These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Plan as of December 31, 1997 and 1996, and the changes in its net assets available for plan benefits for the year ended December 31, 1997, in conformity with generally accepted accounting principles. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held for investment purposes is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The fund information in the statements of net assets available for plan benefits as of December 31, 1997 and 1996 and the statement of changes in net assets available for plan benefits for the year ended December 31, 1997 is presented for purposes of additional analysis rather than to present the net assets available for plan benefits and changes in net assets available for plan benefits of each fund. The supplemental schedule and the fund information have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.

ACNEILSEN CORPORATE SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS Note 1. Plan Description ACNielsen Corporation ("ACNielsen" or the "Company") began operating as an independent, publicly-held company on November 1, 1996 (the "Distribution Date") as a result of the distribution on that date by The Dun & Bradstreet Corporation ("D&B") of the Company's $.01 par value Common Stock. As part of a reorganization of its businesses, D&B also distributed all of the outstanding common stock of Cognizant Corporation ("Cognizant") on the Distribution Date. The ACNielsen Corporation Savings Plan (the "Plan") was adopted, effective November 1, 1996, for all U.S. employees of ACNielsen. In December 1996 and January 1997, assets from the Profit Participation Plan of The Dun & Bradstreet Corporation held in the accounts of ACNielsen employees were transferred to the Plan to the extent those employees so elected. Fidelity Management Trust Company replaced Bankers Trust Company as the trustee of the Plan effective April 1, 1997. As a result of the assignment of the new trustee and the establishment of a master trust between Fidelity Management Trust Company, the ACNielsen Corporation Savings Plan and the ACNielsen Corporation Employee Stock Ownership Plan, participants have new investment options beginning April 1, 1997. The following summary of major Plan provisions in effect for the Plan year is provided for general information purposes only. Participants should refer to the Plan document for more complete information. General The Plan is a defined contribution plan and is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). All U.S. employees, except leased employees and employees whose terms and conditions of employment are the subject of a collective bargaining agreement, become eligible to participate in the Plan on their employment commencement date. Contributions Participants contribute to the Plan by authorizing payroll deductions of a stated whole percentage subject to a maximum of 16% of the participant's covered compensation as defined in the Plan. A participant's contributions under the Plan may be made in the form of contributions from after-tax earnings and/or contributions from before-tax earnings, which have the effect of reducing current taxable earnings for federal income tax purposes. A participant's aggregate before- and after- tax contributions may not exceed 16% of the participant's covered compensation, subject to an overall limit on contributions imposed by the Internal Revenue Code. For 1997, the Internal Revenue Code limit on before-tax contributions was $9,500. To comply with certain provisions of the Internal Revenue Code, the Plan limits maximum covered compensation as defined by the Secretary of the Treasury. The maximum covered compensation for purposes of determining a participant's contributions under the Plan for 1997 was $160,000. Participant Accounts Each participant's account is credited with the participant's contribution and account earnings. Vesting Participants are immediately vested in their contributions plus actual earnings thereon. Investment Options Prior to April 1, 1997, upon enrollment in the Plan, a participant could direct his or her contributions in 10% increments in any of the four following investment options, with no more than 50% invested in the ACNielsen Common Stock Fund. No additional amounts could be contributed to the Legacy Fund. Equity Index Fund - The Equity Index Fund was invested in the common stock of all or a significant portion of the companies included in the Standard & Poor's 500 Stock Index and approved short-term instruments to provide for liquidity. The objective of the fund was to obtain a total rate of return (dividends plus market gains or losses) similar to that of the Standard & Poor's 500 Stock Index, although there was no assurance that this objective would be achieved. The Equity Index Fund was managed by BZW Barclays Global Investors which had exclusive responsibility for investment management of the fund. ACNielsen Common Stock Fund - The ACNielsen Common Stock Fund was invested in the common stock of ACNielsen Corporation and approved short-term instruments to provide for liquidity. Bankers Trust, the Plan's trustee, prior to April 1, 1997, purchased ACNielsen common stock for this fund in the open market in accordance with a nondiscretionary purchasing program. The trustee could also purchase or accept authorized but as yet unissued shares of ACNielsen common stock, or shares held as treasury shares, from ACNielsen. Special Fixed Income Fund - The Special Fixed Income Fund was comprised of Fidelity's Managed Income Portfolio and individual investment contracts (ICs) with one or more insurance companies previously selected by D&B. The objective of the Special Fixed Income Fund was to provide a competitive level of income over time while preserving the value of the investment. As the existing ICs mature, the funds would be invested with Fidelity's Managed Income Portfolio. The Managed Income Portfolio purchased investment contracts offered by major insurance companies and other approved short-term instruments to provide for liquidity. Some investment contracts were purchased along with fixed income securities or units of bond funds which invest in such securities. New contributions and transfers to the Special Fixed Income Fund were invested in the Managed Income Portfolio which was managed by Fidelity Management Trust Company. Long Term Bond Index Fund - The Long Term Bond Index Fund was invested in fixed income securities, including, but not limited to, U.S. government and agency securities, mortgage-backed securities issued by agencies of the U.S. government, investment grade corporate securities and other short-term investments to provide for liquidity. The objective of the fund was to obtain a total rate of return (interest plus market gains and losses) similar to that of the Lehman Brothers Aggregate Bond Index, although there was no assurance that this objective would be achieved. The Long Term Bond Index Fund was managed by BZW Barclays Global Investors. The Long Term Bond Index Fund assets were managed as part of the BZW Barclays U.S. Debt Index Fund, a collective trust fund which had the objective of replicating the performance of the Lehman Brothers Aggregate Bond Index. Legacy Fund - The Legacy Fund replaced the Dun & Bradstreet Common Stock Fund in the Profit Participation Plan of The Dun & Bradstreet Corporation and was available only to former participants in that plan. At the time of the D&B reorganization, the Dun & Bradstreet Common Stock Fund became a fund consisting of shares of ACNielsen, Cognizant and D&B. Participants could not make additional contributions or transfers to this fund. Participants were able to reallocate their entire account balances in multiples of 10% among the funds on a monthly basis subject to the 50% limit on investments in the ACNielsen Common Stock Fund. Participants could not elect transfers into the Legacy Fund. On and after April 1, 1997 (with Fidelity Management Trust Company replacing Bankers Trust as the new trustee) and upon enrollment in the Plan, a participant may direct his or her contributions in 1% increments in any of eleven investment options, with no more than 50% invested in the ACNielsen Common Stock Fund. No additional amounts may be contributed to the Legacy Fund. Managed Income Fund - The Managed Income Fund is a combination of Fidelity's Managed Income Portfolio I and investment contracts previously purchased by this plan. It is not a mutual fund. The goal of the fund is to provide a competitive level of income over time while preserving the investment. The Portfolio purchases investment contracts offered by major insurance companies and other approved financial institutions and short-term investments to provide for liquidity needs. Some investment contracts (synthetic wrappers) are purchased in conjunction with the purchase of fixed income securities or units of bond funds which invest in such securities. As previous investment contracts mature, all proceeds will be invested in the Managed Income Portfolio. Growth & Income Fund - The Growth & Income Fund is a growth and income mutual fund. The goal of the fund is to provide high total return through a combination of current income and capital appreciation. The fund invests mainly in U.S. and foreign stocks. It selects companies that currently pay dividends and carry the potential for increased earnings. The fund may also invest in bonds. Blue Chip Fund - The Blue Chip Fund is a growth mutual fund. The goal of the fund is to increase the value of the investment over the long term through capital growth. The fund invests primarily in the common stock of well-know and established companies. Normally, at least 65% of the fund's total assets are invested in the common stock of blue chip companies. The fund may also invest in companies with strong earnings and future growth potential that are positioned to become blue chips of the future. Low-Priced Stock Fund - The Low-Priced Stock Fund is a growth mutual fund with the goal of capital appreciation. The fund invests primarily in stocks of companies that are considered undervalued or out of favor with other investors and could offer the possibility for significant growth. Generally, low-priced is considered $25 or less and are stocks of smaller, less well-known companies. This fund carries a redemption fee to discourage short-term buying and selling of fund shares. OTC Portfolio Fund - The OTC Portfolio Fund is a growth mutual fund. The goal of the fund is to increase the value of the investment over the long term through capital growth. The fund invests primarily in U.S. and foreign common stocks that are traded on the over-the-counter (OTC) market. The fund may also invest in bonds and other types of securities. Securities traded on the OTC market tend to be from smaller or newer companies, which generally involve greater investment risk than well-known companies. Diversified International Fund - The Diversified International Fund is a growth mutual fund that invests overseas. The goal of the fund is to increase the value of the investment over the long term through capital growth. The fund invests primarily in stocks of companies located outside the U.S. that are included in the Morgan Stanley EAFE Index. It seeks stocks that are undervalued compared to industry norms in their countries and focuses on larger companies. Emerging Markets Fund - The Emerging Markets Fund is a growth mutual fund that invests in emerging markets. The goal of the fund is to increase the value of the investment over the long term through capital growth. The fund invests primarily in stocks of companies in emerging markets. The fund emphasizes countries with relatively low GNP compared to the world's major economies, and with the potential for rapid economic growth. A redemption fee is charged if a shareholder sells shares held less than 90 days. ACNielsen Common Stock Fund - The ACNielsen Common Stock Fund invests in the common stock of ACNielsen Corporation and approved short-term instruments to provide for liquidity. Ownership is measured in units of the fund instead of shares of stock. The Plan's trustee purchases ACNielsen common stock for this fund in the open market in accordance with a nondiscretionary purchasing program. The trustee may also purchase or accept authorized but as yet unissued shares of ACNielsen common stock, or shares held as treasury shares from ACNielsen. Transaction fees related to investments in the ACNielsen Common Stock Fund are charged against the fund's assets. The charges are reflected in the total rates of return. Legacy Fund - The Legacy Fund replaced the Dun & Bradstreet Common Stock Fund in The Profit Participation Plan of The Dun & Bradstreet Corporation and was available only to former participants in that plan. At the time of the D&B reorganization, the Dun & Bradstreet Common Stock Fund became a fund consisting of shares of ACNielsen, Cognizant and D&B. Ownership was measured in units of the fund instead of shares of stock. Participants could not make additional contributions or transfers to this fund. ACNielsen exercised its right to close this fund and requested all participants in the fund to transfer their balances to one or more of the other investment options as of December 31, 1997. Transaction fees related to investments in the Legacy Fund were charged against the fund's assets. The charges were reflected in the total rates of return. All distributions from the Legacy Fund were made in cash. Asset Manager Fund - The Asset Manager Fund is an asset allocation mutual fund. The goal of the fund is to provide high total return with reduced risk over the long term. The fund invests in all basic types of investments: stocks, bonds, and short term and money market instruments.

Participants are able to reallocate their entire account balances in multiples of 1% among the funds on a daily basis subject to the 50% limit on investments in the ACNielsen Common Stock Fund. Loans Participants may obtain loans from the Plan, which are secured by the balance in their accounts. Loan transactions are recorded as transfers to/(from) the investment funds and from/(to) the loan account. Principal and interest are repaid through payroll deductions. The Plan limits the total number and amount of loans outstanding at any time for each participant. The interest rate charged on a loan for its duration is the prime rate plus two percentage points. Interest rates for participant loans ranged from 8.00% to 12.50% and terms ranged from 11 months to 119 months as of December 31, 1997. Payment of Benefits Upon termination of service with the Company, participants become eligible for a lump sum distribution of their account balance.

Retired participants may also elect payment in the form of up to 20 annual installments. Note 2. Summary of Significant Accounting Policies Basis of Accounting The financial statements of the Plan are prepared under the accrual method of accounting. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Investment Valuation and Income Recognition The Plan's investments are stated at fair value except for the insurance contracts which are stated at contract value. Contract value represents principal plus accrued interest for each contract, which approximates fair value. Investments in common stock are valued based upon quoted market prices. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Contributions Contributions by participants are recorded in the period payroll deductions are made. Distributions Distributions are recorded when paid. Risks and Uncertainties The Plan provides for various investment options in any combination of stocks, bonds, fixed income securities, registered investment companies, and other investment securities. Such investments are exposed to various risks, such as interest rate, market and credit. Due to the level of risk associated with such investments and the level of uncertainty related to changes in the value of such investments, it is at least reasonably possible that changes in risks or investment values in the near term could materially affect a participant's account balance and the amounts reported in the statement of net assets available for plan benefits with fund information and the statement of changes in net assets available for plan benefits with fund information. Plan Expenses Transaction and investment manager fees are paid by the Plan. Trustee fees and other expenses of administering the Plan may be borne by the Plan and the Company. Note 3. Related Party Transactions Certain Plan investments were shares of a short term investment fund managed by Bankers Trust. Bankers Trust was the trustee as of March 31, 1997 as defined by the Plan and, therefore, these transactions qualified as party-in-interest transactions. Note 4. Plan Termination While the Company has not expressed any intent to terminate the Plan, it is free to do so at any time subject to the provisions of ERISA and the Internal Revenue Code which state that, in such event, all participants of the Plan shall be fully vested in the amounts credited to their accounts. Note 5. Reconciliation of Financial Statements to Form 5500 As of December 31, 1997, the Plan had no pending distributions to participants who elected to withdraw from the Plan. Therefore, there were no reconciling items between the accompanying financial statements and Form 5500. Note 6. Investment Income For the year ended December 31, 1997, the Plan assets increased in value by $11,648,028 which represented interest and dividends, realized gains/losses and unrealized appreciation/depreciation for the investments. Note 7. Insurance Contracts The insurance contracts are held by John Hancock Mutual Life Insurance Company, Metropolitan Life Insurance Company, New York Life Insurance Company and Principal Mutual Life Insurance Company. There were 11 contracts with interest rates from 5.35% to 7.30% and maturities from March 1998 to October 2000 as of December 31, 1997. There are no reserves against contract value for credit risk of the contract issuer or otherwise. Note 8. Significant Investments For the year ended December 31, 1997, the Plan had the following investments which represented more than five percent of the net assets available for plan benefits: 	Fund					 		Market Value 	Growth & Income Fund			 		$33,688,107 	Managed Income Fund			 		 17,360,517 	Blue Chip Fund						 3,849,554 Note 9. Tax Status On December 18, 1997, the Company received a favorable determination letter in which the Internal Revenue Service stated that the Plan is in compliance with the requirements for a qualified plan under Section 401(a) of the Internal Revenue Code and the trust is exempt from federal income taxes under the provisions of Section 501(a) of the Code. Note 10. Change in Trustee and Creation of a Master Trust Fidelity Management Trust Company replaced Bankers Trust Company as the trustee of the Plan effective April 1, 1997. As a result of the assignment of the new trustee, a master trust was established between Fidelity Management Trust Company, the ACNielsen Corporation Savings Plan and the ACNielsen Corporation Employee Stock Ownership Plan.
