Quotes take 24 hours to ten business days, depending on your risk.

## What Is Aon?

Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account.

## What Is Management Liability Insurance?

Management liability packages can combine D&O and employment-practices coverage for leader and workplace claims, while benefit-plan protection may be a separate part. Shared limits can let a claim in one part reduce what is available for another, so compare the limits across the quote. [8](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [9](https://www.thehartford.com/management-liability-insurance "Management Liability Insurance") [10](https://www.chubb.com/us-en/business-insurance/forefront.html "The ForeFront Portfolio") [11](https://asset.trvstatic.com/download/assets/pdo-3001.pdf/d66bd58e63c911ee99d14294a32ecb95 "Private Company Directors and Officers Liability Coverage") [12](https://asset.trvstatic.com/download/assets/lia-3001.pdf/e79a6b6c63ca11eeaa7806e978c86228 "Liability Coverage Terms and Conditions") [13](https://asset.trvstatic.com/download/assets/pdo-1100w-ind.pdf/d44fa35c63c911eea5a70eda10c0a4d0 "Private Company Directors and Officers Liability Coverage Application")

## Key Differences in Management Liability Insurance

### What the Published Program Says

Alliance Risk breaks management liability into D&O, employment practices liability and fiduciary coverage, with commercial crime commonly added; it says entry-level packages may share one aggregate limit across the core lines. Aon says it designs management-liability programs to protect partners and managers in professional partnerships, but its reviewed page does not explain whether limits are shared or separate. For a company weighing a package, Alliance Risk’s shared-limit discussion identifies a concrete issue to resolve before choosing structure. [4](https://joinalliancerisk.com/management-liability-insurance/ "Management Liability Insurance: How D&O, EPLI, and Fiduciary Fit Together") [7](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice")

### Placement and Buyer Questions

Alliance Risk recommends D&O at a first priced financing, EPLI when headcount reaches double digits and fiduciary coverage when a benefits plan starts. Aon’s audience is law, accounting and consulting firms and it describes advisors supporting risk decisions, without comparable trigger guidance. The recommendations are not policy terms; use them to ask when each exposure begins and whether a standalone or packaged placement suits your organization. [4](https://joinalliancerisk.com/management-liability-insurance/ "Management Liability Insurance: How D&O, EPLI, and Fiduciary Fit Together") [7](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice")

## What to Confirm in Management Liability Insurance Quotes

- Ask Alliance Risk to show how one claim could reduce remaining aggregate limits across the package. [4](https://joinalliancerisk.com/management-liability-insurance/ "Management Liability Insurance: How D&O, EPLI, and Fiduciary Fit Together") [7](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice")
- Ask Aon whether each management-liability part has a separate limit and what company events should trigger adding it. [4](https://joinalliancerisk.com/management-liability-insurance/ "Management Liability Insurance: How D&O, EPLI, and Fiduciary Fit Together") [7](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice")

## Offering Details

| Criteria | Alliance Risk Management Liability Insurance | Aon Management Liability brokerage and risk-advisory offering |
| --- | --- | --- |
| Role in This Line | Alliance Risk is a brokerage. For management liability, it advises clients on whether to buy directors and officers (D&O), employment practices liability (EPLI) and fiduciary liability as a single packaged program or as standalone policies. [4](https://joinalliancerisk.com/management-liability-insurance/ "Management Liability Insurance: How D&O, EPLI, and Fiduciary Fit Together") (Evidence: Company-reported; scope: Dedicated management-liability page, accessed 2026-09-23..) | Aon presents Management Liability as a line its Professional Services Practice helps arrange or advise on for professional-service firms. Aon is describing a global brokerage and advisory service, not issuing the underlying policy. The producing legal entity and carrier for any particular placement are not named on this page. [7](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement..) |
| Issuing Insurer | The management liability page does not name the underwriting insurer or insurers behind a packaged program. As a brokerage, Alliance Risk places the coverage with third-party carriers that vary by client. [4](https://joinalliancerisk.com/management-liability-insurance/ "Management Liability Insurance: How D&O, EPLI, and Fiduciary Fit Together") (Evidence: Not publicly disclosed; scope: Dedicated page, accessed 2026-09-23; no insurer or carrier list disclosed..) | The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. [7](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not found in reviewed sources; scope: Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement..) |
| Who It’s For | Alliance Risk recommends turning on each line at a specific trigger: D&O at the company's first priced financing round, EPLI once headcount grows into double digits, and fiduciary liability when a benefits plan such as a 401(k) launches. [4](https://joinalliancerisk.com/management-liability-insurance/ "Management Liability Insurance: How D&O, EPLI, and Fiduciary Fit Together") (Evidence: Company-reported; scope: "How to structure the program as you scale" section, aimed at venture-backed companies..) | Aon identifies law, accounting and consulting firms as the audience for its global Professional Services Practice. That audience scope does not establish eligibility for every firm or other business. [7](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement..) |
| Coverage Features | Alliance Risk describes three core lines inside a management liability program: D&O, EPLI and fiduciary liability, with commercial crime as a common fourth line added to the same program. [4](https://joinalliancerisk.com/management-liability-insurance/ "Management Liability Insurance: How D&O, EPLI, and Fiduciary Fit Together") (Evidence: Company-reported; scope: Dedicated page; each core line links out to Alliance Risk's separate line-specific pages for more detail..)<br><br>Alliance Risk says entry-level packaged programs often share a single aggregate limit across D&O, EPLI and fiduciary, so a large claim on one line can reduce what is left for another line the same policy period. It says a specialist broker can structure shared versus separate limits to avoid that. [4](https://joinalliancerisk.com/management-liability-insurance/ "Management Liability Insurance: How D&O, EPLI, and Fiduciary Fit Together") (Evidence: Company-reported; scope: "The shared limit problem" section of the dedicated page..) | Aon says it designs management-liability programs for professional partnerships to help protect partners and managers exposed to business-operation liabilities. It describes a practice program, not a named insurer’s policy form or a guaranteed coverage result. [7](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s marketing description of the brokerage/coverage area. The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage..) |
| Limits and Retentions | Alliance Risk publishes indicative annual premium ranges for the packaged program: roughly $5,000-$15,000 at seed (D&O plus EPLI), $15,000-$50,000 at Series A/B (D&O, EPLI and fiduciary), and $50,000-plus at late stage or pre-IPO. It does not publish specific dollar coverage limits or retentions for each stage; those come with a quote. [4](https://joinalliancerisk.com/management-liability-insurance/ "Management Liability Insurance: How D&O, EPLI, and Fiduciary Fit Together") (Evidence: Company-reported; scope: "What the package costs by stage" table, described as indicative for venture-backed companies..) | The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. [7](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not publicly disclosed; scope: Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed..) |
| Risk Services | Confirm in your quote. | Aon says its professional-services advisors use industry knowledge, insights, data and tools to support risk-management and human-capital decisions. This is a company-described advisory service, not a claim outcome or policy benefit. [7](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated..) |
| How to Apply | You apply for management liability by scheduling a consultation with an Alliance Risk advisor, who recommends a packaged program or a standalone approach based on your stage, board composition and financing history. [4](https://joinalliancerisk.com/management-liability-insurance/ "Management Liability Insurance: How D&O, EPLI, and Fiduciary Fit Together") (Evidence: Company-reported; scope: Closing call-to-action on the dedicated page..) | Confirm in your quote. |
| Claims Support | Alliance Risk says that when one event triggers more than one management-liability line, such as an executive's exit that produces both an EPLI charge and a D&O suit against the board, a single packaged program puts one carrier and one defense team on both threads instead of separate insurers disputing which one leads. [4](https://joinalliancerisk.com/management-liability-insurance/ "Management Liability Insurance: How D&O, EPLI, and Fiduciary Fit Together") (Evidence: Company-reported; scope: "One event, two policies" section, illustrated with three placement examples Alliance Risk says it has handled..) | Confirm in your quote. |
