You can find out how you're doing

Are your investments doing as well as you expected? Do you know what they are worth? Is it time to sell any of your investments? Your statement gives you information to help you answer these and other important questions.

You can make sure everything's in order

It's up to you to check your statement and report any errors promptly. Are all changes and transactions for the period properly reported? Does the statement say "bought" when it should say "sold?" Mistakes can and do happen. The longer you wait, the more difficult it is for the financial firm to fix an error.
