2013 Guidance Remains UnchangedFor the full year of 2013, the Company’s expectations for capital expenditures and free cash flow remain unchanged and are within a range of $625 million to $675 million and $825 million to $925 million, respectively. The Company expects that in 2013, absent any further legislative changes in 2013, its cash taxes guidance remains unchanged and will be in the range of $125 million to $150 million. Non-GAAP Measures The Company uses certain non-GAAP financial measures in evaluating its performance. These include non-GAAP adjusted net income attributable to common shareholders of Frontier, free cash flow and operating cash flow. A reconciliation of the differences between non-GAAP adjusted net income attributable to common shareholders of Frontier, free cash flow and operating cash flow and the most comparable financial measures calculated and presented in accordance with GAAP is included in the tables that follow. The non-GAAP financial measures are by definition not measures of financial performance under GAAP, and are not alternatives to operating income or net income attributable to common shareholders of Frontier as reflected in the statement of operations or to cash flow as reflected in the statement of cash flows, and are not necessarily indicative of cash available to fund all cash flow needs. The non-GAAP financial measures used by the Company may not be comparable to similarly titled measures of other companies. 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 and 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 the early extinguishment of debt, gain on sale of Mohave partnership interest, investment gains, discrete tax items, integration costs, severance 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.
