2.1. Methodology for calculating NRVs
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

2.1.1. For each Member State and for each of the risk categories the NRV shall be calculated by applying in sequential order the following process:
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

2.2. Methodology for deriving CSTs from NRVs
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

2.2.1. For each of the risk categories, once the NRV has been calculated for each Member State according to the procedure laid down by section 2.1, the corresponding CST shall be assigned a value equal to the lower of:

2.3. Weighted averaging process for the calculation of NRVs
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

2.3.1. For each Member State and for each of the risk categories to which the weighted averaging can be applied according to point 2.1.1(c), the following steps shall be applied for calculating, during year Y (where Y = 2009 and 2011), the NRVY:
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

3. Framework model for the assessment of achievement of NRVs and CSTs

3.1. Methodology for assessing achievement of NRVs and CSTs
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

3.1.1. The following principles shall apply for assessing achievement of NRVs and CSTs:
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
3.1.2. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

3.1.4. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

3.1.5. The outcome of the assessment of achievement referred to in point 3.1.1 shall be classified as follows:
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

3.2.1. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

3.2.2. The first assessment step shall verify whether the observed safety performance is complying with the NRV or not. The observed safety performance shall be measured by using the measurement units listed in Appendix 1 and the data referred to in section 1.1, with time series which shall include the most recent years of observations as specified in section 3.1. The observed safety performance shall be expressed in terms of:
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

3.2.3. The second assessment step shall consider the safety performance as acceptable if the MWA does not exceed the NRV plus a 20 % range of tolerance. If this condition is not satisfied, the Agency shall ask the safety authority of the Member State concerned to provide the specifics of the single highest-consequence accident (in terms of FWSIs) in the most recent years of observation as referred to in section 3.1, excluding the years used to set the NRV.

3.2.4. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

3.2.5. The fourth assessment step shall verify whether the number of significant accidents per train-km, with respect to the previous years, remained stable (or decreased). The criteria for this appraisal shall be whether there has been a statistically significant increase in the number of relevant significant accidents per train-km. This shall be evaluated by using an upper Poisson tolerance bound which will determine the acceptable variability based on the number of accidents that occurred in the different Member States.

3.3. Moving weighted averaging process for the annual assessment of achievement of NRVs
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

3.3.1. For each Member State and for each of the risk categories to which the Moving Weighted Averaging (MWA) is applied for carrying out, in each year Y (starting from Y = 2010 onwards), the assessment steps described in section 3.2, the following phases shall be applied for calculating the MWAY:
