Note 6. Short-term Held-to-Maturity Investments

The Company invests excess cash balances in short-term U.S. Treasuries. Investments are classified based on the facts and circumstances present at the time of purchase. The appropriateness of that classification is subsequently reassessed at each reporting date. As of June 30, 2026, the Company has both the ability and intention to hold these investments until maturity and therefore has classified these investments as held-to-maturity and recorded them at amortized cost which approximates fair value and presented them in “Short-term investments, held-to-maturity” on the Condensed Balance Sheets. The fair value of the Company's short-term investments was based on quoted prices in active markets for these investments (Level 1). The income recognized for these investments was recorded within interest income on the Condensed Statements of Operations.
