     Note: The seasonal factors shown in this table are for seasonal
     adjustments made directly to not-seasonally-adjusted Employment Cost
     Index series. Seasonal factors for remaining published seasonally
     adjusted series are not shown in this table because the series are
     seasonally adjusted indirectly; that is, as weighted sums of lower
     level component indexes. Specifically, all seasonally adjusted
     compensation series and remaining published wages and salaries and
     benefit cost series are derived indirectly.
