| (1) | The proven and probable reserves set forth in the tables above are shown before losses related to exploitation and mineral treatment. Proven and probable reserves are affected by mining exploitation methods, which result in differences between the estimated reserves that are available for exploitation in the mining plan and the recoverable material that is finally transferred to the leaching vats or heaps. The average mining exploitation factor for our different mines ranges between 80% and 90%, whereas the average global metallurgical recoveries of processes for nitrate and iodine contained in the recovered material vary between 55% and 65%. |

|-----|-------------------------------------------------------------------------------------------------------------------------------------------------------|

| (3) | Probable reserves can be expressed as proven reserves using a conversion factor. On average, this conversion factor is higher than 60%. This factor depends on geological conditions and caliche ore continuity, which vary from mine to mine. The difference between the probable reserve amounts and the converted probable reserve amounts is the result of the lower degree of certainty pertaining to probable reserves compared with proven reserves. |

| - | Cash equivalents approximate fair value due to the short-term maturities of these instruments. |
|---|------------------------------------------------------------------------------------------------|

| - | Other current financial liabilities are considered at fair value equal to their carrying values. |
|---|--------------------------------------------------------------------------------------------------|

| - | For interest-bearing liabilities with an original maturity of more than a year, fair values are calculated by discounting contractual cash flows at their original current market with similar terms. |
|---|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| - | For forward and swap contracts, fair value is determined using quoted market prices of financial instruments with similar characteristics. |

| (1) | Assets for the exploration or evaluation of mineral resources are amortized to the extent that the explored or evaluated area has been exploited. For this purpose, a variable rate is applied to extracted tons, which is determined based on the measured initial reserve and evaluation cost. The Company presents expenses associated with Exploration and Evaluation of Mineral Resources.  Of these expenses, those that are under exploitation are included under Inventory and are amortized according to the estimated ore reserves contained, and expenses associated with future reserves are presented under Other non-current assets.  Those expenses incurred on properties with low ore grade that are not economically exploitable are directly charged to income. As of December 31, 2010 balances associated with the exploration and assessment of mineral resources are presented under Inventory for ThUS$ 1,723 (ThUS$ 2,285 as of December 31 2009, and ThUS$ 1,421 as of January 01 2009). |
