Acquisition or Disposition of Assets. On August 19, 2003, Merck & Co., Inc. ("Merck") completed the spin-off of Medco Health Solutions, Inc. ("Medco Health"), its wholly owned pharmacy benefit management subsidiary. The spin-off was effected by way of a pro rata dividend to Merck stockholders. Holders of Merck common stock at the close of business on August 12, 2003, received a dividend of .1206 shares of Medco Health common stock for every one share of Merck common stock held on that date. No fractional shares of Medco Health common stock were issued. Shareholders entitled to a fractional share of Medco Health common stock in the distribution received the cash value instead. Based on a letter ruling Merck received from the U.S. Internal Revenue Service, receipt of Medco Health shares in the distribution will be tax-free for U.S. federal income tax purposes, but any cash received in lieu of fractional shares will be taxable.
