NEW YORK ( TheStreet) -- American Eagle Outfitters ( AEO) announced on Tuesday that it is shuttering its Martin + Osa concept. This should come as a relief to American Eagle investors, as Martin + Osa has been a drain on American Eagle's business since its inception. In 2009 it recorded a loss of about $44 million. American Eagle will now focus on its namesake concept, aerie, and children's brand 77kids. All 28 Martin + Osa stores will close, as well as its online business -- moves that should be completed by the end of the year. -- Reported by Jeanine Poggi in New York.
