What Is PTE 77-4 for a 401(k) Plan?

PTE 77-4 addresses a conflict that appears when the same financial organization can both decide where a 401(k) invests and earn advisory fees from the mutual fund receiving those assets. The exemption can permit that affiliated-fund investment, but it is built around a narrow product scope, limits on transaction and advisory fees, and written approval by a second fiduciary that is independent of the firm benefiting from the fund.^[1][2]

The practical mistake is treating PTE 77-4 as a proprietary-fund safe harbor.

It is not.

A fiduciary can satisfy the exemption and still make a poor investment decision. The fund can still be too expensive, redundant, underperforming, operationally weak or inferior to reasonable alternatives. PTE 77-4 solves a prohibited-transaction problem. ERISA's ordinary prudence and loyalty duties remain separate.^[3][4][12]

What Conflict Does PTE 77-4 Address?

Assume an investment manager manages a 401(k) plan.

The manager's affiliate also advises a mutual fund.

The manager directs:

$20 million

of plan assets into that fund.

The fund pays the affiliate an annual advisory fee of:

0.30%.

The affiliated organization now earns about:

$60,000 per year

from the plan's investment through the fund-level advisory fee.

The fiduciary's investment decision changes its own organization's revenue.

That is the conflict.

The issue is not automatically that the fund is bad. The fund may be excellent.

The issue is that the fiduciary is not economically neutral between:

• an unaffiliated fund that pays it nothing
• an affiliated fund that creates revenue for the fiduciary organization.

ERISA Section 406 restricts specified transactions and fiduciary self-interest. PTE 77-4 provides conditional relief for this particular affiliated open-end-fund structure.^[1][11]

PTE 77-4 Is Narrower Than “Proprietary Investment”

The operative prospective exemption covers the purchase or sale by an employee benefit plan of shares of an:

open-end investment company registered under the Investment Company Act of 1940

when the fund's investment adviser is also:

• a fiduciary to the plan, or
• an affiliate of that fiduciary,

and the investment adviser is not the employer of employees covered by the plan.^[1][3][4]

That product definition matters.

A proprietary:

• collective investment trust
• separately managed account
• private fund
• bank deposit product
• insurance separate account

is not transformed into a PTE 77-4 transaction merely because the same organization manages both the plan relationship and the investment.

The exemption is tied to registered open-end investment companies.

A Mutual Fund Can Be Affiliated Without Being Automatically Prohibited

Affiliation is what creates the need for analysis.

It does not automatically disqualify the fund.

The policy logic behind PTE 77-4 is practical. Financial institutions often operate multiple businesses:

• trust
• investment management
• registered investment adviser
• mutual fund adviser
• custody
• administration.

A rigid rule barring every plan from every affiliated fund could eliminate investments that are otherwise sensible.

PTE 77-4 therefore permits the transaction if the conflict is controlled through specific economic and governance conditions.^[1]

The conditions matter more than the label:

“proprietary fund.”

Condition One: The Plan Does Not Pay a Sales Commission

Section II(a) says the plan cannot pay a sales commission in connection with the covered purchase or sale.^[1]

That eliminates an obvious way the fiduciary organization could increase revenue simply by moving plan assets into or out of its own mutual fund.

Suppose the plan buys:

$5 million

of affiliated mutual fund shares.

A front-end sales load of:

3%

would equal:

$150,000.

If that charge were part of the covered transaction, the economics would become much harder to reconcile with the exemption's no-sales-commission condition.

PTE 77-4 was designed to remove that acquisition-and-sale incentive.

“Sales Commission” Is Not Identical to Every Brokerage Charge

Exchange-traded open-end funds created a question the 1977 exemption did not contemplate in modern form.

An ETF can be legally organized as a registered open-end investment company while its individual shares trade on an exchange.

DOL addressed that issue in Advisory Opinion 2002-05A.^[5]

Under the facts presented, DOL concluded that the PTE 77-4 term:

sales commission

did not include an ordinary brokerage commission paid for exchange trading when the executing broker was unaffiliated with:

• the fund
• its principal underwriter
• its investment adviser
• their affiliates.^[5]

That is a useful distinction.

The exemption does not say:

“No transaction cost can ever exist.”

It says the plan cannot pay the sales commission prohibited by the exemption.

Example: Exchange-Traded Open-End Fund

Plan fiduciary is affiliated with ETF adviser.

Plan buys ETF shares through:

Broker X.

Broker X is independent of:

• fund
• adviser
• principal underwriter
• fiduciary organization.

Broker X charges:

$1,500

for executing the exchange purchase.

Under the structure addressed by Advisory Opinion 2002-05A, that independent brokerage commission is not automatically treated as the PTE 77-4 sales commission.^[5]

The rest of PTE 77-4 still has to work.

One advisory opinion about transaction capacity does not erase:

• fee rules
• second-fiduciary approval
• prospectus disclosure
• prudence.

Condition Two: Redemption Fees Are Restricted

PTE 77-4 does not impose an absolute prohibition on every redemption fee.

A redemption fee can fit the exemption only if:

1. it is paid only to the investment company, and
2. its existence is disclosed in the fund prospectus in effect when the plan buys the shares and again in the prospectus in effect when the plan sells them.^[1]

The design matters.

A fee retained by the fund can serve a different purpose from compensation paid to the fiduciary organization.

For example, a redemption fee may be structured to protect remaining fund shareholders from transaction costs created by short-term trading.

That does not make every redemption fee reasonable.

It explains why the exemption treats:

fee retained by the fund

differently from:

fee paid to the conflicted fiduciary.

The Most Important Fee Rule: No Double Advisory Compensation

The core economics of PTE 77-4 appear in Section II(c).^[3][4]

The plan cannot pay an investment management, investment advisory or similar fee on assets invested in the affiliated mutual fund for the entire investment period in a way that results in impermissible duplicate advisory compensation.

DOL has repeatedly described the purpose as preventing a:

double investment advisory fee.^[3][4]

That means the same plan assets should not support:

• full direct plan-level advisory compensation to the fiduciary
• plus the fiduciary organization's fund-level investment advisory fee

without the fee treatment required by the exemption.

Two Common PTE 77-4 Fee Structures

The exemption provides two practical structures that appear repeatedly in DOL guidance.

Structure A: waive the plan-level advisory fee

Assets invested in the affiliated fund are excluded from the direct advisory-fee base.

Example:

Total plan assets:

$100 million

Affiliated mutual fund investment:

$20 million

Plan-level advisory fee:

0.40%.

Instead of charging 0.40% on the full $100 million, the manager charges the direct advisory fee on:

$80 million.

The affiliated fund separately pays its ordinary fund advisory fee under its Investment Company Act advisory agreement.

The plan does not pay the direct manager another investment advisory fee on the same $20 million.^[3][4]

Structure B: charge the plan-level fee but credit the fund advisory fee

Assume:

Plan-level advisory fee:

0.50%.

Fund-level advisory fee attributable to the plan's investment:

0.30%.

If the plan pays the 0.50% plan-level fee on all assets, the arrangement can use a credit representing the plan's pro-rata share of the advisory fee paid by the mutual fund.^[3][4]

Effective direct plan-level fee on those assets after the 0.30% credit:

0.20%.

The point is not that 0.20% is automatically reasonable.

The point is that the plan has not paid the same fiduciary organization the full 0.50% direct fee plus another 0.30% through the fund for the same advisory function.

The Credit Has to Match the Actual Advisory Economics

A nominal credit is not enough.

Suppose the plan invests:

$10 million

in the affiliated fund.

The plan's pro-rata share of the fund advisory fee equals:

$30,000.

A credit of:

$5,000

would not represent the plan's pro-rata share merely because the agreement calls it a:

“PTE credit.”

The calculation has to reflect the fee economics described by the exemption.

Useful controls include:

• fund advisory-fee rate
• plan ownership of fund shares
• applicable breakpoints
• fee waivers
• expense reimbursements
• changes during the period
• timing of credit application.

A compliance label cannot fix bad arithmetic.

Secondary Service Fees Are Different—but Only If the Services Really Are Different

Mutual fund affiliates can provide services beyond investment advice.

Examples include:

• transfer agency
• custody
• fund accounting
• shareholder administration
• tax recordkeeping.

DOL Advisory Opinions 1993-12A and 1993-13A addressed whether compensation for genuine secondary services must automatically receive the same credit treatment as investment advisory fees.^[3][4]

DOL concluded that PTE 77-4 does not automatically require crediting every non-advisory service fee paid by the fund to the fiduciary organization.

That statement has an important limitation:

the service must actually be non-advisory.^[3][4]

Service Labels Do Not Control

Assume an affiliate receives:

• 0.30% labeled “investment advisory fee”
• 0.08% labeled “administrative fee.”

If the 0.08% truly compensates the affiliate for:

• transfer agency
• accounting
• recordkeeping

it may be analytically different from the fund advisory fee.

If the 0.08% pays for:

• portfolio construction
• manager selection
• securities selection
• asset allocation

calling it:

administration

will not make it non-advisory.

DOL emphasized that classification depends on facts and circumstances.^[3][4]

Secondary Fees Still Matter to Prudence

Even where a secondary-service fee is not subject to the PTE's advisory-fee credit requirement, the plan fiduciary cannot ignore it.

DOL has emphasized review of the:

totality of fees

paid directly by the plan and indirectly through the mutual fund.^[3][4]

That creates two separate questions:

PTE question

Does the transaction satisfy the exemption's specific compensation conditions?

Fiduciary question

Are total direct and indirect fees prudent and reasonable for the services and investment received?

Passing the first does not answer the second.

12b-1 Fees Create a Harder Problem

Rule 12b-1 distribution fees did not exist in their modern form when PTE 77-4 was granted.

DOL addressed that gap in the 1993 opinions and later guidance.^[3][6]

The Department said it could not conclude PTE 77-4 would be available where a 12b-1 fee attributable to the plan's investment is paid to:

• the plan fiduciary, or
• an affiliate of the fiduciary.^[3]

The reasoning is economic.

A distribution fee paid from fund assets to the fiduciary organization can resemble a commission generated by the plan's investment.

Routing the payment through the fund does not necessarily neutralize the conflict.

Example: 12b-1 Fee to Fiduciary Affiliate

Plan invests:

$8 million

in affiliated mutual fund.

Fund pays:

0.25% 12b-1 fee

to an affiliate of the plan fiduciary.

Revenue attributable to the plan investment:

$20,000 per year.

The fee is not shown as a separate line-item debit from the plan account.

Economically, the plan investment still generates compensation for the fiduciary organization.

DOL's published guidance says that fact can prevent reliance on PTE 77-4 for the purchases and sales at issue.^[3][6]

That deserves separate analysis before assuming the ordinary fee-credit structure solves everything.

Unrelated Distribution Compensation Can Produce a Different Analysis

DOL has also distinguished situations where fund distribution compensation is paid to an unrelated party rather than the fiduciary organization.

Advisory Opinion 2006-06A arose under PTE 77-3, not PTE 77-4, but it reinforces the importance of tracing:

who actually receives the money.^[6]

A fee paid to:

• fiduciary
• fiduciary affiliate

creates different conflict economics from compensation paid entirely to an unrelated broker that does not share it with the fiduciary organization.

“12b-1 fee” is not a complete conflicts analysis.

Follow the revenue.

The Independent Second Fiduciary Is the Main Governance Control

PTE 77-4 does not allow the benefiting adviser simply to disclose the conflict to itself and proceed.

Section II(d) requires a second fiduciary that is:

• independent of the fiduciary/investment adviser
• unrelated to the fiduciary/investment adviser and its affiliates.^[4][7]

This fiduciary is the exemption's decision maker for the conflict-control process.

If the person approving the arrangement is economically dependent on the adviser, employed by its affiliate or otherwise unable to exercise independent judgment, the structure deserves scrutiny regardless of the title printed beneath the signature line.

The Second Fiduciary Needs More Than a Prospectus

PTE 77-4 requires the independent fiduciary to receive a current fund prospectus and full written disclosure addressing the affiliated fee relationship.^[4][7]

The disclosure includes information about:

• investment advisory fees
• other fees charged to or paid by the plan and fund
• differences between fee rates
• reasons the fiduciary/adviser considers the purchase appropriate
• limitations on which plan assets may be invested in fund shares.^[4]

The prospectus describes the fund.

The separate disclosure explains the conflict.

Those are not the same document.

“The Fund Is in the Prospectus” Is Not Enough

A fund prospectus can describe:

• objectives
• strategies
• risks
• expenses
• performance
• portfolio management.

It may not explain the full economics of the plan's relationship with the affiliated adviser.

For PTE 77-4, the second fiduciary needs to understand questions such as:

• What does the plan pay the manager directly?
• What does the fund pay the affiliate?
• Which fees are credited?
• Which fees are retained?
• Are there affiliated secondary-service fees?
• Is any distribution compensation paid to the fiduciary organization?
• Why is the affiliated fund being proposed?
• Is the manager restricted to its own funds?

The exemption is built around that conflict-specific information.^[4]

A Summary Prospectus Can Satisfy the Prospectus Condition

DOL updated its interpretation as SEC disclosure practice evolved.

In Advisory Opinion 2013-04A, DOL concluded that delivery of a qualifying SEC summary prospectus can satisfy PTE 77-4's prospectus-distribution requirement for that purpose.^[7]

That conclusion reflects the SEC framework under which the summary prospectus provides key fund information and the statutory prospectus remains available through specified channels.

This is useful operationally.

A compliance process does not need to insist on a paper statutory prospectus if current SEC and DOL requirements permit the qualifying summary prospectus route.

The conflict-specific written fee disclosures still remain.

Approval Can Be Structured Three Ways

PTE 77-4 gives the independent second fiduciary flexibility in how written approval is documented.^[4]

Approval can be:

1. set out in the plan documents or investment management agreement
2. provided in writing before each purchase or sale
3. provided in writing before a specified program of purchases or sales begins.^[4]

That third route matters operationally.

A plan using an affiliated fund does not necessarily need a fresh committee signature before every contribution, rebalance or routine transaction.

Program Approval Can Cover Later Trades

DOL Advisory Opinion 1993-13A specifically concluded that PTE 77-4 can provide relief for later purchases and sales under a previously approved program without separate advance approval of every transaction, assuming the other conditions remain satisfied.^[4]

Example:

Investment committee approves a written program permitting the manager to allocate:

0% to 25%

of a portfolio mandate to specified affiliated funds, subject to documented strategy and fee conditions.

The manager later buys and sells fund shares within the approved program.

A new signature before every trade is not automatically required solely because a transaction occurred.^[4]

The program approval needs to be real.

An authorization that says:

“Manager may use any current or future affiliated product on any terms”

without meaningful fee or investment parameters may create a much weaker fiduciary record.

Program Approval Does Not Freeze the Arrangement Forever

The exemption contains a specific fee-change rule.

The independent fiduciary, or its successor, must be notified of changes in the relevant fee rates and approve in writing:

• continuation of purchases or sales, and
• continued holding of shares acquired before the fee change and still held by the plan.^[4]

The second point is often missed.

A fee change does not only affect:

the next purchase.

It can require a decision about:

the existing position.

Example: Existing Fund Raises Its Advisory Fee

Plan holds:

$15 million

in affiliated mutual fund.

Fund advisory fee increases from:

0.25%

to:

0.32%.

Annual fund-level advisory cost attributable to the plan rises from about:

$37,500

to:

$48,000.

Difference:

$10,500 per year.

The issue is not solved by saying:

“The fund was approved three years ago.”

The relevant second fiduciary needs the fee-change notice and written approval required by the exemption for continued activity and holding.^[4]

The fiduciary should also ask whether the fund remains worth the higher price under ordinary Section 404 analysis.^[12]

Fee Reapproval Is More Than a Compliance Signature

A meaningful review should ask:

• What changed?
• Why did the fund raise the fee?
• Did services change?
• Did peer pricing change?
• Does the plan-level fee credit change proportionally?
• Does the fund remain competitive after the increase?
• Would an unaffiliated substitute provide similar exposure at lower total cost?
• Has the affiliated-fund allocation grown materially since initial approval?

The exemption requires approval.

Fiduciary prudence determines whether the approval is defensible.

PTE Approval Can Be Limited to the Fee Relationship

PTE 77-4 says the second fiduciary's approval may be limited to the relationship between:

• fees paid by the mutual fund, and
• fees paid by the plan.^[4]

That provision can be misunderstood.

It does not mean nobody has to determine whether the fund is prudent.

It means the PTE's independent approval condition can be structured around the conflict the exemption is designed to address.

The plan still needs a fiduciary process for:

• investment merits
• diversification
• risk
• performance
• fees
• alternatives
• monitoring.^[12]

Different duties can sit with different fiduciaries.

They cannot disappear.

PTE 77-4 Does Not Replace Section 408(b)(2) Service-Provider Analysis

A plan's arrangement with an investment adviser, recordkeeper, trustee or other covered service provider can also involve separate ERISA service-provider disclosure and reasonable-compensation rules.

PTE 77-4 answers a more specific transaction question:

Can the fiduciary cause the plan to buy or sell shares of an affiliated advised open-end fund despite the conflict?

A 408(b)(2) analysis asks different questions about:

• services
• direct compensation
• indirect compensation
• fiduciary or RIA status
• related-party payments
• reasonableness of the arrangement.

One disclosure regime should not be treated as a substitute for the other.

Proprietary Fund Menus Create a Broader Fiduciary Question

Suppose a 401(k) menu contains:

18 investment options.

Fourteen are managed by the recordkeeper's investment affiliate.

PTE 77-4 may provide a route for the affiliated mutual fund transactions if its conditions are met.

That does not answer:

Why are 14 of 18 options proprietary?

The committee still needs evidence supporting:

• investment quality
• cost
• diversification
• share class
• performance
• participant utility
• availability of alternatives.

An exemption can legalize a conflicted transaction structure.

It cannot supply the investment rationale that the fiduciary record lacks.

The Better Benchmark Is Not “Cheaper Than Retail”

A proprietary fund family may argue that the plan receives:

• institutional share class
• no sales load
• favorable expense ratio.

Those facts can be useful.

The stronger comparison is against:

reasonable alternatives available to a plan of similar size and structure.

A 0.45% affiliated fund can be cheaper than the retail 0.90% share class and still be expensive relative to a 0.08% institutional alternative with comparable exposure.

PTE 77-4 does not make the retail share class the benchmark.

PTE 77-4 Is Not the Same as PTE 77-3

The numbers are close.

The exemptions solve different problems.^[2][6]

PTE 77-4

Addresses plan purchases and sales of registered open-end fund shares when the fund adviser is also a fiduciary to the plan or an affiliate, subject to the exemption's conditions.^[1][2]

PTE 77-3

Addresses specified plans covering employees of:

• the investment company
• its investment adviser
• principal underwriter
• affiliated persons of the adviser or underwriter.^[2][6]

That is an:

in-house plan

problem.

A financial institution analyzing its own employees' plan should not assume ordinary PTE 77-4 is the correct route simply because its investment affiliate manages the fund.

PTE 77-4 vs. PTE 77-3

The right exemption follows the actual relationship.

Not the fact that both transactions involve mutual funds.

PTE 77-4 Does Not Cover a CIT Merely Because It Looks Like a Mutual Fund

Collective investment trusts can look similar to mutual funds from a participant's perspective:

• daily valuation
• pooled assets
• target-date strategies
• institutional pricing.

Legally, the vehicles are different.

PTE 77-4 expressly addresses registered open-end investment companies.^[1]

A CIT generally relies on a different regulatory and ERISA structure.

If a plan fiduciary directs assets into an affiliated CIT, analyze:

• the trust structure
• fiduciary relationships
• party-in-interest status
• compensation
• applicable statutory or class exemptions
• plan-asset rules

instead of forcing the transaction into PTE 77-4.

Separate Accounts Need Their Own Conflict Analysis Too

A plan can hire an affiliated investment manager to manage a dedicated separate account.

No mutual fund shares may exist.

The account can still involve:

• investment management fees
• affiliated brokerage
• securities lending
• principal trades
• cross-trades
• custody
• indirect compensation.

Those issues can trigger other articles in this sequence:

• INV-146 for separate accounts
• INV-149 for securities lending
• INV-152 for cross-trading
• INV-153 for principal transactions
• INV-154 for agency brokerage.

PTE 77-4 should not become the default citation for every affiliated investment relationship.

Affiliated Mutual Fund vs. CIT vs. Separate Account

Product wrapper changes the exemption map.

The 2016 PTE 77-4 Amendment Is Not the Operating Rule

DOL amended PTE 77-4 in 2016 as part of the prior fiduciary-rule package.

The Fifth Circuit vacated that rulemaking and associated exemptions.

In 2020, DOL published a notice restoring the affected exemptions to their pre-amendment form.^[9]

That history matters because compliance manuals written between:

2016 and 2018

can contain language that is no longer operative.

The 2024 Amendment Was Vacated Too

DOL again amended PTE 77-4 in 2024 alongside the Retirement Security Rule.

The 2024 package would have removed fiduciary investment-advice transactions from several older administrative exemptions, including PTE 77-4.^[8]

Federal courts vacated the rule and associated PTE amendments.

DOL's current Retirement Security page acknowledges the vacatur and lists PTE 77-4 among the affected amendments.^[8]

The 2024 amendment text therefore should not be treated as the operative 2026 PTE 77-4 framework.

The Practical 2026 Baseline Is the Pre-2016 PTE 77-4 Framework

For current analysis, use the pre-2016/original PTE 77-4 structure reflected in DOL's current exemption materials and longstanding advisory opinions, rather than the vacated 2016 or 2024 amendment packages.^[1][2][8][9]

That means the familiar condition set remains central:

• registered open-end fund
• no prohibited plan-paid sales commission
• limited redemption-fee route
• no duplicate advisory compensation
• independent second fiduciary
• prospectus and detailed fee disclosure
• written approval
• fee-change notice and written continuation approval.

The Information Collection Was Renewed in July 2026

PTE 77-4's disclosure and approval mechanics are not merely historical language sitting in an old Federal Register document.

OIRA approved DOL's current information collection for PTE 77-4 on:

July 29, 2026.^[10]

OMB Control Number:

1210-0049

is active through:

July 31, 2029.^[2][10]

That current renewal is strong evidence that DOL continues to administer the exemption's disclosure framework.

The OMB expiration date concerns the information collection approval.

It is not an automatic expiration date for PTE 77-4 itself.

A PTE 77-4 File Should Reconcile Three Layers of Compensation

A clean review should separate:

1. Plan-level compensation

Examples:

• investment management fee
• advisory fee
• trustee fee
• recordkeeping fee
• managed-account fee.

2. Fund-level affiliated compensation

Examples:

• investment advisory fee
• subadvisory fee
• transfer agency
• custody
• administration
• shareholder servicing
• distribution compensation.

3. Transaction compensation

Examples:

• sales commission
• redemption fee
• exchange brokerage commission.

The exemption treats these categories differently.

A spreadsheet with one line labeled:

“Fund expense ratio: 0.42%”

usually does not show enough.

Example: Full Compensation Map

Plan assets:

$250 million.

Affiliated fund allocation:

$50 million.

Direct plan advisory fee:

0.35%.

Fund advisory fee:

0.20%.

Affiliated fund administration fee:

0.04%.

Unaffiliated custody inside fund:

0.02%.

No 12b-1 fee.

No sales load.

If the plan-level fee is charged on the full $250 million, the PTE process should identify the pro-rata advisory-fee credit required for the affiliated fund allocation.^[3][4]

The 0.04% administration fee requires a separate question:

Is it genuinely compensation for a non-advisory service?

The 0.02% unaffiliated custody expense still matters to total fund cost even though it does not create the same affiliated compensation conflict.

That is the level of disaggregation a serious review needs.

The Independent Fiduciary Should See the Fee Bridge

A useful disclosure does not force the second fiduciary to reconstruct the economics from five documents.

It can present a simple bridge:

That table will often reveal more than a forty-page contract.

Proprietary Funds Can Create Revenue Concentration

A plan may satisfy the mechanics of PTE 77-4 while the provider's revenue becomes heavily dependent on affiliated investments.

Example:

Provider receives from plan:

$300,000

in direct annual fees after credits.

Provider affiliates receive another:

$900,000

through proprietary fund advisory and service fees attributable to plan assets.

The committee should understand that concentration.

Questions include:

• Is the menu designed around participant needs or provider economics?
• Are affiliated funds winning because of documented merit?
• Are unaffiliated alternatives evaluated on equal terms?
• Do fund replacements reduce provider revenue and therefore create resistance?

PTE compliance does not answer those governance questions.

A Zero Direct Advisory Fee Does Not Mean the Relationship Is Free

Some arrangements waive all plan-level investment advisory fees on proprietary fund assets.

That can satisfy the no-double-advisory-fee structure.

It can also obscure the economics.

If the affiliated fund charges:

0.65%

and a comparable unaffiliated institutional fund costs:

0.10%,

the waived direct fee is not the end of the analysis.

The participant can still bear the higher fund expense through reduced investment returns.

“Fee waived” can be technically accurate and economically incomplete.

A Low-Cost Proprietary Fund Can Still Be a Bad Choice

Reverse the facts.

Affiliated index fund costs:

0.03%.

Unaffiliated alternatives cost:

0.05% to 0.08%.

The affiliated fund tracks poorly, has operational problems and repeatedly misses its benchmark by more than peers after accounting for its stated fee.

Low expense ratio does not rescue weak implementation.

The committee should monitor:

• tracking difference
• tracking error
• securities lending economics
• portfolio turnover
• cash drag
• execution
• benchmark fit
• operational incidents.

PTE 77-4 is a conflict exemption.

It is not an expense-ratio contest.

Exempt Transaction vs. Prudent Fund Selection

Do not collapse these into one vote.

What Should Be Reviewed Before Initial Approval?

Product scope

• Is the investment a registered open-end investment company?
• Is the proposed share class covered by the actual fund structure?
• Is an ETF legally organized as an open-end fund if relying on the ETF guidance?

Relationship map

• Who is the plan fiduciary?
• Who advises the fund?
• Are they the same entity or affiliates?
• Is the fund adviser the employer of employees covered by the plan?
• Which affiliates receive compensation?

Transaction charges

• Any sales load?
• Any redemption fee?
• Who receives it?
• Is it properly disclosed?
• Any exchange brokerage commission?
• Is the broker affiliated?

Advisory compensation

• Direct plan advisory fee?
• Fund-level advisory fee?
• Fee waiver or pro-rata credit?
• Calculation methodology?
• Timing?

Other affiliated revenue

• transfer agency
• administration
• custody
• subadvisory
• shareholder servicing
• 12b-1 or distribution compensation
• other indirect compensation.

Independent approval

• Who is the second fiduciary?
• Is independence real?
• Has the fiduciary received the current prospectus or qualifying summary prospectus?
• Has it received the required detailed fee disclosure?
• Are reasons for the investment and investment limitations disclosed?
• Is approval transaction-specific, document-based or program-based?

Investment merits

• objective
• benchmark
• performance
• risk
• expense ratio
• share class
• alternatives
• role in menu or portfolio.

The PTE file should show both:

why the exemption applies

and:

why the fund belongs in the plan.

What Should Ongoing Monitoring Test?

Fee credits

Recalculate rather than assuming the recordkeeper got them right.

Fund fee changes

Flag changes immediately because PTE 77-4 has a specific written reapproval consequence.^[4]

New affiliated compensation

A fund can add or change:

• administration
• shareholder servicing
• distribution
• subadvisory arrangements.

12b-1 status

Confirm whether any distribution fee exists and who receives it.

Share class

A cheaper eligible share class may become available as assets increase.

Proprietary concentration

Measure:

• percentage of menu affiliated
• percentage of plan assets affiliated
• percentage of provider compensation generated by affiliated funds where data are available.

Fund quality

Review:

• performance
• risk
• personnel
• process
• benchmark
• costs
• operational issues.

Second-fiduciary governance

Confirm:

• responsible person still independent
• disclosures are current
• approvals are documented
• fee changes did not bypass the process.

Frequently Asked Questions

What is PTE 77-4?

A Department of Labor class exemption that can permit an employee benefit plan to purchase or sell shares of a registered open-end investment company when the fund adviser is also a plan fiduciary or affiliate, subject to specified conditions.^[1][2]

Why would a 401(k) need it?

Because a fiduciary that can direct plan assets into a mutual fund advised by itself or an affiliate can create prohibited-transaction and self-interest concerns when the affiliated organization earns compensation from the fund.

Does PTE 77-4 allow any proprietary investment?

No. The exemption is tied to registered open-end investment companies and its specific relationship and condition structure.^[1]

Can a CIT rely on PTE 77-4?

Not merely because it is proprietary. A CIT is not ordinarily a registered open-end investment company, so another ERISA and exemption analysis is required.

Can the plan pay a sales load?

The prospective exemption requires that the plan not pay a sales commission in connection with the covered purchase or sale.^[1]

Are redemption fees always prohibited?

No. A redemption fee can fit only under the exemption's conditions, including payment solely to the fund and prospectus disclosure at purchase and sale.^[1]

What is the double-fee rule?

The plan cannot pay duplicative investment advisory or similar compensation on the same assets. Common structures use either a direct plan-level fee waiver for assets invested in the affiliated fund or a credit for the plan's pro-rata share of the fund-level advisory fee.^[3][4]

Must every fund-level service fee be credited?

Not automatically. DOL has distinguished genuine secondary services from investment advisory services, but classification depends on facts and circumstances, and relevant affiliated fees still must be disclosed and evaluated.^[3][4]

Are 12b-1 fees allowed?

DOL has said it was unable to conclude PTE 77-4 would be available when a 12b-1 fee attributable to the plan's investment is paid to the plan fiduciary or its affiliate.^[3]

Who approves the arrangement?

A second fiduciary that is independent of and unrelated to the fiduciary/investment adviser or its affiliates receives the required materials and provides the written approval contemplated by the exemption.^[4][7]

Does the independent fiduciary need the full statutory prospectus?

DOL Advisory Opinion 2013-04A concluded that a qualifying SEC summary prospectus can satisfy the PTE 77-4 prospectus-distribution requirement for that purpose.^[7]

Does every purchase require separate approval?

No. The exemption permits approval in plan documents or the management agreement, transaction-by-transaction written approval, or written approval of a specified purchase or sale program. DOL has confirmed that later trades under an approved program need not receive separate prior approval solely because each trade occurs.^[4]

What happens if the fund fee changes?

The relevant second fiduciary must be notified and provide written approval of continued purchases or sales and continued holding of previously acquired shares under the exemption's fee-change condition.^[4]

Can an ETF qualify?

An ETF organized as a registered open-end investment company can fall within the product scope. DOL has also concluded that an exchange brokerage commission paid to an unaffiliated broker under the facts of Advisory Opinion 2002-05A was not the prohibited sales commission.^[5]

Is PTE 77-4 the same as PTE 77-3?

No. PTE 77-3 addresses specified in-house plans covering employees of mutual fund complexes, advisers, principal underwriters or affiliates.^[2][6]

Are the 2024 PTE 77-4 amendments current?

No. DOL's current Retirement Security materials state that the 2024 rule and associated PTE amendments were vacated by court order.^[8]

What version applies in 2026?

The practical baseline is the pre-2016 PTE 77-4 framework reflected in the original exemption and DOL guidance. The 2016 amendment package was vacated and technically restored to pre-amendment form in 2020; the 2024 amendment package was also vacated.^[1][8][9]

Is PTE 77-4 still active administratively?

Yes. DOL currently lists PTE 1977-04 among its class exemptions, and OIRA approved the associated information collection under OMB Control No. 1210-0049 through July 31, 2029.^[2][10]

Does satisfying PTE 77-4 prove the proprietary fund is prudent?

No. ERISA Section 404 duties remain separate. The fiduciary still needs a prudent, loyal process for investment selection and monitoring and should evaluate total direct and indirect fees.^[3][4][12]

PTE 77-4 Review Test

Identify the registered open-end investment company → identify the fund's investment adviser → identify the plan fiduciary that can cause or influence the investment → map affiliation between the fiduciary and fund adviser → confirm the fund adviser is not the employer of employees covered by the plan for the ordinary PTE 77-4 route → identify any sales commission → identify any redemption fee and who receives it → map direct plan-level investment advisory compensation → map fund-level advisory compensation attributable to plan assets → apply a compliant plan-level fee waiver or pro-rata advisory-fee credit structure → identify every other affiliated fund-level fee → distinguish genuine secondary services from investment advisory services based on actual functions → identify any 12b-1 or distribution compensation and trace the recipient → identify an independent and unrelated second fiduciary → deliver the current prospectus or qualifying summary prospectus → provide detailed written affiliated-fee disclosure, fee differentials, reasons the fund is considered appropriate and any investment limitations → obtain written approval through the plan/agreement, transaction-specific approval or specified-program approval → document the scope of any program approval → establish an automated flag for relevant fee-rate changes → notify the second fiduciary of fee changes → obtain written approval for continued purchases/sales and continued holding after the change → for exchange-traded open-end funds, classify any brokerage commission and broker affiliation under current DOL guidance → confirm the product is not being incorrectly treated as PTE 77-4 when it is a CIT, separate account or other vehicle → test whether PTE 77-3 or another exemption is the correct route for an in-house plan or different relationship → evaluate total compensation, share class, alternatives and investment merits separately under Section 404 → use the operative pre-2016 PTE 77-4 framework rather than vacated 2016 or 2024 amendment language

The useful question is not:

“Are proprietary mutual funds allowed in a 401(k)?”

It is:

“Does this exact affiliated-fund transaction fit PTE 77-4, has an independent fiduciary been given enough information to approve the conflict, have duplicate advisory economics been eliminated, and can the plan still show that the fund itself deserves the assets?”

That separates exemption compliance from investment judgment.

Educational Disclaimer

ROIStreet publishes educational content about retirement-plan fiduciaries, mutual funds, investment-adviser conflicts and ERISA prohibited-transaction exemptions. This article is not legal, fiduciary, tax, securities, investment or plan-administration advice. PTE 77-4 is highly technical. Availability depends on the exact investment vehicle, adviser and fiduciary relationships, employer relationship, compensation flows, sales and redemption charges, fee-credit methodology, independent-fiduciary status, disclosures, approvals, fee changes and current law. An exempt affiliated-fund transaction can still violate ERISA's fiduciary duties if the investment, fees, share class, alternatives or monitoring process are imprudent.
