Buffer Layer

A stratum of cover between the upper limit of the primary insurer and the attachment point of the excess or umbrella insurer. The ‘buffer layer’ fills the gap. Example: total policy limit of £10 million is arranged as follows: primary layer = £1 million; buffer layer is £1 million in excess of £1 million and the excess/umbrella layer is £8 million in excess of £2 million. In reinsurance terms the buffer layer sits between the working cover/layer and the catastrophe layer. It absorbs relatively large losses that do not occur annually, but do so with some regularity.

The buffer layer is the layer of insurance that resides between the primary layer and the excess layer. For example, suppose Marcia wants to purchase a business umbrella liability, but she is required to carry underlying comprehensive general liability limits of at least $500,000. Marcia has only $300,000 liability coverage and her current insurance company will not increase the primary coverage. Marcia either faces a $200,000 gap in coverage or purchases a $200,000 “buffer.”
