Reconciliation of Non-GAAP measures to equivalent GAAP measures
Syngenta uses non-GAAP measures in this report where they are regarded by management as important for the investor to fully understand Syngentas performance. The non-GAAP measures presented in this report are measures adjusted for exchange rate movements and to exclude restructuring gains and losses and impairment losses. The Company presents these measures because:
Since Syngentas formation in November 2000, the Company has implemented significant business changes primarily designed to integrate and extract synergies from the now combined operations of the Zeneca agrochemicals business and the Novartis agribusiness. The effect on reported performance of initiating and implementing changes of this magnitude is significant and has had a material effect on the nature and focus of Syngentas operations through restructuring and impairment charges and therefore, in the opinion of management, requires separate disclosure to provide a more thorough understanding of business performance and to allow investors to assess performance both including and excluding charges, as well as gains, incurred in connection with these business changes. These business changes may also lead to the impairment of tangible (e.g. property, plant and equipment) or intangible assets. Impairment may also be triggered by a downturn in one of the businesses or markets in which Syngenta operates. The incidence of these charges may be periodic and the effect on reported performance will vary from period to period, with limited continuity in the specific composition or size of such charges.
For improved clarity, we are providing definitions of these non-GAAP measures and reconciliations of non-GAAP measures to the appropriate GAAP measure below.
