Related party transactions	Note 12—Related party transactions: We may be deemed to be controlled by Harold C. Simmons. See Note 1. Corporations that may be deemed to be controlled by or affiliated with Mr. Simmons sometimes engage in (a) intercorporate transactions such as guarantees, management and expense sharing arrangements, shared fee arrangements, joint ventures, partnerships, loans, options, advances of funds on open account, and sales, leases and exchanges of assets, including securities issued by both related and unrelated parties and (b) common investment and acquisition strategies, business combinations, reorganizations, recapitalizations, securities repurchases, and purchases and sales (and other acquisitions and dispositions) of subsidiaries, divisions or other business units, which transactions have involved both related and unrelated parties and have included transactions that resulted in the acquisition by one related party of a publicly-held minority equity interest in another related party. 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. 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. While certain of these loans may be of a lesser credit quality than cash equivalent instruments otherwise available to us, we believe we have evaluated the credit risks in the terms of the applicable loans. In this regard, in February 2010 we entered into an unsecured revolving demand promissory note with NL whereby we agreed to loan NL up to $8.0 million. In December 2012, this promissory note was amended whereby we agreed to loan NL up to $40 million. As amended, our loans to NL will bear interest at the prime rate less .75%, with all principal due on demand on or after March 31, 2014 (and in any event no later than December 31, 2014), with interest payable quarterly. The principal amount we lend to NL at any time is at our discretion. As of December 31, 2011 and 2012, we had no loans outstanding to NL. Interest income on our loans to NL was $23,000 in 2010 and nil in each of 2011 and 2012. In May 2010, for our investment purposes we purchased from NL for $15.0 million in cash a note receivable dated October 15, 2008 in the original principal amount of $15.0 million initially payable to NL by a third party. The promissory note bore interest at LIBOR plus 2.75%, payable monthly and all principal was due no later than October 2011. We amended our bank credit facility in May 2010 to enable us to borrow $5.0 million under the Credit Agreement, which we utilized along with $10.0 million of existing cash to complete the purchase of the note receivable. The purchase was also approved by the independent members of our board of directors. In October 2011, we collected in full the $15.0 million principal amount due to us under our promissory note receivable. Under the terms of an Intercorporate Service Agreement (“ISA”) with Contran, employees of Contran perform certain management, tax planning, financial, legal and administrative services for us on a fee basis. Such fees are based upon estimates of time devoted to our affairs by individual Contran employees and the compensation 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. Fees pursuant to these agreements aggregated $3.1 million in 2010, $3.4 million in 2011 and $3.7 million in 2012. This agreement is renewed annually, and we expect to pay $3.9 million under the ISA during 2013. Tall Pines Insurance Company (“Tall Pines”) and EWI RE, Inc. (“EWI”) provide for or broker certain insurance policies for Contran and certain of its subsidiaries and affiliates, including us. Tall Pines and EWI are subsidiaries of Valhi. Consistent with insurance industry practices, Tall Pines and EWI receive commissions from the insurance and reinsurance underwriters and/or assess fees for the policies that they provide or broker. The aggregate premiums we paid to Tall Pines and EWI were approximately $1.1 million in 2010, $1.3 million in 2011 and $1.2 million in 2012. These amounts principally included payments for insurance, 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 that these relationships with Tall Pines and EWI will continue in 2012. 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 these 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.
