Item 1. Business.

THE COMPANY

RPM International Inc., a Delaware corporation, succeeded to the reporting obligations of RPM, Inc., an Ohio corporation, following a 2002 reincorporation transaction. RPM, Inc. was incorporated in 1947 under the name Republic Powdered Metals, Inc. and changed its name to RPM, Inc. in 1971. In connection with the 2002 reincorporation from Ohio to Delaware, we established a new legal structure, which included the formation of two new, wholly owned subsidiaries of RPM International Inc., the RPM Consumer Holding Company and the RPM Industrial Holding Company. These two holding companies, in addition to RPM, Inc., which remained as one of our subsidiaries following the reincorporation, own the various operating companies and other legal entities that make up RPM International Inc. In 2010, RPM, Inc. changed its name to Specialty Products Holding Corp (“SPHC”). At the end of fiscal 2010, SPHC and its Bondex International, Inc. (“Bondex”) subsidiary filed voluntary Chapter 11 bankruptcy petitions, as a result of which we deconsolidated SPHC and its subsidiaries from our financial results at that time. As of January 1, 2015, we reconsolidated such subsidiaries as they emerged from bankruptcy. See Item 3 — “Legal Proceedings” and Notes A(2) and G to the Consolidated Financial Statements for additional information.

As used herein, the terms “RPM,” the “Company,” “we,” “our” and “us” refer to RPM International Inc. and all of our consolidated subsidiaries, unless the context indicates otherwise. Our principal executive offices are located at 2628 Pearl Road, P.O. Box 777, Medina, Ohio 44258, and our telephone number is (330) 273-5090.

BUSINESS

Our subsidiaries manufacture, market and sell various specialty chemical product lines, including high-quality specialty paints, protective coatings, roofing systems, sealants and adhesives, focusing on the maintenance and improvement needs of both the industrial and consumer markets. Our family of products includes those marketed under brand names such as API, Carboline, CAVE, DAP, Day-Glo, Dri-Eaz, Dryvit, Euclid, EUCO, Fibergrate, Flecto, Flowcrete, Grupo PV, Hummervoll, illbruck, Mohawk, Rust-Oleum, Stonhard, TCI, Toxement, Tremco, Tuf-Strand, Universal Sealants, Viapol, Watco and Zinsser. As of May 31, 2015, our subsidiaries marketed products in approximately 170 countries and territories and operated manufacturing facilities in approximately 116 locations in the United States, Argentina, Australia, Belgium, Brazil, Canada, Chile, China, Colombia, France, Germany, India, Italy, Malaysia, Mexico, The Netherlands, New Zealand, Norway, Poland, Saudi Arabia, South Africa, Spain, Sweden, Turkey, the United Arab Emirates and the United Kingdom. Approximately 40% of our sales are generated in international markets through a combination of exports and direct sales in foreign countries. For the fiscal year ended May 31, 2015, we recorded net sales of $4.6 billion.

Available Information

Our Internet website address is www.rpminc.com. We make available free of charge on or through our website our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, and amendments to these reports, as soon as reasonably practicable after such reports are electronically filed with, or furnished to, the Securities and Exchange Commission.

Segment Information

Our business is divided into two reportable segments: the industrial reportable segment (“industrial segment”) and the consumer reportable segment (“consumer segment”). Within each reportable segment, we aggregate several operating segments which comprise individual reporting units and product lines that generally

address common markets, utilize similar technologies and are able to share manufacturing or distribution capabilities. The industrial segment (Tremco Group, tremco illbruck Group, RPM Performance Coatings Group, RPM2-Industrial Group and SPHC Group), which comprises approximately 65% of our total net sales, includes maintenance and protection products for roofing and waterproofing systems, flooring, corrosion control and other specialty applications. The consumer segment (Rust-Oleum Group, DAP Group and RPM2-Consumer Group,) comprises approximately 35% of our total net sales and includes rust-preventative, special purpose and decorative paints, caulks, sealants, primers, nail enamels, cement and woodcare coatings and other branded consumer products. See Note P, “Segment Information,” of the Notes to Consolidated Financial Statements, which appears in the 2015 Annual Report to Stockholders, and is incorporated herein by reference, for financial information relating to our two reportable segments and financial information by geographic area.

On May 31, 2010, Bondex International, Inc. and its parent, SPHC, voluntarily filed Chapter 11 reorganization proceedings in the United States Bankruptcy Court for the District of Delaware. SPHC is our wholly owned subsidiary. In accordance with Accounting Standards Codification (“ASC”) 810, when a subsidiary becomes subject to the control of a government, court, administrator, or regulator, deconsolidation of that subsidiary is generally required. We had therefore deconsolidated SPHC and its subsidiaries from our balance sheet as of May 31, 2010, and had eliminated the results of SPHC’s operations from our results of operations beginning on that date. Effective as of December 23, 2014, the United States Bankruptcy Court in Delaware and the United States District Court in Delaware confirmed the Bankruptcy Plan for SPHC and related entities and these entities emerged from bankruptcy. Accordingly, financial results of SPHC’s operating subsidiaries, which have not been included in our financial reports since the bankruptcy filing, have been reconsolidated with our results as of January 1, 2015, and will be included in our results going forward. As a result, SPHC and its subsidiaries is reflected as an additional operating segment within the industrial reportable segment, beginning with our fiscal 2015 third quarter results.

In addition, we receive license fees and royalty income from numerous international license agreements, and we also have several joint ventures, which are accounted for under the equity method, operating in various foreign countries. We have manufacturing facilities in Argentina, Australia, Belgium, Brazil, Canada, Chile, China, Colombia, France, Germany, India, Italy, Malaysia, Mexico, The Netherlands, New Zealand, Norway, Poland, Saudi Arabia, South Africa, Spain, Sweden, Turkey, the United Arab Emirates and the United Kingdom. We also have sales offices or warehouse facilities in Austria, The Czech Republic, Egypt, Finland, Hong Kong, Hungary, Indonesia, Japan, Kuwait, Oman, Portugal, Qatar, Russia, Singapore, Switzerland, Thailand, Vietnam and several other countries. Information concerning our foreign operations is set forth in Management’s Discussion and Analysis of Results of Operations and Financial Condition, which appears in the 2015 Annual Report to Stockholders, and is incorporated herein by reference.

Competition

We conduct our business in highly competitive markets, and all of our major products face competition from local, regional and national firms. Our markets, however, are fragmented, and we do not face competition across all of our products from any one competitor in particular. Several of our competitors have access to greater financial resources and larger sales organizations than we do. While third-party figures are not necessarily available with respect to the size of our position in the market for each of our products, we believe that we are a major producer of caulks, sealants, patch-and-repair products for the general consumer as well as for the residential building trade; roofing systems; urethane sealants and waterproofing materials; aluminum coatings; cement-based paints; hobby paints; industrial-corrosion-control products; fireproofing; consumer rust-preventative coatings; polymer floorings; fluorescent coatings and pigments; fiberglass-reinforced-plastic gratings; nail polish; water and fire damage restoration products; carpet cleaning systems and shellac-based coatings. However, we do not believe that we have a significant share of the total protective coatings market (on a world-wide basis). The following is a summary of the competition that our key products face in the various markets in which we compete:

Paints, Coatings, Adhesives and Sealants Products

The market for paints, coatings, adhesives and sealants has experienced significant consolidation over the past several decades. However, the market remains fragmented, which creates further consolidation opportunities for industry participants. Many leading suppliers tend to focus on coatings, while other companies focus on adhesives and sealants. Barriers to market entry are relatively high for new market entrants due to the lengthy intervals between product development and market acceptance, the importance of brand identity and the difficulty in establishing a reputation as a reliable supplier of these products. Most of the suppliers, including us, who provide these items have a portfolio of products that span across a wide variety of applications.

Consumer Home Improvement Products. Within the consumer segment, we generally serve the home improvement market with products designed for niche architectural, rust-preventative, decorative, special purpose, caulking and sealing applications. The products we sell for home improvement include those sold under our DAP, Phenoseal, Rust-Oleum, Watco and Zinsser brand names. Leading manufacturers of home improvement-related coatings, adhesives and sealants market their products to DIY users and contractors through a wide range of distribution channels. These distribution channels include direct sales to home improvement centers, mass merchandisers, hardware and paint stores, and sales through distributors and sales representative organizations. Competitors in this market generally compete for market share by marketing and building upon brand recognition, providing customer service and developing new products based on customer needs.

Industrial Protective Coatings Products. Anti-corrosion protective coatings and fireproofing must withstand the destructive elements of nature and operating processes under harsh environments and conditions. Some of the larger consumers of high-performance protective and corrosion control coatings and fireproofing are the oil and gas, pulp and paper, petrochemical, shipbuilding, public utility and bridge and highway industries. In the public sector, corrosion control coatings are used on structures such as bridges and in water and wastewater treatment plants. These markets are highly fragmented. We and our competitors compete for market share by supplying a wide variety of high-quality products and by offering customized solutions. Our industrial coating products are marketed primarily under our Carboline, Plasite, Nullifire, A/D Fire, Thermo-lag, Perlifoc and Epoplex brand names.

Roofing Systems Products

In the roofing industry, re-roofing applications have historically accounted for three-quarters of U.S. demand, with the remaining quarter generated by new roofing applications. The largest manufacturers of roofing systems products focus primarily on residential roofing as well as single-ply systems for low-end, commercial and institutional applications, competing mainly on price and, to a lesser degree, service. In contrast, we compete primarily for the higher-end, multi-ply and modified bitumen applications in the built-up and low-slope roofing industry. This specialty niche within the larger market tends to exhibit fewer commodity-market characteristics, with customers valuing the greater protection and longer life provided by these roofing systems, as well as ongoing maintenance, inspection and technical services. Our roofing systems are primarily marketed under our Tremco brand. Historically, our typical roofing systems customers have included governmental facilities, universities, schools, hospitals, museums and certain manufacturing facilities. However, we are also very active in the growing market of sustainable roofing systems, and our Tremco Roofing fluid applied and restoration coating systems represent our fastest growing product segment. Our restoration systems meet sustainable objectives including energy efficiency through reflectivity and emissivity, and eliminate environmentally and economically costly landfill waste.

Construction Chemical Products

Flooring Systems Products. Polymer flooring systems are used in industrial, commercial and, to a lesser extent, residential applications to provide a smooth, seamless surface that is impervious to penetration by water and other substances while being easy to clean and maintain. These systems are particularly well-suited for clean environments such as pharmaceutical, food and beverage and healthcare facilities. In addition, the fast installation time and long-term durability of these systems and products make them ideal for industrial floor repair and restoration. Polymer flooring systems are based on epoxy, polyurethane and methylmethacrylate resins. Most of these flooring systems are applied during new construction, but there is also a significant repair and renovation market. Key performance attributes in polymer flooring systems that distinguish competitors for these applications include static control, chemical resistance, contamination control, durability and aesthetics. We market our flooring systems under the Stonhard, Flowcrete, Expanko, Fritztile, Hummervoll and API brand names.

FRP Grating and Structural Composites. Fiberglass reinforced plastic grating, or FRP, is used primarily in industrial and, to a lesser extent, commercial applications. FRP grating exhibits many specialized features, which make it a beneficial alternative to traditional steel or aluminum grating. These include a high strength-to-weight ratio, high corrosion resistance, electrical and thermal non-conductivity, and molded-in color, which eliminates the need for repainting. FRP grating is used for platforms, walkways, stairs and structures for a variety of applications, including those in the food and beverage, chemical processing, water-wastewater, pulp and paper, and offshore oil and gas industries. Other structural composites include trench drains, channel drains, curbing and structural members. Key attributes that differentiate competitors in these markets include product quality, depth of product line, and design-and-fabrication services. Our products for these applications are sold under our Fibergrate, Chemgrate, Corgrate, Safe-T-Span, EnviroKerb, EnviroChannel, EnviroDeck and EnviroGrate brand names.

Sealants, Waterproofing, Concrete and Masonry Products. Sealants, which are used primarily for commercial buildings, include urethane, silicone, latex, butyl and hybrid technology products, and are designed to be installed in construction joints for the purpose of providing an air and water-tight seal. Waterproof coatings,

usually urethane or asphalt based, are installed in exposed and buried applications to waterproof and protect concrete. Structural and traffic bearing membranes are used in a variety of applications for bridge deck construction and restoration and the protection and preservation of balconies, pedestrian walkways and parking structures. In the concrete and masonry additives market, a variety of chemicals and fibers can be added to concrete and masonry to improve the processability, performance, or appearance of these products. Chemical admixtures for concrete are typically grouped according to their functional characteristics, such as water-reducers, set controllers, superplasticizers and air-entraining agents. Curing and sealing compounds, structural grouts, epoxy adhesives, floor hardeners and toppings, joint fillers, industrial and architectural coatings, decorative color/stains/stamps, and a comprehensive selection of restoration materials are used to protect, repair or improve new or existing concrete structures used in the construction industry. The key attributes that differentiate competitors for these applications include quality assurance, on-the-job consultation and value-added, highly engineered products. We primarily offer products marketed under our Tremco, EUCO, Toxement, Viapol, Betumat, CAVE, illbruck, Tamms, Republic, Vulkem, Dymeric, Increte, TUFF-N-DRI, Nufins, StructureCare, BridgeCare, Pitchmastic, Watchdog Waterproofing, PSI, Tuf-Strand and Enviro-Dri brand names for this line of business.

Intellectual Property

Our intellectual property portfolios include valuable patents, trade secrets and know-how, domain names, trademarks, trade and brand names. In addition, through our subsidiaries, we continue to conduct significant research and technology development activities. Among our most significant intangibles are our Rust-Oleum^®, Carboline^®, DAP^®, illbruck^® and Tremco^® trademarks.

Rust-Oleum Brands Company and some of our other subsidiaries own more than 1,000 trademark registrations or applications in the United States and numerous other countries for the trademark “Rust-Oleum^®” and other trademarks covering a variety of rust-preventative, decorative, general purpose, specialty, industrial and professional coatings sold by Rust-Oleum Corporation and related companies.

Carboline Company and some of our other subsidiaries own more than 240 other trademark registrations or applications in the United States and numerous other countries covering the products sold by the Carboline Company and related companies, including two United States trademark registrations for the trademark “Carboline^®”.

DAP Brands Company and other subsidiaries of the Company own more than 410 trademark registrations or applications in the United States and numerous other countries for the “DAP^®” trademark, the “Putty Knife design” trademark and other trademarks covering products sold under the DAP brand and related brands.

Tremco Incorporated and some of our other subsidiaries own more than 85 registrations for the trademark “Tremco^®” in the United States and numerous countries covering a variety of roofing, sealants and coating products. There are also many other trademarks of Tremco Incorporated and some of our other subsidiaries that are the subject of registrations or applications in the United States and numerous other countries, bringing the total number of registrations and applications covering products sold under the Tremco brand and related brands to more than 500.

Our other principal product trademarks include: AlphaGuard^®, Alumanation^®, Betumat^®, B-I-N^®, Bitumastic^®, Bulls Eye 1-2-3^®, Chemgrate^®, Dri-Eaz, Dymonic^®, Enviro-Dry^®, EUCO^®, ExoAir^®, Expanko^®, Flecto^®, Fibergrate^®, Floquil^®, Fritztile^®, Paraseal^®, Permaroof^®, Plasite^®, Proglaze^®, Sanitile^®, Solargard^®, Spectrem^®, Stonblend^®, Stonclad^®, Stonhard^®, Stonlux^®, Stonshield^®, Testors^®, TREMproof^®, TUFF-N-DRI^®, Varathane^®, Viapol^®, Vulkem^®, Watchdog Waterproofing^®, Woolsey^®, Zinsser^® and Z-Spar^®; and, in Europe, API™, Perlifoc^®, Hummervoll^®, USL^®, Nufins^®, Pitchmastic^®, Visul^®, Flowcrete^tm, Nullifire™, Radglo™ and Martin Mathys^tm. Our trademark registrations are valid for a variety of different terms of up to 20 years, and may be renewable as long as the trademarks continue to be used and all other local conditions for renewal are met. Our trademark registrations are maintained and renewed on a regular basis as required.

Raw Materials

The sources and availability of the raw materials we use in our business continue to be adequate to meet our current and projected needs. While certain oil-based raw material cost have eased over the past 12 months, our material costs can experience significant (and usually volatile) cost changes due to changes in global demand, unusually high planned and unplanned raw material production shutdowns, certain changes in global crop yields, certain changing feedstock costs, foreign exchange effects, supplier consolidation and related pricing discipline, and decreased natural gas costs relative to the cost of oil, which has caused cracking optimization and, therefore, a reduction in the supply of certain materials. In particular, foreign exchange has had a significant impact recently upon the costs of sales, since several of our foreign operations use the U.S. dollar, which has strengthened recently, to pay certain suppliers of finished goods and/or raw materials. On a long-term basis, we anticipate the costs of the raw materials we use will continue to be subject to upward pressure.

Seasonal Factors

Our business is dependent, to a significant extent, on external weather factors. We historically experience stronger sales and net income in our first, second and fourth fiscal quarters, which are the three month periods ending August 31, November 30 and May 31, respectively, while we have experienced weaker performance in our third fiscal quarter.

Customers

Ten large consumer segment customers, such as DIY home centers, on a combined basis represented approximately 23%, 24% and 22% of our total net sales for the fiscal years ended May 31, 2015, 2014 and 2013, respectively. Except for sales to these customers, our business is not dependent upon any one customer or small group of customers, but is largely dispersed over a substantial number of customers.

We historically have not had a significant backlog of orders, and we did not have a significant backlog at May 31, 2015.

Research and Development

Our research and development work is performed at various laboratory locations. During fiscal years 2015, 2014 and 2013, we spent approximately $56.7 million, $54.6 million and $49.3 million, respectively, on research and development activities. In addition to this laboratory work, we view our field technical service as being integral to the success of our research activities. Our research and development activities and our field technical service costs are both included as part of our selling, general and administrative expenses.

Environmental Matters

We are subject to a broad range of laws and regulations dealing with environmental, health and safety issues for the various locations around the world in which we conduct our business. These laws and regulations include, but are not limited to, the following major areas:

•

the sale, export, generation, storage, handling, use and transportation of hazardous materials;

•

the emission and discharge of hazardous materials into the soil, water and air; and

•

the health and safety of our employees.

We are also required to obtain permits from various governmental authorities for certain operations. We cannot guarantee that our subsidiaries or their plants have been or will be at all times in complete compliance with all such laws, regulations and permits. If we, or any of our subsidiaries, violate or fail to comply with these laws, regulations or permits, we could be fined or otherwise sanctioned by regulators.

Certain environmental laws assess liability on current or previous owners or operators of real property for the cost of removal or remediation of hazardous substances. Persons who arrange for the disposal or treatment of hazardous substances also may be responsible for the cost of removal or remediation of these substances, even if such persons never owned or operated any disposal or treatment facility. Certain of our subsidiaries are involved in various environmental claims, proceedings and/or remedial activities relating to facilities currently or previously owned, operated or used by these subsidiaries, or their predecessors. In addition, we or our subsidiaries, together with other parties, have been designated as potentially responsible parties, or PRPs, under federal and state environmental laws for the remediation of hazardous waste at certain disposal sites. In addition to clean-up actions brought by federal, state and local agencies, plaintiffs could raise personal injury, natural resource damage or other private claims due to the presence of hazardous substances on a property. Environmental laws often impose liability even if the owner or operator did not know of, or was not responsible for, the release of hazardous substances.

We have incurred in the past, and will continue to incur in the future, costs to comply with environmental laws. Environmental laws and regulations are complex, change frequently and have tended to become increasingly stringent over time. In addition, the related costs may vary depending on the particular facts and development of new information. As a result, our operating expenses and continuing capital expenditures related to compliance with environmental laws may increase, and more stringent standards also may limit our operating flexibility. A significant increase in these costs and capital expenditures could adversely affect our business, results of operations, financial condition or cash flows. In addition, to the extent hazardous materials exist on or under our real property, the value and future use of that real property may be adversely affected. For information regarding environmental accruals, see Note O, “Contingencies and Other Accrued Losses,” of the Notes to our Consolidated Financial Statements, which appears in the 2015 Annual Report to Stockholders, and is incorporated herein by reference. For more information concerning certain environmental matters affecting us, see “Item 3 — Legal Proceedings — Environmental Proceedings” in this Annual Report on Form 10-K.

Employees

As of May 31, 2015, we employed 12,864 persons, of whom approximately 914 were represented by unions under contracts which expire at varying times in the future. We believe that all relations with employees and their unions are good.

Item 1A. Risk Factors.

You should carefully consider the following risks, as well as the other information contained or incorporated by reference in this Annual Report on Form 10-K, in evaluating us, our business and your investment in us.

We are the subject of an ongoing SEC investigation, which could divert management’s focus, result in substantial investigation expenses and have an adverse impact on our reputation and financial condition and results of operations.

We were notified by the SEC on June 24, 2014 that we are the subject of a formal investigation pertaining to the timing of our disclosure and accrual of loss reserves in fiscal 2013 with respect to the previously disclosed GSA and DOJ investigation into compliance issues relating to Tremco Roofing Division’s GSA contracts. We are cooperating with the SEC in its ongoing investigation and continue to be engaged in discussions with the staff of the Division of Enforcement concerning potential issues arising out of the SEC’s investigation. As previously disclosed, our audit committee completed an investigation into the facts and circumstances surrounding the timing of our disclosure and accrual of loss reserves with respect to the GSA and DOJ investigations, and determined to restate our financial results for the first, second and third quarters of fiscal 2013.

We have incurred significant legal and accounting expenditures in connection with the SEC’s investigation. We are unable to predict how long the SEC’s investigation will continue or whether, at the conclusion of its

investigation, the SEC will seek to impose fines or take other actions against us. Any action by the SEC could result in sanctions against us and/or certain of our officers. A protracted investigation could impose substantial additional costs and distractions, regardless of its outcome. Furthermore, publicity surrounding the foregoing or any enforcement action as a result of the SEC’s investigation, even if ultimately resolved favorably for us, could have an adverse impact on our reputation, business, financial condition, results of operations or cash flows.

Our operations have been adversely affected by global market and economic conditions.

Global economic uncertainty continues to exist. Our operations could be adversely affected by global economic conditions if global markets were to decline in the future. Any future economic declines may result in decreased revenue, gross margin, earnings or growth rates and difficulty in managing inventory levels and collection of customer receivables. We also have experienced, and expect to continue to experience, increased competitive pricing pressure. In addition, customer difficulties in the future could result in decreases in product demand, increases in bad debt write-offs, decreases in timely collection of accounts receivable and adjustments to our allowance for doubtful accounts receivable.

Global economic and capital market conditions may cause our access to capital to be more difficult in the future and/or costs to secure such capital more expensive.

We may need new or additional financing in the future to provide liquidity to conduct our operations, expand our business or refinance existing indebtedness. Any sustained weakness in general economic conditions and/or U.S. or global capital markets could adversely affect our ability to raise capital on favorable terms or at all. From time to time we have relied, and we may also rely in the future, on access to financial markets as a source of liquidity for working capital requirements, acquisitions and general corporate purposes. Our access to funds under our credit facility is dependent on the ability of the financial institutions that are parties to that facility to meet their funding commitments. Those financial institutions may not be able to meet their funding commitments if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests within a short period of time. Moreover, the obligations of the financial institutions under our credit facility are several and not joint and, as a result, a funding default by one or more institutions does not need to be made up by the others. Longer term volatility and continued disruptions in the capital and credit markets as a result of uncertainty, changing or increased regulation of financial institutions, reduced alternatives or failures of significant financial institutions could adversely affect our access to the liquidity needed for our businesses in the longer term. Such disruptions could require us to take measures to conserve cash until the markets stabilize or until alternative credit arrangements or other funding for our business needs can be arranged.

Volatility in the equity markets or interest rates could substantially increase our pension costs and required pension contributions.

We sponsor qualified defined benefit pension plans and various other nonqualified postretirement plans. The qualified defined benefit pension plans are funded with trust assets invested in a diversified portfolio of debt and equity securities and other investments. Among other factors, changes in interest rates, investment returns and the market value of plan assets can (i) affect the level of plan funding; (ii) cause volatility in the net periodic pension cost; and (iii) increase our future contribution requirements. A significant decrease in investment returns or the market value of plan assets or a significant decrease in interest rates could increase our net periodic pension costs and adversely affect our results of operations. A significant increase in our contribution requirements with respect to our qualified defined benefit pension plans could have an adverse impact on our cash flow.

The results of our annual testing of goodwill and other intangible assets have required, and in the future may require that we incur non-cash impairment charges.

As of May 31, 2015, we had approximately $1.8 billion in goodwill and other intangible assets. The Accounting Standards Codification (“ASC”) section 350 requires that goodwill be tested at least on an annual basis, or more frequently as impairment indicators arise, using either a qualitative assessment or a fair-value

approach at the reporting unit level. We perform our annual required impairment tests, which involve the use of estimates related to the fair market values of the reporting units with which goodwill is associated, as of the first day of our fourth fiscal quarter. The evaluation of our long-lived assets for impairment includes determining whether indicators of impairment exist, which is a subjective process that takes into account both internal and external factors. Impairment assessment requires the use of significant judgment with regard to estimates and assumptions surrounding future results of operations and cash flows. For the fiscal years ended May 31, 2015, 2014 and 2013, our impairment testing did not result in any impairment loss. In the future, if global economic conditions were to decline significantly, or if our reporting units experienced significant declines in business, we may incur substantial non-cash goodwill and other intangible asset impairment charges. The amount of any such impairment charge could have a material adverse effect on our results of operations.

Our significant amount of indebtedness could have a material adverse impact on our business.

Our total debt levels were approximately $1.7 billion and $1.4 billion at May 31, 2015 and 2014, respectively, which compares with $1.3 billion in stockholders’ equity at May 31, 2015. Our level of indebtedness could have important consequences. For example, it could:

•

require us to dedicate a material portion of our cash flow from operations to make payments on our indebtedness, thereby reducing the cash flow available to fund working capital, capital expenditures, acquisitions, dividend payments, stock repurchases or other general corporate requirements;

•

result in a downgrade of our credit rating, which would increase our borrowing costs, adversely affect our financial results, and make it more difficult for us to raise capital;

•

restrict our operational flexibility and reduce our ability to conduct certain transactions, since our credit facility contains certain restrictive financial and operating covenants;

•

limit our flexibility to adjust to changing business and market conditions, which would make us more vulnerable to a downturn in general economic conditions; and

•

have a material adverse effect on our short-term liquidity if large debt maturities occur in close succession.

We cannot assure you that our business always will be able to make timely or sufficient payments of our debt. Should we fail to comply with covenants in our debt instruments, such failure could result in an event of default which, if not cured or waived, would have a material adverse effect on us.

Fluctuations in the supply and prices of raw materials may negatively impact our financial results.

We obtain the raw materials needed to manufacture our products from a number of suppliers. Many of our raw materials are petroleum-based derivatives, minerals and metals. Under normal market conditions, these materials are generally available on the open market and from a variety of producers. From time to time, however, the prices and availability of these raw materials fluctuate, which could impair our ability to procure necessary materials or increase the cost of manufacturing our products. Although certain petroleum-based raw materials have eased lately, the costs of the raw materials we use are under generally upward pressure, over the longer term, due to escalating energy and related feedstock costs, increased levels of global demand, and improved levels of supplier pricing discipline. If the prices of raw materials continue to increase and we are unable to pass these increases on to our customers, we could experience reduced gross profit margins.

The markets in which we operate are highly competitive and some of our competitors are much larger than we are and may have greater financial resources than we do.

The markets in which we operate are fragmented, and we do not face competition from any one company across all of our product lines. However, any significant increase in competition, as a result of the consolidation of competitors or otherwise, may cause us to lose market share or compel us to reduce prices to remain competitive, which could result in reduced gross profit margins. Increased competition may also impair our

ability to grow or to maintain our current levels of revenues and earnings. Companies that compete in our markets include Akzo Nobel, Ferro, H.B. Fuller, Masco, PPG, Sherwin-Williams and Valspar. Several of these companies are much larger than we are and may have greater financial resources than we do. Increased competition with these companies could prevent the institution of price increases or could require price reductions or increased spending to maintain our market share, any of which could adversely affect our results of operations.

Our success depends upon our ability to attract and retain key employees and the succession of senior management.

Our success largely depends on the performance of our management team and other key employees. If we are unable to attract and retain talented, highly qualified senior management and other key people, our business, results of operations, cash flows and financial condition could be adversely affected. In addition, if we are unable to effectively provide for the succession of senior management, including our Chief Executive Officer, our business, results of operations, cash flows and financial condition may be adversely affected. While we follow a disciplined, ongoing succession planning process and have succession plans in place for senior management and other key executives, these do not guarantee that the services of qualified senior executives will continue to be available to us at particular moments in time.

We depend on a number of large customers for a significant portion of our net sales and, therefore, significant declines in the level of purchases by any of these key customers could harm our business.

Some of our operating companies, particularly in the consumer segment, face a substantial amount of customer concentration. Our key consumer segment customers include Ace Hardware, Canadian Tire, Cotter & Company, Do It Best, The Home Depot, Lowe’s, Menards, Orgill, Wal-Mart and W.W. Grainger. Sales to our ten largest consumer segment customers accounted for approximately 23%, 24% and 22% of our total net sales for the fiscal years ended May 31, 2015, 2014 and 2013, respectively, and 67%, 64% and 63%, respectively, of the consumer segment’s net sales for those same fiscal years. Sales to the Home Depot represented less than 10% of our consolidated net sales for fiscal 2013; 11% of our consolidated net sales for fiscal 2014 and 10% of our consolidated net sales for fiscal 2015; and 29%, 29% and 28% of our consumer segment net sales for fiscal 2015, 2014 and 2013, respectively. If we were to lose one or more of our key customers, or experience a delay or cancellation of a significant order, or incur a significant decrease in the level of purchases from any of our key customers, or experience difficulty in collecting amounts due from a key customer, our net revenues could decline materially and our operating results could be reduced materially.

Many of our customers operate in cyclical industries, and downward economic cycles may have a material adverse effect on our business.

Many of our customers, across both reportable segments, are in businesses and industries that are cyclical in nature and sensitive to changes in general economic conditions, interest rates, construction activity, and other factors, including changes in consumer spending and preferences. As a result, the demand for our products by these customers depends, in part, upon general economic conditions. Downward economic cycles affecting the markets of our customers may reduce the sales of our products resulting in material reductions to our revenues and net earnings.

A loss in the actual or perceived value of our brands could limit or reduce the demand for our products.

Our family of products includes a number of well-known brand names that are used in a variety of construction, industrial maintenance, consumer DIY and professional applications. We believe that continuing to maintain the strength of our brands is critical to increasing demand for our products and maintaining their widespread acceptance among our customers. The reputations of our branded products depend on numerous factors, including the successful advertising and marketing of our brand names, consumer acceptance, the availability of similar products from our competitors, and our ability to maintain our products’ quality and technological advantages. A loss in the actual or perceived value of our brands could limit or reduce the demand for our products.

Our business and financial condition could be adversely affected if we are unable to protect our material trademarks and other proprietary information.

We have numerous valuable patents, trade secrets and know-how, domain names, trademarks and trade names, including certain marks that are significant to our business, which are identified under Item 1 of this Annual Report on Form 10-K. Despite our efforts to protect our trademarks and other proprietary rights from unauthorized use or disclosure, other parties, including our former employees or consultants, may attempt to disclose, obtain or use our proprietary information or marks without our authorization. Unauthorized use of our trademarks, or unauthorized use or disclosure of our other intellectual property, could negatively impact our business and financial condition.

The chemical and construction products industries in which we operate expose us to inherent risks of legal and warranty claims and other litigation-related costs, which could adversely impact our business.

As a participant in the chemical and construction products industries, we face an inherent risk of exposure to legal claims in the event that the failure, use or misuse of our products results, or is alleged to result, in bodily injury and/or property damage. In the course of our business we are subject to a variety of inquiries and investigations by regulators, as well as claims and lawsuits by private parties including those related to product liability, asbestos, product warranty, environmental, contracts, intellectual property and commercial matters, which due to their uncertain nature may result in losses, some of which may be material. We offer warranties on many of our products, as well as long term warranty programs at certain of our businesses, and as a result, from time to time we may experience higher levels of warranty expense, which is typically reflected in selling, general and administrative expenses. The nature and extent to which we use hazardous or flammable materials in our manufacturing processes creates risk of damage to persons and property that, if realized, could be material.

Compliance with environmental laws and regulations could subject us to unforeseen future expenditures or liabilities, which could have a material adverse impact on our business.

We are subject to numerous environmental laws and regulations in the U.S., Canada and other countries where we conduct business. Governmental and regulatory authorities impose various laws and regulations on us that relate to environmental protection, the sale and export of certain chemicals or hazardous materials, and various health and safety matters, including the discharge of pollutants into the air and water, the handling, use, treatment, storage and clean-up of solid and hazardous wastes, the use of certain chemicals in product formulations, and the investigation and remediation of soil and groundwater affected by hazardous substances. These laws and regulations include the Clean Air Act, the Clean Water Act, RCRA, CERCLA, TSCA, and various other federal, state, provincial, local and international statutes. In addition, these laws and regulations often impose strict, retroactive and joint and several liability for the costs of, and damages resulting from, cleaning up our or our predecessors’ past or present facilities and third party disposal sites. We are currently undertaking remedial activities at a number of facilities and properties and have received notices under the federal Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) or analogous state laws of liability or potential liability in connection with the disposal of material from our current or former operations. Further, we also could be subject to future liability resulting from conditions that are currently unknown to us that could be discovered in the future.

The environmental laws under which we operate are numerous, complicated and often increasingly stringent, and may be applied retroactively. As a result, we have not always been and may not always be in full compliance with all environmental, health and safety laws and regulations in every jurisdiction in which we conduct our business. In addition, if we violate or fail to comply with environmental laws, we could be fined or otherwise sanctioned by regulators. We also could be liable for consequences arising out of human exposure to hazardous substances relating to our products or operations. Accordingly, we cannot guarantee that we will not be required to make additional expenditures to remain in or to achieve compliance with environmental laws in the future or that any such additional expenditures will not have a material adverse effect on our business, financial condition, results of operations or cash flows.

Our businesses are subject to extensive environmental, health and safety laws and regulations that may restrict or adversely impact our ability to conduct our business.

Our businesses are dependent on the issuance of operating permits and registrations required from government agencies. In connection with the performance of certain activities, our businesses are required to seek permission from agencies in the states, provinces, and countries in which they operate. If regulatory permits or registrations are delayed, restricted, or rejected, subsequent operations at our businesses could be delayed or restricted, which could have an adverse effect on our results of operations.

We expect that the environmental, health and safety laws and regulations applicable to our business will continue to become more stringent in the future which may result in increased costs to us for compliance therewith. Further, failure to comply with applicable environmental, health and safety laws and regulations or permit requirements could result in substantial civil or criminal fines and penalties or enforcement actions, including regulatory or judicial orders enjoining or curtailing operations, remedial or corrective measures, installations of pollution control equipment, or other actions. This could have a material adverse effect on our business, financial condition and operating results.

Our businesses are subject to varying domestic and foreign laws and regulations that may restrict or adversely impact our ability to conduct our business.

Our businesses are subject to varying domestic and foreign laws and regulations that may restrict or adversely impact our ability to conduct our business. These include securities, environmental, tax, competition and anti-trust, trade controls, data security, employment and privacy laws and regulations. These laws and regulations change from time to time and thus may result in increased costs to us related to our compliance therewith. From time to time regulators review our compliance with applicable laws. Enforcement actions, fines and private litigation claims and damages occur, notwithstanding our belief that we have in place appropriate risk management and compliance programs to mitigate these risks.

We from time-to-time experience compliance issues in foreign jurisdictions.

From time to time, we experience compliance issues and are the subject of governmental investigations in foreign jurisdictions. Compliance with laws and regulations applicable to our international operations increases our cost of doing business in foreign jurisdictions. We may be unable to keep current with changes in foreign government requirements and laws as they change from time to time. Failure to comply with these regulations could have adverse effects on our business. In many foreign countries it is common for others to engage in business practices that are prohibited by our internal policies and procedures or United States regulations applicable to us. Although we have implemented policies and procedures designed to ensure compliance with these laws and policies, there can be no assurance that all of our employees, contractors, channel partners and agents will comply with these laws and policies. Should it be determined that any of our foreign subsidiaries or its employees have violated applicable law, it could be subject to legal penalties and its and our business reputation could be damaged.

If our efforts in acquiring and integrating other companies or product lines or establishing joint ventures fail, our business may not grow.

As part of our growth strategy, we intend to continue pursuing acquisitions of complementary businesses or products and creating joint ventures. Our ability to continue to grow in this manner depends upon our ability to identify, negotiate and finance suitable acquisitions or joint venture arrangements. In addition, acquisitions and their subsequent integration involve a number of risks, including, but not limited to:

•

inaccurate assessments of disclosed liabilities and the potentially adverse effects of undisclosed liabilities;

•

unforeseen difficulties in assimilating acquired companies, their products, and their culture into our existing business;

•

unforeseen delays in realizing the benefits from acquired companies or product lines, including projected efficiencies, cost savings, revenue synergies and profit margins;

•

unforeseen diversion of our management’s time and attention from other business matters;

•

unforeseen difficulties resulting from insufficient prior experience in any new markets we may enter;

•

unforeseen difficulties in retaining key employees and customers of acquired businesses; and

•

increases in our indebtedness and contingent liabilities, which could in turn restrict our ability to raise additional capital when needed or to pursue other important elements of our business strategy.

Execution of our acquisition strategy with respect to some companies or product lines could fail or could result in unanticipated costs to us that were not apparent despite our due diligence efforts, either of which could hinder our growth or adversely impact our results of operations.

Each of our credit facilities and indentures contain restrictions on certain mergers and asset dispositions.

We derive a significant amount of our revenues from foreign markets, which subjects us to additional business risks that could adversely affect our results of operations.

Our foreign manufacturing operations accounted for approximately 38% of our net trade sales for the fiscal year ended May 31, 2015, not including exports directly from the U.S. which accounted for approximately 2% of our net trade sales for fiscal 2015. We plan to continue to grow our international operations and the growth and maintenance of such operations could be adversely affected by changes in political and economic conditions, inflation rates, trade protection measures, restrictions on foreign investments and repatriation of earnings, changing intellectual property rights, difficulties in staffing and managing foreign operations and changes in regulatory requirements that restrict the sales of our products or increase our costs. Also, changes in exchange rates between the U.S. dollar and other currencies could potentially result in material volatility in our costs and earnings and may also adversely affect the carrying values of our assets located outside the U.S.

We could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and similar anti-bribery laws of other countries, as well as trade sanctions administered by the office of Foreign Assets Control and the Department of Commerce.

The U.S. Foreign Corrupt Practices Act (“FCPA”) and similar anti-bribery laws of other countries generally prohibit companies and their intermediaries from making improper payments to governmental officials or others for the purpose of obtaining or retaining business or for other unfair advantage. Our policies mandate compliance with these anti-bribery laws. We operate in many parts of the world that have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. Although we have internal controls and procedures designed to ensure compliance with these laws, there can be no assurance that our controls and procedures will prevent a violation of these laws.

We are required to comply with U.S. regulations on trade sanctions and embargoes administered by the U.S. Department of the Treasury, Office of Foreign Assets Control (“OFAC”), the Commerce Department and similar multi-national bodies and governmental agencies worldwide, which are complex and constantly changing. A violation thereof could subject us to regulatory enforcement actions and significant civil and criminal penalties and fines.

Violations of these laws, or allegations of such violations, could disrupt our business and result in a material adverse effect on our results of operations, financial condition, and cash flows.

Our operations are subject to the effect of global tax law changes, some of which have been, and may be in the future, retroactive in application.

Our operations are subject to various federal, state, local and foreign tax laws and regulations which govern, among other things, taxes on worldwide income. Any potential tax law changes may, for example, increase applicable tax rates, have retroactive application, or impose stricter compliance requirements in the jurisdictions in which we operate, which could reduce our consolidated net earnings.

In response to, for instance, an economic crisis or recession, governments may revise tax laws, regulations or official interpretations in ways that could have a significant impact on us, including modifications that could, for example, reduce the profits that we can effectively realize from our non-U.S. operations, or that could require costly changes to those operations, or the way in which they are structured. If changes in tax laws, regulations or interpretations were to significantly increase the tax rates on non-U.S. income, our effective tax rate could increase, our profits could be reduced, and if such increases were a result of our status as a U.S. company, could place us at a disadvantage to our non-U.S. competitors if those competitors remain subject to lower local tax rates.

Further, legislative and regulatory action may be taken in the U.S. which, if ultimately enacted, could subject us to increased taxes which could adversely affect our effective tax rate.

We cannot predict the outcome or timing of any specific legislative, regulatory or other tax proposals or changes.

We could be adversely affected by failure to comply with federal, state and local government procurement regulations and requirements.

We have contracts with federal, state and local governmental entities, and are required to comply with specific procurement regulations and other requirements relating to those contracts. We also enter into subcontracts with other federal, state, or local prime contractors. Further, we may serve as a supplier to an entity that is a federal, state, or local prime or subcontractor. Requirements in our contracts and those requirements flowed down to us in our capacity as a subcontractor or supplier, although customary in government contracts, may impact our performance and compliance costs. Failure to comply with these regulations and requirements or to make required disclosures under contract could result in reductions of the value of contracts, contract modifications or termination for cause, adverse past performance ratings, actions under a federal or state false claims statute, suspension or debarment from government contracting or subcontracting for a period of time and the assessment of penalties and fines, any of which could negatively impact our results of operations and financial condition and could have a negative impact on our reputation and ability to procure other government contracts in the future.

Terrorist activities and other acts of violence or war, natural disasters and other disruptions have negatively impacted in the past and could negatively impact in the future the U.S. and foreign countries, the financial markets, the industries in which we compete, our operations and profitability.

Terrorist activities and natural disasters have contributed to economic instability in the U.S. and elsewhere, and further acts of terrorism, violence, war or natural disasters could affect the industries in which we compete, our ability to purchase raw materials, our results of operations and financial condition. In addition, terrorist activities and natural disasters may directly impact our physical facilities or those of our suppliers or customers, which could impact our sales, our production capability and our ability to deliver products to our customers. Disruptions could also occur due to cyber-attacks, computer or equipment malfunction (accidental or intentional), operator error or process failures. Any disruption of our ability to produce or distribute our products could result in a material decrease in our revenues or significant additional costs to replace, repair or insure our assets, which could have a material adverse impact on our financial condition and results of operations.

Data privacy and data security considerations could impact the Company’s business.

The interpretation and application of data protection laws in the U.S., Europe and elsewhere are uncertain and evolving. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our data practices. Complying with these various laws is difficult and could cause us to incur substantial costs or require us to change our business practices in a manner adverse to our business.

Despite our efforts to protect sensitive information and confidential and personal data and comply with and implement data security measures, our facilities, and systems may be vulnerable to security breaches and other data loss, including cyber-attacks and, in fact, we have experienced data security incidents that have not had a material impact on our financial results. In addition, it is not possible to predict the impact of the future loss,

alteration or misappropriation of information in our possession related to us, our employees, former employees, customers or suppliers. This could lead to negative publicity, legal claims, theft, modification or destruction of proprietary information or key information, damage to or inaccessibility of critical systems, manufacture of defective products, production downtimes, operational disruptions and other significant costs, which could adversely affect our reputation, financial condition and results of operations.

Although we have insurance, it may not cover every potential risk associated with our operations.

Although we maintain insurance of various types to cover many of the risks and hazards that apply to our operations, our insurance may not cover every potential risk associated with our operations. The occurrence of a significant adverse event, the risks of which are not fully covered by insurance, could have a material adverse effect on our financial condition and results of operations. Moreover, no assurance can be given that we will be able to maintain adequate insurance in the future at rates we consider reasonable.

Adverse weather conditions may reduce the demand for some of our products and could have a negative effect on our sales.

From time to time, adverse weather conditions in certain parts of the U.S. and other countries in which we do business have had an adverse effect on our sales of paint, coatings, roofing, construction products and related products. For example, unusually cold and rainy weather, especially during the general construction and exterior painting season, could have an adverse effect on sales of such products. As a result, we have historically experienced weaker sales and net income in our third fiscal quarter (December through February) in comparison to our performance during our other fiscal quarters.

Not Applicable.

Item 2. Properties.

Our corporate headquarters and a plant and offices for one subsidiary are located on a 119-acre site, which we own in Medina, Ohio. As of May 31, 2015, our operations occupied a total of approximately 14.2 million square feet, with the majority, approximately 11.8 million square feet, devoted to manufacturing, assembly and storage.

We lease certain of our properties under long-term leases. Some of these leases provide for increased rent based on an increase in the cost-of-living index. For information concerning our rental obligations, see Note L, “Leases” of the Notes to Consolidated Financial Statements, which appears in the 2015 Annual Report to Stockholders and is incorporated herein by reference. Under many of our leases, we are obligated to pay certain varying insurance costs, utilities, real property taxes and other costs and expenses.

We believe that our manufacturing plants and office facilities are well maintained and suitable for our operations.

Item 3. Legal Proceedings.

Asbestos Litigation and the Bankruptcy Filings by SPHC and Bondex

On May 31, 2010, Bondex and its parent, SPHC, filed voluntary petitions in the United States Bankruptcy Court for the District of Delaware to reorganize under chapter 11 of the U.S. Bankruptcy Code. SPHC is the parent company of Bondex and also serves as the parent company for various operating companies that are not part of the reorganization filing, including Chemical Specialties Manufacturing Corp., Day-Glo Color Corp., Dryvit Systems, Inc. through Dryvit Holdings, Inc., Guardian Protection Products Inc., Kop-Coat Inc., TCI, Inc. and RPM Wood Finishes Group, Inc. The Bankruptcy Plan was confirmed on December 10, 2014 and, effective as of December 23, 2014, Bondex, SPHC, Republic and NMBFiL emerged from bankruptcy. For information regarding asbestos litigation involving SPHC and Bondex, see Note A(2) to the Consolidated Financial Statements.

Environmental Proceedings

As previously reported, several of our subsidiaries are, from time to time, identified as a “potentially responsible party” under the federal Comprehensive Environmental Response, Compensation and Liability Act and similar local environmental statutes. In some cases, our subsidiaries are participating in the cost of certain clean-up efforts or other remedial actions. Our share of such costs to date, however, has not been material and management believes that these environmental proceedings will not have a material adverse effect on our consolidated financial condition or results of operations. See “Item 1 — Business — Environmental Matters,” in this Annual Report on Form 10-K.

Item 4. Mine Safety Disclosures.

Not applicable.
