James Marcum appeals the district court’s 1 adverse grant of summary judgment in his Employment Retirement Income Security Act lawsuit arising from the denial of early retirement disability benefits. Upon de novo review, see Green v. Union Sec. Ins. Co., 646 F.3d 1042, 1050 (8th Cir. 2011), we find no basis for overturning the district court’s well-reasoned determination that the adverse decision on Marcum’s benefits application did not amount to an abuse of discretion, see id. (affirmance is warranted if the decision is reasonable, i.e., reasonable person could have reached similar decision, given evidence before plan administrator when decision was made). The district court is affirmed. See 8th Cir. R. 47B.
