ACL’s on Home Directory

Greetings! I've recently noticed my home directories that are created via CreateUser have ACL's associated with them. I can see this in terminal by doing ls -l and noticing the "+" next to all my permissions, which I believe indicated ACL's are present. So it looks something like: "drwx------+" for the Documents folder. If I look at Get Info things seems normal displaying owner (me) with "Read & Write" and everyone with "No Access" So I guess my question is, do I have to worry about these ACL's? I haven't noticed these a new out of box system so I was unsure. Thanks! Steve
