6. Fair Value of Financial Assets and Liabilities

Financial instruments, including cash and cash equivalents, prepaid expenses and other receivables, accounts payable and accrued liabilities are carried at cost, which management believes approximates fair value due to the short-term nature of these instruments. The Company measures the fair value of financial assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value.

The Company uses three levels of inputs that may be used to measure fair value:

Level 1 — quoted prices in active markets for identical assets or liabilities

Level 2 — quoted prices for similar assets and liabilities in active markets or inputs that are observable

Level 3 — inputs that are unobservable (for example, cash flow modeling inputs based on assumptions)

The following table presents the Company's assets and liabilities that are measured at fair value at December 31, 2015 and 2014 ($ in thousands):

	Fair value measured at December 31, 2015

Level 3 Valuation Techniques

Level 3 financial liabilities consist of the warrant liabilities for which there is no current market for these securities such that the determination of fair value requires significant judgment or estimation. Changes in fair value measurements categorized within Level 3 of the fair value hierarchy are analyzed each period based on changes in estimates or assumptions and recorded as appropriate.

A significant decrease in the volatility or a significant decrease in the Company’s stock price, in isolation, would result in a significantly lower fair value measurement. Changes in the values of the warrant liabilities are recorded in “change in fair value of warrant liabilities” in the Company’s consolidated statements of operations.

On July 21, 2015, the Company issued the July 2015 Warrants to purchase aggregate of 370,263 shares of common stock to the investors in the July 2015 Financing. The July 2015 Warrants become exercisable on January 22, 2016 at an exercise price of $8.17 per share. The warrants require, at the option of the holder, a net-cash settlement following certain fundamental transactions (as defined in the July 2015 Warrants) at the Company and therefore are classified as liabilities. The July 2015 Warrants have been recorded at their fair value using the Black-Scholes valuation model, and will be recorded at their respective fair value at each subsequent balance sheet date. This model incorporates transaction details such as the Company’s stock price, contractual terms, maturity, risk free rates, as well as volatility.

On December 7, 2015, the Company issued Series A warrants to purchase of 1,052,624 shares of common stock and Series B warrants to purchase 842,099 shares of common stock contained in December Offering. Series A Warrants have an exercise price of $3.80 per share and are exercisable at any time between December 7, 2015 and May 6, 2016. Series B Warrants have an exercise price of $4.75 per share and are exercisable at any time between December 7, 2015 and December 6, 2020. The Warrants require the issuance of registered shares upon exercise, do not expressly preclude an implied right to cash settlement and are therefore accounted for as derivative liabilities.  The Company classifies these derivative warrant liabilities on the consolidated balance sheet as a current liability.

The Series A and Series B warrants have been recorded at their fair value using the Black-Scholes valuation model, and will be recorded at their respective fair value at each subsequent balance sheet date. This model incorporates transaction details such as the Company’s stock price, contractual terms, maturity, risk free rates, as well as volatility.

A summary of quantitative information with respect to the valuation methodology and significant unobservable inputs used for the Company’s warrant liabilities that are categorized within Level 3 of the fair value hierarchy at the date of issuance and as of December 31, 2015 is as follows:

Date of valuation	July 21, 2015		December 7, 2015	December 31, 2015
Risk-free interest rate	1.69	%	0.57 - 1.67%	0.16% - 1.76%
Expected volatility	100.00	%	114.80%	100% - 115.35%
Expected life (in years)	5.5		0.5 - 5.0	0.3 - 5.1
Expected dividend yield	-		-	-

The risk-free interest rate was based on rates established by the Federal Reserve. For the July 2015 Warrants, the expected volatility in the Black-Scholes model is based on an expected volatility of 100% for both periods which represents the percentage required to be used when valuing the cash settlement feature as contractually stated in the form of warrant. The general expected volatility is based on standard deviation of the Company’s underlying stock price's daily logarithmic returns. The expected life of the warrants was determined by the expiration date of the warrants. The expected dividend yield was based upon the fact that the Company has not historically paid dividends on its common stock, and does not expect to pay dividends on its common stock in the future.
