#### Basis of consolidation
(a) Subsidiaries

The Company established control as the basis of consolidation for its financial statements. The Company controls a subsidiary when it is exposed, or has rights, to variable returns from its involvement with the subsidiary and has the ability to affect those returns through its power over the subsidiary.

The consolidation of a subsidiary starts when the Group controls it and it is no longer included in the consolidation when control is lost.

Subsidiaries are consolidated through the line by line method, adding items that represent assets, liabilities, income and expenses with a similar content, and eliminating operations between companies within the SQM Group.

Results for dependent companies acquired or disposed of during the period are included in the consolidated accounts from the date on which control is transferred to the Company or until the date when this control ends, as relevant.

To account for an acquisition of a business, the Company uses the acquisition method. Under this method, the acquisition cost is the fair value of assets delivered, equity securities issued and incurred or assumed liabilities at the date of exchange. Assets, liabilities and contingencies identifiable assumed in a business combination are measured initially at fair value at the acquisition date. For each business combination, the Company will measure the non-controlling interest of the acquiree either at fair value or as proportional share of net identifiable assets of the acquire.
