Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The consolidated financial statements include the accounts of Darling and its consolidated subsidiaries. Noncontrolling interests represents the outstanding ownership interest in the Company's consolidated subsidiaries that are not owned by the Company. In the accompanying Consolidated Statements of Operations, the noncontrolling interest in net income (loss) of the consolidated subsidiaries is shown as an allocation of the Company's net income and is presented separately as "Net income/(loss) attributable to noncontrolling interests". In the Company's Consolidated Balance Sheets, noncontrolling interests represents the ownership interests in the Company consolidated subsidiaries' net assets held by parties other than the Company. These ownership interests are presented separately as "Noncontrolling interests" within "Stockholders' Equity." All significant intercompany balances and transactions have been eliminated in consolidation.
Fiscal Periods | Fiscal Periods The Company has a 52/53 week fiscal year ending on the Saturday nearest December 31. Fiscal periods for the consolidated financial statements included herein are as of April 4, 2015, and include the 13 weeks ended April 4, 2015, and the 13 weeks ended March 29, 2014.
Reclassifications | Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation.
Earnings Per Share | Earnings Per Share Basic income/(loss) per common share is computed by dividing net income attributable to Darling by the weighted average number of common shares including non-vested and restricted shares outstanding during the period. Diluted income/(loss) per common share is computed by dividing net income attributable to Darling by the weighted average number of common shares outstanding during the period increased by dilutive common equivalent shares determined using the treasury stock method.
Revenue Recognition | Revenue Recognition The Company recognizes revenue on sales when products are shipped and the customer takes ownership and assumes risk of loss. Certain customers may be required to prepay prior to shipment in order to maintain payment protection related to certain foreign and domestic sales. These amounts are recorded as unearned revenue and recognized when the products have shipped and the customer takes ownership and assumes risk of loss. The Company has formula arrangements with certain suppliers whereby the charge or credit for raw materials is tied to published finished product commodity prices after deducting a fixed processing fee incorporated into the formula and is recorded as a cost of sale by line of business. The Company recognizes service revenue in the fiscal month the service occurs.
Income Taxes | The Company accounts for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company expects to indefinitely reinvest the earnings of its foreign subsidiaries outside of the United States and has generally not provided deferred income taxes on the accumulated earnings of its foreign subsidiaries. The Company periodically assesses whether it is more likely than not that it will generate sufficient taxable income to realize its deferred income tax assets. In making this determination, the Company considers all available positive and negative evidence and makes certain assumptions. The Company considers, among other things, its deferred tax liabilities, the overall business environment, its historical earnings and losses, current industry trends and its outlook for future years. Certain VION Companies acquired as part of the VION Acquisition have deferred tax assets for tax loss carryforwards, and the Company has recorded valuation allowances in respect to those losses to the extent it has been determined that it is not more likely than not that the deferred tax assets will be realized.
Foreign Currency Transactions and Translations Policy [Policy Text Block] | Foreign Currency Translation and Remeasurement Foreign currency translation is included as a component of accumulated other comprehensive income and reflects the adjustments resulting from translating the foreign currency denominated financial statements of foreign subsidiaries into U.S. dollars. The functional currency of the Company's foreign subsidiaries is the currency of the primary economic environment in which the entity operates, which is generally the local currency of the country. Accordingly, assets and liabilities of the foreign subsidiaries are translated to U.S. dollars at fiscal period end exchange rates, including intercompany foreign currency transactions that are of long-term investment nature. Income and expense items are translated at average exchange rates occurring during the period. Changes in exchange rates that affect cash flows and the related receivables or payables are recognized as transaction gains and losses in determining net income.
Long Lived Assets [Policy Text Block] | Long-Lived Assets Property, Plant and Equipment Property, plant and equipment are recorded at cost. Depreciation is computed by the straight-line method over the estimated useful lives of assets: 1) Buildings and improvements, 15 to 30 years; 2) Machinery and equipment, 3 to 10 years; 3) Vehicles, 3 to 8 years; and 4) Aircraft, 7 to 10 years. Maintenance and repairs are charged to expense as incurred and expenditures for major renewals and improvements are capitalized. Intangible Assets Intangible assets with indefinite lives, and therefore, not subject to amortization, consist of trade names acquired in the acquisition of Griffin Industries Inc. on December 17, 2010 (which was subsequently converted to a limited liability company) and its subsidiaries ("Griffin") and trade names acquired in the VION Acquisition. In the first quarter of fiscal 2015, the Company has determined that due to a global re-branding strategy, the Griffin Industries trade name in the amount of approximately $65.1 million has been determined to have a limited useful life and therefore the Company has started to amortize the Griffin Industries name over a useful life of 10 years. Intangible assets subject to amortization consist of: 1) collection routes which are made up of groups of suppliers of raw materials in similar geographic areas from which the Company derives collection fees and a dependable source of raw materials for processing into finished products; 2) permits that represent licensing of operating plants that have been acquired, giving those plants the ability to operate; 3) non-compete agreements that represent contractual arrangements with former competitors whose businesses were acquired; 4) trade names; and 5) royalty, consulting, land use rights and leasehold agreements. Amortization expense is calculated using the straight-line method over the estimated useful lives of the assets ranging from: 5 to 21 years for collection routes; 10 to 20 years for permits; 3 to 7 years for non-compete covenants; and 4 to 15 years for trade names. Royalty, consulting, land use rights and leasehold agreements are amortized over the term of the agreement.
