I don't think that would be a problem, just means
Opco is now public. Normally this type transaction is
called a "reverse shell". One other way to go public
other than an IPO is for a private firm to buy a public
firm/ or shell. Browning Ferris Industries (BFI) was a
reverse shell. It's a lot cheaper to go public as a
reverse shell than an IPO. Lawyers sell public shells for
anywhere from $80k and up.
