The determination of the relevant risk-free yield curve referred to in Article R. 351-2 uses information derived from relevant financial instruments and remains consistent with this information. This determination takes into account the relevant financial instruments for maturities at which the markets for these financial instruments, like the bond markets, are deep, liquid and transparent. For maturities at which the markets for the relevant financial instruments or bonds are no longer deep, liquid and transparent, the relevant risk-free yield curve is extrapolated.
The extrapolated portion of the relevant risk-free yield curve is based on smoothly converging forward rates from a forward rate, or set of forward rates, for the longest maturities at which it is possible to observe the relevant financial instrument and bonds denominated, in a deep, liquid and transparent market, to the ultimate forward rate.
