CLAY, J., delivered the opinion of the court, in which COLE, J., joined. RYAN, J., concurred in the judgment only.
OPINION
Appellant, Northland Insurance Company (“Northland”) appeals from the district court’s orders granting appellee’s, Guardsman Products, (“Guardsman”) motion for summary judgment and denying Northland’s motion for summary judgment. For the reasons set forth below we AFFIRM the district court’s judgments.
*614 I. Statement of the Facts
Guardsman was a manufacturer of paints, lacquers, and other wood finish products; it had its principal place of business in Michigan. 1 In 1984, Guardsman negotiated with McAlear Associates (“McAlear”), an insurance broker also located in Michigan, to purchase insurance from Northland, a Minnesota company. McAlear had an agency agreement with Northland, thus, Guardsman ordered Northland’s insurance coverage through McAlear. McAlear billed Guardsman for the insurance premiums and Guardsman paid McAlear the required payment.
McAlear sold various Northland insurance policies to Guardsman for three years. The specific policy at issue in this case, is a products liability policy which covered the period from December 15, 1984 to December 15, 1985 and has a $550,000 limit of liability for each occurrence. In assessing whether to underwrite the products liability policy, Northland took into consideration the fact that Guardsman had manufacturing plants in several states, including California, and sold its products worldwide. Northland noted, however, that in assessing the risk “the manufacturing location is less relevant than where a product may be purchased, consumed, [and] distributed.” (J.A. at 472.)
The policy at issue provides, in relevant part, the following:
The company will pay on behalf of the insured all sums which the insured shall become legally obligated to pay as damages because of
A bodily injury or
B. property damage
to which this insurance applies, caused by an occurrence, if the bodily injury or property damage is included within the completed operations hazard or the products hazard, and the company shall have the right and duty to defend any suit against the insured seeking damages on account of such bodily injury or property damage____
(J.A. at 410.)
5. Other Insurance: The insurance afforded by this policy is primary insurance, except when stated to apply in excess of or contingent upon the absence of other insurance. When this insurance is primary and the insured has other insurance which is stated to be applicable to the loss on an excess or contingent basis, the amount of the company’s liability under this policy shall not be reduced by the existence of such other insurance.
(J.A. at 402.)
The policy also included a Certificate of Facultative Reinsurance and a Hold Harmless Agreement. (J.A at 417-420.) The reinsurance certificate was issued by G.C.I.; it requires Guardsman to pay a $50,000 self-insured retention (“SIR”) for each occurrence. Details Of Reinsurance Afforded is as follows:
TYPE OF INSURANCE ITEM 1 POLICY LIMITS & APPLICATION ITEM 2 REINSURER RETENTION ITEM 3 REINSURANCE ACCEPTED ITEM 4 BASIS OP ACCEPTANCE ITEM 5
Products Liability 550,000/700,000 Combined Single Limit 50.000 each occurrence 200.000 annual aggregate 100% of the limits as stated in Item 3 Primary coverage stated in Item 3
(J.A. at 417.)
Moreover, in the hold harmless agreement, Guardsman agreed “not to pursue against the Northland Insurance Company ... any claim or claims ... under or against or arising out of the first $50,000/200,000 occurrence/aggregate for Products Liability____” (J.A. at 419.)
In 1988, Guardsman was sued by CorryHiebert, a manufacturer of commercial office furniture products. CorryHiebert’s principal place of business is in California. CorryHiebert filed suit, in California district *615 court, on September 14,1988. CorryHiebert contended that beginning sometime in 1984, Guardsman sold and delivered defective lacquer to CorryHiebert’s California plant, and that CorryHiebert used the defective lacquer on its office furniture products. CorryHiebert alleged several claims, but only pursued claims for breach of express warranty, and breach of implied warranty. It sought damages for replacement costs, lost profits and loss of goodwill.
Prior to the filing, on August 4, 1988, Guardsman notified McAlear about the potential claim. McAlear sent notification to both Northland and ITT Hartford (“Hartford”), Guardsman’s insurance carrier prior to Northland. However, when the complaint was filed in September, it only alleged sales from September 1983 to November 1984, the period in which Guardsman was covered by the Hartford policy. Accordingly, Hartford retained counsel, in California, from the law firm Murchison & Cumming, to defend the suit.
Attorney Steven Smilay of Murchison & Cumming represented Guardsman in the CorryHiebert suit. It became apparent, during discovery, that some of the sales in question occurred during the Northland policy period. As a result, on May 17, 1990, Attorney Smilay notified Northland of its possible liability. Although it was sent this additional notification, Northland did not participate in the defense of Guardsman, opting instead to continue to monitor the case through the counsel retained by Hartford. On August 9, 1990, Northland sent a letter to Attorney Smilay informing him that Attorney Bryon Hollins was now assigned to monitor the CorryHiebert suit on behalf of Northland, and that all correspondence and information regarding the case should be sent to his attention.
On July 30, 1991, the district court dismissed, on summary adjudication, CorryHiebert’s damage claim for lost profits. Thereafter, in accordance to defense counsel’s recommendation, the parties agreed to submit the suit to arbitration before retired Judge Gerald J. Lewis. The agreement provided that CorryHiebert would be entitled to appeal the district court’s dismissal of the lost profits claim. On June 10, 1993, judgment was entered in favor of CorryHiebert and the amount of $480,882 was awarded for rework damages. CorryHiebert appealed the district court’s decision regarding the lost profits claim. In June 1994, Judge Lewis reinstated the lost profits claim finding that the district court erred in granting summary judgment.
Prior to the arbitration agreement, Guardsman asked for assurances from defense counsel that coverage would exist for the claims being submitted to Judge Lewis. On November 30, 1992, Attorney Smilay wrote to a Guardsman’s officer stating that the various insurance companies involved with this case approved the submission of the CorryHiebert suit to arbitration and that coverage should not be an issue. Northland was not identified as one of the carriers contacted by Attorney Smilay; however, a copy of the November 30, 1992 letter was sent to Attorney Hollins.
On the newly revived issue of lost profits, Guardsman, CorryHiebert, and the insurance carriers coordinated a settlement conference. Northland was invited to participate in the settlement negotiations. In a February 14, 1995 letter, Northland notified Guardsman that although it agreed to contribute $500,-000 to the settlement, it was reserving its right to recover the $500,000, stating that
[i]t is our belief that all claims with potential for coverage have already been disposed of and, further, that lost profits would not be covered by the Northland policy____ We reserve the right to file a Declaratory Relief Action to resolve the question of coverage which exists at this time, and any other coverage issues which come to light in the future.
(J.A. at 368-369.)
In April of 1995, Guardsman agreed to settle the lost profits claim by paying CorryHiebert $1 million—$50,000 of which would come from Guardsman pursuant to the SIR provision in the Northland policy; $500,000 from Northland; and $450,000 from American Empire.
After the settlement, Northland filed suit against Guardsman in the U.S. District Court *616 for the Central District of California seeking a declaratory judgment, reimbursement, and specific performance. The case was eventually moved to the Western District of Michigan pursuant to 28 U.S.C. § 1404(a). After discovery, both parties filed cross-motions for summary judgment. On September 25,1996, the cross-motions were heard before Judge Robert Holmes Bell. On October. 1, 1996, the court granted Guardsman’s motion and denied Northland’s motion, finding that North-land was estopped from denying coverage under the policy. On October 11, 1996, Northland filed a motion for reconsideration which was denied by the court on November 19, 1996. Northland filed a timely notice of appeal on December 18,1996.
II. Discussion
A. Standard of Review
‘We review the district court’s grant of summary judgment de novo, using the same standard as that used by the district court.”
Taylor v. Mich. Dep’t of Corrections,
Summary judgment is appropriate when ‘there is no genuine issue of material fact.’ Fed.R.Civ.P. 56(c). The moving party bears the initial burden of proving that no material facts exist, and the court must draw all inferences in a light most favorable to the non-moving party. A court may grant summary judgment when ‘the record taken as a whole could not lead a rational trier of fact to find for the non-moving party.’ Once the moving party has proved that no material facts exist, the non-moving party must do more than raise a metaphysical or conjectural doubt about issues requiring resolution at trial.
Agristor Fin. Corp. v. Van Sickle,
B. Choice of Law
Northland first argues that the district court failed to determine which state’s law governs the interpretation of the policy at issue. Specifically, Northland asserts that instead of the lower court referring, in its October 1, 1996, opinion, to both Michigan and California law without making a proper determination as to which state’s law controlled, the lower court should have concluded that California’s substantive law applied. Northland contends that if California’s law was applied by the lower court, its motion for summary judgment would have been granted, because pursuant to California law, lost profits does not constitute “property damage”. Thus, Northland asserts that the settlement was not covered under the policy, and therefore, it had no duty to pay. Because the outcome would have been the same under estoppel principles, regardless of whether the motion for summary judgment was decided pursuant to Michigan or California law, a choice of law determination is not necessary. However, we have taken it upon ourselves to make a determination.
We review the district court’s choice of law decision de novo.
MacDonald v. General Motors Corp.,
California has a statute that deals with choice of law conflicts arising out of the interpretation of contracts. Cal. Civ.Code § 1646. § 1646 states that “[a] contract is to be interpreted according to the law and usage of the place where it is to be performed; or, if it does not indicate a place of performance, according to the law and usage of the place where it is made.” It would appear, based on this statute, that Michigan’s law applies. Guardsman sold its products worldwide and had manufacturing plants throughout the United States, hence, the policy was to be performed in several places. However, the policy does not indicate one particular place of performance; thus, the law that governs is the law where the contract is made. Guardsman negotiated the policy with McAlear in Michigan, McAlear billed Guardsman for the insurance premiums in
*617
Michigan and Guardsman sent its payments to McAIear in Michigan. Clearly the contract was made in Michigan, therefore, it would appear that Michigan’s law applies. However, the California Supreme Court “has moved away from the mechanical application of § 1646. California now employs what is commonly termed the ‘governmental interest analysis’ approach to choice-of-law questions.”
Rosco, Inc., v. TIG Ins. Co.,
Under the governmental interest approach, “the forum in a conflicts situation ‘must search to find the proper law to apply based upon the interests of the litigants and the involved states.’ ”
Offshore Rental Co., Inc., v. Continental Oil Co.,
Accordingly, we must first determine what the law is in the respective states regarding the issue at hand; principally whether lost profits are, for purposes of the products liability policy, considered property damage. Because this is a diversity action, we must apply the law of the state’s highest court.
Clutter v. Johns-Manville Sales Corp.,
[i]f the highest court has not spoken, the federal court must ascertain from all available data what the state law is and apply it. If the state appellate court announces a principle and relies upon it, that is a datum not to be disregarded by the federal court unless it is convinced by other persuasive data that the highest court of the state would decide otherwise.
Id.
The Supreme Court of California has held that the word property, within the meaning of a casualty insurance policy, does not encompass lost profits.
Geddes & Smith, Inc., v. Saint Paul-Mercury Indem. Co.,
In thé case at hand, the policy has the above stated language; thus, pursuant to Michigan law, lost profits would be covered. Therefore, a conflict does exists between the two states. We must now examine whether either state has a legitimate interest in having its law applied.
California has a legitimate interest in having its law applied, since the injured party was a California resident, and the defective lacquer that caused the injury to the plaintiff was sold and delivered in California. Michigan as well has a legitimate interest in having its law apply; it wants to ensure that its insureds receive the benefit of their bargain. Here, the policy clearly states that North-land will pay “all sums which the insured shall become legally obligated to pay....” Michigan has interpreted this provision to include lost profits. Therefore, if California’s law applied, this coverage would be excluded.
*618 It is apparent that both states have a legitimate interest in having their law applied; henee, we are faced with a true conflicts case. We must therefore resolve this conflict by applying the law of the state whose interest would be the more impaired if its law were not applied. It would appear that California’s interest would be the more impaired; and thus, its law should be applied.
In the case at hand, the injured party, CorryHiebert, was a California resident, and the defective product was sold and delivered to CorryHiebert’s California plant. Under these circumstances, Guardsman and its insurers would reasonably expect that California’s law would apply.
See Stonewall Surplus Lines Ins. Co. v. Johnson Controls, Inc.,
Thus, lost profits are not covered by the policy. However, this fact, in and of itself, does not change the lower court’s holding that Northland was estopped from denying coverage under the policy; therefore, Guardsman’s motion for summary judgment was properly granted. See infra Part II.D.
C. Scope of Policy
Northland next argues, in the alternative, that Guardsman’s liability to CorryHiebert was for a claim not covered by the policy. Guardsman was found liable for breach of an implied warranty of fitness, a contractual claim. Northland asserts that its policy does not cover such claims. Thus, Northland contends that it is entitled to summary judgment, because like the lost profits claim, contractual claims are not covered under the policy, asserting that its policy with Guardsman only covers liability for torts. 2 We disagree.
Contract interpretation is a question of law subject to de novo review.
Golden v. Kelsey-Hayes Co.,
The policy in issue defines the term “products hazard” to include “property damage arising out of the named insured’s products or reliance upon a representation or warranty made at any time with respect thereto____” (J.A. at 622.) Moreover, the policy specifically states that warranties of fitness or quality are not excluded from coverage:
Exclusions
This insurance does not apply:
(a) to liability assumed by the insured under any contract or agreement; but this exclusion does not apply to a warranty of fitness or quality of the named insured’s products____
(J.A. at 631.) (emphasis added).
Thus it is clear from the plain language of the policy that liability for warranty of fit *619 ness is covered; and therefore, within the scope of the policy.
D. Estoppel
Finally, Northland contends that the lower court erred in holding that it was estopped from denying coverage for three distinct reasons: 1) Northland was an excess insurer under the policy and thus had no duty to earlier reserve its right; 2) Northland did not participate in Guardsman’s defense and owed no duty to defend Guardsman under the policy; and 3) there was no evidence of prejudice, and prejudice cannot be presumed. We hold that all of these claims are without merit; thus, the lower court properly granted Guardsman’s motion for summary judgment.
1. Primary Insurance
Northland contends that, as a matter of law, a primary policy is excess when it contains a SIR. Specifically, Northland argues that under the Details of Reinsurance Afforded, Item 5 refers to Item 3, the $50,-000 SIR, as primary insurance.
See supra
Part I. It asserts that, since Guardsman did not pay its required SIR payment of $50,000, until after it agreed to settle the lost profits claim, Northland’s reservation of right was timely, noting that it is not until a primary policy is exhausted that an excess insurer has a duty to reserve its rights.
See State Farm Fire & Cas. Co. v. Jioras,
General Star
does not apply to the case at hand. In
General Star
the court resolved the SIR issue by referring to the plain language of the policy. The SIR endorsement stated that “This Endorsement Changes the Commercial Liability Policy. Please Read It Carefully.”
Id.
at 1590,
This same clear wording is not found in the policy at hand. In the Northland policy, it states that “[t]he insurance afforded by this policy
is primary insurance, except when stated to apply in excess of
or contingent upon the absence of other insurance.” (J.A. at 402.) (Emphasis added). Upon review of the record, we find nothing in the policy to indicate that the Northland policy is to apply in excess. Moreover, there is nothing in the policy that eliminates Northland’s duty to defend. Nor does the GCI Certificate of Facultative Reinsurance, or the Hold Harmless Agreement, which Northland relies on, state that in the event of conflict in the policy, the SIR controls. Thus, when the language of a policy is clear and explicit, it must be given effect.
ACL Tech.,
2. Duty to Defend
Northland next argues that because its policy was excess, it had no duty to defend prior to payment of the SIR. Moreover, it asserts that the district court erred by concluding that it indirectly participated in Guardsman’s defense. Because we have already concluded that the Northland policy is primary, Northland had a duty to defend.
*620
An insurer’s duty to defend is broader than its duty to indemnify.
Val’s Painting & Drywall, Inc. v. Allstate Ins. Co., 53
Cal.App.3d 576, 585, 126 CaLRptr. 267 (Cal.Ct.App.1975). The duty to defend arises when an insurer “ascertains facts which give rise to the potential
of
liability under the policy.”
State Farm Mut. Automobile Ins. Co. v. Allstate Ins. Co.,
The Northland policy clearly states that Northland “shall have the right and duty to defend any suit against the insured seeking damages on account of such bodily injury or property damage....” (J.A. at 410.) CorryHiebert, sought damages for breach of express and implied warranty. As stated previously CorryHiebert’s claims for breach of warranty were within the scope of the policy, thus, Northland had a duty to defend. See supra Part II.C. Moreover, Northland became aware of the potential for liability in August of 1988 and May of 1990. In August of 1988, McAlear notified Northland of its potential liability. In May of 1990, North-land was again notified, this time by Attorney Smilay, of its potential liability; it was at this time, when it became apparent, that some of the sales in question were sold during the Northland policy. Therefore, because Northland had notice of potential claims, which were covered under the policy, in August of 1988 and May of 1990, its duty to defend arose, under the policy, at that time.
Northland contends, however, that even if it had a duty to defend, it did not defend the suit, and thus, the lower court’s finding that it indirectly participated in the defense was in error. We disagree.
It is true that Northland did not provide counsel for the underlying suit, instead, Northland opted to monitor the case through the counsel retained by Hartford. We hold that Northland’s decision to monitor the suit was, in essence, an indirect participation in Guardsman’s defense.
In general, the relationship between insurer and insured is a fiduciary one.
Shultz Steel Co. v. Rowan-Wilson, Inc.,
3. Prejudice
Northland’s final claim is that, even if its reservation of rights was untimely, estoppel still does not apply because there is no evidence that Guardsman was prejudiced in anyway, or relied to its detriment on North-land’s failure to reserve it rights. Based on the aforementioned, this claim must fail.
Before submitting the case to arbitration, the lost profits claim was dismissed. By remaining silent, Northland, in essence, consented to the terms of the agreement, which allowed the revival of the lost profits claim. If Guardsman knew that Northland would contest coverage, it might have postured the case very differently. Northland’s silence deprived Guardsman of the opportunity to fully assess its options, or the implications of Northland’s reservation of rights. Thus, we hold that Guardsman was prejudiced from Northland’s lack of notice.
See Stonewall
*621
Ins. Co. v. Palos Verdes Estates,
Northland also argues that estoppel cannot be used to create coverage, where coverage did not exist. Specifically, North-land contends that since, under California law, lost profits would not have been covered under the policy, estoppel cannot be used to force non-existent coverage. If an insured, however, reasonably relies, to his detriment, on an unconditional defense, an insurer can be estopped from raising coverage defenses.
Jioras,
In
Palos Verdes Estates,
the insurer defended the claims against its insured without asserting a reservation of rights.
Id.
at 1836,
Similarly in the case at hand, Northland entirely misses the point. As stated previously, Northland indirectly participated in Guardsman’s defense. Northland, however, did not assert a reservation of rights until some seven years after its knowledge of the lost profits claim. In accord with Palos Verdes Estates, we hold that such untimely notice operated as an inference of waiver as well as an inference of detrimental reliance. Consequently, Northland is now estopped from raising coverage defenses.
As it appears that all three contentions regarding the estoppel claim have failed, it was not improper for the lower court to grant Guardsman’s motion for summary judgment.
III. Conclusion
For the foregoing reasons we AFFIRM.
Notes
. Guardsman has been acquired by Lilly Industries, but for the purposes of this appeal I will continue to refer to appellee as Guardsman,
. Northland specifically argues that the policy’s language "legally obligated to pay as damages” has been interpreted by California courts to refer only to tort damages. In support of this contention, Northland has cited to various cases, including,
Chamberlain v. Allstate Ins. Co.,
However it should be noted that a products liability policy "usually covers hazards described as accidents arising out of the use of ... a
warranty
of products sold or distributed by the insured, with specified exclusions.”
