Does Apple charge or request sth for IOS Admob Incomes?

Hi, the scenario is:

If I use IOS AdMob plugin in one of my games and release it as a Free game (with AdMob banner) the income would be saved into my PayPal account, but would Apple charge me for anything ? Do I need to send my bills to Apple to receive my money (like paid games) or do I just need to handle it with Admob and Paypal? I think with Android, it is pretty straight forward, you just get your money into your paypal account, thats all.

Thanks, Deniz
