I'm going to ask Mr. Potter to comment. It's hard for me to answer that question myself, given that I can't speak for the individuals in question. It may not mean that they didn't have documentation at the time. What it does mean, however, is that there was no documentation on the file when it was reviewed. Whether that meant the documentation existed at the time or not, I don't know.
