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 among consolidated entities were eliminated during consolidation. The unaudited financial statements were prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q
In management's opinion, the accompanying 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 March 31, 2014, the consolidated results of the Company's operations and the Company's cash flows for the three months ended March 31, 2014 and 2013. The interim results of operations are not necessarily indicative of the results that may be expected for the full fiscal year or any other 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, 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.
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 presentations of net product sales has been reclassified into contract and other revenue, and cost of sales has been reclassified into research and development expense, because the net product sales were not material for all periods presented. These reclassifications had no impact on the Company's previously reported net loss or cash flows.
Concentration of Risk
Cash equivalents 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 2014.
The Company has not experienced any significant credit losses and does not generally require collateral on receivables. For the three months ended March 31, 2014, three customers represented 47%, 40%, and 15% of total revenue and 57%, 28%, and 12% of the accounts receivable balance.
For the three months ended March 31, 2013, two customers represented 79% and 18% of total revenues. As of December 31, 2013, there were receivables outstanding from these two customers representing 73% and 13% of the accounts receivable balance.
