Osmo,

It does not work that way.

The Monitor is required to appoint a Claims Officer that by law manages the distribution of the estate's assets based on priorities as set forth in the reorganization or liquidation plan.

When Shareholders are involved, the Claims Officer will seek claims validation through the most effective and secured way to so. It can be done through the company's share registry and the Central Securities Deposit (CSD) in the U.S. and Canada and any other  countries where the shares were listed. From Nov. 1, 2019 the Canadian Business Corporation Act requires the Canadian Companies to keep a detailed register with the investors' stake in the company. So, one way or another, the Claims Officer will know who the shareholders are and how to locate them.

If for any reason a shareholder entitled to a claim cannot be reached, the Claims Officer will be required to deposit the value of the claim on his/her behalf with a court where the shareholder can claim it when the claims distribution process is completed.
