The depreciable securities listed in 1°, 2°, 2° bis and 2° ter of Article R. 332-2, other than bonds and index-linked units, units in debt securitisation funds and profit participation certificates, are recorded at their purchase price excluding accrued interest at the date of acquisition. The procedures for determining this purchase price, for amortising the difference between the purchase price and the redemption price over the residual life of the securities, and for recognising impairment in the balance sheet when it is considered that the debtor will not be able to meet its commitments, either for the payment of interest or for the repayment of the principal, are defined in a regulation issued by the Autorité des normes comptables (French accounting standards authority).
This article also applies to bonds indexed to the general price level of a country or group of countries whose currency is the currency in which the bonds are denominated, with a guarantee of repayment at par. These bonds are either issued by a private legal entity whose registered office is located within the territory of a Member State of the Organisation for Economic Co-operation and Development and traded on a recognised market, or issued or guaranteed by a State, public body or local authority mentioned in 1° of A of article R. 332-2, or those whose debtor is a national public institution of one of the Member States of the European Union.
By way of derogation from the provisions of the preceding paragraphs, bonds convertible into shares, when they present a negative actuarial rate on purchase, this rate being calculated without taking into account the exercise of the option, may be accounted for in accordance with article R. 343-10.
