Article 27
Equity accounting of associated undertakings
When this Article is applied for the first time to an associated undertaking, that associated undertaking shall be shown in the consolidated balance sheet either:
at its book value calculated in accordance with the measurement rules laid down in Chapters 2 and 3. The difference between that value and the amount corresponding to the proportion of capital and reserves represented by the participating interest in that associated undertaking shall be disclosed separately in the consolidated balance sheet or in the notes to the consolidated financial statements. That difference shall be calculated as at the date on which that method is used for the first time; or
at an amount corresponding to the proportion of the associated undertaking's capital and reserves represented by the participating interest in that associated undertaking. The difference between that amount and the book value calculated in accordance with the measurement rules laid down in Chapters 2 and 3 shall be disclosed separately in the consolidated balance sheet or in the notes to the consolidated financial statements. That difference shall be calculated as at the date on which that method is used for the first time.
A Member State may prescribe the application of one or other of the options provided for in points (a) and (b). In such cases, the consolidated balance sheet or the notes to the consolidated financial statements shall indicate which of those options has been used.
In addition, for the purposes of points (a) and (b), a Member State may permit or require the calculation of the difference as at the date of acquisition of the shares or, where they were acquired in two or more stages, as at the date on which the undertaking became an associated undertaking.
