UBS tax evasion controversies enabling tax avoidance. In February 2015, UBS announced that it was being investigated by the Office of the U.S. Attorney for the Eastern District of New York and the Securities Exchange Commission over new allegations that UBS facilitated tax evasion by its U.S. clientele. The focus of the investigation is the possible sale of bearer bonds. Bearer bonds are a type of unregistered security that provide a degree of anonymity to the owner as they can be transferred anonymously when held in paper form, thus enabling tax evasion as such transfers would allow the owner to conceal their financial assets.
