Earnings Per Share [Abstract]
Earnings Per Share	7. Earnings Per Share The calculation of basic earnings per share excludes any dilutive effect of stock options and convertible debt, while diluted earnings per share includes the dilutive effect of options and convertible debt. The number of dilutive shares excluded from this calculation resulting from the antidilutive effect of options is 512,466 for the three months ended June 30, 2010 and 419,367 and 511,335 for the six months ended June 30, 2011 and 2010, respectively. Diluted earnings per share should also reflect the potential dilution that could occur if the Company’s convertible debt was converted to common stock. The number of potentially dilutive shares related to the Company’s convertible debt excluded from the calculation because of their antidilutive effect is 49,125 and 57,646 for the three and six months ended June 30, 2010, respectively.
