Loeb, an individual ("Mr. Loeb", and together with the Management Company, the "Reporting Persons"). This Amendment No. 1 relates to the common stock, par value $0.01 per share (the "Common Stock"), of IHOP Corp., a Delaware corporation (the "Company"). The Management Company is the investment manager or adviser to a variety of hedge funds and managed accounts (such funds and accounts, the "Funds"). The Funds directly own the Common Stock to which this Schedule 13D relates, and Mr. Loeb and the Management Company may be deemed to have beneficial ownership over such Common Stock by virtue of the authority granted to them by the Funds to vote and to dispose of the securities held by the Funds, including the Common Stock. Item 3. Source and Amount of Funds or Other Consideration. Item 3 of the Schedule 13D is hereby amended and restated as follows: The Funds expended an aggregate of approximately $35,143,700 of their own investment capital to acquire the 713,400 shares of Common Stock held by them. The Funds effect purchases of securities primarily through margin accounts maintained for them with Goldman, Sachs & Co., Citigroup Global Markets, Inc. and UBS Securities LLC, which may extend margin credit to the Funds as and when required to open or carry positions in the margin accounts, subject to applicable Federal margin regulations, stock exchange rules and the firm's credit policies. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the accounts. Item 5. Interest in Securities of the Issuer. Item 5 of the Schedule 13D is hereby amended and restated as follows: (a) As of August 9, 2007, the Management Company and Mr. Loeb beneficially own 713,400 shares of Common Stock (the "Shares"). The Shares represent 4.2% of the 16,910,163 shares of Common Stock outstanding as of July 27, 2007, as reported in the Company's Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2007. The percentages used herein and in the rest of this statement are calculated based upon this number of outstanding shares. (b) The Management Company and Mr. Loeb share voting and dispositive power over the 713,400 shares of Common Stock held directly by the Funds. (c) Schedule A hereto sets forth certain information with respect to transactions by the Funds (at the direction of the Management Company and Mr. Loeb) in Common Stock during the past 60 days. All of the transactions set forth on Schedule A were effected in open market transactions on the New York Stock Exchange. Other than as set forth on Schedule A, during the past 60 days there were no transactions in the Common Stock effected by the Reporting Persons nor, to the best of their knowledge, any of their directors, executive officers, general partners or members. 4 (d) Other than the Funds which directly hold the Shares, and except as set forth in this Item 5, no person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares. (e) Each of the Reporting Persons ceased to be the beneficial owner of more than five percent of the outstanding Common Stock on August 9, 2007.
