The arbitrator did not award Weaver all of her claimed expenses and costs, because he did not award wage loss or all of her requested costs. Because the arbitrator did not exceed his power, the district court erred by vacating the award. State Farm acknowledges that overdue payments invoke a 15 percent interest penalty. Overdue payments shall bear simple interest at the rate of 15 percent per annum. Id. , subd.
Interest accrues on the overdue payments from the time of demand until payment.
See Streich v. American Family Mut. The arbitrator awarded 15 percent interest on the benefit payments that he implicitly found were overdue. Interest continues to accrue until State Farm pays the claim. We recommend that the district court review the confirmation of the award and the inclusion of the accrued interest. Reversed and remanded .
