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.
  
·
Level 1: Input prices quoted in an active market for identical financial assets or liabilities.
·
Level 2: Inputs other than prices quoted in Level 1, such as prices quoted for similar financial assets and liabilities in active markets, prices for identical assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data.
·
Level 3: Input prices quoted that are significant to the fair value of the financial assets or liabilities which are not observable or supported by an active market.
 
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 had issued warrants to purchase 1,365 shares of common stock in July 2010 (“July 2010 Warrants”) that are classified within the Level 2 hierarchy. In February 2013, the Company issued warrants in a public offering (“February 2013 Public Offering Warrants”), of which 550,000 warrants are outstanding, and are classified within the Level 3 hierarchy. In August 2014, the Company issued 4,943,023 warrants as part of a public offering (the “August 2014 Warrants”) which are listed on the NASDAQ Capital Market under the symbol “CLRBW”. There are certain periods, however, when trading volume of the August 2014 Warrants is low, causing them to be classified within the Level 2 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, 2015 and December 31, 2014:

In order to estimate the fair value of the July 2010 Warrants, the Company uses the Black-Scholes option pricing model and assumptions that consider, among other variables, the fair value of the underlying stock, risk-free interest rate, volatility, expected life and dividend rates. Assumptions used are generally consistent with those disclosed for stock-based compensation (see Note 5).
 
In order to estimate the value of the February 2013 Public Offering Warrants considered to be derivative instruments as of June 30, 2015, 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 rate of .88%, volatility of 90%, remaining contractual term of 2.64 years, 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 assumptions used to estimate the value of the February 2013 Public Offering Warrants as of December 31, 2014 include the fair value of the underlying stock, risk free interest rates ranging from 1.07% to 2.63%, volatility ranging from 100% to 115%, the contractual term of the warrants ranging from 3.14 to 3.89 years, future financing requirements and dividend rates.
 
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.
