"Single risk" means the insured amount of any policy or contract of title insurance issued by a title insurer unless two or more policies or contracts are simultaneously issued on different estates in identical real property, in which event it means the sum of the insured amounts of all such policies or contracts. Any policy or contract which insures a mortgage interest that is excepted in a fee or leasehold policy or contract, and which does not exceed the insured amount of the fee or leasehold policy or contract, shall be excluded in computing the amount of a single insurance risk.
