Note 1: BASIS OF PRESENTATION AND NEW ACCOUNTING STANDARDS

Preparation of Interim Financial Statements

The accompanying consolidated financial statements were prepared by Clear Channel Outdoor Holdings, Inc. (the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, in the opinion of management, include all normal and recurring adjustments necessary to present fairly the results of the interim periods shown. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such SEC rules and regulations. Management believes that the disclosures made are adequate to make the information presented not misleading. Due to seasonality and other factors, the results for the interim periods are not necessarily indicative of results for the full year. The financial statements contained herein should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2010 Annual Report on Form 10-K.

The consolidated financial statements include the accounts of the Company and its subsidiaries and give effect to allocations of expenses from the Company’s indirect parent entity, Clear Channel Communications, Inc. (“Clear Channel Communications”). These allocations were made on a specifically identifiable basis or using relative percentages of headcount or other methods management considered to be a reasonable reflection of the utilization of services provided. Investments in companies in which the Company owns 20 percent to 50 percent of the voting common stock or otherwise exercises significant influence over operating and financial policies of the company are accounted for under the equity method. All significant intercompany transactions are eliminated in the consolidation process.

Certain prior-period amounts have been reclassified to conform to the 2011 presentation.

New Accounting Pronouncements

In December 2010, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2010-29, Disclosure of Supplementary Pro Forma Information for Business Combinations. This ASU updates Topic 805, Business Combinations, to specify that if a public entity presents comparative financial statements, the entity should disclose revenue and earnings of the combined entity as though the business combination that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period only. The amendments of this ASU are effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. The Company adopted the provisions of ASU 2010-29 on January 1, 2011 without material impact to the Company’s disclosures.

Note 2: PROPERTY, PLANT AND EQUIPMENT, INTANGIBLE ASSETS AND GOODWILL

Property, Plant and Equipment

The Company’s property, plant and equipment consisted of the following classes of assets at March 31, 2011 and December 31, 2010, respectively:

Definite-lived Intangible Assets

The Company has definite-lived intangible assets which consist primarily of transit and street furniture contracts, site leases and other contractual rights, all of which are amortized over the shorter of either the respective lives of the agreements or over the period of time the assets are expected to contribute directly or indirectly to the Company’s future cash flows. The Company periodically reviews the appropriateness of the amortization periods related to its definite-lived assets. These assets are recorded at cost.

The following table presents the gross carrying amount and accumulated amortization for each major class of definite-lived intangible assets at March 31, 2011 and December 31, 2010, respectively:

Total amortization expense related to definite-lived intangible assets for the three months ended March 31, 2011 and 2010 was $23.0 million and $23.6 million, respectively.

As acquisitions and dispositions occur in the future, amortization expense may vary. The following table presents the Company’s estimate of amortization expense for each of the five succeeding fiscal years for definite-lived intangible assets.

(In thousands)

Indefinite-lived Intangible Assets

The Company’s indefinite-lived intangibles consist primarily of billboard permits in its Americas segment. Due to significant differences in both business practices and regulations, billboards in the International segment are subject to long-term, finite contracts unlike the Company’s permits in the United States and Canada. Accordingly, there are no indefinite-lived assets in the International segment.

Goodwill

The following table presents the changes in the carrying amount of goodwill in each of the Company’s reportable segments.

Note 3: LONG-TERM DEBT

Long-term debt at March 31, 2011 and December 31, 2010 consisted of the following:

The aggregate market value of the Company’s debt based on market prices for which quotes were available was approximately $2.8 billion at March 31, 2011 and December 31, 2010.

Clear Channel Communications’ Refinancing Transactions

During the first quarter of 2011 Clear Channel Communications amended its senior secured credit facilities and its receivables based credit facility (the “Amendments”) and issued $1.0 billion aggregate principal amount of 9.0% Priority Guarantee Notes due 2021. Clear Channel Communications used a portion of the proceeds from the Priority Guarantee Notes offering to prepay $500.0 million of the indebtedness outstanding under its senior secured credit facilities. As a result of the prepayment, the revolving credit commitments under Clear Channel Communications’ revolving credit facility were permanently reduced from $2.0 billion to $1.9 billion and the sub-limit under which certain of the Company’s international subsidiaries may borrow (to the extent that Clear Channel Communications’ has not already borrowed against this capacity) was reduced from $150.0 million to $145.0 million. The Amendments, among other things, provide greater flexibility for the Company and its subsidiaries to incur new debt, provided that the net proceeds distributed to Clear Channel Communications from the issuance of such new debt are used to pay down senior secured credit facility indebtedness.

Note 4: SUPPLEMENTAL DISCLOSURES

Income tax benefit

The Company’s income tax benefit for the three months ended March 31, 2011 and 2010, respectively, consisted of the following components:

The effective tax rate is the provision for income taxes as a percent of income before income taxes. The effective tax rate for the three months ended March 31, 2011 was 68.3%. The 2011 effective tax rate was primarily impacted by the Company’s settlement of U.S. federal and state tax examinations during the quarter. Pursuant to the settlements, the Company recorded a reduction to income tax expense of approximately $3.3 million to reflect the net tax benefits of the settlements. In addition, the effective rate was impacted by the Company’s ability to benefit from certain tax loss carryforwards in foreign jurisdictions due to taxable income where the losses previously did not provide a benefit.

The Company’s effective tax rate for the three months ended March 31, 2010 was 18.0%. The 2010 effective rate was impacted primarily as a result of the Company’s inability to benefit from tax losses in certain foreign jurisdictions due to the uncertainty of the ability to utilize those losses in future years.

During the quarters ended March 31, 2011 and 2010, cash paid for interest and income taxes, net of income tax refunds of $0.2 million and $1.2 million, respectively, was as follows:

Note 5: FAIR VALUE MEASUREMENTS

The Company holds marketable equity securities classified in accordance with the provisions of ASC 320-10. These marketable equity securities are measured at fair value on each reporting date using quoted prices in active markets. Due to the fact that the inputs used to measure the marketable equity securities at fair value are observable, the Company has categorized the fair value measurements of the securities as Level 1. The Company records its investments in these marketable equity securities on the balance sheet as “Other Assets.”

The cost, unrealized holding gains or losses, and fair value of the Company’s investments at March 31, 2011 and December 31, 2010 are as follows:

Note 6: COMMITMENTS AND CONTINGENCIES

The Company and its subsidiaries are currently involved in certain legal proceedings arising in the ordinary course of business and, as required, the Company has accrued its estimate of the probable costs for resolution of those claims for which the occurrence of loss is probable and the amount can be reasonably estimated. These estimates have been developed in consultation with counsel and are based upon an analysis of potential results, assuming a combination of litigation and settlement strategies. It is possible, however, that future results of operations for any particular period could be materially affected by changes in the Company’s assumptions or the effectiveness of its strategies related to these proceedings.

In 2006, two of the Company’s operating businesses (L&C Outdoor Ltda. (“L&C”) and Publicidad Klimes Sao Paulo Ltda. (“Klimes”), respectively) in the Sao Paulo, Brazil market received notices of infraction from the state taxing authority, seeking to impose a value added tax (“VAT”) on such businesses, retroactively for the period from December 31, 2001 through January 31, 2006. The taxing authority contends that the Company’s businesses fall within the definition of “communication services” and as such are subject to the VAT.

The Company has filed separate petitions to challenge the imposition of this tax against each of its businesses. The Company’s challenge for L&C was unsuccessful at the first administrative level, but successful at the second administrative level. The state taxing authority filed an appeal to the third and final administrative level, which required consideration by a full panel of 16 administrative law judges. On September 27, 2010, the Company received an unfavorable ruling at this final administrative level concluding that the VAT applied to L&C and intends to appeal this ruling to the judicial level. The Company has filed a petition to have the case remanded to the second administrative level for consideration of the reasonableness of the amount of the penalty assessed against it. The amounts allegedly owed by L&C are approximately $9.6 million in taxes, approximately $19.2 million in penalties and approximately $29.4 million in interest (as of March 31, 2011 at an exchange rate of 0.60). Based on management’s review of the law in and the outcome of similar cases in other Brazilian states, the Company has not accrued any costs related to these claims and believes the occurrence of loss is not probable.

The Company’s challenge for Klimes was unsuccessful at the first administrative level, and denied at the second administrative level on or about September 24, 2009. On January 5, 2011, the administrative law judges at the third administrative level published a ruling that the VAT applies to Klimes but reduced the penalty assessed by the taxing authority. With the penalty reduction, the amounts allegedly owed by Klimes are approximately $10.9 million in taxes, approximately $5.4 million in penalties and approximately $18.2

million in interest (as of March 31, 2011 at an exchange rate of 0.60). In mid-January 2011, the taxing authority filed an extraordinary appeal to the third administrative level, asking that it reconsider the decision to reduce the penalty assessed against Klimes. The president of the third administrative level rejected that appeal. In late February 2011, the Company filed a writ of mandamus in the 13a lower public treasury court in São Paulo, State of São Paulo, appealing the administrative court’s decision that the VAT applies to Klimes. On that same day, Klimes filed a motion for an injunction barring the taxing authority from collecting the tax, penalty and interest while the appeal is pending. The court denied the motion in early April 2011. The Company appealed the decision to the São Paulo State Higher Court, which affirmed in late April 2011. Based on management’s review of the law in and the outcome of similar cases in other Brazilian states, the Company has not accrued any costs related to these claims and believes the occurrence of loss is not probable.

As of March 31, 2011, Clear Channel Communications had outstanding commercial standby letters of credit and surety bonds of $42.1 million and $43.7 million, respectively, held on behalf of the Company. These letters of credit and surety bonds relate to various operational matters, including insurance, bid and performance bonds, as well as other items. As of March 31, 2011, the Company had $59.1 million in letters of credit outstanding, of which $56.6 million of letters of credit were cash secured.

Note 7: RELATED PARTY TRANSACTIONS

The Company records net amounts due to or from Clear Channel Communications as “Due from/to Clear Channel Communications” on the condensed consolidated balance sheets. The accounts represent the revolving promissory note issued by the Company to Clear Channel Communications and the revolving promissory note issued by Clear Channel Communications to the Company, in the face amount of $1.0 billion, or if more or less than such amount, the aggregate unpaid principal amount of all advances. The accounts accrue interest pursuant to the terms of the promissory notes and are generally payable on demand.

Included in the accounts are the net activities resulting from day-to-day cash management services provided by Clear Channel Communications. As a part of these services, the Company maintains collection bank accounts swept daily into accounts of Clear Channel Communications (after satisfying the funding requirements of the Trustee Account). In return, Clear Channel Communications funds the Company’s controlled disbursement accounts as checks or electronic payments are presented for payment. The Company’s claim in relation to cash transferred from its concentration account is on an unsecured basis and is limited to the balance of the “Due from Clear Channel Communications” account. At March 31, 2011 and December 31, 2010, the asset recorded in “Due from Clear Channel Communications” on the condensed consolidated balance sheets was $408.9 million and $383.8 million, respectively. The net interest income for the three months ended March 31, 2011 and 2010 was $9.1 million and $3.4 million, respectively. At March 31, 2011 and December 31, 2010, the interest rate on the “Due from Clear Channel Communications” account was 9.25%, which represents the fixed interest rate on the Clear Channel Worldwide Holdings senior notes.

Clear Channel Communications has a $1.9 billion multi-currency revolving credit facility with a maturity in July 2014 which includes a $145.0 million sub-limit that certain of the Company’s International subsidiaries may borrow against to the extent Clear Channel Communications has not already borrowed against this capacity and is compliant with its covenants under the revolving credit facility. As of March 31, 2011, the Company had no outstanding borrowings under the $145.0 million sub-limit facility. Clear Channel Communications has borrowed the entire capacity.

The Company provides advertising space on its billboards for radio stations owned by Clear Channel Communications. For the three months ended March 31, 2011 and 2010, the Company recorded $0.9 million and $1.1 million, respectively, in revenue for these advertisements.

Under the Corporate Services Agreement between Clear Channel Communications and the Company, Clear Channel Communications provides management services to the Company, which include, among other things: (i) treasury, payroll and other financial related services; (ii) executive officer services; (iii) human resources and employee benefits services; (iv) legal and related services; (v) information systems, network and related services; (vi) investment services; (vii) procurement and sourcing support services; and (viii) other general corporate services. These services are charged to the Company based on actual direct costs incurred or allocated by Clear Channel Communications based on headcount, revenue or other factors on a pro rata basis. For the three months ended March 31, 2011 and 2010, the Company recorded $5.7 million and $8.9 million, respectively, as a component of corporate expenses for these services.

Pursuant to the Tax Matters Agreement between Clear Channel Communications and the Company, the operations of the Company are included in a consolidated federal income tax return filed by Clear Channel Communications. The Company’s provision for income taxes has been computed on the basis that the Company files separate consolidated federal income tax returns with its

subsidiaries. Tax payments are made to Clear Channel Communications on the basis of the Company’s separate taxable income. Tax benefits recognized on the Company’s employee stock option exercises are retained by the Company.

The Company computes its deferred income tax provision using the liability method in accordance with the provisions of ASC 740-10, as if the Company was a separate taxpayer. Deferred tax assets and liabilities are determined based on differences between financial reporting bases and tax bases of assets and liabilities and are measured using the enacted tax rates expected to apply to taxable income in the periods in which the deferred tax asset or liability is expected to be realized or settled. Deferred tax assets are reduced by valuation allowances if the Company believes it is more likely than not some portion or all of the asset will not be realized.

Pursuant to the Employee Matters Agreement, the Company’s employees participate in Clear Channel Communications’ employee benefit plans, including employee medical insurance and a 401(k) retirement benefit plan. These costs are recorded as a component of selling, general and administrative expenses and were approximately $3.0 million and $2.6 million for the three months ended March 31, 2011 and 2010, respectively.

Note 8: EQUITY AND COMPREHENSIVE INCOME (LOSS)
