Which is where everything ends up. Polygram swallowed Pickwick, too.
Interestingly, Pickwick had a moment of legitimacy. They founded De-Lite Records as a subsidiary label and got hits from Kool & The Gang before selling De-Lite to Polygram.
That's an interesting twist! I can't think think of any other artists on De-Lite though, other than K&TG. That sounds like a label that Mercury would handle reissues for now (as it seem a lot of the R&B/funk ends up on Mercury).
