Federal 7th Circuit Court
Civil Court
ERISA
Dist. Ct. did not err in confirming arbitrator's decision that reduced by $1.093 million defendant-employer's withdrawal liability after defendant notified plaintiff-pension plan that it was no longer participating in said plan. Arbitrator could properly reduce defendant's withdrawal liability where: (1) said liability is based in part on applicable interest rate determined by actuary; (2) ERISA requires that computation of withdrawal liability be based on best estimate of actuarial assumptions; and (3) plaintiff had previously directed actuary to use rate other than actuary's best estimate of correct interest rate, which in turn, increased defendant's withdrawal liability by $1.093 million from amount it would have owed had actuary's best estimate of interest rate been used throughout applicable period.
