NAIC's New Reinvestment Floor Rewrites PBR Reserve Math for VM-20, VM-21, VM-22

The NAIC's Life Actuarial (A) Task Force adopted Amendment Proposal Form 2025-16 at the Spring 2026 San Diego meeting, replacing the single prescribed reinvestment quality assumption in VM-20, VM-21 and VM-22 with a minimum floor of 50% A-quality and 50% AA-quality. The Life Insurance and Annuities (A) Committee ratified it on July 13, 2026.

That converts a lookup into a judgment call. Which balance sheets it relieves depends entirely on what the company actually owns.

Key Takeaways

A floor replaces a fixed point. Companies may model any reinvestment blend above 50% PBR credit rating 6 and 50% PBR credit rating 3, consistent with their own modeled investment strategy.
A BBB-referenced spread plus 0.5 percentage points of illiquidity premium governs income credited on reinvested assets, capping the yield a company can claim by reaching down in quality even at the floor.
Conservatively invested carriers get the relief. A general account already clearing the A/AA bar can model a richer reinvestment yield, producing a lower stochastic reserve than the prior single prescribed assumption.
Private-credit-heavy platforms sit at the floor, so the amendment leaves them where a stricter prescribed standard would have, with added documentation burden to show they are not below it.
$464.1 billion of US retail annuity sales in 2025 now sits on a reserve basis where the reinvestment assumption is a documented company choice rather than a regulatory default.

What APF 2025-16 Changes

Before the amendment, the fixed income reinvestment assumption in VM-20 Section 7.E.1.g, VM-21 Section 4.D.4.b and VM-22 Section 4.D.3.b specified one credit-quality blend every company applied identically when projecting reinvestment of maturing and net cash flow assets in stochastic scenarios. Regardless of actual investment strategy, the reserve model reinvested new money at a prescribed mix, with no latitude to reflect whether a company genuinely bought high-grade corporates, structured credit, or a barbell of both.

APF 2025-16 substitutes a floor for that point. Any blend above 50% PBR credit rating 6, roughly an A2/A agency rating, and 50% PBR credit rating 3, roughly Aa2/AA, is now permissible if expressed as a weighted average life consistent with the company's own modeled strategy. The American Council of Life Insurers ran field testing with the NAIC model office ahead of the vote, and the task force set a February 9, 2026 comment deadline before advancing to adoption.

The quality mix is only half of it. Insurers must also incorporate a prescribed spread and default assumption referenced to yields aligned with BBB-rated bonds, plus an additional 0.5 percentage point illiquidity premium, when calculating income credited on reinvested assets. That ties the assumed spread to a BBB benchmark rather than to a company's own observed portfolio yield, which caps the incremental yield available from reaching down in quality even at the floor.

The change was adopted over objection. One member said "the rationale for incorporating lower-rated investment benchmarks into reserve formulas was not sufficiently clear", and the American Academy of Actuaries flagged that the change could land unevenly across companies with materially different risk management frameworks. It applies broadly, pension risk transfer business included, regardless of the ceding company's asset allocation.

Framework	Where the guardrail lands	Practical effect of the floor change
VM-20	Deterministic and stochastic reserve for individual life	Net asset earned rate shifts across the full projection horizon; stochastic tail scenarios most affected
VM-21	Standard Scenario and CDHS/CTE calculation	Living-benefit rider guarantee cost versus modeled yield spread widens for higher-quality portfolios
VM-22	Stochastic reserve for non-variable and fixed indexed annuities, PRT	Interacts with existing aggregation debate; widens the defensible range of yield assumptions per cohort

Who Gets the Relief

The floor mechanic produces an asymmetry that tracks asset allocation rather than company size.

Carriers running conservative, investment-grade-heavy general accounts now have a defensible basis to model reinvestment yield above the old prescribed blend, because their real portfolios already clear a quality bar well north of 50% A and 50% AA. That translates into a lower net premium and a lower stochastic reserve than the same block would have produced under the prior single assumption, all else equal.

Carriers with heavy allocations to private credit, collateralized loan obligations and middle-market direct lending sit at or near the floor instead. Those assets typically carry PBR credit ratings below the blend the floor requires, so the real portfolio does not clear the bar that would permit a richer modeled yield. The relief flows disproportionately to conservatively invested carriers, while private-credit-heavy platforms are held where a stricter prescribed standard would have held them, and in some cases carry additional burden to justify why their modeled blend does not fall below the minimum.

The size of the effect differs by framework. In VM-20 the assumption feeds both the deterministic and stochastic reserve, and because the stochastic reserve typically binds for long-duration policies, a shift in reinvestment yield moves the net asset earned rate across a 30 to 50 year projection horizon rather than a near-term segment.

In VM-21 it flows into the Standard Scenario reserve and the CTE calculation, where living benefit riders are sensitive to the spread between crediting cost and modeled asset yield, so even a modest change can move the Standard Scenario floor many variable annuity blocks still bump against. In VM-22, fully effective for non-variable annuities in 2026, it compounds the existing aggregation debate by widening the range of defensible net asset earned rates inside the same stochastic model.

The work moves onto the valuation actuary accordingly. A blend chosen above the floor is an assumption decision documented and defended in the PBR actuarial memorandum the way mortality, lapse and policyholder behavior already are. Because the BBB-referenced spread and the illiquidity premium constrain the realizable benefit, the memorandum has to carry the full net asset earned rate calculation rather than the credit-quality assumption alone.

Both Sides of an Offshore Treaty Now Move Differently

The amendment lands on top of the scrutiny already applied to offshore life and annuity reinsurance, and it pushes the two sides of a treaty in opposite directions.

When a US carrier cedes a block to a Bermuda-based affiliate, investment management authority frequently transfers alongside the reserve liability, so the assuming entity's asset strategy becomes the operative portfolio for reinvestment modeling. AG 55's asset adequacy and reserve credit controls were built around that concern: ceded reserves should reflect the economics of the assuming company's balance sheet rather than a favorable modeling assumption.

On the ceding side, a US company retaining a high-quality general account can now model a richer reinvestment yield under the floor, reducing gross reserves before cession. On the assuming side, an offshore reinsurer whose actual strategy sits near the 50/50 floor because of private credit allocation cannot support the same assumption, so the reserve credit calculation has to reflect the lower-quality reality rather than importing the cedant's number. The two calculations that used to run off one prescribed blend now diverge by construction, and they diverge most where the asset strategies differ most.

The scale makes the drafting consequential rather than technical. US carriers wrote $464.1 billion in retail annuity sales in 2025, and every contract written under VM-22, along with every life policy under VM-20 and every variable annuity under VM-21, now sits on a reserve basis where a company-specific choice replaced a regulatory default. The floor bounds how far that choice can go in one direction. It does not bound how far apart two companies' answers can sit.
