As of 2021-03-31

The following ESG scores are computed for the funds, using weighted average of the
funds' own "ESG Rating in Percent vs Traditional Benchmark" information (see factsheet).

Score quantification: [0, 1, 2, 3, 4, 5, 6] = [CCC, B, BB, BBB, A, AA, AAA]

Why not using the Fund's ESG rating, when declared? 2 reasons

1) I did not trust it. Some funds have score = AA when >50% of the allocation weight is on A or BBB
2) To make comparisons numerically consistent.

Re-calculated fund scores:

Fund ID         Score       Calculation
CH0240440187    3.96    =   6.6 * 6/10      # 6.6 is the ESG score as quantified in the fund's factsheet
LU0803003796    3.42    =   5.7 * 6/10      # 5.7 is the ESG score as quantified in the fund's factsheet
CH0118503355    4.44    =   7.4 * 6/10      # 7.4 is the ESG score as quantified in the fund's factsheet
LU0141249424    # not available

Based on the scores above, the fund's ESG score is:

Weight = Allocation
Weighted score = Score * Weight
Total ESG score = sum(weights) / Covered weight
Total score % = Total ESG score / 6     # mapping [0, 1, 2, 3, 4, 5, 6] = [CCC, B, BB, BBB, A, AA, AAA]
