Forward-Looking Statements

This Annual Report on Form 10-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, as amended.  Statements in this Annual Report that are not historical facts are forward-looking in nature and represent management’s beliefs and assumptions based on currently available information.  In some cases, you can identify forward-looking statements by the use of words such as “believes,” “intends,” “may,” “should,” “could,” “anticipates,” “expects” or comparable terminology, or by discussions of strategies or trends.  Although we believe that the expectations reflected in such forward-looking statements are reasonable, we do not know if these expectations will be correct.  Such statements by their nature involve substantial risks and uncertainties that could significantly impact expected results.  Actual future results could differ materially from those predicted.  The factors that could cause actual future results to differ materially from those described herein are the risks and uncertainties discussed in this Annual Report and those described from time to time in our other filings with the U.S. Securities and Exchange Commission (the “SEC”) and include, but are not limited to, the following:

• Future demand for our products,

• Changes in our raw material and other operating costs (such as zinc, brass and energy costs) and our ability to pass those costs on to our customers or offset them with reductions in other operating costs,

• Price and product competition from low-cost manufacturing sources (such as China),

• The impact of pricing and production decisions,

• Customer and competitor strategies including substitute products,

• Uncertainties associated with the development of new product features,

• Future litigation,

• Potential difficulties in integrating future acquisitions,

• Decisions to sell operating assets other than in the ordinary course of business,

• Environmental matters (such as those requiring emission and discharge standards for existing and new facilities),

- 2 -

• The ultimate outcome of income tax audits, tax settlement initiatives or other tax matters, including future tax reform,

• The impact of current or future government regulations (including employee healthcare benefit related regulations),

• General global economic and political conditions that introduce instability into the U.S. economy (such as changes in the level of gross domestic product in various regions of the world),

• Operating interruptions (including, but not limited to labor disputes, hazardous chemical leaks, natural disasters, fires, explosions, unscheduled or unplanned downtime, transportation interruptions and cyber attacks); and

• Possible disruption of our business or increases in the cost of doing business resulting from terrorist activities or global conflicts.

Should one or more of these risks materialize or if the consequences worsen, or if the underlying assumptions prove incorrect, actual results could differ materially from those currently forecasted or expected.  We disclaim any intention or obligation to update or revise any forward-looking statement whether as a result of changes in information, future events or otherwise.

Industry Overview

We manufacture engineered components utilized in a variety of applications and industries. We manufacture mechanical and electrical cabinet locks and other locking mechanisms used in the recreational transportation, postal, office and institutional furniture, cabinetry, tool storage and healthcare applications. We also manufacture stainless steel exhaust systems, gauges, throttle controls and trim tabs for the recreational marine and other industries. 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.  See also Item 6 – “Selected Financial Data” and Item 7 – “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Business Segments

We currently have two operating business segments – Security Products and Marine Components.  For additional information regarding our segments, see “Part II – Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Note 2 to the Consolidated Financial Statements.

Manufacturing, Operations and Products

Security Products.Our Security Products segment 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.  Our Security Products segment has one manufacturing facility in Mauldin, South Carolina and one in Grayslake, Illinois shared with Marine Components.  We believe we are a North American market leader in the manufacture and sale of cabinet locks and other locking mechanisms.  These products include:

• disc tumbler locks which provide moderate security and generally represent the lowest cost lock to produce;

• pin tumbler locking mechanisms which are more costly to produce and are used in applications requiring higher levels of security, including KeSet^® and System 64^® (which each allow the user to change the keying on a single lock 64 times without removing the lock from its enclosure), TuBar^® and Turbine™; and

• our innovative CompX eLock^® and StealthLock^® electronic locks which provide stand-alone or networked security and audit trail capability for drug storage and other valuables through the use of a proximity card, magnetic stripe or keypad credentials.

- 3 -

A substantial portion of our Security Products’ sales consist of products with specialized adaptations to an individual customer’s specifications, some of which are listed above.  We also have 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 our STOCK LOCKS^® distribution program.

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

• original equipment and aftermarket stainless steel exhaust headers, exhaust pipes, mufflers and other exhaust components;

• high performance gauges such as GPS speedometers and tachometers;

• mechanical and electronic controls and throttles;

• steering wheels, trim tabs and other billet aluminum accessories; and

• dash panels, LED lighting, wire harnesses and other accessories.

For information regarding our three manufacturing and other facilities, see “Item 2 – Properties,” including information regarding leased and distribution-only facilities.

Raw Materials

Our primary raw materials are:

• zinc and brass (used in the Security Products segment for the manufacture of locking mechanisms); and

• stainless steel (used primarily in the Marine Components segment for the manufacture of exhaust headers and pipes), aluminum (used for the manufacture of throttles and trim tabs), and other components.

These raw materials are purchased from several suppliers, are readily available from numerous sources and accounted for approximately 11% of our total cost of sales for 2017. Total material costs, including purchased components, represented approximately 44% of our cost of sales in 2017.

We occasionally enter into short-term commodity-related raw material supply arrangements to mitigate the impact of future price increases in commodity-related raw materials, including zinc, brass and stainless steel.  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. During 2016 and 2017, markets for the primary commodity-related raw materials used in the manufacture of our locking mechanisms, primarily zinc and brass, generally strengthened, resulting in price increases that exceeded general inflation rates. In the case of zinc, our purchases late in 2017 bore unit costs over 50% higher than those acquired two years earlier. Over that same period, the market for stainless steel, the primary raw material used for the manufacture of marine exhaust headers and pipes, remained relatively stable. While we expect the markets for our primary commodity-related raw materials to stabilize during 2018, we recognize that strengthening economic conditions may exert upward price pressure on these and other manufacturing materials. When purchased on the spot market, each of these raw materials may be subject to sudden and unanticipated 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 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

We hold a number of patents relating to our component products, certain of which we believe to be important to us and our continuing business activity.  Patents generally have a term of 20 years, and our patents have remaining terms ranging from less than 1 year to 17 years at December 31, 2017.  

Our major trademarks and brand names in addition to CompX^® include:

Security Products	Security Products	Marine Components
CompX® Security Products™ National Cabinet Lock® Fort Lock® Timberline® Lock Chicago Lock® STOCK LOCKS® KeSet® TuBar® StealthLock® ACE® ACE® II CompX eLock®	Lockview® System 64® SlamCAM® RegulatoR® CompXpress® GEM®	CompX Marine® Custom Marine® Livorsi® Marine Livorsi II® Marine CMI Industrial® Custom Marine® Stainless Exhaust The #1 Choice in Performance Boating® Mega Rim® Race Rim® Vantage View® GEN-X®

Sales, Marketing and Distribution

A majority of our component sales are direct 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 our 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 segments of the marketplace.  These products are packaged and merchandised for easy availability and handling by distributors and end users.

We sell to a diverse customer base with only one customer representing 10% or more of our sales in 2017 (United States Postal Service representing 16%).  Our largest ten customers accounted for approximately 44% of our sales in 2017.

Competition

The markets in which we participate are highly competitive.  We compete 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.  We focus our efforts on the middle and high-end segments of the market, where product design, quality, durability and service are valued by the customer.  Our Security Products segment competes against a number of domestic and foreign manufacturers.  Our Marine Components segment competes with small domestic manufacturers and is minimally affected by foreign competitors.

Regulatory and Environmental Matters

Our operations are subject to federal, state and local 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”).  Our operations also are subject to federal, state and local laws and regulations relating to worker health and safety.  We believe we are 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.  We currently do not anticipate any significant costs

- 5 -

or expenses relating to such matters; however, it is possible future laws and regulations may require us to incur significant additional expenditures.

Employees

As of December 31, 2017, we employed 520 people, all in the United States.  We believe our labor relations are good at all of our facilities.

Available Information

Our fiscal year end is always the Sunday closest to December 31, and our operations are reported on a 52 or 53-week fiscal year.  We furnish our stockholders 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.  We also make our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and all related amendments, available free of charge through our website at www.compx.com as soon as reasonably practical after they have been filed with the SEC.  We also provide to anyone, without charge, copies of the documents upon written request.  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 also be found on our website.  Information contained on our website is not a part of this Annual Report.

ITEM 1A. RISK FACTORS

Listed below are certain risk factors associated with us and our businesses.  In addition to the potential effect of these risk factors discussed below, 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 operate in mature and highly competitive markets, resulting in pricing pressure and the need to continuously reduce costs.

Many of the markets we serve are highly competitive, with a number of competitors offering similar products.  We focus our efforts on the middle and high-end segment 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.

• Competitors may be able to drive down prices for our products beyond our ability to adjust costs because their costs are lower than ours, especially products sourced from Asia.

• Competitors’ financial, technological and other resources may be greater than our resources, which may enable them to more effectively withstand changes in market conditions.

• Competitors may be able to respond more quickly than we can to new or emerging technologies and changes in customer requirements.

• Consolidation of our competitors or customers in any of the markets in which we compete may result in reduced demand for our products.

- 6 -

• A reduction of our market share with one or more of our key customers, or a reduction in one or more of our key customers’ market share for their end-use products, may reduce demand for our products.

• New competitors could emerge by modifying their existing production facilities to manufacture products that compete with our products.

• We may not be able to sustain a cost structure that enables us to be competitive.

• Customers may no longer value our product design, quality or durability over the lower cost products of our competitors.

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

Historically, our ability to provide value-added custom engineered products that address requirements of technology and space utilization has been a key element of our success.  We spend 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 (“GAAP”), 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 our 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 we introduce will achieve the same degree of success that we have achieved with our 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 we attempt to introduce new product features in the future, we do not know if we will be able to increase production volumes without encountering these or other problems, which might negatively impact our financial condition or results of operations.

Higher costs of our commodity-related raw materials may decrease our liquidity.

Certain raw materials used in our 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.  We occasionally enter 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 be otherwise 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.

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

We rely on patent, trademark and trade secret laws in the United States and similar laws in other countries to establish and maintain our 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.

- 7 -

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 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.

All of our production facilities are located in the United States and we believe all of our production facilities are in substantial compliance with applicable environmental laws.  To date, legislation and regulatory actions related to climate change have not had a material adverse effect on our financial results.  However, if new legislation or regulatory actions related to climate change were to be enacted or implemented, it could negatively impact our future results from operations through increased costs of production, particularly as it relates to our energy requirements.  If such increased costs of production were to materialize, we may be unable to pass price increases on to our customers to compensate for increased production costs, which may decrease our liquidity, operating income and results of operations.

Technology failures or cyber security breaches could have a material adverse effect on our operations.

We rely on information technology systems to manage, process and analyze data, as well as to facilitate the manufacture and distribution of our products to and from our plants.  We receive, process and ship orders, manage the billing of and collections from our customers, and manage the accounting for and payment to our vendors. Although we have systems and procedures in place to protect our information technology systems, there can be no assurance that such systems and procedures would be sufficiently effective. Therefore, any of our information technology systems may be susceptible to outages, disruptions, or destruction as well as cyber security breaches or attacks, resulting in a disruption of our business operations, injury to people, harm to the environment or our assets, and/or the inability to access our information technology systems. If any of these events were to occur, our results of operations and financial condition could be adversely affected.

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

Business Overview

We are a leading manufacturer of engineered components utilized in a variety of applications and industries.  Through our Security Products segment we manufacture mechanical and electrical cabinet locks and other locking mechanisms used in recreational transportation, postal, office and institutional furniture, cabinetry, tool storage and healthcare applications.  We also manufacture stainless steel exhaust systems, gauges, throttle controls and trim tabs for the recreational marine and other industries through our Marine Components segment.

Operating Income Overview

We reported operating income of $15.2 million in 2017 compared to operating income of $15.6 million in 2016 and $14.0 million in 2015.  Operating income in 2017 was comparable to operating income in 2016. The increase in operating income from 2015 to 2016 primarily resulted from a favorable customer and product mix at Security Products, in addition to higher sales and continued margin improvement for Marine Components.

Our product offerings consist of a large number of products that have a wide variation in selling price and manufacturing cost, which results in certain practical limitations on our ability to quantify the impact of changes in individual product sales quantities and selling prices on our net sales, cost of goods sold and gross profit.  In addition, small variations in period-to-period net sales, cost of goods sold and gross profit can result from changes in the relative mix of our products sold.

Critical Accounting Policies and Estimates

We have based the accompanying “Management’s Discussion and Analysis of Financial Condition and Results of Operations” upon our Consolidated Financial Statements.  We prepared our Consolidated Financial Statements in accordance with GAAP.  In preparing our Consolidated Financial Statements, we are required 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 on-going basis, we evaluate our estimates, including those related to inventory reserves, the recoverability of long-lived assets (including goodwill and other intangible assets) and the realization of deferred income tax assets.  We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the reported amounts of assets, liabilities, revenues and expenses.  Our actual future results might differ from previously estimated amounts under different assumptions or conditions.

We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our Consolidated Financial Statements and are applicable to all of our operating segments:

• Goodwill – Our goodwill totaled $23.7 million at December 31, 2017.  We perform a goodwill impairment test annually in the third quarter of each year.  Goodwill is also evaluated for impairment at other times whenever an event occurs or circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying value.  All of our net consolidated goodwill at December 31, 2017 is related to our Security Products segment. In 2017, we used the qualitative assessment of ASC 350-20-35 for our annual impairment test and determined it was not necessary to perform the quantitative goodwill impairment test, as we concluded it is more-likely-than-not that the fair value of the Security Products reporting unit exceeded its carrying amount. See Notes 1 and 5 to the Consolidated Financial Statements.  

When performing a qualitative assessment considerable management judgment is necessary to evaluate the qualitative impact of events and circumstances on the fair value of a reporting unit.  Events and circumstances considered in our impairment evaluations, such as historical profits and stability of the markets served, are consistent with factors utilized with our internal projections and operating plan.  

- 13 -

However, future events and circumstances could result in materially different findings which could result in the recognition of a material goodwill impairment.

• Long-lived assets – We assess property and equipment for impairment only when circumstances (as specified in ASC 360-10-35, Property, Plant, and Equipment) indicate an impairment may exist.  Our determination is based upon, among other things, our estimates of the amount of future net cash flows to be generated by the long-lived asset (Level 3 inputs) and our estimates of the current fair value of the asset.  

Significant judgment is required in estimating such cash flows.  Adverse changes in such estimates of future net cash flows or estimates of fair value could result in an inability to recover the carrying value of the long-lived asset, thereby possibly requiring an impairment charge to be recognized in the future.  We do not assess our property and equipment for impairment unless certain impairment indicators specified in ASC Topic 360-10-35 are present.  We did not evaluate any long-lived assets for impairment during 2017 because no such impairment indicators were present.

Net Sales. Net sales increased approximately $3.1 million in 2017 compared to 2016 primarily due to higher Security Products sales volumes to government security, electronic lock and other markets, partially offset by a decrease in sales of security products to an original equipment manufacturer of recreational transportation products. Marine Components also contributed with higher sales, primarily to the waterski/wakeboard boat market. Relative changes in selling prices did not have a material impact on net sales comparisons.

Net sales for 2016 were comparable to 2015 because our Security Products segment was able to substantially replace revenue for a government security end-user project which did not recur in 2016 with a new project with the same customer. Marine Components also contributed with higher sales to the waterski/wakeboard boat market.  Relative changes in selling prices did not have a material impact on net sales comparisons.

Cost of Goods Sold and Gross Profit.  Cost of goods sold increased from 2016 to 2017 primarily due to increased sales volumes for both the Security Products and Marine Components segments, and to a lesser extent higher raw material prices (mostly zinc and brass) and increased employee medical costs.  Gross profit dollars in 2017 were comparable to 2016. As a percentage of sales, gross profit for 2017 decreased compared to 2016 due primarily to unfavorable relative changes in customer and product mix, higher raw material prices and increased employee medical costs in the Security Products segment, as well as higher manufacturing costs for the Marine Components segment.

- 14 -

Cost of goods sold for 2016 was down from 2015 on comparable sales, resulting in an increase in gross profit. As a percentage of sales, gross profit for 2016 was favorable to 2015 due primarily to higher variable margins resulting from favorable customer and product mix for both Security Products and Marine Components.

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 business unit and corporate management activities, as well as gains and losses on plant, property and equipment.  Operating costs and expenses were comparable in 2015, 2016 and 2017 on an absolute basis and as a percentage of sales.

Operating Income. As a percentage of net sales, operating income decreased slightly from 2016 to 2017 while operating income increased slightly from 2015 to 2016.  Operating margins were primarily impacted by the factors impacting cost of goods sold, gross margin and operating costs discussed above.  

General. Our 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 44% of our cost of sales in 2017, with commodity-related raw materials accounting for approximately 11% of our cost of sales. During 2016 and 2017, markets for the primary commodity-related raw materials used in the manufacture of our locking mechanisms, primarily zinc and brass, generally strengthened, resulting in price increases that exceeded general inflation rates. In the case of zinc, our purchases late in 2017 bore unit costs over 50% higher than those acquired two years earlier. The rapid rise in prices for zinc and brass increased our 2017 aggregate purchase cost for these materials by approximately $0.5 million. Over that same period, the market for stainless steel, the primary raw material used for the manufacture of marine exhaust headers and pipes, remained relatively stable. While we expect the markets for our primary commodity-related raw materials to stabilize during 2018, we recognize that anticipated strengthening economic conditions may exert upward price pressure on these and other manufacturing materials.

We occasionally enter 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.”

  Interest Income. Interest income in 2017 increased compared to 2016 due to higher average balances on our loan to an affiliate (originated late in 2016) and to a lesser extent higher interest rates in 2017. See Note 9 to the Consolidated Financial Statements.

Provision for income taxes. A tabular reconciliation of our actual tax provision to the U.S. federal statutory income tax rate of 35% is included in Note 7 to the Consolidated Financial Statements.  As a member of the group of companies consolidated for U.S. federal income tax purposes with Contran, the parent of our consolidated U.S. federal income tax group, we compute our provision for income taxes on a separate company basis, using the tax elections made by Contran.

Our effective income tax rate was 35% in 2015 and 2016 and 23% in 2017.  Our effective income tax rate in 2016 was comparable to our effective tax rate in 2015.  Our effective income tax rate was lower in 2017 as compared to 2016 as a result of tax reform legislation signed on December 22, 2017 that lowered the U.S. statutory tax rate from 35% to 21% for tax years beginning after December 31, 2017.  H.R.1, formally known as the “Tax Cuts and Jobs Act” (“2017 Tax Act”) was enacted into law on December 22, 2017. This new tax legislation, among other changes, reduces the federal corporate income tax rate from 35% to 21% effective January 1, 2018, eliminates the domestic production activities deduction and allows for the expensing of certain capital expenditures.  Following the enactment of the 2017 Tax Act, the Securities and Exchange Commission issued Staff Accounting Bulletin (SAB) 118 to provide guidance on the accounting and reporting impacts of the 2017 Tax Act.  SAB 118 states that companies should account for changes related to the 2017 Tax Act in the period of enactment if all information is available and the accounting can be completed. In situations where companies do not have enough information to complete the accounting in the period of enactment, a company must either 1) record an estimated provisional amount if the impact of the change can be reasonably estimated; or 2) continue to apply the accounting guidance that was in effect immediately prior to the 2017 Tax Act if the impact of the change cannot be reasonably estimated.  If estimated provisional amounts are recorded,

- 15 -

SAB 118 provides a measurement period of no longer than one year during which companies should adjust those amounts as additional information becomes available.

Under GAAP, we are required to revalue our net deferred tax liability associated with our net taxable temporary differences in the period in which the new tax legislation is enacted based on deferred tax balances as of the enactment date, to reflect the effect of such reduction in the corporate income tax rate.  Our temporary differences as of December 31, 2017 are not materially different from our temporary differences as of the enactment date. Accordingly, revaluation of our net taxable temporary differences is based on our net deferred tax liability as of December 31, 2017. Such revaluation resulted in a non-cash deferred income tax benefit of $1.9 million recognized in continuing operations, reducing our net deferred tax liability.  See Notes 7 and 10 to the Consolidated Financial Statements.  We currently expect our effective income tax rate for 2018 to be approximately 25%, reflecting the reduction in the U.S. statutory tax rate from 35% to 21% and the elimination of the domestic production activities deduction for tax years beginning after December 31, 2017.The amounts recorded as of December 31, 2017 as a result of the 2017 Tax Act represent estimates based on information currently available and, in accordance with the guidance in SAB 118, these amounts are provisional and subject to adjustment as we obtain additional information and complete our analysis in 2018.  If the underlying guidance or tax laws change and such change impacts the income tax effects of the new legislation recognized at December 31, 2017, or we determine we have additional tax liabilities under other provisions of the 2017 Tax Act, we will recognize an adjustment in the reporting period within the measurement period, which period ends December 22, 2018, in which such adjustment is determined.

Segment Results

The key performance indicator for our segments is the level of their operating income (see discussion below).  For additional information regarding our segments refer to Note 2 to the Consolidated Financial Statements.

Security Products.  Security Products net sales increased 2% to $96.6 million in 2017 compared to $94.7 million in 2016, as improved sales to government security, electronic lock and other markets more than offset a decrease of approximately $2.9 million in sales to a customer serving the recreational transportation market. As a percentage of sales, gross profit for 2017 decreased compared to 2016 primarily due to unfavorable relative changes in customer and product mix, and to a lesser extent higher raw material prices (mostly zinc and brass) and increased

- 16 -

employee medical costs.  Operating costs and expenses for 2017 were comparable to 2016.  As a result, Security Products operating income as a percentage of net sales for 2017 was below 2016.

Security Products net sales decreased 1% to $94.7 million in 2016 compared to $95.6 million in 2015. Sales for 2015 included approximately $6.3 million for a government security end-user project which did not recur in 2016. During the second half of 2016, we were awarded a substantial new project for the same customer which began to ship in August and was completed in December 2016, totaling $5.8 million in net sales. Gross profit margins for 2016 increased compared to 2015 on favorable variable margins resulting from relative changes in product and customer mix particularly in the fourth quarter. Operating costs and expenses for 2016 were comparable to 2015. Security Products operating income as a percentage of net sales for 2016 increased compared to 2015 primarily as a result of the factors impacting gross profit and operating costs and expenses discussed above.

Marine Components.  Marine Components net sales increased 8% in 2017 as compared to 2016 as a result of continued strong demand for our products, particularly those sold to the ski/wakeboard boat market. Gross profit margin and operating income as a percentage of net sales decreased in 2017 compared to 2016 principally due to unfavorable relative changes in customer and product mix and higher manufacturing costs, including the impact of personnel turnover in key manufacturing departments.

Marine Component sales increased 6% in 2016 over 2015 primarily due to improved demand for products sold to the ski/wakeboard boat market, including the continuing introduction of new product lines to that market.  As a percentage of net sales, gross margin and the operating income percentage 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.

Outlook

The strong demand for our products in 2017, like the previous two years, was supported by continued high demand from existing customers for government security applications, as well as continued growth in electronic lock sales.  In 2017, the impact of strong demand for these products was somewhat offset by lower sales to the transportation market, where a significant customer of the segment experienced weakened sales in 2017, which is expected to continue into 2018. We also continue to benefit from innovation and diversification in our product offerings to the recreational boat markets served by our Marine Components segment. In 2018, we will seek to capitalize on positive momentum in each of our business segments and on generally improving economic conditions to grow sales and profitability. We will continue to monitor 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.

Liquidity and Capital Resources

Summary

Our primary source of liquidity on an on-going basis is our cash flow from operating activities, which is generally used to (i) fund capital expenditures, (ii) repay short-term or long-term indebtedness incurred primarily for capital expenditures, business combinations or buying back shares of our outstanding stock and (iii) provide for the payment of dividends (if declared).  From time-to-time, we may incur indebtedness to fund capital expenditures, business combinations or other investment activities.  In addition, from time-to-time, we may also sell assets outside the ordinary course of business, the proceeds of which are generally used to repay indebtedness (including indebtedness which may have been collateralized by the assets sold) or to fund capital expenditures or business combinations.

Consolidated cash flows

Operating activities.  Trends in cash flows from operating activities, excluding changes in assets and liabilities, for the last three years have generally been similar to the trends in our earnings.  Depreciation and amortization was comparable in each of 2017, 2016 and 2015. See Note 1 to the Consolidated Financial Statements.

Changes in assets and liabilities result primarily from the timing of production, sales and purchases.  Such changes in assets and liabilities generally tend to even out over time.  However, year-to-year relative changes in assets and liabilities can significantly affect the comparability of cash flows from operating activities.  Cash provided by operating activities was $12.6 million in 2017 compared to $13.9 million in 2016.  The $1.3 million decrease in cash provided by operating activities is primarily the net result of:

• Lower operating income of $0.4 million in 2017,

• Higher interest income received of $1.5 million in 2017,

• Higher cash paid for taxes of $2.1 million in 2017 due to the relative timing of payments and increased profits, and

• A higher amount of net cash used by relative changes in inventories, receivables, payables and non-tax accruals of $0.3 million.

Cash provided by operating activities was comparable in 2016 and 2015 at $13.9 million and $13.5 million, respectively, as higher operating income of $1.6 million in 2016 was offset by a higher amount of net cash used by relative changes in inventories, receivables, payables and non-tax accruals of $1.9 million.

Relative changes in working capital can have a significant effect on cash flows from operating activities.  As shown below, our total average days sales outstanding increased from December 31, 2016 to December 31, 2017 primarily as a result of the timing of sales and collections in the last month of 2017 as compared to 2016.  For comparative purposes, we have provided 2015 numbers below.

Days Sales Outstanding:	December 31, 2015	December 31, 2016	December 31, 2017
Security Products	32 Days	36 Days	39 Days
Marine Components	26 Days	33 Days	31 Days
Total	31 Days	36 Days	38 Days

- 18 -

As shown below, our average number of days in inventory at December 31, 2017 is comparable to December 31, 2016. The variability in days in inventory among our segments primarily relates to the complexity of the production processes, and therefore the length of time it takes to produce end products, as well as seasonal cycles.  For comparative purposes, we have provided 2015 numbers below.

Days in Inventory:	December 31, 2015	December 31, 2016	December 31, 2017
Security Products	70 Days	73 Days	76 Days
Marine Components	120 Days	122 Days	96 Days
Total	76 Days	79 Days	79 Days

Investing activities.  Capital expenditures have primarily emphasized improving our manufacturing facilities and investing in manufacturing equipment, utilizing new technologies and increased automation of the manufacturing process, to provide for increased productivity and efficiency in order to meet expected customer demand and properly maintain our facilities and technology infrastructure.  Capital expenditures were $4.2 million in 2015, $3.2 million in 2016 and $2.8 million in 2017.  See Note 2 to our Consolidated Financial Statements.  Capital expenditures in 2015 and 2016 include approximately $0.5 million and $1.0 million, respectively, for an expansion to our Grayslake facility which was completed in April 2016.    

Capital expenditures for 2018 are estimated at approximately $3.8 million primarily to maintain and improve the cost-effectiveness of our facilities and equipment.  Capital spending for 2018 is expected to be funded through cash on hand and cash generated from operations.

In August 2016, we entered into an unsecured revolving demand promissory note with Valhi whereby we have agreed to loan Valhi up to $40 million.  Our loan to Valhi bears interest at prime rate plus 1.00%, payable quarterly, with all principal due on demand, but in any event no earlier than December 31, 2019.  Loans made to Valhi at any time under the agreement is at our discretion.  During the third and fourth quarters of 2016, Valhi had borrowed a net $27.4 million under the promissory note ($36.6 million of gross borrowings and $9.2 million of gross repayments).  During 2017, Valhi had borrowed a net $10.8 million under the promissory note for an outstanding balance of $38.2 million at December 31, 2017 ($52.1 million of gross borrowings and $41.3 million of gross repayments). See Note 9 to the Consolidated Financial Statements.

Financing activities.  Cash dividends paid totaled $2.5 million ($.20 per share) in each of 2015, 2016 and 2017.

Future Cash Requirements

We believe cash generated from operations together with cash on hand will be sufficient to meet our liquidity needs for working capital, capital expenditures, debt service and dividends (if declared) for the next twelve months and our long term obligations for the next five years.  To the extent that actual operating results or other developments differ materially from our expectations, our liquidity could be adversely affected.

All of our $29.7 million aggregate cash and cash equivalents at December 31, 2017 were held in the U.S.

We periodically evaluate our liquidity requirements, alternative uses of capital, capital needs and available resources in view of, among other things, our capital expenditure requirements, dividend policy and estimated future operating cash flows.  As a result of this process, we have in the past and may in the future seek to raise additional capital, refinance or restructure indebtedness, issue additional securities, repurchase shares of our common stock, modify our dividend policy or take a combination of such steps to manage our liquidity and capital resources.  In the normal course of business, we may review opportunities for acquisitions, joint ventures or other business combinations in the component products industry.  In the event of any such transaction, we may consider using available cash, issuing additional equity securities or increasing our indebtedness or that of our subsidiaries.

Off balance sheet financing arrangements  

Other than certain operating leases discussed in Note 10 to the Consolidated Financial Statements, neither we nor any of our subsidiaries or affiliates are parties to any off-balance sheet financing arrangements.

Commitments and contingencies

As more fully described in the notes to the Consolidated Financial Statements, we are a party to various leases and other agreements that contractually and unconditionally commit us to pay certain amounts in the future.  See Note 10 to the Consolidated Financial Statements.  The following table summarizes such contractual commitments as of December 31, 2017 by the type and date of payment.

	Payments due by period
	Total		2018		2019–2020		2021–2022		2023 and after

Fixed asset acquisitions		397		397		-		-		-
Total contractual cash obligations	$	10,507	$	9,994	$	460	$	53	$	-

The timing and amount shown for our commitments related to operating leases and fixed asset acquisitions are based upon the contractual payment amount and the contractual payment date for those commitments.  The timing and amount shown for purchase obligations, which consist of all open purchase orders and contractual obligations (primarily commitments to purchase raw materials) is also based on the contractual payment amount and the contractual payment date for those commitments.  The amount shown for income taxes is the consolidated amount of income taxes payable at December 31, 2017, which is assumed to be paid during 2018.  Fixed asset acquisitions include firm purchase commitments for capital projects.  

Recent accounting pronouncements

See Note 12 to the Consolidated Financial Statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

General.  We are exposed to market risk from changes in raw materials prices.

Raw materials.  We will occasionally enter into short term commodity-related raw material supply arrangements to mitigate the impact of future increases in commodity-related raw material costs.  We do not have long-term supply agreements for our raw material requirements because either we believe the risk of unavailability of those raw materials is low and we believe the downside risk of price volatility to be too great or because long-term supply agreements for those materials are generally not available.  We do not engage in commodity raw material hedging programs.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures. We maintain disclosure controls and procedures which, as defined in Exchange Act Rule 13a-15(e), means controls and other procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit to the SEC under the Securities Exchange Act of 1934, as amended (the “Act”), is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information we are required to disclose in the reports that we file or submit to the SEC under the Act is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions to be made regarding required disclosure. Our management with the participation of Scott C. James, our President and Chief Executive Officer, and James W. Brown, our Vice President, Chief Financial Officer and Controller, has evaluated the design and operating effectiveness of our disclosure controls and procedures as of December 31, 2017. Based upon their evaluation, these executive officers have concluded that our disclosure controls and procedures are effective as of the date of such evaluation.

Management’s Report on Internal Control Over Financial Reporting.  Our management is responsible for establishing and maintaining adequate internal control over financial reporting which, as defined in Exchange Act Rule 13a-15(f), means a process designed by, or under the supervision of, our principal executive and principal financial officers, or persons performing similar functions, and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles (“GAAP”), and includes those policies and procedures that:

• Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets,

• Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures are being made only in accordance with authorizations of our management and directors, and

• Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our consolidated financial statements.

Our evaluation of the effectiveness of our internal control over financial reporting is based upon the framework established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013 (commonly referred to as the “2013 COSO” framework).  Based on our evaluation under that framework, our management has concluded that our internal control over financial reporting was effective as of December 31, 2017.

This annual report does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting.  Management’s report was not subject to attestation by our registered public accounting firm pursuant to rules of the SEC that permit us to provide only management’s report in this annual report.

Changes in Internal Control Over Financial Reporting.  There have been no changes in our internal control over financial reporting during the quarter ended December 31, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Certifications.  Our chief executive officer and chief financial officer are required to, among other things, quarterly file a certification with the SEC regarding the quality of our public disclosures, as required by Section 302 of the Sarbanes-Oxley Act of 2002.  We have filed the certifications for the quarter ended December 31, 2017 as exhibits 31.1 and 31.2 to this Annual Report on Form 10-K.

Report of Independent Registered Public Accounting Firm

TotheBoard of Directors and Stockholders of CompX International Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of CompX International Inc. and its subsidiaries as of December 31, 2017 and January 1, 2017, and the related consolidated statements of income, stockholders’ equity and cash flowsfor each of the three years in the period ended December 31, 2017, including the related notes (collectively referred to as the “consolidatedfinancial statements”).  In our opinion, the consolidatedfinancial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and January 1, 2017, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2017in conformity with accounting principles generally accepted in the United States of America.  

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management.  Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits.  We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB.  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud.  The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting.  Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks.  Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements.  Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.  We believe that our audits provide a reasonable basis for our opinion.

COMPX INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2017

Note 1 – Summary of significant accounting policies:

Organization.We (NYSE MKT: CIX) are 87% owned by NL Industries, Inc. (NYSE: NL) at December 31, 2017.  We manufacture and sell component products (security products and recreational marine components).  At December 31, 2017, Valhi, Inc. (NYSE: VHI) owns 83% of NL’s outstanding common stock and a wholly-owned subsidiary of Contran Corporation owns 93% of Valhi’s outstanding common stock.  All of Contran’s outstanding voting stock is held by a family trust established for the benefit of Lisa K. Simmons and Serena Simmons Connelly and their children, for which Ms. Simmons and Ms. Connelly are co-trustees, or is held directly by Ms. Simmons and Ms. Connelly or entities related to them.  Consequently, Ms. Simmons and Ms. Connelly may be deemed to control Contran, Valhi, NL and us.  

Unless otherwise indicated, references in this report to “we,” “us,” or “our” refer to CompX International Inc. and its subsidiaries, taken as a whole.

Management estimates.  In preparing our financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at each balance sheet date and the reported amounts of our revenues and expenses during each reporting period.  Actual results may differ significantly from previously estimated amounts under different assumptions or conditions.

Principles of consolidation.  Our consolidated financial statements include the accounts of CompX International Inc. and our wholly-owned subsidiaries.  We eliminate all material intercompany accounts and balances.

Fiscal year.  Our fiscal year end is always the Sunday closest to December 31, and our operations are reported on a 52 or 53-week fiscal year.  The year ended December 31, 2015 consisted of 53 weeks.  Each of the years ended December 31, 2016 and 2017 consisted of 52 weeks.  For presentation purposes, annual and quarterly information in the consolidated financial statements and accompanying notes are presented as ended on March 31, June 30, September 30 and December 31, as applicable. The actual date of our fiscal years ended December 31, 2015, 2016 and 2017 are January 3, 2016, January 1, 2017, and December 31, 2017, respectively.

Cash and cash equivalents.  We classify bank time deposits and government and commercial notes and bills with original maturities of three months or less as cash equivalents.

Net sales.  We record sales when products are shipped and title and other risks and rewards of ownership have passed to the customer, which is generally upon delivery of our products to transport carriers.  Amounts charged to customers for shipping and handling are not material.  Sales are stated net of price, early payment and distributor discounts and volume rebates (none of which are material).  We report any tax assessed by a governmental authority that we collect from our customers that is both imposed on and concurrent with our revenue producing activities (such as sales and use taxes) on a net basis (meaning we do not recognize these taxes either in our revenues or in our costs and expenses). See Note 12.

Accounts receivable.  We provide an allowance for doubtful accounts for known and estimated potential losses arising from our sales to customers based on a periodic review of these accounts.

F-8

Inventories and cost of sales.  We state inventories at the lower of cost or net realizable value. We record a provision for obsolete and slow-moving inventories.  We generally base inventory costs for all inventory categories on average cost that approximates the first-in, first-out method.  Inventories include the costs for raw materials, the cost to manufacture the raw materials into finished goods and overhead.  Depending on the inventory’s stage of completion, our manufacturing costs can include the costs of packing and finishing, utilities, maintenance and depreciation, shipping and handling, and salaries and benefits associated with our manufacturing process.  We allocate fixed manufacturing overhead costs based on normal production capacity.  Unallocated overhead costs resulting from periods with abnormally low production levels are charged to expense as incurred.  As inventory is sold to third parties, we recognize the cost of sales in the same period that the sale occurs.  We periodically review our inventory for estimated obsolescence or instances when inventory is no longer marketable for its intended use, and we record any write-down, equal to the difference between the cost of inventory and its estimated net realizable value, based on assumptions about alternative uses, market conditions and other factors.

Selling, general and administrative expenses; advertising costs.  Selling, general and administrative expenses include costs related to marketing, sales, distribution, research and development and administrative functions such as accounting, treasury and finance, and includes costs for salaries and benefits, travel and entertainment, promotional materials and professional fees.  We expense advertising and research and development costs as incurred.  Advertising costs were not significant in 2015, 2016 or 2017.

Goodwill.  Goodwill represents the excess of cost over fair value of individual net assets acquired in business combinations.  Goodwill is not subject to periodic amortization.  We evaluate goodwill for impairment annually or when circumstances indicate the carrying value may not be recoverable.  See Note 5.

Property and equipment; depreciation expense.  We state property and equipment, including purchased computer software for internal use, at cost.  We compute depreciation of property and equipment for financial reporting purposes principally by the straight-line method over the estimated useful lives of 15 to 40 years for buildings and 3 to 20 years for equipment and software.  We use accelerated depreciation methods for income tax purposes, as permitted.  Depreciation expense was $3.5 million in 2015 and $3.7 million in each of 2016 and 2017.  Upon sale or retirement of an asset, the related cost and accumulated depreciation are removed from the accounts and any gain or loss is recognized in income currently.  Expenditures for maintenance, repairs and minor renewals are expensed; expenditures for major improvements are capitalized.

We perform impairment tests when events or changes in circumstances indicate the carrying value may not be recoverable.  We consider all relevant factors.  We perform the impairment test by comparing the estimated future undiscounted cash flows associated with the asset to the asset’s net carrying value to determine if impairment exists.

Employee benefit plans.  We maintain various defined contribution plans in which we make contributions based on matching or other formulas.  Defined contribution plan expense approximated $2.4 million in 2015, $2.6 million in 2016 and $2.4 million in 2017.

Self-insurance.  We are partially self-insured for workers’ compensation and certain employee health benefits and self-insured for most environmental issues.  We purchase coverage in order to limit our exposure to any significant levels of workers’ compensation or employee health benefit claims.  We accrue self-insured losses based upon estimates of the aggregate liability for uninsured claims incurred using certain actuarial assumptions followed in the insurance industry and our own historical claims experience.

Income taxes.  We, and our parent NL, are members of the Contran Tax Group.  We have been and currently are a part of the consolidated tax returns filed by Contran for U.S. federal purposes as well as for certain U.S. state jurisdictions.  As a member of the Contran Tax Group, we are jointly and severally liable for the federal income tax liability of Contran and the other companies included in the Contran Tax Group for all periods in which we are included in the Contran Tax Group.  See Note 10.

As a member of the Contran Tax Group, we are a party to a tax sharing agreement which provides that we compute our provision for U.S. income taxes on a separate-company basis.  Pursuant to the tax sharing agreement, we make payments to or receive payments from NL in amounts we would have paid to or received from the U.S.

F-9

Internal Revenue Service or the applicable state tax authority had we not been a member of the Contran Tax Group.  The separate company provisions and payments are computed using the tax elections made by Contran.  We made net cash payments for income taxes to NL of $4.7 million in 2015, $4.6 million in 2016 and $6.7 million in 2017.

Deferred income tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the income tax and financial reporting carrying amounts of assets and liabilities.  Deferred income tax assets and liabilities for each tax-paying jurisdiction in which we operate are netted and presented as either a noncurrent deferred income tax asset or liability, as applicable.  We periodically evaluate our deferred tax assets in the various taxing jurisdictions in which we operate and adjust any related valuation allowance based on the estimate of the amount of deferred tax assets which we believe do not meet the more-likely-than-not recognition criteria.  See Notes 7 and 10.

We record a reserve for uncertain tax positions for tax positions where we believe it is more-likely-than-not our position will not prevail with the applicable tax authorities.  We did not have a reserve for uncertain tax positions in each of 2015, 2016 and 2017.

Note 2 – Business and geographic segments:

Our operating segments are defined as components of our operations about which separate financial information is available that is regularly evaluated by our chief operating decision maker in determining how to allocate resources and in assessing performance.  At December 31, 2017, we had two reportable operating segments – Security Products and Marine Components.  

The Security Products segment, with a facility in South Carolina and a facility shared with Marine Components in Illinois, manufactures locking mechanisms and other security products for sale to the transportation, postal, office and institutional furniture, cabinetry, tool storage, healthcare and other industries.

Our Marine Components segment, with a facility in Wisconsin and a facility shared with Security Products in Illinois, manufactures and distributes stainless steel exhaust systems, gauges and throttle controls primarily for recreational boats.

The chief operating decision maker evaluates segment performance based on segment operating income, which is defined as income before income taxes, exclusive of certain general corporate income and expense items (primarily interest income) and certain non-recurring items (such as gains or losses on the disposition of long-lived assets outside the ordinary course of business).  The accounting policies of the reportable operating segments are the same as those described in Note 1.  Capital expenditures include additions to property and equipment, but exclude amounts attributable to business combinations.

Segment assets are comprised of all assets attributable to the reportable segments.  Corporate assets are not attributable to the operating segments and consist primarily of cash, cash equivalents and note receivable from affiliate.  For geographic information, the point of origin (place of manufacture) for all net sales is the U.S., the point of destination for net sales is based on the location of the customer, and property and equipment are attributable to their physical location.  Intersegment sales are not material.

Note 5 – Goodwill:

We assign goodwill based on reporting unit (as that term is defined in ASC Topic 350-20-20, Goodwill) which corresponds to our operating segments.  All of our net goodwill relates to our Security Products segment and was generated from acquisitions relating to our Security Products segment prior to 2001. We test for goodwill impairment at the reporting unit level.  In accordance with the requirements of ASC Topic 350-20-20, we review goodwill for each of our reporting units for impairment during the third quarter of each year or when circumstances arise that indicate an impairment might be present.

In 2015, 2016 and 2017, our goodwill was tested for impairment only in the third quarter of each year in connection with our annual testing date.  No impairment was indicated as part of such annual reviews of goodwill.  As permitted by GAAP, during 2015 and 2017 we used the qualitative assessment of ASC 350-20-35 for our annual impairment test and determined it was not necessary to perform the quantitative goodwill impairment test.  During 2016, we used the quantitative assessment of ASC 350-20-35 for our annual impairment test using discounted cash flows to determine the estimated fair value of our Security Products reporting unit. Such discounted cash flows are a Level 3 input as defined by ASC 820-10-35.  

Our gross goodwill at December 31, 2017 is $33.6 million.  Prior to 2015, we recorded a $9.9 million goodwill impairment in our Marine Components segment resulting in a net consolidated carrying amount of $23.7 million. There have been no changes in the carrying amount of our goodwill during the past three years.

On December 22, 2017, H.R.1, formally known as the “Tax Cuts and Jobs Act” (“2017 Tax Act”) was enacted into law. This new tax legislation, among other changes, reduces the federal corporate income tax rate from 35% to 21% effective January 1, 2018. Following the enactment of the 2017 Tax Act, the Securities and Exchange Commission issued Staff Accounting Bulletin (SAB) 118 to provide guidance on the accounting and reporting impacts of the 2017 Tax Act.  SAB 118 states that companies should account for changes related to the 2017 Tax Act in the period of enactment if all information is available and the accounting can be completed. In situations where companies do not have enough information to complete the accounting in the period of enactment, a company must either 1) record an estimated provisional amount if the impact of the change can be reasonably estimated; or 2) continue to apply the accounting guidance that was in effect immediately prior to the 2017 Tax Act if the impact of the change cannot be reasonably estimated.  If estimated provisional amounts are recorded, SAB 118 provides a measurement period of no longer than one year during which companies should adjust those amounts as additional information becomes available.

Under GAAP, we are required to revalue our net deferred tax liability associated with our net taxable temporary differences in the period in which the new tax legislation is enacted based on deferred tax balances as of the enactment date, to reflect the effect of the reduction in the corporate income tax rate.  Our temporary differences as of December 31, 2017 are not materially different from our temporary differences as of the enactment date. Accordingly, revaluation of our temporary differences is based on our net deferred tax liability as of December 31, 2017. Such revaluation resulted in a non-cash deferred income tax benefit of approximately $1.9 million, recognized in continuing operations, reducing our net deferred tax liability.  The new tax legislation also eliminated the domestic production activities deduction beginning in 2018 and allows for the expensing of certain capital expenditures for assets placed in service between September 28, 2017 and December 31, 2022. The amounts recorded as of December 31, 2017 as a result of the 2017 Tax Act represent estimates based on information currently available and, in accordance with the guidance in SAB 118, these amounts are provisional and subject to adjustment as we obtain additional information and complete our analysis in 2018.  If the underlying guidance or tax laws change and such change impacts the income tax effects of the new legislation recognized at December 31, 2017, or we determine we have additional tax liabilities under other provisions of the 2017 Tax Act, we will recognize an adjustment in the reporting period within the measurement period, which period ends December 22, 2018, in which such adjustment is determined.

Class A and Class B common stock.  The shares of Class A common stock and Class B common stock are identical in all respects, except for certain voting rights and certain conversion rights in respect of the shares of the Class B common stock.  Holders of Class A common stock are entitled to one vote per share.  NL, which holds all of the outstanding shares of Class B common stock, is entitled to one vote per share in all matters except for election of directors, for which NL is entitled to ten votes per share.  Holders of all classes of common stock entitled to vote will vote together as a single class on all matters presented to the stockholders for their vote or approval, except as otherwise required by applicable law.  Each share of Class A common stock and Class B common stock have an equal and ratable right to receive dividends to be paid from our assets when and if declared by the board of directors.  In the event of the dissolution, liquidation or winding up of our operations, the holders of Class A common stock and Class B common stock will be entitled to share equally and ratably in the assets available for distribution after payments are made to our creditors and to the holders of any of our preferred stock that may be outstanding at the time.  Shares of the Class A common stock have no conversion rights.  Under certain conditions, shares of Class B common stock will convert, on a share-for-share basis, into shares of Class A common stock.

Share repurchases and cancellations.  Prior to 2015, our board of directors authorized various repurchases of shares of our Class A common stock in open market transactions, including block purchases, or in privately-negotiated transactions at unspecified prices and over an unspecified period of time.  We may repurchase our common stock from time to time as market conditions permit.  The stock repurchase program does not include specific price targets or timetables and may be suspended at any time.  Depending on market conditions, we may terminate the program prior to its completion.  We will generally use cash on hand to acquire the shares.  Repurchased shares will

F-15

be added to our treasury and cancelled.  We made no treasury purchases during 2015, 2016 or 2017 and at December 31, 2017, approximately 678,000 shares were available for purchase under these authorizations.

Incentive compensation plan.  We have a share based incentive compensation plan pursuant to which an aggregate of up to 200,000 shares of our common stock can be awarded to non-employee members of our board of directors.  All of the Class A common shares we issued in 2015, 2016 and 2017 were issued under this plan.  At December 31, 2017, 166,000 shares were available for award under this plan.

Dividends.  We paid regular quarterly dividends of $.05 per share during 2015, 2016 and 2017. Declaration and payment of future dividends and the amount thereof, if any, is discretionary and dependent upon our results of operations, financial condition, cash requirements for our businesses, contractual requirements and restrictions and other factors deemed relevant by our board of directors.

Note 9 – Related party transactions:

We may be deemed to be controlled by Ms. Lisa Simmons and Ms. Serena Connelly.  See Note 1.  Corporations that may be deemed to be controlled by or affiliated with these individuals sometimes engage in (a) intercorporate transactions such as guarantees, management and expense sharing arrangements, shared fee arrangements, joint ventures, partnerships, loans, options, advances of funds on open account, and sales, leases and exchanges of assets, including securities issued by both related and unrelated parties and (b) common investment and acquisition strategies, business combinations, reorganizations, recapitalizations, securities repurchases, and purchases and sales (and other acquisitions and dispositions) of subsidiaries, divisions or other business units, which transactions have involved both related and unrelated parties and have included transactions that resulted in the acquisition by one related party of a publicly-held minority equity interest in another related party.  We continuously consider, review and evaluate, and understand that Contran and related entities consider, review and evaluate such transactions.  Depending upon the business, tax and other objectives then relevant, it is possible that we might be a party to one or more such transactions in the future.

From time to time, we may have loans and advances outstanding between us and various related parties pursuant to term and demand notes.  We generally enter into these loans and advances for cash management purposes.  When we loan funds to related parties, we are generally able to earn a higher rate of return on the loan than we would earn if we invested the funds in other instruments.  While certain of these loans may be of a lesser credit quality than cash equivalent instruments otherwise available to us, we believe we have evaluated the credit risks in the terms of the applicable loans.  In this regard, in August 2016, we entered into an unsecured revolving demand promissory note with Valhi whereby we have agreed to loan Valhi up to $40 million.  Our loan to Valhi, as amended, bears interest at prime plus 1.00%, payable quarterly, with all principal due on demand, but in any event no earlier than December 31, 2019.  Loans made to Valhi at any time under the agreement is at our discretion. At December 31, 2016 and 2017, the outstanding principal balance receivable from Valhi under the promissory note was $27.4 million and $38.2 million, respectively.  Interest income (including unused commitment fees) on our loan to Valhi was $0.2 million in 2016 and $1.8 million in 2017.  

Under the terms of an Intercorporate Service Agreement (“ISA”) with Contran, employees of Contran perform certain management, tax planning, financial, legal and administrative services for us on a fee basis.  Such fees are based upon estimates of time devoted to our affairs by individual Contran employees and the compensation of such persons.  Because of the large number of companies affiliated with Contran, we believe we benefit from cost savings and economies of scale gained by not having certain management, financial and administrative staffs duplicated at each entity, thus allowing certain individuals to provide services to multiple companies but only be compensated by one entity.  Fees pursuant to these agreements aggregated $3.0 million in 2015, $3.1 million in 2016 and $2.8 million in 2017.

Contran and certain of its subsidiaries and affiliates, including us, purchase certain of their insurance policies as a group, with the costs of the jointly-owned policies being apportioned among the participating companies.  Tall Pines Insurance Company (“Tall Pines”) and EWI RE, Inc. (“EWI”), each subsidiaries of Valhi, provide for or broker certain insurance policies for Contran and certain of its subsidiaries and affiliates, including us.  Tall Pines purchases reinsurance from third-party insurance carriers with an A.M.  Best Company rating of generally at least A-(Excellent) for substantially all of the risks it underwrites.  Consistent with insurance industry practices, Tall Pines

F-16

and EWI receive commissions from the insurance and reinsurance underwriters and/or assess fees for the policies that they provide or broker.  The aggregate premiums we paid to Tall Pines and EWI were approximately $1.6 million in 2015, $1.7 million in 2016 and $2.2 million in 2017.  These amounts principally represent payments for insurance premiums, which include premiums or fees paid to Tall Pines or fees paid to EWI.  These amounts also include payments to insurers or reinsurers through EWI for the reimbursement of claims within our applicable deductible or retention ranges that such insurers or reinsurers paid to third parties on our behalf, as well as amounts for claims and risk management services and various other third-party fees and expenses incurred by the program.  We expect that these relationships with Tall Pines and EWI will continue in 2018.  

With respect to certain of such jointly-owned insurance policies, it is possible that unusually large losses incurred by one or more insureds during a given policy period could leave the other participating companies without adequate coverage under that policy for the balance of the policy period. As a result, and in the event that the available coverage under a particular policy would become exhausted by one or more claims, Contran and certain of its subsidiaries and affiliates, including us, have entered into a loss sharing agreement under which any uninsured loss arising because the available coverage had been exhausted by one or more claims will be shared ratably amongst those entities that had submitted claims under the relevant policy. We believe the benefits in the form of reduced premiums and broader coverage associated with the group coverage for such policies justifies the risk associated with the potential for any uninsured loss.

Note 10 – Commitments and contingencies:

Legal proceedings.  We are involved, from time to time, in various environmental, contractual, product liability, patent (or intellectual property), employment and other claims and disputes incidental to our business.  We currently believe the disposition of all claims and disputes, individually or in the aggregate, should not have a material long-term adverse effect on our consolidated financial condition, results of operations or liquidity.

Environmental matters and litigation.  Our operations are governed by various federal, state and local environmental laws and regulations.  Our policy is to comply with environmental laws and regulations at all of our facilities and to continually strive to improve environmental performance in association with applicable industry initiatives.  We believe that our operations are in substantial compliance with applicable requirements of environmental laws.  From time to time, we may be subject to environmental regulatory enforcement under various statutes, resolution of which typically involves the establishment of compliance programs.

Income taxes.  From time to time, we undergo examinations of our income tax returns, and tax authorities have or may propose tax deficiencies.  We believe that we have adequately provided accruals for additional income taxes and related interest expense which may ultimately result from such examinations and we believe that the ultimate disposition of all such examinations should not have a material adverse effect on our consolidated financial position, results of operations or liquidity.

We are a party to a tax sharing agreement with Contran and NL providing for the allocation of tax liabilities and tax payments as described in Note 1.  Under applicable law, we, as well as every other member of the Contran Tax Group, are each jointly and severally liable for the aggregate federal income tax liability of Contran and the other companies included in the Contran Tax Group for all periods in which we are included in the Contran Tax Group.  NL has agreed, however, to indemnify us for any liability for income taxes of the Contran Tax Group in excess of our tax liability in accordance with the tax sharing agreement.

Concentration of credit risk.  Our products are sold primarily in North America to original equipment manufacturers.  Our ten largest customers accounted for approximately 48% of sales in 2015, 46% in 2016, and 44% in 2017.  One customer of the Security Products segment accounted for 13% of consolidated sales in 2015, 14% in 2016 and 16% in 2017.  Another customer of the Security Products segment accounted for approximately 12% of consolidated sales in 2015 and 11% in 2016.

F-17

Rent expense was approximately $0.1 million in 2015 and $0.2 million in each of 2016 and 2017. At December 31, 2017, future minimum rentals under non-cancellable operating leases having an initial or remaining term of more than one year were as follows:

Due to their near-term maturities, the carrying amounts of accounts receivable and accounts payable are considered equivalent to fair value.

Note 12 – Recent Accounting Pronouncements:

Adopted

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-04, Intangibles— Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment, which aims to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test.  Previously, Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill.  Instead, under the new ASU, an entity performs its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and a goodwill impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. In no circumstances will the loss recognized exceed the total amount of goodwill allocated to that reporting unit. We elected to adopt this ASU beginning with our goodwill impairment test performed in the third quarter of 2017. The application of ASU 2017-04 did not have a material effect on our Condensed Consolidated Financial Statements.

Pending Adoption

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606).  This standard replaces existing revenue recognition guidance, which in many cases was tailored for specific industries, with a uniform accounting standard applicable to all industries and transactions.  The new standard, as amended, is currently effective for us beginning with the first quarter of 2018.  Entities may elect to adopt ASU No. 2014-09 retrospectively for all periods for all contracts and transactions which occurred during the period (with a few exceptions for practical expediency) or modified retrospectively with a cumulative effect recognized as of the date of adoption.  We will adopt the standard in the first quarter of 2018 including the expanded disclosure requirements using

F-18

the modified retrospective approach to adoption. Our sales generally involve single performance obligations to ship goods pursuant to customer purchase orders without further underlying contracts. Prices for our products are based on published price lists, customer agreements and individual customer orders which do not involve variable consideration, financing components, noncash consideration or consideration paid to our customers.  We currently record sales when products are shipped and title and other risks and rewards of ownership have passed to the customer, which is generally upon delivery of our products to transport carriers.  Under ASU 2014-09, we will record sales when our customers obtain control of our products, which we have determined is also upon delivery of our products to transport carriers, consistent with our current practice.  Accordingly, we expect adoption of this standard will have minimal effect on our revenues and disclosure.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is a comprehensive rewriting of the lease accounting guidance which aims to increase comparability and transparency with regard to lease transactions.   The primary change will be the recognition of lease assets for the right-of–use of the underlying asset and lease liabilities for the obligation to make payments by lessees on the balance sheet for leases currently classified as operating leases.   The ASU also requires increased qualitative disclosure about leases in addition to quantitative disclosures currently required.  Companies are required to use a modified retrospective approach to adoption with a practical expedient which will allow companies to continue to account for existing leases under the prior guidance unless a lease is modified, other than the requirement to recognize the right-of-use asset and lease liability for all operating leases. The changes indicated above will be effective for us beginning in the first quarter of 2019, with early adoption permitted. We have not yet evaluated the effect this ASU will have on our Consolidated Financial Statements, but given the amount of our future minimum payments under non-cancellable operating leases at December 31, 2017 totaling $0.4 million, we do not expect the adoption of this standard to have a material effect on our Consolidated Balance Sheet.

• the aggregate outstanding principal balance does not exceed $40,000,000.00; and

• no Event of Default has occurred and is continuing.

Notwithstanding anything else in this Note, in no event will Noteholder be required to lend money to Borrower under this Note and loans under this Note shall be at the sole and absolute discretion of Noteholder.

Section 6.  Interest.  The unpaid principal balance of this Note shall bear interest at the rate per annum of the Prime Rate plus one percent (1.00%).  In the event that an Event of Default occurs and is continuing, the unpaid

Page 1 of 5.

principal amountshall bear interest from the Event of Default at the rate per annum of the Prime Rateplus four percent (4.00%) until such time as the Event of Default is cured.  Accrued interest on the unpaid principal of this Note shall be computed on the basis of a 365- or 366-day year for actual days (including the first, but excluding the last day) elapsed, but in no event shall such computation result in an amount of accrued interest that would exceed accrued interest on the unpaid principal balance during the same period at the Maximum Rate. Notwithstanding anything to the contrary, this Note is expressly limited so that in no contingency or event whatsoever shall the amount paid or agreed to be paid to the Noteholder exceed the Maximum Rate.  If, from any circumstances whatsoever, the Noteholder shall ever receive as interest an amount that would exceed the Maximum Rate, such amount that would be excessive interest shall be applied to the reduction of the unpaid principal balance and not to the payment of interest, and if the principal amount of this Note is paid in full, any remaining excess shall be paid to Borrower, and in such event, the Noteholder shall not be subject to any penalties provided by any laws for contracting for, charging, taking, reserving or receiving interest in excess of the highest lawful rate permissible under applicable law.  All sums paid or agreed to be paid to Noteholder for the use, forbearance or detention of the indebtedness of the Borrower to Noteholder shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in full of the principal (including the period of any renewal or extension thereof) so that the interest on account of such indebtedness shall not exceed the Maximum Rate.  If at any time the Contract Rate is limited to the Maximum Rate, any subsequent reductions in the Contract Rate shall not reduce the rate of interest on this Note below the Maximum Rate until the total amount of interest accrued equals the amount of interest that would have accrued if the Contract Rate had not been limited by the Maximum Rate.  In the event that, upon the Final Payment Date, the total amount of interest paid or accrued on this Note is less than the amount of interest that would have accrued if the Contract Rate had not been limited by the Maximum Rate, then at such time, to the extent permitted by law, in addition to the principal and any other amounts Borrower owes to the Noteholder, the Borrower shall pay to the Noteholder an amount equal to the difference between:  (i) the lesser of the amount of interest that would have accrued if the Contract Rate had not been limited by the Maximum Rate or the amount of interest that would have accrued if the Maximum Rate had at all times been in effect; and (ii) the amount of interest actually paid on this Note.

Section 7.  Fees and Expenses. On the last day of each March, June, September and December, commencing March 31, 2018, and on the Final Payment Date, Borrower shall pay to Noteholder the Unused Commitment Fee for such period, provided, however, Borrower will not owe any Unused Commitment Fee for any part of such period (prorated as applicable) that the Noteholder is a net borrower of money from the Borrower. In addition, Borrower and any guarantor jointly and severally agree to pay on the Final Payment Date to Noteholder any other cost or expense reasonably incurred by Noteholder in connection with Noteholder’s commitment to Borrower pursuant to the terms of this Note, including without limitation any other cost reasonably incurred by Noteholder pursuant to the terms of any credit facility of Noteholder.

Section 8.  Remedy.  Upon the occurrence and during the continuation of an Event of Default, the Noteholder shall have all of the rights and remedies provided in the applicable Uniform Commercial Code, this Note or any other agreement among Borrower and in favor of the Noteholder, as well as those rights and remedies provided by any other applicable law, rule or regulation.  In conjunction with and in addition to the foregoing rights and remedies of the Noteholder, the Noteholder may declare all indebtedness due under this Note, although otherwise unmatured, to be due and payable immediately without notice or demand whatsoever. All rights and remedies of the Noteholder are cumulative and may be exercised singly or concurrently.  The failure to exercise any right or remedy will not be a waiver of such right or remedy.

Section 9.  Right of Offset.  The Noteholder shall have the right of offset against amounts that may be due by the Noteholder now or in the future to Borrower against amounts due under this Note.

Section 10.  Record of Outstanding Indebtedness.  The date and amount of each repayment of principal outstanding under this Note or interest thereon shall be recorded by Noteholder in its records.  The principal balance outstanding and all accrued or accruing interest owed under this Note as recorded by Noteholder in its records shall be the best evidence of the principal balance outstanding and all accrued or accruing interest owed under this Note; provided that the failure of Noteholder to so record or any error in so recording or computing any such amount owed shall not limit or otherwise affect the obligations of the Borrower under this Note to repay the principal balance outstanding and all accrued or accruing interest.

Section 11.  Waiver.  Borrower and each surety, endorser, guarantor, and other party now or subsequently liable for payment of this Note, severally waive demand, presentment for payment, notice of nonpayment, notice of

Page 2 of 5.

dishonor, protest, notice of protest, notice of the intention to accelerate, notice of acceleration, diligence in collecting or bringing suit against any party liable on this Note, and further agree to any and all extensions, renewals, modifications, partial payments, substitutions of evidence of indebtedness, and the taking or release of any collateral with or without notice before or after demand by the Noteholder for payment under this Note.

Section 12.  Costs and Attorneys’ Fees.  In addition to any other amounts payable to Noteholder pursuant to the terms of this Note, in the event the Noteholder incurs costs in collecting on this Note, this Note is placed in the hands of any attorney for collection, suit is filed on this Note or if proceedings are had in bankruptcy, receivership, reorganization, or other legal or judicial proceedings for the collection of this Note, Borrower and any guarantor jointly and severally agree to pay on demand to the Noteholder all expenses and costs of collection, including, but not limited to, reasonable attorneys’ fees incurred in connection with any such collection, suit, or proceeding, in addition to the principal and interest then due.

Section 13.  Time of Essence.  Time is of the essence with respect to all of Borrower’s obligations and agreements under this Note.

Section 14.  Jurisdiction and Venue.  THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE DOMESTIC LAWS OF THE STATE OF TEXAS, WITHOUT GIVING EFFECT TO ANY CHOICE OF LAW OR CONFLICT OF LAW PROVISION OR RULE (WHETHER OF THE STATE OF TEXAS OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF TEXAS. BORROWER CONSENTS TO JURISDICTION IN THE COURTS LOCATED IN DALLAS, TEXAS.

Section 15.  Notice.  Any notice or demand required by this Note shall be deemed to have been given and received on the earlier of (i) when the notice or demand is actually received by the recipient or (ii) 72 hours after the notice is deposited in the United States mail, certified or registered, with postage prepaid, and addressed to the recipient.  The address for giving notice or demand under this Note (i) to the Noteholder shall be the place of payment specified in Section 3 or such other place as the Noteholder may specify in writing to the Borrower and (ii) to Borrower shall be the address below the Borrower’s signature or such other place as the Borrower may specify in writing to the Noteholder.

Section 16.  Amendment or Waiver of Provisions of this Note.  No amendment or waiver of any provision of this Note shall in any event be effective unless the same shall be in a writing referring to this Note and signed by the Borrower and the Noteholder.  Such amendment or waiver shall be effective only in the specific instance and for the specific purpose for which given.  No waiver of any of the provisions of this Note shall be deemed or shall constitute a waiver of any other provisions, whether or not similar, nor shall any waiver constitute a continuing waiver.

Section 17.  Successors and Assigns.  All of the covenants, obligations, promises and agreements contained in this Note made by Borrower shall be binding upon its successors and permitted assigns, as applicable.  Notwithstanding the foregoing, Borrower shall not assign this Note or its performance under this Note without the prior written consent of the Noteholder.  Noteholder at any time may assign this Note without the consent of Borrower.

Management estimates.  In preparing our financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at each balance sheet date and the reported amounts of our revenues and expenses during each reporting period.  Actual results may differ significantly from previously estimated amounts under different assumptions or conditions.

Principles of consolidation.  Our consolidated financial statements include the accounts of CompX International Inc. and our wholly-owned subsidiaries.  We eliminate all material intercompany accounts and balances.

Fiscal year.  Our fiscal year end is always the Sunday closest to December 31, and our operations are reported on a 52 or 53-week fiscal year.  The year ended December 31, 2015 consisted of 53 weeks.  Each of the years ended December 31, 2016 and 2017 consisted of 52 weeks.  For presentation purposes, annual and quarterly information in the consolidated financial statements and accompanying notes are presented as ended on March 31, June 30, September 30 and December 31, as applicable. The actual date of our fiscal years ended December 31, 2015, 2016 and 2017 are January 3, 2016, January 1, 2017, and December 31, 2017, respectively.

Cash and cash equivalents.  We classify bank time deposits and government and commercial notes and bills with original maturities of three months or less as cash equivalents.

Net sales.  We record sales when products are shipped and title and other risks and rewards of ownership have passed to the customer, which is generally upon delivery of our products to transport carriers.  Amounts charged to customers for shipping and handling are not material.  Sales are stated net of price, early payment and distributor discounts and volume rebates (none of which are material).  We report any tax assessed by a governmental authority that we collect from our customers that is both imposed on and concurrent with our revenue producing activities (such as sales and use taxes) on a net basis (meaning we do not recognize these taxes either in our revenues or in our costs and expenses). See Note 12.

Accounts receivable.  We provide an allowance for doubtful accounts for known and estimated potential losses arising from our sales to customers based on a periodic review of these accounts.

Inventories and cost of sales.  We state inventories at the lower of cost or net realizable value. We record a provision for obsolete and slow-moving inventories.  We generally base inventory costs for all inventory categories on average cost that approximates the first-in, first-out method.  Inventories include the costs for raw materials, the cost to manufacture the raw materials into finished goods and overhead.  Depending on the inventory’s stage of completion, our manufacturing costs can include the costs of packing and finishing, utilities, maintenance and depreciation, shipping and handling, and salaries and benefits associated with our manufacturing process.  We allocate fixed manufacturing overhead costs based on normal production capacity.  Unallocated overhead costs resulting from periods with abnormally low production levels are charged to expense as incurred.  As inventory is sold to third parties, we recognize the cost of sales in the same period that the sale occurs.  We periodically review our inventory for estimated obsolescence or instances when inventory is no longer marketable for its intended use, and we record any write-down, equal to the difference between the cost of inventory and its estimated net realizable value, based on assumptions about alternative uses, market conditions and other factors.

Selling, general and administrative expenses; advertising costs.  Selling, general and administrative expenses include costs related to marketing, sales, distribution, research and development and administrative functions such as accounting, treasury and finance, and includes costs for salaries and benefits, travel and entertainment, promotional materials and professional fees.  We expense advertising and research and development costs as incurred.  Advertising costs were not significant in 2015, 2016 or 2017.

Goodwill.  Goodwill represents the excess of cost over fair value of individual net assets acquired in business combinations.  Goodwill is not subject to periodic amortization.  We evaluate goodwill for impairment annually or when circumstances indicate the carrying value may not be recoverable.  See Note 5.

Property and equipment; depreciation expense.  We state property and equipment, including purchased computer software for internal use, at cost.  We compute depreciation of property and equipment for financial reporting purposes principally by the straight-line method over the estimated useful lives of 15 to 40 years for buildings and 3 to 20 years for equipment and software.  We use accelerated depreciation methods for income tax purposes, as permitted.  Depreciation expense was $3.5 million in 2015 and $3.7 million in each of 2016 and 2017.  Upon sale or retirement of an asset, the related cost and accumulated depreciation are removed from the accounts and any gain or loss is recognized in income currently.  Expenditures for maintenance, repairs and minor renewals are expensed; expenditures for major improvements are capitalized.

We perform impairment tests when events or changes in circumstances indicate the carrying value may not be recoverable.  We consider all relevant factors.  We perform the impairment test by comparing the estimated future undiscounted cash flows associated with the asset to the asset’s net carrying value to determine if impairment exists.

Employee benefit plans.  We maintain various defined contribution plans in which we make contributions based on matching or other formulas.  Defined contribution plan expense approximated $2.4 million in 2015, $2.6 million in 2016 and $2.4 million in 2017.

Self-insurance.  We are partially self-insured for workers’ compensation and certain employee health benefits and self-insured for most environmental issues.  We purchase coverage in order to limit our exposure to any significant levels of workers’ compensation or employee health benefit claims.  We accrue self-insured losses based upon estimates of the aggregate liability for uninsured claims incurred using certain actuarial assumptions followed in the insurance industry and our own historical claims experience.

Income taxes.  We, and our parent NL, are members of the Contran Tax Group.  We have been and currently are a part of the consolidated tax returns filed by Contran for U.S. federal purposes as well as for certain U.S. state jurisdictions.  As a member of the Contran Tax Group, we are jointly and severally liable for the federal income tax liability of Contran and the other companies included in the Contran Tax Group for all periods in which we are included in the Contran Tax Group.  See Note 10.

As a member of the Contran Tax Group, we are a party to a tax sharing agreement which provides that we compute our provision for U.S. income taxes on a separate-company basis.  Pursuant to the tax sharing agreement, we make payments to or receive payments from NL in amounts we would have paid to or received from the U.S. Internal Revenue Service or the applicable state tax authority had we not been a member of the Contran Tax Group.  The separate company provisions and payments are computed using the tax elections made by Contran.  We made net cash payments for income taxes to NL of $4.7 million in 2015, $4.6 million in 2016 and $6.7 million in 2017.

Deferred income tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the income tax and financial reporting carrying amounts of assets and liabilities.  Deferred income tax assets and liabilities for each tax-paying jurisdiction in which we operate are netted and presented as either a noncurrent deferred income tax asset or liability, as applicable.  We periodically evaluate our deferred tax assets in the various taxing jurisdictions in which we operate and adjust any related valuation allowance based on the estimate of the amount of deferred tax assets which we believe do not meet the more-likely-than-not recognition criteria.  See Notes 7 and 10.

We record a reserve for uncertain tax positions for tax positions where we believe it is more-likely-than-not our position will not prevail with the applicable tax authorities.  We did not have a reserve for uncertain tax positions in each of 2015, 2016 and 2017.

Segment Reporting [Abstract]

Business and Geographic Segments

Note 2 – Business and geographic segments:

Our operating segments are defined as components of our operations about which separate financial information is available that is regularly evaluated by our chief operating decision maker in determining how to allocate resources and in assessing performance.  At December 31, 2017, we had two reportable operating segments – Security Products and Marine Components.

The Security Products segment, with a facility in South Carolina and a facility shared with Marine Components in Illinois, manufactures locking mechanisms and other security products for sale to the transportation, postal, office and institutional furniture, cabinetry, tool storage, healthcare and other industries.

Our Marine Components segment, with a facility in Wisconsin and a facility shared with Security Products in Illinois, manufactures and distributes stainless steel exhaust systems, gauges and throttle controls primarily for recreational boats.

The chief operating decision maker evaluates segment performance based on segment operating income, which is defined as income before income taxes, exclusive of certain general corporate income and expense items (primarily interest income) and certain non-recurring items (such as gains or losses on the disposition of long-lived assets outside the ordinary course of business).  The accounting policies of the reportable operating segments are the same as those described in Note 1.  Capital expenditures include additions to property and equipment, but exclude amounts attributable to business combinations.

Segment assets are comprised of all assets attributable to the reportable segments.  Corporate assets are not attributable to the operating segments and consist primarily of cash, cash equivalents and note receivable from affiliate.  For geographic information, the point of origin (place of manufacture) for all net sales is the U.S., the point of destination for net sales is based on the location of the customer, and property and equipment are attributable to their physical location.  Intersegment sales are not material.

Goodwill And Intangible Assets Disclosure [Abstract]

Goodwill

Note 5 – Goodwill:

We assign goodwill based on reporting unit (as that term is defined in ASC Topic 350-20-20, Goodwill) which corresponds to our operating segments.  All of our net goodwill relates to our Security Products segment and was generated from acquisitions relating to our Security Products segment prior to 2001. We test for goodwill impairment at the reporting unit level.  In accordance with the requirements of ASC Topic 350-20-20, we review goodwill for each of our reporting units for impairment during the third quarter of each year or when circumstances arise that indicate an impairment might be present.

In 2015, 2016 and 2017, our goodwill was tested for impairment only in the third quarter of each year in connection with our annual testing date.  No impairment was indicated as part of such annual reviews of goodwill.  As permitted by GAAP, during 2015 and 2017 we used the qualitative assessment of ASC 350-20-35 for our annual impairment test and determined it was not necessary to perform the quantitative goodwill impairment test.  During 2016, we used the quantitative assessment of ASC 350-20-35 for our annual impairment test using discounted cash flows to determine the estimated fair value of our Security Products reporting unit. Such discounted cash flows are a Level 3 input as defined by ASC 820-10-35.  

Our gross goodwill at December 31, 2017 is $33.6 million.  Prior to 2015, we recorded a $9.9 million goodwill impairment in our Marine Components segment resulting in a net consolidated carrying amount of $23.7 million. There have been no changes in the carrying amount of our goodwill during the past three years.

On December 22, 2017, H.R.1, formally known as the “Tax Cuts and Jobs Act” (“2017 Tax Act”) was enacted into law. This new tax legislation, among other changes, reduces the federal corporate income tax rate from 35% to 21% effective January 1, 2018. Following the enactment of the 2017 Tax Act, the Securities and Exchange Commission issued Staff Accounting Bulletin (SAB) 118 to provide guidance on the accounting and reporting impacts of the 2017 Tax Act.  SAB 118 states that companies should account for changes related to the 2017 Tax Act in the period of enactment if all information is available and the accounting can be completed. In situations where companies do not have enough information to complete the accounting in the period of enactment, a company must either 1) record an estimated provisional amount if the impact of the change can be reasonably estimated; or 2) continue to apply the accounting guidance that was in effect immediately prior to the 2017 Tax Act if the impact of the change cannot be reasonably estimated.  If estimated provisional amounts are recorded, SAB 118 provides a measurement period of no longer than one year during which companies should adjust those amounts as additional information becomes available.

Under GAAP, we are required to revalue our net deferred tax liability associated with our net taxable temporary differences in the period in which the new tax legislation is enacted based on deferred tax balances as of the enactment date, to reflect the effect of the reduction in the corporate income tax rate.  Our temporary differences as of December 31, 2017 are not materially different from our temporary differences as of the enactment date. Accordingly, revaluation of our temporary differences is based on our net deferred tax liability as of December 31, 2017. Such revaluation resulted in a non-cash deferred income tax benefit of approximately $1.9 million, recognized in continuing operations, reducing our net deferred tax liability.  The new tax legislation also eliminated the domestic production activities deduction beginning in 2018 and allows for the expensing of certain capital expenditures for assets placed in service between September 28, 2017 and December 31, 2022. The amounts recorded as of December 31, 2017 as a result of the 2017 Tax Act represent estimates based on information currently available and, in accordance with the guidance in SAB 118, these amounts are provisional and subject to adjustment as we obtain additional information and complete our analysis in 2018.  If the underlying guidance or tax laws change and such change impacts the income tax effects of the new legislation recognized at December 31, 2017, or we determine we have additional tax liabilities under other provisions of the 2017 Tax Act, we will recognize an adjustment in the reporting period within the measurement period, which period ends December 22, 2018, in which such adjustment is determined.        

The components of the net deferred tax liability are summarized below.

Class A and Class B common stock.  The shares of Class A common stock and Class B common stock are identical in all respects, except for certain voting rights and certain conversion rights in respect of the shares of the Class B common stock.  Holders of Class A common stock are entitled to one vote per share.  NL, which holds all of the outstanding shares of Class B common stock, is entitled to one vote per share in all matters except for election of directors, for which NL is entitled to ten votes per share.  Holders of all classes of common stock entitled to vote will vote together as a single class on all matters presented to the stockholders for their vote or approval, except as otherwise required by applicable law.  Each share of Class A common stock and Class B common stock have an equal and ratable right to receive dividends to be paid from our assets when and if declared by the board of directors.  In the event of the dissolution, liquidation or winding up of our operations, the holders of Class A common stock and Class B common stock will be entitled to share equally and ratably in the assets available for distribution after payments are made to our creditors and to the holders of any of our preferred stock that may be outstanding at the time.  Shares of the Class A common stock have no conversion rights.  Under certain conditions, shares of Class B common stock will convert, on a share-for-share basis, into shares of Class A common stock.

Share repurchases and cancellations.  Prior to 2015, our board of directors authorized various repurchases of shares of our Class A common stock in open market transactions, including block purchases, or in privately-negotiated transactions at unspecified prices and over an unspecified period of time.  We may repurchase our common stock from time to time as market conditions permit.  The stock repurchase program does not include specific price targets or timetables and may be suspended at any time.  Depending on market conditions, we may terminate the program prior to its completion.  We will generally use cash on hand to acquire the shares.  Repurchased shares will be added to our treasury and cancelled.  We made no treasury purchases during 2015, 2016 or 2017 and at December 31, 2017, approximately 678,000 shares were available for purchase under these authorizations.

Incentive compensation plan.  We have a share based incentive compensation plan pursuant to which an aggregate of up to 200,000 shares of our common stock can be awarded to non-employee members of our board of directors.  All of the Class A common shares we issued in 2015, 2016 and 2017 were issued under this plan.  At December 31, 2017, 166,000 shares were available for award under this plan.

Dividends.  We paid regular quarterly dividends of $.05 per share during 2015, 2016 and 2017.  Declaration and payment of future dividends and the amount thereof, if any, is discretionary and dependent upon our results of operations, financial condition, cash requirements for our businesses, contractual requirements and restrictions and other factors deemed relevant by our board of directors.

Related Party Transactions [Abstract]

Related Party Transactions

Note 9 – Related party transactions:

We may be deemed to be controlled by Ms. Lisa Simmons and Ms. Serena Connelly.  See Note 1.  Corporations that may be deemed to be controlled by or affiliated with these individuals sometimes engage in (a) intercorporate transactions such as guarantees, management and expense sharing arrangements, shared fee arrangements, joint ventures, partnerships, loans, options, advances of funds on open account, and sales, leases and exchanges of assets, including securities issued by both related and unrelated parties and (b) common investment and acquisition strategies, business combinations, reorganizations, recapitalizations, securities repurchases, and purchases and sales (and other acquisitions and dispositions) of subsidiaries, divisions or other business units, which transactions have involved both related and unrelated parties and have included transactions that resulted in the acquisition by one related party of a publicly-held minority equity interest in another related party.  We continuously consider, review and evaluate, and understand that Contran and related entities consider, review and evaluate such transactions.  Depending upon the business, tax and other objectives then relevant, it is possible that we might be a party to one or more such transactions in the future.

From time to time, we may have loans and advances outstanding between us and various related parties pursuant to term and demand notes.  We generally enter into these loans and advances for cash management purposes.  When we loan funds to related parties, we are generally able to earn a higher rate of return on the loan than we would earn if we invested the funds in other instruments.  While certain of these loans may be of a lesser credit quality than cash equivalent instruments otherwise available to us, we believe we have evaluated the credit risks in the terms of the applicable loans.  In this regard, in August 2016, we entered into an unsecured revolving demand promissory note with Valhi whereby we have agreed to loan Valhi up to $40 million.  Our loan to Valhi, as amended, bears interest at prime plus 1.00%, payable quarterly, with all principal due on demand, but in any event no earlier than December 31, 2019.  Loans made to Valhi at any time under the agreement is at our discretion. At December 31, 2016 and 2017, the outstanding principal balance receivable from Valhi under the promissory note was $27.4 million and $38.2 million, respectively.  Interest income (including unused commitment fees) on our loan to Valhi was $0.2 million in 2016 and $1.8 million in 2017.  

Under the terms of an Intercorporate Service Agreement (“ISA”) with Contran, employees of Contran perform certain management, tax planning, financial, legal and administrative services for us on a fee basis.  Such fees are based upon estimates of time devoted to our affairs by individual Contran employees and the compensation of such persons.  Because of the large number of companies affiliated with Contran, we believe we benefit from cost savings and economies of scale gained by not having certain management, financial and administrative staffs duplicated at each entity, thus allowing certain individuals to provide services to multiple companies but only be compensated by one entity.  Fees pursuant to these agreements aggregated $3.0 million in 2015, $3.1 million in 2016 and $2.8 million in 2017.

Contran and certain of its subsidiaries and affiliates, including us, purchase certain of their insurance policies as a group, with the costs of the jointly-owned policies being apportioned among the participating companies.  Tall Pines Insurance Company (“Tall Pines”) and EWI RE, Inc. (“EWI”), each subsidiaries of Valhi, provide for or broker certain insurance policies for Contran and certain of its subsidiaries and affiliates, including us.  Tall Pines purchases reinsurance from third-party insurance carriers with an A.M.  Best Company rating of generally at least A-(Excellent) for substantially all of the risks it underwrites.  Consistent with insurance industry practices, Tall Pines and EWI receive commissions from the insurance and reinsurance underwriters and/or assess fees for the policies that they provide or broker.  The aggregate premiums we paid to Tall Pines and EWI were approximately $1.6 million in 2015, $1.7 million in 2016 and $2.2 million in 2017.  These amounts principally represent payments for insurance premiums, which include premiums or fees paid to Tall Pines or fees paid to EWI.  These amounts also include payments to insurers or reinsurers through EWI for the reimbursement of claims within our applicable deductible or retention ranges that such insurers or reinsurers paid to third parties on our behalf, as well as amounts for claims and risk management services and various other third-party fees and expenses incurred by the program.  We expect that these relationships with Tall Pines and EWI will continue in 2018.  

With respect to certain of such jointly-owned insurance policies, it is possible that unusually large losses incurred by one or more insureds during a given policy period could leave the other participating companies without adequate coverage under that policy for the balance of the policy period. As a result, and in the event that the available coverage under a particular policy would become exhausted by one or more claims, Contran and certain of its subsidiaries and affiliates, including us, have entered into a loss sharing agreement under which any uninsured loss arising because the available coverage had been exhausted by one or more claims will be shared ratably amongst those entities that had submitted claims under the relevant policy. We believe the benefits in the form of reduced premiums and broader coverage associated with the group coverage for such policies justifies the risk associated with the potential for any uninsured loss.

Legal proceedings.  We are involved, from time to time, in various environmental, contractual, product liability, patent (or intellectual property), employment and other claims and disputes incidental to our business.  We currently believe the disposition of all claims and disputes, individually or in the aggregate, should not have a material long-term adverse effect on our consolidated financial condition, results of operations or liquidity.

Environmental matters and litigation.  Our operations are governed by various federal, state and local environmental laws and regulations.  Our policy is to comply with environmental laws and regulations at all of our facilities and to continually strive to improve environmental performance in association with applicable industry initiatives.  We believe that our operations are in substantial compliance with applicable requirements of environmental laws.  From time to time, we may be subject to environmental regulatory enforcement under various statutes, resolution of which typically involves the establishment of compliance programs.

Income taxes.  From time to time, we undergo examinations of our income tax returns, and tax authorities have or may propose tax deficiencies.  We believe that we have adequately provided accruals for additional income taxes and related interest expense which may ultimately result from such examinations and we believe that the ultimate disposition of all such examinations should not have a material adverse effect on our consolidated financial position, results of operations or liquidity.

We are a party to a tax sharing agreement with Contran and NL providing for the allocation of tax liabilities and tax payments as described in Note 1.  Under applicable law, we, as well as every other member of the Contran Tax Group, are each jointly and severally liable for the aggregate federal income tax liability of Contran and the other companies included in the Contran Tax Group for all periods in which we are included in the Contran Tax Group.  NL has agreed, however, to indemnify us for any liability for income taxes of the Contran Tax Group in excess of our tax liability in accordance with the tax sharing agreement.

Concentration of credit risk.  Our products are sold primarily in North America to original equipment manufacturers.  Our ten largest customers accounted for approximately 48% of sales in 2015, 46% in 2016, and 44% in 2017.  One customer of the Security Products segment accounted for 13% of consolidated sales in 2015, 14% in 2016 and 16% in 2017.  Another customer of the Security Products segment accounted for approximately 12% of consolidated sales in 2015 and 11% in 2016.

Rent expense was approximately $0.1 million in 2015 and $0.2 million in each of 2016 and 2017. At December 31, 2017, future minimum rentals under non-cancellable operating leases having an initial or remaining term of more than one year were as follows:

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]

Recent Accounting Pronouncements

Note 12 – Recent Accounting Pronouncements:

Adopted

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-04, Intangibles— Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment, which aims to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test.  Previously, Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill.  Instead, under the new ASU, an entity performs its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and a goodwill impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. In no circumstances will the loss recognized exceed the total amount of goodwill allocated to that reporting unit. We elected to adopt this ASU beginning with our goodwill impairment test performed in the third quarter of 2017. The application of ASU 2017-04 did not have a material effect on our Condensed Consolidated Financial Statements.

Pending Adoption

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606).  This standard replaces existing revenue recognition guidance, which in many cases was tailored for specific industries, with a uniform accounting standard applicable to all industries and transactions.  The new standard, as amended, is currently effective for us beginning with the first quarter of 2018.  Entities may elect to adopt ASU No. 2014-09 retrospectively for all periods for all contracts and transactions which occurred during the period (with a few exceptions for practical expediency) or modified retrospectively with a cumulative effect recognized as of the date of adoption.  We will adopt the standard in the first quarter of 2018 including the expanded disclosure requirements using the modified retrospective approach to adoption. Our sales generally involve single performance obligations to ship goods pursuant to customer purchase orders without further underlying contracts. Prices for our products are based on published price lists, customer agreements and individual customer orders which do not involve variable consideration, financing components, noncash consideration or consideration paid to our customers.  We currently record sales when products are shipped and title and other risks and rewards of ownership have passed to the customer, which is generally upon delivery of our products to transport carriers.  Under ASU 2014-09, we will record sales when our customers obtain control of our products, which we have determined is also upon delivery of our products to transport carriers, consistent with our current practice.  Accordingly, we expect adoption of this standard will have minimal effect on our revenues and disclosure.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is a comprehensive rewriting of the lease accounting guidance which aims to increase comparability and transparency with regard to lease transactions.   The primary change will be the recognition of lease assets for the right-of–use of the underlying asset and lease liabilities for the obligation to make payments by lessees on the balance sheet for leases currently classified as operating leases.   The ASU also requires increased qualitative disclosure about leases in addition to quantitative disclosures currently required.  Companies are required to use a modified retrospective approach to adoption with a practical expedient which will allow companies to continue to account for existing leases under the prior guidance unless a lease is modified, other than the requirement to recognize the right-of-use asset and lease liability for all operating leases. The changes indicated above will be effective for us beginning in the first quarter of 2019, with early adoption permitted. We have not yet evaluated the effect this ASU will have on our Consolidated Financial Statements, but given the amount of our future minimum payments under non-cancellable operating leases at December 31, 2017 totaling $0.4 million, we do not expect the adoption of this standard to have a material effect on our Consolidated Balance Sheet.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2017

Accounting Policies [Abstract]

Organization

Organization.We (NYSE MKT: CIX) are 87% owned by NL Industries, Inc. (NYSE: NL) at December 31, 2017.  We manufacture and sell component products (security products and recreational marine components).  At December 31, 2017, Valhi, Inc. (NYSE: VHI) owns 83% of NL’s outstanding common stock and a wholly-owned subsidiary of Contran Corporation owns 93% of Valhi’s outstanding common stock.  All of Contran’s outstanding voting stock is held by a family trust established for the benefit of Lisa K. Simmons and Serena Simmons Connelly and their children, for which Ms. Simmons and Ms. Connelly are co-trustees, or is held directly by Ms. Simmons and Ms. Connelly or entities related to them.  Consequently, Ms. Simmons and Ms. Connelly may be deemed to control Contran, Valhi, NL and us.  

Unless otherwise indicated, references in this report to “we,” “us,” or “our” refer to CompX International Inc. and its subsidiaries, taken as a whole.

Management Estimates

Management estimates.  In preparing our financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at each balance sheet date and the reported amounts of our revenues and expenses during each reporting period.  Actual results may differ significantly from previously estimated amounts under different assumptions or conditions.

Principles of Consolidation

Principles of consolidation.  Our consolidated financial statements include the accounts of CompX International Inc. and our wholly-owned subsidiaries.  We eliminate all material intercompany accounts and balances.

Fiscal Year

Fiscal year.  Our fiscal year end is always the Sunday closest to December 31, and our operations are reported on a 52 or 53-week fiscal year.  The year ended December 31, 2015 consisted of 53 weeks.  Each of the years ended December 31, 2016 and 2017 consisted of 52 weeks.  For presentation purposes, annual and quarterly information in the consolidated financial statements and accompanying notes are presented as ended on March 31, June 30, September 30 and December 31, as applicable. The actual date of our fiscal years ended December 31, 2015, 2016 and 2017 are January 3, 2016, January 1, 2017, and December 31, 2017, respectively.

Cash and Cash Equivalents

Cash and cash equivalents.  We classify bank time deposits and government and commercial notes and bills with original maturities of three months or less as cash equivalents.

Net Sales

Net sales.  We record sales when products are shipped and title and other risks and rewards of ownership have passed to the customer, which is generally upon delivery of our products to transport carriers.  Amounts charged to customers for shipping and handling are not material.  Sales are stated net of price, early payment and distributor discounts and volume rebates (none of which are material).  We report any tax assessed by a governmental authority that we collect from our customers that is both imposed on and concurrent with our revenue producing activities (such as sales and use taxes) on a net basis (meaning we do not recognize these taxes either in our revenues or in our costs and expenses). See Note 12.

Accounts Receivable

Accounts receivable.  We provide an allowance for doubtful accounts for known and estimated potential losses arising from our sales to customers based on a periodic review of these accounts.

Inventories and Cost of Sales

Inventories and cost of sales.  We state inventories at the lower of cost or net realizable value. We record a provision for obsolete and slow-moving inventories.  We generally base inventory costs for all inventory categories on average cost that approximates the first-in, first-out method.  Inventories include the costs for raw materials, the cost to manufacture the raw materials into finished goods and overhead.  Depending on the inventory’s stage of completion, our manufacturing costs can include the costs of packing and finishing, utilities, maintenance and depreciation, shipping and handling, and salaries and benefits associated with our manufacturing process.  We allocate fixed manufacturing overhead costs based on normal production capacity.  Unallocated overhead costs resulting from periods with abnormally low production levels are charged to expense as incurred.  As inventory is sold to third parties, we recognize the cost of sales in the same period that the sale occurs.  We periodically review our inventory for estimated obsolescence or instances when inventory is no longer marketable for its intended use, and we record any write-down, equal to the difference between the cost of inventory and its estimated net realizable value, based on assumptions about alternative uses, market conditions and other factors.

Selling, General and Administrative Expenses; Advertising Costs

Selling, general and administrative expenses; advertising costs.  Selling, general and administrative expenses include costs related to marketing, sales, distribution, research and development and administrative functions such as accounting, treasury and finance, and includes costs for salaries and benefits, travel and entertainment, promotional materials and professional fees.  We expense advertising and research and development costs as incurred.  Advertising costs were not significant in 2015, 2016 or 2017.

Goodwill

Goodwill.  Goodwill represents the excess of cost over fair value of individual net assets acquired in business combinations.  Goodwill is not subject to periodic amortization.  We evaluate goodwill for impairment annually or when circumstances indicate the carrying value may not be recoverable.  See Note 5.

Property and Equipment; Depreciation Expense

Property and equipment; depreciation expense.  We state property and equipment, including purchased computer software for internal use, at cost.  We compute depreciation of property and equipment for financial reporting purposes principally by the straight-line method over the estimated useful lives of 15 to 40 years for buildings and 3 to 20 years for equipment and software.  We use accelerated depreciation methods for income tax purposes, as permitted.  Depreciation expense was $3.5 million in 2015 and $3.7 million in each of 2016 and 2017.  Upon sale or retirement of an asset, the related cost and accumulated depreciation are removed from the accounts and any gain or loss is recognized in income currently.  Expenditures for maintenance, repairs and minor renewals are expensed; expenditures for major improvements are capitalized.

We perform impairment tests when events or changes in circumstances indicate the carrying value may not be recoverable.  We consider all relevant factors.  We perform the impairment test by comparing the estimated future undiscounted cash flows associated with the asset to the asset’s net carrying value to determine if impairment exists.

Employee Benefit Plans

Employee benefit plans.  We maintain various defined contribution plans in which we make contributions based on matching or other formulas.  Defined contribution plan expense approximated $2.4 million in 2015, $2.6 million in 2016 and $2.4 million in 2017.

Self-Insurance

Self-insurance.  We are partially self-insured for workers’ compensation and certain employee health benefits and self-insured for most environmental issues.  We purchase coverage in order to limit our exposure to any significant levels of workers’ compensation or employee health benefit claims.  We accrue self-insured losses based upon estimates of the aggregate liability for uninsured claims incurred using certain actuarial assumptions followed in the insurance industry and our own historical claims experience.

Income Taxes

Income taxes.  We, and our parent NL, are members of the Contran Tax Group.  We have been and currently are a part of the consolidated tax returns filed by Contran for U.S. federal purposes as well as for certain U.S. state jurisdictions.  As a member of the Contran Tax Group, we are jointly and severally liable for the federal income tax liability of Contran and the other companies included in the Contran Tax Group for all periods in which we are included in the Contran Tax Group.  See Note 10.

As a member of the Contran Tax Group, we are a party to a tax sharing agreement which provides that we compute our provision for U.S. income taxes on a separate-company basis.  Pursuant to the tax sharing agreement, we make payments to or receive payments from NL in amounts we would have paid to or received from the U.S. Internal Revenue Service or the applicable state tax authority had we not been a member of the Contran Tax Group.  The separate company provisions and payments are computed using the tax elections made by Contran.  We made net cash payments for income taxes to NL of $4.7 million in 2015, $4.6 million in 2016 and $6.7 million in 2017.

Deferred income tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the income tax and financial reporting carrying amounts of assets and liabilities.  Deferred income tax assets and liabilities for each tax-paying jurisdiction in which we operate are netted and presented as either a noncurrent deferred income tax asset or liability, as applicable.  We periodically evaluate our deferred tax assets in the various taxing jurisdictions in which we operate and adjust any related valuation allowance based on the estimate of the amount of deferred tax assets which we believe do not meet the more-likely-than-not recognition criteria.  See Notes 7 and 10.

We record a reserve for uncertain tax positions for tax positions where we believe it is more-likely-than-not our position will not prevail with the applicable tax authorities.  We did not have a reserve for uncertain tax positions in each of 2015, 2016 and 2017.
