Why is Zions Bank considered high risk?

I bought a bunch of Zions Bank on discount earlier this year, and every time I look at it in my acct, it says 'High Risk' in red.

Is there something I am missing and do not know about? I live in Utah, and I know Zions Bank handles all the LDS (mormon) church tithing receipts (Mormons pay 10% of their income to the church, often giving it in cash or check to their local leader.)So Zions is getting tens of thousands, perhaps hundreds of thousands of dollars in cash every week throughout the entire state of Utah, and parts of Idaho, Wyoming and Arizona.

Furthermore, and this is more important, IMO, Zions Bank handles all the online tithing donations from around the world. I have a hard time imagining the $250B+ LDS church would ever let Zions Bank go under – There is no way they'd let anything threaten that constant flow of money from around the world, right?

So why the hell is Zions Bank considered high risk?
