Lexington Insurance Co. v. RLI Insurance Co., No. 19-1426 (7th Cir. 2020)
Annotate this Case
Prime, a trucking company, covered its own liability without insurance for the first $3 million per occurrence and bought excess liability insurance from multiple insurers, following a common industry practice of stacking policies into sequential “layers” of excess insurance coverage. Two accidents occurred in 2015 when Prime was covered by RLI and AIG policies. The two cases settled for $36 million. Prime was covered $3 million for each occurrence. The RLI Policy provided the next layer of coverage with an “Aggregate Corridor Deductible” (ACD) that obligated Prime to pay out an additional $2.5 million annually before RLI began to pay. RLI argued that the ACD sat within RLI’s $2 million layer, leaving RLI with no responsibility for any payment until Prime had both paid $3 million per occurrence and the year’s ACD. AIG argued that the ACD sat below RLI’s $2 million layer, so AIG’s duty to pay would not be triggered until Prime and RLI had together paid $7.5 million for the first occurrence.
The district court found that payments toward the ACD erode RLI’s policy layer. The Seventh Circuit affirmed. The custom-tailored ACD feature of the RLI Policy was ambiguous but undisputed extrinsic evidence shows that RLI is correct. RLI has consistently expressed that Prime’s ACD payments reduce its responsibility for losses; Prime did not disagree before this dispute. The only reasonable inference from the parties’ negotiations is that AIG did not believe the ACD affected the threshold at which its layer began—$5 million per occurrence.
