## What Is Umbrella and Excess Liability Insurance?

Umbrella or excess insurance adds liability limits above the policies named in the quote after a covered claim exhausts their limits. It may fit if a contract sets higher limits; check which primary policies are listed and any gaps between them. [11](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance "Liability Insurance") [12](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [13](https://www.insurance.ca.gov/0200-industry/0050-renew-license/0200-requirements/casualty/lines-of-ins.cfm "Lines of Insurance") [14](https://www.coverdash.com/coverage "Coverage Hub") [15](https://kinro.com/products "Products")

## Key Differences in Umbrella and Excess Liability Insurance

### Founder Shield places coverage with third-party carriers

Founder Shield says it is a retail brokerage and places umbrella policies with carriers rated A- or better by AM Best, selected for the client's industry; the actual insurer depends on placement. Liberty Mutual lists umbrella/excess directly in its commercial catalogue and wholesale coverage list, though the issuing entity still needs to be confirmed for a quote. Ask each who will issue the policy and which entity appears on the declarations. [3](https://foundershield.com/insurance-faqs/general-faqs/how-do-you-decide-which-carriers-to-approach/ "How Do You Decide Which Carriers to Approach?") [9](https://business.libertymutual.com/commercial-solutions/ "Commercial Insurance Solutions")

### Founder Shield describes a wider set of personal and business buyers

Founder Shield names business owners, property owners, high-net-worth individuals, and professionals such as doctors, lawyers, and architects. Liberty Mutual's cited wholesale page places umbrella/excess in a business-distribution context. If you need a strictly commercial layer, ask Founder Shield to confirm the form is business-only and ask Liberty Mutual whether the wholesale or commercial team is appropriate. [6](https://foundershield.com/coverage/umbrella-insurance/ "Umbrella Insurance") [10](https://business.libertymutual.com/industries/wholesale/ "Wholesale Distribution")

### Both require a placement conversation

Founder Shield says buyers request coverage through its website or an advisor, after which its placement team approaches carriers. Liberty Mutual distributes through brokers and agents and lists wholesale umbrella/excess. Share your underlying policies and contract limits with each intermediary to identify the carrier, attachment point, and available capacity. [7](https://foundershield.com/about-us/ "About Us") [10](https://business.libertymutual.com/industries/wholesale/ "Wholesale Distribution")

## What to Confirm in Umbrella and Excess Liability Insurance Quotes

- Ask Founder Shield which carrier and AM Best rating apply, whether the form is commercial-only, and what limits are available. [3](https://foundershield.com/insurance-faqs/general-faqs/how-do-you-decide-which-carriers-to-approach/ "How Do You Decide Which Carriers to Approach?")
- Ask Liberty Mutual's agent which entity will issue the policy and whether its umbrella layer meets your contract's attachment requirement. [10](https://business.libertymutual.com/industries/wholesale/ "Wholesale Distribution")

## Offering Details

| Criteria | Founder Shield Umbrella Insurance | Umbrella and Excess Liability |
| --- | --- | --- |
| Role in This Line | Founder Shield is a retail insurance brokerage, described on its site as “the innovation arm of The Baldwin Group,” and places Founder Shield Umbrella Insurance with third-party carriers rather than underwriting the policy itself. [7](https://foundershield.com/about-us/ "About Us") (Evidence: Company-reported; scope: About-us page; applies to Founder Shield's brokerage model generally, restated here for this line..) | Liberty Mutual lists umbrella and excess liability in its commercial catalogue and in a wholesale-industry coverage list.

| Issuing Insurer | Founder Shield says it places policies, including Founder Shield Umbrella Insurance, only with carriers rated A- or better by AM Best, chosen for the client's industry. It does not name the issuing insurer for this line; that depends on which carrier the policy is placed with.

(Evidence: Company-reported; scope: General carrier-selection FAQ, not specific to this line's placements..) | Confirm in your quote. |
| Who It’s For | Founder Shield's page describes umbrella coverage broadly for high-net-worth individuals, business owners, property owners, and professionals such as doctors, lawyers or architects; it does not distinguish a business-only umbrella product from personal umbrella coverage. [6](https://foundershield.com/coverage/umbrella-insurance/ "Umbrella Insurance") (Evidence: Company-reported; scope: Umbrella Insurance product page; wording mixes personal and commercial umbrella use cases..) | The commercial business pages distribute products through brokers and agents.

Not policy wording, underwriting approval, state eligibility or a coverage guarantee..) |

[6](https://foundershield.com/coverage/umbrella-insurance/ "Umbrella Insurance") (Evidence: Company-reported; scope: Product page; the issued policy and declarations control actual coverage..) | Its wholesale page names umbrella/excess cover as an option for that industry; limits and attachment terms are not established here.
