2. Basis of Presentation and Significant Accounting Policies
Basis of Presentation
The condensed consolidated financial statements include the accounts of XOMA and its subsidiaries. All intercompany accounts and transactions were eliminated during consolidation. The unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q. These financial statements and related disclosures have been prepared with the assumption that users of the interim financial information have read or have access to the audited financial statements for the preceding fiscal year. Accordingly, these statements should be read in conjunction with the audited consolidated financial statements and related notes included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2011, filed with the U.S. Securities and Exchange Commission ("SEC") on March 14, 2012.
In the opinion of management, the unaudited condensed consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, which are necessary to present fairly the Company's consolidated financial position as of June 30, 2012, the consolidated results of the Company's operations and the Company's cash flows for the three and six months ended June 30, 2012 and 2011. The interim results of operations are not necessarily indicative of the results that may occur for the full fiscal year or future periods.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosures. On an on-going basis, management evaluates its estimates including, but not limited to, those related to contingent warrant liabilities, revenue recognition, research and development expense, long-lived assets, restructuring liabilities, derivative instruments and stock-based compensation. The Company bases its estimates on historical experience and on various other market-specific and other relevant assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ significantly from these estimates, such as the Company's billing under government contracts. Under the Company's contracts with the National Institute of Allergy and Infectious Diseases ("NIAID"), a part of the National Institutes of Health ("NIH"), the Company bills using NIH provisional rates and thus are subject to future audits at the discretion of NIAID's contracting office. These audits can result in an adjustment to revenue previously reported.
At March 31, 2012, the Company changed its expected volatility assumption in the Black-Scholes Option Pricing Model ("Black-Scholes Model") used to calculate the fair value of its contingent warrant liabilities. The Company changed its assumption 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, which was determined to be a more precise indicator for the fair value calculation of the Company's warrants.
Reclassifications
Certain reclassifications of prior period amounts have been made to the financial statements and accompanying notes to conform to the current period presentation. Prior period presentation of contingent warrant liabilities has been reclassified from current liabilities to long-term liabilities based on the contingent nature of these obligations. These contingent warrant liabilities represent a conditional obligation of the Company to repurchase certain warrants for cash in the event of a change in control. In addition, gain or loss on revaluation of the contingent warrant liabilities included in the other income (expense) line of the condensed consolidated statements of comprehensive loss in the prior period has been reclassified to the revaluation of contingent warrant liabilities line of the condensed consolidated statements of comprehensive loss. These reclassifications had no impact on the Company's previously reported net loss or cash flows.
Long-lived Assets
The Company reviews the carrying values and depreciation estimates of its long-lived assets whenever events or changes in circumstances indicate that the asset may not be recoverable. An impairment loss is recognized when the estimated future net cash flows expected to result from the use of an asset is less than its carrying amount. Long-lived assets include property and equipment and building and leasehold improvements. During the first quarter of 2012, the Company recorded accelerated depreciation of $0.4 million and $1.3 million, respectively, on long-lived assets in connection with the Company's 2012 streamlining plan. During the first quarter of 2012, the Company recorded an impairment losses of $0.8 million. The Company did not book an impairment loss in the second quarter of 2012. See Note 6: Streamlining and Restructuring Charges for additional disclosure on the 2012 streamlining plan.
Concentration of Risk
Cash equivalents, short-term investments and receivables are financial instruments, which potentially subject the Company to concentrations of credit risk, as well as liquidity risk for certain cash equivalents such as money market funds. The Company has not encountered such issues during 2012.
The Company has not experienced any significant credit losses and does not generally require collateral on receivables. For the six months ended June 30, 2012, two customers represented 41% and 37% of total revenue and 42% and 50% of the accounts receivable balance.
For the six months ended June 30, 2011, these two customers represented 57% and 38% of total revenues. As of December 31, 2011, there were receivables outstanding from these two customers representing 57% and 43% of the accounts receivable balance.
Newly Adopted Accounting Pronouncements
In May 2011, Accounting Standards Codification Topic 820, Fair Value Measurement was amended to develop common requirements for measuring fair value and for disclosing information about fair value measurements in accordance with U.S. generally accepted accounting principles and international financial reporting standards. The Company adopted this guidance as of January 1, 2012 on a retrospective basis and this adoption did not have a material effect on the Company's consolidated financial statements.
In June 2011, Accounting Standards Codification Topic 220, Comprehensive Income was amended to increase the prominence of items reported in other comprehensive income. Accordingly, a company can present all nonowner changes in stockholders' equity either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The Company adopted this guidance as of January 1, 2012 on a retrospective basis and this adoption did not have a material effect on the Company's consolidated financial statements.
