 has considered the following concepts as part of the acquisition cost, as applicable:

(a) Accrued interest expenses during the construction period that are directly attributable to the acquisition, construction or production of qualifying assets, which are those that require a substantial period prior to being ready for use. The interest rate used is that related to the project’s specific financing or, should this not exist, the average financing rate of the investor company.

Financing costs are not capitalized for periods that exceed the normal term of acquisition, construction or installation of an asset, such as delays, interruptions or temporary suspension of the project due to technical, financial or other problems that prevent the asset from reaching a usable condition.

(b) The future costs that the Company will have to experience, related to the closure of its facilities at the end of their useful life, are included at the present value of disbursements expected to be required to settle the obligation and are recorded as a liability and its subsequent variation is recorded directly in results.

Having initially recognized provisions for closure and refurbishment, the corresponding cost is capitalized as an asset in “Property, plant and equipment” and amortized in line with the amortization criteria for the associated assets.

Construction-in-progress is transferred to property, plant and equipment in operation once the assets are available for use and the related depreciation and amortization begins on that date.

Extension, modernization or improvement costs that represent an increase in productivity, ability or efficiency or an extension of the useful lives of property, plant and equipment are capitalized as a higher cost of the related assets. All the remaining maintenance, preservation and repair expenses are charged to expense as they are incurred.

The replacement of assets, which increase the asset’s useful life or its economic capacity, are recorded as a higher value of property, plant and equipment with the related derecognition of replaced or renewed elements.

Gains or losses which are generated from the sale or disposal of property, plant and equipment are recognized as income (loss) and calculated as the difference between the asset’s sales value and its net carrying value.

The cost of interest is recognized by applying an average or average weighted interest rate for all financing costs incurred by the Company to the final monthly balances for works underway and comply with the requirements of the required standard.

#### 2.19

#### Depreciation of property, plant and equipment
Property, plant and equipment are depreciated through the straight-line distribution of cost over the estimated technical useful life of the asset, which is the period in which the Company expects to use the asset. When
