|Fair Value Measurements [Abstract]|
|Fair Value Measurements||
Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies ASC 820, which establishes a framework for measuring fair value and a fair value hierarchy that prioritizes the inputs used in valuation techniques. ASC 820 describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following:
The following tables set forth the Company's fair value hierarchy for its financial assets (cash equivalents) and liabilities measured at fair value on a recurring basis as of March 31, 2012 and December 31, 2011.
Financial assets and liabilities carried at fair value as of March 31, 2012 and December 31, 2011 were classified as follows (in thousands):
(1) Included in cash and cash equivalents
The fair value of the foreign exchange options at March 31, 2012 and December 31, 2011 was determined using readily observable market inputs from actively quoted markets obtained from various third party data providers. These inputs, such as spot rate, forward rate and volatility have been derived from readily observable market data, meeting the criteria for Level 2 in the fair value hierarchy.
The fair value of the contingent warrant liabilities was determined at March 31, 2012 and December 31, 2011 using the Black-Scholes Model, which requires inputs such as the expected term of the warrants, volatility and risk-free interest rate. These inputs are subjective and generally require significant analysis and judgment to develop. 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. A market-based volatility rate was determined to be a more precise indicator for the fair value calculation of the Company's warrants.
The fair value of the contingent warrant liabilities was estimated using the following range of assumptions at March 31, 2012 and December 31, 2011:
The following table provides a summary of changes in the fair value of the Company's Level 3 financial liabilities for the three months ended March 31, 2012 (in thousands):
The net increase of $14.4 million in the estimated fair value of the contingent warrant liabilities was recognized as a loss in the revaluation of contingent warrant liabilities line of the condensed consolidated statements of operations for the three months ended March 31, 2012.
For the three months ended March 31, 2011, the Company recognized a net decrease of $2.4 million in the estimated fair value of the contingent warrant liabilities as a gain in the revaluation of contingent warrant liabilities line of the condensed consolidated statements of operations.
The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.
