SUMMARY ORDER
Plаintiff — Appellant Lantheus Medical Imaging, Inc. (“Lantheus”) appeals from a decision of the United States District Court for the Southern District оf New York (Failla, J.) granting summary judgment to Defendant — Appellee Zurich American Insurance Co. (“Zurich”) on an insurance coverage dispute that arose between the parties after Lantheus experienced a supply — chain disruption in late spring 2009. The supply — сhain disruption occurred due to a fifteen — month shutdown of a National Research University nuclear reactor (“NRU Reactor”) that forced Lantheus to suspend dozens of production runs for one of its products. Lan-theus sought coverage from Zurich for the resulting lоsses, but Zurich denied the claim.
“Insurance policies are, in essence, creatures of contract, and, accordingly, subject to principles of contract interpretation.” In re Estates of Covert,
“ ‘Where contractual language is ambiguous and subject to varying reasonable interpretations, intent becomes an issue of fact and summary judgment is inapрropriate. ... Only where the language is unambiguous may the district court construe it as a matter of law and grant summary judgment accordingly.’” Palmieri v. Allstate Ins. Co.,
When an insurance contract contains an exclusion provision, the insurer generally bears the burden of proving that the claim falls within the scope of an exclusion by establishing that “the exclusion is stated in clear and unmistakable language, is subjеct to no other reasonable interpretation, and applies in the particular case.” Vill. of Sylvan Beach v. Travelers Indem. Co.,
The District Court’s analysis is thorough and sound. From the outset, the District Court drew all inferences in favor of Lantheus, accepting that “the breach occurred because of a ‘pressure surge ... actftng] upon an already weakened pоint.’” Special App’x 28 (alterations in original) (quoting Pis. Opp. to Summary Judgment at 10). It specifically declined to resolve certain outstanding factual ambiguities that were not necessary to decide Zurich’s summary judgment motion, including whether “General Corrosion precipitated the NRU Reactor shutdown.” Special App’x 36. Honoring the anti — concurrent causation language of Exclusion 5b, the District Court found аs a factual matter (and based on agreement of both of Lantheus’s experts) “that a thinning over time of the aluminum wall of the reactor vessel, referred to as [redacted] Penetration, was a necessary component to the through — wall breach that occurred after a rapid shift in pressure.” Special App’x 29-30. The District Court then concluded as a legal matter that the definition of “corrosion” as used in Exclusion 5b “fully embraces” this condition, including Lantheus’s assertion that an electrochemical cell caused the [redacted] Penetration.
Lantheus argues that Exclusion 5b must be read as a whole and “generally connotes a process by which material is gradually consumed or worn away, either by external forces or the material’s own inherent qualities.” Appellant’s Br. 41; see also City of Burlington v. Indem. Ins. Co. of N. Am.,
We have considered all of the Appellant’s remaining arguments and find them to' be without merit. Accordingly, we AFFIRM the judgmеnt of the District Court.
Notes
. We review de novo a district court's grant of summary judgment. See Lynch v. City of New York,
. Before reaching these issues, the District Court determined as a threshold matter that it need not resolve thе issue of whether the contingent business income loss coverage ("CBI”) provision of the Policy required total cessation of the operations at the Billerica Facility before Lantheus could collect insurance from a covered loss. The District Court оbserved that "[i]n 2005, the Second Circuit observed that ‘CBI coverage is a relatively recent development in insurance law and its scоpe has not yet been fully delineated by the courts,' " Special App’x 23 (quoting Zurich Am. Ins. Co. v. ABM Indus., Inc.,
We need not resolve this novel issue to dispose of the present case. Like the District Court, we assume for purposes of this appeal that Lantheus is covered under the CBI provision but find ultimately that Exclusion 5b operates to foreclose coverage under the Policy.
