I think you might need to tweak the playbook a bit.

I recall the structure of the hosts file we need to create, but I’m not sure if I included all the necessary variables in the template.

I’m a bit confused about the `when` condition in the playbook. Does it filter the hosts correctly for the dev group?

I think we did a similar question where we had to generate a config file using Ansible. It was about using the `template` module, right?

Okay, I think I've got this. I'll need to update the share capital and share premium accounts based on the new share issue details. Then I can recalculate the other equity balances.
