NEW YORK - Health insurer WellPoint Inc is weighing job cuts as it grapples with enrollment declines stemming from the weak U.S. economy.

WellPoint, the largest U.S. health insurer by membership, has seen its enrollment pressured as its employer customers lay off workers.

As the economic environment changes, WellPoint reviews the size and skills of our workforce and makes adjustments as necessary, WellPoint spokeswoman Kristin Binns said in a statement.

We are examining ways we can operate more efficiently in 2010, which we believe is essential to allow us to invest for the longer term and to innovate for the benefit of our customers and members, Binns said in the statement.

The statement did not mention how many job cuts WellPoint was considering, and Binns did not expand on it.

WellPoint shares were off $1.10, or 2 percent, at $53.70 in morning trading on the New York Stock Exchange. (Reporting by Lewis Krauskopf, editing by Gerald E. McCormick)
