During the first six months of 2024, we received gross proceeds from U.S. treasury bill maturities totaling $42.0 million. During the first six months of 2023, we had gross purchases of U.S. treasury marketable securities aggregating $50.0 million and received gross proceeds totaling $26.0 million related to U.S. treasury bill maturities.
Financing activities
Our board of directors declared a quarterly dividend of $.08 per share in each of the first, second and third quarters of 2024, and our board of directors declared a quarterly dividend of $.07 per share in each of the first, second and third quarters of 2023. The declaration and payment of future dividends, and the amount thereof, is discretionary and is dependent upon our financial condition, cash requirements, contractual obligations and restrictions and other factors deemed relevant by our board of directors. The amount and timing of past dividends is not necessarily indicative of the amount or timing of any future dividends which might be paid. There are currently no contractual restrictions on the amount of dividends which we may pay. In this regard, in August 2024, our board of directors declared a special dividend of $.43 per share on our common stock, par value $.125 per share. The special dividend is payable on August 29, 2024 to stockholders of record at the close of business on August 19, 2024. Additionally, in August 2024, CompX’s board of directors declared a special dividend of $2.00 per share on CompX’s Class A common stock, par value $.01 per share. CompX’s special dividend is payable on August 28, 2024 to CompX’s stockholders of record at the close of business on August 19, 2024.
Cash flows from financing activities in the first six months of each of 2023 and 2024 also include CompX dividends paid to its stockholders other than us.
Outstanding debt obligations
At June 30, 2024, NLKW had outstanding debt obligations of $.5 million under its secured revolving credit facility with Valhi, and CompX did not have any outstanding debt obligations. We are in compliance with all of the covenants contained in our secured revolving credit facility with Valhi at June 30, 2024. See Note 7 to our Condensed Consolidated Financial Statements.
Kronos had no outstanding borrowings at June 30, 2024 on its $225 million global revolving credit facility (the “Global Revolver”). Availability under the Global Revolver is subject to a borrowing base calculation, as defined in the agreement, and at June 30, 2024, the full $225 million was available for borrowings. Effective July 17, 2024, Kronos completed an amendment to its Global Revolver (the “Second Amendment”). Among other things, the Second Amendment increases the maximum borrowing amount from $225 million to $300 million, extends the maturity date to July 2029 and expands the facility to include LPC and LPC’s receivables and certain of its inventories in the borrowing base. The LPC acquisition was financed through borrowings of $132 million under Kronos’ Global Revolver with the remainder paid with cash on hand. In February 2024, Kronos exchanged €325 million principal amount of its outstanding 3.75% Senior Secured Notes due in September 2025 (the “Old Notes”) for newly issued €276.174 million aggregate outstanding 9.50% Senior Secured Notes due March 2029 (the “New Notes” and together with the Old Notes, the “Senior Secured Notes”) plus additional cash consideration of €48.75 million ($52.6 million). In connection with the exchange, Kronos entered into a $53.7 million unsecured term loan from Contran Corporation due in September 2029 (the “Contran Term Loan”). On July 30, 2024, Kronos’ wholly-owned subsidiary, KII, issued an additional €75 million principal amount of 9.50% Senior Secured Notes due 2029 (the “Additional New Notes”). The Additional New Notes were issued at a premium of 107.50% of their principal amount, plus accrued interest from February 12, 2024, resulting in net proceeds of approximately $90 million, after fees and estimated expenses. The Additional New Notes will be fungible with the New Notes, will be treated as a single series with the New Notes, and will have the same terms as the New Notes, other than their date of issuance and issue price. The proceeds from the Additional New Notes were used to pay down borrowings under Kronos’ Global Revolver. Subsequent to the issuance of the Additional Notes, in August 2024, the Contran Term Loan was amended to change the interest rate from 11.5% to 9.54%. The amended rate reflects the effective interest rate of the Additional New Notes plus an additional interest rate spread of 2% which is based upon comparable debt transactions at the time of issuance of the Additional New Notes.
The Contran Term loan is subordinated in right of payment to Kronos’ Senior Secured Notes and its Global Revolver. Kronos’ Senior Secured Notes, Contran Term Loan and Global Revolver contain a number of covenants and restrictions which, among other things, restrict its ability to incur or guarantee additional debt, incur liens, pay dividends or make other restricted payments, or merge or consolidate with, or sell or transfer substantially all of its assets to, another entity, and contain other provisions and restrictive covenants
