An Investment Date for optional investments will occur each Thursday. If that day is not a business day, the Investment Date will be the business day immediately following that Thursday. Optional investments must be received no later than two business days before an Investment Date. Automatic bank draft funds will be drawn on the 16th of each month or, if that date falls on a non-business day, the next business day. If the draft occurs on any day other than a Friday, the funds will be invested during the same week. Bank drafts occurring on a Friday will have an Investment Date in the following week.
