Defined Contribution and Defined Benefit Plans [Abstract] |
Defined Contribution and Defined Benefit Plans | Defined Contribution and Defined Benefit Plans We maintain two defined contribution savings plans that are intended to be tax exempt under Sections 401(a) and 501(a) of the IRC. Our non-union plan generally covers employees who are not covered by a collective bargaining agreement, and our union plan covers employees who are covered by a collective bargaining agreement. We recorded expenses for these plans of approximately $10 million, $9 million and $9 million for the years ended December 31, 2011, 2010 and 2009, respectively. Employer matching contributions are 100% of the first 5% of compensation a participant defers for the non-union plan. The employee deferral limit is 75% of compensation under both plans. As part of the Conectiv Acquisition, we assumed approximately $6 million of pension liability for approximately 130 grandfathered union employees who joined Calpine as a result of the Conectiv Acquisition and enrolled them into the New Development Holdings, LLC Union Retirement Plan, a defined benefit plan. PHI retained the pension liability associated with past service cost; however we are responsible for benefits for services after July 1, 2010 and future compensation increases related to past service. During the second half of 2010, we initiated a voluntary retirement incentive program which reduced our pension obligation by 31 employees. Under the New Development Holdings, LLC Union Retirement Plan, retirement benefits are primarily a function of age attained, years of participation, years of service, vesting and level of compensation. As of December 31, 2011 and 2010, our pension assets, liabilities and related costs were not material to us. As of December 31, 2011 and 2010, there were approximately $10 million and $8 million in plan assets and approximately $18 million and $15 million in pension liabilities, respectively. Our net pension liability recorded on our Consolidated Balance Sheets as of December 31, 2011 and 2010, was approximately $8 million and $7 million, respectively. For the years ended December 31, 2011 and 2010, we recognized net periodic benefit costs of approximately $1 million and $9 million, respectively. Net pension benefit costs for 2010 includes a one-time charge to pension expense for a voluntary retirement incentive program of approximately $8 million. The voluntary retirement incentive program was accepted by 31 of the 48 eligible employees that were retained as part of the Conectiv Acquisition allowing these employees the ability to commence receiving retirement benefits early without reducing their overall pension benefits. Our net periodic benefit cost is included in plant operating expense on our Consolidated Statements of Operations. As of December 31, 2011 and 2010, the total amount recognized in AOCI for actuarial losses related to pension obligation was approximately $3 million and nil, respectively. In making our estimates of our pension obligation and related costs, we utilize discount rates, rates of compensation increases and rates of return on our assets that we believe are reasonable. Due to relatively small size of our pension liability (which is not considered material), significant changes in these assumptions would not have a material effect on our pension liability. During 2011 and 2010, we made contributions of approximately $3 million and $8 million, respectively, and estimated contributions to the pension plan are expected to be approximately $2 million in 2012. Estimated future benefit payments to participants in each of the next five years are expected to be less than $1 million in each year.
