3. FAIR VALUE
 
In accordance with 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 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. The remaining 55,000 warrants are classified within the Level 3 hierarchy. The 494,302 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 within the Level 2 hierarchy.
 
As is discussed further in Note 8, on October 1, 2015, the Company issued Series A warrants to purchase an aggregate of 150,000 shares of our common stock at an exercise price of $28.30 per share, and Series B pre-funded warrants to purchase an aggregate of 48,273 shares of our common stock at an offering price of $22.00 per share. These warrants are classified within the Level 3 hierarchy.

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.
