Frankly, right now the biggest challenge is inconsistency and unpredictability. That's particularly problematic in terms of container shipping. That's normally the most predictable. Those are ships that normally run on a schedule. You know when they are arriving and you know where they going. The challenge now, particularly with some of the lockdowns that have taken place in China and the things that have happened previously, is that you're just not sure when things are going to arrive, and that leads to a level of congestion that is problematic. That causes ripple effects right through the whole supply chain.
At the moment, or over the months since our progressive recovery from the natural disasters, that has really been the biggest single challenge.
