Accounting Policies [Abstract]
New Accounting Standards	NEW ACCOUNTING STANDARDS Accounting Standards Adopted In April 2015 the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-04, "Compensation—Retirement Benefits (Topic 715) Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Assets" (ASU 2015-04). The amendments in ASU 2015-04 allow a reporting entity that may incur more costs than other entities when measuring the fair value of plan assets of a defined benefit pension or other postretirement benefit plan at other than a month-end to measure defined benefit plan assets and obligations using the month-end date that is closest to the date of event (such as a plan amendment, settlement, or curtailment that calls for a remeasurement in accordance with existing requirements) that is triggering the remeasurement. In addition, if a contribution or significant event occurs between the month-end date used to measure defined benefit plan assets and obligations and an entity’s fiscal year-end, the entity should adjust the measurement of defined benefit plan assets and obligations to reflect the effects of those contributions or significant events. However, an entity should not adjust the measurement of defined benefit plan assets and obligations for other events that occur between the month-end measurement and the entity’s fiscal year-end that are not caused by the entity (for example, changes in market prices or interest rates). This practical expedient for the measurement date also applies to significant events that trigger a remeasurement in an interim period. An entity electing the practical expedient for the measurement date is required to disclose the accounting policy election and the date used to measure defined benefit plan assets and obligations in accordance with the amendments in ASU 2015-04. ASU 2015-04 is effective for fiscal years beginning after December 15, 2015. The Company may adopt the standard prospectively. Early adoption is permitted. In the fiscal 2016 first quarter the Company elected to early adopt ASU 2015-04 and apply it on a prospective basis. The Company's plan that provides postretirement medical and other benefits was amended on August 25, 2015. As a result of this plan amendment, the Company elected the practical expedient pursuant to this guidance and a valuation was completed using an August 31, 2015 measurement date. In April 2015 the FASB issued ASU No. 2015-03, "Interest—Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs" (ASU 2015-03). The amendments in ASU 2015-03 simplify the presentation of debt issuance costs and require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. In August 2015 the FASB issued ASU No. 2015-15 "Interest—Imputation of Interest (Subtopic 835-30) Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements" (ASU 2015-15). The guidance in ASU 2015-03 does not address presentation or subsequent measurement of debt issuance costs related to line of credit arrangements. Given the absence of authoritative guidance, in ASU 2015-15, issued in August 2015, FASB adopted SEC staff comments that they would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line of credit arrangement, regardless of whether there are any outstanding borrowings on the line of credit arrangement. ASU 2015-03 and 2015-15 are both effective for fiscal years beginning after December 15, 2015. The amendments are required to be applied retrospectively to all prior periods presented and early adoption is permitted. The Company elected to early adopt ASU 2015-03 in fiscal 2016 first quarter and ASU 2015-15 in fiscal 2016 third quarter. Adoption of this guidance did not have a significant impact on the Company's consolidated financial statements, or results of operations for the period since there were no prior period costs it applied to. Debt issuance costs associated with the credit facility discussed further in Note 10 Financing Arrangements have been presented as an asset and are being amortized ratably over the term of the line of credit arrangement. The adoption of this guidance did not have an impact on the Company's results of operations for the period. In April 2014 the FASB issued ASU No. 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" (ASU No. 2014-08). ASU No. 2014-08 changes the criteria for determining which disposals should be presented as discontinued operations and modifies the related disclosure requirements. Additionally, this guidance requires that a business that qualifies as held for sale upon acquisition should be reported as discontinued operations. This guidance became effective for the Company on February 1, 2015 and applies prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The adoption of this guidance did not have an impact on the Company's consolidated financial statements, results of operations, or disclosures for the period. In addition to the accounting pronouncements adopted and described above, the Company adopted various other accounting pronouncements that became effective in first, second and third quarter fiscal 2016. None of this guidance had a significant impact on the Company's consolidated financial statements, results of operations, or disclosures for the period. New Accounting Standards Not Yet Adopted In November 2015 the FASB issued ASU No. 2015-17, "Income Taxes (Topic 740) Balance Sheet Classification of Deferred Taxes" (ASU 2015-17). Current GAAP requires the deferred taxes for each jurisdiction (or tax-paying component of a jurisdiction) to be presented as a net current asset or liability and net noncurrent asset or liability. This requires a jurisdiction-by-jurisdiction analysis based on the classification of the assets and liabilities to which the underlying temporary differences relate, or, in the case of loss or credit carryforwards, based on the period in which the attribute is expected to be realized. Any valuation allowance is then required to be allocated on a pro rata basis, by jurisdiction, between current and noncurrent deferred tax assets. To simplify presentation, ASU 2015-17 requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. As a result, each jurisdiction will now only have one net noncurrent deferred tax asset or liability. The guidance does not change the existing requirement that only permits offsetting within a jurisdiction - that is, companies are still prohibited from offsetting deferred tax liabilities from one jurisdiction against deferred tax assets of another jurisdiction. ASU 2015-17 is effective for fiscal years beginning after December 15, 2016. The Company may apply the standard either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. Early adoption is permitted. The Company is evaluating the impact the adoption of this guidance will have on its consolidated financial statements and working capital. In September 2015 the FASB issued ASU No. 2015-16, "Business Combinations (Topic 805) Simplifying the Accounting for Measurement-Period Adjustments" (ASU 2015-16). The amendments in ASU 2015-16 apply to all entities that have reported provisional amounts for items in a business combination for which the accounting is incomplete by the end of the reporting period in which the combination occurs and, during the measurement period, have an adjustment to provisional amounts recognized. ASU 2015-16 requires that an acquirer in a business combination recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. ASU 2015-16 requires that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendments in this update require an entity to present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. ASU 2015-16 is to be applied prospectively to adjustments to provisional amounts that occur after the effective date of the update with earlier application permitted for financial statements that have not been issued. The Company is evaluating the impact the adoption of this guidance will have on its consolidated financial statements, results of operations, and disclosures. In July 2015 the FASB issued ASU No. 2015-11, "Inventory (Topic 330) Simplifying the Measurement of Inventory" (ASU 2015-11). The amendments in ASU 2015-11 clarify that an entity should measure inventory within the scope of this update at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Substantial and unusual losses that result from subsequent measurement of inventory should be disclosed in the financial statements. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The amendments are to be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company is evaluating the impact the adoption of this guidance will have on its consolidated financial statements, results of operations, and disclosures. In April 2015 the FASB issued ASU No. 2015-05, "Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement" (ASU 2015-05). The amendments in ASU 2015-05 clarify existing GAAP guidance about a customer’s accounting for fees paid in a cloud computing arrangement with or without a software license. Examples of cloud computing arrangements include software as a service, platform as a service, infrastructure as a service, and other similar hosting arrangements. ASU 2015-05 adds guidance to Subtopic 350-40, Intangibles-Goodwill and Other-Internal-Use Software, which will help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The guidance does not change GAAP for a customer’s accounting for service contracts. All software licenses within the scope of Subtopic 350-40 will be accounted for consistent with other licenses of intangible assets. ASU 2015-05 is effective for fiscal years beginning after December 15, 2015. The amendments may be applied prospectively to all arrangements entered into or materially altered after the effective date or retrospectively to all prior periods presented. Early adoption is permitted. The Company is evaluating the impact the adoption of this guidance will have on its consolidated financial position, results of operations, and cash flows. In February 2015 the FASB issued ASU No. 2015-02, "Consolidation (Topic 810) Amendments to the Consolidation Analysis" (ASU 2015-02). The amendments in ASU 2015-02 affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. Specifically, the amendments: 1. Modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities; 2. Eliminate the presumption that a general partner should consolidate a limited partnership; 3. Affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and 4. Provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940. ASU 2015-02 is effective for fiscal years beginning after December 15, 2015. Early adoption is permitted. ASU 2015-02 may be applied retrospectively or using a modified retrospective approach. The Company is evaluating the impact of this guidance on its consolidated legal entities and on its consolidated financial position, results of operations, and cash flows. In May 2014 the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers" (ASU 2014-09). ASU 2014-09 provides a comprehensive new recognition model that requires recognition of revenue when a company transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to receive in exchange for those goods or services. This guidance supersedes the revenue recognition requirements in FASB ASC Topic 605, “Revenue Recognition,” and most industry-specific guidance. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, companies will need to use more judgment and make more estimates than under the current guidance. It also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts. In August 2015, the FASB approved a one-year deferral of the effective date (ASU 2015-14) and the standard is now effective for the Company for fiscal 2019 and interim periods therein. ASU 2014-09 may be adopted as of the original effective date, which for the Company is fiscal 2018. The guidance may be applied using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The Company is currently evaluating the method and date of adoption and the impact the adoption of ASU 2014-09 will have on the Company’s consolidated financial position, results of operations, and disclosures.

NEW ACCOUNTING STANDARDS

Accounting Standards Adopted

In April 2015 the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-04, "Compensation—Retirement Benefits (Topic 715) Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Assets" (ASU 2015-04). The amendments in ASU 2015-04 allow a reporting entity that may incur more costs than other entities when measuring the fair value of plan assets of a defined benefit pension or other postretirement benefit plan at other than a month-end to measure defined benefit plan assets and obligations using the month-end date that is closest to the date of event (such as a plan amendment, settlement, or curtailment that calls for a remeasurement in accordance with existing requirements) that is triggering the remeasurement. In addition, if a contribution or significant event occurs between the month-end date used to measure defined benefit plan assets and obligations and an entity’s fiscal year-end, the entity should adjust the measurement of defined benefit plan assets and obligations to reflect the effects of those contributions or significant events. However, an entity should not adjust the measurement of defined benefit plan assets and obligations for other events that occur between the month-end measurement and the entity’s fiscal year-end that are not caused by the entity (for example, changes in market prices or interest rates). This practical expedient for the measurement date also applies to significant events that trigger a remeasurement in an interim period. An entity electing the practical expedient for the measurement date is required to disclose the accounting policy election and the date used to measure defined benefit plan assets and obligations in accordance with the amendments in ASU 2015-04. ASU 2015-04 is effective for fiscal years beginning after December 15, 2015. The Company may adopt the standard prospectively. Early adoption is permitted. In the fiscal 2016 first quarter the Company elected to early adopt ASU 2015-04 and apply it on a prospective basis. The Company's plan that provides postretirement medical and other benefits was amended on August 25, 2015. As a result of this plan amendment, the Company elected the practical expedient pursuant to this guidance and a valuation was completed using an August 31, 2015 measurement date.

In April 2015 the FASB issued ASU No. 2015-03, "Interest—Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs" (ASU 2015-03). The amendments in ASU 2015-03 simplify the presentation of debt issuance costs and require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. In August 2015 the FASB issued ASU No. 2015-15 "Interest—Imputation of Interest (Subtopic 835-30) Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements" (ASU 2015-15). The guidance in ASU 2015-03 does not address presentation or subsequent measurement of debt issuance costs related to line of credit arrangements. Given the absence of authoritative guidance, in ASU 2015-15, issued in August 2015, FASB adopted SEC staff comments that they would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line of credit arrangement, regardless of whether there are any outstanding borrowings on the line of credit arrangement. ASU 2015-03 and 2015-15 are both effective for fiscal years beginning after December 15, 2015. The amendments are required to be applied retrospectively to all prior periods presented and early adoption is permitted. The Company elected to early adopt ASU 2015-03 in fiscal 2016 first quarter and ASU 2015-15 in fiscal 2016 third quarter. Adoption of this guidance did not have a significant impact on the Company's consolidated financial statements, or results of operations for the period since there were no prior period costs it applied to. Debt issuance costs associated with the credit facility discussed further in Note 10 Financing Arrangements have been presented as an asset and are being amortized ratably over the term of the line of credit arrangement. The adoption of this guidance did not have an impact on the Company's results of operations for the period.

In April 2014 the FASB issued ASU No. 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" (ASU No. 2014-08). ASU No. 2014-08 changes the criteria for determining which disposals should be presented as discontinued operations and modifies the related disclosure requirements. Additionally, this guidance requires that a business that qualifies as held for sale upon acquisition should be reported as discontinued operations. This guidance became effective for the Company on February 1, 2015 and applies prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The adoption of this guidance did not have an impact on the Company's consolidated financial statements, results of operations, or disclosures for the period.

In addition to the accounting pronouncements adopted and described above, the Company adopted various other accounting pronouncements that became effective in first, second and third quarter fiscal 2016. None of this guidance had a significant impact on the Company's consolidated financial statements, results of operations, or disclosures for the period.

New Accounting Standards Not Yet Adopted

In November 2015 the FASB issued ASU No. 2015-17, "Income Taxes (Topic 740) Balance Sheet Classification of Deferred Taxes" (ASU 2015-17). Current GAAP requires the deferred taxes for each jurisdiction (or tax-paying component of a jurisdiction) to be presented as a net current asset or liability and net noncurrent asset or liability. This requires a jurisdiction-by-jurisdiction analysis based on the classification of the assets and liabilities to which the underlying temporary differences relate, or, in the case of loss or credit carryforwards, based on the period in which the attribute is expected to be realized. Any valuation allowance is then required to be allocated on a pro rata basis, by jurisdiction, between current and noncurrent deferred tax assets. To simplify presentation, ASU 2015-17 requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. As a result, each jurisdiction will now only have one net noncurrent deferred tax asset or liability. The guidance does not change the existing requirement that only permits offsetting within a jurisdiction - that is, companies are still prohibited from offsetting deferred tax liabilities from one jurisdiction against deferred tax assets of another jurisdiction. ASU 2015-17 is effective for fiscal years beginning after December 15, 2016. The Company may apply the standard either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. Early adoption is permitted. The Company is evaluating the impact the adoption of this guidance will have on its consolidated financial statements and working capital.

In September 2015 the FASB issued ASU No. 2015-16, "Business Combinations (Topic 805) Simplifying the Accounting for Measurement-Period Adjustments" (ASU 2015-16). The amendments in ASU 2015-16 apply to all entities that have reported provisional amounts for items in a business combination for which the accounting is incomplete by the end of the reporting period in which the combination occurs and, during the measurement period, have an adjustment to provisional amounts recognized. ASU 2015-16 requires that an acquirer in a business combination recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. ASU 2015-16 requires that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendments in this update require an entity to present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. ASU 2015-16 is to be applied prospectively to adjustments to provisional amounts that occur after the effective date of the update with earlier application permitted for financial statements that have not been issued. The Company is evaluating the impact the adoption of this guidance will have on its consolidated financial statements, results of operations, and disclosures.

In July 2015 the FASB issued ASU No. 2015-11, "Inventory (Topic 330) Simplifying the Measurement of Inventory" (ASU 2015-11). The amendments in ASU 2015-11 clarify that an entity should measure inventory within the scope of this update at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Substantial and unusual losses that result from subsequent measurement of inventory should be disclosed in the financial statements. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The amendments are to be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The Company is evaluating the impact the adoption of this guidance will have on its consolidated financial statements, results of operations, and disclosures.

In April 2015 the FASB issued ASU No. 2015-05, "Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement" (ASU 2015-05). The amendments in ASU 2015-05 clarify existing GAAP guidance about a customer’s accounting for fees paid in a cloud computing arrangement with or without a software license. Examples of cloud computing arrangements include software as a service, platform as a service, infrastructure as a service, and other similar hosting arrangements. ASU 2015-05 adds guidance to Subtopic 350-40, Intangibles-Goodwill and Other-Internal-Use Software, which will help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The guidance does not change GAAP for a customer’s accounting for service contracts. All software licenses within the scope of Subtopic 350-40 will be accounted for consistent with other licenses of intangible assets. ASU 2015-05 is effective for fiscal years beginning after December 15, 2015. The amendments may be applied prospectively to all arrangements entered into or materially altered after the effective date or retrospectively to all prior periods presented. Early adoption is permitted. The Company is evaluating the impact the adoption of this guidance will have on its consolidated financial position, results of operations, and cash flows.

In February 2015 the FASB issued ASU No. 2015-02, "Consolidation (Topic 810) Amendments to the Consolidation Analysis" (ASU 2015-02). The amendments in ASU 2015-02 affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. Specifically, the amendments: 1. Modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities; 2. Eliminate the presumption that a general partner should consolidate a limited partnership; 3. Affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and 4. Provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940. ASU 2015-02 is effective for fiscal years beginning after December 15, 2015. Early adoption is permitted. ASU 2015-02 may be applied retrospectively or using a modified retrospective approach. The Company is evaluating the impact of this guidance on its consolidated legal entities and on its consolidated financial position, results of operations, and cash flows.

In May 2014 the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers" (ASU 2014-09). ASU 2014-09 provides a comprehensive new recognition model that requires recognition of revenue when a company transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to receive in exchange for those goods or services. This guidance supersedes the revenue recognition requirements in FASB ASC Topic 605, “Revenue Recognition,” and most industry-specific guidance. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, companies will need to use more judgment and make more estimates than under the current guidance. It also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts. In August 2015, the FASB approved a one-year deferral of the effective date (ASU 2015-14) and the standard is now effective for the Company for fiscal 2019 and interim periods therein. ASU 2014-09 may be adopted as of the original effective date, which for the Company is fiscal 2018. The guidance may be applied using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The Company is currently evaluating the method and date of adoption and the impact the adoption of ASU 2014-09 will have on the Company’s consolidated financial position, results of operations, and disclosures.
