The first one would be the volume and the ability to receive a lot of products quickly and efficiently.
We can look at the age of other key ports. They were built somewhere between 1972 and 2008. When you look at a port that was built in 1972 and see the size of the ships and how many containers they used to carry, the maximum size at the time was 2,500 containers. Today, the maximum size is 25,000. Our ports haven't been updated quickly enough.
There are plans for some of these ports to be upgraded from when they were originally planned, but not quickly enough to receive these ships that are completely differently sized. The efficiency would be a component of that.
