Having assigned the weights for countries, we need a method to translate the fractional country and activity weights into the number of companies. It is performed in the following manner:
-
Country weights are multiplied by the size of the index (i.e., 2000 for the private2000), and the resultant numbers are rounded down to their closest whole integers.
-
Assign the number of companies to each country according to the number obtained in the first step.
-
Rank the difference between the country weight times 2000 and the rounded-down number.
-
Assign companies successively, starting from the largest difference and proceeding iteratively till 2000 total companies is reached.
-
For PECCS™ activity weights, starting with the country-activity weights, repeat the same procedure as indicated in Steps 1 to 4 for each country, but instead of starting with 2000 begin with the number of companies assigned in steps 1-4.
