Total value of internal layer to which the percentage ceded is applied.
For example, if the policy is a $10M policy on which 25% of $3M excess of $7M is ceded to a facultative reinsurer, the Internal Layer Amounts would be $7M for the first layer and $3M for the second layer. Format for coding is 7000000 for the first layer, 3000000 for the second layer, etc.
