Expenses, Erosion, and Exhaustion.

Amerisure and Arch disputed whether Arch exhausted its policy limits.  The Arch policy had an endorsement that said the coverage section “is amended as follows: The provision: ‘These payments will not reduce the limits of insurance. is deleted in its entirety and is replaced with the following provision: ‘These payments will reduce the limits of insurance.’”

Amerisure argued that the “expenses” referred to by the endorsement could not be read as including attorneys fees without contradicting another, more specific portions of the policy: ” Our right and duty to defend end[s] when we have used up the applicable limit of insurance in the payment of judgments or settlements under Coverages A or B or medical expenses under Coverage C.”

The Fifth Circuit disagreed, reasoning: “This construction reads the endorsement out of the policy as, logically, there can never be an end to the duty to defend unless the insurer
pays the policy limits in indemnity payments.”  Accordingly, Arch had an “eroding” policy with the insured, and its payments of attorneys fees had exhausted the policy limits.  Amerisure Mutual Ins. Co. v. Arch Specialty Ins. Co., No. 14-20239 (April 21, 2015).
