Homer Mooney appeals the district court’s 1 adverse grant of summary judgment in his Employment Retirement Income Security Act lawsuit against AT & T Umbrella Benefit Plan # 1 (the Plan) arising from the denial of long-term-disability (LTD) benefits. Upon de novo review of the record, we agree with the district court that the Plan did not abuse its discretion in denying Mooney’s claim for LTD disability benefits. See Dillard’s Inc. v. Liberty Life Assurance Co. of Boston, 456 *724 F.3d 894, 899 (8th Cir. 2006) (plan administrator’s decision will be reversed only if it was arbitrary and capricious; decision need be only reasonable, meaning it must be supported by substantial evidence); see also Norris v. Citibank, N.A. Disability Plan (501), 308 F.3d 880, 883-84 (8th Cir. 2002) (reviewing de novo district court’s application of abuse-of-discretion standard). Accordingly, we affirm, and we reject as meritless Mooney’s arguments for reversal. See 8th Cir. R. 47B.
