I was puzzled to learn, just this morning, that Schering has apparently withdrawn (see -- it's not there!) the November 14, 2008 "Investor FAQs" PDF file that contained the October 2008 Monthly IMS Vytorin/Zetia Scrip data.
Why did Schering-Plough take it down? I dunno. Repeating it here, now:
. . . . . . .Total US Cholesterol Management Market
Oct 2008: 20,292
Sept 2008: 19,666
Total Merck/Schering-Plough Franchise
Oct 2008: 2,186
Sept 2008: 2,171
Oct. 2008: 1,207
Sept 2008: 1,202
Oct. 2008: 978
Sept. 2008: 969. . . .
Importantly, once filed with the SEC, on a Form 8-K, it cannot simply be "disappeared". So, the original data remains safe at the SEC -- right here.
This creates a rather-odd single event of asymmetry, though -- all the other monthly updates are available on both the Schering website Investor FAQs index page, and at the SEC -- except the one filed Novemeber 14, 2008. What is up with that?
