1, see where you bought it. The purchased fund can be held for a long time, and there is no expiration time. If you buy a new fund, see when the closure period ends.

If the word redemption is gray, it is not due. If it shows redemption, it is due. The above is how the short-term three-month fund looks at the cycle.
