In fact, all of our print-to-mail operations are essentially automated now.
When you get something in a wrong envelope, it's usually a machine error. It usually means that a machine has picked up two pages instead of one, or somehow the flow between the envelope and the documents that are to go into it has been altered in some way within the machine. It's a machine or technical error.
We don't have, except in very rare instances, and again I'm not sure I could point to any, but it's very rare that we would be putting documents in envelopes by hand. We just deal with too much.
