Loss Per Common Share
  
The effect of options, restricted stock and restricted stock units that were excluded from the calculation of diluted weighted average shares outstanding because the exercise price or grant price of the securities exceeded the average market price of the Company's common stock were: 1.0 million shares of common stock for the year ended December 31, 2015, and 0.8 million shares of common stock for each of the years ending December 31, 2014 and December 31, 2013. The weighted average share impacts of options, restricted stock and restricted stock units that were excluded from the calculation of weighted average shares due to the Company's incurring a net loss for the three years ending December 31, 2015, 2014 and 2013 were not significant.
