INTRODUCTION

This  Amendment No. 4 (the “Amendment”) amends and supplements the Tender Offer Statement on Schedule TO originally filed with the Securities and Exchange Commission on November 7, 2006, as amended on November 16, 2006 by Amendment No. 1 to the Tender Offer Statement on Schedule TO, on December 5, 2006 by Amendment No. 2 to the Tender Offer Statement on Schedule TO and on December 8, 2006 by Amendment No. 3 to the Tender Offer Statement on Schedule TO (collectively, the “Schedule TO”), which relates to the offer by CA, Inc., a Delaware corporation (the “Company”), to cancel certain stock options previously granted to its employees under its 1991 Stock Incentive Plan, as amended and restated (the “1991 Plan”) with a grant date of July 20, 2000 in exchange for new options (the “New Options”).  The options granted on July 20, 2000 entitle the option holders to purchase shares of the Company’s common stock at  an exercise price per share of  $27.00. The Company recently determined that the fair market value of the Company’s common stock on the measurement date for those options for accounting and tax purposes was $37.50 per share, or $10.50 higher than the $27.00 per share exercise price. CA is making this offer because of potential adverse tax consequences to the option holders that apply when the exercise price of stock options is lower than the market price of a company’s stock on the measurement date for tax purposes. The offer is subject to the terms and conditions set forth in the Offer to Exchange dated November 7, 2006 (the “Offer”) and the related Letter of Transmittal , previously filed as Exhibits (a)(1) and (a)(3), respectively, to the Schedule TO. This Amendment is intended to satisfy the reporting requirements of Rule 13e-4(c)(2) of the Securities Exchange Act of 1934.

The information set forth in the Offer, including all schedules and annexes thereto, which were previously filed with the Schedule TO, is hereby expressly incorporated by reference into this Amendment, except that such information is hereby amended and supplemented to the extent specifically provided herein and all references herein to sections and page numbers in the Offer refer to sections and page numbers in the Offer as it was filed with the SEC via EDGAR with the Schedule TO.

This Amendment No. 4 is made to report the results of the Exchange Offer.

Item 4. Terms of the Transaction.

Item 4 of the Schedule TO is hereby amended to add the following sentences: The tender offer expired at 5:00 p.m., Eastern Time, on December 7, 2006. Pursuant to the Offer, we have accepted for cancellation options to purchase 867,160 shares of the Company’s common stock and will grant new options to purchase 867,160 shares of the Company’s common stock.

This Amendment No. 4 to the Schedule TO is filed in satisfaction of the reporting requirements of Rule 13e-4(c)(3) promulgated under the Securities Exchange Act of 1934, as amended.
