This Amendment No. 6 to Schedule 13D relates to the Class A Common Stock, $1.00 par value per share (the “Common Stock”), of Schnitzer Steel Industries, Inc. (the “Issuer”) and is being filed on behalf of the undersigned to amend the Schedule 13D that was originally filed on January 5, 1998 and previously amended by Amendment No. 1 filed with the SEC on September 18, 1998, by Amendment No. 2, filed with the SEC on October 15, 1998, by Amendment No. 3, filed with the SEC on May 30, 2003, by Amendment No. 4, filed with the SEC on August 5, 2003, and by Amendment No. 5, filed with the SEC on September 26, 2003.
Item 5.	Interest in Securities of the Issuer
(a)-(b) The calculations included herein are based on a total of 13,304,516 shares of Common Stock, which is the number of shares outstanding as of November 1, 2003, as last reported by the Issuer in its Form 10-K for the fiscal year ended August 31, 2003, filed with the SEC on November 24, 2003 (the “2003 10-K”). As of the close of business on December 11, 2003, Cascade owns 452,400 shares of Common Stock, constituting approximately 3.4% of the issued and outstanding shares of Common Stock. All shares of Common Stock beneficially owned by Cascade may be deemed to be beneficially owned by William H. Gates III as the sole member of Cascade and Mr. Gates has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, such shares.
(c) Between October 3, 2003 and November 24, 2003, Cascade sold a total of 92,000 shares of Common Stock on the dates and at the prices set forth on Exhibit 2 for cash in open market transactions. Since November 24, 2003, the date on which Cascade and Mr. Gates determined that they were no longer the beneficial owners of more than five percent of the Common Stock, Cascade sold a total of 150,000 shares of Common Stock, which includes 25,000 shares sold on November 25 at an average price of $51.77, 25,000 shares sold on December 1 at an average price of $48.23 and 100,000 shares sold on December 2 at an average price of $48.61. The sales were made for cash in open market transactions.
(d) Not applicable.
(e) Cascade and Mr. Gates determined on November 24, 2003, that they were no longer the beneficial owners of more than five percent of the Common Stock, as a result of a significant increase in the number of shares of Common Stock outstanding, as reported in the 2003 10-K filed on that date.
