What is the end of an investment period called?

The end of an investment period is commonly referred to as the "maturity date" or "expiration." At this point, the investment reaches its pre-determined term, and the principal amount is typically returned to the investor. For certain financial instruments, such as bonds or certificates of deposit, this marks the time when interest payments cease, and the final return of capital occurs. In the context of investment funds, it may also be referred to as the "liquidation" or "exit" phase.
