What Is AIG?
AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy. 1,2

What Is Representations and Warranties Insurance?

Key Differences in Representations and Warranties Insurance
Support across the deal timeline
AIG describes M&A underwriters, prompt transaction support, multinational expertise, and claims professionals for complex disputes. Heffernan's account of its Private Equity and M&A practice focuses on pre-close diligence, benchmarking and searching for hidden liabilities, then insurance planning for the company after closing. A deal team comparing them should distinguish policy-side underwriting and claims expertise from broader brokerage work that continues into the acquired company's insurance program. 3 7
Deal context and policy mechanics
AIG describes an R&W product that can be structured as shared, layered, or excess coverage. Heffernan groups RWI with contingent, environmental, tax, and litigation-buyout products under transactional risk mitigation, and says it serves private equity firms and strategic investors. A buyer should ask Heffernan which carrier and policy structure are proposed for this deal; AIG's structure options still require confirmation against the specific purchase agreement. 3 7

AIG vs Heffernan Insurance Brokers: Representations and Warranties Insurance: documented features by provider
| Criteria | AIG Representations and Warranties Insurance | Heffernan Private Equity and M&A Practice — Representation & Warranty Insurance |
|---|---|---|
| Role in This Line | AIG markets a transaction-specific R&W product and says coverage is written through AIG non-admitted carriers only. The particular issuing entity must be confirmed in the buyer’s transaction documents. 3Company-reported. Role in this product is limited to the description on the linked AIG source. | Heffernan's Private Equity and M&A (HIB) Practice arranges representation and warranty (RWI) insurance for deal buyers and sellers as part of a broader transactional-risk brokerage, rather than underwriting the coverage itself. 7Company-reported. Private Equity and M&A page as read on 2026-09-23. |
| Who It’s For | AIG describes R&W insurance for buyers or sellers in merger and acquisition transactions and publishes a deal-size range as a marketing guide. That range is not an eligibility promise for a particular transaction. 3Company-reported. Audience is the segment AIG names on the linked source; this is not an underwriting decision, quote or guarantee of availability. | Heffernan markets this practice to private equity firms and strategic investors doing mergers and acquisitions, covering both enterprise-level and transactional liability needs. 7Company-reported. Private Equity and M&A page as read on 2026-09-23. |
| Coverage Features | AIG says the product may protect against financial loss from breach of sellers’ representations and warranties. The page lists shared, layered and excess structures; policy wording and transaction diligence control the actual coverage. 3Company-reported. AIG’s public product description is not the policy. Actual entitlement depends on the applicable issued form, endorsements and declarations. | Heffernan says RWI safeguards a buyer and seller's agreed understanding of a deal, and groups it under 'Transactional Risk Mitigation' alongside contingent liability, environmental liability, tax liability, and litigation-buyout coverage. 7Company-reported. Private Equity and M&A page as read on 2026-09-23; the page does not describe RWI's specific insuring agreement, exclusions, retention structure, or limits. |
| Limits and Retentions | AIG advertises limits up to $100 million per transaction and a typical retention reference of 1.0% of enterprise value dropping to 0.5% after 12 months. These are published product parameters, not a buyer-specific quote or guarantee. 3Not publicly disclosed. This statement reports only what the linked public source discloses and does not substitute for a quote or issued policy. | The reviewed page does not publish limits, retention levels, or premium ranges for representation and warranty policies. 7Not publicly disclosed. Private Equity and M&A page as read on 2026-09-23. |
| Risk Services | AIG describes M&A underwriters, prompt transaction support, multinational expertise and dedicated claims professionals for complex transactional disputes. These services are not a promise to accept or pay a claim. 3Company-reported. The linked page describes company-reported support; specific account services and third-party arrangements must be confirmed. | Heffernan describes pre-close due diligence (a detailed review, benchmarking and a search for hidden liabilities), group purchasing across its private-equity clients, and insurance planning for the company after closing. 7Company-reported. Private Equity and M&A page as read on 2026-09-23. |
| How to Apply | Confirm in your quote. | Heffernan invites private equity and M&A clients to contact the practice directly; the page does not describe a self-service quote or online application path. 7Company-reported. Private Equity and M&A page as read on 2026-09-23. |
