Nature of Operations and Basis of Presentation [Abstract]

Basis of Presentation

2. Basis of Presentation

Our accompanying unaudited, condensed, consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information and in accordance with the rules and regulations of the United States Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements as permitted under applicable rules and regulations. In the opinion of management, all normal recurring adjustments considered necessary for a fair presentation have been included. The results of operations for the three and nine months ended September 30, 2011 are not necessarily indicative of the results to be expected for the full year ending December 31, 2011. For further information, refer to our consolidated financial statements and notes thereto included in our 2010 Annual Report on Form 10-K.

Certain reclassifications have been made herein to 2010 amounts to conform to the current year presentation. In our condensed, consolidated balance sheet as of December 31, 2010, we corrected certain errors in presentation by reclassifying $5.8 million to temporary equity (mezzanine) from noncontrolling interests included in permanent equity related to partnership agreements that contain certain terms which may require us to purchase the partners’ equity based upon certain contingencies. As these agreements do not contain a mandatory redemption clause, the balances are now correctly classified in temporary equity (mezzanine). Additionally, we reclassified $506,000 from noncontrolling interests in permanent equity to other liabilities related to our mandatorily redeemable partnership interests. The change in classification of our redeemable noncontrolling interests also impacts our condensed, consolidated statement of equity for the nine months ended September 30, 2010, accordingly, certain amounts related to redeemable noncontrolling interests were reclassified from the noncontrolling interests column in the statement, see Note 13, Noncontrolling Interests, which presents a summary of the amounts reclassified.

During the quarter ended March 31, 2011, we corrected an error related to our deferred revenue and related deferred cost for certain equipment sales governed by recently revised accounting guidance related to multiple element arrangements. The correction resulted in the recognition of $4.0 million of previously deferred revenue and $3.8 million of previously deferred costs.

The preparation of our condensed, consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in our condensed, consolidated financial statements and notes thereto. Actual results could differ from those estimates.
