Loss Expense Reserve

Another name for claims reserve. The expression is also often used in association with the reserve deposited by a reinsurer with the cedant to cover in part outstanding claims (exact terms would indicate which party received the investment income on associated assets).

Loss in Excess of Policy Limits

An amount of loss which exceeds the original policy limits, but is otherwise covered under the policy, for which the insurer is potentially responsible by reason of its action or omissions, including failure to settle within the policy limits, in defending the insured under the policy. Typically an Excess Policy Limits loss is awarded by a court after an insured brings suit against its insurance carrier.

Loss In Progress Rule

Insurance can only indemnity an insured against risks of loss that are both unknown and unexpected. If a loss is already in progress at the time the policy is acquired the loss is no longer fortuitous but a rather a certainty. The Loss in Progress Rule prohibits recovery for a non-fortuitous loss.
