NEW YORK (AP) - Caterpillar’s fourth-quarter net income rose compared with results weighed down by a large impairment charge a year ago. Its performance topped Wall Street’s view.

The U.S.-based company’s board approved a new $10 billion buyback. Caterpillar also provided a 2014 forecast above analysts’ estimates.

Its shares climbed more than 6 percent in premarket trading Monday.

For the period ended Dec. 31, Caterpillar Inc. - which makes mining gear, construction and forestry equipment and large power generators _ earned $1 billion, or $1.54 per share. That compares with $697 million, or $1.04 per share, a year earlier.

The prior-year period included an impairment charge of 87 cents per share, partially offset by a tax settlement of 45 cents per share.

Analysts surveyed by FactSet expected earnings of $1.27 per share for the latest quarter.

Revenue declined 10 percent to $14.4 billion from $16.08 billion, but still beat Wall Street’s forecast of $13.41 billion.

Full-year net income dropped to $3.79 billion, or $5.75 per share, from $5.68 billion, or $8.48 per share, in the previous year.

Annual revenue fell 16 percent to $55.66 billion from $65.88 billion, hurt mostly by a sharp decline in sales of new machines for mining.

For 2014, the company anticipates adjusted earnings of $5.85 per share on revenue of about $56 billion. Analysts predict earnings of $5.75 per share on revenue of $55.36 billion.

Caterpillar said it plans to repurchase about $1.7 billion shares of its common stock in the first quarter. The company said this move should complete its existing $7.5 billion repurchase program set to expire on Dec. 31, 2015. With the anticipated completion of the program, Caterpillar said its board approved a $10 billion repurchase program that is set to expire on Dec. 31, 2018.

The company’s stock gained $5.38, or 6.2 percent, to $91.55 in premarket trading about 75 minutes before the market open.
