Available For Sale Investments [Text Block]

7.      Available-for-Sale Investments

The following is a summary of the fair value of available-for-sale investments (in millions):

	Amortized cost				Fair value
	June 30, 2014		December 31, 2013		June 30, 2014		December 31, 2013
Bonds, notes and other securities:
U.S. government and agencies	$	758	$	530	$	759	$	531
Equity securities	$	6			$	9
Total short-term investments	$	764	$	530	$	768	$	531
Asset-backed securities	$	44	$	46	$	39	$	38
Total long-term investments	$	44	$	46	$	39	$	38

We do not intend to sell, nor do we believe it is more likely than not that we would be required to sell, the long-term investment asset-backed securities (which are collateralized by mortgages) before recovery of their amortized cost basis.  It is possible that a significant degradation in the delinquency or foreclosure rates in the underlying assets could cause further temporary or other-than-temporary impairments in the future.

The following table summarizes the contractual maturities of available-for-sale securities at June 30, 2014 (in millions):

Less than one year	$524
Due in 1-5 years	235
Due in 5-10 years	0
Due after 10 years (1)	39
Total	$798

(1) Includes $39 million of asset-based securities that mature over time and are being reported at their final maturity dates.

Unrealized gains and losses, net of tax, are computed on a specific identification basis and are reported as a separate component of accumulated other comprehensive income in shareholders’ equity until realized.

The following tables provide the fair value and gross unrealized losses of the Company’s investments aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at June 30, 2014 and December 31, 2013 (dollars in millions):

		June 30, 2014
		12 months or greater				Total
	Number of securities in a loss position	Fair value		Unrealized losses (1)		Fair value		Unrealized losses
Asset-backed securities	21	$	39	$	(5)	$	39	$	(5)
Total long-term investments	21	$	39	$	(5)	$	39	$	(5)

(1) Unrealized losses in securities less than 12 months were not significant.

		December 31, 2013
		12 months or greater				Total
	Number of securities in a loss position	Fair value		Unrealized losses (1)		Fair value		Unrealized losses
Asset-backed securities	20	$	38	$	(8)	$	38	$	(8)
Total long-term investments	20	$	38	$	(8)	$	38	$	(8)

(1) Unrealized losses in securities less than 12 months were not significant.

As of June 30, 2014 and December 31, 2013, for securities that have credit losses, an unrealized loss on other than temporary impaired securities of $4 million and $6 million, respectively, is recognized in accumulated other comprehensive income.

Proceeds from sales and maturities of short-term investments totaled approximately $0.6 billion and $1.0 billion for the six months ended June 30, 2014 and 2013, respectively.
