3 This Amendment No. 24 amends the Schedule 13D Statement originally filed by Interstate Properties ("Interstate") on September 26, 1980 with respect to the Common Stock, par value $1.00 per share (the "Shares") of Alexander's, Inc., a Delaware corporation (the "Company"). Item 5. Interest in Securities of the Issuer. (a) - (b) Interstate owns 1,354,568 Shares (27.1% of the 5,000,850 Shares reported by the Company as outstanding as of November 4, 1994 in its Quarterly Report on Form 10-Q for the three months ended September 30, 1994). Interstate has sole voting and dispositive power with respect to such Shares. While Interstate may be deemed to be a group with Vornado Realty Trust, a Maryland real estate investment ("Vornado") which Interstate owns 31% of, and thus to beneficially own all shares held by Vornado (1,466,568 Shares or 29.3%), Interstate does not have sole or shared voting or dispositive power with respect to such Shares. Including the Shares Vornado beneficially owns, Interstate would own 2,821,136 Shares (56.4%). In addition, Mr. Roth, a general partner of Interstate, owns 9,700 shares, as to which he has sole voting and dispositive power. (c) Other than the purchase by Vornado of 1,353,468 Shares from Citibank, N.A. on March 2, 1995 pursuant to the Stock Purchase Agreement dated February 6, 1995, there have been no transactions in the Shares effected by Vornado or Interstate or any of the general partners of Interstate in the past sixty days.
