Employee Benefit Plans

Note 10.   Employee Benefit Plans

We have a noncontributory, tax-qualified defined benefit pension plan covering employees who were hired prior to May 1, 2006. We also have an unfunded, nonqualified restoration plan that provides the pension plan formula benefits that cannot be provided by the qualified pension plan because of pay deferrals and the compensation and benefit limitations imposed on the pension plan by the Internal Revenue Code of 1986, as amended. Net periodic benefit cost related to the retirement and restoration plans was as follows:

	Three Months Ended September 30,						Nine Months Ended September 30,

Net Periodic Benefit Cost	$	4		$	5		$	14		$	15

During the nine months ended September 30, 2011, we made cash contributions of $23 million to the pension plan.
