PROGRAMS BENEFITING COMMUNITIES

Social investment is a very significant topic to both Parex and its stakeholders, in particular to those communities located where the Company operates. We were able to identify this concern based on the feedback received through the many Company-fostered communication platforms where the most important community-related problems and needs are prioritized. We partner with public organizations because we want our social investment to have a greater impact on local development. Since the communities are actively engaged in the execution and monitoring of our projects, their participation creates a positive synergy for project sustainability.

In 2017, Parex made a social investment of approximately COP $11 billion (USD 3.4 million),in the areas where the Company operates. We amended the calculation base in relation to previous years since the Value Added Tax was removed and we included expenditures from January 1 to December 31, 2017.
