Organization and Basis of Presentation	'
	Note 1 - Organization and basis of presentation:
	Organization - We are a majority-owned subsidiary of Valhi, Inc. (NYSE: VHI). At September 30, 2013, Valhi held approximately 50% of our outstanding common stock and NL Industries, Inc. (NYSE: NL) held an additional 30% of our common stock. Valhi owns approximately 83% of NL’s outstanding common stock. Approximately 94% of Valhi’s outstanding common stock is held by Contran Corporation and its subsidiaries. Substantially all of Contran’s outstanding voting stock is held by trusts established for the benefit of certain children and grandchildren of Harold C. Simmons (for which Mr. Simmons is the sole trustee), or is held directly by Mr. Simmons or other persons or entities related to Mr. Simmons. Consequently, Mr. Simmons may be deemed to control Contran, Valhi and us.
	Basis of presentation - The unaudited Condensed Consolidated Financial Statements contained in this Quarterly Report have been prepared on the same basis as the audited Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2012 that we filed with the Securities and Exchange Commission (SEC) on March 12, 2013 (2012 Annual Report). In our opinion, we have made all necessary adjustments (which include only normal recurring adjustments) in order to state fairly, in all material respects, our consolidated financial position, results of operations and cash flows as of the dates and for the periods presented. We have condensed the Consolidated Balance Sheet and Statement of Stockholders’ Equity at December 31, 2012 contained in this Quarterly Report as compared to our audited Consolidated Financial Statements at that date, and we have omitted certain information and footnote disclosures (including those related to the Consolidated Balance Sheet at December 31, 2012) normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). Our results of operations for the interim periods ended September 30, 2013 may not be indicative of our operating results for the full year. The Condensed Consolidated Financial Statements contained in this Quarterly Report should be read in conjunction with our 2012 Consolidated Financial Statements contained in our 2012 Annual Report.
	Unless otherwise indicated, references in this report to “we,” “us” or “our” refer to Kronos Worldwide, Inc. and its subsidiaries (NYSE: KRO) taken as a whole.

Marketable Securities	'
	Note 4 - Marketable securities:
	Our marketable securities consist of investments in the publicly-traded shares of related parties: Valhi, NL and CompX International Inc. NL owns a 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 13. 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.

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

	Total long-term debt	$	378.9		$	203.3
	Term loan - In February 2013, we voluntarily prepaid an aggregate $290 million principal amount of our term loan. We 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 new loan from Contran as described below. In July 2013, we voluntarily prepaid the remaining $100 million principal amount outstanding under our 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. The average interest rate on the term loan for the year-to-date period ended July 30, 2013 (the payoff date) was 6.8%.
	Note payable to Contran - As discussed above, in February 2013 we entered into a promissory note with Contran that allows us to borrow up to $290 million. This new loan from Contran contains terms and conditions similar to the terms and conditions of the term loan, except that the loan from Contran is unsecured and contains no financial maintenance covenant. The independent members of our board of directors approved the terms and conditions of the loan from Contran. The note requires quarterly principal payments of $5.0 million which commenced in March 2013, with any remaining outstanding principal due by June 2018. Voluntary principal prepayments are permitted at any time without penalty. The note bears interest at LIBOR (with LIBOR no less than 1%) plus 5.125%, or the base rate (as defined in the agreement) plus 4.125%. We are required to use the base rate method until such time as both (1) the term loan discussed above has been fully repaid and (2) the European credit facility has been amended on terms satisfactory to Contran, at which time we would have the option to use either the base rate or LIBOR rate methods. The average interest rate on these borrowings as of and for the period from issuance to September 30, 2013 was 7.375%.
	Revolving European credit facility - During the first nine months of 2013, we borrowed €10 million ($12.8 million when borrowed) and repaid the entire outstanding balance of €20 million ($26.5 million when repaid) in August under our European credit facility. The average interest rate on these borrowings for the year-to-date period ended August 31, 2013 when paid off was 2.02%. At September 30, 2013, there were no outstanding borrowings under this facility.  Our European credit facility requires the maintenance of certain financial ratios.  At September 30, 2013, based on the current earnings before income tax, interest, depreciation and amortization expense of the borrowers, we would not have met the financial test if we had any net debt outstanding under this facility, and accordingly our effective available borrowing under this facility at September 30, 2013 is approximately $32.4 million, the aggregate amount of cash held by the borrowers, net of the borrowers’ other outstanding indebtedness.  We are in discussions with the lender to amend the facility to modify the covenant.  However, we do not currently anticipate the need to draw on this facility for the foreseeable future.
	Revolving North American credit facility - During the first nine months of 2013, we borrowed $90.3 million and repaid an aggregate $44.1 million. The average interest rate on these borrowings as of and for the period from borrowing to September 30, 2013 was 2.63% and 2.46%, respectively. At September 30, 2013 we had approximately $56.6 million  available for borrowing under this revolving facility.
	Canada - At September 30, 2013, an aggregate of Cdn. $7.5 million letters of credit were outstanding under our Canadian subsidiary’s loan agreement with the Bank of Montreal which exists solely for the issuance of up to Cdn. $10.0 million in letters of credit.
	In January 2013, we borrowed Cdn. $1.8 million (USD $1.8 million) under our Canadian subsidiary’s agreement with an economic development agency of the Province of Quebec, Canada which was recorded net of Cdn. $.5 million (USD $.5 million) imputed interest.
	Restrictions and other - Our European credit facility described above requires the borrowers to maintain minimum levels of equity, requires the maintenance of certain financial ratios, limits dividends and additional indebtedness and contains other provisions and restrictive covenants customary in lending transactions of this type. Our North American revolving credit facility and note payable to Contran also contain restrictive covenants. At September 30, 2013, there were no restrictions on our ability to pay dividends.
	We are in compliance with all of our debt covenants at September 30, 2013.

	Our income tax benefit in the third quarter of 2012 includes an incremental tax benefit of $11.1 million as we determined in the third quarter 2012 that due to global changes in our business, we would not remit certain dividends from our non-U.S. jurisdictions.  As a result, certain tax attributes were available for carryback to offset prior year tax expense.
	In the third quarter of 2012, France enacted certain changes in their income tax laws, including a 3% nondeductible surtax on all dividend distributions 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 in the period during which the dividend is declared and will be remitted to the French government in accordance with the applicable tax law.  During the third quarter of 2012, our French subsidiary distributed a $1.8 million dividend.  Distributions from our French subsidiary in 2013 are nil.  At September 30, 2013, our French subsidiary has undistributed earnings of approximately $10.9 million that, if distributed, would be subject to the 3% surtax.
	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 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 7). If the full amount of the proposed adjustment were ultimately to be assessed against us, the cash tax liability would be approximately $15.7 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 currently estimate that our unrecognized tax benefits may change by $3 million during the next twelve months related to certain adjustments to our prior year returns.

Commitments and Contingencies	'
	Note 12 - Commitments and contingencies:
	From time-to-time, we are involved in various environmental, contractual, product liability, patent (or intellectual property), employment and other claims and disputes incidental to our operations. In certain cases, we have insurance coverage for these items. 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 position, results of operations or liquidity beyond the accruals we have already provided.
	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 case in July 2011.  The defendants included 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 sought 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 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 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 was set for September 2013.  On September 10, 2013, and following the agreement by the three other defendants in the third quarter of 2013 to enter into settlement agreements with the class plaintiffs, we also entered into a settlement agreement with the class plaintiffs, without admitting any fault or wrongdoing, and agreed to pay an aggregate of $35 million (payable in two installments at specified times, expected to occur by mid-2014).  Following the service of the Class Action Fairness Notice and the Order of Final Approval from the court, we, and the other defendants, will be dismissed with prejudice from this matter.  Other operating expense in the third quarter of 2013 includes a $35 million charge related to this settlement.  See also Note 6.
	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.  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, Hawaii, Illinois, Iowa, Kansas, Maine, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Mexico, New York, North Carolina, North Dakota, Oregon, South Carolina, South Dakota, Tennessee, Utah, Vermont, West Virginia 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.  This matter had been stayed by the court pending a resolution in the Haley Paint Matter. 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.

	Noncurrent marketable securities (See Note 4)		34.5			34.5					—					—
	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 September 30, 2013, we had currency forward contracts to exchange:
	an aggregate of $45.0 million for an equivalent value of Canadian dollars at an exchange rate ranging from Cdn. $1.02 to Cdn. $1.06 per U.S. dollar.  These contracts with Wells Fargo Bank, N.A. mature from October 2013 through December 2014 at a rate of $3.0 million per month, subject to early redemption provisions at our option;
	an aggregate $25.0 million for an equivalent value of Norwegian kroner at exchange rates ranging from kroner 5.84 to kroner 6.14 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 October 2013 through April 2014; and
	an aggregate €16.0 million for an equivalent value of Norwegian kroner at exchange rates ranging from kroner 7.55 to kroner 8.07 per euro. These contracts with DnB Nor Bank ASA mature at a rate ranging from €2.0 million to €5.0 million per month in certain months from October 2013 through April 2014.
	The estimated fair value of our currency forward contracts at September 30, 2013 was a net liability of $.5 million, of which $.8 million is recognized as part of accounts and other receivables and $1.3 million is recognized as part of accounts payable and accrued liabilities, in our Condensed Consolidated Balance Sheets. There is also a corresponding $.5 million currency transaction loss recognized in our Condensed Consolidated Statement of Operations. We are not currently using hedge accounting for our outstanding currency forward contracts at September 30, 2013, and we did not use hedge accounting for any of such contracts we previously held in 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, 2012 and September 30, 2013.

	Common stockholders’ equity		1,062.1			2,260.2								920.5					1,794.7
	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 term loan is based on quoted market prices; however, these quoted market prices represent 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.

Organization_and_Basis_of_Pres1

Organization and Basis of Presentation (Policies)	9 Months Ended
	Sep. 30, 2013
Organization	'
	Organization - We are a majority-owned subsidiary of Valhi, Inc. (NYSE: VHI). At September 30, 2013, Valhi held approximately 50% of our outstanding common stock and NL Industries, Inc. (NYSE: NL) held an additional 30% of our common stock. Valhi owns approximately 83% of NL’s outstanding common stock. Approximately 94% of Valhi’s outstanding common stock is held by Contran Corporation and its subsidiaries. Substantially all of Contran’s outstanding voting stock is held by trusts established for the benefit of certain children and grandchildren of Harold C. Simmons (for which Mr. Simmons is the sole trustee), or is held directly by Mr. Simmons or other persons or entities related to Mr. Simmons. Consequently, Mr. Simmons may be deemed to control Contran, Valhi and us.
Basis of Presentation	'
	Basis of presentation - The unaudited Condensed Consolidated Financial Statements contained in this Quarterly Report have been prepared on the same basis as the audited Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2012 that we filed with the Securities and Exchange Commission (SEC) on March 12, 2013 (2012 Annual Report). In our opinion, we have made all necessary adjustments (which include only normal recurring adjustments) in order to state fairly, in all material respects, our consolidated financial position, results of operations and cash flows as of the dates and for the periods presented. We have condensed the Consolidated Balance Sheet and Statement of Stockholders’ Equity at December 31, 2012 contained in this Quarterly Report as compared to our audited Consolidated Financial Statements at that date, and we have omitted certain information and footnote disclosures (including those related to the Consolidated Balance Sheet at December 31, 2012) normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). Our results of operations for the interim periods ended September 30, 2013 may not be indicative of our operating results for the full year. The Condensed Consolidated Financial Statements contained in this Quarterly Report should be read in conjunction with our 2012 Consolidated Financial Statements contained in our 2012 Annual Report.
Marketable Securities	'
	Our marketable securities consist of investments in the publicly-traded shares of related parties: Valhi, NL and CompX International Inc. NL owns a 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 13. 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.
Derivatives and Hedging	'
	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.
