This is an open-label, single-dose study designed to assess the pharmacokinetics and safety of ABT-493 and/or ABT-530 in subjects with impaired hepatic function and compare them to those in subjects with normal hepatic function. Twenty-four subjects will be selected and enrolled according to the subject selection criteria: 6 subjects with mild stable chronic hepatic impairment (Group I), 6 subjects with moderate stable chronic hepatic impairment (Group II), 6 subjects with severe stable chronic hepatic impairment (Group III) and 6 subjects with normal hepatic function (Group IV).
