Insureds in Taiwan requiring all-risks insurance coverage may choose either commercial fire comprehensive insurance policy or ABI all-risk insurance policy (known as ABI form) to cover their properties. If an insured chooses ABI Form, it must meet the definition of huge sum insured, which means the sum insured to be more than NT$3 billion for one single address or the total insured amount to be more than NT$5 billion for all insured addresses. Using ABI form policy would be easier to arrange reinsurance in the international reinsurance market and increase the willingness of international reinsurers to accept reinsurance for this kind of business. In addition, ABI form policy is a generalized insurance policy with relatively complete protection for property damage and business interruption, so ABI form policy is widely used in mega account in Taiwan. As ABI form Policy is an English policy, many underwriters of local insurers still have questions about the policy clauses. Therefore, this research hopes to analyze the clauses of ABI form policy and make a comparison with the clauses of comprehensive commercial fire insurance policy in Taiwan. The comparison will help the insurance professionals in Taiwan to understand the differences and advantages of the two policies. This research finds that the clauses in various versions of ABI form policy over the years are not consistent and are prone to disputes. Compared with the standardization of the domestic commercial fire comprehensive insurance policy, the future ABI form policy should have consistent basic clauses, and then add other optional clauses or endorsements to make the policy more clear to meet the different needs of insureds.
