Item 3. Source and Amount of Funds or Other Consideration. n/a Item 4. Purpose of the Transaction. n/a Item 5. Interest in Securities of the Issuer. (a) As disclosed in Amendment No. 3 to the Schedule 13D, JRS Properties owned and had voting and investment power with respect to 2,722,900 Shares of Common Stock. Subsequently, JRS Properties sold Common Stock aggregating 30,000 shares, as reported in Form 4 filed February 13, 2003, and JRS Properties transferred by gift 52,000 shares to the Foundation, as reported in Form 4 filed December 29, 2003. On September 1, 2004, JRS Properties transferred by gift to the Foundation 833,333 shares of Common Stock. Subsequent to these sales and gifts, JRS Properties owned voting and investment power with respect to 1,807,567 shares of Common Stock, including 950,000 shares subject to certain previously-reported variable share forward sale contracts. Page 8 of 10 On September 1, 2004, after the gift reported in this Item 5(a), JRS Properties merged into JRS Properties III, with JRS Properties III remaining as the surviving entity (the "Merger"). As a result of the Merger, all 1,807,567 shares of Common Stock owned by JRS Properties became owned by JRS Properties III. Adding these shares to the 2,785,028 shares already owned by JRS Properties III results in JRS Properties III owning 4,592,595 shares of Common Stock. Concurrently with the Merger, the surviving general partner of the two limited partnerships was JRS Management. JRS Management is now the general partner of JRS Properties III. On September 1, 2004, JRS Management filed an amendment to its articles of organization with the Idaho Secretary of State pursuant to which the managers described above in Item 2 became the managers. As a result of these transactions: (1) JRS Properties III beneficially owns and has voting and investment power with respect to 4,592,595 shares of Common Stock, representing 16.7% of the outstanding Common Stock. (2) Mr. Simplot shares with Mrs. Simplot voting and investment power with respect to 1000 shares of Common Stock, representing .0036% of the outstanding Common Stock. (3) Mr. Simplot shares with the other directors of the Foundation voting and investment power with respect to the 885,333 shares of Common Stock held by the Foundation, representing 3.2% of the outstanding Common Stock.
