I found the part of the TOS to which I was referring (I'm just providing this for reference...I meant to add it to my post the other day but forgot):
---------------------------
9. Confidentiality
You agree not to disclose Google Confidential Information without our prior written consent. "Google Confidential Information" includes: (a) all Google software, technology and documentation relating to the Services; (b) click-through rates or other statistics relating to Property performance as pertaining to the Services; (c) the existence of, and information about, beta features in a Service; and (d) any other information made available by Google that is marked confidential or would normally be considered confidential under the circumstances in which it is presented. Google Confidential Information does not include information that you already knew prior to your use of the Services, that becomes public through no fault of yours, that was independently developed by you, or that was lawfully given to you by a third party. Notwithstanding this Section 9, you may accurately disclose the amount of Google’s gross payments resulting from your use of the Services.
--------------------------
So in other words, according to Adsense TOS you can disclose gross payments but not individual metrics like CPM, CTR, etc.
