You are right mate!
20% * 62.7% = 12.54%.
62.7% - 12.54% = 50.16% remaining...
That could be...
If we sell 12.54% * Mkt cap $15.17M can only obtain $1.9M (best offer @ current SP)
$1.9M + $0.8M (cash we had @ Dec 31st) totals only $2.7M (and we need > $3.2M to reach March 31st)
Or am I wrong again?
