Related Party Transactions [Abstract] |
Related party transactions | Note 17 – Related party transactions: We may be deemed to be controlled by Ms. Simmons and the Family Trust. 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. From time to time, we may have loans and advances outstanding between us and various related parties, including Contran, 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 involved and appropriately reflect those credit risks in the terms of the applicable loans. When we borrow from related parties, we are generally able to pay a lower rate of interest than we would pay if we borrowed from unrelated parties. We paid Contran $10.4 million, $9.2 million and $10.3 million in interest on borrowings and unused commitment fees under Valhi’s Contran credit facility in 2021, 2022 and 2023, respectively. In February 2024, Kronos entered into a $53.7 million subordinated, unsecured term loan with Contran. See Note 9 for more information on the Kronos term loan with Contran and the Valhi credit facility with Contran. Under the terms of various intercorporate services agreements (ISAs) we enter into with Contran, employees of Contran provide us certain management, tax planning, financial and administrative services on a fee basis. Such fees are based on the compensation of individual Contran employees providing services for us and/or estimates of the time devoted to our affairs by such persons. Because of the 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 all of our subsidiaries, thus allowing certain Contran employees to provide services to multiple companies but only be compensated by Contran. We negotiate fees annually, and agreements renew quarterly. The net ISA fees charged to us by Contran aggregated $41.0 million in 2021, $41.2 million in 2022 and $37.8 million in 2023. At December 31, 2023, we had an aggregate 16.7 million shares of our Kronos common stock pledged as collateral for certain debt obligations of Contran. We receive a fee from Contran for pledging these Kronos shares, determined by a formula based on the market value of the shares pledged. We received $1.5 million in 2021, $1.2 million in 2022 and $.8 million in 2023 from Contran for this pledge. Contran and certain of its subsidiaries and affiliates, including us, purchase certain of their insurance policies and risk management services as a group, with the costs of the jointly-owned policies and services being apportioned among the participating companies. Tall Pines Insurance Company, our subsidiary, underwrites certain insurance policies for Contran and certain of its subsidiaries and affiliates, including us. Tall Pines purchases reinsurance from highly rated (as determined by A.M. Best or other internationally recognized ratings agency) third-party insurance carriers for substantially all of the risks it underwrites. Consistent with insurance industry practices, Tall Pines receives commissions from the reinsurance underwriters and/or assesses fees for certain of the policies that it underwrites. The aggregate amount paid under the group insurance program by us, our subsidiaries and our joint venture in 2021, 2022 and 2023 was $27.1 million, $25.2 million and $29.3 million, respectively, which amounts principally represent insurance premiums. The aggregate amounts paid under the group insurance program also include payments to insurers or reinsurers for the reimbursement of claims within our applicable deductible or retention ranges that such insurers and reinsurers paid to third parties on our behalf, as well as amounts for claims and risk management services and various other third-party fees and expenses incurred by the program. We expect these relationships will continue in 2024. With respect to certain of such jointly-owned 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, and in the event that the available coverage under a particular policy would become exhausted by one or more claims, Contran and certain of its subsidiaries and affiliates, including us, have entered into a loss sharing agreement under which any uninsured loss arising because the available coverage had been exhausted by one or more claims will be shared ratably amongst those entities that had 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 justify the risk associated with the potential for any uninsured loss. Contran and certain of its subsidiaries participate in a combined information technology data services program that Contran provides for primary data processing and failover. The program apportions its costs among the participating companies. The aggregate amount Kronos paid Contran for such services was $.3 million in each of 2021 and 2022 and $.4 million in 2023. Under the terms of a sublease agreement between Contran and Kronos, Kronos leases certain office space from Contran. Kronos paid Contran $.4 million in 2021, $.5 million in 2022 and $.6 million in 2023 for such rent and related ancillary services. We expect that these relationships with Contran will continue in 2024. Receivables from and payables to affiliates are summarized in the table below. ​

Sales of feedstock to LPC were $85.4 million in 2021, $106.9 million in 2022 and $135.1 million in 2023. The noncurrent payable to Contran for income taxes is discussed in Note 14.
