The Company determined the grant-date fair value of the options using the Black-Scholes valuation model with the following weighted-average assumptions:

	Three Months Ended June 30, 2017		Six Months Ended June 30, 2017
Expected volatility(1)	63.0	%	63.0	%
Expected dividend yield	—	%	—	%
Expected term (in years)(2)	6.25		6.25
Risk-free interest rate	1.9	%	1.9	%

(1) Measured using selected high-growth guideline companies and considering the risk factors that would influence the range of expected volatility because the Company does not have sufficient historical data to provide a reasonable basis upon which to estimate the expected volatility.

(2) Expected term represents the estimated period of time until an option is exercised and was determined using the simplified method because the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term.
