ABC Insurance Company is considering to buy reinsurance from 123 Re. There are two
types of agreement they have in mind: quota share treaty or surplus share treaty. Consider
the two policies (lines) and answer the following questions under the two types of terms of
the agreement.
Policy A insures Building A for $10,000 for a premium of $300, with one loss of $5,000.
Policy B insures Building B for $12,000 for a premium of $350, with one loss of $4,000.
a. Under a quota share treaty with a $250,000 limit, a retention of 40%, and a cession of
60%, what are the amount of insurance, premiums, and losses ABC Insurance Company
is responsible for the two policies?
b. Under a surplus share treaty where ABC retains a line of $10,000 and a maximum ces-
sion of $225,000, what are the amount of insurance, premiums, and losses 123 Re is
responsible for the two policies?
1. Quota Share Treaty
Policy A
Risk sharing = ABC Insurance Company retains 40% i.e. $10,000 *40% = $ 4,000 and 123 Re will cede 60% i.e. $ 10,000 * 60% = $ 6,000
Premium Sharing = ABC Insurance Company retains 40% i.e. $ 300 *40% = $ 120 and 123 Re will cede 60% i.e. $ 300 * 60% = $ 180
Loss Sharing = ABC Insurance Company retains 40% i.e. $ 5,000 *40% = $ 2,000 and 123 Re will cede 60% i.e. $ 5,000 * 60% = $ 3,000
Policy B
Risk sharing = ABC Insurance Company retains 40% i.e. $12,000 *40% = $ 4,800 and 123 Re will cede 60% i.e. $ 12,000 * 60% = $ 7,200
Premium Sharing = ABC Insurance Company retains 40% i.e. $ 350 *40% = $ 140 and 123 Re will cede 60% i.e. $ 350 * 60% = $ 210
Loss Sharing = ABC Insurance Company retains 40% i.e. $ 4,000 *40% = $ 1,600 and 123 Re will cede 60% i.e. $ 4,000 * 60% = $ 2,400
