How long does it take for bonus shares to get listed after book close date

By Earnmoney.com.np on Apr 10, 2024

Can someone please tell me how long (on average) it takes to list the bonus share in nepsetms and mero share after the book close date?

For example, STC book close date was on 22nd Mar 2024 but I do not find the listing date anywhere.

Thank you.
