We are raising our corporate credit rating on Avis Budget to 'BB-' from 'B+' and removing the rating from CreditWatch positive. We are also raising our issue-level ratings on Avis Budget's senior secured debt and unsecured debt by one notch and removing them from CreditWatch positive. The recovery ratings remain unchanged.
