Total: | 11,443 | 100%

Manufacturing Processes

Our success in developing and manufacturing many of our products depends on our ability to manufacture and to tailor the optical and physical properties of technically-challenging materials and components. The ability to produce, process and refine these complex materials and to control their quality and in-process yields is an expertise of the Company that is critical to the performance of our customers’ instruments and systems. In the markets we serve, there are a limited number of high-quality suppliers of many of the components we manufacture and there are very few industry-standard products.

Our network of worldwide manufacturing sites allows us to manufacture our products in regions that provide cost-effective advantages. We employ numerous advanced manufacturing technologies and systems at our manufacturing facilities. These include metal organic chemical vapor deposition and molecular beam epitaxy reactors, automated Computer Numeric Control optical fabrication, high throughput thin-film coaters, nano-precision metrology and custom-engineered automated furnace controls for crystal growth processes. Manufacturing products for use across the electro-magnetic spectrum requires the capability to repeatedly produce products with high yields to atomic tolerances. II-VI continuously updates its comprehensive quality management systems that feature manufacturing quality best practices. II-VI is committed to delivering products within specification, on time and with high quality, with a goal of fully satisfying customers and continually improving.

5

Sources of Supply

Among the major feed stock and raw materials we use include zinc, selenium, ZnSe, ZnS, hydrogen selenide, hydrogen sulfide, tellurium, yttrium oxide, aluminum oxide, iridium, platinum, bismuth, silicon, thorium fluoride, antimony, carbon, graphite, GaAs, InP, copper, germanium, molybdenum, quartz, optical glass, diamond, and other materials.

The continued high-quality of and access to these materials is critical to the stability and predictability of our manufacturing yields. We test materials at the onset and throughout the production process. Additional research and capital investment may be needed to better define future material specifications. We have not experienced significant production delays due to shortages of materials. However, we do occasionally experience problems associated with vendor-supplied materials not meeting contract specifications for quality or purity. As discussed in greater detail in Item 1A – Risk Factors, of this Annual Report on Form 10-K, significant failure of our suppliers to deliver sufficient quantities of necessary high-quality materials to our specifications on a timely basis could have a materially adverse effect on our results of our operations.

Our Markets

Our market-focused businesses are organized by technology and products. Our businesses are composed of the following primary markets: Communications, Materials Processing, Military, Semiconductor Equipment, Life Sciences, Consumer Electronics and Automotive.

Communications Market

II-VI’s optical communications products and technologies enable the next generation of high-speed optical transmission systems, networks, and datacenter solutions necessary to meet the accelerating global bandwidth demand. At the core of both terrestrial and undersea optical networks, our market-leading 980 nm pump lasers boost the power of the optical signal in the fiber optic cable at intervals along the way to enable a larger number of high speed signals to be transmitted over longer distances. Our latest generation of 980 nm pump lasers along with miniature tunable filters and hybrid passives are part of our ultra-compact family of components critical to a new generation of small size, long reach DWDM transmission modules operating at 100, 200 and 400 Gb/s.

Customers continue to rely on us for our industry-leading optical amplification and embedded monitoring solutions for their next generation ROADM systems to compensate for the inherent signal loss and to monitor the signal integrity. Our proprietary OTDR modules allow systems to automatically detect and pinpoint issues along the transmission path in real time. The accelerating adoption of applications such as cloud computing are driving the rapid growth of datacenter buildouts. Our high-speed 25 Gb/s VCSELs enable intra-datacenter transceivers to transmit and receive signals. Our miniature WDM thin film filter assemblies are used to increase the bandwidth within 100 GbE transceivers by combining wavelengths at the transmitter end and separating them out at the receiver end.

In mobile wireless applications, II-VI supplies base SiC substrates to customers who manufacture RF power amplifier devices that are embedded in remote radio heads in 4G wireless bases stations to boost the power of RF signal before it reaches the antenna. These devices are also widely expected to be embedded in next generation active antennas for 5G wireless, where multiple devices per antenna will be required to enable higher bandwidth. SiC has a high number of intrinsic physical and electronic advantages, such as high thermal conductivity, that enable them to operate at high-power levels and still dissipate the excess heat generated.

Materials Processing Market

Our industrial laser optics and solutions for the materials processing market remain in strong demand. There continues to be a steady global demand to support existing installations and new deployments of CO2 and fiber laser systems. Our vertically integrated and market leading ZnSe optics and components, due to their inherent low loss at around 10 micron wavelength, have enabled high-power CO2 laser systems for many decades and remain critical to the steady stream of new deployments as well as to continued operation, serving as replacement optics, of the installed base of CO2 lasers. II-VI continues to introduce products that address new and growing applications for low-power CO2 lasers, such as cutting textiles, leather, wood and other organic materials, for which the CO2 laser’s 10 micron wavelength is ideally suited. CO2 lasers are also at the core of EUV lithography systems, which are now emerging on the market to enable a new generation of smaller and more powerful personal integrated circuits for the internet of things computing devices.

Over the past several years, fiber laser-based systems operating at one micron wavelength in pulsed or continuous mode have taken a central role in nearly all materials processing segments, and especially for precision machining such as marking and micro drilling. From the laser chips that generate the input optical power to the beam delivery systems that direct the output optical power to the target, II-VI supplies a broad set of laser optics and fused fiber products that enable many functions within these systems. The same set of II-VI products is also at the core of existing and emerging direct diode laser systems. II-VI is also driving innovation with a direct-diode laser engine small enough to be mounted on a robotic arm so that the end user can apply square beams directly to the work piece at wavelengths optimized for aluminum processing.

Another emerging and fast growing application is the processing of displays for consumer electronics, including those based on the OLED technology that are scribed with CO lasers and sealed with UV lasers. II-VI’s broad portfolio of coated optics and crystal materials serve all of these growing laser markets.

Military Market

Our focus in the military market is enabling lasers for targeting, night vision, navigation, as well as intelligence, surveillance and reconnaissance systems. Multiple fighter jets are equipped with our large area sapphire windows that surround advanced electro-optical targeting and imaging systems. Infrared domes are used on missiles with infrared guidance systems ranging from small, human-portable designs to larger designs mounted on helicopters, fixed-wing aircraft and ground vehicles. High-precision domes are an integral component of a missile’s targeting system, providing efficient tactical capability, while serving as a protective cover to its internal components.

9

Rotary and fixed-wing aircraft also use missile warning systems to protect against shoulder fired human-portable missiles. Our competencies in material growth for UV crystals and our optical assembly capabilitie s provide significant support to these missile warning systems. A key attribute of several of these systems is the ability to filter electro-magnetic interference using micro-fine conductive mesh patterns. This technology is also applied to non-optical app lications for absorbing and transmitting energy from the surfaces of aircraft and missiles.

Many military systems employ laser designation and range-finding capabilities supported by our semiconductor lasers bars and solid state laser host crystals and laser optics, all manufactured in-house, as well as our competency in short wave infrared and visible optics. Our thermoelectric coolers are used to increase thermal imaging sensitivity, or to maintain a constant window temperature in various visible and infrared applications.

We provide a range of battlefield-ready technologies for soldier equipment and specifically designed variants for law enforcement. Our precision patterned reticles are embedded in rifle scopes. Our reaction bonded boron carbide materials are shaped into torso plates and employed as in-aircraft cabin and protective body armor. Our thermo-electric coolers are used to regulate the soldier’s body heat. They are also used to convert heat produced by battlefield fuel burners into electrical power, for example to extend battery life on the battlefield.

We maintain engineering and manufacturing facilities in the United States with strictly controlled access that are dedicated to our U.S. government supported contracts.

Semiconductor Capital Equipment Market

Semiconductor equipment requires advanced materials to meet the need for tighter tolerances, enhanced thermal stability, faster wafer transfer speeds and reduced stage settling times. Our metal matrix composites and reaction bonded ceramics enable these applications thanks to their optimum combination of light weight, strength, hardness and coefficient of thermal expansion. Our reaction bonded SiC materials are used to manufacture wafer chucks, light weight scanning stages and high temperature, corrosion resistant wafer support systems. Our cooled SiC mirrors and precision patterned reticles are used in the illumination systems of lithography tools.

In the emerging market of EUV lithography systems, CO2 lasers are used to generate extreme ultraviolet light. These CO2 lasers and beam delivery systems leverage our broad portfolio of CO2 laser optics, CdTe Modulators, high power damage resistant polycrystalline CVD diamond windows to route the powerful laser beam to a tin droplet from which EUV light will emanate. Due to their very high mechanical and thermal performance characteristics, our reaction bonded SiC are used in structural support systems that are integral to EUV lithography optics to meet critical requirements for optical system stability.

Life Sciences Market

The majority of our business in the life sciences end market is in analytical tools. Many analytical tools found in modern biotech laboratories are based on some form of interaction with light. This applies to flow cytometry, cell sorting, confocal microscopy, DNA genome sequencing, Raman spectroscopy, fluorescence spectroscopy and particle sizing to name a few. Our multi-colored laser engines along with our broad portfolio of application-specific optics, filters and gratings are embedded in these analytical tools. We also supply objective lenses, precision patterned reticles and assemblies for microscopes.

Genome sequencing involves temperature cycling DNA in flow cells with a high degree of temperature uniformity and precision. We believe that our thermal engines are the state of the art in chiller technology, and they achieve what we believe to be industry-leading temperature control and uniformity across large areas. Our green lasers are used to excite the fluorescence of DNA to reveal its structure. Our flow cells are micro-machined with a high degree of precision to insure the smooth flow of sample fluids undergoing analysis. Our thermal engines are also used in a multitude of other biomedical applications, for example to measure substance concentration in complex mixtures, to protect blood supplies and to perform heating- and cooling-based physical therapy.

Clinical procedures are increasingly performed with tools that embed our lasers and optics. For example, our semiconductor laser bars are used in hair and wrinkle removal procedures and our custom designed lens assemblies are used for laser eye surgery. We continue to leverage our core lasers, optics and temperature control expertise into new applications to grow our business in life sciences.

Consumer Electronics Market

II-VI manufactures low cost VCSELs, VCSEL arrays and low angle shift filters for the consumer electronics market. Our VCSEL products leverage our world-class 6-inch GaAs platform, combining our epitaxial wafer growth and wafer fabrication capabilities.

10

Our VCSELs, unlike many on the market, have already been designed into consumer products such as the computer mouse as well as for menu navigation in smart phones and in car steering wheels. Our VCSELs are also widely deployed in datacenters and in the eme rging market for HDMI optical cables. This expertise in VCSEL technology is being leveraged for the emerging 3D sensing market. With our acquisitions of 6-inch epitaxy and wafer capabilities, we have invested significantly to round out our capacity expansi on.

Automotive Market

Power conversion electronics for high-efficiency electric vehicles need a combination of high-power density, high-efficiency and high-temperature operation that are only afforded by advanced material systems based on SiC substrates. Our SiC substrates are available in large diameters and have what we believe to be best-in-class quality and low defect levels.

Our thermoelectric modules are used to cool batteries to extend their operating life. They are also more efficient than resistive heaters when used in heated car seats and extend an electric vehicle’s range of travel in cold environments.

To operate safely, self-driving cars will rely on control systems that are informed by a comprehensive number of sensors. One such sensor is based on LiDAR, which employs semiconductor lasers to properly identify and measure the distance to obstacles ahead. Our GaAs-based semiconductor laser platform, which already enables a broad portfolio of products in communications and materials processing, is now being scaled further for consumer electronics, and will be leveraged to deliver a highly reliable and cost-effective laser product for this emerging market.

Marketing and Sales

Research, Development and Engineering

During the fiscal year ended June 30, 2018, the Company continued to identify, invest in and focus our research and development on, new products in an effort to accelerate our organic growth. This approach is managed under a disciplined innovation program that we refer to as the “II-VI Phase Gate Process.”

From time to time, the ratio of externally funded contract activity to internally funded contract activity varies due to the unevenness of government funded research programs and changes in the focus of our internally funded research programs. We are committed to having the right mix of internally and externally funded research that ties closely to our long-term strategic objectives.

We devote significant resources to RD&E programs directed at the continuous improvement of our existing products and processes and to the timely development of new technologies, materials and products. We believe that our RD&E activities are essential to establish and maintain a leadership position in each of the markets we serve. As of June 30, 2018, we employed 1,513 people in RD&E functions, 1,439 of whom are engineers or scientists. In addition, certain manufacturing personnel support or participate in our research and development efforts on an ongoing basis. We believe this interaction between the development and manufacturing functions enhances the direction of our projects, reducing costs and accelerating technology transfers.

We have entered into selective intellectual property licensing agreements. We have asserted in the past, and expect that we will continue to assert and vigorously protect our intellectual property rights. We have a total of approximately 800 patents globally.

Internally funded research and development expenditures were $117.2 million, $96.8 million and $60.4 million for the fiscal years ended June 30, 2018, 2017 and 2016, respectively. For these same periods, externally funded research and development expenditures were $12.7 million, $8.7 million and $9.5 million, respectively and were included in Cost of goods sold in the Consolidated Statements of Earnings.

15

Export and Import Compliance

We are required to comply with various export/import control and economic sanction laws, including:

| • | The International Traffic in Arms Regulations administered by the U.S. Department of State, Directorate of Defense Trade Controls, which, among other things, impose licensing requirements on the export from the United States of certain defense articles and defense services, which generally include items that are specially designed or adapted for a military application and/or listed on the U.S. Munitions List;

| • | The Export Administration Regulations administered by the U.S. Department of Commerce, Bureau of Industry and Security, which, among other things, impose licensing requirements on certain dual-use goods, technology and software, which are items that potentially have both commercial and military applications;

| • | The regulations administered by the U.S. Department of Treasury, Office of Foreign Assets Control, which implement economic sanctions imposed against designated countries, governments and persons based on U.S. foreign policy and national security considerations; and

| • | The import regulations administered by the U.S. Customs and Border Protection.

Foreign governments have also implemented similar export and import control regulations, which may affect our operations or transactions subject to their jurisdiction. For additional discussions regarding our import and export compliance, see the discussion set forth in Item 1A – Risk Factors of this Annual Report Form on Form 10-K.

Trade Secrets, Patents and Trademarks

Our use of trade secrets, proprietary know-how, trademarks, copyrights, patents and contractual confidentiality and IP ownership provisions help us develop and maintain our competitive position with respect to our products and manufacturing processes. We aggressively pursue process and product patents in certain areas of our businesses. We have entered into selective intellectual property licensing agreements. We have confidentiality and non-competition agreements with certain personnel. We require that our U.S. employees sign a confidentiality and non-competition agreement upon their commencement of employment with us.

The design, processes and specialized equipment utilized in our engineered materials, advanced components and subsystems are innovative, complex and difficult to duplicate. However, there can be no assurance that others will not develop or patent similar technology, or that all aspects of our proprietary technology will be protected. Others have obtained patents covering a variety of materials, devices, equipment, configurations and processes, and others could obtain patents covering technology similar to ours. We may be required to obtain licenses under such patents, and there can be no assurance that we would be able to obtain such licenses, if required, on commercially reasonable terms, or that claims regarding rights to technology will not be asserted that may adversely affect our results of operations. In addition, our research and development contracts with agencies of the U.S. Government present a risk that project-specific technology could be disclosed to competitors as contract reporting requirements are fulfilled.

Item 1A. | RISK FACTORS

We caution our investors that our performance is subject to risks and uncertainties. The following material risk factors may cause our future results to differ materially from those projected in any forward-looking statement. You should carefully consider these factors, as well as the other information contained in this Annual Report on Form 10-K when evaluating an investment in our securities.

Investments in Future Markets of Potential Significant Growth May Not Result in Expected Returns

We have initiated investment programs with the goal of gaining a greater share of end markets using semiconductor lasers and other components including those used for 3D sensing. We cannot guarantee that our investments in capital and capabilities will be sufficient. The potential end markets, as well as our ability to gain market share in such markets, may not materialize on the timeline anticipated or at all. We cannot be sure of the end market price, specification or yield for products incorporating our technologies. Our technologies could fail to fulfill, partially or completely our target customers’ finalized specifications. We cannot guarantee the end market customers’ acceptance of our technologies. Further, we may be unable to fulfill the terms of our contracts with our target customers, which could result in penalties of a material nature, including consequential damages, loss of market share and loss of reputation.

Our Competitive Position Depends on Our Ability to Develop New Products and Processes

To meet our strategic objectives, we must develop, manufacture and market new products and continue to update our existing products and processes to keep pace with market developments to address increasingly sophisticated customer requirements. Our success in developing and selling new and enhanced products and processes depends upon a variety of factors including strategic product selection, efficient completion of product design and development, timely implementation of manufacturing and assembly processes, effective sales and marketing, high-quality and successful product performance in the market.

The introduction by our competitors of products or processes using new developments better or faster than ours could render our products or processes obsolete or unmarketable. We intend to continue to make significant investments in RD&E to achieve our goals. There can be no assurance that we will be able to develop and introduce new products or enhancements to our existing products and processes in a manner which satisfies customer needs or achieves market acceptance. The failure to do so could have a material adverse effect on our ability to grow our business and maintain our competitive position and on our results of operations and/or financial condition.

Our Competitive Position May Still Require Significant Investments

We continuously monitor the marketplace for strategic opportunities, and our business strategy includes expanding our product lines and markets through both internal product development and acquisitions. Consequently, we expect to continue to consider strategic acquisition of businesses, products or technologies complementary to our business. This may require significant investments of management time and financial resources. If market demand is outside our organic capabilities, if a strategic acquisition is required and we cannot identify one or execute on it, and/or if financial investments that we undertake distract management, do not result in the expected return on investment, expose us to unforeseen liabilities or jeopardize our ability to comply with our credit facility covenants due to any inability to integrate the business, adjust to operating a larger and more complex organization, adapt to additional political and other requirements associated with the acquired business, retain staff, or work with the customers or otherwise we could suffer a material adverse effect on our business, results of operations or financial condition.

Our Future Success Depends on Continued International Sales, and Our Global Operations are Complex, and Present Multiple Challenges to Manage

Sales to customers in countries other than the United States accounted for approximately 68%, 69% and 63% of revenues during the years ended June 30, 2018, 2017 and 2016, respectively. We anticipate that international sales will continue to account for a significant portion of our revenues for the foreseeable future. If we do not maintain our current volume of international sales, we could suffer a material adverse effect on our business, results of operations and/or financial condition.

We manufacture products in the United States, China, Singapore, Vietnam, the Philippines, Germany, Switzerland, and the United Kingdom and through a contract manufacturer in Thailand. We also maintain direct sales offices in Hong Kong, Japan, Germany, China, Switzerland, Belgium, the United Kingdom, China, Italy, South Korea, and Taiwan. Our operations vary by location and are influenced on a location-by-location basis by local customs, languages and work practices, as well as different local weather conditions, management styles and education systems. In addition, multiple complex issues may arise concurrently in different countries, potentially hampering our management’s ability to respond in an effective and timely manner. Any inability to respond in an effective and timely manner to issues in our global operations could have a material adverse effect on our business, results of operations or financial condition.

18

Foreign Currency Risk May N egatively Affect our Revenues, Cost of Sales and Operating Margins and Could Result in Foreign Exchange Losses

We conduct our business and incur costs in the local currency of most countries in which we operate. Our net sales outside the United States represented a majority of our total sales in each of the last three fiscal years. We incur currency transaction risk whenever one of our operating subsidiaries enters into either a purchase or a sales transaction using a different currency from the currency in which it operates or holds assets or liabilities in a currency different than its functional currency. Changes in exchange rates can also affect our results of operations when the value of sales and expenses of foreign subsidiaries are translated to U.S. dollars. We cannot accurately predict the impact of future exchange rate fluctuations on our results of operations. Further, given the volatility of exchange rates, we may not be able to effectively manage our currency risks, and any volatility in currency exchange rates may increase the price of our products in local currency to our foreign customers or increase the manufacturing cost of our products, either of which may have an adverse effect on our financial condition, cash flows and profitability.

Any Inability to Access Financial Markets from Time to Time to Raise Required Capital, Finance Our Working Capital Requirements or Our Acquisition Strategies, or Otherwise to Support our Liquidity Needs Could Negatively Impact our Ability to Finance our Operations, Meet Certain Obligations or Implement our Growth Strategy

We occasionally borrow under our existing credit facilities to fund operations, including working capital investments, and to finance our acquisition strategies. In the past, market disruptions experienced in the United States and abroad have materially impacted liquidity in the credit and debt markets, making financing terms for borrowers less attractive, and, in certain cases, have resulted in the unavailability of certain types of financing. Uncertainty in the financial markets may negatively impact our ability to access additional financing or to refinance our existing credit facilities or existing debt arrangements on favorable terms or at all, which could negatively affect our ability to fund current and future expansion as well as future acquisitions and development. These disruptions may include turmoil in the financial services industry, volatility in the markets where our outstanding securities trade, and general economic downturns in the areas where we do business. If we are unable to access funds at competitive rates, or if our short-term or long-term borrowing costs increase, our ability to finance our operations, meet our short-term obligations and implement our operating strategies could be adversely affected.

In the future we may be required to raise additional capital through public or private financing or other arrangements. Such financing may not be available on acceptable terms, or at all, and our failure to raise capital when needed could harm our business and prospects. Additional equity financing may be dilutive to the holders of our common stock, and debt financing, if available, may involve restrictive covenants that may limit our ability to undertake certain operational activities that we otherwise would find to be desirable. Further, debt service obligations associated with any such debt financing could reduce our profitability. If we cannot raise funds on acceptable terms, we may not be able to grow our business or respond to competitive pressures.

We May Incur Substantially More Indebtedness

We and our subsidiaries may be able to incur substantial additional indebtedness in the future, including secured indebtedness, subject to the restrictions contained in our debt instruments. We are not restricted under the terms of the indenture governing our outstanding convertible senior notes from incurring additional indebtedness, securing existing or future indebtedness, recapitalizing our debt obligations or taking a number of other actions that are not limited by the terms of the indenture. Our credit facility currently restricts our ability to incur additional indebtedness, including secured indebtedness, but if our credit facility matures or is repaid, we may not be subject to such restrictions under the terms of any subsequent indebtedness.

We May Not Be Able to Settle Conversions of Our Convertible Senior Notes in Cash or to Repurchase the Notes in Accordance with Their Terms

Holders of our outstanding convertible senior notes have the right to require us to repurchase all or a portion of their notes upon the occurrence of a fundamental change (as defined in the indenture governing the notes) at a repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any. In addition, upon conversion of the notes, unless we elect to deliver solely shares of our common stock to settle such conversions (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the notes being converted. However, we may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of notes surrendered therefor or pay cash with respect to notes being converted.

In addition, our ability to repurchase or to pay cash upon conversion of the notes may be limited by law, regulatory authority or agreements governing our future indebtedness. Our failure to repurchase notes at a time when the repurchase is required by the governing indenture or to pay any cash upon conversion of the notes as required would constitute a default under the indenture. A default under the indenture or the fundamental change itself also could lead to a default under agreements governing our credit facility and any of our future indebtedness. If the payment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the notes or to pay cash upon conversion of the notes.

19

The Conditional Conversion Feature of Our Outstanding Convertible Senior Notes, if Triggered, May Adversely Affect Our Financial Condition and Operating Results

In the event the conditional conversion feature of the notes is triggered, holders of notes will be entitled to convert the notes at any time during specified periods at their option. If one or more holders elect to convert their notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity.

We May Fail to Accurately Estimate the Size and Growth of Our Markets and Our Customers’ Demands

We make significant decisions based on our estimates of customer requirements. We use our estimates to determine the levels of business we seek and accept, production schedules, personnel needs and other resource requirements.

Customers may require rapid increases in production on short notice. We may not be able to purchase sufficient supplies or allocate sufficient manufacturing capacity to meet such increases in demand. Rapid customer ramp-up and significant increases in demand may strain our resources or negatively affect our margins. Inability to satisfy customer demand in a timely manner may harm our reputation, reduce our other opportunities, damage our relationships with customers, reduce revenue growth, and/or incur contractual penalties.

Alternatively, downturns in the industries in which we compete may cause our customers to significantly reduce their demand. With respect to orders we initiate with our suppliers to address anticipated demand from our customers, certain suppliers may have required non-cancelable purchase commitments or advance payments from us, and those obligations and commitments could reduce our ability to adjust our inventory or expense levels to declining market demands. Unexpected decline in customer demands can result in excess or obsolete inventory and result in additional charges. Because certain of our sales, research and development and internal manufacturing overhead expenses are relatively fixed, a reduction in customer demand likely would decrease our gross margins and operating income.

We May Encounter Increased Competition

We may encounter substantial competition from other companies in the same market, including established companies with significant resources. Some of our competitors may have financial, technical, marketing or other capabilities that are more extensive than ours. They may be able to respond more quickly than we can to new or emerging technologies and other competitive pressures. We may not be able to compete successfully against our present or future competitors. Our failure to effectively compete could have a material adverse effect on our business, results of operations or financial condition.

There Are Limitations on the Protection of Our Intellectual Property and We May From Time to Time be Involved in Costly Intellectual Property Litigation or Indemnification

We rely on a combination of trade secret, patent, copyright and trademark laws combined with employee confidentiality, noncompetition and nondisclosure agreements to protect our intellectual property rights. There can be no assurance that the steps taken by us will be adequate to prevent misappropriation of our technology or intellectual property. Furthermore, there can be no assurance that third-parties will not assert infringement claims against us in the future.

Asserting our intellectual property rights or defending against third-party claims could involve substantial expense. In the event a third-party were successful in a claim that one of our processes infringed its proprietary rights, we could be required to pay substantial damages or royalties, or spend substantial amounts in order to obtain a license or modify processes so that they no longer infringe such proprietary rights. Any such events could have a material adverse effect on our business, results of operations or financial condition.

A Significant Portion of Our Business is Dependent on Cyclical Industries

Our business is dependent on the demand for products produced by end-users of industrial lasers, optical communication products and components for 3D sensing. Many of these end-users are in industries that have historically experienced a highly cyclical demand for their products. As a result, demand for our products is subject to these cyclical fluctuations. Fluctuations in demand could have a material adverse effect on our business, results of operations or financial condition.

20

Changes in Laws and Regulations Governing Data Privacy and Data Protection Could Have a Material Adverse Impact on our Business

We are subject to many data privacy, data protection, and data breach notification laws, including the European Union General Data Protection Regulation (“GDPR”), which became effective in May of 2018. While we have taken measures to assess the requirements of, and to comply with, the GDPR, as well as new and existing data-related laws and regulations of other jurisdictions, these measures may be challenged, including by authorities that regulate data-related compliance. We could incur significant expense in facilitating and responding to investigations, and if the measures we have taken prove to be inadequate, we could face fines, penalties or damages, and incur reputational harm, which could have a material adverse impact on our business.

Data Breach Incidents and Breakdown of Information and Communication Technologies Could Disrupt our Operations and Impact Our Financial Results

In the course of our business, we collect and store sensitive data, including intellectual property (both our own and that of our customers), as well as proprietary business information. We could be subject to service outages or breaches of security systems which may result in disruption, unauthorized access, misappropriation, or corruption of this information. Security breaches of our network or data, including physical or electronic break-ins, vendor service outages, computer viruses, attacks by hackers or similar breaches can create system disruptions, shutdowns, or unauthorized disclosure of confidential information. Although we have not experienced an incident, if we are unable to prevent such security or privacy breaches, our operations would be disrupted or we could suffer legal claims, loss of reputation, financial loss, property damage, or regulatory penalties because of lost or misappropriated information.

Global Economic Downturns May Adversely Affect Our Business, Operating Results and Financial Condition

Current and future conditions in the global economy have an inherent degree of uncertainty. As a result, it is difficult to estimate the level of growth or contraction for the global economy as a whole. It is even more difficult to estimate growth or contraction in various parts, sectors and regions of the economy, including industrial, military, optical communications, telecommunications, semiconductor, and medical and life science markets in which we participate. All aspects of our company forecast depend on estimates of growth or contraction in the markets we serve. Thus, prevailing global economic uncertainties render estimates of future income and expenditures very difficult to make.

Global economic downturns may affect industries in which our customers operate. These changes could include decreases in the rate of consumption or use of our customers’ products. Such conditions could have a material adverse effect on demand for our customers’ products, and in turn, on demand for our products.

Adverse changes may occur in the future as a result of declining or flat global or regional economic conditions, fluctuations in currency and commodity prices, wavering confidence, capital expenditure reductions, unemployment, decline in stock markets, contraction of credit availability or other factors affecting economic conditions. For example, factors that may affect our operating results include disruption in the credit and financial markets in the United States, Europe and elsewhere, adverse effects of slowdowns in the European and Chines economies, slowdown in the Chinese economy, reductions or limited growth in consumer spending or consumer credit, global trade tariffs and other adverse economic conditions that may be specific to the Internet, e-commerce and payments industries.

These changes may negatively affect sales of products and increase exposure to losses from bad debt and commodity prices, the cost and availability of financing, and costs associated with manufacturing and distributing products. Any economic downturn could have a material adverse effect on our business, results of operations or financial condition.

We Are Subject to Complex and Rapidly Changing Governmental Import and Export Regulations

We are subject to the passage of and changes in the interpretation of regulation by U.S. government entities at the federal, state and local levels and non-U.S. agencies, including, but not limited to, the following:

| • | We are required to comply with import laws and export control and economic sanctions laws, which may affect our transactions with certain customers, business partners and other persons, including dealings with or between our employees and subsidiaries. In certain circumstances, export control and economic sanctions regulations may prohibit the export of certain products, services and technologies. We may be required to obtain an export license before exporting a controlled item. Compliance with the import laws that apply to our businesses may restrict our access to, and may increase the cost of obtaining, certain products and could interrupt our supply of imported inventory.

| • | Exported technologies necessary to develop and manufacture certain products are subject to U.S. export control laws and similar laws of other jurisdictions. We may be subject to adverse regulatory consequences, including government oversight of facilities and export transactions, monetary penalties and other sanctions for violations of these laws. In certain instances, these regulations may prohibit the Company from developing or manufacturing certain of its products for specific end applications outside the United States.

21

Failure to comply with any of these laws and regulations could result in civil and criminal, monetary and non-monetary penalties, disruptions to our business, limitations on our ability to import and export products and services and damage to our reputation.

Changes in U.S. Trade Policies Could Impact the Company’s International Operations and the Cost of Imported Goods into the U.S., Which May Narrow the Size of Our Markets, Materially Impact Our Revenues or Increase Our Operating Costs and Expose Us to Contract Litigation

On March 23, 2018, President Trump announced new steel and aluminum tariffs, and on April 15, 2018, the U.S. Department of Commerce issued a denial order against two companies in the telecommunications market. Other international trade actions and initiatives also have been announced, notably the imposition by the U.S. of additional tariffs on products of Chinese origin, and China’s imposition of additional tariffs on U.S.-origin goods. If we cannot obtain relief from, or if we cannot take other action to mitigate the impact of, these additional duties, our business and profits may be materially and adversely affected. Further changes in U.S. trade policy, or additional sanctions, could result in retaliatory actions by other countries that could materially and negatively impact the volume of economic activity in the U.S., which, in turn, may decrease our access to customers and markets, reduce our revenues, and increase our operating costs.

We Have Entered into Supply Agreements which Commit Us to Supply Products on Specified Terms

We have supply agreements with some customers which require us to supply products and to allocate sufficient capacity to make these products. We have also agreed to pricing schedules and methodologies which could result in penalties if we fail to meet development, supply, capacity and quality commitments. Failure to do so may cause us to be unable to generate the amount of revenue or the level of profitability we expect from these arrangements. Our ability to realize a profit under some of these agreements will be subject to the level of customer demand, the cost of maintaining facilities and manufacturing capacity, and supply chain capability.

If we fail to fulfill our commitments under these supply agreements, our business, after using all remedies available, financial conditions and results of operations may suffer a material adverse effect.

We Depend on Highly Complex Manufacturing Processes That Require Feeder Materials, Components and Products from Limited Sources of Supply

Our operations are dependent upon a supply chain of difficult-to-make or difficult-to-refine products and materials. Some of our product inflow is subject to yield reductions from growth or fabrication losses, and thus the quantities we may receive are not consistently predictable. Customers may also change the specification for a product that our suppliers cannot meet.

We also make products for which the Company is one of the world’s largest suppliers. We use high-quality, optical grade ZnSe in the production of many of our IR optical products. We are a leading producer of ZnSe for our internal use and for external sale. The production of ZnSe is a complex process requiring a highly controlled environment. A number of factors, including defective or contaminated materials, could adversely affect our ability to achieve acceptable manufacturing yields of high quality ZnSe. Lack of adequate availability of high quality ZnSe could have a material adverse effect upon our business. There can be no assurance that we will not experience manufacturing yield inefficiencies which could have a material adverse effect on our business, results of operations or financial condition.

We produce hydrogen selenide gas which is used in our production of ZnSe. There are risks inherent in the production and handling of such material. Our lack of proper handling of hydrogen selenide could require us to curtail our production of hydrogen selenide. Our potential inability to internally produce hydrogen selenide could have a material adverse effect on our business, results of operations or financial condition.

In addition, we produce and use other high purity and relatively uncommon materials and compounds to manufacture our products including, but not limited to, ZnS, GaAs, Yttrium Aluminum Garnet, Yttrium Lithium Fluoride, Calcium Fluoride, Germanium, Selenium, Telluride, Bismuth Telluride and SiC. A significant failure of our internal production processes or our suppliers to deliver sufficient quantities of these necessary materials on a timely basis could have a material adverse effect on our business, results of operations or financial condition.

Our Global Operations Are Subject to Complex Legal and Regulatory Requirements

We manufacture products in the United States, China, Singapore, Vietnam, the Philippines, Germany, Switzerland, and the United Kingdom and through a contract manufacturer in Thailand. We also maintain direct sales offices in Hong Kong, Japan, Germany, China, Switzerland, Belgium, the United Kingdom, Italy, South Korea and Taiwan. Operations outside of the United States are subject to many legal and regulatory requirements, some of which are not aligned with others. These include tariffs, quotas, taxes and other market barriers, restrictions on the export or import of technology, potentially limited intellectual property protection, customs

22

import and export requirements, anti-corruption and anti-bribery laws, foreign exchange controls and cash repatriation restrictions, foreign investment rules and regulations, data privacy requirements, anti-competition laws, employment and labor laws, pensions and social insurance, and environmental health, and safety laws and regulations.

Compliance with these laws and regulations can be onerous and expensive, and requirements differ among jurisdictions. New laws, changes in existing laws and abrogation of local regulations by national laws result in significant uncertainties in how they will be interpreted and enforced. Failure to comply with any of these foreign laws and regulations could have a material adverse effect on our business, results of operations or financial condition.

We Use and Generate Potentially Hazardous Substances that Are Subject to Stringent Environmental Regulations

Hazardous substances used or generated in some of our research and manufacturing facilities are subject to stringent environmental regulation. We believe that our handling of such substances is in material compliance with applicable local, state and federal environmental, safety and health regulations at each operating location. We invest substantially in proper personal protective equipment, process controls including monitoring and specialized training to minimize risks to employees, surrounding communities and the environment that could result from the presence and handling of such hazardous substances. When exposure problems or potential exposure problems have been uncovered, corrective actions have been implemented and re-occurrence has been minimal or non-existent.

We have in place an emergency response plan with respect to our generation and use of the hazardous substances Hydrogen Selenide, Hydrogen Sulfide, Arsine and Phosphine. Special attention has been given to all procedures pertaining to this gaseous material to minimize the chances of its accidental release into the atmosphere.

With respect to the manufacturing, use, storage and disposal of the low-level radioactive material Thorium Fluoride, our facilities and procedures have been inspected and licensed by the Nuclear Regulatory Commission. Thorium-bearing by-products are collected and shipped as solid waste to a government-approved low-level radioactive waste disposal site in Clive, Utah.

The generation, use, collection, storage and disposal of all other hazardous by-products, such as suspended solids containing heavy metals or airborne particulates, are believed by us to be in material compliance with regulations. We believe that we have obtained all of the permits and licenses required for operation of our business.

We do not carry environmental impairment insurance. Although we do not know of any material environmental, safety or health problems in our properties or processes or products, there can be no assurance that problems will not develop in the future which could have a material adverse effect on our business, results of operations or financial condition.

We May Be Adversely Affected by Climate Change Regulations

In many of the countries in which we operate, government bodies are increasingly enacting legislation and regulations in response to potential impacts of climate change. These laws and regulations may be mandatory. They have the potential to impact our operations directly or indirectly as a result of required compliance by our customers or our supply chain. Inconsistency of regulations may also affect the costs of compliance with such laws and regulations. Assessments of the potential impact of future climate change legislation, regulation and international treaties and accords are uncertain, given the wide scope of potential regulatory change in countries in which we operate.

We may incur increased capital expenditures resulting from required compliance with revised or new legislation or regulations, added costs to purchase or lower profits from sales of our products, allowances or credits under a “cap and trade” system, increased insurance premiums and deductibles as new actuarial tables are developed to reshape coverage, a change in competitive position relative to industry peers, and changes to profit or loss arising from increased or decreased demand for goods produced by us and indirectly, from changes in costs of goods sold.

Some Systems That Use our Products Are Complex in Design, and Our Products May Contain Defects that Are Not Detected Until Deployed Which Could Increase Our Costs, Reduce Our Revenues, Cause Us to Lose Key Customers and May Expose Us to Litigation Arising From Derivative Lawsuits Related to Consumer Products

Some systems that use our products are inherently complex in design and require ongoing maintenance. Our customers may discover defects in our products after the products have been fully deployed and operated under peak stress conditions. In addition, some of our products are combined with products from other vendors which may contain defects. Should problems occur, it may be difficult to identify the source of the problem. If we are unable to correct defects or other problems, we could experience, among other things loss of customers, increased costs of product returns and warranty expenses, damage to our brand reputation, failure to attract new customers or achieve market acceptance, diversion of development and engineering resources, or legal action by our customers.

23

The occurrence of any one or more of the foregoing factors could have a material adverse effect on our business, res ults of operations or financial condition.

Unfavorable Changes in Tax Rates, Tax Liabilities or Tax Accounting Rules Could Negatively Affect Future Results

As a global company, we are subject to taxation in the United States and various other countries and jurisdictions. As such, we must exercise a level of judgment in determining our worldwide tax liabilities. Our future tax rates could be affected by changes in the composition of earnings in countries with differing tax rates or changes in tax laws. Changes in tax laws or tax rulings may have a significantly adverse impact on our effective tax rate. For example, proposals for fundamental U.S. international tax reform, if enacted, could have a significant adverse impact on our effective tax rate.

The enactment of the Tax Cuts and Jobs Act (the “Act”) in December 2017 significantly affected U.S. tax law by changing how the U.S. imposes tax on multinational corporations. The U.S. Department of Treasury has broad authority under the Act to issue regulations and interpretive guidance. We have applied available guidance to estimate our tax obligations, but new guidance issued by the U.S. Treasury Department may cause us to make adjustments to our tax estimates in future periods. The Securities and Exchange Commission has issued Staff Accounting Bulletin No. 118 (“SAB 118”) acknowledging that companies will potentially encounter situations for which the analysis of certain income tax effects of the Act will be incomplete by the time financial statements are required to be issued for reporting periods that include the enactment date. In these situations, SAB 118 provides that reasonable estimates may be made for certain effects of the Act. We have recorded provisional amounts using reasonable estimates based on the guidance in SAB 118 and we anticipate adjustments to such estimates as additional analysis is completed and new regulations and guidance are issued.

In addition, we are subject to regular examination of our income tax returns by the Internal Revenue Service and other tax authorities. We regularly assess the likelihood of favorable or unfavorable outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. Although we believe our tax estimates are reasonable, there can be no assurance that any final determination will not be materially different than the treatment reflected in our historical income tax provision and accruals, which could materially and adversely affect our business, results of operation or financial condition.

Increases in Commodity Prices May Adversely Affect Our Results of Operations and Financial Condition

We are exposed to a variety of market risks, including the effects of increases in commodity prices. Our businesses purchase, produce and sell high-purity selenium and other raw materials based upon quoted market prices from minor metal exchanges. The negative impact from increases in commodity prices may not be recovered through our product sales which could have a material adverse effect on our net earnings and financial condition.

Natural Disasters or Other Global or Regional Catastrophic Events Could Disrupt Our Operations, Give Rise to Substantial Environmental Hazards and Adversely Affect Our Results

We may be exposed to business interruptions due to catastrophe, natural disaster, pandemic, terrorism or acts of war that are beyond our control. Disruptions to our facilities or systems, or to those of our key suppliers, could also interrupt operational processes and adversely impact our ability to manufacture our products and provide services and support to our customers. As a result, our business, results of operations or financial condition could be materially adversely affected.

Our Success Depends on Our Ability to Attract, Retain and Develop Key Personnel and Requires Continued Good Relations With Our Employees

We are highly dependent upon the experience and continuing services of certain scientists, engineers, production and management personnel. Competition for the services of these personnel is intense. There can be no assurance that we will be able to retain or attract the personnel necessary for our success. The loss of the services of our key personnel could have a material adverse effect on our business, results of operations or financial condition.

Our Stock Price Has Been Volatile in the Past and May Be Volatile in the Future

The market price for our common stock on The Nasdaq Global Select Market varied between a high of $53.08 and a low of $34.00 in the fiscal year ended June 30, 2018. We expect that this volatility will continue. Factors that could cause fluctuation in our stock price include, among other things, general economic and market conditions, actual or anticipated variations in operating results, changes in financial estimates by securities analysts, our inability to meet or exceed securities analysts’ estimates or expectations, conditions or trends in the industries in which our products are purchased, announcements by us or our competitors of significant acquisitions, strategic partnerships, divestitures, joint ventures or other strategic initiatives, capital commitments, additions or departures of key personnel, sales of our common stock or equity-linked securities and issuance of shares of our common stock in connection with conversions of our outstanding convertible senior notes.

24

Many of these factors are beyond our control. However, these factors could cause the market price of our common stock to decline, regardless of our actual operating performance. In addi tion, in recent years, the stock market in general, and The Nasdaq Stock Market and the securities of technology companies in particular, have experienced extreme price and volume fluctuations. These fluctuations have often been unrelated or disproportiona te to the operating performance of individual companies. These broad market fluctuations have in the past, and may in the future, materially and adversely affect our stock price, regardless of our operating results. This volatility may affect the price at which our shareholders can sell our common stock.

Some Anti-takeover Provisions Contained in Our Articles of Incorporation and By-laws, as Well as Provisions of Pennsylvania Law, Could Impair a Takeover Attempt, Which Could Also Reduce the Market Price of Our Common Stock

Our articles of incorporation and by-laws contain provisions that could make us a less attractive target for a hostile takeover and could make more difficult or discourage a merger proposal, a tender offer or a proxy contest. Such provisions include:

| • | A requirement that shareholder-nominated director nominees be nominated in advance of the meeting at which directors are elected and that specific information be provided in connection with such nomination;

| • | The ability of our board of directors to issue additional shares of common stock or preferred stock without shareholder approval; and

| • | Certain provisions requiring supermajority approval (at least two-thirds of the votes cast by all shareholders entitled to vote thereon, voting together as a single class).

In addition, the Pennsylvania Business Corporation Law (the “BCL”) contains provisions that may have the effect of delaying or preventing a change in control of us or changes in our management. Many of these provisions are triggered if any person or group acquires, or discloses intent to acquire, 20% or more of a corporation’s voting power, subject to certain exceptions. These provisions:

| • | provide the other shareholders of the corporation with certain rights against the acquiring group or person;

| • | prohibit the corporation from engaging in a broad range of business combinations with the acquiring group or person;

| • | restrict the voting and other rights of the acquiring group or person; and

| • | provide that certain profits realized by the acquiring group or person from the sale of our equity securities belong to and are recoverable by us.

Regardless of the amount of a person’s holdings, if a shareholder or shareholder group (including affiliated persons) would be a party to certain proposed transactions with us or would be treated differently from other shareholders of ours in certain proposed transactions, the BCL requires approval by a majority of votes entitled to be cast by all shareholders other than the interested shareholder or affiliate group, unless the transaction is approved by independent directors or other criteria are satisfied. Furthermore, under the BCL, a “short-form” merger of II-VI cannot be implemented without the consent of our board of directors.

In addition, as permitted by Pennsylvania law, an amendment to our articles of incorporation or other corporate action that is approved by shareholders may provide mandatory special treatment for specified groups of non-consenting shareholders of the same class. For example, an amendment to our articles of incorporation or other corporate action may provide that shares of common stock held by designated shareholders of record must be cashed out at a price determined by the corporation, subject to applicable dissenters’ rights.

Furthermore, the BCL provides that directors may, in discharging their duties, consider, to the extent they deem appropriate, the effects of any action upon shareholders, employees, suppliers, customers and the communities in which its offices are located. Directors are not required to consider the interests of shareholders to a greater degree than other constituencies’ interests. The BCL expressly provides that directors do not violate their fiduciary duties solely by relying on “poison pills” or the anti-takeover provisions of the BCL. We do not currently have a “poison pill.”

All of these provisions may limit the price that investors may be willing to pay for shares of our common stock.

Because We Do Not Currently Intend to Pay Dividends, Holders of Our Common Stock Will Benefit from an Investment in Our Common Stock Only If It Appreciates in Value, and by the Intended Anti-Dilution Actions of Our Share-Buyback Program

We have never declared or paid any dividends on our common stock, and do not expect to pay cash dividends in the foreseeable future. We currently anticipate that we will retain any future earnings to support operations and to finance the development of our business. As a result, the success of an investment in our common stock will depend entirely upon future appreciation in its value. There is no guarantee that our common stock will maintain its value or appreciate in value.

On August 22, 2018, the last reported sale price for the Company’s common stock was $47.15 per share. As of such date, there were approximately 806 holders of record of our common stock. The Company historically has not paid cash dividends and does not presently anticipate paying cash dividends in the future.

ISSUER PURCHASES OF EQUITY SECURITIES

In August 2017, in conjunction with the Company’s offering and sale of our outstanding convertible notes, the Company’s Board of Directors authorized the Company to purchase up to $50 million of its common stock with a portion of the net proceeds received from the offering and sale of the Notes. The shares that were purchased by the Company pursuant to this authorization were retained as treasury stock and are available for general corporate purposes. The Company purchased 1,414,900 shares of its common stock for approximately $49.9 million pursuant to this authorization.

In August 2014, the Company’s Board of Directors authorized the Company to purchase up to $50 million of its common stock through a share repurchase program (the “Program”) that calls for shares to be purchased in the open market or in private transactions from time to time. The Program has no expiration and may be suspended or discontinued at any time. Shares purchased by the Company are retained as treasury stock and are available for general corporate purposes. As of June 30, 2018, the Company has cumulatively purchased 1,316,587 shares of its common stock pursuant to the Program for approximately $19.0 million. The dollar value of shares as of June 30, 2018 that may yet be purchased under the Program is approximately $31.0 million.

Item 7. | MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Forward-Looking Statements

Certain statements contained in this Management’s Discussion and Analysis of Financial Condition and Results of Operations are forward-looking statements. Forward-looking statements are also identified by words such as “expects,” “anticipates,” “believes,” “intends,” “plans,” “projects” or similar expressions. Actual results could differ materially from those anticipated in these forward-looking statements for many reasons, including those potential risks set forth in Item 1A, of this Annual Report on Form 10-K, which are incorporated herein by reference.

Overview

II-VI Incorporated (“II-VI,” the “Company,” “we,” “us” or “our”), a worldwide leader in engineered materials and optoelectronic components, is a vertically integrated manufacturing company that develops innovative products for diversified applications in the industrial materials processing, optical communications, military, consumer electronics, semiconductor equipment, life science and automotive applications . The Company produces a wide variety of application-specific photonic and electronic materials and components, and deploys them in various forms, including integration with advanced software.

The Company generates revenues, earnings and cash flows from developing, manufacturing and marketing engineered materials and optoelectronic components and devices for precision use in industrial materials processing, optical communications, consumer electronics, semiconductor equipment, life sciences and automotive applications. We also generate revenue, earnings and cash flows from government funded research and development contracts relating to the development and manufacture of new technologies, materials and products.

Our customer base includes OEMs, laser end-users, system integrators of high-power lasers, manufacturers of equipment and devices for the industrial, optical communications, military, semiconductor, medical and life science markets, consumer, U.S. government prime contractors, various U.S. Government agencies and thermoelectric integrators.

As we grow, we are focused on scaling our Company and deriving the benefits of vertical integration as we strive to be a best in class competitor in all of our highly competitive markets. The Company may elect to change the way in which the Company operates or is organized in the future to enable the most efficient implementation of its strategy.

Critical Accounting Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) and the Company’s discussion and analysis of its financial condition and results of operations requires the Company’s management to make judgments, assumptions and estimates that affect the amounts reported in its Consolidated Financial Statements and accompanying notes. Note 1 of the Notes to our Consolidated Financial Statements contained in Item 8 of this Annual Report on Form 10-K describes the significant accounting policies and accounting methods used in the preparation of the Company’s Consolidated Financial Statements. Management bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates.

Management believes the Company’s critical accounting estimates are those related to revenue recognition, inventory valuation, business combinations, impairment of goodwill and indefinite-lived intangible assets, accrual of income taxes and accounting for share-based compensation. Management believes these estimates to be critical because they are both important to the portrayal of the Company’s financial condition and results of operations, and they require management to make judgments and estimates about matters that are inherently uncertain.

Management has discussed the development and selection of these critical accounting estimates with the Audit Committee of the Board of Directors and the Audit Committee has reviewed the related disclosure. In addition, there are other items within our consolidated financial statements that require estimation, but are not deemed critical as described above. Changes in estimates used in these and other items could have a material impact on the consolidated financial statements.

Revenue Recognition

Revenues for product shipments are realizable when we have persuasive evidence of a sales arrangement, the product has been shipped or delivered, the sales price is fixed or determinable and collectability is reasonably assured. Title and risk of loss passes from the Company to its customer at the time of shipment in most cases, with the exception of certain customers for whom customer’s title does not pass and revenue is not recognized until the customer has received the product at its physical location.

31

The Company’s revenue recognition policy is consistently applied across the Company’s segmen ts, product lines and geographical locations. Further, for the periods covered herein, we did not have post shipment obligations such as training or installation, customer acceptance provisions, credits and discounts, rebates and price protection or other similar privileges. Our distributors and agents are not granted price protection. Our distributors and agents, who generate less than 10% of consolidated revenue, have no additional product return rights beyond the right to return defective products covere d by our warranty policy. We believe that our revenue recognition practices are consistent with Staff Accounting Bulletin 104 and that we have adequately considered the requirements of Accounting Standards Codification 605 Revenue Recognition. Revenues gen erated from transactions other than product shipments are contract-related and have historically accounted for approximately 1% of the Company’s consolidated revenues.

Inventory

The Company generally records an inventory adjustment as a charge against earnings for all products on hand for more than 12 to 24 months, depending on the products that have not been sold to customers or cannot be further manufactured for sale to alternative customers. An additional charge may be recorded for products on hand that are in excess of product sold to customers over the same periods noted above. If actual market conditions are less favorable than projected, additional inventory adjustments may be required. The Company’s inventory adjustments have historically been proven to be materially correct based upon actual write-offs incurred.

Business Acquisitions

The Company accounts for business acquisitions by establishing the acquisition-date fair value as the measurement for all assets acquired and liabilities assumed. Certain provisions of U.S. GAAP prescribe, among other things, the determination of acquisition-date fair value of consideration paid in a business combination (including contingent consideration) and the exclusion of transaction and acquisition-related restructuring costs from acquisition accounting.

Goodwill and Indefinite-Lived Intangibles

The Company tests goodwill and indefinite-lived intangible assets for impairment annually, and when events or changes in circumstances indicate that goodwill or indefinite-lived intangible assets might be impaired. Other intangible assets are amortized over their estimated useful lives. The determination of the estimated useful lives of other intangible assets and whether goodwill or indefinite-lived intangibles are impaired requires us to make judgments based on long-term projections of future performance. Estimates of fair value are based on our projection of revenues, operating costs and cash flows of each reporting unit, considering historical and anticipated results and general economic and market conditions and their projections. The fair values of the reporting units are determined using a discounted cash flow analysis based on historical and projected financial information as well as market analysis. The annual goodwill impairment analysis considers the financial projections of the reporting unit based on our most recently completed long-term strategic planning processes and also considers the current financial performance compared to our prior projections of the reporting unit. Changes in our internal structuring, financial performance, judgments and projections could result in an impairment of goodwill or indefinite-lived intangible assets. As of June 30, 2018, no reporting units are at risk for impairment, as the fair value of the reporting units substantially exceeds the carrying values.

The Company has the option to perform a qualitative assessment of goodwill prior to completing the quantitative assessment described above, to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill and other intangible assets. If the Company concludes that this is the case, it must perform the quantitative assessment. Otherwise, the Company will forego the quantitative assessment process and does not need to perform any further testing. The Company did not use the optional qualitative assessment during the years ended June 30, 2018 and 2017.

As a result of the purchase price allocations from our acquisitions, and due to our decentralized structure, our goodwill is included in multiple reporting units which are the same as the Company’s operating segments. Due to the cyclical nature of our business, and the other factors described in the section on Risk Factors set forth in Item 1A of this Annual Report on Form 10-K, the profitability of our individual reporting units may periodically be affected by downturns in customer demand, operational challenges and other factors. These factors may have a relatively more pronounced impact on the individual reporting units as compared to the Company as a whole, and might adversely affect the fair value of the individual reporting units. If material adverse conditions occur that impact one or more of our reporting units, our determination of future fair value might not support the carrying amount of one or more of our reporting units, and the related goodwill would need to be impaired. Based upon our annual quantitative goodwill and indefinite-lived intangible assets impairment tests, the Company did not record any impairments of goodwill or indefinite-lived intangible assets for the fiscal year ended June 30, 2018.

0.25% Convertible Senior Notes

Our 0.25% convertible senior notes are accounted for in accordance with ASC 470, Accounting for Convertible Debt Instruments That May be Settled in Cash upon Conversion (Including Partial Cash Settlement). ASC Subtopic 470-20 requires the issuer of convertible debt that may be settled in shares or cash upon conversion at the issuer’s option, such as these notes, to account for the liability (debt) and equity (conversion option) components separately. The value assigned to the debt component is the estimated fair value as of the issuance date of a similar debt instrument without the conversion option. The amount of the equity component is calculated by deducting the fair value of the liability component from the principal amount of the convertible debt instrument. The resulting debt discount is amortized as additional non-cash interest expense over the expected life of the notes utilizing the effective interest method. Although ASC 470 has no impact on our actual past or future cash flows, it requires us to record non-cash interest expense as the debt discount is amortized.

Income Taxes

The Company prepares and files tax returns based on its interpretation of tax laws and regulations and records estimates based on these judgments and interpretations. In the normal course of business, the Company’s tax returns are subject to examination by various taxing authorities, which may result in future tax, interest and penalty assessments by these authorities. Inherent uncertainties exist in estimates of many tax positions due to changes in tax law resulting from legislation, regulation and/or as concluded through the various jurisdictions’ tax court systems. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. The amount of unrecognized tax benefits is adjusted for changes in facts and circumstances. For example, adjustments could result from significant amendments to existing tax law and the issuance of regulations or interpretations by the taxing authorities, new information obtained during a tax examination, or resolution of an examination. The Company believes that its estimates for uncertain tax positions are appropriate and sufficient to pay assessments that may result from examinations of its tax returns. The Company recognizes both accrued interest and penalties related to unrecognized tax benefits in income tax expense.

Management evaluates the realizability of deferred tax assets for each jurisdiction in which it operates. If the Company experiences cumulative pretax income in a particular jurisdiction in a three-year period including the current and prior two years, management normally concludes that the income tax assets will more likely than not be realizable and no valuation allowance is recognized, unless known or planned operating developments, or changes in tax laws, would lead management to conclude otherwise. However, if the Company experiences cumulative pretax losses in a particular jurisdiction in a three year period, management then considers a series of factors in the determination of whether the deferred tax assets can be realized. The Company has recorded valuation allowances against certain of its deferred tax assets, primarily those that have been generated from net operating losses in certain foreign taxing jurisdictions and acquired U.S. carryforwards. In evaluating whether the Company would more likely than not recover these deferred tax assets, it has not assumed any future taxable income or tax planning strategies in the jurisdictions associated with these carry-forwards where history does not support such an assumption. Implementation of tax planning strategies to recover these deferred tax assets or future income generation in these jurisdictions could lead to the reversal of these valuation allowances and a reduction of income tax expense.

Share-Based Compensation

The Company recognizes share-based compensation expense over the requisite service period of the individual grantees, which generally equals the vesting period. The Company utilizes the Black-Scholes valuation model for estimating the fair value of share-based equity expense, using assumptions such as the risk-free interest rate, expected stock price volatility, expected stock option life and expected dividend yield. The risk-free interest rate is derived from the average U.S. Treasury Note rate during the period, which approximates the rate in effect at the time of grant related to the expected life of the options. Expected volatility is based on the historical volatility of the Company’s common stock over the period commensurate with the expected life of the options. The expected life calculation is based on the observed time to post-vesting exercise and/or forfeitures of options by our employees. The dividend yield is zero, based on the fact the Company has never paid cash dividends and has no current intention to pay cash dividends in the future.

Fiscal Year 2018 Compared to Fiscal Year 2017

The Company aligns its organizational structure into the following three reporting segments for the purpose of making operational decisions and assessing financial performance: (i) II-VI Laser Solutions, (ii) II-VI Photonics, and (iii) II-VI Performance Products. The Company is reporting financial information (revenue through operating income) for these reporting segments in this Annual Report on Form 10-K.

Executive Summary

Net earnings for fiscal year 2018 were $88.0 million ($1.35 per-share diluted), compared to $95.3 million ($1.48 per-share diluted) for the same period last fiscal year. The decrease in net earnings during current fiscal year from fiscal year 2017 was primarily driven by provisions under the Act and the Company’s related actions. Under the Act, the Company’s effective tax rate for fiscal year 2018 was 28.0% compared to 19.8% in fiscal year 2017; the Company recorded an additional $8.0 million of income tax expense, primarily relating to withholding taxes on future repatriation of foreign earnings. The Company also increased its investment in internal research and development relating to its new optoelectronic laser platform with the acquisition of Kaiam Laser Limited, and it ramped up its investment in other operations to address market shifts to new technologies driven by advanced engineered materials. Fiscal year 2017 was favorably impacted by other income relating to earn-out and technology transfer income the Company received as part of the sale of the RF business of ANADIGICS. The Company recognized $7.0 million or $0.09 per share diluted of other income related to these transactions in fiscal year 2017.

Consolidated

Revenues. Revenues for the year ended June 30, 2018 increased 19% to $1,158.8 million, compared to $972.0 million for the prior fiscal year. The increase in revenues during the current fiscal year was driven by strong demand from customers across all of the Company’s business segments. In particular, II-VI Laser Solution realized a 26% revenue growth from the prior year, driven by increased demand from industrial based customers for CO2, fiber and direct diode optics and components. This segment also recorded increased shipments of its VCSELs products addressing the growing consumer electronics, datacom and other developing end markets. II-VI Performance Products recorded a 24% revenue increase during the current fiscal year, driven by strengthening demand for SiC substrate products addressing RF electronics and high-power switching and power conversion systems for automotive, communication and military markets.

Gross margin. Gross margin for the year ended June 30, 2018 was $461.3 million, or 39.8%, of total revenues, compared to $388.3 million, or 39.9%, of total revenues for the same period last fiscal year. Gross margin as a percentage of revenues was consistent with the prior fiscal year due to a balance of operating efficiencies and investments to expand capacity. The Company’s II-VI Photonic’s gross margin was negatively impacted by both product mix and the effects of foreign currency.

Internal research and development. Company-funded internal research and development (“IR&D”) expenses for the fiscal year ended June 30, 2018 were $117.2 million, or 10.1% of revenues, compared to $96.8 million, or 10.0% of revenues, last fiscal year. The increase in IR&D expenses is primarily the result of the current year acquisition of Kaiam Laser Limited, acquired in August 2017, which contributed $14.6 million of expense. The Company continues to ramp its investment in new material-based technologies addressing growing market trends in consumer electronics, communications and automotive markets.

Selling, general and administrative. Selling, general and administrative (“SG&A”) expenses for the year ended June 30, 2018 were $208.8 million, or 18.0% of revenues, compared to $176.0 million, or 18.1% of revenues, last fiscal year. SG&A expenses includes $3.7 million and $2.5 million, respectively, for the combined acquisitions of II-VI Integrated Photonics Inc. (“IPI”), acquired in June 2017, and Kaiam Laser Limited, acquired in August 2017. Exclusive of these acquisitions, the increase in SG&A is primarily due to increased operating costs to support the Company’s growing revenue and infrastructure base, as well as its ongoing merger and acquisition strategy. The Company is working to identify and capitalize on synergies created from the Company’s recent acquisitions and is working to improve the SG&A leverage in the upcoming fiscal 2019 and beyond.

34

Interest and other, net. Interest and other, net for the year end ed June 30, 2018 was expense of $13.1 million compared to income of $3.3 million last fiscal year. Included in interest and other, net were interest expense on long-term borrowings, earnings from equity investments, interest income on excess cash reserves, unrealized gains and losses on the Company’s deferred compensation plan, and foreign currency gains and losses. Interest expense increased $11.5 million due to the higher levels of the Company’s outstanding debt. The majority of the interest expense incre ase was related to the Company’s $345.0 million convertible debt issued in August 2017. The Company recognized $10.8 million of interest and amortization of debt discounts and issuance costs. Other income last fiscal year included approximately $7.0 millio n of income from earn-out and technology transfer agreements from the Company’s sale of its ANADIGICS’ RF business.

Income taxes. The Company’s year-to-date effective income tax rate at June 30, 2018 was 28.0%, compared to an effective tax rate of 19.8% last fiscal year. The variation between the Company’s effective tax rate and the U.S. statutory rate was primarily due to the Company’s foreign operations, which are subject to income taxes at lower statutory rates. The increase in the current fiscal year’s effective tax rate is the result of approximately $8.0 million of increased income tax expense relating to repatriation on foreign source earnings.

Segment Reporting

Revenues and operating income for each of the Company’s reportable segments are discussed below. Operating income differs from income from operations in that operating income excludes certain operational expenses included in other expense (income) – net, as reported. Management believes operating income to be a useful measure for investors, as it reflects the results of segment performance over which management has direct control and is used by management in its evaluation of segment performance. See “Note 12. Segment and Geographic Reporting,” to the Consolidated Financial Statements included in this Annual Report on Form 10-K for further information on the Company’s reportable segments and for the reconciliation of operating income to net earnings, which is incorporated herein by reference.

Gross margin. Gross margin as a percentage of revenues for the year ended June 30, 2017 was $388.3 million or 39.9%, compared to $312.8 million or 37.8% for the fiscal year ended June 30, 2016. The improvement in gross margin was primarily driven by incremental margins realized on the Company’s higher revenue levels, which increased approximately $145.0 million from the prior year, as well as favorable product mix primarily in the II-VI Photonics segment.

Internal research and development. Company-funded internal research and development expenses for the year ended June 30, 2017 were $96.8 million, or 10.0% of revenues, compared to $60.4 million, or 7.3% of revenues, for the fiscal year ended June 30, 2016. The increase in internal research and development expense for fiscal year 2017 was the result of the Company’s continued investments in the development of the technology required to produce new optoelectronic devices in large volume for future applications, as well as new product introductions across the Company’s segments.

Selling, general and administrative. SG&A expenses for the fiscal year ended June 30, 2017 were $176.0 million, or 18.1% of revenues, compared to $160.6 million, or 19.4% of revenues, for the fiscal year ended June 30, 2016. The increase in SG&A in absolute dollars was the result of a higher revenue base requiring more SG&A support. The Company experienced favorable leverage as a result of capitalizing on synergies created from the Company’s acquisitions over the past several years.

Interest and other, net. Interest and other, net for the year ended June 30, 2017 was income of $3.3 million compared to expense of $1.9 million for the year ended June 30, 2016. Included in interest and other, net were interest expense on borrowings, interest income on excess cash reserves, foreign currency gains and losses and contingent earnout and technology transfer income from the sale of the ANADIGICS RF business that occurred in June 2016. In particular, for the fiscal year ended June 30, 2017, other income consisted primarily of foreign currency gains of $1.3 million, income from the residual agreements on the sale of the RF business noted above of $7.0 million, and interest income of $0.9 million on the Company’s excess cash reserves, offset by interest expense of $6.8 million on outstanding borrowings. The fiscal year ended June 30, 2016 expense of $1.9 million included $3.1 million of interest expense on the Company’s outstanding borrowings, offset by $1.2 million of interest income on the Company’s excess cash reserves. The increase in interest expense in fiscal year 2017 was the result of higher levels of outstanding borrowings.

Income taxes. The Company’s year-to-date effective income tax rate at June 30, 2017 was 19.8%, compared to an effective tax rate of 27.3% for the fiscal year ended June 30, 2016. The variation between the Company’s effective tax rate and the U.S. statutory rate of 35% was primarily due to the Company’s foreign operations, which are subject to income taxes at lower statutory rates. The lower year-to-date effective tax rate was primarily driven by the reversal of certain valuation allowances triggered by the acquisition of IPI, which generated deferred tax liabilities that offset the previously reserved deferred tax asset.

0.25% Convertible Senior Notes

On August 24, 2017, the Company entered into a purchase agreement with Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representative 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 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.

The Notes are governed by an Indenture between the Company, as issuer, and U.S. Bank, National Association, as trustee. The Notes are our senior unsecured obligations and rank senior in right of payment 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 the 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 up, 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, cash, 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

40

certain events. The if-converted value of the Notes amounted to $318.5 million as of June 30, 2018 (based on the Company’s closing stock price on the last trading day of the year ended June 30, 2018).

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:

| a) | During any fiscal quarter (and only during such fiscal quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

| b) | During the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; or

| c) | Upon the occurrence of specified corporate events.

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 June 30, 2018, the Notes are not convertible. The Notes will become convertible upon the satisfaction of at least one of the above conditions. 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 Shareholders' equity.

The Company was in compliance with all the covenants set forth under the indenture.

The following table sets forth total interest expense recognized related to the Notes for the fiscal year ended June 30, 2018 (representing an effective interest rate of 4.5%):

Year ended June 30, |  | 2018 |
0.25% contractual coupon |  | $ | 731 |
Amortization of debt discount and debt issuance costs including initial purchaser discount |  |  | 10,058 |
Interest expense |  | $ | 10,789 |

The unamortized discount amounted to $49.3 million as of June 30, 2018 and is being amortized over 4 years.

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 June 30, 2018, the Company was in compliance with all financial covenants under its Amended Credit Facility.

The Company had aggregate availability of $246.4 million and $73.5 million under its lines of credit as of June 30, 2018 and 2017, respectively. The amounts available under the Company’s lines of credit are reduced by outstanding letters of credit. As of June 30, 2018 and 2017, total outstanding letters of credit supported by the credit facilities were $0.4 million and $1.3 million, respectively.

Weighted Average Interest Rate

The weighted average interest rate of total borrowings was 1.3% and 2.2% for the years ended June 30, 2018 and 2017, respectively. The weighted average of total borrowings for the fiscal years ended June 30, 2018 and 2017 was $476.6 million and $272.1 million, respectively.

Share Repurchase Programs

In August 2017, in conjunction with the Company’s offering and sale of the Convertible Notes, the Company’s Board of Directors authorized the Company to purchase up to $50 million of its common stock with a portion of the net proceeds received from the offering and sale of the Notes. The shares that were purchased by the Company pursuant to this authorization were retained as treasury stock and are available for general corporate purposes. The Company purchased 1,414,900 shares of its common stock for approximately $49.9 million pursuant to this authorization.

In August 2014, the Company’s Board of Directors authorized the Company to purchase up to $50 million of its common Stock through a share repurchase program (the “Program”) that calls for shares to be purchased in the open market or in private transactions from time to time. The Program has no expiration and may be suspended or discontinued at any time. Shares purchased by the Company are retained as treasury stock and available for general corporate purposes. As of June 30, 2018, the Company has cumulatively purchased 1,316,587 shares of its common stock pursuant to the Program for approximately $19.0 million

Our cash position, borrowing capacity and debt obligations are as follows (in millions):

|  | June 30, |  |  | June 30, |
|  | 2018 |  |  | 2017 |
Cash and cash equivalents |  | $ | 247.0 |  |  | $ | 271.9 |
Available borrowing capacity |  |  | 246.4 |  |  |  | 73.5 |
Total debt obligations |  |  | 439.0 |  |  |  | 342.0 |

The Company believes cash flow from operations, existing cash reserves and available borrowing capacity from its credit facilities will be sufficient to fund its needs for working capital, capital expenditures, repayment of scheduled long-term borrowings and capital lease obligations, investments in internal research and development, share repurchases, internal and external growth objectives at least through fiscal year 2019. The Company expects to complete its acquisition of CoAdna, Inc., a publically traded company on the Taiwan Stock Exchange, on or about September 1, 2018. The purchase price will be approximately $85.0 million, net of any cash acquired and will be financed by a combination of cash on hand and borrowings on the Company’s Amended Credit Facility.

The Company’s cash and cash equivalent balances are generated and held in numerous locations throughout the world, including amounts held outside the United States. As of June 30, 2018, the Company held approximately $218 million of cash and cash equivalents outside of the United States. Cash balances held outside the United States could be repatriated to the United States. The recently enacted Act created significant changes to the taxation of undistributed foreign earnings and has changed our future intentions regarding repatriation of earnings. The Company is currently evaluating the full impact of the Act and may update future cash repatriation intentions.

Off-Balance Sheet Arrangements

The Company’s off-balance sheet arrangements include the operating lease obligations and the purchase obligations disclosed in the contractual obligations table below, as well as letters of credit as discussed in Note 7 to the Company’s Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K. The Company enters into these off-balance sheet arrangements to acquire goods and services used in its business.

(1) | Interest payments represent both variable and fixed rate interest obligations based on the interest rate in place at June 30, 2018, relating to the Amended Credit Facility, the Notes and interest relating to the Company’s capital lease obligation.

(2) | Includes an obligation for the use of two parcels of land related to II-VI Performance Metals. The lease obligations extend through years 2039 and 2061, respectively.

(3) | A purchase obligation is defined as an agreement to purchase goods or services that is enforceable and legally binding on the Company and that specifies all significant terms, including fixed or minimum quantities to be purchased; minimum or variable price provisions, and the approximate timing of the transaction. These amounts are primarily comprised of open purchase order commitments to vendors for the purchase of supplies and materials.

(4) | Includes cash earnout opportunities based on II-VI EpiWorks and IPI for the achievement of certain agreed-upon financial and operational targets.

(5) | Includes the Company’s intention to acquire CoAdna Inc., during the first quarter of fiscal year 2019, in a cash transaction valued at approximately $85.0 million, net of any cash acquired.

Pension obligations are not included in the table above. The Company expects defined benefit plan employer contributions to be $2.7 million in 2019. Estimated funding obligations are determined by asset performance, workforce and retiree demographics, tax and employment laws and other actuarial assumptions which may change the annual funding obligations. The funded status of our defined benefit plans is disclosed in Note 15 to the Company’s Consolidated Financial Statements.

The gross unrecognized income tax benefits at June 30, 2018, which are excluded from the above table, were $10.3 million. The Company is not able to reasonably estimate the amount by which the liability will increase or decrease over time; however, at this time, the Company does not expect a significant payment related to these obligations within the next fiscal year.

Item 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

MARKET RISKS

The Company is exposed to market risks arising from adverse changes in foreign currency exchange rates and interest rates. In the normal course of business, the Company uses certain techniques and derivative financial instruments as part of its overall risk management strategy, primarily focused on its exposure to the Japanese Yen, Chinese Renminbi and the Euro. The Company also has transactions denominated in Euros, British Pounds Sterling, Chinese Renminbi and Swiss Francs. No significant changes have occurred in the techniques and instruments used other than those described below.

Foreign Exchange Risks

In the normal course of business, the Company enters into foreign currency forward exchange contracts with its financial institutions. The purpose of these contracts is to hedge ordinary business risks regarding foreign currencies on product sales and other transactions denominated in currencies other than the U.S. dollar. Foreign currency exchange contracts are used to limit transactional exposure to changes in currency rates.

43

Japanese Yen

The Company enters into foreign currency forward contracts that permit it to sell specified amounts of Japanese Yen expected to be received from its export sales for pre-established U.S. dollar amounts at specified dates. The forward contracts are denominated in the same foreign currencies in which export sales are denominated. These contracts provide the Company with an economic hedge in which settlement will occur in future periods, thereby limiting the Company’s exposure. These contracts had a total notional amount of $12.0 million and $12.7 million at June 30, 2018 and 2017, respectively.

A 10% change in the yen to U.S. dollar exchange rate would have changed revenues in the range from a decrease of approximately $8.1 million to an increase of approximately $9.9 million for the year ended June 30, 2018.

During June 2018, the Company entered into a $7.0 million month-to-month forward contract that matured on June 29, 2018, to limit exposure to the Yen. Upon expiration of this contract, the Company recorded a loss of $0.2 million in the Consolidated Statement of Earnings.

Chinese Renminbi

During June 2018, the Company entered into a $43.5 million month-to-month forward contract that matured on June 29, 2018, to limit exposure to the Chinese Renminbi. Upon expiration of this contract, the Company recorded a loss of $1.2 million in the Consolidated Statement of Earnings.

Euro

The Company has short-term intercompany notes that are denominated in U.S. dollars with certain European subsidiaries. A 10% change in the Euro to dollar exchange rate would have changed net earnings in the range from a decrease of $0.5 million to an increase of $0.6 million for the year ended June 30, 2018.

The Company monitors its positions and the credit ratings of the parties to these contracts. While the Company may be exposed to potential losses due to risk in the event of non-performance by the counterparties to these financial instruments, it does not currently anticipate such losses.

Assets and liabilities of foreign operations are translated into U.S. dollars using the period-end exchange rates, while income and expenses are translated using the average exchange rates for the reporting period. Translation adjustments are recorded as accumulated other comprehensive income within shareholders’ equity.

Interest Rate Risks

As of June 30, 2018, the Company’s total borrowings of $496.5 million consisted of $147.7 million variable rate debt borrowings from a line of credit of $80.0 million denominated in U.S. dollars, a term loan denominated in U.S. dollars of $65.0 million, a line of credit borrowing of $2.7 million denominated in Japanese yen. As such, the Company is exposed to changes in interest rates. A change in the interest rate of 100 basis points on these variable rate borrowings would have resulted in additional interest expense of $1.5 million for the fiscal year ended June 30, 2018.

Discount Rate Risks

As of June 30, 2018, a 10% change in the Company’s discount rate used to determine the pension benefit obligation of the Switzerland Defined Benefit Plan would have had an immaterial impact on the Consolidated Financial Statements.

Item 8. | FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management’s Responsibility for Preparation of the Financial Statements

Management is responsible for the preparation of the consolidated financial statements included in this Annual Report on Form 10-K. The consolidated financial statements were prepared in accordance with the accounting principles generally accepted in the United States of America and include amounts that are based on the best estimates and judgments of management. The other financial information contained in this Annual Report on Form 10-K is consistent with the consolidated financial statements.

Management’s Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s internal control system is designed to provide reasonable assurance concerning the reliability of the financial data used in the preparation of the Company’s consolidated financial statements, as well as reasonable assurance with respect to safeguarding the Company’s assets from unauthorized use or disposition.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement presentation and other results of such systems.

Management conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting as of June 30, 2018. In making this evaluation, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control – Integrated Framework (2013). Management’s evaluation included reviewing the documentation of its controls, evaluating the design effectiveness of controls and testing their operating effectiveness. Management excluded from the scope of its assessment of internal control over financial reporting the operations and related assets of Kaiam Laser Limited, Inc., which was acquired in August 2017. The recent acquisition excluded from management’s assessment of internal controls over financial reporting represented approximately $107.2 million and $98.1million of total assets and net assets, respectively, as of June 30, 2018 and approximately $3.4 million and $12.5 million of total revenues and net loss, respectively, for the fiscal year then ended. Based on the evaluation, management concluded that as of June 30, 2018, the Company’s internal controls over financial reporting were effective.

Ernst & Young LLP, an independent registered public accounting firm, has issued its report on the effectiveness of our internal control over financial reporting as of June 30, 2018. Its report is included herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of II-VI Incorporated and Subsidiaries

Opinion on Internal Control over Financial Reporting

We have audited II-VI Incorporated and Subsidiaries’ internal control over financial reporting as of June 30, 2018, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, II-VI Incorporated and Subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of June 30, 2018, based on the COSO criteria.

As indicated in the accompanying Management’s Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Kaiam Laser Limited, Inc., which is included in the June 30, 2018 consolidated financial statements of the Company and constituted $107.2 million and $98.1 million of total and net assets, respectively, as of June 30, 2018 and $3.4 million and $12.5 million of revenues and net loss, respectively, for the fiscal year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of Kaiam Laser Limited, Inc.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of June 30, 2018 and 2017, the related consolidated statements of earnings, comprehensive income, shareholders’ equity and cash flows for each of the three years in the period ended June 30, 2018, and the related notes and the financial statement schedule listed in the Index at Item 15(a)(2) and our report dated August 28, 2018 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

II-VI Incorporated and Subsidiaries

Notes to the Consolidated Financial Statements

Note 1. | Nature of Business and Summary of Significant Accounting Policies

Nature of Business. II-VI Incorporated and its subsidiaries (the “Company,” “we,” “us,” or “our”), a global leader in engineered materials and optoelectronic components and devices, is a vertically-integrated manufacturing company that develops, manufactures and markets engineered materials and optoelectronic components and devices for precision use in industrial materials processing, optical communications, military, consumer electronics, semiconductor equipment, life sciences and automotive applications. The Company markets its products through its direct sales force and through distributors and agents.

The Company uses certain uncommon materials and compounds to manufacture its products. Some of these materials are available from only one proven outside source. The continued high quality of these materials is critical to the stability of the Company’s manufacturing yields. The Company has not experienced significant production delays due to a shortage of materials. However, the Company does occasionally experience problems associated with vendor-supplied materials not meeting specifications for quality or purity. A significant failure of the Company’s suppliers to deliver sufficient quantities of necessary high-quality materials on a timely basis could have a material adverse effect on the Company’s results of operations.

Principles of Consolidation. The Consolidated Financial Statements include the accounts of the Company. All intercompany transactions and balances have been eliminated.

Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Foreign Currency Translation. For II-VI Singapore Pte., Ltd. and its subsidiaries, II-VI Laser Enterprise of the II-VI Laser Solutions segment, II-VI Network Solutions Division of the II-VI Photonics segment, and II-VI Performance Metals of the II-VI Performance Products segment, the functional currency is the United States (U.S.) dollar. The determination of the functional currency is made based on the appropriate economic and management indicators.

For all other foreign subsidiaries, the functional currency is the local currency. Assets and liabilities of those operations are translated into U.S. dollars using period-end exchange rates while income and expenses are translated using the average exchange rates for the reporting period. Translation adjustments are recorded as accumulated other comprehensive income within shareholders’ equity in the accompanying Consolidated Balance Sheets.

Cash and Cash Equivalents. The Company considers highly liquid investment instruments with an original maturity of three months or less to be cash equivalents. We place our cash and cash equivalents with high credit quality financial institutions and to date have not experienced credit losses in these instruments. Cash of foreign subsidiaries is on deposit at banks in China, Vietnam, Singapore, Japan, Switzerland, the Netherlands, Germany, the Philippines, Belgium, Italy, Hong Kong, the United Kingdom, South Korea and Taiwan.

Accounts Receivable. The Company establishes an allowance for doubtful accounts based on historical experience and believes the collection of revenues, net of this allowance, is reasonably assured.

Inventories. Inventories are valued at the lower of cost or net realizable value, with cost determined on the first-in, first-out basis. Inventory costs include material, labor and manufacturing overhead. In evaluating the net realizable value of inventory, management also considers, if applicable, other factors, including known trends, market conditions, currency exchange rates and other such issues. The Company generally records an inventory adjustment as a charge against earnings for all products on hand more than 12 to 24 months, depending on the products that have not been sold to customers or cannot be further manufactured for sale to alternative customers. An additional charge may be recorded for product on hand that is in excess of product sold to customers over the same periods noted above. The cumulative adjustments to the carrying value of inventory totaled $22.5 million and $18.5 million at June 30, 2018 and 2017, respectively.

Property, Plant and Equipment. Property, plant and equipment are carried at cost or fair value upon acquisition. Major improvements are capitalized, while maintenance and repairs are generally expensed as incurred. The Company reviews its property, plant and equipment and other long-lived assets for impairment whenever events or circumstances indicate that the carrying amounts may not be recoverable. Depreciation for financial reporting purposes is computed primarily by the straight-line method over the estimated useful lives for building, building improvements and land improvements of 10 to 20 years and three to 20 years for machinery and equipment.

53

Business Combinations. The Company accounts for business acquisitions by establishing the acquisition-date fair value as the measurement for all assets acquired and liabilities assumed. Certain provisions of U.S. GAAP prescribe, among other things, the determination of acquisition-date fair value of consideratio n paid in a business combination (including contingent consideration) and the exclusion of transaction and acquisition-related restructuring costs from acquisition accounting. The Company accounts for contingent consideration received in accordance with th e “Loss Recovery Approach” under U.S. GAAP. Contingent consideration is accounted for as a gain contingency and not recognized in other expense (income), net until all contingencies have been satisfied.

Goodwill. The excess purchase price over the fair value allocated to identifiable tangible and intangible net assets of businesses acquired is reported as goodwill in the accompanying Consolidated Balance Sheets. The Company tests goodwill for impairment at least annually as of April 1, or when events or changes in circumstances indicate that goodwill might be impaired. The evaluation of impairment involves comparing the current fair value of the Company’s reporting units to the recorded value (including goodwill). The Company uses a discounted cash flow (“DCF”) model and/or a market analysis to determine the current fair value of its reporting units. A number of significant assumptions and estimates are involved in estimating the forecasted cash flows used in the DCF model, including markets and market shares, sales volume and pricing, costs to produce, working capital changes and income tax rates. Management considers historical experience and all available information at the time the fair values of the reporting units are estimated. Goodwill impairment is now measured as 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 the option to perform a qualitative assessment of goodwill prior to completing the quantitative assessment described above to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill and other intangible assets. If the Company concludes that this is the case, it must perform the quantitative assessment. Otherwise, the Company will forego the quantitative assessment and does not need to perform any further testing. As of April 1 of fiscal years 2018 and 2017, the Company completed its annual impairment tests of its reporting units using the quantitative assessment. Based on the results of these analyses the Company’s goodwill was not impaired.

Intangibles. Intangible assets are initially recorded at their cost or fair value upon acquisition. Finite-lived intangible assets are amortized for financial reporting purposes using the straight-line method over the estimated useful lives of the assets ranging from five to 20 years. Indefinite-lived intangible assets are not amortized but tested annually for impairment at April 1, or when events or changes in circumstances indicate that indefinite-lived intangible assets might be impaired.

Investments in Other Entities. In the normal course of business, the Company enters into various types of investment arrangements, each having unique terms and conditions. These investments may include equity interests held by the Company in business entities, including general or limited partnerships, contractual ventures, or other forms of equity participation. The Company determines whether such investments involve a variable interest entity (“VIE”) based on the characteristics of the subject entity. If the entity is determined to be a VIE, then management determines if the Company is the primary beneficiary of the entity and whether or not consolidation of the VIE is required. The primary beneficiary consolidating the VIE must normally have both (i) the power to direct the activities of a VIE that most significantly affect the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE, in either case that could potentially be significant to the VIE. When the Company is deemed to be the primary beneficiary, the VIE is consolidated and the other party’s equity interest in the VIE is accounted for as a noncontrolling interest.

The Company generally accounts for investments it makes in VIEs in which it has determined that it does not have a controlling financial interest but has significant influence over and holds at least a 20% ownership interest using the equity method. Any such investment not meeting the parameters to be accounted under the equity method would be accounted for using the cost method unless the investment had a readily determinable fair value, at which it would then be reported.

If an entity fails to meet the characteristics of a VIE, management then evaluates such entity under the voting model. Under the voting model, management consolidates the entity if they determine that the Company, directly or indirectly, has greater than 50% of the voting shares and determines that other equity holders do not have substantive participating rights.

Commitments and Contingencies. Liabilities for loss contingencies arising from claims, assessments, litigation, fines, and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred. Such accruals are adjusted as further information develops or circumstances change. The Company had no material loss contingency liabilities at June 30, 2018 related to commitments and contingencies.

54

Income Taxes. Deferred income tax assets and liabilities are determined based on the differences between the consolidated financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred income tax assets to the amount more likely than not to be realized.

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution. The amount of unrecognized tax benefits is adjusted for changes in facts and circumstances. For example, adjustments could result from significant amendments to existing tax law and the issuance of regulations or interpretations by the taxing authorities, new information obtained during a tax examination, or resolution of an examination. The Company believes that its estimates for uncertain tax positions are appropriate and sufficient to pay assessments that may result from examinations of its tax returns. The Company recognizes both accrued interest and penalties related to unrecognized tax benefits in income tax expense.

Revenue Recognition. The Company recognizes revenues for product shipments when persuasive evidence of a sales arrangement exists, the product has been shipped or delivered, the sale price is fixed or determinable and collectability is reasonably assured. Title and risk of loss passes from the Company to its customer at the time of shipment in most cases with the exception of certain customers. For these customers, title does not pass and revenue is not recognized until the customer has received the product at its physical location.

The Company’s revenue recognition policy is consistently applied across the Company’s segments, product lines and geographical locations. Further for the periods covered herein, we did not have post shipment obligations such as training or installation, customer acceptance provisions, credits and discounts, rebates and price protection, or other similar privileges. Our distributors and agents are not granted price protection. Our distributors and agents, which comprise less than 10% of consolidated revenues, have no additional product return rights beyond the right to return defective products covered by our warranty policy. Revenues generated from transactions other than product shipments are contract related and have historically accounted for approximately 1% of consolidated revenues. We believe our revenue recognition practices have adequately considered the requirements under U.S. GAAP.

Shipping and Handling Costs. Shipping and handling costs billed to customers are included in revenues. Shipping and handling costs incurred by the Company are included in selling, general and administrative expenses in the accompanying Consolidated Statements of Earnings. Total shipping and handling revenue and costs included in revenues and in selling, general and administrative expenses were not significant for the fiscal years ended June 30, 2018, 2017 and 2016.

Research and Development. Internal research and development costs and costs not related to customer and government funded research and development contracts are expensed as incurred.

Share-Based Compensation. Share-based compensation arrangements require the recognition of the grant-date fair value of stock compensation in net earnings. The Company recognizes the share-based compensation expense over the requisite service period of the individual grantees, which generally equals the vesting period.

Accumulated Other Comprehensive Income. Accumulated other comprehensive income is a measure of all changes in shareholders’ equity that result from transactions and other economic events in the period other than transactions with owners. Accumulated other comprehensive (loss) income is a component of shareholders’ equity and consists of accumulated foreign currency translations adjustments and pension adjustments.

Fair Value Measurements. The Company applies fair value accounting for all financial assets and liabilities that are required to be recognized or disclosed at fair value in the financial statements. Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, the Company considers the principal or most advantageous market in which the Company would transact, and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions and credit risk.

Operating Leases. The Company classifies operating leases in accordance with the provisions of lease accounting. Rent expense under noncancelable operating leases with scheduled rent increases or rent holidays is accounted for on a straight-line basis over the lease term, beginning on the date of initial possession or the effective date of the lease agreement. The amount of the excess straight-line rent expense over scheduled payments is recorded as a deferred liability. The current portion of unamortized deferred lease costs is included in other accrued liabilities and the long-term portion is included in other liabilities in the Consolidated Balance Sheets.

55

Capital Leases. The Company accounts for capital leases at the lesser of the estimated fair market value of the leased property or the net present valu e of the aggregate future minimum lease payments. The current and long-term portion of the capital lease obligation is recorded in Other accrued liabilities and other liabilities, respectively, in the Consolidated Balance Sheet. Capital lease assets are in cluded in property, plant & equipment and are generally depreciated over the term of the lease. Interest expense on capital leases are included in interest expense in the Consolidated Statements of Earnings.

Recently Issued Financial Accounting Standards

Adopted Pronouncements

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 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 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

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09: Revenue from Contracts with Customers (Topic 606), that outlines a five-step revenue recognition model based on the principle 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 and services. This new standard became effective for the Company on July 1, 2018, and will be adopted using the modified retrospective transition method.

Based on review and analysis of our contracts, the standard primarily impacts our II-VI Performance Product segment, which has long-term production contracts with customers that sell to the U.S. Government. Prior to adoption of the new standard, revenue was generally recognized for these contracts at a point-in-time as units were shipped, while under the new standard, revenue will be recognized over time, principally under the units-of-delivery method which faithfully depicts the transfer of control to the customers. This change will result in an immaterial change in revenue for these contracts and no transition adjustment is anticipated for July 1, 2018.

We have updated the accounting policies affected by this standard, redesigned our related internal controls over financial reporting and are expanding the disclosures to be included in our first quarter 2019 Condensed Consolidated Financial Statements to meet the new requirements.

Other Pronouncements Currently Under Evaluation

In June 2018, the FASB issued ASU 2018-07, “Improvements to Nonemployee Share-Based Payment Accounting”, which simplifies the accounting for share-based payments granted to nonemployees for goods and services. Under the ASU, most of the guidance on such payments to nonemployees would be aligned with the requirements for share-based payments granted to employees. The standard will be effective for the Company’s 2020 fiscal year. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company is evaluating the impact of this guidance 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 adoption of the ASU is not expected to have a material effect 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.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842).

Note 3. | Other Investments

Purchase of Equity Investment

In November 2017, the Company acquired a 93.8% equity investment in a privately-held company for $51.5 million. In addition, the Company paid $0.2 million for a working capital adjustment to that purchase price. The Company’s pro-rata share of earnings from this investment since the acquisition date was $2.4 million for the year ended June 30, 2018 and was recorded in other expense (income), net in the Consolidated Statement of Earnings.

This investment is accounted for under the equity method of accounting (“Equity Investment”). The following table summarizes the Company's equity in this nonconsolidated investment:

|  | Interest |  | Ownership % as of |  |  | Equity as of |
Location |  | Type |  | June 30, 2018 |  |  | June 30, 2018 ($000) |
USA |  | Equity Investment |  | 93.8% |  |  | $ | 56,331 |

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 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 June 30, 2018, the Company’s maximum financial statement exposure related to the Equity Investment was approximately $56.3 million, which is included in Investments on the Consolidated Balance Sheet as of June 30, 2018.

59

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 their outstanding interests 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 equity 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 Consolidated Balance Sheet in accordance with ASC 815-10, Derivatives and Hedging. The fair value of the net put option is adjusted as necessary on a quarte rly basis, with any changes in the fair value recorded through earnings. The change in fair value of the net purchase option from the investment date to June 30, 2018 was not material.

Guangdong Fuxin Electronic Technology Equity Investment

The Company has an equity investment of 20.2% in Guangdong Fuxin Electronic Technology, based in Guangdong Province, China, which is accounted for under the equity method of accounting. The total carrying value of the investment recorded at June 30, 2018 and June 30, 2017 was $12.9 million and $11.7 million, respectively. During the years ended June 30, 2018, 2017 and 2016, the Company’s pro-rata share of earnings from this investment was $1.2 million, $0.7 million and $0.1 million, respectively, and was recorded in other expense (income), net in the Consolidated Statements of Earnings. During the years ended June 30, 2018, 2017 and 2016, the Company received dividends from this equity investment of $0.4 million, $0.4 million and $0.6 million, respectively.

0.25% Convertible Senior Notes

On August 24, 2017, the Company entered into a purchase agreement with Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representative 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.

The Notes are governed by an Indenture between the Company, as issuer, and U.S. Bank, National Association, as trustee. The Notes are our senior unsecured obligations and rank senior in right of payment 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 the 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 up, 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, cash, 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. The if-converted value of the Notes amounted to $318.5 million as of June 30, 2018 (based on the Company’s closing stock price on the last trading day of the year ended June 30, 2018).

62

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 c onversion 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:

| a) | During any fiscal quarter (and only during such fiscal quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

| b) | During the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; or

| c) | Upon the occurrence of specified corporate events.

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 June 30, 2018, the Notes are not yet convertible. The Notes will become convertible upon the satisfaction of at least one of the above conditions. 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 Shareholders' Equity.

The Company was in compliance with all the covenants set forth under the indenture.

The following table sets forth total interest expense recognized related to the Notes for the fiscal year ended June 30, 2018 (representing an effective interest rate of 4.5%):

Year ended June 30, |  | 2018 |
0.25% contractual coupon |  | $ | 731 |
Amortization of debt discount and debt issuance costs including initial purchaser discount |  |  | 10,058 |
Interest expense |  | $ | 10,789 |

The unamortized discount amounted to $49.3 million as of June 30, 2018 and is being amortized over 4 years.

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 June 30, 2018, 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 ($4.5 million) facility. The Yen line of credit matures in August 2020. The interest rate equal to LIBOR, as defined in the loan agreement, plus 0.625% to 1.75%. At June 30, 2018 and 2017, the Company had 300 million yen outstanding under the line of credit. Additionally, the facility is subject to certain covenants, including

those relating to minimum interest coverage and maximum leverage ratios. As of June 30, 2018, the Company had $2.7 million outstanding and was in compliance with all 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 January 2020.

Singapore Line of Credit

The Company has a line of credit facility with a Singapore bank which permits maximum borrowings in the local currency of approximately $0.6 million for the fiscal years ended June 30, 2018 and 2017, respectively. Borrowings are payable upon demand with interest charged at the rate of 1.00% above the bank’s prevailing prime lending rate. The interest rate was 5.25% at June 30, 2018 and June 30, 2017. At June 30, 2018 and 2017, there were no outstanding borrowings under this facility. The Company had $0.3 million and $0.2 million of letters of credit supported by the Singapore line of credit facility as of June 30, 2018 and 2017, respectively.

Aggregate Availability

The Company had aggregate availability of $246.4 million and $73.5 million under its lines of credit as of June 30, 2018 and 2017, respectively. The amounts available under the Company’s lines of credit are reduced by outstanding letters of credit. As of June 30, 2018 and 2017, total outstanding letters of credit supported by the credit facilities were $0.4 million and $1.3 million, respectively.

Weighted Average Interest Rate

The weighted average interest rate of total borrowings was 1.3% and 2.2% for the years ended June 30, 2018 and 2017, respectively. The weighted average of total borrowings for the fiscal years ended June 30, 2018 and 2017 was $476.6 million and $272.1 million, respectively.There are no interim maturities or minimum payment requirements related to the credit facilities before their respective expiration dates.

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 was 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 June 30, 2018, 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 and therefore may change.

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 to income tax expense of $8.0 million for the year ended June 30, 2018.

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 year ended June 30, 2018, 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 and 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.

During the fiscal years ended June 30, 2018, 2017, and 2016, net cash paid by the Company for income taxes was $21.3 million, $23.6 million, and $18.5 million, respectively.

Our foreign subsidiaries in the Philippines operate under various tax holiday arrangements. The benefits of such arrangements phase out through the fiscal year ended June 30, 2019. The impact of the tax holidays on our effective rate is a reduction in the rate of 0.17%, 0.31% and 0.37% for the fiscal years ended June 30, 2018, 2017 and 2016, respectively, and the impact of the tax holidays on diluted earnings per share is immaterial.

The Company has the following gross operating loss carryforwards and tax credit carryforwards as of June 30, 2018:

Type |  | Amount |  |  | Expiration Date
($000) |  |  |  |  |  |
Tax credit carryforwards: |  |  |  |  |  |
Federal research and development credits |  | $ | 13,913 |  |  | June 2019-June 2038
Foreign tax credits |  |  | 251 |  |  | June 2024-June 2028
State tax credits |  |  | 5,594 |  |  | June 2019-June 2038
Operating loss carryforwards: |  |  |  |  |  |
Loss carryforwards - federal |  | $ | 68,661 |  |  | June 2020-June 2038
Loss carryforwards - state |  |  | 47,756 |  |  | June 2019-June 2038
Loss carryforwards - foreign |  |  | 16,347 |  |  | June 2019-June 2028

The Company has recorded a valuation allowance against the majority of the loss and credit carryforwards. The Company’s U.S. federal loss carryforwards, federal research and development credit carryforwards, and certain state tax credits resulting from the Company’s acquisitions are subject to various annual limitations under Section 382 of the U.S. Internal Revenue Code.

Change s in the liability for unrecognized tax benefits for the fiscal years ended June 30, 2018, 2017 and 2016 were as follows:

Increases in current year tax positions |  |  | 2,536 |  |  |  | 895 |  |  |  | 2,146 |
Increases in prior year tax positions |  |  | 224 |  |  |  | 2,605 |  |  | 190 |

Expiration of statute of limitations |  |  | (436 | ) |  |  | (339 | ) |  |  | (732 | )
Ending balance |  | $ | 9,892 |  |  | $ | 7,577 |  |  | $ | 5,559 |

The Company classifies all estimated and actual interest and penalties as income tax expense. During fiscal year 2018 and 2017, there was $0.3 million and $0.5 million of interest and penalties within income tax expense, respectively. During the fiscal year 2016, there was no interest or penalties within income tax expense. The Company had $0.6 million and $0.3 million of interest and penalties accrued at June 30, 2018 and 2017, respectively. The Company has classified the uncertain tax positions as non-current income tax liabilities, as the amounts are not expected to be paid within one year. Including tax positions for which the Company determined that the tax position would not meet the more likely than not recognition threshold upon examination by the tax authorities based upon the technical merits of the position, the total estimated unrecognized tax benefit that, if recognized, would affect our effective tax rate, was approximately $1.6 million and $1.3 million at June 30, 2018 and 2017, respectively. The Company expects a decrease of $3.4 million of unrecognized tax benefits during the next 12 months due to the expiration of statutes of limitation.

Fiscal years 2015 to 2018 remain open to examination by the Internal Revenue Service, fiscal years 2013 to 2018 remain open to examination by certain state jurisdictions, and fiscal years 2008 to 2018 remain open to examination by certain foreign taxing jurisdictions. The Company is currently under examination for the U.S. Federal income tax return for the year ended June 30, 2016; certain subsidiary companies in the Philippines for the year ended June 30, 2017; and Germany for the years ended June 2012 through June 2015. The Company believes its income tax reserves for these tax matters are adequate.

Note 9. | Earnings Per Share

The following table sets forth the computation of earnings per share for the periods indicated. Basic net income per share has been computed using the weighted average number of shares of common stock outstanding during the period. Diluted net income per share has been computed using the weighted average number of common shares outstanding during the period plus dilutive potential shares of common stock from (1) stock options, performance and restricted shares (under the treasury stock method) and (2) convertible debt (under the If-Converted method) outstanding during the period. The Company’s convertible debt calculated under the If-Converted method was antidilutive for the fiscal year 2018 and was excluded from the calculation of earnings per share.

Rent expense was approximately $17.0 million, $14.7 million, and $14.2 million for the fiscal years ended June 30, 2018, 2017 and 2016, respectively.

Note 11. | Share-Based Compensation Plans

The Company’s Board of Directors adopted the II-VI Incorporated Amended and Restated 2012 Omnibus Incentive Plan (the “Plan”) which was approved by the shareholders at the Annual Meeting in November 2014 as amended. The Plan provides for the grant of non-qualified stock options, stock appreciation rights, restricted shares, restricted share units, deferred shares, performance shares 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 Plan has vesting provisions predicated upon the death, retirement or disability of the grantee. As of June 30, 2018, there were approximately 955,000 shares available to be issued under the Plan, including forfeited shares from predecessor plans.

The Company records share-based compensation expense for these awards which requires the recognition of the grant-date fair value of share-based compensation in net earnings. The Company recognizes the share-based compensation expense 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 for the fiscal years ended June 30, 2018, 2017 and 2016 is as follows ($000):

Year Ended June 30, |  | 2018 |  |  | 2017 |  |  | 2016 |
Stock Options and Cash-Based Stock Appreciation Rights |  | $ | 6,605 |  |  | $ | 5,611 |  |  | $ | 4,309 |
Restricted Share Awards and Cash-Based Restricted Share Unit Awards |  |  | 7,850 |  |  |  | 6,799 |  |  |  | 4,401 |
Performance Share Awards and Cash-Based Performance Share Unit Awards |  |  | 5,221 |  |  |  | 3,626 |  |  |  | 2,196 |
|  | $ | 19,676 |  |  | $ | 16,036 |  |  | $ | 10,906 |

The share-based compensation expense is allocated approximately 20% to cost of goods sold and 80% to selling, general and administrative expense in the Consolidated Statements of Earnings, based on the employee classification of the grantee. Share-based compensation expense associated with liability awards was $4.4 million, $4.3 million, and $1.2 million, in the fiscal years ended June 30, 2018, 2017 and 2016, respectively.

Stock Options and Cash-Based Stock Appreciation Rights:

The Company utilized the Black-Scholes valuation model for estimating the fair value of stock option expense. During the fiscal years ended June 30, 2018, 2017 and 2016, the weighted-average fair value of options granted under the stock option plan was $14.23, $8.88 and $7.35, respectively, per option using the following assumptions:

Year Ended June 30, |  | 2018 |  |  | 2017 |  |  | 2016 |
Risk-free interest rate |  |  | 2.00 | % |  |  | 1.43 | % |  |  | 1.68 | %
Expected volatility |  |  | 37 | % |  |  | 37 | % |  |  | 38 | %
Expected life of options |  | 6.43 years |  |  | 6.28 years |  |  | 6.43 years |
Dividend yield |  | None |  |  | None |  |  | None |

The risk-free interest rate is derived from the average U.S. Treasury Note rate during the period, which approximates the rate in effect at the time of grant related to the expected life of the options. The risk-free interest rate shown above is the weighted average rate for all options granted during the fiscal year. Expected volatility is based on the historical volatility of the Company’s common stock over the period commensurate with the expected life of the options. The expected life calculation is based on the observed time to post-vesting exercise and/or forfeitures of options by our employees. The dividend yield of zero is based on the fact that the Company has never paid cash dividends and has no current intention to pay cash dividends in the future. The estimated annualized forfeitures are based on the Company’s historical experience of option pre-vesting cancellations and are estimated at a rate of 17.6%. The Company will record additional expense in future periods if the actual forfeiture rate is lower than estimated, and will adjust expense in future periods if the actual forfeitures are higher than estimated.

Stock option and cash-based stock appreciation rights activity during the fiscal year ended June 30, 2018 was as follows:

For our relative Total S hareholder Return (“TSR”) performance-based awards, which are based on market performance of our stock as compared to the Russel 2000 Index, the compensation cost is recognized over the performance period on a straight-line basis net of forfeitures, becaus e the awards vest only at the end of the measurement period and the probability of actual shares expected to be earned is considered in the grant date valuation. As a result, the expense is not adjusted to reflect the actual shares earned. We estimate the fair value of the TSR performance-based awards using the Monte-Carlo simulation model.

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 June 30, 2018, 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.

In February 2016, the Company entered into a contingent earnout arrangement which 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 for the achievement of each specific annual target over the next three years. The Company paid the first year earnout amount of $2.0 million during the year ended June 30, 2017.

In June 2017, the Company entered into a contingent earnout arrangement which 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 relating to finance, information technology and human resources, which if earned, would be payable for the achievement of each specific annual target over the next year.

In November 2017, the Company acquired a 93.8% equity investment in a privately held company. 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 their outstanding interests at any time on or after the third anniversary of the investment, or earlier upon certain events. 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 Liabilities” in the Consolidated Balance Sheet as of the acquisition date in accordance with ASC 815-10, Derivatives and Hedging. The fair value of the net put option is adjusted as necessary on a quarterly basis with any changes in the fair value recorded through earnings. The change in fair value of the net purchase option from the investment date to June 30, 2018 was not material.

The fair values of these contingent earnout arrangements and the net put option were measured using valuations based on other unobservable inputs that are significant to the fair value measurement (Level 3).

The Company estimated the fair value of the 0.25% convertible notes based on quoted market prices as of the last trading day prior to June 30, 2018; however, the convertible notes have only a limited trading volume and, as such, this fair value estimate is not necessarily the value at which the convertible notes could be retired or transferred. The Company concluded that this fair value measurement should be categorized within Level 2. The carrying value of the convertible notes is net of unamortized discount and issuance costs. See Note 7. Debt for details on the Company’s debt facilities. The fair value and carrying value of the convertible notes were as follows at June 30, 2018 ($000):

| Fair Value |  |  | Carrying Value |
Convertible notes | $ | 388,125 |  |  | $ | 288,591 |

The following tables provide a summary by level of the fair value of financial instruments that are measured on a recurring basis as of June 30, 2018 and 2017 ($000):

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 fiscal years 2018 and 2017.

The following table presents a reconciliation of the beginning and ending fair value measurements of the Company’s level 3 contingent earnout arrangements related to the acquisitions of II-VI EpiWorks and IPI and the net put option relating to the purchase of the equity investment in November 2017. ($000):

Net put option |  | 2,233 |
Changes in fair value recorded in other expense (income), net |  | (564 | )
Balance at June 30, 2018 | $ | 7,429 |

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 includes both variable and fixed interest rates, non-interest bearing debt and a capital lease obligation and are considered Level 2 among the fair value hierarchy and accordingly their carrying amounts approximate fair value.

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. These contracts are entered into 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 value of these contracts in the Company’s financial statements. These contracts had a total notional amount of $12.0 million and $12.7 million at June 30, 2018 and 2017, respectively. As of June 30, 2018, these forward contracts had expiration dates ranging from July 2018 through October 2018, with Japanese Yen denominations individually between 250 million and 500 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 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 prepaid and other current assets in the Company’s Consolidated Balance Sheets as of June 30, 2018. The change in the fair value of these contracts for the fiscal year ended June 30, 2018, 2017 and 2016 was insignificant.

Note 15. | Employee Benefit Plans

Eligible U.S. employees of the Company participate in a profit sharing retirement plan. Contributions accrued for the plan are made at the discretion of the Company’s board of directors and were $5.0 million, $4.3 million, and $3.4 million for the years ended June 30, 2018, 2017 and 2016, respectively.

The Company has an employee stock purchase plan available for employees who have completed six months of continuous employment with the Company. The employee may purchase the Company’s common stock at 5% below the prevailing market price. The amount of shares which may be bought by an employee during each fiscal year is limited to 10% of the employee’s base pay. This plan, as amended, limits the number of shares of common stock available for purchase to 1,600,000 shares. There were 462,798 and 477,949 shares of common stock available for purchase under the plan at June 30, 2018 and 2017, respectively.

Switzerland Defined Benefit Plan

In conjunction with the acquisition of II-VI Laser Enterprise in fiscal year 2014, the Company assumed a pension plan covering employees of our Swiss subsidiary (the “Swiss Plan”). Employer and employee contributions are made to the Swiss Plan based on various percentages of salary and wages that vary according to employee age and other factors. Employer contributions to the Swiss Plan for years ended June 30, 2018 and 2017 were $2.7 million and $2.4 million, respectively. Expected employer contributions in fiscal year 2019 are $2.7 million.

The changes in the funded status of the Swiss Plan during the fiscal years ended June 30, 2018 and 2017 were as follows:

Year Ended June 30, |  | 2018 |  |  | 2017 |

Net periodic pension cost associated with the Swiss Plan included the following components:

Year Ended June 30, |  | 2018 |  |  | 2017 |  |  | 2016 |
Service cost |  | $ | 3,766 |  |  | $ | 3,689 |  |  | $ | 2,680 |
Interest cost |  |  | 424 |  |  |  | 163 |  |  |  | 434 |

Net actuarial loss and prior service credit |  |  | 203 |  |  |  | 594 |  |  |  | (234 | )
Net periodic pension cost |  | $ | 5,242 |  |  | $ | 3,704 |  |  | $ | 1,783 |

The projected and accumulated benefit obligations for the Swiss Plan were calculated as of June 30, 2018 and 2017 using the following assumptions:

June 30, |  | 2018 |  |  | 2017 |
Discount rate |  |  | 0.9 | % |  |  | 0.8 | %
Salary increase rate |  |  | 2.0 | % |  |  | 2.0 | %

The net periodic pension cost for the Swiss Plan was calculated during the fiscal years ended June 30 2018, 2017, and 2016 using the following assumptions:

Year Ended June 30, |  | 2018 |  |  | 2017 |  |  | 2016 |
Discount rate |  |  | 0.8 | % |  |  | 0.3 | % |  |  | 1.1 | %
Salary increase rate |  |  | 2.0 | % |  |  | 2.0 | % |  |  | 2.0 | %
Expected return on plan assets |  |  | 2.0 | % |  |  | 2.0 | % |  |  | 2.0 | %

The discount rate is based on assumed pension benefit maturity and estimates developed using the rate of return and yield curves for high quality Swiss corporate and government bonds. The salary increase rate is based on our best assessment for on-going increases over time. The expected long-term rate of return on plan assets is based on the expected asset allocation, taking into consideration historical long-term rates of return for the relevant asset categories.

As is customary with Swiss pension plans, the assets of the plan are invested in a collective fund with multiple employers. We have no investment authority over the assets of the plan, which are held and invested by a Swiss insurance company. The investment strategy of the Swiss Plan is managed by an independent asset manager with the objective of achieving a consistent long-term return which will provide sufficient funding for future pension obligations while limiting risk.

The Swiss Plan is legally separate from II-VI, as are the assets of the plan. As of June 30, 2018, the Swiss Plan’s asset allocation was as follows (all of which are categorized as Level 2 in the fair value hierarchy):

June 30, |  | 2018 |  |  | 2017 |
Fixed income investments |  |  | 12.0 | % |  |  | 10.0 | %
Equity investments |  |  | 50.0 | % |  |  | 52.0 | %
Real estate |  |  | 31.0 | % |  |  | 26.0 | %
Cash |  |  | 4.0 | % |  |  | 9.0 | %
Other |  |  | 3.0 | % |  |  | 3.0 | %
|  |  | 100.0 | % |  |  | 100.0 | %

Estimated future benefit payments under the Swiss Plan are estimated to be as follows:

Year Ending June 30, |  |  |  |
($000) |  |  |  |
2019 |  | $ | 5,100 |
2020 |  |  | 1,800 |
2021 |  |  | 2,700 |
2022 |  |  | 2,900 |
2023 |  |  | 3,200 |
Next five years |  |  | 22,400 |

Other Employee Benefit Plans

The Company has no program for post-retirement health and welfare benefits.

The II-VI Incorporated Deferred Compensation Plan (the “Compensation Plan”) is designed to allow officers and key employees of the Company to defer receipt of compensation into a trust fund for retirement purposes. Under the Compensation Plan, as it is currently implemented by the Company, eligible participants can elect to defer up to 100% of certain discretionary incentive compensation and certain equity awards into the Compensation Plan. The Compensation Plan is a nonqualified, defined contribution employees’ retirement plan. At the Company’s discretion, the Compensation Plan may be funded by the Company making contributions based on compensation deferrals, matching contributions and discretionary contributions. Compensation deferrals will be based on an election by the participant to defer a percentage of compensation under the Compensation Plan. All assets in the Compensation Plan are subject to claims of the Company’s creditors until such amounts are paid to the Compensation Plan participants. Employees of the Company made contributions to the Compensation Plan in the amounts of approximately $1.1 million, $0.8 million, and $1.2 million for the fiscal years ended June 30, 2018, 2017, and 2016, respectively. There were no employer contributions made to the Compensation Plan for the fiscal year ended June 30, 2016.

Note 16. | Other Accrued Liabilities

The components of other accrued liabilities were as follows:

June 30, |  | 2018 |  |  | 2017 |

Note 17. | Commitments and Contingencies

The Company has purchase commitments for materials and supplies as part of the ordinary conduct of business. A portion of the commitments are long-term and are based on minimum purchase requirements. Certain short-term raw material purchase commitments have a variable price component which is based on market pricing at the time of purchase. Due to the proprietary nature of some of the Company’s materials and processes, certain contracts may contain liquidated damage provisions for early termination. The Company does not believe that a significant amount of liquidated damages are reasonably likely to be incurred under these commitments based upon historical experience and current expectations. The Company also has commitments relating to earnout arrangements on its prior year acquisitions of $5.4 million and $85.0 million for the planned acquisition of CoAdna. Inc., for fiscal year 2019. Total future commitments are as follows:

Year Ending June 30, |  |  |  |
($000) |  |  |  |
2019 |  | $ | 114,307 |
2020 |  |  | 3,477 |

Note 18. | Share Repurchase Programs

In August 2017, in conjunction with the Company’s offering and sale of the Notes, the Company’s Board of Directors authorized the Company to purchase up to $50 million of its common stock with a portion of the net proceeds received from the offering and sale of the Notes. The shares that were purchased by the Company pursuant to this authorization were retained as treasury stock and are available for general corporate purposes. The Company purchased 1,414,900 shares of its common stock for approximately $49.9 million pursuant to this authorization in fiscal 2018.

In August 2014, the Company’s Board of Directors authorized the Company to purchase up to $50 million of its common stock through a share repurchase program (the “Program”) that calls for shares to be purchased in the open market or in private transactions from time to time. The Program has no expiration and may be suspended or discontinued at any time. Shares purchased by the Company are retained as treasury stock and available for general corporate purposes. The Company did not repurchase shares pursuant to this Program during the fiscal years ended June 30, 2018 and 2017. During the fiscal year ended June 30, 2016, the Company purchased 380,538 shares of its common stock for $6.3 million under this program. Through June 30, 2018, the Company has cumulatively purchased 1,316,587 shares of its common stock pursuant to the Program for approximately $19.0 million.

Note 19. | Accumulated Other Comprehensive Income (Loss)

The current and long-term portion of the capital lease obligation was recorded in Other accrued liabilities and Other liabilities, respectively, in the Company’s Consolidated Balance Sheets as of June 30, 2018 and 2017. The present value of the minimum capital lease payments at inception was $25.0 million recorded in Property, Plant & Equipment, net, in the Company’s Consolidated Balance Sheet, with assoc iated depreciation being recorded over the 15 year life of the lease. During the fiscal year ended June 30, 2018, the Company recorded $1.7 million of depreciation expense associated with the capital leased asset.
