WASHINGTON (AP) - Abbott Laboratories says it repeatedly misstated the college education of senior executive Robert Gonzalez, who is soon slated to become CEO of its $18-billion-pharmaceutical spinoff.

Company filings between 2002 and 2007 state that Gonzalez received a bachelor's degree in biochemistry from the University of Miami and a master's degree in biochemistry from the University of Houston. The North Chicago, Ill., company's current website states that Gonzalez only attended those schools. The change was first reported by Crain's Chicago Business.

"There was an error made when the bio was written many years ago," says spokeswoman Melissa Brotz. "When we became aware of it we corrected it." Brotz says Abbott doesn't know when the incorrect information was introduced or corrected.

Abbott announced last October that Gonzalez would lead its spinoff AbbVie.
