Basis of Presentation	Note 1 . Basis of Presentation The condensed consolidated financial statements of II-VI Incorporated (“II-VI” or the “Company”) for the three and nine months ended March 31, 2016 and 2015 are unaudited. In the opinion of management, all adjustments considered necessary for a fair presentation for the periods presented have been included. All adjustments are of a normal recurring nature unless disclosed otherwise. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2015. The consolidated results of operations for the three and nine months ended March 31, 2016 are not necessarily indicative of the results to be expected for the full fiscal year.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Recent Accounting Pronouncements	Note 2 . Recent Accounting Pronouncements Adopted Pronouncements In November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. This update requires all deferred tax assets and liabilities, and any related valuation allowance, to be classified as noncurrent on the balance sheet. The classification change for all deferred taxes as noncurrent simplifies the Company’s processes as it eliminates the need to separately identify the net current and net noncurrent deferred tax asset or liability in each jurisdiction and allocate valuation allowances. The Company has elected to prospectively adopt the accounting standard in the quarter ended December 31, 2015. The adoption of this standard resulted in the reclassification of $13.3 million from current Deferred income tax assets in the Consolidated Balance Sheet as of December 31, 2015 to noncurrent Deferred income tax assets and $1.0 million from current Deferred income tax liabilities to noncurrent Deferred income tax liabilities. Prior periods in the Company’s Consolidated Financial Statements were not retrospectively adjusted. Pronouncements Currently Under Evaluation In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This update simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, and classification in the statement of cash flows. The standard will be effective for the Company’s 2017 fiscal year. Early adoption is permitted. The Company is evaluating the impact of this guidance on the Company’s Consolidated Financial Statements. In March 2016, the FASB issued ASU 2016-07, Investments – Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting. This update requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The standard will be effective for the Company’s 2017 fiscal year. Early adoption is permitted. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This update requires that a lessee recognize leased assets with terms greater than 12 months on the balance sheet for the rights and obligations created by those leases. The standard will be effective for the Company’s 2019 fiscal year. Early adoption is permitted. The Company is evaluating the impact of this guidance on the Company’s Consolidated Financial Statements. In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. This update requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The standard will be effective for the Company’s 2017 fiscal year. Early adoption is permitted. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This update simplifies the measurement of inventory valuation at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The new inventory measurement requirements will be effective for the Company’s 2018 fiscal year and will replace the current inventory valuation guidance that requires the use of a lower of cost or market framework. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements. In April 2015, the FASB issued ASU 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. This update provides guidance about whether a cloud computing arrangement includes a software license. The update will be effective for the Company’s 2017 fiscal year. Early adoption is permitted. The update allows for the use of either a prospective or retrospective adoption approach. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements. In April 2015, the FASB issued ASU 2015-03, Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. This ASU requires entities to present debt issuance costs in the balance sheet as a direct deduction from the carrying amount of the corresponding debt liability, consistent with debt discounts. The update will be effective for the Company’s 2017 fiscal year. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements. In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis, which affects reporting organizations that are required to evaluate whether they should consolidate certain legal entities. The update will be effective for the Company’s 2017 fiscal year. Early adoption is permitted, including adoption in an interim period. The update allows for the use of either a full retrospective or a modified retrospective adoption approach. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements. In May 2014, the FASB issued ASU 2014-09: Revenue from Contracts with Customers (Topic 606) which supersedes virtually all existing revenue recognition guidance under U.S. GAAP. The update's core principle is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The update allows for the use of either the retrospective or modified retrospective approach of adoption. On July 9, 2015 the FASB approved a one year deferral of the effective date of the update. The update will be effective for the Company’s 2019 fiscal year. We have not yet selected a transition method and are currently evaluating the impact of this guidance on the Company’s Consolidated Financial Statements.

Business Combinations [Abstract]
Acquisitions	Note 3. Acquisitions EpiWorks, Inc. In February 2016, the Company acquired all the outstanding shares of EpiWorks, Inc. (“EpiWorks”) a privately held company based in Illinois. Under the terms of the merger agreement, the consideration consisted of initial cash paid at the acquisition date of $43.0 million, net of cash acquired and a working capital adjustment of $0.2 million. In addition, the agreement provides up to a maximum of $6.0 million of additional cash earnout opportunities based upon EpiWorks achieving certain agreed upon financial and operational targets for capacity, wafer output and gross margin, which if earned would be payable $2.0 million for the achievement of each specific target over the next three years. EpiWorks develops and manufactures compound semiconductor epitaxial wafers for applications in optical components, wireless devices and high-speed communication systems. EpiWorks is a business unit of the Company’s II-VI Laser Solutions operating segment for financial reporting purposes. Due to the timing of the acquisition, the Company is still in the process of completing its fair market valuation, including the valuation of certain tangible and intangible assets, earnout opportunities, as well as deferred income taxes. The following table presents the allocation of the purchase price of the assets acquired and liabilities assumed at the date of acquisition ($000): Net cash paid at acquisition $ 42,981 Cash paid for working capital adjustment 163 Fair value of cash earnout arrangement 6,000 Purchase price $ 49,144 The following table presents the preliminary allocation of the purchase price of the assets acquired and liabilities assumed at the date of acquisition, as the Company intends to finalize its accounting for the acquisition of EpiWorks within one year from the date of acquisition ($000): Assets Accounts receivable $ 2,121 Inventories 2,435 Prepaid and other assets 68 Property, plant & equipment 9,184 Intangible assets 19,911 Goodwill 24,133 Total assets acquired $ 57,852 Liabilities Accounts payable $ 605 Other accrued liabilities 859 Deferred tax liabilities 7,244 Total liabilities assumed 8,708 Net assets acquired $ 49,144 The goodwill of $24.1 million is included in the II-VI Laser Solutions segment and is attributed to the expected synergies and the assembled workforce of EpiWorks. None of the goodwill is deductible for income tax purposes. The fair value of accounts receivable acquired was $2.1 million with the gross contractual amount being $2.1 million. At the time of acquisition, the Company expected to collect all of the accounts receivable. The amount of revenues and net loss of EpiWorks included in the Company’s Consolidated Statement of Earnings were $1.0 million and $1.2 million, respectively, for the three and nine months ended March 31, 2016. ANADIGICS, Inc. In March 2016, the Company acquired all the outstanding shares of ANADIGICS, Inc. (Nasdaq:ANAD) (“ANADIGICS”) a publicly traded company based in New Jersey. Under the terms of the merger agreement, the consideration consisted of cash paid at the acquisition date of $75.5 million, net of cash acquired of $2.7 million. ANADIGICS has a 6-inch gallium arsenide wafer fabrication capability allowing for the production of high performance lasers and integrated circuits in high volume. In addition, ANADIGICS designs and manufactures innovative radio frequency (RF) solutions for CATV infrastructure, small-cell, WIFI and cellular markets. ANADIGICS is a business unit of the Company’s II-VI Laser Solutions operating segment for financial reporting purposes. Due to the timing of the acquisition, the Company is still in the process of completing its fair market valuation, including the valuation of certain tangible and intangible assets as well as deferred income taxes. The following table presents the preliminary allocation of the purchase price of the assets acquired and liabilities assumed at the date of acquisition as the Company intends to finalize its accounting for the acquisition of ANADIGICS within one year from the date of acquisition ($000): Assets Accounts receivable $ 3,973 Inventories 8,322 Prepaid and other assets 2,347 Property, plant & equipment 41,500 Intangible assets 23,537 Goodwill 21,060 Total assets acquired $ 100,739 Liabilities Accounts payable $ 3,586 Other accrued liabilities 10,726 Deferred tax liabilities 10,915 Total liabilities assumed 25,227 Net assets acquired $ 75,512 The goodwill of $21.1 million is included in the II-VI Laser Solutions segment and is attributed to the expected synergies and the assembled workforce of ANADIGICS. None of the goodwill is deductible for income tax purposes. The fair value of accounts receivable acquired was $4.0 million with the gross contractual amount being $4.0 million. At the time of acquisition, the Company expected to collect all of the accounts receivable. The amount of revenues and net loss of ANADIGICS included in the Company’s Consolidated Statement of Earnings were $3.2 million and $2.9 million, respectively, for the three and nine months ended March 31, 2016. Deferred Income Taxes In connection with above acquisitions, the Company recorded a valuation allowance of $29.0 million against the U.S. net deferred income tax assets as part of the preliminary purchase price allocation. The Company’s policy is to allocate the available sources of future taxable income first to the Company’s existing deferred tax assets before considering acquired deferred tax assets. Pro Forma Information The following unaudited pro forma consolidated results of operations for the three and nine months ended March 31, 2016 and 2015 have been prepared as if the acquisitions of EpiWorks and ANADIGICS had occurred on July 1, 2014, the beginning of the Company’s fiscal year 2015, which is the fiscal year prior to the acquisitions. As a result, certain transaction related expenses of $2.8 million and $3.1 million, respectively, (net of tax) recorded in Selling, general and administrative in the Company’s Condensed Consolidated Statement of Earnings for the three and nine months ended March 31, 2016 were only included in the earliest period presented below ($000 except per share data).

The term loan is being repaid in consecutive quarterly principal payments on the first business day of each January, April, July and October, with the first payment having commenced on October 1, 2013, as follows: (i) twenty consecutive quarterly installments of $5 million and (ii) a final installment of all remaining principal due and payable on the maturity date of September 10, 2018. Amounts borrowed under the revolving credit facility are due and payable on the maturity date. The Credit Facility is unsecured, but is guaranteed by each existing and subsequently acquired or organized wholly-owned domestic subsidiary of the Company. The Company has the option to request an increase to the size of the revolving credit facility in an aggregate additional amount not to exceed $100 million. The Credit Facility has a five-year term through September 10, 2018 and has an interest rate of either a Base Rate Option or a Euro-Rate Option, plus an Applicable Margin, as defined in the agreement governing the Credit Facility. If the Base Rate option is selected for a borrowing, the Applicable Margin is 0.00% to 0.075% and if the Euro-Rate Option is selected for a borrowing, the Applicable Margin is 0.75% to 1.75%. The Applicable Margin is based on the Company’s ratio of consolidated indebtedness to consolidated EBITDA. Additionally, the Credit Facility is subject to certain covenants, including those relating to minimum interest coverage and maximum leverage ratios. As of March 31, 2016, the Company was in compliance with all financial covenants under its Credit Facility. The Company’s Yen denominated line of credit is a 500 million Yen (approximately $4.5 million) facility. The Yen line of credit was extended in September 2015 through August 2020 on substantially the same terms. The interest rate is equal to LIBOR, as defined in the loan agreement, plus 0.625% to 1.50%. At each of March 31, 2016 and June 30, 2015, the Company had 300 million Yen borrowed.

Income Taxes	Note 9 . Income Taxes The Company’s year-to-date effective income tax rate at March 31, 2016 and 2015 was 17.1% and 13.6%, respectively. The variations between the Company’s effective tax rate and the U.S. statutory rate of 35.0% were primarily due to the consolidation of the Company’s foreign operations, which are subject to income taxes at lower statutory rates. U.S. GAAP clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. As of March 31, 2016 and June 30, 2015, the Company’s gross unrecognized income tax benefit was $4.6 million and $4.0 million, respectively. The Company has classified the uncertain tax positions as noncurrent income tax liabilities, as the amounts are not expected to be paid within one year. If recognized, substantially all of the gross unrecognized tax benefits at March 31, 2016 would impact the effective tax rate. The Company recognizes interest and penalties related to uncertain tax positions in the income tax provision on the Condensed Consolidated Statements of Earnings. The amount of accrued interest and penalties included in the $4.6 million and $4.0 million of gross unrecognized income tax benefit at March 31, 2016 and June 30, 2015, respectively, was immaterial. Fiscal years 2013 to 2015 remain open to examination by the United States Internal Revenue Service, fiscal years 2011 to 2015 remain open to examination by certain state jurisdictions, and fiscal years 2008 to 2015 remain open to examination by certain foreign taxing jurisdictions. The Company’s fiscal year 2011 and 2012 California state income tax returns are currently under examination by the state of California’s Franchise Tax Board. The Company’s fiscal year 2012 and 2013 German income tax returns are currently under examination by the Federal Central Tax Office in Germany.

Segment Reporting [Abstract]
Segment Reporting	Note 11 . Segment Reporting The Company reports its business segments using the “management approach” model for segment reporting. This means that the Company determines its reportable business segments based on the way the chief operating decision maker organizes business segments within the Company for making operating decisions and assessing performance. The Company reports its financial results in the following three segments: (i) II-VI Laser Solutions, (ii) II-VI Photonics, and (iii) II-VI Performance Products, and the Company’s chief operating decision maker receives and reviews financial information based on these segments. The Company evaluates business segment performance based upon segment operating income, which is defined as earnings before income taxes, interest and other income or expense. The segments are managed separately due to the market, production requirements and facilities unique to each segment. The II-VI Laser Solutions segment is located in the U.S., Singapore, China, Germany, Switzerland, Japan, Belgium, the U.K., Italy, South Korea and the Philippines. II-VI Laser Solutions is directed by the President of II-VI Laser Solutions, while each geographic location is directed by a general manager, and is further divided into production and administrative units that are directed by managers. II-VI Laser Solutions designs, manufactures and markets optical and electro-optical components and materials sold under the II-VI Infrared brand name and used primarily in high-power CO 2 The II-VI Photonics segment is located in the U.S., China, Vietnam, Germany, Japan, the U.K., Italy and Hong Kong. II-VI Photonics is directed by the President of II-VI Photonics and is further divided into production and administrative units that are directed by managers. II-VI Photonics manufactures crystal materials, optics, microchip lasers and opto-electronic modules for use in optical communication networks and other diverse consumer and commercial applications. In addition, the segment also manufactures pump lasers, optical amplifiers and micro-optics for optical amplifiers for both terrestrial and submarine applications within the optical communications market. The II-VI Performance Products segment is located in the U.S., Vietnam, Japan, China, Germany and the Philippines. II-VI Performance Products is directed by the President of II-VI Performance Products, while each geographic location is directed by a general manager.

II-VI Performance Products designs, manufactures and markets infrared optical components and high-precision optical assemblies for military, medical and commercial laser imaging applications. In addition, the segment designs, manufactures and markets unique engineered materials for thermo-electric and silicon carbide applications servicing the semiconductor, military and medical markets. The accounting policies of the segments are the same as those of the Company. The Company’s corporate expenses are allocated to the segments. The Company evaluates segment performance based upon reported segment operating income, which is defined as earnings from continuing operations before income taxes, interest and other income or expense. Inter-segment sales and transfers are eliminated. On February 1, 2016, the Company completed its acquisition of EpiWorks. On March 15, 2016, the Company completed its acquisition of ANADIGICS. See Note 3. Acquisitions. The operating results of these acquisitions have been reflected in the selected financial information of the Company’s II-VI Laser Solutions segment since the respective dates of acquisition.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Share-Based Compensation	Note 12. Share-Based Compensation The Board of Directors adopted the II-VI Incorporated Second Amended and Restated 2012 Omnibus Incentive Plan (the “Plan”), which was approved by the shareholders at the Annual Meeting in November 2015. The Plan provides for the grant of performance-based cash incentive awards, non-qualified stock options, stock appreciation rights, restricted share awards, restricted share units, deferred share awards, performance share awards and performance share units to employees, officers and directors of the Company. The maximum number of shares of the Company’s common stock authorized for issuance under the Plan is limited to 4,900,000 shares of common stock, not including any remaining shares forfeited under the predecessor plans that may be rolled into the Plan. The Company records share-based compensation expense for these awards in accordance with U.S. GAAP, which requires the recognition of grant-date fair value of share-based compensation in net earnings and over the requisite service period of the individual grantees, which generally equals the vesting period. The Company accounts for cash-based stock appreciation rights, cash-based restricted share unit awards and cash-based performance share unit awards as liability awards, in accordance with applicable accounting standards. Share-based compensation expense is allocated approximately 15% to cost of goods sold and 85% to selling, general and administrative expense, based on the employee classification of the grantees. Share-based compensation expense for the periods indicated was as follows ($000): Three Months Ended Nine Months Ended March 31, 2016 2015 2016 2015 Stock Options and Cash-Based Stock Appreciation Rights $ 755 $ 1,172 $ 3,892 $ 4,387 Restricted Share Awards and Cash-Based Restricted Share Unit Awards 991 1,109 3,776 3,268 Performance Share Awards and Cash-Based Performance Share Unit Awards 762 1,331 2,438 2,321 $ 2,508 $ 3,612 $ 10,106 $ 9,976

Fair Value of Financial Instrum

Fair Value of Financial Instruments	9 Months Ended

Business Combinations [Abstract]
Fair Value of Financial Instruments	Note 13. Fair Value of Financial Instruments The FASB defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous markets for the asset and liability in an orderly transaction between market participants at the measurement date. The Company estimates fair value of its financial instruments utilizing an established three-level hierarchy in accordance with U.S. GAAP. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date as follows: • Level 1 – Valuation is based upon unadjusted quoted prices for identical assets or liabilities in active markets. • Level 2 – Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instruments. • Level 3 – Valuation is based upon other unobservable inputs that are significant to the fair value measurements. The classification of fair value measurements within the hierarchy is based upon the lowest level of input that is significant to the measurement. At March 31, 2016, the Company had foreign currency forward contracts recorded at fair value. The fair values of these instruments were measured using valuations based upon quoted prices for similar assets and liabilities in active markets (Level 2) and are valued by reference to similar financial instruments, adjusted for credit risk and restrictions and other terms specific to the contracts. Foreign currency gain related to these contracts was immaterial for the three and nine months ended March 31, 2016. At March 31, 2016, the Company had a contingent earnout arrangement related to the acquisition of EpiWorks recorded at fair value. The EpiWorks earnout arrangement provides up to a maximum of $6.0 million of additional cash payments to the former shareholders based upon EpiWorks achieving certain agreed upon financial and operational targets for capacity, wafer output and gross margin, which if earned would be payable $2.0 million for the achievement of each specific target over the next three years. As of March 31, 2016, the Company has made no earnout payments. Due to the timing of the acquisition, the Company is still in the process of completing its fair market valuation of the earnout arrangement. The Company has recorded the fair value of the earnout arrangement of $2.0 million in Other accrued liabilities and $4.0 million in Other liabilities in the Condensed Consolidated Balance Sheets. The fair value of the earnout arrangement was based on significant inputs not observable in the market and represents a Level 3 measurement as defined by U.S. GAAP. The following table provides a summary by level of the fair value of financial instruments that are measured on a recurring basis for the periods presented ($000): Fair Value Measurements at March 31, 2016 Using: Quoted Prices in Significant Active Markets Other Significant for Identical Observable Unobservable Assets Inputs Inputs March 31, 2016 (Level 1) (Level 2) (Level 3) Liabilities: Foreign currency forward contracts $ 99 $ - $ 99 $ - Contingent earnout arrangement $ 6,000 $ - $ - $ 6,000 Fair Value Measurements at June 30, 2015 Using: Quoted Prices in Significant Active Markets Other Significant for Identical Observable Unobservable Assets Inputs Inputs June 30, 2015 (Level 1) (Level 2) (Level 3) Assets: Foreign currency forward contracts $ 130 $ - $ 130 $ - The Company’s policy is to report transfers into and out of Levels 1 and 2 of the fair value hierarchy at fair values as of the beginning of the period in which the transfers occur. There were no transfers in and out of Levels 1 and 2 of the fair value hierarchy during the three and nine months ended March 31, 2016. The following table presents a reconciliation of the beginning and ending fair value measurements of the Company’s level 3 contingent earnout arrangement related to the acquisition of EpiWorks ($000): Significant Unobservable Inputs (Level 3) Balance at July 1, 2015 $ - Contingent earnout arrangement 6,000 Payments - Changes in fair value - Balance at March 31, 2016 $ 6,000 The fair values of cash and cash equivalents are considered Level 1 among the fair value hierarchy and approximate fair value because of the short-term maturity of those instruments. The Company’s borrowings are considered Level 2 among the fair value hierarchy and are variable interest rates and accordingly their carrying amounts approximate fair value.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments	Note 14. Derivative Instruments The Company, from time to time, purchases foreign currency forward exchange contracts, primarily in Japanese Yen, that permit it to sell specified amounts of these foreign currencies expected to be received from its export sales for pre-established U.S. dollar amounts at specified dates. The Company enters into these contracts to limit transactional exposure to changes in currency exchange rates of export sales transactions in which settlement will occur in future periods and which otherwise would expose the Company, on the basis of its aggregate net cash flows in respective currencies, to foreign currency risk. The Company has recorded the fair market value of these contracts in the Company’s Condensed Consolidated Financial Statements. These contracts had a total notional amount of $5.8 million and $10.8 million at March 31, 2016 and June 30, 2015, respectively. As of March 31, 2016, these forward contracts had expiration dates ranging from April 2016 through July 2016, with Japanese Yen denominations individually ranging from 100 million Yen to 200 million Yen. The Company does not account for these contracts as hedges as defined by U.S. GAAP, and records the change in the fair value of these contracts in Other expense (income), net in the Condensed Consolidated Statements of Earnings as they occur. The fair value measurement takes into consideration foreign currency rates and the current creditworthiness of the counterparties to these contracts, as applicable, and is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instruments and thus represents a Level 2 measurement. These contracts are recorded in Other liabilities in the Company’s Condensed Consolidated Balance Sheets. The change in the fair value of these contracts for each of the three and nine months ended March 31, 2016 and 2015 was insignificant.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Recent Accounting Pronouncements	Adopted Pronouncements In November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. This update requires all deferred tax assets and liabilities, and any related valuation allowance, to be classified as noncurrent on the balance sheet. The classification change for all deferred taxes as noncurrent simplifies the Company’s processes as it eliminates the need to separately identify the net current and net noncurrent deferred tax asset or liability in each jurisdiction and allocate valuation allowances. The Company has elected to prospectively adopt the accounting standard in the quarter ended December 31, 2015. The adoption of this standard resulted in the reclassification of $13.3 million from current Deferred income tax assets in the Consolidated Balance Sheet as of December 31, 2015 to noncurrent Deferred income tax assets and $1.0 million from current Deferred income tax liabilities to noncurrent Deferred income tax liabilities. Prior periods in the Company’s Consolidated Financial Statements were not retrospectively adjusted. Pronouncements Currently Under Evaluation In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This update simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, and classification in the statement of cash flows. The standard will be effective for the Company’s 2017 fiscal year. Early adoption is permitted. The Company is evaluating the impact of this guidance on the Company’s Consolidated Financial Statements. In March 2016, the FASB issued ASU 2016-07, Investments – Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting. This update requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The standard will be effective for the Company’s 2017 fiscal year. Early adoption is permitted. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This update requires that a lessee recognize leased assets with terms greater than 12 months on the balance sheet for the rights and obligations created by those leases. The standard will be effective for the Company’s 2019 fiscal year. Early adoption is permitted. The Company is evaluating the impact of this guidance on the Company’s Consolidated Financial Statements. In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. This update requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The standard will be effective for the Company’s 2017 fiscal year. Early adoption is permitted. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This update simplifies the measurement of inventory valuation at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The new inventory measurement requirements will be effective for the Company’s 2018 fiscal year and will replace the current inventory valuation guidance that requires the use of a lower of cost or market framework. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements. In April 2015, the FASB issued ASU 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. This update provides guidance about whether a cloud computing arrangement includes a software license. The update will be effective for the Company’s 2017 fiscal year. Early adoption is permitted. The update allows for the use of either a prospective or retrospective adoption approach. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements. In April 2015, the FASB issued ASU 2015-03, Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. This ASU requires entities to present debt issuance costs in the balance sheet as a direct deduction from the carrying amount of the corresponding debt liability, consistent with debt discounts. The update will be effective for the Company’s 2017 fiscal year. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements. In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis, which affects reporting organizations that are required to evaluate whether they should consolidate certain legal entities. The update will be effective for the Company’s 2017 fiscal year. Early adoption is permitted, including adoption in an interim period. The update allows for the use of either a full retrospective or a modified retrospective adoption approach. The adoption of this ASU is not expected to have a material effect on the Company’s Consolidated Financial Statements. In May 2014, the FASB issued ASU 2014-09: Revenue from Contracts with Customers (Topic 606) which supersedes virtually all existing revenue recognition guidance under U.S. GAAP. The update's core principle is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The update allows for the use of either the retrospective or modified retrospective approach of adoption. On July 9, 2015 the FASB approved a one year deferral of the effective date of the update. The update will be effective for the Company’s 2019 fiscal year. We have not yet selected a transition method and are currently evaluating the impact of this guidance on the Company’s Consolidated Financial Statements.
