Excess Liability Coverage (or ELC) is very similar to Umbrella Coverage in the sense that it is an added feature to an existing policy. However, unlike Umbrella Coverage, it can only be added to one policy rather than multiple. This coverage is very beneficial for businesses that have a high risk chance of something going wrong in one particular area. With the added coverage that acts like a cushion when you run out of liability coverage on one policy, or even on your umbrella policy, your business will be kept safe and sound.
