A number of readers have asked me to explain what their earnings become after the money is sent to Principal Insurance Company. They are having problems fully understanding the process. Below is my answer.
What Your monthly “premium” Is Actually Paying For after it leaving your earnings statement
In a 401(k) Group Variable Annuity (GVA) issued by an insurance company. In a 401(k) GVA, your “premium” is not paying for insurance. It is paying for participation in an insurer‑owned investment account.
There is no mortality risk,
no longevity guarantee,
no insurer‑backed payout obligation,
no general‑account guarantee,
no annuity income promise,
and no insurance protection of any kind.
Yet the insurer still calls your contribution a premium, and still calls the accounting unit you receive a unit of value — both terms borrowed from insurance law, not securities law.
This is the core structural mismatch.
What You Actually Receive: “Units of Value”
A unit of value in a Principal GVA is:
• Not a share of a mutual fund
• Not a security priced in a public market
• Not governed by SEC valuation rules
• Not priced by an independent pricing agent
• Not subject to federal audit of valuation methods
Instead, it is:
A synthetic accounting unit created by the insurer, valued by the insurer, inside an insurer‑owned separate account.
Participants do not own the underlying assets.
Participants own only a contract value, expressed in these synthetic units.
This is why insurers can:
• Freeze transfers
• Restrict withdrawals
• Change valuation methods
• Impose market value adjustments
• Reprice units without external oversight
And they can do all of this without violating securities law, because the product is not regulated as a security.
Why the IRS Allows This Structure
The IRS supports tax‑deferral for:
• 401(k) salary deferrals
• Employer contributions
• Qualified retirement annuity contracts
Insurance companies exploited the “annuity contract” category to insert GVA products into the 401(k) ecosystem beginning in the early 1980s.
But here’s the key:
The IRS only governs tax treatment — not valuation, not pricing, not fiduciary conduct, not investor protection.
So the IRS blessing does not mean the product is insurance.
It only means the contributions are tax‑deferred.
- Workers contribute ~10% of wages as “premiums”
• They believe they are buying something regulated like insurance or securities
• But they are actually buying synthetic units in an insurer‑controlled investment pool
• With no federal valuation standards
• No independent pricing
• No market‑based NAV
• No guarantee
• No insurer risk
• And no transparency
Variable annuities are tax‑deferred in a 401(k) because the 401(k) is tax‑deferred — not because the annuity is.
The annuity wrapper adds:
• No tax benefit
• No insurance protection
• No regulatory advantage for the participant
But it adds significant regulatory advantages for the insurer, which is why the structure persists.
Here’s the clearest, most regulator‑ready explanation of why insurers fight to keep Group Variable Annuities inside 401(k)s — and why the structure persists even though it provides no tax benefit and no insurance protection to participants.
This is the part almost no one in Washington understands until it’s laid out step‑by‑step.
Why the Variable Annuity Wrapper Gives Insurers Enormous Regulatory Advantages
- Avoids SEC Regulation Entirely
A mutual fund or pooled investment vehicle used in a 401(k) would normally be:
• Registered with the SEC
• Priced using market‑based NAV
• Audited under federal securities law
• Required to disclose holdings
• Required to use independent pricing agents
• Subject to antifraud rules
• Required to provide prospectuses and filings
But a Group Variable Annuity is classified as an insurance contract, not a security.
That means:
The insurer escapes SEC oversight of the investment pool.
This is the single biggest regulatory advantage.
- Allows Insurer‑Controlled Valuation (Synthetic Unit Pricing)
Because the product is not a security:
• No independent pricing
• No market‑based NAV
• No public disclosure of valuation methods
• No requirement to mark assets to market
• No federal audit of valuation systems
• No requirement to disclose losses at the property level
This is why insurers can use internal systems like SAIN to generate synthetic unit values.
The insurer controls the price of the units participants receive.
No mutual fund could legally do this. - Avoids Federal Fiduciary Standards
ERISA fiduciaries must act:
• Solely in the interest of participants
• With prudence
• With loyalty
• With transparency
But insurers are not ERISA fiduciaries when they:
• Value the separate account
• Price the units
- Manage the assets
• Impose restrictions
• Delay withdrawals
• Reprice units after losses
Why?
Because they classify themselves as product manufacturers, not fiduciaries.
The annuity wrapper shields insurers from ERISA fiduciary liability.
- Avoids Federal Accounting and Audit Standards
Mutual funds and CITs must follow:
• GAAP
• SEC valuation rules
• Independent audits
• Public reporting
Insurer separate accounts used in GVAs:
• Are not audited under federal securities law
• Are not required to publish financial statements
• Are not required to disclose asset‑level losses
• Are not required to use independent valuation agents
The insurer controls the accounting environment. - Avoids State Insurance Solvency Rules for the Separate Account
This is the irony:
• The insurer calls it “insurance” to avoid SEC oversight
• But the separate account is not treated like insurance for solvency protection
State regulators:
• Do not regulate investment risk
• Do not regulate unit pricing
• Do not regulate valuation methods
• Do not regulate participant protections
• Do not regulate liquidity risk
They only regulate insurer solvency, not investor protection.
The insurer gets the benefits of the insurance label without the burdens of insurance regulation. - Allows Withdrawal Restrictions That Would Be Illegal in a Security
Because it’s an “annuity contract,” insurers can:
• Freeze transfers
• Delay withdrawals
• Impose market value adjustments
• Restrict liquidity
• Smooth losses
• Delay recognition of asset impairments
A mutual fund cannot legally do this.
The annuity wrapper gives insurers unilateral control over participant liquidity.
- Allows Insurers to Capture Spread, Float, and Hidden Fees
Because the product is not a security:
• Fees do not need to be disclosed like mutual fund fees
• Spread revenue can be embedded in unit pricing
• Asset‑level losses can be smoothed or deferred
• Participants cannot see the underlying portfolio
• Insurers can retain gains from timing differences
The insurer monetizes opacity. - Avoids Federal Oversight of the Underlying Assets
The assets inside the separate account:
• Are not subject to SEC custody rules
• Are not subject to federal valuation rules
• Are not subject to federal liquidity rules
• Are not subject to federal disclosure rules
This is why insurers can hold:
• Illiquid real estate
• Private placements
• Internal loans
• Affiliated investments
• Hard‑to‑value assets
The insurer can invest in ways mutual funds cannot.
The Bottom Line
The variable annuity wrapper is not used because it benefits participants.
It is used because it shields insurers from federal oversight.**
It allows insurers to:
• Control valuation
• Control pricing
• Control liquidity
• Control disclosure
• Control accounting
• Control risk recognition
• Avoid SEC regulation
• Avoid ERISA fiduciary duties
• Avoid federal audit standards
• Avoid transparency requirements
And because the IRS provides tax deferral at the plan level, not the product level, insurers get all these advantages without giving up anything.
This is why the structure persists.
