U.S.-based offshore vessel provider Hornbeck Offshore Services Inc. continues to face weak market conditions and upcoming debt maturities, and we continue to expect the company will restructure its debt within the next six months. We are affirming our 'CCC-' issuer credit rating on Hornbeck Offshore. We are also affirming our 'D' issue-level rating on the company's convertible notes due 2019 and our 'CCC' issue-level and '2' recovery rating on its senior notes due 2020 and 2021. The negative rating outlook reflects our view that Hornbeck will likely enter into a distressed exchange or debt restructuring for its 2020 or 2021 debt maturities over the next six months.
