11. Warrant Liability

The common stock purchase warrants issued to the underwriters in the Company's IPO in March 2013 have certain cash settlement features that require them to be recorded as liability instruments. At issuance, a portion of the proceeds from the IPO were allocated to the value of the warrant and recorded as an offering cost, reducing the proceeds from the IPO. Accordingly, as a liability, the warrant obligations are adjusted to fair value at the end of each reporting period with the change in value reported in the statement of operations. Such fair values were estimated using the Black-Scholes valuation model. The Company will continue to adjust the warrant liability for changes in fair value until the earlier of the exercise, at which time the liability will be reclassified to stockholders' equity, or expiration of the warrants.

The warrant liability was valued using the Black-Scholes option valuation model and the following assumptions on the following dates:
December 31,
March 4,
Strike price
  $ 10.00     $ 10.00  
Market price
  $ 4.61     $ 8.00  
Expected life
5.17 years
6.00 years
Risk-free interest rate
    0.86 %     0.86 %
Dividend yield
    0.00 %     0.00 %
    39 %     48 %
Warrants outstanding
    131,250       131,250  
Fair value of warrants
  $ 85,221     $ 415,368  

The fair value of the warrant liability decreased to $85,221 at December 31, 2013 from $415,368 at March 4, 2013. Accordingly, the Company decreased the warrant liability by $330,147 to reflect the change in the fair value of the warrant instruments for the period ended December 31, 2013, which is included in the accompanying statements of comprehensive (loss) income for the year ended December 31, 2013. The following table sets forth a summary of the changes in the fair value of our Level 3 financial liabilities that are measured at fair value on a recurring basis:
