Shareholders' Equity | 8. Shareholders’ Equity . Stock-Based Compensation . The Company’s stock-based compensation plans are administered by the Compensation Committee of the Board of Directors, which selects persons to receive awards and determines the number of shares subject to each award and the terms, conditions, performance measures and other provisions of the award. The following table summarizes the stock-based compensation expense that was recognized in the Company’s statements of comprehensive income for the years ended December 31, 2015 and 2014: Year ended December 31 2015 2014 Cost of sales $ $ Selling Marketing General and administrative $ $ The Company uses the Black-Scholes option-pricing model to estimate fair value of stock-based awards with the following weighted average assumptions: 2015 2014 Stock Options: Expected life (years) Expected volatility % % Dividend yield % % Risk-free interest rate % % 2015 2014 Stock Purchase Plan Options: Expected life (years) Expected volatility % % Dividend yield % % Risk-free interest rate % % The Company uses the graded attribution method to recognize expense for unvested options and restricted stock units. The amount of stock-based compensation recognized during a period is based on the value of the awards that are ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company re-evaluates the forfeiture rate annually and adjusts it as necessary. As of December 31, 2015, there was approximately $120,000 of total unrecognized compensation costs related to the outstanding stock options, which is expected to be recognized over a weighted average period of 1.8 years.
