Market values were determined for each individual security in
the investment portfolio. The declines in value of these
investments are primarily related to changes in interest rates
and are considered to be temporary in nature. It is not more
likely than not that we will be required to sell these
securities before the recovery of their amortized cost
basis; therefore we do not consider these investments to be

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.Reference 1: http://www.xbrl.org/2003/role/presentationRef
