Umbrella and Excess Liability

Purpose

Umbrella and excess policies provide additional limits of liability above underlying policies.

Self-insured retentionDeductible for drop-down claims
Broad coverageComprehensive liability protection

No self-insured retentionUnderlying policy is the retention
Narrow coverageLimited to underlying terms

Underlying Insurance Requirements

Umbrellas typically require:

  • Commercial General Liability
  • Auto Liability
  • Employers Liability
  • Specified minimum limits on each

When to Recommend Umbrella/Excess

  • High net worth individuals
  • Businesses with significant liability exposure
  • Professionals with malpractice risk
  • Companies with fleet vehicles
  • Manufacturers with products liability risk

Wisconsin-Specific Liability Considerations

Comparative Negligence Impact

Wisconsin's modified comparative negligence affects liability claims:

  • Damages reduced by plaintiff's fault percentage
  • No recovery if plaintiff more than 50% at fault
  • Joint and several liability rules apply

Statute of Limitations

Claim TypeLimitation
Personal injury3 years
Property damage6 years
Contract6 years
Products liability3 years from discovery

Direct Action

Wisconsin allows direct action against liability insurers:

  • Injured parties can sue insurer directly
  • Include insurer as defendant
  • Jury may be aware of insurance

Exam Tip: Umbrella policies provide both excess coverage AND may drop down to cover claims not covered by underlying policies (subject to a self-insured retention). Excess policies only follow the terms of the underlying policy.
