Now I used all my fingers and toes, but never got anywhere near your numbers.
TAP has $US 13m in cash, last report for 3 months said we had 5.3m increase for the 3 month period to March. Let's say, +5m till June, +5m till October, +5m till December, +5m till March 2019 is only $US 33m.
33 million / 426 million'ish shares = .077c US a share or about 10 cent AUD.
Remember I used fingers and toes.
