Chairman and CEO Mark Bertolini told analysts that the Hartford, Conn., insurer is committed to growing operating earnings next year, and it expects the floor for its performance to be around where it finishes this year.

Such results have become routine for the company. LinkedIn has surpassed Wall Street's expectations in all of its quarters as a publicly traded company and this one was no exception. But its outlook was below estimates and its shares fell in extended trading. LinkedIn booked a loss of $3.4 million, or 3 cents per share, in the July-September period. It had earned $2.3 million, or 2 cents per share, in the same period a year earlier. Adjusted earnings were 39 cents per share in the latest quarter, beating analysts' expectations by 7 cents.
