The amount of the gains mentioned in Article 124 B is set in accordance with the conditions set out in the first paragraph of 1 and 2 of Article 150-0 D. However, the costs of acquisition for valuable consideration may not be determined on a flat-rate basis.
For the determination of net gains from the sale of bonds or contracts mentioned in I of article 125-0 A, the acquisition price is determined by taking into account the premiums paid by the seller on the bond or contract sold and which have not been the subject of a capital repayment on the date of the sale. The fourth paragraph of the same I does not apply to these gains.
Losses incurred on disposals as defined in article 124 B may only be offset against income and gains withdrawn from disposals of securities or contracts whose income is subject to the same tax regime during the same year and the following five years.
