Compensation And Retirement Disclosure [Abstract]
Retirement Plan	10. Retirement Plans We began a 401(k) plan for qualified employees on April 1, 2006. The plan is subject to “safe harbor” provisions which require that we match 100.0% of the first 3.0% of employee contributions and 50.0% of the next 2.0% of employee contributions. All employer matching funds vest immediately in accordance with the “safe harbor” provisions. Contributions to the plan for the years ended December 31, 2015, 2014, and 2013 were $40,768, $40,586 and $47,094, respectively.
