Basis of Presentation

1. Basis of Presentation

The information contained herein has been prepared by Novatel Wireless, Inc. (the “Company”) in accordance with the rules of the Securities and Exchange Commission. The information at June 30, 2012 and the results of the Company’s operations for the three and six months ended June 30, 2012 and 2011 are unaudited. The condensed consolidated financial statements reflect all adjustments, consisting of only normal recurring accruals, which are, in the opinion of management, necessary for a fair statement of the results of the interim periods presented. These condensed consolidated financial statements and notes hereto should be read in conjunction with the audited financial statements from which they were derived and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011. The accounting policies used in preparing these condensed consolidated financial statements are the same as those described in the Company’s Form 10-K with the exception of new accounting pronouncements adopted in 2012. The results of operations for the interim periods presented are not necessarily indicative of results to be expected for any other interim period or for the year as a whole.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues, expenses and disclosures of contingent assets and liabilities. Actual results could differ materially from these estimates. Significant estimates include allowance for doubtful accounts receivable, provision for excess and obsolete inventory, valuation of intangible and long-lived assets, valuation of goodwill, litigation, provision for warranty costs, income taxes and share-based compensation expense.

Difficult global economic conditions, tight credit markets, volatile equity, foreign currency and energy markets and declines in consumer spending have combined to increase the uncertainty inherent in these estimates and assumptions. As future events and their effects cannot be determined with precision, particularly those related to the condition of the economy, actual results could differ significantly from these estimates.

New Accounting Pronouncements

In September 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-08 “Intangibles-Goodwill and Other (Topic 350) — Testing Goodwill for Impairment.” ASU 2011-08 amends the previous guidance under Topic 350 which required an entity to test goodwill for impairment, on at least an annual basis, by performing the two-step goodwill impairment test described in Topic 350. The amendments in ASU 2011-08 permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The more likely than not threshold is defined as having likelihood of more than 50 percent. ASU 2011-08 is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. The Company has adopted ASU 2011-08 for our financial statement results beginning January 1, 2012 and there was no material impact on the consolidated financial statements upon adoption.

In June 2011, the FASB issued ASU No. 2011-05 “Comprehensive Income (Topic 220) — Presentation of Comprehensive Income.” ASU 2011-05 requires that all non-owner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. ASU 2011-05 is effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2011. The Company has adopted ASU 2011-05 and for the 2012 interim periods we elected to present comprehensive income (loss) along with our condensed consolidated statements of operations in a single continuous statement.
