Cash Equivalents, and Marketable Securities</b></font></p>
<p style="MARGIN-TOP: 6px; MARGIN-BOTTOM: 0px; TEXT-INDENT: 40px">
<font style="FONT-FAMILY: Times New Roman" size="2">As of
March 31, 2010, and December 31, 2009, our cash, cash
equivalents, and marketable securities primarily consisted of cash,
government and government agency securities, AAA-rated money market
funds, and other investment grade securities. Our marketable
fixed-income securities have maturities of less than 5 years. Cash
equivalents and marketable securities are recorded at fair value.
Fair value is defined as the price that would be received to sell
an asset or paid to transfer a liability in an orderly transaction
between market participants at the measurement date. To increase
the comparability of fair value measures, the following hierarchy
prioritizes the inputs to valuation methodologies used to measure
fair value:</font></p>
<p style="MARGIN-TOP: 6px; MARGIN-BOTTOM: 0px; MARGIN-LEFT: 40px">
<font style="FONT-FAMILY: Times New Roman" size="2"><b>Level 1</b>—Valuations based on quoted prices for
identical assets and liabilities in active markets.</font></p>
<p style="MARGIN-TOP: 6px; MARGIN-BOTTOM: 0px; MARGIN-LEFT: 40px">
<font style="FONT-FAMILY: Times New Roman" size="2"><b>Level 2</b>—Valuations based on observable inputs
other than quoted prices included in Level 1, such as quoted prices
for similar assets and liabilities in active markets, quoted prices
for identical or similar assets and liabilities in markets that are
not active, or other inputs that are observable or can be
corroborated by observable market data.</font></p>
<p style="MARGIN-TOP: 6px; MARGIN-BOTTOM: 0px; MARGIN-LEFT: 40px">
<font style="FONT-FAMILY: Times New Roman" size="2"><b>Level 3</b>—Valuations based on unobservable
inputs reflecting our own assumptions, consistent with reasonably
available assumptions made by other market participants. These
valuations require significant judgment.</font></p>

<font style="FONT-FAMILY: Times New Roman" size="2">We measure the
fair value of money market funds and equity securities based on
quoted prices in active markets for identical assets or
liabilities. All other financial instruments were valued either
based on recent trades of securities in inactive markets or based
on quoted market prices of similar instruments and other
significant inputs derived from or corroborated by observable
market data. We did not hold any securities categorized as Level 3
as of March 31, 2010, or December 31, 2009.</font></p>

Cash Equivalents, and Marketable Securities
As of
March 31, 2010, and December 31, 2009, our cash, cash
equivalents, andfalsefalsefalseThis item represents the entire disclosure related to Investments in Certain Debt and Equity Securities (and certain other trading assets) which include all debt and equity securities (other than those equity securities accounted for under the equity or cost methods of accounting) with readily determinable fair values. Other trading assets include assets that are carried on the balance sheet at fair value and held for trading purposes. A debt security represents a creditor relationship with an enterprise that is in the form of a security. 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 (and other trading assets).Reference 1: http://www.xbrl.org/2003/role/presentationRef
