A feature of most corporate liability insurance programs is the tower system of coverage: a primary policy with several overlying excess policies stacked atop one another collectively providing coverage up to a desired (or available) limit of liability. Depending on the size and liability exposures of a policyholder, a tower can consist of dozens of policies providing limits totaling hundreds of millions of dollars. Adding to this complexity, excess policies often share layers of coverage in quota share arrangements, sometimes subscribing to the same policy but more often issuing separate policies for a stated percentage of the quota share whole. To avoid as much as possible an impenetrable web of conflicting coverage terms, excess policies often “follow form” to the underlying coverage (usually to the primary policy) providing the insurer certainty and providing the policyholder a consistent tower of coverage. It is not always possible, though, to obtain clarity and certainty in tower placements. Insurance companies issuing excess coverage may not wish to agree to all the terms included in the underlying policies, and so may offer additional or differing terms, creating inconsistencies in an otherwise monolithic tower. For example, a primary insurer may refuse to cover punitive damages whereas an excess insurer may agree to do so, or vice versa.
