Which document extends an invitation to creditors to form a committee during the administration process?

The Statement of Proposals plays a crucial role during the administration process of a company, particularly with respect to engaging its creditors. This document is prepared by the administrator and outlines how the company intends to deal with its financial difficulties. Importantly, it serves as an invitation for creditors to come together and form a committee.

The formation of this committee is vital as it allows creditors to have a structured platform to communicate with the administrator, share their insights, and contribute to the decision-making process regarding the company's future. This collaboration can help ensure that the interests of the creditors are represented effectively and that any proposed arrangements facilitate the best possible outcome for all parties involved.

In contrast, the other options refer to different aspects of business law and administration. An Administrative Receiver relates to a particular form of enforcement action taken by a secured creditor, a Moratorium is a temporary halt on debt enforcement, and Liquidation refers to the process of closing down a company and selling its assets. None of these options specifically involve the invitation to creditors to form a committee, making the Statement of Proposals the correct choice.
