The principal issue, before us is whether, under Montana law, the pollution exclusion in a commercial general liability policy excludes coverage for losses sustained as a result of the addition of a foreign substance to crude oil transported in a pipeline. We hold that it does not.
BACKGROUND
This action was brought by Enron Oil Trading & Transportation Co. (“Enron”) in Montana state court against the defendants, who were its excess insurers under a liability policy. Enron seeks indemnity for amounts it paid Ashland Oil Company (“Ashland”) in settlement of an action Ashland brought against Enron (formerly UPG, Inc.) and others. Ashland’s complaint in that action alleged that it had suffered losses — explosions and malfunctions of its pipeline — as a result of the injection of foreign substances, so-called “B-G mix,” by Enron and others into the pipeline carrying crude oil to Ashland Refinery.
The insurers removed the action pursuant to 28 U.S.C. § 1441(d) and 28 U.S.C. § 1330. Enron then moved for summary judgment and the insurers countered with a motion for judgment on the pleadings under Fed. R.Civ.P. 12(c). The insurers contended that coverage under their policies was barred, first, by the “pollution” exclusion, and second, by Montana’s public policy barring recovery by insureds of indemnity for intentional acts. The district court rejected the insurers’ first ground but granted their motion on the second ground. We have jurisdiction under 28 U.S.C. § 1291, and we affirm in part, reverse in part and remand.
DISCUSSION
I. Standard of Review
We review de novo a dismissal under Rule 12(c). McGann v. Ernst & Young,
II. Dismissal Under Fed.R.Civ.P. 12(c)
The district court found that Ashland’s complaint alleged a series of knowing and intentional acts, including misrepresentation,
We do not need to reach the issue of Montana’s public policy. “A district court will render a ‘judgment on the pleadings when the moving party clearly establishes on the face of the pleadings that no material issue of fact remains to be resolved and that it is entitled to judgment as a matter of law.’” George v. Pacific-CSC Work Furlough,
Enron’s complaint states a claim for breach of the insurance contract; it alleges coverage and refusal to indemnify in breach of the contract. The complaint in the underlying action shows that Ashland’s claims were not limited to the intentional wrongful acts to which the district court adverted, but also included claims for negligence and strict liability not barred by Montana’s public policy. Enron would be entitled to prove in this action that the settlement payment was, in whole or in part, attributable to the negligence and strict liability claims; it would be entitled to prove that the claims based on intentional acts were not factors — or were minor factors — in the settlement because they lacked merit. It was not required to allege in its complaint the evidentiary facts in support of its theory of recovery. See Fed. R.Civ.P. 8(a) (“A pleading ... shall contain ... (2) a short and plain statement of the claim' showing that the pleader is entitled to relief_”).
III. Application of the “Pollution” Exclusion
We next address the insurers’ further contention that they were entitled to judgment by reason of the pollution exclusion in the policy. According to Ashland’s complaint, Enron and others, wrongfully or negligently, injected B-G mix, a commodity of significantly lesser value, into the crude oil common stream of the Portal Pipeline. Ash-land alleged that Enron’s actions violated the Portal tariff and resulted in economic damage and property damage to Ashland’s refinery.
The policy under which Enron claims indemnity from the insurers contains the following limitation on coverage:
INDUSTRIES, SEEPAGE, POLLUTION AND CONTAMINATION CLAUSE This insurance does not cover any liability for:
(1) Personal Injury or Bodily Injury or loss of, damage to, or loss of use of property directly or indirectly caused by seepage, pollution or contamination, provided always that this Paragraph (1) shall not apply to liability for Personal Injury or Bodily Injury or loss of or physical damage to or destruction of tangible property, or loss of use of such property damaged or de*530 stroyed, where such seepage, pollution or. contamination is caused by a sudden, unintended and unexpected happening during the period of this insurance.
(2) The cost of removing, nullifying or cleaning-up seeping polluting or contaminating substances unless the seepage pollution or contamination is caused by a sudden, unintended and unexpected happening during the period of this insurance.
(3) Fines, penalties, punitive or exemplary damages.
This Clause shall not extend this Insurance to cover any Liability which would not have been covered under this Insurance had this Clause not been attached.
The insurers contend that this clause bars Enron’s claim for indemnification because the term “contamination” is unambiguous under Montana law and, in accordance with its plain meaning, the injection of B-G mix into the pipeline contaminated the oil because it was rendered “impure, less valuable and less useful.” See Duensing v. Traveler’s Cos.,
The interpretation of a contract is a matter of law. Augustine v. Simonson,
The principles governing the interpretation of insurance agreements are well-settled in Montana law. “An insurance policy clause is ambiguous when different persons looking at the clause in light of its purpose cannot agree upon its meaning.” Leibrand v. National Farmers Union Prop. & Cas. Co.,
Under Montana law, “Ambiguities in an insurance policy are construed against the insurer and exclusions or words of limitation in a policy must be strictly construed against the insurer.” Leibrand,
Given these principles, we conclude that Montana courts would hold that the pollution exclusion does not bar coverage of the claimed loss. The use of the words “seepage, pollution and contamination,” together with the specific exclusion of “the cost of removing, nullifying or cleaning-up seeping polluting or contaminating substances,” sends an unmistakable message to the reasonable reader that the exclusion deals with environmental-type harms. Even if a contrary in
Our conclusion is reinforced by the decisions of other courts. In Pipefitters Welfare Educ. Fund v. Westchester Fire Ins. Co.,
The judgment is affirmed in part and reversed in part, and the matter remanded for further proceedings consistent with this opinion.

. "B-G mix” is butane-natural gas mix, also known as "indirect liquids.”
. On remand, the district court may conclude that under Montana law the burden of proof of circumstances excluding coverage is on the insurers. See Terry v. National Farmers Union Life Ins. Co.,
