Thank you for your question.
At the peak, we were seeing about 30% of contracts having advance payments. That has obviously dropped off significantly as the market has settled, so contracts now are rarely seeing advance payments.
When we were at the peak of the shortage of supply, roughly 30% of contracts were requiring some sort of advance payment. The amount shifted as well. In the early days, it was 30%, and then in a matter of a week or two, it jumped to 50% and in some cases 100%. The market was very volatile at that time.
