Cravath, Swaine & Moore LLP 825 Eighth Avenue New York, NY 10019 RE:	Schering Aktiengesellschaft Schedules 14D-9C March 23 and 27, 2006, April 4, 11, and 18, 2006 Schedule 14D-9 filed April 18, 2006, amended April 19, 20, and 27, 2006 File No. 005-59797 Dear Mr. Wilson: We have the following comments on the above-referenced filings. Schedule 14D-9 Joint Opinion Summary Financial Information, page 6 1. Please tell us the reason for including the "Summary Financial Information" in your Schedule 14D-9. If it is required to be presented pursuant to local law, expand the introduction to the "Summary Financial Information" to explain that it has been presented to comply with local law, that it is not required to be furnished under the SEC`s rules, and that it does not include all the disclosures that would be required under the SEC`s rules, such as a U.S. GAAP reconciliation. Also, the introduction should explain that complete information, including the U.S. GAAP reconciliation, may be located in the Registrant`s filing on Form 20-F available on the SEC`s website. 2. Please revise to include the amount of marketing and selling costs for 2005. Background of the Offer, page 8 3. Please quantify the amount of the "significant break-up fee" relating to Bayer`s potential increase of its offer to EUR 87 per share (page 10). If an amount was not determined, please state so and clarify both (i) the basis for your executive board having doubts about the "stated amount," and (ii) how the London City Code guideline would have affected such a determination. Also, clarify why your supervisory board was unable to be involved in the matter of a break-up fee at the time. 4. With respect to your disclosure in the second full paragraph of page 11 that the executive board would not seek competing offers or encourage such offers, please describe what, if any, communications were held with Merck with respect to its proposed offer. Did the executive board contact Merck seeking an increase in the consideration offered? 5. Please provide us supplementally a copy of the presentation given by Morgan Stanley to members of your boards on March 27, 2006. Persons Employed and Compensated, page 12 6. It appears that the additional fee described in clause (4) of your disclosure relating to Morgan Stanley and a similar fee for DrKW would both be payable in connection with the current transaction. Please quantify those fees. Fairness Opinion Provided by Morgan Stanley, page 15 7. With respect to the Selected Transaction Analysis, we note that you describe two calculations but presented only one in the table. Please revise to disclose the results of each calculation described. 8. Please quantify generally the fees received by Morgan Stanley and its affiliates from Bayer AG and its affiliates. Please apply this comment to the disclosure relating to the DrKW fairness opinion. Fairness Opinion Provided by Dresdner Kleinwort Wasserstein, page 23 9. We note that the compound 06-08 EPS growth results for the current transaction were lower than those resulting from the comparable companies. Please disclose how, if at all, this affected DrKW`s fairness opinion. 10. With respect to the Selected Transactions Analysis, please provide the dates of each transaction listed. Also, please add a column to the table on page 27 to show the premiums for the current transaction. 11. Please disclose with more specificity the overlaps between the boards of the transaction`s parties and DrKW`s affiliates. Valuation Opinion Provided by BDO, page 28 12. Please disclose the "appropriate discount rate" referred to in the last paragraph of page 31. Interests of the Members of the Executive Board or the Supervisory Board, page 39 13.
