Suspension Of Duty To File Reports With The SEC [Abstract]
Suspension Of Duty To File Reports With The SEC	14. Suspension of Duty to File Reports with the SEC On August 15, 2011, we filed a Form 15 (the "Original Form 15") with the Securities and Exchange Commission (the "SEC") certifying that, as of such date, there were fewer than 300 holders of record of our common stock. The Original Form 15 had the effect of terminating the registration of our common stock under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), which was the first step in suspending our obligation to file current and periodic reports with the SEC. However, our duty to file current and periodic reports with the SEC was not suspended immediately upon filing the Original Form 15, due to the prior filing of certain registration statements under the Securities Act of 1933, as amended (the "Securities Act") that were deemed to have been made effective during the fiscal year ended December 31, 2011 by the filing of our Annual Report on Form 10-K for the fiscal year ended December 31, 2010, which we filed with the SEC on March 30, 2011. As a result, following the filing of the Original Form 15, on October 28, 2011we filed a Current Report on Form 8-K, and on November 7, 2011 we filed a Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2011. In addition, we are filing this Annual Report on Form 10-K for the fiscal year ended December 31, 2011. However, we have taken certain actions required by SEC rules to ensure that we are not required by the Exchange Act to file current or periodic reports with the SEC with respect to the fiscal year ending December 31, 2012, which actions have included the filing of post-effective amendments to each of our registration statements filed under the Securities Act to terminate such registration statements (which post-effective amendments have been declared effective by the SEC), and the filing, on January 12, 2012, of a Form 15 to notify the SEC that we had fewer than 300 holders of record of our common stock as of December 31, 2011. In addition, we do not expect that we will be required to file current or periodic reports with the SEC with respect to any fiscal year following the fiscal year ending December 31, 2012.
