Except as set forth below, there have been no material changes from the risk factors set forth under the heading “Risk Factors” in Part I, Item 1A in our Annual Report. An investment in shares of our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described in our Annual Report, together with all of the other information in the Annual Report, together with the other information appearing elsewhere in this Quarterly Report, including our unaudited condensed consolidated financial statements and related notes hereto, and any other documents that we file with the SEC before deciding to invest in our common stock. The occurrence of any of the following risks or of those described in our Annual Report could have a material adverse effect on our business, financial condition, results of operations, and future growth prospects or cause our actual results to differ materially from those contained in forward-looking statements we have made in this report and those we may make from time to time. In these circumstances, the market price of our common stock could decline; and you may lose all or part of your investment. We cannot assure you that any of the events discussed in our Annual Report will not occur. Risks Related to Our Common Stock and CDIs The market price of our CDIs and common stock has been, and may in the future be, volatile, or may decline regardless of our operating performance and you could lose all or part of your investment. The trading price of our CDIs on the ASX and of our common stock on the Nasdaq Global Select Market (“Nasdaq”) has been and may continue to be volatile, and could be subject to wide fluctuations. In addition, the trading volume in our CDIs and common stock has in the past and may in the future fluctuate and cause significant price variations to occur. Securities markets worldwide experience significant price and volume fluctuations as a result of a variety of factors, many of which are beyond our control but may nonetheless decrease the market price of our CDIs and common stock, regardless of our actual operating performance, including: •public reaction to our press releases, announcements, and filings with the SEC and ASX; •our operating and financial performance; •fluctuations in market prices and trading volumes of technology; •changes in market valuations of similar companies; •departures of key personnel; •commencement of or involvement in litigation; •changes in economic and political conditions, financial markets, and/or the technology industry; •interest rate fluctuations; •changes in accounting standards, policies, guidance, interpretations, or principles; •actions by our securityholders; •the failure of securities analysts to cover our common stock and/or changes in their recommendations and estimates of our financial performance; 48 Table of Contents •future sales of our common stock; •the timing, price, and volume of repurchases under our share repurchase program, or any determination to suspend, modify, or discontinue the program; •trading prices and trading volumes of our CDIs on the ASX and our common stock on the Nasdaq; and •the other factors described in these “Risk Factors”. The stock market has in the past experienced extreme price and volume fluctuations, and, following periods of such volatility in the overall market and the market price of a company’s securities, securities class action litigation has often been instituted against these companies. Such litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources, which would harm our business, operating results, or financial condition. Our common stock is currently listed on Nasdaq and our CDIs are currently listed on the ASX. Trading in our common stock and CDIs therefore takes place in different currencies (U.S. dollars on the Nasdaq and Australian dollars on the ASX), and at different times (resulting from different time zones, different trading days and different public holidays in the U.S. and Australia). The trading prices of our common stock and our CDIs on two markets may differ as a result of these, or other, factors. Any decrease in the price of our common stock or CDIs on either market could cause a decrease in the trading prices of our CDIs or our common stock on the other market. In addition, investors may seek to profit by exploiting the difference, if any, between the price of our common stock on Nasdaq and the price of our CDIs on the ASX. Such arbitrage activities could cause our stock price in the market with the higher value to decrease to the price set by the market with the lower value and could also lead to significant volatility in the price of our common stock or CDIs. With respect to our share repurchase program, there is no guarantee that the program will be fully consummated or that it will enhance long-term stockholder value, and repurchases under the program could increase the volatility of the trading price of our common stock or CDIs, or negatively impact our cash reserves. Repurchases under the program, and any Company Rule 10b5-1 trading plan, may be modified, suspended, or discontinued without prior notice.
