Our report dated July 31, 2006, on management’s assessment of the effectiveness of internal control over financial reporting and the effectiveness of internal control over financial reporting as of March 31, 2006, expresses our opinion that CA, Inc. did not maintain effective internal control over financial reporting as of March 31, 2006 because of the effect of material weaknesses on the achievement of the objectives of the control criteria and contains an explanatory paragraph that states: (i) the Company did not maintain an effective control environment due to a lack of effective communication policies and procedures; (ii) the Company’s policies and procedures relating to controls over the accounting for sales commissions were not effective; (iii) the Company’s policies and procedures relating to the identification, analysis and documentation of non-routine tax matters were not effective; (iv) the Company’s policies and procedures relating to the accounting for and disclosure of stock-based compensation relating to stock options were not effective; and (v) the Company’s policies and procedures were not effectively designed to identify, quantify and record the impact on subscription revenue when license agreements have been cancelled and renewed more than once prior to the expiration date of each successive license agreement.

As discussed in Note 12, the consolidated financial statements as of March 31, 2005 and for each of the years in the two-year period ended March 31, 2005 have been restated.
