PER CURIAM. Defendant-appellant Volvo Construction Equipment North America, Inc. appeals from the March 17, 2008, 542 F.Supp.2d 751,
summary judgment order of the district court, enjoining Volvo to continue providing fully-funded life insurance benefits to plaintiffs-appellees Isaac Rose and a certified class of similarly situated retirees, and to continue providing fully-funded health care insurance benefits to the class member retirees and eligible spouses and dependents. Having had the benefit of oral argument and having carefully considered the record on appeal, the arguments advanced by the parties in their briefs, and the applicable law, we are not persuaded that the district court erred in awarding
summary judgment to the plaintiff class members. In our opinion, Volvo’s core arguments are satisfactorily and properly answered within the four corners of the district court’s ruling. Insofar as Volvo now asserts arguments not first addressed to the district court, they are not properly before us and, in any event, are insufficient on their merits to undermine the integrity of the district court’s analysis.
Because we conclude that the reasoning which supports award of judgment to the plaintiff class members has been correctly articulated by the district court, issuance of a detailed written opinion by this court would be duplicative and serve no useful purpose. Accordingly, the judgment of the district court is, upon the reasoning employed in its opinion dated March 17, 2008, hereby AFFIRMED.
