Warrants consist of warrants with the potential to be settled in cash, which are liability-classified warrants, and equity-classified warrants.

Warrants classified as liabilities

Liability-classified warrants consist of warrants issued by Biozone in connection with equity financings in February 2012, August 2013, October 2013 and January 2014, which were assumed by the Company in connection with its merger with Biozone in January 2014. As of December 31, 2016, 4,775,000 warrants are accounted for as liabilities and 1,500,000 warrants are accounted for as equity. Warrants accounted for as liabilities have the potential to be settled in cash or not indexed to the Company’s own stock.

The estimated fair value of outstanding warrants accounted for as liabilities is determined at each balance sheet date. Any decrease or increase in the estimated fair value of the warrant liability since the most recent balance sheet date is recorded in the consolidated statement of operations and comprehensive income (loss) as changes in fair value of derivative liabilities. The fair value of the warrants classified as liabilities is estimated using the Black-Scholes option-pricing model with the following inputs as of December 31, 2016:

	October 2013 warrants			January 2015 warrants

Strike price	$	0.50		$	0.50

Expected term (years)		6.8			7.0
Cumulative volatility %		99.7	%		100	%
Risk-free rate %		2.24	%		2.25	%

The fair value of the warrants classified as liabilities is estimated using the Black-Scholes option-pricing model with the following inputs as of December 31, 2015:

	February 2012 warrants			August 2013 warrants			October 2013 warrants			October 2013 warrants			January 2014 warrants

Strike price	$	0.60		$	0.40		$	0.50		$	0.50		$	0.50

Expected term (years)		0.2			7.7			2.8			7.8			8.0
Cumulative volatility %		81	%		101	%		78	%		101	%		100	%
Risk-free rate %		0.49	%		2.18	%		1.26	%		2.14	%		2.15	%

The Company’s expected volatility is based on a combination of implied volatilities of similar publicly traded entities given that the Company has limited history of its own observable stock price. The expected life assumption is based on the remaining contractual terms of the warrants. The risk-free rate is based on the zero coupon rates in effect at the balance sheet date. The dividend yield used in the pricing model is zero, because the Company has no present intention to pay cash dividends.
