In 2002, Progress added the criterion of sustainability as an additional selection criterion in its investment strategy. In 2007 sustainable investment once again became a key priority for the Board of Directors. The Board assessed whether it was possible to increase the number of portfolios for which 'sustainability' could be used as a criterion. A key component of their strategy was that sustainable investment should not come at the expense of returns. Progress uses the following criteria with respect to sustainability: discrimination, fraud and corruption, child labour, human rights violations, environmental crime and violations of laws and codes. Information on these criteria is embedded in the decision-making structure based on which the portfolio manager selects equities. Each quarter, an external party conducts a sustainability analysis of the continental European investment portfolio managed by the fund itself.
