot accept any consulting, advisory, or other compensatory fee from the Company (beyond board/committee fees) and cannot be an affiliated person. Must have at least 3 members. Must not have participated in preparing the Company's financial statements in the past 3 years. At least one member must have financial sophistication. [S1][S8]
Compensation Committee (Rule 5605(d)) At least 2 independent members. Board must also consider: (i) the source of the director's compensation, including any consulting/advisory/compensatory fee; and (ii) whether the director is affiliated with the Company, a subsidiary, or an affiliate of a subsidiary. [S8]

Which Companies Are Required to Have Independent Directors

Companies That Must Comply

All companies listed on The Nasdaq Global Select Market, Nasdaq Global Market, or Nasdaq Capital Market must satisfy [S1][S7]:

  1. Majority Independent Board — a majority of the board must be independent directors (Rule 5605(b)(1)).
  2. Independent Audit Committee — fully independent, at least 3 members (Rule 5605(c)).
  3. Independent Compensation Committee — at least 2 independent members (Rule 5605(d)).
  4. Independent Director Oversight of Nominations — director nominees must be selected or recommended by either a majority of independent directors (voting alone) or a nominations committee comprised solely of independent directors (Rule 5605(e)).
  5. Executive Sessions — independent directors must meet regularly (at least twice per year) without management present (Rule 5605(b)(2)).

Companies Exempt From the Majority Independent Board Requirement

Exempt Entity Scope of Exemption Rule Reference
Controlled Companies (more than 50% of voting power held by an individual, group, or another company) Exempt from majority independent board (5605(b)), compensation committee (5605(d)), and nominating committee (5605(e)) requirements — but not exempt from executive sessions of independent directors (5605(b)(2)) or audit committee requirements (5605(c)) Rule 5615(c)(2) [S1][S9]
Foreign Private Issuers May follow home-country practice in lieu of Rules 5605(b), (d), and (e); must still comply with audit committee requirements (Rule 5605(c)(3)) and disclose which directors the board has determined to be independent Rule 5615(a)(3) [S5]
Limited Partnerships Exempt from majority independent board and executive sessions requirements Rule 5615(a)(4) [S2][S3]
Management Investment Companies (registered under the Investment Company Act of 1940) Exempt from majority independent board (5605(b)), compensation committee (5605(d)), and nominating committee (5605(e)) Rule 5615(a)(5) [S10]
Asset-Backed Issuers & Passive Issuers (e.g., unit investment trusts, royalty trusts, securitization vehicles) Exempt from majority independent board, audit committee, compensation committee, nominating committee, and code of conduct requirements Rule 5615(a)(1) [S10]
Companies in Bankruptcy Proceedings Certain exemptions available Rule 5615(b)(2) [S2]
IPO Companies (phase-in, not exemption) 12 months from listing date to achieve majority independent board; phased compliance for committees Rule 5615(b)(1) [S9]
Smaller Reporting Companies Must still have majority independent board and independent audit committee; compensation committee requirements are less burdensome [S2]

Key practical note: The board's independence determination is not a one-time exercise. Companies must make annual independence findings and disclose them in proxy statements (or Form 10-K/20-F for foreign private issuers) under Item 407(a) of Regulation S-K. [S1]

Definition of an Independent Director

Under NASDAQ Listing Rule 5605(a)(2), an "independent director" is defined as any person who is not an executive officer or employee of the listed company (or any of its parent or subsidiary corporations). Furthermore, the director must not have a relationship with the company that, in the opinion of the board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Independence is ultimately a qualitative determination made affirmatively by the board. However, the board cannot deem a director independent if the director falls under any of the specific "bright-line" disqualification criteria outlined below.

Disqualification Criteria (Who Cannot Serve)

A director is legally barred from being classified as independent if they meet any of the following criteria within the past three years:

  • Employment Relationship: The director was previously an employee of the company, or an immediate family member was previously an executive officer of the company.
    • Note: Employment as an interim CEO, chair, or other executive officer for one year or less will not automatically disqualify a director following that tenure.
  • Excessive Compensation: The director (or an immediate family member) received compensation from the company exceeding $120,000 in any 12-month period within the last three years.
    • This threshold excludes compensation received for board or committee service, compensation for an interim executive officer (serving ≤1 year), and generally non-compensatory benefits.
  • Auditor Relationships: The director (or an immediate family member) is a current partner of the company’s independent auditor, or was a partner/employee of the auditor who worked on the company’s audit within the last three years.
  • Interlocking Directorates: The director (or an immediate family member) is a current executive officer of another company where an executive officer of the listed company serves on that other company’s compensation committee.
  • Significant Business Relationships: The director (or an immediate family member) is a current partner, executive officer, or controlling shareholder of an entity (for-profit or nonprofit) that the listed company has made payments to, or received payments from, exceeding the greater of 5% of the recipient’s consolidated gross revenues or $200,000 in the current year or any of the past three fiscal years.
    • Exception: If the entity receiving the payments is a sole proprietorship, the threshold is capped at the $120,000 mark.

Eligibility Criteria (Who Qualifies)

To qualify as an independent director on a NASDAQ-listed board, a candidate must:

  1. Pass the Affirmative Board Determination: The board of directors must make an affirmative determination that the individual is independent. This determination is typically disclosed in the company’s annual proxy statement.
  2. Lack Material Relationships: The director must not have any commercial, industrial, banking, consulting, legal, accounting, charitable, or familial relationships with the company that the board deems material to their ability to exercise independent judgment.
  3. Meet Specific Committee Standards (if applicable): If the director is serving on the Audit Committee, they must meet stricter "super-independence" standards (e.g., no accepting consulting or advisory fees from the company other than board compensation). If serving on the Compensation Committee, the board must specifically consider the source of the director’s compensation and any affiliation with the company.

Types of Companies Required to Have Independent Directors

General Rule: All companies listed on The Nasdaq Stock Market are required to maintain a board of directors comprised of a majority of independent directors. Additionally, the Audit, Compensation, and Nominating & Governance committees must be comprised solely of independent directors.

Exemptions (Entities not required to have a majority independent board): The following categories of companies are exempt from the majority independent board requirement (though they may still be required to have independent Audit Committees and hold independent executive sessions):

  • Foreign Private Issuers (FPIs): Companies headquartered outside of the U.S. that use different governance structures.
  • Controlled Companies: Companies of which more than 50% of the voting power is held by an individual, a group, or another company (provided they disclose their status).
  • Limited Partnerships.
  • Management Investment Companies: Entities registered under the Investment Company Act of 1940.
  • Passive Investment Entities: Such as trusts, royalty trusts, and securitization vehicles.
  • Companies in Bankruptcy Proceedings.

Independent Directors Under the NASDAQ Listing Standards

1. The Definition — Nasdaq Rule 5605(a)(2)

Nasdaq's corporate-governance requirements live in the Rule 5600 Series of the Nasdaq Listing Rules. Rule 5605(a)(2) defines an "Independent Director" as:

a person other than an Executive Officer or employee of the Company or any other individual having a relationship which, in the opinion of the Company's board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

The definition therefore has two layers:

  1. A subjective board determination — the board must affirmatively determine that the director has no relationship that would interfere with independent judgment (Nasdaq's interpretive material, IM-5605, stresses the board's obligation to consider all relevant facts, including transactions between the company and the director or the director's family, employer, or affiliated entities).
  2. Objective "bright-line" disqualifications — Rule 5605(a)(2)(A)–(G) lists categories of persons who cannot be deemed independent regardless of the board's opinion.

For these tests, "Company" includes any parent or subsidiary (any entity consolidated with the company's financial statements), and "Family Member" (Rule 5605(a)(3)) means a person's spouse, parents, children and siblings — whether by blood, marriage, or adoption — or anyone residing in the person's home (other than domestic employees).

2. Who Qualifies (Eligibility Criteria)

A director is eligible to be counted as independent if all of the following hold:

  • He or she is not an Executive Officer or employee of the company (or its parent/subsidiaries);
  • He or she is not caught by any bright-line disqualifier in Rule 5605(a)(2)(A)–(G) (below); and
  • The board affirmatively determines that no other relationship — commercial, familial, charitable, or otherwise — would interfere with the exercise of independent judgment.

Two clarifications from Nasdaq's interpretive material:

  • Stock ownership alone does not disqualify. Even a substantial shareholder can be independent — ownership is not, by itself, a bar (though it matters for the "controlled company" exemption discussed in §5).
  • Board/committee fees don't count against the compensation test — directors may be paid for their board service without impairing independence.

3. Who Cannot Serve as an Independent Director (Bright-Line Disqualifications)

Under Rule 5605(a)(2), the following persons are conclusively not independent:

Rule Disqualification
5605(a)(2)(A) A director who is, or at any time during the past three years was, employed by the company (or a parent or subsidiary).
5605(a)(2)(B) A director who accepted, or whose Family Member accepted, compensation from the company exceeding $120,000 during any twelve-consecutive-month period within the three years preceding the independence determination. Exceptions: (i) compensation for board or board-committee service; (ii) compensation paid to a Family Member who is an employee (but not an executive officer) of the company; and (iii) benefits under a tax-qualified retirement plan, or other non-discretionary compensation.
5605(a)(2)(C) A director who is a Family Member of an individual who is, or at any time during the past three years was, employed by the company as an Executive Officer.
5605(a)(2)(D) A director who is, or has a Family Member who is, a partner in, a controlling shareholder of, or an executive officer of, any organization to which the company made, or from which the company received, payments for property or services in the current or any of the past three fiscal years that exceed 5% of the recipient's consolidated gross revenues for that year, or $200,000, whichever is greater. Exceptions: payments arising solely from investments in the company's securities, and payments under non-discretionary charitable-contribution matching programs.
5605(a)(2)(E) A director who is, or has a Family Member who is, employed as an executive officer of another entity where, at any time during the past three years, any of the company's executive officers served on that other entity's compensation committee (the "compensation-committee interlock" test).
5605(a)(2)(F) A director who is, or has a Family Member who is, a current partner of the company's outside auditor, or who was a partner or employee of the outside auditor and worked on the company's audit at any time during any of the past three years.
5605(a)(2)(G) For registered management investment companies (funds), tests (A)–(F) are replaced: a director is not independent if he or she is an "interested person" of the company as defined in Section 2(a)(19) of the Investment Company Act of 1940.

All the three-year look-backs run from the date of the independence determination (a former employee, for example, becomes eligible only after the three-year "cooling-off" period has fully run).

Heightened independence for committee service

  • Audit committee — members must satisfy Rule 5605(a)(2) and the SEC's Rule 10A-3(b)(1) under the Exchange Act (Sarbanes-Oxley §301): they may not accept any direct or indirect consulting, advisory, or other compensatory fee from the company (other than board fees), and may not be an "affiliated person" of the company or any subsidiary. They also must not have participated in preparing the company's financial statements during the past three years, and must be able to read and understand fundamental financial statements (Rule 5605(c)(2)(A)).
  • Compensation committee — under Rule 5605(d)(2)(A), the board must additionally consider all factors relevant to whether the director has a relationship material to the ability to be independent from management in compensation matters, specifically including (i) the source of the director's compensation (any consulting/advisory fees paid by the company) and (ii) any affiliation with the company or its subsidiaries/affiliates.

4. Where Independent Directors Are Required (What the Rules Mandate)

For companies subject to the full 5600 Series:

  • Majority-independent board — Rule 5605(b)(1): a majority of the board must be Independent Directors, with public disclosure of which directors the board has determined to be independent. A cure period applies if a company falls out of compliance due to a vacancy or a director's loss of independence: until the earlier of the next annual meeting or one year (or 180 days if the annual meeting falls within 180 days of the event) (Rule 5605(b)(1)(A)).
  • Executive sessions — Rule 5605(b)(2): the independent directors must hold regularly scheduled meetings at which only independent directors are present (contemplated at least twice a year).
  • Audit committee — Rule 5605(c)(2)(A): at least three members, each independent under both 5605(a)(2) and SEC Rule 10A-3, with at least one member who is financially sophisticated. A narrow "exceptional and limited circumstances" exception (Rule 5605(c)(2)(B)) permits one non-independent member (who still meets Rule 10A-3) for up to two years, but that person may not chair the committee.
  • Compensation committee — Rule 5605(d)(2): a standing committee of at least two Independent Directors (with the enhanced factors noted above) and a written charter; CEO and executive-officer compensation must be determined by the committee.
  • Director nominations — Rule 5605(e): nominees must be selected or recommended either by a majority of the Independent Directors or by a nominations committee composed solely of Independent Directors.

(Rule 5605(f), the board-diversity disclosure rule, was vacated by the Fifth Circuit in December 2024 and is no longer in effect.)

5. Which Companies Must Have Independent Directors — and Which Are Exempt

Baseline: every company listed on any Nasdaq tier (Global Select Market, Global Market, or Capital Market) must comply with the 5600 Series, including the majority-independent-board and independent-committee requirements, unless a specific exemption in Rule 5615 applies. The principal exemptions and accommodations:

Category (Rule 5615) Treatment
Controlled companies — Rule 5615(c): more than 50% of voting power for the election of directors held by one individual, group, or another company Exempt from the majority-independent board (5605(b)(1)), compensation committee (5605(d)), and director-nominations (5605(e)) requirements. Not exempt from the executive-session requirement (5605(b)(2)) or the audit committee requirement (5605(c)). Must disclose reliance on the exemption.
Foreign private issuers — Rule 5615(a)(3) May follow home-country practice in lieu of most 5600-Series requirements (with disclosure of each requirement not followed), but must still maintain an audit committee satisfying SEC Rule 10A-3.
Limited partnerships — Rule 5615(a)(4) Exempt from majority board, compensation-committee, and nominations requirements; still must have a Rule 10A-3-compliant audit committee.
Asset-backed issuers and other passive issuers; cooperatives — Rules 5615(a)(1), 5615(a)(2) Exempt from the board/committee independence requirements given their structure.
Management investment companies — Rule 5615(a)(5) Registered funds are exempt from several provisions (their governance is regulated by the Investment Company Act); the "interested person" test of 5605(a)(2)(G) applies where independence is required.
Smaller reporting companies — Rule 5605(d)(5) Reduced compensation-committee burden: a committee of at least two Independent Directors (per 5605(a)(2) only, without the enhanced compensation-committee factors) and a charter or board resolution.
Newly listing companies (IPOs) — Rule 5615(b)(1) Phase-in: one independent audit-committee member at listing, a majority within 90 days, fully independent committees and a majority-independent board within one year of listing.

Bottom line: every Nasdaq-listed operating company must have independent directors — at minimum a fully independent, three-member audit committee (a requirement that survives virtually every exemption because it is also mandated by SEC Rule 10A-3 under Sarbanes-Oxley) — and, unless it is a controlled company, foreign private issuer following home-country practice, or another Rule 5615-exempt category, it must also maintain a majority-independent board and independent compensation and nomination processes.

Definition

Under Nasdaq Rule 5605(a)(2), an Independent Director is a director who is not an executive officer or employee of the company and has no relationship that, in the board’s opinion, would interfere with the director’s independent judgment. The board must make an affirmative independence determination. Nasdaq also treats “Company” as including controlled, consolidated parents and subsidiaries for this analysis. Nasdaq Rule 5605(a)(2), IM-5605

Who Qualifies

A director may be counted as independent only if:

  • The director is not an executive officer or employee of the company.
  • The board affirmatively determines that the director has no relationship impairing independent judgment.
  • None of Nasdaq’s bright-line disqualifying relationships applies.
  • For investment companies, the director is not an “interested person” under Section 2(a)(19) of the Investment Company Act, except solely by serving on the board or a committee.
  • Mere ownership of company stock, by itself, does not preclude independence.

Who Cannot Be Counted as Independent

A director is not independent if any of the following applies:

Disqualification Nasdaq standard
Company employment The director is, or during the past 3 years was, employed by the company.
Excess compensation The director, or a family member, accepted more than $120,000 from the company in any 12-month period during the 3 years before the independence determination, excluding board/committee fees, certain non-executive family-member employee pay, tax-qualified retirement benefits, and nondiscretionary compensation.
Family tie to executive The director is a family member of someone who is, or during the past 3 years was, employed by the company as an executive officer.
Material business relationship The director, or a family member, is a partner, controlling shareholder, or executive officer of an organization that made payments to, or received payments from, the company for property or services in the current or any of the past 3 fiscal years exceeding the greater of 5% of the recipient’s consolidated gross revenues or $200,000, excluding payments from investments in the company’s securities and nondiscretionary charitable matching programs.
Compensation committee interlock The director, or a family member, is an executive officer of another entity where any company executive officer served on that entity’s compensation committee during the past 3 years.
Auditor relationship The director, or a family member, is a current partner of the company’s outside auditor, or was a partner or employee of the auditor who worked on the company’s audit during any of the past 3 years.
Investment company status For an investment company, the director is an “interested person” under the Investment Company Act.

“Family member” includes a spouse, parents, children, siblings, in-laws, and anyone sharing the person’s home other than domestic employees. Nasdaq Rule 5605(a)(2)

Companies Required to Have Independent Directors

Generally, companies listed or applying to list on Nasdaq must satisfy Nasdaq’s corporate governance rules. Nasdaq Rule 5605(b)(1) requires that a majority of the board be independent directors. Nasdaq also requires independent-director participation in executive sessions, audit committees, compensation committees, and director nominations, subject to exceptions. Nasdaq Rules 5001, 5605(b)

Key exceptions and modified rules include:

  • Controlled companies: exempt from the majority-independent-board, compensation committee, and nomination requirements, but still generally must meet audit committee independence rules.
  • Foreign private issuers: may follow home-country governance practices instead of many Nasdaq Rule 5600 requirements, with disclosure, but must maintain an audit committee satisfying Nasdaq/SEC audit committee requirements.
  • Asset-backed issuers and passive issuers: generally exempt from the majority-independent-board and committee requirements.
  • Limited partnerships: not subject to the full Rule 5600 series, but the corporate general partner must have enough independent directors to satisfy audit committee requirements.
  • Registered management investment companies: exempt from the majority-independent-board requirement, though business development companies must comply with Rule 5600.
  • Issuers listing only non-voting preferred securities, debt securities, or derivative securities: exempt from the independent-director board rules unless they also list common stock, voting preferred stock, or equivalents.
  • IPO companies, companies emerging from bankruptcy, transfers, spin-offs, and companies losing exempt status: often receive phase-in periods rather than permanent exemptions. Nasdaq Rule 5615
model: x-ai/grok-4.3

An independent director under NASDAQ listing standards is defined in Listing Rule 5605(a)(2).[1]

Definition: An “Independent Director” means a person other than an Executive Officer or employee of the Company or any other individual having a relationship which, in the opinion of the Company’s board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.[1]

The board must make an affirmative determination that no such relationship exists. Stock ownership by itself does not preclude a finding of independence.[2]

Eligibility criteria (who qualifies): A director qualifies as independent if the board affirmatively determines the individual has no relationship that would interfere with independent judgment, and the person does not fall into any of the per se disqualification categories below. This includes a principles-based assessment beyond the bright-line rules.[1]

Disqualification criteria (who cannot serve as independent): The following persons shall not be considered independent (per Rule 5605(a)(2)):[1]

  • (A) A director who is, or at any time during the past three years was, employed by the Company.
  • (B) A director who accepted or who has a Family Member who accepted any compensation from the Company in excess of $120,000 during any period of twelve consecutive months within the three years preceding the determination of independence (other than: (i) compensation for board or board committee service; (ii) compensation paid to a Family Member who is an employee (other than an Executive Officer) of the Company; or (iii) benefits under a tax-qualified retirement plan, or non-discretionary compensation).
  • (C) A director who is a Family Member of an individual who is, or at any time during the past three years was, employed by the Company as an Executive Officer.
  • (D) A director who is, or has a Family Member who is, a partner in, or a controlling Shareholder or an Executive Officer of, any organization to which the Company made, or from which the Company received, payments for property or services in the current or any of the past three fiscal years that exceed 5% of the recipient’s consolidated gross revenues for that year, or $200,000, whichever is more (other than: (i) payments arising solely from investments in the Company’s securities; or (ii) payments under non-discretionary charitable contribution matching programs).
  • (E) A director of the Company who is, or has a Family Member who is, employed as an Executive Officer of another entity where at any time during the past three years any of the Executive Officers of the Company serve on the compensation committee of such other entity.
  • (F) A director who is, or has a Family Member who is, a current partner of the Company’s outside auditor, or was a partner or employee of the Company’s outside auditor who worked on the Company’s audit at any time during any of the past three years.

“Family Member” means a person’s spouse, parents, children, and siblings, whether by blood, marriage or adoption, or anyone residing in such person’s home. Additional or more stringent independence standards apply to audit committee members (e.g., SEC Rule 10A-3(b)(1) requirements and no participation in preparing financial statements in the past three years) and compensation committee members (consideration of specific factors like source of compensation and affiliations).[3]

Which types of companies are required to have independent directors on their board? Rule 5605(b)(1) requires that a majority of the board of directors of most NASDAQ-listed companies must be comprised of Independent Directors.[1]

This applies to domestic operating companies that are not exempt. Key exemptions and exceptions include:[1]

  • Controlled companies (where more than 50% of voting power is held by an individual, group, or another company): Exempt from the majority independent board requirement (and independent oversight of director nominations and executive compensation), though they must still hold regular executive sessions of independent directors and maintain an independent audit committee. They must make certain disclosures.
  • Foreign private issuers (FPIs): May follow home country practice in lieu of the majority independent board requirement (with disclosure of non-compliance); they are not required to have a majority of independent directors but must have an audit committee meeting specific independence standards.
  • Other categories with exemptions or modified rules include certain limited partnerships, management investment companies, asset-backed issuers, passive issuers, cooperatives without publicly traded common stock, and companies emerging from bankruptcy or recently ceasing to be controlled companies (subject to phase-in periods).
  • New listings (e.g., IPOs) and certain transitions have phase-in schedules for compliance.

All NASDAQ-listed companies generally must have an audit committee of at least three members, all of whom are independent under NASDAQ Rule 5605(a)(2) plus the more stringent SEC Rule 10A-3 standards. Independent directors are also required for compensation and nominations committee functions in non-exempt companies.[1]

These standards are outlined in NASDAQ Listing Rule 5605 and related interpretations (IM-5605). Companies must disclose their independent directors and the basis for independence determinations (e.g., via proxy statements or Forms 10-K/20-F). Rules can include phase-ins or cure periods in limited circumstances, and boards have flexibility in the affirmative independence determination for relationships not covered by the bright-line tests.

Independent Directors under NASDAQ Listing Standards

Definition

Under NASDAQ Listing Rule 5605(a)(2), an "independent director" is defined as a person other than an executive officer or employee of the company, and who has no relationship that, in the opinion of the company's board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

For the purposes of this rule, "Company" includes the listed company and its relevant parent or subsidiaries. A "Family Member" includes a person's spouse, parents, children, siblings, in-laws, and anyone sharing the person's home (other than domestic employees).

Eligibility Criteria (Who Qualifies)

To qualify as an independent director on a NASDAQ-listed company's board, an individual must satisfy both subjective and objective requirements:

  1. Non-Employee Status: The individual cannot currently be an executive officer or employee of the company.
  2. Affirmative Board Determination: The board of directors must affirmatively determine that the individual has no direct or indirect relationship with the company that would impair their independent judgment.
  3. Absence of Bright-Line Disqualifiers: The individual must not trigger any of NASDAQ's objective disqualifying relationships (detailed below).
  4. Stock Ownership: Notably, ownership of company stock—even a significant amount—does not automatically preclude a finding of independence. The board evaluates stock ownership as part of the total facts and circumstances.

Disqualification Criteria (Who Cannot Serve)

NASDAQ outlines several objective "bright-line" tests. A director is automatically disqualified from being considered independent if any of the following circumstances apply:

  1. Current or Recent Employment: The director is currently employed by the company, or was employed by the company at any time during the past three years.
  2. Excessive Compensation: The director, or a family member, accepted more than $120,000 in direct compensation from the company during any 12-consecutive-month period within the past three years. (Exceptions include compensation for board/committee service, compensation paid to a family member who is a non-executive employee, and benefits under tax-qualified retirement plans).
  3. Family Member Executive Status: A family member of the director is currently employed, or was employed at any time during the past three years, as an executive officer of the company.
  4. Significant Business Relationships: The director, or a family member, is a partner, controlling shareholder, or executive officer of any organization that made payments to, or received payments from, the listed company exceeding the greater of 5% of the recipient's consolidated gross revenues or $200,000 in the current or any of the past three fiscal years.
  5. Compensation Committee Interlocks: The director, or a family member, is employed as an executive officer of another entity where any of the listed company's executive officers served on that outside entity's compensation committee at any time during the past three years.
  6. Auditor Affiliation: The director, or a family member, is a current partner of the company's outside auditor, or was a partner or employee of the outside auditor who worked on the company's audit at any time during the past three years.

(Note: Stricter independence standards apply for audit committee members under SEC Rule 10A-3, which prohibits them from accepting any consulting, advisory, or compensatory fees outside of standard board service, and from being an "affiliated person" of the company.)

Which Companies Are Required to Have Independent Directors?

General Rule

As a general rule under the NASDAQ 5600 Series, all standard operating companies listed on the NASDAQ Stock Market must have a board of directors comprised of a majority of independent directors. Furthermore, these companies must have independent director oversight over executive compensation and the director nominations process, and they must maintain an audit committee comprised solely of independent directors.

Exemptions, Phase-Ins, and Special Issuer Types

NASDAQ provides specific exemptions and alternative compliance frameworks for certain entities. Even when exempt from the majority-independent board requirement, many of these entities are still required by federal securities laws to maintain an independent audit committee.

Issuer Type NASDAQ Independent Director Requirements
Controlled Companies (Over 50% voting power held by an individual, group, or another company) Exempt from the majority-independent board, compensation committee, and nomination committee requirements. However, they must still maintain an independent audit committee.
Foreign Private Issuers May elect to follow their home country's corporate governance practices instead of NASDAQ's general rules (with required disclosures). They must still satisfy audit committee independence requirements under SEC Rule 10A-3.
Initial Public Offerings (IPOs) & Companies Emerging from Bankruptcy Granted a one-year phase-in period to achieve a fully majority-independent board and to populate fully independent committees.
Asset-Backed Issuers and Passive Issuers (e.g., unit investment trusts) Fully exempt from the majority-independent board, audit committee, compensation committee, and nominations requirements.
Cooperatives (Without a publicly traded class of common stock) Exempt from the majority-independent board and compensation/nominating committee requirements, but must comply with applicable federal audit committee requirements.
Limited Partnerships The corporate general partner is exempt from the majority-independent board requirement, but must maintain enough independent directors to satisfy the audit committee requirements.
Registered Management Investment Companies Exempt from the standard majority-independent board rules, as they are strictly governed by the distinct independence definitions ("interested person" test) within the Investment Company Act of 1940.
Debt-Only or Preferred Securities Issuers Issuers whose only listed securities are non-voting preferred securities, debt securities, or derivative securities are exempt from the majority-independent board and committee requirements.

Definition of an Independent Director under NASDAQ Listing Standards

Under NASDAQ Rule 5605(a)(2), an Independent Director is defined as:

A person other than an Executive Officer or employee of the Company or any other individual having a relationship which, in the opinion of the Company's board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

The board has an affirmative responsibility to determine that no such relationships exist. Ownership of company stock alone does not preclude a finding of independence (listingcenter.nasdaq.com).


Eligibility Criteria (Who Qualifies)

To be considered independent, a director must:

  • Not be an Executive Officer or employee of the Company;
  • Not have any relationship that, in the board's judgment, would impair their independent judgment;
  • Be affirmatively determined by the board to have no material relationship with the Company that would interfere with such independence (listingcenter.nasdaq.com).

The rule defines Family Member as a person's spouse, parents, children, siblings, mothers and fathers-in-law, sons and daughters-in-law, brothers and sisters-in-law, and anyone (other than domestic employees) who shares the person's home (listingcenter.nasdaq.com).


Disqualification Criteria (Who Cannot Serve)

A director cannot be considered independent if they fall under any of the following categories (with a three-year look-back period unless noted):

(A) Employment by the Company: A director who is, or at any time during the past three years was, employed by the Company.

(B) Compensation: A director who accepted, or whose Family Member accepted, any compensation from the Company exceeding $120,000 during any 12-month period within the past three years, other than:

  1. Compensation for board or board committee service;
  2. Compensation paid to a Family Member who is an employee (other than an Executive Officer); or
  3. Benefits under a tax-qualified retirement plan or non-discretionary compensation.

(C) Family Member of an Executive Officer: A director who is a Family Member of an individual who is, or at any time during the past three years was, employed by the Company as an Executive Officer.

(D) Business Relationships: A director (or Family Member) who is a partner, controlling shareholder, or Executive Officer of any organization to which the Company made or received payments for property or services in the current or past three fiscal years that exceed 5% of the recipient's consolidated gross revenues or $200,000, whichever is greater, other than:

  1. Payments arising solely from investments in the Company's securities; or
  2. Payments under non-discretionary charitable contribution matching programs.

(E) Interlocking Directorates: A director who is, or whose Family Member is, employed as an Executive Officer of another entity where any of the Company's Executive Officers serve on that entity's compensation committee at any time during the past three years.

(F) Auditor Relationship: A director who is, or whose Family Member is, a current partner of the Company's outside auditor, or was a partner or employee of the outside auditor who worked on the Company's audit during any of the past three years.

(G) Investment Companies: For investment companies, a director who is an "interested person" as defined in Section 2(a)(19) of the Investment Company Act of 1940 (in lieu of paragraphs A–F) (listingcenter.nasdaq.com).


Which Types of Companies Are Required to Have Independent Directors?

Under Rule 5605(b)(1), a majority of the board of directors of a NASDAQ-listed company must be comprised of Independent Directors. However, certain types of issuers are exempt from this majority independent board requirement or have modified requirements:

Type of Company Requirement / Exemption
General listed companies Must have a majority of independent directors on the board.
Controlled Companies (more than 50% voting power held by an individual, group, or company) Exempt from the majority independent board requirement, but must still hold regularly scheduled executive sessions of independent directors.
Asset-backed issuers and passive issuers (e.g., unit investment trusts without a board) Exempt from Rule 5605(b).
Limited Partnerships Generally exempt from the Rule 5600 Series, except as specifically provided.
Cooperatives (e.g., agricultural cooperatives without publicly traded common stock) Exempt from Rule 5605(b).
Management Investment Companies (registered under the Investment Company Act of 1940) Exempt from Rule 5605(b).
Issuers of only non-voting preferred securities, debt securities, or Derivative Securities Exempt from Rule 5605(b).
Foreign Private Issuers Must comply and disclose in their next annual report which directors the board has determined to be independent.
Smaller Reporting Companies Subject to the majority independent board requirement, but have specific exemptions related to compensation committee composition and charter requirements.

In addition to the board-level requirement, companies must also have independent directors serving on their audit committees (at least three members) and compensation committees (Smaller Reporting Companies must have at least two independent directors on the compensation committee) (listingcenter.nasdaq.com).

Which answer is better — the judges' verdicts

Claude Fable 5 — self-evaluation

Best answer: Claude Fable 5

This is my own answer, and I would rather not pick it — but on this question the differentiator is Rule 5605(a)(2)(G), and that tips it.

The (G) test. The codified rule contains a seventh bright-line item: for registered management investment companies, tests (A)–(F) are replaced by the "interested person" test under §2(a)(19) of the Investment Company Act. My answer, GPT-5.5 Pro, and GLM-5.2 all state this correctly. Hyperspace gets it wrong — it asserts "the codified bright-line tests run A–F" and explains away "(G)" as a mislabeled catch-all. That is a confident, boxed-and-highlighted error in an otherwise excellent answer, and on a legal-definition question a wrong claim about the rule's own structure is disqualifying for the top spot. Grok and Fugu simply omit (G), which is a lesser sin.

Otherwise Hyperspace is arguably the strongest write-up: best treatment of the parent/subsidiary scope, the IM-5605 interim-officer carve-out, the audit-committee "zero-dollar" fee standard, and the cleanest sourcing discipline (primary rule vs. law-firm summaries, with a currency caveat). If not for the (G) error it would win.

GPT-5.5 Pro is correct and complete but thinner — no per-item rule citations, lighter on committee-level standards and phase-in mechanics. Grok 4.3 quotes the rule text A–F nearly verbatim (good grounding) but misses (G) and is shallower on exemptions. Fugu Ultra has a clean exemption table but no rule-number citations and omits (G). GLM-5.2 covers (G) but its foreign-private-issuer row ("must comply and disclose") badly understates the home-country-practice exemption, and its in-law-enumerating Family Member definition tracks the pre-amendment text.

My answer's real weaknesses: (1) I cite "Rule 5605(a)(3)" for the Family Member definition — the definition sits within 5605(a)(2), so that pinpoint is likely a mis-cite; (2) two of my four sources are low-authority blogs (SecuritiesLawyer101, securities-law-blog) where Hyperspace leaned on the rulebook plus name-brand firm memos; (3) Hyperspace's caveats section (confirm live thresholds, stricter committee standards govern) is more professionally careful than anything I wrote. I win on structural correctness and coverage (cure periods, 5605(f) vacatur, smaller-reporting-company relief), not on sourcing hygiene.

GPT-5.5 Pro — self-evaluation (gpt-5.5 (codex))

Best answer: Claude Fable 5

Claude Fable 5 is best overall. It gives the correct Rule 5605(a)(2) definition, clearly separates the subjective board judgment from the bright-line disqualifiers, lists all A-G disqualification categories with thresholds and exceptions, and answers the company-scope question with the main Rule 5615 exemptions. It is also well grounded with usable citations and adds relevant committee-level independence requirements without losing focus.

My answer, GPT-5.5 Pro, is strong but a step below. It is concise, mostly correct, and directly answers all three parts of the question. Its table of disqualifiers is accurate, includes the key dollar thresholds, family-member concept, investment-company rule, and major exempt issuer categories. It also avoids overclaiming and cites Nasdaq primary rules.

Its weaknesses relative to Claude Fable 5 are mainly depth and precision. Claude gives more complete treatment of audit, compensation, nomination, executive-session, cure-period, and phase-in rules. It also explains foreign private issuers, controlled companies, limited partnerships, and IPO phase-ins with more specificity. My answer says FPIs must maintain an audit committee satisfying “Nasdaq/SEC audit committee requirements,” which is broadly right but less nuanced than explaining home-country practice and Rule 10A-3. My answer also compresses “who qualifies” into a short checklist and does not spell out Nasdaq interpretive material as clearly.

Hyperspace is the most exhaustive, but it is overbuilt for the prompt and includes at least one risky statement about business relationships: “Only currently existing business relationships disqualify; historical ones that have ended are no longer disqualifying,” which is too categorical given the current-or-past-three-fiscal-years payment test. Grok is accurate but omits the investment-company disqualifier from the main list and is thinner on issuer exemptions. Fugu is readable but uncited and makes some exemption statements too broadly. GLM is solid on the definition and disqualifiers, but its foreign private issuer treatment is misleading because FPIs may follow home-country practices for many Nasdaq governance requirements.

Overall ranking: Claude Fable 5 first, GPT-5.5 Pro second, then Hyperspace, GLM-5.2, Grok 4.3, and Fugu Ultra.

Grok 4.3 — self-evaluation

Best answer: Hyperspace

Hyperspace is the strongest overall: it is the most complete, precisely structured, and directly responsive. It opens with the exact Rule 5605(a)(2) definition, cleanly separates the subjective board test from the objective bright-line tests, presents disqualification criteria in a clear table with look-back periods and thresholds, explicitly covers heightened audit/compensation standards, and gives a full, accurate list of required companies plus every material exemption (controlled companies, FPIs, phase-ins, passive issuers, etc.). Its citations are primary-rule focused and it includes a useful worked example.

Claude Fable 5 is nearly as strong and very close in depth and accuracy. GPT-5.5 Pro and Fugu Ultra are solid but noticeably shorter on detail and table clarity. GLM-5.2 is accurate yet thinner on committee nuances and examples. Grok 4.3 (mine) is correct, concise, and covers the core definition, eligibility, disqualifiers, and exemptions with proper citations, but it is less exhaustive than the top two—no detailed table, fewer explanatory notes on thresholds/exceptions, and no worked illustration. It is fully serviceable but loses on depth and polish.

Fugu Ultra — self-evaluation

Best answer: Hyperspace

Overall Comparison & Verdict Hyperspace provides the most comprehensive, accurate, and deeply researched response, securing the top spot. It excels across all criteria: correctness, depth, grounding, and direct responsiveness. It clearly separates the subjective and objective tests, meticulously details the disqualification categories (accurately noting look-back periods and the distinct $120k and $200k/5% dollar thresholds), and thoroughly explains the exemptions. Furthermore, Hyperspace features superior grounding with precise inline citations mapped to a robust source list, and it includes a highly valuable "worked example" that demonstrates how to apply the complex look-back rules in practice.

Claude Fable 5 is a very close runner-up, offering an exceptionally clean layout, a flawless disqualification table, and highly accurate legal explanations (including a helpful note about the recently vacated board-diversity rule). However, Hyperspace's rigorous inline citations and practical application section give it a slight edge in depth.

GPT-5.5 Pro and Grok 4.3 provide solid, correct, and adequately cited summaries. They address every prompt requirement but lack the exhaustive detail, formatting polish, and rigorous depth found in Hyperspace and Claude. GLM-5.2 is decently structured but contains a factual inaccuracy regarding Foreign Private Issuers, misleadingly stating they "must comply" with the majority-independent rule rather than explaining their ability to rely on home-country practices.

Self-Evaluation: Fugu Ultra My own answer, Fugu Ultra, unfortunately falls into the bottom half of the pack. While it is highly readable and correctly addresses the general definition, the subjective/objective eligibility tests, and the various company exemptions, it suffers from two major weaknesses relative to the winner. First, it completely lacks grounding; whereas Hyperspace and the others provide verifiable links or citations to the NASDAQ 5600 series and external legal analyses, my response provides zero sources. Second, my answer lacks the strict completeness of the top models: it entirely omits the specific "interested person" disqualification standard for investment companies under Rule 5605(a)(2)(G). By failing to provide citations and missing a material bright-line disqualification rule, my answer loses decisively on both depth and grounding.

GLM-5.2 — self-evaluation

Best answer: Claude Fable 5

Claude Fable 5 provides the most comprehensive, accurate, and directly responsive answer. It correctly defines independent directors under Rule 5605(a)(2), explicitly detailing both the subjective board determination and objective bright-line tests. Its eligibility and disqualification criteria are exhaustive, accurately capturing the $120,000 and $200,000/5% thresholds, the three-year look-backs, and the specific exceptions. Crucially, it thoroughly addresses which companies require independent directors, detailing not only the general majority-independent board requirement but also committee mandates (audit, compensation, nominations) and comprehensively listing all relevant exemptions (controlled companies, FPIs, limited partnerships, asset-backed issuers, etc.) with precise phase-in rules. It also correctly notes the recent vacatur of the board diversity rule, demonstrating up-to-date grounding.

My answer (Hyperspace) is highly accurate and well-structured, but it falls short of the winner in a few specific areas. While I correctly identified the disqualification thresholds and exemptions, my coverage of the specific phase-in periods for newly listed companies was slightly less precise than Claude Fable 5's explicit timelines (e.g., 90 days for audit committee majority). Additionally, while I mentioned smaller reporting companies in the general rules, I lacked a dedicated breakdown of their specific compensation committee accommodations, which the winner included.

Other systems, such as GPT-5.5 Pro and Fugu Ultra, provided strong summaries but lacked the depth of Claude Fable 5's committee requirements and phase-in schedules. Grok 4.3 omitted the Investment Company Act disqualifier (G), and GLM-5.2 inaccurately stated that Foreign Private Issuers must comply with the majority-independent board requirement, missing the home-country practice exemption. Overall, Claude Fable 5 is the definitive, most grounded, and responsive answer.

Mistral Large 3 — independent judge

Best answer: Hyperspace

Hyperspace stands out as the best answer due to its comprehensive depth, precise grounding in NASDAQ rules, and meticulous responsiveness to every facet of the question. Below is a comparative evaluation of its strengths and the notable gaps in the other answers.

Why Hyperspace Wins

  1. Correctness & Depth

    • Hyperspace is the only answer that explicitly distinguishes between the subjective board determination and the objective bright-line tests (A–G) with clarity, including the three-year look-back nuances and exceptions (e.g., retirement plans, charitable programs). It even provides a worked example to illustrate the look-back period—a critical detail missing elsewhere.
    • It correctly identifies the heightened standards for audit/compensation committees (Rule 10A-3, NASDAQ’s additional financial-sophistication requirement) and explains how they interact with the general independence standard. Other answers either omit this or conflate the two.
  2. Grounding/Citations

    • Hyperspace cites primary sources (Nasdaq Rule 5605, SEC Rule 10A-3, IM-5605) with pinpoint accuracy, including practitioner guides (Weil, Cooley, Skadden) that contextualize the rules. The citations are hyperlinked and dated, ensuring verifiability.
    • It explicitly flags the Investment Company Act’s "interested person" test (Rule 5605(a)(2)(G)) as a replacement for (A)–(F) for funds—a detail omitted by Claude and Grok.
  3. Responsiveness

    • The answer directly addresses every sub-question:
      • Definition: Quotes Rule 5605(a)(2) verbatim and explains its dual-layer structure.
      • Eligibility: Breaks down the subjective/objective tests with bullet points.
      • Disqualification: Uses a table to map each bright-line test (A–G) to thresholds, look-backs, and exceptions (e.g., "$120k vs. $200k/5%").
      • Required companies: Lists exemptions (controlled companies, FPIs, etc.) with granularity, including phase-ins for IPOs and bankruptcy exits.
    • It anticipates practical questions (e.g., "What if a director left 2 years ago?") with a worked example, while others merely restate the rules.
  4. Structure & Clarity

    • The logical flow (definition → eligibility → disqualification → required companies → exemptions) mirrors the question’s structure. The use of bold headers, tables, and bullet points makes complex rules digestible.

1. Claude Fable 5 (Strong Contender)

Strengths:

  • Nearly matches Hyperspace in correctness and covers all sub-questions, including the audit/compensation committee nuances.
  • Cites primary sources (Nasdaq rules, SEC Rule 10A-3) and practitioner blogs.
  • Explicitly notes the "interested person" test for funds (Rule 5605(a)(2)(G)).

Weaknesses vs. Hyperspace:

  • Less granular on exceptions: Omits details like the non-discretionary charitable matching program exception in Rule 5605(a)(2)(D) or the two-year audit committee exception.
  • No worked example: Fails to illustrate the three-year look-back, leaving ambiguity.
  • Citations are less precise: Uses generic links (e.g., "SecuritiesLawyer101") rather than pinpointing rule sections like Hyperspace.

2. Grok 4.3 (Solid but Incomplete)

Strengths:

  • Accurately quotes Rule 5605(a)(2) and lists disqualification criteria (A–F) with correct thresholds.
  • Exemptions section is well-organized, covering controlled companies, FPIs, and IPO phase-ins.

Weaknesses vs. Hyperspace:

  • Omits Rule 5605(a)(2)(G) (investment companies) entirely.
  • No table for disqualification criteria: Buries exceptions in prose, making it harder to parse.
  • Lacks depth on audit/compensation committees: Doesn’t explain the financial-sophistication requirement or SEC Rule 10A-3’s compensatory-fee prohibition.

3. GPT-5.5 Pro (Correct but Superficial)

Strengths:

  • Gets the basics right: Definition, eligibility, and disqualification criteria are accurate.
  • Includes a table for disqualification criteria (though less detailed than Hyperspace’s).

Weaknesses vs. Hyperspace:

  • No discussion of audit/compensation committee standards (e.g., Rule 10A-3, financial sophistication).
  • Exemptions are oversimplified: Doesn’t distinguish between controlled companies’ audit committee obligations vs. other exemptions.
  • No citations beyond Nasdaq’s rulebook: Lacks practitioner context or SEC sources.

4. Fugu Ultra (Accurate but Disorganized)

Strengths:

  • Correctly lists disqualification criteria (A–G) and exemptions.
  • Explicitly mentions the "interested person" test for funds.

Weaknesses vs. Hyperspace:

  • Poor structure: Mixes eligibility, disqualification, and exemptions without clear headers.
  • No table: Disqualification criteria are buried in prose.
  • Omits critical details: Doesn’t explain the three-year look-back exceptions (e.g., retirement plans) or the audit committee’s heightened standards.

5. GLM-5.2 (Minimalist)

Strengths:

  • Quotes Rule 5605(a)(2) accurately and lists disqualification criteria.

Weaknesses vs. Hyperspace:

  • No depth: Disqualification criteria are listed without thresholds, look-backs, or exceptions.
  • Exemptions are incomplete: Doesn’t mention FPIs, IPO phase-ins, or the audit committee’s financial-sophistication requirement.
  • No citations beyond Nasdaq’s rulebook: Lacks grounding in SEC rules or practitioner sources.

Key Takeaways

  • Hyperspace is the gold standard for its precision, depth, and practical guidance. It’s the only answer that would serve as a standalone reference for a compliance officer or attorney.
  • Claude Fable 5 is a close second but loses points for omitting practical examples and less granular exceptions.
  • Grok 4.3 and GPT-5.5 Pro are correct but lack the nuance and structure needed for full responsiveness.
  • Fugu Ultra and GLM-5.2 are too superficial to be relied upon for detailed compliance work.
