available-for-sale securities are included in other income or expense. The decline in fair value of
certain of our investments is judged by us, on an individual basis, to be temporary. We do not
intend to sell an impaired security, and it is not more likely than not that we will be required to
sell the security before the recovery of its amortized cost basis. See Footnote 4 – Fair Value
Measurements for further discussion.

This item represents the entire disclosure related to Available-for-sale Securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities which are categorized as Available-for-sale.
