"In preparation for the second meeting, the voluntary administrator must send creditors the following documents at least five business days before the meeting:​

1. a notice of meeting
2. the voluntary administrator’s report, and
3. a statement about any proposals for a deed of company arrangement.

These will be accompanied by:​

1. a claim form (usually a ‘proof of debt’ form), and
2. a proxy voting form.

The meeting must also be advertised."
