ISIN.net Assists with obtaining ISIN numbers for LTNs (long term notes)
Long term notes are those that come due in more than one year, are also very common. They differ from bonds mainly in the way the contract with the creditor is structured. A long term note is a promissory note that represents a loan from a bank or other creditor, whereas a bond is a more complex financial instrument that usually involves debt to many creditors. Analysts often do not distinguish between long-term notes and bonds because they have similar effects on the financial statements.
