An excess layer, umbrella liability policy or excess of loss treaty that lowers, i.e. drops down, its excess point if the limits of the underlying layer or retention have been exhausted. ‘Drop downs’ are subject to annual aggregate limits. The insured/reinsured may be able to absorb a given retention level on one loss but additional losses need the added protection afforded by the drop-down. ‘Drop down’ covers may also pick up gaps in cover as may happen in umbrella liability policies and master global policies sitting over local policies. See TOP AND DROP.
