Hartford Takes $1.12B From Berkshire to End Its Asbestos Cover

Hartford settled its asbestos and environmental cover with Berkshire Hathaway's National Indemnity Company (NICO) at roughly 78 cents on the dollar. NICO paid $1.12 billion in cash on September 25 (Hartford 8-K, September 2026) against about $1.44 billion of recoverables Hartford was carrying, and the gain Hartford will report comes from releasing a deferred gain large enough to absorb that discount.

The commutation, signed September 23, ends an aggregate excess-of-loss treaty in force since December 31, 2016 and resolves a confidential arbitration. NICO began paying recoveries in the first quarter of 2026, then suspended further payment over a dispute Hartford has not described (Hartford Q2 2026 10-Q, July 2026), and a Hartford spokesman declined to discuss it (Business Insurance, September 2026). The asbestos reserves stay with Hartford, now without the reinsurer that had been funding their payout.

Key Takeaways

$317 million of recoverable was given up: the deferred gain stood at $814 million on June 30, the 8-K books a $497 million pre-tax gain, and the difference is the write-down of roughly $1.44 billion of recoverables to $1.12 billion of cash.
$423 million after tax was charged in the fourth quarter of 2016 to buy the cover; ending it adds $393 million to 2026 net income, because retroactive accounting front-loaded the cost and back-loaded the gain.
About 7% is the discount rate the $1.12 billion implies if NICO's obligation ran off at Hartford's 2025 net A&E paid pace of $190 million a year, against a 10-year Treasury at 5.11% on the signing date.
$108 million a year of deferred-gain amortization would have reached net income at that pace; it now lands in one quarter, while the A&E reviews that added $194 million, $203 million and $165 million in 2023 to 2025 continue.
$1.70 billion of run-off A&E reserves net of other reinsurance, NICO's share included, now run off against $1.12 billion of cash and a one-year net asbestos survival ratio of 9.2 years.

From a $1.5 Billion Limit to a $1.12 Billion Check

Hartford bought the cover in January 2017 for a $650 million premium, paid into a collateral trust, for up to $1.5 billion of adverse development above net A&E reserves of about $1.7 billion at year-end 2016 (Hartford announcement, January 2017). Retroactive accounting made the purchase expensive on day one: Hartford took a charge of about $423 million after tax in the fourth quarter of 2016. Annual reviews added $194 million to A&E reserves in 2023 and $203 million in 2024, and the $62 million ceded in 2024 used up the last of the limit (Hartford 2025 10-K, February 2026).

A full limit is a promise; cash moves only when paid losses cross the attachment. Hartford's cumulative A&E payments since 2016 passed the $1.7 billion attachment by the end of 2025, when it carried $1,436 million of unpaid recoverables and $64 million of paid recoverables against an $850 million deferred gain, the $1.5 billion ceded less the $650 million premium. GAAP releases that gain in proportion to cash collected. The $36 million Hartford amortized in the first quarter of 2026 is 4.2% of $850 million, consistent with collecting the $64 million. Then NICO stopped paying.

The two filings bracket the price. The deferred gain stood at $814 million on June 30, 2026 (Hartford Q2 2026 10-Q, July 2026), and the 8-K puts the commutation gain at $497 million before tax and $393 million after it (Reinsurance News, September 2026). So $317 million of the deferred gain was consumed writing the recoverable down to cash. That puts the balance extinguished near $1.44 billion, matching the year-end unpaid figure, and the price at 78% of it. After tax, the 2026 gain nearly mirrors the 2016 charge.

Pricing the Payout: What the $1.12 Billion Discounts

With the attachment behind it, NICO owed Hartford essentially every dollar of covered A&E paid loss until the limit ran out, so the recoverable behaved like an annuity whose term depends on Hartford's payout speed. Run-off A&E paid $190 million net of other reinsurance in 2025 and $169 million in 2024 (Hartford 2025 10-K, February 2026). The 10-year Treasury closed at 5.11% on September 23, the day the agreement was signed (Federal Reserve H.15 via FRED, September 2026).

The table discounts the $1.437 billion balance at three level payout speeds with mid-year timing. It uses run-off paid losses only and ignores the smaller A&E reserves Hartford carries in its ongoing segments, so it errs toward a slower payout and a lower present value.

Annual payout	Years to exhaust	Value at 5.11%	Rate that prices it at $1.12B
$170M (2024 pace)	8.5	$1.17B	6.3%
$190M (2025 pace)	7.6	$1.20B	7.1%
$210M (faster)	6.8	$1.22B	7.9%

At any of those speeds a Treasury-discounted price sits $50 million to $100 million above what NICO paid. That band is the visible cost of the arbitration and of holding a recoverable from a counterparty that had already stopped paying once. On NICO's side, $650 million taken in January 2017 against about $1.18 billion returned in 2026 works out to roughly 6.4% a year compounded on the premium it held for nearly a decade.

CNA's 2010 loss portfolio transfer with the same counterparty shows the alternative path. CNA paid a $2 billion premium for a $4 billion aggregate limit, and sixteen years later its deferred gain still amortizes through quarterly results, as the site's reading of CNA's Q2 2026 mass-tort charge traced. Hartford has converted the equivalent stream into one quarter of net income and fixed its reserve credit at a number.

The Amortization Cushion That Left With the Cash

Hartford's A&E reserves had been fully net of the cover since the limit ran out, so the 2025 review's $165 million charge already fell on earnings. The 10-K said plainly that "no remaining coverage is available for any future adverse net reserve development, which may be significant" (Hartford 2025 10-K, February 2026).

The commutation removes the offset. Each dollar NICO paid would have released about 57 cents of deferred gain, the $850 million gain over the $1.5 billion ceded. At the 2025 paid pace that is about $108 million a year of favorable prior-year development, close to 60% of the $187 million average A&E strengthening across 2023 to 2025. Core earnings never counted the amortization, so the loss of that offset shows in net income and book value.

The statutory balance sheet moves the other way. Under SSAP No. 62R a cedant carries retroactive cessions as a write-in contra-liability and holds the gain in special surplus (NAIC Casualty Actuarial and Statistical Task Force, December 2021), and Hartford's 10-K confirms its deferred gain sits in special surplus under statutory rules. That gain was already counted in statutory surplus. Swapping roughly $1.44 billion of contra-liability for $1.12 billion of cash therefore reduces surplus by about $317 million before tax, in the same transaction that adds $497 million to GAAP pre-tax income.

The cash also has to cover more than the recoverable did. Run-off A&E reserves stood at $1,703 million net of other reinsurance at year-end 2025, of which NICO was funding $1,436 million and Hartford $267 million. The full $1.7 billion now runs off against $1.12 billion of cash and its investment income, with a one-year net asbestos survival ratio of 9.2 years and three straight annual reviews that each added more than $160 million. The roughly $580 million gap, and every future strengthening, draws on the same statutory surplus the commutation just reduced.
