I keep a file on each MSB (we have 20). Each file contains all the account info, including ID's of the signers. I also track cash in's & out's & a sampling of deposit items on a quarterly basis. Our tellers & branch managers are reviewing deposits daily for business to business checks and any altered items. If you want to pm me with your email, I'd be happy to send you my review sheet. Our state examiners just left & had nothing but good things to say
