I take it, you have never run a business, correct? I also take it that you are not an accountant, correct?
If you had these experiences you would have correctly interpreted the statements as value throughput and not cashflow. Of course, there may be some cash flow in March as we did have dredges operating prior to then and we may have had some material processed, exported and sold, but, that would be coincidental.
Again, the astute investor is looking for throughput, yield and capacity numbers as this is the only way to predict the capabilities of the company.
