Reynolds American Big Tobacco no longer holds sway over the American public. Fewer of us smoke or chew tobacco, but for those that still do, it remains an expensive habit--and quite profitable for the major tobacco producers. Reynolds American ( RAI), which owns five of the top 10 selling brands in the U.S. (including Camel and Pall Mall) is a poster child for the industry's still-robust financial picture. Like many other firms, Reynolds is squeezing out costs to expand margins, even as top-line growth remains anemic. That has helped boost Return on Equity (ROE) from 23.6% in 2010 to 26.3% in 2011, on its way to around 30% this year. The rising ROE has helped RAI to generate at least $2 billion in operating cash flow in four of the past five years, and that's led to steady dividend increases. Reynolds American's dividend rose 17% in 2011 to $2.15 a share, and it's up another 10% this year to $2.36 a share. That works out to be a 5.5% yield, which is among the highest among the tobacco producers.
