Have you had a read of the "going concern" note in the 2016 preliminary report?I actually thought the same as you, that the company was just transporting livestock not trading it. it's not a complex business but the capital structure needs to be right. You can't scale up and you can't scale down quickly.
I'll take a wild guess that the animals are shipped once a letter of credit has been provided by the customer's bank.
Ouch.
