Among the most prominent unsolicited transactions was TotalFina's successful $54 billion offer for Elf Aquitaine, the largest offer ever in France. CSFB acted as principal advisor to TotalFina, which emerged victorious and thus became the world's fourth-largest oil and gas company. As Investment Dealers' Digest noted in naming the transaction its Energy Deal of the Year, "no other deal in 1999 provided as clear a microcosm of the transformation taking place in the rapidly consolidating international energy market." The transaction again demonstrated TotalFina's role as one of the industry's leading consolidators, with Total having acquired Petrofina earlier in the year (on which CSFB also advised).
