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:

- 2 -

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 recreational transportation, postal, office and institutional furniture, cabinetry, tool storage and healthcare applications. We also manufacture stainless steel exhaust systems, gauges, throttle controls, wake enhancement systems 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 electrical 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 cash containment 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 which is 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:

- 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, wake enhancement systems, trim tabs and related 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 which is 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:

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:

These raw materials are purchased from several suppliers, are readily available from numerous sources and accounted for approximately 12% of our total cost of sales for 2018.  Total material costs, including purchased components, represented approximately 45% of our cost of sales in 2018.

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 2017 and 2018, markets for the primary commodity-related raw materials used in the manufacture of our locking mechanisms, primarily zinc and brass, generally strengthened, but were moderating at the end of 2018. Over that same period, the market for stainless steel, the primary raw material used for the manufacture of marine exhaust headers and pipes and wake enhancement systems, remained relatively stable. While we expect the markets for our primary commodity-related raw materials to remain stable during 2019, we recognize that economic conditions could introduce renewed volatility 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.  When possible, we 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

- 4 -

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 1 year to 16 years at December 31, 2018.  

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

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 2018 (United States Postal Service representing 13%). Our largest ten customers accounted for approximately 44% of our sales in 2018.

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 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, 2018, we employed 547 people, all in the United States.  We believe our labor relations are good at all of our facilities.

Website and 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.  For presentation purposes, annual and quarterly information in this Form 10-K 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, 2016, 2017 and 2018 are January 1, 2017, December 31, 2017, and December 30, 2018, respectively. 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.

We are an electronic filer.  The SEC maintains an internet website at www.sec.gov that contains reports, proxy and information statements and other information regarding issuers, such as us, that file electronically with the SEC.

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.

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 and aluminum are the major raw materials used in the manufacture of marine components.  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.

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.  

None.

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, wake enhancement systems and trim tabs for the recreational marine and other industries through our Marine Components segment.

Operating Income Overview

We reported operating income of $17.8 million in 2018 compared to operating income of $15.2 million in 2017 and $15.6 million in 2016. The increase in operating income in 2018 over 2017 is primarily due to higher sales at both Security Products and Marine Components. Operating income in 2017 was comparable to operating income in 2016.

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 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:

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

- 12 -

markets served, are consistent with factors utilized with our internal projections and operating plan.  However, future events and circumstances could result in materially different findings which could result in the recognition of a material goodwill impairment.

Results of Operations - 2018 Compared to 2017 and 2017 Compared to 2016

Net Sales. Net sales increased approximately $6.2 million in 2018 compared to 2017 primarily due to higher Marine Components sales volumes to manufacturers of ski/wakeboard boats and larger center-console boats, and to a lesser extent higher Security Products sales to certain markets, particularly transportation and office furniture. Relative changes in selling prices did not have a material impact on net sales comparisons.

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 ski/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 2017 to 2018 primarily due to increased sales volumes for both the Security Products and Marine Components segments. Gross profit dollars and gross profit as a percentage of sales increased from 2017 to 2018 primarily due to greater fixed cost leverage facilitated by higher production volumes for each of our business segments.

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

- 13 -

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.

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 sales of property, plant and equipment.  Operating costs and expenses as a percentage of sales were comparable in 2016, 2017 and 2018.

Operating Income. As a percentage of net sales, operating income increased from 2017 to 2018 while operating income decreased slightly from 2016 to 2017.  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 45% of our cost of sales in 2018, with commodity-related raw materials accounting for approximately 12% of our cost of sales. During 2017 and 2018, markets for the primary commodity-related raw materials used in the manufacture of our locking mechanisms, primarily zinc and brass, generally strengthened, but were moderating at the end of 2018. Over that same period, the market for stainless steel, the primary raw material used for the manufacture of marine exhaust headers and pipes and wake enhancement systems, remained relatively stable. While we expect the markets for our primary commodity-related raw materials to remain stable during 2019, we recognize that economic conditions could introduce renewed volatility 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 2018 increased compared to 2017 primarily due to higher interest rates on our loan to an affiliate (originated late in 2016) as well as our cash investments. Interest income in 2017 increased compared to 2016 due to higher average balances on our loan to an affiliate 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 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 2016, 23% in 2017 and 25% in 2018. Our effective income tax rate was lower in 2017 and 2018 as compared to 2016 as a result of tax reform legislation. On December 22, 2017, H.R.1, formally known as the “Tax Cuts and Jobs Act” (“2017 Tax Act”) was enacted into law. This tax legislation, among other changes, (i) reduced the U.S Federal corporate income tax rate from 35% to 21% effective January 1, 2018; (ii) eliminated the domestic production activities deduction beginning in 2018; and (iii) allowed 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 required that companies account for changes related to the 2017 Tax Act in the period of enactment unless the impact of such changes could not be reasonably estimated.  Where the use of estimated provisional amounts was necessary, SAB 118 provided for a measurement period of no longer than one year during which companies could adjust those amounts as additional information became available. Therefore, as required under GAAP, we revalued our net deferred tax liability associated with our net taxable temporary differences 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 were not materially different from

- 14 -

our temporary differences as of the enactment date; accordingly revaluation of our net taxable temporary differences was 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 for the period ended December 31, 2017, reducing our net deferred income tax liability as of that date.  During 2018 we finalized our analysis of the 2017 Tax Act and recorded an immaterial adjustment within the defined measurement period. See Notes 7 and 10 to our Consolidated Financial Statements.

While our effective income tax rate for 2018 was favorably impacted by the reduction in the U.S. federal statutory income tax rate from 35% to 21%, our effective income tax rate was higher in 2018 as compared to 2017 due to the $1.9 million non-cash deferred income tax benefit recognized in 2017 resulting from the revaluation of our net deferred income tax liability discussed above.  We currently expect our effective income tax rate for 2019 to be comparable to 2018.

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 our Consolidated Financial Statements.

Security Products.  Security Products net sales increased 2% to $98.4 million in 2018 compared to $96.6 million in 2017, primarily due to higher sales to the transportation and office furniture markets. As a percentage of sales, gross profit for 2018 increased slightly over 2017 due to lower production costs, including headcount reductions made during the second quarter of 2017, and improved coverage of fixed costs over increased production volumes.  Operating costs and expenses for 2018 were slightly lower than 2017.  As a result, Security Products operating income as a percentage of net sales for 2018 exceeded 2017.

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 employee

- 15 -

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.

Marine Components.  Marine Components net sales increased 29% in 2018 as compared to 2017 as a result of continued strong demand for our products, particularly those sold to the ski/wakeboard boat market as well as to manufacturers of large center-console boats and industrial customers. Gross profit margin and operating income as a percentage of net sales increased in 2018 compared to 2017 principally due to improved fixed cost leverage facilitated by higher production volumes.

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.

Outlook

Our 2018 sales growth was largely attributable to high demand for our marine products, where we continue to benefit from innovation and diversification in our product offerings to the recreational boat markets. We also increased sales of security products, particularly to the transportation and office furniture markets. In 2019, we will seek to maintain the positive momentum in each of our business segments 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 2018, 2017 and 2016. See Note 1 to our 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 $17.2 million in 2018 compared to $12.6 million in 2017.  The $4.6 million increase in cash provided by operating activities is primarily the net result of:  

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 was primarily the net result of:

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, 2017 to December 31, 2018 primarily as a result of the timing of sales and collections in the last month of 2018 as compared to 2017.  For comparative purposes, we have provided 2016 numbers below.

As shown below, our average number of days in inventory at December 31, 2018 is comparable to December 31, 2017. The variability in days in inventory among our segments primarily relates to the complexity of

- 17 -

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 2016 numbers below.

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 $3.2 million in 2016, $2.8 million in 2017 and $3.1 million in 2018.  See Note 2 to our Consolidated Financial Statements.  Capital expenditures in 2016 include approximately $1.0 million for an expansion to our Grayslake facility which was completed in April 2016.    

Capital expenditures for 2019 are estimated at approximately $4.8 million primarily to maintain and improve the cost-effectiveness of our facilities and equipment.  Capital spending for 2019 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, as amended,  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, 2020.  Loans made to Valhi at any time under the agreement are at our discretion.  During the third and fourth quarters of 2016, Valhi 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 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). During 2018, Valhi repaid a net $4.2 million under the promissory note for an outstanding balance of $34.0 million at December 31, 2018 ($46.8 million of gross borrowings and $51.0 million of gross repayments). See Note 9 to our Consolidated Financial Statements.

Financing activities.  Cash dividends paid totaled $2.5 million ($.20 per share, or $.05 per share per quarter) in each of 2016, 2017 and 2018. On February 27, 2019 our board of directors declared a first quarter 2019 dividend of $.07 per share, to be paid on March 19, 2019 to CompX stockholders of record as of March 11, 2019.  The declaration and payment of future dividends and the amount thereof, if any, is discretionary and is 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.  The amount and timing of past dividends is not necessarily indicative of the amount or timing of any future dividends which we might pay.

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 $45.4 million aggregate cash and cash equivalents at December 31, 2018 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

- 18 -

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 our 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 our Consolidated Financial Statements.  The following table summarizes such contractual commitments as of December 31, 2018 by the type and date of payment.

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, 2018, which is assumed to be paid during 2019.  Fixed asset acquisitions include firm purchase commitments for capital projects.  

Recent accounting pronouncements

See Note 12 to our Consolidated Financial Statements.

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

Interest rates.  We are exposed to market risk from changes in interest rates, primarily related to our note receivable from affiliate.  The outstanding principal amount of indebtedness of $34.0 million at December 31, 2018 bears interest at prime plus 1.0% (6.5% at December 31, 2018). We received interest income of $2.1 million from the note during 2018.  

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.

Report of Independent Registered Public Accounting Firm

To the Board 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 (the “Company”) as of December 30, 2018 and December 31, 2017, and the related consolidated statements of income, stockholders’ equity and cash flows for each of the three years in the period ending December 30, 2018, including the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 30, 2018 and December 31, 2017, and the results of its operations and its cash flows for each of the three years in the period ending December 30, 2018 in 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.
