Mega Merger

The era of the mega-merger is well and truly here: BAT and Reynolds, tobacco giants, have agreed to merge with the former subsuming the latter.

This will create a giant tobacco firm, with a range of brands including Rothmans and Camel, and BAT hopes to make cost savings of $400m as a result. This implies that there are economies of scale resulting from the merger. 

The companies are aware of the fact that in the developed world, there's is a sunset industry as smoking rates are declining, and this will help protect their market position. I suspect it's only a matter of time before they move into the e-cigarette market in a big way - Camel, for example, have had fashion interests in the past.
