Intangible Assets

AIG benefits from long-standing insurance licenses, regulatory approvals, and claims-handling know-how, but these assets are broadly available to large global peers such as Chubb, Travelers, and Allianz.

Its brand and distribution relationships support renewal retention in commercial and specialty lines, yet peer brands with deeper underwriting reputations often command stronger pricing power.

Insurance expertise can improve risk selection and product design, but underwriting discipline is not exclusive to AIG and is more consistently evidenced at top-tier peers like Chubb.

Intangible assets matter most where customers value claims certainty and global servicing, but AIG’s franchise is more replaceable than peers with stronger specialty niches or more durable broker preference.

Switching Costs

Commercial insurance programs create some friction to switching because policy wording, claims history, and broker workflows must be re-underwritten, but this is an industry-wide feature rather than an AIG-specific lock-in.

Large-account relationships can persist across renewal cycles, yet peers such as Chubb and Travelers often have equal or stronger retention because of deeper underwriting consistency and service reputation.

AIG’s multinational clients may face administrative complexity in changing carriers, but that complexity is shared by other global insurers and does not create durable exclusivity.

Switching costs support renewal stability, but they are not high enough at AIG to materially prevent customers from moving to peers when pricing or coverage terms improve.

Network Effects

AIG does not operate a platform where each additional customer materially increases value for other customers, so it lacks the self-reinforcing network effects seen in true ecosystem businesses.

Broker and reinsurer relationships can improve market access, but those relationships are bilateral and portable, unlike network effects that compound with scale and usage.

Claims data and underwriting experience can improve pricing models, yet peers such as Allianz, Chubb, and Zurich can build similar datasets, limiting any durable network advantage.

Because insurance is sold through competitive channels rather than a closed network, AIG’s customer base does not create meaningful peer-dependent lock-in.

Cost Advantage

AIG’s scale can spread overhead across a large premium base, but its TTM ROIC of about 4.9% and ROCE of about 6.0% do not indicate a clear cost advantage versus stronger peers.

The company’s asset turnover of 0.163 suggests a capital-intensive model with limited operating leverage, which weakens evidence of superior unit economics.

Global insurers such as Chubb and Travelers typically demonstrate more consistent underwriting profitability, implying AIG has not converted scale into a durable cost edge.

Any procurement, reinsurance, or technology scale benefits are offset by the complexity of operating a diversified international insurance portfolio.

Efficient Scale

AIG participates in markets where scale matters in claims infrastructure, capital management, and global servicing, but the industry remains highly competitive and not naturally monopolistic.

Its size can help absorb catastrophe volatility and support multinational clients, yet peers like Allianz, Zurich, and Chubb also operate at sufficient scale to match these capabilities.

No evidence suggests AIG controls a uniquely constrained niche where one or two firms can profitably serve the market with limited competition.

Efficient scale provides some durability in specialized commercial and international lines, but it does not create the kind of peer dependency that would justify an exceptional moat score.

Overall Score

AIG has a durable but not exceptional moat, with moderate support from regulatory barriers, client switching friction, and scale in global insurance, but it lacks the stronger underwriting reputation, structural lock-in, or ecosystem-like advantages that make peers such as Chubb more defensible.
