Investments, Debt and Equity Securities [Abstract]

5. Investment Securities

Investment securities principally include debt securities the Company classifies as available-for-sale and carries at fair value on the Consolidated Balance Sheets, with unrealized gains (losses) recorded in Accumulated Other Comprehensive Loss, net of income taxes. Realized gains and losses are recognized on a trade-date basis in results of operations upon disposition of the securities using the specific identification method.

The following is a summary of investment securities as of June 30, 2015 and December 31, 2014:

The gross unrealized losses are attributed to overall wider credit spreads for state and municipal securities, wider credit spreads for specific issuers, adverse changes in market benchmark interest rates, or a combination thereof, all as compared to those prevailing when the investment securities were acquired.

Overall, for the investment securities in gross unrealized loss positions (i) the Company does not intend to sell the investment securities, (ii) it is more likely than not that the Company will not be required to sell the investment securities before recovery of the unrealized losses, and (iii) the Company expects that the contractual principal and interest will be received on the investment securities. As a result, the Company recognized no other-than-temporary impairment during the periods presented.

Contractual maturities of investment securities with stated maturities as of June 30, 2015 were as follows:

				Estimated
(Millions)		Cost		Fair Value
Due within 1 year	$	1,004	$	1,005
Due after 1 year but within 5 years		329		336
Due after 5 years but within 10 years		225		239
Due after 10 years		2,857		2,955
Total^(a)	$	4,415	$	4,535

Balances primarily represent investments in state and municipal obligations, and foreign government bonds and obligations.

The expected payments on state and municipal obligations and mortgage-backed securities may not coincide with their contractual maturities because the issuers have the right to call or prepay certain obligations.
