Premiums are dependent on a number of variables: How much the buyer is set on the acquistition; how accretive it would be; whether the buyout is stock or cash (the former is a discount way to purchase others, and managements are generally more willing to be generous with paper); etc.
Given the mixed quality of BDX's assets, I would tend to agree with batman53 that a premium of 30% to perhaps 40% would be the most likely offer tended.
An offer which would be almost certainly declined.
Mr. Pelliginio where are you? The only salvation is if BDX is bought out. But then at what multiple times the share price? Will someone pay the average 40x share price? I am starting to think not. BDX has too many costly and non producing assets such as the white elephant Franklin Lakes Headquarters. You should see this monument to excess! I for one will hang on to my BDX shares for the time, hoping for a buy out. Perhaps we can get a 30% premiun over the current $26 per share price. This will put the price at about $34. I would take that and run.
Simple, The details of financial information as it applies to product lines and individual units and subsidiaries is not available to the general public in any of the SEC or annual report filings. Whenever articles mention specifics such as these then you know the source is the company. Remember that BD puts on a dog and pony show for the analyst every quarter to put a "positive spin" on its financial results. Some companies like J&J do not do this, frankly because they do not need to, since the financial performance speaks for itself.
