Summary of Significant Accounting Policies (Policies)	12 Months Ended
Dec. 31, 2012
Nature of Business	Nature of Business. Silgan Holdings Inc., or Silgan, and its subsidiaries conduct business in three market segments: metal containers, closures and plastic containers. Our metal container business is engaged in the manufacture and sale of steel and aluminum containers for human and pet food and general line products. Our closures business manufactures and sells metal, composite and plastic vacuum closures for food and beverage products and plastic closures for the dairy and juice markets. Our plastic container business manufactures and sells custom designed plastic containers, tubes and closures for personal care, food, health care, pharmaceutical, household and industrial chemical, pet care, agricultural chemical, automotive and marine chemical products. Our metal container business has operating facilities in North America, Europe and Asia. Our closures business has operating facilities in North and South America, Europe and Asia. Our plastic container business is based in North America.
Basis of Presentation	Basis of Presentation. The consolidated financial statements include the accounts of Silgan and our subsidiaries. Newly acquired subsidiaries have been included in the consolidated financial statements from their dates of acquisition. All significant intercompany transactions have been eliminated. The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles, or GAAP, requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates.
Foreign Currency Transactions and Translations Policy	Generally, our subsidiaries that operate outside the United States use their local currency as the functional currency. The principal functional currencies for our foreign operations are the Euro and the Canadian dollar. Balance sheet accounts of our foreign subsidiaries are translated at exchange rates in effect at the balance sheet date, while revenue and expense accounts are translated at average rates prevailing during the year. Translation adjustments are reported as a component of accumulated other comprehensive (loss) income. Gains or losses resulting from transactions denominated in foreign currencies that are not designated as a hedge are included in selling, general and administrative expenses in our Consolidated Statements of Income.
Stock Split	Stock Split. On March 29, 2010, our Board of Directors declared a two-for-one stock split of our issued common stock. The stock split was effected on May 3, 2010 in the form of a stock dividend. Stockholders of record at the close of business on April 20, 2010 were issued one additional share of common stock for each share of common stock held by them on that date. Stockholders’ equity reflects the stock split in 2010 by reclassifying from paid-in capital to common stock an amount equal to the par value of the additional shares issued as a result of the stock split.
Cash and Cash Equivalents	Cash and Cash Equivalents. Cash equivalents represent short-term, highly liquid investments which are readily convertible to cash and have maturities of three months or less at the time of purchase. As a result of our cash management system, checks issued for payment may create negative book balances. Checks outstanding in excess of related book balances are included in trade accounts payable in our Consolidated Balance Sheets. Changes in outstanding checks are included in financing activities in our Consolidated Statements of Cash Flows to treat them as, in substance, cash advances.
Inventories	Inventories. Inventories are valued at the lower of cost or market (net realizable value). Cost for domestic inventories for our metal container and closures businesses is principally determined on the last-in, first-out basis, or LIFO. Cost for inventories for our plastic container business is principally determined on the first-in, first-out basis, or FIFO. Cost for foreign inventories for our metal container and closures businesses is principally determined on the average cost method.
Property, Plant and Equipment, Net	Property, Plant and Equipment, Net. Property, plant and equipment, net is stated at historical cost less accumulated depreciation. Major renewals and betterments that extend the life of an asset are capitalized and repairs and maintenance expenditures are charged to expense as incurred. Design and development costs for molds, dies and other tools that we do not own and that will be used to produce products that will be sold under long-term supply arrangements are capitalized. Depreciation is computed using the straight-line method over the estimated useful lives of depreciable assets. The principal estimated useful lives are 35 years for buildings and range between 3 to 18 years for machinery and equipment. Leasehold improvements are amortized over the shorter of the life of the related asset or the life of the lease. Interest incurred on amounts borrowed in connection with the installation of major machinery and equipment acquisitions is capitalized. Capitalized interest of $0.3 million, $0.7 million and $0.8 million in 2012, 2011 and 2010, respectively, was recorded as part of the cost of the assets to which it relates and is amortized over the assets’ estimated useful life.
Goodwill and Other Intangible Assets, Net	Goodwill and Other Intangible Assets, Net. Our reporting units are the same as our business segments. We review goodwill and other indefinite-lived intangible assets for impairment as of July 1 of each year and more frequently if circumstances indicate a possible impairment. We determined that goodwill and other indefinite-lived intangible assets were not impaired in our annual assessment performed during the third quarter. See Note 7 for further information.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets. We assess long-lived assets, including intangible assets with definite lives, for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be fully recoverable. An impairment exists if the estimate of future undiscounted cash flows generated by the assets is less than the carrying value of the assets. If impairment is determined to exist, any related impairment loss is then measured by comparing the fair value of the assets to their carrying amount.
Hedging Instruments	Hedging Instruments. All derivative financial instruments are recorded in the Consolidated Balance Sheets at their fair values. Changes in fair values of derivatives are recorded in each period in earnings or comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and, if it is, the type of hedge transaction. We utilize certain derivative financial instruments to manage a portion of our interest rate and natural gas cost exposures. We do not engage in trading or other speculative uses of these financial instruments. For a financial instrument to qualify as a hedge, we must be exposed to interest rate or price risk, and the financial instrument must reduce the exposure and be designated as a hedge. Financial instruments qualifying for hedge accounting must maintain a high correlation between the hedging instrument and the item being hedged, both at inception and throughout the hedged period. We utilize certain internal hedging strategies to minimize our foreign currency exchange rate risk. Net investment hedges that qualify for hedge accounting result in the recognition of foreign currency gains or losses, net of tax, in accumulated other comprehensive (loss) income. We generally do not utilize external derivative financial instruments to manage our foreign currency exchange rate risk.
Income Taxes	Income Taxes. We account for income taxes using the liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period of enactment of such change. No provision is made for U.S. income taxes applicable to undistributed earnings of foreign subsidiaries that are indefinitely reinvested.
Revenue Recognition	Revenue Recognition. Revenues are recognized when goods are shipped and the title and risk of loss pass to the customer. For those sites where we operate within the customer’s facilities, title and risk of loss pass to the customer upon delivery of product to clearly delineated areas within the common facility, at which time we recognize revenues. Shipping and handling fees and costs incurred in connection with products sold are recorded in cost of goods sold in our Consolidated Statements of Income.
Stock-Based Compensation	Stock-Based Compensation. We currently have one stock-based compensation plan in effect, which plan replaced two previous plans. Under our current stock-based compensation plan, we have issued stock options and restricted stock units to our officers, other key employees and outside directors. A restricted stock unit represents the right to receive one share of our common stock at a future date. Unvested restricted stock units that have been issued do not have voting rights and may not be disposed of or transferred during the vesting period.
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.
Recently Issued Accounting Pronouncement	Recently Issued Accounting Pronouncement. In February 2013, the FASB issued an ASU which amends the guidance for reporting reclassification adjustments from accumulated other comprehensive income to net income. This amendment will require us to present information that is significant about reclassification adjustments from accumulated other comprehensive income to net income in one footnote and, in some cases, cross-references to related footnote disclosures. This amendment is effective for us on January 1, 2013. We are currently evaluating the disclosure implications of this amendment, however the adoption of it will not have an effect on our financial position, results of operations or cash flows.
