2. FAIR VALUE
In accordance with the Fair Value Measurements and Disclosures Topic of the FASB ASC 820, the Company groups its financial assets and financial liabilities generally measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value.
To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.
The Company issued warrants to purchase an aggregate of 82,500 common shares in a February 2013 public offering (the “February 2013 Public Offering Warrants”). On February 20, 2014, 27,500 of the February 2013 Public Offering Warrants expired. On May 20, 2016, 16,250 warrants were exercised. The remaining 38,750 warrants are classified within the Level 3 hierarchy.
In August 2014, as part of an underwritten public offering, the Company issued 494,315 warrants to purchase common stock (the “August 2014 Warrants”). The August 2014 Warrants are listed on the Nasdaq Capital Market under the symbol “CLRBW,” however, there are certain periods where trading volume is low; therefore, they are classified as Level 2 within the hierarchy.
The following tables set forth the Company’s financial instruments carried at fair value using the lowest level of input applicable to each financial instrument as of June 30, 2017 and December 31, 2016:
In order to estimate the value of the February 2013 Public Offering Warrants considered to be derivative instruments, the Company uses a modified option-pricing model together with assumptions that consider, among other variables, the fair value of the underlying stock, risk-free interest rates, volatility, the contractual term of the warrants, future financing requirements and dividend rates. The future financing estimates are based on the Company’s estimates of anticipated cash requirements over the term of the warrants as well as the frequency of required financings based on its assessment of its historical financing trends and anticipated future events. Due to the nature of these inputs and the valuation technique utilized, these warrants are classified within the Level 3 hierarchy.
The following table summarizes the modified option-pricing assumptions used:
During fiscal year 2016, the Company had warrants outstanding for part of the year that were considered financial instruments. Those warrants were either extinguished or amended such that they were no longer considered financial instruments as of December 31, 2016, and were, therefore, not financial instruments during the three or six months ended June 30, 2017. The following table summarizes the modified option-pricing assumptions used for the period they were considered financial instruments:
The following table summarizes the changes in the fair market value of the Company’s warrants which are classified within the Level 3 fair value hierarchy:
In order to estimate the fair value of the August 2014 Warrants, the Company calculated the weighted average closing price for the trailing 10 day period with trades that ended on the balance sheet date.
