Deal and ratings review, week ending May 26 2016

A highlight of the week was Westpac Banking Corporation (Westpac)'s debut in the green-bond market. Westpac added a A$500 million (US$361.2 million) green-bond tranche to its latest five-year benchmark becoming the first issuer in Australia to include a green tranche alongside non-green notes. Meanwhile, Port of Brisbane became the first triple-B corporate issuer of the year.
