Mr. David Gunning:

There are two issues there, that is, inflation and supply of materials, which are undoubtedly related. We are certainly seeing increased global demand across a range of commodities with large price increases in these globally traded commodities. That has given rise to the ongoing volatility. There has undoubtedly been disruption to the supply of raw materials. Covid-19 and Brexit have given rise to reduced production capacity, factory shutdowns and disruption and delays in production. There has also been a depletion in inventories in those supply chains.
