1. BASIS OF PRESENTATION

The accompanying interim unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the unaudited condensed consolidated financial statements have been prepared on the same basis as the prior year audited financial statements and all adjustments considered necessary for a fair presentation have been included in the financial statements. All such adjustments are of a normal recurring nature. The results for the interim period are not necessarily indicative of the results to be expected for any future period or for the fiscal year ending December 31, 2018.

The Condensed Consolidated Balance Sheet at December 31, 2017 has been derived from the audited financial statements at that date, but does not include all the information and footnotes required by U.S. GAAP for complete financial statements.

On June 29, 2018 (the “Distribution Date”), Autoliv completed the spin-off of its former Electronics segment (the “spin-off”) through the distribution of all of the issued and outstanding stock of Veoneer, Inc. (“Veoneer”). To effect the spin-off, Autoliv distributed to each Autoliv stockholder one share of Veoneer common stock, par value $1.00 per share, for every one share of Autoliv common stock, par value $1.00 per share, held by such person on the common stock record date, and each Autoliv Swedish Depository Receipt (SDR) holder received one Veoneer SDR for each Autoliv SDR held by such person on the applicable SDR record date. On July 2, 2018, Veoneer’s common stock began regular-way trading on the New York Stock Exchange under the symbol “VNE” and its SDRs began trading on Nasdaq Stockholm under the symbol “VNE SDB.” The Company did not retain any equity interest in Veoneer.

In accordance with U.S. GAAP, the financial position and results of operations of the Electronics business are presented as discontinued operations and, as such, have been excluded from continuing operations for all periods presented. The restated historical financial statements reflecting the spin-off are unaudited, but have been derived from Autoliv’s historical audited annual reports. The sum of the individual earnings per share amounts from continuing operations and discontinued operations may not equal the total company earnings per share amounts due to rounding. The cash flows and comprehensive income related to the Electronics business have not been segregated and are included in the Condensed Consolidated Statements of Cash Flows and Comprehensive Income, respectively, for all periods presented. With the exception of Note 3, the Notes to the Unaudited Condensed Consolidated Financial Statements reflect the continuing operations of Autoliv. See Note 3 - Discontinued Operations below for additional information regarding discontinued operations.

On April 1, 2018, in preparation for the spin-off, pursuant to the terms of a master transfer agreement entered into between Autoliv and Veoneer, assets related to the Electronics business were transferred to, and liabilities related to the Electronics business were retained or assumed by Veoneer, however, responsibility for certain product, warranty and recall liabilities for Electronics products manufactured prior to April 1, 2018 was retained by Autoliv as provided in the Distribution Agreement between Autoliv and Veoneer.

Certain amounts in the prior year’s condensed consolidated financial statements and related footnotes thereto have been reclassified to conform with the current year presentation as a result of the spin-off of Veoneer.

Upon completion of the spin-off, Autoliv has concluded at June 30, 2018 that it has one reportable segment, based on the way the Company evaluates its financial performance and manages its operations. Prior to the completion of the spin-off, the Company had two reportable segments, Electronics and Passive Safety. The Company’s Passive Safety reportable segment includes the Company’s airbag and seatbelt products and components.

Statements in this report that are not of historical fact are forward-looking statements that involve risks and uncertainties that could affect the actual results of the Company. A description of the important factors that could cause Autoliv’s actual results to differ materially from the forward-looking statements contained in this report may be found in this report and Autoliv’s other reports filed with the Securities and Exchange Commission (the “SEC”). For further information, refer to the consolidated financial statements, footnotes and definitions thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, filed with the SEC on February 22, 2018.
