Investments | (4) Investments As of March 31, 2023, we held investments in commercial paper, bonds, money market accounts, mutual funds, and equity securities. The commercial paper and bonds are considered held-to-maturity and are recorded at amortized cost in the accompanying consolidated balance sheets. The money market accounts, equity securities, and mutual funds are recorded at fair value in the accompanying consolidated balance sheets. The fair values of these investments were estimated using recently executed transactions and market price quotations. We consider as current assets those investments which will mature in the next 12 months including interest receivable on the long-term bonds. The remaining investments are considered non-current assets which we intend to hold longer than 12 months.
