Note 12. Subsequent Events	On October 24, 2012, the Company received notification from the NYSE MKT (the "Exchange") stating that, because the Company was not in compliance with certain of the Exchange's continued listing standards, the Exchange intended to strike the common stock of the Company from the Exchange by filing a delisting application with the Securities and Exchange Commission (the "SEC"). The Company previously disclosed in Current Reports on Form 8-K filed with the SEC on April 20, 2012, May 29, 2012, July 6, 2012, and October 24, 2012 the provisions of the Exchange's continued listing standards with which the Company was not in compliance. The Company requested an appeal of the Exchange's delisting determination, which hearing before the Committee on Securities has been scheduled on December 19, 2012. Effective October 31, 2012, trading of the Company’s common shares ceased on the Exchange and, on the same date, trading of the Company’s shares commenced on the OTCQB Marketplace under the trading symbol "ENVS". The OTCQB is a market tier operated by the OTC Market Group Inc. for over-the-counter traded companies. The Company anticipates that the delisting will be completed once the Exchange files a Form 25-NSE Notification of Delisting with the SEC. The delisting and transition to the OTCQB does not change the Company's obligations to file periodic and other reports with the SEC under applicable federal securities laws. The admission of the Company’s common stock for trading on London Stock Exchange's AIM market is unaffected by the NYSE MKT's determination.
