Part of series developed by UN Women and the Luxembourg Stock Exchange with the support of Luxembourg Aid & Devlopment, this case study examines the National Australia Bank’s (NAB) 500 M AUD Social Bond issued in 2017, which was Australia's first Social Bond and the world's first social bond promoting workplace gender equality. A social bond is a type of use of proceeds (UoP) gender bond, which directs the bond proceeds toward the economic activities of identified investees. The net proceeds were earmarked for refinancing a portfolio of existing loans and assets for organizations that had been awarded the Employer of Choice for Gender Equality citation (EOCGE) by the Workplace Gender Equality Agency (WGEA). To receive an EOCGE citation, organizations must meet requirements under seven focus areas intended to improve gender equality in workplaces.
