Boeing Forecast Trails Estimates on Pension, Delays

Boeing Co. tumbled the most since November after forecasting 2011 profit that trailed analysts’ estimates amid delays to its two marquee jets, higher pension expenses and scaled-back defense spending in the U.S.

Net income will be $3.80 to $4 a share, including an increase of 58 cents a share in pension expenses, the Chicago-based company said in a statement. That lagged behind the $4.53-a-share average estimate of 26 analysts surveyed by Bloomberg.
