I just learned about Subscriber Accounts - I have been with USAA for 28 years (since I was 16), and have never heard of this.  Is this the same as the Dividend we get each year? 


No, it's not the same. The SA
is like stocks. If you were ever to cancel you USAA services they would give you that money. The dividend pays out each year and both are defpendant on how many products and the amount of money you put through them. More is more.
