Brazil-based infrastructure operator Invepar has around R$1.1 billion in debentures maturing on Dec. 11, 2018, at the holding level. Given that we believe that the refinancing risk has increased now, we're placing our 'BB-' global and 'brAA+' national scale ratings on CreditWatch with negative implications. This indicates our concern about Invepar's ability to extend its maturities and a 50% probability of multiple-notch downgrade if the company is unable to refinance the debentures by early November. On Aug. 28, 2018, S&P Global Ratings placed its 'BB-' global scale and 'brAA+' national scale ratings on Investimentos e Participacoes em Infraestrutura S.A. – Invepar on CreditWatch negative. At the same time, we placed on CreditWatch negative our 'brAA+' issuer credit and issue-level ratings
