Ethics - trade adjustment policy

The problem on page 261 of the Ethics book talks about interest adjustments for erronous trades made to a client’s account. Look at questions 3 and 4.

What section talks about crediting client accounts in case of trade allocation errors? The answers make it sound like it was covered in the text, but I cannot find it. Is this something that we are supposed to conclude on by ourselves?

it is on pg 255 of text

guess this means we need to know all of the guidelines of the cases as well

beautiful - thanks mcap.
