Key Terms to Know
Follow-Form
An umbrella that follows the terms and conditions of the underlying policy — covering the same risks with expanded limits. Most commercial umbrellas are follow-form.
Minimum Underlying Limits
Umbrellas require your primary policies to carry minimum limits before the umbrella attaches. Typically: $1M GL, $1M employer's liability, $1M commercial auto.
Drop-Down Coverage
When the underlying policy is exhausted — whether by claims or by the carrier's insolvency — the umbrella drops down and acts as primary coverage.
Excess vs Umbrella
A true umbrella is broader than excess — it can cover losses not covered by underlying policies (but must be specifically listed). An excess policy strictly follows underlying terms.
