Simmons (for which Mr. Simmons is the sole trustee), or is held by Mr. Simmons or other persons or entities related to Mr. Simmons. Consequently, Mr. Simmons may be deemed to control Contran, Valhi and us.

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

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

Principles of consolidation—The consolidated financial statements include our accounts and those of our majority-owned subsidiaries. We have eliminated all material intercompany accounts and balances.

Translation of currencies—We translate the assets and liabilities of our subsidiaries whose functional currency is other than the U.S. dollar at year-end exchange rates, while we translate our revenues and expenses at average exchange rates prevailing during the year. We accumulate the resulting translation adjustments in stockholders’ equity as part of accumulated other comprehensive income (loss), net of related deferred income taxes. We recognize currency transaction gains and losses in income currently.

Derivatives and hedging activities—We recognize derivatives as either assets or liabilities measured at fair value. We recognize the effect of changes in the fair value of derivatives either in net income or other comprehensive income (loss), depending on the intended use of the derivative.

Cash and cash equivalents—We classify bank time deposits and U.S. Treasury securities purchased under short-term agreements to resell with original maturities of three months or less as cash equivalents.

Restricted cash and cash equivalents – We classify cash and cash equivalents that have been segregated or are otherwise limited in use as restricted. To the extent the restricted amount relates to a recognized liability, we classify such restricted amount as either a current or noncurrent asset to correspond with the classification of the liability. To the extent the restricted amount does not relate to a recognized liability, we classify restricted cash as a current asset. See Note 7.

Marketable securities and securities transactions—We carry marketable debt and equity securities at fair value. Accounting Standard Codification (ASC) Topic 820, Fair Value Measurements and Disclosures, establishes a consistent framework for measuring fair value and (with certain exceptions) this framework is generally applied to all financial statement items required to be measured at fair value. The standard requires fair value measurements to be classified and disclosed in one of the following three categories:

•

Level 1 – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

•

Level 2 – Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the assets or liability; and

•

Level 3 – Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable.

We classify all of our marketable securities as available-for-sale and unrealized gains or losses on these securities are recognized through other comprehensive income, net of deferred income taxes, except for any decline in value we conclude is other than temporary, which is accounted for as a realized loss as a component of net income. We base realized gains and losses upon the specific identification of the securities sold.

We evaluate our investments whenever events or conditions occur to indicate that the fair value of such investments has declined below their carrying amounts. If the carrying amount for an investment declines below its historical cost basis, we evaluate all available positive and negative evidence including, but not limited to, the extent and duration of the impairment, business prospects for the investee and our intent and ability to hold the investment for a reasonable period of time sufficient for the recovery of fair value. If we determine the decline in fair value is other than temporary, the carrying amount of the investment is written down to fair value.

See Notes 6, 11 and 16.

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

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

Investment in TiO₂ manufacturing joint venture—We account for our investment in a 50%-owned manufacturing joint venture by the equity method. See Note 5.

Property and equipment and depreciation—We state property and equipment at cost, including capitalized interest on borrowings during the actual construction period of major capital projects. Capitalized interest costs were $.9 million in 2010, $1.0 million in 2011 and $1.1 million in 2012. We compute depreciation of property and equipment for financial reporting purposes (including mining equipment) principally by the straight-line method over the estimated useful lives of the assets as follows:


Asset		Useful lives
Buildings and improvements		10 to 40 years
Machinery and equipment		3 to 20 years
Mine development costs		units-of-production

We use accelerated depreciation methods for income tax purposes, as permitted. Upon the sale or retirement of an asset, we remove the related cost and accumulated depreciation from the accounts and recognize any gain or loss in income currently.

We expense costs incurred for maintenance, repairs and minor renewals (including planned major maintenance) while we capitalize expenditures for major improvements.

We have a governmental concession with an unlimited term to operate our ilmenite mines in Norway. Mining properties consist of buildings and equipment used in our Norwegian ilmenite mining operations and costs associated with the development of a new mine area which commenced production prior to 2010. While we own the land and ilmenite reserves associated with the mining operations, such land and reserves were acquired for nominal value and we have no material asset recognized for the land and reserves related to our mining operations.

We perform impairment tests when events or changes in circumstances indicate the carrying value may not be recoverable. We consider all relevant factors. We perform the impairment test by comparing the estimated future undiscounted cash flows (exclusive of interest expense) associated with the asset to the asset’s net carrying value to determine if a write-down to fair value or discounted cash flow value is required.

Long-term debt—We state long-term debt net of any unamortized original issue premium or discount. We classify amortization of deferred financing costs and any premium or discount associated with the issuance of indebtedness as interest expense and compute such amortization by either the interest method or the straight-line method over the term of the applicable issue.

Employee benefit plans—Accounting and funding policies for our retirement plans are described in Note 11.

Income taxes—We, Valhi and our qualifying subsidiaries are members of Contran’s consolidated U.S. federal income tax group (the Contran Tax Group) and we and certain of our qualifying subsidiaries also file consolidated income tax returns with Contran in various U.S. state jurisdictions. As a member of the Contran Tax Group, we are jointly and severally liable for the federal income tax liability of Contran and the other companies included in the Contran Tax Group for all periods in which we are included in the Contran Tax Group. See Note 15. As a member of the Contran Tax Group, we are a party to a tax sharing agreement which provides that we compute our provision for U.S. income taxes on a separate-company basis using the tax elections made by Contran. Pursuant to the tax sharing agreement, we make payments to or receive payments from Valhi in amounts we would have paid to or received from the U.S. Internal Revenue Service or the applicable state tax authority had we not been a member of the Contran Tax Group. We made net payments of income taxes to Valhi of $13.6 million in 2010, $43.5 million in 2011 and $32.1 million in 2012.

We recognize deferred income tax assets and liabilities for the expected future tax consequences of temporary differences between the income tax and financial reporting carrying amounts of assets and liabilities, including investments in our subsidiaries and affiliates who are not members of the Contran Tax Group and undistributed earnings of non-U.S. subsidiaries which are not deemed to be permanently reinvested. The earnings of non-U.S. subsidiaries subject to permanent reinvestment plans aggregated $978 million at December 31, 2011 and $1.0 billion at December 31, 2012. It is not practical for us to determine the amount of the unrecognized deferred income tax liability related to such earnings due to the complexities associated with the U.S. taxation on earnings of non-U.S. subsidiaries repatriated to the U.S. We periodically evaluate our deferred tax assets in the various taxing jurisdictions in which we operate and adjust any related valuation allowance based on the estimate of the amount of such deferred tax assets that we believe does not meet the more-likely-than-not recognition criteria.

We record a reserve for uncertain tax positions for tax positions where we believe that it is more-likely-than-not our position will not prevail with the applicable tax authorities. The amount of the benefit associated with our uncertain tax positions that we recognize is limited to the largest amount for which we believe the likelihood of realization is greater than 50%. We accrue penalties and interest on the difference between tax positions taken on our tax returns and the amount of benefit recognized for financial reporting purposes. We classify our reserves for uncertain tax positions in a separate current or noncurrent liability, depending on the nature of the tax position. See Note 10.

Net sales—We record sales when products are shipped and title and other risks and rewards of ownership have passed to the customer, or when services are performed. Shipping terms of products shipped are generally FOB shipping point, although in some instances shipping terms are FOB destination point (for which we do not recognize sales until the product is received by the customer) or other standard shipping terms. We state sales net of price, early payment and distributor discounts and volume rebates. We report any tax assessed by a governmental authority that we collect from our customers that is both imposed on and concurrent with our revenue-producing activities (such as sales, use, value added and excise taxes) on a net basis (meaning we do not recognize these taxes either in our revenues or in our costs and expenses).

Selling, general and administrative expense; shipping and handling costs—Selling, general and administrative expense includes costs related to marketing, sales, distribution, shipping and handling, research and development, legal, and administrative functions such as accounting, treasury and finance, and includes costs for salaries and benefits not associated with our manufacturing process, travel and entertainment, promotional materials and professional fees. We include shipping and handling costs in selling, general and administrative expense and these costs were $83 million in 2010, $93 million in 2011 and $89 million in 2012. We expense advertising costs as incurred and these costs were approximately $1 million in each of 2010 and 2011 and approximately $.5 million in 2012. We expense research, development and certain sales technical support costs as incurred and these costs approximated $13 million in 2010, $20 million in 2011 and $19 million in 2012.

Note 2—Geographic information:

Our operations are associated with the production and sale of titanium dioxide pigments (TiO₂). TiO₂ is used to impart whiteness, brightness, opacity and durability to a wide variety of products, including paints, plastics, paper, fibers and ceramics. Additionally, TiO₂ is a critical component of everyday applications, such as coatings, plastics and paper, as well as many specialty products such as inks, foods and cosmetics. At December 31, 2011 and 2012 the net assets of non-U.S. subsidiaries included in consolidated net assets approximated $478.2 million and $580.5 million, respectively.

For geographic information, we attribute net sales to the place of manufacture (point of origin) and to the location of the customer (point of destination); we attribute property and equipment to their physical location.

Investment in TiO2 manufacturing joint venture

Note 5—Investment in TiO₂ manufacturing joint venture:

We own a 50% interest in Louisiana Pigment Company, L.P. (LPC). LPC is a manufacturing joint venture whose other 50%-owner is Tioxide Americas Inc. (Tioxide). Tioxide is a wholly-owned subsidiary of Huntsman Corporation. LPC owns and operates a chloride-process TiO₂ plant in Lake Charles, Louisiana.

We and Tioxide are both required to purchase one-half of the TiO₂ produced by LPC, unless we and Tioxide agree otherwise (such as in 2012, when we purchased approximately 52% of the production from the plant). LPC operates on a break-even basis and, accordingly, we report no equity in earnings of LPC. Each owner’s acquisition transfer price for its share of the TiO₂ produced is equal to its share of the joint venture’s production costs and interest expense, if any. Our share of net cost is reported as cost of sales as the related TiO₂ acquired from LPC is sold. We report distributions we receive from LPC, which generally relate to excess cash generated by LPC from its non-cash production costs, and contributions we make to LPC, which generally relate to cash required by LPC when it builds working capital, as part of our cash flows from operating activities in our Consolidated Statements of Cash Flows. The components of our net distributions from LPC are shown in the table below.

Note 6 – Marketable securities:

At December 31, 2012, our marketable securities consist of investments in the publicly-traded shares of related parties: Valhi, NL and CompX International Inc. At December 31, 2012, Valhi and NL own 50% and 30%, respectively, of our outstanding common stock and NL owns the majority of CompX’s outstanding common stock. All of our marketable securities are accounted for as available-for-sale securities, which are carried at fair value using quoted market prices in active markets for each marketable security and represent a Level 1 input within the fair value hierarchy. See Note 16. Because we have classified all of our marketable securities as available-for-sale, any unrealized gains or losses on the securities are recognized through other comprehensive income, net of deferred income taxes.

At December 31, 2011 and 2012, we held approximately 1.7 million shares of Valhi’s common stock, which we purchased during 2010 and 2011. We also held a nominal number of shares of CompX and NL common stocks. At December 31, 2011 and 2012, the quoted per share market price of Valhi’s common stock was $20.16 and $12.50, respectively. In May 2012, Valhi implemented a 3-for-1 split of its common stock. We have adjusted all share and per-share disclosures related to our investment in Valhi stock for all periods prior to May 2012 to give effect to the stock split. The stock split had no financial statement impact to us, and our ownership interest in Valhi did not change as a result of the split.

At December 31, 2011, we held approximately 4.2 million shares, or 2.4%, of Titanium Metals Corporation’s (TIMET) outstanding common stock, which we purchased during 2010 and 2011. At December 31, 2011, the quoted market price was $14.98 per share. Prior to December 2012, TIMET was also an affiliate of ours, as Contran, Mr. Harold Simmons and persons and other entities related to Mr. Simmons (including us) owned a majority of TIMET’s outstanding common stock. In December 2012, we sold all of our shares of TIMET common stock for $70.0 million ($16.50 per share) pursuant to a cash tender offer by a third party, and all of our affiliates also sold their shares of TIMET common stock for the same price. Securities transactions in 2012 consist of a $3.9 million pre-tax loss we recognized on the sale of these TIMET shares.

The Valhi, CompX and NL common stocks we own are subject to the restrictions on resale pursuant to certain provisions of the Securities and Exchange Commission (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.

At December 31, 2011, we held investments in various mutual funds which have a primary investment objective of holding corporate and government debt securities from U.S. and other markets. These funds were liquidated for cash proceeds in the first quarter of 2012.

Term Loan – In June 2012, we entered into a $400 million term loan. We used a portion of the net proceeds of the term loan to redeem the remaining outstanding 6.5% Senior Secured Notes (€279.2 million principal amount outstanding), as discussed below. The term loan was issued at 98.5% of the principal amount, or an aggregate of $394 million. The term loan provides for an additional $100 million of term loan borrowings in the future under certain conditions. The remaining net proceeds of the term loan, plus any additional term loan which might be borrowed in the future, are available for our general corporate purposes. The term loan permits the continued payment of regular quarterly dividends as well as the payment of special dividends, if any. The term loan:

•

bears interest, at our option, at LIBOR (with LIBOR no less than 1.0%) plus 4.75%, or the base rate, as defined in the agreement, plus 3.75%. The average interest rate on these borrowings at December 31, 2012, and for the period from issuance to December 31, 2012, was 5.75% and 5.82%, respectively;

•

requires quarterly principal repayments of $5.0 million commencing in September 2012, other mandatory principal repayments of formula-determined amounts under specified conditions with all remaining principal balance due in June 2018. Voluntary principal prepayments are permitted at any time (without penalty);

•

is collateralized by, among other things, a first priority lien on (i) 100% of the common stock of certain of our U.S. wholly-owned subsidiaries, (ii) 65% of the common stock or other ownership interest of our Canadian subsidiary (Kronos Canada, Inc.) and certain first-tier European subsidiaries (Kronos Titan GmbH and Kronos Denmark ApS) and (iii) a $362.1 million unsecured promissory note issued by our wholly-owned subsidiary, Kronos International, Inc. (KII) to us;

•

is also collateralized by a second priority lien on all of the U.S. assets which collateralize our new North American revolving facility, as discussed below;

contains a number of covenants and restrictions which, among other things, restrict our ability to incur additional debt, incur liens, pay dividends or merge or consolidate with, or sell or transfer substantially all of our assets to, another entity, contains other provisions and restrictive covenants customary in lending transactions of this type and requires the maintenance of a specified financial covenant (leverage to EBITDA, as defined) to be less than or equal to 3.5 to 1.0; and

•

contains customary default provisions, including a default under any of our other indebtedness in excess of $50 million.

The carrying amount of the term loan includes unamortized original issue discount of $5.5 million at December 31, 2012.

In February 2013, we voluntarily prepaid an aggregate $290 million principal amount of the term loan. Funds for such prepayment were provided by $100 million of our cash on hand as well as borrowings of $190 million under a new loan from Contran. Such new loan from Contran contains terms and conditions substantially identical to the terms and conditions of the term loan, except that the loan from Contran is unsecured and contains no financial maintenance covenant. As a result of this prepayment, the remaining $100 million principal amount of the term loan is not repayable until final maturity of the term loan in June 2018. It is possible we might borrow additional amounts from Contran in the future to voluntarily prepay the remaining $100 million principal amount outstanding under the term loan. The independent members of our board of directors approved the terms and conditions of the new loan from Contran.

Senior Secured Notes—In March 2011, we redeemed €80 million of our €400 million 6.5% Senior Secured Notes at 102.17% of the principal amount for an aggregate of $115.7 million, including a $2.5 million call premium. During the third and fourth quarters of 2011, we repurchased in open market transactions an aggregate of €40.8 million principal amount of the Senior Notes for an aggregate of €40.6 million (an aggregate of $57.6 million when repurchased). Following such partial redemption and repurchases, €279.2 million principal amount of Senior Notes remained outstanding. We recognized a $3.3 million pre-tax interest charge related to the redemption of €80 million of the 6.5% Senior Secured Notes consisting of the call premium, the write-off of unamortized deferred financing costs and original issue discount associated with the redeemed Senior Notes. We recognized a $.2 million net gain on the €40.8 million principal amount of Senior Notes repurchased in open market transactions. We borrowed under our European revolving credit facility, as discussed below, in order to fund the redemption in March 2011, while we used cash on hand to fund the open market repurchases.

Immediately upon the June 2012 issuance of the term loan as discussed above, we sent a request to the trustee under the indenture for the Senior Notes, asking that all remaining Senior Notes be called for redemption on July 20, 2012. We also directed that a portion of the proceeds from the new term loan be irrevocably sent to the trustee, in an amount sufficient to pay the principal, call premium at 1.01083% of the principal amount and all accrued and unpaid interest due through the July 20, 2012 redemption date. Upon the trustee’s confirmation of receipt of such funds on June 14, 2012, the trustee discharged our obligations under the indenture and released the liens on all collateral thereunder. Because we were released as being the primary obligor under the indenture as of June 14, 2012, the Senior Notes were derecognized as of that date along with the funds irrevocably sent to the trustee to effect the July 20, 2012 redemption. We recognized an aggregate $7.2 million pre-tax charge related to the early extinguishment of debt in the second quarter of 2012, 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 Notes.

Revolving credit facilities

Revolving North American credit facility – Also in June 2012, we entered into a $125 million revolving bank credit facility which matures June 2017. Borrowings under the revolving credit facility are available for our general corporate purposes. Available borrowings on this facility are based on formula-determined amounts of eligible trade receivables and inventories, as defined in the agreement, of certain of our North American subsidiaries less any outstanding letters of credit up to $15 million issued under the facility (with revolving borrowings by our Canadian subsidiary limited to $25 million). Any amounts outstanding under the revolving credit facility bear interest, at our option, at LIBOR plus a margin ranging from 1.5% to 2.0% or at the applicable base rate, as defined in the agreement, plus a margin ranging from .5% to 1.0%. The credit facility is collateralized by, among other things, a first priority lien on the borrowers’ trade receivables and inventories. The facility contains a number of covenants and restrictions which, among other things, restricts the borrowers’ ability to incur additional debt, incur liens, pay dividends or merge or consolidate with, or sell or transfer all or substantially all of their assets to, another entity, contains other provisions and restrictive covenants customary in lending transactions of this type and under certain conditions requires the maintenance of a specified financial covenant (fixed charge coverage ratio, as defined) to be at least 1.0 to 1.0. During December 2012, we borrowed and repaid $71 million under this facility at an average interest rate of 3.75%. At December 31, 2012, we had no outstanding borrowings under this revolving credit facility and approximately $125 million was available for borrowing.

Revolving European credit facility—Our operating subsidiaries in Germany, Belgium, Norway and Denmark have a €120 million secured revolving bank credit facility that, as amended in September 2012, matures in September 2017. We may denominate borrowings in Euros, Norwegian kroner or U.S. dollars. Outstanding borrowings bear interest at LIBOR plus 1.90%. The facility is collateralized by the accounts receivable and inventories of the borrowers, plus a limited pledge of all of the other assets of the Belgian borrower. The facility contains certain restrictive covenants that, among other things, restrict the ability of the borrowers to incur debt, incur liens, pay dividends or merge or consolidate with, or sell or transfer all or substantially all of the assets to, another entity, and requires the maintenance of certain financial ratios. In addition, the credit facility contains customary cross-default provisions with respect to other debt and obligations of the borrowers, KII and its other subsidiaries.

During 2012, we borrowed €80 million ($107.4 million when borrowed) under our European credit facility, and subsequently repaid €70 million ($88.6 million when repaid). The average interest rate on these borrowings as of and for the year ended December 31, 2012 was 1.88% and 2.01%, respectively. As of December 31, 2012, the equivalent of $144.9 million was available for borrowing under this facility.

Canada – In December 2011, our Canadian subsidiary entered into a Cdn. $10.0 million loan agreement with the Bank of Montreal for the limited purpose of issuing letters of credit. The facility renews annually. Letters of credit are collateralized by restricted deposits at the Bank of Montreal ($7.5 million at December 31, 2012). See Note 7. The facility contains certain restrictive covenants which, among other things, restrict the subsidiary from incurring additional indebtedness in excess of Cdn. $35 million. At December 31, 2012, an aggregate of Cdn. $7.5 million letters of credit were outstanding under this facility.

In December 2011, our Canadian subsidiary entered into an agreement with an economic development agency of the Province of Quebec, Canada pursuant to which we may borrow up to Cdn. $7.1 million from such agency. Borrowings may only be used to fund capital improvements at our Canadian plant and are limited to a specified percentage of such capital improvements. Borrowings are non-interest bearing, with monthly payments commencing in 2017. The agreement contains certain restrictive covenants, which, among other things, restricts the subsidiary’s ability to sell assets or enter into mergers, and requires our subsidiary to maintain certain financial ratios and maintain specified levels of employment. At December 31, 2012, we had no borrowings under this agreement.

Note payable to affiliate—From time to time, companies related to Contran will have loans and advances outstanding between them and various related parties pursuant to term and demand notes. In this regard, in April 2010 we entered into an unsecured revolving credit note with Contran pursuant to which we could borrow up to $40 million from Contran. Our loans from Contran bore interest, payable quarterly, at the prime rate minus 0.5%, with all outstanding principal due on demand and in any event no later than December 31, 2011. The principal amount borrowed at any time was solely at the discretion of Contran. This facility terminated upon its maturity in December 2011. See Note 14.

Our provision for income taxes in 2011 includes $17.2 million for U.S. incremental income taxes on current earnings repatriated from our German subsidiary, which earnings were used to fund a portion of the repurchases of our Senior Secured Notes discussed in Note 9. In addition, we accrue U.S. incremental income taxes on the earnings of our Canadian subsidiary, which earnings we previously determined are not permanently reinvested.

In the third quarter of 2012, France enacted certain changes in their income tax laws, including a 3% nondeductible surtax on all dividend distributions on which tax is assessed at the time of the distribution against the company making such distribution. Consequently, our French subsidiary will be required to pay an additional 3% tax on all future dividend distributions. Our undistributed earnings in France are deemed to be permanently reinvested and such tax will be recognized as part of our income tax expense if and when a dividend is declared and at that time the related tax will be remitted to the French government in accordance with the applicable tax law. During 2012, our French subsidiary distributed an $8.9 million dividend. At December 31, 2012, our French subsidiary has undistributed earnings of approximately $10.8 million that, if distributed, would be subject to the 3% surtax.

As a consequence of a European Court ruling that resulted in a favorable resolution of certain income tax issues in Germany, during the first quarter of 2010 the German tax authorities agreed to an increase in our German net operating loss carryforwards. Accordingly, we recognized a non-cash income tax benefit of $35.2 million in the first quarter of 2010.

Tax authorities are examining certain of our U.S. and non-U.S. tax returns and have or may propose tax deficiencies, including penalties and interest. Because of the inherent uncertainties involved in settlement initiatives and court and tax proceedings, we cannot guarantee that these tax matters will be resolved in our favor, and therefore our potential exposure, if any, is also uncertain. In 2011 and 2012 we received notices of re-assessment from the Canadian federal and provincial tax authorities related to the years 2002 through 2004. We object to the re-assessments and believe the position is without merit. Accordingly, we are appealing the re-assessments and in connection with such appeal we were required to post letters of credit aggregating Cdn. $7.5 million (see Note 9). If the full amount of the proposed adjustment were ultimately to be assessed against us the cash tax liability would be approximately $16.0 million. 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.

We accrue interest and penalties on our uncertain tax positions as a component of our provision for income taxes. The amount of interest and penalties we accrued during 2010, 2011 and 2012 was not material, and at December 31, 2010, 2011 and 2012, we had $2.7 million, $3.1 million and $3.4 million, respectively, accrued for interest and penalties for our uncertain tax positions.

The following table shows the changes in the amount of our uncertain tax positions (exclusive of the effect of interest and penalties) during 2010, 2011 and 2012:

Change in currency exchange rates		.4			(.4	)		.3

Unrecognized tax benefits at end of year	$	7.9		$	8.8		$	13.0

If our uncertain tax positions were recognized, a benefit of $10.6 million, $11.9 million and $16.4 million would affect our effective income tax rates for 2010, 2011 and 2012 respectively. We currently estimate that our unrecognized tax benefits will not change materially during the next twelve months.

We file income tax returns in various U.S. federal, state and local jurisdictions. We also file income tax returns in various non-U.S. jurisdictions, principally in Germany, Canada, Belgium and Norway. Our U.S. income tax returns prior to 2009 are generally considered closed to examination by applicable tax authorities. Our non-U.S. income tax returns are generally considered closed to examination for years prior to 2008 for Germany, 2009 for Belgium, 2007 for Canada and 2003 for Norway.

At December 31, 2012, we had the equivalent of $744 million and $100 million of net operating loss carryforwards for German corporate and trade tax purposes, respectively. At December 31, 2012, we have 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) we have utilized a portion of such carryforwards during the most recent three-year period and (iii) we currently expect to utilize the remainder of such carryforwards over the long term. However, prior to the complete utilization of these carryforwards, particularly if the economic recovery were to be short-lived or we generate operating losses in our German operations for an extended period of time, it is possible we might conclude the benefit of the carryforwards would no longer meet the more-likely-than-not recognition criteria, at which point we would be required to recognize a valuation allowance against some or all of the then-remaining tax benefit associated with the carryforwards.

Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Employee benefit plans

Note 11 — Employee benefit plans:

Defined contribution plans—We maintain various defined contribution pension plans with our contributions based on matching or other formulas. Defined contribution plan expense approximated $1.2 million in 2010, $1.5 million in 2011 and $1.6 million in 2012.

Accounting for defined benefit and postretirement benefits other than pensions (OPEB) plans—We recognize an asset or liability for the over or under funded status of each of our individual defined benefit pension plans on our Consolidated Balance Sheets. Changes in the funded status of these plans are recognized either in net income (loss), to the extent they are reflected in periodic benefit cost, or through other comprehensive income (loss).

Defined benefit plans—We sponsor various defined benefit pension plans. Non-U.S. employees are covered by plans in their respective countries and a majority of U.S. employees are eligible to participate in a contributory savings plan. The benefits under our plans are based upon years of service and employee compensation. Our funding policy is to contribute annually the minimum amount required under ERISA (or equivalent non-U.S.) regulations plus additional amounts as we deem appropriate.

We expect to contribute the equivalent of approximately $26.9 million to all of our defined benefit pension plans during 2013. Benefit payments to plan participants out of plan assets are expected to be the equivalent of:

These amounts will be recognized as components of our periodic defined benefit cost in future years and are recognized, net of deferred income taxes, in our accumulated other comprehensive income (loss) at December 2011 and 2012. We expect approximately $12.5 million, $1.1 million and $.4 million of the unrecognized actuarial losses, prior service costs and net transition obligations, respectively, will be recognized as components of our consolidated net periodic defined benefit pension cost in 2013.

The table below details the changes in our consolidated other comprehensive income (loss) during 2010, 2011 and 2012.

At December 31, 2011 and 2012, substantially all of the assets attributable to our U.S. plan were invested in the Combined Master Retirement Trust (CMRT), a collective investment trust sponsored by Contran to permit the collective investment by certain master trusts that fund certain employee benefits plans sponsored by Contran and certain of its affiliates. The CMRT’s long-term investment objective is to provide a rate of return exceeding a composite of broad market equity and fixed income indices (including the S&P 500 and certain Russell indices) while utilizing both third-party investment managers as well as investments directed by Mr. Simmons. Mr. Simmons is the sole trustee of the CMRT. The trustee of the CMRT, along with the CMRT’s investment committee, of which Mr. Simmons is a member, actively manage the investments of the CMRT.

The CMRT trustee and investment committee do not maintain a specific target asset allocation in order to achieve their objectives, but instead they periodically change the asset mix of the CMRT based upon, among other things, advice they receive from third-party advisors and their expectations regarding potential returns for various investment alternatives and what asset mix will generate the greatest overall return. Prior to December 2012, the CMRT had an investment in TIMET common stock; however, in December 2012 the CMRT sold its shares of common stock in conjunction with the tender offer discussed in Note 6. During the history of the CMRT from its inception in 1988 through December 31, 2012, the average annual rate of return has been 14%. For the years ended December 31, 2010, 2011 and 2012, the assumed long-term rate of return for plan assets invested in the CMRT was 10%. In determining the appropriateness of the long-term rate of return assumption, we primarily rely on the historical rates of return achieved by the CMRT, although we consider other factors as well including, among other things, the investment objectives of the CMRT’s managers and their expectation that such historical returns will in the future continue to be achieved over the long-term.

The CMRT unit value is determined semi-monthly, and the plans have the ability to redeem all or any portion of their investment in the CMRT at any time based on the most recent semi-monthly valuation. However, the plans do not have the right to individual assets held by the CMRT and the CMRT has the sole discretion in determining how to meet any redemption request. For purposes of our plan asset disclosure, we consider the investment in the CMRT as a Level 2 input because (i) the CMRT value is established semi-monthly and the plans have the right to redeem their investment in the CMRT, in part or in whole, at anytime based on the most recent value and (ii) observable inputs from Level 1 or Level 2 were used to value approximately 83% of the assets of the CMRT at each of December 31, 2011 and 2012, as noted below. The aggregate fair value of all of the CMRT assets, including funds of Contran and its other affiliates that also invest in the CMRT, and supplemental asset mix details of the CMRT are as follows:


	December 31,
	2011			2012

		100	%		100	%

The increase in the relative portion of the CMRT invested in cash and other assets at December 31, 2012 is the result of the CMRT’s December 2012 disposition of its shares of TIMET common stock, which generated aggregate proceeds to the CMRT of $254.7 million (or approximately 35% of the CMRT’s total asset value at December 31, 2012), and which funds were invested in a cash equivalent at the end of 2012. Subsequently in January 2013, the CMRT redeployed such proceeds into other investments.

In determining the expected long-term rate of return on non-U.S. plan asset assumptions, we consider the long-term asset mix (e.g. equity vs. fixed income) for the assets for each of our plans and the expected long-term rates of return for such asset components. In addition, we receive third-party advice about appropriate long-term rates of return. Such assumed asset mixes are summarized below:

•

In Germany, the composition of our plan assets is established to satisfy the requirements of the German insurance commissioner. Our German pension plan assets represent an investment in a large collective investment fund established and maintained by Bayer AG in which several pension plans, including our German pension plan and Bayer’s pension plans, have invested. Our plan assets represent a very nominal portion of the total collective investment fund maintained by Bayer. These plan assets are a Level 3 input because there is not an active market that approximates the value of our investment in the Bayer investment fund. We determine the fair value of the Bayer plan assets based on periodic reports we receive from the managers of the Bayer plan. These periodic reports are subject to audit by the German pension regulator.

•

In Canada, we currently have a plan asset target allocation of 46% to equity securities, 45% to fixed income securities, 9% to other investments and the remainder to cash. We expect the long-term rate of return for such investments to average approximately 125 basis points above the applicable equity or fixed income index. The Canadian assets are Level 1 input because they are traded in active markets.

•

In Norway, we currently have a plan asset target allocation of 12% to equity securities, 78% to fixed income securities, 9% to real estate and the remainder primarily to other investments and liquid investments such as money markets. The expected long-term rate of return for such investments is approximately 8%, 4%, 6% and 7%, respectively. The majority of Norwegian plan assets are Level 1 inputs because they are traded in active markets; however approximately 10% of our Norwegian plan assets are invested in real estate and other investments not actively traded and are therefore a Level 3 input.

•

We also have plan assets in Belgium and the United Kingdom. The Belgian plan assets are invested in certain individualized fixed income insurance contracts for the benefit of each plan participant as required by the local regulators and are therefore a Level 3 input. The United Kingdom plan assets consist of marketable securities which are Level 1 inputs because they trade in active markets.

We regularly review our actual asset allocation for each plan, and will periodically rebalance the investments in each plan to more accurately reflect the targeted allocation and/or maximize the overall long-term return when considered appropriate.

The composition of our December 31, 2011 and 2012 pension plan assets by fair value level is shown in the table below. The amounts shown for plan assets invested in the CMRT include a nominal amount of cash held by our U.S. pension plan which is not part of the plan’s investment in the CMRT.

Postretirement benefits other than pensions (OPEB)—We provide certain health care and life insurance benefits for eligible retired employees. Certain of our Canadian employees may become eligible for such postretirement health care and life insurance benefits if they reach retirement age while working for us. In the U.S., employees who retired after 1998 are not entitled to any such benefits. The majority of all retirees are required to contribute a portion of the cost of their benefits and certain current and future retirees are eligible for reduced health care benefits at age 65. We have no OPEB plan assets, rather, we fund medical claims as they are paid. Contribution to our OPEB plans to cover benefit payments are expected to be the equivalent of:

The amounts shown in the table above for net actuarial losses and prior service credit at December 31, 2011 and 2012 have not yet been recognized as components of our periodic OPEB cost as of those dates. These amounts will be recognized as components of our periodic OPEB cost in future years and are recognized, net of deferred income taxes, in our accumulated other comprehensive income (loss). We expect to recognize approximately $.3 million of unrecognized actuarial losses and $.6 million of prior service credit as components of our periodic OPEB cost in 2013.

At December 31, 2012, the accumulated OPEB obligations for all OPEB plans was comprised of $1.1 million related to U.S. plans and $13.5 million related to our Canadian plan (2011—$1.2 million and $12.0 million, respectively).

In the fourth quarter of 2010, we amended our benefit formula for most participants of our plans effective January 1, 2011, resulting in a prior service credit of approximately $5.8 million as of December 31, 2010. Key assumptions including the health care cost trend rate as of December 31, 2010 now reflect these plan revisions to the benefit formula.

The components of our periodic OPEB costs are presented in the table below. The amounts shown below for amortization of prior service credit and recognized actuarial losses for 2010, 2011 and 2012 were recognized as components of our accumulated other comprehensive income (loss) at December 31, 2009, 2010 and 2011, respectively, net of deferred income taxes.

A summary of our key actuarial assumptions used to determine the net benefit obligation as of December 31, 2011 and 2012 are presented in the table below. The weighted average discount rate was determined using the projected benefit obligation as of such dates. The impact of assumed increases in future compensation levels does not have a material effect on the actuarial present value of the benefit obligation as substantially all of such benefits relate solely to eligible retirees, for which compensation is not applicable.


	2011			2012
Healthcare inflation:
Initial rate		8.0	%		7.0	%
Ultimate rate		5.0	%		5.0	%
Year of ultimate rate achievement		2018			2018
Weighted average discount rate		4.1	%		3.9	%

Assumed health care cost trend rates affect the amounts we report for health care plans. A one percent change in assumed health care trend rates would not have a material effect on the net periodic OPEB cost for 2012 or on the accumulated OPEB obligation at December 31, 2012.

The weighted average discount rate used in determining the net periodic OPEB cost for 2012 was 4.1% (2011 – 5.1%; 2010 – 5.8%). Such weighted average rate was determined using the projected benefit obligation as of the beginning of each year. The impact of assumed increases in future compensation levels does not have a material effect on the net periodic OPEB cost as substantially all of such benefits relate solely to eligible retirees, for which compensation is not applicable. The impact of the assumed rate of return on plan assets also does not have a material effect on the net periodic OPEB cost as there were no plan assets as of December 31, 2011 or 2012.

Variances from actuarially-assumed rates will result in additional increases or decreases in accumulated OPEB obligations, net periodic OPEB cost and funding requirements in future periods.

Note 13 – Stockholders’ equity:

Secondary public offering of common stock—In November 2010, we completed a secondary public offering of 17.94 million shares of our common stock in an underwritten offering for net proceeds of $337.6 million. The price to the public was $20.00 per share, and the underwriting discount was 5.75% (or $1.15 per share). Costs of the offering (exclusive of the underwriting discount) were approximately $.7 million. The offering took place in two parts, and the first closing occurred on November 2, 2010 of 15.6 million shares of common stock that generated net proceeds of $293.5 million. The second closing (upon exercise of the underwriters’ over-allotment option) occurred on November 9, 2010 for an additional 2.34 million shares of common stock that generated additional net proceeds of $44.1 million. The shares of common stock issued in the secondary offering are identical to the previously issued outstanding shares in all respects, including par value, liquidation and dividend preference. All shares were sold to third-party investors; none of our affiliated companies purchased any shares in the offering. Upon completion of the offering, the Valhi consolidated aggregate ownership of Kronos was reduced from 95.2% (59.2% held by Valhi directly and 36.0% held by NL directly) to 80.4% (50.0% is held by Valhi directly and 30.4% is held by NL directly).

NL common stock options held by our employees—Certain of our employees were granted nonqualified options to purchase NL common stock under the terms of certain option plans sponsored by NL. Generally, the stock options were granted at a price equal to or greater than 100% of the market price of NL’s common stock at the date of grant, vested over a five-year period and expired ten years from the date of grant. At December 31, 2012, no options were outstanding as all outstanding options expired or were exercised in 2011. During 2010 and 2011, 10,350 and 25,950 options were exercised, respectively. No options were issued during 2012.

Long-term incentive compensation plan—Prior to 2012, we had a long-term incentive compensation plan that provided for the discretionary grant of, among other things, qualified incentive stock options, nonqualified stock options, restricted common stock, stock awards and stock appreciation rights. Up to 150,000 shares of our common stock could be issued pursuant to this plan. During 2010, 2011 and 2012 we awarded an aggregate of 7,000, 3,500 and 4,500 shares, respectively, of our common stock pursuant to this plan to members of our board of directors. In February 2012, our board of directors voted to replace the existing long-term incentive plan with a new plan that would provide for the award of stock to our board of directors, and up to a maximum of 200,000 shares could be awarded. The new plan was approved at our May 2012 shareholder meeting and shortly thereafter the prior long-term incentive compensation plan terminated. No shares were awarded under this new plan in 2012, and 200,000 shares are available for future award under this new plan.

Stock split—In May 2011, we amended our certificate of incorporation to increase the authorized number of shares of our common stock from 60 million to 240 million. Also in May 2011, we implemented a 2-for-1 split of our common stock effected in the form of a stock dividend. Other than the disclosure of the authorized number of shares of our common stock discussed in this paragraph, we have adjusted all share and per-share disclosures for all periods presented in our consolidated financial statements to give effect to the stock split.

Special dividend—Cash dividends in 2011 include a $.50 per share special dividend paid to stockholders in the first quarter of 2011.

Stock repurchase program—In December 2010, our board of directors authorized the repurchase of up to 2.0 million shares of our common stock in open market transactions, including block purchases, or in privately-negotiated transactions at unspecified prices and over an unspecified period of time. We may repurchase our common stock from time to time as market conditions permit. The stock repurchase program does not include specific price targets or timetables and may be suspended at any time. Depending on market conditions, we may terminate the program prior to its completion. We would use cash on hand or other sources of liquidity to acquire the shares. Repurchased shares will be added to our treasury and cancelled. To date, we have not made any repurchases under the plan and all 2.0 million shares are available for repurchase.

Related party transactions

Note 14—Related party transactions:

We may be deemed to be controlled by Harold C. Simmons. See Note 1. Corporations that may be deemed to be controlled by or affiliated with Mr. Simmons sometimes engage in (a) intercorporate transactions such as guarantees, management and expense sharing arrangements, shared fee arrangements, joint ventures, partnerships, loans, options, advances of funds on open account, and sales, leases and exchanges of assets, including securities issued by both related and unrelated parties and (b) common investment and acquisition strategies, business combinations, reorganizations, recapitalizations, securities repurchases, and purchases and sales (and other acquisitions and dispositions) of subsidiaries, divisions or other business units, which transactions have involved both related and unrelated parties and have included transactions which resulted in the acquisition by one related party of a publicly-held noncontrolling interest in another related party. While no transactions of the type described above are planned or proposed with respect to us other than as set forth in these financial statements, we continuously consider, review and evaluate, and understand that Contran and related entities consider, review and evaluate such transactions. Depending upon the business, tax and other objectives then relevant, it is possible that we might be a party to one or more such transactions in the future.

Current receivables from and payables to affiliates are summarized in the table below.


	December 31,
	2011		2012
	(In millions)
Current receivable from affiliate—LPC	$	29.6	$	—

Noncurrent note receivable from Valhi	$	136.1	$	—

Current payables to affiliates:
LPC	$	—	$	23.5
Income taxes payable to Valhi		8.6		18.1

Total	$	8.6	$	41.6

From time to time, we will have loans and advances outstanding between us and various related parties pursuant to term and demand notes. We generally enter into these loans and advances for cash management purposes. When we loan funds to related parties, we are generally able to earn a higher rate of return on the loan than we would earn if we invested the funds in other instruments, and when we borrow from related parties, we are generally able to pay a lower rate of interest than we would pay if we had incurred third-party indebtedness. While certain of these loans to affiliates may be of a lesser credit quality than cash equivalent instruments otherwise available to us, we believe we have considered the credit risks in the terms of the applicable loans. In this regard:

•

In November 2010, we entered into an unsecured revolving demand promissory note with Valhi whereby, as amended, we have agreed to loan Valhi up to $100 million ($225 million at December 31, 2011). Our loan to Valhi bears interest at prime plus 1.00%, payable quarterly, with all principal due on demand, but in any event no earlier than December 31, 2014. The amount of our outstanding loans to Valhi at any time is at our discretion. As of December 31, 2012, we had no outstanding loans to Valhi under this promissory note (2011—$136.1 million);

•

In April 2010, we entered into an unsecured revolving credit note with Contran pursuant to which we could borrow up to $40 million from Contran. Such revolving credit note terminated upon its maturity in December 2011; and

•

In February 2013, we borrowed $190 million from Contran under the provisions of a new loan described in Note 9.

Interest income on our loan to Valhi was $.5 million in 2010, $3.7 million in 2011 and $7.1 million in 2012. Interest expense on our loans from Contran was $.2 million in 2010 and nil in 2011.

Amounts payable to LPC are generally for the purchase of TiO₂, while amounts receivable from LPC are generally from the sale of TiO₂ feedstock. See Note 5. Purchases of TiO₂ from LPC were $133.7 million in 2010, $144.8 million in 2011 and $250.2 million in 2012. Sales of feedstock to LPC were $5.2 million in 2010, $93.0 million in 2011 and $143.7 million in 2012.

Under the terms of various intercorporate services agreements (ISAs) entered into between us and various related parties, including Contran, employees of one company will provide certain management, tax planning, financial and administrative services to the other company on a fee basis. Such charges are based upon estimates of the time devoted by the employees of the provider of the services to the affairs of the recipient, and the compensation and associated expenses of such persons. Because of the large number of companies affiliated with Contran, we believe we benefit from cost savings and economies of scale gained by not having certain management, financial and administrative staffs duplicated at each entity, thus allowing certain individuals to provide services to multiple companies but only be compensated by one entity. The net ISA fee charged to us, approved by the independent members of our board of directors, is included in selling, general and administrative expense and corporate expense and was $8.3 million in 2010, $9.6 million in 2011 and $11.2 million in 2012. This agreement is renewed annually and we expect to pay approximately $12.9 million under the ISA during 2013.

Tall Pines Insurance Company and EWI RE, Inc. provide for or broker certain insurance policies for Contran and certain of its subsidiaries and affiliates, including ourselves. Tall Pines and EWI are subsidiaries of Valhi. Consistent with insurance industry practices, Tall Pines and EWI receive commissions from insurance and reinsurance underwriters and/or assess fees for the policies that they provide or broker. The aggregate premiums paid to Tall Pines and EWI by us and our joint venture were $8.0 million in 2010, $9.5 million in 2011 and $12.0 million in 2012. These amounts principally included payments for insurance and reinsurance premiums paid to third parties, but also included commissions paid to Tall Pines and EWI. Tall Pines purchases reinsurance from third-party insurance carriers with an A.M. Best Company rating of generally at least A- (excellent) for substantially all of the risks it underwrites. We expect these relationships with Tall Pines and EWI will continue in 2013.

Contran and certain of its subsidiaries and affiliates, including us, purchase certain of their insurance policies as a group, with the costs of the jointly-owned policies being apportioned among the participating companies. With respect to certain of such policies, it is possible that unusually large losses incurred by one or more insureds during a given policy period could leave the other participating companies without adequate coverage under that policy for the balance of the policy period. As a result, Contran and certain of its subsidiaries and affiliates, including us, have entered into a loss sharing agreement under which any uninsured loss is shared by those entities who have submitted claims under the relevant policy. We believe the benefits, in the form of reduced premiums and broader coverage associated with the group coverage for such policies, justifies the risk associated with the potential for any uninsured loss.

Commitments and contingencies

Commitments and contingencies

Note 15—Commitments and contingencies:

Environmental matters—Our operations are governed by various environmental laws and regulations. Certain of our operations 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 facilities and to strive to improve our environmental performance. From time to time, we may be subject to environmental regulatory enforcement under U.S. and non-U.S. statutes, 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 thereunder, could adversely affect our production, handling, use, storage, transportation, sale or disposal of such substances. We believe all of our plants are in substantial compliance with applicable environmental laws.

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

In March 2010, we were served with two complaints which were subsequently consolidated as Haley Paint et al. v. E.I. Du Pont de Nemours and Company, et al. (United States District Court, for the District of Maryland, Case No. 1:10-cv-00318-RDB). A third plaintiff intervened into the current case in July 2011. The defendants include us, E.I. Du Pont de Nemours & Company, Huntsman International LLC, Millennium Inorganic Chemicals, Inc. and the National Titanium Dioxide Company Limited (d/b/a Cristal). Plaintiffs seek to represent a class consisting of all persons and entities that purchased titanium dioxide in the United States directly from one or more of the defendants on or after March 1, 2002. The complaint alleges that the defendants conspired and combined to fix, raise, maintain, and stabilize the price at which titanium dioxide was sold in the United States and engaged in other anticompetitive conduct. In May 2010, defendants filed a motion to dismiss, which plaintiffs opposed. In March 2011, the court denied the motion to dismiss. In February 2012, the plaintiffs submitted their motion for class certification, which defendants opposed. In August 2012, the court granted the plaintiffs’ motion for class certification and trial is currently set for September 2013. The case is proceeding in the trial court. We believe the action is without merit, have denied all allegations of wrongdoing and liability and intend to defend against the action vigorously.

Concentrations of credit risk—Sales of TiO₂ accounted for approximately 90% of our sales in 2010, 92% in 2011 and 90% in 2012. The remaining sales result from the mining and sale of ilmenite ore (a raw material used in the sulfate pigment production process), and the manufacture and sale of iron-based water treatment chemicals and certain titanium chemical products (derived from co-products of the TiO₂ production processes). TiO₂ is generally sold to the paint, plastics and paper industries. Such markets are generally considered “quality-of-life” markets whose demand for TiO₂ is influenced by the relative economic well-being of the various geographic regions. We sell TiO₂ to over 4,000 customers, with the top ten customers approximating 27% of net sales in 2010, 30% in 2011 and 34% in 2012. We did not have sales to a single customer comprising over 10% of our net sales in 2010 or 2011. In 2012, one customer, Behr Process Corporation, did account for approximately 10% of our net sales. The table below shows the approximate percentage of our TiO₂ sales by volume for our significant markets, Europe and North America, for the last three years.


	2010			2011			2012
Europe		53	%		53	%		47	%
North America		33	%		32	%		35	%

Long-term contracts—We have long-term supply contracts that provide for certain of our TiO₂ feedstock requirements through 2016. The agreements require us to purchase certain minimum quantities of feedstock with minimum purchase commitments aggregating approximately $1.8 billion over the life of the contracts in years subsequent to December 31, 2012. In addition, we have other long-term supply and service contracts that provide for various raw materials and services. These agreements require us to purchase certain minimum quantities or services with minimum purchase commitments aggregating approximately $122 million at December 31, 2012.

Operating leases—Our principal German operating subsidiary leases the land under its Leverkusen TiO₂ production facility pursuant to a lease with Bayer AG that expires in 2050. The Leverkusen facility itself, which we own and which represents approximately one-third of our current TiO₂ production capacity, is located within Bayer’s extensive manufacturing complex. We periodically establish the amount of rent for the land lease associated with the Leverkusen facility by agreement with Bayer for periods of at least two years at a time. The lease agreement provides for no formula, index or other mechanism to determine changes in the rent for such land lease; rather, any change in the rent is subject solely to periodic negotiation between Bayer and us. We recognize any change in the rent based on such negotiations as part of lease expense starting from the time such change is agreed upon by both parties, as any such change in the rent is deemed “contingent rentals” under GAAP. Under various supply and services agreements certain majority-owned subsidiaries of Bayer provide raw materials, including chlorine, auxiliary and operating materials, utilities and services necessary to operate the Leverkusen facility. In March 2013 we anticipate entering into a new long-term master agreement expiring in 2017 with a majority-owned subsidiary of Bayer which agreement will set forth the master terms and conditions for the separate supply and services agreements.

We also lease various other manufacturing facilities and equipment. Some of the leases contain purchase and/or various term renewal options at fair market and fair rental values, respectively. In most cases we expect that, in the normal course of business, such leases will be renewed or replaced by other leases. Net rent expense approximated $11 million in 2010, $13 million in 2011 and $16 million in 2012. At December 31, 2012, future minimum payments under noncancellable operating leases having an initial or remaining term of more than one year were as follows:


Years ending December 31,	Amount
	(In millions)
2013	$	12.2
2014		8.5
2015		5.5
2016		3.5
2017		2.6
2018 and thereafter		23.6

Total	$	55.9

Approximately $18 million of the $55.9 million aggregate future minimum rental commitments at December 31, 2012 relates to our Leverkusen facility lease discussed above. The minimum commitment amounts for such lease included in the table above for each year through the 2050 expiration of the lease are based upon the current annual rental rate as of December 31, 2012. As discussed above, any change in the rent is based solely on negotiations between Bayer and us, and any such change in the rent is deemed “contingent rentals” under GAAP which is excluded from the future minimum lease payments disclosed above.

Income taxes—We and Valhi have agreed to a policy providing for the allocation of tax liabilities and tax payments as described in Note 1. Under applicable law, we, along with every other member of the Contran Tax Group, are each jointly and severally liable for the aggregate federal income tax liability of Contran and the other companies included in the Contran Tax Group for all periods in which we are included in the Contran Tax Group.

Financial Instruments

Note 16—Financial instruments:

The following table summarizes the valuation of our financial instruments recorded on a fair value basis as of December 31, 2011 and 2012:


	Fair Value Measurements
	Total			Quoted Prices in Active Markets (Level 1)			Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
	(In millions)
Asset (liability)
December 31, 2011
Currency forward contracts	$	(.8	)	$	(.8	)	$	—	$	—
Current marketable securities (See Note 6)		20.9			20.9			—		—
Noncurrent marketable securities (See Note 6)		98.4			98.4			—		—
December 31, 2012
Currency forward contracts	$	1.8		$	1.8		$	—	$	—
Noncurrent marketable securities (See Note 6)		21.6			21.6			—		—

Certain of our sales generated by our non-U.S. operations are denominated in U.S. dollars. We periodically use currency forward contracts to manage a very nominal portion of currency exchange rate risk associated with trade receivables denominated in a currency other than the holder’s functional currency or similar exchange rate risk associated with future sales. We have not entered into these contracts for trading or speculative purposes in the past, nor do we currently anticipate entering into such contracts for trading or speculative purposes in the future. Derivatives used to hedge forecasted transactions and specific cash flows associated with financial assets and liabilities denominated in currencies other than the U.S. dollar and which meet the criteria for hedge accounting are designated as cash flow hedges. Consequently, the effective portion of gains and losses is deferred as a component of accumulated other comprehensive income and is recognized in earnings at the time the hedged item affects earnings. Contracts that do not meet the criteria for hedge accounting are marked-to-market at each balance sheet date with any resulting gain or loss recognized in income currently as part of net currency transactions. The fair value of the currency forward contracts is determined using Level 1 inputs based on the currency spot forward rates quoted by banks or currency dealers.

At December 31, 2012, we had currency forward contracts to exchange an aggregate $20.0 million for an equivalent value of Norwegian kroner at exchange rates ranging from kroner 6.02 to kroner 6.13 per U.S. dollar. These contracts with DnB Nor Bank ASA mature at a rate of $5.0 million per month in certain months from January 2013 through May 2013. At December 31, 2011, we had currency forward contracts to exchange an aggregate of $48.0 million for an equivalent value of Canadian dollars at exchange rates ranging from Cdn. $.9969 to Cdn. $1.0283 per U.S. dollar. These contracts with Wells Fargo Bank, National Association matured from January 2012 to December 2012 at a rate of $4.0 million per month, subject to early redemption at our option.

The estimated fair value of such currency forward contracts at December 31, 2012 was a $1.8 million net asset, which is recognized as part of Accounts and Other Receivables in our Consolidated Balance Sheet with a corresponding $1.8 million currency transaction gain in our Consolidated Statement of Operations (2011—$.8 million net liability, recognized as part of Accounts Payable and Accrued Liabilities, with a corresponding $.8 million currency transaction loss in our Consolidated Statement of Operations). We did not use hedge accounting for any of our contracts to the extent we held such contracts during 2010, 2011 and 2012.

The following table presents the financial instruments that are not carried at fair value but which require fair value disclosure as of December 31, 2011 and 2012.


	December 31, 2011				December 31, 2012
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
	(In millions)
Cash, cash equivalents and restricted cash	$	89.8	$	89.8	$	292.9	$	292.9

Notes payable and long-term debt:
Fixed rate with market quotes - 6.5% Senior Secured Notes		360.6		362.6		—		—
Variable rate:
European credit facility		—		—		13.2		13.2
Term loan		—		—		384.5		396.8
Common stockholders’ equity		924.3		2,090.9		1,062.1		2,260.2

At December 31, 2011, the estimated market price of the 6.5% Notes was approximately €1,004 per €1,000 principal amount. At December 31, 2012, the estimated market price of our term loan was $1,017.5 per $1,000 principal amount. The fair value of our 6.5% Notes and term loan is based on quoted market prices; however, these quoted market prices represent Level 2 inputs because the markets in which the Notes and term loan trade were not active. The fair value of our European credit facility represents a Level 2 input, and is deemed to approximate book value. The fair value of our common stockholders’ equity is based upon quoted market prices at each balance sheet date, which represent Level 1 inputs. Due to their near-term maturities, the carrying amounts of accounts receivable and accounts payable are considered equivalent to fair value. See Notes 1 and 6.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities.

Recent Accounting Standards

Note 17 – Recent accounting standards:

In June 2011 the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2011-05, Presentation of Comprehensive Income. ASU 2011-05 eliminates the option of presenting comprehensive income as a component of the Consolidated Statement of Stockholders’ Equity and instead requires comprehensive income to be presented as a component of the Consolidated Statement of Income or in a separate Consolidated Statement of Comprehensive Income immediately following the Consolidated Statement of Income. In accordance with ASU 2011-05, we now present our comprehensive income in a separate Consolidated Statement of Comprehensive Income. Additionally, ASU 2011-05 would have required us to present on the face of our financial statements the effect of reclassifications out of accumulative other comprehensive income on the components of net income and other comprehensive income. However, in December 2011 the FASB issued ASU 2011-12, Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05. ASU 2011-12 defers the effective date for the requirement to present on the face of our financial statements the effects of reclassifications out of accumulated other comprehensive income on the components of net income and other comprehensive income. Adoption of ASU 2011-05, as amended by ASU 2011-12, did not have a material effect on our Consolidated Financial Statements.

In February 2013 the FASB issued ASU 2013-02, Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income. ASU 2013-02 does not change current financial reporting requirements, instead an entity is required to cross-reference to other required disclosures that provide additional detail about amounts reclassified out of accumulated other comprehensive income. In addition, ASU 2013-02 requires an entity to present significant amounts reclassified out of accumulated other comprehensive income by line item of net income if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. Adoption of this standard is required for periods beginning after December 15, 2013; however, as permitted by the standard, we have elected to adopt ASU 2013-02 beginning with this report, see Note 13. The adoption of ASU 2013-02 did not have a material effect on our Consolidated Financial Statements.

In the second quarter of 2011, we recognized a $3.3 million pre-tax interest charge related to the partial redemption of our Senior Secured Notes. See Note 9.

Our provision for income taxes in the third and fourth quarters of 2011 includes $13.2 million and $4.0 million, respectively, for U.S. incremental income taxes on current earnings repatriated from our German subsidiary, which earnings were used to fund a portion of the repurchases of our Senior Secured Notes discussed in Note 9.

In the second quarter of 2012, we recognized a $7.2 million pre-tax interest charge related to the June redemption of our outstanding Senior Secured Notes. See Note 9.

In the fourth quarter of 2012, we recognized a $3.9 million pre-tax loss on the sale of TIMET stock. See Note 6.

Our provision for income taxes in the third quarter of 2012 includes an incremental tax benefit of $11.1 million as we determined during the third quarter that due to global changes in the business we would not remit certain dividends from non-U.S. jurisdictions. As a result, certain current year tax attributes were available for carryback to offset prior year tax expense. See Note 10.

Our provision for income taxes in the fourth quarter of 2012 includes an incremental tax of $8.0 million. During the fourth quarter as a result of a change in circumstances related to our sale and the sale by certain of our affiliates of their shares of TIMET common stock, which sale provided an opportunity for us and other members of our consolidated U.S. federal income tax group to elect to claim foreign tax credits, we determined that we could tax-efficiently remit non-cash dividends from our non-U.S. jurisdictions before the end of the year that absent the TIMET sale would not have been considered. Such incremental income tax recognized in the fourth quarter is the incremental income tax on the non-cash dividends remitted in the fourth quarter. Our provision for income taxes in the fourth quarter of 2012 also includes a $2.8 million expense related to a net increase in our reserve for uncertain tax positions. See Note 10. In addition, an aggregate $3.5 million of such fourth quarter 2012 provision for income taxes is a correction of amounts that should have been recognized in the third quarter of 2011 and is not material to any current or prior periods.

The sum of the quarterly per share amounts may not equal the annual per share amounts due to relative changes in the weighted average number of shares used in the per share computations.

- Definition

The entire disclosure for the quarterly financial data in the annual financial statements. The disclosure may include a tabular presentation of financial information for each fiscal quarter for the current and previous year, including revenues, gross profit, income or loss before extraordinary items and earnings per share data. It also includes an indication if the information in the note is unaudited, comments on the aggregate effect of year-end adjustments, and an explanation of matters or transactions that affect comparability or are pertinent to an understanding of the information furnished.

- Definition

1) For defined benefit pension plans, the benefit obligation is the projected benefit obligation, which is the actuarial present value as of a date of all benefits attributed by the pension benefit formula to employee service rendered prior to that date. 2) For other postretirement defined benefit plans, the benefit obligation is the accumulated postretirement benefit obligation, which is the actuarial present value of benefits attributed to employee service rendered to a particular date.

- Definition

Assets, usually stocks, bonds, and other investments, that have been segregated and restricted (usually in a trust) to provide benefits, at their fair value as of the measurement date. Plan assets include amounts contributed by the employer (and by employees for a contributory plan) and amounts earned from investing the contributions, less benefits paid. If a plan has liabilities other than for benefits, those non-benefit obligations may be considered as reductions of plan assets.
