Need to know the difference between paid-un and paid-up capital. Tks.?

Answer 1

Some context would be helpful.

Unpaid or paid-up capital could mean a stock issue subscription that has brought money in for the company's capitalization, or not. This would be the result of an 'agreement in principle' or an 'agreement in fact'--someone says 'yes it is a good idea', and someone who says, 'here's my check.'
