1. Banks

2. Insurance companies

3. Investment firms

4. Credit unions

5. Savings and loan associations

Investors can purchase mid-term notes directly from the issuer or through a broker or financial advisor. It's important to carefully consider the creditworthiness of the issuer and the terms of the bond before making an investment in a mid-term note. Additionally, it may be helpful to consult with a financial professional to determine if mid-term notes are an appropriate investment for your goals and risk tolerance.
