Did you account for the fact that the text is rotated slightly to the right in the pdf copies? If you didn't, that could account for the over-hanging "f"s.
if you look at the image at the top of the page, the words are blown up enough for you to draw your own conclusion. To me, it doesn't seem that any rotated font is causing the issue. I have seen some talk that the apparent kerning is the result of multiple generations of photcopying and the fact that the documents from CBS are black and white images as opposed to gray scale. However, all of the "f"s in all of the documents overhang, so I think that is not really a persuasive argument.
