I don't think that's clear at all, and I don't think it's helpful for you to handwave those other risks as if everybody already knows what they are. What is an example of one other risk?

The only other risk I can think of is interest rate "risk" - the "risk" that rates go up right after you buy a bond, and you'll wish that you'd waited and gotten the better deal. But I wouldn't really consider that a true risk. The bond you bought is still perfectly good, so that's just plain old buyer's remorse.
