Comprehensive Loss

Comprehensive loss is equal to net loss for both the three months ended March 31, 2012 and 2011.

Net Loss Per Share of Common Stock

Basic and diluted net loss per share of common stock is based on the weighted average number of shares of common stock outstanding during the period.

 

Potentially dilutive securities are excluded from the calculation of earnings per share if their inclusion is anti-dilutive. The following table shows the total outstanding securities considered anti-dilutive and therefore excluded from the computation of diluted net loss per share (in thousands):

For the three months ended March 31, 2012 and 2011, all outstanding securities were considered anti-dilutive, and therefore the calculation of basic and diluted net loss per share was the same.

Cash and Cash Equivalents

At March 31, 2012 cash equivalents consisted of demand deposits of $14.4 million, money market funds of $50.5 million, and U.S. government securities of $10.0 million with maturities of less than 90 days at the date of purchase. At December 31, 2011, cash equivalents consisted of demand deposits of $21.1 million and money market funds of $27.2 million with maturities of less than 90 days at the date of purchase.

Foreign Exchange Options

The Company holds debt and may incur expenses denominated in foreign currencies, which exposes it to market risk associated with foreign currency exchange rate fluctuations between the U.S. dollar and the Euro. The Company is required to make principal and accrued interest payments in Euros on its €15.0 million loan from Servier (See Note 7: Long-Term Debt and Other Financings). In order to manage its foreign currency exposure related to these payments, in May 2011, the Company entered into two foreign exchange option contracts to buy €15.0 million and €1.5 million on January 2016 and January 2014, respectively. By having these option contracts in place, the Company's foreign exchange rate risk is reduced if the U.S. dollar weakens against the Euro. However, if the U.S. dollar strengthens against the Euro, the Company is not required to exercise these options, but will not receive any refund on premiums paid.

Upfront premiums paid on these foreign exchange option contracts totaled $1.5 million. The fair values of these option contracts are re-valued at each reporting period and are estimated based on pricing models using readily observable inputs from actively quoted markets. The fair values of these option contracts are included in other assets on the condensed consolidated balance sheet and changes in fair value on these contracts are included in other income (expense) on the condensed consolidated statements of operations.

The foreign exchange options were revalued at March 31, 2012 and had an aggregate fair value of $0.9 million resulting in a related loss of $0.3 million for the three months ended March 31, 2012.

Accrued Liabilities

Accrued liabilities consisted of the following at March 31, 2012 and December 31, 2011 (in thousands):

 

Contingent Warrant Liabilities

 

In March 2012, in connection with an underwritten offering, the Company issued five-year warrants to purchase 14,834,577 shares of XOMA's common stock at an exercise price of $1.76 per share. These warrants contain provisions that are contingent on the remote 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 Model on the date of such change in control. Due to these provisions, the Company is required to account for the warrants issued in March 2012 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, the fair value of the warrant liability was estimated to be $6.4 million using the Black-Scholes Model. The Company revalued the warrant liability at March 31, 2012 using the Black-Scholes Model and recorded an increase in the fair value of $14.7 million as a loss in the revaluation of contingent warrant liabilities line of the condensed consolidated statement of operations. As of March 31, 2012, 14,832,827 of these warrants were outstanding and had a fair value of $21.1 million. This increase in liability is primarily due to the excess of the market value of the Company's common stock at March 31, 2012 compared to the warrant exercise price. See Note 4: Fair Value Measurements for further disclosure regarding the fair value of this warrant liability.

In February 2010, in connection with an underwritten offering, the Company issued five-year warrants to purchase 1,260,000 shares of XOMA's common stock at an exercise price of $10.50 per share. These warrants contain provisions that are contingent on the remote 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 Model on the date of such change in control. Due to these provisions, the Company is required to account for the warrants issued in February 2010 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 December 31, 2011, the fair value of the warrant liability was estimated to be $0.3 million using the Black-Scholes Model. At March 31, 2012, the Company changed its expected volatility assumption in the Black-Scholes Model from an estimate of volatility based on historical stock price volatility observed on XOMA's underlying stock to a volatility estimate based on the volatility implied from warrants issued by XOMA in recent private placement transactions. The Company revalued the warrant liability at March 31, 2012 using the Black-Scholes Model and recorded a decrease in the fair value of $0.3 million as a gain in the revaluation of contingent warrant liabilities line of the condensed consolidated statement of operations. As of March 31, 2012, all of these warrants were outstanding. See Note 4: Fair Value Measurements for further disclosure regarding the fair value of this warrant liability.

In June 2009, the Company issued warrants to certain institutional investors as part of a registered direct offering. The warrants represent the right to acquire an aggregate of up to 347,826 shares of XOMA's common stock over a five year period beginning December 11, 2009 at an exercise price of $19.50 per share. These warrants contain provisions that are contingent on the remote 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 Model on the date of such change in control. Due to these provisions, the Company is required to account for the warrants issued in June 2009 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 December 31, 2011, the fair value of the warrant liability was estimated to be $0.1 million using the Black-Scholes Model. At March 31, 2012, the Company changed its expected volatility assumption in the Black-Scholes Model from an estimate of volatility based on historical stock price volatility observed on XOMA's underlying stock to a volatility estimate based on the volatility implied from warrants issued by XOMA in recent private placement transactions. The Company revalued the warrant liability at March 31, 2012 using the Black-Scholes Model and recorded a decrease in the fair value of $0.1 million as a gain in the revaluation of contingent warrant liabilities line of the condensed consolidated statement of operations. As of March 31, 2012, all of these warrants were outstanding. See Note 4: Fair Value Measurements for further disclosure regarding the fair value of this warrant liability.
