Syngenta AG (SYT)

Contractual Obligations, Commitments and Contingent Liabilities

At December 31, 2004, Syngenta had the following contractual obligations to make future payments in the following periods:

Of the total financial debt, variable rate financial debt is US$876 million, US$453 million of which is due after more than one year and US$423 million of which is due within one year. The US$423 million of short-term debt is of a duration of between one and three months, and the contractual interest obligation of US$1 million in respect of this debt is included in the table above. There is no contractual obligation to renew this debt. The debt amount, and the interest payments associated with it, will vary over time according to Syngenta’s funding requirements and future interest rates.

Except for the provision for payments under onerous contracts described above, US$1,128 million of provisions for long-term liabilities shown in Syngenta’s consolidated balance sheet have not been included in the above table because the timing of their payment is not contractually fixed, and cannot be estimated with sufficient certainty within the context of the time periods in the table. This applies particularly to those amounts which are not expected to be paid during 2005. Note 21 to the consolidated financial statements indicates Syngenta’s estimate that US$258 million of long term provisions are expected to be paid during 2005, including US$17 million of onerous contract provisions which are included in the above table.

The supply agreements for materials which give rise to the unconditional purchase obligations are entered into by Syngenta to ensure availability of materials which meet the specifications required by Syngenta. Where suppliers have made significant capital investment, these agreements generally provide for Syngenta to pay penalties in the event that it were to terminate the agreements before their expiry dates.

The rules of Syngenta’s main Swiss pension fund commit Syngenta to contributing a fixed percentage of employees’ pensionable pay to the fund. Under the regulations which apply to Syngenta’s main UK defined benefit pension

fund, Syngenta must commit to pay contributions according to a schedule which it agrees in advance with the Trustees. The existing schedule requires payment based on a percentage of pensionable pay, plus a fixed amount over a fixed number of years to eliminate the deficit in the fund. This schedule was revised in 2004 to take account of the statutory actuarial valuation which was carried out in 2003. The expected contributions payable by Syngenta in 2005 to meet its commitments under the above arrangements are included in the amount of US$200 million given in the additional US GAAP disclosures for employee benefit plans in Note 33 to the consolidated financial statements. Because both commitments are expressed partly or wholly as fixed percentages of pensionable pay, and not, or not completely, as fixed amounts, they have not been included in the above table.
