instruments that potentially subject us to concentrations of credit
risk consist principally of cash and equivalents, investments, and

financial institutions and in short-duration high-quality
securities. With the exception of US Government and Agency
securities, our short-term investment policy limits the amount of
credit exposure in any one financial institution, industry group,

Deposit Insurance Corporation limits.&lt;/font&gt;&lt;/div&gt;&lt;br/&gt;&lt;div style="DISPLAY: block; MARGIN-LEFT: 0pt; TEXT-INDENT: 0pt; LINE-HEIGHT: 1.25; MARGIN-RIGHT: 0pt" align="justify"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;Our
