[1] The Company incurred higher costs in the first and fourth quarter of 2013 and the first quarter of 2012 relating primarily to: (i) $1,841,000 and $424,000 of stock and option compensation charges in the 2013 and 2012, respectively, relating to common stock and options granted to directors, employees and consultants, and (ii) $175,000 in the first quarter of 2013 and 2012, respectively, in directors' fees.
[2] Since per share information is computed independently for each quarter and the full year, based on the respective average number of common shares outstanding, the sum of the quarterly per share amounts does not necessarily equal the per share amounts for the year.
