The PE-Insurance Nexus: A Systemic Risk Thesis

Over the past decade, the largest private equity firms have systematically acquired or built insurance subsidiaries — Apollo (Athene), KKR (Global Atlantic), Blackstone (F&G partnership), Carlyle (Fortitude Re), Brookfield (AEL). The structure creates a self-reinforcing capital loop that is inadequately captured by current regulatory frameworks.

The loop works as follows: a PE firm acquires an insurer or annuity platform, gaining access to its long-duration liability base (policyholder reserves). Those reserves are then reallocated away from traditional investment-grade bonds and into the PE firm's own private credit funds, CLOs, real estate vehicles, and direct lending products — generating management fees and carried interest for the same PE firm that owns the insurer. The insurer's general account simultaneously serves as both the capital base and the deployment vehicle for the PE sponsor's asset management business.

This creates three compounding risks: (1) valuation opacity — alternatives are Level 3 assets marked by the same manager who profits from higher marks; (2) liquidity mismatch — annuity liabilities require reliable cash flows while alternatives are inherently illiquid; (3) regulatory arbitrage — NAIC RBC charges assign low capital requirements to securities that NAIC designates as investment grade, even when those designations fail to capture the true economic risk of PE-originated private credit and structured products. The result is stated RBC ratios that may significantly overstate actual capital adequacy.

Step 1
PE Firm Acquires Insurer
Apollo → Athene • KKR → Global Atlantic
Blackstone → F&G (partnership) • Carlyle → Fortitude Re
Step 2
Insurer Allocates to PE Products
General account reserves deployed into PE-managed CLOs, private credit, real assets — earning the PE firm a second layer of fees
Step 3
PE Products Back the Insurer
Insurer's capital adequacy (RBC) partly depends on the performance of assets managed by its own owner — creating a circular dependency

Why the NAIC Framework Is Structurally Inadequate

NAIC Designation vs. Reality
PE-originated private credit and CLO tranches frequently receive NAIC 1 or NAIC 2 designations through the filing exempt process — often based on manager representations rather than independent ratings. The low RBC charge (0.3% for NAIC 1) dramatically understates capital needed for these assets. Moody's and S&P have no role in the designation process for many of these securities.
Schedule BA Opacity
Schedule BA captures "other long-term assets" — the catch-all for private equity, hedge funds, real estate, and infrastructure. Disclosure is minimal: asset names, book values, and a percentage of total. Market values are not required. The assets are carried at cost or amortized cost, making it impossible to assess true economic impairment from public disclosures alone.
Shadow Insurance / Captive Reinsurance
Insurers cede blocks of business to affiliated offshore entities (Bermuda, Cayman) that hold assets under less stringent regulatory requirements than U.S. state law demands. The cedant's statutory balance sheet looks stronger because the reserves have moved off — but the insurer remains economically on the hook if the captive fails. The NAIC's 2016 "Actuarial Guideline 48" was a partial fix, but structures continue to evolve around it.
State-by-State Fragmentation
Insurance regulation in the United States is state-level. There is no federal prudential supervisor. This means a PE firm can choose its insurer's domicile strategically — Iowa, Arizona, Indiana — to select regulators with the most permissive investment limitations and alternative asset flexibility. Regulatory arbitrage across state lines is a structural feature, not a bug, for PE-owned platforms.

Athene Holding / Apollo Global Management
APO (NYSE) — Life & Annuity Insurer — Merged into Apollo Jan 2022 — $440B+ Total Assets
Complete
Total Assets (2025) $440B+
Red Flags 14 — 9 score ≥7/10
FABN Exposure $64B outstanding — nearly doubled in 12 months
Self-Reinsurance $192B Bermuda affiliate (100% of Bermuda Re)

Apollo owns Athene, manages its assets, and marks its Level 3 valuations — a trifecta of conflicts with no equivalent in U.S. insurance history. 67% of the bond portfolio is private debt (Fitch); 50% of Q2 2024 new purchases had Apollo affiliation; AP Grange (Intel) holds ~20% of equity in a single deteriorating credit; Fox Hedge repackages Apollo fund equity into AA-rated insurance-eligible bonds via a 40-year Bermuda SPV. $64B in institutional FABN funding nearly doubled in 12 months. $192B in self-reinsurance via Bermuda affiliate with no independent counterparty. The platform is solvent by statutory measures — but those measures were not designed for this structure.

Priority Queue

3 targets — next phase
F&G Annuities & Life
FG (NYSE) — Annuity & Life Insurer — Majority-Owned by FNF Group — Blackstone as Largest Alternative Asset Manager
Priority #2
Total Assets ~$65B (Q3 2025)
Alternative Allocation ~17–20% in alternatives; Blackstone manages ~$10B+
AM Best / S&P A- (AM Best) · BBB+ (S&P) — Fidelity & Guaranty
AUM Growth Rate >150% growth since Blackstone partnership (2022)

Audit Thesis: F&G is the fastest-growing PE-adjacent insurer in the U.S. annuity market. Its strategic asset management agreement with Blackstone Credit & Insurance (BXCI) gives Blackstone discretion over a significant portion of the general account's alternative allocation — generating fees for Blackstone while providing F&G with access to yield-enhancing structured products. The fund is publicly traded, providing 10-K disclosure, but the affiliated investment structure creates the same circularity as Athene: Blackstone manages the assets, marks the assets (Level 3), and collects performance fees on those same assets. Rapid asset growth since 2022 raises underwriting-quality concerns: has the pace of general account deployment outstripped the ability to maintain credit discipline in private markets? Distribution coverage and surrender charge profile must be mapped against liquidity of underlying alternatives.

Global Atlantic Financial Group
Private (KKR-Owned) — Annuity, Life & Reinsurance — 100% KKR Acquisition Completed 2024 — ~$150B AUM
Priority #3
Total AUM ~$150B (2024)
Structure Life, annuity, reinsurance — KKR 100% since Jan 2024
AM Best A- (Excellent) — Global Atlantic Life Insurance Co.
Domicile Iowa (primary) · Bermuda (reinsurance affiliate)

Audit Thesis: KKR completed its 100% acquisition of Global Atlantic in January 2024, closing the loop entirely. Prior to full acquisition, KKR managed a significant portion of Global Atlantic's alternatives — now the same entity owns both the manager and the insurer. Global Atlantic is an active reinsurance counterparty, taking on legacy life and annuity blocks from other carriers — which means its liability profile is composed of complex, long-dated obligations that demand precise asset-liability matching. KKR's private credit and real asset platforms are the natural deployment vehicle for those reserves. The audit will focus on: (1) what proportion of the KKR-managed alternatives in the general account overlap with KKR's own fund products; (2) what is the actual composition of the reinsurance liability profile versus the duration of alternative assets; (3) has the full buyout materially changed the investment mandate relative to the minority-ownership era?

American Equity Investment Life (AEL)
AEL (NYSE) — Fixed & Indexed Annuity Insurer — Brookfield Asset Management Strategic Stake — ~$70B General Account
Priority #4
General Account ~$70B (2024)
Brookfield Stake ~19.9% economic interest + asset management agreement
AM Best / Fitch A- (AM Best) · BBB+ (Fitch) — American Equity Life
Product Mix 90%+ fixed & fixed-indexed annuities

Audit Thesis: AEL represents a slightly different structure: Brookfield holds a significant minority stake rather than full ownership, alongside a long-term asset management agreement granting Brookfield Investment Management discretion over a portion of the general account. This is the "partnership model" — common for Blackstone at F&G as well — which allows the PE firm to capture asset management economics without full balance sheet consolidation. Brookfield's focus on real assets (infrastructure, real estate, renewable power) means AEL's alternative allocation has a different risk profile than pure private credit — higher duration, more cyclical, with valuation dependent on interest rate assumptions. Fixed-indexed annuity liabilities have unique optionality costs (index crediting) that must be hedged precisely; if that hedge program has gaps, combined with illiquid real assets, the liquidity exposure is severe. The audit will quantify Brookfield's share of AEL's general account and test whether stated RBC ratios hold under a real-asset stress scenario.

Lincoln National Corporation
LNC (NYSE) — Publicly Traded Life & Annuity — ~$380B General Account (incl. VA)

Live Stress Signal: Lincoln National reported a $2.6B GAAP loss in Q3 2022 tied to a reserve strengthening on its legacy group protection and variable annuity blocks — one of the largest single-quarter reserve charges in U.S. insurance history. S&P downgraded Lincoln to BBB+ (negative outlook) in 2023. While not PE-owned, Lincoln's variable annuity book represents a textbook case of ALM failure: long-dated guarantees, insufficient hedging, and rate sensitivity that destroyed capital in the 2022 rate shock. Its recovery trajectory and current statutory surplus position warrant close examination.

Live Stress Signal
Jackson Financial / Jackson National Life
JXN (NYSE) — Publicly Traded — Spun off from Prudential plc (UK) 2021 — Largest U.S. Variable Annuity Writer

Jackson is the single largest writer of variable annuities in the United States, with $200B+ in separate account liabilities and a significant guaranteed minimum benefit exposure. Unlike PE-owned peers, the risk here is pure market and longevity risk: if equity markets decline and interest rates fall simultaneously, the cost of honoring VA guarantees rises sharply while the hedge book struggles to keep pace. The 2021 Prudential spinoff left Jackson capital-constrained at a critical point in the rate cycle. The general account's alternative allocation and Jackson Re's offshore structure round out the audit thesis.

Planned
Fortitude Re
Private (Carlyle-Backed) — Run-Off Life & Annuity Reinsurer — ~$55B in Liabilities — Bermuda-Domiciled

Fortitude Re was spun out of AIG in 2020 with Carlyle Group and T&D Holdings as investors. It is a pure legacy block run-off vehicle — acquiring long-dated, complex life and annuity liabilities from carriers seeking to de-risk their balance sheets. Carlyle then manages the assets backing those liabilities, creating the same PE fee-on-fee dynamic as Athene/Apollo. As a Bermuda-domiciled reinsurer, Fortitude's statutory disclosures are less transparent than U.S.-domiciled entities. The audit will focus on asset quality, Carlyle's share of investment management, and the structural solvency of the run-off model under adverse credit scenarios.

Planned
Brighthouse Financial
BHF (Nasdaq) — Publicly Traded — MetLife Spinoff (2017) — ~$230B Total Assets

Brighthouse was spun off from MetLife to isolate the legacy variable annuity and life insurance blocks — essentially, MetLife transferred its most complex, capital-intensive liabilities into a standalone entity. Brighthouse's RBC ratios are heavily influenced by its large derivatives portfolio used to hedge VA guarantees. The audit thesis: does the hedge program accurately offset the guaranteed minimum benefit exposure, and does Brighthouse's statutory surplus buffer adequately account for tail scenarios? Not PE-owned, but the balance sheet complexity and derivative concentration make it a critical case study in insurance solvency risk.

Planned
Regulatory & Market Context — March 2026
~30% Estimated share of U.S. life insurer general account now managed by PE-affiliated firms (up from ~5% in 2012)
NAIC C-1 Asset default risk charge — set in 1990s before private credit and PE-originated structured products dominated portfolios
$1T+ Global in-force annuity reserves reinsured to offshore affiliates (Bermuda, Cayman) — per IMF estimates
7 states Primary insurance domiciles for PE-owned platforms — Iowa, Indiana, Arizona, Texas, Delaware, Nebraska, Connecticut

The NAIC has acknowledged the rapid shift toward PE ownership in insurance and the systemic risk it creates. The NAIC's Private Equity Working Group, formed in 2021, has issued guidance on affiliated investment transactions and RBC calibration — but the framework remains reactive. State regulators lack the resources, cross-jurisdictional authority, and data access to fully assess the consolidated risk profile of a PE conglomerate that spans a dozen insurance subsidiaries, offshore reinsurers, and a multi-hundred-billion-dollar asset management platform.
