Here's an example why NVT has such high ROE. NVT classroom has 20 students and one teacher. Next yr same classroom has same teacher and 25 students.

Some big businesses only pay their suppliers 60 days after receipt of goods. Powerful model esp as Govt are streamlining student visa applications from 1st July.
