</div>
<div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%">Cash and cash equivalents consist primarily of bank deposits with third-party financial
institutions and highly liquid money market securities with original maturities at date of purchase
of 90 days or less and are stated at cost which approximates fair value.
</div>
<div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%">Short-term investments are recorded at fair value, defined as the exit price in the principal
market in which the Company would transact representing the amount that would be received to sell
an asset or paid to transfer a liability in an orderly transaction between market participants.
Level 1 instruments are valued based on quoted market prices in active markets for identical
instruments and include the Company’s investments in money market funds. Level 2 securities are
valued using quoted market prices for similar instruments, nonbinding market prices that are
corroborated by observable market data, or discounted cash flow techniques and include the
Company’s investments in corporate bonds and notes, U.S. government agency securities, treasury
bills, and commercial paper. Level 3 instruments are valued based on unobservable inputs that are
supported by little or no market activity and reflect the Company’s own assumptions in measuring
fair value. The Company has no short-term investments classified as Level 3 instruments.

<!-- Begin Block Tagged Notefalsefalsefalsefalsefalse | Otherus-types:textBlockItemTypestringThis 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
