Held-to-Maturity Securities

Securities, usually long term debt that a company plans to keep until the borrower repays the debt.

Let’s say you bought a 5 year Exxon bond. The price of that bond can fluctuate in price. But those fluctuations mean nothing if you don’t plan to sell it. If you plan to hold securities to maturity, until the debt is repaid, you don’t record those fluctuations.
