Since Business deposits are not covered under TIS, are there some good arguments for or against giving the same info about APY and interest earned on business periodic statements as we give on consumer statements?

One argument against providing this information -- you'll have to decide if it's a "good" argument -- is that, in today's rate environment you might be reminding the business person just how low a rate you are paying on the business MMDA or savings account.

The flip side of this is that you might want to print the information if you tend to be on the high side of the market in your area.
