Basis of Presentation | Basis of Presentation. The accompanying unaudited condensed consolidated financial statements of Silgan Holdings Inc., or Silgan, have been prepared in accordance with U.S. generally accepted accounting principles, or 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 of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying financial statements include all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation. The results of operations for any interim period are not necessarily indicative of the results of operations for the full year. The Condensed Consolidated Balance Sheet at December 31, 2011 has been derived from our audited consolidated financial statements at that date, but does not include all of the information and footnotes required by GAAP for complete financial statements. You should read the accompanying condensed consolidated financial statements in conjunction with our consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2011. Certain prior years’ amounts have been reclassified to conform with the current year’s presentation.
Goodwill and Other Intangible Assets | Goodwill and Other Intangible Assets. We review goodwill and other indefinite-lived intangible assets for impairment as of July 1 each year and more frequently if circumstances indicate a possible impairment. We determined that our goodwill and other indefinite-lived intangible assets were not impaired in our annual 2012 assessment performed during the third quarter.
Recently Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements. In June 2011, the Financial Accounting Standards Board, or FASB, issued an accounting standards update, or ASU, which amends the guidance for presenting comprehensive income. This amendment required us to present the components of net income and other comprehensive income either as one continuous statement or as two consecutive statements effective January 1, 2012 with retrospective application required. We have elected to present two consecutive statements. Our adoption of this amendment did not have an effect on our financial position, results of operations or cash flows. In July 2012, the FASB issued an ASU which amends the guidance for testing indefinite-lived intangible assets for impairment. This amendment allows us, at our option, to first perform a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired. The result of this qualitative assessment dictates if we need to calculate the fair value of an indefinite-lived intangible asset, compare that value with its carrying amount and record an impairment charge, if any. This amendment is effective for us on January 1, 2013, with early adoption permitted. We adopted this amendment as a part of our annual impairment test performed in the third quarter of 2012. Our adoption of this amendment did not have an effect on our financial position, results of operations or cash flows.
