FSCPA,
Not to sound picky by saying this, but just wanted to correct something you mentioned. You said:
"When I read about the assertions, they make complete sense, like confirms gives you comfort over rights and obligation as well as valuation."
I was extremely confused by assertions at first as well, so I wanted to correct what you mentioned to help avoid the same mistake I did. Confirmations DO NOT confirm the valuation assertion. Although that may seem contradictory, they only provide assurance over existence, and rights and obligations.
For instance, imagine that you are a retailer that purchased inventory from the company being audited. You have a $100,000 AP on your books that you owe to audited company. You receive a positive confirmation saying that you owe $90,000. Now, if you are that company, are you likely to report to the auditors that the audited company made a mistake and that they only have $90,000 recorded as their AR from you? (completeness) Not likely. Therefore, by replying to the confirmation, you are telling the auditor that this payable DOES indeed exist, and that the company has a right to receive that money. In addition, an auditor has no way of knowing if the retailer has the funds available to pay the payable. So it may only be valued at $50,000, because the company may be insolvent (valuation).
So that is a long winded way of saying confirmations are ONLY for rights/obligations and existence. I hope that helps and it took me a while to catch on to that. It is also mentioned on Becker page A4-37,
