Nortel CFO and executive vice president Peter Currie is resigning, effective April 30th. Nortel has fought accounting problems during the last seven years and continues to face regulatory probes in the U.S. and Canada as a result. Currie held many posts at Nortel during his tenure from 1979 to 1992. Currie returned to Nortel as finance chief from 1994 to early 1997 and then returned again as finance chief in 2005 following the completion of a major restatement. Nortel has begun the search for Currie's replacement.
