CA ANNOUNCES SATISFACTION OF FINANCING CONDITION
UNDER ITS $1 BILLION TENDER OFFER

ISLANDIA, N.Y., Sept. 6, 2006—CA (NYSE: CA), one of the world’s largest management software companies, announced today that it has entered into an amendment to its existing credit facility that satisfies the financing condition under its previously announced $1 billion tender offer. The amendment modifies certain covenants in the credit agreement in order to permit CA to repurchase up to $2 billion of its common stock under its fiscal year 2007 share repurchase program and incur additional indebtedness in connection with those repurchases.

CA expects to use the borrowings under the revolving credit facility to complete a portion of the $1 billion tender offer launched August 16, 2006, and to pay related fees and expenses. CA has stated that it plans to use a combination of available cash and bank borrowings to finance the tender offer. The successful completion of debt financing on terms and conditions satisfactory to CA in an amount sufficient to purchase shares offered in the tender offer was a condition to the completion of the tender offer. This condition has now been satisfied by CA.

The $1 billion tender offer is the first phase of the $2 billion stock repurchase program announced June 29, 2006 by the Company. CA is considering various options to execute the second phase of the program and will provide further details when appropriate. The Company expects to complete the full $2 billion share repurchase plan by the end of its 2007 fiscal year.

The Company has filed a Form 8-K with the Securities Exchange Commission (SEC) in connection with the amendment of the credit agreement.
