The Company intends to file the Form 15 as soon as reasonably practicable in January 2013, subject to its satisfaction of certain regulatory requirements. Ninety days after filing the Form 15, the Company will no longer be obligated to file certain reports with the SEC, including annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K. The Company anticipates that its filing obligations will end after the Company files its annual report on Form 10-K for the year ended December 31, 2012. Recent changes to federal securities laws have made it possible for the Company to suspend its reporting obligations and eliminate the significant costs to the Company associated with preparing annual, quarterly and current reports under the Securities Exchange Act of 1934. In the future, the Company intends to make public its quarterly and annual financial results as well as any significant corporate developments by posting such information on its website. The Company`s common shares have been trading on the OTC Markets, and the Company anticipates its common shares will continue to be quoted on the OTC Markets after deregistration. There can be no guarantee, however, that any broker will continue to make a market in the Company`s common shares and that trading will continue.
