Check out which companies are making headlines before the bell:

Cigna– The insurer reported second quarter profit of $1.96 per share, excluding certain items, 12 cents above estimates, with revenue beating forecasts as well. Cigna said it benefitted from higher health care premiums and fees in its commercial business.
Newell Rubbermaid–The household products maker earned 59 cents per share for the second quarter, four cents above estimates. Revenue also beat estimates, with sales showing particular strength in tools and commercial products.

Yelp –Yelp earned four cents per share for the second quarter, surprising analysts who had expected a three cent loss. Revenue was also above estimate, but the consumer review website operator also reported growth in business accounts that fell short of some analyst forecasts.
