Stock options to purchase 259,730 shares of common stock were outstanding and 159,730 were exercisable at December 31, 2015. At December 31, 2015 all outstanding options were included in the diluted earnings per share calculation because the average market price was higher than the exercise price. At December 31, 2014 none of the outstanding options were included in the diluted earnings per share calculation as their effect would have been anti-dilutive.
