What Is PTE 90-1 for a 401(k) Plan?

PTE 90-1 is the prohibited-transaction exemption designed for insurance company pooled separate accounts. Its central idea is structural: when many retirement plans invest through one insurer-maintained pool, the pool can encounter parties in interest connected to one participating employer even though the transaction was selected for the portfolio as a whole. The exemption can permit many of those transactions without forcing the insurer to identify and avoid every indirect relationship—but only within defined concentration, counterparty, pricing and recordkeeping limits.^[1][2][3]

The most important current rule is usually:

10%.

For the general route, one sponsor group's combined plan investments generally cannot exceed 10% of the pooled account.^[2]

That percentage is easy to state.

Applying it correctly requires understanding what the pool actually is.

A Pooled Separate Account Is Not a Dedicated Separate Account

INV-146 explains why the phrase separate account is ambiguous.

A large 401(k) can hire an investment manager to manage a portfolio dedicated only to that plan.

That arrangement can be called a:

separate account

in institutional investment practice.

PTE 90-1 addresses a different structure:

a pooled account maintained by an insurer for multiple plan investors.

Multiple plans place assets into one insurer-maintained account and share economic exposure to its underlying investments.

The pooled nature is what creates both the efficiency and the exemption problem.

Why Does Pooling Create Indirect ERISA Conflicts?

Assume a pooled separate account has:

$1 billion

of assets from 40 retirement plans.

One participating employer is Corporation A.

The pooled account considers buying bonds issued by Bank B.

Bank B provides services to Corporation A's 401(k).

Bank B can therefore be a party in interest with respect to that plan.^[6]

The insurer is making one investment for a $1 billion pool.

Yet one participating plan's relationship with Bank B can cause ERISA Section 406 to reach the transaction.

Now multiply that problem by:

• dozens of plans
• hundreds of service providers
• employers
• affiliates
• lenders
• landlords
• issuers.

Without pooled-fund relief, ordinary institutional investing can become operationally difficult.

PTE 90-1 is designed for that problem.

Why Are the Underlying Assets Treated as Plan Assets?

The plan-asset regulation has a specific rule for insurance company separate accounts.

When a plan acquires an interest in a qualifying insurance-company separate account, the plan's assets generally include:

• its interest in the account
• an undivided interest in each underlying asset

unless the separate account is maintained solely in connection with fixed contractual obligations whose payments are not affected by the separate account's investment performance.^[5]

That underlying-asset treatment is why prohibited-transaction analysis reaches through the pooled vehicle.

The plan does not directly own the bond, building or loan in ordinary commercial form.

ERISA can still treat it as owning a fractional interest for fiduciary purposes.

PTE 90-1 Solves a Vehicle-Level Problem

The exemption does not depend on proving:

this investment manager is a QPAM.

It asks whether the transaction sits inside the defined insurance pooled-account framework.

That matters because there are several ways institutional plans can obtain party-in-interest relief.

A transaction might rely on:

• PTE 90-1 because assets sit in an insurance pooled separate account
• PTE 91-38 because assets sit in a bank collective investment fund
• PTE 84-14 because an independent QPAM made the decision
• PTE 95-60 because the assets are in an insurance company general account.^[1][10]

These are different legal routes.

The asset vehicle matters.

The Exemption Began as PTE 78-19

The original class exemption was issued as:

PTE 78-19.

In 1990, DOL amended it and redesignated the exemption:

PTE 90-1.^[2]

The 1990 amendments made three important changes:

1. increased the principal concentration limit from 5% to 10%
2. increased a separate real-property goods/lease threshold from 0.025% to 0.5%
3. added relief for specialized pooled accounts investing substantially all assets in short-term obligations.^[2]

Those changes explain much of the current structure.

The Basic Exemption Reaches More Than One ERISA Section

Section I states relief from specified restrictions under:

• ERISA Section 406(a)
• Section 406(b)(2)
• Section 407(a)

and corresponding Code prohibited-transaction taxes, subject to the exemption's conditions.^[2][6][9]

That matters because the relief is broad.

It can cover:

• direct or indirect sales
• exchanges
• leases
• loans or extensions of credit
• furnishing goods, services or facilities
• transfers or use of plan assets for a party in interest
• specified employer-security and employer-real-property issues
• certain adverse-party representation conflicts under Section 406(b)(2).

But the list also shows what is missing.

The Basic Route Is Not Blanket Self-Dealing Relief

Section I does not say:

all of Section 406(b).

The text expressly references Section 406(b)(2), not Sections 406(b)(1) and (3).^[2][6]

Those other provisions address problems such as:

Section 406(b)(1)

A fiduciary dealing with plan assets in its own interest or for its own account.

Section 406(b)(3)

A fiduciary receiving consideration for its own personal account from a party dealing with the plan in connection with a plan transaction.^[6]

A pooled account can satisfy the 10% test and still have a separate fiduciary self-dealing problem.

That distinction prevents overreliance on the exemption.

Example: Party-in-Interest Bond Purchase vs. Insurer Self-Dealing

Transaction A

Pooled account buys a bond from Company X.

Company X is a party in interest only because it has a relationship to one small participating plan.

The sponsor-group plan interest is below 10%.

The insurer is unrelated to Company X.

That is the type of indirect pooled-account conflict the general exemption can address.

Transaction B

The insurer uses pooled assets to buy property from itself at an advantageous price.

Now the insurer is on both sides.

The general Section I(a) route specifically excludes the insurance company holding the plan assets and its affiliates as covered counterparties.^[2]

The 10% test does not turn self-dealing into an ordinary transaction.

The General Route Excludes the Insurer and Its Affiliates

The basic exemption is available only if the party in interest is not:

• the insurance company that maintains the pool and holds the participating plan assets
• another separate account of that insurance company
• an affiliate of the insurance company.^[2]

This is a crucial limitation.

PTE 90-1 is often described as broad party-in-interest relief.

That is true for the diversified network of counterparties connected to participating plans.

It is not broad permission for the insurer to transact with itself.

Why Exclude Another Separate Account of the Same Insurer?

Imagine Insurer I manages:

• Pooled Account A
• Pooled Account B.

Account A sells an asset directly to Account B.

Both are managed inside the same insurance organization.

The insurer can influence:

• timing
• price
• allocation
• which account receives the more attractive economics.

The ordinary 10% pooled-account rule is not designed to resolve that internal allocation conflict.

Another exemption or legal route may be needed.

The Current General Concentration Limit Is 10%

For transactions on or after July 1, 1988, Section I(a)(1)(iii) uses:

10% of total pooled separate-account assets.^[2]

The numerator is:

the investing plan plus other plans sponsored by that employer or employee organization and invested in the same pool.

The denominator is:

the pooled vehicle's total assets.

That is a sponsor-group concentration measure.

It is not a plan-size test.

Example: One Plan at 9%

Pooled separate account:

$800 million.

Corporation A 401(k) investment:

$72 million.

$72 million ÷ $800 million = 9%.

If Corporation A maintains no other plan invested in the account, the ordinary concentration condition is within 10%.

That does not complete the exemption analysis.

The transaction still has to satisfy:

• counterparty restriction
• arm's-length pricing
• records
• any transaction-specific conditions.

But the concentration gate is open.

Two Related Plans Must Be Aggregated

Same pooled account:

$800 million.

Corporation A 401(k):

$60 million.

Corporation A pension plan:

$35 million.

Combined:

$95 million.

Percentage:

$95 million ÷ $800 million = 11.875%.

Looking only at the 401(k):

7.5%.

Looking at the employer's combined plans:

11.875%.

The ordinary 10% route fails that concentration test.

Dividing assets between plans does not reduce sponsor-group influence.

The Denominator Is the Pool, Not the Employer's Plan Assets

Suppose Corporation A has:

$4 billion

of retirement assets.

Only:

$90 million

is invested in a:

$600 million

pooled separate account.

The relevant percentage is:

$90 million ÷ $600 million = 15%.

It is not:

$90 million ÷ $4 billion = 2.25%.

The exemption measures the employer-group's footprint inside the investment pool.

That is the source of potential influence and concentrated relationship risk.

Why 10% Is a Structural Safeguard

At 1% of a large diversified pool, one employer's plan relationships are unlikely to define the economics of the whole account.

At 45%, the analysis changes.

The insurer knows nearly half the pool belongs to one sponsor group.

Transactions involving that employer or its counterparties can become less incidental.

The concentration limit does not prove independence.

It reduces the degree to which one sponsor group's relationships can dominate the pooled vehicle.

Crossing the Threshold Can Matter After Initial Investment

PTE 90-1 contains a timing rule addressing when the exemption applies to a transaction, acquisition or holding.^[2]

The text also states that Section I(a) relief can cease for a holding when the plan's interest exceeds the percentage limit if the excess results solely from an increase in consideration allocated to the pooled account by the plan.^[2]

That creates an operational issue:

contributions can matter.

A plan that starts at 8.5% cannot assume the exemption remains available indefinitely while it adds assets.

Example: Contributions Push the Plan Above 10%

Pooled account before contribution:

$500 million.

Employer group investment:

$45 million.

Share:

9%.

Employer contributes another:

$12 million

while the rest of the pool is unchanged.

New pool total:

$512 million.

Employer group total:

$57 million.

Share:

11.13%.

The insurer now needs to reassess reliance on Section I(a) for holdings and transactions affected by the concentration rule.

A quarterly compliance report is too late if the relevant transaction occurs in between.

Market Movements Are Different From New Allocations

The exemption's timing language is more nuanced than:

test 10% every day and sell immediately if market values move.

The rule focuses on transaction/acquisition timing and specifically identifies an excess caused solely by increased consideration allocated by the plan as a circumstance that can end relief for a holding.^[2]

That is why a compliance procedure should distinguish:

• new contribution
• redemption by other investors
• market appreciation
• transaction date
• valuation date.

The legal consequence can depend on how the percentage changed.

Each Plan Owns a Fractional Share of Every Pooled Asset

Section IV provides an attribution rule.

Each plan is treated as owning the same fractional share of each pooled-account asset as its fractional share of total pooled-account assets on the most recent preceding valuation date.^[2]

If a plan owns:

4%

of the pooled account, it is treated as owning:

4% of each underlying asset

for purposes of the exemption's framework.

That rule is essential for understanding:

• employer securities
• employer real property
• indirect holdings
• concentration.

A pooled vehicle does not erase plan-level attribution.

The Specialized Short-Term Account Is an Alternative Route

The 1990 amendment added a second path under Section I(a).^[2]

A pooled separate account can qualify as a:

specialized account

that has a policy of investing—and actually invests—substantially all of its assets in qualifying short-term obligations.

This route is not framed around the ordinary 10% sponsor-group percentage.

It solves a different practical problem.

Short-term liquidity pools frequently transact with:

• banks
• corporate issuers
• dealers
• counterparties

that may be parties in interest to one or more participating plans.

The Short-Term Obligation Must Mature Within One Year

The exemption describes short-term obligations as having:

• a stated maturity date of one year or less, or
• a maturity date one year or less from the specialized account's acquisition date.^[2]

That is a maturity test.

Not an expected-holding-period test.

A five-year note does not become short term because the manager intends to sell it next month.

The Exemption Gives Specific Short-Term Examples

The listed examples include:

• corporate obligations
• governmental obligations
• related repurchase agreements
• certificates of deposit
• bankers acceptances
• variable-amount notes of borrowers of prime credit.^[2]

The list is not necessarily exhaustive.

The governing concepts remain:

• specialized account policy
• substantially all assets
• short-term obligation
• one-year maturity framework.

The portfolio should be designed around the exemption.

Not reverse-engineered after a trade.

Example: Specialized Liquidity Pool

Insurance pooled account has:

$1.2 billion.

Portfolio:

• 35% Treasury and agency obligations under one year
• 25% high-quality commercial paper
• 20% certificates of deposit
• 10% bankers acceptances
• 8% qualifying repurchase agreements
• 2% operational cash.

The account's governing policy expressly limits investments to short-term instruments.

That resembles the specialized-account architecture.

A portfolio with:

• 60% five-year corporate bonds
• 20% equities
• 20% short-term instruments

does not become a specialized short-term account merely because its manager labels the 20% sleeve:

liquidity.

"Substantially All" Is Not a Number Stated in PTE 90-1

The exemption says:

substantially all.^[2]

It does not provide a neat:

90%

or:

95%

definition in the text.

That means a compliance team should be cautious about inventing a numeric safe harbor.

The better file documents:

• investment policy
• actual portfolio
• temporary cash flows
• exceptions
• reasons for any nonqualifying holdings.

The further the portfolio drifts from a short-term account, the weaker the reliance.

Multiple-Employer Plans Have Their Own Provision

Section I(b) addresses transactions involving an employer or employer affiliate whose employees participate in a multiple-employer plan.^[2]

The rule uses:

• pooled-account concentration
• the ERISA definition of substantial employer

in determining relief.

The provision reflects a different structural problem.

A multiple-employer plan itself contains several employers.

The exemption therefore cannot analyze employer influence using only the same-employer aggregation rule designed for a single sponsoring organization.

The Special Employer-Security and Real-Property Rules Matter When 10% Relief Is Unavailable

PTE 90-1 contains additional provisions for:

• employer securities
• employer real property.^[2]

These provisions are more technical than the ordinary party-in-interest route.

They matter because a plan's fractional interest in a pooled account can cause the plan to be treated as indirectly holding its employer's securities or real estate.

ERISA Section 407 separately limits securities issued by the employer and qualifying employer real estate.^[9]

PTE 90-1 prevents pooling from creating mechanical violations in defined circumstances.

Excess Holdings Can Be Caused by Aggregation

Section I(c) addresses a plan's acquisition or holding of qualifying employer securities or employer real property outside the pooled account when the problem exists solely because those direct holdings are aggregated with employer securities or real property held through the pooled separate account.^[2]

The logic is important.

Suppose a plan directly holds employer stock.

The pooled account also owns a diversified portfolio containing a small amount of that employer's stock.

The plan's attributed fractional share of the pooled holding can change its Section 407 calculation.

The exemption has a targeted rule for that interaction.

Employer Securities and Real Property Have a Separate Route

Section I(d) can provide relief for specified acquisitions, sales, holdings or leases involving sponsor-related securities and real estate even when the pooled account does not meet the ordinary Section I(a) or multiple-employer Section I(b) conditions.^[2]

That route is not automatic.

Among the conditions:

• no commission paid to the insurance company
• no commission paid to the employer or employer affiliate in connection with the specified acquisition, sale or lease
• additional property or security conditions apply.^[2]

The details matter because this is no longer the simple 10% route.

Employer Real Property Must Be Commercially Diversifiable

For the special real-property provision, each parcel and its improvements must be:

• suitable for use by different tenants, or
• adaptable to such use without excessive cost.^[2]

The pooled account's property that is leased or held for lease to others must also be geographically dispersed in the aggregate.^[2]

These conditions push the structure toward institutional investment real estate.

They reduce reliance on a single purpose-built property tied economically to one employer.

Example: Adaptable Office Property vs. Employer-Specific Facility

Property A

Multi-tenant office building.

Can be leased to:

• professional firms
• technology company
• healthcare operator.

If current employer tenant leaves, the property can be re-leased without extraordinary conversion expense.

Property B

Highly specialized manufacturing facility designed around one employer's proprietary equipment and process.

Alternative use requires:

$40 million

of reconstruction.

Property A fits the diversification concept more naturally.

Property B raises a much harder question under the special rule.

Employer Obligations Have Additional Concentration Conditions

For specified employer debt obligations, the exemption includes conditions that can depend on whether the pooled account already owns the obligation when the plan enters and, in another route, how much of the issue is held and who else holds restricted securities.^[2]

One stated structure limits the plan's holding immediately after acquisition to no more than:

25%

of the aggregate outstanding obligations of the issue.

For a restricted security within Rule 144, at least:

50%

of the relevant aggregate amount must be held by persons independent of the issuer under the exemption's stated framework.^[2]

These percentages solve a different problem from the 10% pooled-account test.

Do not mix them.

Section II Gives Specific Operational Relief

Section II goes beyond the basic exemption for several recurring transactions.^[2][3]

The 2025 DOL information-collection notice summarizes five categories:

1. furnishing goods connected to pooled-account real property
2. leasing pooled-account real property
3. transactions with parties in interest that have only specified service-provider relationships
4. insurer or affiliate management of pooled-account real property
5. services, facilities and incidental goods supplied by a public accommodation owned by the account.^[3]

Each category has its own logic.

Real-Property Goods and Leases Use a Different Dollar Test

Section II(a) applies to specified goods and leasing transactions involving pooled-account real estate.^[2]

The annual amount with that counterparty and its affiliates cannot exceed the larger of:

$25,000

or:

0.5% of pooled-account fair market value

measured using the most recent valuation date before the transaction.^[2]

This threshold is not the general 10% participation test.

It is a transaction-size condition for a specialized category.

Example: Greater-of Test

Pooled account value:

$200 million.

0.5%:

$1 million.

Greater of:

• $25,000
• $1 million

is:

$1 million.

The covered annual amount for that counterparty group must remain within the applicable limit.

Now consider a smaller:

$2 million

pooled account.

0.5%:

$10,000.

The floor is:

$25,000.

The greater-of formula matters.

Service-Provider Parties in Interest Can Receive Targeted Relief

Section II(b) addresses a counterparty that is a party in interest because it:

• provides services to the plan, or
• has a specified relationship to a service provider.^[2]

The relief depends on the person having no prohibited discretionary authority, control, responsibility or influence over:

• investment of plan assets into the pooled separate account
• management or disposition of plan assets held in the pooled account.^[2]

The person also cannot be an affiliate of the insurance company.^[2]

This is designed for a service relationship.

Not an investment-control relationship.

Example: Recordkeeper vs. Investment Decision Maker

Company R is recordkeeper to Plan A.

Company R has no authority over:

• whether Plan A invests in the pooled account
• what securities the account buys
• what assets are sold.

The pooled account enters a commercial transaction with Company R.

Section II(b) may be relevant if every condition is satisfied.

Change the facts.

Company R also has discretion to select the pooled account's investments.

Now the nondiscretionary-service-provider premise breaks down.

The exemption should not be read past its role limitation.

Real-Property Management by the Insurer Is an At-Cost Exemption

Section II(c) permits specified services by the insurance company or its affiliate in managing pooled-account real-property investments if compensation does not exceed:

the cost of the services to the insurer or affiliate.^[2]

That is not:

reasonable market compensation.

It is an at-cost condition.

Suppose internal property-management cost is:

$400,000.

Normal third-party market fee would be:

$650,000.

Charging $650,000 because it is market competitive does not fit an exemption condition capped at cost.

The distinction is deliberate.

Public Accommodations Can Serve Parties in Interest

A pooled separate account can own:

• hotel
• parking facility
• recreational facility
• another place of public accommodation.

Section II(d) allows the facility to furnish services, facilities and incidental goods to a party in interest when they are furnished on a basis comparable to the general public.^[2]

That is practical.

A company executive whose employer participates in the account should not have to avoid a hotel merely because the hotel sits in the pooled portfolio.

The condition is parity.

Example: Hotel Room

Pooled account owns Hotel H.

Market room rate:

$300.

Employee of a participating employer books a room for:

$300

under the same public terms.

That fits the logic of the public-accommodation relief.

If the employee receives:

free luxury suite + private event services

solely because the employer's plan invests in the pooled account, the facts are different.

Public availability is not permission for preferential insider benefits.

Every Exempt Transaction Needs Arm's-Length Economics

Section III(a) applies a general condition at:

• transaction entry
• any later renewal requiring insurer consent.^[2]

Terms cannot be less favorable to the pooled separate account than terms generally available in arm's-length transactions between unrelated parties.^[2]

That is one of the most important controls in the exemption.

PTE 90-1 tolerates indirect relationships.

It does not tolerate inferior economics.

Arm's-Length Review Should Be Transaction Specific

For a bond purchase, compare:

• price
• spread
• liquidity
• market quotes.

For a loan:

• interest rate
• collateral
• covenants
• maturity
• fees.

For a real-estate lease:

• rent
• escalators
• tenant improvement allowance
• term
• renewal options
• credit support.

For a service contract:

• scope
• fee
• quality
• termination rights.

A generic annual statement that:

all transactions are market based

is weaker than evidence matched to the actual asset type.

Six Years of Records Are a Condition

The insurer must maintain records necessary to determine whether exemption conditions were met for:

six years from the transaction date.^[2][3]

The current DOL information-collection process continues to treat that recordkeeping rule as a central compliance requirement.^[1][3]

The rule is not designed only for government examiners.

It also supports oversight by people whose plans are economically exposed to the pool.

Who Can Inspect the Records?

The exemption provides inspection access during normal business hours at the customary location to specified persons, including:

• authorized DOL representatives
• IRS representatives
• fiduciaries with authority to acquire or dispose of the plan's pooled-account interest
• contributing employers
• participants
• beneficiaries
• authorized representatives of those persons.^[2]

The access is not unlimited.

Trade secrets and privileged or confidential commercial or financial information are protected from inspection by the nongovernmental groups specified in the exemption.^[2]

A Six-Year File Needs More Than Trade Confirmations

A practical compliance file should include:

• counterparty identity
• party-in-interest relationship
• insurer-affiliate check
• same-employer plan aggregation
• pooled-account valuation
• sponsor-group percentage
• transaction economics
• market comparison
• specialized short-term-account eligibility where relevant
• Section II category if used
• annual limit calculation
• employer-security/property analysis if relevant
• approvals
• governing investment policy
• transaction date
• renewal date
• supporting pricing data.

A trade ticket proves execution.

It does not prove exemption eligibility.

Pooled Separate Accounts Can Be Form 5500 Direct Filing Entities

DOL's EFAST guidance recognizes a:

Pooled-Separate Account (PSA)

as a Direct Filing Entity category for Form 5500 purposes.^[11]

That reporting structure reflects the operational reality of the vehicle.

Many plans can participate in one pool.

The insurer can file information for the pooled vehicle using the applicable DFE framework rather than forcing each participating plan to reproduce the same underlying asset schedule independently where the reporting rules permit.

Reporting status and PTE status are related concepts but not identical legal tests.

PTE 90-1 vs. a Dedicated Separate Account

INV-146 addresses the broader separate-account terminology and manager structure.

PTE 90-1 is the deeper legal layer for one specific pooled insurance implementation.

PTE 90-1 vs. PTE 91-38

PTE 91-38 is the parallel class exemption for:

bank collective investment funds.^[1][10]

DOL amended PTE 80-51 and redesignated it PTE 91-38 after the insurance pooled-account exemption had already moved to the 10% structure.^[10]

The two exemptions solve nearly the same institutional problem through different regulated vehicles.

A plan cannot choose between them by preference after the trade.

The legal vehicle determines which exemption is relevant.

PTE 90-1 vs. PTE 95-60

PTE 95-60 covers:

insurance company general accounts.^[1]

A general account and a separate account are not two labels for the same balance sheet.

In a general account:

• assets support the insurer's broader contractual obligations
• plan rights are typically contractual claims against the insurer
• plan-asset treatment follows different rules.

In a qualifying separate account whose investment performance passes through, ERISA can treat the underlying portfolio assets as plan assets.^[5]

That difference changes the prohibited-transaction analysis.

Separate-Account Risk Is More Portfolio Specific

DOL regulations discussing insurance arrangements note that separate-account assets are segregated from general assets and investment results can be passed through directly to policyholders, depending on contract terms.^[5]

For the plan fiduciary, that means risk analysis focuses heavily on:

• underlying portfolio
• manager
• liquidity
• valuation
• asset concentration
• transaction conflicts.

A general-account contract places more of the economic focus on:

• insurer contractual promise
• general-account financial strength
• contract guarantees.

PTE 90-1 belongs to the first structure.

PTE 90-1 vs. QPAM

PTE 84-14 follows an:

independent qualified professional asset manager.

PTE 90-1 follows an:

insurance pooled separate account.

That difference affects compliance.

QPAM route

Ask:

• Is the manager a qualifying QPAM?
• Did the QPAM make the decision?
• Is the counterparty related to the QPAM?
• Are QPAM concentration and other conditions satisfied?

Pooled-account route

Ask:

• Does the vehicle fit the insurer-maintained pooled-account structure covered by the exemption?
• Is the counterparty excluded because it is the insurer or affiliate?
• Does the employer-group interest fit the 10% route or specialized alternative?
• Are PTE 90-1 transaction conditions met?

The same transaction can sometimes fit more than one exemption.

The file should identify the exemption actually relied on.

QPAM Is Not Mandatory Just Because the Pool Holds Plan Assets

A common shortcut says:

all institutional ERISA transactions need a QPAM.

That is wrong.

DOL has created several vehicle- and manager-based exemptions.

PTE 90-1 exists precisely so a qualifying insurance pooled account can receive broad relief under its own conditions.^[1][2]

Using QPAM status as an additional backstop can be useful in some structures.

It is not a prerequisite written into PTE 90-1.

Exemption Choice Should Be Deliberate

Suppose an insurer's pooled account buys private notes issued by Company X.

Company X is a party in interest to one participating plan.

Possible legal file:

Route A — PTE 90-1

Document:

• pooled separate-account status
• insurer relationship
• sponsor-group interest under 10%
• arm's-length price
• records.

Route B — QPAM

If available, document the separate PTE 84-14 conditions.

The transaction does not become more compliant because a memo lists:

PTE 90-1 / PTE 84-14 / PTE 91-38 / all other available exemptions.

That usually signals nobody determined which one applies.

The 2002 Amendment Clarified the Word "Plan"

PTE 2002-13 amended a group of older exemptions to clarify that references to:

employee benefit plan

and:

plan

include plans described in ERISA Section 3(3) and/or Code Section 4975(e)(1), as applicable.^[4]

PTE 78-19, as amended and redesignated PTE 90-1, was among the exemptions addressed.^[4]

That matters because the prohibited-transaction regime is not limited to Title I corporate 401(k) plans.

The exact investor population should be identified.

PTE 90-1 Did Not Need the 2016/2024 Fiduciary-Advice Cleanup

Several recent RFPPs required careful reconstruction after DOL's:

• 2016 fiduciary-rule amendments
• 2024 Retirement Security amendments
• later court vacaturs.

PTE 90-1 was not one of the mass-amended exemptions in those advice packages.

Its core modern structure remains the 1990 pooled-account framework, with the later plan-definition clarification.^[1][2][4]

That makes the current-law analysis cleaner than PTE 77-4, PTE 80-83, PTE 83-1, PTE 84-24 or PTE 86-128.

DOL Still Lists the Exemption as Active

DOL's current class-exemption page lists:

Insurance Company Pooled Separate Accounts, PTE 1990-01.^[1]

It states that the exemption:

• amended and superseded PTE 78-19
• expanded the permissible participating-plan percentage
• added relief for investments in short-term obligations issued by parties in interest.^[1]

OMB Control Number:

1210-0083.

Current expiration:

April 30, 2028.^[1]

That expiration date relates to the information collection.

Not the substantive exemption.

OMB Expiration Is Not Exemption Expiration

The six-year recordkeeping obligation is an information collection subject to Paperwork Reduction Act approval.^[1][3]

OMB approvals periodically expire and are renewed.

April 30, 2028 should therefore be read as:

current paperwork-approval date

not:

PTE 90-1 terminates in 2028.

Those are different legal events.

PTE 90-1 Does Not Make the Pooled Vehicle Prudent

ERISA Section 404 still requires fiduciaries to act prudently and loyally.^[7]

The 1990 exemption itself expressly notes that administrative relief does not eliminate fiduciary responsibility.^[2][8]

A plan can satisfy the 10% test and still select a weak vehicle.

Fiduciary review should separately address:

• investment strategy
• manager quality
• fees
• liquidity
• valuation
• diversification
• leverage
• securities lending
• derivatives
• real estate exposure
• exit mechanics
• insurer operational risk.

The PTE solves legal friction.

Not investment quality.

The 10% Threshold Is Not a Diversification Standard

Suppose a plan holds:

8%

of the pooled account.

The pooled account itself holds:

45%

in one illiquid real-estate strategy.

The PTE concentration test can be satisfied.

The portfolio can still be poorly diversified for the plan.

The 10% number answers:

How concentrated is this employer group inside the pooled vehicle?

It does not answer:

How diversified is the vehicle?

Those are different denominators and different fiduciary questions.

Low Fees Do Not Cure Weak Governance

Pooled separate accounts can offer institutional pricing.

Assume:

• management fee: 0.12%
• comparable mutual fund: 0.25%.

The pooled account appears cheaper by:

13 basis points.

But plan should also examine:

• contract charge
• custody
• audit
• unitization
• recordkeeping
• transition cost
• exit restrictions
• securities-lending allocation.

A lower stated management fee can be attractive.

It does not replace a total-cost review.

The Plan Fiduciary Still Has to Monitor the Insurer

PTE 90-1 places transaction-level conditions on the insurer.

The plan fiduciary's job is broader.

A monitoring process should ask:

• Does the account remain consistent with mandate?
• Is performance explainable?
• Are fees competitive?
• Is liquidity adequate?
• Has ownership concentration changed?
• Has the plan's own percentage of the pool increased?
• Are there material insurer conflicts?
• Is the plan still receiving sufficient reporting?

Vehicle-level exemption compliance is not a reason to outsource judgment entirely.

The ROIStreet Pooled Separate Account Review Map

Layer 1: Identify the vehicle

Is it actually:

the insurer-maintained pooled vehicle covered by PTE 90-1

rather than:

• dedicated separate account
• insurance general account
• bank CIT
• mutual fund
• private fund?

Layer 2: Map plan assets

Does the plan-asset regulation treat the underlying separate-account assets as plan assets?

Layer 3: Map the counterparty

Is it:

• a party in interest to one participating plan?
• the insurer?
• another insurer separate account?
• an insurer affiliate?
• a nondiscretionary service provider?

Layer 4: Select exemption path

• ordinary 10% route
• specialized short-term account
• multiple-employer route
• employer-security/property route
• Section II specific relief
• another exemption.

Layer 5: Prove economics

Are terms at least as favorable as unrelated-party arm's-length terms?

Layer 6: Preserve records

Can the insurer reconstruct the analysis six years later?

Layer 7: Re-run fiduciary review

Would the plan still choose this pooled account if no prohibited-transaction exemption were needed?

That last question separates legal availability from investment merit.

A Practical PTE 90-1 Transaction Test

Confirm the vehicle fits PTE 90-1's pooled insurance structure → determine whether underlying assets are plan assets → identify every participating plan related to the employer or employee organization whose relationship creates the party-in-interest issue → aggregate those related plan interests → calculate sponsor-group assets as a percentage of total pooled-account assets → if relying on Section I(a)(1), confirm the percentage does not exceed 10% for the current transaction timing → if relying on the specialized short-term route, confirm governing policy and actual portfolio are substantially short-term and each relevant obligation fits the one-year maturity framework → identify the counterparty → confirm the counterparty is not the insurer maintaining the account, another separate account of that insurer or an insurer affiliate under the ordinary general route → identify which ERISA prohibition is implicated → do not assume Section I solves Section 406(b)(1) or (3) → test multiple-employer provisions where applicable → for employer securities or real property, identify the exact Section I(c)/(d) route and its additional conditions → for Section II goods/lease relief, calculate the applicable annual dollar floor versus the 0.5% asset-based amount → for service-provider relief, confirm the counterparty lacks prohibited discretionary authority or influence → for insurer real-property management, confirm compensation does not exceed cost → for public accommodations, confirm terms are comparable to those available to the public → benchmark transaction economics against unrelated-party terms → preserve compliance records for six years → monitor changes in plan contributions and sponsor-group concentration → document Section 404 investment merit separately

The right question is not:

"Is this an insurance separate account?"

It is:

"Is this the pooled structure PTE 90-1 was written for, does the exact transaction fit one of its relief paths, and can the insurer and plan fiduciary prove both exemption compliance and independent investment merit?"

Frequently Asked Questions

What does PTE 90-1 cover?

It provides class relief for specified transactions involving insurance company pooled separate accounts in which employee benefit plans invest, including many transactions with parties in interest and specified employer-security or employer-real-property holdings.^[1][2]

Is every insurance separate account covered?

No. The exemption is designed for an insurer-maintained pool holding assets for multiple plans. A dedicated one-plan mandate is a different structure.

Why are underlying pooled assets treated as plan assets?

The plan-asset regulation generally treats a plan investing in an insurance-company separate account as holding an undivided interest in the account's underlying assets, subject to the fixed-contractual-obligation exception.^[5]

What is the current percentage limit?

For current transactions under the ordinary route, the combined interest of the relevant sponsor group's plans generally cannot exceed 10% of total pooled-account assets.^[2]

Can related plans be tested separately?

No. Plans tied to the same sponsoring employer or employee organization are aggregated for this calculation.^[2]

Is 10% measured against total assets of the employer's retirement plans?

No. The denominator is the total value of the pooled vehicle.

Can a specialized short-term account exceed the ordinary 10% threshold?

Section I(a)(2) provides an alternative route for a specialized account with a policy of investing, and that invests, substantially all assets in qualifying short-term obligations.^[2]

What counts as short term?

The exemption uses obligations with a stated maturity of one year or less or a maturity one year or less from the date the specialized account acquires them.^[2]

Does a five-year bond qualify if the manager plans to sell it quickly?

Not merely because of expected holding period. The provision is written around maturity.

Can the pooled account transact freely with the insurer?

Not under the ordinary Section I(a) general relief. The insurer maintaining the account, its other separate accounts and its affiliates are excluded counterparties.^[2]

Does the basic exemption cover fiduciary self-dealing?

It provides specified relief including Section 406(b)(2), but it should not be read as blanket relief from Section 406(b)(1) or Section 406(b)(3).^[2][6]

Does PTE 90-1 cover employer stock?

It contains specific relief for sponsor-related securities and real estate, but those conditions are technical and differ from the ordinary general route.^[2][9]

What is the $25,000 or 0.5% rule?

For specified Section II real-property goods and lease arrangements, compare the $25,000 floor with 0.5% of pooled-account fair market value; the larger figure is the annual cap for the relevant counterparty group.^[2]

Can a plan service provider transact with the pool?

Section II includes targeted relief for a person whose party-in-interest status arises from specified service-provider relationships when that person lacks the prohibited discretionary authority, control or influence and is not an insurer affiliate.^[2]

Can the insurer charge a market property-management fee?

The specific Section II(c) relief for insurer or affiliate management of pooled-account real property caps compensation at the cost of those services.^[2]

Can a party in interest use a hotel owned by the pool?

The public-accommodation provision can apply when services, facilities and incidental goods are furnished on a basis comparable to the general public.^[2]

What pricing standard applies?

At transaction entry and specified renewals, terms cannot be less favorable to the pooled account than those generally available in arm's-length transactions between unrelated parties.^[2]

How long must records be retained?

Generally six years from the transaction date.^[2][3]

Who can inspect the records?

Specified DOL and IRS representatives, relevant plan fiduciaries, contributing employers, participants, beneficiaries and their authorized representatives have inspection rights subject to the exemption's confidentiality limitations.^[2]

Is a pooled separate account a Form 5500 Direct Filing Entity?

DOL recognizes a Pooled-Separate Account as a DFE category for Form 5500 purposes.^[11]

What is the difference between PTE 90-1 and PTE 91-38?

PTE 90-1 applies to insurance company pooled separate accounts. PTE 91-38 is the parallel exemption for bank collective investment funds.^[1][10]

What is the difference from PTE 95-60?

PTE 95-60 applies to insurance company general accounts, not pooled separate accounts.^[1]

Does the insurer need to be a QPAM?

Not as a condition of PTE 90-1 itself. QPAM relief is a separate exemption route.

Was PTE 90-1 changed by the 2016 or 2024 fiduciary-advice rules?

It was not one of the exemptions rewritten in those mass fiduciary-advice amendment packages. Its core modern structure remains the 1990 pooled-account framework, with the 2002 plan-definition clarification.^[1][2][4]

Is the exemption still active?

Yes. DOL currently lists PTE 1990-01 and OMB Control No. 1210-0083 through April 30, 2028.^[1]

Does April 30, 2028 mean the exemption expires?

No. That date is the current expiration of the OMB information-collection approval, not an automatic sunset of the substantive exemption.

Does compliance prove the pooled account is prudent?

No. ERISA Section 404 prudence and loyalty duties remain separate.^[7][8]

Educational Disclaimer

ROIStreet publishes educational content about retirement-plan fiduciary duties, insurance company separate accounts, pooled investment vehicles and ERISA prohibited-transaction exemptions. This article is not legal, fiduciary, insurance, securities, tax, investment or plan-administration advice. PTE 90-1 is highly fact-specific. Availability depends on the legal vehicle, participating-plan relationships, sponsor-group concentration, counterparty identity, insurer affiliation, transaction type, short-term-account status, employer securities or real property, pricing, services, compensation, valuation timing and records. An exempt transaction can still be imprudent, disloyal or economically unattractive.
