12. Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents and warrants. General accounting principles for fair value measurement established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (“Level 1”) and the lowest priority to unobservable inputs (“Level 3”). The three levels of the fair value hierarchy are described below:

Level 1: Values are based on unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2: Values are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, or other model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3: Values are generated from model-based techniques that use significant assumptions not observable in the market.

The following table sets forth the Company’s assets and liabilities measured at fair value on a recurring basis by level within the fair value hierarchy. As required by the Fair Value Measurements and Disclosures topic of the Accounting Standards Codification, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Total liabilities at fair value:	$	2,134,187	—	—	2,134,187

Level 1

The Company’s financial assets consist of cash equivalents invested in money market funds in the amount of $524,083 and $5,361,053 at December 31, 2015 and December 31, 2014, respectively. These assets are classified as Level 1 as described above and total interest income recorded for these investments was insignificant during both the years ended December 31, 2015 and December 31, 2014. There were no transfers in or out of Level 1 during the year ended December 31, 2015.

Level 2

The Company does not have any financial assets or liabilities classified as Level 2.

Level 3

Due to provisions included in the warrant agreements, outstanding warrants related to the Company’s May 2012 Stock and Warrant Purchase Agreement (“PIPE warrants”) do not meet the exemptions for equity classification and as such, the Company accounts for these PIPE warrants as derivative instruments. The PIPE warrants are periodically remeasured with any changes in value recognized in “Other income (expense)” in the Statement of Operations.

The remaining PIPE warrants expire in May 2018 and were valued using an option pricing model as of December 31, 2014 using the following assumptions: 1) volatility of 165.27%; 2) risk-free interest rate of 1.10%; and 3) a closing stock price of $1.48.

The PIPE warrants were revalued using an option pricing model as of December 31, 2015 using the following assumptions: 1) volatility of 113.4%; 2) risk-free interest rate of 1.06%; and 3) a closing stock price of $0.74.

Due to the provisions included in the warrant agreements, warrants outstanding in conjunction with the Company’s August 7, 2013 transaction (the “Exchange warrants”) also do not meet the exemptions for equity classification and as such, the Company accounts for these warrants as derivative instruments.

The remaining Exchange warrants expire in November 2018 and were valued using an option pricing model as of December 31, 2014 using the following assumptions: 1) volatility of 158.08%; 2) risk-free interest rate of 1.10%; and 3) a closing stock price of $1.48.

The Exchange warrants were revalued using an option pricing model as of December 31, 2015 using the following assumptions: 1) volatility of 182.94%; 2) risk-free interest rate of 1.31%; and 3) a closing stock price of $0.74.

The significant unobservable input used in the fair value measurement of the Company’s warrants is volatility. Significant increases (decreases) in the volatility in isolation would result in a significantly higher (lower) liability fair value measurement.

The following table sets forth a summary of changes in the fair value of the Company’s Level 3 financial liabilities for the year ended December 31, 2015:


	Warrants issued May 2012	Warrants issued August 2013	Total Liabilities
Balance at beginning of period	$ 728,712	$ 1,405,475	$ 2,134,187
Issues	-	-	-
Settlements	-	-	-
Revaluation	(585,031)	(755,026)	(1,340,057)
Balance at end of period	$ 143,681	$ 650,449	$ 794,130

The Company currently does not have derivative instruments to manage its exposure to currency fluctuations or other business risks. The Company evaluates all of its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. All derivative financial instruments are recognized in the balance sheet at fair value.
