Item 8.01 - Other Events

The Company owns 411,723 shares of Visa Class B-2 common stock, carried at zero value on the Company’s balance sheet as of March 31, 2026. On April 13, 2026, Visa, Inc. (“Visa”) announced the commencement of a public offering to exchange Class B-2 common stock for a combination of shares of Class B-3 common stock and Class C common stock (“Exchange Offer”). The Company tendered all of its Visa Class B-2 shares and is awaiting notification of acceptance of that tender and the closing of the Exchange Offer. If the Company’s tendered shares are accepted and the exchange occurs in the second quarter of 2026, the Company expects to record a significant gain during the second quarter of 2026 based on the conversion privilege of the Class C common stock and the closing price of Visa Class A common stock. A full description of the terms of the Exchange Offer is set forth in Visa’s related Issuer Tender Offer Statement on Schedule TO and Prospectus, each dated April 6, 2026, publicly filed with the U. S. Securities and Exchange Commission.

Additionally, if the Company’s tendered shares are accepted and the exchange occurs in the second quarter of 2026, the Company may consider a plan to reposition a portion of its available for sale debt securities portfolio through the sale of securities, which may result in a significant loss during the second quarter of 2026. The timing and amount of the loss ultimately realized on the available for sale debt securities and the reinvestment assumptions may depend on many considerations, including market conditions, the amount of the gain recognized on the conversion privilege of the Visa shares, and other factors.
