Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 1 - Summary of significant accounting policies:

Organization and basis of presentation - At December 31, 2014, Valhi, Inc. (NYSE: VHI) held approximately 50% of our outstanding common stock and NL Industries, Inc. (NYSE: NL) held approximately 30% of our common stock, Valhi owned approximately 83% of NL’s outstanding common stock and a wholly-owned subsidiary of Contran Corporation held approximately 93% of Valhi’s outstanding common stock. Substantially all of Contran’s outstanding voting stock is held by family trusts established for the benefit of Lisa K. Simmons and Serena Simmons Connelly, daughters of Harold C. Simmons, and their children (for which Ms. Lisa Simmons and Ms. Connelly are co-trustees) or is held directly by Ms. Lisa Simmons and Ms. Connelly or persons or entities related to them, including their step-mother Annette C. Simmons, the widow of Mr. Simmons. Prior to his death in December 2013, Mr. Simmons served as sole trustee of the family trusts. Under a voting agreement entered into by all of the voting stockholders of Contran, effective in February 2014 and as amended, the size of the board of directors of Contran was fixed at five members, Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons (and in the event of their death, their heirs) each has the right to designate one of the five members of the Contran board and the remaining two members of the Contran board must consist of members of Contran management. Ms. Lisa Simmons, Ms. Connelly, and Ms. Annette Simmons each serve as members of the Contran board. The voting agreement expires in February 2017 (unless Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons otherwise unanimously agree), and the ability of Ms. Lisa Simmons, Ms. Connelly, and Ms. Annette Simmons to each designate one member of the Contran board is dependent upon each of their continued beneficial ownership of at least 5% of the combined voting stock of Contran. Consequently, Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons may be deemed to control Contran, Valhi, NL 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 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 $1.1 million in 2012, $1.5 million in 2013 and $2.9 million in 2014. 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. 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 $32.1 million in 2012, $24.2 million in 2013 and $8.2 million in 2014.

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 $659 million at December 31, 2014. 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. 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 $89 million in 2012, $93 million in 2013 and $95 million in 2014. We expense research, development and certain sales technical support costs as incurred and these costs approximated $19 million in 2012, $18 million in 2013 and $19 million in 2014. We expense advertising costs as incurred and these costs were not material in any year presented.

Geographic Information

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, TiO₂is 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, 2013 and 2014 the net assets of non-U.S. subsidiaries included in consolidated net assets approximated $492 million and $380 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.

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 LLC (Tioxide). Tioxide is a 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.

Marketable Securities

Note 6 - Marketable securities:

Our marketable securities consist of investments in the publicly-traded shares of related parties: Valhi, NL and CompX International Inc. 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.

NL and CompX common stocks	1		.1			.1			-
Total		$	11.1		$	15.4		$	(4.3	)

At December 31, 2013 and 2014, we held approximately 1.7 million shares of Valhi’s common stock, which we purchased prior to 2012. We also held a nominal number of shares of CompX and NL common stocks. At December 31, 2013 and 2014, the quoted per share market price of Valhi’s common stock was $17.58 and $6.41, respectively.

With respect to our investment in Valhi stock, our cost basis has exceeded its market value since March 2014, but we consider such decline in market price to be temporary at December 31, 2014. We considered all available evidence in reaching this conclusion, including our ability and intent to hold this investment for a reasonable period of time sufficient for the recovery of fair value, as evidenced by the amount of liquidity we currently have with cash on hand. We will continue to monitor the quoted market price for this investment. In this regard, as of February 27, 2015, the aggregate quoted market price for our shares of Valhi common stock was $4.5 million less than our aggregate cost basis. If we conclude in the future that a decline in value of one or more of these securities was other than temporary, we would recognize impairment through an income statement charge at that time. Such income statement impairment charge would be offset in other comprehensive income by the reversal of the previously recognized unrealized losses to the extent they were previously recognized in accumulated other comprehensive income.

Prior to December 31, 2012, we held approximately 4.2 million shares, or 2.4%, of Titanium Metals Corporation’s (TIMET) outstanding common stock, which we purchased prior to 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 General Corporation Law, but we do receive dividends from Valhi on these shares, when declared and paid.

Term loans - In 2013, we voluntarily repaid our entire $400 million term loan that was issued in June 2012. We prepaid an aggregate $290 million principal amount in February 2013 and recognized a non-cash pre-tax interest charge of $6.6 million in the first quarter of 2013 related to this prepayment consisting of the write-off of the unamortized original issue discount costs and deferred financing costs associated with such prepayment. Funds for such prepayment were provided by $100 million of our cash on hand as well as borrowings of $190 million under a 2013 loan agreement from Contran as described below. In July 2013, we voluntarily prepaid the remaining $100 million principal amount outstanding under such term loan, using $50 million of our cash on hand and borrowings of $50 million under our revolving North American credit facility. We recognized a non-cash pre-tax interest charge of $2.3 million in the third quarter of 2013 related to this prepayment consisting of the write-off of the unamortized original issue discount costs and deferred financing costs associated with such prepayment.

In February 2014, we entered into a new $350 million term loan. The term loan was issued at 99.5% of the principal amount, or an aggregate of $348.3 million. We used $170 million of the net proceeds of the new term loan to prepay the outstanding principal balance of our note payable to Contran (along with accrued and unpaid interest through the prepayment date), and such note payable was cancelled. The remaining net proceeds of the term loan are available for our general corporate purposes. The new term loan:

·	bears interest, at our option, at LIBOR (with LIBOR no less than 1.0%) plus 3.75%, or the base rate, as defined in the agreement, plus 2.75%;

requires quarterly principal repayments of $875,000 which commenced in June 2014, other mandatory principal repayments of formula-determined amounts under specified conditions with all remaining principal balance due in February 2020. Voluntary principal prepayments are permitted at any time, provided that a call premium of 1% of the principal amount of such prepayment applies to any voluntary prepayment made on or before February 2015 (there is no prepayment penalty applicable to any voluntary prepayment after February 2015). We made no such voluntary prepayments through February 2015;

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 $395.7 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 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 (however, there are no ongoing financial maintenance covenants); and

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

The average interest rate on the term loan borrowings as of and for the period from issuance to December 31, 2014 was 4.75%. The carrying value of the term loan at December 31, 2014 includes unamortized original issue discount of $1.5 million.

Note payable to Contran - As discussed above, in February 2013 we entered into a promissory note with Contran. This loan from Contran contained terms and conditions similar to the terms and conditions of our prior $400 million term loan, except that the loan from Contran was unsecured and contained no ongoing financial maintenance covenant. The independent members of our board of directors approved the terms and conditions of the loan from Contran. In 2013, we borrowed $190 million and subsequently repaid $20 million. As discussed above, in February 2014 we used $170 million of the proceeds from our new term loan and prepaid the remaining balance owed to Contran under this note payable (without penalty), and the note payable to Contran was cancelled.

Senior Secured Notes - In 2012, we redeemed the remaining €279.2 million principal amount of our Senior Secured Notes that were outstanding, and recognized an aggregate $7.2 million pre-tax charge related to such early extinguishment 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 their redemption.

Revolving credit facilities

Revolving North American credit facility - In June 2012, we entered into a $125 million revolving bank credit facility which matures in 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 1.1 to 1.0. During 2014, we borrowed $81.0 million and repaid $92.1 million under this facility. The average interest rate on outstanding borrowings for the year-to-date period ended February 18, 2014 when the outstanding balance was repaid was 3.75%. At December 31, 2014 we had approximately $94.2 million available for borrowing under this revolving facility.

Revolving European credit facility - Our operating subsidiaries in Germany, Belgium, Norway and Denmark have a €120 million secured revolving bank credit facility that 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.

We had no borrowings or repayments under this facility during 2014. At December 31, 2014, there were no outstanding borrowings under this facility. Our European revolving credit facility requires the maintenance of certain financial ratios, and one of such requirements is based on the ratio of net debt to last twelve months earnings before income tax, interest, depreciation and amortization expense (EBITDA) of the borrowers. Based upon the borrowers’ last twelve months EBITDA as of December 31, 2014 and the net debt to EBITDA financial test, our borrowing availability at December 31, 2014 is approximately 54% of the credit facility, or €65 million ($79 million).

Canada - 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 have borrowed an aggregate of Cdn. $3.0 million through December 31, 2014. We borrowed an additional Cdn. $1.5 million under this facility in January 2015 (and no additional amounts are expected to be borrowed under this facility). 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 2018. 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, 2014, we had Cdn. $3.0 million (USD $2.6 million), outstanding under this agreement.

Prior to December 31, 2014, we had an aggregate of Cdn. $7.9 million of letters of credit outstanding issued by a bank on behalf of our Canadian subsidiary. These letters of credit were issued in connection with the appeal of a Canadian income tax assessment discussed in Note 10. Upon the successful completion of the appeal in 2014, such letters of credit were cancelled, and an equivalent amount of restricted cash deposits which had been collateralizing such letters of credit, classified as noncurrent restricted cash, were released (See Note 7).

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 2013 and 2014, our French subsidiary distributed no dividends. At December 31, 2014, our French subsidiary has undistributed earnings of approximately $12.8 million that, if distributed, would be subject to the 3% surtax. We also accrue U.S. incremental income taxes on earnings of non-U.S. subsidiaries which we have determined are not permanently reinvested.

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 objected to the re-assessments and believed the position was without merit. Accordingly, we appealed the re-assessments and in connection with such appeal we were required to post letters of credit aggregating Cdn. $7.9 million (see Note 9). In the second quarter of 2014, the Appeals Division of the Canadian Revenue Authority ruled in our favor and reversed in their entirety such notices of re-assessment. As a result, we recognized a non-cash income tax benefit of $3.0 million related to the release of a portion of our reserve for uncertain tax positions in the second quarter of 2014 related to the completion of this Canadian income tax audit. In addition, the related letters of credit have been cancelled (see Note 9). Also during the second quarter of 2014, we recognized a non-cash income tax benefit of $3.1 million related to the release of a portion of our reserve for uncertain tax positions in conjunction with the completion of an audit of our U.S. income tax return for 2009. 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 2012, 2013 and 2014 was not material, and at December 31, 2012, 2013 and 2014, we had $3.4 million, $3.7 million and $2.8 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 discussed above) during 2012, 2013 and 2014:

	Years ended December 31,
	2012			2013			2014

Change in currency exchange rates		.3			(.7	)		(1.2	)
Unrecognized tax benefits at end of year	$	13.0		$	15.9		$	10.4

If our uncertain tax positions were recognized, a benefit of $16.4 million, $15.1 million and $8.8 million would affect our effective income tax rates for 2012, 2013 and 2014 respectively. At December 31, 2014, we currently estimate that our unrecognized tax benefits will not change materially during the next twelve months related to our prior year returns.

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 2011 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 2010 for Germany, 2011 for Belgium, 2009 for Canada and 2005 for Norway.

At December 31, 2014, we had the equivalent of $738 million and $94 million of net operating loss carryforwards for German corporate and trade tax purposes, respectively and we had the equivalent of $87 million of net operating loss carryforwards for Belgian corporate tax purposes. At December 31, 2014, 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, if we generate operating losses in our German and Belgian 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.

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 $1.6 million in 2012, $1.8 million in 2013 and $2.6 million in 2014.

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. Certain non-U.S. employees are covered by plans in their respective countries. Our U.S. plan was closed to new participants in 1996, and existing participants no longer accrued any additional benefits after that date. 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 $18.8 million to all of our defined benefit pension plans during 2015. Benefit payments to plan participants out of plan assets are expected to be the equivalent of:

The components of our net periodic defined benefit pension cost for our non-U.S. defined benefit pension plans are presented in the table below. In December 2013, we amended one of our Canadian plans in which participation with respect to hourly workers was closed to new participants in December 2013, and existing hourly plan participants will no longer accrue additional benefits after December 2013, resulting in a $7.1 million curtailment charge for recognition of previously unamortized prior service cost and transition obligation and $.2 million for special termination benefits. In 2014, we amended the other Canadian plan in which participation with respect to salaried workers was closed to new participants in December 2014, and existing hourly plan participants will no longer accrue additional benefits after December 2014, resulting in a nominal curtailment charge. The amounts shown below for the amortization of prior service cost, net transition obligations and recognized actuarial losses for 2012, 2013 and 2014 were recognized as components of our accumulated other comprehensive income (loss) at December 31, 2011, 2012 and 2013, respectively, net of deferred income taxes.

At December 31, 2013 and 2014, 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. Prior to his death in December 2013, Mr. Simmons was the sole trustee of the CMRT, and he along with the CMRT’s investment committee, of which Mr. Simmons was a member, actively managed the investments of the CMRT. The CMRT’s long-term investment objective was 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 (prior to his death). During the history of the CMRT from its inception in 1988 through December 31, 2013, the average annual rate of return was 14%. For the years ended December 31, 2012 and 2013, 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 relied on the historical rates of return achieved by the CMRT, although we considered other factors as well including, among other things, the investment objectives of the CMRT’s managers and their expectation that such historical returns would in the future continue to be achieved over the long-term.

Following the death of Mr. Simmons in December 2013, the Contran board of directors in January 2014 appointed a financial institution as the new directed trustee of the CMRT, and the Contran board appointed five individuals (all executive officers of Contran) as the new investment committee of the CMRT. The new investment committee is in the process of reallocating to current and/or new investment managers or various mutual funds and comingled funds the portion of the CMRT assets that had previously been under direct and active management by Mr. Simmons. Such reallocation will be done prudently over a period of time, given the diverse asset composition of this portion of the portfolio. Concurrent with this change in investment strategy in which there is no longer a portion of the CMRT’s assets under direct and active management by Mr. Simmons, and considering the long-term asset mix of the assets of the CMRT and the expected long-term rates of return for such asset components as well as advice from Contran’s actuaries, beginning in 2014 the assumed long-term rate of return for plan assets invested in the CMRT was reduced to 7.5%.

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% and 80% of the assets of the CMRT at December 31, 2013 and 2014, respectively, 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,
	2013					2014

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 45% to equity securities, 47% to fixed income securities, 8% to other investments and 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 11% to equity securities, 79% to fixed income securities, 7% 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 6%, 3%, 5% and 4%, 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, 2013 and 2014 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, 2013 and 2014 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 $.9 million of prior service credit as components of our periodic OPEB cost in 2015.

At December 31, 2014, the accumulated OPEB obligations for all OPEB plans comprised $.7 million related to U.S. plans and $7.8 million related to our Canadian plan (2013 - $.9 million and $7.3 million, respectively).

In the fourth quarter of 2013, we amended the benefit formula for most Canadian participants of our plans effective January 1, 2014, resulting in a curtailment gain as of December 31, 2013. Key assumptions including the service cost and benefit duration as of December 31, 2013 and 2014 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 2012, 2013 and 2014 were recognized as components of our accumulated other comprehensive income (loss) at December 31, 2011, 2012 and 2013, respectively, net of deferred income taxes.

A summary of our key actuarial assumptions used to determine the net benefit obligation as of December 31, 2013 and 2014 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.

Healthcare inflation:
Initial rate		7.0	%		7.0	%
Ultimate rate		5.0	%		5.0	%
Year of ultimate rate achievement		2020			2021
Weighted average discount rate		4.6	%		3.7	%

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 2014 or on the accumulated OPEB obligation at December 31, 2014.

The weighted average discount rate used in determining the net periodic OPEB cost for 2014 was 4.6% (2013 - 3.9%; 2012 - 4.1%). 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, 2013 or 2014.

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.

Equity [Abstract]

Stockholders' Equity

Note 13 - Stockholders’ equity:

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 2012 we awarded an aggregate of 4,500 shares 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. We awarded 7,000 and 8,000 shares, respectively, under this new plan in 2013 and 2014, and 185,000 shares are available for future award under this new plan at December 31, 2014.

Stock repurchase program – Prior to 2012, 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.

During 2013 we repurchased 49,000 shares in market transactions for an aggregate of $.7 million in cash. We cancelled these treasury shares and allocated their cost to common stock at par value and additional paid-in capital. At December 31, 2014 an additional 1,951,000 shares are available for repurchase under this authorization.

The marketable securities reclassification adjustment in 2012, all of which was reclassified into net income, consists principally of the securities transaction loss related to the sale of TIMET common stock discussed in Note 6. See Note 11 for amounts related to our defined benefit pension plans and OPEB plans.

Related Party Transactions

Note 14 - Related party transactions:

We may be deemed to be controlled by Ms. Lisa Simmons, Ms. Connelly and Ms. Annette Simmons. See Note 1. Corporations that may be deemed to be controlled by or affiliated with such individuals sometimes engage in (a) intercorporate transactions such as guarantees, management and expense sharing arrangements, shared fee arrangements, joint ventures, partnerships, loans, options, advances of funds on open account, and sales, leases and exchanges of assets, including securities issued by both related and unrelated parties and (b) common investment and acquisition strategies, business combinations, reorganizations, recapitalizations, securities repurchases, and purchases and sales (and other acquisitions and dispositions) of subsidiaries, divisions or other business units, which transactions have involved both related and unrelated parties and have included transactions 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,
	2013		2014
	(In millions)
Current receivable from affiliate:
LPC	$	14.2	$	13.0
Income taxes receivable from Valhi		-		3.5

	$	14.2	$	18.0
Current payables to affiliates:

Income taxes payable to Valhi		.5		-
Other		.1		-
Total	$	21.7	$	19.9

Note payable to Contran - noncurrent	$	170.0	$	-

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. 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, 2016. The amount of our outstanding loans to Valhi at any time is at our discretion. As of December 31, 2013 and 2014, we had no outstanding loans to Valhi under this promissory note; and

—

In February 2013, we entered into a promissory note with Contran in which we borrowed $190 million on this note and subsequently repaid $20 million during 2013. We prepaid and cancelled this note payable to Contran in February 2014 using a portion of the net proceeds of our new term loan. See Note 9.

Interest income (including unused commitment fees) on our loan to Valhi was $7.1 million in 2012, $.5 million in 2013 and $.5 million in 2014. Interest expense on our loan from Contran was $11.7 million in 2013 and $1.6 million in 2014.

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 $250.2 million in 2012, $224.5 million in 2013 and $193.1 million in 2014. Sales of feedstock to LPC were $143.7 million in 2012, $141.1 million in 2013 and $98.4 million in 2014.

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 $11.2 million in 2012, $12.9 million in 2013 and $12.3 million in 2014. This agreement is renewed annually and we expect to pay approximately $13.4 million under the ISA during 2015.

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 $12.0 million in 2012, $11.3 million in 2013 and $10.7 million in 2014. 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 2015.

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 Disclosure [Abstract]

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, 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 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 2013 we entered into a settlement agreement with the class plaintiffs in the consolidated complaint, 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). Without admitting any fault or wrongdoing, we agreed to pay an aggregate of $35 million (which was paid in 2014), and we and the other defendants have been dismissed with prejudice from this matter. Other operating expense in 2013 includes a $35 million charge related to this settlement.

In March 2013, we were served with the complaint, Los Gatos Mercantile, Inc. d/b/a Los Gatos Ace Hardware, et al v. E.I. Du Pont de Nemours and Company, et al. (United States District Court, for the Northern District of California, Case No. 3:13-cv-01180-SI). The defendants include us, E.I. Du Pont de Nemours & Company, Huntsman International LLC and Millennium Inorganic Chemicals, Inc. As amended by plaintiffs’ second amended complaint, plaintiffs seek to represent a class consisting of indirect purchasers of titanium dioxide in the states of Arizona, Arkansas, California, the District of Columbia, Florida, Kansas, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New Hampshire, New Mexico, New York, North Carolina, Oregon, South Carolina, Tennessee and Wisconsin that indirectly purchased titanium dioxide 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. The case is now proceeding in the trial court. We believe the action is without merit, will deny all allegations of wrongdoing and liability and intend to defend against the action vigorously.

In November 2013, we were served with the complaint, The Valspar Corporation, et al v. E.I. Du Pont de Nemours and Company, et al. (United States District Court, for the District of Minnesota, Case No. 1:13-cv-03214-RHK-L1B). 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). The plaintiff opted out of the settlement in the original lawsuit, 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) and filed its own lawsuit against the defendants. The complaint alleged 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 October 2014, the court granted our motion to transfer, and the case is now proceeding in the trial court in the United States District Court for the Southern District of Texas, Case No. 4:14-cv-01130. We believe the action is without merit, will deny 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 each of 2012, 2013 and 2014. 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 34% of net sales in both 2012 and 2013 and 35% in 2014. In each of 2012, 2013 and 2014 one customer, Behr Process Corporation, accounted 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.

	2012			2013			2014
Europe		47	%		49	%		50	%
North America		35	%		33	%		33	%

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 $532 million over the life of the contracts in years subsequent to December 31, 2014. 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 $164 million at December 31, 2014.

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 the terms of a master supply and services agreement, a majority-owned subsidiary of Bayer provides raw materials, including chlorine, auxiliary and operating materials, utilities and services necessary to operate the Leverkusen facility. This agreement, as amended, expires in 2017 and will automatically renew for successive three year terms until terminated by either party upon one year’s prior notice.

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 $16 million in 2012, $15 million in 2013 and $16 million in 2014. At December 31, 2014, future minimum payments under non-cancellable operating leases having an initial or remaining term of more than one year were as follows:

Years ending December 31,	Amount
	(In millions)
2015	$	9.7
2016		8.0
2017		4.7
2018		3.5
2019		3.2
2020 and thereafter		21.6
Total	$	50.7

Approximately $16 million of the $50.7 million aggregate future minimum rental commitments at December 31, 2014 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, 2014. 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. Valhi has agreed, however, to indemnify us for any liability for income taxes of the Contran Tax Group in excess of our tax liability computed in accordance with the tax allocation policy.

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, 2014, we had currency forward contracts to exchange:

an aggregate $37.0 million for an equivalent value of Norwegian kroner at exchange rates ranging from kroner 6.75 to kroner 7.11 per U.S. dollar. These contracts with DnB Nor Bank ASA mature at a rate of $2.7 million to $5.0 million per month in certain months from January 2015 through December 2015; and

·	an aggregate €31.7 million for an equivalent value of Norwegian kroner at exchange rates ranging from kroner 8.52 to kroner 8.81 per euro. These contracts with DnB Nor Bank ASA mature at a rate of €1.1 to €5.0 million per month in certain months from February 2015 through December 2015.

The estimated fair value of such currency forward contracts at December 31, 2014 was a $4.2 million net liability, of which $4.2 million is recognized as part of accounts payable and accrued liabilities in our Consolidated Balance Sheet, with a corresponding $4.2 million currency transaction loss in our Consolidated Statement of Operations (2013 - $1.0 million net liability, of which $.2 million was recognized as part of accounts and other receivables and $1.2 million was recognized as part of accounts payable and accrued liabilities in our Consolidated Balance Sheet, with a corresponding $1.0 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 2012, 2013 and 2014.

The following table presents the financial instruments that are not carried at fair value but which require fair value disclosure as of December 31, 2013 and 2014.

	December 31, 2013				December 31, 2014
	Carrying amount		Fair value		Carrying amount		Fair value
	(In millions)
Cash, cash equivalents and restricted cash	$	63.8	$	63.8	$	169.9	$	169.9

North American credit facility		11.1		11.1		-		-
Common stockholders' equity		935.1		2,207.2		781.1		1,508.7

At December 31, 2014, the estimated market price of our term loan was $983.1 per $1,000 principal amount. The fair value of our term loan was based on quoted market prices; however, these quoted market prices represented Level 2 inputs because the markets in which the term loan trades were not active. The fair values of our note payable to Contran and our European credit facility represent Level 2 inputs, and are 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. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Recent Accounting Pronouncements	Note 17 - Recent accounting pronouncements: In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606). This standard replaces existing revenue recognition guidance, which in many cases was tailored for specific industries, with a uniform accounting standard applicable to all industries and transactions. The new standard is effective for us beginning with the first quarter of 2017. Entities may elect to adopt ASU No. 2014-09 retrospectively for all periods for all contracts and transactions which occurred during the period (with a few exceptions for practical expediency) or retrospectively with a cumulative effect recognized as of the date of adoption. ASU No. 2014-09 is a fundamental rewriting of existing GAAP with respect to revenue recognition, and we are still evaluating the effect the Standard will have on our Consolidated Financial Statements. In addition, we have not yet determined the method we will use to adopt the Standard.

We recognized the following amounts during 2013:

o	a $6.6 million pre-tax charge related to the February voluntary prepayment of an aggregate $290 million principal amount of our term loan in the first quarter (see Note 9),

o	a $35 million pre-tax litigation settlement charge included in corporate expense in the third quarter (see Note 15),

o	a $2.3 million pre-tax charge related to the July voluntary prepayment of the remaining $100 million principal amount of our term loan in the third quarter (see Note 9),

pre-tax charges aggregating approximately $28 million consisting of unabsorbed fixed production and other costs as a result of the Canadian plant lockout in the third and fourth quarters of approximately $19 million, $7 million as a result of the pension curtailment charge discussed in Note 11, and $2 million for severance and other back-to-work expenses associated with reaching terms of the new Canadian collective bargaining agreement. Approximately $7 million of the costs (primarily related to unabsorbed fixed production costs) related to the third quarter of 2013 with the remaining costs recognized in the fourth quarter of 2013, and

o	a tax benefit in the fourth quarter of $3.9 million related to the utilization of certain current year U.S. losses.

In 2014 we recognized a non-cash income tax benefit of $5.7 million in the second quarter of 2014 related to a net reduction in our reserve for uncertain tax positions.

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.
