The Company believes that the presentation of non-GAAP financial measures provides useful information to investors regarding the Company’s financial condition and results of operations because these measures, when used in conjunction with related GAAP financial measures, (i) together provide a more comprehensive view of the Company’s core operations and ability to generate cash flow, (ii) provide investors with the financial analytical framework upon which management bases financial, operational, compensation and planning decisions and (iii) presents measurements that investors and rating agencies have indicated to management are useful to them in assessing the Company and its results of operations. In addition, the Company believes that non-GAAP adjusted net income attributable to common shareholders of Frontier, free cash flow, operating cash flow and adjusted operating cash flow, as the Company defines them, can assist in comparing performance from period to period, without taking into account factors affecting operating income or net income attributable to common shareholders of Frontier in the statement of operations, or cash flow reflected in the statement of cash flows, including changes in working capital and the timing of purchases and payments. The Company has shown adjustments to its financial presentations to exclude losses on early extinguishment of debt, gain on sale of Mohave partnership interest, investment gains, discrete tax items, acquisition and integration costs, acquisition related interest expense, severance costs, pension settlement costs and non-cash pension and other postretirement benefit costs, as disclosed in the attached Schedules A and B, because investors have indicated to management that such adjustments are useful to them in assessing the Company and its results of operations.
Management uses these non-GAAP financial measures to (i) assist in analyzing the Company’s underlying financial performance from period to period, (ii) evaluate the financial performance of its business units, (iii) analyze and evaluate strategic and operational decisions, (iv) establish criteria for compensation decisions, and (v) assist management in understanding the Company’s ability to generate cash flow and, as a result, to plan for future capital and operational decisions. Management uses these non-GAAP financial measures in conjunction with related GAAP financial measures.
