Schedule of assumptions used to determine the fair value of options as of the grant date

The fair value of the service-based options was determined using the Black-Scholes option pricing model and the fair value of the market-based options was determined using a lattice (binomial) model. The following assumptions were used to determine the fair value as of the grant date:

	Three months ended   March 31, 2016		Three months ended   March 31, 2015
	Black-Scholes	Binomial	Black-Scholes		Binomial
Risk-free interest rate (%)	1.25% - 1.89%	0.23% - 1.97%	1.67	%	0.02% - 2.01%
Expected stock price volatility (%)	59.75% - 62.14%	59.76% - 62.14%	55.06	%	55.06	%
Expected dividend yield	—	—	—		—
Expected option life (in years)	6.25	4.55 - 4.88	6.25		4.45 - 4.92
Fair value	$11.15 - $16.30	$11.06 - $15.73	$11.69		$10.68 - $11.93
