NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Tabular dollars in millions, except per share amounts)

1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business—CBS Corporation (together with its consolidated subsidiaries unless the context otherwise requires, the "Company" or "CBS Corp.") is comprised of the following segments: Television (CBS Television, comprised of the CBS Television Network, television stations, and its television production and syndication operations; Showtime Networks; and CBS College Sports Network), Radio (CBS Radio), Outdoor (CBS Outdoor) and Publishing (Simon & Schuster).

Basis of Presentation—The accompanying unaudited consolidated financial statements of the Company have been prepared pursuant to the rules of the Securities and Exchange Commission ("SEC"). These financial statements should be read in conjunction with the more detailed financial statements and notes thereto, included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2007.

In the opinion of management, the accompanying unaudited financial statements reflect all adjustments, consisting of only normal and recurring adjustments, necessary for a fair statement of the financial position, results of operations and cash flows of the Company for the periods presented. Certain previously reported amounts have been reclassified to conform to the current presentation.

Use of Estimates—The preparation of the Company's financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of expenses during the reporting period. The Company bases its 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.

Net Earnings per Common Share—Basic earnings per share ("EPS") is based upon net earnings divided by the weighted average number of common shares outstanding during the period. Diluted EPS reflects the effect of the assumed exercise of stock options and vesting of restricted stock units ("RSUs"), market-based performance share units ("PSUs") and restricted shares only in the periods in which such effect would have been dilutive. For the three months ended March 31, 2008 and 2007, respectively, stock options to purchase 37.1 million and 20.1 million shares of CBS Corp. Class B Common Stock were outstanding but excluded from the calculation of diluted EPS because their inclusion would have been anti-dilutive.

The table below presents a reconciliation of weighted average shares used in the calculation of basic and diluted EPS.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
(Tabular dollars in millions, except per share amounts)

Comprehensive Income (Loss)—Total comprehensive income for the Company includes net earnings and other comprehensive income (loss) items listed in the table below.

Other Liabilities—Other liabilities consist primarily of the noncurrent portion of residual liabilities of previously disposed businesses, participants' share and royalties payable, program rights, deferred compensation and other employee benefit accruals.

Additional Paid-In Capital—For the three months ended March 31, 2008 and 2007, the Company recorded dividends of $171.2 million and $162.6 million, respectively, as a reduction to additional paid-in capital as the Company had an accumulated deficit balance.

Adoption of New Accounting Standards—Effective January 1, 2008, the Company adopted Financial Accounting Standards Board ("FASB") Statement of Financial Accounting Standards ("SFAS") No. 157, "Fair Value Measurements" ("SFAS 157") for its financial assets and liabilities. In February 2008, the FASB issued FASB Staff Position ("FSP") No. FAS 157-2, "Effective Date of FASB Statement No. 157", which delays the effective date of SFAS 157 for nonfinancial assets and liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually), to fiscal years beginning after November 15, 2008 and interim periods within those fiscal years. SFAS 157 establishes a framework for measuring fair value under generally accepted accounting principles and expands disclosures about fair value measurement. The adoption of SFAS 157 on January 1, 2008 did not have a material effect on the Company's consolidated financial statements. See Note 13 for additional information.

In February 2007, the FASB issued SFAS No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities – Including an amendment of FASB Statement No. 115" ("SFAS 159") effective as of the beginning of the first fiscal year that begins after November 15, 2007. SFAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value with changes in fair value recognized in earnings for each reporting period. The adoption of SFAS 159 on January 1, 2008 did not have any effect on the Company's consolidated financial statements as the Company did not elect any eligible items for fair value measurement.

Recent Pronouncements—In March 2008, the FASB issued SFAS No. 161, "Disclosures about Derivative Instruments and Hedging Activities – an amendment of FASB Statement No. 133" ("SFAS 161") effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. SFAS 161 requires an entity to provide enhanced disclosures about derivative instruments and hedging activities.

(Tabular dollars in millions, except per share amounts)

In December 2007, the FASB issued SFAS No. 141 (revised 2007), "Business Combinations" ("SFAS 141R"), effective 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, 2008. SFAS 141R establishes principles and requirements for how an acquirer recognizes and measures identifiable assets acquired, liabilities assumed, any noncontrolling interest in the acquiree and goodwill. SFAS 141R also expands disclosure requirements for business combinations.

In December 2007, the FASB issued SFAS No. 160, "Noncontrolling Interests in Consolidated Financial Statements – an amendment of ARB No. 51" ("SFAS 160") effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. SFAS 160 establishes accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. The adoption of SFAS 160 is not expected to have a material effect on the Company's consolidated financial statements.

2) STOCK-BASED COMPENSATION

The following table summarizes the Company's stock-based compensation expense for the three months ended March 31, 2008 and 2007.

During the first quarter of 2008, the Company granted 3.7 million RSUs with a weighted-average per unit grant date fair value of $23.97. RSU grants during the first quarter of 2008 generally vest over a three- to four-year service period. Certain RSU awards are also subject to satisfying performance conditions. During the first quarter of 2008, the Company also granted ..2 million PSUs with an aggregate grant date fair value of $7.3 million. The number of shares that will be issued upon vesting of PSUs can range from 0% to 300% of the target award, based on the ranking of the total shareholder return for CBS Corp. Class B Common Stock within the S&P 500 Index over a designated three-year measurement period, or in certain circumstances, based on a one-year measurement period or the achievement of established operating performance goals. During the first quarter of 2008, the Company also granted 2.3 million stock options with a weighted-average exercise price of $23.99. Stock option grants during 2008 generally vest over a three-to four-year service period.

Total unrecognized compensation cost related to non-vested RSUs, PSUs and restricted shares at March 31, 2008 was $237.0 million, which is expected to be expensed over a weighted-average period of 2.7 years. Total unrecognized compensation cost related to unvested stock option awards and stock option equivalents at March 31, 2008 was $48.6 million, which is expected to be expensed over a weighted-average period of 3.2 years.

7) BANK FINANCING AND DEBT

The following table sets forth the Company's long-term debt.

(a)  As of March 31, 2008 and December 31, 2007, the senior debt balances included (i) a net unamortized premium of $25.5 million and $26.2 million, respectively, and (ii) a change in the carrying value of the debt relating to fair value hedges of $43.4 million and $(5.0) million, respectively.

(b)  Included in "Liabilities of discontinued operations" on the Consolidated Balance Sheets.

The senior debt of CBS Corp. is fully and unconditionally guaranteed by its wholly owned subsidiary, CBS Operations Inc. Senior debt in the amount of $52.2 million of the Company's wholly owned subsidiary, CBS Broadcasting Inc., is not guaranteed.

Credit Facility

As of March 31, 2008, the Company had a $3.0 billion revolving credit facility due December 2010 (the "Credit Facility"), primarily to support commercial paper borrowings. At March 31, 2008, the Company had no commercial paper borrowings and was in compliance with all covenants under the Credit Facility, including the requirement that the Company maintain a minimum coverage ratio. As of March 31, 2008, the remaining availability under this Credit Facility, net of outstanding letters of credit, was $2.81 billion.

Accounts Receivable Securitization Program

As of March 31, 2008, the Company had $550.0 million outstanding under its revolving accounts receivable securitization program. The program results in the sale of receivables on a non-recourse basis to unrelated third parties on a one-year renewable basis, thereby reducing accounts receivable on the Company's Consolidated Balance Sheet. The Company entered into this arrangement because it provides an additional source of liquidity. Proceeds from this program were used to reduce outstanding borrowings. The terms of the revolving securitization arrangement require that the receivable pools subject to the program meet certain performance ratios. As of March 31, 2008, the Company was in compliance with the required ratios under the receivable securitization program.

On February 21, 2008, the Company announced a quarterly cash dividend of $.25 per share on its Class A and Class B Common Stock payable on April 1, 2008. The total dividend was $171.2 million of which $167.0 million was paid on April 1, 2008 and $4.2 million was accrued to be paid upon vesting of RSUs and restricted shares. During the first quarter of 2008, the Company paid $168.8 million for the dividend declared on November 1, 2007 and for dividend payments on RSUs that vested during the first quarter of 2008. Dividend declarations during 2008 and 2007 were recorded as a reduction to additional paid-in capital as the Company had an accumulated deficit balance.

In January 2008, the Company received 6.0 million shares of CBS Corp. Class B Common Stock upon settlement of a 2007 accelerated share repurchase transaction.

10) PROVISION FOR INCOME TAXES

The provision for income taxes represents federal, state and local, and foreign income taxes on earnings before income taxes, equity in loss of investee companies and minority interest. The provision for income taxes was $151.3 million and $204.2 million for the three months ended March 31, 2008 and 2007, respectively. The Company's effective income tax rate was 37.6% for the first quarter of 2008 versus 48.7% for the same prior-year period. The provision for income taxes for the first quarter of 2007 included a tax provision of $43.5 million related to radio station divestitures.

The Company is currently under examination by the Internal Revenue Service ("IRS") for the years 2004 and 2005. The examination is anticipated to be completed in the next twelve months. The ultimate outcome of the IRS examination, as well as an estimate of any related change to the reserve for uncertain tax positions, can not be determined currently.

11) COMMITMENTS AND CONTINGENCIES

Off-Balance Sheet Arrangements

Prior to the Separation of Former Viacom into CBS Corp. and Viacom Inc., Former Viacom had entered into guarantees with respect to obligations related to Blockbuster Inc. ("Blockbuster"), including certain Blockbuster store leases; Famous Players theater leases; certain UCI theater leases; and certain theater leases related to W.F. Cinema Holdings L.P. and Grauman's Theatres LLC. In connection with the Separation, Viacom Inc. has agreed to indemnify the Company with respect to these guarantees. In addition, the Company and Viacom Inc. have agreed to indemnify each other with respect to certain other matters pursuant to the Separation Agreement between the parties.

The Company has indemnification obligations with respect to letters of credit and surety bonds primarily used as security against non-performance in the normal course of business. At March 31, 2008, the outstanding letters of credit and surety bonds approximated $406.1 million and are not recorded on the Consolidated Balance Sheet.

In the course of its business, the Company both provides and receives indemnities which are intended to allocate certain risks associated with business transactions. Similarly, the Company may remain contingently liable for various obligations of a business that has been divested in the event that a third party does not live up to its obligations under an indemnification obligation. The Company records a liability for its indemnification obligations and other contingent liabilities when probable under generally accepted accounting principles.

Legal Matters

Indecency Regulation.    In March 2006, the FCC released certain decisions relating to indecency complaints against certain of the Company's owned television stations and affiliated stations. The FCC ordered the Company to pay a forfeiture of $550,000 in the proceeding relating to the broadcast of a Super Bowl half-time show by the Company's television stations. In May 2006, the FCC denied the Company's petition for reconsideration. In July 2006, the Company filed a Petition for Review of the forfeiture with the U.S. Court of Appeals for the Third Circuit and paid the $550,000 forfeiture in order to facilitate the Company's ability to bring the appeal. Oral argument was heard in September 2007. The Company is awaiting the court's decision.

In March 2006, the FCC also notified the Company and certain affiliates of the CBS Television Network of apparent liability for forfeitures relating to a broadcast of the program Without a Trace. The FCC proposed to assess a forfeiture of $32,500 against each of these stations, totaling $260,000 for the Company's owned stations. The Company is contesting the FCC decision and the proposed forfeitures.

In June 2007, the U.S. Court of Appeals for the Second Circuit vacated the FCC's November 2006 finding that the broadcast of fleeting and isolated expletives on another broadcast network was indecent and remanded the case to the FCC. On March 17, 2008, the U.S. Supreme Court granted the FCC's petition to review the U.S. Court of Appeals for the Second Circuit's decision.

Additionally, the Company, from time to time, has received and may receive in the future letters of inquiry from the FCC prompted by complaints alleging that certain programming on the Company's broadcasting stations included indecent material.

Claims Related to Former Businesses: Asbestos, Environmental and Other.    The Company is a defendant in lawsuits claiming various personal injuries related to asbestos and other materials, which allegedly occurred principally as a result of exposure caused by various products manufactured by Westinghouse, a predecessor, generally prior to the early 1970s. Westinghouse was neither a producer nor a manufacturer of asbestos. The Company is typically named as one of a large number of defendants in both state and federal cases. In the majority of asbestos lawsuits, the plaintiffs have not identified which of the Company's products is the basis of a claim. Claims against the Company in which a product has been identified principally relate to exposures allegedly caused by asbestos-containing insulating material in turbines sold for power-generation, industrial and marine use, or by asbestos containing grades of decorative micarta, a laminate used in commercial ships.

Claims are frequently filed and/or settled in large groups, which may make the amount and timing of settlements, and the number of pending claims, subject to significant fluctuation from period to period. The Company does not report as pending those claims on inactive, stayed, deferred or similar dockets which some jurisdictions have established for claimants who allege minimal or no impairment. As of March 31, 2008, the Company had pending approximately 72,870 asbestos claims, as compared with approximately 72,120 as of December 31, 2007 and approximately 72,510 as of March 31, 2007. Of the claims pending as of March 31, 2008, approximately 40,950 were pending in state courts, 28,310 in federal courts and, additionally, approximately 3,610 were third party claims pending in state courts. During the first quarter of 2008, the Company received approximately 1,600 new claims and closed or moved to an inactive docket approximately 850 claims. The Company reports claims as closed when it becomes aware that a dismissal order has been entered by a court or when the Company has reached agreement with the claimants on the material terms of a settlement. Settlement costs depend on the seriousness of the injuries that form the basis of the claim, the quality of evidence supporting the claims and other factors. The Company's total costs for the years 2007 and 2006 for settlement and defense of asbestos claims after insurance recoveries and net of tax benefits were approximately $17.5 million and $5.7 million, respectively. The Company's costs for settlement and defense of asbestos claims may vary year to year as insurance proceeds are not always recovered in the same period as the insured portion of the expenses. The Company believes that its reserves and insurance are adequate to cover its asbestos liabilities.

The Company from time to time receives claims from federal and state environmental regulatory agencies and other entities asserting that it is or may be liable for environmental cleanup costs and related damages principally relating to historical and predecessor operations of the Company. In addition, the Company from time to time receives personal injury claims including toxic tort and product liability claims (other than asbestos) arising from historical operations of the Company and its predecessors.

General.    On an ongoing basis, the Company defends itself in numerous lawsuits and proceedings and responds to various investigations and inquiries from federal, state and local authorities (collectively, "litigation"). Litigation is inherently uncertain and always difficult to predict. However, based on its understanding and evaluation of the relevant facts and circumstances, the Company believes that the above-described legal matters and other litigation to which it is a party are not likely, in the aggregate, to have a material adverse effect on its results of operations, financial position or cash flows. Under the Separation Agreement between the Company and Viacom Inc., the Company and Viacom Inc. have agreed to defend and indemnify the other in certain litigation in which the Company and/or Viacom Inc. is named.

12) RESTRUCTURING CHARGES

During the first quarter of 2008, the Company recorded restructuring charges of $44.9 million associated with reducing headcount in the Television and Radio segments. The restructuring charges consisted of severance costs of $34.9 million recorded in the Television segment and $10.0 million recorded in the Radio segment. As of March 31, 2008, the Company had paid $1.0 million of the Television charge and $4.4 million of the Radio charge, leaving $39.5 million of the restructuring liabilites remaining. The Company expects to substantially use these liabilities by the end of 2009.

13) FAIR VALUE MEASUREMENTS

The following table sets forth the Company's financial assets and liabilities measured at fair value on a recurring basis at March 31, 2008. These assets and liabilities have been categorized according to the three-level fair value hierarchy established by SFAS 157, which prioritizes the inputs used in measuring fair value.

(a)

Level 1 valuation is based on quoted prices for the asset in active markets.



(b)

Level 2 valuation is based on inputs that are observable other than quoted market prices in level 1, such as quoted prices for the asset or liability in inactive markets or quoted prices for similar assets or liabilities.

The fair value of investments is determined based on publicly quoted market prices in active markets. The fair value of interest rate swaps and foreign currency hedges is determined based on the present value of future cash flows using observable inputs, including interest rates, yield curves and foreign currency exchange rates. The fair value of deferred compensation is determined based on the fair value of the investments elected by employees.

14) REPORTABLE SEGMENTS

The following tables set forth the Company's financial performance by operating segment. The Company's operating segments have been determined in accordance with the Company's internal management structure, which is organized based upon products and services.

The Company presents segment operating income before depreciation and amortization ("Segment OIBDA") as the primary measure of profit and loss for its operating segments in accordance with SFAS No. 131 "Disclosures about Segments of an Enterprise and Related Information" ("SFAS 131"). The Company believes the presentation of Segment OIBDA is relevant and useful for investors because it allows investors to view segment performance in a manner similar to the primary method used by the Company's management and enhances their ability to understand the Company's operating performance.

Item 2.    Management's Discussion and Analysis of Results of Operations and Financial Condition.
(Tabular dollars in millions, except per share amounts)

Management's discussion and analysis of the results of operations and financial condition should be read in conjunction with the consolidated financial statements and related notes in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2007.

Consolidated Results of Operations

Three Months Ended March 31, 2008 versus Three Months Ended March 31, 2007

Revenues

The table below presents the Company's consolidated revenues by type for the three months ended March 31, 2008 and 2007.

			Three Months Ended March 31,
						Percentage of Total					Percentage of Total		Increase/(Decrease)
Revenues by Type			2008					2007					$			%
Advertising sales			$	2,412.9		66	%	$	2,695.2		74	%	$	(282.3	)	(10	)%
Television license fees				606.6		16			327.3		9			279.3		85
Affiliate revenues				292.5		8			276.7		7			15.8		6
Publishing				201.6		6			229.3		6			(27.7	)	(12	)
Other				140.5		4			129.3		4			11.2		9
	Total Revenues		$	3,654.1		100	%	$	3,657.8		100	%	$	(3.7	)	—	%

Advertising sales decreased $282.3 million, or 10%, to $2.41 billion for the three months ended March 31, 2008 principally reflecting the absence of the 2007 telecast of Super Bowl XLI on CBS Television Network, the timing of the Semifinals of the NCAA Men's Basketball Tournament, which aired in the second quarter of 2008 versus the first quarter of 2007, and the impact of television and radio station divestitures. These items negatively impacted the advertising sales comparison by 9% for the three months ended March 31, 2008. Television advertising sales decreased 15% due to these same three factors as well as the impact of the Writers' Guild of America ("WGA") strike, partially offset by higher political advertising sales. Radio advertising sales decreased 9% for the first quarter due to weakness in the local and national radio advertising markets and the impact of radio station divestitures. Outdoor advertising sales increased 7% for the first quarter reflecting increases of 15% in Europe and Asia and 3% in North America.

Television license fees increased $279.3 million, or 85%, to $606.6 million for the three months ended March 31, 2008 reflecting higher domestic and international syndication sales, which included the impact of a new international self-distribution arrangement for the CSI franchise, which was previously distributed by a third party, and the second-cycle syndication sale of Everybody Loves Raymond.

Affiliate revenues increased $15.8 million, or 6%, to $292.5 million for the three months ended March 31, 2008 driven by rate increases and subscriber growth at Showtime Networks and CBS College Sports Network.

Publishing revenues decreased $27.7 million, or 12%, to $201.6 million for the three months ended March 31, 2008 due to lower book sales, as best-selling titles in the first quarter of 2008 did not match contributions from prior year titles, which included The Secret by Rhonda Byrne.

Other revenues, which include home entertainment and digital media revenues and other ancillary fees for Television, Radio and Outdoor operations, increased $11.2 million, or 9%, to $140.5 million for the three months ended March 31, 2008 principally reflecting higher home entertainment revenues.

(Tabular dollars in millions, except per share amounts)

International Revenues

The Company generated approximately 20% of its total revenues from international regions for the three months ended March 31, 2008 and 11% for the three months ended March 31, 2007. The increase in international revenues for the first quarter of 2008 principally reflected the impact of the new international self-distribution arrangement for the CSI franchise.

Operating Expenses

The table below presents the Company's consolidated operating expenses by type for the three months ended March 31, 2008 and 2007.

			Three Months Ended March 31,
						Percentage of Total					Percentage of Total		Increase/(Decrease)
Operating Expenses by Type			2008					2007					$			%
Programming			$	1,061.5		45	%	$	1,164.1		49	%	$	(102.6	)	(9	)%
Production				677.8		28			584.5		24			93.3		16
Outdoor operations				296.4		12			270.8		11			25.6		9
Publishing operations				135.6		6			156.2		7			(20.6	)	(13	)
Other				215.0		9			220.2		9			(5.2	)	(2	)
	Total Operating Expenses		$	2,386.3		100	%	$	2,395.8		100	%	$	(9.5	)	—	%

Operating expenses for the three months ended March 31, 2008 decreased slightly to $2.39 billion from $2.40 billion for the three months ended March 31, 2007.

Programming expenses for the three months ended March 31, 2008 decreased $102.6 million, or 9%, to $1.06 billion primarily due to lower costs resulting from the absence of the 2007 telecast of Super Bowl XLI on CBS Television Network and the timing of the Semifinals of the NCAA Men's Basketball Tournament, which aired during the second quarter of 2008 versus the first quarter of 2007. These decreases were partially offset by higher entertainment programming costs.

Production expenses for the three months ended March 31, 2008 increased $93.3 million, or 16%, to $677.8 million due principally to costs associated with the impact of the new international self-distribution arrangement for the CSI franchise partially offset by lower costs resulting from a delay in production due to the WGA strike and the cancellation of certain television series.

Outdoor operations expenses for the three months ended March 31, 2008 increased $25.6 million, or 9%, to $296.4 million primarily due to the impact of foreign exchange rate changes and higher transit and billboard lease costs.

Publishing operations expenses for the three months ended March 31, 2008 decreased $20.6 million, or 13%, to $135.6 million primarily reflecting lower production costs and royalty expenses driven by the decrease in revenues and the mix of titles.

Other operating expenses for the three months ended March 31, 2008 decreased $5.2 million, or 2%, to $215.0 million primarily reflecting lower expenses due to the divestitures of television stations.

Results of Operations and Financial Condition (Continued)
(Tabular dollars in millions, except per share amounts)

Selling, General and Administrative Expenses

Selling, general and administrative ("SG&A") expenses, which include expenses incurred for selling and marketing costs, occupancy and back office support, decreased $44.6 million, or 7%, to $580.9 million for the three months ended March 31, 2008 from $625.5 million for the same prior-year period primarily reflecting the settlement of an international receivable claim and lower expenses due to the divestitures of television stations partially offset by higher stock-based compensation expense. Pension and postretirement benefits costs decreased $2.6 million to $34.8 million for the first quarter of 2008. SG&A expenses as a percentage of revenues were 16% and 17% for the three months ended March 31, 2008 and 2007, respectively.

Restructuring Charges

During the first quarter of 2008, the Company recorded restructuring charges of $44.9 million associated with reducing headcount in the Television and Radio segments. The restructuring charges consisted of severance costs of $34.9 million recorded in the Television segment and $10.0 million recorded in the Radio segment. As of March 31, 2008, the Company had paid $1.0 million of the Television charge and $4.4 million of the Radio charge, leaving $39.5 million of the restructuring liabilities remaining. The Company expects to substantially use these liabilities by the end of 2009.

Depreciation and Amortization

For the three months ended March 31, 2008, depreciation and amortization increased 2% to $117.8 million principally reflecting higher amortization associated with interactive businesses and higher depreciation associated with higher capital expenditures at Outdoor partially offset by lower depreciation as a result of television station divestitures.

Interest Expense

For the three months ended March 31, 2008, interest expense decreased to $138.7 million from $139.8 million. The Company had $7.13 billion and $7.73 billion of principal amounts of debt outstanding (including current maturities) at March 31, 2008 and 2007 at weighted average interest rates of 7.1% and 7.0%, respectively.

Interest Income

For the three months ended March 31, 2008, interest income decreased $21.7 million to $17.6 million principally due to lower average cash balances resulting from 2007 share repurchases.

Other Items, Net

For the three months ended March 31, 2008, "Other items, net" reflected a net loss of $.2 million consisting of losses of $4.2 million associated with securitizing accounts receivables partially offset by foreign exchange gains of $4.0 million.

For the three months ended March 31, 2007, "Other items, net" reflected a net loss of $1.5 million principally consisting of losses of $7.7 million associated with securitizing accounts receivables, partially offset by a $3.4 million pre-tax gain on the sales of radio stations and foreign exchange gains of $2.8 million.

The provision for income taxes was $151.3 million and $204.2 million for the three months ended March 31, 2008 and 2007, respectively. The Company's effective income tax rate was 37.6% for the first quarter of 2008 versus 48.7% for the same prior-year period. The provision for income taxes for the first quarter of 2007 included a tax provision of $43.5 million related to radio station divestitures.

Equity in Loss of Investee Companies, Net of Tax

Equity in loss of investee companies, net of tax, reflects the operating results of the Company's equity investments. For the three months ended March 31, 2008, equity in loss of investee companies, net of tax, increased $5.3 million to a loss of $7.2 million primarily reflecting operating losses for the Company's investment in The CW.

Minority Interest, Net of Tax

Minority interest primarily represents the minority ownership of certain international entities.

Net Earnings

The Company reported net earnings of $244.3 million for the three months ended March 31, 2008 versus $213.5 million for the three months ended March 31, 2007.

The Company presents Segment OIBDA as the primary measure of profit and loss for its operating segments in accordance with Statement of Financial Accounting Standards ("SFAS") No. 131 "Disclosures about Segments of an Enterprise and Related Information" ("SFAS 131"). The Company believes the presentation of Segment OIBDA is relevant and useful for investors because it allows investors to view segment performance in a manner similar to the primary method used by the Company's management and enhances their ability to understand the Company's operating performance. The reconciliation of Segment OIBDA to the Company's consolidated Net Earnings is presented in Note 14 (Reportable Segments) to the consolidated financial statements.

Management's Discussion and Analysis of
Results of Operations and Financial Condition (Continued)
(Tabular dollars in millions, except per share amounts)

Television (CBS Television Network, CBS Television Stations, CBS Paramount Network Television, CBS Television Distribution, Showtime Networks and CBS College Sports Network)

(Contributed 71% to consolidated revenues for the three months ended March 31, 2008 and 70% for the comparable prior-year period.)

For the three months ended March 31, 2008, Television revenues increased 1% to $2.60 billion from $2.57 billion for the same prior-year period primarily due to higher television license fees and affiliate revenues, partially offset by lower advertising sales. Television license fees increased 85% for the first quarter of 2008 versus the same prior-year period primarily due to higher domestic and international syndication sales, which included the impact of the new international self-distribution arrangement for the CSI franchise, which was previously distributed by a third party, and the second-cycle syndication sale of Everybody Loves Raymond. Affiliate revenues increased 6% driven by rate increases and subscriber growth at Showtime Networks and CBS College Sports Network. Revenue comparability during the first quarter of 2008 was negatively impacted by the absence of the 2007 telecast of Super Bowl XLI on CBS Television Network, the timing of the Semifinals of the NCAA Men's Basketball Tournament, which aired in the second quarter of 2008 versus the first quarter of 2007, and television station divestitures in 2007. These items negatively impacted the Television advertising sales comparison by 12%. Advertising sales decreased 15% for the first quarter of 2008 primarily due to the aforementioned three factors and the impact of the WGA strike, which was settled in February 2008, partially offset by higher political advertising sales.

For the three months ended March 31, 2008, Television operating income increased 15% to $402.1 million and OIBDA increased 13% to $449.5 million for the first quarter of 2008 primarily due to higher profits from syndication sales, principally from the CSI franchise and the sale of Everybody Loves Raymond, and higher affiliate revenues, partially offset by restructuring charges of $34.9 million incurred during the first quarter of 2008 and higher stock-based compensation expense. Television results included stock-based compensation expense of $16.3 million and $10.3 million for the first quarter of 2008 and 2007, respectively.

On January 10, 2008, the Company completed the sale of seven of its owned television stations in Austin, Salt Lake City, Providence and West Palm Beach to Cerberus Capital Management, L.P. for $185 million.

Results of Operations and Financial Condition (Continued)
(Tabular dollars in millions, except per share amounts)

Radio (CBS Radio)

(Contributed 10% to consolidated revenues for the three months ended March 31, 2008 and 11% for the comparable prior-year period.)

For the three months ended March 31, 2008, Radio revenues decreased 9% to $363.5 million from $397.5 million for the same prior-year period reflecting weakness in the local and national radio advertising markets and the impact of radio station divestitures. The station divestitures negatively impacted the Radio revenue comparison by 2% for the three months ended March 31, 2008. These decreases were partially offset by the recognition of $10.4 million of revenue associated with the Company's former agreements with Westwood One, Inc. ("Westwood One"). On March 3, 2008, the new agreements between CBS Radio and Westwood One became effective, which include, among others, agreements relating to the termination of management and representation arrangements, and modification and extension of certain arrangements involving compensation to the Company of affiliation and other fees, the provision of radio programming (principally news and traffic) by Westwood One to CBS Radio and the distribution by Westwood One of CBS Radio News. Prior to March 3, 2008, Radio also received consideration for management services provided to Westwood One. Radio's revenues from Westwood One totaled $23.0 million for the three months ended March 31, 2008 and $13.2 million for the same prior-year period.

For the three months ended March 31, 2008, Radio operating income decreased 27% to $115.0 million and OIBDA decreased 26% to $122.3 million due to lower advertising sales, the absence of profits from divested stations and restructuring charges of $10.0 million incurred during the first quarter of 2008. These decreases were partially offset by the aforementioned $10.4 million of revenues relating to the Company's former agreements with Westwood One. Radio results included stock-based compensation expense of $3.8 million for the three months ended March 31, 2008 versus $3.4 million for the same prior-year period.

(Tabular dollars in millions, except per share amounts)

Outdoor (CBS Outdoor)

(Contributed 14% to consolidated revenues for the three months ended March 31, 2008 and 13% for the comparable prior-year period.)

For the three months ended March 31, 2008, Outdoor revenues increased 7% to $496.9 million from $462.3 million for the same prior-year period principally reflecting growth of 15% in Europe and Asia due to favorable foreign exchange rate fluctuations and growth in the U.K. North America revenues increased 3% for the quarter, reflecting growth of 1% in the U.S. billboards business, 11% in Canada and 10% in Mexico partially offset by a decrease of 1% in U.S. transit and displays. Revenue growth in North America was negatively impacted by the non-renewal of two major municipal contracts in Toronto and San Francisco, which reduced the revenue growth in North America by 2% for the quarter. The favorable impact of foreign exchange rate changes on total Outdoor revenues was approximately $20 million for the three months ended March 31, 2008. Approximately 50% and 47% of Outdoor revenues were generated from international regions for the three months ended March 31, 2008 and 2007, respectively.

For the three months ended March 31, 2008, Outdoor operating income decreased 6% to $44.1 million and OIBDA increased 1% to $101.5 million. The increase in OIBDA reflected growth in Europe and Asia partially offset by a decline in North America. Europe and Asia OIBDA increased 48% to $10.2 million driven by the revenue growth. North America OIBDA decreased 2% to $91.3 million due primarily to the aforementioned non-renewal of municipal contracts as well as higher billboard lease and transit costs. The decrease in Outdoor operating income reflects higher depreciation expense associated with recent capital expenditures. Operating income for North America decreased 6% to $45.0 million and Europe and Asia remained flat with an operating loss of $.9 million. Outdoor results included stock-based compensation expense of $1.5 million for the three months ended March 31, 2008 versus $1.1 million for the same prior-year period.

On April 23, 2008, the Company acquired International Outdoor Advertising Group (IOA), the leading out-of-home advertising company in South America, for $110 million in cash.

Results of Operations and Financial Condition (Continued)
(Tabular dollars in millions, except per share amounts)

Publishing (Simon & Schuster)

(Contributed 6% to consolidated revenues for each of the three months ended March 31, 2008 and March 31, 2007.)

For the three months ended March 31, 2008, Publishing revenues decreased 12% to $201.6 million from $229.3 million for the same prior-year period due to lower book sales, as best-selling titles in the first quarter of 2008, including Duma Key by Stephen King, Where Are You Now? by Mary Higgins Clark and Change of Heart by Jodi Picoult did not match contributions from prior year titles, which included The Secret by Rhonda Byrne.

For the three months ended March 31, 2008, Publishing operating income decreased 32% to $14.6 million and OIBDA decreased 28% to $17.1 million. These decreases reflected the decline in revenues partially offset by lower royalty expenses, production costs and selling and advertising expenses which were driven by the revenue decline and the mix of titles. Publishing results included stock-based compensation expense of $1.0 million for the three months ended March 31, 2008 versus $.7 million for the same prior-year period.

Financial Position

Current assets increased $960.9 million to $6.99 billion at March 31, 2008 from $6.03 billion at December 31, 2007 primarily due to increases in cash and cash equivalents and receivables, partially offset by a decrease in programming and other inventory. The increase in cash and cash equivalents of $912.0 million principally reflected cash flows from operations. The increase in receivables is due to the impact of the new international self-distribution arrangement for the CSI franchise and the decrease in programming and other inventory reflects the timing of sports programming payments and the impact of the WGA strike. The allowance for doubtful accounts as a percentage of receivables decreased to 4.5% at March 31, 2008 versus 5.0% at December 31, 2007 reflecting higher gross accounts receivables at March 31, 2008, resulting from the new international self-distribution arrangement for the CSI franchise.

Net property and equipment of $2.89 billion at March 31, 2008 decreased $28.5 million from $2.92 billion at December 31, 2007, primarily reflecting depreciation expense of $92.2 million and television station divestitures of $24.5 million, partially offset by capital expenditures of $88.8 million.

(Tabular dollars in millions, except per share amounts)

Goodwill increased $28.6 million to $18.48 billion at March 31, 2008 from $18.45 billion at December 31, 2007, primarily reflecting foreign currency translation adjustments, partially offset by television station divestitures of $35.2 million.

Intangible assets, principally consisting of FCC licenses, leasehold agreements and franchise agreements, decreased by $120.3 million to $9.96 billion at March 31, 2008 from $10.08 billion at December 31, 2007, primarily due to television station divestitures of $98.9 million and amortization expense of $25.6 million.

Current liabilities increased $332.3 million to $4.74 billion at March 31, 2008 from $4.40 billion at December 31, 2007, primarily due to the impact of the new international self-distribution arrangement for the CSI franchise and an advance payment received from a third party distributor for home entertainment products.

Cash Flows

Cash and cash equivalents increased by $912.0 million for the three months ended March 31, 2008. The change in cash and cash equivalents was as follows:

Operating Activities.    Cash provided by operating activities of $1.03 billion for the three months ended March 31, 2008 increased $178.8 million, or 21%, from $848.0 million for the same prior-year period primarily reflecting lower television production payments and an advance payment received from a third party distributor for home entertainment products.

Cash paid for income taxes for the three months ended March 31, 2008 was $47.5 million versus $41.3 million for the three months ended March 31, 2007.

Investing Activities.    Cash provided by investing activities of $42.6 million for the three months ended March 31, 2008 principally reflected proceeds of $185.0 million from television station divestitures partially offset by capital expenditures of $88.8 million and acquisitions of $48.4 million, primarily consisting of additional payments for the 2007 acquisition of Last.fm and the acquisition of outdoor advertising properties. Cash provided by investing activities of $277.9 million for the three months ended March 31, 2007 principally reflected proceeds from dispositions of $243.7 million, primarily from radio station divestitures, and net receipts from Viacom Inc. relating to the Separation of $188.5 million. These increases were partially offset by capital expenditures of $95.1 million and acquisitions of $28.1 million, primarily consisting of the acquisition of outdoor advertising properties and investments in several new interactive initiatives.

Financing Activities.    Cash used for financing activities of $157.4 million for the three months ended March 31, 2008 principally reflected dividend payments of $168.8 million, partially offset by proceeds from the exercise of stock options of $30.4 million. Cash used for financing activities of $821.9 million for the three months ended March 31, 2007 principally reflected the purchase of Company Common Stock for $1.42 billion and dividend payments of $153.9 million, partially offset by net proceeds from the issuance of senior notes of $678.0 million and proceeds from the exercise of stock options of $75.6 million.

Cash Dividends

On February 21, 2008, the Company announced a quarterly cash dividend of $.25 per share on its Class A and Class B Common Stock payable on April 1, 2008. The total dividend was $171.2 million of which $167.0 million was paid on April 1, 2008 and $4.2 million was accrued to be paid upon vesting of RSUs and restricted shares. During the first quarter of 2008, the Company paid $168.8 million for the dividend declared on November 1, 2007 and for dividend payments on RSUs that vested during the first quarter of 2008. Dividend declarations during 2008 and 2007 were recorded as a reduction to additional paid-in capital as the Company had an accumulated deficit balance.

On April 29, 2008, the Company announced an 8% increase to its quarterly cash dividend to $.27 from $.25 per share. The dividend is payable on July 1, 2008 to stockholders of record as of June 3, 2008.

Purchase of Company Stock

In January 2008, the Company received 6.0 million shares of CBS Corp. Class B Common Stock upon settlement of a 2007 accelerated share repurchase transaction.

Capital Structure

The following table sets forth the Company's long-term debt.

(a)

As of March 31, 2008 and December 31, 2007, the senior debt balances included (i) a net unamortized premium of $25.5 million and $26.2 million, respectively, and (ii) a change in the carrying value of the debt relating to fair value hedges of $43.4 million and $(5.0) million, respectively.



(b)

Included in "Liabilities of discontinued operations" on the Consolidated Balance Sheets.

The senior debt of CBS Corp. is fully and unconditionally guaranteed by its wholly owned subsidiary, CBS Operations Inc. Senior debt in the amount of $52.2 million of the Company's wholly owned subsidiary, CBS Broadcasting Inc., is not guaranteed.

Credit Facility

As of March 31, 2008, the Company had a $3.0 billion revolving credit facility due December 2010 (the "Credit Facility"), primarily to support commercial paper borrowings. At March 31, 2008, the Company

-35-

---

Management's Discussion and Analysis of

(Tabular dollars in millions, except per share amounts)

had no commercial paper borrowings and was in compliance with all covenants under the Credit Facility, including the requirement that the Company maintain a minimum coverage ratio. As of March 31, 2008, the remaining availability under this Credit Facility, net of outstanding letters of credit, was $2.81 billion.

Accounts Receivable Securitization Program

As of March 31, 2008, the Company had $550.0 million outstanding under its revolving accounts receivable securitization program. The program results in the sale of receivables on a non-recourse basis to unrelated third parties on a one-year renewable basis, thereby reducing accounts receivable on the Company's Consolidated Balance Sheet. The Company entered into this arrangement because it provides an additional source of liquidity. Proceeds from this program were used to reduce outstanding borrowings. The terms of the revolving securitization arrangement require that the receivable pools subject to the program meet certain performance ratios. As of March 31, 2008, the Company was in compliance with the required ratios under the receivable securitization program.

During the three months ended March 31, 2008 and 2007, proceeds from collections of securitized accounts receivables of $681.1 million and $670.1 million, respectively, were reinvested in the revolving receivable securitization program. The net loss associated with securitizing the program's accounts receivables was $4.2 million and $7.7 million for the three months ended March 31, 2008 and 2007, respectively.

Liquidity and Capital Resources

The Company believes that its operating cash flows ($1.03 billion for the three months ended March 31, 2008), cash and cash equivalents ($2.26 billion at March 31, 2008), borrowing capacity under its committed bank facility (which consisted of an unused revolving Credit Facility of $2.81 billion at March 31, 2008), and access to capital markets are sufficient to fund its operating needs, including commitments and contingencies, capital and investing commitments, and dividend and other financing requirements for the foreseeable future. The funding for commitments to purchase sports programming rights, television and film programming, and talent contracts will come primarily from cash flow from operations.

The Company continually projects anticipated cash requirements, which include capital expenditures, dividends, acquisitions, and principal payments on its outstanding indebtedness, as well as cash flows generated from operating activities available to meet these needs. Any additional net cash funding requirements are financed with short-term borrowings (primarily commercial paper) and long-term debt. Commercial paper borrowings, which also accommodate day-to-day changes in funding requirements, are backed by the Credit Facility which may be utilized in the event that commercial paper borrowings are not available. The Company's credit position affords sufficient access to the capital markets to meet the Company's financial requirements.

The Company anticipates that future debt maturities will be funded with cash and cash equivalents and cash flows generated from operating activities and other debt financing. There are no provisions in any of the Company's material financing agreements that would cause an acceleration of the obligation in the event of a downgrade in the Company's debt ratings.

The Company filed a shelf registration statement with the Securities and Exchange Commission registering debt securities, preferred stock and warrants of CBS Corp. that may be issued for aggregate

-36-

Management's Discussion and Analysis of

(Tabular dollars in millions, except per share amounts)

gross proceeds of $5.0 billion. The registration statement was first declared effective on January 8, 2001. The net proceeds from the sale of the offered securities may be used by CBS Corp. for general corporate purposes, including repayment of borrowings, working capital and capital expenditures, or for such other purposes as may be specified in the applicable prospectus supplement. To date, the Company has issued $3.085 billion of securities under the shelf registration statement.

Off-Balance Sheet Arrangements

Prior to the Separation of Former Viacom into CBS Corp. and Viacom Inc., Former Viacom had entered into guarantees with respect to obligations related to Blockbuster Inc. ("Blockbuster"), including certain Blockbuster store leases; Famous Players theater leases; certain UCI theater leases; and certain theater leases related to W.F. Cinema Holdings L.P. and Grauman's Theatres LLC. In connection with the Separation, Viacom Inc. has agreed to indemnify the Company with respect to these guarantees. In addition, the Company and Viacom Inc. have agreed to indemnify each other with respect to certain other matters pursuant to the Separation Agreement between the parties.

The Company has indemnification obligations with respect to letters of credit and surety bonds primarily used as security against non-performance in the normal course of business. At March 31, 2008, the outstanding letters of credit and surety bonds approximated $406.1 million and are not recorded on the Consolidated Balance Sheet.

In the course of its business, the Company both provides and receives indemnities which are intended to allocate certain risks associated with business transactions. Similarly, the Company may remain contingently liable for various obligations of a business that has been divested in the event that a third party does not live up to its obligations under an indemnification obligation. The Company records a liability for its indemnification obligations and other contingent liabilities when probable under generally accepted accounting principles.

Legal Matters

Indecency Regulation.    In March 2006, the FCC released certain decisions relating to indecency complaints against certain of the Company's owned television stations and affiliated stations. The FCC ordered the Company to pay a forfeiture of $550,000 in the proceeding relating to the broadcast of a Super Bowl half-time show by the Company's television stations. In May 2006, the FCC denied the Company's petition for reconsideration. In July 2006, the Company filed a Petition for Review of the forfeiture with the U.S. Court of Appeals for the Third Circuit and paid the $550,000 forfeiture in order to facilitate the Company's ability to bring the appeal. Oral argument was heard in September 2007. The Company is awaiting the court's decision.

In March 2006, the FCC also notified the Company and certain affiliates of the CBS Television Network of apparent liability for forfeitures relating to a broadcast of the program Without a Trace. The FCC proposed to assess a forfeiture of $32,500 against each of these stations, totaling $260,000 for the Company's owned stations. The Company is contesting the FCC decision and the proposed forfeitures.

In June 2007, the U.S. Court of Appeals for the Second Circuit vacated the FCC's November 2006 finding that the broadcast of fleeting and isolated expletives on another broadcast network was indecent and remanded the case to the FCC. On March 17, 2008, the U.S. Supreme Court granted the FCC's petition to review the U.S. Court of Appeals for the Second Circuit's decision.

(Tabular dollars in millions, except per share amounts)

Additionally, the Company, from time to time, has received and may receive in the future letters of inquiry from the FCC prompted by complaints alleging that certain programming on the Company's broadcasting stations included indecent material.

Claims Related to Former Businesses: Asbestos, Environmental and Other.    The Company is a defendant in lawsuits claiming various personal injuries related to asbestos and other materials, which allegedly occurred principally as a result of exposure caused by various products manufactured by Westinghouse, a predecessor, generally prior to the early 1970s. Westinghouse was neither a producer nor a manufacturer of asbestos. The Company is typically named as one of a large number of defendants in both state and federal cases. In the majority of asbestos lawsuits, the plaintiffs have not identified which of the Company's products is the basis of a claim. Claims against the Company in which a product has been identified principally relate to exposures allegedly caused by asbestos-containing insulating material in turbines sold for power-generation, industrial and marine use, or by asbestos containing grades of decorative micarta, a laminate used in commercial ships.

Claims are frequently filed and/or settled in large groups, which may make the amount and timing of settlements, and the number of pending claims, subject to significant fluctuation from period to period. The Company does not report as pending those claims on inactive, stayed, deferred or similar dockets which some jurisdictions have established for claimants who allege minimal or no impairment. As of March 31, 2008, the Company had pending approximately 72,870 asbestos claims, as compared with approximately 72,120 as of December 31, 2007 and approximately 72,510 as of March 31, 2007. Of the claims pending as of March 31, 2008, approximately 40,950 were pending in state courts, 28,310 in federal courts and, additionally, approximately 3,610 were third party claims pending in state courts. During the first quarter of 2008, the Company received approximately 1,600 new claims and closed or moved to an inactive docket approximately 850 claims. The Company reports claims as closed when it becomes aware that a dismissal order has been entered by a court or when the Company has reached agreement with the claimants on the material terms of a settlement. Settlement costs depend on the seriousness of the injuries that form the basis of the claim, the quality of evidence supporting the claims and other factors. The Company's total costs for the years 2007 and 2006 for settlement and defense of asbestos claims after insurance recoveries and net of tax benefits were approximately $17.5 million and $5.7 million, respectively. The Company's costs for settlement and defense of asbestos claims may vary year to year as insurance proceeds are not always recovered in the same period as the insured portion of the expenses.

Filings include claims for individuals suffering from mesothelioma, a rare cancer, the risk of which is allegedly increased primarily by exposure to asbestos; lung cancer, a cancer which may be caused by various factors, one of which is alleged to be asbestos exposure; other cancers, and conditions that are substantially less serious, including claims brought on behalf of individuals who are asymptomatic as to an allegedly asbestos-related disease. Claims identified as cancer remain a small percentage of asbestos claims pending at March 31, 2008. In a substantial number of the pending claims, the plaintiff has not yet identified the claimed injury. The Company believes that its reserves and insurance are adequate to cover its asbestos liabilities.

The Company from time to time receives claims from federal and state environmental regulatory agencies and other entities asserting that it is or may be liable for environmental cleanup costs and related damages principally relating to historical and predecessor operations of the Company. In addition, the Company from time to time receives personal injury claims including toxic tort and product liability claims (other than asbestos) arising from historical operations of the Company and its predecessors.

Management's Discussion and Analysis of
Results of Operations and Financial Condition (Continued)
(Tabular dollars in millions, except per share amounts)

General.    On an ongoing basis, the Company defends itself in numerous lawsuits and proceedings and responds to various investigations and inquiries from federal, state and local authorities (collectively, "litigation"). Litigation is inherently uncertain and always difficult to predict. However, based on its understanding and evaluation of the relevant facts and circumstances, the Company believes that the above-described legal matters and other litigation to which it is a party are not likely, in the aggregate, to have a material adverse effect on its results of operations, financial position or cash flows. Under the Separation Agreement between the Company and Viacom Inc., the Company and Viacom Inc. have agreed to defend and indemnify the other in certain litigation in which the Company and/or Viacom Inc. is named.

Related Parties

National Amusements, Inc.    National Amusements, Inc. ("NAI") is the controlling stockholder of CBS Corp. Mr. Sumner M.

Class A Common Stock representing approximately 80% of the voting power of all classes of CBS Corp.'s Common Stock, and owned approximately 13% of CBS Corp.'s Class A Common Stock and Class B Common Stock on a combined basis.

Viacom Inc.    CBS Corp., through its normal course of business, is involved in transactions with companies owned by or affiliated with Viacom Inc. CBS Corp., through its Television segment, licenses its television products to Viacom Inc., primarily MTV Networks and BET.

CBS Corp., through Showtime Networks, pays license fees to Viacom Inc., primarily Paramount Pictures, for motion picture programming. These license fees are initially recorded as programming inventory and amortized over the shorter of the life of the license agreement or projected useful life of the programming. In addition, CBS Corp. places advertisements with various subsidiaries of Viacom Inc. The total amounts from these transactions were $3.8 million and $47.0 million for the three months ended March 31, 2008 and 2007, respectively.

Results of Operations and Financial Condition (Continued)
(Tabular dollars in millions, except per share amounts)

The following table presents the amounts due from or due to Viacom Inc. in the normal course of business as reflected on CBS Corp.'s Consolidated Balance Sheets:

Other Related Parties    The Company owns approximately 16% of Westwood One. The termination, modification and/or extension of agreements entered into by Westwood One and CBS Radio on October 2, 2007 became effective at a closing on March 3, 2008. The new agreements include an amended and restated Technical Services Agreement, News Programming Agreement, Trademark License Agreement and affiliation agreements. Pursuant to the affiliation agreements, certain of the Company's radio stations air programs and/or commercials supplied by Westwood One and, in return, the stations receive affiliation fees and certain programming cost reimbursements. As of March 3, 2008, the previous Representation Agreement and Management Agreement between the parties were terminated resulting in the termination of the Company's management role with Westwood One, the relinquishment of any representation on the Westwood One board of directors and termination of the Company's outstanding warrants to acquire shares of Westwood One common stock, which were out-of-the-money. CBS Television also has arrangements to provide news and sports programming to Westwood One. The Company's revenues from Westwood One were $27.2 million and $18.3 million for the three months ended March 31, 2008 and 2007, respectively.

Prior to March 3, 2008, the Company accounted for its investment in Westwood One under the equity method of accounting. As a result of the new agreements, the Company's investment in Westwood One, totaling $33.6 million at March 31, 2008, is being accounted for as an investment pursuant to the provisions of SFAS No. 115, "Accounting for Certain Investments in Debt and Equity Securities", with any unrealized gains or losses recorded within other comprehensive income (loss). During the three months ended March 31, 2008, unrealized losses of $.8 million were recorded in other comprehensive loss relating to the Company's investment in Westwood One.

The Company owns 50% of The CW, which is accounted for by the Company as an equity investment. CBS Corp., through the Television segment, licenses its television products to The CW resulting in total revenues of $13.7 million and $32.9 million for the three months ended March 31, 2008 and 2007, respectively.

The Company, through the normal course of business, is involved in transactions with other related parties that have not been material in any of the periods presented.

Adoption of New Accounting Standards

Effective January 1, 2008, the Company adopted Financial Accounting Standards Board ("FASB") SFAS No. 157, "Fair Value Measurements" ("SFAS 157") for its financial assets and liabilities. In February 2008, the FASB issued FASB Staff Position ("FSP") No. FAS 157-2, "Effective Date of FASB Statement No. 157", which delays the effective date of SFAS 157 for nonfinancial assets and liabilities, except for items that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually), to fiscal years beginning after November 15, 2008 and interim periods within those fiscal years. SFAS 157 establishes a framework for measuring fair value under generally accepted accounting principles and expands disclosures about fair value measurement. The adoption of SFAS 157 on January 1, 2008 did not have a material effect on the Company's consolidated financial statements.

In February 2007, the FASB issued SFAS No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities – Including an amendment of FASB Statement No. 115" ("SFAS 159") effective as of the beginning of the first fiscal year that begins after November 15, 2007. SFAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value with changes in fair value recognized in earnings for each reporting period. The adoption of SFAS 159 on January 1, 2008 did not have any effect on the Company's consolidated financial statements as the Company did not elect any eligible items for fair value measurement.

Recent Pronouncements

In March 2008, the FASB issued SFAS No. 161, "Disclosures about Derivative Instruments and Hedging Activities – an amendment of FASB Statement No. 133" ("SFAS 161") effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. SFAS 161 requires an entity to provide enhanced disclosures about derivative instruments and hedging activities.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), "Business Combinations" ("SFAS 141R"), effective 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, 2008. SFAS 141R establishes principles and requirements for how an acquirer recognizes and measures identifiable assets acquired, liabilities assumed, any noncontrolling interest in the acquiree and goodwill. SFAS 141R also expands disclosure requirements for business combinations.

In December 2007, the FASB issued SFAS No. 160, "Noncontrolling Interests in Consolidated Financial Statements – an amendment of ARB No. 51" ("SFAS 160") effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. SFAS 160 establishes accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. The adoption of SFAS 160 is not expected to have a material effect on the Company's consolidated financial statements.

This quarterly report on Form 10-Q, including "Item 2 - Management's Discussion and Analysis of Results of Operations and Financial Condition," contains both historical and forward-looking statements. All statements other than statements of historical fact are, or may be deemed to be, forward-looking statements within the meaning of section 27A of the Securities Act of 1933 and section 21E of the Securities Exchange Act of 1934. These forward-looking statements are not based on historical facts, but rather reflect the Company's current expectations concerning future results and events. These forward-looking statements generally can be identified by the use of statements that include phrases such as "believe," "expect," "anticipate," "intend," "plan," "foresee," "likely," "will" or other similar words or phrases. Similarly, statements that describe the Company's objectives, plans or goals are or may be forward-looking statements. These forward-looking statements involve known and unknown risks, uncertainties and other factors that are difficult to predict and which may cause the actual results, performance or achievements of the Company to be different from any future results, performance and achievements expressed or implied by these statements. These risks, uncertainties and other factors include, among others: advertising market conditions generally; changes in the public acceptance of the Company's programming; changes in technology and its effect on competition in the Company's markets; changes in the federal communications laws and regulations; the impact of piracy on the Company's products; the impact of consolidation in the market for the Company's programming; the impact of union activity, including possible strikes or work stoppages or the Company's inability to negotiate favorable terms for contract renewals; other domestic and global economic, business, competitive and/or regulatory factors affecting the Company's businesses generally; and other factors described in the Company's news releases and filings made under the securities laws, including, among others, those set forth under "Item 1A. Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2007 and in our Quarterly Reports on Form 10-Q. There may be additional risks, uncertainties and factors that the Company does not currently view as material or that are not necessarily known. The forward-looking statements included in this document are made as of the date of this document and the Company does not have any obligation to publicly update any forward-looking statements to reflect subsequent events or circumstances.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

Item 4. Controls and Procedures.

The Company's chief executive officer and chief financial officer have concluded that, as of the end of the period covered by this report, the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934, as amended) were effective, based on the evaluation of these controls and procedures required by Rule 13a-15(b) or 15d-15(b) of the Securities Exchange Act of 1934, as amended.

No change in the Company's internal control over financial reporting occurred during the Company's last fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1A. Risk Factors.

The following updates the corresponding risk factor included in the Company's Annual Report on Form 10-K for the year ended December 31, 2007.

The Company Could Be Adversely Affected by Strikes and Other Union Activity

The Company and its suppliers engage the services of writers, directors, actors and other talent, trade employees and others who are subject to collective bargaining agreements. If the Company or its suppliers are unable to renew expiring collective bargaining agreements, it is possible that the affected unions could take action in the form of strikes or work stoppages. Such actions, higher costs in connection with these agreements or a significant labor dispute could adversely affect the Company's television and radio businesses by causing delays in the production of the Company's television or radio programming or the Company's outdoor business by disrupting its ability to place advertising on outdoor faces. The entertainment businesses' collective bargaining agreements with each of the Screen Actors Guild ("SAG") and American Federation of Television and Radio Artists covering performers expire on June 30, 2008 and negotiations for a new agreement have begun between SAG and the Alliance of Motion Picture and Television Producers. Depending on their duration, strikes or work stoppages could have an adverse effect on the Company's revenues and operating income.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

During the first quarter of 2008, the Company did not purchase any shares under its publicly announced share purchase programs which have remaining authorization of $649.4 million. In January 2008, the Company received 6.0 million shares of CBS Corp. Class B Common Stock upon settlement of a 2007 publicly announced accelerated share repurchase transaction.
