NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
June 30, 2013
(unaudited)
Note 1—Organization and basis of presentation:
Organization—At June 30, 2013, (i) Valhi, Inc. (NYSE: VHI) held approximately 83% of our outstanding common stock and (ii) Contran Corporation and its subsidiaries held an aggregate of approximately 93% of Valhi’s outstanding common stock. Substantially all of Contran’s outstanding voting stock is held by trusts established for the benefit of certain children and grandchildren of Harold C. Simmons (for which Mr. Simmons is the sole trustee), or is held by Mr. Simmons or other persons or companies related to Mr. Simmons. Consequently, Mr. Simmons may be deemed to control Contran, Valhi and us.
Basis of presentation—Consolidated in this Quarterly Report are the results of our majority-owned subsidiary, CompX International Inc. We also own 30% of Kronos Worldwide, Inc. CompX (NYSE MKT: CIX) and Kronos (NYSE: KRO) each file periodic reports with the Securities and Exchange Commission (SEC).
The unaudited Condensed Consolidated Financial Statements contained in this Quarterly Report have been prepared on the same basis as the audited Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2012 that we filed with the SEC on March 12, 2013 (the 2012 Annual Report). In our opinion, we have made all necessary adjustments (which include only normal recurring adjustments) in order to state fairly, in all material respects, our consolidated financial position, results of operations and cash flows as of the dates and for the periods presented. We have condensed the Consolidated Balance Sheet and Statement of Stockholders’ Equity at December 31, 2012 contained in this Quarterly Report as compared to our audited Consolidated Financial Statements at that date and we have omitted certain information and footnote disclosures (including those related to the Consolidated Balance Sheet at December 31, 2012) normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). Our results of operations for the interim periods ended June 30, 2013 may not be indicative of our operating results for the full year. The Condensed Consolidated Financial Statements contained in this Quarterly Report should be read in conjunction with our 2012 Consolidated Financial Statements contained in our 2012 Annual Report.
Unless otherwise indicated, references in this report to “NL,” “we,” “us” or “our” refer to NL Industries, Inc. and its subsidiaries and affiliate, Kronos, taken as a whole.

Note 2—Discontinued operations:
On December 28, 2012, we completed the sale of CompX’s Furniture Components operations to a competitor of that business. Selected financial data for the operations of the disposed Furniture Components operations is presented below:

Total discontinued operations, net of tax and noncontrolling interest	  	$	774	  	 	$	1,348	  	
 	  	 	 	 	 	 	 	 	
In accordance with generally accepted accounting principles, the assets and liabilities relating to the Furniture Components business were eliminated from the 2012 Condensed Consolidated Balance Sheet at the date of sale. We have reclassified our June 30, 2012 Condensed Consolidated Statements of Operations to reflect the disposed operations as discontinued operations. We have not reclassified our June 30, 2012 Condensed Consolidated Statement of Cash Flows to reflect discontinued operations.
In conjunction with the sale of CompX’s Furniture Components business, the buyer was not interested in retaining certain undeveloped land located in Taiwan owned by CompX’s Taiwanese Furniture Component subsidiary. We had no additional use for the undeveloped land in Taiwan and therefore expected the land to be sold to a third party with CompX receiving the net proceeds. Based on the legal form of how we completed the disposal transaction, our interest in such land was represented by a $3.0 million promissory note receivable at December 31, 2012, issued to CompX by its former Taiwanese subsidiary which retained legal ownership in the land to facilitate the future sale of the land to a third party. The proceeds from the sale of the land were required to be used to settle the note receivable. During the first quarter of 2013, an agreement was entered into with a third party to sell the land for $3.0 million, $1.8 million of which was received during the first quarter of 2013 and the remaining $1.2 million was received in the second quarter 2013. Such note receivable is classified as part of accounts receivable in our Consolidated Balance Sheets at December 31, 2012. See Note 3.

At December 31, 2012 and June 30, 2013, we held approximately 14.4 million shares of Valhi’s common stock with a market price of $12.50 and $13.74 per share, respectively. Contran, Mr. Harold Simmons and persons and other entities related to Mr. Simmons own a majority of Valhi’s outstanding common stock. We account for our investment in Valhi common stock as available-for-sale marketable equity securities and any unrealized gains or losses on the securities are recognized through other comprehensive income, net of deferred income taxes. Our shares of Valhi common stock are carried at fair value based on quoted market prices, representing a Level 1 input within the fair value hierarchy.
The Valhi common stock we own is subject to the restrictions on resale pursuant to certain provisions of the SEC Rule 144. In addition, as a majority-owned subsidiary of Valhi, we cannot vote our shares of Valhi common stock under Delaware Corporation Law, but we do receive dividends from Valhi on these shares, when declared and paid.

Tax authorities are examining certain of our U.S. and non-U.S. tax returns, including those of Kronos, and tax authorities have or may propose tax deficiencies, including penalties and interest. We cannot guarantee these tax matters will be resolved in our favor due to the inherent uncertainties involved in settlement initiatives and court and tax proceedings. We believe we have adequate accruals for additional taxes and related interest expense which could ultimately result from tax examinations. We believe the ultimate disposition of tax examinations should not have a material adverse effect on our consolidated financial position, results of operations or liquidity.
In 2011 and 2012, Kronos received notices of re-assessment from the Canadian federal and provincial tax authorities related to the years 2002 through 2004. Kronos objects to the re-assessments and believes the position is without merit. If the full amount of the proposed adjustment were ultimately to be assessed against Kronos, the cash tax liability would be approximately $15.6 million. Kronos believes that it has adequate accruals for this matter.

Note 14—Commitments and contingencies:
Lead pigment litigation
Our former operations included the manufacture of lead pigments for use in paint and lead-based paint. We, other former manufacturers of lead pigments for use in paint and lead-based paint (together, the “former pigment manufacturers”), and the Lead Industries Association (LIA), which discontinued business operations in 2002, have been named as defendants in various legal proceedings seeking damages for personal injury, property damage and governmental expenditures allegedly caused by the use of lead-based paints. Certain of these actions have been filed by or on behalf of states, counties, cities or their public housing authorities and school districts, and certain others have been asserted as class actions. These lawsuits seek recovery under a variety of theories, including public and private nuisance, negligent product design, negligent failure to warn, strict liability, breach of warranty, conspiracy/concert of action, aiding and abetting, enterprise liability, market share or risk contribution liability, intentional tort, fraud and misrepresentation, violations of state consumer protection statutes, supplier negligence and similar claims.
The plaintiffs in these actions generally seek to impose on the defendants responsibility for lead paint abatement and health concerns associated with the use of lead-based paints, including damages for personal injury, contribution and/or indemnification for medical expenses, medical monitoring expenses and costs for educational programs. To the extent the plaintiffs seek compensatory or punitive damages in these actions, such damages are generally unspecified. In some cases, the damages are unspecified pursuant to the requirements of applicable state law. A number of cases are inactive or have been dismissed or withdrawn. Most of the remaining cases are in various pre-trial stages. Some are on appeal following dismissal or summary judgment rulings in favor of either the defendants or the plaintiffs. In addition, various other cases (in which we are not a defendant) are pending that seek recovery for injury allegedly caused by lead pigment and lead-based paint. Although we are not a defendant in these cases, the outcome of these cases may have an impact on cases that might be filed against us in the future.
We believe that these actions are without merit, and we intend to continue to deny all allegations of wrongdoing and liability and to defend against all actions vigorously. We do not believe it is probable that we have incurred any liability with respect to all of the lead pigment litigation cases to which we are a party, and liability to us that may result, if any, in this regard cannot be reasonably estimated, because:
 
 	•	 	we have never settled any of the market share, risk contribution, intentional tort, fraud, nuisance, supplier negligence, breach of warranty, conspiracy, misrepresentation, aiding and abetting, enterprise liability, or statutory cases,	
 
 	•	 	no final, non-appealable adverse verdicts have ever been entered against us and	
 
 	•	 	we have never ultimately been found liable with respect to any such litigation matters, including over 100 cases over a twenty-year period for which we were previously a party and for which we have been dismissed without any finding of liability.	
 
- 19 -

Table of Contents
Accordingly, we have not accrued any amounts for any of the pending lead pigment and lead-based paint litigation cases. In addition, we have determined that liability to us which may result, if any, cannot be reasonably estimated because there is no prior history of a loss of this nature on which an estimate could be made and there is no substantive information available upon which an estimate could be based.
New cases may continue to be filed against us. We cannot assure you that we will not incur liability in the future in respect of any of the pending or possible litigation in view of the inherent uncertainties involved in court and jury rulings. In the future, if new information regarding such matters becomes available to us (such as a final, non-appealable adverse verdict against us or otherwise ultimately being found liable with respect to such matters), at that time we would consider such information in evaluating any remaining cases then-pending against us as to whether it might then have become probable we have incurred liability with respect to these matters, and whether such liability, if any, could have become reasonably estimable. The resolution of any of these cases could result in the recognition of a loss contingency accrual that could have a material adverse impact on our net income for the interim or annual period during which such liability is recognized and a material adverse impact on our consolidated financial condition and liquidity.
Environmental matters and litigation
Our operations are governed by various environmental laws and regulations. Certain of our businesses are and have been engaged in the handling, manufacture or use of substances or compounds that may be considered toxic or hazardous within the meaning of applicable environmental laws and regulations. As with other companies engaged in similar businesses, certain of our past and current operations and products have the potential to cause environmental or other damage. We have implemented and continue to implement various policies and programs in an effort to minimize these risks. Our policy is to maintain compliance with applicable environmental laws and regulations at all of our plants and to strive to improve environmental performance. From time to time, we may be subject to environmental regulatory enforcement under U.S. and non-U.S. statutes, the resolution of which typically involves the establishment of compliance programs. It is possible that future developments, such as stricter requirements of environmental laws and enforcement policies, could adversely affect our production, handling, use, storage, transportation, sale or disposal of such substances. We believe that all of our facilities are in substantial compliance with applicable environmental laws.
Certain properties and facilities used in our former operations, including divested primary and secondary lead smelters and former mining locations, are the subject of civil litigation, administrative proceedings or investigations arising under federal and state environmental laws and common law. Additionally, in connection with past operating practices, we are currently involved as a defendant, potentially responsible party (PRP) or both, pursuant to the Comprehensive Environmental Response, Compensation and Liability Act, as amended by the Superfund Amendments and Reauthorization Act (CERCLA), and similar state laws in various governmental and private actions associated with waste disposal sites, mining locations, and facilities that we or our predecessors, our subsidiaries or their predecessors currently or previously owned, operated or used, certain of which are on the United States Environmental Protection Agency’s (EPA) Superfund National Priorities List or similar state lists. These proceedings seek cleanup costs, damages for personal injury or property damage and/or damages for injury to natural

Table of Contents
resources. Certain of these proceedings involve claims for substantial amounts. Although we may be jointly and severally liable for these costs, in most cases we are only one of a number of PRPs who may also be jointly and severally liable, and among whom costs may be shared or allocated. In addition, we are also a party to a number of personal injury lawsuits filed in various jurisdictions alleging claims related to environmental conditions alleged to have resulted from our operations.
Obligations associated with environmental remediation and related matters are difficult to assess and estimate for numerous reasons including the:
 
 	•	 	complexity and differing interpretations of governmental regulations,	
 
 	•	 	number of PRPs and their ability or willingness to fund such allocation of costs,	
 
 	•	 	financial capabilities of the PRPs and the allocation of costs among them,	
 
 	•	 	solvency of other PRPs,	
 
 	•	 	multiplicity of possible solutions,	
 
 	•	 	number of years of investigatory, remedial and monitoring activity required,	
 
 	•	 	uncertainty over the extent, if any, to which our former operations might have contributed to the conditions allegedly giving rise to such personal injury, property damage, natural resource and related claims and	
 
 	•	 	number of years between former operations and notice of claims and lack of information and documents about the former operations.	
In addition, the imposition of more stringent standards or requirements under environmental laws or regulations, new developments or changes regarding site cleanup costs or the allocation of costs among PRPs, solvency of other PRPs, the results of future testing and analysis undertaken with respect to certain sites or a determination that we are potentially responsible for the release of hazardous substances at other sites, could cause our expenditures to exceed our current estimates. We cannot assure you that actual costs will not exceed accrued amounts or the upper end of the range for sites for which estimates have been made, and we cannot assure you that costs will not be incurred for sites where no estimates presently can be made. Further, additional environmental and related matters may arise in the future. If we were to incur any future liability, this could have a material adverse effect on our consolidated financial statements, results of operations and liquidity.
We record liabilities related to environmental remediation and related matters when estimated future expenditures are probable and reasonably estimable. We adjust such accruals as further information becomes available to us or as circumstances change. Unless the amounts and timing of such estimated future expenditures are fixed and reasonably determinable, we generally do not discount estimated future expenditures to their present value due to the uncertainty of the timing of the payout. We recognize recoveries of costs from other parties, if any, as assets when their receipt is deemed probable. At June 30, 2013 and December 31, 2012, we have not recognized any receivables for recoveries.
We do not know and cannot estimate the exact time frame over which we will make payments for our accrued environmental and related costs. The timing of payments depends upon a number of factors, including but not

limited to the timing of the actual remediation process; which in turn depends on factors outside of our control. At each balance sheet date, we estimate the amount of our accrued environmental and related costs which we expect to pay within the next twelve months, and we classify this estimate as a current liability. We classify the remaining accrued environmental costs as a noncurrent liability.
Changes in the accrued environmental remediation and related costs during the first six months of 2013 are as follows:

 	  	Amount	 	
 	  	(In thousands)	 	
Balance at the beginning of the period	  	$	48,006	  	
Additions charged to expense, net	  	 	13,041	  	
Payments, net	  	 	(1,256	) 	
 	  	 	 	 	
Balance at the end of the period	  	$	59,791	  	
 	  	 	 	 	
Amounts recognized in the Condensed Consolidated Balance Sheet at the end of the period:	  	 	 	 	
Current liability	  	$	4,754	  	
Noncurrent liability	  	 	55,037	  	
 	  	 	 	 	
Total	  	$	59,791	  	
 	  	 	 	 	
On a quarterly basis, we evaluate the potential range of our liability for environmental remediation and related costs at sites where we have been named as a PRP or defendant, including sites for which our wholly-owned environmental management subsidiary, NL Environmental Management Services, Inc. (EMS), has contractually assumed our obligations. At June 30, 2013, we had accrued approximately $60 million related to approximately 50 sites associated with remediation and related matters that we believe are at the present time and/or in their current phase reasonably estimable. The upper end of the range of reasonably possible costs to us for remediation and related matters for which we believe it is possible to estimate costs is approximately $156 million, including the amount currently accrued.
We believe that it is not reasonably possible to estimate the range of costs for certain sites. At June 30, 2013, there were approximately 5 sites for which we are not currently able to reasonably estimate a range of costs. For these sites, generally the investigation is in the early stages, and we are unable to determine whether or not we actually had any association with the site, the nature of our responsibility, if any, for the contamination at the site and the extent of contamination at and cost to remediate the site. The timing and availability of information on these sites is dependent on events outside of our control, such as when the party alleging liability provides information to us. At certain of these previously inactive sites, we have received general and special notices of liability from the EPA and/or state agencies alleging that we, sometimes with other PRPs, are liable for past and future costs of remediating environmental contamination allegedly caused by former operations. These notifications may assert that we, along with any other alleged PRPs, are liable for past and/or future clean-up costs. As further information becomes available to us for any of these sites, which would allow us to estimate a range of costs, we would at that time adjust our accruals. Any such adjustment could result in the recognition of an accrual that would have a material effect on our consolidated financial statements, results of operations and liquidity.

Insurance coverage claims
We are involved in certain legal proceedings with a number of our former insurance carriers regarding the nature and extent of the carriers’ obligations to us under insurance policies with respect to certain lead pigment and asbestos lawsuits. The issue of whether insurance coverage for defense costs or indemnity or both will be found to exist for our lead pigment and asbestos litigation depends upon a variety of factors and we cannot assure you that such insurance coverage will be available.
We have agreements with three former insurance carriers pursuant to which the carriers reimburse us for a portion of our future lead pigment litigation defense costs, and one such carrier reimburses us for a portion of our future asbestos litigation defense costs. We are not able to determine how much we will ultimately recover from these carriers for defense costs incurred by us because of certain issues that arise regarding which defense costs qualify for reimbursement. While we continue to seek additional insurance recoveries, we do not know if we will be successful in obtaining reimbursement for either defense costs or indemnity. Accordingly, we recognize insurance recoveries in income only when receipt of the recovery is probable and we are able to reasonably estimate the amount of the recovery.
For a complete discussion of certain litigation involving us and certain of our former insurance carriers, refer to our 2012 Annual Report.
Other litigation
We have been named as a defendant in various lawsuits in several jurisdictions, alleging personal injuries as a result of occupational exposure primarily to products manufactured by our former operations containing asbestos, silica and/or mixed dust. In addition, some plaintiffs allege exposure to asbestos from working in various facilities previously owned and/or operated by us. There are 1,125 of these types of cases pending, involving a total of approximately 1,643 plaintiffs. In addition, the claims of approximately 8,298 plaintiffs have been administratively dismissed or placed on the inactive docket in Ohio, Indiana and Texas state courts. We do not expect these claims will be re-opened unless the plaintiffs meet the courts’ medical criteria for asbestos-related claims. We have not accrued any amounts for this litigation because of the uncertainty of liability and inability to reasonably estimate the liability, if any. To date, we have not been adjudicated liable in any of these matters. Based on information available to us, including:
 
 	•	 	facts concerning historical operations,	
 
 	•	 	the rate of new claims,	
 
 	•	 	the number of claims from which we have been dismissed and	
 
 	•	 	our prior experience in the defense of these matters.	
We believe that the range of reasonably possible outcomes of these matters will be consistent with our historical costs (which are not material). Furthermore, we do not expect any reasonably possible outcome would involve amounts material to our consolidated financial position, results of operations or liquidity. We have sought and will continue to vigorously seek, dismissal and/or a finding of no liability from each claim. In addition, from time to time, we have received notices regarding asbestos or silica claims purporting to be brought against former subsidiaries, including notices provided to insurers with which we have entered into settlements extinguishing certain insurance policies. These insurers may seek indemnification from us. For a discussion of other legal proceedings to which we are a party, refer to our 2012 Annual Report.

Table of Contents
In addition to the litigation described above, we and our affiliate are also involved in various other environmental, contractual, product liability, patent (or intellectual property), employment and other claims and disputes incidental to present and former businesses. In certain cases, we have insurance coverage for these items, although we do not expect additional material insurance coverage for environmental matters.
We currently believe the disposition of all of these various other claims and disputes, individually and in the aggregate, should not have a material adverse effect on our consolidated financial position, results of operations or liquidity beyond the accruals already provided.

Net income (loss) overview
Quarter ended June 30, 2013 compared to quarter ended June 30, 2012
Our net loss from continuing operations attributable to NL stockholders was $14.3 million, or $.29 per share, in the second quarter of 2013 compared to net income from continuing operations attributable to NL stockholders of $25.2 million, or $.51 per share, in the second quarter of 2012.
As more fully described below, the decrease in our earnings per share from 2012 to 2013 is primarily due to the net effect of:
 
 	•	 	Equity in losses from Kronos in 2013 compared to equity in earnings from Kronos in 2012,	
 
 	•	 	litigation settlement gain of $15.0 million recognized in the second quarter of 2012 related to the settlement of condemnation proceedings on real property we formerly owned, and	
 
 	•	 	higher environmental remediation and related costs of $10.6 million in the second quarter of 2013.	
Our 2013 net loss from continuing operations attributable to NL stockholders includes income of $.01 per share, net of income taxes, related to insurance recoveries we recognized.
Our 2012 net income from continuing operations attributable to NL stockholders includes:
 
 	•	 	income of $.20 per share, net of income taxes, related to the litigation settlement gain, and	
 
 	•	 	a charge of $.02 per share included in our equity in Kronos related to Kronos’ charge for the early extinguishment of its remaining 6.5% Senior Notes due 2013 consisting of a call premium, interest from the indenture discharge date to the redemption date and the write-off of unamortized deferred financing costs and original issue discount associated with the redeemed Senior Notes.

Net sales—Net sales increased 9% in the second quarter of 2013 and 7% in the first six months of 2013 as compared to the respective periods in 2012. Net sales increased principally due to higher demand for postal products within Security Products, and to a lesser extent, from an increase in Marine Component sales outside of the high performance boat market through gains in market share. Relative changes in selling prices did not have a material impact on net sales comparisons.
Cost of sales and gross margin—Cost of sales as a percentage of sales decreased by approximately 2% in the second quarter of 2013 compared to the second quarter of 2012. As a result, gross margin increased over the same period. The increase in gross margin is primarily due to the improved cost efficiencies from higher sales and the impact of lower self-insured medical insurance costs in the second quarter of 2013 compared to 2012. Cost of sales as a percentage of sales decreased by approximately 1% for the first six months of 2013, primarily due to the improved efficiencies from higher sales. As a result, gross margin also increased over the same period.

Operating costs and expenses—Operating costs and expenses consist primarily of sales and administrative related personnel costs, sales commissions and advertising expenses, as well as gains and losses on plant, property and equipment. As a percentage of net sales, operating costs and expenses for the second quarter and first six months of 2013 are comparable to the same periods in 2012.
Income from operations—As a percentage of net sales, income from operations increased by approximately 2% for the second quarter of 2013, and increased by approximately 1% for the first six months of 2013. These increases were primarily impacted by the factors affecting cost of sales and gross margin noted above.

Table of Contents
Security Products—Security Products net sales increased 8% in the second quarter and 6% in the first six months of 2013 compared to the same periods last year. The increase in sales is primarily due to an increase in sales to postal market customers of $1.8 million and $3.1 million in the second quarter and six month period, respectively, due to an increase in the installation of postal boxes as the U.S. Postal Service transitions to more centralized delivery as part of their cost reduction initiatives.
Gross margin and income from operations as a percentage of sales increased approximately 2% in the second quarter of 2013 compared to the same period in 2012 primarily due to improved cost efficiencies from higher sales and the impact of lower self-insured medical expenses of $.2 million in 2013 which impacted cost of sales and selling and administration expenses. Gross margin and income from operations as a percentage of sales were comparable for the first six months of 2013 and 2012.
Marine Components—Marine Components net sales increased 11% for the second quarter and six month periods in 2013 compared to the same periods in the prior year. The increase in sales is primarily due to gains in market share for products sold to the ski/wakeboard towboat market and other non-high performance marine markets. Gross margin for the second quarter of 2013 increased 4% compared to the second quarter of 2012 and improved 3% for the six month period as compared to the prior year. Income from operations margin increased for the second quarter and six month periods of 2013 by 6% and 7%, respectively, compared to the same periods in 2012 primarily due to increased leverage of fixed costs as a result of the higher sales.
Outlook—Consistent with the current state of the North American economy, overall demand from our customers continues to be subject to instability. While we experienced a total increase in sales in the first half of 2013, this was the net result of sales growth in certain markets and flat or slightly down sales in other markets. As a result, we are uncertain as to the extent that total sales will continue to grow for the remainder of 2013. While changes in market demand are not within our control, we are focused on the areas we can impact. Staffing levels are continuously evaluated in relation to sales order rates which may result in headcount adjustments, to the extent possible, to match staffing levels with demand. We expect our continuous lean manufacturing and cost improvement initiatives to positively impact our productivity and result in a more efficient infrastructure. 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 broaden our sales base and mitigate the impact of changes in demand.
Volatility in the costs of commodity raw materials is ongoing. Our primary commodity raw materials are zinc, brass and stainless steel, which together represent approximately 10% of our total cost of sales. We generally seek to mitigate the impact of fluctuations in commodity raw material costs on our margins through improvements in production efficiencies or other operating cost reductions. In the event we are unable to offset commodity raw material cost increases with other cost reductions, it may be difficult to recover those cost increases through increased product selling prices or surcharges due to the competitive nature of the markets served by our products. Consequently, overall operating margins may be negatively affected by commodity raw material cost pressures.

General corporate and other items
Insurance recoveries—We have agreements with certain insurance carriers pursuant to which the carriers reimburse us for a portion of our past lead pigment and asbestos litigation defense costs. Insurance recoveries include amounts we received from these insurance carriers.
The agreements with certain of our insurance carriers also include reimbursement for a portion of our future litigation defense costs. We are not able to determine how much we will ultimately recover from these carriers for defense costs incurred by us because of certain issues that arise regarding which defense costs qualify for reimbursement. Accordingly, these insurance recoveries are recognized when the receipt is probable and the amount is determinable. See Note 14 to our Condensed Consolidated Financial Statements.
Litigation settlement gain—In May 2012, we reported a $15 million pre-tax gain related to the third and final closing associated with certain real property we formerly owned in New Jersey. See our 2012 Annual Report for a discussion of such gain.
Corporate expense—Corporate expenses were $16.3 million in the second quarter of 2013, $11.2 million higher than in the second quarter of 2012 primarily due to higher environmental remediation and related costs in 2013. Included in corporate expense in the second quarters of 2012 and 2013 are:
 
 	•	 	litigation and related costs of $2.2 million in 2013 compared to $2.1 million in 2012, and	
 
 	•	 	environmental remediation and related costs of $11.8 million in 2013 compared to $1.2 million in 2012.	
Corporate expenses were $21.2 million in the first six months of 2013, which approximated corporate expenses of $21.5 million in the first six months of 2012. Included in corporate expense in the first six months of 2012 and 2013 are:
 
 	•	 	litigation and related costs of $4.3 million in 2013 compared to $4.0 million in 2012, and	
 
 	•	 	environmental remediation and related costs of $13.0 million in 2013 compared to $14.0 million in 2012.	
The level of our litigation and related expenses varies from period to period depending upon, among other things, the number of cases in which we are currently involved, the nature of such cases and the current stage of such cases (e.g. discovery, pre-trial motions, trial or appeal, if applicable). See Note 14 to the Condensed Consolidated Financial Statements. If our current expectations regarding the number of cases in which we expect to be involved during 2013 or the nature of such cases were to change, our corporate expenses could be higher than we currently estimate.
Obligations for environmental remediation costs are difficult to assess and estimate and it is possible that actual costs for environmental remediation will exceed accrued amounts or that costs will be incurred in the future for sites in which we cannot currently estimate our liability. If these events were to occur in 2013, our corporate expenses would be higher than we currently estimate. In addition, we adjust our environmental accruals as further information becomes available to us or as circumstances change. Such further information or changed circumstances could result in an increase in our accrued environmental costs. See Note 14 to the Condensed Consolidated Financial Statements.

Table of Contents
Overall, we currently expect that our net general corporate expenses in 2013 will be comparable to 2012. If our current expectations regarding the number of cases or sites in which we expect to be involved during 2013, or if the nature of such cases or sites were to change, our corporate expenses could be higher than we currently estimate and involve amounts that are material.
Income tax expense (benefit)—We recognized an income tax benefit of $8.0 million in the second quarter of 2013 compared to income tax expense of $7.3 million in the second quarter of 2012, and an income tax benefit of $20.7 million in the first six months of 2013 as compared to income tax expense of $15.3 million in the first six months of 2012 primarily due to lower earnings in 2013. See Note 13 to the Condensed Consolidated Financial Statements for more information about our 2013 income tax items and a tabular reconciliation of our statutory tax expense (benefit) to our actual expense (benefit).
Noncontrolling interest—Noncontrolling interest in net income of CompX attributable to continuing operations is consistent in each of the three and six month periods ended June 30, 2013 and 2012. The noncontrolling interest we recognize in each period is directly related to the level of earnings at CompX for the period.
Discontinued operations—On December 28, 2012, we completed the sale of CompX’s Furniture Components operations. See Note 2 to our Condensed Consolidated Financial Statements.

The key performance indicators for Kronos are TiO2 average selling prices and TiO2 sales and production volumes.
Current industry conditions—In May 2013, Kronos announced price increases for its TiO2 products in all of its markets, implementation of which began in June 2013. As a result, after about a year of decreasing selling prices within the TiO 2 industry, Kronos’ selling prices have generally stabilized, with increases in some accounts. Kronos’ average selling prices at the end of the second quarter of 2013 were 1% lower than at the end of the first quarter of 2013, and were 8% lower than at the end of 2012. Demand for TiO 2  products has increased in the second quarter, primarily in European and export markets, as customers have generally depleted their inventories during the second half of 2012 and the first quarter of 2013 in response to general global economic uncertainty.

While Kronos operated its production facilities at full practical capacity rates in the first quarter of 2012, it operated its facilities at reduced rates during the remainder of 2012 (approximately 86% of practical capacity in the second quarter, approximately 71% in the third quarter and approximately 80% in the fourth quarter) to align production levels and inventories to current and anticipated near-term customer demand levels. Kronos continued to operate its production facilities at reduced capacity rates in the first half of 2013 (approximately 92% of practical capacity in the first quarter and approximately 90% in the second quarter).
Kronos experienced significantly higher costs for its raw materials such as third party feedstock ore and petroleum coke in 2012. Kronos operates two ilmenite mines in Norway, the production from which provides all of the feedstock for its European sulfate process facilities as well as third party ilmenite ore sales. Overall, the cost per metric ton of TiO 2  Kronos produced during 2012 was approximately 50% higher as compared to 2011, primarily due to the higher feedstock ore costs procured from third parties and unabsorbed fixed production costs resulting from reduced production volumes. However, as a substantial portion of the TiO 2  products Kronos sold in the first half of 2012 was produced with lower-cost feedstock ore purchased in 2011, its cost of sales per metric ton in the first quarter of 2012 (and to a lesser-extent the second quarter of 2012) was significantly lower as compared to the cost per metric ton for products Kronos sold in the third and fourth quarters of 2012. Kronos has seen some moderation in the cost of TiO 2 feedstock ore procured from third parties in 2013, but such reductions will not be fully reflected in its cost of sales until the second half of 2013. Consequently, Kronos cost of sales per metric ton of TiO 2  sold in the first half of 2013 (particularly in the first quarter) was significantly higher than what it expects its cost of sales per metric ton of TiO 2  to be in the remainder of 2013, as a substantial portion of the TiO 2  products it sold in the first quarter (and to a lesser-extent the second quarter) of 2013 was produced with the higher-cost feedstock ore procured in 2012.
Net sales—Kronos’ net sales in the second quarter of 2013 decreased 12%, or $64.2 million, compared to the second quarter of 2012 primarily due to the net effects of a 24% decrease in average TiO 2  selling prices (which decreased net sales by approximately $131 million) and a 17% increase in sales volumes (which increased net sales by approximately $93 million).
Kronos’ net sales in the six months ended June 30, 2013 decreased 15%, or $161.9 million, compared to the six months ended June 30, 2012 primarily due to the net effects of a 22% decrease in average TiO 2  selling prices (which decreased net sales by approximately $243 million) and a 9% increase in sales volumes (which increased net sales by approximately $100 million).
TiO2 selling prices will increase or decrease generally as a result of competitive market pressures, changes in the relative level of supply and demand as well as changes in raw material and other manufacturing costs.
Kronos’ sales volumes increased 17% in the second quarter of 2013 as compared to the second quarter of 2012 and increased 9% in the first six months of 2013 as compared to the first six months of 2012 due to higher customer demand, primarily in European and certain export markets. Kronos’ sales volumes in the first six months of 2013 were a new record for a first-half year. Kronos estimates the unfavorable effect of changes in currency exchange rates decreased its net sales by approximately $3 million as compared to the second quarter of 2012 and by approximately $2 million as compared to the first six months of 2012.

Table of Contents
Cost of sales—Kronos’ cost of sales increased $89.5 million or 23% in the second quarter of 2013 compared to 2012 due to the net impact of higher raw material costs of approximately $26 million (primarily feedstock ore), a 17% increase in sales volumes, a 5% increase in TiO 2 production volumes and currency fluctuations (primarily the euro). Kronos’ cost of sales per metric ton of TiO 2  sold in the second quarter of 2013 was somewhat higher than TiO 2  sold in the second quarter of 2012, as a portion of the TiO 2  products it sold in the second quarter of 2012 was produced with lower-cost feedstock ore purchased in 2011, while a portion of the TiO 2  products it sold in the second quarter of 2013 was produced with higher-cost feedstock ore purchased in 2012.
Kronos’ cost of sales increased $249.4 million or 37% in the six months ended June 30, 2013 compared to this same period in 2012 due to the net impact of higher raw material costs of approximately $136 million (primarily feedstock ore), a 9% increase in sales volumes, a 5% decrease in TiO 2  production volumes and currency fluctuations (primarily the euro). Kronos’ cost of sales per metric ton of TiO 2  sold in the first half of 2013 was significantly higher than TiO 2  sold in the first half of 2012, as a substantial portion of the TiO 2  products it sold in the first quarter of 2012 (and a portion of the TiO 2  products it sold in the second quarter of 2012) was produced with lower-cost feedstock ore purchased in 2011, while a substantial portion of the TiO 2  products it sold in the first quarter of 2013 (and a portion of the TiO 2  products it sold in the second quarter of 2013) was produced with higher-cost feedstock ore purchased in 2012.
Overall, and as discussed above, the cost per metric ton of TiO2 Kronos produced during 2012 was approximately 50% higher as compared to 2011, primarily due to the higher feedstock ore costs and unabsorbed fixed production costs resulting from reduced production volumes.
Cost of sales as a percentage of net sales increased to 98% in the second quarter of 2013 compared to 70% in the same period of 2012 primarily due to the effects of lower average selling prices and higher raw materials costs, as discussed and quantified above. Cost of sales as a percentage of net sales increased to 99% in the first six months of 2013 compared to 62% in the same period of 2012 primarily due to the effects of higher raw materials costs as discussed above and a 5% decrease in TiO 2  production volumes.
Unionized employees in Kronos’ Canadian TiO2 production facility are covered by a collective bargaining agreement that expired June 15, 2013. The Canadian facility represents approximately 19% of Kronos’ worldwide TiO 2  production capacity. The union employees represented by the Confederation des Syndicat National (CSN) rejected Kronos’ revised global offer, and Kronos declared a lockout of unionized employees upon the expiration of the existing contract. As of the date of this report, no agreement has been reached with the CSN and the unionized employees remain locked out. Kronos is currently operating its Canadian plant at approximately 15% of the plant’s capacity with non-union management employees, and has implemented a strategy to reduce the financial impact of operating the plant during the lockout. Kronos currently expects minimal interruptions in meeting customer demand, as orders are being filled with inventory on hand or through production from its other facilities. There is no assurance that Kronos will able to reach an agreement with the CSN on the terms of a new collective bargaining agreement, or reach an agreement on terms that will not have a material adverse effect on its results of operations.

Gross margin and income (loss) from operations—Kronos’ income (loss) from operations decreased by $158.3 million from income of $110.6 million in the second quarter of 2012 to a loss of $47.7 million in the second quarter of 2013. Income (loss) from operations as a percentage of net sales decreased to (10)% in the second quarter of 2013 from 20% in the same period of 2012. This decrease was driven by the decline in gross margin, which decreased to 2% for the second quarter of 2013 compared to 30% for the second quarter of 2012. Kronos’ gross margin in the second quarter has decreased primarily due to the net effects of lower selling prices, higher manufacturing costs (primarily raw materials), higher sales volumes and higher production volumes.
Kronos’ income (loss) from operations decreased by $414.6 million from income of $320.0 million in the first six months of 2012 to a loss of $94.6 million in the first six months of 2013. Income (loss) from operations as a percentage of net sales decreased to (10)% in the first six months of 2013 from 29% in the same period of 2012. This decrease was driven by the decline in gross margin, which decreased to 1% for the first six months of 2013 compared to 38% for the same period in 2012. Kronos’ gross margin in the first six months of 2013 has decreased primarily due to the net effects of lower selling prices, higher manufacturing costs (primarily raw materials), higher sales volumes and lower production volumes.
Additionally, changes in currency exchange rates have negatively affected its gross margin and income from operations. Kronos estimates that changes in currency exchange rates decreased income from operations by approximately $2 million in the second quarter of 2013 as compared to the same period in 2012 and decreased income from operations by approximately $8 million in the first six months of 2013 as compared to the same period in 2012.
Other non-operating income (expense)—In June 2012, Kronos entered into a new $400 million term loan. Kronos used a portion of the net proceeds of the term loan to redeem the remaining outstanding 6.5% Senior Secured Notes due April 2013 (€279.2 million principal amount outstanding). As a result, Kronos recognized an aggregate $7.2 million pre-tax charge in the second quarter of 2012 related to the early extinguishment of debt, consisting of the call premium paid, interest from the June 14, 2012 indenture discharge date to the July 20, 2012 redemption date and the write-off of unamortized deferred financing costs and original issue discount associated with the redeemed Senior Secured Notes. In the first quarter of 2013, Kronos recognized an aggregate $6.6 million pre-tax charge, consisting of the write-off of unamortized original issue discount costs and deferred financing costs, related to the voluntary prepayment of $290 million of its term loan.
Kronos’ interest expense decreased $1.0 million from $6.7 million in the second quarter of 2012 to $5.7 million in the second quarter of 2013 and decreased $.9 million from $13.0 million in the six months ended June 30, 2012 to $12.1 million in the six months ended June 30, 2013 primarily due to lower average debt levels in 2013.
Kronos’ interest and dividend income decreased $1.7 million to $.3 million in the second quarter of 2013 and decreased $3.7 million to $.6 million in the six months ended June 30, 2013 primarily due to lower balances available for investment, principally related to its loan to Valhi which was completely repaid in December 2012. Interest income on Kronos’ loan to Valhi was $1.7 million in the second quarter of 2012 and $3.4 million in the six months ended June 30, 2012.

Income tax expense (benefit)—Kronos recognized an income tax benefit of $19.2 million in the second quarter of 2013 compared to an income tax provision of $34.2 million in the same period last year and an income tax benefit of $37.7 million in the first six months of 2013 compared to an income tax provision of $102.7 million in the same period last year. This difference is primarily due to Kronos’ decreased earnings.
Kronos has substantial net operating loss carryforwards in Germany (the equivalent of $744 million and $100 million for German corporate and trade tax purposes, respectively, at December 31, 2012). At June 30, 2013, Kronos has concluded that no deferred income tax asset valuation allowance is required to be recognized with respect to such carryforwards, principally because (i) such carryforwards have an indefinite carryforward period, (ii) Kronos has utilized a portion of such carryforwards during the most recent three-year period and (iii) Kronos currently expects to utilize the remainder of such carryforwards over the long term. However, prior to the complete utilization of such carryforwards, particularly if Kronos were to generate losses in its German operations for an extended period of time, it is possible that Kronos might conclude the benefit of such carryforwards would no longer meet the more-likely-than-not recognition criteria, at which point it would be required to recognize a valuation allowance against some or all of the then-remaining tax benefit associated with the carryforwards.
Effects of Currency Exchange Rates
Kronos has substantial operations and assets located outside the United States (primarily in Germany, Belgium, Norway and Canada). The majority of its sales from non-U.S. operations are denominated in currencies other than the U.S. dollar, principally the euro, other major European currencies and the Canadian dollar. A portion of Kronos’ sales generated from its non-U.S. operations is denominated in the U.S. dollar. Certain raw materials used worldwide, primarily titanium-containing feedstocks, are purchased in U.S. dollars, while labor and other production costs are purchased primarily in local currencies. Consequently, the translated U.S. dollar value of Kronos’ non-U.S. sales and operating results are subject to currency exchange rate fluctuations which may favorably or unfavorably impact reported earnings and may affect the comparability of period-to-period operating results. In addition to the impact of the translation of sales and expenses over time, Kronos’ non-U.S. operations also generate currency transaction gains and losses which primarily relate to the difference between the currency exchange rates in effect when non-local currency sales or operating costs are initially accrued and when such amounts are settled with the non-local currency.
Overall, Kronos estimates that fluctuations in currency exchange rates had the following effects on its sales and income from operations for the periods indicated.

Outlook
During the first half of 2013 Kronos operated its production facilities at 91% of practical capacity, which was a higher utilization rate as compared to its utilization rates during the last three quarters of 2012. If economic conditions improve in the various regions of the world in the remainder of 2013, Kronos expects demand for its TiO 2  products would continue to increase and it would expect its sales volumes to be higher in 2013 as compared to 2012. During 2013, Kronos will continue to monitor current and anticipated near-term customer demand levels and align its production and inventories accordingly.
Kronos saw some moderation in the cost of TiO2 feedstock ore procured in 2013, but such reductions will not be fully reflected in its cost of sales until the second half of 2013. Consequently, Kronos’ cost of sales per metric ton of TiO 2  sold in the first half of 2013 was significantly higher than what it expects its cost of sales per metric ton of TiO 2  to be in the remainder of 2013, as a substantial portion of the TiO 2  products Kronos sold in the first quarter of 2013 (and a portion of the TiO 2  products it sold in the second quarter of 2013) was produced with the higher-cost feedstock ore procured in 2012. Although the cost of feedstock ore has and continues to moderate, such reductions have been inadequate to compensate for the decline in selling prices for Kronos’ products over the past year. Kronos started 2013 with selling prices 16% lower than as compared to the beginning of 2012, and prices declined by an additional 7% in the first quarter of 2013 and 1% in the second quarter. In May 2013, Kronos announced price increases for its TiO 2  products in all of its markets, implementation of which began in June 2013. As a result, Kronos’ selling prices have generally stabilized, with increases in some accounts. Kronos expects to implement additional increases in selling prices during the second half of 2013. Industry data indicates that overall TiO 2  inventory held by producers has been significantly decreased, Kronos believes most customers hold very low inventories of TiO 2  with many operating on a just-in-time basis. As a result, shortages of certain TiO 2  grades have begun to occur, and lead times for delivery are increasing. With the record sales volumes levels experienced in the first half of the year, Kronos continues to see evidence of improvement in demand for its TiO 2  products, which it believes will support implementation of additional selling price increases in the near term. The extent to which Kronos will be able to achieve these and other possible additional price increases during 2013 will depend on market conditions.

Table of Contents
Overall, Kronos expects that income (loss) from operations in 2013 will be significantly lower as compared to 2012, but it also expects income (loss) from operations in the second half of 2013 will improve from the first half of 2013. Kronos’ income from operations in the first half of 2012 was positively affected by the sale of TiO 2  produced with lower-cost feedstock ore purchased in 2011, while its loss from operations in the first half of 2013 was negatively impacted by the sale of TiO 2  produced with higher-cost feedstock ore purchased in 2012. The negative effect of such higher-cost feedstock ore on Kronos’ full year 2013 operating results is expected to more than offset any favorable effect of higher sales and production volumes that would result assuming demand levels continue to improve, as well as the favorable impact of increases in its selling prices that Kronos may be able to achieve during the remainder of 2013.
Due to the constraints, high capital costs and extended lead time associated with adding significant new TiO2 production capacity, especially for premium grades of TiO 2  products produced from the chloride process, Kronos believes increased and sustained profit margins will be necessary to financially justify major expansions of TiO 2  production capacity required to meet expected future growth in demand. As a result of customer decisions over the last year and the resulting adverse effect on global TiO 2  pricing, industry projects to increase TiO 2  production capacity have been cancelled or deferred indefinitely. Given the lead time required for such production capacity expansions, Kronos expects a prolonged shortage of TiO 2  products will occur as economic conditions improve and global demand levels for TiO 2  continue to increase.
Kronos’ expectations as to the future of the TiO2 industry are based upon a number of factors beyond its control, including worldwide growth of gross domestic product, competition in the marketplace, continued operation of competitors, unexpected or earlier-than-expected capacity additions or reductions and technological advances. If actual developments differ materially from its expectations, Kronos’ results of operations could be unfavorably affected.
LIQUIDITY AND CAPITAL RESOURCES
Consolidated cash flows
Operating activities
Trends in cash flows from operating activities, excluding the impact of deferred taxes and relative changes in assets and liabilities, are generally similar to trends in our income from operations. Net cash provided by operating activities was $2.6 million in the first six months of 2013 compared to $4.5 million in the first six months of 2012.
The $1.9 million decrease in cash provided by operating activities includes the net effects of:
 
 	•	 	the $3.1 million of income from operations in 2012 attributable to CompX’s disposed operations,	
 
 	•	 	higher amount of net cash used for relative changes in receivables, inventories, payables and accrued liabilities in 2013 of $1.8 million,	
 
 	•	 	lower amounts paid for environmental remediation and related costs in 2013 of $.7 million, and	
 
 	•	 	lower cash paid for income taxes in 2013 of $1.7 million.

We expect our operating cash flow comparisons for the remainder of 2013 will continue to be negatively impacted by the sale of CompX’s disposed operations, since the operating cash flows of the disposed operations are included in our total cash flows from operating activities in 2012, through the December 2012 date of sale. See Note 2 to our Condensed Consolidated Financial Statements.
We do not have complete access to CompX’s cash flows in part because we do not own 100% of CompX. A detail of our consolidated cash flows from operating activities is presented in the table below. Intercompany dividends have been eliminated. The reference to NL Parent in the table below is a reference to NL Industries, Inc., as the parent company of CompX and our wholly-owned subsidiaries.

 	•	 	we paid $12.2 million, or $.25 per share, in dividends. Distributions to noncontrolling interests consist of CompX dividends paid to shareholders other than us.

In July 2013, CompX prepaid the remaining outstanding principal amount of the long-term debt, plus accrued interest, without penalty. See Note 9 to the Condensed Consolidated Financial Statements.
Provisions contained in Kronos’ credit agreements could result in the acceleration of any indebtedness prior to its stated maturity for reasons other than defaults from failure to comply with applicable covenants. For example, certain credit agreements allow the lender to accelerate the maturity of the indebtedness upon a change of control (as defined in the agreement) of the borrower. In addition, certain credit agreements could result in the acceleration of all or a portion of the indebtedness following a sale of assets outside of the ordinary course of business.
Kronos is in compliance with all of its respective debt covenants at June 30, 2013. Kronos’ ability to borrow funds under its credit facility in the future will, in some instances, depend in part on compliance with specified financial covenants and restrictions contained in the applicable credit agreements. We believe that Kronos will be able to comply with its financial covenants through the maturity of its facility; however if future operating results differ materially from our predictions Kronos may be unable to maintain compliance. In such an event, Kronos believes it has alternate sources of liquidity, including cash on hand and borrowings under its North American revolver or additional borrowings from Contran (neither of which contain any financial maintenance covenants) in order to adequately address any compliance issues which might arise.
In July 2013, Kronos voluntarily prepaid the remaining $100 million principal amount outstanding under its term loan, using $50 million of cash on hand as well as borrowings of $50 million under its revolving North American credit facility. Kronos expects to recognize a non-cash pre-tax interest charge of approximately $2.3 million in the third quarter of 2013 consisting of the write-off of the remaining unamortized original issue discount and deferred financing costs associated with such payment.
Future cash requirements
Liquidity
Our primary source of liquidity on an ongoing basis is our cash flow from operating activities and credit facilities with affiliates and banks as further discussed below. We generally use these amounts to (i) fund capital expenditures (substantially all of which relate to CompX), (ii) pay ongoing environmental remediation and legal expenses and (iii) provide for the payment of debt service and dividends (if declared).
At June 30, 2013, we had aggregate cash, cash equivalents and restricted cash of $77.8 million, substantially all of which was held in the U.S. A detail by entity is presented in the table below.

 	  	Amount	 	
 	  	(In millions)	 	
CompX	  	$	52.7	  	
NL Parent and wholly-owned subsidiaries	  	 	25.1	  	
 	  	 	 	 	
Total	  	$	77.8

In addition, at June 30, 2013 we owned 14.4 million shares of Valhi common stock with an aggregate market value of $197.5 million. See Note 5 to the Condensed Consolidated Financial Statements. We also owned 35.2 million shares of Kronos common stock at June 30, 2013 with an aggregate market value of $572.0 million. See Note 6 to the Condensed Consolidated Financial Statements.
We routinely compare our liquidity requirements and alternative uses of capital against the estimated future cash flows we expect to receive from our subsidiaries and affiliates. As a result of this process, we have in the past and may in the future seek to raise additional capital, incur debt, repurchase indebtedness in the market or otherwise, modify our dividend policies, consider the sale of our interests in our subsidiaries, affiliates, business, marketable securities or other assets, or take a combination of these and other steps, to increase liquidity, reduce indebtedness and fund future activities. Such activities have in the past and may in the future involve related companies.
We periodically evaluate acquisitions of interests in or combinations with companies (including related companies) perceived by management to be undervalued in the marketplace. These companies may or may not be engaged in businesses related to our current businesses. We intend to consider such acquisition activities in the future and, in connection with this activity, may consider issuing additional equity securities and increasing indebtedness. From time to time, we also evaluate the restructuring of ownership interests among our respective subsidiaries and related companies.
Based upon our expectations of our operating performance, and the anticipated demands on our cash resources we expect to have sufficient liquidity to meet our short-term obligations (defined as the twelve-month period ending June 30, 2014). If actual developments differ materially from our expectations, our liquidity could be adversely affected. In this regard, Valhi has agreed to loan us up to $40 million on a revolving basis. At June 30, 2013, we had no outstanding borrowings under this facility, and the full $40 million was available for future borrowing. The amount of any such outstanding loan Valhi would make to us is at Valhi’s discretion. We currently do not expect to be required to borrow any amounts from Valhi during 2013 under this facility.
Capital Expenditures
Firm purchase commitments for capital projects in process at June 30, 2013 approximated $1.1 million. CompX’s 2013 capital investments are limited to those expenditures required to meet expected customer demand and those required to properly maintain or improve facilities and technology infrastructure.
Dividends
Because our operations are conducted primarily through subsidiaries and affiliates, our long-term ability to meet parent company-level corporate obligations is largely dependent on the receipt of dividends or other distributions from our subsidiaries and affiliates. A detail of annual dividends we would expect to receive from our subsidiaries and affiliates in 2013, based on the number of shares of common stock of these affiliates we own as of June 30, 2013 and their current regular quarterly dividend rate, is presented in the table below. In May 2013, CompX’s board of directors reduced its regular quarterly dividend from $.125 per share to $0.05 per share, effective with its second quarter 2013 dividend. The amount shown in the table

below for CompX reflects the $.125 per share and $.05 per share dividends we actually received from CompX in the first and second quarters, respectively, and $.05 per share we would expect to receive in each of the third and fourth quarters of 2013.

Investments in our subsidiaries and affiliates and other acquisitions
We have in the past and may in the future, purchase the securities of our subsidiaries and affiliates or third-parties in market or privately-negotiated transactions. We base our purchase decisions on a variety of factors, including an analysis of the optimal use of our capital, taking into account the market value of the securities and the relative value of expected returns on alternative investments. In connection with these activities, we may consider issuing additional equity securities or increasing our indebtedness. We may also evaluate the restructuring of ownership interests of our businesses among our subsidiaries and related companies.
Off-balance sheet financing arrangements
Other than operating lease commitments discussed in our 2012 Annual Report, we are not party to any material off-balance sheet financing arrangements.
Commitments and contingencies
There have been no material changes in our contractual obligations since we filed our 2012 Annual Report (other than the prepayment of CompX’s outstanding long-term debt in July 2013, as discussed above), and we refer you to that report for a complete description of these commitments.
We are subject to certain commitments and contingencies, as more fully described to our 2012 Annual Report, or in Note 14 to our Condensed Consolidated Financial Statements or in Part II, Item 1 of this report, including certain legal proceedings. In addition to such legal proceedings, various legislation and administrative regulations have, from time to time, been proposed that seek to (i) impose various obligations on present and former manufacturers of lead pigment and lead-based paint (including us) with respect to asserted health concerns associated with the use of such products and (ii) effectively overturn court decisions in which we and other pigment manufacturers have been successful. Examples of such proposed legislation include bills which would permit civil liability for damages on the basis of market share, rather than requiring plaintiffs to prove that the defendant’s product caused the alleged damage and bills which would revive actions barred by the statute of limitations. While no legislation or regulations have been enacted to date that are expected to have a material adverse effect on our consolidated financial position, results of operations or liquidity, enactment of such legislation could have such an effect.

Recent accounting pronouncements
Not applicable
Critical accounting policies and estimates
For a discussion of our critical accounting policies, refer to Part I, Item 7—“Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2012 Annual Report. There have been no changes in our critical accounting policies during the first six months of 2013.
 
ITEM 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK	
We are exposed to market risk, including currency exchange rates, interest rates and security prices. There have been no material changes in these market risks since we filed our 2012 Annual Report, and we refer you to Part I, Item 7A.—“Quantitative and Qualitative Disclosure About Market Risk” in our 2012 Annual Report. See also Note 15 to our Condensed Consolidated Financial Statements.
 
ITEM 4.	CONTROLS AND PROCEDURES	
Evaluation of disclosure controls and procedures—We maintain a system of disclosure controls and procedures. The term “disclosure controls and procedures,” as defined by 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 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. Each of Steven L. Watson, our Vice Chairman and Chief Executive Officer, and Gregory M. Swalwell, our Executive Vice President and Chief Financial Officer, have evaluated the design and effectiveness of our disclosure controls and procedures as of June 30, 2013. Based upon their evaluation, these executive officers have concluded that our disclosure controls and procedures are effective as of June 30, 2013.
Internal control over financial reporting—We also maintain internal control over financial reporting. The term “internal control over financial reporting,” as defined by 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 GAAP, and includes those policies and procedures that:
 
 	•	 	pertain to the maintenance of records that in reasonable detail accurately and fairly reflect 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 made only in accordance with authorizations of our management and directors and	
 
- 45 -

Table of Contents
 	•	 	provide reasonable assurance regarding prevention or timely detection of an unauthorized acquisition, use or disposition of assets that could have a material effect on our Condensed Consolidated Financial Statements.	
As permitted by the SEC, our assessment of internal control over financial reporting excludes (i) internal control over financial reporting of equity method investees and (ii) internal control over the preparation of our financial statement schedules required by Article 12 of Regulation S-X. However, our assessment of internal control over financial reporting with respect to equity method investees did include our controls over the recording of amounts related to our investment that are recorded in our Condensed Consolidated Financial Statements, including controls over the selection of accounting methods for our investments, the recognition of equity method earnings and losses and the determination, valuation and recording of our investment account balances.
Changes in internal control over financial reporting—There has been no change to our internal control over financial reporting during the quarter ended June 30, 2013 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
