NOTE 9    INTANGIBLE ASSETS

The components of finite-lived intangible assets are as follows:

(In millions)
June 30	2004						2005
	Gross carrying amount		Accumulated amortization		Net carrying amount		Gross carrying amount		Accumulated amortization		Net carrying amount
Contract-based	$0,908		$(476)		$432		$0,957		$(606)		$351
Technology-based	278		(183)		95		309		(200)		109
Marketing-related	35		(19)		16		35		(25)		10
Customer-related	30		(4)		26		40		(11)		29
Total	$1,251		$(682)		$569		$1,341		$(842)		$499

During fiscal year 2004, we recorded additions to intangible assets of $355 million, of which $266 million was related to a comprehensive intellectual property license that we received in conjunction with the settlement of InterTrust v. Microsoft. During fiscal year 2005, we recorded additions to finite-lived intangible assets of approximately $90 million. No other material intangibles were acquired in fiscal year 2004. We estimate that we have no significant residual value related to our finite-lived intangible assets. The components of finite-lived intangible assets acquired during fiscal years 2004 and 2005 are as follows:

(In millions)
Year Ended June 30	2004				2005
	Amount		Weighted average life		Amount		Weighted average life
Contract-based	$324		9 years		$16		6 years
Technology-based	28		4 years		64		5 years
Customer-related	3		3 years		10		5 years
Marketing-related	–		–		–		–
Total	$355				$90

Acquired finite-lived intangibles are generally amortized on a straight-line basis over weighted average periods. Intangible assets amortization expense was $170 million for fiscal year 2004 and $161 million for fiscal year 2005. The estimated future amortization expense related to intangible assets as of June 30, 2005 is as follows:

(In millions)
Year Ended June 30	Amount
2006	$123
2007	99
2008	81
2009	50
2010	39
Total	$392
