There's not much information, but THR has a short story reporting that Axium International, which is Hollywood's top payroll services firm, has shut down. Tax problems could be involved, but again there's not much to go by. Firms like Axium are responsible for providing payroll checks and benefits for lots of entertainment workers around town (they serve as a kind of facilitator for the studios and production companies). The Reporter story says employees were told via e-mail not to show up to work starting Tuesday. Defamer has some bits and pieces as well.
