Basis of Presentation and Use of Estimates The accompanying unaudited consolidated financial statements have been prepared pursuant to the rules of the Securities and Exchange Commission (the “SEC”).

The impact of the reclassification is a reduction in “Billboard” revenues of $2.6 million and a corresponding increase in “Transit and other” revenues of $2.6 million for the three months ended March 31, 2014. These financial statements should be read in conjunction with the more detailed financial statements and notes thereto, included in our Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on March 6, 2015. We have revised the previously reported Condensed Consolidated Statement of Cash Flows for three months ended March 31, 2014. Historically, non-cash purchases of property and equipment were previously included within capital expenditures. The revision increased Net cash used in investing activities and increased Net cash provided by operating activities by $7.5 million for the three months ended March 31, 2014. We do not believe that these misclassifications were material to the previously reported interim financial statements. The above adjustments had no effect on previously reported Statements of Operations, Statements of Financial Position or Statements of Invested Equity/Stockholders' Equity. The preparation of our financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amount of revenues and expenses during the reporting period. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Basis of Presentation and Use of Estimates

The accompanying unaudited consolidated financial statements have been prepared pursuant to the rules of the Securities and Exchange Commission (the “SEC”). In the opinion of our management, the accompanying unaudited financial statements reflect all adjustments, consisting of normal and recurring adjustments, necessary for a fair presentation of our financial position, results of operations and cash flows for the periods presented. Certain previously reported amounts within Revenues have been reclassified to conform with the current presentation. The impact of the reclassification is a reduction in “Billboard” revenues of $2.6 million and a corresponding increase in “Transit and other” revenues of $2.6 million for the three months ended March 31, 2014. These financial statements should be read in conjunction with the more detailed financial statements and notes thereto, included in our Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on March 6, 2015.

We have revised the previously reported Condensed Consolidated Statement of Cash Flows for three months ended March 31, 2014. Historically, non-cash purchases of property and equipment were previously included within capital expenditures. The revision increased Net cash used in investing activities and increased Net cash provided by operating activities by $7.5 million for the three months ended March 31, 2014. We do not believe that these misclassifications were material to the previously reported interim financial statements. The above adjustments had no effect on previously reported Statements of Operations, Statements of Financial Position or Statements of Invested Equity/Stockholders' Equity.

The preparation of our financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amount of revenues and expenses during the reporting period. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
