PART I

ITEM 1. BUSINESS

Company Overview

We manufacture, formulate and globally distribute specialty chemicals. We grow primarily by purchasing product lines and businesses that operate in segments of the specialty chemical industry that:

• provide an opportunity to obtain a significant share of the market segment through further acquisitions and organic growth;

• are of a size that larger industry participants generally find too small to be attractive;

• have niche products with well established and proven commercial uses;

• offer products that have moved well beyond their discovery phase and require little or no on-going research and development expenditures; and

• have significant barriers to entry.

We have acquired and currently operate businesses selling electronic chemicals and industrial wood treating chemicals. Our electronic chemicals segment provides high purity and ultra purity, wet process chemicals to the semiconductor industry, primarily to clean and etch silicon wafers in the production of semiconductors. We are the leading supplier of these wet process chemicals to the semiconductor industry in the United States, have a significant presence in Europe and an increasing presence in Asia. Our wood treating chemicals, pentachlorophenol, or penta, and creosote, are sold to industrial customers who use these preservatives primarily to extend the useful life of wood utility poles and railroad crossties. We are the only supplier of penta in North America, and we are the principal supplier of creosote in the United States to wood treaters who do not produce their own creosote.

For the twelve months ended July 31, 2013, we generated revenues of $263.3 million and net income of $9.3 million. On July 31, 2013, we had total long-term debt, net of current maturities, of $85.0 million, cash and cash equivalents of $13.9 million and total stockholders’ equity of $117.2 million.

Business Strategy

We seek to build long-term shareholder value through smart and efficient management of our existing operations, and through the rapid integration and optimization of acquired businesses. We favor businesses with stable markets, harvesting operational synergies and enhancing margins by bringing a focus to mature, specialty chemicals that large companies often ignore. Our actions are guided by our core values, which emphasize safety first, reliability to our customers, strength of character, respect for others and good stewardship of company assets. Three fundamental core strengths enable the successful execution of our strategy:

• Operate. We seek to maximize cash flow by managing right-sized plants with the best-available technology. We enhance the value of our operations through our continual improvement program, which concentrates on customer satisfaction and efficient management of our resources to increase our profitability and cash flow.

• Acquire. The cash flow generated by the businesses that we operate provides us with the ability to pursue further acquisitions in order to build on one of our existing segments, or to establish a new business platform for future growth. We employ a methodical approach to identify and evaluate potential acquisitions, only pursuing those that meet our financial and strategic criteria. Our discipline throughout the acquisition process maximizes the chances of long-term success.

• Integrate. We have consistently improved our ability as an organization to integrate progressively larger and more complex acquisitions. Our focus is to maintain reliable service to our customers during the integration period, identify and harvest the long-term synergies, and efficiently absorb acquired businesses into our operations. An effective integration strategy is an essential precondition for our operational success.

Business Segments

Electronic Chemicals. Our electronic chemicals business sells high purity and ultra purity wet process chemicals primarily to the semiconductor industry. These chemicals are used to clean and etch silicon wafers in the production of semiconductors. The business was acquired in December 2007 from Air Products and Chemicals, Inc. (“Air Products”), and expanded with our purchases in May 2013 and in March 2010 of the electronic chemicals businesses of OM Group, Inc. (“OM Group”) and General Chemical Performance Products LLP (“General Chemical”), respectively. Our products include sulfuric, phosphoric, nitric and hydrofluoric acids, ammonium hydroxide, hydrogen peroxide, isopropyl alcohol, other specialty organic solvents and various blends of chemicals. Our customers rely on us to provide products with very low levels of contaminants and particles, in some cases at less than 100 parts per trillion levels. We purchase the needed chemicals from various suppliers, and in some cases we purify those chemicals further. We are responsible for product purity levels, for analytical testing, blending and packaging, and for distribution to our customers. Our products are sold in bulk and in containers, including bottles, drums and totes. This process is largely accomplished at our facilities in the Unites States, Europe and in Singapore, although we currently contract with General Chemical to produce certain products for us at its facility in California. With the purchase of the electronic chemicals business from OM Group, we now manage the chemicals usage of semiconductor customers at their sites in Singapore, a service known as Total Chemical Management (“TCM”). Our electronic chemicals business accounted for 63.0% of our net sales in fiscal year 2013, 58.5% in fiscal year 2012, and 59.3% in fiscal year 2011.

1

Wood Treating Chemicals. We supply penta and creosote to industrial customers who use these products to extend the useful life of wood, primarily utility poles and railroad crossties. Our penta products include solid blocks and concentrated solutions. Penta is used primarily to treat utility poles, protecting them from insect damage and decay. We estimate that approximately two million treated utility poles are purchased each year by electric utility companies in the United States and that approximately 45% are treated with penta. We manufacture solid penta blocks at our facility in Matamoros, Mexico. We sell solid penta to our customers, or dissolve it to make concentrated solutions of penta at our Matamoros, Mexico and Tuscaloosa, Alabama facilities. We sell penta products in the United States and in Canada. The hydrochloric acid we produce as a byproduct of penta production is primarily sold in Mexico for use in the steel and oil well service industries. Creosote is a wood preservative used to treat utility poles and railroad crossties. Creosote is produced by the distillation of coal tar, a by-product of the transformation of coal into coke. In the last five years, production of wood crossties in North America has averaged 21.0 million ties annually. Almost all wood crossties are treated with creosote. We believe that about 10% of utility poles are treated with creosote annually. We sell creosote to wood treaters throughout the United States. Our wood treating chemicals constituted about 37.0% of our net sales in fiscal year 2013, 41.4% in fiscal year 2012 and 40.7% in fiscal year 2011.

Suppliers

In electronic chemicals we rely on a variety of suppliers for our raw materials, some of which we purchase on open account and others which we purchase under supply contracts. The number of suppliers is often limited, particularly as to the specific grade of raw material required by us to supply high purity and ultra purity products to our customers. In particular, General Chemical operates their Bay Point, California facility under a manufacturing agreement with us to produce our principal source for hydrofluoric acid in North America. No assurance can be given that the loss of a supplier would not have a material adverse effect on our financial position or results of operations.

In our wood treating chemical segments, we depend on outside suppliers for all of the raw materials needed to produce our penta products, and are subject to fluctuations in the price of those materials. The principal raw materials used for our penta products are chlorine, phenol and co-solvent, each of which we purchase from a limited number of suppliers. We purchase almost all of the creosote we sell from two suppliers, Rütgers and Koppers. Our creosote supply agreements with each of them provide that we purchase an agreed minimum volume of creosote in each calendar year at a fluctuating, mutually agreed or formula-based price.

Customers

We sell our products to approximately 550 customers. One of our electronic chemicals customers, Intel Corporation, accounted for 10% or more of our revenues in fiscal years 2013, 2012 and 2011. In addition, one of our wood treating chemicals customers, Stella Jones Corporation, accounted for 10% or more of our revenues in fiscal years 2013, 2012 and 2011. No other customer accounted for 10% or more of our revenue in fiscal years 2013, 2012 and 2011. The loss of Intel or Stella Jones would have a material adverse effect on sales of our electronic chemicals and wood treating chemicals businesses, respectively. Assuming that the level of overall demand for wood treating chemicals remained the same, we do not believe that the loss of any other customer in that segment would have a material adverse effect on sales of our wood treating chemicals.

Marketing

We sell to our electronic chemicals customers through a combination of strategic account managers and other sales personnel organized by geographic region. Our wood treating chemicals are sold in the United States through an internal sales force.

Geographical Information

Sales made to customers in the United States were 76.0% of total revenues in fiscal year 2013, 84.0% in 2012 and 85.7% in 2011. Sales made outside of the United States were primarily electronic chemicals sold in Europe, Israel and Singapore. As of the end of fiscal year 2013, our property, plant and equipment were allocated, based on net book value, 53.5% in the United States and 46.5% elsewhere.

Competition

There are only a few firms competing with us in the sale of our products. We compete by selling our products at competitive prices and maintaining a strong commitment to product quality and customer service.

2

In electronic chemicals in North America, we believe that we have the largest market share, and our principal competitors include Honeywell, Kanto Corporation and Avantor (formerly Mallinckrodt Baker). Internationally, we compete in Europe primarily with BASF, Technic and Honeywell, and in Asia with BASF, Kanto Corporation and others. We believe our market share in Europe is comparable to our competitors, and we do not participate materially in the market in Asia outside of Singapore.

In our electronic chemicals business, our customers demand that each of their suppliers and each product used to make their semiconductors go through a rigorous qualification process. Once a customer has qualified one or more suppliers and their products for one of its fabrication facilities, there is often substantial reluctance to switch to other suppliers.

The principal wood preserving chemicals for industrial users are penta, creosote and chromated copper arsenate, or CCA. We supply United States industrial users with both penta and creosote, but not CCA. We are the only manufacturer of penta in North America. Penta is used primarily to treat electric, telephone and other utility poles, to protect them from insect damage and decay. We estimate that approximately two million treated utility poles are purchased each year by utility companies in the United States. Of that amount, we estimate approximately 45% are treated with penta and that about 10% are treated with creosote. The remaining poles are treated primarily with CCA. We provide the wood treating industry in the United States with most of its annual consumption of creosote not produced for internal use by Koppers and other creosote distillers.

Our wood treating chemicals must be registered prior to sale under United States law. See “Environmental and Safety Matters—Licenses, Permits and Product Registrations.” As a condition to registration, any company wishing to manufacture and sell these products must provide substantial scientific research and testing data regarding the chemistry and toxicology of the products to the U.S. Environmental Protection Agency (“EPA”). This data must be generated by the applicant, or the applicant must purchase access to the information from other data providers. We believe that the cost of satisfying the data submission requirement serves as an impediment to the entry of new competitors, particularly those with lesser financial resources. While we have no reason to believe that the product registration requirement will be materially modified, we cannot give any assurances as to the effect of such a discontinuation or modification on our competitive position.

Employees

As of the end of fiscal year 2013, we had a total of 740 full-time employees. We employed 643 employees in our electronic chemicals segment, 63 employees in wood treating and 34 employees in administration and corporate. Approximately 17.0% of our employees are represented by labor unions, workers councils or comparable organization, particularly in Mexico and Europe.

Environmental and Safety Matters

Our operations are subject to extensive federal, state and local laws, regulations and ordinances in the United States and abroad relating to the protection of the environment and human health and to safety, including those pertaining to chemical manufacture and distribution, waste generation, storage and disposal, discharges to waterways, and air emissions and various other health and safety matters. Governmental authorities have the power to enforce compliance with their regulations, and violators may be subject to civil, criminal and administrative penalties, injunctions or both. We devote significant financial resources to ensure compliance, and we believe that we are in substantial compliance with all the applicable laws and regulations.

We anticipate that the regulation of our business operations under federal, state and local environmental laws in the United States and abroad will increase and become more stringent over time. We cannot estimate the impact of increased and more stringent regulation on our operations, future capital expenditure requirements or the cost of compliance.

United States Regulation. Statutory programs relating to protection of the environment and human health and to safety in the United States include, among others, the following.

CERCLA. The Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, also known as “CERCLA” and “Superfund”, and comparable state laws generally impose joint and several liability for costs of investigation and remediation and for natural resource damages, without regard to fault or the legality of the original conduct, on certain classes of persons with respect to the release into the environment of specified substances, including under CERCLA those designated as “hazardous substances.” These persons include the present and certain former owners or operators of the site where the release occurred and those that disposed or arranged for the disposal of the hazardous substance at the site. These liabilities can arise in association with the properties where operations were conducted, as well as disposal facilities where wastes were sent. Many states have adopted comparable or more stringent state statutes. In the course of our operations, we generated materials that fall within CERCLA’s definition of hazardous substances. We may be the owner or operator of sites on which hazardous substances have been released and may have generated hazardous substances that have been transported to or otherwise released upon offsite facilities. We may be responsible under CERCLA for all or part of the costs to clean up facilities at which such substances have been released by previous owners or operators and offsite facilities to which our wastes were transported and for associated damages to natural resources.

3

Resource Conservation and Recovery Act. The federal Resource Conservation and Recovery Act, as amended (“RCRA”) and comparable state laws regulate the treatment, storage, disposal, remediation and transportation of wastes, specifically under RCRA those designated as “hazardous wastes.” The EPA and various state agencies have limited the disposal options for these wastes and impose numerous regulations upon the treatment, storage, disposal, remediation and transportation of them. Our operations generate wastes that are subject to RCRA and comparable state statutes. Furthermore, wastes generated by our operations that are currently exempt from treatment as hazardous wastes may be designated in the future as hazardous wastes under RCRA or other applicable statutes and, therefore, may be subject to more rigorous and costly treatment, storage and disposal requirements. Governmental agencies (and in the case of civil suits, private parties in certain circumstances) can bring actions for failure to comply with RCRA requirements, seeking administrative, civil, or criminal penalties and injunctive relief, to compel us to abate a solid or hazardous waste situation that presents an imminent or substantial endangerment to health or the environment.

Clean Water Act. The federal Clean Water Act imposes restrictions and strict controls regarding the discharge of wastes and fill materials into waters of the United States. Under the Clean Water Act, and comparable state laws, the government (and in the case of civil suits, private parties in certain circumstances) can bring actions for failure to comply with Clean Water Act requirements and enforce compliance through civil, criminal and administrative penalties for unauthorized discharges of hazardous substances and of other pollutants. In the event of an unauthorized discharge of wastes, we may be liable for penalties and subject to injunctive relief.

Clean Air Act. The federal Clean Air Act (CAA), as amended, and comparable state and local laws restrict the emission of air pollutants from many sources and also impose various monitoring and reporting requirements. These laws may require us to obtain pre-approval for the construction or modification of certain projects or facilities expected to produce or significantly increase air emissions, obtain and strictly comply with air permit requirements or utilize specific equipment or technologies to control emissions. Governmental agencies (and in the case of civil suits, private parties in certain circumstances) can bring actions for failure to strictly comply with air pollution regulations or permits and generally enforce compliance through administrative, civil or criminal enforcement actions, resulting in fines, injunctive relief (which could include requiring us to forego construction, modification or operation of sources of air pollutants) and imprisonment. While we may be required to incur certain capital expenditures for air pollution control equipment or other air emissions-related issues, we do not believe that such requirements will have a material adverse effect on our operations.

Greenhouse Gas Regulation. More stringent laws and regulations relating to climate change and greenhouse gases (GHGs) may be adopted in the future and could cause us to incur material expenses in complying with them. The EPA has begun to regulate GHGs as pollutants under the CAA. By adopting rules regulating GHG emissions from motor vehicles, the EPA triggered requirements to permit GHG emissions from stationary sources under the Prevention of Significant Deterioration (PSD) and Title V permitting programs. The EPA has implemented the so-called “Tailoring Rule” requiring that only the larger sources of GHGs obtain permits for GHG emissions. EPA’s GHGs regulations, including the Tailoring Rule, are being challenged in court; we cannot predict the outcome of those challenges. There is still the possibility that federal legislation will be adopted to change the GHG permitting program put in place by the EPA, but to date, efforts at a comprehensive GHG legislative package (such as a cap and trade program) appear not to be moving forward in Congress. We may incur significant costs to control our emissions and comply with regulatory requirements associated with GHG permitting.

In addition to federal regulation, a number of states, individually and regionally, and localities also are considering implementing or have implemented GHG regulatory programs. These regional and state initiatives may result in so–called cap–and–trade programs, under which overall GHG emissions are limited and GHG emission “allowances” are then allocated and sold to and between persons subject to the program. These and possibly other regulatory requirements could result in our incurring material expenses to comply, e.g., by being required to purchase or to surrender allowances for GHGs resulting from our operations or otherwise being required to control or reduce emissions. It should be noted that some scientists have concluded that increasing concentrations of GHGs in the Earth’s atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts, and floods and other climatic events; if any such effects were to occur, they could have an adverse effect on our assets and operations in locations vulnerable to such events.

Occupational Safety. Our operations are also governed by laws and regulations relating to workplace safety and worker health, principally the Occupational Safety and Health Act (OSHA) and its regulations. The OSHA hazard communication standard, the EPA’s community right-to-know regulations and similar state programs may require us to organize and/or disclose information about hazardous materials used or produced in our operations. We believe that we are in substantial compliance with these applicable requirements.

Foreign Regulation. We are subject to various laws, regulations and ordinances to protect the environment, human health and safety promulgated by the governmental authorities in Mexico, Europe, Singapore, and in other countries where we do business. Each country has laws and regulations concerning waste treatment, storage and disposal, discharges to waterways, air emissions and workplace safety and worker health. Their respective regulatory authorities are given broad authority to enforce compliance with environmental, health and safety laws and regulations, and can require that operations be suspended pending completion of required remedial action.

4

Licenses, Permits and Product Registrations. Certain licenses, permits and product registrations are required for our products and operations in the United States, Mexico, Europe, Singapore, and in other countries where we do business. The licenses, permits and product registrations are subject to revocation, modification and renewal by governmental authorities. In the United States in particular, producers and distributors of chemicals such as penta and creosote are subject to registration and notification requirements under federal law (including under the Federal Insecticide, Fungicide and Rodenticide Act (“FIFRA”) and the Toxic Substances Control Act, and comparable state law) in order to sell those products in the United States. Compliance with these laws has had, and in the future will continue to have, a material effect on our business, financial condition and results of operations. Under FIFRA, the law’s registration system requires an ongoing submission to the EPA of substantial scientific research and testing data regarding the chemistry and toxicology of pesticide products by manufacturers.

ITEM 1A. RISK FACTORS

You should carefully consider the risks described below, together with all of the other information included in this report. We believe the risks and uncertainties described below are the most significant we face. The occurrence of any of the following risks could materially harm our business, financial condition or results of operations. In that case, the trading price of our common stock could decline, and you may lose all or part of your investment.

Risks Relating to Our Business

The industries in which we operate are competitive. This competition may prevent us from raising prices at the same pace as our costs increase, making it difficult for us to maintain existing business and win new business.

We operate in competitive markets. Certain of our competitors have substantially greater financial and technical resources than we do. Additionally, new competitors may enter our markets. We may be required to reduce prices if our competitors reduce prices, or as a result of any other downward pressure on prices for our products and services, which could have an adverse effect on us. In electronic chemicals particularly, we compete with several very large, international companies. Our customers have regularly requested price decreases and maintaining or raising prices has been difficult over the past several years and will likely continue to be so in the near future. Competition in electronic chemicals is based on a number of factors, including price, freight economics, product quality and technical support. If we are unable to compete successfully, our financial condition and results of operations could be adversely affected.

We may experience a reduced demand for our wood treating chemicals, if the recent trend toward reducing creosote content in railroad crossties with a borate treatment continues, or if the demand for the wood products on which our chemicals are used decreases, and our business, results of operations, cash flow and financial condition may be adversely affected.

Our wood treating chemicals, penta and creosote, are sold into mature markets. The principal consumers of our wood treating chemicals are industrial wood treating companies who use our products to protect railroad crossties and wood utility poles from insect damage and decay. Recently, railroads have begun specifying that wooden crossties be treated with a borate solution in addition to being treated with creosote. This has the effect of reducing the amount of creosote used per railroad crosstie. We believe that practice will continue, and even expand in the near term. Any such expansion will adversely affect the volume of creosote that we sell and may have a material adverse effect on our business, financial condition and results of operations. In addition, our wood treating products are sold into relatively stable markets. Demand for treated wood generally increases or decreases with the financial strength and maintenance budgets of railroads and electric utilities, and demand can vary with damage levels suffered from severe storms. A significant decline in either wood crosstie or utility pole sales could have a material adverse effect on our business, financial condition and results of operations.

5

The industries that we compete in are subject to economic downturns.

An economic downturn in the electronic industry as a whole or other events (e.g., labor disruptions) resulting in significantly reduced production at the manufacturing plants of our customers, could have a material adverse impact on the results of our electronic chemicals segment. Similarly, an economic downturn affecting utilities or major railroads could have a material adverse effect on demand for our wood treating chemicals.

A significant portion of our revenue and operating income are concentrated in a small number of customers.

We derive a significant portion of our revenues and operating income in our electronic chemicals and wood treating segments from sales of products to a small number of customers. As a result, the loss of Intel, Stella or another significant customer, or a material reduction of demand from any of those customers, could adversely affect our revenues and operating income.

We will continue to pursue new acquisitions or joint ventures, and any such transaction could result in operating or management problems that adversely affect operating results. We remain subject to the ongoing risks of successfully integrating and managing the acquisitions and joint ventures that are completed. In particular, we are now in the process of integrating our latest electronic chemicals business acquisition from OM Group, and no assurance can be given that the integration will achieve successfully all or most of the advantages sought in the acquisition.

The acquisitions we make expose us to the risk of integrating that acquisition. An integration effort impacts various areas of our business, including our management, production facilities, information systems, accounting and financial reporting, and customer service. Disruption to any of these areas could materially harm our financial condition or results of operations.

In our electronic chemicals segment, we are now in the process of integrating the UPC subsidiaries acquired from OM Group at the end of May 2013. The size and complexity of that effort is substantial, particularly because of the number of facilities involved, the broad geography of the electronic chemicals footprint, and the detailed coordination required to meet the needs of our customers. We believe that a successful integration will allow us to achieve important advantages for our business and financial results, particularly from product sourcing and supply chain optimization. We currently anticipate that this integration effort will be completed in fiscal year 2015, and will begin to generate a substantial improvement in segment operating income. No assurance can be given, however, that the effort will not take longer or be more costly than currently believed, and no assurance can be given that all or most of the advantages sought in the integration will be obtained.

We expect to continue to pursue new acquisitions or joint ventures, a pursuit which could consume substantial time and resources. The successful implementation of our operating strategy in current and future acquisitions and joint ventures may require substantial attention from our management team, which could divert management attention from existing businesses. The businesses acquired, or the joint ventures entered into, may not generate the cash flow and earnings, or yield the other benefits anticipated at the time of their acquisition or formation. The risks inherent in any such strategy could have an adverse impact on our results of operation or financial condition.

If pentachlorophenol is listed as a Persistent Organic Pollutant by under the Stockholm Convention, our ability to manufacture or sell our penta products may be adversely affected.

In October 2012, the United Nations Persistent Organic Pollutant Review Committee recommended continuing the process to consider classifying penta as a persistent organic pollutant (“POP”), and in October 2013 the committee confirmed that decision and concluded that the nature of penta and the chemicals to which it degrades satisfy the definition of a POP. The POP Review Committee comprises representatives from countries that have ratified the treaty known as the Stockholm Convention, which include Canada and Mexico but not the United States. The recent determination is the latest step toward classifying penta as a POP, and restricting or prohibiting uses of penta in countries that have approved the treaty. The full Conference of the Parties of the Stockholm Convention must approve the listing, and if approved, a decision must be made on whether to merely restrict the uses of penta or prohibit its use entirely. The next meeting of the POP Review Committee will be in late 2014, and will consider the impact of economic and social aspects on any decision respecting penta. If the committee reaches a conclusion at that time, its decision will then be submitted to the Conference of the Parties for consideration, perhaps in 2015. We will incur substantial expenses for testing and other regulatory costs to participate and respond to this process. Although the United States is not bound by the determination of the Conference of the Parties, because it did not adopt the Stockholm Convention treaty, Canada and Mexico are governed by treaty. Although the POP review is a multi-year process, no assurance can be given that the ultimate action of the Conference of the Parties will not have a material adverse affect on our financial condition and results of operation.

6

We are dependent on a limited number of suppliers for certain key raw materials, the loss of any one of which could have a material adverse effect on our financial condition and results of operations.

We depend on a limited number of suppliers for certain key raw materials needed by our businesses, such as sulfuric, hydrofluoric and nitric acids and creosote. Those suppliers are subject to a variety of operational and commercial constraints that can adversely impact our supply. If we were to lose suppliers for key raw materials, we might have difficulty securing a replacement supplier at reasonable cost, and no assurance can be given that such loss would not have a material adverse effect on our financial condition and results of operations. Our creosote supply agreement with our European supplier expires December 31, 2013. Although we are negotiating to extend that agreement, no assurance can be given that the effort will be successful, or if successful, that the new agreement will not contain price or other terms and conditions that are unfavorable and adversely affect our financial condition or results of operations.

The implementation of a new enterprise resource planning system could cause a financial statement error not to be detected, and could take longer and be more costly than anticipated.

We are in the process of implementing a new enterprise resource planning (“ERP”) system to replace our current system. This is a complex process, and the new system will result in changes to our internal controls over financial reporting, including disclosure controls and procedures. The possibility exists that the migration to new ERP system could adversely affect the effectiveness of our internal controls over financial reporting. Furthermore, no assurance can be given that the effort will not take longer or be more costly than currently believed.

If we are unable to identify, fund and execute new acquisitions, we will not be able to execute a key element of our business strategy.

Our strategy is to grow primarily by acquiring additional businesses and product lines. We cannot assure you that we will be able to identify, acquire or profitably manage additional businesses and product lines, or successfully integrate any acquired business or product line without substantial expenses, delays or other operational or financial difficulties. Financing for acquisitions may not be available, or may be available only at a cost or on terms and conditions that are unacceptable to us. Further, acquisitions may involve a number of special risks or effects, including diversion of management’s attention, failure to retain key acquired personnel, unanticipated events or circumstances, legal liabilities, impairment of acquired intangible assets and other one-time or ongoing acquisition-related expenses. Some or all of these special risks or effects could have a material adverse effect on our financial and operating results. In addition, we cannot assure you that acquired businesses or product lines, if any, will achieve anticipated revenues and earnings.

The consideration we pay in connection with an acquisition also may affect our financial results. If we were to proceed with one or more significant acquisitions in which the consideration included cash, we could be required to use a substantial portion of our available cash or obtain debt or equity financing. To the extent that we issue shares of our capital stock or other rights to purchase shares of our common stock as consideration for an acquisition or in connection with the financing of an acquisition, including options or other rights, our existing common shareholders may be diluted, and our earnings per share may decrease.

We may experience increased costs and production delays if suppliers fail to deliver materials or if prices increase for raw materials and other goods and services that we purchase from third parties.

We purchase raw materials for our electronic chemicals business from a number of domestic and foreign suppliers. Although we believe that the raw materials we require in our electronic chemicals business will be available in sufficient supply on a competitive basis for the foreseeable future, continued increases in the cost of raw materials, including energy and other inputs used to make our products, could affect future sales volumes, prices and margins for our products. If a supplier should cease to deliver goods or services to us, we would in most cases find other sources. However, such a disruption could result in added cost and manufacturing delays. In addition, political instability, war, terrorism and other disruptions to international transit routes could adversely impact our ability to obtain key raw materials in a timely fashion, or at all.

Increases in the price of our primary raw materials may decrease our profitability and adversely affect our liquidity, cash flow, financial condition and results of operations.

The prices we pay for raw materials in our businesses have increased significantly in the last several years, and we have not always been able to pass those increases through to our customers fully and timely. In the future, we may be unable to pass on increases in our raw material costs, and raw material price increases may erode the profitability of our products by reducing our gross profit. Price increases for raw materials may also increase our working capital needs, which could adversely affect our liquidity and cash flow. For these reasons, we cannot assure you that raw material cost increases in our businesses would not have a material adverse effect on our financial condition and results of operations.

Our ability to make payments on our debt will be contingent on our future operating performance, which will depend on a number of factors that are outside of our control.

Our ability to make principal and interest payments on our debt is contingent on our future operating performance, which will depend on a number of factors, many of which are outside of our control. The degree to which we are leveraged could have other important negative consequences, including the following:

• we must dedicate a substantial portion of our cash flows from operations to the payment of our indebtedness, reducing the funds available for future working capital requirements, capital expenditures, acquisitions or other general corporate requirements;

• a significant portion of our borrowings are, and will continue to be, at variable rates of interest, which may result in higher interest expense in the event of increases in interest rates;

• we may be more vulnerable to a downturn in the segments in which we operate or a downturn in the economy in general;

• we may be limited in our flexibility to plan for, or react to, changes in our businesses and the segments in which we operate;

• we may be placed at a competitive disadvantage compared to our competitors that have less debt;

• we may be limited in our ability to react to unforeseen increases in certain costs and obligations arising in our businesses, including environmental liabilities;

• we may determine it to be necessary to dispose of certain assets or one or more of our businesses to reduce our debt; and

• our ability to borrow additional funds may be limited.

If we are unable to make scheduled debt payments or comply with the other provisions of our debt instruments, our lenders may be permitted under certain circumstances to accelerate the maturity of the indebtedness owed to them and exercise other remedies provided for in those instruments and under applicable law.

Restrictions in our debt agreements could limit our growth and our ability to respond to changing conditions.

Our debt agreements contain a number of significant covenants which affect our ability to take certain actions and restrict our ability to incur additional debt. These include covenants that prohibit certain acquisitions that are not approved by our lenders. In addition, our debt agreements require us to maintain certain financial ratios and satisfy certain financial condition tests, which may require us to take action to reduce our debt or take some other action to comply with them.

These restrictions could limit our ability to obtain future financings, make needed capital expenditures, withstand a future downturn in our business or the economy in general or otherwise conduct necessary corporate activities. We may also be prevented from taking advantage of business opportunities that arise because of the limitations that these restrictive covenants impose on us.

A breach of any of these covenants would result in a default under the applicable debt agreement. A default, if not waived, could result in acceleration of the debt outstanding under the agreement and in a default with respect to, and acceleration of, the debt outstanding under our other debt agreements. The accelerated debt would become immediately due and payable. If that should occur, we may not be able to pay all such debt or to borrow sufficient funds to refinance it. Even if new financing were then available, it may not be on terms that are acceptable to us.

We are subject to extensive environmental laws and regulations and may incur costs that have a material adverse effect on our financial condition as a result of violations of or liabilities under environmental laws and regulations.

Like other companies involved in environmentally sensitive businesses, our operations and properties are subject to extensive and stringent federal, state, local and foreign environmental laws and regulations, including those concerning, among other things:

• the treatment, storage and disposal of wastes;

• the investigation and remediation of contaminated soil and groundwater;

• the discharge of effluents into waterways;

• the emission of substances into the air; and

• other matters relating to environmental protection and various health and safety matters.

The EPA and other federal and state agencies, as well as comparable agencies in Mexico, Italy and in other countries where we sell our products, have the authority to promulgate regulations that could have a material adverse impact on our operations. These environmental laws and regulations may require permits for certain types of operations, require the installation of expensive pollution control equipment, place restrictions upon operations or impose substantial liability for pollution resulting from our operations. We expend substantial funds to minimize the discharge of hazardous materials in the environment and to comply with governmental regulations relating to protection of the environment. Compliance with environmental and health and safety laws and regulations has resulted in ongoing costs for us, and could restrict our ability to modify or expand our facilities or continue production, or require us to install costly pollution control equipment or incur significant expenses, including remediation costs. We have incurred, and expect to continue to incur, significant costs to comply with environmental and health and safety laws. Federal, state and foreign governmental authorities may seek fines and penalties, as well as injunctive relief, for violation of the various laws and governmental regulations, and could, among other things, impose liability on us for cleaning up the damage resulting from a release of pesticides, hazardous materials or other chemicals into the environment.

If our products are not re-registered by the EPA or are re-registered subject to new restrictions, our ability to sell our products may be curtailed or significantly limited.

Our creosote and penta product registrations are under continuous review by the EPA under FIFRA. We have submitted and will submit a wide range of scientific data to support our U.S. registrations. To satisfy the registration review, we are required to demonstrate, among other things, that our products will not cause unreasonable adverse effects on human health or the environment when used according to approved label directions. In September 2008, the EPA announced that it had determined that creosote and penta were eligible for re-registration, but the EPA proposed new restrictions on the use of those products that will require some of our customers to incur substantial additional costs and to revise certain operating procedures. The EPA also required that creosote and penta registrants provide additional research and testing data respecting certain potential risks to human health or the environment as a further condition to continued re-registration. Additionally, the cancer risk profile of penta is being reviewed under the National Toxicology Program. That review will establish a cancer risk profile that may prompt the EPA to reconsider its risk assessment, or subject penta to a greater degree of regulatory or commercial scrutiny. We cannot tell you when or if the EPA will issue a final decision concluding that the conditions of re-registration for our creosote and penta products have been satisfied, and that all additional testing requirements have been satisfied. Even though EPA concluded that our wood treating chemicals were eligible for re-registration in 2008, we cannot assure you that our products will not be subject to further data submission requirements, or be subject to use or labeling restrictions, that may have an adverse effect on our financial position and results of operations. The failure of our current or future-acquired products to be re-registered or to satisfy the registration review by the EPA, or the imposition of new use, labeling or other restrictions in connection with re-registration could have a material adverse effect on our financial condition and results of operations.

Our use of hazardous materials exposes us to potential liabilities.

Our manufacturing and distribution of chemical products involves the controlled use of hazardous materials. Our operations, therefore, are subject to various associated risks, including chemical spills, discharges or releases of toxic or hazardous substances or gases, fires, mechanical failure, storage facility leaks and similar events. Our suppliers are subject to similar risks that may adversely impact the availability of raw materials. While we adapt our manufacturing and distribution processes to the environmental control standards of regulatory authorities, we cannot completely eliminate the risk of accidental contamination or injury from hazardous or regulated materials, including injury of our employees, individuals who handle our products or goods treated with our products, or others who claim to have been exposed to our products, nor can we completely eliminate the unanticipated interruption or suspension of operations at our facilities due to such events. We may be held liable for significant damages or fines in the event of contamination or injury, and such assessed damages or fines could have a material adverse effect on our financial performance and results of operations.

The distribution and sale of our products is subject to prior governmental approvals and thereafter ongoing governmental regulation.

Our products are subject to laws administered by federal, state and foreign governments, including regulations requiring registration, approval and labeling of our products. The labeling requirements restrict the use and type of application for our products. More stringent restrictions could make our products less desirable which would adversely affect our sales and profitability. All states where our products are used also require registration before they can be marketed or used in that state.

Governmental regulatory authorities have required, and may require in the future, that certain scientific testing and data production be provided on our products. Under FIFRA, the federal government requires registrants to submit a wide range of scientific data to support U.S. registrations. This requirement significantly increases our operating expenses, and we expect those expenses will continue in the future. Because scientific analyses are constantly improving, we cannot determine with certainty whether or not new or additional tests may be required by regulatory authorities. While Good Laboratory Practice standards specify the minimum practices and procedures that must be followed in order to ensure the quality and integrity of data related to these tests submitted to the EPA, there can be no assurance that the EPA will not request certain tests or studies be repeated. In addition, more stringent legislation or requirements may be imposed in the future. We can provide no assurance that our resources will be adequate to meet the costs of regulatory compliance or that the cost of such compliance will not adversely affect our profitability.

The Registration Evaluation and Authorization of Chemicals (“REACH”) legislation may affect our ability to manufacture and sell certain products in the European Union.

REACH, which was effective on June 1, 2007, requires chemical manufacturers and importers in the European Union to prove the safety of their products. As a result, we were required to pre-register certain products and file comprehensive reports, including testing data, on each chemical substance, and perform chemical safety assessments. Additionally, substances of high concern are subject to an authorization process. Authorization may result in restrictions on certain uses of products or even prohibitions on the manufacture or importation of products. The full registration requirements of REACH will be phased in over the next ten years. We will incur additional expense to cause the registration of our products under these regulations. REACH may also affect our ability to manufacture and sell certain products in the European Union.

Our products may be rendered obsolete or less attractive by changes in industry requirements or by supply-chain driven pressures to shift to environmentally preferable alternatives.

Changes in regulatory, legislative and industry requirements, or changes driven by supply-chain pressures, may shift current customers away from products using penta, creosote or certain of our other products and toward alternative products that are believed to have fewer environmental effects. The EPA, foreign and state regulators, local governments, private environmental advocacy organizations and a number of large industrial companies have proposed or adopted policies designed to decrease the use of a variety of chemicals, including penta, creosote and others included in certain of our products. Our ability to anticipate changes in regulatory, legislative, and industry requirements, or changes driven by supply-chain pressures, will be a significant factor in our ability to remain competitive. Further, we may not be able to comply with changed or new regulatory or industrial standards that may be necessary for us to remain competitive.

We cannot assure you that the EPA, foreign and state regulators and local governments will not restrict the uses of penta, creosote or certain of our other products or ban the use of one or more of these products, or that the companies who use our products may decide to reduce significantly or cease the use of our products voluntarily. As a result, our products may become obsolete or less attractive to our customers.

Our profitability could be adversely affected by high petroleum prices.

The profitability of our business depends, to a degree, upon the price of petroleum products, both as a component of transportation costs for delivery of products to our customers and as a raw material used to make our products, including penta solutions. High petroleum prices also affect the businesses of our customers. Our penta customers dissolve our product in petroleum to make a treating solution for utility poles. Unfavorable changes in petroleum prices or in other business and economic conditions affecting our customers could reduce purchases of our products, and impose practical limits on our pricing. Any of these factors could lower our profit margins, and have a material adverse effect on our results of operations. We are unable to predict what the price of crude oil and petroleum-based products will be in the future. We may be unable to pass along to our customers the increased costs that result from higher petroleum prices.

We may be unable to identify liabilities associated with the properties and businesses that may be acquired or obtain protection from sellers against them.

The acquisition of properties and businesses requires assessment of a number of factors, including physical condition and potential environmental and other liabilities. Such assessments are inexact and inherently uncertain. The assessments made result from a due diligence review of the subject properties and businesses, but such a review may not reveal all existing or potential problems. We may not be able to obtain comprehensive contractual indemnities from the seller for liabilities that it created or that were created by any predecessor of the seller. We may be required to assume the risk of the physical or environmental condition of the properties and businesses in addition to the risk that the properties and businesses may not perform in accordance with expectations.

We are dependent upon many critical systems and processes, many of which are dependent upon hardware that is concentrated in a limited number of locations. If a catastrophe were to occur at one or more of those locations, it could have a material adverse effect on our business.

The business is dependent on certain critical systems, which support various aspects of our operations, from our computer network to our billing and customer service systems. The hardware supporting a large number of such systems is housed in a small number of locations. If one or more of these locations were to be subject to fire, natural disaster, terrorism, power loss, or other catastrophe, it could have a material adverse effect on our business. While we believe that we maintain reasonable disaster recovery programs, there can be no assurance that, despite these efforts, any disaster recovery, security and service continuity protection measures we may have or may take in the future will be sufficient.

In addition, we may be susceptible to acts of aggression on our critical operating system. “Cyber security” events such as computer viruses, electronic break-ins or other similar disruptive technological problems could also adversely affect our operations. Should such an event occur in the future, our insurance policies may not adequately compensate us for any losses that may occur due to any failures or interruptions in our computer systems and could affect our financial and operating results, causing disruptions in operations, damage of reputation, litigation, increased costs, or inaccurate information reported by our manufacturing facilities.

10

Weather may impact adversely our ability to conduct business.

Much of the creosote we sell is supplied from Europe, and we import that product through terminals in New Orleans, Louisiana and Savannah, Georgia. Our penta facility in Matamoros, Mexico, and several suppliers of raw materials for our electronic chemicals business are also located on or near the Gulf of Mexico. Thus, we are dependent on terminals and facilities located in coastal areas for a substantial portion of certain of the raw materials and creosote we use, the penta we make and for our electronic chemicals products. These terminals and facilities are vulnerable to hurricanes and other adverse weather conditions that have the potential to cause substantial damage and to interrupt operations. For example, in 2005 Hurricane Katrina closed our terminal in New Orleans, Louisiana temporarily and forced us to locate an interim substitute terminal. We cannot assure that adverse weather conditions will not affect our importation of creosote or the availability of penta and certain other raw materials in the future, the occurrence of which could have a material adverse effect on our financial condition and results of operations.

Our business success depends significantly on the reliability and sufficiency of our manufacturing facilities.

Our revenues depend significantly on the continued operation of our manufacturing facilities. The operation of our facilities involves risks, including the breakdown, failure, or substandard operation or performance of equipment, power outages, explosions, fires, earthquakes, other natural disasters, terrorism and other unscheduled downtime. The occurrence of material operational problems, the loss or shutdown of our facilities over an extended period of time due to these or other events could have a material adverse effect on our financial performance and operating results.

Our business is subject to many operational risks for which we may not be adequately insured.

We cannot assure you that we will not incur losses beyond the limits of, or outside the coverage of, our insurance policies. From time to time, various types of insurance for companies in the chemical industry have not been available on commercially acceptable terms or, in some cases, have been unavailable. In addition, we cannot assure you that in the future we will be able to maintain existing coverage or that our insurance premiums will not increase substantially.

We maintain limited insurance coverage for sudden and accidental environmental damages. We do not believe that insurance coverage for environmental damages that occur over time is available at a reasonable cost. Also, we do not believe that insurance coverage for the full potential liability that could be caused by sudden and accidental incidences is available at a reasonable cost. Accordingly, we may be subject to an uninsured or under-insured loss in such cases.

Our business may be adversely affected by cyclical and seasonal effects.

In general, the chemical industry is cyclical and demand for our wood treating products is somewhat seasonal. Many of our products are used in industries that are cyclical in nature. Changes affecting these industries can adversely affect our revenues and margins. Seasonal usage of our chemical products follows weather conditions, as well as customer marketing programs and requirements. Weather patterns can have an impact on our sales. There can be no assurance that we will adequately address any adverse seasonal effects.

We depend on our senior management team and the loss of any member could adversely affect our operations.

Our success is dependent on the management and leadership skills of our senior management team, including Christopher T. Fraser, our President and Chief Executive Officer, John V. Sobchak, our Chief Financial Officer, Ernest C. Kremling, our Vice President of Operations, Andrew Lau, our Vice President Electronic Chemicals and Roger C. Jackson, our General Counsel. While we have succession plans for these key positions, the loss of any member of our senior management team or an inability to attract, retain and maintain additional qualified personnel could prevent us from implementing our business strategy. We cannot assure you that we will be able to retain our existing senior management personnel or attract additional qualified personnel when needed.

If we are unable to successfully negotiate with the labor unions representing our employees, we may experience a material work stoppage.

About 17.0% of our full-time employees are represented by labor unions, workers councils or comparable organizations, particularly in Mexico and Europe. As our current agreements expire, we cannot assure you that new agreements will be reached at the end of each period without union action, or that a new agreement will be reached on terms satisfactory to us. An extended work stoppage, slowdown or other action by our employees could significantly disrupt our business. Future labor contracts may be on terms that result in higher labor costs to us, which also could adversely affect our results of operations.

11

We are subject to narcotics gang disruption in Mexico and to possible risk of terrorist attacks, each of which could adversely affect our business.

Our penta manufacturing facility is located in Matamoros, Mexico, an area where there has been significant violent crime involving narcotics gang warfare. Our penta operations could be disrupted or otherwise affected by narcotics gang activities in the Mexico border area where our facility is located. We are not insured against terrorist or narcotics gang attacks, and there can be no assurance that losses that could result from an attack on our facilities or personnel, railcars or tank trucks would not have a material adverse effect on our business, results of operations and financial condition. Since September 11, 2001, there has been concern that chemical manufacturing facilities and railcars carrying hazardous chemicals may be at an increased risk of terrorist attacks. Federal, state and local governments have begun a regulatory process that could lead to new regulations impacting the security of chemical industry facilities and the transportation of hazardous chemicals. Our business could be adversely impacted if a terrorist incident were to occur at any chemical facility or while a railcar or tank truck was transporting chemicals.

We are subject to risks inherent in foreign operations, including changes in social, political and economic conditions.

We have facilities in the United States, Mexico, Europe and Singapore, and generate a significant portion of our sales in foreign countries. Like other companies with foreign operations and sales, we are exposed to market risks relating to fluctuations in foreign currency exchange rates. At this time, the Euro is the functional currency of our operations in Europe. We are also exposed to risks associated with changes in the laws and policies governing foreign investments in Mexico, Europe and Asia, and to a lesser extent, changes in United States laws and regulations relating to foreign trade and investment. While such changes in laws, regulations and conditions have not had a material adverse effect on our business or financial condition, we cannot assure you as to the future effect of any such changes.

Although we have sold our animal health products business, we lease our Elwood, Kansas facility to an unrelated party that manufactures animal health products. We believe that all of these properties are adequately insured, in good condition and suitable for their anticipated future use. We believe that if the leases for our offices and facilities in Houston, Fremont, Malaysia and France are not renewed or are terminated, we can obtain other suitable facilities. If our warehouses and facilities in Singapore and the United Kingdom, respectively, were not renewed or terminated, no assurance can be given that we could obtain suitable substitutes without incurring substantial expense. We believe, however, that we will be able to renew our leases on acceptable terms and conditions at the end of their respective terms.

We also have two long-term bulk tank storage agreements with commercial terminal facilities where we store creosote for distribution, and have several storage agreements with commercial warehouses from which we distribute our electronic chemicals. Our bulk storage terminals are on the Mississippi River near New Orleans at Avondale, Louisiana and near Savannah, Georgia. The terminals are used primarily for creosote imported by us from Europe. If our tank storage agreements are not renewed or are terminated, we believe we can obtain other suitable facilities.

We declared and paid a dividend in the first quarter of fiscal year 2014 of $0.03 per share, or approximately $347,000. The current quarterly dividend rate represents an annualized dividend of $0.12 per share. The future payment of dividends, however, will be within the discretion of the Board of Directors and depends on our profitability, capital requirements, financial condition, growth, business opportunities and other factors which our Board of Directors may deem relevant. We repurchased no shares in fiscal years 2013 or 2012.

Our 2009 Long-Term Incentive Plan was submitted to the shareholders and approved at our annual meeting of shareholders on December 8, 2009. Our 2004 Long-Term Incentive Plan was adopted and approved by the shareholders in 2004. Our 1996 Stock Option Plan was adopted and approved by its shareholders in 1996.

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

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the “Selected Financial Data” section of this report and our consolidated financial statements and the related notes and other financial information included elsewhere in this report. In addition to historical financial information, the following discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results and timing of selected events may differ materially from those anticipated in these forward-looking statements as a result of many factors, including those discussed under the section entitled “Risk Factors” and elsewhere in this report.

Introduction

We manufacture, formulate and globally distribute specialty chemicals. We operate specialty chemical businesses selling electronic chemicals and industrial wood treating chemicals. Our electronic chemicals are sold to the semiconductor industry where they are used primarily to clean and etch silicon wafers in the production of semiconductors. Our wood treating chemicals, penta and creosote, are used by industrial customers primarily to extend the useful life of utility poles and railroad crossties.

In fiscal year 2013, approximately 63.0% of our revenues were from electronic chemicals and 37.0% were from industrial wood preservation chemicals.

Our results of operations are impacted by various competitive and other factors including:

• fluctuations in sales volumes;

• raw material pricing and availability;

• our ability to acquire and integrate new products and businesses; and

• the difference between prices received by us for our specialty chemical products and the costs to produce those products.

Acquisition

On May 31, 2013, we completed our acquisition of the ultra pure chemicals (“UPC”) business subsidiaries of OM Group, with facilities located in the United States, the United Kingdom, France and Singapore. The purchase price was $62.6 million. The subsidiaries sell high purity and ultra purity, wet process chemicals to the semiconductor industry. See Note 2 to the consolidated financial statements included in this report.

Sale of the Animal Health Business

On March 1, 2012, we sold certain assets of our animal health business to Bayer Healthcare, LLC for a purchase price of approximately $10.2 million, including $1.0 million held in escrow. The escrowed amount is being held pending final acceptance by the United States Environmental Protection Agency of certain studies being performed at its request on tetrachlorvinphos. We retained the real estate and building at our facility in Elwood, Kansas, but that facility has since been leased for two years to another manufacturer in the animal health business who took over operations there, including our employees. The tenant has an option to purchase the facility.

Results of Operations

Segment Data

Segment data is presented for our two reportable segments for the three fiscal years ended July 31, 2013, 2012 and 2011. The segment data should be read in conjunction with our consolidated financial statements and related notes included elsewhere in this report.

	Year Ended July 31,
	2013		2012		2011
	(Amounts in thousands)
Sales:
Electronic chemicals	$	165,755	$	159,451	$	151,481
Wood treating		97,185		113,034		104,115
Total sales for reportable segments	$	262,940	$	272,485	$	255,596

Segment Sales

In fiscal year 2013, net sales from electronic chemicals were $165.8 million, an increase of $6.3 million, or 4.0%, over net sales of $159.5 million in fiscal year 2012. In fiscal year 2012, net sales in the electronic chemicals segment increased $8.0 million, or 5.3%, over net sales of $151.5 million in fiscal year 2011. In fiscal year 2013, the increase in net sales came from the acquisition of the UPC business subsidiaries of OM Group on May 31, 2013. That acquisition offset the demand decline that we experienced in North America beginning in the second quarter of fiscal year 2013. In fiscal year 2012, the increase in net sales came from greater volume and from price increases implemented to recover higher raw material costs.

Net sales of wood treating chemicals decreased by $15.8 million, or 14.0%, to $97.2 million in fiscal year 2013 from $113.0 million in fiscal year 2012. Net sales of wood treating chemicals in fiscal year 2012 increased by $8.9 million, or 8.6%, from $104.1 million in fiscal year 2011. The decrease in fiscal year 2013 in wood treating products net sales came from a reduction in demand as customers pre-treated railroad ties with a borate solution, and reduced the amount of creosote used in each tie. The increase in net sales of wood treating chemicals for fiscal year 2012 was due to higher sales in both of our wood treating chemical product lines. The increase in fiscal year 2012 in wood treating products net sales came from price increases implemented to recover increased costs.

Segment Income from Operations

Income from operations of the electronic chemicals segment was $14.0 million in fiscal year 2013, as compared to $13.4 million in fiscal year 2012 and $6.2 million in fiscal year 2011. Income from operations of electronic chemicals increased by $600,000, or 4.5% in fiscal year 2013 as compared to the prior year period, and increased by $7.2 million, or 115.8% in fiscal year 2012, as compared to the prior year period.

In fiscal year 2013, income from operations in electronic chemicals was burdened by approximately $577,000 for integration expenses, primarily for consulting services and travel expenses, but benefited by approximately $900,000 from the acquisition of the UPC business. The improvement in income from operations in fiscal year 2012 in electronic chemicals was achieved despite corporate overhead allocated to the segment that was approximately $1.3 million higher than in fiscal year 2011. Approximately half of the $7.2 million improvement came from improved efficiency in our supply chain operations. The balance of the improvement came from improved sales volume and from manufacturing efficiency realized after the consolidation of manufacturing operations from the General Chemical acquisition.

In fiscal year 2013, income from operations of the wood treating segment was $10.5 million as compared to $15.6 million in fiscal year 2012 and $14.8 million in fiscal year 2011. Income from operations for the wood treating segment decreased by $5.1 million, or 32.6% in fiscal year 2013 and increased by $856,000, or 5.8%, in fiscal year 2012 as compared to the respective prior year period.

In fiscal year 2013, income from operations in the wood treating segment suffered from a 16.3% decline in creosote sales volume, primarily because of the move by many customers to pre-treat railroad crossties with borate as a way of reducing the amount of creosote used to treat each crosstie. Income from operations in wood treating chemicals benefited in fiscal year 2012 from higher revenues, although there was a slight decline in operating margin. Overhead allocations to the segment increased by about $1.1 million over the fiscal year 2011. We also had higher costs in fiscal year 2012 of $1.2 million for waste disposal attributable to the segment which were partially offset by a reduction in railcar cleaning and repair expenses of $382,000.

Net Sales and Gross Profit

Net Sales and Gross Profit for Fiscal Year 2013 vs. Fiscal Year 2012

Net sales decreased $9.4 million, or 3.4% in fiscal year 2013 to $263.3 million from $272.7 million in fiscal year 2012. Despite an increase of $6.3 million in net sales from our electronic chemicals segment, net sales were down in the aggregate because of weak demand in North America beginning in the second quarter for electronic chemicals and a decline of approximately $15.8 million in net sales from our wood treating chemicals segment.

Gross profits decreased by $595,000, or 0.8%, to $76.5 million compared to $77.1 million in fiscal year 2012. The decrease in gross profit was the result of the decline in revenue offset by a small increase in the average gross profit margin. Gross profit as a percent of sales increased in fiscal 2013 to 29.0% from 28.3% in fiscal 2012. The small improvement was due to a shift in the weighted average composition of revenues.

Because other companies may include certain of the costs that we record in cost of sales in distribution expenses or selling, general and administrative expenses, and may include certain of the costs that we record in distribution expenses or selling, general and administrative expenses as cost of sales, our gross profit may not be comparable to that reported by other companies.

18

Net Sales and Gross Profit for Fiscal Year 2012 vs. Fiscal Year 2011

Net sales increased $17.1 million, or 6.6% in fiscal year 2012 to $272.7 million from $255.6 million in fiscal year 2011. The increase came on increased sales of $8.0 million from our electronic chemicals segment and $8.9 million from our wood treating chemicals segment.

Gross profit increased in fiscal year 2012 by $9.0 million, or 13.2% to $77.1 million as compared to gross profit of $68.1 million in fiscal year 2011. Approximately half of the improvement in gross profits was due to higher revenues, and half was due to improved gross profit margins. Gross profit as a percent of sales improved in fiscal year 2012 to 28.3% of sales as compared to 26.6% of sales in fiscal year 2011 primarily due to improved margins in our electronic chemicals segment, as we were able to implement pricing increases to recapture cost increases experienced in the prior fiscal year, and because we achieved improved manufacturing efficiency upon completion of our manufacturing consolidation.

Distribution and Selling, General and Administrative Expenses

Distribution and Selling, General and Administrative for Fiscal Year 2013 vs. Fiscal Year 2012

Distribution expenses increased to approximately $30.3 million in fiscal year 2013 from $26.8 million in fiscal year 2012, an increase of about $3.5 million, or 13.2%. The increase in distribution expense was due solely to the acquired electronic chemicals business. Distribution expense as a percent of sales historically has been significantly higher for a newly acquired electronic chemicals business as compared with the current electronic chemicals business. Distribution expense was 11.5% of net sales in fiscal year 2013 and 9.8% in fiscal year 2012. The increase in distribution expense as a percent of net sales in fiscal year 2013 was predominantly due to distribution expense in the UPC business acquired from OM Group. The electronic chemicals segment incurred approximately 82% of our distribution expense in fiscal 2013.

Selling, general and administrative expenses increased to $29.0 million in fiscal year 2013 from $24.9 million in fiscal year 2012, an increase of $4.1 million, or 16.6%. As a percentage of net sales, those expenses were 11.0% and 9.1% in fiscal years 2013 and 2012, respectively. The increase in fiscal year 2013 over the prior year was primarily because of transaction related expenses for our UPC acquisition of $2.1 million, for our integration of that acquisition of $577,000 and for expenses associated with the departure of our former President and CEO, J. Neal Butler of $1.5 million.

Distribution and Selling, General and Administrative for Fiscal Year 2012 vs. Fiscal Year 2011

Distribution expenses decreased to approximately $26.8 million in fiscal year 2012 from $28.8 million in fiscal year 2011, a decrease of about $2.0 million, or 7.1%. The decrease in distribution expense resulted from efficiency improvements in our electronic chemicals segment supply chain costs from the completion of the integration of the General Chemical acquisition. Distribution expense was 9.8% of net sales in fiscal year 2012 and 11.3% in the prior year. The electronic chemicals segment incurred approximately three-quarters of our distribution expense in fiscal year 2012.

Selling, general and administrative expenses increased to $24.9 million in fiscal year 2012 from $22.2 million in fiscal year 2011, an increase of $2.6 million, or 11.9%. As a percentage of net sales, those expenses were 9.1% and 8.7% in fiscal years 2012 and 2011, respectively. The increase in fiscal year 2012 over the prior year was primarily because of higher employee related costs of $1.6 million and waste disposal costs of $1.2 million for waste disposal at our Tuscaloosa facility and disposal of waste associated with cleaning rail cars in creosote service.

19

Interest Expense

Interest expense was $1.8 million in fiscal year 2013, $2.1 million in fiscal year 2012 and $2.3 million in fiscal year 2011. We increased borrowings under our credit facility to complete our acquisitions in electronic chemicals with a purchase in May 2013 from OM Group and a purchase in March 2010 from General Chemical. Between those two acquisitions we reduced the amount of those borrowings.

Income Taxes

We had income tax expense from continuing operations of $5.7 million, $8.8 million and $5.1 million in fiscal years 2013, 2012 and 2011, respectively. Our effective tax rate was 37.6% in fiscal year 2013, 37.9% in fiscal year 2012 and 35.0% in fiscal year 2011. In general, differences between these effective tax rates and the United States statutory rate of 35.0% are primarily due to acquisition-related charges and state income taxes, with a partial offset of various changes in tax law in 2013 and state income taxes in fiscal year 2012. Excluding acquisition related costs the effective tax rate was 32.9% at July 31, 2013.

Discontinued Operations

Discontinued operations reflected a loss before income taxes of $203,000 and $711,000 for fiscal years 2013 and 2012, respectively, and income before taxes of $514,000 for fiscal year 2011.

In fiscal year 2008, we discontinued operations of our herbicide product line that had comprised the agricultural chemical segment. We incurred costs of $121,000, $599,000 and $120,000 in the fiscal years ended July 31, 2013, 2012 and 2011, respectively, for dismantling the herbicide facility and for medical and other expenses associated with an accident that occurred in fiscal year 2012 while the facility was being dismantled.

On March 1, 2012, we sold the business that had comprised our animal health segment to Bayer Healthcare LLC. For the fiscal year ended July 31, 2013 and 2012, $82,000 and $112,000 was reported as a loss from discontinued operations before income taxes. In fiscal year 2013 the loss included $57,000 for a post-closing inventory adjustment that was recognized as loss on sale of the business in the first fiscal quarter, and in fiscal year 2012 the loss included the gain on sale of approximately $90,000.

Liquidity and Capital Resources

Cash Flows

Net cash provided by operating activities was $20.3 million in fiscal year 2013, $25.2 million in fiscal year 2012 and $12.7 million in fiscal year 2011.

In fiscal year 2013, operating cash flow was favorably impacted by a $5.3 million increase in accounts payable, primarily from the timing of creosote inventory purchases and by a $1.8 million decrease in trade accounts receivable. Trade accounts receivable decreased because of lower electronic chemical sales in the fourth quarter of fiscal year 2013 as compared to the same period in the prior year. Operating cash flow was unfavorably impacted by an increase in accounts receivable-other of $2.6 million, primarily from payments of estimated income taxes for the current period.

In fiscal year 2012, cash flows from operating activities were favorably impacted by a decrease in accounts receivable of $6.8 million, primarily due to lower sales of creosote during the fourth quarter of fiscal year 2012 as compared to the prior year fourth fiscal quarter, and to a lesser extent because of the sale of the animal health business and currency translation adjustments of our Italian subsidiary’s accounts receivable balance on lower currency exchange rates. Cash flows were also favorably impacted by an increase in accrued liabilities and a decrease in other receivables of $1.9 million and $2.2 million, respectively. The increase in accrued liabilities was mainly due to a higher employee incentive accrual of approximately $1.1 million, while the decrease in other receivables included a reduction in income taxes receivable applied to the current period tax payments. Cash flows from operating activities were unfavorably impacted by a decrease in our trade accounts payable and an increase in inventories of $2.8 million and $5.5 million, respectively. The decrease in accounts payable was due primarily to the timing of payments on our creosote purchases and lower freight accruals, while the increase in inventories was attributable to our creosote inventories due to the combination of higher quantities, higher average cost and material in transit at the end of the current year. We also had higher inventories in our electronic chemicals segment due to increased raw material purchases at the end of fiscal year 2012. All results reported were net of the sale of our animal health business which reduced our working capital requirements.

In fiscal year 2011, cash flows from operating activities were favorably impacted by an increase in accounts payable of $3.8 million, primarily from the timing of payments for our creosote purchases and increased activity in our electronic chemicals segment related to increased production and sales volume. Cash flows from operating activities was unfavorably impacted by increases in our trade accounts receivables and inventories of $5.9 million and $2.2 million, respectively. The increase in accounts receivable was due to higher creosote sales, while the increase in inventories was attributable to our increased electronic chemicals business.

20

In fiscal year 2013, cash used in investing activities was $68.1 million compared to cash provided by investing activities of $4.0 million in fiscal year 2012. In fiscal year 2013, $62.6 million was used to acquire the UPC business of the OM Group, which was net of cash acquired, and $5.5 million was invested in property, plant and equipment, about $4.2 million of which was invested in our legacy electronic chemicals business. The rest of the capital expenditure was primarily for various equipment and additions across our other facilities.

Net cash provided by investing activities was $4.0 million in fiscal year 2012 compared to cash used of $8.0 million in fiscal year 2011. In fiscal year 2012, we made $5.2 million of additions to property, plant and equipment, approximately $4.3 million of which was for electronic chemicals production and distribution equipment. The remainder of our additions to property was capital expenditures for normal equipment and system upgrades and purchases at our different locations. We received $10.2 million of proceeds for the sale of our animal health business during fiscal year 2012.

In fiscal year 2011, we made $8.3 million of additions to property, plant and equipment, approximately $1.9 million of which was in connection with our integration efforts at our Hollister, California facility. We spent approximately $4.6 million at our Pueblo facility primarily for the purchase of tank wagons, shipping containers and equipment related to our sulfuric acid business, and to a lesser extent for our integration efforts. The remainder of our additions to property was for normal capital expenditures.

In fiscal year 2013, net cash from financing activities was $60.0 million including $61.0 million of net borrowings on our revolving credit facility to finance the purchase of the UPC business.

In fiscal year 2012, net cash used in financing activities was $29.3 million. We reduced our revolving facility by $13.9 million and paid $11.3 million to pay off our term loan. In fiscal year 2011, net cash used in financing activities was $7.8 million. We reduced our revolving facility by $2.1 million, reduced our term loan by $8.0 million and also cleared the book overdraft that had been outstanding at July 31, 2011.

We paid dividends of $1.4 million, $1.2 million and $1.0 million in fiscal years 2013, 2012 and 2011, respectively.

Working Capital

We have a revolving line of credit under an amended and restated credit agreement. At July 31, 2013, we had $65.0 million outstanding under that revolving facility and a maximum $41.6 million in additional borrowing capacity, after giving effect to a reduction of $3.4 million for unused letters of credit. The actual amount available under the revolving facility at July 31, 2013 was limited, however, to approximately $18.7 million, because of a loan covenant restriction respecting funded debt to pro-forma earnings before interest, taxes and depreciation. We increased the maximum borrowing capacity available under our revolving line in April 2013 and May 2013 in anticipation of the acquisition of the UPC business subsidiaries of OM Group. Management believes that our current credit facility, combined with cash flows from operations, will adequately provide for our working capital needs for current operations for the next twelve months.

Long Term Obligations

Our long-term debt and current maturities as of July 31, 2013 and July 31, 2012 consisted of the following (in thousands):

	July 31, 2013		July 31, 2012
Senior Secured Debt:
Note Purchase Agreement, maturing on December 31, 2014, interest rate of 7.43%	$	20,000	$	20,000
Revolving Loan Facility, maturing on April 30, 2018, variable interest rates based on LIBOR plus 1.50% and 2.0% at July 31, 2013 and 2012, respectively		65,000		4,000
Total debt		85,000		24,000
Current maturities of long-term debt		—		—
Long-term debt, net of current maturities	$	85,000	$	24,000

To finance the acquisition of the electronic chemicals business in December 2007, we entered into an amended and restated credit agreement and a note purchase agreement. The amended and restated credit agreement is now with Wells Fargo Bank, National Association, and with Bank of America, N.A. The note purchase agreement is now with The Prudential Insurance Company of America and Pruco Life Insurance Company.

21

Initially, the amended and restated credit agreement included a revolving loan facility and a term loan facility. We amended these facilities several times, most recently in April 2013 and May 2013, to increase the amount that may be borrowed under the revolving loan up to $110.0 million, including an accordion feature that allows for an additional revolving loan increase of up to $25.0 million with approval from our lenders, and to extend the maturity date of the revolving loan facility to April 30, 2018, with mandatory reduction in the revolving loan commitment of $10.0 million each year from September 30, 2014 to September 30, 2017 totaling $40.0 million. We recorded $229,000 of financing costs in connection with the amendment of the revolving loan facility. The matrix for the calculation of interest payable on the revolving loan facility and the method for the calculation of the fixed charge coverage ratio were also revised.

The revolving loan bears interest at varying rate of LIBOR plus a margin based on funded debt to earnings before interest, taxes, depreciation and amortization (“EBITDA”), as described in the table.

Ratio of Funded Debt to EBITDA	Margin
Equal to or greater than 2.5 to 1.0		2.25	%
Equal to or greater than 2.0 to 1.0, but less than 2.5 to 1.0		2.00	%
Equal to or greater than 1.5 to 1.0, but less than 2.0 to 1.0		1.75	%
Less than 1.5 to 1.0		1.50	%

We also incur an unused commitment fee on the unused amount of commitments under revolving loan facility of 0.35% or 0.25% based on ratio of funded debt to EBITDA. Advances under the revolving loan bear interest at 1.69% and 2.2% as of July 31, 2013 and 2012, respectively. The amount outstanding on the revolving loan facility was $65.0 million at July 31, 2013.

During the first quarter of fiscal year 2012, we repaid the outstanding balance of the term loan with borrowings on the revolving loan and in a November 2011 amendment, that aspect of the facility was deleted.

The note purchase agreement is for $20.0 million. Advances under the note purchase agreement mature December 31, 2014, and bears interest at 7.43% per annum. Principal is payable at maturity. At July 31, 2013, $20.0 million was outstanding under the note purchase agreement.

Loans under the amended and restated credit facility and the note purchase agreement are secured by our assets, including stock in subsidiaries, inventory, accounts receivable, equipment, intangible assets, and real property. The credit facility and the note purchase agreement have restrictive covenants, including requirements that we must maintain a fixed charge coverage ratio of 1.5 to 1.0, a ratio of funded debt to EBITDA (as adjusted for extraordinary items, with lender consent) of 3.0 to 1.0 and a current ratio of at least 1.5 to 1.0.

Principal payments due under long-term debt agreements for the fiscal years ended July 31 are as follows (in thousands):

	Total		2014		2015		2016		2017		2018		Thereafter
Long-term debt	$	85,000	$	—	$	20,000	$	—	$	—	$	65,000	$	—

Environmental Expenditures

Our capital expenditures and operating expenses for continuing operations for environmental matters, excluding testing, data submission and other costs associated with our product task force participation, were approximately $1.3 million in fiscal year 2013, $2.2 million in fiscal year 2012 and $1.7 million in fiscal year 2011.

We expensed approximately $522,000 for testing, data submission and other costs associated with our participation in product task forces for continuing operations in fiscal year 2013, and approximately $802,000 and $760,000 in fiscal years 2012 and 2011, respectively. We estimate that we will continue to incur additional testing, data submission and other costs for continuing operations of approximately $545,000 in fiscal year 2014. Since environmental laws have traditionally become increasingly stringent, costs and expenses relating to environmental control and compliance may increase in the future. While we do not believe that the incremental cost of compliance with existing or future environmental laws and regulations will have a material adverse effect on our business, financial condition or results of operations, we cannot assure that costs of compliance will not exceed current estimates.

22

Contractual Obligations

Our obligations to make future payments under contracts as of July 31, 2013 are summarized in the following table (in thousands):

	Payments Due by Period (in thousands)
	Total		1 Year		2-5 Years		More than 5 Years
Long-term debt	$	85,000	$	—	$	85,000	$	—
Estimated interest payments on debt (1)		10,145		2,540		7,605		—
Operating leases		11,942		3,748		5,139		3,055
Other long-term liabilities (2)		1,822		173		441		1,208
Purchase obligations (3)		189,508		70,283		119,225		—
Total	$	298,417	$	76,744	$	217,410	$	4,263

(1) Estimated payments are based on interest rates in effect as of the end of July 2013.

(2) Primarily includes post retirement benefit obligations for a supplemental executive retirement plan for one of our former United States executives and in connection with benefit obligations of our foreign subsidiaries.

(3) Consists primarily of raw materials purchase contracts. These are typically not fixed prices arrangements. The prices are based on the prevailing prices.

Outlook for Fiscal Year 2014

We anticipate global semiconductor industry production will increase moderately in fiscal year 2014, with production progressively improving over the course of the year. Meanwhile, we expect continued steady market demand for wood railroad ties and improving demand for utility poles as western U.S.-based utilities upgrade their distribution infrastructure.

As we integrate OM Group’s UPC subsidiaries into our operations, we anticipate fiscal year 2014 will be a transition year in terms of our overall financial performance. We expect that consolidated net sales will exceed $350.0 million in fiscal year 2014, due primarily to the addition of sales from our recent acquisition. However, we anticipate moderate net income growth in fiscal year 2014, as we incur costs to reconfigure our electronic chemicals manufacturing and supply chain operations in Europe, and shift production from our Fremont, California site to our larger manufacturing facilities in Hollister, California and Pueblo, Colorado. We believe the costs of that effort will range between approximately $4.0-$5.0 million in fiscal year 2014, and project this restructuring, once completed in fiscal year 2015, will improve annualized operating income in our electronic chemicals segment by $6.0-8.0 million.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, such as financing or unconsolidated variable interest entities, other than operating leases.

23

Recent Accounting Standards

We have considered all recently issued accounting standards updates and SEC rules and interpretive releases.

In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a similar Tax Loss, or a Tax Credit Carryforward Exists.” The update was issued to reduce the diversity in presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The update requires an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, with certain exceptions listed in the update. The new presentation requirements are effective for interim and annual periods beginning after December 15, 2013. Since this update only affects presentation of unrecognized tax benefits in financial statements, adoption of this standard is not expected to have a material impact on the our financial statements.

Critical Accounting Policies

Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America. The preparation of these consolidated financial statements requires the use of estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the periods presented. The significant accounting principles that we believe are the most important to aid in fully understanding our financial results are the following:

Revenue Recognition — Our chemical products are sold in the open market and revenue is recognized when risk of loss and title to the products transfers to customers. In general, risk of loss transfers upon shipment to customers. We also recognize service revenue in connection with technical support services and chemicals delivery and handling at customer facilities. Revenue is recognized as those services are provided.

Allowance for Doubtful Accounts — We record an allowance for doubtful accounts to reduce accounts receivable where we believe accounts receivable may not be collected. A provision for bad debt expense recorded to selling, general and administrative expenses increases the allowance. Accounts receivable that are written off decrease the allowance. The amount of bad debt expense recorded each period and the resulting adequacy of the allowance at the end of each period are determined using a customer-by-customer analyses of accounts receivable balances each period and subjective assessments of future bad debt exposure. Historically, write offs of accounts receivable balances have been insignificant. The allowance was $224,000 and $16,000 at July 31, 2013 and 2012, respectively.

Goodwill — The carrying value of goodwill is reviewed at least annually, and if this review indicates that it will not be recoverable, our carrying value of goodwill will be adjusted to fair value. Based on an assessment of qualitative factors it was determined that there were no events or circumstances that would lead us to a determination that is more likely than not that the fair value of the applicable reporting unit was less than the carrying value as of July 31, 2013 and 2012. Accordingly, we determined that as of July 31, 2013 and 2012, goodwill was not impaired. We perform a similar assessment for intangible assets with indefinite lives. Based on that assessment, we determined that there was no impairment of these intangible assets during fiscal years 2013, 2012 and 2011.

Impairment of Long-Lived Assets — Long-lived assets, including property, plant and equipment, and intangible assets, with defined lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset or its disposition. The measurement of an impairment loss for long-lived assets, where management expects to hold and use the asset, are based on the asset’s estimated fair value. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value.

Income Taxes — Deferred income taxes and liabilities are determined using the asset and liability method in accordance with accounting principles generally accepted in the United States of America. We have deferred tax assets that are reviewed periodically for recoverability. These assets are evaluated by using estimates of future taxable income streams. Valuations related to tax accruals and assets could be impacted by changes to tax codes, changes in the statutory tax rates and our future taxable income levels. A portion of the net deferred tax asset is related to net operating losses from a foreign subsidiary, which have no time expiration. As of July 31, 2013 we had no valuation allowance, as we concluded that it is more likely than not that the deferred tax asset related to the net operating losses of the foreign subsidiary will be realized based on pre-tax income realized for the last two years and projected earnings.

Our subsidiary in Italy is currently under examination for the period ended July 31, 2009 respecting certain registration tax assessments. See Note 8 to the financial statements included in this report.

Inventory— Inventories are valued at the lower of cost or market. For certain products, cost is generally determined using the first-in, first-out (“FIFO”) method. For certain other products we utilize a weighted-average cost. We record inventory obsolescence as a reduction in inventory when considered unsellable. We review inventories periodically to ensure the valuation of these assets is recorded at the lower of cost or market and to record an obsolescence reserve when inventory is considered unsellable. During the fiscal years ended July 31, 2013 and 2012, we recognized inventory valuation adjustments of $355,000 and $371,000, respectively. As of July 31, 2013 and 2012, we had $180,000 and $493,000, respectively, of reserves for inventory obsolescence.

Disclosure Regarding Forward Looking Statements

We are including the following discussion to inform our existing and potential security holders generally of some of the risks and uncertainties that can affect us and to take advantage of the “safe harbor” protection for forward-looking statements that applicable federal securities law affords. From time to time, our management or persons acting on our behalf make forward-looking statements to inform existing and potential security holders about our company. These forward-looking statements include information about possible or assumed future results of our operations. All statements, other than statements of historical facts, included or incorporated by reference in this report that address activities, events or developments that we expect or anticipate may occur in the future, including such things as future capital expenditures, business strategy, competitive strengths, goals, growth of our business and operations, plans and references to future successes may be considered forward-looking statements. Also, when we use words such as “anticipate,” “believe,” “estimate,” “intend,” “plan,” “project,” “forecast,” “may,” “should,” “budget,” “goal,” “expect,” “probably” or similar expressions, we are making forward-looking statements. Many risks and uncertainties may impact the matters addressed in these forward-looking statements. Our forward-looking statements speak only as of the date made and we will not update forward-looking statements unless the securities laws require us to do so.

Some of the key factors which could cause our future financial results and performance to vary from those expected include:

• the loss of primary customers;

• our ability to implement productivity improvements, cost reduction initiatives or facilities expansions;

• market developments affecting, and other changes in, the demand for our products and the entry of new competitors or the introduction of new competing products;

• availability or increases in the price of energy, our primary raw materials and active ingredients;

• the timing of planned capital expenditures;

• our ability to identify, develop or acquire, and market additional product lines and businesses necessary to implement our business strategy and our ability to finance such acquisitions and development;

• the condition of the capital markets generally, which will be affected by interest rates, foreign currency fluctuations and general economic conditions;

• cost and other effects of legal and administrative proceedings, settlements, investigations and claims, including environmental liabilities which may not be covered by indemnity or insurance;

• the effects of weather, earthquakes, other natural disasters and terrorist attacks;

• the ability to obtain registration and re-registration of our products under applicable law;

• the political and economic climate in the foreign or domestic jurisdictions in which we conduct business; and

• other United States or foreign regulatory or legislative developments which affect the demand for our products generally or increase the environmental compliance cost for our products or impose liabilities on the manufacturers and distributors of such products.

The information contained in this report, including the information set forth under the heading “Risk Factors”, identifies additional factors that could cause our results or performance to differ materially from those we express in our forward-looking statements. Although we believe that the assumptions underlying our forward-looking statements are reasonable, any of these assumptions and, therefore, the forward-looking statements based on these assumptions, could themselves prove to be inaccurate. In light of the significant uncertainties inherent in the forward-looking statements which are included in this report and the exhibits and other documents incorporated herein by reference, our inclusion of this information is not a representation by us or any other person that our objectives and plans will be achieved.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to certain market risks in the ordinary course of our business, arising primarily from changes in interest rates and to a lesser extent foreign currency exchange rate fluctuations. Generally we do not utilize derivative financial instruments or hedging transactions to manage that risk.

Interest Rate Sensitivity

As of July 31, 2013, our fixed rate debt consisted of $20.0 million of term notes with an interest rate of 7.43%, maturing on December 31, 2014.

Our variable rate debt as of July 31, 2013 consisted of a revolving loan advanced under our credit facility with an interest rate of 1.69% (1.5% plus LIBOR), maturing on April 30, 2018. On July 31, 2013, we had $65.0 million borrowed on the revolving loan under that facility.

Based on the outstanding balance of our variable rate debt and applicable interest rate at July 31, 2013, taking into account anticipated principal payments, a 1.0% change in the interest rate as of July 31, 2013 would result in a change of approximately $620,000 in annual interest expense.

Foreign Currency Exchange Rate Sensitivity

We are exposed to fluctuations in foreign currency exchange rates from international operations in the electronic chemicals segment. Our international operations in Europe and Singapore use different functional currencies, including the Euro, Great Britain Pound and Singapore Dollar. The U.S. Dollar is our consolidated reporting currency. Currency translation gains and losses result from the process of translating those operations from the functional currency into our reporting currency. Currency translation gains and losses have no impact on the consolidated statements of income and are recorded as accumulated other comprehensive income or loss within stockholders’ equity in our consolidated balance sheets. Assets and liabilities have been translated using exchange rates in effect at the balance sheet dates. Revenues and expenses have been translated using the average exchange rates during the period.

We recognized a foreign currency translation gains of $1.8 million and $2.1 million in fiscal years 2013 and 2011, respectively, and a loss of $3.1 million in fiscal year 2012, each of which were included in accumulated other comprehensive loss in the consolidated balance sheets. At July 31, 2013, the cumulative foreign currency translation loss reflected in accumulated other comprehensive loss was $2.5 million.

Additionally we have limited exposure to certain transactions denominated in a currency other than the functional currency in our European and Singapore operations. Accordingly, we recognize exchange gains or losses in our consolidated statement of income from these transactions. We believe the impact of changes in foreign currency exchange rates do not have a material effect on our results of operations or cash flows.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

KMG Chemicals, Inc.:

We have audited KMG Chemicals, Inc.’s internal control over financial reporting as of July 31, 2013, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). KMG Chemicals, Inc.’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 KMG Chemicals, Inc.’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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.

In our opinion, KMG Chemicals, Inc. maintained, in all material respects, effective internal control over financial reporting as of July 31, 2013, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

KMG Chemicals, Inc. acquired the ultra pure chemicals business subsidiaries of OM Group, Inc. (“the UPC Business”) during 2013, and management excluded from its assessment of the effectiveness of KMG Chemicals, Inc.’s internal control over financial reporting as of July 31, 2013, the UPC Business’ internal control over financial reporting associated with total assets of approximately $75 million and total revenues of approximately $16 million included in the consolidated financial statements of KMG Chemicals, Inc. and subsidiaries as of and for the year ended July 31, 2013. Our audit of internal control over financial reporting of KMG Chemicals, Inc. also excluded an evaluation of the internal control over financial reporting of the UPC Business.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of KMG Chemicals, Inc. and subsidiaries as of July 31, 2013 and 2012, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the two-year period ended July 31, 2013, and our report dated October 29, 2013 expressed an unqualified opinion on those consolidated financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

General — KMG Chemicals, Inc. (the “Company”) is involved principally in the manufacture, formulation and distribution of specialty chemicals in carefully focused markets through its two wholly-owned subsidiaries, KMG Electronic Chemicals, Inc. (“KMG EC”) and KMG-Bernuth, Inc. (“KMG Bernuth”).

In its electronic chemicals business, the Company sells high purity wet process chemicals to the semiconductor industry, and in the wood treating chemicals business the Company sells two industrial wood treating chemicals, pentachlorophenol (“penta”) and creosote. The Company operates its electronic chemicals business through KMG EC in North America and through KMG Italia, S.r.l. (“KMG Italia”) and KMG Electronic Chemicals Holdings S.a.r.l (“KMG Lux”) (and its subsidiaries) in Europe and elsewhere. That business has facilities in the United States, the United Kingdom, France, Italy and Singapore. In the wood treating business the Company manufactures penta at its plant in Matamoros, Mexico through KMG de Mexico (“KMEX”), a Mexican corporation which is a wholly-owned subsidiary of KMG Bernuth. The Company sells its wood treating chemicals in the United States, Mexico and Canada. The electronic chemicals and wood treating businesses constitute two reportable segments that the Company considers of equal importance. See Note 13.

Principles of Consolidation — The consolidated financial statements include the accounts of KMG Chemicals, Inc. and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“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 these estimates.

Reclassifications — Certain reclassifications of prior year amounts have been made to conform to current year presentation.

Cash and Cash Equivalents — The Company considers all investments with original maturities of three months or less when purchased to be cash equivalents. The Company reduces cash balances when checks are disbursed. Due to the time delay in checks clearing the banks, the Company reports a negative balance in its cash disbursement accounts as a current liability which is reflected as book overdraft in the consolidated balance sheets. The Company did not have a negative cash balance as of July 31, 2013.

Restricted Cash — Restricted cash includes cash balances which are legally or contractually restricted to use. The Company’s restricted cash as of July 31, 2013 and 2012 includes proceeds that were placed in escrow in connection with the sale of the animal health business. See Note 12.

Fair Value of Financial Instruments — The carrying value of financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable approximate fair value because of the relatively short maturity of these instruments. The fair value of the Company’s debt at July 31, 2013 and 2012 approximated its carrying value since the debt obligations bear interest at a rate consistent with market rates.

Accounts Receivable — The Company’s trade accounts receivable are primarily from wood-treating customers and from electronic chemical customers worldwide. The Company extends credit based on an evaluation of the customer’s financial condition, generally without requiring collateral. Exposure to losses on receivables is dependent on each customer’s financial condition. At July 31, 2013 there were two customers that represented approximately 12% and 14%, respectively of the Company’s accounts receivable, and at July 31, 2012 there were two customers that represented approximately 12% and 17%, respectively, of the Company’s accounts receivable.

The Company records an allowance for doubtful accounts to reduce accounts receivable when the Company believes an account may not be collected. A provision for bad debt expense is recorded to selling, general and administrative expenses. The amount of bad debt expense recorded each period and the resulting adequacy of the allowance at the end of each period are determined using a customer-by-customer analyses of accounts receivable balances each period and our assessment of future bad debt exposure. Historically, write offs of accounts receivable balances have been insignificant. The allowance was $224,000 and $16,000 at July 31, 2013 and 2012, respectively.

Inventories — Inventories are valued at the lower of cost or market. For certain products, cost is generally determined using the first-in, first-out (“FIFO”) method. For certain other products the Company utilizes a weighted-average cost. The Company records inventory obsolescence as a reduction in its inventory when considered unsellable.

Property, Plant, and Equipment — Property, plant, and equipment are stated at cost less accumulated depreciation and amortization. Major renewals and betterments are capitalized. Repairs and maintenance costs are expensed as incurred.

36

Depreciation for equipment commences once placed in service, and depreciation for buildings and leasehold improvements commences once they are ready for their intended use. Depreciable life is determined through economic analysis. Depreciation for financial statement purposes is provided on the straight-line method.

The estimated useful lives of classes of assets are as follows:

Asset Class	Life (Years)
Building	15 to 30
Plant	10 to 18
Equipment	3 to 15
Leasehold improvements	remaining life of the lease

Depreciation expense was approximately $7.7 million, $6.5 million and $6.3 million in fiscal years 2013, 2012 and 2011, respectively.

Intangible Assets — Identifiable intangible assets with a defined life are amortized using a straight-line or accelerated method over the useful lives of the assets. Identifiable intangible assets of an indefinite life are not amortized. These assets are required to be tested for impairment at least annually. If this review indicates that impairment has occurred, the Company’s carrying value of intangibles will be adjusted to fair value. Based on an assessment of qualitative factors, in accordance with GAAP, it was determined that there were no events or circumstances that would lead the Company to a determination that is more likely than not that the fair value of the applicable assets was less than its carrying value as of July 31, 2013 and 2012. The Company concluded that as a result its indefinite lived intangible assets were not impaired as of July 31, 2013 and 2012. It is the Company’s policy to expense costs as incurred in connection with the renewal or extension of its intangible assets.

Goodwill — The Company has goodwill of $3.8 million and $7.1 million, respectively, associated with its wood treating and electronic chemicals segments. The carrying value of the Company’s goodwill is reviewed at least annually, and if this review indicates that it will not be recoverable the Company’s carrying value of goodwill will be adjusted to fair value. Based on an assessment of qualitative factors it was determined that there were no events or circumstances that would lead the Company to a determination that is more likely than not that the fair value of the applicable reporting unit was less than its carrying value as of July 31, 2013 and 2012. Accordingly, the Company determined that as of July 31, 2013 and 2012, goodwill was not impaired. As a result, there was no change in the carrying value of goodwill as of July 31, 2013 and 2012, respectively, except for an increase in goodwill of $7.1 million in connection with the acquisition of the electronic chemicals business subsidiaries of OM Group, Inc. See Note 2.

Impairment of Long-Lived Assets — Long-lived assets, including property, plant and equipment, and intangible assets with defined lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its disposition. The measurement of an impairment loss for long-lived assets, where management expects to hold and use the asset, are based on the asset’s estimated fair value. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value.

Revenue Recognition — The Company’s chemical products are sold in the open market and revenue is recognized when risk of loss and title to the products transfers to customers. In general, risk of loss transfers upon shipment to customers. The Company also recognizes service revenue in connection with technical support services and chemicals delivery and handling at customer facilities. Revenue is recognized as those services are provided.

Cost of Sales — Cost of sales includes inbound freight charges, purchasing and receiving costs, depreciation, inspection costs and internal transfer costs. In the case of products manufactured by the Company, direct and indirect manufacturing costs (including depreciation and amortization) and associated plant administrative expenses are included as well as laid-in cost of raw materials consumed in the manufacturing process.

Distribution Expenses — These expenses include outbound freight, depreciation, storage and handling expenses and other miscellaneous costs (including depreciation and amortization) associated with product storage, handling and distribution.

Selling, General and Administrative Expenses — These expenses include selling expenses, corporate headquarters’ expenses, amortization of intangible assets and environmental regulatory support expenses.

Advertising Costs — Our policy is to expense advertising costs as they are incurred. Advertising costs were approximately $26,000, $347,000 and $608,000 in fiscal years ended July 31, 2013, 2012 and 2011, respectively. These costs were primarily related to the animal health business which is reported as discontinued operations in the consolidated statements of income. See Note 12.

37

Shipping and Handling Costs — Shipping and handling costs are included in cost of sales and distribution expenses. Inbound freight charges and internal transfer costs are included in cost of sales. Product storage and handling costs and the cost of distributing products to the Company’s customers are included in distribution expenses.

Income Taxes — The Company files a consolidated United States federal income tax return, and for financial reporting purposes, provides income taxes for the differences between the financial statement carrying amounts of assets and liabilities and their tax bases in accordance with GAAP. See Note 5.

Earnings Per Share — Basic earnings per common share amounts are calculated using the average number of common shares outstanding during each period. Diluted earnings per share assumes the issuance of restricted stock awards and the exercise of stock options having exercise prices less than the average market price during the period of the common stock, using the treasury stock method.

Foreign Currency Translation — The functional currency of the Company’s Mexico operations is the U.S. Dollar. As a result, monetary assets and liabilities for KMEX are re-measured to U.S. dollars at current rates at the balance sheet dates, income statement items are re-measured at the average monthly exchange rates for the dates those items were recognized, and certain assets (including plant and production equipment) are re-measured at historical exchange rates. Foreign currency transaction gains and losses are included in the statement of operations as incurred along with gains and losses from currency re-measurement. These gains and losses were nominal in fiscal years 2013, 2012 and 2011.

The Company’s international operations in the electronic chemicals business are in Europe and Singapore, and use local currencies as the functional currency, including the GB Pound, Euro and Singapore Dollar. The translation adjustment resulting from currency translation of the local currency into the reporting currency (U.S. Dollar) is included as a separate component of stockholders’ equity. The assets and liabilities have been translated from local currencies into U.S. Dollars using exchange rates in effect at the balance sheet dates. Results of operations have been translated using the average exchange rates during the period. Foreign currency translation resulted in a translation adjustment gains of $1.8 million and $2.1 million in fiscal years 2013 and 2011, respectively, and a loss of $3.1 million in fiscal years 2012, each of which are included in accumulated other comprehensive loss in the consolidated balance sheets.

Stock-Based Compensation — The Company’s stock-based compensation expense is based on the fair value of the award measured on the date of grant. For stock option awards, the grant date fair value is measured using a Black-Scholes option valuation model. For stock awards, the Company’s stock price on the date of the grant is used to measure grant date fair value. For awards of stock which are based on a fixed monetary value the grant date fair value is based on the monetary value. Stock-based compensation costs are recognized as an expense over the requisite service period of the award using the straight-line method.

Recent Accounting Standards

The Company has considered all recently issued accounting standards updates and SEC rules and interpretive releases.

In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a similar Tax Loss, or a Tax Credit Carryforward Exists.” The update was issued to reduce the diversity in presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The update requires an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, with certain exceptions listed in the update. The new presentation requirements are effective for interim and annual periods beginning after December 15, 2013. Since this update only affects presentation of unrecognized tax benefits in financial statements, adoption of this standard is not expected to have a material impact on the Company’s financial statements.

2. ACQUISITIONS

On May 31, 2013, the Company completed its acquisition of the ultra pure chemicals (“UPC”) business subsidiaries of OM Group, Inc. (“OM Group”) located in the United States, Europe and Singapore. The aggregate purchase price consists of cash paid at closing of $63.3 million reduced by approximately $684,000 of working capital adjustments. The subsidiaries sell high purity and ultra pure, wet process chemicals to the semiconductor industry. The Company completed the acquisition by borrowing $65.0 million on the revolving loan under a revised credit facility on May 31, 2013. See Note 7 for further discussion of the Company’s revised credit facility.

The Company accounted for the acquisition under the acquisition method of accounting in accordance with GAAP. During the year ended July 31, 2013, the Company expensed transaction and acquisition-related costs of approximately $2.1 million, which is included in selling, general and administrative expenses on the Company’s consolidated statement of income.

As of July 31, 2013, the Company has $3.8 million foreign net operating losses carryforwards which do not expire.

The Company records provisions for uncertain tax provisions in accordance with GAAP, which prescribes the minimum recognition threshold that a tax position is required to meet before being recognized in the financial statements. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. The statute of limitations remain open for fiscal year ended July 31, 2010 and forward for United States federal income taxes and fiscal year ended July 31, 2008 and forward for state tax jurisdictions.

The Company’s subsidiary in Italy is currently under examination for the period ended July 31, 2009. Adjustments were proposed by the taxing authority at the end of April 2011 that would result in approximately $1.6 million (including interest and penalties) of additional liability, if all the adjustments are sustained. However, the Company does not expect all of this amount to result in cash payments, as the Company would be able to utilize available net operating losses. The Company has provided additional information and additional documentary evidence in response to the proposed adjustments, and intends to vigorously defend its tax position. The ultimate outcome of this examination is subject to uncertainty, and the Company recorded a liability for its uncertain tax position in Italy in fiscal year 2013 in the amount of $437,000, which includes penalties and interest. These uncertain tax positions primarily relate to transfer pricing.

On January 2, 2013 the American Taxpayer Relief Act was adopted. The law included a retroactive two year extension of the research and development credit from January 1, 2012 through December 31, 2013. A retroactive income tax benefit of approximately $200,000 was recorded by the Company. In July 2013, The Finance Bill 2013 included reductions in the United Kingdom corporation tax rate to 21%, effective April 2014.

Undistributed earnings of the Company’s Mexico subsidiary amount to approximately $5.6 million at July 31, 2013. Those earnings are considered to be permanently reinvested. For the year ended July 31, 2012, the Company implemented an annual dividend policy plan for Mexico up to its current year earnings and profits. It is the Company’s intention to continue to remain permanently invested in Mexico on its prior year cumulative undistributed earnings. Accordingly, no provision for United States income taxes has been provided with respect to these undistributed earnings. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company will be subject to both United States income taxes (subject to an adjustment for foreign tax credits) and potential withholding taxes payable to the foreign country. Determination of the amount of unrecognized deferred United States income tax liability is not practicable due to the complexities associated with its hypothetical calculation.

41

The following table accounts for the differences between the actual tax provision, and the amounts obtained by applying the applicable statutory United States federal income tax rate of 35% to income from continuing operations before income taxes for each of the years ended July 31, 2013, 2012, and 2011, respectively (in thousands):

Intangible assets subject to amortization are amortized over their estimated useful lives which are between five and 15 years. Total amortization expense related to intangible assets was approximately $573,000, $548,000 and $1.0 million for the fiscal years ended July 31, 2013, 2012 and 2011, respectively. The estimated amortization expense is projected to be approximately $1.7 million, $1.5 million, $1.3 million, $1.3 million and $1.2 million for fiscal years 2014 through 2018, respectively.

7. LONG-TERM OBLIGATIONS

Working Capital

The Company has a revolving line of credit under an amended and restated credit agreement. At July 31, 2013, the Company had $65.0 million outstanding under that revolving facility and a maximum $41.6 million in additional borrowing capacity, after giving effect to a reduction of $3.4 million for unused letters of credit. The actual amount available under the revolving facility at July 31, 2013 was limited, however, to approximately $18.7 million, because of a loan covenant restriction respecting funded debt to pro-forma earnings before interest, taxes and depreciation. The Company increased the maximum borrowing capacity available under the revolving line in April 2013 in anticipation of the acquisition of the UPC business subsidiaries of OM Group. Management believes that the current credit facility, combined with cash flows from operations, will adequately provide for working capital needs for current operations for the next twelve months.

Long Term Obligations

The Company’s long-term debt and current maturities as of July 31, 2013 and July 31, 2012 consisted of the following (in thousands):

	July 31, 2013		July 31, 2012
Senior Secured Debt:
Note Purchase Agreement, maturing on December 31, 2014, interest rate of 7.43%	$	20,000	$	20,000

Long-term debt, net of current maturities	$	85,000	$	24,000

To finance the acquisition of the electronic chemicals business in December 2007, the Company entered into an amended and restated credit agreement and a note purchase agreement. The amended and restated credit agreement is now with Wells Fargo Bank, National Association, and with Bank of America, N.A. The note purchase agreement is now with The Prudential Insurance Company of America and Pruco Life Insurance Company.

Initially, the amended and restated credit agreement included a revolving loan facility and a term loan facility. The Company amended these facilities several times, most recently in April 2013 and May 2013, to increase the amount that may be borrowed under the revolving loan up to $110.0 million, including an accordion feature that allows for an additional revolving loan increase of up to $25.0 million with approval from the Company’s lenders, and to extend the maturity date of the revolving loan facility to April 30, 2018, with mandatory reduction in revolving loan commitment of $10.0 million each year from September 30, 2014 to September 30, 2017 totaling $40.0 million. The Company recorded $229,000 of financing costs in connection with the amendment of revolving loan facility. The matrix for the calculation of interest payable on the revolving loan facility and the method for the calculation of the fixed charge coverage ratio were also revised.

The revolving loan bears interest at varying rate of LIBOR plus a margin based on funded debt to earnings before interest, taxes, depreciation and amortization (“EBITDA”), as described in the table.

Ratio of Funded Debt to EBITDA	Margin
Equal to or greater than 2.5 to 1.0		2.25	%
Equal to or greater than 2.0 to 1.0, but less than 2.5 to 1.0		2.00	%
Equal to or greater than 1.5 to 1.0, but less than 2.0 to 1.0		1.75	%
Less than 1.5 to 1.0		1.50	%

The Company also incurs an unused commitment fee on the unused amount of commitments under revolving loan facility of 0.35% or 0.25% based on ratio of funded debt to EBITDA. Advances under the revolving loan incurred interest at 1.69% and 2.2% as of July 31, 2013 and July 31, 2012, respectively. The amount outstanding on the revolving loan facility was $65.0 million at July 31, 2013.

During the first quarter of fiscal year 2012, the Company repaid the outstanding balance of the term loan with borrowings on the revolving loan and in a November 2011 amendment, that aspect of the facility was deleted.

44

The note purchase agreement is for $20.0 million. Advances under the note purchase agreement mature December 31, 2014, and bears interest at 7.43% per annum. Principal is payable at maturity. At July 31, 2013, $20.0 million was outstanding under the note purchase agreement.

Loans under the amended and restated credit facility and the note purchase agreement are secured by the Company’s assets, including stock in subsidiaries, inventory, accounts receivable, equipment, intangible assets, and real property. The credit facility and the note purchase agreement have restrictive covenants, including that the Company must maintain a fixed charge coverage ratio of 1.5 to 1.0, a ratio of funded debt to EBITDA (as adjusted for extraordinary items, with lender consent) of 3.0 to 1.0 and a current ratio of at least 1.5 to 1.0.

Principal payments due under long-term debt agreements for the fiscal years ended July 31 are as follows (in thousands):

	Total		2014		2015		2016		2017		2018		Thereafter

8. COMMITMENTS AND CONTINGENCIES

Contractual Obligations — The Company has non-cancelable operating leases for its office and warehouse facilities and certain transportation equipment and purchase obligations. Our obligations to make future payments under certain contractual obligations as of July 31, 2013 are summarized in the following table (in thousands):

	Total		2014		2015		2016		2017		2018		Thereafter
Operating leases	$	11,942	$	3,748	$	1,775	$	1,493	$	1,119	$	752	$	3,055

Total	$	201,450	$	74,031	$	50,097	$	42,244	$	29,156	$	2,867	$	3,055

(1) Consists primarily of raw materials purchase contracts. These are typically not fixed price arrangements. The prices are based on the prevailing market prices.

Rent expense relating to the operating leases was approximately $2.7 million, $2.3 million and $2.0 million in fiscal years 2013, 2012 and 2011, respectively.

Environmental — The Company’s operations are subject to extensive federal, state and local laws, regulations and ordinances in the United States and abroad relating to the generation, storage, handling, emission, transportation and discharge of certain materials, substances and waste into the environment, and various other health and safety matters. Governmental authorities have the power to enforce compliance with their regulations, and violators may be subject to fines, injunctions or both. The Company must devote substantial financial resources to ensure compliance, and it believes that it is in substantial compliance with all the applicable laws and regulations.

Certain licenses, permits and product registrations are required for the Company’s products and operations in the United States, Mexico and other countries in which it does business. The licenses, permits and product registrations are subject to revocation, modification and renewal by governmental authorities. In the United States in particular, producers and distributors of chemicals such as penta and creosote are subject to registration and notification requirements under federal law (including under the Federal Insecticide Fungicide and Rodenticide Act (“FIFRA”), and comparable state law) in order to sell those products in the United States. Compliance with these requirements has had, and in the future will continue to have, a material effect on our business, financial condition and results of operations.

The Company incurred expenses in connection with FIFRA research and testing programs of approximately $522,000, $802,000, and $760,000 in fiscal year 2013, 2012 and 2011, respectively. These costs are included in selling, general, and administrative expenses.

Litigation and Other Contingencies — The Company is subject to contingencies, including litigation relating to environmental laws and regulations, commercial disputes and other matters. Certain of these contingencies are discussed below. The ultimate resolution of these contingencies is subject to significant uncertainty, and should the Company fail to prevail in any of them or should several of them be resolved against the Company in the same reporting period, these matters could, individually or in the aggregate, be material to the consolidated financial statements. The ultimate outcome of these matters, however, cannot be determined at this time, nor can the amount of any potential loss be reasonably estimated, and as a result except where indicated no amounts have been recorded in the Company’s consolidated financial statements.

The Company records legal costs associated with loss contingencies as expenses in the period in which they are incurred.

A lawsuit was filed against the Company’s wholly-owned subsidiary, KMG de Mexico, relating to the title to the land on which its facility in Matamoros is located. The plaintiffs claim that their title to the land is superior to the person from whom our subsidiary bought the land. The plaintiffs are seeking to have our subsidiary’s purchase overturned, and to recover the land and certain improvements or their value. The lawsuit was initially filed in 1998 in Matamoros, Mexico under Adolfo Cazares Rosas, et al vs. KMG de Mexico and Guillermo Villarreal. In January 2008, the case was sent by the appeals court back to the lower court to obtain additional factual information, and on April 20, 2009 the plaintiffs were required to re-file the case in the First Civil Court in Matamoros, Tamaulipas, Mexico as Adolfo Cazares, Luis Escudero and Juan Cue vs. KMG de Mexico and Guillermo Villarreal. In June 2011 the lower court ruled against KMG de Mexico, and held that the plaintiffs had superior title to the land, but that verdict was overturned on appeal in May 2012, and the case will be returned to the trial court for further action. The Company intends to continue to vigorously defend KMG de Mexico.

The Company’s subsidiary in Italy has filed suit with the Provincial Tax Court in Milan, Italy to contest assessments by the taxing authority in Italy pertaining to the three year period ended July 31, 2011. In the aggregate, the amount of the assessments, including interest and penalties, is €1.7 million. If all the adjustments are sustained, the additional liability for the years 2009 through 2011 would total approximately $2.3 million, including interest and penalties through July 31, 2013 (at an exchange rate of 1.328 $/€). The Company recorded a liability for an uncertain tax position for items in the amount of $437,000. See Note 5. The Company intends to vigorously pursue its position before the court, but the ultimate outcome of this litigation is subject to uncertainty.

In May 2013 the taxing authority in Italy assessed additional registration tax against the Company’s subsidiary in Italy based on an increased valuation of assets purchased from Air Products and Chemicals, Inc. in December 2007. The amount of the assessment, including interest and penalties through July 31, 2013, is €773,000 (or approximately $1.0 million, at an exchange rate of 1.328 $/€). The Company is negotiating the matter with the taxing authority, and the Company intends to vigorously defend its tax position. The ultimate outcome of this assessment is subject to uncertainty.

The Company and OM Group dispute the proper calculation of the post-closing, working capital adjustment to the purchase price for the UPC subsidiaries. Each company asserts that the other owes it approximately $700,000. The parties are continuing to negotiate to resolve the dispute, but no resolution has yet been reached.

The Company is subject to federal, state, local and foreign laws and regulations and potential liabilities relating to the protection of the environment and human health and safety including, among other things, the cleanup of contaminated sites, the treatment, storage and disposal of wastes, the emission of substances into the air or waterways, and various health and safety matters. The Company expects to incur substantial costs for ongoing compliance with such laws and regulations. The Company may also face governmental or third-party claims, or otherwise incur costs, relating to cleanup of, or for injuries resulting from, contamination at sites associated with past and present operations. The Company accrues for environmental liabilities when a determination can be made that they are probable and reasonably estimable.

9. EMPLOYEE BENEFIT PLANS

The Company has a defined contribution 401(k) plan in which all regular U.S. employees are eligible to participate. The Company makes matching contributions under this plan of up to 4% of a participant’s compensation up to the annual regulated maximum amounts. The first 3% of the employee contribution is matched at 100%. The next 2% of the employee contribution is matched at 50%. Company contributions to the plan totaled approximately $457,000, $420,000 and $393,000 in fiscal years 2013, 2012 and 2011, respectively.

The locations in the United Kingdom and Singapore, acquired as part of the UPC acquisition from OM Group, make contributions to retirement plans that function as a defined contribution retirement plans. The Company’s contributions to those plans was not significant in fiscal year 2013.

As of July 31, 2013, the Company’s other long-term liabilities included approximately $960,000 related to benefit obligations in connection with one of its foreign subsidiaries included in the acquisition of the UPC business. This payable is an unfunded benefit obligation of the Company.

The Company has an employee benefit arrangement for one of its former U.S. employees. As of July 31, 2013 and 2012, the associated liability was approximately $617,000 and $664,000, respectively. The amount payable is a general obligation of the Company. Benefit payments under this arrangement, which were started in April 2013, will be paid for 10 years.

10. EARNINGS PER SHARE

Basic earnings per share have been computed by dividing net income by the weighted average shares outstanding. Diluted earnings per share have been computed by dividing net income by the weighted average shares outstanding plus potentially dilutive common shares. The following table presents information necessary to calculate basic and diluted earnings per share for periods indicated:

	Year Ended
	2013			2012			2011
	(Amounts in thousands, except per share data)
Income from continuing operations	$	9,486		$	14,315		$	9,418
Income/(loss) from discontinued operations		(138	)		(490	)		311
Net income	$	9,348		$	13,825		$	9,729
Weighted average shares outstanding — basic		11,487			11,363			11,309
Dilutive effect of options/warrants and stock awards		91			165			180
Weighted average shares outstanding — diluted		11,578			11,528			11,489
Basic earnings per share
Basic earnings per share from continuing operations	$	0.82		$	1.26		$	0.83
Basic earnings per share on income/(loss) from discontinued operations		(0.01	)		(0.04	)		0.03
Basic earnings per share	$	0.81		$	1.22		$	0.86
Diluted earnings per share
Diluted earnings per share from continuing operations	$	0.82		$	1.24		$	0.82
Diluted earnings per share on income/(loss) from discontinued operations		(0.01	)		(0.04	)		0.03
Diluted earnings per share	$	0.81		$	1.20		$	0.85

Outstanding stock-based awards are not included in the computation of diluted earnings per share under the treasury stock method, if including them would be anti-dilutive. There was an average of 6,222 shares and 4,972 shares for the fiscal year ended 2013 and 2012, respectively, and less than one thousand shares of potentially dilutive securities for the fiscal year ended 2011, not included in the computation of diluted earnings per share.

11. STOCK-BASED COMPENSATION

Stock-Based Incentive Plans

The Company adopted a 2009 Long-Term Incentive Plan (“2009 LTI Plan”) in October 2009, and it was approved by the shareholders at the annual meeting in December 2009. The Company adopted a 2004 Long-Term Incentive Plan (“2004 LTI Plan”) in October 2004, and it was approved by the shareholders at the annual meeting in November 2005 (the 2009 LTI Plan and the 2004 LTI Plan are referred to collectively as the “LTI Plans”). The Company adopted the 1996 Stock Option Plan (the “1996 Stock Plan”) in October, 1996, and it was approved by the Company’s shareholders in October, 1996.

The LTI Plans permit the granting of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance awards, dividend equivalent rights, and other awards. They are administered by the Board of Directors or a committee appointed by the Board of Directors. The Board has designated the Compensation Committee as the administrator of the LTI Plans. Subject to the terms of the LTI Plans, the committee has the sole discretion to select the persons eligible to receive awards, the type and amount of incentives to be awarded, and the terms and conditions of awards. The committee also has the authority to interpret the LTI Plans, and establish and amend regulations necessary or appropriate for their administration. Any employee of the Company or a subsidiary of the Company or a director of the Company whose judgment, initiative, and efforts contributed or may be expected to contribute to the successful performance of the Company is eligible to participate. The maximum number of shares of the Company’s common stock that may be delivered pursuant to awards granted is 750,000 shares under the 2009 Long-Term Incentive Plan and 375,000 shares under the 2004 Long-Term Incentive Plan. Under the 2009 Long-Term Plan no executive officer may receive in any calendar year stock options or stock appreciation rights, or awards that are subject to the attainment of performance goals relating to more than 200,000 shares of common stock. Under the 2004 Long-Term Plan no executive officer may receive in any calendar year stock options or stock appreciation rights relating to more than 250,000 shares of common stock, or awards that are subject to the attainment of performance goals relating to more than 100,000 shares of common stock. At July 31, 2013 there were approximately 502,377 shares and 63,700 shares available for future grants under the 2009 Long-Term Plan and 2004 Long-Term Plan, respectively.

47

The 1996 Stock Plan terminated by expiration of its original term on July 31, 2007. Options previously issued under the plan remain in effect. The 1996 Stock Plan is administered either by the Company’s Board of Directors or by a committee of two or more non-employee directors. The Board designated the Compensation Committee as the administrator of the plan. Options are exercisable during the period specified in each option agreement and in accordance with a vesting schedule designated by the Board of Directors or the committee. Any option agreement may provide that options become immediately exercisable in the event of a change or threatened change in control of the Company and in the event of certain mergers and reorganizations of the Company. Options may be subject to early termination within a designated period following the option holder’s cessation of service with the Company.

Accounting for Stock-Based Compensation

The Company recognized stock-based compensation costs of approximately $446,000, $714,000 and $542,000, respectively, for the fiscal years ended July 31, 2013, 2012 and 2011, and the related tax benefits of $168,000, $266,000 and $209,000, respectively, for the fiscal years ended July 31, 2013, 2012 and 2011. Stock-based compensation costs are recorded as selling, general and administrative expenses in the consolidated statements of income. The Company accounts for stock-based compensation costs at fair value measured on the date of grant of the award using a Black-Scholes option valuation model for stock option awards. Grant date fair value for stock awards is measured using the Company’s closing stock price on the date of grant of the stock awards where the award is based on a specific number of shares. Stock-based compensation costs are recognized as an expense over the requisite service period, generally the vesting period of the award, using the straight-line method.

As of July 31, 2013, there was approximately $196,000 of unrecognized compensation costs that were related to outstanding stock awards expected to be recognized over a weighted-average period of 1.9 years.

In connection with the election of Christopher T. Fraser as the Company’s President and Chief Executive Officer on September 24, 2013, the Company granted Mr. Fraser (i) 50,000 shares of common stock and (ii) time-based restricted stock awards for 30,000 shares of common stock (vesting over five years). The Company also agreed to grant performance-based restricted stock awards for an aggregate of 70,000 shares of common stock in five equal installments beginning in fiscal year 2013. The Company will record an expense of approximately $1.1 million in the first quarter of fiscal year 2014 for the grant date fair value of the 50,000 shares of common stock.

A summary of activity for stock option and stock-awards is presented below.

Performance Shares

The Company grants performance based shares to certain executives and employees consisting of Series 1 and Series 2 awards. Stock-based compensation for the awards is recognized on a straight-line basis over the requisite service period beginning on the date of grant through the end of the measurement period based on the number of shares expected to vest at the end of the measurement period. The expected percent of vesting is determined using certain performance measures described below and is re-evaluated at the end of each reporting period through the end of the measurement period.

At August 1, 2012 there were 227,609 non-vested performance shares outstanding. During fiscal year 2013 there were 141,059 Series 1 shares granted and there were 150,947 shares forfeited. These shares represented the maximum award subject to certain performance measures. There were 7,556 performance shares vested during fiscal year 2013. At July 31, 2013, there were 154,758 non-vested performance shares outstanding reflecting the maximum number of shares issuable under outstanding awards.

The fair value of the fiscal year 2013 award was measured on the grant dates on December 4, 2012 using the Company’s closing stock price of $18.75. Stock-based compensation on the award is recognized on a straight-line basis over the requisite service period beginning on the date of grant through the end of the measurement period ending on July 31, 2015, based on the number of shares expected to vest at the end of the measurement period.

A summary of the performance based stock awards granted to certain executives as Series 1 awards in fiscal year 2013 and Series 1 and Series 2 awards in fiscal years 2012 and 2011 is detailed below.

For the other performance share grants identified in the above table, the information set forth is the expected vesting percentage and the shares projected to vest.

49

Series 1: Vesting for the Series 1 awards is subject to a performance requirement composed of certain revenue growth objectives and average annual return on invested capital or equity objectives measured across a three-year period. For the fiscal year 2013 and 2012 awards, the expected percentage of vesting is based on performance through July 31, 2013 and reflects the percentage of shares projected to vest for the respective awards at the end of their measurement periods. For the Series 1 award for fiscal year 2011, the actual vesting was determined to be 20% at the end of the measurement period. Performance shares that have vested are normally issued within 75 days of the end of the fiscal year.

Series 2: Vesting for the Series 2 awards is subject to performance requirements pertaining to the growth rate in the Company’s basic earnings per share over a three-year period. For the fiscal year 2012 awards the expected percentage of vesting is based on performance through July 31, 2013 and reflects the percentage of shares projected to vest for the respective awards at the end of their measurement periods. For the Series 2 award for fiscal year 2011, the actual vesting was determined to be zero at the end of the measurement period. Performance shares that have vested are normally issued within 75 days of the end of the fiscal year.

The weighted-average grant-date fair value of performance share awards forfeited during the fiscal year 2013 was $16.36. The weighted-average grant-date fair value of performance share awards outstanding at August 1, 2012 and July 31, 2013 was $15.10 and $17.66, respectively.

The escrowed funds are to be released to the Company once the EPA has finally accepted the studies, the buyer has voluntarily canceled the products, or after five years. The escrowed funds are to be released to the buyer if the EPA cancels the products to which the studies pertain before the funds are distributed to the Company.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

The term “disclosure controls and procedures” is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934. This term refers to the controls and procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the Securities and Exchange Commission. Our management, including our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this annual report. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of the end of the period covered by this annual report.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluations of effectiveness to future periods is subject to the risk that controls may become inadequate in the future period because of changes in conditions, in the degree of compliance with the policies, or because procedures may deteriorate.

Under the supervision and with the participation of our management, including our principal executive and principal financial officers, we conducted an assessment as of July 31, 2013 of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the “COSO Framework”). Based on this assessment, management concluded that its internal control over financial reporting was effective as of July 31, 2013. In conducting the review of the effectiveness of the internal controls over financial reporting as of July 31, 2013, our management, as permitted by the guidance issued by the SEC, did not conduct a review of the effectiveness of internal control of the subsidiaries acquired from OM Group on May 31, 2013.

Management’s assertion about the effectiveness of our internal control over financial reporting as of July 31, 2013, has been audited by KPMG LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Changes in Internal Control over Financial Reporting

There were no changes to our internal control over financial reporting identified in conjunction with our management’s evaluation of such control that occurred during our fiscal quarter ended July 31, 2013 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Summary Of Significant Accounting Policies (Policies)

12 Months Ended

Jul. 31, 2013

General

General — KMG Chemicals, Inc. (the “Company”) is involved principally in the manufacture, formulation and distribution of specialty chemicals in carefully focused markets through its two wholly-owned subsidiaries, KMG Electronic Chemicals, Inc. (“KMG EC”) and KMG-Bernuth, Inc. (“KMG Bernuth”).

In its electronic chemicals business, the Company sells high purity wet process chemicals to the semiconductor industry, and in the wood treating chemicals business the Company sells two industrial wood treating chemicals, pentachlorophenol (“penta”) and creosote. The Company operates its electronic chemicals business through KMG EC in North America and through KMG Italia, S.r.l. (“KMG Italia”) and KMG Electronic Chemicals Holdings S.a.r.l (“KMG Lux”) (and its subsidiaries) in Europe and elsewhere. That business has facilities in the United States, the United Kingdom, France, Italy and Singapore. In the wood treating business the Company manufactures penta at its plant in Matamoros, Mexico through KMG de Mexico (“KMEX”), a Mexican corporation which is a wholly-owned subsidiary of KMG Bernuth. The Company sells its wood treating chemicals in the United States, Mexico and Canada. The electronic chemicals and wood treating businesses constitute two reportable segments that the Company considers of equal importance. See Note 13.

Principles of Consolidation

Principles of Consolidation — The consolidated financial statements include the accounts of KMG Chemicals, Inc. and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“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 these estimates.

Reclassifications

Reclassifications — Certain reclassifications of prior year amounts have been made to conform to current year presentation.

Cash and Cash Equivalents

Cash and Cash Equivalents — The Company considers all investments with original maturities of three months or less when purchased to be cash equivalents. The Company reduces cash balances when checks are disbursed. Due to the time delay in checks clearing the banks, the Company reports a negative balance in its cash disbursement accounts as a current liability which is reflected as book overdraft in the consolidated balance sheets. The Company did not have a negative cash balance as of July 31, 2013.

Restricted Cash

Restricted Cash — Restricted cash includes cash balances which are legally or contractually restricted to use. The Company’s restricted cash as of July 31, 2013 and 2012 includes proceeds that were placed in escrow in connection with the sale of the animal health business. See Note 12.

Fair Value of Financial Instruments

Fair Value of Financial Instruments — The carrying value of financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable approximate fair value because of the relatively short maturity of these instruments. The fair value of the Company’s debt at July 31, 2013 and 2012 approximated its carrying value since the debt obligations bear interest at a rate consistent with market rates.

Accounts Receivable

Accounts Receivable — The Company’s trade accounts receivable are primarily from wood-treating customers and from electronic chemical customers worldwide. The Company extends credit based on an evaluation of the customer’s financial condition, generally without requiring collateral. Exposure to losses on receivables is dependent on each customer’s financial condition. At July 31, 2013 there were two customers that represented approximately 12% and 14%, respectively of the Company’s accounts receivable, and at July 31, 2012 there were two customers that represented approximately 12% and 17%, respectively, of the Company’s accounts receivable.

The Company records an allowance for doubtful accounts to reduce accounts receivable when the Company believes an account may not be collected. A provision for bad debt expense is recorded to selling, general and administrative expenses. The amount of bad debt expense recorded each period and the resulting adequacy of the allowance at the end of each period are determined using a customer-by-customer analyses of accounts receivable balances each period and our assessment of future bad debt exposure. Historically, write offs of accounts receivable balances have been insignificant. The allowance was $224,000 and $16,000 at July 31, 2013 and 2012, respectively.

Inventories

Inventories — Inventories are valued at the lower of cost or market. For certain products, cost is generally determined using the first-in, first-out (“FIFO”) method. For certain other products the Company utilizes a weighted-average cost. The Company records inventory obsolescence as a reduction in its inventory when considered unsellable.

Property, Plant, and Equipment

Property, Plant, and Equipment — Property, plant, and equipment are stated at cost less accumulated depreciation and amortization. Major renewals and betterments are capitalized. Repairs and maintenance costs are expensed as incurred.

Depreciation for equipment commences once placed in service, and depreciation for buildings and leasehold improvements commences once they are ready for their intended use. Depreciable life is determined through economic analysis. Depreciation for financial statement purposes is provided on the straight-line method.

The estimated useful lives of classes of assets are as follows:

Asset Class	Life (Years)
Building	15 to 30
Plant	10 to 18
Equipment	3 to 15
Leasehold improvements	remaining life of the lease

Depreciation expense was approximately $7.7 million, $6.5 million and $6.3 million in fiscal years 2013, 2012 and 2011, respectively.

Intangible Assets

Intangible Assets — Identifiable intangible assets with a defined life are amortized using a straight-line or accelerated method over the useful lives of the assets. Identifiable intangible assets of an indefinite life are not amortized. These assets are required to be tested for impairment at least annually. If this review indicates that impairment has occurred, the Company’s carrying value of intangibles will be adjusted to fair value. Based on an assessment of qualitative factors, in accordance with GAAP, it was determined that there were no events or circumstances that would lead the Company to a determination that is more likely than not that the fair value of the applicable assets was less than its carrying value as of July 31, 2013 and 2012. The Company concluded that as a result its indefinite lived intangible assets were not impaired as of July 31, 2013 and 2012. It is the Company’s policy to expense costs as incurred in connection with the renewal or extension of its intangible assets.

Goodwill

Goodwill — The Company has goodwill of $3.8 million and $7.1 million, respectively, associated with its wood treating and electronic chemicals segments. The carrying value of the Company’s goodwill is reviewed at least annually, and if this review indicates that it will not be recoverable the Company’s carrying value of goodwill will be adjusted to fair value. Based on an assessment of qualitative factors it was determined that there were no events or circumstances that would lead the Company to a determination that is more likely than not that the fair value of the applicable reporting unit was less than its carrying value as of July 31, 2013 and 2012. Accordingly, the Company determined that as of July 31, 2013 and 2012, goodwill was not impaired. As a result, there was no change in the carrying value of goodwill as of July 31, 2013 and 2012, respectively, except for an increase in goodwill of $7.1 million in connection with the acquisition of the electronic chemicals business subsidiaries of OM Group, Inc. See Note 2.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets — Long-lived assets, including property, plant and equipment, and intangible assets with defined lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its disposition. The measurement of an impairment loss for long-lived assets, where management expects to hold and use the asset, are based on the asset’s estimated fair value. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value.

Revenue Recognition

Revenue Recognition — The Company’s chemical products are sold in the open market and revenue is recognized when risk of loss and title to the products transfers to customers. In general, risk of loss transfers upon shipment to customers. The Company also recognizes service revenue in connection with technical support services and chemicals delivery and handling at customer facilities. Revenue is recognized as those services are provided.

Cost of Sales

Cost of Sales — Cost of sales includes inbound freight charges, purchasing and receiving costs, depreciation, inspection costs and internal transfer costs. In the case of products manufactured by the Company, direct and indirect manufacturing costs (including depreciation and amortization) and associated plant administrative expenses are included as well as laid-in cost of raw materials consumed in the manufacturing process.

Distribution Expenses

Distribution Expenses — These expenses include outbound freight, depreciation, storage and handling expenses and other miscellaneous costs (including depreciation and amortization) associated with product storage, handling and distribution.

Selling, General and Administrative Expenses

Selling, General and Administrative Expenses — These expenses include selling expenses, corporate headquarters’ expenses, amortization of intangible assets and environmental regulatory support expenses.

Advertising Costs

Advertising Costs — Our policy is to expense advertising costs as they are incurred. Advertising costs were approximately $26,000, $347,000 and $608,000 in fiscal years ended July 31, 2013, 2012 and 2011, respectively. These costs were primarily related to the animal health business which is reported as discontinued operations in the consolidated statements of income. See Note 12.

Shipping and Handling Costs

Shipping and Handling Costs — Shipping and handling costs are included in cost of sales and distribution expenses. Inbound freight charges and internal transfer costs are included in cost of sales. Product storage and handling costs and the cost of distributing products to the Company’s customers are included in distribution expenses.

Income Taxes

Income Taxes — The Company files a consolidated United States federal income tax return, and for financial reporting purposes, provides income taxes for the differences between the financial statement carrying amounts of assets and liabilities and their tax bases in accordance with GAAP. See Note 5.

Earnings Per Share

Earnings Per Share — Basic earnings per common share amounts are calculated using the average number of common shares outstanding during each period. Diluted earnings per share assumes the issuance of restricted stock awards and the exercise of stock options having exercise prices less than the average market price during the period of the common stock, using the treasury stock method.

Foreign Currency Translation

Foreign Currency Translation — The functional currency of the Company’s Mexico operations is the U.S. Dollar. As a result, monetary assets and liabilities for KMEX are re-measured to U.S. dollars at current rates at the balance sheet dates, income statement items are re-measured at the average monthly exchange rates for the dates those items were recognized, and certain assets (including plant and production equipment) are re-measured at historical exchange rates. Foreign currency transaction gains and losses are included in the statement of operations as incurred along with gains and losses from currency re-measurement. These gains and losses were nominal in fiscal years 2013, 2012 and 2011.

The Company’s international operations in the electronic chemicals business are in Europe and Singapore, and use local currencies as the functional currency, including the GB Pound, Euro and Singapore Dollar. The translation adjustment resulting from currency translation of the local currency into the reporting currency (U.S. Dollar) is included as a separate component of stockholders’ equity. The assets and liabilities have been translated from local currencies into U.S. Dollars using exchange rates in effect at the balance sheet dates. Results of operations have been translated using the average exchange rates during the period. Foreign currency translation resulted in a translation adjustment gains of $1.8 million and $2.1 million in fiscal years 2013 and 2011, respectively, and a loss of $3.1 million in fiscal years 2012, each of which are included in accumulated other comprehensive loss in the consolidated balance sheets.

Stock-Based Compensation

Stock-Based Compensation — The Company’s stock-based compensation expense is based on the fair value of the award measured on the date of grant. For stock option awards, the grant date fair value is measured using a Black-Scholes option valuation model. For stock awards, the Company’s stock price on the date of the grant is used to measure grant date fair value. For awards of stock which are based on a fixed monetary value the grant date fair value is based on the monetary value. Stock-based compensation costs are recognized as an expense over the requisite service period of the award using the straight-line method.

Recent Accounting Standards

Recent Accounting Standards

The Company has considered all recently issued accounting standards updates and SEC rules and interpretive releases.

In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a similar Tax Loss, or a Tax Credit Carryforward Exists.” The update was issued to reduce the diversity in presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The update requires an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, with certain exceptions listed in the update. The new presentation requirements are effective for interim and annual periods beginning after December 15, 2013. Since this update only affects presentation of unrecognized tax benefits in financial statements, adoption of this standard is not expected to have a material impact on the Company’s financial statements.

Earnings Per Share

10. EARNINGS PER SHARE

Basic earnings per share have been computed by dividing net income by the weighted average shares outstanding. Diluted earnings per share have been computed by dividing net income by the weighted average shares outstanding plus potentially dilutive common shares. The following table presents information necessary to calculate basic and diluted earnings per share for periods indicated:

	Year Ended
	2013			2012			2011
	(Amounts in thousands, except per share data)
Income from continuing operations	$	9,486		$	14,315		$	9,418
Income/(loss) from discontinued operations		(138	)		(490	)		311
Net income	$	9,348		$	13,825		$	9,729
Weighted average shares outstanding — basic		11,487			11,363			11,309
Dilutive effect of options/warrants and stock awards		91			165			180
Weighted average shares outstanding — diluted		11,578			11,528			11,489
Basic earnings per share
Basic earnings per share from continuing operations	$	0.82		$	1.26		$	0.83
Basic earnings per share on income/(loss) from discontinued operations		(0.01	)		(0.04	)		0.03
Basic earnings per share	$	0.81		$	1.22		$	0.86
Diluted earnings per share

Diluted earnings per share on income/(loss) from discontinued operations		(0.01	)		(0.04	)		0.03
Diluted earnings per share	$	0.81		$	1.20		$	0.85

Outstanding stock-based awards are not included in the computation of diluted earnings per share under the treasury stock method, if including them would be anti-dilutive. There was an average of 6,222 shares and 4,972 shares for the fiscal year ended 2013 and 2012, respectively, and less than one thousand shares of potentially dilutive securities for the fiscal year ended 2011, not included in the computation of diluted earnings per share.

Summary Of Significant Accounting Policies

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

General — KMG Chemicals, Inc. (the “Company”) is involved principally in the manufacture, formulation and distribution of specialty chemicals in carefully focused markets through its two wholly-owned subsidiaries, KMG Electronic Chemicals, Inc. (“KMG EC”) and KMG-Bernuth, Inc. (“KMG Bernuth”).

In its electronic chemicals business, the Company sells high purity wet process chemicals to the semiconductor industry, and in the wood treating chemicals business the Company sells two industrial wood treating chemicals, pentachlorophenol (“penta”) and creosote. The Company operates its electronic chemicals business through KMG EC in North America and through KMG Italia, S.r.l. (“KMG Italia”) and KMG Electronic Chemicals Holdings S.a.r.l (“KMG Lux”) (and its subsidiaries) in Europe and elsewhere. That business has facilities in the United States, the United Kingdom, France, Italy and Singapore. In the wood treating business the Company manufactures penta at its plant in Matamoros, Mexico through KMG de Mexico (“KMEX”), a Mexican corporation which is a wholly-owned subsidiary of KMG Bernuth. The Company sells its wood treating chemicals in the United States, Mexico and Canada. The electronic chemicals and wood treating businesses constitute two reportable segments that the Company considers of equal importance. See Note 13.

Principles of Consolidation — The consolidated financial statements include the accounts of KMG Chemicals, Inc. and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“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 these estimates.

Reclassifications — Certain reclassifications of prior year amounts have been made to conform to current year presentation.

Cash and Cash Equivalents — The Company considers all investments with original maturities of three months or less when purchased to be cash equivalents. The Company reduces cash balances when checks are disbursed. Due to the time delay in checks clearing the banks, the Company reports a negative balance in its cash disbursement accounts as a current liability which is reflected as book overdraft in the consolidated balance sheets. The Company did not have a negative cash balance as of July 31, 2013.

Restricted Cash — Restricted cash includes cash balances which are legally or contractually restricted to use. The Company’s restricted cash as of July 31, 2013 and 2012 includes proceeds that were placed in escrow in connection with the sale of the animal health business. See Note 12.

Fair Value of Financial Instruments — The carrying value of financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable approximate fair value because of the relatively short maturity of these instruments. The fair value of the Company’s debt at July 31, 2013 and 2012 approximated its carrying value since the debt obligations bear interest at a rate consistent with market rates.

Accounts Receivable — The Company’s trade accounts receivable are primarily from wood-treating customers and from electronic chemical customers worldwide. The Company extends credit based on an evaluation of the customer’s financial condition, generally without requiring collateral. Exposure to losses on receivables is dependent on each customer’s financial condition. At July 31, 2013 there were two customers that represented approximately 12% and 14%, respectively of the Company’s accounts receivable, and at July 31, 2012 there were two customers that represented approximately 12% and 17%, respectively, of the Company’s accounts receivable.

The Company records an allowance for doubtful accounts to reduce accounts receivable when the Company believes an account may not be collected. A provision for bad debt expense is recorded to selling, general and administrative expenses. The amount of bad debt expense recorded each period and the resulting adequacy of the allowance at the end of each period are determined using a customer-by-customer analyses of accounts receivable balances each period and our assessment of future bad debt exposure. Historically, write offs of accounts receivable balances have been insignificant. The allowance was $224,000 and $16,000 at July 31, 2013 and 2012, respectively.

Inventories — Inventories are valued at the lower of cost or market. For certain products, cost is generally determined using the first-in, first-out (“FIFO”) method. For certain other products the Company utilizes a weighted-average cost. The Company records inventory obsolescence as a reduction in its inventory when considered unsellable.

Property, Plant, and Equipment — Property, plant, and equipment are stated at cost less accumulated depreciation and amortization. Major renewals and betterments are capitalized. Repairs and maintenance costs are expensed as incurred.

Depreciation for equipment commences once placed in service, and depreciation for buildings and leasehold improvements commences once they are ready for their intended use. Depreciable life is determined through economic analysis. Depreciation for financial statement purposes is provided on the straight-line method.

The estimated useful lives of classes of assets are as follows:

Asset Class	Life (Years)
Building	15 to 30
Plant	10 to 18
Equipment	3 to 15
Leasehold improvements	remaining life of the lease

Depreciation expense was approximately $7.7 million, $6.5 million and $6.3 million in fiscal years 2013, 2012 and 2011, respectively.

Intangible Assets — Identifiable intangible assets with a defined life are amortized using a straight-line or accelerated method over the useful lives of the assets. Identifiable intangible assets of an indefinite life are not amortized. These assets are required to be tested for impairment at least annually. If this review indicates that impairment has occurred, the Company’s carrying value of intangibles will be adjusted to fair value. Based on an assessment of qualitative factors, in accordance with GAAP, it was determined that there were no events or circumstances that would lead the Company to a determination that is more likely than not that the fair value of the applicable assets was less than its carrying value as of July 31, 2013 and 2012. The Company concluded that as a result its indefinite lived intangible assets were not impaired as of July 31, 2013 and 2012. It is the Company’s policy to expense costs as incurred in connection with the renewal or extension of its intangible assets.

Goodwill — The Company has goodwill of $3.8 million and $7.1 million, respectively, associated with its wood treating and electronic chemicals segments. The carrying value of the Company’s goodwill is reviewed at least annually, and if this review indicates that it will not be recoverable the Company’s carrying value of goodwill will be adjusted to fair value. Based on an assessment of qualitative factors it was determined that there were no events or circumstances that would lead the Company to a determination that is more likely than not that the fair value of the applicable reporting unit was less than its carrying value as of July 31, 2013 and 2012. Accordingly, the Company determined that as of July 31, 2013 and 2012, goodwill was not impaired. As a result, there was no change in the carrying value of goodwill as of July 31, 2013 and 2012, respectively, except for an increase in goodwill of $7.1 million in connection with the acquisition of the electronic chemicals business subsidiaries of OM Group, Inc. See Note 2.

Impairment of Long-Lived Assets — Long-lived assets, including property, plant and equipment, and intangible assets with defined lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its disposition. The measurement of an impairment loss for long-lived assets, where management expects to hold and use the asset, are based on the asset’s estimated fair value. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value.

Revenue Recognition — The Company’s chemical products are sold in the open market and revenue is recognized when risk of loss and title to the products transfers to customers. In general, risk of loss transfers upon shipment to customers. The Company also recognizes service revenue in connection with technical support services and chemicals delivery and handling at customer facilities. Revenue is recognized as those services are provided.

Cost of Sales — Cost of sales includes inbound freight charges, purchasing and receiving costs, depreciation, inspection costs and internal transfer costs. In the case of products manufactured by the Company, direct and indirect manufacturing costs (including depreciation and amortization) and associated plant administrative expenses are included as well as laid-in cost of raw materials consumed in the manufacturing process.

Distribution Expenses — These expenses include outbound freight, depreciation, storage and handling expenses and other miscellaneous costs (including depreciation and amortization) associated with product storage, handling and distribution.

Selling, General and Administrative Expenses — These expenses include selling expenses, corporate headquarters’ expenses, amortization of intangible assets and environmental regulatory support expenses.

Advertising Costs — Our policy is to expense advertising costs as they are incurred. Advertising costs were approximately $26,000, $347,000 and $608,000 in fiscal years ended July 31, 2013, 2012 and 2011, respectively. These costs were primarily related to the animal health business which is reported as discontinued operations in the consolidated statements of income. See Note 12.

Shipping and Handling Costs — Shipping and handling costs are included in cost of sales and distribution expenses. Inbound freight charges and internal transfer costs are included in cost of sales. Product storage and handling costs and the cost of distributing products to the Company’s customers are included in distribution expenses.

Income Taxes — The Company files a consolidated United States federal income tax return, and for financial reporting purposes, provides income taxes for the differences between the financial statement carrying amounts of assets and liabilities and their tax bases in accordance with GAAP. See Note 5.

Earnings Per Share — Basic earnings per common share amounts are calculated using the average number of common shares outstanding during each period. Diluted earnings per share assumes the issuance of restricted stock awards and the exercise of stock options having exercise prices less than the average market price during the period of the common stock, using the treasury stock method.

Foreign Currency Translation — The functional currency of the Company’s Mexico operations is the U.S. Dollar. As a result, monetary assets and liabilities for KMEX are re-measured to U.S. dollars at current rates at the balance sheet dates, income statement items are re-measured at the average monthly exchange rates for the dates those items were recognized, and certain assets (including plant and production equipment) are re-measured at historical exchange rates. Foreign currency transaction gains and losses are included in the statement of operations as incurred along with gains and losses from currency re-measurement. These gains and losses were nominal in fiscal years 2013, 2012 and 2011.

The Company’s international operations in the electronic chemicals business are in Europe and Singapore, and use local currencies as the functional currency, including the GB Pound, Euro and Singapore Dollar. The translation adjustment resulting from currency translation of the local currency into the reporting currency (U.S. Dollar) is included as a separate component of stockholders’ equity. The assets and liabilities have been translated from local currencies into U.S. Dollars using exchange rates in effect at the balance sheet dates. Results of operations have been translated using the average exchange rates during the period. Foreign currency translation resulted in a translation adjustment gains of $1.8 million and $2.1 million in fiscal years 2013 and 2011, respectively, and a loss of $3.1 million in fiscal years 2012, each of which are included in accumulated other comprehensive loss in the consolidated balance sheets.

Stock-Based Compensation — The Company’s stock-based compensation expense is based on the fair value of the award measured on the date of grant. For stock option awards, the grant date fair value is measured using a Black-Scholes option valuation model. For stock awards, the Company’s stock price on the date of the grant is used to measure grant date fair value. For awards of stock which are based on a fixed monetary value the grant date fair value is based on the monetary value. Stock-based compensation costs are recognized as an expense over the requisite service period of the award using the straight-line method.

Recent Accounting Standards

The Company has considered all recently issued accounting standards updates and SEC rules and interpretive releases.

In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a similar Tax Loss, or a Tax Credit Carryforward Exists.” The update was issued to reduce the diversity in presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The update requires an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, with certain exceptions listed in the update. The new presentation requirements are effective for interim and annual periods beginning after December 15, 2013. Since this update only affects presentation of unrecognized tax benefits in financial statements, adoption of this standard is not expected to have a material impact on the Company’s financial statements.

As of July 31, 2013, the Company has $3.8 million foreign net operating losses carryforwards which do not expire.

The Company records provisions for uncertain tax provisions in accordance with GAAP, which prescribes the minimum recognition threshold that a tax position is required to meet before being recognized in the financial statements. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. The statute of limitations remain open for fiscal year ended July 31, 2010 and forward for United States federal income taxes and fiscal year ended July 31, 2008 and forward for state tax jurisdictions.

The Company’s subsidiary in Italy is currently under examination for the period ended July 31, 2009. Adjustments were proposed by the taxing authority at the end of April 2011 that would result in approximately $1.6 million (including interest and penalties) of additional liability, if all the adjustments are sustained. However, the Company does not expect all of this amount to result in cash payments, as the Company would be able to utilize available net operating losses. The Company has provided additional information and additional documentary evidence in response to the proposed adjustments, and intends to vigorously defend its tax position. The ultimate outcome of this examination is subject to uncertainty, and the Company recorded a liability for its uncertain tax position in Italy in fiscal year 2013 in the amount of $437,000, which includes penalties and interest. These uncertain tax positions primarily relate to transfer pricing.

On January 2, 2013 the American Taxpayer Relief Act was adopted. The law included a retroactive two year extension of the research and development credit from January 1, 2012 through December 31, 2013. A retroactive income tax benefit of approximately $200,000 was recorded by the Company. In July 2013, The Finance Bill 2013 included reductions in the United Kingdom corporation tax rate to 21%, effective April 2014.

Undistributed earnings of the Company’s Mexico subsidiary amount to approximately $5.6 million at July 31, 2013. Those earnings are considered to be permanently reinvested. For the year ended July 31, 2012, the Company implemented an annual dividend policy plan for Mexico up to its current year earnings and profits. It is the Company’s intention to continue to remain permanently invested in Mexico on its prior year cumulative undistributed earnings. Accordingly, no provision for United States income taxes has been provided with respect to these undistributed earnings. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company will be subject to both United States income taxes (subject to an adjustment for foreign tax credits) and potential withholding taxes payable to the foreign country. Determination of the amount of unrecognized deferred United States income tax liability is not practicable due to the complexities associated with its hypothetical calculation.

The following table accounts for the differences between the actual tax provision, and the amounts obtained by applying the applicable statutory United States federal income tax rate of 35% to income from continuing operations before income taxes for each of the years ended July 31, 2013, 2012, and 2011, respectively (in thousands):

Rent expense relating to the operating leases was approximately $2.7 million, $2.3 million and $2.0 million in fiscal years 2013, 2012 and 2011, respectively.

Environmental — The Company’s operations are subject to extensive federal, state and local laws, regulations and ordinances in the United States and abroad relating to the generation, storage, handling, emission, transportation and discharge of certain materials, substances and waste into the environment, and various other health and safety matters. Governmental authorities have the power to enforce compliance with their regulations, and violators may be subject to fines, injunctions or both. The Company must devote substantial financial resources to ensure compliance, and it believes that it is in substantial compliance with all the applicable laws and regulations.

Certain licenses, permits and product registrations are required for the Company’s products and operations in the United States, Mexico and other countries in which it does business. The licenses, permits and product registrations are subject to revocation, modification and renewal by governmental authorities. In the United States in particular, producers and distributors of chemicals such as penta and creosote are subject to registration and notification requirements under federal law (including under the Federal Insecticide Fungicide and Rodenticide Act (“FIFRA”), and comparable state law) in order to sell those products in the United States. Compliance with these requirements has had, and in the future will continue to have, a material effect on our business, financial condition and results of operations.

The Company incurred expenses in connection with FIFRA research and testing programs of approximately $522,000, $802,000, and $760,000 in fiscal year 2013, 2012 and 2011, respectively. These costs are included in selling, general, and administrative expenses.

Litigation and Other Contingencies — The Company is subject to contingencies, including litigation relating to environmental laws and regulations, commercial disputes and other matters. Certain of these contingencies are discussed below. The ultimate resolution of these contingencies is subject to significant uncertainty, and should the Company fail to prevail in any of them or should several of them be resolved against the Company in the same reporting period, these matters could, individually or in the aggregate, be material to the consolidated financial statements. The ultimate outcome of these matters, however, cannot be determined at this time, nor can the amount of any potential loss be reasonably estimated, and as a result except where indicated no amounts have been recorded in the Company’s consolidated financial statements.

The Company records legal costs associated with loss contingencies as expenses in the period in which they are incurred.

A lawsuit was filed against the Company’s wholly-owned subsidiary, KMG de Mexico, relating to the title to the land on which its facility in Matamoros is located. The plaintiffs claim that their title to the land is superior to the person from whom our subsidiary bought the land. The plaintiffs are seeking to have our subsidiary’s purchase overturned, and to recover the land and certain improvements or their value. The lawsuit was initially filed in 1998 in Matamoros, Mexico under Adolfo Cazares Rosas, et al vs. KMG de Mexico and Guillermo Villarreal. In January 2008, the case was sent by the appeals court back to the lower court to obtain additional factual information, and on April 20, 2009 the plaintiffs were required to re-file the case in the First Civil Court in Matamoros, Tamaulipas, Mexico as Adolfo Cazares, Luis Escudero and Juan Cue vs. KMG de Mexico and Guillermo Villarreal. In June 2011 the lower court ruled against KMG de Mexico, and held that the plaintiffs had superior title to the land, but that verdict was overturned on appeal in May 2012, and the case will be returned to the trial court for further action. The Company intends to continue to vigorously defend KMG de Mexico.

The Company’s subsidiary in Italy has filed suit with the Provincial Tax Court in Milan, Italy to contest assessments by the taxing authority in Italy pertaining to the three year period ended July 31, 2011. In the aggregate, the amount of the assessments, including interest and penalties, is €1.7 million. If all the adjustments are sustained, the additional liability for the years 2009 through 2011 would total approximately $2.3 million, including interest and penalties through July 31, 2013 (at an exchange rate of 1.328 $/€). The Company recorded a liability for an uncertain tax position for items in the amount of $437,000. See Note 5. The Company intends to vigorously pursue its position before the court, but the ultimate outcome of this litigation is subject to uncertainty.

In May 2013 the taxing authority in Italy assessed additional registration tax against the Company’s subsidiary in Italy based on an increased valuation of assets purchased from Air Products and Chemicals, Inc. in December 2007. The amount of the assessment, including interest and penalties through July 31, 2013, is €773,000 (or approximately $1.0 million, at an exchange rate of 1.328 $/€). The Company is negotiating the matter with the taxing authority, and the Company intends to vigorously defend its tax position. The ultimate outcome of this assessment is subject to uncertainty.

The Company and OM Group dispute the proper calculation of the post-closing, working capital adjustment to the purchase price for the UPC subsidiaries. Each company asserts that the other owes it approximately $700,000. The parties are continuing to negotiate to resolve the dispute, but no resolution has yet been reached.

The Company is subject to federal, state, local and foreign laws and regulations and potential liabilities relating to the protection of the environment and human health and safety including, among other things, the cleanup of contaminated sites, the treatment, storage and disposal of wastes, the emission of substances into the air or waterways, and various health and safety matters. The Company expects to incur substantial costs for ongoing compliance with such laws and regulations. The Company may also face governmental or third-party claims, or otherwise incur costs, relating to cleanup of, or for injuries resulting from, contamination at sites associated with past and present operations. The Company accrues for environmental liabilities when a determination can be made that they are probable and reasonably estimable.

Stock-Based Compensation

11. STOCK-BASED COMPENSATION

Stock-Based Incentive Plans

The Company adopted a 2009 Long-Term Incentive Plan (“2009 LTI Plan”) in October 2009, and it was approved by the shareholders at the annual meeting in December 2009. The Company adopted a 2004 Long-Term Incentive Plan (“2004 LTI Plan”) in October 2004, and it was approved by the shareholders at the annual meeting in November 2005 (the 2009 LTI Plan and the 2004 LTI Plan are referred to collectively as the “LTI Plans”). The Company adopted the 1996 Stock Option Plan (the “1996 Stock Plan”) in October, 1996, and it was approved by the Company’s shareholders in October, 1996.

The LTI Plans permit the granting of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance awards, dividend equivalent rights, and other awards. They are administered by the Board of Directors or a committee appointed by the Board of Directors. The Board has designated the Compensation Committee as the administrator of the LTI Plans. Subject to the terms of the LTI Plans, the committee has the sole discretion to select the persons eligible to receive awards, the type and amount of incentives to be awarded, and the terms and conditions of awards. The committee also has the authority to interpret the LTI Plans, and establish and amend regulations necessary or appropriate for their administration. Any employee of the Company or a subsidiary of the Company or a director of the Company whose judgment, initiative, and efforts contributed or may be expected to contribute to the successful performance of the Company is eligible to participate. The maximum number of shares of the Company’s common stock that may be delivered pursuant to awards granted is 750,000 shares under the 2009 Long-Term Incentive Plan and 375,000 shares under the 2004 Long-Term Incentive Plan. Under the 2009 Long-Term Plan no executive officer may receive in any calendar year stock options or stock appreciation rights, or awards that are subject to the attainment of performance goals relating to more than 200,000 shares of common stock. Under the 2004 Long-Term Plan no executive officer may receive in any calendar year stock options or stock appreciation rights relating to more than 250,000 shares of common stock, or awards that are subject to the attainment of performance goals relating to more than 100,000 shares of common stock. At July 31, 2013 there were approximately 502,377 shares and 63,700 shares available for future grants under the 2009 Long-Term Plan and 2004 Long-Term Plan, respectively.

The 1996 Stock Plan terminated by expiration of its original term on July 31, 2007. Options previously issued under the plan remain in effect. The 1996 Stock Plan is administered either by the Company’s Board of Directors or by a committee of two or more non-employee directors. The Board designated the Compensation Committee as the administrator of the plan. Options are exercisable during the period specified in each option agreement and in accordance with a vesting schedule designated by the Board of Directors or the committee. Any option agreement may provide that options become immediately exercisable in the event of a change or threatened change in control of the Company and in the event of certain mergers and reorganizations of the Company. Options may be subject to early termination within a designated period following the option holder’s cessation of service with the Company.

Accounting for Stock-Based Compensation

The Company recognized stock-based compensation costs of approximately $446,000, $714,000 and $542,000, respectively, for the fiscal years ended July 31, 2013, 2012 and 2011, and the related tax benefits of $168,000, $266,000 and $209,000, respectively, for the fiscal years ended July 31, 2013, 2012 and 2011. Stock-based compensation costs are recorded as selling, general and administrative expenses in the consolidated statements of income. The Company accounts for stock-based compensation costs at fair value measured on the date of grant of the award using a Black-Scholes option valuation model for stock option awards. Grant date fair value for stock awards is measured using the Company’s closing stock price on the date of grant of the stock awards where the award is based on a specific number of shares. Stock-based compensation costs are recognized as an expense over the requisite service period, generally the vesting period of the award, using the straight-line method.

As of July 31, 2013, there was approximately $196,000 of unrecognized compensation costs that were related to outstanding stock awards expected to be recognized over a weighted-average period of 1.9 years.

In connection with the election of Christopher T. Fraser as the Company’s President and Chief Executive Officer on September 24, 2013, the Company granted Mr. Fraser (i) 50,000 shares of common stock and (ii) time-based restricted stock awards for 30,000 shares of common stock (vesting over five years). The Company also agreed to grant performance-based restricted stock awards for an aggregate of 70,000 shares of common stock in five equal installments beginning in fiscal year 2013. The Company will record an expense of approximately $1.1 million in the first quarter of fiscal year 2014 for the grant date fair value of the 50,000 shares of common stock.

A summary of activity for stock option and stock-awards is presented below.

Stock Options

A summary of option activity associated with employee compensation for the fiscal year ended July 31, 2013 is presented below.

	Shares			Weighted- Average Exercise Price

The following table summarizes information about stock options outstanding at July 31, 2013 that are fully vested (currently exercisable):

	Options Outstanding and Fully Vested		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (years)		Aggregate Intrinsic Value (in thousands) (1)
Total outstanding and fully vested		58,000	$	4.03		6.92	$	1,076

(1) The aggregate intrinsic value is computed based on the closing price of the Company’s stock on July 31, 2013.

No options were granted in fiscal years 2013, 2012 and 2011.

The total intrinsic value of options exercised in fiscal years 2013, 2012 and 2011 was approximately $1.6 million, $629,000 and $546,000, respectively. The total fair value of shares vested was $39,000, $39,000 and $44,000 for the fiscal years ended 2013, 2012, and 2011, respectively.

Performance Shares

The Company grants performance based shares to certain executives and employees consisting of Series 1 and Series 2 awards. Stock-based compensation for the awards is recognized on a straight-line basis over the requisite service period beginning on the date of grant through the end of the measurement period based on the number of shares expected to vest at the end of the measurement period. The expected percent of vesting is determined using certain performance measures described below and is re-evaluated at the end of each reporting period through the end of the measurement period.

At August 1, 2012 there were 227,609 non-vested performance shares outstanding. During fiscal year 2013 there were 141,059 Series 1 shares granted and there were 150,947 shares forfeited. These shares represented the maximum award subject to certain performance measures. There were 7,556 performance shares vested during fiscal year 2013. At July 31, 2013, there were 154,758 non-vested performance shares outstanding reflecting the maximum number of shares issuable under outstanding awards.

The fair value of the fiscal year 2013 award was measured on the grant dates on December 4, 2012 using the Company’s closing stock price of $18.75. Stock-based compensation on the award is recognized on a straight-line basis over the requisite service period beginning on the date of grant through the end of the measurement period ending on July 31, 2015, based on the number of shares expected to vest at the end of the measurement period.

A summary of the performance based stock awards granted to certain executives as Series 1 awards in fiscal year 2013 and Series 1 and Series 2 awards in fiscal years 2012 and 2011 is detailed below.

(1) Series 1 and Series 2 awards to J. Neal Butler were forfeited upon his termination of employment on July 10, 2013 and the table reflects that forfeiture. Shares forfeited included 59,217 shares granted in fiscal year 2013, 30,837 Series 1 and 20,558 Series 2 awards granted in fiscal year 2012, and 24,201 Series 1 and 16,134 Series 2 awards granted in fiscal year 2011.

(2) For performance shares granted in December 2010, the above table represents the actual percentage vesting and shares vested as of the end of the measurement period ended July 31, 2013. For the other performance share grants identified in the above table, the information set forth is the expected vesting percentage and the shares projected to vest.

Series 1: Vesting for the Series 1 awards is subject to a performance requirement composed of certain revenue growth objectives and average annual return on invested capital or equity objectives measured across a three-year period. For the fiscal year 2013 and 2012 awards, the expected percentage of vesting is based on performance through July 31, 2013 and reflects the percentage of shares projected to vest for the respective awards at the end of their measurement periods. For the Series 1 award for fiscal year 2011, the actual vesting was determined to be 20% at the end of the measurement period. Performance shares that have vested are normally issued within 75 days of the end of the fiscal year.

Series 2: Vesting for the Series 2 awards is subject to performance requirements pertaining to the growth rate in the Company’s basic earnings per share over a three-year period. For the fiscal year 2012 awards the expected percentage of vesting is based on performance through July 31, 2013 and reflects the percentage of shares projected to vest for the respective awards at the end of their measurement periods. For the Series 2 award for fiscal year 2011, the actual vesting was determined to be zero at the end of the measurement period. Performance shares that have vested are normally issued within 75 days of the end of the fiscal year.

The weighted-average grant-date fair value of performance share awards forfeited during the fiscal year 2013 was $16.36. The weighted-average grant-date fair value of performance share awards outstanding at August 1, 2012 and July 31, 2013 was $15.10 and $17.66, respectively.

The total fair value of performance shares vested during fiscal years 2013, 2012 and 2011 was approximately $118,000, $297,000, and $63,000, respectively.

Long-Term Obligations

Long-Term Obligations

7. LONG-TERM OBLIGATIONS

Working Capital

The Company has a revolving line of credit under an amended and restated credit agreement. At July 31, 2013, the Company had $65.0 million outstanding under that revolving facility and a maximum $41.6 million in additional borrowing capacity, after giving effect to a reduction of $3.4 million for unused letters of credit. The actual amount available under the revolving facility at July 31, 2013 was limited, however, to approximately $18.7 million, because of a loan covenant restriction respecting funded debt to pro-forma earnings before interest, taxes and depreciation. The Company increased the maximum borrowing capacity available under the revolving line in April 2013 in anticipation of the acquisition of the UPC business subsidiaries of OM Group. Management believes that the current credit facility, combined with cash flows from operations, will adequately provide for working capital needs for current operations for the next twelve months.

Long Term Obligations

The Company’s long-term debt and current maturities as of July 31, 2013 and July 31, 2012 consisted of the following (in thousands):

	July 31, 2013		July 31, 2012
Senior Secured Debt:
Note Purchase Agreement, maturing on December 31, 2014, interest rate of 7.43%	$	20,000	$	20,000
Revolving Loan Facility, maturing on April 30, 2018, variable interest rates based on LIBOR plus 1.50% and 2.0% at July 31, 2013 and 2012, respectively		65,000		4,000
Total debt		85,000		24,000
Current maturities of long-term debt		—		—
Long-term debt, net of current maturities	$	85,000	$	24,000

To finance the acquisition of the electronic chemicals business in December 2007, the Company entered into an amended and restated credit agreement and a note purchase agreement. The amended and restated credit agreement is now with Wells Fargo Bank, National Association, and with Bank of America, N.A. The note purchase agreement is now with The Prudential Insurance Company of America and Pruco Life Insurance Company.

Initially, the amended and restated credit agreement included a revolving loan facility and a term loan facility. The Company amended these facilities several times, most recently in April 2013 and May 2013, to increase the amount that may be borrowed under the revolving loan up to $110.0 million, including an accordion feature that allows for an additional revolving loan increase of up to $25.0 million with approval from the Company’s lenders, and to extend the maturity date of the revolving loan facility to April 30, 2018, with mandatory reduction in revolving loan commitment of $10.0 million each year from September 30, 2014 to September 30, 2017 totaling $40.0 million. The Company recorded $229,000 of financing costs in connection with the amendment of revolving loan facility. The matrix for the calculation of interest payable on the revolving loan facility and the method for the calculation of the fixed charge coverage ratio were also revised.

The revolving loan bears interest at varying rate of LIBOR plus a margin based on funded debt to earnings before interest, taxes, depreciation and amortization (“EBITDA”), as described in the table.

Ratio of Funded Debt to EBITDA	Margin
Equal to or greater than 2.5 to 1.0		2.25	%
Equal to or greater than 2.0 to 1.0, but less than 2.5 to 1.0		2.00	%
Equal to or greater than 1.5 to 1.0, but less than 2.0 to 1.0		1.75	%
Less than 1.5 to 1.0		1.50	%

The Company also incurs an unused commitment fee on the unused amount of commitments under revolving loan facility of 0.35% or 0.25% based on ratio of funded debt to EBITDA. Advances under the revolving loan incurred interest at 1.69% and 2.2% as of July 31, 2013 and July 31, 2012, respectively. The amount outstanding on the revolving loan facility was $65.0 million at July 31, 2013.

During the first quarter of fiscal year 2012, the Company repaid the outstanding balance of the term loan with borrowings on the revolving loan and in a November 2011 amendment, that aspect of the facility was deleted.

The note purchase agreement is for $20.0 million. Advances under the note purchase agreement mature December 31, 2014, and bears interest at 7.43% per annum. Principal is payable at maturity. At July 31, 2013, $20.0 million was outstanding under the note purchase agreement.

Loans under the amended and restated credit facility and the note purchase agreement are secured by the Company’s assets, including stock in subsidiaries, inventory, accounts receivable, equipment, intangible assets, and real property. The credit facility and the note purchase agreement have restrictive covenants, including that the Company must maintain a fixed charge coverage ratio of 1.5 to 1.0, a ratio of funded debt to EBITDA (as adjusted for extraordinary items, with lender consent) of 3.0 to 1.0 and a current ratio of at least 1.5 to 1.0.

Principal payments due under long-term debt agreements for the fiscal years ended July 31 are as follows (in thousands):

	Total		2014		2015		2016		2017		2018		Thereafter
