Lesson Content/Board Summary
Insurance (Continued)
Marine Insurance Policies
Marine insurance covers loss or damage of ships, cargo, terminals, and any transport by which property is transferred, acquired, or held between the points of origin and final destination.
The following are types of marine insurance policies:
- Time Policy: This policy covers the ship or cargo for a specific period, usually not exceeding 12 months, regardless of the number of voyages made.
- Voyage Policy: This policy covers the ship or cargo for a specific voyage from one port to another, irrespective of the time taken.
- Valued Policy: In this policy, the value of the subject matter insured (e.g., ship or cargo) is agreed upon and stated in the policy document at the time of contract.
- Unvalued Policy: Here, the value of the subject matter insured is not stated in the policy document but is left to be ascertained in case of a loss.
Marine Losses
Marine losses refer to the destruction, damage, or disappearance of insured property (ship or cargo) covered by a marine insurance policy.
The following are types of marine losses:
- Total Loss: This occurs when the insured property is completely destroyed or lost, either actually or constructively.
- Actual Total Loss: The subject matter insured is completely destroyed, irretrievably lost, or so damaged as to cease to be a thing of the kind insured (e.g., a ship sinks to the bottom of the ocean).
- Constructive Total Loss: This occurs when the cost of recovery, repair, and future salvage of the insured property would exceed its value when repaired. The owner can abandon the property to the insurer and claim total loss.
- Partial Loss: Any loss that is not a total loss. The insured property is damaged but not completely destroyed.
- General Average Losses: These are losses caused by sacrifices made or expenses incurred voluntarily and reasonably in times of common danger, for the preservation of the property involved in a common maritime adventure. These losses are shared proportionally by all parties interested in the voyage (ship, cargo, freight).
- Particular Average Losses: These are partial losses of the subject matter insured, caused by an accident, and which are not general average losses. They are borne solely by the owner of the property lost or damaged.
Underwriting
Underwriting is the process by which an insurance company assesses the risk of insuring a particular person or property, determines the terms and conditions of the policy, and calculates the appropriate premium to charge.
Re-insurance
Re-insurance is the practice where one insurance company (the ceding company) transfers part of its risk to another insurance company (the re-insurer). This helps the ceding company to reduce its exposure to large losses and allows it to underwrite more policies.
Co-operative Insurance of Nigeria
Co-operative insurance involves a group of individuals or organizations pooling their resources to provide insurance coverage for themselves. Members typically share in the profits and losses, and the primary aim is to provide affordable and accessible insurance to its members rather than maximizing profit.
