Management presents these non-GAAP financial measures because it considers them to be important supplemental measures of performance. Management uses the non-GAAP financial measures for planning purposes, including analysis of the Company’s performance against prior periods, the preparation of operating budgets and to determine appropriate levels of operating and capital investments. Management also believes that the non-GAAP financial measures provide additional insight for analysts and investors in evaluating the Company’s financial and operational performance.
