1. Principle of Indemnity: Insurance is a contract of indemnity whereby the insured is compensated only to the extent of the actual loss suffered. The insured is never allowed to make a profit or gain an enriched financial position from insurance. Here, Jeevan's actual loss is ₹3,00,00,000. If he recovers ₹3,00,00,000 from each insurer, he would collect ₹6,00,00,000, reaping an unlawful profit of ₹3,00,00,000.
2. Principle of Contribution: When property is insured with more than one insurer (double insurance), all insurers contribute towards the actual loss in proportion to the sum insured with each.
Mathematical Contribution Formula:
Liability of Insurer = (Sum Insured with that Insurer ÷ Total Sum Insured) × Actual Loss
• Total Insured Value = ₹6,00,00,000 + ₹4,00,00,000 = ₹10,00,00,000 (Ratio 6 : 4 or 3 : 2)
• AIG Ltd. will pay: (6/10) × ₹3,00,00,000 = ₹1,80,00,000
• MetLife Ltd. will pay: (4/10) × ₹3,00,00,000 = ₹1,20,00,000
• Total claim received by Jeevan: ₹1,80,00,000 + ₹1,20,00,000 = ₹3,00,00,000 (Exact actual loss).
