Warrants	4. Warrants In September 2013, in connection with a private placement of common stock and warrants, the Company issued five-year warrants to purchase 1,421,698 shares of CymaBay’s common stock at an exercise price of $5.75 per share. The Company also issued five-year warrants to purchase 121,739 shares of CymaBay’s common stock at an exercise price of $5.00 per share. These warrants contain provisions that are contingent on the occurrence of a change in control, which would conditionally obligate the Company to repurchase the warrants for cash in an amount equal to their fair value using the Black-Scholes Option Pricing Model (the “Black-Scholes Model”) on the date of such change in control. Due to these provisions, the Company is required to account for the warrants issued in September 2013 as a liability at fair value. In addition, the estimated liability related to the warrants is required to be revalued at each reporting period until the earlier of the exercise of the warrants, at which time the liability will be reclassified to stockholders’ equity, or expiration of the warrants. At issuance date, the fair value of the total warrant liability was estimated to be $5.3 million using the Black-Scholes Model.
