	"However, it must be remembered that the principal reason for calculating PPPs is the fact that when the prices of a given product are converted into a common currency unit using exchange rates, they are not in fact equal in all countries. The general leve l of prices tends to be systematically higher or lower in some countries than in others. Thus, a high or low XR price for an individual item in one country may be largely due to the fact that the general price level for that country is high or low when exc hange rates are used. It may not signal any abnormality in that particular price. For this reason, XR price ratios are less useful than PPP price ratios for validation purposes."<ref name="validation-tables" />{{rp\|9}}		{{quotation\|However, it must be remembered that the principal reason for calculating PPPs is the fact that when the prices of a given product are converted into a common currency unit using exchange rates, they are not in fact equal in all countries.
