Filed by Ameritrade Holding Corporation
Pursuant to Rule 14a-6(b) under the
Securities Exchange Act of 1934
Subject Company: Ameritrade Holding Corporation
Commission File No.: 000-49992

On December 23, 2005, Ameritrade Holding Corporation, a Delaware corporation (“Ameritrade”), entered into Amendment No. 2 to the Agreement of Sale and Purchase (the “Amendment”) with The Toronto-Dominion Bank (“TD”). The Amendment amends the Agreement of Sale and Purchase (the “Purchase Agreement”) between Ameritrade and TD, dated June 22, 2005, as amended on October 28, 2005, pursuant to which, among other things, Ameritrade agreed to purchase from TD (the “Share Purchase”) all of the capital stock of TD Waterhouse Group, Inc., a Delaware corporation and wholly owned subsidiary of TD (“TD Waterhouse”), in exchange for 196,300,000 shares of common stock, par value $0.01 per share, of Ameritrade (the “Stock Consideration”) and $20,000 in cash.

Pursuant to the Amendment, the TD Waterhouse Canadian Call Center Inc. (“Canadian Call Center”) will be a “Business Subsidiary” under the Purchase Agreement and will therefore be purchased by Ameritrade as part of its acquisition of TD Waterhouse. Canadian Call Center is a branch office of TD Waterhouse Investor Services, Inc. Ameritrade has entered into a services agreement with TD and TD Waterhouse Investor Services, Inc. under which Canadian Call Center will be provided call center services from Canada by TD. Canadian Call Center has no significant assets or liabilities, other than those pursuant to the services agreement and its registration as a branch office of a New York Stock Exchange member firm.

A copy of Amendment No. 2 is filed as Exhibit 2.3 to Ameritrade’s Current Form 8-K filed December 29, 2005.
