Under 230.4 of Reg. DD the account disclosures must state the grace period for an automatically renewable CD. Have any of you used a very short period for this period? If so how many days did you use and how effective was it?

You'll want to use at least five days if you want to use the grace period end and 20 advance days for your maturity notice under 230.5(b). Anything shorter, and you must send the notice at least 30 days before the current maturity.

Thanks John. I'd be afraid to go less than five days because of customer-service issues.
