As in GIM8040, a direct insurer writes the following contracts:

Policy	Sum Insured	听
拢	Premium (100%)	听
1	25,000	200
2	50,000	300
3	100,000	500

A five line surplus reinsurance contract is entered into with a retention of 拢10,000. The limit of the reinsurer鈥檚 liability is 5 x 拢10,000 = 拢50,000. Reinsurance payments are calculated as follows:

(Limit of reinsurer鈥檚 liability - Retention) / Sum Insured x Claim.

If a claim on policy 1 of 拢12,000 is paid then the reinsurer will pay 拢7,200

[(25,000 - 10,000)/25,000 x 拢12,000]

A claim of 拢35,000 on policy 2 would result in the reinsurer paying 拢28,000

[(50,000 - 10,000)/50,000 x 拢35,000]

A claim of 拢60,000 on policy 3 would give a reinsurance payment of 拢24,000

[(50,000 - 10,000)/100,000 x 拢60,000]

Premiums (gross of reinsurance commission) are allocated on a similar basis:

• Policy 1 (25,000 - 10,000)/25,000 x 拢200 = 拢120
• Policy 2 (50,000 - 10,000)/50,000 x 拢300 = 拢240
• Policy 3 (50,000 - 10,000)/100,000 x 拢500 = 拢200

Where reinsurance is by way of quota share or surplus treaty, premium deposits and loss reserve deposits may appear in the balance sheet. These are usually described as deposits from ceding insurers.

A premium deposit occurs where when reporting underwriting year experience (see GIM2080) the insurer retains part of the ceded premiums as a premium reserve. It will pay interest on the deposits. They are broadly equal in amount to an unearned premium provision (see GIM2100), though the calculation may be less scientific. The retention of such deposits is a safeguard against the credit risk of the reinsurer becoming insolvent and may be a regulatory requirement.

A loss reserve deposit may be encountered when reporting either accident or underwriting year experience. It represents a deposit by the reinsurer of at least part of their share of insurer鈥檚 outstanding loss reserves. As with premium deposits, interest is payable on the deposit. Such deposits give comfort to the ceding insurer and may be required by the insurer鈥檚 regulator.
