Bayer Leverkusen's corporate origins, however, are far from unique. Other clubs, including PSV, Carl Zeiss Jena and Sochaux, share a similar reputation of being works teams. As distinguished from the various Red Bull teams (Salzburg, New York and Leipzig) which has been established or redefined in the recent past primarily for commercial reasons, the formation of Bayer Leverkusen was motivated by the idea of promoting the living conditions of local factory workers early in the 20th century. In view of this tradition, UEFA allows Bayer Leverkusen to use the brand name Bayer in European club competitions while disallowing such naming practices most notably to Red Bull Salzburg.
