Equity [Abstract]
Stockholders' Equity	Note 7 – Stockholders’ equity: Our board of directors has previously authorized the repurchase of our Class A 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 will use cash on hand to acquire the shares. Repurchased shares will be added to our treasury and cancelled. During the first quarter of 2021, we purchased 50,000 shares of our Class A common stock in a market transaction for approximately $.8 million. We cancelled these treasury shares and allocated their cost to common stock at par value and additional paid-in capital. We made no treasury purchases during the first quarter of 2022. At March 31, 2022, 602,547 shares were available for purchase under prior repurchase authorizations. ​

Related Party Transactions [Abstract]
Related Party Transactions	Note 9 – Related party transactions: From time to time, we may 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, we have an unsecured revolving demand promissory note with Valhi under which, as amended, we agreed to loan Valhi up to $30 million. Our loan to Valhi, as amended, bears interest at prime plus 1.00%, payable quarterly, with all principal due on demand, but in any event no earlier than December 31, 2023. Loans made to Valhi at any time under the agreement are at our discretion. At March 31, 2022, the outstanding principal balance receivable from Valhi under the promissory note was $18.1 million. Interest income (including unused commitment fees) on our loan to Valhi was $.3 million and $.2 million for the three months ended March 31, 2021 and 2022, respectively.
