What is it: PS is used by all operating units for the operational reporting to Group and is a volumereference. The SKF volume reference is a value based measurement. There are two elements of the SKFvolume reference, the cost element PS and the fixed translation rates called the PS rates used fortranslating the PS cost element.Where is it used:The PS rate is used for setting PS/SC in EUR for all products in ProdMast and for translating financialfigures for operational follow-up to SEK for analyses. Historical figures are recalculated in the Restatementprocess two years back in time and the current PS rate is used for translating the figures into SEK.Using the PS rate always means that despite which local currency is used we always arrive at the samevalue in SEK (or any other currency) for sales volumes and other volume measurements valued at PS,since the PS rate is fixed against all currencies.
