For the nine months ended April 26, 2014, the realized net gains related to the Company's available-for-sale investments included impairment charges of $11 million. These impairment charges related to publicly traded equity securities and were due to a decline in the fair value of those securities below their cost basis that were determined to be other than temporary. There were no impairment charges on available-for-sale investments for the corresponding periods in fiscal 2013.

As of April 26, 2014, for fixed income securities that were in unrealized loss positions, the Company has determined that (i) it does not have the intent to sell any of these investments, and (ii) it is not more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis. In addition, as of April 26, 2014, the Company anticipates that it will recover the entire amortized cost basis of such fixed income securities and has determined that no other-than-temporary impairments associated with credit losses were required to be recognized during the nine months ended April 26, 2014.

The Company has evaluated its publicly traded equity securities as of April 26, 2014 and has determined that there was no indication of other-than-temporary impairments in the respective categories of unrealized losses. This determination was based on several factors, which include the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the issuer, and the Company’s intent and ability to hold the publicly traded equity securities for a period of time sufficient to allow for any anticipated recovery in market value.


(c)	Maturities of Fixed Income Securities

The following table summarizes the maturities of the Company’s fixed income securities at April 26, 2014 (in millions):



	Amortized Cost		Fair Value
Less than 1 year	$	15,022	$	15,038
Due in 1 to 2 years	13,061		13,101
Due in 2 to 5 years	13,380		13,415
Due after 5 years	708		715
Total	$	42,171	$	42,269

Actual maturities may differ from the contractual maturities because borrowers may have the right to call or prepay certain obligations.


(d)	Securities Lending

The Company periodically engages in securities lending activities with certain of its available-for-sale investments. These transactions are accounted for as a secured lending of the securities, and the securities are typically loaned only on an overnight basis. The average daily balance of securities lending for the nine months ended April 26, 2014 and April 27, 2013 was $1.4 billion and $0.7 billion, respectively. The Company requires collateral equal to at least 102% of the fair market value of the loaned security and that the collateral be in the form of cash or liquid, high-quality assets. The Company engages in these secured lending transactions only with highly creditworthy counterparties, and the associated portfolio custodian has agreed to indemnify the Company against collateral losses. The Company did not experience any losses in connection with the secured lending of securities during the periods presented. As of April 26, 2014 and July 27, 2013, the Company had no outstanding securities lending transactions.
