What should I do if I don't know the void/maturity/expiration date?

These dates are critical to getting the most out of your investing and will be added to your library of Important Dates on Seraf. The documents you received should clearly indicate the void, maturity or expiration date for that particular transaction. Sometimes instead of a specific date, the wording may indicate that the shares or terms expire ten years from the initial closing, or other similar language. If you have difficulty finding the date, contact the company for clarification.
