Here's the essence of a letter I've seen used in suspected kiting circumstances. Obviously, you will want to review it with management and possibly bank counsel before you use it.
"We have noted unusual activity recently in your ____ Bank deposit account # _________. Specifically, we note frequent deposits and drawing of checks between accounts at two or more banks. This activity, if done for the purposes of benefiting from the float it creates, is a prohibited activity. Be forewarned that we may, at our option and without warning, close your account if we believe such continued activity creates a risk of loss to us.
Examples of this type of unusual activity, some or all of which may have been observed in your account, include the following:
- Deposits drawn on other institutions by the same maker or signer.
- Large debits and credits of even dollar amounts.
- Regular or excessive drawings against uncollected funds.
- Several accounts with similar names owned or controlled by the same individuals.
We will closely monitor your account's activity over the next few days and weeks. If you have any questions about this matter, please contact us.
Sincerely,"
