Adjusted EBITDA achievement is a primary metric used in the EnLink Midstream Partners, LP (“ENLK” or “the Partnership”) credit facility and short-term incentive program for compensating its employees. Adjusted EBITDA and distributable cash flow, as defined below, are not measures of financial performance or liquidity under GAAP. They should not be considered in isolation or as an indicator of EnLink Midstream’s performance. Furthermore, they should not be seen as a substitute for metrics prepared in accordance with GAAP. See ENLK’s and ENLC’s filings with the Securities and Exchange Commission for more information.
