- ------------------------

(a) 2001 includes $22.5 million on pretax charges for write-downs, reserves and
    recoveries and $26.2 million of income from dispositions of nonstrategic
    assets and the settlement of a contingency related to a former affiliate.
    2001 also includes the financial results of Harveys Casino Resorts from its
    July 31, 2001, date of acquisition.

(b) 2000 includes $220.0 million in pretax reserves for receivables not expected
    to be recovered from JCC Holding Company and its subsidiary, Jazz Casino
    Company, LLC, $6.1 million in pretax charges for other write-downs, reserves
    and recoveries and $39.4 million in pretax write-offs and reserves for our
    investment in, loans to and net estimated exposure under letters of credit
    issued on behalf of National Airlines, Inc. 2000 also includes the financial
    results of Players International, Inc. from its March 22, 2000, date of
    acquisition.

(c) 1999 includes $2.2 million in pretax charges for write-downs, reserves and
    recoveries and $59.8 million of gains from sales of our equity interests in
    nonconsolidated affiliates. 1999 also includes the financial results of Rio
    Hotel & Casino, Inc. from its January 1, 1999, date of acquisition.

(d) 1998 includes $7.5 million in pretax charges for write-downs and reserves
    and a $13.2 million gain on the sale of equity interests in a
    nonconsolidated restaurant subsidiary. 1998 also includes the financial
    results of Showboat, Inc. from its June 1, 1998, date of acquisition.

(e) 1997 includes $13.8 million in pretax charges for write-downs and reserves
    and a $37.4 million gain on the sale of equity in a New Zealand subsidiary.

(f) Revenues for years 1997 through 2000 have been restated to reflect the
    impact of implementing new accounting guidance issued in and effective for
    first quarter 2001, which requires the cost of the cash-back component of
    the Company's Total Rewards program to be treated as a reduction of
    revenues. Previously, these costs had been treated as a casino expense.

(g) As discussed in Note 12 to the Consolidated Financial Statements in the 2001
    Harrah's Entertainment Annual Report, the Company has guaranteed certain
    third-party loans in connection with its casino development activities. The
    above ratio computation excludes estimated

                                       2

                                                          EXHIBIT 12 (CONTINUED)
    fixed charges associated with these guarantees as follows: 2001,
    $4.4 million; 2000, $5.7 million; 1999, $6.2 million; 1998, $7.9 million;
    and 1997, $7.8 million.

(h) For purposes of computing this ratio, "earnings" consist of income before
    income taxes plus fixed charges (excluding capitalized interest) and
    minority interests (relating to subsidiaries whose fixed charges are
    included in the computation), excluding equity in undistributed earnings of
    less than 50% owned investments. "Fixed charges" include interest whether
    expensed or capitalized, amortization of debt expense, discount or premium
    related to indebtedness and such portion of rental expense that we deem to
    be representative of interest. As required by the rules which govern the
    computation of this ratio, both earnings and fixed charges are adjusted
    where appropriate to include the financial results for the company's
    nonconsolidated majority-owned subsidiaries. Accordingly, 1998 has been
    adjusted to include the financial results and fixed charges of the East
    Chicago partnership from its June 1, 1998, date of acquisition.

(i) EBITDA consists of earnings before interest, taxes, depreciation and
    amortization. Property EBITDA consists of operating profit before
    depreciation and amortization, write-downs, reserves and recoveries and
    project opening costs. Property EBITDA is a supplemental financial measure
    used by management, as well as industry analysts, to evaluate our
    operations. However, property EBITDA should not be construed as an
    alternative to Income from operations (as an indicator of our operating
    performance) or to cash flows from operating activities (as a measure of
    liquidity) as determined in accordance with generally accepted accounting
    principles and presented in the accompanying Consolidated Financial
    Statements. All companies do not calculate EBITDA in the same manner. As a
    result, property EBITDA as presented by our Company may not be comparable to
    similarly titled measures presented by other companies.
