Aurora Publishing, child company of Japanese publisher Ohzora Shuppan. Aurora is a small, young publisher based in Torrance, CA (where the sales broker is also based) that has rather notoriously been selling its books off at dirt cheap prices for quite some time now, a move that now seems to have been a lead-up to an expected sale of the company.
There are other southern California-based publishers-- Go! Comi, based an hour off from Torrance and also awfully quiet of late; Seven Seas in Los Angeles, which just did some license rescues and is therefore probably not struggling all that much, and TOKYOPOP, which if nothing else has considerably more than two employees. So I'd join Simon and put my money on Aurora.
According to The Comics Reporter, Aurora is also about to lose its contract with digital manga/manhwa publisher Netcomics.com, who will be removing all Aurora manga from its site on April 14th-- which seems like another sign of a likely demise-- not to mention that attempts to reach Aurora have generally been in vain (the only phone number I've ever had for them is apparently disconnected, and as yet there has been no response to my e-mails).
It's rather fascinating: Aurora's focus was on the female market, publishing josei and yaoi titles. Yaoi fans in particular are widely credited with being better about buying than the average anime/manga fan in the US, but that doesn't seem to have helped Aurora much. On the other hand, their titles never seemed to get a lot of buzz, for all that some of them were quite good.
