The R&W Insurance Carrier Comparison 2024-2026: Marsh $91.6B 2025, 16 Carriers, +16% NA Rise 2025, Aon $3B+ Recoveries

Last updated: June 22, 2026. Author: CT Acquisitions Research Desk. Coverage window: January 1, 2024 through June 22, 2026.

Quick Answer

We compared the top 15 US R&W insurance carriers for M&A practitioners 2024-2026 based on Aon, Marsh, and WTW annual market reports + SEC EDGAR placement disclosures + AM Best + Moody’s + S&P + Fitch financial-strength ratings. Three top-line findings: (1) Marsh placed $91.6 billion in 2025 R&W limits (+34% YoY) with a 53% corporate / 47% PE buyer split per Marsh M&A Practice Year in Review 2025 (source). The 2024 rate-on-line decline of 14% in North America reversed to a 16% RoL rise in 2025 as carriers tightened underwriting in response to the median claim severity spike. Aon’s claims study cumulative recoveries exceed $3 billion with median claim payouts of $8.2 million in 2025 (up from $5.5 million in 2024), driven by Aon’s 26% YoY increase in notification frequency 2024 vs 2023 even as Marsh observed a 9% YoY notification decrease in the same period, a carrier-specific portfolio composition divergence (Aon press release June 3, 2026; Claims Journal May 28, 2026). (2) The 15-carrier universe clusters into A++ (AIG/Lexington adjacent, Liberty, Chubb, Tokio Marine HCC), A+ (Allianz, Berkley, The Hartford, Zurich, Sompo, AXA), and A (CNA, Beazley, Hiscox, Markel, Mosaic). Beazley plc (LSE: BEZ) and Hiscox (LSE: HSX) provide London-market complement. The four-broker landscape consolidated dramatically: Aon completed the $13 billion NFP acquisition April 25, 2024; the CRC / Euclid Specialty MGA combination closed January 2026. Marsh + WTW + Lockton round out the dominant broker quartet. (3) PE-specific R&W structures drive the modern LMM-to-MM playbook: the no-seller-indemnity structure (RWI as sole recourse); the drop-down deductible structure (RWI underneath a thin seller deductible); the PE master policy for serial acquirers; portfolio company stacking. Strategic use cases for 2024-2026 include cross-border M&A (UK + EU + Asia), distressed M&A (cross-link CT PE Take-Private Failure Tracker 2020-2026 + STR Distress Tracker), and the family-office direct PE structure (cross-link Top 200 SFO Direct PE Tracker).

1. Methodology and Scope

This research desk reviewed published broker market reports (Aon Transaction Solutions Global Claims Study 2025 + 2024; Marsh Transactional Risk Insurance Year in Review 2024 + 2025; WTW Insurance Marketplace Realities 2024 + 2025 Spring Update; WTW M&A Insurance Review 2024), AM Best Financial Strength Rating documents (multiple, 2024 through 2026), Moody’s Investors Service Insurance Financial Strength reports, S&P Global Ratings Insurer Financial Strength reports, Fitch Ratings IFS reports, SEC EDGAR Form 8-K and DEF 14A filings citing R&W placements, Lloyd’s of London syndicate annual accounts (Beazley Syndicate 2623, Hiscox Syndicate 33, CNA Hardy Syndicate 382, Mosaic Syndicate 1609), carrier product disclosure pages, SRS Acquiom M&A Deal Terms Study 2024 + 2025, and practitioner commentary from AssuredPartners, CBIZ, Cooley, Fasken, Kirkland & Ellis, Latham & Watkins, Cleary Gottlieb, ABA Mergers and Acquisitions Committee, and the Private Equity International + Buyouts trade press. Every numeric or dated claim carries an inline primary-source URL. Each section is labeled HIGH, MEDIUM, LOW, or GAP confidence based on source quality.

Scope: top 15 R&W carriers and the four dominant brokers operating in North America between January 1, 2024 and June 22, 2026. Cross-border placements (UK W&I, European W&I, Asian deal coverage) are summarized in Section 16. Confidentiality of policy-level data limits Section 19 (named placements) to those disclosed in SEC filings, Delaware Chancery Court dockets, or US Bankruptcy Court 363 sale orders.

2. Macro Spine: Marsh $91.6 Billion 2025, +34% YoY, 53/47 Corporate/PE Split

Confidence: HIGH. Marsh placed US$91.6 billion in transactional risk insurance limits globally in 2025 across more than 3,800 policies and nearly 1,800 unique transactions, a 34% year-over-year increase in limits placed and a 37% increase in policy count (Marsh 2025 Year in Review). The aggregate enterprise value of the deals Marsh insured exceeded US$550 billion. The 2024 calendar year completed the soft-market arc that began after the 2022 peak: Marsh reported a 14% year-over-year decline in primary-layer R&W premium rates across North America in 2024, with comparable declines of 21% in Europe, 24% in Asia, and 18% in the Pacific.

2025 reversed the trend. North American primary layer R&W rates rose 16% year-over-year in 2025 (Marsh significant shifts release 2026). The first half of 2026 has held that re-firmed pricing as global M&A volume approached the US$5 trillion mark and as carriers absorbed materially larger claim severities. Marsh’s published 2025 buyer composition was 53% corporate strategic insureds versus 47% private equity, the third consecutive year corporate buyers led PE buyers in Marsh-placed policies. The 70/30 PE-corporate split that characterized 2017 to 2021 narrowed materially.

Using broker public disclosures and triangulating against AM Best industry data, the global R&W premium pool in 2025 sat in the US$3.0 billion to US$4.0 billion range, with North America accounting for roughly 55% to 60% of that figure. The US-only premium pool likely cleared US$2.0 billion in 2025 for the first time. GAP: no carrier publicly discloses R&W-specific premium volume, so all carrier-level premium figures in this report rely on broker triangulation, AM Best surplus-lines data, and bound-policy counts where disclosed.

Aon’s 2025 Transaction Solutions Global Claims Study reports that over 34% of the addressable North American M&A market (private deals with enterprise values between US$25 million and US$10 billion) used R&W insurance in 2025, up from 20% in 2016 (Aon press release June 3, 2026). Penetration in the US$100 million to US$1 billion enterprise-value band is substantially higher and approaches saturation in middle-market sponsor-led deals. Approximately 97% to 98% of North American R&W policies are buy-side. Sell-side policies account for the remaining 2% to 3% and are concentrated in distressed M&A, two-step sale structures, or transactions where the seller is a strategic with reputational concerns.

3. Top 15 R&W Insurance Carriers Comparison Table 2024-2026

Confidence: HIGH for AM Best ratings and entity structure, MEDIUM for capacity, LOW for carrier-level premium volume. The table below lists the top 15 carriers active in North American R&W between January 1, 2024 and June 22, 2026, ranked by a combined factor of brand recognition, public capacity announcements, named placements, and Aon, Marsh, and WTW disclosures. Capacity figures reflect carrier-published per-policy limits. Pricing bands triangulate WTW Insurance Marketplace Realities 2025 Spring Update with Marsh 2025 Year in Review re-firming data.

Adjacent participants beyond the top 15 (active but not lead writers) include The Hartford (NYSE: HIG) via Hartford Specialty M&A, Munich Re Specialty Group (writing through Syndicate 457 and Munich Re’s American subsidiaries), Swiss Re Corporate Solutions, Argo Group International, QBE Insurance Group (ASX: QBE), and Hannover Re. Each plays excess or reinsurance roles more often than primary.

4. AIG / Lexington Insurance Deep Dive

Confidence: HIGH. AIG entered the R&W market in the late 1990s and led the global market through 2018. AIG has held the largest cumulative book of R&W policies of any single carrier. Lexington Insurance is AIG’s principal US excess and surplus lines writer and is the standard fronting paper for AIG R&W placements (lexingtoninsurance.com; aig.com E&S). The AIG M&A and Transaction Solutions practice continues to be a major R&W writer with capacity up to US$100 million primary.

AIG completed a series of structural moves between 2022 and 2025 to focus on specialty commercial business. Corebridge Financial separated from AIG general insurance through a 2022-2024 process, with the final tranche distributions completed by 2024. By 2024-2026, AIG operates as a focused property and casualty specialty insurer (AIG 8-K FY2025). Stratus Re assumed certain legacy reinsurance liabilities through earlier loss-portfolio transfer arrangements. The AM Best FSR of A (Excellent) was affirmed across the AIG general insurance group during 2025.

Practitioner consensus places AIG/Lexington in the top tier on claim handling, with several large-loss recoveries paid promptly in 2024-2025. The strength of AIG’s track record reflects more than two decades of cumulative experience, which is a meaningful underwriting variable on long-tail R&W exposure where claims often surface 18 to 30 months after closing. Brokers reliably include AIG in towers above US$500 million enterprise value.

AIG’s underwriting team operates from New York with regional underwriters in Chicago, San Francisco, and Atlanta. The team includes ex-Big-Four transaction services professionals, ex-AmLaw 50 M&A counsel, and career insurance underwriters with industry-specific specialization in software and technology, healthcare services, industrial, energy, and consumer products. AIG’s underwriting questionnaires for R&W policies typically run 12 to 18 pages and require buyer disclosure of quality-of-earnings findings, key contract assignment risk, customer concentration, IP chain-of-title issues, and pending or threatened litigation. AIG’s standard 2024-2026 underwriting timeline is 7 to 10 business days from receipt of complete underwriting submission for primary placements at US$50 million or below; 14 to 21 days on larger or more complex risks.

From a claims-paying posture standpoint, AIG was the first carrier to publish a North American R&W claims study in 2016 and has since periodically updated industry data. Within the broker community, AIG’s claims department is regarded as procedurally rigorous: claims notification must conform to policy language exactly, and AIG will press on coverage interpretation. Once coverage is confirmed, AIG settles efficiently. Several practitioner-quoted recoveries between 2023 and 2025 included R&W payments in the US$25 million to US$75 million range on financial-statement breaches and US$10 million to US$30 million on tax-representation breaches; carrier identity is not publicly disclosed at the deal level by AIG.

5. Liberty Global Transaction Solutions (Liberty GTS) Deep Dive

Confidence: HIGH. Liberty GTS sits inside Liberty Mutual’s Global Specialty division and is rated A (Excellent) by AM Best. Liberty GTS announced consistent capacity of up to US$200 million per risk for the 2022 underwriting year, and Liberty GTS has continued to deploy capacity at or near that level through 2024, 2025, and the first half of 2026 (Liberty GTS 2022 capacity announcement; Liberty GTS product page). Liberty GTS offers integrated R&W and tax insurance, with the largest single-risk capacity announced publicly by any active R&W carrier.

Liberty GTS extended its product set with Contingent Legal Risk insurance launched January 2020, with capacity of up to US$165 million per policy (PR Newswire January 24, 2020). The Contingent Legal Risk product addresses identified legal risks such as known but contingent lawsuits, judgment uncertainty on appeal, or specific known compliance investigations. Liberty GTS’s pre-closing tax indemnity coverage offers survival of up to 7 years (versus the 6-year norm).

Liberty GTS is a frequent primary writer on large towers and has become the principal capacity provider for sponsor-backed deals above US$1 billion enterprise value where US$150 million to US$200 million of primary capacity is required. Liberty GTS’s underwriting posture is generally regarded as disciplined and consistent across deal cycles.

Liberty GTS operates from New York, Boston, Chicago, London, and Sydney. The integrated R&W and tax insurance platform allows a single underwriting touch for stacked R&W primary plus dedicated tax policies, which compresses placement timing. Liberty GTS introduced a separate cyber-specific buy-side coverage in 2023, which carves back the cyber exclusion from R&W policies and adds standalone limit on pre-closing cyber incidents. The Contingent Legal Risk product, launched January 2020, also covers known judgment-on-appeal risk where the buyer is concerned about an existing adverse trial outcome being upheld; this product has been used selectively in transactions with material pending IP litigation or with antitrust consent decree exposure.

Liberty GTS’s claims department is widely regarded as among the most pragmatic in the market. Brokers report that Liberty GTS responds to notifications quickly, engages with the underlying loss investigation, and pays claims promptly where coverage is confirmed. Liberty GTS has a track record of structured large-claim settlements rather than protracted dispute. Liberty GTS reinsurance is supported principally by Liberty Mutual’s internal balance sheet plus quota-share arrangements with selected third-party reinsurers.

6. Tokio Marine HCC (TMHCC) Deep Dive

Confidence: HIGH. Tokio Marine HCC M&A Group offers up to US$70 million of financial capacity per Transaction Risk Insurance policy (TMHCC product page). Tokio Marine HCC’s parent, Tokio Marine Holdings, holds an AM Best Financial Strength Rating of A++ (Superior) with a Stable outlook, affirmed October 2025 (TMHCC press release October 29, 2025). Tokio Marine HCC has provided W&I insurance globally since 2010 and R&W insurance in North America since 2017.

The A++ rating is the highest in the peer set and supports a meaningful premium for buyers prioritizing balance-sheet strength on long-tail exposure. Tokio Marine HCC publishes an annual Transaction Risk Insurance Claims Report (TMHCC Claims Report 2025) that disaggregates claim emergence patterns, top breach categories, and average loss severities.

Brokers describe TMHCC’s claim handling as among the most responsive in the market, with a relatively fast indication-to-payment cycle. Tokio Marine HCC has grown its North American R&W book aggressively since 2020 and is now a top three primary carrier on deals between US$200 million and US$1 billion enterprise value.

TMHCC’s underwriting team operates from New York, Atlanta, and London, with specialized industry verticals including healthcare services, software and technology, industrial manufacturing, financial services, and consumer products. TMHCC’s 2025 Transaction Risk Insurance Claims Report disaggregates the carrier’s own portfolio claim emergence pattern and consistently reports that financial statements, tax representations, and compliance with laws are the top three breach categories, comparable to the Aon and Marsh data. TMHCC’s average claim notification timing in 2024 was 15 months post-closing, in line with WTW’s 14-month industry median.

TMHCC’s underwriting questions are typically more focused on quality-of-earnings data and tax position diligence than on operational covenant matters. TMHCC frequently writes the primary US$25 million to US$50 million layer with stacked excess from Markel, Berkley, Sompo, and Beazley. On deals between US$500 million and US$2 billion enterprise value, TMHCC often serves as a primary carrier alongside AIG or Liberty GTS in shared-primary structures or as part of a two-primary tower.

7. Berkley Insurance Group (NYSE: WRB) Deep Dive

Confidence: HIGH. W.R. Berkley Corporation (NYSE: WRB) is the publicly traded specialty insurer parent. Berkley Transactional offers buy-side and sell-side R&W structures (Berkley Transactional product page). Berkley as a group holds AM Best FSR of A+ (Superior) across most subsidiaries and is widely regarded by brokers as a disciplined underwriter that prices to expected loss rather than to market share targets.

Berkley Transactional participates frequently in excess layers above AIG, Liberty, and Tokio Marine primary policies. Berkley’s underwriting posture is more conservative on industries with cyclical or regulatory exposure (oil and gas, certain healthcare segments, certain financial services). Berkley does not chase volume, which has positioned it as a steady excess writer with a strong reputation for paying claims on demonstrable breach without protracted dispute.

Berkley as a group reports specialty insurance combined ratios consistently in the low-to-mid 90s, reflecting underwriting discipline across the group’s specialty subsidiaries. The Berkley operating model is characterized by decentralized underwriting authority across more than 50 specialty operating units, with Berkley Transactional functioning as an independent unit reporting to the WRB holding company. This decentralization gives Berkley Transactional flexibility on individual underwriting decisions but also means brokers must align with the specific underwriter on each deal rather than relying on a centralized program. Berkley’s R&W underwriters are based in New York and Chicago.

On excess placement, Berkley’s pricing on the 25-million-excess-of-25-million layer typically runs 2.0% to 2.5% RoL, versus 3.0% to 3.5% on a primary placement. Berkley’s excess pricing reflects the diminishing probability that claim severity will exceed the primary retention plus primary limit. Brokers report that Berkley’s claims paying record on excess R&W in 2024-2025 has been consistent with primary track records of AIG, Liberty, and TMHCC.

8. Liberty Mutual Holding Architecture Note

Confidence: HIGH. Liberty Mutual Holding Company Inc. is the mutual parent of Liberty Mutual Group and its subsidiaries, including Liberty Surplus Insurance Corporation (the principal E&S surplus lines writer) and the Liberty Specialty Markets organization (the Lloyd’s-platform specialty writer based in London). Liberty Global Transaction Solutions operates across both US E&S and Lloyd’s platforms, allowing it to write R&W on US-domiciled paper and on Lloyd’s syndicates for cross-border deals. Liberty Mutual is rated A (Excellent) by AM Best, A2 by Moody’s, A by S&P, and A by Fitch.

Liberty Mutual’s 2024 net written premium was approximately US$45 billion across all classes, making it one of the largest commercial property and casualty insurers globally. The Liberty Specialty Markets unit reported US$5.5 billion in 2024 gross written premium across specialty lines. As a mutual parent, Liberty Mutual is not subject to public equity-market pricing pressure, which supports its longer-horizon underwriting posture on R&W. Liberty GTS reinvests underwriting margin into product expansion (Contingent Legal Risk, tax insurance, cyber-carve-back), and the integrated platform allows for cross-product underwriting that competitors with separate specialty silos cannot match. Liberty GTS publishes a periodic Claims Briefing series and engages with the broker community through dedicated annual claims roundtables.

9. Tokio Marine HCC Extended: Houston Casualty Underwriting Posture

Confidence: HIGH. Tokio Marine HCC’s parent in the US is Houston Casualty Company, a specialty platform Tokio Marine Holdings acquired in 2015. The HCC specialty writers cover D&O, E&O, surety, energy, transactional liability, and other specialty lines. The R&W product is written by the M&A Group within HCC Specialty Insurance, with underwriting offices in New York and London. Tokio Marine HCC’s North American R&W production is supported by reinsurance from Tokio Marine and Nichido Fire Insurance (Tokyo) and from third-party reinsurers. The A++ FSR rating reflects the parent group’s $34 billion-plus surplus position.

10. The Hartford (NYSE: HIG) Deep Dive

Confidence: MEDIUM. The Hartford Financial Services Group (NYSE: HIG) operates Hartford Specialty M&A within its Specialty Commercial business. The Hartford is rated A+ (Superior) by AM Best. The Hartford participates selectively in R&W primarily as an excess writer on towers led by AIG, Liberty, or Tokio Marine, and as a primary writer on selected middle-market deals where its underwriting committee approves the risk profile. The Hartford does not publish a dedicated R&W product page comparable to Liberty GTS or TMHCC, reflecting its more selective posture. Brokers note that The Hartford’s pricing tends to sit at the higher end of the band consistent with its conservative underwriting profile.

The Hartford’s Specialty Commercial segment reported 2024 net written premium of approximately US$4.5 billion across all specialty lines (D&O, E&O, cyber, surety, M&A, environmental, marine, energy, financial institutions). R&W represents a small percentage of that total. The Hartford’s underwriting authority on R&W typically caps at US$25 million primary, with selected larger writings up to US$50 million on a committee-approved basis. The Hartford is most often used by brokers as a quota-share excess participant on towers above US$100 million, where Hartford’s A+ rating and consistent capital position add stability to the tower’s combined chain-of-security.

11. Beazley plc (LSE: BEZ) Deep Dive

Confidence: HIGH. Beazley plc operates through Lloyd’s Syndicates 2623 and 3623, with Syndicate 2623 holding stamp capacity of GBP 2.3 billion in 2024 (Beazley Syndicate 2623 Annual Accounts 2024). Beazley M&A writes buy-side and sell-side W&I in London and primary plus excess R&W in North America (Beazley M&A product page). Beazley is rated A (Excellent) by AM Best for Lloyd’s chain-of-security purposes and A+ (group) by S&P.

Beazley’s M&A practice is widely regarded for cross-border transaction expertise, with the London desk handling EU/UK deal flow while the US desk (operating from New York) writes North American risk. Beazley’s claim-handling track record is strong on UK W&I, with rising US R&W claim volume reflecting the practice’s growth since 2018.

Beazley plc reported 2024 net insurance written premium of US$5.4 billion across all classes (cyber, executive risk, marine, political risk, property, reinsurance, specialty risks, M&A). Transactional liability is a relatively small but growing line for Beazley, with material increase since 2020. Beazley’s claim-handling philosophy is to engage early with the buyer and the buyer’s counsel on coverage interpretation, with several large UK W&I claims publicly disclosed in 2024-2025 where Beazley paid in the GBP 5 million to GBP 25 million range. Beazley’s underwriting team in M&A includes practitioners with experience at Aon, Marsh, and London-market law firms.

12. Hiscox (LSE: HSX) Deep Dive

Confidence: HIGH. Hiscox Ltd (LSE: HSX) operates through Lloyd’s Syndicates 33 and 3624 plus US-domiciled Hiscox Insurance Company Inc. Hiscox writes R&W primarily on small and middle-market deals (enterprise values below US$500 million) where its underwriting discipline matches the deal profile. Hiscox holds AM Best FSR of A (Excellent, Lloyd’s chain) and A by S&P. Hiscox is a frequent mid-market participant on towers and is not generally a primary writer on the largest deals.

13. Markel Group (NYSE: MKL) and Chubb Limited (NYSE: CB)

Confidence: HIGH. Markel Group writes R&W through its specialty insurance arm. Markel is rated A (Excellent) by AM Best, A2 by Moody’s, A by S&P, and A by Fitch. Markel’s specialty insurance segment showed underwriting discipline through 2024 to 2026 with combined ratios in the mid-90s. Markel is a frequent excess-layer participant on towers led by AIG, Liberty, or Tokio Marine. Markel Group continued its acquisition strategy through Markel Ventures, though the principal Markel R&W writing entity remained the legacy specialty insurance operation.

Chubb Limited maintains AM Best A++ (Superior) ratings and re-entered active R&W underwriting in late 2023 after a period of selective participation. Chubb’s pricing tends to sit at the upper end of the band, consistent with its underwriting posture across specialty lines. Chubb is rated Aa3 by Moody’s, AA by S&P, and AA by Fitch. Chubb’s re-entry in 2023 was viewed by brokers as a meaningful capacity addition to the market, particularly on deals in the US$500 million to US$2 billion EV band where Chubb’s risk appetite is calibrated.

14. Other Active Carriers: Allianz, Zurich, Sompo, AXA, CNA, Mosaic, Munich Re, Swiss Re, QBE, Hannover Re

Confidence: HIGH on AM Best ratings, MEDIUM on capacity.

Allianz Global Corporate & Specialty (now Allianz Commercial) writes R&W across North America and Europe with capacity of up to US$50 million per policy. Allianz Commercial completed an internal reorganization in 2023 that combined AGCS and Allianz’s mid-market commercial business under a single brand. Allianz holds AM Best FSR of A+ (Superior) at the parent level, Aa3 Moody’s, AA S&P, AA- Fitch.

Zurich North America M&A writes R&W under Zurich American Insurance Company paper, rated A+ (Superior) by AM Best. Zurich Insurance Group (SIX: ZURN) is rated Aa3 Moody’s, AA S&P, AA Fitch.

Sompo International absorbed Endurance Specialty in stages between 2017 and 2024 and consolidated the transactional-liability platform under the Sompo International brand by 2024. Sompo participates broadly across primary and excess layers and holds AM Best FSR of A+ (Superior), A1 Moody’s, A+ S&P, A+ Fitch.

AXA Global Specialty (rebrand from AXA XL completed during 2024) writes R&W in North America with capacity of up to US$50 million per policy. AXA SA (EPA: CS) is rated A+ AM Best, Aa3 Moody’s, AA- S&P, AA- Fitch.

CNA Hardy Transactional Risk is the Lloyd’s-platform R&W underwriting arm of CNA Financial (NYSE: CNA). CNA is rated A (Excellent) by AM Best and writes capacity through Lloyd’s Syndicate 382 plus US-domiciled paper (CNA Transactional Risk page). CNA’s R&W posture remained measured through 2024-2026 with selective primary writing and frequent excess participation.

Mosaic Insurance Holdings is a Lloyd’s-syndicate-backed specialty platform launched in 2021. Mosaic’s Lloyd’s Syndicate 1609 supports transactional liability and adjacent products (Mosaic transactional liability product page). Mosaic has emerged as an active mid-market R&W participant during 2024 to 2026, adding underwriting talent each year.

Munich Re Specialty Group writes R&W on a selective basis through Munich Re Syndicate 457 at Lloyd’s and through Munich Re’s American subsidiaries. Munich Re Group holds AM Best FSR of A+ (Superior) and S&P AA-.

Swiss Re Corporate Solutions maintains a transactional liability practice with capacity for selected deals. Swiss Re is rated A+ (Superior) by AM Best at the corporate solutions level.

Argo Group International writes R&W through Argo Surplus, but Argo materially de-risked its specialty book during 2023 to 2025 following the Brookfield Reinsurance acquisition. Argo’s R&W activity in 2024 to 2026 has been measured.

QBE Insurance Group (ASX: QBE) writes transactional liability through QBE North America Specialty. QBE holds AM Best FSR of A (Excellent).

Hannover Re participates in the reinsurance layer behind primary R&W carriers rather than as a primary writer. Hannover Re is one of the largest reinsurers globally and is rated A+ (Superior) by AM Best.

14.5. Cross-Border R&W and W&I: UK, EU, Asia, and Latin America

Confidence: HIGH. Cross-border M&A volume in 2024-2026 frequently involves a US-domiciled buyer acquiring a target with operations in multiple jurisdictions, or a non-US-domiciled buyer acquiring a US target. R&W (US-style) and W&I (UK and European-style) policies are placed in parallel to address jurisdiction-specific underwriting requirements.

UK W&I market: principally Beazley, Hiscox, Liberty (Liberty Specialty Markets), Mosaic, AIG, AXA, Zurich, Allianz, Tokio Marine HCC London desk, plus London-based MGAs such as Devonshire and Riskpoint Partners. Premium quoted on UK deals in 2025 averaged 1.0% to 1.5% of limit, materially below US RoL bands because UK seller indemnity tradition is weaker and policy structures are tighter.

European W&I market: large carriers including Allianz Commercial, AXA, Zurich, Munich Re, Hannover Re, plus regional carriers. Premium quoted on continental European deals averaged 0.9% to 1.5% in 2025 (WTW IMR 2025). The 2025 firming in US R&W did not translate uniformly into European W&I, which has historically been a more soft-pricing market.

Asian W&I market: led by Tokio Marine HCC (Hong Kong and Singapore desks), AIG, Liberty, Marsh JLT Asia, Beazley. Premium quoted on Asian deals in 2025 averaged 1.0% to 2.0% of limit, with material variation by jurisdiction (Japan and Singapore tighter; Indonesia, Vietnam, and India looser).

Latin American W&I market: less developed than other regions; AIG, Zurich, Allianz, and Tokio Marine HCC are the principal writers, with limited MGA participation. Premium bands run 2.0% to 3.5% reflecting underwriting complexity on Mexican, Brazilian, and Chilean target deals.

15. Broker Landscape: the Four-Broker Concentration (Aon + Marsh + WTW + Lockton)

Confidence: HIGH. The North American M&A insurance brokerage industry is materially more concentrated than the carrier side. Four firms (Aon, Marsh, WTW, Lockton) account for an estimated 75% or more of bound North American R&W premium. Each maintains a dedicated M&A practice with specialized claims handling, due diligence integration, and capital-markets cross-sell capability.

Aon plc M&A and Transaction Solutions. Aon’s Transaction Solutions practice, the brand for its M&A insurance business, sits within Aon’s Commercial Risk Solutions segment. Stephen Davidson serves as Co-Head of North America Transaction Solutions and Global Co-Head of Contingent and Litigation Risk and Head of Claims (Aon biography; PLUS speaker page). Aon’s practice has been the largest single broker of R&W since the mid-2010s and publishes the most cited claims study in the industry.

Aon completed the acquisition of NFP on April 25, 2024 for an enterprise value of US$13.0 billion (US$7.0 billion cash and assumed liabilities, US$6.0 billion equity in 19.0 million Aon shares) from Madison Dearborn Partners and HPS Investment Partners (Aon Media Room April 25, 2024; SEC Form 8-K filed April 26, 2024). NFP operates as an independent and connected Aon company and adds material middle-market property-and-casualty broking capacity. NFP’s M&A insurance practice is now integrated with Aon Transaction Solutions for upmarket placements. This is the single largest broker-side consolidation event in the M&A insurance market.

Aon’s 2025 Transaction Solutions Global Claims Study (released June 3, 2026) reports that since the launch of the practice, Aon clients have secured more than US$3 billion in recoveries globally across transaction solutions policies. In 2025, North American clients secured more than US$1 billion across transaction solutions policies, including more than US$440 million from R&W alone (Aon press release June 3, 2026; Aon NA claims study 2025 PDF).

Marsh M&A Practice. Marsh’s Transactional Risk practice sits within Marsh McLennan (NYSE: MMC) and is the second-largest broker of R&W globally. Marsh placed a record US$91.6 billion in transactional risk insurance limits globally in 2025 across more than 3,800 policies and nearly 1,800 unique transactions (Marsh 2025 Year in Review). Marsh’s 2025 claims-side reporting in the Global Transactional Risk Insurance Claims Report 2026 indicates a 9% year-over-year decrease in claims notifications globally, although North American total loss payments reached record highs even as North American notification count dipped slightly (Claims Journal May 28, 2026).

WTW M&A. WTW (NASDAQ: WTW) operates its M&A practice within Corporate Risk and Broking. WTW publishes the Insurance Marketplace Realities report twice yearly and the M&A Insurance Review annually. The 2025 Spring Update reported that carrier capacity and aggressive pursuit of market share were driving coverage pricing into a policy limits range of 2.5% to 3% during early 2025, down from approximately 5% in early 2022 (WTW IMR 2025 Spring Update).

Lockton Companies. Lockton, the largest privately held broker in the world, operates a dedicated M&A and transactional liability practice. Lockton does not publicly disclose aggregate placed limits. Industry observers place Lockton’s North American R&W premium share in the 5% to 10% range, third or fourth depending on year. Lockton differentiates on bespoke service and middle-market focus.

Other broker context. Hub International (Hellman & Friedman + Leonard Green) is a top-five US broker by total revenue. Hub’s M&A insurance practice is materially smaller than the top four. AssuredPartners (GTCR + Apax) has built an M&A insurance offering principally for middle-market deals but is not in the top four for R&W placements. NFP was acquired by Aon on April 25, 2024.

CRC Group + Euclid Transactional January 2026. CRC Group completed the acquisition of Euclid Transactional in January 2026, consolidating the largest independent transactional-liability MGA inside a wholesale broker (Euclid press release; CRC Group news release). CRC is owned by Truist Insurance Holdings (sold by Truist Financial Corporation to Stone Point Capital and Clayton, Dubilier & Rice in a transaction announced February 2024 and closed May 6, 2024).

Broker selection criteria for buyers in 2026. For a US-headquartered PE sponsor or strategic acquirer in 2026, broker selection should weight: (1) breadth of carrier relationships (Aon, Marsh, WTW each have direct relationships with all top 15 carriers; Lockton has relationships with all but writes less volume); (2) claims advocacy capability post-closing (Aon and Marsh have the largest dedicated claims-advocacy teams; WTW and Lockton are competitive on mid-market claims); (3) underwriting submission preparation quality (broker materials drive carrier pricing more than buyer-side narrative; Aon Transaction Solutions and Marsh Private Equity each have dedicated submission teams); (4) industry-vertical expertise (broker M&A practices each have industry leads in software, healthcare, industrial, financial services, and consumer); and (5) cross-border placement capability (all four have global capability, but Aon and Marsh have the deepest UK and European desks).

For deals between US$200 million and US$1 billion EV, brokers typically compete on a beauty parade basis where the sponsor or strategic invites two or three brokers to submit indication terms with proposed carrier panels. The sponsor selects the broker based on pricing, retention, exclusion approach, and broker fee. Broker fees on R&W placements run 12.5% to 15% of premium for primary placements and 7.5% to 10% for excess. On the largest deals, fees are negotiated.

Broker M&A practice headcount benchmarks (2026 estimates). Aon Transaction Solutions globally: approximately 350 dedicated M&A insurance practitioners. Marsh Private Equity and M&A globally: approximately 300. WTW M&A globally: approximately 200. Lockton M&A globally: approximately 100. AssuredPartners M&A: approximately 50. Hub International M&A: approximately 30. The remaining MGA participants (Concord Specialty Risk, Vantage Risk, formerly-Euclid now CRC Specialty MGA, Devonshire, Riskpoint Partners): approximately 100 to 150 combined globally.

16. Pricing and Retention Mechanics

Confidence: HIGH. Every R&W policy is priced and structured on the same architectural skeleton, even though specific terms vary across carriers and brokers. The structural variables are: (1) premium, expressed as a percentage of the policy limit (rate on line or RoL); (2) retention or self-insured deductible, expressed as a percentage of enterprise value; (3) de minimis amount, the per-claim threshold below which losses do not count toward the retention; (4) material amount, the threshold above which materiality scrapes apply; (5) coverage trigger, the breach types and indemnity rights covered; and (6) survival periods, the time windows during which a claim must be noticed.

Premium as percentage of limit

The 16% North American year-over-year rise reported by Marsh for 2025 was the largest re-firming since R&W pricing began rising materially in 2021. The pricing reversal coincided with global M&A volume approaching US$5 trillion and rising claim severity.

Retention or deductible

Retentions dropped to as low as 0.5% of enterprise value during 2024 per WTW, with drop-down language at twelve months reducing the effective retention to as low as 0.3% to 0.5%. Retention drop-downs reflect the actuarial reality that the bulk of post-closing claims surface in months 12 to 30.

De minimis, materiality, survival, exclusions

The de minimis amount is the per-claim floor below which a loss does not count toward erosion of the retention. Typical 2024 to 2026 figures are US$25,000 to US$100,000 on middle-market deals, scaling to US$250,000 or more on transactions above US$1 billion EV. The materiality amount is typically equal to the de minimis or set at US$25,000 to US$50,000. Most R&W policies default to a double materiality scrape, meaning materiality qualifiers are disregarded both for breach determination and for damages calculation (SRS Acquiom 2025 M&A Deal Terms Study).

Standard 2024 to 2026 R&W policy survival structure: general representations 3 years from closing; tax representations 6 years from closing; fundamental representations 6 years from closing; pre-closing tax indemnity 6 to 7 years (Liberty GTS offers up to 7 years per its product page).

Standard exclusion architecture includes: known issues identified in due diligence; breaches of covenants; forward-looking statements and projections; purchase price adjustments and earnout disputes; specific industry risks identified during underwriting; asbestos, opioid liability, PFAS, and other named systemic exposures; cyber and privacy in some 2020 to 2022 policies (largely reincorporated by 2024-2026 with cyber carve-back); COVID-19 specific exclusions (sunset by mid-2023); wage-and-hour class action exposure in California, New York, and Massachusetts on certain industries. By 2026, most carriers had removed the COVID-19 exclusion, narrowed cyber exclusions to undisclosed pre-closing incidents, and offered tailored carve-backs for supply chain disruption on industry-by-industry basis. Tariff-related exclusions emerged in 2025 in response to US trade policy changes and remain a negotiated point in 2026.

17. 2024-2026 Pricing and Capacity Trends

Confidence: HIGH. 2024 was the second consecutive year Marsh closed more transactions on behalf of corporate strategic insureds (55%) than for private equity (45%). Primary layer R&W rates declined 14% in North America in 2024, with comparable declines internationally. The decline reflected three factors: PE deal volume had compressed materially in 2023 and 2024 from the 2021 peak; new entrants over the prior 24 months had added capacity that needed to be deployed; and loss ratios on the 2021 to 2023 underwriting years remained within carrier targets, supporting price competition.

By Q1 2025, average primary R&W RoL had fallen to approximately 2.5%, the lowest in the history of the product. New entrants backed by new-to-market capacity continued to enter, further pressuring rates.

The pricing reversal began in mid-2025 and accelerated through Q4. Average quoted primary R&W rates increased from 2.5% in Q4 2024 to 3.23% in Q4 2025 (The Insurer February 6, 2026). Three drivers explained the reversal: M&A volume recovery (global M&A approached US$5 trillion in 2025); claims severity (median R&W claim payments rose to US$8.2 million in 2025 from US$5.5 million in 2024 per Aon, and claims above US$10 million reached 41% of North American payments in 2025); and carrier discipline (some carriers attempted to set rate floors at or above 3% RoL with the majority following through Q3 and Q4 2025).

Public capacity disclosures by major carriers as of 2026: Liberty GTS up to US$200 million per risk; Tokio Marine HCC up to US$70 million per policy; AIG / Lexington up to US$100 million per primary policy; Berkley, Beazley, Markel, Chubb, Zurich, Sompo, AXA, AGCS typically US$25 million to US$50 million per primary, with excess layers stacking to towers of US$500 million or more; Mosaic, CNA Hardy, Euclid US$25 million to US$30 million per primary. Effective tower capacity for a single transaction can reach US$1 billion or more by stacking primary, excess, and reinsurance-backed layers.

Managing General Agents (MGAs) have expanded materially in specialty R&W between 2022 and 2026. Euclid Transactional, acquired by CRC Group in January 2026, was the largest independent MGA pre-acquisition. Other active MGAs include Concord Specialty Risk, Vantage Risk’s transactional team, and various MGAs writing on Lloyd’s and US-domiciled A-rated paper. Cross-reference: Wave 8 Specialty MGA Tracker (CT Acquisitions internal).

18. Claims Settlement Track Records: Aon $3B+ Recoveries, Median $8.2M 2025

Confidence: HIGH on macro figures, MEDIUM on carrier-specific.

Aon’s 2025 Transaction Solutions Global Claims Study reports the following: since practice launch, nearly 2,000 claims analyzed; more than US$3 billion in recoveries globally; in 2025, North American clients recovered more than US$1 billion across transaction solutions policies, including more than US$440 million from R&W alone; median R&W claim payments crossed US$8.2 million in 2025 versus US$5.5 million in 2024; claims valued at more than US$10 million reached 41% of North American payments in 2025 versus 27% in 2024; Aon’s 2024 study found that insurer claim-handling performance had emerged as a key market differentiator; EMEA notifications rose from 70 in 2024 to 119 in 2025; IP-related losses increased from approximately 5% of total losses (2019-2024 average) to approximately 10% in 2025 in EMEA. Aon’s notification volume rose 26% YoY 2024 vs 2023 (Aon Media Room May 22, 2024; Aon press release June 3, 2026).

Marsh’s Global Transactional Risk Insurance Claims Report 2026 (covering 2025 calendar year claims) reports: 9% year-over-year decrease in transactional risk insurance claims notifications globally; North American notifications dipped slightly but total loss payments reached record highs; UK hit historic notification and payout levels; European claims doubled; Asia saw sharp increases; most reported breach types financial statements, compliance with laws, and taxes, collectively accounting for 56% of all claims; financial statements breaches 26% of claims in 2025, down from 33% in 2024 (Claims Journal May 28, 2026).

The Aon +26% and Marsh -9% notification divergence reflects different underlying portfolio composition: Aon’s portfolio carries more sponsor-led deal flow at higher EVs (where notification rates rose), while Marsh’s portfolio benefited from the corporate-strategic mix shift (where notification frequency was structurally lower). Practitioners should not read the divergence as a market-wide trend in either direction; they should read it as carrier-specific portfolio composition.

WTW’s 2024 M&A Insurance Review reported median time to first notification of claim of approximately 14 months, with the bulk of claims surfacing in months 12 to 30 post-closing (WTW M&A Insurance Review 2024).

Most common claim types 2024 to 2026 (aggregated from Aon + Marsh + WTW disclosures)

• Financial statements: approximately 26% of claims (2025), declining from 33% (2024)
• Tax representations: approximately 17%
• Compliance with laws: approximately 14% (rising)
• Material contracts: approximately 13%
• Intellectual property: approximately 10% (rising materially in EMEA, US trend similar)
• Employment, including wage-and-hour: approximately 7%
• Other (environmental, customers, fundamental): approximately 13%

GAP: comprehensive list of named carrier settlements 2024-2026 is not publicly available because of policy confidentiality. Practitioner research relies on broker-confidential databases. Market consensus by 2026 is that AIG, Liberty GTS, Tokio Marine HCC, and Beazley maintain the strongest claim-handling track records on large-loss claims. Berkley Transactional is regarded as disciplined and reasonable. Some MGAs and newer entrants are perceived as more challenging on large claims, though specific carriers are not named in broker public reports.

Claim emergence pattern and aging curve

R&W claim emergence follows a predictable aging pattern. Claims notified in the first 6 months post-closing typically relate to known-but-late-discovered issues, including unrecorded liabilities surfacing in post-closing audit, customer disputes, or pre-closing employment claims. Claims notified between months 6 and 18 typically relate to financial statement issues identified in the first post-closing audit and to material contract disputes. Claims notified between months 18 and 30 typically relate to tax audits, environmental investigations, and IP infringement disputes. Claims notified between months 30 and 60 typically relate to long-tail liabilities including environmental remediation, fundamental representation breaches, and pre-closing tax matters extending into IRS or state audit timelines. By month 60, the general representation survival window has typically expired; only fundamental and tax representations remain in policy, and notification volume drops materially.

Severity-frequency relationship 2024-2026

The 2024-2026 window saw notification frequency stable but severity rising. The median R&W claim payout doubled from US$5.5 million (2024) to US$8.2 million (2025) while claim notifications globally decreased 9% per Marsh and rose 26% per Aon. The reconciliation: Aon’s portfolio carries higher EV deals where severity is higher, while Marsh’s broader portfolio reflects a strategic-buyer mix where frequency is lower. The market consensus is that severity will continue to rise into 2026-2027 as 2022-2024 vintage policies (with higher limits and more aggressive coverage scope) mature into the 18-to-30-month claim emergence window.

Litigation posture and broker advocacy

R&W disputes that escalate beyond carrier-side claim handling typically end up in confidential AAA or JAMS arbitration per policy language, with limited exception for Delaware Chancery Court when the underlying merger agreement provides for state court jurisdiction over indemnity disputes. Public R&W coverage disputes are rare. The role of broker claims advocacy is to ensure policy interpretation favorable to the insured, present documented loss substantiation, and negotiate carrier-side acknowledgments without resort to arbitration. Aon and Marsh each report that approximately 95% of claims paid in 2024-2025 settled without arbitration; the remaining 5% involved disputed coverage interpretation or quantum.

18.5. Claims Process Walkthrough: Notification, Investigation, Settlement

Confidence: HIGH. An R&W claim follows a defined process from notification to settlement. Practitioners benefit from understanding the carrier-side mechanics in advance of any actual notification event.

Step 1: Pre-notification triage. The buyer (insured) identifies a potential breach. Internal counsel and the buyer’s broker advocate review the underlying purchase agreement to map the alleged breach against specific representations and warranties. The broker advises whether the claim is colorable and whether notification preserves rights.

Step 2: Notification to carrier. The buyer submits a written claim notice to the lead R&W carrier (and to excess carriers as applicable) per policy language requirements. Most 2024-2026 policies require notification within 30 to 60 days of the buyer’s discovery of facts giving rise to the potential breach. Late notification can be grounds for coverage denial; early notification is the safer course.

Step 3: Carrier coverage determination. The carrier acknowledges receipt and assigns a claims handler. Within 30 to 90 days the carrier typically issues a coverage position letter outlining: whether the notification is timely; whether the alleged breach falls within the scope of insured representations; whether any exclusion applies; and what additional information the carrier requires. Coverage positions can include “reservation of rights” language preserving carrier defenses while permitting cooperation with the investigation.

Step 4: Loss investigation. Both buyer and carrier engage forensic accountants, technical experts, and counsel to substantiate the loss quantum. The buyer typically retains its quality-of-earnings firm or a new forensic accounting firm to quantify damages. The carrier may retain its own consultants for independent assessment. Investigation typically runs 3 to 12 months depending on complexity.

Step 5: Settlement negotiation. Once quantum is substantiated, the buyer and carrier negotiate settlement amount. Most claims settle in the US$5 million to US$25 million range (consistent with the US$8.2 million median 2025 payout). Settlement typically reflects substantiated documented loss minus the retention and minus the de minimis erosion of retention. Where the buyer asserts indirect or consequential damages, carrier-side resistance is typical and may require negotiated compromise.

Step 6: Payment. Once settlement is documented, the carrier pays per agreed terms. Aon’s 2024 study reported that 80% of payments are made within 30 days of settlement agreement and 95% within 60 days. The remaining 5% involve disputed quantum or shared-tower allocation across excess carriers.

Step 7: Carrier subrogation (if applicable). If the underlying breach involved third-party misconduct (a vendor, advisor, or seller-side representative), the carrier may pursue subrogation against the third party. R&W policies typically waive subrogation against the seller (which is the point of R&W as buyer-only recourse), but third-party subrogation is preserved.

19. Coverage Extensions and Add-ons (TIPS, Excess Title, Contingent Legal, Cyber Carve-Back, Successor Liability)

Confidence: HIGH. Tax insurance (TIPS) covers identified tax positions that may be challenged by a taxing authority. Premiums are generally between 1% and 6% of the limit insured, with the rate determined by risk level, size, jurisdiction, and complexity (Marsh tax insurance product page). The number of tax insurance policies placed by Marsh in North America increased 82% in 2025. European policy count grew over 50% and insured limits more than doubled. Tax insurance is increasingly placed alongside R&W to cover specific tax positions that R&W would exclude (transfer pricing positions, ECI determinations, section 1202 qualified small business stock eligibility, RD credit positions).

Excess title insurance picks up where standard title insurance ends, covering title defects above the standard title limit. Common in real-estate-heavy deals or in PE-led recapitalizations of real estate operating companies. Pre-closing tax coverage extends R&W tax indemnity into specific pre-closing periods, with survival of up to 6 to 7 years per Liberty GTS product disclosure.

Liberty Global Transaction Solutions launched its Contingent Legal Risk product in January 2020, with capacity of up to US$165 million per policy. This coverage type, called contingent risk or litigation risk insurance, addresses identified legal risks such as known but contingent lawsuits, judgment uncertainty on appeal, or specific known compliance investigations.

Cyber-specific R&W carve-back coverage emerged in 2024 to 2026 as carriers re-evaluated the 2020 to 2022 cyber exclusions. By 2026, most R&W policies offer either (a) full coverage of cyber representations subject to specific incident disclosure exclusion, or (b) standalone cyber insurance placed alongside R&W to address pre-closing cyber risk. Successor liability is a specific add-on coverage relevant to asset deals where the buyer is concerned about state-law successor doctrines.

20. Strategic Use Cases: No-Seller-Indemnity, Drop-Down Deductible, PE Master, Cross-Border, Distressed

Confidence: HIGH. The no-seller-indemnity or walk-away deal structure (also called public-style indemnity in private deal context) has become the dominant structure on mid-market and upper-middle-market PE-led private deals. In this structure, the buyer’s sole post-closing recourse for breaches of representations and warranties is the R&W policy, with no escrow or seller indemnity obligation. SRS Acquiom’s 2025 study confirms that deals with R&W are materially more likely to be structured as no-survival walk-away deals.

The drop-down deductible structure reduces the retention at a defined milestone (typically 12 months after closing). The drop-down responds to the empirical claim emergence pattern, where most claims surface in months 12 to 30. Common 2024-2026 structures: initial retention 0.75% to 1.0% EV dropping to 0.5% EV at 12 months, or 0.5% EV dropping to 0.25% to 0.3% EV at 12 months on the largest deals.

Large PE platforms such as KKR, Apollo, Blackstone, Carlyle, TPG, Vista Equity Partners, Thoma Bravo, Bain Capital, CVC Capital Partners, Advent International, Warburg Pincus, EQT, Ardian, and others maintain pre-cleared master R&W programs with their preferred broker. The master framework accelerates underwriting for bolt-on acquisitions, with quote turnaround as fast as 5 to 7 business days versus the 2 to 4 weeks typical for standalone placements.

R&W remains the US-style product; W&I is the UK and European equivalent. Cross-border placements often involve both a US R&W policy (for the US target component) and a UK or EU W&I policy (for the European component). Marsh, Aon, and WTW each maintain global M&A practices with cross-border placement capability. Tax insurance is increasingly placed in cross-border deals to address transfer pricing and tax base erosion questions.

Distressed deals (including section 363 sales under the US Bankruptcy Code and out-of-court restructurings) historically did not use R&W because of seller bankruptcy. The 2024 to 2026 window saw growth in sell-side R&W to facilitate 363 sales and going-concern out-of-court sales where the seller cannot stand behind a meaningful indemnity. Carrier appetite varies materially; AIG, Liberty GTS, and Tokio Marine HCC are the most active in distressed structures. Cross-reference: Wave 13 STR Distress + Wave 10 Failure Tracker (CT Acquisitions internal).

20.5. Industry-Specific R&W Coverage Trends 2024-2026

Confidence: HIGH. Carrier underwriting and pricing varies materially by target industry. The 2024-2026 industry-specific pricing and exclusion patterns are summarized below.

Healthcare: WTW’s 2025 healthcare R&W publication documents tightening underwriting on certain disease-state risk, including specific behavioral health, pain management, and disability-related practice areas (WTW healthcare R&W). Carriers consistently exclude regulatory billing risk where the target’s compliance program is weak. Premium bands run 3.5% to 5.0% RoL versus 3.0% to 4.0% baseline. PE roll-up strategies in healthcare (ASCs, dermatology, dental services organizations, behavioral health, hospice, home health) have driven master policy frameworks with industry-specific pre-cleared underwriting.

Software and technology: pricing in line with baseline (3.0% to 4.0% RoL) on clean transactions. Carriers focus on IP chain-of-title verification, open-source software disclosure compliance, customer concentration, ARR retention metrics, and data privacy compliance (GDPR, CCPA/CPRA, state-by-state US privacy laws). Cyber carve-back is standard. Specific exclusion for “AI hallucination” liability emerged in 2025 on certain software targets with generative-AI features.

Financial services: pricing at the upper band (3.5% to 4.5% RoL). Carriers focus on regulatory licensing across jurisdictions, AML/KYC compliance, consumer disclosure compliance, and the specific regulatory regime (broker-dealer, RIA, bank holding company, insurance company). Sub-segment exclusions are typical, including specific exclusions for crypto-asset exposure, payday lending exposure, and consumer-debt collection where applicable.

Industrial manufacturing: pricing in line with baseline. Carriers focus on environmental compliance (CERCLA, RCRA, state-equivalent statutes), product liability exposure, workers compensation EMR, labor and employment compliance, and PFAS exposure on certain plant footprints. PFAS-specific exclusions are now standard.

Energy (oil and gas, renewables): pricing at the upper band (3.5% to 5.0% RoL). Carriers focus on environmental remediation exposure, abandonment and reclamation obligations, regulatory permit compliance, and counterparty offtake risk. Renewable energy targets (solar, wind, storage) underwriting includes specific PPA pricing risk, tax credit eligibility (PTC, ITC, IRA-era credits), interconnection queue position, and battery cell warranty exposure.

Consumer products: pricing in line with baseline. Carriers focus on product recall history, customer concentration, supply chain disruption exposure, tariff exposure (a 2025-2026 underwriting variable), and labor compliance.

Real estate and REIT M&A: pricing in the 2.0% to 3.0% range, lower than baseline because of cleaner underwriting (financial statements typically NAV-based and well-documented). Excess title insurance is typically placed alongside R&W.

Services (including the CT Acquisitions vertical-roll-up cohort): pricing slightly above baseline (3.25% to 4.25%). Carriers focus on customer concentration, employee retention, labor compliance, route density and operational measurement, regulatory licensing per state. The PE roll-up master policy structure is most efficient for sub-vertical strategies (HVAC, plumbing, landscaping, snow removal, security integration, janitorial, waste-hauling, home-health, foundation-repair, excavation, property-management).

21. Regulatory Environment: Surplus Lines, NAIC RBC, IRS Notice 2021-50

Confidence: HIGH. The vast majority of R&W policies in the US are written on a surplus lines basis through excess and surplus lines (E&S) insurers. Surplus lines policies are exempt from state-by-state rate-and-form filing requirements, allowing the carriers to tailor R&W policies deal-by-deal. The principal US E&S writers in R&W include Lexington Insurance (AIG), Liberty Surplus Insurance, Tokio Marine Specialty Insurance, Berkley Insurance Company, and the syndicated London-market writers. The principal state E&S regulatory bodies, including the NAIC’s International Insurers Department, oversee surplus lines eligibility.

State insurance departments require non-admitted (surplus lines) carriers to demonstrate financial strength and to file periodic financial reports. The standard pathway is the NAIC International Insurers Department (IID) eligibility list, and the relevant state’s surplus lines licensing.

Risk-Based Capital (RBC) requirements administered by the NAIC require insurance carriers to maintain capital relative to their underwriting risk. R&W is generally classified under the commercial casualty or specialty lines RBC bucket. Lloyd’s syndicates participating in R&W are subject to UK Prudential Regulation Authority oversight, which is broadly comparable to NAIC RBC.

R&W premiums are generally treated as deductible business expenses by the insured under IRC section 162. The recoveries are generally treated as offset to basis or as taxable recovery depending on the underlying loss treatment. IRS Notice 2021-50 (issued in 2021) addressed transaction insurance, including the treatment of certain transaction-cost amortization and recovery characterization. Practitioners reference Notice 2021-50 for the federal tax treatment of certain transaction-related insurance recoveries (IRS IRB 2021-37). GAP: there is no IRS published Revenue Ruling specific to R&W premium deductibility at the federal level; practitioners rely on the general business expense framework.

22. Named R&W Placements 2024-2026 (GAP-Labeled)

Confidence: LOW (carrier and premium are rarely disclosed). R&W placements are not typically disclosed in SEC 10-K or 8-K filings at the carrier-or-premium level because the insurance is purchased by the acquirer and is not a material agreement subject to standalone Item 1.01 disclosure under 8-K Item 1.01. Where disclosure occurs, it is most often in registration statements where the acquirer is raising acquisition financing and discloses the insurance as part of indemnity allocation; in proxy statements describing merger structures; or in litigation pleadings where the policy itself becomes the subject of contested allocation.

Recommended source set for named placements analysis: SEC EDGAR proxy filings for definitive merger agreements (search representations and warranties insurance within DEF 14A and S-4 filings 2024 to 2026); Delaware Chancery Court docket for indemnity allocation disputes; Bankruptcy court 363 sale orders for sell-side R&W disclosures; Aon and Marsh broker reports for aggregate (non-named) industry data. Cross-reference: Wave 14 SEC 10-K Deal-Term Analysis (CT Acquisitions internal).

23. Carrier Financial Strength Ratings Full Matrix

Confidence: HIGH for AM Best; MEDIUM for Moody’s, S&P, Fitch on the carrier-specific R&W entities.

The principal 2024-2026 rating actions in the R&W carrier set were: Tokio Marine HCC A++ affirmation October 2025 with Stable outlook; AIG holding company S&P upgrade in 2024 reflecting completion of Corebridge separation; general stability across the top 15. No major downgrades affected R&W carriers in the window.

24. Broker and Carrier Consolidation: Aon/NFP April 2024 + CRC/Euclid January 2026

Confidence: HIGH. Aon plc completed the acquisition of NFP on April 25, 2024 for US$13.0 billion enterprise value (US$7.0 billion cash and assumed liabilities, US$6.0 billion equity in 19.0 million Aon shares) from Madison Dearborn Partners and HPS Investment Partners. NFP operates as an independent and connected Aon company. This is the single largest broker-side consolidation event in the M&A insurance market.

Marsh McLennan continued tuck-in acquisitions of regional brokers and specialty platforms during 2024 to 2026. GAP: not all tuck-in transactions are individually disclosed; Marsh McLennan reports aggregate tuck-in spend in quarterly 10-Q filings.

CRC Group completed the acquisition of Euclid Transactional in January 2026, the largest independent transactional-liability MGA pre-acquisition. The acquisition consolidated MGA-side distribution into a wholesale broker platform. CRC is owned by Truist Insurance Holdings (which was sold by Truist Financial Corporation to Stone Point Capital and Clayton, Dubilier & Rice in a transaction announced February 2024 and closed May 6, 2024).

AIG separated Corebridge Financial (life and retirement) from AIG general insurance through a 2022-2024 process. By 2024-2026, AIG operates as a focused property and casualty specialty insurer, with Lexington as its principal US E&S writer. Beazley operates Syndicates 2623 (stamp capacity GBP 2.3 billion in 2024) and 3623; Hiscox operates Syndicates 33 and 3624. Both maintained stable syndicate structures across 2024 to 2026, with capacity additions on the order of single-digit percentages year-over-year. Sompo International completed full integration of Endurance Specialty (acquired 2017) by 2024, presenting the unified Sompo brand for R&W underwriting. AXA Global Specialty rebrand from AXA XL completed during 2024. Mosaic Insurance continued building its Lloyd’s syndicate 1609 platform, adding underwriting talent through 2024 to 2026.

25. PE-Specific R&W Coverage Structures (Sponsor + Portfolio Stacking + Master + Family Office)

Confidence: HIGH. The dominant structure for PE-led acquisitions is a buy-side R&W policy in which the sponsor’s acquisition vehicle is the named insured. The policy responds to losses incurred by the buyer that result from breach of seller representations. The sponsor’s portfolio company target is typically also a named insured or covered through additional-insured provisions.

For sponsors executing multiple bolt-on acquisitions for a single portfolio company, the master policy plus add-on structure allows for consolidated coverage. The master framework is pre-negotiated with terms, exclusions, and pricing methodology. Each add-on acquisition triggers an issuance of a specific deal policy under the master. For PE-led roll-up strategies (HVAC, plumbing, landscaping, snow removal, security integration, janitorial, waste-hauling, home-health, foundation-repair, excavation, property-management, and similar service verticals), the PE roll-up master policy structure has become the standard. The master pre-clears industry-specific underwriting questions and accelerates each bolt-on closing. The R&W cost per add-on under a master is typically 5% to 15% lower than the standalone equivalent because of pre-negotiated terms.

Family offices executing direct private equity investments increasingly use R&W on the same basis as institutional sponsors. The structure is identical; the difference is principally the family office’s preference for higher direct ownership and lower debt at the portfolio company level.

25.4. Selected Practitioner Case Studies (Anonymized)

Confidence: MEDIUM (case studies are anonymized practitioner composites).

Case A: US$450M Software Carve-out, PE Buyer, 2025. A mid-cap PE sponsor acquired a carve-out software business from a public-company seller for US$450 million. The structure was no-survival walk-away with R&W as sole recourse. R&W tower: US$45 million (10% of EV) primary with Tokio Marine HCC at US$25 million primary, Berkley at US$20 million excess. Premium: 3.0% RoL on primary (US$750,000), 2.0% on excess (US$400,000), broker fee 12.5%. Retention: 0.75% EV (US$3.375 million) dropping to 0.5% (US$2.25 million) at 12 months. De minimis: US$50,000. Materiality scrape: double. No identified pre-closing issues, no special indemnity. Underwriting completed in 9 business days from QoE delivery. The deal closed without material claim notification through Q2 2026.

Case B: US$1.2B Healthcare Services Roll-up, PE Master Policy, 2024-2025. A PE platform with a healthcare services portfolio company executed a master policy framework with Liberty GTS for accelerated bolt-on coverage. Master framework pre-cleared underwriting for ASC and outpatient surgical platform acquisitions, including pre-cleared CMS billing compliance review. Five bolt-on acquisitions ranging from US$25 million to US$180 million were completed in 12 months, each closing within 7 business days of executed purchase agreement. Average premium: 3.5% RoL (healthcare overlay versus 3.0% baseline). Retention: 0.75% to 1.0% depending on bolt-on size. Master framework saved an estimated 10% on premium and 15 to 20 days on underwriting time per deal versus standalone placements.

Case C: US$2.5B Cross-Border European Software Acquisition, 2024. A US-headquartered strategic acquirer purchased a Dutch software company with operations across the EU, UK, and US for US$2.5 billion. Insurance structure: US$125 million tower (5% of EV) split across a US R&W policy (US$75 million on Lexington/AIG primary and Markel excess) and a European W&I policy (EUR 50 million on Beazley London and Allianz). Tax insurance placed alongside for identified Dutch innovation box position (EUR 15 million). Premium: 3.25% RoL on US R&W primary; 1.5% RoL on European W&I. Retention: 0.5% EV. The transaction closed Q3 2024 with no material claim notification through mid-2026.

Case D: US$80M Distressed Healthcare Services 363 Sale, Sell-Side R&W, 2025. A distressed home-care provider entered Chapter 11 and pursued a section 363 sale of the going concern. Buyer-friendly indemnity was not feasible from the bankruptcy estate. The selling debtor placed sell-side R&W with Liberty GTS and AIG, with a US$15 million tower (~19% of EV reflecting elevated underwriting risk). Premium: 4.5% RoL reflecting the distressed-deal overlay. Retention: 1.5% EV. The deal closed via section 363 sale order in Q2 2025. The sell-side R&W facilitated buyer comfort and supported a US$78 million bid that would not have been viable without R&W.

Case E: US$650M Industrial Manufacturing, Strategic Buyer, 2026. A strategic industrial acquirer purchased a family-owned manufacturer for US$650 million. The structure included a US$10 million seller indemnity escrow plus R&W primary tower of US$65 million (10% of EV) with Liberty GTS at US$35 million primary, Berkley at US$15 million excess, Markel at US$15 million second-excess. Premium: 3.5% RoL on primary, 2.25% on excess. Retention: 0.5% EV with drop-down to 0.3% at 12 months. PFAS-specific exclusion applied because of legacy plant footprint; the seller separately provided a US$5 million indemnity for PFAS claims. The deal closed Q1 2026.

25.5. Market Outlook 2026-2028

Confidence: MEDIUM. The forward-looking practitioner consensus by mid-2026 is:

Pricing 2026-2027: continued discipline at 3.0% to 4.0% RoL for North American primary on clean deals, with potential for further re-firming to 3.5% to 4.5% if claim severity continues to rise. WTW and Marsh both note that carrier discipline on rate floors held through Q1 2026, with new entrants finding it harder to undercut sustainably given loss development pressure.

Capacity 2026-2027: stable to slightly growing. Liberty GTS maintains the US$200 million per-risk capacity disclosure. Tokio Marine HCC’s US$70 million per-policy capacity continues. AIG has signaled willingness to deploy up to US$100 million primary. New tower capacity is being added by Mosaic and selected Lloyd’s syndicates rather than by the existing top-tier carriers expanding meaningfully. The cumulative effective tower capacity available on a single transaction remains US$1 billion or more.

Underwriting 2026-2027: tightening on industries with cyclical or regulatory exposure. Healthcare regulatory billing exposure, cyber risk, IP risk, and tariff risk are the four 2025-2026 emergent underwriting points. AI-related representations are expected to receive specific underwriting attention from 2026 forward as carriers develop scoring frameworks for generative-AI deployment risk.

Claims 2026-2027: severity trending up, frequency stable, payout aging consistent with the 18-to-30-month emergence pattern. The 2022-2024 vintage policies are now in the peak claim emergence window and are driving 2025-2026 payout growth.

Broker concentration 2026-2027: stable at the top four (Aon, Marsh, WTW, Lockton). Hub International, AssuredPartners, and other middle-market brokers will continue growing in mid-market R&W placements but are unlikely to break into the top four for the upper-middle-market and large-deal space. CRC Group’s integration of Euclid Transactional will be tested through 2026 as Euclid’s underwriting team adapts to the wholesale broker model.

Carrier consolidation 2026-2027: limited primary-carrier M&A expected. AIG’s structural transformation is complete with Corebridge separated. Tokio Marine Holdings is focused on organic growth and selective bolt-on acquisitions globally. Liberty Mutual is mutual and not subject to M&A pressure. W.R. Berkley remains publicly traded and committed to its decentralized model. Chubb, Markel, and Zurich are not targets in the visible 2026 outlook.

25.7. SRS Acquiom Deal Terms Benchmark 2024-2025

Confidence: HIGH. SRS Acquiom’s annual M&A Deal Terms Study is the single best industry benchmark for buy-side R&W structural variables. SRS Acquiom collected data on more than 1,500 private-target M&A deals it administered as escrow agent and shareholder representative between 2023 and 2025 (SRS Acquiom DTS 2025; DTS 2024). Key findings from the 2025 study with relevance to R&W carriers:

• R&W penetration in private deals: 73% of studied deals carried R&W in 2025, up from 67% in 2024 and 56% in 2022.
• No-survival / public-style structure: 45% of studied deals had no seller indemnity survival post-closing, with R&W as the sole recourse, up from 38% in 2024.
• Median initial retention: 0.75% of enterprise value (0.7% to 0.85% range) for deals in the US$100 million to US$500 million band; 0.5% (0.4% to 0.6% range) for deals above US$500 million.
• Median drop-down retention at 12 months: 0.5% of EV for sub-US$500 million deals; 0.3% for above US$500 million.
• Median escrow size: 0.5% of EV on deals carrying R&W, down from 1.5% on deals without R&W (excluding pure-public-style no-survival deals).
• Median R&W limit: 10% of EV (with material variation: 8% to 15% range depending on deal-by-deal underwriting).
• Special indemnity holdbacks: 28% of deals with R&W carried a special indemnity holdback in addition to R&W, typically for identified pre-closing tax positions, identified environmental issues, or specific litigation matters.
• Materiality scrape: 79% of deals with R&W included a double materiality scrape (breach determination + damages calculation).
• Sandbagging language: 31% of deals had pro-sandbagging provisions, 25% had anti-sandbagging, and 44% were silent.

SRS Acquiom’s data also disaggregates by deal size band, industry, and buyer type (PE versus strategic). Notable patterns: strategic-buyer deals more frequently carry seller indemnity survival in addition to R&W (40% versus 22% for PE-led deals); deals in software and technology more frequently use no-survival walk-away structures (52% versus 41% in industrial manufacturing); cross-border deals with non-US sellers more frequently carry W&I plus R&W in parallel (62% in 2025 versus 48% in 2023).

26. Counter-Narrative Findings

This research desk identified five counter-narrative points that contradict common practitioner assumptions:

1. The 2024 soft market was not a structural change. Practitioners writing through 2024 often assumed the pricing trough would persist. The 16% NA RoL rise in 2025 disproves the structural-decline thesis. The 2024 trough was driven by capacity competition and PE deal-volume compression, both of which reversed in 2025.
2. R&W is not a single-broker market. Practitioners often default to Aon or Marsh as the only option. WTW and Lockton each maintain credible practices, and competitive broker selection on deals above US$500 million EV typically yields 0.25 to 0.5 percentage points of RoL savings.
3. Hub International did not acquire any major M&A insurance practice 2024-2026. Speculation about Hub building a top-four R&W practice through acquisition is not borne out by public filings.
4. The MGA layer does not always equate to lower-quality paper. Euclid Transactional, now CRC Group MGA, writes on A-rated US insurers. Practitioners should evaluate the underlying carrier paper rather than the MGA brand.
5. Claim notification frequency at one broker does not equal the market. The Aon +26% / Marsh -9% notification divergence reflects portfolio composition, not market direction.

27. Limitations and GAPs

GAP: carrier-level premium volume in R&W is not publicly disclosed. GAP: most named placements are not disclosed at the carrier or premium level. GAP: Lockton aggregate placed limits are not publicly disclosed. GAP: Marsh tuck-in detail on regional broker acquisitions is reported in aggregate only. GAP: IRS-specific R&W revenue ruling is absent; practitioners rely on the general business expense framework under IRC section 162.

33. Closing Practitioner Notes

For a PE buyer or strategic acquirer engaging on an R&W placement in the second half of 2026, the practitioner playbook is:

1. Engage all four major brokers (Aon, Marsh, WTW, Lockton) for an initial competitive quote process on deals above US$200 million enterprise value. On smaller deals, engage two brokers.
2. Target carrier set: AIG, Liberty GTS, Tokio Marine HCC for primary on deals where capacity matters; Berkley, Beazley, Markel for excess; Sompo, Zurich, AXA, AGCS for additional excess and cross-border.
3. Pricing target 2026: 3.0% to 3.75% RoL for primary on a clean transaction with no known issues; 3.5% to 4.0% with industry overlays (healthcare, financial services, technology with cyber concentration).
4. Retention target 2026: 0.5% to 0.75% EV on deals above US$500 million; 0.75% to 1.0% on smaller deals; insist on drop-down to 0.3% to 0.5% at 12 months.
5. Carrier selection priorities: AM Best A or better; claims-handling track record; capacity needed for the program; broker-specific carrier preference.
6. Tax insurance: place alongside R&W for specific identified tax positions; expect 1% to 6% RoL.
7. Cyber and IP: negotiate carve-back for cyber; recognize that IP losses are the fastest-growing claim category and likely to be a 2027-2028 underwriting tightening point.
8. Master policy framework: if the buyer is a serial acquirer or PE platform with three or more deals per year, pre-negotiate a master framework for accelerated bolt-on coverage.

The R&W product is now mature, mainstream, and structurally embedded in private M&A practice. The 2024 soft market was an anomaly driven by capacity competition and weak M&A volume. The 2025-2026 firming reflects the underlying loss curve catching up. Practitioners should expect 2026 to be more disciplined than 2024 but less expensive than 2022.
