This excerpt taken from the SYT 20-F filed Mar 1, 2006.
Agroatar Agroatar S.A. on May 24, 2000 sued Zeneca S.A.I.C. (now Syngenta Agro S.A.) in Buenos Aires, Argentina for alleged wrongful termination of an agrochemicals supply contract. The plaintiff seeks damages for goodwill and loss of profits of US$43 million plus costs and interest. Agroatar has US$18 million debt outstanding to Syngenta but claims to be owed US$7 million by Syngenta under the terminated contract. On December 27, 1999, Agroatar S.A. filed a separate suit against Advanta Semillas S.A.I.C. which was amended on June 8, 2000 to include Zeneca S.A.I.C. (now Syngenta Agro S.A.) as a co-defendant. Agroatar alleges that Advanta Semillas S.A.I.C. breached its obligations under certain agreements which had originally been entered into with Zeneca S.A.I.C. (but which were subsequently assigned to Advanta Semillas S.A.I.C.) pursuant to which Agroatar had the rights to produce and sell sunflower, corn, and sorghum seed. Based on that alleged breach, Agroatar terminated the agreements. Agroatar claims damages of US$58 million plus costs and interest. The accumulated interest elements of these claims was estimated in mid 2005 as 45% of the principal amount if damages were awarded in US dollars or 150% if damages were awarded in Argentine pesos. In addition the court may award costs and expenses against the losing party of up to 25% of the damages including interest. The court may convert certain elements of the US dollar claim into Argentine pesos and, if so, would be likely to apply a conversion rate between 1:1 and the current market rate. Syngenta believes it had cause to terminate the agrochemicals supply agreement and was wrongly joined to the lawsuit against Advanta Semillas and intends to defend vigorously both lawsuits. The two lawsuits were consolidated in June 2001 and both are in the evidentiary stage, which is expected to be completed by mid 2006 and will be followed by filing of closing arguments by the parties. Judgement of the court of first instance in both lawsuits is expected in late 2006 or early 2007. Any appeal by the losing party(ies) to the Commercial Court of Appeal would take a further 1 to 2 years.
