If the interest is insured against the same perils with two or more insurers, the total amount of compensation shall, in the recourse settlement, be apportioned on the basis of the amounts for which each insurer was liable.
If all of the insurers have disclaimed liability where the interest is also insured with another insurer and the assured has received settlement under the rules contained in Cl. 2-6, sub-clause 3, the rule concerning recourse in sub-clause 1 shall apply correspondingly.
If the assured is entitled to recover costs incurred to prevent or minimise loss from an insurer, that insurer shall, to the extent of his liability, bear the full amount of such costs in the recourse settlement. This applies even if all the insurers have disclaimed liability where the interest is also insured with another insurer.
