Calculation method for compound interest yields in the rating matrix

- Unit prices are calculated based on the reported values submitted from each designated reporting member. Compound interest yields are then calculated based on these Unit prices.
- Averages of these compound interest yields are posted in the table.

## Note3

Standard deviation calculation procedure

Standard deviation is calculated from the following formula with each compound interest yield of each reported data, the average of the compound interest yields calculated above and the number of reported data.

s2 = {(x1 – X）2 + (x2 – X)2 + ・・・ + (xn – X)2} ÷ (n – 1)

s : standard deviation・・・ calculating square root of s2

n : the number of reported data

x : each compound interest yield

X : average of compound interest yields

* Standard deviation is calculated to seven decimal places.

* In case that the number of reported data is only one, 0 is posted in the standard deviation columns.
