Starting with the release in April, the period of periodic revision of the price indexes (Corporate Goods Price Index, Input-Output Price Index of the Manufacturing Industry by Sector and Corporate Services Price Index) has changed from one year to one and a half years. The change is aimed at improving the accuracy of indexes.
The timing of scheduled revisions is kept unchanged. Revisions are made to the released indexes twice a year (in April and October, along with the release of the preliminary figures for the March and September indexes).
