General	General The information contained in the following notes to the consolidated financial statements is condensed from that which would appear in the annual consolidated financial statements; accordingly, the consolidated financial statements included herein should be reviewed in conjunction with the consolidated financial statements for the fiscal year ended December 31, 2011, and related notes thereto, included in the 2011 Form 10-K filed by Crown Castle International Corp. ("CCIC") with the SEC. All references to the "Company" include CCIC and its subsidiary companies unless otherwise indicated or the context indicates otherwise. The Company owns, operates and leases shared wireless infrastructure, including: (1) towers, (2) distributed antenna systems ("DAS"), a type of small cell ("small cells"), and (3) third party land interests, including ground lease related assets (unless the context otherwise suggests or requires, references herein to "wireless infrastructure" include towers, small cells and third party land interests). The Company's core business is renting space on its towers, small cells and, to a lesser extent, third party land interests (collectively, "site rental business") via long-term contracts in various forms. The Company also provides certain network services relating to its wireless infrastructure, consisting of installation services, and site development services relating to existing and new antenna installations on its wireless infrastructure. The Company conducts its operations through wireless infrastructure portfolios in the United States (including Puerto Rico) and Australia.

The year end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. Accounting measurements at interim dates inherently involve greater reliance on estimates than at year end. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the entire year. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
