OPINION
Appellants Cargill, Inc., and Cargill Turkey Production, L.L.C. (collectively Car-gill), sought a declaratory judgment in Hennepin County District Court against approximately' 50 insurance companies. Cargill claimed that each of its insurers has an obligation to defend and indemnify Cargill in lawsuits brought in Oklahoma and Arkansas alleging environmental contamination. Respondent Liberty Mutual Insurance Company filed a counterclaim against Cargill, and cross-claims against several of Cargill’s other insurers, seeking a declaration that Liberty Mutual would have subrogation or contribution rights from the other insurers for defense costs.
Cargill moved for partial summary judgment as to Liberty Mutual’s duty to defend Cargill; but the district court denied Cargill’s motion and granted partial summary judgment for Liberty Mutual. The court declared that Liberty Mutual has the right to seek contribution for defense costs from any insurer that has a duty to defend Cargill for the claims in the underlying litigation, and that costs of defense would be apportioned equally among such insurers. But the district court certified the following question for appellate review: “Can a court order primary insurers, who insure the same insured for the same risks, and whose policies are triggered for defense purposes, to be equally liable for the costs of defense where there is otherwise no privity between the insurers?” The court of appeals answered the question in the affirmative.
Cargill, Inc. v. Ace
*344
Am. Ins. Co.,
The State of Oklahoma sued Cargill in 2005 under the Comprehensive Environmental Response, Compensation, and Liability Act, 42 U.S.C. §§ 9601-9628 (2000), and the Solid Waste Disposal Act, 42 U.S.C. § 6972 (2000), alleging that Car-gill’s poultry waste disposal practices polluted and damaged land and water in the Illinois River Watershed. Cargill was also named as a defendant in a number of lawsuits in Arkansas alleging personal injury and wrongful death as a result of exposure to allegedly contaminated poultry litter.
Cargill notified its liability insurers of the Oklahoma and Arkansas litigation, requesting that the insurers defend and indemnify Cargill. Liberty Mutual agreed to pay its share of the reasonable and necessary defense costs in conjunction with Cargill’s other insurance carriers for the Oklahoma and Arkansas lawsuits, subject to a complete reservation of rights, deductible provisions, and all other policy terms and conditions. 2 But because none of Cargill’s insurers agreed to fully defend Cargill or pay defense costs without contribution from other insurers, Cargill chose to defend itself in the Oklahoma and Arkansas lawsuits.
In February 2007 Cargill filed a complaint in Hennepin County District Court seeking declaratory judgment and other relief against approximately 50 insurance carriers with whom Cargill had liability policies in effect, at some point, from 1957 to 2006. 3 Cargill asked the district court to declare that each insurer has a duty to provide a complete and undivided defense in the Oklahoma and Arkansas lawsuits and that each insurer has a duty to indemnify Cargill. 4 Liberty Mutual counterclaimed against Cargill, asking that the district court require Cargill to enter into a loan receipt agreement or to create such an agreement. In addition, Liberty Mutual filed cross-claims against several of Car-gill’s other insurers, asking the court to declare that Liberty Mutual had subrogation or contribution rights against these other insurers. Recognizing that the insurers’ duty to indemnify depended on the resolution of the underlying lawsuits in Oklahoma and Arkansas, the district court decided to divide the lawsuit into two phases and to address the insurers’ duty to defend in the first phase.
*345 In May 2007 several of the insurance companies, including Liberty Mutual, offered to pay Cargill’s reasonable and necessary defense costs in the underlying actions, subject to the insurers’ respective reservation of rights, and contingent on Cargill executing a loan receipt agreement. 5 Cargill refused to enter into a loan receipt agreement with the insurers. In October 2007 Liberty Mutual sent Cargill a check for partial payment for past defense costs, but again required that Cargill execute a loan receipt agreement. Under the proposed agreement, Liberty Mutual offered to pay Cargill’s defense costs in the underlying actions if Cargill permitted Liberty Mutual to seek recovery of defense costs from other insurers that are determined to have a duty to defend Car-gill. Cargill refused to enter into the loan receipt agreement with Liberty Mutual and returned the check. Cargill was concerned that it would have to bear part of the defense costs because, according to Cargill, some of Cargill’s primary or lower-level insurance policies (“fronted policies”) acted “merely as a retention or deductible, and do not provide Cargill with any economic risk transfer of defense costs to the primary insurer.” 6 Cargill alleges that some of these policies are in place to trigger umbrella and excess policy coverage. These fronted policies allegedly provide no defense costs coverage to Cargill because of retrospective premiums that were calculated to equal the losses paid, reinsurance of losses by a captive Cargill insurer, and high deductibles that match policy limits, thereby potentially subjecting Cargill to bearing part of the defense costs.
In November 2007 Cargill moved for partial summary judgment as to Liberty Mutual’s duty to defend based on a single comprehensive general liability policy that was in effect from June 1969 to June 1972. Cargill asked the district court to declare that:
1. Cargill can select Liberty Mutual to exclusively and fully defend it in the underlying lawsuits;
2. Liberty Mutual cannot obtain contribution from Cargill or other insurers *346 without a loan receipt agreement with Cargill;
8. Cargill has no obligation to enter into a loan receipt agreement with Liberty Mutual; and
4. Liberty Mutual cannot recover defense costs from Cargill, directly or indirectly.
Liberty Mutual filed a cross-motion for summary judgment, asking that the court require Cargill to enter into a loan receipt agreement, or that the court create such an agreement, or that the court declare that such an agreement is not necessary in order for Liberty Mutual to seek contribution of defense costs from other liable insurers.
While these motions were pending, Car-gill proposed a revised loan receipt agreement to Liberty Mutual, under which Liberty Mutual would agree not to make a claim for defense costs against Cargill or its subsidiaries. Cargill further proposed that Liberty Mutual indemnify Cargill against claims that other insurers may make against Cargill in connection with Liberty Mutual’s attempts to seek contribution from other Cargill insurers. Liberty Mutual did not accept Cargill’s proposed loan receipt agreement.
The district court ruled that Liberty Mutual has the right to seek contribution for defense costs from any other insurer who is determined to have a duty to defend Cargill in the underlying lawsuits, and the costs are to be shared equally among such insurers. The district court noted that Liberty Mutual did not deny its own duty to defend, but wanted all primary insurers to share defense costs. Because Liberty Mutual did not have privity of contract with the other insurers, the court determined, based on our ruling in Iowa National, that Liberty Mutual needed either a loan receipt agreement with Cargill, or a court order requiring that costs be shared by the insurers. The court concluded that Cargill’s refusal to sign a loan receipt agreement with Liberty Mutual was “because Cargill is concerned that would expose Cargill to claims that it is obligated to pay a share of defense costs to the extent that Cargill utilized ‘fronted policies.’ ” This was inequitable, according to the court, because
Cargill, a sophisticated business entity, has created this insurance structure, and it seems inequitable that they should now be permitted to avoid cooperating with Liberty Mutual (the insurer who[m] they have self-chosen to defend their liability claims) because of their concern that the insurance structure that they have created may have some adverse consequences to go along with the benefits they have received.
Therefore, the court declared that a loan receipt agreement was not necessary for Liberty Mutual to seek contribution for defense costs from other primary insurers. As an alternative, however, the court stated that it could impose a constructive loan receipt agreement between Liberty Mutual and Cargill. The district court then denied Cargill’s motion for partial summary judgment, and certified for appellate review the question of whether “a court [can] order primary insurers, who insure the same insured for the same risks, and whose policies are triggered for defense purposes, to be equally liable for the costs of defense where there is otherwise no privity between the insurers.” 7
The court of appeals answered the certified question in the affirmative.
Cargill,
*347
Inc. v. Ace Am. Ins. Co.,
The court of appeals dissent agreed with the majority that under the Iowa National rule, absent a loan receipt agreement, Liberty Mutual has no right to contribution from other insurers. Id. at 66 (Larkin, J., dissenting). But in contrast to the majority, the dissent concluded that the Liberty Mutual policy language does not require Cargill to enter into a loan receipt agreement, and the court should not write such a requirement into the policy. Id. at 68. Both parties petitioned for review of the court of appeals decision, and we granted review.
We apply a de novo standard of review because this case comes to us on petitions for review of the court of appeals’ determination of a certified question.
See Larson v. Wasemiller,
Cargill argues that under Iowa National, Liberty Mutual must provide a complete defense to Cargill and cannot pass part of that duty to other insurers. Cargill contends that Liberty Mutual is not entitled to recover from or have defense costs apportioned among other insurers in the absence of a loan receipt agreement or a waiver of the Iowa National rule by the insurers. In contrast, Liberty Mutual asserts that Iowa National is not applicable to this case because it is limited to situations where, unlike here, an insurer has already participated in the insured’s defense and then seeks contribution. Liberty Mutual also argues that Iowa National should be limited to situations involving concurrent policies triggered by a discrete injury, and does not *348 apply to successive policies triggered by a continuous occurrence.
In
Iowa National,
a vehicle owned by Mitchell Boyer, Inc., was involved in an accident.
We noted that there was no contractual privity between Iowa National and Universal that would make one insurer accountable to the other, and we reiterated that “[t]he obligation of defending an insured and paying for the defense is a separate obligation existing exclusively between the insurer and the insured.”
Id.
at 366-67,
After concluding that there was no contractual basis for Iowa National to seek defense costs from Universal, we rejected Iowa National’s claim for recovery based on the theory of contribution: “[T]he two companies have no joint liability or common obligation. Both were obligated to defend under separate contractual undertakings which would not support a common obligation for the purpose of invoking the principle of contribution.”
Id.
at 368,
Therefore, the general rule from
Iowa National
is that an insurer that defends or participates in the defense of an insured has no basis for seeking recovery of de
*349
fense costs from another insurer. We reaffirmed the
Iowa National
rule in
St. Paul School District No. 625 v. Columbia Transit Corp.,
It is true that the facts of Ioiva National are distinguishable from the facts here insofar as the insurer in Iowa National actually defended the insured, and here, no insurer has yet provided a defense or incurred defense costs. But curbing Iowa National’s applicability based solely on this principle would oversimplify the matter. The certified question from the district court, as well as Liberty Mutual’s claim on petition for cross-review, essentially asks us to determine not only whether Liberty Mutual currently has a right to have defense costs apportioned among other insurers when it has not paid any costs, but also whether Liberty Mutual would have a right to reimbursement or contribution from other insurers if it pays defense costs or defends Cargill.
The duty to defend an insured is contractual and is broader than the duty to indemnify.
Meadowbrook, Inc. v. Tower Ins. Co.,
But since
Iowa National
was decided, we have found several exceptions to it that have limited its applicability. In
Jos-tens, Inc. v. Mission Insurance Co.,
for example, we reiterated that, under
Iowa National,
if two insurers have primary coverage for a claim, the insurer who undertakes to defend the insured “is responsible for its own defense costs and cannot later seek reimbursement from the other.”
Jostens, Inc. v. Mission Ins. Co.,
Here, none of the exceptions to the Iowa National rule apply: there is no loan receipt agreement in place because the insured refuses to execute one, and the insurers have not agreed amongst themselves to waive the Iowa National rule. In this case, Liberty Mutual urges us to carve out yet another exception to Iowa National by limiting Iowa National to situations involving concurrent policies triggered by a discrete injury or to look to language in Jostens suggesting that even in the absence of a loan receipt agreement, we should apportion costs equally among co-primary insurers who have a duty to defend when no insurer has defended or provided defense costs. Before considering whether to create another exception to Iowa National or to adopt Liberty Mutu-aPs interpretation of some of our statements in Jostens, we first consider some of our previous statements in Jostens and the Iowa National rule itself.
In
Jostens,
we explained that an insurer assuming the defense of the insured “has no cause to complain [about the absence of monetary assistance from other insurers] because it is protecting its own interests and is only doing what it agreed and was paid a premium to do.”
Further, in
Jostens,
we held that “[i]f it is established that both insurers arguably had coverage at the time of the rejected defense tender, the insurers, as between them, shall be equally liable for the insured’s defense costs.”
In
Iowa National,
however, we rejected the notion that one insurer with a duty to defend the insured had a right to seek contribution from another insurer which also had a duty to defend the insured, citing
Hartford Accident & Indemnity Co. v. Anderson,
But in a situation such as the one presented here, where the claims against Car-gill extend beyond the period covered by any one insurance policy and pertain to co-primary insurers, we cannot say that any insurer that undertakes to defend Cargill in any of these lawsuits would be “answering for only his own just and proper share” of the defense. Rather, in this case Liberty Mutual has agreed to defend Cargill only with respect to claims of damages caused by “an occurrence,” that is, “an accident ... which results,
during the policy period,
in bodily injury or property damage.” (Emphasis added.) Cargill has notified insurers other than Liberty Mutual providing primary coverage, thereby also triggering their duty to defend if the underlying claims arguably fall within the respective policies’ scope of coverage.
See Wooddale,
From the time that Liberty Mutual received notification of the underlying lawsuits, it agreed to defend Cargill, but contingent on Cargill executing a loan receipt agreement, presumably because Liberty Mutual was aware that if it defended Car-gill or paid defense costs, Liberty Mutual would not have been able to recover any *352 defense costs from other insurers without a loan receipt agreement. If Liberty Mutual (or the other insurers) knew that Minnesota recognized an equitable right of contribution, and absent the Iowa National rule, we would likely not have this present case before us.
The
Iowa National
rule does little to encourage insurers to “resolve promptly the duty to defend issue.”
Jostens,
We conclude that the Iowa National rule, even as we have modified it over the years, is no longer an appropriate result when multiple insurers may be obligated to defend an insured. There is little incentive for any single carrier to voluntarily assume the insured’s defense. To the contrary, under Iowa National an insurer who voluntarily assumes the defense finds itself bearing the entire cost of the insured’s defense unless the insured enters into a loan receipt agreement. As this case demonstrates, that the insured will enter into a loan receipt agreement is by no means assured.
We are “extremely reluctant to overrule our precedent under principles of
stare decisis”
and “require a compelling reason” before overruling a prior decision.
State v. Martin,
Although some jurisdictions have held, as we did in Iowa National, that a primary insurer cannot obtain contribution 11 from *353 a co-primary insurer that refused to defend, these cases represent the minority view. 12 Most courts have held that an insurer has an equitable right, whether by contribution or subrogation, to recover defense costs, at least partially, when primary insurers also have a duty to defend a common insured; this has been described as “the better-reasoned view.” 13 Allan D. Windt, Insurance Claims and Disputes: Representation of Insurance Companies and Insureds § 10:3, at 199-201 (4th ed. 2001); see also 1 Rowland H. Long, The Law of Liability Insurance § 5.07[1], at 5-97 (2009) (“[A]n increasing number of courts recognize that it is unfair to require one insurer to bear the entire burden of defense costs.”); Douglas R. Richmond, Issues and Problems in “Other Insurance,” Multiple Insurance, and Self-Insurance, 22 Pepp. L.Rev. 1373,1426 (1995) (“The majority position sounds in equity, and indeed is supported by fairness and logic.” (footnote omitted)).
We conclude that a co-primary insurer’s right to contribution from other primary insurers that have a duty to defend is supported by public policy and is the better reasoned position. Again, our statements in
Jostens
suggest, contrary to our statements in
Iowa National,
that an insurer has some equitable right to have defense costs apportioned. Therefore, where more than one primary insurer covers the same risk and an insurer discharges a common obligation also belonging to another insurer, we conclude, contrary to
Iowa National,
that a right to equitable contribution should exist in these circumstances.
See, e.g., N. Ins. Co. of N.Y. v. Allied Mut. Ins. Co.,
Accordingly, we overrule Iowa National and hold that a primary insurer that has a duty to defend, and whose policy is triggered for defense purposes, has an equitable right to seek contribution for defense costs from any other insurer who also has a duty to defend the insured, and whose policy has been triggered for defense purposes.
Further, we note that the district court stated in its order that
Liberty Mutual has the right to seek contribution for defense costs from any other insurer who has a duty to defend Cargill for the claims asserted against Cargill in the underlying litigation [and that] [o]nce a determination is made regarding which insurers have a defense obligation, those insurers with such an obligation shall be responsible in equal shares for the cost of defense of those claims.
An equal share for costs of defense among co-primary insurers is consistent with our approach in previous cases.
Wooddale,
But breach of a duty to defend precludes application of an equitable right to contribution.
See Fred O. Watson Co. v. U.S. Life Ins. Co.,
Affirmed.
Notes
. This court has stated the rule from
Iowa National Mutual Insurance Co. v. Universal Underwriters Insurance Co.,
[W]here it can be argued, legitimately and in good faith, that either of two insurers has primary coverage for a claim, both insurers have a duty to defend that claim. If either insurer undertakes the defense, it is responsible for its own defense costs and cannot later seek reimbursement from the other.
Jostens, Inc. v. Mission Ins. Co.,
. Liberty Mutual notes in its brief, however, that it has not made an unqualified admission that there is coverage under its policies for the Oklahoma and Arkansas lawsuits.
. The record does not indicate when the damages alleged in the Oklahoma and Arkansas lawsuits first occurred.
. Cargill claims that it incurred approximately $5.4 million in total defense costs by February 2007. Liberty Mutual contends that because Cargill has not provided any defense cost bills to its primary insurers since February 2007, the total cost of defense in the underlying litigation is presently unknown to the insurers.
. Under a loan receipt agreement, an insurer makes a loan to the insured for defense costs, which the insured agrees to repay from amounts recovered from another insurer.
See Jostens,
. Although the precise arrangements of the fronted policies Cargill has in place are not entirely clear, "fronting,” in general, is a situation where "an insurer, for a fee, issues a policy with the intent of passing most or all of the risk back to the policyholder, or to an unlicensed reinsurer or captive insurer.” John F. O’Connor, Insurance Coverage Settlements and the Rights of Excess Insurers, 62 Md. L.Rev. 30, 47 n. 86 (2003) (citation omitted) (internal quotation marks omitted). Thus, fronted policies
are policies that have a deductible equal to the coverage available under the policy or require the policyholder to reimburse the insurer issuing the fronting policy for any amounts paid by the insurer under the policy. Similarly, policyholders sometimes create their own insurance company — called a captive insurer — to provide lower-level coverage solely to the policyholder and affiliated companies, with excess policies issued by noncaptive insurers applying over the limits of the captive insurer’s coverage. In any of these situations, the policyholder's incentive may be to characterize a series of claims against it as arising out of a single occurrence in order to exhaust the "coverage” provided by the primary policy so the policyholder can access more favorable coverage available under its excess policies.
Id. at 46-47.
. A district court may certify an issue for appellate review "if the trial court certifies that the question presented is important and doubtful, from an order ... which denies a motion for summary judgment." Minn. R. Civ.App. P. 103.03(1).
. In answering the certified question, the court of appeals framed the issue as follows:
When an insured maintains numerous insurance policies and insurance arrangements and the insured demands that one primary insurer pay all defense costs and refuses to cooperate with that insurer to preserve a full right to contribution, does a district court have the authority to fashion a remedy that will allow the primary insurer to preserve its claim for contribution for defense costs?
Cargill,
. At the time of the original lawsuit, the two insurers disputed which was the primary carrier and which provided excess coverage; based on policy language, we earlier determined that Iowa National was an excess insurer and Universal was the primary carrier.
See Lowry v. Kneeland,
. It is not clear in Jostens whether we held that the insurers should be equally liable for defense costs because there was a loan receipt agreement in place, or whether we apportioned costs equally without regard to the loan receipt agreement:
[W]e look at the situation as it was for Jostens at the time it was confronted with [the] allegations [ (i.e., before the loan receipt agreement) ]. Viewed from this standpoint it hardly seems fair Mission should now be responsible for the entire costs simply because Jostens has selected *350 Mission rather than Wausau to pay them. Who should pay the insured’s defense costs should not depend on the whim or caprice of the insured, when, at the time the defense was needed, both insurers arguably had a duty to defend.
. Equitable contribution may be defined as
the right to recover, not from a party primarily liable for the loss, but from a co-obligor or co-insurer who shares common liability with the party seeking contribution .... The right of contribution is not derivative of the rights of the insured, but belongs to each insurer independently to seek reimbursement from a co-insurer those sums which were paid in excess of an insurer’s proportionate share of the common obligation.
U.S. Fid. & Guar. Co. v. Federated Rural Elec. Ins. Corp.,
. Courts that have not recognized an insurer’s right to equitable contribution from other insurers include the following: (1) Florida:
Cont’l Cas. Co. v. United Pac. Ins. Co.,
. Courts that have recognized an insurer’s right to contribution or right to have defense costs shared in some way include the following: (1) Alaska:
Marwell Constr., Inc. v. Underwriters at Lloyd’s, London,
. Although we recognize a co-primary insurer's right to equitable contribution, we continue to recognize that an insurer’s duty to defend is not triggered until the insured has provided the insurer "with notice of a suit and opportunity to defend.” See
Home,
. We are not suggesting that Liberty Mutual's actions did in fact constitute a breach of the duty to defend; that issue is not before us. We provide this instruction because in affirming the court of appeals, although on different grounds, we also clarify that an insurer seeking to exercise a right to equitable contribution may be precluded from doing so if the insurer breached a duty to defend the insured.
