Since the Company’s inception, it has incurred significant losses and, as of June 30, 2012 (unaudited), it had an accumulated deficit of $56.5 million. The Company has funded its operations primarily with customer payments for its products and services, proceeds from the issuances of convertible preferred stock, proceeds from the issuance of common stock in connection with its IPO, borrowings under its term loan facility and the utilization of its line of credit. From inception, the Company has sold an aggregate of $52.8 million of its convertible preferred stock net of issuance costs. As of June 30, 2012 (unaudited), the Company had cash, cash equivalents and short-term investments of $79.8 million. The Company believes that its existing sources of liquidity will satisfy its working capital and capital requirements for at least the next 12 months. Failure to generate sufficient revenue, achieve planned gross margins, or control operating costs may require the Company to raise additional capital through equity or debt financing. Such additional financing may not be available on acceptable terms, or at all, and could require the Company to modify, delay or abandon some of its planned future expansion or expenditures or reduce some of its ongoing operating costs, which could harm its business, operating results, financial condition and ability to achieve its intended business objectives. If the Company raises additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, its existing stockholders could suffer significant dilution in their percentage ownership of the Company and any new securities it issues could have rights, preferences and privileges senior to those of holders of its common stock.
