Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description Of Business And Basis Of Presentation	BUSINESS AND BASIS OF PRESENTATION Business Pilgrim’s Pride Corporation (referred to herein as “Pilgrim’s,” “PPC,” “the Company,” “we,” “us,” “our,” or similar terms) is one of the largest chicken companies in the United States (“US”), Mexico and Puerto Rico. Our fresh chicken retail line is sold in the southeastern, central, southwestern and western regions of the US, throughout Puerto Rico, and in the northern and central regions of Mexico. Our prepared-foods products meet the needs of some of the largest customers in the food service industry across the US. Additionally, the Company exports commodity chicken products to approximately 105 countries. As a vertically integrated company, we control every phase of the production of our products. We operate feed mills, hatcheries, processing plants and distribution centers in 12 US states, Puerto Rico and Mexico. Our fresh chicken products consist of refrigerated (nonfrozen) whole or cut-up chicken, either pre-marinated or non-marinated, and pre-packaged chicken in various combinations of freshly refrigerated, whole chickens and chicken parts. Our prepared chicken products include portion-controlled breast fillets, tenderloins and strips, delicatessen products, salads, formed nuggets and patties and bone-in chicken parts. These products are sold either refrigerated or frozen and may be fully cooked, partially cooked or raw. In addition, these products are breaded or non-breaded and either pre-marinated or non-marinated. Consolidated Financial Statements On December 28, 2009, the Company adopted the Amended and Restated Corporate Bylaws (the “Restated Bylaws”), which changed the Company’s fiscal year end from the Saturday nearest September 30 of each year to the last Sunday in December of each year. This change aligns the Company’s reporting cycle with the fiscal calendar of JBS USA Holdings, Inc. (“JBS USA”). The change was effective with the Company’s 2010 fiscal year, which began December 28, 2009 and ended December 26, 2010 and resulted in an approximate three-month transition period which began September 27, 2009 and ended December 27, 2009 (the “Transition Period”). The Company now operates on the basis of a 52/53-week fiscal year that ends on the Sunday falling on or before December 31. The reader should assume any reference we make to a particular year (for example, 2010) in the notes to these Consolidated Financial Statements applies to our fiscal year and not the calendar year. The consolidated financial statements include the accounts of Pilgrim’s Pride Corporation and its majority owned subsidiaries. We eliminate all significant affiliate accounts and transactions upon consolidation. The Company measures the financial statements of its Mexico subsidiaries as if the US dollar were the functional currency. Accordingly, we remeasure assets and liabilities, other than non-monetary assets, of the Mexico subsidiaries at current exchange rates. We remeasure nonmonetary assets using the historical exchange rate in effect on the date of each asset's acquisition. We remeasure income and expenses at average exchange rates in effect during the period, except for certain accounts which are remeasured at a historical rate. Currency exchange gains or losses are included in the line item Foreign currency transaction losses in the Condensed Consolidated Statements of Operations. Revenue Recognition We recognize revenue when all of the following circumstances are satisfied: (i) persuasive evidence of an arrangement exits, (ii) price is fixed or determinable, (iii) collectability is reasonably assured and (iv) delivery has occurred. Delivery occurs in the period in which the customer takes title and assumes the risks and rewards of ownership of the products specified in the customer's purchase order or sales agreement. Revenue is recorded net of estimated incentive offerings including special pricing agreements, promotions and other volume-based incentives. Revisions to these estimates are charged back to net sales in the period in which the facts that give rise to the revision become known. Shipping and Handling Costs Costs associated with the products shipped to customers are recognized in cost of sales. Cash Equivalents The Company considers highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Current and Long-Term Investments The Company’s current and long-term investments consist primarily of fixed income securities, municipal debt securities, bond and equity mutual funds and fund-of-funds. The fixed income securities, municipal debt securities, bond and equity mutual funds and fund-of-funds are classified as available-for-sale. These securities are recorded at fair value, and unrealized holding gains and losses are recorded, net of tax, as a separate component of accumulated other comprehensive income. Debt securities with remaining maturities of less than one year and those identified by management at the time of purchase for funding operations in less than one year are classified as current. Debt securities with remaining maturities greater than one year that management has not identified at the time of purchase for funding operations in less than one year are classified as long-term. Unrealized losses are charged against net earnings when a decline in fair value is determined to be other than temporary. Management reviews several factors to determine whether a loss is other than temporary, such as the length of time a security is in an unrealized loss position, the extent to which fair value is less than amortized cost, the impact of changing interest rates in the short and long term, and the Company’s intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. The Company determines the cost of each security sold and each amount reclassified out of accumulated other comprehensive income into earnings using the specific identification method. Purchases and sales are recorded on a trade date basis. Investments in joint ventures and entities in which the Company has an ownership interest greater than 50% and exercises control over the venture are consolidated in the Consolidated Financial Statements. Investments in joint ventures and entities in which the Company has an ownership interest between 20% and 50% and exercises significant influence are accounted for using the equity method. The Company invests from time to time in ventures in which its ownership interest is less than 20% and over which it does not exercise significant influence. Such investments are accounted for under the cost method. The fair values for investments not traded on a quoted exchange are estimated based upon the historical performance of the ventures, the ventures’ forecasted financial performance and management’s evaluation of the ventures’ viability and business models. To the extent the book value of an investment exceeds its assessed fair value, the Company will record an appropriate impairment charge. Thus, the carrying value of the Company’s investments approximates fair value. Accounts Receivable The Company records accounts receivable when revenue is recognized. We record an allowance for doubtful accounts, reducing our receivables balance to an amount we estimate is collectible from our customers. Estimates used in determining the allowance for doubtful accounts are based on historical collection experience, current trends, aging of accounts receivable, and periodic credit evaluations of our customers’ financial condition. We write off accounts receivable when it becomes apparent, based upon age or customer circumstances, that such amounts will not be collected. Generally, the Company does not require collateral for its accounts receivable. Inventories Live chicken inventories are stated at the lower of cost or market and breeder hens at the lower of cost, less accumulated amortization, or market. The costs associated with breeder hens are accumulated up to the production stage and amortized over their productive lives using the unit-of-production method. Finished poultry products, feed, eggs and other inventories are stated at the lower of cost (average) or market. We record valuation adjustments for our inventory and for estimated obsolescence at or equal to the difference between the cost of inventory and the estimated market value based upon known conditions affecting inventory, including significantly aged products, discontinued product lines, or damaged or obsolete products. We allocate meat costs between our various finished chicken products based on a by-product costing technique that reduces the cost of the whole bird by estimated yields and amounts to be recovered for certain by-product parts. This primarily includes leg quarters, wings, tenders and offal, which are carried in inventory at the estimated recovery amounts, with the remaining amount being reflected as our breast meat cost. Generally, the Company performs an evaluation of whether any lower of cost or market adjustments are required at the country level based on a number of factors, including: (i) pools of related inventory, (ii) product continuation or discontinuation, (iii) estimated market selling prices and (iv) expected distribution channels. If actual market conditions or other factors are less favorable than those projected by management, additional inventory adjustments may be required. Property, Plant and Equipment Property, plant and equipment are stated at cost, and repair and maintenance costs are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of these assets. Estimated useful lives for building, machinery and equipment are five to 33 years and for automobiles and trucks are three to ten years. The charge to income resulting from amortization of assets recorded under capital leases is included with depreciation expense. The Company records impairment charges on long-lived assets held for use when events and circumstances indicate that the assets may be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. When the above is true, the impairment charge is determined based upon the amount the net book value of the assets exceeds their fair market value. In making these determinations, the Company utilizes certain assumptions, including, but not limited to: (i) future cash flows estimated to be generated by these assets, which are based on additional assumptions such as asset utilization, remaining length of service and estimated salvage values, (ii) estimated fair market value of the assets and (iii) determinations with respect to the lowest level of cash flows relevant to the respective impairment test, generally groupings of related operational facilities. Given the interdependency of the Company’s individual facilities during the production process, which operate as a vertically integrated network, and the fact that the Company does not price transfers of inventory between its vertically integrated facilities at market prices, it evaluates impairment of assets held for use at the country level (i.e., the US and Mexico). Management believes this is the lowest level of identifiable cash flows for its assets that are held for use in production activities. At the present time, the Company’s forecasts indicate that it can recover the carrying value of its assets held for use based on the projected undiscounted cash flows of the operations. A key assumption in management’s forecast is that the Company’s sales volumes will return to historical margins as supply and demand between commodities and chicken and other animal-based proteins become more balanced. However, the exact timing of the return to historical margins is not certain, and if the return to historical margins is delayed, impairment charges could become necessary in the future. The Company records impairment charges on long-lived assets held for sale when the carrying amount of those assets exceeds their fair value less appropriate selling costs. Fair value is based on amounts documented in sales contracts or letters of intent accepted by the Company, amounts included in counteroffers initiated by the Company, or, in the absence of current contract negotiations, amounts determined using a sales comparison approach for real property and amounts determined using a cost approach for personal property. Under the sales comparison approach, sales and asking prices of reasonably comparable properties are considered to develop a range of unit prices within which the current real estate market is operating. Under the cost approach, a current cost to replace the asset new is calculated and then the estimated replacement cost is reduced to reflect the applicable decline in value resulting from physical deterioration, functional obsolescence and economic obsolescence. Appropriate selling costs includes reasonable broker's commissions, costs to produce title documents, filing fees, legal expenses and the like. We estimate appropriate closing costs as 6% of asset fair value. This rate is considered reasonable for our assets held for sale based on historical experience. Identified Intangible Assets Our identified intangible assets consist of assets subject to amortization such as trade names, customer relationships and non-compete agreements. We calculate amortization of those assets that are subject to amortization on a straight-line basis over the estimated useful lives of the related assets. The useful lives range from three to 15 years for trade names and non-compete agreements and 13 years for customer relationships. We review intangible assets subject to amortization for impairment whenever an event or change in circumstances indicates the carrying values of the assets may not be recoverable. We test intangible assets subject to amortization for impairment and estimate their fair values using the same assumptions and techniques we employ on property, plant and equipment. Litigation and Contingent Liabilities The Company is subject to lawsuits, investigations and other claims related to employment, environmental, product and other matters. The Company is required to assess the likelihood of any adverse judgments or outcomes, as well as potential ranges of probable losses, to these matters. The Company estimates the amount of reserves required for these contingencies when losses are determined to be probable and after considerable analysis of each individual issue. With respect to our environmental remediation obligations, the accrual for environmental remediation liabilities is measured on an undiscounted basis. These reserves may change in the future due to changes in the Company’s assumptions, the effectiveness of strategies, or other factors beyond the Company’s control. Accrued Self Insurance Insurance expense for casualty claims and employee-related health care benefits are estimated using historical and current experience and actuarial estimates. Stop-loss coverage is maintained with third-party insurers to limit the Company’s total exposure. Certain categories of claim liabilities are actuarially determined. The assumptions used to arrive at periodic expenses are reviewed regularly by management. However, actual expenses could differ from these estimates and could result in adjustments to be recognized. Income Taxes The provision for income taxes has been determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred income taxes reflect the net tax effect of temporary differences between the book and tax bases of recorded assets and liabilities, net operating losses and tax credit carry forwards. The amount of deferred tax on these temporary differences is determined using the tax rates expected to apply to the period when the asset is realized or the liability is settled, as applicable, based on the tax rates and laws in the respective tax jurisdiction enacted as of the balance sheet date. The Company reviews its deferred tax assets for recoverability and establishes a valuation allowance based on historical taxable income, potential for carry back of tax losses, projected future taxable income, applicable tax strategies, and the expected timing of the reversals of existing temporary differences. A valuation allowance is provided when it is more likely than not that some or all of the deferred tax assets will not be realized. Valuation allowances have been established primarily for net operating loss carry forwards. See “Note 13. Income Taxes” to the Consolidated Financial Statements. The Company deems its earnings from Mexico to be permanently reinvested. As such, US deferred income taxes have not been provided on these earnings. If such earnings were not considered indefinitely reinvested, certain deferred foreign and US income taxes would be provided. For activity after 2008, the Company did not permanently reinvest its earnings in Puerto Rico. Therefore, net earnings generated in Puerto Rico have US taxes provided as if the earnings were distributed. The Company follows the provisions under ASC 740-10-25 that provides a recognition threshold and measurement criteria for the financial statement recognition of a tax benefit taken or expected to be taken in a tax return. Tax benefits are recognized only when it is more likely than not, based on the technical merits, that the benefits will be sustained on examination. Tax benefits that meet the more-likely-than-not recognition threshold are measured using a probability weighting of the largest amount of tax benefit that has greater than 50% likelihood of being realized upon settlement. Whether the more-likely-than-not recognition threshold is met for a particular tax benefit is a matter of judgment based on the individual facts and circumstances evaluated in light of all available evidence as of the balance sheet date. See “Note 13. Income Taxes” to the Consolidated Financial Statements. Pension and Other Postemployment Benefits Our pension and other postemployment benefit costs and obligations are dependent on the various actuarial assumptions used in calculating such amounts. These assumptions relate to discount rates, salary growth, long-term return on plan assets, health care cost trend rates and other factors. We base the discount rate assumptions on current investment yields on high-quality corporate long-term bonds. The salary growth assumptions reflect our long-term actual experience and future or near-term outlook. We determine the long-term return on plan assets based on historical portfolio results and management’s expectation of the future economic environment. Our health care cost trend assumptions are developed based on historical cost data, the near-term outlook and an assessment of likely long-term trends. Actual results that differ from our assumptions are accumulated and, if in excess of the lesser of 10% of the projected benefit obligation or the fair market value of plan assets, amortized over the estimated future working life of the plan participants. Operating Leases Rent expense for operating leases is recorded on a straight-line basis over the lease term unless the lease contains an escalation clause which is not fixed or determinable. The lease term begins when we have the right to control the use of the leased property, which is typically before rent payments are due under the terms of the lease. If a lease has a fixed or determinable escalation clause, the difference between rent expense and rent paid is recorded as deferred rent and is included in the Consolidated Balance Sheets. Rent for operating leases that do not have an escalation clause or where escalation is based on an inflation index is expensed over the lease term as it is payable. Commodity Risk Management The Company attempts to mitigate commodity purchase exposures through a program of risk management that includes the use of forward purchase contractual obligations and derivative financial instruments. We recognize all derivative financial instruments in the Consolidated Balance Sheets at fair value. We elected not to designate derivative financial instruments executed to mitigate commodity purchase exposures as hedges of forecasted transactions. Therefore, we recognize changes in the fair value of these derivative financial instruments immediately in earnings. Gains or losses related to these derivative financial instruments are included in the line item Cost of sales in the Consolidated Statements of Operations. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the US ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. We make significant estimates in regard to receivables collectability; inventory valuation; realization of deferred tax assets; valuation of long-lived assets; valuation of contingent liabilities, liabilities subject to compromise and self insurance liabilities; valuation of pension and other postretirement benefits obligations; and valuation of acquired businesses. Recently Adopted Accounting Pronouncements On December 27, 2010, the Company adopted a portion of Accounting Standards Update (“ASU”) 2010-06, Improving Disclosures about Fair Value Measurements, issued by the Financial Accounting Standards Board (the "FASB"). The ASU amended Accounting Standards Codification (“ASC”) Subtopic 820-10 by including new required disclosures regarding activity in Level 3 fair value measurements. The adoption of the subject guidance under amended ASC 820-10 did not have a material impact on the Company's consolidated financial statements. Accounting Pronouncements Issued But Not Yet Adopted The FASB recently issued ASU No. 2011-04, Fair Value Measurement: Amendments to Achieve Common Fair Value Disclosure Requirements in the U.S. GAAP and IFRS. The amendment clarifies the FASB's intent about the application of existing fair value measurement and disclosure requirements (ASC Topic 820) and improves consistency in wording to ensure that U.S. GAAP and International Financial Reporting Standards ("IFRS") are described the same way. Other amendments change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements. The amendment is effective for fiscal years beginning after December 15, 2011 and is to be applied prospectively. The Company has not yet adopted this amendment; however, adoption will not have a material impact on the Company's financial position, results of operations or cash flow.

BUSINESS AND BASIS OF PRESENTATION

Business

Pilgrim’s Pride Corporation (referred to herein as “Pilgrim’s,” “PPC,” “the Company,” “we,” “us,” “our,” or similar terms) is one of the largest chicken companies in the United States (“US”), Mexico and Puerto Rico. Our fresh chicken retail line is sold in the southeastern, central, southwestern and western regions of the US, throughout Puerto Rico, and in the northern and central regions of Mexico. Our prepared-foods products meet the needs of some of the largest customers in the food service industry across the US. Additionally, the Company exports commodity chicken products to approximately 105 countries. As a vertically integrated company, we control every phase of the production of our products. We operate feed mills, hatcheries, processing plants and distribution centers in 12 US states, Puerto Rico and Mexico. Our fresh chicken products consist of refrigerated (nonfrozen) whole or cut-up chicken, either pre-marinated or non-marinated, and pre-packaged chicken in various combinations of freshly refrigerated, whole chickens and chicken parts. Our prepared chicken products include portion-controlled breast fillets, tenderloins and strips, delicatessen products, salads, formed nuggets and patties and bone-in chicken parts. These products are sold either refrigerated or frozen and may be fully cooked, partially cooked or raw. In addition, these products are breaded or non-breaded and either pre-marinated or non-marinated.

Consolidated Financial Statements

On December 28, 2009, the Company adopted the Amended and Restated Corporate Bylaws (the “Restated Bylaws”), which changed the Company’s fiscal year end from the Saturday nearest September 30 of each year to the last Sunday in December of each year. This change aligns the Company’s reporting cycle with the fiscal calendar of JBS USA Holdings, Inc. (“JBS USA”). The change was effective with the Company’s 2010 fiscal year, which began December 28, 2009 and ended December 26, 2010 and resulted in an approximate three-month transition period which began September 27, 2009 and ended December 27, 2009 (the “Transition Period”). The Company now operates on the basis of a 52/53-week fiscal year that ends on the Sunday falling on or before December 31. The reader should assume any reference we make to a particular year (for example, 2010) in the notes to these Consolidated Financial Statements applies to our fiscal year and not the calendar year.

The consolidated financial statements include the accounts of Pilgrim’s Pride Corporation and its majority owned subsidiaries. We eliminate all significant affiliate accounts and transactions upon consolidation.

The Company measures the financial statements of its Mexico subsidiaries as if the US dollar were the functional currency. Accordingly, we remeasure assets and liabilities, other than non-monetary assets, of the Mexico subsidiaries at current exchange rates. We remeasure nonmonetary assets using the historical exchange rate in effect on the date of each asset's acquisition. We remeasure income and expenses at average exchange rates in effect during the period, except for certain accounts which are remeasured at a historical rate. Currency exchange gains or losses are included in the line item Foreign currency transaction losses in the Condensed Consolidated Statements of Operations.

Revenue Recognition

We recognize revenue when all of the following circumstances are satisfied: (i) persuasive evidence of an arrangement exits, (ii) price is fixed or determinable, (iii) collectability is reasonably assured and (iv) delivery has occurred. Delivery occurs in the period in which the customer takes title and assumes the risks and rewards of ownership of the products specified in the customer's purchase order or sales agreement. Revenue is recorded net of estimated incentive offerings including special pricing agreements, promotions and other volume-based incentives. Revisions to these estimates are charged back to net sales in the period in which the facts that give rise to the revision become known.

Shipping and Handling Costs

Costs associated with the products shipped to customers are recognized in cost of sales.

Cash Equivalents

The Company considers highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

Current and Long-Term Investments

The Company’s current and long-term investments consist primarily of fixed income securities, municipal debt securities, bond and equity mutual funds and fund-of-funds. The fixed income securities, municipal debt securities, bond and equity mutual funds and fund-of-funds are classified as available-for-sale. These securities are recorded at fair value, and unrealized holding gains and losses are recorded, net of tax, as a separate component of accumulated other comprehensive income. Debt securities with remaining maturities of less than one year and those identified by management at the time of purchase for funding operations in less than one year are classified as current. Debt securities with remaining maturities greater than one year that management has not identified at the time of purchase for funding operations in less than one year are classified as long-term. Unrealized losses are charged against net earnings when a decline in fair value is determined to be other than temporary. Management reviews several factors to determine whether a loss is other than temporary, such as the length of time a security is in an unrealized loss position, the extent to which fair value is less than amortized cost, the impact of changing interest rates in the short and long term, and the Company’s intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. The Company determines the cost of each security sold and each amount reclassified out of accumulated other comprehensive income into earnings using the specific identification method. Purchases and sales are recorded on a trade date basis.

Investments in joint ventures and entities in which the Company has an ownership interest greater than 50% and exercises control over the venture are consolidated in the Consolidated Financial Statements. Investments in joint ventures and entities in which the Company has an ownership interest between 20% and 50% and exercises significant influence are accounted for using the equity method. The Company invests from time to time in ventures in which its ownership interest is less than 20% and over which it does not exercise significant influence. Such investments are accounted for under the cost method. The fair values for investments not traded on a quoted exchange are estimated based upon the historical performance of the ventures, the ventures’ forecasted financial performance and management’s evaluation of the ventures’ viability and business models. To the extent the book value of an investment exceeds its assessed fair value, the Company will record an appropriate impairment charge. Thus, the carrying value of the Company’s investments approximates fair value.

Accounts Receivable

The Company records accounts receivable when revenue is recognized. We record an allowance for doubtful accounts, reducing our receivables balance to an amount we estimate is collectible from our customers. Estimates used in determining the allowance for doubtful accounts are based on historical collection experience, current trends, aging of accounts receivable, and periodic credit evaluations of our customers’ financial condition. We write off accounts receivable when it becomes apparent, based upon age or customer circumstances, that such amounts will not be collected. Generally, the Company does not require collateral for its accounts receivable.

Inventories

Live chicken inventories are stated at the lower of cost or market and breeder hens at the lower of cost, less accumulated amortization, or market. The costs associated with breeder hens are accumulated up to the production stage and amortized over their productive lives using the unit-of-production method. Finished poultry products, feed, eggs and other inventories are stated at the lower of cost (average) or market.

We record valuation adjustments for our inventory and for estimated obsolescence at or equal to the difference between the cost of inventory and the estimated market value based upon known conditions affecting inventory, including significantly aged products, discontinued product lines, or damaged or obsolete products. We allocate meat costs between our various finished chicken products based on a by-product costing technique that reduces the cost of the whole bird by estimated yields and amounts to be recovered for certain by-product parts. This primarily includes leg quarters, wings, tenders and offal, which are carried in inventory at the estimated recovery amounts, with the remaining amount being reflected as our breast meat cost.

Generally, the Company performs an evaluation of whether any lower of cost or market adjustments are required at the country level based on a number of factors, including: (i) pools of related inventory, (ii) product continuation or discontinuation, (iii) estimated market selling prices and (iv) expected distribution channels. If actual market conditions or other factors are less favorable than those projected by management, additional inventory adjustments may be required.

Property, Plant and Equipment

Property, plant and equipment are stated at cost, and repair and maintenance costs are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of these assets. Estimated useful lives for building, machinery and equipment are five to 33 years and for automobiles and trucks are three to ten years. The charge to income resulting from amortization of assets recorded under capital leases is included with depreciation expense.

The Company records impairment charges on long-lived assets held for use when events and circumstances indicate that the assets may be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. When the above is true, the impairment charge is determined based upon the amount the net book value of the assets exceeds their fair market value. In making these determinations, the Company utilizes certain assumptions, including, but not limited to: (i) future cash flows estimated to be generated by these assets, which are based on additional assumptions such as asset utilization, remaining length of service and estimated salvage values, (ii) estimated fair market value of the assets and (iii) determinations with respect to the lowest level of cash flows relevant to the respective impairment test, generally groupings of related operational facilities.

Given the interdependency of the Company’s individual facilities during the production process, which operate as a vertically integrated network, and the fact that the Company does not price transfers of inventory between its vertically integrated facilities at market prices, it evaluates impairment of assets held for use at the country level (i.e., the US and Mexico). Management believes this is the lowest level of identifiable cash flows for its assets that are held for use in production activities. At the present time, the Company’s forecasts indicate that it can recover the carrying value of its assets held for use based on the projected undiscounted cash flows of the operations. A key assumption in management’s forecast is that the Company’s sales volumes will return to historical margins as supply and demand between commodities and chicken and other animal-based proteins become more balanced. However, the exact timing of the return to historical margins is not certain, and if the return to historical margins is delayed, impairment charges could become necessary in the future.

The Company records impairment charges on long-lived assets held for sale when the carrying amount of those assets exceeds their fair value less appropriate selling costs. Fair value is based on amounts documented in sales contracts or letters of intent accepted by the Company, amounts included in counteroffers initiated by the Company, or, in the absence of current contract negotiations, amounts determined using a sales comparison approach for real property and amounts determined using a cost approach for personal property. Under the sales comparison approach, sales and asking prices of reasonably comparable properties are considered to develop a range of unit prices within which the current real estate market is operating. Under the cost approach, a current cost to replace the asset new is calculated and then the estimated replacement cost is reduced to reflect the applicable decline in value resulting from physical deterioration, functional obsolescence and economic obsolescence. Appropriate selling costs includes reasonable broker's commissions, costs to produce title documents, filing fees, legal expenses and the like. We estimate appropriate closing costs as 6% of asset fair value. This rate is considered reasonable for our assets held for sale based on historical experience.

Identified Intangible Assets

Our identified intangible assets consist of assets subject to amortization such as trade names, customer relationships and non-compete agreements. We calculate amortization of those assets that are subject to amortization on a straight-line basis over the estimated useful lives of the related assets. The useful lives range from three to 15 years for trade names and non-compete agreements and 13 years for customer relationships.

We review intangible assets subject to amortization for impairment whenever an event or change in circumstances indicates the carrying values of the assets may not be recoverable. We test intangible assets subject to amortization for impairment and estimate their fair values using the same assumptions and techniques we employ on property, plant and equipment.

Litigation and Contingent Liabilities

The Company is subject to lawsuits, investigations and other claims related to employment, environmental, product and other matters. The Company is required to assess the likelihood of any adverse judgments or outcomes, as well as potential ranges of probable losses, to these matters. The Company estimates the amount of reserves required for these contingencies when losses are determined to be probable and after considerable analysis of each individual issue. With respect to our environmental remediation obligations, the accrual for environmental remediation liabilities is measured on an undiscounted basis. These reserves may change in the future due to changes in the Company’s assumptions, the effectiveness of strategies, or other factors beyond the Company’s control.

Accrued Self Insurance

Insurance expense for casualty claims and employee-related health care benefits are estimated using historical and current experience and actuarial estimates. Stop-loss coverage is maintained with third-party insurers to limit the Company’s total exposure. Certain categories of claim liabilities are actuarially determined. The assumptions used to arrive at periodic expenses are reviewed regularly by management. However, actual expenses could differ from these estimates and could result in adjustments to be recognized.

Income Taxes

The provision for income taxes has been determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred income taxes reflect the net tax effect of temporary differences between the book and tax bases of recorded assets and liabilities, net operating losses and tax credit carry forwards. The amount of deferred tax on these temporary differences is determined using the tax rates expected to apply to the period when the asset is realized or the liability is settled, as applicable, based on the tax rates and laws in the respective tax jurisdiction enacted as of the balance sheet date.

The Company reviews its deferred tax assets for recoverability and establishes a valuation allowance based on historical taxable income, potential for carry back of tax losses, projected future taxable income, applicable tax strategies, and the expected timing of the reversals of existing temporary differences. A valuation allowance is provided when it is more likely than not that some or all of the deferred tax assets will not be realized. Valuation allowances have been established primarily for net operating loss carry forwards. See “Note 13. Income Taxes” to the Consolidated Financial Statements.

The Company deems its earnings from Mexico to be permanently reinvested. As such, US deferred income taxes have not been provided on these earnings. If such earnings were not considered indefinitely reinvested, certain deferred foreign and US income taxes would be provided. For activity after 2008, the Company did not permanently reinvest its earnings in Puerto Rico. Therefore, net earnings generated in Puerto Rico have US taxes provided as if the earnings were distributed.

The Company follows the provisions under ASC 740-10-25 that provides a recognition threshold and measurement criteria for the financial statement recognition of a tax benefit taken or expected to be taken in a tax return. Tax benefits are recognized only when it is more likely than not, based on the technical merits, that the benefits will be sustained on examination. Tax benefits that meet the more-likely-than-not recognition threshold are measured using a probability weighting of the largest amount of tax benefit that has greater than 50% likelihood of being realized upon settlement. Whether the more-likely-than-not recognition threshold is met for a particular tax benefit is a matter of judgment based on the individual facts and circumstances evaluated in light of all available evidence as of the balance sheet date. See “Note 13. Income Taxes” to the Consolidated Financial Statements.

Pension and Other Postemployment Benefits

Our pension and other postemployment benefit costs and obligations are dependent on the various actuarial assumptions used in calculating such amounts. These assumptions relate to discount rates, salary growth, long-term return on plan assets, health care cost trend rates and other factors. We base the discount rate assumptions on current investment yields on high-quality corporate long-term bonds. The salary growth assumptions reflect our long-term actual experience and future or near-term outlook. We determine the long-term return on plan assets based on historical portfolio results and management’s expectation of the future economic environment. Our health care cost trend assumptions are developed based on historical cost data, the near-term outlook and an assessment of likely long-term trends. Actual results that differ from our assumptions are accumulated and, if in excess of the lesser of 10% of the projected benefit obligation or the fair market value of plan assets, amortized over the estimated future working life of the plan participants.

Operating Leases

Rent expense for operating leases is recorded on a straight-line basis over the lease term unless the lease contains an escalation clause which is not fixed or determinable. The lease term begins when we have the right to control the use of the leased property, which is typically before rent payments are due under the terms of the lease. If a lease has a fixed or determinable escalation clause, the difference between rent expense and rent paid is recorded as deferred rent and is included in the Consolidated Balance Sheets. Rent for operating leases that do not have an escalation clause or where escalation is based on an inflation index is expensed over the lease term as it is payable.

Commodity Risk Management

The Company attempts to mitigate commodity purchase exposures through a program of risk management that includes the use of forward purchase contractual obligations and derivative financial instruments. We recognize all derivative financial instruments in the Consolidated Balance Sheets at fair value. We elected not to designate derivative financial instruments executed to mitigate commodity purchase exposures as hedges of forecasted transactions. Therefore, we recognize changes in the fair value of these derivative financial instruments immediately in earnings. Gains or losses related to these derivative financial instruments are included in the line item Cost of sales in the Consolidated Statements of Operations.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the US ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. We make significant estimates in regard to receivables collectability; inventory valuation; realization of deferred tax assets; valuation of long-lived assets; valuation of contingent liabilities, liabilities subject to compromise and self insurance liabilities; valuation of pension and other postretirement benefits obligations; and valuation of acquired businesses.

Recently Adopted Accounting Pronouncements

On December 27, 2010, the Company adopted a portion of Accounting Standards Update (“ASU”) 2010-06, Improving Disclosures about Fair Value Measurements, issued by the Financial Accounting Standards Board (the "FASB"). The ASU amended Accounting Standards Codification (“ASC”) Subtopic 820-10 by including new required disclosures regarding activity in Level 3 fair value measurements. The adoption of the subject guidance under amended ASC 820-10 did not have a material impact on the Company's consolidated financial statements.

Accounting Pronouncements Issued But Not Yet Adopted

The FASB recently issued ASU No. 2011-04, Fair Value Measurement: Amendments to Achieve Common Fair Value Disclosure Requirements in the U.S. GAAP and IFRS. The amendment clarifies the FASB's intent about the application of existing fair value measurement and disclosure requirements (ASC Topic 820) and improves consistency in wording to ensure that U.S. GAAP and International Financial Reporting Standards ("IFRS") are described the same way. Other amendments change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements. The amendment is effective for fiscal years beginning after December 15, 2011 and is to be applied prospectively. The Company has not yet adopted this amendment; however, adoption will not have a material impact on the Company's financial position, results of operations or cash flow.
