Accounting Policies [Abstract] |
New Accounting Pronouncements, Policy | New Accounting Pronouncements In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes, which amends the existing guidance to require presentation of deferred tax assets and liabilities as non-current within a classified statement of financial position. This guidance was adopted, on a prospective basis, at September 1, 2015. Prior periods were not retrospectively adjusted. In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, which includes amendments that 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. Under the new rule, the recognition and measurement of debt issuance costs is not affected. This guidance is effective for fiscal years beginning on or after December 15, 2015. The adoption of this standard in fiscal 2017 is not expected to have a material impact on the financial statements of the Company. In September 2015, the FASB issued ASU 2015-16, Simplifying the Accounting for Measurement-Period Adjustments, which eliminates the requirement to retrospectively account for changes to provisional amounts initially recorded in a business acquisition opening balance sheet. This standard is effective for fiscal years beginning after December 15, 2015 (fiscal 2017 for the Company), including interim periods within fiscal years. The adoption of this standard is not expected to have a material impact on the financial statements of the Company. In March 2016, the FASB issued ASU 2016-09, "Stock Compensation: Improvements to Employee Share-Based Payment Accounting," which will simplify several aspects of accounting for share-based payment transactions. The guidance will require, among other items, that all excess tax deficiencies or benefits be recorded as income tax expense or benefit in the statement of earnings, and not in additional paid-in capital (shareholder's equity). This guidance is effective for fiscal years beginning after December 15, 2016 (fiscal 2018 for the Company), and interim periods within those annual periods. The Company is currently evaluating the impact of adopting this standard. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. Under ASU 2014-09 and subsequent updates included in ASU 2016-10 and ASU 2016-12, an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. This guidance is effective for fiscal years beginning on or after December 15, 2017 (fiscal 2019 for the Company). The Company is currently evaluating the impact of adopting this standard. In February 2016, the FASB issued ASU 2016-02, Leases which requires recognizing all lease transactions (with terms in excess of 12 months) on the balance sheet as a lease liability and a right-of-use asset. This new rule is effective for fiscal years beginning after December 15, 2018 (fiscal 2020 of the Company), including interim periods within those fiscal years. Upon adoption, the lessee will apply the new standard retrospectively to all periods presented or retrospectively using a cumulative effect adjustment in the year of adoption. The Company is currently evaluating the impact of adopting this standard. In August 2016, the FASB issued ASU 2016‑15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments, to address how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. This guidance is effective for fiscal years beginning after December 15, 2017 (fiscal 2019 of the Company), including interim periods within those fiscal years. This update will require adoption on a retrospective basis unless it is impracticable to apply. The Company is currently evaluating the impact of adopting this standard.
Costs Associated with Exit or Disposal Actitivies or Restructurings, Policy | Restructuring: The Company has committed to various restructuring initiatives including workforce reductions, plant consolidations to reduce manufacturing overhead, satellite office closures, the continued movement of production and product sourcing to low cost alternatives and the centralization and standardization of certain administrative functions. Total restructuring charges for these activities were $14.6 million in fiscal 2016 and impacted all segments. Liabilities for severance will be paid during the next twelve months, while future lease payments related to facilities vacated as a result of restructuring will be paid over the underlying remaining lease terms. The following is a rollforward of fiscal 2016 restructuring activities, by segment, (in thousands):

Goodwill and Intangible Assets, Policy [Policy Text Block] | Goodwill and Other Intangible Assets: Other intangible assets with definite lives, consisting primarily of purchased customer relationships, patents, trademarks and non-compete agreements, are amortized over periods from one to twenty-five years. Goodwill and other intangible assets with indefinite lives are not subject to amortization, but are subject to annual impairment testing. The Company’s goodwill is tested for impairment annually, during the fourth quarter, or more frequently if events or changes in circumstances indicate that goodwill might be impaired. The Company performs impairment reviews for its reporting units using a fair value method based on management’s judgments and assumptions. In estimating the fair value, the Company utilizes a discounted cash flow model, which is dependent on a number of assumptions including estimated future revenues and expenses, weighted average cost of capital, capital expenditures and other variables. The estimated fair value of the reporting unit is compared to the carrying amount of the reporting unit, including goodwill. If the carrying value of the reporting unit exceeds its fair value, the goodwill is potentially impaired and the Company then determines the implied fair value of goodwill, which is compared to the carrying value to determine if impairment exists. Indefinite lived intangible assets are also subject to an annual impairment test. On an annual basis, or more frequently if events or changes in circumstances indicate that the asset might be impaired, the fair value of the indefinite lived intangible assets are evaluated by the Company to determine if an impairment charge is required. A considerable amount of management judgment is required in performing the impairment tests, principally in determining the fair value of each reporting unit and the indefinite lived intangible assets.
