Annual Benefit Accrual Reset

Does anyone know if there is a speacial task to reset annual benefit accruals?  My customer says their accruals were not reset last year at year-end.  Payroll is telling her that the benefits team needs to reset accurals before the first payroll run of the year, but that's a new one to me.  Anyone have any idea what process needs to be run for this?  I thought all acrruals were reset with the PR999.  Thanks in advance for your time.
