For the year ended December 31, 2015, there were 1,448,000 stock options which were anti-dilutive and therefore were not considered in computing diluted earnings per share (December 31, 2014 – 1,765,920; December 31, 2013 - 863,414). c) Share purchase programs On August 14, 2015, the Company commenced a normal course issuer bid in Canada through the facilities of the Toronto Stock Exchange ("TSX"), to purchase up to 532,520 voting common shares (the "NCIB") that terminated on December 17, 2015. As at December 31, 2015, a total of 532,520 common voting shares were purchased and subsequently cancelled in the normal course resulting in a reduction of $4,500 to common shares and an increase to additional paid-in capital of $2,948. On December 18, 2014, the Company commenced purchasing and subsequently canceling 1,771,195 voting common shares (the "Purchase Program"), in the United States primarily through the facilities of the New York Stock Exchange ("NYSE"). Such voting common shares represented approximately 5% of the issued and outstanding voting common shares as of December 10, 2014. In June 2015, the Company completed the share purchase program canceling 1,271,195 voting common shares in the current year resulting in a reduction of $10,917 to common shares and an increase to additional paid-in capital of $6,284. As at December 31, 2015, a total of 1,771,195 common shares had been purchased and subsequently cancelled in the normal course. As at December 31, 2014, a total of 500,000 voting common shares had been purchased and subsequently cancelled in the normal course resulting in a reduction of $4,238 to common share and an increase to additional paid-in capital of $2,297. d) Dividends On February 19, 2014, it was announced that as part of the Company's long term goal to maximize shareholders' value and broaden our shareholder base, the Board of Directors approved the implementation of a new dividend policy. The Company intends to pay an annual aggregate dividend of eight Canadian cents ($0.08) per common share, payable on a quarterly basis. Under the original dividend policy, the record date for payment was set on the last day of each quarter, with payment distributed in the following month. On November 2, 2015, the Board of Directors resolved to change the dividend policy to move record dates and payment dates approximately one month earlier, thus allowing the Company to make payment in the same quarter a dividend is declared. This change resulted in a dividend payment in December 2015 that, under the old policy, would have been made in January of 2016. In total, the Company paid regular quarterly cash dividends of $0.02 per share on common shares during the year ended December 31, 2015 on each of the following dates: January 23, 2015; April 24, 2015; July 24, 2015; October 23, 2015; and December 11, 2015.
