SeekingAlpha has an interesting article on it with some numbers I hasn't seen or heard yet. They seem to disagree a little with what I've been hearing elsewhere.
Specifically I'm interested to know if the article is generalizing when it says the majority of the cuts are to take place in October, or not.
