fiscal 2010, we sold our remaining portfolio of ARS and held no
investment securities at September 30, 2010. At September 30, 2009,
our portfolio of investment securities was comprised entirely of
$21.6 million (par) of ARS.&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="left"&gt;&lt;font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;ARS
are fixed rate debt securities with underlying long-term
maturities, designed to reset to market rates when traded through a
modified Dutch auction process at predetermined short-term
intervals, typically 7, 28, or 35 days. These debt securities
actively traded at par previous to auction failures which began in
February 2008.&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;In
November 2008, we accepted ARS put rights offered by our broker,
UBS Securities LLC, entitling us to sell our ARS through
appropriate UBS entities at par plus accrued interest during the
exercise period from June 30, 2010 through July 2, 2012. The put
rights were a separate freestanding instrument accounted for
separately from the ARS. Upon acceptance of the put rights, we
reclassified our ARS from &amp;#8220;available-for-sale&amp;#8221; to
&amp;#8220;trading&amp;#8221; and elected to carry the put at fair value.
This election reflected the appropriate economic relationship
between the put and the underlying ARS as changes in the respective
fair values largely offset.&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;We
recorded the following changes in fair value related to our ARS and
the related put rights:&lt;/font&gt;&lt;/div&gt;&lt;br/&gt;&lt;table align="center" border="0" cellpadding="0" cellspacing="0" id="hangingindent-11" width="100%" style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; FONT-SIZE: 10pt; FONT-FAMILY: times new roman"&gt;
