Certificates of deposit
Farmers and Merchants State Bank in South Dakota states that CDs with a term of one year or less carry a 90-day-interest early-withdrawal penalty. For CDs with a term longer than one year, it states a 180-day-interest penalty. The CD section lists 3-month, 6-month, and 1- through 5-year options.
This is the Plankinton/White Lake, South Dakota institution identified by fmsbonline.com, not another bank with the same name. The page supplies the term thresholds but does not establish all inputs needed for an exact penalty formula, including day-count and principal treatment. Confirm the customer's opening or renewal terms.
