Examine the variables included in the dataset: - - Company: name of the company (Pirelli or Competitor) ID: identifier of the primary measure Dimension: ESG classification of the primary measure (Economic, Social, or Environment) Primary measures: sustainability Key Performance Indicator (KPI) Reported value: absolute value of KPI Year: sustainability reporting year Units: unit of measure of KPI Index Reciprocal: it indicates whether reported value should be transformed into an index value or a reciprocal value Transform the variable Reported value in index (reciprocal) depending on whether an increase of the primary measure is perceived as increasing (decreasing) the value for the stakeholders.

Note: your values should be in the column Value (column I) Example: R&D expenses (an increase of the metric implies higher sustainability) index Accident Frequency Index (an increase of the metric implies lower sustainability) reciprocal For Index measures: = [cell with Reported value of Year X]/[cell with Reported value of Year 2018] For Reciprocal measures: = [cell with Reported value of Year X]/[cell with Reported value of Year 2018]
