Organization | 1. Organization OvaScience, Inc., incorporated on April 5, 2011 as a Delaware corporation, is a life science company developing proprietary potential treatments for female infertility based on recent scientific discoveries about the existence of egg precursor cells. As used through these consolidated financial statements, the terms "OvaScience," "we," "us," and "our" refer to the business of OvaScience, Inc. and its wholly owned subsidiary. Our operations to date have been limited to organizing and staffing our company, business planning, raising capital, acquiring and developing our technology, identifying potential fertility treatments, developing the AUGMENT treatment, launching the AUGMENT treatment in select international IVF clinics, researching and developing the OvaPrime treatment and the OvaTure treatment, and determining the regulatory and development path for our fertility treatments. We have commenced our planned principal operations but have not generated any significant revenues to date. We are subject to a number of risks similar to other life science companies in the development stage, including, but not limited to, the need to obtain adequate additional funding, possible failure to provide our treatments to IVF clinics to gain clinical experience in select countries outside of the United States, the need to obtain marketing approval for certain of our treatments, competitors developing new technological innovations, the need to successfully commercialize and gain market acceptance of our treatments and protection of proprietary technology. If we do not successfully commercialize any of our treatments, we will be unable to generate treatment revenue or achieve profitability. As of December 31, 2014 we had an accumulated deficit of approximately $94.7 million. Unless otherwise indicated, all information in these financial statements gives retrospective effect to the one-for-2.023 reverse stock split of our common stock (the "Reverse Stock Split") that was effected on March 28, 2012 (see Note 7). Liquidity We have incurred annual net operating losses in each year since our inception. We have not generated any treatment revenues related to our primary business purpose and have financed our operations primarily through private placements of our preferred stock and common stock. We have not completed development of any treatment and have devoted substantially all of our financial resources and efforts to raising capital and research and development. We expect to continue to incur significant expenses and operating losses for at least the next several years. We believe that our cash and cash equivalents and short-term investments of approximately $60.2 million at December 31, 2014, together with the approximately $124.1 million of net proceeds received from our January 2015 secondary public offering, will be sufficient to fund our current operating plan for at least the next 12 months. There can be no assurances, however, that the current operating plan will be achieved or that additional funding, if needed, will be available on terms acceptable to us, or at all.
