When securities subject to the capitalisation reserve are included in the portfolio, their actuarial rate of return is calculated taking into account the acquisition price, the probabilities, maturity dates and amounts, net of all taxes, of coupons, prizes and other ancillary benefits attached to these securities, and the redemption values.
For the bonds referred to in the second paragraph of article R. 343-9, the calculation is made by taking the initial redemption value multiplied by the ratio between the reference index on the date in question and the same index on the issue date of the security.
