For 2015, represents a non-cash impairment charge related to our pressure pumping services segment. For 2016, represents a non-cash impairment charge related to our directional drilling services segment. See Note 4 to the Quintana Energy Services LP financial statements included in this prospectus for additional detail. For 2016, represents professional fees related to investment banking, accounting and legal services associated with entering into the Term Loan that were recorded in general and administrative expenses.
