Non-GAAP Financial Measures
(Crown Castle)
Crown Castle defines Adjusted EBITDA as net income (loss) plus cumulative effect of change in accounting principle, income (loss) from discontinued operations,
minority interests, credit (provision) for income taxes, interest expense, amortization of deferred financing costs, interest and other income (expense),
depreciation, amortization and accretion, operating stock-based compensation charges, asset write-down charges and restructuring charges (credits).
Adjusted EBITDA is not intended as an alternative measure of cash flow from operations or operating results (as determined in accordance with Generally Accepted Accounting Principles (GAAP)). 
($ in thousands, except per share and per tower amounts)
Adjusted EBITDA for the quarter ended June 30, 2006 is computed as follows:

loss on early extinguishment of debt, non-cash stock-based compensation expense, Sprint integration costs, straight-line portion of revenues
and expense, gain or loss on sale of properties, gain or loss on
derivative instruments and impairment loss on assets held for sale. Adjusted EBITDA
