Schedule of Share-based Payment Award, Employee Stock Purchase Plan, Valuation Assumptions

The Company uses a Black-Scholes valuation model to estimate the fair value of the options at grant date based on the assumptions noted in the following table.  Volatility represents an average of market estimates for implied volatility of the Company's common stock.  The expected life is estimated based on an analysis of options already exercised and any foreseeable trends or changes in recipients' behavior.  The risk-free interest rate is an interpolation of the relevant U.S. Treasury security maturities as of each applicable grant date:

	Years ended December 31,
	2016	2015
Risk-free interest rates	1.53%	0.93 - 2.04%
Dividend yield	0%	0%
Expected life	7.00 years	3.03 - 7.00 years
Volatility	49.05%	45.94 - 49.44%
Weighted average volatility	49.05%	47.45%

Restricted Stock Units

During the years ended December 31, 2016 and 2015, the Company issued RSUs to employees which vest upon the achievement of specific market-based or time-based measures.  The fair value for RSU's is calculated based on the stock price on the grant date and expensed ratably over the requisite service period, which ranges between one and five years.  The following table summarizes the information about vested and unvested restricted stock units for the years ended December 31, 2016 and 2015.
