Operations and equity investment

Information regarding our operations and the companies conducting such operations is set forth below.  Geographic financial information is included in Note 2 to our Consolidated Financial Statements, which is incorporated herein by reference.  

COMPONENT PRODUCTS - COMPX INTERNATIONAL INC.  

Industry overview - Through our majority-owned subsidiary, CompX, we manufacture engineered components that are sold to a variety of industries including recreational transportation (including boats), postal, office and institutional furniture, cabinetry, tool storage, healthcare, gas stations and vending equipment.  We continuously seek to diversify into new markets and identify new applications and features for our products, which we believe provide a greater potential for higher rates of earnings growth as well as diversification of risk.  

Manufacturing, operations and products - CompX’s Security Products business, with one manufacturing facility in South Carolina and one in Illinois shared with the Marine Components business, manufactures mechanical and electronic cabinet locks and other locking mechanisms used in a variety of applications including ignition systems, mailboxes, file cabinets, desk drawers, tool storage cabinets, vending and gaming machines, high security medical cabinetry, electronic circuit panels, storage compartments and gas station security.  We believe that CompX is a North American market leader in the manufacture and sale of cabinet locks and other locking mechanisms.  These products include:

A substantial portion of CompX’s Security Products sales consists of products with specialized adaptations to an individual customer’s specifications, some of which are listed above.  CompX also has a standardized product line suitable for many customers which is offered through a North American distribution network to locksmith and smaller original equipment manufacturer distributors via its STOCK LOCKS^® distribution program.  

- 4 -

CompX’s Marine Components business, with a facility in Wisconsin and a facility shared with the Security Products business in Illinois, manufactures and distributes stainless steel exhaust components, gauges, throttle controls, trim tabs, hardware and accessories primarily for performance and ski/wakeboard boats.  CompX’s specialty marine component products are high precision components designed to operate within tight tolerances in the highly demanding marine environment.  These products include:

The following table sets forth the location, size and business operations for each of CompX’s operating facilities at December 31, 2015:

SP – Security Products business

MC – Marine Components business

We believe all of CompX’s facilities are well maintained and satisfactory for their intended purposes.

Raw materials - The primary raw materials used in CompX’s manufacturing processes are:

These raw materials are purchased from several suppliers, are readily available from numerous sources and accounted for approximately 10% of our total cost of sales for 2015.  Total material costs, including purchased components, represented approximately 48% of our cost of sales in 2015.

CompX occasionally enters into short-term commodity-related raw material supply arrangements to mitigate the impact of future increases in commodity-related raw material costs.  These arrangements generally provide for stated unit prices based upon specified purchase volumes, which help us to stabilize our commodity related raw material costs to a certain extent.  We periodically enter into such arrangements for zinc and brass.  Following a general softening of commodity metal markets during 2015, we expect commodity-related raw material prices to remain relatively stable during 2016; however, these raw materials purchased on the spot market are sometimes subject to unanticipated and sudden price increases.  We generally seek to mitigate the impact of fluctuations in these raw material costs on our margins through improvements in production efficiencies or other operating cost reductions.  In the event we are unable to offset raw material cost increases with other cost reductions, it may be difficult to recover those cost increases through increased product selling prices or raw material surcharges

- 5 -

due to the competitive nature of the markets served by our products.  Consequently, overall operating margins can be affected by commodity-related raw material cost pressures.  Commodity market prices are cyclical, reflecting overall economic trends, specific developments in consuming industries and speculative investor activities.

Patents and trademarks - CompX holds a number of patents relating to component products, certain of which we believe to be important to CompX and its continuing business activity.  Patents generally have a term of 20 years, and CompX’s patents have remaining terms ranging from less than 1 year to 17 years at December 31, 2015.  CompX’s major trademarks and brand names in addition to CompX^® include:  

Sales, marketing and distribution - A majority of CompX’s component sales are sold directly to large OEM customers through our factory-based sales and marketing professionals supported by engineers working in concert with field salespeople and independent manufacturer’s representatives.  We select manufacturer’s representatives based on special skills in certain markets or relationships with current or potential customers.  

In addition to sales to large OEM customers, a substantial portion of CompX’s Security Products sales are made through distributors.  We have a significant North American market share of cabinet lock security product sales as a result of the locksmith distribution channel.  We support our locksmith distributor sales with a line of standardized products used by the largest businesses of the marketplace.  These products are packaged and merchandised for easy availability and handling by distributors and end users.  

In 2015, CompX’s ten largest customers, all Security Products customers, accounted for approximately 48% of our total sales.  United States Postal Service and Harley Davidson accounted for approximately 13% and 12%, respectively, of total sales for the year ended December 31, 2015.  Overall, our customer base is diverse and the loss of any single customer would not in itself have a material adverse effect on our operations.  

Competition - The markets in which CompX participates are highly competitive.  CompX competes primarily on the basis of product design, including space utilization and aesthetic factors, product quality and durability, price, on-time delivery, service and technical support.  CompX focuses its efforts on the middle and high-end businesses of the market, where product design, quality, durability and service are valued by the customer.  The Security Products business competes against a number of U.S. and non-U.S. manufacturers.  The Marine Components business competes with small U.S. manufacturers and is minimally affected by non-U.S. competitors.  

Regulatory and environmental matters - CompX’s operations are subject to federal, state and local  environmental laws and regulations relating to the use, storage, handling, generation, transportation, treatment, emission, discharge, disposal, remediation of and exposure to hazardous and non-hazardous substances, materials and wastes (“Environmental Laws”).  CompX’s operations are also subject to federal, state and local regulations relating to worker health and safety.  We believe that CompX is in substantial compliance with all such laws and regulations.  To date, the costs of maintaining compliance with such laws and regulations have not significantly impacted our results of operations.  We currently do not anticipate any significant costs or expenses relating to such matters; however, it is possible future laws and regulations may require us to incur significant additional expenditures.  

- 6 -

Employees - As of December 31, 2015, CompX employed 512 people, all in the United States.  We believe our labor relations are good at all of our facilities.

CHEMICALS - KRONOS WORLDWIDE, INC.  

Business overview - Kronos is a leading global producer and marketer of value-added titanium dioxide pigments, or TiO₂, a base industrial product used in a wide range of applications.  Kronos, along with its distributors and agents, sells and provides technical services for its products to approximately 4,000 customers in 100 countries with the majority of sales in Europe and North America.  We believe that Kronos has developed considerable expertise and efficiency in the manufacture, sale, shipment and service of its products in domestic and international markets.  

TiO₂ is a white inorganic pigment used in a wide range of products for its exceptional durability and its ability to impart whiteness, brightness and opacity.  TiO₂ is a critical component of everyday applications, such as coatings, plastics and paper, as well as many specialty products such as inks, food and cosmetics.  TiO₂ is widely considered to be superior to alternative white pigments in large part due to its hiding power (or opacity), which is the ability to cover or mask other materials effectively and efficiently.  TiO₂ is designed, marketed and sold based on specific end-use applications.  

TiO₂ is the largest commercially used whitening pigment because it has a high refractive rating, giving it more hiding power than any other commercially produced white pigment.  In addition, TiO₂ has excellent resistance to interaction with other chemicals, good thermal stability and resistance to ultraviolet degradation.  Although there are other white pigments on the market, Kronos believes that there are no effective substitutes for TiO₂ because no other white pigment has the physical properties for achieving comparable opacity and brightness or can be incorporated in as cost-effective a manner.  Pigment extenders such as kaolin clays, calcium carbonate and polymeric opacifiers are used together with TiO₂ in a number of end-use markets.  However, these products are not able to duplicate the opacity performance characteristics of TiO₂ and Kronos believes that these products are unlikely to have a significant impact on the use of TiO₂.  

TiO₂ is considered a “quality-of-life” product.  Demand for TiO₂ has generally been driven by worldwide gross domestic product and has generally increased with rising standards of living in various regions of the world. According to industry estimates, TiO₂ consumption has grown at a compound annual growth rate of approximately 3.0% since 1990.  Per capita consumption of TiO₂ in Western Europe and the United States far exceeds that in other areas of the world, and these regions are expected to continue to be the largest consumers of TiO₂ on a per capita basis.  Kronos believes that Western Europe and North America currently account for approximately 20% and 18% of global TiO₂ consumption, respectively.  Markets for TiO₂ are generally increasing in South America, Eastern Europe, the Asia Pacific region and China and Kronos believes these are significant markets where it expects continued growth as economies in these regions continue to develop and quality-of-life products, including TiO₂, experience greater demand.

Products and end-use markets - Kronos, including its predecessors, has produced and marketed TiO₂ in North America and Europe, its primary markets, for almost 100 years.  We believe that Kronos is the largest producer of TiO₂ in Europe with approximately one-half of its sales volumes attributable to markets in Europe.  The table below shows Kronos’ market share for its significant markets, Europe and North America, for the last three years.

We believe that Kronos is the leading seller of TiO₂ in several countries, including Germany, with an estimated 9% share of worldwide TiO₂ sales volume in 2015.  Overall, Kronos is one of the top five producers of TiO₂ in the world.

Kronos offers its customers a broad portfolio of products that includes over 40 different TiO₂ pigment grades under the Kronos^® trademark, which provide a variety of performance properties to meet customers’ specific requirements.  Kronos’ major customers include domestic and international paint, plastics, decorative laminate and paper manufacturers.  Kronos ships TiO₂ to customers in either a powder or slurry form via rail, truck and/or ocean carrier.  Sales of its core TiO₂ pigments represented approximately 90% of Kronos’ net sales in 2015.  Kronos and its agents and distributors primarily sell its products in three major end-use markets: coatings, plastics and paper.  

The following tables show Kronos’ approximate TiO₂ sales volume by geographic region and end use for the year ended December 31, 2015:

Some of the principal applications for Kronos’ products include the following.

TiO₂ for coatings - Kronos’ TiO₂ is used to provide opacity, durability, tinting strength and brightness in industrial coatings, as well as coatings for commercial and residential interiors and exteriors, automobiles, aircraft, machines, appliances, traffic paint and other special purpose coatings.  The amount of TiO₂ used in coatings varies widely depending on the opacity, color and quality desired.  In general, the higher the opacity requirement of the coating, the greater the TiO₂ content.

TiO₂ for plastics - Kronos produces TiO₂ pigments that improve the optical and physical properties in plastics, including whiteness and opacity.  TiO₂ is used to provide opacity in items such as containers and packaging materials, and vinyl products such as windows, door profiles and siding.  TiO₂ also generally provides hiding power, neutral undertone, brightness and surface durability for housewares, appliances, toys, computer cases and food packages.  TiO₂’s high brightness along with its opacity is used in some engineering plastics to help mask their undesirable natural color.  TiO₂ is also used in masterbatch, which is a concentrate of TiO₂ and other additives and is one of the largest uses for TiO₂ in the plastics end-use market.  In masterbatch, the TiO₂ is dispersed at high concentrations into a plastic resin and is then used by manufacturers of plastic containers, bottles, packaging and agricultural films.

TiO₂ for paper - Kronos’ TiO₂ is used in the production of several types of paper, including laminate (decorative) paper, filled paper and coated paper to provide whiteness, brightness, opacity and color stability.  Although Kronos sells its TiO₂ to all segments of the paper end-use market, its primary focus is on the TiO₂ grades used in paper laminates, where several layers of paper are laminated together using melamine resin under high temperature and pressure.  The top layer of paper contains TiO₂ and plastic resin and is the layer that is printed with decorative patterns.  Paper laminates are used to replace materials such as wood and tile for such applications as counter tops, furniture and wallboard.  TiO₂ is beneficial in these applications because it assists in preventing the material from fading or changing color after prolonged exposure to sunlight and other weathering agents.

TiO₂ for other applications - Kronos produces TiO₂ to improve the opacity and hiding power of printing inks.  TiO₂ allows inks to achieve very high print quality while not interfering with the technical requirements of printing machinery, including low abrasion, high printing speed and high temperatures.  Kronos’ TiO₂ is also used in textile applications where TiO₂ functions as an opacifying and delustering agent.  In man-made fibers such as rayon and polyester, TiO₂ corrects an otherwise undesirable glossy and translucent appearance.  Without the presence of TiO₂, these materials would be unsuitable for use in many textile applications.

Kronos produces high purity sulfate process anatase TiO₂ used to provide opacity, whiteness and brightness in a variety of cosmetic and personal care products, such as skin cream, lipstick, eye shadow and toothpaste.  Kronos’ TiO₂ is also found in food products, such as candy and confectionaries and in pet foods where it is used to obtain uniformity of color and appearance.  In pharmaceuticals, Kronos’ TiO₂ is used commonly as a colorant in pill and

- 8 -

capsule coatings as well as in liquid medicines to provide uniformity of color and appearance.  Kronos^® purified anatase grades meet the applicable requirements of the CTFA (Cosmetics, Toiletries and Fragrances Association), USP and BP (United States Pharmacopoeia and British Pharmacopoeia) and the FDA (United States Food and Drug Administration).  

Kronos’ TiO₂ business is enhanced by the following three complementary businesses, which comprised approximately 10% of its net sales in 2015:

Manufacturing, operations and properties - Kronos produces TiO₂ in two crystalline forms: rutile and anatase.  Rutile TiO₂ is manufactured using both a chloride production process and a sulfate production process, whereas anatase TiO₂ is only produced using a sulfate production process.  Manufacturers of many end-use applications can use either form, especially during periods of tight supply for TiO₂.  The chloride process is the preferred form for use in coatings and plastics, the two largest end-use markets.  Due to environmental factors and customer considerations, the proportion of TiO₂ industry sales represented by chloride process pigments has increased relative to sulfate process pigments, and in 2015, chloride process production facilities represented approximately 49% of industry capacity.  The sulfate process is preferred for use in selected paper products, ceramics, rubber tires, man-made fibers, food products and cosmetics.  Once an intermediate TiO₂ pigment has been produced by either the chloride or sulfate process, it is “finished” into products with specific performance characteristics for particular end-use applications through proprietary processes involving various chemical surface treatments and intensive micronizing (milling).  

Kronos produced 528,000 metric tons of TiO₂ in 2015, up from the 511,000 metric tons produced in 2014.  Kronos’ production amounts include its share of the output produced by its TiO₂ manufacturing joint-venture discussed below in “TiO₂  Manufacturing Joint Venture.”  Kronos’ average production capacity utilization rates were approximately 86%, 92%, and 95% of capacity in 2013, 2014, and 2015 respectively.  Kronos’s production

- 9 -

utilization rates in 2013 were impacted by the previously-reported lockout at its Canadian production facility that began in June 2013.  Kronos operated its Canadian plant at approximately 15% of the plant’s capacity with non-union management employees during the lockout.  Kronos’ production rates in 2014 were also impacted by such lockout, as restart of production at the facility did not begin until February 2014.  Kronos’ production rates in 2014 and in the first quarter of 2015 were also impacted by the implementation of certain productivity-enhancing improvement projects at other facilities as well as necessary improvements to ensure continued compliance with its permit regulations which resulted in longer-than-normal maintenance shutdowns in some instances.

Kronos operates four TiO₂ plants in Europe (one in each of Leverkusen, Germany; Nordenham, Germany; Langerbrugge, Belgium; and Fredrikstad, Norway).  In North America, Kronos has a TiO₂ plant in Varennes, Quebec, Canada and, through the manufacturing joint venture described below in “TiO₂  Manufacturing Joint Venture,” a 50% interest in a TiO₂ plant in Lake Charles, Louisiana.  

Kronos’ production capacity in 2015 was 555,000 metric tons, approximately three-fourths of which was from the chloride production process.  

The following table presents the division of Kronos’ expected 2016 manufacturing capacity by plant location and type of manufacturing process:

Kronos owns the land underlying all of its principle production facilities unless otherwise indicated in the table above.  

Kronos’ production capacity has increased by approximately 12% over the past ten years due to debottlenecking programs, with only moderate capital expenditures.  We believe that Kronos’ annual attainable production capacity for 2016 is approximately 555,000 metric tons and we currently expect Kronos’ production capacity will be at near-capacity levels in 2016.

- 10 -

Kronos also operates two ilmenite mines in Norway pursuant to a governmental concession with an unlimited term.  In addition, Kronos operates a rutile slurry manufacturing plant in Lake Charles, Louisiana, which converts dry pigment manufactured for Kronos at the Lake Charles TiO₂ facility into a slurry form that is then shipped to customers.  

Kronos has various corporate and administrative offices located in the U.S., Germany, Norway, Canada and Belgium and various sales offices located in the U.S., Canada, Belgium, France, the Netherlands and the United Kingdom.  

TiO₂ Manufacturing Joint Venture - Kronos and Tioxide each own a 50% interest in a manufacturing joint venture, Louisiana Pigment Company, L.P. or LPC.  LPC owns and operates a chloride-process TiO₂ facility located in Lake Charles, Louisiana.  Kronos shares production from the plant equally with Huntsman pursuant to separate offtake agreements, unless Kronos and Huntsman otherwise agree (such as in 2015, when Kronos purchased approximately 52% of the production from the plant).  

A supervisory committee directs the business and affairs of LPC, including production and output decisions.  This committee is composed of four members, two of whom Kronos appoints and two of whom Huntsman appoints.  Two general managers manage the operations of the joint venture acting under the direction of the supervisory committee.  Kronos appoints one general manager and Huntsman appoints the other.  

The joint venture is not consolidated in Kronos’ financial statements, because Kronos does not control it.  Kronos accounts for its interest in the joint venture by the equity method.  The joint venture operates on a break-even basis and therefore Kronos does not have any equity in earnings of the joint venture.  Kronos is required to purchase one half of the TiO₂ produced by the joint venture.  Kronos shares all costs and capital expenditures equally with Huntsman with the exception of feedstock (purchased natural rutile ore or slag) and packaging costs for the pigment grades produced.  Kronos’ share of net costs is reported as cost of sales as the TiO₂ is sold.  

Raw materials - The primary raw materials used in chloride process TiO₂ are titanium-containing feedstock (purchased natural rutile ore or slag), chlorine and coke.  Chlorine is available from a number of suppliers, while petroleum coke is available from a limited number of suppliers.  Titanium-containing feedstock suitable for use in the chloride process is available from a limited but increasing number of suppliers principally in Australia, South Africa, Canada, India and the United States.  Kronos purchases chloride process grade slag from Rio Tinto Iron and Titanium Limited under a long-term supply contract that expires at the end of 2018 subject to two-year renewal periods if both parties agree.  Kronos also purchases upgraded slag from Rio Tinto Iron and Titanium Limited under a long-term supply contract that expires at the end of 2019.  Kronos purchases natural rutile ore under contracts primarily from Iluka Resources, Limited and Sierra Rutile Limited, all of which expire in 2016.  In the past Kronos has been, and expects to continue to be successful in obtaining short-term and long-term extensions to these and other existing supply contracts prior to their expiration. Kronos expects the raw materials purchased under these contracts, and contracts that it may enter into, will meet its chloride process feedstock requirements over the next several years.  

The primary raw materials used in sulfate process TiO₂ are titanium-containing feedstock, primarily ilmenite or purchased sulfate grade slag and sulfuric acid.  Sulfuric acid is available from a number of suppliers.  Titanium-containing feedstock suitable for use in the sulfate process is available from a limited number of suppliers principally in Norway, Canada, Australia, India and South Africa.  As one of the few vertically-integrated producers of sulfate process TiO₂, Kronos operates two rock ilmenite mines in Norway, which provided all of the feedstock for its European sulfate process TiO₂ plants in 2015.  Kronos expects ilmenite production from its mines to meet its European sulfate process feedstock requirements for the foreseeable future.  For its Canadian sulfate process plant, Kronos purchases sulfate grade slag primarily from Rio Tinto Fer et Titane Inc., under a supply contract that renews annually, subject to termination upon twelve months written notice.  Kronos expects the raw materials purchased under these contracts, and contracts that it may enter into, to meet its sulfate process feedstock requirements over the next several years.  

Many of Kronos’ raw material contracts contain fixed quantities it is required to purchase, or specify a range of quantities within which Kronos is required to purchase.  The pricing under these agreements is generally negotiated quarterly.  

- 11 -

The following table summarizes Kronos’ raw materials purchased or mined in 2015.  

Sales and marketing - Kronos’ marketing strategy is aimed at developing and maintaining strong customer relationships with new and existing accounts.  Because TiO₂ represents a significant raw material cost for Kronos’ customers, the purchasing decisions are often made by customers’ senior management.  Kronos works to maintain close relationships with the key decision makers, through in-depth and frequent in-person meetings.  Kronos endeavors to extend these commercial and technical relationships to multiple levels within its customers’ organization by using its direct sales force and technical service group to accomplish this objective.  Kronos believes this has helped build customer loyalty to Kronos and strengthen its competitive position.  Close cooperation and strong customer relationships enable Kronos to stay closely attuned to trends in its customers’ businesses.  Where appropriate, Kronos works in conjunction with customers to solve formulation or application problems by modifying specific product properties or developing new pigment grades.  Kronos also focuses its sales and marketing efforts on those geographic and end-use market businesses where Kronos believes it can realize higher selling prices.  This focus includes continuously reviewing and optimizing customer and product portfolios.  

Kronos’ marketing strategy is also aimed at working directly with customers to monitor the success of its products in their end-use applications, evaluate the need for improvements in product and process technology and identify opportunities to develop new product solutions for its customers.  Kronos’ marketing staff closely coordinates with its sales force and technical specialists to ensure that the needs of its customers are met, and to help develop and commercialize new grades where appropriate.  

Kronos sells a majority of its products through its direct sales force operating from six sales offices in Europe and one sales office in North America.  Kronos also utilizes sales agents and distributors who are authorized to sell its products in specific geographic areas.  In Europe, Kronos’ sales efforts are conducted primarily through its direct sales force and its sales agents.  Kronos’ agents do not sell any TiO₂ products other than Kronos^® brand products.  In North America, Kronos’ sales are made primarily through its direct sales force and supported by a network of distributors.  In addition to its direct sales force and sales agents, many of Kronos’ sales agents also act as distributors to service its smaller customers in all regions.  Kronos offers customer and technical service to the customers who purchase its products through distributors as well as to its larger customers serviced by its direct sales force.  

Kronos sells to a diverse customer base with only one customer representing 10% or more of its sales in 2015 (Behr Process Corporation – 10%).  Kronos’ largest ten customers accounted for approximately 34% of sales in 2015.

Neither Kronos’ business as a whole nor any of its principal product groups is seasonal to any significant extent.  However, TiO₂ sales are generally higher in the second and third quarters of the year, due in part to the increase in paint production in the spring to meet demand during the spring and summer painting seasons.  With certain exceptions, Kronos has historically operated its production facilities at near full capacity rates throughout the entire year, which among other things helps to minimize its per-unit production costs.  As a result, Kronos normally will build inventories during the first and fourth quarters of each year, in order to maximize product availability during the higher demand periods normally experienced in the second and third quarters.  

Competition - The TiO₂ industry is highly competitive.  Kronos competes primarily on the basis of price, product quality, technical service and the availability of high performance pigment grades.  Since TiO₂ is not a traded commodity, its pricing is largely a product of negotiation between suppliers and their respective customers.  

- 12 -

Although certain TiO₂ grades are considered specialty pigments, the majority of Kronos’ grades and substantially all of its production are considered commodity pigments with price and availability being the most significant competitive factors along with quality and customer service.  During 2015, Kronos had an estimated 9% share of worldwide TiO₂ sales volume, and based on sales volumes, we believe that Kronos is the leading seller of TiO₂ in several countries, including Germany.  

Kronos’ principal competitors are The Chemours Company, or Chemours (which was spun-off from E.I. du Pont de Nemours & Co. into a separate publicly-traded company in 2015); Millennium Inorganic Chemicals, Inc. (a subsidiary of National Titanium Dioxide Company Ltd.), or Cristal; Huntsman Corporation; and Tronox Incorporated.  The top five TiO₂ producers (i.e. Kronos and its four principal competitors) account for approximately 56% of the world’s production capacity.  Huntsman completed its purchase of the TiO₂ business of Sachtleben Chemie GmbH in 2014, and has also announced its intent to exit the TiO₂ business by December 31, 2016.  In February 2015, Huntsman announced a plan to reduce its TiO₂ capacity by approximately 100,000 metric tons at one of its European sulfate process facilities.  In August 2015, Chemours announced plans to close its plant in Delaware and shut down a production line at its facility in Tennessee, reducing its overall capacity by approximately 150,000 metric tons.  

The following chart shows Kronos’ estimate of worldwide production capacity in 2015:

Chemours has over one-half of total North American TiO₂ production capacity and is Kronos’ principal North American competitor.

Over the past ten years, Kronos and its competitors have increased industry capacity through debottlenecking projects, which in part compensated for the shutdown of various TiO₂ plants in France, the United States, the United Kingdom and China. Chemours has announced the scheduled production start-up of a 200,000 metric ton line at its plant in Mexico in mid-2016.  Although overall industry demand is expected to be generally higher in 2016 as compared to 2015 as a result of improving worldwide economic conditions, Kronos does not expect any other significant efforts will be undertaken by it or its principal competitors to further increase capacity for the foreseeable future, other than through debottlenecking projects.  If actual developments differ from its expectations, the TiO₂ industry’s performance and that of Kronos could be unfavorably affected.

The TiO₂ industry is characterized by high barriers to entry consisting of high capital costs, proprietary technology and significant lead times (typically three to five years in our experience) required to construct new facilities or to expand existing capacity. Kronos believes it is unlikely any new TiO₂ plants will be constructed in Europe or North America in the foreseeable future.  

Research and development - Kronos employs scientists, chemists, process engineers and technicians who are engaged in research and development, process technology and quality assurance activities in Leverkusen, Germany.  These individuals have the responsibility for improving Kronos’ chloride and sulfate production processes, improving product quality and strengthening Kronos’ competitive position by developing new applications.  Kronos’ expenditures for these activities were approximately $18 million in 2013, $19 million in 2014 and $16 million in 2015.  Kronos expects to spend $14 million on research and development in 2016.  

Kronos continually seeks to improve the quality of its grades and has been successful at developing new grades for existing and new applications to meet the needs of its customers and increase product life cycles.  Since 2010, Kronos has added seven new grades for pigments and other applications.

Patents, trademarks, trade secrets and other intellectual property rights - Kronos has a comprehensive intellectual property protection strategy that includes obtaining, maintaining and enforcing its patents, primarily in the United States, Canada and Europe.  Kronos also protects its trademark and trade secret rights and has entered into license agreements with third parties concerning various intellectual property matters.  Kronos has also from time to time been involved in disputes over intellectual property.  

Patents - Kronos has obtained patents and has numerous patent applications pending that cover its products and the technology used in the manufacture of its products.  Kronos’ patent strategy is important to Kronos and its continuing business activities.  In addition to maintaining its patent portfolio, Kronos seeks patent protection for its technical developments, principally in the United States, Canada and Europe.  U.S. patents are generally in effect for 20 years from the date of filing.  Kronos’ U.S. patent portfolio includes patents having remaining terms ranging from one year to 19 years.  

Trademarks and trade secrets - Kronos’ trademarks, including Kronos^®, are covered by issued and or pending registrations, including in Canada and the United States.  Kronos protects the trademarks that it uses in connection with the products it manufactures and sells and has developed goodwill in connection with the long-term use of its trademarks.  Kronos conducts research activities in secret and it protects the confidentiality of its trade secrets through reasonable measures, including confidentiality agreements and security procedures including data security.  Kronos relies upon unpatented proprietary knowledge and continuing technological innovation and other trade secrets to develop and maintain its competitive position.  Kronos’ proprietary chloride production process is an important part of its technology and its business could be harmed if Kronos fails to maintain confidentiality of its trade secrets used in this technology.  

Employees - As of December 31, 2015, Kronos employed the following number of people:

Certain employees at each of Kronos’ production facilities are organized by labor unions.  In Europe, Kronos’ union employees are covered by master collective bargaining agreements for the chemical industry that are generally renewed annually.  In Canada, Kronos’ union employees are covered by a collective bargaining agreement that expires in June 2018.  At December 31, 2015, approximately 87% of Kronos’ worldwide workforce is organized under collective bargaining agreements.  It is possible that there could be future work stoppages or other labor disruptions that could materially and adversely affect Kronos’ business, results of operations, financial position or liquidity.  

Regulatory and environmental matters - Kronos’ operations and properties are governed by various environmental laws and regulations, which are complex, change frequently and have tended to become stricter over time.  These environmental laws govern, among other things, the generation, storage, handling, use and transportation of hazardous materials; the emission and discharge of hazardous materials into the ground, air or water; and the health and safety of employees.  Certain of Kronos’ operations are, or have been, engaged in the generation, storage, handling, manufacture or use of substances or compounds that may be considered toxic or hazardous within the meaning of applicable environmental laws and regulations.  As with other companies engaged in similar businesses, certain of Kronos’ past and current operations and products have the potential to cause environmental or other damage.  Kronos has implemented and continues to implement various policies and programs in an effort to minimize these risks.  Kronos’ policy is to comply with applicable environmental laws and regulations at all of its facilities and to strive to improve environmental performance.  It is possible that future developments, such as stricter requirements in environmental laws and enforcement policies, could adversely affect Kronos’ operations, including production, handling, use, storage, transportation, sale or disposal of hazardous or toxic substances or require Kronos to make capital and other expenditures to comply, and could adversely affect its consolidated financial position and results of operations or liquidity.  

- 14 -

Kronos’ U.S. manufacturing operations are governed by federal, state and local environmental and worker health and safety laws and regulations.  These include the Resource Conservation and Recovery Act, or RCRA, the Occupational Safety and Health Act, the Clean Air Act, the Clean Water Act, the Safe Drinking Water Act, the Toxic Substances Control Act and the Comprehensive Environmental Response, Compensation and Liability Act, as amended by the Superfund Amendments and Reauthorization Act, or CERCLA, as well as the state counterparts of these statutes.  Some of these laws hold current or previous owners or operators of real property liable for the costs of cleaning up contamination, even if these owners or operators did not know of, and were not responsible for, such contamination.  These laws also assess liability on any person who arranges for the disposal or treatment of hazardous substances, regardless of whether the affected site is owned or operated by such person.  Although Kronos has not incurred and does not currently anticipate any material liabilities in connection with such environmental laws, it may be required to make expenditures for environmental remediation in the future.  

While the laws regulating operations of industrial facilities in Europe vary from country to country, a common regulatory framework is provided by the European Union, or the EU.  Germany and Belgium are members of the EU and follow its initiatives.  Norway is not a member but generally patterns its environmental regulatory actions after the EU.  

At Kronos’ sulfate plant facilities in Germany, it recycles spent sulfuric acid either through contracts with third parties or at its own facilities.  In addition, at Kronos’ German locations it has a contract with a third party to treat certain sulfate-process effluents.  At its Norwegian plant, Kronos ships spent acid to a third party location where it is used as a neutralization agent.  These contracts may be terminated by either party after giving three or four years advance notice, depending on the contract.  

From time to time, Kronos’ facilities may be subject to environmental regulatory enforcement under U.S.  and non-U.S. statutes.  Typically Kronos establishes compliance programs to resolve these matters.  Occasionally, Kronos may pay penalties.  To date such penalties have not involved amounts having a material adverse effect on Kronos’ consolidated financial position, results of operations or liquidity.  We believe that all of Kronos’ facilities are in substantial compliance with applicable environmental laws.  

Kronos’ capital expenditures related to ongoing environmental compliance, protection and improvement programs, including capital expenditures which are primarily focused on increased operating efficiency but also result in improved environmental protection such as lower emissions from its manufacturing facilities, were $6.9 million in 2015 and are currently expected to be approximately $9 million in 2016.

Other

In addition to our 87% ownership of CompX and our 30% ownership of Kronos at December 31, 2015, we also own 100% of EWI RE, Inc., an insurance brokerage and risk management services company.  We also hold certain marketable securities and other investments.  See Notes 5 and 15 to our Consolidated Financial Statements.  

Regulatory and environmental matters - We discuss regulatory and environmental matters in the respective business sections contained elsewhere herein and in Item 3 - “Legal Proceedings.” In addition, the information included in Note 17 to our Consolidated Financial Statements under the captions “Lead pigment litigation” and “Environmental matters and litigation” is incorporated herein by reference.  

Insurance - We maintain insurance for our businesses and operations, with customary levels of coverage, deductibles and limits.  See also Item 3 – “Legal Proceedings – Insurance coverage claims” and Note 16 to our Consolidated Financial Statements.  

Business strategy - We routinely compare our liquidity requirements and alternative uses of capital against the estimated future cash flows we expect to receive from our subsidiaries and affiliates.  As a result of this process, we have in the past and may in the future seek to raise additional capital, incur debt, repurchase indebtedness in the market or otherwise modify our dividend policies, consider the sale of our interests in our subsidiaries, affiliates, business, marketable securities or other assets, or take a combination of these and other steps, to increase liquidity, reduce indebtedness and fund future activities.  Such activities have in the past and may in the future involve related

- 15 -

companies.  From time to time, we also evaluate the restructuring of ownership interests among our respective subsidiaries and related companies.  

We and other entities that may be affiliated with Contran routinely evaluate acquisitions of interests in, or combinations with, companies, including related companies, perceived by management to be undervalued in the marketplace.  These companies may or may not be engaged in businesses related to our current businesses.  In some instances, we have actively managed the businesses acquired with a focus on maximizing return-on-investment through cost reductions, capital expenditures, improved operating efficiencies, selective marketing to address market niches, disposition of marginal operations, use of leverage and redeployment of capital to more productive assets.  In other instances, we have disposed of the acquired interest in a company prior to gaining control.  We intend to consider such activities in the future and may, in connection with such activities, consider issuing additional equity securities and increasing our indebtedness.  

Available information - Our fiscal year ends December 31.  We furnish our shareholders with annual reports containing audited financial statements.  In addition, we file annual, quarterly and current reports, proxy and information statements and other information with the SEC.  Our consolidated subsidiary (CompX) and our significant equity method investee (Kronos) also file annual, quarterly, and current reports, proxy and information statements and other information with the SEC.  We also make our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments thereto available free of charge through our website at www.nl-ind.com as soon as reasonably practicable after they have been filed with the SEC.  We also provide to anyone, without charge, copies of such documents upon written request.  Such requests should be directed to the attention of the Corporate Secretary at our address on the cover page of this Form 10-K.  

Additional information, including our Audit Committee charter, our Code of Business Conduct and Ethics and our Corporate Governance Guidelines can be found on our website.  Information contained on our website is not part of this Annual Report.  

The general public may read and copy any materials we file with the SEC at the SEC’s Public Reference Room at 100 F Street, NE, Washington, DC 20549.  The public may obtain information about the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330.  We are an electronic filer and the SEC maintains an internet website that contains reports, proxy and information statements and other information regarding issuers that file electronically with the SEC at www.sec.gov.  

Listed below are certain risk factors associated with us and our businesses. See also certain risk factors discussed in Item 7 – “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates.”  In addition to the potential effect of these risk factors, any risk factor which could result in reduced earnings or operating losses, or reduced liquidity, could in turn adversely affect our ability to service our liabilities or pay dividends on our common stock or adversely affect the quoted market prices for our securities.  

We could incur significant costs related to legal and environmental matters.  

We formerly manufactured lead pigments for use in paint.  We and others have been named as defendants in various legal proceedings seeking damages for personal injury, property damage and governmental expenditures allegedly caused by the use of lead-based paints.  These lawsuits seek recovery under a variety of theories, including public and private nuisance, negligent product design, negligent failure to warn, strict liability, breach of warranty, conspiracy/concert of action, aiding and abetting, enterprise liability, market share or risk contribution liability, intentional tort, fraud and misrepresentation, violations of state consumer protection statutes, supplier negligence and similar claims.  The plaintiffs in these actions generally seek to impose on the defendants responsibility for lead paint abatement and health concerns associated with the use of lead-based paints, including damages for personal injury, contribution and/or indemnification for medical expenses, medical monitoring expenses and costs for educational programs.  As with all legal proceedings, the outcome is uncertain.  Any liability we might incur in the future could be material.  See also Item 3 - “Legal Proceedings - Lead pigment litigation.”

- 16 -

Certain properties and facilities used in our former operations are the subject of litigation, administrative proceedings or investigations arising under various environmental laws.  These proceedings seek cleanup costs, personal injury or property damages and/or damages for injury to natural resources.  Some of these proceedings involve claims for substantial amounts.  Environmental obligations are difficult to assess and estimate for numerous reasons, and we may incur costs for environmental remediation in the future in excess of amounts currently estimated.  Any liability we might incur in the future could be material.  See also Item 3 - “Legal Proceedings - Environmental matters and litigation.”

Our assets consist primarily of investments in our operating subsidiaries and affiliates, and we are dependent upon distributions from our subsidiaries and affiliates.  

The majority of our operating cash flows are generated by our operating subsidiaries and affiliates, and our ability to service liabilities and to pay dividends on our common stock (to the extent such dividends are declared by our board of directors) depends to a large extent upon the cash dividends or other distributions we receive from our subsidiaries and affiliates.  Our subsidiaries and affiliates are separate and distinct legal entities and they have no obligation, contingent or otherwise, to pay such cash dividends or other distributions to us.  In addition, the payment of dividends or other distributions from our subsidiaries and affiliates could be subject to restrictions on, or taxation of, dividends or repatriation of earnings under applicable law, monetary transfer restrictions, currency exchange regulations in jurisdictions in which our subsidiaries and affiliates operate or any other restrictions imposed by current or future agreements to which our subsidiaries and affiliates may be a party, including debt instruments.  Events beyond our control, including changes in general business and economic conditions, could adversely impact the ability of our subsidiaries and affiliates to pay dividends or make other distributions to us.  If our subsidiaries and affiliates were to become unable to make sufficient cash dividends or other distributions to us, our ability to service our liabilities and to pay dividends on our common stock (if declared) could be adversely affected.  

In addition, a significant portion of our assets consist of ownership interests in our subsidiaries and affiliates.  If we were required to liquidate any of such securities in order to generate funds to satisfy our liabilities, we may be required to sell such securities at a time or times at which we would not be able to realize what we believe to be the actual value of such assets.  

We operate in mature and highly competitive markets, resulting in pricing pressure and the need to continuously reduce costs.  

Many of the markets CompX serves are highly competitive, with a number of competitors offering similar products.  CompX focuses efforts on the middle and high-end business of the market where we feel that we can compete due to the importance of product design, quality and durability to the customer.  However, our ability to effectively compete is impacted by a number of factors.  The occurrence of any of these factors could result in reduced earnings or operating losses.  

- 17 -

Our development of innovative features for our current component products is critical to sustaining and growing our sales.  

Historically, CompX’s ability to provide value-added custom engineered component products that address requirements of technology and space utilization has been a key element of its success.  CompX spends a significant amount of time and effort to refine, improve and adapt our existing products for new customers and applications.  Since expenditures for these types of activities are not considered research and development expense under accounting principles generally accepted in the United States of America, the amount of our research and development expenditures, which is not significant, is not indicative of the overall effort involved in the development of new product features.  The introduction of new product features requires the coordination of the design, manufacturing and marketing of the new product features with current and potential customers.  The ability to coordinate these activities with current and potential customers may be affected by factors beyond CompX’s control.  While we will continue to emphasize the introduction of innovative new product features that target customer-specific opportunities, we do not know if any new product features CompX introduces will achieve the same degree of success that it has achieved with its existing products.  Introduction of new product features typically requires us to increase production volume on a timely basis while maintaining product quality.  Manufacturers often encounter difficulties in increasing production volumes, including delays, quality control problems and shortages of qualified personnel or raw materials.  As CompX attempts to introduce new product features in the future, we do not know if CompX will be able to increase production volume without encountering these or other problems, which might negatively impact our financial condition or results of operations.  

Future acquisitions of CompX could subject us to a number of operational risks.  

A key component of CompX’s strategy is to grow and diversify its business through targeted acquisitions.  CompX’s ability to successfully execute this component of its strategy entails a number of risks, including:

Failure to protect our intellectual property rights or claims by others that we infringe their intellectual property rights could substantially harm our business.  

CompX relies on patent, trademark and trade secret laws in the United States and similar laws in other countries to establish and maintain intellectual property rights in our technology and designs.  Despite these measures, any of our intellectual property rights could be challenged, invalidated, circumvented or misappropriated.  Others may independently discover our trade secrets and proprietary information, and in such cases we could not assert any trade secret rights against such parties.  Further, we do not know if any of our pending trademark or patent applications will be approved.  Costly and time-consuming litigation could be necessary to enforce and determine the scope of our intellectual property rights.  In addition, the laws of certain countries do not protect intellectual property rights to the same extent as the laws of the United States.  Therefore, in certain jurisdictions, we may be unable to protect our technology and designs adequately against unauthorized third party use, which could adversely affect our competitive position.  

Third parties may claim that we or our customers are infringing upon their intellectual property rights.  Even if we believe that such claims are without merit, they can be time-consuming and costly to defend and distract our management’s and technical staff’s attention and resources.  Claims of intellectual property infringement also might require us to redesign affected technology, enter into costly settlement or license agreements or pay costly damage awards, or face a temporary or permanent injunction prohibiting us from marketing or selling certain of our

- 18 -

technology.  If we cannot or do not license the infringed technology on reasonable pricing terms or at all, or substitute similar technology from another source, our business could be adversely impacted.  

Global climate change legislation could negatively impact our financial results or limit our ability to operate our businesses.  

CompX operates production facilities in the United States and Kronos operates production facilities in several countries in North America and Europe.  We believe that all production facilities are in substantial compliance with applicable environmental laws.  Legislation has been passed, or proposed legislation is being considered, to limit greenhouse gases through various means including emissions permits and/or energy taxes.  In several production facilities, Kronos consumes large amounts of energy, primarily electricity and natural gas.  To date the climate change legislation in effect has not had a material adverse effect on our financial results.  However, if further greenhouse gas legislation were to be enacted in one or more countries, it could negatively impact our future results from operations through increased costs of production, particularly as it relates to our energy requirements or our need to obtain emissions permits.  If such increased costs of production were to materialize, we may be unable to pass price increases onto our customers to compensate for increased production costs, which may decrease our liquidity, income from operations and results of operations.  

Higher costs or limited availability of our raw materials may decrease our liquidity.  

Certain of the raw materials used in CompX’s products are commodities that are subject to significant fluctuations in price in response to world-wide supply and demand as well as speculative investor activity.  Zinc and brass are the principal raw materials used in the manufacture of security products.  Stainless steel tubing is the major raw material used in the manufacture of marine exhaust systems.  These raw materials are purchased from several suppliers and are generally readily available from numerous sources.  CompX occasionally enters into short-term raw material supply arrangements to mitigate the impact of future increases in commodity-related raw material costs.  Materials purchased outside of these arrangements are sometimes subject to unanticipated and sudden price increases.  Should our vendors not be able to meet their contractual obligations or should we otherwise be unable to obtain necessary raw materials, we may incur higher costs for raw materials or may be required to reduce production levels, either of which may decrease our liquidity or negatively impact our financial condition or results of operations as we may be unable to offset the higher costs with increases in our selling prices or reductions in other operating costs.  

For Kronos, the number of sources for and availability of certain raw materials is specific to the particular geographical region in which a facility is located.  For example, titanium-containing feedstocks suitable for use in its TiO₂ facilities are available from a limited number of suppliers around the world.  Political and economic instability in the countries from which Kronos purchases raw material supplies could adversely affect their availability.  If Kronos’ worldwide vendors were unable to meet their contractual obligations and it was unable to obtain necessary raw materials, Kronos could incur higher costs for raw materials or may be required to reduce production levels.  Kronos experienced significantly higher ore costs in 2012 which carried over into 2013.  Kronos has seen moderation in the purchase cost of third-party feedstock ore in 2013 and throughout 2014 and 2015, but such reductions did not begin to be significantly reflected in Kronos’ cost of sales until the third quarter of 2013.  Kronos may also experience higher operating costs such as energy costs, which could affect its profitability.  Kronos may not always be able to increase selling prices to offset the impact of any higher costs or reduced production levels, which could reduce its earnings and decrease its liquidity.  

Kronos has long-term supply contracts that provide for its TiO₂ feedstock requirements that currently expire through 2019.  While Kronos believes it will be able to renew these contracts, there can be no assurance it will be successful in renewing these contracts or in obtaining long-term extensions to these contracts prior to expiration.  Kronos’ current agreements (including those entered into through February 2016) require Kronos to purchase certain minimum quantities of feedstock with minimum purchase commitments aggregating approximately $865 million in years subsequent to December 31, 2015.  In addition, Kronos has other long-term supply and service contracts that provide for various raw materials and services.  These agreements require Kronos to purchase certain minimum quantities or services with minimum purchase commitments aggregating approximately $147 million at December 31, 2015.  Kronos’ commitments under these contracts could adversely affect its financial results if it significantly reduced production and was unable to modify the contractual commitments.  

- 19 -

Demand for, and prices of, certain of Kronos’ products are influenced by changing market conditions for its products, which may result in reduced earnings or in operating losses.  

A significant portion of our net income is attributable to sales of TiO₂ by Kronos.  Approximately 90% of Kronos’ revenues are attributable to sales of TiO₂.  Pricing within the global TiO₂ industry over the long term is cyclical, and changes in economic conditions, especially in Western industrialized nations, can significantly impact Kronos’ earnings and operating cash flows.  Historically, the markets for many of Kronos’ products have experienced alternating periods of increasing and decreasing demand.  Relative changes in the selling prices for Kronos’ products are one of the main factors that affect the level of its profitability.  In periods of increasing demand, Kronos’ selling prices and profit margins generally will tend to increase, while in periods of decreasing demand Kronos’ selling prices and profit margins generally tend to decrease.  In addition, pricing may affect customer inventory levels as customers may from time to time accelerate purchases of TiO₂ in advance of anticipated price increases or defer purchases of TiO₂ in advance of anticipated price decreases.  Kronos’ ability to further increase capacity without additional investment in greenfield or brownfield capacity increases may be limited and as a result, Kronos’ profitability may become even more dependent upon the selling prices of its products.  

The TiO₂ industry is concentrated and highly competitive and Kronos faces price pressures in the markets in which it operates, which may result in reduced earnings or operating losses.  

The global market in which Kronos operates is concentrated, with the top five TiO₂ producers accounting for over 50% of the world’s production capacity and is highly competitive.  Competition is based on a number of factors, such as price, product quality and service.  Some of Kronos’ competitors may be able to drive down prices for its products if their costs are lower than Kronos’ costs.  In addition, some of the competitors’ financial, technological and other resources may be greater than Kronos’ resources and such competitors may be better able to withstand changes in market conditions.  Kronos’ competitors may be able to respond more quickly to new or emerging technologies and changes in customer requirements.  Further, consolidation of competitors or customers may result in reduced demand for Kronos’ products or make it more difficult for Kronos to compete with competitors.  The occurrence of any of these events could result in reduced earnings or operating losses.  

Kronos’ leverage may impair our financial condition or limit our ability to operate our businesses.  

As of December 31, 2015, Kronos had consolidated debt of approximately $341.0 million, which relates primarily to a term loan entered into in February 2014.  Kronos’ level of debt could have important consequences to its stockholders (including us) and creditors, including:

In addition to Kronos’ indebtedness, at December 31, 2015, Kronos is party to various lease and other agreements (including feedstock ore purchase contracts and other long-term supply and service contracts as discussed above) pursuant to which, along with its indebtedness, Kronos is committed to pay approximately $453 million in 2016.  Kronos’ ability to make payments on and refinance its debt and to fund planned capital expenditures depends on Kronos’ future ability to generate cash flow.  To some extent, this is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.  In addition, Kronos’ ability to borrow funds under its revolving credit facilities in the future will, in some instances, depend in part on its ability to maintain specified financial ratios and satisfy certain financial covenants contained in the applicable credit agreement.  

- 20 -

Kronos’ business may not generate cash flows from operating activities sufficient to enable Kronos to pay its debts when they become due and to fund other liquidity needs.  As a result, Kronos may need to refinance all or a portion of its debt before maturity.  Kronos may not be able to refinance any of its debt in a timely manner on favorable terms, if at all in the current credit markets.  Any inability to generate sufficient cash flows or to refinance Kronos’ debt on favorable terms could have a material adverse effect on its financial condition.

Our principal executive offices are located in an office building located at 5430 LBJ Freeway, Dallas, Texas, 75240-2697.  The principal properties used in the operations of our subsidiaries and affiliates, including certain risks and uncertainties related thereto, are described in the applicable business sections of Item 1 – “Business.” We believe that our facilities are generally adequate and suitable for our respective uses.  

We are involved in various legal proceedings.  In addition to information that is included below, we have included certain of the information called for by this Item in Note 17 to our Consolidated Financial Statements, and we are incorporating that information here by reference.  

Lead pigment litigation

Our former operations included the manufacture of lead pigments for use in paint and lead-based paint.  We, other former manufacturers of lead pigments for use in paint and lead-based paint (together, the “former pigment manufacturers”), and the Lead Industries Association (LIA), which discontinued business operations in 2002, have been named as defendants in various legal proceedings seeking damages for personal injury, property damage and governmental expenditures allegedly caused by the use of lead-based paints.  Certain of these actions have been filed by or on behalf of states, counties, cities or their public housing authorities and school districts, and certain others have been asserted as class actions.  These lawsuits seek recovery under a variety of theories, including public and private nuisance, negligent product design, negligent failure to warn, strict liability, breach of warranty, conspiracy/concert of action, aiding and abetting, enterprise liability, market share or risk contribution liability, intentional tort, fraud and misrepresentation, violations of state consumer protection statutes, supplier negligence and similar claims.

The plaintiffs in these actions generally seek to impose on the defendants responsibility for lead paint abatement and health concerns associated with the use of lead-based paints, including damages for personal injury, contribution and/or indemnification for medical expenses, medical monitoring expenses and costs for educational programs.  To the extent the plaintiffs seek compensatory or punitive damages in these actions, such damages are generally unspecified.  In some cases, the damages are unspecified pursuant to the requirements of applicable state law.  A number of cases are inactive or have been dismissed or withdrawn.  Most of the remaining cases are in various pre-trial stages.  Some are on appeal following dismissal or summary judgment rulings or a trial verdict in favor of either the defendants or the plaintiffs.

We believe that these actions are without merit, and we intend to continue to deny all allegations of wrongdoing and liability and to defend against all actions vigorously.  We do not believe it is probable that we have incurred any liability with respect to all of the lead pigment litigation cases to which we are a party, and liability to us that may result, if any, in this regard cannot be reasonably estimated, because:

- 21 -

Accordingly, we have not accrued any amounts for any of the pending lead pigment and lead-based paint litigation cases filed by or on behalf of states, counties, cities or their public housing authorities and school districts, or those asserted as class actions. In addition, we have determined that liability to us which may result, if any, cannot be reasonably estimated because there is no prior history of a loss of this nature on which an estimate could be made and there is no substantive information available upon which an estimate could be based.

In one of these lead pigment cases, in April 2000 we were served with a complaint in County of Santa Clara v. Atlantic Richfield Company, et al, (Superior Court of the State of California, County of Santa Clara, Case No. 1-00-CV-788657) brought by a number of California government entities against the former pigment manufacturers, the LIA and certain paint manufacturers.  The County of Santa Clara sought to recover compensatory damages for funds the plaintiffs had expended or would in the future expend for medical treatment, educational expenses, abatement or other costs due to exposure to, or potential exposure to, lead paint, disgorgement of profit, and punitive damages.  In July 2003, the trial judge granted defendants’ motion to dismiss all remaining claims.  Plaintiffs appealed and the intermediate appellate court reinstated public nuisance, negligence, strict liability, and fraud claims in March 2006.  A fourth amended complaint was filed in March 2011 on behalf of The People of California by the County Attorneys of Alameda, Ventura, Solano, San Mateo, Los Angeles and Santa Clara, and the City Attorneys of San Francisco, San Diego and Oakland.  That complaint alleged that the presence of lead paint created a public nuisance in each of the prosecuting jurisdictions and sought its abatement.  In July and August 2013, the case was tried.  In January 2014, the Judge issued a judgment finding us, The Sherwin Williams Company and ConAgra Grocery Products Company jointly and severally liable for the abatement of lead paint in pre-1980 homes, and ordered the defendants to pay an aggregate $1.15 billion to the people of the State of California to fund such abatement. In February 2014, we filed a motion for a new trial, and in March 2014 the court denied the motion.  Subsequently in March 2014, we filed a notice of appeal with the Sixth District Court of Appeal for the State of California and the appeal is proceeding with the appellate court. NL believes that this judgment is inconsistent with California law and is unsupported by the evidence, and we will defend vigorously against all claims.

The Santa Clara case is unusual in that this is the second time that an adverse verdict in the lead pigment litigation has been entered against NL (the first adverse verdict against NL was ultimately overturned on appeal). We have concluded that the likelihood of a loss in this case has not reached a standard of “probable” as contemplated by ASC 450, given (i) the substantive, substantial and meritorious grounds on which the adverse verdict in the Santa Clara case will be appealed, (ii) the uniqueness of the Santa Clara verdict (i.e. no final, non-appealable verdicts have ever been rendered against us, or any of the other former lead pigment manufacturers, based on the public nuisance theory of liability or otherwise), and (iii) the rejection of the public nuisance theory of liability as it relates to lead pigment matters in many other jurisdictions (no jurisdiction in which a plaintiff has asserted a public nuisance theory of liability has ever successfully been upheld).  In addition, liability that may result, if any, cannot be reasonably estimated, as NL continues to have no basis on which an estimate of liability could be made, as discussed above. However, as with any legal proceeding, there is no assurance that any appeal would be successful, and it is reasonably possible, based on the outcome of the appeals process, that NL may in the future incur some liability resulting in the recognition of a loss contingency accrual that could have a material adverse impact on our results of operations, financial position and liquidity.

In June 2000, a complaint was filed in Illinois state court, Lewis, et al. v. Lead Industries Association, et al (Circuit Court of Cook County, Illinois, County Department, Chancery Division, Case No. 00CH09800.)  Plaintiffs seek to represent two classes, one consisting of minors between the ages of six months and six years who resided in housing in Illinois built before 1978, and another consisting of individuals between the ages of six and twenty years who lived in Illinois housing built before 1978 when they were between the ages of six months and six years and who had blood lead levels of 10 micrograms/deciliter or more.  The complaint seeks damages jointly and severally from the former pigment manufacturers and the LIA to establish a medical screening fund for the first class to determine blood lead levels, a medical monitoring fund for the second class to detect the onset of latent diseases and a fund for a public education campaign.  In April 2008, the trial court judge certified a class of children whose blood lead levels were screened venously between August 1995 and February 2008 and who had incurred expenses

associated with such screening.  In March 2012, the trial court judge decertified the class.  In June 2012, the trial court judge granted plaintiffs the right to appeal his decertification order, and in August 2012 the appellate court granted plaintiffs permission to appeal.  In March 2013, the appellate court agreed with the trial court’s rationale regarding legislative requirements to screen children’s blood lead levels and remanded the case for further proceedings in the trial court.  In July 2013, plaintiffs moved to vacate the decertification.  In October 2013, the judge denied plaintiffs’ motion to vacate the decertification of the class.  In March 2014, plaintiffs filed a new class certification motion.  In April 2015, a class was certified consisting of parents or legal guardians of children who lived in certain “high risk” areas in Illinois between August 18, 1995 and February 19, 2008, and incurred an expense or liability for having their children’s blood lead levels tested.

In addition to the foregoing litigation, various legislation and administrative regulations have, from time to time, been proposed that seek to (a) impose various obligations on present and former manufacturers of lead pigment and lead-based paint with respect to asserted health concerns associated with the use of such products and (b) effectively overturn court decisions in which we and other pigment manufacturers have been successful.  Examples of such proposed legislation include bills which would permit civil liability for damages on the basis of market share, rather than requiring plaintiffs to prove that the defendant’s product caused the alleged damage, and bills which would revive actions barred by the statute of limitations.  While no legislation or regulations have been enacted to date that are expected to have a material adverse effect on our consolidated financial position, results of operations or liquidity, the imposition of market share liability or other legislation could have such an effect.  

New cases may continue to be filed against us.  We cannot assure you that we will not incur liability in the future in respect of any of the pending or possible litigation in view of the inherent uncertainties involved in court and jury rulings.  In the future, if new information regarding such matters becomes available to us (such as a final, non-appealable adverse verdict against us or otherwise ultimately being found liable with respect to such matters), at that time we would consider such information in evaluating any remaining cases then-pending against us as to whether it might then have become probable we have incurred liability with respect to these matters, and whether such liability, if any, could have become reasonably estimable.  The resolution of any of these cases could result in the recognition of a loss contingency accrual that could have a material adverse impact on our net income for the interim or annual period during which such liability is recognized and a material adverse impact on our consolidated financial condition and liquidity.  

Environmental matters and litigation

Our operations are governed by various environmental laws and regulations.  Certain of our businesses are and have been engaged in the handling, manufacture or use of substances or compounds that may be considered toxic or hazardous within the meaning of applicable environmental laws and regulations.  As with other companies engaged in similar businesses, certain of our past and current operations and products have the potential to cause environmental or other damage.  We have implemented and continue to implement various policies and programs in an effort to minimize these risks.  Our policy is to maintain compliance with applicable environmental laws and regulations at all of our plants and to strive to improve environmental performance.  From time to time, we may be subject to environmental regulatory enforcement under U.S. and non-U.S. statutes, the resolution of which typically involves the establishment of compliance programs.  It is possible that future developments, such as stricter requirements of environmental laws and enforcement policies, could adversely affect our production, handling, use, storage, transportation, sale or disposal of such substances.  We believe that all of our facilities are in substantial compliance with applicable environmental laws.  

Certain properties and facilities used in our former operations, including divested primary and secondary lead smelters and former mining locations, are the subject of civil litigation, administrative proceedings or investigations arising under federal and state environmental laws and common law.  Additionally, in connection with past operating practices, we are currently involved as a defendant, potentially responsible party (PRP) or both, pursuant to the Comprehensive Environmental Response, Compensation and Liability Act, as amended by the Superfund Amendments and Reauthorization Act (CERCLA), and similar state laws in various governmental and private actions associated with waste disposal sites, mining locations, and facilities that we or our predecessors, our subsidiaries or their predecessors currently or previously owned, operated or used, certain of which are on the United States Environmental Protection Agency’s (EPA) Superfund National Priorities List or similar state lists.  These proceedings seek cleanup costs, damages for personal injury or property damage and/or damages for injury to

- 23 -

natural resources.  Certain of these proceedings involve claims for substantial amounts.  Although we may be jointly and severally liable for these costs, in most cases we are only one of a number of PRPs who may also be jointly and severally liable, and among whom costs may be shared or allocated.  In addition, we are also a party to a number of personal injury lawsuits filed in various jurisdictions alleging claims related to environmental conditions alleged to have resulted from our operations.  

Obligations associated with environmental remediation and related matters are difficult to assess and estimate for numerous reasons including the:

In addition, the imposition of more stringent standards or requirements under environmental laws or regulations, new developments or changes regarding site cleanup costs or the allocation of costs among PRPs, solvency of other PRPs, the results of future testing and analysis undertaken with respect to certain sites or a determination that we are potentially responsible for the release of hazardous substances at other sites, could cause our expenditures to exceed our current estimates.  We cannot assure you that actual costs will not exceed accrued amounts or the upper end of the range for sites for which estimates have been made, and we cannot assure you that costs will not be incurred for sites where no estimates presently can be made.  Further, additional environmental and related matters may arise in the future.  If we were to incur any future liability, this could have a material adverse effect on our consolidated financial statements, results of operations and liquidity.  

We record liabilities related to environmental remediation and related matters (including costs associated with damages for personal injury or property damage and/or damages for injury to natural resources) when estimated future expenditures are probable and reasonably estimable.  We adjust such accruals as further information becomes available to us or as circumstances change.  Unless the amounts and timing of such estimated future expenditures are fixed and reasonably determinable, we generally do not discount estimated future expenditures to their present value due to the uncertainty of the timing of the payout.  We recognize recoveries of costs from other parties, if any, as assets when their receipt is deemed probable.  At December 31, 2014 and 2015, we have not recognized any receivables for recoveries.  

We do not know and cannot estimate the exact time frame over which we will make payments for our accrued environmental and related costs.  The timing of payments depends upon a number of factors, including but not limited to the timing of the actual remediation process; which in turn depends on factors outside of our control.  At each balance sheet date, we estimate the amount of our accrued environmental and related costs which we expect to pay within the next twelve months, and we classify this estimate as a current liability.  We classify the remaining accrued environmental costs as a noncurrent liability.  

On a quarterly basis, we evaluate the potential range of our liability for environmental remediation and related costs at sites where we have been named as a PRP or defendant, including sites for which our wholly-owned environmental management subsidiary, NL Environmental Management Services, Inc., (EMS), has contractually assumed our obligations.  At December 31, 2015, we had accrued approximately $113 million related to approximately 42 sites associated with remediation and related matters that we believe are at the present time and/or in their current phase reasonably estimable.  The upper end of the range of reasonably possible costs to us for remediation and related matters for which we believe it is possible to estimate costs is approximately $166 million, including the amount currently accrued.

- 24 -

We believe that it is not reasonably possible to estimate the range of costs for certain sites.  At December 31, 2015, there were approximately 5 sites for which we are not currently able to reasonably estimate a range of costs.  For these sites, generally the investigation is in the early stages, and we are unable to determine whether or not we actually had any association with the site, the nature of our responsibility, if any, for the contamination at the site and the extent of contamination at and cost to remediate the site.  The timing and availability of information on these sites is dependent on events outside of our control, such as when the party alleging liability provides information to us.  At certain of these previously inactive sites, we have received general and special notices of liability from the EPA and/or state agencies alleging that we, sometimes with other PRPs, are liable for past and future costs of remediating environmental contamination allegedly caused by former operations.  These notifications may assert that we, along with any other alleged PRPs, are liable for past and/or future clean-up costs.  As further information becomes available to us for any of these sites, which would allow us to estimate a range of costs, we would at that time adjust our accruals.  Any such adjustment could result in the recognition of an accrual that would have a material effect on our consolidated financial statements, results of operations and liquidity.

In June 2006, we and several other PRPs received a Unilateral Administrative Order (UAO) from the EPA regarding a formerly-owned mine and milling facility located in Park Hills, Missouri.  The Doe Run Company is the current owner of the site, which was purchased by a predecessor of Doe Run from us in approximately 1936.  Doe Run is also named in the Order.  In April 2008, the parties signed a definitive cost sharing agreement for sharing of the costs anticipated in connection with the order and in May 2008, the parties began work at the site as required by the UAO and in accordance with the cost sharing agreement.  In the fourth quarter of 2010, NL reached its capped payment obligation under the cost sharing agreement with Doe Run.  In the fourth quarter of 2013, Doe Run completed the remainder of the construction work. A Removal Action Report and Post-Removal Site Control plan is expected to be submitted to the EPA by Doe Run in 2016.

In June 2008, we received a Directive and Notice to Insurers from the New Jersey Department of Environmental Protection (NJDEP) regarding the Margaret’s Creek site in Old Bridge Township, New Jersey.  NJDEP alleged that a waste hauler transported waste from one of our former facilities for disposal at the site in the early 1970s.  NJDEP referred the site to the EPA, and in November 2009, the EPA added the site to the National Priorities List under the name “Raritan Bay Slag Site.”  In 2012, EPA notified NL of its potential liability at this site.  In May 2013, EPA issued its Record of Decision for the site.  In June 2013, NL filed a contribution suit under CERCLA and the New Jersey Spill Act titled NL Industries, Inc. v. Old Bridge Township, et al. (United States District Court for the District of New Jersey, Civil Action No. 3:13-cv-03493-MAS-TJB) against the current owner, Old Bridge Township, and several federal and state entities NL alleges designed and operated the site and who have significant potential liability as compared to NL which is alleged to have been a potential source of material placed at the site by others.  NL’s suit also names certain former NL customers of the former NL facility alleged to be the source of some of the materials.  In January 2014, EPA issued a UAO to NL for clean-up of the site based on the EPA’s preferred remedy set forth in the Record of Decision.   NL is in discussions with EPA about NL’s performance of a defined amount of the work at the site and is otherwise taking actions necessary to respond to the UAO.  If these discussions and actions are unsuccessful, NL will defend vigorously against all claims while continuing to seek contribution from other PRPs.  

In September 2008, we received a Special Notice letter from the EPA for liability associated with the Tar Creek Superfund site in Ottawa County, Oklahoma (Tar Creek) and a demand for related past and future costs.  We responded with a good-faith offer to pay certain of the EPA’s past costs and to complete limited work in the areas in which we operated.  In October 2008, we received a claim from the State of Oklahoma for past, future and relocation costs in connection with the site.  In November 2015, the United States Department of Justice lodged with the federal court a fully-executed consent decree between the United States, the State of Oklahoma and NL that resolves the claims of the United States and the State of Oklahoma for past and future cleanup costs at Tar Creek.  The consent decree will become effective after it has been reviewed and officially approved by the federal court.

In August 2009, we were served with a complaint in Raritan Baykeeper, Inc.  d/b/a NY/NJ Baykeeper et al. v.  NL Industries, Inc.  et al.  (United States District Court, District of New Jersey, Case No.  3:09-cv-04117).  This is a citizen’s suit filed by two local environmental groups pursuant to the Resource Conservation and Recovery Act and the Clean Water Act against NL, current owners, developers and state and local government entities.  The complaint alleges that hazardous substances were and continue to be discharged from our former Sayreville, New Jersey property into the sediments of the adjacent Raritan River.  The former Sayreville site is currently being remediated by owner/developer parties under the oversight of the NJDEP.  The plaintiffs seek a declaratory

- 25 -

judgment, injunctive relief, imposition of civil penalties and an award of costs.  We have denied liability and will defend vigorously against all claims.

In June 2011, we were served in ASARCO LLC v.  NL Industries, Inc., et al.  (United States District Court, Western District of Missouri, Case No.  4:11-cv-00138-DGK).  The plaintiff brought this CERCLA contribution action against several defendants to recover a portion of the amount it paid in settlement with the U.S.  Government during its Chapter 11 bankruptcy in relation to the Tar Creek site, the Cherokee County Superfund Site in southeast Kansas, the Oronogo-Duenweg Lead Mining Belt Superfund Site in Jasper County, Missouri and the Newton County Mine Tailing Site in Newton County, Missouri.  We have denied liability and will defend vigorously against all of the claims.  In the second quarter of 2012, NL filed a motion to stay the case.  In the first quarter of 2013, NL’s motion was granted and the court entered an indefinite stay.  In the first quarter of 2015, Asarco was granted permission to seek an interlocutory appeal of that stay order.  In March 2015, the Eighth Circuit Court of Appeals denied Asarco’s request for an interlocutory appeal of the stay order and the trial court’s indefinite stay remains in place.

In September 2011, we were served in ASARCO LLC v.  NL Industries, Inc., et al.  (United States District Court, Eastern District of Missouri, Case No.  4:11-cv-00864).  The plaintiff brought this CERCLA contribution action against several defendants to recover a portion of the amount it paid in settlement with the U.S. Government during its Chapter 11 bankruptcy in relation to the Southeast Missouri Mining District.  In May 2015, the trial court on its own motion entered an indefinite stay of the litigation.  In June 2015, Asarco filed an appeal of the stay in the Eighth Circuit Court of Appeals.  NL has moved to dismiss that appeal as improperly filed.  In October 2015, the Eighth Circuit Court of Appeals granted NL’s motion to dismiss Asarco’s appeal and the trial court’s indefinite stay remains in place.  

In July 2012, we were served in EPEC Polymers, Inc., v.  NL Industries, Inc., (United States District Court for the District of New Jersey, Case 3:12-cv-03842-PGS-TJB).  The plaintiff, a landowner of property located across the Raritan River from our former Sayreville, New Jersey operation, claims that contaminants from NL’s former Sayreville operation came to be located on its land.  The complaint seeks compensatory and punitive damages and alleges, among other things, trespass, private nuisance, negligence, strict liability, and claims under CERCLA and the New Jersey Spill Act.  We have denied liability and will defend vigorously against all of the claims.  

In March 2013, NL received Special Notice from EPA for Operable Unit 1, residential area, at the Big River Mine Tailings Superfund Site in St. Francois County, Missouri.  The site encompasses approximately eight former mine and mill areas, only one of which is associated with former NL operations, as well as adjacent residential areas.  NL initiated a dialog with EPA regarding a potential settlement for this operable unit.

In September 2013, EPA issued to NL and 34 other PRPs general notice of potential liability and a demand for payment of past costs and performance of a Remedial Design for the Gowanus Canal Superfund Site in Brooklyn, New York.  In March 2014, EPA issued a UAO to NL and approximately 27 other PRPs for performance of the Remedial Design at the site.  EPA contends that NL is liable as the alleged successor to the Doehler Die Casting Company, and therefore responsible for any potential contamination at the Site resulting from Doehler’s ownership/operation of a warehouse and a die casting plant it owned 90 years ago. NL believes that it has no liability at the Site.  NL is currently in discussions with EPA regarding a de minimis settlement and is otherwise taking actions necessary to respond to the UAO. If these discussions are unsuccessful, NL will continue to deny liability and will defend vigorously against all of the claims.

Other litigation

In addition to the matters described above, we and our affiliates are also involved in various other environmental, contractual, product liability, patent (or intellectual property), employment and other claims and disputes incidental to present and former businesses.  In certain cases, we have insurance coverage for these items, although we do not expect additional material insurance coverage for environmental matters.  

We currently believe that the disposition of all claims and disputes, individually or in the aggregate, should not have a material adverse effect on our consolidated financial position, results of operations or liquidity beyond the accruals already provided.  

- 26 -

Insurance coverage claims

We are involved in certain legal proceedings with a number of our former insurance carriers regarding the nature and extent of the carriers’ obligations to us under insurance policies with respect to certain lead pigment and asbestos lawsuits.  The issue of whether insurance coverage for defense costs or indemnity or both will be found to exist for our lead pigment and asbestos litigation depends upon a variety of factors and we cannot assure you that such insurance coverage will be available.  In addition to information that is included below, we have included certain of the information called for by this Item in Note 17 to our Consolidated Financial Statements, and we are incorporating that information here by reference.  

We have agreements with certain of our former insurance carriers pursuant to which the carriers reimburse us for a portion of our future lead pigment litigation defense costs, and one such carrier reimburses us for a portion of our future asbestos litigation defense costs.  We are not able to determine how much we will ultimately recover from these carriers for defense costs incurred by us because of certain issues that arise regarding which defense costs qualify for reimbursement.  While we continue to seek additional insurance recoveries, we do not know if we will be successful in obtaining reimbursement for either defense costs or indemnity.  Accordingly, we recognize insurance recoveries in income only when receipt of the recovery is probable and we are able to reasonably estimate the amount of the recovery.  See Note 16 to our Consolidated Financial Statements.  

We have settled insurance coverage claims concerning environmental claims with certain of our principal former insurance carriers.  We do not expect further material settlements relating to environmental remediation coverage.

RESULTS OF OPERATIONS

Business overview

We are primarily a holding company.  We operate in the component products industry through our majority-owned subsidiary, CompX International Inc.  We also own a noncontrolling interest in Kronos Worldwide, Inc.  Both CompX (NYSE MKT: CIX) and Kronos (NYSE: KRO) file periodic reports with the SEC.  

CompX is a leading manufacturer of engineered components utilized in a variety of applications and industries.  Through its Security Products operations, CompX manufactures mechanical and electronic cabinet locks and other locking mechanisms used in recreational transportation, postal, office and institutional furniture, cabinetry, tool storage and healthcare applications.  CompX also manufactures stainless steel exhaust systems, gauges, throttle controls, and trim tabs for the recreational marine and other industries through its Marine Components operations.

We account for our 30% non-controlling interest in Kronos by the equity method.  Kronos is a leading global producer and marketer of value-added titanium dioxide pigments.  TiO₂ is used for a variety of manufacturing applications including coatings, plastics, paper and other industrial products.  

Net income (loss) overview

Our net loss attributable to NL stockholders was $23.9 million, or $.49 per share, in 2015 compared to net income of $28.5 million, or $.59 per share, in 2014 and a net loss of $55.3 million, or $1.14 per share in 2013.  

As more fully described below, the decrease in our earnings per share from 2014 to 2015 is primarily related to:

As more fully described below, the increase in our earnings per share from 2013 to 2014 is primarily due to:

Our 2015 net loss attributable to NL stockholders includes:

Our 2014 net income attributable to NL stockholders includes:

Our 2013 net loss attributable to NL stockholders includes:

Outlook for 2016

We currently expect our net income attributable to NL stockholders in 2016 to be higher than 2015 primarily due to higher equity in earnings from Kronos and lower environmental and related costs in 2016, offset in part by lower income from operations attributable to CompX.

Critical accounting policies and estimates

The accompanying “Management’s Discussion and Analysis of Financial Condition and Results of Operations” is based upon our Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP).  The preparation of these financial statements requires us to make estimates and judgments 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 amount of revenues and expenses during the reported period.  On an ongoing basis, we evaluate our estimates, including those related to the recoverability of long-lived assets, pension and other postretirement benefit obligations and the underlying actuarial assumptions related thereto, the realization of deferred income tax assets and accruals for litigation, income tax and other contingencies.  We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the reported amounts of assets, liabilities, revenues and expenses.  Actual results may differ significantly from previously-estimated amounts under different assumptions or conditions.

The following critical accounting policies affect our more significant judgments and estimates used in the preparation of our Consolidated Financial Statements:

Income from operations of CompX and Kronos is impacted by certain significant judgments and estimates, as summarized below:

In addition, general corporate and other items are impacted by the significant judgments and estimates for impairment of marketable securities and equity method investments, defined benefit pension and OPEB plans, deferred income tax asset valuation allowances and loss accruals.

Income (loss) from operations

The following table shows the components of our income (loss) from operations.

The following table shows the components of our income (loss) before income taxes exclusive of our income (loss) from operations.

- 34 -

 CompX International Inc.

Net sales - Net sales increased $5.2 million in 2015 led by strong demand within CompX’s Security Products business from existing government customers. Sales from CompX’s Marine Components business also contributed to the increase primarily through higher sales to the waterski/wakeboard boat market.  Relative changes in selling prices did not have a material impact on net sales comparisons.

Net sales increased $11.8 million in 2014 principally due to strong demand within CompX’s Security Products business, including a new initiative for an existing government customer, increased market penetration in electronic locks and strong demand in transportation markets.  Sales from CompX’s Marine Components business also contributed to the increase, reflecting greater penetration into non high-performance marine markets.  Relative changes in selling prices did not have a material impact on net sales comparisons.

Cost of sales and gross margin - Cost of sales and gross margin both increased from 2014 to 2015 primarily due to increased sales volumes.  As a percentage of sales, cost of sales and resulting gross margin for 2015 is comparable to 2014 as improved variable margins and manufacturing efficiencies attributable to CompX’s Marine Components business were substantially offset by slightly lower variable margins and increased fixed costs within CompX’s Security Products business.

Cost of sales and gross margin both increased from 2013 to 2014 primarily due to increased sales volumes.  As a percentage of sales, cost of sales decreased 1% primarily due to improved coverage of fixed manufacturing costs over increased production volumes to meet higher demand for CompX’s products, partially offset by the impact of lower variable margins due to relative changes in customer and product mix within CompX’s Security Products business.

Operating costs and expenses - Operating costs and expenses consist primarily of sales and administrative related personnel costs, sales commissions and advertising expenses directly related to product sales and administrative costs relating to CompX’s business and corporate management activities, as well as gains and losses on plant, property and equipment. Operating costs and expenses increased slightly in 2015 primarily as a result of increased personnel costs for CompX’s Security Products business.   Operating costs and expenses increased slightly in 2014 compared to 2013 primarily as a result of increased administrative personnel costs and increased depreciation for CompX’s Security Products business, partially offset by reduced corporate administrative personnel costs.  

Income from operations - As a percentage of net sales, income from operations in 2015 was comparable to 2014, and increased by 3% in 2014 compared to 2013.  The operating margins were primarily impacted by the factors impacting cost of sales, gross margin and operating costs discussed above.  

- 35 -

General - CompX’s profitability primarily depends on our ability to utilize our production capacity effectively, which is affected by, among other things, the demand for our products and our ability to control our manufacturing costs, primarily comprised of labor costs and materials.  The materials used in our products consist of purchased components and raw materials some of which are subject to fluctuations in the commodity markets such as zinc, brass and stainless steel.  Total material costs represented approximately 48% of our cost of sales in 2015, with commodity-related raw materials accounting for approximately 10% of our cost of sales.  With the exception of a moderate midyear 2014 increase in mined metals, including zinc, worldwide commodity raw material costs were mostly stable during 2013 and 2014.  During 2015, markets for our primary commodity-related raw materials, including zinc, brass and stainless steel, have generally softened and are expected to remain soft well into 2016.  CompX occasionally enters into short-term commodity-related raw material supply arrangements to mitigate the impact of future increases in commodity-related raw material costs.  See Item 1 - “Business- Raw Materials.”  

Results by reporting unit

The key performance indicator for CompX’s reporting units is the level of their income from operations (see discussion below).

Security Products - Security Products net sales increased 5% to $95.6 million in 2015 compared to $91.4 million in 2014.  The increase in sales is primarily due to an increase of approximately $3.0 million in sales to existing government customers.  Gross margin for 2015 decreased compared to the same period in 2014 due to relative changes in customer and product mix driving lower variable margins, and increased fixed costs.  Operating costs and expenses increased approximately $.5 million in 2015 compared to 2014 primarily as a result of increased personnel costs.  Security Products income from operations as a percentage of net sales for 2015 decreased compared to 2014 primarily as a result of the factors impacting gross margin and operating costs and expenses discussed above.

Security Products net sales increased 12% to $91.4 million in 2014 compared to $81.5 million in 2013.  The increase in sales is primarily due to an increase of approximately $5.0 million in sales of new products for an existing government customer, additional sales of $2.9 million into transportation markets on strong demand from

- 36 -

motorcycle and recreational vehicle OEM customers and a $1.7 million increase in electronic lock sales in 2014 due to increased market penetration and two significant project installations.  Gross margin for 2014 is comparable to the same period in 2013 as improved coverage of fixed costs over increased production volumes were offset by lower variable margins.  Additionally, operating costs and expenses for 2014 increased approximately $1.2 million, primarily as a result of increased administrative personnel and benefits costs of approximately $.5 million and increased depreciation of $.2 million.  Security products income from operations as a percentage of net sales for 2014 is comparable to 2013 primarily as a result of the factors impacting gross margin and operating costs and expenses discussed above.

Marine Components - Marine Components net sales increased 8% in 2015 as compared to 2014.  The increase in sales was primarily due to improved demand for products sold to the ski/wakeboard boat market, including the introduction of new product lines to that market.  As a percentage of net sales, gross margin and the income from operations percentage each improved due to improved pricing, changes in customer and product mix, improved manufacturing efficiencies and increased leverage of fixed costs as a result of higher production volumes.

Marine Components net sales increased 17% in 2014 as compared to 2013.  The increase was primarily the result of gains in market share for products sold to the ski/wakeboard boat market and other non high performance marine markets.  As a percentage of net sales, gross margin and the income from operations percentage improved primarily due to variable margins related to product mix and increased leverage of fixed costs as a result of higher volumes.

Outlook - The robust demand for our products experienced in 2015 was supported by continued high demand from certain large existing customers, including those serving the government security applications and recreational transportation markets. In addition, 2015 sales included over $5 million in sales for a government security end-user which is not expected to recur in 2016. We also continue to experience the benefits of innovation and diversification in our product offerings to the recreational boat markets served by our Marine Components segment. We anticipate continued strong demand for our products in 2016, though we do not expect demand for government security applications to approach 2015 volumes. As in prior periods, we will continue to monitor general economic conditions and sales order rates and respond to fluctuations in customer demand through continuous evaluation of staffing levels and consistent execution of our lean manufacturing and cost improvement initiatives. Additionally, we continue to seek opportunities to gain market share in markets we currently serve, to expand into new markets and to develop new product features in order to mitigate the impact of changes in demand as well as broaden our sales base.

General corporate items, interest and dividend income, interest expense, provision for income taxes, noncontrolling interest and related party transactions

Insurance recoveries - We have agreements with certain insurance carriers pursuant to which the carriers reimburse us for a portion of our past lead pigment and asbestos litigation defense costs.  Insurance recoveries include amounts we received from these insurance carriers.  Substantially all of the $3.7 million of insurance recoveries we recognized in 2015 relate to a first quarter settlement we reached with one of our insurance carriers in which they agreed to reimburse us for a portion of our past litigation defense costs. Substantially all of the $10.4 million of insurance recoveries we recognized in 2014 relate to a settlement we reached with one of our insurance carriers in September 2014 in which they agreed to reimburse us for a portion of our past litigation defense costs.

The agreements with certain of our insurance carriers also include reimbursement for a portion of our future litigation defense costs.  We are not able to determine how much we will ultimately recover from these carriers for defense costs incurred by us because of certain issues that arise regarding which defense costs qualify for reimbursement.  Accordingly, these insurance recoveries are recognized when receipt is probable and the amount is determinable.  Substantially all of the insurance recoveries recognized in 2013 relate to reimbursement of ongoing litigation defense costs.  See Notes 16 and 17 to our Consolidated Financial Statements.

Corporate expense - Corporate expenses were $17.5 million in 2015, $3.8 million or 18% lower than in 2014 primarily due to lower environmental and related costs; and lower litigation and related costs.  Included in corporate expenses are:

Corporate expenses were $21.3 million in 2014, $65.7 million or 76% lower than in 2013 primarily due to lower environmental and related costs.  Included in corporate expenses are:

Overall, we currently expect that our net general corporate expenses in 2016 will be lower than in 2015 primarily due to lower expected environmental remediation and related costs.

The level of our litigation and related expenses varies from period to period depending upon, among other things, the number of cases in which we are currently involved, the nature of such cases and the current stage of such cases (e.g. discovery, pre-trial motions, trial or appeal, if applicable).  See Note 17 to our Consolidated Financial Statements.  If our current expectations regarding the number of cases in which we expect to be involved during 2016 or the nature of such cases were to change, our corporate expenses could be higher than we currently estimate.

Obligations for environmental remediation costs are difficult to assess and estimate and it is possible that actual costs for environmental remediation will exceed accrued amounts or that costs will be incurred in the future for sites in which we cannot currently estimate our liability.  If these events were to occur in 2016, our corporate expenses would be higher than we currently estimate.  In addition, we adjust our environmental accruals as further information becomes available to us or as circumstances change.  Such further information or changed circumstances could result in an increase in our accrued environmental costs.  See Note 17 to our Consolidated Financial Statements.

Interest and dividend income – Dividend income decreased $.4 million in 2015 compared to 2014 related to the reduction of Valhi’s quarterly dividend from $.05 per share to $.02 per share, effective with its second quarter 2014 dividend.

Dividend income decreased $1.3 million in 2014 compared to 2013 related to such reduction in Valhi’s quarterly dividend.

Interest expense - Substantially all of our interest expense in 2013 relates to certain of CompX’s indebtedness.  CompX prepaid such indebtedness in July 2013, after which we have not had any outstanding indebtedness.  We do not expect to have any outstanding indebtedness during 2016.  

Income tax expense (benefit) - We recognized an income tax benefit of $41.9 million in 2013, income tax expense of $5.0 million in 2014 and an income tax benefit of $28.6 million in 2015.  Our income tax benefit in 2015 includes a first quarter non-cash income tax benefit of $3.0 million related to the release of a portion of our reserve for uncertain tax positions due to the expiration of the applicable statute of limitations.  In accordance with GAAP, we recognize deferred income taxes on our undistributed equity in earnings (losses) of Kronos.  Because we and Kronos are part of the same U.S. federal income tax group, any dividends we receive from Kronos are nontaxable to us.  Accordingly, we do not recognize and we are not required to pay income taxes on dividends from Kronos.  Therefore, our effective income tax rate will generally be lower than the U.S. federal statutory income tax rate in periods during which we receive dividends from Kronos and recognize equity in earnings of Kronos (such as in 2014).  Conversely, our effective income tax rate will generally be higher than the U.S. federal statutory income tax rate in periods during which we receive dividends from Kronos and recognize equity in losses of Kronos (such as in 2013 and 2015).  We received aggregate dividends from Kronos of $21.1 million in each of 2013, 2014 and 2015.

Our effective tax rate attributable to our equity in earnings (losses) of Kronos, including the effect of non-taxable dividends we received from Kronos, was 58.9% in 2013, 10.5% in 2014 and 49.0% in 2015.  Kronos has substantial net operating losses in Germany and Belgium, the benefit of which Kronos had previously recognized under the more-likely-than-not recognition criteria.  In the second quarter of 2015, Kronos determined that such losses did not meet the more-likely-than-not recognition criteria, and as a result Kronos recognized a non-cash deferred income tax expense of $150.3 million in the second quarter of 2015 and an additional $8.7 million of expense in the second half of 2015 as a valuation allowance against Kronos’ net deferred income tax assets in such jurisdictions.  Our equity in losses of Kronos in 2015 includes our equity in such non-cash deferred income tax expense recognized by Kronos.

See Note 13 to our Consolidated Financial Statements for more information about our 2015 income tax items, including a tabular reconciliation of our statutory tax expense (benefit) to our actual tax expense (benefit).

Noncontrolling interest - Noncontrolling interest in net income of CompX attributable to continuing operations is consistent in each of 2013, 2014 and 2015.

Related party transactions - We are a party to certain transactions with related parties.  See Notes 1 and 15 to our Consolidated Financial Statements.  It is our policy to engage in transactions with related parties on terms, in our opinion, no less favorable to us than we could obtain from unrelated parties.
