(a)
Investments with no stated maturities are included as contractual maturities of greater than 10 years. Actual maturities may differ due to call or prepayment options.
(b)
Yields on tax-exempt obligations are computed on a tax-equivalent basis.
The balances of cash equivalents were $2.7 billion and $3.4 billion at March 31, 2013, and December 31, 2012, respectively, and were composed primarily of money market accounts and short-term securities, including U.S. Treasury bills.

Certain available-for-sale securities were sold at a loss in 2013 as a result of market conditions within these respective periods. The table below summarizes available-for-sale securities in an unrealized loss position in accumulated other comprehensive income. Based on the methodology described below that was applied to these securities, we believe that the unrealized losses relate to factors other than credit losses in the current market environment. As of March 31, 2013, we did not have the intent to sell the debt securities with an unrealized loss position in accumulated other comprehensive income, and it is not more likely than not that we will be required to sell these securities before recovery of their amortized cost basis. As of March 31, 2013, we had the ability and intent to hold equity securities with an unrealized loss position in accumulated other comprehensive income. As a result, we believe that the securities with an unrealized loss position in accumulated other comprehensive income are not considered to be other-than-temporarily impaired at March 31, 2013. Refer to Note 1 to the Consolidated Financial Statements in our 2012 Annual Report on Form 10-K for additional information related to investment securities and our methodology for evaluating potential other-than-temporary impairments.
