The annual validation test for all reporting units was performed during the second quarter ended October 1, 2004, which supported the goodwill balance.

Additions to U.S. Federal goodwill during the six months ended October 1, 2004 relate to the purchase of a minority share in a joint venture. The foreign currency translation amount relates to the impact of foreign currency adjustments in accordance with SFAS No. 52, "Foreign Currency Translation."

Note 9 - Goodwill and Other Intangible Assets (continued)

A summary of amortizable intangible assets as of October 1, 2004 and April 2, 2004 is as follows:

Amortization expense related to intangible assets was $98.8 million and $85.7 million for the three months and $192.2 million and $169.6 for the six months ended October 1, 2004 and October 3, 2003, respectively. Estimated amortization expense related to intangible assets as of April 2, 2004 for each of the subsequent five fiscal years, fiscal 2005 through fiscal 2009, is as follows (in millions): $347, $301, $263, $202, and $167.

Note 10 - Special Items

No charges were recorded during the quarter and six months ended October 1, 2004. As disclosed in the Company's fiscal 2004 Annual Report on Form 10-K, the Company completed its review of operations, product strategies and the carrying value of its assets to identify any potential exit or disposal activities in connection with the DynCorp acquisition during March 2003. During the second quarter and six months ended October 3, 2003, special items of $9.2 million and $15.4 million ($5.7 million and $9.6 million after tax) or 3 cents and 5 cents per share (diluted) were recorded, respectively. The charges include equipment and related disposal costs, that cannot accommodate the larger, integrated U.S. Federal sector business, and its use has been discontinued.

Note 11 - Acquisitions

As a result of the DynCorp acquisition, the Company incurred costs to exit and consolidate activities, involuntarily terminate employees, and other costs to integrate DynCorp into the Company. Generally accepted accounting principles require that these costs, which are not associated with the generation of future revenues and have no future economic benefit, be reflected as assumed liabilities in the allocation of the purchase price to the net assets acquired, and such costs appear below. As of October 1, 2004, all 63 employees identified for employment termination had been involuntarily terminated. The facility consolidations relate to plans to vacate and sublease DynCorp facilities. The costs include amounts estimated by a third party as not recoverable under sublease. The components of the final acquisition integration liabilities included in the purchase price allocation for DynCorp are presented in the following table.

Note 12 - Commitments and Contingencies

The Company guarantees working capital credit lines established with local financial institutions for its foreign business units. Generally, guarantees have one-year terms and are renewed annually. CSC guarantees up to $473.6 million of such working capital lines; however, as of October 1, 2004, the amount of the maximum potential payment is $55.5 million, the amount of the related outstanding subsidiary debt. The $55.5 million outstanding debt is reflected in the Company's consolidated financial statements.

On August 13, 2004, the Company entered into a $700 million long term credit agreement that replaced its existing short term and long term credit facilities and will expire on August 13, 2009. At the time the new credit agreement was signed, neither the short term nor the long term credit facility had an outstanding balance. On October 1, 2004 the new long term credit facility had $700 million of unutilized capacity.

The Company indemnifies its software license customers from claims of infringement on a United States patent, copyright, or trade secret. CSC's indemnification covers costs to defend customers from claims, court awards or related settlements. The Company maintains the right to modify or replace software in order to eliminate any infringement. Historically, CSC has not incurred any significant costs related to customer software license indemnification. Management considers the likelihood of incurring future costs to be remote. Accordingly, the Company has not recorded a related liability.

The Company is currently party to a number of disputes which involve or may involve litigation. The Company consults with legal counsel on those issues related to litigation and seeks input from other experts and advisors with respect to matters in the ordinary course of business. It is the opinion

Note 12 - Commitments and Contingencies (continued)

of Company management that ultimate liability, if any, with respect to these disputes will not be material to the Company's consolidated financial statements.

Note 13 - Pension and Other Benefit Plans

The Company and its subsidiaries offer a number of pension and postretirement healthcare and life insurance benefit plans. The components of net periodic benefit cost for defined benefit pension and postretirement benefit plans are as follows (in millions):
