Earnings Per Share [Abstract]  
Net Income Per Share
Net Income Per Share
          Basic net income per common share is computed by dividing the net income relevant to the common stockholders by the weighted-average number of shares outstanding during the period. Diluted net income per common share uses the same net income divided by the sum of the weighted-average number of shares of common stock outstanding during the period, plus dilutive effects of options, performance and restricted stock units outstanding during the period calculated using the treasury method and the potential dilutive effects of preferred stocks (if any) calculated using the if-converted method.
          The table below shows the calculations for the three and nine months ended September 30, 2018 and 2017.
