What happened to Arthur Andersen's pensions?, both partners and staff?

What happened to Arthur Andersen's pensions? I heard rumours that the partners lost everything because their pensions were not ring-fenced (apparently, according to what I heard, it was blasphemy to suggest ring-fencing the pensions because it implied that AA might be able to go under at some point in the future, so nobody suggested it). Also, I heard that staff pensions were different, that they were protected. Is that true? Can somebody who knows please add a section in the main article about AA pensions? Thanks in advance. — Preceding unsigned comment added by Betathetapi545 (talkcontribs) 12:59, 18 March 2018 (UTC)
