We estimate the fair value of such warrants on the date of grant using a Black-Scholes pricing model, applying the following assumptions, and amortize the fair value to interest expense over the term of the Term Loan using the interest method:

		Year Ended December 31,
		2016				2015
Expected term (in years)		10				10
Risk-free interest rate			1.56	%			2.24	%
Expected volatility			90.47	%			114.33	%
Expected dividend yield			0.00	%			0.00	%

Scheduled Future Maturities of Total Debts

Excluding potential additional principal payments due on the Term Loans based on excess cash flows for the immediately preceding fiscal year, as mentioned above, scheduled future maturities of total debts as of December 31, 2016, were as follows:

(In thousands)
