The Company recognized $416,004 of interest income from the accretion of its U.S. Treasury Strips in 2025. There was no interest income accretion recognized in 2024 as the Company did not hold any U.S. Treasury Strips during that year.

Consistent with the Company’s classification of its U.S. Treasury Strips as held to maturity, those securities scheduled to mature in the next twelve months after the reporting date are considered current assets and those having maturity dates more than twelve months after the reporting date are considered non-current assets. At December 31, 2025, the Company’s held to maturity securities were scheduled to mature as follows:

Margin Credit Line

In 2025, the Company secured a $19,000,000 margin credit line with a national bank, which bears interest at one percent above the base commercial rate. The Company’s investment securities held to maturity, specifically its U.S. Treasury Strips, serve as collateral for the margin credit line on which the Company had no outstanding borrowings at December 31, 2025. Availability under the margin credit line is subject to customary margin requirements based on the value of the pledged securities.
