This is a dispute between two insurers concerning their respective responsibilities under competing “other insurance” clauses. The trial court declined to prorate their responsibilities on the basis of the combined policy limits, but rather applied the “closer to the risk” test used by the Minnesota courts. Because we are not persuaded to subscribe to the Minnesota doctrine, we reverse and remand.
Larry Boughn was injured in a fall from a pickup truck owned by Steven Crozier and operated by Steven’s brother, Gary Crozier. The accident occurred on Gary’s farm. Steven, as owner of the vehicle, had insurance with National Insurance Association with a $20,000 coverage limit. Gary had automobile liability insurance with the plaintiff, Illinois National Insurance Company, which covered him as the operator of the vehicle up to $25,000. Gary also had farm liability insurance through the defendant, Farm Bureau Mutual Insurance Company, with a policy *671 limit of $300,000. This policy insured Gary for damages for personal injuries caused by accidents on his farm.
Boughn’s tort action against Gary for damages as a result of his injuries was subsequently settled for $72,000. Because National Insurance, under its policy with Steven, was considered the primary insurer, it paid its full policy limit of $20,000. Although Farm Bureau and Illinois National agreed to pay the remaining portion of damages as excess insurers, a dispute arose regarding their contributions under their “other insurance” clauses. Farm Bureau’s provision on “other insurance” provided:
This insurance is excess over any other valid and collectible insurance, except insurance written specifically to cover as excess over the limits of liability that apply in this policy.
Illinois National’s “other insurance” provision provided:
If there is other applicable liability .insurance we will pay only our share of the loss. Our share is the proration that our limit of liability bears to the total of all applicable limits. However, any insurance we provide for a vehicle you do not own shall be excess over any other collectible insurance.
Illinois National brought this action for declaratory judgment seeking pro rata contributions for the settlement remainder. Such a method would have required Illinois National to pay only one-thirteenth (or $5200) of the remaining settlement, with Farm Bureau responsible for the remaining portion. Farm Bureau answered seeking a determination that Farm Bureau’s coverage was limited to the excess over the Illinois National coverage limits. Farm Bureau contends that Illinois National, as an automobile liability insurer, was the primary excess insurer so it should have to pay the amount remaining after Illinois National’s $25,000 coverage had been exhausted.
The case was submitted on stipulated facts. The district court concluded Illinois National should be primarily liable for the remaining settlement and was required to pay the full policy limit of its automobile insurance before any contribution from Farm Bureau. In doing so the court utilized the “closer to the risk” analysis followed in
Illinois Farmers Insurance Co. v. Depositors Insurance Co.,
Illinois National appeals.
I. Our review is on error. Iowa R.App. P. 4. When a case is submitted on stipulated facts, our only task is to construe the provisions of the insurance policies.
Hernandez v. Farmers Ins. Co.,
II. There has been a trend among insurance companies toward enlarging coverage to include other persons in addition to the primary insured.
Aid Ins. Co. (Mut.) v. United Fire & Cas. Co.,
This case involves two insurance policies, each of which has excess clauses. The “other insurance” clause in Farm Bureau’s policy is purely an excess clause. In contrast the “other insurance” clause in the Illinois National policy is pro rata in most instances, except when the vehicle is not owned by the insured. The pickup truck was not owned by Gary, thus Illinois National’s excess clause is controlling.
Illinois National relies on a trilogy of cases. In
Truck Insurance Exchange v. Ma
*672
ryland Casualty Co.,
Shortly thereafter we decided
Union Insurance Co. (Mutual) v. Iowa Hardware Mutual Insurance Co.,
When the insured has coverage from either of two policies, but for the other, and each contains a provision reasonably subject to a construction that it conflicts with a provision in other concurrent insurance, there is a conflict.... [A] repugnancy
between relative provisions of two policies is more equitably resolved by ignoring the two offending clauses. Resultantly Iowa Hardware’s policy, minus its escape clause, covers the insured, while the Union Insurance policy, minus its excess clause, provides like coverage. The insured is thus protected by both insurers which is a reasonable result, since each wrote expanded coverage policies which must have been intended to reach her, and this problem of double insurance was “involuntarily thrust upon the insured through the operation of another insurance contract.” ... [Liability coverage, if any, must be prorated equally between plaintiff and defendant, within the combined limits.
Union Ins. Co. (Mut.),
In applying this pro rata approach, we rejected a rule adopted by some courts that a general escape clause must yield to the more specific excess clause, making the policy containing the more general escape clause primarily liable. See id. at 416. We rejected this approach because the insurers were engaged in a “draftsmanship battle,” crafting their policies in an attempt to “out specific the specific excess provisions” in other insurance policies so as to reduce their liability. Mat 416-17.
Aid Insurance Co. (Mutual)
was the last of the trilogy. There a ear dealership and a customer both had insurance to cover an accident during a test drive.
Aid Ins. Co. (Mut),
The foregoing cases have thus settled the responsibilities in disputes between excess and escape clauses and between two excess clauses by choosing a clear rule: when confronted with mutually repugnant excess or escape clauses, the loss must be prorated between the insurers in accordance with the policy limits.
See, e.g., Aid Ins. Co. (Mut.),
III. Application of the pro rata rule developed in the trilogy does not always accommodate the expectations of an insurer. Our rule is criticized because assignment of insurers’ relative responsibilities in the loss, being pegged to the dollar coverage provided, does not reflect the essential nature and scope of the risk contemplated in the policy. The trilogy cases involved confrontations between similar policies; all were automobile policies. In urging the Minnesota rule, Farm Bureau argues the rule from the trilogy eases should apply only when the policies purport to cover
*673
the same type of loss. There is some support for this position.
See Hastings Mut. Ins. Co. v. Auto. Ins. Co.,
780. F.Supp. 1153 (W.D.Mich.1991). Other courts have disagreed, upon finding “no meaningful basis” to conclude that one policy is more “specific” than the other.
See, e.g., Liberty Mut. Ins. Co. v. United States Fidelity
⅛
Guar. Ins. Co.,
The Minnesota court considered the “closer to the risk” rule more fair because it thought the coverage contemplated by the policies — and the premiums paid for them— should be the primary consideration in assigning the responsibility in this type of dispute.
See Interstate Fire & Cas. Co. v. Auto-Oumers Ins. Co.,
There is something to be said for the Minnesota rule, though we certainly did not subscribe to its approach in
Truck
where wé concentrated only on the effect of competing excess provisions in the policies.
Truck Ins. Exch.,
Clearness is a prime consideration in settling on a rule, though certainly not the controlling one. Simple fairness often demands a more complex application in preference to one more easily applied. We think it would be easier for the insurers to assess the risks and the appropriate premiums involved, than for the courts to process the disputes among the insurers under the “closer to the risk” doctrine.
We conclude the trial court erred in not applying the test enunciated in Truck. The two excess provisions are mutually repugnant, and the loss should be prorated between Illinois National and Farm Bureau. The judgment of the trial court must be reversed and the case remanded for entry of judgment accordingly.
REVERSED AND REMANDED.
