EX-99.1: RECONCILIATION OF NON-GAAP MEASURES
Published on May 7, 2007
    Exhibit 99.1
    Merrill
    Lynch & Co., Inc.
    Reconciliation
    of Non-GAAP Measures
    Merrill Lynch adopted Statement of Financial Accounting
    Standards No. 123 (as revised in 2004) for stock-based
    employee compensation during the first quarter 2006.
    Additionally, as a result of a comprehensive review of the
    retirement provisions in its stock-based compensation plans,
    Merrill Lynch also modified the retirement eligibility
    requirements of existing stock awards in order to facilitate
    transition to more stringent retirement eligibility requirements
    for future stock awards. These modifications and the adoption of
    the new accounting standard required Merrill Lynch to accelerate
    the recognition of compensation expenses for affected stock
    awards, resulting in the one-time compensation
    expenses. These changes represent timing differences and
    are not economic in substance. Management believes that while
    the results excluding the one-time expenses are considered
    non-GAAP measures, they depict the operating performance of the
    company more clearly and enable more appropriate
    period-to-period
    comparisons.
