(a) Unusual charges in 1993 totaling $229.8 million before taxes in connection
    with the purchase of 50% interest in the Macmillan/McGraw-Hill School
    Publishing Company owned by Macmillan for $337.5 million in cash. The
    unusual charges conisted of $199.8 million primarily to adjust the
    company's original investment to values established in this transaction.
    This charge has been allocated primarily to goodwill and other intangibles.
    In addition, the company recorded a provision of $30 million relating to
    the consolidation of certain functions and systems of Macmillan/McGraw-Hill
    and the company's book publishing operations.

    Unusual charges in 1989 total $220 million before taxes.  They include the
    write-down of goodwill and other intangible assets of certain acquired
    units of $82 million, a provision for the shutdown of certain units and the
    write- down of other non-performing units and assets of $63 million and a
    reserve of $75 million for severance payments associated with staff
    reductions and for other items.

(b) For purposes of computing the ratio of earnings to fixed charges, "earnings
    from continuing operations before income taxes" excludes undistributed
    equity in income of less than 50%-owned companies.  "Fixed charges" consist
    of (1) interest on debt and capital leases, (2) the portion of the
    company's rental expense deemed representative of the interest factor in
    rental expense, and (3) the company's proportionate share of such fixed
    charges of the Macmillan/McGraw-Hill joint venture through September 30,
    1993.

(c) The cumulative adjustment in 1992 reflects the adoption of FAS 106,
    "Employers' Accounting for Postretirement Benefits Other Than Pensions",
    $183.5 million pretax, and FAS 112, "Employers' Accounting for
    Postemployment Benefits", $25.3 million pretax.
