69. Where the distribution of the ARS of member institutions of a DGS covers only a partial range …

Where the distribution of the ARS of member institutions of a DGS covers only a partial range of the possible ARS, instead of the full range from 0 to 100, the DGS may reflect that situation by deciding to apply a threshold ‘ γ ’ of the ARS higher than 0 and a threshold ‘ 𝛿 ’ lower than 100. In this case, an ARS smaller or equal to ‘ γ ’ should be assigned an ARW of ‘ 𝛽 ’ and an ARS higher or equal to ‘ 𝛿 ’ should be assigned an ARW of ‘ 𝛼 ’ . The corresponding enhanced formula is:

𝐴𝑅𝑊 𝑖 = 𝛽 ∗ ( 𝛼 𝛽 ) ( 𝐴𝑅𝑆 (𝛿−𝛾) 𝑖 −𝛾 )

Where:

0 < 𝛾 < 𝛿 < 100 ;

γ is the lower threshold of the ARS translating to the lowest ARW β ; and

𝛿 is the actual upper threshold of the ARS translating to the highest ARW α .
