22.1

(a)

General information:

The amount of each item presented in each operating segment is equal to that reported to the highest authority that makes decisions regarding the operation, in order to decide on the allocation of resources to the defined segments and to assess its performance.

These operating segments mentioned are consistent with the way the Company is managed and how results will be reported by the Company. These segments reflect separate operating results that are regularly reviewed by the executive responsible for operational decisions in order to make decisions about the resources to be allocated to the segment and assess its performance (See Note 22.2).

The performance of each segment is measured based on net income and revenues. Inter-segment sales are made using terms and conditions at current market rates.

(b)

Factors used to identify segments on which a report should be presented:

The segments covered in the report are strategic business units that offer different products and services. These are managed separately because each business requires different technology and marketing strategies.

(c)

Description of the types of products and services from which each reportable segment obtains its income from ordinary activities

The operating segments, which obtain income from ordinary activities, generate expenses and have its operating results reviewed on a regular basis by the highest authority who makes decisions regarding operations, relate to the following groups of products:

(i)

Specialty plant nutrients

(ii)

Iodine and its derivatives

(iii)

Lithium and its derivatives

(iv)

Industrial chemicals

(v)

Potassium

(vi)

Other products and services

(d)

Description of income sources for all the other segments

Information regarding assets, liabilities, profits and expenses that cannot be assigned to the segments indicated above, due to the nature of production processes, is included under the "Unallocated amounts” category of the disclosed information.

(e)

Description of the nature of the differences between measurements of results of reportable segments and the result of the entity before the expense or income tax expense of incomes and discontinued operations

The information reported in the segments is extracted from the Company’s consolidated financial statements and therefore there is no need to prepare reconciliations between the data mentioned above and those reported in the respective segments, according to what is stated in paragraph 28 of IFRS 8, "Operating Segments".

For the allocation of inventory valuation costs, we identify the direct expenses (can be directly allocated to products) and the common expenses (belong to coproduction processes, for example common leaching expenses for production of Iodine and Nitrates), Direct costs are directly allocated to the product and the common costs are distributed according to percentages that consider different variables in their determination, such as margins, rotation of inventories, revenue, production etc.

The allocation of other common costs that are not included in the inventory valuation process, but go straight to the cost of sales, use similar criteria: the costs associated with a product or sales in particular are assigned to that particular product or sales, and the common costs associated with different products or business lines are allocated according to the sales.

(f)

Description of the nature of the differences between measurements of assets of reportable segments and the Company´s assets

Assets are not shown classified by segments, as this information is not readily available, some of these assets are not separable by the type of activity by which they are affected since this information is not used by management in decision-making with respect to resources to be allocated to each defined segment. All assets are disclosed in the "unallocated amounts" category.

(g)

Description of the nature of the differences between measurements of liabilities of reportable segments and the Company’s liabilities

Liabilities are not shown classified by segments, as this information is not readily available, some of these liabilities are not separable by the type of activity by which they are affected, since this information is not used by management in decision-making regarding resources to be allocated to each defined segment. All liabilities are disclosed in the "unallocated amounts" category.
