RE:Book value of TV
In April/May 2019, the Zn was at 1.36 (it also went from 1.36 from August/17 to June/18), and the book value was 0.60.
You have to take note that TV has had to deteriorate assets in 2018 and 2020 (2 or 3 times). This decreases the book value, and TV will probably have to do the reverse. This improves the book value, therefore it would improve the Financial Statements.
