SAO PAULO (Standard&Poor's) Aug. 13, 2014--Standard&Poor's Ratings Services said today that its 'BB-' global scale and 'brA' national scale corporate credit ratings and 'BB-' issue-level ratings on Minerva S.A. remain unchanged following the proposed add-on to the company's 2023 notes. We expect Minerva to use the proceeds from the issuance to pay down interest and short-term debt, maintaining its current gross and net credit metrics and improving its capital structure somewhat.
