On September 15, 2025, the professionals for KS Mattson Partners and the Committee held a town hall which walked through how to complete the voluntary questionnaire and electronically submit a proof of claim. A recording of the Town Hall is available, with closed captioning, here: https://pszjlaw.zoom.us/rec/share/fBaUAsV8hCYtdxhAfOXUl0AjVYV2PPPAFtqMWW0uQoXUgXIIdyGP16P8zGA0suDt.hwpMyiQN101ujSks.

Since the Sixth Town Hall, the Committee has received several questions about: (i) how to complete the hard copy version of the proof of claim form, (ii) what to do if one’s files are too large to upload through the online claim portal, and (iii) when does one need a PIN / ID to submit their proof of claim and how to request one. To address these questions, we have recorded a brief informational presentation. The presentation is available here: https://pszjlaw.zoom.us/rec/share/-b62GiVe8O9Mx_LMpE0pgFsAo4Jko1-mYG04ryCYKZyZGOBwOS8juv8aE6cBKbhk.PmCg5SYKJ4HM8VW1.
