New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Adoption of new Accounting Standards	Adoption of New Accounting Standards In May 2014 the Financial Accounting Standards Board (FASB) issued the Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606), that will supersede nearly all existing revenue recognition guidance under US GAAP. The core principle of the guidance is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard was originally to be effective for public entities for annual and interim periods beginning after December 15, 2016. On July 9, 2015 the FASB decided to defer by one year the effective dates of the new standard for both public and nonpublic entities reporting under US GAAP. Early adoption would be permitted for all entities, but not before the original public entity effective date (i.e. annual and interim periods beginning after December 16, 2016). Entities can choose to apply the standard using either the full retrospective approach or a modified retrospective approach. Entities electing the full retrospective adoption will apply the standard to each period presented in the financial statements. This means that entities will have to apply the new guidance as if it had been in effect since the inception of all its contracts with customers presented in the financial statements. Entities that elect the modified retrospective approach will apply the guidance retrospectively only to the most current period presented in the financial statements. This means that entities will have to recognize the cumulative effect of initially applying the new standard as an adjustment to the opening balance of retained earnings at the date of initial application. The new revenue standard will be applied to contracts that are in progress at the date of initial application. The Company will adopt ASU 2014-09 in the first quarter of 2018 and apply the modified retrospective approach. The Company has continued to monitor FASB activity related to the new standard and is currently assessing existing contracts with customers as a part of determining the potential effect the new standard will have on its consolidated financial statements. The Company currently anticipates that the adoption of ASU No. 2014-09 could impact the accounting treatment of certain contracts, as well as pre-production engineering, development and tooling costs related to products manufactured for our customers under long-term supply agreements. In February 2016, the FASB issued ASU 2016-02, Leases, which provides guidance for lease accounting. The new guidance contained in the ASU stipulates that lessees will need to recognize a right-of-use asset and a lease liability for substantially all leases (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of lease payments. Treatment in the consolidated statements of earnings will be similar to the current treatment of operating and capital leases. The new guidance is effective on a modified retrospective basis for the Company in the first quarter of its fiscal year ending December 31, 2019. The Company is currently in the process of evaluating the impact of adoption of this standard on its consolidated financial statements. Upon adoption, the Company does not anticipate a material impact on the Company's Consolidated Financial Statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which amends Accounting Standards Codification ("ASC") Topic 718, Compensation - Stock Compensation. ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Under previous guidance, excess tax benefits and deficiencies from stock-based compensation arrangements were recorded in equity when the awards vested or were settled. ASU 2016-09 requires prospective recognition of excess tax benefits and deficiencies in the income statement as a component of the income tax provision. In addition, under ASU 2016-09, excess income tax benefits from stock-based compensation arrangements are classified as cash flow from operations, rather than as cash flow from financing activities. ASU 2016-09 also allows for the Company to make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. The Company will continue to apply its existing entity-wide policy to estimate the number of awards expected to be forfeited. Impact to Consolidated Statements of Income One of the more significant impacts of adopting ASU 2016-09 is the required change in how the Company recognizes the excess tax benefits or deficiencies related to share-based compensation. For example, prior to adopting ASU 2016-09 such benefits and deficiencies were credited or charged, respectively, to additional paid-in capital in the Company’s Consolidated Balance Sheets. Under ASU 2016-09, these benefits and deficiencies are recognized as a discrete tax benefit or discrete tax expense, in the Company’s Consolidated Statements of Income. For the three months ended March 31, 2017, the Company recognized a discrete tax benefit of $1.8 million related to net tax benefits from share-based compensation. ASU 2016-09 requires companies to adopt the amendment related to accounting for benefits and deficiencies on a prospective basis only. As a result, no change has been made to the Consolidated Statements of Income for the three months ended March 31, 2016 related to the $0.4 million of net tax expense the Company recognized as additional paid-in capital during such three months. Net tax expense of $0.4 million recognized as additional paid-in-capital during the three months ended March 31, 2016 includes gross tax benefits of $0.1 million net of $0.5 million tax expense. In consideration of the impact of the adoption of this standard to earnings per share, the total impact of adoption of this standard to the earnings per share calculation was less than $.01 for the three month periods ending March 31, 2017. Impact to Consolidated Statements of Cash Flows In addition to the income tax consequences described above, under ASU 2016-09 all tax benefits related to share-based payments are reported as cash flows from operating activities along with all other income tax cash flows. Previously, tax benefits from share-based payment arrangements were reported as cash flows from financing activities. With respect to the classification of tax benefits on the statement of cash flows, ASU 2016-09 allows companies to elect either a prospective or retrospective application. The Company has elected to apply this classification amendment retrospectively. As a result, the Company elected to reclassify $0.4 million of tax expense previously reported as cash flows from financing activities on the Company’s Consolidated Statement of Cash Flows for the three months ended March 31, 2016 as cash flows from operating activities. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows, which updates the guidance as to how certain cash receipts and cash payments should be presented and classified within the statement of cash flows. The update is intended to reduce the existing diversity in practice. The amended guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted, including adoption in an interim period. The Company is in the process of assessing the potential effect the new standard will have on its consolidated financial statements.

Adoption of New Accounting Standards
