         On August 4, 2004 Fresenius Medical Care AG (the "Company") issued a
press release announcing its second quarter 2004 earnings results. A copy of the
press release is furnished as Exhibit 99.1.

         The attached press release contains non-GAAP financial measures. For
purposes of Regulation G, a non-GAAP financial measure is a numerical measure of
a company's performance, financial position, or cash flows that either excludes
or includes amounts that are not normally excluded or included in the most
directly comparable measure calculated and presented in accordance with
generally accepted accounting principles. To supplement our second quarter 2004
consolidated financial results presented in accordance with Generally Accepted
Accounting Principles in the United States, or GAAP, we have used non-GAAP
financial measure of (a) operating income excluding depreciation, amortization,
and minority interests, (b) free cash flow, and (c) dialysis product sales to
the available external market. These non-GAAP measures are provided to enhance
the user's overall understanding of our current financial performance and our
prospects for the future. In addition, because we have historically reported
certain non-GAAP financial measures in our financial results, we believe the
inclusion of these non-GAAP financial measures provides consistency and
comparability in our financial reporting to prior periods for which these
non-GAAP financial measures were previously reported. These non-GAAP financial
measures should not be used as a substitute for or be considered superior to
GAAP financial measures. Reconciliation of the non-GAAP financial measures to
the most comparable GAAP financial measures are included in the attached press
release.

         The Exhibit attached hereto, shall not be deemed "filed" for purposes
of Section 18 of the Securities and Exchange Act of 1934 (the "Exchange Act") or
otherwise subject to the liabilities of that section, nor shall it be deemed
incorporated by reference in any filing under the Securities Act of 1933 or the
Exchange Act, regardless of any general incorporation language in such filing.
