iTunes account balance

I would like to check the balance on my iTunes account, especially in light of the recent ebook lawsuit settlement. One would think the account balance would be listed on the Accounts screen, but no, it's not there. It used to show up in the upper right hand corner of the main screen but it's not there either. Can anyone tell me how to find this information? I'm using a 13" MacBook Air with the latest OS and iTunes. Thanks!
