Adjusted EBITDA should not be considered in isolation of, or as a substitute for, net income, operating income, cash flows from operating activities or any other measure for determining our operating performance or liquidity that is calculated in accordance with GAAP.A quantitative reconciliation of Adjusted EBITDA to net (loss) income, the most directly comparable financial measure calculated and presented in accordance with GAAP, is provided under "Reconciliation of Non-GAAP Financial Measures to Most Directly Comparable GAAP Measures" below. Free Cash Flow Free cash flow is also utilized by management to analyze the cash generated by our business. Free cash flow measures the amount of cash generated during the applicable period that could be used to fund acquisitions or other growth opportunities or for reinvestment in our business, after funding station and corporate, general and administrative expenses (excluding transaction costs), debt service, income taxes, and capital expenditures. We define free cash flow as net income (loss) before any non-operating expenses, including net interest expense, stock-based compensation expense, depreciation and amortization, gain or loss on the exchange or sale of assets or stations (if any), and any realized gain or loss on derivative instruments, any impairment of intangible assets and goodwill, net of interest expense (excluding any non-cash charges or credits for changes in values of swaps and amortization of debt issuance costs), income taxes paid and capital expenditures. Management excludes depreciation and amortization, any gain or loss on the exchange or sale of assets or stations, any realized gain or loss on derivative instruments or impairment of intangible assets and goodwill and other non-cash expenses, including stock-based compensation, from net income (loss) as they do not represent cash transactions. Management deducts payments for debt service, income taxes and capital expenditures since these represent amounts that are consistently necessary for our continuing operations, in order to arrive at free cash flow available for growth opportunities or reinvestment in our business.
