Notes to Condensed Consolidated Financial Statements (Unaudited)

The condensed consolidated financial statements of II-VI Incorporated ("II-VI", the "Company", "we", "us" or "our") for the three and six months ended December 31, 2017 and 2016 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, 2017. The consolidated results of operations for the three and six months ended December 31, 2017 are not necessarily indicative of the results to be expected for the full fiscal year. The June 30, 2017 Condensed Consolidated Balance Sheet information was derived from the Company's audited financial statements.

Adopted Pronouncements

In May 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. ASU 2017-09 provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. This ASU does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions, or award classification and would not be required if the changes are considered non-substantive. The new guidance is applied prospectively to awards modified on or after the adoption date. The adoption of this standard did not have a material effect on the Company's Consolidated Financial Statements.

In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment. This standard removes the second step of the goodwill impairment test, where a determination of the fair value of individual assets and liabilities of a reporting unit were needed to measure the goodwill impairment. Under this updated standard, goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The Company has adopted this standard for any impairment test that is performed after July 1, 2017 as permitted under the standard.

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. Under this ASU, excess tax benefits or deficiencies are recognized in income tax expense in the Condensed Consolidated Statement of Earnings. Upon adoption of this ASU, the Company had a valuation allowance for its U.S. deferred tax assets and did not recognize any tax benefit. Had the Company not had a valuation allowance, the Company would have recognized a tax benefit of $2.4 million. The impact to the Company's dilutive shares under this new standard was immaterial.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825). This update requires that public entities measure equity investments with readily determinable fair values, at fair value, with changes in their fair value recorded through net income. This ASU also clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entity's other deferred tax assets. The adoption of this standard did not 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 adoption of this standard did not have a material effect 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 eliminates the requirement to retrospectively apply the equity method in previous periods when an investor obtains significant influence over an investee. The adoption of this standard did not have a material effect on the Company's Consolidated Financial Statements.

Revenue Recognition Pronouncement Currently Under Evaluation

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. The update will be effective for the Company's 2019 fiscal year (July 1, 2018).

We continue our evaluation of the impact of the ASU in fiscal 2018 by evaluating its impact on selected contracts at each of our business segments.  As the ASU will supersede all existing revenue guidance affecting U.S. GAAP, it could impact revenue and cost recognition on our contracts across all our business segments, as well as our business processes and our information technology.  As a result, our evaluation of the effect of the ASU will continue through fiscal year 2018. The Company has completed its assessment of its military related contracts that comprise approximately 10% of consolidated revenues and preliminarily concluded that the Company will accelerate the recognition of revenue under the ASU for these contracts as the customer obtains control of the goods or service promised in the contract. The Company is currently evaluating the commercial portion of its business; the assessment will be completed during fiscal year 2018. Based upon our evaluation to date, we cannot currently estimate the impacts of adopting the ASU at this time. The Company will adopt this ASU using the modified retrospective method whereby the cumulative effect of applying the ASU would be recognized at the beginning of the year of adoption.

Other Pronouncements Currently Under Evaluation

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The standard will be effective for the Company's 2019 fiscal year. The adoption of this ASU is not expected to have a material effect on the Company's Consolidated Financial Statements.

In March 2017, the FASB issued ASU 2017-07, Compensation (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This update affects employers' presentation of defined benefit retirement plan costs. Early adoption is permitted. The standard will be effective for the Company's 2019 fiscal year. The adoption of this ASU is not expected to have a material effect on the Company's Consolidated Financial Statements.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. This update changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. Early adoption is permitted. The standard will be effective for the Company's 2019 fiscal year. The adoption of this ASU is not expected to have a material effect on the Company's Consolidated Financial Statements.

In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. This update requires that when intra-entity asset transfers occur, the entity must recognize tax effects in the period in which the transfer occurs. The standard will be effective for the Company's 2019 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 August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The guidance clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. The guidance also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flow. The update 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 June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This update is intended to provide financial statement users with more decision-useful information about expected credit losses and other commitments to extend credit held by the reporting entity. The standard replaces the incurred loss impairment methodology in current GAAP with one that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The update will be effective for the Company's 2021 fiscal year. Early adoption is permitted. The Company is evaluating the impact of this guidance on the Company's Consolidated Financial Statements.

10

I n 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 2020 fiscal year. Early adoption is permitted. The Company is evaluating the impact of this guidance on the Company's Consolidated Financial Statements.

Purchase of Equity Investment

In November 2017, the Company acquired a 93.8% equity investment in a privately-held company for $51.5 million. The Company's pro-rata share of earnings from this investment since the acquisition date was $1.1 million, and was recorded in other expense (income), net for the three and six months ended December 31, 2017, in the Consolidated Statements of Earnings.

The Company has a nonconsolidated investment that is accounted for under the equity method of accounting ("Equity Investment"). The following table summarizes the Company's equity in the nonconsolidated investment:

The Equity Investment has been determined to be a variable interest entity because the Company has an overall 93.8% economic position in the investee comprising a significant portion of its capitalization, but has only a 25% voting interest. The Company's obligation to receive rewards and absorb expected losses is disproportionate to its voting interest. The Company is not the primary beneficiary because it does not have the power to direct the activities of the equity investment that most significantly impact its economic performance. Certain business decisions, including, but not limited to, decisions with respect to operating  budgets, material capital expenditures, indebtedness, significant acquisitions or dispositions, and strategic decisions, require the approval of owners holding a majority percentage in the Equity Investment. Beginning on the date it was acquired, the Company accounted for its interest as an equity method investment as the Company has the ability to exercise significant influence over operating and financial policies of the Equity Investment.

As of December 31, 2017, the Company's maximum financial statement exposure related to the Equity Investment was approximately $54.8 million, which is the investment balance on the Consolidated Balance Sheet as of December 31, 2017.

The Company has the right to purchase all of the outstanding interest of each of the minority equity holders and the minority equity holders have the right to cause the Company to purchase all of outstanding interest at any time on or after the third anniversary of the investment or earlier upon certain events. The purchase price is equal to the greater of: (a) (i) the product of the aggregate trailing 12-month revenues of the investment preceding the date of purchase, multiplied by (ii) a factor of 2.9 multiplied by (iii) a factor of 0.723, multiplied by (iv) the percentage interest owned by each minority equity holder and (b) $966,666. The Company performed a Monte Carlo simulation to estimate the fair value of the net put option at the investment date and recorded a liability of $2.2 million in other long-term liabilities in the Condensed Consolidated Balance Sheet at December 31, 2017 in accordance with ASC 815-10, Derivatives and Hedging. The fair value of the net put option will be adjusted on a quarterly basis with any changes in the fair value recorded through earnings.

Kaiam Laser Limited, Inc.

In August 2017, the Company acquired Kaiam Laser Limited, Inc. ("Kaiam") a privately held company based in Newton Aycliffe, United Kingdom. Under the terms of the merger agreement, the consideration consisted of cash paid at the acquisition date of $79.5 million, net of cash acquired. The acquisition of Kaiam provides the Company with a 150mm wafer fabrication platform to significantly expand the Company's capacity for the production of vertical cavity surface emitting lasers ("VCSELs") for the 3D sensing market and broadens the capability to address new market opportunities in other compound semiconductor materials. Kaiam now operates under the name II-VI Compound Semiconductor Ltd. within the Company's II-VI Laser Solutions operating segment. Due to the timing of the acquisition, the Company is still in the process of measuring the fair value of assets acquired, including tangible, intangible assets and related deferred income taxes.

Integrated Photonics, Inc.

In June 2017, the Company acquired Integrated Photonics, Inc. ("IPI"), a privately held company based in New Jersey. IPI is a leader in engineered magneto-optic materials that enable high-performance directional components such as optical isolators for the optical communications market. Under the terms of the merger agreement, the consideration consisted of initial cash paid at the acquisition date of $40.1 million, net of cash acquired and a working capital adjustment of $0.8 million. In addition, the agreement provides up to a maximum of $2.5 million of additional cash earnout opportunities based upon IPI achieving certain agreed upon financial and transitional objectives, which if earned would be payable in the amount of $2.5 million for the achievement of the annual target.

The following table presents the preliminary purchase price at the date of acquisition ($000):

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 valuation of property, plant and equipment, identifiable intangibles and deferred income tax liabilities and anticipates completion of the valuation within one year from the date of the acquisition ($000):

The goodwill of $17.5 million is included in the II-VI Photonics segment and is attributed to the expected synergies and the assembled workforce of IPI. 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 Company expensed transaction costs of $0.3 million all within the year ended June 30, 2017.

The amount of revenues of IPI included in the Company's Consolidated Statement of Earnings for the three and six months ended December 31, 2017 was $4.9 million and $10.3 million, respectively. The amount of net earnings of IPI included in the Company's Consolidated Statement of Earnings for the three and six months ended December 31, 2017 was $1.0 million and $1.4 million, respectively.

In conjunction with the acquisition of II-VI Compound Semiconductors Ltd., the Company recorded $0.4 million attributed to the value of technology and patents and $3.6 million of customer lists. The intangibles were recorded based on the Company's preliminary purchase price allocation utilizing either a discounted cash flow or relief from royalty method to derive the fair value. The valuation is expected to be finalized within one year from the date of acquisition.

14

Technology and patents are being amortized over a range of 60 to 240 months, with a weighted ave rage remaining life of approximately 95 months. Customer lists are being amortized over a range of approximately 120 to 240 months with a weighted average remaining life of approximately 144 months.

Included in the gross carrying amount and accumulated amortization of the Company's intangible as sets is the effect of foreign currency translation on that portion of the intangible assets relating to the Company's German, U.K. and Chinese subsidiaries.

At December 31, 2017, the estimated amortization expense for the existing intangible assets for each of the five succeeding fiscal years is as follows ($000):

0.25% Convertible Senior Notes

On August 24, 2017, the Company entered into a purchase agreement with Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representatives of the several initial purchasers named therein (collectively, the "Initial Purchasers"), to issue and sell $300 million aggregate principal amount of our 0.25% convertible senior notes due 2022 (the "Notes") in a private placement to qualified institutional buyers within the meaning of Rule 144A under the Securities Act of 1933, as amended. In addition, we granted the Initial Purchasers a 30-day option to purchase up to an additional $45 million aggregate principal amount of the Notes (the "Over-Allotment Option").

On August 29, 2017, the Initial Purchasers exercised their Over-Allotment Option to purchase the entire $45 million in aggregate principal amount of additional Notes. The Notes mature on September 1, 2022, unless earlier repurchased by the Company or converted by holders in accordance with the terms of the Notes. Interest is payable semi-annually in arrears on March 1 and September 1 of each year, beginning on March 1, 2018.

The sale of the Notes to the Initial Purchasers settled on August 29, 2017, and resulted in approximately $336 million in net proceeds to the Company after deducting the initial purchasers' discount and the estimated offering expenses. The net proceeds from the offering and sale of the Notes were used, in part, to repurchase approximately $49.9 million of our Common Stock.  The Company used the remaining net proceeds to repay $252 million on its revolving credit facility and to pay debt issuance costs of $10.1 million.

15

The Notes are governed by an Indenture between the Company, as issuer, and U.S. Bank, National Association, as trustee. The Notes will be our senior unsecured obligations and rank senior in right of payme nt to any of our indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of our indebtedness that is not so subordinated; effectively junior in right of payment to any of our secured indebtedness to th e extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries. In the event of our bankruptcy, liquidation, reorganization or other winding u p, our assets that secure secured debt will be available to pay obligations on the Notes only after all indebtedness under such secured debt has been repaid in full from such assets. Upon conversion, the Company will pay or deliver, as the case may be, cas h, shares of our Common Stock or a combination of cash and shares of our Common Stock, at the Company's election.

As a result of our cash conversion option, the Company separately accounted for the value of the embedded conversion option as a debt discount. The value of the embedded conversion option was determined based on the estimated fair value of the debt without the conversion feature, which was determined using an expected present value technique (income approach) to estimate the fair value of similar nonconvertible debt; the debt discount is being amortized as additional non-cash interest expense over the term of the Notes using the effective interest method with an effective interest rate of 4.5% per annum.

The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The initial conversion rate is 21.25 shares of Common Stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of $47.06 per share of Common Stock. Throughout the term of the Notes, the conversion rate may be adjusted upon the occurrence of certain events.

Holders of the Notes will not receive any cash payment representing accrued and unpaid interest upon conversion of a note. Accrued but unpaid interest will be deemed to be paid in full upon conversion rather than cancelled, extinguished or forfeited.

Prior to the close of business on the business day immediately preceding June 1, 2022, the Notes will be convertible only upon satisfaction of at least one of the conditions as follows:

On or after June 1, 2022 until the close of business on the business day immediately preceding the maturity date, holders may convert all or any portion of their Notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances.

As of  December 31, 2017, the Notes are not yet convertible. In accounting for the transaction costs related to the Note issuance, the Company allocated the total amount of offering costs incurred to the debt and equity components based on their relative values. Offering costs attributable to the debt component, totaling $8.4 million, are being amortized as non-cash interest expense over the term of the Notes, and offering costs attributable to the equity component, totaling $1.7 million, were recorded within stockholders' equity.

The following table sets forth total interest expense recognized related to the Notes for the three and six months ended December 31, 2017:

Amended Credit Facility

On July 28, 2016, the Company amended and restated its existing credit agreement. The Third Amended and Restated Credit Agreement (the "Amended Credit Facility") provides for a revolving credit facility of $325 million, as well as a $100 million term loan. 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, 2016, 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 July 27, 2021. Amounts borrowed under the revolving credit facility are due and payable on the maturity date. The Amended 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 Amended Credit Facility has a five-year term through July 27, 2021 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 Amended Credit Facility. If the Base Rate option is selected for a borrowing, the Applicable Margin is 0.00% to 1.25% and if the Euro-Rate Option is selected for a borrowing, the Applicable Margin is 1.00% to 2.25%. The Applicable Margin is based on the ratio of the Company's 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 December 31, 2017, the Company was in compliance with all financial covenants under its Amended Credit Facility.

Yen Loan

The Company's Yen denominated line of credit is a 500 million Yen (approximately $4.4 million) facility. The Yen line of credit matures in August 2020. The interest rate is equal to LIBOR, as defined in the loan agreement, plus 0.625% to 1.75%. At December 31, 2017 and June 30, 2017, the Company had 300 million Yen borrowed. Additionally, the facility is subject to certain covenants, including those relating to minimum interest coverage and maximum leverage ratios. As of December 31, 2017, the Company was in compliance with all financial covenants under its Yen facility.

Note Payable

In conjunction with the acquisition of IPI, the Company assumed a non-interest bearing note payable owed to a major customer of IPI. The agreement if not terminated early by either party is payable in full in May 2019.

Aggregate Availability

The Company had aggregate availability of $225.6 million and $73.5 million under its lines of credit as of December 31, 2017 and June 30, 2017, respectively. The amounts available under the Company's lines of credit are reduced by outstanding letters of credit. As of December 31, 2017 and June 30, 2017, total outstanding letters of credit supported by these credit facilities were $1.2 million for both periods.

Weighted Average Interest Rate

The weighted average interest rate of total borrowings was 1.4% and 2.1% for the six months ended December 31, 2017 and 2016, respectively.

Remaining Annual Principal Payments

Remaining annual principal payments under the Company's existing credit obligations from December 31, 2017 were as follows:

17

The Company's year-to-date effective income tax rate at December 31, 2017 and 2016 was 45.9% and 27.8%, respectively. The variations between the Company's effective tax rate and the U.S. statutory rate of 28% for our fiscal year ending June 30, 2018 were primarily due to the impact of the U.S. enacted tax legislation and earnings generated from the Company's foreign operations, which are subject to income taxes at lower statutory rates.  

U.S. GAAP prescribes the accounting for uncertainty in income taxes recognized in an enterprise's financial statements which includes 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 December 31, 2017 and June 30, 2017, the Company's gross unrecognized income tax benefit was $7.7 million and $7.6 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, $5.5 million of the gross unrecognized tax benefits at December 31, 2017 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 gross unrecognized income tax benefit was $0.5 million and $0.3 million, at December 31, 2017 and June 30, 2017, respectively. Fiscal years 2014 to 2018 remain open to examination by the United States Internal Revenue Service, fiscal years 2012 to 2018 remain open to examination by certain state jurisdictions, and fiscal years 2006 to 2018 remain open to examination by certain foreign taxing jurisdictions. The Company's income tax returns are not currently under examination. The Company believes its income tax reserves for these tax matters are adequate.

U.S. Tax Reform

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "Tax Act"). The Tax Act significantly revises the future ongoing U.S. corporate income tax by, among other things, lowering U.S. corporate income tax rates and implementing a territorial tax system. As the Company has a June 30 fiscal year-end, the lower corporate income tax rate will be phased in, resulting in a U.S. statutory federal rate of approximately 28% for the Company's fiscal year ending June 30, 2018, and 21% for subsequent fiscal years.  As part of the transition to the new territorial tax system, the Tax Act imposes a one-time repatriation tax on total post-1986 earnings and profits ("E&P") of foreign subsidiaries that were previously deferred from U.S. income taxes.

At December 31, 2017, the Company has not finalized its accounting for the tax effects of the Tax Act; however, as described below, management has made a reasonable estimate of the effects on existing deferred tax balances and has recorded an estimated amount for its one-time repatriation tax, resulting in an increase in income tax expense. The Company has yet to complete its calculation of the total post-1986 foreign E&P. Further, the one-time repatriation tax is based in part on the amount of those earnings held in cash and other specified assets and could be impacted by the balance of those assets at June 30, 2018, which is not yet known. This amount may change when the Company finalizes the calculation of post-1986 foreign E&P previously deferred from U.S. taxation and the amounts held in cash or other specified assets as of June 30, 2018 are known.

The impact of the repatriation tax is expected to be offset by available net operating loss and credit carryforwards which currently have a valuation allowance.  Thus the tax expense reported is reduced by the release of the valuation allowance on U.S. deferred tax assets.  The reduction of the U.S. corporate tax rate caused the Company to adjust the U.S. deferred tax assets and liabilities to the lower U.S. statutory federal rate of 21%. However, the Company will continue to analyze certain aspects of the Tax Act which could affect the measurement of these balances or give rise to new deferred tax amounts. In addition, the Company has recorded withholding taxes on planned repatriation due to the change to a territorial tax system.  The transitional impacts described above resulted in a cumulative provisional net charge of $15.8 million for the quarter ended December 31, 2017.  

The changes included in the Tax Act are broad and complex. The final transition impacts of the Tax Act may differ from the estimates recorded during the quarter ended December 31, 2017, possibly materially, due to, among other things, changes in interpretations of the Tax Act, any legislative action to address questions that arise because of the Tax Act, any changes in accounting standards for income taxes or related interpretations in response to the Tax Act, or any updates or changes to estimates the Company has utilized to calculate the transition impacts, including impacts from changes to current year earnings estimates and foreign exchange rates of foreign subsidiaries. The Securities Exchange Commission has issued rules that allow for a measurement period of up to one year after the enactment date of the Tax Act to finalize the recording of the related tax impacts. The Company currently anticipates finalizing and recording any resulting adjustments by the end of the quarter ending December 31, 2018.

The following table sets forth the computation of earnings per share for the periods indicated. Weighted average shares issuable upon the exercises of stock options and the release of performance and restricted shares are not included in the calculation because they were anti-dilutive and totaled approximately 133,000 and 110,000 for the three and six months ended December 31, 2017, respectively, and 86,000 and 227,000 for the three and six months ended December 31,2016, respectively. The earnings per share computation does not include the effects of the convertible note issuance as these notes were not convertible at December 31, 2017, ($000 except per share data):

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.

In June 2017, the Company completed its acquisition of IPI. See Note 3. Acquisitions and Investment. The operating results of this acquisition have been reflected in the selected financial information of the Company's II-VI Photonics segment since the date of acquisition.

In August 2017, the Company completed its acquisition of II-VI Compound Semiconductor Ltd. See Note 3. Acquisitions and Investment. The operating results of this acquisition have been reflected in the selected financial information of the Company's II-VI Laser Solutions segment since the date of acquisition.

The accounting policies of the segments are the same as those of the Company. The Company's corporate expenses and assets are allocated to the segments. The Company evaluates segment performance based upon reported segment operating income, which is defined as earnings before income taxes, interest and other income or expense. Inter-segment sales and transfers are eliminated.
